Preliminary Prospectus dated                          , 2019

American Depositary Shares

Luckin Coffee Inc.
(incorporated in Cayman Islands)

Representing             Class A Ordinary Shares

---

        This is an initial public offering of American depositary shares, or ADSs, representing Class A ordinary shares of Luckin Coffee Inc.

        We are offering             ADSs. Each ADS represents             of our Class A ordinary shares, par value US$[0.001] per share.

        Prior to this offering, there has been no public market for the ADSs or our shares. It is currently estimated that the initial public offering price per ADS will be between US$             and US$             .

        We have applied for listing the ADSs on the Nasdaq Global Select Market under the symbol "LK."

        We are an "emerging growth company" under applicable U.S. federal securities laws and are eligible for reduced public company reporting requirements.

        See "Risk Factors" beginning on page 14 for factors you should consider before investing in the ADSs.

        Neither the United States Securities and Exchange Commission nor any other regulatory body has approved or disapproved of these securities or passed upon the accuracy or adequacy of this prospectus. Any representation to the contrary is a criminal offense.

---

(1)

See "Underwriting" for additional disclosure regarding compensation payable by us to the underwriters.

        The underwriters have a 30-day option to purchase up to an additional             ADSs from us at the initial public offering price less the underwriting discounts and commissions.

        Immediately upon the completion of this offering, our outstanding share capital will consist of Class A ordinary shares and Class B ordinary shares. Holders of Class A ordinary shares and Class B ordinary shares have the same rights except for voting and conversion rights. Each Class A ordinary share is entitled to one vote; and each Class B ordinary share is entitled to ten votes and is convertible into one Class A ordinary share at any time by the holder thereof. Class A ordinary shares are not convertible into Class B ordinary shares under any circumstances. Upon any sale, transfer, assignment or disposition of any Class B ordinary shares by a holder thereof to any non-affiliate to such holder, each of such Class B ordinary shares will be automatically and immediately converted into one Class A ordinary share. Immediately upon the completion of this offering, the Pre-IPO Shareholders will beneficially own all of our issued and outstanding Class B ordinary shares. Based on an assumed initial public offering price of US$             per ADS, the mid-point of the estimated public offering price range shown on the front cover of this prospectus, these Class B ordinary shares will constitute approximately         % of our total issued and outstanding share capital and         % of the aggregate voting power of our total issued and outstanding share capital immediately upon the completion of this offering, assuming the underwriters do not exercise their over-allotment option.

        The underwriters expect to deliver the ADSs against payment in U.S. dollars in New York, New York on                           , 2019.

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 the 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 the 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

Our limited operating history may not be indicative of our future growth or financial results and we may not be able to sustain our historical growth rates.

        We commenced our operations in October 2017 and have achieved rapid growth since our inception. As of March 31, 2019, we operated 2,370 stores in 28 cities in China and had over 16.8 million cumulative transacting customers. However, our limited operating history may not be indicative of our future growth or financial results. There is no assurance that we will be able to maintain our historical growth rates in future periods. Our growth rates may decline for any number of possible reasons and some of them are beyond our control, including decreasing customer spending, increasing competition, declining growth of China's coffee industry or China's food and beverage sector in general, emergence of alternative business models, or changes in government policies or general economic conditions. If our growth rates decline, investors' perceptions of our business and prospects may be adversely affected and the market price of the ADSs could decline. In addition, since our business model is innovative in China's coffee industry, it increased the difficulty in evaluating our business and future prospects based on our historical operational or financial result.

We have incurred significant net losses since our inception and we may continue to experience significant net losses in the future.

        We have incurred significant net losses since our inception in June 2017. For the period from June 16, 2017 (inception date) to December 31, 2017 and the year ended December 31, 2018, we incurred net losses of RMB56.4 million and RMB1,619.2 million (US$235.5 million), respectively, primarily attributed to the expenses in relation to the startup and fast expansion of our business.

        We intend to further increase our brand awareness, expand our customer base and store network, and expect to continue to invest heavily in offering discounts and deals and other aspects of our business, especially sales and marketing expenses, in the foreseeable future. In addition, our net revenues will be impacted by various factors, including the performances of our stores, level of discounts we offer, competitive landscape, customer preference and macroeconomic and regulatory environment. Therefore, our revenues may not increase sufficiently to offset the increase in our expenses. We may continue to incur losses in the future and we cannot assure you that we will eventually achieve our intended profitability.

We require a significant amount of capital to fund our operations and respond to business opportunities. If we cannot obtain sufficient capital on acceptable terms, our business, financial condition and prospects may be materially and adversely affected.

        Building a well-known coffee brand and accumulating a large and continuously growing customer base is costly and time-consuming. For example, we require a significant amount of capital to continue to expand our store network in a timely manner. Significant and continuous investments in sales and marketing are also required for further establishing brand awareness among the mass population in China to attract new customers and retain existing ones. In addition, we invest heavily in our technology systems, which are essential to our operations. It may take a long period of time to realize returns on such investments, if at all.

        We have historically funded our cash requirements principally with capital contribution from our shareholders. If these resources are insufficient to satisfy our cash requirements, we may seek to raise funds through additional equity offering or debt financing or obtain additional bank facilities. Our ability to obtain additional capital in the future, however, is subject to a number of uncertainties, including those relating to our future business development, financial condition and results of operations, general market conditions for financing activities by companies in our industry, and macro-economic and other conditions in China and globally. If we cannot obtain sufficient capital on acceptable terms to meet our capital needs, we may not be able to execute our growth strategies, and our business, financial condition and prospects may be materially and adversely affected.

If we are unable to successfully manage our rapid growth, our business and prospects may be materially and adversely affected.

        As we continue to grow rapidly, we will continue to encounter challenges in implementing our managerial, operating and financial strategies to keep up with our growth. The major challenges in managing our business growth include, among other things:

•

controlling incurred costs in a competitive environment;



•

effectively managing our supply chain and ensuring our third-party suppliers continue to meet our quality and other standards and satisfy our future operations' needs;



•

maintaining and upgrading our technology systems in a cost-effective manner;



•

attracting, training and retaining a growing workforce to support our operations;



•

implementing a variety of new and upgraded internal systems and procedures as our business continues to grow; and



•

ensuring full compliance with relevant laws and regulations.

        All efforts to address the challenges of our growth require significant managerial, financial and human resources. We cannot assure you that we will be able to execute managerial, operating and financial strategies to keep up with our growth. If we are not able to manage our growth or execute our strategies effectively, our growth may slow down and our business and prospects may be materially and adversely affected.

If we fail to acquire new customers or retain existing customers in a cost-effective manner, our business, financial condition and results of operations may be materially and adversely affected.

        Our ability to cost-effectively attract new customers and retain existing customers is crucial to driving net revenues growth and achieving profitability. We have invested significantly in branding, sales and marketing to acquire customers since our inception. For example, we offer various discount offers and deals in the form of vouchers and coupons. We also expect to continue to invest significantly to acquire new customers and retain existing ones. There can be no assurance that new customers will stay with us, or the net revenues from new customers we acquire will ultimately exceed the cost of acquiring those customers. In addition, if we reduce or discontinue our current discount offers and deals, if our existing customers no longer find our products appealing, or if our competitors offer more attractive products, prices, discounts or better customer services, our existing customers may lose interest in us, decrease their orders or even stop ordering from us. If we are unable to retain our existing customers or to acquire new customers in a cost-effective manner, our revenues may decrease and our results of operations will be adversely affected.

We may be unsuccessful in operating our stores.

        The operating results of our stores have been and will continue to be subject to a number of factors, including but not limited to:

•

our ability to maintain and enhance the quality of our products and services;



•

our ability to retain existing customers and attract new customers;



•

our ability to timely respond to changes in market opportunities and customer preferences;



•

our ability to maintain good relationships with third-party suppliers, service providers and strategic partners;



•

our ability to hire, train and retain talented employees;



•

our ability to manage costs of our operations, such as cost of materials, store rental and other operating costs, and sales and marketing expenses;



•

our ability to ensure full compliance with relevant laws and regulations, and maintain adequate and effective control, supervision and risk management over our stores; and



•

our ability to monitor and control the overall operation of our stores.

        Many factors that are out of our control, including macroeconomic and regulatory environment, could also adversely affect our store operations. In addition, as we continue to expand our store network, opening new stores near our existing stores may adversely affect the sales of our existing stores. Any of these factors listed above or described elsewhere in this Risk Factors section may render us unsuccessful in profitably operating our stores and could adversely impact our business, financial condition and/or results of operations. We may even have to shut down certain stores if their business, financial conditions and operation results are far below our expectation.

We rely on a limited number of third-party suppliers and service providers to provide products and services to us or to our customers, and the loss of any of these suppliers or service providers would negatively impact our business.

        We have a limited number of suppliers for our raw materials, pre-made food and beverage items, delivery service to our customer and warehouse and fulfillment service. In 2018, we purchased our coffee beans mainly from one supplier, dairy mainly from four suppliers, syrup mainly from three suppliers and pre-made food and beverage items from a few selected national, regional and local sources. We also mainly rely on one delivery service provider to provide delivery service to our customers and cooperate with three warehouse and fulfillment service providers for our inventory storage, and fulfilments between warehouses and from warehouses to our stores.

        Due to concentration of suppliers, any interruption of the operations of our suppliers, any failure of our suppliers to accommodate our fast growing business scale, any termination or suspension of our supply arrangements, any change in cooperation terms, or the deterioration of cooperative relationships with these suppliers may materially and adversely affect our results of operations. In addition, our current agreements with our suppliers generally do not prohibit them from working with our competitors. Our competitors may be more effective in providing incentives to our suppliers to prioritize on their orders in case of short supply. We cannot assure you that we would be able to find replacement suppliers on commercially reasonable terms or a timely basis.

Failure to maintain the quality and safety of our products could have a material and adverse effect on our reputation, financial condition and results of operations.

        The quality and safety of our products are critical to our success. We pay close attention to quality control, monitoring each step in the process from procurement to production and from warehouse to delivery. For more information on our quality control system, see "Business—Procurement" and

Table of Contents

"Business—Quality Control." Yet, due to the scale of our operations and rapid growth of our store network, maintaining consistent product quality depends significantly on the effectiveness of our quality control system, which in turn depends on a number of factors, including but not limited to the design of our quality control system, employee training to ensure that our employees adhere to and implement our quality control policies and procedures and the effectiveness of monitoring any potential violation of our quality control policies and procedures. There can be no assurance that our quality control system will always prove to be effective.

        In addition, the quality of the products or services provided by our suppliers or service providers is subject to factors beyond our control, including the effectiveness and the efficiency of their quality control system, among others. There can be no assurance that our suppliers or service providers may always be able to adopt appropriate quality control systems and meet our stringent quality control requirements in respect of the products or services they provide. Any failure of our suppliers or service providers to provide satisfactory products or services could harm our reputation and adversely impact our operations. See "—Illegal actions or misconduct, or any failure by third-party suppliers or service providers to provide satisfactory products or services could materially and adversely affect our business, reputation, financial condition and results of operations. In addition, we may be unable to receive sufficient compensation from suppliers and service providers for the losses caused by them."

        If customers become ill from food or beverage-borne illnesses, tampering, adulteration, contamination, mislabeling or other food or beverage-safety issues, we could be forced to temporarily close some stores and/or be involved in related disputes or legal proceedings. In addition, instances of food or beverage-safety issues, even those not involving us or our suppliers, could, by resulting in negative publicity about us, China's coffee industry or China's food and beverage market in general, adversely affect our reputation, financial condition and results of operations. A decrease in customer confidence in the safety and quality of our products or any food safety issues could materially harm our business and results of operations. See "—Adverse incidents or reports of food-safety issues, whether true or not, may harm our business."

Any significant disruption in our technology infrastructure or our failure to maintain the satisfactory performance, security and integrity of our technology infrastructure would materially and adversely affect our business, reputation, financial condition and results of operations.

        The proper functioning of our technology infrastructure is essential to our business. We rely on our technology to improve customer engagement and our operational efficiency, among others. See "Business—Technology." The risks we face in relation to the disruption of our technology infrastructure include:

•

we may encounter problems when upgrading our technology infrastructure including our mobile apps, systems and software. The development, upgrades and implementation of our technology infrastructure are complex processes. Issues not identified during pre-launch testing of new services may only become evident when such services are made available to our entire customer base. Therefore, our technology infrastructure, including our mobile apps, may not function properly if we fail to detect or solve technical errors in a timely manner; and



•

our systems are potentially vulnerable to damage or interruption as a result of earthquakes, floods, fires, extreme temperatures, power loss, telecommunications failures, technical error, computer viruses, hacking and similar events.

        These and other events may lead to the unavailability of our mobile apps, interruption of our supply chain and delivery, leakage or permanent loss of customer data, interruptions or decreases in connection speed, or other events which would affect our operations. If we experience frequent or persistent service disruptions, whether caused by failures of our own systems or those of third-party suppliers or service providers, our reputation or relationships with our customers may be damaged and

our customers may switch to our competitors, which may have a material adverse effect on our business, financial condition and results of operations.

We face intense competition in China's coffee industry and our products are not proprietary. If we fail to compete effectively, we may lose market share and customers, and our business, financial condition and results of operations may be materially and adversely affected.

        China's coffee industry is intensely competitive. Our products, including our coffee recipes, are not proprietary, and therefore, we are unable to prevent competitors from copying the recipes of our products and sell similar products. We mainly compete with a number of coffee shop operators for customers. Our competitors may have more financial, technical, marketing and other resources than we do and may be more experienced and able to devote greater resources to the development, promotion and support of their business. Some competitors are well-established in China and any defensive measures they take in response to our expansion could hinder our growth and adversely affect our sales and results of operations. In addition, China's coffee industry is subject to the entry of new and well-funded competitors. For more information related to the competitive landscape of China's coffee industry, see "Business—Competition."

        Increased competition may reduce our market share and profitability and require us to increase our sales and marketing efforts and capital commitment in the future, which could negatively affect our results of operations or force us to incur further losses. Although we have accumulated a large and continuously growing customer base, there is no assurance that we will be able to continue to do so in the future against current or future competitors, and such competitive pressures may have a material adverse effect on our business, financial condition and results of operations.

Our business is currently highly dependent on coffee and we may not be able to quickly identify new market opportunities, respond to the industry trends and adapt to customer preferences.

        The growth of China's coffee industry is affected by customer taste, preferences, perceptions and spending patterns. Since we have generated, and expect to continue to generate a considerable amount of our revenues from the sale of coffee, a shift in customer preferences away from coffee, the changes of spending pattern adversely affecting consumption of coffee, or the decrease or slow-growth of coffee consumption in China would harm our business, more than if our revenues were generated from more diversified products.

        We have devoted significant resources to launch and promote new products from time to time to serve broader customer demand, adapt to changes in market trends and shifts in customer taste and preferences, including the introduction of new coffee flavors and non-coffee products. However, we may not be successful in implementing our cross-selling strategy, developing innovative new products, and our new products may not be favored by customers or commercially successful. To the extent that we are not able to effectively gauge the direction of our key markets and successfully identify, develop and promote new or improved products in the changing market, our financial results and our competitive position will suffer.

Growth of our business will partially depend on the recognition of our brand, and any failure to maintain, protect and enhance our brand would limit our ability to expand or retain our customer base, which would materially and adversely affect our business, financial condition and results of operations.

        We believe that recognition of our brand among customers has helped us manage our customer acquisition costs and contributed to the growth and success of our business. Accordingly, maintaining, protecting and enhancing the recognition of our brand is critical to our business and market position. Many factors, some of which are beyond our control, are important to maintaining, protecting and enhancing our brand. These factors include but not limited to our ability to:

•

maintain the quality and attractiveness of the products we offer;

18

---

Table of Contents

•

develop and launch new products that satisfy our customers' needs;



•

provide a superior customer experience;



•

increase brand awareness through marketing and brand promotion activities;



•

maintain good relationship and retain favorable terms with our suppliers, service providers and other business partners;



•

stay compliant with relevant laws and regulations;



•

compete effectively against existing and future competitors; and



•

preserve our reputation and goodwill generally and in the event of any negative publicity on our products, services and data security, or other issues affecting us, China's coffee industry or China's food and beverage sector in general.

        A public perception that we, or other industry participants do not provide satisfactory products or services to customers, even if factually incorrect or based on isolated incidents, could damage our reputation, diminish the value of our brand, undermine the trust and credibility we have established and have a negative impact on our ability to attract and retain customers, and our business, financial condition and results of operations may be materially and adversely affected.

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

        Publicity about our business creates the possibility of heightened attention from the public, regulators and the media. Heightened regulatory and public concerns over customer protection and customer safety issues may subject us to additional legal and social responsibilities and increased scrutiny and negative publicity over these issues, due to our large number of transactions and continued business expansion. Any negative report regarding our business, financial condition and results of operations could damage our brand image and severely affect the sales of our products and possibly lead to product liability claims, litigations or damages. In addition, improper behaviors or statements of our spokespersons, endorsers and other celebrities we have cooperated with and our employees may result in substantial harm to our brand, reputation and operations. There is no assurance that we would not become a target for regulatory or public scrutiny in the future or that scrutiny and public exposure would not severely damage our reputation as well as our business and prospects.

We have incurred significant costs on a variety of sales and marketing efforts, including mass advertising and heavy promotions to attract customers, and some sales and marketing campaigns and methods may not be sustainable or may turn out to be ineffective.

        We have invested significantly in sales and marketing activities to promote our brand and our products and to deepen our relationships with customers. We incurred RMB25.5 million and RMB746.0 million (US$108.5 million) in sales and marketing expenses for the period from June 16, 2017 (inception date) to December 31, 2017 and the year ended December 31, 2018. We also regularly offer coupons and vouchers to increase our customer base, retain our existing customers or promote new products, and such promotion activities might not be sustainable.

        Our sales and marketing activities may not be well received by our existing customers, and may not attract new customers as anticipated. The evolving marketing landscape may require us to experiment with new marketing methods to keep pace with industry trends and customer preferences. Failure to refine our existing marketing approaches or to introduce new marketing approaches in a cost-effective manner could reduce our market share and negatively impact our results of operations. There is no assurance that we will be able to recover the costs of our sales and marketing activities or that these activities will be effective in attracting new customers and retaining existing customers.

Table of Contents

We may be unsuccessful in expanding our store network.

        We may not be able to expand our store network as we planned. The number and timing of the stores actually opened during any given period are subject to a number of risks and uncertainties, including but not limited to our ability to:

•

identify suitable locations and secure leases on commercially reasonable terms;



•

obtain adequate funding for development and opening costs;



•

obtain the required licenses, permits and approvals;



•

efficiently manage our time and cost in relation to the design, decoration and pre-opening processes for each of our stores; and



•

hire, train and retain skilled employees.

        Any factors listed above, either individually or in aggregate, might delay or fail our plan to increase the number of stores in desirable locations at manageable cost levels. In addition, we may not be able to successfully operate our existing stores and may choose to shut down certain stores from time to time.

Any lack of requisite approvals, licenses or permits applicable to our business may have a material and adverse impact on our business, financial condition and results of operations.

        In accordance with the relevant laws and regulations in jurisdictions in which we operate, we are required to maintain various approvals, licenses and permits to operate our business, including but not limited to business license, food operation license, environmental impact assessment filing and fire safety inspection. These approvals, licenses and permits are obtained upon satisfactory compliance with, among other things, the applicable laws and regulations.

        As of the date of this prospectus, a small portion of our stores have not obtained business licenses. We are in the process of obtaining business licenses for these stores; however, we may be ordered by the government authorities to rectify such non-compliance and may be subject to fines of up to RMB100,000 for each store that failed to obtain business licenses.

        As of the date of this prospectus, a small portion of our stores have not obtained food operation licenses. We are in the process of obtaining food operation licenses for these stores; however, the relevant government authorities may confiscate the income of these stores since commencing operation as well as the food and beverage products sold at these stores and the raw materials and equipment used in store operation, and may impose fines based on the value of the food and beverage products sold at each store (if the value of the food and beverage products is less than RMB10,000, a fine up to RMB100,000 may be imposed, if the value of the food and beverage products is more than RMB10,000, a fine up to 20 times of such value may be imposed).

        As of the date of this prospectus, a small portion of our stores that are required to complete environmental impact assessment filings with the administrative department of environmental protection have not completed such filings. We are in the process of completing such filing for these stores, however, if we fail to complete such filing in a timely manner, we may be subject to a fine of up to RMB50,000 per store.

        Based on consultation with local fire prevention authorities by our PRC legal counsel, the requirements of conducting fire safety inspection for coffee stores before their commencement of operations varies among cities. In Tianjin and Wuhan, only coffee stores with construction area of more than 500 square meters are required to conduct fire safety inspection before use, therefore, our stores in these cities are not required to conduct the fire safety inspection; In Beijing, Guangzhou, Fuzhou, Chengdu, Xiamen, Ningbo, Jinan and Zhengzhou, coffee stores with construction area of more than 300 square meters are required to conduct the fire safety inspection before use, and some of our stores

in these cities that are required to complete such inspection have not completed such inspection; In Hangzhou, coffee stores with construction area of more than 200 square meters are required to conduct fire safety inspection before use, and some of our stores in these cities that are required to complete such inspection have not completed such inspection; in Shenzhen and Dongguan, coffee stores with construction area of more than 50 square meters are required to conduct fire safety inspection before use, and some of our stores in these cities that are required to complete such inspection have not completed such inspection; in other cities where we operate, such as Shanghai, Wuxi, Changsha, Chongqing, Qingdao, Xi'an, Suzhou, Dalian and Nanjing, coffee stores are required to conduct fire safety inspection before use regardless of size, and some of our stores in these cities have not completed such inspection. As of the date of this prospectus, approximately one-third of our stores have not completed the fire safety inspection. Our stores that fail to complete fire safety inspections may be ordered by the relevant government authorities to close down and may be subject to a fine of up to RMB300,000 per store.

        In addition, a small number of our stores with construction area of more than 500 or 300 square meters have not completed the as-built acceptance check on fire prevention or fire safety filing. Our stores that fail to complete such as-built acceptance check on fire prevention may be ordered by the relevant government authorities to close down and may be subject to a fine of up to RMB300,000 per store, and our stores that fail to compete such fire safety filing may be subject to a fine of up to RMB5,000 per store.

        As of the date of this prospectus, we are in the process of completing the single-purpose commercial prepaid card filing for the "Coffee Wallet" function of our mobile apps. We may be imposed a fine of up to RMB30,000 for failure to timely completing such filing.

        If we fail to obtain the necessary licenses, permits and approvals, we may be subject to fines, confiscation of the gains derived from the related stores or the suspension of operations of the related stores. We may also experience adverse publicity arising from such non-compliance with government regulations that negatively impact our brand. We may experience difficulties or failures in obtaining the necessary approvals, licenses and permits for new stores. If we fail to obtain the material licenses, our store opening and expansion plan may be delayed. In addition, there can be no assurance that we will be able to obtain, renew and/or convert all of the approvals, licenses and permits required for our existing business operations upon their expiration in a timely manner or at all, which could adversely affect our business operations.

We have recorded negative cash flows from operating activities historically and may have a current liabilities position in the future.

        We have experienced significant cash outflow from operating activities since our inception. We had net cash used in operating activities of RMB95.0 million and RMB1,310.7 million (US$190.6 million) for the period from June 16, 2017 (inception date) to December 31, 2017 and the year ended December 31, 2018, respectively. The cost of continuing operations could further reduce our cash position, and an increase in our net cash outflow from operating activities could adversely affect our operations by reducing the amount of cash available to meet the cash needs for operating our business and to fund our investments in our business expansion.

        We had net current liabilities of RMB129.2 million as of December 31, 2017. Although we had net current assets of RMB1,647.8 million (US$239.7 million) as of December 31, 2018, we cannot guarantee that we will not have a net current liabilities position in the future, which would expose us to liquidity risk. Our future liquidity and ability to make additional capital investments necessary for our operations and business expansion will depend primarily on our ability to maintain sufficient cash generated from operating activities and to obtain adequate external financing. There can be no assurance that we will be able to renew existing bank facilities or obtain other sources of financing.

Failure to comply with the terms of our indebtedness could result in acceleration of indebtedness, which could have an adverse effect on our cash flow and liquidity.

        We may from time to time enter into credit facilities and debt financing arrangements containing financial and other covenants that could, among other things, restrict our business and operations. If we breach any of these covenants, including by failing to maintain certain financial ratios, our lenders may be entitled to accelerate our debt obligations. Any default under our credit facility could require that we repay these loans prior to maturity as well as limit our ability to obtain additional financing, which in turn may have a material adverse effect on our cash flow and liquidity.

From time to time we may evaluate and potentially consummate strategic investments or acquisitions, which may turn out to be not successful and adversely affect our operation and financial results.

        To complement our business and strengthen our market-leading position, we may form strategic alliances or make strategic investments and acquisitions from time to time. For example, we incorporated a joint venture in May 2018 with one of our roasted coffee bean suppliers for solidifying our control over the processes of sourcing and roasting coffee beans and as of the date of the prospectus, the joint venture has not started operation. We may experience difficulties in integrating our operations with the newly invested or acquired businesses, implementing our strategies or achieving expected levels of net revenues, profitability, productivity or other benefits. Therefore, we cannot assure you that our investments or acquisitions will benefit our business strategy, generate sufficient net revenues to offset the associated investment or acquisition costs, or otherwise result in the intended benefits.

We have undertaken strategic partnerships which may not be successful. If our collaboration with any of our strategic partners is terminated or curtailed, or if we are no longer able to benefit from the business collaborations with our strategic partners, our business may be adversely affected.

        Our business has benefited from our collaborations with our strategic partners, including Weixin, in the areas such as mobile ordering and payment and joint marketing. We cannot assure you that such alliances or partnerships will contribute to our business, and we might not be able to maintain our cooperative relationships with our strategic partners and their respective affiliates in the future. If the services provided by these strategic partners become limited, compromised, restricted, curtailed or less effective or become more expensive or unavailable to us for any reason, our business may be materially and adversely affected. To the extent we cannot maintain our cooperative relationships with any of these strategic partners, it may be very difficult for us to identify other alternative partners, which may divert significant management attention from existing business operations and adversely impact our daily operation and customer experience.

A significant interruption in the operations of our third-party suppliers and service providers could potentially disrupt our operations.

        We have limited control over the operations of our third-party suppliers, service providers and other business partners and any significant interruption in their operations may have an adverse impact on our operations. For example, a significant interruption in the operations of our roasted coffee bean suppliers' roasting facilities could cause a shortage of coffee at our stores, a significant interruption impacting our leased warehouses, whether as a result of a natural disaster, labor difficulties, fire or other causes, could cause the shortage of our inventory, and a significant interruption in the operations of our internet service provider could impact the operation of our mobile apps. If we could not solve the impact of the interruptions of operations of our third-party suppliers or service providers, our business operations and financial results may be materially and adversely affected.

Illegal actions or misconduct, or any failure by third-party suppliers or service providers to provide satisfactory products or services could materially and adversely affect our business, reputation, financial condition and results of operations. In addition, we may be unable to receive sufficient compensation from suppliers and service providers for the losses caused by them.

        Our reputation and operation may be harmed by illegal or unsatisfactory actions taken by suppliers and service providers that are outside of our control. For example, the failure of our raw material suppliers to ensure product quality or to comply with food safety or other laws and regulations could interrupt our operations and result in claims against us, and any delay in delivery of our products, damage to our products during the course of delivery and inappropriate actions taken by delivery riders of our delivery service providers might cause customer complaints.

        In the event that we become subject to claims caused by actions taken by our suppliers or service providers, we may attempt to seek compensation from the relevant suppliers or service providers. However, such compensation may be limited. If no claim can be asserted against a supplier or service provider, or amounts that we claim cannot be fully recovered from the supplier or service provider, we may be required to bear such losses and compensation at our own costs. This could have a material and adverse effect on our business, financial condition and results of operations.

We face the risk of fluctuations in the cost, availability and quality of our raw materials and pre-made products, which could adversely affect our results of operations.

        The cost, availability and quality of our principal raw material, Arabica coffee beans, coffee condiments, such as dairy products and syrup, as well as pre-made food and beverage items, are important to our operations. We typically enter into purchase agreements with suppliers of raw materials and pre-made food and beverage items with a term of one year and fixed prices. However, such contract prices may be renegotiated when there is significant fluctuation in the market price of these products. If the cost of raw materials and pre-made products increases after expiration of existing agreements, due to large market price fluctuation or due to any other reason, our business and results of operations could be adversely affected. In addition, as coffee beans and most of our coffee condiments and pre-made products have relatively short shelf life, frequent and timely supply of these products are essential to our operations. Lack of availability of these products, whether due to shortages in supply, delays or interruptions in processing, failure of timely delivery or otherwise, could interrupt our operations and adversely affect our financial results.

Uncertainties relating to the growth of China's coffee industry could adversely affect our revenues and business prospects.

        Our business is affected by the development of China's coffee industry. The demand for our coffee items and our future results of operations will depend on numerous factors affecting the development of the China's coffee industry, such as governmental regulations and policies over this industry, investments in this industry and drinking culture and hobby of Chinese consumers, and some of them are completely beyond our control.

        A decline in the popularity of coffee in general, especially freshly brewed coffee, or any failure by us to adapt our strategies in response to trends in China's coffee industry, may adversely affect our results of operations and business prospects.

Adverse public or medical opinion about the health effects of our products may harm our business.

        Some of our products contain caffeine, dairy products, sugar and other active compounds, the health effects of which are not fully understood. The excessive consumption of these compounds may result in adverse health effects and have caused increasing public awareness. For example, a number of research studies conclude or suggest that excessive consumption of caffeine may lead to increased heart

rate, nausea and vomiting, restlessness and anxiety, depression, headaches, tremors, sleeplessness and other adverse health effects. Unfavorable reports on the health effects of caffeine or other compounds of our products could significantly reduce the sales of our products. Also, we could become subject to litigation relating to the existence of such compounds in our products; any such litigation could be costly and could divert management attention.

Adverse incidents or reports of food-safety issues, whether true or not, may harm our business.

        Instances or reports of food-safety issues, such as food or beverage-borne illnesses, tampering, adulteration, contamination or mislabeling, either during growing, manufacturing, packaging, storing or preparation, whether true or not, have in the past severely injured the reputations of companies in China's food and beverage market and could affect us as well. Product safety or quality issues, actual or perceived, or allegations of product contamination, even when false or unfounded, could tarnish the image of our brand and may cause customers to choose other products. Such issues could negatively affect our reputation, results of operations and financial performance.

Our success depends on the continuing efforts of our key management and experienced and capable personnel as well as our ability to recruit new talents. If we fail to hire, train, retain or motivate our staff, our business may suffer.

        Our future success is significantly dependent upon the continued service of our key management as well as experienced and capable personnel generally. If we lose the services of any member of key management, 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. If any of our key management joins a competitor or forms a competing business, we may lose customers, know-how and key professionals and staff members.

        Our rapid growth also requires us to hire, train, and retain a wide range of talents who can adapt to a dynamic, competitive and challenging business environment and are capable of helping us conduct effective marketing, innovate new products, and develop technological capabilities. We will need to continue to attract, train and retain talents at all levels, such as skillful baristas, as we expand our business and operations. We may need to offer attractive compensation and other benefits package, including share-based compensation, to attract and retain them. We also need to provide our employees with sufficient training to help them to realize their career development and grow with us. Any failure to attract, train, retain or motivate key management and experienced and capable personnel could severely disrupt our business and growth.

Overall tightening of the labor market, increases in labor costs or any possible labor unrest may adversely affect our business and results of operations.

        Our business requires a substantial number of personnel. Any failure to retain stable and dedicated labor by us may lead to disruption to our business operations. Although we have not experienced any labor shortage to date, we have observed an overall tightening and increasingly competitive labor market. We have experienced, and expect to continue to experience, increases in labor costs due to increases in salary, social benefits and employee headcount. We compete with other companies in our industry and other labor-intensive industries for labor, and we may not be able to offer competitive remuneration and benefits compared to them. If we are unable to manage and control our labor costs, our business, financial condition and results of operations may be materially and adversely affected.

Our business generates and processes a large amount of data, which subjects us to governmental regulations and other legal obligations related to privacy, information security and data protection. Any improper use or disclosure of such data by us, our employees or our business partners could subject us to significant reputational, financial, legal and operational consequences.

        Our business generates and processes a large quantity of personal, transaction, and behavior data. We face risks inherent in handling large volumes of data and in protecting the security of such data. In particular, we face a number of challenges relating to data from transactions and other activities on our system, including:

•

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



•

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



•

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

        Any systems failure or security breach or lapse that results in the release of customer data could harm our reputation and brand and, consequently, our business, in addition to exposing us to potential legal liability. In addition, our business partners and their employees may improperly use or disclose the data we disclose to them for our operation and we have limited control over the actions of our business partners and their employees. Any failure, or perceived failure, by us, our employees, our business partners, or their employees to comply with 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, require us to change our business practices, increase our costs and severely disrupt our business.

        Recently, companies' practices regarding collection, use, retention, transfer, disclosure and security of user data have been the subject of enhanced regulations and increased public scrutiny. The regulatory frameworks regarding privacy issues in many jurisdictions are constantly evolving and can be subject to significant changes from time to time. For instance, a growing number of legislative and regulatory bodies have adopted customer notification requirements in the event of unauthorized access to or acquisition of certain types of data. In China, the PRC Cybersecurity Law, which became effective in June 2017, leaves substantial uncertainty as to the circumstances and standards under which the law would apply and violations would be found. See "Regulation—Regulation on Information Security" and "Regulation—Regulation on Internet Privacy." Complying with these obligations could cause us to incur substantial costs. Any failure to comply with applicable regulations, whether by us, business partners, or other third parties, or as a result of employee error or negligence or otherwise, could result in regulatory enforcement actions against us and have an adverse impact on our business operations.

If we fail to adopt new technologies to evolving customer needs or emerging industry standards, our business may be materially and adversely affected.

        To remain competitive, we must continue to stay abreast of the constantly evolving industry trends and to enhance and improve our technology accordingly. Our success will depend, in part, on our ability to identify, develop, acquire or license leading technologies useful in our business. There can be no assurance that we will be able to use new technologies effectively or adapt our mobile apps to meet customer requirements. If we are unable to adapt in a cost-effective and timely manner in response to changing market conditions or customer preferences, whether for technical, legal, financial or other reasons, our business may be materially and adversely affected.

Security breaches and attacks against our technology systems, and any potentially resulting breach or failure to otherwise protect confidential and proprietary information, could damage our reputation and negatively impact our business, as well as materially and adversely affect our financial condition and results of operations.

        Although we have employed significant resources to develop our security measures against breaches, our cybersecurity measures may not detect or prevent all attempts to compromise our systems, including distributed denial-of-service attacks, viruses, malicious software, break-ins, phishing attacks, social engineering, security breaches or other attacks and similar disruptions that may jeopardize the security of information stored in and transmitted by our systems or that we otherwise maintain. Breaches of our cybersecurity measures could result in unauthorized access to our systems, misappropriation of information or data, deletion or modification of customer information, or a denial of service or other interruption to our business operations. As techniques used to obtain unauthorized access to or sabotage systems change frequently and may not be known until launched against us or our third-party service providers, we may be unable to anticipate, or implement adequate measures to protect against, these attacks.

        We have in the past and are likely again in the future to be subject to these types of attacks, although to date no such attack has resulted in any material damages or remediation costs. If we are unable to avert these attacks and security breaches, we could be subject to significant legal and financial liability, our reputation would be harmed and we could sustain substantial lost sales and customer dissatisfaction. We may not have the resources or technical sophistication to anticipate or prevent rapidly evolving types of cyber-attacks. Actual or anticipated attacks and risks may cause us to incur significantly higher costs, including costs to deploy additional personnel and network protection technologies, train employees and engage third-party experts and consultants.

The payment methods that we accept subject us to third-party payment-related risks and other risks.

        We accept a variety of payment methods including Weixin Pay, Alipay and Union Pay through third-party payment processors. We pay these payment processors varying service fees, which may increase over time and raise our operating costs. We may also be subject to fraud, security breaches and other illegal activities in connection with the various payment methods we offer.

        In addition, we are subject to various rules, regulations and requirements, regulatory or otherwise, governing payment processing, which could change or be reinterpreted to make it difficult or impossible for us to comply. For example, according to Announcement No.10 (2018) of the People's Bank of China issued in July 2018, or Announcement No.10, companies that refuse to accept cash payment should rectify such non-compliance. According to People's Bank of China's interpretation of Announcement No.10, e-commence platforms, self-service counters and other companies (i) that offer products and services online and in a cashier-less manner, (ii) whose entire customer purchase process does not involve payment or receipt of cash, and (iii) who have obtained consent from customers to use electronic payment methods, may use electronic payment methods instead of accepting cash. We believe that our cashier-less operation is in compliance with Announcement No. 10, and our PRC legal counsel has advised us the likelihood that we would be subject to penalties under Announcement No.10 is remote. However, we cannot assure you that the relevant governmental authorities will have the same interpretation. If we fail to comply with these rules or requirements, we may be subject to fines and higher transaction fees or no longer be able to offer certain payment methods, and our business, financial condition and results of operations could be materially and adversely affected.

We use software licensed from third parties. Our ability to provide customers with a high-quality online experience also depends on the satisfactory performance, reliability and availability of software licensed from third parties.

        We use software licensed from third parties. Any system interruptions caused by telecommunications failures, computer viruses, or hacking or other attempts to harm the software licensed from third parties that result in the unavailability of our mobile apps or reduced performance would affect the attractiveness of the services offered on our platform. We may encounter problems when software licensed from third parties is upgraded and undetected programming errors could adversely affect the performance of the software we use to provide our services. In addition, we could be required to seek licenses from third parties in order to continue using the open source software we are permitted to use currently, in which case licenses may not be available on terms that are acceptable to us, or at all. Alternatively, we may need to re-engineer our platform or discontinue the use of portions of the functionality provided by our platforms. Our inability to use third-party software could result in disruptions to our business, or delays in the development of future offerings or enhancements of our existing platforms, which could materially and adversely affect our business and results of operations.

Unexpected termination of leases, failure to renew the lease of our existing premises or to renew such leases at acceptable terms could materially and adversely affect our business.

        We lease the premises for all of our stores. Generally, lessors may terminate our lease agreements unilaterally upon advance notice. In addition, the PRC government has the statutory power to acquire any land in the PRC. As a result, we may be subject to compulsory acquisition, closure or demolition of any of the properties on which our stores are situated. Although we may receive liquidated damages or compensation if our leases are terminated unexpectedly, we may be forced to suspend operations of the relevant store and divert management attention, time and costs to find a new site and relocate our store, which will negatively affect our business and results of operations.

        We generally enter into long-term leases of approximately three to five years with an option to renew for our stores. Rent for our leases is typically fixed amounts and subject to annual or biennially incremental increases as stipulated in the lease agreements. We cannot assure you that we would be able to renew the relevant lease agreements without substantial additional cost or increase in the rental cost payable by us. If a lease agreement is renewed at a rent substantially higher than the current rate, or currently existing favorable terms granted by the lessor are not extended, our business and results of operations may be materially and adversely affected. If we are unable to renew the leases for our store sites, we will have to close or relocate the store, which could subject us to decoration and other costs and risks, and loss of existing customers, and could have a material and adverse effect on our business and results of operations. In addition, the relocated store may not perform as well as the existing store.

Most of the lease agreements of our leased properties have not been registered with the relevant PRC government authorities as required by PRC law, which may expose us to potential fines.

        Under PRC law, all lease agreements are required to be registered with the local land and real estate administration bureau. Although failure to do so does not in itself invalidate the leases, the lessees may not be able to defend these leases against bona fide third parties and may also be exposed to potential fines if they fail to rectify such non-compliance within the prescribed time frame after receiving notice from the relevant PRC government authorities. The penalty ranges from RMB1,000 to RMB10,000 for each unregistered lease, at the discretion of the relevant authority. As of the date of this prospectus, the lease agreements for most of our leased properties in China, including leased properties for our stores, have not been registered with the relevant PRC government authorities. In the event that any fine is imposed on us for our failure to register our lease agreements, we may not be able to recover such losses from the lessors.

Our rights to use our leased properties could be challenged by property owners or other third parties, which may disrupt our operations and incur relocation costs.

        As of the date of this prospectus, the lessors of certain of our leased properties in China failed to provide us with valid property ownership certificates or authorizations from the property owners for the lessors to sublease the properties. There is a risk that such lessors may not have the relevant property ownership certificates or the right to lease or sublease such properties to us, in which case the relevant lease agreements may be deemed invalid and we may be forced to vacate these properties, which could interrupt our business operations and incur relocation costs. Moreover, if our lease agreements are challenged by third parties, it could result in diversion of management attention and cause us to incur costs associated with defending such actions, even if such challenges are ultimately determined in our favor.

We may experience significant liability claims or complaints from customers, or adverse publicity involving our products, our services or our stores.

        We face an inherent risk of liability claims or complaints from our customers. Most of the customer complaints we received were related to the taste and temperature of our food and beverage offerings, long waiting time, and the service quality of our staff. We take these complaints seriously and endeavor to reduce such complaints by implementing various remedial measures. Nevertheless, we cannot assure you that we can successfully prevent or address all customer complaints.

        Any complaints or claims against us, even if meritless and unsuccessful, may divert management attention and other resources from our business and adversely affect our business and operations. Customers may lose confidence in us and our brand, which may adversely affect our business and results of operations. Furthermore, negative publicity including but not limited to negative online reviews on social media and crowd-sourced review platforms, industry findings or media reports related to food quality, safety, public health concerns, illness, injury or government, whether or not accurate, and whether or not concerning our products, can adversely affect our business, results of operations and reputation.

We, our directors, management and employees may be subject to litigation and regulatory investigations and proceedings, such as claiming in relation to food safety, commercial, labor, employment, antitrust or securities matters, and may not always be successful in defending ourselves against such claims or proceedings.

        We face potential liability, expenses for legal claims and harm due to our business nature. For example, customers could assert legal claims against us in connection with personal injuries related to food poisoning or tampering. The PRC government, media outlets and public advocacy groups have been increasingly focused on customer protection in recent years. See "Regulation—Regulations Relating to Customer Rights Protection." Selling of defective products may expose us to liabilities associated with customer protection laws. Sellers are responsible for compensation on customer's loss even if the contamination of food is not caused by the sellers. Thus, we may also be held liable if our suppliers or other business partners fail to comply with applicable food-safety related rules and regulations. Though we can ask the responsible parties for indemnity after that, our reputation could still be adversely affected. In addition, our directors, management and employees may from time to time be subject to litigation and regulatory investigations and proceedings or otherwise face potential liability and expense in relation to commercial, labor, employment, antitrust, securities or other matters, which could adversely affect our reputation and results of operations.

        After we become a publicly listed company, we may face additional exposure to claims and lawsuits. These claims could divert management time and attention away from our business and result in significant costs to investigate and defend, regardless of the merits of the claims. In some instances,

28

we may elect or be forced to pay substantial damages if we are unsuccessful in our efforts to defend against these claims, which could harm our business, financial condition and results of operations.

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

        We cannot be certain that our operations or any aspects of our business do not or will not infringe upon or otherwise violate intellectual property rights held by third parties. We have not but in the future may be, subject to legal proceedings and claims relating to the intellectual property rights of others. There could also be existing intellectual property of which we are not aware that our products may inadvertently infringe. We cannot assure you that holders of intellectual property purportedly relating to some aspect of our technology platform or business, if any such holders exist, would not seek to enforce such intellectual property against us in China, the United States or any other jurisdictions. If we are found to have violated the intellectual property rights of others, we may be subject to liability for our infringement activities or may be prohibited from using such intellectual property, and we may incur licensing fees or be forced to develop alternatives of our own. In addition, we may incur significant expenses, and may be forced to divert management's time and other resources from our business and operations to defend against these infringement claims, regardless of their merits. Successful infringement or licensing claims made against us may result in significant monetary liabilities and may materially disrupt our business and operations by restricting or prohibiting our use of the intellectual property in question, and our business, financial position and results of operations could be materially and adversely affected.

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

        We regard our trademarks, software copyrights, copyright of works, domain names, know-how, proprietary technologies, and similar intellectual property as critical to our success. There have been instances where third parties registered social media accounts under names similar to our trademarks in order to gain illegal benefits, against which we have initiated legal proceedings, and we may continue to become an attractive target to such attacks in the future with the increasing recognition of our brand. Any of our intellectual property rights could be challenged, invalidated, circumvented or misappropriated, or such intellectual property may not be sufficient to provide us with competitive advantages. In addition, there can be no assurance that (i) our pending applications for intellectual property rights will be approved, (ii) all of our intellectual property rights will be adequately protected, or (iii) our intellectual property rights will not be challenged by third parties or found by a judicial authority to be invalid or unenforceable.

We are subject to regulations, and future regulations may impose additional requirements and obligations on our business or otherwise materially and adversely affect our business, reputation, financial condition and results of operations.

        The industries in which we operate are highly regulated. As China's coffee industry as well as China's food and beverage market in general is evolving rapidly and the PRC government is very concerned about customer protection, new laws and regulations may be adapted to address new issues that arise from time to time and to impose additional restrictions on our current business.

        As we continue to grow in scale and significance, we expect to face increased scrutiny, which will, at a minimum, result in our having to increase our investment in compliance and related capabilities and systems. The increasing sophistication and development of our customer base will also increase the need for higher standards of customer protection, privacy protection and dispute management. Any increased involvement in inquiries or investigations could result in significantly higher legal and other costs and diversion of management and other resources, as well as negative publicity, which could materially and adversely affect our business, reputation, financial condition and results of operations.

Our operations depend on the performance of the mobile based systems, telecommunications networks and digital infrastructure in China.

        Our new retail business model relies heavily on mobile based systems, telecommunications networks and digital infrastructure. Almost all access to the internet in China is maintained through state-owned telecommunication operators under the administrative control and regulatory supervision of the Ministry of Industry and Information Technology. Moreover, we primarily rely on a limited number of telecommunication service providers to provide us with data communications capacity through local telecommunications lines and internet data centers to host our servers. We have limited access to alternative networks or services in the event of disruptions, failures or other problems with China's internet infrastructure or the fixed telecommunications networks provided by telecommunication service providers. With the expansion of our business, we may be required to upgrade our technology and infrastructure to keep up with the increasing traffic on our mobile apps. We cannot assure you that the digital infrastructure and the telecommunications networks in China will be able to support the demands associated with the continued growth in digital usage.

        In addition, we have no control over the costs of the services provided by telecommunication service providers. If the prices we pay for telecommunications and digital services rise significantly, our results of operations may be materially and adversely affected. Furthermore, if data access fees or other charges to mobile users increase, our user traffic may decline and our business may be harmed.

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

        Prior to this offering, we have been a private company with limited accounting and financial reporting personnel and other resources with which we address our internal control over financial reporting. In connection with the audit of our consolidated financial statements as of and for the year ended December 31, 2018, we and our independent registered public accounting firm identified two material weaknesses in our internal control over financial reporting. As defined in the standards established by the U.S. Public Company Accounting Oversight Board, or PCAOB, a "material weakness" is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements will not be prevented or detected on a timely basis.

        The material weaknesses identified are our company's lack of sufficient accounting and financial reporting personnel with requisite knowledge and experience in application of U.S. GAAP and the Securities and Exchange Commission, or the SEC, rules, and lack of financial reporting policies and procedures that are commensurate with U.S. GAAP and the SEC reporting requirements. We are in the process of implementing a number of measures to address the material weaknesses and deficiencies that have been identified. See "Management's Discussion and Analysis of Financial Condition and Results of Operations—Internal Control Over Financial Reporting." However, we cannot assure you that these measures may fully address the material weaknesses and deficiencies in our internal control over financial reporting or that we may conclude that they have been fully remediated.

        Upon completion of this offering, we will become subject to the Sarbanes-Oxley Act of 2002. Section 404 of the Sarbanes-Oxley Act, or Section 404, will require that we include a report from management on the effectiveness of our internal control over financial reporting in our annual report on Form 20-F beginning with our annual report in our second annual report on Form 20-F after becoming a public company. In addition, once we cease to be an "emerging growth company" as such term is defined in the JOBS Act, our independent registered public accounting firm must attest to and report on the effectiveness of our internal control over financial reporting. Moreover, even if our

30

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 an adverse opinion on the effectiveness of internal control over financial reporting because of the existence of a material weakness if it is not satisfied with our internal controls or the level at which our controls are documented, designed, operated or reviewed, or if it interprets the relevant requirements differently from us. In addition, after we become a public company, our reporting obligations may place a significant strain on our management, operational and financial resources and systems for the foreseeable future. We may be unable to timely complete our evaluation testing and any required remediation.

        During the course of documenting and testing our internal control procedures, in order to satisfy the requirements of Section 404, we may identify other weaknesses and deficiencies in our internal control over financial reporting. If we fail to maintain the adequacy of our internal control over financial reporting, as these standards are modified, supplemented or amended from time to time, we may not be able to conclude on an ongoing basis that we have effective internal control over financial reporting in accordance with Section 404. Generally speaking, if we fail to achieve and maintain an effective internal control environment, it could result in material misstatements in our financial statements and could also impair our ability to comply with applicable financial reporting requirements and related regulatory filings on a timely basis. As a result, our businesses, financial condition, results of operations and prospects, as well as the trading price of the ADSs, may be materially and adversely affected. Additionally, ineffective internal control over financial reporting could expose us to increased risk of fraud or misuse of corporate assets and subject us to potential delisting from the stock exchange on which we list, regulatory investigations and civil or criminal sanctions. We may also be required to restate our financial statements from prior periods.

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

        Our inventories are mostly coffee beans, coffee condiments and pre-made food and beverage items with short shelf life, which require us to manage our inventory effectively. We depend on our demand forecasts for various kinds of raw materials and pre-made products to make purchase decisions and to manage our inventory. Such demand, however, can change significantly between the time inventory is ordered and the date by which we hope to sell it. Demand may be affected by seasonality, new product launches, pricing and discounts, product defects, changes in customer spending patterns, changes in customer tastes and other factors, and our customers may not order products in the quantities that we expect. In addition, when we begin selling a new product, it may be difficult to establish supplier relationships, determine appropriate product selection, and accurately forecast demand. The acquisition of certain types of inventory may require significant lead time and prepayment and they may not be returnable.

        Furthermore, as we plan to continue expanding our product offerings, we expect to include a wider variety of products and raw materials in our inventory, which will make it more challenging for us to manage our inventory and logistics effectively. We cannot guarantee that our inventory levels will be able to meet the demands of customers, which may adversely affect our sales. We also cannot guarantee that all of our inventories can be consumed within its shelf life. If we fail to manage our inventory effectively, we may be subject to a heightened risk of inventory obsolescence, a decline in inventory value, and significant inventory write-downs or write-offs. Any of the above may materially and adversely affect our results of operations and financial condition. On the other hand, if we underestimate demand for our products, or if our suppliers fail to supply quality raw materials and pre-made products in a timely manner, we may experience inventory shortages, which might result in diminished brand loyalty and lost revenues, any of which could harm our business and reputation.

We have granted options in the past and will continue to grant share-based awards in the future, which may have an adverse effect on our future profit. Exercise of the share options granted will increase the number of our shares in circulation, which may adversely affect the market price of our shares.

        We adopted a share incentive plan in January 2019, which we refer to as the 2019 Share Option Plan, in this prospectus, to enhance our ability to attract and retain exceptionally qualified individuals and to encourage them to acquire a proprietary interest in the growth and performance of us. The maximum aggregate number of ordinary shares we are authorized to issue pursuant to all awards under the 2019 Share Option Plan is 158,031 ordinary shares. As of the date of this prospectus, 158,031 ordinary shares have been granted and outstanding under the 2019 Share Option Plan. See "Management—Share Incentive Plan."

        We believe the granting of share-based awards is of significant importance to our ability to attract and retain key personnel and employees, and we will continue to grant share-based compensation to employees in the future. As a result, our expenses associated with share-based compensation may increase, which may have an adverse effect on our results of operations.

The growth and profitability of our business depend on the level of customer demand and discretionary spending in China. A severe or prolonged downturn in China's economy could materially and adversely affect our business, financial condition and results of operations.

        China's coffee industry as well as China's food and beverage market in general is affected by macro-economic factors, including changes in international, national, regional and local economic conditions, employment levels, customer demand and discretionary spending. All of our stores are located in China and accordingly, our results of operations are affected by the macro-economic conditions in China. Any deterioration of the PRC economy, decrease in disposable customer income and fear of a recession may lead to a reduction of customer demand and average spending per customer at our stores, which could materially and adversely affect our business, financial condition and results of operations. Moreover, the occurrence of a financial crisis, sovereign debt crisis, banking crisis or other disruptions in the global financial markets may have a material and adverse impact on our operating results.

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

        We are vulnerable to natural disasters, health epidemics, and other calamities. Any of such occurrences could cause severe disruption to the daily operations of us, and may even require a temporary closure of facilities and logistics delivery networks, which may disrupt our business operations and adversely affect our results of operations. In addition, our results of operations could be adversely affected to the extent that any of these catastrophic events harm the Chinese economy in general.

We have no business liability or disruption insurance, which could expose us to significant costs and business disruption.

        The insurance industry in China is still at an early stage of development, and insurance companies in China currently offer limited business-related insurance products. We have no business liability or disruption insurance to cover our operations. Any uninsured risks may result in substantial costs and the diversion of resources, which could adversely affect our results of operations and financial condition.

Our business is subject to seasonal fluctuations and unexpected interruptions.

        We experience seasonality in our business. We generally experience fewer purchase orders during holiday seasons, such as the Chinese New Year holidays. Our financial condition and results of

operations for future quarters may continue to fluctuate and our historical quarterly results may not be comparable to future quarters. As a result, the trading price of the ADSs may fluctuate from time to time due to seasonality.

Risks Relating to Our Corporate Structure

We rely on contractual arrangements with our VIE to use, or otherwise benefit from, the foreign restricted licenses and permits, such as the ICP license. Any failure by our VIE or its shareholders to perform their obligations under our contractual arrangements with them would have a material and adverse effect on our business.

        We rely on contractual arrangements with our VIE to use, or otherwise benefit from, certain foreign restricted licenses and permits that we may need in the future as our business continues to expand, such as the internet content provider license, or the ICP license held by our VIE. The contractual arrangements contain terms that specifically obligate the VIE's shareholders to ensure the valid existence of the VIE and restrict the disposal of material assets of the VIE. However, These contractual arrangements may not be as effective as direct ownership in providing us with control over our VIE. For example, our VIE and its shareholders could breach their contractual arrangements with us by, among other things, failing to conduct their operations in an acceptable manner or taking other actions that are detrimental to our interests. In the event the VIE's shareholders breach the terms of these contractual arrangements and voluntarily liquidate our VIE, or our VIE declares bankruptcy and all or part of its assets become subject to liens or rights of third-party creditors, or are otherwise disposed of without our consent, we may be unable to conduct some or all of our business operations or otherwise benefit from the assets held by the VIE, which could have a material adverse effect on our business, financial condition and results of operations. Furthermore, if our VIE undergoes a voluntary or involuntary liquidation proceeding, its shareholders or unrelated third-party creditors may claim rights to some or all of the assets of the VIE, thereby hindering our ability to operate our business as well as constrain our growth.

Our business may be deemed as a foreign investment under the scheme of the Draft Foreign Investment Law (2015).

        On January 19, 2015, the PRC Ministry of Commerce, or MOFCOM, published the Draft Foreign Investment Law (2015). At the same time, MOFCOM published an accompanying explanatory note of the draft Foreign Investment Law (2015), which contains important information about the draft Foreign Investment Law (2015), including its drafting philosophy and principles, main table of contents, plans to transition to the new legal regime and treatment of business in China controlled by foreign-invested enterprises. The Draft Foreign Investment Law (2015) proposes significant changes to the PRC foreign investment legal regime and, when implemented, may have a significant impact on business in China controlled by foreign-invested enterprises primarily through contractual arrangements, such as our business. Please refer to "Regulation—Regulations on Foreign Investment" for further details. MOFCOM suggests both registration and approval as potential options for the regulation of variable interest entity structures, depending on whether they are "Chinese" or "foreign controlled." One of the core concepts of the draft Foreign Investment Law (2015) is "de facto control," which emphasizes substance over form in determining whether an entity is "Chinese" or "foreign-controlled. " "Chinese investors" are individuals who are Chinese nationals, Chinese government agencies and any domestic enterprise controlled by Chinese nationals or government agencies. "Foreign investors" are foreign citizens, foreign governments, international organizations and entities controlled by foreign citizens and entities.

        It is unclear whether our current corporate structure will be considered "Chinese" under the scheme of the Draft Foreign Investment Law (2015). In the event that our contractual arrangements with our VIE and shareholders of our VIE are not treated as a domestic investment and/or the foreign

33

Table of Contents

restricted licenses and permits held by the VIE are classified as a "prohibited business" in the Prohibited List or a "restricted business" in the Restricted List under the Draft Foreign Investment Law (2015) when officially enacted, such contractual arrangements may be deemed as invalid and illegal and we may be required to unwind the contractual arrangements and/or dispose of such business.

        In December 2018, the Standing Committee of the National People's Congress of PRC published the Draft Foreign Investment Law (2018) for public comments. On March 15, 2019, the Foreign Investment Law was formally issued, which will become effective on January 1, 2020. The Foreign Investment Law mainly focuses on foreign investment promotion, foreign investment protection and foreign investment management. Comparing with the draft Foreign Investment Law (2015), the Foreign Investment Law does not mention concepts including "De facto control" and "controlling PRC companies by contracts or trusts", nor did it specify the regulation on controlling through contractual arrangements.

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

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

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

        We are an exempted company incorporated under the laws of the Cayman Islands. Our corporate affairs are governed by our memorandum and articles of association, the Companies Law , Cap 22 (Law 3 of 1961, as consolidated and revised of the Cayman Islands and the common law of the Cayman Islands. The rights of shareholders to take action against our directors, actions by our minority shareholders and the fiduciary duties of our directors to us under Cayman Islands law are to a large extent governed by the common law of the Cayman Islands. The common law of the Cayman Islands is derived in part from comparatively limited judicial precedent in the Cayman Islands as well as from the common law of England, the decisions of whose courts are of persuasive authority, but are not binding, on a court in the Cayman Islands. The rights of our shareholders and the fiduciary duties of our directors under Cayman Islands law are not as clearly established as they would be under statutes or judicial precedent in some jurisdictions in the United States. In particular, the Cayman Islands have a less developed body of securities laws than the United States. Some U.S. states, such as Delaware, have more fully developed and judicially interpreted bodies of corporate law than the Cayman Islands. In addition, Cayman Islands companies may not have standings to initiate a shareholder derivative action in a federal court of the United States.

        Shareholders of Cayman Islands exempted companies like us have no general rights under Cayman Islands law to inspect corporate records or to obtain copies of lists of shareholders of these companies.

Table of Contents

Our directors have discretion under our articles of association that will become effective immediately prior to completion of this offering to determine whether or not, and under what conditions, our corporate records may be inspected by our shareholders, but are not obliged to make them available to our shareholders. This may make it more difficult for you to obtain the information needed to establish any facts necessary for a shareholder motion or to solicit proxies from other shareholders in connection with a proxy contest.

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

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

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

Risks Relating to Doing Business in China

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

        Substantially all of our assets and operations are located in China. Accordingly, our business, financial condition, results of operations and prospects may be influenced to a significant degree by political, economic and social conditions in China generally. The Chinese economy differs from the economies of most developed countries in many respects, including the level of government involvement, level of development, growth rate, control of foreign exchange and allocation of resources. Although the Chinese government has implemented measures emphasizing the utilization of market forces for economic reform, the reduction of state ownership of productive assets, and the establishment of improved corporate governance in business enterprises, a substantial portion of productive assets in China is still owned by the government. In addition, the Chinese government continues to play a significant role in regulating industry development by imposing industrial policies. The Chinese government also exercises significant control over China's economic growth through allocating resources, controlling payment of foreign currency-denominated obligations, setting monetary policy and providing preferential treatment to particular industries or companies.

        While the Chinese economy has experienced significant growth over past decades, growth has been uneven, both geographically and among various sectors of the economy. Any adverse changes in economic conditions in China, in the policies of the Chinese government or in the laws and regulations in China could have a material adverse effect on the overall economic growth of China. Such developments could adversely affect our business and operating results, lead to a reduction in demand for our products and adversely affect our competitive position. The Chinese government has implemented various measures to encourage economic growth and guide the allocation of resources.

35

Table of Contents

Some of these measures may benefit the overall Chinese economy, but may have a negative effect on us. For example, our financial condition and results of operations may be adversely affected by government control over capital investments or changes in tax regulations. In addition, in the past the Chinese government has implemented certain measures, including interest rate adjustment, to control the pace of economic growth. These measures may cause decreased economic activity in China, which may adversely affect our business and operating results.

Uncertainties with respect to the PRC legal system could adversely affect us.

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

        In 1979, the PRC government began to promulgate a comprehensive system of laws and regulations governing economic matters in general. The overall effect of legislation since then has significantly enhanced the protections afforded to various forms of foreign investments in China. However, China has not developed a fully integrated legal system, and recently enacted laws and regulations may not sufficiently cover all aspects of economic activities in China. In particular, the interpretation and enforcement of these laws and regulations involve uncertainties. Since PRC administrative and court authorities have significant discretion in interpreting and implementing statutory provisions and contractual terms, it may be difficult to evaluate the outcome of administrative and court proceedings and the level of legal protection we enjoy. These uncertainties may affect our judgment on the relevance of legal requirements and our ability to enforce our contractual rights or tort claims. In addition, the regulatory uncertainties may be exploited through unmerited or frivolous legal actions or threats in attempts to extract payments or benefits from us.

        Furthermore, the PRC legal system is based in part on government policies and internal rules, some of which are not published on a timely basis or at all and may have a retroactive effect. As a result, we may not be aware of our violation of any of these policies and rules until sometime after the violation. In addition, any administrative and court proceedings in China may be protracted, resulting in substantial costs and diversion of resources and management attention.

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

        We are a company incorporated under the laws of the Cayman Islands, we conduct substantially all of our operations in China, and substantially all of our assets are located in China. In addition, all our senior executive officers reside within China for a significant portion of the time and most are PRC nationals. As a result, it may be difficult for our shareholders to effect service of process upon us or those persons inside China. In addition, China does not have treaties providing for the reciprocal recognition and enforcement of judgments of courts with the Cayman Islands and many other countries and regions. Therefore, recognition and enforcement in China of judgments of a court in any of these non-PRC jurisdictions in relation to any matter not subject to a binding arbitration provision may be difficult or impossible.

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

        We are a Cayman Islands holding company and we rely principally on dividends and other distributions on equity from our PRC subsidiaries for our cash requirements, including for services of any debt we may incur.

36

Table of Contents

        Our PRC subsidiaries' ability to distribute dividends is based upon their distributable earnings. Current PRC regulations permit our PRC subsidiaries to pay dividends to their respective shareholders only out of their accumulated profits, if any, determined in accordance with PRC accounting standards and regulations. In addition, each of our PRC subsidiaries and our VIE are required to set aside at least 10% of its after-tax profits each year, if any, to fund a statutory reserve until such reserve reaches 50% of its registered capital. Each of our PRC subsidiaries as a Foreign Invested Enterprise, or FIE, is also required to further set aside a portion of its after-tax profits to fund the employee welfare fund, although the amount to be set aside, if any, is determined at its discretion. These reserves are not distributable as cash dividends. If our PRC subsidiaries incur debt on their own behalf in the future, the instruments governing the debt may restrict their ability to pay dividends or make other payments to us. Any limitation on the ability of our PRC subsidiaries to distribute dividends or other payments to their respective shareholders could materially and adversely limit our ability to grow, make investments or acquisitions that could be beneficial to our business, pay dividends or otherwise fund and conduct our business.

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

We may be subject to liability for placing advertisements with content that is deemed inappropriate or misleading under PRC laws.

        PRC laws and regulations prohibit advertising companies from producing, distributing or publishing any advertisement with content that violates PRC laws and regulations, impairs the national dignity of the PRC, involves designs of the PRC national flag, national emblem or national anthem or the music of the national anthem, is considered reactionary, obscene, superstitious or absurd, is fraudulent, or disparages similar products. We may be subject to claims by customers misled by information on our mobile apps, website or other portals where we put our advertisements on. We may not be able to recover our losses from advertisers by enforcing the indemnification provisions in the contracts, which may result us in diverting management's time and other resources from our business and operations to defend against these infringement claims. As a result, our business, financial condition and results of operations could be materially and adversely affected.

Our employment practices may be adversely impacted under the labor contract law of the PRC.

        The PRC National People's Congress promulgated the Labor Contract Law which became effective on January 1, 2008 and was amended on December 28, 2012, and the State Council promulgated implementing rules for the labor contract law on September 18, 2008. The labor contract law and the implementing rules impose requirements concerning, among others, the execution of written contracts between employers and employees, the time limits for probationary periods, and the length of employment contracts. The interpretation and implementation of these regulations are still evolving, our employment practices may violate the labor contract law and related regulations and we could be subject to penalties, fines or legal fees as a result. If we are subject to severe penalties or incur significant legal fees in connection with labor law disputes or investigations, our business, financial condition and results of operations may be adversely affected.

We may be subject to additional contributions of social insurance and housing fund and late payments and fines imposed by relevant governmental authorities.

        In accordance with the PRC Social Insurance Law and the Regulations on the Administration of Housing Fund and other relevant laws and regulations, China establishes a social insurance system and

37

Table of Contents

other employee benefits including basic pension insurance, basic medical insurance, work-related injury insurance, unemployment insurance, maternity insurance, housing fund, and a handicapped employment security fund, or collectively the Employee Benefits. An employer shall pay the Employee Benefits for its employees in accordance with the rates provided under relevant regulations and shall withhold the social insurance and other Employee Benefits that should be assumed by the employees. For example, an employer that has not made social insurance contributions at a rate and based on an amount prescribed by the law, or at all, may be ordered to rectify the non-compliance and pay the required contributions within a stipulated deadline and be subject to a late fee of up to 0.05% or 0.2% per day, as the case may be. If the employer still fails to rectify the failure to make social insurance contributions within the stipulated deadline, it may be subject to a fine ranging from one to three times of the amount overdue.

        Under the Social Insurance Law and the Regulations on the Administration of Housing Fund, PRC subsidiaries shall register with local social insurance agencies and register with applicable housing fund management centers and establish a special housing fund account in an entrusted bank. Both PRC subsidiaries and their employees are required to contribute to the Employee Benefits.

        As of the date of this prospectus, some of our PRC subsidiaries are in the process of completing the social insurance registration and the housing fund registration, and we have not made adequate contributions to Employee Benefits for some of our employees. We have recorded accruals for the estimated underpaid amounts of Employee Benefits in our financial statements. As of the date of this prospectus, we have not received any notice from the relevant government authorities or any claim or request from these employees in this regard. However, we cannot assure you that the relevant government authorities will not require us to pay the outstanding amount and impose late fees or fines on us. If we fail to make the outstanding Employee Benefit contributions within the prescribed time frame, we may be subject to a fine of up to three times the amount of the overdue payment. If we are otherwise subject to investigations related to non-compliance with labor laws and are imposed severe penalties or incur significant legal fees in connection with labor law disputes or investigations, our business, financial condition and results of operations may be adversely affected.

Non-compliance with labor-related laws and regulations of the PRC may have an adverse impact on our financial condition and results of operation.

        We have been subject to stricter regulatory requirements in terms of entering into labor contracts with our employees and paying various statutory employee benefits, including pensions, housing fund, medical insurance, work-related injury insurance, unemployment insurance and childbearing insurance to designated government agencies for the benefit of our employees. Pursuant to the PRC Labor Contract Law, or the Labor Contract Law, that became effective in January 2008 and its implementing rules that became effective in September 2008 and was amended in July 2013, employers are subject to stricter requirements in terms of signing labor contracts, minimum wages, paying remuneration, determining the term of employees' probation and unilaterally terminating labor contracts. In the event that we decide to terminate some of our employees or otherwise change our employment or labor practices, the Labor Contract Law and its implementation rules may limit our ability to effect those changes in a desirable or cost-effective manner, which could adversely affect our business and results of operations. In addition, we engage a small number of dispatched workers from third-party employment agencies as baristas and other storefront staff. Pursuant to the Labor Contract Law and its amendments, dispatched workers may only be engaged for temporary, ancillary or substitute positions. We believe our current practice complies with the Labor Contract Law and its amendments. However, the relevant governmental authorities may take a different view and impose fines on us.

        As the interpretation and implementation of labor-related laws and regulations are still evolving, we cannot assure you that our employment practice does not and will not violate labor-related laws and regulations in China, which may subject us to labor disputes or government investigations. If we are

38

deemed to have violated relevant labor laws and regulations, we could be required to provide additional compensation to our employees and our business, financial condition and results of operations could be materially and adversely affected.

The custodians or authorized users of our controlling non-tangible assets, including chops and seals, may fail to fulfill their responsibilities, or misappropriate or misuse these assets.

        Under PRC law, legal documents for corporate transactions, including agreements and contracts are executed using the chop or seal of the signing entity or with the signature of a legal representative whose designation is registered and filed with relevant PRC industry and commerce authorities.

        In order to secure the use of our chops and seals, we have established internal control procedures and rules for using these chops and seals. In any event that the chops and seals are intended to be used, the responsible personnel will submit the application through our office automation system and the application will be verified and approved by authorized employees in accordance with our internal control procedures and rules. In addition, in order to maintain the physical security of our chops, we generally have them stored in secured locations accessible only to authorized employees. Although we monitor such authorized employees, the procedures may not be sufficient to prevent all instances of abuse or negligence. There is a risk that our employees could abuse their authority, for example, by entering into a contract not approved by us or seeking to gain control of one of our subsidiaries or consolidated VIE. If any employee obtains, misuses or misappropriates our chops and seals or other controlling non-tangible assets for whatever reason, we could experience disruption to our normal business operations, and we may have to take corporate or legal action, which could involve significant time and resources to resolve and divert management from our operations.

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

        Any funds we transfer to our PRC subsidiaries, either as a shareholder loan or as an increase in registered capital, are subject to approval by or registration with relevant governmental authorities in China. According to the relevant PRC regulations on FIEs in China, capital contributions to our PRC subsidiaries are subject to the approval of or filing with the MOFCOM or their respective local branches and registration with a local bank authorized by the State Administration of Foreign Exchange, or SAFE. In addition, (i) any foreign loan procured by our PRC subsidiaries is required to be registered with SAFE or their respective local branches and (ii) our PRC subsidiaries may not procure loans which exceed the difference between their respective total investment amount and registered capital. Any medium or long-term loan to be provided by us to our VIE must be registered with the NDRC and the SAFE or its local branches. We may not be able to complete such registrations on a timely basis, with respect to future capital contributions or foreign loans by us to our PRC subsidiaries. If we fail to complete such registrations, our ability to use the proceeds of this offering and to capitalize our PRC operations may be negatively affected, which could adversely affect our liquidity and our ability to fund and expand our business.

        On March 30, 2015, the SAFE promulgated the Circular on Reforming the Management Approach Regarding the Foreign Exchange Capital Settlement of Foreign-Invested Enterprises, or SAFE Circular 19, which took effect as of June 1, 2015. SAFE Circular 19 launched a nationwide reform of the administration of the settlement of the foreign exchange capitals of FIEs and allows FIEs to settle their foreign exchange capital at their discretion, but continues to prohibit FIEs from using the Renminbi fund converted from their foreign exchange capital for expenditure beyond their business scopes, providing entrusted loans or repaying loans between nonfinancial enterprises. The SAFE issued the Circular on Reforming and Regulating Policies on the Control over Foreign Exchange Settlement

39

Table of Contents

of Capital Accounts, or SAFE Circular 16, effective in June 2016. Pursuant to SAFE Circular 16, enterprises registered in China may also convert their foreign debts from foreign currency to Renminbi on a self-discretionary basis. SAFE Circular 16 provides an integrated standard for conversion of foreign exchange under capital account items (including but not limited to foreign currency capital and foreign debts) on a self-discretionary basis which applies to all enterprises registered in China. SAFE Circular 16 reiterates the principle that Renminbi converted from foreign currency-denominated capital of a company may not be directly or indirectly used for purposes beyond its business scope or prohibited by PRC laws or regulations, while such converted Renminbi shall not be provided as loans to its non-affiliated entities. As this circular is relatively new, there remains uncertainty as to its interpretation and application and any other future foreign exchange related rules. Violations of these Circulars could result in severe monetary or other penalties. SAFE Circular 19 and SAFE Circular 16 may significantly limit our ability to use Renminbi converted from the net proceeds of this offering to fund the establishment of new entities in China by our VIE, to invest in or acquire any other PRC companies through our PRC subsidiaries, or to establish new consolidated VIEs in China, which may adversely affect our business, financial condition and results of operations.

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

        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 government. It is difficult to predict how long such depreciation of RMB against the U.S. dollar may last and when and how the relationship between the RMB and the U.S. dollar may change again. All of our revenues and substantially all of our costs are denominated in Renminbi. 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 Renminbi may materially and adversely affect our results of operations and financial position reported in Renminbi when translated into U.S. dollars, and the value of, and any dividends payable on, the ADSs in U.S. dollars. To the extent that we need to convert U.S. dollars we receive 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 ordinary shares or the 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.

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

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

to entities outside China, or to make other capital expenditure payments outside China in a currency other than Renminbi. The PRC government may at its discretion restrict access to foreign currencies for current account transactions in the future. If the foreign exchange control system prevents us from obtaining sufficient foreign currencies to satisfy our foreign currency demands, we may not be able to pay dividends in foreign currencies to our shareholders, including holders of the ADSs.

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

        Among other things, the Regulations on Mergers and Acquisitions of Domestic Enterprises by Foreign Investors, or the M&A Rules, adopted by six PRC regulatory agencies in 2006 and amended in 2009, established additional procedures and requirements that could make merger and acquisition activities by foreign investors more time-consuming and complex. Such regulation requires, among other things, that the MOFCOM be notified in advance of any change-of-control transaction in which a foreign investor acquires control of a PRC domestic enterprise or a foreign company with substantial PRC operations, if certain thresholds under the Provisions on Thresholds for Prior Notification of Concentrations of Undertakings, issued by the State Council in 2008, are triggered. Moreover, the Anti-Monopoly Law promulgated by the Standing Committee of the NPC which became effective in 2008 requires that transactions which are deemed concentrations and involve parties with specified turnover thresholds must be cleared by the MOFCOM before they can be completed. In addition, PRC national security review rules which became effective in September 2011 require acquisitions by foreign investors of PRC companies engaged in military-related or certain other industries that are crucial to national security be subject to security review before consummation of any such acquisition. We may pursue potential strategic acquisitions that are complementary to our business and operations. Complying with the requirements of these regulations to complete such transactions could be time-consuming, and any required approval processes, including obtaining approval or clearance from the MOFCOM, may delay or inhibit our ability to complete such transactions, which could affect our ability to expand our business or maintain our market share.

PRC regulations relating to the establishment of offshore special purpose companies by PRC residents may subject our PRC resident beneficial owners or our PRC subsidiaries to liability or penalties, limit our ability to inject capital into our PRC subsidiaries, limit our PRC subsidiaries' ability to increase their registered capital or distribute profits to us, or may otherwise adversely affect us.

        In July 2014, SAFE promulgated the Circular on Relevant Issues Concerning Foreign Exchange Control on Domestic Residents' Offshore Investment and Financing and Roundtrip Investment Through Special Purpose Vehicles, or SAFE Circular 37, to replace the Notice on Relevant Issues Concerning Foreign Exchange Administration for Domestic Residents' Financing and Roundtrip Investment Through Offshore Special Purpose Vehicles, or SAFE Circular 75, which ceased to be effective upon the promulgation of SAFE Circular 37. SAFE Circular 37 requires PRC residents (including PRC individuals and PRC corporate entities) to register with SAFE or its local branches in connection with their direct or indirect offshore investment activities. SAFE Circular 37 is applicable to our shareholders who are PRC residents and may be applicable to any offshore acquisitions that we make in the future.

        Under SAFE Circular 37, PRC residents who make, or have prior to the implementation of SAFE Circular 37 made, direct or indirect investments in offshore special purpose vehicles, or SPVs, will be required to register such investments with SAFE or its local branches. In addition, any PRC resident who is a direct or indirect shareholder of an SPV is required to update its filed registration with the local branch of SAFE with respect to that SPV, to reflect any material change. Moreover, any subsidiary of such SPV in China is required to urge the PRC resident shareholders to update their registration with the local branch of SAFE. If any PRC shareholder of such SPV fails to make the required registration or to update the previously filed registration, the subsidiary of such SPV in China

41

Table of Contents

may be prohibited from distributing its profits or the proceeds from any capital reduction, share transfer or liquidation to the SPV, and the SPV may also be prohibited from making additional capital contributions into its subsidiary in China. On February 13, 2015, the SAFE promulgated a Notice on Further Simplifying and Improving Foreign Exchange Administration Policy on Direct Investment, or SAFE Notice 13, which became effective on June 1, 2015. Under SAFE Notice 13, applications for foreign exchange registration of inbound foreign direct investments and outbound overseas direct investments, including those required under SAFE Circular 37, will be filed with qualified banks instead of SAFE. The qualified banks will directly examine the applications and accept registrations under the supervision of SAFE.

        Some of our shareholders that we are aware of are subject to SAFE regulations, and we expect all of these shareholders will have completed all necessary registrations with the local SAFE branch or qualified banks as required by SAFE Circular 37 immediately before completion of this offering. We cannot assure you, however, that all of these individuals may continue to make required filings or updates in a timely manner, or at all. We can provide no assurance that we are or will in the future continue to be informed of identities of all PRC residents holding direct or indirect interest in our company. Any failure or inability by such individuals to comply with SAFE regulations may subject us to fines or legal sanctions, such as restrictions on our cross-border investment activities or our PRC subsidiaries' ability to distribute dividends to, or obtain foreign exchange-denominated loans from, our company or prevent us from making distributions or paying dividends. As a result, our business operations and our ability to make distributions to you could be materially and adversely affected.

        Furthermore, as these foreign exchange regulations are still relatively new and their interpretation and implementation have been constantly evolving, it is unclear how these regulations, and any future regulation concerning offshore or cross-border transactions, will be interpreted, amended and implemented by the relevant government authorities. For example, we may be subject to a more stringent review and approval process with respect to our foreign exchange activities, such as remittance of dividends and foreign-currency-denominated borrowings, which may adversely affect our financial condition and results of operations. In addition, if we decide to acquire a PRC domestic company, we cannot assure you that we or the owners of such company, as the case may be, will be able to obtain the necessary approvals or complete the necessary filings and registrations required by the foreign exchange regulations. This may restrict our ability to implement our acquisition strategy and could adversely affect our business and prospects.

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

        In February 2012, SAFE promulgated the Notices on Issues Concerning the Foreign Exchange Administration for Domestic Individuals Participating in Stock Incentive Plan of Overseas Publicly Listed Company, replacing earlier rules promulgated in 2007. Pursuant to these rules, PRC citizens and non-PRC citizens who reside in China for a continuous period of not less than one year who participate in any stock incentive plan of an overseas publicly listed company, subject to a few exceptions, are required to register with SAFE through a domestic qualified agent, which could be the PRC subsidiaries of such overseas-listed company, and complete certain other procedures. In addition, an overseas-entrusted institution must be retained to handle matters in connection with the exercise or sale of stock options and the purchase or sale of shares and interests. We and our executive officers and other employees who are PRC citizens or who reside in the PRC for a continuous period of not less than one year and who have been granted options will be subject to these regulations when our company becomes an overseas-listed company upon completion of this offering. Failure to complete the SAFE registrations may subject them to fines and legal sanctions, there may be additional restrictions on the ability of them to exercise their stock options or remit proceeds gained from the sale of their

stock into the PRC. We also face regulatory uncertainties that could restrict our ability to adopt incentive plans for our directors, executive officers and employees under PRC law. See "Regulation—Regulations Relating to Stock Incentive Plans."

Any adverse change in our tax treatment could have a material and adverse impact on our business and results of operations.

        Our products and services are subject to value-added tax, or VAT from 6% to 16%. We also accrue for VAT relating to certain promotion initiatives, which amounted to RMB 0.02 million for the period from June 16, 2017 (inception date) to December 31, 2017 and RMB3.8 million in 2018. If the tax authority has a different view on our VAT accounting treatment, our results of operations may be adversely affected.

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

        Under the PRC Enterprise Income Tax Law and its implementation rules, an enterprise established outside of the PRC with its "de facto management body" within the PRC is considered a "resident enterprise" and will be subject to the enterprise income tax on its global income at the rate of 25%. The implementation rules define the term "de facto management body" as the body that exercises full and substantial control and overall management over the business, productions, personnel, accounts and properties of an enterprise. In 2009, the State Administration of Taxation, or SAT, issued a circular, known as SAT Circular 82, which provides certain specific criteria for determining whether the "de facto management body" of a PRC-controlled enterprise that is incorporated offshore is located in China. Although this circular applies only to offshore enterprises controlled by PRC enterprises or PRC enterprise groups, not those controlled by PRC individuals or foreigners, the criteria set forth in the circular may reflect the SAT's general position on how the "de facto management body" text should be applied in determining the tax resident status of all offshore enterprises. According to SAT Circular 82, an offshore incorporated enterprise controlled by a PRC enterprise or a PRC enterprise group will be regarded as a PRC tax resident by virtue of having its "de facto management body" in China, and will be subject to PRC enterprise income tax on its global income only if all of the following conditions are met: (i) the primary location of the day-to-day operational management is in the PRC; (ii) decisions relating to the enterprise's financial and human resource matters are made or are subject to approval by organizations or personnel in the PRC; (iii) the enterprise's primary assets, accounting books and records, company seals, and board and shareholder resolutions are located or maintained in the PRC; and (iv) at least 50% of voting board members or senior executives habitually reside in the PRC.

        We believe our company is not a PRC resident enterprise for PRC tax purposes. However, the tax resident status of an enterprise is subject to determination by the PRC tax authorities and uncertainties remain with respect to the interpretation of the term "de facto management body." If the PRC tax authorities determine that our company is a PRC resident enterprise for enterprise income tax purposes, we would be subject to PRC enterprise income on our worldwide income at the rate of 25%. Furthermore, we would be required to withhold a 10% tax from dividends we pay to our shareholders that are non-resident enterprises, including the holders of the ADSs. In addition, non-resident enterprise shareholders (including the ADS holders) may be subject to PRC tax on gains realized on the sale or other disposition of the ADSs or ordinary shares, if such income is treated as sourced from within the PRC. Furthermore, if we are deemed a PRC resident enterprise, dividends paid to our non-PRC individual shareholders (including the ADS holders) and any gain realized on the transfer of the ADSs or ordinary shares by such shareholders may be subject to PRC tax at a rate of 20% (which, in the case of dividends, may be withheld at source by us). These rates may be reduced by an applicable tax treaty, but it is unclear whether non-PRC shareholders of our company would be able to claim the benefits of any tax treaties between their country of tax residence and the PRC in the event

that we are treated as a PRC resident enterprise. Any such tax may reduce the returns on your investment in the ADSs or ordinary shares.

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

        On February 3, 2015, the SAT issued the Public Notice Regarding Certain Corporate Income Tax Matters on Indirect Transfer of Properties by Non-Tax Resident Enterprises, or SAT Bulletin 7. SAT Bulletin 7 extends its tax jurisdiction to transactions involving the transfer of taxable assets through offshore transfer of a foreign intermediate holding company. In addition, SAT Bulletin 7 has introduced safe harbors for internal group restructurings and the purchase and sale of equity through a public securities market. SAT Bulletin 7 also brings challenges to both foreign transferor and transferee (or other person who is obligated to pay for the transfer) of taxable assets, as such persons need to determine whether their transactions are subject to these rules and whether any withholding obligation applies.

        On October 17, 2017, the SAT issued the Announcement of the State Administration of Taxation on Issues Concerning the Withholding of Non-resident Enterprise Income Tax at Source, or SAT Bulletin 37, which came into effect on December 1, 2017. The SAT Bulletin 37 further clarifies the practice and procedure of the withholding of non-resident enterprise income tax.

        Where a non-resident enterprise transfers taxable assets indirectly by disposing of the equity interests of an overseas holding company, which is an Indirect Transfer, the non-resident enterprise as either transferor or transferee, or the PRC entity that directly owns the taxable assets, may report such Indirect Transfer to the relevant tax authority. Using a "substance over form" principle, the PRC tax authority may disregard the existence of the overseas holding company if it lacks a reasonable commercial purpose and was established for the purpose of reducing, avoiding or deferring PRC tax. As a result, gains derived from such Indirect Transfer may be subject to PRC enterprise income tax, and the transferee or other person who pays for the transfer is obligated to withhold the applicable taxes currently at a rate of 10% for the transfer of equity interests in a PRC resident enterprise. Both the transferor and the transferee may be subject to penalties under PRC tax laws if the transferee fails to withhold the taxes and the transferor fails to pay the taxes.

        We face uncertainties as to the reporting and other implications of certain past and future transactions where PRC taxable assets are involved, such as offshore restructuring, sale of the shares in our offshore subsidiaries and investments. Our company may be subject to filing obligations or taxed if our company is transferor in such transactions, and may be subject to withholding obligations if our company is transferee in such transactions, under SAT Bulletin 7 and/or SAT Bulletin 37. For transfer of shares in our company by investors who are non-PRC resident enterprises, our PRC subsidiaries may be requested to assist in the filing under SAT Bulletin 7 and/or SAT Bulletin 37. As a result, we may be required to expend valuable resources to comply with SAT Bulletin 7 and/or SAT Bulletin 37 or to request the relevant transferors from whom we purchase taxable assets to comply with these circulars, or to establish that our company should not be taxed under these circulars, which may have a material adverse effect on our financial condition and results of operations.

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

        Our independent registered public accounting firm that issues the audit report included in this prospectus, as an auditor of companies that are traded publicly in the United States and a firm registered with the Public Company Accounting Oversight Board, or the PCAOB, is required by the laws of the United States to undergo regular inspections by the PCAOB to assess its compliance with the laws of the United States and professional standards. Since our auditors are located in China, a jurisdiction where the PCAOB is currently unable to conduct inspections without the approval of the Chinese authorities, our auditors are not currently inspected by the PCAOB.

44

Table of Contents

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

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

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

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

        In late 2012, this impasse led the SEC to commence administrative proceedings under Rule 102E of its Rules of Practice and also under the Sarbanes-Oxley Act of 2002 against the Chinese accounting firms, including our independent registered public accounting firm. A first instance trial of the proceedings in July 2013 in the SEC's internal administrative court resulted in an adverse judgment against the firms. The administrative law judge proposed penalties on the firms including a temporary suspension of their right to practice before the SEC, although that proposed penalty did not take effect pending review by the Commissioners of the SEC. On February 6, 2015, before a review by the Commissioner had taken place, the firms reached a settlement with the SEC. Under the settlement, the SEC accepts that future requests by the SEC for the production of documents will normally be made to the CSRC. The firms will receive matching Section 106 requests, and are required to abide by a detailed set of procedures with respect to such requests, which in substance require them to facilitate production via the CSRC. If they fail to meet specified criteria, the SEC retains authority to impose a variety of additional remedial measures on the firms depending on the nature of the failure. Remedies for any future noncompliance could include, as appropriate, an automatic six-month bar on a single firm's performance of certain audit work, commencement of a new proceeding against a firm, or, in extreme cases, the resumption of the current proceeding against all four firms. If additional remedial measures are imposed on the Chinese affiliates of the "big four" accounting firms, including our independent registered public accounting firm, in administrative proceedings brought by the SEC alleging the firms' failure to meet specific criteria set by the SEC with respect to requests for the production of documents, we could be unable to timely file future financial statements in compliance with the requirements of the Exchange Act.

        If our independent registered public accounting firm was denied, even temporarily, the ability to practice before the SEC and we were unable to timely find another registered public accounting firm to audit and issue an opinion on our financial statements, our financial statements could be determined not to be in compliance with the requirements of the Exchange Act. Such a determination could ultimately lead to the delisting of the ADSs from the NASDAQ or deregistration from the SEC, or both, which would substantially reduce or effectively terminate the trading of the ADSs in the United States.

Regulation and censorship of information disseminated over the internet in China may adversely affect our business and reputation and subject us to liability for information displayed on our website.

        The PRC government has adopted regulations governing internet access and the distribution of news and other information over the internet. Under these regulations, internet content providers and internet publishers are prohibited from posting or displaying over the internet content that, among other things, violates PRC laws and regulations, impairs the national dignity of China, or is reactionary, obscene, superstitious, fraudulent or defamatory. Failure to comply with these requirements may result in the revocation of licenses to provide internet content and other licenses, and the closure of the concerned websites. The website operator may also be held liable for such censored information displayed on or linked to the websites. If our website is found to be in violation of any such requirements, we may be penalized by relevant authorities, and our operations or reputation could be adversely affected.

Risks Relating to the ADSs and This Offering

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

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

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

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

•

variations in our revenues, earnings and cash flows;



•

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



•

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



•

changes in financial estimates by securities analysts;



•

detrimental adverse publicity about us, our products and services or our industry;



•

announcements of new regulations, rules or policies relevant for our business;



•

additions or departures of key personnel;



•

release of lockup or other transfer restrictions on our outstanding equity securities or sales of additional equity securities; and



•

potential litigation or regulatory investigations.

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

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

Substantial future sales or perceived potential sales of ADSs in the public market could cause the price of ADSs to decline.

        Sales of substantial amounts of ADSs in the public market after completion of this offering, or the perception that these sales could occur, could adversely affect the market price of ADSs. In connection with this offering, [we, our officers and directors and all of our existing shareholders and option holders have agreed not to sell any ordinary shares or ADSs for 180 days after the date of this prospectus without the prior written consent of the representatives of the underwriters]. Upon completion of this offering, we will have        ordinary shares outstanding, including ordinary shares represented by ADSs, assuming the underwriters do not exercise their option to purchase additional ADSs. The ADSs sold in this offering will be freely tradable without restriction or further registration under the Securities Act. The remaining ordinary shares outstanding immediately after this offering will be available for sale, upon the expiration of the 180-day lock-up period, subject to volume and other restrictions as applicable under Rules 144 and 701 under the Securities Act. In addition, the underwriters may exercise the discretion to release the securities held by the parties subject to the lock-up restriction prior to the expiration of the lock-up period. If the securities subject to lock-up are released before the expiration of the lock-up period, their sale or perceived sale into the market may cause the price of ADSs to decline. See "Underwriting" and "Shares Eligible for Future Sale" for a more detailed description of the restrictions on selling our securities after this offering.

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

        Holders of the ADSs do not have the same rights as our registered shareholders. As a holder of the ADSs, you will not have any direct right to attend general meetings of our shareholders or to cast any votes at such meetings. You will only be able to exercise the voting rights which attach to the Class A ordinary shares underlying the ADSs indirectly by giving voting instructions to the depositary in accordance with the provisions of the deposit agreement. Under the deposit agreement, you may vote only by giving voting instructions to the depositary, as holder of the Class A ordinary shares underlying the ADSs. If we ask for your instructions, then upon receipt of your voting instructions, the depositary will try to vote the underlying Class A ordinary shares in accordance with those instructions. If we do not instruct the depositary to ask for your instructions, you can still give instructions, and the depositary may vote in accordance with instructions you give, but it is not required to do so. You will not be able to directly exercise any right to vote with respect to the underlying Class A ordinary shares unless you withdraw the shares and become the registered holder of such shares prior to the record date for the general meeting. When a general meeting is convened, you may not receive sufficient advance notice of the meeting to enable you to withdraw the shares underlying the ADSs and become the registered holder of such shares prior to the record date for the general meeting to allow you to attend the general meeting and to vote directly with respect to any specific matter or resolution to be considered and voted upon at the general meeting. In addition, under our fourth amended and restated articles of

47

Table of Contents

association that will become effective immediately prior to completion of this offering, for the purposes of determining those shareholders who are entitled to attend and vote at any general meeting, our directors may close our register of members and/or fix in advance a record date for such meeting, and such closure of our register of members or the setting of such a record date may prevent you from withdrawing the Class A ordinary shares underlying the ADSs and becoming the registered holder of such shares prior to the record date, so that you would not be able to attend the general meeting or to vote directly. Where any matter is to be put to a vote at a general meeting, the depositary will notify you of the upcoming vote and to deliver our voting materials to you if we ask it to. We cannot assure you that you will receive the voting material in time to ensure you can direct the depositary to vote your shares. In addition, the depositary and its agents are not responsible for failing to carry out voting instructions or for their manner of carrying out your voting instructions. This means that you may not be able to exercise your right to direct how the shares underlying the ADSs are voted and you may have no legal remedy if the shares underlying the ADSs are not voted as you requested.

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

        We [have adopted] a dual-class share structure such that our ordinary shares will consist of Class A ordinary shares and Class B ordinary shares, which will become effective immediately upon the completion of this offering. In respect of matters requiring the votes of shareholders, each Class A ordinary share is entitled to one vote and each Class B ordinary share is entitled to ten votes. Each Class B ordinary share is convertible into one Class A ordinary share at any time by the holder thereof. Class A ordinary shares are not convertible into Class B ordinary shares under any circumstances. We will sell Class A ordinary shares represented by our ADSs in this offering.

        Immediately upon the completion of this offering, the Pre-IPO Shareholders will beneficially own all of our issued and outstanding Class B ordinary shares. Based on an assumed initial public offering price of US$            per ADS, the mid-point of the estimated public offering price range shown on the front cover of this prospectus, these Class B ordinary shares will constitute approximately        % of our total issued and outstanding share capital and        % of the aggregate voting power of our total issued and outstanding share capital immediately upon the completion of this offering, assuming the underwriters do not exercise their over-allotment option.

        As a result of this dual-class share structure, the holders of our Class B ordinary shares will have concentrated control over the outcome of matters put to a vote of shareholders and have significant influence over our business, including decisions regarding mergers, consolidations, liquidations and the sale of all or substantially all of our assets, election of directors and other significant corporate actions. The holders of Class B ordinary shares may take actions that are not in the best interest of us or our other shareholders or holders of the ADSs. This concentration of ownership may discourage, delay or prevent a change in control of our company, which could have the effect of depriving our other shareholders of the opportunity to receive a premium for their shares as part of a sale of our company and may reduce the price of the ADSs. This concentrated control will limit your ability to influence corporate matters and could discourage others from pursuing any potential merger, takeover or other change of control transactions that holders of Class A ordinary shares and ADSs may view as beneficial.

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

        We currently intend to retain most, if not all, of our available funds and any future earnings after this offering to fund the development and growth of our business. As a result, we do not expect to pay

48

Table of Contents

any cash dividends in the foreseeable future. Therefore, you should not rely on an investment in the ADSs as a source for any future dividend income.

Because the initial public offering price is substantially higher than the pro forma net tangible book value per share, you will experience immediate and substantial dilution.

        If you purchase the ADSs in this offering, you will pay more for each ADS than the corresponding amount paid by existing shareholders for their ordinary shares. In addition, in June 2018, in connection with a loan facility extended by TTCO Trust Corporation Limited, or TTCO, to us, we granted TTCO a warrant to make equity investment in our company up to RMB60 million with an exercise price equal to 1.6 times of the issue price of our Series A convertible redeemable preferred shares, subject to adjustment, and such warrant will expire upon the public filing of our initial public offering or in case that we are acquired by or merged into other entities. See "Management's Discussion and Analysis of Financial Condition and Results of Operations—Contractual Obligations." As a result, you will experience immediate and substantial dilution of approximately US$            per ADS, assuming that no outstanding options to acquire ordinary shares are exercised. This number represents the difference between the initial public offering price of US$            per ADS, and our pro forma net tangible book value per ADS as of            , 2019, after giving effect to this offering. You may experience further dilution to the extent that our ordinary shares are issued upon exercise of any share options. See "Dilution" for a more complete description of how the value of your investment in ADSs will be diluted upon completion of this offering.

Techniques employed by short sellers may drive down the market price of the ADSs.

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

        Public companies that have substantially all of their operations in China have been the subject of short selling. Much of the scrutiny and negative publicity has centered on allegations of a lack of effective internal control over financial reporting resulting in financial and accounting irregularities and mistakes, inadequate corporate governance policies or a lack of adherence thereto and, in many cases, allegations of fraud. As a result, many of these companies are now conducting internal and external investigations into the allegations and, in the interim, are subject to shareholder lawsuits and/or SEC enforcement actions.

        It is not clear what effect such negative publicity could have on us. If we were to become the subject of any unfavorable allegations, whether such allegations are proven to be true or untrue, we could have to expend a significant amount of resources to investigate such allegations and/or defend ourselves. While we would strongly defend against any such short seller attacks, we may be constrained in the manner in which we can proceed against the relevant short seller by principles of freedom of speech, applicable state law or issues of commercial confidentiality. Such a situation could be costly and time-consuming, and could distract our management from growing our business. Even if such allegations are ultimately proven to be groundless, allegations against us could severely impact our business operations, and any investment in the ADSs could be greatly reduced or even rendered worthless.

If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business, the market price for the ADSs and trading volume could decline.

        The trading market for the ADSs will depend in part on the research and reports that securities or industry analysts publish about us or our business. If research analysts do not establish and maintain adequate research coverage or if one or more of the analysts who covers us downgrades the ADSs or publishes inaccurate or unfavorable research about our business, the market price for the ADSs would likely decline. If one or more of these analysts cease coverage of our company or fail to publish reports on us regularly, we could lose visibility in the financial markets, which, in turn, could cause the market price or trading volume for the ADSs to decline.

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

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

Our post-IPO memorandum and articles of association that will become effective immediately prior to completion of this offering contain anti-takeover provisions that could have a material adverse effect on the rights of holders of our ordinary shares and the ADSs.

        We [have adopted] the fourth amended and restated memorandum and articles of association that will become effective immediately prior to completion of this offering. Our post-IPO memorandum and articles of association will contain provisions which could limit the ability of others to acquire control of our company or cause us to engage in change-of-control transactions. These provisions could have the effect of depriving our shareholders of an opportunity to sell their shares at a premium over prevailing market prices by discouraging third parties from seeking to obtain control of our company in a tender offer or similar transaction. For example, our board of directors has the authority subject to any resolution of the shareholders to the contrary, to issue preferred shares in one or more series and to fix their designations, powers, preferences, privileges, and relative participating, optional or special rights and the qualifications, limitations or restrictions, including dividend rights, conversion rights, voting rights, terms of redemption and liquidation preferences, any or all of which may be greater than the rights associated with our ordinary shares. Preferred shares could be issued quickly with terms calculated to delay or prevent a change in control of our company or make removal of management more difficult. If our board of directors decides to issue preferred shares, the price of the ADSs may fall and the voting and other rights of the holders of our ordinary shares and the ADSs may be materially and adversely affected.

The approval of the China Securities Regulatory Commission may be required in connection with this offering under PRC law.

        The M&A Rules purport to require offshore special purpose vehicles that are controlled by PRC companies or individuals and that have been formed for the purpose of seeking a public listing on an overseas stock exchange through acquisitions of PRC domestic companies or assets to obtain CSRC approval prior to publicly listing their securities on an overseas stock exchange. In September 2006, the CSRC published a notice on its official website specifying documents and materials required to be

50

Table of Contents

submitted to it by a special purpose vehicle seeking CSRC approval of its overseas listings. The interpretation and application of the regulations remain unclear. If CSRC approval is required, it is uncertain whether it would be possible for us to obtain the approval, and any failure to obtain or delay in obtaining CSRC approval for this offering would subject us to sanctions imposed by the CSRC and other PRC regulatory agencies.

        King & Wood Mallesons, our PRC legal counsel, has advised us that, based on its understanding of the current PRC laws and regulations, we will not be required to submit an application to the CSRC for the approval of the listing and trading of the ADSs on the NASDAQ because (i) the CSRC currently has not issued any definitive rule or interpretation concerning whether offering such as this offering contemplated by our Company are subject to the M&A Rules; (ii) the PRC Subsidiaries were incorporated as wholly foreign-owned enterprises by means of direct investment rather than by merger or acquisition of equity interest or assets of a PRC domestic company owned by PRC companies or individuals as defined under the M&A Rules that are our Company's beneficial owners; and (iii) there is no provision in the M&A Rules that clearly classifies the Contractual arrangements as a kind of merger and acquisition transaction falling under the M&A Rules.

        However, our PRC legal counsel has further advised us that there are substantial uncertainty as to how the M&A Rules will be interpreted or implemented in the context of an overseas offering, and its opinions summarized above are subject to any new laws, rules and regulations or detailed implementations and interpretations in any form relating to the M&A Rules. We cannot assure you that relevant PRC government agencies, including the CSRC, would reach the same conclusion as our PRC legal counsel, and hence we may face regulatory actions or other sanctions from the CSRC or other PRC regulatory agencies. These regulatory agencies may impose fines and penalties on our operations in China, limit our ability to pay dividends outside of China, limit our operating privileges in China, delay or restrict the repatriation of the proceeds from this offering into China or take other actions that could have a material adverse effect on our business, financial condition, results of operations and prospects, as well as the trading price of the ADSs. The CSRC or other PRC regulatory agencies also may take actions requiring us, or making it advisable for us, to halt this offering before settlement and delivery of the ADSs offered hereby. Consequently, if you engage in market trading or other activities in anticipation of and prior to settlement and delivery, you do so at the risk that settlement and delivery may not occur. In addition, if the CSRC or other regulatory agencies later promulgate new rules or explanations requiring that we obtain their approvals for this offering, we may be unable to obtain a waiver of such approval requirements, if and when procedures are established to obtain such a waiver. Any uncertainties and/or negative publicity regarding such approval requirement could have a material adverse effect on the trading price of the ADSs.

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

        Upon completion of this offering, we will become a public company and expect to incur significant legal, accounting and other expenses that we did not incur as a private company. The Sarbanes-Oxley Act of 2002, as well as rules subsequently implemented by the SEC and the NASDAQ, impose various requirements on the corporate governance practices of public companies. As a company with less than US$1.07 billion in revenues for our last fiscal year, we qualify as an "emerging growth company" pursuant to the JOBS Act. An emerging growth company may take advantage of specified reduced reporting and other requirements that are otherwise applicable generally to public companies. These provisions include exemption from the auditor attestation requirement under Section 404 of the Sarbanes-Oxley Act of 2002, or Section 404, in the assessment of the emerging growth company's internal control over financial reporting. The JOBS Act also permits an emerging growth company to delay adopting new or revised accounting standards until such time as those standards apply to private companies. We have elected to take advantage of such exemptions. After we are no longer an

51

Table of Contents

"emerging growth company," we expect to incur significant expenses and devote substantial management effort toward ensuring compliance with the requirements of Section 404 and the other rules and regulations of the SEC.

        We expect the rules and regulations applicable to us after we becoming a public company to increase our legal and financial compliance costs and to make some corporate activities more time-consuming and costly. For example, as a result of becoming a public company, we will need to increase the number of independent directors and adopt policies regarding internal controls and disclosure controls and procedures. We also expect that operating as a public company will make it more difficult and more expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. In addition, we will incur additional costs associated with our public company reporting requirements. It may also be more difficult for us to find qualified persons to serve on our Board of Directors or as executive officers. We are currently evaluating and monitoring developments with respect to these rules and regulations, and we cannot predict or estimate with any degree of certainty the amount of additional costs we may incur or the timing of such costs.

We are a foreign private issuer within the meaning of the rules under the Exchange Act, and as such we are exempt from certain provisions applicable to U.S. domestic public companies.

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

•

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



•

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



•

the sections of the Exchange Act requiring insiders to file public reports of their stock ownership and trading activities and liability for insiders who profit from trades made in a short period of time; and



•

the selective disclosure rules by issuers of material nonpublic information under Regulation FD.

        We will be required to file an annual report on Form 20-F within four months of the end of each fiscal year. In addition, we intend to publish our results on a quarterly basis as press releases, distributed pursuant to the rules and regulations of the NASDAQ. Press releases relating to financial results and material events will also be furnished to the SEC on Form 6-K. However, the information we are required to file with or furnish to the SEC will be less extensive and less timely compared to that required to be filed with the SEC by U.S. domestic issuers. As a result, you may not be afforded the same protections or information that would be made available to you were you investing in a U.S. domestic issuer.

There can be no assurance that we will not be a passive foreign investment company, or PFIC, for our current or future taxable years, which could result in adverse U.S. federal income tax consequences to U.S. investors in our Shares.

        In general, a non-U.S. corporation is a PFIC for any taxable year in which (i) 75% or more of its gross income consists of passive income or (ii) 50% or more of the average quarterly value of its assets consists of assets that produce, or are held for the production of, passive income. For purposes of the above calculations, a non-U.S. corporation that owns at least 25% by value of the shares of another corporation is treated as if it held its proportionate share of the assets of the other corporation and received directly its proportionate share of the income of the other corporation. Passive income

52

---

Table of Contents

generally includes dividends, interest, rents, royalties and certain gains. Cash is a passive asset for these purposes. Goodwill is an active asset under the PFIC rules to the extent attributable to activities that produce active income.

        Based on the expected composition of our income and assets and the value of our assets, including goodwill, which is based on the expected price of the ADSs in this offering, we do not expect to be a PFIC for our current taxable year. However, it is not entirely clear how the contractual arrangements between us and our VIE will be treated for purposes of the PFIC rules, and we may be or become a PFIC if our VIE is not treated as owned by us. Because the treatment of our contractual arrangements with our VIE is not entirely clear, because we will hold a substantial amount of cash following this offering and because our PFIC status for any taxable year will depend on the composition of our income and assets and the value of our assets from time to time (which may be determined, in part, by reference to the market price of ADSs, which could be volatile), there can be no assurance that we will not be a PFIC for our current or any future taxable year.

        If we were a PFIC for any taxable year during which a U.S. investor owns our Shares, certain adverse U.S. federal income tax consequences could apply to such U.S. investor. See "Taxation—U.S. Federal Income Tax Consideration—Passive Foreign Investment Company Rules."

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

        The deposit agreement governing the ADSs representing our Class A ordinary shares provides that, to the fullest extent permitted by law, ADS holders waive the right to a jury trial of any claim they may have against us or the depositary arising out of or relating to our shares, the ADSs or the deposit agreement, including any claim under the U.S. federal securities laws.

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

        If you or any other holders or beneficial owners of ADSs bring a claim against us or the depositary in connection with matters arising under the deposit agreement or the ADSs, including claims under federal securities laws, you or such other holder or beneficial owner may not be entitled to a jury trial with respect to such claims, which may have the effect of limiting and discouraging lawsuits against us and/or the depositary. If a lawsuit is brought against us and/or the depositary under the deposit agreement, it may be heard only by a judge or justice of the applicable trial court, which would be conducted according to different civil procedures and may result in different outcomes than a trial by jury would have had, including results that could be less favorable to the plaintiff(s) in any such action.

        Nevertheless, if this jury trial waiver provision is not permitted by applicable law, an action could proceed under the terms of the deposit agreement with a jury trial. No condition, stipulation or provision of the deposit agreement or ADSs serves as a waiver by any holder or beneficial owner of ADSs or by us or the depositary of compliance with any substantive provision of the U.S. federal securities laws and the rules and regulations promulgated thereunder.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

        This prospectus contains forward-looking statements that involve risks and uncertainties. All statements other than statements of historical facts are forward-looking statements. These statements involve known and unknown risks, uncertainties and other factors that may cause our actual results, performance or achievements to be materially different from those expressed or implied by the forward-looking statements.

        You can identify these forward-looking statements by words or phrases such as "may," "will," "expect," "anticipate," "aim," "estimate," "intend," "plan," "believe," "likely to" or other similar expressions. We have based these forward-looking statements largely on our current expectations and projections about future events and financial trends that we believe may affect our financial condition, results of operations, business strategy and financial needs. These forward-looking statements include, but are not limited to, statements about:

•

our mission and growth strategies;



•

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



•

relevant government policies and regulations relating to our business and industry;



•

our expectation regarding the use of proceeds from this offering;



•

general economic and business condition in China; and



•

assumptions underlying or related to any of the foregoing.

        You should read thoroughly this prospectus and the documents that we refer to in this prospectus with the understanding that our actual future results may be materially different from and worse than what we expect. Other sections of this prospectus include additional factors which could adversely impact our business and financial performance. Moreover, we operate in an evolving environment. New risk factors and uncertainties emerge from time to time and it is not possible for our management to predict all risk factors and uncertainties, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. We qualify all of our forward-looking statements by these cautionary statements.

        You should not rely upon forward-looking statements as predictions of future events. We undertake no obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

        This prospectus also contains statistical data and estimates that we obtained from industry publications and reports generated by third-party providers of market intelligence. These industry publications and reports generally indicate that the information contained therein was obtained from sources believed to be reliable, but do not guarantee the accuracy and completeness of such information. Although we believe that the publications and reports are reliable, we have not independently verified the data.

USE OF PROCEEDS

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

        We plan to use the net proceeds of this offering for general corporate purposes, which may include store network expansion, customer acquisition, research and development, sales and marketing, investment in our technology infrastructure, working capital, and other general and administrative matters. In utilizing the proceeds from this offering, we are permitted under PRC laws and regulations to provide funding to our PRC subsidiaries only through loans or capital contributions, and to our consolidated VIE only through loans, and only if we satisfy the applicable government registration and approval requirements. We cannot assure you that we will be able to meet these requirements on a timely basis, if at all. See "Risk Factors—Risks Relating to Doing Business in China—PRC regulation of loans to and direct investment in PRC entities by offshore holding companies and governmental control of currency conversion may delay us from using the proceeds of this offering to make loans or additional capital contributions to our PRC subsidiaries, which could materially and adversely affect our liquidity and our ability to fund and expand our business." We expect that all the net proceeds from this offering will be used in the PRC in the form of RMB and mainly by funding our PRC subsidiaries through capital contributions. In general, the relevant registration and approval procedures for capital contributions typically take approximately eight weeks to complete and there is no statutory limit on the amount of capital contributions under PRC laws and regulations. We currently see no material obstacles in completing the registration and approval procedures with respect to future capital contributions to our PRC subsidiaries.

        Pending use of the net proceeds, we intend to hold our net proceeds in short-term, interest-bearing, financial instruments or demand deposits.

DIVIDEND POLICY

        We have not previously declared or paid cash dividends and we have no plan to declare or pay any dividends in the near future on our shares or the ADSs representing our Class A ordinary shares. We currently intend to retain most, if not all, of our available funds and any future earnings to operate and expand our business.

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

        Our Board of Directors has discretion as to whether to distribute dividends, subject to certain requirements of Cayman Islands law. In addition, our shareholders may by ordinary resolution declare a dividend, but no dividend may exceed the amount recommended by our Board of Directors. Under Cayman Islands law, a Cayman Islands company may pay a dividend out of either profit or share premium account, provided that in no circumstances may a dividend be paid if this would result in the company being unable to pay its debts as they fall due in the ordinary course of business. Even if our Board of Directors decides to pay dividends, the form, frequency and amount will depend upon our future operations and earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that the board of directors may deem relevant. If we pay any dividends on our ordinary shares, we will pay those dividends which are payable in respect of the Class A ordinary shares underlying the ADSs to the depositary, as the registered holder of such Class A ordinary shares, and the depositary then will pay such amounts to the ADS holders in proportion to the Class A ordinary shares underlying the ADSs held by such ADS holders, subject to the terms of the deposit agreement, including the fees and expenses payable thereunder. See "Description of American Depositary Shares."

CAPITALIZATION

        The following table sets forth our capitalization as of December 31, 2018:

•

on an actual basis;



•

on a pro forma basis to reflect the conversion of all of our company's ordinary shares, angel shares, Series A convertible redeemable preferred shares and Series B convertible redeemable preferred shares into 1,984,709 Class B ordinary shares upon completion of this offering; and



•

on a pro forma as adjusted basis to reflect (i) the conversion of all of our company's ordinary shares, angel-1 shares, angel-2 shares, Series A convertible redeemable preferred shares and Series B convertible redeemable preferred shares into 1,991,518 Class B ordinary shares upon completion of this offering, including 6,809 Series B convertible redeemable preferred shares issued on January 9, 2019, (ii) the recognization of a share-based compensation expense upon the satisfaction of the performance condition of this offering and (iii) the issuance and sale of                        Class A ordinary shares in the form of ADSs by us in this offering at an assumed initial public offering price of US$               per ADS being the mid-point of the estimated range of the initial offering price shown on the front cover of this prospectus, after deducting the underwriting discounts and commissions and estimated offering expenses payable by us (assuming the underwriters do not exercise their option to purchase additional ADSs).

Table of Contents

DILUTION

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

        Our net tangible book value as of December 31, 2018 was approximately US$            per ordinary share and US$            per ADS. Net tangible book value per ordinary share represents the amount of total tangible assets, minus the amount of total liabilities, divided by the total number of ordinary shares outstanding. Dilution is determined by subtracting net tangible book value per ordinary share from the public offering price per ordinary share.

        Without taking into account any other changes in such net tangible book value after December 31, 2018, other than to give effect to (i) the conversion of all of our angel shares and preferred shares into ordinary shares on a one-to-one basis, which will occur automatically immediately prior to completion of this offering and (ii) our issuance and sale of ADSs offered in this offering at an initial public offering price of US$            per ADS being the mid-point of the estimated range of the initial offering price shown on the front cover of this prospectus, after deduction of the underwriting discounts and commissions and estimated offering expenses payable by us, our pro forma as adjusted net tangible book value as of December 31, 2018 would have been approximately US$             million, or US$            per ordinary share and US$            per ADS, to existing shareholders and an immediate dilution in net tangible book value of US$            per ordinary share, or US$            per ADS, to purchasers of ADSs in this offering.

        The following table illustrates the dilution on a per ordinary share basis at the assumed initial public offering price per ordinary share is US$            and all ADSs are exchanged for ordinary shares:

        The pro forma information discussed above is illustrative only.

        The following table summarizes, on a pro forma basis as of December 31, 2018, the differences between the existing shareholders and the new investors with respect to the number of ordinary shares purchased from us in this offering, the total consideration paid and the average price per ordinary share paid at the initial public offering price of US$    per ADS before deducting estimated underwriting discounts and commissions and estimated offering expenses. The total number of ordinary

shares does not include ordinary shares underlying the ADSs issuable upon the exercise of the over-allotment option granted to the underwriters.

        The discussion and tables above also assume no exercise of any stock options outstanding as of the date of this prospectus. As of the date of this prospectus, there are 158,031 ordinary shares issuable upon exercise of outstanding stock options under the 2019 Share Option Plan. To the extent that any of these options are exercised, there will be further dilution to new investors.

EXCHANGE RATE INFORMATION

        Our reporting currency is the Renminbi because our business is mainly conducted in China and all of our revenues are denominated in Renminbi. This prospectus contains translations of Renminbi amounts into U.S. dollars at specific rates solely for the convenience of the reader. The conversion of Renminbi into U.S. dollars in this prospectus is based on the rate certified for customs purposes by the Federal Reserve Bank of New York. Unless otherwise noted, all translations from Renminbi to U.S. dollars and from U.S. dollars to Renminbi in this prospectus are made at RMB6.8755 to US$1.00, the exchange rate set forth in the H.10 statistical release of the Federal Reserve Board on December 31, 2018. We make no representation that any Renminbi or U.S. dollar amounts could have been, or could be, converted into U.S. dollars or Renminbi, as the case may be, at any particular rate, the rates stated below, or at all. The PRC government imposes control over its foreign currency reserves in part through direct regulation of the conversion of Renminbi into foreign exchange and through restrictions on foreign trade. On March 29, 2019, the rate was RMB6.7112 to US$1.00.

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

ENFORCEABILITY OF CIVIL LIABILITIES

        We were incorporated in the Cayman Islands in order to enjoy the following benefits:

•

political and economic stability;



•

an effective judicial system;



•

a favorable tax system;



•

the absence of exchange control or currency restrictions; and



•

the availability of professional and support services.

        However, certain disadvantages accompany incorporation in the Cayman Islands. These disadvantages include, but are not limited to, the following:

•

the Cayman Islands has a less developed body of securities laws as compared to the United States and may provide protection for investors to a lesser extent; and



•

Cayman Islands companies may not have standing to sue before the federal courts of the United States.

        Our constitutional documents do not contain provisions requiring that disputes, including those arising under the securities laws of the United States, between us, our officers, directors and shareholders, be arbitrated.

        All of our operations are conducted outside the United States, and all of our assets are located outside the United States. A majority of our directors and officers are nationals or residents of jurisdictions other than the United States and a substantial portion of their assets are located outside the United States. As a result, it may be difficult for a shareholder to effect service of process within the United States upon these persons, or to enforce against us or them judgments obtained in United States courts, including judgments predicated upon the civil liability provisions of the securities laws of the United States or any state in the United States.

        We have appointed            as our agent upon whom process may be served in any action brought against us under the securities laws of the United States.

        Conyers Dill & Pearman, our counsel as to Cayman Islands law, and King & Wood Mallesons, our counsel as to PRC law, have advised us, respectively, that there is uncertainty as to whether the courts of the Cayman Islands and China, respectively, would:

•

recognize or enforce judgments of United States courts obtained against us or our directors or officers predicated upon the civil liability provisions of the securities laws of the United States or any state in the United States; or



•

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

        We have been advised by Conyers Dill & Pearman, our counsel as to Cayman Islands laws, that the courts of the Cayman Islands would recognise as a valid judgment, a final and conclusive judgment in personam obtained in the federal or state courts in the United States under which a sum of money is payable (other than a sum of money payable in respect of multiple damages, taxes or other charges of a like nature or in respect of a fine or other penalty) or, in certain circumstances, an in personam judgment for non-monetary relief, and would give a judgment based thereon provided that (a) such courts had proper jurisdiction over the parties subject to such judgment, (b) such courts did not contravene the rules of natural justice of the Cayman Islands, (c) such judgment was not obtained by fraud, (d) the enforcement of the judgment would not be contrary to the public policy of the Cayman

Islands, (e) no new admissible evidence relevant to the action is submitted prior to the rendering of the judgment by the courts of the Cayman Islands, and (f) there is due compliance with the correct procedures under the laws of the Cayman Islands.

        We have been advised by King & Wood Mallesons, our PRC legal counsel, that there is uncertainty as to whether the courts of the PRC would enforce judgments of United States courts or Cayman courts obtained against us or these persons predicated upon the civil liability provisions of the United States federal and state securities laws. King & Wood Mallesons has further advised us that the recognition and enforcement of foreign judgments are provided for under PRC Civil Procedures Law. PRC courts may recognize and enforce foreign judgments in accordance with the requirements of PRC Civil Procedures Law based either on treaties between China and the country where the judgment is made or on reciprocity between jurisdictions. China does not have any treaties or other form of reciprocity with the United States or the Cayman Islands that provide for the reciprocal recognition and enforcement of foreign judgments. In addition, according to the PRC Civil Procedures Law, courts in the PRC will not enforce a foreign judgment against us or our directors and officers if they decide that the judgment violates the basic principles of PRC law or national sovereignty, security or public interest. As a result, it is uncertain whether and on what basis a PRC court would enforce a judgment rendered by a court in the United States or in the Cayman Islands.

CORPORATE HISTORY AND STRUCTURE

Corporate History

        In June 2017, we incorporated Lucky Coffee Inc. under the laws of the Cayman Islands as our offshore holding company, which later changed its name to Luckin Coffee Inc. in September 2017.

exercise effective control over our VIE;



•

receive substantially all of the economic benefits of our VIE; and

have an exclusive option to purchase all or part of the equity interest in and/or assets of our VIE when and to the extent permitted by laws.

Table of Contents

        As a result of these contractual arrangements, we are the primary beneficiary of the VIE and, therefore, have consolidated the financial results of the VIE in our consolidated financial statements in accordance with U.S. GAAP.

        In the opinion of King & Wood Mallesons, our PRC counsel:

•

the ownership structure of the VIE, currently and immediately after completion of his offering, are not in violation of applicable PRC laws and regulations currently in effect; and



•

the contractual arrangements among the Beijing WFOE, the VIE and the shareholders of the VIE, governed by PRC law, currently and immediately after giving effect to this offering, are legal, valid, binding and enforceable in accordance with its terms and applicable PRC Laws.

        However, our PRC legal counsel has also advised us that there are substantial uncertainties regarding the interpretation and application of current and future PRC laws, regulations and rules. Accordingly, the PRC regulatory authorities may take a view that is contrary to the opinion of our PRC legal counsel.

        The following is a summary of the contractual arrangements by and among the Beijing WFOE, the VIE and the shareholders of the VIE and their spouses, as applicable.

Each of the shareholders of the VIE further confirmed that they will unwind the contractual agreements and transfer all of the shares of the VIE to Beijing WFOE or any party designated by Beijing WFOE as soon as the applicable laws of the PRC allow Beijing WFOE to operate the business operated by the VIE without the contractual agreements, and will return any consideration received through this to Beijing WFOE or any party designated by Beijing WFOE.

Beijing WFOE will have the exclusive ownership of all intellectual property rights developed by performance of this agreement.

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

        You should read the following discussion and analysis of our financial condition and results of operations in conjunction with the section entitled "Selected Consolidated Financial Data" and our consolidated financial statements and the related notes included elsewhere in this prospectus. This discussion contains forward-looking statements that involve risks and uncertainties. Our actual results and the timing of events could differ materially from those anticipated in these forward-looking statements as a result of various factors, including those set forth under "Risk Factors" and elsewhere in this prospectus.

Overview

        We are China's second largest and fastest-growing coffee network, in terms of number of stores and cups of coffee sold, according to the Frost & Sullivan Report. We have pioneered a technology-driven new retail model to provide coffee and other products with high quality, high affordability and high convenience to our customers. We believe that our disruptive model has fulfilled the large unmet demand for coffee and driven its mass market consumption in China, while allowing us to achieve significant scale and growth since our inception.

        Driven by technology, our new retail model is built upon our mobile apps and store network. Our mobile apps cover the entire customer purchase process, offering our customers a 100% cashier-less environment. This enhances our customer experience, improves our operating efficiency, and allows us to stay connected with our customers and engage them anytime, anywhere. While operating three types of stores, we strategically focus on pick-up stores, which accounted for 91.3% of our total stores as of March 31, 2019. Our pick-up stores have limited seating and are typically located in areas with high demand for coffee, such as office buildings, commercial areas and university campuses. This enables us to stay close to our target customers and expand rapidly with low rental and decoration costs. Our focus on technologies has enabled us to operate efficiently, grow rapidly while maintaining quality control.

        We offer premium coffee and other high-quality products to our customers. We source premium Arabica coffee beans from prominent suppliers and engage World Barista Champion teams to design our coffee recipes. We procure coffee machines and coffee condiments from renowned global suppliers such as Schaerer. We also partner with reputable suppliers for our other products such as juices and light meals. Due to our scale, we are able to procure high-quality products from our suppliers at favorable prices.

        Since inception, we have successfully built a brand of distinguished value propositions—high quality, high affordability and high convenience. We have also been able to cultivate a large and loyal customer base and achieve strong growth. Within 18 months, we expanded from a single trial store in Beijing to 2,370 stores in 28 cities in China as of March 31, 2019. We had over 16.8 million of cumulative transacting customers as of March 31, 2019. In addition, our customer repurchase rate in 2018 was over 54%.

        China's freshly brewed coffee market is highly underpenetrated due to inconsistent qualities, high prices and inconvenience. We believe that our model has successfully driven the mass market coffee consumption in China by addressing these three pain points. We aim to become the largest coffee network in China, in terms of number of stores, by the end of 2019.

Key Operating Data

        We regularly monitor a number of operating metrics in order to measure our current performance and project our future performance. These metrics aid us in developing and refining our growth strategies and making strategic decisions.

        The following chart presents our new customer acquisition costs for the periods indicated:

72

---

Table of Contents

---

(1)

Free product promotion expenses per new transacting customer are calculated as total free product promotion expenses incurred during a specific period divided by the number of new transacting customers during the period.

(2)

New customer acquisition costs are calculated as the sum of advertising expenses, free product promotion expenses and other sales and marketing expenses incurred during a specific period divided by the number of new transacting customers during the period.

        New customer acquisition costs decreased from RMB103.5 in the first quarter of 2018 to RMB25.0 in the fourth quarter of 2018 per new transacting customer. The significant decrease in new customer acquisition costs was primarily attributable to our established brand, effective user engagement via our Luckin mobile app, and our expansive network. Specifically, we are able to generate valuable user traffic through our Luckin mobile app, and in 2018, 91.3% of new customers made their first purchase via our Luckin mobile app.

        The following chart presents our customer retention rate for the periods indicated:

---

(1)

We refer to new transacting customers during a specific month as a cohort. Customer retention rate of a cohort in a specific month is calculated as the number of transacting customers from the cohort during the month divided by the total number of customers from the cohort.

        Customer retention rate demonstrates our customer loyalty. Despite a limited operating history, we have observed a typical customer behavior pattern. As illustrated in the chart above, customer retention rate tends to drop in the second month for most cohorts as many customers are initially attracted to our platform by our free vouchers. Customer retention rate tends to gradually increase in the following months as a result of the expansion of our store network, growing brand awareness, more diversified product offerings and enhanced customer experience. However, as our stores are mainly located in office buildings and our products are mostly consumed in office settings, we generally experience a seasonal decrease in customer retention rate during the Chinese New Year holidays.

General Factors Affecting Our Results of Operations

        Our business and results of operations are affected by a number of general factors in China, including:

•

China's overall economic growth, level of urbanization and level of per capita disposable income;



•

Growth in consumer expenditure, especially the expenditure on food and beverage;



•

Consumers' demand for coffee, especially for freshly brewed coffee; and



•

Increasing usage of mobile internet and increasing adoption of mobile payment.

        Unfavorable changes in any of these general factors could materially and adversely affect our business and results of operations.

Specific Factors Affecting Our Results of Operations

Our ability to attract and engage customers

        Our revenue growth is mainly driven by our ability to attract new customers and actively engage existing customers. Driven by technology, our new retail model is built upon our mobile apps and store network, which allows us to stay close to our customers and engage them anytime, anywhere. We leverage big data analytics and Al to analyze our customer behavior and transaction data, which enables us to attract new customers and retain and engage existing customers to increase repurchases. As of March 31, 2019, we had over 16.8 million cumulative transacting customers, and our repurchase rate was over 54% in 2018.

Increase product offerings and cross-sell

        While focusing on providing high-quality coffee items, we have also enriched our product offerings by introducing a selective number of new products to meet our target customers' daily needs. We will continue to accumulate data insights on customer behavior to introduce new products. We believe that selectively diversifying our product offerings will increase customer repurchases and revenue per customer. ln 2018, we sold close to 90 million coffee and other product items, among which, 30.9% were non-coffee products.

The expansion of our store network

        The scale of our store network affects our business and revenue growth. We started our business in October 2017 and within 18 months, we became the second largest coffee network in China, in terms of number of stores, as of December 31, 2018. Our stores are 100% self-owned, all of which are located

74

in the economically vibrant regions in China. The following table sets out the total number of our stores and their movement since our inception.

        Our scale, supported by technologies, enables us to gain more bargaining power over our suppliers and lower our operating cost as a percentage of our revenue. Our expanding presence in the market will also enhance our brand image, which we believe will further reduce our customer acquisition costs. We believe that our new retail model can help create a virtuous cycle which reinforces our leadership position. With more stores, we can serve more customers, accumulate more data, and achieve higher operational efficiency.

Effective selling prices of our products

        We have adopted a dynamic pricing model where we use algorithms to adjust and apply different discounts to our customers with different consumption preferences in the form of coupons and discount vouchers. The effective selling prices of our products represent our retail prices after applying such discounts. We take into account a number of factors, including costs of materials and customer demand when determining our effective selling prices. Our future profitability will be affected by our ability to properly manage the effective selling prices of our products.

Efficient store operations

        We pursue and achieve store operational efficiency by leveraging technology. With our strong data analytics capabilities and smart supply chain management system, we are able to analyze sales and inventory status for each store on a real-time basis and efficiently replenish inventory. Big data analytics also help us manage our overall workforce and enable us to maintain efficient storefront operations.

        Our technology-driven new retail business model significantly improves our operational efficiency. We measure our store performance with store level operating profit (loss), which is calculated by deducting cost of materials, store rental and other operating costs and depreciation expenses from net revenues. Our store level operating loss was RMB374.5 million (US$54.5 million) and RMB3.0 million in 2018 and for the period from June 16, 2017 (inception date) to December 31, 2017, respectively. The store level operating loss accounted for 44.5% and 1,206.0% of net revenues in 2018 and for the period from June 16, 2017 (inception date) to December 31, 2017, respectively. ln the long run, we expect our store level operating costs, including cost of materials, store rental and other operating costs and depreciation expenses, will continue to decrease as percentage of our net revenues.

Seasonality

        We experience seasonality in our business, primarily as a result of orders fluctuations in holiday seasons. For example, we generally experience fewer purchase orders during Chinese New Year holidays which fall between late January and late February. The decrease of sales during the holiday seasons is a typical pattern in the coffee market. For risks related to the seasonality of our business, see

        Depreciation expenses.    Depreciation expenses consist primarily of depreciation charges for our machines and equipment and depreciation expenses for leasehold improvements.

        Sales and marketing expenses.    Sales and marketing expenses consist primarily of advertising expenses, cost of free products we offer to customers as part of our marketing initiative to attract new customers, delivery expenses as well as payroll expenses for sales and marketing employees.

        General and administrative expenses.    General and administrative expenses consist primarily of payroll and other employee benefits for our administrative employees, research and development expenses, rental expenses for our office buildings and other office expenses.

        Store preopening and other expenses.    Before opening new stores, it usually takes us sometime to decorate the new stores and make preparation for store opening. Store preopening expenses primarily include rental costs incurred before opening of new stores. Other expenses mainly include lease exit costs.

Taxation

Cayman Islands

        We are incorporated in the Cayman Islands. Under the current law of the Cayman Islands, we are not subject to income or capital gains tax. In addition, dividend payments are not subject to withholding tax in the Cayman Islands.

British Virgin Islands

        Our subsidiary incorporated in the British Virgin Islands is not subject to income or capital gains tax under the current laws of the British Virgin Islands. The British Virgin Islands do not impose a withholding tax on dividends.

Hong Kong

        Our subsidiary incorporated in Hong Kong is subject to Hong Kong profit tax at a rate of 16.5%. No Hong Kong profit tax has been levied as we did not have assessable profit that was earned in or derived from the Hong Kong subsidiary during the periods presented. Hong Kong does not impose a withholding tax on dividends.

PRC

        Our subsidiaries incorporated in China and our VIE are subject to PRC enterprise income tax on their taxable income in accordance with the relevant PRC income tax laws. Pursuant to the PRC Enterprise Income Tax Law, or the EIT Law, which became effective on January 1, 2008, a uniform 25% enterprise income tax rate is generally applicable to both foreign-invested enterprises and domestic enterprises, except where a special preferential rate applies. For example, enterprises qualified as "High and New Technology Enterprises" are entitled to a 15% enterprise income tax rate rather than the 25% uniform statutory tax rate. The enterprise income tax is calculated based on the entity's global income as determined under PRC tax laws and accounting standards.

        Our PRC subsidiaries are subject to value-added taxes, or VAT, at a rate from 6% to 16% on our products and services, less any deductible VAT we have already paid or borne. They are also subject to surcharges on VAT payments in accordance with PRC law. As a Cayman Islands holding company, we

77

Table of Contents

may receive dividends from our PRC subsidiaries. The PRC EIT Law and its implementing rules provide that dividends paid by a PRC entity to a nonresident enterprise for income tax purposes is subject to PRC withholding tax at a rate of 10%, subject to reduction by an applicable tax treaty with China. Pursuant to the Arrangement between Mainland China and the Hong Kong Special Administrative Region for the Avoidance of Double Taxation and Tax Evasion on Income, the withholding tax rate in respect to the payment of dividends by a PRC enterprise to a Hong Kong enterprise may be reduced to 5% from a standard rate of 10% if the Hong Kong enterprise directly holds at least 25% of the PRC enterprise. Pursuant to the Notice of the State Administration of Taxation on the Issues concerning the Application of the Dividend Clauses of Tax Agreements, or SAT Circular 81, a Hong Kong resident enterprise must meet the following conditions, among others, in order to apply the reduced withholding tax rate: (i) it must be a company; (ii) it must directly own the required percentage of equity interests and voting rights in the PRC resident enterprise; and (iii) it must have directly owned such required percentage in the PRC resident enterprise throughout the 12 months prior to receiving the dividends. In August 2015, the State Administration of Taxation promulgated the Administrative Measures for Nonresident Taxpayers to Enjoy Treatment under Tax Treaties, or SAT Circular 60, which became effective on November 1, 2015. SAT Circular 60 provides that nonresident enterprises are not required to obtain preapproval from the relevant tax authority in order to enjoy the reduced withholding tax. Instead, nonresident enterprises and their withholding agents may, by self-assessment and on confirmation that the prescribed criteria to enjoy the tax treaty benefits are met, directly apply the reduced withholding tax rate, and file necessary forms and supporting documents when performing tax filings, which will be subject to post-tax filing examinations by the relevant tax authorities. Accordingly, we may be able to benefit from the 5% withholding tax rate for the dividends received from PRC subsidiaries if it satisfies the conditions prescribed under SAT Circular 81 and other relevant tax rules and regulations. However, according to SAT Circular 81 and SAT Circular 60, if the relevant tax authorities consider the transactions or arrangements we have are for the primary purpose of enjoying a favorable tax treatment, the relevant tax authorities may adjust the favorable withholding tax in the future.

        If our holding company in the Cayman Islands or any of our subsidiaries outside of China were deemed to be a "resident enterprise" under the PRC EIT Law, it would be subject to enterprise income tax on its worldwide income at a rate of 25%. See "Risk Factors—Risks Relating to Doing Business in China—If we are classified as a PRC resident enterprise for PRC enterprise income tax purposes, such classification could result in unfavorable tax consequences to us and our non-PRC shareholders and the ADS holders."

Net Revenues

        Our net revenues were RMB840.7 million (US$122.3 million) in 2018 and RMB0.3 million for the period from June 16, 2017 (inception date) to December 31, 2017. The growth of our net revenues was primarily driven by the significant increases in the number of our transacting customers, our stores and our products sold. As of December 31, 2018, we had over 12.5 million transacting customers, and in 2018, we sold close to 90 million coffee and other product items. As of December 31, 2018, we operated 2,073 stores in China.

Freshly brewed drinks

        Our net revenues from freshly brewed drinks was RMB649.6 million (US$94.5 million), representing 77.3% of total net revenues in 2018 and RMB0.2 million, representing 86.0% of total net revenues for the period from June 16, 2017 (inception date) to December 31, 2017. The growth of our freshly brewed drinks revenue was primarily driven by the significant increase in the number of our freshly brewed drinks sold. In 2018, we sold over 71.5 million freshly brewed drinks.

Other products

        Our net revenues from other products was RMB135.6 million (US$19.7 million), representing 16.1% of total net revenues in 2018 and RMB0.03 million, representing 10.0% of total net revenues for the period from June 16, 2017 (inception date) to December 31, 2017. The increase in proportion of other product revenue was primarily driven by the increase in sales of food and beverage items launched in 2018.

Others
