RISK FACTORS

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

Risks Relating to our Business and Industry

We have a limited operating history and our historical operating and financial results may not be indicative of future performance, which makes it difficult to predict our future business prospects and financial performance.

        Since e-vapor products were only introduced to the market in the last two decades, we operate in an innovative and rapidly evolving industry. We commenced our operation in January 2018 and thus have a limited operating history, which makes it difficult to evaluate our future prospects and performance.

        We cannot assure you that we can successfully implement our business model. As the market and our business develop, we may modify our products and services. These changes may not lead to expected results and may have a material and adverse impact on our results of operations and financial condition. Although our revenues have grown rapidly since our inception, due to our limited operating history, our past revenues and historical growth rate may not be indicative of our future performance. Our net revenues increased from RMB132.6 million for the 2018 period to RMB1,549.4 million (US$228.2 million) for the year ended December 31, 2019, and from RMB1,138.9 million for the nine months ended September 30, 2019 to RMB2,201.3 million (US$324.2 million) for the nine months ended September 30, 2020. We recorded net loss of RMB0.3 million for the 2018 period and generated net income of RMB47.7 million (US$7.0 million) for the year ended December 31, 2019. Our net income grew from RMB98.0 million for the nine months ended September 30, 2019 to RMB108.6 million (US$16.0 million) for the nine months ended September 30, 2020. We cannot assure you that we will be able to achieve similar results, maintain the ability to generate net profit or maintain profitability at similar level, or grow at the same rate as we did in the past or at all. Our ability to maintain profitability will depend primarily on our ability to generate sufficient revenues and to manage our costs of revenues and operating expenses. Rather than relying on our historical operating and financial results to evaluate us, you should consider our business prospects in light of the risks and difficulties we may encounter as an early-stage company operating in a new market, including, among other things, our ability to adapt to evolving regulatory landscape, develop and utilize our technologies, provide high-quality products and services, meet users' expectation, maintain and enhance our brand and reputation, improve our operational efficiency, and anticipate and adapt to changing market conditions. We may not be able to successfully address these risks and difficulties, which could significantly harm our business, results of operations and financial condition.

Changes in existing laws, regulations and policies and the issuance of new laws, regulations, policies and any other entry barriers in relation to the e-vapor industry have materially and adversely affected and may further materially and adversely affect our business operations.

        As e-vapor products have become more and more popular in recent years, government authorities in China may impose more stringent laws, regulations and policies to regulate such products and the e-vapor industry.

        Some countries have prohibited the usage of e-vapor products in certain areas or imposed specific taxes on e-vapor products. In China, there are currently no clear and specific national laws, regulations, rules or standards for the sale of e-cigarettes, including e-vapor products, save for the announcements

17

Table of Contents

regarding prohibition on the sale of e-cigarettes to the underage as well as online advertisement and sale through the internet. On August 28, 2018, the State Administration for Market Regulation and the State Tobacco Monopoly Administration jointly issued Announcement on Prohibition of Selling E-Cigarettes Products to the Underage, or the August 2018 Announcement, which specifically prohibits all sales of e-cigarettes to the underage. On October 30, 2019, the State Administration for Market Regulation and the State Tobacco Monopoly Administration jointly issued the Announcement on Further Protecting the Underage from E-Cigarettes, or the October 2019 Announcement, to further strengthen the protection of the physical and mental health of the underage and prevent the underage from buying e-cigarettes through the internet and using them. The October 2019 Announcement urged (i) e-cigarette producers and sellers to shut down their online sales websites or online sales application programs and to withdraw the advertisements published on the internet; and (ii) e-commerce platform operators to close e-cigarette online shops and take e-cigarettes off shelves. We sold some of our products online prior to the issuance of the October 2019 Announcement, and we took necessary measures to adjust our business to follow the October 2019 Announcement, including but not limited to the ceasing of online operations and online marketing activities and rigorously implementing underage usage prevention initiatives. As a result of the October 2019 Announcement and our adjustment measures, revenues generated from sales to users through third-party e-commerce platforms and sales to third-party e-commerce platform distributors decreased significantly to nominal, and we do not expect to generate revenues from selling e-vapor products through these distribution channels going forward.

        The August 2018 Announcement and the October 2019 Announcement, as well as any laws, regulations or governmental announcements that regulate the sale and use of e-cigarettes, may continue to adversely affect our business, growth and prospects. For example, the Notice of Maintaining Civil Aviation Order to Ensure Air Transportation Security promulgated by Civil Aviation Administration of China states that the usage of e-cigarettes would be treated as smoking and is therefore prohibited in aircrafts. In addition, some cities, such as Shenzhen, Hangzhou, Chengdu, Xi'an and Nanning, have banned the use of e-cigarettes in public places, which include, among others, public transportation and indoor workspace. Such prohibition may also affect the usage of our products, which may in turn adversely affect the sales of our products. Further, sales of e-cigarettes in China are also subject to relevant PRC laws and regulations that are generally applicable to the sales of goods, such as the Contract Law of the PRC and the Product Quality Law of the PRC. See "Regulation—Regulations Related to Our Products."

        In addition, certain articles published on Bulletin of the WHO stated that governments should consider prohibiting the use of e-vapor products in indoor areas to protect non-users from involuntary exposure to second-hand aerosols, issuing warnings about the potential health risks of e-vapor products and imposing higher taxes on e-vapor products. Certain limitations may be imposed on the e-vapor industry, such as prohibition of usage in public spaces or imposition of additional tax, either of which may materially and adversely affect the development of the e-vapor industry.

        We cannot assure you that government authorities will not impose further restrictions on e-vapor products in the future, including but not limited to requirements to obtain and maintain licenses, approvals or permits for relevant business operation. Such restrictions, if any, may adversely affect supplies of raw materials, production and sales activities, taxation or other aspects of our business operation. We may not be able to comply with any or all changes in existing laws and regulations or any new laws and regulations and may incur significant compliance cost. It is uncertain how government authorities in China will regulate e-vapor products or harm-reduction products in general and what additional regulations we may be subject to. All of the above may affect our production or market demand for e-vapor products, and thus adversely affect our business, financial condition and results of operations. As we continue to grow in scale and significance, we expect to face increased scrutiny, which may result in increased investment in compliance and related capabilities.

If it is determined or perceived that the usage of e-vapor products poses long-term health risks, the use of e-vapor products may decline significantly, which may materially and adversely affect our business, financial condition and results of operations.

        Since e-vapor products were only introduced to the market in the last two decades and are rapidly evolving, studies relating to the long-term health effects of e-vapor product usage are still ongoing. Currently, there remain uncertainties regarding whether e-vapor products are sufficiently safe for their intended use and health risks associated with the usage of e-vapor products have been under scrutiny. According to the WHO, there is no conclusive evidence that the use of e-vapor products facilitates smoking cessation. The WHO recommended governments to strengthen relevant laws and regulations on the sale of e-vapor products, to, among others, prohibit marketing strategies targeting the underage and the non-smoking population.

        Negative publicity on the health consequences of e-vapor products or other similar devices may also adversely affect the usage of e-vapor products. For example, the United States Food and Drug Administration, or the FDA, and the United States Centers for Disease Control and Prevention, or the CDC, issued a joint statement on August 30, 2019 linking a number of cases of respiratory illnesses to e-vapor product use. On November 8, 2019, the CDC announced that it had preliminarily linked cases of severe respiratory illness to the presence of Vitamin E acetate, which was found in certain Tetrahydrocannabinol (THC)-containing e-vapor cartridges for non-electronic nicotine delivery systems (non-ENDS) e-vapor products that may have been obtained illegally. However, evidence is not sufficient to rule out the contribution of other chemicals of concern, including chemicals in either THC or non-THC products. In January 2020, after further research, the FDA and CDC recommended against the use of THC-containing e-vapor products, especially those from unofficial sources, and that the underage, pregnant women and adults who do not currently use tobacco products should not start using e-vapor products. On February 25, 2020, the CDC issued a final update, stating that the number of cases of severe respiratory illnesses had declined to single digits as of February 9, 2020. The CDC also reconfirmed that (i) Vitamin E acetate, which was found in some THC-containing e-vapor cartridges for non-ENDS e-vapor products that were mostly obtained illegally, was strongly linked to and indicated to be the primary cause of the severe respiratory illnesses, and (ii) THC-containing e-vapor products from informal sources were linked to most cases of severe respiratory illnesses. Furthermore, there have been recent claims that users of e-vapor products may suffer a greater risk of more serious COVID-19 complications. However, it remained unclear whether the exposure to toxic chemicals through e-vapor product usage will increase the risk of COVID-19.

        Research regarding the actual causes of these illnesses is still ongoing. If e-vapor product usage is determined or perceived to pose long-term health risks or to be linked to illnesses, the usage of e-vapor products may significantly decline, which would have a material adverse effect on our business, financial condition and results of operations. Although we currently do not offer products containing THC, any perceived correlation between THC and Vitamin E acetate may adversely affect the public's perception of e-vapor products in general, regardless whether such products contain THC and/or Vitamin E.

We operate in an emerging and evolving market in China, which may develop more slowly or differently than we expect.

        The e-vapor market in China has experienced rapid growth in recent years. According to the CIC Report, the China's e-vapor market by retail sales value grew from US$0.6 billion in 2016 to US$1.5 billion in 2019. However, the growth rate may decrease due to uncertainties with respect to the acceptance of e-vapor technologies and products, health studies relating to e-vapor product use, China's macro-economy, disposable income growth, and pace of development of technologies and other factors. Furthermore, the e-vapor market in China is at its early stage and continues to evolve, and the penetration of e-vapor products among China's adult smokers remains relatively low. There can be no assurance that the penetration of e-vapor products among China's adult smokers will further deepen, or

19

Table of Contents

that the e-vapor market will grow at a pace that we expect. Additionally, China's e-vapor market development is subject to the uncertainty of China's overall regulatory landscape for such products, which may have a material impact on the market development of China's e-vapor products. There can be no assurance that the regulatory regime will be favorable to e-vapor products in general and us. It is also uncertain whether our products and services will achieve and sustain high levels of market acceptance and meet users' expectation. Our ability to increase the sales of our e-vapor products depends on several factors, some of which may be beyond our control, including users' receptiveness towards and adoption of e-vapor technologies and products, market awareness of our brand, the market acceptance of our products and services, the "word-of-mouth" effects of our products and services, our ability to attract, retain and effectively train customer representatives, our ability to develop effective relationships with distributors and expand our distribution and retail networks and the cost, performance and functionality of our products and services. If we are unsuccessful in implementing our business strategies, developing our e-vapor products or reaching adult smokers, or if these users do not accept our e-vapor products, the market for our products may not continue to develop or may develop more slowly than we expect, any of which could materially and adversely affect our profitability and growth prospects.

We are exposed to product liabilities and user complaints arising from the products we sell, which could have a material adverse impact on us.

        Currently, we primarily sell our products to our offline distributors, who then supply our products to retail outlets across China. Even when we are not selling our products directly to users, we may nevertheless be liable for defects in our products pursuant to general laws on product liabilities. We are exposed to potential product liability claims from users of our products in the event that the use of our products results in any personal injury, property damage or health and safety issues.

        There is no assurance that we can succeed in defending ourselves, and we may be required to pay significant amounts of damages for product liability claims. Further, product liability claims against us, whether or not successful, are costly and time-consuming to defend. These disputes may result in negative publicity that could severely damage our reputation and affect the marketability of our products, and could result in substantial costs and diversion of our resources and management's attention. Any of the above could in turn materially and adversely affect our business, financial condition and results of operations. Although we may seek indemnification or contribution from our suppliers in certain circumstances, we cannot assure you that we will be able to receive indemnification or contribution in full, or at all.

        Although we may have legal recourse against the suppliers and manufacturers of such products pursuant to applicable laws, attempts to enforce our rights against such suppliers and manufacturers may be expensive, time-consuming and not successful. We maintain limited product liability insurance for claims of personal injury and property damage caused by our products. There is no assurance that our insurance coverage will be adequate to cover such claims. Our insurance does not provide coverage for all liabilities (including liability for certain events involving pollution or other environmental claims). In addition, there can be no assurance that we will be able to maintain our product liability insurance on acceptable terms. If we cannot maintain our product liability insurance on reasonable terms or our insurance does not sufficiently compensate us for the losses we sustain in the event of a legal proceeding, our business, financial condition and results of operations would be adversely affected.

        We have received complaints in the past in relation to the quality and functionality of our products. We take these complaints seriously and endeavor to resolve such complaints by implementing various remedial measures. Nevertheless, we cannot assure you that we can successfully prevent or address all user complaints. We may also be subject to claims resulting from such complaints. Any complaints or claims against us, even if meritless and unsuccessful, may divert our management's attention and other resources from our business and adversely affect our business and 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 the quality, functionality and health concerns of e-vapor products, whether or not accurate, and whether or not concerning our products, can adversely affect our business, results of operations and reputation. Such negative publicity may reduce users' confidence in us, our products and our brand, which may adversely affect our business and results of operations.

Our business and results of operations may be harmed by any failure to maintain and enhance the value of our brand.

        As we primarily leverage word-of-mouth referrals among adult smokers to promote our brand, market recognition of our brand is critical for us to remain competitive. According to a survey conducted in September 2020 by CIC, we ranked 1st in terms of brand awareness, as evidenced by a mindshare of 67.6% among users of e-vapor products in China. However, we may not be able to maintain the reputation of our brand in the future.

        Our brand's recognition and reputation depend on our ability to consistently practice our ethical principles. For example, usage of our products by the underage would significantly impair our brand image. In addition, counterfeit products would also impair our brand image and cause disruption to our business. We have undertaken a number of key initiatives to address underage usage of our products and the issue of counterfeiting. We cannot assure you that these initiatives will be successful. For example, if we fail to implement effective measures to prevent purchases and uses of our products by the underage in accordance with announcements, guidance and regulations issued by government authorities, we may be subject to negative publicity and legal proceedings. Additionally, counterfeit products associated with our brand may also impair our brand image and cause disruption to our business. Counterfeit products may use logos and designs similar to ours in order to confuse the users. Our prospective or existing users may mistakenly use those counterfeit products and attribute any issues, dissatisfaction or frustration they experience from such products to our company, which may significantly impair our brand image. Even though we have devoted significant resources to combat sales of counterfeit products, there can be no guarantee that we may succeed in eliminating counterfeit products and it could take even greater efforts to eliminate the negative public perception of our company caused by such counterfeit products. If we fail to address the risks and challenges above, public perception of our brand may be materially and adversely affected.

        There have been cases of unauthorized distribution of our products and such distributors may continue to distribute our products without our authorization, violating our distribution and retail standards. As those unauthorized distributions are beyond our control, there can be no assurance that we can detect such unauthorized distribution in a timely manner or at all. Our brand image may be materially and adversely affected if such unauthorized distributions lead to negative public perception.

        In order to maintain and enhance the value of our brand, we also have to continue to provide a superior user experience and a wide selection of products, cater to users' preferences and expectations, and maintain the reliability, quality and functionality of our products, which in turn may also help us maintain our existing user base or have more new users. However, there can be no assurance that the user experience we provide through our products will be recognized or accepted by adult smokers in China. Failure to address these risks and challenges may materially and adversely affect our business, results of operations, financial condition and prospects.

        In addition, users may be discouraged from purchasing our products if there is any negative publicity in connection with the use of our products, such as the quality or side effects of our products. Our reputation may also be adversely affected if there are any negative publicity relating to us, our directors, officers, employees, distributors, retailers, suppliers and manufacturers that are known to associate with us. Negative publicity may concern various matters, including but not limited to failure to

21

Table of Contents

provide equal opportunities to our employees, inability to enforce our codes of ethics and business conducts and workplace sexual harassment. Furthermore, negative publicity about other market players or isolated incidents, regardless of whether or not it is factually correct or whether we have engaged in any inappropriate activities, may result in negative perception of our industry as a whole and undermine the credibility we have established. Any damage to our brand name or reputation as a result of these or other factors may cause our products and services to be perceived unfavorably by users, distributors, retailers, other business partners and governmental authorities, and our business operations and prospects could be materially and adversely affected as a result.

We rely on our offline distribution and retail network to supply our products to retail outlets and users in China. If they fail to supply our products in a satisfactory manner or comply with applicable laws, regulations and policies, our brand, business, results of operations and prospects may be materially and adversely affected.

        Our offline distribution and retail network plays a crucial role in bringing our products to adult smokers. We primarily sell our products to our distributors, who then supply the products to retail outlets and users in China. As of September 30, 2020, we partnered with 110 authorized distributors to supply our products to over 5,000 RELX Branded Partner Stores and over 100,000 retail outlets nationwide, covering over 250 cities in China. There can be no assurance that we will be able to maintain our existing relationships with distributors, RELX Branded Partner Stores and other retail outlets. We may have disputes with our distributors and retailers and there can be no assurance that such disputes could be resolved in a timely or cost-effective manner, or at all. If we fail to address such risks, our results of operations, financial condition and our reputation may be materially and adversely affected. Additionally, our existing distributors, branded stores and retail outlets may not be able to maintain or increase their sales or expand their sales. Moreover, as we expand into new geographic regions in China, we may fail to establish and maintain arrangements with new distributors, branded stores and other retail outlets in the regions on favorable terms or at all. In general, we may experience attrition in our distribution partners, branded stores and other retail outlets due to a number of factors, such as dissatisfactory operational performance, sales of our competitors' products, insufficient funding, business closures and unsuccessful contract renewal negotiations. In addition, we proactively manage our distribution partners, branded stores and other retail outlets and initiate account closures for various reasons, such as contract breaches by such distribution partners, branded stores and other retail stores. We cannot predict the level of attrition that may occur in the future. Higher than expected attrition could adversely affect our business, results of operations and financial condition.

        Any lack of requisite approvals, licenses or permits applicable to our distributors and retailers may have a material and adverse impact on our business. In accordance with the relevant laws and regulations, our distributors may be required to maintain various approvals, licenses and permits to operate their business, including but not limited to business license. There can be no assurance that our distributors and retailers can maintain their requisite approvals, licenses or permits applicable to their business at all times or obtain such approvals, licenses or permits. In the event that they are not in compliance with such approvals, licenses or permits requirements, there can be no guarantee that they will rectify such incompliance in a timely manner or at all, which may adversely affect the distribution and sales of our products. As a result, our business, results of operations and financial condition may be materially and adversely affected.

        Although we closely monitor and manage our distributors, RELX Branded Partner Stores and other retail outlets, there can be no assurance that we will be successful in detecting and correcting noncompliance with applicable laws, breach of the distribution agreements with us or any inconsistencies between their practice and our brand image or values, in a timely and effective manner or at all. Any misconduct or noncompliance by our distributors, branded stores and other retail outlets could, among other things, negatively affect our brand reputation, demands for our products and our relationships with other distributors, branded stores and other retail outlets. In the event that our

22

Table of Contents

distributors, branded stores and other retail outlets are subject to administrative proceedings, penalties and fines for their operations due to reasons not attributable to us, it may cause disruption to the supply and sales of our products. Our agreements with our distributors and RELX Branded Partner Stores generally require them to make a deposit in order to compensate us for any losses we may incur as a result of any breaches of these agreements by them. However, such limited amounts may not be sufficient to cover our losses arising from product liability issues. Furthermore, we may be required to make filings with relevant PRC authorities with respect to RELX Branded Partner Stores as these store operators may be deemed to be franchisees under PRC law. If we fail to complete such filings in due course, we may be subject to penalties or fines, or even be compelled to adjust our management over such stores. Any of these could have a material and adverse effect on our business, financial condition, results of operations and prospects.

        We request our distributors and retailers to provide various important information and data with respect to their sales performance, inventory levels, the number of retail outlets that have placed orders with them and other operating metrics to effectively manage our distribution and retail network and optimize supply chain and production planning. Although we have implemented various measures, policies and standards with respect to our distributors' and retailers' internal control and ethical practices, there is no assurance that such information and data from them will be truthful or accurate. If our distributors and retailers fail to provide us truthful information or accurate data on their operating metrics, our distribution and retail management and supply chain and production planning may become ineffective, and our business and results of operations may be materially and adversely affected.

        In addition, we have identified cases where our products are sold in regions, distribution channels or retail outlets outside of our distribution and retail network without our authorization. We may not be able to prevent, detect or take effective measures against such unauthorized sales in a timely, effective manner, or at all. Such unauthorized sales could disrupt our management of distribution and retail network, hinder our implementation of distribution strategy in particular areas, and adversely affect our business and results of operations.

We may fail to continue to develop, innovate and utilize our technologies, which are core to our success.

        We believe our technologies are core to our success and are critical to our business. Our products are empowered by our proprietary technological innovations, such as e-liquid formulation, the engineering of the cartridge structure and the Essential Elements Solutions, to optimize adult smokers' experience with our products. However, we cannot assure you that we can keep up with the fast pace of the technology industry, especially the technologies applicable and related to e-vapor products, and continue to develop, innovate and utilize our proprietary capabilities. In particular, e-vapor technologies are still at an early stage. New solutions and technologies developed and introduced by competitors could render our technologies obsolete. Developing and integrating new technologies into our existing products could be expensive and time-consuming. We may not succeed in developing and incorporating new technologies at all. If we fail to continue to develop, innovate and utilize technologies effectively and on a timely basis, our business, financial performance and prospects could be materially and adversely affected.

We may not be able to develop and introduce new products or upgrade existing products in a timely and cost-effective manner, which may adversely affect our business, results of operations and prospects.

        To optimize adult smokers' experience, we must introduce new products and upgrade our existing products to meet our users' evolving preferences. It is difficult to predict the preferences of our users or a specific segment of users. Changes and upgrades to our existing products may not be well received by our users, and newly introduced products may not achieve expected results. Going forward, we may introduce new products with different features. Such efforts may require substantial investments of

23

Table of Contents

additional human capital and financial resources. If we fail to improve our existing products or introduce new ones in a timely or cost-effective manner, our ability to attract and retain users may be impaired, and our results of operations and prospects may be adversely affected.

        Although we endeavor to understand user preferences through surveys, sampling and other forms of interactions from time to time, we cannot assure you that we can anticipate, identify, develop or market products that respond to changes in users' preferences and expectations. For example, our surveys may not yield accurate or useful insights on user behaviors, and feedbacks on our products may be different after such products are commercially available to a wider public. There can be no assurance that any of our new products will achieve market acceptance or generate sufficient revenues to offset the costs and expenses incurred in relation to our development and promotion efforts. There can be no assurance that each of our new products will achieve market acceptance and be successful.

Our business, financial condition and results of operations may be adversely impacted by product defects or other quality issues.

        Our products may contain defects that are not detected until after they are shipped or inspected by our users. Our failure to maintain the consistency and quality throughout our production process could result in substandard quality or performance of our products, and product defects could cause significant damage to our market reputation and reduce our sales and market share. For example, the products we distribute may contain lithium-ion or similar types of batteries. Defects in these products could result in personal injury, property damage, pollution, release of hazardous substances or damage to equipment and facilities. As we primarily rely on several suppliers and manufacturers to supply raw materials and produce our products, if there is any inherent defects in the raw materials or our manufacturers do not produce products that meet the industrial and our standards, we may fail to maintain our quality control over our products. Actual or alleged defects in the products we distribute may give rise to claims against us for losses and expose us to claims for damages. If we deliver any defective products, or if there is a perception that our products are of substandard quality, we may incur substantial costs associated with mass product recall, product returns and replacements and significant warranty claims, our credibility and market reputation could be harmed and our results of operations and market share may be adversely affected.

        Further, defective products may result in compliance issues that could subject us to administrative proceedings and unfavorable results such as product recall and other actions. Such proceedings and unfavorable results could have a material adverse effect on our brand, reputation and results of operations.

We are subject to supply shortages and interruptions, long lead times, and price fluctuations for key raw materials and components, any of which could disrupt our supply chain and have a material adverse impact on our results of operations.

        Mass production of our products requires timely and adequate supply of various raw materials and components. We rely on third-party suppliers and manufacturers to source components and raw materials for production of our products, and some of these key components and raw materials are sourced from a limited number of suppliers. Therefore, we are subject to risks of shortages or discontinuation in supply, long lead times, cost increases and quality control issues with our suppliers. In addition, some of our suppliers may have more established relationships with our competitors and may choose to limit or terminate their relationships with us or prioritize our competitors' orders in the case of supply shortages.

        In the event of a component or raw material shortage or supply interruption from suppliers, we will need to identify alternative sources of supply, which can be time-consuming, difficult to locate, and costly. We may not be able to source these components or raw materials on terms that are acceptable

24

Table of Contents

to us, or at all, which may undermine our ability to meet our production requirements or to fill distributor orders in a timely manner. This could cause delays in shipment of our products, harm our relationships with distributors, retailers and other business partners, and adversely affect our results of operations. In addition, there are laws and regulations that pose restrictions and requirements on certain raw materials and components of our products. Changes in the regulatory landscape of such raw materials and components may pose additional restrictions or requirements on such raw materials and components, which may further adversely affect the supply of such regulated raw material and components. If we fail to address such risk, our business, results of operations and financial condition may be materially and adversely affected.

        Moreover, market prices for certain raw materials have been volatile. For example, we have experienced fluctuations in the market prices for certain important raw materials used in production in the past, and may continue to experience such fluctuations in the future. We may not be able to recover these costs through selling price increases, which would have a negative effect on our results of operations.

        Human capital and equipment are also key elements in the overall manufacturing process. As the production process requires significant manpower and equipment, failure to effectively manage and address the risks relating to manpower shortage or equipment insufficiency could cause significant interruptions and delays to our production, which may in turn have a material and adverse impact on our results of operations.

If our retailers or customer representatives fail to provide satisfactory services to users or comply with applicable laws, regulations and policies, our brand, business, results of operations and prospects may be materially and adversely affected.

        Our products are primarily sold in our offline retail outlets through our distributors, retailers and customer representatives. We rely on these offline retail outlets to showcase our products to potential users. Even though we provide rigorous and regular trainings to help them understand our products and improve the quality of their services, there can be no assurance that they will provide satisfactory services to our existing and prospective users that will lead to purchases. Their failure to provide superior in-store experience may impair the willingness of our existing and prospective users to use and purchase our products, which in turn may materially and adversely affect our results of operations and prospects. In addition, we also rely on our distributors, retailers and customer representatives to avoid in-store underage purchases. Even though we continually stress our principles and require our distributors, retailers and customer representatives to adhere to our recommended measures to prevent underage purchases of our products, there is no guarantee that our distributors, retailers and customer representatives will strictly comply with such requirements. We also expect our distributors, retailers and customer representatives to provide other comprehensive services to our users, including collecting feedbacks from users. If they fail to provide satisfactory services to users, our brand image could be negatively affected, which could have a material and adverse effect on our business, results of operations and financial condition.

Outbreaks of communicable diseases, natural disasters or other events may materially and adversely affect our business, results of operations and financial condition.

        Our business could be adversely affected by the effects of communicable diseases and epidemics. In recent years, there have been breakouts of epidemics in China and globally. In early 2020, there was an outbreak of a novel strain of coronavirus, later named COVID-19, in China and many parts of the world. The outbreak of COVID-19 has severely impacted China and the rest of the world. In response to intensifying efforts to contain the spread of the coronavirus, the Chinese government took a number of actions, which included extending the Chinese New Year holiday, temporary closure of corporate offices, retail outlets and manufacturing facilities, quarantining individuals in China who had

25

Table of Contents

COVID-19, asking citizens to remain at home and to avoid gathering in public, and other actions. In light of such circumstances, our corporate office was closed for a certain period of time. Our production was adversely affected and some of our retail outlets were also closed for a certain period of time. These measures adversely impacted our production, sales and general operation for the first quarter of 2020. The COVID-19 global pandemic has resulted in, and may intensify, global economic distress, and the duration and extent of the impact of COVID-19 outbreak is highly uncertain at this time. The extent to which it may affect our results of operations, financial condition and cash flows will depend on the future development of the outbreak, which is also highly uncertain. Such uncertainty poses operational challenges to our production and inventory management. Our business and operations could be disrupted if any of our employees, distributors, retailers or manufacturers is suspected of having COVID-19, H1N1 flu, avian flu or another epidemic in our offices, within our distribution and retail channels or at the manufacturing facilities of the manufacturers, since it could require all of the possible contact persons to be quarantined and/or their offices to be disinfected. In addition, our results of operations could be adversely affected to the extent that the outbreak harms the PRC economy in general.

        We are also vulnerable to natural disasters and other calamities. Our production and storage facilities and research laboratories as well as our retail outlets are located at several leased properties. We cannot assure you that such properties will have adequate measures to protect itself from the effects of fire, floods, typhoons, earthquakes, power loss, telecommunications failures, break-ins, war, riots, terrorist attacks or similar events. Any of the foregoing events may give rise to cease of operations, which could cause the loss or corruption of products as well as adversely affect our ability to produce and distribute our products.

Misuse or abuse of our products may lead to potential adverse health effects, subjecting us to complaints, product liability claims and negative publicity.

        We are unable to control how our users choose to use our products. For example, we cannot prevent the users from misusing or abusing our products or the underage from doing so if they somehow get access to our products. Our users may also use our products to inhale chemicals obtained from informal sources and in other potentially hazardous applications that can result in personal injury, product liability and environmental claims.

        Misuse or abuse of our products, including use of our products in combination with other products and components from third parties, may significantly and adversely affect the health of our users, subjecting us to user complaints and product liability litigations, even though such products were not used in the manner recommended by us. Applicable law may render us liable for damages without regard to negligence or fault. Regardless of whether these complaints or product liability litigations hold merit, they may be costly and time-consuming to resolve, bring negative publicity that could damage our reputation and result in higher scrutiny by the government or stricter regulations, all of which could materially and adversely affect our business, financial condition and results of operations.

We rely on a limited number of suppliers and manufacturers to supply and produce our products. Loss of any of those business partners would materially and adversely affect our business.

        We rely on a limited number of suppliers and manufacturers to supply and produce our products. In particular, a majority of our products are currently produced at an exclusive production plant that we manage in cooperation with a third-party operational partner. Any interruption of the operations of our suppliers and manufacturers, any failure of suppliers and manufacturers to accommodate our fast growing business scale, any termination or suspension of our agreements with those parties, any change of terms in our agreements, or the deterioration of relationship with these suppliers and manufacturers may materially and adversely affect our results of operations. For example, those suppliers and manufacturers were all closed or ceased their operations for part of the first quarter of 2020 due to the

26

COVID-19 outbreak. Therefore, our business operation was adversely affected. In the event that our key business partners experience any operational difficulties including equipment breakdowns, labor strikes or shortages, natural disasters, component or material shortages, cost increases, violation of environmental, health or safety laws and regulations, health epidemics, or other problems, such difficulties will cause significant interruption to our business operations, as we may not be able to address such difficulties in a timely or cost-effective manner. We may be unable to pass potential cost increases to our users. We may have disputes with these business partners, which may result in litigation expenses, divert our management's attention and cause supply shortages to us. In addition, we may not be able to renew contracts with these suppliers and manufacturers or identify or enter into new agreements with them for additional services or for more favorable terms.

        Any failure of such suppliers, manufacturers and third-party service providers to perform with regards to quantity, quality or timely supply of products may have a material negative impact on our business and results of operations. Furthermore, although our agreements with our manufacturers contain provisions imposing confidentiality obligations on them, and we have adopted security protocols to ensure knowhow and technologies for manufacturing our products could not be easily leaked or plagiarized, we cannot guarantee the effectiveness of these efforts and, any leakage or plagiary of our knowhow and technologies could be detrimental to our business prospects and results of operations.

        In addition, any lack of requisite approvals, licenses or permits applicable to our suppliers or manufacturers may have a material and adverse impact on our business. In accordance with the relevant laws and regulations, our suppliers and manufacturers may be required to maintain various approvals, licenses and permits to operate their business, including but not limited to those relating to the supply and production of our products. There can be no assurance that our suppliers and manufacturers can maintain their requisite approvals, licenses or permits applicable to their business at all times or obtain such approvals, licenses or permits at all. In the event that they are not in compliance with such approvals, licenses or permits requirements, there can be no guarantee that they will rectify such incompliance in a timely manner or at all, which may adversely affect the supply and production of our products. As a result, our business, results of operations and financial condition may be materially and adversely affected.

Any disruption of the exclusive production plant or our third-party manufacturers' and suppliers' production plants could materially and adversely affect our business and results of operations.

        Currently, our products are primarily produced at the exclusive production plant and, to a lesser extent, at third-party manufacturers' production plants. We also rely on our suppliers to produce raw materials and components of our products. Nevertheless, natural disasters or other unanticipated catastrophic events, including storms, fires, explosions, earthquakes, terrorist attacks and wars, as well as changes in governmental planning for the land where the exclusive production plant or those third-party manufacturers' and suppliers' production plants are located could significantly impair our ability to manufacture our products and operate our business. Catastrophic events could also destroy the inventories stored in the exclusive production plant and those third-party manufacturers' and suppliers' production plants. The occurrence of any catastrophic event could result in the temporary or long-term closure of manufacturing facilities, and severely disrupt our business operations.

        In addition, the production plants are subject to environmental inspections and regulations. As of the date of this prospectus, the exclusive production plant operated by the third-party operational partner was not in strict compliance with such environmental inspections and regulations based on our knowledge. If such facilities fail to rectify and pass the environmental inspections or comply with relevant environmental requirements relating to production activities in a timely manner, they may be subject to fines, cohesive rectification, suspension and closure, which may materially and adversely affect the production of the exclusive production plant and in turn may impact our business. In addition, the exclusive production plant and the third-party manufacturers' and suppliers' production

27

Table of Contents

plants are also subject to health and safety laws and regulations imposed by the PRC governmental authorities to ensure a healthy and safe production environment. Failure to comply with the existing and future health and safety laws and regulations could subject the production plants to monetary damages and fines, disruption to production plans, suspension of their operations, which may in turn materially and adversely affect our business operations. Furthermore, if any on-site personnel at the exclusive production plant or any third-party manufacturers' and suppliers' production plants is suspected of having any communicable diseases, such as COVID-19, such production plants may be subject to temporary closure and quarantine requirements, which may in turn materially and adversely affect our business operations. For example, the exclusive production plant was closed for part of the first quarter of 2020 in accordance with the local temporary closure requirement attributable to COVID-19, which adversely affected our business operation.

        Furthermore, the exclusive production plant is located on leased properties comprising of over 20,000 square meters. Though such leases are renewable upon expiration, our ability to renew existing leases upon their expiration is crucial to our production activities, operations and profitability. If we are unable to negotiate for a renewal of the relevant leases, we may be forced to relocate our production bases and it may be difficult and costly to replace or relocate the exclusive production plant and equipment on a timely basis. We have not registered the lease agreement relating to the exclusive production plant with the PRC governmental authorities as required by PRC law. As a result, we may be ordered by the PRC government authorities to rectify such noncompliance and, if such noncompliance is not rectified within a given period of time, we may be subject to fines imposed by PRC government authorities ranging from RMB1,000 and RMB10,000 for the lease agreement that has not been registered with the relevant PRC governmental authorities. If we fail to address the risks mentioned above, our production will be materially and adversely affected. See also "—We are subject to risks relating to our leased properties."

        If we experience any unanticipated disruptions to us or our third-party manufacturers or if we are unable to renew our current leases, our production will be severely disrupted, which may in turn materially and adversely affect our business, financial condition and results of operations. Even though the third-party operational partner is contractually obligated to adjust and switch the production to other resources for us in the event that the production at the exclusive production plant is disrupted, there can be no assurance that the third-party operational partner will fulfill such contractual obligation or will be able to provide us with sufficient and satisfactory production lines to ensure the quality and quantity of our products manufactured.

We are subject to risks relating to the warehousing and logistics of our products. If any of these risks materializes, our business, financial condition and results of operations could be materially and adversely affected.

        We operate our warehouse facility on leased premises. Natural disasters or other unanticipated catastrophic events, including power interruptions, water shortage, storms, fires, earthquakes, cybersecurity attacks, terrorist attacks and wars, as well as changes in governmental planning for the land underlying the warehousing facility, could destroy any inventory located in these facilities and significantly impair our business operations. Furthermore, the lease for the warehousing facility that we use could be challenged by third parties or government authorities, which may cause interruptions to our business operations. We cannot assure you that our use of such leased properties will not be challenged. In the event that our use of leased properties is successfully challenged, we may be subject to fines and forced to relocate the affected operations. We can provide no assurance that we will be able to find suitable replacement sites on terms acceptable to us on a timely basis, or at all, or that we will not be subject to material liability resulting from third parties' challenges on our use of such properties.

28

        We also rely on third-party logistics service providers to deliver products to our distributors. Logistics and transit to final destination may be disrupted for a number of reasons that may be beyond our control or the control of our logistics service providers, including, without limitation, epidemics, inclement weather, natural disasters, transportation interruptions or labor unrest or shortage. Such interruptions to or failures in such third-party logistics service providers' operations may obstruct the timely or successful delivery of our products. If products are not delivered on time or are delivered in a damaged state, our distributors and retailers may return the products and may claim refund from us and distributors' and retailers' confidence in us may be impaired. If any of our logistics service providers' operations or services are disrupted or terminated, we may not be able to find alternative service providers with quality and on commercial terms to our satisfaction in a timely and reliable manner, or at all. As a result, our business, financial condition and results of operations may be materially and adversely affected.

Failure to manage inventory at optimal levels could adversely affect our business, financial condition and results of operations.

        We are required to manage a large volume of inventory effectively for our business. We depend on our demand forecasts for our products to make procurement plans, manufacturing decisions and manage our inventory. Our forecast for demands, however, may not accurately reflect the actual market demands, which depends on a number of factors including, without limitation, launches of new products, changes in product life cycles and pricing, product defects, changes in user spending patterns, manufacturer back orders and other suppliers/manufacturers-related issues, distributors' and retailers' procurement plans, as well as the volatile economic environment in China. We do not have long-term contracts with some of our distributors, which makes the demands for our products from distributors unstable and unpredictable. In addition, when we launch a new product with new components or raw material, it may be difficult to establish supplier relationships, determine appropriate raw material and product selection, and accurately forecast market demand for such product. We cannot assure you that we will be able to maintain proper inventory levels for our business at all times, and any such failure may have a material and adverse effect on our business, financial condition and results of operations.

        Inventory levels in excess of distributor demand may result in inventory write-downs, expiration of products or an increase in inventory holding costs and a potential negative effect on our liquidity. As we plan to continue expanding our product offerings, we expect to include more products in our inventory, which will make it more challenging for us to manage our inventory effectively and will put more pressure on our warehousing system. If we fail to manage our inventory effectively, we may be subject to a heightened risk of inventory obsolescence, a decline in inventory values, and significant inventory write-downs or write-offs. In addition, we may be required to lower sale prices in order to reduce inventory level, which may lead to lower gross margins. High inventory levels may also require us to commit substantial capital resources, preventing us from using that capital for other important purposes. Any of the above may materially and adversely affect our results of operations and financial condition.

        Conversely, if we underestimate distributor demand, or if our suppliers or contract manufacturers fail to provide products to us in a timely manner, we may experience inventory shortages, which may, in turn, require us to manufacture our products at higher costs, result in unfulfilled user orders, leading to a negative impact on our financial condition and our relationships with distributors.

        Additionally, the distributors largely determine the inventory levels of the retail outlets they operate based on their estimation, and such inventory levels might not correspond to actual market demands and could lead to under-stocking or over-stocking in the retail outlets they operate. Therefore, although we try to monitor inventory levels in these retail outlets to the extent we can, we cannot assure you that there will not be under-stocking or over-stocking in these stores. Under-stocking can lead to missed sales opportunities, while over-stocking could result in inventory depreciation and

29

decreased shelf space for stocks that are in higher demands. These results could adversely affect our business, financial condition and results of operations.

Our investments in scientific research may not generate results as anticipated.

        To better serve adult smokers, we are dedicated to the scientific research of e-vapor products and endeavor to achieve advances in scientific research in harm reduction principles and methods. We operate two laboratories located in Shenzhen, China to conduct our scientific research, focusing on the assessment and research of e-liquid and health risks associated with vaping. However, as scientific research is subject to significant uncertainties, there can be no assurance that our investments in such efforts will make material progress or improve our profitability in a timely and cost-effective manner, or at all. We may not be able to generate sufficient revenue from our scientific research efforts to offset the costs and expenses incurred, which may cause adverse effect to our financial condition and results of operations.

We face competition from players in e-vapor industry and may fail to compete effectively.

        The e-vapor industry in China is intensely competitive. We face a variety of competitive challenges with respect to sourcing raw materials and products efficiently, pricing our products competitively, anticipating and quickly responding to changes in user preference, maintaining favorable brand recognition and providing quality services, finding manufacturing, warehousing and logistics solutions of good quality, and other potential challenges. In addition, our suppliers, distributors and retailers may cease their cooperation with us, build up their own e-vapor brand and compete with us. We may also be subject to competition from established overseas e-vapor product brands. If we cannot properly address these competitive challenges, our business and prospects would be materially and adversely affected.

        Some of our current and potential competitors may have greater financial, marketing, ordering quantities, portfolios of products and intellectual properties and other resources. Certain competitors may be able to secure raw materials and products from suppliers and manufacturers on more favorable terms, devote greater resources to marketing and promotional campaigns, adopt more aggressive pricing or inventory policies, and devote substantially more resources to product development and technology. Increased competition may adversely affect our results of operations, market share and brand recognition, or force us to incur losses. There can be no assurance that we will be able to successfully compete against current and future competitors, and competitive pressures may have a material adverse effect on our business, prospects, financial condition and results of operations.

Our parent company Relx Inc. uses our brand and licenses our trademarks and certain other proprietary rights for overseas markets and may fail to maintain our brand image as our licensee.

        We have entered into an intellectual property license agreement with Relx Inc., effective upon the completion of this offering, to license certain of our proprietary rights, such as trademarks, patents or copyrighted materials, to our parent company Relx Inc. for the production and sale of e-vapor products in markets outside of China in accordance with the non-competition agreement we have entered into with Relx Inc. We expect Relx Inc. to maintain the value of our RELX brand in overseas markets. Although we strive to protect our brand through various contractual arrangements under the intellectual property license agreement, we cannot completely control the use of our brand, trademarks or other proprietary rights by Relx Inc., and there is no guarantee it will fully comply with our intellectual property license agreement at all time. Any misuse of our brand, trademarks or other proprietary rights by Relx Inc., its distributors or other business partners, any negative publicity associated with Relx Inc., its distributors or other business partners, or products under the "RELX" brand, or any negative development in respect of Relx Inc.'s business, financial condition, or in terms of compliance with legal or regulatory requirements in any market, may have an adverse impact on our brand, reputation and business.

Table of Contents

        There have been cases of unauthorized distribution of our products in the markets outside of China and such those unauthorized distributors may continue to distribute our products without our or Relx Inc.'s authorization and bypassing distribution and retail network screening procedures of ours and Relx Inc.'s. Our brand image may be materially and adversely affected if such unauthorized distribution leads to quality issue, product defects or any other more serious concerns towards our products and public perception. As unauthorized distribution may be beyond our control, there can be no assurance that we can detect such unauthorized distribution in a timely manner or at all, or we are able to prohibit or prevent such unauthorized distribution.

We may not be successful in implementing our future business plans and strategies, and if we are unable to execute them effectively and efficiently, our business, financial condition, results of operations and growth prospects may be materially and adversely affected.

        Our business has become increasingly complex in terms of both product portfolio and scale. Any future expansion may increase the complexity of our operations and place a significant strain on our managerial, operational, financial and human resources. Our current and planned personnel, systems, procedures and control measures may not be adequate to support our future operations. We cannot assure you that we will be able to effectively manage our growth or to implement all these systems, procedures and control measures successfully. If we are unable to manage our growth effectively, our business and prospects may be materially and adversely affected.

        We may develop a number of new initiatives, strategies and operating plans designed to enhance our business. These initiatives may prove unsuccessful. Implementing these initiatives will require investments which may result in costs without generating any revenues and may therefore negatively affect our profitability. We may not be able to successfully complete these growth initiatives, strategies and operating plans and realize all of the benefits that we expect to achieve. If, for any reason, the benefits we realize are less than our estimates, or the implementation of these growth initiatives, strategies and operating plans adversely affects our operations, or it costs more or takes longer to effectuate than we expect, or if our assumptions prove inaccurate, our business, financial condition and results of operations may be materially and adversely affected.

Misconducts, including illegal, fraudulent or collusive activities, by our employees, distributors, retailers, suppliers and manufacturers, may harm our brand and reputation and adversely affect our business and results of operations.

        Misconduct, including illegal, fraudulent or collusive activities, unauthorized business conducts and behaviors, or misuse of corporate authorization by our employees, contractors, distributors, retailers, suppliers and manufacturers and other business partners could subject us to liability and negative publicity. Our employees, distributors, retailers, suppliers and manufacturers may conduct fraudulent activities, such as accepting payments from or making payments to other distribution channel participants or other third parties in order to bypass our internal system and to complete shadow transactions and/or transactions outside our official or authorized distribution channels, disclosing users' information to competitors or other third parties for personal gains, or applying for fake reimbursement. They may conduct activities in violation of unfair competition law, which may expose us to unfair competition allegations and risks. We cannot assure you that such incidents will not occur in the future. It is not always possible to identify and deter such misconduct, and the precautions we take to detect and prevent these activities may not be effective. Such misconduct could damage our brand and reputation, which could adversely affect our business and results of operations.

If we fail to fully comply with PRC Advertising Law and related regulations, rules and measures applicable to advertising, our business and results of operations may be adversely affected.

        PRC advertising laws, rules and regulations require advertisers, advertising operators and advertising distributors to ensure that the content of the advertisements they prepare or distribute is fair and accurate and is in full compliance with applicable laws. Further, certain provinces and cities in the PRC prohibit the advertisement of combustible tobacco products and e-vapor products. Violation of these laws, rules or regulations may result in penalties, including fines, confiscation of advertising fees and orders to cease dissemination of the advertisements, and potentially unfair competition liability. In circumstances involving serious violations, the PRC government may suspend or revoke a violator's business license. Even though we are not permitted to conduct comprehensive marketing activities, especially not online marketing in accordance with the October 2019 Announcement, we may still conduct selling activities to the extent permitted. Failure to comply with these requirements may lead to penalties and fines for any incompliance, which may render our efforts and costs incurred futile. As a result, our business and results of operations may be adversely affected.

We are subject to governmental regulations and other legal obligations related to privacy, information security, and data protection, and any security breaches, and our actual or perceived failure to comply with our legal obligations could harm our brand and business.

        We generate, collect, store and process a large amount of personal, transactional, statistical and behavioral data, including certain personal and other sensitive data from our users. We face risks inherent in handling large volumes of data and in securing and protecting such data. In particular, we face a number of data-related challenges related to our business operations, including:

•

protecting the data in and hosted on our system and cloud servers, including against attacks on our system and cloud servers by external 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.

        Although we have taken steps to protect such data, our security measures could be breached. As of the date of this prospectus, we have not experienced any material breach of our cybersecurity system or measures. As techniques used to sabotage or obtain unauthorized access to systems change frequently and generally are not recognized until they are launched against a target, we may be unable to anticipate these techniques or to implement adequate preventative measures. Any accidental or willful security breaches or other unauthorized access to our system and cloud servers could cause confidential information to be accessed, stolen and used for illegal or unauthorized purposes. Security breaches or unauthorized access to confidential information could also expose us to liability related to the loss of the information, time-consuming and expensive litigation and negative publicity. If security measures are breached because of third-party action, employee error, malfeasance or otherwise, or if design flaws in our technology infrastructure are exposed and exploited, our relationships with users, distributors, retailers, manufacturers or suppliers could be severely damaged, we could incur significant liability, and our business and operations could be adversely affected.

        In addition, PRC government authorities have enacted a series of laws and regulations in regard of the protection of personal information, under which telecommunication business operators, internet service providers and other value chain operators are required to comply with the principles of legality, justification and necessity, to clearly indicate the purposes, methods and scope of any information collection and usage, to obtain the consent of users, and to keep collected personal information confidential, as well as to establish user information protection system with appropriate remedial

32

Table of Contents

measures. However, there is uncertainty as to the interpretation and application of such laws which may be interpreted and applied in a manner inconsistent with our current policies and practices or require changes to the features of our system. We cannot assure you that our existing information protection system and technical measures will be considered sufficient under applicable laws and regulations. If we are unable to address any information protection concerns, or to comply with the then applicable laws and regulations, we may incur additional costs and liability and our reputation, business and operations might be adversely affected.

        We have obtained consent from our users to use their information within the scope of authorization, and we have taken technical measures to ensure the security of such information and prevent the information from being divulged, damaged or lost. However, since the Cyber Security Law and relevant regulations, rules and measures are relatively new, there are uncertainties as to the interpretation and application of these laws and regulations, and it is possible that our data protection practices are or will be inconsistent with regulatory requirements. Any violation of the provisions and requirements under the Cyber Security Law and other relevant regulations, rules and measures may subject us to warnings, fines, confiscation of illegal gains, revocation of licenses, suspension of business, shutting down of websites or even criminal liabilities. Complying with such requirements could cause us to incur substantial expenses or to alter or change our practice in a manner that could harm our business. Any systems failure or security breach or lapse that results in the unauthorized release of our user data could harm our reputation and brand and, consequently, our business, in addition to exposing us to potential legal liability.

Our intellectual property rights are critical to our success. Infringement of our intellectual property right by any third party or loss of our intellectual property rights may materially and adversely affect our business, financial condition and results of operations.

        We rely on a combination of trademark, patent, copyright and trade secret protection laws in China and other jurisdictions, as well as confidentiality procedures and contractual provisions, to protect our intellectual property rights. We also enter into confidentiality agreements with our employees and any third parties who may access our proprietary information, and we rigorously control access to our proprietary technology and information.

        Intellectual property protection may not be sufficient in China or other countries. Confidentiality agreements may be breached by counterparties, and there may not be adequate remedies available to us for any such breach. Accordingly, we may not be able to effectively protect our intellectual property rights or to enforce our contractual rights in China or elsewhere. For example, we have identified cases where counterfeit products associated with our brand infringed our intellectual property rights. However, policing any unauthorized use of our intellectual property is difficult, time-consuming, and costly, and the steps we have taken may be inadequate to prevent the misappropriation of our intellectual property. In the event that we resort to litigation to enforce our intellectual property rights, such litigation could result in substantial costs and a diversion of our managerial and financial resources. We can provide no assurance that we will prevail in such litigation. Furthermore, we may be subject to the risks of losing our intellectual property rights or the intellectual property rights licensed from other third-parties due to several reasons. Certain intellectual property rights, such as patents, are subject to a limited period of time. Upon the expiry of such period of time, others may freely use such intellectual properties without any license or charges, which may impose competitive harm to us and in turn adversely affect our business and prospects. The intellectual property rights that we currently have may also be revoked, invalidated or deprived by regulatory authorities as a result of intellectual property claims or challenges successfully raised by third parties. We may also rely on certain intellectual property rights licensed from other third parties. There can be no guarantee that we will be able to maintain such licenses at all times or renew such licenses upon expiry. Moreover, our trade secrets may be leaked or otherwise become available to, or be independently discovered by, our

33

Table of Contents

competitors. Any failure in maintaining, protecting or enforcing our intellectual property rights could have a material adverse effect on our business, financial condition and results of operations.

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

        We cannot be certain that our operations or any aspects of our business do not or will not infringe upon or otherwise violate patents, copyrights or other intellectual property rights held by third parties. We may, and from time to time in the future be, subject to legal proceedings and claims relating to the intellectual property rights of others. In addition, there may be other third-party intellectual property that is infringed by our products and services or other aspects of our business. There could also be existing patents of which we are not aware that we may inadvertently infringe. Our existing intellectual property rights may also infringe intellectual property rights of other third parties and our existing intellectual property rights may be revoked, invalidated or deprived if other third parties successfully raise challenges or claims against us. We cannot assure you that holders of patents purportedly relating to some aspect of our technology or business, if any such holders exist, would not seek to enforce such patents against us in China or any other jurisdictions. For example, we currently use certain design patents, which constitute immaterial components of our products, from third parties. If we fail to maintain the license of such design patents for our usage or identify alternative patents in a timely manner, we may be subject to intellectual property infringement claims from such third parties. Further, the application and interpretation of China's patent laws and the procedures and standards for granting patents in China are still evolving and are uncertain, and we cannot assure you that PRC courts or regulatory authorities would agree with our analysis. If we are found to have violated the intellectual property rights of others, we may be subject to liability for our infringement activities or may be prohibited from using such intellectual property, and we may incur licensing fees or be forced to develop alternatives of our own. In addition, we may incur significant expenses, and may be forced to divert management's time and other resources from our business and operations to defend against these third-party infringement claims, regardless of their merits.

Accidents, injuries or other harm suffered by visitors to the branded stores operated by ourselves may adversely affect our reputation, subject us to liability and cause us to incur substantial expenses.

        We could be held liable for accidents that occur at the branded stores operated by ourselves. In the event of personal injuries, fires or other accidents suffered by visitors or others working at or visiting the branded stores operated by ourselves, our stores may be perceived to be unsafe, which may discourage potential visitors from going to the branded stores operated by ourselves. Although we have not encountered any instances of serious injuries to the visitors to the branded stores operated by ourselves, we cannot assure you that there will not be any in the future.

        We could also face claims alleging that we should be liable for accidents or injuries caused by our employees or contractors due to negligence in supervision. Any material liability claim against us or any of our employees or contractors could adversely affect our reputation, create unfavorable publicity, cause us to incur substantial expenses and divert the time and attention of our management.

Our success and ability to operate efficiently are dependent on our key management personnel, and loss of service of our key management personnel or any failure to attract and retain necessary talents may materially and adversely affect our business, financial condition and results of operations.

        Our future success is significantly dependent upon the continued service of our key management personnel and other key employees, who have contributed significantly to our current achievements. There can be no assurance that we are able to retain all of our current key management personnel. Disputes may arise among our key management personnel and such disputes may result in departure of such personnel. If we lose the services of any member of management or other key personnel due to

34

Table of Contents

any reason, our business and growth prospects may be severely disrupted and we may not be able to locate suitable or qualified replacements and may incur additional expenses to recruit and train new staff. Competition for talents in China is intense, and the availability of suitable and qualified candidates in China is limited. Competition for these individuals could cause us to offer higher compensation and other benefits to attract and retain them. In addition, we may be subject to negative publicity or gossip surrounding the stability and changes in key management composition.

        Even if we were to offer higher compensation and other benefits such as share-based incentives, there is no assurance that these individuals will choose to join or continue to work for us. Any failure to attract or retain key management personnel could severely disrupt our business, growth, and our corporate culture. In addition, if any dispute arises regarding the agreements between our current or former key employees and us, we may have to incur substantial costs and expenses in order to enforce the agreements in China or we may be unable to enforce them at all. We also commit significant time and other resources to training our employees, which increases their value to competitors if they subsequently leave us for our competitors.

We have identified a material weakness in our internal control over financial reporting. If we do not adequately remediate this material weakness, or if we experience additional material weaknesses in the future or otherwise fail to maintain effective internal controls, we may not be able to accurately or timely report our financial condition or results of operations, or comply with the accounting and reporting requirements applicable to public companies, which may adversely affect investor confidence in us and the market price of our ADSs.

        Prior to this offering, we have been a private company and were never required to evaluate our internal control within a specified period, and, as a result, we may experience difficulty in meeting these reporting requirements in a timely manner. Our management has not completed assessment of the effectiveness of our internal control over U.S. GAAP financial reporting, and our independent registered public accounting firm has not conducted an audit of the effectiveness of our internal control over financial reporting. However, in the course of preparing and auditing our consolidated financial statements included in this prospectus, we and our independent registered public accounting firm respectively identified one material weakness in our internal control over financial reporting as of December 31, 2019. In accordance with reporting requirements set forth by the SEC, a "material weakness" is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our company's annual or interim consolidated financial statements will not be prevented or detected on a timely basis.

        The material weakness identified relates to lack of sufficient competent financial reporting and accounting personnel with appropriate understanding of U.S. GAAP to design and implement formal period-end financial reporting controls and procedures to address complex U.S. GAAP technical accounting issues, and to prepare and review the consolidated financial statements and related disclosures in accordance with U.S. GAAP and financial reporting requirements set forth by the Securities and Exchange Commission, or the SEC. Neither we nor our independent registered public accounting firm undertook a comprehensive assessment of our internal control under the Sarbanes-Oxley Act for purposes of identifying and reporting any material weakness in our internal control over financial reporting. We and they are required to do so only after we become a public company. Had we performed a formal assessment of our internal control over financial reporting or had our independent registered public accounting firm performed an audit of the effectiveness of our internal control over financial reporting, additional material weaknesses may have been identified.

        Upon the completion of this offering, we will become a public company in the United States subject to the Sarbanes-Oxley Act of 2002. Section 404 of the Sarbanes-Oxley Act of 2002 will require that we include a report of management on our internal control over financial reporting in our annual

report on Form 20-F beginning with our annual report for the fiscal year ending December 31, 2021. In addition, once we cease to be an "emerging growth company" as such term is defined in the JOBS Act, our independent registered public accounting firm must attest to and report on the effectiveness of our internal control over financial reporting. Our management may conclude that our internal control over financial reporting is not effective. Moreover, even if our management concludes that our internal control over financial reporting is effective, our independent registered public accounting firm, after conducting its own independent testing, may issue a report that is qualified if it is not satisfied with our internal controls or the level at which our controls are documented, designed, operated or reviewed, or if it interprets the relevant requirements differently from us. In addition, after we become a public company, our reporting obligations may place a significant strain on our management, operational and financial resources and systems for the foreseeable future. We may be unable to timely complete our evaluation testing and any required remediation.

        During the course of documenting and testing our internal control procedures, in order to satisfy the requirements of Section 404, we may identify other weaknesses and deficiencies in our internal control over financial reporting. In addition, if we fail to maintain the adequacy of our internal control over financial reporting, as these standards are modified, supplemented or amended from time to time, we may not be able to conclude on an ongoing basis that we have effective internal control over financial reporting in accordance with Section 404. If we fail to achieve and maintain an effective internal control environment, we could suffer material misstatements in our financial statements and fail to meet our reporting obligations, which would likely cause investors to lose confidence in our reported financial information. This could in turn limit our access to capital markets, harm our results of operations, and lead to a decline in the trading price of our ADSs.

        Additionally, ineffective internal control over financial reporting could expose us to increased risk of fraud or misuse of corporate assets and subject us to potential delisting from the stock exchange on which we list, regulatory investigations and civil or criminal sanctions. We may also be required to restate our financial statements from prior periods.

Future investments in and acquisitions of complementary assets, technologies and businesses may fail, and may result in equity and earnings dilution and significant diversion of management attention.

        We may invest in or acquire assets, technologies and businesses that are complementary to our existing business. This may include opportunities to strengthen our technology capabilities and product offerings. Our investments or acquisitions may not yield the results we expect. In addition, investments and acquisitions could result in the use of substantial amounts of cash, potentially dilutive issuances of equity securities, significant amortization expenses related to intangible assets, significant diversion of management attention and exposure to potential unknown liabilities of the acquired business. Moreover, the cost of identifying and consummating investments and acquisitions, and integrating the acquired businesses into ours, may be significant, and the integration of acquired businesses may be disruptive to our existing business operations. In the event that our investments and acquisitions are not successful, our results of operations and financial condition may be materially and adversely affected.

We may not be able to obtain additional capital when desired, on favorable terms or at all.

        We may make investments from time to time in technologies, facilities, equipment, hardware, software and other projects to remain competitive. Due to the unpredictable nature of the capital markets and our industry, there can be no assurance that we will be able to raise additional capital on terms favorable to us, or at all, if and when required, especially if we experience disappointing results of operations. If adequate capital is not available to us as required, our ability to fund our operations, take advantage of unanticipated opportunities, develop or enhance our infrastructure or respond to competitive pressures could be significantly limited. If we do raise additional funds through the
