Ourrevenue’s year-on-year growth rate recovered to 10% in the fourth quarter of 2020 and furtherincreased to 42% in the first quarter and 48% in the second quarter of 2021, as the COVID-19pandemic was gradually contained in China and the advertising demand recovered accordingly.

We generate revenues primarily from customers who purchase advertising and marketingservices, and, to a lesser extent, from fee-based revenues, such as VIP membership. Revenuesgenerated from advertising and marketing services accounted for 88% of our total revenues in2020 and 86% of our total revenues in the six months ended June 30, 2021. We had incomefrom operations of US$609.3 million in 2018, US$597.6 million in 2019 and US$506.8 millionin 2020. Our income from operations increased from US$164.2 million in the six months endedJune 30, 2020 to US$301.8 million for the same period in 2021. Our operating margin, beingthe ratio of income from operations to total revenues, reached 30.0% in 2020 and 29.2% in thefirst six months ended June 30, 2021.

COMPETITIVE LANDSCAPE

In China, there are several types of social platforms dedicated to serving users’ needs tovirtually connect with each other. Compared with social network platforms, where socialrelationship is primarily symmetric and reciprocal, social media platforms facilitate thebuild-out of asymmetric social relationship and address users’ differentiated social needs in thepublic arena. Furthermore, among the leading social media platforms in China, some focus onspecific content formats such as video and live streaming, while others provide comprehensivecontent formats to cater to the diverse user needs. Platforms with more diverse content formatsand more vibrant content creation ecosystems are better equipped to address the evolving userneeds with diverse backgrounds and interests.

Weibo is one of the top 5 social platforms and the top 3 social media platforms in China interms of MAUs and DAUs in June 2021, according to the CIC report.

Weibo operates in a highly competitive industry which is rapidly changing due to the quicklyevolving market demand and user preferences. Driven by the increasing popularity of socialplatforms, the penetration rate for the social platforms, measured by the ratio of overall socialplatform users to all mobile users, has already come to hover near the 100% mark in 2020. Newuser acquisition has been one of the key challenges that each of the social platforms faces. Theindustry is evolving rapidly while witnessing rising competition for traffic and user time.Industry players compete for audiences and content with other major Chinese internetcompanies that provide online media as well as offline media companies. The user growth rateof established social media platforms may slow over time as the size of the user base increasesand as they achieve higher market penetration in China’s internet population. For a moredetailed discussion on and a comparison of key metrics of social platforms and social mediaplatforms in China, see also “Industry Overview — Competitive Landscape For Social MediaPlatforms” and “Industry Overview — Competitive Landscape For Social Platforms.”

(4) We adopted ASU 2016-13, “Financial Instruments — Credit Losses (Topic 326), Measurement of Credit Losseson Financial Instruments” in the fiscal year of 2020. The guidance requires the measurement and recognitionof expected credit losses for financial assets held at amortized cost that an entity does not expect to collect overthe asset’s contractual life, considering past events, current conditions, and reasonable and supportableforecasts of future economic conditions.

(5) We adopted ASU 2016-01 “Classification and Measurement of Financial Instruments” beginning the firstquarter of fiscal year 2018. After the adoption of the new accounting update, we measure investments in equitysecurities, other than equity method investments, at fair value through earnings. For those investments withoutreadily determinable fair values, we elected to record these investments at cost, less impairment, and plus orminus subsequent adjustments for observable price changes. Changes in the basis of these investments arereported in current earnings.

(6) Investment related impairment includes impairment charges to equity investments, investment prepayments,and loans to and interest receivable from related parties.

(7) Each ADS represents one Class A ordinary share.

Net income attributable to Weibo’s shareholders decreased from US$250.5 million for the sixmonths ended June 30, 2020 to US$130.8 million for the six months ended June 30, 2021. Thedecrease primarily resulted from (i) total cost and expenses increasing by US$184.9 million,from US$546.6 million for the six months ended June 30, 2020 to US$731.5 million for thesame period in 2021, (ii) net income from non-operations of US$142.4 million for the sixmonths ended June 30, 2020, compared to net loss from non-operations of US$110.0 millionfor the same period in 2021, which primarily resulted from US$69.5 million of fair valuechange loss from investments in marketable equity securities and US$66.6 million ofinvestment related impairment, and (iii) partially offset by total revenues increasing byUS$322.6 million, from US$710.8 million for the six months ended June 30, 2020 toUS$1,033.4 million for the same period in 2021.

Net income attributable to Weibo’s shareholders decreased from US$494.7 million in 2019 toUS$313.4 million in 2020. The decrease was mainly due to (i) total revenues decreasing byUS$77.0 million, from US$1,766.9 million in 2019 to US$1,689.9 million in 2020 and (ii) netloss from non-operations amounting to US$130.9 million in 2020, which included non-cashinvestment-related impairment of US$212.0 million, compared to net income from non-operations of US$4.8 million in 2019.

Net income attributable to Weibo’s shareholders decreased from US$571.8 million in 2018 toUS$494.7 million in 2019. The decrease largely resulted from (i) total cost and expensesincreasing by US$60.0 million, from US$1,109.3 million in 2018 to US$1,169.3 million in2019, (ii) net income from non-operations of US$59.6 million in 2018, decreasing to netincome from non-operations of US$4.8 million in 2019, and (iii) partially offset by totalrevenues increasing by US$48.4 million, from US$1,718.5 million in 2018 to US$1,766.9million in 2019.

Under our weighted voting rights structure, our share capital comprises Class A ordinary sharesand Class B ordinary shares. Each Class A ordinary share entitles the holder to exercise onevote and each Class B ordinary share entitles the holder to exercise three votes respectively,on all matters that require a shareholder’s vote.

We have applied for, and the Stock Exchange has granted us, a waiver from strict compliancewith Rule 19C.07(3) of the Hong Kong Listing Rules, which requires that the appointment,removal and remuneration of auditors must be approved by a majority of a listed company’smembers or other body that is independent of the listed company’s board of directors.

The minimum stakerequired to do so must not be higher than 10% of the voting rights, on a one vote per sharebasis, in the share capital of the issuer, while the minimum stake as currently set out in ourCompany’s Articles is at least two shareholders holding not less than one-third of the totalvoting rights in the paid up capital of our Company. Rule 19C.07(4) requires a general meetingto be held each year as the qualifying issuer’s annual general meeting.

We have applied for, and the Stock Exchange has granted us, a waiver from strict compliancewith Rule 19C.07(4) and 19C.07(7) of the Hong Kong Listing Rules, on the condition that wewill put forth resolutions at the First GM to revise the Articles, so that (i) the minimum stakerequired to convene an extraordinary general meeting and add resolutions to a meeting agendawill be one-tenth of the voting rights, on a one vote per share basis, in the share capital of theCompany; (ii) the quorum for a general meeting of the Company will be lowered from thecurrent one or more shareholders holding at least one-third of the aggregate voting power ofthe Company to one or more shareholders holding at least 10% of the aggregate voting powerof the Company; and (iii) we will hold an annual general meeting each year; and we haveobtained an irrevocable undertaking from our controlling shareholder prior to the date of thisdocument to be present and vote in favor of the proposed resolutions outlined above with aview to ensuring that there may be adequate quorum votes in favor of such resolutions.

SUMMARY

– 15 –

As we are seeking a listing as a Grandfathered Greater China Issuer pursuant to Chapter 19Cof the Listing Rules with a WVR structure, certain shareholder protection measures andgovernance safeguards under Chapter 8A of the Hong Kong Listing Rules (Weighted VotingRights) do not apply to us pursuant to Rule 19C.12 and our Articles differ from Chapter 8A ina number of ways, including the following:

• Chapter 8A prohibits the increase in the proportion of shares with WVRs after the Listingand, where there is a reduction in the number of issued shares, requires shares with WVRsto be reduced proportionately. Our Articles do not contain such restrictions on the ClassB ordinary shares;

• Chapter 8A requires (a) amendments to a listed issuer’s constitutional documents, (b)variation of rights attached to any class of shares, (c) the appointment or removal of anindependent non-executive director, (d) the appointment or removal of auditors and (e)the voluntary winding-up of a listed issuer to be subject to shareholder approval on a onevote per share basis. Our Articles do not contain such provisions;

• we do not have a corporate governance committee. Therefore, there is not a charter thatcontains the terms otherwise required under Rule 8A.30 and Code Provision D.3.1 ofAppendix 14 to the Hong Kong Listing Rules. For more details of the charter of ourcorporate governance committee, please see “Directors and Senior Management — BoardPractices”; and

• the independent non-executive directors of a listed issuer with a WVR structure must besubject to retirement by rotation at least once every three years under Chapter 8A,whereas our Articles do not provide for a term of office for our directors.

• the WVR beneficiary’s voting rights must cease if the beneficiary is deceased, no longera member of the board, or deemed by the Hong Kong Stock Exchange to no longer meetthe requirements of or be incapacitated for the purpose of performing his duties as adirector. Notwithstanding the foregoing, the existing Articles stipulate that, if at any timeSINA and its affiliates in aggregate hold less than 5% of the issued Class B ordinaryshares in our capital, the WVR beneficiaries’ weighted voting rights will cease.Furthermore, we will make certain changes to the Articles at the First GM to the effectthat, if the Class B ordinary shares are no longer under the control of the existing WVRbeneficiaries or their affiliates, all of the relevant Class B ordinary shares held by it shallbe automatically converted into Class A ordinary shares. For further details, see thesection headed “Waivers and Exemptions — Shareholder Protection Requirements —Other Proposed Amendments to the Articles”.

Prospective investors are advised to be aware of the potential risks of investing in companieswith a WVR structure, in particular that the interests of the WVR beneficiaries may notnecessarily always be aligned with those of our Shareholders as a whole, and that the WVRbeneficiaries will be in a position to exercise their higher voting power to influence the affairsof our Company and the outcome of shareholders’ resolutions, irrespective of how othershareholders vote. Prospective investors should make the decision to invest in the Companyonly after due and careful consideration. For further information about the risks associated withthe WVR structure adopted by the Company, please refer to “Risk Factors — Risks Related toOur Corporate Structure.”

As a result, our Articles provide less shareholder protection and have fewer governancesafeguards than if our Company were subject to Chapter 8A in its entirety.

NO MATERIAL ADVERSE CHANGE

Our directors confirm that, as of the date of this document, there has been no material adversechange in our financial or trading position since June 30, 2021 (being the date on which thelatest audited consolidated financial information of our Group was prepared) and there hasbeen no event since June 30, 2021 which would materially affect the information shown in ourconsolidated financial statements included in the Accountant’s Report in Appendix IA to thisdocument.

IMPACT OF COVID-19 AND RECENT DEVELOPMENT

The COVID-19 pandemic has had, and, together with any subsequent outbreaks driven by newvariants of COVID-19, may continue to have, a significant impact on our operations andfinancial results. The outbreak of COVID-19 has caused our advertising and marketingcustomers to reduce their advertising budgets, which has affected our advertising revenues andfinancial performance in the year of 2020, particularly in its first half. The COVID-19pandemic has caused negative impact to our total revenues, slower collection of accountsreceivables, and additional allowance for credit losses. Our advertising business has beengradually recovering, underpinned by improved advertiser sentiment, following the effectivecontrol of the domestic outbreaks and work resumption. In China, business activities havelargely resumed, governmental emergency measures have been significantly relaxed, and thegeneral economy is gradually recovering. Recently, there has been an increasing number ofCOVID-19 cases, including the COVID-19 Delta variant cases, in multiple cities in China. TheChinese local authorities have reinstated certain measures to keep COVID-19 in check,including travel restrictions and stay-at-home orders, and we may have to adjust variousaspects of our operations. In addition, the highly-transmissible Delta variant of COVID-19 hascaused authorities in various countries to reimpose restrictions such as mask mandates, curfewsand prohibitions on large gatherings. There remain significant uncertainties surroundingCOVID-19, including the existing and new variants of COVID-19, and its further developmentas a global pandemic, including the effectiveness of vaccine programs against existing and anynew variants of COVID-19, and their impacts on our customers’ advertising budget andspending more broadly. The extent of any business disruption and the related impact on ourfinancial results and outlook cannot be reasonably estimated at this time. See also “RiskFactors — Risks Relating to Our Business — We face risks related to health epidemics andother outbreaks, such as the outbreak of COVID-19, as well as natural disasters, which couldsignificantly disrupt our operations and adversely affect our business, financial condition orresults of operation.”

• Advertising and marketing revenues. Advertising and marketing revenues increased by38% from US$1,032.7 million in the nine months ended September 30, 2020 toUS$1,430.0 million in the nine months ended September 30, 2021. Mobile advertisingrevenues accounted for approximately 93% of our total advertising and marketingrevenues in the nine months ended September 30, 2021, compared to 90% in the ninemonths ended September 30, 2020, benefiting from the growth of advertiser preferences.The total number of advertisers was 0.8 million in the nine months ended September 30,2021, compared to 1.4 million in the nine months ended September 30, 2020, while theaverage spending per advertiser (excluding Alibaba) increased by 152% from US$649 inthe nine months ended September 30, 2020 to US$1,637 in the nine months endedSeptember 30, 2021, both of which were primarily due to the churn of individualcustomers with relatively lower advertising budgets.

Revenues from advertising customers (excluding Alibaba) increased by 42% fromUS$940.2 million in the nine months ended September 30, 2020 to US$1,335.9 millionin the nine months ended September 30, 2021, primarily attributable to a broad-basedincrease in advertising demand and strong sales execution. Revenues generated fromAlibaba as an advertiser increased by 2% from US$92.5 million in the nine months endedSeptember 30, 2020 to US$94.1 million in the nine months ended September 30, 2021.The advertising spending from Alibaba highly correlates to its own business operation,especially its marketing strategies, which fluctuates from time to time.

• Value-added services revenues. Value-added services revenues increased by 47% fromUS$143.8 million in the nine months ended September 30, 2020 to US$210.8 million inthe nine months ended September 30, 2021. The increase primarily attributable to theincrease of game-related revenues from US$0.9 million for the nine months endedSeptember 30, 2020 to US$78.1 million for the nine months ended September 30, 2021,contributed by the interactive entertainment company acquired in the fourth quarter of2020 and incremental revenues from online game services, partially offset by the decreaseof revenue from live streaming business from US$30.7 million to US$11.9 million as aresult of intense market competitions.

Costs and Expenses

Our costs and expenses increased by 32% from US$851.4 million in the nine months endedSeptember 30, 2020 to US$1,125.9 million in the nine months ended September 30, 2021.

• Cost of Revenues. Cost of revenues increased by 28% from US$214.9 million in the ninemonths ended September 30, 2020 to US$275.3 million in the nine months endedSeptember 30, 2021.

• Sales and Marketing. Our sales and marketing expenses increased by 39% from US$316.5million in the nine months ended September 30, 2020 to US$439.2 million in the ninemonths ended September 30, 2021. The increase was primarily due to an increase ofUS$82.7 million in marketing spend and promotional activities, and an increase ofUS$34.0 million in personnel-related expenses.

• Product Development. Our product development expenses increased by 35% fromUS$233.9 million in the nine months ended September 30, 2020 to US$316.8 million inthe nine months ended September 30, 2021. The increase was primarily attributable to anincrease of US$54.9 million in personnel-related expenses, an increase of US$6.4 millionin stock-based compensation, and an increase of US$13.4 million in amortization ofintangible assets.

• General and Administrative. Our general and administrative expenses increased by 10%from US$86.1 million in the nine months ended September 30, 2020 to US$94.6 millionin the nine months ended September 30, 2021. The increase was primarily due to theincrease of US$35.8 million in personnel-related expenses and an increase of US$6.5million in professional services fees. The increase was partially offset by a decrease ofUS$39.7 million in provision of allowance for credit losses.

Investment Related Impairment

Compared to the interest expense for the nine months ended September 30, 2020, the increasein interest expense for the nine months ended September 30, 2021 was mainly due to the 2030Notes issued in July 2020.

RECENT REGULATORY DEVELOPMENTS

Cybersecurity

On July 30, 2021, the State Council promulgated the Regulations on Security Protection ofCritical Information Infrastructure (《關鍵信息基礎設施安全保護條例》), effective onSeptember 1, 2021, which provides that a “critical information infrastructure” has the meaningof an important network facility and information system in important industries such as, amongothers, public communications and information services, as well as other important networkfacilities and information systems that may seriously endanger national security, the nationaleconomy, the people’s livelihood, or the public interests in the event of damage, loss offunction, or data leakage. The competent governmental departments and supervision andmanagement departments of the aforementioned important industries will be responsible fororganizing the identification of critical information infrastructures in their respectiveindustries.

On July 10, 2021, the CAC published a discussion draft of the amended Measures forCybersecurity Review (《網絡安全審查辦法(修訂草案徵求意見稿)》), which provides thatcertain operators of critical information infrastructure purchasing network products andservices, and data processors (together with the operators of critical information infrastructure,the “Operators”) carrying out data processing activities, which affect or may affect nationalsecurity, or Operators holding over one million users’ personal information when listing abroad(國外上市), must apply with the Cybersecurity Review Office for a cybersecurity review. Fordetails, see “Regulatory Overview — Regulations on Information Security.” As a majorinternet platform, we are at risk of being deemed to be an Operator, which, however, is subjectto significant uncertainties as explained below.

• Under the current PRC cybersecurity laws and the draft of the amended Measures forCybersecurity Review, operators of “critical information infrastructure” that intend topurchase internet products and services that will or may affect national security mustapply for a cybersecurity review. However, as advised by our PRC Legal Adviser,although several PRC laws and regulations have provided the definition of “criticalinformation infrastructure,” the scope of potential operators of “critical informationinfrastructure” remains broad and unclear and the identification of any specific criticalinformation infrastructure is subject to industry-specific identification rules promulgatedby relevant regulators and the notice from the relevant regulators, pursuant to theRegulations on Security Protection of Critical Information Infrastructure. In addition, thedefinition and scope of activities of data processing that will or may affect nationalsecurity is similarly unclear and subject to the regulatory interpretation.

• Although the internet products and services we purchase are primarily bandwidth,copyright content and marketing services, we may be subject to cybersecurity reviewwhen purchasing them in the future. As of the date of this document, we have not beeninvolved in any investigations or cybersecurity reviews by the CAC for making thosepurchases of internet products and services, and we have not received any inquiry, notice,warning, or sanction in such respect.

An Operator could be required to fulfill various obligations, including setting up a specialsecurity management organization, organizing regular cybersecurity education and training,formulating emergency plans for cybersecurity incidents and conducting regular emergencydrills, and we have already performed the aforementioned measures. As a major internetplatform, we are at risk of being deemed to be an operator of “critical informationinfrastructure” and a data processor meeting the above criteria under PRC cybersecurity laws.In such case, we would be required to fulfill various obligations as required under PRCcybersecurity laws and other applicable laws specifically for operators of “critical informationinfrastructure” and a cybersecurity review for our activities would be required, which maydisrupt our operations and adversely affect our business, results of operations and financialcondition. We have not fulfilled obligations that are only applicable and available if beingrecognized as an operator of “critical information infrastructure” such as conducting networksecurity inspections and risk assessments on critical information infrastructure at least once ayear either through self-assessment or through a cybersecurity service agency, timelycorrecting any security issues discovered, and reporting relevant matters as required by thesecurity protection departments. As we have not been notified that we are recognized as anoperator of critical information infrastructure by any PRC regulatory authority as of the dateof this document, these obligations are currently not applicable to us. In addition, we have notbeen involved in any investigations or cybersecurity reviews by the CAC as an operator of“critical information infrastructure” during the Track Record Period and up to the date of this

document, and we have not received any inquiry, notice, warning or sanction in such respect.Additional compliance efforts could disrupt our operations and adversely affect our business,results of operations and financial condition.

As there is no timetable as when this discussion draft of the amended Measures forCybersecurity Review will be enacted, substantial uncertainties exist with respect to itsenactment timetable, final content, interpretation and implementation. See “Risk Factors –Substantial uncertainties exist with respect to the interpretation and implementation ofcybersecurity related regulations and cybersecurity review as well as any impact these mayhave on our business operations.”

On November 14, 2021, the CAC published a discussion draft of the Administrative Measuresfor Internet Data Security (《網絡數據安全管理條例(徵求意見稿)》), or the Draft Measuresfor Internet Data Security, which requires a data processor to apply for cybersecurity review,among others, in the event of its listing in Hong Kong which affects or may affect nationalsecurity. As of the date of this document, this draft has not been formally adopted. Our PRCLegal Adviser is of the view that substantial uncertainties exist with respect to the enactmenttimetable, final content, interpretation and implementation, especially the detailedinterpretation of the standard for determining whether a listing in Hong Kong “affects or mayaffect national security”. And the Joint Sponsors’ PRC legal adviser concurs with theaforementioned view of the Company’s PRC Legal Adviser. If the Draft Measures for InternetData Security is enacted as proposed, in the event that any of our capital raising activities isrequired to apply for cybersecurity review, we will need to obtain approval or clearance fromthe regulatory authorities, which is subject to uncertainties. See “Risk Factors – Substantialuncertainties exist with respect to the interpretation and implementation of cybersecurityrelated regulations and cybersecurity review as well as any impact these may have on ourbusiness operations.”

However, as advised by our PRC Legal Adviser, we are of the view that, the Draft Measuresfor Internet Data Security will not have any immediate material impact on the proposedListing, on the following basis (i) this is a draft regulation for comment and not currently ineffect, (ii) this draft does not contain retrospective provisions that would have a materialimpact on the proposed Listing, and (iii) as of the date of this document, we have not beeninvolved in review or investigation by the CAC with respect to the Draft Measures for InternetData Security. As we have implemented data and technology system risk management tocomply with data security and data protection requirements, see “Business — RiskManagement and Internal Control — Data and technology system risk management,” wecurrently do not foresee any material impediments for us to gradually take measures under theguidance of the relevant regulators to prepare ourselves for compliance with the regulations inall material respects, once promulgated.

The Joint Sponsors have (i) discussed with the Company’s management on the Company’scybersecurity measures and the potential impact of the Draft Measures for Internet DataSecurity on the Group’s business; and (ii) discussed with the Company’s PRC legal advisersand the Joint Sponsors’ PRC legal advisers on the legal status and implications of the DraftMeasures for Internet Data Security in relation to the Company’s proposed Listing in HongKong. Based on the foregoing and as advised by the Company’s PRC Legal Adviser and theJoint Sponsors’ PRC legal adviser, and taking into account the substantial uncertainties withrespect to the enactment timetable, final content, interpretation and implementation discussedabove, nothing has come to the attention of the Joint Sponsors as non-legal experts that wouldlead them to cast doubt on the views of the Company and the PRC Legal Advisers as set outabove.

Anti-monopoly and competition

On August 17, 2021, the State Administration for Market Regulation issued a discussion draftof Provisions on the Prohibition of Unfair Competition on the Internet (《禁止網絡不正當競爭行為規定(公開徵求意見稿)》), under which business operators should not use data oralgorithms to hijack traffic or influence users’ choices, or use technical means to illegallycapture or use other business operators’ data. Furthermore, business operators are not allowedto (i) fabricate or spread misleading information to damage the reputation of competitors, or(ii) employ marketing practices such as fake reviews or use coupons or “red envelopes” toentice positive ratings.

On September 11, 2020, the Anti-Monopoly Commission of the State Council issuedAnti-Monopoly Compliance Guideline for Operators (《經營者反壟斷合規指南》), whichrequires operators to establish anti-monopoly compliance management systems under the PRCAnti-Monopoly Law to manage anti-monopoly compliance risks. On February 7, 2021, theAnti-Monopoly Commission of the State Council published Anti-Monopoly Guidelines for theInternet Platform Economy Sector (《國務院反壟斷委員會關於平台經濟領域的反壟斷指南》)that specified circumstances where an activity of an internet platform will be identified asmonopolistic act as well as concentration filing procedures for business operators, includingthose involving variable interest entities. In August 2021, the SAMR issued two investigationnotices to Weimeng Chuangke regarding alleged illegal concentration of business operatorsunder the Anti-Monopoly Law, among which, one resulted in a fine of RMB500,000 forconcentration of business operators without prior filing pursuant to the Anti-Monopoly Law(中華人民共和國反壟斷法) and the other one is still under investigation as of the date of thisdocument. Weimeng Chuangke is actively cooperating with the SAMR on such investigation.We are not able to predict the status or the results of the investigation at this stage. Accordingto the PRC Anti-Monopoly Law (中華人民共和國反壟斷法), if a business operator carries outa concentration in violation of the law, the relevant authority shall order the business operatorto terminate the concentration, dispose of the shares or assets or transfer the business withina specified time limit, or take other measures to restore the pre-concentration status, andimpose a fine of up to RMB500,000. As such, our PRC legal adviser is of the view that wecould be subject to fines of up to RMB500,000 and other legal actions by the SAMR for suchconcentration.

On October 23, 2021, the Standing Committee of the National People’s Congress issued adiscussion draft of the amended Anti-Monopoly Law, which proposes to increase the fines forillegal concentration of business operators. The draft also proposes that the relevant authorityshall investigate a transaction where there is any evidence that the concentration has or mayhave the effect of eliminating or restricting competitions, even if such concentration does notreach the filing threshold. We are of the view that the strengthened enforcement of theAnti-Monopoly Law could result in investigations on our acquisition transactions conducted inthe past and make our acquisition transactions in the future more difficult due to the prior filingrequirement. See “Risk Factors — Any failure or perceived failure by us to comply with theAnti-Monopoly Guidelines for Internet Platforms Economy Sector and other PRC anti-monopoly laws and regulations may result in governmental investigations or enforcementactions, litigation or claims against us and could have an adverse effect on our business,financial condition and results of operations.”

Algorithm recommendation

On August 27, 2021, the CAC issued a discussion draft of Administrative Provisions onAlgorithm Recommendation of Internet Information Services (《互聯網信息服務算法推薦管理規定(徵求意見稿)》), which, among others, requires algorithm recommendation service

providers to publicly disclose the basic principles, purposes, intention, and operatingmechanism of their algorithm-related products. If this draft is enacted as proposed, we mayneed to further adjust our business and operations. We have publicly disclosed the operationmechanism for “Weibo hot search” in the Weibo Hot Search Management Rules, which areposted as a Weibo community announcement. We have also provided an option for our usersto adjust the algorithm-driven recommendations settings for content and advertisements. A usercan click to deactivate “personalized ads recommendation” function to lower the relevancy ofthe ads pushed to this user, and to deactivate “personalized content recommendation” functionto lower relevancy of the content recommended to this user. We have been advised by our PRCLegal Adviser that our current approaches are in compliance with effective laws andregulations for algorithm recommendation in all material aspects as of the date of thisdocument, however, since this draft has not been enacted as of the date of this document, thepotential impact on our business operations is still substantially uncertain and the PRCregulatory authorities could take a contrary view over our current efforts as described above.During the Track Record Period, we generated approximately 55% to 65% of our advertisingand marketing revenues from the provision of promoted marketing products, which however,included advertisements that are not targeting advertising using algorithm recommendationengine and reach users universally. Furthermore, multiple factors, such as the content quality,product strategy, and algorithm technology, are inextricably intertwined in contributing to therevenue of our advertisement products, among which attribution from algorithmrecommendation is only one factor. If the draft is enacted as proposed, the impact on our SIGrecommendation engine still depends largely on the number of users who actually turn off ouralgorithm recommendation services. If such opt-out ratio turns out to be on the high end, theadvertisement efficiency on our platform may ultimately be lowered and our businessoperations may be adversely affected.

On September 17, 2021, the CAC, together with eight other governmental authorities, jointlyissued the Guidelines on Strengthening the Comprehensive Regulation of Algorithm forInternet Information Services (關於加強互聯網信息服務算法綜合治理的指導意見), whichprovides that daily monitoring of data use, application scenarios and effects of algorithms shallbe carried out by the relevant regulators, and security assessments of algorithm shall beconducted by the relevant regulators. The guidelines also provide that an algorithm filingsystem shall be established and classified security management of algorithms shall bepromoted. The Company will closely monitor the regulatory development and adjust itsbusiness operation from time to time to comply with the regulations over algorithm.

On August 30, 2021, the NPPA issued the Notice on Further Strict Management to PreventMinors from Indulging in Online Games (《關於進一步嚴格管理切實防止未成年人沉迷網絡遊戲的通知》), which requires all online game operators to provide services to minors only onany Friday, Saturday, Sunday and statutory holidays from 8:00 p.m. to 9:00 p.m., i.e. for onehour, and not to provide online games in any form to users who have not registered or loggedin with their real names. In addition to the real-name registration system already in place, wehave adjusted the systems in the games operated by us to comply with the requirements underthis notice. The revenue contributed by online games accounted for an insignificant portion ofour total revenue during the Track Record Period. We are of the view that this notice will nothave a material adverse impact on our business operation or financial results.

The Cyberspace Administration of China launched a “Fan Group Chaos Rectification” specialaction on June 15, 2021, followed by the issuance of the Notice on Further Strengthening theManagement of Chaos in Fan Groups (《關於進一步加強“飯圈”亂象治理的通知》) on August25, 2021.

groups for celebrities, specifically, in features such as celebrity rankings, hot topics, fancommunities, and fans interactive functions, so as to curb verbal abuse, stigmatization,instigation, confrontation, insults, slander, rumors, malicious marketing and the spread of otherharmful information. This notice requested, among other things, the cancellation of allrankings of celebrities. The rankings of music, film and television works are still allowed, butthe network platforms should optimize and adjust ranking rules to focus on the art worksthemselves and professional evaluation. Furthermore, minors are not allowed to make virtualgifting or spending money on supporting idols, or act as the organizer or manager of a fangroup. As of the Latest Practicable Date, we have taken measures specified in this notice to theextent applicable to our business, including removing the function of star power list on ourplatform.

On August 20, 2021, the SCNPC promulgated the Personal Information Protection Law of thePeople’s Republic of China (《中華人民共和國個人信息保護法》) (the “Personal InformationProtection Law”), effective from November 1, 2021. The Personal Information Protection Lawrequires, among others, that (i) the processing of personal information should have a clear andreasonable purpose which should be directly related to the processing purpose, in a method thathas the least impact on personal rights and interests, and (ii) the collection of personalinformation should be limited to the minimum scope necessary to achieve the processingpurpose to avoid the excessive collection of personal information. Different types of personalinformation and personal information processing will be subject to various rules on consent,transfer, and security. Entities handling personal information shall bear responsibilities fortheir personal information handling activities, and adopt necessary measures to safeguard thesecurity of the personal information they handle. Otherwise, the entities handling personalinformation could be ordered to correct, or suspend or terminate the provision of services, andface confiscation of illegal income, fines or other penalties. As of the date of this document,we were not involved in any enquiry, review or investigations by the CAC or other regulatoryauthorities in respect of the Personal Information Protection Law. However, we have beenadvised by our PRC Legal Adviser that this law is relatively new, and therefore there aresubstantial uncertainties with respect to its interpretation and implementation. See “RiskFactors — Privacy concerns relating to our products and services and the use of userinformation could damage our reputation, deter current and potential users and customers fromusing Weibo and negatively impact our business.”

On July 6, 2021, the General Office of the Central Committee of the Communist Party of Chinaand the General Office of the State Council jointly issued the Opinions on Strictly CombatingIllegal Securities Activities (《關於依法從嚴打擊證券違法活動的意見》), which emphasizeon the prevention of illegal securities activities and tightened supervision over overseas listingsby China-based companies. The opinions aim to achieve this by establishing a regulatorysystem and revising the existing rules for overseas listings by Chinese entities and affiliates,including potential extraterritorial application of China’s securities laws. As the opinions arenew, official guidance and implementation rules have not been issued and the finalinterpretation of and potential impact from these opinions remain unclear at this stage. See“Risk Factors — The approval of the CSRC or other PRC government authorities may berequired in connection with this offering under PRC law, and, if required, we cannot predictwhether we will be able to obtain such approval.” As of the date of this document, we have notreceived any inquiry, notice, warning, or sanction regarding this offering from the CSRC or anyother PRC government authorities.

On October 26, 2021, the CAC issued draft Administrative Provisions on the Account Namesof Internet Users (互聯網用戶賬號名稱信息管理規定(徵求意見稿)), revising the Regulationson the Administration of Internet User Account Names (互聯網用戶賬號名稱管理規定). Thisdraft requires Internet user account service platforms to, among others, establish, improve and

strictly implement account name information management system, information contentsecurity system, and personal information protection system, and establish an account nameinformation dynamic check patrol system for the verification of real identity information. Asof the date of this document, this draft has not been formally adopted. Substantial uncertaintiesexist with respect to its enactment timetable, final content, interpretation and implementation.We are still in the process of evaluating the effect of the requirements under this draft on ourbusiness and will make necessary adjustments to our business to comply with the applicablerequirements. If such draft is enacted as proposed, it would be costly for us to make moreefforts on monitoring and managing user account names to comply with these requirements.

On October 8, 2021, the National Development and Reform Commission issued a discussiondraft of the Negative List for Market Access (2021 Version) (市場准入負面清單(2021年版)),which provides that, among others, non-state-capitalized entities shall not conduct the businessof news collecting, editing, releasing and reporting. Weibo does not collect, edit, release orreport news by itself. Weibo holds an Internet News and Information Service License, whichallows it to provide the service of reposting news information and operating a platform todisseminate news information. The draft Negative List also provides that non-state-capitalizedentities shall not engage in live streaming of political, economic, military, diplomatic, majorsocial, cultural, scientific and technological, health, education, sports and other activities andevents related to political direction, public opinion orientation and value orientation. The scopeof live streaming business under this list is relatively broad and vague, and is subject to furtherclarifications and interpretations by the regulator. However, as we generated less than 5% ofour net revenues from live streaming, we do not believe this new requirement would have amaterial adverse impact on our business operations or financial results. As of the date of thisdocument, this draft has not been formally adopted. Substantial uncertainties exist with respectto its enactment timetable, final content, interpretation and implementation. If this draft isenacted as proposed, we may need to further adjust our business and operations, which may beadversely affected.

PRC Legal Opinion

Based on the foregoing and the currently effective PRC laws, we and our PRC Legal Adviserare of the view that the above recent changes in PRC laws and regulations will not affect ourcompliance with laws and regulations in any material aspects as of the date of this document.As of the date of this document, except as disclosed above, we were not involved in anyenquiry, review or investigations by the CAC or other authorities in respect of the aboverecently promulgated laws and regulations.

However, we and PRC Legal Adviser cannot preclude the possibilities that new rules orregulations promulgated in the future will impose additional compliance requirements on us.PRC regulations may change from time to time which may influence our business operationand operation results. Our efforts to comply with new and changing laws are likely to resultin increased costs and risks of non-compliance. See “Risk Factors – We are subject to changinglaws and regulations regarding regulatory matters, corporate governance and public disclosurethat have increased both our costs and the risk of non-compliance.”

FORWARD-LOOKING STATEMENTS

– 45 –

You should carefully consider all of the information set out in this document beforemaking an investment in the Shares, including the risks and uncertainties described belowin respect of our business and our industry and the Global Offering. You should payparticular attention to the fact that we are a company incorporated in the Cayman Islandsand that our principal operations are conducted in China and are governed by a legal andregulatory environment that in some respects differs from what prevails in othercountries. Our business could be affected materially and adversely by any of these risks.

RISKS RELATING TO OUR BUSINESS

If we fail to grow our active user base, or if user engagement on our platform declines, ourbusiness, financial condition and operating results may be materially and adverselyaffected.

The growth of our active user base and the level of user engagement are critical to our business.We had 566 million MAUs and 246 million average DAUs in June 2021. Our business has beenand will continue to be significantly affected by our success in growing and retaining massiveactive users and increasing their overall level of engagement on our platform, including theirengagement with promoted feeds, other advertising and marketing products and value-addedservices on our platform. We anticipate that our user growth rate will slow over time as the sizeof our user base increases and as we achieve higher market penetration in China’s internetpopulation. To the extent our user growth rate slows or the number of our users declines, oursuccess will become increasingly dependent on our ability to retain existing users and enhanceuser activities and stickiness on the platform. If people do not perceive content and otherproducts and services on our platform to be interesting and useful, we may not be able to retainand attract users or increase their engagement. A number of user-oriented websites and mobileapplications that achieved early popularity have since seen their user bases or levels ofengagement decline, in some cases precipitously. There is no guarantee that we will notexperience a similar erosion of our active user base or engagement level. A number of factorscould potentially negatively affect user growth and engagement, including if:

• we are unable to retain existing users and attract new users to our platform, orachieve greater penetration into lower tier cities in China;

• there is a decrease in the perceived quality or reliability of the content generated byour users;

• a large number of influencers, such as celebrities, key opinion leaders, or KOLs andother public figures, and platform partners, such as media outlets and organizationswith media rights, switch to alternative platforms or use other products and servicesmore frequently;

• we are unable to manage and prioritize information to ensure users are presentedwith content that is appropriate, interesting, useful and relevant;

• we fail to introduce new and improved products or services or we introduce new orimproved products or services that are not well received by users;

• technical or other problems prevent us from delivering our products or services ina rapid and reliable manner or otherwise adversely affect the user experience;

RISK FACTORS

– 46 –

• users believe that their experience is diminished as a result of the decisions we makewith respect to the frequency, relevance, prominence, format and quality of theadvertisements displayed on our platform;

• we are unable to combat spam or other hostile or inappropriate usage on ourplatform;

• there are user concerns related to privacy and communication, safety, security orother factors;

• we fail to provide adequate customer service to our users;

• users engage with other platforms or activities instead of ours;

• there are adverse changes in our products or services that are mandated by, or thatwe elect to make to address, legislation, regulations or government policies; or

• we fail to maintain our brand image or our reputation is damaged.

We have undertaken various initiatives to stimulate the growth of our users and userengagement. For instance, in addition to the microblogging service with which Weibooriginally started, we have added functionalities such as trends, topics, search, short videos,live streaming and interest-based information feeds over the years, which we believe havehelped broaden our appeal and generate more user traffic and engagement. However, there canbe no assurance that these and other strategies will continue to be effective. If we are unableto increase our user base and user engagement, our platform could be less attractive to potentialnew and existing users and customers, which would have a material and adverse impact on ourbusiness, financial condition and operating results.

If our users and platform partners do not continue to contribute content or theircontributions are not valuable to other users, we may experience a decline in user trafficand user engagement.

Our success depends on our ability to provide users with interesting and useful content, whichin turn depends on the content contributed by our users and platform partners. We believe thatone of our competitive advantages is the quality, quantity and open nature of the content onWeibo, and that access to rich content is one of the main reasons users visit Weibo. We seekto foster a broader and more engaged user community, and we encourage influencers, such ascelebrities, KOLs and other public figures, and platform partners, such as multi-channelnetworks, (the “MCNs”), media outlets and organizations with media rights, to use ourplatform to express their views and share interesting, and high quality content.

Among all our users, influencers have been contributing increasingly interesting and attractivecontents on our platform. We provide these content creators with the opportunity to monetizetheir social assets on Weibo through advertising, e-commerce, paid-subscription, tipping andother means. If content creators do not see significant value from their social marketingactivities on Weibo and find monetization on Weibo inadequate, we may have to subsidize themthrough direct content cost payout, which may have an adverse and material impact on ourbusiness and operating results. Alternatively, content creators may choose to switch to otherplatforms and contribute less or no content to Weibo, which may cause our user base and userengagement to decline and our customers view our products and services less attractive foradvertising and marketing purposes and consequently reduce their advertising spending on ourplatform.

RISK FACTORS

– 47 –

If users and platform partners do not continue to contribute content to Weibo due to policychanges, their use of alternative communication channels or any other reasons, and we areunable to provide users with interesting, useful and timely content, our user base and userengagement may decline. If we experience a decline in the number of users or the level of userengagement, customers may not view our products and services as attractive for theiradvertising and marketing expenditures and may reduce their spending with us, which wouldmaterially harm our business and operating results.

We rely on our partnership program with channel partners, which mainly includeapplication pre-install partners, programmatic buying partners and applicationmarketplaces, to drive traffic to our platform, and if our partnership program becomesless effective or if the smartphone market and shipment in China slow down compared tothe prior years, traffic to our platform could decline and our business and operatingresults could be adversely affected.

We work with application (app) pre-install partners, such as key domestic handsetmanufacturers for user acquisition and activation. Due to intense competition in themarketplace, app pre-install partners may raise prices to a point where it becomes costprohibitive for us to rely on them for Weibo user activation, or they may decide to discontinuetheir services to us altogether. The partnership also highly depends on the total amount ofhandset shipment and sales of our partners, which may fluctuate or slow down compared withprior years. The smartphone shipment in China decreased in 2020, compared to 2019. Thegrowth of Weibo’s user base is impacted by the growth of new users from Weibo app, andpre-installation of Weibo app on new smartphones is an important source of new Weibo users.A continuing slowdown of new smartphone shipment in China may adversely impact thegrowth rate of our new users. If this trend continues, our business and operating results maybe materially and adversely affected.

We also work with programmatic buying partners, such as top applications for traffic directionand user activation. Due to the real time bidding nature of programmatic buying, the prices forinventories on top applications may fluctuate or surge to a point where it becomes less costeffective for us to invest in the channel. In addition, inaccurate user targeting and the possiblehigh churn rate observed during the traffic direction step may also limit the overalleffectiveness of the partnership.

In addition, we work with application marketplaces, including app stores of key domestichandset manufacturers as well as other major application marketplaces, such as Tencent AppStore, Baidu Mobile Assistant and 360 Mobile Assistant, to drive downloads of our mobileapplications. In the future, Google (Android), Apple or other operators of applicationmarketplaces may make changes to their marketplaces and make access to our products andservices more difficult.

If we are unable to compete effectively for user traffic or user engagement, our businessand operating results may be materially and adversely affected.

Competition for user traffic and user engagement is intense and we face strong competition inour business. Major Chinese internet companies, such as Tencent and Bytedance, competedirectly with us for user traffic and user engagement, content, talent and marketing resources.As a social media featuring social networking services and messenger features, we are subjectto intense competition from providers of similar services as well as potentially new types ofonline services. These services include (i) messengers and other social apps and sites, such asWeixin/WeChat, QQ Mobile, Qzone Mobile and Momo; (ii) news apps and sites, such as those

RISK FACTORS

– 48 –

operated by other major internet companies, including Tencent, Bytedance, Baidu, NetEase,Sohu and Phoenix News Media; (iii) multimedia apps (photo, video and live streaming, etc.),such as Douyin/TikTok, Kuaishou, Bilibili, iQiyi, Tencent Video, Youku, Xigua Video, Red(Xiaohongshu), Momo and JOYY. In addition, as a media platform in nature, we also competewith traditional media companies for audiences and content.

We also compete with both offline and online games for the time and money of gamers. Weoffer social commerce solutions to our customers that enable them to conduct e-commerce onour platform. Consequently, our offerings compete with e-commerce companies and onlineverticals that enable merchants to conduct e-commerce, including location-based services andonline-to-offline services. In addition to direct competition, we face indirect competition fromcompanies that sponsor or maintain high traffic volume websites or provide an initial point ofentry for internet users, including but not limited to providers of search services, web browserand navigation pages, such as Baidu, UC Web and Qihoo 360. We may also face competitionfrom global social media, social networking services and messengers, such as Facebook,Instagram, Twitter, Youtube, TikTok, WhatsApp, Facebook Messenger, Snapchat, Pinterest,Line and Kakao Talk. Some of our competitors may have substantially more cash, traffic,technical and other resources than we do. We may be unable to compete successfully againstthese competitors or new market entrants, which may adversely affect our business andfinancial performance.

We believe that our ability to compete effectively for user traffic and user engagement dependsupon many factors both within and beyond our control, including:

• the popularity, usefulness, ease of use, performance and reliability of our products andservices compared to those of our competitors;

• the amount, quality and timeliness of content aggregated on our platform;

• our ability to enable celebrities, KOLs, media outlets and other content creators to quicklyand efficiently build a fan base and monetize from their social assets;

• our ability, and the ability of our competitors, to develop new products and services andenhancements to existing products and services to keep up with user preferences anddemands;

• the frequency, relevance and relative prominence of the advertisements displayed by usor our competitors;

• our ability to establish and maintain relationships with platform partners;

• our ability to provide effective customer service and support;

• changes mandated by, or that we elect to make to address, legislation, regulations orgovernment policies, some of which may have a disproportionate effect on us;

• acquisitions or consolidation within our industry, which may result in more formidablecompetitors; and

• our reputation and brand strength relative to our competitors.

RISK FACTORS

– 49 –

We may not be able to maintain or grow our revenues or our business.

We have experienced significant growth in revenues and in our business in recent years. Ourability to continue to grow our revenues depends on a number of factors. See “FinancialInformation — Factors Affecting Our Results of Operations” for a detailed discussion.

Our revenue growth also depends on our ability to continue to grow our core businesses,newly-developed businesses, as well as businesses we have acquired or which we consolidated.We are exploring and will continue to explore in the future new business initiatives, includingin industries and markets in which we have limited or no experience, as well as new businessmodels, that may be untested. Developing new businesses, initiatives and models requiressignificant investments of time and resources, and may present new and difficult technological,operational and compliance challenges. Many of these challenges may be specific to businessareas with which we do not have sufficient experience. We may encounter difficulties orsetbacks in the execution of various growth strategies and these growth strategies may notgenerate the returns we expect within the timeframe we anticipate, or at all.

In addition, our overall or segment revenue growth may slow or our revenues may decline forother reasons, including increasing competition and slowing growth of China’s smartphonemarket, disruptions to China’s economy or the global economy from pandemics, naturaldisasters or other events, as well as changes in the geopolitical landscape, government policiesor general economic conditions. As our revenue grows to a higher base level, our revenuegrowth rate may slow in the future. Furthermore, due to the size and scale we have achieved,our user base may decrease, not continue to grow as quickly or at all.

We generate a substantial majority of our revenues from online advertising andmarketing services. If we fail to generate sustainable revenue and profit through ouradvertising and marketing services, our result of operations could be materially andadversely affected.

We started to generate revenues in 2012 through advertising and marketing services, and to aless extent also through value-added services. Ever since then, advertising and marketingservices have been contributing a substantial majority of our total revenues, accounting for88% of our revenues in 2020 and 86% of our revenues for the six months ended June 30, 2021.Therefore, any failure to continue generating sustainable revenue and profit through ouradvertising and marketing services could materially harm our business.

Compared with traditional advertising and marketing solutions, online advertising andmarketing services are evolving rapidly and sometimes considered experimental. In addition,we, as well as the whole industry, are endeavoring to develop novel forms of advertising andmarketing services. As a result, we cannot guarantee that the advertising and marketingstrategies we have adopted can generate sustainable revenues and profit. Particularly, as iscommon in the industry, our advertising and marketing customers do not have long-termcommitments with us. In addition, some potential new customers may view our advertising andmarketing services as unproven, and we may need to devote additional time and resources toconvince them. Customers will not continue to do business with us or may only be willing toadvertise with us at reduced prices if we do not deliver advertising and marketing services inan effective manner, or if they do not believe that their investment in advertising and marketingwith us will generate a competitive return relative to alternative advertising platforms.

RISK FACTORS

– 50 –

Our ability to add new customers and increase spending of existing customers can beparticularly affected by our ability to provide timely and reliable measurement analysis ofcustomers’ advertising campaigns on Weibo, as some customers, especially key accounts, relyon advertisement measurement to evaluate advertising effectiveness. We are working withthird-party measurement firms to provide these data services to our customers but the onlineadvertisement measurement market in China is nascent. We cannot assure you that ourmeasurement partners will be able to provide measurement to the satisfaction of our customers.If our customers are unable to obtain measurement results on their marketing campaigns onWeibo to their satisfaction, our customers may be less willing to maintain or expand theiradvertising spending on our platform, and our financial conditions, results of operations andprospects may be materially and adversely affected.

We also need to adapt our advertising and marketing service offerings to the way usersconsume contents on our platforms. We introduced mobile-adapted promoted marketingsolutions, such as promoted feeds, to our advertisers as our mobile products gain more usertraffic. Users’ preferences on content format are also evolving. Online content in video formathas become increasingly prevalent in recent years. If we are unable to adapt our products andservices for the video environment and develop products and services to generate videoadvertising revenues, especially for the mobile environment, our results of operations andprospects may be materially and adversely affected.

Advertisements shown on our platform may subject us to penalties and otheradministrative actions.

Under PRC advertising laws and regulations, we are obligated to monitor the advertisingcontent shown on our platform to ensure that such content is true and accurate and incompliance with applicable PRC laws and regulations. PRC advertising laws and regulationsimpose prohibitions and restrictions on certain types of advertisements. For instance,advertisements for certain products, such as tobacco, are not allowed to be publicly posted, andadvertisements for other products and services, such as alcohol, medical treatment,pharmaceuticals or medical devices, healthcare food, real estate and financial products, aresubject to certain restrictions on content and other requirements. In addition, where a reviewby relevant governmental authorities is required before certain types of advertisements can beposted, such as advertisements for pharmaceuticals and medical devices, we are obligated toconfirm that such review has been performed and approval has been obtained.

The Chinese government may from time to time promulgate new advertising laws andregulations, including possible additional restrictions on online advertising services, and theserestrictions may relate to, among other attributes, the content, placement and appearance ofadvertisements. In addition, recent activities and technology trends in advertising, such as linksin comments or posts, and the proliferation of short video and live streaming platforms, withpaid promotions that are frequently not marked as advertising, have made advertising contentmonitoring more challenging. Moreover, technologies and tools attempting to circumvent,evade or deceive our advertisement content monitoring system are evolving, which makes itmore complicated for us to monitor and review the advertisements on our platform. When wediscover advertisements that violate laws and regulations, we will timely take correspondingmeasures. Although we have made significant efforts to ensure that the advertisements shownon our platform are in full compliance with applicable PRC laws and regulations, we cannotensure that we will be in compliance at all times with the requirements under any new laws andregulations. For a detailed description of the procedures we implement, see “Business — RiskManagement and Internal Control — Internal Control Risk Management.” Failure to complywith these obligations may subject us to fines and other administrative penalties.

If advertisements shown on our platform are in violation of relevant PRC advertising laws andregulations, we may be subject to penalties, including fines, confiscation of advertisingincome, orders to cease dissemination of the advertisements and orders to publish correctiveinformation. In case of serious violation, the PRC governmental authorities may revoke ourbusiness licenses. During the Track Record Period, our Major Subsidiaries have received threepenalties, including fines from RMB1,000 to RMB200,000, and confiscation of advertisingincome. For example, in 2018, Beijing Haidian Administration for Industry and Commerceissued a decisions to impose an administrative penalty on Weimeng, including a fine ofRMB200,000 on Weibo and confiscation of the advertising revenue of RMB1,171.19, becausethe authorities was of the opinion that certain advertisements published on Weibo containedcontent that violated “good social customs.” We paid the fine and cooperated with the relevantgovernment authorities to take corrective measures as required. We believe these penalties,individually or in the aggregate, did not have a material adverse effect on our business,financial condition or results of operations during the Track Record Period. However, there canbe no assurance that there will not be any further penalties, which may have a material andadverse effect on our business, financial condition, results of operations and prospects, brandand reputation.

If we are unable to compete effectively for advertising and marketing spending, ourbusiness and operating results may be materially and adversely affected.

In addition to intense competition for users and user engagement, we also face significantcompetition for advertising and marketing spending. A substantial majority of our revenues arecurrently generated through advertising and marketing services. We compete against online andmobile businesses that offer such services, mainly including Tencent, Bytedance, Baidu,Kuaishou, iQiyi, NetEase and Sohu. We also compete with internet companies that offeronline-to-offline (O2O), purchase solutions and other performance-based advertising andmarketing services and digital media tailored to specific vertical industries including fastmoving consumer goods, IT, automobile, e-commerce, entertainment and travel, such asMeituan, Autohome, Bitauto and Qutoutiao. We also compete against traditional media outlets,such as television, radio and print, for advertising and marketing budgets.

In order to grow our revenues and improve our operating results, we must increase our marketshare of advertising and marketing spending relative to our competitors, many of which arelarger companies that offer more traditional and widely accepted advertising products. Inaddition, some of our larger competitors have substantially broader product or service offeringsand leverage their relationships based on other products or services to gain additional share ofadvertising and marketing budgets.

We believe that our ability to compete effectively for advertising and marketing spendingdepends upon many factors both within and beyond our control, including:

• the size, composition and activeness of our user base relative to those of our competitors;

• the breadth, innovation and effectiveness of our product and service offerings;

• the timing and market acceptance of our advertising and marketing products and services,including breadth, quality and variety of our advertisement formats and features and thoseof our competitors;

• the effectiveness of our advertisement targeting capabilities, and those of our competitors;

RISK FACTORS

– 52 –

• the volume, pricing and return on investment of our products and services relative tothose of our competitors;

• the reach, engagement and effectiveness of our advertising and marketing products andservices relative to those of our competitors;

• the availability, accuracy and utility of analytics and measurement solutions offered by usor our partners relative to those of our competitors;

• our ability to attract, retain and motivate talented employees;

• the effectiveness of our performance-based advertisements and real-time bidding systemrelative to those of our competitors;

• our sales and marketing efforts, and those of our competitors; and

• our reputation and the strength of our brand relative to our competitors.

Significant acquisitions and consolidation by and among our actual and potential competitorsmay present heightened competitive challenges for our business. Acquisitions of our platformpartners by our competitors could result in reduced content and functionality of our productsand services. Consolidation may also enable our larger competitors to offer bundled orintegrated products that feature alternatives to our platform. Reduced content and functionalityof our products and services, or our competitors’ ability to offer bundled or integrated productsthat compete directly with us, may cause our user base and user engagement to decline andcustomers to reduce their spending with us. If we are not able to compete effectively foradvertising and marketing spending, our business and operating results may be materially andadversely affected.

Our operating history may not be the indicator of our future prospects.

The market for social media is still evolving and may not develop as expected. People who arenot our users, customers or platform partners may not understand the value of our products andservices and new users, customers or platform partners may initially find our products andservices confusing. There may be a perception that our products and services are only usefulto users who post, or to influential users with large audiences. Convincing potential new users,customers and platform partners of the value of our products and services is critical toincreasing the number of our users, customers and platform partners and to the success of ourbusiness. Although we have experienced continued user growth as shown by the increase of ourMAUs and DAUs for the past few years, some of our peers may have experienced a declinein user base. If microblogging, social media, online media or social product, in general,declines in popularity among Chinese internet users, we may be unable to grow our user baseor maintain or increase user engagement.

We launched Weibo in August 2009 and began to generate revenues in 2012. Given the rapidlyevolving markets in which we compete, our historical operating results may not be useful toyou in predicting our future operating results. You should consider our business and prospectsin light of the risks and challenges we encounter or may encounter in this developing andrapidly evolving market. These risks and challenges include our ability to, among other things:

• increase the number of our users and the level of user engagement;

RISK FACTORS

– 53 –

• develop a reliable, scalable, secure, high-performance technology infrastructure that canefficiently handle increased usage;

• convince customers of the benefits and effectiveness of our advertising and marketingservices;

• refine our interest-based recommendation engine to enable more relevant contentrecommendation and effective audience targeting;

• increase demand for value-added services, such as VIP membership, live streaming, andgame-related services;

• develop and deploy new features, products and services for our users, customers andplatform partners, including video functionalities and interest-based information feeds;

• successfully compete with other companies, some of which have substantially greaterresources and market power than us, that are currently in, or may in the future enter, ourindustry, or duplicate the features of our products and services;

• attract, retain and motivate talented employees;

• process, store, protect and use personal data in compliance with governmentalregulations, contractual obligations and other obligations related to privacy and security;and

• defend ourselves against litigation, regulatory, intellectual property, privacy or otherclaims.

If we fail to educate potential users, customers and platform partners about the value of ourproducts and services, if the market for our platform does not develop as we expect or if wefail to address the needs of this market, our business will be harmed. Failure to adequatelyaddress these or other risks and challenges could harm our business and cause our operatingresults to suffer.

Alibaba is our largest customer and an important strategic partner. If we fail to maintainour collaboration with Alibaba, our results of operations and growth prospect may beadversely and materially affected.

From April 2013 to January 2016, we had a strategic collaboration with Alibaba and itsaffiliated entities to jointly explore social commerce and develop innovative marketingsolutions to enable merchants on Alibaba’s e-commerce platforms to better connect and buildrelationships with our users. Revenues generated from the strategic collaboration with Alibabaaccounted for 30% of our revenues from 2013 to 2015. Although revenue contribution byAlibaba has declined as a percentage to our total revenues in recent years, as a result of therapid growth of our business scale as well as our strategy to diversify revenue sources after thestrategic collaboration agreement expired in early 2016, Alibaba remains as our largestcustomer. More importantly, we rely on them to enable us to offer e-commerce advertisingsolutions to brands and merchants on both of our platforms. If we are unable to either maintainstrong cooperation with Alibaba or find other customers that can bring in similar amount ofrevenues to offset the possible decline of revenue from Alibaba or the revenue associated withAlibaba’s ecosystem, our results of operations and growth prospects may be adversely andmaterially affected.

RISK FACTORS

Our future performance depends in part on support from our platform partners,particularly copyright content providers and MCNs.

Although most of the content on our platform come from individual users, platform partnershave become an increasingly important source of high-quality content. We believe userengagement with our products and services depends in part on the quality of applications andcontent generated by our platform partners, particularly copyright content providers and theMCNs. Copyright content providers have traditionally been an important source of premiumcontent on our platform. Meanwhile, as content on our platform expands into various newformats, such as short videos, the role of MCNs as talent agencies for professional contentcreators is becoming increasingly important. We have built a large network of MCNs indifferent domains, such as video and e-commerce, and we rely on these platform partners toincubate and grow content creators so that they share more quality content on Weibo. If we areunable to enjoy continued collaboration with copyright content providers and expand ournetwork of MCNs and incentivize them to share more content, our content offerings may notbe as robust and competitive and our user base and user engagement may be adversely andmaterially affected.

We also work closely with third-party developers to build Weibo-integrated applications toenhance Weibo’s functionalities. Such existing and prospective developers may not besuccessful in building, growing, or monetizing mobile and/or web applications that create,maintain and enhance user engagement. Additionally, developers may choose to build on otherplatforms rather to integrate with Weibo. We are continuously seeking to balance thedistribution objectives of our developers with our desire to provide an optimal user experience,and we may not be successful in achieving a balance that continues to attract and retain suchdevelopers. If we are not successful in our efforts to continue to grow the number of developersthat choose to build products that integrate with Weibo or if we are unable to continue to buildand maintain good relationships with such developers, our user growth and user engagementand our financial results may be adversely and materially affected.

Our new products, services and initiatives and changes to existing products, services andinitiatives could fail to attract users and customers or generate revenues.

Our ability to increase the size and engagement of our user base, attract customers and generaterevenues will depend in part on our ability to successfully launch new products and services.We may introduce significant changes to our existing products and services or develop andintroduce new products and services, including technologies with which we have little or noprior development or operating experience. If new or enhanced products or services fail toengage users, customers and platform partners, we may fail to attract or retain users or togenerate sufficient revenues to justify our investments, and our business and operating resultscould be adversely affected. In addition, we may launch strategic initiatives that do not directlygenerate revenues but which we believe will enhance our attractiveness to users, customers andplatform partners. We may not be successful in future efforts to generate revenues from ournew products or services. If our strategic initiatives do not enhance our ability to monetize ourexisting products and services or enable us to develop new approaches to monetization, we maynot be able to maintain or grow our revenues or recover any associated development costs andour operating results may be adversely affected.

RISK FACTORS

If we fail to effectively manage our growth, our business and operating results could beharmed.

We operate our business in a rapidly evolving industry and highly competitive market, whichwill continue to place significant demands on our management, operational and financialresources to sustainably grow our business. We may encounter difficulties as we establish andexpand our operations, product development, sales and marketing, and general andadministrative capabilities. We face significant competition for talented employees from otherhigh-growth companies, which include both publicly traded and privately held companies, andwe may not be able to hire new employees quickly enough to meet our needs. To attract highlyskilled personnel, we have had to offer, and believe we will need to continue to offer,competitive compensation packages. As we continue to grow, we are subject to the risks ofover-hiring, over-compensating our employees and over-expanding our operatinginfrastructure, and to the challenges of integrating, developing and motivating a growingemployee base. In addition, we may not be able to innovate or execute as quickly as a smallerand more efficient organization. If we fail to effectively manage our hiring needs andsuccessfully integrate our new hires, our efficiency and ability to meet our forecasts and ouremployee morale, productivity and retention could suffer, and our business and operatingresults could be adversely affected.

As we strive to broaden our user base, increase user engagement, and develop new features andproducts, we often have to proactively devote significant resources to accommodate futuregrowth and to meet market demand. If market condition changes or we misjudged futuredemand, however, we may incur high costs and expenses relative to our return, which couldnegatively affect our operating results. In addition, copyright content is costly and thecompetition for it is fierce. Mismanagement of copyright content purchase and usage, such asfocus on content that turn out to be less popular or loss of valuable copyright content tocompetitors, may lead to a disproportional increase in expenses and adversely affect ourbusiness.

Continued growth could also strain our ability to maintain reliable service levels for our usersand customers, develop and improve our operational, financial, legal and management controls,and enhance our reporting systems and procedures. Our expenses may grow faster than ourrevenues, and our expenses may be greater than what we anticipate. Managing our growth willrequire significant expenditures and allocation of valuable management resources. If we fail toachieve the necessary level of efficiency in our organization as it grows, our business,operating results and financial condition could be harmed.

Our operating results may fluctuate from quarter to quarter, which makes it difficult topredict.

Our quarterly operating results have fluctuated in the past and will fluctuate in the future. Asa result, our past quarterly operating results are not necessarily indicators of futureperformance. Our operating results in any given quarter can be influenced by numerous factors,many of which we are unable to predict or are outside of our control, including:

• our ability to grow our user base and user engagement;

• fluctuations in spending by our advertising and marketing customers, including as a resultof seasonality, major events and extraordinary news events, pandemics or other factors;

• our ability to attract and retain advertising and marketing customers;

RISK FACTORS

– 56 –

• the occurrence of planned or unplanned significant events, including events that maycause substantial stock-based compensation or other charges;

• the development and introduction of new products or services or changes in features ofexisting products or services;

• the impact of competitors or competitive products and services;

• the pricing of our products and services;

• our ability to maintain or increase revenues;

• our ability to maintain or improve gross margins, operating margins and net margins;

• increases in our costs and expenses that we may incur to grow and expand our operationsand to remain competitive;

• system failure or outages, which could prevent us from displaying advertisements for anyperiod of time;

• changes in U.S. GAAP and the related policies, guidance or interpretations;

• changes in the legal or regulatory environment or proceedings, including with respect tosecurity, privacy or enforcement by government regulators, including fines, orders orconsent decrees; and

• changes in Chinese or global business or macroeconomic conditions.

Given our limited operating history and the rapidly evolving market in which we compete, ourhistorical operating results may not be useful to you in predicting our future operating results.Our limited operating history and our rapid growth make it difficult for us to identify recurringseasonal trends in our business. The advertising industry in China experiences seasonality.Historically, advertising spending tends to be the lowest in the first quarter of each calendaryear due to long holidays around the Lunar New Year, and we believe that this seasonalityaffects our quarterly results. In addition, economic concerns continue to create uncertainty andunpredictability and add risk to our future outlook. An economic downturn in China or globallycould cause our advertising and marketing customers to reduce their advertising budgets, andresult in other adverse effects that could harm our operating results. Other factors that maycause our operating results to fluctuate include popular sports events, such as the FIFA WorldCup and the Olympic Games. Due to our rapid growth and limited operating history, theseasonal trends that we have experienced in the past may not apply to, or be indicative of, ourfuture operating results.

Spam could diminish the user experience on our platform, which could damage ourreputation and deter our current and potential users from using our products andservices.

“Spam” on Weibo refers to a range of abusive activities that are prohibited by our terms ofservice and is generally defined as unsolicited actions that negatively impact other users withthe general goal of drawing user attention to a given account, site, product or idea. Thisincludes posting large numbers of unsolicited mentions of a user, duplicate feeds, misleadinglinks (e.g., to malware or click-jacking pages) or other false or misleading content, andaggressively following and un-following accounts, sending unsolicited invitations, reposting

RISK FACTORS

feeds and favoring feeds to inappropriately attract attention. Our terms of service also prohibitthe creation of serial or bulk accounts, both manually or using automation, for disruptive orabusive purposes, such as to post spam or to artificially inflate the popularity of users seekingto promote themselves on Weibo. Although we continue to invest resources in reducing spamon Weibo, we expect spammers will continue to seek ways to act inappropriately on ourplatform. In addition, we expect that increases in the number of users on our platform willresult in increased efforts by spammers to misuse our platform. We continuously combat spam,including by suspending or terminating accounts we believe to be spammers and launchingalgorithmic changes focused on curbing abusive activities. Our actions to combat spam requirethe diversion of significant time and focus of our engineering team from improving ourproducts and services. If we are unable to effectively manage and reduce spam on Weibo, ourreputation for delivering relevant content could be damaged, user engagement could declineand our operational costs could increase.

We are subject to changing laws and regulations regarding regulatory matters, corporategovernance and public disclosure that have increased both our costs and the risk ofnon-compliance.

We are subject to rules and regulations by various governing bodies, including, for example,the Securities and Exchange Commission, which is charged with the protection of investors andthe oversight of companies whose securities are publicly traded, and the various regulatoryauthorities in China and the Cayman Islands, and to new and evolving regulatory measuresunder applicable law. Our efforts to comply with new and changing laws and regulations haveresulted in and are likely to continue to result in, increased general and administrative expensesand a diversion of management time and attention from revenue-generating activities tocompliance activities.

Moreover, because these laws, regulations and standards are subject to varying interpretations,their application in practice may evolve over time as new guidance becomes available. Thisevolution may result in continuing uncertainty regarding compliance matters and additionalcosts necessitated by ongoing revisions to our disclosure and governance practices. If we failto address and comply with these regulations and any subsequent changes, we may be subjectto penalty and our business may be harmed.

Privacy concerns relating to our products and services and the use of user informationcould damage our reputation, deter current and potential users and customers from usingWeibo and negatively impact our business.

We collect personal data from our users in order to better understand our users and their needsand to help our customers target specific demographic groups. Concerns about the collection,use, disclosure or security of personal information or other privacy-related matters, even ifunfounded, could damage our reputation, cause us to lose users and customers and adverselyaffect our operating results. While we strive to comply with applicable data protection laws andregulations, as well as our own posted privacy policies and other obligations we may have withrespect to privacy and data protection, the failure or perceived failure to comply may result,and in some cases has resulted, in inquiries and other proceedings or actions against us bygovernment agencies or others, as well as negative publicity and damage to our reputation andbrand, each of which could cause us to lose users and customers, which could have an adverseeffect on our business.

RISK FACTORS

– 58 –

Any systems failure or compromise of our security that results in the unauthorized access toor release of our users’ or customers’ data could significantly limit the adoption of our productsand services, as well as harm our reputation and brand and, therefore, our business. We strictlylimit third-party developers’ access to user privacy and user data, and we expend significantresources on technology and product development to protect against leakage of userinformation and other security breaches. Nonetheless, given its great commercial value, ouruser data may still be misused by third-parties, which could expose us to legal and regulatoryrisks and seriously harm our business.

The PRC regulatory and enforcement regime with regard to data security and data protectionis evolving. The PRC Civil Code (《中華人民共和國民法典》), the PRC Cyber Security Law(《中華人民共和國網絡安全法》), the Personal Information Protection Law (《個人信息保護法》) and the PRC Data Security Law (《數據安全法》) protect individual privacy andpersonal data security in general by requiring internet service providers to collect data inaccordance with the laws and in proper manner, and obtain consents from internet users priorto the collection, use or disclosure of internet users’ personal data. See “Regulatory Overview— Regulations on Information Security” and “Regulatory Overview — Regulations on InternetPrivacy.” In addition, the Cyber Security Law sets high requirements for the operationalsecurity of facilities deemed to be part of China’s “critical information infrastructure.” See“Risk Factors — Risks Relating to Doing Business in the People’s Republic of China —Substantial uncertainties exist with respect to the interpretation and implementation ofcybersecurity related regulations and cybersecurity review as well as any impact these mayhave on our business operations.” We have been advised by our PRC Legal Adviser that theselaws and regulations are relatively new, and therefore there are substantial uncertainties withrespect to the interpretation and implementation of these data security laws and regulations.Weibo may need to adjust its business to comply with data security requirements from time totime. Weibo has taken measures to comply with existing laws and regulations, see “Business— Risk Management and Internal Control — Data and technology system risk management.”

Furthermore, if privacy concerns or regulatory restrictions prevent us from sellingdemographically targeted advertising, we may become less attractive to our customers. In HongKong, however, the Personal Data (Privacy) Ordinance provides that an internet company maynot collect information about its users, analyze the information for a profile of the user’sinterests and sell or transmit the profiles to third parties for direct marketing purposes withoutthe user’s consent. In the European Union, or EU, the General Data Protection Regulation, orGDPR, which came into effect on May 25, 2018, present increased challenges and risks inrelation to policies and procedures relating to data collection, storage, transfer, disclosure,protection and privacy, and will impose significant penalties for non-compliance, including forexample, penalties calculated as a percentage of global revenue under the GDPR. The potentialrisks associated with non-compliance therewith are difficult to predict. Other jurisdictions mayhave similar prohibitions. Although less than 1% of our revenues in 2020 are generated in HongKong, EU and other jurisdictions with similar prohibitions, we hope to attract more users inthese jurisdictions and if we are unable to construct demographic profiles of internet usersbecause they refuse to give consent, we will be less attractive to customers and our businesscould suffer.

RISK FACTORS

– 59 –

In addition to the possibility of fines, enforcement actions can result in orders requiring us tochange our practices, which could have an adverse effect on our business and operating results.In March 2020, we experienced a data leakage caused by malicious queries by users throughour application programming interface, for which the Ministry of Industry and InformationTechnology, or the MIIT summoned our representatives to a meeting on March 21, 2020 andinstructed us to take steps to improve data security in accordance with the applicableregulations, including improving our privacy policy, strengthening user information protectionand internal data security management, and other measures. We immediately took measures inresponse to this incident, including upgrading our security interface.

Since January 2019, in order to better implement the PRC Cyber Security Law (《網絡安全法》and the PRC Law for the Protection of Consumer Rights and Interests (《消費者權益保護法》), relevant PRC government departments jointly launched nationwide specialrectification programs on the illegal collection and use of personal information by mobile appseach year. In the 2020 Special Rectification Program, launched on July 22, 2020 by thecyberspace Administration of China, the MIIT, the Ministry of Public Security, and the StateAdministration for Market Regulation, and focusing on identifying and rectifying conducts ofvarious apps in illegal collection of personal facial features and other biometric information,unauthorized recording of users’ voice or access of users’ photos, and unauthorized uploadingof personal information, Weibo was identified by the authorities as having misled users toagree to the collection of personal information and failed to list out the purpose and type ofpersonal information collected by certain software development kits on its platforms inNovember 2020. Weibo took actions in response to the identified issues and completed therectification as required. On July 23, 2021, MIIT launched the 2021 Special RectificationProgram aiming at rectifying disruption of market order, infringement on users’ rights andinterests, threaten on data security, and violation of relevant regulations on qualifications andresources management by the internet companies, for which Weibo, together with 24 othermajor internet companies, attended a meeting about the 2021 Special Rectification Program onInternet Industry held by the MIIT on July 30, 2021, to discuss and receive instructionsregarding self-examination and self-rectification under the Special Rectification Program. Therectification procedures generally include three steps: first, our company to conduct aself-examination and self-rectification and deliver a report to the relevant governmentauthority for review; second, the government authority to provide comments on the report andguidance for our company to achieve compliance with the relevant PRC laws and regulations;and third, the government will make an inspection and confirm the rectification results. Weibohas initiated a self-examination and self-rectification and submitted the report as requiredunder the 2021 Special Rectification Program, which is under the review of governmentauthority.

New laws or regulations concerning data protection, or the interpretation and application ofexisting consumer and data protection laws or regulations, which is often uncertain and in flux,may be inconsistent with our practices. Complying with new laws, regulations and orders fromcompetent governmental authorities could cause us to incur substantial costs or require us tochange our business practices in a manner materially adverse to our business.

RISK FACTORS

– 60 –

If our security measures are breached, or if our products and services are subject toattacks that degrade or deny the ability of users to access our products and services, ourproducts and services may be perceived as not being secure, users and customers maycurtail or stop using our products and services and our business and operating resultsmay be harmed.

Our products and services involve the storage and transmission of users’ and customers’information, and security breaches expose us to a risk of loss of this information, litigation andpotential liability. We experience cyber-attacks of varying degrees on a regular basis, includinghacking into our user accounts and redirecting our user traffic to other websites, and we havebeen able to rectify attacks without significant impact to our operations in the past. Functionsthat facilitate interactivity with other websites, such as Weibo Connect, which among otherthings allows users to log in to partner websites using their Weibo identities, could increase thescope of access of hackers to user accounts.

Our security measures may also be breached due to employee error, malfeasance or otherwise.Additionally, outside parties may attempt to fraudulently induce employees, users or customersto disclose sensitive information in order to gain access to our data or our users’ or customers’data or accounts, or may otherwise obtain access to such data or accounts.

Since our users and customers may use their Weibo accounts to establish and maintain onlineidentities, unauthorized communications from Weibo accounts that have been compromisedmay damage their reputations and brands as well as ours. Any such breach or unauthorizedaccess could result in significant legal and financial exposure, damage to our reputation and aloss of confidence in the security of our products and services that could have an adverse effecton our business and operating results. Because the techniques used to obtain unauthorizedaccess, disable or degrade service or sabotage systems change frequently and often are notrecognized until launched against a target, we may be unable to anticipate these techniques orto implement adequate preventative measures. If an actual or perceived breach of our securityoccurs, the market perception of the effectiveness of our security measures could be harmed,we could lose users and customers and we may be exposed to significant legal and financialrisks, including legal claims and regulatory fines and penalties. Any of these actions could havea material and adverse effect on our business, reputation and operating results.

We rely on assumptions and estimates to calculate certain key operating metrics, and realor perceived inaccuracies in such metrics may harm our reputation and negatively affectour business.

The numbers of daily and monthly active users of Weibo, average spending per advertiser andnumber of advertisement customers are calculated using internal company data that has notbeen independently verified. While these numbers are based on what we believe to bereasonable calculations for the applicable periods of measurement, there are inherentchallenges in measuring usage and user engagement across our large user base. For example,there are a number of false or spam accounts in existence on Weibo. Although we continuouslycombat spam by suspending or terminating these accounts, our active user number may includea number of false or spam accounts and therefore may not accurately represent the actualnumber of active accounts. We treat each account as a separate user for purposes of calculatingour active users, because it may not always be possible to identify people and organizationsthat have set up more than one account. Additionally, some accounts used by organizations areused by many people within the organization. Accordingly, the calculations of our active usersmay not accurately reflect the actual number of people or organizations using Weibo.

RISK FACTORS

– 61 –

We regularly review and may adjust our processes for calculating our internal metrics toimprove their accuracy. Our measures of user growth and user engagement may differ fromestimates published by third parties or from similarly titled metrics used by our competitorsdue to differences in methodology. If customers, platform partners or investors do not perceiveour user metrics to be accurate representations of our user base or user engagement, or if wediscover material inaccuracies in our user metrics, our reputation may be harmed andcustomers and platform partners may be less willing to allocate their spending or resources toWeibo, which could negatively affect our business and operating results.

Our business is highly sensitive to the strength of our brand and market influence, andwe may not be able to maintain current or attract new users, customers and platformpartners for our products and services if we do not continue to increase the strength ofour brand and develop new brands successfully in the marketplace.

Our operational and financial performance is highly dependent on the strength of our brand andmarket influence. Such dependency will increase further as the number of internet and mobileusers as well as the number of market entrants in China grows. In order to retain existing andattract new internet users, customers and platform partners, we may need to substantiallyincrease our expenditures to create and maintain brand awareness and brand loyalty.

In addition, we receive a high degree of media coverage in Chinese communities around theworld. Negative coverage in the media of our company, including about our product quality andreliability, changes to our products and services, privacy and security practices, litigation,regulatory activity, the actions of our users, the experience of our users, platform partners andadvertisers with our products and services, alleged misconduct by our employees or businesspartners, unethical business practices, or rumors relating to our business, management andemployees, our shareholders and affiliates, our competitors and peers, even if inaccurate, couldthreaten our reputation and the perception of our brands. We cannot assure you that we will beable to defuse negative press coverage about our company to the satisfaction of our investors,users, customers and platform partners. If we are unable to defuse negative press coverageabout our company, our brand may suffer in the marketplace, our operational and financialperformance may be negatively impacted and the price of our Class A ordinary shares and/orADSs may decline.

User misconduct and inappropriate content may adversely impact our brand image,business and results of operations, and we may be held liable for information or contentdisplayed on, retrieved from or linked to our app or website or distributed to our users.

Our platform enables users to discover, create, and distribute content and interact with otherson our platform in real time. As it is difficult to control user behavior in real time, our platformmay be misused by individuals or groups of individuals who engage in, among other things,immoral, inappropriate, disrespectful, fraudulent or illegal activities. While we have developedtechnologies and a series of measures to detect inappropriate content and activities, we cannotguarantee that we will be able to fully prevent inappropriate content from being posted on ourplatform or inappropriate activities from being carried out on our platform. Moreover, as wehave limited control over the offline behavior of our users, to the extent that such behavior isassociated with our platform, our ability to protect our brand image and reputation may belimited. Our business and the public perception of our brand may be materially and adverselyaffected by misconduct conducted on or linked to our platform. It is possible that our users mayengage in conversations or activities on our platform that may be deemed illegal underapplicable laws and regulations. We may be subject to fines or other disciplinary actions,

If any of our users suffers or alleges to have sufferedphysical, financial or emotional harm arising from any contact initiated on our platform, wemay face civil lawsuits or other proceedings initiated by the affected user, or governmental orregulatory actions. Defending such actions could be costly and involve significant time andattention of our management and other resources, which could materially and adversely affectour business, financial condition, results of operations and prospects. There can be noassurance that we can detect all illegal or inappropriate content displayed on, retrieved fromor linked to our platform. If we are held liable for any of the aforementioned incidents in thefuture, our business, financial condition and results of operations may be materially andadversely affected.

Misconduct, error and failure to follow laws, regulations and our corporate governancepolicies by our employees may adversely impact our brand image, reputation, businessand results of operations, and we may be held liable for these inappropriate activities.

Misconduct, including illegal, fraudulent or collusive activities, unauthorized businessconducts and behavior, misuse of corporate authorization, or errors by our employees or theirfailure to perform their duties could subject us to legal liability and negative publicity. Ouremployees may conduct fraudulent activities to bypass our internal systems and to completeshadow transactions and/or transactions outside our official or authorized procedures. Theymay conduct activities in violation of law against unfair competition, which may expose us tounfair competition allegations and risks or conduct activities that may damage our reputation,corporate culture or internal working environment. We have experienced such incidents in thepast and may continue to experience or be subject to incidents of similar nature in the future.We terminated employment with the involved employees for serious misconducts andrecovered our losses from those employees in certain cases. While we have been strengtheningour code of conduct and related internal policies, including updating our employees’ code ofconduct and anti-bribery policy, we cannot assure you that such incidents will not occur in thefuture. It is not always possible to identify and deter such misconduct, and the precautions wetake to detect and prevent these activities may not be effective in controlling unknown orunmanaged risks or losses or in protecting us from governmental investigations or other actionsor lawsuits stemming from a failure to prevent such misconduct. Such misconduct coulddamage our brand and reputation, which could adversely affect our business and results ofoperations.

If our goodwill or intangible assets become impaired, we may be required to record asignificant charge to earnings.

We review our intangible assets for impairment when events or changes in circumstancesindicate that the carrying value may not be recoverable, such as a decline in stock price andmarket capitalization. We test goodwill for impairment at least once a year. If such goodwillor intangible assets are deemed to be impaired, an impairment loss equal to the amount bywhich the carrying amount exceeds the fair value of the assets would be recognized. We maybe required to record a significant charge in our financial statements during the period in whichany impairment of goodwill or intangible assets is determined, which would negatively affectour results of operations. We recorded an impairment charge of US$10.6 million for thegoodwill arising from certain game business acquisitions under value-added services segmentdue to failure in meeting forecasted financial performance that supports goodwill withoutprospect of recovering in 2018, and no impairment provision for goodwill and intangible assetswas recorded for the rest of Track Record Period.

RISK FACTORS

– 63 –

As of June 30, 2021, the total amount of our goodwill and intangible assets was US$270.8million. A substantial portion of the goodwill and intangible assets arose from the acquisitionsof the live streaming business of www.yizhibo.com, or Yizhibo, a live streaming platform inChina, in 2018 from Yixia Tech Co., Ltd., or Yixia Tech and Shanghai Jiamian InformationTechnology Co., Ltd., or JM Tech, in 2020, as well as the indirect acquisition of ShanghaiBenqu Network Technology Co., Ltd., the Wuta beauty camera app developer, in the secondquarter of 2021. Therefore, we may have to reassess and even record impairment loss if therespective industry prospects deteriorate.

The monetization of our services may require users to accept promoted marketing in theirfeeds or private messages, which may affect user experience and cause a decline in usertraffic and a delay in our monetization.

Weibo users typically can log in to their personal accounts to view feeds and private messagesfrom accounts that they have selected to follow. Social platform has been subject to negativecomments, and even lawsuits, for introducing promoted advertising into their users’information feeds. We started to test promoted products on Weibo at the end of 2012 and havealso received user complaints. If we are unable to address user complaints adequately, userexperience may be negatively affected, the monetization of our products and services may bedelayed and our user base or user engagement may decline, which may adversely impact ouroperations.

New technologies could block our advertisements. Users of PC and mobile devices mayenable technical measures that could hinder our traffic growth and limit our monetizationopportunities.

Technologies have been developed that can disable the display of our advertisements and thatprovide tools to users to opt out of our advertising products. Most of our revenues are derivedfrom fees paid to us by customers in connection with the display of advertisements to our users.In addition, our traffic growth is significantly dependent on content viewed via mobile devices,such as smartphones and tablets. Technologies and tools for personal computers and mobiledevices, such as operating systems, internet browsers, anti-virus software and otherapplications, as well as mobile application stores could set up technical measures to divert usertraffic, require a fee for the download of our products or block our products and servicesaltogether, which could adversely affect our overall traffic and ability to monetize our productsand services.

Our business and growth could suffer if we are unable to hire and retain key personnel.

We depend on the continued contributions of our senior management and other key employees,many of whom are difficult to replace. The loss of the services of any of our executive officersor other key employees could harm our business. Competition for qualified talent in China isintense. Our future success is dependent on our ability to attract a significant number ofqualified employees and retain existing key employees. If we are unable to do so, our businessand growth may be materially and adversely affected and the trading price of our Class Aordinary shares and/or ADSs could suffer. Our need to significantly increase the number of ourqualified employees and retain key employees may cause us to materially increasecompensation-related costs, including stock-based compensation.

RISK FACTORS

– 64 –

We have incurred and expect to continue to incur substantial stock-based compensationexpenses.

We have adopted share incentive plans in August 2010 and March 2014. See “Directors andSenior Management — Compensation — Share Incentive Plans” for a detailed discussion. Forthe years ended December 31, 2018, 2019, 2020 and for the six months ended June 30, 2021,we recorded US$41.0 million, US$61.3 million, US$67.1 million and US$36.2 million,respectively, in stock-based compensation expenses. We will continue to grant stock-basedcompensation in the future in order to attract and retain key personnel and employees.Consequently, our stock-based compensation expenses may be recurring and even significantlyincrease in absolute amount, which may have a material adverse effect on our results ofoperations.

Future investments in and acquisitions of complementary assets, technologies andbusinesses may fail and may result in equity or earnings dilution.

We have in the past and may continue to invest in or acquire assets, technologies andbusinesses that are complementary to our existing business. Our investments or acquisitionsmay not yield the results we expect. In addition, investments and acquisitions could result inthe use of substantial amounts of cash, potentially dilutive issuances of equity securities,significant amortization expenses related to intangible assets and exposure to potentialunknown liabilities of the acquired business. Moreover, the cost of identifying andconsummating investments and acquisitions, and integrating the acquired businesses into ours,may be significant, and the integration of acquired businesses may be disruptive to our existingbusiness operations. In addition, we may have to obtain approval from the relevant PRCgovernmental authorities for the investments and acquisitions and comply with any applicablePRC rules and regulations, which may be costly. Our investments and acquisitions may also besubject to merger control review and antitrust investigations under the PRC Anti-MonopolyLaw, the Interim Provisions on the Review of Concentrations of Undertakings and other PRCanti-monopoly laws, regulations and guidance. In the event that our investments andacquisitions are not successful, our financial condition and results of operations may bematerially and adversely affected.

Delay or failure of payment by our customers could harm our cash flows and profitability.

We are subject to credit risk arising from our accounts receivable from our customers. Ouraccounts receivable primarily include amounts due in one year or less from advertisingcustomers. As of December 31, 2018, 2019 and 2020 and June 30, 2021, our accountsreceivable due from third parties, net of respective allowances, were US$190.0 million,US$262.2 million, US$314.2 million and US$467.2 million, respectively. If any of ourcustomers’ cash flow, working capital, financial condition or results of operations deteriorates,it may be unable, or it may otherwise be unwilling, to pay accounts receivables owed to uspromptly or at all. Any substantial default or delay of a customer’s payment obligations maymaterially and adversely affect our working capital, financial condition and results ofoperations. As of 31 December 2018, 2019 and 2020 and June 30, 2021, our accountsreceivable due from Alibaba, net of respective allowances, were US$48.2 million, US$60.4million, US$135.3 million and US$123.0 million, respectively. Any substantial default or delayof Alibaba’s payment obligations may materially and adversely affect our working capital,financial condition and results of operations.

RISK FACTORS

– 65 –

We might not be able to fulfil our obligation in respect of deferred revenue, which mighthave impact on our cash or liquidity position.

Our deferred revenues related to unsatisfied performance obligations at the end of the periodare mainly from the customer advance of the advertising and marketing services and the salesof the fee-based services, such as VIP membership, live streaming, and virtual currency orin-game virtual items sold for game related services. The deferred revenues are recognizedbased on customers’ consumption or amortized on a straight-line basis through the serviceperiod for different products/services. As of December 31, 2018, 2019 and 2020 and June 30,2021, the balance of our deferred revenues were US$100.0 million, US$108.8 million,US$143.7 million, and US$146.1 million, respectively. Due to the generally short-termduration of the contracts, the majority of the performance obligations are satisfied in thefollowing reporting period. However, deferred revenue at any particular date may not berepresentative of actual revenue for any current or future period. Any failure to fulfil theobligations in respect of deferred revenue may have an adverse impact on our results ofoperations and liquidity.

We may face credit risk for our amount due from SINA.

Accounts receivable amounts directly related to Weibo but for which SINA will receivepayments and remit payments to us, as well as accounts receivable directly from SINA areincluded in the amount due from SINA. Our amount due from SINA increased from US$105.3million as of December 31, 2018, to US$384.8 million as of December 31, 2019, and furtherto US$548.9 million as of December 31, 2020. We recorded US$498.6 million of amount duefrom SINA as of June 30, 2021. As of December 31, 2018, 2019, 2020 and June 30, 2021, theamount due from SINA also included loans to and interest receivable from SINA of US$43.6million at an annual interest rate of 4.8%, US$236.6 million at an annual interest rate of 4.5%,US$547.9 million and US$480.7 million at annual interest rates ranging from 1.0% to 4.5% ofmaturity within one year, respectively. For a detailed description, see “Related PartyTransactions — Transactions with SINA.”

We cannot assure you that we will be able to collect payment fully and in a timely manner onour existing and future outstanding amount due from SINA. Our failure to collect paymentwould adversely impact our business operations and financial positions.

Our financial results could be adversely affected by our long-term investments.

We periodically review our investments in publicly traded companies, privately heldcompanies, and limited partnerships for impairment. If we conclude that any of theseinvestments is impaired, we will write down the asset to its fair value and take a correspondingcharge to our consolidated statements of comprehensive income. For the fiscal years endedDecember 31, 2018, 2019, 2020 and the six months ended June 30, 2021, we recognizedimpairment charges of US$23.6 million, US$230.9 million, US$126.8 million and US$66.6million, respectively, on the carrying value of our investments. We may continue to incurimpairment charges in the future, which could depress our profitability or subject us to incura net loss.

As of June 30, 2021, our investments included US$881.7 million in private companies, whichmay not have the resources nor level of controls in place like public companies to timely andaccurately provide updates about their company to us. Furthermore, many of our investmentsare at an early, pre-revenue stage of development, and their impairment may be difficult toassess as market information on internet-related startups is not readily available. After our

RISK FACTORS

– 66 –

adoption of ASU 2016-01 “Classification and Measurement of Financial Instruments” startingJanuary 1, 2018, we measure long-term investments other than equity method investments atfair value through earnings. Our investments other than equity method are subject to a widevariety of market related risks that could substantially reduce or increase the fair value of ourholdings. For example, identification of observable price change in orderly transaction forthose investments without readily determinable fair value may result in our recognition of gainor loss on such investments.

Determination of estimated fair value of these investments require complex and subjectivejudgments due to their limited financial and operating history, unique business risks andlimited public information. Consequently, we may not receive information about ourinvestments on a timely basis to properly account for them. We recognized a net loss ofUS$69.5 million for the six months ended June 30, 2021 as a result of fair value changes. Weare unable to control these factors and an impairment charge recognized by us, especiallyuntimely recorded, may adversely impact our financial results and share price.

Fluctuation of fair value change of short-term investments may affect our financialposition.

During the Track Record Period, we have spent a portion of our capital in short-terminvestments, which represent bank time deposits and certain wealth management products. Forwealth management products whose interest rates are indexed to performance of the underlyingassets, we carried these investments at fair value. We measure the fair value of our short-terminvestments on a recurring basis and the fair value of our short-term investments aredetermined based on the quoted market price for similar products. Changes in fair value arereflected in our consolidated statements of income.

Any change in securities prices and market conditions could lead to volatility in the fair valuesof our short-term investments accounted for at fair value, which could impact our financialcondition and results of operations and may also impact our ability to dispose of theseinvestments at favorable prices.

If we cannot obtain sufficient cash when we need it, we may not be able to meet ourpayment obligations under our notes.

In October 2017, we issued US$900 million principal amount of convertible senior notes due2022, which we refer to as 2022 Notes in this document. The 2022 Notes bear an annualinterest rate of 1.25%, payable semiannually in arrears on May 15 and November 15 of eachyear, beginning on May 15, 2018, and will mature on November 15, 2022. In July 2019, weissued US$800 million in aggregate principal amount of senior notes due 2024, which we referto as 2024 Notes in this document. The 2024 Notes were issued at par value and bear an annualinterest rate of 3.50%, payable semiannually in arrears on January 5 and July 5 of each year,beginning on January 5, 2020. The 2024 Notes will mature on July 5, 2024, unless previouslyrepurchased or redeemed in accordance with their terms prior to maturity. In July 2020, weissued US$750 million in aggregate principal amount of senior notes due 2030, which we referto as 2030 Notes in this document. The 2030 Notes bear an annual interest rate of 3.375%,payable semiannually in arrears on January 8 and July 8 of each year, beginning on January 8,2021. The 2030 Notes will mature on July 8, 2030, unless previously repurchased or redeemedin accordance with their terms prior to maturity. We may not have sufficient funds to pay theinterest or fulfill other obligations under these notes.

RISK FACTORS

– 67 –

We derive most of our revenues from, and hold most of our assets through, our subsidiaries.As a result, we may rely in part upon distributions and advances from our subsidiaries in orderto help us meet our payment obligations under the notes and our other obligations. Oursubsidiaries are distinct legal entities and do not have any obligation, legal or otherwise, toprovide us with distributions or advances. We may face tax or other adverse consequences, orlegal limitations, on our ability to obtain funds from these entities. In addition, our ability toobtain external financing in the future is subject to a variety of uncertainties, including:

• our financial condition, results of operations and cash flows;

• general market conditions for financing activities by internet companies; and

• economic, political and other conditions in the PRC and elsewhere.

If we are unable to obtain funding in a timely manner or on commercially acceptable terms, wemay not be able to meet our payment obligations under our convertible notes. If we fail to payinterest on the notes, we will be in default under the indenture governing the notes, which inturn may constitute a default under existing and future agreements governing our indebtedness.

We may need additional capital, and financing may not be available on terms acceptableto us, or at all.

We may require additional cash resources if we experience changes in business conditions orother developments. In addition to the 2022 Notes, 2024 Notes and 2030 Notes, we may seekto issue equity or equity linked securities or obtain debt financing. The issuance and sale ofadditional equity would result in further dilution to our shareholders. The incurrence ofindebtedness would result in increased fixed obligations and could result in operatingcovenants that would restrict our operations. We cannot assure you that financing will beavailable in amounts or on terms acceptable to us, if at all.

Many of our products and services contain open source software, and we license some ofour software through open source projects, which may pose particular risks to ourproprietary software, products, and services in a manner that could have a negative effecton our business.

We use open source software in our products and services and will use open source softwarein the future. In addition, from time to time, we contribute software source code to open sourceprojects under open source licenses or release internal software projects under open sourcelicenses, and anticipate doing so in the future. The terms of many open source licenses to whichwe are subject have not been interpreted by domestic or foreign courts, and there is a risk thatopen source software licenses could be construed in a manner that imposes unanticipatedconditions or restrictions on our ability to provide or distribute our products or services.Additionally, we may from time to time face claims from third parties claiming ownership of,or demanding release of, the open source software or derivative works that we developed usingsuch software, which could include our proprietary source code, or otherwise seeking toenforce the terms of the applicable open source license. These claims could result in litigationand could require us to make our software source code freely available, purchase a costlylicense or cease offering the implicated products or services unless and until we canre-engineer them to avoid infringement. This re-engineering process could require significantadditional research and development resources, and we may not be able to complete itsuccessfully. In addition to risks related to license requirements, use of certain open source

RISK FACTORS

– 68 –

software can lead to greater risks than use of third-party commercial software, as open sourcelicensors generally do not provide warranties or controls on the origin of software.Additionally, because any software source code we contribute to open source projects ispublicly available, our ability to protect our intellectual property rights with respect to suchsoftware source code may be limited or lost entirely, and we are unable to prevent ourcompetitors or others from using such contributed software source code. Any of these riskscould be difficult to eliminate or manage, and, if not addressed, could have a negative effecton our business, financial condition and operating results.

We may not be able to adequately protect our intellectual property, which could cause usto be less competitive.

We rely on a combination of patent, copyright, trademark and trade secret laws and restrictionson disclosure to protect our intellectual property rights. Despite our efforts to protect ourproprietary rights, third parties may attempt to copy or otherwise obtain and use our intellectualproperty, seek court declarations that they do not infringe upon our intellectual property rights,or allege that certain of our products and services, or user content, infringe their intellectualproperty rights. Monitoring unauthorized use of our intellectual property is difficult and costly,and we cannot be certain that the steps we have taken will prevent misappropriation of ourintellectual property. From time to time, we may have to resort to litigation to enforce or defendour intellectual property rights, which could result in substantial costs and diversion of ourresources. For example, the Trademark Review and Adjudication Board, or TRAB, issueddecisions in June and July, 2017 to cancel the two trademarks owned by Weibo Interactive dueto the lack of the proof of use. We have appealed TRAB’s decisions through the BeijingIntellectual Property Court. On December 25, 2017, Beijing Intellectual Property Court madetwo first instance judgments, each lifting TRAB’s decision and instructing TRAB to issue newdecisions on the application for review regarding the two trademarks. On May 8, 2018, TRABissued that the trademarks are valid for all registered items including computer programs andcomputer game software.

We may be subject to intellectual property infringement claims or other allegations bythird parties for information or content displayed on, retrieved from or linked to ourplatform, or distributed to our users, which may materially and adversely affect ourbusiness, financial condition and prospects.

Companies in the internet, technology and media industries are frequently involved inlitigation based on allegations of infringement of intellectual property rights, unfaircompetition, invasion of privacy, defamation, and other violations of other parties’ rights. Inaddition, various “non-practicing entities” that own patents and other intellectual propertyrights often attempt to aggressively assert their rights in order to extract value from technologycompanies. The validity, enforceability and scope of protection of intellectual property rightsin internet-related industries, particularly in China, are uncertain and still evolving. As we faceincreasing competition and as litigation becomes more common in China in resolvingcommercial disputes, we face a higher risk of being the subject of intellectual propertyinfringement claims. Furthermore, from time to time we may introduce or acquire new productsor services, including in areas where we historically have not competed, which could increaseour exposure to patent and other intellectual property claims from competitors and non-practicing entities.

We allow users to upload written materials, images, pictures and other content on our platformand download, share, link to and otherwise access games and applications (some of which aredeveloped by third parties) as well as audio, video and other content either on our platform orfrom other websites through our platform. We have procedures designed to reduce thelikelihood that content might be used without proper licenses or third-party consents. However,these procedures may not be effective in preventing the unauthorized posting of copyrightedcontent.

With respect to games and applications available on our platform, we have procedures designedto reduce the likelihood of infringement. However, such procedures might not be effective inpreventing games and applications, particularly those developed by third parties, frominfringing upon other parties’ rights. We may face liability for copyright or trademarkinfringement, defamation, unfair competition, libel, negligence, and other claims based on thenature and content of the materials that are delivered, shared or otherwise accessed through ourplatform.

We may receive notice from patent holders and other parties alleging that certain of ourproducts and services, or user content, infringe their intellectual property rights. Defendingintellectual property litigation is costly and can impose a significant burden on ourmanagement and employees, and there can be no assurances that favorable final outcomes willbe obtained in all cases. Such claims, even if they do not result in liability, may harm ourreputation. Any resulting liability or expenses, or changes required to our platform to reducethe risk of future liability, may have a material adverse effect on our business, financialcondition and prospects.

User growth and engagement depend upon effective interoperation with operatingsystems, networks, devices, web browsers and standards that we do not control.

We make our products and services available across a variety of operating systems and throughwebsites. We are dependent on the interoperability of our products and services with populardevices, desktop and mobile operating systems and web browsers that we do not control, suchas Windows, Mac OS, Android, iOS, and others. Any changes in such systems, devices or webbrowsers that degrade the functionality of our products and services or give preferentialtreatment to competitive products or services could adversely affect usage of our products andservices. Further, if the number of platforms for which we develop our products increases, itwill result in an increase in our costs and expenses. In order to deliver high quality productsand services, it is important that our products and services work well with a range of operatingsystems, networks, devices, web browsers and standards that we do not control. In addition,because a majority of our users access our products and services through mobile devices, weare particularly dependent on the interoperability of our products and services with mobiledevices and operating systems. We may not be successful in developing relationships with keyparticipants in the mobile industry or in developing products or services that operateeffectively with these operating systems, networks, devices, web browsers and standards. In theevent that it is difficult for our users to access and use our products and services, particularlyon their mobile devices, our user growth and user engagement could be harmed, and ourbusiness and operating results could be adversely affected.

Our operations depend on the performance of the internet infrastructure and fixedtelecommunications networks in China.

Almost all access to the internet in China is maintained through state-ownedtelecommunication operators under the administrative control and regulatory supervision of theMinistry of Industry and Information Technology, or the MIIT. Moreover, we primarily rely ona limited number of telecommunication service providers to provide us with datacommunications capacity through local telecommunications lines and internet data centers tohost our servers. We have limited access to alternative networks or services in the event ofdisruptions, failures or other problems with China’s internet infrastructure or the fixedtelecommunications networks provided by telecommunication service providers. Web traffic inChina has experienced significant growth during the past few years. Effective bandwidth andserver storage at internet data centers in large cities such as Beijing are scarce. With theexpansion of our business, we may be required to upgrade our technology and infrastructureto keep up with the increasing traffic on our platform. We had not experienced materialdisruptions to our business operations as a result of service capacity constraints during theTrack Record Period. However, we cannot assure you that the internet infrastructure and thefixed telecommunications networks in China will be able to support the demands associatedwith the continued growth in internet usage. If we are unable to increase our online content andservice delivering capacity accordingly, we may not be able to continuously grow our traffic,and the adoption of our products and services may be hindered, which could adversely impactour business and our share price.

In addition, we have no control over the costs of the services provided by telecommunicationservice providers. If the prices we pay for telecommunications and internet services risesignificantly, our results of operations may be materially and adversely affected. Furthermore,if internet access fees or other charges to internet users increase, particularly as content shiftstoward video, some users may be prevented from accessing the internet and thus cause thegrowth of internet users to decelerate. Such deceleration may adversely affect our ability tocontinue to expand our user base and increase our attractiveness to online customers.

Our business and operating results may be harmed by service disruptions, or by ourfailure to timely and effectively scale and adapt our existing technology andinfrastructure.

One of the reasons people come to Weibo is for real-time information. We have experienced,and may in the future experience, service disruptions, outages and other performance problemsdue to a variety of factors, including infrastructure changes, human or software errors,hardware failure, capacity constraints due to an overwhelming number of people accessing ourproducts and services simultaneously, computer viruses and denial of service, fraud andsecurity attacks. Any disruption or failure in our infrastructure could hinder our ability tohandle existing or increased traffic on our platform or cause us to lose content stored on ourplatform, which could significantly harm our business and our ability to retain existing usersand attract new users.

As the number of our users increases and our users generate more content, including photos andvideos on our platform, we may be required to expand and adapt our technology andinfrastructure to continue to reliably store and analyze this content. It may become increasinglydifficult to maintain and improve the performance of our products and services, especiallyduring peak usage times, as our products and services become more complex and our usertraffic increases. In addition, because we lease our data center facilities, we cannot be assuredthat we will be able to expand our data center infrastructure to meet user demand in a timelymanner, or on favorable economic terms, or at all. We rely on SINA, our controlling

RISK FACTORS

– 71 –

shareholder, and third-party vendors to provide infrastructure services. We cannot assure youthat their infrastructure will operate without interruptions and that we can maintain arelationship with these parties on favorable economic terms. If our users are unable to accessWeibo or we are not able to make information available rapidly on Weibo, or at all, users maybecome frustrated and seek other channels to obtain the information, and may not return toWeibo or use Weibo as often in the future, or at all. This would negatively impact our abilityto attract users and customers and maintain the level of engagement of our users.

We prioritize product innovation and user experience over short-term operating results,which may harm our revenues and operating results.

We encourage employees to quickly develop and help us launch new and innovative features.We focus on improving the user experience for our products and services and on developingnew and improved products and services for the customers on our platform. We prioritizeinnovation and the experience for users and customers on Weibo over short-term operatingresults. We frequently make product and service decisions that may reduce our short-termoperating results if we believe that the decisions are consistent with our goals to improve theuser experience and performance for customers, which we believe will improve our operatingresults over the long term. These decisions may not be consistent with the short-termexpectations of investors and may not produce the long-term benefits that we expect, in whichcase our user growth and user engagement, our relationships with customers and our businessand operating results could be adversely and materially harmed. In addition, our focus on theuser experience may negatively impact our relationships with our existing or prospectivecustomers. This could result in a loss of customers and platform partners, which couldadversely and materially harm our revenues and operating results.

We may face lawsuits or incur liability as a result of content published, made availablethrough, or linked to our social media platform.

As a social media platform, we have faced and will continue to face liability relating to contentthat is published, made available through, or linked to our platform. In particular, the natureof our business exposes us to claims related to defamation, intellectual property rights, rightsof publicity and privacy, illegal content, content regulation and personal injury torts. The lawrelating to the liability of providers of online products or services for activities of their usersremains somewhat unsettled in China. In addition, the public nature of communications on ourplatform exposes us to risks arising from the creation of impersonation accounts intended tobe attributed to our users or customers. We could incur significant costs investigating anddefending these claims. If we incur costs or liability as a result of these events, our business,financial condition and operating results could be adversely affected.

We may be subject to litigation for user-generated content provided on our platform,which may be time-consuming and costly to defend.

Our platform is open to the public for posting user-generated content. Although we haverequired our users to post only legally compliant and inoffensive materials and have set upscreening procedures, our screening procedures may fail to screen out all potentially offensiveor non-compliant user-generated content. Even if properly screened, a third party may still finduser-generated content postings on our platform offensive and take actions against us inconnection with the posting of such information. As with other companies who provideuser-generated content on their websites, we have had to deal with such claims in the past andanticipate that such claims will increase as user-generated content becomes more popular inChina. Any such claim, with or without merit, could be time-consuming and costly to defend,and may result in litigation and divert management’s attention and resources.

We may face certain risks related to financial products available on our Weibo wallet.

Weibo wallet enables users to purchase different types of financial products and services,including micro-loan facilitation offered by our related party, insurance, funds and otherfinancial services offered by Weibo’s business partners who are third-parties with relevantlicenses. The Chinese laws and regulations on internet finance have been developing rapidlyin recent years. To ensure the services provided on Weibo wallet remain in compliance withPRC laws and regulations on internet finance services, we have made relevant adjustments tothe services available through Weibo wallet from time to time over the past several years. Wewere not subject to any penalty or punishment with respect to our services available on Weibowallet during the Track Record Period.

For example, on March 28, 2018, the Internet Financing Risks Special Rectification WorkLeading Group under the State Council issued a Notice on Strengthening the Rectification andInspection of Asset Management Operations via Internet (《關於加大通過互聯網開展資產管理業務整治力度及開展驗收工作的通知》), which requires any entity that issues or sells fund andasset management products via the internet to obtain an asset management business license orasset management product sales license issued by the central financial managementdepartment. We have engaged third parties with relevant operating licenses to provide theservices and products legally. After our adjustments, Weibo wallet now acts as a platform for,instead of an operator of, the financial products, including micro-loan facilitation offered byour related party, insurance, funds and other financial services offered by Weibo’s businesspartners who are third parties with relevant licenses. As advised by our PRC legal adviser, suchpractice is in compliance with the current PRC laws and regulations.

On January 13, 2021, the General Office of the China Banking and Insurance RegulatoryCommission and the General Office of the People’s Bank of China jointly issued a Circular onRegulating the Personal Deposit Business Conducted by Commercial Banks through theInternet (《關於規範商業銀行通過互聯網開展個人存款業務有關事項的通知》), pursuant towhich commercial banks are not allowed to engage in the business of providing fixed depositsor time-demand optional deposits through non-self-operated online platforms. On February 19,2021, the General Office of the China Banking and Insurance Regulatory Commission issueda Circular on Further Regulating the Internet Loan Business of Commercial Banks, pursuantto which local banks engaged in online loan business shall serve local customers and are notallowed to operate online loan business outside of their registered local administrative areas,subject to certain exemptions. As such, we ceased our internet deposit cooperation withcommercial banks and delisted all internet deposit services.

On March 12, 2021, the People’s Bank of China issued the Announcement of the People’s Bankof China [2021] No.3 (《中國人民銀行公告[2021]第3號》), pursuant to which all loanproducts shall explicitly indicate their annualized loan interest rate, and we have included therequested information timely after the issuance of this announcement.

On December 7, 2020, the China Banking and Insurance Regulatory Commission issued theMeasures for the Regulation of Internet Insurance Business (《互聯網保險業務監管辦法》),effective February 1, 2021, which provides that self-operated network platforms with insurancesales or insurance application functions and information management systems shall be undersecurity protection of class III or above, with appropriate customer information protectionsystems. As such, our cooperation partner for the relevant business is preparing for anapplication for the certification of security protection of Class III for our core system andanticipate completing this before December 31, 2021. In addition, we formulated Rules onUsers’ Rights Protection of Weibo Insurance Mall to strengthen the protection of users’information and privacy rights.

Although we believe our operation of Weibo wallet complies with relevant PRC laws andregulations in all material aspects during the Track Record Period, we cannot assure you thatthe government authorities will deem the business operation by our related party or ourthird-party business partners to be compliant with PRC laws and regulations. If any of thefinancial products or services available on Weibo wallet are found to be in violation of relevantregulations, Weibo may face warnings, fines, confiscation of illegal gains, license revocationsor the discontinuation of the relevant business, and our business, financial condition andoperating results could be adversely affected.

We have limited business insurance coverage.

The insurance industry in China is still young and the business insurance products offered inChina are limited. We have limited business liability or disruption insurance coverage for ouroperations. Any business disruption, litigation or natural disaster may cause us to incursubstantial costs and divert our resources.

We face risks related to health epidemics and other outbreaks, such as the outbreak ofCOVID-19, as well as natural disasters, which could significantly disrupt our operationsand adversely affect our business, financial condition or results of operation.

In addition to the impact of COVID-19, our business could be adversely affected by the effectsof Ebola virus disease, H1N1 flu, H7N9 flu, avian flu, Severe Acute Respiratory Syndrome, orSARS, or other epidemics. Our business operations could be disrupted if any of our employeesis suspected of having Ebola virus disease, H1N1 flu, H7N9 flu, avian flu, SARS, COVID-19or other epidemics, since it could require our employees to be quarantined and/or our officesto be disinfected. In addition, our results of operations and financial performance could beadversely affected to the extent that any of these epidemics harms the Chinese economy ingeneral.

In early 2020, to contain the spread of COVID-19, the Chinese government had taken certainemergency measures, including extension of the Lunar New Year holidays, implementation oftravel bans, blockade of certain roads and suspension of operation factories and businesses.These emergency measures have been significantly relaxed by the Chinese government as ofthe Latest Practicable Date. However, there has been an increasing number of COVID-19cases, including the COVID-19 Delta variant cases, in various cities in China, and the Chineselocal authorities have reinstated certain measures to keep COVID-19 in check, including travelrestrictions and stay-at-home orders. In addition, the highly-transmissible Delta variant ofCOVID-19 has caused authorities in various countries to reimpose restrictions such as maskmandates, curfews and prohibitions on large gatherings. The COVID-19 pandemic has causedmaterial negative impact to our total revenues, slower collection of accounts receivables andadditional allowance for credit losses in the year of 2020, particularly in its first half. Althoughour advertising business has gradually recovered, if the impact of COVID-19, includingsubsequent outbreaks driven by new variants of COVID-19, is prolonged or worsens further,it may still disrupt our business, which may in turn adversely affect our revenue and financialconditions. Our headquarters are located in Beijing, and we currently lease the majority of ouroffices in various parts of China to support our operations. This outbreak of communicabledisease has caused, and may cause again in the future, companies, including us and certain ofour business partners, to implement temporary adjustment of work schemes allowingemployees to work from home and adopt remote collaboration. We have taken measures toreduce the impact of this epidemic outbreak, including upgrading our telecommuting system,monitoring our employees’ health on a daily basis, arranging shifts of our employees workingonsite and from home to avoid infection transmission and optimizing our technology system tosupport potential growth in user traffic. There remain significant uncertainties surrounding

COVID-19 and its further development as a global pandemic, including the effectiveness ofvaccine programs against existing and any new variants of COVID-19, and their impacts on ourcustomers’ advertising budget and spending more broadly. The extent to which COVID-19,including subsequent outbreaks driven by new variants of COVID-19, impacts our financialposition, results of operations and cash flows in 2021 will depend on future developments,which are highly uncertain and cannot be predicted, including new information which mayemerge concerning the severity of COVID-19, the spread of new variants, the actions to containthe coronavirus or treat its impact, the availability of vaccine and treatment for COVID-19,among others.

We are also vulnerable to natural disasters and other calamities. Fire, floods, typhoons,earthquakes, power loss, telecommunications failures, break-ins, war, riots, terrorist attacks orsimilar events may give rise to server interruptions, breakdowns, system failures, technologyplatform failures or internet failures, which could cause the loss or corruption of data ormalfunctions of software or hardware as well as adversely affect our ability to provide productsand services on our platform.

Divestitures of businesses and assets may have a material and adverse effect on ourbusiness and financial condition.

We may undertake in the future, partial or complete divestitures or other disposal transactionsin connection with certain of our businesses and assets, particularly ones that are not closelyrelated to our core focus areas or might require excessive resources or financial capital, to helpour company meet its objectives. These decisions are largely based on our management’sassessment of the business models and likelihood of success of these businesses. However, ourjudgment could be inaccurate, and we may not achieve the desired strategic and financialbenefits from these transactions. Our financial results could be adversely affected by theimpact from the loss of earnings and corporate overhead contribution/allocation associatedwith divested businesses.

Dispositions may also involve continued financial involvement in the divested business, suchas through guarantees, indemnities or other financial obligations. Under these arrangements,performance by the divested businesses or other conditions outside of our control could affectour future financial results. We may also be exposed to negative publicity as a result of thepotential misconception that the divested business is still part of our consolidated group. Onthe other hand, we cannot assure you that the divesting business would not pursue opportunitiesto provide services to our competitors or other opportunities that would conflict with ourinterests. If any conflicts of interest that may arise between the divesting business and uscannot be resolved in our favor, our business, financial condition, results of operations couldbe materially and adversely affected.

Furthermore, reducing or eliminating our ownership interests in these businesses mightnegatively affect our operations, prospects, or long-term value. We may lose access toresources or know-how that would have been useful in the development of our own business.Our ability to diversify or expand our existing businesses or to move into new areas of businessmay be reduced, and we may have to modify our business strategy to focus more exclusivelyon areas of business where we already possess the necessary expertise. We may sell ourinterests too early, and thus forego gains that we otherwise would have received had we notsold. Selecting businesses to dispose of or spin off, finding buyers for them (or the equityinterests in them to be sold) and negotiating prices for what may be relatively illiquidownership interests with no easily ascertainable fair market value will also require significantattention from our management and may divert resources from our existing business, which inturn could have an adverse effect on our business operations.

RISKS RELATING TO OUR CARVE-OUT FROM SINA AND OUR RELATIONSHIPWITH SINA

We rely on SINA for a broad range of support and there can be no assurance that SINAwill continue to provide the same level of support.

SINA is a leading internet media company in China, and our social media business hasbenefited significantly from SINA’s strong market position in China and its expertise in bothinternet and media-related businesses. For example, our advertising and marketing revenueshave benefited from SINA’s ability to attract large brand advertisers that are interested inadvertising on the internet. Prior to our initial public offering in April 2014, SINA provided uswith financial, administrative, sales and marketing, human resources and legal services and theservices of a number of its executives and employees. After we became a stand-alone publiccompany, SINA has continued to provide us with certain support services.

Although we have entered into a series of agreements with SINA relating to our ongoingbusiness partnership and service arrangements with SINA, we cannot assure you we willcontinue to receive the same level of support from SINA going forward. To the extent thatSINA does not continue to provide us with such support, we will need to create our ownsupport systems. We may encounter operational, administrative and strategic difficulties if weare to adjust to providing these support services on our own, which may cause us to reactslower than our competitors to industry changes, may divert our management’s attention fromrunning our business or may otherwise harm our operations.

As a result of this merger, SINAbecame a wholly owned subsidiary of Sina Group Holding Company Limited, which is awholly owned subsidiary of New Wave MMXV Limited, a business company incorporated inthe British Virgin Islands and controlled by Mr. Charles Chao. Following the completion of themerger, SINA has ceased to be a reporting company under the Exchange Act and its shares haveceased trading on NASDAQ.

RISK FACTORS

– 76 –

Our agreements with SINA may be less favorable to us than similar agreements negotiatedbetween unaffiliated parties. In particular, our non-competition agreement with SINAlimits the scope of business that we are allowed to conduct.

We have entered into a series of agreements with SINA and the terms of such agreements maybe less favorable to us than would be the case if they were negotiated with unaffiliated thirdparties. In particular, under the non-competition agreement we have entered into with SINA,we agreed not to, during the non-competition period (which will end on the later of (1) fiveyears after the first date when SINA ceases to own in aggregate at least 20% of the votingpower of our then outstanding securities and (2) the fifteenth anniversary of the completion ofour initial public offering in 2014), compete with SINA in the business currently conducted bySINA, as described in its periodic filings with the SEC, other than the microblogging and socialnetworking business currently operated by us and any business developed by us operatingunder either the domain names or the brands owned by us as of the date of the agreement. Suchcontractual limitations significantly affect our ability to diversify our revenue sources and maymaterially and adversely impact our business and prospects should the growth of social mediain China slow down. In addition, pursuant to our master transaction agreement with SINA, wehave agreed to indemnify SINA for liabilities arising from litigation and other contingenciesrelated to our business and assumed these liabilities as part of our carve-out from SINA. Theallocation of assets and liabilities between SINA and our company may not reflect theallocation that would have been reached by two unaffiliated parties. Moreover, so long as SINAcontinues to control us, we may not be able to bring a legal claim against SINA in the eventof contractual breach, notwithstanding our contractual rights under the agreements describedabove and other inter-company agreements entered into from time to time.

Our sales, marketing and brand promotion have benefited significantly from ourassociation with SINA. Any negative development in SINA’s market position or brandrecognition may materially and adversely affect our marketing efforts and the strength ofour brand.

As a controlled subsidiary of SINA, we have benefited significantly from our association withSINA in marketing our brand and our platform. For example, we have benefited by providingservices to SINA’s clients. We also benefit from SINA’s strong brand recognition in China,which has provided us credibility and a broad marketing reach. If SINA loses its marketposition, the effectiveness of our marketing efforts through our association with SINA may bematerially and adversely affected. In addition, any negative publicity associated with SINAwill likely have an adverse impact on the effectiveness of our marketing as well as ourreputation and our brand.

SINA will control the outcome of shareholder actions in our company.

SINA held approximately 44.6% of our total issued and outstanding ordinary shares,representing 70.7% of our total voting power as of June 30, 2021. SINA has advised us that itdoes not anticipate disposing of its voting control in us in the near future. SINA’s voting powergives it the power to control actions that require shareholder approval under Cayman Islandslaw, our memorandum and articles of association and Nasdaq requirements, including theelection and removal of a majority of our board of directors, approval of significant mergersand acquisitions and other business combinations, changes to our memorandum and articles ofassociation, the number of shares available for issuance under share incentive plans, and theissuance of significant amounts of our ordinary shares in private placements.

RISK FACTORS

– 77 –

SINA’s voting control may cause transactions to occur that might not be beneficial to holdersof Class A ordinary shares and/or ADSs and may prevent transactions that would be beneficialto you. For example, SINA’s voting control may prevent a transaction involving a change ofcontrol of us, including transactions in which you as a holder of our Class A ordinary sharesand/or ADSs might otherwise receive a premium for your securities over the then-currentmarket price. In addition, SINA is not prohibited from selling a controlling interest in us to athird party and may do so without the approval of the Class A ordinary shares and/or ADSholders and without providing for a purchase of the Class A ordinary shares held by investorsand/or ADSs held by the ADS holders. If SINA is acquired or otherwise undergoes a changeof control, any acquirer or successor will be entitled to exercise the voting control andcontractual rights of SINA, and may do so in a manner that could vary significantly from thatof SINA.

We are a “controlled company” within the meaning of the Nasdaq Stock Market Rulesand, as a result, may rely on exemptions from certain corporate governance requirementsthat provide protection to shareholders of other companies.

We are a “controlled company” as defined under the Nasdaq Stock Market Rules because SINAholds more than 50% of our voting power. For so long as we remain a controlled companyunder that definition, we are permitted to elect to rely, and will rely, on certain exemptionsfrom corporate governance rules, including:

• an exemption from the rule that our director nominees must be selected or recommendedsolely by independent directors; and

• an exemption from having a corporate governance and nominating committee that iscomposed entirely of independent directors with a written charter addressing thecommittee’s purpose and responsibilities.

As a result, the ADS holders do not have the same protection afforded to shareholders ofcompanies that are subject to these corporate governance requirements.

We may have conflicts of interest with SINA and, because of SINA’s controlling ownershipinterest in our company, we may not be able to resolve such conflicts on favorable termsfor us.

Conflicts of interest may arise between SINA and us in a number of areas relating to our pastand ongoing relationships. Potential conflicts of interest that we have identified include thefollowing:

• Indemnification arrangements with SINA. We have agreed to indemnify SINA withrespect to lawsuits and other matters relating to our social media business, includingoperations of that business when it was a private company and a subsidiary of SINA.These indemnification arrangements could result in our having interests that are adverseto those of SINA, for example, with respect to settlement arrangements in litigation. Inaddition, under these arrangements, we have agreed to reimburse SINA for liabilitiesincurred (including legal defense costs) in connection with any litigation, while SINA willbe the party prosecuting or defending the litigation.

RISK FACTORS

– 78 –

• Non-competition arrangements with SINA. We and SINA have entered into a non-competition agreement under which we agree not to compete with each other’s corebusiness. SINA agrees not to compete with us in a business that is of the same nature asthe microblogging and social networking business operated by us as of the date of theagreement. We agree not to compete with SINA in the business currently conducted bySINA, as described in its periodic filings with the SEC, other than the microblogging andsocial networking business operated by us as of the date of the agreement.

• Employee recruiting and retention. Because both SINA and we are engaged internet-related businesses in China, we may compete with SINA in the hiring of new employees,in particular with respect to media and advertising-related matters. We have a non-solicitation arrangement with SINA that restricts us and SINA from hiring any of eachother’s employees.

• Our board members or executive officers may have conflicts of interest. Two directors ofour company are also executive officers of SINA. In addition, we may continue to grantincentive share compensation to SINA’s employees and consultants from time to time.These relationships could create, or appear to create, conflicts of interest when thesepersons are faced with decisions with potentially different implications for SINA and us.

• Sale of shares in our company. SINA may decide to sell all or a portion of our shares thatit holds to a third party, including to one of our competitors, thereby giving that thirdparty substantial influence over our business and our affairs. Such a sale could be contraryto the interests of our employees or our other shareholders.

• Allocation of business opportunities. Business opportunities may arise that both we andSINA find attractive, and which would complement our respective businesses. SINA maydecide to take the opportunities itself, which would prevent us from taking advantage ofthose opportunities.

• Developing business relationships with SINA’s competitors. So long as SINA remains asour controlling shareholder, we may be limited in our ability to do business with itscompetitors, such as other online media companies in China. This may limit our abilityto market our services for the best interests of our company and our other shareholders.

Although our company has become a stand-alone public company, we expect to operate, for aslong as SINA is our controlling shareholder, as an affiliate of SINA. SINA may from time totime make strategic decisions that it believes are in the best interests of its business as a whole,including our company. These decisions may be different from the decisions that we wouldhave made on our own. SINA’s decisions with respect to us or our business may be resolvedin ways that favor SINA and therefore SINA’s own shareholders, which may not coincide withthe interests of our other shareholders. We may not be able to resolve any potential conflicts,and even if we do so, the resolution may be less favorable to us than if we were dealing witha non-controlling shareholder. Even if both parties seek to transact business on terms intendedto approximate those that could have been achieved among unaffiliated parties, this may notsucceed in practice.

RISKS RELATING TO OUR CORPORATE STRUCTURE

Uncertainties exist with respect to the interpretation and implementation of the PRCForeign Investment Law and how it may impact the viability of our current corporatestructure, corporate governance and business operations.

The National People’s Congress approved the Foreign Investment Law (《中華人民共和國外商投資法》) on March 15, 2019 and the State Council approved the Regulation onImplementing the Foreign Investment Law (《中華人民共和國外商投資法實施條例》) (the“Implementation Regulations”) on December 26, 2019, effective from January 1, 2020, whichreplaced the trio of existing laws regulating foreign investment in China, namely, theSino-foreign Equity Joint Venture Enterprise Law (《中外合資經營企業法》), the Sino-foreignCooperative Joint Venture Enterprise Law (《中外合作經營企業法》) and the Wholly Foreign-invested Enterprise Law (《外資企業法》), together with their implementation rules andancillary regulations. The Supreme People’s Court of China issued the Interpretation on theApplication of the Foreign Investment Law of the PRC on December 26, 2019, effective fromJanuary 1, 2020, to ensure fair and efficient implementation of the Foreign Investment Law.According to the judicial interpretation, courts in China shall not, among other things, supportcontracted parties to claim foreign investment contracts in sectors not on the SpecialAdministrative Measures for Access of Foreign Investment (Negative List) as void because thecontracts have not been approved or registered by administrative authorities. The ForeignInvestment Law and Implementation Regulations embody an expected PRC regulatory trend torationalize its foreign investment regulatory regime in line with prevailing internationalpractice and the legislative efforts to unify the corporate legal requirements for both foreignand domestic investments.

However, since these rules are relatively new, uncertainties still exist in relation to theirinterpretation. For instance, under the Foreign Investment Law, “foreign investment” refers tothe investment activities directly or indirectly conducted by foreign individuals, enterprises orother entities in China. Though it does not explicitly classify contractual arrangements as aform of foreign investment, there is no assurance that foreign investment via contractualarrangement would not be interpreted as a type of indirect foreign investment activities underthe definition in the future. In addition, the definition contains a catch-all provision whichincludes investments made by foreign investors through means stipulated in laws oradministrative regulations or other methods prescribed by the State Council. Therefore, it stillleaves leeway for future laws, administrative regulations or provisions promulgated by theStale Council to provide for contractual arrangements as a form of foreign investment. In anyof these cases, it will be uncertain whether our contractual arrangements will be deemed to bein violation of the market access requirements for foreign investment under the PRC laws andregulations, or whether they may be invalid in whole or in part. Furthermore, if future laws,administrative regulations or provisions prescribed by the State Council mandate furtheractions to be taken by companies with respect to existing contractual arrangements, we mayface substantial uncertainties as to whether we can complete such actions in a timely manner,or at all. Failure to take timely and appropriate measures to cope with any of these or similarregulatory compliance challenges could materially and adversely affect our current corporatestructure, corporate governance and business operations.

If the PRC government finds that the agreements establishing the structure for operatingour businesses in China do not comply with PRC regulations on foreign investment ininternet and other related businesses, or if these regulations or their interpretation changein the future, we could be subject to severe penalties or be forced to relinquish ourinterests in those operations.

Current PRC laws and regulations impose certain restrictions or prohibitions on foreignownership of companies that engage in internet and other related businesses, including theprovision of internet content and online game operations. Specifically, foreign ownership of aninternet content provider may not exceed 50%. We are a company incorporated in the CaymanIslands and Weibo Technology, our PRC subsidiary, is considered a foreign-invested enterprise.To comply with PRC laws and regulations, we conduct our business in China principallythrough Weimeng, and its subsidiaries based on a series of contractual arrangements by andamong Weibo Technology, Weimeng and its shareholders. We also operate certain investmentsin China through Beijing Weimeng Chuangke Investment Management Co., Ltd., or WeimengChuangke, and its subsidiaries, based on a series of contractual arrangements by and amongWeibo Technology, Weimeng Chuangke and its shareholders. As a result of these contractualarrangements, we exert control over Weimeng and Weimeng Chuangke and treat them asconsolidated VIEs. Consequently, we consolidate their operating results in our financialstatements under U.S. GAAP. Weimeng and Weimeng Chuangke hold certain assets that areimportant to our business operations, including the Internet Content License, the OnlineCulture Operating Permit and domain names held by Weimeng and our investments held byWeimeng Chuangke. For a detailed description of these contractual arrangements, see“Contractual Arrangements.” We conduct our operations in China through our PRCsubsidiaries and our VIEs with which we maintained these contractual arrangements. Investorsin our Class A ordinary shares or the ADSs are not purchasing equity interest in our VIEs inChina but instead are purchasing equity interest in a Cayman Islands holding company with nodirect equity ownership of our VIEs.

In the opinion of our PRC Legal Adviser, TransAsia Lawyers, our current ownership structure,the ownership structure of our PRC subsidiaries and our VIEs, and the contractualarrangements among our PRC subsidiaries, the VIEs and their respective shareholders are incompliance with existing PRC laws, rules and regulations. There are, however, substantialuncertainties regarding the interpretation and application of current or future PRC laws andregulations. Thus, we cannot assure you that the PRC government will not ultimately take aview contrary to the opinion of our PRC Legal Adviser.

Weibo Corporation, our VIEs and investors of our company face uncertainties about potentialactions by the PRC government that could affect the enforceability of the contractualarrangements with our VIEs and, consequently, the business, financial condition, and results ofoperations of our VIEs and our company as a group. It is uncertain whether any new PRC lawsor regulations relating to VIE structures will be adopted, or, if adopted, what requirementswould be made. In particular, the National People’s Congress approved the Foreign InvestmentLaw and the PRC State Council approved the Implementation Rules of Foreign Investment Lawin 2019. There are uncertainties as to how the Foreign Investment Law and its implementationrules would be further interpreted and implemented, and if it would represent a major changeto the laws and regulations relating to the VIE structures. See “— Risks Relating to DoingBusiness in the People’s Republic of China — Uncertainties exist with respect to theinterpretation and implementation of the PRC Foreign Investment Law and how it may impactthe viability of our current corporate structure, corporate governance and business operations.”If we are found in violation of any PRC laws or regulations, the relevant governmentalauthorities would have broad discretion in dealing with such violation, including, withoutlimitation, levying fines, restricting our right to collect revenues, confiscating our income or

the income of our VIEs, revoking our business licenses or the business licenses of our VIEs,requiring us to restructure our ownership structure or operations, and requiring us or our VIEsto discontinue any portion or all of our business. Any of these actions could cause significantdisruption to our business operations and may materially and adversely affect our business,financial condition and results of operations.

We rely on contractual arrangements with our VIEs and their respective shareholders forour operations in China, which may not be as effective in providing operational controlas direct ownership.

Due to the PRC restrictions or prohibitions on foreign ownership of internet and other relatedbusinesses in China, we operate our business in China through our VIEs, in which we have noownership interest. We rely on a series of contractual arrangements with our VIEs and theirrespective shareholders to control and operate their business. These contractual arrangementsare intended to provide us with effective control over these VIEs and allow us to obtaineconomic benefits from them. See “History and Corporate Structure — Corporate Structure —Contractual Arrangements” for more details about these contractual arrangements.

Although we have been advised by our PRC Legal Adviser, TransAsia Lawyers, that thesecontractual arrangements are valid, binding and enforceable under existing PRC laws andregulations, these contractual arrangements may not be as effective in providing control overthese VIEs as direct ownership. If any of these VIEs or their shareholders fail to perform theirrespective obligations under the contractual arrangements, we may incur substantial costs andexpend substantial resources to enforce our rights. All of these contractual arrangements aregoverned by and interpreted in accordance with PRC law, and disputes arising from thesecontractual arrangements will be resolved through arbitration in China. However, the legalsystem in China, particularly as it relates to arbitration proceedings, is not as developed as inother jurisdictions, such as the United States. See “Risk Factors — Risks Relating to DoingBusiness in the People’s Republic of China — Uncertainties in the interpretation andenforcement of PRC laws and regulations could limit the legal protections available to you andus.” There are very few precedents and little official guidance as to how contractualarrangements in the context of a variable interest entity (“VIE”) should be interpreted orenforced under PRC law. There remain significant uncertainties regarding the ultimate outcomeof arbitration should legal action become necessary. These uncertainties could limit our abilityto enforce these contractual arrangements. In addition, arbitration awards are final and can onlybe enforced in PRC courts through arbitration award recognition proceedings, which couldcause additional expenses and delays. In the event we are unable to enforce these contractualarrangements or we experience significant delays or other obstacles in enforcing thesecontractual arrangements, we may not be able to exert effective control over our affiliatedentities and may lose control over the assets owned by our VIEs and their subsidiaries. As aresult, we may be unable to consolidate Weimeng or Weimeng Chuangke and their respectivesubsidiaries in our consolidated financial statements, our ability to conduct our business maybe negatively affected, and our business operations could be severely disrupted, which couldmaterially and adversely affect our results of operations and financial condition.

In April 2020, WangTouTongDa (Beijing) Technology Co., Ltd., an entity affiliated withZhongWangTou (Beijing) Technology Co., Ltd, made an investment of RMB10.7 million inWeimeng for 1% of Weimeng’s enlarged registered capital. Such third party minority stakeholder is not a party to the contractual arrangements that are currently in effect amongWeimeng, Weibo Technology and Weimeng’s other shareholders. As such, despite the fact thatwe are still able to enjoy economic benefits and exercise effective control over Weimeng andits subsidiaries, we are not able to purchase or have the third party minority stake holder pledgeits 1% equity interests in Weimeng in the same manner as agreed under existing contractual

arrangements, nor are we granted the authorization of voting rights over these 1% equityinterests. However, we believe Weibo Technology, our wholly-owned PRC subsidiary, stillcontrols and is the primary beneficiary of Weimeng as it continues to have a controllingfinancial interest in Weimeng pursuant to ASC 810-10-25-38A after the issuance of such 1%equity interests.

Shareholders of our VIEs may have potential conflicts of interest with us, which mayaffect the performance of the contractual arrangements with our VIEs and theirrespective shareholders, which may in turn materially and adversely affect our businessand financial condition.

Other than the third-party minority stake holder that holds 1% of Weimeng’s equity interests,our VIEs’ shareholders (the “Individual Shareholders”) are PRC employees of our company orSINA. Although each of these Individual Shareholders has authorized Weibo Technology toexercise all of his/her voting powers in Weimeng or Weimeng Chuangke, and we may replaceany of these Individual Shareholders at any time pursuant to the share transfer agreements, wecannot assure you that these Individual Shareholders will act in the best interest of ourcompany should any conflict arise. If they were to act in bad faith towards us, we may haveto take legal actions to enforce their contractual obligations, which may be expensive,time-consuming and disruptive to our operations. As there remain significant uncertaintiesregarding the ultimate outcome of a legal action due to the limited number of precedents andlack of official guidance as to how contractual arrangements in the context of a variable interestentity should be interpreted or enforced under PRC law, we cannot assure you that conflictswill be resolved in our favor. If we are unable to resolve any such conflicts, or if we suffersignificant delays or other obstacles as a result of such conflicts, our business and operationscould be severely disrupted, which could materially and adversely affect our results ofoperations and financial condition.

We may lose the ability to use and enjoy assets held by any of our VIEs that are importantto the operation of our business if such VIE declares bankruptcy or becomes subject to adissolution or liquidation proceeding.

Our VIEs hold certain assets that are important to our business operations, including theInternet Content Provision License, the Online Culture Operating Permit and domain namesheld by Weimeng and our investments held by Weimeng Chuangke. Under our contractualarrangements with our VIEs, the Individual Shareholders may not voluntarily liquidate the VIEor approve the VIE to sell, transfer, mortgage or dispose of its assets or legal or beneficialinterests in the business in any manner without our prior consent. However, in the event thatthe Individual Shareholders breach this obligation and voluntarily liquidate any VIE, or anyVIE declares bankruptcy, or all or part of its assets become subject to liens or rights ofthird-party creditors, we may be unable to continue some or all of our business operations,which could materially and adversely affect our business, financial condition and results ofoperations. Furthermore, if any of our VIEs or their subsidiaries undergoes a voluntary orinvoluntary liquidation proceeding, their shareholders or unrelated third-party creditors mayclaim rights to some or all of their assets, thereby hindering our ability to operate our business,which could materially and adversely affect our business, financial condition and results ofoperations.

RISK FACTORS

Contractual arrangements we have entered into with our VIEs may be subject to scrutinyby the PRC tax authorities. A finding that we owe additional taxes could substantiallyreduce our consolidated net income and the value of your investment.

Pursuant to applicable PRC laws and regulations, arrangements and transactions among relatedparties may be subject to audit or challenge by the PRC tax authorities. We may be subject toadverse tax consequences if the PRC tax authorities determine that the contractualarrangements among our PRC subsidiaries, our VIEs and their Individual Shareholders are noton an arm’s length basis and therefore constitute favorable transfer pricing. As a result, thePRC tax authorities could require any of our VIEs to adjust its taxable income upward for PRCtax purposes. Such a pricing adjustment could adversely affect us by increasing such VIE’s taxexpenses without reducing the tax expenses of our PRC subsidiaries, subjecting such VIE tolate payment fees and other penalties for under-payment of taxes, and resulting in our PRCsubsidiaries’ loss of its preferential tax treatment. Our results of operations may be adverselyaffected if any of our VIEs’ tax liabilities increase or if it is subject to late payment fees orother penalties.

If the chops of our PRC subsidiaries, our VIEs and their respective subsidiaries are notkept safely, are stolen or are used by unauthorized persons or for unauthorized purposes,the corporate governance of these entities could be severely and adversely compromised.

In China, a company chop or seal serves as the legal representation of the company towardsthird parties even when unaccompanied by a signature. Each legally registered company inChina is required to maintain a company chop, which must be registered with the local PublicSecurity Bureau. In addition to this mandatory company chop, companies may have severalother chops which can be used for specific purposes. The chops of our PRC subsidiary, ourVIEs and their respective subsidiaries are generally held securely by personnel designated orapproved by us in accordance with our internal control procedures. To the extent those chopsare not kept safely, are stolen or are used by unauthorized persons or for unauthorizedpurposes, the corporate governance of these entities could be severely and adverselycompromised and those corporate entities may be bound to abide by the terms of anydocuments so chopped, even if they were chopped by an individual who lacked the requisitepower and authority to do so. In addition, if the holders of such chops at any of our VIEs failedto employ them in accordance with the terms of the various VIE-related agreements or removedthem from the premises, the operation of such VIE could be significantly and adverselyimpacted.

RISKS RELATING TO DOING BUSINESS IN THE PEOPLE’S REPUBLIC OF CHINA

Regulation and censorship of information disseminated over the internet in China mayadversely affect our business and subject us to liability for information displayed onWeibo, or Yizhibo.

The PRC government has adopted regulations governing internet access and the distribution ofinformation over the internet. Under these regulations, internet content providers and internetpublishers are prohibited from posting or displaying the internet content that, among otherthings, impairs the national dignity of China, is reactionary, obscene, superstitious, fraudulentor defamatory, or otherwise violates PRC laws and regulations. Failure to comply with theserequirements may result in the revocation of licenses to provide internet content and otherlicenses and the closure of the concerned websites and levy of fines. The website operator mayalso be held liable for such censored information displayed on or linked to the website.

RISK FACTORS

In addition, the MIIT has published regulations that subject website operators to potentialliability for content displayed on their websites and for the actions of users and others usingtheir systems, including liability for violations of PRC laws prohibiting the dissemination ofcontent deemed to be socially destabilizing. The Ministry of Public Security has the authorityto order any local internet service provider to block any internet website at its sole discretion.From time to time, the Ministry of Public Security stops the dissemination over the internet ofinformation which it believes to be socially destabilizing. The State Administration for theProtection of State Secrets is also authorized to block any website it deems to be leaking statesecrets or failing to meet the relevant regulations relating to the protection of state secrets inthe dissemination of online information. Cyberspace Administration of China, or the CAC, setup in May 2011 to supervise internet content management nationwide, has also promulgatedregulations and taken a number of other measures to regulate and monitor online content.

We endeavor to eliminate illicit content from our platform, including through the use of our“Blue Plan” system on Weibo since July 2019, and for a detailed description of the procedureswe implement, see “Business — Risk Management and Internal Control — Internal ControlRisk Management.” Although we attempt to monitor the content posted by users on Weibo andYizhibo, we are not able to effectively control or restrict content generated or placed on Weiboor Yizhibo by our users. In particular, with various features such as posts, comments and chatgroups and the growing popularity of multimedia content, such as photos, videos and livestreaming, and long-form articles, content monitoring has become much more complicated andchallenging than text-based feeds.

To the extent that PRC regulatory authorities find any content displayed on Weibo or Yizhiboobjectionable, they may require us to limit, prevent, or eliminate the dissemination of suchinformation on our platform. The CAC launched the “Clear and Bright” campaign (清朗行動)to rectify various areas of online misconduct in May 2021, in response to which, certain policeswere issued and actions were launched. On June 15, 2021, the CAC launched the “Fan GroupChaos Rectification” special action, followed by issuance of the Notice on FurtherStrengthening the Management of Chaos in Fan Groups (《關於進一步加強“飯圈”亂象治理的通知》) on August 25, 2021. Both of the special action and notice are intended to modifybehavior in the online fan groups for celebrities, specifically, in features such as celebrityrankings, hot topics, fan communities, and fans interactive functions, so as to curb verbalabuse, stigmatization, instigation, confrontation, insults, slander, rumors, malicious marketingand the spread of other harmful information. This notice requested, among other things, thecancellation of all rankings of celebrities. The rankings of music, film and television works arestill allowed, but the network platforms should optimize and adjust ranking rules to focus onthe art works themselves and to base rankings on professional evaluation. Furthermore, minorsare not allowed to make virtual gifting or spend money on supporting idols, or act as theorganizer or manager of a fan group. As of the Latest Practicable Date, we have taken measuresspecified in this notice to the extent applicable to our business, including removing thefunction of the “star power list” on our platform. In August 2021, we started to conductself-examinations and self-rectifications in response to the PRC regulatory authorities’ recentregulatory focus on financial blogs. We have identified and rectified certain for-profit bloggers,including KOLs, with inappropriate nicknames, self-descriptions, marketing events, andpublication of financial and economics related information. We have publicly disclosed therectification results on our platform, and established a hotline for users to report anyinappropriate events. During the Track Record Period, we have identified and disposed ofaround 438 million pieces of inappropriate or illegal content, via removal, blocking or othermeasures. We do not believe our rectifications have made a material adverse impact on ourbusiness. On October 26, 2021, the CAC issued the Notice on Further Strengthening theRegulation on Online Information of Entertainment Celebrities (《關於進一步加強娛樂明星網上信息規範相關工作的通知》), which requests internet platforms to, among others, monitor

RISK FACTORS

information posted by celebrities online so as to timely identify hot topics that could involveillegal actions and to promptly report to the competent authorities in such event. Failure tocomply with the requirements from PRC regulatory authorities on content regulation maysubject us to liabilities and penalties and may even result in the temporary blockage orcomplete shutdown of our online operations. During the Track Record Period, we received 43penalties for inappropriate or illegal content transmitted on our platform, and we havecooperated with the relevant government authorities to take corrective measures in all cases.For example, in June 2020, CAC imposed a fine of RMB500,000 on us for failing to timelydiscover and remove user posts violating PRC laws and regulations from our platform, andrequired us to rectify and suspend the operation of Weibo hot search feature for one week.During the Track Record Period, we have received an aggregate penalties of RMB11.3 millionfor disseminating illegal content on our platform from the relevant regulatory authorities. Webelieve these past incidents, individually or in the aggregate, did not have a material adverseeffect on our business, financial condition or results of operations during the Track RecordPeriod. In addition, the restrictions on internet content under rules and regulations promulgatedby PRC regulatory authorities may negatively impact the operation results of our livestreaming business. During the Track Record Period, we generated less than 5% of totalrevenues from live streaming business. However, government standards and interpretationsmay change in a manner that could render our current monitoring and managing effortsinsufficient. The PRC government has wide discretion in regulating online activities and,irrespective of our efforts to control the content on our platform, government campaigns andother actions to reduce inappropriate or illegal content and activities could subject us tonegative press or regulatory challenges and sanctions, including imposition of fines,suspension or revocation of our licenses to operate in China or a ban of our platform, includingclosure of one or more parts of or our entire business. If government actions or sanctions arebrought against us, or if there are widespread rumors about any actual or potential governmentactions or sanctions against us, our reputation could be harmed, we may lose users and othercustomers, and our revenues and results of operation may be materially and adversely affected.

In addition, the Judicial Interpretation on the Application of Law in Trial of Online Defamationand Other Online Crimes (《關於辦理利用信息網絡實施誹謗等刑事案件適用法律若干問題的解釋》) jointly promulgated by the Supreme People’s Court and Supreme People’sProcuratorate, which became effective on September 10, 2013, imposes up to a five-year prisonsentence on internet users who fabricate or knowingly share defamatory false informationonline. The implementation of this judicial interpretation may have a significant and adverseeffect on the traffic of our platform and discourage the creation of user-generated content,which in turn may impact the results of our operations and ultimately the trading price of ourClass A ordinary shares and/or ADSs. Regulation and censorship of information disseminatedover the internet in China may adversely affect our user experience and reduce users’engagement and activities on our platform as well as adversely affect our ability to attract newusers to our platform. Any and all of these adverse impacts may ultimately materially andadversely affect our business and results of operations.

Substantial uncertainties exist with respect to the interpretation and implementation ofcybersecurity related regulations and cybersecurity review as well as any impact thesemay have on our business operations.

The cybersecurity legal regime in China is relatively new and evolving rapidly, and theirinterpretation and enforcement involve significant uncertainties. As a result, it may be difficultto determine what actions or omissions may be deemed to be in violations of applicable lawsand regulations in certain circumstances.

Network operators in China are subject to numerous laws and regulations, and have theobligations to, among others, (i) establish internal security management systems that meet therequirements of the classified protection system for cybersecurity, (ii) implement technicalmeasures to monitor and record network operation status and cybersecurity incidents, (iii)implement data security measures such as data classification, backups and encryption, and (iv)submit for cybersecurity review under certain circumstances.

On November 7, 2016, the Standing Committee of the National People’s Congress issued theCyber Security Law (《網絡安全法》), which came into effect on June 1, 2017. Cyber SecurityLaw imposes more stringent requirements on operators of “critical information infrastructure,”especially in data storage and cross-border data transfer. See “Regulatory Overview —Regulations on Information Security.” On April 13, 2020, twelve PRC governmentalauthorities, including the CAC, issued the Measures for Cybersecurity Review (《網絡安全審查辦法》), effective from June 1, 2020, which provide detailed cybersecurity reviewprocedures for the purchase of network products and services by operators of “criticalinformation infrastructure.” Before purchasing any network products or services, an operatorof “critical information infrastructure” shall assess potential national security risks that mayarise from the launch or use of such products or services, and apply for a cybersecurity reviewwith the cybersecurity review office of CAC if national security will or may be affected.

There can be no assurance that we will not be identified as an operator of “critical informationinfrastructure.” If we are identified as an operator of “critical information infrastructure,” wewill be subject to stricter requirements on business operations and cybersecurity compliance,and we may need to follow cybersecurity review procedure and apply with CybersecurityReview Office before making certain purchases of network products and services. Duringcybersecurity review, we may be required to suspend providing any existing or new servicesto our users, and we may experience other disruptions of our operations, which could cause usto lose users and customers therefore leading to adverse impacts on our business. Thecybersecurity review could also lead to negative publicity and a diversion of time and attentionof our management and our other resources. It could be costly and time-consuming for us toprepare application materials and make the applications. Furthermore, there can be noassurance that we will obtain the clearance or approval for these applications from theCybersecurity Review Office and the relevant regulatory authorities in a timely manner, or atall. If we are found to be in violation of cybersecurity requirements in China, the relevantgovernmental authorities may, at their discretion, conduct investigations, levy fines, requestapp stores to take down our apps and cease to provide viewing and downloading servicesrelated to our apps, prohibit the registration of new users on our platform, or require us tochange our business practices in a manner materially adverse to our business. Any of theseactions could cause significant disruptions to our business operations and materially andadversely affect our business, financial condition, and results of operations.

On July 10, 2021, the CAC published a discussion draft of the proposed amended Measures forCybersecurity Review (《網絡安全審查辦法(修訂草案徵求意見稿)》), or the Draft AmendedMeasures for Cybersecurity Review, which provides that the relevant operators shall applywith the Cybersecurity Review Office for a cybersecurity review under the followingcircumstances: (i) operators of “critical information infrastructure” or data processors holdingover one million users’ personal information when listing abroad (國外上市), (ii) operators of“critical information infrastructure” that intend to purchase internet products and services thatwill or may affect national security, and (iii) data processors carrying out data processing thatwill or may affect national security. The CAC solicited comments on this draft, but there is notimetable as to when it will be enacted. As such, substantial uncertainties exist with respect toits enactment timetable, final content, interpretation and implementation. The Draft AmendedMeasures for Cybersecurity Review, if enacted as proposed, may materially impact business

operations in many aspects. As advised by our PRC Legal Adviser, the exact scope of operatorsof “critical information infrastructure” under the Draft Amended Measures for CybersecurityReview and current PRC regulatory regime remains unclear, and is subject to the decisions ofthe relevant PRC government authorities that have been delegated the authority to identifyoperators of “critical information infrastructure” in their respective jurisdictions (includingregions and industries). Those PRC government authorities have wide discretion in theinterpretation and enforcement of these laws, including the identification of operators of“critical information infrastructure” and the interpretation and enforcement of requirementspotentially applicable to such operators of “critical information infrastructure.” As a majorinternet platform, we are at risk of being deemed to be an operator of “critical informationinfrastructure” and a data processor meeting the above criteria under PRC cybersecurity laws.In such case, we would be required to fulfill various obligations as required under PRCcybersecurity laws and other applicable laws for such operators of “critical informationinfrastructure” thus currently not applicable to us, including, among others, setting up a specialsecurity management organization, organizing regular cybersecurity education and training,formulating emergency plans for cyber security incidents and conducting regular emergencydrills. In addition, although the internet products and services we purchase are primarilybandwidth, copyright content and marketing services, we cannot assure you that we will not besubject to any cybersecurity review. As of the date of this document, we have not been involvedin any investigations or cybersecurity reviews by the CAC for making those purchases ofinternet products and services during the Track Record Period, and we have not received anyinquiry, notice, warning, or sanction in such respect. If a cybersecurity review for any of ouractivities is required, we will actively cooperate with the CAC to conduct such cybersecurityreview. We have already met several key obligations currently applicable to operators of“critical information infrastructure,” including setting up a special security managementorganization, organizing regular cybersecurity education and training, formulating emergencyplans for cyber security incidents and conducting regular emergency drills, but if we aredeemed to be an operator of “critical information infrastructure” or a relevant data processor,such designation may disrupt our operations and adversely affect our business, results ofoperations and financial condition.

On November 14, 2021, the CAC published a discussion draft of the Administrative Measuresfor Internet Data Security (《網絡數據安全管理條例(徵求意見稿)》), or the Draft Measuresfor Internet Data Security, which provides that data processors conducting the followingactivities shall apply for cybersecurity review: (i) merger, reorganization or division of Internetplatform operators that have acquired a large number of data resources related to nationalsecurity, economic development or public interests affects or may affect national security; (ii)listing abroad (國外上市) of data processors processing over one million users’ personalinformation; (iii) listing in Hong Kong which affects or may affect national security; or (iv)other data processing activities that affect or may affect national security. There have been noclarifications from the authorities as of the date of this document as to the standards fordetermining such activities that “affects or may affect national security”. The CAC hassolicited comments on this draft until December 13, 2021, but there is no timetable as to whenit will be enacted. As such, substantial uncertainties exist with respect to the enactmenttimetable, final content, interpretation and implementation, including the standards fordetermining whether a listing in Hong Kong “affects or may affect national security”. TheDraft Measures for Internet Data Security, if enacted as proposed, may materially impact ourcapital raising activities. If our proposed Listing is considered a listing in Hong Kong thataffects or may affect national security, we may be required to apply for cybersecurity review,

but there can be no assurance that we are able to obtain approval from the regulatory authoritiesin a timely manner, or at all. Any failure to obtain such approval or clearance from theregulatory authorities could materially constrain our liquidity and have a material adverseimpact on our business operations and financial results, especially if we need additional capitalor financing.

The interpretation and application of these cybersecurity laws, regulations and standards arestill uncertain and evolving, especially the draft Amended Measures for Cybersecurity Reviewand the Draft Measures for Internet Data Security. We cannot assure you that relevantgovernmental authorities will not interpret or implement these and other laws or regulations inways that may negatively affect us.

We are required to, but have not been able to, verify the identities of all of our users whopost on Weibo or Yizhibo, and our noncompliance exposes us to potentially severe penaltyby the Chinese government.

The Rules on the Administration of Microblog Development (《北京市微博客發展管理若干規定》), issued by the Beijing Municipal Government in 2011, stipulate that users who postpublicly on microblogs are required to disclose their real identity to the microblogging serviceprovider, though they may still use pen names on their accounts. Microblogging serviceproviders are required to verify the identities of their users. In addition, microblogging serviceproviders based in Beijing were required to verify the identities of all of their users, includingexisting users who post publicly on their websites. Furthermore, pursuant to the Cyber SecurityLaw passed by the Standing Committee of the National People’s Congress, which came intoeffect on June 1, 2017, we will also be required to verify users’ real identities when they signup. Further, both the Administrative Measures on Group Chat Service (《互聯網群組信息服務管理規定》), which was issued on September 7, 2017 and became effective on October 8,2017, and the Administrative Measures on Internet User Public Account Information Service(《互聯網用戶公眾賬號信息服務管理規定》), which was issued on September 7, 2017 andbecame effective on October 8, 2017 and amended on January 22, 2021, require verification ofany user’s identity. On August 1, 2018, the CAC and the other five PRC governmentalauthorities jointly issued the Circular on Tightening the Administration of Online Livestreaming Services (《關於加強網絡直播服務管理工作的通知》), or the Online Livestreaming Services Circular, which specifies that online live streaming service providers arerequired to implement real name verification system for users. Several additional regulations,including the Cyber Security Law, the Administrative Measures on Group Chat Service, and theAdministrative Measures on Internet User Public Account Information Service, also requiresverification of users’ identify when they sign up.

We have made significant efforts to comply with the user verification requirements. However,for reasons including existing user behaviors, the nature of the microblogging product andonline live streaming and the lack of clarity on specific implementation procedures, we havenot been able to verify the identities of all of the users who post content publicly on Weibo orYizhibo. We are potentially liable for our noncompliance and may be subject to penaltiesincluding the deactivation of certain features on Weibo or Yizhibo, a written warning,suspension or termination of Weibo or Yizhibo operations, fines, revocation of licenses orbusiness license, or other penalties imposed by the Chinese government. Any of the aboveactions may have a material and adverse impact on the trading price of our Class A ordinaryshares and/or ADSs.

Regulatory investigations could cause us to incur additional expenses or change ourbusiness practices in a manner materially adverse to our business.

Internet content regulation in China is continuously evolving, which can at times result insustained periods of enhanced enforcement of content censorship, cyber security reviews, userprivacy compliance, and internet financial services oversight. In April 2018, relevantregulators have ordered the suspension or significant curtailment of four of China’s mostpopular news content apps as well as one of the most popular humor platforms, all inconnection with content being shared or accessed by users.

In a period of enhanced scrutiny of internet content, we may be become subject to regulatoryinvestigations or audits in connection with products or services we provide or for informationor content displayed on, retrieved from or linked to our platform, or distributed to our users.During such investigation, some or all of our products, services, features or functionalitiescould be terminated, and our Apps could be removed from relevant App stores. It is alsopossible that a regulatory investigation could result in changes to our policies or practices,could result in reputational harm, prevent us from offering certain products, services, featuresor functionalities, cause us to incur substantial costs, or require us to change our businesspractices in a manner materially adverse to our business.

We may have to register our encryption software with Chinese regulatory authorities. Ifthey request that we change our encryption software, our business operations could bedisrupted as we develop or license replacement software.

Pursuant to the Regulations for the Administration of Commercial Encryption (《商用密碼管理條例》) promulgated in 1999, foreign companies or individuals in China are required to seekapproval from the Office of the State for Cipher Code Administration, the Chinese encryptionregulatory authority, for the use of commercial encryption products or equipment involvingencryption technology. Companies operating in China are allowed to use only commercialcipher code products approved by this authority and are prohibited to use self-developed orimported cipher code products without approval. In addition, all cipher code products shall beproduced by those producers appointed and approved by this authority. Additional rulesbecame effective in 2006 and amended in 2017 regulating many aspects of commercial ciphercode products in detail, including development, production and sales.

Because these regulations do not specify what constitutes a cipher code product, we are unsureas to whether or how they apply to us and the encryption software we utilize. We may berequired to register or apply for permits for our current or future encryption software. If thePRC authorities request that we register our encryption software or change our currentencryption software to an approved cipher code product produced by an appointed producer,it could disrupt our business operations.

Regulations on virtual currency may adversely affect our game operations revenues.

We have provided Weibo Credit as an online virtual currency for users to purchase in-gamevirtual items or other types of fee-based services on our platform. In the fourth quarter of 2020,we acquired the majority equity shares of JM Tech, a company operating several onlineinteractive entertainment apps in China including “Pocket Werewolves.” JM Tech provides“gold coin” as an online virtual currency for users to purchase items to be used in those apps.The Notice on the Strengthening of Administration on Online Game Virtual Currency (《文化部 、商務部關於加強網絡遊戲虛擬貨幣管理工作的通知》), jointly issued by the Ministry ofCulture and the Ministry of Commerce in 2009, broadly defined virtual currency as a type ofvirtual exchange instrument issued by internet game operation enterprises, purchased directly

or indirectly by the game users by exchanging legal currency at a certain exchange rate, savedoutside the game programs, stored in servers provided by the internet game operationenterprises in electronic record format and represented by specific numeric units. Virtualcurrency is used to exchange internet game services provided by the issuing enterprise for adesignated extent and time, and is represented by several forms, such as online prepaid gamecards, prepaid amounts or internet game points, and does not include game props obtained fromplaying online games. In 2009, the Ministry of Culture further promulgated the FilingGuidelines on Online Game Virtual Currency Issuing Enterprises and Online Game VirtualCurrency Trading Enterprises, which specifically defines “issuing enterprise” and “tradingservice enterprise” and stipulates that a single enterprise may not operate both types ofbusiness.

Although we believe our operations are in compliance with the Notice on the Strengthening ofAdministration on Online Game Virtual Currency (《文化部 、商務部關於加強網絡遊戲虛擬貨幣管理工作的通知》), as we do not offer online game virtual currency trading services, wecannot assure you that the PRC regulatory authorities will not take a view contrary to ours, inwhich case we may be subject to fines or even required by the PRC regulators to change ourpractices related to Weibo Credit or “gold coin” in games operated by JM Tech, whichconsequently will have an adverse effect on our game-related revenues.

Adverse changes in China’s or global economic and political policies could have amaterial and adverse effect on overall economic growth in China, which could materiallyand adversely affect our business.

Substantially all of our operations are conducted in China and substantially all of our revenuesare sourced from China. Accordingly, our results of operations, financial condition andprospects are influenced by economic, political and legal developments in China. Economicreforms begun in the late 1970s have resulted in significant economic growth. However, anyeconomic reform policies or measures in China may from time to time be modified or revised.China’s economy differs from the economies of most developed countries in many respects,including the extent of the government involvement, level of development, growth rate, controlof foreign exchange and allocation of resources. The PRC government exercises significantcontrol over China’s economic growth through strategically allocating resources, controllingthe payment of foreign currency-denominated obligations, setting monetary policy andproviding preferential treatment to particular industries or companies. The PRC governmenthas significant authority to exert influence on the ability of a China-based company, such asus, to conduct its business. Therefore, investors of our company and our business face potentialuncertainties from the PRC government.

While the PRC economy has experienced significant growth in the past decades, growth hasbeen uneven across different regions and between economic sectors, and the growth rate of theChinese economy has gradually slowed since 2010, which trend may continue. Furthermore,China’s GDP growth turned negative in the first quarter of 2020. Any adverse changes ineconomic conditions in China, in the policies of the Chinese government or in the laws andregulations in China could have a material adverse effect on the overall economic growth ofChina. Such developments could adversely affect our business and operating results, lead toreduction in demand for our products and services and adversely affect our competitiveposition. The Chinese government has implemented various measures to encourage economicgrowth and guide the allocation of resources. Some of these measures may benefit the overallChinese economy, but may have a negative effect on us. For example, our financial conditionand results of operations may be adversely affected by government control over capitalinvestments or changes in tax regulations.

RISK FACTORS

COVID-19 had a severe and negative impact on the Chinese and the global economy in the firstquarter of 2020. Whether this will lead to a prolonged downturn in the economy is stillunknown. Even before the outbreak of COVID-19, the global macroeconomic environment wasfacing numerous challenges. The growth rate of the Chinese economy has gradually slowed inrecent years and the trend may continue. There is considerable uncertainty over the long-termeffects of the expansionary monetary and fiscal policies which had been adopted by the centralbanks and financial authorities of some of the world’s leading economies, including the UnitedStates and China, even before 2020. Unrest, terrorist threats and the potential for war in theMiddle East and elsewhere may increase market volatility across the globe. There have alsobeen concerns about the relationship between China and other countries, including thesurrounding Asian countries, which may potentially have economic effects. In particular, thereis significant uncertainty about the future relationship between the United States and Chinawith respect to trade policies, treaties, government regulations and tariffs. Economic conditionsin China are sensitive to global economic conditions, as well as changes in domestic economicand political policies and the expected or perceived overall economic growth rate in China. TheCOVID-19 pandemic has impacted the global and Chinese economy severely in 2020. Ourresults of operations and financial condition have been affected negatively by the spread ofCOVID-19 during the year of 2020. Any severe or prolonged slowdown in the global orChinese economy may further materially and adversely affect our business, results ofoperations and financial condition.

Uncertainties in the interpretation and enforcement of PRC laws and regulations couldlimit the legal protections available to you and us.

The PRC legal system is a civil law system based on written statutes. Unlike the common lawsystem, prior court decisions may be cited for reference but have limited precedential value.

In 1979, the PRC government began to promulgate a comprehensive system of laws andregulations governing economic matters in general. The overall effect of legislation over thepast four decades has significantly enhanced the protections afforded to various forms offoreign investments in China. However, China has not developed a fully integrated legalsystem, and recently enacted laws and regulations may not sufficiently cover all aspects ofeconomic activities in China. In particular, the interpretation and enforcement of these lawsand regulations involve uncertainties. Since PRC administrative and court authorities havesignificant discretion in interpreting and implementing statutory and contractual terms, it maybe difficult to evaluate the outcome of administrative and court proceedings and the level oflegal protection available to you and us.

Furthermore, the PRC legal system is based in part on government policies and internal rules,some of which are not published on a timely basis or at all, and which may have a retroactiveeffect. As a result, we may not be aware of our violation of any of these policies and rules untilsometime after the violation. Such uncertainties, including uncertainty over the scope andeffect of our contractual, property (including intellectual property) and procedural rights, andany failure to respond to changes in the regulatory environment in China could materially andadversely affect our business and impede our ability to continue our operations.

We face uncertainties with respect to the enactment, interpretation and implementationof Notice 78.

On November 12, 2020, the NRTA issued the Notice on Strengthening the Management ofOnline Show Live Streaming and E-commerce Live Streaming, or the Notice 78. According tothe Notice 78, platforms providing online show live streaming or e-commerce live streamingservices shall, among other things, register their information and business operations byNovember 30, 2020, ensure real-name registration for all live streaming hosts and virtualgifting users, prohibit users that are minors or without real-name registration from virtualgifting, and set a limit on the maximum amount of virtual gifting per time, per day, and permonth.

There is currently no explicit provisions as to what limits on virtual gifting will be imposed bythe NRTA pursuant to Notice 78 and it is unclear how and to what degree any such limits wouldbe imposed on different platforms. Given there is no explicit provisions on how to set the limiton virtual gifting, we are currently not able to assess the potential impact from this requirementunder Notice 78 on the virtual gifting spending activities on our platform. Any such limitsultimately imposed may negatively impact our revenues derived from virtual gifting and ourresults of operations.

Notice 78 requests the live streaming platforms for online shows and e-commerce to registerin the National Internet Audio-Visual Platforms Information Management System. Weibo hascompleted such registration, which was valid until May 1, 2021 and is currently under theannual renewal process. Notice 78 also sets forth requirements for certain live streamingbusinesses with respect to, among others, real-name registration, limits on user spending onvirtual gifting, restrictions on minors on virtual gifting, live streaming review personnelrequirements, and content tagging requirements. We have implemented real-name registrationsystem for all of our live streaming hosts and users. See “Business — Risk Management andInternal Control — Internal Control Risk Management.” For more information on Notice 78,see “Regulatory Overview — Regulations on Online Live streaming Services.”

Since Notice 78 was only issued in November 2020 and some of the requirements in Notice 78are unclear and have no explicit provisions or implementation standards, we are still in theprocess of getting further guidance from regulatory authorities and evaluating the applicabilityand effect of the various requirements under Notice 78 on our business. Any further rulemakingunder Notice 78 or other intensified regulation with respect to live streaming may increase ourcompliance burden in the live streaming business, and may have an adverse impact on ourbusiness and results of operations.

Any failure or perceived failure by us to comply with the Anti-Monopoly Guidelines forInternet Platforms Economy Sector and other PRC anti-monopoly laws and regulationsmay result in governmental investigations or enforcement actions, litigation or claimsagainst us and could have an adverse effect on our business, financial condition andresults of operations.

The PRC anti-monopoly enforcement agencies have strengthened enforcement under the PRCAnti-Monopoly Law in recent years. On December 28, 2018, the SAMR issued the Notice onAnti-monopoly Enforcement Authorization (《國家市場監督管理總局關於反壟斷執法授權的通知》), pursuant to which its province-level branches are authorized to conduct anti-monopoly enforcement within their respective jurisdictions. On September 11, 2020, theAnti-Monopoly Commission of the State Council issued Anti-monopoly Compliance Guidelinefor Operators (《經營者反壟斷合規指南》), which requires operators to establish anti-monopoly compliance management systems under the PRC Anti-Monopoly Law to manage

anti-monopoly compliance risks. On February 7, 2021, the Anti-Monopoly Commission of theState Council published Anti-Monopoly Guidelines for the Internet Platform Economy Sector(《國務院反壟斷委員會關於平台經濟領域的反壟斷指南》) that specified circumstanceswhere an activity of an internet platform will be identified as monopolistic act as well asconcentration filing procedures for business operators, including those involving variableinterest entities. On March 12, 2021, the SAMR published several administrative penalty casesabout concentration of business operators that violated PRC Anti-Monopoly Law in the internetsector. On April 13, 2021, we, together with 33 other major internet platforms in China,attended an administrative guidance meeting for Internet platform enterprises jointly convenedby the CAC, the China Taxation Administration and the SAMR. In the meeting, we wereinstructed to conduct a self-inspection within one month to focus on rectifying possibleviolation of anti-monopoly laws, such as exclusivity arrangements known as “pick one out oftwo,” abuse of dominant market position, monopolistic agreements, and the illegalconcentration of business operators, and to submit compliance commitments for publicsupervision. The rectification procedures generally include three steps: first, our company toconduct a self-examination and self-rectification and deliver a report to the relevantgovernment authority for review; second, the government authority to provide comments onthe report and guidance for our company to achieve compliance with the relevant PRC laws andregulations; and third, the government will make an inspection and confirm the rectificationresults. Weibo has initiated a self-inspection and rectification following the instructionsreceived in this meeting, and submitted a report which is currently under the review ofgovernment authority. It is still uncertain how these requirements will be implemented andwhether there will be further legislation and administration activities.

In August 2021, the SAMR issued two investigation notices to Weimeng Chuangke regardingrecent share acquisitions by Weimeng Chuangke, namely, acquisition of 68.8591% shares ofShanghai Jiamian Information Technology Co., Ltd. (上海假面信息科技有限公司) from itsexisting shareholders for the aggregate consideration of US$218.6 million and acquisition of36% shares of Jinhua Ruian Investment Management Co., Ltd. (金華睿安投資管理有限公司),the holding entity of Shanghai Benqu Network Technology Co., Ltd., a developer of Wutabeauty camera app, from its existing shareholders for the aggregate consideration of US$41.7million, in respect of potential illegal concentration of business operators under theAnti-Monopoly Law. Both acquisitions reached the threshold for a prior-filing under theProvisions of the State Council on the Threshold for the Reporting of Concentration ofBusiness Operators (國務院關於經營者集中申報標准的規定) but Weimeng Chuangke did notmake the filing before the consummation of these transactions.

On November 16, 2021, the SAMR issued a decision of administrative penalty to WeimengChuangke with a fine of RMB500,000 based on the determination that Weimeng Chuangke’sshare acquisition of Jinhua Ruian Investment Management Co., Ltd. (金華睿安投資管理有限公司) constituted a concentration of business operators without prior filing pursuant to theAnti-Monopoly Law (中華人民共和國反壟斷法). Weimeng Chuangke will timely pay the fineas required by such decision of administrative penalty.

As of the date of this document, the investigation into the share acquisition of ShanghaiJiamian Information Technology Co., Ltd. (上海假面信息科技有限公司), or JM Tech, isongoing and Weimeng Chuangke is actively cooperating with the SAMR. We are not able topredict the status or the results of the investigation at this stage. According to the PRCAnti-Monopoly Law (中華人民共和國反壟斷法), if a business operator carries out aconcentration in violation of the law, the relevant authority shall order the business operatorto terminate the concentration, dispose of the shares or assets or transfer the business within

a specified time limit, or take other measures to restore the pre-concentration status, and mayimpose a fine of up to RMB500,000. As such, our PRC legal adviser is of the view that wecould be subject to fines of up to RMB500,000 and other legal actions disclosed above for suchshare acquisition, which however would not have a material adverse effect on our businesssince JM Tech contributed US$11.5 million of revenues and US$7.2 million of net income tothe Group in 2020. On October 23, 2021, the Standing Committee of the National People’sCongress issued a discussion draft of the amended Anti-Monopoly Law, which proposes toincrease the fines for illegal concentration of business operators to “no more than ten percentof its last year’s sales revenue if the concentration of business operator has or may have aneffect of excluding or limiting competition; or a fine of up to RMB5 million if theconcentration of business operator does not have an effect of excluding or limitingcompetition.” The draft also proposes for the relevant authority to investigate transactionwhere there is evidence that the concentration has or may have the effect of eliminating orrestricting competition, even if such concentration does not reach the filing threshold.

We are of the view that (i) the strengthened enforcement of the Anti-Monopoly Law couldresult in investigations on our acquisition transactions conducted in the past and make ouracquisition transactions in the future more difficult due to the prior filing requirement; (ii)although we do not expect that the PRC anti-monopoly laws will materially and adverselyaffect our business, it may increase our compliance burden, particularly in the context ofrelevant PRC authorities recently strengthening supervision and enforcement of the Anti-Monopoly Law against internet platforms; given that we do not hold a dominant marketposition in the relevant markets and we have not entered into any monopolistic agreement, ourPRC legal adviser is of the view that, except for our acquisitions that are under investigationfor concentration of business operators, we are in compliance with the currently effective PRCanti-monopoly laws in all material aspects; however, if the PRC regulatory authorities identifyany of our activities as monopolistic under the PRC Anti-Monopoly Law or the Anti-MonopolyGuidelines for the Internet Platform Economy Sector, or identify us holding a dominant marketposition or of abusing such dominant position, we may be subject to other investigations andadministrative penalties, such as termination of monopolistic act and confiscation of illegalgains; and (iii) there are significant uncertainties associated with the evolving legislativeactivities and varied local implementation practices of anti-monopoly and competition lawsand regulations in China, especially with respect to the enactment timetable, final content,interpretation and implementation of the amended Anti-Monopoly Law. If it is enacted asproposed, it will be more difficult to complete the acquisition transaction. It will be costly forus to adjust our business practices in order to comply with these evolving laws, regulations,rules, guidelines and implementations. Any non-compliance or associated inquiries,investigations and other governmental actions may divert significant management time andattention and our financial resources, lead to negative publicity, liabilities or administrativepenalties, therefore materially and adversely affect our financial conditions, operations andbusiness prospects. If we are required to take any rectifying or remedial measures or are subjectto any penalties, our reputation and business operations may be materially and adverselyaffected.

We may be adversely affected by the complexity, uncertainties and changes in PRClicensing and regulation of internet businesses.

The PRC government extensively regulates the internet industry, including the licensing andpermit requirements pertaining to companies in this industry. Internet-related laws andregulations in China are relatively new and evolving, and their interpretation and enforcementinvolve significant uncertainty. As a result, it may be difficult to determine what actions oromissions may be deemed to be violations of applicable laws and regulations in certaincircumstances.

Weimeng holds an Internet Content Provision License and an Online Culture Operating Permitthat are necessary for operating our current business in China. Weimeng also holds aninter-regional Value-Added Telecommunications Services Operating License for provision ofvalue-added telecommunication services nationwide. However, we cannot assure you that wehave obtained all the permits or licenses required for conducting our business in China or willbe able to maintain our existing licenses or obtain any new licenses if required by any new lawsor regulations. Companies engaging in internet broadcasting activities, such as the Yizhibo livestreaming business we acquired in October 2018, must first obtain an audio/video programtransmission license. See “Regulatory Overview — Regulations on Broadcasting Audio/VideoPrograms through the Internet” for more details. Weimeng is not qualified to obtain the internetaudio/video program transmission license under the current legal regime as it is not a whollystate-owned or state-controlled company and it was not operating prior to the issuance of theRules for the Administration of Internet Audio and Video Program Services, commonly knownas Circular 56. Weimeng plans to apply for an internet audio/video program transmissionlicense when feasible to do so. In June 2017, the State Administration of Press, Publication,Radio, Film and Television of the People’s Republic of China issued a public notice stating thatit had requested the local competent authorities to take measures to suspend several companies’video and audio services due to their lacking of an internet audio/video program transmissionlicense and posting of certain commentary programs with content in violation of governmentregulations on their sites, and Weibo is named as one of these companies. In 2018 and 2019,Beijing Integrated Law Enforcement on the Cultural Market issued three decisions onadministrative penalties to Weimeng, each of which imposed a warning and a fine ofRMB30,000 on Weimeng on the grounds that Weimeng carried on internet audio/video programservices without obtaining the internet audio/video program transmission license and providedonline broadcasting services for relevant programs posted by certain registered users of Weibo.We have cooperated with the relevant government authorities to take corrective measures,including, among other measures, immediate removal of relevant audio/video programming,warning or banning live streaming hosts, and improving our ability to identify and interceptillegal content. We have registered with the National Internet Audio-Visual PlatformsInformation Management System, through which our operations is supervised and guided bythe National Radio and Television Administration and its local branches. This registration wasvalid until May 1, 2021 and is currently under the annual renewal process. However, there canbe no assurance that there will not be any further enforcement action, the occurrence of whichmay result in further liabilities, penalties and operational disruption. In addition, we may berequired to obtain an internet publishing permit due to the online game related services weprovided and the contents generated by our users. See “Regulatory Overview — Regulations onOnline Game Operations and Cultural Products.” Weimeng has been actively communicatingwith the relevant regulator for the application of an internet publishing permit. Weimeng maynot be able to obtain such license due to inappropriate or illegal content generated by users.Before we obtain such licenses or any additional licenses required by new laws and regulations,we could be subject to liabilities and penalties for providing online publishing services withoutthe relevant licenses, including removal of the relevant online publications, confiscation ofillegal income, fines, and/or the closure of our relevant websites, which could lead to severedisruption to our business operation.

Foreign investment in online game operation is prohibited under PRC law. We currentlyprovide our online game services through Weimeng, Weibo Interactive and WeimengChuangke’s subsidiaries. However, certain contracts relating to our online game services wereentered into between our PRC subsidiaries, Weimeng and the game developers, under whichour PRC subsidiaries, together with Weimeng, provides certain technical services through ourwebsite. Under these agreements, our PRC subsidiaries, foreign-invested enterprises, may bedeemed to be providing value-added telecommunication services without the necessarylicenses. If so, we may be subject to sanctions, including payment of delinquent taxes andfines, which may significantly disrupt our operations and materially and adversely affect ourbusiness, results of operations and financial condition.

Furthermore, the operation of online games in China is highly regulated by the PRCgovernment. The publication of a new online game or a significant upgrade of an existingonline game requires approval from the National Press and Publication Administration, or theNPPA. There are uncertainties with respect to the interpretation and implementation of the lawsand regulations governing online games. Although most of the games on our website haveobtained approval from the NPPA, certain games may not be able to obtain such approval dueto the narrow interpretation of the scope of “game” adopted by NPPA in practice. For example,“Pocket Werewolves” operated by JM Tech may not be able to obtain the approval from NPPAas it is considered a social app instead of a game app. If any online game operated on ourplatform or by JM Tech fails to timely obtain necessary regulatory approval, the operator of therelevant game may be subject to various penalties and the operation of the relevant game couldbe suspended or discontinued, which could adversely affect our business. The InterimMeasures for the Administration of Online Games (《網絡遊戲管理暫行辦法》) that wasissued by the Ministry of Culture, on June 3, 2010, and last amended on December 15, 2017,comprehensively regulated the activities related to online game business until July 10, 2019when it was abolished by the Culture and Tourism of the PRC according to the Decision onAbolishing the Interim Measures for the Administration of Online Games and the Measures forthe Administration of Tourism Development Planning. As of the Latest Practicable Date, thegovernmental authorities have not issued laws or regulations to replace the Interim Measureson Administration of Online Games.

In addition, due to the increasing popularity and use of the internet, online games and otheronline services, it is possible that additional laws and regulations may be adopted with respectto the internet, online games or other online services covering issues such as user privacy,pricing, content, copyrights and distribution. The adoption of additional laws or regulationsmay decrease the growth of the internet, online games or other online services, which could inturn decrease the demand for our products and services and increase our cost of doing business.

If the game publishers and operators fail to maintain the normal publication and operation oftheir online games, or if they fail to complete or obtain the necessary approvals of their onlinegames, our operations may be negatively impacted, and we may be subject to penalties for livestreaming such games.

Furthermore, the PRC government has taken steps to limit the method and manner that theinternet companies may apply when using the algorithms. For instance, the CAC, together witheight other governmental authorities, jointly issued the Guidelines on Strengthening theComprehensive Regulation of Algorithms for Internet Information Services (關於加強互聯網信息服務算法綜合治理的指導意見) on September 17, 2021, which provides that dailymonitoring of data use, application scenarios and effects of algorithms shall be carried out bythe relevant regulators, and security assessments of algorithms shall be conducted by therelevant regulators. The guidelines also provide that an algorithm filing system shall beestablished, and classified security management of algorithms shall be promoted. In addition,the Cyberspace Administration of China issued a discussion draft of Administrative Provisionson Algorithm Recommendation of Internet Information Services (互聯網信息服務算法推薦管理規定(徵求意見稿)) on 27 August 2021, which provides that algorithms recommendationservice providers are not allowed to use algorithms to register false user accounts, blockinformation, give excessive recommendations, and that users should be given the option toeasily turn off algorithm recommendation services. Although the CAC has solicited commentson this draft since August 27, 2021, there is no timetable as to when it will be enacted. As such,substantial uncertainties exist with respect to its enactment timetable, final content,interpretation and implementation. Our social interest graph recommendation engine, whichleverages our database of users’ social interest graphs based on their engagement actions on ourplatform, allows us to push the content that the users may find more relevant and interesting.

If the draft of the Administrative Provisions on Algorithm Recommendation of InternetInformation Services is enacted as proposed, we may need to further adjust our business andoperations. For instance, under this draft, algorithms recommendation service providers arerequired to publicly disclose the basic principles, purposes, intention, and operatingmechanism of our algorithm-related products. In response to this draft, we have publiclydisclosed the operation mechanism for “Weibo hot search” and provided an option for our usersto limit algorithm-driven recommendations for content and advertisements in certain ways.However, the impact on our business operations is still substantially uncertain since the draftis not yet enacted. In the event the draft is eventually enacted, the impact on our SIGrecommendation engine still depends largely on the number of users who actually turn off ouralgorithm recommendation services. If such opt-out ratio turns out to be on the high end, theadvertisement efficiency on our platform may ultimately be lowered and our businessoperations may be adversely affected.

PRC regulations of loans to PRC entities and direct investment in PRC entities byoffshore holding companies may delay or prevent us from using offshore funds to makeloans or additional capital contributions to our PRC subsidiaries.

We may transfer funds to our PRC subsidiaries or finance our PRC subsidiaries by means ofshareholder loans or capital contributions. Any loans from us to our PRC subsidiaries, whichis a foreign-invested enterprise, cannot exceed statutory limits based on the difference betweenthe registered capital and the investment amount of such subsidiaries or 200% of its net assets,and shall be registered with the State Administration of Foreign Exchange, or SAFE, or itslocal counterparts. Any capital contributions we make to our PRC subsidiaries is subject to therequirement of necessary filings in the Foreign Investment Comprehensive ManagementInformation System and registration with other governmental authorities. We may not be ableto obtain these government registrations or approvals on a timely basis, if at all. If we fail toreceive such registrations or approvals, our ability to provide loans or capital contributions toour PRC subsidiaries in a timely manner may be negatively affected, which could materiallyand adversely affect our liquidity and our ability to fund and expand our business.

On March 30, 2015, SAFE issued the Circular on Reform of the Administrative Rules of thePayment and Settlement of Foreign Exchange Capital of Foreign-Invested Enterprises (《國家外匯管理局關於改革外商投資企業外匯資本金結匯管理方式的通知》), or SAFE Circular 19,which became effective on June 1, 2015. SAFE Circular 19 adopts a concept of “discretionaryconversion,” which is defined as the conversion of a foreign-invested enterprise’s foreigncurrency registered capital in accordance with the enterprise’s actual business needs. Noreview of the purpose of the funds is required at the time of conversion under SAFECircular 19. However, use of any RMB funds converted from its registered capital shall bebased on true transactions. In addition, equity investments using converted registered capitalare no longer prohibited under SAFE Circular 19.

SAFE issued the Circular on Reforming and Regulating Policies on the Control over ForeignExchange Settlement of Capital Accounts (《國家外匯管理局關於改革和規範資本項目結匯管理政策的通知》), or SAFE Circular 16, on June 9, 2016, which became effective on the sameday. Pursuant to SAFE Circular 16, enterprises registered in the PRC may also convert theirforeign debts from foreign currency to RMB on self-discretionary basis. SAFE Circular 16provides an integrated standard for conversion of foreign exchange under capital account items(including but not limited to foreign currency capital and foreign debts) on self-discretionarybasis which applies to all enterprises registered in the PRC. SAFE Circular 16 reiterates theprinciple that RMB converted from foreign currency-denominated capital of a company maynot be directly or indirectly used for purposes beyond its business scope or prohibited by PRC

Violations of SAFE Circular 19 and SAFE Circular 16 could result in administrative penalties.SAFE Circular 19 and SAFE Circular 16 may significantly limit our ability to transfer anyforeign currency we hold, including the net proceeds from our equity offering and notesoffering, to our PRC subsidiaries, which may adversely affect our liquidity and our ability tofund and expand our business in China.

On October 23, 2019, SAFE issued the Notice of the State Administration of Foreign Exchangeon Further Promoting the Facilitation of Cross-border Trade and Investment (《國家外匯管理局關於進一步促進跨境貿易投資便利化的通知》), or SAFE Circular 28. SAFE Circular 28allows non-investment foreign-invested enterprises to use their capital funds to make equityinvestments in China, provided that such investments do not violate the Negative List and thatthe target investment projects are genuine and in compliance with PRC laws.

In light of the various requirements imposed by PRC regulations on loans to and directinvestment in PRC entities by offshore holding companies, we cannot assure you that we willbe able to complete the necessary government registrations or obtain the necessary governmentapprovals on a timely basis, if at all, with respect to future loans by us to our PRC subsidiariesor with respect to future capital contributions by us to our PRC subsidiaries. If we fail tocomplete such registrations or obtain such approvals, our ability to use the proceeds wereceived from our equity offering and notes offering and to capitalize or otherwise fund ourPRC operations may be negatively affected, which could materially and adversely affect ourliquidity and our ability to fund and expand our business.

We may be subject to penalties, including restriction on our ability to inject capital intoour PRC subsidiaries and our PRC subsidiaries’ ability to distribute profits to us, if ourPRC resident shareholders beneficial owners fail to comply with relevant PRC foreignexchange rules.

The SAFE promulgated the Circular on Relevant Issues Relating to Domestic Resident’sInvestment and Financing and Roundtrip Investment through Special Purpose Vehicles (《國家外匯管理局關於境內居民通過特殊目的公司境外投融資及返程投資外匯管理有關問題的通知》), or SAFE Circular 37, in July 2014 that requires PRC residents or entities to register withSAFE or its local branch in connection with their establishment or control of an offshore entityestablished for the purpose of overseas investment or financing. In addition, such PRCresidents or entities must update their SAFE registrations when the offshore special purposevehicle undergoes material events relating to any change of basic information (includingchange of such PRC citizens or residents, name and operation term), increases or decreases ininvestment amount, transfers or exchanges of shares, or mergers or divisions.

SAFE Circular 37 is issued to replace the Notice on Relevant Issues Concerning ForeignExchange Administration for PRC Residents Engaging in Financing and Roundtrip Investmentsvia Overseas Special Purpose Vehicles (《國家外匯管理局關於境內居民通過境外特殊目的公司融資及返程投資外匯管理有關問題的通知》), or SAFE Circular 75.

If our shareholders who are PRC residents or entities do not complete their registration withthe local SAFE branches, our PRC subsidiaries may be prohibited from distributing theirprofits and proceeds from any reduction in capital, share transfer or liquidation to us, and wemay be restricted in our ability to contribute additional capital to our PRC subsidiaries.Moreover, failure to comply with the SAFE registration described above could result inliability under PRC laws for evasion of applicable foreign exchange restrictions.

We have requested all of our current shareholders and/or beneficial owners to disclose whetherthey or their shareholders or beneficial owners fall within the ambit of Circular 37 and haveurged relevant shareholders and beneficial owners, upon learning they are PRC residents, toregister with the local SAFE branch as required under Circular 37. However, we may not beinformed of the identities of all the PRC residents or entities holding direct or indirect interestin our company, nor can we compel our beneficial owners to comply with SAFE registrationrequirements. As a result, we cannot assure you that all of our shareholders or beneficialowners who are PRC residents or entities have complied with, and will in the future make orobtain any applicable registrations or approvals required by, SAFE regulations. Failure by suchshareholders or beneficial owners to comply with SAFE regulations, or failure by us to amendthe foreign exchange registrations of our PRC subsidiaries, could subject us to fines or legalsanctions, restrict our overseas or cross-border investment activities, limit our PRCsubsidiaries’ ability to make distributions or pay dividends to us or affect our ownershipstructure, which could adversely affect our business and prospects.

We and/or our Hong Kong subsidiary may be classified as a “PRC resident enterprise” forPRC enterprise income tax purposes. Such classification would likely result inunfavorable tax consequences to us and our non-PRC shareholders and have a materialadverse effect on our results of operations and the value of your investment.

The Enterprise Income Tax Law (《中華人民共和國企業所得稅法》) provides that anenterprise established outside China or established pursuant to foreign (regional) laws whose“de facto management body” is located in China is considered a “PRC resident enterprise” andwill generally be subject to the uniform 25% enterprise income tax on its global income. Underthe Implementation Rules of the Enterprise Income Tax Law, “de facto management body” isdefined as the organizational body which substantially and comprehensively manages andcontrols the production and operation, personnel, accounting and properties of an enterprise.

Pursuant to the Notice Regarding the Determination of Chinese-Controlled OffshoreIncorporated Enterprises as PRC Tax Resident Enterprises on the Basis of De FactoManagement Bodies (《關於境外註冊中資控股企業依據實際管理機構標準認定為居民企業有關問題的通知》), issued by the State Administration of Taxation in 2009, a foreign enterprisecontrolled by PRC enterprises or PRC enterprise groups is considered a PRC residententerprise if all of the following conditions are met: (i) the senior management and coremanagement departments in charge of daily operations are located mainly within the PRC;(ii) financial and human resources decisions are subject to determination or approval bypersons or bodies in the PRC; (iii) major assets, accounting books, company seals and minutesand files of board and shareholders’ meetings are located or kept within the PRC; and (iv) atleast half of the enterprise’s directors with voting rights or senior management often residewithin the PRC. Although the notice states that these standards only apply to offshoreenterprises that are controlled by PRC enterprises or PRC enterprise groups, such standardsmay reflect the general view of the State Administration of Taxation in determining the taxresidence of foreign enterprises.

RISK FACTORS

– 100 –

We believe that neither our company nor our Hong Kong subsidiary is a PRC residententerprise because neither our company nor our Hong Kong subsidiary meets all of theconditions enumerated. For example, board and shareholders’ resolutions of our company andour Hong Kong subsidiary are adopted in Hong Kong and the minutes and related files are keptin Hong Kong. However, if the PRC tax authorities were to disagree with our position, ourcompany and/or our Hong Kong subsidiary may be subject to PRC enterprise income taxreporting obligations and to a 25% enterprise income tax on our global taxable income, exceptfor our income from dividends received from our PRC subsidiary, which may be exempt fromPRC tax. If we and/or our Hong Kong subsidiary are treated as a PRC resident enterprise, the25% enterprise income tax may adversely affect our ability to satisfy any of our cash needs.

In addition, if we were to be classified as a PRC “resident enterprise” for PRC enterpriseincome tax purpose, dividends we pay to our non-PRC enterprise shareholders and gainsderived by our non-PRC enterprise shareholders from the sale of our shares and ADSs may bebecome subject to a 10% PRC withholding tax. In addition, future guidance may extend thewithholding tax to dividends we pay to our non-PRC individual shareholders and gains derivedby such shareholders from transferring our shares and ADSs. In addition to the uncertainty inhow the “resident enterprise” classification could apply, it is also possible that the rules maychange in the future, possibly with retroactive effect. If PRC income tax were imposed on gainsrealized through the transfer of our ADSs or ordinary shares or on dividends paid to ournon-resident shareholders, the value of your investment in our ADSs or ordinary shares maybe materially and adversely affected.

Any limitation on the ability of our PRC subsidiaries to make payments to us, or the taximplications of making payments to us, could have a material adverse effect on our abilityto conduct our business or our financial condition.

We are a holding company, and we rely principally on dividends and other distributions fromour PRC subsidiaries for our cash needs, including the funds necessary to pay dividends to ourshareholders or service any debt we may incur. Current PRC regulations permit our PRCsubsidiaries to pay dividends only out of its accumulated profits, if any, determined inaccordance with PRC accounting standards and regulations. In addition, our PRC subsidiariesare required to set aside at least 10% of its after-tax profits each year, if any, to fund certainstatutory reserve funds until the aggregate amount of such reserve funds reaches 50% of itsregistered capital. Apart from these reserves, our PRC subsidiaries may allocate discretionaryportion of their after-tax profits to staff welfare and bonus funds at their discretion. Thesereserves and funds are not distributable as cash dividends. Furthermore, if our PRC subsidiariesincur debt, the debt instruments may restrict its ability to pay dividends or make otherpayments to us. We cannot assure you that our PRC subsidiaries will generate sufficientearnings and cash flows in the near future to pay dividends or otherwise distribute sufficientfunds to enable us to meet our obligations, pay interest and expenses or declare dividends.

Distributions made by PRC companies to their offshore parents are generally subject to a 10%withholding tax under the Enterprise Income Tax Law. Pursuant to the Enterprise Income TaxLaw and the Arrangement between the Mainland of China and the Hong Kong SpecialAdministrative Region for the Avoidance of Double Taxation and the Prevention of FiscalEvasion with respect to Taxes on Income, the withholding tax rate on dividends paid by ourPRC subsidiaries to our Hong Kong subsidiary would generally be reduced to 5%, providedthat our Hong Kong subsidiary is the beneficial owner of the PRC sourced income. Further, theState Taxation Administration promulgated the Announcement of the Certain Issues withRespect to the “Beneficial Owner” in Tax Treaties (《國家稅務總局關於稅收協定中“受益所有人”有關問題的公告》) in 2018, which sets forth certain detailed factors in determining

RISK FACTORS

– 101 –

“beneficial owner” status, and specifically, if an applicant’s business activities do notconstitute substantive business activities, the applicant will not qualify as a “beneficial owner”.Although our PRC subsidiary is wholly owned by our Hong Kong subsidiary, we will not beable to enjoy the 5% withholding tax rate with respect to any dividends or distributions madeby our PRC subsidiary to its parent company in Hong Kong if our Hong Kong subsidiary is notregarded as a “beneficial owner.”

In addition, if Weibo HK were deemed to be a PRC resident enterprise, then dividends payableby Weibo HK to Weibo Corporation may become subject to 10% PRC dividend withholdingtax. Under such circumstances, it is not clear whether dividends payable by Weibo Technologyto Weibo Corporation would still be subject to PRC dividend withholding tax and whether suchtax, if imposed, would be imposed at a rate of 5% or 10%.

Restrictions on the remittance of RMB into and out of China and governmental controlof currency conversion may limit our ability to pay dividends and other obligations, andaffect the value of your investment.

The PRC government imposes controls on the convertibility of the RMB into foreigncurrencies and the remittance of currency out of China. We receive substantially all of ourrevenues in RMB and the majority of our cash inflows and outflows are denominated in RMB.Under our current corporate structure, our cash needs are dependent on dividend paymentsfrom our subsidiaries in China after it receives payments from our VIEs under various servicesand other contractual arrangements. We may convert a portion of our RMB into othercurrencies to meet our foreign currency obligations, such as payments of dividends declared inrespect of our ordinary shares, if any. Shortages in the availability of foreign currency mayrestrict the ability of our PRC subsidiaries to remit sufficient foreign currency to pay dividendsor other payments to us, or otherwise satisfy its foreign currency denominated obligations.

Under existing PRC foreign exchange regulations, payments of current account items,including profit distributions, interest payments and trade and service-related foreign exchangetransactions, can be made in foreign currencies without prior SAFE approval as long as certainroutine procedural requirements are fulfilled. Therefore, our PRC subsidiaries is allowed to paydividends in foreign currencies to us without prior SAFE approval by following certain routineprocedural requirements. However, approval from or registration with competent governmentauthorities is required where the RMB is to be converted into foreign currency and remitted outof China to pay capital expenses such as the repayment of loans denominated in foreigncurrencies. The PRC government may at its discretion restrict access to foreign currencies forcurrent account transactions in the future. If the foreign exchange control system prevents usfrom obtaining sufficient foreign currencies to satisfy our foreign currency demands, we maynot be able to pay dividends in foreign currencies to our shareholders, including holders of ourClass A ordinary shares and/or ADSs.

Discontinuation of preferential tax treatment or imposition of any additional taxes couldadversely affect our financial condition and results of operations.

The Enterprise Income Tax Law and its implementing rules have adopted a uniform statutoryenterprise income tax rate of 25% to all enterprises in China. The Enterprise Income Tax Lawand its implementing rules also permit qualified “software enterprises” to enjoy a two-yearincome tax exemption starting from the first profit making year, followed by a reduced tax rateof 12.5% for the subsequent three years. In addition, qualified “key software enterprises” canenjoy a reduced tax rate of 10%. Weibo Technology, our PRC subsidiary, was qualified as a“software enterprise” on December 19, 2011, the qualification of which was renewed each year.

RISK FACTORS

– 102 –

Accordingly, Weibo Technology is eligible for the relevant preferential tax treatment uponfiling with the relevant tax authorities. Its qualification as a “software enterprise” is subject toannual evaluation by the relevant authorities in China. Weibo Technology, a qualified softwareenterprise, enjoyed the relevant tax holiday from its first accumulative profitable year in 2015and was subject to a reduced enterprise income tax rate of 12.5% from 2017 to 2019. AlthoughWeibo Technology was qualified as a “software enterprise” in 2020, it will not enjoy a reducedtax rate as it has been five years since it first became profitable in 2015. Weibo Technologycompleted its filings as a “key software enterprise” with the tax authority in 2018, 2019 and2020 for its status of 2017, 2018 and 2019, therefore is entitled to enjoy a further reducedpreferential tax rate of 10% for 2017, 2018 and 2019. The qualification as a “key softwareenterprise” is subject to annual evaluation and approval by the relevant authorities in China andwe will only recognize the preferential tax treatment of “key software enterprise” status whenapproval from the relevant authorities is obtained, usually one year in arrears. On February 7,2021, the NDRC published the Circular on the Requirements for the Formulation of the Listof Integrated Circuit Enterprises or Project and Software Enterprises Enjoying Tax Preferences(《關於印發享受稅收優惠的集成電路企業或項目、軟件企業清單制定有關要求的通知(徵求意見稿)》) for the public comment by March 8, 2021, which provides higher requirements on“key software enterprise” than before. If Weibo Technology fails to maintain its “key softwareenterprise” qualification, its applicable corporate income tax rate would increase to 25%,which could have an adverse effect on our financial condition and results of operations.

Furthermore, certain enterprises may still benefit from a preferential tax rate of 15% under theEnterprise Income Tax Law and its implementing rules if they qualify as a “High and NewTechnology Enterprise” subject to certain general factors described in the Enterprise IncomeTax Law and the related regulations. Weibo Technology is qualified as a High and NewTechnology Enterprise and is entitled to a preferential tax rate of 15% for the fiscal years from2017 to 2022. Its qualification as a “High and New Technology Enterprise” is subject to annualevaluation and a three-year review by the relevant authorities in China. If Weibo Technologyfails to maintain its “High and New Technology Enterprise” qualification, its applicablecorporate income tax rate would increase to 25%, which could have an adverse effect on ourfinancial condition and results of operations.

Moreover, there are also news articles reporting that the PRC government may charge data taxin the future potentially by having tech giants that possess huge amount of personal data returnportions of their revenues generated by transactions to owners of the data, which may in turnhave an adverse effect on our business or financial conditions.

Failure to comply with PRC regulations regarding the registration requirements for stockownership plans or stock option plans may subject PRC plan participants or us to finesand other legal or administrative sanctions.

In February 2012, SAFE promulgated the Notices on Issues concerning the Foreign ExchangeAdministration for Domestic Individuals Participating in Stock Incentive Plan of OverseasPublicly Listed Company (《關於境內個人參與境外上市公司股權激勵計劃外匯管理有關問題的通知》), or the Stock Option Rule, replacing the earlier rules promulgated in March 2007and January 2008. Under the Stock Option Rule, PRC residents who participate in an employeestock ownership plan or stock option plan in an overseas publicly listed company are requiredto register with SAFE or its local branch and complete certain other procedures. Participantsof a stock incentive plan who are PRC residents must retain a qualified PRC agent, which couldbe a PRC subsidiary of such overseas publicly listed company, to conduct the SAFEregistration and other procedures with respect to the stock incentive plan on behalf of theseparticipants. Such participants must also retain an overseas entrusted institution to handlematters in connection with their exercise or sale of stock options. In addition, the PRC agentis required to amend the SAFE registration with respect to the stock incentive plan if there isany material change to the stock incentive plan, the PRC agent or the overseas entrustedinstitution or other material changes.

We and our PRC resident employees who participate in our share incentive plans have beensubject to these regulations since our company became publicly listed in the United States. Ifwe or our PRC resident employees who participate in our share incentive plans fail to complywith these regulations in the future, we or our PRC resident employees who participate in ourshare incentive plans and their local employers may be subject to fines and legal sanctions.

Fluctuation in the value of the RMB may have a material adverse effect on the value ofyour investment.

The conversion of Renminbi into foreign currencies, including U.S. dollars, is based on ratesset by the People’s Bank of China. The value of Renminbi against the U.S. dollar and othercurrencies is affected by changes in China’s political and economic conditions and by China’sforeign exchange policies, among other things. We cannot assure you that Renminbi will notappreciate or depreciate significantly in value against the U.S. dollar in the future. It is difficultto predict how market forces or PRC or U.S. government policy may impact the exchange ratebetween Renminbi and the U.S. dollar in the future.

Our revenues and costs are mostly denominated in RMB, and a significant portion of ourfinancial assets are also denominated in RMB, whereas our reporting currency is the U.S.dollar. Any significant depreciation of the RMB may materially and adversely affect ourrevenues, earnings and financial position as reported in U.S. dollars. To the extent that we needto convert U.S. dollars we received from offerings or debt financing into RMB for ouroperations, appreciation of the RMB against the U.S. dollar would have an adverse effect onthe RMB amount we would receive from the conversion. Conversely, if we decide to convertour RMB into U.S. dollars for the purpose of making payments for dividends on our ordinaryshares or ADSs or for other business purposes, appreciation of the U.S. dollar against the RMBwould have a negative effect on the U.S. dollar amount available to us.

PRC laws and regulations establish more complex procedures for some acquisitions ofChinese companies by foreign investors, which could make it more difficult for us topursue growth through acquisitions in China.

A number of PRC laws and regulations, including the Regulations on Mergers and Acquisitionsof Domestic Enterprises by Foreign Investors (《關於外國投資者併購境內企業的規定》)adopted by six PRC regulatory agencies in 2006 and last amended in 2009, or the M&A Rules,the Anti-Monopoly Law (《中華人民共和國反壟斷法》), and the Rules of Ministry ofCommerce on Implementation of Security Review System of Mergers and Acquisitions ofDomestic Enterprises by Foreign Investors (《商務部實施外國投資者併購境內企業安全審查制度的規定》) promulgated by the Ministry of Commerce in August 2011, or the SecurityReview Rules, have established procedures and requirements that are expected to make mergerand acquisition activities in China by foreign investors more time consuming and complex.These include requirements in some instances that the Ministry of Commerce be notified inadvance of any change of control transaction in which a foreign investor takes control of a PRCdomestic enterprise, or that the approval from the Ministry of Commerce be obtained incircumstances where overseas companies established or controlled by PRC enterprises orresidents acquire affiliated domestic companies. PRC laws and regulations also require certainmerger and acquisition transactions to be subject to merger control review or security review.

RISK FACTORS

– 104 –

The Security Review Rules were formulated to implement the Notice of the General Office ofthe State Council on Establishing the Security Review System for Mergers and Acquisitions ofDomestic Enterprises by Foreign Investors (《國務院辦公廳關於建立外國投資者併購境內企業安全審查制度的通知》), also known as Circular 6, which was promulgated in 2011. Underthese rules, a security review is required for mergers and acquisitions by foreign investorshaving “national defense and security” concerns and mergers and acquisitions by which foreigninvestors may acquire the “de facto control” of domestic enterprises have “national security”concerns. In addition, when deciding whether a specific merger or acquisition of a domesticenterprise by foreign investors is subject to the security review, the Ministry of Commerce willlook into the substance and actual impact of the transaction. The Security Review Rules furtherprohibits foreign investors from bypassing the security review requirement by structuringtransactions through proxies, trusts, indirect investments, leases, loans, control throughcontractual arrangements or offshore transactions.

There is no requirement for foreign investors in those mergers and acquisitions transactionsalready completed prior to the promulgation of Circular 6 to submit such transactions to theMinistry of Commerce for security review. As we have already obtained the “de facto control”over our affiliated PRC entities prior to the effectiveness of these rules, we do not believe weare required to submit our existing contractual arrangements to the Ministry of Commerce forsecurity review.

However, as there is a lack of clear statutory interpretation on the implementation of the same,there is no assurance that the Ministry of Commerce will not apply these national securityreview-related rules to the acquisition of equity interest in our PRC subsidiaries. If we arefound to be in violation of the Security Review Rules and other PRC laws and regulations withrespect to the merger and acquisition activities in China, or fail to obtain any of the requiredapprovals, the relevant regulatory authorities would have broad discretion in dealing with suchviolation, including levying fines, confiscating our income, revoking our PRC subsidiaries’business or operating licenses, requiring us to restructure or unwind the relevant ownershipstructure or operations. Any of these actions could cause significant disruption to our businessoperations and may materially and adversely affect our business, financial condition andresults of operations. Further, if the business of any target company that we plan to acquire fallsinto the ambit of security review, we may not be able to successfully acquire such companyeither by equity or asset acquisition, capital contribution or through any contractualarrangement. We may grow our business in part by acquiring other companies operating in ourindustry. Complying with the requirements of the relevant regulations to complete suchtransactions could be time consuming, and any required approval processes, including approvalfrom the Ministry of Commerce, may delay or inhibit our ability to complete such transactions,which could affect our ability to expand our business or maintain our market share.

The approval of the CSRC or other PRC government authorities may be required inconnection with this offering under PRC law, and, if required, we cannot predict whetherwe will be able to obtain such approval.

The M&A Rules purport to require offshore special purpose vehicles that are controlled byPRC companies or individuals and that have been formed for the purpose of seeking a publiclisting on an overseas stock exchange through acquisitions of PRC domestic companies orassets to obtain CSRC approval prior to the listing and trading of their securities on an overseasstock exchange. However, the interpretation and application of these regulations remainunclear. If CSRC approval is required, it is uncertain whether it would be possible for us toobtain the approval, how long it would take to obtain such approval, or, even if obtained,whether CSRC would rescind it. Any delay in obtaining, failure to obtain CSRC approval forthis offering, or rescission of CSRC approval if obtained, would subject us to sanctionsimposed by the CSRC and other PRC regulatory authorities.

Our PRC counsel, TransAsia Lawyers, has advised us that, based on its understanding of thecurrent PRC laws and regulations, we will not be required to submit an application to the CSRCfor the approval of the listing and trading of our Class A ordinary shares because (i) the CSRCcurrently has not issued any definitive rules or interpretations concerning whether offeringslike ours under this document are subject to such regulation, (ii) our wholly-owned PRCsubsidiaries were not established through a merger or acquisition of the equity or assets of a“PRC domestic company” as such term is defined under the M&A Rules, and (iii) no provisionin this regulation clearly classifies contractual arrangements as a type of transaction subject toits regulation.

However, we cannot assure you that relevant PRC government authorities, including the CSRC,would reach the same conclusion as our PRC counsel, and in such event we may faceregulatory actions or other sanctions from the CSRC or other PRC regulatory authorities. If itis determined that the approval from the CSRC or other regulatory authorities, or otherprocedures, are required for this offering, it would be uncertain whether we can or how longwill it take to obtain such approval or complete such procedures. Furthermore, we cannotassure you that any obtained approval or clearance will not be rescinded by the governmentalauthorities, and in any of such cases, we may face sanctions from the CSRC or other PRCregulatory authorities for the failure to seek approval or clearance from CSRC or othercompetent regulatory authorities for this offering. These sanctions may include fines andpenalties for our operations in China, restrictions or limitations on our ability to pay dividendsoutside of China, and other forms of sanctions that may materially and adversely affect ourbusiness, results of operations and financial condition, or other actions that could have amaterial and adverse effect on our business, financial condition, results of operations,reputation and prospects, as well as the trading price of our listed securities. The CSRC or otherPRC regulatory agencies may also take actions requiring us, or making it advisable for us, tohalt this offering before the settlement and delivery of the securities that we are offering.Consequently, if you engage in market trading or other activities in anticipation of and priorto the settlement and delivery of the securities we are offering, you would be doing so at therisk that the settlement and delivery may not occur. In addition, if the CSRC or other regulatoryagencies later promulgate new rules or explanations requiring that we obtain their approvals forthis offering, we may be unable to obtain a waiver of such approval requirements, if and whenprocedures are established to obtain such a waiver. Any uncertainties or negative publicityregarding such approval requirement could materially and adversely affect our business,prospects, financial condition, reputation, and the trading price of our listed shares.

Several PRC authorities recently issued the Opinions on Strictly Combating Illegal SecuritiesActivities (《關於依法從嚴打擊證券違法活動的意見》) which emphasize on the prevention ofillegal securities activities and tightened supervision over overseas listings by China-basedcompanies. The opinions aim to achieve this by establishing a regulatory system and revisingthe existing rules for overseas listings of Chinese entities and affiliates including potentialextraterritorial application of China’s securities laws. As the opinions are new, officialguidance and implementation rules have not been issued and the final interpretation of andpotential impact from these opinions remain unclear at this stage. As of the date of thisdocument, we have not received any inquiry, notice, warning, or sanction regarding thisoffering from the CSRC or any other PRC regulatory agencies. However, we cannot assure youthat any new rules or regulations promulgated in the future will not impose additionalrequirements on us. As of the date of this document, we have not received any inquiry, notice,warning, or sanction regarding this offering from the CSRC or any other PRC regulatoryagencies.

The heightened scrutiny over acquisition transactions by the PRC tax authorities mayhave a negative impact on our business operations, our acquisition or restructuringstrategy or the value of your investment in us.

The State Administration of Taxation has issued several rules and notices to tighten the scrutinyover acquisition transactions in recent years, including the Notice on Certain Corporate IncomeTax Matters Related to Indirect Transfer of Properties by Non-PRC Resident Enterprises (《國家稅務總局關於非居民企業間接轉讓財產企業所得稅若干問題的公告》) issued in February2015, or SAT Circular 7. Pursuant to these rules and notices, except for a few circumstancesfalling into the scope of the safe harbor provided by SAT Circular 7, such as open markettrading of stocks in public companies listed overseas, if a non-PRC resident enterpriseindirectly transfers PRC taxable properties (i.e. properties of an establishment or a place in thePRC, real estate properties in the PRC or equity investments in a PRC tax resident enterprise)by disposing of equity interest or other similar rights in an overseas holding company, withouta reasonable commercial purpose and resulting in the avoidance of PRC enterprise income tax,such indirect transfer should be deemed as a direct transfer of PRC taxable properties and gainsderived from such indirect transfer may be subject to the PRC withholding tax at a rate of upto 10%. SAT Circular 7 sets out several factors to be taken into consideration by tax authoritiesin determining whether an indirect transfer has a reasonable commercial purpose, such aswhether the main value of equity interest in an overseas holding company is derived directlyor indirectly from PRC taxable properties. An indirect transfer satisfying all the followingcriteria will be deemed to lack reasonable commercial purpose and be taxable under PRC lawwithout considering other factors set out by SAT Circular 7: (i) 75% or more of the equity valueof the intermediary enterprise being transferred is derived directly or indirectly from the PRCtaxable properties; (ii) at any time during the one-year period before the indirect transfer, 90%or more of the asset value of the intermediary enterprise (excluding cash) is comprised directlyor indirectly of investments in the PRC, or 90% or more of its income is derived directly orindirectly from the PRC; (iii) the functions performed and risks assumed by the intermediaryenterprise and any of its subsidiaries that directly or indirectly hold the PRC taxable propertiesare limited and are insufficient to prove their economic substance; and (iv) the foreign taxpayable on the gain derived from the indirect transfer of the PRC taxable properties is lowerthan the potential PRC income tax on the direct transfer of such assets. SAT Circular 7 alsointroduces an interest regime by providing that where a transferor fails to file and pay tax ontime, and where a withholding agent fails to withhold the tax, interest will be charged on adaily basis. Both the foreign transferor and the transferee, and the PRC tax resident enterprisewhose equity interests are being transferred may voluntarily report the transfer by submittingthe documents required in SAT Circular 7.

Although SAT Circular 7 provides clarity in many important areas, such as reasonablecommercial purpose, there are still uncertainties on the tax reporting and payment obligationswith respect to future private equity financing transactions, share exchange or othertransactions involving the transfer of shares in non-PRC resident companies. Our company andother non-resident enterprises in our group may be subject to filing obligations or being taxedif our company and other non-resident enterprises in our group are transferors in suchtransactions, and may be subject to withholding obligations if our company and othernon-resident enterprises in our group are transferees in such transactions. For the transfer ofshares in our company by investors who are non-PRC resident enterprises, our PRCsubsidiaries may be requested to assist in the filing under the rules and notices. As a result, wemay be required to expend valuable resources to comply with these rules and notices or torequest the relevant transferors from whom we purchase taxable assets to comply, or toestablish that our company and other non-resident enterprises in our group should not be taxedunder these rules and notices, which may have a material adverse effect on our financialcondition and results of operations.

RISK FACTORS

– 107 –

We cannot assure you that the PRC tax authorities will not, at their discretion, adjust anycapital gains and impose tax return filing obligations on us or require us to provide assistancefor the investigation of PRC tax authorities with respect thereto. In the future, we may conductacquisitions or disposals of properties that may involve complex corporate structures. If thePRC tax authorities make adjustments to the taxable income of these transactions under SATCircular 7, our income tax expenses associated with such potential transactions may beincreased, which may have a material adverse effect on our financial condition and results ofoperations.

We face certain risks relating to the real properties that we lease.

We lease office space for our operations in China. Any defects in lessors’ title to the leasedproperties may disrupt our use of our offices, which may in turn adversely affect our businessoperations. For example, certain buildings and the underlying land are not allowed to be usedfor industrial or commercial purposes without relevant authorities’ approval, and the lease ofsuch buildings to companies like us may subject the lessor to pay premium fees to the PRCgovernment. We cannot assure you that the lessor has obtained all or any of approvals from therelevant governmental authorities. In addition, some of our lessors have not provided us withdocumentation evidencing their title to the relevant leased properties. We cannot assure youthat title to these properties we currently lease will not be challenged. In addition, we have notregistered most of our lease agreements with relevant PRC governmental authorities asrequired by PRC law, and although failure to do so does not in itself invalidate the leases, wemay not be able to defend these leases against bona fide third parties.

As of the Latest Practicable Date, we are not aware of any actions, claims or investigationsbeing contemplated by government authorities with respect to the defects in our leased realproperties or any challenges by third parties to our use of these properties. However, if thirdparties who purport to be property owners or beneficiaries of the mortgaged propertieschallenge our right to use the leased properties, we may not be able to protect our leaseholdinterest and may be ordered to vacate the affected premises, which could in turn materially andadversely affect our business and operating results.

Failure to comply with PRC labor laws and make adequate contributions to variousemployee benefit plans as required by PRC regulations may subject us to penalties.

Companies operating in China are required to register with governmental authorities andparticipate in various government sponsored employee benefit plans, including certain socialinsurance and housing funds, and contribute to these plans in amounts equal to certainpercentages of salaries, including bonuses and allowances, of employees up to a maximumamount specified by the local government authorities from time to time at the locations wherethose employees are based. However, requirements relating to employee benefit plans have notbeen implemented consistently by local governments in China, given the different levels ofeconomic development in different regions. We believe that we have made adequate socialinsurance and housing fund contributions for the majority of our employees, however, wecannot assure you that local governments will not have different views as to what constitutesstrict compliance with the requirements for contributions to employee benefit plans. Our socialinsurance and housing fund contributions for a small number of our employees withperformance-based salaries may not be adequate, as we could not foresee these employees’performance and therefore their salaries accurately. We may be required to make up thecontributions for these employee benefit plans as well as to pay late fees and fines.

Our significant deposits in certain banks in China may be at risk if these banks gobankrupt or otherwise do not have the liquidity to pay us during our deposit period.

As of June 30, 2021, we had US$2.4 billion in cash and cash equivalent, bank deposits andshort term investments, such as time deposits, with large domestic banks in China. Ourremaining cash, cash equivalents and short-term investments were held by financial institutionsin the United States and Hong Kong. The terms of these deposits are, in general, up to twelvemonths. Historically, deposits in Chinese banks were viewed as secure due to the state policyon protecting depositors’ interests. However, the new Bankruptcy Law that came into effect in2007 contains an article expressly stating that the State Council may promulgateimplementation measures for the bankruptcy of Chinese banks based on the Bankruptcy Law,so the law contemplates the possibility that a Chinese bank may go bankrupt. In addition,foreign banks have been gradually permitted to operate in China since China’s accession to theWorld Trade Organization and have become strong competitors of Chinese banks in manyrespects, which may have increased the risk of bankruptcy or illiquidity for Chinese banks,including those in which we have deposits. In the event of bankruptcy or illiquidity of any oneof the banks which holds our deposits, we are unlikely to claim our deposits back in full sincewe are unlikely to be classified as a secured creditor based on PRC laws.

On May 1, 2015, China’s new Deposit Insurance Regulation (《中華人民共和國存款保險條例》) came into effect, pursuant to which banking financial institutions, such as commercialbanks, established in China will be required to purchase deposit insurance for deposits in RMBand in foreign currency. Under this regulation, depositors will be fully indemnified for theirdeposits and interests in an aggregate amount up to a limit of RMB500,000. Deposits orinterests over such limit will only be covered by the bank’s liquidation assets. Therefore,although this requirement to purchase deposit insurance may help, to a certain extent, preventChinese banks from going bankrupt, it would not be effective in providing effective protectionfor our accounts, as our aggregate deposits are much higher than the compensation limit.

Our ADSs may be delisted under the Holding Foreign Companies Accountable Act if thePCAOB is unable to inspect auditors who are located in China. The delisting of our ADSs,or the threat of their being delisted, may materially and adversely affect the value of yourinvestment. Additionally, the inability of the PCAOB to conduct inspections deprives ourinvestors with the benefits of such inspections.

The Holding Foreign Companies Accountable Act, or the HFCA Act, was enacted on December18, 2020. The HFCA Act states if the SEC determines that we have filed audit reports issuedby a registered public accounting firm that has not been subject to inspection by the PCAOBfor three consecutive years beginning in 2021, the SEC shall prohibit our shares or ADSs frombeing traded on a national securities exchange or in the over the counter trading market in theU.S. On November 5, 2021, the SEC approved the PCAOB rule that provides a framework forthe PCAOB to determine whether it is unable to inspect or investigate completely registeredpublic accounting firms located in a foreign jurisdiction because of a position taken by one ormore authorities in that jurisdiction. The rule states that the PCAOB will make thesedeterminations promptly.

Our auditor, the independent registered public accounting firm that issues the audit reportincluded elsewhere in this document, as an auditor of companies that are traded publicly in theUnited States and a firm registered with the PCAOB, is subject to laws in the United Statespursuant to which the PCAOB conducts regular inspections to assess its compliance with theapplicable professional standards. Since our auditor is located in China, a jurisdiction wherethe PCAOB has been unable to conduct inspections without the approval of the Chineseauthorities, our auditor is currently not inspected by the PCAOB.

RISK FACTORS

On March 24, 2021, the SEC has adopted interim final rules relating to the implementation ofcertain disclosure and documentation requirements of the HFCA Act. We will be required tocomply with these rules if the SEC identifies us as having a “non-inspection” year under aprocess to be subsequently established by the SEC. The SEC is assessing how to implementother requirements of the HFCA Act, including the listing and trading prohibition requirementsdescribed above.

On June 22, 2021, the U.S. Senate passed a bill which, if passed by the U.S. House ofRepresentatives and signed into law, would reduce the number of consecutive non-inspectionyears required for triggering the prohibitions under the HFCA Act from three years to two.

The SEC may propose additional rules or guidance that could impact us if our auditor thatissued the audit report included in our annual report on Form 20-F is not subject to PCAOBinspection. For example, on August 6, 2020, the President’s Working Group on FinancialMarkets, or the PWG, issued the Report on Protecting United States Investors from SignificantRisks from Chinese Companies to the then President of the United States. This reportrecommended the SEC implement five recommendations to address companies fromjurisdictions that do not provide the PCAOB with sufficient access to fulfil its statutorymandate. Some of the concepts of these recommendations were implemented with theenactment of the HFCA Act. However, some of the recommendations were more stringent thanthe HFCA Act. For example, if a company was not subject to PCAOB inspection, the reportrecommended that the transition period before a company would be delisted would end onJanuary 1, 2022.

The SEC has announced that the SEC staff is preparing a consolidated proposal for the rulesregarding the implementation of the HFCA Act and to address the recommendations in thePWG report. It is unclear when the SEC will complete its rulemaking and when such rules willbecome effective and what, if any, of the PWG recommendations will be adopted. Theimplications of this possible regulation in addition the requirements of the HFCA Act areuncertain. Such uncertainty could cause the market price of our ADSs to be materially andadversely affected, and our securities could be delisted or prohibited from being traded“over-the-counter” earlier than would be required by the HFCA Act. If our securities are unableto be listed on another securities exchange by then, such a delisting would substantially impairyour ability to sell or purchase our ADSs when you wish to do so, and the risk and uncertaintyassociated with a potential delisting would have a negative impact on the price of our ADSs.

The PCAOB’s inability to conduct inspections in China prevents it from fully evaluating theaudits and quality control procedures of our independent registered public accounting firm. Asa result, we and investors in our ordinary shares are deprived of the benefits of such PCAOBinspections. The inability of the PCAOB to conduct inspections of auditors in China makes itmore difficult to evaluate the effectiveness of our independent registered public accountingfirm’s audit procedures or quality control procedures as compared to auditors outside of Chinathat are subject to the PCAOB inspections, which could cause investors and potential investorsin our stock to lose confidence in our audit procedures and reported financial information andthe quality of our financial statements.

In May 2013, the PCAOB announced that it had entered into a Memorandum of Understandingon Enforcement Cooperation with the CSRC and the PRC Ministry of Finance, whichestablishes a cooperative framework between the parties for the production and exchange ofaudit documents relevant to investigations undertaken by the PCAOB in the PRC or by theCSRC or the PRC Ministry of Finance in the United States. The PCAOB continues to be indiscussions with the CSRC and the PRC Ministry of Finance to permit joint inspections in thePRC of audit firms that are registered with the PCAOB and audit Chinese companies that tradeon U.S. exchanges.

Proceedings instituted by the SEC against certain PRC-based accounting firms, includingthe auditor of our consolidated financial statements in our annual reports on Form 20-Ffiled with the SEC, could result in our financial statements being determined to not be incompliance with the requirements of the Securities Exchange Act of 1934, as amended, orthe Exchange Act.

In December 2012, the SEC instituted administrative proceedings against the Big FourPRC-based accounting firms, including the auditor of our consolidated financial statements inour annual reports on Form 20-F filed with the SEC, alleging that these firms had violated U.S.securities laws and the SEC’s rules and regulations thereunder by failing to provide to the SECthe firms’ audit work papers with respect to certain PRC-based companies that are publiclytraded in the United States.

On January 22, 2014, the administrative law judge presiding over the matter rendered an initialdecision that each of the firms had violated the SEC’s rules of practice by failing to produceaudit papers and other documents to the SEC. The initial decision censured each of the firmsand barred them from practicing before the SEC for a period of six months.

On February 6, 2015, the four China-based accounting firms each agreed to a censure and topay a fine to the SEC to settle the dispute and avoid suspension of their ability to practicebefore the SEC and audit U.S.-listed companies. The settlement required the firms to followdetailed procedures and to seek to provide the SEC with access to Chinese firms’ auditdocuments via the CSRC. Under the terms of the settlement, the underlying proceeding againstthe four China-based accounting firms was deemed dismissed with prejudice four years afterentry of the settlement. The four-year mark occurred on February 6, 2019. While we cannotpredict if the SEC will further challenge the four China-based accounting firms’ compliancewith U.S. law in connection with U.S. regulatory requests for audit work papers or if the resultsof such a challenge would result in the SEC imposing penalties such as suspensions, if theaccounting firms are subject to additional remedial measures, our ability to file our financialstatements in compliance with SEC requirements could be impacted. A determination that wehave not timely filed financial statements in compliance with SEC requirements couldultimately lead to the delisting of our ADSs from Nasdaq or the termination of the registrationof our ADSs under the Exchange Act, or both, which would substantially reduce or effectivelyterminate the trading of our ADSs in the United States.

It may be difficult for overseas regulators to conduct investigation or collect evidencewithin China.

Shareholder claims or regulatory investigation that are common in the United States generallyare difficult to pursue as a matter of law or practicality in China. For example, in China, thereare significant legal and other obstacles to providing information needed for regulatoryinvestigations or litigation initiated outside China. Although the authorities in China mayestablish a regulatory cooperation mechanism with the securities regulatory authorities ofanother country or region to implement cross-border supervision and administration, suchcooperation with the securities regulatory authorities in the Unities States may not be efficientin the absence of mutual and practical cooperation mechanism. Furthermore, according toArticle 177 of the PRC Securities Law (《中華人民共和國證券法》), or Article 177, whichbecame effective in March 2020, no overseas securities regulator is allowed to directly conductinvestigation or evidence collection activities within the territory of the PRC. While detailedinterpretation of or implementation rules under Article 177 have yet to be promulgated, theinability for an overseas securities regulator to directly conduct investigation or evidencecollection activities within China may further increase difficulties faced by you in protectingyour interests.

RISKS RELATING TO OUR SHARES, OUR ADSs AND THE LISTING

As a company applying for listing under Chapter 19C, we adopt different practices as tocertain matters as compared with many other companies listed on the Hong Kong StockExchange.

As we are applying for a listing under Chapter 19C of the Hong Kong Listing Rules, we willnot be subject to certain provisions of the Hong Kong Listing Rules pursuant to Rule 19C.11,including, among others, rules on notifiable transactions, connected transactions, share optionschemes, content of financial statements as well as certain other continuing obligations. Inaddition, in connection with the Listing, we have applied for a number of waivers and/orexemptions from strict compliance with the Hong Kong Listing Rules, the Companies(Winding Up and Miscellaneous Provisions) Ordinance, the Takeovers Codes and the SFO. Asa result, we will adopt different practices as to those matters as compared with other companieslisted on the Hong Kong Stock Exchange that do not enjoy those exemptions or waivers. Foradditional information, see “Waivers and Exemptions.”

Furthermore, if 55% or more of the total worldwide trading volume, by dollar value, of ourClass A ordinary shares and ADSs over our most recent fiscal year takes place on the HongKong Stock Exchange, the Hong Kong Stock Exchange will regard us as having a dual primarylisting in Hong Kong and we will no longer enjoy certain exemptions or waivers from strictcompliance with the requirements under the Hong Kong Listing Rules, the Companies(Winding Up and Miscellaneous Provisions) Ordinance, the Takeovers Codes and the SFO,which could result in us having to amend our corporate structure and Articles of Associationand we may incur of incremental compliance costs.

The trading price for our ADSs has been and is likely to continue be, and the trading priceof our Class A ordinary shares can be, volatile, regardless of our operating performance,which could result in substantial losses to holders of our Class A ordinary shares and/orthe ADSs.

The trading prices of our ADSs has been and is likely to continue to be volatile and couldfluctuate widely in response to in response to a variety of factors, many of which are beyondour control. The trading price of our Class A ordinary shares, likewise, can be volatile forsimilar or different reasons. For example, the trading price of our ADSs ranged from US$28.93to US$52.33 per ADS in 2020. The trading price of our listed securities is likely to remainvolatile and could fluctuate widely due to factors beyond our control. This may happen becauseof broad market and industry factors, like the performance and fluctuation of the market pricesof other companies with business operations located mainly in China that have listed theirsecurities in Hong Kong and/or the United States. A number of Chinese companies have listedor are in the process of listing their securities on stock markets in Hong Kong and/or the UnitedStates. The securities of some of these companies have experienced significant volatility,including price declines in connection with their initial public offerings. The tradingperformances of these Chinese companies’ securities after their offerings may affect theattitudes of investors toward Chinese companies listed in Hong Kong and/or the United Statesin general and consequently may impact the trading performance of our Class A ordinary sharesand/or ADSs, regardless of our actual operating performance.

RISK FACTORS

In addition to market and industry factors, the price and trading volume for our Class Aordinary shares and/or ADSs may be highly volatile for factors specific to our own operations,including (but not limited to) the following:

• variations in our revenues, earnings, cash flow and data related to our active user base oruser engagement;

• announcements of new investments, acquisitions, strategic partnerships or joint ventures;

• announcements of new services and expansions by us or our competitors;

• potential litigation or regulatory investigations.

Substantial future sales or perceived potential sales of our Class A ordinary shares, ADSs,or other equity or equity-linked securities in the public market could cause the price ofour Class A ordinary shares and/or ADSs to decline

Sales of our Class A ordinary shares, ADSs, or other equity or equity-linked securities in thepublic market, or the perception that these sales could occur, could cause the market price ofour Class A ordinary shares and/or ADSs to decline significantly. All of our Class A ordinaryshares represented by ADSs were freely transferable by persons other than our affiliateswithout restriction or additional registration under the U.S. Securities Act. The Class Aordinary shares held by our affiliates are also available for sale, subject to volume and otherrestrictions as applicable under Rule 144 of the U.S. Securities Act any applicable lock-upagreement, under trading plans adopted pursuant to Rule 10b5-1 or otherwise. Our controllingshareholders are not subject to the lock up requirements under the Hong Kong Listing Rulesin this Global Offering and the Selling Shareholder will enter into a lock-up undertakingpursuant to the Hong Kong Underwriting Agreement for 90 days which is shorter than thelock-up period under Rule 10.07 of the Hong Kong Listing Rules. Furthermore our controllingshareholders may sell additional shares of us after the expiry of lock-up undertaking. Wecannot predict what effect, if any, market sales of securities held by our controllingshareholders or any other shareholder or the availability of these securities for future sale willhave on the market price of our Shares and ADSs. See “Underwriting” for more detaileddescriptions of the lock-up undertaking by our directors, executive officers and principalshareholders and the restrictions on selling our securities after this Global Offering.

Divesture in the future of our Class A ordinary shares and/or ADSs by shareholders, theannouncement of any plan to divest our Class A ordinary shares and/or ADS, or hedgingactivity by third-party financial institutions in connection with similar derivative or otherfinancing arrangements entered into by shareholders, could cause the price of our Class Aordinary shares and/or ADSs to decline.

RISK FACTORS

If securities or industry analysts do not publish research or reports about our business,or if they adversely change their recommendations regarding our Class A ordinary sharesand/or ADSs, the trading price for our Class A ordinary shares and/or ADSs and tradingvolume could decline.

The trading market for our Class A ordinary shares and/or ADSs will be influenced by researchor reports that industry or securities analysts publish about our business. If one or moreanalysts who cover us downgrade our Class A ordinary shares and/or ADSs, the trading pricefor our Class A ordinary shares and/or ADSs would likely decline. If one or more of theseanalysts cease to cover us or fail to regularly publish reports on us, we could lose visibility inthe financial markets, which in turn could cause the trading price or trading volume for ourClass A ordinary shares and/or ADSs to decline.

The sale or availability for sale, or perceived sale or availability for sale, of substantialamounts of our listed securities could adversely affect their trading price.

Sales of substantial amounts of our Class A ordinary shares and/or ADSs in the public market,or the perception that these sales could occur, could adversely affect the trading price of ourClass A ordinary shares and/or ADSs and could materially impair our ability to raise capitalthrough equity offerings in the future. We cannot predict what effect, if any, market sales ofsecurities held by our significant shareholders or any other shareholder or the availability ofthese securities for future sale will have on the trading price of our Class A ordinary sharesand/or ADSs.

Our dual-class voting structure will limit your ability to influence corporate matters andcould discourage others from pursuing any change of control transactions that holders ofour Class A ordinary shares and ADSs may view as beneficial.

Our ordinary shares are divided into Class A ordinary shares and Class B ordinary shares.Holders of Class A ordinary shares are entitled to one vote per share, while holders of ClassB ordinary shares are entitled to three votes per share. All of the outstanding ordinary sharesheld by SINA as of the Latest Practicable Date are Class B ordinary shares. All other ordinaryshares that are outstanding as of the Latest Practicable Date are Class A ordinary shares. Weintend to maintain the dual-class voting structure in the future. Each Class B ordinary share isconvertible into one Class A ordinary share at any time by the holder thereof. Class A ordinaryshares are not convertible into Class B ordinary shares under any circumstances. Upon anytransfer of Class B ordinary shares by a holder thereof to any person or entity which is not anaffiliate (as defined in our Articles of Association) of such holder, such Class B ordinary sharesshall be automatically and immediately converted into the equal number of Class A ordinaryshares. In addition, each Class B ordinary share shall automatically and immediately beconverted into one Class A ordinary share if at any time SINA and its affiliates (as defined inour Articles of Association) in the aggregate hold less than five percent (5%) of the issuedClass B ordinary shares in our company, and no Class B ordinary shares shall be issued by ourcompany thereafter.

Due to the disparate voting powers attached to these two classes of ordinary shares, SINAowned approximately 44.6% of our total issued and outstanding ordinary shares and 70.7% ofthe voting power of our outstanding shares as of June 30, 2021. Therefore, SINA will havedecisive influence over matters requiring shareholders’ approval, including election ofdirectors and significant corporate transactions, such as a merger or sale of our company. Thisconcentrated control will limit your ability to influence corporate matters and could discourageothers from pursuing any potential merger, takeover or other change of control transactions thatholders of Class A ordinary shares and ADSs may view as beneficial.

Techniques employed by short sellers may drive down the trading price of our Class Aordinary shares and/or ADSs.

Short selling is the practice of selling securities that the seller does not own but rather hasborrowed from a third-party with the intention of buying identical securities back at a later dateto return to the lender. The short seller hopes to profit from a decline in the value of thesecurities between the sale of the borrowed securities and the purchase of the replacementshares, as the short seller expects to pay less in that purchase than it received in the sale. Asit is in the short seller’s interest for the price of the security to decline, many short sellerspublish, or arrange for the publication of, negative opinions regarding the relevant issuer andits business prospects in order to create negative market momentum and generate profits forthemselves after selling a security short. These short attacks have, in the past, led to selling ofshares in the market.

Public companies listed in the United States that have substantially all of their operations inChina have been the subject of short selling. Much of the scrutiny and negative publicity hascentered on allegations of a lack of effective internal control over financial reporting resultingin financial and accounting irregularities and mistakes, inadequate corporate governancepolicies or a lack of adherence thereto and, in many cases, allegations of fraud. As a result,many of these companies are now conducting internal and external investigations into theallegations and, in the interim, are subject to shareholder lawsuits and/or SEC enforcementactions.

It is not clear what effect such negative publicity could have on us. If we were to become thesubject of any unfavorable allegations, whether such allegations are proven to be true or untrue,we could have to expend a significant amount of resources to investigate such allegationsand/or defend ourselves. While we would strongly defend against any such short seller attacks,we may be constrained in the manner in which we can proceed against the relevant short sellerby principles of freedom of speech, applicable state law or issues of commercialconfidentiality. Such a situation could be costly and time-consuming and could distract ourmanagement from growing our business. Even if such allegations are ultimately proven to begroundless, allegations against us could severely impact our business operations andstockholder’s equity, and any investment in our Class A ordinary shares and/or ADSs could begreatly reduced or rendered worthless.

Because we do not expect to pay dividends in the foreseeable future, investors must relyon price appreciation of our Class A ordinary shares and/or ADSs for return on theirinvestments.

We currently intend to retain most, if not all, of our available funds and any future earnings tofund the development and growth of our business. As a result, we do not expect to pay any cashdividends in the foreseeable future. Therefore, investors should not rely on an investment inour Class A ordinary shares and/or ADSs as a source for any future dividend income.

Our board of directors has complete discretion as to whether to distribute dividends, subject toCayman Islands law. In addition, our shareholders may by ordinary resolution declaredividends, but no dividend may exceed the amount recommended by our directors. UnderCayman Islands law, our company may pay dividends only out of either profit or sharepremium account, provided that in no circumstances may a dividend be paid if this would resultin our company being unable to pay its debts as they fall due in the ordinary course of business.Even if our board of directors decides to declare and pay dividends, the timing, amount andform of future dividends, if any, will depend on, among other things, our future results ofoperations and cash flow, our capital requirements and surplus, the amount of distributions, if

any, received by us from our subsidiary, our financial condition, contractual restrictions andother factors deemed relevant by our board of directors. Accordingly, the return to the holdersof our Class A ordinary shares and/or ADSs will likely depend entirely upon any future priceappreciation of our ADSs. There is no guarantee that our listed securities will appreciate invalue in the future or even maintain the price at which the investors purchased these securities.Investors may not realize a return on their investment in our Class A ordinary shares and/orADSs and may even lose their entire investment.

Our shareholders may be subject to PRC income tax on dividends from us or on any gainrealized on the transfer of our Class A ordinary shares and/or ADSs.

Under the Enterprise Income Tax Law and its implementation rules, subject to any applicabletax treaty or similar arrangement between the PRC and the jurisdiction of residence of theholders of our Class A ordinary share and/or ADSs that provides for a different income taxarrangement, PRC withholding tax at the rate of 10% is normally applicable to dividends fromPRC sources payable to investors that are non-PRC resident enterprises, which do not have anestablishment or place of business in the PRC, or which have such establishment or place ofbusiness if the relevant income is not effectively connected with the establishment or place ofbusiness. Any gain realized on the transfer of ADSs or shares by such non-PRC residententerprise investors is also subject to 10% PRC income tax if such gain is regarded as incomederived from sources within the PRC, unless a tax treaty or similar arrangement otherwiseprovides. Under the PRC Individual Income Tax Law and its implementation rules, dividendsfrom sources within the PRC paid to foreign individual investors who are not PRC residentsare generally subject to a PRC withholding tax at a rate of 20% and gains from PRC sourcesrealized by such investors on the transfer of American depositary shares or shares are generallysubject to 20% PRC income tax, in each case, subject to any reduction or exemption set forthin applicable tax treaties and similar arrangements and PRC laws. Although substantially all ofour business operations are in China, it is unclear whether dividends we pay with respect to ourClass A ordinary shares and/or ADSs, or the gain realized from the transfer of our Class Aordinary shares and/or ADSs, would be treated as income derived from sources within the PRCand as a result be subject to PRC income tax if we were considered a PRC resident enterprise,as described above. If PRC income tax were imposed on gains realized through the transfer ofour ADSs or on dividends paid to our non-PRC resident investors, the value of the investmentin our Class A ordinary shares and/or ADSs may be materially and adversely affected.Furthermore, the holders of our Class A ordinary shares and/or ADSs whose jurisdictions ofresidence have tax treaties or similar arrangements with China may not qualify for benefitsunder such tax treaties or arrangements.

We may be classified as a passive foreign investment company under U.S. federal incometax law, which could result in adverse consequences to U.S. investors in our Class Aordinary shares or ADSs.

Depending upon the value of our assets, which is determined based, in part, on the market valueof our Class A ordinary shares and ADSs, and the nature of our assets and income over time,we could be classified as a passive foreign investment company (a “PFIC”) for U.S. federalincome tax purposes. We will be classified as a PFIC for any taxable year if either (i) 75% ormore of our gross income for the taxable year is passive income or (ii) 50% or more of thevalue of our assets (determined on the basis of a quarterly average) is attributable to assets thatproduce or are held for the production of passive income (the “asset test”).

RISK FACTORS

– 116 –

Although the law in this regard is not entirely clear, we treat our VIEs as being owned by usfor U.S. federal income tax purposes because we control their management decisions and weare entitled to substantially all of their economic benefits, and, as a result, we consolidate theirresults of operations in our consolidated U.S. GAAP financial statements. If it weredetermined, however, that we are not the owner of our VIEs for U.S. federal income taxpurposes, we would likely be treated as a PFIC for our current taxable year and any subsequenttaxable year. Assuming that we are the owner of our VIEs for U.S. federal income tax purposesand based on our income and assets and the value of our Class A ordinary shares and ADSs,we do not expect to be a PFIC for our current taxable year or for the foreseeable future.

Because PFIC status is a factual determination made annually after the close of each taxableyear on the basis of the composition of our income and assets, there can be no assurance thatwe will not be a PFIC for the current taxable year or any future taxable year. Fluctuations inthe market price of our Class A ordinary shares or ADSs may cause us to become a PFIC forthe current or subsequent taxable years because the value of our assets for purposes of the assettest, including the value of our goodwill and unbooked intangibles, may be determined byreference to the market price of our Class A ordinary shares or ADSs from time to time (whichmay be volatile). In estimating the value of our goodwill and other unbooked intangibles, wehave taken into account our current market capitalization. If our market capitalization declines,we may be classified as a PFIC for the current taxable year or future taxable years. In addition,the overall level of our passive assets will be affected by how, and how quickly, we spend ourliquid assets, including the proceeds from this offering. Under circumstances where ourrevenue from activities that produce passive income significantly increase relative to ourrevenue from activities that produce non-passive income, or where we determine not to deploysignificant amounts of cash for active purposes, our risk of becoming classified as a PFIC maysubstantially increase. Furthermore, because there are uncertainties in the application of therelevant rules, it is possible that the Internal Revenue Service may challenge our classificationof certain income or assets as non-passive, or our valuation of our goodwill and other unbookedintangibles, each of which may result in our company becoming classified as a PFIC for thecurrent or subsequent taxable years.

Our Articles of Association contain anti-takeover provisions that could have a materialadverse effect on the rights of holders of our ordinary shares and ADSs.

Our Articles of Association contain provisions to limit the ability of others to acquire controlof our company or cause us to engage in change-of-control transactions. These provisionscould have the effect of depriving our shareholders of an opportunity to sell their shares at apremium over prevailing market prices by discouraging third parties from seeking to obtaincontrol of our company in a tender offer or similar transaction. For example, our board ofdirectors has the authority, without further action by our shareholders, to issue preferred sharesin one or more series and to fix their designations, powers, preferences, privileges, and relativeparticipating, optional or special rights and the qualifications, limitations or restrictions,including dividend rights, conversion rights, voting rights, terms of redemption and liquidationpreferences, any or all of which may be greater than the rights associated with our ordinaryshares, in the form of ADS or otherwise. Preferred shares could be issued quickly with termscalculated to delay or prevent a change in control of our company or make removal ofmanagement more difficult. If our board of directors decides to issue preferred shares, the priceof our Class A ordinary shares and/or ADSs may fall and the voting and other rights of theholders of our ordinary shares and ADSs may be materially and adversely affected.

RISK FACTORS

Our shareholders may face difficulties in protecting their interests, and the ability toprotect their rights through Hong Kong or U.S. courts may be limited, because we areincorporated under Cayman Islands law.

We are an exempted company incorporated under the laws of the Cayman Islands. Ourcorporate affairs are governed by our Articles of Association, the Cayman Companies Act andthe common law of the Cayman Islands. The rights of our shareholders to take action againstour directors, actions by our minority shareholders and the fiduciary duties of our directors toour company under Cayman Islands law are to a large extent governed by the common law ofthe Cayman Islands. The common law of the Cayman Islands is derived in part fromcomparatively limited judicial precedent in the Cayman Islands as well as from the commonlaw of England, the decisions of whose courts are of persuasive authority, but are not binding,on a court in the Cayman Islands. The rights of our shareholders and the fiduciary duties of ourdirectors under Cayman Islands law are not as clearly established as they would be understatutes or judicial precedent in some jurisdictions in the United States or Hong Kong. Inparticular, the Cayman Islands has a less developed body of securities laws than the UnitedStates. Some U.S. states, such as Delaware, have more fully developed and judiciallyinterpreted bodies of corporate law than the Cayman Islands. In addition, Cayman Islandscompanies may not have standing to initiate a shareholder derivative action in a federal courtof the United States or a court in Hong Kong.

The Cayman Islands courts are also unlikely:

• to recognize or enforce against us judgments of courts of the United States based oncertain civil liability provisions of U.S. securities laws; and

• to impose liabilities against us, in original actions brought in the Cayman Islands, basedon certain civil liability provisions of U.S. securities laws that are penal in nature.

In those circumstances, although there is no statutory enforcement in the Cayman Islands ofjudgments obtained in the U.S., the courts of the Cayman Islands will recognize and enforcea foreign money judgment of a foreign court of competent jurisdiction without retrial on themerits based on the principle that a judgment of a competent foreign court imposes upon thejudgment debtor an obligation to pay the sum for which judgment has been given providedcertain conditions are met. For such a foreign judgment to be enforced in the Cayman Islands,such judgment must be final and conclusive and for a liquidated sum, and must not be inrespect of taxes or a fine or penalty, inconsistent with a Cayman Islands judgment in respectof the same matter, impeachable on the grounds of fraud or obtained in a manner, and or be ofa kind the enforcement of which is, contrary to natural justice or the public policy of theCayman Islands (awards of punitive or multiple damages may well be held to be contrary topublic policy). A Cayman Islands court may stay enforcement proceedings if concurrentproceedings are being brought elsewhere.

Certain corporate governance practices in the Cayman Islands, which is our home country,differ significantly from requirements for companies incorporated in other jurisdictions such asthe United States and Hong Kong. To the extent we choose to follow home country practicewith respect to corporate governance matters, our shareholders may be afforded less protectionthan they otherwise would under rules and regulations applicable to U.S. domestic issuers orcompanies incorporated in Hong Kong.

As a result of all of the above, our public shareholders may have more difficulty in protectingtheir interests in the face of actions taken by our management, members of our board ofdirectors or our controlling shareholders than they would as public shareholders of a companyincorporated in the United States.

RISK FACTORS

– 118 –

Certain judgments obtained against us by our shareholders may not be enforceable.

We are a Cayman Islands exempted company and all of our assets are located outside of theUnited States. Substantially all of our current operations are conducted in China. In addition,a majority of our directors and senior management named in this document reside outside theUnited States or Hong Kong. Substantially all of the assets of these persons are located outsidethe United States. As a result, it may be difficult or impossible for our shareholders to bringan action against us or against these individuals in the United States or Hong Kong in the eventthat such shareholders believe that their rights have been infringed under the U.S. federalsecurities laws, Hong Kong laws, or otherwise. Even if such shareholders are successful inbringing an action of this kind, the laws of the Cayman Islands and of China may render suchshareholders unable to enforce a judgment against our assets or the assets of our directors andofficers.

We are a foreign private issuer within the meaning of the rules under the Exchange Act,and as such we are exempt from certain provisions applicable to United States domesticpublic companies.

Because we are a foreign private issuer under the Exchange Act, we are exempt from certainprovisions of the securities rules and regulations in the United States that are applicable to U.S.domestic issuers, including:

• the rules under the Exchange Act requiring the filing of quarterly reports on Form 10-Qor current reports on Form 8-K with the SEC;

• the sections of the Exchange Act regulating the solicitation of proxies, consents, orauthorizations in respect of a security registered under the Exchange Act;

• the sections of the Exchange Act requiring insiders to file public reports of their stockownership and trading activities and liability for insiders who profit from trades made ina short period of time;

• the selective disclosure rules by issuers of material nonpublic information underRegulation FD; and

• certain audit committee independence requirements in Rule 10A-3 of the Exchange Act.

We are required to file an annual report on Form 20-F within four months of the end of eachfiscal year. In addition, we intend to publish our results on a quarterly basis through pressreleases, distributed pursuant to the rules and regulations of Nasdaq. Press releases relating tofinancial results and material events will also be furnished to the SEC on Form 6-K. However,the information we are required to file with or furnish to the SEC will be less extensive andless timely compared to that required to be filed with the SEC by U.S. domestic issuers.

In addition, we are permitted by Nasdaq Stock Market Rules to elect to rely, and have electedto rely, on certain exemptions from corporate governance requirements:

• that the board of directors be comprised of a majority of independent directors underNasdaq Rule 5605(b)(1); and

• the requirement that an audit committee be comprised of at least three members underNasdaq Rule 5605(c)(2)(A).

As a result, you may not be afforded the same protections or information, which would be madeavailable to you, were you investing in a U.S. domestic issuer.

Holders of our ADSs may have fewer rights than holders of our Class A ordinary sharesand must act through the depositary to exercise those rights.

Holders of our ADSs do not have the same rights as our shareholders and may only exercisethe voting rights with respect to the underlying Class A ordinary shares represented by theADSs in accordance with the provisions of the deposit agreement. Holders of ADSs may notattend general meetings of our shareholders or cast any votes directly at such meetings. Underthe deposit agreement, ADS holders must vote by giving voting instructions to the depositary.Under our Articles of Association, the minimum notice period required to be given by ourcompany to our registered shareholders for convening a general meeting is 14 days. When ageneral meeting is convened, ADS holders may not receive sufficient advance notice to enablethem to withdraw the Class A ordinary shares underlying their ADSs and become the registeredholder of such shares prior to the record date for the general meeting to allow you to attend thegeneral meeting and to vote directly with respect to any specific matter or resolution which isto be considered and voted upon at the general meeting. In addition, under our Articles ofAssociation, for the purposes of determining those shareholders who are entitled to attend andvote at any general meeting, our directors may close our register of members and/or fix inadvance a record date for such meeting, and such closure of our register of members or thesetting of such a record date may prevent ADS holders from withdrawing the shares underlyingtheir ADSs and becoming the registered holder of such shares prior to the record date, so thatADS holders would not be able to attend the general meeting or to vote directly. Where anymatter is to be put to a vote at a general meeting, the depositary will endeavor to notify ADSholders of the upcoming vote and will arrange to deliver our voting materials to them. Wecannot assure that ADS holders will receive the voting materials in time to ensure that they caninstruct the depositary to vote the shares underlying their ADSs. Furthermore, the depositaryand its agents will not be responsible for any failure to carry out any instructions to vote, forthe manner in which any vote is cast or for the effect of any such vote. As a result, holders ofADSs may not be able to exercise their right to vote and may lack recourse if the underlyingClass A ordinary shares represented by their ADSs are not voted as they requested.

If holders of ADSs do not give instructions to the depositary as to how to vote atshareholders’ meetings, except in limited circumstances, the depositary for our ADSs willgive us a discretionary proxy to vote the Class A ordinary shares underlying their ADSs,which could adversely affect their interests.

Under the deposit agreement for the ADSs, if holders of ADSs do not timely and properly givevoting instructions to the depositary as to how to vote the shares underlying their ADSs at anyparticular shareholders’ meeting, the depositary will give us (or our nominee) a discretionaryproxy to vote the Class A ordinary shares underlying their ADSs at the shareholders’ meetingunless:

• we have failed to timely provide the depositary with notice of meeting and related votingmaterials;

• we have instructed the depositary that we do not wish a discretionary proxy to be given;

• we have informed the depositary that there is substantial opposition as to a matter to bevoted on at the meeting;

RISK FACTORS

– 120 –

• a matter to be voted on at the meeting would have a material adverse impact onshareholders; or

• the voting at the meeting is to be made on a show of hands.

The effect of this discretionary proxy is that if holders of ADSs do not timely and properly givevoting instructions to the depositary as to how to vote the Class A shares underlying their ADSsat any particular shareholders’ meeting, they cannot prevent the Class A ordinary sharesunderlying their ADSs from being voted, except under the circumstances described above. Thismay make it more difficult for holders of ADSs to influence the management of our company.Holders of our ordinary shares are not subject to this discretionary proxy.

You may not receive dividends or other distributions on our ordinary shares and you maynot receive any value for them, if it is illegal or impractical to make them available to you.

The depositary of our ADSs has agreed to pay to you the cash dividends or other distributionsit or the custodian receives on ordinary shares or other deposited securities underlying ourADSs, after deducting its fees and expenses. You will receive these distributions in proportionto the number of ordinary shares your ADSs represent. However, the depositary is notresponsible if it decides that it is unlawful or impractical to make a distribution available to anyholders of ADSs. For example, it would be unlawful to make a distribution to a holder of ADSsif it consists of securities that require registration under the Securities Act but that are notproperly registered or distributed under an applicable exemption from registration. Thedepositary may also determine that it is not feasible to distribute certain property through themail. Additionally, the value of certain distributions may be less than the cost of mailing them.In these cases, the depositary may determine not to distribute such property. We have noobligation to register under U.S. securities laws any ADSs, ordinary shares, rights or othersecurities received through such distributions. We also have no obligation to take any otheraction to permit the distribution of ADSs, ordinary shares, rights or anything else to holders ofADSs. This means that you may not receive distributions we make on our ordinary shares orany value for them if it is illegal or impractical for us to make them available to you. Theserestrictions may cause a material decline in the value of our ADSs.

Conversion of our convertible notes may dilute the ownership interest of existingshareholders.

We issued US$900 million principal amount of convertible senior notes due 2022 in October2017. The conversion of some or all of these notes may dilute the ownership interests ofexisting shareholders. Any sales in the public market of the Class A ordinary shares or ADSsissuable upon such conversion could adversely affect prevailing market prices of our ADSs andClass A ordinary shares. In addition, the existence of the notes may encourage short selling bymarket participants because the conversion of the notes could depress the market prices of ourClass A ordinary shares and ADSs. The prices of our Class A ordinary shares and ADSs couldbe affected by possible sales of our Class A ordinary shares and ADSs by investors who viewthe convertible senior notes as a more attractive means of equity participation in us and byhedging or arbitrage trading activity, which we expect to occur involving our Class A ordinaryshares and ADSs.

RISK FACTORS

Our ADS holders may be subject to limitations on transfer of their ADSs.

In certain cases, our ADSs are transferable on the books of the depositary. However, thedepositary may close its books at any time or from time to time when it deems expedient inconnection with the performance of its duties. The depositary may close its books from timeto time for a number of reasons, including in connection with corporate events such as a rightsoffering, during which time the depositary needs to maintain an exact number of ADS holderson its books for a specified period. The depositary may also close its books in emergencies, andon weekends and public holidays. The depositary may refuse to deliver, transfer or registertransfers of our ADSs generally when our share register or the books of the depositary areclosed, or at any time if we or the depositary thinks it is advisable to do so because of anyrequirement of law or of any government or governmental body, or under any provision of thedeposit agreement, or for any other reason.

We incur increased costs as a result of being a public company.

As a public company, we incur significant legal, accounting and other expenses that we did notincur as a private company. The Sarbanes-Oxley Act of 2002, as well as rules subsequentlyimplemented by the SEC and the Nasdaq, impose various requirements on the corporategovernance practices of public companies. We expect these rules and regulations to increaseour legal and financial compliance costs and to make some corporate activities moretime-consuming and costlier. Operating as a public company will make it more difficult andmore expensive for us to obtain director and officer liability insurance, and we may be requiredto accept reduced policy limits and coverage or incur substantially higher costs to obtain thesame or similar coverage. In addition, we incur additional costs associated with our publiccompany reporting requirements. It may also be more difficult for us to find qualified personsto serve on our board of directors or as executive officers.

We will also incur additional costs as a result of the Listing on the Hong Kong Stock Exchange.We are currently evaluating and monitoring developments with respect to these rules andregulations, and we cannot predict or estimate with any degree of certainty the amount ofadditional costs we may incur or the timing of such costs.

We have been and we may again be involved in class action lawsuits in the United States inthe future. For example, we and certain of our current and former directors and officers werenamed as defendants in two putative securities class actions filed in the United States DistrictCourt for the District of New Jersey: Andrew Goldsmith v. Weibo Corporation. et al., CivilAction No. 2:17-cv-04728-SRC-CLW (filed on June 27, 2017) (“Goldsmith Case”) and FengChen v. Weibo Corporation. et al., Civil Action No. 2:17-cv-05694 (filed on August 3, 2017)(“Chen Case”). The Goldsmith Case was purportedly brought on behalf of a class of personswho allegedly suffered damages as a result of their trading in our ADSs between April 27 andJune 22, 2017; the Chen Case was purportedly brought on behalf of a class of persons whoallegedly suffered damages as a result of their trading in our ADSs between April 28, 2016 andJune 19, 2017. Both cases’ complaints alleged that our company’s public filings containedmaterial misstatements and omissions in violation of the federal securities laws. On September28, 2017, the court entered an order appointing a lead plaintiff and consolidating the two cases.On November 27, 2017, the lead plaintiff filed a consolidated class action complaint. OnJanuary 26, 2018, our company and one individual defendant filed a motion to dismiss theamended complaint. On June 6, 2018, the court granted our motion to dismiss the class actioncomplaint. Such lawsuits could divert a significant amount of our management’s attention andother resources from our business and operations, which could harm our results of operationsand require us to incur significant expenses to defend the lawsuits. Any such class action suit,

RISK FACTORS

– 122 –

whether or not successful, could harm our reputation and restrict our ability to raise capital inthe future. In addition, if a claim is successfully made against us, we may be required to paysignificant damages, which could have a material adverse effect on our financial condition andresults of operations.

Furthermore, our directors and employees may face additional exposure to claims and lawsuitsas a result of their position in other public companies. For example, one of our directors, Mr.Daniel Zhang, was named as a defendant in ongoing putative securities class action lawsuitsfiled in the U.S. against Alibaba Group, a company listed on the New York Stock Exchange(NYSE: BABA), together with certain officers and directors of Alibaba Group, concerning thesuspension of Ant Group’s planned initial public offering and certain antitrust developments,which have subsequently been consolidated. All of these cases concern Mr. Zhang in hiscapacity as the chief executive officer of Alibaba Group. Mr. Zhang was also named as adefendant in ongoing putative securities class action lawsuits filed in the U.S. against anotherU.S. listed company, which remain in their preliminary stages and concern Mr. Zhang in hiscapacity as a director of this U.S. listed company. Mr. Charles Chao, our chairman of the boardof directors, was named as a defendant in ongoing putative securities class action lawsuits filedin the U.S. against another U.S. listed company in connection with a management buyout,which concern Mr. Chao in his capacity as a director of this public company and as an officerof a buyer group member. The securities class action was dismissed on September 29, 2021.On October 20, 2021, plaintiffs informed the court that they would not file an amendedcomplaint. As of the date of this document, plaintiffs have not filed a Notice of Appeal. Theexistence of the litigation, claims, investigations and proceedings against our directors andemployees, even if they do not involve our Company, may harm our reputation and adverselyaffect the trading price of our shares and/or ADSs.

The different characteristics of the capital markets in Hong Kong and the U.S. maynegatively affect the trading prices of our Class A ordinary shares and/or ADSs.

Upon the Listing, we will be subject to Hong Kong and Nasdaq listing and regulatoryrequirements concurrently. The Hong Kong Stock Exchange and Nasdaq have different tradinghours, trading characteristics (including trading volume and liquidity), trading and listingrules, and investor bases (including different levels of retail and institutional participation). Asa result of these differences, the trading prices of our Class A ordinary shares and our ADSsmay not be the same, even allowing for currency differences. Fluctuations in the price of ourADSs due to circumstances peculiar to the U.S. capital markets could materially and adverselyaffect the price of our Class A ordinary shares, or vice versa. Certain events having significantnegative impact specifically on the U.S. capital markets may result in a decline in the tradingprice of our Class A ordinary shares notwithstanding that such event may not impact the tradingprices of securities listed in Hong Kong generally or to the same extent, or vice versa. Becauseof the different characteristics of the U.S. and Hong Kong capital markets, the historical marketprices of our ADSs may not be indicative of the trading performance of our Class A ordinaryshares after the Global Offering.

Exchange between our Class A ordinary shares and our ADSs may adversely affect theliquidity and/or trading price of each other.

Our ADSs are currently traded on Nasdaq. Subject to compliance with U.S. securities law andthe terms of the deposit agreement, holders of our Class A ordinary shares may deposit ClassA ordinary shares with the depositary in exchange for the issuance of our ADSs. Any holderof ADSs may also withdraw the underlying Class A ordinary shares represented by the ADSspursuant to the terms of the deposit agreement for trading on the Hong Kong Stock Exchange.In the event that a substantial number of Class A ordinary shares are deposited with thedepositary in exchange for ADSs or vice versa, the liquidity and trading price of our Class Aordinary shares on the Hong Kong Stock Exchange and our ADSs on the Nasdaq may beadversely affected.

The time required for the exchange between our Class A ordinary shares and ADSs mightbe longer than expected and investors might not be able to settle or effect any sale of theirsecurities during this period, and the exchange of Class A ordinary shares into ADSsinvolves costs.

There is no direct trading or settlement between the Nasdaq and the Hong Kong StockExchange on which our ADSs and our Class A ordinary shares are respectively traded. Inaddition, the time differences between Hong Kong and New York, unforeseen marketcircumstances or other factors may delay the deposit of Class A ordinary shares in exchangefor ADSs or the withdrawal of Class A ordinary shares underlying the ADSs. Investors will beprevented from settling or effecting the sale of their securities during such periods of delay. Inaddition, there is no assurance that any exchange for Class A ordinary shares into ADSs (andvice versa) will be completed in accordance with the timelines that investors may anticipate.

Furthermore, the depositary for the ADSs is entitled to charge holders fees for various servicesincluding for the issuance of ADSs upon deposit of Class A ordinary shares, cancelation ofADSs, distributions of cash dividends or other cash distributions, distributions of ADSspursuant to share dividends or other free share distributions, distributions of securities otherthan ADSs and annual service fees. As a result, shareholders who exchange Class A ordinaryshares into ADSs, and vice versa, may not achieve the level of economic return theshareholders may anticipate.

RISKS RELATING TO THE GLOBAL OFFERING

An active trading market for our Class A ordinary shares on the Hong Kong StockExchange might not develop or be sustained and trading prices of our Class A ordinaryshares might fluctuate significantly.

Following the completion of the Global Offering, we cannot assure you that an active tradingmarket for our Class A ordinary shares on the Hong Kong Stock Exchange will develop or besustained. The trading price or liquidity for our ADSs on the Nasdaq might not be indicativeof those of our Class A ordinary shares on the Hong Kong Stock Exchange following thecompletion of the Global Offering. If an active trading market of our Class A ordinary shareson the Hong Kong Stock Exchange does not develop or is not sustained after the GlobalOffering, the market price and liquidity of our Class A ordinary shares could be materially andadversely affected.

In 2014, the Hong Kong, Shanghai and Shenzhen Stock Exchanges collaborated to create aninter-exchange trading mechanism called Stock Connect that allows international and mainlandChinese investors to trade eligible equity securities listed in each other’s markets through thetrading and clearing facilities of their home exchange. Stock Connect currently covers over2,000 equity securities trading in the Hong Kong, Shanghai and Shenzhen markets. StockConnect allows mainland Chinese investors to trade directly in eligible equity securities listedon the Hong Kong Stock Exchange, known as Southbound Trading; without Stock Connect,mainland Chinese investors would not otherwise have a direct and established means ofengaging in Southbound Trading. In October 2019, the Shanghai and Shenzhen StockExchanges separately announced their amended implementation rules in connection withSouthbound Trading to include shares of WVR companies to be traded through Stock Connect.However, since these rules are relatively new, there remains uncertainty as to theimplementation details, especially with respect to shares of those companies with a secondarylisting on the Hong Kong Stock Exchange. It is unclear whether and when the Class A ordinaryshares of our Company, a WVR company with a secondary listing in Hong Kong upon theListing, will be eligible to be traded through Stock Connect, if at all. The ineligibility or anydelay of our Class A ordinary shares for trading through Stock Connect will affect mainlandChinese investors’ ability to trade our Class A ordinary shares and therefore may limit theliquidity of the trading of our Class A ordinary shares on the Hong Kong Stock Exchange.

During the period between pricing and trading of our Class A ordinary shares inconnection with this offering, the price of our ADSs traded on Nasdaq may fall, whichcould result in a fall in the price of our Class A ordinary shares to be traded on the HongKong Stock Exchange.

The pricing of the Offer Shares will be determined on the Price Determination Date. However,our Class A ordinary shares will not commence trading on the Hong Kong Stock Exchange untilthey are delivered, which is expected to be about four Hong Kong business days after the PriceDetermination Date. As a result, investors may not be able to sell or otherwise deal in our ClassA ordinary shares during that period. Accordingly, holders of our Class A ordinary shares aresubject to the risk that the trading price of our Class A ordinary shares could fall when tradingcommences as a result of adverse market conditions or other adverse developments that couldoccur between the Price Determination Date and the time trading begins. In particular, as ourADSs will continue to be traded on the Nasdaq and their price can be volatile, any fall in theprice of our ADSs may result in a fall in the price of our Class A ordinary shares to be tradedon the Hong Kong Stock Exchange.

There is uncertainty as to whether Hong Kong stamp duty will apply to the trading orconversion of our ADSs following our initial public offering in Hong Kong and the listingof our Class A ordinary shares on the Hong Kong Stock Exchange.

In connection with our initial public offering of Class A ordinary shares in Hong Kong, or theHong Kong IPO, we will establish a branch register of members in Hong Kong, or the HongKong share register. Our Class A ordinary shares that are traded on the Hong Kong StockExchange, including those to be issued in the Hong Kong IPO and those that may be convertedfrom ADSs, will be registered on the Hong Kong share register, and the trading of these ClassA ordinary shares on the Hong Kong Stock Exchange will be subject to the Hong Kong stampduty. To facilitate ADS-ordinary share conversion and trading between the Nasdaq and theHong Kong Stock Exchange, we also intend to move a portion of our issued Class A ordinaryshares from our register of members maintained in the Cayman Islands to our Hong Kong shareregister.

Under the Hong Kong Stamp Duty Ordinance, any person who effects any sale or purchase ofHong Kong stock, defined as stock the transfer of which is required to be registered in HongKong, is required to pay Hong Kong stamp duty. The stamp duty is currently set at a total rateof 0.26% of the greater of the consideration for, or the value of, shares transferred, with 0.13%payable by each of the buyer and the seller. See “Information About this Document and theGlobal Offering — Dealings and Settlement of Class A Ordinary Shares in Hong Kong.”

To the best of our knowledge, Hong Kong stamp duty has not been levied in practice on thetrading or conversion of ADSs of companies that are listed in both the United States and HongKong and that have maintained all or a portion of their ordinary shares, including ordinaryshares underlying ADSs, in their Hong Kong share registers. However, it is unclear whether,as a matter of Hong Kong law, the trading or conversion of ADSs of these dual-listedcompanies constitutes a sale or purchase of the underlying Hong Kong-registered ordinaryshares that is subject to Hong Kong stamp duty. We advise investors to consult their own taxadvisors on this matter. If Hong Kong stamp duty is determined by the competent authority toapply to the trading or conversion of our ADSs, the trading price and the value of yourinvestment in our Class A ordinary shares and/or ADSs may be affected.

Purchasers of our Class A ordinary shares in the Global Offering will experienceimmediate dilution and may experience further dilution if we issue additional Class Aordinary shares in the future.

The initial Public Offer Price of our Class A ordinary shares in Hong Kong is higher than thenet tangible assets per Share of the outstanding Class A ordinary shares issued to our existingshareholders immediately prior to the Global Offering. Therefore, purchasers of our Class Aordinary shares in the Global Offering will experience an immediate dilution in terms of thepro forma net tangible asset value. In addition, we may consider offering and issuing additionalClass A ordinary shares or equity-related securities in the future to raise additional funds,finance acquisitions or for other purposes. Purchasers of our Class A ordinary shares mayexperience further dilution in terms of the net tangible asset value per Share if we issueadditional Class A ordinary shares in the future at a price that is lower than the net tangibleasset value per Share.

In particular, holders of Class A ordinary shares and ADSs should notethat the Hong Kong share registrar will charge between HK$2.50 to HK$20, depending on thespeed of service (or such higher fee as may from time to time be permitted under the HongKong Listing Rules), for each transfer of ordinary shares from one registered owner to another,each share certificate canceled or issued by it and any applicable fee as stated in the sharetransfer forms used in Hong Kong. In addition, holders of ordinary shares and ADSs must payup to US$5.00 (or less) per 100 ADSs for each issuance of ADSs and each cancelation of ADSs,as the case may be, in connection with the deposit of Class A ordinary shares into, orwithdrawal of Class A ordinary shares from, our ADS program.

SUMMARY OF EXEMPTIONS AS A FOREIGN PRIVATE ISSUER IN THE U.S.

As required by Rule 19C.14 of the Hong Kong Listing Rules, set out below is a summary ofthe exemptions from obligations under U.S. securities laws and Nasdaq rules that we enjoy asa foreign private issuer in the U.S.

Exemptions from Nasdaq Rules

Foreign private issuers are permitted to follow home country practice, i.e. for us, the practiceof the Cayman Islands, in lieu of certain corporate governance requirements under Nasdaqlisting standards, as long as they disclose any significant ways in which their corporategovernance practices differ from those required under Nasdaq listing standards and explain thebasis for the conclusion that the exemption is applicable. Specifically, we are currently entitledto rely upon the exemptions from requirements to (i) hold annual shareholders meetings (ii)have a majority of independent directors, and (iii) have an audit committee comprising of atleast three members. Furthermore, because SINA owns more than 50% of the total votingpower of our ordinary shares, we are a “controlled company” under the Nasdaq Rules. We arecurrently entitled to rely on certain exemptions that are available to controlled companies fromNasdaq corporate governance requirements, including the requirements (i) that our directornominees must be selected or recommended solely by independent directors, and (ii) that we

– 135 –

have a corporate governance and nominating committee that is composed entirely ofindependent directors with a written charter addressing the committee’s purpose andresponsibilities. Other than described above, there are no significant differences between ourcorporate governance practices and those followed by U.S. domestic companies under NasdaqRules.

EXEMPTIONS FROM SEC RULES AND REGULATIONS UNDER U.S. FEDERALSECURITIES LAWS

Foreign private issuers are exempted from Regulation FD under the U.S. Exchange Act.Regulation FD provides that when a domestic U.S. issuer, or someone acting on its behalf,discloses material non-public information to certain persons (including securities analysts,other securities market professionals, and holders of the issuer’s securities who couldreasonably be expected to trade on the basis of the information), it must make simultaneouspublic disclosure of that information (in the case of intentional disclosure) or prompt publicdisclosure (in the case of non-intentional disclosure). However, the SEC expects foreignprivate issuers to conduct themselves in accordance with the basic principles underlyingRegulation FD.

Section 16 of the U.S. Exchange Act does not apply to foreign private issuers. Therefore,directors, executive officers and 10% beneficial owners of foreign private issuers are notrequired to file Forms 3, 4 and 5 with the SEC, and are not required to disgorge to the issuerany profits realized from any non-exempt purchase and sale, or non-exempt sale and purchase,of the issuer’s equity securities or security-based swap agreements within a period of less thansix months.

Foreign private issuers are exempt from the SEC’s rules prescribing the furnishing and contentof proxy statements under the U.S. Exchange Act, which specify the procedures and requireddocumentation for soliciting shareholder votes. Accordingly, foreign private issuers are notrequired to disclose certain information in their annual proxy statements, such as whether thework of any compensation consultant has played any role in determining or recommending theform or amount of executive and director compensation has raised a conflict of interest, and,if so, the nature of the conflict and how it is being addressed.

Foreign private issuers are also not required under the U.S. Exchange Act to file periodicreports and financial statements with the SEC as frequently or as promptly as domestic U.S.issuers with securities registered under the U.S. Exchange Act. As a result, our shareholdersmay be afforded less protection than they would under the U.S. Exchange Act rules applicableto domestic U.S. issuers. Unlike domestic U.S. issuers, foreign private issuers are not requiredto file quarterly reports (including quarterly financial information) on Form 10-Q. They alsoare not required to use Form 8-K for current reports, and instead furnish (not file) currentreports on Form 6-K with the SEC.

Annual reports on Form 10-K by domestic U.S. issuers are due within 60, 75, or 90 days afterthe end of the issuer’s fiscal year, depending on whether the company is a “large acceleratedfiler,” a “accelerated filer,” or a “non-accelerated filer.” By contrast, the deadline for foreignprivate issuers to file annual reports on Form 20-F is four months after the end of their fiscalyear.

OUR ARTICLES OF ASSOCIATION

We are an exempted company incorporated in the Cayman Islands with limited liability and ouraffairs are governed by our Memorandum and Articles of Association, the Cayman CompaniesAct and the common law of the Cayman Islands.

The laws of Hong Kong differ in certain respects from the Cayman Companies Act, and ourArticles of Association are specific to us and include certain provisions that may be differentfrom common practices in Hong Kong. For example:

(a) Rule 19C.07 of the Hong Kong Listing Rules provides that the Hong Kong StockExchange will consider that an issuer such as our Company seeking a listing underChapter 19C has met the requirements of Rule 19.30(1)(b) of the Hong Kong ListingRules for standards of shareholder protection if it has met the shareholder protectionstandards by reference to eight criteria set out in Rule 19C.07.

(b) Rule 19C.07(3) of the Hong Kong Listing Rules requires the appointment, removal andremuneration of auditors to be approved by a majority of a Qualifying Issuer’s (as definedin the Hong Kong Listing Rules) members or other body that is independent of theissuer’s board of directors, but our Articles of Association do not contain this or a similarprovision.

(c) Pursuant to Rule 19C.07(6) of the Hong Kong Listing Rules, a member must abstain fromvoting to approve a matter in circumstances required by the Hong Kong Listing Rules. Weundertake to put forth a resolution at the next general meeting of our Company to reviseour Articles of Association so that a member’s right to vote is subject to the Hong KongListing Rules.

(d) Rule 19C.07(7) of the Hong Kong Listing Rules requires that members holding a minorityshareholding in an issuer’s total number of issued shares must be able to requisition anextraordinary general meeting and add resolutions to a meeting agenda. The minimumstake required to do so must not be higher than 10% of the voting rights, on a one voteper share basis, in the share capital of the of the issuer, while the minimum stake set outin our Articles of Association is not less than one-third of the votes attaching to all issuedand outstanding Shares. We undertake to put forth resolutions at the next general meetingof our Company to revise our Articles of Association, so that (i) the minimum stakerequired to convene an extraordinary general meeting and add resolutions to a meetingagenda will be one-tenth of the voting rights, on a one vote per share basis, in the sharecapital of our Company; and (ii) the quorum for a general meeting of our Company willbe lowered from the current one or more shareholders holding at least one-third of theaggregate voting power of our Company to one or more shareholders holding at leastone-tenth of the aggregate voting power of our Company. We have obtained anirrevocable undertaking from our controlling shareholder prior to the Listing to be presentand vote in favor of the proposed resolutions outlined above with a view to ensuring thatthere may be adequate quorum and votes in favor of such resolutions.

See “Waivers and Exemptions” in this document and “Summary of our Constitution andCayman Company Law” as set out in Appendix III to this document for further details.

As we are seeking a listing as a Grandfathered Greater China Issuer pursuant to Chapter 19C(Secondary Listings of Qualifying Issuers) of the Hong Kong Listing Rules with a WVRstructure, certain shareholder protection measures and governance safeguards under Chapter8A (Weighted Voting Rights) of the Hong Kong Listing Rules do not apply to us pursuant toRule 19C.12 of the Hong Kong Listing Rules and our Articles differ from Chapter 8A in anumber of ways. Material differences in shareholder protection and corporate governancesafeguards are set out below:

Requirements under Chapter 8A ofthe Hong Kong Listing Rules Our weighted voting rights structure

Rule 8A.13 of the Hong Kong Listing Rulesprohibits the increase in the proportion ofshares with WVRs after the Listing.

Our Articles do not contain such restrictionson the Class B ordinary shares.

Rule 8A.15 of the Hong Kong Listing Rulesrequires that, where there is a reduction in thenumber of issued shares, the weighted votingrights must be reduced proportionately.

Rule 8A.17 of the Hong Kong Listing Rulesrequire cessation of weighted voting rights if(i) the beneficiary is deceased; (ii) no longer amember of the issuer’s board of directors; (iii)deemed by the Hong Kong Stock Exchange tobe incapacitated for the purpose of performinghis or her duties as a director; or (iv) deemedby the Hong Kong Stock Exchange to nolonger meet the requirements of a director setout in the Hong Kong Listing Rules.

Subject to the provisions of our Articles ofAssociation, each Class B ordinary share isconvertible into one Class A ordinary share atany time by the shareholder. If at any timeSINA Corporation and its affiliates inaggregate hold less than 5% of the totalnumber of issued and outstanding Class Bordinary shares, each issued and outstandingClass B ordinary shares will be automaticallyand immediately converted into one Class Aordinary shares, and no Class B ordinaryshares could be issued by us thereafter. TheClass B ordinary shares will be automaticallyand immediately converted into an equalnumber of Class A ordinary share upon anysale, transfer, assignment or disposition of theClass B ordinary shares by the holder of ClassB ordinary shares to any person or entitywhich is not an affiliate of such holder.

Rule 8A.18(1) of the Hong Kong ListingRules requires weighted voting rightsattached to a beneficiary’s shares to ceaseupon transfer to another person of thebeneficial ownership of, or economic interestin, those shares or the control over the votingrights attached to them (through votingproxies or otherwise).

Requirements under Chapter 8A ofthe Hong Kong Listing Rules Our weighted voting rights structure

Rule 8A.18(2) of the Hong Kong ListingRules states that a limited partnership, trust,private company or other vehicle may holdshares carrying weighted voting rights onbehalf of a beneficiary of weighted votingrights, provided that such an arrangementdoes not result in a circumvention of Rule8A.18(1) of the Hong Kong Listing Rules.

Furthermore, we will make certain changes tothe Articles at the upcoming general meetingto the effect that, if the Class B ordinaryshares are no longer under the control of theexisting WVR beneficiaries or their affiliates,all of the relevant Class B ordinary sharesheld by it shall be automatically convertedinto Class A ordinary shares. For furtherdetails, see the section headed “Waivers andExemptions – Shareholder ProtectionRequirements – Other Proposed Amendmentsto the Articles”.

Under Rule 8A.23 of the Hong Kong ListingRules, non-WVR shareholders must be able toconvene an extraordinary general meeting andadd resolutions to the meeting agenda. Theminimum stake required to do so must not behigher than 10% of the voting rights on a onevote per share basis in the share capital of thelisted issuer.

The minimum stake as currently set out in ourArticles of Association is different from therequirement. For further details, see sectionheaded “Waivers and Exemptions –Shareholder Protection Requirements –Requisition of Extraordinary General Meetingby Shareholders”.

Rule 8A.24 of the Hong Kong Listing Rulesrequires weighted voting rights to bedisregarded on any resolution to approvecertain matters, including (i) changes to thelisted issuer’s constitutional documents,however framed; (ii) variation of rightsattached to any class of shares; (iii) theappointment or removal of an independentnon-executive director; (iv) the appointmentor removal of auditors; and (v) the voluntarywinding-up of the listed issuer.

Under our weighted voting rights structure,each Class B ordinary share entitles the holderto exercise three votes on all matters subjectto the vote at general meetings of ourCompany.

Rule 8A.30 of the Hong Kong Listing Rulesrequires issuer with a WVR structure mustestablish a Corporate Governance Committeewith at least the terms of reference set out inCode Provision D.3.1 of Appendix 14 to theHong Kong Listing Rules and additionalterms as set out under Rule 8A.30 of the HongKong Listing Rules.

PRINTED CORPORATE COMMUNICATIONS

Rule 2.07A of the Hong Kong Listing Rules provides that a listed issuer may send or otherwisemake available to the relevant holders of its securities any corporate communication byelectronic means, provided that either the listed issuer has previously received from each of therelevant holders of its securities an express, positive confirmation in writing or theshareholders of the listed issuer have resolved in a general meeting that the listed issuer maysend or supply corporate communications to shareholders by making them available on thelisted issuer’s own website or the listed issuer’s constitutional documents contain provision tothat effect, and certain conditions are satisfied.

Our ADSs have been listed on the Nasdaq since April 2014. We have a diverse shareholder basewith ADS holders globally.

We do not currently produce or send out any corporate communications to our shareholders orholders of ADSs in printed form unless requested or in limited circumstances. We publicly fileor furnish various corporate communications with the SEC which are posted on the SEC’swebsite. Our annual reports on Form 20-F and current reports on Form 6-K and all amendmentsto these reports are also available free of charge on our website as soon as reasonablypracticable after they are filed with or furnished to the SEC. Further, we will post our proxymaterials and notices to our shareholders and holders of ADSs on a publicly accessible website.Those documents will also be available on our website.

WAIVERS AND EXEMPTIONS

– 144 –

Apart from the Hong Kong Offer Shares that we will offer for subscription by the public inHong Kong, the International Offer Shares will be placed to professional, institutional,corporate and other investors in Hong Kong and elsewhere in the world. Given our diverseshareholder base and the potential number of countries in which our shareholders are located,we consider that it would not be practicable for us to send printed copies of all our corporatecommunications to all of our shareholders. Further, we consider that it would also not bepracticable for us to approach our existing shareholders individually to seek confirmation fromthem of their wish to receive corporate communications in electronic form, or to provide themwith the right to request corporate communications in printed form instead.

We have applied for, and the Hong Kong Stock Exchange has granted, a waiver from strictcompliance with Rule 2.07A of the Hong Kong Listing Rules on the conditions that we will:

(a) issue all future corporate communications as required by the Hong Kong Listing Rules onour own website in English and Chinese, and on the Hong Kong Stock Exchange’swebsite in English and Chinese;

(b) provide printed copies of proxy materials in English to our shareholders at no costs uponrequest; and

(c) ensure that the “Investor Relations” page of our website (http://ir.weibo.com/) will directinvestors to all of our future filings with the Hong Kong Stock Exchange.

ACQUISITION AFTER THE TRACK RECORD PERIOD

Pursuant to Rules 4.04(2) and 4.04(4)(a) of the Hong Kong Listing Rules, the accountant’sreport to be included in a listing document must include the income statements and balancesheets of any subsidiary or business acquired, agreed to be acquired or proposed to be acquiredsince the date to which its latest audited accounts have been made up in respect of each of thethree financial years immediately preceding the issue of the listing document.

Acquisition since June 30, 2021

Since the end of Track Record Period, we have completed an acquisition up to the LatestPracticable Date (the “Acquisition”). Details of the Acquisition up to the Latest PracticableDate include:

Target Consideration(1) Percentage of interest acquired

Principalbusinessactivities

(approximatelyRMB million)

Business A(2) ���������� 200 100% E-sports team

Notes:

(1) The approximate consideration disclosed in the table represents the consideration for the Acquisition after theTrack Record Period.

(2) None of the core connected persons at the level of our Company has a controlling interest in the target.

WAIVERS AND EXEMPTIONS

– 145 –

The consideration for the Acquisition was arrived at after commercial arm’s lengthnegotiations, based on factors including market dynamics, a mutually agreed valuation, andcapital required for the target company’s operations.

Our directors believe that the Acquisition will complement our Group’s businesses and aretherefore expected to create synergies. Accordingly, our directors believe that the Acquisition,if consummated, will be fair and reasonable and in the interests of the Shareholders as a whole.The consideration for the Acquisition, if consummated, will be satisfied by our Group’s ownsource of funds. For the avoidance of doubt, the proceeds of the Global Offering will not beused to fund the Acquisition.

Conditions for granting the waiver and its scope in respect of the Acquisition

We have applied for, and the Hong Kong Stock Exchange has granted, a waiver from strictcompliance with Rules 4.04(2) and 4.04(4)(a) of the Hong Kong Listing Rules in respect of theAcquisition on the following grounds:

The percentage ratios of the Acquisition are all less than 5% by reference to the most recentfiscal year of our Track Record Period

The relevant percentage ratios calculated in accordance with Rule 14.07 of the Hong KongListing Rules for the Acquisition are all less than 5% by reference to the most recent fiscal yearof the Track Record Period.

Accordingly, we believe that the Acquisition has not resulted in, or is not expected to result in,any significant changes to our financial position since June 30, 2021, and all information thatis reasonably necessary for the potential investors to make an informed assessment of ouractivities or financial position has been included in this document. As such, we consider thata waiver from compliance with Rules 4.04(2) and 4.04(4)(a) of the Hong Kong Listing Ruleswould not prejudice the interests of the investors.

The historical financial information of the target is not readily available

The Company confirms that the target of the Acquisition does not have available historicalfinancial information which is readily available. In particular, the target of the Acquisition isan E-sports team and it did not have any historical cash flow or profit and loss statementsavailable for inclusion in this document.

In addition, having considered the Acquisition to be immaterial and that we do not expect theAcquisition to have any material effect on our business, financial condition or operations, webelieve that it would not be meaningful and would be unduly burdensome for us to prepare andinclude the financial information of the target during the Track Record Period in this document.As we do not expect the Acquisition to result in any material changes to our financial positionafter the Track Record Period, we do not believe the non-disclosure of the required informationpursuant to Rules 4.04(2) and 4.04(4)(a) of the Hong Kong Listing Rules would prejudice theinterests of the investors.

Alternative disclosure of the Acquisition in this document

We have provided alternative information about the Acquisition in this document. Suchinformation includes those which would be required for a discloseable transaction underChapter 14 of the Hong Kong Listing Rules that our directors consider to be material,including, for example, descriptions of the target’s principal business activities, the investmentamounts, and a statement as to whether the core connected persons at the level of our Companyis a controlling shareholder of the target. We have however excluded disclosure on the nameof the target in connection with the Acquisition as the Company has entered into confidentialityagreement with the acquisition target and there is no consent for such disclosure. Since therelevant percentage ratio of the Acquisition is less than 5% by reference to the most recentfiscal year of the Track Record Period, we believe the current disclosure is adequate forpotential investors to form an informed assessment of us. We do not expect to use any proceedsfrom the Listing to fund the Acquisition.

DISCLOSURE REQUIREMENTS RELATING TO THE ACCOUNTANT’S REPORT

Rules 4.04(3)(a), 4.05(2) and 4.13 of the Hong Kong Listing Rules and Paragraph 31(3)(b) ofthe Third Schedule to the Companies (Winding Up and Miscellaneous Provisions) Ordinanceset out certain historical financial information to be included in a listing document that is notrequired to be disclosed under U.S. GAAP, including in particular:

(i) balance sheet at a company level;

(ii) aging analysis of accounts receivables;

(iii) aging analysis of accounts payables; and

(iv) adjustments made to show profits of all periods in accordance with the relevantaccounting standards in relation to the last fiscal year reported on.

In accordance with U.S. GAAP, we have applied the modified retrospective method to accountfor the impact of the adoption of certain new accounting standards in the Track Record Period.Under the modified retrospective method adopted by our Group, comparative periods in thelatest consolidated financial statements are not retrospectively adjusted.

During the Track Record Period, we have adopted, among other new accounting standards thatdid not have a material impact on the Group’s consolidated financial statements, AccountingStandards Update 2016-13 “Financial Instruments – Credit Losses (Topic 326): Measurementof Credit Losses on Financial Instruments”, or ASC Topic 326, and Accounting StandardsUpdate 2016-02 “Leases (Topic 842)”, including certain transitional guidance and subsequentamendments, or ASC 842. The relevant accounting policies upon the adoption of these newaccounting standards are disclosed in the “Accountant’s Report” in Appendix IA.

ASC Topic 326 was adopted on January 1, 2020 which amends previously issued guidanceregarding the impairment of financial instruments by creating an impairment model that isbased on expected losses. ASC Topic 326 does not permit a full retrospective approach andcomparative prior periods should not be adjusted. The adoption had no material impact to thebeginning retained earnings on January 1, 2020.

WAIVERS AND EXEMPTIONS

– 147 –

ASC 842 was adopted on January 1, 2019 using the modified retrospective method by applyingthe new lease standard to all leases existing as of January 1, 2019, the date of initialapplication, and no adjustments were made to the comparative periods. Adoption of the newlease standard resulted in the recognition of US$14.4 million of operating lease asset andUS$14.9 million of operating leasing liability on the consolidated balance sheet as of January1, 2019, and no impact to the beginning retained earnings on January 1, 2019.

The following alternative disclosures with respect to certain items identified above which arerelevant to us have been included in this document: (a) for certain new accounting standardsthat came into effect in the latest fiscal year, the accounting policies as well as the impact ofadoption, if any, to the beginning accumulated deficit of initial application (i.e., January 1,2019 and 2020) has been disclosed in the “Accountant’s Report” in Appendix IA in accordancewith the relevant requirements under U.S. GAAP; and (b) disclosure of the relevant accountingpolicies adopted for the Track Record Period in the “Accountant’s Report” in Appendix IA.

As this document has included the above alternative disclosures and the current disclosure inthis document contains all information which is necessary for the investors to make aninformed assessment of the business, asset and liability, financial position, trading position,management and prospect of our Group, we believe that it would be of no material value to theHong Kong investors and be unduly burdensome for the Accountant’s Report in Appendix IAto this document to include certain required information pursuant to Rules 4.04(3)(a), 4.05(2)and 4.13 of the Hong Kong Listing Rules and Paragraph 31(3)(b) of the Third Schedule to theCompanies (Winding Up and Miscellaneous Provisions) Ordinance and that the non-disclosureof such information will not prejudice the interests of investors.

We have applied for, and the Hong Kong Stock Exchange has granted, a waiver from the HongKong Stock Exchange to us from strict compliance with the requirements under Rules4.04(3)(a), 4.05(2) and 4.13 of the Hong Kong Listing Rules. We have applied for, and the SFChas granted, an exemption to us from strict compliance with the requirements under Paragraph31(3)(b) of the Third Schedule to the Companies (Winding Up and Miscellaneous Provisions)Ordinance, to the extent not strictly met by the current disclosure in this document. The SFCexemption referred to above shall be granted on the conditions that: (i) the particulars of suchexemption are set out in this document; and (ii) this document will be issued on or beforeNovember 29, 2021.

DEALINGS IN SHARES PRIOR TO LISTING

According to Rule 9.09(b) of the Hong Kong Listing Rules, there must be no dealing in thesecurities of a new applicant for which listing is sought by any core connected person of theissuer from four clear business days before the expected hearing date until listing is granted(the “Relevant Period”).

We had approximately 70 subsidiaries (including the Company’s consolidated affiliatedentities) as of June 30, 2021, and our ADSs are widely held, publicly traded and listed on theNasdaq. We consider that we are therefore not in a position to control the investment decisionsof our shareholders or the investing public in the US.

Solely based on public filings with the SEC as of the Latest Practicable Date, other than SINACorporation and Ali WB Investment Holding Limited (“Ali WB”), a wholly-owned subsidiaryof Alibaba Group, we had no shareholders who was not a director and held 10% or more of ourissued share capital.

For a company whose securities are listed and traded in the U.S., we note that it is a commonpractice for substantial shareholders and corporate insiders, including directors, executives andother members of management, to set up trading plans that meet the requirements of Rule10b5-1 under the U.S. Exchange Act (the “Rule 10b5-1 Plan(s)”) to buy or sell the company’ssecurities. A Rule 10b5-1 Plan is a written plan, set up with a broker, to trade securities that(a) is entered into at a time when the person trading the securities is not aware of any materialnon-public information; (b) specifies the amount of securities to be purchased or sold and theprice at which and the date on which the securities were to be purchased or sold; and (c) doesnot allow the person trading the securities to exercise any subsequent influence over how,when, or whether to effect purchases or sales. Persons who trade securities pursuant to a Rule10b5-1 Plan have an affirmative defense against insider trading allegations under U.S.securities law.

On the basis of the above, we consider that the following categories of persons (collectively,the “Permitted Persons”) should not be subject to the dealing restrictions set out in Rule9.09(b) of the Hong Kong Listing Rules:

(a) Mr. Charles Chao, our chairman of the board of directors since our inception and whocontrols our Company through SINA, in respect of (i) his use of the Shares as security(including, for the avoidance of doubt, using Shares as security in connection withentering into financing transactions during the Relevant Period as well as satisfying anyrequirements to top-up security under the terms of financing transactions entered intoprior to the Relevant Period), provided that there will be no change in the beneficialownership of the Shares at the time of entering into any such transactions during theRelevant Period and (ii) his dealings pursuant to Rule 10b5-1 Plans that have been set upprior to the Relevant Period (“Category 1”);

(b) the directors and chief executives of our Company other than Mr. Charles Chao, and thedirectors and chief executives of our Major Subsidiaries, in respect of (i) their respectiveuse of the Shares as security (including, for the avoidance of doubt, using Shares assecurity in connection with entering into financing transactions during the RelevantPeriod as well as satisfying any requirements to top-up security under the terms offinancing transactions entered into prior to the Relevant Period), provided that there willbe no change in the beneficial ownership of the Shares at the time of entering into anysuch transactions during the Relevant Period and (ii) the respective dealings pursuant toRule 10b5-1 Plans that have been set up prior to the Relevant Period (“Category 2”);

(c) directors, chief executives and substantial shareholders of our non-Major Subsidiaries andtheir close associates (“Category 3”); and

(d) any other person (whether or not an existing Shareholder) who may, as a result ofdealings, become our substantial shareholder (as defined in the Hong Kong Listing Rules)and who is not its director or chief executive, or a director or chief executive of oursubsidiaries, or their close associates (“Category 4”).

For the avoidance of doubt:

(a) as the foreclosure, enforcement or exercise of other rights by the lenders in respect of asecurity interest over the Shares (including, for the avoidance of doubt, any securityinterest created pursuant to any top-up of security) will be subject to the terms of thefinancing transaction underlying such security and not within the control of the pledgor,

any change in the beneficial owner of the Shares during the Relevant Period resultingfrom the foreclosure, enforcement or exercise of other rights by the lenders in respect ofsuch security interest will not be subject to Rule 9.09(b) of the Hong Kong Listing Rules;and

(b) persons in Category 1 and Category 2 who use their respective Shares other than asdescribed in this section headed “— Dealings in the Shares prior to Listing” are subjectto the restrictions under Rule 9.09(b) of the Hong Kong Listing Rules.

We believe, subject to the conditions set forth below, the dealings in our securities by our coreconnected persons will not prejudice the interests of the potential investors of our Companyand align with the principles in the Hong Kong Stock Exchange’s Guidance Letter GL42-12.

We have applied for, and the Hong Kong Stock Exchange has granted, a waiver from strictcompliance with Rule 9.09(b) of the Hong Kong Listing Rules subject to the followingconditions:

(a) Categories 1 and 2 of the Permitted Persons who entered into Rule 10b5-1 Plans have nodiscretion over dealings in our ADSs after the plans have been entered into; whereCategories 1 and 2 of the Permitted Persons use the Shares as security, there will be nochange in the beneficial ownership of the Shares at the time of entering into the relevanttransactions during the Relevant Period;

(b) Categories 3 and 4 of the Permitted Persons do not have any influence over the GlobalOffering and do not possess any of our non-public inside information given that suchpersons are not in a position with access to information that is considered material to ustaken as a whole. Given the large number of our subsidiaries (including our consolidatedaffiliated entities) and our vast ADS holder base, we and our management do not haveeffective control over the investment decisions of Categories 3 and 4 of the PermittedPersons in our ADSs;

(c) we will promptly release any inside information to the public in the United States andHong Kong in accordance with the relevant laws and regulations of the U.S. (includingthe Nasdaq rules) and Hong Kong. Accordingly, the Permitted Persons (other thanCategory 1 and Category 2 persons) are not in possession of any non-public insideinformation of which we are aware;

(d) we will notify the Hong Kong Stock Exchange of any breaches of the dealing restrictionsby any of our core connected persons during the Relevant Period when we become awareof the same other than dealings by the core connected persons who are Permitted Personswithin the permitted scopes set out above; and

(e) prior to the Listing Date, other than within the permitted scopes set out above, ourdirectors and chief executive and the directors and chief executives of our MajorSubsidiaries and their close associates will not deal in the Shares or the ADSs during theRelevant Period provided that such prohibited dealing in the Shares shall not include thegranting, vesting, payment or exercise (as applicable) of RSUs, incentive and non-statutory options, restricted shares, dividend equivalents, and share payments under ourGroup’s share incentive plans.

MONTHLY RETURN

Rule 13.25B of the Hong Kong Listing Rules requires a listed issuer to publish a monthlyreturn in relation to movements in our equity securities, debt securities and any othersecuritized instruments, as applicable, during the period to which the monthly return relates.

Under the Joint Policy Statement, this common waiver is subject to the condition that the issuercan meet one of the following three conditions:

(a) it has received a relevant partial exemption from Part XV of the SFO; or

(b) it publishes a “next day disclosure return” in strict compliance with Rule 13.25A of theHong Kong Listing Rules, regardless of the waiver of general effect from this Rule forsecondary listed issuers; or

(c) it is subject to overseas laws or regulations that have a similar effect to Rule 13.25B ofthe Hong Kong Listing Rules and any differences are not material to shareholderprotection.

As we have obtained a partial exemption from strict compliance with Part XV of the SFO fromthe SFC, we have applied for, and the Hong Kong Stock Exchange has granted, a waiver fromstrict compliance with the continuing obligations under Rule 13.25B of the Hong Kong ListingRules. We will disclose information about share repurchases, if material, in our quarterlyearnings releases and annual reports on Form 20-F which are furnished or filed with the SECin accordance with the applicable U.S. rules and regulations.

SHAREHOLDER PROTECTION REQUIREMENTS

For an overseas issuer seeking a secondary listing on the Hong Kong Stock Exchange, Rule19.30(1)(b) of the Hong Kong Listing Rules requires the overseas issuer’s primary listing is oris to be on an exchange where the standards of shareholder protection are at least equivalentto those provided in Hong Kong. Rule 19C.06 of the Hong Kong Listing Rules provides thatAppendices 3 and 13 to the Hong Kong Listing Rules do not apply to an overseas issuer thatis a Non-Greater China Issuer (as defined in the Hong Kong Listing Rules) or a GrandfatheredGreater China Issuer seeking a secondary listing under Chapter 19C of the Hong Kong ListingRules. Rule 19C.07 of the Hong Kong Listing Rules provides that the Hong Kong StockExchange will consider that a Grandfathered Greater China Issuer seeking a secondary listinghas met the requirements of Rule 19.30(1)(b) of the Hong Kong Listing Rules if it has met theshareholder protection standards by reference to eight criteria set out in Rule 19C.07 of theHong Kong Listing Rules.

We are a Grandfathered Greater China Issuer under Chapter 19C of the Hong Kong ListingRules.

Approval, Removal and Remuneration of Auditors

Rule 19C.07(3) of the Hong Kong Listing Rules requires the appointment, removal andremuneration of auditors to be approved by a majority of the Qualifying Issuer’s (as definedin the Hong Kong Listing Rules) members or other body that is independent of the issuer’sboard of directors (the “Auditors Provision”).

Our Articles do not contain an equivalent Auditors Provision. Pursuant to our Articles, ourboard has the power to appoint, remove and remunerate the auditors instead. Although theboard has such a power, it has formally delegated this function to our audit committee (the“Audit Committee”) since our listing on the Nasdaq in April 2014.

The Audit Committee is akin to an independent body of the board on the basis of theindependence requirements set out in applicable U.S. laws and the Nasdaq rules. The AuditCommittee comprises of three members, all of whom are independent directors as required bythe U.S. Exchange Act and applicable Nasdaq rules.

We have applied for, and the Hong Kong Stock Exchange has granted, a waiver from strictcompliance with the requirements of Rule 19C.07(3) of the Hong Kong Listing Rules.

Annual General Meeting

Rule 19C.07(4) of the Hong Kong Listing Rules requires a general meeting to be held each yearas the Qualifying Issuer’s annual general meeting. The Articles currently provide that theCompany shall in each year hold a general meeting as its annual general meeting. Accordingly,the Company has convened an annual general meeting for each year during the Track RecordPeriod.

We will amend the Articles at the upcoming general meeting to comply with Rule 19C.07(4)of the Hong Kong Listing Rules (the “AGM Provision”) to the effect that we must hold anannual general meeting each year.

Prior to the amendment to the Articles and the AGM Provision being adopted, the Companyundertakes to hold an annual general meeting within six months after the end of each financialyear with effect from Listing to be in compliance with Rule 13.46(2)(b) of the Hong KongListing Rules. As advised by the Company’s legal adviser as to the laws of Cayman Islands,the Company’s undertaking to convene an annual general meeting within the period of sixmonths after the end of each financial year with effect from the Listing pursuant to Rule13.46(2)(b) does not conflict with or result in a breach of any of the terms or provisions of theCompany’s existing Memorandum and Articles or any law, public rule or regulation applicableto the Company currently in force in the Cayman Islands.

Requisition of Extraordinary General Meeting by Shareholders

Rule 19C.07(7) of the Hong Kong Listing Rules requires that members holding a minorityshareholding in an issuer’s total number of issued shares to be able to requisition anextraordinary general meeting and add resolutions to a meeting agenda. The minimum stakerequired to do so must not be higher than 10% of the voting rights, on a one vote per sharebasis, in the share capital of the issuer, while the minimum stake as currently set out in theArticles is not less than one-third of the votes attaching to all issued and outstanding Shares.In addition, the Articles currently provide that quorum for a general meeting of the Companyshall be one or more members holding shares which represent, in aggregate, not less thanone-third of the total voting power of the outstanding shares of the Company that are entitledto vote at the meeting.

We have identified seven entities as our Major Subsidiaries. For further details, see the sectionheaded “History and Corporate Structure — Corporate Structure — Major Subsidiaries”. Wehad approximately 70 subsidiaries (including our consolidated affiliated entities) as of June 30,2021. We believe that it would be unduly burdensome for us to disclose this information inrespect of all of our subsidiaries (including our consolidated affiliated entities) as we wouldhave to incur additional costs and devote additional resources in compiling and verifying therelevant information for such disclosure, which would not be material or meaningful toinvestors.

The Major Subsidiaries include all of our subsidiaries (including our consolidated affiliatedentities) that meet the financial threshold for “significant subsidiaries” under Regulation S-Xin the U.S. (i.e., contributing more than 10% of (a) our Group’s total assets or (b) our Group’stotal net revenues and income or loss from continuing operations before income taxes (afterintercompany eliminations) attributable to the controlling interest to the absolute value of suchconsolidated income or loss) and are representative of our business (including those that holdmajor assets, intellectual property rights, proprietary technologies and R&D).

As of September30, 2021, the total number of shares underlying outstanding options and restricted share unitsgranted pursuant to the Share Incentive Plans represent only 3.2% of our Company’s totalissued share capital.

The U.S. Exchange Act and the rules and regulations promulgated thereunder requiredisclosure of interests by shareholders that are broadly equivalent to Part XV of the SFO.Relevant disclosure in respect of the substantial shareholder’s interests can be found in “MajorShareholders”.

We have applied for, and the Hong Kong Stock Exchange has granted, a waiver from strictcompliance with Paragraphs 41(4) and 45 of Part A of Appendix 1 and Practice Note 5 to theHong Kong Listing Rules on the following conditions:

WAIVERS AND EXEMPTIONS

– 158 –

(a) the SFC granting us and our shareholders a partial exemption from strict compliance withPart XV of the SFO;

(b) we will file with the Hong Kong Stock Exchange, as soon as practicable, any declarationof shareholding and securities transactions filed with the SEC; and

(c) we will disclose in present and future listing documents any shareholding interests asdisclosed in an SEC filing and the relationship between our directors, officers, membersof committees and their relationship to any controlling shareholders.

DISCLOSURE OF OFFER PRICE

Paragraph 15(2)(c) of Part A of Appendix 1 to the Hong Kong Listing Rules provides that theissue price or offer price of each security must be disclosed in the listing document.

The Public Offer Price will be determined by reference to, among other factors, the closingprice of our ADS price on the Nasdaq on the last trading date on or before the pricedetermination date and we have no control on the market price of our ADSs traded on theNasdaq. Given the ADSs of our Company are freely tradable on the Nasdaq, there may be pricefluctuations in the ADSs as a result of market volatility and other factors during the periodfrom the bulk-printing of this document until the pricing of the Global Offering.

Setting a fixed price or a price range with a low end offer price per Offer Share may adverselyaffect the market price of the ADSs and the Hong Kong Offer Shares considering, among otherfactors, that this may indicate an arbitrary floor price and may potentially prejudice our abilityto price in the best interest of our Company and our Shareholders.

A maximum Public Offer Price will be disclosed in this document and the Green ApplicationForm. This alternative disclosure approach would not prejudice the interests of the investingpublic in Hong Kong.

Given in no circumstances will the Public Offer Price for the Hong Kong Offer Shares begreater than the maximum Public Offer Price as stated in this document and the GreenApplication Form, the disclosure of the maximum Public Offer Price in this document will bein compliance with the requirement to disclose the “amount payable on application andallotment on each share” as required by paragraph 9 of the Third Schedule of the Companies(Winding Up and Miscellaneous Provisions) Ordinance.

Sufficient disclosure in relation to this alternative pricing mechanism will be disclosed in therelevant sections of this document, which will provide Hong Kong investors with sufficientinformation to form informed decisions of their investment.

SUBSCRIPTION FOR SHARES BY EXISTING SHAREHOLDERS

Rule 2.03(2) of the Hong Kong Listing Rules provides that the issue and marketing ofsecurities should be conducted in a fair and orderly manner.

Rule 10.04 of the Hong Kong Listing Rules requires that existing shareholders may onlysubscribe for or purchase any securities for which listing is sought that are being marketed byor on behalf of a new applicant either in his/her/its own name or through nominees if theconditions in Rule 10.03 of the Hong Kong Listing Rules are fulfilled. Paragraph 5(2) ofAppendix 6 to the Hong Kong Listing Rules states that, without the prior written consent of

WAIVERS AND EXEMPTIONS

– 159 –

the Hong Kong Stock Exchange, no allocations will be permitted to be made to directors,existing shareholders of a listing applicant or their close associates, unless the conditions setout in Rules 10.03 and 10.04 of the Hong Kong Listing Rules are fulfilled.

The conditions in Rules 10.03(1) and (2) of the Hong Kong Listing Rules are as follows:

(i) that no securities are offered to the purchasers on a preferential basis and no preferentialtreatment is given to them in the allocation of the securities; and

(ii) that the minimum prescribed percentage of public shareholders required by Rule 8.08(1)of the Hong Kong Listing Rules is achieved.

Rule 19.31 of the Hong Kong Listing Rules provides that the requirement under Rule 8.08 ofthe Hong Kong Listing Rules to maintain a minimum percentage of public shareholders doesnot apply to a secondary listing.

The Hong Kong Stock Exchange’s Guidance Letter HKEX-GL85-16 provides that the HongKong Stock Exchange will consider granting a waiver from Rule 10.04 of the Hong KongListing Rules and consent, pursuant to Paragraph 5(2) of Appendix 6 to the Hong Kong ListingRules, allowing an applicant’s existing shareholders or their close associates to participate inan initial public offering if any actual or perceived preferential treatment arising from theirability to influence the applicant during the allocation process can be addressed.

Our Company has been listed on the Nasdaq since April 2014 and has a wide and diverseshareholder base. There is a robust level of trade in our Company’s securities, with significantdaily trading volume resulting in daily changes to our existing shareholders. As a companylisted on the Nasdaq, we are not in a position to prevent any person or entity from acquiringour listed securities prior to the allocation of shares in connection with the Global Offering. Itwould therefore be unduly burdensome for us to seek the prior consent of the Hong Kong StockExchange for each of our existing shareholders or their close associates who subscribe forShares in the Global Offering.

Since we do not require shareholders’ approval in order to proceed with the Global Offering,any persons (other than its directors and senior management, SINA Corporation and Ali WB)who may, as a result of dealings, become our shareholders (together, the “Permitted ExistingShareholders”) would have no influence over the Global Offering and would not be inpossession of any non-public inside information and would therefore effectively be in the sameposition as any of the public investors.

As of June 30, 2021, other than SINA Corporation and Ali WB, we had no shareholder who wasnot a director and held 10% or more of our issued share capital.

We have applied for, and the Hong Kong Stock Exchange has granted, a waiver from strictcompliance with the requirements of Rule 10.04 of and Paragraph 5(2) of Appendix 6 to theHong Kong Listing Rules in respect of the restriction on Permitted Existing Shareholders tosubscribe for or purchase Shares in the Global Offering, subject to the following conditions:

(a) each Permitted Existing Shareholder is interested in less than 5% of our issued sharecapital immediately before the Listing;

(b) each Permitted Existing Shareholder is neither our director nor member of our seniormanagement;

WAIVERS AND EXEMPTIONS

– 160 –

(c) the Permitted Existing Shareholders do not have the power to appoint directors or anyother special rights in us;

(d) the Permitted Existing Shareholders do not have influence over the offering process andwill be treated the same as other applicants and placees in the Global Offering;

(e) the Permitted Existing Shareholders and their close associates will be subject to the samebook-building and allocation process as other investors in the Global Offering; and

(f) no preferential treatment will be given to the Permitted Existing Shareholders and theirclose associates in the allocation process by virtue of their relationship with ourCompany. To the best of our knowledge and belief, each of our Company, the JointSponsors and the Joint Representatives (based on (i) its discussions with our Companyand the Joint Representatives and (ii) the confirmations in the form as set out in ExhibitA to be submitted to the Stock Exchange by our Company and the Joint Representatives)confirms to the Hong Kong Stock Exchange in writing that, to the best of its knowledgeand belief, it has no reason to believe that any preferential treatment has been, or will be,given to the Permitted Existing Shareholders or their close associates as a placee in theInternational Offering by virtue of their relationship with our Company.

We expect to satisfy all the conditions set out in paragraph 4.20 of Guidance LetterHKEX-GL85-16 so that no actual or perceived preference will be given to the PermittedExisting Shareholders due to their existing shareholdings in our Company.

Allocation to the Permitted Existing Shareholders and/or their close associates will not bedisclosed in our allotment results announcement (other than to the extent that such PermittedExisting Shareholders or close associates subscribe for shares as cornerstone investors) unlesssuch permitted existing shareholders are interested in 5% or more of our issued share capitalafter the Global Offering as disclosed in any public filings with the SEC, as it would be undulyburdensome for us to disclose such information given that there is no requirement to discloseinterests in equity securities under the U.S. Exchange Act unless the beneficial ownership ofsuch person (including directors and officers of the company concerned) reaches more than 5%of equity securities registered under section 12 of the U.S. Exchange Act.

THREE YEAR RESTRICTIONS TO SPIN-OFFS

Rule 19C.11 of the Hong Kong Listing Rules provides that, among other things, paragraphs 1to 3(b) and 3(d) to 5 of Practice Note 15 to the Hong Kong Listing Rules do not apply to aQualifying Issuer that has, or is seeking, a secondary listing on the Hong Kong StockExchange. This exception is limited to circumstances where the spun-off assets or businessesare not to be listed on the Hong Kong Stock Exchange’s markets and the approval ofshareholders of the Parent is not required.

Paragraph 3(b) of Practice Note 15 to the Hong Kong Listing Rules provides that the ListingCommittee would not normally consider a spin-off application within three years of the dateof listing of the Parent, because the original listing of the Parent will have been approved onthe basis of the Parent’s portfolio of businesses at the time of listing, and the expectation ofinvestors at that time would have been that the Parent would continue to develop thosebusinesses.

WAIVERS AND EXEMPTIONS

– 161 –

Our Company, from time to time, consider different opportunities to bring value to ourShareholders, including spinning off any of our business subsidiaries when they have reacheda desirable level of maturity. The exact timing of any potential spin-off would depend on thedevelopment of each of the business subsidiaries and market conditions. In some cases, it ispossible that a spin-off within three years of the Listing may be appropriate. As of the LatestPracticable Date, we have not identified any target for a potential spin-off and as a result wedo not have any information relating to the identity of any spin-off target or any other detailsof any spin-off; and accordingly, there is no material omission of any information relating toany possible spin-off in this document. Any potential spin-offs by our Company will be subjectto compliance with all applicable requirements under the Hong Kong Listing Rules, includingPractice Note 15 to the Hong Kong Listing Rules, unless otherwise waived by the Hong KongStock Exchange.

No shareholders’ approval with respect to a potential spin-off will be required under ourArticles under applicable U.S. regulations and Nasdaq listing rules. Further, as we are aGrandfathered Greater China Issuer and therefore exempt from the requirements under Chapter14 of the Hong Kong Listing Rules pursuant to Rule 19C.11 of the Hong Kong Listing Rules,no shareholders’ approval will be required under the Hong Kong Listing Rules as well.

The effect of a spin-off to our Shareholders should be the same regardless of whether or notthe businesses to be potentially spun-off are to be listed on the Hong Kong Stock Exchange(save with respect to any preferential rights to subscribe for shares that are commonly providedin spin-offs on the Hong Kong Stock Exchange). Given the fact that certain spin-offs byGrandfathered Greater China Issuers are allowed within three years after their listing in HongKong pursuant to Rule 19C.11 of the Hong Kong Listing Rules, we believe that the three-yearrestriction on spin-offs on the Hong Kong Stock Exchange should also be waived and shall notapply to a potential spin-off by our Company.

Our Company and any subsidiary in respect of which a potential spin-off is contemplated willbe subject to compliance with all other applicable requirements under the Hong Kong ListingRules, including the remaining requirements of Practice Note 15 to the Hong Kong ListingRules and the applicable listing eligibility requirements under the Hong Kong Listing Rules,unless otherwise waived by the Hong Kong Stock Exchange.

Under U.S. securities laws and Nasdaq rules, we are not subject to any restrictions similar tothe three-year restriction under paragraph 3(b) of Practice Note 15 to the Hong Kong ListingRules in relation to the spin-offs of its business subsidiaries, nor is there any requirement forus to disclose any details of its potential spin-off entities when such information is notavailable because of the absence of any concrete spin-off plan.

Our directors owe fiduciary duties to our Company, including the duty to act in what theyconsider in good faith to be in the best interests of our Company; as such they will only pursuea potential spin-off if there are clear commercial benefits both to our Company and the entityto be spun off; and the directors will not direct our Company to conduct any spin-off if theybelieve it will have an adverse impact on the interests of our Shareholders.

We have applied for, and the Hong Kong Stock Exchange has granted, a waiver from strictcompliance with the requirements in paragraph 3(b) of Practice Note 15 to the Hong KongListing Rules, on the following grounds:

(i) we will not within three years after the Listing spin off any of our business subsidiariesuntil we confirm with the Hong Kong Stock Exchange with basis that the potentialspin-off would not render our Company, excluding any subsidiary to be spun off, failing

to meet the eligibility requirements under Rules 19C.02 and 19C.05 of the Hong KongListing Rules based on the financial information of any subsidiary to be spun off at thetime of the Listing, and where more than one subsidiary is to be spun off, the assessmentwill be made on a cumulative basis;

(ii) we will disclose in this document our intention relating to any potential spin-off withinthree years after the Listing and the risks relating to the uncertainty and timing of anypotential spin-offs. See “Risk Factors — Risks Relating to Our Business — Divestituresof businesses and assets may have a material and adverse effect on our business andfinancial condition”;

(iii) any potential spin-offs by our Company will be subject to the requirements of PracticeNote 15 to the Hong Kong Listing Rules (other than paragraph 3(b) thereof), includingthat each of our Company and any business subsidiary to be spun off will satisfy theapplicable listing eligibility requirements on a standalone basis; and

(iv) disclosure of this waiver in this document.

NOT A PUBLIC COMPANY IN HONG KONG UNDER THE TAKEOVERS CODE

Section 4.1 of the Introduction to the Takeovers Code provides that the Takeovers Code appliesto “public companies in Hong Kong.” The note to Section 4.2 of the Introduction to theTakeovers Code provides that a Grandfathered Greater China Issuer within the meaning of Rule19C.01 of the Hong Kong Listing Rules with a secondary listing on the Hong Kong StockExchange will not normally be regarded as a public company in Hong Kong under Section 4.2of the Introduction to the Takeovers Code. Where the bulk of trading in the shares of aGrandfathered Greater China Issuer migrates to Hong Kong such that it would be treated ashaving a dual-primary listing in Hong Kong pursuant to Rule 19C.13 of the Listing Rules, theTakeovers Code will apply to it.

We have applied for, and the SFC has granted, a ruling that our Company is not a “publiccompany in Hong Kong” for the purposes of the Takeovers Code.

DISCLOSURE OF INTERESTS UNDER PART XV OF THE SFO

Part XV of the SFO imposes duties of disclosure of interests in the securities of companieswhose securities are listed on the Hong Kong Stock Exchange on the relevant company, itssubstantial shareholders and its directors/chief executives. Under the U.S. Exchange Act, anyperson (including directors and officers of the company concerned) who acquires beneficialownership, as determined in accordance with the rules and regulations of the SEC and whichincludes the power to direct the voting or the disposition of the securities, of more than 5% ofa class of equity securities registered under Section 12 of the U.S. Exchange Act must filebeneficial owner reports with the SEC, and such person must promptly report any materialchange in the information provided (including any acquisition or disposition of 1% or more ofthe class of equity securities concerned), unless exceptions apply. Therefore, compliance withPart XV of the SFO would subject our corporate insiders to a second level of reporting, whichwould be unduly burdensome to them, would result in additional costs and would not bemeaningful, since the statutory disclosure of interest obligations under the U.S. Exchange Actthat apply to us and our corporate insiders would provide our investors with sufficientinformation relating to the shareholding interests of our significant shareholders.

We have applied for, and the SFC has granted, a partial exemption from Part XV of the SFO(other than Divisions 5, 11 and 12) on the following conditions:

WAIVERS AND EXEMPTIONS

– 163 –

(a) the bulk of trading in the Shares is not considered to have migrated to Hong Kong on apermanent basis in accordance with Rule 19C.13 of the Hong Kong Listing Rules;

(b) the disclosures of interest filed in the SEC are also filed with the Hong Kong StockExchange as soon as practicable, which will then publish such disclosure in the samemanner as disclosures made under Part XV of the SFO; and

(c) we will advise the SFC if there is any material change to any of the information whichhas been provided to the SFC, including any significant changes to the disclosurerequirements in the U.S. and any significant changes in the volume of our worldwideshare turnover that takes place on the Hong Kong Stock Exchange.

HISTORY AND CORPORATE STRUCTURE

Minority Investment in Weimeng

In April 2020, WangTouTongDa (Beijing) Technology Co., Ltd., an entity affiliated withZhongWangTou (Beijing) Technology Co., Ltd., made an investment of RMB10.7 million inWeimeng for 1% of Weimeng’s enlarged registered capital. Such third party minority stakeholder is entitled to customary economic rights in proportion to its equity ownership, andcertain minority shareholder rights such as the right to appoint a director to Weimeng’sthree-member board of directors, and veto rights over certain matters related to contentdecision, and certain future financings of Weimeng.

The third party minority stake holder is not a party to the contractual arrangements that arecurrently in effect among Weimeng, Weibo Technology and Weimeng’s other shareholders. Assuch, despite the fact that we are still able to enjoy economic benefits and exercise effectivecontrol over Weimeng and its subsidiaries, we are not able to purchase or have the third partyminority stake holder pledge its 1% equity interests in Weimeng in the same manner as agreedunder existing contractual arrangements, nor are we granted the authorization of voting rightsover these 1% equity interests. We believe Weibo Technology, our wholly-owned PRCsubsidiary, still controls and is the primary beneficiary of Weimeng as it continues to have acontrolling financial interest in Weimeng pursuant to ASC 810-10-25-38A after the issuance ofsuch 1% equity interests.

Although we have been advised by our PRC counsel, TransAsia Lawyers, that ourarrangements with Weimeng are not in conflict with current PRC laws and regulations, wecannot assure you that we will not be required to restructure our organization and operationsin China to comply with the changing and new PRC laws and regulations. Restructuring of ouroperations may result in disruption to our business. If PRC tax authorities were to determinethat our VIE structure was not done on an arm’s-length basis and therefore constitutesfavorable transfer pricing, they could request Weimeng to adjust its taxable income upward forPRC tax purposes. Such a pricing adjustment may not reduce the tax expenses of WeiboTechnology but could adversely affect us by increasing Weimeng’s tax expenses, which couldsubject Weimeng to late payment fees and other penalties for tax underpayment and/or couldresult in the loss of tax benefits available to Weibo Technology in China. Any of these measuresmay result in adverse tax consequences to us and adversely affect our results of operations.

Our PRC Legal Adviser is of the opinion that:

(a) our current ownership structure, the ownership structure of our PRC subsidiaries and ourVIEs, and the contractual arrangements among our PRC subsidiaries, the VIEs and theirrespective shareholders are in compliance with existing PRC laws, rules and regulations.

(c) each of the contractual arrangements entered into among our PRC subsidiaries, the VIEsand their respective shareholders governed by PRC laws and regulations is not void underthe Civil Code of the PRC.

See “Risk Factors — Risks Relating to Our Corporate Structure”.

It is uncertain whether any new PRC laws relating tocontractual arrangements will be adopted, what the Laws would provide. If we or any of theVIEs is found to be in violation of existing or future PRC laws, or fail to obtain or maintainany of the required permits or approvals, the relevant PRC regulatory authority would havebroad discretion to take action in dealing with the violation or failure, in which case we couldbe subject to severe penalties, including being prohibited from continuing our operations orunwinding the contractual arrangements.

MAJOR TRENDS FOR SOCIAL MEDIA PLATFORMS IN CHINA

The major trends for the social media platforms in China include:

Diversification of content formats

Content made available in different formats is suitable for meeting users’ different preferencesand consumption needs. For example, text is more efficient when distributing breaking newsand presenting thought-provoking content. At the same time, people increasingly enjoyconsuming content in richer and more interesting formats, such as video, which can capturemoments in a real-time, rich multi-sensory and condensed short-form manner. Therefore, thecontinuous diversification of content formats, including text, picture, video and live streaming,is expected to lead to an increase in both content generation and content consumption.

INDUSTRY OVERVIEW

– 184 –

KOL gaining more influence

Top content creators may often become the authoritative figures on certain topics or areas ofinterests and the opinion leaders among their followers, and therefore creating a considerableamount of influence on their followers. The influence on followers presents significantcommercial potential, which attracts more users to become influencers or KOLs bycontinuously creating high-quality content and engaging with followers. The resources andtools provided by social media platforms are also catalyzing this trend by making it easier fortalented content creators to stand out.

More users from the younger generation

At the same time, asyounger users are relatively more likely to access social media on their mobile devices atgreater frequencies, and often do so over fragmented periods of time, condensed content andshort format of content are therefore expected to gain more popularity among these users.

Prevalence of social e-commerce

Social e-commerce emerges as an important segment of China’s social media platforms, whichreflects a trend for purchasers to share experiences with a broader audience online, as well asa growing appetite for authentic real-world information shared by others virtually.

INDUSTRY OVERVIEW

– 187 –

Comprehensive coverage of content formats and categories

Social media platforms with comprehensive content categories and formats, and vibrantcontent ecosystems are better positioned to address the evolving needs of users with differentbackgrounds and interests. A diversified mix of content formats can better match users’preferences in different scenarios. A wider coverage of content categories can attract users witha variety of interests and can therefore increase the scale of the active user base. An engagingcontent ecosystem, powered by comprehensive content formats and categories, is vital for thesuccess of social media platforms to build thriving social scenes bolstered by robustcommunication and the frequent sharing of high-quality content by users.

Sustainable supply of rich, interesting and comprehensive content

A sustainable supply of content will attract users, which is important to the continued successof social media platforms.

COMPETITIVE LANDSCAPE FOR SOCIAL PLATFORMS

Driven by the increasing popularity of social platforms, the penetration rate for the socialplatforms, measured by the ratio of overall social platform users to all mobile users, hasalready come to hover near the 100% mark in 2020.

MAJOR CHALLENGES FACED BY THE SOCIAL PLATFORMS AND SOCIAL MEDIAPLATFORMS IN CHINA

Competition for user acquisition and user engagement

Driven by the increasing popularity of social platforms, the penetration rate for the socialplatforms, measured by the ratio of overall social platform users to all mobile users, hasalready come to hover near the 100% mark in 2020. Currently, almost every mobile user usessome forms of social platform to stay current or connect with others. As a result, new useracquisition has been one of the key challenges that each of the social platforms faces andaccordingly, established social platforms with a large user base may experience weak growthin user base. In addition to expanding user base, social platforms mainly leverage the networkeffect to build their competitive moat. Therefore, social platforms and social media platformsneed to devote significant resources to retain existing users and content creators, and improvethe quality and diversity of content ecosystems, such as content formats and categories, inorder to continuously attract and engage users and boost their time spent. See “Risk Factors –Risks Relating to Our Business – If we fail to grow our active user base, or if user engagementon our platform declines, our business, financial condition and operating results may bematerially and adversely affected.,” “Risk Factors – Risks Relating to Our Business – If ourusers and platform partners do not continue to contribute content or their contributions are notvaluable to other users, we may experience a decline in user traffic and user engagement.,” and“Risk Factors – Risks Relating to Our Business – If we are unable to compete effectively foruser traffic or user engagement, our business and operating results may be materially andadversely affected.”

In recent years, social platforms are exploring and developing new monetization opportunitiessuch as KOL marketing, live streaming e-commerce and other types of social e-commerce.However, as their business models evolve, social platforms may influence consumers’online-shopping habits since certain users may shift to social platforms from other types ofe-commerce platforms. As a result, such exploration of new monetization models may subjectsocial platforms to competition from other types of online businesses or industries.

Technology

Social media platforms that can constantly provide innovative and effective advertisingtechnologies and solutions are more likely to be favored by advertisers. More innovativeadvertising and marketing products and services are expected to emerge in the future,especially in the field of content marketing or KOL marketing. Therefore, social mediaplatforms need to continuously enhance their technology capabilities to capitalize on the latesttrends to compete in the market for online social media. Furthermore, technology infrastructureis critical to providing users, customers and platform partners access to social media platform,particularly during major events when activities on the platforms increase substantially. Asocial media platform must continue to upgrade and expand its technology infrastructure tokeep pace with the growth of its business and to ensure that technical difficulties do not detractfrom user experience or deter new users, customers or platform partners from accessing itsplatform. See “Risk Factors – Risks Relating to Our Business – We generate a substantialmajority of our revenues from online advertising and marketing services. If we fail to generatesustainable revenue and profit through our advertising and marketing services, our result ofoperations could be materially and adversely affected.,” “Risk Factors – Risks Relating to OurBusiness – User growth and engagement depend upon effective interoperation with operatingsystems, networks, devices, web browsers and standards that we do not control.,” and “RiskFactors – Risks Relating to Our Business – Our business and operating results may be harmedby service disruptions, or by our failure to timely and effectively scale and adapt our existingtechnology and infrastructure.”

Regulations

The PRC government has, in recent years, heightened its oversight over various aspects of theoperation of social platforms and social media platforms as well as the provision of onlinecontent in China in certain areas, including but not limited to, cybersecurity, protection ofpersonal information, review of illegal and inappropriate content, and real-name authenticationon live broadcasting businesses and online mobile games and etc. Internet information serviceproviders are required to ensure that the large amount of content available on their platformsand the operation and services fully comply with relevant PRC laws and regulations. Socialmedia platforms are also required to monitor the advertising content shown on their platformsto ensure that such content is true and accurate and in compliance with relevant PRC laws andregulations. Due to these intensified laws and regulations, social platforms may be severelyaffected in the short term since some advertisers may no longer be able to conduct marketingactivities or display advertisements on social platforms. As a result, social platforms may needto invest additional resources to continuously develop new clients. See “Risk Factors – RisksRelating to Our Business – Advertisements shown on our platform may subject us to penaltiesand other administrative actions.,” “Risk Factors – Risks Relating to Our Business – Privacyconcerns relating to our products and services and the use of user information could damageour reputation, deter current and potential users and customers from using Weibo andnegatively impact our business.,” and “Risk Factors – Risks Relating to Our Business – Usermisconduct and inappropriate content may adversely impact our brand image, business andresults of operations, and we may be held liable for information or content displayed on,retrieved from or linked to our app or website or distributed to our users.”

PRODUCTS AND SERVICES

Our product categories include those for users, advertising and marketing customers andplatform partners.

Products for Users

Our product development approach is centered on building simple and useful tools to enableour users to access Weibo to discover, create, and distribute content and interact with others onour platform in real time. We employ a “mobile first” philosophy and have designed ourplatform around the capabilities of mobile devices. We introduced the first generation of theWeibo mobile app in the first quarter of 2010.

themselves on our platform by following, liking, reposting, adding comments, sending privatemessages, and participating in topic discussions and group chats. In addition, we officiallylaunched a new product named Oasis in the fourth quarter of 2019, an interest-based socialcommunity product for users to share lifestyle related content in the form of photos and shortvideos.

Starting from a social media platform primarily focusing on text and photo, Weibo has beenrolling out new formats, such as video and live streaming, to meet users’ evolving demands.With its continuous efforts in capitalizing on new content formats, Weibo now offers the mostcomprehensive content format and coverage of content categories and content creators amongsocial platforms in China, according to the CIC Report. Weibo plans to leverage its socialattributes and extensive content coverage to attract more users to use Weibo for video postingand consumption. To further improve its competitiveness in video offering, Weibo will promoteits Video Account program among its users and accelerate the videolization for Weibo’s contentcreators. Weibo believes the popularity of the emerging content formats, such as video and livestreaming, will further diversify and enhance its content offerings, which will in turn attractmore users, forming a thriving self-reinforcing content ecosystem.

Weibo serves a wide range of users including ordinary people, celebrities, KOLs, and otherpublic figures or influencers, as well as media outlets, businesses, government agencies,charities, and other organizations. Weibo has collaborated with industry leading multi-channelnetworks (MCNs) to provide high-quality content that spans across 46 content verticals in June2021.

Discovery. We offer the following products to help users discover content on our platform:

• Information Feed. We organize and present users with information feed in different forms.Among all our offerings, the two most important and most frequently browsed feeds arerelationship-based information feed (follow model) and interest-based information feed,both of which reside on users’ home page.

Each user’s relationship-based information feed displays a flow of feeds posted by thatuser and other users who he or she has opted to follow. Since Weibo allows users to followother users without establishing a reciprocal relationship, users are able to personalizewho they follow based on their interests. In other words, users can as easily followcelebrities and strangers as they follow friends and acquaintances. To improve userexperience, the relationship-based information feed has evolved from a chronologicaltimeline to one with multiple dimensions, including content relevancy, content quality,user interest, user engagement, user relationships, etc. Users can also customize theirinformation feed by classifying followed accounts into different groups, e.g. friends,co-workers, celebrities, finance, sports and view feeds from each group separately.

Interest-based information feeds are timelines of feeds recommended by Weibo based ondifferent interest-based themes. The hot information feed is an example of an interested-based information feed that we present on users’ homepages to recommend feeds onrecent popular topics, breaking news and feeds generated through user’s individualinterest. We also organize other interest-based information feeds on various themes forusers to further explore the topics in which they are interested. For example, the videoinformation feed, which is a timeline of recommended videos that appears after a userfinishes watching a short video; and the profile information feed, which can be found ona user’s individual page and shows all of the feeds shared by that user.

COMPETITION

We provide online social media services for users in China and the global Chinesecommunities. The social media industry is highly competitive and rapidly changing due to thequickly evolving market demand and user preferences. As a result, we face significantcompetition for user traffic, user engagement and advertising and marketing spending from awide array of existing and potential competitors who may launch new websites, apps, platformsor services at a relatively low cost. Many companies offer various content and services thatcompete with our offerings. With the growth rate of the overall size of the internet communityslowing down, the industry is evolving rapidly while witnessing rising competition for trafficand user time. See “Industry Overview — Competitive Landscapes for Social Platforms” and“Industry Overview — Competitive Landscape for Social Media Platforms”.

We are a media platform in nature, and major Chinese internet companies, such as Tencent andBytedance, that provide online media, including content aggregation and distribution services,compete directly with us for user traffic and user engagement, content, talent and marketingresources. In addition, as a social media platform featuring social networking services andproviding a rich variety of multimedia contents, we are subject to intense competition fromproviders of similar services, such as social networking platforms and multimedia contentplatforms with social features. We are subject to intense competition from providers of similarservices as well as potentially new types of online services. These services include (i)messengers and other social apps and sites, such as Weixin/WeChat, QQ Mobile, Qzone Mobileand Momo; (ii) news apps and sites, such as those operated by other major internet companies,including Tencent, Bytedance, Baidu, NetEase, Sohu and Phoenix News Media; (iii)multimedia apps (photo, video and live streaming, etc.), such as Douyin/TikTok, Kuaishou,Bilibili, iQiyi, Tencent Video, Youku, Xigua Video, Red (Xiaohongshu), Momo and JOYY.

For value-added services, we offer membership services, live streaming tools, game servicesand social commerce solutions to users that enable them to conduct related activities on ourplatform. Consequently, our value-added service offerings compete with platforms whichprovide similar services to users. In addition to direct competition, we face indirectcompetition from companies that sponsor or maintain high traffic volume websites or providean initial point of entry for internet users, including but not limited to providers of searchservices, web browsers and navigation pages.

We also face significant competition for advertising and marketing spending. A substantialmajority of our revenues is generated from the sale of advertising and marketing services. Wecompete against online and mobile businesses that offer such services, including but notlimited to online media platforms, social media and social networking platforms andmultimedia content platforms. We also compete with internet companies that offer online-to-offline, purchase solutions and other performance-based advertising services and digital mediatailored to vertical industries, such as automobile, IT and travel. We also compete againsttraditional media outlets, such as television, radio and print, for advertising and marketingspending.

Some of our larger competitors have substantially broader product or service offerings andleverage their relationships based on other products or services to gain a larger share ofadvertising and marketing budgets. We believe that our ability to compete effectively foradvertising and marketing spending depends upon many factors, including the size,composition and engagement of our user base, our advertisement targeting capabilities, marketacceptance of our advertising and marketing services, our marketing and selling efforts, thereturn our customers receive from our advertising and marketing services and the strength andreputation of our brands. See “Risk Factors — Risks Relating to Our Business — If we areunable to compete effectively for advertising and marketing spending, our business andoperating results may be materially and adversely affected.”

Video Platform. Our video platform supports media content in multiple formats. We haveupgraded our video encoder, making it possible to provide quality visual effects even when endusers’ bandwidths are limited. We invented a video orchestration engine, which hassignificantly increased the efficiency to process videos and the speed for users to uploadvideos. We utilize machine learning technologies to semantically understand videos uploadedto our platform, whereby we extract texts, basic features from videos to generate content labels,interest-based themes and video fingerprint information. We use these information toaccelerate content review of the videos and distribution of the videos on our platform.

Live Streaming System. We have developed a smart dispatch system that links push streamingwith node load balancing and optimal path finding technologies, which adjusts video caches toadapt to different networks and ensures video quality and stability in live streaming.

We maintain our own sales operations team. We transact business directly with key accountcustomers or through third-party advertising agencies and with SMEs primarily through ourdistribution network.

Due to the expertise required to carry out an effective online marketing campaign, key accountsusually hire advertising agencies to handle their internet brand campaigns. These advertisingagencies provide a broad spectrum of internet marketing and advertising services. Our salesteam leverages Weibo’s unique position and advantages in social marketing to assist keyaccount customers or their advertising agencies throughout their advertising campaign cycle,from designing advertisement campaigns and crafting advertisements in different formats toexecuting social marketing campaigns and providing analytical tracking.

Our distribution network for SME customers includes local distributors throughout China. Ourdistributors provide numerous services, including identifying customers, collecting payments,assisting customers in setting up their accounts with us, and engaging in other marketing andeducational services aimed at acquiring customers. We have relied on distributors for severalreasons. Our SME customer base in China is geographically diverse and fragmented, locatedin different regions in China. Moreover, SMEs are generally less experienced with onlineadvertising and marketing as compared to large companies and, therefore, benefit from thesupport provided by distributors. Distributors serve as an efficient channel for us to reach SMEcustomers throughout China and collect payments from them. We require distributors to staffdedicated customer service representatives for our SME customers. We provide periodictraining programs to our distributors to maintain the service quality of our distributors andstrengthen our relationships with them. In addition, we also offer marketing services throughour self-service platform on Weibo.

SINA acts as our agent in servicing our advertising and marketing clients. We have signed anagreement with SINA relating to these sales and marketing services. See “Related PartyTransactions — Our Relationship with SINA — (iv) Sales and Marketing Services Agreement.”We will continue to offer integrated solutions to customers with both SINA’s and ouradvertising and marketing solutions. We believe that our advertising and marketing solutionsare complementary to SINA’s.

We believe that our position as a leading social media platform in China has given uswidespread name recognition. We focus on continually improving the quality of our productsand services to strengthen our brand, as we believe satisfied users and customers are morelikely to recommend our products and services to others. While word of mouth has helped us,we also make selective use of advertising, promotions and special events to promote Weiboawareness and usage.

ENVIRONMENTAL, SOCIAL AND GOVERNANCE

Weibo is committed to living up to its social responsibilities and to facilitate meaningful publicaffairs dialogue. Media outlets use Weibo as a source of information and a distribution channelfor their headline news. Government agencies and officials use Weibo as an important officialcommunication channel for disseminating timely information and gauging public opinion toimprove public services. Individuals and charities use Weibo to make the world a better placeby launching charitable projects, seeking donations and volunteers and leveraging thecelebrities and organizations on Weibo to boost their social influence. For example, when theCOVID-19 pandemic unfolded across China in 2020, Weibo released a series of measures topromote public conversations and to help people find reliable and useful information. Inaddition, we launched Weibo Charity as early as 2012 to allow users to initiate charity projectsby posting messages on our platform. For detailed discussions, see “Business — OurCommitment to a Better Society.”

We commit to actively embracing different identities and individuals and to promote the valueof an inclusive and diverse culture with gender equality, which we believe attracts the besttalent. We adopted gender equality policy in making decisions over recruitment, training,promotion, salary, benefits and other human resources management activities. Adhering to ourequal employment and development principle, our human resources decisions shall be based oneach employee’s work performance, motivation, quality and specialty, regardless of gender,and in compliance with relevant rules and regulations. We continuously analyze and monitororganizational and diversity issues, including the gender and diversity composition of humanresources at various levels. Women hold various leader roles in our company, including Ms.Hong Du, our director, and Ms. Fei Cao, our chief financial officer. We will continue to worktowards enhancing the gender diversity of our Board, including, within three years after theListing, identify and recommend at least one female candidate to our Board for itsconsideration on appointment of a director, with the goal to achieve a higher percentage offemale board representatives, subject to our Directors (i) being satisfied with the competenceand experience of the relevant candidates after a holistic review process based on reasonablecriteria; and (ii) fulfilling their fiduciary duties to act in the best interest of our company andthe shareholders as a whole when deliberating on the appointment. We target to maintain aculture of inclusion and diversity through activities such as providing trainings over gender andinclusion, prevention of sexual harassment, and protection from sexual exploitation and abuse.

We are committed to carbon mitigation measures and will continue to explore ways to furtherimprove energy efficiency. We ask our employees to be mindful of the environment whenconsuming office supplies. Furthermore, some of the content offered on Weibo platform isdedicated to the environmental protection topics. Leveraging the various forms of content andtools we offer to content creators, environmentalists are well equipped to create and sharecontent on Weibo platform centered on environmental issues, which raises environmentalprotection awareness among the viewers. Our business is generally subject to relevant PRCnational and local environmental laws and regulations. However, our operations do not produceor discharge any industrial waste which is hazardous to the environment. As confirmed by ourPRC Legal Adviser, we are not required to obtain any approvals or certificates that areapplicable to environmental laws and regulations in the PRC.

We have formulated and implemented various workplace safety policies and procedures toensure that our employees have a safe working environment. During the Track Record Period,none of our employees were involved in any major accidents in their workplaces.

INTELLECTUAL PROPERTY

We rely on a combination of patent, copyright, trademark and trade secret laws and restrictionson disclosure to protect our intellectual property rights. As of June 30, 2021, we have registered193 patents and applied for an additional 218 patents with the PRC State Intellectual PropertyOffice. As of June 30, 2021, we have registered 302 software copyrights with the PRC NationalCopyright Administration. We have also registered domain names, including weibo.com,weibo.cn and weibo.com.cn. We have obtained an exclusive, perpetual, worldwide androyalty-free license from SINA to use its “ ” “ ” and “ ” trademarks.

We have implemented procedures to reduce the likelihood that content published on Weibomight be used without proper licenses or third-party consents. For example, we request usersto agree to the terms and conditions set forth in the user agreement of our platform, includingagreeing not to infringe the intellectual property rights of others. We leverage our technologyto monitor and protect original content on our platform. For example, we have launched aself-protection function for video content creators, and the fingerprint trails of their videos willbe extracted and saved in our system. Our system will compare against the fingerprint trailsextracted from the newly uploaded video by third parties, then send to our screening team forsecond-level manual review. We will replace the infringing content with the link to the originalcontent. Despite our efforts to protect our proprietary rights, unauthorized parties may attemptto copy or otherwise obtain and use our technology. Monitoring unauthorized use of ourtechnology is difficult and costly, and we cannot be certain that the steps we have taken willprevent misappropriation of our technology, particularly in foreign countries where the lawsmay not protect our proprietary rights as fully as in the United States. From time to time, wemay have to resort to litigation to enforce or defend our intellectual property rights, whichcould result in substantial costs and diversion of our resources.

In addition, third parties may initiate litigation against us alleging infringement of theirproprietary rights or declaring their non-infringement of our intellectual property rights. In theevent of a successful claim of infringement and our failure or inability to developnon-infringing technology or license the infringed or similar technology on a timely basis, ourbusiness could be harmed. In addition, even if we are able to license the infringed or similartechnology, license fees could be substantial and may adversely affect our results of operations.

During the Track Record Period, there have been no intellectual property infringement claimswhich, individually or in the aggregate, in our opinion, would have a material and adverseeffect on our business, financial condition or results. See “Risk Factors — Risks Relating toOur Business — We may not be able to adequately protect our intellectual property, whichcould cause us to be less competitive” and “Risk Factors — Risks Relating to Our Business —We may be subject to intellectual property infringement claims or other allegations by thirdparties for information or content displayed on, retrieved from or linked to our platform, ordistributed to our users, which may materially and adversely affect our business, financialcondition and prospects.”

SEASONALITY

Weibo has experienced seasonality in its online advertising business. Historically, advertisingspending tends to be the lowest in the first quarter of each calendar year due to long holidaysaround the Lunar New Year. Past performance may not be indicative of future trends, as the mixof advertising industry sectors, which may have different seasonality factors, may shift fromquarter to quarter.

CUSTOMERS AND SUPPLIERS

Our five largest suppliers, who are generally marketing or bandwidth services providers,accounted for less than 30% of our purchases for each of the years and periods over the TrackRecord Period. Our five largest customers accounted for less than 30% of our total net revenuesfor each of the years and periods over the Track Record Period. We mainly provided advertisingand marketing solutions over the Track Record Period to our major customers to promote theirbrands and conduct effective marketing activities.

Wecontinually review the implementation of our risk management and internal control policiesand procedures to enhance their effectiveness and sufficiency.

Financial reporting risk management

We have a set of accounting policies in place in connection with our financial reporting riskmanagement, such as financial reporting management policy and treasury management policy.Our finance department reviews our management accounts based on such policies. We alsoprovide regular training to our finance department employees to ensure that they understandour financial management and accounting policies and implement them in our daily operations.

Internal control risk management

We have designed and adopted strict internal procedures to ensure the compliance of ourbusiness operations with the relevant rules and regulations. Our internal control team worksclosely with our legal, finance and business departments to: (a) perform risk assessments andadvise risk management strategies; (b) improve business process efficiency and monitorinternal control effectiveness; and (c) promote risk awareness throughout our Company.

We employ technologies such as AI capture and key words detection to detect illegal orinappropriate content. Our review team is on 24/7 shifts to ensure sufficient manpower tomonitor content on our platform.

We have taken various measures in order to comply with PRC laws and regulations governingadvertisements. We have established a comprehensive system to review and monitor thecontent of advertisements, including a robust advertisement registration, review, and filingmanagement system. We request every advertising account to provide us with its businesslicense for our review before publishing advertisements. We will cross-check the documentscertifying the advertisement content provided by the advertising account against the actualadvertisements in accordance with PRC laws and regulations. We adopt a machine plus manualapproach to review the content of advertisements. We employ technologies such as AI captureand key words detection to detect illegal or inappropriate content in advertisements beforepublishing them online. We have established a special taskforce for content review ofadvertisements, which consist of qualification review team, content review team, qualitycontrol team and data system refinement team, among others. All of the team members arerequired to receive trainings and pass examinations prior to being on board, and also need topass regular tests afterwards. Our advertisement inspection team is on 24/7 shifts to inspect thecontent of advertisements through various channels such as designated advertisement reviewpublic account and email box. In the event that an advertisement is found to contain harmfulor illegal content, we will immediately delete such advertisement or freeze the publisher’saccount. We have developed a system to monitor the landing page of advertisements to furtherdetect and curb illegal marketing practices.

We have taken various measures in order to comply with PRC laws and regulations governinganti-monopoly and competitions. Based on the requirements under Anti-Monopoly Law (中華人民共和國反壟斷法), Anti-Monopoly Guidelines for the Internet Platform Economy Sector(《國務院反壟斷委員會關於平台經濟領域的反壟斷指南》), Anti-Monopoly ComplianceGuideline for Operators (《經營者反壟斷合規指南》) and other relevant rules and regulations,we have established a comprehensive system to internally review our investment andacquisitions, so as to assess their implications under PRC anti-monopoly laws and regulationsand the necessity to make filings with any competent PRC regulatory authorities. This systemincludes detailed procedures, methods, preparation and record keeping requirements,supervision policies and penalties in relation to the internal review and assessment. We havealso established a special task force to oversee our applications for investment and acquisitionsunder this internal review system, and to support and assist the subsidiaries within our groupfor the review and assessment over their investment and acquisitions.

Data and technology system risk management

Sufficient maintenance, storage and protection of user data and other related information iscritical to our business. We dedicate significant resources to developing and implementingprograms designed to protect user privacy, promote a safe environment and ensure the securityof user data.

We require our users to accept terms of services under which they agree to provide certainpersonal information to us, to have established information security systems protect userprivacy and to have such information filed with the MIIT or its local branch as required.

We have taken various steps in order to comply with applicable data security and dataprotection requirements. Specifically, we collect personal information and data from users onlywith their prior consent and make reasonable efforts to prevent the unauthorized use of userdata. We update our user privacy policy, Weibo Personal Information Protection Policy, on a

BUSINESS

– 217 –

regular basis in order to reflect any new data protection rules and policies. In our policy, wehave clearly set forth how we will collect, protect and store personal information that is beingcollected. For instance, we will collect a user’s profile name, email address and phone numberwhen this user registers an account on our platform. When a user logs into our platform througha third party platform, we will collect his or her profile picture, profile name and location, thepurposes of which is mainly to complete real-name identification on our platform.

In addition, we have implemented enhanced data security measures and technologies, adopteda data classification and grading system which offers various levels of data protection, strictlylimited internal access to user data on a need-to-know basis, and encrypted and desensitizeduser data whenever necessary. We have also appointed a team of dedicated data protectionprofessionals who are responsible for designing and monitoring data security management andemergency response. Data access attempts by any third party are subject to our formalevaluation and approval procedure based on the necessity and scope of the access attempts andappropriate consent from users. We typically provide third parties with anonymized andde-identified personal information and require such third parties to undertake equivalent dataprotection measures.

Although we and our PRC Legal Adviser believe that we have effective measures in place toensure compliance with applicable PRC laws and regulations relating to privacy and datacollection in all material respects, there are substantial uncertainties with respect to theinterpretation and implementation of these data security laws and regulations since datasecurity laws and regulations are relatively new. As such, we cannot assure you that our privacyand data protection measures are, and will be, always considered sufficient under applicablelaws and regulations. Weibo may need to adjust its business to comply with data securityrequirements from time to time. Weibo has made significant efforts to comply with existinglaws and regulations. Weibo will maintain active communication with the regulatoryauthorities and will rectify any problems as soon as possible, if any.

Human resources risk management

We provide regular and specialized training tailored to the needs of our employees in differentdepartments and compliance policies. We regularly organize internal training sessionsconducted by senior employees or outside consultants.

We believe that we maintain a good working relationship with our employees, and we have notexperienced any material labor disputes. None of our employees are represented by laborunions.

PROPERTIES

Our headquarters and our principal product development facilities are located in Beijing. As ofJune 30, 2021, we have leased approximately 25,000 square meters of office space mainly inBeijing, Shanghai and Tianjin. These leases have various expiration dates. In addition, SINAallocates rental expenses to us for some of its office space where SINA employees devote partof their time to providing services to us or where SINA shares certain office space (SINAPlaza) with us for our employees to use.

The servers that support our products and services are primarily maintained at ChinaTelecommunications Corporation, or China Telecom, China Unicom branches, Ali Cloud andHuawei Cloud services in cities across China, as well as servers located in Taipei, Santa Clara,California and Hong Kong. We share the use of domestic servers with SINA during the ordinarycourse of our business. Maintenance and repair are the responsibility of SINA employees forthe time being. See “Related Party Transactions — Our Relationship with SINA.”

As of the Latest Practicable Date, we have not registered most of our lease agreements withthe relevant government authorities. The failure to register the lease agreements for our leasedproperties will not affect the validity of these lease agreements, but the competent housingauthorities may order us to register the lease agreements in a prescribed period of time andimpose a fine ranging from RMB1,000 to RMB10,000 for each non-registered lease agreementif we fail to complete the registration within the prescribed timeframe. As at the LatestPracticable Date, we have not received any notification from any competent authority in thePRC in relation to the non-registration of lease agreements. For more details of the risks anduncertainties, see “Risk Factors — Risks Relating to Doing Business in the People’s Republicof China — We face certain risks relating to the real properties that we lease.”

INSURANCE

We consider our insurance coverage to be adequate as we have in place all the mandatoryinsurance policies required by Chinese laws and regulations and in accordance with thecommercial practices in our industry. Our employee-related insurance consists of pensioninsurance, unemployment insurance, maternity insurance, work-related injury insurance,medical insurance and housing funds, as required by Chinese laws and regulations. To complywith these laws and regulations, we have caused all of our full-time employees to enter intolabor contracts and provide our employees with the proper welfare and employment benefits.

We have limited business liability or disruption insurance coverage for our operations. Duringthe Track Record Period, we did not make any material insurance claims in relation to ourbusiness, see “Risk Factors — Risks Relating to Our Business — We have limited businessinsurance coverage.”

LEGAL PROCEEDINGS AND COMPLIANCE

From time to time, we have been involved in litigation or other disputes regarding, among otherthings, copyright and trademark infringement, defamation, unfair competition and labordisputes. For example, our company has been named as a defendant in two civil actions filed

BUSINESS

– 220 –

in Texas and in California by the same individual plaintiff, alleging that her rights under theFourteenth Amendment to the United States Constitution were violated when our companyallegedly shut down her Weibo accounts without good cause. Both lawsuits have beendismissed.

For many of these legal proceedings, we are currently unable to estimate the reasonablypossible loss or a range of reasonably possible loss as the proceedings are in the early stages,or there is a lack of clear or consistent interpretation of laws specific to the industry-specificcomplaints among different jurisdictions. As a result, there is considerable uncertaintyregarding the timing or ultimate resolution of such proceedings, which includes eventual loss,fine, penalty or business impact, if any, and therefore, an estimate for the reasonably possibleloss or a range of reasonably possible loss cannot be made. With respect to the limited numberof proceedings for which we are able to estimate the reasonably possible loss or the range ofreasonably possible loss, such estimates are immaterial. We believe that such proceedings,individually and in the aggregate, when finally resolved, are not reasonably likely to have amaterial and adverse effect on our results of operations, financial position and cash flows.

During the Track Record Period, we paid an aggregate of approximately RMB14.2 million toclaimants of legal proceedings. As of the Latest Practicable Date, there were five materialoutstanding claims, which represent claims in excess of RMB10 million, with an aggregateclaim amount of approximately RMB146.7 million. Among these five outstanding claims,Weibo was named as defendant in only one claim for an amount of approximately RMB15.1million.

The Administrative Provisions on Online Publishing Services requires an internet publishingservice provider to obtain an internet publishing permit. One of our PRC subsidiaries jointlyoperated mobile games developed by third parties during the Track Record Period. The mobilegames provided at our platform have been published through third party licensed electronicpublishing entities and registered with the NPPA as electronic publications. However, theprovision of online games by us may be deemed as a type of online publishing services. Dueto the failure to obtain this permit, we may be subject to various penalties, such as confiscationof the net revenues that were generated through online games, the imposition of fines, therevocation of our business and operating licenses and the discontinuation or restriction of ouroperations of online games. In May 2021, our PRC Legal Adviser conducted telephoneinterviews with officers in the relevant departments of the NPPA (through the NPPA’s officialenquiry line accessed through, and published on, its official website), being the competent

persons of the competent regulatory authority in relation to the internet publishing permit. TheNPPA confirmed that it would not order operators without an internet publishing permit to shutdown their websites or Apps, on the condition that the content of their publications complywith the requirements of laws and regulations. Revenues generated from game-related servicesaccounted for less than 5% of our total net revenues in 2018, 2019 and 2020, except thatrevenues generated from game-related services accounted for 5.1% of our total net revenues inthe six months ended June 30, 2021.

The Rules for the Administration of Internet Audio and Video Program Services requirecompanies providing audio/video programs to the public via the internet and the service ofuploading and spreading audio/video programs to obtain the audio/video program transmissionrelated qualifications. Weimeng, one of our PRC subsidiaries, operates live streaming businessand provides users with the services of uploading audio/video programs. Weimeng is notqualified to obtain the internet audio/video program transmission license under the currentlegal regime as it is not a wholly state-owned or state-controlled company and it was notoperating prior to the issuance of the Rules for the Administration of Internet Audio and VideoProgram Services, commonly known as Circular 56. However, in 2019, we have registered withthe National Internet Audio-Visual Platforms Information Management System, through whichour operations of audio/video programs are supervised and guided by the National Radio andTelevision Administration and its local branches. This registration was valid until May 1, 2021and is currently under the annual renewal process. In May 2021, our PRC Legal Adviserconducted telephone interviews with officers in the relevant departments of Beijing MunicipalRadio and Television Bureau and National Radio and Television Administration (through theirofficial enquiry lines accessed through, and published on, their official websites), each beinga competent person in the competent regulatory authorities in relation to the internetaudio/video program transmission license. The Beijing Municipal Radio and Television Bureauand National Radio and Television Administration each confirmed that if the filings in NationalInternet Audio-Visual Platforms Information Management System has been completed, and aslong as the platform follows the guidance from the regulatory authorities, such platform couldcontinue to provide audio/video program services without obtaining the audio/video programtransmission license. Based on the confirmation from the above competent authorities and asadvised by our PRC Legal Adviser, we may continue to provide internet audio-visual programservices as currently conducted, so long as our operations are in compliance with the operatingrequirements under the PRC laws and regulations governing audio-visual program services,proper filings with and review under National Internet Audio-Visual Platforms InformationManagement System and follow the guidance from the regulatory authorities. Due to the failureto obtain this license, we may be subject to various penalties, such as including removal of therelevant online publications, confiscation of illegal income, fines, and/or the closure of ourrelevant websites which could lead to severe disruption to our business operation. Our PRCLegal Adviser has advised us that, as long as we take immediate remedial actions if requiredby the regulatory authorities, the likelihood of us being subject to an order to suspend ourinternet audio-visual program services because of the above situation is low. Revenuesgenerated from live streaming accounted for less than 5% of our total net revenues during theTrack Record Period.

RECENT REGULATORY DEVELOPMENTS

On August 30, 2021, the NPPA issued the Notice on Further Strict Management to PreventMinors from Indulging in Online Games (《關於進一步嚴格管理切實防止未成年人沉迷網絡遊戲的通知》), which requires all online game operators to provide services to minors only onany Friday, Saturday, Sunday and statutory holidays from 8:00 p.m. to 9:00 p.m., i.e. for onehour, and not to provide online games in any form to users who have not registered or loggedin with their real names. In addition to the real-name registration system already in place, we

BUSINESS

– 223 –

have adjusted the systems in the games operated by us to comply with the requirements underthis notice. The revenue contributed by online games accounted for an insignificant portion ofour total revenue during the Track Record Period. The Company is of the view that this noticewill not have a material adverse impact on its business operation or financial results.

The Cyberspace Administration of China launched a “Fan Group Chaos Rectification” specialaction on June 15, 2021, followed by the issuance of the Notice on Further Strengthening theManagement of Chaos in Fan Groups (《關於進一步加強“飯圈”亂象治理的通知》) on August25, 2021. Both of the special action and notice are intended to rectify chaos in online fangroups for celebrities, specifically, in features such as celebrity rankings, hot topics, fancommunities, and fans interactive functions, so as to curb verbal abuse, stigmatization,instigation, confrontation, insults, slander, rumors, malicious marketing and the spread of otherharmful information. This notice requested, among other things, the cancellation of allrankings of celebrities. The rankings of music, film and television works are still allowed, butthe network platforms should optimize and adjust ranking rules to focus on the art worksthemselves and professional evaluation. Furthermore, minors are not allowed to make virtualgifting or spending money on supporting idols, or act as the organizer or manager of a fangroup. As of the Latest Practicable Date, we have taken measures specified in this notice to theextent applicable to our business, including removing the function of star power list on ourplatform.

On August 27, 2021, the CAC issued a discussion draft of Administrative Provisions onAlgorithm Recommendation of Internet Information Services (《互聯網信息服務算法推薦管理規定(徵求意見稿)》), which provides that algorithms recommendation service providers arenot allowed to use algorithms to register false user accounts, block information, give excessiverecommendations, and users should be given the option to easily turn off algorithmrecommendation services. Although the CAC has solicited comments on this draft since August27, 2021, there is no timetable as to when it will be enacted. As such, substantial uncertaintiesexist with respect to its enactment timetable, final content, interpretation and implementation.If the draft of the Administrative Provisions on Algorithm Recommendation of InternetInformation Services is enacted as proposed, we may need to further adjust our business andoperations. Under this draft, one of the key requirements is that the algorithm recommendationservice providers should publicly disclose the basic principles, purposes, intention, andoperating mechanism of their algorithm-related products. In this regard, we have publiclydisclosed the operation mechanism for “Weibo hot search” in the Weibo Hot SearchManagement Rules, which are posted as a Weibo community announcement. We have alsoprovided an option settings for our users to adjust the algorithm-driven recommendationssettings for content and advertisements. A user can click to deactivate “personalized adsrecommendation” function to lower the relevancy of the ads pushed to this user, and todeactivate “personalized content recommendation” function to lower relevancy of the contentrecommended to this user. We believe our initiatives will satisfy several key requirementsunder the draft Administrative Provisions on Algorithm Recommendation of InternetInformation Services to the extent possible. However, we cannot assure you that the PRCregulatory authorities will not take a view contrary to ours due to substantial uncertainties withrespect to the enactment timetable, final content, interpretation and implementation of thisdraft. We have been making efforts to adapt our business further to comply with otherapplicable requirements under this draft. We have been advised by our PRC Legal Adviser thatour current approaches are in compliance with effective laws and regulations for algorithmrecommendation in all material aspects as of the date of this document, however, since the draftAdministrative Provisions on Algorithm Recommendation of Internet Information Services hasnot been enacted as of the date of this document, the potential impact on our businessoperations is still substantially uncertain. In the event the draft is eventually enacted, theimpact on our SIG recommendation engine still depends largely on the number of users who

actually turn off our algorithm recommendation services. If such opt-out ratio turns out to beon the high end, the advertisement efficiency on our platform may ultimately be lowered andour business operations may be adversely affected.

On September 17, 2021, the CAC, together with eight other governmental authorities, jointlyissued the Guidelines on Strengthening the Comprehensive Regulation of Algorithm forInternet Information Services (關於加強互聯網信息服務算法綜合治理的指導意見), whichprovides that daily monitoring of data use, application scenarios and effects of algorithms shallbe carried out by the relevant regulators, and security assessments of algorithm shall beconducted by the relevant regulators. The guidelines also provide that an algorithm filingsystem shall be established and classified security management of algorithms shall bepromoted. The Company will closely monitor the regulatory development and adjust itsbusiness operation from time to time to comply with the regulations over algorithm.

On August 20, 2021, the SCNPC promulgated the Personal Information Protection Law of thePeople’s Republic of China (《中華人民共和國個人信息保護法》) (the “Personal InformationProtection Law”), effective from November 1, 2021. The Personal Information Protection Lawrequires, among others, that (i) the processing of personal information should have a clear andreasonable purpose which should be directly related to the processing purpose, in a method thathas the least impact on personal rights and interests, and (ii) the collection of personalinformation should be limited to the minimum scope necessary to achieve the processingpurpose to avoid the excessive collection of personal information. Different types of personalinformation and personal information processing will be subject to various rules on consent,transfer, and security. Entities handling personal information shall bear responsibilities fortheir personal information handling activities, and adopt necessary measures to safeguard thesecurity of the personal information they handle. Otherwise, the entities handling personalinformation could be ordered to correct, or suspend or terminate the provision of services, andface confiscation of illegal income, fines or other penalties.

On August 17, 2021, the State Administration for Market Regulation issued a discussion draftof Provisions on the Prohibition of Unfair Competition on the Internet (《禁止網絡不正當競爭行為規定(公開徵求意見稿)》), under which business operators should not use data oralgorithms to hijack traffic or influence users’ choices, or use technical means to illegallycapture or use other business operators’ data. Furthermore, business operators are not allowedto (i) fabricate or spread misleading information to damage the reputation of competitors, or(ii) employ marketing practices such as fake reviews or use coupons or “red envelopes” toentice positive ratings.

On July 30, 2021, the State Council promulgated the Regulations on Security Protection ofCritical Information Infrastructure (《關鍵信息基礎設施安全保護條例》), effective onSeptember 1, 2021. According to the Regulations on Security Protection of Critical InformationInfrastructure, a “critical information infrastructure” has the meaning of an important networkfacility and information system in important industries such as public communications andinformation services, energy, transportation, water conservancy, finance, public services,e-government, national defense technology, etc., as well as other important network facilitiesand information systems that may seriously endanger national security, the national economy,the people’s livelihood, or the public interests in the event of damage, loss of function, or dataleakage. The competent governmental departments and supervision and managementdepartments of the aforementioned important industries will be responsible for (i) organizingthe identification of critical information infrastructures in their respective industries inaccordance with certain identification rules, and (ii) promptly notifying the identified operatorsand the public security department of the State Council of the identification results.

On July 10, 2021, the CAC published a discussion draft of the proposed amended Measures forCybersecurity Review (《網絡安全審查辦法(修訂草案徵求意見稿)》), which provides that therelevant operators must apply with the Cybersecurity Review Office for a cybersecurity reviewunder the following circumstances: (i) operators of “critical information infrastructure” or dataprocessors holding over one million users’ personal information when listing abroad (國外上市), (ii) operators of “critical information infrastructure” that intend to purchase internetproducts and services that will or may affect national security, and (iii) data processors carryingout data processing that will or may affect national security. The CAC solicited comments onthis draft, but there is no timetable as to when it will be enacted. As such, substantialuncertainties exist with respect to its enactment timetable, final content, interpretation andimplementation. As of the date of this document, the amended Measures for CybersecurityReview have not been formally adopted. See “Risk Factors — Substantial uncertainties existwith respect to the interpretation and implementation of cybersecurity related regulations andcybersecurity review as well as any impact these may have on our business operations.” Thediscussion draft of the proposed amended Measures for Cybersecurity Review does not providedetailed explanation or interpretation of the conditions or procedures for listing abroad or anyadditional requirements.

The CAC, as the regulator in charge of cybersecurity and the identification of operators of“critical information infrastructure” in the internet sector, maintains regular communicationwith, and supervision over, major internet companies like us. Under the current PRCcybersecurity laws, operators of “critical information infrastructure” that intend to purchaseinternet products and services that will or may affect national security must apply for acybersecurity review. See “Regulatory Overview — Regulations on Information Security.” Asadvised by our PRC Legal Adviser, the scope of operators of “critical informationinfrastructure” under the current regulatory regime remains unclear and is subject to thedecisions of the relevant PRC government authorities that have been delegated the authority toidentify operators of “critical information infrastructure” in their respective jurisdictions(including regions and industries). In addition, the requirement that data processors carryingout data processing that will or may affect national security will be subject to cybersecurityreview is new to the proposed draft amendments to the Measures for Cybersecurity Review,and is similarly ambiguous with respect to identifying which data processing activities impactor may impact cybersecurity. Therefore, it is not possible for us to state with certainty how thisproposed draft amendment may ultimately affect our products and services. The PRCgovernment authorities have wide discretion in the interpretation and enforcement of these law,including the identification of operators of “critical information infrastructure”, theinterpretation and enforcement of requirements potentially applicable to such operators of“critical information infrastructure” and identifying which data processing activities impact ormay impact cybersecurity. As a major internet platform, we are at risk of being deemed to bean operator of “critical information infrastructure” or a data processor meeting the abovecriteria under PRC cybersecurity laws. In such case, we would be required to fulfill variousobligations as required under PRC cybersecurity laws and other applicable laws for suchoperators of “critical information infrastructure” and data processors meeting the abovecriteria, including, among others, setting up a special security management organization,organizing regular cybersecurity education and training, formulating emergency plans forcyber security incidents and conducting regular emergency drills. In addition, although theinternet products and services we purchase are primarily bandwidth, copyright content andmarketing services, we may be subject to cybersecurity review when purchasing those. As ofthe date of this document, we have not been involved in any investigations or cybersecurityreviews by the CAC for making those purchases of internet products and services during theTrack Record Period, and we have not received any inquiry, notice, warning, or sanction insuch respect. If a cybersecurity review for any of our activities is required, we will actively

cooperate with the CAC to conduct such cybersecurity review. We have already met several keyobligations currently applicable to operators of “critical information infrastructure,” includingsetting up a special security management organization, organizing regular cybersecurityeducation and training, formulating emergency plans for cyber security incidents, andconducting regular emergency drills. We are not able to fulfill the relevant obligations that areonly applicable and available if we are recognized as an operator of “critical informationinfrastructure,” such as conducting network security inspections and risk assessments oncritical information infrastructure at least once a year either through self-assessment or througha cybersecurity service agency, timely correcting any security issues discovered, and reportingrelevant matters as required by the security protection departments. If we are deemed to be anoperator of “critical information infrastructure” or a relevant data processor, we may need totake measures to meet these obligations, which may disrupt our operations and adversely affectour business, results of operations and financial condition. On November 14, 2021, the CACpublished a discussion draft of the Management Measures for Internet Date Security (《網絡數據安全管理條例(徵求意見稿)》) or the Draft Measures for Internet Data Security, whichprovides that the data processors conducting the following activities shall apply forcybersecurity review in accordance with the relevant regulations: (i) merger, reorganization orseparation of Internet platform operators that have acquired a large number of data resourcesrelated to national security, economic development or public interests affects or may affectnational security; (ii) listing abroad (國外上市) of data processors processing over one millionusers’ personal information; (iii) listing in Hong Kong which affects or may affect nationalsecurity; (iv) other data processing activities that affect or may affect national security. TheCAC solicited comments on this draft, but there is no timetable as to when it will be enacted.As such, substantial uncertainties exist with respect to its enactment timetable, final content,interpretation and implementation, especially the detailed explanation or interpretation of thestandard for determining whether a listing in Hong Kong “affects or may affect nationalsecurity.” As of the date of this document, the Draft Measures for Internet Data Security havenot been formally adopted. See “Risk Factors – Substantial uncertainties exist with respect tothe interpretation and implementation of cybersecurity related regulations and cybersecurityreview as well as any impact these may have on our business operations.” In addition, the DraftMeasures for Internet Data Security also provides that (i) the operators of large Internetplatforms who set up headquarters or, operation centers or R&D centers overseas (境外) shallreport to the national cyberspace administration and competent authorities and (ii) a dataprocessor processing important data or going public overseas (境外) shall conduct an annualdata security assessment by themselves or entrust a data security service institution to do so,and submit the data security assessment report of the previous year to the local branch of CACbefore January 31 of each year. See “Regulatory Overview – Regulations on InformationSecurity.” On July 6, 2021, the General Office of the Central Committee of the CommunistParty of China and the General Office of the State Council jointly issued the Opinions onStrictly Combating Illegal Securities Activities (《關於依法從嚴打擊證券違法活動的意見》),which emphasize on the prevention of illegal securities activities and tightened supervisionover overseas listings by China-based companies. The opinions aim to achieve this byestablishing a regulatory system and revising the existing rules for overseas listings by Chineseentities and affiliates, including potential extraterritorial application of China’s securities laws.As the opinions are new, official guidance and implementation rules have not been issued andthe final interpretation of and potential impact from these opinions remain unclear at this stage.See “Risk Factors — The approval of the CSRC or other PRC government authorities may berequired in connection with this offering under PRC law, and, if required, we cannot predictwhether we will be able to obtain such approval.” As of the date of this document, we have notreceived any inquiry, notice, warning, or sanction regarding this offering from the CSRC or anyother PRC government authorities.

On September 11, 2020, the Anti-Monopoly Commission of the State Council issuedAnti-Monopoly Compliance Guideline for Operators (《經營者反壟斷合規指南》), whichrequires operators to establish anti-monopoly compliance management systems under the PRCAnti-Monopoly Law to manage anti-monopoly compliance risks. On February 7, 2021, theAnti-Monopoly Commission of the State Council published Anti-Monopoly Guidelines for theInternet Platform Economy Sector (《國務院反壟斷委員會關於平台經濟領域的反壟斷指南》)that specified circumstances where an activity of an internet platform will be identified asmonopolistic act as well as concentration filing procedures for business operators, includingthose involving variable interest entities. In August 2021, the SAMR issued two investigationnotices to Weimeng Chuangke regarding alleged illegal concentration of business operatorsunder the Anti-Monopoly Law, among which, one resulted in a fine of RMB500,000 forconcentration of business operators without prior filing pursuant to the Anti-Monopoly Law(中華人民共和國反壟斷法) and the other one is still under investigation as of the date of thisdocument. Weimeng Chuangke is actively cooperating with the SAMR on such investigation.We are not able to predict the status or the results of the investigation at this stage. Accordingto the PRC Anti-Monopoly Law (中華人民共和國反壟斷法), if a business operator carries outa concentration in violation of the law, the relevant authority shall order the business operatorto terminate the concentration, dispose of the shares or assets or transfer the business withina specified time limit, or take other measures to restore the pre-concentration status, andimpose a fine of up to RMB500,000. As such, our PRC legal adviser is of the view that wecould be subject to fines of up to RMB500,000 and other legal actions by the SAMR for suchconcentration. On October 23, 2021, the Standing Committee of the National People’sCongress issued a discussion draft of the amended Anti-Monopoly Law, which proposes toincrease the fines for illegal concentration of business operators to no more than ten percentof its last year’s sales revenue if the concentration of business operator has or may have aneffect of excluding or limiting competitions; or a fine of up to RMB5 million if theconcentration of business operator does not have an effect of excluding or limiting competition.The draft also proposes that the relevant authority shall investigate a transaction where thereis any evidence that the concentration has or may have the effect of eliminating or restrictingcompetitions, even if such concentration does not reach the filing threshold. See “RiskFactors–Any failure or perceived failure by us to comply with the Anti-Monopoly Guidelinesfor Internet Platforms Economy Sector and other PRC anti-monopoly laws and regulations mayresult in governmental investigations or enforcement actions, litigation or claims against us andcould have an adverse effect on our business, financial condition and results of operations.”

On October 26, 2021, the CAC issued draft Administrative Provisions on the Account Namesof Internet Users (互聯網用戶賬號名稱信息管理規定(徵求意見稿)), revising the Regulationson the Administration of Internet User Account Names (互聯網用戶賬號名稱管理規定) thattook effect on March 1, 2015. This draft provides that when registering an internet account, theuser shall execute an agreement with the Internet user account services platform, provideauthentic identity information, and obey the rules of the platform for content production andaccount management, and the platform conventions and service agreement. Internet useraccount service platforms shall establish, improve and strictly implement, among others,account name information management system, information content security system, andpersonal information protection system. Internet user account service platforms should alsoestablish an account name information dynamic check patrol system for the verification of realidentity information, improve their technical measures for purposes of account informationlegal compliance, and support account name authenticity checks. When an Internet useraccount is in violation of the provisions of this draft, the Internet user account service platformshall suspend the service and inform the user to correct the issue within a limited time; and ifthe user refuses to correct it, the account shall be terminated. Although the CAC has solicited

comments on this draft until November 10, 2021, there is no timetable as to when it will beenacted. As such, substantial uncertainties exist with respect to its enactment timetable, finalcontent, interpretation and implementation. If such draft is enacted as proposed, it would becostly for us to make more efforts on monitoring and managing user account names to complywith these requirements.

On October 8, 2021, the National Development and Reform Commission issued a discussiondraft of the Negative List for Market Access (2021 Version) (市場准入負面清單(2021年版)),which provides that, among others, non-state-capitalized entities shall not conduct the businessof news collecting, editing, releasing and reporting. Weibo does not collect, edit, release orreport news by itself. Weibo holds an Internet News and Information Service License, whichallows it to provide the service of reposting news information and operating a platform todisseminate news information. The draft Negative List also provides that non-state-capitalizedentities shall not engage in live streaming of political, economic, military, diplomatic, majorsocial, cultural, scientific and technological, health, education, sports and other activities andevents related to political direction, public opinion orientation and value orientation. The scopeof live streaming business under this list is relatively broad and vague, and is subject to furtherclarifications and interpretations by the regulator. However, as we generated less than 5% ofour net revenues from live streaming, we do not believe this new requirement would have amaterial adverse impact on our business operations or financial results. The NDRC hassolicited comments on this draft since October 8, 2021, and there is no timetable as to whenit will be enacted. As such, substantial uncertainties exist with respect to its enactmenttimetable, final content, interpretation and implementation. If the draft of the Negative List forMarket Access (2021 Version) is enacted as proposed, we may need to further adjust ourbusiness and operations and our business operations may be adversely affected.

Based on the foregoing and the currently effective PRC laws, we and our PRC Legal Adviserare of the view that the above recent changes in PRC laws and regulations will not affect ourcompliance with laws and regulations in any material aspects as of the date of this document.As of the date of this document, except as disclosed above, we were not involved in anyenquiry, review or investigations by the CAC or other authorities in respect of the aboverecently promulgated laws and regulations.

The following discussion and analysis of our financial condition and results of operationsshould be read in conjunction with our consolidated financial statements and the relatednotes included in the Accountant’s Report in Appendix IA and in “Business.” Thisdiscussion contains forward-looking statements that involve risks and uncertainties. Ouractual results and the timing of selected events could differ materially from thoseanticipated in these forward-looking statements as a result of various factors, includingthose set out under “Risk Factors” and elsewhere in this document. We have prepared ourconsolidated financial statements in accordance with U.S. GAAP. Our fiscal year ends onDecember 31 and references to fiscal years 2018, 2019 and 2020 are to the fiscal yearsended December 31, 2018, 2019 and 2020, respectively.

OVERVIEW

As a leading social media platform for people to create, discover and distribute content inChina and the global Chinese communities, Weibo combines the means of public self-expression in real time with a powerful platform for social interaction, content creation anddistribution. Since our inception in August 2009, we have achieved significant scale. In June2021, we had 566 million MAUs and 246 million average DAUs. Approximately 94% of ourMAUs in June 2021 accessed Weibo through mobile devices at least once during the month.

We offer a wide range of advertising and marketing solutions to our customers, ranging fromkey accounts, which are mostly large brand advertisers, to small medium-sized enterprises,enabling them to promote their brands, products and services to our users. Advertising andmarketing services contribute to the majority of our revenues, mainly including the sale ofsocial display advertisements and promoted feeds. We have developed and are continuouslyrefining our interest-based recommendation engine, which enables our customers to performsocial marketing and target audiences based on user demographics, social relationships andinterests to achieve greater relevance, engagement and marketing effectiveness on Weibo.

The value we create for our users and customers is enhanced by our platform partners, whichinclude content creators such as KOLs, media outlets and other organizations with mediarights, MCNs, which are professional agencies for influencers, self-medias and app developers.Our platform partners contribute a vast amount of content to Weibo, which generates userengagement and is virally distributed across the platform, enriching user experience andincreasing Weibo’s monetization opportunities. We have revenue-sharing arrangements withsome of our platform partners, such as live streaming agencies, influencers, MCNs and gamedevelopers.

Weibo began monetization in 2012 primarily through the sale of advertising and marketingservices and, to a lesser extent, through value added services, mainly including VIPmembership, live streaming, and game related services. We place great emphasis on productinnovation and our steady stream of introductions of new advertisement products has led tosolid and healthy revenue growth since our IPO, despite the adverse impact from COVID-19in 2020. Our revenues in 2018, 2019 and 2020 were US$1,718.5 million, US$1,766.9 millionand US$1,689.9 million, respectively. Our revenues increased from US$710.8 million for thesix months ended June 30, 2020 to US$1,033.4 million for the six months ended June 30, 2021.We had a net income attributable to Weibo’s shareholders of US$571.8 million in 2018,US$494.7 million in 2019 and US$313.4 million in 2020. We had a net income attributable toWeibo’s shareholders of US$250.5 million for the six months ended June 30, 2020 andUS$130.8 million for the six months ended June 30, 2021.

FACTORS AFFECTING OUR RESULTS OF OPERATIONS

Our business and operating results are affected by general factors affecting the social mediaindustry in China, which include:

• the extent to which social media continues to grow in popularity and becomes furtherintegrated into people’s everyday lives in China;

• the intensity of competition both for the time and attention of internet users and for theadvertising and marketing spending of brands and businesses that market to consumers;

• the changes in China’s or global economies, policies, and regulatory environment; and

• continued mobile internet penetration and infrastructure development.

Unfavorable changes in any of these general factors could negatively affect demand for ourproducts and services and adversely affect the results of our operations. In addition to thegeneral factors affecting the social media industry in China, the specific factors affecting ourresults of operations include the following:

Scale and Engagement of Our User Base. Our revenues are ultimately affected by the scaleof our user base, and the strategies we pursue to achieve user growth may affect our costs andexpenses and results of operations. We have experienced solid user growth since our inceptionin 2009. As the size of our user base increases to an even larger scale and as we become morepenetrated in China, our user growth rate may decrease. Due to the media nature of ourplatform, the growth of our users may not be linear. In general, the penetration of Weibo amonginternet users in the more economically developed tier 1 and tier 2 cities in China who useWeibo is higher than in other parts of China. Our ability to grow our active user base willdepend in part on the success of our strategies to attract additional users from lower-tier citiesand towns in China while maintaining or growing our user base in tier 1 and tier 2 cities.

Changes in user engagement could affect our results of operations, especially since we beganadding monetization features to our social platform. We need to motivate our users to engageactively on our platform to secure an abundant supply of user-generated content, to enticecontent creators to share even more content, and to ensure that we have a broad audience forour advertising and marketing services. Video, particularly in the form of short video and livestreaming, is gaining more popularity in China and has become an important way for our usersto engage and interact on Weibo. Our ability to provide an easy-to-use infrastructure for ourusers to create and share video as well as consume video will largely impact our userexperience.

We plan to continue to enhance Weibo’s user experience and engagement by improving ourproduct features, offering new products, expanding our content offerings through collaborationwith platform partners, developing and integrating with applications and continuing to refineWeibo’s SIG recommendation engine to improve content relevancy and advertisement targetingcapabilities.

Products and Services Innovation. Social media is an innovative and fast-changing field, andwe must develop innovative products and services that meet the disparate needs of users,advertising and marketing customers and platform partners and roll them out on a timely basiswhile controlling our product development expenses. We plan to continue to make significantinvestments in product development and refining the capabilities of Weibo’s SIGrecommendation engine, and we may invest in or acquire businesses or assets to enhance ourproducts, services and technical capabilities.

Content Ecosystem. Our success depends on our ability to provide users with interesting anduseful content, which in turn depends on the content contributed by our users. Content creators,especially KOLs, contribute content to Weibo to grow their fan base and enhance theirinfluence. We provide content creators with the opportunity to monetize their social assets onWeibo through advertising, e-commerce, subscription, tipping and other means. If contentcreators do not see significant value from their social marketing activities on Weibo and findmonetization on Weibo inadequate, we may have to subsidize them through direct content costpayout, which may have an adverse and material impact on our business, financial conditionand operating results. Alternatively, content creators may choose to contribute less or nocontent to Weibo, which may cause our user base and user engagement to decline and ourcustomers to view our products and services as less attractive for advertising and marketingpurposes. If that were to occur, our customers would reduce their spending on our platform.

Monetization. We started monetization in 2012 and have since experienced solid revenuegrowth. We generate revenues primarily from customers who purchase advertising andmarketing services, and, to a lesser extent, from value-added services. Our monetization modelis evolving and sophisticated. Therefore, we are unable to gauge the period-to-period growthof our revenues based on any particular user traffic metric. Furthermore, our ability to monetizeour user traffic depends to a large degree on how well the demographic profile and socialinterests of our users fit the audience profile that our advertising and marketing customers hopeto reach at any given time. Our advertising and marketing customers include both largecompanies and SMEs that seek a full spectrum of online advertising and marketing servicesranging from brand awareness to interest generation, sales conversion and loyalty marketing.We plan to increase the monetization of our platform by growing our user base and userengagement, and managing advertisement inventory and advertising load more effectivelywithout adversely affecting user experience. Meanwhile, in order to continue to increase theefficiency of monetization, we need to stay innovative to improve the targeting capabilities ofour advertising and marketing offerings and develop new advertisement products, formats andcapabilities. We also plan to further diversify our monetization through growing value-addedservices.

We have been exploring various ways of monetization since 2012. For example, in 2016, weupgraded our advertisement system to allow SMEs to purchase brand advertisements and keyaccounts to purchase promoted feeds, as well as introduced video advertisements. We alsointroduced promoted search to customers to sponsor key words or topics alongside users’search behaviors in 2016. In 2017 and 2020, we initiated two rounds of comprehensive revampon our advertisement system to drive bidding efficiency as well as diversify our advertisingofferings. We generate revenues from value-added services primarily by providingmembership, live streaming and online game services. We have been exploring monetizationopportunities in value-added services through investment in various areas, including ouracquisitions of a live streaming business in 2018 and a company operating several onlineinteractive entertainment apps in China including “Pocket Werewolves” in 2020.

Investment in Technology Infrastructure. Our technology infrastructure is critical toproviding users, customers and platform partners access to our platform, particularly duringmajor events when activities on our platform increase substantially. We must continue toupgrade and expand our technology infrastructure to keep pace with the growth of our businessand to ensure that technical difficulties do not detract from user experience or deter new users,customers or platform partners from accessing our platform. As 4G and Wi-Fi become morewidely available in China and 5G has been gradually introduced to people’s daily life, weexpect our users to share and consume more content in rich media format, such as photo, videoand audio, which will require more infrastructure capacity, and costs to support, than textfeeds. To further expand our capabilities to satisfy technology infrastructure demands,especially those arising from major media events and increasing video usage, we work with

third-party service providers to procure bandwidth and other infrastructure services. Ourability to derive greater cost efficiency from infrastructure demands will depend on factorsincluding our ability to negotiate a lower unit price with third-party vendors over time and themix of services provided by third-party vendors and SINA, our controlling shareholder.

Marketing and Brand Promotion. Our brand recognition is key to our growth in both userscale and engagement to achieve platform expansion. On top of user base expansion, we haveoptimized our channel investment strategy along with relevant product and operational efforts,to focus on enhancing user engagement, which resulted in higher user acquisition efficiencywith disciplined sales and marketing spending.

Investment in Talent. Our employee headcount has increased significantly since our inception.There is heavy demand in China’s internet industry for talented technical, sales and marketing,management and other personnel with necessary experience and expertise. We must recruit,retain and motivate talented employees while controlling our personnel-related expenses,including stock-based compensation.

IMPACT OF COVID-19 ON OUR OPERATIONS AND FINANCIAL PERFORMANCE

Substantially all of our revenues and workforce are concentrated in China. Our results ofoperations and financial condition in 2020 have been affected by the spread of COVID-19. Theextent to which COVID-19 impacts our financial position, results of operations and cash flowsin 2021 will depend on the future developments of the outbreak, which are highly uncertain andcannot be predicted, including new information which may emerge concerning the severity ofCOVID-19, the actions to contain the coronavirus or treat its impact, and the availability ofvaccine and treatment for COVID-19, among others. In addition, our financial position, resultsof operations and cash flows could be adversely affected to the extent that the outbreak harmsthe Chinese economy in general.

In early 2020, to contain the spread of COVID-19, the Chinese government had taken certainemergency measures, including extension of the Lunar New Year holidays, implementation oftravel bans, blockade of certain roads and suspension of operation of factories and businesses.These emergency measures have been significantly relaxed by the Chinese government as ofthe Latest Practicable Date. However, there have been occasional outbreaks of COVID-19 invarious cities in China, and the Chinese government may again take measures to keepCOVID-19 in check. Our headquarters are located in Beijing, and we currently lease themajority of our offices in various parts of China to support our operations. This outbreak ofcommunicable disease has caused, and may cause again in the future, companies, including usand certain of our customers and content partners, to implement temporary adjustment of workschemes allowing employees to work from home and adopt remote collaboration. We havetaken measures to reduce the impact of this epidemic outbreak, including upgrading ourtelecommuting system, monitoring our employees’ health on a daily basis, arranging shifts ofour employees working onsite and from home to avoid infection transmission and optimizingour technology system to support potential growth in user traffic. The outbreak of COVID-19has caused our advertising and marketing customers to reduce their advertising budgets, whichhas affected our advertising revenues and financial performance in 2020, particularly in its firsthalf. The COVID-19 pandemic has resulted in negative impact to our total revenues, slowercollection of accounts receivables, and additional allowance for credit losses. Our advertisingbusiness has been gradually recovering, underpinned by improved advertiser sentiment,following the effective control of the domestic outbreaks and work resumption. We will payclose attention to the development of the COVID-19 pandemic, including subsequent outbreaksdriven by new variants of COVID-19, perform further assessment of its impact and takerelevant measures to minimize the impact. We were exempt from payment of cultural businessconstruction fees for the fiscal years of 2020 and 2021 as part of the measures taken by the

government to ease the negative impact from the COVID-19 pandemic. As a result, we wereexempt from payment of cultural business construction fees of US$24.6 million in 2020 andUS$11.5 million in the six months ended June 30, 2021. See also “Risk Factors — RisksRelating to Our Business — We face risks related to health epidemics and other outbreaks, suchas the outbreak of COVID-19, as well as natural disasters, which could significantly disrupt ouroperations and adversely affect our business, financial condition or results of operation.”

As of June 30, 2021, our total cash, cash equivalents and short-term investments wereUS$2,935.9 million. Our principal sources of liquidity have been cash from operations and netproceeds from issuance of unsecured senior notes. We believe this level of liquidity issufficient to successfully navigate an extended period of uncertainty.

TAXATION

We generate the majority of our operating income from our PRC operations and have recordedincome tax provisions for the periods presented.

According to Maples and Calder (Hong Kong) LLP, our Cayman Islands counsel, the CaymanIslands currently levies no taxes on individuals or corporations based upon profits, income,gains or appreciation, and there is no taxation in the nature of inheritance tax or estate duty.There are no other taxes likely to be material to us levied by the Government of the CaymanIslands, except for stamp duties, which may be applicable on instruments executed in, or afterexecution brought within, the jurisdiction of the Cayman Islands. The Cayman Islands is nota party to any double tax treaties that are applicable to any payments made to or by ourcompany. There are no exchange control regulations or currency restrictions in the CaymanIslands.

Our subsidiary incorporated in Hong Kong, Weibo HK, is subject to 16.5% Hong Kong profittax on its taxable income generated from operations in Hong Kong for the years of assessment2017/2018, 2018/2019 and 2019/2020. Commencing from the year of assessment 2018/2019,the first HK$2 million of profits earned by our subsidiary incorporated in Hong Kong will betaxed at half the current tax rate (i.e., 8.25%) while the remaining profits will continue to betaxed at the existing 16.5% tax rate. Under the Hong Kong tax laws, we are exempted from theHong Kong income tax on our foreign-derived income. Hong Kong does not impose awithholding tax on dividends.

Our PRC subsidiaries, VIEs and VIEs’ subsidiaries are incorporated in China and are subjectto enterprise income tax on their taxable income in China at a standard rate of 25% if they arenot eligible for any preferential tax treatment. Taxable income is based on the entity’s globalincome as determined under PRC tax laws and accounting standards. Preferential taxtreatments will be granted to companies conducting businesses in certain encouraged sectorsand to entities qualified as a “software enterprise,” “key software enterprise” and/or “high andnew technology enterprise.” Weibo Technology, our PRC subsidiary, was qualified as a“software enterprise” and was entitled to an exemption from the enterprise income tax for twoyears beginning 2015, its first accumulative profitable year, and a 50% reduction (to a tax rateof 12.5%) for the subsequent three years from 2017 to 2019. Although Weibo Technology wasqualified as a “software enterprise” in 2020, it did not enjoy a reduced tax rate for its “softwareenterprise” status as it has been five years since its first profitable year of 2015. WeiboTechnology completed its filings as a “key software enterprise” with the tax authority in 2018,2019 and 2020 for its status of 2017, 2018 and 2019, and, therefore, was entitled to enjoy afurther reduced preferential tax rate of 10% for 2017, 2018 and 2019. The qualification as a“key software enterprise” is subject to annual evaluation and approval by the relevantauthorities in China, and we will only recognize the preferential tax treatment of “key softwareenterprise” status when approval from the relevant authorities is obtained, usually one year in

arrears. Weibo Technology was also granted the “high and new technology enterprise” statusfor the fiscal years from 2017 to 2022, which entitled the qualified entity to a preferential taxrate of 15% in 2020 and 2021. Its qualification as a “high and new technology enterprise” issubject to annual evaluation and a three-year review by the relevant authorities in China. Inaddition, certain of our other PRC entities also qualify as a “software enterprise,” and/or “highand new technology enterprise,” and currently enjoy the respective preferential tax treatments.

According to the relevant PRC laws and regulations, enterprises engaging in research anddevelopment activities were entitled to claim 150% of their research and development expensesincurred as tax deductible expenses when determining their assessable profits for that year (the“R&D Deduction”). The PRC State Taxation Administration announced in September 2018 thatenterprises engaging in research and development activities would be entitled to claim 175%of their research and development expenses as R&D Deduction from January 1, 2018 toDecember 31, 2020.

Our PRC subsidiaries, VIEs and VIEs’ subsidiaries are also subject to VAT and relatedsurcharges at a combined rate of 6.7%. Our advertising and marketing revenues are also subjectto cultural business construction fees at a rate of 3%, which has been reduced to 1.5% sinceJuly 1, 2019, valid until December 31, 2024. The cultural business construction fees wereexempted for the fiscal years of 2020 and 2021 as part of the measures taken by the governmentto ease the negative impact from the COVID-19 pandemic. As a result, we were exempt frompayment of cultural business construction fees of US$24.6 million in 2020 and US$11.5million in the six months ended June 30, 2021.

Dividends paid by our subsidiary in China, Weibo Technology, to our intermediary holdingcompany in Hong Kong, Weibo HK, will be subject to PRC withholding tax at a rate of 10%unless they qualify for a special exemption. If Weibo HK satisfies all the requirements underthe Arrangement between the PRC and the Hong Kong Special Administrative Region on theAvoidance of Double Taxation and Prevention of Fiscal Evasion with respect to Taxes onIncome and receives approval from the relevant tax authority, then dividends paid by WeiboTechnology to Weibo HK will be subject to a withholding tax rate of 5% instead. See “RiskFactors — Risks Relating to Doing Business in the People’s Republic of China — Anylimitation on the ability of our PRC subsidiaries to make payments to us, or the taximplications of making payments to us, could have a material adverse effect on our ability toconduct our business or our financial condition.”

If our holding company in the Cayman Islands, Weibo Corporation, were deemed to be a “PRCresident enterprise” under the Enterprise Income Tax Law, it would be subject to enterpriseincome tax on its global income at a rate of 25%. See “Risk Factors — Risks Relating to DoingBusiness in the People’s Republic of China — We and/or our Hong Kong subsidiary may beclassified as a ‘PRC resident enterprise’ for PRC enterprise income tax purposes. Suchclassification would likely result in unfavorable tax consequences to us and our non-PRCshareholders and have a material adverse effect on our results of operations and the value ofyour investment.”

If Weibo HK were deemed to be a “PRC resident enterprise” under the Enterprise Income TaxLaw, then dividends payable by Weibo HK to Weibo Corporation may become subject to 10%PRC dividend withholding tax. Under such circumstances, it is not clear whether dividendspayable by Weibo Technology to Weibo HK would still be subject to PRC dividend withholdingtax and whether such tax, if imposed, would be imposed at a rate of 5% or 10%. See “RiskFactors — Risks Relating to Doing Business in the People’s Republic of China — Anylimitation on the ability of our PRC subsidiaries to make payments to us, or the taximplications of making payments to us, could have a material adverse effect on our ability toconduct our business or our financial condition.”

(1) On January 1, 2018, we adopted new revenue guidance ASC Topic 606, “Revenue from Contracts withCustomers,” using the modified retrospective method applied to those contracts which were not completed asof January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under Topic606, while prior period amounts are not adjusted and continue to be reported in accordance with our historicaccounting method under Topic 605. Topic 606 requires the presentation of VAT recognized in revenues from“gross” to “net,” which results in equal decrease in revenues and cost of revenues, and recognition of revenuesand expenses at fair value for advertising barter transactions.

(2) We recorded US$117.7 million, US$97.8 million and US$152.0 million in advertising and marketing revenuesfrom Alibaba during 2018, 2019 and 2020, respectively.

(4) We adopted ASU 2016-13, “Financial Instruments — Credit Losses (Topic 326), Measurement of Credit Losseson Financial Instruments” in the fiscal year of 2020. The guidance requires the measurement and recognitionof expected credit losses for financial assets held at amortized cost that an entity does not expect to collect overthe asset’s contractual life, considering past events, current conditions, and reasonable and supportableforecasts of future economic conditions.

(5) We adopted ASU 2016-01 “Classification and Measurement of Financial Instruments” beginning the firstquarter of fiscal year 2018. After the adoption of the new accounting update, we measure investments in equitysecurities, other than equity method investments, at fair value through earnings. For those investments withoutreadily determinable fair values, we elected to record these investments at cost, less impairment, and plus orminus subsequent adjustments for observable price changes. Changes in the basis of these investments arereported in current earnings.

(6) Investment related impairment includes impairment charges to equity investments, investment prepayments,and loans to and interest receivable from related parties.

(7) Each ADS represents one Class A ordinary share.

Six Months Ended June 30, 2021 Compared to Six Months Ended June 30, 2020 NetRevenues

Our total net revenues increased by 45% from US$710.8 million in the six months ended June30, 2020 to US$1,033.4 million in the six months ended June 30, 2021.

• Advertising and Marketing Revenues. Advertising and marketing revenues increased by45% from US$616.0 million in the six months ended June 30, 2020 to US$892.3 millionin the six months ended June 30, 2021. Revenues from advertising customers (excludingAlibaba) increased by 48% from US$552.7 million in the six months ended June 30, 2020to US$819.1 million in the six months ended June 30, 2021, primarily attributable to abroad-based increase in advertising demand and strong sales execution. Revenuesgenerated from Alibaba as an advertiser increased by 16% from US$63.3 million in thesix months ended June 30, 2020 to US$73.3 million in the six months ended June 30,2021. The advertising spending from Alibaba highly correlates to its own businessoperation, especially its marketing strategies, which fluctuates from time to time.

• Value-added Services Revenues. Value-added services revenues increased by 49% fromUS$94.8 million in the six months ended June 30, 2020 to US$141.0 million in the sixmonths ended June 30, 2021, primarily attributable to the increase of game-relatedrevenues from US$0.7 million for the six months ended June 30, 2020 to US$52.5 millionfor the six months ended June 30, 2021, contributed by the interactive entertainmentcompany acquired in the fourth quarter of 2020 and incremental revenues from onlinegame services, partially offset by the decrease in the revenues from live streamingbusiness from US$20.9 million to US$9.9 million as a result of the intense marketcompetitions.

2020 Compared to 2019

Our revenues decreased by 4% from US$1,766.9 million in 2019 to US$1,689.9 million in2020.

• Advertising and marketing revenues. Advertising and marketing revenues decreased by3% from US$1,530.2 million in 2019 to US$1,486.2 million in 2020. The decrease wasmainly due to the negative impact and uncertainties brought by the COVID-19 pandemic,particularly in the first half of 2020. Mobile advertising revenues accounted forapproximately 90% of our total advertising and marketing revenues in 2020, compared to87% in 2019, benefiting from the growth of advertiser preferences. The total number ofadvertisers was 1.6 million in 2020, compared to 2.4 million in 2019, while the averagespending per advertiser (excluding Alibaba) increased by 39% from US$593 in 2019 toUS$825 in 2020, both of which were primarily due to the churn of individual customerswith relatively lower advertising budgets.

Revenue from key accounts grew by 2% from US$729.3 million in 2019 to US$741.5million in 2020, largely attributable to the strong relationship between Weibo and brandadvertising customers, as Weibo demonstrated unique value proposition for customerswith our differentiated social advertising offerings and enhanced ad performance.

Revenue from SMEs decreased by 16% from US$703.2 million in 2019 to US$592.7million in 2020, mostly due to the relatively slower recovery pace of the SME sectorduring the COVID-19 pandemic and intense market competition.

Revenue generated from Alibaba as an advertiser increased by 55% from US$97.8 millionin 2019 to US$152.0 million in 2020. The expenditure from Alibaba on Weibo’s platformhighly correlates to its marketing strategies, which may fluctuate on an annual basis. Thesustained momentum of advertising spending from Alibaba reflects our strengthenedcooperation in driving value for brands and merchants to achieve branding plusperformance purposes through integrated advertisement campaigns on both platforms.Weibo remains a key platform for Alibaba in the fields of social marketing, e-commerceand fan economy.

• Value-added services revenues. Value-added services revenues decreased by 14% fromUS$236.7 million in 2019 to US$203.8 million in 2020. The decrease was mainly causedby the revenue decline from the Yizhibo live streaming business, which fell from US$76.7million in 2019 to US$39.3 million in 2020, resulting from the intense marketcompetition. The decrease was partially offset by (i) the revenue growth of our VIPmembership, which increased by US$15.8 million or 15% compared to 2019, resultingfrom the increase of revenue from users who were willing to pay for the content createdby our platform partners, and (ii) the revenue growth from game-related services byUS$8.2 million or 187% compared to 2019, mostly attributable to the interactiveentertainment company acquired in the fourth quarter of 2020.

2019 Compared to 2018

Our revenues increased by 3% from US$1,718.5 million in 2018 to US$1,766.9 million in2019. We faced various challenges in 2019, such as the unfavorable impact from the overalldepreciation of RMB against the U.S. dollar in 2019 compared to 2018, tightened regulationson certain industries, intensified market competition and so on.

• Advertising and marketing revenues. Advertising and marketing revenues increased by2% from US$1,499.2 million in 2018 to US$1,530.2 million in 2019. Mobile advertisingrevenues accounted for approximately 87% of our total advertising and marketingrevenues in 2019, compared to 83% in 2018, benefiting from the growth of both mobileusers as well as advertiser preferences. The total number of advertisers was 2.4 millionin 2019, compared to 2.9 million in 2018, mainly due to customer churn of SMEcustomers, as a result of mixed challenges from unfavorable macroeconomic conditionsand intense market competition. The average spending per advertiser (excluding Alibaba)increased by 26% from US$470 in 2018 to US$593 in 2019, primarily attributable to theincrease in spending by our recurring customers, and also a reflection of the churn ofSME customers with relatively lower advertising budgets.

Revenue from key accounts grew by 8% from US$674.0 million in 2018 to US$729.3million in 2019, largely attributable to the strong bond between Weibo and brandadvertising customers, as Weibo demonstrated unique value proposition for customerswith our differentiated social advertising offerings and enhanced ad performance.

Revenue from SMEs decreased slightly by 1% from US$707.5 million in 2018 toUS$703.2 million in 2019, primarily attributable to the unfavorable impact from theoverall depreciation of RMB against the U.S. dollar in 2019 compared to 2018. We alsofaced unfavorable supply and demand dynamics in the performance-based advertisingmarket and consequently intensified market competition.

Revenue generated from Alibaba decreased by 17% from US$117.7 million in 2018 toUS$97.8 million in 2019. The expenditure from Alibaba on Weibo’s platform highlycorrelates to its marketing strategies, which may fluctuate on an annual basis. Weiboremains a key platform for Alibaba in the fields of social marketing, e-commerce and faneconomy.

• Value-added services revenues. Value-added services revenues increased by 8% fromUS$219.3 million in 2018 to US$236.7 million in 2019. The increase was primarilyattributable to (i) the revenue growth of our VIP membership, which increased by 10%from US$98.2 million in 2018 to US$108.1 million in 2019 mainly as a result of theincrease of our user base, and (ii) the revenue growth of the Yizhibo live streamingbusiness acquired in the fourth quarter of 2018, which increased from US$28.0 million in2018 to US$76.7 million in 2019. Revenues from game-related services decreased by84% from US$27.3 million in 2018 to US$4.4 million in 2019, mainly because somegames had reached the end of their life cycles and a tightened regulatory environment inthis industry.

Costs and Expenses

Our costs and expenses primarily consist of cost of revenues, sales and marketing, productdevelopment, and general and administrative expenses, including costs and expenses allocatedfrom SINA during the periods presented.

Generaland administrative expenses primarily consist of personnel-related expenses, stock-basedcompensation, professional services fees, and provision of allowance for credit losses.

Six Months Ended June 30, 2021 Compared to Six Months Ended June 30, 2020

Our costs and expenses increased by 34% from US$546.6 million in the six months ended June30, 2020 to US$731.5 million in the six months ended June 30, 2021, primarily due to highermarketing expense and personnel-related cost.

• Cost of Revenues. Cost of revenues increased by 25% from US$137.7 million in the sixmonths ended June 30, 2020 to US$172.3 million in the six months ended June 30, 2021.The increase was primarily due to an increase of US$13.2 million in labor cost, anincrease of US$9.2 million in advertisement production cost, an increase of US$6.1million in revenue share cost, and an increase of US$5.6 million in turnover taxes.

• Sales and Marketing. Sales and marketing expenses increased by 41% from US$211.2million in the six months ended June 30, 2020 to US$298.4 million in the six monthsended June 30, 2021. The increase was primarily due to an increase of US$62.9 millionin marketing spend and promotional activities as we enhanced our marketing efforts afterthe COVID-19 became gradually contained in China, and an increase of US$21.5 millionin personnel-related expenses primarily due to an increase in our sales and marketing staffheadcount.

• Product Development. Product development expenses increased by 32% from US$150.4million in the six months ended June 30, 2020 to US$198.0 million in the six monthsended June 30, 2021. The increase was primarily due to an increase of US$29.7 millionin personnel-related expenses and an increase of US$3.8 million in stock-basedcompensation as we increased our research and development staff headcount, and anincrease of US$8.3 million in amortization of intangible assets mostly attributable to theacquisitions of JM Tech and the developer of Wuta beauty camera app.

• General and Administrative. General and administrative expenses increased by 33% fromUS$47.3 million in the six months ended June 30, 2020 to US$62.9 million in the sixmonths ended June 30, 2021. The increase was primarily due to the increase of US$24.0million in personnel-related expenses mainly driven by an increase in general andadministrative staff headcount, and an increase of US$3.1 million in professional servicesfees. The increase was partially offset by a decrease of US$14.8 million in provision ofallowance for credit losses as the outbreak of COVID-19 in 2020 adversely impacted thecollection of our accounts receivable.

2020 Compared to 2019

Our costs and expenses increased slightly by 1% from US$1,169.3 million in 2019 toUS$1,183.1 million in 2020.

• Cost of Revenues. Cost of revenues decreased by 8% from US$328.8 million in 2019 toUS$302.2 million in 2020. The decrease was largely due to the decline of US$34.1million in turnover taxes mainly resulting from the exemption of payment of culturalbusiness construction fees applicable to the advertising industries for the fiscal year of2020, and a decrease of US$20.1 million in revenue share cost primarily caused by thedecline in live streaming revenue. The decrease was partially offset by an increase ofUS$17.0 million in advertisement production cost, and an increase of US$10.0 million inlabor cost. We expect our cost of revenues to increase in absolute amount in theforeseeable future.

• Sales and Marketing. Our sales and marketing expenses decreased by 2% from US$465.3million in 2019 to US$455.6 million in 2020. The decrease was mostly from a reductionof US$21.4 million in marketing spend and promotional activities during the COVID-19pandemic, partially offset by an increase of US$9.4 million in personnel-related expense,mainly driven by an increase in employee headcount. We expect our sales and marketingexpenses to increase in absolute amount in the foreseeable future.

• Product Development. Our product development expenses increased by 14% fromUS$284.4 million in 2019 to US$324.1 million in 2020. The increase was primarilyattributable to a growth of US$22.7 million in personnel-related expenses arising from alarger product development team and higher salaries, and an increase of US$11.2 millionin infrastructure cost. We expect our product development expenses to increase inabsolute amount in the foreseeable future.

• General and Administrative. Our general and administrative expenses increased by 12%from US$90.7 million in 2019 to US$101.2 million in 2020, largely resulting from anincrease of US$14.6 million in provision of allowance for credit losses. We expect ourgeneral and administrative expenses to increase in absolute amount in the foreseeablefuture.

Income tax expenses were US$61.9 million in the six months ended June 30, 2021, comparedto US$56.6 million in the six months ended June 30, 2020. The increase in income tax expensesprimarily resulted from the profit growth from China operations for the six months ended June30, 2021, partially offset by decrease of deferred taxes charges related to fair value change ofinvestments from non-China operations.

We recorded income taxes of US$96.2 million, US$109.6 million and US$61.3 million in 2018,2019 and 2020, respectively, including a US$2.9 million deferred tax charge from the fair valuechange of investments by our non-China operations in 2020. The provision for income taxesfor China operations differs from the amounts computed by applying the statutory EIT ratemostly due to the preferential tax treatment that Weibo Technology enjoyed as a qualified“software enterprise” or “high and new technology enterprise” during the periods presented, aswell as the preferential tax treatment of “key software enterprise” status of 2017 to 2019benefited by the WFOE one year in arrears during the three-year period ended December 31,2020. Weibo Technology was entitled to a tax reduction of US$77.2 million, US$83.2 millionand US$55.1 million for 2018, 2019 and 2020, respectively. The WFOE further recognizedpreferential tax treatment of “key software enterprise” status and tax benefit of research anddevelopment super deduction of US$11.7 million for 2017 in 2018, US$21.5 million for 2018in 2019, and US$26.6 million for 2019 in 2020.

Income (loss) from non-China operations mainly included stock-based compensation, fairvalue changes through earnings on investments and investment related impairment recorded byour non-China subsidiaries. We recorded fair value change gain of US$210.2 million in 2019,which was mainly generated by Beijing Showworld Technology Co., Ltd., one of our investees,who completed its listing on Shanghai Stock Exchange through an equity reconstruction witha then-listed company at the end of 2019. We recorded investment related impairment ofUS$233.9 million in 2019 mainly due to the partial write off of US$214.7 million to thecarrying value of Yixia Tech Co., Ltd.

As of December 31, 2018, 2019, 2020 and June 30, 2021, our total cash, cash equivalents andshort-term investments were US$1,825.9 million, US$2,404.2 million, US$3,496.9 million andUS$2,935.9 million, respectively. Our principal sources of liquidity have been net proceedsfrom cash from operations and issuance of unsecured senior notes.

The decrease in our cash, cash equivalents and short-term investments as of June 30, 2021compared to that of December 31, 2020 was primarily due to cash paid to investments ofUS$960.4 million, loan to SINA of US$310.9 million, and prepayment for purchase of SINAPlaza of US$132.5 million, partially offset by US$338.4 million in cash provided by operatingactivities, proceeds from the disposal of and refund from investments of US$168.3 million andrepayment of loan by SINA of US$388.4 million. As of June 30, 2021, our consolidated entitieswithin China held US$1,466.0 million of cash, cash equivalents and short-term investments,including US$340.2 million held by our VIEs and the subsidiaries of VIEs. The remaining cashand short-term investments balance of US$1,469.9 million was held by our entities outsideChina.

The increase in our cash, cash equivalents and short-term investments as of December 31, 2020compared to that of December 31, 2019, was primarily due to US$741.6 million in cashprovided by operating activities, net proceeds from the issuance of 2030 Notes of US$740.3million and proceeds from the disposal of and refund from investments of US$289.6 million,partially offset by net cash paid to investments of US$392.5 million, net loans to SINA ofUS$292.1 million, and net cash paid for acquisitions of US$214.3 million. As of December 31,2020, our consolidated entities within China held US$1,663.4 million of cash, cash equivalentsand short-term investments, including US$445.2 million held by our VIEs and the subsidiariesof VIEs. The remaining cash and short-term investments balance of US$1,833.5 million washeld by our entities outside China.

The increase in our cash, cash equivalents and short-term investments as of December 31, 2019compared to that of December 31, 2018, was primarily due to US$631.7 million in cashprovided by operating activities and net proceeds from the issuance of 2024 Notes of US$793.3million, partially offset by cash paid to investees of US$688.9 million and net loans to SINAof US$190.3 million. Of the US$2,404.2 million in cash, cash equivalents and short-terminvestments as of December 31, 2019, our consolidated entities within China held US$952.0million, including US$99.5 million held by our VIEs and subsidiaries of VIEs. The remainingcash and short-term investments balance of US$1,452.2 million was held by our entitiesoutside China.

Our accounts receivable primarily include amounts due in one year or less from advertisingcustomers. Our accounts receivable turnover days, which are the average accounts receivablebalances as of the beginning and the end of the period divided by total revenues during theperiod and multiplied by the number of days during the period, were 56 days in 2018, 81 daysin 2019, 97 days in 2020, and 98 days for the six months ended June 30, 2021. As of August31, 2021, US$116.1 million, or 17%, of the total accounts receivable as of June 30, 2021 hadbeen settled.

We believe that our current cash, cash equivalents and short-term investments balance issufficient to fund our operating activities, capital expenditures and other obligations for at leastthe next twelve months. However, we may decide to enhance our liquidity position or increaseour cash reserve for future expansions and acquisitions through additional capital and/orfinance funding. The issuance and sale of additional equity would result in further dilution toour shareholders. The incurrence of indebtedness would result in increased fixed obligationsand could result in operating covenants that would restrict our operations. We cannot assureyou that financing will be available in amounts or on terms acceptable to us, if at all.

In utilizing the cash that we hold offshore, we may (i) make additional capital contributions toour PRC subsidiaries, (ii) establish new PRC subsidiaries and make capital contributions tothese new PRC subsidiaries, (iii) make loans to our PRC subsidiaries, or (iv) acquire/invest inoffshore entities with business operations in China in offshore transactions. However, most ofthese uses are subject to PRC regulations and/or approvals. For example, loans by us to ourPRC subsidiaries, which are foreign-invested enterprises, to finance their activities cannotexceed statutory limits and must be registered with SAFE or its local branches. See“Regulatory Overview — Regulations on Foreign Exchange.”

Substantially all of our future revenues are likely to continue to be in the form of RMB. Underexisting PRC foreign exchange regulations, payments of current account items, including profitdistributions, interest payments and trade and service-related foreign exchange transactions,can be made in foreign currencies without prior SAFE approval as long as certain routineprocedural requirements are fulfilled. Therefore, our PRC subsidiaries are allowed to paydividends in foreign currencies to us without prior SAFE approval by following certain routineprocedural requirements. However, approval from or registration with competent governmentauthorities is required where the RMB is to be converted into foreign currency and remitted outof China to pay capital expenses such as the repayment of loans denominated in foreigncurrencies. The PRC government may at its discretion restrict access to foreign currencies forcurrent account transactions in the future. See “Risk Factors — Risks Relating to DoingBusiness in the People’s Republic of China — Restrictions on the remittance of RMB into andout of China and governmental control of currency conversion may limit our ability to paydividends and other obligations, and affect the value of your investment.”

HOLDING COMPANY STRUCTURE

Weibo Corporation is a holding company that conducts its operations primarily through WeiboTechnology, our VIEs and their subsidiaries, all of which are incorporated in China. As a result,our ability to pay dividends depends upon dividends paid to us by Weibo Technology, our PRCsubsidiary. If Weibo Technology or any newly formed subsidiaries of our company incur debton their own behalf in the future, the instruments governing their debt may restrict their abilityto pay dividends to us. In addition, Weibo Technology is permitted to pay dividends to us onlyout of its retained earnings, if any, as determined in accordance with PRC accounting standardsand regulations. Under the PRC law, each of our PRC subsidiaries, our VIEs and theirsubsidiaries is required to set aside at least 10% of its after-tax profits each year, if any, to fundcertain statutory reserve funds until such reserve funds reach 50% of its registered capital. Inaddition, each of our PRC subsidiaries, our VIEs and their subsidiaries may allocate a portionof its after-tax profits based on PRC accounting standards to staff welfare and bonus funds, adiscretionary surplus fund and an enterprise expansion fund at its discretion or in accordancewith its articles of association. These reserve funds and staff welfare and bonus funds are notdistributable as cash dividends. As of December 31, 2020 and June 30, 2021, the amountrestricted, including paid-in capital, as determined in accordance with PRC accountingstandards and regulations, was US$451.7 million and US$450.3 million, respectively. AlthoughWeibo Technology has generated accumulated profits in 2020 and for the six months endedJune 30, 2021, it has not paid dividends in the past and currently has no intention to pay anydividend. We plan to reinvest most, if not all, of its profits, into our PRC operations for thefuture development and growth of our business.

INFLATION

In the past three years, inflation in China did not materially impact our results of operations.According to the National Bureau of Statistics of China, the consumer price index for 2018,2019 and 2020 increased by 2.1%, 2.9% and 2.5%, year over year, respectively. Although wehave not been materially affected by inflation in the past, we may be affected by inflation inthe future if the inflation rate in China increases.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Our discussion and analysis of our financial condition and results of operations are based uponour consolidated financial statements, which have been prepared in accordance with U.S.GAAP, appearing elsewhere in this document. The preparation of these consolidated financialstatements requires us to make estimates, judgments and assumptions that affect the reportedamounts of assets, liabilities, revenues and expenses, and related disclosure of contingentassets and liabilities. We evaluate these estimates, judgments and assumptions on an ongoingbasis.

Theseestimates form the basis for judgments we make about the carrying values of the assets andliabilities, which are not readily apparent from other sources. U.S. GAAP requires makingestimates and judgments in several areas, including, but not limited to, the basis ofconsolidation, revenue recognition, fair value accounting, income taxes, goodwill and otherlong-lived assets, allowances for credit losses, stock-based compensation, the estimated usefullives of assets, convertible debt, business combination, and foreign currency. We base theestimates and judgments on historical information and on various other assumptions that webelieve are reasonable under the circumstances. Actual results could differ materially fromsuch estimates.

Revenue Recognition

In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU 2014-09,“Revenue from Contracts with Customers (Topic 606).” We adopted the new revenue guidancesince January 1, 2018.

Under ASC 606, revenues are recognized when control of the promised goods or services istransferred to customers in an amount that reflects the consideration we expect to be entitledto in exchange for those goods or services. We identify the contracts with customers and allperformance obligations within those contracts. We then determine the transaction price andallocate the transaction price to the performance obligations within the contracts withcustomers, recognizing revenue when, or as, we satisfy our performance obligations.

We do not believe that significant management judgments are involved in revenue recognition,but the amount and timing of our revenues could be different for any period if managementmade different judgments. Certain customers may receive sales rebates, which are accountedfor as variable consideration. We estimate annual expected revenue volume of each individualagent with reference to their historical results. We recognize revenue for the amount of fees wereceive from our advertisers, after deducting estimated sales rebates and net of value-added tax(“VAT”) under ASC 606. We believe that there will not be significant changes to our estimatesof variable consideration.

FINANCIAL INFORMATION

We enter into contracts with our customers, which may give rise to contract assets (unbilledrevenue) or contract liabilities (deferred revenue). The payment terms and conditions withinthe contracts vary by the type and location of our customers and products or servicespurchased, the substantial majority of which are due in less than one year. Deferred revenuerelated to unsatisfied performance obligations at the end of the period mainly consists of theunamortized balance of customer advance of advertising and marketing services. The deferredrevenues are recognized based on customers’ consumption or amortized on a straight-line basisthrough the service period for different products/services. Due to the generally short-termduration of the contracts, the majority of the performance obligations are satisfied in thefollowing reporting period.

Practical Expedients and Exemptions. We generally expense sales commissions when incurredbecause the amortization period is generally one year or less. These costs are recorded withinsales and marketing expenses.

Advertising and Marketing Revenues. Advertising and marketing revenues are derivedprincipally from online advertising, including social display ads and promoted marketing.Social display ad arrangements allow customers to place advertisements on particular areas ofour platform or website in particular formats and over particular periods of time, which istypically no more than three months. We enter into cost per mille (“CPM”), or cost perthousand impressions, advertising arrangements with the customers, under which we recognizerevenues based on the number of times that the advertisement has been displayed. We also enterinto cost per day (“CPD”) advertising arrangements with customers, under which we recognizerevenues ratably over the contract periods. Promoted marketing arrangements are primarilypriced based on CPM. Under the CPM model, customers are obligated to pay when theadvertisement is displayed. Our majority revenue transactions are based on standard businessterms and conditions, which are recognized net of agency rebates. The agency rebates areaccounted for as variable consideration and are estimated during interim periods based onestimated annual revenue volume of each individual agent with reference to their historicalresults, which involves accounting judgment. We believe our estimation approach in variableconsideration results in revenue recognition in a manner consistent with the underlyingeconomics of the transaction.

Our contracts with customers may include multiple performance obligations, which primarilyconsist of combinations of services to allow customers to place advertisements on differentareas of our platform or website. For such arrangements, advertising arrangements involvingmultiple deliverables are broken down into single-element arrangements based on theirstand-alone selling price for revenue recognition purposes. The estimation of stand-aloneselling price involves significant judgment, especially for the deliverables that have not beensold separately. For those deliverables, we determine the best estimate of the stand-aloneselling price by taking into consideration the pricing of advertising areas of our platform orwebsite with similar popularities and advertisements with similar formats and quoted pricesfrom competitors and other market conditions. We believe our estimation approach instand-alone selling price and allocation of the transaction price on a relative stand-alone sellingprice to each performance obligation results in revenue recognition in a manner consistent withthe underlying economics of the transaction and the allocation principle included in ASC 606.Revenues recognized with reference to best estimation of selling price were immaterial for allperiods presented. Most of such contracts have all performance obligations completed withinone year. Changes in judgments on these assumptions and estimates could materially impactthe timing or amount of revenue recognition. Contracts with customers of online advertisingmay require cooperation from third parties. We pay a predetermined portion of revenues weearned from advertising contracts to the third parties such as key opinion leaders who

participate in advertising and promotion activities by monetizing their social assets. We havedetermined that we are the principal in these transactions, as we are primarily responsible forfulfilling all of the obligations related to advertising contracts. We have discretion inestablishing the pricing of the contracts and control the advertising inventory before thedelivery to customers. We record revenues derived from such contracts on a gross basis and theportion paid to the third parties is recognized as the cost of revenues.

Revenues from barter transactions are recognized during the period in which theadvertisements are displayed on our properties. Barter transactions in which physical goods orservices are received in exchange for advertising services are recorded based on the fair valuesof the goods or services received.

Value-added Services Revenues. We generate value-added services revenues principally fromfee-based services, mainly including VIP membership, live streaming, and game-relatedservices. Revenues from these services are recognized when control of the promised servicesis transferred to customers, in an amount that reflects the consideration we expect to be entitledto in exchange for those services.

VIP membership mainly includes a service package consisting of one performance obligationof providing user certification and preferential benefits, such as daily priority listings andhigher quota for following user accounts. Prepaid VIP membership fees are recorded asdeferred revenue and recognized as revenue ratably over the contract period of the membershipservice.

Live streaming generates revenue from sales of virtual items on the Yizhibo platform. Userscan access the platform and view the live streaming content and interact with the broadcastersfor free. We design, create and offer various virtual items for sales to users with pre-determinedselling price. Each virtual item is considered as a distinctive performance obligation. Salesproceeds are recorded as deferred revenue and recognized as revenue based on the consumptionof the virtual items. Users can purchase and present virtual items to broadcasters to showsupport for their favorite ones. Under the arrangements with broadcasters or broadcasteragencies, we share with them a portion of the revenues derived from the consumption of virtualitems. Revenues derived from the sale of virtual items are recorded on a gross basis as we havedetermined that we act as the principal to fulfill all obligations related to the live streamingservices. The portion paid to broadcasters and/or broadcaster agencies is recognized as the costof revenues. We do not have further obligations to the user after the virtual items are consumed.

Game-related revenues are mostly generated from the purchase of virtual items by gameplayers through our platform, including items, avatars, skills, privileges or other in-gameconsumables, features or functionality, within the games. Our performance obligation is toprovide ongoing game services to players who purchased virtual items to gain an enhancedgame-playing experience. Each virtual item is considered as a distinctive performanceobligation. We collect payments from the game players in connection with the sale of virtualcurrency, which can be used to purchase virtual items in online games.

For games co-operated with third party developers, revenue is recorded on a gross basis forgames for which we are acting as the principal in fulfilling all obligations related to the games,and revenue is recorded net of predetermined revenue sharing with the game developers forgames for which we are not acting as the principal in fulfilling all obligations.

Sales of virtual currencies are recognized as revenues over the estimated lifespans of in-gamevirtual items. The estimated lifespans of different virtual items are determined by themanagement based on either the expected user relationship periods or the stipulated period ofvalidity of the relevant virtual items depending on the respective term of virtual items. Virtualcurrency sold for game-related services in excess of recognized revenues is recorded asdeferred revenues.

Stock-based compensation

All stock-based awards to employees and directors, such as stock options and restricted shareunits (“RSUs”), are measured at the grant date based on the fair value of the awards.Stock-based compensation, net of forfeitures, is recognized as expenses on a straight-line basisover the requisite service period, which is the vesting period.

We use the Black-Scholes option pricing model to estimate the fair value of stock options. Thedetermination of estimated fair value of stock-based payment awards on the grant date usingan option pricing model is affected by the fair value of our ordinary shares as well asassumptions regarding a number of complex and subjective variables. These variables includethe expected value volatility of us over the expected term of the awards, actual and projectedemployee stock option exercise behaviors, a risk-free interest rate and expected dividends, ifany. Options granted generally vest over four years.

We recognize the estimated compensation cost of restricted share units based on the fair valueof the corresponding ordinary shares on the date of the grant. We recognize the compensationcost, net of estimated forfeitures, over a vesting term of generally four years for service-basedrestricted share units. We also recognize the compensation cost of performance-based restrictedshare units, net of estimated forfeitures, if it is probable that the performance condition will beachieved at the end of each reporting period.

Forfeitures are estimated at the time of grant and revised in subsequent periods if actualforfeitures differ from those estimates. We use historical data to estimate the pre-vesting optionand record stock-based compensation expense only for those awards that are expected to vest.

Taxation

Income Taxes. Income taxes are accounted for using the asset and liability approach. Under thisapproach, income tax expense is recognized for the amount of taxes payable or refundable forthe current year. In addition, deferred tax assets and liabilities are recognized for the expectedfuture tax consequences of temporary differences between the financial reporting and tax basesof assets and liabilities and for operating losses and tax credit carry forwards. We record avaluation allowance to reduce deferred tax assets to an amount for which realization is morelikely than not.

Uncertain Tax Positions. To assess uncertain tax positions, we apply a more likely than notthreshold and a two-step approach for the tax position measurement and financial statementrecognition. Under the two-step approach, the first step is to evaluate the tax position forrecognition by determining if the weight of available evidence indicates that it is more likelythan not that the position will be sustained, including the resolution of related appeals orlitigation processes, if any. The second step is to measure the tax benefit as the largest amountthat is more than 50% likely of being realized upon settlement.

Credit Losses

In 2016, the FASB issued ASC Topic 326, which amends previously issued guidance regardingthe impairment of financial instruments by creating an impairment model that is based onexpected losses. The guidance is applicable to accounts receivable and was adopted on January1, 2020. Accounts receivable are recorded at the original amount less an allowance for anypotential uncollectible amounts. The management makes estimates of expected credit andcollectability trends for the allowance for credit losses based upon the assessment of variousfactors, including historical experience, the age of the accounts receivable balances, credit-worthiness of the customers, current economic conditions, reasonable and supportableforecasts of future economic conditions, and other factors that may affect its ability to collectfrom the customers. We also provide specific provisions for allowance when facts andcircumstances indicate that the receivable is unlikely to be collected. Expected credit losses arerecorded as general and administrative expenses on the consolidated statements ofcomprehensive income.

ASC Topic 326 is also applicable to the loans to and interest receivable from other relatedparties included in the prepaid expenses and other current assets on the consolidated balancesheets. Our management estimates the allowance for credit losses on loans and interestreceivable not sharing similar risk characteristics on an individual basis, based on lifetimeexpected credit losses of these loans and interest receivable by estimating the loan collectionschedule, then discounting these cash flows to their present values. The key factors consideredwhen determining the above allowances for credit losses include the estimated loan collectionschedule, discount rate, financial condition and performance data of the borrowers andreasonable and supportable performance forecasts.

Fair Value Measurements

Financial instruments

All financial assets and liabilities are recognized or disclosed at fair value in the consolidatedfinancial statements on a recurring basis. Accounting guidance defines fair value as the pricethat would be received from selling an asset or paid to transfer a liability in an orderlytransaction between market participants at the measurement date. When determining the fairvalue measurements for assets and liabilities required or permitted to be recorded at fair value,we consider the principal or most advantageous market in which we would transact and weconsider assumptions that market participants would use when pricing the asset or liability.

We measure the equity method investments at fair value on a non-recurring basis only if animpairment charge were to be recognized. For those investments without readily determinablefair value, we measure them at fair value when observable price changes are identified or animpairment charge is recognized. The fair values of our privately held investments as disclosedare determined based on the discounted cash flow model using the discount curve of marketinterest rates or based on the similar transaction price in the market directly. The fair valuesof our long-term investments in the equity securities of publicly listed companies are measuredusing quoted market prices. Our non-financial assets, such as intangible assets, goodwill, fixedassets and operating lease assets, would be measured at fair value only if they were determinedto be impaired.

Accounting guidance establishes a fair value hierarchy that requires an entity to maximize theuse of observable inputs and minimize the use of unobservable inputs when measuring fairvalue. A financial instrument’s categorization within the fair value hierarchy is based upon thelowest level of input that is significant to the fair value measurement. Accounting guidanceestablishes three levels of inputs that may be used to measure fair value:

• Level 1 applies to assets or liabilities for which there are quoted prices in active marketsfor identical assets or liabilities.

• Level 2 applies to assets or liabilities for which there are inputs other than quoted pricesincluded within Level 1 that are observable for the asset or liability such as quoted pricesfor similar assets or liabilities in active markets; quoted prices for identical asset orliabilities in markets with insufficient volume or infrequent transactions (less activemarkets); or model-derived valuations in which significant inputs are observable or canbe derived principally from, or corroborated by, observable market data.

• Level 3 applies to assets or liabilities for which there are unobservable inputs to thevaluation methodology that are significant to the measurement of the fair value of theassets or liabilities.

The carrying amount of cash and cash equivalents, short-term investments, accounts receivabledue from third parties, accounts receivable due from Alibaba, accounts receivable due fromother related parties, accounts payable, amount due from/to SINA, and accrued and otherliabilities approximates fair value because of their short-term nature.

• Equity investments accounted for using the measurement alternative

For investments without readily determinable fair values, we elect to record these investmentsat cost, less impairment, and plus or minus subsequent adjustments for observable pricechanges. Under this measurement alternative, changes in the carrying value of the investmentswill be recognized in consolidated statement of comprehensive income, whenever there areobservable price changes in orderly transactions for the identical or similar investment of thesame issuer. Impairment charges will be recorded when any impairment indicators are notedand the fair value is lower than the carrying value. Our investments made during the TrackRecord Period, mainly included an investment of US$72.7 million in an investee ine-commerce business and an investment of US$21.8 million in a company engaged in creatingand providing unique online cartoon content in 2018, a follow-on investment of US$100.0million in Yixia Tech in 2019, an investment of US$46.8 million in a financing guaranteecompany and an investment of US$30.6 million in a commercial search business in 2020, aswell as a further investment of US$39.5 million in a leading mobile photo and videoapplication in China.

• Equity investments accounted for using equity method

Investments in entities in which we can exercise significant influence and hold an investmentin voting common shares or in-substance common shares (or both) of the investee but in whichwe do not own a majority equity interest or control are accounted for using the equity methodof accounting in accordance with ASC topic 323 (“ASC 323”), Investment – Equity Methodand Joint Ventures. Our investments made during the Track Record Period mainly includedUS$93.0 million investments in two funds in 2018, a US$57.4 million investment in a companyproviding consumer finance services in 2019, several investment funds in 2020 and anadditional investment of US$60.0 million in an investment fund for the six months ended June30, 2021.

• Equity securities with readily determinable fair value

The marketable equity securities were reclassified as investments with readily determinablefair values under ASU 2016-01. Investments in marketable equity securities are valued usingthe market approach based on the quoted prices in active markets at the reporting dates. Weclassify the valuation techniques that use these inputs as Level 1 of fair value measurements.In December 2019, one of the Group’s investees, Beijing Showworld Technology Co., Ltd., acompany providing social and new media marketing services, completed its listing on ShanghaiStock Exchange through an equity reconstruction with a then-listed company. BeforeShowworld’s IPO, the Group accounted for the investment under equity securities withoutreadily determinable fair values and then reclassified it to investments with readilydeterminable fair values the moment it went public. The Group recorded US$2.8 million fairvalue change loss, US$171.6 million fair value change gain, US$37.6 million fair value changegain, US$120.3 million fair value change loss and US$42.7 million fair value change loss,which was unrealized, for the years ended December 31, 2018, 2019, 2020 and six monthsended June 30, 2020 and 2021, respectively.

Pursuant to ASC 321, for equity investments measured at fair value with changes in fair valuerecorded in earnings, we do not assess whether those securities are impaired. At each reportingdate, we make a qualitative assessment of whether the investment is impaired, applyingjudgement in considering various factors and events. If a qualitative assessment indicates thatthe investment is impaired, we estimate the investment’s fair value in accordance with theprinciples of ASC 820. If the fair value is less than the investment’s carrying value, we

recognize an impairment loss in net income equal to the difference between the carrying valueand fair value. We recognized US$23.6 million, US$230.9 million, US$126.8 million, US$2.5million and US$66.6 million impairment charges to investments without readily determinablefair values for the years ended December 31, 2018, 2019, 2020 and six months ended June 30,2020 and 2021 respectively.

Our main investment strategy is to expand and strengthen our ecosystem to further diversifyour monetization channels. Long-term investments are comprised of investments in publiclytraded companies, privately held companies, and limited partnerships.

Our major investments during the Track Record Period included Beijing ShowworldTechnology Co., Ltd., providing social and new-media marketing services, Xiaoju KuaizhiInc., a mobile transport platform that operates Didi, Yixia Tech Co., Ltd., a developer of mobilevideo apps, Shanghai Benqu Network Technology Co., Ltd, a developer of Wuta beauty cameraapp, and other investees that complement our ecosystem.

Leases

In February 2016, the FASB issued a new standard on leases, ASU 2016-02, “Leases (Topic842)”, which requires a lessee to recognize assets and liabilities arising from operating leases.A lessee should recognize a liability to make lease payments (the Lease Liability) and aright-of-use asset (the Operating Lease Assets) representing its right to use the underlying assetfor the lease term. For leases with a term of twelve months or less, a lessee is permitted to makean accounting policy choice not to recognize lease assets and lease liabilities. In July 2018, theFASB issued an amendment, ASU 2018-11, which provides another transition method inaddition to the existing transition methods by allowing entities to initially apply the new leasesstandard at the effective date and recognize a cumulative-effect adjustment to the openingbalance of retained earnings in the period of adoption and to not retrospectively adjust priorperiods’ financial statements.

FINANCIAL INFORMATION

– 259 –

On January 1, 2019, we have adopted the new lease standard using the transition method byapplying the standard to all leases existing at the date of initial application. We chose to notrecognize lease assets and lease liabilities for leases with a term of twelve months or less, tonot separate non-lease components from lease components, and to not reassess leaseclassification, treatment of initial direct costs, or whether an existing or expired contractcontains a lease according to the practical expedients permitted under the transition method.We did not retrospectively adjust the prior comparative periods. Under the new lease standard,we determine if an arrangement is or contains a lease at inception. Right-of-use assets andliabilities are recognized at the lease commencement date based on the present value ofremaining lease payments over the lease terms. We consider only payments that are fixed anddeterminable at the time of lease commencement.

Long-Lived Assets

Property and equipment

Property and equipment are stated at cost less accumulated depreciation, amortization andimpairment, if any. Depreciation is computed using the straight-line method over the estimateduseful lives of the assets, generally from three to four years for computers and equipment andfive years for furniture and fixtures. Leasehold improvements are amortized over the shorterof the estimated useful lives of the assets or the remaining lease term.

Goodwill

Goodwill represents the excess of the purchase price over the fair value of the identifiableassets and liabilities acquired as a result of our acquisitions of interests in our subsidiaries andconsolidated VIE. We assess goodwill for impairment in accordance with ASC Subtopic 350-20(“ASC 350-20”), Intangibles — Goodwill and Other: Goodwill, which requires that goodwillbe tested for impairment at the reporting unit level at least annually and more frequently uponthe occurrence of certain events, as defined by ASC 350-20. U.S. The guidance provides theoption that we may first assess qualitative factors to determine whether it is necessary toperform the quantitative goodwill impairment test, by taking into considerationmacroeconomics, overall financial performance, industry and market conditions and our shareprice. If determined to be necessary, the quantitative impairment test shall be used to identifygoodwill impairment and measure the amount of a goodwill impairment loss to be recognized(if any). Application of a goodwill impairment test requires significant management judgment,including the identification of reporting units, assigning assets and liabilities to reporting units,assigning goodwill to reporting units, and determining the fair value of each reporting unit.Judgment in estimating the fair value of reporting units includes estimating future cash flows,determining appropriate discount rates and making other assumptions. Changes in theseestimates and assumptions could materially affect the determination of fair value for eachreporting unit. During 2018, impairment indicators were identified by us for the game relatedreporting unit including adversely policy change on game industry and failure to meetforecasted financial performance supporting the goodwill without prospect of future recovery.We fully impaired the goodwill arising from acquisition of several game business amountingUS$10.6 million as we expect it would be hard for the game business to recover. For the yearsended December 31, 2019 and 2020 and six months ended June 30, 2020 and 2021, noimpairment indicator was noted by performing qualitative analysis, therefore, no provision wasrecorded.

FINANCIAL INFORMATION

– 260 –

Intangible assets other than goodwill

Intangible assets arising from acquisitions are recognized at fair value upon acquisition andamortized on a straight-line basis over their estimated useful lives, generally from three to tenyears. Long-lived assets and certain identifiable intangible assets other than goodwill to beheld and used are reviewed for impairment whenever events or changes in circumstancesindicate that the carrying amount of such assets may not be recoverable. Determination ofrecoverability is based on an estimate of undiscounted future cash flows resulting from the useof the asset and its eventual disposition. Measurement of any impairment loss for long-livedassets and certain identifiable intangible assets that management expects to hold or use is basedon the amount by which the carrying value exceeds the fair value of the asset. Judgment is usedin estimating future cash flows, determining appropriate discount rates and making otherassumptions. Changes in these estimates and assumptions could materially affect thedetermination of the asset’s fair value.

Convertible debt and unsecured senior notes

We determine the appropriate accounting treatment of our convertible debt in accordance withthe terms in relation to the conversion feature. After considering the impact of such features,we may account for such instrument as a liability in its entirety, or separate the instrument intodebt and equity components following the respective guidance described under ASC 815Derivatives and Hedging and ASC 470 Debt.

The debt discount, if any, together with related issuance cost are subsequently amortized asinterest expense over the contractual life. We presented the issuance costs of debt as a directdeduction from the related debt during the periods presented.

The unsecured senior notes are recognized initially at fair value, net of debt discounts orpremiums, if any, issuance costs and other incidental fees, all of which are recorded as a directdeduction of the proceeds received from issuing the unsecured senior notes, and the relatedaccretion is recorded as interest expense in the consolidated statement of comprehensiveincome over the estimated term using the effective interest method.

RELATED PARTY TRANSACTIONS

For details relating to our related party transactions, see “Related Party Transactions” and Note10 to the Accountant’s Report set out in Appendix IA to this document. Our Directors believethat our transactions with related parties during the Track Record Period were conducted on anarm’s length basis, and they did not distort our results of operations or make our historicalresults not reflective of our future performance.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Foreign Exchange Risk

The value of the RMB against the U.S. dollar and other currencies is affected by changes inChina’s political and economic conditions and China’s foreign exchange policies, among otherthings. It is difficult to predict how market forces or PRC or U.S. government policy mayimpact the exchange rate between the RMB and the U.S. dollar in the future. To date, we havenot entered into any hedging transactions in an effort to reduce our exposure to foreigncurrency exchange risk.

Our revenues and costs are mostly denominated in RMB, and a significant portion of ourfinancial assets are also denominated in RMB, whereas our reporting currency is the U.S.dollar. Any significant depreciation of the RMB may materially and adversely affect ourrevenues, earnings and financial position as reported in U.S. dollars. To the extent that we needto convert U.S. dollars we received from the issuance of 2022 Notes, 2024 Notes and 2030Notes into RMB for our operations, appreciation of the RMB against the U.S. dollar wouldhave an adverse effect on the RMB amount we would receive from the conversion. Conversely,if we decide to convert our RMB into U.S. dollars for the purpose of making payments fordividends on our ordinary shares or ADSs or for other business purposes, appreciation of theU.S. dollar against the RMB would have a negative effect on the U.S. dollar amount availableto us.

Below is a sensitivity analysis on the impact of a change in the value of the RMB against theU.S. dollar assuming: (1) projected net income from operation in China equal to the net incomeof 2020, (2) projected net assets of the operation in China equal to the balances in RMB andU.S. dollar as of December 31, 2020 and (3) currency fluctuation occurring proportionatelyover the period:

Interest Rate Risk

Our exposure to interest rate risk primarily relates to the interest income generated by excesscash, which is mostly held in interest-bearing bank deposits. Interest-earning instruments carrya degree of interest rate risk. We have not been exposed to material risks due to changes ininterest rates, and we have not used any derivative financial instruments to manage our interestrisk exposure. However, our future interest income may fall short of expectations due tochanges in market interest rates.

Investment Risk

As of December 31, 2020 and June 30, 2021, our equity investments totaled US$1,179.5million and US$1,123.3 million, respectively. We adopted ASU 2016-01, “Classification andMeasurement of Financial Instruments,” beginning January 1, 2018. After the adoption of ASU2016-01, we measure investments in equity securities other than equity method investments atfair value through earnings. For those investments without readily determinable fair values, weelected to record these investments at cost, less impairment, and plus or minus subsequentadjustments for observable price changes (referred to as the measurement alternative). Changesin the basis of these investments are reported in current earnings. We recognized gain ofUS$35.1 million in upward adjustment and loss of US$69.5 million in downward adjustmentfor fair value changes on investments for the year ended December 31, 2020 and for the sixmonths ended June 30, 2021, respectively.

Our investments other than equity method are subject to a wide variety of market related risksthat could substantially reduce or increase the fair value of our holdings. Investments usingmeasurement alternative are investments in privately held companies. Valuations of ourinvestments in private companies are inherently more complex due to the lack of readilyavailable market data. The fair value is measured at the time of the observable transaction,which is not necessarily an indication of the current fair value as of the balance sheet date.These investments, especially those in the early stages, are inherently risky because thetechnologies or products these companies have under development are typically in the earlyphases and may never materialize and they may experience deterioration in financial condition,which could result in a loss of a substantial part of our investment in these companies. Thesuccess of our investment in any private company is also dependent on the likelihood of ourability to realize value in our investments through liquidity events such as public offerings,acquisitions, private sales or other favorable market events reflecting appreciation to the costof our initial investment. Volatility in the global economic climate and financial markets couldalso result in a significant impairment charge on our non-marketable equity securities. As ofDecember 31, 2020 and June 30, 2021, the carrying value of our investments usingmeasurement alternative was US$579.1 million and US$453.5 million, respectively.

The carrying values of our equity method investments generally do not fluctuate due to marketprice changes, however these investments could be impaired if the carrying value exceeds thefair value.

We periodically review our investments for impairment. Factors we consider to make suchdetermination include the duration and severity of the impairment, the reason for the declinein value, the potential recovery period, and our intent to sell, or whether it is more likely thannot that we will be required to sell, the investment before recovery. We recorded US$212.0million and US$66.6 million of investment related impairment charges for the year endedDecember 31, 2020 and for the six months ended June 30, 2021, respectively. We are unableto control these factors and an impairment charge recognized by us will unfavorably impact ouroperating results and financial position.

FINANCIAL INFORMATION

– 267 –

Our short-term investments as of December 31, 2020 and June 30, 2021 totaled US$1,682.0million and US$930.8 million, respectively, which were composed of bank time deposits andwealth management products with maturity over three months but within one year.

DIVIDEND POLICY

We have not previously declared or paid cash dividends and we have no plan to declare or payany dividends in the near future on our shares or ADSs. We currently intend to retain most, ifnot all, of our available funds and any future earnings to fund the development and growth ofour business.

We are a holding company incorporated in the Cayman Islands. We rely principally ondividends from our PRC subsidiaries for our cash requirements, including any payment ofdividends to our shareholders. PRC regulations may restrict the ability of our PRC subsidiariesto pay dividends to us. See “Risk Factors — Risks Relating to Doing Business in the People’sRepublic of China — Any limitation on the ability of our PRC subsidiaries to make paymentsto us, or the tax implications of making payments to us, could have a material adverse effecton our ability to conduct our business or our financial condition.”

Our board of directors has discretion as to whether to distribute dividends, subject to applicablelaws. In addition, our shareholders may by ordinary resolution declare dividends, but nodividend may exceed the amount recommended by our directors. Under Cayman Islands law,our company may pay dividends only out of either profit or share premium account, providedthat in no circumstances may a dividend be paid if this would result in our company beingunable to pay its debts as they fall due in the ordinary course of business. Even if our boardof directors decides to pay dividends, the form, frequency and amount will depend upon ourfuture operations and earnings, capital requirements and surplus, general financial condition,contractual restrictions and other factors that the board of directors may deem relevant. If wepay any dividends, our depositary will distribute such dividends to our ADS holders to thesame extent as holders of our ordinary shares, subject to the terms of the deposit agreement,including the fees and expenses payable thereunder. Cash dividends on our ordinary shares, ifany, will be paid in U.S. dollars.

NO MATERIAL ADVERSE CHANGE

After due and careful consideration, our directors confirm that, up to the date of this document,there has not been any material adverse change in our financial or trading position or prospectssince June 30, 2021, and there is no event since June 30, 2021 which would materially affectthe information shown in the Accountant’s Report in Appendix IA to this document.

LISTING EXPENSES

We expect to incur listing expenses of approximately HK$129.7 million, accounting for 6.08%of gross proceeds, after June 30, 2021, including underwriting-related expenses ofapproximately HK$27.1 million, and non-underwriting related expenses of approximatelyHK$102.6 million which consist of fees and expenses for legal advisors and accountants ofapproximately HK$68.1 million and other fees and expenses of approximately HK$34.5million (assuming that the Global Offering is conducted at the indicative offer price per OfferShare of HK$388.00 for both Hong Kong Public Offering and International Offering and theOver-allotment Option is not exercised). We expect approximately HK$121.8 million of thelisting expenses will be recorded as a deduction in equity directly and approximately HK$7.9million of the listing expenses will be charged to the profit or loss of our Company. The SellingShareholder pays the underwriting fees, the Hong Kong Stock Exchange trading fee, SFCtransaction levy and SEC registration fee corresponding to the Sale Shares, and we bear otherlisting expenses.

INDEPENDENCE FROM CONTROLLING SHAREHOLDERS

Having considered the following factors, our directors are satisfied that we are capable ofcarrying on our business independently of our controlling shareholders and their closeassociates after the Listing.

Management independence

Our business is managed and conducted by our board and senior management. Our boardconsists of seven directors, of whom three are independent directors unrelated to ourcontrolling shareholders. For more information, please see “Directors and SeniorManagement”.

Our directors consider that our board and senior management will function independently ofour controlling shareholders because:

(a) each director is aware of his/her fiduciary duties as a director, which require, among otherthings, that he/she acts for the benefit, and in the interests, of our Company and does notallow any conflict between his/her duties as a director and his/her personal interests;

(b) our daily management and operations are carried out by our senior management, all ofwhom have substantial experience in our Group’s business and/or the industry in whichwe operate, and will be able to make decisions that are in our best interest;

(c) we have three independent directors and certain matters of our Company will always bereferred to them for review and/or approval;

(d) in the event that there is a potential conflict of interest arising out of any transaction tobe entered into between our Group and our directors or their respective associates, theinterested director(s) is required to declare the nature of his/her interest before voting atthe relevant meeting(s) in respect of that transaction; and

(e) we have adopted a series of corporate governance measures to manage conflicts ofinterest, if any, between our Group and our controlling shareholders that would supportour independent management; see “— Corporate Governance Measures”.

Operational independence

We have certain ongoing transactions with SINA. For details, please refer to the section“Related Party Transactions — Our Relationship with SINA” and “Related Party Transactions— Transactions with SINA”. Our Group (through our subsidiaries) holds all material licensesand owns all relevant intellectual properties and research and development facilities necessaryto carry on our business. We have sufficient capital, facilities, equipment and employees tooperate our business independently of our controlling shareholders. Our access to, andrelationship with, our customers and suppliers are independent of our controlling shareholders,and we have an independent management team that operates our business.

Financial Independence

We have independent internal control and accounting systems. We also have an independentfinance department responsible for discharging the treasury function, and an audit committeecomprising solely of independent directors to oversee our accounting and financial reportingprocesses. We are capable of obtaining financing from third parties, if necessary, withoutreliance on our controlling shareholders.

Save for those disclosed in the section “Related Party Transactions — Our Relationship withSINA” and “Related Party Transactions — Transactions with SINA”, there are no other loansor guarantees granted to our controlling shareholders or their respective associates, and thereare no loans or guarantees provided by our controlling shareholders or their respectivelyassociates, as of the Latest Practicable Date.

Following such a declaration beingmade, subject to any separate requirement for audit committee approval under applicable lawor the Listing Rules of the Nasdaq, and unless disqualified by the chairman of the relevantboard meeting, a director may vote in respect of any contract or proposed contract orarrangement in which such director is interested and may be counted in the quorum at suchmeeting.

According to the Catalogue of Telecommunications Business,most recently updated in June 6, 2019, the “value-added telecommunication services” wasfurther classified into two sub-categories and 10 items.

According to these measures, commercial internet content provision serviceoperators must obtain an Internet Content Provision License from the relevant governmentauthorities before engaging in any commercial internet content provision operations within thePRC. These measures further stipulate that entities providing internet content provisionservices regarding news, publishing, education, medicine, health, pharmaceuticals and medicalequipment must procure the approval of the national government authorities responsible forsuch areas prior to applying for an operating license from the relevant government authorities.

The Administrative Measures on Telecommunications Business Operating Licenses, (《電信業務經營許可管理辦法》) promulgated by the MIIT in 2001 and revised in 2009 and 2017, setforth the types of licenses required to operate value-added telecommunications services and thequalifications and procedures for obtaining such licenses. For example, an information serviceoperator providing value-added telecommunication services in multiple provinces is requiredto obtain an inter-regional license, whereas an information services operator providing thesame services in one province is required to obtain a local license.

To comply with these PRC laws and regulations, Weimeng holds an Internet Content ProvisionLicense issued by the Beijing Telecommunications Administration.

REGULATIONS ON INTELLECTUAL PROPERTY RIGHTS

China has adopted legislation governing intellectual property rights, including trademarks,patents and copyrights. China is a signatory to the major international conventions onintellectual property rights and became a member of the Agreement on Trade Related Aspectsof Intellectual Property Rights upon its accession to the World Trade Organization in December2001.

Patent. The Patent Law (《中華人民共和國專利法》) was adopted in 1984 and amended in1992, 2000, 2008 and 2020. The amended version in 2020 came into effect on June 1, 2021.The purpose of the Patent Law is to protect lawful interests of patent holders, encourageinvention, foster applications of invention, enhance innovative capabilities and promote thedevelopment of science and technology. To be patentable, invention or utility models mustmeet three conditions: novelty, inventiveness and practical applicability. Patents cannot begranted for scientific discoveries, rules and methods for intellectual activities, methods used todiagnose or treat diseases, animal and plant breeds, nuclear transformation method andsubstances obtained by the method of nuclear transformation or a design which has majormarking effect on the patterns or colors of graphic print products or a combination of bothpatterns and colors. The Patent Office under the State Intellectual Property Office isresponsible for receiving, examining and approving patent applications. A patent is valid for aterm of twenty years in the case of an invention and a term of ten years in the case of utilitymodels and a term of fifteen years in the case of designs. A third-party user must obtain consentor a proper license from the patent owner to use the patent. Otherwise, the use constitutes aninfringement of patent rights.

We have registered 193 patents and applied for 218 patents with the PRC State IntellectualProperty Office as of June 30, 2021.

Copyright. The Copyright Law (《中華人民共和國著作權法》) was adopted in 1990 andamended in 2001, 2010 and 2020. The amended version in 2020 came into effect on June 1,2021. The amended Copyright Law extends copyright protection to internet activities, productsdisseminated over the internet and software products. In addition, there is a voluntaryregistration system administered by the China Copyright Protection Center. The amendedCopyright Law also requires registration of a copyright pledge.

According to the Copyright Law, an infringer will be subject to various civil liabilities, whichinclude stopping the infringement, eliminating the damages, apologizing to the copyrightowners and compensating the losses of copyright owners. The Copyright Law further providesthat the infringer must compensate the actual loss suffered by the copyright owner. If the actualloss of the copyright owner is difficult to calculate, the illegal income received by the infringeras a result of the infringement will be deemed as the actual loss or if such illegal income is alsodifficult to calculate, the court can decide the amount of the actual loss up to RMB5,000,000.

To address the problem of copyright infringement related to the content posted or transmittedover the internet, the National Copyright Administration and the MIIT jointly promulgated theMeasures for Administrative Protection of Copyright Related to the Internet (《互聯網著作權行政保護辦法》) in 2005.

The Protection of the Right of Communication through Information Networks (《信息網絡傳播權保護條例》) was promulgated by the State Council in 2006 and amended in 2013. Underthis regulation, with respect to any information storage space, search or link services providedby an internet service provider, if the legitimate right owner believes that the works,performance or audio or video recordings pertaining to that service infringe his or her rights

of communication, the right owner may give the internet service provider a written noticecontaining the relevant information along with preliminary materials proving that aninfringement has occurred, and requesting that the internet service provider delete, ordisconnect the links to, such works or recordings. The right owner will be responsible for thetruthfulness of the content of the notice. Upon receipt of the notice, the internet serviceprovider must delete or disconnect the links to the infringing content immediately and forwardthe notice to the user that provided the infringing works or recordings. If the written noticecannot be sent to the user due to the unknown IP address, the contents of the notice shall bepublicized via information networks. If the user believes that the subject works or recordingshave not infringed others’ rights, the user may submit to the internet service provider a writtenexplanation with preliminary materials proving non-infringement, and a request for therestoration of the deleted works or recordings. The internet service provider should thenimmediately restore the deleted or disconnected content and forward the user’s writtenstatement to the right owner.

Under the Civil Code of the PRC (《中華人民共和國民法典》) effective from January 1, 2021,both internet users and internet service providers may be liable for the wrongful acts of userswho infringe the lawful rights of other parties. If an internet user utilizes internet services tocommit a tortious act, the party whose rights are infringed may request the internet serviceprovider to take measures, such as removing or blocking the content, or disabling the linksthereto, to prevent or stop the infringement. If the internet service provider does not takenecessary measures after receiving such notice, it shall be jointly liable for any further damagessuffered by the rights holder. Furthermore, if an internet service provider fails to take necessarymeasures when it knows that an internet user utilizes its internet services to infringe the lawfulrights and interests of other parties, it shall be jointly liable with the internet user for damagesresulting from the infringement.

To address issues related to the hearing of civil disputes concerning the infringement of theright of communication through information networks, the PRC Supreme People’s Court issuedthe Provisions on Several Issues Concerning the Application of Law in Hearings of CivilDispute Cases on the Infringement of Information Networking Transmission Rights (《最高人民法院關於審理侵害信息網絡傳播權民事糾紛案件適用法律若干問題的規定》), which tookeffect as of January 1, 2013 and was amended in 2020. This document provides more detailedguidance as to the circumstances in which the provision by network users or network serviceproviders of other’s works, performances, and audio or video products without permission fromthe rights owner constitutes infringement of information network transmission rights. Thisdocument provides that internet service providers will be jointly liable if they assist ininfringing activities or fail to remove infringing content from their websites once they knowof the infringement or receive notice from the rights holder. This document also provides thatwhere a network service provider obtains economic advantage directly from the works,performances, and sound or visual recordings provided by the network service provider, it mustpay close attention to infringement of network information transmission rights by networkusers.

Where a trademark for whicha registration has been made is identical or similar to another trademark that has already beenregistered or been subject to a preliminary examination and approval for use on the same kindof or similar commodities or services, the application for registration of such trademark maybe rejected. Any person applying for the registration of a trademark must not prejudice theexisting right of others obtained by priority, nor may any person register in advance atrademark that has already been used by another person and has already gained a “sufficientdegree of reputation” through that person’s use. After receiving an application, the TrademarkOffice, which is under the National Intellectual Property Administration and handles trademarkregistration affairs in China, will make a public announcement if the relevant trademark passesthe preliminary examination. Within three months after such public announcement, any personmay file an objection against a trademark that has passed a preliminary examination. The PRCTrademark Office’s decisions on rejection, objection or cancellation of an application may beappealed to the National Intellectual Property Administration, whose decision may be furtherappealed through judicial proceedings. If no objection is filed within three months after thepublic announcement period or if the objection has been overruled, the PRC Trademark Officewill approve the registration and issue a registration certificate, at which point the trademarkis deemed to be registered and will be effective for a renewable ten-year period, unlessotherwise declared invalid or revoked. The licensor shall file the trademark licensing with theTrademark Office for record. The licensing of a trademark that has not been filed for recordmay not be used against a bona fide third party. “ ” and “ ” are registeredtrademarks of SINA’s subsidiaries in China and are exclusively licensed to us for use.

Domain Names. On August 24, 2017, the MIIT promulgated the Measures for Administrationof Domain Names (《互聯網域名管理辦法》) to replace the Measures for Administration ofDomain Names for the Chinese Internet (《中國互聯網絡域名註冊暫行管理辦法》). Thesemeasures regulate the registration of domain names, including the domain name “.CN”.

REGULATIONS ON FOREIGN EXCHANGE

Under the 2008 Foreign Currency Administration Rules (《中華人民共和國外匯管理條例》),if documents certifying the purposes of the conversion of RMB into foreign currency aresubmitted to the relevant foreign exchange conversion bank, the RMB will be convertible forcurrent account items, including the distribution of dividends, interest and royalties payments,and trade and service-related foreign exchange transactions. Conversion of RMB for capitalaccount items, such as direct investment, loans, securities investment and repatriation ofinvestment, however, is subject to the approval of SAFE or its local counterparts.

Under the 1996 Administration Rules of the Settlement, Sale and Payment of Foreign Exchange(《結匯、售匯及付匯管理規定》), foreign-invested enterprises may only buy, sell and/orremit foreign currencies at banks authorized to conduct foreign exchange business afterproviding valid commercial documents and, in the case of capital account item transactions,obtaining approval from SAFE or its local counterparts. Capital investments by PRC entitiesoutside of China, after obtaining the required approvals from the relevant approval authorities,such as the Ministry of Commerce and the National Development and Reform Commission ortheir local counterparts, are also required to register with SAFE or its local counterparts.

SAFE promulgated a circular on November 19, 2012, or Circular No. 59 (《國家外匯管理局關於進一步改進和調整直接投資外匯管理政策的通知》), which tightens the examination onthe authenticity of settlement of net proceeds from an offering and requires that the settlementof net proceeds shall be in accordance with the description in its prospectus.

On March 30, 2015, the SAFE issued the Circular on Reform of the Administrative Rules ofthe Payment and Settlement of Foreign Exchange Capital of Foreign-Invested Enterprises(《國家外匯管理局關於改革外商投資企業外匯資本金結匯管理方式的通知》), or SAFECircular 19, which became effective on June 1, 2015. Pursuant to SAFE Circular 19,foreign-invested enterprises may either continue to follow the current payment-based foreigncurrency settlement system or elect to follow the “conversion-at-will” regime of foreigncurrency settlement. Where a foreign-invested enterprise follows the conversion-at-will regimeof foreign currency settlement, it may convert part or all of the amount of the foreign currencyin its capital account into Renminbi at any time. The converted Renminbi will be kept in adesignated account labeled as settled but pending payment, and if the foreign-investedenterprise needs to make payment from such designated account, it still needs to go throughthe review process with its bank and provide necessary supporting documents. SAFE Circular19, therefore, has substantially lifted the restrictions on the usage by a foreign-investedenterprise of its RMB registered capital converted from foreign currencies. According to SAFECircular 19, such Renminbi capital may be used at the discretion of the foreign-investedenterprise and the SAFE will eliminate the prior approval requirement and only examine theauthenticity of the declared usage afterwards.

On June 9, 2016, SAFE issued the Circular on Reforming and Regulating Policies on theControl over Foreign Exchange Settlement of Capital Accounts, or SAFE Circular 16, whichbecame effective on the same day. Pursuant to SAFE Circular 16, enterprises registered inChina may convert their foreign debts from foreign currency to RMB on discretionary basis.SAFE Circular 16 provides an integrated standard for conversion of foreign exchange undercapital account items (including but not limited to foreign currency capital and foreign debts)on discretionary basis which applies to all enterprises registered in China. SAFE Circular 16reiterates the principle that RMB converted from foreign currency-denominated capital of a

REGULATORY OVERVIEW

– 332 –

company may not be directly or indirectly used for purposes beyond its business scope orprohibited by PRC laws or regulations, while such converted RMB shall not be provided asloans to its non-affiliated entities, or used for construction and purchase of non-self-used realestate (excluding real estate enterprises) or unless otherwise expressly provided in law, directlyor indirectly used in securities investment or other financial management excluding the bankcapital preservation products. As SAFE has not provided detailed guidelines with respect to itsinterpretation or implementation, it is uncertain how these rules will be interpreted andimplemented.

On October 23, 2019, SAFE issued the Notice of the State Administration of Foreign Exchangeon Further Facilitating Cross-border Trade and Investment, or SAFE Circular 28, which,among other things, allows all foreign-invested companies to use RMB converted from foreigncurrency-denominated capital for equity investments in China, for so long as there is a truthfulequity investment, and such equity investment does not violate applicable laws and doescomply with the negative list on foreign investment.

In utilizing the proceeds, we received from our offerings or debt financings, as an offshoreholding company with a PRC subsidiary, we may (i) make additional capital contributions toour PRC subsidiaries, (ii) establish new PRC subsidiaries and make capital contributions tothese new PRC subsidiaries, (iii) make loans to our PRC subsidiaries, or (iv) acquire offshoreentities with business operations in China in offshore transactions. However, most of these usesare subject to PRC regulations and/or approvals. For example, loans by us to our PRCsubsidiaries, which are foreign-invested enterprises, to finance their activities cannot exceedstatutory limits and must be registered with SAFE or its local branches.

REGULATIONS ON EMPLOYEE STOCK OPTIONS PLANS

In 2006, the People’s Bank of China promulgated the Administrative Measures of ForeignExchange Matters for Individuals (《個人外匯管理辦法》), setting forth the respectiverequirements for foreign exchange transactions by individuals (both PRC and non-PRCcitizens) under either the current account or the capital account. SAFE issued implementingrules for these measures in 2007 that specified approval requirements for certain capitalaccount transactions, such as a PRC citizen’s participation in employee stock ownership plansor share option plans of an overseas publicly listed company. In 2007, SAFE promulgated theApplication Procedures of Foreign Exchange Administration for Domestic IndividualsParticipating in Employee Stock Ownership Plans or Stock Option Plans of Overseas ListedCompanies (《境內個人參與境外上市公司員工持股計劃和認股期權計劃等外匯管理操作規程》). In 2012, SAFE promulgated the Notice on the Administration of Foreign ExchangeMatters for Domestic Individuals Participating in the Stock Incentive Plans of Overseas ListedCompanies (《國家外匯管理局關於境內個人參與境外上市公司股權激勵計劃外匯管理有關問題的通知》) to replace the former procedures. The new notice simplifies the requirements andprocedures for the registration of stock incentive plan participants, especially with respect tothe required application documents and the absence of strict requirements on offshore andonshore custodian banks, as were stipulated in the former procedures. The purpose of both theformer procedures and the new notice is to regulate the foreign exchange administration ofPRC resident individuals who participate in employee stock holding plans or share option plansof overseas listed companies.

Under these rules, for PRC resident individuals who participate in stock incentive plans ofoverseas publicly listed companies, which includes employee stock ownership plans, stockoption plans and other incentive plans permitted by relevant laws and regulations, a PRCdomestic qualified agent or the PRC subsidiary of such overseas listed company must, amongother things, file on behalf of such resident an application with SAFE or its local counterpart

REGULATORY OVERVIEW

– 333 –

to obtain approval for an annual allowance with respect to the purchase of foreign exchangein connection with the stock holding or exercise of share options, as PRC residents may notdirectly use overseas funds to purchase shares or exercise share options. In addition, withinthree months after any substantial changes to any such stock incentive plan, including forexample, any changes due to a merger or acquisition or changes to the domestic or overseascustodian agent, the domestic agent must update the registration with SAFE.

Under the Foreign Currency Administration Rules (《中華人民共和國外匯管理條例》), asamended in 2008, the foreign exchange proceeds of domestic entities and individuals can beremitted into China or deposited abroad, subject to the terms and conditions to be issued bySAFE. However, the implementing rules with respect to depositing foreign exchange proceedsabroad have not been issued by SAFE. The foreign exchange proceeds from the sales of sharescan be converted into RMB or transferred to such individuals’ foreign exchange savingsaccount after the proceeds have been remitted back to the special foreign exchange accountopened at the PRC domestic bank. If share options are exercised in a cashless exercise, the PRCdomestic individuals are required to remit the proceeds to special foreign exchange accounts.

Many issues with respect to the new notice require further interpretation. We and our PRCemployees who have participated in an employee stock ownership plan or share option plan aresubject to the new notice. If we or our PRC employees fail to comply with the new notice, weand our PRC employees may face sanctions imposed by the PRC foreign exchange authorityor any other PRC government authorities, including restrictions on foreign currencyconversions and additional capital contributions to our PRC subsidiaries.

In addition, the State Administration of Taxation has issued circulars concerning employeeshare options. Under these circulars, our employees working in China who exercise shareoptions will be subject to PRC individual income taxes. Our PRC subsidiaries have obligationsto file documents related to employee share options with the relevant tax authorities andwithhold individual income taxes of employees who exercise their share options.

LABOR LAWS AND SOCIAL INSURANCE

Pursuant to the PRC Labor Law (《中華人民共和國勞動法》) and the PRC Labor ContractLaw (《中華人民共和國勞動合同法》), employers must execute written labor contracts withfull-time employees. All employers must compensate their employees with wages equal to atleast the local minimum wage standards. All employers are required to establish a system forlabor safety and sanitation, strictly abide by state rules and standards and provide employeeswith workplace safety training. Violations of the PRC Labor Contract Law and the PRC LaborLaw may result in the imposition of fines and other administrative liabilities. Criminal liabilitymay arise for serious violations.

In addition, according to the PRC Social Insurance Law (《中華人民共和國社會保險法》) andthe Regulations on the Administration of Housing Provident Funds (《住房公積金管理條例》), employers in China are obliged to provide employees with welfare schemes coveringpension insurance, unemployment insurance, maternity insurance, work-related injuryinsurance, medical insurance and housing funds.

To comply with these laws and regulations, we have caused all of our full-time employees toenter into labor contracts and provide our employees with the proper welfare and employmentbenefits. If we are made subject to severe penalties or incur significant liabilities in connectionwith labor disputes or investigations, our business and results of operations may be adverselyaffected.

ACTIVITIES BY SYNDICATE MEMBERS

The underwriters of the Hong Kong Public Offering and the International Offering (together,the “Syndicate Members”) and their affiliates may each individually undertake a variety ofactivities (as further described below) which do not form part of the underwriting or stabilizingprocess.

The Syndicate Members and their affiliates are diversified financial institutions withrelationships in countries around the world. These entities engage in a wide range ofcommercial and investment banking, brokerage, funds management, trading, hedging,

UNDERWRITING

– 346 –

investing and other activities for their own account and for the account of others. In theordinary course of their various business activities, the Syndicate Members and their respectiveaffiliates may purchase, sell or hold a broad array of investments and actively trade securities,derivatives, loans, commodities, currencies, credit default swaps and other financialinstruments for their own account and for the accounts of their customers. Such investment andtrading activities may involve or relate to assets, securities and/or instruments of the Companyand/or persons and entities with relationships with the Company and may also include swapsand other financial instruments entered into for hedging purposes in connection with theGroup’s loans and other debt.

In relation to the Shares, the activities of the Syndicate Members and their affiliates couldinclude acting as agent for buyers and sellers of the Shares, entering into transactions withthose buyers and sellers in a principal capacity, including as a lender to initial purchasers ofthe Shares (which financing may be secured by the Shares) in the Global Offering, proprietarytrading in the Shares, and entering into over the counter or listed derivative transactions orlisted or unlisted securities transactions (including issuing securities such as derivativewarrants listed on a stock exchange) which have as their underlying assets, assets including theShares. Such transactions may be carried out as bilateral agreements or trades with selectedcounterparties. Those activities may require hedging activity by those entities involving,directly or indirectly, the buying and selling of the Shares, which may have a negative impacton the trading price of the Shares. All such activities could occur in Hong Kong and elsewherein the world and may result in the Syndicate Members and their affiliates holding long and/orshort positions in the Shares, in baskets of securities or indices including the Shares, in unitsof funds that may purchase the Shares, or in derivatives related to any of the foregoing.

In relation to issues by Syndicate Members or their affiliates of any listed securities having theShares as their underlying securities, whether on the Stock Exchange or on any other stockexchange, the rules of the stock exchange may require the issuer of those securities (or one ofits affiliates or agents) to act as a market maker or liquidity provider in the security, and thiswill also result in hedging activity in the Shares in most cases.

All such activities may occur both during and after the end of the stabilizing period describedin “Structure of the Global Offering”. Such activities may affect the market price or value ofthe Shares, the liquidity or trading volume in the Shares and the volatility of the price of theShares, and the extent to which this occurs from day to day cannot be estimated. It should benoted that when engaging in any of these activities, the Syndicate Members will be subject tocertain restrictions, including the following:

(a) the Syndicate Members (other than the Stabilization Manager or any person acting for it)must not, in connection with the distribution of the Offer Shares, effect any transactions(including issuing or entering into any option or other derivative transactions relating tothe Offer Shares), whether in the open market or otherwise, with a view to stabilizing ormaintaining the market price of any of the Offer Shares at levels other than those whichmight otherwise prevail in the open market; and

(b) the Syndicate Members must comply with all applicable laws and regulations, includingthe market misconduct provisions of the SFO, including the provisions prohibiting insiderdealing, false trading, price rigging and stock market manipulation.

THE HONG KONG PUBLIC OFFERING

Number of Offer Shares Initially Offered

We are initially offering 1,100,000 New Shares for subscription by the public in Hong Kongat the Public Offer Price, representing approximately 10% of the total number of Offer Sharesinitially available under the Global Offering. The number of Offer Shares initially offeredunder the Hong Kong Public Offering, subject to any reallocation of Offer Shares between theInternational Offering and the Hong Kong Public Offering, will represent approximately 0.5%of the total Shares in issue immediately following the completion of the Global Offering(assuming the Over-allotment Option is not exercised and without taking into account theShares to be issued pursuant to the Share Incentive Plans including pursuant to the exercise ofshare options or other awards that have been or may be granted from time to time).

The Hong Kong Public Offering is open to members of the public in Hong Kong as well as toinstitutional and professional investors. Professional investors generally include brokers,dealers, companies (including fund managers) whose ordinary business involves dealing inshares and other securities and corporate entities that regularly invest in shares and othersecurities.

Completion of the Hong Kong Public Offering is subject to the conditions set out in“Conditions of the Global Offering” below.

Allocation

Allocation of Offer Shares to investors under the Hong Kong Public Offering will be basedsolely on the level of valid applications received under the Hong Kong Public Offering.

The basis of allocation may vary, depending on the number of Hong Kong Offer Shares validlyapplied for by applicants. Such allocation could, where appropriate, consist of balloting, whichcould mean that some applicants may receive a higher allocation than others who have appliedfor the same number of Hong Kong Offer Shares, and those applicants who are not successfulin the ballot may not receive any Hong Kong Offer Shares.

For allocation purposes only, the total number of Hong Kong Offer Shares available under theHong Kong Public Offering (after taking into account any reallocation referred to below) willbe divided equally (to the nearest board lot) into two pools: pool A and pool B. The Hong KongOffer Shares in pool A will be allocated on an equitable basis to applicants who have appliedfor Hong Kong Offer Shares with an aggregate price of HK$5 million (excluding thebrokerage, the SFC transaction levy and the Hong Kong Stock Exchange trading fee payable)or less. The Hong Kong Offer Shares in pool B will be allocated on an equitable basis toapplicants who have applied for Hong Kong Offer Shares with an aggregate price of more thanHK$5 million (excluding the brokerage, the SFC transaction levy and the Hong Kong StockExchange trading fee payable) and up to the total value in pool B.

Investors should be aware that applications in pool A and applications in pool B may receivedifferent allocation ratios. If any Hong Kong Offer Shares in one (but not both) of the poolsare unsubscribed, such unsubscribed Hong Kong Offer Shares will be transferred to the otherpool to satisfy demand in that other pool and be allocated accordingly. For the purpose of theimmediately preceding paragraph only, the “price” for Hong Kong Offer Shares means theprice payable on application therefor (without regard to the Public Offer Price as finally

STRUCTURE OF THE GLOBAL OFFERING

– 351 –

determined). Applicants can only receive an allocation of Hong Kong Offer Shares from eitherpool A or pool B and not from both pools. Multiple or suspected multiple applications underthe Hong Kong Public Offering and any application for more than 550,000 Hong Kong OfferShares is liable to be rejected.

Reallocation

The allocation of the Offer Shares between the Hong Kong Public Offering and theInternational Offering is subject to reallocation. Paragraph 4.2 of Practice Note 18 of theListing Rules requires a clawback mechanism to be put in place which would have the effectof increasing the number of Offer Shares under the Hong Kong Public Offering to a certainpercentage of the total number of Offer Shares offered under the Global Offering if certainprescribed total demand levels are reached.

If the number of Offer Shares validly applied for under the Hong Kong Public Offeringrepresents: (a) 15 times or more but less than 50 times, (b) 50 times or more but less than 100times and (c) 100 times or more of the total number of Offer Shares initially available underthe Hong Kong Public Offering, then Offer Shares will be reallocated to the Hong Kong PublicOffering from the International Offering. As a result of such reallocation, the total number ofOffer Shares available under the Hong Kong Public Offering will be increased to 3,300,000Offer Shares (in the case of (a)), 4,400,000 Offer Shares (in the case of (b)) and 5,500,000Offer Shares (in the case of (c)), representing approximately 30%, 40% and 50% of the totalnumber of Offer Shares initially available under the Global Offering, respectively (before anyexercise of the Over-allotment Option). In each case, the additional Offer Shares reallocatedto the Hong Kong Public Offering will be allocated between pool A and pool B and the numberof Offer Shares allocated to the International Offering will be correspondingly reduced in suchmanner as the Joint Representatives deem appropriate.

In addition, the Joint Representatives may reallocate Offer Shares from the InternationalOffering to the Hong Kong Public Offering to satisfy valid applications under the Hong KongPublic Offering.

If the Hong Kong Public Offering is not fully subscribed, the Joint Representatives mayreallocate all or any unsubscribed Hong Kong Offer Shares to the International Offering, insuch proportions as the Joint Representatives deem appropriate.

The Offer Shares to be offered in the Hong Kong Public Offering and the Offer Shares to beoffered in the International Offering may be reallocated between these offerings at thediscretion of the Joint Representatives, pursuant to the alternative clawback mechanismapplied for to the Hong Kong Stock Exchange as detailed above. In accordance with theGuidance Letter HKEX-GL91-18 issued by the Hong Kong Stock Exchange, if suchreallocation is done other than pursuant to the clawback mechanism above, the maximum totalnumber of Offer Shares that may be reallocated to the Hong Kong Public Offering followingsuch reallocation shall be not more than double the initial allocation to the Hong Kong PublicOffering (i.e., 2,200,000 Shares, representing approximately 20% of the total number of OfferShares initially available under the Global Offering).

Reallocation

The total number of Offer Shares to be issued or sold pursuant to the International Offeringmay change as a result of the clawback arrangement described in “Structure of the GlobalOffering — The Hong Kong Public Offering — Reallocation”, the exercise of the Over-allotment Option in whole or in part and/or any reallocation of unsubscribed Offer Sharesoriginally included in the Hong Kong Public Offering.

If the Over-allotment Optionis exercised, an announcement will be made.

STABILIZATION

Underwriters use stabilization in some markets to facilitate the distribution of securities. Tostabilize, the underwriters may bid for, or purchase, the securities in the secondary marketduring a specified period of time, to retard and, if possible, prevent a decline in the initialpublic market price of the securities below the offer price. Such transactions may be effectedin all jurisdictions where it is permissible to do so, in each case in compliance with allapplicable laws and regulatory requirements, including those of Hong Kong. In Hong Kong, theprice at which the stabilization is effected is not permitted to exceed the Public Offer Price.

In connection with the Global Offering, the Stabilization Manager (or any person acting for it),on behalf of the Underwriters, may over-allocate or effect transactions with a view tostabilizing or supporting the market price of the Shares at a level higher than that which mightotherwise prevail for a limited period after the Listing Date in the Hong Kong market.

STRUCTURE OF THE GLOBAL OFFERING

– 354 –

However, there is no obligation on the Stabilization Manager (or any person acting for it) toconduct any such stabilizing action. Such stabilizing action, if taken: (a) will be conducted atthe absolute discretion of the Stabilization Manager (or any person acting for it) and in whatthe Stabilization Manager reasonably regards as our best interest; (b) may be discontinued atany time; and (c) is required to be brought to an end within 30 days after the last day forlodging applications under the Hong Kong Public Offering. The Company will not, and willcause its affiliates or any of its or its affiliates’ respective directors, officers, employees, or anyperson acting on its behalf or on behalf of any of the foregoing persons not to conduct anystabilizing action.

Stabilization action permitted in Hong Kong pursuant to the Securities and Futures (PriceStabilizing) Rules of the SFO includes: (a) over-allocating for the purpose of preventing orminimizing any reduction in the market price of the Shares; (b) selling or agreeing to sell theShares so as to establish a short position in them for the purpose of preventing or minimizingany reduction in the market price of the Shares; (c) purchasing, or agreeing to purchase, theShares pursuant to the Over-allotment Option in order to close out any position establishedunder Paragraphs (a) or (b) above; (d) purchasing, or agreeing to purchase, any of the Sharesfor the sole purpose of preventing or minimizing any reduction in the market price of theShares; (e) selling or agreeing to sell any Shares in order to liquidate any position establishedas a result of those purchases; and (f) offering or attempting to do anything as described inparagraphs (b), (c), (d) or (e) above.

Specifically, prospective applicants for and investors in the Offer Shares should note that:

(a) the Stabilization Manager (or any person acting for it) may, in connection with thestabilizing action, maintain a long position in the Shares;

(b) there is no certainty as to the extent to which and the time or period for which theStabilization Manager (or any person acting for it) will maintain such a long position;

(c) liquidation of any such long position by the Stabilization Manager (or any person actingfor it) and selling in the open market may have an adverse impact on the market price ofthe Shares;

(d) no stabilizing action can be taken to support the price of the Shares for longer than thestabilization period, which will begin on the Listing Date, and is expected to expire onJanuary 1, 2022, being the 30th day after the last day for lodging applications under theHong Kong Public Offering. After this date, when no further stabilizing action may betaken, demand for the Shares, and therefore the price of the Shares, could fall;

(e) the price of the Shares cannot be assured to stay at or above the Public Offer Price by thetaking of any stabilizing action; and

(f) stabilizing bids or transactions effected in the course of the stabilizing action may bemade at any price at or below the Public Offer Price and can, therefore, be done at a pricebelow the price paid by applicants for, or investors in, the Offer Shares.

We will ensure or procure that an announcement in compliance with the Securities and Futures(Price Stabilizing) Rules of the SFO will be made within seven days of the expiration of thestabilization period.

In addition, stabilization transactions with respect to the ADSs may be effected by one of theUnderwriters or its affiliates before the listing of the Shares on the Hong Kong Stock Exchangein accordance with applicable laws and regulations.

Over-allocation

Following any over-allocation of Shares in connection with the Global Offering, theStabilization Manager (or any person acting for it) may cover such over-allocations byexercising the Over-allotment Option in full or in part or by using Shares purchased by theStabilization Manager (or any person acting for it) in the secondary market at prices that do notexceed the Public Offer Price or through the Stock Borrowing Agreement as detailed below, orthrough a combination of these means.

Stock Borrowing Agreement

To cover any over-allocation of Shares in connection with the Global Offering, theStabilization Manager may choose to borrow up to 1,650,000 Shares (being the maximumnumber of Shares which may be sold pursuant to the exercise of the Over-allotment Option)from WB Estate, pursuant to the Stock Borrowing Agreement, which is expected to be enteredinto between the Stabilization Manager and WB Estate on or about the Price DeterminationDate.

The same number of Shares so borrowed must be returned to WB Estate, on or before the fifthbusiness day or in the event that the Stabilization Manager conducts stabilizing action bypurchasing ADSs in the U.S. market, the seventh business day, following the earlier of (a) thelast day on which the Over-allotment Option may be exercised and (b) the day on which theOver-allotment Option is exercised in full, or such earlier time as agreed in writing betweenthe Stabilization Manager and WB Estate.

Directors’ responsibility for the Historical Financial Information

The directors of the Company are responsible for the preparation of Historical FinancialInformation that gives a true and fair view in accordance with the basis of presentation set outin Note 2 to the Historical Financial Information, and for such internal control as the directorsdetermine is necessary to enable the preparation of Historical Financial Information that is freefrom material misstatement, whether due to fraud or error.

Reporting accountant’s responsibility

Our responsibility is to express an opinion on the Historical Financial Information and to reportour opinion to you. We conducted our work in accordance with Hong Kong Standard onInvestment Circular Reporting Engagements 200, Accountants’ Reports on HistoricalFinancial Information in Investment Circulars issued by the Hong Kong Institute of CertifiedPublic Accountants (“HKICPA”). This standard requires that we comply with ethical standardsand plan and perform our work to obtain reasonable assurance about whether the HistoricalFinancial Information is free from material misstatement.

APPENDIX IA ACCOUNTANT’S REPORT

– IA-1 –

Our work involved performing procedures to obtain evidence about the amounts anddisclosures in the Historical Financial Information. The procedures selected depend on thereporting accountant’s judgement, including the assessment of risks of material misstatementof the Historical Financial Information, whether due to fraud or error. In making those riskassessments, the reporting accountant considers internal control relevant to the entity’spreparation of Historical Financial Information that gives a true and fair view in accordancewith the basis of presentation set out in Note 2 to the Historical Financial Information in orderto design procedures that are appropriate in the circumstances, but not for the purpose ofexpressing an opinion on the effectiveness of the entity’s internal control. Our work alsoincluded evaluating the appropriateness of accounting policies used and the reasonableness ofaccounting estimates made by the directors, as well as evaluating the overall presentation ofthe Historical Financial Information.

We believe that the evidence we have obtained is sufficient and appropriate to provide a basisfor our opinion.

Opinion

In our opinion, the Historical Financial Information gives, for the purposes of the accountant’sreport, a true and fair view of the consolidated financial position of the Group as at December31, 2018, 2019 and 2020 and June 30, 2021 and of its consolidated financial performance andits consolidated cash flows for the Track Record Period in accordance with the basis ofpresentation set out in Note 2 to the Historical Financial Information.

Review of stub period comparative financial information

We have reviewed the stub period comparative financial information of the Group whichcomprises the consolidated statement of comprehensive income, the consolidated statement ofshareholders’ equity and the consolidated statement of cash flows for the six months endedJune 30, 2020 and other explanatory information (the “Stub Period Comparative FinancialInformation”). The directors of the Company are responsible for the presentation andpreparation of the Stub Period Comparative Financial Information in accordance with the basisof presentation set out in Note 2 to the Historical Financial Information. Our responsibility isto express a conclusion on the Stub Period Comparative Financial Information based on ourreview. We conducted our review in accordance with Hong Kong Standard on ReviewEngagements 2410, Review of Interim Financial Information Performed by the IndependentAuditor of the Entity issued by the HKICPA. A review consists of making inquiries, primarilyof persons responsible for financial and accounting matters, and applying analytical and otherreview procedures. A review is substantially less in scope than an audit conducted inaccordance with Hong Kong Standards on Auditing and consequently does not enable us toobtain assurance that we would become aware of all significant matters that might be identifiedin an audit. Accordingly, we do not express an audit opinion. Based on our review, nothing hascome to our attention that causes us to believe that the Stub Period Comparative FinancialInformation, for the purposes of the accountant’s report, is not prepared, in all materialrespects, in accordance with the basis of presentation set out in Note 2 to the HistoricalFinancial Information.

Under the contractual arrangements with the VIEs, the Company has the power to directactivities of the VIEs through Weibo Technology and can have assets transferred freelyout of the VIEs without restrictions. Therefore, the Company considers that there is noasset of the VIEs that can only be used to settle obligations of the VIEs and VIEs’subsidiaries, except for the registered capital and non-distributable reserve funds of theVIEs and VIEs’ subsidiaries, amounting to $144.1 million, $152.0 million, $196.6 millionand $228.5 million as of December 31, 2018, 2019 and 2020 and June 30, 2021,respectively. Since the VIEs are incorporated as limited liability companies under thePRC Company Law, creditors of the VIEs do not have recourse to the general credit ofthe Company. There is currently no contractual arrangement that would require theCompany to provide additional financial support to the VIEs. As the Company isconducting certain businesses mainly through the VIEs, the Company may provide suchsupport on a discretionary basis in the future, which could expose the Company to a loss.The total amount of costs and expenses allocated from SINA to the VIEs was $25.6million, $27.6 million, $8.7 million, $7.2 million and $1.9 million for the years endedDecember 31, 2018, 2019 and 2020 and six months ended June 30, 2020 and 2021,respectively.

Unrecognized revenue-producing assets held by the VIEs include the Internet ContentProvision License, the Online Culture Operating Permit, the domain names ofWeibo.com, Weibo.cn and Weibo.com.cn and so on. Recognized revenue-producing assetsheld by the VIEs include game technology, live streaming platform technology,supplier-relationship contracts, and trademark and domain names, which were acquiredthrough the previous acquisitions. Unrecognized revenue-producing assets, includingcustomer lists relating to advertising and marketing services, VIP membership, andgame-related services, as well as trademarks, are also held by Weibo Technology.

The following is a summary of the VIE agreements with Weimeng. The VIE agreementswith Weimeng Chuangke are substantially the same as those described below:

Loan Agreements. Weibo Technology has granted interest-free loans to the shareholdersof Weimeng with the sole purpose of providing funds necessary for those shareholders tomake capital injections to Weimeng. The term of the loans is 10 years and WeiboTechnology has the right, at its own discretion, to shorten or extend the term of the loansif necessary. In the consolidated financial statements, these loans are eliminated with thecapital of Weimeng during consolidation.

Share Transfer Agreements. Each shareholder of Weimeng has granted Weibo Technologyan option to purchase his shares in Weimeng at a purchase price equal to the amount ofcapital injection. Weibo Technology may exercise such option at any time until it hasacquired all shares of Weimeng, subject to applicable PRC laws. The options will beeffective until the earlier of (i) Weibo Technology and the shareholders of Weimeng havefully performed their obligations under these agreements, and (ii) Weibo Technology andthe shareholders of Weimeng agree in writing to terminate these agreements.

Loan Repayment Agreements. Each shareholder of Weimeng has agreed with WeiboTechnology that the interest-free loans under the loan agreements shall only be repaidthrough share transfers. Once the share transfers are completed, the purchase price for theshare transfer will be set off against the loan repayment. These agreements will beeffective until the earlier of (i) Weibo Technology and the shareholders of Weimeng havefully performed their obligations under these agreements, and (ii) Weibo Technology andthe shareholders of Weimeng agree in writing to terminate these agreements.

Agreement on Authorization to Exercise Shareholder’s Voting Power.

The authorizations are irrevocable and will not expire untilWeimeng dissolves.

Share Pledge Agreements. Each shareholder of Weimeng has pledged all of his shares inWeimeng and all other rights relevant to his rights in those shares to Weibo Technologyas security for his obligations to pay off all debts to Weibo Technology under the loanagreement. In the event of default of such obligations, Weibo Technology will be entitledto certain rights, including transferring the pledged shares to itself and disposing of thepledged shares through sale or auction. During the term of the agreements, WeiboTechnology is entitled to receive all dividends and distributions paid on the pledgedshares. The pledges will be effective until the earlier of (i) the third anniversary of the duedate of the last guaranteed debt, (ii) Weimeng and its shareholders have fully performedtheir obligations under these agreements, and (iii) Weibo Technology consents toterminate these agreements.

Exclusive Technical Services Agreement, Exclusive Sales Agency Agreement andTrademark License Agreement.

Under the exclusive technical services agreement, Weibo Technologyis engaged to provide technical services for Weimeng’s online advertising and otherrelated businesses. Under the exclusive sales agency agreement, Weimeng has grantedWeibo Technology the exclusive right to distribute, sell and provide agency services forall the products and services provided by Weimeng. Due to its control over Weimeng,Weibo Technology has the right to determine the service fee to be charged to Weimengunder these agreements by considering, among other things, the technical complexity ofthe services, the actual cost that may be incurred for providing such services, theoperations of Weimeng, applicable tax rates, planned capital expenditure and businessstrategies.

Consolidation (continued)

These VIE agreements provide Weibo Technology with the power to direct the activitiesthat most significantly affect the economic performance of the Group’s consolidated VIEsand enable the Group to receive substantially all of the economic benefits generated bythem. For the years ended December 31, 2018, 2019 and 2020 and six months ended June30, 2020 and 2021, the total amount of service fees that Weibo Technology received fromWeimeng under these service agreements and trademark license agreement was $842.6million, $832.4 million, $766.8 million, $312.7 million and $438.5 million, respectively,which were based on the actual cost incurred from providing the services and the cashposition and operations of Weimeng.

Weibo Technology, Weimeng Chuangke and Weimeng Chuangke’s shareholders haveentered into contractual arrangements which contain agreements and terms substantiallysimilar to Weibo Technology’s contractual arrangements with Weimeng and Weimeng’sshareholders described above.

Minority Investment in Weimeng

In April 2020, WangTouTongDa (Beijing) Technology Co., Ltd., an entity affiliated withZhongWangTou (Beijing) Technology Co., Ltd., made an investment of approximatelyRMB10.7 million in Weimeng for 1% of Weimeng’s enlarged registered capital. Suchthird party minority stake holder is entitled to customary economic rights in proportionto its equity ownership, and certain minority shareholder rights such as the right toappoint a director to Weimeng’s three-member board of directors, and veto rights overcertain matters related to content decision, and certain future financings of Weimeng.

The third party minority stake holder is not a party to the contractual arrangementsmentioned above that are currently in effect among Weimeng, Weibo Technology andWeimeng’s other shareholders. As such, despite the fact that the Company is still able toenjoy economic benefits and exercise effective control over Weimeng and its subsidiaries,the Company is not able to purchase or have the third party minority stake holder pledgeits 1% equity interests in Weimeng in the same manner as agreed under existingcontractual arrangements, nor is it granted the authorization of voting rights over these1% equity interests. The Company believes Weibo Technology, the wholly-owned PRCsubsidiary, still controls and is the primary beneficiary of Weimeng as it continues to havea controlling financial interest in Weimeng pursuant to ASC 810-10-25-38A after theissuance of such 1% equity interests.

The Company believes that the contractual arrangements among the WFOE, VIEs andVIEs’ shareholders are in compliance with the current PRC laws and legally enforceable.However, uncertainties in the interpretation and enforcement of the PRC laws, regulationsand policies could limit the Company’s ability to enforce these contractual arrangements.As a result, the Company may be unable to consolidate the VIEs and VIEs’ subsidiariesin the consolidated financial statements. The Company’s ability to control the VIEs also

depends on the authorization by the shareholders of the VIEs to exercise voting rights onall matters requiring shareholder approval in the VIEs. The Company believes that theagreements on authorization to exercise shareholder’s voting power are legallyenforceable. In addition, if the legal structure and contractual arrangements with the VIEswere found to be in violation of any future PRC laws and regulations, the Company maybe subject to fines or other actions. The Company believes the possibility that it will nolonger be able to control and consolidate the VIEs as a result of the aforementioned risksand uncertainties is remote.

2. Significant Accounting Policies

This note provides a list of significant accounting policies adopted in the preparation ofthe Historical Financial Information. These policies have been consistently applied to allthe years presented, unless otherwise stated. The Historical Financial Information is forthe group consisting of the Company and its subsidiaries.

Basis of presentation

The preparation of the Group’s consolidated financial statements is in conformity withU.S. GAAP. The consolidated financial statements include the accounts of Weibo, itswholly owned subsidiaries, VIEs, and VIEs’ subsidiaries. All significant intercompanybalances and transactions have been eliminated.

Use of estimates

Conformity with U.S. GAAP requires the use of estimates and judgments that affect thereported amounts in the consolidated financial statements and accompanying notes. Theseestimates form the basis for judgments the management makes about the carrying valuesof the assets and liabilities, which are not readily apparent from other sources. U.S.GAAP requires making estimates and judgments in several areas, including, but notlimited to, the basis of consolidation, revenue recognition, fair value accounting, incometaxes, goodwill and other long-lived assets, allowances for credit losses, stock-basedcompensation, the estimated useful lives of assets, convertible debt, businesscombination, and foreign currency. The management bases the estimates and judgmentson historical information and on various other assumptions that management believes arereasonable under the circumstances. Actual results could differ materially from suchestimates.

Revenue recognition

In May 2014, the Financial Accounting Standards Board (“FASB”) issued, ASU 2014-09,“Revenue from Contracts with Customers (Topic 606)”. The Group adopted the newrevenue guidance since January 1, 2018 using the modified retrospective method. Resultsfor reporting periods beginning on or after January 1, 2018 are presented under ASC 606,while prior period amounts are not adjusted and continue to be reported in accordancewith the Group’s historic accounting method under ASC 605. The main impacts are a) thepresentation of value added tax recognized in revenue from “gross” to “net”, whichresults in equal decrease of revenues and cost of revenues, and b) the recognition ofrevenues and expenses at fair value for advertising barter transactions, which mainlyresults in the increase of revenue and advertising expenses.

Impact of Adoption

The cumulative-effect adjustment on the retained earnings as of January 1, 2018 relatedto the initial application of the new revenue standard was $0.6 million, which resultedfrom advertising barter transactions. The adoption resulted in an increase of $2.1millionin deferred revenue and an increase of $0.6 million in other current assets as of December31, 2018.

The table below summarized the impact of adoption of the new revenue standard on theGroup’s consolidated statement of comprehensive income for the year ended December31, 2018.

Under ASC 606, revenues are recognized when control of the promised goods or servicesis transferred to customers, in an amount that reflects the consideration the Group expectsto be entitled to in exchange for those goods or services. The Group identifies its contractswith customers and all performance obligations within those contracts. The Group thendetermines the transaction price and allocates the transaction price to the performanceobligations within the Group’s contracts with customers, recognizing revenue when, or as,the Group satisfies its performance obligations.

Impact of Adoption (continued)

The Group does not believe that significant management judgments are involved inrevenue recognition, but the amount and timing of the Group’s revenues could bedifferent for any period if management made different judgments. Certain customers mayreceive sales rebates, which are accounted for as variable consideration. The Groupestimates annual expected revenue volume of each individual agent with reference to theirhistorical results. The Group recognizes revenue for the amount of fees it receives fromits advertisers, after deducting estimated sales rebates and net of value-added tax (“VAT”)under ASC 606. The Group believes that there will not be significant changes to itsestimates of variable consideration.

Revenue disaggregated by revenue source for the years ended December 31, 2018, 2019and 2020 and six months ended June 30, 2020 and 2021 consists of the following:

Year Ended December 31,Six Months Ended

Total revenues $1,718,518 $1,766,914 $1,689,931 $710,782 $1,033,362

The Group enters into contracts with its customers, which may give rise to contract assets(unbilled revenue) or contract liabilities (deferred revenue). The payment terms andconditions within the Group’s contracts vary by the type and location of its customers andproducts or services purchased, the substantial majority of which are due in less than oneyear. Deferred revenues related to unsatisfied performance obligations at the end of theperiod are mainly from the customer advance of the advertising and marketing servicesand the sales of the fee-based services, such as VIP membership, live streaming, andvirtual currency or in-game virtual items sold for game related services. The deferredrevenues are recognized based on customers’ consumption or amortized on a straight-linebasis through the service period for different products/services. Due to the generallyshort-term duration of the contracts, the majority of the performance obligations aresatisfied in the following reporting period. The amount of revenue recognized that wasincluded in the deferred revenue balance at the beginning of the periods was $67.2million, $88.3 million, $91.5 million, and $104.5 million for the years ended December31, 2018, 2019 and 2020 and six months ended June 30, 2021, respectively.

Practical Expedients and Exemptions

The Group generally expenses sales commissions when incurred because the amortizationperiod is generally one year or less. These costs are recorded within sales and marketingexpenses.

Advertising and marketing revenues

Advertising and marketing revenues are derived principally from online advertising,including social display ads and promoted marketing. Social display ad arrangementsallow customers to place advertisements on particular areas of the Group’s platform orwebsite in particular formats and over particular periods of time, which is typically nomore than three months. The Group enters into cost per mille (“CPM”), or cost perthousand impressions, advertising arrangements with the customers, under which theGroup recognizes revenues based on the number of times that the advertisement has beendisplayed. The Group also enters into cost per day (“CPD”) advertising arrangements withcustomers, under which the Group recognizes revenues ratably over the contract periods.Promoted marketing arrangements are primarily priced based on CPM. Under the CPMmodel, customers are obligated to pay when the advertisement is displayed.

The Group’s majority revenue transactions are based on standard business terms andconditions, which are recognized net of agency rebates. The agency rebates are accountedfor as variable consideration and are estimated during interim periods based on estimatedannual revenue volume of each individual agent with reference to their historical results,which involves accounting judgment. The Group believes its estimation approach invariable consideration results in revenue recognition in a manner consistent with theunderlying economics of the transaction.

The Group’s contracts with customers may include multiple performance obligations,which primarily consist of combination of service to allow customers to placeadvertisements on different areas of its platform or website. For such arrangements,advertising arrangements involving multiple deliverables are broken down into single-element arrangements based on their stand-alone selling price for revenue recognitionpurposes. The estimation of stand-alone selling price involves significant judgment,especially for the deliverables that have not been sold separately. For those deliverables,the Group determines best estimate of the stand-alone selling price by taking intoconsideration of the pricing of advertising areas of the Group’s platform or website withsimilar popularities and advertisements with similar formats and quoted prices fromcompetitors and other market conditions. The Group believes the estimation approach instand-alone selling price and allocation of the transaction price on a relative stand-aloneselling price to each performance obligation results in revenue recognition in a mannerconsistent with the underlying economics of the transaction and the allocation principleincluded in ASC 606. Revenues recognized with reference to best estimation of sellingprice were immaterial for all periods presented. Most of such contracts have allperformance obligations completed within one year. Changes in judgments on theseassumptions and estimates could materially impact the timing or amount of revenuerecognition. Contracts with customers of online advertising may require cooperation from

third parties. The Group pays a predetermined portion of revenues it earned fromadvertising contracts to the third parties such as key opinion leaders who participate inadvertising and promotion activities by monetizing their social assets. The Group hasdetermined that it is the principal in these transactions, as it is primarily responsible forfulfilling all the obligations related to advertising contracts. The Group has discretion inestablishing pricing of the contracts and controls the advertising inventory before thedelivery to customers. The Group records revenues derived from such contracts on a grossbasis and the portion paid to the third parties is recognized as cost of revenues.

Revenues from barter transactions are recognized during the period in which theadvertisements are displayed on the Group’s properties. Barter transactions in whichphysical goods or services are received in exchange for advertising services are recordedbased on the fair values of the goods or services received.

Value-added services revenues

The Group generates value-added services revenues principally from fee-based services,mainly including VIP membership, live streaming, and game-related services. Othervalue-added services revenues mainly include the revenues from the provision of trafficacquisition services to various customers. Revenues from these services are recognizedwhen control of the promised services is transferred to customers, in an amount thatreflects the consideration the Group expects to be entitled to in exchange for thoseservices.

VIP membership. VIP membership mainly includes a service package consisting of oneperformance obligation of providing user certification and preferential benefits, such asdaily priority listings and higher quota for following user accounts. Prepaid VIPmembership fees are recorded as deferred revenue and recognized as revenue ratably overthe contract period of the membership service.

Live streaming. Live streaming generates revenue from sales of virtual items on the livestreaming platform (“Yizhibo”). Users can access the platform and view the livestreaming content and interact with the broadcasters for free.

The Group designs, creates and offers various virtual items for sales to users withpre-determined selling price. Each virtual item is considered as a distinctive performanceobligation. Sales proceeds are recorded as deferred revenue and recognized as revenuebased on the consumption of the virtual items. Users can purchase and present virtualitems to broadcasters to show support for their favorite ones. Under the arrangementswith broadcasters or broadcaster agencies, the Group shares with them a portion of therevenues derived from the consumption of virtual items. Revenues derived from the saleof virtual items are recorded on a gross basis as the Group has determined that it acts asthe principal to fulfill all obligations related to the live streaming services. The portionpaid to broadcasters and/or broadcaster agencies is recognized as cost of revenues. TheGroup does not have further obligations to the user after the virtual items are consumed.

Game-related services. Game-related service revenues are mostly generated from thepurchase of virtual items by game players through the Group’s platform, including items,avatars, skills, privileges or other in game consumables, features or functionality, withinthe games. The Group’s performance obligation is to provide on-going game services toplayers who purchased virtual items to gain an enhanced game-playing experience. Eachvirtual item is considered as a distinctive performance obligation. The Group collectspayments from the game players in connection with the sale of virtual currency, whichcan be used to purchase virtual items in online games. For games co-operated with thirdparty developers, revenue is recorded on a gross basis for games that the Group is actingas the principal in fulfilling all obligations related to the games and revenue is recordednet of predetermined revenue sharing with the game developers for games in which theGroup is not acting as the principal in fulfilling all obligations. Sales of virtual currenciesare recognized as revenues over the estimated lifespans of in-game virtual items. Theestimated lifespans of different virtual items are determined by the management based oneither the expected user relationship periods or the stipulated period of validity of therelevant virtual items depending on the respective term of virtual items. Virtual currencysold for game-related services in excess of recognized revenues is recorded as deferredrevenues.

Cost of revenues

Cost of revenues consists mainly of costs associated with the maintenance of platform,which primarily include bandwidth and other infrastructure costs, revenue-share cost,advertisement production cost, labor cost and turnover taxes levied on the revenues, partof which were allocated from SINA. The Group is subject to 3% cultural businessconstruction fees for its advertising and marketing revenues, which is included in cost ofrevenues. Starting from July 1, 2019, the 3% cultural business construction fees wasreduced to 1.5%. Moreover, as part of the measures taken by the government to ease thenegative impact from Covid-19 pandemic, the cultural business construction fees wasexempted for the fiscal year of 2020 and 2021. An aggregate of $24.6 million and $11.5million cultural business construction fees was exempted for the year ended December31, 2020 and six months ended June 30, 2021, respectively.

Sales and marketing expenses

Sales and marketing expenses consist mainly of online and offline advertising andpromotional expenses, salary, benefits and commission expenses, and facility expenses.Advertising and promotional expenses generally represent the expenses of promotions ofcorporate image and product marketing. The Group expenses all advertising andpromotional expenses as incurred and classifies these expenses under sales and marketingexpenses. For the years ended December 31, 2018, 2019 and 2020 and six months endedJune 30, 2020 and 2021, the advertising and promotional expenses were $428.8 million,$352.3 million, $330.9 million, $156.9 million and $219.9 million, respectively.

Product development expenses

Product development expenses consist mainly of payroll-related expenses andinfrastructure costs incurred for enhancement to and maintenance of the Group’splatform, as well as costs associated with new product development and productenhancements, part of which were allocated from SINA. The Group expenses all costsincurred for the planning and post implementation phases of development and costsassociated with repair or maintenance of the existing site or the development of platformcontent. Since inception, the amount of costs qualifying for capitalization has beenimmaterial and, as a result, all product development costs have been expensed asincurred.

Stock-based compensation

All stock-based awards to employees and directors, such as stock options and restrictedshare units (“RSUs”), are measured at the grant date based on the fair value of the awards.Stock-based compensation, net of forfeitures, is recognized as expenses on a straight-linebasis over the requisite service period, which is the vesting period.

The Group uses the Black-Scholes option pricing model to estimate the fair value of stockoptions. The determination of estimated fair value of stock-based payment awards on thegrant date using an option pricing model is affected by the fair value of the Company’sordinary shares as well as assumptions regarding a number of complex and subjectivevariables. These variables include the expected value volatility of the Company over theexpected term of the awards, actual and projected employee stock option exercisebehaviors, a risk-free interest rate and expected dividends, if any. Options grantedgenerally vest over four years.

The Group recognizes the estimated compensation cost of restricted share units based onthe fair value of its ordinary shares on the date of the grant. The Group recognizes thecompensation cost, net of estimated forfeitures, over a vesting term of generally fouryears for service-based restricted share units. The Group also recognizes thecompensation cost of performance-based restricted share units, net of estimatedforfeitures, if it is probable that the performance condition will be achieved at the end ofeach reporting period.

Forfeitures are estimated at the time of grant and revised in subsequent periods if actualforfeitures differ from those estimates. The Group uses historical data to estimatepre-vesting option and records stock-based compensation expense only for those awardsthat are expected to vest. See Note 7 Stock-based Compensation for further discussion onstock-based compensation.

Taxation

Income taxes

Income taxes are accounted for using the asset and liability approach. Under thisapproach, income tax expense is recognized for the amount of taxes payable or refundablefor the current year. In addition, deferred tax assets and liabilities are recognized forexpected future tax consequences of temporary differences between the financialreporting and tax bases of assets and liabilities, and for operating losses and tax creditcarry forwards. The Group records a valuation allowance to reduce deferred tax assets toan amount for which realization is more likely than not.

In December 2019, the FASB issued ASU No. 2019-12, Simplifying the Accounting forIncome Taxes, as part of its initiative to reduce complexity in accounting standards. Theamendments in the ASU are effective for fiscal years beginning after December 15, 2020,including interim periods therein. Early adoption of the standard is permitted, includingadoption in interim or annual periods for which financial statements have not yet beenissued. The Group adopted the ASU on January 1, 2021, which did not have a materialimpact on the consolidated financial statements.

Uncertain tax positions. To assess uncertain tax positions, the Group applies a more likelythan not threshold and a two-step approach for the tax position measurement and financialstatement recognition. Under the two-step approach, the first step is to evaluate the taxposition for recognition by determining if the weight of available evidence indicates thatit is more likely than not that the position will be sustained, including resolution of relatedappeals or litigation processes, if any. The second step is to measure the tax benefit as thelargest amount that is more than 50% likely of being realized upon settlement.

Short-term investments

Short-term investments represent bank time deposits and wealth management productswhich are certain deposits with variable interest rates or principal not-guaranteed withcertain financial institutions. Their original maturities are of greater than three months butless than one year. In accordance with ASC 825, Financial Instruments, for wealthmanagement products with the interest rate indexed to performance of underlying assets,the Group elected the fair value method at the date of initial recognition and carried theseinvestments at fair value. Changes in the fair value are reflected in the consolidatedstatements of comprehensive income as interest income.

Accounts receivable and allowances for doubtful accounts/credit losses

Prior to January 1, 2020, accounts receivable are recorded and carried at the originalinvoiced amount less an allowance for any potential uncollectible amounts. The Groupmaintains an allowance for doubtful accounts which reflects its best estimate of amountsthat will not be collected. The Group determines the allowance for doubtful accountsbased on historical rolling average bad debt rate in the prior period and other factors, suchas credit-worthiness of the customers and the age of the receivable balances. The Groupalso provides specific provisions for bad debts when facts and circumstances indicate that

APPENDIX IA ACCOUNTANT’S REPORT

II. NOTES TO THE HISTORICAL FINANCIAL INFORMATION (Continued)

2. Significant Accounting Policies (continued)

Accounts receivable and allowances for doubtful accounts/credit losses (continued)

the receivable is unlikely to be collected. If the financial condition of the Group’scustomers were to deteriorate, resulting in impairment of their ability to make payments,more bad debt allowances may be required.

In 2016, the FASB issued ASC Topic 326, which amends previously issued guidanceregarding the impairment of financial instruments by creating an impairment model thatis based on expected losses. The guidance is applicable to accounts receivable and theGroup adopted ASC Topic 326 on January 1, 2020. Accounts receivable are recorded atthe original amounts less an allowance for any potential uncollectible amounts. TheGroup makes estimates of expected credit and collectability trends for the allowance forcredit losses based upon assessment of various factors, including historical experience,the age of the accounts receivable balances, credit-worthiness of the customers, currenteconomic conditions, reasonable and supportable forecasts of future economic conditions,and other factors that may affect its ability to collect from the customers. The Group alsoprovides specific provisions for allowance when facts and circumstances indicate that thereceivable is unlikely to be collected. Expected credit losses for accounts receivable arerecorded as general and administrative expenses on the consolidated statements ofcomprehensive income. The initial impact of applying ASC Topic 326 on the consolidatedfinancial statements is immaterial to the Group’s retained earnings as of January 1, 2020.

ASC Topic 326 is also applicable to the loans to and interest receivable from other relatedparties included in the prepaid expenses and other current assets on the consolidatedbalance sheets. Management estimates the allowance for credit losses on loans andinterest receivable not sharing similar risk characteristic on an individual basis, based onlifetime expected credit losses of these loans and interest receivable by estimating loancollection schedule, then discounting these cash flows to their present values. The keyfactors considered when determining the above allowances for credit losses includeestimated loan collection schedule, discount rate, financial condition and performancedata of the borrowers and reasonable and supportable performance forecasts.

Fair value measurements

Financial instruments

All financial assets and liabilities are recognized or disclosed at fair value in theconsolidated financial statements on a recurring basis. Accounting guidance defines fairvalue as the price that would be received from selling an asset or paid to transfer aliability in an orderly transaction between market participants at the measurement date.When determining the fair value measurements for assets and liabilities required orpermitted to be recorded at fair value, the Group considers the principal or mostadvantageous market in which it would transact and it considers assumptions that marketparticipants would use when pricing the asset or liability.

The Group measures the equity method investments at fair value on a non-recurring basisonly if an impairment charge were to be recognized. For those investments withoutreadily determinable fair value, the Group measures them at fair value when observableprice changes are identified or impairment charge was recognized. The fair values of the

Fair value measurements (continued)

Financial instruments (continued)

Group’s privately held investments as disclosed are determined based on the discountedcash flow model using the discount curve of market interest rates or based on the similartransaction price in the market directly. The fair values of the Group’s long-terminvestments in the equity securities of publicly listed companies are measured usingquoted market prices. The Group’s non-financial assets, such as intangible assets,goodwill, fixed assets and operating lease assets, would be measured at fair value only ifthey were determined to be impaired.

Accounting guidance establishes a fair value hierarchy that requires an entity to maximizethe use of observable inputs and minimize the use of unobservable inputs when measuringfair value. A financial instrument’s categorization within the fair value hierarchy is basedupon the lowest level of input that is significant to the fair value measurement.Accounting guidance establishes three levels of inputs that may be used to measure fairvalue:

• Level 1 applies to assets or liabilities for which there are quoted prices in activemarkets for identical assets or liabilities.

• Level 2 applies to assets or liabilities for which there are inputs other than quotedprices included within Level 1 that are observable for the asset or liability such asquoted prices for similar assets or liabilities in active markets; quoted prices foridentical asset or liabilities in markets with insufficient volume or infrequenttransactions (less active markets); or model-derived valuations in which significantinputs are observable or can be derived principally from, or corroborated by,observable market data.

• Level 3 applies to asset or liabilities for which there are unobservable inputs to thevaluation methodology that are significant to the measurement of the fair value ofthe assets or liabilities.

The carrying amount of cash and cash equivalents, short-term investments, accountsreceivable due from third parties, accounts receivable due from Alibaba, accountsreceivable due from other related parties, amount due from/to SINA, accounts payable,accrued and other liabilities approximates fair value because of their short-term nature.See Note 15 Fair Value Measurement for additional information.

Long-term investments

Long-term investments are comprised of investments in publicly traded companies,privately held companies, and limited partnerships. The Group uses the equity method toaccount for ordinary-share-equivalent equity investments on which it has significantinfluence but does not own a majority equity interest or otherwise control.

Long-term investments (continued)

Before the adoption of ASU 2016-01 in 2018, the Group used cost method to account forequity investments over which the Group does not have significant influence, or theinvestments in which the Group holds equity shares that are not common shares/in-substance common share without readily determinable fair value. For marketable equitysecurities, the Group reported them at fair value and accounted for them as available-for-sale (“AFS”) securities under long-term investments.

After adopting ASU 2016-01 on January 1, 2018, the Group measures investments inequity securities, other than equity method investments, at fair value through earnings.For those investments without readily determinable fair values, the Group elects to recordthese investments at cost, less impairment, and plus or minus subsequent adjustments forobservable price changes. Under this measurement alternative, changes in the carryingvalue of the investments will be recognized in consolidated statement of comprehensiveincome, whenever there are observable price changes in orderly transactions for theidentical or similar investment of the same issuer.

The marketable equity securities were reclassified as investments with readilydeterminable fair values under the ASU 2016-01. There will no longer be an available-for-sale classification for equity securities. The cumulative effects of applying theguidance to the Group’s consolidated balance sheets were the reclassification ofunrealized loss of $1.0 million from accumulated other comprehensive income to retainedearnings as of January 1, 2018.

Due to the adoption of ASU 2016-01, the AFS was reclassified to investment with readilydeterminable fair values beginning January 1, 2018, the Group recorded $2.8 million loss,which is unrealized in 2018, and the fair value was $1.5 million as of December 31, 2018.

Pursuant to ASC 321, for equity investments measured at fair value with changes in fairvalue recorded in earnings, the Group does not assess whether those securities areimpaired. For equity investments without readily determinable fair value for which theGroup has elected to use the measurement alternative, the Group makes a qualitativeassessment of whether the investment is impaired at each reporting date, applyingsignificant judgement in considering various factors and events including a) adverseperformance of investees; b) adverse industry developments affecting investees; and c)adverse regulatory, social, economic or other developments affecting investees. If aqualitative assessment indicates that the investment is impaired, the Group estimates theinvestment’s fair value in accordance with the principles of ASC 820. If the fair value isless than the investment’s carrying value, the Group recognizes an impairment loss in netincome equal to the difference between the carrying value and fair value. Significantjudgment is applied by the Group in estimating the fair value to determine if animpairment exists, and if so, to measure the impairment losses for these equity securityinvestments. These judgments include the selection of valuation methods in estimatingfair value and the determination of key valuation assumptions used, which comprised thecash flow forecasts and critical assumptions used in cash flow forecasts, such as theinvestees’ revenue growth rate, terminal growth rate, discount rate, selection ofcomparable companies and multiples, estimated volatility rate and discount for lack ofmarketability.

Long-term investments (continued)

Investments in entities over which the Group can exercise significant influence and holdsan investment in voting common shares or in-substance common shares (or both) of theinvestee but does not own a majority equity interest or control are accounted for using theequity method of accounting in accordance with ASC topic 323 (“ASC 323”), Investment— Equity Method and Joint Ventures. Under the equity method, the Group initiallyrecords its investments at cost and the difference between the cost of the equity investeeand the fair value of the underlying equity in the net assets of the equity investee isrecognized as equity method goodwill, which is included in the equity method investmenton the consolidated balance sheets. The Group subsequently adjusts the carrying amountof the investments to recognize the Group’s proportionate share of each equity investee’snet income or loss into earnings after the date of investment. The Group evaluates theequity method investments for impairment under ASC 323. An impairment loss on theequity method investments is recognized in earnings when the decline in value isdetermined to be other-than-temporary.

In January 2020, the FASB issued ASU No. 2020-01, Investments — Equity Securities(Topic 321), Investments — Equity Method and Joint Ventures (Topic 323), andDerivatives and Hedging (Topic 815) — Clarifying the Interactions between Topic 321,Topic 323, and Topic 815 (a consensus of the Emerging Issues Task Force). Theamendments in this update clarify the interaction of the accounting for equity securitiesunder Topic 321 and investments accounted for under the equity method of accounting inTopic 323 and the accounting for certain forward contracts and purchased optionsaccounted for under Topic 815. For public business entities, the amendments in thisUpdate are effective for fiscal years beginning after December 15, 2020, and interimperiods within those fiscal years. For all other entities, the amendments are effective forfiscal years beginning after December 15, 2021, and interim periods within those fiscalyears. Early adoption is permitted. The Group adopted the ASU on January 1, 2021, whichdid not have a material impact on the consolidated financial statements.

Business combination

Business combinations are recorded using the purchase method of accounting, and thecost of an acquisition is measured as the aggregate of the fair values at the date ofexchange of the assets given, liabilities incurred, and equity instruments issued as well asthe contingent considerations and all contractual contingencies as of the acquisition date.The costs directly attributable to the acquisition are expensed as incurred. Identifiableassets, liabilities and contingent liabilities acquired or assumed are measured separatelyat their fair value as of the acquisition date, irrespective of the extent of anynon-controlling interests. The excess of the (i) the total of consideration paid, fair valueof the non-controlling interests and acquisition date fair value of any previously heldequity interest in the subsidiary acquired over (ii) the fair value of the identifiable netassets of the subsidiary acquired is recorded as goodwill. If the consideration ofacquisition is less than the fair value of the net assets of the subsidiary acquired, thedifference is recognized directly in the consolidated statements of comprehensive income.

Leases

Prior to the adoption of ASC 842 in 2019, the Group accounted for leases under ASC 840,Leases. The Group leases office space under operating lease agreements with variousexpiration dates. Rental expense is recognized from the date of initial possession of theleased property on a straight-line basis over the term of the lease, part of which wasallocated from SINA. Certain lease agreements contain rent holidays, which arerecognized on a straight-line basis over the lease term. Lease renewal periods areconsidered on a lease-by-lease basis and are generally not included in the initial leaseterms.

In February 2016, the FASB issued a new standard on leases, ASU 2016-02, “Leases(Topic 842)”, which requires a lessee to recognize assets and liabilities arising fromoperating leases. A lessee should recognize a liability to make lease payments (the LeaseLiability) and a right-of-use asset (the Operating Lease Assets) representing its right touse the underlying asset for the lease term. For leases with a term of twelve months orless, a lessee is permitted to make an accounting policy choice not to recognize leaseassets and lease liabilities. In July 2018, the FASB issued an amendment, ASU 2018-11,which provides another transition method in addition to the existing transition methods byallowing entities to initially apply the new leases standard at the effective date andrecognize a cumulative-effect adjustment to the opening balance of retained earnings inthe period of adoption and to not retrospectively adjust prior periods financial statements.

On January 1, 2019, the Group adopted the new lease standard using the transition methodby applying the standard to all leases existing at the date of initial application. The Groupchose to not recognize lease assets and lease liabilities for leases with a term of twelvemonths or less, to not separate non-lease components from lease components, and to notreassess lease classification, treatment of initial direct costs or whether an existing orexpired contract contains a lease according to the practical expedients permitted under thetransition method.

The Group did not retrospectively adjust the prior comparative periods. Under the newlease standard, the Group determines if an arrangement is or contains a lease at inception.Right-of-use assets and liabilities are recognized at lease commencement date based onthe present value of remaining lease payments over the lease terms. The Group considersonly payments that are fixed and determinable at the time of lease commencement. Theadoption of new leasing guidance resulted in recognition of $14.4 million of operatinglease assets and $14.9 million of leasing liabilities as of January 1, 2019, respectively, andno impact to the beginning retained earnings of the year.

Long-lived assets

Property and equipment

Property and equipment are stated at cost less accumulated depreciation, amortization andimpairment, if any. Depreciation is computed using the straight-line method over theestimated useful lives of the assets, generally from three to four years for computers andequipment and five years for furniture and fixtures. Leasehold improvements areamortized over the shorter of the estimated useful lives of the assets or the remaininglease term. Depreciation expenses were $18.5 million, $22.4 million, $26.5 million, $12.0million and $16.1 million for the years ended December 31, 2018, 2019 and 2020 and sixmonths ended June 30, 2020 and 2021, respectively.

Goodwill

Goodwill represents the excess of the purchase price over the fair value of the identifiableassets and liabilities acquired as a result of the Group’s acquisitions of interests in itssubsidiaries, consolidated VIEs and VIEs’ subsidiaries. The Group assesses goodwill forimpairment in accordance with ASC Subtopic 350-20 (“ASC 350-20”), Intangibles —Goodwill and Other: Goodwill, which requires that goodwill be tested for impairment atthe reporting unit level at least annually and more frequently upon the occurrence ofcertain events, as defined by ASC 350-20. The guidance provides the option that theGroup may first assess qualitative factors to determine whether it is necessary to performthe quantitative goodwill impairment test, by taking into consideration ofmacroeconomics, overall financial performance, industry and market conditions and theshare price of the Group. If determined to be necessary, the quantitative impairment testshall be used to identify goodwill impairment and measure the amount of a goodwillimpairment loss to be recognized (if any). Application of a goodwill impairment testrequires significant management judgment, including the identification of reporting units,assigning assets and liabilities to reporting units, assigning goodwill to reporting units,and determining the fair value of each reporting unit. Judgment in estimating the fairvalue of reporting units includes estimating future cash flows, determining appropriatediscount rates and making other assumptions. Changes in these estimates and assumptionscould materially affect the determination of fair value for each reporting unit. During2018, impairment indicators were identified by the Group for the game related reportingunit including adversely policy change on game industry and failure to meet forecastedfinancial performance supporting the goodwill without prospect of future recovery. Themanagement fully impaired the goodwill arising from acquisition of several gamebusiness amounting $10.6 million as the management expect it’s hard for the gamebusiness to recover. For the years ended December 31, 2019, 2020 and six months endedJune 30, 2020 and 2021, no impairment indicator was noted by performing qualitativeanalysis, therefore, no provision was recorded.

Intangible assets other than goodwill

Intangible assets arising from acquisitions are recognized at fair value upon acquisitionand amortized on a straight-line basis over their estimated useful lives, generally fromthree to ten years. Long-lived assets and certain identifiable intangible assets other thangoodwill to be held and used are reviewed for impairment whenever events or changes incircumstances indicate that the carrying amount of such assets may not be recoverable.

2. Significant Accounting Policies (continued)

Long-lived assets (continued)

Intangible assets other than goodwill (continued)

Determination of recoverability is based on an estimate of undiscounted future cash flowsresulting from the use of the asset and its eventual disposition. Measurement of anyimpairment loss for long-lived assets and certain identifiable intangible assets thatmanagement expects to hold or use is based on the amount by which the carrying valueexceeds the fair value of the asset. Judgment is used in estimating future cash flows,determining appropriate discount rates and making other assumptions. Changes in theseestimates and assumptions could materially affect the determination of the asset’s fairvalue.

Convertible debt and unsecured senior notes

The Group determines the appropriate accounting treatment of its convertible debt inaccordance with the terms in relation to the conversion feature. After considering theimpact of such features, the Group may account for such instrument as a liability in itsentirety, or separate the instrument into debt and equity components following therespective guidance described under ASC 815 Derivatives and Hedging and ASC 470Debt.

The debt discount, if any, together with related issuance cost are subsequently amortizedas interest expense over the contractual life. The Group presented the issuance costs ofdebt as a direct deduction from the related debt during the periods presented.

The unsecured senior notes are recognized initially at fair value, net of debt discounts orpremiums, if any, issuance costs and other incidental fees, all of which are recorded as adirect deduction of the proceeds received from issuing the unsecured senior notes and therelated accretion is recorded as interest expense in the consolidated statement ofcomprehensive income over the estimated term using the effective interest method.

Deferred revenues

Deferred revenues consist of contractual billings in excess of recognized revenue andpayments received in advance of revenue recognition, which are mainly from thecustomer advance of the advertising and marketing services and the sales of the fee-basedservices, such as VIP membership, live streaming, and virtual currency or in-game virtualitems sold for game related services.

Non-controlling interests

For the Company’s majority-owned subsidiaries and VIEs, non-controlling interests arerecognized to reflect the portion of their equity that is not attributable, directly orindirectly, to the Company as the controlling shareholder. To reflect the economic interestheld by non-controlling shareholders, net income/loss attributable to the non-controllingordinary shareholders is recorded as non-controlling interests in the Company’sconsolidated statements of comprehensive income. Non-controlling interests are

Non-controlling interests (continued)

classified as a separate line item in the equity section of the Company’s consolidatedbalance sheets and have been separately disclosed in the Company’s consolidatedfinancial statements to distinguish the interests from that of the Company.

Foreign currency

The Company’s reporting currency and functional currency are the U.S. dollar. TheGroup’s operations in China and in international regions use their respective currenciesas their functional currencies. The financial statements of these subsidiaries are translatedinto U.S. dollars using period-end rates of exchange for assets and liabilities and averagerates of exchange in the period for revenues, costs and expenses. Translation gains andlosses are recorded in accumulated other comprehensive income (loss) as a component ofshareholders’ equity. Translation gains or losses are not released to net income unless theassociated net investment has been sold, liquidated, or substantially liquidated.

Foreign currency transactions denominated in currencies other than the functionalcurrency are translated into the functional currency using the exchange rate prevailing onthe transactions dates. Monetary assets and liabilities denominated in foreign currenciesare translated into the functional currency using the applicable exchange rates at thebalance sheet dates. Net gains and losses resulting from foreign exchange transactions areincluded in interest and other income, net.

Foreign currency translation adjustments included in the Group’s consolidated statementsof comprehensive income for the years ended December 31, 2018, 2019 and 2020 and sixmonths ended June 30, 2020 and 2021 were a loss of $60.3 million, a loss of $19.0million, a gain of $148.5 million, a loss of $31.3 million and a gain of $29.2 millionrespectively. Net foreign currency transaction gains or losses arise from transacting in acurrency other than the functional currency of the entity and the amounts recorded wereimmaterial for each of the periods presented.

Net income per share

Basic net income per share is computed using the weighted average number of ordinaryshares outstanding during the period. Options and RSUs are not considered outstandingin computation of basic earnings per share. Diluted net income per share is computedusing the weighted average number of ordinary shares and potential ordinary sharesoutstanding during the period, which include options to purchase ordinary shares,restricted share units and conversion of the convertible debt. The computation of dilutednet income per share does not assume conversion, exercise, or contingent issuance ofsecurities that would have an anti-dilutive effect (i.e. an increase in earnings per shareamounts or a decrease in loss per share amounts) on net income per share. The Group usesthe two-class method to calculate net income per share though both classes share the samerights in dividends. Therefore, basic and diluted earnings per share are the same for bothclasses of ordinary shares.

Segment reporting

In accordance with ASC 280, Segment Reporting, the Group’s chief operating decisionmaker (“CODM”), the Chief Executive Officer, reviews the consolidated results whenmaking decisions about allocating resources and assessing performance of the Group asa whole. The Group currently operates and manages its business in two principal businesssegments globally — advertising and marketing services and value-added services.Information regarding the business segments provided to the Group’s CODM is at therevenue level and the Group currently does not allocate operating costs or assets to itssegments, as its CODM does not use such information to allocate resources or evaluatethe performance of the operating segments. As the Group’s long-lived assets aresubstantially all located in the PRC and substantially the Group’s revenues are derivedfrom within the PRC, no geographical information is presented.

Concentration of risks

Concentration of credit risk. The Group’s financial instruments that are potentiallysubject to concentrations of credit risk consist primarily of cash, cash equivalents,short-term investments and accounts receivable. In addition, with the majority of itsoperations in China, the Group is subject to RMB currency risk and the risk of remittanceof currency out of PRC, both of which have been difficult to hedge and the Group has notdone so. The Group limits its exposure to credit loss by depositing its cash and cashequivalents with financial institutions in the U.S., PRC and Hong Kong, which are amongthe largest and most respected with high ratings by international-recognized ratingagencies, that the management believes are of high credit quality. The managementperiodically reviews these institutions’ reputations, track records and reported reserves.

As of December 31, 2018, 2019 and 2020 and June 30, 2021, the Group hadapproximately $1.7 billion, $2.2 billion, $3.0 billion and $2.4 billion, respectively, in cashand bank time deposits (with terms generally up to twelve months) with large domesticbanks in China. China promulgated a Bankruptcy Law that came into effect on June 1,2007, which contains a separate article expressly stating that the State Council maypromulgate implementation measures for the bankruptcy of Chinese banks based on theBankruptcy Law. Under the Bankruptcy Law, a Chinese bank may go bankrupt. Inaddition, since China’s concession to WTO, foreign banks have been gradually permittedto operate in China and have become significant competitors to Chinese banks in manyaspects, especially since the opening of RMB business to foreign banks in late 2006.Therefore, the risk of bankruptcy on Chinese banks in which the Group holds cash andbank deposits has increased. In the event that a Chinese bank which holds the Group’sdeposits goes bankrupt, the Group is unlikely to claim its deposits back in full, since itis unlikely to be classified as a secured creditor to the bank under the PRC laws.

No other customer nor advertising agencyindividually represented 10% or more of the Group’s total revenues during the yearsended December 31, 2018, 2019 and 2020 and six months ended June 30, 2020 and 2021.Additionally, the Group’s top 10 advertising agencies contributed 26%, 28%, 32%, 33%and 38% to its total revenues for the years ended December 31, 2018, 2019 and 2020 andsix months ended June 30, 2020 and 2021, respectively.

As of December 31, 2018, 2019, 2020 and as of June 30, 2021, substantially all accountsreceivable were derived from the Group’s China operations. Excluding accountsreceivable due from Alibaba and other related parties, accounts receivable primarilyconsists of amounts due from advertising agencies and direct customers. Alibabaaccounted for 13%, 14%, 28% and 19%, of the Group’s net accounts receivables as ofDecember 31, 2018, 2019, 2020 and as of June 30, 2021, respectively.

Concentration of foreign currency risks. The majority of the Group’s operations were inRMB. As of December 31, 2018, 2019, 2020 and as of June 30, 2021, the Group’s cash,cash equivalents and short-term investments balance denominated in RMB was $950.8million, $936.9 million, $1,651.3 million and $1,451.6 million, accounting for 52%, 39%,47% and 49% of the Group’s total cash, cash equivalents and short-term investmentsbalance at the respective dates. As of December 31, 2018, 2019, 2020 and as of June 30,2021, the Group’s aggregate net accounts receivable balance (including accountsreceivable due from third parties, Alibaba and other related parties) denominated in RMBwas $368.8 million, $422.2 million $492.0 million and $631.2 million, respectively,representing almost all of its net accounts receivable balance. As of December 31, 2018,2019, 2020 and as of June 30, 2021, the Group’s current liabilities balance denominatedin RMB was $620.4 million, $744.2 million, $947.6 million and $1,064.1 million,accounting for 99%, 93%, 99% and 97% of its total current liabilities balance.Accordingly, the Group may experience economic losses and negative impacts onearnings and equity as a result of exchange rate fluctuations of the RMB against the U.S.dollars. Moreover, the Chinese government imposes controls on the convertibility of theRMB into foreign currencies and, in certain cases, the remittance of currency out of thePRC. The Group may experience difficulties in completing the administrative proceduresnecessary to remit its RMB out of the PRC and convert it into foreign currency.

The follow-on investment in Yixia Tech resulted in an aggregate investment in thecompany of $290.0 million prior to the $214.7 million impairment recognized in 2019 asdescribed below. The Group also invested $97.3 million, $91.9 million, $92.9 million and$103.9 million in companies, which were accounted for under equity method, in 2018,2019, 2020 and for the six months ended June 30, 2021, respectively.

The Group used measurement alternative for recording equity investments without readilydeterminable fair values at cost, less impairment, adjusted for subsequent observableprice changes. Based on ASU 2016-01, entities that elect the measurement alternative willreport changes in the carrying value of the equity investments in current earnings. Ifmeasurement alternative is used, changes in the carrying value of the equity investmentwill be recognized whenever there are observable price changes in orderly transactionsfor the identical or similar investment of the same issuer, and impairment charges will berecorded when any impairment indicators are noted and the fair value is lower than thecarrying value. The Group classifies the valuation techniques on investments that usesimilar identifiable transaction prices as Level 2 of fair value measurements.

5. Leases

On January 1, 2019, the Group adopted the new lease standard using the transition methodby applying the standard to all leases existing at the date of initial application. Theadoption of new leasing guidance resulted in recognition of $14.4 million of operatinglease assets and $14.9 million of leasing liabilities as of January 1, 2019, respectively, andno impact to the beginning retained earnings of the year.

The Group has operating leases primarily for office spaces in China. The determinationof whether an arrangement is or contains a lease is made at inception by evaluatingwhether the arrangement conveys the right to use an identified asset and whether theGroup obtains substantially all of the economic benefits from and has the ability to directthe use of the asset. Operating lease assets and liabilities are included in operating leaseright-of-use assets, operating lease liabilities, short-term, and operating lease liabilities,long-term on the Group’s consolidated balance sheets. The Group has chosen to notrecognize lease assets and lease liabilities for leases with a term of twelve months or lesson the consolidated balance sheets.

Operating lease right-of-use assets and operating lease liabilities are recognized based onthe present value of lease payments over the lease terms at the lease commencementdates. The Group uses its incremental borrowing rate in determining the present value oflease payments. The incremental borrowing rate is a hypothetical rate based on theGroup’s understanding of what interest the Group would pay in order to obtain aborrowing with an amount equivalent to the lease payments in a similar economicenvironment over the lease term on a collateralized basis from banks in China.

Certain lease agreements contain an option for the Group to renew a lease for a termagreed by the Group and the lessor or an option to terminate a lease earlier than thematurity dates. The Group considers these options, which may be elected at the Group’ssole discretion, in determining the lease term on a lease-by-lease basis. The Group’s leaseagreements generally do not contain any residual value guarantees or material restrictivecovenants. Certain of the Group’s leases contain free or escalating rent payment terms.The Group’s lease agreements generally contain lease and non-lease components.Non-lease components primarily include payments for maintenance and utilities. TheGroup has chosen to combine payments for non-lease components with lease paymentsand accounted them together as a single lease component. Payments under the leasearrangements are primarily fixed. However, for arrangements accounted for as a singlelease component, there may be variability in future lease payments as the amount of thenon-lease components is typically revised from one period to the next. Additionally,certain lease agreements with SINA contain variable payments, which are determinedbased on actual SINA headquarters space occupied by the Group and are expensed asincurred and not included in the operating lease assets and liabilities.

Cayman Islands

Under the current tax laws of the Cayman Islands, the Company is not subject to tax onincome or capital gain. In addition, upon payments of dividends by the Company to itsshareholders, no Cayman Islands withholding tax is required.

Hong Kong

Weibo HK is subject to 16.5% Hong Kong profit tax on its taxable income generated fromoperations in Hong Kong for the years of assessment 2017/2018, 2018/2019 and2019/2020. Commencing from the year of assessment 2018/2019, the first HK$2 millionof profits earned by entities incorporated in Hong Kong will be taxed at half the currenttax rate (i.e., 8.25%) while the remaining profits will continue to be taxed at the existing16.5% tax rate. As of December 31, 2018, 2019 and 2020, the Company’s Hong Kongsubsidiary had a net operating loss of $1.4 million, $8.9 million and $10.4 million, whichcan be carried forward indefinitely to offset future taxable income. The deferred tax assetsof Weibo HK as of December 31, 2018, 2019 and 2020 consist mainly of net operatingloss carried forward, for which a full valuation allowance was provided. The managementbelieves it is more likely than not that these assets will not be realized in the future.

China

Effective January 1, 2008, the Enterprise Income Tax Law (the “EIT Law”) in Chinaunifies the enterprise income tax rate for the entities incorporated in China at 25%, unlessthey are eligible for preferential tax treatment. Preferential tax treatments will be grantedto companies conducting businesses in certain encouraged sectors and to entities qualifiedas “software enterprises”, “key software enterprises” (“KSE”) and/or “high and newtechnology enterprise” (“HNTE”). Weibo Technology, the Group’s WFOE, was qualifiedas a “software enterprise” and was entitled to an exemption from the enterprise incometax for two years beginning 2015, its first accumulative profitable year, and a 50%reduction to a tax rate of 12.5% for the subsequent three years (2017-2019). AlthoughWeibo Technology was qualified as a “software enterprise” in 2020, it will not enjoy areduced tax rate for its “software enterprise” status as it has been five years since its firstprofitable year of 2015. Weibo Technology completed its filings as a “key softwareenterprise” with the tax authority in 2018, 2019, and 2020 for its status of 2017, 2018 and2019, respectively, therefore was entitled to enjoy a further reduced preferential tax rateof 10% for 2017, 2018 and 2019. The qualification as a KSE is subject to annualevaluation and approval by the relevant authorities in China and the Group will onlyrecognize the preferential tax treatment of KSE status when approval from the relevantauthorities is obtained, usually one year in arrears. Weibo Technology was also grantedthe HNTEs status for the fiscal years from 2017 to 2022, which entitled the qualifiedentity a preferential tax rate of 15% in 2020 and 2021. Its qualification as a HNTE issubject to annual evaluation and a three-year review by the relevant authorities in China.In addition, certain of the Group’s other PRC entities are also qualified as a “softwareenterprises”, and/or HNTE, and currently enjoy the respective preferential tax treatments.

China (continued)

The EIT Law also provides that an enterprise established under the laws of a foreigncountry or region but whose “de facto management body” is located in the PRC be treatedas a resident enterprise for PRC tax purposes and consequently be subject to the PRCincome tax at the rate of 25% for its global income. The Implementing Rules of the EITLaw merely define the location of the “de facto management body” as “the place wherethe exercising, in substance, of the overall management and control of the production andbusiness operation, personnel, accounting, properties, etc., of a non-PRC company islocated.” Based on a review of surrounding facts and circumstances, the Group does notbelieve that it is likely that its operations outside of the PRC be considered a residententerprise for PRC tax purposes. However, due to limited guidance and implementationhistory of the EIT Law, should Weibo be treated as a resident enterprise for PRC taxpurposes, the Company will be subject to PRC tax on worldwide income at a uniform taxrate of 25% retroactive to January 1, 2008.

The EIT Law also imposes a withholding income tax rate of 10% on dividends distributedby a WFOE to its immediate holding company outside of China, if such immediateholding company is considered as a non-resident enterprise without any establishment orplace within China or if the received dividends have no connection with the establishmentor place of such immediate holding company within China, unless such immediateholding company’s jurisdiction of incorporation has a tax treaty with China that providesfor a different withholding arrangement. The Cayman Islands, where the Companyincorporated, does not have such tax treaty with China. According to the arrangementbetween Mainland China and Hong Kong Special Administrative Region on theAvoidance of Double Taxation and Prevention of Fiscal Evasion in August 2006,dividends paid by a WFOE in China to its immediate holding company in Hong Kong willbe subject to withholding tax at a rate of no more than 5% (if the foreign investor ownsdirectly at least 25% of the shares of the WFOE). The State Administration of Taxationfurther promulgated Circular 601 on October 27, 2009, which provides that tax treatybenefits will be denied to “conduit” or shell companies without business substance andthat a beneficial ownership analysis will be used based on a “substance-over-form”principle to determine whether or not to grant the tax treaty benefits.

The operations of the Group’s WFOE in China are invested and held by Weibo HK. If theCompany is regarded as a non-resident enterprise and Weibo HK is regarded as a residententerprise, then Weibo HK may be required to pay a 10% withholding tax on anydividends payable to the Company. If Weibo HK is regarded as a non-resident enterprise,then Weibo Technology may be required to pay a 5% withholding tax for any dividendspayable to Weibo HK. However, it is still unclear at this stage whether Circular 601applies to dividends from Weibo Technology paid to Weibo HK. If Weibo HK were notconsidered as “beneficial owners” of any dividends from Weibo Technology, thedividends payable to Weibo HK would be subject to a withholding tax of 10%. Thecurrent policy approved by the Company’s board of directors allows the Group todistribute PRC earnings offshore only if the Group does not have to pay a dividend tax.As of December 31, 2018, 2019 and 2020 and June 30, 2021, the Group did not recordany withholding tax for its PRC subsidiaries.

The provision for income taxes for China operations for the years ended December 31,2018, 2019 and 2020 differs from the amounts computed by applying the statutory EITrate primarily due to the preferential tax treatments described above enjoyed by theWFOE, Weibo Technology, during the periods presented. For the years ended December31, 2018 and 2019, Weibo Technology enjoyed a tax reduction of $77.2 million and $83.2million due to the preferential tax treatment of being a qualified software enterprise. Italso enjoyed a tax reduction of $55.1 million for the HNTE status in 2020. The WFOEfurther recognized preferential tax treatment of “key software enterprise” status and taxbenefit of research and development super deduction of $11.7 million for 2017 in 2018,$21.5 million for 2018 in 2019, and $26.6 million for 2019 in 2020. The Group did notrecognize these tax benefits in the corresponding year as they were uncertain, and onlyrecorded them on a lag basis when the tax benefits become more-likely-than-not to besustained in the next year. The preferential tax treatments benefited by the Group duringthe three-year period ended December 31, 2020 resulted in an effect of $0.39, $0.43 and$0.40 on basic net income per share in 2018, 2019 and 2020, respectively.

Valuation allowance is provided against deferred tax assets when the Group determinesthat it is more likely than not that the deferred tax assets will not be utilized in the future.In making such determination, the Group considered factors including (i) future reversalsof existing taxable temporary differences; (ii) future taxable income exclusive ofreversing temporary differences and carry forwards; and (iii) tax planning strategies. Thevaluation allowance on deferred tax assets as of December 31, 2018, 2019, 2020 and June30, 2021 was $17.6 million, $32.0 million, $89.7 million and $90.9 million, respectively.The change in valuation allowance was primarily due to bad debt expenses andinvestment impairment charges/fair value change of investments. Historically, deferredtax assets were valued using the statutory rate of 25% for China operations. As ofDecember 31, 2018, 2019 and 2020, the Group had net operating loss carry forwards forChina operations totaling $16.7 million, $22.1 million and $30.1 million, respectively, forwhich full valuation allowance was provided as the Group anticipates that it is more likelythan not that these net operating losses may not be utilized based on its estimate of theoperation performance of these PRC entities. Net operating loss carry forwards for Chinaoperations as of December 31, 2020 will expire, if unused, in the years ending December31, 2021 through December 31, 2025.

Uncertain tax position

Except for the lag recognitions of preferential tax treatment of KSE status, research anddevelopment super deduction and stock based related deduction, the Group did not recordany liability or decrease in deferred tax asset related to uncertain tax positions as ofDecember 31, 2018, 2019, 2020 and June 30, 2021, and thus, no interest and penaltiesrelated to uncertain tax positions were recorded.

For the six months ended June 30, 2021, based on interactions with the tax authorities,the Group received additional guidance regarding certain areas with heightenedrequirements, and updated its estimate of related tax benefit amount that is expected tobe sustained upon settlement with tax authorities. Additional $27.9 million tax liabilityrelated to uncertain tax positions was recognized for the six months ended June 30, 2021,which is based on the updated estimate of the largest amount of tax benefit that is greaterthan 50% likely to be realized upon settlement with the tax authorities. It is possible thatthe estimate and ultimate resolution of these uncertain tax positions may further changebased on further interactions with the tax authorities.

In general, the PRC tax authorities have up to five years to review a company’s tax filings.Accordingly, tax filings of the Company’s PRC subsidiaries and VIEs for tax years 2016through 2020 remain subject to the review by the relevant PRC tax authorities.

Recurring

The Group measures short-term investments and equity securities with readilydeterminable fair values on a recurring basis. The fair value of the Group’s equitysecurities with readily determinable fair values are determined based on the quotedmarket price (Level 1). The fair value of the Group’s short-term investments aredetermined based on the quoted market price for similar products (Level 2).

Non-recurring

For those equity investments without readily determinable fair value, the Group measuresthem at market value when observable price changes are identified or impairment chargewere recognized. The market values of the Group’s privately held investments asdisclosed are determined based on the discounted cash flow model using the discountcurve of market interest rates or based on the similar transaction price in the marketdirectly. The Group classifies the valuation techniques on those investments that usesimilar identifiable transaction prices as Level 2 of fair value measurements. The Groupmeasures equity method investments at fair value on a non-recurring basis only if animpairment charge is recognized.

The fair value of the privately held investments was measured eitherbased on discounted cash flow with unobservable inputs including the discount curve ofmarket interest rates, which ranged from 12% to 23%, or based on comparing theoperating metrics of public peer companies with the investees.

The Group’s non-financial assets, such as intangible assets, goodwill, fixed assets andoperating lease assets, are measured at fair value only if they were determined to beimpaired. In accordance with the Group’s policy to perform an impairment assessment ofits goodwill on an annual basis as of the balance sheet date or when facts andcircumstances warrant a review, the Group performed an impairment assessment on itsgoodwill by reporting unit annually. The Group recognized impairment charge ofgoodwill arising from previous acquisitions of $10.6 million, nil, nil, nil and nil for theyears ended December 31, 2018, 2019, 2020 and six months ended June 30, 2020 and2021, respectively.

The carrying amount of cash and cash equivalents, short-term investments, accountsreceivable due from third parties, accounts receivable due from Alibaba, accountsreceivable due from other related parties, amount due from SINA, accounts payable,accrued and other liabilities approximates fair value because of their short-term nature.

There are uncertainties regarding the legal basis of the Group’s ability to operate anInternet business in China. Although China has implemented a wide range of market-oriented economic reforms, the telecommunication, information and media industriesremain highly regulated. Not only are such restrictions currently in place, the existingregulations are unclear as to which specific segments of these industries companies withforeign investors, including the Company, may operate. Therefore, the Group may berequired to limit the scope of its operations in China, and this could have a materialadverse effect on its financial position, results of operations and cash flows.

There are no claims, lawsuits, investigations or proceedings, including unasserted claimsthat are probable to be assessed, that have in the recent past had, or to the Group’sknowledge, are reasonably possible to have, a material impact on the Group’s financialstatements.

18. Redeemable Non-controlling Interests

In the fourth quarter of 2020, the Group entered into a series of share purchaseagreements with then existing shareholders of JM Tech to acquire the majority of thecompany’s equity interest (Note 6). The Group agreed to redeem the non-controllinginterests held by founder and CEO of the company under certain circumstances during thefollowing years subsequent to the acquisition. The Group determined that the non-controlling interest with redemption rights should be classified as redeemable non-controlling interest since they are contingently redeemable upon the occurrence of certainconditional events, which are not solely within the control of the Group.

The redeemable non-controlling interests is recognized at fair value on the acquisitiondate. The Group records accretion on the redeemable non-controlling interest to theredemption value over the period from the date of the acquisition to the date of earliestredemption. The accretion using the effective interest method, is recorded as deemeddividends to preferred shareholders, which reduce retained earnings and equity classifiednon-controlling interests, and earnings available to common shareholders in calculatingbasic and diluted earnings per share.

The process of adjusting redeemable non-controlling interests to its redemption value (the“Mezzanine Adjustment”) should be performed after attribution of the subsidiary’s netincome or loss pursuant to ASC 810, Consolidation. The carrying amount of redeemablenon-controlling interests will equal the higher of the amount resulting from application ofASC 810 or the amount resulting from the Mezzanine Adjustment. As the expectedredemption value is less than the carrying value of redeemable non-controlling interests,there is nil and nil mezzanine adjustment recognized for the year ended December 31,2020 and six months ended June 30, 2021, respectively.

Pursuant to the agreements between the Group and the founders who are also employeesof JM Tech, the founders are required to be in employment during the following two yearstill December 31, 2022 to be entitled to their proportionate share in JM Tech’s existingand future retained earnings during the period. Such entitlement will automatically beforfeited upon the termination of their employment during the period. The Companyconsidered this arrangement as certain economic interests associated with the founders’non-controlling interest in JM Tech till December 31, 2022. Therefore, the Companyrecognized compensation costs for the founders’ share of JM Tech’s retained earningswith the credit increasing non-controlling interest and redeemable non-controllinginterest. During the six months ended June 30, 2021, $13.3 million compensation costswere recognized, of which $10.9 million was recorded to increase redeemable non-controlling interest.

19. Subsequent events

From June 30, 2021 to the date of publication of this report, there was no subsequentevent which had a material impact on the Group.

Cash paymentfor billings from SINA for costs and expenses allocated to the Group is presented underoperating activities in the unaudited interim condensed consolidated statements of cashflows. The Group’s unaudited interim condensed consolidated statements ofcomprehensive income contain all the related costs and expenses of the Weibo business,including allocation to the cost of revenues, sales and marketing expenses, productdevelopment expenses, and general and administrative expenses, which are incurred bySINA but related to the Weibo business.

Consolidation

The unaudited interim condensed consolidated financial statements include the accountsof the Company, its wholly-owned subsidiaries, VIEs, of which the Company is theprimary beneficiary, and VIEs’ subsidiaries. All significant intercompany balances andtransactions have been eliminated.

To comply with PRC laws and regulations, the Group provides a substantial amount of itsservices in China via the VIEs, which hold critical operating licenses that enable theGroup to do business in China. Most of the Group’s revenues, costs and expense, and netincome in China were generated directly or indirectly through the VIEs. The Company,through the WFOE, has signed various agreements with the VIEs to allow the transfer ofeconomic benefits from the VIEs to the Company. The Group has determined that it is theprimary beneficiary of the VIEs through Weibo Technology’s contractual arrangementswith the VIEs. Accordingly, the Company has consolidated the VIEs’ results of operationsand assets and liabilities in the Group’s financial statements pursuant to the United StatesGenerally Accepted Accounting Principles (“US GAAP”) for all the periods presented.

Shareholders of the VIEs are certain nominee shareholders from the Company or SINA.The capital for their investments in the VIEs is funded by the Company and recorded asinterest-free loans to these individuals. These loans were eliminated with the capital ofthe VIEs during consolidation. Each shareholder of the VIEs has agreed to transfer theirequity interest in the VIEs to Weibo Technology when permitted by PRC laws andregulations or to designees of the Company at any time for the amount of loansoutstanding. All voting rights of the VIEs, including without limitation the right toappoint all directors of the VIEs, has been assigned to Weibo Technology. WeiboTechnology has also entered into exclusive technical service agreements with the VIEsunder which Weibo Technology provides technical and other services to the VIEs inexchange for substantially all net income of the VIEs. In addition, the shareholders of theVIEs have pledged their shares in the VIEs as collateral for the non-payment of loans orfor the technical and other services fees due to Weibo Technology. As of December 31,2020 and September 30, 2021, the total amounts of interest-free loans to the VIEs’shareholders were $89.5 million and $90.7 million, respectively. The VIEs and VIEs’subsidiaries had accumulated deficit of $96.1 million and $186.1 million as of December31, 2020 and September 30, 2021, respectively, which were included in the Group’sunaudited interim condensed consolidated financial statements.

Under the contractual arrangements with the VIEs, the Company has the power to directactivities of the VIEs through Weibo Technology and can have assets transferred freelyout of the VIEs without restrictions. Therefore, the Company considers that there is noasset of the VIEs that can only be used to settle obligations of the VIEs and VIEs’subsidiaries, except for the registered capital and non-distributable reserve funds of theVIEs and VIEs’ subsidiaries, amounting to $196.6 million and $228.8 million as ofDecember 31, 2020 and September 30, 2021, respectively. Since the VIEs areincorporated as limited liability companies under the PRC Company Law, creditors of theVIEs do not have recourse to the general credit of the Company. There is currently nocontractual arrangement that would require the Company to provide additional financialsupport to the VIEs. As the Company is conducting certain businesses mainly through theVIEs, the Company may provide such support on a discretionary basis in the future,which could expose the Company to a loss. The total amount of costs and expensesallocated from SINA to the VIEs was $7.0 million and $2.6 million for the nine monthsended September 30, 2020 and 2021, respectively.

Minority Investment in Weimeng

In April 2020, WangTouTongDa (Beijing) Technology Co., Ltd., an entity affiliated withZhongWangTou (Beijing) Technology Co., Ltd., made an investment of approximatelyRMB10.7 million in Weimeng for 1% of Weimeng’s enlarged registered capital. Suchthird party minority stake holder is entitled to customary economic rights in proportionto its equity ownership, and certain minority shareholder rights such as the right toappoint a director to Weimeng’s three-member board of directors, and veto rights overcertain matters related to content decision, and certain future financings of Weimeng.

The third party minority stake holder is not a party to the contractual arrangementsmentioned above that are currently in effect among Weimeng, Weibo Technology andWeimeng’s other shareholders. As such, despite the fact that the Company is still able toenjoy economic benefits and exercise effective control over Weimeng and its subsidiaries,the Company is not able to purchase or have the third party minority stake holder pledgeits 1% equity interests in Weimeng in the same manner as agreed under existingcontractual arrangements, nor is it granted the authorization of voting rights over these1% equity interests. The Company believes Weibo Technology, the wholly-owned PRCsubsidiary, still controls and is the primary beneficiary of Weimeng as it continues to havea controlling financial interest in Weimeng pursuant to ASC 810-10-25-38A after theissuance of such 1% equity interests.

The Company believes that the contractual arrangements among the WFOE, VIEs andVIEs’ shareholders are in compliance with the current PRC laws and legally enforceable.However, uncertainties in the interpretation and enforcement of the PRC laws, regulationsand policies could limit the Company’s ability to enforce these contractual arrangements.As a result, the Company may be unable to consolidate the VIEs and VIEs’ subsidiariesin the consolidated financial statements. The Company’s ability to control the VIEs alsodepends on the authorization by the shareholders of the VIEs to exercise voting rights onall matters requiring shareholder approval in the VIEs. The Company believes that theagreements on authorization to exercise shareholder’s voting power are legallyenforceable. In addition, if the legal structure and contractual arrangements with the VIEswere found to be in violation of any future PRC laws and regulations, the Company maybe subject to fines or other actions. The Company believes the possibility that it will nolonger be able to control and consolidate the VIEs as a result of the aforementioned risksand uncertainties is remote.

2. Significant Accounting Policies

Basis of presentation

The preparation of the Group’s unaudited interim condensed consolidated financialstatements is in conformity with U.S. GAAP. The unaudited interim condensedconsolidated financial statements include the accounts of Weibo, its wholly ownedsubsidiaries, VIEs, and VIEs’ subsidiaries. All significant intercompany balances andtransactions have been eliminated.

The unaudited interim condensed consolidated financial statements have been preparedon the same basis as the audited consolidated financial statements. In the opinion of theCompany, the accompanying unaudited interim condensed consolidated financialstatements contain all adjustments, consisting of only normal recurring adjustments,necessary for a fair statement of its financial position as of September 30, 2021, its resultsof operations and cash flows for the nine months ended September 30, 2020 and 2021.The unaudited interim condensed consolidated balance sheet as of December 31, 2020,was derived from audited financial statements as of that date, but does not contain all ofthe footnote disclosures required by U.S. GAAP for a complete set of financialstatements. Accordingly, these financial statements should be read in conjunction with theaudited consolidated financial statements and related footnotes for the year endedDecember 31, 2020.

Use of estimates

Conformity with U.S. GAAP requires the use of estimates and judgments that affect thereported amounts in the unaudited interim condensed consolidated financial statementsand accompanying notes. These estimates form the basis for judgments the managementmakes about the carrying values of the assets and liabilities, which are not readilyapparent from other sources. U.S. GAAP requires making estimates and judgments inseveral areas, including, but not limited to, the basis of consolidation, revenuerecognition, fair value accounting, income taxes, long-term investments, goodwill andother long-lived assets, allowances for credit losses, stock-based compensation, theestimated useful lives of assets, convertible debt, business combination, and foreigncurrency. The management bases the estimates and judgments on historical informationand on various other assumptions that management believes are reasonable under thecircumstances. Actual results could differ materially from such estimates.

Revenue recognition

Under ASC 606, revenues are recognized when control of the promised goods or servicesis transferred to customers, in an amount that reflects the consideration the Group expectsto be entitled to in exchange for those goods or services. The Group identifies its contractswith customers and all performance obligations within those contracts. The Group thendetermines the transaction price and allocates the transaction price to the performanceobligations within the Group’s contracts with customers, recognizing revenue when, or as,the Group satisfies its performance obligations.

Revenue recognition (continued)

The Group does not believe that significant management judgments are involved inrevenue recognition, but the amount and timing of the Group’s revenues could bedifferent for any period if management made different judgments. Certain customers mayreceive sales rebates, which are accounted for as variable consideration. The Groupestimates annual expected revenue volume of each individual agent with reference to theirhistorical results. The Group recognizes revenue for the amount of fees it receives fromits advertisers, after deducting estimated sales rebates and net of value-added tax (“VAT”)under ASC 606. The Group believes that there will not be significant changes to itsestimates of variable consideration.

Revenue disaggregated by revenue source for the nine months ended September 30, 2020and 2021 consists of the following:

Nine Months EndedSeptember 30,

2020 2021

(In thousands)

Advertising and marketing revenues $1,032,678 $1,429,969Value-added services revenues 143,843 210,827

Total revenues $1,176,521 $1,640,796

The Group enters into contracts with its customers, which may give rise to contract assets(unbilled revenue) or contract liabilities (deferred revenue). The payment terms andconditions within the Group’s contracts vary by the type and location of its customers andproducts or services purchased, the substantial majority of which are due in less than oneyear. Deferred revenues related to unsatisfied performance obligations at the end of theperiod are mainly from the customer advance of the advertising and marketing servicesand the sales of the fee-based services, such as VIP membership, live streaming, andvirtual currency or in-game virtual items sold for game related services. The deferredrevenues are recognized based on customers’ consumption or amortized on a straight-linebasis through the service period for different products/services. Due to the generallyshort-term duration of the contracts, the majority of the performance obligations aresatisfied in the following reporting period. The amount of revenue recognized that wasincluded in the deferred revenue balance at the beginning of the period was $120.1million for the nine months ended September 30, 2021.

Practical Expedients and Exemptions

The Group generally expenses sales commissions when incurred because the amortizationperiod is generally one year or less. These costs are recorded within sales and marketingexpenses.

Revenue recognition (continued)

Advertising and marketing revenues

Advertising and marketing revenues are derived principally from online advertising,including social display ads and promoted marketing. Social display ad arrangementsallow customers to place advertisements on particular areas of the Group’s platform orwebsite in particular formats and over particular periods of time, which is typically nomore than three months. The Group enters into cost per mille (“CPM”), or cost perthousand impressions, advertising arrangements with the customers, under which theGroup recognizes revenues based on the number of times that the advertisement has beendisplayed. The Group also enters into cost per day (“CPD”) advertising arrangements withcustomers, under which the Group recognizes revenues ratably over the contract periods.Promoted marketing arrangements are primarily priced based on CPM. Under the CPMmodel, customers are obligated to pay when the advertisement is displayed.

The Group’s majority revenue transactions are based on standard business terms andconditions, which are recognized net of agency rebates. The agency rebates are accountedfor as variable consideration and are estimated during interim periods based on estimatedannual revenue volume of each individual agent with reference to their historical results,which involves accounting judgment. The Group believes its estimation approach invariable consideration results in revenue recognition in a manner consistent with theunderlying economics of the transaction.

The Group’s contracts with customers may include multiple performance obligations,which primarily consist of combinations of service to allow customers to placeadvertisements on different areas of its platform or website. For such arrangements,advertising arrangements involving multiple deliverables are broken down into single-element arrangements based on their stand-alone selling price for revenue recognitionpurposes. The estimation of stand-alone selling price involves significant judgment,especially for the deliverables that have not been sold separately. For those deliverables,the Group determines best estimate of the stand-alone selling price by taking intoconsideration of the pricing of advertising areas of the Group’s platform or website withsimilar popularities and advertisements with similar formats and quoted prices fromcompetitors and other market conditions. The Group believes the estimation approach instand-alone selling price and allocation of the transaction price on a relative stand-aloneselling price to each performance obligation results in revenue recognition in a mannerconsistent with the underlying economics of the transaction and the allocation principleincluded in ASC 606. Revenues recognized with reference to best estimation of sellingprice were immaterial for all periods presented. Most of such contracts have allperformance obligations completed within one year. Changes in judgments on theseassumptions and estimates could materially impact the timing or amount of revenuerecognition. Contracts with customers of online advertising may require cooperation fromthird parties. The Group pays a predetermined portion of revenues earned fromadvertising contracts to the third parties such as key opinion leaders who participate inadvertising and promotion activities by monetizing their social assets. The Group hasdetermined that it is the principal in these transactions, as it has primary responsibility forfulfilling all the obligations related to advertising contracts. The Group has discretion inestablishing pricing of the contracts and controls the advertising inventory before thedelivery to customers. The Group records revenues derived from such contracts on a grossbasis and the portion paid to the third parties is recognized as cost of revenues.

Value-added services revenues

The Group generates value-added services revenues principally from fee-based services,mainly including VIP membership, live streaming, and game-related services. Othervalue-added services revenues mainly include the revenues from the provision of trafficacquisition services to various customers. Revenues from these services are recognizedwhen control of the promised services is transferred to customers, in an amount thatreflects the consideration the Group expects to be entitled to in exchange for thoseservices.

VIP membership. VIP membership mainly includes a service package consisting of oneperformance obligation of providing user certification and preferential benefits, such asdaily priority listings and higher quota for following user accounts. Prepaid VIPmembership fees are recorded as deferred revenue and recognized as revenue ratably overthe contract period of the membership service.

Live streaming. Live streaming generates revenue from sales of virtual items on thelive-streaming platform (“Yizhibo”). Users can access the platform and view the livestreaming content and interact with the broadcasters for free.

The Group designs, creates and offers various virtual items for sales to users withpre-determined selling prices. Each virtual item is considered as a distinctive performanceobligation. Sales proceeds are recorded as deferred revenue and recognized as revenuebased on the consumption of the virtual items. Users can purchase and present virtualitems to broadcasters to show support for their favorite ones. Under the arrangementswith broadcasters or broadcaster agencies, the Group shares with them a portion of therevenues derived from the consumption of virtual items. Revenues derived from the saleof virtual items are recorded on a gross basis as the Group has determined that it acts asthe principal to fulfill all obligations related to the live streaming services. The portionpaid to broadcasters and/or broadcaster agencies is recognized as cost of revenues. TheGroup does not have further obligations to the user after the virtual items are consumed.

Game-related services. Game-related service revenues are mostly generated from thepurchase of virtual items by game players through the Group’s platform, including items,avatars, skills, privileges or other in game consumables, features or functionality, withinthe games. The Group’s performance obligation is to provide on-going game services toplayers who purchased virtual items to gain an enhanced game-playing experience. Eachvirtual item is considered as a distinctive performance obligation. The Group collects

payments from the game players in connection with the sale of virtual currency, whichcan be used to purchase virtual items in online games. For games co-operated with thirdparty developers, revenue is recorded on a gross basis for games that the Group is actingas the principal in fulfilling all obligations related to the games and revenue is recordednet of predetermined revenue sharing with the game developers for games in which theGroup is not acting as the principal in fulfilling all obligations. Sales of virtual currenciesare recognized as revenues over the estimated lifespans of in-game virtual items. Theestimated lifespans of different virtual items are determined by the management based oneither the expected user relationship periods or the stipulated period of validity of therelevant virtual items depending on the respective term of virtual items. Virtual currencysold for game-related services in excess of recognized revenues is recorded as deferredrevenues.

Cost of revenues

Cost of revenues consists mainly of costs associated with the maintenance of platform,which primarily include bandwidth and other infrastructure costs, revenue-share cost,advertisement production cost, labor cost and turnover taxes levied on the revenues, partof which were allocated from SINA. The Group is subject to 3% cultural businessconstruction fees for its advertising and marketing revenues, which is included in cost ofrevenues. Starting from July 1 2019, the 3% cultural business construction fees wasreduced to 1.5%. Moreover, as part of the measures taken by the government to ease thenegative impact from Covid-19 pandemic, the cultural business construction fees wereexempted for the fiscal years of 2020 and 2021. An aggregate of $15.7 million and $18.8million cultural business construction fees was exempted for the nine months endedSeptember 30, 2020 and 2021, respectively.

Sales and marketing expenses

Sales and marketing expenses consist mainly of online and offline advertising andpromotional expenses, salary, benefits and commission expenses, and facility expenses.Advertising and promotional expenses generally represent the expenses of promotions ofcorporate image and product marketing. The Group expenses all advertising andpromotional expenses as incurred and classifies these expenses under sales and marketingexpenses. Pursuant to the adoption of ASC 606, the recognition of revenues and expensesat fair value for advertising barter transactions has resulted in an increase of revenue andadvertising expenses. For the nine months ended September 30, 2020 and 2021, theadvertising and promotional expenses were $230.3 million and $312.9 million,respectively.

Product development expenses

Product development expenses consist mainly of payroll-related expenses andinfrastructure costs incurred for enhancement to and maintenance of the Group’splatform, as well as costs associated with new product development and productenhancements, part of which were allocated from SINA. The Group expenses all costsincurred for the planning, post implementation phases of development and costsassociated with repair or maintenance of the existing site or the development of platformcontent. Since inception, the amount of costs qualifying for capitalization has beenimmaterial and, as a result, all product development costs have been expensed asincurred.

Stock-based compensation

All stock-based awards to employees and directors, such as stock options and restrictedshare units (“RSUs”), are measured at the grant date based on the fair value of the awards.Stock-based compensation, net of forfeitures, is recognized as expense on a straight-linebasis over the requisite service period, which is the vesting period.

The Group uses the Black-Scholes option pricing model to estimate the fair value of stockoptions. The determination of estimated fair value of stock-based payment awards on thegrant date using an option pricing model is affected by the fair value of the Company’sordinary shares as well as assumptions regarding a number of complex and subjectivevariables. These variables include the expected value volatility of the Company over theexpected term of the awards, actual and projected employee stock option exercisebehaviors, a risk-free interest rate and expected dividends, if any. Options grantedgenerally vest over four years.

The Group recognizes the estimated compensation cost of restricted share units based onthe fair value of its ordinary shares on the date of the grant. The Group recognizes thecompensation cost, net of estimated forfeitures, over a vesting term of generally fouryears for service-based restricted share units. The Group also recognizes thecompensation cost of performance-based restricted share units, net of estimatedforfeitures, if it is probable that the performance condition will be achieved at the end ofeach reporting period.

Forfeitures are estimated at the time of grant and revised in subsequent periods if actualforfeitures differ from those estimates. The Group uses historical data to estimatepre-vesting option and records stock-based compensation expense only for those awardsthat are expected to vest. See Note 7 Stock-based Compensation for further discussion onstock-based compensation.

Taxation

Income taxes. Income taxes are accounted for using the asset and liability approach.Under this approach, income tax expense is recognized for the amount of taxes payableor refundable for the current year. In addition, deferred tax assets and liabilities arerecognized for expected future tax consequences of temporary differences between thefinancial reporting and tax bases of assets and liabilities, and for operating losses and taxcredit carry forwards. The Group records a valuation allowance to reduce deferred taxassets to an amount for which realization is more likely than not.

Uncertain tax positions. To assess uncertain tax positions, the Group applies a more likelythan not threshold and a two-step approach for the tax position measurement and financialstatement recognition. Under the two-step approach, the first step is to evaluate the taxposition for recognition by determining if the weight of available evidence indicates thatit is more likely than not that the position will be sustained, including resolution of relatedappeals or litigation processes, if any. The second step is to measure the tax benefit as thelargest amount that is more than 50% likely of being realized upon settlement.

Short-term investments

Short-term investments represent bank time deposits and wealth management productswhich are certain deposits with variable interest rates or principal not-guaranteed withcertain financial institutions. Their original maturities are of greater than three months butless than one year. In accordance with ASC 825, Financial Instruments, for wealthmanagement products with the interest rate indexed to performance of underlying assets,the Group elected the fair value method at the date of initial recognition and carried theseinvestments at fair value. Changes in the fair value are reflected in the unaudited interimcondensed consolidated statements of comprehensive income as interest income.

Credit losses

In 2016, the FASB issued ASC Topic 326, which amends previously issued guidanceregarding the impairment of financial instruments by creating an impairment model thatis based on expected losses. The guidance is applicable to accounts receivable and theGroup adopted ASC Topic 326 on January 1, 2020. Accounts receivable are recorded atthe original amounts less an allowance for any potential uncollectible amounts. TheGroup makes estimates of expected credit and collectability trends for the allowance forcredit losses based upon assessment of various factors, including historical experience,the age of the accounts receivable balances, credit-worthiness of the customers, currenteconomic conditions, reasonable and supportable forecasts of future economic conditions,and other factors that may affect its ability to collect from the customers. The Group alsoprovides specific provisions for allowance when facts and circumstances indicate that thereceivable is unlikely to be collected. Expected credit losses for accounts receivable arerecorded as general and administrative expenses on the unaudited interim condensedconsolidated statements of comprehensive income. The initial impact of applying ASCTopic 326 on the consolidated financial statements is immaterial to the Group’s retainedearnings as of January 1, 2020.

Credit losses (continued)

ASC Topic 326 is also applicable to the loans to and interest receivable from other relatedparties included in the prepaid expenses and other current assets on the unaudited interimcondensed consolidated balance sheets. Management estimates the allowance for creditlosses on loans and interest receivable not sharing similar risk characteristic on anindividual basis, based on lifetime expected credit losses of these loans and interestreceivable by estimating loan collection schedule, then discounting these cash flows totheir present values. The key factors considered when determining the above allowancesfor credit losses include estimated loan collection schedule, discount rate, financialcondition and performance data of the borrowers and reasonable and supportableperformance forecasts.

Fair value measurements

Financial instruments

All financial assets and liabilities are recognized or disclosed at fair value in theunaudited interim condensed consolidated financial statements on a recurring basis.Accounting guidance defines fair value as the price that would be received from sellingan asset or paid to transfer a liability in an orderly transaction between marketparticipants at the measurement date. When determining the fair value measurements forassets and liabilities required or permitted to be recorded at fair value, the Groupconsiders the principal or most advantageous market in which it would transact and itconsiders assumptions that market participants would use when pricing the asset orliability.

The Group measures the equity method investments at fair value on a non-recurring basisonly if an impairment charge were to be recognized. For those investments withoutreadily determinable fair value, the Group measures them at fair value when observableprice changes are identified or impairment charge was recognized. The fair values of theGroup’s privately held investments as disclosed are determined based on the discountedcash flow model using the discount curve of market interest rates or based on the similartransaction price in the market directly. The fair values of the Group’s long-terminvestments in the equity securities of publicly listed companies are measured usingquoted market prices. The Group’s non-financial assets, such as intangible assets,goodwill, fixed assets and operating lease assets, are measured at fair value only if theyare determined to be impaired.

Fair value measurements (continued)

Financial instruments (continued)

Accounting guidance establishes a fair value hierarchy that requires an entity to maximizethe use of observable inputs and minimize the use of unobservable inputs when measuringfair value. A financial instrument’s categorization within the fair value hierarchy is basedupon the lowest level of input that is significant to the fair value measurement.Accounting guidance establishes three levels of inputs that may be used to measure fairvalue:

• Level 1 applies to assets or liabilities for which there are quoted prices in activemarkets for identical assets or liabilities.

• Level 2 applies to assets or liabilities for which there are inputs other than quotedprices included within Level 1 that are observable for the asset or liability such asquoted prices for similar assets or liabilities in active markets; quoted prices foridentical asset or liabilities in markets with insufficient volume or infrequenttransactions (less active markets); or model-derived valuations in which significantinputs are observable or can be derived principally from, or corroborated by,observable market data.

• Level 3 applies to asset or liabilities for which there are unobservable inputs to thevaluation methodology that are significant to the measurement of the fair value ofthe assets or liabilities.

The carrying amount of cash and cash equivalents, short-term investments, accountsreceivable due from third parties, accounts receivable due from Alibaba, accountsreceivable due from other related parties, amount due from SINA, accounts payable,accrued and other liabilities approximates fair value because of their short-term nature.See Note 15 Fair Value Measurement for additional information.

Long-term investments

Long-term investments are comprised of investments in publicly traded companies,privately held companies, and limited partnerships. The Group uses the equity method toaccount for ordinary-share-equivalent equity investments on which it has significantinfluence but does not own a majority equity interest or otherwise control.

Long-term investments (continued)

The Group measures investments in equity securities, other than equity methodinvestments, at fair value through earnings. For those investments without readilydeterminable fair values, the Group elects to record these investments at cost, lessimpairment, plus or minus subsequent adjustments for observable price changes. Underthis measurement alternative, changes in the carrying value of the investments will berecognized in unaudited interim condensed consolidated statement of comprehensiveincome, whenever there are observable price changes in orderly transactions for theidentical or similar investment of the same issuer.

Pursuant to ASC 321, for equity investments measured at fair value with changes in fairvalue recorded in earnings, the Group does not assess whether those securities areimpaired. For equity investments without readily determinable fair value for which theGroup has elected to use the measurement alternative, the Group makes a qualitativeassessment of whether the investment is impaired at each reporting date, applyingsignificant judgement in considering various factors and events including a) adverseperformance of investees; b) adverse industry developments affecting investees; and c)adverse regulatory, social, economic or other developments affecting investees. If aqualitative assessment indicates that the investment is impaired, the Group estimates theinvestment’s fair value in accordance with the principles of ASC 820. If the fair value isless than the investment’s carrying value, the Group recognizes an impairment loss in netincome equal to the difference between the carrying value and fair value. Significantjudgement is applied by the Group in estimating the fair value to determine if animpairment exists, and if so, to measure the impairment losses for these equity securityinvestments. These judgements include the selection of valuation methods in estimatingfair value and the determination of key valuation assumptions used, including cash flowforecasts and critical assumptions used in cash flow forecasts, such as the investees’revenue growth rate, terminal growth rate, discount rate, selection of comparablecompanies and multiples, estimated volatility rate and discount for lack of marketability.

Investments in entities which the Group can exercise significant influence and holds aninvestment in voting common shares or in-substance common shares (or both) of theinvestee but does not own a majority equity interest or control are accounted for using theequity method of accounting in accordance with ASC topic 323 (“ASC 323”), Investment– Equity Method and Joint Ventures. Under the equity method, the Group initially recordsits investments at cost and the difference between the cost of the equity investee and thefair value of the underlying equity in the net assets of the equity investee is recognizedas equity method goodwill, which is included in the equity method investment on theunaudited interim condensed consolidated balance sheets. The Group subsequentlyadjusts the carrying amount of the investments to recognize the Group’s proportionateshare of each equity investee’s net income or loss into earnings after the date ofinvestment. The Group evaluates the equity method investments for impairment underASC 323. An impairment loss on the equity method investments is recognized in earningswhen the decline in value is determined to be other-than-temporary.

Long-term investments (continued)

In January 2020, the FASB issued ASU No. 2020-01, Investments – Equity Securities(Topic 321), Investments – Equity Method and Joint Ventures (Topic 323), andDerivatives and Hedging (Topic 815) – Clarifying the Interactions between Topic 321,Topic 323, and Topic 815 (a consensus of the Emerging Issues Task Force). Theamendments in this update clarify the interaction of the accounting for equity securitiesunder Topic 321 and investments accounted for under the equity method of accounting inTopic 323 and the accounting for certain forward contracts and purchased optionsaccounted for under Topic 815. For public business entities, the amendments in thisUpdate are effective for fiscal years beginning after December 15, 2020, and interimperiods within those fiscal years. For all other entities, the amendments are effective forfiscal years beginning after December 15, 2021, and interim periods within those fiscalyears. Early adoption is permitted. The Group adopted the ASU on January 1, 2021, whichdid not have a material impact on the unaudited interim condensed consolidated financialstatements.

Business combination

Business combinations are recorded using the purchase method of accounting, and thecost of an acquisition is measured as the aggregate of the fair values at the date ofexchange of the assets given, liabilities incurred, and equity instruments issued as well asthe contingent considerations and all contractual contingencies as of the acquisition date.The costs directly attributable to the acquisition are expensed as incurred. Identifiableassets, liabilities and contingent liabilities acquired or assumed are measured separatelyat their fair value as of the acquisition date, irrespective of the extent of anynon-controlling interests. The excess of the (i) the total of consideration paid, fair valueof the non-controlling interests and acquisition date fair value of any previously heldequity interest in the subsidiary acquired over (ii) the fair value of the identifiable netassets of the subsidiary acquired is recorded as goodwill. If the consideration ofacquisition is less than the fair value of the net assets of the subsidiary acquired, thedifference is recognized directly in the unaudited interim condensed consolidatedstatements of comprehensive income.

Leases

In February 2016, the FASB issued a new standard on leases, ASU 2016-02, “Leases(Topic 842)”, which requires a lessee to recognize assets and liabilities arising fromoperating leases. A lessee should recognize a liability to make lease payments (the LeaseLiability) and a right-of-use asset (the Operating Lease Assets) representing its right touse the underlying asset for the lease term. For leases with a term of twelve months orless, a lessee is permitted to make an accounting policy choice not to recognize leaseassets and lease liabilities. In July 2018, the FASB issued an amendment, ASU 2018-11,which provides another transition method in addition to the existing transition methods byallowing entities to initially apply the new leases standard at the effective date andrecognize a cumulative-effect adjustment to the opening balance of retained earnings inthe period of adoption and to not retrospectively adjust prior periods financial statements.

2. Significant Accounting Policies (continued)

Leases (continued)

On January 1, 2019, the Group adopted the new lease standard using the transition methodby applying the standard to all leases existing at the date of initial application. The Groupchose to not recognize lease assets and lease liabilities for leases with a term of twelvemonths or less, to not separate non-lease components from lease components, and to notreassess lease classification, treatment of initial direct costs or whether an existing orexpired contract contains a lease according to the practical expedients permitted under thetransition method.

The Group did not retrospectively adjust the prior comparative periods. Under the newlease standard, the Group determines if an arrangement is or contains a lease at inception.Right-of-use assets and liabilities are recognized at lease commencement date based onthe present value of remaining lease payments over the lease terms. The Group considersonly payments that are fixed and determinable at the time of lease commencement.

Long-lived assets

Property and equipment

Property and equipment are stated at cost less accumulated depreciation, amortization andimpairment, if any. Depreciation is computed using the straight-line method over theestimated useful lives of the assets, generally from three to four years for computers andequipment and five years for furniture and fixtures. Leasehold improvements areamortized over the shorter of the estimated useful lives of the assets or the remaininglease term. Depreciation expenses were $18.9 million and $24.3 million for the ninemonths ended September 30, 2020 and 2021, respectively.

Goodwill

Goodwill represents the excess of the purchase price over the fair value of the identifiableassets and liabilities acquired as a result of the Group’s acquisitions of interests in itssubsidiaries, consolidated VIEs and VIEs’ subsidiaries. The Group assesses goodwill forimpairment in accordance with ASC Subtopic 350-20 (“ASC 350-20”), Intangibles –Goodwill and Other: Goodwill, which requires that goodwill be tested for impairment atthe reporting unit level at least annually and more frequently upon the occurrence ofcertain events, as defined by ASC 350-20. The guidance provides option that the Groupmay first assess qualitative factors to determine whether it is necessary to perform thequantitative goodwill impairment test, by taking into consideration of macroeconomics,overall financial performance, industry and market conditions and the share price of theGroup. If determined to be necessary, the quantitative impairment test shall be used toidentify goodwill impairment and measure the amount of a goodwill impairment loss tobe recognized (if any). Application of a goodwill impairment test requires significantmanagement judgment, including the identification of reporting units, assigning assetsand liabilities to reporting units, assigning goodwill to reporting units, and determining

the fair value of each reporting unit. Judgment in estimating the fair value of reportingunits includes estimating future cash flows, determining appropriate discount rates andmaking other assumptions. Changes in these estimates and assumptions could materiallyaffect the determination of fair value for each reporting unit. For nine months endedSeptember 30, 2020 and 2021, no impairment indicator was noted by performingqualitative analysis, therefore, no provision was recorded.

Intangible assets other than goodwill

Intangible assets arising from acquisitions are recognized at fair value upon acquisitionand amortized on a straight-line basis over their estimated useful lives, generally fromthree to ten years. Long-lived assets and certain identifiable intangible assets other thangoodwill to be held and used are reviewed for impairment whenever events or changes incircumstances indicate that the carrying amount of such assets may not be recoverable.Determination of recoverability is based on an estimate of undiscounted future cash flowsresulting from the use of the asset and its eventual disposition. Measurement of anyimpairment loss for long-lived assets and certain identifiable intangible assets thatmanagement expects to hold or use is based on the amount by which the carrying valueexceeds the fair value of the asset. Judgment is used in estimating future cash flows,determining appropriate discount rates and making other assumptions. Changes in theseestimates and assumptions could materially affect the determination of the asset’s fairvalue.

Convertible debt and unsecured senior notes

The Group determines the appropriate accounting treatment of its convertible debt inaccordance with the terms in relation to the conversion feature. After considering theimpact of such features, the Group may account for such instrument as a liability in itsentirety, or separate the instrument into debt and equity components following therespective guidance described under ASC 815 Derivatives and Hedging and ASC 470Debt.

The debt discount, if any, together with related issuance cost are subsequently amortizedas interest expense over the contractual life. The Group presented the issuance costs ofdebt as a direct deduction from the related debt during the periods presented.

Convertible debt and unsecured senior notes (continued)

The unsecured senior notes are recognized initially at fair value, net of debt discounts orpremiums, if any, issuance costs and other incidental fees, all of which are recorded as adirect deduction of the proceeds received from issuing the unsecured senior notes and therelated accretion is recorded as interest expense in the unaudited interim condensedconsolidated statement of comprehensive income over the estimated term using theeffective interest method.

Deferred revenues

Deferred revenues consist of contractual billings in excess of recognized revenue andpayments received in advance of revenue recognition, which are mainly from thecustomer advance of the advertising and marketing services and the sales of the fee-basedservices, such as VIP membership, live streaming, and virtual currency or in-game virtualitems sold for game related services.

Non-controlling interests

For the Company’s majority-owned subsidiaries and VIE, non-controlling interests arerecognized to reflect the portion of their equity that is not attributable, directly orindirectly, to the Company as the controlling shareholder. To reflect the economic interestheld by non-controlling shareholders, net income/loss attributable to the non-controllingordinary shareholders is recorded as non-controlling interests in the Company’s unauditedinterim condensed consolidated statements of comprehensive income. Non-controllinginterests are classified as a separate line item in the equity section of the Company’sunaudited interim condensed consolidated balance sheets and have been separatelydisclosed in the Company’s unaudited interim condensed consolidated financialstatements to distinguish the interests from that of the Company.

Foreign currency

The Company’s reporting currency and functional currency is the U.S. dollar. TheGroup’s operations in China and in international regions use their respective currenciesas their functional currencies. The financial statements of these subsidiaries are translatedinto U.S. dollars using period-end rates of exchange for assets and liabilities and averagerates of exchange in the period for revenues, costs and expenses. Translation gains andlosses are recorded in accumulated other comprehensive income (loss) as a component ofshareholders’ equity. Translation gains or losses are not released to net income unless theassociated net investment has been sold, liquidated, or substantially liquidated.

Foreign currency (continued)

Foreign currency transactions denominated in currencies other than the functionalcurrency are translated into the functional currency using the exchange rate prevailing onthe transactions dates. Monetary assets and liabilities denominated in foreign currenciesare translated into the functional currency using the applicable exchange rates at thebalance sheet dates. Net gains and losses resulting from foreign exchange transactions areincluded in other income, net.

Foreign currency translation adjustments included in the Group’s unaudited interimcondensed consolidated statements of comprehensive income for the nine months endedSeptember 30, 2020 and 2021 were gains of $57.7 million and $34.9 million respectively.Net foreign currency transaction gains or losses arise from transacting in a currency otherthan the functional currency of the entity and the amounts recorded were immaterial foreach of the periods presented.

Net income per share

Basic net income per share is computed using the weighted average number of ordinaryshares outstanding during the period. Options and RSUs are not considered outstandingin the computation of basic earnings per share. Diluted net income per share is computedusing the weighted average number of ordinary shares and potential ordinary sharesoutstanding during the period, which include options to purchase ordinary shares,restricted share units and conversion of the convertible debt. The computation of dilutednet income per share does not assume conversion, exercise, or contingent issuance ofsecurities that would have an anti-dilutive effect (i.e. an increase in earnings per shareamounts or a decrease in loss per share amounts) on net income per share. The Group usesthe two-class method to calculate net income per share though both classes share the samerights in dividends. Therefore, basic and diluted earnings per share are the same for bothclasses of ordinary shares.

Segment reporting

In accordance with ASC 280, Segment Reporting, the Group’s chief operating decisionmaker (“CODM”), the Chief Executive Officer, reviews the consolidated results whenmaking decisions about allocating resources and assessing performance of the Group asa whole. The Group currently operates and manages its business in two principal businesssegments globally – advertising and marketing services and value-added services.Information regarding the business segments provided to the Group’s CODM is at therevenue level and the Group currently does not allocate operating costs or assets to itssegments, as its CODM does not use such information to allocate resources or evaluatethe performance of the operating segments. As the Group’s long-lived assets aresubstantially all located in the PRC and substantially the Group’s revenues are derivedfrom within the PRC, no geographical information is presented.

Concentration of risks

Concentration of credit risk. Financial instruments that potentially subject the Group toa concentration of credit risk consist primarily of cash and cash equivalents, short-terminvestments and accounts receivable. In addition, with the majority of its operations inChina, the Group is subject to RMB currency risk and offshore remittance risk, both ofwhich have been difficult to hedge and the Group has not done so. The Group limits itsexposure to credit loss by depositing its cash and cash equivalents with financialinstitutions in the US, PRC and Hong Kong, which are among the largest and mostrespected financial institutions with high ratings from internationally-recognized ratingagencies, that management believes are of high credit quality. The Group periodicallyreviews these institutions’ reputations, track records and reported reserves.

As of December 31, 2020 and September 30, 2021, the Group had $3.0 billion and $2.2billion, respectively, in cash and bank time deposits (with terms generally up to twelvemonths) with large domestic banks in China. China promulgated a Bankruptcy Law thatcame into effect on June 1, 2007, which contains a separate article expressly stating thatthe State Council may promulgate implementation measures for the bankruptcy ofChinese banks based on the Bankruptcy Law. Under the Bankruptcy Law, a Chinese bankmay go bankrupt. In addition, since China’s concession to WTO, foreign banks have beengradually permitted to operate in China and have become significant competitors toChinese banks in many aspects, especially since the opening of RMB business to foreignbanks in late 2006. Therefore, the risk of bankruptcy on Chinese banks in which theGroup holds cash and bank deposits has increased. In the event that a Chinese bank thatholds the Group’s deposits goes bankrupt, the Group is unlikely to claim its deposits backin full, since it is unlikely to be classified as a secured creditor to the bank under the PRClaws.

Alibaba, as an advertiser, accounted for 8% and 6% of the Group’s total revenues for thenine months ended September 30, 2020 and 2021, respectively. No customer noradvertising agency accounted for 10% or more of the Group’s revenues. The Group’s top10 advertising agencies contributed to 32% and 40% of the Group’s revenues for the ninemonths ended September 30, 2020 and 2021, respectively.

As of December 31, 2020 and September 30, 2021, substantially all accounts receivablewere derived from the Group’s China operations. Excluding accounts receivable due fromAlibaba and other related parties, accounts receivable primarily consist of amounts duefrom advertising agencies and direct customers. Alibaba accounted for 28% and 14% ofthe Group’s net accounts receivable as of December 31, 2020 and September 30, 2021,respectively.

Concentration of risks (continued)

Concentration of foreign currency risks. The majority of the Group’s operations were inRMB. As of December 31, 2020 and September 30, 2021, the Group’s cash, cashequivalents and short-term investments balance denominated in RMB was $1,651.3million and $1,228.0 million, accounting for 47% and 45% of the Group’s total cash, cashequivalents and short-term investments balance at the respective dates. As of December31, 2020 and September 30, 2021, the Group’s aggregate net accounts receivable balance(including accounts receivable due from third parties, Alibaba and other related parties)denominated in RMB was $492.0 million and $683.7 million, respectively, accounting foralmost all of its net accounts receivable balance. As of December 31, 2020 and September30, 2021, the Group’s current liabilities balance denominated in RMB was $947.6 millionand $1,139.0 million, accounting for 99% and 98% of its total current liabilities balance.Accordingly, the Group may experience economic losses and negative impacts onearnings and equity as a result of exchange rate fluctuations of the RMB against the U.S.dollars. Moreover, the Chinese government imposes controls on the convertibility of theRMB into foreign currencies and, in certain cases, the remittance of currency out of thePRC. The Group may experience difficulties in completing the administrative proceduresnecessary to remit its RMB out of the PRC and convert it into foreign currency.

Recent accounting pronouncements

In May 2021, the FASB issued ASU No. 2021-04, Earnings Per Share (Topic 260), Debt– Modifications and Extinguishments (Subtopic 470-50), Compensation – StockCompensation (Topic 718), and Derivatives and Hedging – Contracts in Entity’s OwnEquity (Subtopic 815-40) to clarify and reduce diversity in an issuer’s accounting formodifications or exchanges of freestanding equity-classified written call options (forexample, warrants) that remain equity classified after modification or exchange. Theamendments in this update are effective for all entities for fiscal years beginning afterDecember 15, 2021, including interim periods within those fiscal years. An entity shouldapply the amendments prospectively to modifications or exchanges occurring on or afterthe effective date of the amendments. The ASU is currently not expected to have amaterial impact on the unaudited interim condensed consolidated financial statements.

Based on ASU 2016-01, entities that elect the measurement alternative willreport changes in the carrying value of the equity investments in current earnings. Ifmeasurement alternative is used, changes in the carrying value of the equity investmentwill be recognized whenever there are observable price changes in orderly transactionsfor the identical or similar investment of the same issuer, and impairment charges will berecorded when any impairment indicators are noted and the fair value is lower than thecarrying value. The Group classifies the valuation techniques on investments that usesimilar identifiable transaction prices as Level 2 of fair value measurements.

5. Leases

The Group has operating leases primarily for office spaces in China. The determinationof whether an arrangement is or contains a lease is made at inception by evaluatingwhether the arrangement conveys the right to use an identified asset and whether theGroup obtains substantially all of the economic benefits from and has the ability to directthe use of the asset. Operating lease assets and liabilities are included in operating leaseright-of-use assets, operating lease liabilities, short-term, and operating lease liabilities,long-term on the Group’s unaudited interim condensed consolidated balance sheets. TheGroup has chosen to not recognize lease assets and lease liabilities for leases with a termof twelve months or less on the unaudited interim condensed consolidated balance sheets.

5. Leases (continued)

Operating lease right-of-use assets and operating lease liabilities are recognized based onthe present value of lease payments over the lease terms at the lease commencementdates. The Group uses its incremental borrowing rate in determining the present value oflease payments. The incremental borrowing rate is a hypothetical rate based on theGroup’s understanding of what interest the Group would pay in order to obtain aborrowing with an amount equivalent to the lease payments in a similar economicenvironment over the lease term on a collateralized basis from banks in China.

Certain lease agreements contain an option for the Group to renew a lease for a termagreed by the Group and the lessor or an option to terminate a lease earlier than thematurity dates. The Group considers these options, which may be elected at the Group’ssole discretion, in determining the lease term on a lease-by-lease basis. The Group’s leaseagreements generally do not contain any residual value guarantees or material restrictivecovenants. Certain of the Group’s leases contain free or escalating rent payment terms.The Group’s lease agreements generally contain lease and non-lease components.Non-lease components primarily include payments for maintenance and utilities. TheGroup has chosen to combine payments for non-lease components with lease paymentsand accounted them together as a single lease component. Payments under the leasearrangements are primarily fixed. However, for arrangements accounted for as a singlelease component, there may be variability in future lease payments as the amount of thenon-lease components is typically revised from one period to the next. Additionally,certain lease agreements with SINA contain variable payments, which are determinedbased on actual SINA headquarters spaces occupied by the Group and are expensed asincurred and not included in the operating lease assets and liabilities.

as “software enterprise”, “key software enterprise” (“KSE”) and/or “high and newtechnology enterprise” (“HNTE”). Weibo Technology, the Group’s WFOE, was qualifiedas a “software enterprise” in 2020, it will not enjoy a reduced tax rate for its “softwareenterprise” status as it has been five years since its first profitable year of 2015 and it hasalready benefited from the preferential tax treatment of “software enterprise” status from2015 to 2019. Weibo Technology was also granted the HNTE status for the fiscal yearsfrom 2017 to 2022, which entitled the qualified entity a preferential tax rate of 15% in2020 and 2021. Its qualification as a HNTE is subject to annual evaluation and athree-year review by the relevant authorities in China. In addition, certain of the Group’sother PRC entities are also qualified as a “software enterprise”, and/or HNTE, andcurrently enjoy the respective preferential tax treatments.

The EIT Law also provides that an enterprise established under the laws of a foreigncountry or region but whose “de facto management body” is located in the PRC be treatedas a resident enterprise for PRC tax purposes and consequently be subject to the PRCincome tax at the rate of 25% for its global income. The Implementing Rules of the EITLaw merely define the location of the “de facto management body” as “the place wherethe exercising, in substance, of the overall management and control of the production andbusiness operation, personnel, accounting, properties, etc., of a non-PRC company islocated.” Based on a review of surrounding facts and circumstances, the Group does notbelieve that it is likely that its operations outside of the PRC be considered a residententerprise for PRC tax purposes. However, due to limited guidance and implementationhistory of the EIT Law, should Weibo be treated as a resident enterprise for PRC taxpurposes, the Company will be subject to PRC tax on worldwide income at a uniform taxrate of 25% retroactive to January 1, 2008.

The EIT Law also imposes a withholding income tax rate of 10% on dividends distributedby a WFOE to its immediate holding company outside of China, if such immediateholding company is considered as a non-resident enterprise without any establishment orplace within China or if the received dividends have no connection with the establishmentor place of such immediate holding company within China, unless such immediateholding company’s jurisdiction of incorporation has a tax treaty with China that providesfor a different withholding arrangement. The Cayman Islands, where the Companyincorporated, does not have such tax treaty with China. According to the arrangementbetween Mainland China and Hong Kong Special Administrative Region on theAvoidance of Double Taxation and Prevention of Fiscal Evasion in August 2006,dividends paid by a WFOE in China to its immediate holding company in Hong Kong willbe subject to withholding tax at a rate of no more than 5% (if the foreign investor ownsdirectly at least 25% of the shares of the WFOE). The State Administration of Taxationfurther promulgated Circular 601 on October 27, 2009, which provides that tax treatybenefits will be denied to “conduit” or shell companies without business substance andthat a beneficial ownership analysis will be used based on a “substance-over-form”principle to determine whether or not to grant the tax treaty benefits.

China (continued)

The operations of the Group’s WFOE in China are invested and held by Weibo HK. If theCompany is regarded as a non-resident enterprise and Weibo HK is regarded as a residententerprise, then Weibo HK may be required to pay a 10% withholding tax on anydividends payable to the Company. If Weibo HK is regarded as a non-resident enterprise,then Weibo Technology may be required to pay a 5% withholding tax for any dividendspayable to Weibo HK. However, it is still unclear at this stage whether Circular 601applies to dividends from Weibo Technology paid to Weibo HK. If Weibo HK were notconsidered as “beneficial owners” of any dividends from Weibo Technology, thedividends payable to Weibo HK would be subject to a withholding tax of 10%. Thecurrent policy approved by the Company’s board of directors allows the Group todistribute PRC earnings offshore only if the Group does not have to pay a dividend tax.As of September 30, 2021, the Group did not record any withholding tax for its PRCsubsidiaries.

According to the relevant laws and regulations in the PRC, enterprises engaging inresearch and development activities were entitled to claim 150% of their research anddevelopment expenses incurred as tax deductible expenses when determining theirassessable profits for that year (the “R&D Deduction”). The State TaxationAdministration of the PRC announced in September 2018 that enterprises engaging inresearch and development activities would be entitled to claim 175% of their research anddevelopment expenses as R&D Deduction from January 1, 2018 to December 31, 2020.

Deferred tax assets and liabilities (continued)

Valuation allowance is provided against deferred tax assets when the Group determinesthat it is more likely than not that the deferred tax assets will not be utilized in the future.In making such determination, the Group considered factors including (i) future reversalsof existing taxable temporary differences; (ii) future taxable income exclusive ofreversing temporary differences and carry forwards; and (iii) tax planning strategies. Thevaluation allowance on deferred tax assets as of December 31, 2020 and September 30,2021 was $89.7 million and $91.0 million, respectively. The valuation allowanceprimarily consists of bad debt expenses and investment impairment charges/fair valuechange of investments. Historically, deferred tax assets were valued using the statutoryrate of 25% for China operations. Net operating loss carry forwards for China operationsas of December 31, 2020 will expire, if unused, in the years ending December 31, 2021through December 31, 2025.

Uncertain tax position

Except for the lag recognition of preferential tax treatment of KSE status, research anddevelopment super deduction and stock based related deduction, the Group did not recordany liability or decrease in deferred tax asset related to uncertain tax positions as ofDecember 31, 2020 and September 30, 2021, and thus, no interest and penalties relatedto uncertain tax positions were recorded.

For the nine months ended September 30, 2021, based on interactions with the taxauthorities, the Group received additional guidance regarding certain areas withheightened requirements, and updated its estimate of related tax benefit amount that isexpected to be sustained upon settlement with tax authorities. Additional $27.9 milliontax liability related to uncertain tax positions was recognized for the nine months endedSeptember 30, 2021, which is based on the updated estimate of the largest amount of taxbenefit that is greater than 50% likely to be realized upon settlement with the taxauthorities. It is possible that the estimate and ultimate resolution of these uncertain taxpositions may further change based on further interactions with the tax authorities.

In general, the PRC tax authorities have up to five years to review a company’s tax filings.Accordingly, tax filings of the Company’s PRC subsidiaries and VIEs for tax years 2016through 2020 remain subject to the review by the relevant PRC tax authorities.

17. Commitments and Contingencies (continued)

There are uncertainties regarding the legal basis of the Group’s ability to operate anInternet business in China. Although China has implemented a wide range of market-oriented economic reforms, the telecommunication, information and media industriesremain highly regulated. Not only are such restrictions currently in place, the existingregulations are unclear as to which specific segments of these industries companies withforeign investors, including the Company, may operate. Therefore, the Group may berequired to limit the scope of its operations in China, and this could have a materialadverse effect on its financial position, results of operations and cash flows.

There are no claims, lawsuits, investigations or proceedings, including unasserted claimsthat are probable to be assessed, that have in the recent past had, or to the Group’sknowledge, are reasonably possible to have, a material impact on the Group’s financialstatements.

18. Redeemable Non-controlling Interests

In the fourth quarter of 2020, the Group entered into a series of share purchaseagreements with then existing shareholders of Shanghai Jiamian Information TechnologyCo., Ltd. (“JM Tech”) to acquire the majority of the company’s equity interest. The Groupagreed to redeem the non-controlling interests held by founders and CEO of the companyunder certain circumstances during the following years subsequent to the acquisition. TheGroup determined that the non-controlling interest with redemption rights should beclassified as redeemable non-controlling interest since they are contingently redeemableupon the occurrence of certain conditional events, which are not solely within the controlof the Group.

The redeemable non-controlling interests is recognized at fair value on the acquisitiondate. The Group records accretion on the redeemable non-controlling interest to theredemption value over the period from the date of the acquisition to the date of earliestredemption. The accretion using the effective interest method, is recorded as deemeddividends to preferred shareholders, which reduce retained earnings and equity classifiednon-controlling interests, and earnings available to common shareholders in calculatingbasic and diluted earnings per share.

The process of adjusting redeemable non-controlling interests to its redemption value (the“Mezzanine Adjustment”) should be performed after attribution of the subsidiary’s netincome or loss pursuant to ASC 810, Consolidation. The carrying amount of redeemablenon-controlling interests will equal the higher of the amount resulting from application ofASC 810 or the amount resulting from the Mezzanine Adjustment. As the expectedredemption value is less than the carrying value of redeemable non-controlling interests,there is nil mezzanine adjustment recognized for the nine months ended September 30,2021.

Pursuant to the agreements between the Group and the founders who are also employeesof JM Tech, the founders are required to be in employment during the following two yearstill December 31, 2022 to be entitled to their proportionate share in JM Tech’s existingand future retained earnings during the period. Such entitlement will automatically beforfeited upon the termination of their employment during the period.

The Board of Directors shall give not less than 14 days’notice of a shareholders’ meeting to all shareholders other than such as, under the provisionshereof or the terms of issue of the shares they hold, are not entitled to receive such notice fromthe Company.

Cayman Islands law provides shareholders with only limited rights to requisition a generalmeeting, and does not provide shareholders with any right to put any proposal before a generalmeeting. However, these rights may be provided in a company’s articles of association. TheMemorandum and Articles of Association allow any two or more shareholders holding sharesrepresenting in aggregate not less than one-third of the total voting rights in the paid up capitalof the Company to requisition an extraordinary general meeting, in which case the directors areobliged to call such meeting; however, the Memorandum and Articles of Association do notprovide the shareholders with any right to put any proposals before annual general meetings orextraordinary general meetings.

SUMMARY OF CAYMAN ISLANDS COMPANY LAW AND TAXATION

1 Introduction

The Companies Act is derived, to a large extent, from the older Companies Acts of England,although there are significant differences between the Companies Act and the currentCompanies Act of England. Set out below is a summary of certain provisions of the CompaniesAct, although this does not purport to contain all applicable qualifications and exceptions orto be a complete review of all matters of corporate law and taxation which may differ fromequivalent provisions in jurisdictions with which interested parties may be more familiar.

2 Incorporation

The Company was incorporated in the Cayman Islands as an exempted company with limitedliability on April 8, 2015 under the Companies Act. As such, its operations must be conductedmainly outside the Cayman Islands. The Company is required to file an annual return each yearwith the Registrar of Companies of the Cayman Islands and pay a fee which is based on thesize of its authorised share capital.

3 Share Capital

The Companies Act permits a company to issue ordinary shares, preference shares, redeemableshares or any combination thereof.

APPENDIX III SUMMARY OF OUR CONSTITUTIONAND CAYMAN COMPANY LAW

– III-7 –

The Companies Act provides that where a company issues shares at a premium, whether forcash or otherwise, a sum equal to the aggregate amount of the value of the premia on thoseshares shall be transferred to an account called the “share premium account”. At the option ofa company, these provisions may not apply to premia on shares of that company allottedpursuant to any arrangement in consideration of the acquisition or cancellation of shares in anyother company and issued at a premium. The Companies Act provides that the share premiumaccount may be applied by a company, subject to the provisions, if any, of its memorandum andarticles of association, in such manner as the company may from time to time determineincluding, but without limitation:

(a) paying distributions or dividends to members;

(b) paying up unissued shares of the company to be issued to members as fully paid bonusshares;

(c) in the redemption and repurchase of shares (subject to the provisions of section 37 of theCompanies Act);

(d) writing-off the preliminary expenses of the company;

(e) writing-off the expenses of, or the commission paid or discount allowed on, any issue ofshares or debentures of the company; and

(f) providing for the premium payable on redemption or purchase of any shares or debenturesof the company.

No distribution or dividend may be paid to members out of the share premium account unlessimmediately following the date on which the distribution or dividend is proposed to be paid thecompany will be able to pay its debts as they fall due in the ordinary course of business.

The Companies Act provides that, subject to confirmation by the Grand Court of the CaymanIslands, a company limited by shares or a company limited by guarantee and having a sharecapital may, if so authorised by its articles of association, by special resolution reduce its sharecapital in any way.

Subject to the detailed provisions of the Companies Act, a company limited by shares or acompany limited by guarantee and having a share capital may, if so authorised by its articlesof association, issue shares which are to be redeemed or are liable to be redeemed at the optionof the company or a shareholder. In addition, such a company may, if authorised to do so byits articles of association, purchase its own shares, including any redeemable shares. Themanner of such a purchase must be authorised either by the articles of association or by anordinary resolution of the company. The articles of association may provide that the manner ofpurchase may be determined by the directors of the company. At no time may a companyredeem or purchase its shares unless they are fully paid. A company may not redeem orpurchase any of its shares if, as a result of the redemption or purchase, there would no longerbe any member of the company holding shares. A payment out of capital by a company for theredemption or purchase of its own shares is not lawful unless immediately following the dateon which the payment is proposed to be made, the company shall be able to pay its debts asthey fall due in the ordinary course of business.

APPENDIX III SUMMARY OF OUR CONSTITUTIONAND CAYMAN COMPANY LAW

– III-8 –

There is no statutory restriction in the Cayman Islands on the provision of financial assistanceby a company for the purchase of, or subscription for, its own or its holding company’s shares.Accordingly, a company may provide financial assistance if the directors of the companyconsider, in discharging their duties of care and to act in good faith, for a proper purpose andin the interests of the company, that such assistance can properly be given. Such assistanceshould be on an arm’s-length basis.

4 Dividends and Distributions

With the exception of section 34 of the Companies Act, there are no statutory provisionsrelating to the payment of dividends. Based upon English case law which is likely to bepersuasive in the Cayman Islands in this area, dividends may be paid only out of profits. Inaddition, section 34 of the Companies Act permits, subject to a solvency test and theprovisions, if any, of the company’s memorandum and articles of association, the payment ofdividends and distributions out of the share premium account (see paragraph Summary of theConstitution of Our Company — 2 Articles of Association — 2.2 Dividends above for details).

5 Shareholders’ Suits

The Cayman Islands courts can be expected to follow English case law precedents. The rule inFoss v. Harbottle (and the exceptions thereto which permit a minority shareholder tocommence a class action against or derivative actions in the name of the company to challenge(a) an act which is ultra vires the company or illegal, (b) an act which constitutes a fraudagainst the minority where the wrongdoers are themselves in control of the company, and (c) anaction which requires a resolution with a qualified (or special) majority which has not beenobtained) has been applied and followed by the courts in the Cayman Islands.

6 Protection of Minorities

In the case of a company (not being a bank) having a share capital divided into shares, theGrand Court of the Cayman Islands may, on the application of members holding not less thanone-fifth of the shares of the company in issue, appoint an inspector to examine into the affairsof the company and to report thereon in such manner as the Grand Court shall direct.

Any shareholder of a company may petition the Grand Court of the Cayman Islands which maymake a winding up order if the court is of the opinion that it is just and equitable that thecompany should be wound up.

Claims against a company by its shareholders must, as a general rule, be based on the generallaws of contract or tort applicable in the Cayman Islands or their individual rights asshareholders as established by the company’s memorandum and articles of association.

The English common law rule that the majority will not be permitted to commit a fraud on theminority has been applied and followed by the courts of the Cayman Islands.

7 Disposal of Assets

The Companies Act contains no specific restrictions on the powers of directors to dispose ofassets of a company. As a matter of general law, in the exercise of those powers, the directorsmust discharge their duties of care and to act in good faith, for a proper purpose and in theinterests of the company.

APPENDIX III SUMMARY OF OUR CONSTITUTIONAND CAYMAN COMPANY LAW

– III-9 –

8 Accounting and Auditing Requirements

The Companies Act requires that a company shall cause to be kept proper books of accountwith respect to:

(a) all sums of money received and expended by the company and the matters in respect ofwhich the receipt and expenditure takes place;

(b) all sales and purchases of goods by the company; and

(c) the assets and liabilities of the company.

Proper books of account shall not be deemed to be kept if there are not kept such books as arenecessary to give a true and fair view of the state of the company’s affairs and to explain itstransactions.

9 Register of Members

An exempted company may, subject to the provisions of its articles of association, maintain itsprincipal register of members and any branch registers at such locations, whether within orwithout the Cayman Islands, as its directors may from time to time think fit. There is norequirement under the Companies Act for an exempted company to make any returns ofmembers to the Registrar of Companies of the Cayman Islands. The names and addresses of themembers are, accordingly, not a matter of public record and are not available for publicinspection.

10 Inspection of Books and Records

Members of a company will have no general right under the Companies Act to inspect or obtaincopies of the register of members or corporate records of the company. They will, however,have such rights as may be set out in the company’s articles of association.

11 Special Resolutions

The Companies Act provides that a resolution is a special resolution when it has been passedby a majority of at least two-thirds of such members as, being entitled to do so, vote in personor, where proxies are allowed, by proxy at a general meeting of which notice specifying theintention to propose the resolution as a special resolution has been duly given, except that acompany may in its articles of association specify that the required majority shall be a numbergreater than two-thirds, and may additionally so provide that such majority (being not less thantwo-thirds) may differ as between matters required to be approved by a special resolution.Written resolutions signed by all the members entitled to vote for the time being of thecompany may take effect as special resolutions if this is authorised by the articles ofassociation of the company.

12 Subsidiary Owning Class A ordinary shares in Parent

The Companies Act does not prohibit a Cayman Islands company acquiring and holding sharesin its parent company provided its objects so permit. The directors of any subsidiary makingsuch acquisition must discharge their duties of care and to act in good faith, for a properpurpose and in the interests of the subsidiary.

APPENDIX III SUMMARY OF OUR CONSTITUTIONAND CAYMAN COMPANY LAW

– III-10 –

13 Mergers and Consolidations

The Companies Act permits mergers and consolidations between Cayman Islands companiesand between Cayman Islands companies and non-Cayman Islands companies. For thesepurposes, (a) “merger” means the merging of two or more constituent companies and thevesting of their undertaking, property and liabilities in one of such companies as the survivingcompany, and (b) “consolidation” means the combination of two or more constituentcompanies into a consolidated company and the vesting of the undertaking, property andliabilities of such companies to the consolidated company. In order to effect such a merger orconsolidation, the directors of each constituent company must approve a written plan of mergeror consolidation, which must then be authorised by (a) a special resolution of each constituentcompany and (b) such other authorisation, if any, as may be specified in such constituentcompany’s articles of association. The written plan of merger or consolidation must be filedwith the Registrar of Companies of the Cayman Islands together with a declaration as to thesolvency of the consolidated or surviving company, a list of the assets and liabilities of eachconstituent company and an undertaking that a copy of the certificate of merger orconsolidation will be given to the members and creditors of each constituent company and thatnotification of the merger or consolidation will be published in the Cayman Islands Gazette.Dissenting shareholders have the right to be paid the fair value of their shares (which, if notagreed between the parties, will be determined by the Cayman Islands court) if they follow therequired procedures, subject to certain exceptions. Court approval is not required for a mergeror consolidation which is effected in compliance with these statutory procedures.

14 Reconstructions

There are statutory provisions which facilitate reconstructions and amalgamations approved bya majority in number representing 75% in value of shareholders or creditors, depending on thecircumstances, as are present at a meeting called for such purpose and thereafter sanctioned bythe Grand Court of the Cayman Islands. Whilst a dissenting shareholder would have the rightto express to the Grand Court his view that the transaction for which approval is sought wouldnot provide the shareholders with a fair value for their shares, the Grand Court is unlikely todisapprove the transaction on that ground alone in the absence of evidence of fraud or bad faithon behalf of management and if the transaction were approved and consummated the dissentingshareholder would have no rights comparable to the appraisal rights (i.e. the right to receivepayment in cash for the judicially determined value of his shares) ordinarily available, forexample, to dissenting shareholders of United States corporations.

15 Take-overs

Where an offer is made by a company for the shares of another company and, within fourmonths of the offer, the holders of not less than 90% of the shares which are the subject of theoffer accept, the offeror may at any time within two months after the expiration of the said fourmonths, by notice require the dissenting shareholders to transfer their shares on the terms ofthe offer. A dissenting shareholder may apply to the Grand Court of the Cayman Islands withinone month of the notice objecting to the transfer. The burden is on the dissenting shareholderto show that the Grand Court should exercise its discretion, which it will be unlikely to dounless there is evidence of fraud or bad faith or collusion as between the offeror and the holdersof the shares who have accepted the offer as a means of unfairly forcing out minorityshareholders.

APPENDIX III SUMMARY OF OUR CONSTITUTIONAND CAYMAN COMPANY LAW

– III-11 –

16 Indemnification

Cayman Islands law does not limit the extent to which a company’s articles of association mayprovide for indemnification of officers and directors, except to the extent any such provisionmay be held by the Cayman Islands courts to be contrary to public policy (e.g. for purportingto provide indemnification against the consequences of committing a crime).

17 Liquidation

A company may be placed in liquidation compulsorily by an order of the court, or voluntarily(a) by a special resolution of its members if the company is solvent, or (b) by an ordinaryresolution of its members if the company is insolvent. The liquidator’s duties are to collect theassets of the company (including the amount (if any) due from the contributories(shareholders)), settle the list of creditors and discharge the company’s liability to them,rateably if insufficient assets exist to discharge the liabilities in full, and to settle the list ofcontributories and divide the surplus assets (if any) amongst them in accordance with the rightsattaching to the shares.

18 Stamp Duty on Transfers

No stamp duty is payable in the Cayman Islands on transfers of shares of Cayman Islandscompanies except those which hold interests in land in the Cayman Islands.

19 Taxation

Pursuant to section 6 of the Tax Concessions Act (As Revised) of the Cayman Islands, theCompany may obtain an undertaking from the Financial Secretary of the Cayman Islands:

(a) that no law which is enacted in the Cayman Islands imposing any tax to be levied onprofits, income, gains or appreciations shall apply to the Company or its operations; and

(b) in addition, that no tax to be levied on profits, income, gains or appreciations or whichis in the nature of estate duty or inheritance tax shall be payable:

(i) on or in respect of the shares, debentures or other obligations of the Company; or

(ii) by way of the withholding in whole or in part of any relevant payment as definedin section 6(3) of the Tax Concessions Act (As Revised).

There are no other taxes likely to be material to the Company levied by the Governmentof the Cayman Islands save certain stamp duties which may be applicable, from time to time,on certain instruments executed in or brought within the jurisdiction of the Cayman Islands.The Cayman Islands are not party to any double tax treaties that are applicable to any paymentsmade by or to the Company.
