RISK FACTORS

         You should consider carefully all of the information in this prospectus, including the risks and uncertainties described below and our consolidated financial statements and related notes, before making an investment in our ADSs. Any of the following risks and uncertainties could have a material adverse effect on our business, financial condition, results of operations and prospects. The market price of our ADSs could decline significantly as a result of any of these risks and uncertainties, and you may lose all or part of your investment.

Risks Relating to Our Business and Industry

We are highly reliant on our proprietary technology infrastructure in our business operations, and failure to continue to improve and effectively utilize our technology infrastructure or successfully develop new technologies could harm our business operations, reputation and prospects.

        Technology is critical to our integrated solutions, connecting our systems with those of our ecosystem participants. While we have continuously enhanced our proprietary technology infrastructure, we may not be able to continue to improve our technology infrastructure and develop new technologies to meet the future needs of our business. If we are unable to maintain, improve and effectively utilize our technology infrastructure or to realize the expected results from our technology investments, our business, financial condition, results of operations and prospects, as well as our reputation, could be materially and adversely affected. Any problem with the functionality and effectiveness of our software or platforms could also result in unanticipated system disruptions, slower response times, impaired user experiences, delays in reporting accurate operating and financial information and inefficient management of our systems. In addition, enhancing our technology infrastructure requires significant investments of time and financial and managerial resources, including recruiting and training new technology personnel, adding new hardware and updating software and strengthening research and development. If our technology investments are unsuccessful, our business could suffer and we may be unable to recover the resources we commit to such initiatives.

We may not be able to maintain and enhance our ecosystem, which could negatively affect our business and prospects.

        Our ability to maintain a healthy and rich ecosystem that creates strong network effects among our ecosystem participants is critical to our success. While our ecosystem provides synergies and economies of scale across service lines and among our ecosystem participants, the extent to which we are able to maintain and strengthen the attractiveness of our ecosystem depends on our ability to offer a mutually beneficial platform for all participants, maintain the quality of our services and solutions, develop attractive services and solutions that meet the evolving needs of our ecosystem participants, reinforce the scope and scale of our ecosystem, and retain our participants. We must also provide sufficient geographic coverage to cement the effectiveness of our service network, continue to utilize data to improve service quality and operational efficiency of all ecosystem participants and maintain and improve our technology infrastructure as part of our single interoperable system to ensure seamless operations.

        In addition, our ecosystem participants may compete with one another, which may complicate the management of our ecosystem. Further, changes made to enhance our ecosystem or balance the interests of participants may be viewed positively by one participant but may have negative effects upon another. If we fail to balance the interests of all participants in our ecosystem, we may fail to further attract and retain additional ecosystem participants, which could adversely impact our business and financial condition.

If we are unable to continue to innovate, meet evolving market trends, adapt to changing customer demands and maintain our culture of innovation, our ability to sustain and grow our business may suffer.

        The ongoing success of our business depends on our ability to continue to introduce innovative solutions and services to meet evolving market trends and satisfy changing customer demands. We must continue to adapt by continuing innovation, improving our services and modifying our strategies, which could cause us to incur substantial costs. We may not be able to continue to innovate or adapt to changing market and customer needs in a timely and cost-effective manner, if at all. This could adversely impact our ability to embrace the changes brought by the New Retail era, expand our ecosystem and grow our business. Failure to develop new services to meet evolving market demands through innovation could cause us to lose current and potential customers and harm our operating results and financial condition.

        In addition, we may not be able to maintain our culture of innovation, which has been critical to our success and has helped us create value for our shareholders, succeed as a leader in our industry and attract, retain and motivate employees and other ecosystem participants. Among other challenges, we may not be able to identify and promote people in leadership positions who share our culture and can always focus on technology and innovation. Competitive pressure may also cause us to move in directions that may divert us from our mission, vision and values. If we cannot maintain our culture of innovation, our long-term business prospects could be materially and adversely affected.

We operate in a competitive industry, and if we fail to compete effectively, our business could suffer.

        We compete with total supply chain solution providers. As our operations encompass a broad range of areas, certain service lines may also face competition from other service providers in China, including supply chain management service providers, express delivery and freight service providers, B2B platforms for convenience stores, SaaS software service providers and logistics brokers. In addition to established players, we face competition from new market entrants. Increased competition may lead to a loss of market share, increasing difficulty in launching new service offerings, reduction in revenue or increase in loss, any one of which could harm our business, financial condition and results of operations.

        Our competitors may have a broader service or network coverage, more advanced technology infrastructure, stronger brand recognition and greater capital resources than we do. In addition, our competitors may reduce their rates to gain business, especially during times of reduced economic growth, and such reductions may limit our ability to maintain or increase our rates, maintain our operating margins or achieve growth in our business. The establishment by our competitors of cooperative relationships or competing networks to increase their ability to address the needs of our customers and other ecosystem participants could also negatively impact us. We may not be able to successfully compete against current or future competitors, and competitive pressures may have a material and adverse effect on our business, financial condition and results of operations.

Our business and growth are significantly affected by the emergence of New Retail, the continued development of e-commerce in China and elsewhere and related demand for integrated supply chain solutions.

        We serve merchants that conduct business in the retail industry in China, and these merchants rely on our services to fulfill orders placed by consumers. As we focus on providing integrated supply chain solutions for the New Retail era, our future business opportunities depend upon the continued integration of online and offline retail channels and the adoption of the New Retail paradigm by an increasing number of merchants in China and elsewhere, both in terms of large platforms and brands as well as small and medium enterprises, or SMEs, and micro-merchants.

        The future development and landscape of the retail industry in China and elsewhere are affected by a number of factors, many of which are beyond our control. These factors include the consumption

22

Table of Contents

power and disposable income of consumers, as well as changes in demographics and consumer preferences. The development of the retail industry is also subject to the selection, price and popularity of products offered through online and offline retail channels of original brand manufacturers and changes in the availability, reliability and security of such channels. Further, the emergence of alternative channels or business models that better suit the needs of consumers and the development of online-to-offline supply chain integration by retailers can also affect the development of the retail industry. Another important factor is the development of fulfillment, payment and other ancillary services associated with the retail industry. Macroeconomic conditions, particularly as retail spending tends to decline during recessions and other economic factors affecting consumer confidence, including inflation and deflation, fluctuation of currency exchange rates, volatility of stock and property markets, interest rates, tax rates and changes in unemployment rates, can also impact the development of the retail industry in China and elsewhere. Finally, other factors, such as changes in government policies, laws and regulations, in particular those that govern the retail industry, as well as changes in domestic and international politics, including military conflicts, political turmoil and social instability, can also influence the development of the retail industry in China and elsewhere. If New Retail, the e-commerce industry in China and their respective demand for integrated supply chain solutions fail to develop as we expect, our business and growth could be harmed.

We have a history of net losses and negative cash flows from operating activities, which may continue in the future.

        We incurred net losses of RMB718.5 million, RMB1,059.4 million, RMB1,363.5 million (US$201.1 million) and RMB624.6 million (US$92.1 million) in 2014, 2015, 2016 and the six months ended June 30, 2017, respectively. In addition, net cash used in operating activities was RMB328.9 million, RMB312.2 million and RMB788.8 million (US$116.4 million) in 2014, 2015 and 2016, respectively.

        We expect our costs and expenses to increase in absolute amounts due to (i) the continued expansion of our operations, which will cause us to incur increased costs and expenses associated with third-party transportation, labor, leasing property for the operation of our Cloud OFCs, hubs and sortation centers; (ii) the continued investment in our technology infrastructure and network; and (iii) the launch of new and additional value-added services, which may incur start-up costs, have different revenue and cost structures, and take time to achieve profitability.

        Our ability to achieve and maintain profitability depends on our ability to enhance our market position, maintain competitive pricing, leverage technology and business model innovation to expand and enhance our service offerings, and increase our operational efficiency. These are affected by many factors which may be beyond our control, such as the overall demand for supply chain services and general economic conditions, including levels of consumption. If we are unable to achieve profitability, we may have to cut down the scale of our operation, which may impact our business growth and adversely affect our financial condition and results of operations.

Our historical growth rates may not be indicative of our future growth, and if we are unable to manage our growth or execute our strategies effectively, our business and prospects may be materially and adversely affected.

        We have experienced significant growth in recent years. Our total revenue increased from RMB3,065.8 million in 2014 to RMB5,256.3 million in 2015 and further to RMB8,844.1 million (US$1,304.6 million) in 2016, and increased from RMB3,470.1 million in the six months ended June 30, 2016 to RMB8,104.1 million (US$1,195.4 million) in the same period in 2017. However, our past growth rates may not be indicative of future growth and our planned growth initiatives may not be successful. For example, the significant growth in our revenue from the six months ended June 30, 2016 to the same period in 2017 was due in part to the service scope expansion of BEST Express and

23

Table of Contents

BEST Freight starting in January 2017, among other factors. For additional information, see "Management's Discussion and Analysis of Financial Condition and Results of Operations—Results of Operations—Six Months Ended June 30, 2017 Compared to Six Months Ended June 30, 2016."

        Our rapid growth has placed, and will continue to place significant demands on our management and our technology infrastructure, as well as our administrative, operational and financial systems. We intend to achieve growth by continuing innovation, expanding market share, growing BEST Store ⁺ , broadening value-added services, expanding global reach, enhancing operational efficiency and quality, as well as growing through mergers, acquisitions and strategic alliances. There can be no assurance that we will be able to effectively manage our growth. If our growth initiatives fail, our businesses and prospects may be materially and adversely affected.

We are affected by seasonality experienced in the consumer retail and logistics and supply chain industries.

        Our businesses are affected by seasonality experienced in the consumer retail and logistics and supply chain industries. We typically experience a seasonal surge in sales, especially in our express operations, during the fourth quarter of each year as a result of stronger sales in connection with the Singles' Day and December 12 promotions, which may impose challenging resource and capacity demands on our business operations. Activity levels across our business lines are typically lower around Chinese national holidays, including Chinese New Year in the first quarter of each year, as consumer spending levels and shipment levels tend to be weaker.

        Seasonality also makes it challenging to forecast demand for our services, as the express, freight, supply chain management and store sales volumes can vary significantly and unexpectedly. We make planning and spending decisions, including capacity expansion, procurement commitments, personnel needs and other resource requirements based on our estimates of demand. Failure to meet demand associated with the seasonality in a timely manner may adversely affect our financial condition and results of operations.

Our success depends to a substantial degree upon our senior management, including Mr. Shao-Ning Johnny Chou and other key personnel, and our business operations would be negatively affected if we fail to attract and retain highly competent senior management.

        We depend to a significant degree on the continued service of Mr. Shao-Ning Johnny Chou, our founder, chairman and chief executive officer, our experienced senior management and other key personnel. If members of our senior management team or other key personnel resign, join a competitor or form a competing company, it could negatively impact our business operations and create uncertainty as we search for and integrate a replacement and could have an adverse effect on our financial condition and results of operations.

        We have entered into employment and confidentiality agreements with our senior management and other key personnel. However, these employment and confidentiality agreements do not ensure the continued service of these senior management and key personnel, and we may not be able to enforce these agreements. In addition, we do not maintain key man life insurance for any of the senior members of our management team or other key personnel.

We utilize franchisee partners to conduct certain aspects of our business, and face risks associated with these relationships, their employees and other personnel.

        We utilize franchisee partners to conduct certain aspects of our business. As of June 30, 2017, we had approximately 9,000 franchisee partners. Many of our franchisee partners sub-contract part of their businesses to sub-franchisees. Our control over franchisee partners and their sub-franchisees may not be as effective as if we had directly owned these partners' businesses, which could potentially make it

24

Table of Contents

difficult for us to manage them. Particularly, as we do not enter into agreements with sub-franchisees of our franchisee partners, we are unable to exert a significant degree of influence over them.

        Our franchisee partners, sub-franchisees and their employees directly interact with merchants and consumers in our ecosystem, and their performance directly affects our reputation and brand image. If our service personnel or those of our franchisee partners or sub-franchisees fail to satisfy the needs of our ecosystem participants, respond effectively to their complaints, which we have received from time to time, or provide services in a reliable, safe and secure manner, our reputation and the loyalty of our ecosystem participants could be negatively affected. As a result, we may lose ecosystem participants or experience a decrease in our business volume, which could have a material adverse effect on our business, financial condition and results of operations. We do not directly supervise the services provided by our franchisee partners and may not be able to successfully maintain and improve the quality of their services. Our franchisee partners may also fail to implement sufficient control over the pick-up and delivery personnel who work at the service stations in connection with their conduct, such as proper collection and handling of the items we transport and delivery service fees, adherence to privacy standards and timely delivery. As a result, we may suffer financial losses, incur liabilities and suffer reputational damages in the event of theft or late delivery of the items we ship, embezzlement of delivery service fees or mishandling of private information. In addition, while violation of laws and regulations by franchisee partners had not led to any material claim against us in the past, we cannot assure you that such claim will not arise in the future which may harm our brand or reputation or have other adverse impacts.

        Further, suspension or termination of a franchisee partner's services in a particular geographic area may cause interruption to or failure in our services in the corresponding geographic area. A franchisee partner may suspend or terminate its services voluntarily or involuntarily due to various reasons, including disagreement or dispute with us, failure to make a profit, failure to maintain requisite approvals, licenses or permits or to comply with other governmental regulations, and events beyond our or its control, such as inclement weather, natural disasters, transportation interruptions or labor unrest or shortage. Due to the intense competition in China's logistics and supply chain industry, our existing franchisee partners may also choose to discontinue their cooperation with us and work with our competitors instead. We may not be able to promptly replace our franchisee partners or find alternative ways to provide services in a timely, reliable and cost-effective manner, or at all. As a result of any service disruptions associated with our franchisee partners, satisfaction, brand, reputation, operations and financial performance of our ecosystem participants may be materially and adversely affected.

Our BEST Store ⁺ service line has a limited operating history.

        We have a very limited history in providing BEST Store ⁺ services, which were launched on a full-scale basis in March 2016. While we experienced rapid growth in this service line, we cannot assure you that we will be able to maintain its growth or successfully address any future problems or issues. We expect to continue to adjust our existing operating model and explore new operating model for this service line which may subject us to further uncertainties and negative effects on our overall business and results of operations.

        As we intend to grow the scale of BEST Store ⁺ , we may incur significant ramp-up costs to support such growth, which may negatively affect our profitability, particularly if we are unable to achieve economies of scale. For instance, we may not be able to increase margin or reduce costs as we expect. In addition, membership stores may not utilize Dianjia.com to procure merchandise to the extent we expect. We are also subject to risks related to our recent acquisition of WOWO. If we are unable to successfully integrate these additional stores into our platform, it could cause us to expend additional costs or deter others from partnering with us. See "—Any difficulties in identifying, consummating and integrating acquisitions, investments or alliances may expose us to potential risks and have an adverse effect on our business, results of operations or financial condition." We also face risks related to

25

Table of Contents

management of the merchandise inventories sold through Dianjia.com, and we depend on our demand forecasts for various kinds of products to make procurement decisions and to manage our inventories.

        We are also subject to risks that membership and self-operated stores fail to integrate with our service network as expected. We may also face challenges with the implementation of value-added services and last-mile delivery from convenience stores in our network. This may impact our ability to expand the number of membership stores in the network or retain or increase the activities of existing membership stores.

        We, as well as our membership BEST Store ⁺ operators, compete with numerous other convenience store chains, independent convenience stores, supermarkets, drugstores, motor fuel service stations, mass merchants, fast food operators and other similar retail outlets, who may have more experience than us, and may use promotional pricing or other discounts to encourage their in-store merchandise sales. Such competition may put pressure on us and our membership BEST Store ⁺ operators, and the results of operations of our BEST Store ⁺ service line may be materially and adversely affected.

We face challenges associated with diversifying our service offerings.

        We have in the past selectively launched new service lines such as BEST Store ⁺ , BEST Capital, BEST UCargo and other initiatives, and intend to continue to diversify our service offerings in the future. New services or new types of customers may involve risks and challenges we do not currently face. Such new initiatives may require us to devote significant financial and managerial resources and may not perform as expected.

        In addition, we may not be able to successfully anticipate and address customer demands and preferences in connection with new service offerings and our existing network and facilities may not be adaptable to the new services or customers. For example, different service offerings may impose different requirements and service standards. We may also be inexperienced with the operating models and cost structures associated with a new type of customer or service offering. If we take ineffective measures and cannot promptly adopt new and more effective measures, we may suffer losses. Further, we may not be able to ensure adequate service quality, and therefore may receive complaints or incur costly liability claims, which would harm our overall reputation and financial performance. We may not be able to achieve profitability or recoup our investments with respect to any new services or new types of customers in time or at all.

Macroeconomic and other factors that reduce demand for supply chain services, in China or globally, could have a material adverse impact on our business.

        The global logistics and supply chain industry has historically experienced cyclical fluctuations in financial performance due to economic recessions, reductions in per capital disposable income and levels of consumer spending, downturns in the business cycles of customers, interest rate fluctuations and economic factors beyond our control. During economic downturns, whether in China or globally, reduced overall demand for supply chain services will likely reduce demand for our services and solutions and exert downward pressures on our rates and margins. As we focus on providing integrated supply chain solutions in the New Retail era, if the online and offline retail channel integration trend or any other trend required for the emergence of New Retail does not develop as we expect, our business prospect may be adversely affected. In periods of strong economic growth, demand for limited transportation resources can also result in increased network congestion and operating inefficiencies. In addition, any deterioration in the economic environment subjects our business to various risks that may have a material impact on our operating results and future prospects. For instance, some of our customers may face economic difficulties and may not be able to pay us, and some may go out of business. These customers may not complete their payments as quickly as they have in the past, causing our working capital needs to increase.

26

Table of Contents

        In an economic downturn, we may not be able to appropriately adjust our expenses to changing market demands and it may be more difficult to match our staffing levels to our business needs. In addition, we have certain significant fixed expenses and other variable expenses that are fixed for a period of time, which we may not be able to adequately adjust in a period of rapid change in market demand.

We have not recognized any share-based compensation expense in the past but will recognize a substantial amount of share-based compensation expense upon the completion of this offering, which will have a significant impact on our results of operations.

        We adopted our 2008 equity and performance incentive plan in June 2008 pursuant to which we may grant options to purchase up to 20,934,684 of our ordinary shares, and our 2017 equity incentive plan in September 2017 pursuant to which we may grant equity-based awards representing initially 10,000,000 Class A ordinary shares, which number will automatically be increased by a maximum of 2% of our total outstanding shares at the end of preceding calendar year on January 1, 2019 and on every January 1 thereafter for eight years (subject to certain limitations). As of the date of this prospectus, we have outstanding options with respect to 19,072,006 ordinary shares that have been granted to our employees, directors and consultants under the 2008 equity and performance incentive plan. We are required to account for share options granted to our employees, directors and consultants in accordance with Codification of Accounting Standards, or ASC 718, " Compensation—Stock Compensation " and ASC 505-50, " Equity, Equity-Based Payments to Non-Employees ." We are required to classify share options granted to our employees, directors and consultants as equity awards and recognize share-based compensation expense based on the fair value of such share options, with the share-based compensation expense recognized over the period in which the recipient is required to provide service in exchange for the equity award. Because the exercisability of the share options granted by us is conditional upon completion of this offering or, in case we have waived such restriction, our obligation to issue ordinary shares pursuant to any exercise of the options is conditional upon the completion of this offering, we have not recognized share-based compensation expense relating to these share options granted by us yet.

        As a result, upon the completion of this offering, we expect to begin to recognize a substantial amount of share-based compensation expense, and we expect the recognition of such share-based compensation expenses to have a significant impact on our results of operations in the fiscal quarter in which this offering is completed. As of June 30, 2017, the total unrecognized compensation costs associated with share options granted to employees amounted to US$40.0 million. With respect to options granted to non-employees, as their inability to exercise these options or receive any ordinary shares until completion of this offering constitutes a performance condition that is not considered probable until the completion of this offering, we cannot establish the fair value of these options to determine the unrecognized share-based compensation expense associated with them prior to the completion of this offering. Moreover, if additional share options or other equity incentives are granted to our employees, directors or consultants in the future, we will incur additional share-based compensation expense and our results of operations will be further adversely affected. For further information on our share incentive plans and information on our recognition of related expenses, please see "Management's Discussion and Analysis of Financial Condition and Results of Operations—Components of Results of Operations—Share-Based Compensation" and "Management—Share Incentive Plans."

We currently derive a significant portion of our revenue from consumer activity on a limited number of prominent e-commerce platforms, and a reduction of demand from these platforms may negatively affect our business.

        A significant portion of our revenue is derived from a number of major e-commerce platforms in China, such as Taobao Marketplace and Tmall. If these platforms are to suffer a decline in their usage

27

Table of Contents

or if our relationships with them are to be harmed, it could materially and negatively impact our business and operating results and financial condition. We generally do not have long-term contractual relationships with e-commerce platforms, and instead individual merchants on such platforms select us as their shipping and other supply chain service provider. If we are unable to remain a preferred service provider for the merchants on these e-commerce platforms, our business volume may decrease significantly, which could adversely affect our business and results of operations.

If our customers are able to reduce their logistics and supply chain costs or increase utilization of their internal solutions, our business and operating results may be materially and adversely affected.

        A major driver for merchants and other customers to use third-party logistics and supply chain service providers is the high cost and degree of difficulty associated with developing in-house logistics and supply chain expertise and operational efficiencies. If, however, our customers are able to develop their own logistics and supply chain solutions, increase utilization of their in-house supply chain, reduce their logistics spending, or otherwise choose to terminate our services, our logistics and supply chain management business and operating results may be materially and adversely affected. In addition, certain of our major e-commerce platform partners may develop their own logistics capabilities, which could reduce the scope of services we provide to users on their platforms.

Decreased availability or increased costs of key logistics and supply chain inputs, including third-party transportation, equipment and materials could impact our cost of operations and our profitability across business lines.

        We depend on reliable access to third-party transportation, supplies of equipment, including vehicles and the sorting machines, conveyor systems and Automated Guided Vehicles, or AGVs, used at our Cloud OFCs and other network facilities, replacement parts and materials such as packing. The supplier base providing logistics equipment is relatively consolidated, which has resulted in a limited number of suppliers for certain types of equipment and supplies. Conversely, the market for third-party transportation services is fragmented with a large number of service providers, and it can be difficult to find reliable partners whose performance and reliability meet our standards at the scale our operations require. Any significant reduction in availability or increase in cost of any logistics and supply chain inputs could adversely affect our operations and increase our costs, which could adversely affect our operating results and cash flows.

Overall tightening of the labor market, increases in labor costs or any labor unrest, including strikes, may affect our business as we operate in a labor-intensive industry.

        Our business requires a substantial number of personnel, and labor costs comprised 25.2%, 27.3%, 24.4% and 15.4% of our total cost of revenue in 2014, 2015, 2016 and the six months ended June 30, 2017, respectively. Any failure to retain stable and dedicated labor by us, our franchisee partners or service providers may lead to disruptions to or delays in our services. We, our franchisee partners and service providers often hire additional or temporary workers to handle the significant increase in express and freight volumes during peak periods of e-commerce activities. We have observed an overall tightening labor market. We have experienced, and expect to continue to experience, increases in labor costs due to increases in salaries, social benefits and employee headcounts and we may also face seasonal labor shortages. We, our franchisee partners and service providers compete with other companies for labor, and we may not be able to offer competitive salaries and benefits compared to them.

        We, our franchisee partners and service providers have been subject to labor disputes from time to time in the ordinary course of business, although none of them, individually or in the aggregate, has had a material adverse impact on us. We expect to continue to be subject to various legal or administrative proceedings related to labor disputes in the ordinary course of our business, due to the

28

Table of Contents

magnitude of the labor force involved in our service network. Any labor unrest or strikes directed against us, our franchisee partners or service providers could directly or indirectly prevent or hinder our normal operating activities, and if not resolved in a timely manner, lead to delays in fulfilling our customer orders. We, our franchisee partners and service providers are not able to predict or control any labor unrest, especially those involving labor not directly employed by us. Further, labor unrest may affect general labor market conditions or result in changes to labor laws, which in turn could materially and adversely affect our business, financial condition and results of operations.

We engage outsourcing firms to provide outsourced personnel for our operations and have limited control over these personnel and may be liable for violations of applicable PRC labor laws and regulations.

        We engage outsourcing firms who send large numbers of their employees to work at our network facilities. As of June 30, 2017, over 28,000 outsourced personnel were active in our operations. We enter into agreements with the outsourcing firms only and do not have any contractual relationship with these outsourced workers. Since these outsourced personnel are not directly employed by us, our control over them is more limited as compared to our own employees. If any outsourced personnel fail to operate in accordance with our instructions, policies and business guidelines, our market reputation, brand image and results of operations could be materially and adversely affected.

        Our agreements with the outsourcing firms provide that we are not liable to the outsourced personnel if the outsourcing firms fail to fulfill their duties to these personnel. However, if the outsourcing firms violate any relevant requirements under the applicable PRC labor laws, regulations or their employment agreements with the personnel, such personnel may claim compensation from us as they provide their services at our network facilities. As a result, we may incur legal liability, and our market reputation, brand image as well as our business, financial condition and results of operations could be materially and adversely affected.

Our business depends on our reputation and brand image, and any damage to them or any failure to effectively adjust our branding strategy in our international expansion could adversely impact our business.

        Our brand name in Chinese, " ," means hundreds of generations. We believe that our BEST brand name and our other brands stand for long-term commitment, comprehensive and high-quality service, reliability and efficiency, and are part of our most important and valuable assets. We have registered our major trademarks critical to our business in Chinese with the relevant PRC authorities, including " " (BEST), " " (BEST Logistics), " " (BEST Supply Chain), " " (BEST Express), " " (BEST Freight), " " (BEST Global), " " (BEST Capital), " " (BEST UCargo) and " +" (Store ⁺ ). We have also used and registered our various trademarks in other jurisdictions. Our brands and reputation are significant sales and marketing tools, and we devote substantial resources to promoting and protecting them. Adverse publicity (whether or not justified) such as accidents, customer service mishaps or noncompliance with laws relating to activities by our franchisee partners, service providers, contractors or agents, could tarnish our reputation and reduce the value of our brand. With the increased use of social media outlets, adverse publicity can be disseminated quickly and broadly, making it increasingly difficult for us to effectively respond.

        As we continue our international expansion, we may need to adjust our branding strategy in new countries and regions that we enter into. For example, our existing brands may be viewed as similar to brands used by existing players in the local markets that provide similar services. As such, we may need to adopt a new brand name in these markets and our efforts in establishing the reputation of the new brand in a new market may not be successful and could lead to brand disruption and harm our operations in these markets. Existing players in the local markets may also claim that our brands are similar to theirs and thereby bring claims against us for infringement upon their brand names or trademark rights, which may cause harm to our reputation and disrupt our branding strategy in the relevant local market. Damage to our reputation and loss of brand equity could reduce demand for our services and thus have an adverse effect on our financial condition, liquidity and results of operations, as well as require additional resources to rebuild our reputation and restore the value of our brand.

We may not be able to attract and retain the qualified and skilled employees needed to support our business.

        We believe our success depends on the efforts, effectiveness and talent of our employees, including research and development, supply chain management, operations, engineering, risk management, and sales and marketing personnel. Our future success depends on our continued ability to attract, develop, motivate and retain qualified and skilled employees. Competition for highly skilled personnel is extremely intense. We may not be able to hire and retain these personnel at compensation levels consistent with our existing compensation and salary structure. Some of the companies with which we compete for experienced employees have greater resources than we have and may be able to offer more attractive terms of employment.

        In addition, we invest significant time and resources in training our employees, which increases their value to competitors who may seek to recruit them. If we fail to retain our employees, we could incur significant expenses in hiring and training their replacements, and the quality of our services and our ability to serve our customers could diminish, resulting in a material adverse effect to our business.

A significant system disruption could adversely affect the operations of us and our ecosystem participants, which could severely impact our business and prospects.

        We rely on our technology infrastructure to process, transmit and store digital information, and to manage or support a variety of business processes and activities. In addition, the provision of service to our customers and the operation of our service network infrastructure involves the storage and transmission of proprietary information and sensitive or confidential data, including business and personal information of our ecosystem participants, who are reliant on the use of our technology infrastructure to manage their business processes and activities. Our technology infrastructures and those of our customers and our franchisee partners are connected through various interfaces. Some of these infrastructures are managed by third-parties and are susceptible to damage, disruptions or shutdowns due to failures during the process of upgrading or replacing software, databases or components thereof, power outages, hardware failures, computer viruses, malicious insiders, telecommunication failures, user errors or other catastrophic events. Hackers, acting individually or in coordinated groups, may also launch distributed denial of service attacks or other coordinated attacks that may cause service outages or other interruptions in our business.

        The techniques used to obtain unauthorized access, disable or degrade service or sabotage systems change frequently, may be difficult to detect and often are not recognized until launched against a target. As a result, we may be unable to anticipate these techniques or to implement adequate preventative measures. If our systems were to suffer an operational failure, it could harm our reputation and have material adverse effect on our business and prospects.

Our business generates and processes a large quantity of data, and improper handling of or unauthorized access to such data may adversely affect our business.

        We face risks related to complying with applicable laws, rules and regulations relating to the collection, use, disclosure and security of personal information, as well as any requests from regulatory and government authorities relating to such data.

        The PRC regulatory and enforcement regime with regard to data security and data protection has continued to evolve. There are uncertainties on how certain laws and regulations will be implemented in practice. PRC regulators have been increasingly focused on regulating data security and data protection. We expect that these areas will receive greater attention from regulators, as well as attract public scrutiny and attention going forward. This greater attention, scrutiny and enforcement, including more frequent inspections, 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, our reputation and results of operations could be materially and adversely affected. For further details please see "Regulation—Regulations Relating to Internet Security."

        We also grant limited access to specified data on our technology platform to certain other ecosystem participants. These third parties face the same challenges and risks inherent in handling and protecting large volumes of data. Any system failure or security breach or lapse on our part or on the part of any of such third parties that results in the release of user data could harm our reputation and brand and, consequently, our business, in addition to exposing us to potential legal liability.

        In addition, we are subject to additional laws in other jurisdictions in which we operate and where our ecosystem participants are located. The laws, rules and regulations of other jurisdictions, such as the U.S. and Europe, may impose more stringent or conflicting requirements and penalties than those in China, compliance with which could require significant resources and costs. Our policies and practices concerning the collection, use and disclosure of user data are posted on our websites. Any failure, or perceived failure, by us to comply with any regulatory requirements or privacy protection-related laws, rules and regulations could result in proceedings or actions against us by governmental entities or others. These proceedings or actions could subject us to significant penalties and negative publicity, require us to change our business practices, increase our costs and severely disrupt our business.

We face risks associated with the items we deliver and the contents of shipments and inventories handled through our service network.

        We handle a large volume of shipments and inventories across our service network, and face challenges with respect to the protection and control of these items. Shipments and inventories in our service network may be stolen, damaged or lost for various reasons, and we, our franchisee partners and service providers may be perceived or found to be liable for such incidents. In addition, we may fail to screen shipments and inventories and detect unsafe or prohibited/restricted items. Unsafe items, such as flammables and explosives, toxic or corrosive items and radioactive materials, may damage other items or facilities in our service network, injure recipients and harm our personnel and assets or those of our franchisee partners and service providers. Furthermore, if we fail to prevent prohibited or restricted items from entering into our service network and if we participate in the transport and delivery of such items, we may be subject to administrative or even criminal penalties, and if any personal injury or property damage is concurrently caused, we may be further liable for civil compensation.

        Our delivery operations also involve inherent risks. We constantly have a large number of vehicles and personnel in transportation and a large number of items in storage facilities that we rent, and are therefore subject to risks associated with storage and transportation safety. The insurance maintained by us may not fully cover the damages caused by transportation related injuries or loss. From time to time, our vehicles and personnel may be involved in accidents, and the items they transport may be lost or damaged. In addition, frictions or disputes may occasionally arise from the personal interactions between our pick-up and delivery personnel and senders or recipients and those of our franchisees partners and service providers. Personal injury or property damage may occur in connection with such incidents.

        Any of the foregoing could disrupt our services, cause us to incur substantial expenses and divert the time and attention of our management. We, our franchisee partners and service providers may face claims and incur significant liabilities if found liable or partially liable for any injuries, damages or losses. Claims against us may exceed the amount of our insurance coverage, or may not be covered by insurance at all. Governmental authorities may also impose significant fines on us or require us to adopt costly preventive measures. Furthermore, if our services are perceived to be insecure or unsafe by our ecosystem participants, our business volume may be significantly reduced, and our business, financial condition and results of operations may be materially and adversely affected.

We have limited ability to protect our intellectual property rights, including our brand and our proprietary information technology platform, and unauthorized parties may infringe upon or misappropriate our intellectual property.

        Our success depends in part upon our proprietary technology infrastructure, including certain methodologies, practices, tools and technical expertise we utilize in designing, developing, implementing and maintaining applications and processes used in providing our services. We rely on a combination of patent, copyright, trademark, trade secrets and other intellectual property protections, confidentiality agreements with our key personnel, customers and other relevant persons and other measures to protect our intellectual property, including our brand and our proprietary technology infrastructure. Nevertheless, it may be possible for third parties to obtain and use our intellectual property without authorization. The unauthorized use of intellectual property is common in China and enforcement of intellectual property rights by PRC regulatory agencies is inconsistent. As a result, litigation may be necessary to enforce our intellectual property rights. Litigation could result in substantial costs and diversion of our management's attention and resources, and could disrupt our business, as well as have a material adverse effect on our financial condition and results of operations. Given the relative unpredictability of the PRC's legal system and potential difficulties in enforcing a court judgment, there is no guarantee that we would be able to halt any unauthorized use of our intellectual property in China through litigation.

We may be accused of infringing the intellectual property rights of others.

        Our success depends in part on the use of our proprietary intellectual property and the intellectual property of other ecosystem participants, including technology, software products, business policies, plans, and trade secrets. Many of our contracts with third parties require us not to engage in the unauthorized use of such intellectual property or information, and to indemnify such third parties for any resulting loss. The steps taken by us in this regard may not be adequate to safeguard such intellectual property and confidential information. Moreover, most of our contracts do not include any limitation on our liability with respect to our infringement or breach of our obligation to keep confidential the intellectual property or confidential information. In addition, we may not always be aware of intellectual property registrations or applications relating to trademarks, source codes, software products or other intellectual property of such third parties, whether in China or other jurisdictions. As a result, if the proprietary rights of our ecosystem participants or other third parties are misappropriated by us or our employees, we may be liable for damages or other compensation.

        Assertions of infringement of intellectual property or misappropriation of confidential information against us, if successful, could have a material adverse effect on our business, financial condition and results of operations. Protracted litigation could divert our management's attention and our resources and also result in existing or potential customers deferring or limiting their procurement or use of our services until resolution of such litigation. Even if such assertions against us are unsuccessful, they may cause us to lose existing and future business and incur reputational harm and substantial legal fees.

Any difficulties in identifying, consummating and integrating acquisitions, investments or alliances may expose us to potential risks and have an adverse effect on our business, results of operations or financial condition.

        We have in the past made and may in the future seek to make acquisitions and investments and enter into strategic alliances to further expand our business. If we are presented with appropriate opportunities, we may acquire additional businesses, services, resources, or assets, including supply chain service providers and transport solution providers that are accretive to our core business. We cannot assure you that we will always be able to complete such acquisitions successfully or on terms acceptable to us. Integration of entities or assets we acquire into our business may not be successful and may prevent us from expanding into new services, customer segments or operating locations. This could significantly affect the expected benefits of these acquisitions. Moreover, the integration of any

32

Table of Contents

acquired entities or assets into our operations could require significant attention from our management. The diversion of our management's attention and any difficulties encountered in any integration process could have an adverse effect on our ability to manage our business.

        Our possible future acquisitions, investments or strategic alliances may also expose us to other potential risks, including risks associated with unforeseen or hidden liabilities, the diversion of resources from our existing businesses and technologies, our inability to generate sufficient revenue to offset the costs, expenses of acquisitions and potential loss of, or harm to, relationships with employees and customers as a result of our integration of new businesses. In addition, we may recognize impairment losses on goodwill arising from our acquisitions. The occurrence of any of these events could have a material and adverse effect on our ability to manage our business, our financial condition and our results of operations.

Our international expansion exposes us to significant risks.

        We provide inbound and outbound cross-border supply chain management services and plan to continue to expand our footprint internationally as part of our growth strategy. In addition to China, we currently operate warehouses in the U.S. and Germany, provide coverage through partners in Canada, Japan and Australia and expect to open additional foreign facilities and hire employees to work at these offices in order to reach new customers and expand the reach of our service network. Operating in international markets requires significant resources and management attention and will subject us to regulatory, economic and political risks in addition to those we already face in China. Because of our limited experience with international operations as well as developing and managing operations in international markets, our international expansion efforts may not produce the results we expect.

        In addition, we will face risks in doing business internationally that could adversely affect our business. For instance, we face difficulties managing and staffing international operations and the increased operating, travel, infrastructure and legal compliance costs associated with international business. We must comply with laws and regulations in foreign jurisdictions, particularly in the areas of data privacy and customs. We must also comply with technical and environmental standards in these jurisdictions. In addition, we must offer customer service in various languages, adapt and localize our service offerings for specific countries, appropriately price our products and services and work with overseas merchants, partners and other third parties, such as local transportation service providers. We are also subject to general risks inherent in international operations, such as fluctuations in exchange rates, changes in trade policies, tariff regulations, embargoes and customer clearances, or other trade restrictions, as well political or social unrest or economic instability in regions in which we operate.

        Our failure to manage any of these risks successfully could harm our international operations, and adversely affect our business, results of operations and financial condition.

We may not be able to obtain sufficient capital to fund our business expansion.

        Our business expansion requires substantial amount of capital. In 2014, 2015, 2016 and the six months ended June 30, 2017, we incurred capital expenditures of RMB212.5 million, RMB398.1 million, RMB628.5 million (US$92.7 million) and RMB320.4 million (US$47.3 million), respectively, representing purchases of property and equipment. We have incurred and expect to continue to incur substantial costs to launch and ramp-up new service offerings and we may only be able to recover such costs over the long term. The continued improvement and upgrade of our supply chain service network may also require substantial amount of capital investments, such as purchasing equipment, funding leasehold improvements at our hubs, sortation centers and Cloud OFCs and expanding our BEST Store ⁺ network. Further, we may encounter development delays and excess development costs.

Table of Contents

        We have historically funded our operations by issuance of equity securities, preferred shares and short-term bank borrowings. There can be no assurance that we will be able to generate sufficient cash from our operations to fund our capital requirements or raise additional funds through equity or debt financings on satisfactory terms or at all, in which case we may be required to prioritize projects or curtail capital expenditures, and our results of operations could be adversely affected. On the other hand, if we raise funds through debt financings, we may also become subject to restrictive covenants that could limit our future capital raising activities and other financial and operational matters. If we raise funds through further issuances of equity or equity-linked securities, our existing shareholders could suffer significant dilution in their percentage ownership of our company.

Failure of us or our franchisee partners to obtain, maintain or update necessary licenses and permits may have material adverse effect on our business, financial condition and results of operations.

        We and our franchisee partners are required to hold a number of licenses and permits in connection with our business operation including, but not limited to, the courier service operation permit, road transportation operation permit and the value-added telecommunication service license concerning Internet information service, or the ICP license.

        Under PRC laws, an enterprise that operates and provides express delivery services must obtain a courier service operation permit listing out all the regions it and its branches are allowed to operate in. Such enterprise needs to make a filing with the relevant postal authority to update its courier service operation permit to include any additional regions it plans to expand into. All of our PRC subsidiaries, our VIE and its subsidiaries engaging in express delivery services have obtained courier service operation permits required for our operations. However, some local branches of our VIE and its subsidiaries have not made timely filings with the relevant postal authority to update their courier service operation permits. While we have not received any government order or penalty resulting from such failure, we cannot assure you that we will not be subject to orders to rectify, fines of up to RMB50,000 or business suspension of such branches.

        In addition, an enterprise engaging in road freight transportation is required to obtain a road transportation operation permit from the relevant county-level road transportation administrative bureau, while a foreign-invested enterprise (including its subsidiaries) engaging in road freight transportation must obtain the approval from the provincial-level road transportation administrative bureau. If an enterprise engaging in road freight transportation intends to establish a branch, it is required to make a filing with the local road transportation administrative bureau where the branch is to be established. While all of our PRC subsidiaries, the VIE and its subsidiaries engaging in road freight transportation have obtained their road transportation operation permits, we are in the process of renewing the filings for some of the branches, and if we cannot complete the renewal in a timely manner, these branches may be subject to business suspension and other penalties.

        Our franchisee partners also need to obtain necessary licenses and permits and make necessary filings to provide express delivery services. Some of our franchisee partners providing express delivery services do not currently possess all necessary licenses and permits. While we have urged them to obtain such licenses and permits, we can provide no assurance that all of our franchisee partners will be able to obtain all of the licenses and permits and make all of the filings necessary for their business. Failure to obtain such licenses and permits and make such filings may result in suspension of operation, fines or other penalties on our franchisee partners by government authorities. In addition, if any of our franchisee partners providing express delivery services fails to obtain required licenses and permits, we may also be subject to an order to rectify and a fine ranging from RMB5,000 to RMB30,000 for each such failure.

        New laws and regulations that are enforced from time to time may require additional licenses and permits other than those we and our franchisee partners currently have. If the PRC government

34

Table of Contents

considers us or our franchisee partners to be operating without the proper approvals, licenses or permits or promulgates new laws and regulations that require additional approvals or licenses, it has the authority, 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 and adverse effect on our results of operations.

Failure to comply with PRC laws and regulations by us or our franchisee partners may materially and adversely impact our business, financial condition and results of operations.

        Our business is subject to governmental supervision and regulation by the relevant PRC governmental authorities, including but not limited to the State Post Bureau and the Ministry of Transportation. Together, these governmental authorities promulgate and enforce regulations that cover many aspects of our day-to-day operations, and we may fail to fully comply with these regulations. For example, the PRC Postal Law, promulgated by the Standing Committee of the National People's Congress of China, which became effective on October 1, 2009 and was amended in 2015, indicates that express delivery companies cannot engage in "posting and mail delivery business exclusively operated by postal enterprises." However, PRC laws do not provide a definition for "posting and mail delivery business exclusively operated by postal enterprises." If the authorities define such term in the future and if the items that we or our franchisee partners deliver fall into the defined category, we may be considered in violation of such regulation, and as a result, it might have an adverse impact on our results of operations.

        According to the Administrative Measures for Express Delivery Market, or the Express Delivery Regulations, promulgated by the Ministry of Transport on January 11, 2013, when engaging in express delivery business through franchising arrangements, a franchisor is required to execute written agreements with its franchisees to set forth their respective rights and obligations with respect to their franchising arrangement and clearly delineate their respective liabilities to consumers in case of any infringement of their lawful rights. Failure to enter into such a written agreement with any franchisee may subject a franchisor to an order to rectify and a fine ranging from RMB5,000 to RMB30,000. While it is not clearly provided in the Express Delivery Regulations, national government authorities have imposed that certain specific forms be used in connection with the execution of the written agreements required under the Express Delivery Regulations. While the majority of our agreements with franchisee partners for express delivery service have satisfied such form requirements, our other agreements with such franchisee partners may be found non-compliant by relevant authorities. Although we have proactively taken measures to ensure that our agreements with franchisee partners will comply with such requirements, we cannot assure you that we will not be subject to fines and penalties due to any past or future non-compliances.

        Pursuant to the Administrative Regulations on Commercial Franchising Operation promulgated by the State Council in February 2007 and Provisions on Administration of the Record Filing of Commercial Franchises issued by MOFCOM in December 2011, or collectively the Regulations and Provisions on Commercial Franchising, commercial franchising refers to the business activities where an enterprise that possesses the registered trademarks, enterprise logos, patents, proprietary technology or any other business resources allows such business resources to be used by another business operator through a contract and the business operator follows the uniform business model to conduct business operations and pay franchising fees according to the contract. Therefore, if the relationship between us and our franchisee partners and other ecosystem participants constitute such regulated commercial franchising, we will be subject to these regulations and will be required to file such franchising arrangements with MOFCOM or its local counterparts and update the filings when there are changes to relevant information. While we have completed such filings with respect to our BEST Express, BEST Freight and Cloud OFC services as of the date of this prospectus, we cannot assure you that we

35

Table of Contents

can update such filings in a timely manner or our relationships with other existing and future ecosystem participants will not be found to constitute such regulated commercial franchising in the future. As of the date of this prospectus, we have not received any request from any governmental authorities to make any of such filings. If relevant authorities determine that we failed to make any filing with respect to any regulated commercial franchising activity in the future, we may be subject to an order to rectify or fines ranging from RMB10,000 to RMB50,000, and if we fail to rectify within the rectification period determined by competent government authorities, we may be subject to an additional fine ranging from RMB50,000 and RMB100,000 as well as public reprimand.

        In addition, our franchisee partners have full discretion over their daily operations and make localized decisions with respect to their facilities, vehicles and hiring and pricing strategies. Their operations are regulated by various PRC laws and regulations, including local administrative rulings, orders and policies that are pertinent to their localized freight, express delivery business and retail business. For example, local regulations may specify the models or types of vehicles to be used in pickup and delivery services or require the franchisee partners to implement heightened safety screening procedures, which could materially drive up the operating costs and impact the delivery efficiency of the pickup and delivery outlets.

        We are also subject to a number of retail industry regulations including, but not limited to, regulations relating to pricing, consumer protection, product quality, food safety and public safety. Local regulatory authorities conduct periodic inspections, examinations and inquiries in respect of our compliance with relevant regulatory requirements. If we, or our membership stores, fail to comply with these laws and regulations, we or our membership stores may be exposed to penalties, fines, the suspension or revocation of our or our membership stores' licenses or permits to conduct business, administrative proceedings and litigation.

        New laws and regulations may be enforced from time to time and substantial uncertainties exist regarding the interpretation and implementation of current and any future PRC laws and regulations applicable to our businesses. If the PRC government promulgates new laws and regulations that impose additional restrictions on our daily operations, it has the authority, among other things, to levy fines, confiscate income, revoke 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 and adverse effect on our results of operations. If our franchisee partners are found to be in violation of any applicable law or regulation then in effect, such franchisee partners may be subject to similar penalties or administrative orders and may not be able to continue to deliver satisfactory services or at all. As a result, our business, reputation, financial condition and results of operations may be materially and adversely affected.

We face risks related to the termination and renewal of leases on which we rely for our operations.

        Substantially all of our Cloud OFCs, hubs and sortation centers are located in properties for which we have entered into long-term operating leases. In some instances, we may negotiate an option to renew the lease according to the terms and conditions under the relevant lease agreements. However, upon the expiration of such leases, we may not be able to renew these leases on commercially reasonable terms, if at all. Under certain lease agreements, the lessor may terminate the agreement by giving prior notice and paying default penalties to us. Such default penalties nonetheless may not be sufficient to cover our losses. Even though the lessors for most of our Cloud OFCs, hubs and sortation centers do not have the right of unilateral early termination unless they provide the required notice, the lease may nonetheless be terminated early if we are in material breach of the lease agreements. We may assert claims for compensation against the landlords if they elect to terminate a lease agreement early and without due cause. If the leases for our Cloud OFCs, hubs or sortation centers were terminated prior to their expiration dates, notwithstanding any compensation we may receive for early

36

Table of Contents

termination of such leases, or if we are not able to renew such leases, we may have to incur significant cost related to relocation.

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

        As of the date of this prospectus, lessors of approximately 20% of the total gross floor area of our leased properties in China have not provided us with their property ownership certificates or any other documentation proving their right to lease those properties to us. If our lessors are not the owners of the properties and they have not obtained consents from the owners or their lessors or permits from the relevant governmental authorities, our leases could be invalidated. If this occurs, we may have to renegotiate the leases with the owners or other parties who have the right to lease the properties, and the terms of the new leases may be less favorable to us. Although we may seek damages from such lessors, such leases may be void and we may be forced to relocate. Any relocation would require us to locate and secure additional facilities, expenditures of additional funds in connection with the relocation and preparation of replacement facilities. This could affect our ability to provide uninterrupted services to our customers and harm our reputation. As of the date of this prospectus, we have not incurred expenditures associated with the relocation and preparation of replacement facilities. In addition, a substantial portion of our leasehold interests in leased properties have not been registered with the relevant PRC governmental authorities as required by relevant PRC laws. The failure to register leasehold interests may expose us to potential warnings and penalties.

        In addition, some of our leased properties in China may not have filed the fire-control registration as required by relevant PRC laws and as a result, our use of the leased property may be affected. In the event that our use of properties is successfully challenged by the regulators or due to fire incidents, we may be forced to relocate from the affected operations.

Our failure or alleged failure to comply with China's anti-corruption laws or the U.S. Foreign Corrupt Practices Act could result in penalties, which could harm our reputation and have an adverse effect on our business, results of operations and financial condition.

        We are subject to PRC laws and regulations related to anti-corruption, which prohibit bribery to government agencies, state or government owned or controlled enterprises or entities, to government officials or officials that work for state or government owned enterprises or entities, as well as bribery to non-government entities or individuals. Upon the completion of this offering, we will also be subject to the U.S. Foreign Corrupt Practices Act, or the FCPA, which generally prohibits companies and any individuals or entities acting on their behalf from offering or making improper payments or providing benefits to foreign officials for the purpose of obtaining or keeping business, along with various other anti-corruption laws. Our existing policies prohibit any such conduct and we are in the process of implementing additional policies and procedures, and providing training, to ensure that we, our employees, franchisee partners and other third parties comply with PRC anti-corruption laws and regulations, the FCPA and other anti-corruption laws to which we are subject. There is, however, no assurance that such policies or procedures will work effectively all the time or protect us against liability under the FCPA or other anti-corruption laws. There is no assurance that our employees, franchisee partners and other third parties would always obey our policies and procedures. Further, there is uncertainty in connection with the implementation of PRC anti-corruption laws. We could be held liable for actions taken by our employees, franchisee partners and other third parties with respect to our business or any businesses that we may acquire. In addition to the PRC, we also operate warehouses in the U.S. and Germany and provide coverage in Canada, Japan and Australia through our partners. This puts us in frequent contact with persons who may be considered "foreign officials" under the FCPA, resulting in an elevated risk of potential FCPA violations. If we are found not to be in compliance with PRC anti-corruption laws, the FCPA and other applicable anti-corruption laws, we

37

Table of Contents

may be subject to criminal, administrative, and civil penalties and other remedial measures, which could have an adverse impact on our business, results of operations and financial condition. Any investigation of any potential violations of the FCPA or other anti-corruption laws by U.S. or foreign authorities, including Chinese authorities, could adversely impact our reputation, cause us to lose customer relationships and lead to other adverse impacts on our business, results of operations and financial condition.

We are subject to various claims and lawsuits in the ordinary course of business, and increases in the amount or severity of these claims and lawsuits could adversely affect us.

        We are exposed to various claims and litigation related to commercial disputes, personal injury, property damage, labor disputes and other matters in the ordinary course of our business. Developments in regulatory, legislative or judicial standards, material changes to litigation trends, or a catastrophic accident or series of accidents, including accidents that affect our franchisee partners or service providers, involving any or all of commercial disputes, property damage, personal injury, and labor disputes could have a material adverse effect on our operating results, financial condition and reputation.

We may not have sufficient insurance coverage.

        We maintain various insurance policies to safeguard against risks and unexpected events. We have purchased certain life insurance, such as group accident insurance; property loss insurance, such as cargo transportation insurance and all-risk property insurance; and liability insurance, such as non-motor vehicle liability insurance, public liability insurance and logistics liability insurance. Some of our insurance also covers fire or other damages. We also provide social security insurance including pension insurance, unemployment insurance, work-related injury insurance and medical insurance for our full-time employees. We are not legally required to maintain insurance for the items we ship. We do not maintain business interruption insurance or general third-party liability insurance, nor do we maintain key-man life insurance. We cannot assure you that our insurance coverage is sufficient to prevent us from any losses or that we will be able to successfully claim for losses under our current insurance policies on a timely basis, or at all. If we incur losses that are not covered by our insurance policies, or if the amount reimbursed is significantly less than our actual losses, our business, financial condition and results of operations could be materially and adversely affected.

Fluctuations in exchange rates could result in foreign currency exchange losses, which may adversely affect our financial condition, results of operations and cash flows.

        We have in the past raised significant funds in U.S. dollars and will receive net proceeds in U.S. dollars from this offering. We have historically incurred substantial short-term borrowings in Renminbi to fund our working capital requirement in the PRC while holding significant U.S. dollar balances. As such, any appreciation in the value of Renminbi against U.S. dollar and other currencies would have a negative impact on our financial position and results of operations. In addition, while we currently incur only a small portion of our expenses and generate only a small portion of our revenue in currencies other than Renminbi, we may incur more of such expenses and generate more of such revenues in the future as we continue our international expansion. As a result, we may be subject to increased foreign exchange rate risk in the future.

        The value of the Renminbi against the U.S. dollar and other currencies may fluctuate and is affected by, among other things, changes in political and economic conditions and the foreign exchange policy adopted by the PRC and other governments. Specifically in the PRC, on July 21, 2005, the PRC government changed its policy of pegging the value of the Renminbi to the U.S. dollar. More recently, from December 31, 2015 to December 31, 2016, the Renminbi depreciated approximately 6.4% against

38
