116,500,000 American Depositary Shares

RLX Technology Inc.

Representing 116,500,000 Class A Ordinary Shares

         This is an initial public offering of American depositary shares, or ADSs, of RLX Technology Inc.

         We are offering 116,500,000 ADSs to be sold in the offering.

         Prior to this offering, there has been no public market for our ADSs or ordinary shares. Each ADS represents one Class A ordinary share, par value US$0.00001 per share. Our ADSs have been approved for listing on the New York Stock Exchange under the symbol "RLX."

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

         Immediately prior to the completion of this offering, our authorized share capital will consist of Class A ordinary shares and Class B ordinary shares. Relx Inc. will beneficially own all of our issued Class B ordinary shares. These Class B ordinary shares will constitute approximately 92.5% of our total issued and outstanding share capital immediately after the completion of this offering and 99.2% of the aggregate voting power of our total issued and outstanding share capital immediately after the completion of this offering, assuming the underwriters do not exercise their over-allotment option. Within six months following this offering, the existing shareholders of Relx Inc. would become our shareholders through a distribution of our shares in proportion to Relx Inc.'s shareholding structure at the time. Upon the completion of such share distribution, the existing shareholders of Relx Inc. will hold Class A ordinary shares of our company except for Relx Holdings Limited, which will beneficially own 618,171,790 Class B ordinary shares. The Class B ordinary shares then beneficially owned by Relx Holdings Limited will represent all of our issued and outstanding Class B ordinary shares upon the completion of the share distribution and will constitute approximately 39.8% beneficial ownership or 86.9% voting power of our total issued and outstanding share capital immediately after the completion of the share distribution, assuming the underwriters do not exercise their over-allotment option in this offering. 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 will be entitled to one vote, and each Class B ordinary share will be entitled to ten votes and will be 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.

         Following the completion of this offering and assuming that Relx Inc. remains our parent company, we will be a "controlled company" as defined under the NYSE Listed Company Manual because Relx Inc. will hold all of our then outstanding Class B ordinary shares, representing 99.2% of our total voting power, assuming that the underwriters do not exercise their over-allotment option, or 99.1% of our total voting power if the underwriters exercise their over-allotment option in full. We currently expect that we will continue to be a "controlled company" after the completion of the abovementioned shareholding change as Relx Holdings Limited, a British Virgin Islands company controlled by Ms. Ying (Kate) Wang, the chairperson of our board of directors and chief executive officer, will hold all of our then outstanding Class B ordinary shares, representing more than 50% of our total voting power.

         Investing in the ADSs involves risks. See "Risk Factors" beginning on page 20 for factors you should consider before buying the ADSs.

PRICE US$12.00 PER ADS

         Neither the 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.

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

20

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, Nanning and Chongqing, 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 PRC Civil Code 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

22

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

24

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

25

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

26

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

27

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

28

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

29

Table of Contents

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

30

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.

31

        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

32

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

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

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

37

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.

        We have 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 requires 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

38

Table of Contents

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, as we have 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

39

Table of Contents

issuance of equity or convertible debt securities, the ownership interests of our shareholders could be significantly diluted. These newly issued securities may have rights, preferences or privileges senior to those of existing shareholders.

We may be subject to legal or other proceedings in the ordinary course of our business. If the outcomes of these proceedings are adverse to us, they could have a material adverse effect on our business, financial condition and results of operations.

        During the ordinary course of our business operations, we may be involved in legal disputes or regulatory and other proceedings relating to, including but not limited to, contractual disputes, product liability claims and employees' claims. Especially, for contractual disputes, we cannot assure you that the venue and governing law agreed in relevant contracts are always favorable to us. Any such legal disputes or proceedings may subject us to substantial liabilities and may have a material and adverse effect on our reputation, business, financial condition and results of operations. Among those proceedings, some of them may be relating to our industry position in e-vapor market or by complaints from third parties. Especially, our industry position in e-vapor market may draw heightened scrutiny from the regulatory authorities or cause to be paid close attention to our business operation. In addition, if we were to be involved in anti-monopoly and competition laws and regulations related scrutiny or action, governmental agencies and regulators may take certain actions, which may subject us to significant fines or penalties and restrictions imposed on our options. Due to the uncertainty of legislation and local implementation of anti-monopoly and competition laws and regulations in the PRC, we cannot assure you that we will not be subject to any investigations, claims or complaints of alleged violations of these laws and regulations.

        If we become involved in material or protracted legal proceedings or other legal disputes in the future, we may incur substantial legal expenses and our management may need to devote significant time and attention to handle such proceedings and disputes, thereby diverting their attention from our business operations. In addition, the outcome of such proceedings or disputes may be uncertain and could result in settlement or outcomes which may adversely affect our business, financial condition and results of operations.

We have granted and may continue to grant share options and other share-based awards in the future, which may result in increased share-based compensation expenses.

        Our parent company Relx Inc. adopted equity incentive plans and we granted share-based compensation awards under such plans to our employees, directors and consultants to incentivize their performance and align their interests with ours. We have adopted a 2021 share incentive plan, or the 2021 Plan, effective upon the completion of this offering, and expect to assume all outstanding share incentive awards granted under the equity incentive plans of Relx Inc. For further detailed information, please refer to "Management—Share Incentive Plans." We recorded share-based compensation expenses of RMB6.8 million for the 2018 period, RMB52.7 million (US$7.8 million) for the year ended December 31, 2019 and RMB273.0 million (US$40.2 million) for the nine months ended September 30, 2020. We believe the granting of share-based compensation is of significant importance to our ability to attract and retain key personnel and employees, and we will continue to grant share-based compensation to employees in the future. As a result, our expenses associated with share-based compensation may increase upon the completion of this offering and afterwards, which may have an adverse effect on our results of operations.

Failure to comply with PRC labor laws and make adequate contributions to various employee benefits plans as required by PRC regulations may subject us to penalties.

        Companies operating in China are required to participate in various government-sponsored employee benefit plans, including certain social insurance, housing funds and other welfare-oriented

40

Table of Contents

payment obligations, and contribute to the plans in amounts equal to certain percentages of salaries, including bonuses and allowances, of employees up to a maximum amount specified by the local government from time to time at locations where our employees are based. The requirements of employee benefit plans have not been implemented consistently by the local governments in China given the different levels of economic development in different locations. If we are determined by local authorities to fail to make adequate contributions to any employee benefits as required by relevant PRC regulations, we may face late fees or fines in relation to the underpaid employee benefits. In addition, our provision for these liabilities may not be adequate, particularly in light of the recent tightening regulations. As a result, our financial condition and results of operations may be materially and adversely affected.

If we are not able to control our labor costs in an effective way, our business, results of operations and financial condition may be adversely affected.

        Our labor costs are primarily incurred in China. The economy of China has been experiencing significant growth, leading to inflation and increased labor costs, particularly in the large cities, such as Beijing. In addition, we are required by PRC laws and regulations to pay various statutory employee benefits, including pensions, housing fund, medical insurance, work-related injury insurance, unemployment insurance and maternity insurance to designated government agencies for the benefit of our employees. We expect that our labor costs in China, including wages and employee benefits, will continue to grow as our business grows in scale. Significant additional government-imposed increases in the cities of China where we have operations may affect our profitability and results of operations.

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

        COVID-19 had a severe and negative impact on the global and China's economy in the first quarter of 2020. Whether this will lead to a prolonged downturn in the economy is still unknown. Even before the outbreak of COVID-19, the global macroeconomic environment was facing challenges, including the end of quantitative easing by the U.S. Federal Reserve, the economic slowdown in the Eurozone since 2014, uncertainties over the impact of Brexit and the ongoing global trade disputes and tariffs. The growth of China's economy has slowed down since 2012 compared to the previous decade and the trend may continue. There is considerable uncertainty over the long-term effects of the monetary and fiscal policies adopted by the central banks and financial authorities of some of the world's leading economies, including the United States and China. In addition, there have also been concerns about the relationship between China and the United States, resulted from the current trade tension between the two countries. There have been further uncertainties related to the drastic drop in oil prices and the U.S. Federal Reserve's progressive policies to strengthen the market in early 2020. It is unclear whether these challenges and uncertainties will be contained or resolved and what effects they may have on the global political and economic conditions in the long term. Economic conditions in China are sensitive to global economic conditions, as well as changes in domestic economic and political policies and the expected or perceived overall economic growth rate in China. Any prolonged slowdown in the global or Chinese economy may have a negative impact on our business, results of operations and financial condition, and continued turbulence in the international markets may adversely affect our ability to access the capital markets to meet liquidity needs. Our users and business partners may reduce or delay spending with us, while we may have difficulty expanding our user base and cooperative network fast enough, or at all, or to offset the impact of decreased spending by our existing users and business partners.

We have limited insurance coverage of our operations, which may expose us to significant costs and business disruption.

        The insurance industry in China is still in an early stage of development, and insurance companies in China currently offer limited business-related insurance products. We do not maintain business interruption insurance or general third-party liability insurance. We consider this practice to be reasonable in light of the nature of our business and the insurance products that are available in China and in line with the practices of other companies in the same industry of similar size in China. Any uninsured risks may result in substantial costs and the diversion of resources, which could adversely affect our results of operations and financial condition.

We are subject to risks relating to our leased properties

        We lease real properties from third parties primarily for our office, the branded stores operated by ourselves and production facilities in China, and most of these lease agreements for these properties have not been registered with the PRC governmental authorities as required by PRC law. Although the failure to do so does not in itself invalidate the leases, 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 each lease agreement that has not been registered with the relevant PRC governmental authorities.

        The ownership certificates or other similar proof of most of our leased properties have not been provided to us by the relevant lessors. Therefore, we cannot assure you that such lessors are entitled to lease the relevant real properties to us. If the lessors are not entitled to lease the real properties to us and the owners of such real properties decline to ratify the lease agreements between us and the respective lessors, we may not be able to enforce our rights to lease such properties under the respective lease agreements against the owners. As of the date of this prospectus, we are not aware of any claim or challenge brought by any third parties concerning the use of our leased properties without obtaining proper ownership proof. If our lease agreements are claimed as null and void by third parties who are the real owners of such leased real properties, we could be required to vacate the properties, in the event of which we could only initiate the claim against the lessors under relevant lease agreements for indemnities for their breach of the relevant leasing agreements. We cannot assure you that suitable alternative locations are readily available on commercially reasonable terms, or at all, and if we are unable to relocate our officers in a timely manner, our operations may be interrupted.

Risks Relating to our Corporate Structure

If the PRC government deems that our contractual arrangements with our variable interest entity do not comply with PRC regulatory restrictions on foreign investment in the relevant industries, or if these regulations or the interpretation of existing regulations change in the future, we could be subject to severe penalties or be forced to relinquish our interests in those operations.

        Foreign ownership in entities that provide value-added telecommunication services is subject to restrictions under current PRC laws and regulations, unless certain exceptions are available. Specifically, foreign ownership of a value-added telecommunication service provider may not exceed 50%, except for the investment in the e-commerce operation business, a domestic multi-party communication business, an information storage and re-transmission business and a call center business, and the major foreign investors are required to have a record of good performance and operating experience in managing value-added telecommunications business.

        We are a Cayman Islands company and our PRC subsidiaries are considered foreign-invested enterprises. Accordingly, our PRC subsidiaries are not eligible to provide value-added telecommunication services or other internet related business that are subject to foreign ownership

42

Table of Contents

restriction under PRC laws. To ensure compliance with the PRC laws and regulations, we conducted our foreign investment-restricted business in China through our VIE and its subsidiaries, which currently hold the value-added telecommunication business license. Our WFOE has entered into a series of contractual arrangements with our VIE and its shareholders, respectively, which enable us to (i) exercise effective control over our VIE, (ii) receive substantially all of the economic benefits of our VIE, (iii) have the pledge right over the equity interests in our VIE as the pledgee; and (iv) have an exclusive option to purchase all or part of the equity interests in our VIE when and to the extent permitted by PRC law. As a result of these contractual arrangements, we have control over and are the primary beneficiary of our VIE and hence consolidate their financial results under U.S. GAAP. See "Corporate History and Structure" for further details.

        In the opinion of our PRC legal counsel, Han Kun Law Offices, (i) the ownership structures of our WFOE and our VIE in China, both currently and immediately after giving effect to this offering, are not in violation of provisions of applicable PRC laws and regulations currently in effect; and (ii) the contractual arrangements between our WFOE, our VIE and its shareholders governed by PRC law are not in violation of provisions of applicable PRC laws or regulations currently in effect, and valid and binding upon each party to such arrangements and enforceable against each party thereto in accordance with their terms and applicable PRC laws and regulations currently in effect. However, we have been further advised by our PRC legal counsel that there are substantial uncertainties regarding the interpretation and application of current and future PRC laws, regulations and rules. Thus, the PRC governmental authorities may take a view contrary to the opinion of our PRC legal counsel. It is uncertain whether any new PRC laws or regulations relating to variable interest entity structure will be adopted or if adopted, what they would provide. If we are or our VIE is found to be in violation of any existing or future PRC laws or regulations, or fail to obtain or maintain any of the required permits or approvals to operate our business, the relevant PRC governmental authorities would have broad discretion to take action in dealing with such violations or failures, including:

•

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



•

imposing fines on us;



•

confiscating any of our income that they deem to be obtained through illegal operations;



•

discontinuing or placing restrictions or onerous conditions on the operations of our VIE;



•

placing restrictions on our right to collect revenues;



•

shutting down our servers or blocking our app/websites; or



•

requiring us to restructure our ownership structure or operations;

        Any of these events could cause significant disruption to our business operations and severely damage our reputation, which would in turn have a material adverse effect on our financial condition and results of operations. If occurrences of any of these events results in our inability to direct the activities of our VIE in China that most significantly impact their economic performance and/or our failure to receive the economic benefits and residual returns from our VIE, and we are unable to restructure our ownership structure and operations in a satisfactory manner, we may not be able to consolidate the financial results of our VIE in our consolidated financial statements in accordance with U.S. GAAP.

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

        We have relied and expect to continue to rely on contractual arrangements with our VIE and its shareholders to conduct our operations in China. These contractual arrangements, however, may not be as effective as direct ownership in providing us with control over our VIE. For example, our VIE and

43

Table of Contents

its shareholders could breach their contractual arrangements with us by, among other things, failing to conduct the operations of our VIE in an acceptable manner or taking other actions that are detrimental to our interests.

        If we had direct ownership of our VIE in China, we would be able to exercise our rights as a shareholder to effect changes in the board of directors of our VIE, which in turn could implement changes, subject to any applicable fiduciary obligations, at the management and operational level. However, under the current contractual arrangements, we rely on the performance by our VIE and its shareholders of their obligations under the contracts to exercise control over our VIE. If any dispute relating to these contracts remains unresolved, we will have to enforce our rights under these contracts through the operations of PRC law and arbitration, litigation and other legal proceedings and therefore will be subject to uncertainties in the PRC legal system. See "—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."

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.

        If our VIE or its shareholders fail to perform their respective obligations under the contractual arrangements, we may have to incur substantial costs and expend additional resources to enforce such arrangements. We may also have to rely on legal remedies under PRC law, including seeking specific performance or injunctive relief, and contractual remedies, which we cannot assure you will be sufficient or effective under PRC law. For example, if the shareholders of our VIE were to refuse to transfer their equity interests in our VIE to us or our designee when we exercise the purchase option pursuant to these contractual arrangements, or if they were otherwise to act in bad faith toward us, then we may have to take legal actions to compel them to perform their contractual obligations.

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

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

        The shareholders of our VIE may have actual or potential conflicts of interest with us. These shareholders may breach, or cause our VIE to breach, or refuse to renew, the existing contractual arrangements we have with them and our VIE, which would have a material and adverse effect on our ability to effectively control our VIE and receive economic benefits from them. For example, the shareholders may be able to cause our agreements with our VIE to be performed in a manner adverse

44

Table of Contents

to us by, among other things, failing to remit payments due under the contractual arrangements to us on a timely basis. We cannot assure you that when conflicts of interest arise any or all of these shareholders will act in the best interests of our company or such conflicts will be resolved in our favor.

        Currently, we do not have any arrangements to address potential conflicts of interest between these shareholders and our company, except that we may invoke the right under the equity pledge agreements with the shareholders of the VIE to enforce the equity pledge in the case of the shareholders' breach of the contractual arrangements. For individuals who are also our directors and officers, we rely on them to abide by the laws of the Cayman Islands, which provide that directors and officers owe a fiduciary duty to the company that requires them to act in good faith and in what they believe to be the best interests of the company and not to use their position for personal gains. The shareholders of our VIE have executed powers of attorney to appoint our WFOE or a person designated by one of our WFOE to vote on their behalf and exercise voting rights as shareholders of our VIE. If we cannot resolve any conflict of interest or dispute between us and the shareholders of our VIE, we would have to rely on legal proceedings, which could result in disruption of our business and subject us to substantial uncertainty as to the outcome of any such legal proceedings.

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

Contractual arrangements we have entered into with our VIE may be subject to scrutiny by the PRC tax authorities. A finding that we owe additional taxes could negatively affect our financial condition and the value of your investment.

        Under applicable PRC laws and regulations, arrangements and transactions among related parties may be subject to audit or challenge by the PRC tax authorities. We could face material and adverse tax consequences if the PRC tax authorities determine that the contractual arrangements in relation to our VIE 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 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 their tax liabilities without reducing our PRC subsidiary's tax expense. In addition, the PRC tax authorities may impose late payment fees and other administrative sanctions 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 they are required to pay late payment fees and other penalties.

45

Table of Contents

We may lose the ability to use and benefit from assets held by our VIE that are material or supplementary to the operation of our business if either of our VIE goes bankrupt or becomes subject to dissolution or liquidation proceedings.

        As part of our contractual arrangements with our VIE, our VIE may currently and in the future hold certain assets that are material or supplementary to the operation of our business. If our VIE goes bankrupt and all or part of its assets become subject to liens or rights of creditors, we may be unable to continue some or all of our business activities we currently conduct through the contractual arrangement, which could materially and adversely affect our business, financial condition and results of operations. Under the contractual arrangements, our VIE may not, in any manner, sell, transfer, mortgage or dispose of their assets or legal or beneficial interests in the business without our prior consent. If our VIE undergoes voluntary or involuntary liquidation proceedings, unrelated creditors may claim rights to some or all of these assets, thereby hindering our ability to operate part of our business, which could materially and adversely affect our business, financial condition and results of operations.

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

        The value-added telecommunications services that we conduct through our VIE and its subsidiaries are subject to foreign investment restrictions set forth in the Special Management Measures (Negative List) for the Access of Foreign Investment issued by the Ministry of Commerce, or the MOFCOM, and the National Development and Reform Commission, or the NDRC, effective July 2020.

        On March 15, 2019, the National People's Congress promulgated the Foreign Investment Law, or the Foreign Investment Law (2019), which became effective on January 1, 2020 and replaced the Sino-Foreign Equity Joint Venture Enterprise Law, the Sino-Foreign Cooperative Joint Venture Enterprise Law and the Wholly Foreign-Owned Enterprise Law to become the legal foundation for foreign investment in the PRC. Since it is relatively new, uncertainties still exist in relation to its interpretation and implementation. For instance, under the Foreign Investment Law (2019), "foreign investment" refers to the investment activities directly or indirectly conducted by foreign individuals, enterprises or other entities in China. Though it does not explicitly classify contractual arrangements as a form of foreign investment, there is no assurance that foreign investment via contractual arrangements would not be interpreted as a type of indirect foreign investment activities in the future. In addition, the definition of foreign investment contains a catch-all provision which includes investments made by foreign investors through means stipulated in laws, administrative regulations or provisions of the State Council. Therefore, it still leaves leeway for future laws, administrative regulations or provisions promulgated by the State Council to provide for contractual arrangements as a form of foreign investment. In any of these cases, it will be uncertain whether our contractual arrangements will be deemed to be in violation of the market access requirements for foreign investment under the PRC laws and regulations. If further actions shall be taken under future laws, administrative regulations or provisions of the State Council, we may face substantial uncertainties as to whether we can complete such actions. Failure to do so could materially and adversely affect our current corporate structure, corporate governance and operations.

We face risks associated with the Restructuring and the subsequent operation of our business.

        We undertook a Restructuring in order to operate our standalone business in China. For more details, see "Corporate History and Structure—Restructuring" We expect the Restructuring to enhance and strength our position as a dominant e-vapor brand in China. However, there can be no assurance that the Restructuring will deliver such benefits. Our parent company Relx Inc. historically operated production and sale of e-vapor products business in markets both in and outside of China. Going

forward, we will operate our business in China under the brand of "Relx," whereas our parent company Relx Inc. will continue to operate the product and sale of e-vapor products business in markets outside of China under the same brand. We have entered into an intellectual property license agreement with our parent company Relx Inc. relating to our trademarks and certain other proprietary rights for overseas markets. See "—Risks Relating to Our Business and Industry—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 the value of our brand as our licensee." However, the overseas markets business may be perceived to be a part of our business, which could subject us to reputational and regulatory risks. Any negative developments with respect to the overseas markets business and Relx Inc. may materially and adversely affect our business and brand.

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.

        We expect that our revenues will be derived in China and most of our operations will continue to be conducted in China. Accordingly, our results of operations, financial condition and prospects are influenced by economic, political and legal developments in China. China's economy differs from the economies of most developed countries in many respects, including with respect to the amount of government involvement, level of development, growth rate, control of foreign exchange and allocation of resources. Although the PRC 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. The PRC government also exercises significant control over China's economic growth through strategically allocating resources, controlling the payment of foreign currency-denominated obligations, setting monetary policy and providing preferential treatment to particular industries or companies. While the PRC economy has experienced significant growth over the past decades, that growth has been uneven across different regions and between economic sectors and may not continue, as evidenced by the slowing of the growth of the Chinese economy since 2012. 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, leading to reduction in demand for our services and solutions and adversely affect our competitive position.

        The Chinese government has implemented various measures to encourage economic growth and guide the allocation of resources. Some of these measures may benefit the overall Chinese economy, but may have a negative effect on us. 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 results of operations.

Uncertainties with respect to the PRC legal system could materially and 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. The overall effect of legislation over the past three decades 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. Since these laws and regulations are relatively new and the PRC legal system continues to rapidly evolve, the interpretations of many laws, regulations and rules may not be uniform and enforcement of these laws, regulations and rules involves

47

Table of Contents

uncertainties. These uncertainties may affect our judgment on the relevance of legal requirements and our ability to enforce our contractual rights or tort claims. Besides, the PRC is geographically large and divided into various provinces and municipalities and, as such, different laws, rules, regulations and policies may have different and varying applications and interpretations in different parts of the PRC. Legislation or regulations, particularly in local applications, may be enacted without sufficient prior notice or announcement to the public. 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. Agreements that are governed by PRC laws may be more difficult to enforce by legal or arbitral proceedings in the PRC than that in other countries with different legal systems. In addition, any administrative and court proceedings in China may be protracted, resulting in substantial costs and diversion of resources and management attention.

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 rely on dividends and other distributions on equity from our PRC subsidiaries for our cash requirements, including the funds necessary to pay dividends and other cash distributions to our shareholders and service any debt we may incur. Current PRC regulations permit our PRC subsidiaries to pay dividends to us only out of their accumulated after-tax profits upon satisfaction of relevant statutory conditions and procedures, if any, determined in accordance with Chinese accounting standards and regulations. In addition, each of our PRC subsidiaries is required to set aside at least 10% of its after-tax profits each year, if any, to fund certain reserve funds until the total amount set aside reaches 50% of its registered capital. Additionally, if our PRC subsidiaries incur debt on their own behalf in the future, the instruments governing their debt may restrict their ability to pay dividends or make other distributions to us. Furthermore, the PRC tax authorities may require our subsidiaries to adjust their taxable income under the contractual arrangements they currently have in place with our VIE in a manner that would materially and adversely affect their ability to pay dividends and other distributions 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 businesses, pay dividends or otherwise fund and conduct our business.

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 laws, legal documents for corporate transactions 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 the relevant branch of the SAMR. 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 which will then 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 secure 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 any of our subsidiaries or 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. We may have to take corporate or legal action, which could involve significant time and resources to resolve and divert management from our operations. In addition, the affected entity may not be able to recover corporate assets that are sold or transferred out of our control in the event of such a misappropriation if a transferee relies on the apparent authority of the representative and acts in good faith.

PRC regulation of loans to and direct investment in PRC entities by offshore holding companies may delay us from using the proceeds of this offering to make loans or additional capital contributions to our PRC subsidiaries and to make loans to our VIE, 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, as well as any loans we provide to our VIE, 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 registration with SAMR or its local counterpart and registration with a local bank authorized by the State Administration of Foreign Exchange, or the SAFE. In addition, (i) any foreign loan procured by our PRC subsidiaries is required to be registered with the SAFE or its local branches and (ii) any of our PRC subsidiaries may not procure loans which exceed the difference between its total investment amount and registered capital or, as an alternative, only procure loans subject to the calculation approach and limitation as provided by the People's Bank of China. Additionally, any medium or long-term loans 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 obtain these government approvals or complete such registrations in a timely manner, or at all, with respect to future capital contributions or foreign loans by us to our PRC subsidiaries or loans by us to our VIE. If we fail to receive such approvals or complete such registration or filing, our ability to use the proceeds of this offering to capitalize our PRC operations may be negatively affected, which could adversely affect our liquidity and our ability to fund and expand our business.

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 Renminbi into foreign currencies and, in certain cases, the remittance of currency out of China. We receive our revenues primarily 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 the SAFE by complying with certain procedural requirements. Specifically, under the existing foreign exchange restrictions, without prior approval of the 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 our ADSs.

China's M&A Rules and certain other PRC regulations establish complex procedures for certain acquisitions of PRC companies, which could make it more difficult for us to pursue growth through acquisitions in China.

        A number of PRC laws and regulations have established procedures and requirements that could make merger and acquisition activities in China by foreign investors more time consuming and complex. In addition to the Anti-monopoly Law itself, these include the Regulations on Mergers and Acquisitions of Domestic Enterprises by Foreign Investors, or the M&A Rules, adopted by six PRC

49

Table of Contents

regulatory agencies in 2006 and amended in 2009, the Rules of the Ministry of Commerce on Implementation of Security Review System of Mergers and Acquisitions of Domestic Enterprises by Foreign Investors promulgated in 2011, and the Measures for the Security Review of Foreign Investment promulgated by NDRC and the Ministry of Commerce in December 2020 and will come into force on January 18, 2021. These laws and regulations impose requirements in some instances that the PRC Ministry of Commerce be notified in advance of any change-of-control transaction in which a foreign investor takes control of a PRC domestic enterprise. In addition, pursuant to relevant anti-monopoly laws and regulations, the SAMR should be notified in advance of any concentration of undertaking if certain thresholds are triggered. In light of the uncertainties relating to the interpretation, implementation and enforcement of the anti-monopoly laws and regulations of the PRC, we cannot assure you that the anti-monopoly law enforcement agency will not deem our future acquisitions or investments to have triggered filing requirement for anti-monopoly review. Moreover, mergers and acquisitions by foreign investors that raise "national defense and security" concerns and mergers and acquisitions through which foreign investors may acquire de facto control over domestic enterprises that raise "national security" concerns are subject to strict review by NDRC and the PRC Ministry of Commerce, and prohibit any attempt to bypass a security review, including by structuring the transaction through a proxy or contractual control arrangement. In the future, we may grow our business by acquiring complementary businesses. Complying with the requirements of the relevant regulations to complete such transactions could be time consuming, and any required approval processes, including clearance from the SAMR and approval from the PRC Ministry of Commerce, 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, the 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, which requires PRC residents (including PRC individuals and PRC corporate entities) to register with the SAFE or its local branches in connection with their establishment or control of an offshore entity established for the purpose of overseas investment or financing with such PRC residents' legally owned assets or equity interests in domestic enterprises or offshore assets or interests. 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. In addition, such PRC residents must update their SAFE registrations when the offshore special purpose vehicle undergoes material events relating to any change of basic information (including change of such PRC citizens or residents, name and operation term), increases or decreases in investment amount, transfers or exchanges of shares, or mergers or divisions. According to the Circular on Further Simplifying and Improving Foreign Exchange Administration Policy on Direct Investment, which became effective on June 1, 2015, 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 the SAFE. The term "control" under SAFE Circular 37 is broadly defined as the operation rights, beneficiary rights or decision-making rights acquired by PRC residents in the offshore special purpose vehicles, or SPVs, by means of acquisition, trust, proxy, voting rights, repurchase, convertible bonds or other arrangements. If any PRC shareholder of such SPVs fails to make the required registration or to update the previously filed registration, the subsidiary of such SPVs in China may be prohibited from distributing theirs profits or the proceeds from any capital reduction, share transfer or liquidation to the SPVs, and the SPVs may also be prohibited from making additional capital contributions into their subsidiary in China.

        We have notified all individuals or entities who directly hold shares in our Cayman Islands holding company and are known to us as PRC residents to complete or update the foreign exchange registrations. However, we may not be informed of the identities of all the PRC individuals or entities holding direct or indirect interest in our company, nor can we compel our beneficial owners to comply with the SAFE registration requirements. As a result, we cannot assure you that all of our shareholders or beneficial owners who are PRC residents have complied with, and will in the future make, obtain or update any applicable registrations or approvals required by SAFE regulations. In addition, concerning the uncertainty of the application of SAFE Circular 37, some of our current beneficial owners who are PRC residents are in the process of updating their SAFE registrations to address the changes of their offshore interest. Failure by such shareholders or beneficial owners to comply with SAFE regulations, or failure by us to amend the foreign exchange registrations of our PRC subsidiaries, could subject us to fines or legal sanctions, restrict our overseas or cross-border investment activities, limit our PRC subsidiaries' ability to make distributions or pay dividends to us or affect our ownership structure, which 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, the 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 the SAFE through a domestic qualified agent, which could be the PRC subsidiaries of such overseas-listed company, and complete certain other procedures. See "Regulation—Regulations on Foreign Exchange and Dividend Distribution—Regulations on Foreign Exchange Registration of Overseas Investment by PRC Residents." 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 or will be granted incentive shares or options are subject to these regulations. Failure to complete the SAFE registrations may subject us or them to fines and legal sanctions. We also face regulatory uncertainties that could restrict our ability to adopt additional incentive plans for our directors, executive officers and employees under PRC law.

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 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 the SAT, issued a circular, known as SAT Circular 82, which provides certain specific criteria for determining whether the "de facto management body" of a PRC-controlled enterprise that is incorporated offshore is located in China. Although this circular only applies to offshore enterprises controlled by PRC enterprises or PRC enterprise groups, not those controlled by PRC individuals or foreigners, the criteria set forth in the circular may reflect 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

51

Table of Contents

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 none of our entities outside of China is a PRC resident enterprise for PRC tax purposes. However, the tax resident status of an enterprise is subject to determination by the PRC tax authorities and uncertainties remain with respect to the interpretation of the term "de facto management body." If the PRC tax authorities determine that we are a PRC resident enterprise for enterprise income tax purposes, we will be subject to PRC enterprise income on our worldwide income at the rate of 25% and we will be required to withhold a 10% withholding tax from dividends we pay to our shareholders that are non-resident enterprises, including the holders of our ADSs. In addition, gains realized on the sale or other disposition of our ADSs or Class A ordinary shares may be subject to PRC tax, at a rate of 10% in the case of non-PRC enterprises or 20% in the case of non-PRC individuals (in each case, subject to the clauses of any applicable tax treaty), if such gains are deemed to be from the PRC. 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.

We face uncertainty with respect to indirect transfers of equity interests in PRC resident enterprises by their non-PRC holding companies, which may have a material adverse effect on our financial condition and results of operations.

        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 provides certain criteria on how to assess reasonable commercial purposes and has introduced safe harbors for internal group restructurings and the purchase and sale of equity through a public securities market. SAT 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. 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. 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 is obligated to pay for the transfer is obligated to withhold the applicable taxes, currently at a rate of 10% for the transfer of equity interests in a PRC resident enterprise.

        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. 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

52

Table of Contents

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 establish that we and our non-PRC resident investors should not be taxed under these circulars, which may have a material adverse effect on our financial condition and results of operations.

You may experience difficulties in effecting service of legal process, enforcing foreign judgments or bringing actions in China against us or our management named in this 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 all are PRC nationals. 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. Even if you are successful in bringing an action of this kind, PRC laws 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 PRC laws, see "Enforceability of Civil Liabilities."

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

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

Failure to obtain or maintain any of the preferential tax treatments and government subsidies or imposition of any additional taxes and surcharges could adversely affect our financial condition and results of operations.

        Under the PRC Enterprise Income Tax Law and its implementation rules, the statutory enterprise income tax rate is 25%, but certain "software enterprise" and "high and new technology enterprises" are qualified for a preferential enterprise income tax rates subject to certain qualification criteria. A "high and new technology enterprise," which is reassessed every three years, is entitled to favorable income tax rate of 15%. In December 2020, Shenzhen Wuxin Technology Co., Ltd., or Shenzhen Wuxin, obtained qualification as a "high and new technology enterprise" and is entitled to enjoy a preferential income tax rate of 15% for the tax filing of fiscal years from 2020 to 2022. However, if it fails to maintain its qualified status, experiences any increase in the enterprise income tax rate, or faces any discontinuation, retroactive or future reduction or refund of any of the preferential tax treatments currently enjoyed, our business, financial condition and results of operations could be materially and adversely affected. In addition, Ningbo Wuxin Information Technology Co., Ltd., or Ningbo Wuxin,

53

Table of Contents

entered into preferential tax arrangement with local government that entitles it to certain portion of tax return upon satisfaction of certain tax-related condition.

        Further, in the ordinary course of our business, we are subject to complex income tax and other tax regulations, and significant judgment is required in the determination of a provision for income taxes. Although we believe our tax provisions are reasonable, if the PRC tax authorities successfully challenge our position and we are required to pay tax, interest and penalties in excess of our tax provisions, our financial condition and results of operations would be materially and adversely affected.

The approval of the China Securities Regulatory Commission, or CSRC, may be required in connection with this offering, and, if required, we cannot predict whether we will be able to obtain such approval.

        The M&A Rules require an overseas special purpose vehicle formed for listing purposes through acquisitions of PRC domestic companies and controlled by PRC companies or individuals to obtain the approval of the CSRC prior to the listing and trading of such special purpose vehicle's securities on an overseas stock exchange. The interpretation and application of the regulations remain unclear, and this offering may ultimately require approval from the CSRC. If the CSRC approval is required, it is uncertain how long it will take us to obtain such approval and any failure to obtain or delay in obtaining the approval for this offering would subject us to sanctions imposed by the CSRC and other PRC regulatory agencies, which could include fines and penalties on our operations in China, restrictions or limitations on our ability to pay dividends outside of China, and other forms of sanctions that may materially and adversely affect our business, results of operations and financial condition.

        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 our ADSs on the New York Stock Exchange. However, 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 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.

The audit report included in this prospectus is prepared by an auditor who is not inspected by the U.S. Public Company Accounting Oversight Board, or the PCAOB, and as such, our investors are deprived of the benefits of such inspection. In addition, the adoption of any rules, legislations or other efforts to increase U.S. regulatory access to audit information could cause uncertainty and our securities could be delisted or prohibited from being traded "over-the-counter" if we are unable to meet the PCAOB inspection requirement in time.

        Our auditor, the independent registered public accounting firm that issues the audit report included elsewhere in this prospectus, as an auditor of companies that are traded publicly in the United States and a firm registered with the PCAOB is subject to laws in the United States pursuant to which the PCAOB conducts regular inspections to assess its compliance with the applicable professional

54

Table of Contents

standards. Since our auditor is located in China, a jurisdiction where the PCAOB has been unable to conduct inspections without the approval of the Chinese authorities, our auditor is currently not inspected by the PCAOB.

        In May 2013, the PCAOB announced that it had entered into a Memorandum of Understanding on Enforcement Cooperation with the CSRC, and the PRC Ministry of Finance, which establishes a cooperative framework between the parties for the production and exchange of audit documents relevant to investigations undertaken by the PCAOB, the CSRC or the PRC Ministry of Finance in the United States and the PRC, respectively. The PCAOB continues to be in discussions with the CSRC, and the PRC Ministry of Finance to permit joint inspections in the PRC of audit firms that are registered with PCAOB and audit Chinese companies that trade on U.S. exchanges.

        On December 7, 2018, the SEC and the PCAOB issued a joint statement highlighting continued challenges faced by the U.S. regulators in their oversight of financial statement audits of U.S.-listed companies with significant operations in China.

        On April 21, 2020, the SEC and the PCAOB issued another joint statement reiterating the greater risk that disclosures will be insufficient in many emerging markets, including China, compared to those made by U.S. domestic companies. In discussing the specific issues related to the greater risk, the statement again highlights the PCAOB's inability to inspect audit work paper and practices of accounting firms in China with respect to their audit work of U.S. reporting companies.

        On June 4, 2020, the U.S. President issued a memorandum ordering the President's Working Group on Financial Markets, or the PWG, to submit a report to the President within 60 days of the memorandum that includes recommendations for actions that can be taken by the executive branch and by the SEC or PCAOB on Chinese companies listed on U.S. stock exchanges and their audit firms, in an effort to protect investors in the U.S. On August 6, 2020, the PWG released a report recommending that the SEC take steps to implement the five recommendations outlined in the report. In particular, to address companies from jurisdictions that do not provide the PCAOB with sufficient access to fulfill its statutory mandate, or NCJs, the PWG recommends enhanced listing standards on U.S. stock exchanges. This would require, as a condition to initial and continued exchange listing, PCAOB access to work papers of the principal audit firm for the audit of the listed company. Companies unable to satisfy this standard as a result of governmental restrictions on access to audit work papers and practices in NCJs may satisfy this standard by providing a co-audit from an audit firm with comparable resources and experience where the PCAOB determines it has sufficient access to audit work papers and practices to conduct an appropriate inspection of the co-audit firm. The report permits the new listing standards to provide for a transition period until January 1, 2022 for listed companies, but would apply immediately to new listings once the necessary rulemakings and/or standard-setting are effective. If we fail to meet the new listing standards before the deadline specified thereunder due to factors beyond our control, we could face possible de-listing from the New York Stock Exchange, deregistration from the SEC and/or other risks, which may materially and adversely affect the market price and liquidity of our ADSs, or effectively terminate, our ADS trading in the United States. There were recent media reports about the SEC's proposed rulemaking in this regard. It is uncertain whether the PWG recommendations will be adopted, in whole or in part, and the impact of any new rule on us cannot be estimated at this time.

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

inspections, which could cause investors and potential investors in our stock to lose confidence in our audit procedures and reported financial information and the quality of our financial statements.

        On December 18, 2020, the Holding Foreign Companies Accountable Act, or the Act, was enacted. In essence, the Act requires the SEC to prohibit securities of any foreign companies from being listed on U.S. securities exchanges or traded "over-the-counter" if a company retains a foreign accounting firm that cannot be inspected by the PCAOB for three consecutive years, beginning in 2021. The enactment of the Act and any additional rulemaking efforts to increase U.S. regulatory access to audit information in China could cause investor uncertainty for affected SEC registrants, including us, the market price of our ADSs could be materially adversely affected, and our securities could be delisted or prohibited from being traded "over-the-counter" if we are unable to meet the PCAOB inspection requirement in time.

Proceedings instituted by the SEC against certain PRC-based 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.

        In December 2012, the SEC instituted administrative proceedings against the Big Four PRC-based accounting firms in China, including our independent registered public accounting firm, alleging that these firms had violated U.S. securities laws and the SEC's rules and regulations thereunder by failing to provide to the SEC the firms' audit work papers with respect to certain other PRC-based companies that are publicly traded in the United States.

        On January 22, 2014, the initial administrative law judge presiding over the matter rendered an initial decision that each of the firms had violated the SEC's rules of practice by failing to produce audit papers and other documents to the SEC. The initial decision censured each of the firms and barred them from practicing before the SEC for a period of six months.

        On February 6, 2015, each of the four PRC-based accounting firms agreed to a censure and to pay a fine to the SEC to settle the dispute and avoid suspension of their ability to practice before the SEC and to audit US-listed companies. The settlement required the firms to follow detailed procedures and to seek to provide the SEC with access to Chinese firms' audit documents via the CSRC. Under the terms of the settlement, the underlying proceeding against the four PRC-based accounting firms was deemed dismissed with prejudice four years after entry of the settlement. The four-year mark occurred on February 6, 2019. While we cannot predict if the SEC will further challenge the four PRC-based accounting firms' compliance with U.S. law in connection with U.S. regulatory requests for audit work papers or if the results of such a challenge would result in the SEC imposing penalties such as suspensions, if the accounting firms are subject to additional remedial measures, our ability to file our financial statements in compliance with SEC requirements could be impacted. A determination that we have not timely filed financial statements in compliance with SEC requirements could ultimately lead to our delisting from the New York Stock Exchange or deregistration from the SEC, or both, which would substantially reduce or effectively terminate the trading of our ADSs in the United States.

        In the event that the SEC restarts the administrative proceedings, depending upon the final outcome, listed companies in the United States with major PRC operations may find it difficult or impossible to retain auditors in respect of their operations in the PRC, which could result in financial statements being determined not to be in compliance with the requirements of the Exchange Act, including possible delisting. Moreover, any negative news about any such future proceedings against these audit firms may cause investor uncertainty regarding China-based, U.S.-listed companies and the market price of our ADSs may be adversely affected.

        If our independent registered public accounting firm was denied, even temporarily, the ability to practice before the SEC and we were unable to timely find another registered public accounting firm to audit and issue an opinion on our financial statements, our financial statements could be determined to

56

be not in compliance with the requirements of the Exchange Act. Such a determination could ultimately lead to the delisting of the ADSs or deregistration from the SEC, or both, which would substantially reduce or effectively terminate the trading of the ADSs in the United States.

The tension in international trade and rising political tension, particularly between U.S. and China, may adversely impact our business, financial condition, and results of operations.

        Although cross-border business may not be an area of our focus, if we plan to expand our business internationally in the future, any unfavorable government policies on international trade, such as capital controls or tariffs, may affect the demand for our products and services, impact our competitive position, or prevent us from being able to conduct business in certain countries. If any new tariffs, legislation, or regulations are implemented, or if existing trade agreements are renegotiated, such changes could adversely affect our business, financial condition, and results of operations. Recently, there have been heightened tensions in international economic relations, such as the one between the United States and China. The U.S. government has recently imposed, and has recently proposed to impose additional, new, or higher tariffs on certain products imported from China to penalize China for what it characterizes as unfair trade practices. China has responded by imposing, and proposing to impose additional, new, or higher tariffs on certain products imported from the United States. Following mutual retaliatory actions for months, on January 15, 2020, the United States and China entered into the Economic and Trade Agreement Between the United States of America and the People's Republic of China as a phase one trade deal, effective on February 14, 2020.

        Although the direct impact of the current international trade tension, and any escalation of such tension, on the e-vapor industry in China is uncertain, the negative impact on general, economic, political and social conditions may adversely impact our business, financial condition and results of operations.

        In addition, political tensions between the United States and China have escalated due to, among other things, trade disputes, the COVID-19 outbreak, sanctions imposed by the U.S. Department of Treasury on certain officials of the Hong Kong Special Administrative Region and the central government of the PRC and the executive orders issued by U.S. President Donald J. Trump in August 2020 that prohibit certain transactions with certain Chinese companies and their applications. Rising political tensions could reduce levels of trades, investments, technological exchanges and other economic activities between the two major economies, which would have a material adverse effect on global economic conditions and the stability of global financial markets. Any of these factors could have a material adverse effect on our business, prospects, financial condition and results of operations.

General Risks Relating to Our ADSs and This Offering

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

        Our ADSs have been approved for listing on the New York Stock Exchange. Prior to the completion of this offering, there has been no public market for our ADSs or our Class A ordinary shares, and we cannot assure you that a liquid public market for our ADSs will develop. If an active public market for our ADSs does not develop following the completion of this offering, the market price and liquidity of our ADSs may be materially and adversely affected. The initial public offering price for our ADSs is determined by negotiation between us and the underwriters based upon several factors, and the trading price of our ADSs after this offering could decline below the initial public offering price. As a result, investors in our securities may experience a significant decrease in the value of their ADSs.

57

Table of Contents

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:

•

actual or anticipated fluctuations in our quarterly results of operations;



•

variations in our revenues, earnings, cash flows;



•

fluctuations in operating metrics;



•

regulatory developments affecting us or our industry;



•

detrimental negative publicity about us, our competitors or our industry;



•

announcements of new products and services and expansions by us or our competitors;



•

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



•

changes in financial estimates by securities analysts;



•

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. The securities of some China-based companies that have listed their securities in the United States have experienced significant volatility since their initial public offerings in recent years, including, in some cases, substantial declines in the trading prices of their securities. The trading performances of these companies' securities after their offerings may affect the attitudes of investors towards Chinese companies listed in the United States in general, which consequently may impact the trading performance of our ADSs, regardless of our actual operating performance. In addition, any negative news or perceptions about inadequate corporate governance practices or fraudulent accounting, corporate structure or other matters of other Chinese companies may also negatively affect the attitudes of investors towards Chinese companies in general, including us, regardless of whether we have engaged in any inappropriate activities. In particular, the global financial crisis, the ensuing economic recessions and deterioration in the credit market in many countries have contributed and may continue to contribute to extreme volatility in the global stock markets. These broad market and industry fluctuations may adversely affect the market price of our ADSs. Volatility or a lack of positive performance in our ADS price may also adversely affect our ability to retain key employees, most of whom have been granted options or other equity incentives.

        In the past, shareholders of public companies have often brought securities class action suits against 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.

We are an emerging growth company within the meaning of the Securities Act and may take advantage of certain reduced reporting requirements.

        We are an "emerging growth company," as defined in the JOBS Act, and we may take advantage of certain exemptions from requirements applicable to other public companies that are not emerging growth companies including, most significantly, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002 for so long as we remain an emerging growth company. As a result, if we elect not to comply with such auditor attestation requirements, our investors may not have access to certain information they may deem important.

        The JOBS Act also provides that an emerging growth company does not need to comply with any new or revised financial accounting standards until such date that a private company is otherwise required to comply with such new or revised accounting standards. This election allows us to delay the adoption of new or revised accounting standards that have different effective dates for public and private companies until those standards apply to private companies, and as a result of this election our financial statements may not be comparable to those of companies that comply with public company effective dates, including other emerging growth companies that have not made this election.

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.

        Immediately prior to the completion of this offering, we expect to create a dual-class share structure such that our ordinary shares will consist of Class A ordinary shares and Class B ordinary shares. In respect of matters requiring the votes of shareholders, holders of Class A ordinary shares will be entitled to one vote per share, while holders of Class B ordinary shares will be entitled to ten votes per share based on our proposed dual-class share structure. We will sell Class A ordinary shares represented by our ADSs in this offering. Each Class B ordinary share is convertible into one Class A ordinary share at any time by the holder thereof, while Class A ordinary shares are not convertible into Class B ordinary shares under any circumstances. Any number of Class B ordinary shares held by a holder thereof will be automatically and immediately converted into an equal number of Class A ordinary shares upon the occurrence of (i) any direct or indirect sale, transfer, assignment or disposition of such number of Class B ordinary shares by the holder thereof or the direct or indirect transfer or assignment of the voting power attached to such number of Class B ordinary shares through voting proxy or otherwise to any person that is not Relx Holdings Limited, Ms. Ying (Kate) Wang or an entity controlled by her, or (ii) the direct or indirect sale, transfer, assignment or disposition of a majority of the issued and outstanding voting securities of, or the direct or indirect transfer or assignment of the voting power attached to such voting securities through voting proxy or otherwise, or the direct or indirect sale, transfer, assignment or disposition of all or substantially all of the assets of, a holder of Class B ordinary shares that is an entity to any person that is not Relx Holdings Limited, Ms. Ying (Kate) Wang or an entity controlled by her.

        Immediately prior to the completion of this offering, 1,436,815,570 ordinary shares held by Relx Inc. will be re-designated as Class B ordinary shares. Relx Inc. will beneficially own approximately 99.2% of the aggregate voting power of our company immediately after the completion of this offering due to the disparate voting powers associated with our dual-class share structure, assuming the underwriters do not exercise their over-allotment option. We expect that, within six months following this offering, the existing shareholders of Relx Inc. would become our shareholders. Upon the completion of this shareholding change, Relx Holdings Limited, a British Virgin Islands company controlled by Ms. Ying (Kate) Wang, the chairperson of our board of directors and chief executive officer, will hold Class B ordinary shares and beneficially own approximately 86.9% of the aggregate voting power of our company. As a result of the dual-class share structure and the concentration of ownership, holders of our Class B ordinary shares will have considerable influence over matters such as

59

Table of Contents

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

Until Relx Inc. distributes shares in our company to its existing shareholders, Relx Inc. will have considerable influence over us and our corporate matters.

        Upon completion of this offering, assuming the underwriters do not exercise their over-allotment option, and prior to the distribution of shares in our company to its shareholders, Relx Inc. will hold all of our then outstanding Class B ordinary shares, representing 99.2% of our total voting power, assuming that the underwriters do not exercise their over-allotment option, and will remain our controlling shareholder. Relx Inc. will then have considerable power to control actions that require shareholder approval under Cayman Islands law, such as electing directors, approving material mergers, acquisitions or other business combination transactions and amending our memorandum and articles of association. This control will limit your ability to influence corporate matters and may prevent transactions that would be beneficial to you, including discouraging others from pursuing any potential merger, takeover or other change of control transactions, which could have the effect of depriving the holders of our Class A ordinary shares and our ADSs of the opportunity to sell their shares at a premium over the prevailing market price. Furthermore, if Relx Inc. is acquired or otherwise undergoes a change of control, any acquirer or successor will be entitled to exercise the voting control and contractual rights of Relx Inc., and may do so in a manner that could vary significantly from that of Relx Inc.

Our dual-class voting structure may render the ADSs representing our Class A ordinary shares ineligible for inclusion in certain stock market indices, and thus adversely affect the trading price and liquidity of the ADSs.

        We cannot predict whether our dual-class share structure with different voting rights will result in a lower or more volatile market price of the ADSs, adverse publicity, or other adverse consequences. Certain index providers have announced restrictions on including companies with multi-class share structures in certain of their indices. For example, S&P Dow Jones and FTSE Russell have changed their eligibility criteria for inclusion of shares of public companies on certain indices, including the S&P 500, to exclude companies with multiple classes of shares and companies whose public shareholders hold no more than 5% of total voting power from being added to such indices. As a result, our dual-class voting structure may prevent the inclusion of the ADSs representing our Class A ordinary shares in such indices, which could adversely affect the trading price and liquidity of the ADSs representing our Class A ordinary shares. In addition, several shareholder advisory firms have announced their opposition to the use of multiple class structure and our dual-class structure may cause shareholder advisory firms to publish negative commentary about our corporate governance, in which case the market price and liquidity of the ADSs could be adversely affected.

We will be a "controlled company" within the meaning of the NYSE Listed Company Manual.

        Our company is currently 100% owned by Relx Inc. We expect that, within six months following this offering, the existing shareholders of Relx Inc. would become our shareholders. Immediately following the completion of this offering, we will be a "controlled company" as defined under the

60

Table of Contents

NYSE Listed Company Manual because Relx Inc. will beneficially own all of our then outstanding Class B ordinary share, representing more than 50% of our total voting power. We currently expect that we will continue to be a "controlled company" after the completion of the abovementioned shareholding change as Relx Holdings Limited, a British Virgin Islands company controlled by Ms. Ying (Kate) Wang, the chairperson of our board of directors and chief executive officer, will hold all of our then outstanding Class B ordinary shares, representing more than 50% of our total voting power. For so long as we remain a controlled company under that definition, we are permitted to elect to rely, and will rely, on certain exemptions from corporate governance rules, including an exemption from the rule that a majority of our board of directors must be independent directors. Currently, we plan to rely on the exemption with respect to the requirement that a majority of the board of directors consist of independent directors. As a result, you will not have the same protection afforded to shareholders of companies that are subject to these corporate governance requirements.

If securities or industry analysts cease to publish research or reports about our business, or if they adversely change their recommendations regarding the ADSs, the market price for the ADSs and trading volume could decline.

        The trading market for the ADSs will be influenced by research or reports that industry or securities analysts publish about our business. If one or more analysts who cover us downgrade the ADSs, the market price for the ADSs would likely decline. If one or more of these analysts cease to cover us or fail to regularly publish reports on us, we could lose visibility in the financial markets, which, in turn, could cause the market price or trading volume for the ADSs to decline.

We currently do not expect to pay dividends in the foreseeable future after this offering and you must rely on price appreciation of our ADSs for return on your investment.

        We currently intend to retain most, if not all, of our available funds and any future earnings after this offering to fund the development and growth of our business. As a result, we do not expect to pay any cash dividends in the foreseeable future. Therefore, you should not rely on an investment in our ADSs as a source for any future dividend income.

        Our board of directors has complete discretion as to whether to distribute dividends, subject to certain requirements of Cayman Islands law. In addition, our shareholders may by ordinary resolution declare a dividend, but no dividend may exceed the amount recommended by our directors. Under Cayman Islands law, a Cayman Islands company may pay a dividend out of either profit or share premium account, provided that in no circumstances may a dividend be paid if this would result in the company being unable to pay its debts as they fall due in the ordinary course of business. Even if our board of directors decides to declare and pay dividends, the timing, amount and form of future dividends, if any, will depend on our future results of operations and cash flows, our capital requirements and surplus, the amount of distributions, if any, received by us from our subsidiaries, our financial condition, contractual restrictions and other factors deemed relevant by our board of directors. Accordingly, the return on your investment in our ADSs will likely depend entirely upon any future price appreciation of our ADSs. There is no guarantee that our ADSs will appreciate in value after this offering or even maintain the price at which you purchased the ADSs. You may not realize a return on your investment in our ADSs and you may even lose your entire investment in our ADSs.

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

        If you purchase ADSs in this offering, you will pay more for your ADSs than the amount paid by our existing shareholders for their Class A ordinary shares on a per ADS basis. As a result, you will experience immediate and substantial dilution, representing the difference between the initial public offering price of per ADS, and our adjusted net tangible book value per ADS, after giving effect to our

61

Table of Contents

sale of the ADSs offered in this offering. In addition, you may experience further dilution in connection with the issuance of Class A ordinary shares upon the exercise or vesting, as the case may be, of our share incentive awards. See "Dilution" for a more complete description of how the value of your investment in the ADSs will be diluted upon completion of this offering.

We have not determined a specific use for a portion of the net proceeds from this offering and we may use these proceeds in ways with which you may not agree.

        We have not determined a specific use for a portion of the net proceeds of this offering, and our management will have considerable discretion in deciding how to apply these proceeds. You will not have the opportunity to assess whether the proceeds are being used appropriately before you make your investment decision. You must rely on the judgment of our management regarding the application of the net proceeds of this offering. We cannot assure you that the net proceeds will be used in a manner that would improve our results of operations or increase the ADS price, nor that these net proceeds will be placed only in investments that generate income or appreciate in value.

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

        Sales of our ADSs in the public market after this offering, or the perception that these sales could occur, could cause the market price of our ADSs to decline. All ADSs sold in this offering will be freely transferable without restriction or additional registration under the Securities Act. The remaining Class A ordinary shares issued and outstanding after this offering will be available for sale, upon the expiration of the 180-day lock-up period beginning from the date of this prospectus, subject to volume and other restrictions as applicable provided in Rules 144 and 701 under the Securities Act. Any or all of these shares may be released prior to the expiration of the lock-up period at the discretion of Citigroup Global Markets Inc. To the extent shares are released before the expiration of the lock-up period and sold into the market, the market price of our ADSs could decline.

        After completion of this offering, certain shareholders may cause us to register under the Securities Act the sale of their shares, subject to the 180-day lock-up period in connection with this offering. Registration of these shares under the Securities Act would result in ADSs representing these shares becoming freely tradable without restriction under the Securities Act immediately upon the effectiveness of such registration. Sales of these registered shares in the form of ADSs in the public market could cause the price of our ADSs to decline.

Our post-offering memorandum and articles of association contain anti-takeover provisions that could have a material adverse effect on the rights of holders of our Class A ordinary shares and the ADSs.

        We have adopted an amended and restated memorandum and articles of association that will become effective immediately prior to the completion of this offering. Our post-offering memorandum and articles of association contain provisions to limit the ability of others to acquire control of our company or cause us to engage in change-of-control transactions. These provisions could have the effect of depriving our shareholders of an opportunity to sell their shares at a premium over prevailing market prices by discouraging third parties from seeking to obtain control of our company in a tender offer or similar transaction. Our board of directors has the authority, without further action by our shareholders, to issue preferred shares in one or more series and to fix their designations, powers, preferences, privileges and relative participating, optional or special rights and the qualifications, limitations or restrictions, including dividend rights, conversion rights, voting rights, terms of redemption and liquidation preferences, any or all of which may be greater than the rights associated with our ordinary shares, including Class A ordinary shares represented by ADSs. 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

62

Table of Contents

shares, the price of the ADSs may fall and the voting and other rights of the holders of our Class A ordinary shares and the ADSs may be materially and adversely affected.

Our post-offering memorandum and articles of association and the deposit agreement provide that the United States District Court for the Southern District of New York (or, if the United States District Court for the Southern District of New York lacks subject matter jurisdiction over a particular dispute, the state courts in New York County, New York) is the exclusive judicial forum within the U.S. for the resolution of any complaint asserting a cause of action arising out of or relating in any way to the federal securities laws of the United States, and any suit, action or proceeding arising out of or relating in any way to the ADSs or the deposit agreement, which could limit the ability of holders of our Class A ordinary shares, the ADSs or other securities to obtain a favorable judicial forum for disputes with us, our directors and officers, the depositary, and potentially others.

        Our post-offering memorandum and articles of association provide that the United States District Court for the Southern District of New York (or, if the United States District Court for the Southern District of New York lacks subject matter jurisdiction over a particular dispute, the state courts in New York County, New York) is the exclusive forum within the United States for the resolution of any complaint asserting a cause of action arising out of or relating in any way to the federal securities laws of the United States, regardless of whether such legal suit, action, or proceeding also involves parties other than our company. The deposit agreement provides that the United States District Court for the Southern District of New York (or, if the United States District Court for the Southern District of New York lacks subject matter jurisdiction over a particular dispute, the state courts in New York County, New York) shall have exclusive jurisdiction over any suit, action or proceeding against or involving us or the depositary, arising out of or relating in any way to the deposit agreement or the transactions contemplated thereby or by virtue of owning the ADSs. The enforceability of similar federal court choice of forum provisions in other companies' organizational documents has been challenged in legal proceedings in the United States, and it is possible that a court could find this type of provision to be inapplicable or unenforceable. If a court were to find the federal choice of forum provision contained in our post-offering memorandum and articles of association or the deposit agreement to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions. If upheld, the forum selection clause in our post-offering memorandum and articles of association, as well as the forum selection provision in the deposit agreement, may limit a security-holder's ability to bring a claim against us, our directors and officers, the depositary, and potentially others in his or her preferred judicial forum, and this limitation may discourage such lawsuits. Holders of our shares or the ADSs will not be deemed to have waived our compliance with the federal securities laws and the regulations promulgated thereunder pursuant to the exclusive forum provision in the post-offering memorandum and articles of association and deposit agreement.

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

        Your ADSs are transferable on the books of the depositary. However, the depositary may close its books at any time or from time to time when it deems expedient in connection with the performance of its duties. The depositary may close its books from time to time for a number of reasons, including in connection with corporate action events, in emergencies, and on weekends and public holidays. The depositary may refuse to deliver, transfer or register transfers of the ADSs generally when our share register or the books of the depositary are closed, or at any time if we or the depositary thinks it is advisable to do so because of any requirement of law or of any government or governmental body, or under any provision of the deposit agreement, or for any other reason.

63

Table of Contents

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

You may 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 amended and restated memorandum and articles of association, the Companies Act (2021 Revision) of the Cayman Islands and the common law of the Cayman Islands. The rights of shareholders to take action against our directors, actions by our minority shareholders and the fiduciary duties of our directors to us under Cayman Islands law are to a large extent governed by the common law of the Cayman Islands. The common law of the Cayman Islands is derived in part from comparatively limited judicial precedent in the Cayman Islands as well as from the common law of England, the decisions of whose courts are of persuasive authority, but are not binding, on a court in the Cayman Islands. The rights of our shareholders and the fiduciary duties of our directors under Cayman Islands law are not as clearly established as they would be under statutes or judicial precedents in some jurisdictions in the United States. In particular, the Cayman Islands has a less developed body of securities laws than the United States. Some U.S. states, such as Delaware, have more fully developed and judicially interpreted bodies of corporate law than the Cayman Islands. In addition, Cayman Islands companies may not have the standing to initiate a shareholder derivative action in a federal court of the United States.

        Shareholders of Cayman Islands exempted companies like us have no general rights under Cayman Islands law to inspect corporate records or to obtain copies of lists of shareholders of these companies. Our directors have discretion under our post-offering 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 management, members of our 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 Act of the Cayman Islands and the laws applicable to companies incorporated in the United States and their shareholders, see "Description of Share Capital—Our Post-Offering Memorandum and Articles of Association—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 current operations are conducted in China. In addition, most of

64

Table of Contents

our current directors and officers are nationals and residents of countries other than 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."

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

        As a holder of our ADSs, you will only be able to exercise the voting rights with respect to the underlying Class A ordinary shares in accordance with the provisions of the deposit agreement. Under the deposit agreement, you must vote by giving voting instructions to the depositary. Upon receipt of your voting instructions, the depositary will vote the underlying Class A ordinary shares in accordance with these instructions. You will not be able to directly exercise your right to vote with respect to the underlying shares unless you withdraw the Class A ordinary shares. When a general meeting is convened, you may not receive sufficient advance notice to withdraw the shares underlying your ADSs to allow you to vote with respect to any specific matter. If we ask for your instructions, the depositary will notify you of the upcoming vote and will arrange to deliver our voting materials to you. We cannot assure you that you will receive the voting materials in time to ensure that you can instruct 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 vote and you may have no legal remedy if the shares underlying your ADSs are not voted as you requested. Furthermore, as a Cayman Islands exempted company, we are not obliged by the Companies Law (Revised) of the Cayman Islands to call shareholders' annual general meetings.

The depositary for our ADSs will give us a discretionary proxy to vote our Class A ordinary shares underlying your ADSs if you do not timely provide voting instructions to the depositary in accordance with the deposit agreement, except in limited circumstances, which could adversely affect your interests.

        Under the deposit agreement for the ADSs, if you do not timely provide voting instructions to the depositary, the depositary will give us a discretionary proxy to vote our Class A ordinary shares underlying your ADSs at shareholders' meetings unless:

•

we have failed to timely provide the depositary with notice of the meeting and related voting materials;



•

we have instructed the depositary that we do not wish a discretionary proxy to be given;



•

we have informed the depositary that there is substantial opposition as to a matter to be voted on at the meeting;



•

we have informed the depositary that a matter to be voted on at the meeting may have an adverse impact on shareholders; or



•

the voting at the meeting is to be made on a show of hands.

        The effect of this discretionary proxy is that if you do not timely provide voting instructions to the depositary in the manner required by the deposit agreement, you cannot prevent our Class A ordinary shares underlying your ADSs from being voted, except under the circumstances described above. This may make it more difficult for shareholders to influence the management of our company. Holders of our Class A ordinary shares are not subject to this discretionary proxy.

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 the United States District Court for the Southern District of New York (or, if the United States District Court for the Southern District of New York lacks subject matter jurisdiction over a particular dispute, in the state courts in New York County, New York) shall have exclusive jurisdiction to hear and determine claims arising out of or relating in any way to the deposit agreement (including claims arising under the Exchange Act or the Securities Act) and in that regard, to the fullest extent permitted by law, ADS holders waive the right to a jury trial of any claim they may have against us or the depositary arising out of or relating to our shares, the ADSs or the deposit agreement, including any claim under the U.S. federal securities laws, to the fullest extent permitted by law.

        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. In determining whether to enforce a contractual pre-dispute jury trial waiver provision, courts will generally consider whether a party knowingly, intelligently and voluntarily waives 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 or the depositary, lead to increased costs to bring a claim, limited access to information and other imbalances of resources between such holder and us, or limit such holder's ability to bring a claim in a judicial forum that such holder finds favorable. If a lawsuit is brought against us or the depositary under the deposit agreement, it may be heard only by a judge or justice of the applicable trial court, which would be conducted according to different civil procedures and may result in different outcomes than a trial by jury would have had, including results that could be less favorable to the plaintiff(s) in any such action.

        Nevertheless, if this jury trial waiver provision is not enforced, to the extent a court action proceeds, it would proceed under the terms of the deposit agreement with a jury trial. No condition, stipulation or provision of the deposit agreement or ADSs shall relieve us or the depositary from our respective obligations to comply with the Securities Act and the Exchange Act nor serve as a waiver by any holder or beneficial owner of ADSs of compliance with the U.S. federal securities laws and the rules and regulations promulgated thereunder.

As a company incorporated in the Cayman Islands, we are permitted to adopt certain home country practices in relation to corporate governance matters that differ significantly from the NYSE listing standards.

        As a Cayman Islands company listed on the NYSE, we are subject to the NYSE listing standards, which requires listed companies to have, among other things, a majority of their board members to be independent and independent director oversight of executive compensation and nomination of directors. However, NYSE rules permit a foreign private issuer like us to follow the corporate governance practices of its home country. Certain corporate governance practices in the Cayman Islands, which is our home country, may differ significantly from the NYSE listing standards.

66

Table of Contents

        We are permitted to elect to rely on home country practice to be exempted from the corporate governance requirements. If we choose to follow home country practice in the future, our shareholders may be afforded less protection than they would otherwise enjoy if we complied fully with the NYSE listing standards.

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 NYSE. 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 classified as a passive foreign investment company, or PFIC, for U.S. federal income tax purposes for any taxable year, which could result in adverse U.S. federal income tax consequences to U.S. Holders of our ADSs or Class A ordinary shares.

        A non-U.S. corporation, such as our company, will be classified as a passive foreign investment company, or PFIC, for any taxable year if either (1) at least 75% of its gross income for such year consists of certain types of "passive" income, or the income test; or (2) at least 50% of the value of its assets (generally determined on the basis of a quarterly average) during such year is attributable to assets that produce passive income or are held for the production of passive income, or the asset test. Although the law in this regard is not entirely clear, we treat our consolidated VIE and its subsidiaries as being owned by us for U.S. federal income tax purposes because we control their management decisions and are entitled to substantially all of the economic benefits associated with them. As a result, we consolidate their results of operations in our consolidated financial statements. If it were determined, however, that we are not the owner of our consolidated VIE and its subsidiaries for U.S. federal income tax purposes, we may be treated as a PFIC for the current taxable year and any subsequent taxable year. Assuming that we are the owner of our consolidated VIE and its subsidiaries for U.S. federal income tax purposes, and based on the current and anticipated value of our assets and composition of our income and assets (taking into account the expected cash proceeds from, and our anticipated market capitalization following, this offering), we do not presently expect to be a PFIC for the current taxable year or the foreseeable future.

67

Table of Contents

        While we do not expect to be or become a PFIC, no assurance can be given in this regard because the determination of whether we are or will become a PFIC for any taxable year is a fact-intensive inquiry made annually that depends, in part, upon the composition of our income and assets. Fluctuations in the market price of our ADSs may cause us to be or become a PFIC for the current or subsequent taxable years because the value of our assets for the purpose of the asset test, including the value of our goodwill and other unbooked intangibles, may be determined by reference to the market price of our ADSs from time to time (which may be volatile). The composition of our income and assets may also be affected by how, and how quickly, we use our liquid assets and the cash raised in this offering.

        If we were to be or become a PFIC for any taxable year during which a U.S. Holder (as defined in "Taxation—United States Federal Income Tax Considerations") holds our ADSs or Class A ordinary shares, certain adverse U.S. federal income tax consequences could apply to such U.S. Holder. See "Taxation—United States Federal Income Tax Considerations—Passive Foreign Investment Company Rules."

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

        We have 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 NYSE, impose various requirements on the corporate governance practices of public companies. We expect these rules and regulations to increase our legal and financial compliance costs and to make some corporate activities more time-consuming and costly.

        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.

        In addition, after we are no longer an "emerging growth company," we expect to incur significant expenses and devote substantial management effort toward ensuring compliance with the requirements of Section 404 of the Sarbanes-Oxley Act of 2002 and the other rules and regulations of the SEC.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

        This prospectus contains forward-looking statements that reflect our current expectations and views of future events. The forward-looking statements are contained principally in the sections entitled "Prospectus Summary," "Risk Factors," "Management's Discussion and Analysis of Financial Condition and Results of Operations" and "Business." Known and unknown risks, uncertainties and other factors, including those listed under "Risk Factors," may cause our actual results, performance or achievements to be materially different from those expressed or implied by the forward-looking statements.

        You can identify some of these forward-looking statements by words or phrases such as "may," "will," "expect," "anticipate," "aim," "estimate," "intend," "plan," "believe," "is/are likely to," "potential," "continue" or other similar expressions. We have based these forward-looking statements largely on our current expectations and projections about future events that we believe may affect our financial condition, results of operations, business strategy and financial needs. These forward-looking statements include statements relating to:

•

our mission, goals and strategies;



•

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



•

the expected growth of China's e-vapor industry;



•

our expectations regarding demand for and market acceptance of our e-vapor products;



•

our expectations regarding our relationships with users, distributors, retailers, suppliers, manufacturers and other partners;



•

competition in our industry;



•

our proposed use of proceeds; and



•

relevant government policies and regulations relating to our industry.

        These forward-looking statements involve various risks and uncertainties. Although we believe that our expectations expressed in these forward-looking statements are reasonable, our expectations may later be found to be incorrect. Our actual results could be materially different from our expectations. Important risks and factors that could cause our actual results to be materially different from our expectations are generally set forth in "Prospectus Summary—Our Challenges," "Risk Factors," "Management's Discussion and Analysis of Financial Condition and Results of Operations," "Business," "Regulation" and other sections in this prospectus. You should read thoroughly this prospectus and the documents that we refer to with the understanding that our actual future results may be materially different from and worse than what we expect. We qualify all of our forward-looking statements by these cautionary statements.

        This prospectus contains certain data and information that we obtained from various government and private publications. Statistical data in these publications also include projections based on a number of assumptions. The e-vapor industry may not grow at the rate projected by market data, or at all. Failure of this market to grow at the projected rate may have a material and adverse effect on our business and the market price of the ADSs. In addition, the rapidly evolving nature of this industry results in significant uncertainties for any projections or estimates relating to the growth prospects or future condition of our market. Furthermore, if any one or more of the assumptions underlying the market data are later found to be incorrect, actual results may differ from the projections based on these assumptions. You should not place undue reliance on these forward-looking statements.

        The forward-looking statements made in this prospectus relate only to events or information as of the date on which the statements are made in this prospectus. Except as required by law, we undertake no obligation to update or revise publicly any forward-looking statements, whether as a result of new

information, future events or otherwise, after the date on which the statements are made or to reflect the occurrence of unanticipated events. You should read this prospectus and the documents that we refer to in this prospectus and have filed as exhibits to the registration statement, of which this prospectus is a part, completely and with the understanding that our actual future results may be materially different from what we expect.

USE OF PROCEEDS

        We estimate that we will receive net proceeds from this offering of approximately US$1,347.5 million, or approximately US$1,550.3 million if the underwriters exercise their over-allotment option in full, after deducting underwriting discounts and commissions and the estimated offering expenses payable by us.

        The primary purposes of this offering are to create a public market for our shares for the benefit of all shareholders, retain talented employees by providing them with equity incentives and obtain additional capital. We plan to use the net proceeds of this offering as follows:

•

approximately 30% for development of products and technologies and scientific research;



•

approximately 25% for enhancement of distribution and retail network;



•

approximately 25% for improvement of supply chain capabilities; and



•

the balance for general corporate purposes and working capital.

        The foregoing represents our current intentions based upon our present plans and business conditions to use and allocate the net proceeds of this offering. Our management, however, will have significant flexibility and discretion to apply the net proceeds of this offering. If an unforeseen event occurs or business conditions change, we may use the proceeds of this offering differently than as described in this prospectus. See "Risk Factors—General Risks Relating to Our ADSs and This Offering—We have not determined a specific use for a portion of the net proceeds from this offering and we may use these proceeds in ways with which you may not agree."

        Pending any use described above, we plan to invest the net proceeds in short-term, interest-bearing, debt instruments or demand deposits.

        In using the proceeds of this offering, we are permitted under PRC laws and regulations as an offshore holding company to provide funding to our PRC subsidiaries only through loans or capital contributions and to our VIE only through loans, subject to satisfaction of applicable government registration and approval requirements. We cannot assure you that we will be able to obtain these government registrations or approvals on a timely basis, or 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 may delay us from using the proceeds of this offering to make loans or additional capital contributions to our PRC subsidiaries and to make loans to our VIE, which could materially and adversely affect our liquidity and our ability to fund and expand our business."

DIVIDEND POLICY

        Our board of directors has discretion on 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. In either case, all dividends are subject to certain restrictions under Cayman Islands law, namely that our company may only pay dividends out of profits or share premium, and provided always that in no circumstances may a dividend be paid if this would result in our company being unable to pay its debts as they fall due in the ordinary course of business. Even if we decide to pay dividends, the form, frequency and amount will depend upon our future operations and earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that the board of directors may deem relevant.

        We do not have any present plan to pay any cash dividends on our ordinary shares after this offering. We currently intend to retain most, if not all, of our available funds and any future earnings to operate and expand our business.

        We are a holding company incorporated in the Cayman Islands. We may rely on dividends from our subsidiaries 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 on Foreign Exchange and Dividend Distribution."

        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." Cash dividends on our ordinary shares, if any, will be paid in U.S. dollars.

CAPITALIZATION

        RLX Technology Inc. is currently 100% owned by Relx Inc. We expect that, within six months following this offering, the existing shareholders of Relx Inc. would become our shareholders through a distribution of our shares in proportion to Relx Inc.'s shareholding structure at the time, and Relx Inc. will remain our parent company until this shareholding change takes place.

        The following table sets forth our capitalization as of September 30, 2020:

•

on an actual basis;



•

on a pro forma basis to reflect (i) the deemed settlement of amount due to Relx Inc. of RMB600 million as the contribution to us on November 25, 2020, (ii) the re-designation of 1,436,815,570 ordinary shares held by Relx Inc. into Class B ordinary shares on a one-for-one basis and the increase of authorized share capital immediately prior to the completion of this offering, and (iii) recognition of share-based compensation expenses to be allocated by Relx Inc. to us related to immediate vesting of certain restricted ordinary shares issued by Relx Inc., upon the completion of this offering; and



•

on a pro forma as adjusted basis to reflect (i) the deemed settlement of amount due to Relx Inc. of RMB600 million as the contribution to us on November 25, 2020, (ii) the re-designation of 1,436,815,570 ordinary shares held by Relx Inc. into Class B ordinary shares on a one-for-one basis and the increase of authorized share capital immediately prior to the completion of this offering, (iii) recognition of share-based compensation expenses to be allocated by Relx Inc. to us related to immediate vesting of certain restricted ordinary shares issued Relx Inc., upon the completion of this offering, (iv) the issuance and sale of 116,500,000 Class A ordinary shares in the form of ADSs by us in this offering at an initial public offering price of US$12.00 per ADS, after deducting the underwriting discounts and commissions and estimated offering expenses payable by us, assuming the underwriters do not exercise their over-allotment option, and (v) the completion of the abovementioned shareholding change.

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 ordinary share is substantially in excess of the book value per ordinary share attributable to the existing shareholder for our presently outstanding ordinary shares.

        On a pro forma basis that reflects (i) the deemed settlement of amount due to Relx Inc. of RMB600 million as the contribution to us on November 25, 2020, (ii) the re-designation of 1,436,815,570 ordinary shares held by Relx Inc. into Class B ordinary shares on a one-for-one basis and the increase of authorized share capital immediately prior to the completion of this offering, and (iii) recognition of share-based compensation expenses to be allocated by Relx Inc. to us related to immediate vesting of certain restricted ordinary shares issued by Relx Inc., upon the completion of this offering, our net tangible book value as of September 30, 2020 was US$154.7 million, representing US$0.11 per ordinary share as of that date and US$0.11 per ADS. Net tangible book value represents the amount of our total consolidated tangible assets, less the amount of our total consolidated liabilities. Dilution is determined by subtracting pro forma net tangible book value per ordinary share, after giving effect to the additional proceeds we will receive from this offering, from the initial public offering price of US$12.00 per ordinary share, and after deducting underwriting discounts and commissions and estimated offering expenses payable by us. Because the Class A ordinary shares and Class B ordinary shares have the same dividend and other rights, except for voting and conversion rights, the dilution is presented based on all issued and outstanding ordinary shares, including Class A ordinary shares and Class B ordinary shares.

        Without taking into account any other changes in the net tangible book value after September 30, 2020, other than to give effect to (i) the deemed settlement of amount due to Relx Inc. of RMB600 million as the contribution to us on November 25, 2020, (ii) the re-designation of 1,436,815,570 ordinary shares held by Relx Inc. into Class B ordinary shares on a one-for-one basis and the increase of authorized share capital immediately prior to the completion of this offering, (iii) recognition of share-based compensation expenses to be allocated by Relx Inc. to us related to immediate vesting of certain restricted ordinary shares issued by Relx Inc., upon the completion of this offering, and (iv) our sale of the ADSs offered in this offering at the initial public offering price of US$12.00 per ADS, 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 September 30, 2020 would have been US$1.5 billion, or US$0.97 per ordinary share and US$0.97 per ADS. This represents an immediate increase in net tangible book value of US$0.92 per ordinary share and US$0.92 per ADS to the existing shareholder and an immediate dilution in net tangible book value of

75

US$11.03 per ordinary share and US$11.03 per ADS to investors purchasing ADSs in this offering. The following table illustrates such dilution:

        The following table summarizes, on a pro forma as adjusted basis as of September 30, 2020, the differences between existing shareholder and the new investors with respect to the number of ordinary shares (in the form of ADSs or shares) purchased from us, the total consideration paid and the average price per ordinary share and per ADS paid before deducting the underwriting discounts and commissions and estimated offering expenses payable by us. The total number of ordinary shares does not include Class A ordinary shares underlying the ADSs issuable upon the exercise of the over-allotment option granted to the underwriters.
