ABOUT THIS PROSPECTUS SUPPLEMENT

        This prospectus supplement and the accompanying prospectus are part of a registration statement that we filed with the SEC using a "shelf" registration process. Under the shelf registration process, we may sell any combination of the securities described in the accompanying prospectus from time to time in one or more offerings, subject in certain cases to the receipt of regulatory approval. This document consists of two parts. The first part is this prospectus supplement, which describes the specific terms of this offering and other matters relating to us and our financial condition. The second part is the accompanying base prospectus, which gives more general information about securities we may offer from time to time. The base prospectus was included in the registration statement on Form F-3 (No. 333-250117) that we filed with the SEC on November 16, 2020 and may have been updated since that time with additional information that is incorporated by reference. The information in this prospectus supplement replaces any inconsistent information included in the accompanying prospectus. Generally, when we refer to the prospectus, we are referring to both parts of this document combined, and when we refer to the "accompanying prospectus," we are referring to the base prospectus. If information in this prospectus supplement differs from information in the accompanying prospectus, you should rely on the information in this prospectus supplement.

FORWARD-LOOKING STATEMENTS

        This prospectus supplement and the information incorporated by reference in the accompanying prospectus may contain forward-looking statements that involve risks and uncertainties. All statements other than statements of historical facts are forward-looking statements. These forward-looking statements are made under the "safe harbor" provisions of the U.S. Private Securities Litigation Reform Act of 1995. These statements involve known and unknown risks, uncertainties and other factors that 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:

•

our growth strategies;



•

our future business development, financial conditions and results of operations;



•

the trends in the e-commerce industry in China;



•

our expectations regarding demand for and market acceptance of our products and services;



•

our expectations regarding our relationships with buyers and merchants;



•

competition in our industry; and



•

relevant government policies and regulations relating to our industry.

        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. Other sections of this prospectus supplement and the accompanying prospectus include additional factors which could adversely impact our business and financial performance. Moreover, we operate in an evolving environment. New risk factors and uncertainties emerge from time to time and it is not possible for our management to predict all risk factors and uncertainties, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. Our actual results could be materially different from our expectations. You should read thoroughly this prospectus supplement 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 supplement contains certain data and information that we obtained from various government and private publications. We have not independently verified the accuracy or completeness of the data contained in these industry publications and reports. Statistical data in these publications also include projections based on a number of assumptions. The e-commerce 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 e-commerce 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.

RISK FACTORS

        An investment in our ADSs involves risks. Before you decide to buy these securities, you should consider carefully all of the information in this prospectus supplement as well as the section titled "Risk Factors" included in the accompanying prospectus and all the documents incorporated therein by reference, including the factors set forth under "Item 3. Key Information—D. Risk Factors" in our 2019 Annual Report. Any of these risks could have a material adverse effect on our business, prospects, financial condition and results of operations. In any such case, the trading price of our ADSs could decline, and you could lose all or part of your investment. Please see "Where You Can Find More Information About Us" and, in the accompanying prospectus, "Incorporation of Documents by Reference" for information on where you can find the documents we have filed with or furnished to the SEC and which are incorporated into the accompanying prospectus by reference.

Risks Related to Our Business and Industry

Our limited operating history makes it difficult to evaluate our business and prospects. We cannot guarantee that we will be able to maintain the growth rate that we have experienced to date.

        We commenced our commercial operations in 2015, and have a limited operating history. The number of our active buyers have grown exponentially to reach approximately 731.3 million in the twelve-month period ended September 30, 2020. Our revenues grew from RMB19,349.2 million in the nine months ended September 30, 2019 to RMB32,944.2 million (US$4,852.2 million) in the same period in 2020. However, our historical performance may not be indicative of our future growth or financial results. We cannot assure you that we will be able to grow at the same rate as we did in the past, or avoid any decline in the future. Our growth may slow down or become negative, and revenues may decline for a number of possible reasons, some of which are beyond our control, including decreasing consumer spending, increasing competition, declining growth of our overall market or industry, the emergence of alternative business models, changes in rules, regulations, government policies or general economic conditions. In addition, our online marketing services, from which we have generated almost all of our revenues since 2017, are a relatively new initiative and may not grow as quickly as we have anticipated. It is difficult to evaluate our prospects, as we may not have sufficient experience in addressing the risks to which companies operating in rapidly evolving markets may be exposed. If our growth rate declines, investors' perceptions of our business, operating results and prospects may be materially and adversely affected and the market price of our ADSs could decline. You should consider our prospects in light of the risks and uncertainties that companies with a limited operating history may encounter.

If we fail to anticipate buyer needs and provide products and services to attract and retain buyers, or fail to adapt our services or business model to changing buyer needs or emerging industry standards, our business may be materially and adversely affected.

        The e-commerce market in which we operate as well as buyer needs and preferences are constantly evolving. As a result, we must continuously respond to changes in the market and buyer demand and preferences to remain competitive, grow our business and maintain our market position. We intend to further diversify our product and service offerings to add to our revenue sources in the future. New products and services, new types of buyers or new business models may involve risks and challenges we do not currently face. Any new initiatives may require us to devote significant financial and management resources and may not perform as well as expected. For example, the e-waybill system we launched in the first quarter of 2019, the livestreaming initiative we launched in January 2020 and the Duo Duo Maicai initiative we started in August 2020, each may require financial, personnel and other resources commitment over time and may not attract or retain enough users or otherwise perform in accordance with our expectations. Furthermore, we may have difficulty in anticipating buyer demand and preferences, and the products offered on our platform may not be accepted by the market

or be rendered obsolete or uneconomical. Therefore, any inability to adapt to these changes may result in a failure to capture new buyers or retain existing buyers, the occurrence of which would materially and adversely affect our business, financial condition and results of operations.

        In addition, to remain competitive, we must continue to enhance and improve the responsiveness, functionality and features of our platform. The internet and e-commerce markets are characterized by rapid technological evolution, changes in buyer requirements and preferences, frequent introductions of new products, features and services embodying new technologies and the emergence of new industry standards and practices, any of which could render our existing technologies and systems obsolete. Our success will depend, in part, on our ability to identify, develop and adapt to new technologies useful in our business, and respond to technological advances and emerging industry standards and practices, in particular with respect to mobile internet, in a cost-effective and timely way. We cannot assure you that we will be successful in these efforts.

Any harm to our brand or reputation may materially and adversely affect our business and results of operations.

        We believe that the recognition and reputation of our Pinduoduo or " " brand among our buyers, merchants and third-party service providers have contributed significantly to the growth and success of our business. Maintaining and enhancing the recognition and reputation of our brand are critical to our business and competitiveness. Many factors, some of which are beyond our control, are important to maintaining and enhancing our brand. These factors include our ability to:

•

provide a superior shopping experience to buyers;



•

maintain the popularity, attractiveness, diversity, quality and authenticity of our product offerings;



•

maintain the efficiency, reliability and quality of the fulfillment and delivery services to our buyers;



•

maintain or improve buyers' satisfaction with our after-sale services;



•

increase brand awareness through marketing and brand promotion activities; and



•

preserve our reputation and goodwill in the event of any negative publicity on our consumer experience or merchant service, internet and data security, product quality, price or authenticity, performance measures, or other issues affecting us or other e-commerce businesses in China.

        Public perception that counterfeit, unauthorized, illegal, or infringing products are sold on our platform or that we or merchants on our platform do not provide satisfactory consumer services, even if factually incorrect or based on isolated incidents, could damage our reputation, diminish the value of our brand, undermine the trust and credibility we have established and have a negative impact on our ability to attract new buyers or retain our current buyers. In particular, we have been and may continue to be subject to negative publicity based on claims and allegations related to intellectual property. For example, the Office of the U.S. Trade Representative, or USTR, identified our platform as a "notorious market" in the 2019 and 2020 Annual Special 301 Reports. The USTR may continue to identify our platform as a notorious market in the future. The negative public perception resulted therefrom could damage our reputation, harm our business, diminish the value of our brand name and negatively affect trading price of our ADSs.

        If we are unable to maintain our reputation, enhance our brand recognition or increase positive awareness of our platform, products and services, it may be difficult to maintain and grow our buyer base, and our business and growth prospects may be materially and adversely affected.

Our merchants use a variety of third-party logistics service providers and e-waybill systems. Service interruptions, failures, or constraints of these logistics service providers or any disruptions or malfunctions of the e-waybill systems could severely harm our business and prospects.

        The merchandise on our platform are supplied and shipped directly from our merchants to our buyers. Our merchants use third-party logistics service providers to fulfill and deliver their orders. Interruptions to or failures in third-party logistics services could prevent timely and successful delivery of the ordered products to our buyers. As we do not directly control or manage the operations of these third-party logistics service providers, we may not be able to guarantee their performance. Any failure to provide satisfactory services to our buyers, such as delays in delivery, product damage or product loss during transit, may damage our reputation and cause us to lose buyers, and may ultimately adversely affect our results of operations. In addition, certain of these third-party logistics service providers may be influenced by our competitors when providing services to us. For example, if third-party logistics service providers raise the shipping rates for delivering products of merchants on our platform, our merchants may not be willing to bear the increased costs or be able to offer competitive prices for products on our platform. As a result, our business and prospects, as well as our financial condition and results of operations could be materially and adversely affected.

        If the third-party logistics service providers used by our merchants fail to deliver products to our buyers on time or deliver products in good conditions, our buyers may refuse to accept merchandise purchased on our platform and have less confidence in our platform. In such event, we cannot assure you that our merchants will be able to find alternative cost-efficient logistics service providers to offer satisfactory delivery services in a timely manner, or at all, which could cause our business and reputation to suffer or cause merchants to move to other platforms and have negative impact on our financial conditions.

        Most merchants use e-waybill systems to arrange and track shipment. While we launched our e-waybill system during the first quarter of 2019, the merchants on our platform are allowed to choose different e-waybill systems. Any disruptions or malfunctions of e-waybill systems used by our merchants could prevent the timely or proper delivery of products to consumers, which would damage our reputation, harm our business, diminish the value of our brand name.

We face intense competition, and if we fail to compete effectively, we may lose market share, buyers and merchants.

        The e-commerce industry in China is intensely competitive. We compete to attract, engage and retain buyers, merchants, and other participants on our platforms. Our current or potential competitors include (i) major e-commerce companies in China, (ii) major traditional and brick-and-mortar retailers in China, (iii) retail companies in China focused on specific product categories and (iv) major internet companies in China that do not operate e-commerce businesses now but may enter the e-commerce business area or are in the process of initiating their e-commerce businesses. These current or future competitors may have longer operating histories, greater brand recognition, better supplier or merchant relationships, stronger infrastructure, larger buyer bases or greater financial, technical or marketing resources than we do. Competitors may leverage their brand recognition, experience and resources to compete with us in a variety of ways, including making investments and acquisitions for the expansion of their product and service offerings. Some of our competitors may be able to secure more favorable terms from merchants, devote greater resources to marketing and promotional campaigns, adopt more aggressive pricing or inventory policies and devote substantially more resources to develop their IT systems and technology. Some of these competitors may also offer "team purchase" on their platforms or offer innovative purchase models that may turn out to be highly popular among buyers, and buyers may prefer them over our team purchase model. In addition, new and enhanced technologies may increase the competition in the market we operate in. Increased competition may reduce our profitability, market share, user base and brand recognition. There can be no assurance that we will be

S-18

Table of Contents

able to compete successfully against current or future competitors, and such competitive pressures may have a material and adverse effect on our business, financial condition and results of operations.

If we fail to maintain and expand our relationships with merchants, our revenues and results of operations will be harmed.

        We rely on our merchants to offer merchandise that appeal to our existing and potential buyers at attractive prices. Our ability to provide popular products on our platform at attractive prices depends on our ability to develop mutually beneficial relationships with our merchants. For example, we rely on our merchants to make available sufficient inventory and fulfill large volumes of orders in an efficient and timely manner to ensure our user experience. To date, our buyers and merchants have been increasing in parallel as a result of the powerful network effects of our platform. However, we may experience merchant attrition in the ordinary course of business resulting from several factors, such as losses to competitors, perception that marketing on our platform is ineffective, reduction in merchants' marketing budgets, and closures or bankruptcies of merchants. In addition, we may have disputes with merchants with respect to their compliance with our quality control policies and measures and the penalties imposed by us for violation of these policies or measures from time to time, which may cause them to be dissatisfied with our platform. Their complaints may in turn result in negative impact on our public image and reputation. If we experience significant merchant attrition, or if we are unable to attract new merchants, our revenues and results of operations may be materially and adversely affected. In addition, our agreements with merchants also typically do not restrict them from establishing or maintaining business relationships with our competitors. We cannot assure you that merchants will continue to offer merchandise on our platform if they are pressured to use only one platform to market their products.

Any change, disruption, discontinuity in the features and functions of major social networks could severely limit our ability to continue growing our buyer base, and our business may be materially and adversely affected.

        Our success depends on our ability to attract and retain new buyers and expand our buyer base. Acquiring and retaining buyers on our platform is important to the growth and profitability of our business. We leverage social networks as a tool for buyer acquisition and engagement. Although buyers can access our platform and make team purchases directly through our Pinduoduo mobile app, we leverage social networks, such as Weixin and QQ, to enable buyers to share product information and their purchase experiences with their friends, family and other social contacts to generate effective and organic traffic and active interactions among buyers. A portion of our buyer traffic comes from such user recommendation or product introduction feature which buyers can share with friends or contacts through social networks. Due to the nature of our business model, which resembles a dynamic and interactive shopping experience, it is impracticable for us to accurately bifurcate and quantify the buyer traffic generated directly through our platform and through social networks. Therefore, during our daily operations, we focus more on the GMV on our platform as a whole and the seamless user experience across different access points, and believe that the final purchase destination cannot be used to reflect the significance of social networks and our Pinduoduo mobile app to our business operations.

        To the extent that we fail to leverage such social networks, our ability to attract or retain buyers may be severely harmed. If any of these social networks makes changes to its functions or support, such as charging fees for functions or support that is currently provided for free, or stops offering its functions or support to us, we may not be able to locate alternative platforms of similar scale to provide similar functions or support on commercially reasonable terms in a timely manner, or at all. Furthermore, we may fail to establish or maintain relationships with additional social network operators to support the growth of our business on economically viable terms, or at all. Any interruption to or discontinuation of our relationships with major social network operators may severely and negatively

impact our ability to continue growing our buyer base, and any occurrence of the circumstances mentioned above may have a material adverse effect on our business, financial condition and results of operations.

We are dependent on app stores to disseminate our mobile apps.

        We offer our services mainly through our Pinduoduo mobile platform. Our mobile apps are offered via smartphone and tablet apps stores operated by third parties, such as Apple's App Store, which could suspend or terminate users' access to our mobile apps, increase access costs or change the terms of access in a way that makes our apps less desirable or harder to access. As a result, our ability to expand our user base may be hindered if potential users experience difficulties in or are barred from accessing our mobile apps. In the past, our mobile apps were taken down from certain third-party app stores for a short period of time. We cannot assure you that we will not experience such incident of similar nature in the future. The occurrence of the similar incident may adversely affect our brand and reputation, business, financial condition and results of operations.

Any disruption to our IT systems could materially affect our ability to maintain the satisfactory performance of our IT systems and deliver consistent services to our buyers and merchants.

        The proper functioning of our IT systems is essential to our business. The satisfactory performance, reliability and availability of our IT systems are critical to our success, our ability to attract and retain buyers and our ability to maintain and deliver consistent services to our buyers and merchants. However, our technology infrastructure may fail to keep pace with increased sales on our platform, in particular with respect to our new product and service offerings, and therefore our buyers may experience delays as we seek to source additional capacity, which would adversely affect our results of operations as well as our reputation.

        Additionally, we must continue to upgrade and improve our technology infrastructure to support our business growth. However, we cannot assure you that we will be successful in executing these system upgrades, and the failure to do so may impede our growth. We currently rely on cloud services and servers operated by external cloud service providers to store our data, to allow us to analyze a large amount of data simultaneously and to update our buyer database and buyer profiles quickly. Any interruption or delay in the functionality of these external cloud service and server providers may materially and adversely affect the operations of our business.

        We may be unable to monitor and ensure high-quality maintenance and upgrade of our IT systems and infrastructure on a real-time basis, and buyers may experience service outages and delays in accessing and using our platform to place orders. In addition, we may experience surges in online traffic and orders associated with promotional activities and generally as we scale, which can put additional demand on our platform at specific times. Our technology or infrastructure may not function properly at all times. Any system interruptions caused by telecommunications failures, computer viruses, hacking or other attempts to harm our systems that result in the unavailability or slowdown of our platform or reduced order fulfillment performance could reduce the volume of products sold and the attractiveness of product offerings on our platform. Our servers may also be vulnerable to computer viruses, physical or electronic break-ins and similar disruptions, which could lead to system interruptions, mobile app slowdown or unavailability, delays or errors in transaction processing, loss of data or the inability to accept and fulfill buyer orders. Any of such occurrences could cause severe disruption to our daily operations. As a result, our reputation may be materially and adversely affected, our market share could decline and we could be subject to liability claims.

We have incurred net losses in the past, and we may continue to incur losses in the future.

        We have incurred net losses since our inception. We incurred net loss of RMB5,803.4 million (US$854.7 million) in the nine months ended September 30, 2020, compared to net loss of RMB5,216.0 million in the nine months ended September 30, 2019. We cannot assure you that we will be able to generate net profits in the future. In addition, we expect our operating costs and expenses to increase in absolute amounts in the future due to: (i) the continued expansion of our business operations, buyer base and merchant network, (ii) the continued investment in technology infrastructure and network, (iii) our promotion and marketing efforts as we continue to enhance our brand recognition, retain and grow our buyer base, and increase our buyer activities, (iv) the launch of new services, and (v) the investment in new initiatives, which may incur upfront costs, change our existing revenue and cost structures, and affect our ability to achieve profitability.

        Our ability to achieve profitability depends on our ability to, among other things, increase our number of active buyers, grow and diversify our merchant base, and optimize our cost structure. We may not be able to achieve any of the above. In particular, our sales and marketing expenses increased substantially from RMB17,901.7 million in the nine months ended September 30, 2019 to RMB26,482.1 million (US$3,900.4 million) in the nine months ended September 30, 2020, as we invested in cultivating greater user recognition and engagement through online and offline advertising campaigns and promotions. If we continue to incur substantial sales and marketing expenses without being able to achieve the anticipated buyer and merchant growth, our operating results may be materially and adversely affected. As a result, we may fail to improve our operating margin, and may continue to incur net losses in the future. In addition, our ability to use our net losses to offset future taxable income may be subject to certain limitations, including limitations resulting from reorganization of our corporate structure and change of our primary operating entities. As such, we may not be able to fully utilize our net losses or at all, even if we were to achieve profitability.

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

        We rely on certain key operating metrics, such as GMV, 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. If these metrics are perceived to be inaccurate by investors or investors make investment decisions based on operating metrics we disclosed but with their own methodology and assumptions or those published or used by third parties or other companies, our reputation may be harmed, which could negatively affect our business, and we may also face potential lawsuits or disputes.

We face risks related to natural disasters, health epidemics and other outbreaks, most notably those related to the outbreak of COVID-19, which could significantly disrupt our operations.

        We and our merchants are vulnerable to natural disasters, health epidemics, and other calamities. Any of such occurrences could cause severe disruption to the daily operations of us and our merchants and may even require a temporary closure of facilities and logistics delivery networks, which may disrupt our business operations and adversely affect our results of operations. In recent years, there have been outbreaks of epidemics in China and globally. For example, in early 2020, in efforts to contain the spread of COVID-19, the Chinese government took a number of actions, which included extending the Chinese New Year holiday, quarantining individuals suspected of having COVID-19, and asking residents in China to stay at home and to avoid public gathering, among other things. COVID-19 has also resulted in temporary closure of many corporate offices, retail stores, and manufacturing facilities and factories across China, and put significant strain on merchandise shipping and delivery. Reduction in product offering on our e-commerce platform and delay in delivery caused by the impairment of manufacturing and delivery capacity of our merchants and services providers may

Table of Contents

damage our reputation and cause us to lose buyers, and adversely affect our results of operations. While the events related to the outbreak of and response to the COVID-19 may be temporary and many of the COVID-19 quarantine measures within China have since been significantly relaxed as of the date of this prospectus supplement, the duration of the business disruption and the financial impact resulting from the outbreak of COVID-19 will likely negatively affect our financial results for the remainder of 2020, and their impact on our financial performance for the period beyond 2020 cannot be reasonably estimated at this time. The extent to which the outbreak of COVID-19 impacts our results will depend on future developments, which are highly uncertain and cannot be predicted, including new information which may emerge concerning the severity of this outbreak and the actions to contain this outbreak or treat its impact, among others. In addition, our results of operations could be adversely affected to the extent that any epidemics or other catastrophic events, such as COVID-19, harm the Chinese economy in general.

Our success depends on the continuing efforts of our key employees. If we fail to hire, retain and motivate our key employees, our business may suffer.

        Our future success is significantly dependent upon the continued service of our key executives and other key employees. If we lose the services of any member of our management or key personnel, we may not be able to locate suitable or qualified replacements, and may incur additional expenses to recruit and train new staff, which could severely disrupt our business and growth. Our founder and chairman of the board of directors, Mr. Zheng Huang, our chief executive officer, Mr. Lei Chen, and other management members are critical to our vision, strategic direction, culture and overall business success. If there is any internal organizational structure change or change in responsibilities for our management or key personnel, the operation of our business and our business prospects may be adversely affected. Our employees, including members of our management, may choose to pursue other opportunities. If we are unable to motivate or retain key employees, our business may be severely disrupted and our prospects could suffer.

        The increasing scale of our business also requires us to hire and retain a wide range of capable and experienced personnel and technology talents who can adapt to a dynamic, competitive and challenging business environment. Competition for talents is intense, and the availability of suitable and qualified candidates in China is limited. Competition for talents could cause us to offer higher compensation and other benefits to attract and retain them. Even if we were to offer higher compensation and other benefits, these individuals may not choose to join or continue to work for us. Any failure to attract or retain key management and personnel could severely disrupt our business and growth.

If we are unable to manage our growth or execute our strategies effectively, our business and prospects may be materially and adversely affected.

        Our business has grown substantially since our inception, and we expect continued growth in our business, revenues and number of employees. We have significantly expanded our headcount and office facilities, and we anticipate that further expansion in certain areas and geographies will be required. This expansion increases the complexity of our operations and places a significant strain on our management, operational and financial resources. The expansion may cause additional risks and costs in relation to compliance, such as dealing with regulatory enforcement or labor disputes. We must continue to hire, train and effectively manage new employees. If our new hires perform poorly or if we are unsuccessful in hiring, training, managing and integrating new employees, our business, financial condition and results of operations may be materially harmed.

        In addition, we plan to further establish relationships with more merchants to increase the product offerings on our platform. Such expansion may require us to introduce new products and work with a variety of additional merchants to address the evolving needs of our buyers. We may have limited or no

S-22

Table of Contents

experience for certain new product offerings, and our expansion into these new product offerings may not achieve broad buyer acceptance. These offerings may present new and difficult technological or operational challenges, and we may be subject to claims if buyers are not satisfied with the quality of the products or do not have satisfactory experiences in general.

        To effectively execute our business strategies and manage the expected growth of our operations and personnel, we will need to continue to improve our transaction processing, technological, operational and financial systems, policies, procedures and controls. For example, the e-waybill system that we launched in the first quarter of 2019, the livestreaming feature that we started in January 2020, and the Duo Duo Maicai initiative that we started in August 2020, each may require financial personnel and other resources commitment over time, including recruitment of employees, development of new technologies, launch of additional promotional activities and investments in fulfillment infrastructure. All of these endeavors involve risks and will require significant management, financial and human resources. We cannot assure you that we will be able to effectively manage our growth or to implement our strategies successfully. If we are not able to manage our growth or implement our strategies effectively, or at all, our business and prospects may be materially and adversely affected. For example, we have developed an open, asset-light logistics technology platform. As the first pillar to such logistics technology platform, we launched our e-waybill system during the first quarter of 2019. Building on top of our e-waybill system, our aim is to build a platform that would provide technology solutions to our sizable and growing merchant base, and fundamentally improve their efficiencies and services to users as we deepen our relationships with them through C2M, cross-border e-commerce, and other initiatives. As a result of the development of this platform, we may incur additional costs and expenses, devote more management's attention to its operations and compliance and allocate additional resources in dealing with potential disputes relating to its operations and intellectual property rights.

We may incur liability for counterfeit, unauthorized, illegal, or infringing products sold or misleading information available on our platforms.

        Under our current marketplace model, all products offered on our platform are supplied by merchants, who are separately responsible for sourcing and coordinating delivery of the products that are sold on our platform. In 2019, we had 5.1 million active merchants on our platform, offering a broad range of product categories. We have been and may continue to be subject to allegations and lawsuits claiming that products listed or sold through our platform by third-party merchants are counterfeit, unauthorized, illegal, or otherwise infringe third-party copyrights, trademarks, patents or other intellectual property rights, or that content posted on our user interface contains misleading information on description of products and comparable prices. Although we have adopted strict measures to protect us against these potential liabilities, including but not limited to, proactively verifying the authenticity and authorization of products sold on our platform through working with brands and conducting offline investigations, blocking prior to product launch or immediately taking down any counterfeit or illegal products or misleading information found on our platform, closing higher-risk online stores, and freezing the accounts of merchants in violation of the platform policies, these measures may not always be successful or timely. For example, in January 2018, we were required by the relevant government authorities to strengthen supervision on the qualifications of the distributors of publications on our platform and to respond effectively to claims of copyright infringement. We have taken a number of measures in accordance with such requirements including the implementation of a comprehensive system in reviewing and tracking the qualification status of the relevant merchants. In August 2018, we met with the officials from the relevant governmental authorities to discuss the alleged sale of counterfeit and infringing products on our platform upon their request. Shortly after the meetings, we adopted a number of remediation measures including more rigorous policies of closure of stores and removal of listings with infringing products from our platform. We may implement further measures in an effort to eliminate infringing products on our platforms, including taking legal actions against merchants of counterfeit or infringing products, which may cause

S-23

Table of Contents

us to spend substantial additional resources or result in reduced revenues. In addition, these measures may not appeal to consumers, merchants or other participants on our platforms. A merchant whose account is suspended or terminated by us, regardless of our compliance with the applicable laws, rules and regulations, may have disputes with us and commence action against us for damages, make public complaints or engage in publicity campaigns against us. We may incur significant costs to defend against these activities, which could harm our business.

        In the event that counterfeit, illegal, unauthorized or infringing products are sold on our platform or infringing or misleading content is posted on our user interface, we could face claims or be imposed penalties. Counterfeit products sold on our platform may damage our reputation and cause buyers to refrain from making future purchases from us, which would materially and adversely affect our business operations and financial results. We have in the past received claims alleging the sales of defective, counterfeit or unauthorized items on our platform. For example, in July 2018, a complaint was filed against us in U.S. federal court alleging contributory trademark infringement and unfair competition based on certain allegedly counterfeit and unauthorized merchandise sold by merchants to U.S. consumers on our platform. In August 2019, the court granted our motion to dismiss the plaintiff's complaint and dismissed all claims against us on the ground that the court lacked personal jurisdiction. In February 2020, the court awarded us attorney's fees and costs due to the plaintiff's frivolous and problematic claims. Irrespective of the validity of such claims, we could incur significant costs and efforts in either defending against or settling such claims. If there is a successful claim against us in the United States, we might be required to pay substantial damages or be enjoined from permitting further sale of the relevant products or activities by certain merchants. Potential liabilities under PRC law for negligence in participating or assisting in infringement activities associated with counterfeit goods include injunctions to cease infringing activities, rectification, compensation, administrative penalties and even criminal liability.

        Moreover, the alleged sales of counterfeit products and third-party claims or administrative penalties related to them could result in significant negative publicity and our reputation could be severely damaged. For example, the Office of the U.S. Trade Representative, or USTR, identified our platform as a "notorious market" in the 2019 and 2020 Annual Special 301 Reports. The USTR may continue to identify our platform as a notorious market in the future. The negative public perception resulted therefrom could damage our reputation, harm our business, diminish the value of our brand name and negatively affect trading price of our ADSs.

        Some of our merchants interact and exchange information with our users through our livestreaming feature. As such communication is conducted in real time, we are unable to verify the information exchanged. Therefore, it is possible that users may engage in conversations or activities with illegal, obscene or infringing content that may be deemed unlawful under PRC laws and regulations on our platform. In addition, certain merchants may post and sell on our platform products that may not be sold via e-commerce platform under relevant PRC regulation, such as prescription drugs and foreign currencies. Failure to identify and remove such products and content from our platform may subject us to liability and administrative penalties. Any of these events could have a material and adverse effect on our business, results of operations or financial condition.

        Under our standard form agreements, we require our merchants to indemnify us for any losses we suffer or any costs that we incur due to any products sold by these merchants. However, we may not be able to successfully enforce our contractual rights and may need to initiate costly and lengthy legal proceedings in China to protect our rights.

        In addition to fraudulent transactions with legitimate buyers, merchants on our platform may engage in fictitious transactions with themselves or collaborate with third parties in order to artificially inflate their sales records and search results rankings. Such activity may frustrate other merchants by enabling the perpetrating merchants to be favored over legitimate merchants, and may harm buyers by

S-24

Table of Contents

misleading them to believe that a merchant is more reliable or trustworthy than the merchant actually is. We are also aware that certain merchants and users engage in fictitious transactions on e-commerce platforms to facilitate illegal activities such as online gambling. Fictitious transactions may result in inflated GMV, total orders and other key metrics. Although we have implemented strict measures to detect and penalize merchants who engaged in fictitious transactions on our platform, there can be no assurance that such measures will be effective in preventing all fraudulent transactions or deter illegal activities.

        Moreover, illegal, fraudulent or collusive activities by our employees could also subject us to liability or negative publicity. There were occasions where we found our employees accepting payments from merchants in exchange for preferential treatment on our platform, and we reported such behavior to the relevant government authorities.

        Although we implement a zero-tolerance policy towards these activities and have not been charged with any wrongdoing, there can be no assurance that our controls and policies will prevent all fictitious, fraudulent or illegal activities by merchants, users or our employees or that similar incidents will not occur in the future. Any inquiries, investigations and other governmental actions associated with and negative publicity and user sentiment resulting from similar incidents could divert significant management time and attention, severely diminish consumer confidence in us and the value of our brand, and would materially and adversely affect our business, financial condition and results of operations.

We may be subject to claims under consumer protection laws, including health and safety claims and product liability claims, if property or people are harmed by the products and services sold on our platform. Additionally, new laws and regulations may impose additional requirements and other obligations on our business, which may materially and adversely affect our business, financial conditions and results of operations.

        The PRC government, media outlets and public advocacy groups have been increasingly focused on consumer protection in recent years. The products sold by third-party merchants on our platform may be defectively designed or manufactured, and offerings of defective products on our platform may expose us to liabilities associated with consumer protection laws. Operators of e-commerce platforms are subject to certain provisions of consumer protection laws even where the operator is not the manufacturer or provider of the products or services purchased by the consumer. For example, under applicable consumer protection laws in China, e-commerce platform operators may be held liable for consumer claims relating to damage if they are unable to provide consumers with the true name, address and contact details of merchants. In addition, if we do not take appropriate remedial action against merchants for actions they engage in that we know, or should have known, would infringe upon the rights and interests of consumers, we may be held jointly liable for infringement alongside the merchants. Moreover, applicable consumer protection laws in China provide that platforms will be held liable for failing to meet any undertakings that the platforms make to consumers with regard to products listed on their platforms. Furthermore, we are required to report to the State Administration for Market Regulation, or SAMR, formerly known as the State Administration for Industry and Commerce, or SAIC, or its local branches any violation of applicable laws, regulations or SAMR or SAIC rules by merchants, such as sales of goods without proper license or authorization, and we are required to take appropriate remedial measures, including ceasing to provide services to the relevant merchants. We may also be held jointly liable with merchants who do not possess the proper licenses or authorizations to sell goods or sell goods that do not meet product standards.

        We do not maintain product liability insurance for products transacted on our platform, and our rights of indemnity from the merchants on our platform may not adequately cover us for any liability we may incur. Even unsuccessful claims could result in significant expenditure of funds and diversion of management time and resources, which could materially and adversely affect our business, financial condition and prospects.

        In addition, the PRC government authorities may continue to promulgate new laws, regulations and rules governing the e-commerce industry, tighten enforcement of existing laws, rules and regulations, and impose additional requirements and other obligations on our business including the operation of our e-commerce platform and our market promotion activities. Compliance with these laws, regulations and rules may be costly, and any incompliance or associated inquiries, investigations and other governmental actions may divert significant management time and attention and our financial resources, bring negative publicity, or subject us to liabilities or administrative penalties. For example, in August 2018, the standing committee of the National People's Congress promulgated the E-Commerce Law, which took effect in January 2019. According to the E-Commerce Law, e-commerce platform operators who fail to take necessary actions when they know or should have known that the merchants on their platform infringe others' intellectual property rights or the products or services provided by the merchants do not meet the requirements for product safety, or otherwise infringe upon consumers' legitimate rights, will be held jointly liable with the merchants. Additionally, with respect to the products or services affecting consumers' life and health, the e-commerce platform operators will bear relevant responsibilities if they fail to review the qualifications of merchants or fail to safeguard the interests of the consumers.

        The E-Commerce Law also requires e-commerce platform operators to take necessary actions if merchants on the platform fail to display prominently on their respective platform web page the information contained in their business licenses or administrative permits relating to their operating businesses. According to the E-Commerce Law, all e-commerce operators, including individuals and entities carrying out their business online and e-commerce platform operators and merchants on these platforms, should register with the relevant local branches of SAMR. Individuals selling agricultural products or conducting certain transactions with minimum economic value and low volume are not subject to these registration requirements. In addition, e-commerce platform operators should provide identity information of merchants on their platform to local branches of SAMR and procure the merchants who fail to make such registrations to comply with the relevant registration requirements. We set clear requirements for all merchants on our platform to complete such registrations. As a result of such requirements, we may lose existing merchants who do not conduct or fail to conduct such registrations and we may fail to attract potential merchants who might not be willing to cooperate with us in full compliance with the E-Commerce Law. See "Item 4. Information on the Company—B. Business Overview—Regulation—Regulations Relating to E-Commerce" in our 2019 Annual Report. Such new laws, regulations and rules may result in additional compliance obligations and increased costs or place restrictions upon our current or future operations, and may materially and adversely affect our business, financial condition and results of operations.

        In October 2020, the SAMR issued the Interim Provisions for Regulating Promotional Activities, which will take effect on December 1, 2020. Among other things, these interim provisions are designed to promote consumer protection and prohibit false or misleading commercial information used in promotional activities. As a platform operator, we are required by the interim provisions to design rules and procedures to foster fair and transparent merchandise promotional activities, and assist the authorities in their investigation of violations by platform merchants. Failure to comply with these provisions may subject us to penalties or other administrative actions by regulatory authorities. In early November 2020, the SAMR further published a draft Anti-monopoly Guidelines for the Platform Economy Sector that aims at enhancing anti-monopoly administration of businesses that operate under the platform model and the overall platform economy. These draft guidelines are now open for public comment and are pending finalization and enactment. Due to the uncertainties associated with the evolving legislative activities and varied local implementation practices of anti-monopoly and competition laws and regulations in the PRC, compliance with these laws, regulations, rules, guidelines and implementations may be costly, and any incompliance or associated inquiries, investigations and other governmental actions may divert significant management time and attention and our financial resources, bring negative publicity, subject us to liabilities or administrative penalties, and/or materially and adversely affect our financial conditions, operations and business prospects.

We may face challenges in expanding our product offerings.

        The merchants on our platform carry a wide range of products, including apparel, shoes, bags, mother and childcare products, food and beverage, fresh produce, electronic appliances, furniture and household goods, cosmetics and other personal care items, sports and fitness items and auto accessories. Expansion of product offerings both in categories and items involve new risks and challenges. Our lack of familiarity with these products and lack of relevant buyer data relating to these products may make it more difficult for us to anticipate buyer demand and preferences and to inspect and control quality and ensure proper handling, storage and delivery by our merchants. Our merchants may experience higher return rates on new products, receive more buyer complaints about such products and face costly product liability claims as a result of selling such products, which would harm our brand and reputation as well as our financial performance. We may also be involved in disputes with the merchants in connection with these claims and complaints.

        As we broaden our product offerings, we will need to work with a large number of new merchants efficiently and establish and maintain mutually beneficial relationships with our existing and new merchants. To support our growth and our expansion, we will need to devote management, operating, financial and human resources which may divert our attention from existing businesses, incur upfront costs, and implement a variety of new and upgraded management, operating, financial and human resource systems, procedures and controls. There is no assurance that we will be able to implement all of these systems, procedures and control measures successfully or address the various challenges in expanding our future businesses and operations effectively. In addition, our newly launched initiatives such as livestreaming and Duo Duo Maicai may face risks and uncertainties and may not grow successfully.

Tencent provides services to us in connection with various aspects of our operations. If such services become limited, restricted, curtailed or less effective or more expensive in any way or become unavailable to us for any reason, our business may be materially and adversely affected.

        We collaborate with Tencent, one of our principal shareholders and owner of Weixin and QQ, with respect to various aspects of our business, including our mini-program within Weixin and the entry point to our mini-program in Weixin Pay, which serves as one of our access points to our platform, as well as services such as payment processing, advertising and cloud technology. We have entered into a strategic cooperation framework agreement with Tencent, pursuant to which we and Tencent have agreed to cooperate in a number of areas including payment solutions, cloud services and user engagement, and to explore and pursue additional opportunities for potential cooperation.

        If services provided by Tencent to us become limited, compromised, restricted, curtailed or less effective or become more expensive or unavailable to us for any reason, including the availability of our mini-program within Weixin and the entry point to our mini-program in Weixin Pay, our business may be materially and adversely affected. We may also encounter difficulties in implementing the Strategic Cooperation Framework Agreement, which may divert significant management attention from existing business operations. Failure to maintain our relationship with Tencent could materially and adversely affect our business and results of operations. See "Item 7. Major Shareholders and Related Party Transactions—B. Related Party Transactions" in our 2019 Annual Report.

Impairment of long-lived assets could materially and adversely affect our results of operations and book value.

        We have accumulated long-lived assets as a result of our operations. We review these assets, including intangible assets with finite lives, for impairment annually and whenever events or changes in circumstances arise that will impact the future use of these assets. In the event that the book value of long-lived assets is impaired, such impairment would be charged to earnings in the period when such impairment is determined. Any future impairment of long-lived assets could have a material and

adverse effect on our profitability, results of operations and book value. For more information on our impairment testing, see the consolidated financial statements included elsewhere in this prospectus supplement and incorporated by reference in the accompanying prospectus.

We rely on proper operation and maintenance of our mobile platform and internet infrastructure and telecommunications networks in China. Any malfunction, capacity constraint or operation interruption may have an adverse impact on our business.

        Currently, all of our sales of products are generated online through our Pinduoduo mobile platform. Therefore, the satisfactory performance, reliability and availability of our mobile platform are critical to our success and our ability to attract and retain buyers. Our business depends on the performance and reliability of the internet infrastructure in China. The reliability and availability of our mobile platform depends on telecommunications carriers and other third-party providers for communications and storage capacity, including bandwidth and server storage, among other things. If we are unable to enter into and renew agreements with these providers on acceptable terms, or if any of our existing agreements with such providers are terminated as a result of our breach or otherwise, our ability to provide our services to our buyers could be adversely affected. Access to internet in China is maintained through state-owned telecommunications carriers under administrative control, and we obtain access to end-user networks operated by such telecommunications carriers and internet service providers to give buyers access to our mobile platform. The failure of telecommunications network operators to provide us with the requisite bandwidth could also interfere with the speed and availability of our mobile platform. Service interruptions prevent buyers from accessing our mobile platform and placing orders, and frequent interruptions could frustrate buyers and discourage them from attempting to place orders, which could cause us to lose buyers and harm our operating results. In addition, we have no control over the costs of the services provided by the telecommunications operators. If the prices that we pay for telecommunications and internet services rise significantly, our financial results could be adversely affected.

We may engage in acquisitions, investments or strategic alliances, which could require significant management attention and materially and adversely affect our business and results of operations.

        We may from time to time identify strategic partners to form strategic alliances, invest in or acquire additional assets, technologies or businesses that are complementary to our existing business. These transactions may involve minority investments in other companies, acquisitions of controlling stakes in other companies or acquisitions of selected assets.

        Any strategic alliances, investments or acquisitions and the subsequent integration of the new assets and businesses obtained or developed from such transactions into our own may divert management from their primary responsibilities and subject us to additional liabilities. In addition, the costs of identifying and consummating investments and acquisitions may be significant. We may also incur costs and experience uncertainties in completing necessary registrations and obtaining necessary approvals from relevant government authorities in China and elsewhere in the world. The costs and duration of integrating newly acquired assets and businesses could also materially exceed our expectations. Any such negative developments could have a material adverse effect on our business, financial condition, results of operations and cash flow.

        Our financial results could be adversely affected by our investments or acquisitions. The investments and acquired assets or businesses may not generate anticipated synergies with our business or achieve anticipated financial growth as we would expect. They could result in significant investments and goodwill impairment charges and amortization expenses for other intangible assets, which would adversely affect our financial condition and operating results.

Undetected programming errors or flaws or failure to maintain effective customer service could damage our reputation or even cause direct loss to us which would materially and adversely affect our results of operations.

        Our platform and internal systems rely on software that is highly technical and complex. In addition, our platform and internal systems depend on the ability of such software to store, retrieve, process and manage an immense amount of data and the ability of their operators to operate these complex systems properly. The software on which we rely may contain undetected programming errors or design defects, some of which may only be discovered after the code has been released. Improper operations or other human errors may also occur from time to time as a result of operating such software and complex systems. Programming errors or design defects within the software or human errors in connection with the operation of the software may result in negative experience to buyers using our platform, disruptions to the operations of our merchants, delay in introductions of new features or enhancements, unintended disclosure of confidential information of buyers, merchants and our platform or compromise in our ability to provide effective customer service and enjoyable user engagement or exploitation of loopholes by dishonest buyers or merchants. They could cause damage to our reputation, loss of buyers or merchants, or direct economic loss to us.

Our business generates and processes a large amount of data, and we are required to comply with PRC and other applicable laws relating to privacy and cyber security. The improper use or disclosure of data could have a material and adverse effect on our business and prospects.

        Our business generates and processes a large quantity of data. We face risks inherent in handling and protecting large volume of data. In particular, we face a number of challenges relating to data from transactions and other activities on our platforms, including:

•

protecting the data in and hosted on our system, including against attacks on our system by outside parties or fraudulent behavior or improper use by our employees;



•

addressing concerns related to privacy and sharing, safety, security and other factors; and



•

complying with applicable laws, rules and regulations relating to the collection, use, storage, transfer, disclosure and security of personal information, including any requests from regulatory and government authorities relating to this data.

        The PRC regulatory and enforcement regime with regard to data security and data protection is evolving. We may be required by Chinese governmental authorities to share personal information and data that we collect to comply with PRC laws relating to cybersecurity. See "Item 4. Information on the Company—B. Business Overview—Regulation—Regulations Relating to Internet Information Security and Privacy Protection" in our 2019 Annual Report. The law imposes heightened regulation and additional security and privacy protection obligations on operators of critical information infrastructure. The PRC National Security Law covers various types of national security, including technology security and information security. All the relevant laws and regulations may result in additional expenses to us and any non-compliance and misuse of or failure to secure personal information could have a negative impact on our financial results and may subject us to negative publicity, which could harm our reputation and negatively affect the trading price of our ADSs. There are also uncertainties with respect to how these laws will be implemented in practice. PRC regulators, including the MIIT and the Cyberspace Administration of China, or the Cyberspace Administration, have been increasingly focused on regulation in the areas of data security and data protection. On November 28, 2019, the Secretary Bureau of the Cyberspace Administration of China, the General Office of the MIIT, the General Office of the Ministry of Public Security and the General Office of the State Administration for Market Regulation promulgated the Identification Method of Illegal Collection and Use of Personal Information Through App, which provides guidance for regulatory authorities to identify the illegal collection and use of personal information through mobile apps and for mobile app operators to

conduct self-examination and self-correction. In July 2020, the Standing Committee of the National People's Congress published for public comment a draft Data Security Law, which provided that at the national level, varying levels of data protective measures will be applied based on the level of importance of the data and a centralized mechanism for risk assessment, risk monitoring, early potential data security risk warning and emergency response will be established. The draft Data Security Law also set forth the data security protection obligations for entities and individuals handling personal data, including that no entity or individual may acquire such data by stealing or other illegal means, and the collection and use of such data should not exceed the necessary limits. In addition, the draft Anti-monopoly Guidelines for the Platform Economy Sector published by the SAMR for public comment in November 2020, if implemented under its current form, would also prohibit compulsory user information collection by online platforms operators. Compliance with these laws, regulations and rules may be costly, and any incompliance or associated inquiries, investigations and other governmental actions may divert significant management time and attention and our financial resources, bring negative publicity, or subject us to liabilities or administrative penalties and/or materially and adversely affect our financial conditions, operations and business prospects.

        The European Union General Data Protection Regulation ("GDPR"), which came into effect on May 25, 2018, includes operational requirements for companies that receive or process personal data of residents of the European Economic Area. The GDPR establishes new requirements applicable to the processing of personal data, affords new data protection rights to individuals and imposes penalties for serious data breaches. Individuals also have a right to compensation under the GDPR for financial or non-financial losses. Although we do not conduct any business in the European Economic Area, in the event that residents of the European Economic Area access our website or our mobile platform and input protected information, we may become subject to provisions of the GDPR.

        In addition, regulatory authorities around the world have recently adopted or are considering a number of legislative and regulatory proposals concerning data protection. These legislative and regulatory proposals, if adopted, and the uncertain interpretations and application thereof could, in addition to the possibility of fines, result in an order requiring that we change our data practices and policies, which could have an adverse effect on our business and results of operations.

        Furthermore, we expect that data security and data protection compliance will receive greater attention and focus from regulators, as well as attract continued or greater public scrutiny and attention going forward, which could increase our compliance costs and subject us to heightened risks and challenges associated with data security and protection. If we are unable to manage these risks, we could become subject to penalties, including fines, suspension of business and revocation of required licenses, and our reputation and results of operations could be materially and adversely affected.

Failure to protect confidential information of buyers, merchants and our network against security breaches could damage our reputation and brand and substantially harm our business and results of operations.

        A significant challenge to the e-commerce industry is the secure storage of confidential information and its secure transmission over public networks. A majority of the orders and the payments for products offered on our platform are made through our mobile app. In addition, all online payments for products sold on our platform are settled through third-party online payment services. Maintaining complete security on our platform and systems for the storage and transmission of confidential or private information, such as buyers' personal information, payment-related information and transaction information, is essential to maintain consumer confidence in our platform and systems.

        We have adopted strict security policies and measures, including encryption technology, to protect our proprietary data and buyer information. However, advances in technology, the expertise of hackers, new discoveries in the field of cryptography or other events or developments could result in a compromise or breach of the technology that we use to protect confidential information. We may not

S-30

be able to prevent third parties, especially hackers or other individuals or entities engaging in similar activities through viruses, Trojan horses, malicious software, break-ins, phishing attacks, third-party manipulation or security breaches, from illegally obtaining such confidential or private information we hold with respect to buyers and merchants on our platform. Such individuals or entities obtaining confidential or private information may further engage in various other illegal activities using such information. The methods used by hackers and others engaging in illegal online activities are increasingly more sophisticated and constantly evolving. Significant capital, managerial and other resources, including costs incurred to deploy additional personnel and develop network protection technologies, train employees, and engage third-party experts and consultants, may be required to ensure and enhance information security or to address the issues caused by such security failure.

        In addition, we have limited control or influence over the security policies or measures adopted by third-party providers of online payment services through which some of our buyers may choose to make payment for purchases. Any negative publicity on our platform's safety or privacy protection mechanisms and policies, and any claims asserted against us or fines imposed upon us as a result of actual or perceived failures, could have a material and adverse effect on our public image, reputation, financial condition and results of operations. Any compromise of our information security or the information security measures of our contracted third-party online payment service providers could have a material and adverse effect on our reputation, business, prospects, financial condition and results of operations.

We currently rely on commercial banks and third-party online payment service providers for payment processing and escrow services on our platform. If these payment services are restricted or curtailed in any way, are offered to us on less favorable terms, or become unavailable to us or our buyers for any reason, our business may be materially and adversely affected.

        All online payments for products sold on our platform are settled through third-party online payment service providers. Our business depends on the billing, payment and escrow systems of these payment service providers to maintain accurate records of payments of sales proceeds by buyers and collect such payments. If the quality, utility, convenience or attractiveness of these payment processing and escrow services declines, or we have to change the pattern of using these payment services for any reason, the attractiveness of our platform could be materially and adversely affected.

        Business involving online payment services is subject to a number of risks that could materially and adversely affect third-party online payment service providers' ability to provide payment processing and escrow services to us, including:

•

dissatisfaction with these online payment services or decreased use of their services by buyers and merchants;



•

increasing competition, including from other established Chinese internet companies, payment service providers and companies engaged in other financial technology services;



•

changes to rules or practices applicable to payment systems that link to third-party online payment service providers;



•

breach of buyers' personal information and concerns over the use and security of information collected from buyers;



•

service outages, system failures or failures to effectively scale the system to handle large and growing transaction volumes;



•

increasing costs to third-party online payment service providers, including fees charged by banks to process transactions through online payment channels, which would also increase our costs of revenues; and

S-31

•

failure to manage funds accurately or loss of funds, whether due to employee fraud, security breaches, technical errors or otherwise.

        Certain commercial banks in China impose limits on the amounts that may be transferred by automated payment from buyers' bank accounts to their linked accounts with third-party online payment services. We cannot predict whether these and any additional restrictions that could be put in place would have a material adverse effect on our platform.

        The commercial banks and third-party online payment service providers that we work with are subject to the supervision of the People's Bank of China, or the PBOC. The PBOC may publish rules, guidelines and interpretations from time to time regulating the operation of financial institutions and payment service providers that may in turn affect the pattern of services provided by such entities for us. For example, in November 2017, the PBOC published a notice, or the PBOC Notice, on the investigation and administration of illegal offering of settlement services by financial institutions and third-party payment service providers to unlicensed entities. The PBOC Notice intended to prevent unlicensed entities from using licensed payment service providers as a conduit for conducting the unlicensed payment settlement services, so as to safeguard the fund security and information security. We believe that our pattern of receiving settlement services from third-party online payment service providers is not in violation of the PBOC Notice because the relevant commercial bank opens an internal special account to receive payment from the buyers and we will submit to the bank materials verifying the truthfulness of the relevant transactions and the bank will also verify other information if it deems necessary before it distributes the payment to merchants and us. However, we cannot assure you that the PBOC or other governmental authorities will hold the same view with ours. If required by the PBOC or new legislation, our cooperative payment service providers will have to suspend their services or explore new models to offer their services to us, we may not be able to claim our ownership and exclusive control of the payments from the buyers in the bank accounts opened with the relevant commercial banks, and we may incur additional expenses or invest considerable resources in complying with the requirements. If the PBOC or other governmental authorities deem our cooperation with payment service providers to be violative of law, we may also have to suspend or terminate our cooperation with these payment service providers or explore new models for using their services, and our income derived from the accrued interests in the relevant bank accounts may be confiscated, and we may be subject to a fine of one to five times of such income.

        We cannot assure you that we will be successful in entering and maintaining amicable relationships with these commercial banks and online payment service providers. Identifying, negotiating and maintaining relationships with these providers require significant time and resources. Our current agreements with these service providers also do not prohibit them from working with our competitors. They could choose to terminate their relationships with us or propose terms that we cannot accept. Moreover, we cannot guarantee that the terms we negotiated with these payment service providers, including the payment processing fee rates, will remain as favorable. If the terms with these payment service providers become less favorable to us, such as the increase of payment processing fee rate, we may have to raise the transaction services fees for certain of our merchants, which may cause us to lose merchants, or absorb the additional costs by ourselves, both of which may materially and adversely affect our business, financial condition and results of operations. Furthermore, these service providers may not perform as expected under our agreements with them, and we may have disagreements or disputes with such payment service providers, any of which could adversely affect our brand and reputation as well as our business operations.

We do not control Shanghai Fufeitong and the majority of its equity interests is indirectly controlled by our executive officers. If any conflict arises between us and Shanghai Fufeitong and cannot be resolved in our favor, our business, financial condition, results of operations and prospects may be materially and adversely affected.

        In April 2020, Shanghai Xunmeng, a subsidiary of our VIE, entered into a business cooperation agreement with Shanghai Fufeitong Information Service Co., Ltd., or Shanghai Fufeitong, pursuant to which both parties agreed to conduct comprehensive business cooperation in payment services, technical resources and other related professional areas. As Shanghai Fufeitong is a company which Messrs. Lei Chen and Zhenwei Zheng, our executive officers, indirectly hold 50.01% of the equity interests in, the transaction constitutes our related party transaction. See "Item 7. Major Shareholders and Related Party Transactions—B. Related Party Transactions—Loan to Ningbo Hexin and Business Cooperation Agreement with Shanghai Fufeitong" in our 2019 Annual Report for more details of the transactions.

        As Shanghai Fufeitong, which we do not have control over, also provides payment services to other parties from time to time, we cannot assure you that Shanghai Fufeitong's transactions with other parties or its pursuit of opportunities and development would not conflict with our interests. There can be no assurance that Messrs. Lei Chen and Zhenwei Zheng, in light of their control over Shanghai Fufeitong, would act in favor of our interests if any conflict arises between us and Shanghai Fufeitong. If the conflict cannot be resolved in our favor, our business, financial condition, results of operations and prospects may be materially and adversely affected.

        Moreover, due to our cooperation with Shanghai Fufeitong, any event that negatively affects Shanghai Fufeitong may also negatively affect the perception of our customers, merchants, regulators and other third parties on us and may further adversely and materially affect our reputation, business, results of operations and prospects.

Any lack of additional requisite approvals, licenses or permits or failure to comply with any requirements of PRC laws, regulations and policies may materially and adversely affect our daily operations and hinder our growth.

        Our business is subject to governmental supervision and regulation by the relevant PRC governmental authorities, including the Ministry of Commerce, or MOFCOM, the Ministry of Industry and Information Technology, or the MIIT, the National Radio and Television Administration, or the NRTA, and other governmental authorities in charge of the relevant categories of products sold by us. Together, these government authorities promulgate and enforce regulations that cover many aspects of the operation of online retailing and related business, including entry into this industry, the scope of permissible business activities, licenses and permits for various business activities, and foreign investment. We are required to hold a number of licenses and permits in connection with our business operation, including the ICP license and approvals for the establishment of foreign-invested enterprises engaging in the sale of goods over the internet. We have in the past held and currently hold all material licenses and permits described above and may apply for certain additional licenses with the government authorities in the future to maintain compliance especially when we take on new business activities. See "Item 4. Information on the Company—B. Business Overview—Regulation—Regulations Relating to Foreign Investment" and "Item 4. Information on the Company—B. Business Overview—Regulation—Licenses, Permits and Filings" in our 2019 Annual Report.

        As of the date of this prospectus supplement, we have not been subject to penalties or other disciplinary action from the relevant governmental authorities regarding conducting our business without proper approvals, licenses and permits. However, we cannot assure you that we will not receive such notice of warning or be subject to penalties or other disciplinary actions in the future. As the online retail industry is still evolving in China, new laws and regulations may be adopted from time to

S-33

Table of Contents

time to require additional licenses and permits other than those we currently have, and to address new issues that arise from time to time. As a result, substantial uncertainties exist regarding the interpretation and implementation of current and any future PRC laws and regulations applicable to online retail and related businesses. If the PRC government considers us operating without proper approvals, licenses, filings, registrations or permits or promulgates new laws and regulations that require additional approvals, filings, registrations or licenses or impose additional restrictions on the operation of any part of our business, it has the power, among other things, to levy fines, confiscate our income, revoke our business licenses, and require us to discontinue our relevant business or impose restrictions on the affected portion of our business. Any of these and other regulatory actions by the PRC governmental authorities, including issuance of official notices, change of policies, promulgation of regulations and imposition of sanctions, may adversely affect our business and have a material and adverse effect on our results of operations. In addition, if we were to use new or additional domain names to conduct our business, we would have to apply for the same set of government authorizations or amend the current ones. There is no assurance that we will be able to complete such procedures timely.

        PRC laws and regulations may also require e-commerce platform operators to take measures to protect consumer rights. Failure to do so may subject the e-commerce platform operators to rectification requirements and penalties. Although we endeavor to comply with the relevant laws and regulations, there is no assurance that we can timely react to the evolving requirements. If the competent governmental authorities deem that we fail to meet such requirements, we may receive warnings, be ordered to make rectifications, or subject to other administrative sanctions and/or penalties that may have a material adverse effect on our reputation, business, financial condition and results of operations. For example, in January 2019, we were ordered by the local regulatory authority to pay a fine of RMB30,000 for failure to comply with the legal requirements with respect to the display and update of individual merchants' identities and full disclosure of platform policies.

        We are required by PRC laws and regulations to comply with labor laws and regulations and pay overtime compensation and various government statutory employee benefit plans, including medical insurance, maternity insurance, workplace injury insurance, unemployment insurance and pension benefits through a PRC government-mandated multi-employer defined contribution plan. The relevant government agencies may examine whether an employer has made adequate payments of the requisite statutory employee benefits, and those employers who fail to make adequate payments may be subject to late payment fees, fines and/or other penalties. If the relevant PRC authorities determine that we shall make supplemental contributions, that we are not in compliance with labor laws and regulations, or that we are subject to fines or other legal sanctions, such as order of timely rectification, our business, financial condition and results of operations may be adversely affected.

        Pursuant to the Individual Income Tax Law of the PRC, as amended on August 31, 2018, which became effective on January 1, 2019, an individual's taxable income shall be an amount equal to such individual's total annual income less a general deductible of RMB60,000 and various special deductibles permitted under relevant laws. Determination and calculation of such special deductibles in accordance with relevant laws may result in an increase of our operating costs and expenses. However, as these laws and implementing rules were only recently promulgated and their interpretations have not been entirely settled yet, our determination and calculation of the special deductibles based on our understanding may be different from how the tax authorities or our employees would do. These differences may result in inquiries or reassessment by the tax authorities, as well as disputes with our employees.

We may increasingly become a target for public scrutiny, including complaints to regulatory agencies, negative media coverage, and public dissemination of malicious reports or accusations about our business, all of which could severely damage our reputation and materially and adversely affect our business and prospects.

        We process an extremely large number of transactions on a daily basis on our platform, and the high volume of transactions taking place on our platform as well as publicity about our business create the possibility of heightened attention from the public, regulators and the media. Heightened regulatory and public concerns over consumer protection and consumer safety issues may subject us to additional legal and social responsibilities and increased scrutiny and negative publicity over these issues, due to the large number of transactions that take place on our platform and the increasing scope of our overall business operations. In addition, changes in our services or policies have resulted and could result in objections by members of the public, the traditional, new and social media, social network operators, merchants on our platform or others. From time to time, these objections or allegations, regardless of their veracity, may result in consumer dissatisfaction, public protests or negative publicity, which could result in government inquiry or substantial harm to our brand, reputation and operations.

        Moreover, as our business expands and grows, both organically and through acquisitions of and investments in other businesses, domestically and internationally, we may be exposed to heightened public scrutiny in jurisdictions where we already operate as well as in new jurisdictions where we may operate. There is no assurance that we would not become a target for regulatory or public scrutiny in the future or that scrutiny and public exposure would not severely damage our reputation as well as our business and prospects.

        Furthermore, our brand name and our business may be harmed by aggressive marketing and communication strategies by third parties. We may be subject to government or regulatory investigation or third-party claims as a result and we may be required to spend significant time and incur substantial costs to react to and address these consequences. There is no assurance that we will be able to effectively refute each of the allegations within a reasonable period of time, or at all. Additionally, public allegations, directly or indirectly, against us or the merchants on our platform, may be posted on internet forums, blogs or websites by anyone on an anonymous basis. The availability of information on social media platforms is virtually immediate, as is its impact. Social media platforms may not necessarily filter or check the accuracy of information before publishing them and we are often afforded little or no time to respond. As a result, our reputation may be materially and adversely affected and our ability to attract and retain customers and maintain our market share and profitability may suffer.

Our online marketing services constitute internet advertisement, which subjects us to laws, rules and regulations applicable to advertising.

        We derive a significant amount of our revenues from online marketing services and other related services. In July 2016, SAIC promulgated the Interim Administrative Measures on Internet Advertising, or the Internet Advertising Measures, effective September 2016, pursuant to which internet advertisements are defined as any commercial advertising that directly or indirectly promotes goods or services through internet media in any form including paid-for search results. See "Item 4. Information on the Company—B. Business Overview—Regulation—Regulations Relating to Internet Advertising Business" in our 2019 Annual Report. Under the Internet Advertising Measures, our online marketing services and other related services constitute internet advertisement.

        PRC advertising laws, rules and regulations require advertisers, advertising operators and advertising distributors to ensure that the content of the advertisements they prepare or distribute is fair and accurate and is in full compliance with applicable law. In the nine months period ended September 30, 2020, 89.3% of our revenues were derived from online marketing services and others. Violation of these laws, rules or regulations may result in penalties, including fines, confiscation of

S-35

Table of Contents

advertising fees and orders to cease dissemination of the advertisements. In circumstances involving serious violations, the PRC government may suspend or revoke a violator's business license or license for operating advertising business. In addition, the Internet Advertising Measures require paid-for search results to be distinguished from natural search results so that consumers will not be misled as to the nature of these search results. As such, we are obligated to distinguish from others the merchants who purchase online marketing and related services or the relevant listings by these merchants. Complying with these requirements and any penalties or fines for any failure to comply may significantly reduce the attractiveness of our platform and increase our costs and could have a material adverse effect on our business, financial condition and results of operations.

        In addition, for advertising content related to specific types of products and services, advertisers, advertising operators and advertising distributors must confirm that the advertisers have obtained requisite government approvals, including the advertiser's operating qualifications, proof of quality inspection of the advertised products, and, with respect to certain industries, government approval of the content of the advertisement and filing with the local authorities. Pursuant to the Internet Advertising Measures, we are required to take steps to monitor the content of advertisements displayed on our platforms. This requires considerable resources and time, and could significantly affect the operation of our business, while at the same time also exposing us to increased liability under the relevant laws, rules and regulations. The costs associated with complying with these laws, rules and regulations, including any penalties or fines for our failure to so comply if required, could have a material adverse effect on our business, financial condition and results of operations. Any further change in the classification of our online marketing and other related services by the PRC government may also significantly disrupt our operations and materially and adversely affect our business and prospects.

We may be subject to intellectual property infringement claims, which may be expensive to defend and may disrupt our business and operations.

        We cannot be certain that our operations or any aspects of our business do not or will not infringe upon or otherwise violate patents, copyrights or other intellectual property rights held by third parties. We have been, and from time to time in the future may be, subject to legal proceedings and claims relating to the intellectual property rights of others. In addition, there may be other third-party intellectual property that is infringed by products offered by our merchants and our services or other aspects of our business. There could also be existing patents of which we are not aware that our products may inadvertently infringe. We cannot assure you that holders of patents purportedly relating to some aspect of our technology platform or business, if any such holders exist, would not seek to enforce such patents against us in China, the United States or any other jurisdictions. Further, the application and interpretation of China's patent laws and the procedures and standards for granting patents in China are still evolving and are uncertain, and we cannot assure you that PRC courts or regulatory authorities would agree with our analysis. If we are found to have violated the intellectual property rights of others, we may be subject to liability for our infringement activities or may be prohibited from using such intellectual property, and we may incur licensing fees or be forced to develop alternatives of our own. In addition, we may incur significant expenses, and may be forced to divert management's time and other resources from our business and operations to defend against these infringement claims, regardless of their merits. Successful infringement or licensing claims made against us may result in significant monetary liabilities and may materially disrupt our business and operations by restricting or prohibiting our use of the intellectual property in question. Finally, we use open source software in connection with our products and services. Companies that incorporate open source software into their products and services have, from time to time, faced claims challenging the ownership of open source software and compliance with open source license terms. As a result, we could be subject to suits by parties claiming ownership of what we believe to be open source software or noncompliance with open source licensing terms. Some open source software licenses require users

S-36

Table of Contents

who distribute open source software as part of their software to publicly disclose all or part of the source code to such software and make available any derivative works of the open source code on unfavorable terms or at no cost. Any requirement to disclose our source code or pay damages for breach of contract could be harmful to our business, results of operations and financial condition.

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

        We regard our trademarks, copyrights, patents, domain names, know-how, proprietary technologies, and similar intellectual property as critical to our success, and we rely on a combination of intellectual property laws and contractual arrangements, including confidentiality, invention assignment and non-compete agreements with our employees and others, to protect our proprietary rights. We are aware of certain copycat websites that attempt to cause confusion or diversion of traffic from us at the moment, against which we are considering initiating lawsuits, and we may continue to become an attractive target to such attacks in the future because of our brand recognition in the online retail industry in China. Despite these measures, any of our intellectual property rights could be challenged, invalidated, circumvented or misappropriated, or such intellectual property may not be sufficient to provide us with competitive advantages. In addition, there can be no assurance that (i) our application for registration of trademarks, patents, and other intellectual property rights will be approved, (ii) any intellectual property rights will be adequately protected, or (iii) such intellectual property rights will not be challenged by third parties or found by a judicial authority to be invalid or unenforceable. Further, because of the rapid pace of technological change in our industry, parts of our business rely on technologies developed or licensed by third parties, and we may not be able to obtain or continue to obtain licenses and technologies from these third parties at all or on reasonable terms.

        Confidentiality, invention assignment and non-compete agreements may be breached by counterparties, and there may not be adequate remedies available to us for any such breach. Accordingly, we may not be able to effectively protect our intellectual property rights or to enforce our contractual rights. Policing any unauthorized use of our intellectual property is difficult and costly and the steps we take may be inadequate to prevent the infringement or misappropriation of our intellectual property. In the event that we resort to litigation to enforce our intellectual property rights, such litigation could result in substantial costs and a diversion of our management and financial resources, and could put our intellectual property at risk of being invalidated or narrowed in scope. We can provide no assurance that we will prevail in such litigation, and even if we do prevail, we may not obtain a meaningful recovery. In addition, our trade secrets may be leaked or otherwise become available to, or be independently discovered by, our competitors. Any failure in maintaining, protecting or enforcing our intellectual property rights could have a material adverse effect on our business, financial condition and results of operations.

Tightening of tax compliance efforts that affect merchants on our platform could materially and adversely affect our business, financial condition and results of operations.

        The e-commerce industry in China is still developing, and the PRC government may require e-commerce platform operators, such as our company, to assist in the collection of taxes with respect to income generated by merchants from transactions conducted on our platforms. Merchants operating businesses on our platform may be deficient in their tax registration. PRC tax authorities may enforce registration requirements that target these merchants on our platforms and may request our assistance in these efforts. As a result, these merchants may be subject to more stringent tax compliance requirements and liabilities and their business on our platforms could suffer or they could decide to terminate their relationship with us, which could in turn negatively affect us. According to the E-Commerce Law, the e-commerce platform operators shall submit the identity information and the information related to tax payment of the merchants on the platform to the tax authorities. We may

S-37

---

Table of Contents

also be requested by tax authorities to assist in the enforcement of tax regulations, such as disclosure of transaction records and bank account information of the merchants, and withholding against our merchants. If that occurs, we may lose existing merchants and potential merchants might not be willing to operate their business on our platforms. We may be subject to liabilities if we fail to cooperate with the relevant PRC tax authorities to assist in the enforcement as requested. Stricter tax enforcement by the PRC tax authorities may also reduce the activities by merchants on our platforms. Any of these results could have a material adverse effect on our business, financial condition and results of operations.

Our business may be subject to seasonal sales fluctuations which could result in volatility or have an adverse effect on the market price of our ADSs.

        We experience seasonality in our business, reflecting a combination of seasonal fluctuations in internet usage and traditional retail seasonality patterns. For example, we generally experience less user traffic and purchase orders during the Chinese New Year holiday season in the first quarter of each year. Furthermore, online sales in China are significantly higher in the fourth quarter of each calendar year than in the preceding three quarters. Due to the foregoing factors, our financial condition and results of operations for future quarters may continue to fluctuate and our historical quarterly results may not be comparable to future quarters. As a result, the trading price of our ADSs may fluctuate from time to time due to seasonality.

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 2015 (the "2015 Plan") and a share incentive plan in 2018 (the "2018 Plan") for the purpose of granting share-based compensation awards to employees, directors and consultants to incentivize their performance and align their interests with ours. Under each of the share incentive plans, we are authorized to grant options and other types of awards. The maximum aggregate number of ordinary shares which may be issued pursuant to all awards under the 2015 Plan is 581,972,860 Class A ordinary shares, subject to adjustment and amendment, and the maximum aggregate number of shares which may be issued pursuant to all awards under the 2018 Plan was initially 363,130,400 Class A ordinary shares, plus an annual increase on the first day of each fiscal year of our company during the term of the 2018 Plan commencing with the fiscal year beginning January 1, 2019, by an amount equal to the lessor of (i) 1.0% of the total number of shares issued and outstanding on the last day of the immediately preceding fiscal year, and (ii) such number of shares as may be determined by our board of directors. See "Item 4. Information on the Company—B. Compensation" in our 2019 Annual Report for further details. We recognized substantial share-based compensation expenses in our consolidated financial statements in connection with these grants, and may continue to incur such expenses in the future.

        We believe the granting of share-based compensation is of significant importance to our ability to attract and retain key personnel and employees, and we will continue to grant share-based compensation to employees in the future. As a result, our expenses associated with share-based compensation may increase, which may have an adverse effect on our results of operations. We may re-evaluate the vesting schedules, lock-up period, exercise price or other key terms applicable to the grants under our currently effective share incentive plans from time to time. If we choose to do so, our expenses associated with share-based compensation may increase, which may have an adverse effect on our results of operations.

If we fail to implement and maintain an effective system of internal control over financial reporting, our ability to accurately and timely report our financial results or prevent fraud may be adversely affected, and investor confidence and the market price of our ADSs may be adversely impacted.

        We are subject to the reporting requirements of the Exchange Act of 1934, or Exchange Act, the Sarbanes-Oxley Act of 2002, or Sarbanes-Oxley Act, and the rules and regulations of the Nasdaq Global Select Market. The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal control over financial reporting. Commencing with our fiscal year ending December 31, 2019, we must perform system and process evaluation and testing of our internal control over financial reporting to allow management to report on the effectiveness of our internal control over financial reporting in our Form 20-F filing for that year, as required by Section 404 of the Sarbanes-Oxley Act. In addition, as we have ceased 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 beginning with our annual report for the fiscal year ending December 31, 2019. Our management has concluded that our internal control over financial reporting was effective as of December 31, 2019. See "Item 15. Controls and Procedures" in our 2019 Annual Report. If we fail to implement and maintain an effective system of internal control, we will not be able to conclude and our independent registered public accounting firm will not be able to report that we have effective internal control over financial reporting in accordance with the Sarbanes-Oxley Act in our future annual report on Form 20-F covering the fiscal year in which this failure occurs. Effective internal control over financial reporting is necessary for us to produce reliable financial reports. Any failure to maintain effective internal control over financial reporting could prevent us from identifying fraud and result in the loss of investor confidence in the reliability of our financial statements, which in turn could have a material and adverse effect on the trading price of our ADSs. Furthermore, we may need to incur additional costs and use additional management and other resources as our business and operations further expand or in an effort to remediate any significant control deficiencies that may be identified in the future.

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

        In September 2019, we issued US$1 billion in aggregate principal amount of convertible senior notes due 2024, which included the exercise in full by the initial purchasers in that offering of their option to purchase up to an additional US$125 million in aggregate principal amount of the notes (the "2024 Notes"). The 2024 Notes do not bear regular interest, and will mature on October 1, 2024. We may not have sufficient funds to fulfill our payment obligations under the 2024 Notes and the convertible notes offered in the concurrent Convertible Notes Offering, including to repay the convertible notes and/or the 2024 Notes upon maturity, to settle conversions of the convertible notes and/or the 2024 Notes in cash, to repurchase the convertible notes and/or the 2024 Notes upon a tax redemption or an optional redemption thereof or, at the holders' election, upon a fundamental change (as defined in the terms of the convertible notes and the 2024 Notes, respectively) or on the specified dates set forth in the terms of the convertible notes and/or the 2024 Notes.

        We derive most of our revenues from, and hold most of our assets through, our subsidiaries. As a result, we may rely in part upon distributions and advances from our subsidiaries in order to help us meet our payment obligations under the convertible notes, the 2024 Notes and our other obligations. Our subsidiaries are distinct legal entities and do not have any obligation, legal or otherwise, to provide us with distributions or advances. We may face tax or other adverse consequences, or legal limitations, on our ability to obtain funds from these entities. In addition, our ability to obtain external financing in the future is subject to a variety of uncertainties, including:

•

our financial condition, results of operations and cash flows;

S-39

Table of Contents

•

general market conditions for financing activities by internet companies; and



•

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

        If we are unable to obtain funding in a timely manner or on commercially acceptable terms, we may not be able to meet our payment obligations under the convertible notes and/or the 2024 Notes, which in turn may constitute a default under the existing and/or future agreements governing our indebtedness.

Changes in U.S. and international trade policies, particularly with regard to China, may adversely impact our business and operating results.

        The U.S. government has recently proposed, among other actions, imposing new or higher tariffs on specified products imported from China to penalize China for what it characterizes as unfair trade practices and China has responded by proposing new or higher tariffs on specified products imported from the United States. For example, in 2018, the United States announced three finalized tariffs that applied exclusively to products imported from China, totaling approximately US$250 billion, and in May 2019 the United States increased from 10% to 25% the rate of certain tariffs previously levied on Chinese products. Trade tension between China and the United States may intensify, and the United States may adopt even more drastic measures in the future. Although cross-border business may not be an area of our focus, if we plan to sell our products internationally in the future, any unfavorable government policies on international trade, such as capital controls or tariffs, may affect the demand for our products and services, impact the competitive position of our products or prevent us from being able to sell products in certain countries. If any new tariffs, legislation and/or regulations are implemented, or if existing trade agreements are renegotiated such changes could have an adverse effect on our business, financial condition, results of operations. In addition, future actions or escalations by either the United States or China that affect trade relations may cause global economic turmoil and potentially have a negative impact on our business.

        In addition, recent economic and trade sanctions threatened and/or imposed by the U.S. government on a number of China-based technology companies have raised concerns as to whether, in the future, there may be additional regulatory challenges or enhanced restrictions involving other China-based technology companies in areas such as data security, information technology or other business activities. For instance, in May 2019, the U.S. government announced an order effectively barring American firms from selling components and software to a Chinese company and its affiliates. This restriction, and similar or more expansive restrictions that may be imposed by the U.S. or other jurisdictions in the future, may materially and adversely affect our ability to acquire technologies, systems or devices that may be important to our technology infrastructure, service offerings and business operations.

We do not have any business insurance coverage.

        The insurance industry in China is still at an early stage of development, and insurance companies in China currently offer limited business-related insurance products. We do not have any business liability or disruption insurance to cover our operations. We have determined that the costs of insuring for these risks and the difficulties associated with acquiring such insurance on commercially reasonable terms make it impractical for us to have such insurance. Any uninsured risks may result in substantial costs and the diversion of resources, which could adversely affect our results of operations and financial condition.

A severe or prolonged downturn in the global economy could materially and adversely affect our business and financial condition.

        COVID-19 had a negative impact on the Chinese and the global economy in the first half of 2020. Whether this will lead to a prolonged downturn in the economy is still unknown. Even before the outbreak of COVID-19, the global macroeconomic environment was facing numerous challenges. There was considerable uncertainty over the long-term effects of the expansionary monetary and fiscal policies which had been adopted by the central banks and financial authorities of some of the world's leading economies, including the United States and China, even before 2020. Unrest, terrorist threats and the potential for war in the Middle East and elsewhere may increase market volatility across the globe. There have also been concerns about the relationship between China and other countries, including the surrounding Asian countries, which may potentially have economic effects. In particular, there is significant uncertainty about the future relationship between the United States and China with respect to trade policies, treaties, government regulations and tariffs. Any severe or prolonged slowdown in the global economy may materially and adversely affect our business, results of operations and financial condition.

We and certain of our directors and officers have been named as defendants in several lawsuits, which could have a material adverse impact on our business, financial condition, results of operation, cash flows and reputation.

        Between August and December 2018, several putative shareholder class action lawsuits have been filed against us and certain of our directors and officers. See "Item 8. Financial Information—A. Consolidated Statements and Other Financial Information—Legal Proceedings" in our 2019 Annual Report for more details. We are currently unable to estimate the potential loss, if any, associated with the resolution of the outstanding lawsuit, if it proceeds. We may continue to be a target for lawsuits in the future, including putative class action lawsuits brought by shareholders and lawsuits arising from contractual disputes in the ordinary course of our business. There can be no assurance that we will be able to prevail in our defense or reverse any unfavorable judgment on appeal, and we may decide to settle lawsuits on unfavorable terms. Any adverse outcome of these cases, including any plaintiffs' appeal of the judgment in these cases, could result in payments of substantial monetary damages or fines, or changes to our business practices, and thus have a material adverse effect on our business, financial condition, results of operation, cash flows and reputation. In addition, all or part of the defense costs, or any liabilities that may arise from these matters may not be covered by any insurance. The litigation process may utilize a significant portion of our cash resources and divert management's attention from the day-to-day operations of our company, all of which could harm our business. We may also be subject to claims for indemnification related to these matters, and we cannot predict the impact that indemnification claims may have on our business or financial results.

We are a "controlled company" within the meaning of the Nasdaq Stock Market Rules and, as a result, may rely on exemptions from certain corporate governance requirements that provide protection to shareholders of other companies.

        We are a "controlled company" as defined under the Nasdaq Stock Market Rules because our founder and chairman of the board of directors, Mr. Zheng Huang, owns more than 50% of our total voting power. For so long as we remain a controlled company under that definition, we are permitted to elect to rely, and may rely, on certain exemptions from corporate governance rules, including an exemption from the rule that a majority of our board of directors must be independent directors or that we have to establish a nominating committee and a compensation committee composed entirely of independent directors. As a result, you will not have the same protection afforded to shareholders of companies that are subject to these corporate governance requirements. We currently do not plan to rely on these exemptions.

Risks Related to Our Corporate Structure

If the PRC government finds that the agreements that establish the structure for operating some of our operations in China do not comply with PRC regulations relating to the relevant industries, or if these regulations or the interpretation of existing regulations change in the future, we could be subject to severe penalties or be forced to relinquish our interests in those operations.

        Foreign ownership of certain parts of our businesses including value-added telecommunications services ("VATS") is subject to restrictions under current PRC laws and regulations. For example, foreign investors are not allowed to own more than 50% of the equity interests in a value-added telecommunications service provider (excluding e-commerce) and any such foreign investor must have experience in providing value-added telecommunications services overseas and maintain a good track record.

        We are a Cayman Islands company and our PRC subsidiaries, namely our WFOEs, are considered foreign-invested enterprises. Accordingly, our WFOEs are not eligible to provide value-added telecommunications services. As a result, we currently conduct our e-commerce business activities through Shanghai Xunmeng, a subsidiary of our VIE, which holds a VATS License for (i) online data processing and transaction processing business (operating e-commerce), (ii) internet content-related services, (iii) domestic call center business, and (iv) information services. Shanghai Xunmeng is wholly owned by our VIE, namely Hangzhou Aimi, which has obtained and is currently renewing a VATS License covering online data processing and transaction processing business (operating commerce, excluding internet finance and e-hailing services) and internet content-related services (excluding information search and inquiry services and real-time interactive information services). We entered into a series of contractual arrangements with Hangzhou Aimi and its shareholders, which enable us to (i) exercise effective control over our VIE, (ii) receive substantially all of the economic benefits of our VIE, and (iii) have an exclusive option to purchase all or part of the equity interests and assets in our VIE when and to the extent permitted by PRC law. As a result of these contractual arrangements, we have control over and are the primary beneficiary of our VIE and hence consolidate its financial results and its subsidiary into our consolidated financial statements under U.S. GAAP. See "Item 4. Information on the Company—C. Organizational Structure" in our 2019 Annual Report for further details.

        In the opinion of our PRC legal counsel, (i) the ownership structures of our VIE in China and Hangzhou Weimi are not in violation of applicable PRC laws and regulations currently in effect; and (ii) the contractual arrangements between Hangzhou Weimi, our VIE and its shareholders governed by PRC law are legal, valid, binding and enforceable in accordance with its terms and applicable PRC laws. However, our PRC legal counsel has also advised us 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 take a view that is contrary to the opinion of our PRC legal counsel. It is uncertain whether any new PRC laws or regulations relating to variable interest entity structures will be adopted or if adopted, what they would provide. If we or our VIE are found to be in violation of any existing or future PRC laws or regulations, or fail to obtain or maintain any of the required permits or approvals, the relevant PRC regulatory authorities would have broad discretion to take action in dealing with such violations or failures, including:

•

revoking the business license and/or operating license of such entities;



•

discontinuing or placing restrictions or onerous conditions on our operations;



•

imposing fines, confiscating the income from Hangzhou Weimi or our VIE, or imposing other requirements with which we or our VIE may not be able to comply;



•

requiring us to restructure our ownership structure or operations, including terminating the contractual arrangements with our VIE and deregistering the equity pledges of our VIE, which

S-42

---

Table of Contents

in turn would affect our ability to consolidate, derive economic interests from, or exert effective control over our VIE; or

•

restricting or prohibiting our use of the proceeds of offshore financing to finance our business and operations in China.

        The imposition of any of these penalties would result in a material and adverse effect on our ability to conduct our business. In addition, it is unclear what impact the PRC government actions would have on us and on our ability to consolidate the financial results of our VIE in our consolidated financial statements, if the PRC government authorities were to find our legal structure and contractual arrangements to be in violation of PRC laws and regulations. If the imposition of any of these government actions causes us to lose our right to direct the activities of our VIE or our right to receive substantially all the economic benefits and residual returns from our VIE and we are not able to restructure our ownership structure and operations in a satisfactory manner, we would no longer be able to consolidate the financial results of our VIE in our consolidated financial statements. Either of these results, or any other significant penalties that might be imposed on us in this event, would have a material adverse effect on our financial condition and results of operations.

We face uncertainties with respect to the implementation of the Foreign Investment Law and how it may impact the viability of our current corporate structure, corporate governance and business operations.

        On March 15, 2019, the National People's Congress approved the Foreign Investment Law, which has taken effect on January 1, 2020 and replaced the Sino-Foreign Equity Joint Venture Enterprise Law, the Sino-Foreign Cooperative Joint Venture Enterprise Law and the Foreign Owned Enterprise Law, together with their implementation rules and ancillary regulations, to become the legal foundation for foreign investment in the PRC. The Foreign Investment Law embodies the legislative efforts to unify the corporate legal requirements for both foreign and domestic investments. Under the Foreign Investment Law, "foreign investment" refers to the investment activities directly or indirectly conducted by foreign individuals, enterprises or other foreign entities in China. The Foreign Investment Law stipulates three forms of foreign investment, and does not explicitly stipulate contractual arrangements as a form of foreign investment. On December 26, 2019, the State Council promulgated the Implementation Regulations on the Foreign Investment Law, which came into effect on January 1, 2020. The Implementation Regulations on the Foreign Investment Law does not stipulate whether contractual arrangements should be deemed as a form of foreign investment. Before clarification or confirmation by future laws, administrative regulations or provisions promulgated by the State Council on nature of contractual arrangements, there is no assurance that contractual arrangement would not be considered as foreign investment under the Foreign Investment Law. In addition, the Foreign Investment Law stipulates that activities constituting "foreign investment" includes foreign investors investing in China through "any other methods" under laws, administrative regulations, or provisions prescribed by the State Council. The State Council may in the future enact laws or issue administrative regulations or provisions to classify contractual arrangements as a form of foreign investment, at which time it would be uncertain as to regulation on such contractual arrangements and whether such contractual arrangements would be deemed to be in violation of the foreign investment restrictions. There is no guarantee that our contractual arrangements and our business will not be materially and adversely affected in the future due to changes in PRC laws and regulations. If future laws, administrative regulations or provisions prescribed by the State Council mandate further actions to be completed by companies with existing contractual arrangements, we may face substantial uncertainties as to the timely completion of such actions. Failure to take timely and appropriate measures to cope with any of these or similar regulatory compliance challenges could materially and adversely affect our current corporate structure and business operations.

The rights and functions of the Pinduoduo Partnership, once effective, may impact your ability to appoint executive directors and nominate the chief executive officer of the company, and the interests of the Pinduoduo Partnership may conflict with your interests.

        Under our currently effective articles of association, the Pinduoduo Partnership, upon and for so long as certain conditions are satisfied, will be entitled to nominate two executive directors (if there are no more than 5 directors on the board of directors) or three executive directors (if there are more than 5 but no more than 9 directors on the board of directors) and nominate the chief executive officer candidate of our company. Such executive director candidate duly nominated by the Pinduoduo Partnership shall be approved and appointed by our board of directors and serve as an executive director of our company until expiry of his or her terms (if any), removal by the Pinduoduo Partnership, the shareholders by an ordinary resolution or vacation of office if such executive director, among other things, resigns his office by notice in writing to us or dies or is found to be or becomes of unsound mind. The chief executive officer candidate nominated by the Pinduoduo Partnership shall stand for appointment by the nominating and corporate governance committee of the board of directors. If the candidate is not appointed by the nominating and corporate governance committee in accordance with the then effective articles of association of the company, the Pinduoduo Partnership may nominate a replacement nominee until the nominating and corporate governance committee appoints such nominee as chief executive officer, or if the nominating and corporate governance committee fails to appoint more than three candidates nominated by the Pinduoduo Partnership consecutively, the board of directors may then nominate and appoint any person to serve as our chief executive officer in accordance with the then effective articles of association of the company. See "Item 6. Directors, Senior Management and Employees—A. Directors and Senior Management—Pinduoduo Partnership" in our 2019 Annual Report. This governance structure and contractual arrangements will limit your ability to influence corporate matters, including the matters determined at the board level.

        In addition, the interests of the Pinduoduo Partnership may not coincide with your interests, including certain managerial decisions such as partner compensation. For example, each year, once an aggregate bonus pool is approved by the board of directors, the partnership committee of the Pinduoduo Partnership will make further determinations as to, among other things, the allocation of the current bonus pool among all partners and these allocations may not be entirely aligned with the interest of shareholders who are not partners. Because the partners may be largely comprised of members of our management team, the Pinduoduo Partnership and its executive director nominees may focus on the operational and financial results that may differ from the expectations and desires of shareholders. To the extent that the interests of the Pinduoduo Partnership differ from your interests on certain matters, you may be disadvantaged.

We rely on contractual arrangements with our VIE and its shareholders for a large portion of our business operations, which may not be as effective as direct ownership in providing operational control.

        Our VIE contributed 100%, 77.3%, 58.5% and 61.2% of our consolidated total revenues in 2017, 2018, 2019 and the nine months ended September 30, 2020, respectively. We have relied and expect to continue to rely on contractual arrangements with our VIE and its shareholders to conduct our business. For a description of these contractual arrangements, see "Item 4. Information on the Company—C. Organizational Structure" in our 2019 Annual Report. These contractual arrangements may not be as effective as direct ownership in providing us with control over our VIE. For example, our VIE and its shareholders could breach their contractual arrangements with us by, among other things, failing to conduct their operations in an acceptable manner or taking other actions that are detrimental to our interests.

        If we had direct ownership of our VIE, we would be able to exercise our rights as a shareholder to effect changes in the board of directors of our VIE, which in turn could implement changes, subject to

S-44

Table of Contents

any applicable fiduciary obligations, at the management and operational level. However, under the current contractual arrangements, we rely on the performance by our VIE and its shareholders of their obligations under the contracts to exercise control over our VIE. The shareholders of our consolidated VIE may not act in the best interests of our company or may not perform their obligations under these contracts. Such risks exist throughout the period in which we intend to operate certain portions of our business through the contractual arrangements with our VIE. If any dispute relating to these contracts remains unresolved, we will have to enforce our rights under these contracts through the operations of PRC law and arbitration, litigation and other legal proceedings and therefore will be subject to uncertainties in the PRC legal system. See "Risks Related to Our Corporate Structure—Any failure by our VIE or its shareholders to perform their obligations under our contractual arrangements with them would have a material and adverse effect on our business." Therefore, our contractual arrangements with our VIE may not be as effective in ensuring our control over the relevant portion of our business operations as direct ownership would be.

Any failure by our VIE or its shareholders to perform their obligations under our contractual arrangements with them would have a material and adverse effect on our business.

        Although the shareholders of our VIE hold equity interests on record in our VIE, each such shareholder has irrevocably authorized Hangzhou Weimi to exercise his rights as a shareholder of our VIE pursuant to the terms of the relevant shareholders' voting rights proxy agreement. However, if our VIE or its shareholders fail to perform their respective obligations under the contractual arrangements, we may have to incur substantial costs and expend additional resources to enforce such arrangements. We may also have to rely on legal remedies under PRC law, including seeking specific performance or injunctive relief, and claiming damages, which may not be effective under PRC law. For example, if the shareholders of our VIE refuse to transfer their equity interest in our VIE to us or our designee if we exercise the purchase option pursuant to these contractual arrangements, or if they otherwise act in bad faith toward us, then we may have to take legal actions to compel them to perform their contractual obligations.

        All of the agreements under our contractual arrangements are governed by PRC law and provide for the resolution of disputes through arbitration in China. Accordingly, these contracts would be interpreted in accordance with PRC law and any disputes would be resolved in accordance with PRC legal procedures. The legal system in the PRC is not as developed as in some other jurisdictions, such as the United States. As a result, uncertainties in the PRC legal system could limit our ability to enforce these contractual arrangements. See "Risks Related to Doing Business in China—Uncertainties with respect to the PRC legal system and changes in laws and regulations in China could adversely affect us." Meanwhile, there are very few precedents and little formal guidance as to how contractual arrangements in the context of a VIE should be interpreted or enforced under PRC law. There remain significant uncertainties regarding the ultimate outcome of such arbitration should legal action become necessary. In addition, under PRC law, rulings by arbitrators are final, parties cannot appeal the arbitration results in courts, and if the losing parties fail to carry out the arbitration awards within a prescribed time limit, the prevailing parties may only enforce the arbitration awards in PRC courts through arbitration award recognition proceedings, which would require additional expenses and delay. In the event we are unable to enforce these contractual arrangements, or if we suffer significant delays or other obstacles in the process of enforcing these contractual arrangements, we may not be able to exert effective control over our VIE, and our ability to conduct our business may be negatively affected.

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

        Messrs. Lei Chen and Jianchong Zhu hold 86.6% and 13.4% equity interests in our VIE, respectively. They are employees of our company and have entered into a series of contractual arrangements with Hangzhou Weimi, pursuant to which we have control over and are the primary beneficiary of our VIE. These shareholders of our VIE may have potential conflicts of interest with us. See "Item 4. Information on the Company—C. Organizational Structure" in our 2019 Annual Report. These shareholders may breach, or cause our VIE to breach, or refuse to renew, the existing contractual arrangements we have with them and our VIE, which would have a material and adverse effect on our ability to effectively control our VIE and receive economic benefits from it. For example, the shareholders may be able to cause our agreements with our VIE to be performed in a manner adverse to us by, among other things, failing to remit payments due under the contractual arrangements to us on a timely basis. We cannot assure you that when conflicts of interest arise any or all of these shareholders will act in the best interests of our company or such conflicts will be resolved in our favor.

        Currently, we do not have any arrangements to address potential conflicts of interest between these shareholders and our company, except that we could exercise our purchase option under the exclusive option agreements with these shareholders to request them to transfer all of their equity interests in the VIE to a PRC entity or individual designated by us, to the extent permitted by PRC law. We also rely on these shareholders to abide by the laws of the Cayman Islands, which provide that directors and officers owe a fiduciary duty to the company that requires them to act in good faith and in what they believe to be the best interests of the company and not to use their position for personal gains. The shareholders of our VIE have executed shareholders' voting rights proxy agreement to appoint Hangzhou Weimi or a person designated by Hangzhou Weimi to vote on their behalf and exercise voting rights as shareholders of our VIE. If we cannot resolve any conflict of interest or dispute between us and the shareholders of our variable interest entities, we would have to rely on legal proceedings, which could result in disruption of our business and subject us to substantial uncertainty as to the outcome of any such legal proceedings.

        The shareholders of our VIE may be involved in personal disputes with third parties or other incidents that may have an adverse effect on their respective equity interests in our VIE and the validity or enforceability of our contractual arrangements with the relevant entity and its shareholders. For example, in the event that any of the shareholders of our VIE divorces his spouse, the spouse may claim that the equity interest of our VIE held by such shareholder is part of their community property and should be divided between such shareholder and his spouse. If such claim is supported by the court, the relevant equity interest may be obtained by the shareholder's spouse or another third party who is not subject to obligations under our contractual arrangements, which could result in a loss of the effective control over our VIE by us. Similarly, if any of the equity interests of our VIE is inherited by a third party with whom the current contractual arrangements are not binding, we could lose our control over our VIE or have to maintain such control by incurring unpredictable costs, which could cause significant disruption to our business and operations and harm our financial condition and results of operations.

        Although under our current contractual arrangements, (i) to the extent applicable, the spouse of each of the shareholders of our VIE has executed a spousal consent letter, under which the spouse agrees not to raise any claim against the equity interest, and to take every action to ensure the performance of the contractual arrangements, and (ii) it is expressly provided that the rights and obligations under the contractual agreements shall be equally effective and binding on the heirs and successors of the parties thereto, or that our VIE shall not assign or delegate its rights and obligations under the contractual agreements to third parties without our prior consent, we cannot assure you that these undertakings and arrangements will be complied with or effectively enforced. In the case any of them is breached or becomes unenforceable and leads to legal proceedings, it could disrupt our business, distract our management's attention and subject us to substantial uncertainties as to the outcome of any such legal proceedings.

Contractual arrangements in relation to our VIE may be subject to scrutiny by the PRC tax authorities and they may determine that we or our VIE owes additional taxes, which could negatively affect our financial condition and the value of your investment.

        Under applicable PRC laws and regulations, arrangements and transactions among related parties may be subject to audit or challenge by the PRC tax authorities. We could face material and adverse tax consequences if the PRC tax authorities determine that the VIE contractual arrangements were not entered into on an arm's length basis in such a way as to result in an impermissible reduction in taxes under applicable PRC laws, rules and regulations, and adjust the income of our VIE in the form of a transfer pricing adjustment. A transfer pricing adjustment could, among other things, result in a reduction of expense deductions recorded by our VIE for PRC tax purposes, which could in turn increase its tax liabilities without reducing Hangzhou Weimi's tax expenses. In addition, the PRC tax authorities may impose late payment fees and other penalties on our VIE for the adjusted but unpaid taxes according to the applicable regulations. Our financial position could be materially and adversely affected if our VIE's tax liabilities increase or if it is required to pay late payment fees and other penalties.

We may lose the ability to use and enjoy assets held by our VIE that are material to the operation of certain portion of our business if the VIE goes bankrupt or become subject to a dissolution or liquidation proceeding.

        As part of our contractual arrangements with our VIE, our VIE and its subsidiaries hold certain assets that are material to the operation of certain portion of our business, including intellectual property and premise and VATS licenses. If our VIE goes bankrupt and all or part of its assets become subject to liens or rights of third-party creditors, we may be unable to continue some or all of our business activities, which could materially and adversely affect our business, financial condition and results of operations. Under the contractual arrangements, our VIE may not, in any manner, sell, transfer, mortgage or dispose of their assets or legal or beneficial interests in the business without our prior consent. If our VIE undergoes a voluntary or involuntary liquidation proceeding, independent third-party creditors may claim rights to some or all of these assets, thereby hindering our ability to operate our business, which could materially and adversely affect our business, financial condition and results of operations.

If the chops of our PRC subsidiaries and our VIE 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 and VIE 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 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 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. In addition, if the chops are misused by unauthorized persons, we could experience disruption to our normal business operations. We may have to take corporate or legal action, which could involve significant time and resources to resolve while distracting management from our operations.

Risks Related to Doing Business in China

Changes in China's economic, political or social conditions or government policies could have a material adverse effect on our business and operations.

        Substantially all of our assets and operations are located in China. Accordingly, our business, financial condition, results of operations and prospects may be influenced to a significant degree by political, economic and social conditions in China generally. The Chinese economy differs from the economies of most developed countries in many respects, including the level of government involvement, level of development, growth rate, control of foreign exchange and allocation of resources. Although the Chinese government has implemented measures emphasizing the utilization of market forces for economic reform, the reduction of state ownership of productive assets, and the establishment of improved corporate governance in business enterprises, a substantial portion of productive assets in China is still owned by the government. In addition, the Chinese government continues to play a significant role in regulating industry development by imposing industrial policies.

        The Chinese government also exercises significant control over China's economic growth through allocating resources, controlling payment of foreign currency-denominated obligations, setting monetary policy, and providing preferential treatment to particular industries or companies.

        While the Chinese economy has experienced significant growth over the past decades, growth has been uneven, both geographically and among various sectors of the economy, and the rate of growth has been slowing since 2012. According to the National Bureau of Statistics of China, China's real GDP growth rate was 6.9% in 2017, which slowed to 6.7% in 2018, and further slowed to 6.1% in 2019. There have also been concerns about the relationships among China and other Asian countries, the relationship between China and the United States, as well as the relationship between the United States and certain Asian countries such as North Korea, which may result in or intensify potential conflicts in relation to territorial, regional security and trade disputes. Any adverse changes in economic conditions in China, in the policies of the Chinese 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. Any disruptions or continuing or worsening slowdown could significantly reduce domestic commerce activities in China, which could lead to significant reduction in merchants' demand for and spending on the various services we offer. An economic downturn, whether actual or perceived, a further decrease in economic growth rates or an otherwise uncertain economic outlook in China could have a material adverse effect on business and consumer spending and, as a result, adversely affect our business, financial condition and results of operations. The Chinese government has implemented various measures to encourage economic growth and guide the allocation of resources. Some of these measures may benefit the overall Chinese economy, but may have a negative effect on us. For example, our financial condition and results of operations may be adversely affected by government control over capital investments or changes in tax regulations. The growth rate of the Chinese economy has gradually slowed since 2010, and the impact of COVID-19 on the Chinese economy in 2020 is likely to be severe. Any prolonged slowdown in the Chinese economy may reduce the demand for our services and materially and adversely affect our business and results of operations.

        In addition, because we hold a significant amount of cash and cash equivalents and short-term investments, if financial institutions and issuers of financial instruments that we hold become insolvent or if the market for these financial instruments become illiquid as a result of a severe economic downturn, our business and financial condition could be materially and adversely affected.

Uncertainties with respect to the PRC legal system and changes in laws and regulations in China could adversely affect us.

        We conduct our business primarily through our PRC subsidiaries and our VIE and one of its subsidiaries in China. Our operations in China are governed by PRC laws and regulations. Our PRC subsidiaries are subject to laws and regulations applicable to foreign investment in China. The PRC legal system is a civil law system based on written statutes. Unlike the common law system, prior court decisions under the civil law system may be cited for reference but have limited precedential value. In addition, any new or changes in PRC laws and regulations related to foreign investment in China could affect the business environment and our ability to operate our business in China.

        From time to time, we may have to resort to administrative and court proceedings to enforce our legal rights. Any administrative and court proceedings in China may be protracted, resulting in substantial costs and diversion of resources and management attention. Since PRC administrative and court authorities have significant discretion in interpreting and implementing statutory provisions and contractual terms, it may be more difficult to evaluate the outcome of administrative and court proceedings and the level of legal protection we enjoy than in more developed legal systems. These uncertainties may impede our ability to enforce the contracts we have entered into and could materially and adversely affect our business and results of operations.

        Furthermore, the PRC legal system is based in part on government policies and internal rules, some of which are not published on a timely basis or at all and may have retroactive effect. As a result, we may not be aware of our violation of any of these policies and rules until sometime after the violation. Such unpredictability towards our contractual, property and procedural rights could adversely affect our business and impede our ability to continue our operations.

We may be adversely affected by the complexity, uncertainties and changes in PRC regulation of internet-related businesses and companies, and any lack of requisite approvals, licenses or permits applicable to our business may have a material adverse effect on our business and results of operations.

        The PRC government extensively regulates the internet industry, including foreign ownership of, and the licensing and permit requirements pertaining to, companies in the internet industry. These internet-related laws and regulations are relatively new and evolving, and their interpretation and enforcement involve significant uncertainties. As a result, in certain circumstances it may be difficult to determine what actions or omissions may be deemed to be in violation of applicable laws and regulations.

        We only have contractual control over our Pinduoduo mobile app. We do not directly own the mobile app due to the restrictions on foreign investment in businesses providing value-added telecommunications services in China, including e-commerce services and internet content-related services. This may significantly disrupt our business, subject us to sanctions, compromise enforceability of related contractual arrangements, or have other harmful effects on us.

        The evolving PRC regulatory system for the internet industry may lead to the establishment of new regulatory agencies. For example, in May 2011, the State Council announced the establishment of the State Internet Information Office (with the involvement of the State Council Information Office, MIIT, and the Ministry of Public Security). The primary role of the State Internet Information Office is to facilitate the policy-making and legislative development in this field, to direct and coordinate with the relevant departments in connection with online content administration and to deal with cross-ministry regulatory matters in relation to the internet industry.

        The Circular on Strengthening the Administration of Foreign Investment in and Operation of Value-added Telecommunications Business, issued by the MIIT in July 2006, prohibits domestic telecommunications service providers from leasing, transferring or selling telecommunications business

operating licenses to any foreign investor in any form, or providing any resources, sites or facilities to any foreign investor for their illegal operation of a telecommunications business in China. According to this circular, either the holder of a value-added telecommunications services operation permit or its shareholders must directly own the domain names and trademarks used by such license holders in their provision of value-added telecommunications services. The circular also requires each license holder to have the necessary facilities, including servers, for its approved business operations and to maintain such facilities in the regions covered by its license. Shanghai Xunmeng owns the relevant domain names and trademarks in connection with our online platform and has the necessary personnel to operate our online platform.

        The interpretation and application of existing PRC laws, regulations and policies and possible new laws, regulations or policies relating to the internet industry have created substantial uncertainties regarding the legality of existing and future foreign investments in, and the businesses and activities of, internet businesses in China, including our business. We cannot assure you that we have obtained all the permits or licenses required for conducting our business in China or will be able to maintain our existing licenses or obtain new ones. If the PRC government considers that we were operating without the proper approvals, licenses or permits or promulgates new laws and regulations that require additional approvals or licenses or imposes additional restrictions on the operation of any part of our business, it has the power, among other things, to levy fines, confiscate our income, revoke our business licenses, and require us to discontinue our relevant business or impose restrictions on the affected portion of our business. Any of these actions by the PRC government may have a material adverse effect on our business and results of operations.

Discontinuation of any preferential tax treatments or imposition of any additional taxes could adversely affect our financial condition and results of operations.

        Shanghai Xunmeng, a subsidiary of our VIE, was recognized as a "high and new technology enterprise" in November 2018 and was eligible for a preferential tax rate of 15% from 2018 to 2020. In April 2018, Shenzhen Qianhai Xinzhijiang Information Technology Co., Ltd., a subsidiary of ours located in Qianhai District, Shenzhen, Guangdong Province, was eligible for a preferential tax rate of 15% and has been applying such preferential tax rate since then. The preferential tax rate is available from 2014 to 2020 and is awarded to companies located in Qianhai District that operate in certain encouraged industries. Government subsidies and preferential tax treatments are subject to discretions of the relevant governmental authorities and our eligibility for them are therefore out of our control. Discontinuation of any preferential tax treatments or imposition of any additional taxes could adversely affect our financial condition and results of operations.

You may experience difficulties in effecting service of legal process, enforcing foreign judgments or bringing actions in China against us or our management named in our 2019 Annual Report based on foreign laws.

        We are an exempted company incorporated under the laws of the Cayman Islands, we conduct substantially all of our operations in China and substantially all of our assets are located in China. In addition, all our senior executive officers reside within China for a significant portion of the time and most are PRC nationals. As a result, it may be difficult for you to effect service of process upon us or those persons inside mainland China. It may also be difficult for you to enforce in U.S. courts 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 as most of our current directors and officers are nationals and residents of countries other than the United States and substantially all of the assets of these persons are located outside the United States. In addition, there is uncertainty as to whether the courts of the Cayman Islands or the PRC would recognize or enforce judgments of U.S. courts against us or such persons predicated upon the civil liability provisions of the securities laws of the United States or any state.

        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 forms of written arrangement with the United States that provide for the reciprocal recognition and enforcement of foreign judgments. In addition, according to the PRC Civil Procedures Law, the PRC courts 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 laws 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.

We may rely on dividends and other distributions on equity paid by our PRC subsidiaries to fund any cash and financing requirements we may have, and any limitation on the ability of our PRC subsidiaries to make payments to us could have a material and adverse effect on our ability to conduct our business.

        We are a Cayman Islands holding company and we rely principally on dividends and other distributions on equity from our PRC subsidiaries for our cash requirements, including the funds necessary to pay dividends and other cash distributions to our shareholders for services of any debt we may incur. If any of our PRC subsidiaries incur debt on its own behalf in the future, the instruments governing the debt may restrict its ability to pay dividends or make other distributions to us. Under PRC laws and regulations, our PRC subsidiaries, each of which is a wholly foreign-owned enterprise may pay dividends only out of its respective 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, if any, to fund a certain statutory reserve fund, until the aggregate amount of such fund reaches 50% of its registered capital. At its discretion, a wholly foreign-owned enterprise may allocate a portion of its after-tax profits based on PRC accounting standards to a staff welfare and bonus fund. These reserve fund and staff welfare and bonus fund cannot be distributed to us as dividends.

        Our PRC subsidiaries generate primarily all of their revenue in Renminbi, which is not freely convertible into other currencies. As result, any restriction on currency exchange may limit the ability of our PRC subsidiaries to use their Renminbi revenues to pay dividends to us.

        The PRC government may continue to strengthen its capital controls, and more restrictions and substantial vetting process may be put forward by SAFE for cross-border transactions falling under both the current account and the capital account. Any limitation on the ability of our PRC subsidiaries to pay dividends or make other kinds of payments 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.

        In addition, the Enterprise Income Tax Law and its implementation rules provide that a withholding tax rate of up to 10% will be applicable to dividends payable by Chinese companies to non-PRC-resident enterprises unless otherwise exempted or reduced according to treaties or arrangements between the PRC central government and governments of other countries or regions where the non-PRC-resident enterprises are incorporated.

PRC regulation of loans to and direct investment in PRC entities by offshore holding companies and governmental control of currency conversion may delay or prevent us from using the proceeds from this offering and our concurrent Convertible Notes Offering to make loans or additional capital contributions to our PRC subsidiaries, which could materially and adversely affect our liquidity and our ability to fund and expand our business.

        We are an offshore holding company conducting our operations in China. We may make loans to our PRC subsidiaries and VIE subject to the approval, registration, and filing with governmental authorities and limitation of amount, or we may make additional capital contributions to our wholly foreign-owned subsidiaries in China. Any loans to our wholly foreign-owned subsidiaries in China, which are treated as foreign-invested enterprises under PRC law, are subject to foreign exchange loan registrations. In addition, a foreign invested enterprise shall use its capital pursuant to the principle of authenticity and self-use within its business scope. The capital of a foreign invested enterprise shall not be used for the following purposes: (i) directly or indirectly used for payment beyond the business scope of the enterprises or the payment prohibited by relevant laws and regulations; (ii) directly or indirectly used for investment in securities or investments other than banks' principal-secured products unless otherwise provided by relevant laws and regulations; (iii) the granting of loans to non-affiliated enterprises, except where it is expressly permitted in the business license; and (iv) paying the expenses related to the purchase of real estate that is not for self-use (except for the foreign-invested real estate enterprises).

        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 or filings on a timely basis, if at all, with respect to future loans by us to our PRC subsidiary or VIE 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 from this offering and our concurrent Convertible Notes 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.

Fluctuations in exchange rates could have a material and adverse effect on our results of operations and the value of your investment.

        The conversion of Renminbi into foreign currencies, including U.S. dollars, is based on rates set by the People's Bank of China. The Renminbi has fluctuated against the U.S. dollar, at times significantly and unpredictably. The value of Renminbi against the U.S. dollar and other currencies is affected by changes in China's political and economic conditions and by China's foreign exchange policies, among other things. 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.

        Any significant appreciation or depreciation of Renminbi may materially and adversely affect our revenues, earnings and financial position, and the value of, and any dividends payable on, our ADSs in U.S. dollars. For example, to the extent that we need to convert U.S. dollars we receive from this offering or our concurrent Convertible Notes Offering into Renminbi for our operations, appreciation of the Renminbi against the U.S. dollar would have an adverse effect on the Renminbi amount we would receive from the conversion. Conversely, if we decide to convert our Renminbi into U.S. dollars for the purpose of making payments for dividends on our ordinary shares or ADSs, payments when due on the convertible notes and the 2024 Notes or for other business purposes, appreciation of the U.S. dollar against the Renminbi would have a negative effect on the U.S. dollar amount available to us.

        Very limited hedging options are available in China to reduce our exposure to exchange rate fluctuations. As of September 30, 2020, we had used some hedging transactions in an effort to reduce our exposure to foreign currency exchange risk. While we may decide to enter into hedging transactions in the future, the availability and effectiveness of these hedges may be limited and we may not be able to adequately hedge our exposure or at all. In addition, our currency exchange losses may be magnified by PRC exchange control regulations that restrict our ability to convert Renminbi into foreign currency. As a result, fluctuations in exchange rates may have a material adverse effect on your investment.

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 subsidiary 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 subsidiary 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 subsidiary and VIE 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 from China, the PRC government may from time to time impose more restrictive foreign exchange policies and step up scrutiny of major outbound capital movement. More restrictions and substantial vetting process may be required by SAFE or other government authorities to regulate cross-border transactions falling under the capital account. The PRC government may at its discretion restrict access to foreign currencies for current account transactions in the future. 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.

Certain PRC regulations may make it more difficult for us to pursue growth through acquisitions.

        Among other things, the Regulations on Mergers and Acquisitions of Domestic Enterprises by Foreign Investors, or the M&A Rules, adopted by six PRC regulatory agencies in 2006 and amended in 2009, established additional procedures and requirements that could make merger and acquisition activities by foreign investors more time-consuming and complex. Such regulation requires, among other things, that MOFCOM be notified in advance of any change-of-control transaction in which a foreign investor acquires control of a PRC domestic enterprise and involves any of the following circumstances: (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 NPC which became effective in 2008 requires that transactions which are deemed concentrations and involve parties with specified turnover thresholds must be cleared by MOFCOM before they can be completed. In addition, PRC national security review rules that became effective in September 2011 require acquisitions by foreign

investors of PRC companies engaged in military related or certain other industries that are crucial to national security be subject to security review before consummation of any such acquisition. We may pursue potential strategic acquisitions that are complementary to our business and operations. Complying with the requirements of these regulations to complete such transactions could be time-consuming, and any required approval processes, including obtaining approval or clearance from MOFCOM, may delay or inhibit our ability to complete such transactions, which could affect our ability to expand our business or maintain our market share.

PRC regulations relating to offshore investment activities by PRC residents may limit our PRC subsidiaries' ability to change their registered capital or distribute profits to us or otherwise expose us or our PRC resident beneficial owners to liability and penalties under PRC laws.

        In July 2014, SAFE promulgated the Circular on Relevant Issues Concerning Foreign Exchange Control on Domestic Residents' Offshore Investment and Financing and Roundtrip Investment Through Special Purpose Vehicles, or SAFE Circular 37. SAFE Circular 37 requires PRC residents (including PRC individuals and PRC corporate entities as well as foreign individuals that are deemed as PRC residents for foreign exchange administration purpose) to register with SAFE or its local branches in connection with their direct or indirect offshore investment activities. SAFE Circular 37 further requires amendment to the SAFE registrations in the event of any changes with respect to the basic information of the offshore special purpose vehicle, such as change of a PRC individual shareholder, name and operation term, or any significant changes with respect to the offshore special purpose vehicle, such as increase or decrease of capital contribution, share transfer or exchange, or mergers or divisions. SAFE Circular 37 is applicable to our shareholders who are PRC residents and may be applicable to any offshore acquisitions that we make in the future.

        If our shareholders who are PRC residents fail to make the required registration or to update the previously filed registration, our PRC subsidiaries may be prohibited from distributing their profits or the proceeds from any capital reduction, share transfer or liquidation to us, and we may also be prohibited from making additional capital contributions into our PRC subsidiaries. In February 2015, SAFE promulgated a Notice on Further Simplifying and Improving Foreign Exchange Administration Policy on Direct Investment, or SAFE Notice 13, effective June 2015. Under SAFE Notice 13, applications for foreign exchange registration of inbound foreign direct investments and outbound overseas direct investments, including those required under SAFE Circular 37, will be filed with qualified banks instead of SAFE. The qualified banks will directly examine the applications and accept registrations under the supervision of SAFE.

        All of our shareholders who we are aware of being subject to the SAFE regulations have completed the initial registrations with the local SAFE branch or qualified banks as required by SAFE Circular 37. However, we may not be informed of the identities of all the PRC residents holding direct or indirect interest in our company, and we cannot provide any assurance that these PRC residents will comply with our request to make or obtain any applicable registrations or continuously comply with all requirements under SAFE Circular No. 37 or other related rules. The failure or inability of the relevant shareholders to comply with the registration procedures set forth in these regulations may subject us to fines and legal sanctions, such as restrictions on our cross-border investment activities, on the ability of our wholly foreign-owned subsidiaries in China to distribute dividends and the proceeds from any reduction in capital, share transfer or liquidation to us. Moreover, failure to comply with the various foreign exchange registration requirements described above could result in liability under PRC law for circumventing applicable foreign exchange restrictions. As a result, our business operations and our ability to distribute profits to you could be materially and adversely affected.

Any failure to comply with PRC regulations regarding the registration requirements for employee stock incentive plans may subject the PRC plan participants or us to fines and other legal or administrative sanctions.

        In February 2012, SAFE promulgated the Notices on Issues Concerning the Foreign Exchange Administration for Domestic Individuals Participating in Stock Incentive Plan of Overseas Publicly Listed Company, replacing earlier rules promulgated in 2007. Pursuant to these rules, PRC citizens and non-PRC citizens who reside in China for a continuous period of not less than one year who participate in any stock incentive plan of an overseas publicly listed company, subject to a few exceptions, are required to register with SAFE through a domestic qualified agent, which could be the PRC subsidiaries of such overseas-listed company, and complete certain other procedures. In addition, an overseas-entrusted institution must be retained to handle matters in connection with the exercise or sale of stock options and the purchase or sale of shares and interests. We and our executive officers and other employees who are PRC citizens or who reside in the PRC for a continuous period of not less than one year and who have been granted options are subject to these regulations as our company is an overseas-listed company. Failure to complete SAFE registrations may subject them to fines of up to RMB300,000 for entities and up to RMB50,000 for individuals, and legal sanctions and may also limit our ability to contribute additional capital into our PRC subsidiary and limit our PRC subsidiary's ability to distribute dividends to us. We also face regulatory uncertainties that could restrict our ability to adopt additional incentive plans for our directors, executive officers and employees under PRC law. See "Item 4. Information on the Company—B. Business Overview—Regulation—Regulations Relating to Foreign Exchange—Regulations on Stock Incentive Plans" in our 2019 Annual Report.

        In addition, the State Administration of Taxation, or SAT, has issued certain circulars concerning employee share options and restricted shares. Under these circulars, our employees working in China who exercise share options or are granted restricted shares will be subject to PRC individual income tax. Our PRC subsidiaries have obligations to file documents related to employee share options or restricted shares 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 government authorities. See "Item 4. Information on the Company—B. Business Overview—Regulation—Regulations Relating to Foreign Exchange—Regulations on Stock Incentive Plans" in our 2019 Annual Report.

Our use of some leased properties could be challenged by third parties or government authorities, which may cause interruptions to our business operations.

        Certain of our leasehold interests in leased properties have not been registered with the relevant PRC government authorities as required by PRC law, which may expose us to potential fines if we fail to remediate after receiving notice from the relevant PRC government authorities. In case of failure to register or file a lease, the parties to the unregistered lease may be ordered to make rectifications (which would involve registering such lease with the relevant authority) before being subject to penalties. The penalty ranges from RMB1,000 to RMB10,000 for each unregistered lease, at the discretion of the relevant authority. The law is not clear as to which of the parties, the lessor or the lessee, is liable for the failure to register the lease. Although we have proactively requested that the applicable lessors complete or cooperate with us to complete the registration in a timely manner, we are unable to control whether and when such lessors will do so. In the event that a fine or a portion thereof is imposed on the lessee, and if we are unable to recover from the lessor any fine paid by us, such fine will be borne by us. Moreover, certain lessors have not provided us with valid ownership certificates or authorization of sublease for our leased properties. As a result, there is a risk that these lessors may not have the right to lease such properties to us, in which case the relevant lease agreements may be deemed invalid or we may face challenges from the property owners or other third

parties regarding our right to occupy the premises. We are not aware of any actions, claims or investigations being initiated by third parties or competent governmental authorities with respect to the defects in our leased real properties. However, if we are unable to continue our operations on the current premises and cannot find a suitable replacement in a timely manner, our business, results of operations and financial condition could be materially and adversely affected.

If we are classified as a PRC resident enterprise for PRC income tax purposes, such classification could result in unfavorable tax consequences to us and our non-PRC shareholders or ADS holders.

        Under the PRC Enterprise Income Tax Law and its implementation rules, an enterprise established outside of the PRC with "de facto management body" within the PRC is considered a "resident enterprise" and will be subject to the enterprise income tax on its global income at the rate of 25%. 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 2009, the State Administration of Taxation, or SAT, issued a circular, known as 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. 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 SAT'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 SAT 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 and will be subject to PRC enterprise income tax on its global income only if all of the following conditions are met: (i) the primary location of the day-to-day operational management is in the PRC; (ii) decisions relating to the enterprise's financial and human resource matters are made or are subject to approval by organizations or personnel in the PRC; (iii) the enterprise's primary assets, accounting books and records, company seals, and board and shareholder resolutions, are located or maintained in the PRC; and (iv) at least 50% of voting board members or senior executives habitually reside in the PRC.

        We believe that we are not a PRC resident enterprise for PRC tax purposes. 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 we are a PRC resident enterprise for enterprise income tax purposes, we could be subject to PRC tax at a rate of 25% on our worldwide income, which could materially reduce our net income, and 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 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 the PRC. Furthermore, if we are deemed a PRC resident enterprise, dividends payable to our non-PRC individual shareholders (including our ADS holders) and any gain realized on the transfer of ADSs or ordinary shares by such shareholders may be subject to PRC tax at a rate of 10% in the case of non-PRC enterprises or a rate of 20% in the case of non-PRC individuals unless a reduced rate is available under an applicable tax treaty. It is unclear whether non-PRC shareholders of our company would be able to claim the benefits of any tax treaties between their country of tax residence and the PRC in the event that we are treated as a PRC resident enterprise. Any such tax may reduce the returns on your investment in the ADSs or ordinary shares.

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

        Pursuant to the Notice on Strengthening Administration of Enterprise Income Tax for Share Transfers by Non-PRC Resident Enterprises, or SAT Circular 698, issued by SAT in 2009 with retroactive effect from January 1, 2008, where a non-resident enterprise transfers the equity interests of a PRC resident enterprise indirectly by disposition of the equity interests of an overseas holding company, or an Indirect Transfer, and such overseas holding company is located in a tax jurisdiction that: (i) has an effective tax rate less than 12.5% or (ii) does not tax foreign income of its residents, the non-resident enterprise, being the transferor, shall report to the competent tax authority of the PRC resident enterprise this Indirect Transfer.

        In February 2015, SAT issued a Public Notice Regarding Certain Corporate Income Tax Matters on Indirect Transfer of Properties by Non-Tax Resident Enterprises, or SAT Circular 7. SAT Circular 7 supersedes the rules with respect to the Indirect Transfer under SAT Circular 698, but does not touch upon the other provisions of SAT Circular 698, which remain in force. SAT Circular 7 has introduced a new tax regime that is significantly different from the previous one under SAT Circular 698. SAT Circular 7 extends its tax jurisdiction to not only Indirect Transfers set forth under SAT Circular 698 but also transactions involving transfer of other taxable assets through offshore transfer of a foreign intermediate holding company. In addition, SAT Circular 7 provides clearer criteria than SAT Circular 698 for assessment of reasonable commercial purposes and has introduced safe harbors for internal group restructurings and the purchase and sale of equity through a public securities market. SAT Circular 7 also brings challenges to both foreign transferor and transferee (or other person who is obligated to pay for the transfer) of taxable assets. Where a non-resident enterprise transfers taxable assets indirectly by disposing of the equity interests of an overseas holding company, which is an Indirect Transfer, the non-resident enterprise as either transferor or transferee, or the PRC entity that directly owns the taxable assets, may report such Indirect Transfer to the relevant tax authority. Using a "substance over form" principle, the PRC tax authority may disregard the existence of the overseas holding company if it lacks a reasonable commercial purpose and was established for the purpose of reducing, avoiding or deferring PRC tax. As a result, gains derived from such Indirect Transfer may be subject to PRC enterprise income tax, and the transferee or other person who is obligated to pay for the transfer is obligated to withhold the applicable taxes, currently at a rate of 10% for the transfer of equity interests in a PRC resident enterprise. Both the transferor and the transferee may be subject to penalties under PRC tax laws if the transferee fails to withhold the taxes and the transferor fails to pay the taxes.

        In October 2017, SAT issued an Announcement on Issues Relating to Withholding at Source of Income Tax of Non-resident Enterprises, or SAT Circular 37. Effective December 2017, SAT Circular 37, among others, repealed the Circular 698 and amended certain provisions in SAT Circular 7. According to SAT Circular 37, where the non-resident enterprise fails to declare the tax payable pursuant to Article 39 of the Enterprise Income Tax, the tax authority may order it to pay the tax due within required time limits, and the non-resident enterprise shall declare and pay the tax payable within such time limits specified by the tax authority. However, if the non-resident enterprise voluntarily declares and pays the tax payable before the tax authority orders it to do so within required time limits, it shall be deemed that such enterprise has paid the tax in time.

        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 and 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 Circular 7 and SAT Circular 37. For transfer of shares in our company by investors who are non-PRC resident enterprises, our PRC subsidiary may be requested to assist in the filing under the SAT circulars. As a result, we may be required to expend

valuable resources to comply with the SAT circulars 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.

The audit report included in our 2019 Annual Report is prepared by an auditor who is not inspected by the Public Company Accounting Oversight Board and, as such, you are deprived of the benefits of such inspection. In addition, various legislative and regulatory developments related to U.S.-listed China-based companies due to lack of PCAOB inspection and other developments may have a material adverse impact on our listing and trading in the U.S. and the trading prices of our ADSs.

        Our auditor is registered with the Public Company Accounting Oversight Board (United States), or the PCAOB. Pursuant to laws in the United States, the PCAOB has authority to conduct regular inspections over independent registered public accounting firms registered with the PCAOB to assess their compliance with the applicable professional standards. Our auditor is also located in China, a jurisdiction which does not allow the PCAOB to conduct inspections without the approval of the Chinese authorities. As a result, we understand that our auditor is not currently inspected by the PCAOB.

        In May 2013, the PCAOB announced that it had entered into a Memorandum of Understanding on Enforcement Cooperation with the CSRC and the PRC Ministry of Finance, which established a cooperative framework between the parties for the production and exchange of audit documents relevant to investigations undertaken by the PCAOB, the CSRC or the PRC Ministry of Finance in the United States and the PRC. The PCAOB continued to discuss with the CSRC and the PRC Ministry of Finance on joint inspections in the PRC of PCAOB-registered audit firms that provide auditing services to Chinese companies that trade on U.S. stock exchanges. On December 7, 2018, the SEC and the PCAOB issued a joint statement highlighting the continued challenges faced by the U.S. regulators in their oversight of financial statement audits of U.S.-listed companies with significant operations in China. On April 21, 2020, the SEC and the PCAOB issued another joint statement reiterating the greater risks of insufficient disclosures from companies in many emerging markets, including China, compared to those from U.S. domestic companies. In discussing the specific issues related to these risks, the statement again highlighted the PCAOB's inability to inspect audit work and practices of accounting firms in China with respect to U.S. reporting companies. On June 4, 2020, the U.S. President issued a memorandum ordering the President's Working Group on Financial Markets, or the PWG, to submit a report to the President within 60 days of the memorandum that includes recommendations for actions that can be taken by the executive branch and by the SEC or the PCAOB on Chinese companies listed on U.S. stock exchanges and their audit firms. On August 6, 2020, the PWG released the report. In particular, with respect to jurisdictions that do not grant the PCAOB sufficient access to fulfill its statutory mandate, or NCJs, the PWG recommended that enhanced listing standards be applied to companies from NCJs for seeking initial listing and remaining listed on U.S. stock exchanges. Under the enhanced listing standards, if the PCAOB does not have access to work papers of the principal audit firm located in a NCJ for the audit of a U.S.-listed company as a result of governmental restrictions, the U.S.-listed company may satisfy this standard by providing a co-audit from an audit firm with comparable resources and experience where the PCAOB determines that it has sufficient access to the firm's audit work papers and practices to inspect the co-audit. The report recommended a transition period until January 1, 2022 before the new listing standards apply to companies already listed on U.S. stock exchanges. Under the PWG recommendations, if we fail to meet the enhanced listing standards before January 1, 2022, we could face de-listing from the Nasdaq Global Select Market, deregistration from the SEC and/or other risks, which may materially and adversely affect, or effectively terminate, our ADS trading in the United States. There were recent media reports about the SEC's proposed rulemaking in this regard. It is uncertain whether the PWG recommendations will be adopted, in whole or in part, and the impact of any new rule on us cannot be estimated at this time.

        This lack of the PCAOB inspections in China prevents the PCAOB from fully evaluating audits and quality control procedures of our independent registered public accounting firm. As a result, we and investors in our ordinary shares are deprived of the benefits of such PCAOB inspections. The inability of the PCAOB to conduct inspections of auditors in China makes it more difficult to evaluate the effectiveness of our independent registered public accounting firm's audit procedures or quality control procedures as compared to auditors outside of China that are subject to the PCAOB inspections, which could cause investors and potential investors in our ADSs to lose confidence in our audit procedures and reported financial information and the quality of our financial statements.

        As part of a continued regulatory focus in the United States on access to audit and other information currently protected by national law, in particular China's, in June 2019, a bipartisan group of lawmakers introduced bills in both houses of the U.S. Congress, which if passed, would require the SEC to maintain a list of issuers for which the PCAOB is not able to inspect or investigate auditor reports issued by foreign public accounting firms. The proposed Ensuring Quality Information and Transparency for Abroad-Based Listings on our Exchanges (EQUITABLE) Act prescribes increased disclosure requirements for these issuers and, beginning in 2025, the delisting from U.S. stock exchanges of issuers included on the SEC's list for three consecutive years. On May 20, 2020, the U.S. Senate passed S. 945, the Holding Foreign Companies Accountable Act, or the Kennedy Bill. On July 21, 2020, the U.S. House of Representatives approved its version of the National Defense Authorization Act for Fiscal Year 2021, which contains provisions comparable to the Kennedy Bill. If either of these bills is enacted into law, it would amend the Sarbanes-Oxley Act of 2002 to direct the SEC to prohibit securities of any registrant from being listed on any of the U.S. securities exchanges or traded "over-the-counter" if the auditor of the registrant's financial statements is not subject to PCAOB inspection for three consecutive years after the law becomes effective. Enactment of any of such legislations or other efforts to increase U.S. regulatory access to audit information could cause investor uncertainty for affected issuers, including us, the market price of our ADSs could be adversely affected, and we could be delisted if we are unable to cure the situation to meet the PCAOB inspection requirement in time. It is unclear if and when any of such proposed legislations will be enacted.

Proceedings instituted by the SEC against Chinese affiliates of the "big four" 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.

        Starting in 2011, the Chinese affiliates of the "big four" accounting firms, including our independent registered public accounting firm, were affected by a conflict between U.S. and Chinese law. Specifically, for certain U.S.-listed companies operating and audited in mainland China, the SEC and the PCAOB sought to obtain from the Chinese firms access to their audit work papers and related documents. The firms were, however, advised and directed that under Chinese law, they could not respond directly to the U.S. regulators on those requests, and that requests by foreign regulators for access to such papers in China had to be channeled through the CSRC.

        In late 2012, this impasse led the SEC to commence administrative proceedings under Rule 102 (e) of its Rules of Practice and also under the Sarbanes-Oxley Act of 2002 against the Chinese accounting firms, including our independent registered public accounting firm. A first instance trial of the proceedings in July 2013 in the SEC's internal administrative court resulted in an adverse judgment against the firms. The administrative law judge proposed penalties on the firms including a temporary suspension of their right to practice before the SEC, although that proposed penalty did not take effect pending review by the Commissioners of the SEC. On February 6, 2015, before a review by the Commissioner had taken place, the firms reached a settlement with the SEC. Under the settlement, the SEC accepts that future requests by the SEC for the production of documents will normally be made to the CSRC. The firms will receive matching Section 106 requests, and are required to abide by

S-59

Table of Contents

a detailed set of procedures with respect to such requests, which in substance require them to facilitate production via the CSRC. If they fail to meet specified criteria, the SEC retains authority to impose a variety of additional remedial measures on the firms depending on the nature of the failure. Remedies for any future noncompliance could include, as appropriate, an automatic six-month bar on a single firm's performance of certain audit work, commencement of a new proceeding against a firm, or in extreme cases the resumption of the current proceeding against all four firms. If additional remedial measures are imposed on the Chinese affiliates of the "big four" accounting firms, including our independent registered public accounting firm, in administrative proceedings brought by the SEC alleging the firms' failure to meet specific criteria set by the SEC with respect to requests for the production of documents, we could be unable to timely file future financial statements in compliance with the requirements of the Exchange Act.

        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, including possible delisting. Moreover, any negative news about any such future proceedings against these audit firms may cause investor uncertainty regarding China-based, U.S.-listed companies and the market price of our ADSs may be adversely affected.

        If our independent registered public accounting firm was denied, even 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 not to be in compliance with the requirements of the Exchange Act. Such a determination could ultimately lead to the delisting of our ADSs from the Nasdaq Global Select Market or deregistration from the SEC, or both, which would substantially reduce or effectively terminate the trading of our ADSs in the United States.

Risks Related to this Offering, Our Class A Ordinary Shares and Our ADSs

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

        Since our ADSs became listed on the Nasdaq Global Select Market on July 26, 2018, the trading price of our ADSs has ranged from US$16.53 to US$155.61 per ADS. The trading price of our ADSs may 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 business operations located mainly in China that have listed their securities in the United States. The trading performances of other Chinese companies' securities, including internet and e-commerce companies, may affect the attitudes of investors toward Chinese companies listed in the United States, which consequently may impact the trading performance of our ADSs, regardless of our actual operating performance. In addition, any negative news or perceptions about inadequate corporate governance practices or fraudulent accounting, corporate structure or matters of other Chinese companies may also negatively affect the attitudes of investors towards Chinese companies in general, including us, regardless of our conduct. In addition, securities markets may from time to time experience significant price and volume fluctuations that are not related to our operating performance, such as the recent large decline in share prices in the United States, which may have a material and adverse effect on the trading price of our ADSs. 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:

•

variations in our revenues, earnings and cash flow;



•

announcements of new investments, acquisitions, strategic partnerships or joint ventures by us or our competitors;

S-60

Table of Contents

•

announcements of new offerings, solutions and expansions by us or our competitors;



•

changes in financial estimates by securities analysts;



•

detrimental adverse publicity about us, our brand, our services or our industry;



•

additions or departures of key personnel;



•

release of lock-up or other transfer restrictions on our outstanding equity securities or sales of additional equity securities;



•

convertible arbitrage strategy employed by certain investors in the convertible notes offered in the concurrent Convertible Notes Offering and/or the 2024 Notes, including related short selling of our ADS; and



•

potential litigation or regulatory investigations.

        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, such as the putative class action lawsuits we disclosed in the "Item 8. Financial Information—A. Consolidated Statements and Other Financial Information—Legal Proceedings" of our 2019 Annual Report. These putative class action suits could divert a significant amount of our management's attention and other resources from our business and operations and require us to incur significant expenses to defend the suits, which could harm our results of operations. Moreover, these class action suits, 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 or indemnification claims, which could have a material adverse effect on our financial condition and results of operations.

We may need additional capital, and the sale of additional ADSs or other equity or equity-linked securities could result in additional dilution to our shareholders, and the incurrence of additional indebtedness could increase our debt service obligations.

        We may require additional cash resources due to changes in business conditions, strategic acquisitions or other future developments. If these resources are insufficient to satisfy our cash requirements, we may seek to sell additional equity or debt securities or obtain additional credit facilities. The sale of additional equity and equity-linked securities, as well as any future issuance of Chinese Depositary Receipts, or CDRs, could result in additional dilution to our shareholders and ADS holders and adversely impact the market price of our ADSs. The incurrence of indebtedness would result in increased debt service obligations and could result in operating and financing 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.

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

        We have a dual-class share structure such that our ordinary shares consist of Class A ordinary shares and Class B ordinary shares. In respect of matters requiring the votes of shareholders, holders of Class A ordinary shares will be entitled to one vote per share, while holders of Class B ordinary shares will be entitled to ten votes per share based on our dual-class share structure. Each Class B ordinary share is convertible into one Class A ordinary share at any time at the option of the holder thereof, while Class A ordinary shares are not convertible into Class B ordinary shares under any circumstances.

Table of Contents

Upon any sale, transfer, assignment or disposition of any Class B ordinary shares by a holder thereof to any person other than Mr. Zheng Huang or any entity which is not ultimately controlled by Mr. Zheng Huang, such Class B ordinary shares shall be automatically and immediately converted into the same number of Class A ordinary shares.

        As of the date of this prospectus supplement, our founder and chairman of the board of directors, Mr. Zheng Huang, beneficially owns all of our issued Class B ordinary shares. As of September 30, 2020, these Class B ordinary shares constituted approximately 29.4% of our total issued and outstanding share capital and 80.7% of the aggregate voting power of our total issued and outstanding share capital due to the disparate voting powers associated with our dual-class share structure. As a result of the dual-class share structure and the concentration of ownership, holders of Class B ordinary shares have considerable influence over matters such as decisions regarding mergers, consolidations and the sale of all or substantially all of our assets, election of directors and other significant corporate actions. Such holders may take actions that are not in the best interest of us or our other shareholders. This concentration of ownership may discourage, delay or prevent a change in control of our company, which could have the effect of depriving our other shareholders of the opportunity to receive a premium for their shares as part of a sale of our company and may reduce the price of our ADSs. This concentrated control will limit your ability to influence corporate matters and could discourage others from pursuing any potential merger, takeover or other change of control transactions that holders of Class A ordinary shares and ADSs may view as beneficial.

The dual-class share structure of our ordinary shares may adversely affect the trading market for our ADSs.

        S&P Dow Jones and FTSE Russell have recently announced changes to their eligibility criteria for inclusion of shares of public companies on certain indices, including the S&P 500, to exclude companies with multiple classes of shares and companies whose public shareholders hold no more than 5% of total voting power from being added to such indices. In addition, several shareholder advisory firms have announced their opposition to the use of multiple class structures. As a result, the dual class structure of our ordinary shares may prevent the inclusion of our ADSs representing Class A ordinary shares in such indices and may cause shareholder advisory firms to publish negative commentary about our corporate governance practices or otherwise seek to cause us to change our capital structure. Any such exclusion from indices could result in a less active trading market for our ADSs. Any actions or publications by shareholder advisory firms critical of our corporate governance practices or capital structure could also adversely affect the value of our ADSs.

Our management has broad discretion over the use of proceeds from the offering and our concurrent Convertible Notes Offering and may not apply the proceeds in ways that increase the value of your investment.

        Our management will have significant discretion in applying the net proceeds that we receive from this offering and the concurrent Convertible Notes Offering. Although we intend to use the net proceeds from these offerings as described in "Use of Proceeds," our management retains significant discretion with respect to the use of proceeds. Our management might not apply the net proceeds from these offerings in ways that increase the value of your investment. You may not have the opportunity, as part of your investment decision, to assess whether proceeds are being used appropriately. The net proceeds from these offerings may be used in a manner that does not generate favorable returns.

Provisions of our convertible notes being offered concurrently and the 2024 Notes could discourage an acquisition of us by a third party.

        Concurrently with this offering, we are offering US$1,750,000,000 aggregate principal amount of convertible senior notes due 2025. In September 2019, we completed an offering of US$1 billion in aggregate principal amount of the 2024 Notes. Certain provisions of our convertible notes and the 2024 Notes could make it more difficult or more expensive for a third party to acquire us. The indenture for

Table of Contents

our convertible notes defines a "fundamental change" to include, among other things: (i) any person or group becoming a beneficial owner of our company through gaining more than 50% voting power of our ordinary share capital (other than, in particular, a permitted holder as defined in the terms of the notes) or more than 50% of our outstanding Class A ordinary shares; (ii) any recapitalization, reclassification or change of our Class A ordinary shares or ADSs as a result of which these securities would be converted into, or exchanged for, stock, other securities, other property or assets or any share exchange, consolidation or merger or similar transaction pursuant to which our Class A ordinary shares or ADSs will be converted into cash, securities or other property or any sale, lease or other transfer in one transaction or series of transaction of all or substantially all our consolidated assets, to any person other than one of our subsidiaries or consolidated affiliated entities; (iii) the approval by our shareholders of any plan or proposal for the liquidation or dissolution of our company; (iv) our ADSs ceasing to be listed or quoted on any of The Nasdaq Global Select Market, The Nasdaq Global Select Market or The New York Stock Exchange (or any of their respective successors) and none of the ADSs, Class A ordinary shares, other common equity and ADSs in respect of reference property is listed or quoted on one of The Nasdaq Global Select Market, The Nasdaq Global Select Market or The New York Stock Exchange (or any of their respective successors) within one trading day of such cessation; or (v) any change in or amendment to the laws, regulations and rules in the PRC that prohibits us from operating substantially all of our business operations and prevents us from continuing to derive substantially all of the economic benefits from our business operations. Upon the occurrence of a fundamental change, holders of the convertible notes will have the right, at their option, to require us to repurchase all of their notes or any portion of the principal amount of such notes in integral multiples of US$1,000. In the event of a make-whole fundamental change (as defined in the terms of the convertible notes), we may also be required to issue additional ADSs upon conversion of our convertible notes in connection with such make-whole fundamental change. The indenture governing the 2024 Notes contains similar provisions.

Conversion of the 2024 Notes or concurrently offered convertible notes may dilute the ownership interest of the existing shareholders, including holders who had previously converted their convertible notes and/or the 2024 Notes.

        The conversion of some or all of the convertible notes being offered in the concurrent Convertible Notes Offering and/or the 2024 Notes, will dilute the ownership interests of existing shareholders and existing holders of our ADSs. Any sales in the public market of the ADSs, if any, issuable upon such conversion may increase the opportunities to create short positions with respect to the ADSs, which could adversely affect prevailing market prices of our ADSs. In addition, the existence of the convertible notes and/or the 2024 Notes may encourage short selling by market participants because the conversion of the convertible notes and/or the 2024 Notes could depress the price of our ADSs. The price of our ADSs could be affected by possible sales of our ADSs by investors who view the convertible notes and/or the 2024 Notes as a more attractive means of equity participation in us and by hedging or arbitrage trading activity, which we expect to occur involving our ADSs.

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.

Techniques employed by short sellers and/or the convertible bond arbitrage strategy employed by investors in the concurrent Convertible Notes Offering and the 2024 Notes may drive down the market price of the ADSs.

        Short selling is the practice of selling securities that a seller does not own but rather has borrowed from a third party with the intention of buying identical securities back at a later date to return to the lender. Short sellers hope to profit from a decline in the value of the securities between the sale of the borrowed securities and the purchase of the replacement shares, as short sellers expect to pay less in that purchase than they received in the sale. As it is in short sellers' interest for the price of the security to decline, many short sellers publish, or arrange for the publication of, negative opinions and allegations regarding the relevant issuer and its business prospects in order to create negative market momentum and generate profits for themselves after selling a security short. These short attacks have, in the past, led to selling of shares in the market.

        We have been the subject of short selling, and it is not clear what long-term effect such negative publicity could have on us. We may also be subject to short seller attacks from time to time in the future. If we were to become the subject of any unfavorable allegations, whether such allegations are proven to be true or untrue, we may have to expend a significant amount of resources to investigate such allegations and/or defend ourselves. While we would strongly defend against any such short seller attacks, we may be constrained in the manner in which we can proceed against the relevant short sellers by principles of freedom of speech, applicable state law or issues of commercial confidentiality. Such a situation could be costly and time-consuming, and could divert management's attention from the day-to-day operations of our company. Even if such allegations are ultimately proven to be groundless, allegations against us could severely impact the market price of our ADSs and our business operations.

        Furthermore, we expect that many investors in, and potential purchasers of, the convertible notes that we are offering in the concurrent Convertible Notes Offering will employ (or seek to employ), and many investors in the 2024 Notes will continue to employ, a convertible arbitrage strategy with respect to the convertible notes and the 2024 Notes, respectively. Investors in such instruments as the convertible notes and the 2024 Notes would typically implement such a strategy by selling short the ADSs underlying the relevant notes and dynamically adjusting their short position while continuing to hold the relevant notes. Investors in the relevant notes may also implement this type of strategy by entering into swaps on the ADSs in lieu of or in addition to short selling the ADSs. The market activity related to such convertible arbitrage strategy could adversely affect prevailing trading prices of the ADSs.

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 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. 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.

Because we do not expect to pay dividends in the foreseeable future, you must rely on a 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 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. In addition, our shareholders may by ordinary resolution declare a dividend, but no dividend may exceed the amount recommended by our directors. Under

S-64

---

Table of Contents

Cayman Islands law, a Cayman Islands 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 the company being unable to pay its debts as they fall due in the ordinary course of business. Even if our board of directors decides to declare and pay dividends, the timing, amount and form of future dividends, if any, will depend on 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 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.

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.

        Our currently effective 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. Our dual-class voting structure gives disproportionate voting power to holders of the Class B ordinary shares. 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 incorporated under the laws of the Cayman Islands. Our corporate affairs are governed by our memorandum and articles of association, the Companies Law (2020 Revision) of the Cayman Islands and the common law of the Cayman Islands. The rights of shareholders to take action against our directors, actions by our minority shareholders and the fiduciary duties 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 duties 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 (except the memorandum and articles of association) or to

S-65

---

Table of Contents

obtain copies of lists of shareholders of these companies. Our directors have discretion under our currently effective 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, our 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.

It may be difficult for overseas regulators to conduct investigations or collect evidence within China.

        Shareholder claims or regulatory investigation that are common in the United States generally are difficult to pursue as a matter of law or practicality in China. For example, in China, there are significant legal and other obstacles to providing information needed for regulatory investigations or litigation initiated outside China. Although the authorities in China may establish a regulatory cooperation mechanism with the securities regulatory authorities of another country or region to implement cross-border supervision and administration, such cooperation with the securities regulatory authorities in the Unities States may not be efficient in the absence of mutual and practical cooperation mechanism. Furthermore, according to Article 177 of the PRC Securities Law, or Article 177, which became effective in March 2020, no overseas securities regulator is allowed to directly conduct investigations or evidence collection activities within the territory of the PRC. While detailed interpretation of or implementation rules under Article 177 have yet to be promulgated, the inability for an overseas securities regulator to directly conduct investigations or evidence collection activities within China may further increase difficulties faced by you in protecting your interests.

ADSs holders may not be entitled to a jury trial with respect to claims arising under the deposit agreement, which could result in less favorable outcomes to the plaintiff(s) in any such action.

        The deposit agreement governing the ADSs representing our ordinary shares provide that, subject to the depositary's right to require a claim to be submitted to arbitration, the federal or state courts in the City of New York have exclusive jurisdiction to hear and determine claims arising under the deposit agreement and in that regard, to the fullest extent permitted by law, ADS holders waive the right to a jury trial of any claim they may have against us or the depositary arising out of or relating to our shares, the ADSs or the deposit agreement, including any claim under the U.S. federal securities laws.

        If we or the depositary opposed a jury trial demand based on the waiver, the court would determine whether the waiver was enforceable based on the facts and circumstances of that case in accordance with the applicable U.S. state and federal law. To our knowledge, the enforceability of a contractual pre-dispute jury trial waiver in connection with claims arising under the U.S. federal securities laws has not been finally adjudicated by the United States Supreme Court. However, based on past court decisions, we believe that a contractual pre-dispute jury trial waiver provision is generally enforceable, including under the laws of the State of New York, which govern the deposit agreement. In determining whether to enforce a contractual pre-dispute jury trial waiver provision, courts will generally consider whether a party knowingly, intelligently and voluntarily waived the right to a jury trial. We believe that this is the case with respect to the deposit agreement and the ADSs. It is advisable that you consult legal counsel regarding the jury waiver provision under the deposit agreement before investing in the ADSs.

        If you or any other holders or beneficial owners of ADSs bring a claim against us or the depositary in connection with matters arising under the deposit agreement or the ADSs, including claims under U.S. federal securities laws, you or such other holder or beneficial owner may not be entitled to a jury

S-66

Table of Contents

trial with respect to such claims, which may have the effect of limiting and discouraging lawsuits against us and/or the depositary. If a lawsuit is brought against us and/or the depositary under the deposit agreement, it may be heard only by a judge or justice of the applicable trial court, which would be conducted according to different civil procedures and may result in different outcomes than a trial by jury would have had, including results that could be less favorable to the plaintiff(s) in any such action.

        Nevertheless, if this jury trial waiver provision is not enforced, to the extent a court action proceeds, it would proceed under the terms of the deposit agreement with a jury trial. No condition, stipulation or provision of the deposit agreement or ADSs serves as a waiver by any holder or beneficial owner of ADSs or by us or the depositary of compliance with the U.S. federal securities laws and the rules and regulations promulgated thereunder.

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

        We are a Cayman Islands exempted company and substantially all of our assets are located outside of the United States. Substantially all of our current operations are conducted in China. In addition, most 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.

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 Class A 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. As an ADS holder, you will only be able to exercise the voting rights carried by the underlying Class A ordinary shares represented by your ADSs indirectly by giving voting instructions to the depositary in accordance with the provisions of the deposit agreement. Under the deposit agreement, you may vote only 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 underlying Class A ordinary shares represented by 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 Class A ordinary shares represented by your ADSs 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 Class A ordinary shares represented by your ADSs unless you withdraw such 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 underlying Class A ordinary shares represented by 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 currently effective memorandum and articles of association, 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 underlying Class A ordinary shares represented by 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 have agreed to give the depositary notice of shareholder meetings sufficiently in advance of such meetings. Nevertheless, 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 Class A 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. The deposit agreement provide that if the depositary does not timely receive voting instructions from the ADS holders and if voting is by poll, then such holder shall be deemed, and the depositary shall deem such holder, to have instructed the depositary to give a discretionary proxy to a person designated by us to vote the underlying Class A ordinary shares represented by the relevant ADSs, with certain limited exceptions. This means that you may not be able to exercise your right to direct how the underlying Class A ordinary shares represented by your ADSs are voted and you may have no legal remedy if the underlying Class A ordinary shares represented your ADSs are not voted as you requested.

You may experience dilution of your holdings due to the inability to participate in future 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.

You may be subject to limitations on the transfer of your ADSs.

        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 it 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.

Your investment in our ADSs may be impacted if we are encouraged to issue CDRs in the future.

        The Chinese central government is currently proposing new rules that would allow Chinese technology companies listed outside China to list on the mainland stock market through the creation of CDRs. Once the CDR mechanism is in place, we might consider and be encouraged by the evolving Chinese governmental policies to issue CDRs and allow investors to trade our CDRs on Chinese stock exchanges. However, there are uncertainties as to whether a pursuit of CDRs in China would bring positive or negative impact on your investment in our ADSs.

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

        As a public company, we incur significant accounting, legal and other expenses. The Sarbanes-Oxley Act, as well as rules subsequently implemented by the SEC and Nasdaq, have detailed

S-68

Table of Contents

requirements concerning corporate governance practices of public companies, including Section 404 of the Sarbanes-Oxley Act relating to internal controls over financial reporting. 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 and the other rules and regulations of the SEC. For example, as a result of becoming a public company, we need to adopt policies regarding internal controls and disclosure controls and procedures. In addition, we incur additional costs associated with our public company reporting requirements. 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 an exempted 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 Nasdaq corporate governance listing standards; these practices may afford less protection to shareholders than they would enjoy if we complied fully with the Nasdaq corporate governance listing standards.

        As a Cayman Islands exempted company listed on the Nasdaq Global Select Market, we are subject to the Nasdaq Stock Market corporate governance listing standards. However, Nasdaq Stock Market 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 the Nasdaq Stock Market corporate governance listing standards. We rely on home country practice exemption with respect to the requirement for annual shareholders meetings and did not hold an annual shareholders meeting in 2019. We may also opt to rely on additional home country practice exemptions in the future. As a result, our shareholders may be afforded less protection than they would otherwise enjoy under the Nasdaq Stock Market corporate governance listing standards applicable to U.S. domestic issuers.

There can be no assurance that we will not be classified as a passive foreign investment company, or PFIC, for U.S. federal income tax purposes for any taxable year, which could subject U.S. investors in our ADSs or Class A ordinary shares to significant adverse U.S. income tax consequences.

        We will be a "passive foreign investment company," or "PFIC," if, in any particular taxable year, either (a) 75% or more of our gross income for such year consists of certain types of "passive" income or (b) 50% or more of the value of our assets (generally determined on the basis of a quarterly average) during such year produce 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 VIE (including its subsidiaries) as being owned by us for U.S. federal income tax purposes, not only because we exercise effective control over the operation of such entity but also because we are entitled to substantially all of its economic benefits, and, as a result, we consolidate its results of operations in our consolidated financial statements. Assuming that we are the owner of our VIE (including its subsidiaries) for U.S. federal income tax purposes, we do not believe that we were a PFIC for the taxable year ended December 31, 2019 and based upon our current and expected income and assets, including goodwill, and the current and projected value of our ADSs, we do not expect to be a PFIC in the current taxable year or for the foreseeable future.

        While we do not believe that we were a PFIC for the taxable year ended December 31, 2019 and we do not expect to become a PFIC, because the value of our assets for purposes of the asset test may be determined by reference to the market price of our ADSs, fluctuations in the market price of our ADSs may cause us to become a PFIC for the current or subsequent taxable years. The determination of whether we will be or become a PFIC will also depend, in part, on the composition of our income and assets, which may be affected by how, and how quickly, we use our liquid assets and the cash raised in this offering. If it were determined that we do not own the stock of our VIE for U.S. federal income tax purposes, our risk of being a PFIC may substantially increase. Because PFIC status is a

Table of Contents

factual determination made annually after the close of each taxable year, there can be no assurance that we will not be a PFIC for the current taxable year or any future taxable year.

        If we are a PFIC in any taxable year, a U.S. holder (as defined in "Item 10. Additional Information—E. Taxation—U.S. Federal Income Tax Considerations") may incur significantly increased U.S. income tax on gain recognized on the sale or other disposition of the ADSs or Class A ordinary shares and on the receipt of distributions on the ADSs or Class A ordinary shares to the extent such gain or distribution is treated as an "excess distribution" under the 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 Class A 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 Class A ordinary shares.

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

        You should read the following discussion and analysis of our financial condition and results of operations in conjunction with our audited consolidated financial statements for the years ended December 31, 2017, 2018 and 2019 and as of December 31, 2018 and 2019, and related notes, included in our 2019 Annual Report, information under "Item 5. Operating and Financial Review and Prospects" of our 2019 Annual Report and our unaudited interim condensed consolidated financial statements for the nine months ended September 30, 2019 and 2020 and as of September 30, 2020 and related notes included in our current report on Form 6-K furnished to the SEC on November 16, 2020, including all exhibits thereto, which are incorporated into the accompanying prospectus by reference. This discussion may contain forward-looking statements based upon current expectations that involve risks and uncertainties. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of various factors, including those set forth under "Risk Factors" or in other parts of this prospectus supplement.

        The following table sets forth a summary of our consolidated results of operations for the periods presented, both in absolute amount and as a percentage of our revenues for the periods presented. This information should be read together with, and is qualified in its entirety by reference to, our audited consolidated financial statements for the years ended December 31, 2017, 2018 and 2019 and as of December 31, 2018 and 2019, and related notes, included in our 2019 Annual Report, information under "Item 5. Operating and Financial Review and Prospects" of our 2019 Annual Report and our unaudited interim condensed consolidated financial statements for the nine months ended September 30, 2019 and 2020 and as of September 30, 2020 and related notes included in our current report on Form 6-K furnished to the SEC on November 16, 2020, including all exhibits thereto, which are incorporated into the accompanying prospectus by reference. The results of operations in any period are not necessarily indicative of our future trends.

        As disclosed in "Selected Consolidated Financial and Operating Data," due to the loss of the EGC status, we adopted ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), as amended, effective January 1, 2018 using the modified retrospective approach. There were no changes made to our revenue recognition policy as a result of the adoption of Topic 606. We also changed the classification and presentation of restricted cash on the consolidated statements of cash flows for each of the three years in the period ended December 31, 2018 due to the adoption of ASU No. 2016-18, Statement of Cash Flows: Restricted Cash. We adopted ASU No. 2016-02: Leases on January 1, 2019 using the modified retrospective transition method. ROU assets and lease liabilities (including current and non-current) for operating leases are presented on the face of the consolidated balance sheet as of December 31, 2019, while the consolidated balance sheet data for the years ended December 31, 2016, 2017 and 2018 have been prepared in accordance with ASC Topic 840, Accounting for Leases. We adopted ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, effective January 1, 2020 using the modified retrospective transition method. Upon adoption, we changed the impairment model to utilize a forward-looking current

Nine months ended September 30, 2020 compared to nine months ended September 30, 2019

Revenues

        Our revenues increased by 70.3% from RMB19,349.2 million in the nine months ended September 30, 2019 to RMB32,944.2 million (US$4,852.2 million) in the nine months ended September 30, 2020. Online marketing services and other revenues increased by 71.8% from RMB17,126.9 million in the nine months ended September 30, 2019 to RMB29,424.6 million (US$4,333.8 million) in the nine months ended September 30, 2020. This increase was primarily

S-72

---

Table of Contents

attributable to our stronger brand and market position as a result of our branding campaigns, more active merchants offering greater breadth of products, better marketing products and tools for merchants, and the significant increase in the number of our active buyers and annual spending per active buyer. Revenues from transaction services increased 58.4% from RMB2,222.2 million in the nine months ended September 30, 2019 to RMB3,519.5 million (US$518.4 million) in the nine months ended September 30, 2020, primarily due to the increase in GMV.

Costs of revenues

        Our costs of revenues increased by 80.2% from RMB4,301.3 million in the nine months ended September 30, 2019 to RMB7,752.5 million (US$1,141.8 million) in the nine months ended September 30, 2020, primarily due to increases in bandwidths and server costs and other expenses directly attributable to the online marketing services and other revenues. The increase in bandwidths and server costs from RMB1,145.7 million in the nine months ended September 30, 2019 to RMB2,487.1 million (US$366.3 million) in the nine months ended September 30, 2020 was due to the increase in server capacity to keep pace with the growth of our online marketplace services. The increase in other expenses directly attributable to the online marketing services and other revenues was primarily due to the higher costs of call center and merchant support services.

Gross profit

        As a result of the foregoing, our gross profit increased to RMB25,191.6 million (US$3,710.3 million) in the nine months ended September 30, 2020, from RMB15,047.8 million in the nine months ended September 30, 2019. Our gross margin for the nine months ended September 30, 2020 was 76.5% as compared to 77.8% for the same period last year. The changes in our gross profit and our gross margin reflected the continued growth of our online marketplace model, offset by the disruptions caused by the pandemic during the first three months of 2020 and increase in our server costs.

Operating expenses

        Our total operating expenses increased by 51.6% from RMB21,450.7 million in the nine months ended September 30, 2019 to RMB32,524.2 million (US$4,790.3 million) in the nine months ended September 30, 2020 primarily due to the increases in sales and marketing expenses and research and development expenses.

        Sales and marketing expenses.    Our sales and marketing expenses increased by 47.9% from RMB17,901.7 million in the nine months ended September 30, 2019 to RMB26,482.1 million (US$3,900.4 million) in the nine months ended September 30, 2020, primarily attributable to increases of RMB8,227.4 million (US$1,211.8 million) in advertising expenses and promotion and coupon expenses. The increase in advertising expenses and promotion and coupon expenses were focused on building our brand awareness and driving user growth and engagement on our platform.

        General and administrative expenses.    Our general and administrative expenses increased from RMB951.0 million in the nine months ended September 30, 2019 to RMB1,101.7 million (US$162.3 million) in the nine months ended September 30, 2020. The increase was primarily attributable to an increase in headcount for administrative personnel, offset by not incurring certain expenses relating to our poverty alleviation initiatives in 2019.

        Research and development expenses.    Our research and development expenses increased by 90.2% from RMB2,598.0 million in the nine months ended September 30, 2019 to RMB4,940.4 million (US$727.6 million) in the nine months ended September 30, 2020, primarily due to an increase of RMB1,677.2 million in staff costs, and an increase of RMB609.2 million in R&D-related cloud services

expenses. The increase in staff costs was primarily attributable to the increase in headcount and the recruitment of more experienced research and development personnel to execute our technology-related strategies of improving our platform.

Operating loss

        As a result of the foregoing, we incurred operating loss of RMB6,402.9 million and RMB7,332.6 million (US$1,080.0 million) in the nine months ended September 30, 2019 and 2020, respectively.

Other income/(expenses)

        Interest and investment gain, net.    Net interest and investment gain mainly represents interest earned on demand deposits, time deposits and wealth management products in financial institutions, as well as other long-term investments. We had net interest and investment gain of RMB1,069.3 million and RMB1,784.0 million (US$262.8 million) in the nine months ended September 30, 2019 and 2020, respectively. The increase was primarily attributable to the increase of our short-term investments and cash balance.

        Interest expense.    We had interest expense of RMB479.2 million (US$70.6 million) in the nine months ended September 30, 2020, compared to interest expense of RMB6.2 million in the nine months ended September 30, 2019, primarily due to the increase in interest expenses of RMB427.7 million related to the 2024 Notes' amortization to face value.

        Foreign exchange gain.    We had foreign exchange gain of RMB76.2 million (US$11.2 million) in the nine months ended September 30, 2020, compared to foreign exchange gain of RMB76.4 million in the nine months ended September 30, 2019, primarily due to the fluctuations of the exchange rates of Renminbi against the U.S. dollar.

        Other income, net.    We had other net income of RMB112.6 million (US$16.6 million) in the nine months ended September 30, 2020, compared to other net income of RMB55.6 million in the nine months ended September 30, 2019, primarily due to the increase of government grants, partially offset by the increase of our donation.

Income tax expenses

        We recorded nil in income tax expenses in the nine months ended September 30, 2019 and 2020.

Share of results of equity investees

        We had share of results of equity investees in gain of RMB35.6 million (US$5.2 million) in the nine months ended September 30, 2020, compared to a RMB8.2 million share of loss in the nine months ended September 30, 2019.

Net loss

        As a result of the foregoing, we incurred net loss of RMB5,803.4 million (US$854.7 million) in the nine months ended September 30, 2020, compared to net loss of RMB5,216.0 million in the nine months ended September 30, 2019.

Cash Flows and Working Capital

        As of September 30, 2020, our cash and cash equivalents were RMB5,715.7 million (US$841.8 million). Our cash and cash equivalents primarily consist of cash at banks. As of the same date, we had restricted cash of RMB38,813.1 million (US$5,716.5 million), mainly representing cash

received from buyers and reserved in a bank supervised account for payments to merchants. Our short-term investments, comprising primarily of time deposits and wealth management products, were RMB39,859.1 million (US$5,870.6 million) as of September 30, 2020.

Operating activities

        Net cash generated from operating activities in the nine months ended September 30, 2020 was RMB13,250.1 million (US$1,951.5 million), as compared to net loss of RMB5,803.4 million (US$854.7 million) in the same period. The difference was primarily due to an increase of RMB10,383.2 million (US$1,529.3 million) in payable to merchants, an increase of RMB2,733.6 million (US$402.6 million) in merchant deposits, an increase of RMB2,027.0 million (US$298.5 million) in accrued expenses and other liabilities, and an increase of RMB1,795.9 million (US$264.5 million) in amounts due to related parties, and a decrease of RMB520.0 million (US$76.6 million) in receivables from online payment platforms, partially offset by an increase of RMB1,083.6 million (US$159.6 million) in amounts due from related parties and an increase of RMB706.3 million (US$104.0 million) in prepayments and other current assets. The increase in payables to merchants, merchant deposits and accrued expenses and other liabilities were attributable to our business expansion and the increased number of merchants on our platform. The principal non-cash items affecting the difference between our net loss and our net cash generated from operating activities in the nine months ended September 30, 2020 included RMB2,679.8 million (US$394.7 million) in share-based compensation expenses.

        Net cash generated from operating activities in the nine months ended September 30, 2019 was RMB5,223.0 million, as compared to net loss of RMB5,216.0 million in the same period. The difference was primarily due to an increase of RMB2,543.7 million in payables to merchants, an increase of RMB2,465.9 million in merchant deposits, an increase of RMB1,977.5 million in accrued expenses and other liabilities, and an increase of RMB1,607.5 million in amounts due to related parties, partially offset by an increase of RMB276.9 million in receivables from online payment platforms and an increase of RMB234.5 million in amounts due from related parties. The increase in payables to merchants, merchant deposits and accrued expenses and other liabilities were attributable to our business expansion and the increased number of merchants on our platform. The principal non-cash items affecting the difference between our net loss and our net cash generated from operating activities in the nine months ended September 30, 2019 included RMB1,759.0 million in share-based compensation expenses.

Investing activities

        Net cash used in investing activities in the nine months ended September 30, 2020 was RMB11,735.1 million (US$1,728.4 million), primarily due to purchase of short-term investments of RMB44,110.8 million (US$6,496.8 million), partially offset by proceeds from sales of short-term investments of RMB39,042.0 million (US$5,750.3 million).

        Net cash used in investing activities in the nine months ended September 30, 2019 was RMB16,857.8 million, primarily due to purchase of short-term investments of RMB31,036.9 million, partially offset by proceeds from sales of short-term investments of RMB14,371.8 million.

Financing activities

        Net cash generated from financing activities in the nine months ended September 30, 2020 was RMB9,624.2 million (US$1,417.5 million), primarily attributable to proceeds from the private placement of our Class A ordinary shares to certain long-term investors in April 2020.

Table of Contents

        Net cash generated from financing activities in the nine months ended September 30, 2019 was RMB14,960.8 million, primarily attributable to net proceeds from our follow-on public offering and proceeds from issuance of convertible bonds.

Impact of COVID-19 on Our Operations and Financial Performance

        Substantially all of our revenues and workforce are concentrated in China. In early 2020, in response to the intensifying efforts to contain the spread of COVID-19, the Chinese government took a number of actions, which included extending the Chinese New Year holiday, quarantining individuals suspected of having COVID-19, asking residents in China to stay at home and to avoid public gathering, among other things. COVID-19 also resulted in temporary closure of many corporate offices, retail stores, and manufacturing facilities and factories across China, and put significant strain on merchandise shipping and delivery. Many of the quarantine measures within China have since been significantly relaxed as of the date of this prospectus supplement. However, there remain significant uncertainties surrounding the COVID-19 outbreak and its further development as a global pandemic. Hence, the extent of the business disruption and the related impact on our financial results and outlook for 2020 and the periods beyond cannot be reasonably estimated at this time.

        As of September 30, 2020, we had cash and cash equivalents of RMB5,715.7 million (US$841.8 million) and short-term investments of RMB39,859.1 million (US$5,870.6 million). Our short-term investments mainly include time deposits and wealth management products in financial institutions, which are highly liquid. We believe this level of liquidity is sufficient to successfully navigate an extended period of uncertainty. See also "Risk Factors—Risks Related to Our Business and Industry—We face risks related to natural disasters, health epidemics and other outbreaks, most notably those related to the outbreak of COVID-19, which could significantly disrupt our operations."

USE OF PROCEEDS

        We estimate that we will receive net proceeds from this offering of US$3,540.9 million, or US$4,072.0 million if the underwriters exercise their option to purchase additional ADSs in full, after deducting underwriting discounts and the estimated offering expenses payable by us.

        In addition, we expect to receive net proceeds from the sale of the notes in the concurrent Convertible Notes Offering. The net proceeds that we will receive from the Convertible Notes Offering, if completed, are estimated to be approximately US$1,730.8 million (assuming no exercise by the underwriters in the Convertible Notes Offering of their over-allotment option) and US$1,978.0 million (assuming exercise by the underwriters in the Convertible Notes Offering of their over-allotment option in full), after deducting underwriting discounts and the estimated offering expenses payable by us. The completion of this offering is not conditional upon the completion of the Convertible Notes Offering, and the completion of the Convertible Notes Offering is not conditional upon the completion of this offering.

        We currently expect to use the net proceeds from this offering and the concurrent Convertible Notes Offering to further strengthen our balance sheet, providing us flexibility to fund our growth strategies that may include: expansion of our business operations, development of technology infrastructure, strategic investments in our supply chains and ecosystem, and future acquisitions and partnerships. Pending their use, we intend to invest the net proceeds from this offering and the Convertible Notes Offering in short-term, investment grade, interest-bearing instruments or hold them as cash.

        While we currently anticipate that we will use the net proceeds from this offering and the Convertible Note Offering as outlined above based upon our present plans and business conditions, 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.

        In utilizing the proceeds of this offering, we are permitted under PRC laws and regulations to provide funding to our PRC subsidiaries only through loans or capital contributions. Subject to satisfaction of applicable government registration and approval requirements, we may extend inter-company loans to our PRC subsidiaries or make additional capital contributions to our PRC subsidiaries to fund their capital expenditures or working capital. There is, in effect, no statutory limit on the amount of capital contribution that we can make to our PRC subsidiaries. This is because there is no statutory limit on the amount of registered capital for our PRC subsidiaries, and we are allowed to make capital contributions to our PRC subsidiaries by subscribing for their initial registered capital and increased registered capital, provided that the PRC subsidiaries complete the relevant filing and registration procedures. With respect to loans to the PRC subsidiaries by us, (i) if the relevant PRC subsidiaries determine to adopt the traditional foreign exchange administration mechanism, or the Current Foreign Debt mechanism, the outstanding amount of the loans shall not exceed the difference between the total investment and the registered capital of the PRC subsidiaries and there is, in effect, no statutory limit on the amount of loans that we can make to our PRC subsidiaries under this circumstance since we can increase the registered capital of our PRC subsidiaries by making capital contributions to them, subject to the completion of relevant registrations, and the difference between the total investment and the registered capital will increase accordingly; and (ii) if the relevant PRC subsidiaries determine to adopt the foreign exchange administration mechanism as provided in the PBOC Notice No. 9, or the Notice No. 9 Foreign Debt mechanism, which was further amended according to the Circular of the People's Bank of China and the State Administration of Foreign Exchange on Adjusting the Macro-prudential Regulation Parameter for Full-covered Cross-border Financing promulgate by the PBOC on March 11, 2020, or PBOC Notice No. 64, the risk-weighted outstanding amount of the loans, which shall be calculated based on the formula provided in the PBOC

Notice No. 9, shall not exceed 250% of the net assets of the relevant PRC subsidiary. According to the PBOC Notice No. 9, after a transition period of one year since the promulgation of the PBOC Notice No. 9, the People's Bank of China and the State Administration of Foreign Exchange, or SAFE, will determine the cross-border financing administration mechanism for the foreign-invested enterprises after evaluating the overall implementation of the PBOC Notice No. 9. As of the date hereof, neither the People's Bank of China nor SAFE has promulgated and made public any further rules, regulations, notices or circulars in this regard. It is uncertain which mechanism will be adopted by the People's Bank of China and SAFE in the future and what statutory limits will be imposed on us when providing loans to our PRC subsidiaries. In terms of capital contributions, it typically takes about eight weeks to complete the relevant filings and registrations. In terms of loans, the SAFE registration process typically takes about four weeks to complete. While we currently see no material obstacles to completing the filing and registration procedures with respect to future capital contributions and loans to our PRC subsidiaries, we cannot assure you that we will be able to obtain these government registrations or approvals on a timely basis, if at all. See "Item 3. Key Information—D. 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 delay or prevent us from using the proceeds of our offshore financing to make loans or additional capital contributions to our PRC subsidiaries, which could materially and adversely affect our liquidity and our ability to fund and expand our business." of our 2019 Annual Report. It is likely that we will need to convert some of our net proceeds in U.S. dollars into Renminbi in order to use as proceeds as contemplated in this section. For details of PRC regulations governing foreign currency conversion, see "Item 4.B. Information on the Company—Business Overview—Regulation—Regulations Relating to Foreign Exchange" of our 2019 Annual Report.

DIVIDEND POLICY

        Our board of directors has complete discretion on whether to distribute dividends, subject to our memorandum and articles of association and certain requirements of Cayman Islands law. In addition, our shareholders may by ordinary resolution declare a dividend, but no dividend may exceed the amount recommended by our board of directors. 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. 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 "Item 4. Information on the Company—B. Business Overview—Regulation—Regulations Relating to Dividend Distributions" in our 2019 Annual Report.

        If we pay any dividends on our ordinary shares, we will pay those dividends which are payable in respect of the Class A ordinary shares underlying our ADSs to the depositary, as the registered holder of such Class A ordinary shares, and the depositary then will pay such amounts to our ADS holders in proportion to Class A 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" in the accompanying prospectus. Cash dividends on our ordinary shares, if any, will be paid in U.S. dollars.

PRINCIPAL SHAREHOLDERS

        Except as specifically noted, the following table sets forth information with respect to the beneficial ownership of our Class A and Class B ordinary shares as of September 30, 2020 by:

•

each of our directors and executive officers; and



•

each person known to us to beneficially own more than 5% of our total outstanding ordinary shares.

        The calculations in the table below are based on 3,380,761,000 Class A ordinary shares and 1,409,744,080 Class B ordinary shares outstanding as of September 30, 2020.

        Beneficial ownership is determined in accordance with the rules and regulations of the SEC. In computing the number of shares beneficially owned by a person and the percentage ownership of that person, we have included shares that the person has the right to acquire within 60 days of September 30, 2020, including through the exercise of any option, warrant or other right or the conversion of any other security. These shares, however, are not included in the computation of the percentage ownership of any other person.

        To our knowledge, as of September 30, 2020, a total of 1,194,031,072 Class A ordinary shares are held by one record holder in the United States, representing approximately 24.9% of our total outstanding shares. The holder is Deutsche Bank Trust Company Americas, the depositary of our ADS program. None of our outstanding Class B ordinary shares are held by record holders in the United States. The number of beneficial owners of our ADSs in the United States is likely to be much larger than the number of record holders of our ordinary shares in the United States.

TAXATION

        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 prospectus supplement,, 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.

Cayman Islands Taxation

        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.

        Payments of dividends and capital in respect of our ordinary shares and ADSs will not be subject to taxation in the Cayman Islands, and no withholding will be required on the payment of a dividend or capital to any holder of our ordinary shares or ADSs, nor will gains derived from the disposal of our ordinary shares or ADSs be subject to Cayman Islands income or corporation tax.

        No stamp duty is payable in respect of the issue of the shares or on an instrument of transfer in respect of a share.

PRC Taxation

        Under the PRC Enterprise Income Tax Law and its implementation rules, an enterprise established outside the PRC with "de facto management body" within the PRC 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 the PRC; (ii) decisions relating to the enterprise's financial and human resource matters are made or are subject to approval by organizations or personnel in the PRC; (iii) the enterprise's primary assets, accounting books and records, company seals, and board and shareholder resolutions, are located or maintained in the PRC; and (iv) at least 50% of voting board members or senior executives habitually reside in the PRC.

        We believe that Pinduoduo Inc. is not a PRC resident enterprise for PRC tax purposes. Pinduoduo Inc. is not controlled by a PRC enterprise or PRC enterprise group and we do not believe that Pinduoduo Inc. meets all of the conditions above. Pinduoduo Inc. is a company incorporated outside China. As a holding company, its key assets are its ownership interests in its subsidiaries, and its records (including the resolutions of its board of directors and the resolutions of its shareholders)

S-86

Table of Contents

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 Pinduoduo 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 Pinduoduo Inc. would be able to claim the benefits of any tax treaties between their country of tax residence and China in the event that Pinduoduo Inc. is treated as a PRC resident enterprise.

U.S. Federal Income Tax Considerations

        The following discussion is a summary of U.S. federal income tax considerations generally applicable to the ownership and disposition of our ADSs or Class A ordinary shares by a U.S. holder (as defined below) that holds our ADSs or Class A ordinary shares as "capital assets" (generally, property held for investment) under the U.S. Internal Revenue Code of 1986, as amended (the "Code"). This discussion is based upon existing U.S. federal income tax law, which is subject to differing interpretations and may be changed, possibly with retroactive effect. There can be no assurance that the IRS or a court will not take a contrary position. This discussion does not address all aspects of U.S. federal income taxation that may be important to particular investors in light of their individual circumstances, including investors subject to special tax rules (for example, banks and certain financial institutions, insurance companies, pension plans, cooperatives, broker-dealers, traders in securities that have elected the mark-to-market method of accounting for their securities, partnerships and their partners, regulated investment companies, real estate investment trusts, certain former U.S. citizens or long-term residents, persons liable for alternative minimum tax, and tax-exempt organizations (including private foundations)), investors who are not U.S. holders, investors who own (directly, indirectly, or constructively) 10% or more of our stock (by vote or value), investors that will hold their ADSs or Class A 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 summarized below. In addition, this discussion does not discuss any non-U.S., alternative minimum tax, state, or local tax or any non-income tax (such as the U.S. federal gift or estate tax) considerations, 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 Class A ordinary shares.

General

        For purposes of this discussion, a "U.S. holder" is a beneficial owner of our ADSs or Class A 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 laws of, the United States or any state

S-87

Table of Contents

thereof or the District of Columbia, (iii) an estate the income of which is subject to U.S. federal income taxation 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 elected to be treated as a U.S. person under applicable U.S. Treasury regulations.

        If a partnership (or other entity or arrangement treated as a partnership for U.S. federal income tax purposes) is a beneficial owner of our ADSs or Class A 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 Class A ordinary shares and partners in such partnerships are urged to consult their tax advisors as to the particular U.S. federal income tax consequences of an investment in our ADSs or Class A 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. The remainder of this discussion assumes that a U.S. holder of our ADSs will be treated as the beneficial owner of the underlying shares represented by the ADSs. Accordingly, deposits or withdrawals of Class A ordinary shares for ADSs will generally not be subject to U.S. federal income tax.

Passive Foreign Investment Company Considerations

        A non-U.S. corporation, such as our company, will be a "passive foreign investment company," or "PFIC," for U.S. federal income tax purposes, if, in any particular taxable year, 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 (generally determined on the basis of a quarterly average) during such year produce or are held for the production of passive income. Cash is categorized as a passive asset and the company's unbooked intangibles associated with active business activities may generally be classified as active assets. 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, at least 25% (by value) of the stock. Although the law in this regard is unclear, we intend to treat our VIE (including its subsidiaries) as being owned by us for U.S. federal income tax purposes, and we treat it that way, not only because we exercise effective control over the operation of such entity but also because we are entitled to substantially all of its economic benefits, and, as a result, we consolidate its results of operations in our consolidated financial statements. Assuming that we are the owner of our VIE (including its subsidiaries) for U.S. federal income tax purposes, we do not believe that we were a PFIC for the taxable year ended December 31, 2019 and based upon our current income and assets and the value of our ADSs, we do not expect to be classified as a PFIC in the current taxable year or for the foreseeable future.

        While we do not believe that we were a PFIC for the taxable year ended December 31, 2019 and 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 price 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 market capitalization. Among other matters, if our market capitalization subsequently declines, we may be or become a PFIC for the current or future taxable years.

        The determination of whether we will be or become a PFIC will also depend, in part, on the composition of our income and assets, which may be affected by how, and how quickly, we use our liquid assets. If we were treated as not owning our VIE for U.S. federal income tax purposes, our risk of being classified as a PFIC may substantially increase. Because our PFIC status for any taxable year is

S-88

---

Table of Contents

a factual determination that can be made only after the close of a taxable year, there can be no assurance that we will not be a PFIC for the current taxable year or any future taxable year. If we are a PFIC for any year during which a U.S. holder holds our ADSs or Class A 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 Class A ordinary shares.

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

Dividends

        Subject to the PFIC rules discussed below, any cash distributions paid on our ADSs or Class A ordinary shares (including the amount of any tax withheld) 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, in the case of Class A ordinary shares, or by the depositary, in the case of ADSs. Because we do not intend to determine our earnings and profits on the basis of U.S. federal income tax principles, we will generally report any distribution paid as a dividend for U.S. federal income tax purposes. Dividends received on the ADSs or Class A ordinary shares will not be eligible for the dividends received deduction allowed to corporations.

        Individuals and other non-corporate U.S. holders will generally be subject to tax at the lower capital gain tax rate applicable to "qualified dividend income," provided that certain conditions are satisfied, including that (1) our ADSs are readily tradable on an established securities market in the United States, or, in the event that we are deemed to be a PRC resident enterprise under the PRC tax law, we are eligible for the benefit of the United States-PRC income tax treaty, (2) we are neither a PFIC nor treated as such with respect to a U.S. holder (as discussed below) for the taxable year in which the dividend was paid and the preceding taxable year, and (3) certain holding period requirements are met. Our ADSs are listed on the Nasdaq Global Select Market. We believe that the ADSs are readily tradable on an established securities market in the United States and that we are a qualified foreign corporation with respect to dividends paid on the ADSs. There can be no assurance that our ADSs will continue to be considered readily tradable on an established securities market in later years. Since we do not expect that our Class A ordinary shares will be listed on established securities markets, we do not believe that dividends that we pay on our Class A ordinary shares that are not backed by ADSs currently meet the conditions required for the reduced tax rate. However, in the event we are deemed to be a resident enterprise under the PRC Enterprise Income Tax Law, we may be eligible for the benefits of the United States-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 Class A ordinary shares as well as our 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 Class A ordinary shares.

        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 Enterprise Income Tax Law, a U.S. holder may be subject to PRC withholding taxes on dividends paid on our ADSs or Class A ordinary shares. See "Taxation—PRC Taxation". In that case, a U.S. holder may be eligible, subject to a number of complex limitations, to claim a foreign tax credit in respect of any foreign withholding taxes imposed on dividends received on ADSs or Class A ordinary shares. A U.S. holder who does not elect to claim a foreign tax credit for

S-89

---

Table of Contents

foreign tax withheld may instead claim a deduction, for U.S. federal income tax purposes, in respect of such withholdings, but only for a year in which such U.S. holder elects to do so for all creditable foreign income taxes. The rules governing the foreign tax credit are complex. U.S. holders are advised to consult their tax advisors regarding the availability of the foreign tax credit under their particular circumstances.

Sale or Other Disposition of ADSs or Class A Ordinary Shares

        Subject to the PFIC rules discussed below, a U.S. holder will generally recognize capital gain or loss upon the sale or other disposition of ADSs or Class A ordinary shares in an amount equal to the difference between the amount realized upon the disposition and the U.S. holder's adjusted tax basis in such ADSs or Class A ordinary shares. Any capital gain or loss will be long-term if the ADSs or Class A 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 gains of individuals and other non-corporate U.S. holders generally are 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 Class A 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 a U.S. holder is not eligible for the benefits of the income tax treaty or fails to make the election to treat any gain as foreign source, then such U.S. holder may not be able to use the foreign tax credit arising from any PRC tax imposed on the disposition of the ADSs or Class A 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 advised to consult their tax advisors regarding the tax consequences if a foreign tax is imposed on a disposition of our ADSs or Class A ordinary shares, including the availability of the foreign tax credit under their particular circumstances and the election to treat any gain as PRC source.

Passive Foreign Investment Company Rules

        If we are a PFIC for any taxable year during which a U.S. holder holds our ADSs or Class A 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, for subsequent taxable years, 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% 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 Class A ordinary shares), and (ii) any gain realized on the sale or other disposition, including, under certain circumstances, a pledge, of ADSs or Class A ordinary shares. Under the PFIC rules:

•

such excess distribution and/or gain will be allocated ratably over the U.S. holder's holding period for the ADSs or Class A ordinary shares;



•

such amount allocated to the current taxable year and any taxable years in the U.S. holder's holding period prior to the first taxable year in which we are a PFIC, or pre-PFIC year, will be taxable as ordinary income;



•

such amount allocated to each prior taxable year, other than a pre-PFIC year, will be subject to tax at the highest tax rate in effect for that year; and



•

an interest charge generally applicable to underpayments of tax will be imposed on the tax attributable to each prior taxable year, other than a pre-PFIC year.

S-90

Table of Contents

        If we are a PFIC for any taxable year during which a U.S. holder holds our ADSs or Class A ordinary shares and any of our non-U.S. 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 advised 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 our ADSs, but not our Class A ordinary shares provided that the ADSs are regularly traded on the Nasdaq Global Select Market. Our ADSs are expected to qualify as being regularly traded, but no assurances may be given in this regard. Because a mark-to-market election technically cannot be made for any lower-tier PFICs that a PFIC may own, a U.S. holder who makes a mark-to-market election with respect to our ADSs will generally 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.

        If a U.S. holder makes a mark-to-market election with respect to our ADSs, the U.S. 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 only to the extent of the net 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. Further, in each year that we are a PFIC any gain recognized upon the sale or other disposition of the ADSs will be treated as ordinary income and loss will be treated as ordinary loss, but only 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 regularly traded on a qualified exchange or the IRS consents to the revocation of the election. It should also be noted that only the ADSs and not the Class A ordinary shares are listed on the Nasdaq Global Select Market. Consequently, if a U.S. holder holds Class A ordinary shares that are not represented by ADSs, such holder will generally not be eligible to make a mark-to-market election if we are or were to become a PFIC.

        If a U.S. holder makes a mark-to-market election in respect of a PFIC and such corporation ceases to be a PFIC, the U.S. holder will not be required to take into account the mark-to-market gain or loss described above during any period that such corporation is not a PFIC.

        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 (and generally less adverse than) the general tax treatment for PFICs described above.

        If a U.S. holder owns our ADSs or Class A ordinary shares during any taxable year that we are a PFIC, such holder would generally be required to file an annual IRS Form 8621. Each U.S. holder is advised to consult its tax advisors regarding the potential tax consequences to such holder if we are or become a PFIC, including the possibility of making a mark-to-market election.

BENEFIT PLAN INVESTOR CONSIDERATIONS

        The following is a summary of certain considerations associated with the purchase of the ADSs (including any interest therein) by (i) an "employee benefit plan" (as defined in Section 3(3) of the United States Employee Retirement Income Security Act of 1974, as amended ("ERISA")) that is subject to Title I of ERISA, (ii) a "plan" described in and subject to Section 4975 of the Code, including, without limitation, an individual retirement account and an individual retirement annuity ("IRA"), (iii) an entity deemed to hold "plan assets" of any of the foregoing for purposes of ERISA by reason of an employee benefit plan's or plan's investment in such entity, or (iv) a governmental plan, church plan or non-U.S. plan subject to applicable law that is substantially similar to the fiduciary responsibility or prohibited transaction provisions of ERISA or Section 4975 of the Code ("Similar Law"). Each of the foregoing is referred to herein as a "Plan."

General Fiduciary Matters

        ERISA imposes certain duties on persons who are fiduciaries of a Plan subject to Title I of ERISA, and ERISA and the Code prohibit certain transactions involving the assets of a Plan that is subject to ERISA and/or Section 4975 of the Code (a "Covered Plan") and certain "parties in interest," within the meaning of Section 3(14) of ERISA, or "disqualified persons," within the meaning of Section 4975(e)(2) of the Code. Under ERISA and the Code, any person who exercises authority or control over the management or disposition of the assets of a Covered Plan, or who renders investment advice for a fee or other compensation, direct or indirect, with respect to the assets of a Covered Plan, is generally considered to be a fiduciary of the Covered Plan. Neither we, the underwriters or any of our or their affiliates or agents (the "Transaction Parties") will undertake to provide impartial investment advice, or to give advice in a fiduciary capacity to any Covered Plan in connection with the Plan's acquisition, holding or disposition of any ADS.

        In considering whether to invest the assets of any Plan in an ADS, a fiduciary of a Plan should determine, among other things, whether the investment is in accordance with the documents and instruments governing such Plan and the applicable provisions of ERISA, the Code or any provisions of Similar Law relating to a fiduciary's duties to such Plan, including, without limitation, to the extent applicable, the prudence, diversification, delegation of control, conflict of interest and prohibited transaction provisions of ERISA, the Code and any Similar Law.

Prohibited Transaction Issues

        Section 406 of ERISA and Section 4975 of the Code prohibit Covered Plans from engaging in specified transactions involving "plan assets" with persons or entities who are parties in interest or disqualified persons with respect thereto, unless an exemption is available. For example, a Covered Plan is prohibited from lending money (or otherwise extending credit) to a party in interest or disqualified person, unless an exemption is available. A party in interest or disqualified person who engages in a non-exempt prohibited transaction may be subject to excise taxes and other penalties and liabilities under ERISA and the Code, any fiduciary who authorizes such a transaction may be subject to personal liability, and any such transaction may need to be reversed or otherwise corrected. In addition, if the Plan involved in certain non-exempt prohibited transactions is an IRA, the IRA could lose its tax-exempt status. An investment in an ADS by a Covered Plan may constitute or result in a direct or indirect prohibited transaction under Section 406 of ERISA and/or Section 4975 of the Code, for example, where we or the underwriters are considered to be a party in interest or a disqualified person with respect to such Plan, unless the investment is acquired and held in accordance with an applicable statutory or administrative prohibited transaction exemption. In this regard, the U.S. Department of Labor has issued prohibited transaction class exemptions, or "PTCEs," that potentially may apply to the acquisition and holding of a note (including any interest in a note) and the receipt and holding of the ADSs deliverable upon conversion of the note. These class exemptions include,

Table of Contents

without limitation, PTCE 84-14, relating to transactions effected by independent qualified professional asset managers, PTCE 90-1, relating to investments by insurance company pooled separate accounts, PTCE 91-38, relating to investments by bank collective investment funds, PTCE 95-60, relating to investments by life insurance company general accounts, and PTCE 96-23, relating to transactions directed by in-house asset managers. In addition to the foregoing, Section 408(b)(17) of ERISA and Section 4975(d)(20) of the Code provide exemptions for transactions between a Covered Plan and a person that is a party in interest and/or a disqualified person with respect to that Plan (other than a fiduciary or an affiliate that, directly or indirectly, has or exercises discretionary authority or control, or renders investment advice with respect to, the Plan assets involved in the transaction) solely by reason of providing services to the Plan or by relationship to a service provider, provided that, in connection with the transaction, the Plan receives no less, nor pays no more, than adequate consideration. There can be no assurance that any of the foregoing exemptions or any other exemption will be available with respect to an otherwise prohibited transaction resulting from a Covered Plan's investment in ADSs, or that all of the conditions of any such exemptions will be satisfied.

        Governmental plans, church plans and non-U.S. plans that are subject to Similar Law may purchase or hold a note (including any interest in a note) only in compliance with such Similar Law, including any applicable statutory or administrative prohibited transaction exemption available under such Similar Law.

Representation

        Because of the foregoing, the ADSs (including any interest in therein) may not be purchased or held by any person investing assets of any Plan, unless such purchase and holding will not constitute a non-exempt prohibited transaction under ERISA and the Code or a violation of any Similar Law. Accordingly, each purchaser of an ADS will be deemed to, and may be required to, represent and warrant that either (i) it is not using assets of a Plan to purchase or hold an ADS, or (ii) its investment in the ADSs will not result in a violation of the fiduciary rules under ERISA or a prohibited transaction under ERISA or Section 4975 of the Code, or will be exempt pursuant to one or more statutory or administrative prohibited transaction exemptions, and will not violate any applicable Similar Law.

Consultation with Counsel

        The foregoing discussion is general in nature and is not intended to be all-inclusive. Due to the complexity of these rules and the penalties that may be imposed on persons involved in nonexempt prohibited transactions, it is particularly important that fiduciaries, or other persons considering investing in an ADS on behalf of, or with the assets of, any Plan, consult with their counsel regarding the potential applicability of ERISA, Section 4975 of the Code and any Similar Law to such investment and whether an exemption would be necessary and applicable to the purchase or holding of ADSs.

        The sale of notes (including any interest therein) to a Plan is in no respect a representation or advice by a Transaction Party that such an investment meets all relevant legal requirements with respect to investments by Plans generally or any particular Plan or that such an investment is appropriate or recommended for Plans generally or for any particular Plan.

UNDERWRITING

        Under the terms and subject to the conditions contained in an underwriting agreement dated the date of this prospectus supplement, we have agreed to sell to the underwriters named below, for whom Goldman Sachs (Asia) L.L.C. and BofA Securities, Inc. are acting as representatives, the following respective numbers of ADSs:

        The underwriting agreement provides that the underwriters are obligated to purchase all ADSs in the offering if any are purchased, other than those ADSs covered by the option to purchase additional shares 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. All sales of ADSs in the United States will be made by U.S. registered broker-dealers.

        We have granted to the underwriters a 30-day option to purchase on a pro rata basis up to 3,300,000 additional ADSs from us at the public offering price less the underwriting 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.

        The underwriters propose to offer ADSs initially at the public offering price on the cover page of this prospectus supplement and to selling group members at that price less a selling concession of US$0.975 per ADS. After the public offering of the ADSs, the representatives may change the public offering price and concession and discount to broker/dealers.

        The following table shows the public offering price, the underwriting discounts and commissions that we are to pay the underwriters and the proceeds, before expenses, to us in connection with this offering. Such amounts are shown assuming both no exercise and full exercise of the underwriters' option to purchase additional ADSs.

        The underwriters have informed us that they do not expect sales to accounts over which the underwriters have discretionary authority to exceed 5% of ADSs being offered.

        The underwriters will reimburse us for our expenses incurred in connection with this offering in an amount of up to US$4.1 million.

        We have agreed that we will not (a) offer, sell, contract to sell, pledge, grant any option to purchase or otherwise dispose of, directly or indirectly, any ordinary shares or ADSs or any securities convertible into or exchangeable or exercisable for any of our ordinary shares or ADSs, (b) enter into any swap, hedge or other agreement that transfers to another, in whole or in part, any of the economic

consequences of ownership of the ordinary shares or ADSs, (c) file with the SEC a registration statement under the Securities Act relating to, any ADSs, our ordinary shares or securities convertible into or exchangeable or exercisable for any ADSs or our ordinary shares, or (d) publicly disclose the intention to make any offer, sale, pledge, disposition or filing, without the prior written consent of Goldman Sachs (Asia) L.L.C. and BofA Securities, Inc. and subject to certain exceptions, for a period of 90 days after the date of this prospectus supplement.

        Our directors and executive officers have agreed that they will not offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, any ADSs, our ordinary shares or securities convertible into or exchangeable or exercisable for any ADSs or our ordinary shares, enter into a transaction that would have the same effect, or enter into any swap, hedge or other arrangement that transfers, in whole or in part, any of the economic consequences of ownership of ADSs or our ordinary shares, whether any of these transactions are to be settled by delivery of ADSs or our ordinary shares or other securities, in cash or otherwise, or publicly disclose the intention to make any offer, sale, pledge or disposition, or to enter into any transaction, swap, hedge or other arrangement, without, in each case, the prior written consent of Goldman Sachs (Asia) L.L.C. and BofA Securities, Inc. for a period of 90 days after the date of this prospectus supplement, subject to certain exceptions, including, among others, (a) the issuance of ADSs or ordinary shares upon the exercise of any outstanding options, (b) the issuance of ADSs to settle conversions of the 2024 Notes, and (c) the sale of ADSs or ordinary shares held by Sequoia and its affiliated entities.

        Concurrently with this offering, we are offering US$1,750 million aggregate principal amount of the convertible notes, assuming no exercise of the underwriters' over-allotment option (or up to US$2,000 million aggregate principal amount of the convertible notes assuming their full exercise of their over-allotment option), in an underwritten offering pursuant to a separate prospectus supplement and accompanying prospectus. The closing of this offering of the ADSs is not contingent upon the closing of the concurrent offering of the convertible notes, and the closing of the concurrent offering of the convertible notes is not contingent upon the closing of this offering of the ADSs. We cannot assure you that the concurrent offering of the convertible notes will be completed or, if completed, on what terms any of them will be completed. This prospectus supplement does not constitute an offer to sell or the solicitation of an offer to buy the convertible notes.

        We have agreed to indemnify the underwriters against liabilities under the Securities Act, or contribute to payments that the underwriters may be required to make in that respect.

        Our ADSs are listed on the Nasdaq Global Select Market under the symbol "PDD."

        In connection with the offering, the underwriters may engage in stabilizing transactions, over-allotment transactions, syndicate covering transactions and penalty bids in accordance with Regulation M under the Exchange Act.

•

Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum.



•

Over-allotment involves sales by the underwriters of ADSs in excess of the number of ADSs the underwriters are obligated to purchase, which creates a syndicate short position. The short position may be either a covered short position or a naked short position. In a covered short position, the number of ADSs over-allotted by the underwriters is not greater than the number of ADSs that they may purchase in the option to purchase additional shares. In a naked short position, the number of ADSs involved is greater than the number of ADSs in the option to purchase additional shares. The underwriters may close out any covered short position by either exercising their option to purchase additional shares and/or purchasing ADSs in the open market.

Table of Contents

•

Syndicate covering transactions involve purchases of ADSs in the open market after the distribution has been completed in order to cover syndicate short positions. In determining the source of ADSs to close out the 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 ADSs through the option to purchase additional shares. If the underwriters sell more ADSs than could be covered by the option to purchase additional shares, a naked short position, the position can only be closed out by buying ADSs in the open market. A naked short position is more likely to be created if the underwriters are concerned that there could 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.



•

Penalty bids permit the representatives to reclaim a selling concession from a syndicate member when ADSs originally sold by the syndicate member is purchased in a stabilizing or syndicate covering transaction to cover syndicate short positions.

        These stabilizing transactions, syndicate covering transactions and penalty bids may have the effect of raising or maintaining the market price of ADSs or preventing or retarding a decline in the market price of ADSs. As a result the price of ADSs may be higher than the price that might otherwise exist in the open market. These transactions may be effected on the Nasdaq or otherwise and, if commenced, may be discontinued at any time.

        This prospectus supplement and accompanying prospectus in electronic format may be made available on the web sites maintained by one or more of the underwriters, or selling group members, if any, participating in this offering and one or more of the underwriters participating in this offering may distribute prospectus supplement and accompanying prospectus electronically. The representatives may agree to allocate a number of ADSs to underwriters and selling group members for sale to their online brokerage account holders.

DESCRIPTION OF SHARE CAPITAL

        We are a Cayman Islands exempted company with limited liability and our corporate affairs are governed by our memorandum and articles of association, as amended and restated from time to time, the Companies Law (as amended) of the Cayman Islands, which is referred to as the Companies Law below, and the common law of the Cayman Islands.

        As of the date of this prospectus, the authorized share capital of our company is US$400,000 divided into 80,000,000,000 shares comprising of (i) 77,300,000,000 Class A Ordinary Shares of a par value of US$0.000005 each, (ii) 2,200,000,000 Class B Ordinary Shares of a par value of US$0.000005 each and (iii) 500,000,000 shares of a par value of US$0.000005 each of such class or classes (however designated) as the board of directors may determine in accordance with the ninth amended and restated memorandum and articles of association of our company.

        The following are summaries of material provisions of our memorandum and articles of association and the Companies Law insofar as they relate to the material terms of our ordinary shares.

Ordinary Shares

        Objects of Our Company.    Under our 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 divided into Class A ordinary shares and Class B ordinary shares. Holders of our Class A ordinary shares and Class B ordinary shares will have the same rights except for voting and conversion rights. Each Class A ordinary share shall entitle the holder thereof to one (1) vote on all matters subject to vote at our general meetings, and each Class B ordinary share shall entitle the holder thereof to ten (10) votes on all matters subject to vote at our general meetings. Our ordinary shares are issued in registered form and are issued when registered in our register of members.

        Conversion.    Each Class B ordinary share is convertible into one Class A ordinary share at any time by the holder thereof. Class A ordinary shares are not convertible into Class B ordinary shares under any circumstances. Upon any sale, transfer, assignment or disposition of any Class B ordinary shares by a holder thereof to any person other than Mr. Zheng Huang or any entity which is not ultimately controlled by Mr. Zheng Huang, such Class B ordinary shares shall be automatically and immediately converted into the same number of Class A ordinary shares.

        Dividends.    The holders of our ordinary shares are entitled to such dividends as may be declared by our board of directors. Under the laws of the Cayman Islands, our company may declare and 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 Class A ordinary shares and Class B 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 provided for in our memorandum and articles of association. In respect of matters requiring shareholders' vote, each Class A ordinary share is entitled to one vote, and each Class B ordinary share is entitled to ten votes. At any general meeting a resolution put to the vote of the meeting shall be decided on a show of hands, unless a poll is (before or on the declaration of the result of the show of hands) demanded by the chairman.

        A quorum required for a meeting of shareholders consists of one or more shareholders holding not less than a majority of all votes attaching to all of our shares in issue and entitled to vote present in person or by proxy or, if a corporation or other non-natural person, by its duly authorized

representative. Advance notice of at least ten calendar days is required for the convening of our annual general meeting and other shareholders meetings.

        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 issued and outstanding shares at a meeting. Our articles of association provide that a special resolution shall be required, and that for the purposes of any such special resolution, the affirmative vote of no less than 95% of votes cast by the shareholders entitled to vote who are present in person or by proxy at a general meeting shall be required to approve any amendments to any provisions of our articles of association that relate to or have an impact upon: (i) the right of the Pinduoduo Partnership to appoint executive directors and nominate the chief executive officer candidate of our company as described under "Item 6. Directors, Senior Management and Employees—A. Directors and Senior Management—Pinduoduo Partnership—Executive Director Appointment and CEO Nomination Right" in our annual report on Form 20-F for the year ended December 31, 2019 and (ii) the procedures regarding the election, appointment and removal of directors or size of the board. Both ordinary resolutions and special resolutions may also be passed by a unanimous written resolution signed by all the shareholders of our company, as permitted by the Companies Law and our memorandum and articles of association. 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 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 the chairman or a majority of our board of directors. Advance notice of at least ten (10) calendar 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 one or more shareholders present or by proxy, representing not less than a majority 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 memorandum and articles of association provide that upon the requisition of shareholders representing in aggregate not less than one-third of all votes attaching to all issued and outstanding shares of our company that as at the date of the deposit carry the right to vote at general meetings of our company, our board of directors will convene an extraordinary general meeting and put the resolutions so requisitioned to a vote at such meeting. However, our 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 in respect of a nil or partly paid up share, or the directors so require, shall also be executed by the transferee.

7

---

Table of Contents

        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:

•

the instrument of transfer is lodged with us, accompanied by the certificate for the ordinary shares to which it relates and such other evidence as our board of directors may reasonably require to show the right of the transferor to make the transfer;



•

the instrument of transfer is in respect of only one class of ordinary shares;



•

the instrument of transfer is properly stamped, if required;



•

in the case of a transfer to joint holders, the number of joint holders to whom the ordinary share is to be transferred does not exceed four; and



•

a fee of such maximum sum as the Nasdaq Global Select Market may determine to be payable or such lesser sum as our directors may from time to time require is paid to us in respect thereof.

        If our directors refuse to register a transfer they shall, within three calendar 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 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 calendar days in any calendar 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 calendar days prior to the specified time 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, or by the shareholders by special resolutions. 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

Table of Contents

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, our share capital is divided into different classes of shares, the rights attached to any class of shares (subject to any rights or restrictions for the time being attached to any class), may be varied with the consent in writing of the holders of two-thirds of the issued shares of that class or with the sanction of a resolution passed at a separate meeting of the holders of the shares of the class by the holders of two-thirds of the issued shares of that class. 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 memorandum and articles 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 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:

•

the designation of the series;



•

the number of shares of the series;



•

the dividend rights, dividend rates, conversion rights, voting rights; and



•

the rights and terms of redemption and liquidation preferences.

        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 (except for our memorandum and articles of association and our register of mortgages and charges). However, we will provide our shareholders with annual audited financial statements.

        Anti-Takeover Provisions.    Some provisions of our 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:

•

authorize our board of directors to issue preference shares in one or more series and to designate the price, rights, preferences, privileges and restrictions of such preference shares without any further vote or action by our shareholders; and



•

limit the ability of shareholders to requisition and convene general meetings of shareholders.

        However, under Cayman Islands law, our directors may only exercise the rights and powers granted to them under our 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

9

---

Table of Contents

exempted company are essentially the same as for an ordinary company except that an exempted company:

•

does not have to file an annual return of its shareholders with the Registrar of Companies;



•

is not required to open its register of members for inspection;



•

does not have to hold an annual general meeting;



•

may issue negotiable or bearer shares or shares with no par value;



•

may obtain an undertaking against the imposition of any future taxation (such undertakings are usually given for 20 years in the first instance);



•

may register by way of continuation in another jurisdiction and be deregistered in the Cayman Islands;



•

may register as an exempted limited duration company; and



•

may register as a segregated portfolio 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.

Registered Office and Objects

        Our registered office in the Cayman Islands is located at the offices of Vistra (Cayman) Limited, P.O. Box 31119 Grand Pavilion, Hibiscus Way, 802 West Bay Road, Grand Cayman, KY1-1205, Cayman Islands, or at such other location within the Cayman Islands as our directors may from time to time decide. The objects for which our company is established are unrestricted and we have full power and authority to carry out any object not prohibited by the Companies Law or any other law of the Cayman Islands.

Board of Directors

        Our board of directors consists of seven directors. A director is not required to hold any shares in our company by way of qualification. A director may vote with respect to any contract or transaction or proposed contract or transaction notwithstanding that he may be interested therein provided (a) such director has declared the nature of his interest at the earliest meeting of the board at which it is practicable for him to do so, either specifically or by way of a general notice and (b) if such contract or arrangement is a transaction with a related party, such transaction has been approved by the audit committee. The directors may from time to time at their discretion exercise all the powers of the company to raise or borrow money, mortgage or charge its undertaking, property and assets (present and future) and uncalled capital or any part thereof, to issue debentures, debenture stock, bonds and other securities, whether outright or as collateral security for any debt, liability or obligation of the company or of any third party. None of our non-executive directors has a service contract with us that provides for benefits upon termination of service.

        We have a compensation committee that assists the board in reviewing and approving the compensation structure and form of compensation of our directors and executive officers. Members of the compensation committee are not prohibited from direct involvement in determining their own compensation. Our chief executive officer may not be present at any committee meeting during which his compensation is deliberated.

Differences in Corporate Law

        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 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

11

Table of Contents

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 statutory provisions as to the required majority vote have been met;



•

the shareholders have been fairly represented at the meeting in question and the statutory majority are acting bona fide without coercion of the minority to promote interests adverse to those of the class;



•

the arrangement is such that may be reasonably approved by an intelligent and honest man of that class acting in respect of his interest; and



•

the arrangement is not one that would more properly be sanctioned under some other provision of the Companies Law.

        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:

•

a company acts or proposes to act illegally or ultra vires;



•

the act complained of, although not ultra vires, could only be effected duly if authorized by more than a simple majority vote that has not been obtained; and



•

those who control the company are perpetrating a "fraud on the minority."

        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 memorandum and articles of association permit indemnification of officers and directors against all actions, proceedings, costs, charges, expenses, losses, damages or liabilities incurred or sustained by such officers and directors, other than by reason of such officer's or director's own dishonesty, willful default or fraud, in or about the conduct of our business or affairs (including as a result of any mistake of judgment) or in the execution or discharge of his or her duties, powers, authorities or discretions, including without prejudice to the generality of the foregoing, any costs, expenses, losses or liabilities incurred by such officer and director in defending (whether successfully or otherwise) any civil proceedings concerning us or our affairs in any court whether in the Cayman Islands or elsewhere. This standard of conduct is generally the same as permitted under the Delaware General Corporation Law for a Delaware corporation.

12

Table of Contents

        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 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 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 articles of

13

---

Table of Contents

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 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 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 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.

14

Table of Contents

        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 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 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 two-thirds of the issued shares of that class or with the sanction of a resolution passed at a general meeting of the holders of the shares of that class by holders of two-thirds of the issued 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 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 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 memorandum and articles of association governing the ownership threshold above which shareholder ownership must be disclosed.

History of Securities Issuances

        The following is a summary of our securities issuances in the past three years.

Ordinary Shares

        We were incorporated in the Cayman Islands in April 2015. In February 2017, we repurchased 2,821,509 ordinary shares (equivalent to 56,430,180 ordinary shares if the recapitalization steps in connection with the Series D financing were similarly applied) from Pure Treasure Limited at a consideration of US$20,000,000.00.

The consideration paid by Tencent consisted of both cash and certain business and strategic cooperation pursuant to and as specified in the Strategic Cooperation Framework Agreement between us and an affiliate of Tencent, dated February 27, 2018.

        Immediately prior to the completion of our initial public offering on July 30, 2018, all preferred shares that were issued and outstanding at the time were converted into our ordinary shares on a one-for-one basis.

Option Grants

        We have granted options to purchase our ordinary shares to certain of our directors, executive officers and employees.

Registration Rights

        We entered into our seventh amended and restated shareholders agreement on March 5, 2018 with our then shareholders. Pursuant to this shareholders agreement, 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 30% or more of the issued and outstanding registrable securities (on an as converted basis) held by the preferred shareholders, the Class B ordinary shareholders and Class A 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 we determine 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 for more than once during any twelve-month period and cannot register any other securities during such 90-day period. We are not obligated to effect more than two demand registrations. Further, if the registrable securities are offered by means of an underwritten offering, and the underwriters advise us that marketing factors require a limitation of the number of securities to be underwritten, the number of registrable securities that may be included in the underwriting shall be reduced as required by the underwriters and allocated among the holders of registrable securities on a pro rata basis according to the number of registrable securities requested by each holder, provided that all other equity securities are first excluded and 25% of shares of registrable securities requested by the holders are included.

        Registration on Form F-3.    Any holder may request us to file a registration statement on Form F-3 if we qualify for registration on Form F-3. The holders are entitled to an unlimited number of registrations on Form F-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 60 days if we determine 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 for more than once during any twelve-month period and cannot register any other securities during such 60-day 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 notify all holders of registrable securities and offer them an opportunity to be included in such registration. If the managing underwriter determines in good faith that market factors require a limitation of the number of registrable securities to be underwritten, the managing underwriter may decide to exclude shares from the registration and the underwriting, and the number of shares that may be included in the registration and the underwriting will be allocated, first, to us, second, to each of the holders requesting inclusion of their registrable securities on a pro rata basis based on the total amount of registrable securities requested by each such holder, and third, to holders of other securities of our company, provided that all other equity securities are first excluded and 25% of shares of registrable securities requested by the holders are included.

        Expenses of Registration.    We will bear all registration expenses, other than the underwriting discounts and commissions, fees for special counsel for the holders participating in such registration and certain excepted expenses as described in the shareholders agreement, 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 registration upon (i) the fifth anniversary from the date of closing of a Qualified Initial Public Offering (as defined in the shareholders agreement), (ii) upon the termination, liquidation or dissolution of our company or a Liquidation Event (as defined in the shareholders agreement), or (iii) all registrable securities proposed to be sold by a holder may then be sold without registration in any 90-day period under Rule 144 of the Securities Act.

DESCRIPTION OF AMERICAN DEPOSITARY SHARES

American Depositary Shares

        Deutsche Bank Trust Company Americas, as depositary, will register and deliver the ADSs. Each ADS will represent ownership of four Class A ordinary shares, deposited with Deutsche Bank AG, Hong Kong Branch, as custodian for the depositary. Each ADS will also represent ownership of any other securities, cash or other property which may be held by the depositary. The depositary's corporate trust office at which the ADSs will be administered is located at 60 Wall Street, New York, NY 10005, USA. The principal executive office of the depositary is located at 60 Wall Street, New York, NY 10005, USA.

        The Direct Registration System, or DRS, is a system administered by The Depository Trust Company, or DTC, pursuant to which the depositary may register the ownership of uncertificated ADSs, which ownership shall be evidenced by periodic statements issued by the depositary to the ADS holders entitled thereto.

        We will not treat ADS holders as our shareholders and accordingly, you, as an ADS holder, will not have shareholder rights. Cayman Islands law governs shareholder rights. The depositary will be the holder of the Class A ordinary shares underlying your ADSs. As a holder of ADSs, you will have ADS holder rights. A deposit agreement among us, the depositary and you, as an ADS holder, and the beneficial owners of ADSs sets out ADS holder rights as well as the rights and obligations of the depositary. The laws of the State of New York govern the deposit agreement and the ADSs. See "—Jurisdiction and Arbitration."

        The following is a summary of the material provisions of the deposit agreement. For more complete information, you should read the entire deposit agreement and the form of American Depositary Receipt. For directions on how to obtain copies of those documents, see "Where You Can Find Additional Information."

Holding the ADSs

How will you hold your ADSs?

        You may hold ADSs either (1) directly (a) by having an American Depositary Receipt, or ADR, which is a certificate evidencing a specific number of ADSs, registered in your name, or (b) by holding ADSs in DRS, or (2) indirectly through your broker or other financial institution. If you hold ADSs directly, you are an ADS holder. This description assumes you hold your ADSs directly. ADSs will be issued through DRS, unless you specifically request certificated ADRs. If you hold the ADSs indirectly, you must rely on the procedures of your broker or other financial institution to assert the rights of ADS holders described in this section. You should consult with your broker or financial institution to find out what those procedures are.

Dividends and Other Distributions

How will you receive dividends and other distributions on the shares?

        The depositary has agreed to pay to you the cash dividends or other distributions it or the custodian receives on Class A ordinary shares or other deposited securities, after deducting its fees and expenses. You will receive these distributions in proportion to the number of Class A ordinary shares your ADSs represent as of the record date (which will be as close as practicable to the record date for our Class A ordinary shares) set by the depositary with respect to the ADSs.

•

Cash.  The depositary will convert or cause to be converted any cash dividend or other cash distribution we pay on the Class A ordinary shares or any net proceeds from the sale of any Class A ordinary shares, rights, securities or other entitlements under the terms of the deposit

18

Table of Contents

agreement into U.S. dollars if it can do so on a practicable basis, and can transfer the U.S. dollars to the United States and will distribute promptly the amount thus received. If the depositary shall determine in its judgment that such conversions or transfers are not practical or lawful or if any government approval or license is needed and cannot be obtained at a reasonable cost within a reasonable period or otherwise sought, the deposit agreement allows the depositary to distribute the foreign currency only to those ADS holders to whom it is possible to do so. It will hold or cause the custodian to hold the foreign currency it cannot convert for the account of the ADS holders who have not been paid and such funds will be held for the respective accounts of the ADS holders. It will not invest the foreign currency and it will not be liable for any interest for the respective accounts of the ADS holders.

•

Before making a distribution, any taxes or other governmental charges, together with fees and expenses of the depositary, that must be paid, will be deducted. See "Taxation." It will distribute only whole U.S. dollars and cents and will round down fractional cents to the nearest whole cent. If the exchange rates fluctuate during a time when the depositary cannot convert the foreign currency, you may lose some or all of the value of the distribution.



•

Shares.  For any Class A ordinary shares we distribute as a dividend or free distribution, either (1) the depositary will distribute additional ADSs representing such Class A ordinary shares or (2) existing ADSs as of the applicable record date will represent rights and interests in the additional Class A ordinary shares distributed, to the extent reasonably practicable and permissible under law, in either case, net of applicable fees, charges and expenses incurred by the depositary and taxes and/or other governmental charges. The depositary will only distribute whole ADSs. It will try to sell Class A ordinary shares which would require it to deliver a fractional ADS and distribute the net proceeds in the same way as it does with cash. The depositary may sell a portion of the distributed Class A ordinary shares sufficient to pay its fees and expenses, and any taxes and governmental charges, in connection with that distribution.



•

Elective Distributions in Cash or Shares.  If we offer holders of our Class A ordinary shares the option to receive dividends in either cash or shares, the depositary, after consultation with us and having received timely notice as described in the deposit agreement of such elective distribution by us, has discretion to determine to what extent such elective distribution will be made available to you as a holder of the ADSs. We must timely first instruct the depositary to make such elective distribution available to you and furnish it with satisfactory evidence that it is legal to do so. The depositary could decide it is not legal or reasonably practicable to make such elective distribution available to you. In such case, the depositary shall, on the basis of the same determination as is made in respect of the Class A ordinary shares for which no election is made, distribute either cash in the same way as it does in a cash distribution, or additional ADSs representing Class A ordinary shares in the same way as it does in a share distribution. The depositary is not obligated to make available to you a method to receive the elective dividend in shares rather than in ADSs. There can be no assurance that you will be given the opportunity to receive elective distributions on the same terms and conditions as the holders of Class A ordinary shares.



•

Rights to Purchase Additional Shares.  If we offer holders of our Class A ordinary shares any rights to subscribe for additional shares, the depositary shall having received timely notice as described in the deposit agreement of such distribution by us, consult with us, and we must determine whether it is lawful and reasonably practicable to make these rights available to you. We must first instruct the depositary to make such rights available to you and furnish the depositary with satisfactory evidence that it is legal to do so. If the depositary decides it is not legal or reasonably practicable to make the rights available but that it is lawful and reasonably practicable to sell the rights, the depositary will endeavor to sell the rights and in a riskless principal capacity or otherwise, at such place and upon such terms (including public or private

sale) as it may deem proper distribute the net proceeds in the same way as it does with cash. The depositary will allow rights that are not distributed or sold to lapse. In that case, you will receive no value for them.

If the depositary makes rights available to you, it will establish procedures to distribute such rights and enable you to exercise the rights upon your payment of applicable fees, charges and expenses incurred by the depositary and taxes and/or other governmental charges. The Depositary shall not be obliged to make available to you a method to exercise such rights to subscribe for Class A ordinary shares (rather than ADSs). U.S. securities laws may restrict transfers and cancellation of the ADSs represented by shares purchased upon exercise of rights. For example, you may not be able to trade these ADSs freely in the United States. In this case, the depositary may deliver restricted depositary shares that have the same terms as the ADSs described in this section except for changes needed to put the necessary restrictions in place. There can be no assurance that you will be given the opportunity to exercise rights on the same terms and conditions as the holders of Class A ordinary shares or be able to exercise such rights.

Other Distributions.  Subject to receipt of timely notice, as described in the deposit agreement, from us with the request to make any such distribution available to you, and provided the depositary has determined such distribution is lawful and reasonably practicable and feasible and in accordance with the terms of the deposit agreement, the depositary will distribute to you anything else we distribute on deposited securities by any means it may deem practicable, upon your payment of applicable fees, charges and expenses incurred by the depositary and taxes and/or other governmental charges. If any of the conditions above are not met, the depositary will endeavor to sell, or cause to be sold, what we distributed and distribute the net proceeds in the same way as it does with cash; or, if it is unable to sell such property, the depositary may dispose of such property in any way it deems reasonably practicable under the circumstances for nominal or no consideration, such that you may have no rights to or arising from such property.

        The depositary is not responsible if it decides that it is unlawful or impractical to make a distribution available to any ADS holders. We have no obligation to register ADSs, shares, rights or other securities under the Securities Act. We also have no obligation to take any other action to permit the distribution of ADSs, shares, rights or anything else to ADS holders. This means that you may not receive the distributions we make on our shares or any value for them if we and/or the depositary determines that it is illegal or not practicable for us or the depositary to make them available to you.

Deposit, Withdrawal and Cancellation

How are ADSs issued?

        The depositary will deliver ADSs if you or your broker deposit Class A ordinary shares or evidence of rights to receive Class A ordinary shares with the custodian. Upon payment of its fees and expenses and of any taxes or charges, such as stamp taxes or stock transfer taxes or fees, the depositary will register the appropriate number of ADSs in the names you request and will deliver the ADSs to or upon the order of the person or persons entitled thereto.

How do ADS holders cancel an American Depositary Share?

        You may turn in your ADSs at the depositary's corporate trust office or by providing appropriate instructions to your broker. Upon payment of its fees and expenses and of any taxes or charges, such as stamp taxes or stock transfer taxes or fees, the depositary will deliver the Class A ordinary shares and any other deposited securities underlying the ADSs to you or a person you designate at the office of the custodian. Or, at your request, risk and expense, the depositary will deliver the deposited securities at its corporate trust office, to the extent permitted by law.

How do ADS holders interchange between Certificated ADSs and Uncertificated ADSs?

        You may surrender your ADR to the depositary for the purpose of exchanging your ADR for uncertificated ADSs. The depositary will cancel that ADR and will send you a statement confirming that you are the owner of uncertificated ADSs. Alternatively, upon receipt by the depositary of a proper instruction from a holder of uncertificated ADSs requesting the exchange of uncertificated ADSs for certificated ADSs, the depositary will execute and deliver to you an ADR evidencing those ADSs.

Voting Rights

How do you vote?

        You may instruct the depositary to vote the Class A ordinary shares or other deposited securities underlying your ADSs at any meeting at which you are entitled to vote pursuant to any applicable law, the provisions of our memorandum and articles of association, and the provisions of or governing the deposited securities. Otherwise, you could exercise your right to vote directly if you withdraw the Class A ordinary shares. However, you may not know about the meeting sufficiently enough in advance to withdraw the Class A ordinary shares.

        If we ask for your instructions and upon timely notice from us by regular, ordinary mail delivery, or by electronic transmission, as described in the deposit agreement, the depositary will notify you of the upcoming meeting at which you are entitled to vote pursuant to any applicable law, the provisions of our memorandum and articles of association, and the provisions of or governing the deposited securities, and arrange to deliver our voting materials to you. The materials will include or reproduce (a) such notice of meeting or solicitation of consents or proxies; (b) a statement that the ADS holders at the close of business on the ADS record date will be entitled, subject to any applicable law, the provisions of our memorandum and articles of association, and the provisions of or governing the deposited securities, to instruct the depositary as to the exercise of the voting rights, if any, pertaining to the Class A ordinary shares or other deposited securities represented by such holder's ADSs; and (c) a brief statement as to the manner in which such instructions may be given or deemed given in accordance with the second to last sentence of this paragraph if no instruction is received, to the depositary to give a discretionary proxy to a person designated by us. Voting instructions may be given only in respect of a number of ADSs representing an integral number of Class A ordinary shares or other deposited securities. For instructions to be valid, the depositary must receive them in writing on or before the date specified. The depositary will try, as far as practical, subject to applicable law and the provisions of our memorandum and articles of association, to vote or to have its agents vote the Class A ordinary shares or other deposited securities (in person or by proxy) as you instruct. The depositary will only vote or attempt to vote as you instruct. If we timely requested the depositary to solicit your instructions but no instructions are received by the depositary from an owner with respect to any of the deposited securities represented by the ADSs of that owner on or before the date established by the depositary for such purpose, the depositary shall deem that owner to have instructed the depositary to give a discretionary proxy to a person designated by us with respect to such deposited securities, and the depositary shall give a discretionary proxy to a person designated by us to vote such deposited securities. However, no such instruction shall be deemed given and no such discretionary proxy shall be given with respect to any matter if we inform the depositary we do not wish such proxy given, substantial opposition exists or the matter materially and adversely affects the rights of holders of the Class A ordinary shares.

        We cannot assure you that you will receive the voting materials in time to ensure that you can instruct the depositary to vote the Class A ordinary shares underlying your ADSs. In addition, there can be no assurance that ADS holders and beneficial owners generally, or any holder or beneficial

owner in particular, will be given the opportunity to vote or cause the custodian to vote on the same terms and conditions as the holders of our Class A ordinary shares.

        The depositary and its agents are not responsible for failing to carry out voting instructions or for the manner of carrying out voting instructions. This means that you may not be able to exercise your right to vote and you may have no recourse if the Class A ordinary shares underlying your ADSs are not voted as you requested.

        In order to give you a reasonable opportunity to instruct the depositary as to the exercise of voting rights relating to deposited securities, if we request the depositary to act, we will give the depositary notice of any such meeting and details concerning the matters to be voted at least 30 business days in advance of the meeting date.

Compliance with Regulations

        Each ADS holder and beneficial owner shall (a) provide such information as we or the depositary may request pursuant to law, including, without limitation, relevant Cayman Islands law, any applicable law of the United States of America, our memorandum and articles of association, any resolutions of our Board of Directors adopted pursuant to such memorandum and articles of association, the requirements of any markets or exchanges upon which the Class A ordinary shares, ADSs or ADRs are listed or traded, or to any requirements of any electronic book-entry system by which the ADSs or ADRs may be transferred, regarding the capacity in which they own or owned ADRs, the identity of any other persons then or previously interested in such ADRs and the nature of such interest, and any other applicable matters, and (b) be bound by and subject to applicable provisions of the laws of the Cayman Islands, our memorandum and articles of association, and the requirements of any markets or exchanges upon which the ADSs, ADRs or Class A ordinary shares are listed or traded, or pursuant to any requirements of any electronic book-entry system by which the ADSs, ADRs or Class A ordinary shares may be transferred, to the same extent as if such ADS holder or beneficial owner held Class A ordinary shares directly, in each case irrespective of whether or not they are ADS holders or beneficial owners at the time such request is made.

Disclosure of Interests

        Each ADS holder and beneficial owner shall comply with our requests pursuant to Cayman Islands law, the rules and requirements of the Nasdaq Global Select Market and any other stock exchange on which the Class A ordinary shares are, or will be, registered, traded or listed or our memorandum and articles of association, which requests are made to provide information, inter alia, as to the capacity in which such ADS holder or beneficial owner owns ADS and regarding the identity of any other person interested in such ADS and the nature of such interest and various other matters, whether or not they are ADS holders or beneficial owners at the time of such requests.

Table of Contents

        The depositary fees payable upon the issuance and cancellation of ADSs are typically paid to the depositary bank by the brokers (on behalf of their clients) receiving the newly issued ADSs from the depositary bank and by the brokers (on behalf of their clients) delivering the ADSs to the depositary bank for cancellation. The brokers in turn charge these fees to their clients. Depositary fees payable in connection with distributions of cash or securities to ADS holders and the depositary services fee are charged by the depositary bank to the holders of record of ADSs as of the applicable ADS record date.

        The depositary fees payable for cash distributions are generally deducted from the cash being distributed or by selling a portion of distributable property to pay the fees. In the case of distributions other than cash (i.e., share dividends, rights), the depositary bank charges the applicable fee to the ADS record date holders concurrent with the distribution. In the case of ADSs registered in the name of the investor (whether certificated or uncertificated in direct registration), the depositary bank sends invoices to the applicable record date ADS holders. In the case of ADSs held in brokerage and custodian accounts (via DTC), the depositary bank generally collects its fees through the systems provided by DTC (whose nominee is the registered holder of the ADSs held in DTC) from the brokers and custodians holding ADSs in their DTC accounts. The brokers and custodians who hold their clients' ADSs in DTC accounts in turn charge their clients' accounts the amount of the fees paid to the depositary banks.

        In the event of refusal to pay the depositary fees, the depositary bank may, under the terms of the deposit agreement, refuse the requested service until payment is received or may set off the amount of the depositary fees from any distribution to be made to the ADS holder.

        The depositary may make payments to us or reimburse us for certain costs and expenses, by making available a portion of the ADS fees collected in respect of the ADR program or otherwise, upon such terms and conditions as we and the depositary bank agree from time to time.

Payment of Taxes

        You will be responsible for any taxes or other governmental charges payable, or which become payable, on your ADSs or on the deposited securities represented by any of your ADSs. The depositary may refuse to register or transfer your ADSs or allow you to withdraw the deposited securities represented by your ADSs until such taxes or other charges are paid. It may apply payments owed to you or sell deposited securities represented by your ADSs to pay any taxes owed and you will remain liable for any deficiency. If the depositary sells deposited securities, it will, if appropriate, reduce the number of ADSs to reflect the sale and pay to you any net proceeds, or send to you any property, remaining after it has paid the taxes. You agree to indemnify us, the depositary, the custodian and each of our and their respective agents, directors, employees and affiliates for, and hold each of them harmless from, any claims with respect to taxes (including applicable interest and penalties thereon) arising from any refund of taxes, reduced rate of withholding at source or other tax benefit obtained for you. Your obligations under this paragraph shall survive any transfer of ADRs, any surrender of ADRs and withdrawal of deposited securities or the termination of the deposit agreement.

Amendment and Termination

How may the deposit agreement be amended?

        We may agree with the depositary to amend the deposit agreement and the form of ADR without your consent for any reason. If an amendment adds or increases fees or charges, except for taxes and other governmental charges or expenses of the depositary for registration fees, facsimile costs, delivery charges or similar items, including expenses incurred in connection with foreign exchange control regulations and other charges specifically payable by ADS holders under the deposit agreement, or materially prejudices a substantial existing right of ADS holders, it will not become effective for outstanding ADSs until 30 days after the depositary notifies ADS holders of the amendment. At the time an amendment becomes effective, you are considered, by continuing to hold your ADSs, to agree to the amendment and to be bound by the ADRs and the deposit agreement as amended . If any new laws are adopted which would require the deposit agreement to be amended in order to comply therewith, we and the depositary may amend the deposit agreement in accordance with such laws and such amendment may become effective before notice thereof is given to ADS holders.

How may the deposit agreement be terminated?

        The depositary will terminate the deposit agreement if we ask it to do so, in which case the depositary will give notice to you at least 90 days prior to termination. The depositary may also terminate the deposit agreement if the depositary has told us that it would like to resign, or if we have removed the depositary, and in either case we have not appointed a new depositary within 90 days. In either such case, the depositary must notify you at least 30 days before termination.

        After termination, the depositary and its agents will do the following under the deposit agreement but nothing else: collect distributions on the deposited securities, sell rights and other property and deliver Class A ordinary shares and other deposited securities upon cancellation of ADSs after payment of any fees, charges, taxes or other governmental charges. Six months or more after the date of termination, the depositary may sell any remaining deposited securities by public or private sale. After that, the depositary will hold the money it received on the sale, as well as any other cash it is holding under the deposit agreement, for the pro rata benefit of the ADS holders that have not surrendered their ADSs. It will not invest the money and has no liability for interest. After such sale, the depositary's only obligations will be to account for the money and other cash. After termination, we shall be discharged from all obligations under the deposit agreement except for our obligations to the depositary thereunder.

Books of Depositary

        The depositary will maintain ADS holder records at its depositary office. You may inspect such records at such office during regular business hours but solely for the purpose of communicating with other holders in the interest of business matters relating to our company, the ADRs and the deposit agreement.

        The depositary will maintain facilities in the Borough of Manhattan, The City of New York to record and process the issuance, cancellation, combination, split-up and transfer of ADRs.

        These facilities may be closed at any time or from time to time when such action is deemed necessary or advisable by the depositary in connection with the performance of its duties under the deposit agreement or at our reasonable written request.

        In the deposit agreement, we and the depositary agree to indemnify each other under certain circumstances.

Jurisdiction and Arbitration

        The laws of the State of New York govern the deposit agreement and the ADSs and we have agreed with the depositary that the federal or state courts in the City of New York shall have exclusive jurisdiction to hear and determine any dispute arising from or in connection with the deposit agreement and that the depositary will have the right to refer any claim or dispute arising from the relationship created by the deposit agreement to arbitration in accordance with the Commercial Arbitration Rules of the American Arbitration Association. The arbitration provisions of the deposit agreement do not preclude you from pursuing claims under the Securities Act or the Exchange Act in federal courts.

Jury Trial Waiver

        The deposit agreement provides that each party to the deposit agreement (including each holder, beneficial owner and holder of interests in the ADRs) irrevocably waives, to the fullest extent permitted by applicable law, any right it may have to a trial by jury in any lawsuit or proceeding against us or the depositary arising out of or relating to our shares, the ADSs or the deposit agreement, including any claim under the U.S. federal securities laws. If we or the depositary opposed a jury trial demand based on the waiver, the court would determine whether the waiver was enforceable based on the facts and circumstances of that case in accordance with the applicable law. By agreeing to this jury trial waiver provision, however, holders or beneficial owners of ADSs will not be deemed to have waived our or the depositary's compliance with the U.S. federal securities laws and the rules and regulations promulgated thereunder.

Requirements for Depositary Actions

        Before the depositary will issue, deliver or register a transfer of an ADS, split-up, subdivide or combine ADSs, make a distribution on an ADS, or permit withdrawal of Class A ordinary shares, the depositary may require:

•

payment of stock transfer or other taxes or other governmental charges and transfer or registration fees charged by third parties for the transfer of any Class A ordinary shares or other deposited securities and payment of the applicable fees, expenses and charges of the depositary;



•

satisfactory proof of the identity and genuineness of any signature or any other matters contemplated in the deposit agreement; and



•

compliance with (A) any laws or governmental regulations relating to the execution and delivery of ADRs or ADSs or to the withdrawal or delivery of deposited securities and (B) such reasonable regulations and procedures as the depositary may establish, from time to time, consistent with the deposit agreement and applicable laws, including presentation of transfer documents.

        The depositary may refuse to issue and deliver ADSs or register transfers of ADSs generally when the register of the depositary or our transfer books are closed or at any time if the depositary or we determine that it is necessary or advisable to do so.

Your Right to Receive the Shares Underlying Your ADSs

        You have the right to cancel your ADSs and withdraw the underlying Class A ordinary shares at any time except:

•

when temporary delays arise because: (1) the depositary has closed its transfer books or we have closed our transfer books; (2) the transfer of Class A ordinary shares is blocked to permit voting at a shareholders' meeting; or (3) we are paying a dividend on our Class A ordinary shares;



•

when you owe money to pay fees, taxes and similar charges;



•

when it is necessary to prohibit withdrawals in order to comply with any laws or governmental regulations that apply to ADSs or to the withdrawal of ordinary shares or other deposited securities, or other circumstances specifically contemplated by Section I.A.(l) of the General Instructions to Form F-6 (as such General Instructions may be amended from time to time); or



•

for any other reason if the depositary or we determine, in good faith, that it is necessary or advisable to prohibit withdrawals.

        The depositary shall not knowingly accept for deposit under the deposit agreement any Class A ordinary shares or other deposited securities required to be registered under the provisions of the Securities Act, unless a registration statement is in effect as to such ordinary shares.

Direct Registration System

        In the deposit agreement, all parties to the deposit agreement acknowledge that the DRS and Profile Modification System, or Profile, will apply to uncertificated ADSs upon acceptance thereof to DRS by DTC. DRS is the system administered by DTC pursuant to which the depositary may register the ownership of uncertificated ADSs, which ownership shall be evidenced by periodic statements issued by the depositary to the ADS holders entitled thereto. Profile is a required feature of DRS which allows a DTC participant, claiming to act on behalf of an ADS holder, to direct the depositary to register a transfer of those ADSs to DTC or its nominee and to deliver those ADSs to the DTC account of that DTC participant without receipt by the depositary of prior authorization from the ADS holder to register such transfer.

General

        We may sell the debt securities, including original issue discount securities, at par or at greater than de minimis discount below their stated principal amount. Unless we inform you otherwise in a prospectus supplement, we may issue additional debt securities of a particular series without the consent of the holders of the debt securities of such series outstanding at the time of issuance. Any such additional debt securities, together with all other outstanding debt securities of that series, will constitute a single series of debt securities under the indenture. Such additional debt securities will have the same terms and conditions as the applicable series of debt securities in all respects (or in all respects except for the issue date, the issue price or the first payment of interest), and will vote together as one class on all matters with respect to such series of debt securities. We shall not issue any additional debt securities with the same CUSIP, ISIN or other identifying number as outstanding debt securities issued hereunder unless the additional debt securities are fungible with such outstanding debt securities of the relevant series for U.S. federal income tax or securities law purposes. In addition, we

30

---

Table of Contents

will describe in the applicable prospectus supplement, material U.S. federal tax considerations. Unless we inform you otherwise in the applicable prospectus supplement, the debt securities will not be listed on any securities exchange.

Form, Exchange and Transfer

        The debt securities will be issued in fully registered form without interest coupons and, unless otherwise indicated in the applicable prospectus supplement, in minimum denominations of US$1,000 and integral multiples of US$1,000 in excess thereof.

        The entity performing the role of maintaining the list of registered holders is called the "registrar." The registrar acts as our agent for registering debt securities in the names of holders and transferring registered debt securities. You may exchange or transfer your registered debt securities at the specified office of the registrar. We may also arrange for additional registrars, and may change registrars. We may also choose to act as our own registrar.

        You will not be required to pay a service charge for any registration of transfer or exchange of debt securities, but you may be required to pay any tax or other governmental charge associated with the registration of transfer or exchange. The registration of transfer or exchange of a registered debt security will only be made if you have duly endorsed the debt security or provided the registrar with a written instrument of transfer satisfactory in form to the registrar.

Payment and Paying Agents

        If your debt securities are in definitive registered form, we will pay interest to you if you are listed in the registrar's records as a direct holder at the close of business on a particular day in advance of each due date for interest, even if you no longer own the debt securities on the interest due date. That particular day is called the "record date" and will be stated in the applicable prospectus supplement.

        We will pay interest, principal, additional amounts and any other money due on global registered debt securities pursuant to the applicable procedures of the depositary or, if the debt securities are not in global form, at offices maintained for that purpose in New York, New York. These offices are called "paying agents." We may also choose to pay interest by mailing checks. We may also arrange for additional payment agents, and may change these agents, including our use of the trustee's corporate trust office. We may also choose to act as our own paying agent.

        Regardless of who acts as paying agent, all money that we pay as principal, premium or interest to a paying agent, or then held by us in trust, that remains unclaimed at the end of two years after the amount is due to direct holders will be repaid to us, or if then held by us, discharged from trust. After that two-year period, direct holders may look only to us for payment and not to the trustee, any other paying agent or anyone else.

        Street name and other indirect holders should consult their banks or brokers for information on how they will receive payments.

Payment of Additional Amounts

        All payments of principal, premium and interest made by or on behalf of us in respect of the debt securities of each series will be made without withholding or deduction for, or on account of, any present or future taxes, duties, assessments or governmental charges of whatever nature ("Taxes") imposed or levied by or within Bermuda, the British Virgin Islands, Cayman Islands, Hong Kong, the PRC or any jurisdiction where we or our paying agent are otherwise considered by a taxing authority to be a resident for tax purposes (in each case, including any political subdivision or any authority therein or thereof having power to tax) (the "Relevant Jurisdiction"), unless such withholding or deduction of such Taxes is required by law. If we are required to make such withholding or deduction, we will pay

Table of Contents

such additional amounts ("Additional Amounts") as will result in receipt by each holder of any debt securities of such amounts as would have been received by such holder had no such withholding or deduction of such Taxes been required, except that no such Additional Amounts shall be payable:

          (i)  in respect of any such Taxes that would not have been imposed, deducted or withheld but for the existence of any connection (whether present or former) between the holder or beneficial owner of a debt security and the Relevant Jurisdiction other than merely holding such debt security or receiving principal, premium (if any) or interest in respect thereof (including such holder or beneficial owner being or having been a national, domiciliary or resident of such Relevant Jurisdiction or treated as a resident thereof or being or having been physically present or engaged in a trade or business therein or having or having had a permanent establishment therein);

         (ii)  in respect of any debt security presented for payment (where presentation is required) more than 30 days after the relevant date, except to the extent that the holder thereof would have been entitled to such Additional Amounts on presenting the same for payment on the last day of such 30-day period. For this purpose, the "relevant date" in relation to any debt security means the later of (a) the due date for such payment or (b) the date such payment was made or duly provided for;

        (iii)  in respect of any Taxes that would not have been imposed, deducted or withheld but for a failure of the holder or beneficial owner of a debt security to comply with a timely request by us addressed to the holder or beneficial owner to provide information concerning such holder's or beneficial owner's nationality, residence, identity or connection with any Relevant Jurisdiction, if and to the extent that due and timely compliance with such request is required under the tax laws of such jurisdiction in order to reduce or eliminate any withholding or deduction as to which Additional Amounts would have otherwise been payable to such holder;

        (iv)  in respect of any Taxes imposed as a result of a debt security being presented for payment (where presentation is required) in the Relevant Jurisdiction, unless such debt security could not have been presented for payment elsewhere;

         (v)  in respect of any estate, inheritance, gift, sale, transfer, personal property or similar Taxes;

        (vi)  to any holder of a debt security that is a fiduciary, partnership or person other than the sole beneficial owner of any payment to the extent that such payment would be required to be included in the income under the laws of a Relevant Jurisdiction, for tax purposes, of a beneficiary or settlor with respect to the fiduciary, or a member of that partnership or a beneficial owner who would not have been entitled to such Additional Amounts had that beneficiary, settlor, partner or beneficial owner been the holder thereof;

       (vii)  with respect to any withholding or deduction that is imposed in connection with Sections 1471-1474 of the Internal Revenue Code of 1986, as amended, and U.S. Treasury regulations thereunder ("FATCA"), any intergovernmental agreement between the United States and any other jurisdiction implementing or relating to FATCA or any non-U.S. law, regulation or guidance enacted or issued with respect thereto;

      (viii)  any such Taxes payable otherwise than by deduction or withholding from payments under or with respect to any debt security; or

        (ix)  any combination of Taxes referred to in the preceding items (i) through (viii) above.

        In the event that any withholding or deduction for or on account of any Taxes is required and Additional Amounts are payable with respect thereto, at least 10 business days prior to each date of payment of principal of, premium (if any) or interest on the debt securities of any series, we will furnish to the trustee and the paying agent, if other than the trustee, an officers' certificate specifying the amount required to be withheld or deducted on such payments to such holders, certifying that we shall pay such amounts required to be withheld to the appropriate governmental authority and

32

---

Table of Contents

certifying to the fact that the Additional Amounts will be payable and the amounts so payable to each holder, and that we will pay to the trustee or such paying agent the Additional Amounts required to be paid; provided that no such officers' certificate will be required prior to any date of payment of principal of, premium (if any) or interest on such debt securities if there has been no change with respect to the matters set forth in a prior officers' certificate. The trustee and each paying agent shall be entitled to rely on the fact that any officers' certificate contemplated by this paragraph has not been furnished as evidence of the fact that no withholding or deduction for or on account of any Taxes is required. We covenant to indemnify the trustee and any paying agent for and to hold them harmless against any loss, liability or reasonable expenses without fraudulent activity, gross negligence or willful misconduct on their part arising out of or in connection with actions taken or omitted by any of them in reliance on any such officers' certificate furnished pursuant to this paragraph or on the fact that any officers' certificate contemplated by this paragraph has not been furnished.

        If we or our successor is required to make any deduction or withholding from any payments or deliveries with respect to the notes, it shall deliver to the trustee, the paying agent and the holders official tax receipts evidencing the remittance to the relevant tax authorities of the amounts so withheld or deducted.

        Whenever there is mentioned, in any context, the payment of principal, premium or interest in respect of any debt security, such mention shall be deemed to include the payment of Additional Amounts provided for in the indenture, to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof pursuant to the indenture.

        The foregoing provisions shall apply in the same manner with respect to the jurisdiction in which any successor Person to us or its paying agent is organized or resident for tax purposes or any authority therein or thereof having the power to tax (a "Successor Jurisdiction"), substituting such Successor Jurisdiction for the Relevant Jurisdiction.

        Our obligation to make payments of Additional Amounts under the terms and conditions described above will survive any termination, defeasance or discharge of the indenture.

Tax Redemption

        Each series of debt securities may be redeemed at any time, at our option, in whole but not in part, upon written notice as described below, at a redemption price equal to 100% of the principal amount thereof, together with accrued and unpaid interest, if any, to, but not including, the date fixed for redemption, if (i) as a result of any change in, or amendment to, the laws or regulations of the Relevant Jurisdiction (or, in the case of Additional Amounts payable by a successor Person to us, the applicable Successor Jurisdiction), or any change in the official application or official interpretation of such laws or regulations, which change or amendment becomes effective on or after the issue date of the applicable series of debt securities (or, in the case of Additional Amounts payable by a successor Person to us, the date on which such successor Person to us became a successor to us pursuant to the applicable provisions of the indenture) (a "Tax Change"), we or any such successor Person to us is, or would be, obligated to pay Additional Amounts upon the next payment of principal, premium (if any) or interest in respect of such debt securities and (ii) such obligation cannot be avoided by us or any such successor Person to us taking reasonable measures available to it, provided that changing our or such successor Person's jurisdiction is not a reasonable measure for purposes of this section.

        Prior to the giving of any notice of redemption of debt securities pursuant to the foregoing, we or any such successor Person to us shall deliver to the trustee (i) a notice of such redemption election, (ii) an opinion of external legal counsel or an opinion of an independent tax consultant to the effect that we or any such successor Person to us is, or would become, obligated to pay such Additional Amounts as the result of a Tax Change and (iii) an officers' certificate from us or any such successor Person to us, stating that such amendment or change has occurred, describing the facts leading thereto

33

Table of Contents

and stating that such requirement cannot be avoided by us or any such successor Person to us taking reasonable measures available to it. The trustee shall be entitled to rely conclusively upon such certificate and opinion as sufficient evidence of the conditions precedent described above, in which event it shall be conclusive and binding on the relevant holders.

        Notice of redemption of debt securities as provided above shall be given to the holders not less than 30 nor more than 60 days prior to the date fixed for redemption; provided that no such notice of redemption shall be given earlier than 90 days prior to the earliest date on which we or any such successor Person to us would be required to pay Additional Amounts if a payment in respect of such debt securities was then due. Notice having been given, the debt securities of that series shall become due and payable on the date fixed for redemption and will be paid at the redemption price, together with accrued and unpaid interest, if any, to, but not including, the date fixed for redemption, at the place or places of payment and in the manner specified in that series of the debt securities. From and after the redemption date, if moneys for the redemption of such debt securities shall have been made available as provided in the indenture for redemption on the redemption date, the debt securities of such series shall cease to bear interest, and the only right of the holders of such debt securities shall be to receive payment of the redemption price and accrued and unpaid interest, if any, to, but not including, the date fixed for redemption.

Open Market Purchases

        We or any of our Controlled Entities may, in accordance with all applicable laws and regulations, at any time purchase the debt securities issued under the indenture in the open market or otherwise at any price, so long as such purchase does not otherwise violate the terms of the indenture. The debt securities so purchased, while held by or on behalf of us or any of our Controlled Entities, shall not be deemed to be outstanding for the purposes of determining whether the holders of the requisite principal amount of outstanding debt securities have given any request, demand, authorization, direction, notice, consent or waiver hereunder.

Modification and Waiver

        The indenture contains provisions permitting us and the trustee, without the consent of the holders of the applicable series of debt securities, to execute supplemental indentures for certain enumerated purposes in the indenture and, with the consent of the holders of not less than a majority in aggregate principal amount of the applicable series of debt securities then outstanding under the indenture, to add, change, eliminate or modify in any way the provisions of the indenture or any supplemental indentures or to change or modify in any manner the rights of the holders of such debt securities. We and the trustee may not, however, without the consent of each holder of the debt securities of the applicable series affected thereby:

          (i)  change the Stated Maturity of any debt security;

         (ii)  reduce the principal amount of, payments of interest on or stated time for payment of interest on any debt security;

        (iii)  change any obligation of ours to pay Additional Amounts with respect to any debt security;

        (iv)  change the currency of payment of the principal of, premium (if any) or interest on any debt security;

         (v)  reduce the amount of the principal of an original issue discount security that would be due and payable upon a declaration of acceleration of the maturity thereof;

        (vi)  impair the right to institute suit for the enforcement of any payment due on or with respect to any debt security;

34

Table of Contents

       (vii)  reduce the above stated percentage of outstanding debt securities necessary to modify or amend the indenture;

      (viii)  reduce the percentage of the aggregate principal amount of outstanding debt securities of that series necessary for waiver of compliance with certain provisions of the indenture or for waiver of certain defaults;

        (ix)  modify the provisions of the indenture with respect to modification and waiver;

         (x)  amend, change or modify any provision of the indenture or the related definition affecting the ranking of any series of debt securities in a manner which adversely affects the holders of such debt securities; or

        (xi)  reduce the amount of the premium payable upon the redemption or repurchase of any series of debt securities or change the time at which any series of debt securities may be redeemed or repurchased as described above under "—Tax Redemption" or as described in the applicable prospectus supplement.

        The holders of not less than a majority in principal amount of the debt securities of any series then outstanding may on behalf of all holders of the debt securities of that series waive any existing or past Default or Event of Default and its consequences under the indenture, except a continuing Default or Event of Default (i) in the payment of principal of, premium (if any) or interest on (or Additional Amount payable in respect of), the debt securities of such series then outstanding, in which event the consent of all holders of the debt securities of such series then outstanding affected thereby is required, or (ii) in respect of a covenant or provision which under the indenture cannot be modified or amended without the consent of the holder of each debt security of such series then outstanding affected thereby. Any such waivers will be conclusive and binding on all holders of that series of debt securities, whether or not they have given consent to such waivers, and on all future holders of such debt securities, whether or not notation of such waivers is made upon such debt securities. Any instrument given by or on behalf of any holder of a debt security of that series in connection with any consent to any such waiver will be irrevocable once given and will be conclusive and binding on all subsequent holders of such debt security.

        Notwithstanding the foregoing, without the consent of any holder of the securities, we and the trustee may amend the indenture and the relevant debt securities to, among other things:

          (i)  cure any ambiguity, omission, defect or inconsistency contained in the indenture or in any supplemental indenture; provided, however, that such amendment does not materially and adversely affect the rights of holders;

         (ii)  evidence the succession of another corporation to our company, or successive successions, and the assumption by such successor of the covenants and obligations of our company contained in the debt securities of one or more series and in this indenture or any supplemental indenture;

        (iii)  comply with the rules of any applicable depositary;

        (iv)  secure any series of debt securities;

         (v)  add to the covenants and agreements of our company, to be observed thereafter and during the period, if any, in such supplemental indenture or indentures expressed, and to add Events of Default, in each case for the protection or benefit of the holders of all or any series of the debt securities (and if such covenants, agreements and Events of Default are to be for the benefit of fewer than all series of debt securities, stating that such covenants, agreements and Events of Default are expressly being included for the benefit of such series as shall be identified therein), or to surrender any right or power herein conferred upon our company;

Table of Contents

        (vi)  make any change in any series of debt securities that does not adversely affect the legal rights under the indenture of any holder of such debt securities in any material respect;

       (vii)  evidence and provide for the acceptance of an appointment under the indenture of a successor trustee; provided that the successor trustee is otherwise qualified and eligible to act as such under the terms thereof;

      (viii)  conform the text of the indenture or any series of the debt securities to any provision of this "Description of Debt Securities" to the extent that such provision in this prospectus was intended to be a verbatim recitation of a provision of the indenture or such series of the debt securities as evidenced by an officers' certificate;

        (ix)  make any amendment to the provisions of the indenture relating to the transfer and legending of debt securities as permitted by the indenture, including, but not limited to, facilitating the issuance and administration of any series of the debt securities or, if incurred in compliance with the indenture, additional debt securities; provided, however, that (A) compliance with the indenture as so amended would not result in any series of the debt securities being transferred in violation of the Securities Act or any applicable securities law and (B) such amendment does not materially and adversely affect the rights of holders to transfer debt securities;

         (x)  change or eliminate any of the provisions of the indenture; provided that any such change or elimination shall become effective only when there is no outstanding debt security of any series created prior to the execution of such supplemental indenture that is entitled to the benefit of such provision and as to which such supplemental indenture would apply;

        (xi)  make any amendment to the indenture necessary to qualify the indenture under the Trust Indenture Act;

       (xii)  add guarantors or co-obligors with respect to any series of debt securities; and

      (xiii)  establish the form and terms of debt securities of any series as permitted under the indenture, or to provide for the issuance of additional debt securities in accordance with the limitations set forth in the indenture, or to add to the conditions, limitations or restrictions on the authorized amount, terms or purposes of issue, authentication or delivery of the debt securities of any series, as herein set forth, or other conditions, limitations or restrictions thereafter to be observed.

        The consent of the holders is not necessary under the indenture to approve the particular form of any proposed amendment, supplement or waiver. It is sufficient if such consent approves the substance of the proposed amendment or supplement. A consent to any amendment, supplement or waiver under the indenture by any holder given in connection with a tender of such holder's debt securities will not be rendered invalid by such tender. After an amendment, supplement or waiver under the indenture becomes effective, we are required to give to the holders a notice briefly describing such amendment, supplement or waiver. However, the failure to give such notice to all the holders, or any defect in the notice will not impair or affect the validity of the amendment, supplement or waiver.

Consolidation, Merger and Sale of Assets

        The indenture provides that we may not consolidate with or merge into any other Person in a transaction in which we are not the surviving entity, or convey, transfer or lease our properties and assets substantially as an entirety to, any Person unless:

          (i)  any Person formed by such consolidation or into which we are merged or to whom we have conveyed, transferred or leased our properties and assets substantially as an entirety is a corporation, partnership, trust or other entity validly existing under the laws of Bermuda, the British Virgin Islands, Cayman Islands or Hong Kong and such Person expressly assumes by indentures supplemental to the indenture all of our obligations under the indenture and the debt securities issued under the indenture,

36

Table of Contents

including the obligation to pay Additional Amounts with respect to any jurisdiction in which it is organized or resident for tax purposes;

         (ii)  immediately after giving effect to the transaction, no Event of Default, and no event which, after notice or lapse of time or both, would become an Event of Default, shall have occurred and be continuing; and

        (iii)  we have delivered to the trustee an officers' certificate and an opinion of external legal counsel, each stating that such consolidation, merger, conveyance, transfer or lease and such supplemental indentures comply with the indenture and that all conditions precedent therein provided for relating to such transaction have been complied with.

Payments for Consent

        We will not, and will not permit any of our Controlled Entities to, directly or indirectly, pay or cause to be paid any consideration to or for the benefit of any holder of debt securities of any series for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of the indenture or the debt securities of such series unless such consideration is offered to be paid and is paid to all holders of the relevant series of debt securities that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or amendment.

Events of Default

        Under the terms of the indenture, each of the following constitutes an Event of Default for a series of debt securities unless, as otherwise stated in the applicable prospectus supplement, it is either inapplicable to a particular series or it is specifically deleted or modified:

          (i)  failure to pay principal or premium in respect of any debt securities of that series by the due date for such payment (whether at Stated Maturity or upon acceleration, repurchase, redemption or otherwise);

         (ii)  failure to pay interest on any debt securities of that series within 30 days after the due date for such payment;

        (iii)  we default in the performance of or breach our obligations under the "—Consolidation, Merger and Sale of Assets" covenant;

        (iv)  we default in the performance of or breach any covenant or agreement in the indenture or under the debt securities of that series (other than a default specified in clause (i), (ii) or (iii) above) and such default or breach continues for a period of 60 consecutive days after written notice by the trustee or the holders of 25% or more in aggregate principal amount of the debt securities of that series;

         (v)  (1) there occurs with respect to any of our indebtedness or indebtedness of any of our "significant subsidiaries," as defined in Article 1, Rule 1-02 of Regulation S-X, whether such indebtedness now exists or shall hereafter be created, (A) an event of default that has resulted in the holder thereof declaring the principal of such indebtedness to be due and payable prior to its stated maturity or (B) a failure to make a payment of principal, interest or premium when due (after giving effect to the expiration of any applicable grace period therefor, a "Payment Default") and (2) the outstanding principal amount of such indebtedness, together with the outstanding principal amount of any other indebtedness of such Persons under which there has been a Payment Default or the maturity of which has been so accelerated, is equal to or exceeds US$60,000,000, and in each case, such indebtedness is not discharged, or such acceleration is not otherwise cured or rescinded, within 30 days;

        (vi)  one or more final judgments or orders for the payment of money are rendered against us or any of our significant subsidiaries, as defined in Article 1, Rule 1-02 of Regulation S-X, and are not

       (vii)  the entry by a court having jurisdiction in the premises of (i) a decree or order for relief in respect of us or any of our significant subsidiaries, as defined in Article 1, Rule 1-02 of Regulation S-X, in an involuntary case or proceeding under any applicable bankruptcy, insolvency or other similar law or (ii) a decree or order adjudging us or any of our significant subsidiaries bankrupt or insolvent, or approving as final and nonappealable a petition seeking reorganization, arrangement, adjustment, or composition of or in respect of us or any of our significant subsidiaries under any applicable bankruptcy, insolvency or other similar law, or appointing a custodian, receiver, liquidator, assignee, trustee, sequestrator, or other similar official of us or any of our significant subsidiaries or of any substantial part of their respective property, or ordering the winding up or liquidation of their respective affairs (or any similar relief granted under any foreign laws), and in any such case the continuance of any such decree or order for relief or any such other decree or order unstayed and in effect for a period of 90 consecutive calendar days;

      (viii)  the commencement by us or any of our significant subsidiaries, as defined in Article 1, Rule 1-02 of Regulation S-X, of a voluntary case or proceeding under any applicable federal, state or foreign bankruptcy, insolvency or other similar law or of any other case or proceeding to be adjudicated bankrupt or insolvent, or the consent by us or any significant subsidiary to the entry of a decree or order for relief in respect of us or any of our significant subsidiaries in an involuntary case or proceeding under any applicable bankruptcy, insolvency or other similar law or the commencement of any bankruptcy or insolvency case or proceeding against us or any significant subsidiary, or the filing by us or any significant subsidiary of a petition or answer or consent seeking reorganization or relief with respect to us or any of our significant subsidiaries under any applicable bankruptcy, insolvency or other similar law, or the consent by us or any significant subsidiary to the filing of such petition or to the appointment of or taking possession by a custodian, receiver, liquidator, assignee, trustee, sequestrator, or other similar official of us or any of our significant subsidiaries or of any substantial part of their respective property pursuant to any such law, or the making by us or any of our significant subsidiaries of a general assignment for the benefit of creditors in respect of any indebtedness as a result of an inability to pay such indebtedness as it becomes due, or the admission by us or any of our significant subsidiaries in writing of our inability to pay our debts generally as they become due, or the taking of corporate action by us or any of our significant subsidiaries that resolves to commence any such action;

        (ix)  the debt securities of that series or the indenture is or becomes or is claimed by us to be unenforceable, invalid or ceases to be in full force and effect otherwise than is permitted by the indenture; and

         (x)  any other event of default described in the applicable prospectus supplement.

        However, a default under clause (iv) of the preceding paragraph will not constitute an Event of Default until the trustee or the holders of 25% in principal amount of the then outstanding debt securities of that series provide written notice to us of the default and we do not cure such default within the time specified in clause (iv) of the preceding paragraph after receipt of such notice.

        If an Event of Default (other than an Event of Default described in clauses (vii) and (viii) above) shall occur and be continuing, either the trustee or the holders of at least 25% in aggregate principal amount of the debt securities of that series then outstanding by written notice as provided in the indenture may, and the trustee, upon instructions from holders of at least 25% in aggregate principal amount of the debt securities of that series then outstanding and subject to receipt of pre-funding, security and/or indemnity to its satisfaction, shall declare the unpaid principal amount of such debt

securities and any accrued and unpaid interest thereon (and any Additional Amount payable in respect thereof) to be due and payable immediately upon receipt of such notice. If an Event of Default in clause (v) above shall occur, the declaration of acceleration of the debt securities shall be automatically annulled if the default triggering such Event of Default pursuant to clause (v) shall be remedied or cured by us or any of our significant subsidiaries, as defined in Article 1, Rule 1-02 of Regulation S-X, or waived by the holders of the relevant indebtedness within 30 days after the declaration of acceleration with respect thereto and if (1) the annulment of the acceleration of the debt securities of that series would not conflict with any judgment or decree of a court of competent jurisdiction and (2) all Events of Default, other than the non-payment of principal, premium (if any) or interest on the debt securities of that series that became due solely because of the acceleration of the debt securities of that series, have been cured or waived. If an Event of Default in clauses (vii) or (viii) above shall occur, the unpaid principal amount of all the debt securities then outstanding and any accrued and unpaid interest thereon will automatically, and without any declaration or other action by the trustee or any holder of such debt securities, become immediately due and payable. After a declaration of acceleration but before a judgment or decree for payment of the money due has been obtained by the trustee, the holders of at least a majority in aggregate principal amount of the debt securities of that series then outstanding may, under certain circumstances, waive all past defaults and rescind and annul such acceleration if (1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction, and (2) all Events of Default, other than the non-payment of principal, premium, if any, or interest on such debt securities that became due solely because of the acceleration of such debt securities, have been cured or waived. For information as to waiver of defaults, see "—Modification and Waiver."

        Subject to the provisions of the indenture relating to the duties of the trustee, in case an Event of Default shall occur and be continuing, the trustee will be under no obligation to exercise any of the trusts or powers vested in it by the indenture at the request, order or direction of any of the holders of debt securities, unless such holders shall have offered to the trustee pre-funding, security and/or indemnity satisfactory to it against the costs, expenses and liabilities which may be incurred therein or thereby. Subject to certain provisions, including those requiring pre-funding, security and/or indemnification of the trustee, the holders of a majority in aggregate principal amount of the debt securities of a series then outstanding will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee. No holder of any debt security of any series will have any right to institute any proceeding, judicial or otherwise, with respect to the indenture or the debt securities, or for the appointment of a receiver or a trustee, or for any other remedy thereunder, unless (i) such holder has previously given to the trustee written notice of a continuing Event of Default with respect to the debt securities of that series, (ii) the holders of at least 25% in aggregate principal amount of the debt securities of that series then outstanding have made written request to the trustee to institute such proceeding, (iii) such holder or holders have offered pre-funding, security and/or indemnity satisfactory to the trustee and (iv) the trustee has failed to institute such proceeding, and has not received from the holders of a majority in aggregate principal amount of the debt securities of that series then outstanding a direction inconsistent with such request, within 60 days after such notice, request and offer. However, such limitations do not apply to a suit instituted by a holder of a debt security for the enforcement of the right to receive payment of the principal of, premium (if any) or interest on such debt security on or after the applicable due date specified in such debt security.

Legal Defeasance and Covenant Defeasance

        The indenture will provide that we may at our option and at any time elect to have all of our obligations discharged with respect to the outstanding debt securities of a series ("Legal Defeasance") except for:

        (1)   the rights of holders of the debt securities of that series that are then outstanding to receive payments in respect of the principal of, or interest or premium on such debt securities when such payments are due from the trust referred to below;

        (2)   our obligations with respect to the debt securities of that series concerning issuing temporary notes, registration of notes, mutilated, destroyed, lost or stolen notes and the maintenance of an office or agency for payment and money for security payments held in trust;

        (3)   the rights, powers, trusts, duties and immunities of the trustee for the debt securities of that series, and our obligations in connection therewith; and

        (4)   the Legal Defeasance and Covenant Defeasance (as defined below) provisions of the indenture for the debt securities of that series.

        The indenture will provide that, we may, at our option and at any time, elect to have our obligations with respect to the outstanding debt securities of a series released with respect to certain covenants (including our obligations under the headings "Consolidation, Merger and Sale of Assets" and "Payments for Consents") that are described in the indenture ("Covenant Defeasance") and thereafter any omission to comply with those covenants will not constitute a Default or Event of Default. In the event Covenant Defeasance occurs, certain events (not including non-payment, bankruptcy, receivership, rehabilitation and insolvency events) described under the caption "—Events of Default" will no longer constitute an Event of Default.

        The indenture will also provide that, in order to exercise either Legal Defeasance or Covenant Defeasance:

        (1)   we must irrevocably deposit with the trustee or the paying agent, in trust, for the benefit of the holders of all debt securities of that series subject to Legal Defeasance or Covenant Defeasance, cash in U.S. dollars, U.S. Government Obligation, or a combination of cash in U.S. dollars and U.S. Government Obligation, in amounts as will be sufficient, in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants to pay the principal of, or interest and premium on such notes that are then outstanding on the Stated Maturity or on the applicable redemption date, as the case may be, and we must specify whether such debt securities are being defeased to maturity or to a particular redemption date;

        (2)   in the case of Legal Defeasance, we must deliver to the trustee an opinion of external legal counsel of recognized standing with respect to U.S. federal income tax matters that is acceptable to the trustee confirming that (a) we have received from, or there has been published by, the Internal Revenue Service a ruling or (b) since the date of the indenture, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such opinion of external legal counsel will confirm that, the beneficial owners of the then outstanding debt securities of that series will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

        (3)   in the case of Covenant Defeasance, we must deliver to the trustee an opinion of external legal counsel of recognized standing with respect to U.S. federal income tax matters that is acceptable to the trustee confirming that the beneficial owners of the then outstanding debt securities of that series will not recognize income, gain or loss for federal income tax purposes as a

Table of Contents

        (a)   all debt securities of that series that have been authenticated, except lost, stolen or destroyed debt securities that have been replaced or paid and notes for whose payment money has been deposited in trust and thereafter repaid to us, have been delivered to the paying agent for cancellation; or

        In addition, we shall deliver an officers' certificate and an opinion of external legal counsel to the trustee stating that all conditions precedent to satisfaction and discharge have been satisfied.

Concerning the Trustee

        The trustee under the indenture is Deutsche Bank Trust Company Americas. Pursuant to the indenture, the trustee will be designated by us as the initial paying and transfer agent and registrar for the debt securities. The corporate trust office of the trustee is currently located at 60 Wall Street, 24th Floor, New York, New York, 10005, Attention: Global Transaction Banking—Pinduoduo.

        The indenture provides that the trustee, except during the continuance of an Event of Default, undertakes to perform such duties and only such duties as are specifically set forth therein. If an Event of Default has occurred and is continuing, the trustee will exercise such of the rights and powers vested in it by the indenture, and use the same degree of care and skill in its exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person's own affairs.

        Whenever the trustee shall have discretion or permissive power in accordance with the indenture or the law, the trustee may decline to exercise the same in the absence of approval by the holders and shall have no obligation to exercise the same unless it has received pre-funding, been indemnified and/or provided with security to its satisfaction against all actions, proceedings, claims, actions or demands to which it may render itself liable and all costs, damages, charges, expenses and liabilities which it may incur by so doing. The trustee in its various capacities shall in no event be responsible for special, indirect, punitive or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit, goodwill or opportunity), whether or not foreseeable, even if the trustee has been advised of the possibility of such loss or damage and regardless of the form of action.

        Subject to the terms of the indenture and the Trust Indenture Act, the trustee is permitted to engage in other transactions with our company and its affiliates and can profit therefrom without being obliged to account for such profit; and the trustee shall not be under any obligation to monitor any conflict of interest, if any, which may arise between itself and such other parties. The trustee may have interest in, or may be providing, or may in the future provide financial services to other parties.

Currency Indemnity

        To the fullest extent permitted by law, our obligations to any holder of debt securities under the indenture or the applicable series of debt securities, as the case may be, shall, notwithstanding any judgment in a currency (the "Judgment Currency") other than U.S. dollars (the "Agreement Currency"), be discharged only to the extent that on the Business Day following receipt by such holder or the trustee, as the case may be, of any amount in the Judgment Currency, such holder or the trustee, as the case may be, may in accordance with normal banking procedures purchase the Agreement Currency with the Judgment Currency. If the amount of the Agreement Currency so purchased is less than the amount originally to be paid to such holder or the trustee, as the case may be, in the Agreement Currency, we agree, as a separate obligation and notwithstanding such judgment, to pay the difference and if the amount of the Agreement Currency so purchased exceeds the amount originally to be paid to such holder, such holder or the trustee, as the case may be, agrees to pay to or for our account such excess, provided that such holder shall not have any obligation to pay any such excess as long as a default by us in our obligations under the indenture or the debt securities of such series has occurred and is continuing, in which case such excess may be applied by such holder to such obligations.

ENFORCEABILITY OF CIVIL LIABILITIES

Cayman Islands

        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 Puglisi & Associates 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.

        Maples and Calder (Hong Kong) LLP, 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.

        Maples and Calder (Hong Kong) LLP 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. There is uncertainty with regard to Cayman Islands law relating to whether a judgment obtained from the United States courts under civil liability provisions of the securities laws of the United States will be determined by the courts of the Cayman Islands as penal or punitive in nature. 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

Table of Contents

punitive in nature. A Cayman Islands court may stay enforcement proceedings if concurrent proceedings are being brought elsewhere.

PRC

        King & Wood Mallesons, 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.

        King & Wood Mallesons 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 reciprocal arrangements 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.

        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.
