We refer to this report as the "iResearch Report." We also procured certain data included in this prospectus from QuestMobile, a third-party independent research firm.

Our Business

We enrich the everyday life of young generations in China.

We represent the iconic brand of online entertainment for the young generations in China. We provide high-quality content and an immersive entertainment experience, and have built our platform based on the strong emotional connections of our users to our content and communities. We started as a content community inspired by anime, comics and games, or ACG, and have evolved into a full-spectrum online entertainment world covering a wide array of genres and media formats, including videos, live broadcasting and mobile games. We have now become the welcoming home of diverse cultures and interests and destination for discovering cultural trends and phenomena for young generations in China. We rank No.1 in terms of monthly average time spent per device and monthly average visits per device among online video platforms, an integral part of online entertainment in China, on a monthly aggregate basis in 2017, according to QuestMobile. We believe China will become the world's largest online entertainment market in the future and our brand recognition and market leadership among the young generations in China position us well to capture the significant opportunities.

We have a young and culturally aspirational user base willing to invest in a high-quality entertainment experience. According to QuestMobile, as of December 31, 2017, approximately 81.7% of our user base were Generation Z, individuals born from 1990 to 2009 in China. They typically receive quality education and are technology savvy, with strong demand for culture products and avenues for self-expression and social interaction. In the fourth quarter of 2017, we had 71.8 million average monthly active users, an increase of 45.3% from 49.4 million in the same period of 2016. We believe our users will be the driving force and trend-setters of entertainment consumption in China as they grow with us.

We capture the hearts and minds of our users with superior content experience and carefully designed interactive features. Our user base has demonstrated strong engagement and loyalty to our communities. In 2017, the average daily time spent per active user on our mobile app was approximately 76.3 minutes, as compared to 72.2 minutes in 2016. We pioneered the "bullet chatting" feature, a live commenting function that has transformed the viewing experience by displaying thoughts and feelings of other audience viewing the same video. This signature feature fosters a highly interactive and enjoyable viewing experience and allows our users to benefit from the strong emotional bonds with other users who share similar aspiration and interests.

Our vibrant communities fuel the ever-growing supply of creative professional user generated content, or PUGC. We have developed a robust system and nurtured an encouraging community culture that respects and rewards content creators and motivates the creation of inspirational content. The average monthly number of our active content creators grew by 104% from approximately 100,200 in 2016 to approximately 204,100 in 2017. In addition to PUGC, our diversified content offerings include licensed videos, live broadcasting and mobile games. We focus on offering content that caters to the evolving and diversified interests of our users and our communities.

We attract our users with engaging content, retain users with our vibrant communities, and curate the right content to satisfy our users' entertainment needs. We have successfully developed an ecosystem comprised of highly-engaged users, talented content creators, as well as business partners, forming a virtuous cycle for monetization. We primarily generate revenues from mobile games, live broadcasting and online advertising. Our net revenues grew by 299% from RMB131.0 million (US$19.7 million) in 2015 to RMB523.3 million (US$78.7 million) in 2016, and grew by 467% from RMB305.7 million (US$45.9 million) for the nine months ended September 30, 2016 to RMB1,734.7 million (US$260.7 million) for the same period of 2017. We incurred net loss of RMB373.5 million (US$56.1 million) in 2015 and RMB911.5 million (US$137.0 million) in 2016. For the nine months ended September 30, 2017, we had net loss of RMB132.4 million (US$19.9 million), compared to net loss of RMB512.4 million (US$77.0 million) for the same period of 2016.

Our Industry

Online entertainment is a large and fast growing industry in China. According to the iResearch Report, China's online entertainment industry market reached RMB205.8 billion in 2016 and is expected to grow at a compound annual growth rate, or CAGR, of 29.6% to RMB752.7 billion in 2021. In particular, Generation Z, the demographic cohort in China of individuals born from 1990 to 2009, is redefining the online entertainment industry because this cohort of individuals have grown up in a unique socio-environment, especially in the following aspects: (i) consumption upgrades to address cultural needs, (ii) deep internet adoption in daily lives and (iii) strong desire for self-expression. According to the iResearch Report, the population of Generation Z has reached 328 million in 2016. Their market share contribution to the online entertainment industry in China in terms of dollar spending is expected to grow from 45.8% in 2014, to 54.8% in 2017 and further to 62.1% in 2020.

As traditional media outlets, which provide content covering limited themes and subjects through a simplex "one-way" form, can no longer satisfy the evolving entertainment needs, online entertainment powered by mobile internet and technology, diversified content and interactive features has become the mainstream media format. Quality content attracts and retains users, which in turn incentivize content providers to create more engaging content. This virtuous cycle propels the healthy development of the online entertainment industry. A large number of Generation Z are actively involved in content generation and promotion, rather than passive content viewing and consumption. According to the iResearch Report, as of the end of 2016, there were 636 million online entertainment consumers in China, who on average spent 1.4 hours every day on online entertainment. Among them, 282 million were Generation Z, and they on average spent more than 1.6 hours every day on online entertainment.

China's online entertainment industry has been expanding rapidly to meet the increasing demand of Generation Z for quality content. Such content covers a wide variety of themes, including anime and comics, game, music, fashion, lifestyle, technology, movie and television serial drama. Driven by the increasing demand on a diverse range of entertainment content, key sectors of the online entertainment industry, including video, games and live broadcasting, have been growing exponentially.

•: enhance our content offerings;
•: improve user experience on our platform;
•: further enhance our technologies and infrastructure; and
•: strengthen our monetization capabilities.

Our Challenges

Our ability to realize our mission and execute our strategies is subject to risks and uncertainties, including those relating to our ability to:

•: maintain our culture and brand image within our addressable user communities;
•: address the evolving entertainment needs of our users and provide quality content, products and services to attract and retain users;
•: successfully implement our monetization strategies and generate sustainable revenues and profit;
•: sustain our growth and the increased complexity of our business;
•: manage our costs and expenses;

Please see "Risk Factors" and other information included in this prospectus for a discussion of these and other risks and uncertainties that we face.

Corporate History and Structure

Our website was first launched in June 2009 and was officially named "bilibili" in January 2010. We commenced our commercial operations in 2011 and established Shanghai Hode Information Technology Co., Ltd., or Shanghai Hode, to expand our operations in May 2013. Subsequently, we obtained control over Shanghai Kuanyu Digital Technology Co., Ltd., or Shanghai Kuanyu, in July 2014 to further expand our operations.

We incorporated Bilibili Inc. under the laws of the Cayman Islands as our offshore holding company in December 2013. In February 2014, we established Hode HK Limited, or Hode HK, a wholly-owned Hong Kong subsidiary. In September 2014, Hode HK established a wholly-owned PRC subsidiary, Hode Shanghai Limited, which we refer to as Hode Technology or our WFOE in this prospectus.

As a result of our direct ownership in our WFOE and the variable interest entity contractual arrangements, we are regarded as the primary beneficiary of our VIEs. We treat them and their subsidiaries as our consolidated affiliated entities under U.S. GAAP, and have consolidated the financial results of these entities in our consolidated financial statements in accordance with U.S. GAAP.

The following diagram illustrates our corporate structure, including our principal subsidiaries and our VIEs and their respective principal subsidiaries, as of the date of this prospectus:

Notes:

(1): Rui Chen is a beneficial owner of the shares of Bilibili Inc. and holds 100% equity interests in Shanghai Kuanyu. He is also the chairman of our board of directors and our cheif executive officer.
(2): Rui Chen, Yi Xu, Qian Wei, Ni Li and Xi Cao are beneficial owners of the shares of Bilibili Inc. and hold 52.3%, 34.8%, 7.0%, 3.4% and 2.5% equity interests in Shanghai Hode, respectively. Among them, Mr. Chen, Mr. Xu and Ms. Li are also directors and officers of our company.

Implication of Being an Emerging Growth Company

As a company with less than US$1.07 billion in revenue for our last fiscal year, we qualify as an "emerging growth company" pursuant to the Jumpstart Our Business Startups Act of 2012, as amended, or the JOBS Act. An emerging growth company may take advantage of specified reduced reporting and other requirements compared to those that are otherwise applicable generally to public companies. These provisions include exemption from the auditor attestation requirement under Section 404 of the Sarbanes-Oxley Act of 2002 in the assessment of the emerging growth company's internal control over financial reporting. The JOBS Act also provides that an emerging growth company does not need to comply with any new or revised financial accounting standards until such date that a private company is otherwise required to comply with such new or revised accounting

standards. However, we have elected to "opt out" of this provision and, as a result, we will comply with new or revised accounting standards as required when they are adopted for public companies. This decision to opt out of the extended transition period under the JOBS Act is irrevocable.

We will remain an emerging growth company until the earliest of (a) the last day of the fiscal year during which we have total annual gross revenues of at least US$1.07 billion; (b) the last day of our fiscal year following the fifth anniversary of the completion of this offering; (c) the date on which we have, during the preceding three-year period, issued more than US$1.00 billion in non-convertible debt; or (d) the date on which we are deemed to be a "large accelerated filer" under the Securities Exchange Act of 1934, as amended, or the Exchange Act, which would occur if the market value of our ADSs that are held by non-affiliates exceeds US$700 million as of the last business day of our most recently completed second fiscal quarter. Once we cease to be an emerging growth company, we will not be entitled to the exemptions provided in the JOBS Act discussed above.

Non-GAAP Measures

We use EBITDA, adjusted EBITDA and adjusted net loss, each a non-GAAP financial measure, in evaluating our operating results and for financial and operational decision-making purposes.

provide useful information about our results of operations, enhance the overall understanding of our past performance and future prospects and allow for greater visibility with respect to key metrics used by our management in its financial and operational decision-making.

EBITDA, adjusted EBITDA and adjusted net loss should not be considered in isolation or construed as an alternative to loss from operations, net loss or any other measure of performance or as an indicator of our operating performance. Investors are encouraged to review the historical non-GAAP financial measures to the most directly comparable GAAP measures. EBITDA, adjusted EBITDA and adjusted net loss presented here may not be comparable to similarly titled measures presented by other companies. Other companies may calculate similarly titled measures differently, limiting their usefulness as comparative measures to our data. We encourage investors and others to review our financial information in its entirety and not rely on a single financial measure.

EBITDA represents net loss excluding depreciation, amortization, interest income and income tax. Adjusted EBITDA represents net loss excluding share-based compensation expenses, depreciation, amortization, interest income and income tax. The table below sets forth a reconciliation of our net loss to EBITDA and adjusted EBITDA for the periods indicated:

An investment in our ADSs involves significant risks. You should carefully consider all of the information in this prospectus, including the risks and uncertainties described below, before making an investment in our ADSs. Any of the following risks could have a material adverse effect on our business, financial condition and results of operations. In any such case, the market price of our ADSs could decline, and you may lose all or part of your investment.

We operate in a fast evolving industry, and we are in the early stage of our business. We cannot guarantee that our monetization strategies will be successfully implemented or generate sustainable revenues and profit.

We are in the early stage of our business, and our monetization model is evolving. We generate revenues primarily by providing our users with valuable content, such as mobile games and live broadcasting. We also generate revenues from advertising and other services. We cannot assure you that we can successfully implement the foregoing monetization strategies to generate sustainable revenues, or that we will be able to develop new monetization strategies to grow our revenues. If our strategic initiatives do not enhance our ability to monetize or enable us to develop new monetization approaches, we may not be able to maintain or increase our revenues or recover any associated costs. In addition, we may introduce new products and services to expand our revenue streams, including products and services with which we have little or no prior development or operating experience. If these new or enhanced products or services fail to engage users, content creators or business partners, we may fail to generate sufficient revenues to justify our investments and costs, and our business and operating results may suffer as a result.

We have incurred significant losses and we may continue to experience losses in the future.

We have incurred significant losses in the past. In 2015 and 2016 and the nine months ended September 30, 2017, respectively, we had loss from operations of RMB368.9 million, RMB894.7 million (US$134.5 million) and RMB162.2 million (US$24.4 million), and net loss of RMB373.5 million, RMB911.5 million (US$137.0 million) and RMB132.4 million (US$19.9 million). We also had cash used in operations of RMB191.9 million and RMB199.0 million (US$29.9 million) in 2015 and 2016, respectively. For the nine months ended September 30, 2017, we had cash provided by operations of RMB285.6 million (US$42.9 million). We cannot assure you that we will be able to generate profits or positive cash flow from operating activities in the future. Our ability to achieve profitability depends in large part on our ability to manage our costs and expenses. We intend to manage and control our costs and expenses as a proportion of our total revenues, but there can be no assurance that we will achieve this goal. We may experience losses in the future due to our continued investments in technology, talent, content and other initiatives. In addition, our ability to achieve and sustain profitability is affected by various factors, some of which are beyond our control, such as changes in macroeconomic and regulatory environment or competitive dynamics in the industry. Accordingly, you should not rely on our financial results of any prior period as an indication of our future performance.

If we fail to anticipate user preferences and provide products and services to attract and retain users, or if we fail to keep up with rapid changes in technologies and their impact on user behavior, we may not be able to attract sufficient user traffic to remain competitive, and our business and prospects may be materially and adversely affected.

Our ability to retain, grow and engage our user base depends heavily on our ability to provide a superior user experience. We must offer quality content covering a wide range of interests and formats, introduce successful new products and services, develop user-friendly platform features, and push effective content feeds recommendations. In particular, we must encourage content creators to upload

more appealing PUGC and source more popular licensed content. We must also keep providing our users with features and functions that could enable superior content viewing and social interaction experience. If we are unable to provide a superior user experience, our user base and user engagement may decline, which may materially and adversely affect our business and growth prospects.

We maintain a large content library primarily consisting of PUG videos and licensed content, and are developing new features to attract and retain our users. In order to expand our content library, we must continue to work with our content creators and incentivize them to produce content that reflects cultural trends and maintain good business relationships with licensors of premium copyrighted content to renew our licenses and source new professionally produced content. Our content creators and licensors may choose to work with other large online video platforms to distribute their content if such platforms can offer better products, services or terms than we do. We cannot assure you that we will be able to attract our content creators to upload their content to our platform or renew or enter into license agreements on commercially reasonable terms with our licensors or at all.

In addition, the industry in which we operate is characterized by rapidly changing technologies and changing user expectations. To remain competitive, we must be able to adapt to these changes and innovate in response to evolving user expectations. Developing and integrating new content, products, services and technologies into our existing platform could be expensive and time-consuming, and these efforts may not yield the benefits we expect. If we fail to develop new products, services or innovative technologies on a timely basis, or our new products, services or technologies are not accepted by our users, our business, financial performance and prospects could be materially and adversely affected. We cannot assure you that we can anticipate user preferences and industry changes and respond to such changes in a timely and effective manner.

Our business depends on our ability to provide users with interesting and useful content, which in turn depends on the content contributed by the content creators on our platform.

The quality of the content offered on our platform and our users' level of engagement are critical to our success. In order to attract and retain users and compete effectively, we must offer interesting and useful content and enhance our users' viewing experience. It is vital to our operations that we remain sensitive to and responsive to evolving user preferences and offer content that appeals to our users and members. In 2017, PUG video views accounted for 85.5% of our total video views, as compared to 74.5% in 2016. Thus far, we have been generally able to encourage our content creators to create and upload PUGC that is appealing to our users. We have also been providing our content creators with support and guidance in various forms, including technical support for content distribution, editing and uploading. However, we cannot assure you that our content creators can contribute to create popular PUGC for our platform. If our content creators cease to contribute content, or their uploaded content fails to attract or retain our users, we may experience a decline in user traffic and user engagement. If the number of users or the level of user engagement declines, we may suffer a reduction in revenue.

We may not be able to effectively manage our growth and the increased complexity of our business, which could negatively impact our brand and financial performance.

We have experienced rapid growth since our inception in 2011. The number of our average MAUs grew by 45.3% from 49.4 million in the fourth quarter of 2016 to 71.8 million in the fourth quarter of 2017. As we grow our user base and increase the level of user engagement, we may incur increasing costs, such as licensing fees and royalties for licensed content and hosts' compensation to further expand our content library to meet the growing and diversified demands of our users. If such expansion is not properly managed, it may adversely affect our financial and operating resources without achieving the desired effects.

As we only have a limited history of operating our business at its current scale, it is difficult to evaluate our current business and future prospects, including our ability to grow in the future. In addition, our costs and expenses may increase rapidly as we expand our business and continue to invest in our infrastructure to enhance the performance and reliability of our platform. For example, we may increase our investment in servers and bandwidth to maintain our quality user experience while sustaining the growth of user base. Continued growth could also strain our ability to maintain reliable service levels for our users, content creators and business partners, develop and improve our operational, financial, legal and management controls, and enhance our reporting systems and procedures. Our costs and expenses may grow faster than our revenues and may be greater than what we anticipate. If we are unable to generate adequate revenues and to manage our costs and expenses, we may continue to incur losses in the future and may not be able to achieve or subsequently maintain profitability. Managing our growth will require significant expenditures and the allocation of valuable management resources. If we fail to achieve the necessary level of efficiency in our organization as it grows, our business, operating results and financial condition could be harmed.

If the content contained within videos, games and other content formats on our platform is deemed to violate any PRC laws or regulations, our business, financial condition and results of operations may be materially and adversely affected.

The PRC government and regulatory authorities have adopted regulations governing content contained within videos, games, and other information over the internet. Under these regulations, internet content providers are prohibited from posting or displaying over the internet content that, among other things, violates PRC laws and regulations, impairs the national dignity of China or the public interest, or is obscene, superstitious, fraudulent, violent or defamatory. Internet content providers are also prohibited from displaying content that may be deemed by relevant government authorities as "socially destabilizing" or leaking "state secrets" of China. The PRC government and regulatory authorities strengthen the regulations on internet content from time to time, such as the Opinion on Strictly Regulating Online Game Market Management jointly adopted by a few authorities on December 18, 2017, which regulates illegal and improper content in online games. Failure to comply with these requirements may result in the revocation of licenses to provide internet content or other licenses, the closure of the concerned websites and reputational harm. The website operator may also be held liable for such censored information displayed on or linked to their website.

In addition to licensed content provided by copyright owners, we allow our users to upload content to our platform. Our users can upload all types of content including user-created and professionally produced content and certain graphical files for the purpose of updating user biographies and content covers. Currently only registered users who have passed our membership exam are allowed to upload content to our platform. We maintain two levels of content management and review procedures to monitor the content uploaded to our platform to ensure that no content that may be deemed to be prohibited by government rules and regulations is posted and to promptly remove any infringing content. Our content screening team is dedicated to screening and monitoring the content uploaded on our platform on a 24-hour, 7-day basis. For more details relating to our content monitoring procedures, see "Business—Content Management and Review." However, there can be no assurance that we can identify all the videos or other content that may violate relevant laws and regulations due to the large amount of content uploaded by our users every day.

Failure to identify and prevent illegal or inappropriate content from being uploaded on our platform may subject us to liability. To the extent that PRC regulatory authorities find any content on our platform objectionable, they may require us to limit or eliminate the dissemination of such content on our platform in the form of take-down orders or otherwise. In addition, PRC laws and regulations are subject to interpretation by the relevant authorities, and it may not be possible to determine in all cases the types of content that could result in our liability as a platform operator. In the past, we were

subject to penalties by PRC regulatory authorities due to our failure to comply with these requirements. For example, we were subject to a fine of RMB21,000 in September 2017 from a local counterpart of the MOC primarily for having inappropriate content in certain games operated on our platform. We also may face liability for copyright or trademark infringement, fraud and other claims based on the nature and content of the materials that are delivered, shared or otherwise accessed through or displayed on our platform.

We derive a substantial majority of our revenues from mobile games. If we fail to launch new games or release upgrades to existing games to attract new players and retain existing players, our business and operating results will be materially and adversely affected.

We derive a substantial majority of our revenues from mobile games, and we derive a significant portion of mobile game revenues from a limited number of games. We offer mobile games from third-party game developers and publishers on our platform either on an exclusive or non-exclusive basis. Therefore, we must maintain good relationships with our third-party game developers and copyright owners to obtain access to new popular games on reasonable commercial terms. We may not be able to maintain or renew these agreements on acceptable terms or at all. In such event, we may be unable to continue offering these popular mobile games, and our operating results will be adversely affected. In addition, if our users decide to access these games through our competitors, or if they prefer other mobile games operated by our competitors, our operating results could be materially and adversely affected. In addition, if we fail to launch new games or release upgrades to existing games in a timely manner, or if our games do not achieve expected popularity, we may lose players of our games, which could materially and adversely impact our business. Even in the event that we succeed in launching new games, the new games may divert players away from the existing games on our platform, which may increase player churn and reduce revenues from our existing games.

In addition, the revenue model we adopt for online games may not remain effective, which may cause us to lose players and materially and adversely affect our business, financial condition and results of operations. We derive substantially all of the mobile games revenues from the sale of in-game virtual items. However, we may not be able to continue to successfully implement this model. Furthermore, PRC regulators have been implementing regulations designed to reduce the amount of time that youth spend playing online games. See "Regulation—Regulations Related to Anti-fatigue System, Real-name Registration System and Parental Guardianship Project." A revenue model that does not charge for playing time may be viewed by the PRC regulators as inconsistent with this goal. On the other hand, if we were to start charging for playing time, we may lose our players, and our financial condition and results of operations may be materially and adversely affected.

We face significant competition, primarily from companies that operate online entertainment platforms in China, and we compete with these companies for users, content providers and advertisers.

We face significant competition primarily from companies that operate online entertainment platforms in China designed to engage users, especially Generation Z, and capture their time spent on mobile devices and online. In particular, our competitors mainly include large online video streaming platforms, social media platforms and other platforms offering video products. Some of our competitors have longer operating histories and significantly greater financial resources than we do, and in turn may be able to attract and retain more users, content partners and advertisers. Our competitors may compete with us in a variety of ways, including by obtaining exclusive online distribution rights for popular content, conducting brand promotions and other marketing activities, and making acquisitions. If any of our competitors provides comparable or better user experience, our user traffic could decline significantly. We have exclusive distribution rights only for certain PUGC on our platform. Our content creators are generally free to post their content on our competitors' platforms, which may divert user traffic from our platform, and adversely affect our user traffic and thus our operations.

We believe that our ability to compete effectively depends upon many factors, some of which are beyond our control, including:

Increases in the costs of content on our platform may have an adverse effect on our business, financial condition and results of operations.

We need to acquire popular content to provide our users with an engaging and satisfying viewing experience, and our acquisition of such content depends on our ability to retain our content creators and hosts of our live broadcasting program. As our business develops, we may incur increasing revenue-sharing costs to compensate our content creators and hosts of our live broadcasting program. Increases in market prices for licensed content may also have an adverse effect on our business, financial condition and results of operations. If we are not able to procure licensed content at commercially acceptable costs, our business and results of operations will be adversely impacted. In addition, if we are unable to generate sufficient revenues to outpace the increase in market prices for licensed content, our business, financial condition and results of operations may be adversely affected.

We may be subject to intellectual property infringement claims or other allegations, which could result in material damage to our reputation and brand image, payment of substantial damages, penalties and fines, removal of relevant content from our platform or seeking license arrangements which may not be available on commercially reasonable terms.

Content posted on our platform may expose us to allegations by third parties of infringement of intellectual property rights, unfair competition, invasion of privacy, defamation and other violations of third-party rights. We have been involved in litigation based on allegations of infringement of third-party copyright due to the content available on our platform. We are currently involved in approximately 100 lawsuits based on allegations of infringement of third-party copyright due to the content posted on our platform, none of which is material to our company on an individual basis.

Our failure to identify unauthorized videos posted on our platform may subject us to claims of infringement of third-party intellectual property rights or other rights. Although we maintain content management and review procedures to monitor the content uploaded to our platform, due to the large number of videos uploaded, we may not be able to identify all content that may infringe on third-party

rights. Such failure may subject us to potential claims and lawsuits, defending of which may impose a significant burden on our management and employees, and there can be no assurance that we will obtain final outcomes that are favorable to us. In addition, we may be subject to administrative actions brought by the National Copyright Administration of China or its local branches for alleged copyright infringement.

The validity, enforceability and scope of protection of intellectual property rights in internet-related industries, particularly in China, are uncertain and still evolving. As we face increasing competition and as litigation becomes a more common way to resolve disputes in China, we face a higher risk of being the subject of intellectual property infringement claims. Under relevant PRC laws and regulations, online service providers which provide storage space for users to upload works or links to other services or content could be held liable for copyright infringement under various circumstances, including situations where an online service provider knows or should reasonably have known that the relevant content uploaded or linked to on its platform infringes the copyrights of others and the provider realizes economic benefits from such infringement activities. In certain cases in China, the courts have found an online service provider to be liable for the copyrighted content posted by users which was accessible from and stored on such provider's servers.

Although we have not been subject to claims or lawsuits outside China, we may become subject to copyright laws in other jurisdictions, such as the United States, by virtue of our listing in the United States, the ability of users to access our videos from the United States and other jurisdictions, the ownership of our ADSs by investors, and the extraterritorial application of foreign law by foreign courts or otherwise. In addition, as a publicly listed company, we may be exposed to increased risk of litigation. If a claim of infringement brought against us in the United States or other jurisdictions is successful, we may be required to (i) pay substantial statutory or other damages and fines, (ii) remove relevant content from our platform, or (iii) enter into royalty or license agreements which may not be available on commercially reasonable terms or at all.

In addition, although we have required our users to post only legally compliant and inoffensive materials and have set up screening procedures, our screening procedures may fail to screen out all potentially offensive or non-compliant user-generated content and, even if properly screened, a third party may still find user-generated content posted on our platform offensive and take action against us in connection with the posting of such content. We may also face litigation or administrative actions for defamation, negligence or other purported injuries resulting from the content we provide or the nature of our services. Such litigations and administrative actions, with or without merit, may be expensive and time-consuming, result in significant diversion of resources and management attention from our operations, and adversely affect our brand image and reputation.

Furthermore, our app has been, and may again be taken down temporarily from Apple app store or other apps markets for copyright reasons, and we may be subject to copyright infringement claims brought by our competitors, which, malicious or not, may be time-consuming to defend and disrupting to our operations.

We may not be able to prevent others from unauthorized use of our intellectual property, which could harm our business and competitive position.

We have invested significant resources to develop our own intellectual property and acquire licenses to use and distribute the intellectual property of others on our platform. Failure to maintain or protect these rights could harm our business. In addition, any unauthorized use of our intellectual property by third parties may adversely affect our current and future revenues and our reputation.

Implementation and enforcement of PRC intellectual property-related laws have historically been deficient and ineffective. Accordingly, protection of intellectual property rights in China may not be as effective as in the United States or other developed countries. Furthermore, policing unauthorized use

of proprietary technology is difficult and expensive. We rely on a combination of patent, copyright, trademark and trade secret laws and restrictions on disclosure to protect our intellectual property rights. Despite our efforts to protect our proprietary rights, third parties may attempt to copy or otherwise obtain and use our intellectual property or seek court declarations that they do not infringe upon our intellectual property rights. We cannot assure you that the steps we have taken will prevent misappropriation of our intellectual property. From time to time, we may have to resort to litigation to enforce our intellectual property rights, which could result in substantial costs and diversion of our resources.

Many of our products and services contain open source software, which may pose particular risks to our proprietary software, products and services in a manner that negatively affects on our business.

We use open source software in our products and services and will use open source software in the future. There is a risk that open source software licenses could be construed in a manner that imposes unanticipated conditions or restrictions on our ability to provide or distribute our products or services. Additionally, we may face claims from third parties claiming ownership of, or demanding release of, the open source software or derivative works that we developed using such software. These claims could result in litigation and could require us to make our software source code freely available, purchase a costly license or cease offering the implicated products or services unless and until we can re-engineer them to avoid infringement. This re-engineering process could require significant additional research and development resources, and we may not be able to complete it successfully.

Furthermore, because any software source code we contribute to open source projects is publicly available, our ability to protect our intellectual property rights with respect to such software source code may be limited or lost entirely. As a result, we may be unable to prevent our competitors or others from using such software source code contributed by us.

Our live broadcasting business is still in its early stage of monetization, and we face intense competition for users and hosts, as well as strict regulatory supervision by government authorities.

Our live broadcasting business is still in its early stage. We face significant competition in the live broadcasting business for both users and hosts. The live broadcasting program on our platform primarily focuses on interest areas such as animation, comics and games, animals and pets, art and lifestyle. We cannot assure you that such content will continue to attract new users and retain existing ones. We have entered into exclusive cooperation agreements with certain popular hosts on our platform. We may not be able to maintain or renew these agreements on acceptable terms or at all. In such event, we may be unable to retain these popular hosts on our platform, and our operating results will be adversely affected. In addition, the costs attributed to hosts' compensation have increased significantly in China during the past few years for companies that provide such services. If we are unable to generate sufficient revenues to outpace the increase in such compensation, we may lose opportunities to retain the popular hosts on our platform and thus incur more losses. In addition, the compensation we pay to the hosts could significantly increase our cost of revenues and materially adversely affect our margins, financial condition and results of operations.

In addition, our live broadcasting services may be abused by hosts and other users. We have an internal control system in place to review and monitor live broadcasting streams and will shut down those streams that may violate PRC laws and regulations. However, we may not identify all such streams and content. Failure to comply with applicable laws and regulations may result in the revocation of our licenses to provide internet content or other licenses, the closure of the concerned platforms and reputational harm. We may also be held liable for such censored information displayed on our platform.

We have a unique community culture that is vital to our success. Our operations may be materially and adversely affected if we fail to maintain our culture and brand image within our addressable user communities.

Our users have developed a unique community culture that distinguishes us from other online content providers. Our users come to our platform for creative content covering a wide array of cultures and interests as well as for strong, vibrant and safe communities. We believe that maintaining and promoting such community culture is critical to retaining and expanding our user base. We have taken multiple initiatives to preserve our community culture and values, such as requiring users to pass a membership exam before they are allowed to send B-chats and utilize other interactive functions on our platform, and temporarily blocking or permanently deleting accounts of users who posted inappropriate content or comments.

Despite our efforts, we may be unable to maintain and foster our unique community culture and cease to be the preferred platform for our target users and content creators. As our user base is expanding, we may have difficulties in guiding our new users to honor and abide by our community values despite the initiatives we have adopted and may adopt in the future. In such event, our user engagement and loyalty may suffer, which would in turn negatively affect user traffic and our attractiveness to other customers and partners. In addition, frictions among our users and inflammatory comments posted by internet trolls may damage our community culture and brand image, which would be detrimental to our operations. Historically, some incidents of intense frictions among our users who belonged to different micro-interests and fans groups disrupted our operations.

If we fail to develop effective advertising products and system, retain existing advertisers or attract new advertisers to advertise on our platform, or if we are unable to collect accounts receivable from the advertisers or advertising agencies in a timely manner, our financial condition, results of operations and prospects may be materially and adversely affected.

We generate a portion of our revenues from advertising. We enter into contracts with both advertisers and third-party advertising agencies, and the financial soundness of these customers may affect our collection of accounts receivable. We make a credit assessment of the advertiser and advertising agency to evaluate the collectability of the advertising service fees before entering into an advertising contract. However, we cannot assure you that we are or will be able to accurately assess the creditworthiness of each advertiser or advertising agency, and any inability of advertisers or advertising agencies to pay us in a timely manner may adversely affect our liquidity and cash flows.

Our ability to generate and maintain our advertising revenues depends on a number of factors, including the maintenance and enhancement of our brand, the scale, engagement and loyalty of our users and the market competition on advertising prices. We cannot assure you that we will be able to retain existing advertisers or advertising agencies or attract new ones. If we fail to retain and enhance our relationships with third-party advertising agencies or advertisers themselves, our business, results of operations and prospects may be adversely affected.

We may not be successful in developing relationships with key participants in the mobile industry or in developing services that operate effectively with these operating systems, networks, devices and standards.

We make our products and services available across a variety of operating systems, mainly on mobile devices and personal computers. As mobile usage accelerates, we expect to generate a large portion of our business and revenues from mobile. If we are unable to successfully capture and retain the growing number of users that access internet services through mobile devices, or if we are slower than our competitors in developing attractive products and services adaptable for mobile devices, we may fail to capture a significant share or an increasingly important portion of the market or may lose

existing users. In addition, even if we are able to retain the increasing number of mobile users, we may not be able to successfully monetize them in the future.

We depend on the interoperability of our products and services with popular devices, desktop and mobile operating systems and web browsers that we do not control, such as Windows, Mac OS, Android, iOS, and others. Any changes in devices or their systems that degrade the functionality of our products and services or give preferential treatment to competitive products or services could adversely affect usage of our products and services. We may not be successful in developing relationships with key participants in the mobile industry or in developing services that operate effectively with these operating systems, networks, devices and standards. Further, if the number of systems, networks and devices for which we develop our products and services increases, it will result in an increase in our costs and expenses, and adversely affect our gross margin and results of operation.

Any malfunction, capacity constraint or operation interruption for any extended period may have an adverse impact on our business.

Our ability to provide superior user experience on our platform depends on the continuous and reliable operation of our IT systems. We cannot assure you that we will be able to procure sufficient bandwidth in a timely manner or on acceptable terms or at all. Failure to do so may significantly impair user experience on our platform and decrease the overall effectiveness of our platform to users, content providers and advertisers. Our IT systems and proprietary content distribution network are vulnerable to damage or interruption as a result of fires, floods, earthquakes, power losses, telecommunications failures, undetected errors in software, computer viruses, hacking and other attempts to harm our IT systems. Disruptions, failures, unscheduled service interruptions or a decrease in connection speeds could damage our reputation and cause our users, content providers and advertisers to migrate to our competitors' platforms. If we experience frequent or persistent service disruptions, whether caused by failures of our own IT systems or those of third-party service providers, our user experience may be negatively affected, which in turn may have a material and adverse effect on our reputation and business. We cannot assure you that we will be successful in minimizing the frequency or duration of service interruptions. As the number of our users increases and our users generate more content on our platform, we may be required to expand and adapt our technology and infrastructure to reliably store and process content. It may become increasingly difficult to maintain and improve the performance of our platform, especially during peak usage times, as our services become more complex and our user traffic increases.

Any compromise of the cyber security of our platform could materially and adversely affect our business, operations and reputation.

Our products and services involve the storage and transmission of users' and other customers' information, and security breaches expose us to a risk of loss of this information, litigation and potential liability. We experience cyber-attacks of varying degrees from time to time, and we have been able to rectify attacks without significant impact to our operations in the past. 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 other customers to disclose sensitive information in order to gain access to our data or our users' or other customers' data or accounts, or may otherwise obtain access to such data or accounts. Because the techniques used to obtain unauthorized access, disable or degrade service or sabotage systems change frequently and often are not recognized until launched against a target, we may be unable to anticipate these techniques or to implement adequate preventative measures. If an actual or perceived breach of our security occurs, the market perception of the effectiveness of our security measures could be harmed, we could lose users and other customers, and may be exposed to significant legal and financial risks, including legal claims and regulatory fines and penalties. Any of these actions could have a material and adverse effect on our business, reputation and results of operations.

Undetected programming errors or flaws or failure to maintain effective customer service could harm our reputation or decrease market acceptance of our products and services, which would materially and adversely affect our results of operations.

The video programs, including advertising video programs, on our platform may contain programming errors that may only become apparent after their release. We generally have been able to resolve such flaws and errors. However, we cannot assure you that we will be able to detect and resolve all these programming errors effectively. Undetected programming errors could adversely affect our user experience and market acceptance.

Our software has contained, and may now or in the future contain, errors, bugs or vulnerabilities. Any errors, bugs or vulnerabilities discovered in our code after release could result in damage to our reputation, loss of users, loss of content providers, loss of revenue or liability for damages, any of which could adversely affect our business and operating results.

Privacy concerns relating to our products and services and the use of user information could damage our reputation, deter current and potential users and customers from using our products.

We collect personal data from our users in order to better understand our users and their needs for the purpose of our content feeds recommendation and to help our advertisement customers target specific demographic groups. Concerns about the collection, use, disclosure or security of personal information or other privacy-related matters, even if unfounded, could damage our reputation, cause us to lose users and other customers and adversely affect our results of operations. While we strive to comply with applicable data protection laws and regulations, as well as our privacy policies pursuant to our terms of use and other obligations we may have with respect to privacy and data protection, any failure or perceived failure to comply with these laws, regulations or policies may result in inquiries and other proceedings or actions against us by government agencies or others, as well as negative publicity and damage to our reputation and brand, each of which could cause us to lose users and customers and have an adverse effect on our business and results of operations.

Any systems failure or compromise of our security that results in the unauthorized access to or release of our users' or other customers' data could significantly limit the adoption of our products and services, as well as harm our reputation and brand and, therefore, our business. We expect to expend significant resources to protect against security breaches. The risk that these types of events could seriously harm our business is likely to increase as we expand the number of services we offer and increase the size of our users base.

Our practices may become inconsistent with new laws or regulations concerning data protection, or the interpretation and application of existing consumer and data protection laws or regulations, which is often uncertain and in flux. If so, in addition to the possibility of fines, this could result in an order requiring that we change our practices, which could have an adverse effect on our business and operating results. Complying with new laws and regulations could cause us to incur substantial costs or require us to change our business practices in a manner materially adverse to our business.

We utilize payment collection channels to collect proceeds from our paying users' purchases. Any failure by those payment collection channels to process payments effectively and securely may materially and adversely affect our revenue realization and brand recognition.

We depend on the billing and payment systems of third parties such as online third-party payment processors to maintain accurate records of payments of sales proceeds by paying users and collect such payments. We receive periodic statements from these third parties which indicate the aggregate amount of fees that were charged to paying users of our products and services. Our business and results of operations could be adversely affected if these third parties fail to accurately account for or calculate the revenues generated from the sales of our products and services. If there are security breaches or

failure or errors in the payment process of these third parties, user experience may be affected and our business results may be negatively impacted.

Failure to timely collect our receivables from third parties whose billing and payment systems we use and third-party payment processors may adversely affect our cash flows. Our third-party payment processors may from time to time experience cash flow difficulties. Consequently, they may delay their payments to us or fail to pay us at all. Any delay in payment or inability of current or potential third-party payment processors to pay us may significantly harm our cash flow and results of operations.

We also do not have control over the security measures of our third-party payment service providers, and security breaches of the online payment systems that we use could expose us to litigation and possible liability for failing to secure confidential customer information and could, among other things, damage our reputation and the perceived security of all of the online payment systems that we use. If a well-publicized internet security breach were to occur, users concerned about the security of their online payments may become reluctant to purchase our products through payment service providers even if the publicized breach did not involve payment systems or methods used by us. In addition, billing software errors could damage user confidence in these payment systems. If any of the above were to occur and damage our reputation or the perceived security of the payment systems we use, we may lose paying users as they may be discouraged from purchasing products or services on our platform, which may have an adverse effect on our business and results of operations.

Our success depends on the efforts of our key employees, including our senior management members and other technology talents. If we fail to hire, retain and motivate our key employees, our business may suffer.

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 officers or other key employees could harm our business. Competition for qualified talent in China is intense, particularly in the internet and technology industries. Our future success depends on our ability to attract a large number of qualified employees and retain existing key employees. If we are unable to do so, our business and growth may be materially and adversely affected and the trading price of our ADSs could suffer. Our need to significantly increase the number of our qualified employees and retain key employees may cause us to materially increase compensation-related costs, including stock-based compensation.

We have granted, and may continue to grant, options and other types of awards under our share incentive plan, which may result in increased share-based compensation expenses.

We adopted a global share incentive plan in 2014, which we refer to as the Global Share Plan in this prospectus, for the purpose of granting share-based compensation awards to employees, directors and consultants to incentivize their performance and align their interests with ours. We recognize expenses in our consolidated financial statements in accordance with U.S. GAAP. Under the Global Share Plan, we are authorized to grant options and other types of awards. As of the date of this prospectus, the maximum aggregate number of ordinary shares which may be issued pursuant to all awards under the Global Share Plan is 19,880,315 ordinary shares, subject to amendment. As of the date of this prospectus, awards to purchase 19,409,209 ordinary shares under the Global Share Plan have been granted and outstanding, excluding awards that were forfeited or cancelled after the relevant grant dates. Some of our outstanding awards set the completion of an initial public offering of our ordinary shares as performance condition for vesting. As a result, a number of awards will become vested once we complete this offering, and we will then record additional share-based compensation expense on the completion date of this offering. As of September 30, 2017, our unrecognized share-based compensation expenses relating to unvested awards amounted to RMB328.8 million (US$49.5 million).

If we fail to implement and maintain an effective system of internal controls to remediate our material weakness over financial reporting, we may be unable to accurately report our results of operations, meet our reporting obligations or prevent fraud, and investor confidence and the market price of our ADSs may be materially and adversely affected.

Prior to this offering, we were a private company with limited accounting personnel and other resources with which to address our internal controls and procedures. Our management has not completed an assessment of the effectiveness of our internal control over financial reporting, and our independent registered public accounting firm has not conducted an audit of our internal control over financial reporting. In auditing our consolidated financial statements for the fiscal year ended December 31, 2016, we and our independent registered public accounting firm identified one material weakness in our internal control over financial reporting as well as other control deficiencies as of December 31, 2016, in accordance with the standards established by the Public Company Accounting Oversight Board of the United States (PCAOB).

The material weakness identified related to our lack of sufficient resources regarding financial reporting and accounting personnel with understanding of U.S. GAAP to address complex U.S. GAAP technical accounting issues, related disclosures in accordance with U.S. GAAP and financial reporting requirements set forth by the SEC.

Upon the completion of this offering, we will become a public company in the United States subject to the Sarbanes-Oxley Act of 2002. Section 404 of the Sarbanes-Oxley Act of 2002, will require that we include a report of management on our internal control over financial reporting in our annual report on Form 20-F beginning with our annual report for the fiscal year ending December 31, 2018. In addition, once we cease to be an "emerging growth company" as such term is defined in the JOBS Act, our independent registered public accounting firm must attest to and report on the effectiveness of our internal control over financial reporting. Our management may conclude that our internal control over financial reporting is not effective. Moreover, even if our management concludes that our internal control over financial reporting is effective, our independent registered public accounting firm, after conducting its own independent testing, may issue a report that is qualified if it is not satisfied with our internal controls or the level at which our controls are documented, designed, operated or reviewed, or if it interprets the relevant requirements differently from us. In addition, after we become a public company, our reporting obligations may place a significant strain on our management, operational and financial resources and systems for the foreseeable future. We may be unable to timely complete our evaluation testing and any required remediation.

During the course of documenting and testing our internal control procedures, in order to satisfy the requirements of Section 404 of the Sarbanes-Oxley Act of 2002, we may identify other weaknesses and deficiencies in our internal control over financial reporting. In addition, if we fail to maintain the adequacy of our internal control over financial reporting, as these standards are modified, supplemented or amended from time to time, we may not be able to conclude on an ongoing basis that we have effective internal control over financial reporting in accordance with Section 404 of the Sarbanes-Oxley Act of 2002. Generally, if we fail to achieve and maintain an effective internal control environment, we could suffer material misstatements in our financial statements and fail to meet our reporting obligations, which would likely cause investors to lose confidence in our reported financial information. This could in turn limit our access to capital markets, harm our results of operations, and lead to a decline in the trading price of our ADSs. Additionally, ineffective internal control over financial reporting could expose us to increased risk of fraud or misuse of corporate assets and subject us to potential delisting from the stock exchange on which we list, regulatory investigations and civil or criminal sanctions.

We rely on certain key operating metrics to evaluate the performance of our business, and real or perceived inaccuracies in such metrics may harm our reputation and negatively affect our business.

We rely on certain key operating metrics, such as MAU, to evaluate the performance of our business. Our operating metrics may differ from estimates published by third parties or from similarly titled metrics used by other companies due to differences in methodology and assumptions. We calculate these operating metrics using internal company data that have not been independently verified. If we discover material inaccuracies in the operating metrics we use, or if they are perceived to be inaccurate, our reputation may be harmed and our evaluation methods and results may be impaired, which could negatively affect our business. If investors make investment decisions based on operating metrics we disclose that are inaccurate, we may also face potential lawsuits or disputes.

The insurance industry in China is still in an early stage of development, and insurance companies in China currently offer limited business-related insurance products. We do not maintain business interruption insurance or general third-party liability insurance, nor do we maintain property insurance, product liability insurance or key-man insurance. We consider our insurance coverage to be reasonable in light of the nature of our business and the insurance products that are available in China and in line with the practices of other companies in the same industry of similar size in China, but we cannot assure you that our insurance coverage is sufficient to prevent us from any loss or that we will be able to successfully claim our losses under our current insurance policies on a timely basis, or at all. If we incur any loss that is not covered by our insurance policies, or the compensated amount is significantly less than our actual loss, our business, financial condition and results of operations could be materially and adversely affected.

We face risks related to natural disasters, health epidemics and other outbreaks, which could significantly disrupt our operations.

Our business could be adversely affected by the effects of epidemics. In recent years, there have been breakouts of epidemics in China and globally. Our operations could be disrupted if one of our employees is suspected of having H1N1 flu, avian flu or another epidemic, since it could require our employees to be quarantined and/or our offices to be disinfected. In addition, our results of operations could be adversely affected to the extent that the outbreak harms the PRC economy in general and the mobile internet industry in particular.

We are also vulnerable to natural disasters and other calamities. Although we have servers that are hosted in an offsite location, our backup system does not capture data on a real-time basis and we may be unable to recover certain data in the event of a server failure. We cannot assure you that any backup systems will be adequate to protect us from the effects of fire, floods, typhoons, earthquakes, power loss, telecommunications failures, break-ins, war, riots, terrorist attacks or similar events. Any of the foregoing events may give rise to server interruptions, breakdowns, system failures, technology platform failures or internet failures, which could cause the loss or corruption of data or malfunctions of software or hardware as well as adversely affect our ability to provide services on our platform.

Certain of our leasehold interests in leased properties have not been registered with the relevant PRC governmental authorities as required by relevant PRC laws. The failure to register leasehold interests may expose us to potential fines.

We have not registered certain of our lease agreements with the relevant government authorities. Under the relevant PRC laws and regulations, we may be required to register and file with the relevant government authority executed leases. The failure to register the lease agreements for our leased properties will not affect the validity of these lease agreements, but the competent housing authorities

may order us to register the lease agreements in a prescribed period of time and impose a fine ranging from RMB1,000 to RMB10,000 for each non-registered lease if we fail to complete the registration within the prescribed timeframe.

If the PRC government finds that the agreements that establish the structure for operating our businesses in China do not comply with PRC regulations on foreign investment in internet and other related businesses, or if these regulations or their interpretation change in the future, we could be subject to severe penalties or be forced to relinquish our interests in those operations.

PRC laws and regulations impose certain restrictions or prohibitions on foreign ownership of companies that engage in internet and other related businesses, including the provision of internet content and online game operations. Specifically, foreign ownership of an internet content provider may not exceed 50%, and the major foreign investor is required to have a record of good performance and operating experience in managing value-added telecommunications business. We are a company registered in the Cayman Islands and Hode Technology (our WFOE) is considered a foreign-invested enterprise. To comply with PRC laws and regulations, we conduct our business in China mainly through Shanghai Kuanyu and Shanghai Hode (our VIEs) and their respective subsidiaries, based on a series of contractual arrangements by and among Hode Technology, our VIEs, and their shareholders. As a result of these contractual arrangements, we exert control over our consolidated affiliated entities and consolidate their financial results in our financial statements under U.S. GAAP. Our consolidated affiliated entities hold the licenses, approvals and key assets that are essential for our operations.

In the opinion of our PRC counsel, Commerce & Finance Law Offices, based on its understanding of the relevant PRC laws and regulations, each of the contracts among Hode Technology, our VIEs and their shareholders is valid, binding and enforceable in accordance with its terms. However, we have been further advised by our PRC counsel that there are substantial uncertainties regarding the interpretation and application of current or future PRC laws and regulations. Thus, the PRC government may ultimately take a view contrary to the opinion of our PRC counsel. If we are found in violation of any PRC laws or regulations or if the contractual arrangements among Hode Technology, our VIEs and their shareholders are determined as illegal or invalid by the PRC court, arbitral tribunal or regulatory authorities, the relevant governmental authorities would have broad discretion in dealing with such violation, including, without limitation:

The imposition of any of these penalties may result in a material and adverse effect on our ability to conduct our business operations. In addition, if the imposition of any of these penalties causes us to

lose the rights to direct the activities of our consolidated affiliated entities or the right to receive their economic benefits, we would no longer be able to consolidate their financial results.

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

Due to PRC restrictions or prohibitions on foreign ownership of internet and other related businesses in China, we operate our business in China through our VIEs and their subsidiaries, in which we have no ownership interest. We rely on a series of contractual arrangements with our VIEs and their shareholders, including the powers of attorney, to control and operate business of our consolidated affiliated entities. These contractual arrangements are intended to provide us with effective control over our consolidated affiliated entities and allow us to obtain economic benefits from them. See "Corporate History and Structure—Contractual Arrangements with Our VIEs and Their Respective Shareholders" for more details about these contractual arrangements. In particular, our ability to control the consolidated affiliated entities depends on the powers of attorney, pursuant to which Hode Technology (our WFOE) can vote on all matters requiring shareholder approval in our VIEs. We believe these powers of attorney are legally enforceable but may not be as effective as direct equity ownership.

Although we have been advised by our PRC counsel, Commerce & Finance Law Offices, that each of the contracts among Hode Technology, our VIEs and their shareholders is valid, binding and enforceable under existing PRC laws and regulations, these contractual arrangements may not be as effective in providing control over our VIEs and their subsidiaries as direct ownership. If our VIEs or their shareholders fail to perform their respective obligations under the contractual arrangements, we may incur substantial costs and expend substantial resources to enforce our rights. These contractual arrangements are governed by and interpreted in accordance with PRC law, and disputes arising from these contractual arrangements will be resolved through arbitration in China. However, the legal system in China, particularly as it relates to arbitration proceedings, is not as developed as the legal system in many other jurisdictions, such as the United States. See "—Risks Related to Doing Business in China—Uncertainties in the interpretation and enforcement of PRC laws and regulations could limit the legal protections available to you and us." There are very few precedents and little official guidance as to how contractual arrangements in the context of a variable interest entity should be interpreted or enforced under PRC law. There remain significant uncertainties regarding the ultimate outcome of arbitration should legal action become necessary. These uncertainties could limit our ability to enforce these contractual arrangements. In addition, arbitration awards are final and can only be enforced in PRC courts through arbitration award recognition proceedings, which could cause additional expenses and delays. In the event we are unable to enforce these contractual arrangements or we experience significant delays or other obstacles in the process of enforcing these contractual arrangements, we may not be able to exert effective control over our VIEs and may lose control over the assets owned by our VIEs. As a result, we may be unable to consolidate the financial results of such entities in our consolidated financial statements, our ability to conduct our business may be negatively affected, and our operations could be severely disrupted, which could materially and adversely affect our results of operations and financial condition.

We may lose the ability to use and enjoy assets held by our VIEs and their subsidiaries that are important to our business if our VIEs and their subsidiaries declare bankruptcy or become subject to a dissolution or liquidation proceeding.

Our VIEs hold certain assets that are important to our operations, including the ICP License, License for Online Transmission of Audio-visual Programs and the Online Culture Operating Permit. Under our contractual arrangements, the shareholders of our VIEs may not voluntarily liquidate our VIEs or approve them to sell, transfer, mortgage or dispose of their assets or legal or beneficial

interests exceeding certain threshold in the business in any manner without our prior consent. However, in the event that the shareholders breach this obligation and voluntarily liquidate our VIEs, or our VIEs declare bankruptcy, or all or part of their assets become subject to liens or rights of third-party creditors, we may be unable to continue some or all of our operations, which could materially and adversely affect our business, financial condition and results of operations. Furthermore, if our VIEs or their subsidiaries undergo a voluntary or involuntary liquidation proceeding, their shareholders or unrelated third-party creditors may claim rights to some or all of its assets, hindering our ability to operate our business, which could materially and adversely affect our business, financial condition and results of operations.

Contractual arrangements we have entered into with our VIEs may be subject to scrutiny by the PRC tax authorities. A finding that we owe additional taxes could negatively affect our financial condition and the value of your investment.

Pursuant to applicable PRC laws and regulations, arrangements and transactions among related parties may be subject to audit or challenge by PRC tax authorities. We may be subject to adverse tax consequences if the PRC tax authorities determine that the contractual arrangements among our WFOE, our VIEs and their shareholders are not on an arm's length basis and therefore constitute favorable transfer pricing. As a result, the PRC tax authorities could require that our VIEs adjust their taxable income upward for PRC tax purposes. Such an adjustment could increase our VIEs' tax expenses without reducing the tax expenses of our WFOE, subject our VIEs to late payment fees and other penalties for under-payment of taxes, and result in the loss of any preferential tax treatment our WFOE may have. As a result, our consolidated results of operations may be adversely affected.

If the chops of our PRC subsidiaries, our VIEs and their subsidiaries, are not kept 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 towards third parties even when unaccompanied by a signature. Each legally registered company in China is required to maintain a company chop, which must be registered with the local Public Security Bureau. In addition to this mandatory company chop, companies may have several other chops which can be used for specific purposes. The chops of our PRC subsidiaries, our VIEs and their subsidiaries are generally held securely by personnel designated or approved by us in accordance with our internal control procedures. To the extent those chops are not kept safe, are stolen or are used by unauthorized persons or for unauthorized purposes, the corporate governance of these entities could be severely and adversely compromised and those corporate entities may be bound to abide by the terms of any documents so chopped, even if they were chopped by an individual who lacked the requisite power and authority to do so.

The shareholders of our VIEs may have potential conflicts of interest with us, which may materially and adversely affect our business.

The shareholders of our VIEs include Messrs. Yi Xu, Rui Chen, Xi Cao and Mses. Qian Wei and Ni Li, who are also our shareholders, and, in some cases, our directors or officers. Conflicts of interest may arise between the roles of them as shareholders, directors or officers of our company and as shareholders of our VIEs. For individuals who are also our directors and officers, we rely on them to abide by the laws of the Cayman Islands, which provide that directors and officers owe a fiduciary duty to our company to act in good faith and in the best interest of our company and not to use their positions for personal gain. The shareholders of our VIEs have executed powers of attorney to appoint Hode Technology (our WFOE) or a person designated by Hode Technology to vote on their behalf and exercise voting rights as shareholders of our VIEs. We cannot assure you that when conflicts arise,

these shareholders will act in the best interest of our company or that conflicts will be resolved in our favor. If we cannot resolve any conflicts of interest or disputes between us and these shareholders, we would have to rely on legal proceedings, which may be expensive, time-consuming and disruptive to our operations. There is also substantial uncertainty as to the outcome of any such legal proceedings.

We may rely on dividends paid by our PRC subsidiaries to fund cash and financing requirements. Any limitation on the ability of our PRC subsidiaries to pay dividends to us could have a material adverse effect on our ability to conduct our business and to pay dividends to holders of the ADSs and our ordinary shares.

We are a holding company, and we may rely on dividends to be paid by our PRC subsidiaries for our cash and financing requirements, including the funds necessary to pay dividends and other cash distributions to the holders of the ADSs and our ordinary shares and service any debt we may incur. If our PRC subsidiaries incur debt on their own behalf in the future, the instruments governing the debt may restrict their ability to pay dividends or make other distributions to us.

Under PRC laws and regulations, a wholly foreign-owned enterprise in China, such as Hode Technology, may pay dividends only out of its accumulated profits as determined in accordance with PRC accounting standards and regulations. In addition, a wholly foreign-owned enterprise is required to set aside at least 10% of its after-tax profits each year, after making up previous years' accumulated losses, if any, to fund certain statutory reserve funds, until the aggregate amount of such fund reaches 50% of its registered capital. At the discretion of the board of directors of the wholly foreign-owned enterprise, it may allocate a portion of its after-tax profits based on PRC accounting standards to staff welfare and bonus funds. These reserve funds and staff welfare and bonus funds are not distributable as cash dividends. Any limitation on the ability of our PRC subsidiaries to pay dividends or make other distributions to us could materially and adversely limit our ability to grow, make investments or acquisitions that could be beneficial to our business, pay dividends, or otherwise fund and conduct our business.

Substantial uncertainties exist with respect to the enactment timetable and final content of a draft new PRC Foreign Investment Law and how it may impact the viability of our current corporate structure and operations.

In January 2015, the Ministry of Commerce, or MOFCOM, published a discussion draft of the Foreign Investment Law for public review and comment. Among other things, the draft Foreign Investment Law expands the definition of foreign investment and introduces the principle of "actual control" in determining whether a company should be treated as a foreign invested enterprise, or FIE. It specifically provides that entities established in China (without direct foreign equity ownership) but "controlled" by foreign investors, through contract or trust for example, will be treated as FIEs. Once an entity falls within the definition of FIE, it may be subject to foreign investment "restrictions" or "prohibitions" set forth in a "negative list" to be separately issued by the State Council later. If an FIE proposes to conduct business in an industry subject to foreign investment "restrictions" in the "negative list," the FIE must go through a MOFCOM pre-approval process.

Under the draft Foreign Investment Law, variable interest entities that are controlled via contractual arrangements would be deemed as FIEs if they are ultimately "controlled" by foreign investors, and any of their operations in the industry categories included in the "negative list" without MOFCOM pre-approval may be considered illegal. Conversely, for any companies with a variable interest entity structure engaged in a "restricted" business included in the "negative list," the variable interest entity structure may be deemed legitimate if it is ultimately controlled by PRC nationals. The draft Foreign Investment Law is not specific on what will happen to companies with an existing variable interest entity structure.

The internet content service, internet audio-visual program services and online culture activities that we conduct through our consolidated affiliated entities are subject to foreign investment restrictions set forth in the Guidance Catalogue of Industries for Foreign Investment (2017 Revision) issued by MOFCOM and the National Development and Reform Commission. It is unclear whether the new "negative list" under the draft Foreign Investment Law will be different from the relevant categories in the catalogue. Substantial uncertainties exist with respect to the enactment timetable and final content of the draft Foreign Investment Law. To date, there is no timetable for the enactment of the draft Foreign Investment Law. If the enacted version of the Foreign Investment Law and the final "negative list" mandate further actions to be taken by us, such as a MOFCOM pre-approval process, there is no assurance that we can obtain such pre-approval on a timely basis, or at all.

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

The PRC legal system is based on written statutes and court decisions have limited precedential value. The PRC legal system is evolving rapidly, and the interpretations of many laws, regulations and rules may contain inconsistencies and enforcement of these laws, regulations and rules involves uncertainties.

From time to time, we may have to resort to administrative and court proceedings to enforce our legal rights. However, since PRC judicial and administrative authorities have significant discretion in interpreting and implementing statutory and contractual terms, it may be more difficult to predict the outcome of a judicial or administrative proceeding than in more developed legal systems. Furthermore, the PRC legal system is based, in part, on government policies and internal rules, some of which are not published in a timely manner, or at all, but which may have retroactive effect. As a result, we may not always be aware of any potential violation of these policies and rules. Such unpredictability towards our contractual, property (including intellectual property) and procedural rights could adversely affect our business and impede our ability to continue our operations.

Regulation and censorship of information disseminated over the mobile and internet in China may adversely affect our business and subject us to liability for content posted on our platform.

Internet companies in China are subject to a variety of existing and new rules, regulations, policies, and license and permit requirements on the distribution of information over the mobile and internet. Under these rules and regulations, content service providers are prohibited from posting or displaying over the mobile or internet content that, among others, violates PRC laws and regulations, impairs the national dignity of China or the public interest, is obscene, superstitious, fraudulent or defamatory, or may be deemed by relevant government authorities as "socially destabilizing" or leaking "state secrets" of China. For more information, see "Regulation—Regulations Related to Internet Information Security and Privacy Protection." In connection with enforcing these rules, regulations, policies and requirements, relevant government authorities may suspend services by, or revoke licenses of, any internet or mobile content service provider that is deemed to provide illicit content online or on mobile devices, and such activities may be intensified in connection with any ongoing government campaigns to eliminate prohibited content online. For example, in 2016, the Office of the Anti-Pornography and Illegal Publications Working Group, the State Internet Information Office, the Ministry of Industry and Information Technology, or the MIIT, the Ministry of Culture, or the MOC, and the Ministry of Public Security jointly launched a "Clean Up the Internet 2016" campaign. Based on publicly available information, the campaign aims to eliminate pornographic information and content in the internet information services industry by, among other things, holding liable individuals and corporate entities that facilitate the distribution of pornographic information and content. During the campaign, relevant government authorities shut down 2,500 websites, removed 15,000 links and closed 310,000 accounts.

Certain major public internet companies voluntarily initiated self-investigations to filter and remove content from their websites and cloud servers. In 2017, the regulatory authorities jointly initiated a "Clean Up the Internet 2017" campaign and, based on the publicly available information on November 7, 2017, 1,655 websites have been shut down during the campaign.

We endeavor to eliminate illicit content from our platform. We have made substantial investments in resources to monitor content that users post on our platform and the way in which our users engage with each other through our platform. In the past, we have terminated certain user accounts in order to eliminate spam, fictitious accounts and indecent content from our platform. We use a variety of methods to ensure our platform remains a healthy and positive experience for our users, including a designated content management team and our own data analytics software. Although we employ these methods to filter our users and content posted by our users, we cannot be sure that our internal content control efforts will be sufficient to remove all content that may be viewed as indecent or otherwise non-compliant with PRC law and regulations. Government standards and interpretations as to what constitutes illicit online content or behavior are subject to interpretation and may change.

We have paid fines in connection with content posted on our platform, and government standards and interpretations may change in a manner that could render our current monitoring efforts insufficient. The PRC government has wide discretion in regulating online activities and, irrespective of our efforts to control the content on our platform, government campaigns and other actions to reduce illicit content and activities could subject us to negative 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, including closure of one or more parts of or our entire business. Further, our senior management could be held criminally liable if we are deemed to be profiting from illicit content on our platform. Although our operations have not been materially adversely affected by government campaigns or any other regulatory actions in the past, we cannot assure you that our business and operations will be immune from government actions or sanctions in the future. If government actions or sanctions are brought against us, or if there are widespread rumors that government actions or sanctions have been brought against us, our reputation could be harmed, we may lose users and other customers, our revenues and results of operation may be materially and adversely affected and the value of our ADSs could be dramatically reduced.

If we fail to obtain and maintain the requisite licenses and approvals required under the complex regulatory environment applicable to our businesses in China, or if we are required to take compliance actions that are time-consuming or costly, our business, financial condition and results of operations may be materially and adversely affected.

The internet and mobile industries in China are highly regulated. Our consolidated affiliated entities are required to obtain and maintain applicable licenses and approvals from different regulatory authorities in order to provide their current services. Under the current PRC regulatory scheme, a number of regulatory agencies, including but not limited to the State Administration of Press, Publication, Radio, Film and Television of China, or the SAPPRFT, the MOC, the MIIT, the State Council Information Office, and the State Internet Information Office, jointly regulate all major aspects of the internet industry, including the mobile internet and mobile games businesses. Operators must obtain various government approvals and licenses for relevant mobile business.

We have obtained ICP licenses for the provision of internet information services, license for online transmission of audio-visual programs for the provision of internet audio-visual program services, and Online Culture Operating Licenses for operation of online games, and have submitted an application to update our license for online transmission of audio-visual programs to cover the transmission to mobile devices. These licenses are essential to the operation of our business and are generally subject to regular government review or renewal. However, we cannot assure you that we can successfully renew these licenses in a timely manner or that these licenses are sufficient to conduct all of our present or future business.

Under regulations issued by the SAPPRFT, the publication of each online game requires approval from the SAPPRFT. As of the date of this prospectus, we have obtained approvals from the SAPPRFT for all of the domestic online games and two imported online games exclusively operated by us. We will apply with the SAPPRFT for the approvals of our future games. We also require third parties to obtain requisite approvals from the SAPPRFT, and make filings with the MOC, for the online games we jointly operate with such third parties. However, we cannot assure you that we or such third parties can obtain the SAPPRFT's approvals or complete the filing with the MOC for all games in a timely manner or at all. In addition, as the provision of online games is deemed to be an internet publication activity, an online game operator must obtain an Internet Publication Service License in order to directly make those games publicly available in China. Although it is not specifically authorized by the SAPPRFT, an online game operator is generally able to publish its games through third-party licensed electronic publishing entities and register the games with the SAPPRFT as electronic publications. Shanghai Hode is planning to apply for the Internet Publishing Service License for our operation of online games. However, there is no assurance that we will be granted such license. If we fail to complete, obtain or maintain any of the required licenses or approvals or make the necessary filings, we may be subject to various penalties, such as confiscation of the net revenues that were generated through online games, the imposition of fines, the revocation of our business and operating licenses and the discontinuation or restriction of our operations of online games.

Considerable uncertainties exist regarding the interpretation and implementation of existing and future laws and regulations governing our business activities. For example, in 2009, the SAPPRFT, together with other authorities issued a notice known as Circular 13, which expressly prohibits foreign investors from participating in online game operating businesses in China via wholly foreign-owned entities, China-foreign equity joint ventures or cooperative joint ventures or from controlling over or participating in the operation of domestic online game businesses through indirect means, such as other joint venture companies or contractual or technical arrangements. While Circular 13 is applicable to us and our online game business on an overall basis, the SAPPRFT has not issued any interpretation of Circular 13, and we are not aware of any online game companies which use the same or similar variable interest entity contractual arrangements as those we use having been challenged by the SAPPRFT. In addition, under the Administrative Regulations on the Introduction and Broadcasting of Foreign Television Programs, the introduction or broadcasting of foreign animation in China is subject to approval of the SAPPRFT or its authorized entities. However, approval or filing procedures are not explicitly required in practice by the SAPPRFT for the broadcasting and distribution of foreign animation on the internet only. We have not obtained any approval from, or completed any filing with, the SAPPRFT or competent local counterparts for broadcasting and distribution of foreign animation on our platform. We could be found in violation of any future laws and regulations or of the laws and regulations currently in effect due to changes in the relevant authorities' interpretation of these laws and regulations. If we fail to complete, obtain or maintain any of the required licenses or approvals or make the necessary filings, we may be subject to various penalties, such as confiscation of the net revenues that were generated through the unlicensed internet or mobile activities, the imposition of fines and the discontinuation or restriction of our operations. Any such penalties or changes in policies, regulations or enforcement by government authorities, may disrupt our operations and materially and adversely affect our business, financial condition and results of operations.

Adverse changes in economic and political policies of the PRC government could have a material and adverse effect on overall economic growth in China, which could materially and adversely affect our business.

Our revenues are substantially sourced from China. Accordingly, our results of operations, financial condition and prospects are influenced by economic, political and legal developments in China. Economic reforms begun in the late 1970s have resulted in significant economic growth. However, any economic 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 with respect to the amount of government involvement, level of development, growth rate, control of foreign exchange and allocation of resources. While the PRC economy has experienced significant growth in the past 30 years, growth has been uneven across different regions and among different economic sectors.

The PRC government exercises significant control over China's economic growth through strategically allocating resources, controlling the payment of foreign currency-denominated obligations, setting monetary policy and providing preferential treatment to particular industries or companies. Although the PRC economy has grown significantly in the past decade, that growth may not continue, as evidenced by the slowing of the growth of the PRC economy since 2012. Any adverse changes in economic conditions in China, in the policies of the PRC government or in the laws and regulations in China could have a material adverse effect on the overall economic growth of China. Such developments could adversely affect our business and operating results, lead to reduction in demand for our services and adversely affect our competitive position.

Currently there is no law or regulation specifically governing virtual asset property rights and therefore it is not clear what liabilities, if any, online game operators may have for virtual assets.

While playing online games or participating on platform activities, our users acquire and accumulate some virtual assets, such as special equipment and other accessories. Such virtual assets can be important to online game players and have monetary value and, in some cases, are sold for actual money. In practice, virtual assets can be lost for various reasons, often through unauthorized use of the game account of one user by other users and occasionally through data loss caused by a delay of network service, a network crash or hacking activities. Currently, there is no PRC law or regulation specifically governing virtual asset property rights. As a result, there is uncertainty as to who the legal owner of virtual assets is, whether and how the ownership of virtual assets is protected by law, and whether an operator of online games such as us would have any liability to game players or other interested parties (whether in contract, tort or otherwise) for loss of such virtual assets. Based on recent PRC court judgments, courts have typically held online game operators liable for losses of virtual assets by game players, and ordered online game operators to return the lost virtual items to game players or pay damages and losses. In case of a loss of virtual assets, we may be sued by our game players or users and held liable for damages, which may negatively affect our reputation and business, financial condition and results of operations.

Restrictions on virtual currency may adversely affect our online game revenues.

Our revenues from mobile games are collected through the online sale of in-game currencies, which are considered to be the "virtual currency" as such term is defined in the Notice on Strengthening the Administration of Online Game Virtual Currency, which was jointly issued by the MOC and MOFCOM in 2009. PRC laws and regulations, including this notice, have provided various restrictions on virtual currency and imposed various requirements and obligations on online game operators with respect to the virtual currency used in their games, including that (i) any entity engaged in the services relating to the issuance or trading of virtual currencies for online gaming shall comply with the conditions relevant to the establishment of an internet culture entity for business purpose and file an application with the provincial administrative department of culture at its locality for preliminary examination and then with the MOC for approval; (ii) the total amount of virtual currency issued by online game operators and the amount purchased by individual users in China is subject to limits, and online game operators are required to report the total amount of their issued virtual currency on a quarterly basis and are prohibited from issuing disproportionate amounts of virtual currency in order to generate revenues; (iii) virtual currency may only be provided to users in exchange for payment in RMB and may only be used to pay for virtual goods and services of the issuer of the currency, and online game operators are required to keep transaction data records for no less than 180 days;

(iv) online game operators are prohibited from providing lucky draws or lotteries that are conducted on the condition that participants contribute cash or virtual currency in exchange for game props or virtual currencies; (v) online game operators are prohibited from providing virtual currency trading services to minors; and (vi) companies involved with virtual currency in China must be either issuers or trading platforms, and may not operate simultaneously both as issuers and as trading platforms. The MOC issued the Notice of Ministry of Culture on Regulating Online Game Operation Strengthening Interim and Ex-post Supervision, effective on May 1, 2017, which stipulates that online game operators may not allow online game virtual currency to be exchanged for real currency or physical items, except that, when online game operators cease offering their online game products and services to users, the operators may repay the users with real currency or other actual physical or intangible assets for unused virtual currency. We must tailor our business model carefully, including designing and operating our databases to maintain user information for the minimum required period, in order to comply with the current PRC laws and regulations, including the foregoing notices, in a manner that in many cases can be expected to result in an adverse impact on our online game revenues.

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

Under PRC advertising laws and regulations, we are obligated to monitor the advertising content shown on our platform to ensure that such content is true and accurate and in compliance with applicable laws and regulations. In addition, where a special government review is required for specific types of advertisements prior to internet posting, such as advertisements relating to pharmaceuticals, medical instruments, agrochemicals and veterinary pharmaceuticals, we are obligated to confirm that such review has been performed and approval has been obtained. Violation of these laws and regulations may subject us to penalties, including imposition of fines, confiscation of our advertising income, orders to cease dissemination of the advertisements and orders to publish an announcement correcting the misleading information. In circumstances involving serious violations by us, PRC governmental authorities may force us to terminate our advertising operations or revoke our licenses.

While we have made significant efforts to ensure that the advertisements shown on our platform are in full compliance with applicable PRC laws and regulations, we cannot assure you that all the content contained in such advertisements is true and accurate as required by the advertising laws and regulations, especially given the uncertainty in the interpretation of these PRC laws and regulations. If we are found to be in violation of applicable PRC advertising laws and regulations, we may be subject to penalties and our reputation may be harmed, which may have a material and adverse effect on our business, financial condition, results of operations and prospects.

Under the PRC Enterprise Income Tax Law, we may be classified as a PRC resident enterprise, which could result in unfavorable tax consequences to us and our shareholders and have a material adverse effect on our results of operations and the value of your investment.

Under the PRC Enterprise Income Tax Law, effective 2008, an enterprise established outside China with "de facto management bodies" within China is considered a "resident enterprise" for PRC enterprise income tax purposes and is generally subject to a uniform 25% enterprise income tax rate on its worldwide income. In 2009, the State Administration of Taxation, or the SAT, issued the Notice Regarding the Determination of PRC-Controlled Overseas Incorporated Enterprises as PRC Tax Resident Enterprise on the Basis of De Facto Management Bodies, or SAT Circular 82, which provides certain specific criteria for determining whether the "de facto management body" of a PRC-controlled enterprise that is incorporated offshore is located in China. Further to SAT Circular 82, the SAT issued the Administrative Measures for Enterprise Income Tax of PRC-Controlled Offshore Incorporated Resident Enterprises (Trial), or SAT Bulletin 45, effective 2011, to provide more guidance on the implementation of SAT Circular 82. SAT Bulletin 45 clarified certain issues in the areas of resident status determination, post-determination administration and competent tax authorities' procedures.

According to SAT Circular 82, an offshore incorporated enterprise controlled by a PRC enterprise or a PRC enterprise group will be considered as a PRC tax resident enterprise by virtue of having its "de facto management body" in China and will be subject to PRC enterprise income tax on its worldwide income only if all of the following conditions are met: (a) the senior management and core management departments in charge of its daily operations function have their presence mainly in China; (b) its financial and human resources decisions are subject to determination or approval by persons or bodies in China; (c) its major assets, accounting books, company seals, and minutes and files of its board and shareholders' meetings are located or kept in China; and (d) more than half of the enterprise's directors or senior management with voting rights habitually reside in China. SAT Bulletin 45 specifies that when provided with a copy of a PRC tax resident determination certificate from a resident PRC controlled offshore incorporated enterprise, the payer should not withhold 10% income tax when paying the PRC-sourced dividends, interest and royalties to the PRC controlled offshore incorporated enterprise.

Although SAT Circular 82 and SAT Bulletin 45 only apply to offshore incorporated enterprises controlled by PRC enterprises or PRC enterprise groups and not those controlled by PRC individuals or foreigners, the determination criteria set forth therein may reflect the SAT's general position on how the term "de facto management body" could be applied in determining the tax resident status of offshore enterprises, regardless of whether they are controlled by PRC enterprises, individuals or foreigners.

In addition, the SAT issued the Announcement of the State Administration of Taxation on Issues concerning the Determination of Resident Enterprises Based on the Standards of Actual Management Institutions in January 2014 to provide more guidance on the implementation of SAT Circular 82. This bulletin further provides that, among other things, an entity that is classified as a "resident enterprise" in accordance with the circular shall file the application for classifying its status of residential enterprise with the local tax authorities where its main domestic investors are registered. From the year in which the entity is determined to be a "resident enterprise," any dividend, profit and other equity investment gain shall be taxed in accordance with the enterprise income tax law and its implementing rules.

If the PRC tax authorities determine that we or any of our non-PRC subsidiaries is a PRC resident enterprise for PRC enterprise income tax purposes, then we or any such non-PRC subsidiary could be subject to PRC tax at a rate of 25% on its world-wide income, which could materially affect our financial performance. In addition, we will also be subject to PRC enterprise income tax reporting obligations.

If the PRC tax authorities determine that our company is a PRC resident enterprise for PRC enterprise income tax purposes, gains realized on the sale or other disposition of ADSs or ordinary shares may be subject to PRC tax, at a rate of 10% in the case of non-PRC enterprises or 20% in the case of non-PRC individuals (in each case, subject to the provisions of any applicable tax treaty), if such gains are deemed to be from PRC sources. Any such tax may reduce the returns on your investment in the ADSs.

There are significant uncertainties under the PRC Enterprise Income Tax Law relating to the withholding tax liabilities of our PRC subsidiaries, and dividends payable by our PRC subsidiaries to our offshore subsidiaries may not qualify to enjoy certain treaty benefits.

Under the PRC Enterprise Income Tax Law and its implementation rules, the profits of a foreign-invested enterprise generated through operations, which are distributed to its immediate holding company outside China, will be subject to a withholding tax rate of 10%. Pursuant to a special arrangement between Hong Kong and China, such rate may be reduced to 5% if a Hong Kong resident enterprise owns more than 25% of the equity interest in the PRC company. Our current PRC subsidiaries are wholly owned by our Hong Kong subsidiary, Hode HK. Accordingly, Hode HK may

qualify for a 5% tax rate in respect of distributions from its PRC subsidiaries. Under the Notice of the State Administration of Taxation on Issues regarding the Administration of the Dividend Provision in Tax Treaties promulgated in 2009, the taxpayer needs to satisfy certain conditions to enjoy the benefits under a tax treaty. These conditions include: (i) the taxpayer must be the beneficial owner of the relevant dividends, and (ii) the corporate shareholder to receive dividends from the PRC subsidiaries must have met the direct ownership thresholds during the 12 consecutive months preceding the receipt of the dividends. Further, the SAT promulgated the Notice on How to Understand and Recognize the "Beneficial Owner" in Tax Treaties in 2009, which limits the "beneficial owner" to individuals, enterprises or other organizations normally engaged in substantive operations, and sets forth certain detailed factors in determining "beneficial owner" status.

Entitlement to a lower tax rate on dividends according to tax treaties or arrangements between the PRC central government and governments of other countries or regions is subject to the Administrative Measures for Non-Resident Taxpayers to Enjoy Treatments under Tax Treaties, which provides that non-resident enterprises are not required to obtain pre-approval from the relevant tax authority in order to enjoy the reduced withholding tax. Instead, non-resident enterprises and their withholding agents may, by self-assessment and on confirmation that the prescribed criteria to enjoy the tax treaty benefits are met, directly apply the reduced withholding tax rate, and file necessary forms and supporting documents when performing tax filings, which will be subject to post-tax filing examinations by the relevant tax authorities. As a result, we cannot assure you that we will be entitled to any preferential withholding tax rate under tax treaties for dividends received from our PRC subsidiaries.

We face uncertainty with respect to indirect transfer of equity interests in PRC resident enterprises by their non-PRC holding companies.

We face uncertainties regarding the reporting on and consequences of previous private equity financing transactions involving the transfer and exchange of shares in our company by non-resident investors.

In February 2015, the SAT issued the Bulletin on Issues of Enterprise Income Tax on Indirect Transfers of Assets by Non-PRC Resident Enterprises, or SAT Bulletin 7, as amended in 2017. Pursuant to this bulletin, an "indirect transfer" of assets, including equity interests in a PRC resident enterprise, by non-PRC resident enterprises may be re-characterized and treated as a direct transfer of PRC taxable assets, if such arrangement does not have a reasonable commercial purpose and was established for the purpose of avoiding payment of PRC enterprise income tax. As a result, gains derived from such indirect transfer may be subject to PRC enterprise income tax. According to SAT Bulletin 7, "PRC taxable assets" include assets attributed to an establishment in China, immovable properties located in China, and equity investments in PRC resident enterprises, in respect of which gains from their transfer by a direct holder, being a non-PRC resident enterprise, would be subject to PRC enterprise income taxes. When determining whether there is a "reasonable commercial purpose" of the transaction arrangement, features to be taken into consideration include: whether the main value of the equity interest of the relevant offshore enterprise derives from PRC taxable assets; whether the assets of the relevant offshore enterprise mainly consist of direct or indirect investment in China or if its income mainly derives from China; whether the offshore enterprise and its subsidiaries directly or indirectly holding PRC taxable assets have real commercial nature which is evidenced by their actual function and risk exposure; the duration of existence of the business model and organizational structure; the replicability of the transaction by direct transfer of PRC taxable assets; and the tax situation of such indirect transfer and applicable tax treaties or similar arrangements. In respect of an indirect offshore transfer of assets of a PRC establishment, the resulting gain is to be included with the enterprise income tax filing of the PRC establishment or place of business being transferred, and would consequently be subject to PRC enterprise income tax at a rate of 25%. Where the underlying transfer relates to the immovable properties located in China or to equity investments in a PRC resident

enterprise, which is not related to a PRC establishment or place of business of a non-resident enterprise, a PRC enterprise income tax of 10% would apply, subject to available preferential tax treatment under applicable tax treaties or similar arrangements, and the party who is obligated to make the transfer payments has the withholding obligation. Where the payor fails to withhold any or sufficient tax, the transferor is required to declare and pay such tax to the tax authority by itself within the statutory time limit. Late payment of applicable tax will subject the transferor to default interest. SAT Bulletin 7 does not apply to transactions of sale of shares by investors through a public stock exchange where such shares were acquired from a transaction through a public stock exchange.

There is uncertainty as to the application of SAT Bulletin 7. We face uncertainties as to the reporting and other implications of certain past and future transactions where PRC taxable assets are involved, such as offshore restructuring, sale of the shares in our offshore subsidiaries or investments. Our company may be subject to filing obligations or taxed if our company is transferor in such transactions, and may be subject to withholding obligations if our company is transferee in such transactions under SAT Bulletin 7. For transfer of shares in our company by investors that are non-PRC resident enterprises, our PRC subsidiaries may be requested to assist in the filing under SAT Bulletin 7. As a result, we may be required to expend valuable resources to comply with SAT Bulletin 7 or to request the relevant transferors from whom we purchase taxable assets to comply with these circulars, or to establish that our company should not be taxed under these circulars, which may have a material adverse effect on our financial condition and results of operations.

China's M&A Rules and certain other PRC regulations establish complex procedures for some acquisitions of PRC companies by foreign investors, which could make it more difficult for us to pursue growth through acquisitions in China.

The Regulations on Mergers and Acquisitions of Domestic Enterprises by Foreign Investors, or the M&A Rules, and other recently adopted regulations and rules concerning mergers and acquisitions established additional procedures and requirements that could make merger and acquisition activities by foreign investors more time consuming and complex. For example, the M&A Rules require that MOFCOM be notified in advance of any change-of-control transaction in which a foreign investor takes control of a PRC domestic enterprise, if (i) any important industry is concerned, (ii) such transaction involves factors that impact or may impact national economic security, or (iii) such transaction will lead to a change in control of a domestic enterprise which holds a famous trademark or PRC time-honored brand. Moreover, the Anti-Monopoly Law promulgated by the Standing Committee of the National People's Congress effective 2008 requires that transactions which are deemed concentrations and involve parties with specified turnover thresholds (i.e., during the previous fiscal year, (i) the total global turnover of all operators participating in the transaction exceeds RMB10 billion and at least two of these operators each had a turnover of more than RMB400 million within China, or (ii) the total turnover within China of all the operators participating in the concentration exceeded RMB2 billion, and at least two of these operators each had a turnover of more than RMB400 million within China) must be cleared by MOFCOM before they can be completed. In addition, in 2011, the General Office of the State Council promulgated a Notice on Establishing the Security Review System for Mergers and Acquisitions of Domestic Enterprises by Foreign Investors, also known as Circular 6, which officially established a security review system for mergers and acquisitions of domestic enterprises by foreign investors. Further, MOFCOM promulgated the Regulations on Implementation of Security Review System for the Merger and Acquisition of Domestic Enterprises by Foreign Investors, effective 2011, to implement Circular 6. Under Circular 6, a security review is required for mergers and acquisitions by foreign investors having "national defense and security" concerns and mergers and acquisitions by which foreign investors may acquire the "de facto control" of domestic enterprises with "national security" concerns. Under the foregoing MOFCOM regulations, MOFCOM will focus on the substance and actual impact of the transaction when deciding whether a specific merger or acquisition is subject to security review. If MOFCOM decides that a specific merger or acquisition is subject to a security

review, it will submit it to the Inter-Ministerial Panel, an authority established under Circular 6 led by the National Development and Reform Commission, and MOFCOM under the leadership of the State Council, to carry out security review. The regulations prohibit foreign investors from bypassing the security review by structuring transactions through trusts, indirect investments, leases, loans, control through contractual arrangements or offshore transactions. There is no explicit provision or official interpretation stating that the merging or acquisition of a company engaged in the internet content or mobile games business requires security review, and there is no requirement that acquisitions completed prior to the promulgation of the Security Review Circular are subject to MOFCOM review.

In the future, we may grow our business by acquiring complementary businesses. Complying with the requirements of the above-mentioned regulations and other relevant rules to complete such transactions could be time consuming, and any required approval processes, including obtaining approval from MOFCOM or its local counterparts may delay or inhibit our ability to complete such transactions. It is unclear whether our business would be deemed to be in an industry that raises "national defense and security" or "national security" concerns. However, MOFCOM or other government agencies may publish explanations in the future determining that our business is in an industry subject to the security review, in which case our future acquisitions in China, including those by way of entering into contractual control arrangements with target entities, may be closely scrutinized or prohibited.

PRC regulations relating to offshore investment activities by PRC residents may limit our PRC subsidiary's ability to increase their registered capital or distribute profits to us or otherwise expose us to liability and penalties under PRC law.

The State Administration of Foreign Exchange, or SAFE, promulgated the Circular on Relevant Issues Relating to Domestic Resident's Investment and Financing and Roundtrip Investment through Special Purpose Vehicles, or SAFE Circular 37, in July 2014 that requires PRC residents or entities to register with SAFE or its local branch in connection with their establishment or control of an offshore entity established for the purpose of overseas investment or financing. In addition, such PRC residents or entities must update their SAFE registrations when the offshore special purpose vehicle undergoes material events relating to any change of basic information (including change of such PRC citizens or residents, name and operation term), increases or decreases in investment amount, transfers or exchanges of shares, or mergers or divisions. According to the Notice on Further Simplifying and Improving Policies for the Foreign Exchange Administration of Direct Investment released in February 2015 by SAFE, local banks will examine and handle foreign exchange registration for overseas direct investment, including the initial foreign exchange registration and amendment registration, under SAFE Circular 37 from June 2015.

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

Messrs. Yi Xu, Rui Chen, Xi Cao and Mses. Qian Wei and Ni Li have completed initial SAFE registration in connection with our financings and will update their registration filings with SAFE under SAFE Circular 37 when any changes should be registered under SAFE Circular 37. However, we may not at all times be fully aware or informed of the identities of all our shareholders or beneficial owners that are required to make or update such registrations, and we cannot compel our beneficial owners to comply with SAFE registration requirements. As a result, we cannot assure you that all of our shareholders or beneficial owners who are PRC residents or entities have complied with, and will in the future make or obtain any applicable registrations or approvals required by, SAFE regulations. Failure

by such shareholders or beneficial owners to comply with SAFE regulations or failure by us to amend the foreign exchange registrations of our PRC subsidiaries, could subject us to fines or legal sanctions, restrict our overseas or cross-border investment activities, limit our subsidiaries' ability to make distributions or pay dividends or affect our ownership structure, which could adversely affect our business and prospects.

Failure to comply with PRC regulations regarding the registration requirements for employee stock ownership plans or share option plans may subject the PRC plan participants or us to fines and other legal or administrative sanctions.

Pursuant to SAFE Circular 37, PRC residents who participate in share incentive plans in overseas non-publicly-listed companies due to their position as director, senior management or employees of the PRC subsidiaries of the overseas companies may submit applications to SAFE or its local branches for the foreign exchange registration with respect to offshore special purpose companies. Our directors, executive officers and other employees who are PRC residents and who have been granted options may follow SAFE Circular 37 to apply for the foreign exchange registration before our company becomes an overseas listed company. In 2012, SAFE promulgated the Notices on Issues Concerning the Foreign Exchange Administration for Domestic Individuals Participating in Stock Incentive Plans of Overseas Publicly-Listed Companies. Under the notices and other relevant rules and regulations, PRC residents who participate in stock incentive plan in an overseas publicly-listed company are required to register with SAFE or its local branches and complete certain other procedures. Participants of a stock incentive plan who are PRC residents must retain a qualified PRC agent, which could be a PRC subsidiary of such overseas publicly listed company or another qualified institution selected by such PRC subsidiary, to conduct the SAFE registration and other procedures with respect to the stock incentive plan on behalf of its participants. Such participants must also retain an overseas entrusted institution to handle matters in connection with their exercise of stock options, the purchase and sale of corresponding shares or interests and fund transfers. In addition, the PRC agent is required to amend the SAFE registration with respect to the stock incentive plan if there is any material change to the stock incentive plan, the PRC agent or the overseas entrusted institution or other material changes. We and our PRC employees who have been granted stock options will be subject to these regulations upon the completion of this offering. Failure of our PRC stock option holders to complete their SAFE registrations may subject these PRC residents to fines and legal sanctions and may also limit our ability to contribute additional capital into our PRC subsidiary, limit our PRC subsidiary's ability to distribute dividends to us, or otherwise materially adversely affect our business.

PRC regulation of loans to, and direct investment in, PRC entities by offshore holding companies and governmental control of currency conversion may restrict or prevent us from using the proceeds of our initial public offering to make loans to our PRC subsidiaries and our VIEs and their subsidiaries, or to make additional capital contributions to our PRC subsidiaries.

We are an offshore holding company conducting our operations in China through our PRC subsidiaries, VIEs and their subsidiaries. We may make loans to our PRC subsidiaries, VIEs and their subsidiaries, or we may make additional capital contributions to our PRC subsidiaries, or we may establish new PRC subsidiaries and make capital contributions to these new PRC subsidiaries, or we may acquire offshore entities with business operations in China in an offshore transaction.

Most of these ways are subject to PRC regulations and approvals. For example, loans by us to our wholly owned PRC subsidiaries to finance their activities cannot exceed statutory limits and must be registered with the local counterpart of SAFE. If we decide to finance our wholly owned PRC subsidiaries by means of capital contributions, these capital contributions are subject to the requirement of making necessary filings in the Foreign Investment Comprehensive Management Information System and registration with other governmental authorities in China. Due to the restrictions imposed on loans

in foreign currencies extended to any PRC domestic companies, we are not likely to make such loans to our consolidated affiliated entities, which are PRC domestic company. Further, we are not likely to finance the activities of our consolidated affiliated entities by means of capital contributions due to regulatory restrictions relating to foreign investment in PRC domestic enterprises engaged in internet information services, online games, online audio-visual program services and related businesses.

SAFE promulgated the Notice of the State Administration of Foreign Exchange on Reforming the Administration of Foreign Exchange Settlement of Capital of Foreign-invested Enterprises, or SAFE Circular 19, effective June 2015, in replacement of the Circular on the Relevant Operating Issues Concerning the Improvement of the Administration of the Payment and Settlement of Foreign Currency Capital of Foreign-Invested Enterprises, the Notice from the State Administration of Foreign Exchange on Relevant Issues Concerning Strengthening the Administration of Foreign Exchange Businesses, and the Circular on Further Clarification and Regulation of the Issues Concerning the Administration of Certain Capital Account Foreign Exchange Businesses. According to SAFE Circular 19, the flow and use of the RMB capital converted from foreign currency-denominated registered capital of a foreign-invested company is regulated such that RMB capital may not be used for the issuance of RMB entrusted loans, the repayment of inter-enterprise loans or the repayment of banks loans that have been transferred to a third party. Although SAFE Circular 19 allows RMB capital converted from foreign currency-denominated registered capital of a foreign-invested enterprise to be used for equity investments within China, it also reiterates the principle that RMB converted from the foreign currency-denominated capital of a foreign-invested company may not be directly or indirectly used for purposes beyond its business scope. Thus, it is unclear whether SAFE will permit such capital to be used for equity investments in China in actual practice. SAFE promulgated the Notice of the State Administration of Foreign Exchange on Reforming and Standardizing the Foreign Exchange Settlement Management Policy of Capital Account, or SAFE Circular 16, effective on June 9, 2016, which reiterates some of the rules set forth in SAFE Circular 19, but changes the prohibition against using RMB capital converted from foreign currency-denominated registered capital of a foreign-invested company to issue RMB entrusted loans to a prohibition against using such capital to issue loans to non-associated enterprises. 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 any foreign currency we hold, including the net proceeds from this offering, to our PRC subsidiaries, which may adversely affect our liquidity and our ability to fund and expand our business in China.

In light of the various requirements imposed by PRC regulations on loans to and direct investment in PRC entities by offshore holding companies, we cannot assure you that we will be able to complete the necessary government registrations or obtain the necessary government approvals on a timely basis, if at all, with respect to future loans by us to our PRC subsidiary or with respect to future capital contributions by us to our PRC subsidiary. If we fail to complete such registrations or obtain such approvals, our ability to use the proceeds we received from our initial public offering and to capitalize or otherwise fund our PRC operations may be negatively affected, which could materially and adversely affect our liquidity and our ability to fund and expand our business.

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

The value of the RMB against the U.S. dollar and other currencies is affected by changes in China's political and economic conditions and China's foreign exchange policies, among other things. In 2005, the PRC government changed its decades-old policy of pegging the value of the RMB to the U.S. dollar, and the RMB appreciated more than 20% against the U.S. dollar over the following three years. Between July 2008 and June 2010, this appreciation halted and the exchange rate between Renminbi and the U.S. dollar remained within a narrow band. Since June 2010, Renminbi has fluctuated against the U.S. dollar, at times significantly and unpredictably. With the development of the

foreign exchange market and progress towards interest rate liberalization and Renminbi internationalization, the PRC government may in the future announce further changes to the exchange rate system and we cannot assure you that Renminbi will not appreciate or depreciate significantly in value against the U.S. dollar in the future. It is difficult to predict how market forces or PRC or U.S. government policy may impact the exchange rate between Renminbi and the U.S. dollar in the future.

Substantially all of our revenues and costs are denominated in RMB, and substantially all of our financial assets are also denominated in RMB. Any significant depreciation of the RMB may materially adversely affect the value of, and any dividends payable on, our ADSs in U.S. dollars. To the extent that we need to convert U.S. dollars we receive from this offering into RMB for our operations, appreciation of the RMB against U.S. dollar would have 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 paying dividends on our ordinary shares or ADSs or for other business purposes, appreciation of the U.S. dollar against the RMB would have an adverse effect on the U.S. dollar amount available to us.

Governmental control of currency conversion may limit our ability to utilize our revenues effectively and affect the value of your investment.

The PRC government imposes controls on the convertibility of the Renminbi into foreign currencies and, in certain cases, the remittance of currency out of China. We receive substantially all of our revenues in Renminbi. Under our current corporate structure, our Cayman Islands holding company primarily relies on dividend payments from our PRC subsidiaries to fund any cash and financing requirements we may have. Under existing PRC foreign exchange regulations, payments of current account items, including profit distributions, interest payments and trade and service-related foreign exchange transactions, can be made in foreign currencies without prior approval of SAFE by complying with certain procedural requirements. Specifically, under the existing exchange restrictions, without prior approval of SAFE, cash generated from the operations of our PRC subsidiaries in China may be used to pay dividends to our company. However, approval from or registration with appropriate government authorities is required where Renminbi is to be converted into foreign currency and remitted out of China to pay capital expenses such as the repayment of loans denominated in foreign currencies. As a result, we need to obtain SAFE approval to use cash generated from the operations of our PRC subsidiaries and VIEs to pay off their respective debt in a currency other than Renminbi owed to entities outside China, or to make other capital expenditure payments outside China in a currency other than Renminbi.

In light of the flood of capital outflows of China in 2016 due to the weakening RMB, the PRC government has imposed more restrictive foreign exchange policies and stepped up scrutiny of major outbound capital movement including overseas direct investment. More restrictions and substantial vetting process are put in place by SAFE to regulate cross-border transactions falling under the capital account. If any of our shareholders regulated by such policies fails to satisfy the applicable overseas direct investment filing or approval requirement timely or at all, it may be subject to penalties from the relevant PRC authorities. The PRC government may at its discretion further restrict access in the future to foreign currencies for current account transactions. If the foreign exchange control system prevents us from obtaining sufficient foreign currencies to satisfy our foreign currency demands, we may not be able to pay dividends in foreign currencies to our shareholders, including holders of our ADSs.

The audit report included in this prospectus is prepared by an auditor who is not inspected by the PCAOB and, as such, you are deprived of the benefits of such inspection.

Our independent registered public accounting firm that issues the audit reports included in our prospectus filed with the US Securities and Exchange Commission, as auditors of companies that are traded publicly in the United States and a firm registered with the PCAOB, is required by U.S. laws to undergo regular inspections by the PCAOB to assess its compliance with U.S. laws and professional standards. Because our auditors are located in China, a jurisdiction where the PCAOB is currently unable to conduct inspections without the approval of the PRC authorities, our auditors are not currently inspected by the PCAOB.

Inspections of other firms that the PCAOB has conducted outside China have identified deficiencies in those firms' audit procedures and quality control procedures, which may be addressed as part of the inspection process to improve future audit quality. This lack of PCAOB inspections in China prevents the PCAOB from regularly evaluating our auditor's audits and its quality control procedures. As a result, investors may be deprived of the benefits of PCAOB inspections.

The inability of the PCAOB to conduct inspections of auditors in China makes it more difficult to evaluate the effectiveness of our auditor's audit procedures or quality control procedures as compared to auditors outside of China that are subject to PCAOB inspections. Investors may lose confidence in our reported financial information and procedures and the quality of our financial statements.

Proceedings instituted by the SEC against the "big four" PRC-based accounting firms, including our independent registered public accounting firm, could result in financial statements being determined to not be in compliance with the requirements of the Exchange Act.

In late 2012, the SEC commenced administrative proceedings under Rule 102(e) of its Rules of Practice and also under the Sarbanes-Oxley Act against the Chinese affiliates of the "big four" accounting firms (including our auditors). The Rule 102(e) proceedings initiated by the SEC relate to these firms' inability to produce documents, including audit work papers, in response to the request of the SEC pursuant to Section 106 of the Sarbanes-Oxley Act, as the auditors located in the PRC are not in a position lawfully to produce documents directly to the SEC because of restrictions under PRC law and specific directives issued by the China Securities Regulatory Commission, or the CSRC. The issues raised by the proceedings are not specific to our auditors or to us, but affect equally all audit firms based in China and all China-based businesses with securities listed in the United States.

In January 2014, the administrative judge reached an Initial Decision that the Chinese affiliates of "big four" accounting firms should be barred from practicing before the SEC for six months. Thereafter, the accounting firms filed a Petition for Review of the Initial Decision, prompting the SEC Commissioners to review the Initial Decision, determine whether there had been any violation and, if so, determine the appropriate remedy to be placed on these audit firms.

In February 2015, the Chinese affiliates of the "big four" accounting firms (including our auditors) each agreed to censure and pay a fine to the SEC to settle the dispute and avoid suspension of their ability to practice before the SEC and audit U.S. listed companies. The settlement requires the firms to follow detailed procedures and to seek to provide the SEC with access to the Chinese firms' audit documents via the CSRC. If future document productions fail to meet the specified criteria, the SEC retains the authority to impose a variety of additional measures (e.g., imposing penalties such as suspensions, restarting the administrative proceedings).

In the event that the SEC restarts the administrative proceedings, depending upon the final outcome, listed companies in the United States with major PRC operations may find it difficult or impossible to retain auditors in respect of their operations in the PRC, which could result in financial statements being determined to not be in compliance with the requirements of the Exchange Act, and

could result in delisting. Moreover, any negative news about the proceedings against these audit firms may cause investor uncertainty regarding China-based, United States-listed companies and the market price of our shares may be adversely affected. If our independent registered public accounting firm was denied, temporarily, the ability to practice before the SEC and we were unable to timely find another registered public accounting firm to audit and issue an opinion on our financial statements, our financial statements could be determined to not be in compliance with the requirements of the Exchange Act.

An active trading market for our ordinary shares or our ADSs may not develop and the trading price for our ADSs may fluctuate significantly.

We intend to apply to list our ADSs on the [New York Stock Exchange/Nasdaq Global Select Market]. We have no current intention to seek a listing for our ordinary shares on any stock exchange. Prior to the completion of this offering, there has been no public market for our ADSs or our ordinary shares, and we cannot assure you that a liquid public market for our ADSs will develop. If an active public market for our ADSs does not develop following the completion of this offering, the market price and liquidity of our ADSs may be materially and adversely affected. The initial public offering price for our ADSs was determined by negotiation between us and the underwriters based upon several factors, and we can provide no assurance that the trading price of our ADSs after this offering will not decline below the initial public offering price. As a result, investors in our securities may experience a significant decrease in the value of their ADSs.

The trading price of our ADSs is likely to be volatile, which could result in substantial losses to investors.

The trading price of our ADSs is likely to be volatile and could fluctuate widely due to factors beyond our control. This may happen because of broad market and industry factors, including the performance and fluctuation of the market prices of other companies with operations located mainly in China that have listed their securities in the United States. In addition to market and industry factors, the price and trading volume for our ADSs may be highly volatile for factors specific to our own operations, including the following:

Any of these factors may result in large and sudden changes in the volume and price at which our ADSs will trade.

In the past, shareholders of public companies have often brought securities class action suits against those companies following periods of instability in the market price of their securities. If we were involved in a class action suit, it could divert a significant amount of our management's attention and other resources from our business and require us to incur significant expenses to defend the suit, which could harm our results of operations. Any such class action suit, whether or not successful, could harm our reputation and restrict our ability to raise capital in the future. In addition, if a claim is successfully made against us, we may be required to pay significant damages, which could have a material adverse effect on our financial condition and results of operations.

If securities or industry analysts do not publish research or reports about our business, or if they adversely change their recommendations regarding our ADSs, the market price for our ADSs and trading volume could decline.

The trading market for our ADSs will be influenced by research or reports that industry or securities analysts publish about our business. If one or more analysts who cover us downgrade our ADSs, the market price for our ADSs would likely decline. If one or more of these analysts cease to cover us or fail to regularly publish reports on us, we could lose visibility in the financial markets, which in turn could cause the market price or trading volume for our ADSs to decline.

The sale or availability for sale of substantial amounts of our ADSs could adversely affect their market price.

Sales of substantial amounts of our ADSs in the public market after the completion of this offering, or the perception that these sales could occur, could adversely affect the market price of our ADSs and could materially impair our ability to raise capital through equity offerings in the future. The ADSs sold in this offering will be freely tradable without restriction or further registration under the Securities Act, and shares held by our existing shareholders may also be sold in the public market in the future subject to the restrictions in Rule 144 and Rule 701 under the Securities Act and the applicable lock-up agreements. There will be ADSs (equivalent to ordinary shares) outstanding immediately after this offering. [In connection with this offering, we and our officers, directors, existing shareholders, certain holders of our share-based awards have agreed not to sell any ordinary shares or ADSs for 180 days after the date of this prospectus without the prior written consent of the underwriters, subject to certain exceptions.] However, the underwriters may release these securities from these restrictions at any time, subject to applicable regulations of the Financial Industry Regulatory Authority, Inc. We cannot predict what effect, if any, market sales of securities held by our significant shareholders or any other shareholder or the availability of these securities for future sale will have on the market price of our ADSs. See "Underwriting" and "Shares Eligible for Future Sales" for a more detailed description of the restrictions on selling our securities after this offering.

Because we do not expect to pay dividends in the foreseeable future after this offering, you must rely on price appreciation of our ADSs for return on your investment.

We currently intend to retain most, if not all, of our available funds and any future earnings after this offering to fund the development and growth of our business. As a result, we do not expect to pay any cash dividends in the foreseeable future. Therefore, you should not rely on an investment in our ADSs as a source for any future dividend income.

Our board of directors has complete discretion as to whether to distribute dividends, subject to certain requirements of Cayman Islands law. Even if our board of directors decides to declare and pay dividends, the timing, amount and form of future dividends, if any, will depend on, among other things, our future results of operations and cash flow, our capital requirements and surplus, the amount of

distributions, if any, received by us from our subsidiaries, our financial condition, contractual restrictions and other factors deemed relevant by our board of directors. Accordingly, the return on your investment in our ADSs will likely depend entirely upon any future price appreciation of our ADSs. There is no guarantee that our ADSs will appreciate in value after this offering or even maintain the price at which you purchased the ADSs. You may not realize a return on your investment in our ADSs and you may even lose your entire investment in our ADSs.

We have not determined a specific use for a portion of the net proceeds from this offering, and we may use these proceeds in ways with which you may not agree.

We have not determined a specific use for a portion of the net proceeds of this offering, and our management will have considerable discretion in deciding how to apply these proceeds. You will not have the opportunity to assess whether the proceeds are being used appropriately before you make your investment decision. You must rely on the judgment of our management regarding the application of the net proceeds of this offering. We cannot assure you that the net proceeds will be used in a manner that would improve our results of operations or increase our ADS price, nor that these net proceeds will be placed only in investments that generate income or appreciate in value.

You may be subject to PRC income tax on dividends from us or on any gain realized on the transfer of our ADSs.

Under the PRC Enterprise Income Tax Law and its implementation rules, subject to any applicable tax treaty or similar arrangement between China and your jurisdiction of residence that provides for a different income tax arrangement, PRC withholding tax at the rate of 10% is normally applicable to dividends from PRC sources payable to investors that are non-PRC resident enterprises, which do not have an establishment or place of business in China, or which have such establishment or place of business if the relevant income is not effectively connected with the establishment or place of business. Any gain realized on the transfer of ADSs or ordinary shares by such non-PRC resident enterprise investors is also subject to 10% PRC income tax if such gain is regarded as income derived from sources within China, unless a tax treaty or similar arrangement provides otherwise. Under the PRC Individual Income Tax Law and its implementation rules, dividends from sources within China paid to foreign individual investors who are not PRC residents are generally subject to a PRC withholding tax at a rate of 20% and gains from PRC sources realized by such investors on the transfer of ADSs or ordinary shares are generally subject to 20% PRC income tax, in each case, subject to any reduction or exemption set forth in applicable tax treaties and similar arrangements and PRC laws. Although substantially all of our business operations are in China, it is unclear whether dividends we pay with respect to our ADSs, or the gain realized from the transfer of our ADSs, would be treated as income derived from sources within China and as a result be subject to PRC income tax if we were considered a PRC resident enterprise, as described above. See "Risk Factors—Risks Related to Doing Business in China—Under the PRC Enterprise Income Tax Law, we may be classified as a PRC resident enterprise, which could result in unfavorable tax consequences to us and our shareholders and have a material adverse effect on our results of operations and the value of your investment." If PRC income tax were imposed on gains realized through the transfer of our ADSs or on dividends paid to our non-PRC resident investors, the value of your investment in our ADSs may be materially and adversely affected. Furthermore, our ADS holders whose jurisdictions of residence have tax treaties or similar arrangements with China may not qualify for benefits under such tax treaties or arrangements.

There can be no assurance that we will not be a passive foreign investment company, or PFIC, for U.S. federal income tax purposes for any taxable year, which could result in adverse U.S. federal income tax consequences to U.S. Holders of our ADSs or ordinary shares.

A non-U.S. corporation will be a PFIC for any taxable year if either (i) at least 75% of its gross income for such year consists of certain types of "passive" income; or (ii) at least 50% of the value of its assets (based on an average of the quarterly values of the assets) during such year is attributable to assets that produce passive income or are held for the production of passive income (the "asset test"). Although the law in this regard is unclear, we intend to treat our VIEs as being owned by us for U.S. federal income tax purposes, not only because we exercise effective control over the operation of these entities but also because we are entitled to substantially all of their economic benefits, and, as a result, we consolidate their results of operations in our consolidated financial statements. Assuming that we are the owner of our VIEs for U.S. federal income tax purposes, and based on our current and expected income and assets (taking into account the expected cash proceeds and our anticipated market capitalization following this offering), we do not presently expect to be a PFIC for the current taxable year or the foreseeable future. However, no assurance can be given in this regard because the determination of whether we are or will become a PFIC is a fact-intensive inquiry made on an annual basis that depends, in part, upon the composition of our income and assets. Fluctuations in the market price of our ADSs may cause us to become a PFIC for the current or subsequent taxable years because the value of our assets for the purpose of the asset test may be determined by reference to the market price of our ADSs. The composition of our income and assets may also be affected by how, and how quickly, we use our liquid assets and the cash raised in this offering. In addition, if it were determined that we do not own the stock of our VIEs for U.S. federal income tax purposes, our risk of being a PFIC may substantially increase.

If we are a PFIC in any taxable year, a U.S. Holder (as defined in "Taxation—U.S. Federal Income Tax Considerations") may incur significantly increased U.S. federal income tax on gain recognized on the sale or other disposition of the ADSs or ordinary shares and on the receipt of distributions on the ADSs or ordinary shares to the extent such gain or distribution is treated as an "excess distribution" under U.S. federal income tax rules and such holder may be subject to burdensome reporting requirements. Further, if we are a PFIC for any year during which a U.S. Holder holds our ADSs or ordinary shares, we generally will continue to be treated as a PFIC for all succeeding years during which such U.S. Holder holds our ADSs or ordinary shares. See "Taxation—U.S. Federal Income Tax Considerations—Passive Foreign Investment Company Rules."

The approval of the CSRC may be required in connection with this offering under PRC law.

The M&A Rules, which were adopted in 2006 by six PRC regulatory agencies, including the CSRC, and amended in 2009, purport to require offshore special purpose vehicles that are controlled by PRC companies or individuals and that have been formed for the purpose of seeking a public listing on an overseas stock exchange through acquisitions of PRC domestic companies or assets to obtain CSRC approval prior to publicly listing their securities on an overseas stock exchange. On September 21, 2006, the CSRC published on its official website procedures regarding its approval of overseas listings by special purpose vehicles. The interpretation and application of the regulations remain unclear, and this offering may ultimately require approval from the CSRC. If CSRC approval is required, it is uncertain how long it will take us to obtain the approval. Any failure to obtain or delay in obtaining CSRC approval for this offering would subject us to sanctions imposed by the CSRC and other PRC regulatory agencies, which could include fines and penalties on our operations in China, restrictions or limitations on our ability to pay dividends outside of China, and other forms of sanctions that may materially and adversely affect our business, results of operations and financial condition.

Our PRC counsel, Commerce & Finance Law Offices, has advised us that, based on its understanding of the current PRC laws and regulations, we are not required to submit an application to

the CSRC for the approval of the listing and trading of our ADSs on the [New York Stock Exchange/Nasdaq Global Select Market] because (i) the CSRC currently has not issued any definitive rule or interpretation concerning whether offerings like ours under this prospectus are subject to this regulation, and (ii) our wholly owned PRC subsidiaries were directly established by us as wholly foreign-owned enterprises, and we have not acquired any equity interest or assets of a PRC domestic company owned by PRC companies or individuals as defined under the M&A Rules that are our beneficial owners after the effective date of the M&A Rules, and no provision in the M&A Rules clearly classifies the contractual arrangements among Hode Technology, our VIEs and their shareholders as a type of transaction subject to the M&A Rules. However, we cannot assure you that relevant PRC government agencies, including the CSRC, would reach the same conclusion as our PRC counsel, and hence we may face regulatory actions or other sanctions from the CSRC or other PRC regulatory agencies. These regulatory agencies may impose fines and penalties on our operations in China, limit our operating privileges in China, delay or restrict the repatriation of the proceeds from this offering into China or take other actions that could have a material adverse effect on our business, financial condition, results of operations and prospects, as well as the trading price of the ADSs. The CSRC or other PRC regulatory agencies also may take actions requiring us, or making it advisable for us, to halt this offering before settlement and delivery of the ADSs offered hereby. Consequently, if you engage in market trading or other activities in anticipation of and prior to settlement and delivery, you do so at the risk that settlement and delivery may not occur. In addition, if the CSRC or other regulatory agencies later promulgate new rules or explanations requiring that we obtain their approvals for this offering, we may be unable to obtain a waiver of such approval requirements, if and when procedures are established to obtain such a waiver. Any uncertainties and/or negative publicity regarding such approval requirement could have a material adverse effect on the trading price of the ADSs.

Our memorandum and articles of association contain anti-takeover provisions that could have a material adverse effect on the rights of holders of our ordinary shares and ADSs.

We will adopt amended and restated memorandum and articles of association that will become effective immediately prior to the completion of this offering. Our new memorandum and articles of association contain provisions to limit the ability of others to acquire control of our company or cause us to engage in change-of-control transactions. These provisions could have the effect of depriving our shareholders of an opportunity to sell their shares at a premium over prevailing market prices by discouraging third parties from seeking to obtain control of our company in a tender offer or similar transaction. In addition, our board of directors has the authority, without further action by our shareholders, to issue preferred shares in one or more series and to fix their designations, powers, preferences, privileges, and relative participating, optional or special rights and the qualifications, limitations or restrictions, including dividend rights, conversion rights, voting rights, terms of redemption and liquidation preferences, any or all of which may be greater than the rights associated with our ordinary shares, in the form of ADS or otherwise. Preferred shares could be issued quickly with terms calculated to delay or prevent a change in control of our company or make removal of management more difficult. If our board of directors decides to issue preferred shares, the price of our ADSs may fall and the voting and other rights of the holders of our ordinary shares and ADSs may be materially and adversely affected.

You may face difficulties in protecting your interests, and your ability to protect your rights through U.S. courts may be limited, because we are incorporated under Cayman Islands law.

We are an exempted company limited by shares registered under the laws of the Cayman Islands. Our corporate affairs are governed by our memorandum and articles of association, the Companies Law (2016 Revision) of the Cayman Islands and the common law of the Cayman Islands. The rights of shareholders to take action against the directors, actions by minority shareholders and the fiduciary

responsibilities of our directors to us under Cayman Islands law are to a large extent governed by the common law of the Cayman Islands. The common law of the Cayman Islands is derived in part from comparatively limited judicial precedent in the Cayman Islands as well as from the common law 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 responsibilities of our directors under Cayman Islands law are not as clearly established as they would be under statutes or judicial precedent in some jurisdictions in the United States. In particular, the Cayman Islands has a less developed body of securities laws than the United States. Some U.S. states, such as Delaware, have more fully developed and judicially interpreted bodies of corporate law than the Cayman Islands. In addition, Cayman Islands companies may not have standing to initiate a shareholder derivative action in a federal court of the United States.

Shareholders of Cayman Islands exempted companies like us have no general rights under Cayman Islands law to inspect corporate records or to obtain copies of lists of shareholders of these companies. Our directors have discretion under our articles of association to determine whether or not, and under what conditions, our corporate records may be inspected by our shareholders, but are not obliged to make them available to our shareholders. This may make it more difficult for you to obtain the information needed to establish any facts necessary for a shareholder motion or to solicit proxies from other shareholders in connection with a proxy contest.

As a result of all of the above, public shareholders may have more difficulty in protecting their interests in the face of actions taken by management, members of the board of directors or controlling shareholders than they would as public shareholders of a company incorporated in the United States. For a discussion of significant differences between the provisions of the Companies Law of the Cayman Islands and the laws applicable to companies incorporated in the United States and their shareholders, see "Description of Share Capital—Differences in Corporate Law."

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

We are a Cayman Islands company and all of our assets are located outside of the United States. Substantially all of our current operations are conducted in China. In addition, a majority of our current directors and officers are nationals and residents of countries other than the United States. Substantially all of the assets of these persons are located outside the United States. As a result, it may be difficult or impossible for you to bring an action against us or against these individuals in the United States in the event that you believe that your rights have been infringed under the U.S. federal securities laws or otherwise. Even if you are successful in bringing an action of this kind, the laws of the Cayman Islands and of China may render you unable to enforce a judgment against our assets or the assets of our directors and officers. For more information regarding the relevant laws of the Cayman Islands and China, see "Enforceability of Civil Liabilities."

We are an emerging growth company within the meaning of the Securities Act and may take advantage of certain reduced reporting requirements.

We are an "emerging growth company," as defined in the JOBS Act, and we may take advantage of certain exemptions from requirements applicable to other public companies that are not emerging growth companies including, most significantly, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002 for so long as we remain an emerging growth company until the fifth anniversary from the date of our initial listing. As a result, if we elect not to comply with such auditor attestation requirements, our investors may not have access to certain information they may deem important.

We will incur increased costs as a result of being a public company, particularly after we cease to qualify as an "emerging growth company."

Upon completion of this offering, we will become a public company and expect to incur significant legal, accounting and other expenses that we did not incur as a private company. The Sarbanes-Oxley Act of 2002, as well as rules subsequently implemented by the SEC and [New York Stock Exchange/Nasdaq Global Select Market], impose various requirements on the corporate governance practices of public companies. As a company with less than US$1.07 billion in revenues for our last fiscal year, we qualify as an "emerging growth company" pursuant to the JOBS Act. An emerging growth company may take advantage of specified reduced reporting and other requirements that are otherwise applicable generally to public companies. These provisions include exemption from the auditor attestation requirement under Section 404 of the Sarbanes-Oxley Act of 2002, in the assessment of the emerging growth company's internal control over financial reporting. The JOBS Act also permits an emerging growth company to delay adopting new or revised accounting standards until such time as those standards apply to private companies. However, we have elected to "opt out" of this provision and, as a result, we will comply with new or revised accounting standards as required when they are adopted for public companies. This decision to opt out of the extended transition period under the JOBS Act is irrevocable.

We expect these rules and regulations to increase our legal and financial compliance costs and to make some corporate activities more time-consuming and costly. After we are no longer an "emerging growth company," we expect to incur significant expenses and devote substantial management effort toward ensuring compliance with the requirements of Section 404 of the Sarbanes-Oxley Act of 2002 and the other rules and regulations of the SEC. For example, as a result of becoming a public company, we will need to increase the number of independent directors and adopt policies regarding internal controls and disclosure controls and procedures. We also expect that operating as a public company will make it more difficult and more expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. In addition, we will incur additional costs associated with our public company reporting requirements. It may also be more difficult for us to find qualified persons to serve on our board of directors or as executive officers. We are currently evaluating and monitoring developments with respect to these rules and regulations, and we cannot predict or estimate with any degree of certainty the amount of additional costs we may incur or the timing of such costs.

As a company incorporated in the Cayman Islands, we are permitted to adopt certain home country practices in relation to corporate governance matters that differ significantly from the [NYSE/Nasdaq] corporate governance listing standards; these practices may afford less protection to shareholders than they would enjoy if we complied fully with the [NYSE/Nasdaq] corporate governance listing standards.

As a Cayman Islands company listed on the [NYSE/Nasdaq Global Select Market], we are subject to the [NYSE/Nasdaq] corporate governance listing standards. However, [NYSE/Nasdaq] rules permit a foreign private issuer like us to follow the corporate governance practices of its home country. Certain corporate governance practices in the Cayman Islands, which is our home country, may differ significantly from [NYSE/Nasdaq] corporate governance listing standards. Currently, we do not plan to rely on home country practice with respect to our corporate governance after we complete this offering. However, if we choose to follow home country practice in the future, our shareholders may be afforded less protection than they would otherwise enjoy under the [NYSE/ Nasdaq] governance listing standards applicable to U.S. domestic issuers.

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 U.S. domestic public companies.

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

We will be required to file an annual report on Form 20-F within four months of the end of each fiscal year. In addition, we intend to publish our results on a quarterly basis through press releases, distributed pursuant to the rules and regulations of the [New York Stock Exchange/Nasdaq Global Select Market]. Press releases relating to financial 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 and less timely compared to that required to be filed with the SEC by U.S. domestic issuers. As a result, you may not be afforded the same protections or information, which would be made available to you, were you investing in a U.S. domestic issuer.

The voting rights of holders of ADSs are limited by the terms of the deposit agreement, and you may not be able to exercise your right to vote your ordinary shares.

Holders of ADSs do not have the same rights as our registered shareholders. As a holder of our ADSs, you will not have any direct right to attend general meetings of our shareholders or to cast any votes at such meetings. You will only be able to exercise the voting rights which are carried by the underlying ordinary shares represented by your ADSs in directly by giving voting instructions to the depositary in accordance with the provisions of the deposit agreement. Under the deposit agreement, you may vote by giving voting instructions to the depositary. Upon receipt of your voting instructions, the depositary will try, as far as is practicable, to vote the ordinary shares underlying your ADSs in accordance with your instructions. If we ask for your instructions, then upon receipt of your voting instructions, the depositary will try to vote the underlying ordinary shares in accordance with these instructions. If we do not instruct the depositary to ask for your instructions, the depositary may still vote in accordance with instructions you give, but it is not required to do so. You will not be able to directly exercise your right to vote with respect to the underlying ordinary shares unless you withdraw the shares, and become the registered holder of such shares prior to the record date for the general meeting. When a general meeting is convened, you may not receive sufficient advance notice of the meeting to withdraw the shares underlying your ADSs and become the registered holder of such shares to allow you to attend the general meeting and to vote directly with respect to any specific matter or resolution to be considered and voted upon at the general meeting. In addition, under our post-offering amended and restated articles of association that will become effective prior to completion of this offering, for the purposes of determining those shareholders who are entitled to attend and vote at any general meeting, our directors may close our register of members and/or fix in advance a record date for such meeting, and such closure of our register of members or the setting of such a record date may prevent you from withdrawing the ordinary shares underlying your ADSs and becoming the registered holder of such shares prior to the record date, so that you would not be able to attend the general

meeting or to vote directly. If we ask for your instructions, the depositary will notify you of the upcoming vote and will arrange to deliver our voting materials to you. We cannot assure you that you will receive the voting materials in time to ensure that you can instruct the depositary to vote the underlying ordinary shares represented by your ADSs. In addition, the depositary and its agents are not responsible for failing to carry out voting instructions or for their manner of carrying out your voting instructions. This means that you may not be able to exercise your right to direct how the shares underlying your ADSs are voted and you may have no legal remedy if the shares underlying your ADSs are not voted as you requested.

You may experience dilution of your holdings due to inability to participate in rights offerings.

We may, from time to time, distribute rights to our shareholders, including rights to acquire securities. Under the deposit agreement, the depositary will not distribute rights to holders of ADSs unless the distribution and sale of rights and the securities to which these rights relate are either exempt from registration under the Securities Act with respect to all holders of ADSs, or are registered under the provisions of the Securities Act. The depositary may, but is not required to, attempt to sell these undistributed rights to third parties, and may allow the rights to lapse. We may be unable to establish an exemption from registration under the Securities Act, and we are under no obligation to file a registration statement with respect to these rights or underlying securities or to endeavor to have a registration statement declared effective. Accordingly, holders of ADSs may be unable to participate in our rights offerings and may experience dilution of their holdings as a result.

Your ADSs are transferable on the books of the depositary. However, the depositary may close its books at any time or from time to time when it deems expedient in connection with the performance of its duties. The depositary may close its books from time to time for a number of reasons, including in connection with corporate events such as a rights offering, during which time the depositary needs to maintain an exact number of ADS holders on its books for a specified period. The depositary may also close its books in emergencies, and on weekends and public holidays. The depositary may refuse to deliver, transfer or register transfers of our ADSs generally when our share register or the books of the depositary are closed, or at any time if we or the depositary thinks it is advisable to do so because of any requirement of law or of any government or governmental body, or under any provision of the deposit agreement, or for any other reason.

This prospectus contains forward-looking statements that reflect our current expectations and views of future events. The forward looking statements are contained principally in the sections entitled "Prospectus Summary," "Risk Factors," "Management's Discussion and Analysis of Financial Condition and Results of Operations" and "Business." Known and unknown risks, uncertainties and other factors, including those listed under "Risk Factors," may cause our actual results, performance or achievements to be materially different from those expressed or implied by the forward-looking statements.

You can identify some of these forward-looking statements by words or phrases such as "may," "will," "expect," "anticipate," "aim," "estimate," "intend," "plan," "believe," "is/are likely to," "potential," "continue" or other similar expressions. We have based these forward-looking statements largely on our current expectations and projections about future events that we believe may affect our financial condition, results of operations, business strategy and financial needs. These forward-looking statements include statements relating to:

These forward-looking statements involve various risks and uncertainties. Although we believe that our expectations expressed in these forward-looking statements are reasonable, our expectations may later be found to be incorrect. Our actual results could be materially different from our expectations. Important risks and factors that could cause our actual results to be materially different from our expectations are generally set forth in "Prospectus Summary—Our Challenges," "Risk Factors," "Management's Discussion and Analysis of Financial Condition and Results of Operations," "Business," "Regulation" and other sections in this prospectus. You should read thoroughly this prospectus and the documents that we refer to with the understanding that our actual future results may be materially different from and worse than what we expect. We qualify all of our forward-looking statements by these cautionary statements.

This prospectus contains certain data and information that we obtained from various government and private publications. Statistical data in these publications also include projections based on a number of assumptions. The online entertainment industry may not grow at the rate projected by market data, or at all. Failure of this market to grow at the projected rate may have a material and adverse effect on our business and the market price of our ADSs. In addition, the rapidly evolving nature of the online entertainment industry results in significant uncertainties for any projections or estimates relating to the growth prospects or future condition of our market. Furthermore, if any one or more of the assumptions underlying the market data are later found to be incorrect, actual results may differ from the projections based on these assumptions. You should not place undue reliance on these forward-looking statements.

The forward-looking statements made in this prospectus relate only to events or information as of the date on which the statements are made in this prospectus. Except as required by law, we undertake no obligation to update or revise publicly any forward-looking statements, whether as a result of new information, future events or otherwise, after the date on which the statements are made or to reflect the occurrence of unanticipated events. You should read this prospectus and the documents that we refer to in this prospectus and have filed as exhibits to the registration statement, of which this prospectus is a part, completely and with the understanding that our actual future results may be materially different from what we expect.

We estimate that we will receive net proceeds from this offering of approximately US$ , or approximately US$ if the underwriters exercise their over-allotment option in full, after deducting underwriting discounts and the estimated offering expenses payable by us. These estimates are based upon an assumed initial public offering price of US$ per ADS, the mid-point of the price range shown on the front cover page of this prospectus. A US$1.00 increase (decrease) in the assumed initial public offering price of US$ per ADS would increase (decrease) the net proceeds to us from this offering by US$ , assuming no change to the number of ADSs offered by us as set forth on the cover page of this prospectus, and after deducting the estimated underwriting discounts and commissions and estimated expenses payable by us.

The primary purposes of this offering are to create a public market for our shares for the benefit of all shareholders, retain talented employees by providing them with equity incentives, and obtain additional capital. We plan to use the net proceeds of this offering as follows:

The foregoing represents our current intentions based upon our present plans and business conditions to use and allocate the net proceeds of this offering. Our management, however, will have significant flexibility and discretion to apply the net proceeds of this offering. If an unforeseen event occurs or business conditions change, we may use the proceeds of this offering differently than as described in this prospectus. See "Risk Factors—Risks Related to Our ADSs and This Offering—We have not determined a specific use for a portion of the net proceeds from this offering, and we may use these proceeds in ways with which you may not agree."

Pending any use described above, we plan to invest the net proceeds in short-term, interest-bearing, debt instruments.

In using the proceeds of this offering, we are permitted under PRC laws and regulations as an offshore holding company to provide funding to our PRC subsidiaries only through loans or capital contributions and to our VIEs only through loans, subject to satisfaction of applicable government registration and approval requirements. We cannot assure you that we will be able to obtain these government registrations or approvals on a timely basis, if at all. See "Risk Factors—Risks Related to Doing Business in China—PRC regulation of loans to, and direct investment in, PRC entities by offshore holding companies and governmental control of currency conversion may restrict or prevent us from using the proceeds of our initial public offering to make loans to our PRC subsidiaries and our VIEs and their subsidiaries, or to make additional capital contributions to our PRC subsidiaries."

Our board of directors has complete discretion on whether to distribute dividends, subject to certain requirements of Cayman Islands law. Even if our board of directors decides to pay dividends, the form, frequency and amount will depend upon our future operations and earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that the board of directors may deem relevant.

We do not have any present plan to pay any cash dividends on our ordinary shares in the foreseeable future after this offering. We currently intend to retain most, if not all, of our available funds and any future earnings to operate and expand our business.

We are a holding company incorporated in the Cayman Islands. We may rely on dividends from our subsidiaries in China for our cash requirements, including any payment of dividends to our shareholders. PRC regulations may restrict the ability of our PRC subsidiaries to pay dividends to us. See "Regulation—Regulations Related to Dividend Distributions."

If we pay any dividends on our ordinary shares, we will pay those dividends which are payable in respect of the ordinary shares underlying our ADSs to the depositary, as the registered holder of such ordinary shares, and the depositary then will pay such amounts to our ADS holders in proportion to ordinary shares underlying the ADSs held by such ADS holders, subject to the terms of the deposit agreement, including the fees and expenses payable thereunder. See "Description of American Depositary Shares." Cash dividends on our ordinary shares, if any, will be paid in U.S. dollars.

Unaudited pro forma basic and diluted net loss per ordinary share reflects the effect of the conversion of preferred shares and other permanent equities as follows, as if the conversion occurred as of the beginning of the period or the original date of issuance, if later.

You should read this table together with our consolidated financial statements and the related notes included elsewhere in this prospectus and the information under "Management's Discussion and Analysis of Financial Condition and Results of Operations."

If you invest in our ADSs, your interest will be diluted to the extent of the difference between the initial public offering price per ADS and our net tangible book value per ADS after this offering. Dilution results from the fact that the initial public offering price per ordinary share is substantially in excess of the book value per ordinary share attributable to the existing shareholders for our presently outstanding ordinary shares.

Our net tangible book value as of September 30, 2017 was approximately US$ , or US$ per ordinary share as of that date and US$ per ADS. Net tangible book value represents the amount of our total consolidated tangible assets, less the amount of our total consolidated liabilities. Dilution is determined by subtracting net tangible book value per ordinary share, after giving effect to the additional proceeds we will receive from this offering, from the assumed initial public offering price of US$ per ordinary share, which is the midpoint of the estimated initial public offering price range set forth on the cover page of this prospectus adjusted to reflect the ADS-to-ordinary share ratio, and after deducting underwriting discounts and commissions and estimated offering expenses payable by us.

Without taking into account any other changes in net tangible book value after September 30, 2017, other than to give effect to our sale of the ADSs offered in this offering at the assumed initial public offering price of US$ per ADS, the midpoint of the estimated range of the initial public offering price, after deduction of the underwriting discounts and commissions and estimated offering expenses payable by us, our pro forma as adjusted net tangible book value as of September 30, 2017 would have been US$ , or US$ per ordinary share and US$ per ADS. This represents an immediate increase in net tangible book value of US$ per ordinary share and US$ per ADS to the existing shareholders and an immediate dilution in net tangible book value of US$ per ordinary share and US$ per ADS to investors purchasing ADSs in this offering. The following table illustrates such dilution:

A US$1.00 increase (decrease) in the assumed public offering price of US$ per ADS would increase (decrease) our pro forma as adjusted net tangible book value after giving effect to this offering by US$ , the pro forma as adjusted net tangible book value per ordinary share and per ADS after giving effect to this offering by US$ per ordinary share and US$ per ADS and the dilution in pro forma as adjusted net tangible book value per ordinary share and per ADS to new investors in this offering by US$ per ordinary share and US$ per ADS, assuming no change to the number of ADSs offered by us as set forth on the cover page of this prospectus, and after deducting underwriting discounts and commissions and other offering expenses.

The following table summarizes, on a pro forma as adjusted basis as of September 30, 2017, the differences between existing shareholders and the new investors with respect to the number of ordinary shares (in the form of ADSs or shares) purchased from us, the total consideration paid and the average price per ordinary share and per ADS paid before deducting the underwriting discounts and

commissions and estimated offering expenses. The total number of ordinary shares does not include ordinary shares underlying the ADSs issuable upon the exercise of the over-allotment option granted to the underwriters.

The pro forma as adjusted information discussed above is illustrative only. Our net tangible book value following the completion of this offering is subject to adjustment based on the actual initial public offering price of our ADSs and other terms of this offering determined at pricing.

As of the date of this prospectus, there are 19,409,209 ordinary shares issuable upon exercise of outstanding share options at a nominal exercise price. To the extent that any of these options other than ordinary shares issuable upon exercise of outstanding share options granted to directors and senior management are exercised, there will be further dilution to new investors.

Our reporting currency is the Renminbi because our business is mainly conducted in China and all of our revenues are denominated in Renminbi. This prospectus contains translations of Renminbi amounts into U.S. dollars at specific rates solely for the convenience of the reader. The conversion of Renminbi into U.S. dollars in this prospectus is based on the exchange rate set forth in the H.10 statistical release of the Board of Governors of the Federal Reserve System. Unless otherwise noted, all translations from Renminbi to U.S. dollars and from U.S. dollars to Renminbi in this prospectus were made at a rate of RMB6.6533 to US$1.00, the exchange rate on September 29, 2017 set forth in the H.10 statistical release of the Board of Governors of the Federal Reserve System. We make no representation that any Renminbi or U.S. dollar amounts could have been, or could be, converted into U.S. dollars or Renminbi, as the case may be, at any particular rate, the rates stated below, or at all. The PRC government imposes control over its foreign currency reserves in part through direct regulation of the conversion of Renminbi into foreign exchange and through restrictions on foreign trade. On February 9, 2018, the exchange rate for Renminbi was RMB6.2966 to US$1.00.

The following table sets forth information concerning exchange rates between the Renminbi and the U.S. dollar for the periods indicated. These rates are provided solely for your convenience and are not necessarily the exchange rates that we used in this prospectus or will use in the preparation of our periodic reports or any other information to be provided to you.

We are incorporated under the laws of the Cayman Islands as an exempted company with limited liability. We are incorporated in the Cayman Islands because of certain benefits associated with being a Cayman Islands exempted company, such as political and economic stability, an effective judicial system, a favorable tax system, the absence of foreign exchange control or currency restrictions and the availability of professional and support services. However, the Cayman Islands has a less developed body of securities laws than the United States and provides less protection for investors. In addition, Cayman Islands companies do not have standing to sue before the federal courts of the United States.

Substantially all of our assets are located outside the United States. In addition, most of our directors and officers are nationals or residents of jurisdictions other than the United States and all or a substantial portion of their assets are located outside the United States. As a result, it may be difficult for investors to effect service of process within the United States upon us or these persons, or to enforce judgments obtained in U.S. courts against us or them, including judgments predicated upon the civil liability provisions of the securities laws of the United States or any state in the United States. It may also be difficult for you to enforce judgments obtained in U.S. courts based on the civil liability provisions of the U.S. federal securities laws against us and our officers and directors.

We have appointed [Law Debenture Corporate Services Inc.] as our agent to receive service of process with respect to any action brought against us in the U.S. District Court for the Southern District of New York in connection with this offering under the federal securities laws of the United States or the securities laws of any State in the United States or any action brought against us in the Supreme Court of the State of New York in the County of New York in connection with this offering under the securities laws of the State of New York.

Walkers, our counsel as to Cayman Islands law, has advised us that there is uncertainty as to whether the courts of the Cayman Islands would (1) recognize or enforce judgments of U.S. courts obtained against us or our directors or officers that are predicated upon the civil liability provisions of the federal securities laws of the United States or the securities laws of any state in the United States, or (2) entertain original actions brought in the Cayman Islands against us or our directors or officers that are predicated upon the federal securities laws of the United States or the securities laws of any state in the United States.

Walkers has informed us that although there is no statutory enforcement in the Cayman Islands of judgments obtained in the federal or state courts of the United States (and the Cayman Islands are not a party to any treaties for the reciprocal enforcement or recognition of such judgments), a judgment in personam obtained in such jurisdiction will be recognized and enforced in the courts of the Cayman Islands at common law, without any re-examination of the merits of the underlying dispute, by an action commenced on the foreign judgment debt in the Grand Court of the Cayman Islands, provided such judgment (i) is given by a competent foreign court with jurisdiction to give the judgment, (ii) imposes a specific positive obligation on the judgment debtor (such as an obligation to pay a liquidated sum or perform a specified obligation), (iii) is final and conclusive, (iv) is not in respect of taxes, a fine or a penalty; and (v) was not obtained in a manner and is not of a kind the enforcement of which is contrary to natural justice or the public policy of the Cayman Islands. However, the Cayman Islands courts are unlikely to enforce a judgment obtained from the U.S. courts under civil liability provisions of the U.S. federal securities law if such judgment is determined by the courts of the Cayman Islands to give rise to obligations to make payments that are penal or punitive in nature. Because such a determination has not yet been made by a court of the Cayman Islands, it is uncertain whether such civil liability judgments from U.S. courts would be enforceable in the Cayman Islands.

Commerce & Finance Law Offices, our counsel as to PRC law, has advised us that there is uncertainty as to whether the courts of China would (1) recognize or enforce judgments of United States courts obtained against us or our directors or officers predicated upon the civil liability

provisions of the securities laws of the United States or any state in the United States, or (2) entertain original actions brought in each respective jurisdiction against us or our directors or officers predicated upon the securities laws of the United States or any state in the United States.

Commerce & Finance Law Offices has further advised us that the recognition and enforcement of foreign judgments are provided for under the PRC Civil Procedures Law. PRC courts may recognize and enforce foreign judgments in accordance with the requirements of the PRC Civil Procedures Law based either on treaties between China and the country where the judgment is made or on principles of reciprocity between jurisdictions. China does not have any treaties or other form of reciprocity with the United States or the Cayman Islands that provide for the reciprocal recognition and enforcement of foreign judgments. In addition, according to the PRC Civil Procedures Law, courts in China will not enforce a foreign judgment against us or our directors and officers if they decide that the judgment violates the basic principles of PRC law or national sovereignty, security or public interest. As a result, it is uncertain whether and on what basis a PRC court would enforce a judgment rendered by a court in the United States or in the Cayman Islands. Under the PRC Civil Procedures Law, foreign shareholders may originate actions based on PRC law against a company in China for disputes relating to contracts or other property interests, the PRC court may accept a course of action based on the laws or the parties' express mutual agreement in contracts choosing PRC courts for dispute resolution if (i) the contract is signed and/or performed within China, (ii) the subject of the action is located within China, (iii) the company (as defendant) has seizable properties within China, (iv) the company has a representative organization within China, or (v) other circumstances prescribed under the PRC law. The action may be initiated by a shareholder through filing a complaint with the PRC court. The PRC court will determine whether to accept the complaint in accordance with the PRC Civil Procedures Law. The shareholder may participate in the action by itself or entrust any other person or PRC legal counsel to participate on behalf of such shareholder. Foreign citizens and companies will have the same rights as PRC citizens and companies in an action unless the home jurisdiction of such foreign citizens or companies restricts the rights of PRC citizens and companies.

In addition, it will be difficult for U.S. shareholders to originate actions against us in China in accordance with PRC laws because we are incorporated under the laws of the Cayman Islands and it will be difficult for U.S. shareholders, by virtue only of holding our ADSs or ordinary shares, to establish a connection to China for a PRC court to have jurisdiction as required under the PRC Civil Procedures Law.

Due to restrictions imposed by PRC laws and regulations on foreign ownership of companies that engage in internet and other related business, our WFOE later entered into a series of contractual arrangements with Shanghai Hode and Shanghai Kuanyu, which two entities we collectively refer to as our VIEs in this prospectus, and their respective shareholders. For more details, please see "—Contractual Arrangements with Our VIEs and Their Respective Shareholders." As a result of our direct ownership in our WFOE and the variable interest entity contractual arrangements, we are regarded as the primary beneficiary of our VIEs. We treat them and their subsidiaries as our consolidated affiliated entities under U.S. GAAP., and have consolidated the financial results of these entities in our consolidated financial statements in accordance with U.S. GAAP.

The following diagram illustrates our corporate structure, including our principal subsidiaries and our VIEs and their respective principal subsidiaries, as of the date of this prospectus:

The following is a summary of the currently effective contractual arrangements by and among our wholly-owned subsidiary, Hode Technology (our WFOE), our VIEs and their respective shareholders. These contractual arrangements enable us to (i) exercise effective control over our VIEs; (ii) receive substantially all of the economic benefits of our VIEs; and (iii) have an exclusive option to purchase all or part of the equity interests in and assets of them when and to the extent permitted by PRC law.

Powers of Attorney. On June 2, 2015, Mr. Rui Chen, the shareholder of Shanghai Kuanyu, executed a power of attorney to irrevocably appoint Hode Technology or its designated person as his attorney-in-fact to exercise all of his rights as a shareholder of Shanghai Kuanyu, including, but not limited to, the right to convene and attend shareholders' meeting, vote on any resolution that requires a shareholder vote, such as the appointment or removal of directors and executive officers, and other voting rights pursuant to the then-effective articles of association of Shanghai Kuanyu. The power of attorney will remain in force for so long as the shareholder remains a shareholder of Shanghai Kuanyu.

However, we have been further advised by our PRC legal counsel that there are substantial uncertainties regarding the interpretation and application of current and future PRC laws, regulations and rules. Accordingly, the PRC regulatory authorities may in the future take a view that is contrary to or otherwise different from the above opinion of our PRC legal counsel. If the PRC government finds that the agreements that establish the structure for operating our online entertainment business do not comply with PRC government restrictions on foreign investment in our businesses, we could be subject to severe penalties including being prohibited from continuing operations. See "Risk Factors—Risks Related to Our Corporate Structure—We rely on contractual arrangements with our VIEs and their shareholders for our operations in China, which may not be as effective in providing operational control as direct ownership." and "Risk Factors—Risks Related to Doing Business in China—If we fail to obtain and maintain the requisite licenses and approvals required under the complex regulatory environment applicable to our businesses in China, or if we are required to take compliance actions that are time-consuming or costly, our business, financial condition and results of operations may be materially and adversely affected."

We use EBITDA, adjusted EBITDA and adjusted net loss, each a non-GAAP financial measure, in evaluating our operating results and for financial and operational decision-making purposes.

We believe that EBITDA, adjusted EBITDA and adjusted net loss help identify underlying trends in our business that could otherwise be distorted by the effect of certain expenses that we include in loss from operations and net loss. We believe that EBITDA, adjusted EBITDA and adjusted net loss provide useful information about our results of operations, enhance the overall understanding of our past performance and future prospects and allow for greater visibility with respect to key metrics used by our management in its financial and operational decision-making.

Adjusted net loss represents net loss excluding share-based compensation expenses and amortization expense related to intangible assets acquired through business acquisition. The table below sets forth a reconciliation of our net loss to adjusted net loss for the periods indicated:

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

You should read the following discussion together with our consolidated financial statements and the related notes included elsewhere in this prospectus. This discussion contains forward-looking statements that involve risks and uncertainties about our business and operations. Our actual results may differ materially from those we currently anticipate as a result of various factors, including those we describe under "Risk Factors" and elsewhere in this prospectus. See "Special Note Regarding Forward-Looking Statements."

We have a young and culturally aspirational user base willing to invest in a high-quality entertainment experience. In the fourth quarter of 2017, we had 71.8 million average MAUs, an increase of 45.3% from 49.4 million in the same period of 2016. Our user base has demonstrated strong engagement and loyalty to our communities. In 2017, the average daily time spent per active user on our mobile app was approximately 76.3 minutes, as compared to 72.2 minutes in 2016.

Our business depends on our ability to grow our user base, and maintain and increase user engagement. We have experienced rapid user growth since our inception. The following table sets forth our average MAUs for each of the quarters indicated:

We have generally achieved continuous growth in our user base during these periods. The decrease in the average MAUs in the fourth quarter of 2017 was primarily attributable to the seasonal effect associated with school holidays as our user base expanded significantly during the summer break of 2017.

We seek to expand our user base and stimulate our users to engage actively on our platform, which incentivizes the growth of PUGC creation and forms the foundation of our business model. We derive a substantial percentage of revenues from our mobile game services, and, to a lesser extent, from live broadcasting and VAS and advertising. In 2017, our average monthly active users for mobile games were 9.1 million, as compared to 3.1 million in 2016, representing an increase of 194%. The number of our users and the level of their engagement on our platform indirectly affect our revenues because the more users we have, the more mobile game players, live broadcasting hosts and advertisers we have. In particular, mobile game user base growth and engagement are primarily driven by the launch of new games and the release of updates of our existing games.

Our revenues and results of operations depend on our ability to monetize our large user base, to convert more users to paying users and to increase the spending of our paying users. Paying users on our platform include users who make payments for various products and services on our platform, including purchases in mobile games offered on our platform, and payments for virtual items in our live broadcasting programs and for VAS. A user who makes payments across different products and services offered on our platform using the same registered account is counted as one paying user.

The following table sets forth our average monthly paying users and average monthly paying users for mobile games for each of the quarters indicated:

The number of average monthly paying users has generally been increasing as we expanded our mobile games operations and diversify our live broadcasting and other value-added services offerings. We started to experience significant growth in the number of average monthly paying users since the fourth quarter of 2016, primarily due to the exclusive launch of Fate/Grand Order in China in September 2016 and the success of this game. However, the number of average monthly paying users and average monthly paying users for mobile games may vary from quarter to quarter and is subject to certain seasonal fluctuations. See "—Selected Quarterly Results of Operations" for additional details regarding the effects of seasonality on our results of operations.

We expect the number of our average monthly paying users to further grow in the near future. However, certain factors inherent in our business and industry could cause our actual results to be materially different from our expectations. See "Risk Factors—Risks Related to Our Business and Industry—If we fail to anticipate user preferences and provide products and services to attract and retain users, or if we fail to keep up with rapid changes in technologies and their impact on user behavior, we may not be able to attract sufficient user traffic to remain competitive, and our business and prospects may be materially and adversely affected."

We are continuing to diversify our product and service offerings and refine our monetization avenues without compromising user experience. We plan to deepen our partnership with third-party game developers to offer more games tailored to our platform and our users and enhance our capabilities to develop games in-house. We also hope to increase revenues from advertising. We will also continue to build our live broadcasting program, VAS, and advertising services, including extending

exclusive cooperation with additional live broadcasting hosts who are popular on our platform, developing more comprehensive marketing solutions for our key account advertisers, and offering more innovative performance-based advertisements and in-program advertisements. Our revenue growth will be affected by our ability to effectively execute our monetization strategies and expand our paying user base.

Our iconic brand, "bilibili", elicits highly favorable sentiments among users and represents the destination for discovering cultural trends and phenomena for young generations in China. Our ability to maintain our prominent market leadership and brand recognition as the leading online entertainment platform is key to our ability to maintain and enhance relationships with our users, content providers, advertisers, game developers and other business partners, and increase our revenues. In addition, the reputation and attractiveness of our platform among young users also serves as a highly efficient marketing channel for our products and services, such as mobile games.

Our results of operations depend on our ability to manage our costs and expenses. Our cost of revenues consists primarily of revenue-sharing costs, content costs, server and bandwidth costs and staff costs. We expect our revenue-sharing costs and content costs will increase in absolute amount as our user base expands and we continue to procure quality content. In addition, we expect the absolute amount of our server and bandwidth costs and our staff costs to increase as we grow our business. We will also invest in the growth by incurring selling and marketing expenses. However, we expect our costs and operating expenses to decrease as a percentage of revenue as we improve operating efficiency.

Our technology is critical for us to retain and attract users, other customers and business partners. We must continue to innovate to keep pace with the growth of our business and bring forward cutting-edge technologies. Our current research and development efforts are primarily focused on enhancing our artificial intelligence technology, big data analytics capabilities and cloud technology, which we believe are crucial for us to integrate and scale our products and services and improve operating efficiency. For example, leveraging our cloud technology, we were able to procure internet bandwidth cost effectively while we increased internet bandwidth capacities to keep up with the growth of our user base and increasing bandwidth needs. In addition, there is a strong demand in China's internet industry for talented and experienced personnel. We must recruit, retain and motivate talented employees while controlling our personnel-related expenses, including share-based compensation expenses.

The following table sets forth the components of our net revenues by amounts and percentages of our total net revenues for the periods presented:

Mobile games. We primarily offer exclusively distributed mobile games and jointly operated mobile games developed by third-party game developers. For exclusively distributed mobile games, we are responsible for game launch, hosting and maintenance of game servers, the operation of in-game promotions and customer services. We also develop localized versions for such games licensed from overseas developers. For jointly operated mobile game services, we offer our mobile game platform for mobile games developed by third-party game developers. We earn game promotion service revenue within the applicable contract periods by providing payment solutions and market promotion services, while game developers are responsible for providing game products, hosting and maintaining game servers and determining the pricing of in-game virtual items. As of December 31, 2017, we operated eight exclusively distributed mobile games and 63 games under joint operating arrangements. Additionally, we also have operated one self-developed game since August 2017. We expect the number of games in all these three categories to increase in the future. Our revenues from mobile games depend on the number of paying users and average revenue per paying user, and ultimately are determined by our ability to select, procure and offer engaging games tailored to our platform and our user preferences.

Live broadcasting and VAS. We generate revenues from our live broadcasting program by sales of in-channel virtual items for use in our live broadcasting program so that users can send them to hosts to show their support. The virtual items sold by us comprise of either consumable items, such as gifts and items that create special visual effects, or time-based items, such as privileges and titles. Under the arrangements with hosts of our live broadcasting program, we share with them a portion of the revenues derived from the sales of virtual items. Meanwhile, we also generate revenues from VAS including membership subscription, paid content and virtual items on our video platform. We expect revenues from live broadcasting and VAS to continue to grow.

Advertising. We generate advertising revenues primarily from display advertising arrangements, and we expect to increase performance-based advertisements and in-program advertisements. Display advertising arrangements allow advertisers to place advertisements on particular areas of our platform, in particular formats and over particular periods. Performance-based advertisements allow advertisers to connect with users who are likely to have demand for the advertisers' products and services based on users' activity and demographic data collected on our platform. We have also worked with our content creators and licensed content providers to offer advertisers in-program advertisements. We expect our advertising revenues to increase in the foreseeable future as we introduce new advertising and marketing solutions and attract more advertisers.

Other services. Our other services primarily consist of sales of products on our e-commerce platform and sales relating to our offline events.

The following table sets forth the components of our cost of revenues by amounts and percentages of cost of revenues for the periods presented:

Revenue-sharing costs consist of fees paid to game developers, distribution channels (app stores) and payment channels, as well as fees we pay to hosts of our live broadcasting program and content creators in accordance with our revenue-sharing arrangements. Content costs consist of amortized costs of purchased licensed content from copyright owners or content distributors. Staff costs consist of salaries and benefits for our employees involved in the operation of our app/websites, mobile game services and live broadcasting program. Server and bandwidth costs are the fees we pay to telecommunication carriers and other service providers for telecommunication services, hosting our servers at their internet data centers, and providing content delivery network and application services.

The following table sets forth the components of our operating expenses by amounts and percentages of operating expenses for the periods presented:

Selling and marketing expenses. Selling and marketing expenses consist primarily of general marketing and promotional expenses, as well as salaries and benefits, including share-based compensation expenses, for our selling and marketing personnel. We expect our selling and marketing

expenses to increase in absolute amounts in the foreseeable future due to increasing investment to maintain our brand awareness and leadership.

General and administrative expenses. General and administrative expenses consist primarily of salaries and expenses, including share-based compensation expenses, professional fees and rental expenses. We expect our general and administrative expenses to increase in absolute amounts in the foreseeable future due to the anticipated growth of our business as well as accounting, insurance, investor relations and other public company costs.

Research and development expenses. Research and development expenses consist primarily of salaries and benefits, including share-based compensation expenses, for research and development personnel dedicated to the development and enhancement of our app/websites and development of online games. We expect our research and development expenses to increase as we expand our research and development team, to enhance our artificial intelligence technology, big data analytics capabilities and cloud technology and develop new features and functionalities on our platform.

The Cayman Islands 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 Cayman Islands except for stamp duties which may be applicable on instruments executed in, or brought within the jurisdiction of the Cayman Islands. In addition, the Cayman Islands does not impose withholding tax on dividend payments.

Our subsidiaries incorporated in Hong Kong, Hode HK and Bilibili HK Limited, are subject to 16.5% Hong Kong profit tax on their taxable income generated from operations in Hong Kong. Under the Hong Kong tax laws, we are exempted from the Hong Kong income tax on our foreign-derived income. In addition, payments of dividends from our Hong Kong subsidiaries to us are not subject to any Hong Kong withholding tax.

Generally, our PRC subsidiaries, VIEs and their subsidiaries are subject to enterprise income tax on their taxable income in China at a statutory rate of 25%. The enterprise income tax is calculated based on the entity's global income as determined under PRC tax laws and accounting standards.

We are subject to value-added tax at a rate of 17% on sales and 6% on the services (research and development services, technology services, information technology services and/or culture and creativity services), in each case less any deductible value-added tax we have already paid or borne. We are also subject to surcharges on value-added tax payments in accordance with PRC law.

Dividends paid by our wholly foreign-owned subsidiaries in China to our intermediary holding company in Hong Kong will be subject to a withholding tax rate of 10%, unless the relevant Hong Kong entity satisfies all the requirements under the Arrangement between China and the Hong Kong Special Administrative Region on the Avoidance of Double Taxation and Prevention of Fiscal Evasion with respect to Taxes on Income and Capital and receives approval from the relevant tax authority. If our Hong Kong subsidiary satisfies all the requirements under the tax arrangement and receives approval from the relevant tax authority, then the dividends paid to the Hong Kong subsidiary would be subject to withholding tax at the standard rate of 5%. Effective from November 1, 2015, the above mentioned approval requirement has been abolished, but a Hong Kong entity is still required to file

application package with the relevant tax authority, and settle the overdue taxes if the preferential 5% tax rate is denied based on the subsequent review of the application package by the relevant tax authority. See "Risk Factors—Risks Related to Our Corporate Structure—We may rely on dividends paid by our PRC subsidiaries to fund cash and financing requirements. Any limitation on the ability of our PRC subsidiaries to pay dividends to us could have a material adverse effect on our ability to conduct our business and to pay dividends to holders of the ADSs and our ordinary shares."

If our holding company in the Cayman Islands or any of our subsidiaries outside of China were deemed to be a "resident enterprise" under the PRC Enterprise Income Tax Law, it would be subject to enterprise income tax on its worldwide income at a rate of 25%. See "Risk Factors—Risks Related to Doing Business in China—Under the PRC Enterprise Income Tax Law, we may be classified as a PRC resident enterprise, which could result in unfavorable tax consequences to us and our shareholders and have a material adverse effect on our results of operations and the value of your investment."

Nine months ended September 30, 2017 compared to nine months ended September 30, 2016

Our net revenues, which consisted of revenues from mobile games, live broadcasting and VAS, advertising and other services, increased by 467% from RMB305.7 million for the nine months ended September 30, 2016 to RMB1,734.7 million (US$260.7 million) for the same period of 2017. This increase was primarily due to increases in revenues from mobile games. Across our platform, our average monthly paying users increased by 258% from approximately 275,600 for the nine months ended September 30, 2016 to approximately 987,100 for the same period of 2017. For mobile games, live broadcasting and VAS, average monthly revenue per paying user increased from approximately RMB93 for the nine months ended September 30, 2016 to approximately RMB176 for the same period in 2017 as a result of our enhanced mobile game operations as well as expanded and diversified live broadcasting offerings.

Mobile games. Our net revenues from mobile games increased substantially from RMB177.7 million for the nine months ended September 30, 2016 to RMB1,440.8 million (US$216.5 million) for the same period of 2017, primarily attributable to a 260% increase in average monthly paying users from approximately 166,200 in the nine months ended September 30, 2016 to approximately 597,500 in the same period of 2017. The increase was primarily due to the increasing popularity of our existing mobile games, particularly the success of Fate/Grand Order, which was launched in September 2016, as well as the launch of new mobile games, such as the launch of Azur Lane in May 2017.

Live broadcasting and VAS. Our net revenues from live broadcasting and VAS increased by 134% from RMB52.5 million for the nine months ended September 30, 2016 to RMB122.8 million (US$18.5 million) for the same period of 2017, mainly attributable to growth in the number and popularity of our hosts as well as an increase in diversity of live broadcasting programs offered on our platform.

Advertising. Our net revenues from advertising increased by 165% from RMB45.0 million for the nine months ended September 30, 2016 to RMB119.4 million (US$17.9 million) for the same period of 2017. This increase was driven by (i) an increase in the number of our average MAUs, and (ii) marketing and promotional efforts undertaken by our marketing team to promote and strengthen our brand and reputation, both of which further enhanced our attractiveness to advertisers.

Others. We had RMB30.5 million and RMB51.8 million (US$7.8 million) of other net revenues for the nine months ended September 30, 2016 and 2017, respectively. The increase was primarily attributable to an increase in sales of products through our e-commerce platform and sales of tickets for our offline events.

Our cost of revenues increased by 157% from RMB530.5 million for the nine months ended September 30, 2016 to RMB1,361.2 million (US$204.6 million) for the same period of 2017 as all components of cost of revenues increased due to our business growth and the expansion of our user base.

Server and bandwidth costs increased by 54.0% from RMB231.2 million for the nine months ended September 30, 2016 to RMB356.1 million (US$53.5 million) for the same period of 2017, primarily due to an increase in server and bandwidth capacity to keep pace with the expansion of our user base and the increase in active users.

Revenue-sharing costs, which primarily consisted of the portion of revenues shared with game developers, certain popular live broadcasting hosts and content creators, increased substantially from

RMB90.6 million for the nine months ended September 30, 2016 to RMB644.5 million (US$96.9 million) for the same period of 2017, primarily due to an increase in payments made to developers of exclusively distributed games, in particular Fate/Grand Order and Azur Lane, and to a lesser extent, due to an increase in payments made to hosts of live broadcasting programs and content creators on our platform.

Content costs increased by 70.6% from RMB101.8 million for the nine months ended September 30, 2016 to RMB173.6 million (US$26.1 million) for the same period of 2017 as we continued to acquire licensed content to expand and diversify our content offerings.

Staff costs increased by 54.4% from RMB59.9 million for the nine months ended September 30, 2016 to RMB92.5 million (US$13.9 million) for the same period of 2017, primarily due to an increase in headcount for employees dedicated to the operations of our app/websites, mobile game services and live broadcasting programs to maintain our service quality and keep pace with the growth of our user base.

As a result of the foregoing, we had gross profit of RMB373.5 million (US$56.1 million) for the nine months ended September 30, 2017, compared to gross loss of RMB224.7 million for the same period of 2016.

General and administrative expenses. Our general and administrative expenses increased slightly by 3.7% from RMB168.7 million for the nine months ended September 30, 2016 to RMB175.0 million (US$26.3 million) for the same period of 2017. The increase was primarily attributable to an increase in rental payments and an increase in average compensation for administrative personnel, partially offset by a decrease in share-based compensation expenses.

Research and development expenses. Our research and development expenses increased by 214% from RMB61.6 million for the nine months ended September 30, 2016 to RMB193.1 million (US$29.0 million) for the same period of 2017, primarily due to an increase in headcount for our research and development personnel dedicated to enhancing our platform operations and mobile game services.

We recorded income tax of RMB6.5 million (US$1.0 million) for the nine months ended September 30, 2017, compared to RMB0.04 million for the same period of 2016.

As a result of the foregoing, we incurred net loss of RMB132.4 million (US$19.9 million) for the nine months ended September 30, 2017, compared to net loss of RMB512.4 million for the same period of 2016.

This increase was primarily due to increases in revenues from mobile games and the increased contribution of revenues from live broadcasting and VAS. Across our platform, our average monthly paying users increased by 367% from approximately 79,900 in 2015 to approximately 373,500 in 2016. For mobile games, live broadcasting and VAS, average monthly revenue per paying user decreased slightly from approximately RMB96 in 2015 to approximately RMB94 in 2016 as we focused on increasing the number of paying users across our platform.

Mobile games. Our net revenues from mobile games increased by 298% from RMB86.1 million in 2015 to RMB342.4 million (US$51.5 million) in 2016, primarily attributable to the launch of Yume-100, a role-playing puzzle mobile game, in December 2015, as well as the launch of Fate/Grand Order in September 2016.

Live broadcasting and VAS. Our net revenues from live broadcasting and VAS increased substantially from RMB6.2 million in 2015 to RMB79.6 million (US$12.0 million) in 2016, mainly attributable to the increase in the number and popularity of our hosts, as well as the expansion of virtual item offerings on our platform.

Advertising. Our net revenues from advertising increased by 221% from RMB18.9 million in 2015 to RMB60.7 million (US$9.1 million) in 2016. This increase was driven by (i) our strengthening brand and market position among young users, which is a particularly attractive demographic group to advertisers, (ii) the significant increase in the number of our average MAUs, making advertising on our platform more attractive, and (iii) the effective efforts of our marketing team in promoting advertising services on our platform.

Others. We had RMB19.7 million and RMB40.5 million (US$6.1 million) of other net revenues in 2015 and 2016 respectively. The increase was primarily attributable to the increase in sales of products through our e-commerce platform and sales of tickets for our offline events.

Our cost of revenues increased by 155% from RMB303.6 million in 2015 to RMB772.8 million (US$116.2 million) in 2016 as all components of cost of revenues increased due to our business growth and the expansion of our user based activity.

Server and bandwidth costs increased by 82.1% from RMB177.2 million in 2015 to RMB322.6 million (US$48.5 million) in 2016, primarily due to an increase in the server capacity required as we provided quality video streaming to an increasing number of users and the number of active users on our platform increased.

Revenue-sharing costs, which primarily consisted of the portion of revenues shared with game developers, certain popular live broadcasting hosts and content creators, increased substantially from RMB17.9 million in 2015 to RMB151.3 million (US$22.7 million) in 2016 primarily due to the increase in sales of virtual items across our platform.

Content costs increased by 217% from RMB46.1 million in 2015 to RMB146.1 million (US$22.0 million) in 2016 as we expanded our licensed content library.

Staff costs increased by 210% from RMB28.6 million to RMB88.6 million (US$13.3 million) in 2016, primarily due to an increase in headcount for employees dedicated to the operation of our app/websites, mobile game services and live broadcasting programs to serve our rapidly growing user base in these areas.

As a result of the foregoing, we incurred gross loss of RMB249.5 million (US$37.5 million) in 2016, compared to gross loss of RMB172.6 million in 2015.

Our total operating expenses increased by 229% from RMB196.3 million in 2015 to RMB645.2 million (US$97.0 million) in 2016, as all components of operating expenses increased due to our business growth and the expansion of our user base.

Selling and marketing expenses.

General and administrative expenses. Our general and administrative expenses increased by 194% from RMB153.7 million in 2015 to RMB451.3 million (US$67.8 million) in 2016. Share-based compensation expense is a large component of our general and administrative expenses, which

increased from RMB100.2 million in 2015 to RMB353.8 million (US$53.2 million) due to awards to our management team members.

Research and development expenses. Our research and development expenses increased by 266% from RMB24.9 million in 2015 to RMB91.2 million (US$13.7 million) in 2016, primarily due to a significant increase in salaries and other benefits for research and development personnel, which was in turn mainly driven by an increase in our research and development staff, especially engineers, from 146 as of December 31, 2015 to 393 as of December 31, 2016.

As a result of the foregoing, we incurred loss from operations of RMB894.7 million (US$134.5 million) in 2016, compared to loss from operations of RMB368.9 million in 2015.

Our net revenues increased substantially in the first three quarters of 2017, compared to the same periods in 2016, primarily due to increases in our revenues from mobile games, which in turn was attributable to the increasing popularity of our existing mobile games, particularly the success of Fate/Grand Order in late 2016, as well as the launch of new mobile games. Growth in other segments also have contributed to a lesser extent to the increase in our net revenues. Across our platform, we believe that our enhanced ability to procure and offer content tailored to our user base resulted in improved monetization. Our cost of revenues also increased substantially in the first three quarters of 2017, compared to the same periods in 2016, especially revenue-sharing costs as we operated more mobile games and hence made more payments to game developers, which was in line with the increase of licensed mobile game revenues. Meanwhile, other components of our cost of revenues and all

components of our operating expenses continued to increase in absolute amounts as we grow our business and expand our user base, but decreased as a percentage of our net revenues due to our increasing economies of scale and improved operating efficiency.

Our results of operations are also subject to seasonal fluctuations. For example, the growth of active users tends to accelerate during school holidays, such as summer and winter breaks, and slow down at the beginning and during certain parts of the school year, as well as the holiday season starting in the fourth quarter and ending with the Chinese New Year holidays, which typically fall in the first half of the first quarter. We conduct marketing campaigns and promotional activities from time to time, which may result in fluctuations in the number of and/or spending by our paying users. Seasonal fluctuations have not thus far posed material operational and financial challenges to us, as such periods tend to be brief and predictable, allowing us to re-allocate resources and improve efficiency ahead of time.

The following table sets forth a summary of our cash flows for the periods presented:

To date, we have financed our operating and investing activities through cash generated by historical equity financing activities. As of December 31, 2015 and 2016 and September 30, 2017, respectively, our cash and cash equivalents were RMB689.7 million, RMB387.2 million (US$58.2 million) and RMB395.4 million (US$59.4 million). Our cash and cash equivalents primarily consist of cash at banks and cash held in accounts with third-party online payment platforms.

We believe that our current cash and cash equivalents and our anticipated cash flows from operations will be sufficient to meet our anticipated working capital requirements and capital expenditures for at least the next 12 months. After this offering, we may decide to enhance our liquidity position or increase our cash reserve for future investments through additional capital and finance funding. The issuance and sale of additional equity would result in further dilution to our

shareholders. The incurrence of indebtedness would result in increased fixed obligations and could result in operating covenants that would restrict our operations. We cannot assure you that financing will be available in amounts or on terms acceptable to us, if at all.

As of September 30, 2017, 67.6% of our cash and cash equivalents were held in China, and 48.9% were held by our VIEs and denominated in Renminbi. Although we consolidate the results of our VIEs and their subsidiaries, we only have access to the assets or earnings of our VIEs and their subsidiaries through our contractual arrangements with our VIEs and their shareholders. See "Corporate History and Structure—Contractual Arrangements with Our VIEs and Their Respective Shareholders." For restrictions and limitations on liquidity and capital resources as a result of our corporate structure, see "—Holding Company Structure."

In utilizing the proceeds we expect to receive from this offering, we may make additional capital contributions to our PRC subsidiaries, establish new PRC subsidiaries and make capital contributions to these new PRC subsidiaries, make loans to our PRC subsidiaries, or acquire offshore entities with operations in China in offshore transactions. However, most of these uses are subject to PRC regulations.

See "Risk Factors—Risks Related to Doing Business in China—PRC regulation of loans to, and direct investment in, PRC entities by offshore holding companies and governmental control of currency conversion may restrict or prevent us from using the proceeds of our initial public offering to make loans to our PRC subsidiaries and consolidated affiliated entities and their subsidiaries, or to make additional capital contributions to our PRC subsidiaries" and "Use of Proceeds."

A majority of our future revenues are likely to continue to be in the form of Renminbi. Under existing PRC foreign exchange regulations, Renminbi may be converted into foreign exchange for current account items, including profit distributions, interest payments and trade-and service-related foreign exchange transactions.

We expect that substantially all of our future revenues will be denominated in Renminbi. Under existing PRC foreign exchange regulations, payments of current account items, including profit distributions, interest payments and trade and service-related foreign exchange transactions, can be made in foreign currencies without prior SAFE approval as long as certain routine procedural requirements are fulfilled. Therefore, our PRC subsidiaries are allowed to pay dividends in foreign currencies to us without prior SAFE approval by following certain routine procedural requirements. However, approval from or registration with competent government authorities is required where the Renminbi is to be converted into foreign currency and remitted out of China to pay capital expenses such as the repayment of loans denominated in foreign currencies. The PRC government may at its discretion restrict access to foreign currencies for current account transactions in the future.

Net cash provided by operating activities for the nine months ended September 30, 2017 was RMB285.6 million (US$42.9 million), as compared to net loss of RMB132.4 million (US$19.9 million) in the same period. The difference was primarily due to an increase of RMB317.2 million (US$47.7 million) in deferred revenue and an increase of RMB218.1 million (US$32.8 million) in accounts payable, partially offset by an increase in prepayments and other current assets of RMB213.3 million (US$32.1 million) and an increase in accounts receivable of RMB244.7 million (US$36.8 million). The increases in deferred revenue, accounts payable, prepayments and other current assets and accounts receivable were attributable to our business expansion. The principal non-cash items affecting the difference between our net loss and our net cash provided by operating activities for the nine months ended September 30, 2017 were RMB194.4 million (US$29.2 million) in depreciation and amortization, RMB54.9 million (US$8.3 million) in share-based compensation expenses and RMB12.8 million (US$1.9 million) in impairment of long-term investments.

Net cash used in operating activities for the nine months ended September 30, 2016 was RMB222.6 million, as compared to net loss of RMB512.4 million in the same period.

The difference was also due to an increase of RMB78.2 million in accounts payable and an increase of 30.1 million in deferred revenue, partially offset by an increase of RMB41.1 million in accounts receivable and an increase of RMB34.7 million in prepayments and other current assets. The increases in accounts payable, deferred revenue, accounts receivable and prepayments and other current assets were attributable to our business expansion.

Net cash used in operating activities in 2016 was RMB199.0 million (US$29.9 million), as compared to net loss of RMB911.5 million (US$137.0 million) in the same period. The difference was primarily due to an increase of RMB194.6 million (US$29.3 million) in deferred revenue and an increase of RMB149.6 million (US$22.5 million) in accounts payable, partially offset by an increase in prepayments and other current assets of RMB125.4 million (US$18.8 million), an increase in accounts receivable of RMB92.6 million (US$13.9 million), and an increase in receivables from related parties of RMB5.0 million (US$0.8 million). The increases in deferred revenue, accounts payable, prepayments and other current assets and accounts receivable were attributable to the growth of our business. In particular, the increase in deferred revenue was attributable to growth in advanced payments from mobile game players. The principal non-cash items affecting the difference between our net loss and our net cash used in operating activities in 2016 were RMB365.5 million (US$54.9 million) in share-based compensation expenses, RMB161.5 million (US$24.3 million) in depreciation and amortization, and RMB21.3 million (US$3.2 million) in unrealized exchange losses.

Net cash used in 2015 was RMB191.9 million, as compared to net loss of RMB373.5 million in the same period.

The increases in accounts payable and prepayments and other current assets were attributable to the growth of our business. The increase in salary and welfare payables was attributable to increase in employee headcount. The principal non-cash items affecting the difference between our net loss and our net cash used in operating activities in 2015 were RMB100.9 million in share-based compensation expenses, RMB42.2 million in depreciation and amortization and RMB3.7 million in unrealized exchange losses.

Net cash used in investing activities for the nine months ended September 30, 2017 was RMB938.1 million (US$141.0 million), primarily due to purchase of short-term investments of RMB3,801.4 million (US$571.4 million), purchase of intangible assets of RMB320.7 million (US$48.2 million), purchase of property and equipment of RMB88.3 million(US$13.3 million), and cash paid on long-term investments of RMB182.9 million (US$27.5 million), partially offset by proceeds from maturities of short-term investments of RMB3,455.2 million (US$519.3 million).

We intend to fund our future capital expenditures with our existing cash balance and proceeds from this offering. We will continue to make capital expenditures to meet the expected growth of our business.

The following table sets forth our contractual obligations as of December 31, 2016:

Other than as shown above, we did not have any significant capital and other commitments, long-term obligations or guarantees as of December 31, 2016.

We have not entered into any financial guarantees or other commitments to guarantee the payment obligations of any third parties. In addition, we have not entered into any derivative contracts that are indexed to our shares and classified as shareholder's equity or that are not reflected in our consolidated financial statements. Furthermore, we do not have any retained or contingent interest in assets transferred to an unconsolidated entity that serves as credit, liquidity or market risk support to such entity. We do not have any variable interest in any unconsolidated entity that provides financing, liquidity, market risk or credit support to us or engages in leasing, hedging or product development services with us.

An accounting policy is considered critical if it requires an accounting estimate to be made based on assumptions about matters that are highly uncertain at the time such estimate is made, and if different accounting estimates that reasonably could have been used, or changes in the accounting estimates that are reasonably likely to occur periodically, could materially impact the consolidated financial statements.

We prepare our financial statements in conformity with U.S. GAAP, which requires us to make judgments, estimates and assumptions. We continually evaluate these estimates and assumptions based on the most recently available information, our own historical experiences and various other assumptions that we believe to be reasonable under the circumstances. Since the use of estimates is an integral component of the financial reporting process, actual results could differ from our expectations as a result of changes in our estimates. Some of our accounting policies require a higher degree of judgment than others in their application and require us to make significant accounting estimates.

The following descriptions of critical accounting policies, judgments and estimates should be read in conjunction with our consolidated financial statements and accompanying notes and other disclosures included in this prospectus. When reviewing our financial statements, you should consider (i) our selection of critical accounting policies, (ii) the judgments and other uncertainties affecting the application of such policies and (iii) the sensitivity of reported results to changes in conditions and assumptions.

Subsidiaries are those entities in which we, directly or indirectly, (i) control more than one half of the voting power, (ii) have the power to appoint or remove the majority of the members of the board of directors, or to cast a majority of votes at the meeting of board of directors, or (iii) have the power to govern the financial and operating policies under a statute or agreement among the shareholders or equity holders.

A consolidated variable interest entity is an entity in which we, or our subsidiaries, through contractual arrangements, have the power to direct the activities that most significant impact the entity's economic performance, bear the risks of and enjoy the rewards normally associated with ownership of the entity, and therefore are the primary beneficiary of.

We consolidate our subsidiaries and the variable interest entities of which we are the primary beneficiary. On a periodic basis, we reconsider the initial determination of whether a legal entity is a consolidated entity upon the occurrence of certain events listed in ASC 810-10-35-4. We also continually reconsider whether we are the primary beneficiary of our affiliated entities as facts and circumstances change.

We recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable and collectability is reasonably assured.

We primarily operate these games and generate revenues from the sale of in-game virtual items that enhance the game-playing experience.

In accordance with ASC 605-45, Revenue Recognition: Principal Agent Considerations, we evaluate agreements with the game developers, distribution channels and payment channels in order to determine whether or not we act as the principal or as an agent in the arrangement with each party, which we consider in determining if relevant revenues should be reported gross or net of the pre-determined amount of proceeds shared with the other party. Such determination of whether to record the revenues gross or net is based on an assessment of various factors, including but not limited to whether we (i) are the primary obligor in the arrangement, (ii) have general inventory risk, (iii) change the product or perform part of the services, (iv) have latitude in establishing the selling price, and (v) have involvement in the determination of product and service specifications.

We record revenue generated from exclusively distributed mobile games on a gross basis as we are acting as the principal to fulfill all obligations related to the mobile game operation. We act as the primary obligor, responsible for the launch of the game, hosting and maintenance of game servers and decide when and how to operate the in-game promotions. We also determine the pricing of in-game virtual items and make localized version for games licensed from overseas developers.

Proceeds earned from selling in-game virtual items are shared between us and the game developers, with the amount paid to the developers generally calculated based on amount paid by players, after deducting the fees paid to the payment channels and the distribution channels including the credit allowable for deduction, multiplied by a predetermined percentage for each game. Fees paid to game developers, distribution channels (app stores) and payment channels are recorded as cost of revenues.

For the purposes of determining when services have been provided to players, we determined that an implied obligation exists for us to provide on-going services to the players who purchased virtual items to gain an enhanced game-playing experience over an estimated average playing period of the paying players for each game. Accordingly, we recognize the revenues ratably over such estimated average playing period, starting from the point in time when virtual items are delivered to the players' accounts and all other revenue recognition criteria are met.

We consider the average period that players typically play the games and other player behavior patterns, as well as various other factors, to arrive at the best estimates for the playing period of the paying players for each game, usually from three to six months. To compute the estimated average playing period for paying users, we consider the initial purchase date as the starting point of a player's lifespan. We track populations of paying players who made their initial purchase during the 10-days interval period, which we refer to as cohorts, and track each cohort to understand the number of players from each cohort who played the game after the initial purchase. To determine the ending point of a paying user's lifespan beyond the date for which observable data are available, we extrapolate the actual observed attrition rate to arrive at an estimated weighted average playing lifespan for paying users of the selected games. If a new game is launched and only a limited period of paying player data are available, then we consider other qualitative factors, such as the behavior patterns for paying players of other games with similar characteristics and similar paying player behavior patterns, such as targeted players and purchasing frequency. While we believe our estimates to be reasonable based on

available game player information, we may revise such estimates based on new information indicating a change in the game player behavior patterns. Any such adjustments are applied prospectively.

We also offer publishing services for mobile games developed by third-party game developers. For such games, we act as a distribution channel, and publish the games on our own app or websites. In other words, we provide a game portal through which game players can download the mobile games to their mobile devices and we earn game promotion service revenue.

With respect to the jointly operated license arrangements between us and the game developers, we considered the factors that (i) the developers are responsible for providing the game products desired by them; (ii) the developers have the responsibility of hosting and maintenance of game servers for running the games; and (iii) the developers have the right to change the pricing of in-game virtual items. Our responsibilities are publishing, providing payment solution and market promotion service. Therefore, we view the game developers as our customers and considers us as the agent of the game developers in these arrangements. Accordingly, we record the game publishing service revenue from these games net of amounts paid to the game developers.

We derive our advertising revenues principally from short-term online advertising contracts. Advertising service contracts may consist of multiple elements with a typical term of less than three months. Such elements generally represent different formats of advertisement, including but not limited to banners, text-links, videos, logos, buttons and rich media. Each element is time-based and the service period of the element is usually within three months. In accordance with ASU 2009-13, Revenue Recognition: Multiple Deliverable Revenue Arrangements, we treat advertising contracts with multiple deliverable elements as separate units of accounting for revenue recognition purposes and recognize revenue over the advertising period in the contract when each deliverable element of advertisements is provided and all the other revenue recognition criteria are met. Since the contract price is for all deliverables, we allocate the arrangement consideration to all deliverables at the inception of the arrangement on the basis of their relative selling price according to the selling price hierarchy established by ASU 2009-13. We use (a) vendor-specific objective evidence of selling price, if it exists, or otherwise (b) third-party evidence of selling price. If neither (a) nor (b) exists, we use (c) the management's best estimate of the selling price for that deliverable. As the deliverables are not sold separately, the best estimate of the selling price has taken into consideration of (i) the pricing of advertising areas of our platform with similar popularities, (ii) advertisements with similar formats, and (iii) quoted prices from competitors and other market conditions.

We provide cash incentives in the form of sales rebate to certain advertising agencies, and account for such incentives as a reduction of revenue. We have estimated and recorded the rebates based on historical transactions and the rebate rate with certain advertising agencies.

Users can purchase the virtual currency on our platform named "B-coin" via debit and credit cards or through bank transfers via online payment systems provided by third-party payment systems. "B-coin" can be used to purchase virtual items of live broadcasting and other valued-added services. Proceeds received from the sales of "B-coin" to users but not yet consumed are recorded as deferred revenues. Revenue is recognized upon conversion or consumption, and is recognized according to the respective prescribed revenue recognition policies discussed below.

We operate and maintain live broadcasting channels whereby users can enjoy live performances provided by hosts and interact with hosts. Most of the hosts host the performance on their own. We

create and sell virtual items to users so that the users present them simultaneously to hosts to show their support. The virtual items sold by us comprise of either consumable items or time-based items. Under arrangements with hosts, we share with them a portion of the revenues derived from the sales of virtual items. Revenues derived from the sale of virtual items are recorded on a gross basis as we act as the principal to fulfill all obligations related to the sale of virtual items. Accordingly, revenue is recognized when the virtual item is delivered and consumed, in the case of consumable item, or, recognized ratably over the period each virtual item is made available to the user, which does not exceed one year, in the case of time-based item. The portion paid to hosts is recognized as cost of revenues. The other VAS include sales of virtual items for video content and membership subscription. Revenues from sales of virtual items are recognized on item basis, which is consistent with the revenue recognition approach for live broadcasting. Revenues from membership subscription are recognized ratably over the period of subscription when services are rendered.

Other revenues consist of other fee-based premium services, which are mainly from the sales of products through our e-commerce platform, as well as revenues from holding certain offline performance activities. We evaluate whether it is appropriate to record the net amount earned as commissions or the gross amount of product sales. When we are not the primary obligor, do not bear the inventory risk and do not have the ability to establish the price, revenues are recorded on a net basis. Otherwise revenues are recorded on a gross basis. Discount coupons for the customers to use in purchases are treated as a reduction of revenue when the related transaction is recognized.

We estimate revenue of mobile game, live broadcasting and other valued added service from third-party payment processors in the current period when reasonable estimates of these amounts can be made. The processors provide reliable interim preliminary reporting within a reasonable time following the end of each month and we maintains records of sales data, both of which allow us to make reasonable estimates of revenue and therefore recognize revenue during the reporting period. Determination of the appropriate amount of revenue recognized involves judgments and estimates that we believe are reasonable, but actual results may differ from our estimates. When we receive the final reports, to the extent not received within a reasonable time frame following the end of each month, we record any differences between estimated revenue and actual revenue in the reporting period when we determine the actual amounts. The revenue on the final revenue report has not differed materially from the reported revenue for the periods presented.

Share-based compensation expenses arise from share-based awards, including share options for the purchase of ordinary shares. We account for share-based awards granted to employees in accordance with ASC 718 Stock Compensation and share-based awards granted to non-employees in accordance with ASC 505. For share options for the purchase of ordinary shares granted to employees classified as equity awards, the related share-based compensation expenses are recognized in the consolidated financial statements based on the fair value of the awards on the grant date, which is calculated using the binomial option pricing model. The determination of the fair value is affected by the share price as well as assumptions regarding a number of complex and subjective variables, including the expected share price volatility, actual and projected employee share option exercise behavior, risk-free interest rates and expected dividends. The fair value of the ordinary shares is assessed using the income approach/discounted cash flow method, with a discount for lack of marketability, given that the shares underlying the awards were not publicly traded at the time of grant. Share-based compensation expenses are recorded net of estimated forfeitures using straight-line method in accordance with the

service period requirement, such that expenses are recorded only for those share-based awards that are expected to ultimately vest.

For share options granted with service condition and the occurrence of an initial public offering as performance condition, cumulative share-based compensation expenses for the options that have satisfied the service condition will be recorded upon the completion of the initial public offering.

Share-based compensation expenses for share options granted to non-employees are measured at fair value at the earlier of the performance commitment date or the date service is completed, and recognized over the period during which the service is provided. We apply the guidance in ASC 505-50 to measure share options granted to non-employees based on the then-current fair value at each reporting date.

We are a private company with no quoted market prices for our ordinary shares. We therefore need to make estimates of the fair value of our ordinary shares at various dates in order to determine the fair value of our ordinary shares at the date of the grant of a share-based compensation award to our employees. Estimates will not be necessary to determine the fair value of new awards once the American depositary shares underlying our ordinary shares begin trading.

The following table sets forth the fair value of our ordinary shares estimated taking into account independent valuations advice:


Date	Fair Value Per Share (US$)		DLOM	Discount Rate		Type of Valuation
November 3, 2014	$	0.18		22	%		32.0	%	Retrospective
July 15, 2015	$	1.94		21	%		23.0	%	Retrospective
January 1, 2016	$	1.94		19	%		22.5	%	Retrospective
March 31, 2016	$	2.12		19	%		22.0	%	Retrospective
May 10, 2016	$	2.69		19	%		20.5	%	Retrospective
October 1, 2016	$	2.74		18	%		20.0	%	Retrospective
January 1, 2017	$	2.80		17	%		20.0	%	Retrospective
April 1, 2017	$	3.84		16	%		19.0	%	Retrospective
June 30, 2017	$	4.32		12	%		19.0	%	Retrospective
September 30, 2017	$	5.72		10	%		18.0	%	Retrospective

The option-pricing method was used to allocate equity value of our company to preferred and ordinary shares, taking into account the guidance prescribed by the AICPA Audit and Accounting Practice Aid. This method requires making estimates of the anticipated timing of a potential liquidity event, such as a sale of our company or an initial public offering, and estimates of the volatility of our equity securities. The anticipated timing is based on the plans of our board and management.

The other major assumptions used in calculating the fair value of ordinary shares include:

The determined fair value of our ordinary shares increased from US$0.18 per share as of November 3, 2014 to $1.94 per share as of July 15, 2015. We believe the increase in the fair value of our ordinary shares was primarily attributable to the following factors:

The determined fair value of our ordinary shares increased from US$1.94 per share as of July 15, 2015 to US$2.12 per share as of March 31, 2016 and further to US$2.69 per share as of May 10, 2016. We believe the increase in the fair value of our ordinary shares was primarily attributable to the following factors:

The determined fair value of our ordinary shares increased from US$2.69 per share as of May 10, 2016 to US$2.80 per share as of January 1, 2017 and further to US$3.84 per share as of April 1, 2017.

We believe the increase in the fair value of our ordinary shares was primarily attributable to the following factors:

The determined fair value of our ordinary shares increased from US$3.84 per share as of April 1, 2017 to US$4.32 per share as of June 30, 2017 and further to US$5.72 per share as of September 30, 2017. We believe the increase in the fair value of our ordinary shares was primarily attributable to the following factors:

Current income taxes are provided on the basis of income/(loss) for financial reporting purposes, adjusted for income and expense items which are not assessable or deductible for income tax purposes, in accordance with the regulations of the relevant tax jurisdictions. Deferred income taxes are provided using the liability method. Under this method, deferred income taxes are recognized for the tax consequences of temporary differences by applying enacted statutory rates applicable to future years to differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities. The tax base of an asset or liability is the amount attributed to that asset or liability for tax purposes. The effect on deferred taxes of a change in tax rates is recognized in the consolidated statement of operations and comprehensive loss in the period of change. A valuation allowance is provided to reduce the amount of deferred tax assets if it is considered more likely than not that some portion of, or all of the deferred tax assets will not be realized.

In order to assess uncertain tax positions, we apply a "more likely than not" threshold and a two-step approach for tax position measurement and financial statement recognition. Under the two-step approach, the first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. We

recognize interest and penalties, if any, under accrued expenses and other current liabilities on its consolidated balance sheet and under other expenses in its consolidated statement of operations and comprehensive loss. We did not have any significant unrecognized uncertain tax positions as of and for the years ended December 31, 2015 and 2016.

The licensed copyrights of video content are recorded in "Intangible assets, net", at the lower of amortized cost or net realizable value. In accordance with ASC Topic 920, Entertainment-Broadcasters, costs incurred in purchasing copyrights of video content are capitalized and amortized over the shorter of the license period and the projected useful life of the video content. Any licensed copyrights that do not meet the criteria are included in the commitments disclosure. We amortize the costs incurred in purchasing licensed copyrights in "Cost of revenues" on a straight line basis. If expectations of the usefulness of a video content are revised downward, the unamortized cost is written down to the estimated net realizable value. A write-down from unamortized cost to a lower estimated net realizable value establishes a new cost basis.

Prior to this offering, we have been a private company with limited accounting personnel and other resources with which we address our internal control over financial reporting. In connection with the audits of our consolidated financial statements as of and for the years ended December 31, 2015 and 2016, we and our independent registered public accounting firm identified one material weakness in our internal control over financial reporting. As defined in the standards established by the U.S. Public Company Accounting Oversight Board, a "material weakness" is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements will not be prevented or detected on a timely basis.

We have implemented and plan to implement a number of measures to address the material weakness that has been identified in connection with the audits of our consolidated financial statements as of and for the years ended December 31, 2015 and 2016. We have hired additional qualified financial and accounting staff with working experience of U.S. GAAP and SEC reporting requirements. We have also established clear roles and responsibilities for accounting and financial reporting staff to address complex accounting and financial reporting issues. Furthermore, we will continue to further expedite and streamline our reporting process and develop our compliance process, including establishing a comprehensive policy and procedure manual, to allow early detection, prevention and resolution of potential compliance issues, and establishing an ongoing program to provide sufficient and appropriate training for financial reporting and accounting personnel, especially training related to U.S. GAAP and SEC reporting requirements. We intend to conduct regular and continuous U.S. GAAP accounting and financial reporting programs and send our financial staff to attend external U.S. GAAP training courses. We also intend to hire additional resources to strengthen the financial reporting function and set up a financial and system control framework. However, we cannot assure

you that all these measures will be sufficient to remediate our material weakness in time, or at all. See "Risk Factors—Risks Related to Our Business and Industry—If we fail to implement and maintain an effective system of internal controls to remediate our material weakness over financial reporting, we may be unable to accurately report our results of operations, meet our reporting obligations or prevent fraud, and investor confidence and the market price of our ADSs may be materially and adversely affected."

As a company with less than US$1.07 billion in revenue for our last fiscal year, we qualify as an "emerging growth company" pursuant to the JOBS Act. An emerging growth company may take advantage of specified reduced reporting and other requirements that are otherwise applicable generally to public companies. These provisions include exemption from the auditor attestation requirement under Section 404 of the Sarbanes-Oxley Act of 2002 in the assessment of the emerging growth company's internal control over financial reporting.

Bilibili Inc. is a holding company with no material operations of its own. We conduct our operations primarily through our PRC subsidiaries, our VIEs and their subsidiaries in China. As a result, Bilibili Inc.'s ability to pay dividends depends upon dividends paid by our PRC subsidiaries. If our existing PRC subsidiaries or any newly formed ones incur debt on their own behalf in the future, the instruments governing their debt may restrict their ability to pay dividends to us. In addition, our wholly foreign-owned subsidiaries in China are permitted to pay dividends to us only out of its retained earnings, if any, as determined in accordance with PRC accounting standards and regulations. Under PRC law, each of our subsidiaries and our VIEs in China is required to set aside at least 10% of its after-tax profits each year, if any, to fund certain statutory reserve funds until such reserve funds reach 50% of their registered capital. In addition, our wholly foreign-owned subsidiaries in China may allocate a portion of their after-tax profits based on PRC accounting standards to enterprise expansion funds and staff bonus and welfare funds at their discretion, and our VIEs may allocate a portion of its after-tax profits based on PRC accounting standards to a surplus fund at their discretion. The statutory reserve funds and the discretionary funds are not distributable as cash dividends. Remittance of dividends by a wholly foreign-owned company out of China is subject to examination by the banks designated by SAFE. Our PRC subsidiaries have not paid dividends and will not be able to pay dividends until they generate accumulated profits and meet the requirements for statutory reserve funds.

To date, inflation in China has not materially affected our results of operations. According to the National Bureau of Statistics of China, the year-over-year percent changes in the consumer price index for December 2015, 2016 and 2017 were increases of 1.6%, 2.1% and 1.6%, respectively. Although we have not been materially affected by inflation in the past, we may be affected if China experiences higher rates of inflation in the future.

Substantially all of our revenues and expenses are denominated in RMB. We do not believe that we currently have any significant direct foreign exchange risk and have not used any derivative financial instruments to hedge exposure to such risk. Although our exposure to foreign exchange risks should be limited in general, the value of your investment in our ADSs will be affected by the exchange rate between U.S. dollar and Renminbi because the value of our business is effectively denominated in RMB, while our ADSs will be traded in U.S. dollars.

The value of Renminbi against the U.S. dollar and other currencies may fluctuate and is affected by, among other things, changes in political and economic conditions and the foreign exchange policy adopted by the PRC government. On July 21, 2005, the PRC government changed its policy of pegging the value of the Renminbi to the U.S. dollar. Following the removal of the U.S. dollar peg, the Renminbi appreciated more than 20% against the U.S. dollar over the following three years. Between July 2008 and June 2010, this appreciation halted and the exchange rate between the Renminbi and the U.S. dollar remained within a narrow band. Since June 2010, the PRC government has allowed the Renminbi to appreciate slowly against the U.S. dollar again, and it has appreciated more than 10% since June 2010. On August 11, 2015, the People's Bank of China announced plans to improve the central parity rate of the Renminbi against the U.S. dollar by authorizing market-makers to provide parity to the China Foreign Exchange Trading Center operated by the People's Bank of China with reference to the interbank foreign exchange market closing rate of the previous day, the supply and demand for foreign currencies as well as changes in exchange rates of major international currencies. Effective from October 1, 2016, the International Monetary Fund added Renminbi to its Special Drawing Rights currency basket. Such change and additional future changes may increase volatility in the trading value of the Renminbi against foreign currencies. The PRC government may adopt further reforms of its exchange rate system, including making the Renminbi freely convertible in the future. Accordingly, it is difficult to predict how market forces or PRC or U.S. government policy may impact the exchange rate between Renminbi and the U.S. dollar in the future.

To the extent that we need to convert U.S. dollars into Renminbi for our operations, appreciation of Renminbi against the U.S. dollar would reduce the Renminbi amount we receive from the conversion. Conversely, if we decide to convert Renminbi into U.S. dollars for the purpose of making payments for dividends on our ordinary shares or ADSs, servicing our outstanding debt, or for other business purposes, appreciation of the U.S. dollar against the Renminbi would reduce the U.S. dollar amounts available to us.

As of September 30, 2017, we had Renminbi-denominated cash and cash equivalents of RMB207.7 million. A 10% depreciation of Renminbi against the U.S. dollar based on the foreign exchange rate on September 30, 2017 would result in a decrease of US$2.8 million in cash and cash equivalents. A 10% appreciation of Renminbi against the U.S. dollar based on the foreign exchange rate on September 30, 2017 would result in an increase of US$3.5 million in cash and cash equivalents.

Our exposure to interest rate risk primarily relates to the interest income generated by excess cash, which is mostly held in interest-bearing bank deposits. Interest-earning instruments carry a degree of interest rate risk. We have not been exposed to material risks due to changes in interest rates, and we have not used any derivative financial instruments to manage our interest risk exposure. However, our future interest income may fall short of expectations due to changes in market interest rates.

A list of recently issued accounting pronouncements that are relevant to us is included in note 2(cc) to our consolidated financial statements included elsewhere in this prospectus.

Online entertainment is a large and fast growing industry in China. According to the iResearch Report, China's online entertainment industry market reached RMB205.8 billion in 2016 and is expected to grow at a CAGR of 29.6% to RMB752.7 billion in 2021. In particular, Generation Z, the demographic cohort in China of individuals born from 1990 to 2009, is the key driving force of the evolution of China's online entertainment industry. According to the iResearch Report, the population of Generation Z has reached 328 million in 2016. Their market share contribution to the online entertainment industry in China in terms of dollar spending is expected to grow from 45.8% in 2014, to 54.8% in 2017 and further to 62.1% in 2020.

Generation Z have grown up in a unique socio-environment that enable them to think, behave and value differently from the previous generations in China, as mainly demonstrated in the following respects.

Consumption upgrades to address cultural needs. Generation Z have grown up in an era of rapid economic growth in China and therefore raised in better-educated and wealthier households compared to previous generations. With improved living standards and better education, Generation Z are more exposed to cultural products from all over the world and have the ability to appreciate their value. Therefore, they are also willing to spend on cultural needs in addition to material needs, and tend to have the discretionary income to do so.

Deep internet adoption in daily lives. Growing up in the internet boom, Generation Z are native internet users. They are used to using internet for nearly every aspects of their lives, including information acquisition, socialization, recreation and entertainment. According to the iResearch Report, 284 million of Generation Z are internet users, implying an internet penetration rate of 86.7%, which is far above the national average rate of 55.8%.

Strong desire for self-expression. Many of Generation Z are the only child of their families, and they look to build self-image, establish personal views and express original creative ideas. They tend to

be especially active in interest-based communities, where they can find opportunities of self-expression, which in turn stimulate cultural consumption.

Online entertainment powered by mobile internet and technology, diversified content and interactive features has become the mainstream media format, as traditional media outlets, which provide content covering limited themes and subjects through a simplex "one-way" form, can no longer satisfy the evolving entertainment needs. China's online entertainment industry, comprised of verticals such as video, game, live broadcasting, music and literature, has been expanding rapidly to meet the increasing demand of Generation Z for quality content. Such content covers a wide variety of themes, including anime and comics, game, music, fashion, lifestyle, technology, movie and television serial drama, and will continue to diversify and grow.

Content is the core of the online entertainment industry, and users drive the growth of this industry. Quality content attracts and retains users, which in turn incentivize content providers to create more engaging content. This virtuous cycle propels the healthy development of the online entertainment industry. According to the iResearch Report, as of the end of 2016, there were 636 million online entertainment consumers in China, who on average spent 1.4 hours every day on online entertainment. Among them, 282 million were Generation Z, and they on average spent more than 1.6 hours every day on online entertainment.

A large number of Generation Z are actively involved in content generation and promotion, rather than passive content viewing and consumption. Their increasing content consumption and participation in the online entertainment industry are mainly demonstrated in the following respects.

More content generation. Generation Z tend to have a strong and evolving desire to express themselves and showcase their talents by creating content. They are an emerging group of creators of content.

More interaction through content. As online interaction become more frequent, internet users, especially Generation Z, have increasing demand to look for socialization in addition to entertainment on entertainment platforms. Open online entertainment platforms allow users to socialize and exchange opinions with content providers and other audiences through sharing, commenting and features such as "liking". User interactions have become more frequent and diversified, which have enhanced the breadth and depth of content offered.

Stronger "fans effect". A large portion of Generation Z are teenagers who are developing their cultural tastes and more likely to be influenced by trends. Therefore, peer-driven or social-driven decision has a significant impact on Generation Z's entertainment consumption choices. This generation has demonstrated strong attachment and loyalty to specific brands and content. Among them, there are many hardcore fans of idols, opinion leaders and advocates, copyrighted works and their adaptations, as well as platforms. The strong "fan effect" further substantiates the virtuous interaction between content and users.

Driven by the increasing demand on a diverse range of entertainment content, key sectors of the online entertainment industry, including video, games and live broadcasting, have been growing exponentially. However, currently few one-stop platforms in China can fulfill users' demands at once and users typically visit different online platforms for specific entertainment purposes. Platforms offering full-spectrum multi-media content tend to resonate well with users and are better positioned to capture the significant growth potential of China's online entertainment industry.

China's online video market reached RMB62.1 billion in 2016 and is expected to reach RMB224.9 billion in 2021, representing a CAGR of 29.3%, according to the iResearch Report. Online video platforms in China typically include the service providers that host and store video content and enable users to upload and view video content online, and do not include the service providers that operate solely in the online video search or aggregation domain. Generation Z's contribution to this market is also expected to grow from 35.2% in 2014 to 46.5% in 2017 and further to 66.6% in 2020, according to the iResearch Report. PUG video market has been exceptionally popular among Generation Z due to its user-creation origin and the positive interaction among users. Therefore, this market has been the key growing portion of online video market.

Online video platforms in China mainly monetize through online advertising. As more users are willing to pay for premium content and services, those platforms are also starting to generate revenues through membership or content fees.

Online advertising. Content platforms are attractive to advertisers because of the valuable high-quality and stable user traffic generation. Online advertising has therefore become a key revenue stream for content platforms. According to the iResearch Report, China's online video advertising market reached RMB30.6 billion in 2016 and is expected to grow to RMB112.0 billion in 2021, representing a CAGR of 29.6%. As online entertainment platforms by nature are suitable for content generation and display, advertising format on these platforms can be diversified, from traditional display advertisements to those well integrated into the native content of the hosting platforms.

Paid content services. Content platforms can generate revenues through paid content services where users pay a membership fee to access premium content for a fixed time period or pay for specific content without becoming a member of such platform. Generation Z have grown up during the high growth period of the entertainment industry in China. They are able to recognize the value of quality content, which contributes to their willingness to pay for it. They are also more accustomed to pay for content and premium services as they grow up, compared to previous generations.

With the rapid development of mobile technology and users' growing demand to utilize fragmented time, mobile games have achieved higher growth than client-based games and web-based online games. According to the iResearch Report, China's mobile games market reached RMB102.3 billion in 2016, and is expected to further grow at a CAGR of 24.4% to RMB304.5 billion in 2021. Generation Z's contribution to this market is also expected to grow from 56.0% in 2014 to 63.8% in 2017 and further to 65.7% in 2020, according to the iResearch Report. Generation Z users on average spend 0.9 hours on mobile games every day.

The market of mobile games with anime and comics themes, such as Onmyoji, Fate/Grand Order and Honkai Impact series, emerged in China in 2014 and has significantly outgrown the overall mobile games market, driven by the strong demand from a large Generation Z user base. According to the iResearch Report, it reached RMB6.8 billion in 2016, and is expected to reach RMB37.5 billion by 2021, representing a CAGR of 40.8% from 2016 to 2021. In China, the number of players for anime and comics themed mobile games was 42 million as of 2016, and is expected to increase to 62 million in 2017, approximately 68.9% of whom are Generation Z, according to the iResearch Report. More

than 80.0% of Generation Z players for anime and comics themed mobile games have paid for games, according to the iResearch Report.

In-game sale of virtual items is the key monetization model for online games, especially for mobile games. There are various in-game virtual items for players, which can either be functional to help players upgrade or advance in games, or decorative, such as different skins and styles, or even collectable, such as rare or limited edition items, to fulfill players' different demands.

In China, live broadcasting started in the form of showroom broadcasting in 2008 and has gradually built up its user and market scale since then. According to the iResearch Report, China's live broadcasting market reached RMB23.3 billion in 2016, with 344 million users, and is expected to expand to RMB113.7 billion in 2021, representing a CAGR of 37.4%. Generation Z's contribution to

this market is also expected to grow from 22.2% in 2014 to 37.7% in 2017 and further to 45.5% in 2020, according to the iResearch Report.

The live broadcasting market has seen intensified competition and increasingly homogenized content. In this context, user-centered platforms focusing on user generated content have generally outperformed its competitors and gained market share as they are able to utilize their large base of user generated content and bring differentiated content to users.

Payment by audience is the main monetization model for online live broadcasting. Users can participate in live broadcasting through purchasing virtual items and gifting them to broadcasting hosts to demonstrate their appreciation or interact with those hosts. Platforms typically take a percentage of the payment as commission.

Overall, China's online entertainment market is massive and expected to grow at high speed. As Generation Z is core to future growth, catering to their demand for diversified and interactive content via one-stop platforms is essential to outperform in the competitive market. As licensed content acquisition costs continue to go up under heated competition, platforms where users natively generate high-quality PUGC have a competitive edge.

We represent the iconic brand of online entertainment for the young generations in China. We provide high-quality content and an immersive entertainment experience, and have built our platform based on the strong emotional connections of our users to our content and communities. We started as a content community inspired by ACG, and have evolved into a full-spectrum online entertainment world covering a wide array of genres and media formats, including videos, live broadcasting and mobile games. We have now become the welcoming home of diverse cultures and interests and destination for discovering cultural trends and phenomena for young generations in China. We rank No.1 in terms of monthly average time spent per device and monthly average visits per device among online video platforms, an integral part of online entertainment in China, on an monthly aggregate basis in 2017, according to QuestMobile. We believe China will become the world's largest online entertainment market in the future and our brand recognition and market leadership among the young generations in China position us well to capture the significant opportunities.

Our vibrant communities fuel the ever-growing supply of creative PUGC. We have developed a robust system and nurtured an encouraging community culture that respects and rewards content creators and motivates the creation of inspirational content.

We focus on offering content that caters to the evolving and diversified interests of our users and our communities.

RMB1,734.7 million (US$260.7 million) for the same period of 2017. We incurred net loss of RMB373.5 million (US$56.1 million) in 2015 and RMB911.5 million (US$137.0 million) in 2016. For the nine months ended September 30, 2017, we had net loss of RMB132.4 million (US$19.9 million), compared to net loss of RMB512.4 million (US$77.0 million) for the same period of 2016.

We believe that the following competitive strengths contribute to our success and differentiate us from our competitors:

We represent the iconic brand for online entertainment serving the young generations in China. We focus on high-quality content and immersive entertainment experience, and have built our platform based on the strong emotional connection of our users to our content and communities. Our "bilibili" brand elicits highly favorable sentiments among users. We were ranked as the top searched keyword among people born in the 2000s according to Baidu Search Index of 2016. We believe China will become world's largest addressable market for entertainment consumption with significant headroom for growth. We rank No.1 in terms of monthly average time spent per device and monthly average visits per device among online video platforms in China on a monthly aggregate basis in 2017, according to QuestMobile. In December 2017, the monthly average time spent per device by our users was 539.3 minutes and the number of monthly average visits per device of our users was 66.0 times, based on the same source. We believe our brand recognition and prominent leadership among the young generations in China will empower us to capture the significant growth potential presented by this market.

We started as an ACG-inspired content community and have grown to be a full spectrum online entertainment world to meet our users' evolving entertainment needs. Our online platform covers 21 genres and a wide array of media formats. We serve cultural advocates of various interests, and empower them to discover, share, consume and create high-quality content.

As a result, we have become the welcoming home of diverse cultures and interests and destination for discovering cultural trends and phenomena for young generations in China.

We have developed a young and culturally aspirational user base willing to invest in high-quality entertainment content. According to QuestMobile, as of December 31, 2017, approximately 81.7% of our users were Generation Z. They typically receive quality education and are technology savvy, with strong demand for cultural products and avenues for self-expression and social interaction. A large number of Generation Z are actively involved in content creation and promotion, as well as socialization through content. We believe our users will become the driving force and trend-setters of entertainment consumption in China as they grow with our platform.

Strong demand for quality entertainment content has fueled the rapid expansion of our user base. In the fourth quarter of 2017, we had 71.8 million monthly active users, representing 45.3% growth over the same period of 2016. Driven by our aspirational and fast growing user base, across our platform, daily number of video views averaged 210.8 million in the fourth quarter of 2017, as compared to 80.2 million in the same period of 2016.

We capture the hearts and minds of our users with superior content experience, and offer a wide array of carefully designed interactive features such as commentaries, favorites and virtual gifting to

drive user engagement and loyalty. Our "bullet chatting" feature has embedded a robust social networking component and fostered a highly interactive and enjoyable viewing experience. In 2017, we had an average of 15.2 million monthly active users who participated in social interactions, generating a total of 221.1 million interactions on a monthly basis, as compared to 8.4 million and 113.5 million in 2016. These interactive features allow our users to resonate with other users of similar aspirations and interests, and therefore spend more time and remain active on our platform. In 2017, the average daily time spent per active user on our mobile app was approximately 76.3 minutes, as compared to 72.2 minutes in 2016.

We have pioneered an examination system to distinguish hardcore users and offer privileged identity as official members and more interactive features to them. As of December 31, 2017, we had 31.6 million official members who passed our membership exam, as compared to 21.9 million as of December 31, 2016. Our membership examination system has fostered a strong sense of belonging and ownership among our users. As a result, our official members have demonstrated even more engagement and loyalty. In the fourth quarter of 2017, 75.0% of monthly active official members participated in social interactions. For official members who visited our platform in each month of 2016, our 12th-month retention rate was above 79.0%.

Our diversified content offerings comprise PUG videos, licensed videos, live broadcasting, short video clips and mobile games. Our full spectrum, multi-media content ecosystem enables us to become a one-stop entertainment platform, and allows our users to fully showcase their talent.

Inspired and motivated by the encouraging community culture, our users frequently upload quality content to our platform, building a massive and ever-growing PUG video library, which is a strong value proposition to our users and critical to our thriving content ecosystem. In 2017, we had approximately 204,100 average monthly active content creators, compared to approximately 100,200 in 2016, and received an average of approximately 835,900 monthly video submissions in 2017, compared to approximately 358,100 in 2016. In 2017, PUG video views accounted for 85.5% of our total video views, as compared to 74.5% in 2016.

We systematically encourage and embrace a constructive community culture that conveys the utmost respect for content creators and the high-quality content they provide. The users contribute commentaries and closely follow their favorite content creators to show strong support. As of December 31, 2017, the number of content creators with more than 10,000 followers had more than doubled since December 31, 2016. The vibrant community culture fuels quality content creation, motivating content creators to create inspirational content and pioneer new genres to cater to the evolving and diversified interests of our user base.

We attract our users with engaging content, retain users with our vibrant communities, and curate the right content to satisfy our users' consumption needs. We have successfully created an ecosystem comprised of users, content creators, as well as third-party partners including licensed content providers, game operators, advertisers, and e-commerce partners. All ecosystem participants are motivated and rewarded in a sustainable way. The virtuous cycle formed by highly-engaged users, talented content creators and business partners lends itself well for monetization. As a result, we are able to derive revenue through adjacent offerings without diluting the quality of our user experience.

By offering content most compatible with our communities and user preference, we have attracted and retained an active and engaged user base who are loyal to our "bilibili" brand. Through their activities on our platform, we are able to deepen our understanding of our users through analyzing their interests and behaviors, and can curate the right content to continually satisfy their evolving

entertainment needs. This full-spectrum, multi-media content ecosystem provides us with multiple avenues for growth and monetization opportunities. Initially, we mainly monetize through mobile games by selling virtual items through in-app purchases. In 2017, our monthly active users for mobile games were 9.1 million, as compared to 3.1 million in 2016. We have recently started to monetize through advertising and live broadcasting as well. Across our platform, the number of our average monthly paying users in the fourth quarter of 2017 was approximately 1.1 million, an increase of 60.0% from the same period in 2016.

We benefit from the vision and experience of our senior management team. Our chairman and chief executive officer, Mr. Rui Chen, is a serial entrepreneur and has more than 15 years of experience in the internet and technology-related industries in China. He co-founded Cheetah Mobile (NYSE: CMCM) and served in senior management capacity at Kingsoft (HK: 3888), before he led the pioneering innovation in our company. The rest of our senior management team are all industry experts joining from leading internet companies in China, with extensive expertise across technology, product design, operations, and financial management.

Our management team brings with them passion and conviction for the growth prospects of China's online content consumption. They are cultural advocates themselves. As peers, they understand Generation Z's passion and interests. Their insights into young generation's content needs have helped guide our business expansion in the rapidly changing entertainment industry. The user-centric corporate culture they adhere to has helped reinforce our market leadership and brand recognition among our users.

We intend to achieve our mission and further solidify our unique position by pursuing the following strategies:

We strive to systematically enhance the content offerings on our platform, and we believe incentivizing and supporting content creators is crucial to this strategy. We will increase our initiatives and allocate more resources to enable content creators to thrive in our communities. For example, we plan to make more tools and features available to them to improve the process of content creation. Furthermore, we intend to expand and enhance the avenues through which content creators can realize the commercial potential of their works, which will incentivize content creators and in turn enhance our content offerings. We also intend to broaden the variety of content themes and media formats on our platform. We believe this strategy will lead to enhanced user retention and user base expansion.

We seek to improve multiple aspects of user experience on our platform, from content discovery, content-based interaction to content consumption, which we believe will lead to stronger user engagement and community resonance. The scale and engagement of our user base enable us to accumulate a massive volume of user data on our platform. We plan to further leverage our machine-based data analytic capabilities to develop deeper insights into user behavior and preference to personalize content feed to our users and improve user experience. Moreover, our users are young, energetic and dynamic, with evolving interests and inspiration. We will cater to their emerging needs and expand suitable content genres and media formats, which could in turn cultivate new cultures among young generations.

Our leading technologies are important pillars to our rapid growth, strengthening our user engagement, monetization capabilities and cost management. We will continue to invest in and develop our technologies, particularly artificial intelligence, big data analytics and cloud technology. We will enhance our recommendations feed and native search access to rich content by leveraging artificial intelligence technology, which will enhance user engagement. We will continue to strengthen our big data analytics capability of the rich user footprint and behavior on our platform, and improve our monetization capabilities. We will manage our bandwidth cost through improvement in cloud technology. We intend to make additional investments in our infrastructure to support the growth in our user base and traffic. We also plan to attract, train and retain more talent for these purposes.

We generate revenue mostly through mobile games, live broadcasting and advertising, and we plan to strengthen our monetization capabilities for all three categories. We will continue to work with game developers to source, localize and distribute high-quality mobile games that appeal to our users. In addition, we plan to expand our live broadcasting business by promoting closer interaction between hosts and users, adopting creative ways for virtual gifting, and enabling hosts to integrate relevant advertisements or promote merchandise during broadcasting. Furthermore, we plan to develop our performance-based advertisement system and work closely with advertisers on native advertising content, targeting the audience in our communities while minimizing disturbance to user experience.

We have built an extensive user base for our platform. According to QuestMobile, as of December 31, 2017, approximately 81.7% of our users were Generation Z. They typically receive quality education and are technology savvy, with strong demand for culture products and platform for self-expression and social interaction.

We started as an ACG-inspired content community and have grown into a full-spectrum online entertainment platform by empowering users to create, discover and share quality content, attracting new users with diverse interests and background, and adding new channels and sub-channels to our platform. As a result, we have become a welcoming home of diverse cultures and interests and the go-to destination for the followers of these cultures and interests.

Any user who visits our platform can watch or search content, and then he or she must register to activate the basic interactive features on our platform, such as liking videos and following content creators. Additional interactive features, such as bullet chatting and commenting, will become available to registered users once they become our "official members" by passing our multiple-choice membership exam consisting of 100 questions.

Our users have demonstrated high level of engagement on our platform. In the fourth quarter of 2017, we had an average of 71.8 million MAUs, as compared to 49.4 million for the same period in 2016. In 2017, the average daily time spent per active user on our mobile app was approximately 76.3 minutes, as compared to 72.2 minutes in 2016. Our official members are even more engaged. As of December 31, 2017, we had over 31.6 million official members, as compared to 21.9 million as of

December 31, 2016. For official members who visited our platform in each month of 2016, our 12th-month retention rate was above 79.0%.

Our users also actively engage with a variety of social features offered on our platform, such as sending B-chats, commenting and messaging, as well as interactive features that enable them to interact with content creators, such as sending free or paid virtual items to show their support and appreciation. In 2017, we had an average of 15.2 million monthly active users who participated in social interactions, generating a total of 221.1 million interactions on a monthly basis, as compared to 8.4 million and 113.5 million in 2016. In the fourth quarter of 2017, 75.0% of our official members participated in social interactions.

We are one of the all-inclusive multi-media platforms in China that offer a full spectrum of entertainment content, including PUG videos, licensed videos, live broadcasting, short video clips, pictures, blogs and mobile games. Our content offerings cover a wide variety of themes, among which lifestyle, game, variety shows and celebrity, TV and film-related reviews and technology were the five most popular themes in terms of number of video views in the fourth quarter of 2017. The average time spent for entertainment content offered on our platform spans widely from less than one minute to more than an hour, depending on the format and genre of the content:

Professional user generated videos, or PUG videos, have recently emerged as a highly popular category of content as it combines the content breadth offered by user generated content and the quality and specialization offered by professional generated content. With the development of affordable and easy-to-use hardware including digital camcorders and mobile devices with high-resolution video cameras, as well as advances in software technology such as desktop editing software, the barrier for producing quality video content is gradually vanishing. Video production is now done by a wide range of participants, from amateurs, to professional users who have certain level of production and editing capabilities and to professionals from production studios or workshops, and the lines that separate each category of content providers are becoming increasingly blurred.

We offer content creators tools and outlets for individualized creative expression outside traditional mainstream content formats. Since our inception in 2011, our PUG video content has experienced strong growth in terms of not only the number of users who upload videos produced or aggregated by themselves, but also the number and varieties of videos uploaded every day and the number of daily video views. In the fourth quarter of 2017, an average of approximately 31,400 new submissions were made to our platform each day, covering a wide range of interest areas including anime, game, music, fashion, lifestyle and technology, and different editorial styles such as live documentary, spoof videos and others, as compared to a daily average of approximately 14,300 new submissions in the same period of 2016. PUG videos are popular among and well received by our users due to their originality and creativity as well as their sharing and interactive characteristics. In 2017, PUG video views accounted for approximately 85.5% of our total video views, as compared to 74.5% in 2016.

Licensed videos are another important category of our content offerings. Our licensed videos mainly include anime, television serial drama, movies, documentaries and variety shows. We believe that we have one of the largest libraries for anime and documentaries in China. We have partnered with reputable content providers for licensed videos, including leading PRC and overseas television networks and studios.

We strive to acquire content that is appealing to Generation Z as this demographic group forms the substantial majority of our existing users. In addition, we have been a strong advocate of Chinese traditional culture and have made conscious efforts to help our users discover and understand China's rich and profound history and cultural heritage through our content offerings. For example, we procured Chinese amines such as Monkey King: Hero is Back, an animated movie featuring the hero of one of the four most well-known Chinese classic novels, Journey to the West, and documentaries such as Masters in the Forbidden City, a documentary featuring the Forbidden City's cultural relics and the unsung life stories of conservator-restorers of cultural relics working inside the Forbidden City, and Finding Craftsmanship, a five-episode documentary series that recounts the trip of three individuals traveling around China to find the best craftsmanship and craftsman. Each of them has enjoyed great popularity among our users.

Live broadcasting provides an open venue for users to register and set up channels so that viewers with common interests can gather online and interact with hosts and among themselves. Unlike traditional recorded videos, live broadcasting allows the users to interact with the hosts on a real-time basis and therefore facilitates a more vibrant social experience among hosts and users. Our live broadcasting channels cover a wide array of interests including music, dancing, drawing, ACG, animals and pets, and lifestyle.

Our live broadcasting content differs from that offered on many other live broadcasting platforms as our users primarily utilize live broadcasting as an arena to display and showcase their artistic talents. To date, music, dancing and drawing shows have accounted for a substantial majority of the content offered on our live broadcasting program. Furthermore, we provide diversified live broadcasting content instead of relying on specific hosts to attract users.

Besides PUG videos, our users can also upload shorter and more spontaneous video clips made by amateurs using mobile phones with video camera functions. To facilitate the instant creation, sharing and viewing of content, we launched a feature that allows users to record and upload short video clips directly on our mobile app in November 2016. Our friendly interface enables users to record and edit short video clips entirely on their mobile devices. The length of a short video clip on our platform ranges from 10 to 233 seconds and is generally less than one minute. This feature has been well-received by our users. In addition, we also launched features in October 2016 that allow user to upload pictures of cosplay, drawings and paintings, fashion as well as blogs to further increase the variety of content formats we provide to our users and content creators.

There are a large population of game lovers among our users. Game is the second most popular genre on our platform based on video views in the fourth quarter of 2017. We offer animation and comics themed mobile games that are compatible with our communities and user preferences, some of which are designed based on popular content on our platform. The games we offer are all immersive games, covering some of the most popular and engaging genres, such as massively multiplayer online role-playing games. In these games, users play online in a virtual environment existing on network game servers that connect a large number of players simultaneously to interact with each other within the games.

We have achieved a strong growth in mobile game content offering and strong growth in mobile game active users. As of December 31, 2017, we operated eight exclusively distributed mobile games, 63 jointly operated mobile games and one self-developed mobile game.

The most popular mobile games on our platform include Fate/Grand Order and Azur Lane. Fate/Grand Order is an online role playing game based on the Fate series, an anime collective that began with the visual novel Fate/stay night and has since gathered a number of derivative works and adaptations bearing the same "Fate" name. Animation of the series have been viewed more than 180 million times in aggregate on our platform. Noticing the popularity of the Fate series on our platform, we strategically localized and launched Fate/Grand Order on an exclusive basis in China in September 2016. The game attracted 4.5 million players within the first 30 days after launch.

We encourage and support content creators' creation of original PUG videos, which has been the primary source of user traffic and the key driver for the growth of our user base and communities. In 2017, we had approximately 204,100 average monthly active content creators, compared to approximately 100,200 in 2016, and received an average of approximately 835,900 monthly video submissions in 2017, compared to approximately 358,100 in 2016, and 68.6% of the submissions were original PUG videos. As of December 31, 2017, the number of content creators with more than 10,000 followers had more than doubled since December 31, 2016. Below are stories of some of the most popular and influential content creators on our platform and screenshots of their representative videos:


		" " (Yaorenmao) is a dance-themed content creator and popular dancer on our platform. She began to upload videos on our platform since 2011. As a member of a user-idol group named "Team 155", she became a representative figure of ACG-inspired dance culture in China because of her "adorkable" style. As of December 31, 2017, she had uploaded a total of 76 videos that attracted 110 million views and had approximately 1.6 million followers on our platform. Her most popular video has been viewed more than 12 million times.
		" " (Fulinfang) is a lifestyle-themed content creator and a British living in China. He began to upload videos on our platform since 2015. In his videos, he talked about many Sino-British cultural differences he observed in an interesting and humorous way and fun anecdotes of foreigners living in China, and is well-liked by our users. As of December 31, 2017, he had uploaded a total of 426 videos that were played more than 122 million times and had approximately 1.7 million followers on our platform.
		" Moyun" is a music-themed content creator and is currently studying abroad. She began to upload videos on our platform since 2014. Her superb "zither" skills have earned her great fame among our users, and she is considered a key figure in leading the revival of traditional Chinese culture by many of our users. As of December 31, 2017, she had approximately 779,500 followers on our platform, and her video "Senbon Zakura" was the most popular video on our platform and had been viewed more than 15 million times.

It is essential for us to have our network of content creators upload and contribute quality PUGC to our platform, especially PUG videos. We have taken a number of initiatives to encourage and facilitate production of creative PUG videos by content creators. We also entered into contracts with select content creators and offer them economic incentives to compensate and reward them for the quality contents generated on our platform. Most of these content creators are individuals or studio teams that enjoy great popularity on our platform. We plan to enter into more contracts with content creators to incentivize them to continue to generate popular and appealing PUGC. We have also introduced certain creative, quality PUGC to advertisers directly to create revenue-generating opportunities for content creators.

Our platform includes our "bilibili" mobile app, mobile and PC websites and a variety of related features, functionalities, tools and services that we provide to users and content creators. For mobile devices, users typically access our content through our dedicated "bilibili" mobile app or a mobile website that is largely similar in terms of functionality and appearance to our mobile app. Our mobile app is available for user download from the Apple and Android app stores. We also provide a PC website at www.bilibili.com. The majority of our active users are on mobile, and our mobile products continue to grow faster than our PC products.

We utilize our big data analytical capabilities in our feed system to categorize and recommend content based on user data captured on our platform and analytics produced by our deep learning algorithms. The basic features we offer on our platform include content uploading, viewing and commenting. Our platform also can categorize, rank, search for, curate and recommend content

uploaded and viewed to simplify the content discovery process. Below are screenshots of our mobile app interface, mobile website interface and PC website interface:

Our communities are built on creative content as well as vibrant interactions among users. Users' interactions on our platform revolve around content. Content is also the media for users who share similar interests and hobbies to find and engage with each other and establish a common bond. We provide the following social and interactive features for our users. Through these features, our users from different backgrounds develop strong and positive relationships among themselves, and bond over common values where each user's backgrounds and circumstances are appreciated and positively valued.

Bullet chatting. Bullet chatting is a live commenting function that enables content viewers to send comments that fly across the screen like bullets, and has become very popular among young internet users in China. We essentially pioneered the bullet chatting culture in China when we launched our website, and only registered users who passed our membership exam can send B-chats on our platform. B-chats are frame- and context-specific and can be seen by all viewers who watch the same content at different times, and therefore can intrigue interactive commenting among content viewers. The bullet chatting feature has transformed the video-viewing experience by displaying thoughts and feelings of other audience viewing the same video and thus introducing additional meaning and context beyond what can be communicated by the content itself.

For example, when viewing the documentary Masters in the Forbidden City, users can also see previous viewers' B-chats, which provide introduction on the artwork contained in the documentary, background stories of the conservator-restorers of historic and artistic works and detailed explanations of the incredible skills those conservator-restorers displayed in restoring these artworks. Users are therefore exposed to additional information and different perspectives when they watch the documentary on our platform, and are able to communicate with each other and bond over the viewing experience. This unique and immersive viewing experience successfully drives significant traffic and

promotes the less visited genre of Chinese documentary to the mainstream audience base. As of December 31, 2017, this documentary had been viewed over 3.0 million times on our platform since its release on our platform in February 2016. Below is a screenshot of the documentary:

Liking and following. Users can like content in several ways to encourage content creators, such as giving a "thumbs up", voting and adding to favorites. Users can also opt to follow a content creator, and then they will be able to see such content creator's timeline posts.

Interacting with fans. Content creators can use timeline and fans group to interact with their fans. Timeline enables users to express and share their interests and stories in the form of text and multimedia content such as pictures and short video clips. Content creators can utilize this feature to notify their followers when they upload and release new content on our platform. In addition, users can join fans group to interact with content creators, live broadcasting hosts and other followers.

Gifting and rewarding. Users can send free or paid virtual items to live broadcasting hosts and content creators to show their support and appreciation.

Sharing and communicating. Users can share and repost content uploaded by other users, add comments, send instant messages and view their history of interactions with other users.

Community events. Every year, we hold large festivals and community events for our users, including New Year Gala, Bilibili Dancing Festival and MOE Anime Character Popularity Contest. We invite content creators and hosts of our live broadcasting program to participate in the preparation of some of these events. New Year Gala is our signature community event that we started in 2010 where we invite all content creators to create and upload ACG-inspired videos and select the best among them to produce an extended program according to each year's theme to celebrate Chinese New Year with our

users. As of December 31, 2017, our 2017 New Year Gala had been viewed more than 22 million times and generated 2.0 million B-chats. Below is a screenshot of New Year Gala's interface:

It is essential to have our network of content creators upload and contribute quality content to our platform. We have developed the following support features and applications to encourage and facilitate production of creative content by content creators.

Uploading tools. We have developed a variety of uploading tools to enable users to efficiently upload multi-media content, including videos in different length, pictures, blogs and other forms of content. Some of our uploading tools also contain editing features which can help users add a variety of visual and audio effects to the content.

Analytic tools. Our analytic tools allow users to see a range of backstage data, such as demographics of followers and viewers, and data on user behavior, such as following/un-following, viewing, commenting and bullet chatting. Such information gives content creators insights into current

trends and user preferences and help content creators improve and make their creative work more relevant.

The vitality and integrity of our communities are cornerstones of our business. Our users come to our platform for creative content as well as for our strong and vibrant community culture. To preserve our culture and community values, we have employed the following features in operating our communities.

Membership exam for registered users. Registered users need to pass our multiple-choice membership exam consisting of 100 questions in order to become our "official members", after which additional interactive and community features, such as bullet chatting and commenting, will become available to them. In the membership exam, 30 out of 100 questions are on community etiquette regarding uploading videos and sending B-chats, and registered users must answer all of them correctly in order to pass the membership exam. In addition, registered users need to answer another ten questions on community culture and then choose 60 questions from a range of topics with which they are familiar, such as anime, music, games and technology, and answer a total of 30 questions correctly to pass the membership exam. Only those registered users who have passed our membership exam are eligible to upload content to our platform. Our membership examination system has promoted fairness

and fostered a strong sense of belonging and ownership among our users. As of December 31, 2017, we had 31.6 million official members who passed our membership exam.

Community management. Our veteran users have voluntarily formed a community discipline committee to monitor and report any inappropriate content that has been posted on our platform, which has proven to be an effective means to regulate our users' behavior in our communities. To support their efforts, we have worked with and provided them with technical means to help them carry out their activities more effectively and enforce their disciplinary decisions. If we confirm that a user has uploaded content that contains provocative and hate speech, personal attacks, fraudulent information or other offensive information, we may temporarily suspend or permanently terminate such user's account, and display such user's account information and reason for the disciplinary action under "Dark Chamber" tab, which is open to all users on our platform. This measure also allows users to participate in the management of our communities and helps us educate users and foster a self-regulating environment to protect and strengthen the community values that we hold dear. See "—Content Management and Review."

Our monetization efforts are based on the integrated goals of offering quality content to attract users, building vibrant communities to retain users, and stimulating content consumption to achieve monetization. We generate revenues primarily from mobile games, live broadcasting and VAS, and advertising services.

We started to publish mobile games on our platform for third-party developers in January 2014, and launched our first self-developed game in August 2017. Our users access the mobile games on our platform and log into and play with their bilibili accounts. They purchase in-game virtual items that enhance their game-playing experience. The mobile games on our platform are selected and curated

based on content, themes, cultural characteristics and features that appeal to the existing users in our communities.

As of December 31, 2017, we operated eight exclusively distributed mobile games, 63 jointly operated mobile games and one self-developed mobile game. For our exclusively distributed mobile games, we generally were granted royalty-bearing license with the exclusive right to market and distribute mobile games in China. We also entered into joint operating agreements with game developers and distributors pursuant to which we were granted non-exclusive licenses to promote and distribute games on our platform.

We routinely customize our exclusively distributed mobile games and adapt them to our users' preferences and provide operation and servicing support with our own servers to optimize the game experience for our users. For jointly operated mobile games, we generally provide publishing, payment solutions and market promotion services, while game developers are responsible for providing game products, hosting and maintenance of game servers and determining the pricing of in-game virtual items.

The high relevance and popularity of our game content has translated into sizeable active user base and high conversion of active users and paying users from our video platform. In 2017, our monthly active users for mobile games were 9.1 million, as compared to 3.1 million in 2016.

We offer various live broadcasting content covering a broad range of interests and topics. We offer various virtual items for sale on our live broadcasting program. These virtual items can produce special effects on the screen, such as storms and fireworks. These items can be purchased with the virtual currency on our platform named "B-coin". Each B-coin is worth RMB1. Users can also use B-coins to purchase virtual items on other parts of our platform, and send the virtual items to their favorite content creators to show appreciation and provide them with monetary rewards.

We share with the hosts the revenues generated on our live broadcasting program. We have entered into exclusive cooperation agreements with certain popular hosts on our platform, pursuant to which we agreed to pay certain level of salary to these hosts in addition to the revenue-sharing arrangements, and we plan to enter into cooperation agreements with more hosts in the future to secure popular hosts and further expand our live broadcasting program.

We offer advertisers with customized advertising services to help them deliver advertising cost-effectively to their targeted audience. We value user experience, and strive to creatively utilize our integrated service interface in designing a particular advertising campaign for advertisers by focusing on the content, style, design and interactive features of the advertisements so that they will appear native to our users. We also take into account the preferences and tastes of our users in selecting advertisers. Furthermore, by working with our popular content creators to offer in-program advertisements, we are able to offer these creators additional monetary rewards for their contribution, which in turn enhances their loyalty to our platform and incentivizes them to create more appealing content.

We offer advertising services in different placement formats, including (i) background advertisements that appear above or below a selected video screen concurrently with a user viewing a video, (ii) advertisements placed at the launch screen of our mobile apps and (iii) in-program advertisements. In late 2017, we launched performance-based feed advertising service on our platform. Our brand advertisers include international and domestic companies that operate in a variety of industries, including consumer retail, electronic products and games. We also work with our popular content creators and offer brand advertisers customized in-program advertisements.

Our technology platform has been designed for reliability, scalability and flexibility and is administered by our in-house technology department. We have access to a network of 4,300 self-owned and more than 1,800 leased servers across China with power supply and power generator backup. This structure, along with other features described below, contributes to the reliability, scalability and efficiency of our network.

Artificial intelligence. Artificial intelligence, or AI, is particularly suitable for reviewing and screening content by recognizing and analyzing patterns and connections. The massive volume of data collected on our platform every day also enables us to enhance our AI technology and increase its accuracy. As the varieties and quantity of content and user interactions continue to increase, AI capabilities are critical for us to control our operating costs and enhance user experience.

Big data analytics. We utilize big data analytics to create an interest profile for each user account based on user's actions such as post, bullet chatting, comment, like and follow, and demographic data such as age, gender and geography. Combined with our AI capabilities, our interest profile allows us to personalize user interface and push content to our users that they are more likely to find interesting and relevant.

Cloud. Due to the nature of the products and services we offer, we have a high demand for storage and computing capacities to enhance the functionalities of our web video player, store and support massive volume of data being generated every day on our platform, and run algorithms to produce content recommendations. We have developed an advanced cloud system that meets the operational needs of our platform while reducing operating costs.

Content distribution network. Our web server technology focuses on reducing bandwidth use while enhancing user experience through utilizing our content distribution network, or CDN, system. A copy of data is being placed at various points in our CDN to maximize bandwidth for access to the data from users throughout the network. Our CDN components are strategically deployed in the cities where our users concentrate, enabling users to access a copy of the data closet to them so that content loading time is minimized. Our proprietary CDN system enhances network efficiency by managing and optimizing the workload of the servers through real-time optimization and distribution. This technology allows users to upload content without compression and enables viewing of content in higher definition.

Real-time monitoring and support. Our internet data center and regional data center servers automatically report any detected malfunction on a real-time basis to our network control center. This allows us to quickly respond to and resolve network and other malfunction issues. We have a network operation support team responsible for stability and security of our network on a 24-hour, seven-days-a-week basis. The primary responsibilities of the team members consist of monitoring system performance, troubleshooting, detecting system error, random sample testing on servers, maintaining equipment, and testing, evaluating and installing hardware and software.

Data back-up technology. Different servers share and back up the data of one another, which increases the security of our network by allowing us to provide backup to failed servers and prevent system-wide failures caused by area network failures.

We are passionate about developing new and innovative products and services that will create more exciting experience for our users. As of December 31, 2017, our technology team consisted of 839 members, including software engineers, designers, and product managers. They are responsible for developing, operating and maintaining our app/websites, live broadcasting program, cloud-based databases, social media, mobile games and online communities.

We seek to protect our technology, including our proprietary technology infrastructure and core software system, through a combination of patents, copyrights, trademarks, trade secrets and confidentiality agreements. As of December 31, 2017, we have registered 21 patents, 64 registered copyrights, 140 registered domain names, including www.bilibili.com, and 686 registered trademarks, including " ". In addition, we had submitted 122 additional patent applications and 489 trademark applications.

We intend to protect our technology and proprietary rights vigorously, but there can be no assurance that our efforts will be successful. Even if our efforts are successful, we may incur significant costs in defending our rights. From time to time, third parties may initiate litigation against us alleging infringement of their proprietary rights or declaring their non-infringement of our intellectual property rights. See "Risk Factors—Risks Related to Our Business and Industry—We may be subject to intellectual property infringement claims or other allegations, which could result in material damage to our reputation and brand image, payment of substantial damages, penalties and fines, removal of relevant content from our platform or seeking license arrangements which may not be available on commercially reasonable terms" and "Risk Factors—Risks Related to Our Business and Industry—We may not be able to prevent others from unauthorized use of our intellectual property, which could harm our business and competitive position."

We have built our brand and user communities with modest marketing expenditures to date as we primarily rely on viral marketing, word of mouth referrals and repeat user visits driven by superior user experience. We are focused on improving the quality of our content and product offerings, as well as user experience. We believe that the better our content and product offerings become, the more users we will attract and retain, which in turn incentivizes more content creators to contribute creative and appealing content to our platform, thus forming a self-reinforcing virtuous cycle. Our market position benefits significantly from our large user base and our strong brand recognition in China.

In addition, we have initiated various marketing activities to further promote our brand awareness among existing and potential users and advertisers. For example, we market our services through direct marketing, trade shows and other media events.

The vitality and integrity of our communities are cornerstones of our business. We dedicate significant resources to the goal of strengthening our communities through developing and implementing programs designed to protect user privacy, promote a safe environment, and ensure the security of user data.

Our users come to our platform for creative content as well as for our strong, vibrant and safe communities. We consider the protection of the personal privacy of each of our users to be of paramount importance. The user privacy section of our user agreement describes our data use practices and how privacy works on our platform. Specifically, we provide users with adequate notice as to what data are being collected and undertake to manage and use the data collected in accordance with applicable laws and make reasonable efforts to prevent the unauthorized use, loss or leak of user data. In addition, we use a variety of technologies to protect the data with which we are entrusted and have a team of privacy professionals dedicated to the ongoing review and monitoring of data security practices. For example, we store all user data in encrypted format and strictly limit the number of personnel who can access those servers that store user data. For our external interfaces, we also utilize firewalls to protect against potential attacks or unauthorized access.

We are committed to the protection of third-party copyrights. We have invested significant resources to develop robust copyright protection technologies and policies.

We maintain two levels of content management and review procedures to monitor the content uploaded to our platform to help ensure that no content that may be deemed to be prohibited by government rules and regulations is posted and to promptly remove any infringing content. The first level of review procedure is conducted through our proprietary artificial intelligence-based screening system. This system automatically flags and screens out newly uploaded videos that have piracy issues or contain illegal or inappropriate content by comparing them with copyrighted or objectionable videos stored in our own in-house "black list" databases and identifying those with similar codes. Once the content is processed by our technology screening system, our system then extracts fingerprint trails from the content and sends them to our content screening team for the second-level review. As of the date of this prospectus, our content screening team consists of over 200 employees dedicated to screening and monitoring the content uploaded on our platform on a 24-hour, 7-day basis. They work around the clock to ensure that the flagged content identified by our screening system is reviewed and confirmed before it can be released. We provide initial training during the onboarding process for new hires. We also offer periodic training sessions to keep these employees apprised of any regulatory and policy changes, and supervise and monitor their work. All of the content needs to go through these two levels of review procedures before it is released on our platform.

All of the other content, primarily consisting of B-chats posted by users, is also automatically filtered by our screening system, which utilizes an artificial intelligence-based screening system to conduct semantic analysis on B-chats to analyze, identify and screen out inappropriate B-chats. With respect to live broadcasting, we have a separate monitoring team to review and monitor the content and activities of hosts of our live broadcasting program as well as the B-chats posted by viewers.

We utilize a real-name system to authenticate the identities of our content creators and live broadcasting hosts. In addition, before each upload, we require the user to confirm that the user has agreed to the terms and conditions set forth in the user agreement of our platform. Pursuant to such user agreement, each user undertakes not to upload or distribute content that violates any PRC laws or regulations or infringes the intellectual property rights of any third party, and agrees to indemnify us for all damages arising from third-party claims against us caused by violating or infringing content uploaded or linked by the user. Cooperation agreements with our popular content creators also provide for standard clauses that restrict the content creators from uploading infringing content on our platform. We also remove users' uploads when we are notified or made aware by copyright owners or from other sources authorized by copyright owners of copyright infringements, such as lists of inappropriate or infringing content that the regulatory authorities publish from time to time and market information on releases of movies and television serial drama.

Our abuse reporting infrastructure also allows any of our users to report inappropriate, offensive or dangerous content to us through "report" links easily found on our platform. We have enhanced this reporting system with our community discipline committee, which is comprised of our veteran users who volunteer to monitor and report any inappropriate content that has been posted on our platform. In addition, if we confirm that user has uploaded content that contains provocative and hate speech, personal attacks, fraudulent information or other offensive information, we may temporarily suspend or permanently terminate such user's account, and display such user's account information and reason for the disciplinary action under "Dark Chamber" tab, which is open to all users on our platform.

Our business is characterized by innovation, rapid change and disruptive technology. We face significant competition primarily from companies that operate online entertainment platforms in China

designed to engage users, especially Generation Z, and capture their time spent on mobile devices and online. In particular, our competitors mainly include large online video streaming platforms, social media platforms and other platforms offering video products. We compete to attract, engage and retain users, to attract and retain advertisers, and to attract and retain content providers to improve and expand our content library and unique offerings. Our competitors may compete with us in a variety of ways, including by obtaining exclusive online distribution rights for popular content, conducting brand promotions and other marketing activities, and making acquisitions. We have exclusive distribution rights only for certain PUGC content on our platform. Our content creators are generally free to post their content on our competitors' platforms, which may divert user traffic from our platform.

We believe that we can compete effectively with our competitors on the basis of the following factors: (i) the strength and reputation of our brand, (ii) our ability to provide creative and quality PUGC, (iii) the demographic composition and engagement of our user base, (iv) the performance and reliability of our platform, and (v) our ability to develop new products and services and enhancements to existing products and services to keep up with user preferences and demands.

As we introduce new products and services on our platform, as our existing products continue to evolve, or as other companies introduce new products and services, we may become subject to additional competition.

We had 1,094 and 1,903 employees as of December 31, 2016 and 2017, respectively. The following table sets forth the numbers of our employees categorized by function as of December 31, 2017:

As of December 31, 2017, we had 1,816 employees in Shanghai, 23 employees in Beijing and 64 employees in other locations.

As required under PRC regulations, we participate in housing funds and various employee social security plans that are organized by applicable local municipal and provincial governments, including housing, pension, medical, work-related injury and unemployment benefit plans, under which we make contributions at specified percentages of the salaries of our employees. We also purchase commercial health and accidental insurance for our employees. Bonuses are generally discretionary and based in part on employee performance and in part on the overall performance of our business. We have granted and plan to continue to grant share-based incentive awards to our employees in the future to incentivize their contributions to our growth and development.

We enter into standard confidentiality and employment agreements with our key employees. The contracts with our key personnel typically include a standard non-compete agreement that prohibits the employee from competing with us, directly or indirectly, during his or her employment and for at least one year after the termination of his or her employment.

We believe that we maintain a good working relationship with our employees and we did not experience any significant labor disputes or any difficulty in recruiting staff for our operations.

Our headquarters is located at Wujiaochang commercial district in Shanghai, where we lease and occupy the office building with an aggregate floor area of approximately 18,325 square meters. A substantial majority of our employees are based at our headquarters in Shanghai. Our servers and network facilities for internal administrative functions are located at our headquarters. We also lease and occupy an office building located at Pudong Avenue in Shanghai with an aggregate floor area of approximately 810 square meters. We have sales and marketing, accounting and anime production personnel as well as game development teams at our regional offices in Beijing and Tokyo. We lease and occupy approximately 283 square meters of office space in Beijing and approximately 611 square meters of office space in Tokyo. These leases vary in duration from one to ten years.

We do not maintain insurance policies covering damages to our network infrastructures or information technology systems. We also do not maintain business interruption insurance or general third-party liability insurance, nor do we maintain product liability insurance or key-man insurance. We consider our insurance coverage to be in line with that of other companies in the same industry of similar size in China.

Industry Catalogue Related to Foreign Investment. Investment activities in China by foreign investors are principally governed by the Guidance Catalogue of Industries for Foreign Investment, which was promulgated by MOFCOM and the National Development and Reform Commission, as amended from time to time. Industries listed in the catalogue are divided into three categories: encouraged, restricted and prohibited. Industries not listed in the catalogue are generally open to foreign investment unless specifically restricted by other PRC regulations. Establishment of wholly foreign-owned enterprises is generally allowed in encouraged industries. For some restricted industries, foreign investors can only conduct investment activities through equity or contractual joint ventures, while in some cases PRC partners are required to hold the majority interests in such joint ventures. In addition, projects in the restricted category are subject to higher-level governmental approvals. Foreign investors are not allowed to invest in industries in the prohibited category.

Foreign Investment in Telecommunication Business. Regulations for Administration of Foreign-Invested Telecommunications Enterprises, promulgated by the PRC State Council in 2001 and most recently amended in February 2016, set forth detailed requirements with respect to, among others, capitalization, investor qualifications and application procedures in connection with the establishment of a foreign-invested telecommunications enterprise.

In addition, such company's operation premises and equipment must comply with its approved ICP License, and such company should establish and improve its internal internet and information security policies and standards and emergency management procedures.

In 2000, the PRC State Council promulgated the Telecommunications Regulations, most recently amended in February 2016.

Value-added telecommunications services are defined as telecommunications and information services provided through public network infrastructures. The "Classified Catalogue of Telecommunications Services", an attachment to the Telecommunications Regulations, most recently updated in December 2015, categorizes various types of telecommunications and telecommunications-related activities into basic or value-added telecommunications services. According to the catalogue, internet information services, or ICP services, are classified as value-added telecommunications services. Under the Telecommunications Regulations,

In 2004, the MOC promulgated Notice on Strengthening the Examination of Online Game Product Content, pursuant to which, the MOC has set up a content review committee which is responsible for examining the contents of imported online game products. The office of the review committee is responsible for the daily work of the examination of the contents of the imported online game products. In 2010, the MOC promulgated the Provisional Measures on the Administration of Online Games, as most recently amended in 2017, pursuant to which ICP service operators engaging in any activities involving the operation of online games, issuance or trading of virtual currency shall obtain the Online Culture Operating Permit. Regarding virtual currency trading, ICP service operators can only issue virtual currency in exchange of the service provided by itself rather than trading for service or products for the third parties. ICP service operators cannot appropriate the advance payment by the players and are not allowed to provide trading service of virtual currencies to the minors. All the transactions in the accounts shall be kept in records for minimum 180 days.

In addition, in 2007, the MOC, the People's Bank of China and other relevant governmental authorities jointly issued the Notice on Further Strengthening Administrative Work on the Internet Cafes and Online Games, or the Internet Cafes Notice, pursuant to which the People's Bank of China is directed to strengthen the administration of virtual currency in online games to avoid any adverse impact on the economy and financial system.

In the event of any failure to meet these license and approval requirements, an operator may face heavy penalties, such as being ordered to stop operation, or having its business license revoked.

Regulations Related to Anti-fatigue System, Real-name Registration System and Parental Guardianship Project

In 2007, the GAPP and several other government agencies issued a circular requiring the implementation of an anti-fatigue system and a real-name registration system by all PRC online game operators to curb addictive online game playing by minors. Under the anti-fatigue system, three hours or less of continuous playing by minors, defined as game players under 18 years of age, is considered to be "healthy," three to five hours to be "fatiguing," and five hours or more to be "unhealthy." Game operators are required to reduce the value of in-game benefits to a minor player by half if the minor has reached the "fatiguing" level, and to zero once reaching the "unhealthy" level.

To identify whether a game player is a minor and thus subject to the anti-fatigue system, a real-name registration system must be adopted to require online game players to register their real identity information before playing online games. The online game operators are also required to submit the identity information of game players to the public security authority for verification. In 2011, the GAPP, together with several other government agencies, jointly issued the Notice on Initializing the Verification of Real-name Registration for the Anti-Fatigue System on Online Games, or the Real-name Registration Notice, to strengthen the implementation of the anti-fatigue and real-name registration system. The main purpose of the Real-name Registration Notice is to curb addictive online game playing by minors and protect their physical and mental health. This notice indicates that the National Citizen Identity Information Center of the Ministry of Public Security will verify identity information of game players submitted by online game operators. The Real-name Registration Notice also imposes stringent penalties on online game operators that do not implement the required anti-fatigue and real-name registration systems properly and effectively, including terminating their online game operations.

In 2011, the MOC, together with several other government agencies, jointly issued a Circular on Printing and Distributing Implementation Scheme regarding Parental Guardianship Project for Minors Playing Online Games to strengthen the administration of online games and protect the legitimate rights and interests of minors. This circular indicates that online game operators must have person in charge, set up specific service webpages and publicize specific hotlines to provide parents with necessary assistance to prevent or restrict minors' improper game playing behavior. Online game operators must also submit a report regarding its performance under the Parental Guardianship Project to the provincial level counterpart of the MOC each quarter.

The SAPPRFT is the governmental agency responsible for regulating publishing activities in China. In February 2016, the MIIT and the SAPPRFT jointly promulgated the Administrative Provisions on Online Publishing Services, or the Online Publishing Provisions, which took effect in March 2016. According to the Online Publishing Provisions, all online publishing services provided within the territory of China are subject to the Online Publishing Provisions, and an online publishing services permit shall be obtained to provide online publishing services.

In May 2017, in order to ramp up the efforts to clean up infringements and counterfeiting in the field of internet, the General Office of the State Council further issued "Circular of the General Office of the State Council on Issuing the Major Tasks in Nationwide Crackdown on the Infringement of Intellectual Property Rights and Production and Sale of Counterfeit and Shoddy Goods in 2017." Meanwhile, the regulatory authorities have been conducting an annual "Clean Up the Internet" campaign in the past several years to combat the internet infringement of intellectual property.

The PRC authorities have adopted comprehensive legislation governing intellectual property rights, including copyrights, patents and trademarks.

Under the Copyright Law, issued in 1990 and most recently amended in 2010, or the Copyright Law, and its related Implementing Regulations, issued in 2002 and amended in 2013, creators of protected works enjoy personal and property rights with respect to publication, authorship, alteration, integrity, reproduction, distribution, lease, exhibition, performance, projection, broadcasting, dissemination via information network, production, adaptation, translation, compilation and related activities. The term of a copyright, other than the rights of authorship, alteration and integrity of an author shall be unlimited in time, is life plus 50 years for individual authors and 50 years for corporations. In consideration of the social benefits and costs of copyrights, the PRC authorities balance copyright protections with limitations that permit certain uses, such as for private study, research, personal entertainment and teaching, without compensation to the author or prior authorization.

To address the problem of copyright infringement related to the content posted or transmitted over the internet, the PRC National Copyright Administration and MII jointly promulgated the Measures for Administrative Protection of Copyright Related to Internet, effective 2005. These measures apply to acts of automatically providing such functions as uploading, storing, linking or searching works, audio or video products, or other contents through the internet based on the instruction of website users who publish contents on internet, without editing, amending or selecting any stored or transmitted content. A copyright administration authority shall, when imposing administrative penalties upon the act infringing upon the right of communication through information network, apply the Measures for Imposing Copyright Administrative Penalties issued by the PRC National Copyright Administration in 2009.

The State Council promulgated the Regulation on Protection of the Right of Communication through Information Network, effective in 2006 and amended in March 2013. Under this regulation, an ICP service provider may be exempted from indemnification liabilities under the following circumstances:

In December 2012, the Supreme People's Court of China promulgated the Provisions on Certain Issues Related to the Application of Law in the Trial of Civil Cases Involving Disputes over Infringement of the Right of Dissemination through Information Networks, which provides that the courts will require ICP service providers to remove not only links or content that have been specifically mentioned in the notices of infringement from rights holders, but also links or content they "should have known" to contain infringing content. The provisions further provide that where an ICP service provider has directly obtained economic benefits from any content made available by an internet user, it has a higher duty of care with respect to internet users' infringement of third-party copyrights.

The National People's Congress adopted the Patent Law in 1984, as most recently amended in 2008. A patentable invention, utility model or design must meet three conditions: novelty, inventiveness and practical applicability. Patents cannot be granted for scientific discoveries, rules and methods for intellectual activities, methods used to diagnose or treat diseases, animal and plant breeds or substances obtained by means of nuclear transformation. The Patent Office under the State Council is responsible for receiving, examining and approving patent applications. A patent is valid for a twenty-year term in the case of an invention and a ten-year term in the case of a utility model or design, starting from the application date. A third-party user must obtain consent or a proper license from the patent owner to use the patent except for certain specific circumstances provided by law. Otherwise, the use will constitute an infringement of the patent rights.

Registered trademarks are protected under the Trademark Law adopted in 1982 and most recently amended in 2013. The PRC Trademark Office of the State Administration for Industry and Commerce is responsible for the registration and administration of trademarks throughout China. The Trademark Law has adopted a "first-to-file" principle with respect to trademark registration. Where a trademark for which a registration has been made is identical or similar to another trademark that has already been registered or been subject to a preliminary examination and approval for use on the same kind of or similar commodities or services, the application for registration of such trademark may be rejected. Any person applying for the registration of a trademark shall not prejudice the existing right of others obtained by priority, nor shall any person register in advance a trademark that has already been used by another person and has already gained "sufficient degree of reputation" through that person's use. After receiving an application, the PRC Trademark Office will make a public announcement if the relevant trademark passes the preliminary examination. Within three months after such public announcement, any person may file an opposition against a trademark that has passed a preliminary examination. The PRC Trademark Office's decisions on rejection, opposition or cancellation of an application may be appealed to the PRC Trademark Review and Adjudication Board, whose decision may be further appealed through judicial proceedings. If no opposition is filed within three months

after the public announcement period or if the opposition has been overruled, the PRC Trademark Office will approve the registration and issue a registration certificate, upon which the trademark is registered and will be effective for a renewable ten-year period, unless otherwise revoked.

The domain names are protected under the Administrative Measures on the Internet Domain Names promulgated by MII, effective in November 2017. The MIIT is the major regulatory body responsible for the administration of the PRC internet domain names, under supervision of which China Internet Network Information Center, or CNNIC, is responsible for the daily administration of CN domain names and PRC domain names. CNNIC promulgated the Implementation Rules of Registration of Domain Name, or the CNNIC Rules, effective in May 2012. Pursuant to the Administrative Measures on the Internet Domain Names and the CNNIC Rules, the registration of domain names adopts the "first to file" principle and the registrant shall complete the registration via the domain name registration service institutions. In the event of a domain name dispute, the disputed parties may lodge a complaint to the designated domain name dispute resolution institution to trigger the domain name dispute resolution procedure in accordance with the CNNIC Measures on Resolution of the Domain Name Disputes, file a suit to the People's Court or initiate an arbitration procedure.

In order to further implement the Computer Software Protection Regulations promulgated by the State Council in 2001 and amended in January 2013, the National Copyright Administration issued the Computer Software Copyright Registration Procedures in 2002, which apply to software copyright registration, license contract registration and transfer contract registration.

The principal regulations governing foreign currency exchange in China are the Foreign Exchange Administration Regulations, promulgated by the State Council in 1996 and most recently amended in 2008. Under the PRC foreign exchange regulations, payments of current account items, such as profit distributions and trade and service-related foreign exchange transactions, can be made in foreign currencies without prior approval from SAFE by complying with certain procedural requirements. By contrast, approval from or registration with appropriate governmental authorities is required where Renminbi is to be converted into foreign currency and remitted out of China to pay capital expenses such as the repayment of foreign currency-denominated loans.

In November 2012, SAFE promulgated the Circular of Further Improving and Adjusting Foreign Exchange Administration Policies on Foreign Direct Investment, which substantially amends and simplifies the current foreign exchange procedures. Pursuant to this circular, the opening of various special purpose foreign exchange accounts, such as pre-establishment expenses accounts, foreign exchange capital accounts and guarantee accounts, the reinvestment of Renminbi proceeds derived by foreign investors in China, and remittance of foreign exchange profits and dividends by a foreign-invested enterprise to its foreign shareholders no longer require the approval or verification of SAFE, and multiple capital accounts for the same entity may be opened in different provinces, which was not possible previously. In addition, SAFE promulgated another circular in May 2013, which specifies that the administration by SAFE or its local branches over direct investment by foreign investors in China must be conducted by way of registration and banks must process foreign exchange business relating to the direct investment in China based on the registration information provided by SAFE and its branches. In February 2015, SAFE promulgated the Notice on Further Simplifying and Improving the Administration of the Foreign Exchange Concerning Direct Investment, pursuant to which, instead of applying for approvals regarding foreign exchange registrations of foreign direct investment and overseas direct investment from SAFE, entities and individuals may apply for such foreign exchange

registrations from qualified banks. The qualified banks, under the supervision of SAFE, may directly review the applications and conduct the registration.

In March 2015, SAFE issued the Circular of the State Administration of Foreign Exchange on Reforming the Management Approach regarding the Settlement of Foreign Exchange Capital of Foreign-invested Enterprises, or SAFE Circular 19. Pursuant to SAFE Circular 19, the foreign currency capital contribution to a foreign invested enterprise, or an FIE, in its capital account may be converted into Renminbi on a discretional basis. Furthermore, in June 2016, SAFE promulgated Circular on Reforming and Regulating Policies on the Control over Foreign Exchange Settlement of Capital Accounts, or SAFE Circular 16, pursuant to which, in addition to foreign currency capital, enterprises registered in China may also convert their foreign debts, as well as repatriated funds raised through overseas listing, from foreign currency to Renminbi on a discretional basis. SAFE Circular 16 also reiterates that the use of capital so converted shall follow "the principle of authenticity and self-use" within the business scope of the enterprise. According to SAFE Circular 16, the Renminbi funds so converted shall not be used for the purposes of, whether directly or indirectly, (i) paying expenditures beyond the business scope of the enterprises or prohibited by laws and regulations; (ii) making securities investment or other investments (except for banks' principal-secured products); (iii) granting loans to non-affiliated enterprises, except as expressly permitted in the business license; and (iv) purchasing non-self-used real estate (except for the foreign-invested real estate enterprises).

In January 2017, SAFE promulgated the Circular on Further Improving Reform of Foreign Exchange Administration and Optimizing Genuineness and Compliance Verification, or SAFE Circular 3, which stipulates several capital control measures with respect to the outbound remittance of profit from domestic entities to offshore entities, including (i) under the principle of genuine transaction, banks shall check board resolutions regarding profit distribution, the original version of tax filing records and audited financial statements; and (ii) domestic entities shall hold income to account for previous years' losses before remitting the profits. Further, pursuant to SAFE Circular 3, domestic entities shall make detailed explanations of the sources of capital and utilization arrangements, and provide board resolutions, contracts and other proof when completing the registration procedures in connection with an outbound investment.

The principal regulations governing the distribution of dividends paid by wholly foreign-owned enterprises include the Wholly Foreign-Owned Enterprise Law issued in 1986 and most recently amended in 2016, and the Implementation Regulations on the Wholly Foreign-Owned Enterprise Law issued in 1990 and most recently amended in 2014. Under these regulations, wholly foreign-owned enterprises in China may pay dividends only out of their accumulated profits, if any, as determined in accordance with PRC accounting standards and regulations. In addition, a wholly foreign-owned enterprise in China is required to set aside at least 10% of its after-tax profit based on PRC accounting standards each year to its general reserves until its cumulative total reserve funds reaches 50% of its registered capital. These reserve funds, however, may not be distributed as cash dividends.

Regulations Related to Foreign Exchange Registration of Offshore Investment by PRC Residents

In July 2014, SAFE issued the Circular of the State Administration of Foreign Exchange on Issues concerning Foreign Exchange Administration over the Overseas Investment and Financing and Round-trip Investment by Domestic Residents via Special Purpose Vehicles, or SAFE Circular 37, to replace the Circular on Several Issues concerning Foreign Exchange Administration for Domestic Residents to Engage in Financing and in Return Investments via Overseas Special Purpose Companies. SAFE Circular 37 regulates foreign exchange matters in relation to the use of special purpose vehicles, or SPVs, by PRC residents or entities to seek offshore investment and financing or conduct round trip investment in China. Under SAFE Circular 37, an SPV refers to an offshore entity established or

controlled, directly or indirectly, by PRC residents or entities for the purpose of seeking offshore financing or making offshore investment, using legitimate domestic or offshore assets or interests, while "round trip investment" refers to the direct investment in China by PRC residents or entities through SPVs, namely, establishing foreign-invested enterprises to obtain the ownership, control rights and management rights. SAFE Circular 37 requires that, before making contribution into an SPV, PRC residents or entities are required to complete foreign exchange registration with SAFE or its local branch. SAFE Circular 37 further provides that option or share-based incentive tool holders of a non-listed SPV can exercise the options or share incentive tools to become a shareholder of such non-listed SPV, subject to registration with SAFE or its local branch. In February 2015, SAFE promulgated the Notice on Further Simplifying and Improving the Administration of the Foreign Exchange Concerning Direct Investment, or SAFE Circular 13. SAFE Circular 13 has amended SAFE Circular 37 by requiring PRC residents or entities to register with qualified banks instead of SAFE or its local branch in connection with their establishment of an SPV.

PRC residents who have contributed legitimate domestic or offshore interests or assets to SPVs but have yet to obtain SAFE registration before the implementation of SAFE Circular 37 shall register their ownership interests or control in such SPVs with SAFE or its local branch. An amendment to the registration is required if there is a material change involving the SPV registered, such as any change of basic information (including change of such PRC residents, change of name and operation term of the SPV), increases or decreases in investment amount, transfers or exchanges of shares, or mergers or divisions. Failure to comply with the registration procedures set forth in SAFE Circular 37 and SAFE Circular 13, misrepresent on or failure to disclose controllers of foreign-invested enterprise that is established through round-trip investment, may result in restrictions on the foreign exchange activities of the relevant foreign-invested enterprises, including payment of dividends and other distributions, such as proceeds from any reduction in capital, share transfer or liquidation, to its offshore parent company or affiliates and the capital inflow from the offshore parent company, and may also subject the relevant PRC residents or entities to penalties under PRC foreign exchange administration regulations.

In February 2012, SAFE issued the Circular of the State Administration of Foreign Exchange on Issues concerning the Administration of Foreign Exchange Used for Domestic Individuals' Participation in Equity Incentive Plans of Companies Listed Overseas, or SAFE Circular 7, replacing the Implementation Rules of the Administrative Measures for Individual Foreign Exchange issued in 2007, to regulate the foreign exchange administration of PRC citizens and non-PRC citizens who reside in China for a continuous period of not less than one year, with a few exceptions, who participate in stock incentive plans of overseas publicly-listed companies. According to SAFE Circular 7 and other related rules and regulations, such individuals who participate in any employee stock ownership plan or stock option plan of an overseas listed company, are required to register with SAFE or its local branches through a qualified PRC agent, which could be the PRC subsidiaries of such overseas listed company or other qualified institution selected by the PRC subsidiaries, and complete other procedures with respect to the stock incentive plan. In addition, the PRC agent is required to amend SAFE registration with respect to the stock incentive plan if there is any material change to the stock incentive plan, the PRC agent or other material changes. The PRC agent must, on behalf of these individuals who have the right to exercise the employee share options, apply to SAFE or its local branches for an annual quota for the payment of foreign currencies in connection with these individuals' exercise of the employee share options. Such individuals' foreign exchange income received from the sale of stocks and dividends distributed by the overseas listed company and any other income shall be fully remitted into a collective foreign currency account in China opened and managed by the PRC subsidiaries of the overseas listed company or the PRC agent before distribution to such individuals. We and our executive officers and other employees who are PRC citizens or non-PRC citizens who reside in China for a continuous

period of not less than one year and have been granted options will be subject to these regulations upon the completion of this offering. Failure of our PRC option holders or restricted shareholders to complete their SAFE registrations may subject us and these employees to fines and other legal sanctions.

In addition, the State Administration for Taxation has issued certain circulars concerning employee share options. Under these circulars, our employees working in China who exercise share options will be subject to PRC individual income tax. Our PRC subsidiaries have obligations to file documents related to employee share options with relevant tax authorities and to withhold individual income taxes of those employees who exercise their share options. If our employees fail to pay or we fail to withhold their income taxes according to relevant laws and regulations, we may face sanctions imposed by the tax authorities or other PRC governmental authorities.

In 2006, six PRC regulatory agencies, including the CSRC, jointly adopted the M&A Rules, amended in 2009. The M&A Rules purport, among other things, to require an offshore special purpose vehicles controlled by PRC companies or individuals and formed for overseas listing purposes through acquisitions of PRC domestic interest held by such PRC companies or individuals, to obtain the approval from the CSRC prior to publicly listing their securities on an overseas stock exchange. In 2006, the CSRC published a notice on its official website specifying documents and materials required to be submitted to it by the offshore special purpose vehicle seeking CSRC approval of its overseas listing. While the application of the M&A Rules remains unclear, our PRC counsel has advised us that based on its understanding of current PRC laws, rules and regulations and the M&A Rules, prior approval from the CSRC is not required under the M&A Rules for the listing and trading of our ADSs given that (i) our PRC subsidiaries were directly established by us as wholly foreign-owned enterprises and we have not acquired any equity interest or assets of a PRC domestic company owned by PRC companies or individuals as defined under the M&A Rules that are our beneficial owners after the effective date of the M&A Rules, and (ii) no provision in the M&A Rules clearly classifies the contractual arrangements as a type of transaction subject to the M&A Rules.

However, our PRC counsel has further advised us that uncertainties still exist as to how the M&A Rules will be interpreted and implemented and its opinions summarized above are subject to any new laws, rules and regulations or detailed implementations and interpretations in any form relating to the M&A Rules. If the CSRC or other PRC regulatory agencies subsequently determine that prior CSRC approval was required, we may face regulatory actions or other sanctions from the CSRC or other PRC regulatory agencies. See "Risk Factors—Risks Related to Our ADSs and This Offering—The approval of the CSRC may be required in connection with this offering under PRC law."

The M&A Rules also establish procedures and requirements that could make some acquisitions of PRC companies by foreign investors more time-consuming and complex, including requirements in some instances that MOFCOM be notified in advance of any change-of-control transaction in which a foreign investor takes control of a PRC domestic enterprise. In addition, the Rules on Implementation of Security Review System for the Merger and Acquisition of Domestic Enterprises by Foreign Investors issued by MOFCOM in 2011 specify that mergers and acquisitions by foreign investors that raise "national defense and security" concerns and mergers and acquisitions through which foreign investors may acquire de facto control over domestic enterprises that raise "national security" concerns are subject to strict review by MOFCOM, and prohibit any activities attempting to bypass such security review, including by structuring the transaction through a proxy or contractual control arrangement. See "Risk Factors—Risks Related to Doing Business in China—China's M&A Rules and certain other PRC regulations establish complex procedures for some acquisitions of PRC companies by foreign investors, which could make it more difficult for us to pursue growth through acquisitions in China."

Our officers are elected by and serve at the discretion of the board of directors. Our directors are not subject to a term of office and hold office until such time as they are removed from office by ordinary resolution of the shareholders or by the board. A director will be removed from office automatically if, among other things, the director (i) becomes bankrupt or makes any arrangement or composition with his creditors; or (ii) is found by our company to be or becomes of unsound mind.

[We have entered into employment agreements with each of our executive officers. Under these agreements, each of our executive officers is employed for a specified time period. We may terminate employment for cause, at any time, without advance notice or remuneration, for certain acts of the executive officer, such as conviction or plea of guilty to a felony or any crime involving moral turpitude, negligent or dishonest acts to our detriment, or misconduct or a failure to perform agreed duties. We may also terminate an executive officer's employment without cause upon three-month advance written notice. In such case of termination by us, we will provide severance payments to the executive officer as expressly required by applicable law of the jurisdiction where the executive officer is based. The executive officer may resign at any time with a three-month advance written notice.

Each executive officer has agreed to hold, both during and after the termination or expiry of his or her employment agreement, in strict confidence and not to use, except as required in the performance of his or her duties in connection with the employment or pursuant to applicable law, any of our confidential information or trade secrets, any confidential information or trade secrets of our clients or prospective clients, or the confidential or proprietary information of any third party received by us and for which we have confidential obligations. The executive officers have also agreed to disclose in confidence to us all inventions, designs and trade secrets which they conceive, develop or reduce to practice during the executive officer's employment with us and to assign all right, title and interest in them to us, and assist us in obtaining and enforcing patents, copyrights and other legal rights for these inventions, designs and trade secrets.

In addition, each executive officer has agreed to be bound by non-competition and non-solicitation restrictions during the term of his or her employment and typically for one year following the last date of employment. Specifically, each executive officer has agreed not to (i) approach our suppliers, clients, customers or contacts or other persons or entities introduced to the executive officer in his or her capacity as a representative of us for the purpose of doing business with such persons or entities that will harm our business relationships with these persons or entities; (ii) assume employment with or provide services to any of our competitors, or engage, whether as principal, partner, licensor or otherwise, any of our competitors, without our express consent; or (iii) seek directly or indirectly, to solicit the services of any of our employees who is employed by us on or after the date of the executive officer's termination, or in the year preceding such termination, without our express consent.

We have also entered into indemnification agreements with each of our directors and executive officers. Under these agreements, we agree to indemnify our directors and executive officers against certain liabilities and expenses incurred by such persons in connection with claims made by reason of their being a director or officer of our company.]

For the fiscal year ended December 31, 2017, we paid an aggregate of approximately RMB4.6 million (US$0.7 million) in cash to our executive officers, and we did not pay any compensation to our non-executive directors. We have not set aside or accrued any amount to provide pension, retirement or other similar benefits to our executive officers and directors. Our PRC subsidiaries and VIEs are required by law to make contributions equal to certain percentages of each employee's salary for his or

her pension insurance, medical insurance, unemployment insurance and other statutory benefits and a housing provident fund.

In November 2014, our board of directors approved a global share incentive plan, which we refer to as the Global Share Plan, to attract and retain the best available personnel, provide additional incentives to employees, directors and consultants and promote the success of our business. As of the date of this prospectus, the maximum aggregate number of ordinary shares which may be issued pursuant to all awards under the Global Share Plan is 19,880,315 ordinary shares, subject to amendment. As of the date of this prospectus, awards to purchase 19,409,209 ordinary shares under the Global Share Plan have been granted and outstanding, excluding awards that were forfeited or cancelled after the relevant grant dates.

Types of awards. The Global Share Plan permits the awards of options, restricted shares, restricted share units or any other type of awards approved by the plan administrator.

Plan administration. Our chairman of the board of directors or a committee of one or more members of the board of directors will administer the Global Share Plan. The chairman or the committee, as applicable, will determine the participants to receive awards, the type and number of awards to be granted to each participant, and the terms and conditions of each award grant. The full board of directors will conduct the general administration of the Global Share Plan if required by applicable laws and with respect to awards granted to the chairman of the board of directors, the committee members (if applicable), independent directors and executive officers of our company.

Award agreement. Awards granted under the Global Share Plan are evidenced by an award agreement that sets forth terms, conditions and limitations for each award, which may include the term of the award, the provisions applicable in the event of the grantee's employment or service terminates, and our authority to unilaterally or bilaterally amend, modify, suspend, cancel or rescind the award.

Eligibility. We may grant awards to our employees, directors and consultants of our company.

Vesting schedule. In general, the plan administrator determines the vesting schedule, which is specified in the relevant award agreement.

Exercise of options. The plan administrator determines the exercise price for each award, which is stated in the award agreement. The vested portion of option will expire if not exercised prior to the time as the plan administrator determines at the time of its grant. However, the maximum exercisable term is ten years from the date of a grant.

Transfer restrictions. Awards may not be transferred in any manner by the participant other than in accordance with the exceptions provided in the Global Share Plan or the relevant award agreement or otherwise determined by the plan administrator, such as transfers by will or the laws of descent and distribution.

Termination and amendment of the Global Share Plan. Unless terminated earlier, the Global Share Plan has a term of ten years. The plan administrator has the authority to terminate, amend or modify the plan. Except with respect to amendments made by the plan administrator, no termination, amendment or modification may adversely affect in any material way any awards previously granted pursuant to the Global Share Plan unless agreed by the participant.

The following table summarizes, as of the date of this prospectus, the options granted under the Global Share Plan to several of our executive officers, excluding awards that were forfeited or cancelled after the relevant grant dates.

We are a Cayman Islands company and our affairs are governed by our memorandum and articles of association and the Companies Law (2016 Revision) of the Cayman Islands, which we refer to as the Companies Law below.

All of our issued and outstanding ordinary and preferred shares are fully paid.

Immediately upon the completion of this offering, there will be ordinary shares outstanding, including a total of 142,913,505 ordinary shares resulting from the automatic conversion of all of our outstanding preferred shares, assuming the underwriters do not exercise the over-allotment option.

We expect to adopt, subject to the approval of our board of directors and shareholders, an amended and restated memorandum and articles of association, which will become effective and replace our current amended and restated memorandum and articles of association in its entirety immediately prior to the completion of this offering. The following are summaries of material provisions of the post-offering amended and restated memorandum and articles of association that we expect to adopt and of the Companies Law, insofar as they relate to the material terms of our ordinary shares.

Objects of Our Company. Under our post-offering amended and restated memorandum and articles of association, the objects of our company are unrestricted and we have the full power and authority to carry out any object not prohibited by the law of the Cayman Islands.

Ordinary Shares. Our ordinary shares are issued in registered form. We may not issue share to bearer. Our shareholders who are nonresidents of the Cayman Islands may freely hold and vote their shares.

Dividends. The holders of our ordinary shares are entitled to such dividends as may be declared by our board of directors. Our post-offering amended and restated articles of association provide that dividends may be declared and paid out of our profits, realized or unrealized, or from any reserve set aside from profits which our board of directors determine is no longer needed. Dividends may also be declared and paid out of share premium account or any other fund or account which can be authorized for this purpose in accordance with the Companies Law. Under the laws of the Cayman islands, our company may pay a dividend out of either profit or share premium account, provided that in no

circumstances may a dividend be paid if this would result in our company being unable to pay its debts as they fall due in the ordinary course of business.

Voting Rights. Our ordinary shares vote together as a single class on all matters submitted to a vote of our shareholders, except as may otherwise be required by law, or otherwise agreed in the memorandum and articles of association. In respect of matters requiring shareholders' vote, each ordinary share is entitled to one vote. Voting at any shareholders' meeting is by show of hands, and on a poll every shareholder shall have one vote for every share of which he is the holder. A poll shall be taken as the chairman directs, except on a poll demanded on the election of a chairman or on a question of adjournment.

A quorum required for a meeting of shareholders consists of one or more shareholders present in present or by proxy and holding not more than 50% of the outstanding shares entitled to vote in our company. Shareholders may be present in person or by proxy or, if the shareholder is a legal entity, by its duly authorized representative. Shareholders' meetings may be convened by our board of directors on its own initiative. Advance notice of at least ten days and no more than sixty days is required for the convening of our annual general shareholders' meeting and any other general shareholders' meeting.

An ordinary resolution to be passed at a meeting by the shareholders requires the affirmative vote of a simple majority of the votes attaching to the ordinary shares cast at a meeting. A special resolution requires the affirmative vote of no less than two-thirds of the votes cast attaching to the outstanding shares at a meeting, or with a written resolution signed by all members entitled to vote. A special resolution will be required for important matters such as a change of name or making changes that will affect the rights, preferences, privileges or powers of the preferred shareholders.

General Meetings of Shareholders. As a Cayman Islands exempted company, we are not obliged by the Companies Law to call shareholders' annual general meetings. Our post-offering memorandum and articles of association provide that we may (but are not obliged to) in each year hold a general meeting as our annual general meeting in which case we shall specify the meeting as such in the notices calling it, and the annual general meeting shall be held at such time and place as may be determined by our directors.

Shareholders' general meetings may be convened by a majority of our board of directors. Advance notice of at least seven days is required for the convening of our annual general shareholders' meeting (if any) and any other general meeting of our shareholders. A quorum required for any general meeting of shareholders consists of at least one shareholder present or by proxy, representing not less than one-third of all votes attaching to all of our shares in issue and entitled to vote.

The Companies Law provides shareholders with only limited rights to requisition a general meeting, and does not provide shareholders with any right to put any proposal before a general meeting. However, these rights may be provided in a company's articles of association. Our post-offering memorandum and articles of association provide that upon the requisition of shareholders representing in aggregate not less than one-third of the votes attaching to the outstanding shares of our company entitled to vote at general meetings, our board will convene an extraordinary general meeting and put the resolutions so requisitioned to a vote at such meeting. However, our post-offering memorandum and articles of association do not provide our shareholders with any right to put any proposals before annual general meetings or extraordinary general meetings not called by such shareholders.

Transfer of Ordinary Shares. Subject to the restrictions set out below, any of our shareholders may transfer all or any of his or her ordinary shares by an instrument of transfer in writing, and shall be executed by or on behalf of the transferor, and if the directors so requires, signed by the transferee.

Our board of directors may, in its absolute discretion, decline to register any transfer of any ordinary share which is not fully paid up or on which we have a lien. Our board of directors may also decline to register any transfer of any ordinary share unless:

If our directors refuse to register a transfer they shall, within three months after the date on which the instrument of transfer was lodged, send to each of the transferor and the transferee notice of such refusal.

The registration of transfers may, after compliance with any notice required of the [New York Stock Exchange/Nasdaq Global Select Market], be suspended and the register closed at such times and for such periods as our board of directors may from time to time determine, provided, however, that the registration of transfers shall not be suspended nor the register closed for more than 30 days in any year as our board may determine.

Liquidation. On the winding up of our company, if the assets available for distribution amongst our shareholders shall be more than sufficient to repay the whole of the share capital at the commencement of the winding up, the surplus shall be distributed amongst our shareholders in proportion to the par value of the shares held by them at the commencement of the winding up, subject to a deduction from those shares in respect of which there are monies due, of all monies payable to our company for unpaid calls or otherwise. If our assets available for distribution are insufficient to repay all of the paid-up capital, the assets will be distributed so that the losses are borne by our shareholders in proportion to the par value of the shares held by them.

Calls on Shares and Forfeiture of Shares. Our board of directors may from time to time make calls upon shareholders for any amounts unpaid on their shares in a notice served to such shareholders at least 14 days prior to the specified time and place of payment. The shares that have been called upon and remain unpaid are subject to forfeiture.

Redemption, Repurchase and Surrender of Shares. We may issue shares on terms that such shares are subject to redemption, at our option or at the option of the holders of these shares, on such terms and in such manner as may be determined by our board of directors. Our Company may also repurchase any of our shares on such terms and in such manner as have been approved by our board of directors or by an ordinary resolution of our shareholders. Under the Companies Law, the redemption or repurchase of any share may be paid out of our Company's profits or out of the proceeds of a new issue of shares made for the purpose of such redemption or repurchase, or out of capital (including share premium account and capital redemption reserve) if our company can, immediately following such payment, pay its debts as they fall due in the ordinary course of business. In addition, under the Companies Law no such share may be redeemed or repurchased (a) unless it is fully paid up, (b) if such redemption or repurchase would result in there being no shares outstanding or (c) if the company has commenced liquidation. In addition, our company may accept the surrender of any fully paid share for no consideration.

Variations of Rights of Shares. If at any time, out share capital is divided into different classes or series of shares, the rights attached to any class or series of shares (unless otherwise provided by the terms of issue of the shares of that class or series), whether or not our company is being wound-up, may be varied with the consent in writing of all the holders of the issued shares of that class or series or with the sanction of a resolution passed by a majority of the votes cast at a separate meeting of the holders of the shares of the class or series. The rights conferred upon the holders of the shares of any class issued shall not, unless otherwise expressly provided by the terms of issue of the shares of that class, be deemed to be varied by the creation or issue of further shares ranking pari passu with such existing class of shares.

Issuance of Additional Shares. Our post-offering amended and restated memorandum of association authorizes our board of directors to issue additional ordinary shares from time to time as our board of directors shall determine, to the extent of available authorized but unissued shares.

Our post-offering amended and restated memorandum of association also authorizes our board of directors to establish from time to time one or more series of preference shares and to determine, with respect to any series of preference shares, the terms and rights of that series, including:

Our board of directors may issue preference shares without action by our shareholders to the extent authorized but unissued. Issuance of these shares may dilute the voting power of holders of ordinary shares.

Inspection of Books and Records. Holders of our ordinary shares will have no general right under Cayman Islands law to inspect or obtain copies of our list of shareholders or our corporate records. However, we will provide our shareholders with annual audited financial statements. See "Where You Can Find Additional Information."

Anti-Takeover Provisions. Some provisions of our post-offering memorandum and articles of association may discourage, delay or prevent a change of control of our company or management that shareholders may consider favorable, including provisions that:

However, under Cayman Islands law, our directors may only exercise the rights and powers granted to them under our post-offering memorandum and articles of association for a proper purpose and for what they believe in good faith to be in the best interests of our company.

Exempted Company. We are an exempted company with limited liability under the Companies Law. The Companies Law distinguishes between ordinary resident companies and exempted companies. Any company that is registered in the Cayman Islands but conducts business mainly outside of the Cayman Islands may apply to be registered as an exempted company. The requirements for an exempted company are essentially the same as for an ordinary company except that an exempted company:

"Limited liability" means that the liability of each shareholder is limited to the amount unpaid by the shareholder on the shares of the company.]

The Companies Law is modeled after that of England but does not follow recent English statutory enactments and differs from laws applicable to U.S. corporations and their shareholders. Set forth below is a summary of the significant differences between the provisions of the Companies Law applicable to us and the laws applicable to companies incorporated in the United States and their shareholders.

Mergers and Similar Arrangements. The Companies Law permits mergers and consolidations between Cayman Islands companies and between Cayman Islands companies and non-Cayman Islands companies. For these purposes, (a) "merger" means the merging of two or more constituent companies and the vesting of their undertaking, property and liabilities in one of such companies as the surviving company, and (b) a "consolidation" means the combination of two or more constituent companies into a consolidated company and the vesting of the undertaking, property and liabilities of such companies to the consolidated company. In order to effect such a merger or consolidation, the directors of each constituent company must approve a written plan of merger or consolidation, which must then be authorized by (a) a special resolution of the shareholders of each constituent company, and (b) such other authorization, if any, as may be specified in such constituent company's articles of association. The plan must be filed with the Registrar of Companies of the Cayman Islands together with a declaration as to the solvency of the consolidated or surviving company, a list of the assets and liabilities of each constituent company and an undertaking that a copy of the certificate of merger or consolidation will be given to the members and creditors of each constituent company and that notification of the merger or consolidation will be published in the Cayman Islands Gazette. Court approval is not required for a merger or consolidation which is effected in compliance with these statutory procedures.

A merger between a Cayman parent company and its Cayman subsidiary or subsidiaries does not require authorization by a resolution of shareholders of that Cayman subsidiary if a copy of the plan of merger is given to every member of that Cayman subsidiary to be merged unless that member agrees otherwise. For this purpose a company is a "parent" of a subsidiary if it holds issued shares that together represent at least ninety percent (90%) of the votes at a general meeting of the subsidiary.

The consent of each holder of a fixed or floating security interest over a constituent company is required unless this requirement is waived by a court in the Cayman Islands.

Save in certain limited circumstances, a shareholder of a Cayman constituent company who dissents from the merger or consolidation is entitled to payment of the fair value of his shares (which, if not agreed between the parties, will be determined by the Cayman Islands court) upon dissenting to

the merger or consolidation, provide the dissenting shareholder complies strictly with the procedures set out in the Companies Law. The exercise of dissenter rights will preclude the exercise by the dissenting shareholder of any other rights to which he or she might otherwise be entitled by virtue of holding shares, save for the right to seek relief on the grounds that the merger or consolidation is void or unlawful.

Separate from the statutory provisions relating to mergers and consolidations, the Companies Law also contains statutory provisions that facilitate the reconstruction and amalgamation of companies by way of schemes of arrangement, provided that the arrangement is approved by a majority in number of each class of shareholders and creditors with whom the arrangement is to be made, and who must in addition represent three-fourths in value of each such class of shareholders or creditors, as the case may be, that are present and voting either in person or by proxy at a meeting, or meetings, convened for that purpose. The convening of the meetings and subsequently the arrangement must be sanctioned by the Grand Court of the Cayman Islands. While a dissenting shareholder has the right to express to the court the view that the transaction ought not to be approved, the court can be expected to approve the arrangement if it determines that:

The Companies Law also contains a statutory power of compulsory acquisition which may facilitate the "squeeze out" of dissentient minority shareholder upon a tender offer. When a tender offer is made and accepted by holders of 90% of the shares affected within four months, the offeror may, within a two-month period commencing on the expiration of such four month period, require the holders of the remaining shares to transfer such shares to the offeror on the terms of the offer. An objection can be made to the Grand Court of the Cayman Islands but this is unlikely to succeed in the case of an offer which has been so approved unless there is evidence of fraud, bad faith or collusion.

If an arrangement and reconstruction is thus approved, or if a tender offer is made and accepted, a dissenting shareholder would have no rights comparable to appraisal rights, save that objectors to a takeover offer may apply to the Grand Court of the Cayman Islands for various orders that the Grand Court of the Cayman Islands has a broad discretion to make, which would otherwise ordinarily be available to dissenting shareholders of Delaware corporations, providing rights to receive payment in cash for the judicially determined value of the shares.

Shareholders' Suits. In principle, we will normally be the proper plaintiff and as a general rule a derivative action may not be brought by a minority shareholder. However, based on English authorities, which would in all likelihood be of persuasive authority in the Cayman Islands, there are exceptions to the foregoing principle, including when:

Indemnification of Directors and Executive Officers and Limitation of Liability. Cayman Islands law does not limit the extent to which a company's memorandum and articles of association may provide for indemnification of officers and directors, except to the extent any such provision may be held by the Cayman Islands courts to be contrary to public policy, such as to provide indemnification against civil fraud or the consequences of committing a crime. Our post-offering amended and restated memorandum and articles of association permit indemnification of officers and directors for losses, damages, costs and expenses incurred in their capacities as such unless such losses or damages arise from dishonesty or fraud of such directors or officers. This standard of conduct is generally the same as permitted under the Delaware General Corporation Law for a Delaware corporation.

In addition, we have entered into indemnification agreements with our directors and executive officers that provide such persons with additional indemnification beyond that provided in our post-offering amended and restated memorandum and articles of association.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers or persons controlling us under the foregoing provisions, we have been informed that in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Directors' Fiduciary Duties. Under Delaware corporate law, a director of a Delaware corporation has a fiduciary duty to the corporation and its shareholders. This duty has two components: the duty of care and the duty of loyalty. The duty of care requires that a director act in good faith, with the care that an ordinarily prudent person would exercise under similar circumstances. Under this duty, a director must inform himself of, and disclose to shareholders, all material information reasonably available regarding a significant transaction. The duty of loyalty requires that a director acts in a manner he reasonably believes to be in the best interests of the corporation. He must not use his corporate position for personal gain or advantage. This duty prohibits self-dealing by a director and mandates that the best interest of the corporation and its shareholders take precedence over any interest possessed by a director, officer or controlling shareholder and not shared by the shareholders generally. In general, actions of a director are presumed to have been made on an informed basis, in good faith and in the honest belief that the action taken was in the best interests of the corporation. However, this presumption may be rebutted by evidence of a breach of one of the fiduciary duties. Should such evidence be presented concerning a transaction by a director, the director must prove the procedural fairness of the transaction, and that the transaction was of fair value to the corporation.

As a matter of Cayman Islands law, a director of a Cayman Islands company is in the position of a fiduciary with respect to the company and therefore it is considered that he owes the following duties to the company—a duty to act bona fide in the best interests of the company, a duty not to make a profit based on his position as director (unless the company permits him to do so) and a duty not to put himself in a position where the interests of the company conflict with his personal interest or his duty to a third party. A director of a Cayman Islands company owes to the company a duty to act with skill and care. It was previously considered that a director need not exhibit in the performance of his duties a greater degree of skill than may reasonably be expected from a person of his knowledge and experience. However, English and Commonwealth courts have moved towards an objective standard with regard to the required skill and care and these authorities are likely to be followed in the Cayman Islands.

Shareholder Action by Written Consent. Under the Delaware General Corporation Law, a corporation may eliminate the right of shareholders to act by written consent by amendment to its certificate of incorporation. Cayman Islands law and our post-offering amended and restated articles of association provide that shareholders may approve corporate matters by way of a unanimous written resolution signed by or on behalf of each shareholder who would have been entitled to vote on such matter at a general meeting without a meeting being held.

Shareholder Proposals. Under the Delaware General Corporation Law, a shareholder has the right to put any proposal before the annual meeting of shareholders, provided it complies with the notice provisions in the governing documents. A special meeting may be called by the board of directors or any other person authorized to do so in the governing documents, but shareholders may be precluded from calling special meetings.

The Companies Law provide shareholders with only limited rights to requisition a general meeting, and does not provide shareholders with any right to put any proposal before a general meeting. However, these rights may be provided in a company's articles of association. Our post-offering amended and restated articles of association allow our shareholders holding in aggregate not less than one-third of all votes attaching to the outstanding shares of our company entitled to vote at general meetings to requisition an extraordinary general meeting of our shareholders, in which case our board is obliged to convene an extraordinary general meeting and to put the resolutions so requisitioned to a vote at such meeting. Other than this right to requisition a shareholders' meeting, our post-offering amended and restated articles of association do not provide our shareholders with any other right to put proposals before annual general meetings or extraordinary general meetings. As an exempted Cayman Islands company, we are not obliged by law to call shareholders' annual general meetings.

Cumulative Voting. Under the Delaware General Corporation Law, cumulative voting for elections of directors is not permitted unless the corporation's certificate of incorporation specifically provides for it. Cumulative voting potentially facilitates the representation of minority shareholders on a board of directors since it permits the minority shareholder to cast all the votes to which the shareholder is entitled on a single director, which increases the shareholder's voting power with respect to electing such director. There are no prohibitions in relation to cumulative voting under the laws of the Cayman Islands but our post-offering amended and restated articles of association do not provide for cumulative voting. As a result, our shareholders are not afforded any less protections or rights on this issue than shareholders of a Delaware corporation.

Removal of Directors. Under the Delaware General Corporation Law, a director of a corporation with a classified board may be removed only for cause with the approval of a majority of the outstanding shares entitled to vote, unless the certificate of incorporation provides otherwise. Under our post-offering amended and restated articles of association, directors may be removed with or without cause, by an ordinary resolution of our shareholders.

Transactions with Interested Shareholders. The Delaware General Corporation Law contains a business combination statute applicable to Delaware corporations whereby, unless the corporation has specifically elected not to be governed by such statute by amendment to its certificate of incorporation, it is prohibited from engaging in certain business combinations with an "interested shareholder" for three years following the date that such person becomes an interested shareholder. An interested shareholder generally is a person or a group who or which owns or owned 15% or more of the target's outstanding voting share within the past three years. This has the effect of limiting the ability of a potential acquirer to make a two-tiered bid for the target in which all shareholders would not be treated equally. The statute does not apply if, among other things, prior to the date on which such shareholder becomes an interested shareholder, the board of directors approves either the business combination or the transaction which resulted in the person becoming an interested shareholder. This encourages any potential acquirer of a Delaware corporation to negotiate the terms of any acquisition transaction with the target's board of directors.

Cayman Islands law has no comparable statute. As a result, we cannot avail ourselves of the types of protections afforded by the Delaware business combination statute. However, although Cayman Islands law does not regulate transactions between a company and its significant shareholders, it does provide that such transactions must be entered into bona fide in the best interests of the company and not with the effect of constituting a fraud on the minority shareholders.

Dissolution; Winding up. Under the Delaware General Corporation Law, unless the board of directors approves the proposal to dissolve, dissolution must be approved by shareholders holding 100% of the total voting power of the corporation. Only if the dissolution is initiated by the board of directors may it be approved by a simple majority of the corporation's outstanding shares. Delaware law allows a Delaware corporation to include in its certificate of incorporation a supermajority voting requirement in connection with dissolutions initiated by the board.

Under Cayman Islands law, a company may be wound up by either an order of the courts of the Cayman Islands or by a special resolution of its members or, if the company is unable to pay its debts as they fall due, by an ordinary resolution of its members. The court has authority to order winding up in a number of specified circumstances including where it is, in the opinion of the court, just and equitable to do so. Under the Companies Law and our post-offering amended and restated articles of association, our company may be dissolved, liquidated or wound up by a special resolution of our shareholders.

Variation of Rights of Shares. Under the Delaware General Corporation Law, a corporation may vary the rights of a class of shares with the approval of a majority of the outstanding shares of such class, unless the certificate of incorporation provides otherwise. Under Cayman Islands law and our post-offering amended and restated articles of association, if our share capital is divided into more than one class of shares, we may vary the rights attached to any class with the written consent of the holders of a majority of the issued shares of that class or with the sanction of a special resolution passed at a general meeting of the holders of the shares of that class.

Amendment of Governing Documents. Under the Delaware General Corporation Law, a corporation's governing documents may be amended with the approval of a majority of the outstanding shares entitled to vote, unless the certificate of incorporation provides otherwise. As permitted by Cayman Islands law, our post-offering amended and restated memorandum and articles of association may only be amended with a special resolution of our shareholders.

Rights of Non-resident or Foreign Shareholders. There are no limitations imposed by our post-offering amended and restated memorandum and articles of association on the rights of non-resident or foreign shareholders to hold or exercise voting rights on our shares. In addition, there are no provisions in our post-offering amended and restated memorandum and articles of association governing the ownership threshold above which shareholder ownership must be disclosed.

On July 15, 2015 and May 10, 2016, we issued an aggregate of 5,000,000 Class A ordinary shares to Saber Lily Limited, a business company limited by shares incorporated in British Virgin Islands wholly owned by our director and chief operating officer, Ms. Ni Li, for her past and future services to us. 500,000 of these shares were subsequently repurchased by us.

On the same day, we also issued a total of 13,759,564 Series D2 preferred shares to CMC Beacon Holdings Limited, Tencent Mobility Limited and Cheerford Limited for an aggregate consideration of US$100.0 million.

We have granted options to purchase our ordinary shares to certain of our directors, executive officers and employees. See "Management—Global Share Incentive Plan."

We entered into our shareholders agreement on April 1, 2017 with our shareholders, which consist of holders of ordinary shares and preferred shares.

The shareholders agreement provides for certain special rights, including right of first refusal, co-sale rights, preemptive rights and contains provisions governing the board of directors and other corporate governance matters. Those special rights, as well as the corporate governance provisions, will automatically terminate upon the completion of a qualified initial public offering.

Pursuant to our shareholders agreement dated April 1, 2017, we have granted certain registration rights to our shareholders. Set forth below is a description of the registration rights granted under the agreement.

Demand Registration Rights. Holders holding at least 10% or more of the issued and outstanding registrable securities (on an as converted basis) held by the preferred shareholders, the Class D ordinary shareholders, Class C ordinary shareholders or Class B ordinary shareholders have the right to demand in writing that we file a registration statement covering the registration of at least 25% of their registrable securities. We have the right to defer filing of a registration statement for a period of not more than 90 days if our board of directors determines in good faith that filing of a registration statement in the near future will be materially detrimental to us or our shareholders, but we cannot exercise the deferral right more than once for more than once during any twelve-month period and cannot register any other securities during such period. We are not obligated to effect more than three

demand registrations. Further, if the registrable securities are offered by means of an underwritten offering, and the managing underwriter advises us that marketing factors require a limitation of the number of securities to be underwritten, the underwriters may decide to exclude (i) all of the registrable securities in our initial public offering, or (ii) up to 75% of the registrable securities and the number of the registrable securities will be allocated among the holders on a pro rata basis according to the number of registrable securities then outstanding held by each holder requesting registration, provided that all other equity securities are first excluded.

Registration on Form F-3 or Form S-3. Any holder may request us to file a registration statement on Form F-3 or Form S-3 if we qualify for registration on Form F-3 or Form S-3. The holders are entitled to an unlimited number of registrations on Form F-3 or Form S-3 so long as such registration offerings are in excess of US$500,000. We, however, are not obligated to consummate a registration if we have consummated two registrations within any twelve month period. We have the right to defer filing of a registration statement for a period of not more than 90 days if our board of directors determines in good faith that filing of a registration statement in the near future will be materially detrimental to us or our shareholders, but we cannot exercise the deferral right more than once for more than once during any twelve-month period and cannot register any other securities during such period.

Piggyback Registration Rights. If we propose to register for a public offering or our securities other than relating to any share incentive plan or a corporate reorganization, we must offer holders of our registrable securities an opportunity to be included in such registration. If the underwriters advise in writing that market factors require a limitation of the number of registrable securities to be underwritten, the underwriters may decide to exclude (i) all of the registrable securities in our initial public offering, or (ii) up to 75% of the registrable securities and the number of the registrable securities will be allocated among the holders on a pro rata basis according to the number of registrable securities then outstanding held by each holder requesting registration, provided that all other equity securities are first excluded (except for securities sold for the account of our company).

Expenses of Registration. We will bear all registration expenses, other than the underwriting discounts and selling commissions applicable to the sale of registrable securities, incurred in connection with registrations, filings or qualification pursuant to the shareholders agreement.

Termination of Obligations. We have no obligation to effect any demand, piggyback or Form F-3 or Form S-3 registration upon the later of (i) the fifth anniversary from the date of closing of a QIPO as defined in the shareholders agreement, and (ii) with respect to any holder, the date following a QIPO on which such holder holds less than 1% of the equity securities of our company and all registrable securities may be sold under Rule 144 of the Securities Act in any 90-day period.

, as depositary will issue the ADSs which you will be entitled to receive in this offering. Each ADS will represent an ownership interest in ordinary shares which we will deposit with the custodian, as agent of the depositary, under the deposit agreement among ourselves, the depositary and yourself as an ADR holder. In the future, each ADS will also represent any securities, cash or other property deposited with the depositary but which they have not distributed directly to you. Unless specifically requested by you, all ADSs will be issued on the books of our depositary in book-entry form and periodic statements will be mailed to you which reflect your ownership interest in such ADSs. In our description, references to American depositary receipts or ADRs shall include the statements you will receive which reflect your ownership of ADSs.

You may hold ADSs either directly or indirectly through your broker or other financial institution. If you hold ADSs directly, by having an ADS registered in your name on the books of the depositary, you are an ADR holder. This description assumes you hold your ADSs directly. If you hold the ADSs through your broker or financial institution nominee, you must rely on the procedures of such broker or financial institution to assert the rights of an ADR holder described in this section. You should consult with your broker or financial institution to find out what those procedures are.

As an ADR holder, we will not treat you as a shareholder of ours and you will not have any shareholder rights. Cayman Islands law governs shareholder rights. Because the depositary or its nominee will be the shareholder of record for the shares represented by all outstanding ADSs, shareholder rights rest with such record holder. Your rights are those of an ADR holder. Such rights derive from the terms of the deposit agreement to be entered into among us, the depositary and all registered holders from time to time of ADSs issued under the deposit agreement. The obligations of the depositary and its agents are also set out in the deposit agreement. Because the depositary or its nominee will actually be the registered owner of the shares, you must rely on it to exercise the rights of a shareholder on your behalf. The deposit agreement and the ADSs are governed by New York law.

The following is a summary of what we believe to be the material terms of the deposit agreement. Notwithstanding this, because it is a summary, it may not contain all the information that you may otherwise deem important. For more complete information, you should read the entire deposit agreement and the form of ADR which contains the terms of your ADSs. You can read a copy of the deposit agreement which is filed as an exhibit to the registration statement of which this prospectus forms apart. You may also obtain a copy of the deposit agreement at the SEC's Public Reference Room which is located at 100 F Street, NE, Washington, DC 20549. You may obtain information on the operation of the Public Reference Room by calling the SEC at 1-800-732-0330. You may also find the registration statement and the attached deposit agreement on the SEC's website at http://www.sec.gov.

How will I receive dividends and other distributions on the shares underlying my ADSs?

We may make various types of distributions with respect to our securities. The depositary has agreed that, to the extent practicable, it will pay to you the cash dividends or other distributions it or the custodian receives on shares or other deposited securities, after converting any cash received into U.S. dollars and, in all cases, making any necessary deductions provided for in the deposit agreement. You will receive these distributions in proportion to the number of underlying securities that your ADSs represent.

Except as stated below, the depositary will deliver such distributions to ADR holders in proportion to their interests in the following manner:

We have no obligation to file a registration statement under the Securities Act in order to make any rights available to ADR holders.

If the depositary determines that any distribution described above is not practicable with respect to any specific registered ADR holder, the depositary may choose any method of distribution that it deems practicable for such ADR holder, including the distribution of foreign currency, securities or property, or it may retain such items, without paying interest on or investing them, on behalf of the ADR holder as deposited securities, in which case the ADSs will also represent the retained items.

Any U.S. dollars will be distributed by checks drawn on a bank in the United States for whole dollars and cents. Fractional cents will be withheld without liability and dealt with by the depositary in accordance with its then current practices.

The depositary is not responsible if it decides that it is unlawful or impractical to make a distribution available to any ADR holders.

There can be no assurance that the depositary will be able to convert any currency at a specified exchange rate or sell any property, rights, shares or other securities at a specified price, nor that any of such transactions can be completed within a specified time period.

The depositary will issue ADSs if you or your broker deposit shares or evidence of rights to receive shares with the custodian and pay the fees and expenses owing to the depositary in connection with such issuance. In the case of the ADSs to be issued under this prospectus, we will arrange with the underwriters named herein to deposit such shares.

Shares deposited in the future with the custodian must be accompanied by certain delivery documentation and shall, at the time of such deposit, be registered in the name of , as depositary for the benefit of holders of ADRs or in such other name as the depositary shall direct.

The custodian will hold all deposited shares (including those being deposited by or on our behalf in connection with the offering to which this prospectus relates) for the account of the depositary. ADR holders thus have no direct ownership interest in the shares and only have such rights as are contained in the deposit agreement. The custodian will also hold any additional securities, property and cash received on or in substitution for the deposited shares. The deposited shares and any such additional items are referred to as "deposited securities".

Upon each deposit of shares, receipt of related delivery documentation and compliance with the other provisions of the deposit agreement, including the payment of the fees and charges of the depositary and any taxes or other fees or charges owing, the depositary will issue an ADR or ADRs in the name or upon the order of the person entitled thereto evidencing the number of ADSs to which such person is entitled. All of the ADSs issued will, unless specifically requested to the contrary, be part of the depositary's direct registration system, and a registered holder will receive periodic statements from the depositary which will show the number of ADSs registered in such holder's name. An ADR holder can request that the ADSs not be held through the depositary's direct registration system and that a certificated ADR be issued.

When you turn in your ADR certificate at the depositary's office, or when you provide proper instructions and documentation in the case of direct registration ADSs, the depositary will, upon payment of certain applicable fees, charges and taxes, deliver the underlying shares to you or upon your written order. At your risk, expense and request, the depositary may deliver deposited securities at such other place as you may request.

The depositary may only restrict the withdrawal of deposited securities in connection with:

This right of withdrawal may not be limited by any other provision of the deposit agreement.

The depositary may, after consultation with us if practicable, fix record dates for the determination of the registered ADR holders who will be entitled (or obligated, as the case may be):

If you are an ADR holder and the depositary asks you to provide it with voting instructions, you may instruct the depositary how to exercise the voting rights for the shares which underlie your ADSs. As soon as practicable after receiving notice of any meeting or solicitation of consents or proxies from us, the depositary will distribute to the registered ADR holders a notice stating such information as is contained in the voting materials received by the depositary and describing how you may instruct the depositary to exercise the voting rights for the shares which underlie your ADSs. For instructions to be valid, the depositary must receive them in the manner and on or before the date specified. No voting instructions may be deemed given to the depositary to give a discretionary proxy to a person designated by us if no instructions are received by the depositary from you on or before the response date established by the depositary. The depositary will try, as far as is practical, subject to the provisions of and governing the underlying shares or other deposited securities, to vote or to have its agents vote the shares or other deposited securities as you instruct. The depositary will only vote or attempt to vote as you instruct. The depositary will not itself exercise any voting discretion. Furthermore, neither the depositary nor its agents are responsible for any failure to carry out any voting instructions, for the manner in which any vote is cast or for the effect of any vote. Notwithstanding anything contained in the deposit agreement or any ADR, the depositary may, to the extent not prohibited by law or regulations, or by the requirements of the stock exchange on which the ADSs are listed, in lieu of distribution of the materials provided to the depositary in connection with any meeting of, or solicitation of consents or proxies from, holders of deposited securities, distribute to the registered holders of ADRs a notice that provides such holders with, or otherwise publicizes to such holders, instructions on how to retrieve such materials or receive such materials upon request (i.e., by reference to a website containing the materials for retrieval or a contact for requesting copies of the materials).

[Under our constituent documents the depositary would be able to provide us with voting instructions without having to personally attend meetings in person or by proxy. Such voting instructions may be provided to us via facsimile, email, mail, courier or other recognized form of delivery and we agree to accept any such delivery so long as it is timely received prior to the meeting. We will endeavor to provide the depositary with written notice of each meeting of shareholders promptly after determining the date of such meeting so as to enable it to solicit and receive voting instructions. In general, the depositary will require that voting instructions be received by the depositary no less than five business days prior to the date of each meeting of shareholders. Under the

post-offering memorandum and articles of association that we expect to adopt, the minimum notice period required to convene a general meeting is seven days. The depositary may not have sufficient time to solicit voting instructions, and it is possible that you, or persons who hold their ADSs through brokers, dealers or other third parties, will not have the opportunity to exercise a right to vote.]

Notwithstanding the above, we have advised the depositary that under the Cayman Islands law and our constituent documents, each as in effect as of the date of the deposit agreement, voting at any meeting of shareholders is by show of hands unless a poll is (before or on the declaration of the results of the show of hands) demanded. In the event that voting on any resolution or matter is conducted on a show of hands basis in accordance with our constituent documents, the depositary will refrain from voting and the voting instructions (or the deemed voting instructions, as set out above) received by the depositary from holders shall lapse. The depositary will not demand a poll or join in demanding a poll, whether or not requested to do so by holders of ADSs.

There is no guarantee that you will receive voting materials in time to instruct the depositary to vote and it is possible that you, or persons who hold their ADSs through brokers, dealers or other third parties, will not have the opportunity to exercise a right to vote.

The depositary will make available for inspection by ADR holders at the offices of the depositary and the custodian the deposit agreement, the provisions of or governing deposited securities, and any written communications from us which are both received by the custodian or its nominee as a holder of deposited securities and made generally available to the holders of deposited securities.

Additionally, if we make any written communications generally available to holders of our shares, and we furnish copies thereof (or English translations or summaries) to the depositary, it will distribute the same to registered ADR holders.

The depositary may charge each person to whom ADSs are issued, including, without limitation, issuances against deposits of shares, issuances in respect of share distributions, rights and other distributions, issuances pursuant to a stock dividend or stock split declared by us or issuances pursuant to a merger, exchange of securities or any other transaction or event affecting the ADSs or deposited securities, and each person surrendering ADSs for withdrawal of deposited securities or whose ADRs are cancelled or reduced for any other reason, US$5.00 for each 100 ADSs (or any portion thereof) issued, delivered, reduced, cancelled or surrendered, as the case may be. The depositary may sell (by public or private sale) sufficient securities and property received in respect of a share distribution, rights and/or other distribution prior to such deposit to pay such charge.

The following additional charges shall be incurred by the ADR holders, by any party depositing or withdrawing shares or by any party surrendering ADSs or to whom ADSs are issued (including, without limitation, issuance pursuant to a stock dividend or stock split declared by us or an exchange of stock regarding the ADRs or the deposited securities or a distribution of ADSs), whichever is applicable:

We will pay all other charges and expenses of the depositary and any agent of the depositary (except the custodian) pursuant to agreements from time to time between us and the depositary. The charges described above may be amended from time to time by agreement between us and the depositary.

Our depositary has agreed to reimburse us for certain expenses we incur that are related to establishment and maintenance of the ADR program, including investor relations expenses and exchange application and listing fees. Neither the depositary nor we can determine the exact amount to be made available to us because (i) the number of ADSs that will be issued and outstanding, (ii) the level of fees to be charged to holders of ADSs and (iii) our reimbursable expenses related to the ADR program are not known at this time. The depositary collects its fees for issuance and cancellation of ADSs directly from investors depositing shares or surrendering ADSs for the purpose of withdrawal or from intermediaries acting for them. The depositary collects fees for making distributions to investors by deducting those fees from the amounts distributed or by selling a portion of distributable property to pay the fees. The depositary may collect its annual fee for depositary services by deduction from cash distributions, or by directly billing investors, or by charging the book-entry system accounts of participants acting for them. The depositary will generally set off the amounts owing from distributions made to holders of ADSs. If, however, no distribution exists and payment owing is not timely received by the depositary, the depositary may refuse to provide any further services to holders that have not paid those fees and expenses owing until such fees and expenses have been paid. At the discretion of the depositary, all fees and charges owing under the deposit agreement are due in advance and/or when declared owing by the depositary.

ADR holders must pay any tax or other governmental charge payable by the custodian or the depositary on any ADS or ADR, deposited security or distribution. If an ADR holder owes any tax or other governmental charge, the depositary may (i) deduct the amount thereof from any cash distributions, or (ii) sell deposited securities (by public or private sale) and deduct the amount owing from the net proceeds of such sale. In either case the ADR holder remains liable for any shortfall. Additionally, if any taxes or other governmental charges (including any penalties and/or interest) shall become payable by or on behalf of the custodian or the depositary with respect to any ADR, any deposited securities represented by the ADSs evidenced thereby or any distribution thereon, including, without limitation, any PRC Enterprise Income Tax owing if the Circular Guoshuifa [2009] No. 82 issued by the SAT or any other circular, edict, order or ruling, as issued and as from time to time amended, is applied or otherwise, such tax or other governmental charge shall be paid by the holder thereof to the depositary. and by holding or having held an ADR the holder and all prior holders thereof, jointly and severally, agree to indemnify, defend and save harmless each of the depositary and its agents in respect thereof. If any tax or governmental charge is unpaid, the depositary may also refuse to effect any registration, registration of transfer, split-up or combination of deposited securities or withdrawal of deposited securities until such payment is made. If any tax or governmental charge is required to be withheld on any cash distribution, the depositary may deduct the amount required to be withheld from any cash distribution or, in the case of a non-cash distribution, sell the distributed property or securities (by public or private sale) to pay such taxes and distribute any remaining net proceeds to the ADR holders entitled thereto.

By holding an ADR or an interest therein, you will be agreeing to indemnify us, the depositary, its custodian and any of our or their respective directors, employees, agents and affiliates against, and hold each of them harmless from, any claims by any governmental authority with respect to taxes, additions to tax, penalties or interest arising out of any refund of taxes, reduced rate of withholding at source or other tax benefit obtained.

If we take certain actions that affect the deposited securities, including (i) any change in par value, split-up, consolidation, cancellation or other reclassification of deposited securities or (ii) any distributions not made to holders of ADRs or (iii) any recapitalization, reorganization, merger, consolidation, liquidation, receivership, bankruptcy or sale of all or substantially all of our assets, then the depositary may choose to:

If the depositary does not choose any of the above options, any of the cash, securities or other property it receives will constitute part of the deposited securities and each ADS will then represent a proportionate interest in such property.

We may agree with the depositary to amend the deposit agreement and the ADSs without your consent for any reason. ADR holders must be given at least [30] days' notice of any amendment that imposes or increases any fees or charges (other than stock transfer or other taxes and other governmental charges, transfer or registration fees, cable, telex or facsimile transmission costs, delivery costs or other such expenses), or otherwise prejudices any substantial existing right of ADR holders. Such notice need not describe in detail the specific amendments effectuated thereby, but must give ADR holders a means to access the text of such amendment. If an ADR holder continues to hold an ADR or ADRs after being so notified, such ADR holder is deemed to agree to such amendment and to be bound by the deposit agreement as so amended. Notwithstanding the foregoing, if any governmental body or regulatory body should adopt new laws, rules or regulations which would require amendment or supplement of the deposit agreement or the form of ADR to ensure compliance therewith, we and the depositary may amend or supplement the deposit agreement and the ADR at any time in accordance with such changed laws, rules or regulations, which amendment or supplement may take effect before a notice is given or within any other period of time as required for compliance. No amendment, however, will impair your right to surrender your ADSs and receive the underlying securities, except in order to comply with mandatory provisions of applicable law.

The depositary may, and shall at our written direction, terminate the deposit agreement and the ADRs by mailing notice of such termination to the registered holders of ADRs at least [30] days prior to the date fixed in such notice for such termination; provided, however, if the depositary shall have (i) resigned as depositary under the deposit agreement, notice of such termination by the depositary shall not be provided to registered holders unless a successor depositary shall not be operating under the deposit agreement within [45] days of the date of such resignation, and (ii) been removed as depositary under the deposit agreement, notice of such termination by the depositary shall not be provided to registered holders of ADRs unless a successor depositary shall not be operating under the deposit agreement on the [90]th day after our notice of removal was first provided to the depositary. After termination, the depositary's only responsibility will be (i) to deliver deposited securities to ADR holders who surrender their ADRs, and (ii) to hold or sell distributions received on deposited securities. As soon as practicable after the expiration of six months from the termination date, the depositary will sell the deposited securities which remain and hold the net proceeds of such sales (as long as it may lawfully do so), without liability for interest, in trust for the ADR holders who have not yet surrendered their ADRs. After making such sale, the depositary shall have no obligations except to account for such proceeds and other cash.

Prior to the issue, registration, registration of transfer, split-up, combination, or cancellation of any ADRs, or the delivery of any distribution in respect thereof, and from time to time, we or the depositary or its custodian may require:

The issuance of ADRs, the acceptance of deposits of shares, the registration, registration of transfer, split-up or combination of ADRs or the withdrawal of shares, may be suspended, generally or in particular instances, when the ADR register or any register for deposited securities is closed or when any such action is deemed advisable by the depositary; provided that the ability to withdrawal shares may only be limited under the following circumstances: (i) temporary delays caused by closing transfer books of the depositary or our transfer books or the deposit of shares in connection with voting at a shareholders' meeting, or the payment of dividends, (ii) the payment of fees, taxes, and similar charges, and (iii) compliance with any laws or governmental regulations relating to ADRs or to the withdrawal of deposited securities.

The deposit agreement expressly limits the obligations and liability of the depositary, ourselves and our respective agents. Neither we nor the depositary nor any such agent will be liable if:

Neither the depositary nor its agents have any obligation to appear in, prosecute or defend any action, suit or other proceeding in respect of any deposited securities or the ADRs. We and our agents shall only be obligated to appear in, prosecute or defend any action, suit or other proceeding in respect of any deposited securities or the ADRs, which in our opinion may involve us in expense or liability, if indemnity satisfactory to us against all expense (including fees and disbursements of counsel) and liability is furnished as often as may be required. The depositary and its agents may fully respond to any and all demands or requests for information maintained by or on its behalf in connection with the deposit agreement, any registered holder or holders of ADRs, any ADRs or otherwise related to the deposit agreement or ADRs to the extent such information is requested or required by or pursuant to any lawful authority, including without limitation laws, rules, regulations, administrative or judicial process, banking, securities or other regulators. The depositary shall not be liable for the acts or

omissions made by any securities depository, clearing agency or settlement system in connection with or arising out of book-entry settlement of deposited securities or otherwise. Furthermore, the depositary shall not be responsible for, and shall incur no liability in connection with or arising from, the insolvency of any custodian that is not a branch or affiliate of . The depositary and the custodian(s) may use third party delivery services and providers of information regarding matters such as pricing, proxy voting, corporate actions, class action litigation and other services in connection with the ADRs and the deposit agreement, and use local agents to provide extraordinary services such as attendance at annual meetings of issuers of securities. Although the depositary and the custodian will use reasonable care (and cause their agents to use reasonable care) in the selection and retention of such third party providers and local agents, they will not be responsible for any errors or omissions made by them in providing the relevant information or services.

Additionally, none of us, the depositary or the custodian shall be liable for the failure by any registered holder of ADRs or beneficial owner therein to obtain the benefits of credits on the basis of non-U.S. tax paid against such holder's or beneficial owner's income tax liability. Neither we nor the depositary shall incur any liability for any tax consequences that may be incurred by holders or beneficial owners on account of their ownership of ADRs or ADSs.

Neither the depositary nor its agents will be responsible for any failure to carry out any instructions to vote any of the deposited securities, for the manner in which any such vote is cast or for the effect of any such vote. Neither the depositary nor any of its agents shall be liable to registered holders of ADRs or beneficial owners of interests in ADSs for any indirect, special, punitive or consequential damages (including, without limitation, lost profits) of any form incurred by any person or entity, whether or not foreseeable and regardless of the type of action in which such a claim may be brought.

In the deposit agreement each party thereto (including, for avoidance of doubt, each holder and beneficial owner and/or holder of interests in ADRs) irrevocably waives, to the fullest extent permitted by applicable law, any right it may have to a trial by jury in any suit, action or proceeding against the depositary and/or the company directly or indirectly arising out of or relating to the shares or other deposited securities, the ADSs or the ADRs, the deposit agreement or any transaction contemplated therein, or the breach thereof (whether based on contract, tort, common law or any other theory).

To the extent that the provisions of or governing any deposited securities may require disclosure of or impose limits on beneficial or other ownership of deposited securities, other shares and other securities and may provide for blocking transfer, voting or other rights to enforce such disclosure or limits, you agree to comply with all such disclosure requirements and ownership limitations and to comply with any reasonable instructions we may provide in respect thereof. We reserve the right to instruct you to deliver your ADSs for cancellation and withdrawal of the deposited securities so as to permit us to deal with you directly as a holder of shares and, by holding an ADS or an interest therein, you will be agreeing to comply with such instructions.

The depositary or its agent will maintain a register for the registration, registration of transfer, combination and split-up of ADRs, which register shall include the depositary's direct registration system. Registered holders of ADRs may inspect such records at the depositary's office at all reasonable times, but solely for the purpose of communicating with other holders in the interest of the business of our company or a matter relating to the deposit agreement. Such register may be closed from time to time, when deemed expedient by the depositary.

In its capacity as depositary, the depositary shall not lend shares or ADSs; provided, however, that the depositary may issue ADSs prior to the receipt of shares (each such transaction a "pre-release"). The depositary may receive ADSs in lieu of shares (which ADSs will promptly be canceled by the depositary upon receipt by the depositary). Each such pre-release will be subject to a written agreement whereby the person or entity (the "applicant") to whom ADSs are to be delivered (a) represents that at the time of the pre-release the applicant or its customer owns the shares that are to be delivered by the applicant under such pre-release, (b) agrees to indicate the depositary as owner of such shares in its records and to hold such shares in trust for the depositary until such shares are delivered to the depositary or the custodian, (c) unconditionally guarantees to deliver to the depositary or the custodian, as applicable, such shares, and (d) agrees to any additional restrictions or requirements that the depositary deems appropriate. Each such pre-release will be at all times fully collateralized with cash, U.S. government securities or such other collateral as the depositary deems appropriate, terminable by the depositary on not more than five (5) business days' notice and subject to such further indemnities and credit regulations as the depositary deems appropriate. The depositary will normally limit the number of ADSs involved in such pre-release at any one time to thirty percent (30%) of the ADSs outstanding (without giving effect to pre-released ADSs outstanding), provided, however, that the depositary reserves the right to change or disregard such limit from time to time as it deems appropriate. The depositary may also set limits with respect to the number of ADSs involved in pre-release with any one person on a case-by-case basis as it deems appropriate. The depositary may retain for its own account any compensation received by it in conjunction with the foregoing. Collateral provided in connection with pre-release transactions, but not the earnings thereon, shall be held for the benefit of the registered holders of ADRs (other than the applicant).

In the deposit agreement, each registered holder of ADRs and each person holding an interest in ADSs, upon acceptance of any ADSs (or any interest therein) issued in accordance with the terms and conditions of the deposit agreement will be deemed for all purposes to:

The deposit agreement and the ADRs shall be governed by and construed in accordance with the laws of the State of New York. In the deposit agreement, we have submitted to the jurisdiction of the courts of the State of New York and appointed an agent for service of process on our behalf. Notwithstanding the foregoing, any action based on the deposit agreement or the transactions contemplated thereby may be instituted by the depositary and holders in any competent court in the Cayman Islands, Hong Kong, China and/or the United States or through the commencement of an English language arbitration either in New York, New York in accordance with the Commercial Arbitration Rules of the American Arbitration Association or in Hong Kong following the arbitration rules of the United Nations Commission on International Trade Law (UNCITRAL).]

Upon completion of this offering, we will have ADSs outstanding, representing approximately % of our outstanding ordinary shares, assuming the underwriters do not exercise their over-allotment option. All of the ADSs sold in this offering will be freely transferable by persons other than by our "affiliates" without restriction or further registration under the Securities Act. Sales of substantial amounts of our ADSs in the public market could adversely affect prevailing market prices of our ADSs. Prior to this offering, there has been no public market for our ordinary shares or the ADSs. We intend to apply to list the ADSs on the [New York Stock Exchange/Nasdaq Global Select Market], but we cannot assure you that a regular trading market will develop in the ADSs. We do not expect that a trading market will develop for our ordinary shares not represented by the ADSs.

We have agreed, for a period of 180 days after the date of this prospectus, [not to offer, sell, contract to sell, pledge, grant any option to purchase, make any short sale, lend or otherwise dispose of, except in this offering, any of our ordinary shares or ADSs or securities that are substantially similar to our ordinary shares or ADSs, including but not limited to any options or warrants to purchase our ordinary shares, ADSs or any securities that are convertible into or exchangeable for, or that represent the right to receive, our ordinary shares, ADSs or any such substantially similar securities (other than pursuant to employee stock option plans existing on, or upon the conversion or exchange of convertible or exchangeable securities outstanding as of, the date such lock-up agreement was executed),] without the prior written consent of the representatives of the underwriters.

Furthermore, each of our directors, executive officers and existing shareholders [and certain option holders] has also entered into a similar lock-up agreement for a period of 180 days from the date of this prospectus, subject to certain exceptions, with respect to our ordinary shares, ADSs and securities that are substantially similar to our ordinary shares or ADSs. [These restrictions also apply to any ADSs acquired by our directors and executive officers in the offering pursuant to the directed ADS program, if any.] These parties collectively own [all of] our outstanding ordinary shares, without giving effect to this offering.

The restrictions described in the preceding paragraphs will be automatically extended under certain circumstances. See "Underwriting."

Other than this offering, we are not aware of any plans by any significant shareholders to dispose of significant numbers of our ADSs or ordinary shares. However, one or more existing shareholders or owners of securities convertible or exchangeable into or exercisable for our ADSs or ordinary shares may dispose of significant numbers of our ADSs or ordinary shares in the future. We cannot predict what effect, if any, future sales of our ADSs or ordinary shares, or the availability of ADSs or ordinary shares for future sale, will have on the trading price of our ADSs from time to time. Sales of substantial amounts of our ADSs or ordinary shares in the public market, or the perception that these sales could occur, could adversely affect the trading price of our ADSs.

All of our ordinary shares that will be outstanding upon the completion of this offering, other than those ordinary shares sold in this offering, are "restricted securities" as that term is defined in Rule 144 under the Securities Act and may be sold publicly in the United States only if they are subject to an effective registration statement under the Securities Act or pursuant to an exemption from the registration requirement such as those provided by Rule 144 and Rule 701 promulgated under the Securities Act. In general, beginning 90 days after the date of this prospectus, a person (or persons whose shares are aggregated) who at the time of a sale is not, and has not been during the three months preceding the sale, an affiliate of ours and has beneficially owned our restricted securities for at

least six months will be entitled to sell the restricted securities without registration under the Securities Act, subject only to the availability of current public information about us, and will be entitled to sell restricted securities beneficially owned for at least one year without restriction. Persons who are our affiliates and have beneficially owned our restricted securities for at least six months may sell a number of restricted securities within any three-month period that does not exceed the greater of the following:

Sales by our affiliates under Rule 144 are also subject to certain requirements relating to manner of sale, notice and the availability of current public information about us.

In general, under Rule 701 of the Securities Act as currently in effect, each of our employees, consultants or advisors who purchases our ordinary shares from us in connection with a compensatory stock plan or other written agreement executed prior to the completion of this offering is eligible to resell those ordinary shares in reliance on Rule 144, but without compliance with some of the restrictions, including the holding period, contained in Rule 144. However, the Rule 701 shares would remain subject to lock-up arrangements and would only become eligible for sale when the lock-up period expires.

The following summary of the material Cayman Islands, PRC and U.S. federal income tax consequences of an investment in our ADSs or ordinary shares is based upon laws and relevant interpretations thereof in effect as of the date of this registration statement, all of which are subject to change. This summary does not deal with all possible tax consequences relating to an investment in our ADSs or ordinary shares, such as the tax consequences under U.S. state and local tax laws or under the tax laws of jurisdictions other than the Cayman Islands, China and the United States.

The Cayman Islands 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 Cayman Islands except for stamp duties which may be applicable on instruments executed in, or brought within the jurisdiction of the Cayman Islands. The Cayman Islands is not party to any double tax treaties that are applicable to any payments made to or by our company. There are no exchange control regulations or currency restrictions in the Cayman Islands.

Under the PRC Enterprise Income Tax Law and its implementation rules, an enterprise established outside China with "de facto management body" within China is considered a resident enterprise. The implementation rules define the term "de facto management body" as the body that exercises full and substantial control and overall management over the business, productions, personnel, accounts and properties of an enterprise. In April 2009, the State Administration of Taxation issued a circular, known as Circular 82, which provides certain specific criteria for determining whether the "de facto management body" of a PRC-controlled enterprise that is incorporated offshore is located in China. Although this circular only applies to offshore enterprises controlled by PRC enterprises or PRC enterprise groups, not those controlled by PRC individuals or foreigners, the criteria set forth in the circular may reflect the State Administration of Taxation's general position on how the "de facto management body" text should be applied in determining the tax resident status of all offshore enterprises. According to Circular 82, an offshore incorporated enterprise controlled by a PRC enterprise or a PRC enterprise group will be regarded as a PRC tax resident by virtue of having its "de facto management body" in China only if all of the following conditions are met: (i) the primary location of the day-to-day operational management is in China; (ii) decisions relating to the enterprise's financial and human resource matters are made or are subject to approval by organizations or personnel in China; (iii) the enterprise's primary assets, accounting books and records, company seals, and board and shareholder resolutions, are located or maintained in China; and (iv) at least 50% of voting board members or senior executives habitually reside in China.

We believe that Bilibili Inc. is not a PRC resident enterprise for PRC tax purposes. Bilibili Inc. is not controlled by a PRC enterprise or PRC enterprise group and we do not believe that Bilibili Inc. meets all of the conditions above. Bilibili Inc. is a company incorporated outside China. As a holding company, its key assets are its ownership interests in its subsidiaries, and its key assets are located, and its records (including the resolutions of its board of directors and the resolutions of its shareholders) are maintained, outside China. In addition, we are not aware of any offshore holding companies with a similar corporate structure as ours ever having been deemed a PRC "resident enterprise" by the PRC tax authorities. However, the tax resident status of an enterprise is subject to determination by the PRC tax authorities and uncertainties remain with respect to the interpretation of the term "de facto management body."

If the PRC tax authorities determine that Bilibili Inc. is a PRC resident enterprise for enterprise income tax purposes, we may be required to withhold a 10% withholding tax from dividends we pay to our shareholders that are non-resident enterprises, including the holders of our ADSs. In addition, non-resident enterprise shareholders (including our ADS holders) may be subject to a 10% PRC tax on gains realized on the sale or other disposition of ADSs or ordinary shares, if such income is treated as sourced from within China. It is unclear whether our non-PRC individual shareholders (including our ADS holders) would be subject to any PRC tax on dividends or gains obtained by such non-PRC individual shareholders in the event we are determined to be a PRC resident enterprise. If any PRC tax were to apply to such dividends or gains, it would generally apply at a rate of 20% unless a reduced rate is available under an applicable tax treaty. However, it is also unclear whether non-PRC shareholders of Bilibili Inc. would be able to claim the benefits of any tax treaties between their country of tax residence and China in the event that Bilibili Inc. is treated as a PRC resident enterprise. See "Risk Factors—Risks Related to Doing Business in China—Under the PRC Enterprise Income Tax Law, we may be classified as a PRC resident enterprise, which could result in unfavorable tax consequences to us and our shareholders and have a material adverse effect on our results of operations and the value of your investment."

The following discussion is a summary of U.S. federal income tax considerations relating to the ownership and disposition of our ADSs or ordinary shares by a U.S. Holder (as defined below) that acquires our ADSs in this offering and holds our ADSs as "capital assets" (generally, property held for investment) under the Internal Revenue Code of 1986, as amended, or the Code. This discussion is based upon existing U.S. federal tax law, which is subject to differing interpretations or change, possibly with retroactive effect. No ruling has been sought from the Internal Revenue Service, or the IRS, with respect to any U.S. federal income tax consequences described below, and there can be no assurance that the IRS or a court will not take a contrary position. This discussion does not discuss all aspects of U.S. federal income taxation that may be important to particular investors in light of their individual investment circumstances, including investors subject to special tax rules (including for example, financial institutions, insurance companies, regulated investment companies, real estate investment trusts, broker-dealers, traders in securities that elect mark-to-market treatment, tax-exempt organizations (including private foundations), holders who are not U.S. Holders, holders who own (directly, indirectly or constructively) 10% or more of our voting stock, holders who acquire their ADSs or ordinary shares pursuant to any employee share option or otherwise as compensation, investors that will hold their ADSs or ordinary shares as part of a straddle, hedge, conversion, constructive sale or other integrated transaction for U.S. federal income tax purposes, or investors that have a functional currency other than the U.S. dollar, all of whom may be subject to tax rules that differ significantly from those discussed below). This discussion, moreover, does not address the U.S. federal estate and gift tax or alternative minimum tax consequences of the ownership or disposition of our ADSs or ordinary shares or the Medicare tax on net investment income. Each U.S. Holder is urged to consult its tax advisor regarding the U.S. federal, state, local and non-U.S. income and other tax considerations of an investment in our ADSs or ordinary shares.

For purposes of this discussion, a "U.S. Holder" is a beneficial owner of our ADSs or ordinary shares that is, for U.S. federal income tax purposes, (i) an individual who is a citizen or resident of the United States, (ii) a corporation (or other entity treated as a corporation for U.S. federal income tax purposes) created in, or organized under the law of, the United States or any state thereof or the District of Columbia, (iii) an estate the income of which is includible in gross income for U.S. federal income tax purposes regardless of its source, or (iv) a trust (A) the administration of which is subject to the primary supervision of a U.S. court and which has one or more U.S. persons who have the

authority to control all substantial decisions of the trust or (B) that has otherwise validly elected to be treated as a U.S. person under the Code.

If a partnership (or other entity treated as a partnership for U.S. federal income tax purposes) is a beneficial owner of our ADSs or ordinary shares, the tax treatment of a partner in the partnership will generally depend upon the status of the partner and the activities of the partnership. Partnerships holding our ADSs or ordinary shares and their partners are urged to consult their tax advisors regarding an investment in our ADSs or ordinary shares.

For U.S. federal income tax purposes, a U.S. Holder of ADSs will generally be treated as the beneficial owner of the underlying shares represented by the ADSs. Accordingly, deposits or withdrawals of ordinary shares for ADSs will generally not be subject to U.S. federal income tax.

A non-U.S. corporation, such as our company, will be classified as a PFIC, for U.S. federal income tax purposes for any taxable year, if either (i) 75% or more of its gross income for such year consists of certain types of "passive" income or (ii) 50% or more of the value of its assets (determined on the basis of a quarterly average) during such year is attributable to assets that produce or are held for the production of passive income. For this purpose, cash and assets readily convertible into cash are categorized as a passive asset and the company's goodwill and other unbooked intangibles are taken into account. Passive income generally includes, among other things, dividends, interest, rents, royalties, and gains from the disposition of passive assets. We will be treated as owning a proportionate share of the assets and earning a proportionate share of the income of any other corporation in which we own, directly or indirectly, more than 25% (by value) of the stock.

Although the law in this regard is not entirely clear, we treat our VIEs as being owned by us for U.S. federal income tax purposes, because we control their management decisions and we are entitled to substantially all of the economic benefits associated with these entities, and, as a result, we consolidate their results of operations in our consolidated U.S. GAAP financial statements. If it were determined, however, that we do not own the stock of our VIEs for U.S. federal income tax purposes, we may be treated as a PFIC for the current taxable year and any subsequent taxable year.

Assuming that we are the owner of our VIEs for U.S. federal income tax purposes, and based upon our current and projected income and assets, including the proceeds from this offering, and projections as to the value of our assets, based in part on the projected market value of our ADSs following this offering, we do not expect to be a PFIC for the current taxable year or in the foreseeable future. While we do not expect to be or become a PFIC in the current or future taxable years, the determination of whether we are or will become a PFIC will depend in part upon the value of our goodwill and other unbooked intangibles (which will depend upon the market value of our ADSs from time-to-time, which may be volatile). In estimating the value of our goodwill and other unbooked intangibles, we have taken into account our anticipated market capitalization immediately following the close of this offering. Among other matters, if our market capitalization is less than anticipated or subsequently declines, we may be or become a PFIC for the current or future taxable years. In addition, the composition of our income and our assets will be affected by how, and how quickly, we spend our liquid assets and the cash raised in this offering. Under circumstances where we determine not to deploy significant amounts of cash for capital expenditures and other general corporate purposes, our risk of becoming classified as a PFIC may substantially increase.

Furthermore, because there are uncertainties in the application of the relevant rules, it is possible that the IRS may challenge our classification of certain income or assets as non-passive, or our valuation of our goodwill and other unbooked intangibles, each of which may result in our company becoming classified as a PFIC for the current or subsequent taxable years. Because determination of PFIC status is a fact-intensive inquiry made on an annual basis and will depend upon the composition

of our assets and income, and the continued existence of our goodwill at that time, no assurance can be given that we are not or will not become classified as a PFIC. Our special U.S. counsel expresses no opinion with respect to our PFIC status and also expresses no opinion with respect to our expectations regarding our PFIC status. If we are classified as a PFIC for any year during which a U.S. Holder holds our ADSs or ordinary shares, we generally will continue to be treated as a PFIC for all succeeding years during which such U.S. Holder holds our ADSs or ordinary shares.

The discussion below under "Dividends" and "Sale or Other Disposition of ADSs or Ordinary Shares" is written on the basis that we will not be classified as a PFIC for U.S. federal income tax purposes. The U.S. federal income tax rules that apply if we are treated as a PFIC are generally discussed below under "Passive Foreign Investment Company Rules."

Subject to the discussion below under "Passive Foreign Investment Company Rules," any cash distributions (including the amount of any tax withheld) paid on our ADSs or ordinary shares out of our current or accumulated earnings and profits, as determined under U.S. federal income tax principles, will generally be includible in the gross income of a U.S. Holder as dividend income on the day actually or constructively received by the U.S. Holder. Because we do not intend to determine our earnings and profits on the basis of U.S. federal income tax principles, any distribution we pay will generally be treated as a "dividend" for U.S. federal income tax purposes.

A non-corporate U.S. Holder will generally be subject to tax on dividend income from a "qualified foreign corporation" at a lower applicable capital gains rate rather than the marginal tax rates generally applicable to ordinary income provided that certain holding period requirements are met. A non-U.S. corporation (other than a corporation that is classified as a PFIC for the taxable year in which the dividend is paid or the preceding taxable year) will generally be considered to be a qualified foreign corporation (i) if it is eligible for the benefits of a comprehensive tax treaty with the United States which the Secretary of Treasury of the United States determines is satisfactory for purposes of this provision and which includes an exchange of information program, or (ii) with respect to any dividend it pays on stock (or ADSs in respect of such stock) which is readily tradable on an established securities market in the United States. We intend to list our ADSs on the [New York Stock Exchange/Nasdaq Global Select Market]. Provided the listing is approved, we believe that the ADSs will be readily tradable on an established securities market in the United States, and that we will be a qualified foreign corporation with respect to dividends paid on the ADSs. Since we do not expect that our ordinary shares will be listed on an established securities market, we do not believe that dividends that we pay on our ordinary shares that are not represented by ADSs will meet the conditions required for the reduced tax rate. There can be no assurance that our ADSs will continue to be considered readily tradable on an established securities market in later years.

In the event that we are deemed to be a PRC resident enterprise under the PRC Enterprise Income Tax Law, we may be eligible for the benefits of the U.S.-PRC income tax treaty (which the U.S. Treasury Department has determined is satisfactory for this purpose) and in that case we would be treated as a qualified foreign corporation with respect to dividends paid on our ordinary shares,or ADSs. Each non-corporate U.S. Holder is advised to consult its tax advisors regarding the availability of the reduced tax rate applicable to qualified dividend income for any dividends we pay with respect to our ADSs or ordinary shares. Dividends received on our ADSs or ordinary shares will not be eligible for the dividends received deduction allowed to corporations.

Dividends will generally be treated as income from foreign sources for U.S. foreign tax credit purposes and will generally constitute passive category income. In the event that we are deemed to be a PRC resident enterprise under the PRC Enterprise Income Tax Law, a U.S. Holder may be subject to PRC withholding taxes on dividends paid on our ADSs or ordinary shares. See "Taxation—PRC

Taxation." In that case, depending on the U.S. Holder's individual facts and circumstances, a U.S. Holder may be eligible, subject to a number of complex limitations, to claim a foreign tax credit not in excess of any applicable treaty rate in respect of any foreign withholding taxes imposed on dividends received on our ADSs or ordinary shares. A U.S. Holder who does not elect to claim a foreign tax credit for foreign tax withheld may instead claim a deduction, for U.S. federal income tax purposes, in respect of such withholding, but only for a year in which such holder elects to do so for all creditable foreign income taxes. The rules governing the foreign tax credit are complex and their outcome depends in large part on the U.S. Holder's individual facts and circumstances. Accordingly, U.S. Holders are urged to consult their tax advisors regarding the availability of the foreign tax credit under their particular circumstances.

Subject to the discussion below under "Passive Foreign Investment Company Rules," a U.S. Holder will generally recognize capital gain or loss upon the sale or other disposition of ADSs or ordinary shares in an amount equal to the difference between the amount realized upon the disposition and the holder's adjusted tax basis in such ADSs or ordinary shares. Any capital gain or loss will be long-term if the ADSs or ordinary shares have been held for more than one year and will generally be U.S. source gain or loss for U.S. foreign tax credit purposes. Long-term capital gain of non-corporate U.S. Holders is generally eligible for a reduced rate of taxation. The deductibility of a capital loss may be subject to limitations. In the event that we are treated as a PRC "resident enterprise" under the Enterprise Income Tax Law and gain from the disposition of the ADSs or ordinary shares is subject to tax in the PRC, a U.S. Holder that is eligible for the benefits of the income tax treaty between the United States and the PRC may elect to treat the gain as PRC source income. If you are not eligible for the benefits of the income tax treaty or you fail to make the election to treat any gain as foreign source, then you may not be able to use the foreign tax credit arising from any PRC tax imposed on the disposition of the ADSs or ordinary shares unless such credit can be applied (subject to applicable limitations) against U.S. federal income tax due on other income derived from foreign sources in the same income category (generally, the passive category). U.S. Holders are urged to consult their tax advisors regarding the tax consequences if a foreign tax is imposed on a disposition of our ADSs or ordinary shares, including the availability of the foreign tax credit under their particular circumstances and the election to treat any gain as PRC source.

If we are classified as a PFIC for any taxable year during which a U.S. Holder holds our ADSs or ordinary shares, and unless the U.S. Holder makes a mark-to-market election (as described below), the U.S. Holder will generally be subject to special tax rules that have a penalizing effect, regardless of whether we remain a PFIC, on (i) any excess distribution that we make to the U.S. Holder (which generally means any distribution paid during a taxable year to a U.S. Holder that is greater than 125 percent of the average annual distributions paid in the three preceding taxable years or, if shorter, the U.S. Holder's holding period for the ADSs or ordinary shares), and (ii) any gain realized on the sale or other disposition, including a pledge, of ADSs or ordinary shares. Under the PFIC rules:

If we are a PFIC for any taxable year during which a U.S. Holder holds our ADSs or ordinary shares and any of our subsidiaries is also a PFIC, such U.S. Holder would be treated as owning a proportionate amount (by value) of the shares of the lower-tier PFIC for purposes of the application of these rules. U.S. Holders are urged to consult their tax advisors regarding the application of the PFIC rules to any of our subsidiaries.

As an alternative to the foregoing rules, a U.S. Holder of "marketable stock" in a PFIC may make a mark-to-market election with respect to such stock. The mark-to-market election is available only for stock that is regularly traded on a national securities exchange that is registered with the SEC, or on a foreign exchange or market that the IRS determines is a qualified exchange that has rules sufficient to ensure that the market price represents a legitimate and sound fair market value. Although we have applied to list our ADSs on the [New York Stock Exchange/Nasdaq Global Select Market], we cannot guarantee that our listing will be approved or that this exchange is qualified in the current or future taxable years for purposes of the mark-to-market election. Furthermore, we cannot guarantee that, once listed, our ADSs will continue to be listed and traded on the [New York Stock Exchange/Nasdaq Global Select Market]. If a U.S. Holder makes this election, the holder will generally (i) include as ordinary income for each taxable year that we are a PFIC the excess, if any, of the fair market value of ADSs held at the end of the taxable year over the adjusted tax basis of such ADSs and (ii) deduct as an ordinary loss the excess, if any, of the adjusted tax basis of the ADSs over the fair market value of such ADSs held at the end of the taxable year, but such deduction will only be allowed to the extent of the amount previously included in income as a result of the mark-to-market election. The U.S. Holder's adjusted tax basis in the ADSs would be adjusted to reflect any income or loss resulting from the mark-to-market election. If a U.S. Holder makes a mark-to-market election in respect of a corporation classified as a PFIC and such corporation ceases to be classified as a PFIC, the holder will not be required to take into account the gain or loss described above during any period that such corporation is not classified as a PFIC. If a U.S. Holder makes a mark-to-market election, any gain such U.S. Holder recognizes upon the sale or other disposition of our ADSs in a year when we are a PFIC will be treated as ordinary income and any loss will be treated as ordinary loss, but such loss will only be treated as ordinary loss to the extent of the net amount previously included in income as a result of the mark-to-market election. If a U.S. Holder makes a mark-to-market election it will be effective for the taxable year for which the election is made and all subsequent taxable years unless the ADSs are no longer treated as marketable stock or the IRS consents to the revocation of the election. It should also be noted that it is intended that only the ADSs and not the ordinary shares will be listed on the [New York Stock Exchange/Nasdaq Global Select Market]. Consequently, if a U.S. Holder holds ordinary shares that are not represented by ADSs, such holder generally will not be eligible to make a mark-to-market election if we are or were to become a PFIC.

Because a mark-to-market election cannot be made for any lower-tier PFICs that we may own, a U.S. Holder may continue to be subject to the PFIC rules with respect to such U.S. Holder's indirect interest in any investments held by us that are treated as an equity interest in a PFIC for U.S. federal income tax purposes.

We do not intend to provide information necessary for U.S. Holders to make qualified electing fund elections which, if available, would result in tax treatment different from the general tax treatment for PFICs described above.

As discussed above under "Dividends," dividends that we pay on our ADSs or ordinary shares will not be eligible for the reduced tax rate that applies to qualified dividend income if we are a PFIC for the taxable year in which the dividend is paid or the preceding taxable year. In addition, if a U.S. Holder owns our ADSs or ordinary shares during any taxable year that we are a PFIC, the holder must generally file an annual IRS Form 8621. Each U.S. Holder is urged to consult its tax advisor concerning the U.S. federal income tax consequences of purchasing, holding and disposing ADSs or ordinary shares if we are or become treated as a PFIC, including the possibility of making a mark-to-market election.

Certain U.S. Holders are required to report information to the IRS relating to an interest in "specified foreign financial assets," including shares issued by a non-U.S. corporation, for any year in which the aggregate value of all specified foreign financial assets exceeds US$50,000 (or a higher dollar amount prescribed by the IRS), subject to certain exceptions (including an exception for shares held in custodial accounts maintained with a U.S. financial institution). These rules also impose penalties if a U.S. Holder is required to submit such information to the IRS and fails to do so.

In addition, U.S. Holders may be subject to information reporting to the IRS with respect to dividends on and proceeds from the sale or other disposition of our ADSs or ordinary shares. Each U.S. Holder is advised to consult with its tax advisor regarding the application of the U.S. information reporting rules to their particular circumstances.

We and the underwriters named below have entered into an underwriting agreement with respect to the ADSs being offered. Under the terms and subject to the conditions contained in the underwriting agreement, each underwriter has severally agreed to purchase the number of ADSs indicated in the following table. Merrill Lynch, Pierce, Fenner & Smith Incorporated, J.P. Morgan Securities LLC and Morgan Stanley & Co. International plc are acting as joint bookrunners of this offering and as the representatives of the underwriters.

The underwriters are offering the ADSs subject to their acceptance of the ADSs from us and subject to prior sale. The underwriting agreement provides that the obligations of the several underwriters to pay for and accept delivery of the ADSs offered by this prospectus are subject to the approval of certain legal matters by their counsel and to certain other conditions. The underwriters are obligated, severally and not jointly, to take and pay for all of the ADSs offered by this prospectus if any such ADSs are taken, other than the ADSs covered by the underwriters' option to purchase additional ADSs described below. The underwriting agreement also provides that if an underwriter defaults, the purchase commitments of non-defaulting underwriters may be increased or the offering may be terminated.

The underwriters initially propose to offer part of the ADSs directly to the public at the public offering price listed on the cover page of this prospectus and part of the ADSs to certain dealers at a price that represents a concession not in excess of US$ per ADS from the initial public offering price. After the initial offering of the ADSs, the offering price and other selling terms may from time to time be varied by the underwriters.

Certain of the underwriters are expected to make offers and sales both inside and outside the United States through their respective selling agents. Any offers or sales in the United States will be conducted by broker-dealers registered with the SEC.

We have granted to the underwriters an option, exercisable for 30 days from the date of this prospectus, to purchase up to an aggregate of additional ADSs from us at the public offering price listed on the cover page of this prospectus, less underwriters discounts and commissions. To the extent the option is exercised, each underwriter will become severally obligated, subject to certain conditions, to purchase additional ADSs approximately proportionate to each underwriter's initial amount reflected in the table above.

Total underwriting discounts and commissions to be paid to the underwriters represent % of the total amount of the offering. The following table shows the per ADS and total underwriting

discounts and commissions to be paid to the underwriters by us. Such amounts are shown assuming both no exercise and full exercise of the underwriters' option to purchase additional ADSs.

The underwriters have agreed to reimburse us for a certain portion of our expenses in connection with our initial public offering.

The estimated offering expenses payable by us, exclusive of the underwriting discounts and commissions, are approximately US$ million, which includes legal, accounting, and printing costs and various other fees associated with the registration of our ordinary shares and ADSs.

[We, our directors and executive officers, our existing shareholders [and certain option holders] have agreed with the underwriters to certain lock-up restrictions in respect of our ordinary shares, ADSs or securities that are substantially similar to our ordinary shares or ADSs during the period ending 180 days after the date of this prospectus, subject to certain exceptions. Immediately after the completion of this offering, a total of ordinary shares (representing approximately % of our ordinary shares then issued and outstanding) will be subject to the lock-up agreements or other restrictions on transfer. See "Shares Eligible for Future Sales." ]

The representatives, in their sole discretion, may release our ordinary shares and ADSs and other securities subject to the lock-up agreements described above in whole or in part at any time.

Our ADSs have been approved for listing on the [New York Stock Exchange/Nasdaq Global Select Market] under the symbol "BILI."

In connection with the offering, the underwriters may purchase and sell ADSs in the open market. These transactions may include short sales in accordance with Regulation M under the Exchange Act, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater number of ADSs than they are required to purchase in the offering. "Covered" short sales are sales made in an amount not greater than the underwriters' option to purchase additional ADSs in the offering. The underwriters may close out any covered short position by either exercising their option to purchase additional ADSs or purchasing ADSs in the open market. In determining the source of ADSs to close out the covered short position, the underwriters will consider, among other things, the price of ADSs available for purchase in the open market as compared to the price at which they may purchase additional ADSs pursuant to the option granted to them. "Naked" short sales are any sales in excess of such option. The underwriters must close out any naked short position by purchasing ADSs in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the ADSs in the open market after pricing that could adversely affect investors who purchase in the offering. Stabilizing transactions consist of various bids for, or purchases of, ADSs made by the underwriters in the open market prior to the completion of the offering.

The underwriters may also impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the representatives

have repurchased ADSs sold by, or for the account of, such underwriter in stabilizing or short covering transactions.

Purchases to cover a short position and stabilizing transactions, as well as other purchases by the underwriters for their own accounts, may have the effect of preventing or retarding a decline in the market price of the ADSs, and together with the imposition of the penalty bid, may stabilize, maintain or otherwise affect the market price of the ADSs. As a result, the price of the ADSs may be higher than the price that otherwise might exist in the open market. If these activities are commenced, they are required to be conducted in accordance with applicable laws and regulations, and they may be discontinued at any time. These transactions may be effected on the [New York Stock Exchange/NASDAQ Global Select Market], the over-the-counter market or otherwise.

A prospectus in electronic format will be made available on the websites maintained by one or more of the underwriters or one or more securities dealers. One or more of the underwriters may distribute prospectuses electronically. The underwriters may agree to allocate a number of ADSs for sale to their online brokerage account holders. ADSs to be sold pursuant to an Internet distribution will be allocated on the same basis as other allocations. In addition, ADSs may be sold by the underwriters to securities dealers who resell ADSs to online brokerage account holders.

At our request, the underwriters have reserved up to % of the ADSs being offered by this prospectus (assuming exercise in full by the underwriters of their option to purchase additional ADSs) for sale at the initial public offering price to certain of our directors, executive officers, employees, business associates and members of their families. The directed ADS program will be administered by . We do not know if these individuals will choose to purchase all or any portion of these reserved ADSs, but any purchases they do make will reduce the number of ADSs that are available to the general public. Any reserved ADSs that are not so purchased will be offered by the underwriters to the general public on the same terms as the other ADSs offered by this prospectus.]

The underwriters do not intend sales to discretionary accounts to exceed 5% of the total number of ADSs offered by them.

We have agreed to indemnify the several underwriters against certain liabilities, including liabilities under the Securities Act.

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include the sales and trading of securities, commercial and investment banking, advisory, investment management, investment research, principal investment, hedging, market making, financing, brokerage and other financial and non-financial activities and services. Certain of the underwriters and their respective affiliates may in the future perform a variety of such activities and services for us and for persons or entities with relationships with us for which they received or will receive customary fees, commissions and expenses.

In the ordinary course of their various business activities, the underwriters and their respective affiliates, directors, officers and employees may at any time purchase, sell or hold a broad array of

investments, and actively trade securities, derivatives, loans, commodities, currencies, credit default swaps and other financial instruments for their own account and for the accounts of their customers. Such investment and trading activities may involve or relate to the assets, securities and/or instruments of us (directly, as collateral securing other obligations or otherwise) and/or persons and entities with relationships with us. The underwriters and their respective affiliates may also communicate independent investment recommendations, market color or trading ideas and/or publish or express independent research views in respect of such assets, securities or instruments. In addition, the underwriters and their respective affiliates may at any time hold, or recommend to clients that they should acquire, long and short positions in such assets, securities and instruments.

Prior to this offering, there has been no public market for our ordinary shares or ADSs. The initial public offering price was determined by negotiations between us and the representatives of the underwriters. Among the factors considered in determining the initial public offering price of the ADSs, in addition to prevailing market conditions, were our historical performance, estimates of our business potential and earnings prospects, an assessment of our management and the consideration of the above factors in relation to market valuation of companies in related businesses.

No action has been taken in any jurisdiction (except in the United States) that would permit a public offering of the ADSs, or the possession, circulation or distribution of this prospectus or any other material relating to us or the ADSs in any jurisdiction where action for that purpose is required. Accordingly, the ADSs may not be offered or sold, directly or indirectly, and neither this prospectus nor any other material or advertisements in connection with the ADSs may be distributed or published, in or from any country or jurisdiction except in compliance with any applicable laws, rules and regulations of any such country or jurisdiction.

The ADSs may not be directly or indirectly offered for subscription or purchased or sold, and no invitations to subscribe for or buy the ADSs may be issued, and no draft or definitive offering memorandum, advertisement or other offering material relating to any ADSs may be distributed in Australia, except where disclosure to investors is not required under Chapter 6D of the Corporations Act or is otherwise in compliance with all applicable Australian laws and regulations. By submitting an application for the ADSs, you represent and warrant to us that you are an Exempt Investor.

As any offer of ADSs under this prospectus will be made without disclosure in Australia under Chapter 6D.2 of the Corporations Act, the offer of those securities for resale in Australia within 12 months may, under section 707 of the Corporations Act, require disclosure to investors under Chapter 6D.2 if none of the exemptions in section 708 applies to that resale. By applying for the ADSs you undertake to us that you will not, for a period of 12 months from the date of issue of the ADSs, offer, transfer, assign or otherwise alienate those securities to investors in Australia except in circumstances where disclosure to investors is not required under Chapter 6D.2 of the Corporations Act or where a compliant disclosure document is prepared and lodged with ASIC.

Bermuda. The ADSs may be offered or sold in Bermuda only in compliance with the provisions of the Investment Business Act of 2003 of Bermuda which regulates the sale of securities in Bermuda. Additionally, non-Bermudian persons (including companies) may not carry on or engage in any trade or business in Bermuda unless such persons are permitted to do so under applicable Bermuda legislation

British Virgin Islands. The ADSs are not being, and may not be offered to the public or to any person in the British Virgin Islands for purchase or subscription by us or on our behalf. The ADSs may be offered to companies incorporated under the BVI Business Companies Act, 2004 (British Virgin Islands) (each a BVI Company), but only where the offer will be made to, and received by, the relevant BVI Company entirely outside of the British Virgin Islands.

This prospectus has not been, and will not be, registered with the Financial Services Commission of the British Virgin Islands. No registered prospectus has been or will be prepared in respect of the ADSs for the purposes of the Securities and Investment Business Act, 2010, or SIBA or the Public Issuers Code of the British Virgin Islands.

The ADSs may be offered to persons located in the British Virgin Islands who are "qualified investors" for the purposes of SIBA. Qualified investors include (i) certain entities which are regulated by the Financial Services Commission in the British Virgin Islands, including banks, insurance companies, licensees under SIBA and public, professional and private mutual funds; (ii) a company, any securities of which are listed on a recognised exchange; and (iii) persons defined as "professional investors" under SIBA, which is any person (a) whose ordinary business involves, whether for that person's own account or the account of others, the acquisition or disposal of property of the same kind as the property, or a substantial part of our property; or (b) who has signed a declaration that he, whether individually or jointly with his spouse, has a net worth in excess of US$1,000,000 and that he consents to being treated as a professional investor.

The distribution of the ADSs in Canada is being made only in the provinces of Ontario, Quebec, Alberta and British Columbia on a private placement basis exempt from the requirement that we prepare and file a prospectus with the securities regulatory authorities in each province where trades of the ADSs are made. Any resale of the ADSs in Canada must be made under applicable securities laws which may vary depending on the relevant jurisdiction, and which may require resales to be made under available statutory exemptions or under a discretionary exemption granted by the applicable Canadian securities regulatory authority. Purchasers are advised to seek legal advice prior to any resale of the securities.

By purchasing ADSs in Canada and accepting delivery of a purchase confirmation, a purchaser is representing to us and the dealer from whom the purchase confirmation is received that:

Canadian purchasers are hereby notified that the underwriters are relying on the exemption set out in section 3A.3 or 3A.4, if applicable, of National Instrument 33-105—Underwriting Conflicts from having to provide certain conflict of interest disclosure in this prospectus.

Securities legislation in certain provinces or territories of Canada may provide a purchaser with remedies for rescission or damages if the offering memorandum (including any amendment thereto) such as this prospectus contains a misrepresentation, provided that the remedies for rescission or damages are exercised by the purchaser within the time limit prescribed by the securities legislation of the purchaser's province or territory. The purchaser of these securities in Canada should refer to any applicable provisions of the securities legislation of the purchaser's province or territory for particulars of these rights or consult with a legal advisor.

All of our directors and officers as well as the experts named herein may be located outside of Canada and, as a result, it may not be possible for Canadian purchasers to effect service of process within Canada upon us or those persons. All or a substantial portion of our assets and the assets of those persons may be located outside of Canada and, as a result, it may not be possible to satisfy a judgment against us or those persons in Canada or to enforce a judgment obtained in Canadian courts against us or those persons outside of Canada.

Canadian purchasers of ADSs should consult their own legal and tax advisors with respect to the tax consequences of an investment in the ADSs in their particular circumstances and about the eligibility of the ADSs for investment by the purchaser under relevant Canadian legislation.

European Economic Area. In relation to each Member State of the European Economic Area which has implemented the Prospectus Directive (each, a Relevant Member State), with effect from and including the date on which the Prospectus Directive was implemented in that Relevant Member State (the Relevant Implementation Date), an offer of the ADSs to the public may not be made in that Relevant Member State prior to the publication of a prospectus in relation to the ADSs which has been approved by the competent authority in that Relevant Member State or, where appropriate, approved in another Relevant Member State and notified to the competent authority in that Relevant Member State, all in accordance with the Prospectus Directive, except that, with effect from and including the Relevant Implementation Date, an offer of ADSs may be made to the public in that Relevant Member State at any time:

Immediately upon the effectiveness of the registration statement on Form F-1 of which this prospectus forms a part, we will become subject to periodic reporting and other informational requirements of the Exchange Act as applicable to foreign private issuers. Accordingly, we will be required to file reports, including annual reports on Form 20-F, and other information with the SEC. All information filed with the SEC can be obtained over the internet at the SEC's website at www.sec.gov or inspected and copied at the public reference facilities maintained by the SEC at 100 F Street, N.E., Washington, D.C. 20549.

In addition, we will not be required under the Exchange Act to file periodic reports and financial statements with the SEC as frequently or as promptly as U.S. companies whose securities are registered under the Exchange Act. However, we intend to furnish the depositary with our annual reports, which will include a review of operations and annual audited consolidated financial statements prepared in conformity with U.S. GAAP, and all notices of shareholders' meetings and other reports and communications that are made generally available to our shareholders. The depositary will make such notices, reports and communications available to holders of ADSs and, if we so request, will mail to all record holders of ADSs the information contained in any notice of a shareholders' meeting received by the depositary from us.

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States) and in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

and (ii) the contractual agreements entered into by and among Hode Technology, Shanghai Kuanyu and the nominee shareholders of Shanghai Kuanyu

Exclusive Technology Consulting and Services Agreements. Under the exclusive technology consulting and services agreement between Hode Technology and Shanghai Kuanyu, dated November 3, 2014, Hode Technology has the exclusive right to provide to Shanghai Kuanyu consulting and services related to, among other things, research and development, system operation, advertising, internal training and technical support. Hode Technology has the exclusive ownership of intellectual property rights created as a result of the performance of this agreement. Shanghai Kuanyu shall pay Hode Technology an annual service fee, which subject to the adjustment by Hode Technology at its sole discretion. This agreement will remain effective for a 10-year term and then be automatically renewed, unless Hode Technology gives Shanghai Kuanyu a termination notice 90 days before the term ends.

Exclusive Option Agreements. Pursuant to the exclusive purchase option agreement, dated November 3, 2014, among Hode Technology, Shanghai Kuanyu and their shareholders, each of the shareholders of Shanghai Kuanyu irrevocably granted Hode Technology an exclusive option to purchase, or have its designated person to purchase, at its discretion, to the extent permitted under PRC law, all or part of their equity interests in Shanghai Kuanyu, and the purchase price shall be the lowest price permitted by applicable PRC law. In addition, Shanghai Kuanyu irrevocably granted Hode Technology an exclusive option to purchase, or have its designated person to purchase, at its discretion, to the

extent permitted under PRC law, all or part of Shanghai Kuanyu's assets at the book value of such assets, or at the lowest price permitted by applicable PRC law, whichever is higher. The shareholders of Shanghai Kuanyu undertakes that, without the prior written consent of Hode Technology or the Company, they shall not increase or decrease the registered capital, dispose of its assets, incur any debts or guarantee liabilities, enter into any material purchase agreements, conduct any merger, acquisition or investments, amend its articles of association or provide any loans to third parties. The exclusive option agreements will remain effective until all equity interests in Shanghai Kuanyu held by their shareholders and all assets of Shanghai Kuanyu are transferred or assigned to Hode Technology or its designated representatives.

Powers of Attorney. Pursuant to the Powers of Attorney dated November 3, 2014, each of the shareholders of Shanghai Kuanyu, executed a power of attorney to irrevocably appoint Hode Technology or its designated person as his attorney-in-fact to exercise all of his rights as a shareholder of Shanghai Kuanyu, including, but not limited to, the right to convene and attend shareholders' meeting, vote on any resolution that requires a shareholder vote, such as the appointment or removal of directors and executive officers, and other voting rights pursuant to the then-effective articles of association of Shanghai Kuanyu. The power of attorney will remain in force for so long as the shareholders remain shareholders of Shanghai Kuanyu.

Equity Pledge Agreements. Pursuant to the Equity Pledge Agreement dated November 3, 2014, among Hode Technology, Shanghai Kuanyu and their shareholders, the shareholders pledged all of their equity interests in Shanghai Kuanyu to guarantee their and Shanghai Kuanyu's performance of their obligations under the contractual arrangements. In the event of a breach by Shanghai Kuanyu or Shanghai Kuanyu's shareholders of contractual obligations under these agreements, Hode Technology, as pledgee, will be entitled the right to dispose of the pledged equity interests in Shanghai Kuanyu. The shareholders of Shanghai Kuanyu also undertakes that, during the term of the equity pledge agreements, they shall not dispose of the pledged equity interests or create or allow any encumbrance on the pledged equity interests. During the term of the equity pledge agreement, Hode Technology has the right to receive all of the dividends and profits distributed on the pledged equity interests. The pledge will remain binding until Shanghai Kuanyu and their shareholders discharge all their obligations under the contractual arrangements.

On June 2, 2015, the contractual agreements among Hode Technology, Shanghai Kuanyu, and nominee shareholders of Shanghai Kuanyu were updated to remove one of the nominee shareholders of Shanghai Kuanyu. On October 10, 2017, the contractual agreements among Hode Technology, Shanghai Hode, and the nominee shareholders of Shanghai Hode were updated to remove one of the nominee shareholders of Shanghai Hode. These changes have no impact on the Group's effective control over Shanghai Kuanyu and Shanghai Hode, and therefore had no impact on the consolidated financial statements.

A significant part of the Group's business is conducted through the VIEs of the Group, of which the Company is the ultimate primary beneficiary. In the opinion of management, the contractual arrangements with the VIEs and the nominee shareholders are in compliance with PRC laws and

regulations and are legally binding and enforceable. The nominee shareholders are also shareholders of the Group and have indicated they will not act contrary to the contractual arrangements. However, there are substantial uncertainties regarding the interpretation and application of PRC laws and regulations including those that govern the contractual arrangements, which could limit the Group's ability to enforce these contractual arrangements and if the nominee shareholders of the VIE were to reduce their interests in the Group, their interest may diverge from that of the Group and that may potentially increase the risk that they would seek to act contrary to the contractual arrangements.

In January 2015, the Ministry of Commerce ("MOFCOM"), released for public comment a proposed PRC law, the Draft Foreign Investment Enterprises ("FIE") Law, that appears to include VIEs within the scope of entities that could be considered to be FIEs, that would be subject to restrictions under existing PRC law on foreign investment in certain categories of industry. Specifically, the Draft FIE Law introduces the concept of "actual control" for determining whether an entity is considered to be an FIE. In addition to control through direct or indirect ownership or equity, the Draft FIE Law includes control through contractual arrangements within the definition of "actual control". If the Draft FIE Law is passed by the People's Congress of the PRC and goes into effect in its current form, these provisions regarding control through contractual arrangements could be construed to include the Group's contractual arrangements with its VIEs, and as a result, the Group's VIEs could become explicitly subject to the current restrictions on foreign investment in certain categories of industry. The Draft FIE Law includes provisions that would exempt from the definition of FIEs where the ultimate controlling shareholders are either entities organized under PRC law or individuals who are PRC citizens. The Draft FIE Law is silent as to what type of enforcement action might be taken against existing VIE, that operates in restricted or prohibited industries and is not controlled by entities organized under PRC law or individuals who are PRC citizens. If the restrictions and prohibitions on FIEs included in the Draft FIE Law are enacted and enforced in their current form, the Group's ability to use the contractual arrangements with its VIEs and the Group's ability to conduct business through the VIEs could be severely limited.

The Company's ability to control the VIEs also depends on the Power of Attorney the founders has to vote on all matters requiring shareholder approval in the VIEs. As noted above, the Company believes these Power of Attorney are legally enforceable but may not be as effective as direct equity ownership.

In addition, if the Group's corporate structure or the contractual arrangements with the VIEs were found to be in violation of any existing or future PRC laws and regulations, the PRC regulatory authorities could, within their respective jurisdictions:

The imposition of any of these restrictions or actions could result in a material adverse effect on the Group's ability to conduct its business. In such case, the Group may not be able to operate or control the VIEs, which may result in deconsolidation of the VIEs in the Group's consolidated financial statements. In the opinion of management, the likelihood for the Group to lose such ability is remote based on current facts and circumstances. The Group believes that the contractual arrangements among each of the VIEs, their respective shareholders and relevant wholly foreign owned enterprise are in compliance with PRC law and are legally enforceable. The Group's operations depend on the VIEs to honor their contractual arrangements with the Group. These contractual arrangements are governed by PRC law and disputes arising out of these agreements are expected to be decided by arbitration in the PRC. Management believes that each of the contractual arrangements constitutes valid and legally binding obligations of each party to such contractual arrangements under PRC laws. However, the interpretation and implementation of the laws and regulations in the PRC and their application on the legality, binding effect and enforceability of contracts are subject to the discretion of competent PRC authorities, and therefore there is no assurance that relevant PRC authorities will take the same position as the Group herein in respect of the legality, binding effect and enforceability of each of the contractual arrangements. Meanwhile, since the PRC legal system continues to evolve, the interpretations of many laws, regulations and rules are not always uniform and enforcement of these laws, regulations and rules involve uncertainties, which may limit legal protections available to the Group to enforce the contractual arrangements should the VIEs or the nominee shareholders of the VIEs fail to perform their obligations under those arrangements.

The following combined financial information of the Group's VIEs as of December 31, 2015 and 2016 and for the years ended December 31, 2015 and 2016 was included in the accompanying consolidated financial statements of the Group as follows:

	December 31, 2015		December 31, 2016

Total liabilities		218,972		581,386

In accordance with various contractual agreements, the Company has the power to direct the activities of the VIEs and can have assets transferred out of the VIEs. Therefore, the Company considers that there are no assets in the respective VIEs that can be used only to settle obligations of the respective VIEs, except for the registered capital of the VIEs amounting to approximately RMB2.6 million, as of December 31, 2015 and 2016, as well as certain non-distributable statutory reserves amounting to approximately RMB0.6 million and RMB1.6 million, respectively, as of December 31, 2015 and 2016. As the respective VIEs are incorporated as limited liability companies under the PRC Company Law, creditors do not have recourse to the general credit of the Company for the liabilities of the respective VIEs. There is currently no contractual arrangement that would require the Company to provide additional financial support to the VIEs. As the Group is conducting certain businesses in the PRC through the VIEs, the Group may provide additional financial support on a discretionary basis in the future, which could expose the Group to a loss.

There is no VIE in the group where the Company or any subsidiary has a variable interest but is not the primary beneficiary.

The Group incurred net losses of RMB373.5 million and RMB911.5 million in the years ended December 31, 2015 and 2016, respectively. Net cash used in operating activities was RMB191.9 million and RMB199.0 million for the years ended December 31, 2015 and 2016, respectively. Accumulated deficit was RMB655.9 million and RMB1,778.0 million as of December 31, 2015 and 2016, respectively. The Group assesses its liquidity by its ability to generate cash from operating activities and attract investors' investments.

Historically, the Group has relied principally on both operational sources of cash and non-operational sources of financing from investors to fund its operations and business development. The Group's ability to continue as a going concern is dependent on management's ability to successfully execute its business plan, which includes increasing revenues while controlling operating expenses, as well as, generating operational cash flows and continuing to gain support from outside sources of financing. The Group has been continuously receiving financing support from outside investors through the issuance of preferred shares. Refer to Note 17 for details of the Group's preferred shares financing activities. In addition, if the Company successfully completes a qualified initial public offering ("IPO") before November 2, 2022, thereby triggering the automatic conversion of all series of preferred shares into ordinary shares, it will eliminate the possibility of any future cash outflow that may result from the holders of preferred shares exercising their share redemption rights. Moreover, the Group can adjust the pace of its operation expansion and control the operating expenses of the Group. Based on the above considerations, the Group believes the cash and cash equivalents and the operating cash flows are sufficient to meet the cash requirements to fund planned operations and other commitments for at least the next twelve months. The Group's consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and liquidation of liabilities in the normal course of business.

The consolidated financial statements of the Group have been prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP"). Significant accounting policies followed by the Group in the preparation of the accompanying consolidated financial statements are summarized below.

The consolidated financial statements include the financial statements of the Company, its subsidiaries and VIEs for which the Company is the primary beneficiary.

Subsidiaries are those entities in which the Company, directly or indirectly, controls more than one half of the voting power, has the power to appoint or remove the majority of the members of the board of directors, or to cast a majority of votes at the meeting of the board of directors, or has the power to govern the financial and operating policies of the investee under a statute or agreement among the shareholders or equity holders.

A consolidated VIE is an entity in which the Company, or its subsidiary, through contractual arrangements, has the power to direct the activities that most significantly impact the entity's economic performance, bears the risks of and enjoys the rewards normally associated with ownership of the entity, and therefore the Company or its subsidiary is the primary beneficiary of the entity.

All transactions and balances among the Company, its subsidiaries and VIEs have been eliminated upon consolidation.

The preparation of the Group's consolidated financial statements in conformity with the U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent liabilities at the balance sheet date and reported revenues and expenses during the reported periods in the consolidated financial statements and accompanying notes. Significant accounting estimates include, but are not limited to, determination of the average user life for paying users, fair value of identifiable assets and liabilities acquired through business combinations, assessment for the impairment of long-lived assets, valuation allowance of deferred tax assets, determination of the fair value of ordinary shares and preferred shares, and valuation and recognition of share-based compensation expenses.

The Group uses Renminbi ("RMB") as its reporting currency. The functional currency of the Company and its overseas subsidiaries which incorporated in the Cayman Islands and Hong Kong is United States dollars ("US$"). The Company's subsidiaries incorporated in Japan is Japanese yen. The functional currency of the Group's PRC entities is RMB.

In the consolidated financial statements, the financial information of the Company and other entities located outside of the PRC have been translated into RMB. Assets and liabilities are translated at the exchange rates on the balance sheet date, equity amounts are translated at historical exchange

rates, and revenues, expenses, gains and losses are translated using the average rate for the year. Translation adjustments are reported as foreign currency translation adjustments, and are shown as a component of other comprehensive loss in the consolidated statements of operations and comprehensive loss.

Foreign currency transactions denominated in currencies other than the functional currency are translated into the functional currency using the exchange rates prevailing at the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies are translated into the functional currency using the applicable exchange rates at the balance sheet dates. Net gains and losses resulting from foreign exchange transactions are included in exchange losses in the consolidated statements of operations and comprehensive loss.

Translations of balances in the consolidated balance sheets, consolidated statements of operations and comprehensive loss and consolidated statements of cash flows from RMB into US$ as of and for the year ended December 31, 2016 are solely for the convenience of the reader and were calculated at the rate of US$1.00 = RMB6.6533, representing the noon buying rate in The City of New York for cable transfers of RMB as certified for customs purposes by the Federal Reserve Bank of New York on September 29, 2017. No representation is made that the RMB amounts represent or could have been, or could be, converted, realized or settled into US$ at that rate on September 29, 2017, or at any other rate.

Accounting guidance defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, the Group considers the principal or most advantageous market in which it would transact and it considers assumptions that market participants would use when pricing the asset or liability.

Accounting guidance establishes a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument's categorization within the fair value hierarchy is based upon 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 fair value:

The Group's financial instruments include cash and cash equivalents, restricted cash, accounts receivable, and other receivables, short-term investments, accounts payable, short-term loan, and other payables, of which the carrying values approximate their fair value. Please see Note 24 for additional information.

Cash and cash equivalents mainly represent cash on hand, demand deposits placed with large reputable banks in the United States of America or China, and highly liquid investments that are readily convertible to known amounts of cash and with original maturities from the date of purchase with terms of three months or less. As of December 31, 2015 and 2016, there were cash at bank and demand deposits with terms of less than three months denominated in US dollars amounting to approximately US$85.8 million and US$29.3 million, respectively (equivalent to approximately RMB557.2 million and RMB203.2 million, respectively). As of December 31, 2015 and 2016, the Group had cash held in accounts managed by Alipay and Paypal in connection with the collection of service fees online for a total amount of RMB41.5 million and RMB133.7 million, respectively, which have been classified as cash and cash equivalents on the consolidated balance sheets.

As of December 31, 2015 and 2016, the Group had approximately RMB134.9 million and RMB203.4 million cash and cash equivalents held by its PRC subsidiaries and VIEs, representing 19.6% and 52.5% of total cash and cash equivalents of the Group, respectively.

As of December 31, 2015 and 2016, the Group had a restricted cash balance approximately RMB10.1 million and RMB nil, respectively, which is the pledged deposit for a short-term bank loans.

Inventories, mainly represent products for the Group's e-commerce business, are stated at the lower of cost or net realizable value in the consolidated balance sheets. Cost of inventory is determined using the weighted average cost method. Adjustments are recorded to write down the cost of inventories to the estimated net realizable value due to slow-moving merchandise and damaged goods, which is dependent upon factors such as historical and forecasted consumer demand, and promotional environment. The Group takes ownership, risks and rewards of the products purchased. Write downs are recorded in cost of revenues in the consolidated statements of operations and comprehensive loss. Certain costs attributable to buying and receiving products, such as purchase freights, are included in cost of inventories.

Property and equipment are stated at cost less accumulated depreciation and impairment, if any. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, generally from three years. Leasehold improvements are amortized over the shorter of the estimated useful lives of the assets or the remaining lease term. Expenditures for maintenance and repairs are expensed as incurred. The gain or loss on the disposal of property and equipment is the difference between the net sales proceeds and the carrying amount of the relevant assets and is recognized in the consolidated statements of operations and comprehensive loss.

Intangible assets acquired through business acquisitions are recognized as assets separate from goodwill if they satisfy either the "contractual-legal" or "separability" criterion. Purchased intangible assets are initially recognized and measured at fair value. Major identifiable intangible assets that have determinable lives continue to be amortized over their estimated useful lives using the straight-line method as follows:

The licensed copyrights of video content are recorded in "Intangible assets, net", at the lower of amortized cost or net realizable value. In accordance with ASC topic 920 ("ASC 920"), Entertainment-Broadcasters, costs incurred in purchased copyrights of video content are capitalized and amortized over the shorter of the license period or projected useful life of the video content. Any licensed copyrights that do not meet the criteria to be recorded are included in the commitments disclosure. The Group amortizes the licensed copyrights in "Cost of revenues" on a straight line basis. If expectations of the usefulness of a video content are revised downward, the unamortized cost is written down to the estimated net realizable value. A write-down from unamortized cost to a lower estimated net realizable value establishes a new cost basis.

Goodwill represents the excess of the purchase consideration over the fair value of the identifiable tangible and intangible assets acquired and liabilities assumed from the acquired entity as a result of the Company's acquisitions of interests in its subsidiaries and consolidated VIEs. Goodwill is not depreciated or amortized but is tested for impairment at the reporting unit level on an annual basis, and between annual tests when an event or circumstances change occurs that indicate the asset might be impaired. Under ASC 350-20-35, the Group has the option to choose whether it will apply the qualitative assessment first and then the quantitative assessment, if necessary, or to apply the quantitative assessment directly. The Group chooses to directly apply the quantitative impairment test, which consists of a two-step quantitative impairment test. The first step is comparing the carrying amount of the reporting unit to the fair value of the reporting unit. If the fair value of the reporting

unit exceeds the carrying value of the reporting unit, goodwill is not impaired and the Group is not required to perform further testing. If the carrying value of the reporting unit exceeds the fair value of the reporting unit, then the Group must perform the second step of the two step quantitative goodwill impairment test to measure the amount of impairment loss by comparing the implied fair value of the reporting unit goodwill with the carrying amount of that goodwill. 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. The judgment in estimating the fair value of reporting units includes estimating future cash flows, determining appropriate discount rates and making other assumptions. Changes in these estimates and assumptions could materially affect the determination of fair value for each reporting unit. The Group as a whole is determined to be one reporting unit for goodwill impairment testing. The Company directly applied the quantitative assessment and performed the goodwill impairment test by quantitatively comparing the fair values of the reporting unit to its carrying amounts, and no impairment charge was recognized for any of the periods presented.

l) Impairment of long-lived assets other than goodwill and licensed copyrights

Long-lived assets are evaluated for impairment whenever events or changes in circumstances (such as a significant adverse change to market conditions that will impact the future use of the assets) indicate that the carrying value of an asset may not be fully recoverable or that the useful life is shorter than the Group had originally estimated. When these events occur, the Group evaluates the impairment for the long-lived assets by comparing the carrying value of the assets to an estimate of future undiscounted cash flows expected to be generated from the use of the assets and their eventual disposition. If the sum of the expected future undiscounted cash flows is less than the carrying value of the assets, the Group recognizes an impairment loss based on the excess of the carrying value of the assets over the fair value of the assets. No impairment charge was recognized for any of the periods presented.

The Group recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable and collectability is reasonably assured. Net revenues presented in the consolidated statements of operations and comprehensive loss are net of sales discount, sales tax and related surcharges.

For the year ended December 31, 2015 and 2016, the Group primarily generates revenues from the sale of in-game virtual items, including characters, warships, characters or camouflage for warships or other accessories to enhance the game-playing experience, within the games.

In accordance with ASC 605-45, Revenue Recognition: Principal Agent Considerations, the Group evaluates agreements with the game developers, distribution channels and payment channels in order to determine whether or not the Group acts as the principal or as an agent in the arrangement with each party respectively. The determination of whether to record the revenues gross or net is based on an assessment of various factors, including but not limited to whether the Group (i) is the primary obligor in the arrangement; (ii) has general inventory risk; (iii) changes the product or performs part of the services; (iv) has latitude in establishing the selling price; (v) has involvement in the determination of product and service specifications.

The Group records revenue generated from exclusive licensed mobile games on a gross basis as the Group is acting as the principal to fulfill all obligations related to the mobile game operation. The Group acts as the primary obligor, responsible for the launch of the game, hosting and maintenance of game servers and decides when and how to operate the in-game promotions and customer service. The Group is also determining the pricing of in-game virtual items and making a localized version for overseas licensed games.

Proceeds earned from selling in-game virtual items are shared between the Group and the game developers, with the amount paid to the developers generally calculated based on amounts paid by players, after deducting the fees paid to the payment channels and the distribution channels. Fees paid to game developers, distribution channels and payment channels are recorded as cost of revenues.

For the purposes of determining when the service has been provided to the end-users, the Group determined that an implied obligation exists to provide on-going services to the end-users who purchased virtual items to gain an enhanced game-playing experience over an average playing period of the paying players. Accordingly, the Group recognizes the revenues ratably over the estimated average playing period of these paying players, starting from the point in time when virtual items are delivered to the players' accounts and all other revenue recognition criteria are met.

The Group considers the average period that players typically play the games and other game player behavior patterns, as well as various other factors to arrive at the best estimates for the estimated playing period of the paying players for each game, usually from 3-6 months. To compute the estimated average playing period for paying users, the Group considers the initial purchase date as the starting point of a player's lifespan. The Group tracks populations of paying players who made their initial purchase during the 10-days interval period (the "cohort") and tracks each cohort to understand the number of players from each cohort who played the game after the initial purchase. To determine the ending point of a paying user's lifespan beyond the date for which observable data are available, the Company extrapolates the actual observed attrition rate to arrive at an estimated weighted average playing lifespan for paying users of the selected games. If a new game is launched and only a limited period of paying player data is available, then the Group considers other qualitative factors, such as the playing patterns for paying users for other games with similar characteristics and playing patterns of paying players, such as targeted players and purchasing frequency. While the Group believes its estimates to be reasonable based on available game player information, the Group may revise such estimates based on new information indicating a change in the game player behavior patterns and any adjustments are applied prospectively.

The Group is also offering publishing services for mobile games developed by third party game developers. For those jointly operated mobile games, the Group acted as a distribution channel that it will publish the games on its own app or website, named game portal. Through this game portal, game players can download the mobile games to their mobile devices and the Group earns game promotion service revenue by publishing them to the game players.

With respect to the jointly operated licensed arrangements between the Group and the game developer, the Group considered that the (i) developers are responsible for providing the game product desired by the game players; (ii) the hosting and maintenance of game servers for running the online mobile games is the responsibility of the developers; (iii) the developers have the right to change the pricing of in-game virtual items. The Group's responsibilities are publishing, providing payment solution and market promotion service, and thus the Group views the game developers to be its customers and considers itself as the agent of the game developers in the arrangements with game players. Accordingly, the Group records the game publishing service revenue from these games, net of amounts paid to the game developers.

The Group derives its advertising revenues principally from short-term online advertising contracts. Advertising service contracts may consist of multiple elements with a typical term of less than three months. Such elements generally represent different formats of advertisement, including but not limited to banners, text-links, videos, logos, buttons and rich media. Each element is time-based and the service period of the element is usually within three months. In accordance with ASU No.2009-13 Revenue Recognition—Multiple-Deliverable Revenue Arrangements ("ASU No.2009-13"), the Group treats advertising contracts with multiple deliverable elements as separate units of accounting for revenue recognition purposes and recognizes revenue over the advertising period during the contract when each deliverable elements of advertisements is provided and all the other revenue recognition criteria are met. Since the contract price is for all deliverables, the Group allocates the arrangement consideration to all deliverables at the inception of the arrangement on the basis of their relative selling price according to the selling price hierarchy established by ASU No.2009-13. The Group uses (a) vendor-specific objective evidence of selling price ("VSOE"), if it exists, otherwise, (b) third-party evidence of selling price. If neither (a) nor (b) exists, the Group will use (c) the management's best estimate of the selling price for that deliverable. As the deliverables are not sold separately, the best estimate of the selling price has taken into consideration of the pricing of advertising areas of the Group's platform with similar popularities and advertisements with similar formats and quoted prices from competitors and other market conditions The Group provides cash incentives in the form of sales rebate to certain advertising agencies, and accounts for such incentives as a reduction of revenue. The Group has estimated and recorded the rebates based on historical transactions and the rebate rate with certain advertising agencies.

The users can purchase virtual currency named "B-coin" via debit and credit cards or bank transfers via online payment systems provided by third party payment systems. The "B-coin" can be

used to purchase virtual items of live broadcasting and other valued added service. Each B-coin is worth RMB1. Proceeds received from the sales of "B-coin" are not refundable. Proceeds received from the sales of "B-coin" to users but not yet consumed are recorded as deferred revenues. Revenue is recognized upon conversion or consumption according to the respective prescribed revenue recognition policies addressed below.

The Group operates and maintains live broadcasting channel whereby users can enjoy live performances provided by the hosts and interact with the hosts. Most of the hosts host the performance on their own. The Group creates and sells virtual items to users so that the users present them simultaneously to hosts to show their support. The virtual items sold by the Group comprise of either (1) consumable items or (2) time-based item, such as privilege titles etc. Under the arrangements with the hosts, the Group shares with them a portion of the revenues derived from the sales of virtual items. Revenues derived from the sale of virtual items are recorded on a gross basis as the Group acts as the principal to fulfill all obligations related to the sale of virtual items. Accordingly, revenue is recognized when the virtual item is delivered and consumed if the virtual item is a consumable item or, in the case of time-based virtual item, recognized ratably over the period each virtual item is made available to the user, which does not exceed one year. The portion paid to hosts is recognized as cost of revenues. The other VAS includes sales of virtual items for video contents and membership subscription. Revenue from sales of virtual items, is recognized on item basis, which is consistent with the revenue recognition of live broadcasting. The membership revenue is recognized ratably over the period of the subscription when services are rendered.

Other revenues consist of other fee based premium services, which are mainly from the sales of products through the Group's e-commerce platform, as well as revenues from holding certain offline performance activities. Revenues are recognized when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable and collectability is reasonably assured. The Group evaluates whether it is appropriate to record the net amount earned as commissions or the gross amount of product sales. When the Group is not the primary obligor, doesn't bear the inventory risk and doesn't have the ability to establish the price, revenues are recorded on a net basis. When the Group is primarily obligated in a transaction, is subject to inventory risk, has latitude in establishing prices and selecting suppliers, or has several but not all of these indicators, revenues are recorded on a gross basis. Discount coupons to the customers for use in purchases are treated as a reduction of revenue when the related transaction is recognized.

The Group estimate revenue of mobile game, live broadcasting and other valued added service from the third-party payment processors in the current period when reasonable estimates of these amounts can be made. The processors provide reliable interim preliminary reporting within a reasonable time frame following the end of each month and the Group maintains records of sales data, both of which allow the Group to make reasonable estimates of revenue and therefore to recognize revenue during the reporting period. Determination of the appropriate amount of revenue recognized involves judgments and estimates that the Group believes are reasonable, but actual results may differ

from the Group's estimates. When the Group receives the final reports, to the extent not received within a reasonable time frame following the end of each month, the Group records any differences between estimated revenue and actual revenue in the reporting period when the Group determines the actual amounts. The revenue on the final revenue report have not differed significantly from the reported revenue for the periods presented.

Costs of revenues, consist primarily of revenue sharing costs to mobile games developers and distribution channels and payment channels, revenue sharing with the hosts, staff costs, content costs, servers and bandwidth service fees, depreciation expenses and other direct costs of providing these services as well as cost of merchandise sold. These costs are charged to the consolidated statements of operations and comprehensive loss as incurred.

Research and development expenses mainly consist of payroll-related expenses incurred for the innovation of video function, development and enhancement to the Company's websites and platforms of applications and development of online games.

For internal use software, the Group expenses all costs incurred for the preliminary project stage and post implementation-operation stage of development, and costs associated with repair or maintenance of the existing platform. Costs incurred in the application development stage are capitalized and amortized over the estimated useful life. Since the amount of the Company's research and development expenses qualifying for capitalization has been immaterial, as a result, all development costs incurred for development of internal used software have been expensed as incurred.

For external use software, costs incurred for development of external use software have not been capitalized since the inception of the Company, because the period after the date technical feasibility is reached and the time when the software is marketed is short historically, and the amount of costs qualifying for capitalization has been immaterial.

Sales and marketing expenses consist primarily of marketing and promotional expenses, salaries and other compensation-related expenses to the Group's sales and marketing personnel. Advertising expenses consist primarily of costs for the promotion of corporate image and product marketing. The Group expenses all advertising costs as incurred and classifies these costs under sales and marketing expenses. For the years ended December 31, 2015 and 2016, the advertising expenses were RMB11.0 million and RMB80.8 million, respectively.

Leases where substantially all the rewards and risks of ownership of assets remain with the lessor are accounted for as operating leases. Rental expense is recognized from the date of initial possession of the leased property on a straight-line basis over the term of the lease. Certain lease agreements contain rent holidays, which are recognized on a straight-line basis over the lease term. Lease renewal

periods are considered on a lease-by-lease basis and are generally not included in the initial lease terms. Rental expenses incurred by the Group were RMB12.9 million and RMB24.4 million for the years ended December 31, 2015 and 2016, respectively.

Share based compensation expenses arise from share based awards, including share options for the purchase of ordinary shares. The Company accounts for share-based awards granted to employees in accordance with ASC 718 Stock Compensation and share-based awards granted to nonemployees in accordance with ASC 505. For share options for the purchase of ordinary shares granted to employees determined to be equity classified awards, the related share-based compensation expenses are recognized in the consolidated financial statements based on their grant date fair values which are calculated using the binomial option pricing model. The determination of the fair value is affected by the share price as well as assumptions regarding a number of complex and subjective variables, including the expected share price volatility, actual and projected employee share option exercise behavior, risk-free interest rates and expected dividends. The fair value of the ordinary shares is assessed using the income approach/discounted cash flow method, with a discount for lack of marketability, given that the shares underlying the awards were not publicly traded at the time of grant. Share-based compensation expenses are recorded net of estimated forfeitures using straight-line method during the service period requirement, such that expenses are recorded only for those share-based awards that are expected to ultimately vest.

For shares options granted with service condition and the occurrence of an IPO as performance condition, cumulative share-based compensation expenses for the options that have satisfied the service condition will be recorded upon the completion of the IPO.

Share-based compensation expenses for share options granted to non-employees are measured at fair value at the earlier of the performance commitment date or the date service is completed, and recognized over the period during which the service is provided. The Group applies the guidance in ASC 505-50 to measure share options granted to non-employees based on the then-current fair value at each reporting date.

Full time employees of the Group in the PRC participate in a government mandated defined contribution plan, pursuant to which certain pension benefits, medical care, employee housing fund and other welfare benefits are provided to the employees. Chinese labor regulations require that the PRC subsidiaries and VIEs of the Group make contributions to the government for these benefits based on certain percentages of the employees' salaries, up to a maximum amount specified by the local government. The Group has no legal obligation for the benefits beyond the contributions made. The total amounts of such employee benefit expenses, which were expensed as incurred, were approximately RMB12.8 million and RMB44.3 million for the years ended December 31, 2015 and 2016, respectively.

Short-term investments include money market funds and investments in financial instruments with a variable interest rate referenced to performance of underlying assets.

In accordance with ASC 825, for investments in financial instruments with a variable interest rate referenced to performance of underlying assets, the Group elected the fair value method at the date of initial recognition and carried these investments at fair value. Changes in the fair value are reflected in the consolidated statements of operations and comprehensive loss as other income /(expenses). Fair value is estimated based on quoted prices of similar products provided by banks at the end of each period. The Group classifies the valuation techniques that use these inputs as Level 2 of fair value measurements. Please see Note 6 and Note 24 for additional information.

As of December 31, 2016 and 2015, all long-term investments are equity investments in privately held companies and they are individually not material. The majority of these investees are start-up Companies in China which operate in emerging industries or the industries to build on synergies with the Company such as game development, animation development and e-commerce platform.

For investments in an investee over which the Group does not have significant influence and which do not have readily determinable fair value, the Group carries the investment at cost and only adjusts for other-than-temporary declines in fair value and distributions of earnings that exceed the Group's share of earnings since its investment. Management regularly evaluates the impairment of the cost method investments based on performance and financial position of the investee as well as other evidence of market value. Such evaluation includes, but is not limited to, reviewing the investee's cash position, recent financing, projected and historical financial performance, cash flow forecasts and financing needs. An impairment loss recognized equal to the excess of the investment's cost over its fair value at the balance sheet date of the reporting period for which the assessment is made. The fair value would then become the new cost basis of investment.

In order to assess uncertain tax positions, the Group applies a more likely than not threshold and a two-step approach for the tax position measurement and financial statement recognition. Under the two-step approach, the first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. The Group recognizes interest and penalties, if any, under accrued expenses and other current liabilities on its consolidated balance sheet and under other expenses in its consolidated statement of operations and comprehensive loss. The Group did not have any significant unrecognized uncertain tax positions as of and for the years ended December 31, 2015 and 2016.

Parties are considered to be related if one party has the ability, directly or indirectly, to control the other party or exercise significant influence over the other party in making financial and operating decisions. Parties are also considered to be related if they are subject to common control or significant influence, such as a family member or relative, shareholder, or a related corporation.

Loss per share is computed in accordance with ASC 260, Earnings per Share. The two-class method is used for computing earnings per share in the event the Group has net income available for distribution. Under the two-class method, net income is allocated between ordinary shares and participating securities based on dividends declared (or accumulated) and participating rights in undistributed earnings as if all the earnings for the reporting period had been distributed. The Company's preferred shares are participating securities because they are entitled to receive dividends or distributions on an as converted basis. For the periods presented herein, the computation of basic loss per share using the two-class method is not applicable as the Group is in a net loss position and net loss is not allocated to other participating securities because in accordance with their contractual terms they are not obligated to share in the losses.

Basic net loss per share is computed using the weighted average number of ordinary shares outstanding during the period. Diluted net loss per share is computed using the weighted average number of ordinary shares and potential ordinary shares outstanding during the period under treasury stock method. Potential ordinary shares include options to purchase ordinary shares and preferred shares, unless they were anti-dilutive. The computation of diluted net income (loss) per share does not assume conversion, exercise, or contingent issuance of securities that would have an anti-dilutive effect (i.e. an increase in earnings per share amounts or a decrease in loss per share amounts) on net income (loss) per share.

In accordance with China's Company Laws, the Company's VIE in PRC must make appropriations from their after-tax profit (as determined under the accounting principals generally acceptable in the

People's Republic of China ("PRC GAAP")) to non-distributable reserve funds including (i) statutory surplus fund and (ii) discretionary surplus fund. The appropriation to the statutory surplus fund must be at least 10% of the after-tax profits calculated in accordance with PRC GAAP. Appropriation is not required if the statutory surplus fund has reached 50% of the registered capital of the respective company. Appropriation to the discretionary surplus fund is made at the discretion of the respective company.

Pursuant to the laws applicable to China's Foreign Investment Enterprises, the Company's subsidiary that is a foreign investment enterprise in China have to make appropriations from their after-tax profit (as determined under PRC GAAP) to reserve funds including (i) general reserve fund, (ii) enterprise expansion fund and (iii) staff bonus and welfare fund. The appropriation to the general reserve fund must be at least 10% of the after tax profits calculated in accordance with PRC GAAP. Appropriation is not required if the general reserve fund has reached 50% of the registered capital of the respective company. Appropriations to the other two reserve funds are at the respective companies' discretion.

The following table presents the Group's appropriations to general reserve funds and statutory surplus funds for the years ended December 31, 2015 and 2016:

Noncontrolling interests are recognized to reflect the portion of the equity of majority-owned subsidiaries of the Group's VIEs which is not attributable, directly or indirectly, to the controlling shareholder.

The noncontrolling interest will continue to be attributed with its share of losses even if that attribution results in a deficit noncontrolling interest balance.

Comprehensive income/(loss) is defined to include all changes in equity/(deficit) of the Group during a period arising from transactions and other events and circumstances excluding transactions resulting from investments by shareholders and distributions to shareholders. Other comprehensive (loss)/income, as presented on the consolidated balance sheets, consists of accumulated foreign currency translation adjustments.

Based on the criteria established by ASC 280 "Segment Reporting", the Group's chief operating decision maker has been identified as the Chairman of the Board of Directors/CEO, who reviews consolidated results of the Group when making decisions about allocating resources and assessing

performance. The Group has internal reporting of revenue, cost and expenses by nature as a whole. Hence, the Group has only one operating segment. The Company is domiciled in the Caymand Islands while the Group mainly operates its businesses in the PRC and earns substantially all of the revenues from external customers attributed to the PRC.

The Group accounts for its business combinations using the acquisition method of accounting in accordance with Accounting Standards Codification ("ASC") 805 "Business Combinations". The cost of an acquisition is measured as the aggregate of the acquisition date fair values of the assets transferred and liabilities incurred by the Group to the sellers and equity instruments issued. Transaction costs directly attributable to the acquisition are expensed as incurred. Identifiable assets and liabilities acquired or assumed are measured separately at their fair values as of the acquisition date, irrespective of the extent of any noncontrolling interests. The excess of (i) the total costs of acquisition, (ii) the fair value of the identifiable net assets of the acquiree is recorded as goodwill. If the cost of acquisition is less than the fair value of the net assets of the subsidiary acquired, the difference is recognized directly in the consolidated statements or operations and comprehensive loss. During the measurement period, which can be up to one year from the acquisition date, the Group may record adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the consolidated statements or operations and comprehensive loss.

For the Company's majority-owned subsidiaries and consolidated VIEs, a noncontrolling interest is recognized to reflect the portion of their equity which is not attributable, directly or indirectly, to the Company.

Revenue from Contracts with Customers. In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers (Topic 606)." This guidance supersedes current guidance on revenue recognition in Topic 605, "Revenue Recognition." In addition, there are disclosure requirements related to the nature, amount, timing, and uncertainty of revenue recognition. In August 2015, the FASB issued ASU 2015-14 to defer the effective date of ASU 2014-09 for all entities by one year. For publicly-traded business entities that follow U.S. GAAP, the deferral resulted in the new revenue standard being effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted for interim and annual periods beginning after December 15, 2016. The Group will apply the new revenue standard beginning January 1, 2018, and will not early adopt. The Group is currently in the process of analyzing each of the Group's revenue streams in accordance with the new revenue standard.

equity method of accounting or those that result in consolidation of the investee). This standard will be effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Group does not expect the adoption to have a material impact on its consolidated financial statements.

Leases. On February 25, 2016, the FASB issued ASU 2016-02, "Leases", which specifies the accounting for leases. For operating leases, ASU 2016-02 requires a lessee to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, in its balance sheet. The standard also requires a lessee to recognize a single lease cost, calculated so that the cost of the lease is allocated over the lease term, on a generally straight-line basis. In addition, this standard requires both lessees and lessors to disclose certain key information about lease transactions. ASU 2016-02 is effective for publicly-traded companies for annual reporting periods, and interim periods within those years, beginning after December 15, 2018. Early adoption is permitted. The Group is currently evaluating the impact of adopting this standard on its consolidated financial statements.

Compensation—Stock Compensation. On March 30, 2016, the FASB issued ASU 2016-09, "Compensation—Stock Compensation; Improvements to Employee Share-Based Payment Accounting", which relates to the accounting for employee share-based payments. This standard addresses several aspects of the accounting for share-based payment award transactions, including: (a) income tax consequences; (b) classification of awards as either equity or liabilities; and (c) classification on the statement of cash flows; (d) accounting for forfeitures of share-based payments. This standard will be effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The Group does not expect this standard to have a material impact on its consolidated financial statements. In May 2017, the FASB issued ASU 2017-09, "Compensation—Stock Compensation (Topic 718), Scope of Modification Accounting", which clarifies and reduces both (1) diversity in practice and (2) cost and complexity when applying the guidance in Topic 718, to a change to the terms or conditions of a share-based payment award. The amendments are effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption is permitted. The Group does not expect the adoption to have a material impact on its consolidated financial statements.

Statement of Cash Flows. In August 2016, the FASB issued ASU 2016-15, "Statement of Cash Flows—Classification of Certain Cash Receipts and Cash Payments", which clarifies the presentation and classification of certain cash receipts and cash payments in the statement of cash flows. This guidance is effective for financial statements issued for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The Group does not expect the adoption to have a material impact on its consolidated financial statements.

Business Combinations. In January 2017, the FASB issued ASU 2017-01, "Business Combinations (Topic 805): Clarifying the Definition of a Business", which clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions or disposals of assets or businesses. The standard is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. The standard should be applied prospectively on or after the effective date. The Group does not expect the adoption to have a material impact on its consolidated financial statements.

Simplifying the Test for Goodwill Impairment. In January 2017, the FASB issued ASU 2017-04 "Simplifying the Test for Goodwill Impairment." The guidance removes Step 2 of goodwill impairment tests, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit's carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. The guidance is to be adopted on a prospective basis for the annual or any interim goodwill impairment tests beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Group does not expect the adoption to have a material impact on its consolidated financial statements.

The Group relied on telecommunications service providers and their affiliates for servers and bandwidth service to support its operations during fiscal years 2015 and 2016 as follows:

Financial instruments that potentially subject the Group to significant concentrations of credit risk consist primarily of cash and cash equivalents, restricted cash, accounts receivable and short-term investments. As of December 31, 2015 and 2016, substantially all of the Group's cash and cash equivalents, and restricted cash were held in major financial institutions located in the United States of America or China, which management consider being of high credit quality. Accounts receivable is typically unsecured and is generally derived from revenue earned from mobile games services (mainly relates to remittances due from distribution channels) and advertising services. One distribution channel and one payment channel had a receivable balance exceeding 10% of the total accounts receivable balance of the Group for the years ended December 31, 2015 and 2016, respectively, as follows:

Short-term investments consist of money market funds and wealth management products issued by commercial banks in China with a variable interest rate referenced to performance of underlying assets, both have a maturity date within one year as of the purchase date.

No single customer represented 10% or more of the Group's total revenues for the years ended December 31, 2015 and 2016.

The Group relied on a distribution channel to publish and generate the iOS version of its mobile games revenues. For the years ended December 31, 2015 and 2016, approximately 13% and 22% of the Group's total net revenues.

The Group derived a combined total of 66% and 65% of its mobile game revenues for the years ended December 31, 2015 and 2016, respectively, from several its licensed mobile games, mainly include Fate/Grand Order ("FGO") and Yume-100. Revenue from these two games collectively accounted for 6% and 49% of our total mobile game revenue for the years ended December 31, 2015 and 2016.

The Group closely monitors the collection of its accounts receivables and records a reserve for doubtful accounts against aged accounts and for specifically identified non-recoverable amounts. If the economic situation and the financial condition of the customer deteriorate resulting in an impairment of the customer's ability to make payments, additional allowances might be required.

Receivable balances are written off when they are determined to be uncollectible. The following table sets out movements of the allowance for doubtful accounts for the years ended December 31, 2015 and 2016:

App stores retain commissions on each purchase made by the users through the App store. The Group is also obligated to pay ongoing licensing fees in the form of royalties to the games developed. Licensing fees consist of fees that the Group pay to content owners for the use of licensed content, including trademarks and copyrights, in the development of games. Licensing fees are either paid in advance and recorded on the balance sheet as prepayment or accrued as incurred and subsequently paid.

Additionally, the Group defers the revenue from licensed mobile games over the estimated average playing period of paying users given there is an implied obligation to provide on-going service to end-users. The related direct and incremental platform commissions as well as game developers' licensing fees are deferred and reported in "Prepayments and Other Current Assets" on the consolidated balance sheets.

As of December 31, 2015 and 2016, the Group's short-term investments consisted of wealth management products and investments in money market funds. These investments are recorded at fair value with changes in the fair value recorded in consolidated statements of operations and comprehensive loss directly.

During the years ended December 31, 2015 and 2016, the Group recorded investment income related to short-term investments of nil million and RMB12.3 million in the consolidated statements of operations and comprehensive loss, respectively.

As of December 31, 2015 and 2016, the Group's short-term investments consisted of money market funds and bank products issued by reputable commercial banks with variable interest rates referenced to the performance of the underlying investments and assets (mainly including cash, time deposits, and corporate debt securities).

Depreciation expenses were RMB5.7 million and RMB18.9 million for the years ended December 31, 2015 and 2016, respectively.

Amortization expenses were RMB36.5 million and RMB142.7 million for the years ended December 31, 2015 and 2016, respectively. No impairment charge was recognized for any of the periods presented.

As of December 31, 2016, the licensed copyrights of video content have weighted-average useful lives of 2.02 years. The intangible assets amortization expense for future years is expected to be as follows:

No impairment charge was recognized for the years ended December 31, 2015 and 2016.

As of December 31, 2016 and 2015, all long-term investments are equity investments in privately held companies. The Group carries the investments at cost as the Group does not have significant influence and the investments do not have readily determinable fair value.

The Company assesses its long-term investments accounted for under the cost method for other-than-temporary impairment by considering factors including, but not limited to, current economic and market conditions, operating performance of the companies, including current earnings trends and undiscounted cash flows, and other company-specific information, such as recent financing rounds. The fair value determination requires significant judgment to determine appropriate estimates and assumptions. Changes in these estimates and assumptions could affect the calculation of the fair value of the investments and the determination of whether any identified impairment is other-than-temporary. If any impairment is considered other-than-temporary, the Company will write down the asset to its fair value and take the corresponding charge to the consolidated statements of operations and comprehensive income.

No impairment provision was made for the years ended December 31, 2015 and 2016, respectively, as the Group determined that there was no decline in fair value, which was determined to be other-than-temporary.

The Group did not disclose the fair value of cost method investments as it is not practicable to estimate the fair value of its cost-method investments for which a quoted market price is not available due to both excessive cost as well as lack of available information on fair value of such investments. Specifically, many of the investees are start-up companies in China and operate in emerging industries for which the Group has not been able to estimate their fair values. Additionally, as the individual investees differ from each other, it was not practicable to estimate the fair value of the cost-method investments on a portfolio basis.

The following table presents the composition of income tax expenses for the years ended December 31, 2015 and 2016:

Under the current laws of the Cayman Islands, the Company, and its intermediate holding companies in the Cayman Islands are not subject to tax on income or capital gain. Additionally, upon payments of dividends by the Company or its subsidiaries in the Cayman Islands to their shareholders, no Cayman Islands withholding tax will be imposed.

Subsidiaries in the BVI are exempted from income tax on their foreign-derived income in the BVI. There are no withholding taxes in the BVI.

Subsidiaries in Hong Kong are subject to 16.5% income tax for 2015 and 2016 on their taxable income generated from operations in Hong Kong. The payments of dividends by these companies to their shareholders are not subject to any Hong Kong withholding tax.

On March 16, 2007, the National People's Congress of PRC enacted the Enterprise Income Tax Law, under which Foreign Invested Enterprises ("FIEs") and domestic companies would be subject to enterprise income tax ("EIT") at a uniform rate of 25%. Preferential tax treatments will continue to be granted to FIEs or domestic companies which conduct businesses in certain encouraged sectors and to entities otherwise classified as "Software Enterprises", "Key Software Enterprises" and/or "High and New Technology Enterprises" ("HNTEs"). The Enterprise Income Tax Law became effective on January 1, 2008.

The aforementioned preferential tax rates are subject to annual review by the relevant tax authorities in China. There is no preferential tax treatment for any entities of the Group for the years ended December 31, 2015 and 2016.

The following table presents a reconciliation of the differences between the statutory income tax rate and the Group's effective income tax rate for the years ended December 31, 2015 and 2016:

As of December 31, 2016, certain entities of the Group had net operating tax loss carry forwards as follows:

The Group's subsidiary and VIEs incorporated in China are subject to 6% value added tax ("VAT") for services rendered and 17% value added tax for goods sold.

The following table presents the tax impact of significant temporary differences that give rise to the deferred tax assets and liabilities as of December 31, 2015 and 2016:

The Group does not believe that sufficient positive evidence exists to conclude that the recoverability of deferred tax assets of certain entities of the Group is more likely than not to be realized. Consequently, the Group has provided full valuation allowances for certain entities of the

Group on the related deferred tax assets. The following table sets forth the movement of the aggregate valuation allowances for deferred tax assets for the periods presented:

The EIT Law also imposes a withholding income tax of 10% on dividends distributed by a foreign-invested entity ("FIE") to its immediate holding company outside of China, if such immediate holding company is considered as a non-resident enterprise without any establishment or place within China or if the received dividends have no connection with the establishment or place of such immediate holding company within China, unless such immediate holding company's jurisdiction of incorporation has a tax treaty with China that provides for a different withholding arrangement. Such withholding income tax was exempted under the Previous EIT Law. The Cayman Islands, where the Company incorporated, does not have such tax treaty with China. According to the arrangement between Mainland China and Hong Kong Special Administrative Region on the Avoidance of Double Taxation and Prevention of Fiscal Evasion in August 2006, dividends paid by a FIE in China to its immediate holding company in Hong Kong will be subject to withholding tax at a rate that may be lowered to 5% (if the foreign investor owns directly at least 25% of the shares of the FIE). The State Administration of Taxation ("SAT") further promulgated Circular 601 on October 27, 2009, which provides that tax treaty benefits will be denied to "conduit" or shell companies without business substance and that 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.

To the extent that subsidiaries and VIEs of the Group have undistributed earnings, the Company will accrue appropriate expected tax associated with repatriation of such undistributed earnings. As of December 31, 2015 and 2016, the Company did not record any withholding tax on the retained earnings of its subsidiary and VIE in the PRC as they were still in accumulated deficit position.

As of December 31, 2015, the short-term loans balance represents short-term loan arrangements with China Merchants Bank, with a fixed interest rate of 4.35% per annum and a maturity term of 12 months. As of December 31, 2015, the loan was secured by RMB deposits of the Group in an onshore branch of this bank in the amount of RMB10.1 million, which was recorded as restricted cash.

The following is a summary of accrued liabilities and other payables as of December 31, 2015 and 2016:

Deferred revenue primarily represents unamortized virtual items sold for mobile game services. Other deferred revenue includes prepaid subscription fees for internet value-added services for which the services are yet to be provided as of the balance sheet dates.

Since the inception, the Company issued Class A, Class B, Class C, and Class D ordinary shares. Class D, Class C and Class B ordinary shares holders have rights to convert their Class D, Class C and Class B ordinary shares into Class A ordinary shares on 1:1 ratio at any time after the date of issuance. Please refer to Note 1(a) for more detailed information.

According to the revised memorandum of association of the Company dated April 1, 2017, all the ordinary Shares held by founders shall have the right to ten votes for each outstanding ordinary Share held. Each of the ordinary Shares held by a person other than the founders and all Preferred Shareholders shall have the right to one vote for each outstanding ordinary Share or Preferred Share they held (on an as-converted basis).

No dividends or other distributions shall be made or declared, with respect to the Class A ordinary Shares and Class B ordinary Shares, unless and until dividends in like amount have been paid in full on the Preferred Shares, the Class C Ordinary Shares and Class D ordinary Shares (on an as-converted

basis); and no dividends or other distributions shall be made or declared, with respect to the Class A ordinary Shares, unless and until dividends in like amount have been paid in full on the Class B ordinary Shares (on an as-converted basis).

(a) The holders of Series C2, Series C1 and Series C Preferred Shares are entitled to receive an amount equal to their respective purchase price plus all declared but unpaid dividends, in preference to any distribution to any ordinary shareholders and any other Preferred Shareholders of the Company;

(b) After the full payment to the holders of Series C2, Series C1 and Series C Preferred Shares, the holders of Series B and Series A+ Preferred Shares and the holders of Class D Ordinary Shares are entitled to receive an amount equal to their respective purchase price plus all declared but unpaid dividends, and the holders of Series A Preferred Shares and the holders of Class C Ordinary Shares are entitled to receive an amount equal to 150% of their respective purchase price plus 8% annual compound return and all declared but unpaid dividends, in preference to any distribution to the holders of Class B and Class A Ordinary Shares of the Company;

(c) After the full payment to the holders of Series B, Series A+ and Series A Preferred Shares and the holders of Class D and Class C ordinary shares, the holders of Class B ordinary shares are entitled to receive an amount equal to 150% of purchase price plus 8% annual compound return and all declared but unpaid dividend;

(d) After the full payment to the holders of Class B ordinary shares, the remaining assets of the Company available for distribution to shareholders shall be distributed ratably among the holders of ordinary shares and preferred shares based on the number of Class A ordinary shares held by them on an as-converted basis.

Each Class B, Class C and Class D ordinary shares shall automatically be converted into Class A ordinary share i) upon the approval of the Ordinary Majority or (ii) upon the closing of a qualified IPO.

The Class B, C and Class D ordinary shares are preferred shares in nature as they have liquidation preference compared to Class A. The Company classifies Class B ordinary shares as permanent equity as they are not redeemable. Class C and Class D ordinary shares are redeemable upon certain liquidation events, including a change in control, which is deemed to be a liquidation event. However, as stipulated in the article of association of the Company, change in control will trigger the legal liquidation and termination of the Company, unless both majority of preferred shareholders and majority of ordinary shareholders otherwise agree on the exemption. Therefore, upon occurrence of the change in control, the Company will be liquidated and terminated, all the holders of equity shares of the Company are entitled to redeem, and form of consideration (cash or share) should be the same.

Accordingly, such liquidation feature meets the exception in ASC 480-10-S99-3A(f) and therefore Class C and Class D ordinary shares are classified as permanent equity in the consolidated balance sheets.

The Series A, A+, B, C, and C1/C2 Preferred Shares are collectively referred to as the "Preferred Shares".

The Preferred Shares are convertible, at the option of the holders, into the Company's ordinary shares at an initial conversion ratio of 1:1 at any time after the original issuance date. In the event that the Company issues additional ordinary shares at a price lower than the then-applicable conversion price for the Preferred Shares, the conversion price of the Preferred Shares shall be adjusted. The conversion prices are also subject to adjustments upon certain dilution events. In addition, the Preferred Shares are automatically convertible into such number of ordinary shares of the Company as shall be determined by reference to the then effective and applicable conversion ratio upon the earlier of (i) the closing of a qualified IPO as defined in the Memorandum and Articles of Association, or (ii) the date specified by written consent or agreement of holders of a majority of the outstanding Series A, A+, B, C, and C1/C2 Preferred Shares, each voting as a separate class.

Upon the issuance of Series B Preferred Shares, Series A+ and Series A Preferred Shares were modified to be redeemable, at the holder's discretion, at any time (i) after the five (5) year anniversary of the date on which Series B Preferred Shares were issued, and (ii) there is a material breach by any group company or any Founding Shareholder. The redemption price shall be (i) the respective issue price per share plus a seven percent (7%) annualized interest and all declared but unpaid dividends for Series B and Series A+ Preferred Shares, and (ii) one hundred and fifty percent (150%) of the issue price per share and all declared but unpaid dividends for Series A Preferred Shares.

Upon the issuance of Series C Preferred Shares, Series B, Series A+ and Series A Preferred Shares were modified to be redeemable, at the holder's discretion, at any time (i) after the five (5) year anniversary of the date on which Series C Preferred Shares were issued, and (ii) there is a material breach by any group company or any Founding Shareholder. The redemption price shall be (i) the respective issue price per share plus a seven percent (7%) annualized interest and all declared but unpaid dividends for Series C, Series B and Series A+ Preferred Shares, and (ii) one hundred and fifty percent (150%) of the issue price per share and all declared but unpaid dividends for Series A Preferred Shares.

The redemption price shall be (i) the respective issue price per share plus a seven percent (7%) annualized interest and all declared but unpaid dividends for Series C2, Series C1, Series C, Series B and Series A+ Preferred Shares, and (ii) one hundred and fifty percent (150%) of the issue price per share and all declared but unpaid dividends for Series A Preferred Shares.

The Company has classified the Preferred Shares in the mezzanine equity of the consolidated balance sheets. In addition, the Company records accretions on the Preferred Shares to the redemption value from the issuance dates to the earliest redemption dates. The accretions using the effective interest method, are recorded against retained earnings, or in the absence of retained earnings, by charges against additional paid-in capital. Once additional paid-in capital has been exhausted, additional charges are recorded by increasing the accumulated deficit. Each issuance of the Preferred Shares is recognized at the respective issue price at the date of issuance net of issuance costs. The issuance costs for Series A, Series A+, Series B, Series C, and Series C1/C2 Preferred Shares were RMB0.7 million, RMB1.9 million, RMB6.9 million, RMB13.5 million, and RMB13.4 million.

The Company recognized RMB22.3 million beneficial conversion feature attributable to Series A Preferred Share. The Company has determined that there was no beneficial conversion feature attributable to other preferred shares because the initial effective conversion prices of these preferred shares were higher than the fair value of the Company's common shares determined by the Company taking into account independent valuations.

The Group has classified all preferred shares as mezzanine equity in the consolidated balance sheet as they are contingently redeemable at the options of the holders.

Concurrent with the issuance of Series C Preferred Share in July 2015, the Company repurchased 6,085,754 Series A Preferred Shares held by Series A Preferred Shares investors, at the price of US$25.0 million (RMB152.9 million). The Company accounted for such repurchase as a retirement of treasury stock whereby the difference between the repurchase price and the carrying value of the Preferred Shares, of RMB 139.5 million, is accounted for as deemed dividend to the holders of Series A Preferred Shares which were recorded against additional paid-in capital and then to accumulated deficit after the balance of additional paid- in capital was wiped out.

Concurrent with the issuance of Series C1/C2 Preferred Shares in May 2016, the Company repurchased and cancelled 3,185,744 Series A Preferred Shares and 871,425 Series A+ Preferred Shares held by the investors, at the price of US$14.9 million (RMB98.9 million) and US$4.1 million (RMB27.1 million) respectively. The Company accounted for such repurchase as a retirement of treasury stock whereby the difference between the repurchase price and the carrying value of the Preferred Shares, of RMB 113.2 million in total, is accounted for as deemed to the holders of Series C1/C2 Preferred Shares which were recorded against additional paid-in capital and then to accumulated deficit after the balance of additional paid- in capital was wiped out.

The Company's subsidiaries and VIEs incorporated in China participate in a government-mandated multi-employer defined contribution plan under which certain retirement, medical, housing and other welfare benefits are provided to employees. Chinese labor regulations require the Company's Chinese subsidiaries and VIEs to pay to the local labor bureau a monthly contribution at a stated contribution rate based on the monthly basic compensation of qualified employees. The relevant local labor bureau is responsible for meeting all retirement benefit obligations; hence, the Group has no further commitments beyond its monthly contribution. The following table presents the Group's employee welfare benefits expenses for the years ended December 31, 2015 and 2016 (in millions):

In July 2014, the Group adopted its Global Share Incentive Plan (the "2014 Plan"), which permits the grant of options, restricted shares and restricted share units of the Company to relevant directors, officers, other employees and consultants of the Company and its affiliates. Option awards are granted with an exercise price determined by the Board of Directors. Those option awards generally vest over a period of four years and expire in six years.

The Group recognizes share-based compensation expenses in the consolidated statements of operations and comprehensive loss based on awards ultimately expected to vest, after considering estimated forfeitures. Forfeitures are estimated based on the Group's historical experience over the last five years and revised in subsequent periods if actual forfeitures differ from those estimates.

As of December 31, 2016, total unrecognized compensation expenses related to unvested awards granted under the 2014 Plan, adjusted for estimated forfeitures, was RMB79.8 million (US$12.0 million) which is expected to be recognized through the remaining vesting period of each grant. As of December 31, 2016, the weighted average remaining vesting period was 3.03 years.

The Group uses binomial option pricing model to determine fair value of the share-based awards. The estimated fair value of each option granted is estimated on the date of grant using the binomial option-pricing model with the following assumptions:

The expected volatility at the grant date and each option valuation date was estimated based on the annualized standard deviation of the daily return embedded in historical share prices of comparable peer companies with a time horizon close to the expected expiry of the term of the options. The weighted average volatility is the expected volatility at the grant date weighted by number of options. The Company has never declared or paid any cash dividends on its capital stock, and the Group does not anticipate any dividend payments in the foreseeable future. Expected term is the remaining contract life of options in the portfolio. The Group estimated the risk free interest rate based on the yield to maturity of U.S. treasury bonds denominated in US$ at the option valuation date.

The following table presents a summary of the Company's options activities for the years ended December 31, 2015 and 2016:

The weighted average grant date fair value of options granted for the years ended December 31, 2015 and 2016 was RMB12.3 (US$1.9) and RMB17.6 (US$2.5) per option, respectively.

As of December 31, 2016, there were RMB5.2 million of unrecognized share-based compensation expenses related to the share options granted with a performance condition of an IPO, out of which RMB1.0 million unrecognized share-based compensation expenses are related to options for which the service condition had been met and are expected to be recognized when the performance target of an IPO is achieved.

It is the Company's policy to issue new shares upon exercise of share options and vesting of RSUs. The number of shares available for future grant under the Company's 2014 Plan was 7,872,997 as of December 31, 2016.

The Company entered into following equity transactions with the Company's founders during the years ended December 31, 2015 and 2016, which involved share based compensation arrangements, therefore related share based compensation expenses were recorded:

Concurrent with the issuance of Series B and Series C Preferred Share in January and July 2015, the Company repurchased and cancelled 940,934 and 4,000,000 Class A ordinary shares held by the founders, who are employees of the Company, and 6,085,754 Series A Preferred Shares held by Series A Preferred Shares investors, at the price of US$1.8 million (RMB11.2 million), US$16.4 million (RMB100.5 million) and US$25.0 million (RMB152.9 million) respectively.

The Company accounted for such transactions as a retirement of treasury stocks, whereby 1) difference between the fair value and the par values of the ordinary shares, amounted to RMB51.9 million, was allocated to additional paid-in capital in the Company's consolidated balance sheets; and 2) difference between the repurchase price and the fair value of the ordinary shares, amounted to RMB59.8 million, was recorded as share based compensation expenses in the Company's consolidated statements of operations and comprehensive loss for the year ended December 31, 2015.

Additionally, in May 2016, the Company redesignated 1,104,535 Class A ordinary shares held by three founders into Series C1 Preferred Shares, and then transferred such 1,104,535 Series C1 Preferred Shares to another founder, who is employee of the Company, at par value. The Company did not receive any proceeds from this transaction.

The Company considers that such redesignation, in substance, is the same as a repurchase and cancellation of the ordinary shares and simultaneously a separate issuance of the preferred shares. Therefore the Company recorded 1) difference between the fair value and the par values of the ordinary shares as contribution; and 2) difference between the fair value of the preferred shares and the par value of the ordinary shares, amounted to RMB33.9 million, as share based compensation expenses in the Company's consolidated statements of operations and comprehensive loss for the year ended December 31, 2016.

In conjunction with the issuances of the Series A+ Preferred Shares in December 2014, 10,000,000 Class A ordinary shares redesignated from same number of Series A Preferred Shares were transferred to Mr. Rui Chen and became subject to an agreed vesting schedule provided that Mr. Rui Chen would continue his employment with the Group till the end of 2015. As a result, the Group recognized share based compensation expenses of RMB9.3 million in the Company's consolidated statements of operations and comprehensive loss for the year ended December 31, 2015.

Respectively in July 2015, May and December 2016, the Company issued 2,500,000, 2,000,000, 12,796,395 Class A ordinary shares to certain founders, who are employees of the Company, for free. Share based compensation expenses of RMB29.7 million and RMB283.8 million were recorded in the

Company's consolidated statements of operations and comprehensive loss for the years ended December 31, 2015 and 2016, respectively.

For the years ended December 31, 2015 and 2016, the Company had four categories for potential ordinary shares, the share options and Preferred Shares. As the Group incurred losses for the years ended December 31, 2015, and 2016, these potential ordinary shares were anti-dilutive and excluded from the calculation of diluted net loss per share of the Company. The numbers of share options and Preferred Shares excluded from the calculation of diluted net loss per share of the Company were 5,560,000, 87,871,201 as of December 31, 2015, and 12,572,109, 127,353,941 as of December 31, 2016, respectively.

Considering that the holder of Class B, Class C and Class D ordinary shares and Preferred Shares has no contractual obligation to participate in the Company's losses, any losses from the Group should not be allocated to the Class B, Class C and Class D ordinary shares and Preferred Shares.

The following table sets forth the computation of basic and diluted net loss per share for the years ended December 31, 2015 and 2016:

The Group leases office space and staff quarters under non-cancelable operating lease agreements, which expire at various dates through December 2024. As of December 31, 2016, future minimum lease

under non-cancelable operating lease agreements and other commitment related to purchases of platform content and services were as follows:

For the years ended December 31, 2015 and 2016, the Group incurred rental expenses in the amounts of approximately RMB12.9 million and RMB24.4 million, respectively.

From time to time, the Group is involved in claims and legal proceedings that arise in the ordinary course of business. Based on currently available information, management does not believe that the ultimate outcome of any unresolved matters, individually and in the aggregate, is reasonably possible to have a material adverse effect on the Group's financial position, results of operations or cash flows. However, litigation is subject to inherent uncertainties and the Group's view of these matters may change in the future. The Group records a liability when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. The Group reviews the need for any such liability on a regular basis. The Group has not recorded any material liabilities in this regard as of December 31, 2015 and 2016.

In 2016, the Group granted an interest free loan amounted to RMB5.0 million to Mr. Rui Chen, Chairman of the Board of Directors/CEO of the Company. The loan was fully repaid by Mr. Rui Chen in 2017 subsequently.

In 2016, the Group has completed the acquisition of Beijing Huarenyidian Technology Co., Ltd. ("Huarenyidian") and obtained 100% shareholding interest in Huarenyidian, of which 7% was transferred from Mr. Rui Chen, the Company's Chairman of the Board of Directors /CEO (See Note 26).

Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker ("CODM"), or decision making group, in deciding how to allocate resources and in assessing performance. The Group's CODM is the Mr. Rui Chen, Chairman of the Board of Directors/CEO.

The Group's organizational structure is based on a number of factors that the CODM uses to evaluate, view and run its business operations which include, but not limited to, customer base,

homogeneity of products and technology. The Group's operating segments are based on such organizational structure and information reviewed by the Group's CODM to evaluate the operating segment results. The Group has internal reporting of revenue, cost and expenses by nature as a whole. Hence, the Group has only one operating segment.

Substantially all revenues are derived from China based on the geographical locations where services are provided to customers. In addition, the Group's long-lived assets are substantially all located in China, and the amount of long-lived assets attributable to any individual other country is not material. Therefore, no geographical segments are presented.

When available, the Group uses quoted market prices to determine the fair value of an asset or liability. If quoted market prices are not available, the Group will measure fair value using valuation techniques that use, when possible, current market-based or independently sourced market parameters, such as interest rates and currency rates. The Group measures investments in money market funds and wealth management products at fair value.

Money market funds. The Group values its money market funds investments using observable inputs that reflect quoted prices for securities with identical characteristics, and accordingly, the Group classifies the valuation techniques that use these inputs as Level 1.

Wealth management products. The Group values its wealth management products investments held in certain banks or financial institutes using quoted prices for securities with similar characteristics and other observable inputs, and accordingly, the Group classifies the valuation techniques that use these inputs as Level 2.

Short-term bank loans. The carrying value of short-term bank loans approximates its fair value as the rates of interest under the loan agreements with the lending banks were determined based on the prevailing interest rates in the market. The Group classifies the valuation techniques that use these inputs as Level 2 of fair value measurements.

Accounts receivable and prepayments and other current assets are financial assets with carrying values that approximate fair value due to their short term nature. Accounts payable and other payables

are financial liabilities with carrying values that approximate fair value due to their short term nature. The Group classifies the valuation technique as Level 3 of fair value measurement, as it uses estimated cash flow input which is unobservable in the market.

Relevant PRC laws and regulations permit PRC companies to pay dividends only out of their retained earnings, if any, as determined in accordance with PRC accounting standards and regulations. Additionally, the Company's PRC subsidiaries and VIEs can only distribute dividends upon approval of the shareholders after they have met the PRC requirements for appropriation to the general reserve fund and the statutory surplus fund respectively. The general reserve fund and the statutory surplus fund require that annual appropriations of 10% of net after-tax income should be set aside prior to payment of any dividends. As a result of these and other restrictions under PRC laws and regulations, the PRC subsidiaries and VIEs are restricted in their ability to transfer a portion of their net assets to the Company either in the form of dividends, loans or advances, which restricted portion amounted to approximately RMB0.36 billion, or 23% of the Company's total consolidated net assets, as of December 31, 2016. Even though the Company currently does not require any such dividends, loans or advances from the PRC subsidiaries and VIEs for working capital and other funding purposes, the Company may in the future require additional cash resources from its PRC subsidiaries and VIEs due to changes in business conditions, to fund future acquisitions and developments, or merely declare and pay dividends to or distributions to the Company's shareholders.

In May 2016, the Group completed the acquisition of Huarenyidian by obtaining 100% shareholding interests of Huarenyidian, among which, 7% was acquired from Mr. Rui Chen Chairman of the Board of Directors /CEO of the Company and the remaining shareholding interests was acquired from third parties. Total consideration paid was RMB30.6 million in cash.

The Group made estimates and judgments in determining the fair value of business acquired taking into account independent valuations. The purchase price allocation is as follows:

In July 2016, the Group completed its acquisition of Children's Playground by obtained 100% shareholding interests in Children's Playground. The total consideration of the transaction is RMB28.4 million, comprising the cash consideration of RMB10.2 million and 1,000,000 share options issued to the original shareholders of Children's Playground.

The Group made estimates and judgments in determining the fair value of the business acquired taking into account independent valuations. The purchase price allocation is as follows:

Goodwill primarily represents the expected synergies from the combined operations of the acquired companies and the Group, the assembled workforce and their knowledge and experiences in game development and entertainment and media industry. The excess of purchase price over the fair value of net tangible assets and identifiable intangible assets acquired was recorded as goodwill. The goodwill is not expected to be deductible for tax purpose.

Pro forma results of operations for the acquisitions described above have not been presented because they are not material to the consolidated income statements for the years ended December 31, 2015 and 2016, either individually or in aggregate.

All of the Company's preferred shares and Class B, Class C and Class D ordinary shares will automatically be converted into ordinary shares at the applicable conversion price upon the earlier of (i) the date of closing of a qualified IPO as defined in the Memorandum and Articles of Association, or (ii) the date specified by written consent or agreement of holders of a majority of the outstanding preferred shares. The pro-forma balance sheet as of December 31, 2016 presents an adjusted financial position as if the conversion of the preferred shares into ordinary shares occurred on December 31, 2016.

The unaudited pro-forma loss per share for the year ended December 31, 2016 giving effect to the conversion of preferred shares and other permanent equities into ordinary shares as of the beginning of such year, is as follows:

On September 30, 2017, the Group completed the distribution of 100% of its interest in offline performance activities related business to the Company's shareholders and therefore the offline performance activities related business has been deconsolidated from the Group's consolidate financial statements. No gain or loss was recorded.
