RISK FACTORS

An investment in our ADSs involves material risks. You should carefully consider the risks and uncertainties set forth below, as well as all of the other information included in this prospectus, before deciding to invest in our ADSs. The occurrence of any of the following risks could materially and adversely affect our business, financial condition, results of operations and prospects. In any such case, the market price of our ADSs could decline and you could lose all or part of your investment.

Risks Related to Our Business and Industry

If the e-commerce market or the health and wellness industry in China does not grow, or grows more slowly than we expect, demand for our products and solutions could be adversely affected.

Continued demand for our products and solutions depends on whether the e-commerce market and the health and wellness industry in China will continue to grow. The long-term viability and prospects of the online retail business in China remain relatively untested. Our future results of operations will depend on numerous factors affecting the development of the e-commerce industry in China, which may be beyond our control, including:

Additionally, our future results of operations will depend on numerous factors affecting the development of the health and wellness industry in China, including:

If consumer utilization of e-commerce channels in China does not grow, or grows more slowly than we expect, demand for our products and services would be adversely affected, our revenues would be negatively impacted and our ability to pursue our growth strategies would be compromised.

We may not be able to effectively manage the expansion of our business or optimally implement our business strategies.

To realize our mission of providing comprehensive health and wellness solutions to our consumers, we have expanded our business, and plan to continue expanding our business. We have been widening our relationships with existing brand partners to include more offerings, procuring new brand partners with different products, improving our logistic and fulfillment capabilities to support our expanded offering and growing through acquisitions of complementary businesses. This expansion has contributed to a heightened level of complexity of our business, in terms of both the type and scale of our operations, which may place a significant strain on our operational, financial and technical resources and increase demands on our management and employees. We cannot assure you that we will be able to manage our expansion successfully, and failure to do so may materially and adversely affect our business, financial condition and results of operations.

17

We are also continuously executing a number of growth initiatives, strategies and operating plans designed to enhance our business, including launching various new services, such as our XG Health platform, an integrated family health management and service platform. The anticipated benefits from these efforts are based on assumptions that may prove to be inaccurate. Moreover, we may not be able to successfully complete these growth initiatives, strategies and operating plans and realize all of the benefits that we expect to achieve, such as expanding our product and service offerings, expanding our offline channel coverage, and strengthening our XG Health platform, or it may be more costly to do so than we anticipate. In addition, profitability, if any, in the new areas that we expand into may be lower than in our existing business, and we may not be successful enough in these newer areas to recoup our investments in them. If any of these circumstances were to occur, our business, financial condition and results of operations may be materially and adversely affected.

If we fail to anticipate evolving consumer preferences for health and wellness products and/or fail to cater effectively to consumer demands, our ability to attract and retain customers may be materially and adversely affected.

Our ability to attract and retain our consumers depends largely on our ability to offer health and wellness products that they find attractive. The success of our business relies on our ability to anticipate changes in consumer preferences, demographic shifts in our consumer base and broader evolving trends in the industry, and to respond to such changes in a timely and cost-effective manner. If we rely on misleading industry intelligence or consistently misinterpret the consumer data we collect, we may fail to cater to the preferences of our consumers or fail to continue to retain our consumers. Consequently, our business, financial condition and results of operations may be materially and adversely affected.

Our success depends on our ability to maintain relationships with existing brand partners, and develop relationships with new brand partners.

Our success is closely tied to our relationships with our existing brand partners, who supply the products that we sell through various platforms. We also identify and target potential new brand partners whose products complement our established inventory or that represent new opportunities for us to meet consumer demand. Many of our brand partners deal with us on a non-exclusive basis, and a number of our brand partner relationships are relatively recent, having been established over the last three years. Because of these factors, we face, and expect to continue to face, constant and intense competition for the business of our brand partners from other Chinese distributors in the health and wellness market. Our relationships with our brand partners may weaken and we may lose our market share if our competitors offer their services to them. The e-commerce market is characterized by rapid technological developments and frequent changes in regulation, specifications and other requirements for how our brand partners should sell their merchandise through particular channels. This could negatively affect our ability to retain existing brand partners and attract new brand partners, our future financial and operating results, and our potential for growth. If we are unable to maintain these relationships or enter into advantageous new arrangements through our targeted approaches to specific potential brand partners, our ability to attract new brand partners may decrease.

In addition, a small number of brand partners contribute a significant portion of our total revenues. For example, in 2018 and the six months ended June 30, 2019, the single largest brand partner in terms of the revenue contribution of its products accounted for 14.6% and 14.8%, respectively, of our total revenues. In the same periods, the ten largest brand partners in terms of the revenue contribution of their products, in the aggregate, accounted for 67.6% and 75.5%, respectively, of our total revenues. Moreover, five of the ten largest brand partners in terms of revenue contribution in the six months ended June 30, 2019 are under the common control of a global food and beverage company. While our relationships with these five brand partners were developed independently and they are each managed by a dedicated operations team, we cannot assure you that failure to maintain a satisfactory relationship with one of these brand partners will not adversely affect our reputation with the other brand partners under common control. Furthermore, the loss of one or more of our largest brand partners may result in a material and adverse effect on our financial condition and results of operation.

18

In such a rapidly changing market, the needs of our brand partners are also constantly evolving to keep pace with consumer demands. If we fail to respond to the evolving needs of our brand partners, our continuing relationships with existing brand partners, our reputation and the demand for our services may be adversely affected. This may have a material and adverse impact on our business, financial position and results of operations.

We may be unable to compete effectively against stronger and better-resourced e-commerce companies, offline competitors or new entrants to the health and wellness market, and may lose market share as a result.

The health and wellness market is intensely competitive in China. We may not be able to command the same price for our services and solutions or we may face a decrease in our market share, which may affect our future financial and operating results, and our ability to grow our business. In addition, competition may intensify if our competitors increase their resources and product range and if established companies in other market segments or geographic markets expand into our market segments or geographic markets. If we cannot compete successfully, our business, financial condition and operating results could be materially and adversely affected.

We face competition in a number of areas. We compete to attract, engage and retain consumers based on the variety, value and personalization of the products and services we offer, and overall user experience and convenience. We compete to attract and retain brand partners based on our scale of operation and the capability of engaging consumers, the sales and growth solutions offered to brand partners as a result of our consumer and industry analysis and the efficiency of our logistics infrastructure in facilitating the delivery of our brand partners’ products to consumers. We also compete for experienced and effective talent and personnel, who serve critical functions in the development of our products and our ecosystem.

Our ability to compete effectively depends on a number of factors, some of which may be beyond our control, including brand partners choosing to develop in-house e-commerce platforms or infrastructure, offline competitors with a broader product range, e-commerce channels deciding to directly compete with us and consolidations within the Chinese health and wellness industry that may result in stronger competitors.

If we are not able to compete effectively, we may lose market share and face a decrease in consumer engagement and sales, which could materially and adversely affect our business, financial condition and results of operations as well as our reputation.

Some of our current or future competitors may have, or may develop, greater brand recognition, better supplier relationships, larger customer bases or greater financial, technical or marketing resources than us. Any smaller companies or potential new entrants to the Chinese health and wellness market may be acquired by, receive investment from or enter into strategic relationships with well-established and well-financed companies or investors which may enhance their competitive positions. Some of our competitors may be able to secure more favorable terms from suppliers, devote greater resources to marketing and promotional campaigns, adopt more aggressive pricing or inventory policies and devote substantially more resources to their technology and infrastructure systems than us. We cannot be certain that we will be able to compete successfully against current or future competitors, and competitive pressures may have a material adverse effect on our business, financial condition and results of operations.

We may need additional capital but may not be able to obtain it on acceptable terms, or at all.

In order for us to grow, we need significant amount of working capital to fund our inventory. In addition, we may require additional capital in case of operating losses as well as any investments or acquisitions we may decide to pursue. For example, the net cash we used in operating activities reached US$40.8 million in 2018 and US$12.7 million in the first six months of calendar year 2019. Such amount may continue to increase due to the expansion of our business and the corresponding increase in inventory. See “— If we fail to effectively manage our inventory, our reputation, results of operations and financial condition may be materially and adversely affected”.

19

If our cash resources are insufficient to satisfy our cash requirements, we may seek to issue additional equity or debt securities, including convertible notes, or obtain new or expanded credit facilities.

Our ability to obtain external financing in the future is subject to a variety of uncertainties, including our future financial condition, results of operations, cash flows, share price performance, liquidity of international capital and lending markets and the PRC governmental regulations over foreign investment and the health and wellness industry. Any debt financing, if available, may involve restrictive covenants and could restrict our operational flexibility and reduce our profitability. In addition, incurring indebtedness would subject us to increased debt service obligations. There can be no assurance that financing would be available in a timely manner or in amounts or on terms acceptable to us, or at all. Any such failure could severely restrict our liquidity as well as have a material adverse effect on our business, financial condition and results of operations. Moreover, any issuance of equity or equity-linked securities could result in significant dilution to the interests of our existing shareholders.

If we are unable to obtain increased financing, any resultant cash flow shortage may materially affect our ability to procure products from our brand partners and meet our financial obligations, which may damage our reputation and brand partner relationships. Such damage to our reputation or relationships would have a material and adverse effect on our business, financial condition and results of operations.

We depend on key management as well as experienced and capable personnel generally, and any failure to attract, motivate or retain our staff could hinder our ability to maintain and grow our business.

Our future success depends substantially upon the continued service of our key executives and other key employees, particularly our co-founders, Ms. Wang and Mr. Zeng. If we lose the services of any member of 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.

The size and scope of our ecosystem also require us to hire and retain a wide range of experienced and capable personnel who can adapt to a dynamic, competitive and challenging business environment. We will need to continue to attract and retain experienced and capable personnel at all levels as we expand our business and operations. Competition for such talent is intense, and the availability of suitable and qualified candidates in the PRC is limited. This high level of competition could compel us to offer higher compensation and other benefits to attract and retain the right candidate. Even if we were to offer higher compensation and other benefits, there is no assurance that these individuals will 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.

We are subject to evolving regulatory requirements, non-compliance with which, or changes in which, may adversely affect our business and prospects.

As a provider of an e-commerce platform for health and wellness products, we are subject to legal and regulatory requirements applicable to multiple industries in the PRC. These industries primarily include the internet and health and wellness industries. We have been subject to penalties by PRC regulatory authorities in the past due to our failure to comply with their requirements, including those in relation to pricing.

The regulations to which we are subject in this area are new and evolving. As a result, the interpretation of these laws and their enforcement is often uncertain. Predicting the application of these laws can be difficult, and unexpected outcomes in the interpretation and enforcement of the applicable regulations may have an adverse impact on our business and operations. Additionally, any future changes in regulation may render our business non-compliant or require changes to our business practices or licensing arrangements to ensure compliance. These changes may involve significant costs, which in turn may adversely affect our business and prospects.

Various regulatory authorities of the PRC government regulate value-added telecommunications services, food business, pharmaceutical operations and services, online drug and medical device operations and online

20

trading and e-commerce. Violations of regulations may lead to the imposition of significant penalties which may affect our business, operations, reputation and financial prospects. In respect of the healthcare industry, in particular, any violation of the relevant laws, rules and regulations may result in harsh penalties and, under certain circumstances, lead to criminal prosecution. See—“Regulation” for details.

As we introduce new products and services to our customers, we may be required to comply with additional laws and regulations that are yet to be determined. To comply with such additional laws and regulations, we may be required to obtain necessary certificates, licenses or permits, as well as expend additional resources to monitor regulatory and policy developments. Our failure to adequately comply with such additional laws and regulations may delay, or possibly prevent, some of our products or services from being offered to users, which may have a material adverse effect on our business, financial condition and results of operations.

Additionally, the PRC has enacted laws and regulations governing internet access and the distribution of products, services, news, information, audio-video programs and other content through the internet. The PRC government has prohibited the distribution of information through the internet that it deems to be in violation of PRC laws and regulations. If any of the information disseminated through our marketplaces and websites were deemed by the PRC government to violate any content restrictions, we would not be able to continue to display such content and could become subject to penalties, including confiscation of income, fines, suspension of business and revocation of required licenses, which could materially and adversely affect our business, financial condition and results of operations. See—“Regulation” for details.

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 sold on our platform.

Due to several high-profile consumer complaint incidents that have occurred in China in recent years and attendant media and advocacy group attention, there has been increased governmental focus in the PRC on consumer protection. Operators of e-commerce marketplaces and platforms are subject to certain provisions of consumer protection laws even where such operator is not the seller of the product or service purchased by the consumer. In addition, if we do not take appropriate remedial action against sellers or service providers 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 and severally liable with the seller or service provider for such infringement.

Moreover, applicable PRC consumer protection laws hold that trading platforms will be held liable for failing to meet any undertakings such platforms make to consumers with regard to products listed on their websites. Furthermore, we are required to report to the State Administration for Market Regulation, or the SAMR, or its local branches any violation of applicable laws, regulations or SAMR rules by sellers or service providers, such as sales of goods without proper license or authorization, and to take appropriate remedial measures, including ceasing to provide services to such sellers or service providers. If claims are brought against us under any of these laws, we could be subject to damages and reputational damage as well as action by regulators, which could have a material adverse effect on our business, financial condition and results of operations.

We do not maintain product liability insurance for products and services transacted on our platform, and any other insurance policies may not cover us, adequately or at all, for any liability we may incur. Even unsuccessful claims could result in the expenditure of funds and management time and resources and could materially reduce our net income and profitability.

If counterfeit products are distributed by us, our reputation and financial results could be materially and adversely affected.

We source health and wellness products from reputable brand partners. However, their measures of safeguarding against counterfeit products may not be adequate. In addition, we engage third-party warehousing

21

and logistics service providers and third-party couriers to conduct product fulfillment, and we may not be able to detect and prevent all potential instances of misconduct or negligence committed by them or by our employees involved in the fulfillment process. If counterfeit products are distributed by us, we may suffer reputational damage. If we are deemed to have participated or assisted in infringement activities associated with counterfeit products, we may be subject to sanctions under applicable laws and regulations, which may include injunctions to cease infringing activities, rectification, compensation, administrative penalties and even criminal liability, depending on the gravity of such misconduct. Furthermore, counterfeit products may be defective or inferior in quality as compared to authentic products and may pose safety risks to consumers. If consumers are injured by counterfeit products distributed by us, we may be subject to lawsuits, severe administrative penalties and criminal liability. See “– 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 sold on our platform.”

If we fail to effectively manage our inventory, our reputation, results of operations and financial condition may be materially and adversely affected.

In order to operate our business effectively and meet our consumers’ demands and expectations, we must maintain a certain level of inventory to ensure prompt deliveries when required. We determine the levels of inventory we hold on the basis of our experience, assessment of consumer demand in a certain period of time and the lead time required to have the inventory in our warehouse.

We forecast consumer demand by relying on a number of factors, including:

We use such metrics to forecast consumer demand more accurately and thereby optimize our inventory management in terms of product portfolio and volume.

However, forecasts are inherently uncertain, and demand for products can change significantly between the inventory order date and the projected sale date. In addition, the acquisition of certain types of inventory may require significant lead time and prepayment and they may not be returnable. Moreover, we normally do not have the right to return unsold items to our suppliers, save for in a limited range of circumstances, such as in the case of quality defects, as set out in our supply agreements.

If we overestimate demand for our products, we may be exposed to increased inventory risks due to accumulated excess inventory. Prolonged periods of excess inventory may lead to pressures on our warehousing system and fulfillment capabilities, increases in inventory holding costs and the risk of inventory obsolescence. In addition, if we fail to manage our inventory effectively we may experience a decline in inventory values and significant inventory write-downs or write-offs due to product expiration. Moreover, we may be required to lower sale prices in order to reduce inventory levels, which may lead to lower gross margins. Conversely, if we underestimate demand for our products, or if our brand partners fail to supply quality products in a timely manner, we may experience inventory shortages, which might result in lost revenues and diminished consumer satisfaction, which could harm our business and reputation.

Any of the above may materially and adversely affect our results of operations and financial condition. As we plan to continue to expand our product offerings, we may continue to face challenges in effectively managing our inventory.

22

Any interruption in our product inventory or fulfillment operations may have an adverse impact on our business.

Our ability to process and fulfill orders accurately depends on the efficient operation of our fulfillment and logistics network and our ability to accurately take orders through the various platforms on which we distribute products and our ability to fulfill such orders. Our fulfillment and logistics infrastructure, including our warehousing facilities and transportation services, may be vulnerable to damage caused by fire, flood, power outage, telecommunications failure, break-ins, earthquake, human error and other events. If any of our fulfillment and logistics infrastructures were to be rendered incapable of operations, then we may be unable to fulfill any orders. We do not carry business interruption insurance, and the occurrence of any of the foregoing risks could have a material adverse effect on our business, prospects, financial condition and results of operations.

Our results of operations are subject to fluctuations due to the seasonality of our business and other events.

We have experienced and expect to continue to experience seasonal fluctuations in our financial performance. These seasonal patterns have caused and will continue to cause fluctuations in our operating results. Historically, we have recorded stronger performance in the fourth quarter, primarily because consumers increase their purchases during e-commerce festivals in China, such as the periods around Singles Day (which is an online sales promotion event that falls on November 11 of each year) and Double Twelves (which is another online sales promotion event that falls on December 12 of each year). In addition, we generally experience a lower level of sales activity in the first quarter due to the Lunar New Year holiday, during which the volumes of online purchases and logistical operations drop significantly due to vacations and business closures.

In anticipation of increased sales activity prior to shopping festivals, we increase our inventory levels and incur additional expenses such as procuring additional working capital and increasing the size of our workforce on a temporary basis. If our seasonal sales patterns become more pronounced in the future, this may strain our personnel, customer service operations, fulfillment operations and shipment activities and may cause a shortfall in revenues compared to expenses in a given period. As a result, our financial results may be materially and adversely affected. In addition to increasing our own inventory levels, we also rely on our brand partners to increase their inventory levels to match projected seasonal demand. If we and our brand partners do not increase inventory levels for popular products in sufficient amounts or if we are unable to restock popular products from our brand partners in a timely manner, we may fail to fulfill customer demand. This may harm our reputation and damage the trust that consumers have in our business, which is a key part of our business model. As a result, we may experience a material and adverse effect on our financial conditions and results of operations.

Our dependence on a small number of e-commerce channels could adversely affect our business or results of operations.

We depend on a small number of e-commerce channels to sell products to consumers. As a result, we derive a substantial portion of our revenue from activity on these channels. For example, sales on Alibaba’s Tmall platform contributed 34% of our total net revenue for the year ended December 31, 2018 and 21% of our total net revenues for the six months ended June 30, 2019.

If the sales on e-commerce channels in China do not grow or grow more slowly than we expect, demand for our products would be adversely affected, our revenues would be negatively impacted, and our ability to pursue our growth strategy would be compromised. Moreover, if the e-commerce channels that we rely on are not successful in attracting consumers or their reputations are adversely affected for any reason, we may experience reduced demand for our products.

Our business may be harmed if the e-commerce channels we rely upon decide to make significant changes to their respective business models, policies, systems or plans. Currently, large e-commerce channels influence to a certain extent terms that affect our profitability and financial condition, including the return policies we offer and the sharing of marketing expenses and payables or receivables between the e-commerce channels and us. We may not be able to negotiate such policies or agreements on terms most favorable to us in the future.

23

In addition, we cannot guarantee that we will be able to access such e-commerce channels in the long term. If we fail to maintain our relationships with such channels, they may decide at any time and for any reason to significantly limit our ability to integrate our solutions with their platforms. Given that online retail in China is dominated by a few large e-commerce channels, we may not be able to adapt or build new relationships on terms favorable to us with any other emerging channels.

Any of the above may adversely affect our revenue, financial condition and results of operations.

We use third-party couriers to deliver orders. If these couriers fail to provide reliable delivery services at commercially acceptable terms, our business and reputation may be materially and adversely affected.

We maintain cooperation arrangements with third-party couriers to deliver our products to our customers. We rely on a select number of third-party delivery services, for example Cainiao, the primary deliverer of cross-border sales through the Tmall platform. In 2018 and the six months ended June 30, 2019, Cainiao was paid 39% and 32%, respectively, of our third-party delivery fees, and the goods delivered by Cainiao accounted for 19% and 12%, respectively, of our revenue in the same periods. As such we may face adverse consequences if there are interruptions to, or failures in, these third parties’ delivery services. Such interruptions or failures could prevent the timely or proper delivery of our products to consumers, eroding consumer confidence and reducing repeat orders. These interruptions may be due to events that are beyond our control or the control of these delivery companies, such as inclement weather, natural disasters, transportation disruptions or labor unrest. While we may claim compensation for disruptions under our standard agreements with third-party delivery services, such claims are subject to a complicated review process and we cannot provide assurance that any compensation payments would make up for the lost consumer goodwill. Also, any significant increase in delivery fees charged by these third parties may result in significant increase in our online distribution expenses. If we fail to find other reliable third-party couriers at commercially acceptable terms, our profitability may be harmed.

In addition, if our third-party couriers fail to comply with applicable PRC rules and regulations, our delivery services may be materially and adversely affected. We may not be able to find alternative delivery companies to provide delivery services in a timely and reliable manner, or at all. Delivery of our products could also be affected or interrupted by the merger, acquisition, insolvency or government shut-down of the delivery companies we engage to make deliveries. If our products are not delivered in proper condition or on a timely basis, our reputation could suffer and we may experience a material adverse effect on our financial condition and results of operations.

We have adopted favorable return policies with certain customers and a higher-than-expected rate of returns could materially and adversely affect our results of operations and financial condition.

In certain instances, we sell the products of our brand partners to third-party e-commerce platforms, which in turn sell those products to consumers. We have adopted contractual product return policies with certain of these third-party e-commerce platforms. These return policies are generally favorable to the third-party e-commerce platforms, and provide in certain cases that products may be returned in unlimited quantities and without cause, albeit subject to a limited return period. If we experience a higher-than-expected rate of returns from these third-party e-commerce platforms, this may result in wastage, overstock and monetary loss, which may materially and adversely affect our financial condition and results of operations.

In addition, we may from time to time be required to amend our existing return policies or implement new return policies pursuant to changes in applicable laws and regulations, which may lead to a larger group of customers being able to take advantage of our return policies, potentially resulting in increased costs. If our return policy is misused, we may experience significantly increased costs which may materially and adversely affect our financial condition and results of operations. If we seek to set limits on such return policies in order to reduce costs, the reaction from our customers may be negative, which may materially and adversely affect our reputation, and results of operations.

24

Any damage to our reputation, including negative publicity against us or our brand partners, may materially and adversely affect our business operations and prospects.

We have cultivated a reputation of trustworthiness and excellence among our brand partners and the consumers. We believe that our reputation is a key reason for consumers to make purchases, and for brand partners who choose us to distribute their products and provide them with market insights and strategies. As a result, we depend on our reputation for the continued success of our business operations and for generating revenue. However, we cannot be certain that we will be able to maintain our positive reputation in the future. Our reputation may be materially and adversely affected by a number of factors, many of which are beyond our control, including:

Any damage to our reputation as a result of these or other factors may cause our products to be perceived unfavorably by consumers, existing or potential brand partners or the Chinese health and wellness market in general, which may materially and adversely affect our reputation, results of operations and financial position.

If our brand partners develop sophisticated knowledge of the Chinese health and wellness market, or increase their in-house e-commerce capabilities, demand for our solutions and services may be adversely affected.

Our brand partners value our solutions and services because of our ability to assist with marketing their products to the Chinese health and wellness market. This ability is founded on our extensive experience in, and local knowledge of, the Chinese health and wellness market, and our technical proficiency in connecting our brand partners to end consumers in China. If our brand partners significantly develop their local expertise and market knowledge, or choose to sell their products directly through third-party e-commerce platforms, our solutions and services may become less important or attractive to our brand partners, and demand for our solutions and services may decline. This may cause a decrease in customer retention and revenue, materially and adversely affecting our business, financial condition and results of operations.

We may be liable for any false or misleading statements or representations made by the healthcare experts on our XG Health platform.

We may be held liable for any false or misleading statements or representations made by the healthcare experts on our XG Health platform. When these healthcare experts publish health management plans, respond to consumer inquiries and make health and wellness recommendations, they may make false or misleading statements or representations in relation to the suitability, effectiveness, use or potential side effects of such plans or products. These healthcare experts may also be negligent in their observations or fail to specify that their recommendation is general in nature and may not apply to the circumstances of particular consumers. We may not always have appropriate disclaimers in place on our XG Health platform.

We may be subject to legal proceedings and claims from time to time where these statements or representations are found to result in harm to our customers. These claims and legal proceedings may be expensive and time-consuming to investigate and defend and may divert resources and management attention from the operation of our business. Although these claims may not be successful, they may harm our reputation and reduce our ability to attract customers and users.

25

Changes in international trade policies and international barriers to trade, or the escalation of trade tensions, may have an adverse effect on our business and expansion plans.

Recent international trade disputes and the uncertainties created by such disputes may disrupt the transnational flow of goods and significantly undermine the stability of the global and Chinese economy, thereby harming our business.

Changes to trade policies, treaties and tariffs in the jurisdictions in which we operate, or are contemplating operating, or the perception that these changes could occur, could adversely affect the financial and economic conditions in such jurisdictions, as well as our international and cross-border operations, our financial condition and results of operations. The U.S. administration under President Trump has advocated greater restrictions on trade generally, imposed and significantly increased tariffs on certain goods imported into the United States, particularly from China, and has recently taken steps toward restricting trade in certain goods. Among the goods currently subject to tariffs are items which form part of the healthcare and supplement supply chain, including certain chemicals used in the manufacture of healthcare supplements. These trade developments could materially impact our business as certain of our brand partners are based in the United States, and thus may face increased difficulty in sourcing base ingredients for their products, or cost-effectively developing new products with restricted or more expensive base ingredients. As a result, we may face an increase in our operating costs as our suppliers raise their prices to absorb their increased costs, or an inability to meet the demands of the consumers who purchase from us, and a resulting decrease in our profits.

The PRC has taken several measures in response to these U.S. administration trade policies. For example, the PRC has increased tariffs on certain goods from the United States, the total value of which is US$110 billion.

Such tariffs could have an adverse effect on our ability to source products from certain of our United States based partners, either at an acceptable cost or at all, to sell in China. If the products of our brand partners become subject to increased tariffs or other trade barriers, the resultant increase in cost or difficulty of importation may force us to find alternative providers of comparable products. We cannot be certain that these alternative providers would be acceptable to Chinese consumers, given that the level of trust in the brands that we supply is a primary driver of purchasing decisions made by Chinese consumers. As a result, we may experience a decrease in demand, and a material and adverse effect on our financial condition and results of operations.

Therefore, any escalation in existing trade tensions or the advent of a trade war, or news and rumors of the escalation of a potential trade war, could affect the supply chains of participants within our ecosystem, increase their and our costs and have a material adverse effect on our business, results of operations and, ultimately, the trading price of our ADSs.

Exchange rate fluctuations may negatively affect our results of operations.

We source our products from brand partners globally. We purchase these products primarily using U.S. dollars, and these products are ultimately sold to the Chinese domestic market, whose participants primarily make their purchases in Renminbi. There is ordinarily a temporal gap between the point at which we purchase products and the point at which we receive payment for the products sold. As a result, we are subject to the fluctuations of the currency exchange markets, particularly in the value of RMB to the U.S. dollar. If the value of Renminbi declines during the temporal gap relative to the U.S. dollar, we may face a lower profit margin, or in some cases a loss, on the products sold.

In addition, substantially all of our operating expenses are denominated in Renminbi, and a significant portion of our financial assets are also denominated in Renminbi while a significant portion of our debt is denominated in U.S. dollars. We are a holding company and we rely on dividends paid by our operating subsidiaries in China for our cash needs. Any significant revaluation of the Renminbi may materially reduce any dividends payable on our ADSs in U.S. dollars. To the extent that we need to convert U.S. dollars we receive

26

from this 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. Conversely, if we decide to convert our Renminbi into U.S. dollars for the purpose of making payments for dividends on our Class A ordinary shares or ADSs 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 we would receive. As such, currency fluctuations may materially and adversely affect our financial condition and results of operations.

Any failure to comply with PRC regulations regarding advertising may subject us to civil claims, fines and other legal or administrative sanctions.

PRC advertising laws and regulations require the content of advertisements to be fair, accurate, not misleading and in full compliance with applicable laws. The Provisional Regulation on the Release of Food Advertisements, released by the SAIC on December 30, 1996 and amended on December 3, 1998, prohibits advertisers from expressly or impliedly indicating the healthcare effects of ordinary foods. In addition, the content of healthcare food advertisements must follow the specifications and the label approved by the health administrative authorities of the State Council. We have made efforts to ensure our advertisements and related advertising practices are in compliance with applicable regulations. However, we cannot assure you that we have fully complied with the requirements of PRC regulatory authorities or will be able to fully comply with the requirements of PRC regulatory authorities regarding advertising. If we are found in violation of applicable advertising laws and regulations, we may face serious penalties including fines, revocation of our business licenses and discontinuance of our advertising activities. As a result, we may not be able to publish new advertisements in a timely manner, and our turnover and reputation could be materially affected. Moreover, governmental actions and civil claims may be filed against us for misleading or inaccurate advertising. We may have to spend significant resources in defending against such actions, and these actions may damage our reputation, result in reduced turnover, and negatively affect our results of operations.

We may not be able to conduct our marketing activities effectively, properly, or at reasonable costs.

We conduct a variety of marketing and brand promotion efforts designed to enhance our brand recognition and increase sales of our products. However, our brand promotion and marketing activities may not be well received and may not result in the levels of sales that we anticipate. Additionally, marketing approaches and tools in the Chinese health and wellness market are continually evolving, which may further require us to experiment with new marketing methods to keep pace with industry developments. Failure to refine our existing marketing approaches or to introduce new marketing approaches in a cost-effective manner may materially and adversely affect our financial condition and results of operations.

We are subject to limitations in promoting our products, which may have an impact on our business operations.

We are subject to certain limitations in promoting products. The healthcare experts we work with and other relevant parties in the provision of our health and wellness content may have to comply with rules and regulations that restrict the promotion or dissemination of certain healthcare related information, such as information on the professional healthcare services and practice provided by licensed medical practitioners. Such restrictions may affect our ability to further enhance our brand recognition or secure new business opportunities in the future.

There can be no assurance that our existing practices of monitoring our content dissemination process and publication would continue to be effective and would comply fully with laws and regulations. Should there be any change in the relevant rules and regulations, or change of interpretation thereof, we, the healthcare experts we work with and other relevant third parties may be regarded as breaching the relevant rules and regulations and may be subject to regulatory penalties or disciplinary actions, which may materially and adversely affect our business and reputation.

27

Our own information technology systems and infrastructure could fail or be subject to disruption.

Our platform depends on the efficient and uninterrupted operation of our computer and communications systems. Substantially all of our computer hardware and our cloud computing services are currently located in China. In addition, we retain substantial quantities of data relating to transactions, consumer information and other data that enables the operation and management of online stores. Although we have prepared for contingencies through redundancy measures and disaster recovery plans, such preparation may not be sufficient and we do not carry business interruption insurance.

Despite any precautions we take, the occurrence of a natural disaster, such as an earthquake, flood or wildfire, or other unanticipated problems at our facilities in China, including power outages, telecommunications delays or failures, break-ins to our systems or computer viruses, could result in delays or interruptions to our website or other portions of our platform, loss of data and significant business interruption. Any of these events could damage our reputation, significantly disrupt our operations and subject us to liability, which could adversely affect our business, financial condition and results of operations.

Security breaches and attacks against our systems and network, and any potentially resulting breach or failure to otherwise protect confidential and proprietary information could adversely affect our business, reputation, financial condition and results of operations.

Any failure to maintain the satisfactory performance of our XG Health platform could materially and adversely affect our business and reputation.

The satisfactory performance, reliability and availability of our XG Health platform are important to our success. Certain adverse technological events may, individually or collectively, materially and adversely affect our business, reputation, financial condition and results of operations. Such adverse events include, but are not limited to, system interruptions caused by latent flaws in the technology underpinning our platform, communication and system failures including failure of third-party platform or payment systems on which we rely, errors encountered during system upgrades or system expansions, computer viruses, hacking or other attempts to harm our systems. We can provide no assurance that our current security mechanisms will be sufficient to protect our systems from such adverse events. Any such adverse events could materially and adversely affect our business, reputation, financial condition and results of operations.

We may experience system interruptions if too many consumers attempt to access our XG Health platform within a short period of time due to promotions or other increases in demand. Such interruptions may make our platform unavailable or cause our platform to perform sub-optimally, which may prevent us from transmitting orders to our fulfillment operations, reducing the volume of transactions on our platform as well as its attractiveness to consumers. As a result, we may experience a material and adverse effect on our business, financial condition and results of operations due to lost revenue.

In order to support our business and facilitate its growth, we must continue to improve the technology underpinning our platform and ensure that timely upgrades are carried out in accordance with our improvement strategies. Despite our best efforts, we cannot be certain that we will be successful in executing these system upgrades and improvement strategies. In particular, our systems may experience disruptions during upgrades, and the new technologies or infrastructures may not be fully integrated with the existing systems on a timely basis, if at all, or compatible.

28

Our business generates and processes a large amount of data, and the improper use or disclosure of such data could harm our reputation as well as have a material adverse effect on our business and prospects.

Our business collects and processes a large quantity of personal, transaction and behavioral data. We face risks in the handling and securing of these large volumes of data. In particular, we face a number of challenges relating to data from transactions and other activities on our platform, including:

Any systems failure or security breach or lapse 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.

As we expand our operations, we may be subject to additional laws in other jurisdictions where our brand partners, consumers and other participants are located. The laws, rules and regulations of other jurisdictions may impose requirements and penalties that are more stringent than, or conflict with, those under PRC law, compliance with which could require significant resources and costs. Our privacy policies and practices concerning the collection, use and disclosure of user data are located on our websites and on our XG Health platform. Any failure, actual or perceived, by us to comply with our posted privacy policies or 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 may subject us to significant penalties and negative publicity and require us to change our business practices. Any such occurrence could increase our costs and materially and adversely affect our reputation, financial condition and results of operations. See—“Regulation” for details.

If the contents we distribute or the online interaction we offer are deemed by the relevant authorities in the PRC to be in the nature of medical rather than non-medical, we may be subject to additional regulations and incur substantial compliance cost, and our business prospects, results of operations and financial conditions may be adversely affected.

The distribution of medical information and medical advertisements are subject to PRC regulations. Any website operator that provides medical information services must obtain certain licenses and approvals by relevant authorities before engaging in such businesses in the PRC. We believe it is improbable for PRC governmental authorities to deem the contents distributed by us to be medical information or medical advertisements, and we have not been subject to any regulatory authority’s inquiries or investigations in connection with the content displayed on our platforms. However, if certain information displayed on our XG platform or otherwise distributed by us is considered medical information or medical advertisement by relevant authorities, it will subject us to additional regulations. As a non-medical health and wellness integrated solution provider, we do not possess the required licenses or approvals. Consequently, if required by relevant authorities, we may need to scale back, rearrange or alter the content of information displayed on our platforms.

In addition, online medical consultation in the PRC requires medical service providers to be associated with approved physical hospitals and such providers to obtain regulatory approvals and licenses. We have not yet acquired or established a hospital, and thus are not licensed to provide online medical consultation. If certain consultation services offered on our XG platform is considered online medical consultation by relevant authorities, such services may be suspended until we acquired or established our own hospital and obtained necessary approvals and licenses.

29

Therefore, if the contents we distribute or the online interaction we offer are deemed to be in the nature of medical, our business model may be affected, and substantial compliance cost may be incurred. As a result, our business prospects, results of operations and financial conditions may be adversely affected.

Substantial uncertainties exist with respect to the PRC Cyber Security Law and cybersecurity regulations, including any impact it may have on our business operations.

On November 7, 2016, the PRC enacted its Cyber Security Law, which took effect on June 1, 2017, to establish more stringent requirements applicable to operators of computer networks, especially to operators of networks which involve critical information infrastructure. Because of its exceptional breadth in scope, ambiguous requirements and broadly defined terminology, we are concerned about the law’s potential impact on our operations in China, particularly in relation to the safeguarding of user information. The Cyber Security Law contains an overarching framework for regulating internet security, protection of private and sensitive information, and safeguards for national cyberspace security and provisions for the continued government regulation of the internet and content available in China. The Cyber Security Law emphasizes requirements for network products, services, operations and information security, as well as monitoring, early detection, emergency response and reporting.

Despite the law having taken effect, there remains a high degree of uncertainty in its interpretation and enforcement, especially in terms of protection of personal information. This uncertainty presents a risk for us due to the large volume of personal data that we collect through our various touchpoints. As it is not clear what the law will require in a given scenario nor how these requirements may be interpreted, we cannot assure you that we would be able to comply with such requirements in a timely manner. Failure to comply may lead to fines, orders of rectification, confiscation of illegal gains, revocation of the business permit or license and other government actions, which may materially and adversely affect our business, financial condition and results of operations.

Further, as the legal and regulatory framework for the protection of information in cyberspace in China continues to evolve, we may be required to adjust our business practices or incur additional operating expenses, which may adversely affect our results of operations and financial condition.

The successful operation of our business depends upon the performance and reliability of the internet and telecommunications infrastructures in China.

Our business depends on the reliable performance of the Internet and telecommunications infrastructures in China. Almost all access to the internet is maintained through state-owned telecommunication operators under the administrative control and regulatory supervision of the Ministry of Industry and Information Technology of China. In addition, the national networks in China are connected to the internet through state-owned international gateways, which are the only channels through which a domestic user can connect to the internet outside of China. We may not have access to equivalent or sufficient alternative networks in the event of disruptions, failures or other problems with China’s Internet infrastructure. As this vital infrastructure is state-owned, we are subject to governmental policy which may disrupt supply, and may have fewer avenues of recourse to remedy any losses caused by disruption pursuant to governmental policy. In addition, the internet infrastructure in China might not support the demands associated with continued growth in internet usage.

The failure of telecommunications network operators to provide us with the requisite bandwidth could also interfere with the speed and availability of our websites. We have no control over the costs of the services provided by the national telecommunications operators. If the cost of telecommunications and internet services rise significantly, or if the telecommunication network in China is disrupted or fails, our gross margins could be adversely affected. Technical limitations on internet use could also be developed or implemented. For example, restrictions could be implemented on personal internet use in the workplace in general or access to our platform in particular. This could lead to a reduction of consumer activity or a loss of consumers altogether, which in turn could have an adverse effect on our financial position and results of operations. In addition, if internet access fees

30

or other charges to internet users increase, our user traffic might decrease, which in turn could significantly decrease our revenues and have a material and adverse effect on our financial condition and results of operations.

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

The global macroeconomic environment is facing challenges, including, amongst other things:

Our business and operations are primarily based in China and substantially all of our revenues are derived directly and indirectly from our operations in China. Accordingly, our financial results have been, and are expected to continue to be, affected by the economy in general and the health and wellness market in China in particular. Although the economy in China has grown significantly in the past decades, it is still facing difficulties and has experienced inconsistent growth in recent years.

Economic conditions in China are sensitive to the global economic conditions described above, changes in domestic economic and political circumstances and the expected or perceived overall economic growth rate in China. Any prolonged slowdown in the global or Chinese economy may have an adverse impact on the levels of disposable income of Chinese consumers, and impede the growth of the rising Chinese middle class. As a result, demand for our products, which is strongly driven by members of the Chinese middle class, may be negatively affected. Such a decrease in demand may have a material and adverse impact on our business, results of operations and financial condition.

We may be the subject of anti-competitive, harassing, or other detrimental conduct by third parties including complaints to regulatory agencies, negative blog postings, and the public dissemination of malicious assessments of our business that could harm our reputation and cause us to lose customers and revenues and adversely affect the price of our ADSs.

We may be the target of anti-competitive, harassing, or other detrimental conduct by third parties. Such conduct includes complaints, anonymous or otherwise, to regulatory agencies. We may be subject to government or regulatory investigation as a result of such third-party conduct and may be required to expend significant time and incur substantial costs to address such third-party conduct, and there is no assurance that we will be able to conclusively refute each of the allegations within a reasonable period of time, or at all. Additionally, allegations, directly or indirectly against us, may be posted in internet chat-rooms or on blogs or websites by anyone, whether or not associated with us, on an anonymous basis. Consumers value readily available information concerning retailers, manufacturers, and their goods and services and often act on such information without further investigation or authentication and without regard to its accuracy. The availability of information on social media platforms and devices is virtually immediate, as is its impact. Social media platforms and devices immediately publish the content their subscribers and participants post, often without filters or checks on the accuracy of the content posted. Information posted may be inaccurate and adverse to us, and it may harm our financial performance, prospects or business. The harm may be immediate without affording us an opportunity for redress or correction. Our reputation may be negatively affected as a result of the public dissemination of anonymous allegations or malicious statements about our business, which in turn may cause us to lose market share, customers and revenues and adversely affect the price of our ADSs.

Our business may be materially and adversely affected by adverse news, scandals or other incidents associated with the general health and wellness industry.

Incidents that inspire doubt as to the quality or safety of health and wellness products manufactured, distributed or sold by other participants in the general health and wellness industry in China or around the world,

31

particularly those who primarily operate in the e-commerce space, have been, and may continue to be, subject to widespread media attention. Such incidents may damage the reputation of not only the parties involved, but also the health and wellness industry in general, even if such parties or incidents have no relation to us, our management, our employees, our brand partners, our platform or the third-party e-commerce websites through which we also market products. There may also be a decrease in consumer demand for healthcare related products if these negative incidents diminish the trust of consumers in the Chinese health and wellness market. Such negative publicity, and any resultant decrease in demand for our products and services, may adversely affect our reputation and business operations. In addition, incidents not related to product quality or safety, or other negative publicity or scandals implicating us or our employees, regardless of merit, may also have an adverse impact on our reputation, financial condition and results of operations.

We may not be able to protect our intellectual property rights.

We rely on a combination of trademark, fair trade practice, patent, copyright and trade secret protection laws in the PRC and other jurisdictions in which we hold intellectual property rights, as well as confidentiality procedures and contractual provisions with employees, suppliers and third parties, to protect our intellectual property rights.

Intellectual property protection may not be sufficient in the PRC or in the other jurisdictions in which we hold intellectual property. Confidentiality 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 in the PRC or elsewhere. In addition, policing any unauthorized use of our intellectual property is difficult, time-consuming and costly, and the steps we have taken may be inadequate to prevent the 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 managerial and financial resources. We can provide no assurance that we will prevail in such litigation. In addition, our trade secrets may be leaked or otherwise become available to, or be independently discovered by, our competitors. Any failure in protecting or enforcing our intellectual property rights could have a material adverse effect on our business, financial condition and results of operations.

We may be accused of infringing intellectual property rights of third parties and content restrictions of relevant laws.

Third parties may claim that the technology used in the operation of our platforms infringes upon their intellectual property rights. Although we have not previously faced material litigation involving direct claims of infringement by us, the possibility of intellectual property claims against us increases as we expand. Such claims, whether meritorious or not, may result in injunctions against us, payment of damages and expenditure of significant financial and management resources. If we are found to have infringed the intellectual property rights of third parties in the future, we may need to obtain licenses to continue to operate our platforms and such licenses may not be available on terms acceptable to us or at all. These risks are amplified by the increase in the number of third parties whose sole or primary business is to assert such claims.

We may from time to time become party to litigation, other legal or administrative disputes and proceedings that may materially and adversely affect us.

In the course of our ordinary business operations, we may become a party to litigation, legal proceedings, claims, disputes or arbitration proceedings from time to time. We are currently involved in several lawsuits. For example, in March 2016 we entered into a cooperation framework agreement to establish a joint venture with Shanghai Heng Shou Tang Health Food Co. Ltd., Shanghai Heng Shou Tang Pharmaceutical Co., Ltd. and Mr. Wei Song, or our joint venture partners. As part of the agreement, Shanghai Heng Shou Tang Health Food Co. Ltd. and Shanghai Heng Shou Tang Pharmaceutical Co., Ltd. agreed to contribute their ownership in a number of trademarks to the joint venture. However, only a portion of such trademarks have been transferred to

32

us to date. In October 2018, we filed a civil claim against the joint venture partners in the Shanghai Xuhui People’s Court to enforce the transfer of the remaining trademarks, claim damages in the amount of RMB7.19 million (US$1.05 million) and request that Shanghai Heng Shou Tang Health Food Co. Ltd. and Shanghai Heng Shou Tang Pharmaceutical Co., Ltd. be enjoined from using the brand name “Heng Shou Tang” in all categories. In January 2019, the joint venture partners filed a counterclaim to rescind the agreement and allege damages in the amount of RMB3.25 million (US$472.7 thousand). In July 2019, the Shanghai Xuhui People’s Court ruled that we shall pay damages in the amount of RMB3.25 million (US$472.7 thousand) to the joint venture partners for breaching our contractual obligation to contribute capital to the joint venture, and that the joint venture partners shall continue to perform their contractual obligations by transferring the remaining trademarks to the joint venture and cease to use the brand name “Heng Shou Tang” in all categories. Both we and the joint venture partners have appealed against this ruling. We cannot assure you that the dispute will be resolved in our favor. In the case of an adverse judgment in the appeal, we may be required to cease using the relevant trademarks or pay the monetary damages, and the joint venture may be dissolved, which may adversely affect our results of operations.

Were any proceedings, claims, disputes or arbitration to arise, these may distract our senior management’s attention and consume our time and other resources. In addition, even if we ultimately succeed in such proceedings, there may be negative publicity created in the course of or surrounding that proceeding, which may materially and adversely affect our reputation. In the case of an adverse verdict, we may be required to pay significant monetary damages, assume significant liabilities or suspend or terminate parts of our operations. As a result, our business, financial condition, results of operations and prospects may be materially and adversely affected.

Future strategic alliances or acquisitions may have a material adverse effect on our business, financial condition and results of operations.

We plan to expand our business both geographically and in terms of the products and services that we offer to our customers and brand partners. In pursuit of this strategy, we may enter into strategic alliances, including joint ventures or equity investments, with various third parties to further our business purpose from time to time. These alliances could subject us to a number of risks, including risks associated with sharing proprietary information, non-performance by a third party and increased expenses in establishing new strategic alliances, any of which may materially and adversely affect our business. We may have limited ability to monitor or control the actions of these third parties and, to the extent any of these strategic third parties suffers negative publicity or harm to their reputation from events relating to their business, we may also suffer negative publicity or harm to our reputation by virtue of our association with any such third party.

In addition, when appropriate opportunities arise, we may acquire additional assets, products, technologies or businesses that are complementary to our existing business. In addition to possible shareholders’ approval, we may also have to obtain approvals and licenses from relevant government authorities for the acquisitions and to comply with any applicable PRC laws and regulations, which could result in increased delay and costs, and may derail our business strategy if we fail to do so. Any international operations that we absorb as part of any acquisitions may give rise to risks and challenges that could adversely affect our business, such as compliance with international legal and regulatory requirements, further management of fluctuations in currency exchange rates or competition from local incumbents with superior local market knowledge and competitive advantages. Moreover, we cannot be certain that any international expansion efforts can be completed as planned or achieve the intended results, or that any negative results from acquired interests would not affect our business as a whole.

Furthermore, past and future acquisitions and the subsequent integration of new assets and businesses require significant attention from our management and could result in a diversion of resources from our existing business, which in turn could have a material adverse effect on our business operations. Acquired assets or businesses may not generate the financial results we expect. Acquisitions could result in the use of substantial amounts of cash, potentially dilutive issuances of equity securities, the occurrence of significant goodwill

33

impairment charges, amortization expenses for other intangible assets and exposure to potential unknown liabilities of the acquired business. Moreover, the costs of identifying and consummating acquisitions may be significant. Furthermore, our equity investees may generate significant losses, a portion of which will be shared by us in accordance with U.S. GAAP. Any such negative developments could have a material adverse effect on our business, financial condition and results of operations.

Increases in labor costs in the PRC may adversely affect our business and results of operations.

The Chinese economy has been experiencing increases in inflation and labor costs in recent years. As a result, average wages in China are expected to continue to grow. In addition, various PRC laws and regulations designed to enhance labor protection require us to pay certain statutory employee benefits, including pensions, housing funds, medical insurance, work-related injury insurance, unemployment insurance and maternity insurance to designated government agencies for the benefit of our employees. 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 could be subject to late payment fees, fines and/or other penalties. As the interpretation and implementation of these laws and regulations are still evolving, our employment practices may not at all times be deemed to be in compliance with the applicable laws and regulations. If the relevant authorities determine that we should make supplemental social insurance and housing fund contributions and that we are subject to fines and legal sanctions, our business, financial condition and results of operations could be adversely affected. We expect that our labor costs, including wages and employee benefits, will continue to increase. Unless we are able to pass on these increased labor costs to our customers by increasing the prices of our products and services, our financial condition and results of operations could be adversely affected.

In addition, we may face labor unrest if our employees form the view that we do not pay them adequately or provide adequate working conditions. Such labor unrest may take the form of labor disputes, strike actions or protests against us. This may have a negative impact on our reputation and cause a loss of public trust in our company. If this were to occur, such loss of trust may materially and adversely affect our financial condition and results of operations.

If we fail to maintain proper and effective internal controls, our ability to produce accurate financial statements on a timely basis could be impaired.

As a result of the initial public offering, we expect to become subject to the reporting requirements of the Exchange Act, the Sarbanes-Oxley Act of 2002 and the rules and regulations of the NASDAQ. The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal controls over financial reporting. Following our initial public offering, we will be required to perform system and process evaluation and testing of our internal controls over financial reporting to allow management to report on the effectiveness of our internal controls over financial reporting in our Form 20-F filing for that year, as required by Section 404 of the Sarbanes-Oxley Act. In addition, when we cease to be an “emerging growth company” as the term is defined in the Jumpstart Our Business Startups Act, our independent registered public accounting firm must attest to and report on the effectiveness of our internal control over financial reporting. Our management may conclude that our internal control over financial reporting is not effective. Moreover, even if our management concludes that our internal control over financial reporting is effective, our independent registered public accounting firm, after conducting its own independent testing, may issue a report that is qualified if it is not satisfied with our internal controls or the level at which our controls are documented, designed, operated or reviewed, or if it interprets the relevant requirements differently from us. This will require that we incur substantial additional professional fees and internal costs to expand our accounting and finance functions and that we expend significant management efforts. We may experience difficulty in meeting these reporting requirements in a timely manner.

In the course of preparing and auditing our consolidated financial statements for the years ended December 31, 2017 and 2018, we and our independent registered public accounting firm identified one material

34

weakness in our internal control over financial reporting as of December 31, 2018. In accordance with U.S. GAAP and financial reporting requirements set forth by the SEC, a “material weakness” is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our company’s annual or interim consolidated financial statements will not be prevented or detected on a timely basis.

The material weakness identified relates to our lack of sufficient financial reporting and accounting personnel with appropriate knowledge of U.S. GAAP and SEC reporting requirements to formalize key controls over financial reporting and to prepare consolidated financial statements and related disclosures. Neither we nor our independent registered public accounting firm undertook a comprehensive assessment of our internal control under the Sarbanes-Oxley Act for purposes of identifying and reporting any weakness in our internal control over financial reporting. We are required to do so only after we become a public company. Had we performed a formal assessment of our internal control over financial reporting or had our independent registered public accounting firm performed an audit of our internal control over financial reporting, additional control weaknesses may have been identified. To remedy our identified material weakness subsequent to December 31, 2018, we plan to undertake steps to strengthen our internal control over financial reporting, including: (i) implementing regular and continuous U.S. GAAP accounting and financial reporting training programs for our accounting and financial reporting personnel, (ii) establishing effective oversight and clarifying reporting requirements for non-recurring and complex transactions to ensure consolidated financial statements and related disclosures are accurate, complete and in compliance with SEC reporting requirements, (iii) preparing comprehensive accounting policies, manuals and closing procedures to improve the quality and accuracy of our period-end financial closing process and (iv) preparing comprehensive accounting policies, manuals and closing procedures to improve the quality and accuracy of our period-end financial closing process. However, we cannot assure you that we will remediate our material weakness in a timely manner.

In addition, our internal control over financial reporting will not prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud will be detected.

An occurrence of a natural disaster, widespread health epidemic or other outbreaks could have a material adverse effect on our business, financial condition and results of operations.

Our business could be materially and adversely affected by natural disasters, such as earthquakes, wildfires or floods, the outbreak of a widespread health epidemic or other events, such as wars, acts of terrorism, environmental accidents, power shortage, labor unrest or communication interruptions. The occurrence of such an event in China or elsewhere could materially disrupt our business and operations. Such events could also cause a temporary closure of the facilities we use for our operations, which would severely disrupt our operations and have a material adverse effect on our business, financial condition and results of operations. Our operations could be disrupted if any of our employees were suspected of having any of the epidemic illnesses, since this could require us to quarantine some or all of such employees or disinfect the facilities used for our operations. In addition, our revenue and profitability could be materially reduced to the extent that a natural disaster, health epidemic or other outbreak harms the global or Chinese economy in general. Our operations could also be severely disrupted if our users or other participants were affected by such natural disasters, health epidemics or other outbreaks.

We may not have sufficient insurance coverage.

We have obtained insurance to cover certain potential risks and liabilities, such as property damage. However, insurance companies in China offer limited business insurance products. As a result, we may not be able to acquire any insurance for certain types of risks such as business liability or service disruption insurance

35

for our operations in China, and our coverage may not be adequate to compensate for all losses that may occur, particularly with respect to loss of business or operations. We do not maintain business interruption insurance or product liability insurance, nor do we maintain key-man life insurance. This could leave us exposed to potential claims and losses. Any business disruption, litigation, regulatory action, outbreak of epidemic disease or natural disaster could also expose us to substantial costs and diversion of resources. We cannot assure you that our insurance coverage is sufficient to prevent us from any loss or that we will be able to successfully claim our losses under our current insurance policy on a timely basis, or at all. If we incur any loss that is not covered by our insurance policies, or the compensated amount is significantly less than our actual loss, our business, financial condition and results of operations could be materially and adversely affected.

Failure to renew our current leases or locate desirable alternatives for our leased properties could materially and adversely affect our business.

We lease properties for our offices and the warehousing facilities that we operate. We may not be able to successfully extend or renew such leases upon expiration of the current term on commercially reasonable terms or at all, and may therefore be forced to relocate our affected operations. This could disrupt our operations and result in significant relocation expenses, which could adversely affect our business, financial condition and results of operations.

In addition, we compete with other businesses for premises at certain locations or of desirable sizes. As a result, even though we could extend or renew our leases, rental payments may significantly increase as a result of the high demand for the leased properties. Moreover, we may not be able to locate desirable alternative sites for our current leased properties as our business continues to grow and failure in relocating our affected operations could adversely affect our business and operations.

Certain of our leasehold interests in leased properties have not been registered with the relevant PRC governmental authorities as required by relevant PRC laws and some of our leased properties have title defects.

We have not registered certain of our lease agreements with the relevant government authorities. Under the relevant PRC laws and regulations, we may be required to register and file with the relevant government authority executed leases. The failure to register the lease agreements for our leased properties will not affect the validity of these lease agreements, but the competent housing authorities may order us to register the lease agreements in a prescribed period of time and impose a fine ranging from RMB1,000 (US$145.5) to RMB10,000 (US$1,454.6) for each non-registered lease if we fail to complete the registration within the prescribed timeframe.

In addition, the actual use of some of our leased properties was inconsistent with the planned use on the property ownership certificates. If relevant government authorities require the lessor to correct such inconsistency or request land resumption, we may be unable to continue to lease such properties and as a result we may be forced to relocate the properties and incur additional expenses relating to such relocation. If we fail to find suitable replacement sites in a timely manner or on terms acceptable to us, our business and results of operations could be materially and adversely affected.

Risks Related to Our Corporate Structure

We are a “controlled company” within the meaning of the NASDAQ corporate governance requirements, which may result in public investors having less protection than they would if we were not a controlled company.

Immediately after completion of this offering, our co-founders, Ms. Zoe Wang, who serves as our Chief Executive Officer, and Mr. Leo Zeng, who serves as our Chief Operating Officer will collectively hold             %

36

of the total voting rights in our company, assuming the underwriters do not exercise their option to purchase additional ADSs, and we are, and expect to continue to be immediately after the completion of this offering, a “controlled company” as defined under the NASDAQ Stock Market Rules. As a controlled company, we rely on certain exemptions that are available to controlled companies from the NASDAQ corporate governance requirements.
