RISK FACTORS

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

Risks Related to Our Business

If we fail to increase student enrollments, our net revenues may decline, and we may not be able to maintain growth.

We generate revenue primarily from the tuition we collect from our students. It is critical for us to enroll prospective students in a cost-effective manner. Some of the factors, many of which are largely beyond our control, could prevent us from successfully increasing enrollments of new students in a cost-effective manner, or at all. These factors include, among other things, (i) reduced interest in the degrees, diplomas, professions or certifications for which our course offerings are designed; (ii) negative publicity or perceptions regarding us, or online education services in general; (iii) the emergence of alternative course delivery models; (iv) the inability of students to pay the tuition; (v) increasing market competition, particularly price reductions by competitors that we are unable or unwilling to match; and (vi) adverse changes in relevant government policies or general economic conditions. If one or more of these factors reduce market demand for our services, our student enrollments could be negatively affected or our costs associated with student acquisition and retention could increase, or both, any of which could materially affect our ability to grow our gross billings and net revenues. These developments could also harm our brand and reputation, which would negatively impact our ability to expand our business.

We have grown rapidly and expect to continue to invest in our growth for the foreseeable future. If we fail to manage this growth effectively, the success of our business model will be compromised.

We have experienced rapid growth in gross billings and net revenues in recent years, primarily driven by our fast-growing student enrollments since our transition to an online course delivery model in 2014 which allows students to access our courses from anywhere connected to the internet. Our net revenues grew by 163.4% from RMB159.0 million in 2015 to RMB418.9 million in 2016 and further increased by 131.6% to RMB970.2 million (US$149.1 million) in 2017. Over the same periods, our gross billings grew by 66.1% to RMB741.0 million from RMB446.1 million and further increased by 221.4% to RMB2,381.8 million (US$366.1 million).

Our rapid growth has placed, and will continue to place, a significant strain on our sales and marketing capacities, administrative and operating infrastructure, facilities and other resources. To maintain our growth, we need to continue to acquire more students, scale up our course offerings, increase our academic and administrative faculty, as well as strengthen our platforms and systems. We will also be required to refine our operational, financial and management controls and reporting systems and procedures. If we fail to efficiently manage this expansion of our business, our costs and expenses may increase more than we plan and we may not successfully attract a sufficient number of students and qualified academic and administrative faculty in a cost-effective manner, respond to competitive challenges, or otherwise execute our business plans. In addition, we may, as part of carrying out our growth strategies, adopt new initiatives to offer additional course packages and educational content and to implement new pricing models and strategies. We cannot assure you that these initiatives may achieve the anticipated results. These proposed changes may not be well received by our existing and prospective students, in which case their experience with our education services may suffer, which could damage our reputation and business prospect.

18

Our ability to effectively implement our strategies and manage any significant growth of our business will depend on a number of factors, including our ability to: (i) identify and effectively market our products and services in new markets with sufficient growth potential; (ii) develop and improve course offerings and educational contents to make them appealing to existing and prospective students, particularly working adult students; (iii) maintain and increase our student enrollments; (iv) effectively recruit, train and motivate a large number of new employees, including our faculty members and sales and marketing personnel; (v) successfully implement enhancements and improvements to the systems and platforms; (vi) continue to improve our operational, financial and management controls and efficiencies; (vii) protect and further develop our intellectual property rights; and (viii) make sound business decisions in light of the scrutiny associated with operating as a public company. These activities require significant capital expenditures and investment of valuable management and financial resources, and our growth will continue to place significant demands on our management. There are no guarantees that we will be able to effectively manage any future growth in an efficient, cost-effective and timely manner, or at all. Our growth in a relatively short period of time is not necessarily indicative of results that we may achieve in the future. If we do not effectively manage the growth of our business and operations, our reputation, results of operations and overall business and prospects could be negatively impacted.

We have a history of net losses and we may not achieve profitability in the future.

We had net losses of RMB318.3 million, RMB253.6 million and RMB918.7 million (US$141.2 million) in 2015, 2016 and 2017, respectively. We cannot assure you that we will be able to generate net profits in the future.

We expect that our sales and marketing expenses will continue to increase as we invest in branding and sales and marketing efforts, including hiring additional sales and marketing personnel, investing in data analytics in the student counseling and sales process, and broadening our online marketing channels. In addition, we intend to continue to invest heavily for the foreseeable future in increasing our market share, improving the capacity of our technology infrastructure to better support an even larger student base and to offer additional courses and educational content.

These efforts may be more costly than we expect and our net revenues may not increase sufficiently to offset these expenses. We may continue to take actions and make investments that do not generate optimal short-term financial results and may even result in increased operating losses in the short term with no assurance that we will eventually achieve our intended long-term benefits or profitability. These factors, among others set out in this “Risk Factors” section, may negatively affect our ability to achieve profitability in the near term, if at all.

If we are unable to conduct sales and marketing activities cost-effectively, our results of operations and financial condition may be materially and adversely affected.

We rely heavily on our sales and marketing efforts to increase student enrollments. Our sales and marketing expenses primarily include employee salaries and student acquisition expenses. We incurred approximately RMB333.3 million, RMB503.6 million and RMB1,351.8 million (US$207.8 million), respectively, in sales and marketing expenses in 2015, 2016 and 2017. We expect our sales and marketing expenses to continue to increase in the future as we further expand our operations.

Our sales and marketing activities may not be well received by the market and may not result in the levels of sales that we anticipate. We also may not be able to retain or recruit a sufficient number of experienced sales and marketing personnel, or to train newly hired sales and marketing personnel, which we believe is critical to implementing our sales and marketing strategies cost-effectively. Further, sales and marketing approaches and tools in China’s online education market are evolving rapidly. This requires us to continually enhance our sales and marketing approaches and experiment with new methods to keep pace with industry developments and student preferences. Moreover, our sales and marketing activities may be deemed to violate PRC laws and regulations, and we may be exposed to administrative penalties, such as paying fines or publishing explanatory

19

notes to limit the adverse effects of our marketing efforts. If we are deemed guilty of significant infringements, we may be ordered to cease sales and marketing activities temporarily and our business license may be revoked. Failure to engage in sales and marketing activities in a compliant and cost-effective manner may reduce our market share, cause our revenues and gross billings to decline, negatively impact our profitability, and materially harm our business, financial condition and results of operation.

We may be adversely affected by any negative publicity concerning us and our business, shareholders, affiliates, directors, officers and employees and the industry in which we operate, regardless of its accuracy, that could harm our reputation and business.

Negative publicity about us and our business, shareholders, affiliates, directors, officers, and teachers and other employees, as well as the industry in which we operate, can harm our operations. We have been exposed to negative publicity concerning refund dispute and administrative penalty and alledged improper or misleading statement made in our sales and marketing activities in the past. Negative publicity concerning these parties could be related to a wide variety of matters, including, but are not limited to:

In addition to traditional media, there has been an increasing use of social media platforms and similar devices in China, including instant messaging applications, such as Weixin/WeChat, social media websites and other forms of internet-based communications that provide individuals with access to a broad audience of consumers and other interested persons. The availability of information on instant messaging applications and social media platforms is virtually immediate as is its impact without affording us an opportunity for redress or correction. The opportunity for dissemination of information, including inaccurate information, is seemingly limitless and readily available. Information concerning our company, shareholders, directors, officers and employees may be posted on such platforms at any time. The risks associated with any such negative publicity or incorrect information cannot be completely eliminated or mitigated and may materially harm our reputation, business, financial condition and results of operations.

We face risks associated with our lack of a private school operating permit for our online education services as well as uncertainties surrounding PRC laws and regulations governing the education industry in general, including the Law for Promoting Private Education and its Implementation Rules.

Beijing Sunlands, through which we operate our online education business, currently does not hold a private school operating permit for our online education services, and we may be subject to risks of administrative sanctions due to our lack of such permit.

Pursuant to the Administrative Regulations on Educational Websites and Online and Distance Education Schools promulgated by the Ministry of Education of the PRC, or the MOE, on July 5, 2000, “educational

20

websites and online education schools” that provide educational services in relation to higher education, elementary education, pre-school education, teaching education, occupational education, adult and other education and public educational information services, are subject to approval from competent education authorities, depending on the type of education service provided. In February 2016, the State Council issued a government decision which explicitly withdrew the above-mentioned approval requirement. See “Regulation—Regulations on Online and Distance Education.” On November 7, 2016, China’s National People’s Congress passed an amendment to the Promotion of Private Education Law, or the Amendment, which became effective on September 1, 2017. The Amendment applies different regulatory requirements to non-profit and for-profit private schools. See “Regulation—Regulation Relating to Private Education—The Law for Promoting Private Education and its Implementing Rules.”

In December 2016, several PRC government agencies, including the MOE, the State Administration for Industry and Commerce, or the SAIC, and the Ministry of Human Resources and Social Welfare, jointly promulgated the Implementation Rules on the Supervision and Administration of For-profit Private Schools, or the Implementation Rules. Under the Implementation Rules, the establishment, division, merger or any other material change in a for-profit private school shall be approved by the competent education authorities or the authorities in charge of labor and social welfare and be registered with the competent local branch of SAIC, and a duly approved private school will be granted a private school operating permit. The Implementation Rules also provide that the provisions contained therein should be applicable to “for-profit private training institutions” in an analogous manner. See “Regulations—Regulation Relating to Private Education—The Law for Promoting Private Education and its Implementing Rules. ”

As of the date of this prospectus, we have not received any notice of warning or been subject to any penalties or disciplinary action from government authorities due to our lack of a private school operating permit for our online education services. In addition, we have made inquiries to the relevant education authorities and were informed that online education service providers were not required to obtain a private school operating permit for the provision of online education services, and that if such educational authorities were to require us to obtain a private school operating permit in the future, such authorities would not subject us to penalties for the provision of our services without obtaining a private school operating permit. Nonetheless, as advised by Tian Yuan Law Firm, our PRC legal counsel, the current PRC laws and regulations, including the Amendment and the Implementation Rules, remain unclear as to whether the requirement for a private school operating permit is applicable to an online education service provider. We cannot assure you that the PRC government will not in the future require us to obtain a private school operating permit, given the lack of clear and consistent statutory interpretation regarding the implementation of the Amendment and the Implementation Rules and other relevant laws and regulations. If the PRC government requires us to obtain a private school operating permit or introduces additional amendments and guidelines to expand the coverage of the Amendment to explicitly cover online education service providers, and if we fail to do so, we may be subject to fines up to five times the illegitimate gains generated from the provision of training services without a proper license, other administrative sanctions, such as being ordered to refund tuition payments to the students, or criminal liabilities, for our lack of a private school operating permit. We may also be subject to regulatory requirements that are more stringent than the ones currently applicable to us, including those relating to sales and marketing, courses and educational content offerings, teachers’ qualification, as well as tuition fee rates and tuition refund policies, or laws and regulations that require us to obtain and maintain additional licenses and permits, and we may incur substantial expenses or alter or change our business to comply with these requirements.

Under the Amendment and the Implementation Rules, a material change in a for-profit private school shall be approved by the competent education authorities or the authorities in charge of labor and social welfare before it can be registered with the competent local branch of SAIC. If we were required to expand the authorized scope of our business license to cover our business of online education services, which shall be registered with the SAIC, to comply with applicable licensing requirements, we may not able to do so before we have obtained a private school operating permit. If any of the foregoing were to happen, our business operations may be

21

disrupted, and our financial condition, results of operations and reputation may be materially and adversely affected.

We face regulatory risks and uncertainties associated with our teachers’ lack of teaching licenses.

Pursuant to the Implementation Rules, the teachers employed by a for-profit private school shall obtain the teaching licenses or relevant professional skill qualifications required by PRC laws and regulations, although the definition or the scope of the “relevant professional skill qualifications” is not explicitly stated in the Implementation Rules. A substantial majority of our teachers currently do not hold teaching licenses.

As of the date of this prospectus, we have not received any notice of warning or been subject to any penalties or disciplinary action from government authorities due to the lack of teaching licenses. As advised by Tian Yuan Law Firm, our PRC legal counsel, the current PRC laws and regulations, including the Amendment and the Implementation Rules, remain unclear as to whether the Implementation Rules is applicable to an online education service provider like us, and accordingly, whether our teachers are required to obtain and hold teaching licenses. We cannot assure you that the PRC government authorities will not take a contrary view. In the event that in the future our teachers are required by laws to obtain teaching licenses, we cannot assure you that they can meet the requirements for applying for teaching licenses. If our teachers are not able to apply for and obtain the teaching licenses on a timely basis, or at all, we may be ordered to rectify such noncompliance or subject to penalties under the then-effective PRC laws and regulations, in which case our business may be disrupted, and our financial condition, reputation and prospects would be materially and adversely affected.

We face regulatory risks and uncertainties with respect to the licensing requirement for the online transmission of internet audio-visual programs.

On December 20, 2007, the State Administration of Press Publication Radio Film and Television, or SAPPRFT, and the Ministry of Industry and Information Technology, or the MIIT, jointly promulgated the Administrative Provisions on Internet Audio Visual Program Services, or the Audio Visual Program Provisions, which became effective on January 31, 2008 and were amended on August 28, 2015. Among other things, the Audio Visual Program Provisions stipulate that no entities or individuals may provide Internet audio-visual program services without a License for Online Transmission of Audio-Visual Programs issued by SAPPRFT or completing the relevant filing with SAPPRFT or its local bureaus, and only state-owned or state-controlled entities are eligible to apply for a License for Online Transmission of Audio Visual Programs. On April 1, 2010, SAPPRFT promulgated the Provisional Implementations of Tentative Categories of Internet Audio Visual Program Services, or the Categories, which clarified the scope of Internet audio-visual programs services, which was amended on March 10, 2017. According to the Categories, there are four categories of Internet audio-visual program services which are further divided into seventeen sub-categories. Sub-category No. 3 to the second category covers the making and editing of certain specialized audio-visual programs concerning, among other things, educational content, and broadcasting such content to the general public online. Sub-category No. 5 of the first category and sub-category No. 7 of the second category cover the live broadcasting of important political, martial, economic, social, cultural, sports activities or events or general social or community cultural activities, sports games and other organized activities. However, there are still significant uncertainties relating to the interpretation and implementation of the Audio Visual Program Provisions, in particular, the scope of “internet audio-visual programs.” See “Regulations—Regulations Relating to Online Transmission of Audio-Visual Programs.”

We deliver our courses in live streaming format. Our teachers and students communicate and interact live with each other via our virtual learning community. The audio and video data are transmitted through the platforms between specific recipients instantly without any further redaction. We believe the nature of the raw data we transmit distinguishes us from general providers of internet audio-visual program services, such as the operator of online video websites, and the provision of the Audio-Visual Program Provisions are not applicable with regard to our offering of the courses. However, we cannot assure you that the competent PRC government

22

authorities will not ultimately take a view contrary to our opinion. In addition, we also offer video recordings of live streaming courses and certain other audio-video contents on our online platforms to our students as supplementary course materials on our platforms. If the government authorities determine that our offering of the courses fall within the relevant category of Internet audio-visual program services under the Categories, we may be required to obtain the License for Online Transmission of Audio Visual Programs.

The Categories describe “Internet audio-visual program services” in a very broad, vague manner and are unclear as to whether online courses, whether delivered in a live streaming format or through video recordings, fall into the definition of audio-visual programs. We have made inquiries to the relevant bureaus of SAPPRFT and were informed that online educational content provided through live streaming or recorded courses does not fall within the scope of internet audio-visual programs, the transmission of which does not require a License for Online Transmission of Audio-Visual Programs. We cannot assure you that the PRC government will not ultimately take a view that live streaming or recorded courses or any other content offered on our platforms are subject to the Audio Visual Program Provisions. We currently do not hold a License for Online Transmission of Audio Visual Programs, and since we are not a state-owned or state-controlled entity, we are not eligible to apply for such license. If the PRC government determines that our content should be considered as “internet audio-visual programs” for the purpose of the Audio-Visual Program Provisions, we may be required to obtain a License for Online Transmission of Audio Visual Programs. We are, however, not eligible apply for such license since we are not a state-owned or state-controlled entity. If this were to occur, we may be subject to penalties, fines, legal sanctions or an order to suspend the provision of our live streaming courses. As of the date of this prospectus, we have not received any notice of warning or been subject to penalties or other disciplinary action from the relevant governmental authorities regarding the lack of a License for Online Transmission of Audio Visual Programs in conducting of our business.

Our failure to obtain and maintain other approvals, licenses or permits applicable to our business could have a material adverse impact on our business, financial conditions and results of operations.

A number of PRC regulatory authorities, such as the SAIC, the Cyberspace Administration of China, the MITT, the SAPPRFT, and the State Council Information Office, the Ministry of Civil Affairs, and the Ministry of Human Resources and Social Welfare, oversee different aspects of our business operations, and we are required to obtain a wide range of government approvals, licenses and permits in connection with our operations.

We currently do not hold several approvals, licenses and permits that are required for certain aspects of our business operations. Under the current PRC laws and regulations, the provision of our educational content through our online platform may be considered “online publishing” and may require us to obtain an Internet Publishing License, which we currently do not have. See “Regulations—Regulations Relating to Online Publishing.” As of the date of this prospectus, we have submitted an application to the competent government authorities for the approval of an Internet Publishing License. However, we may not be able to receive the approval for such licenses in a timely manner, or at all. In addition, we do not have the Job Agency Service License required for the job referral services we provide to some of our students as an ancillary part of their course packages.

Furthermore, Beijing Sunlands, our consolidated VIE, and certain of its operating subsidiaries currently do not include “occupational training” and “educational facilitation services” in their authorized scope of business. Before the Amendment was issued, we attempted to apply to the competent authorities in Beijing to add “occupational training” and “educational facilitation services” to the authorized scope of business of Beijing Sunlands, but our application was rejected by such authorities without being provided any formal explanations for such rejection. After the issuance of the Amendment, based on our consultation with the competent government authorities, such government authorities currently may not accept applications for inclusion of “occupational training,” “educational facilitation services” or similar items in the scope of business of companies that do not hold a private school operating permit. For additional information about the private school operating permit, see “—We face risks associated with our lack of a private school operating permit for our online

23

education services as well as uncertainties surrounding PRC laws and regulations governing the education industry in general, including the Law for Promoting Private Education and its Implementation Rules.” Even if our application were to be accepted, there is no assurance that it will be approved by the government authorities in a timely fashion, or at all. If it comes to the attention of the government authorities that Beijing Sunlands is operating beyond its authorized scope of business, we may be subject to fines, confiscation of the gains derived from the noncompliant operations, or may be required to cease Beijing Sunlands’ noncompliant operations.

As of the date of this prospectus, we have not been subject to any fines or other form of regulatory or administrative penalties or sanctions due to the lack of any the above-mentioned approvals, licenses or permits. However, we cannot guarantee that the government authorities will not impose any penalties or sanctions on us in the future, which may include warnings, fines, mandates to remedy any violations, confiscation of the gains derived from the services for which approvals, licenses or permits are required, and/or an order to cease to provide such services. In addition, we cannot guarantee that the government will not promulgate new laws and regulations that require additional licenses, permits and/or approvals for the operation of any of our existing or future business. If we are unable to obtain such licenses, permits, or approvals in a timely fashion, we could be subject to penalties and operational disruption and our financial condition and results of operations could be adversely affected.

We have a limited history of operating as an online education service provider.

We have been a part of China’s education industry since we commenced operations in August 2003. Although we started exploring online course delivery model in 2011, we remained an offline, classroom-based education service provider until we transitioned to an online education model in 2014. Our limited history of operating as an online education service provider may not serve as an adequate basis for evaluating our future prospect and operating results, including gross billings, net revenue, cash flows and profitability. We have encountered, and may continue to encounter in the future, risks, challenges and uncertainties associated with operating an internet-based business, such as building and managing reliable and secure IT systems and infrastructure, addressing regulatory compliance and uncertainty, and hiring and training IT support staff, all of which we have limited experience with. In addition, we may be faced with additional risks and challenges associated with responding to the increasing mobile penetration in China. If we do not manage these risks successfully, our operating and financial results may differ materially from our expectations and our business may suffer.

We may not be able to continue to recruit, train and retain a sufficient number of qualified faculty members.

Our faculty members are key to the quality of our educational services, as well as our brand and reputation. Our ability to continue to attract faculty members, including teachers and mentors, with necessary experience and qualifications is a key driver in the success of our business. We seek to recruit qualified faculty members who are dedicated to teaching and are able to communicate with our students in an interactive online setting.

Additionally, given the interactive nature of our live streaming lessons, we tend to hire teachers and mentors with strong education background and good communication skills enabling them to engage and interact with students. The market for recruitment of faculty members in China is competitive. In order to recruit qualified full-time teachers and mentors, we must provide candidates with competitive compensation packages and offer attractive career development opportunities. Although we have not experienced major difficulties in recruiting or training qualified teachers and mentors in the past, we cannot guarantee we will be able to continue to recruit, train and retain a sufficient number of qualified faculty members in the future as we continue to expand our course offerings and business scale, which may have a material adverse effect on our business, financial condition and results of operations.

24

We may not be able to timely improve or expand our course and educational content offerings in a cost-effective manner to make them appealing to existing and prospective students, or at all.

We regularly and constantly update our existing courses and educational content and develop new courses and educational content to meet student’s demand and the latest market trends. The revisions, improvements and expansions of our existing course and content offerings and the development of new course and content offerings may not be accepted by existing or prospective students. Even if we are able to develop acceptable new course and educational content offerings, we may not be able to introduce them as quickly as students require or as quickly as our competitors introduce competing offerings. The process of performing detailed market research and recruiting qualified faculty for new course and educational content offerings could be costly and time-consuming. Furthermore, offering new courses or content or upgrading existing ones may require us to make significant investments in educational content development, increase sales and marketing efforts and reallocate resources from other uses, all of which may not be successful. If we are unsuccessful in pursuing course and educational content development and upgrading opportunities due to the financial constraints, failure to attract qualified faculty, or other factors, our ability to attract and retain students could be impaired and our financial results could suffer.

We face risks associated with our online live streaming course delivery model.

The online live streaming industry in China remains relatively young and untested, and there are limited proven methods to project user demand or preference or available industry standards on which we can rely. In the PRC, few institutions with large student enrollments have in the past adopted a live streaming course delivery model, and some of our target students may be inclined to choose traditional face-to-face lessons offered by offline learning centers as they find more familiar and reliable. We cannot assure you that our live streaming course delivery format will continue to be attractive to our students in the future. If our live streaming course delivery model becomes less appealing to our students, our business and prospects may be affected. In addition, as we continue to increase our student enrollments, there is no assurance that our live streaming capacity will be able to support a growing number of students accessing our courses online without any service interruptions. Furthermore, we cannot assure that we will be able to address PRC regulatory and legislative developments relating to online streaming business.

We rely on third-party service providers to support our online live streaming course delivery.

Currently, we rely upon certain third-party vendors to provide live streaming services to support our online course delivery. Because the live streaming technologies and infrastructure are owned and managed by third parties, any problems with the reliability and performance of such technologies and infrastructure could result in unanticipated delays and unscheduled service interruption could further cause us to be unable to deliver our courses in a live streaming format, forcing us to resort to using prerecorded lectures. Our inability to deliver live streaming courses during service interruptions may damage the quality of our education service and student engagement and experience and negatively impact our reputation, financial condition and results of operations.

We do not maintain long-term arrangements with our live streaming service providers. The term of the service agreements we enter into with third-party live streaming service providers are generally one year. If we cannot renew such agreements upon their expirations or terminations on commercially reasonable terms, or at all, or if the live streaming service providers become unwilling or unable to provide us with live streaming services at any time for any reasons, our ability to deliver live streaming online courses will be severely impacted, and our students’ learning experience and our reputation will be harmed.

We are currently in the process of developing our own proprietary live streaming platforms and applications, which are expected to be completed in 2018. There is, however, no assurance that we will succeed. If the development of proprietary live streaming technologies does not achieve the anticipated results, we may have to continue to rely on third-party vendors to provide us with the technologies and infrastructure necessary for the delivery of our online live streaming courses, which may negatively impact our business and prospects.

25

Failure to adequately and promptly respond to changes in the exams our students must take to pursue their desired degrees, diplomas or certifications could cause our education services to be less attractive to our students.

There have been continuous changes in the curriculum requirements associated with, and the format of, the exams our existing and prospective students must take to pursue their desired degrees, diplomas or certifications, the manner in which the exams are administered, as well as topics frequently tested in the exams. These changes require us to continually update and enhance our course offerings, our educational content and our teaching methods. Any inability to track and respond to these changes in a timely and cost-effective manner would make our education services less attractive to students, which may materially and adversely affect our reputation and ability to continue to attract students without a significant decrease in our tuition. In addition, as we further expand our course offerings, we cannot assure that we will be able to adapt our existing educational content and methods to new courses that we have limited experience in teaching.

We may face risks associated with the installment tuition payment plan we offer to our students.

In 2015, we launched an installment payment option enabling eligible students to obtain loans from accredited third-party credit providers in China to finance all or part of their tuition. The third-party credit providers are responsible for performing credit assessment, approving loan applications, providing the funds, and collecting delinquent loan payments. Under the loan agreement between the borrowing student and the lending credit provider, the borrowing student is obligated to repay the loan principal in installments over a period ranging from three to 12 months. Under the cooperation agreement between us and each credit provider, we are obligated to pay the full amount of interest payable under a loan, as financial service fees, to the credit provider. We generally do not provide any guarantees for the repayment of student loans in favor of the credit providers. In 2015, 2016 and 2017, 4.8%, 32.3% and 72.9%, respectively, of our gross billings were received from third-party credit providers. For the same periods, we made interest payments of RMB2.0 million, RMB20.2 million and RMB106.2 million (US$16.3 million), respectively, to the credit providers.

As part of our long-term sales and marketing strategy, we plan to continue to make the interest payments for our students under their loans and pay service fees to the credit providers, which may place significant strains on our financial resources as our student enrollments continue to grow. We may be subject to risks associated with an increase in interest rates to the extent that we continue to make interest payments for the loans taken by our students. If we cease to do so due to increases in interest rates or for other reasons, our course packages may become more costly for our students to purchase, which could in turn negatively impact our business, financial condition and reputation.

The availability of funding from our existing and potential credit providers depends on many factors, such as their liquidity and capital sufficiency, the legal and regulatory environment, the general economic conditions, default rates of our students on the loans, and, where applicable, the availability of lenders on the credit providers’ platforms. In addition, our credit providers may seek to acquire borrowers independently instead of through cooperation with us. We currently work with a limited number of credit providers and we cannot assure you that our credit providers will continue to cooperate with us on commercially favorable terms, or at all, or that existing or potential credit providers will be able to provide loans in a sufficient amount to meet our students’ borrowing needs. If any of these were to occur, our course packages may become less compelling to prospective students who wish to obtain student loans, and as a result our business and financial condition may be negatively affected.

Disruption to or failures of our IT infrastructure could reduce student satisfaction and could harm our operations.

The performance and reliability of our IT infrastructure is critical to our operations and reputation. We provide our course offerings and educational content to our students and faculty primarily through our

26

applications and platforms built upon Genesis, our proprietary IT infrastructure. In addition, our employees, including our faculty and sales and marketing personnel, rely on our integrated IT infrastructure to carry out their marketing, sales, operation and teaching functions. As part of their educational experience, our students interact with their peers and our faculty via our platforms on a frequent basis. Accordingly, any errors, defects, disruptions or other performance problems with our IT infrastructure could damage our reputation, decrease student satisfaction and retention, adversely impact our ability to attract new students and expand our course offerings, and materially disrupt our operations. If any of these occur, our business operations, reputation and prospects could be harmed.

Our business depends on the continued success of our brand “Sunlands,” and if we fail to maintain and enhance recognition of our brand, we may face difficulty enrolling new students, and our reputation and operating results may be harmed.

We believe that market awareness of our brand “Sunlands” has contributed significantly to the success of our business. Maintaining and enhancing our brand are critical to our efforts to grow our student enrollments and gross billings. Failure to maintain and enhance our brand recognition could have a material and adverse effect on our business, operating results and financial condition. We have devoted significant resources to our brand promotion efforts in recent years, but we cannot assure you that these efforts will be successful. If we are unable to further enhance our brand recognition, or if we incur excessive marketing and promotion expenses, or if our brand image is negatively impacted by any negative publicity, our business and results of operations may be materially and adversely affected.

Students may decide not to continue taking our courses for a number of reasons, including a perceived lack of improvement in their academic performance or general dissatisfaction with our course and educational content offerings, which may adversely affect our business, financial condition, results of operations and reputation.

The success of our business depends on our ability to deliver high-quality learning experiences and help students achieve their learning objectives. We may not always be able to meet our students’ expectations in terms of academic performance due to a variety of reasons, many of which are outside of our control. We may face increased dropout rates and student dissatisfaction due to our students’ perceptions of our failure to help them achieve their anticipated academic goals, our students’ overall dissatisfaction with the quality of our course and educational content offerings and our faculty, as well as changing views of the value of the diplomas, degrees and qualifications they are pursuing through taking our courses. These factors may contribute to reduced student engagement and increased challenges in attracting and enrolling prospective students, all of which may adversely affect our prospects, business, financial condition, results of operations and reputation.

We face risks associated with our reliance on our STE course offerings, including risks resulting from changes in government policies or requirements relating to STE exams.

Our course offerings are concentrated to our STE course offerings, namely post-secondary courses designed for students pursuing associate diplomas or bachelor’s degrees by taking the STE exams. STE course offerings represent a significant portion of our net revenues, gross billings and new student enrollments. Our STE course offerings accounted for approximately 57.4%, 66.3% and 80.6%, respectively, of our net revenues and approximately 71.0%, 79.0% and 89.2%, respectively, of our gross billings in 2015, 2016 and 2017. During the same periods, our STE course offerings accounted for approximately 55.4%, 61.7% and 80.1%, respectively, of our new student enrollments.

Our reliance on STE course offerings may expose us to concentration risks. If there are significant reductions in the perceived value of degrees or diplomas our students are pursuing through the STE exams, or if the PRC government releases substantial updates to the requirements or formats of the STE exams and we are unable to upgrade our course or educational content offerings to address such developments in a timely manner,

27

the demand for and attractiveness of our STE course offerings may be adversely affected, which could have an adverse impact on our financial condition and results of operations.

If we fail to effectively identify, pursue and consummate strategic alliances or acquisitions, our ability to grow and to achieve profitability could be impacted.

We may from time to time engage in evaluations of, and discussions with, possible domestic and international acquisition or alliance candidates. We may not be able to identify suitable strategic alliances or acquisition opportunities, complete such transactions on commercially favorable terms, or successfully integrate business operations, infrastructure and management philosophies of acquired businesses and companies. There may be particular complexities, regulatory or otherwise, associated with our expansion into new markets, and our strategies may not succeed beyond our current markets. If we are unable to effectively address these challenges, our ability to execute acquisitions as a component of our long-term strategy will be impaired, which could have an adverse effect on our growth.

We face intense competition in our industry, which could divert student to our competitors, lead to pricing pressure and loss of market share, and significantly reduce our gross billings and net revenues.

China’s post-secondary and professional education market is intensely competitive. We compete with other online education service providers or traditional offline players, for student enrollments and engagement, high-quality academic and administrative faculty, and sales and marketing personnel, among other things. Some of our current and future competitors may have substantially greater name recognition and financial and other resources than we do, which may enable them to compete more effectively for potential students and decrease our market share. We also expect to face competition as a result of new entrants to the post-secondary and professional education market.

We may not be able to compete successfully against current or future competitors and may face competitive pressures that could adversely affect our business or results of operations. For example, increased competition may result in pricing pressure for us in terms of the tuition we are able to negotiate to receive from a student. In addition, online education is characterized by rapid changes in students’ technological requirements and expectations and evolving market standards, and our competitors may develop platforms or other technologies that are superior to the platform and technology we use. These differences may affect our ability to recruit and retain students, which may render our online delivery format less competitive. The increasingly competitive landscape may also result in longer and more complex sales cycles with a prospective student or a decrease in our market share, any of which could negatively affect our gross billings and net revenues and our ability to grow our business.

If our security measures are breached or fail and result in unauthorized disclosure of data by our employees or our third-party agents, we could lose existing students, fail to attract new students and be exposed to protracted and costly litigation.

Maintaining platform security is of critical importance to our students because the platform stores and transmits proprietary and confidential information, which may include sensitive personally identifiable information that may be subject to stringent legal and regulatory obligations. As an online education service provider, we face an increasing number of threats to our IT infrastructure, including unauthorized activity and access by our employees or third-party agents, system viruses, worms, malicious code and organized cyberattacks, which could breach our security and disrupt our business. For example, we have introduced data security and confidentiality protocols into the cooperation agreements we enter into with third-party sales agents with whom we share prospective students’ contact information, and we have made technical improvements in our IT infrastructure to prevent unauthorized access of confidential or sensitive personal information by our employees and third-party sales agents in the process of engaging prospectus students. These measures, however, may not be as effective as we anticipate. In addition, there is no assurance that our third-

28

party sales agents will comply with contractual and legal requirements with respect to data privacy when they collect data from our prospective students. If our security measures are breached or fail as a result of third-party action, employee error, malfeasance or otherwise, we could be subject to liability or our business could be interrupted, potentially over an extended period of time. Any or all of these issues could harm our reputation, adversely affect our ability to attract and enroll prospective students, cause prospective students not to enroll or stay enrolled, or subject us to third-party lawsuits, regulatory fines or other action or liability. Further, any reputational damage resulting from breach of our security measures could create distrust of our company by prospective students or investors. We may be required to expend significant additional resources to protect against the threat of these disruptions and security breaches or to alleviate problems caused by such disruptions or breaches.

Privacy concerns could limit our ability to collect and leverage our user data and disclosure of user data could adversely impact our business and reputation.

In the ordinary course of our business and in particular in connection with conducting sales and marketing activities with our existing and prospective students, we collect and utilize data supplied by our users. We currently face certain legal obligations regarding the manner in which we treat such information. Increased regulation of data utilization practices, including self-regulation or findings under existing laws that limit our ability to collect, transfer and use data, could have an adverse effect on our business. In addition, if we were to disclose data about our users in a manner that was objectionable to them, our business reputation could be adversely affected, and we could face potential legal claims that could impact our operating results. Internationally, we may become subject to additional and/or more stringent legal obligations concerning our treatment of customer and other personal information, such as laws regarding data localization and/or restrictions on data export. Failure to comply with these obligations could subject us to liability, and to the extent that we need to alter our business model or practices to adapt to these obligations, we could incur additional expenses.

Tuition refunds or potential refund disputes may negatively affect our cash flow, financial condition, and reputation.

We offer different tuition refund options to our students depending on the time of enrollment and subject to certain conditions and restrictions in the service contract between us and each of our students. Generally, a student is offered a full, unconditional refund within 24 hours upon enrollment. If the student makes a refund request after taking at least one trial course lasting 30 minutes by reason of any material academic issue of our courses within certain refund period, we would offer such student a partial refund excluding the registration fees and the relevant academic fees for the trial lesson upon our confirmation. In addition, at our discretion, a partial refund may also be granted to the student who withdraws at any other time during his or her enrollment, subject to special approval by us. When calculating gross billings for a specific period, we deduct the total amount of refunds from the total amount of cash received for the sale of course packages for such period. See “Business—Our Tuition and Fees.”

In 2015, 2016 and 2017, we had made RMB53.7 million, RMB61.3 million and RMB150.1 million (US$23.1 million) of refund payments, respectively. The number of refund requests and the amount of refunds could be affected by a number of factors, many of which are beyond our control. These factors include, without limitation to, student dissatisfaction with our teaching quality and our course and educational content offerings, privacy concerns relating to our online platforms, negative publicity regarding us or online education in general, and any change or development in PRC laws and regulations with respect to fees and tuitions charged by online education providers like us. See “We face risks associated with our lack of private school operating permit for our online education services as well as uncertainties surrounding PRC laws and regulations governing the education industry, including the Law for Promoting Private Education and its Implementing Rules. ”Any refund payments that we may be required to make to our students, as well as the expenses we could incur for processing refunds and resolving refund disputes, could be substantial and could adversely affect our gross billings, net revenues, liquidity and financial condition. A high volume of refunds and refund disputes may also generate

29

negative publicity that could harm our reputation. We have experienced in the past, and may experience in the future, negative publicity in relation to refund disputes between us and our students, which may significantly harm our brand name and divert our attention from operating our business.

Our success depends on the continuing efforts of our senior management team and other key employees.

We depend on the continued contributions of our senior management and other key employees, including, in particular, Mr. Jianhong Yin, also known as Peng Ou, our founder and the chairman of our Board of Directors, and Mr. Tongbo Liu, our director and Chief Executive Officer. The loss of the services of any of our senior management or other key employees could harm our business. Competition for qualified talents in China is intense. If one or more of our senior management or other key employees are unable or unwilling to continue in their present positions, we may not be able to find replacements in a timely manner, or at all, and our business may be disrupted. Moreover, if any member of our senior management team or any of our other key personnel joins a competitor or forms or invests in a competing business, we may lose student enrollments, qualified teaching faculty members and other key sales and marketing personnel to our competitors. Our future success is also dependent on our ability to attract a significant number of qualified employees and retain existing key employees. If we are unable to do so, our business and growth may be materially and adversely affected. Our need to significantly increase the number of our qualified employees and retain key employees may cause us to materially increase compensation-related costs, including share-based compensation.

If we cannot maintain our corporate culture as we grow, we could lose the innovation, collaboration and focus that contribute to our business.

We believe that a critical component of our success is our corporate culture, which fosters innovations and has roots in a deep understanding of our students and the evolving education industry in China. As we continue to expand and grow our business, we may find it difficult to maintain these valuable aspects of our corporate culture. Any failure to preserve our culture could undermine our reputation in the marketplace and negatively impact our ability to attract and retain employees and students, which would in turn jeopardize our future success.

We may from time to time be subject to infringement claims relating to intellectual properties of third parties.

We cannot assure you that our course offerings and educational contents and our IT technologies and platforms do not or will not infringe upon copyrights or other intellectual property rights held by third parties. We may encounter disputes from time to time over rights and obligations concerning intellectual properties, and we may not prevail in those disputes.

We have adopted policies and procedures to prohibit our students and employees from infringing upon third-party copyright or intellectual property rights. However, we cannot ensure that they will not, against our policies, use third-party copyrighted materials or intellectual property without proper authorization in our classes or via any medium through which we provide our services. We may incur liability for unauthorized duplication or distribution of materials posted on our websites or used in our classes. We have been involved in claims against us alleging our infringement of third-party intellectual property rights and we may be subject to such claims in the future. For example, our quiz banks designed for students pursuing the STE exams contain a pool of over 973,000 quizzes as of December 31, 2017, and we have not entered into any licensing arrangements with, or otherwise obtained any consent from, the government agencies administering the STE exams for using these questions. Although we have never been subject to any legal or administrative penalties or proceedings relating to our use of these sample questions, we cannot assure you that we will not be subject to infringement claims associated with our use of real STE questions in the future. Any such intellectual property infringement claim could result in costly litigation and divert our management attention and resources, which in turn could negatively affect our business, financial condition and prospect.

30

If we fail to protect our intellectual property rights, our brand and business may suffer.

We rely on a combination of patent, copyright, trademark and trade secret laws and restrictions on disclosure to protect our intellectual property rights. Although we seek to obtain copyright or patent protection for our intellectual property when applicable, it is possible that we may not be able to do so successfully or that the copyright or patent we have obtained may not be sufficient to protect all of our intellectual property rights. In particular, we rely, to the great extent, upon our educational content developed in-house, including course syllabi and outlines, quiz banks, teaching notes, and learning outcomes trees, to provide high-quality online education services. Despite our efforts to protect our proprietary education contents and other intellectual property rights, unauthorized parties may attempt to copy or duplicate our intellectual property or otherwise use our intellectual properties without obtaining our consent. Monitoring unauthorized use of our intellectual property is difficult and costly, and we cannot be certain that the steps we have taken will effectively prevent misappropriation of our intellectual properties. If we are not successful in protecting our intellectual property rights, our business and results of operations may be adversely affected.

Our students, employees and third-party vendors may engage in intentional or negligent misconduct or other improper activities or misuse our platform, which could harm our brand and reputation.

We are exposed to the risk of fraud or other misconducts committed by our students, employees and vendors, including certain third-party sales and marketing agencies. For example, in some instances, our students and our faculty members may post to our platform articles or other third-party content for use in class discussions. The PRC laws governing the fair use of these third-party materials are imprecise and adjudicated on a case-by-case basis, which makes it challenging for us to adopt and implement policies governing these practices. We could, as a result, incur liability to third parties for the unauthorized duplication, distribution or other use of these materials. Any such claims could subject us to costly litigation and impose a significant strain on our financial resources and attention of management personnel regardless of whether the claims have merit. Additionally, we may be required to alter or cease our uses of such materials, which may include changing or removing content from courses or altering the functionality of our platform, or to pay monetary damages. Fraud or other misconducts by our students, employees or third parties may also involve engaging in unauthorized misrepresentation to our potential students and misappropriating third-party intellectual property and other propitiatory rights during marketing activities, misusing sensitive personal information of our students, and engaging in bribery or other unlawful payments, any of which could result in customer complaints, regulatory and legal liabilities, as well as serious harm to our brand and reputation.

We may be the subject of detrimental conduct by third parties such as our competitors, including complaints to regulatory agencies and the public dissemination of malicious assessments of our business, which could have a negative impact on our reputation and cause us to lose market share, students and revenues, and adversely affect the price of our ADSs.

We have been, and in the future may be, the target of anti-competitive, harassing or other detrimental conduct by third parties including our competitors. Such conduct may include complaints, anonymous or otherwise, to regulatory agencies regarding our operations, accounting, business relationships, business prospects and business ethics. Additionally, allegations, directly or indirectly against us, may be posted online by anyone, whether or not related to us, on an anonymous basis. We may be subject to government or regulatory investigation as a result of such third-party conduct and may be required to expend significant time and incur substantial costs to address such third-party conduct, and there is no assurance that we will be able to conclusively refute each of the allegations within a reasonable period of time, or at all. Our reputation may also be materially negatively affected as a result of the public dissemination of anonymous allegations or malicious statements about our business, which in turn may cause us to lose students and revenues, and adversely affect the price of our ADSs.

31

Our user metrics and other estimates are subject to inaccuracy in measuring our operating performance, which may harm our reputation.

We continually review number of students, new student enrollments, gross billings per new student enrollment, and other operating metrics to evaluate growth trends, measure our performance and make strategic decisions. These metrics are calculated using internal data, have not been validated by an independent third party and may not be indicative of our future operating performance. While these numbers are based on what we believe to be reasonable estimates for the applicable period of measurement, there are inherent challenges in measuring how our website and mobile application are used across a large student base. For example, we may not be able to identify individual students who have multiple accounts from multiple students who share one account on our website or mobile application. In addition, we collect student reviews to measure student satisfaction rate and other student engagement metrics, but these reviews may not be representative of our entire student population. Errors or inaccuracies in our metrics or data could result in incorrect business decisions and inefficiencies. For instance, if a significant understatement or overstatement of student satisfaction or student acquisition costs were to occur, we might expend resources to implement unnecessary business measures or fail to take required actions to remedy an unfavorable trend. If investors do not perceive our operating metrics to accurately represent our operating performance, or if we discover material inaccuracies in our operating metrics, our reputation may be harmed.

If we fail to implement and maintain an effective system of internal controls, we may be unable to accurately or timely report our results of operations or prevent fraud, and investor confidence and the market price of our ADSs may be materially and adversely affected.

Prior to this offering, we were a private company with limited accounting personnel and other resources with which to address our internal controls and procedures. Our management has not completed an assessment of the effectiveness of our internal control over financial reporting, and our independent registered public accounting firm has not conducted an audit of our internal control over financial reporting. In the course of auditing our consolidated financial statements as of December 31, 2017 and for the year ended December 31, 2017, we and our independent registered public accounting firm identified two material weaknesses in our internal control over financial reporting and other control deficiencies as of December 31, 2017. 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 the company’s annual or interim financial statements will not be prevented or detected on a timely basis. The material weaknesses identified relate to (i) the lack of sufficient financial reporting and accounting personnel with appropriate knowledge of U.S. GAAP, and (ii) lack of comprehensive accounting policies and procedures manual in accordance with U.S. GAAP. We have taken measures and plan to continue to take measures to remedy these material weaknesses. For details, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Internal Control over Financial Reporting.” The implementation of these measures may not fully address the material weaknesses in our internal control over financial reporting, and we cannot conclude that they have been fully remedied. Our failure to correct theses material weaknesses or our failure to discover and address any other material weaknesses could result in inaccuracies in our financial statements and could also impair our ability to comply with applicable financial reporting requirements and related regulatory filings on a timely basis.

Upon the completion of this offering, we will become a public company in the United States subject to the Sarbanes-Oxley Act of 2002. Section 404 of the Sarbanes-Oxley Act of 2002, or Section 404, will require that we include a report from management on our internal control over financial reporting in our annual report on Form 20-F beginning with our annual report for the fiscal year ending December 31, 2018. 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

32

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

During the course of documenting and testing our internal control procedures, in order to satisfy the requirements of Section 404, we may identify 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. Generally speaking, 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 will incur increased costs as a result of being a public company, particularly after we cease to qualify as an “emerging growth company.”

Upon completion of this offering, we will become a public company and expect to incur significant legal, accounting and other expenses that we did not incur as a private company. The Sarbanes-Oxley Act of 2002, as well as rules subsequently implemented by the SEC and the New York Stock Exchange, impose various requirements on the corporate governance practices of public companies. As a company with less than US$1.07 billion in revenues for our last fiscal year, we qualify as an “emerging growth company” pursuant to the JOBS Act. An emerging growth company may take advantage of specified reduced reporting and other requirements that are otherwise applicable generally to public companies. These provisions include exemption from the auditor attestation requirement under Section 404 of the Sarbanes-Oxley Act of 2002, or Section 404, in the assessment of the emerging growth company’s internal control over financial reporting. The JOBS Act also permits an emerging growth company to delay adopting new or revised accounting standards until such time as those standards apply to private companies. However, we have elected to “opt out” of this provision and, as a result, we will comply with new or revised accounting standards as required when they are adopted for public companies. This decision to opt out of the extended transition period under the JOBS Act is irrevocable.

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

We have granted, and may continue to grant, share incentives, which may result in increased share based compensation expenses.

We adopted an equity incentive plan in October 2017, or the 2017 Plan, for the purpose of granting share based compensation awards to employees, officers, directors and consultants to incentivize their performance and promote the success of our business.

We account for compensation costs for all share-based awards using a fair-value based method and recognize expenses in our consolidated statements of operations in accordance with U.S. GAAP. Under the 2017 Plan, we are authorized to grant options, restricted stock units and other types of awards the administrator of the 2017 Plan decides. Under the 2017 Plan, the maximum aggregate number of shares which may be issued pursuant to all awards is 483,846 shares. As of the date of this prospectus, options to purchase a total of 60,826 ordinary shares were outstanding under the 2017 Plan. We believe the granting of share-based awards is of significant importance to our ability to attract and retain key personnel and employees, and we will continue to grant share-based awards in the future. As a result, our expenses associated with share-based compensation may increase, which may have an adverse effect on our results of operations.

Failure to 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 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 requirement of employee benefit plans has not been implemented consistently by the local governments in China given the different levels of economic development in different locations. Our failure in making contributions to various employee benefit plans and in complying with applicable PRC labor-related laws may subject us to late payment penalties, and we could be required to make up the contributions for these plans as well as to pay late fees and fines. If we are subject to late fees or fines in relation to the underpaid employee benefits, our financial condition and results of operations may be adversely affected. In addition, to the extent that we can make a reasonable estimate of the liability arising from our failure in making full contributions to various employee benefit plans, we record a related contingent liability. However, the amount of our estimates may be inaccurate, in which case our financial condition and cash flow may be adversely affected if we were to pay late fees or fines in relation to the underpaid employee benefits.

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

The currently effective PRC Labor Contract Law was first adopted on June 29, 2007 and later amended on December 28, 2012. The PRC Labor Contract Law has reinforced the protection of employees who, under the PRC Labor Contract Law, have the right, among others, to have written employment contracts, to enter into employment contracts with no fixed term under certain circumstances, to receive overtime wages and to terminate or alter terms in labor contracts. Furthermore, the PRC Labor Contract Law sets forth additional restrictions and increases the costs involved with dismissing employees. To the extent that we need to significantly reduce our workforce, the PRC Labor Contract Law could adversely affect our ability to do so in a timely and cost-effective manner, and our results of operations could be adversely affected. In addition, for employees whose employment contracts include noncompetition terms, the PRC Labor Contract Law requires us to pay monthly compensation after such employment is terminated, which will increase our operating expenses.

In addition, we are required by PRC laws and regulations to make social insurance registration and open housing fund account with relevant governmental authorities and 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. The relevant

34

government agencies may examine whether an employer has made adequate payments of the requisite statutory employee benefits, and those employers who fail to make adequate payments may be subject to late payment fees, fines and/or other penalties. If we fail to make adequate social insurance and housing fund contributions, we may be subject to fines and legal sanctions, and our business, financial condition and results of operations may be adversely affected. We expect that our labor costs, including wages and employee benefits, will continue to increase. Unless we are able to pass on these increased labor costs to our customers by increasing the prices of our products and services, our financial conditions and results of operations would be materially and adversely affected.

We face certain risks relating to the real properties that we lease.

We lease real properties from third parties primarily for our office use in China, and the lease agreements for most of these leased 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 were 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 approximately 125 of our lease agreements that have not been registered with the relevant PRC governmental authorities.

As of the date of this prospectus, we are not aware of any regulatory or governmental actions, claims or investigations being contemplated or any challenges by third parties to our use of our leased properties the lease agreements of which have not been registered with the government authorities. However, we cannot assure you that the government authorities will not imposed fines on us due to our failure to register any of our lease agreements, which may negatively impact our financial condition.

We lease real properties from third parties in China for marketing and providing offline consultation related to our online services for potential students or existing students. Some of the ownership certificates or other similar proof of certain 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 operations in a timely manner, our operations may be interrupted.

Our operations depend on the performance of the internet infrastructure and telecommunications networks in China.

The successful operation of our business depends on the performance of the internet infrastructure and telecommunications networks in China. Almost all access to the internet is maintained through state-owned telecommunications operators under the administrative control and regulatory supervision of the MIIT. Moreover, we have entered into contracts with various subsidiaries of a limited number of telecommunications service providers at provincial level and rely on them to provide us with data communications capacity through local telecommunications lines. We have limited access to alternative networks or services in the event of disruptions, failures or other problems with China’s internet infrastructure or the telecommunications networks provided by telecommunications service providers. Our platform regularly serves a large number of users and advertisers. With the expansion of our business, we may be required to upgrade our technology and infrastructure

35

to keep up with the increasing traffic on our platform. However, we have no control over the costs of the services provided by telecommunications service providers. If the prices we pay for telecommunications and internet services rise significantly, our results of operations may be materially and adversely affected. If internet access fees or other charges to internet users increase, our user traffic may decline and our business may be harmed.

We currently do not have any business insurance coverage.

Insurance companies in China currently do not offer as extensive an array of insurance products as insurance companies in more developed economies. Currently, we do not have any business liability or disruption insurance to cover our operations. We have determined that the costs of insuring for these risks and the difficulties associated with acquiring such insurance on commercially reasonable terms make it impractical for us to have such insurance. Any uninsured business disruptions may result in our incurring substantial costs and the diversion of resources, which could have an adverse effect on our results of operations and financial condition.

We face risks related to natural disasters, extreme weather conditions, health epidemics and other catastrophic incidents, which could significantly disrupt our operations.

China has in the past experienced significant natural disasters, including earthquakes, extreme weather conditions, as well as health scares related to epidemic diseases, and any similar event could materially impact our business in the future. If a disaster or other disruption were to occur in the future that affects the regions where we operate our business, our operations could be materially and adversely affected due to loss of personnel and damages to property. Even if we are not directly affected, such a disaster or disruption could affect the operations or financial condition of our ecosystem participants, which could harm our results of operations.

In addition, our business could be affected by public health epidemics, such as the outbreak of avian influenza, severe acute respiratory syndrome, or SARS, Zika virus, Ebola virus or other disease. If any of our employees is suspected of having contracted a contagious disease, we may be required to apply quarantines or suspend our operations. Furthermore, any future outbreak may restrict economic activities in affected regions, resulting in reduced business volume, temporary closure of our offices or otherwise disrupt our business operations and adversely affect our results of operations.

Risks Related to Our Corporate Structure

If the PRC government finds that the agreements that establish the structure for operating some of our operations in China do not comply with PRC regulations relating to 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 investment in the value-added telecommunication services industry in China is extensively regulated and subject to numerous restrictions. Pursuant to the Foreign Investment Industries Guidance Catalog (2017 Revisions), or the Guidance Catalog, with a few exceptions, foreign investors are not allowed to own more than 50% of the equity interests in a value-added telecommunication service provider and any such foreign investor must have experience in providing value-added telecommunications services overseas and maintain a good track record.

We are a Cayman Islands company and our wholly-owned PRC subsidiaries are currently considered foreign-invested enterprise. Accordingly, our PRC subsidiaries are not eligible to provide value-added telecommunication services in China. To ensure strict compliance with the PRC laws and regulations, we conduct such business activities through Beijing Sunlands, our consolidated variable interest entity, or VIE, and its subsidiaries. Wuhan Zhibo, our wholly owned subsidiary in China, has entered into a series of contractual arrangements with our VIE, its shareholders and certain of our VIE’s subsidiaries, which enable us to (i) exercise

36

effective control over our VIE, (ii) receive substantially all of the economic benefits of our VIE, and (iii) have an exclusive option to purchase all or part of the equity interests and assets 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 its financial results as our VIE under U.S. GAAP. See “Corporate History and Structure” for further details.

If the PRC government finds that our contractual arrangements do not comply with its restrictions on foreign investment in the value-added telecommunication services, or if the PRC government otherwise finds that we, our VIE, or any of its subsidiaries are in violation of PRC laws or regulations or lack the necessary permits or licenses to operate our business, the relevant PRC regulatory authorities, including the MIIT and SAIC, would have broad discretion in dealing with such violations or failures, including, without limitation:

Any of these actions could cause significant disruption to our business operations and severely damage our reputation, which would in turn materially and adversely affect our business, financial condition and results of operations. If any of these occurrences results in our inability to direct the activities of our VIE that most significantly impact its economic performance and/or our failure to receive the economic benefits from our VIE, we may not be able to consolidate the entity in our consolidated financial statements in accordance with U.S. GAAP.

Our business may be significantly affected by the Draft Foreign Investment Law, if implemented as proposed.

On January 19, 2015, the PRC Ministry of Commerce, or MOFCOM, published the Draft Foreign Investment Law. At the same time, MOFCOM published an accompanying explanatory note of the draft Foreign Investment Law, which contains important information about the draft Foreign Investment Law, including its drafting philosophy and principles, main table of contents, plans to transition to the new legal regime and treatment of business in China controlled by foreign invested enterprises. The Draft Foreign Investment Law proposes significant changes to the PRC foreign investment legal regime and, when implemented, may have a significant impact on businesses in China controlled by foreign invested enterprises primarily through contractual arrangements, such as our business. Please refer to “Regulation—Regulations Relating to Foreign Investment” for further details. MOFCOM solicited comments on the Draft Foreign Investment Law in 2015, but no new draft has been published since then. There is substantial uncertainty with respect to its final content, interpretation, adoption timeline and effective date. It is anticipated, however, that the draft Foreign Investment Law will reflect regulations on variable interest entities. MOFCOM suggests both registration and approval as potential options for the regulation of variable interest entity structures, depending on whether they are “Chinese” or “foreign controlled.” One of the core concepts of the draft Foreign Investment Law is “de facto control,” which emphasizes substance over form in determining whether an entity is “Chinese” or “foreign-controlled. ” “Chinese investors” are individuals who are Chinese nationals, Chinese government agencies and any domestic enterprise controlled by Chinese nationals or government agencies. “Foreign investors” are foreign citizens, foreign governments, international organizations and entities controlled by foreign citizens and entities.

37

It is unclear whether our current corporate structure will be considered “Chinese” under the scheme of the Draft Foreign Investment Law, though the fact that two Chinese nationals, Mr. Peng Ou and Mr. Tongbo Liu, jointly own a majority of our outstanding shares increases the likelihood that we will be treated as a Chinese controlled company. In the event that our contractual arrangements under which we operate our value-added telecommunication services are not treated as a domestic investment and/or our operation of online education services are classified as a “prohibited business” in the Prohibited List under the Draft Foreign Investment Law when officially enacted, such contractual arrangements may be deemed as invalid and illegal and we may be required to unwind the contractual arrangements and/or dispose of such business.

We rely on contractual arrangements with our VIE and its shareholders for a large portion of our business operations 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 Beijing Sunlands, or our VIE, its shareholders and certain of its subsidiaries to operate our online education services business in China. These contractual arrangements may not be as effective as direct ownership in providing us with control over our VIE. For example, our VIE and its shareholders could breach their contractual arrangements with us by, among other things, failing to conduct their operations in an acceptable manner or taking other actions that are detrimental to our interests. The revenues contributed by our VIE and its subsidiaries constituted substantially all of our net revenues in 2015, 2016 and 2017.

If we had direct ownership of our VIE, 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. The shareholders of our consolidated VIE may not act in the best interests of our company or may not perform their obligations under these contracts. Such risks exist throughout the period in which we intend to operate certain portions of our business through the contractual arrangements with our VIE. If any disputes relating to these contracts remain 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. Therefore, our contractual arrangements with our VIE may not be as effective in ensuring our control over the relevant portion of our business operations as direct ownership would be.

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 claiming damages, which we cannot assure will be effective under PRC law. For example, if the shareholders of our VIE refuse to transfer their equity interest in our VIE to us or our designee if we exercise the purchase option pursuant to these contractual arrangements, or if they otherwise act in bad faith toward us, then we may have to take legal actions to compel them to perform their contractual obligations. In addition, if any third parties claim any interest in such shareholders’ equity interests in our VIE, our ability to exercise shareholders’ rights or foreclose the share pledge according to the contractual arrangements may be impaired. If these or other disputes between the shareholders of our VIE and third parties were to impair our control over our VIE, our ability to consolidate the financial results of our VIE would be affected, which would in turn result in a material adverse effect on our business, operations and financial condition.

38

Our contractual arrangements are governed by PRC law. Accordingly, these contracts would be interpreted in accordance with PRC law, and any disputes would be resolved in accordance with PRC legal procedures.

The legal system in the PRC is not as developed as in some other jurisdictions, such as the United States. As a result, uncertainties in the PRC legal system could limit our ability to enforce these contractual arrangements. Meanwhile, there are very few precedents and little formal guidance as to how contractual arrangements in the context of a VIE should be interpreted or enforced under PRC law. There remain significant uncertainties regarding the ultimate outcome of such arbitration should legal action become 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, which would require additional expenses and delay. In the event we are unable to enforce these contractual arrangements, or if we suffer significant delays 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 our business may be negatively affected.

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

The shareholders of our VIE may have actual or potential conflicts of interest with us. These shareholders may refuse to sign or 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 it. For example, the shareholders may be able to cause our agreements with our VIE to be performed in a manner adverse 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. If we cannot resolve any conflict of interest or dispute between us and these shareholders, 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.

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

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

We may lose the ability to use, or otherwise benefit from, the licenses, approvals and assets held by our VIE, which could severely disrupt our business, render us unable to conduct some or all of our business operations and constrain our growth.

As part of our contractual arrangements with our VIE, our VIE holds certain assets, licenses and permits that are material to our business operations, such as the ICP License and the License for the Production and Operation

39

of Radio and Television Program. The contractual arrangements contain terms that specifically obligate VIE’s shareholders to ensure the valid existence of the VIE and restrict the disposal of material assets of the VIE. However, in the event the VIE’s shareholders breach the terms of these contractual arrangements and voluntarily liquidate our VIE, or our VIE declares bankruptcy and all or part of its assets become subject to liens or rights of third-party creditors, or are otherwise disposed of without our consent, we may be unable to conduct some or all of our business operations or otherwise benefit from the assets held by the VIE, which could have a material adverse effect on our business, financial condition and results of operations. Furthermore, if our VIE undergoes a voluntary or involuntary liquidation proceeding, its shareholders or unrelated third-party creditors may claim rights to some or all of the assets of the VIE, thereby hindering our ability to operate our business as well as constrain our growth.

Certain of our existing shareholders have substantial influence over our company, and their interests may not be aligned with the interests of our other stockholders.

Mr. Peng Ou, our founder and the chairman of our Board of Directors, owns approximately 42.7% of our voting power and Mr. Tongbo Liu, our director and our Chief Executive Officer, owns approximately 16.5% of our voting power as of the date of this prospectus, on a fully diluted basis. In addition, immediately upon the completion of this offering, Mr. Peng Ou, Mr. Tongbo Liu and certain of our senior management and employees will collectively beneficially own all of our issued and outstanding Class C ordinary shares which will constitute approximately             % of the aggregate voting power of our total issued and outstanding share capital immediately upon the completion of this offering, assuming the underwriters do not exercise their over-allotment option, and the issuance of sale of Class A ordinary shares in connection with concurrent private placements by Orchid Asia and New Oriental. In addition, upon the completion of this offering, up to 120,394 ordinary shares reserved and issuable upon the exercise of options granted pursuant to our equity incentive plan adopted in October 2017 shall be, upon issuance of such ordinary shares, designated as Class C ordinary shares, the voting power of which will be held by certain of our senior employees. See “ - Risks Related to the ADSs and This Offering - Our triple-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.” As a result, Mr. Peng Ou, Mr. Tongbo Liu and certain of our senior management and employees have significant influence over our business, including decisions regarding mergers, consolidations, liquidations and the sale of all or substantially all of our assets, election of directors and other significant corporate actions. This concentration of ownership may also have the effect of discouraging, delaying or preventing a future change of control, which could deprive our stockholders of an opportunity to receive a premium for their shares as part of a sale of our company and might reduce the price of our ADSs.

Risks Related to Doing Business in China

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

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

40

While the Chinese economy has experienced significant growth over past decades, growth has been uneven, both geographically and among various sectors of the economy. Any adverse changes in economic conditions in China, in the policies of the Chinese government or in the laws and regulations in China could have a material adverse effect on the overall economic growth of China. Such developments could adversely affect our business and operating results, lead to a reduction in demand for our services 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. For example, our financial condition and results of operations may be adversely affected by government control over capital investments or changes in tax regulations. In addition, in the past the Chinese government has implemented certain measures, including interest rate adjustment, to control the pace of economic growth. These measures may cause decreased economic activity in China, which may adversely affect our business and operating results.

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

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

In 1979, the PRC government began to promulgate a comprehensive system of laws and regulations governing economic matters in general. The overall effect of legislation 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. In particular, the interpretation and enforcement of these laws and regulations involve uncertainties. Since PRC administrative and court authorities have significant discretion in interpreting and implementing statutory provisions and contractual terms, it may be difficult to evaluate the outcome of administrative and court proceedings and the level of legal protection we enjoy. These uncertainties may affect our judgment on the relevance of legal requirements and our ability to enforce our contractual rights or tort claims. In addition, the regulatory uncertainties may be exploited through unmerited or frivolous legal actions or threats in attempts to extract payments or benefits from us.

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

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

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

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

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

41

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

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

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

In order to secure the use of our chops and seals, we have established internal control procedures and rules for using these chops and seals. In any event that the chops and seals are intended to be used, the responsible personnel will submit the application through our office automation system and the application will be verified and approved by authorized employees in accordance with our internal control procedures and rules. In addition, in order to maintain the physical security of our chops, we generally have them stored in secured locations accessible only to authorized employees. Although we monitor such authorized employees, the procedures may not be sufficient to prevent all instances of abuse or negligence. There is a risk that our employees could abuse their authority, for example, by entering into a contract not approved by us or seeking to gain control of one of our subsidiaries or consolidated VIEs. 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.

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

Any funds we transfer to our PRC subsidiary, either as a shareholder loan or as an increase in registered capital, are subject to approval by or registration with relevant governmental authorities in China. According to the relevant PRC regulations on foreign-invested enterprises, or FIEs, in China, capital contributions to our PRC subsidiaries are subject to the approval of or filing with the MOFCOM or its local branches and registration with a local bank authorized by the State Administration of Foreign Exchange, or SAFE. In addition, (i) any foreign loan procured by our PRC subsidiaries is required to be registered with SAFE or its local branches and (ii) our PRC subsidiaries may not procure loans which exceed the difference between its total investment amount and

42

registered capital. For the restriction and limitation on the amount of loans, please see “Regulation—Regulations on loans to and direct investment in the PRC entities by offshore holding companies” for details. Any medium or long-term loan to be provided by us to our VIE must be registered with the NDRC and the SAFE or its local branches. We may not be able to complete such registrations on a timely basis, with respect to future capital contributions or foreign loans by us to our PRC subsidiary. If we fail to complete such registrations, our ability to use the proceeds of this offering and to capitalize our PRC operations may be negatively affected, which could adversely affect our liquidity and our ability to fund and expand our business.

On March 30, 2015, the SAFE promulgated the Circular on Reforming the Management Approach Regarding the Foreign Exchange Capital Settlement of Foreign-Invested Enterprises, or SAFE Circular 19, which took effect as of June 1, 2015. SAFE Circular 19 launched a nationwide reform of the administration of the settlement of the foreign exchange capitals of FIEs and allows FIEs to settle their foreign exchange capital at their discretion, but continues to prohibit FIEs from using the Renminbi fund converted from their foreign exchange capital for expenditure beyond their business scopes, providing entrusted loans or repaying loans between nonfinancial enterprises. The SAFE issued the Circular on Reforming and Regulating Policies on the Control over Foreign Exchange Settlement of Capital Accounts, or SAFE Circular 16, effective in June 2016. Pursuant to SAFE Circular 16, enterprises registered in China may also convert their foreign debts from foreign currency to Renminbi on a self-discretionary basis. SAFE Circular 16 provides an integrated standard for conversion of foreign exchange under capital account items (including but not limited to foreign currency capital and foreign debts) on a self-discretionary basis which applies to all enterprises registered in China. SAFE Circular 16 reiterates the principle that Renminbi converted from foreign currency-denominated capital of a company may not be directly or indirectly used for purposes beyond its business scope or prohibited by PRC laws or regulations, while such converted Renminbi shall not be provided as loans to its non-affiliated entities. As this circular is relatively new, there remains uncertainty as to its interpretation and application and any other future foreign exchange related rules. Violations of these Circulars could result in severe monetary or other penalties. SAFE Circular 19 and SAFE Circular 16 may significantly limit our ability to use Renminbi converted from the net proceeds of this offering to fund the establishment of new entities in China by our VIE or its subsidiaries, to invest in or acquire any other PRC companies through our PRC subsidiaries, or to establish new consolidated VIEs in China, which may adversely affect our business, financial condition and results of operations.

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

The value of the Renminbi against the U.S. dollar and other currencies may fluctuate and is affected by, among other things, changes in political and economic conditions and the foreign exchange policy adopted by the PRC government. On July 21, 2005, the PRC government changed its policy of pegging the value of the Renminbi to the U.S. dollar. Following the removal of the U.S. dollar peg, the Renminbi appreciated more than 20% against the U.S. dollar over the following three years. Between July 2008 and June 2010, this appreciation halted and the exchange rate between the Renminbi and the U.S. dollar remained within a narrow band. Since June 2010, the Renminbi has started to appreciate slowly against the U.S. dollar, though there have been periods when the U.S. dollar has appreciated against the RMB. On August 11, 2015, the PBOC allowed the Renminbi to depreciate by approximately 2% against the U.S. dollar. Since then and until the end of 2016, the Renminbi has depreciated against the U.S. dollar by approximately 10%. It is difficult to predict how long such depreciation of RMB against the U.S. dollar may last and when and how the relationship between the RMB and the U.S. dollar may change again.

All of our revenue and substantially all of our costs are denominated in Renminbi. We are a holding company and we rely on dividends paid by our operating subsidiaries in China for our cash needs. Any significant revaluation of Renminbi may materially and adversely affect our results of operations and financial position reported in Renminbi when translated into U.S. dollars, and the value of, and any dividends payable on, the ADSs in U.S. dollars. To the extent that we need to convert U.S. dollars we receive from this offering into

43

Renminbi for our operations, appreciation of the Renminbi against the U.S. dollar would have an adverse effect on the Renminbi amount we would receive. Conversely, if we decide to convert our Renminbi into U.S. dollars for the purpose of making payments for dividends on our ordinary shares or ADSs or for other business purposes, appreciation of the U.S. dollar against the Renminbi would have a negative effect on the U.S. dollar amount.

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

The PRC government imposes controls on the convertibility of the Renminbi into foreign currencies and, in certain cases, the remittance of currency out of China. We receive substantially all of our revenues in Renminbi. Under our current corporate structure, our Cayman Islands holding company primarily relies on dividend payments from our PRC subsidiaries to fund any cash and financing requirements we may have. Under existing PRC foreign exchange regulations, payments of current account items, including profit distributions, interest payments and trade and service-related foreign exchange transactions, can be made in foreign currencies without prior approval of SAFE by complying with certain procedural requirements. Specifically, under the existing exchange restrictions, without prior approval of SAFE, cash generated from the operations of our PRC subsidiaries in China may be used to pay dividends to our company. However, approval from or registration with appropriate government authorities is required where Renminbi is to be converted into foreign currency and remitted out of China to pay capital expenses such as the repayment of loans denominated in foreign currencies. As a result, we need to obtain SAFE approval to use cash generated from the operations of our PRC subsidiaries and VIE to pay off their respective debt in a currency other than Renminbi owed to entities outside China, or to make other capital expenditure payments outside China in a currency other than Renminbi. The PRC government may at its discretion restrict access to foreign currencies for current account transactions in the future. If the foreign exchange control system prevents us from obtaining sufficient foreign currencies to satisfy our foreign currency demands, we may not be able to pay dividends in foreign currencies to our shareholders, including holders of our ADSs.

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

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

44

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

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

Under SAFE Circular 37, PRC residents who make, or have prior to the implementation of SAFE Circular 37 made, direct or indirect investments in offshore special purpose vehicles, or SPVs, will be required to register such investments with SAFE or its local branches. In addition, any PRC resident who is a direct or indirect shareholder of an SPV is required to update its filed registration with the local branch of SAFE with respect to that SPV, to reflect any material change. Moreover, any subsidiary of such SPV in China is required to urge the PRC resident shareholders to update their registration with the local branch of SAFE. If any PRC shareholder of such SPV fails to make the required registration or to update the previously filed registration, the subsidiary of such SPV in China may be prohibited from distributing its profits or the proceeds from any capital reduction, share transfer or liquidation to the SPV, and the SPV may also be prohibited from making additional capital contributions into its subsidiary in China. On February 13, 2015, the SAFE promulgated a Notice on Further Simplifying and Improving Foreign Exchange Administration Policy on Direct Investment, or SAFE Notice 13, which became effective on June 1, 2015. Under SAFE Notice 13, applications for foreign exchange registration of inbound foreign direct investments and outbound overseas direct investments, including those required under SAFE Circular 37, will be filed with qualified banks instead of SAFE. The qualified banks will directly examine the applications and accept registrations under the supervision of SAFE.

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

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

45

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

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

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 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 met: (i) the primary location of the day-to-day operational management is in the PRC; (ii) decisions relating to the enterprise’s financial and human resource matters are made or are subject to approval by organizations or personnel in the PRC; (iii) the enterprise’s primary assets, accounting books and records, company seals, and board and shareholder resolutions are located or maintained in the PRC; and (iv) at least 50% of voting board members or senior executives habitually reside in the PRC.

We believe our company is not a PRC resident enterprise for PRC tax purposes. However, the tax resident status of an enterprise is subject to determination by the PRC tax authorities and uncertainties remain with respect to the interpretation of the term “de facto management body.” If the PRC tax authorities determine that our company is a PRC resident enterprise for enterprise income tax purposes, we will be subject to PRC enterprise income on our worldwide income at the rate of 25%. Furthermore, we 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, non-resident enterprise shareholders (including our ADS holders) may be subject to PRC tax on gains realized on the sale or other disposition of ADSs or ordinary shares, if such income

46

is treated as sourced from within the PRC. Furthermore, if we are deemed a PRC resident enterprise, dividends paid to our non-PRC individual shareholders (including our ADS holders) and any gain realized on the transfer of ADSs or ordinary shares by such shareholders may be subject to PRC tax at a rate of 20% (which, in the case of dividends, may be withheld at source by us). These rates may be reduced by an applicable tax treaty, but it is unclear whether non-PRC shareholders of our company would be able to claim the benefits of any tax treaties between their country of tax residence and the PRC in the event that we are treated as a PRC resident enterprise. Any such tax may reduce the returns on your investment in the ADSs or ordinary shares.

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

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

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

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

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

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

Our independent registered public accounting firm that issues the audit report included in this prospectus, as an auditor of companies that are traded publicly in the United States and a firm registered with the Public Company Accounting Oversight Board, or the PCAOB, is required by the laws of the United States to undergo

47

regular inspections by the PCAOB to assess its compliance with the laws of the United States and professional standards. Since our auditors are located in China, a jurisdiction where the PCAOB is currently unable to conduct inspections without the approval of the Chinese authorities, our auditors are not currently inspected by the PCAOB.

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

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

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

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

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

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 to not be in compliance with the requirements of the Exchange Act, including possible delisting. Moreover, any negative

48

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 common stock 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 not to be in compliance with the requirements of the Exchange Act. Such a determination could ultimately lead to the delisting of our ADSs 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.

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

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

Risks Related to the ADSs and This Offering

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

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

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

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

49

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

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

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 ordinary shares on a per ADS basis. As a result, you will experience immediate and substantial dilution of approximately US$             per ADS. See “Dilution” for a more complete description of how the value of your investment in our ADSs will be diluted upon the completion of this offering.

If securities or industry analysts do not 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.

The sale or availability for sale of substantial amounts of ADSs could adversely affect their market price.

Sales of substantial amounts of the ADSs in the public market after the completion of this offering, or the perception that these sales could occur, could adversely affect the market price of the ADSs and could materially impair our ability to raise capital through equity offerings in the future. The ADSs sold in this offering will be freely tradable without restriction or further registration under the Securities Act, and shares held by our existing shareholders may also be sold in the public market in the future subject to the restrictions in Rule 144 and Rule 701 under the Securities Act and the applicable lockup agreements. There will be              ADSs (representing              Class A ordinary shares) outstanding immediately after this offering, or              ADSs (representing              Class A ordinary shares) if the underwriters exercise their over-allotment option in full. In connection with this offering, we[, our directors, executive officers and existing shareholders] have agreed, subject to certain exceptions, not to sell any ordinary shares or ADSs for 180 days after the date of this prospectus without the prior written consent of the representatives of the underwriters. However, the underwriters

50

may release these securities from these restrictions at any time, subject to applicable regulations of the Financial Industry Regulatory Authority, Inc. We cannot predict what effect, if any, market sales of securities held by our significant shareholders or any other shareholder or the availability of these securities for future sale will have on the market price of the ADSs. See “Underwriting” and “Shares Eligible for Future Sale” for a more detailed description of the restrictions on selling our securities after this offering.

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

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

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

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

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

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

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 flow, 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 the ADSs will likely depend entirely upon any future

51

price appreciation of the ADSs. There is no guarantee that the 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 the ADSs.

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

The M&A Rules purport to require offshore special purpose vehicles that are controlled by PRC companies or individuals and that have been formed for the purpose of seeking a public listing on an overseas stock exchange through acquisitions of PRC domestic companies or assets to obtain CSRC approval prior to publicly listing their securities on an overseas stock exchange. In September 2006, the CSRC published a notice on its official website specifying documents and materials required to be submitted to it by a special purpose vehicle seeking CSRC approval of its overseas listings. The interpretation and application of the regulations remain unclear. If CSRC approval is required, it is uncertain whether it would be possible for us to obtain the approval, and any failure to obtain or delay in obtaining CSRC approval for this offering would subject us to sanctions imposed by the CSRC and other PRC regulatory agencies.

Tian Yuan Law Firm, 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 because (i) we established the WFOE by means of direct investment and not through a merger or acquisition of the equity or assets of a “PRC domestic company” as such term is defined under the M&A Rules; and (ii) no provision in the M&A Rules classifies the contractual arrangements under the VIE Agreements as a type of acquisition transaction falling under the M&A Rules.

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

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

We are an exempted company incorporated under the laws of the Cayman Islands. Our corporate affairs are governed by our memorandum and articles of association, the Companies Law (2016 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

52

Cayman Islands is derived in part from comparatively limited judicial precedent in the Cayman Islands as well as from the common law of England, the decisions of whose courts are of persuasive authority, but are not binding, on a court in the Cayman Islands. The rights of our shareholders and the fiduciary duties of our directors under Cayman Islands law are not as clearly established as they would be under statutes or judicial precedent in some jurisdictions in the United States. In particular, the Cayman Islands have a less developed body of securities laws than the United States. Some U.S. states, such as Delaware, have more fully developed and judicially interpreted bodies of corporate law than the Cayman Islands. In addition, Cayman Islands companies may not have 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 articles of association that will become effective immediately prior to completion of this offering to determine whether or not, and under what conditions, our corporate records may be inspected by our shareholders, but are not obliged to make them available to our shareholders. This may make it more difficult for you to obtain the information needed to establish any facts necessary for a shareholder motion or to solicit proxies from other shareholders in connection with a proxy contest.

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

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

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

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 direct the voting of your Class A ordinary shares underlying your ADSs.

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

53

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

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

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

Mr. Peng Ou, our founder and chairman of our Board of Directors, Mr. Tongbo Liu, our chief executive officer and director, and certain of our senior management and employees will collectively beneficially own all of our issued and outstanding Class C ordinary shares immediately upon the completion of this offering. These Class C ordinary shares will constitute approximately         % of our total issued and outstanding share capital and         % of the aggregate voting power of our total issued and outstanding share capital immediately upon the completion of this offering, assuming the underwriters do not exercise their over-allotment option, and the issuance of sale of Class A ordinary shares in connection with concurrent private placements by Orchid Asia and New Oriental. In addition, upon the completion of this offering, up to 120,394 ordinary shares (constituting approximately         % of our total issued and outstanding share capital and         % of the aggregate voting power of our total issued and outstanding share capital immediately upon the completion of this offering, assuming the underwriters do not exercise their over-allotment options, and the issuance of sale of Class A ordinary shares in connection with concurrent private placements by Orchid Asia and New Oriental) reserved and issuable upon the exercise of options granted pursuant to our equity incentive plan adopted in October 2017 shall be, upon issuance of such ordinary shares, designated as Class C ordinary shares, the voting power of which will be held by certain of our senior employees. Immediately upon the completion of this offering, PV PLUTO LIMITED, an entity wholly owned and controlled by Primavera Capital Fund, will beneficially own all of our issued and outstanding Class B ordinary shares, which will constitute approximately         % of our total issued and outstanding share capital and         % of the aggregate voting power of our total issued and outstanding share capital immediately after the completion of this offering, assuming the underwriters do not exercise their over-allotment option, and the issuance of sale of Class A ordinary shares in connection with concurrent private placements by Orchid Asia and New Oriental.

54

As a result of this triple-class share structure and the concentration of ownership, Mr. Peng Ou, Mr. Tongbo Liu and certain of our senior management and employees will have significant influence over our business, including decisions regarding mergers, consolidations, liquidations and the sale of all or substantially all of our assets, election of directors and other significant corporate actions. 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.

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

We may, from time to time, distribute rights to our shareholders, including rights to acquire securities. Under the deposit agreement, the depositary will not distribute rights to holders of 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 be subject to limitations on the 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 it expedient in connection with the performance of its duties. The depositary may close its books in emergencies, and on weekends and public holidays. The depositary may refuse to deliver, transfer or register transfers of our 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.

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.

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:

55

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.

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 New York Stock Exchange corporate governance listing standards. These practices may afford less protection to shareholders than they would enjoy if we complied fully with the New York Stock Exchange corporate governance listing standards.

As a Cayman Islands company listed on the New York Stock Exchange, we are subject to New York Stock Exchange corporate governance listing standards. However, New York Stock Exchange 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 New York Stock Exchange corporate governance listing standards. We intend to follow Cayman Islands corporate governance practices in lieu of the corporate governance requirements of the New York Stock Exchange that listed companies must have: (i) a majority of independent directors; (ii) a nominating/corporate governance committee composed entirely of independent directors; and (iii) a compensation committee composed entirely of independent directors. To the extent we choose to follow home country practice in the future, our shareholders may be afforded less protection than they otherwise would enjoy under New York Stock Exchange corporate governance listing standards applicable to U.S. domestic issuers.

There can be no assurance that we will not be a passive foreign investment company, or PFIC, for any taxable year, which could result in adverse U.S. federal income tax consequences to U.S. investors in the ADSs or our ordinary shares.

In general, a non-U.S. corporation is a PFIC for U.S. federal income tax purposes for any taxable year in which (i) 75% or more of its gross income consists of passive income or (ii) 50% or more of the average quarterly value of its assets consists of assets that produce, or are held for the production of, passive income. For purposes of the above calculations, a non-U.S. corporation that owns at least 25% by value of the shares of another corporation is treated as if it held its proportionate share of the assets of the other corporation and received directly its proportionate share of the income of the other corporation. Cash is a passive asset for these purposes. Based on the expected composition of our income and assets and the value of our assets, including goodwill, which is based on the expected price of our ADSs in this offering, we do not expect to be a PFIC for our current taxable year. However, it is not entirely clear how the contractual arrangements between our wholly-owned PRC subsidiary Wuhan Zhibo, our consolidated affiliated entity and the shareholders of our consolidated affiliated entity will be treated for purposes of the PFIC rules. Because the treatment of the contractual arrangements is not entirely clear, because we will hold a substantial amount of cash following this offering, and because our PFIC status for any taxable year can be determined only after the end of such year and will depend on the composition of our income and assets and the value of our assets from time to time (which may be determined, in part, by reference to the market price of the ADSs or ordinary shares, which could be volatile), there can be no assurance that we will not be a PFIC for our current or any future taxable year. If we were a PFIC for any taxable year during which a U.S. investor holds ADSs or ordinary shares, certain adverse U.S. federal income tax consequences could apply to such U.S. investor. See “Taxation—Material U.S. Federal Income Tax Considerations—Passive Foreign Investment Company Rules.”

LETTER FROM OUR FOUNDER AND CHAIRMAN

At Sunlands, we are proud of what we do and what we have accomplished. Started in 2003 as an offline, classroom-based education company, we have now become China’s largest online post-secondary and professional education service provider, powered by China’s internet boom that has driven our operating results and established the foundation for our future growth.

I am particularly confident about our business due to the “flywheel effect” we enjoy—our investments in people, technology and education research and development generate strong organic momentum and propel us toward continuous growth and innovation, creating a virtuous cycle. As a public company, we will continue to invest prudently in our business to maintain our leading position and ensure our future success.

What inspires me every day is seeing our education services empower and enrich lives of our students.

Make high-quality education available to everyone

Everyone, no matter their station in life, should have access to high-quality education. Our online education platform makes education more accessible, removing the obstacles of traditional offline model that have made education unattainable for a vast number of people. We aim to meet China’s expanding education needs and previously unserved student population by continuing to offer high-quality online courses and building a vast library of educational resources that can be easily accessed through the internet.

Provide education that elevates and enriches lives

Today’s higher education has been influenced by two distinct models—Newman’s theory of a liberal education and Humboldt’s model of specialized education. While specialized professionals are necessary, we need more generalists, especially as many jobs become outdated faster than we realize as our technology continues to transform our society. I hope to instill the essence of a liberal education in our course offerings, through our own innovations and business partnerships. This will have a positive and lasting impact on our students’ lives, not only by helping them obtain diplomas and degrees that can help them achieve short-term career goals, but also by elevating and enriching their lives by teaching them to think critically and solve complex problems.

Nurture and spread new ideas

The core purpose of education is to spur innovation and generate ideas. I want to encourage and support our future faculty to spread knowledge and ideas, to research and innovate, and to promote science and humanities. Strengthening our leadership and fulfilling the core purpose of education requires us to motivate the smartest among us to explore and expand the boundaries of what we know.

There is a saying that the two most important days in one’s life is the day you are born and the day you discover your mission. The challenges and endless possibilities of fulfilling our mission is what excites me about our future. As we continue to create value for our students, employees and shareholders, we will strive to make the world better through the combined powers of education and technology.

Peng Ou

USE OF PROCEEDS

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

We plan to use the net proceeds of this offering primarily for the following purposes: (i) approximately US$             million for our course and educational content development, (ii) approximately US$             million for our research and development relating to our IT systems, (iii) approximately US$             million for our marketing and branding activities, (iv) approximately US$             million for potential selective investment and acquisition opportunities, and (v) approximately US$             million for general corporate purpose. If an unforeseen event occurs or business conditions change, we may use the proceeds of this offering differently than as described in this prospectus. In utilizing the proceeds from this offering, we are permitted under PRC laws and regulations to provide funding to our PRC subsidiaries only through loans or capital contributions, and to our consolidated VIE only through loans, and only if we satisfy the applicable government registration and approval requirements. We cannot assure you that we will be able to meet these requirements on a timely basis, if at all. See “Risk Factors—Risks Related to Doing Business in China—PRC regulation of loans to and direct investment in PRC entities by offshore holding companies and governmental control of currency conversion may delay us from using the proceeds of this offering to make loans or additional capital contributions to our PRC subsidiary, which could materially and adversely affect our liquidity and our ability to fund and expand our business.”

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

59

DIVIDEND POLICY

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

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

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

CAPITALIZATION

The following table sets forth our capitalization as of December 31, 2017:

You should read this table together with our consolidated financial statements and the related notes included elsewhere in this prospectus and the information under “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

Notes:

62

DILUTION

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

Our net tangible book value as of December 31, 2017 was approximately US$             per ordinary share and US$             per ADS. Net tangible book value per ordinary share represents the amount of total tangible assets, minus the amount of total liabilities, divided by the total number of ordinary shares outstanding. Dilution is determined by subtracting net tangible book value per ordinary share from the public offering price per Class A ordinary share.

Without taking into account any other changes in such net tangible book value after December 31, 2017, other than to give effect to (i) the conversion of all of our preferred shares into ordinary shares on a one-to-one basis, which will occur automatically immediately upon the completion of this offering and (ii) our issuance and sale of ADSs, representing             Class A ordinary shares, offered in this offering and              Class A ordinary shares issued and sold in connection with concurrent private placements to Orchid Asia and New Oriental at an initial public offering price of US$             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 December 31, 2017 would have been approximately US$             million, or US$             per ordinary share and US$             per ADS, to existing shareholders and an immediate dilution in net tangible book value of US$             per ordinary share, or US$             per ADS, to purchasers of ADSs in this offering.

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

The pro forma information discussed above is illustrative only.

The following table summarizes, on a pro forma basis as of December 31, 2017, the differences between the existing shareholders and the new investors with respect to the number of ordinary shares purchased from us in this offering, the total consideration paid and the average price per ordinary share paid at the initial public offering price of US$             per ADS before deducting estimated underwriting discounts and commissions and estimated offering expenses. The total number of ordinary shares does not include ordinary shares underlying the ADSs issuable upon the exercise of the over-allotment option granted to the underwriters.

63

The discussion and tables above also assume no exercise of any stock options outstanding as of the date of this prospectus. As of the date of this prospectus, there are 60,826 ordinary shares issuable upon exercise of outstanding stock options with an exercise price of US$84.75 per ordinary share, and there are a total of 120,394 ordinary shares available for future issuance upon the exercise of grants under the 2017 Plan. To the extent that any of these options are exercised, there will be further dilution to new investors.

64

EXCHANGE RATE INFORMATION

Our reporting currency is the Renminbi because our business is mainly conducted in China and all of our revenues are denominated in Renminbi. This prospectus contains translations of Renminbi amounts into U.S. dollars at specific rates solely for the convenience of the reader. The conversion of Renminbi into U.S. dollars in this prospectus is based on the rate certified for customs purposes by the Federal Reserve Bank of New York. Unless otherwise noted, all translations from Renminbi to U.S. dollars and from U.S. dollars to Renminbi in this prospectus are made at RMB6.5063 to US$1.00, the exchange rate set forth in the H.10 statistical release of the Federal Reserve Board on December 29, 2017. We make no representation that any Renminbi or U.S. dollar amounts could have been, or could be, converted into U.S. dollars or Renminbi, as the case may be, at any particular rate, the rates stated below, or at all. The PRC government imposes control over its foreign currency reserves in part through direct regulation of the conversion of Renminbi into foreign exchange and through restrictions on foreign trade. On March 2, 2018, the rate was RMB6.3428 to US$1.00.

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