**ITEM 3. KEY INFORMATION**

**Our Holding Company Structure**

Sunlands Technology Group is a Cayman Islands holding company that does not conduct operations by itself. The Group's operations in China are conducted through our PRC subsidiaries and the consolidated variable interest entities, or the VIEs. However, we and our direct and indirect subsidiaries do not, and it is virtually impossible for them to, have any equity interests in the VIEs in practice as current PRC laws and regulations restrict foreign investment in companies that engage in value-added telecommunication services. As a result, we depend on certain contractual arrangements with the VIEs to operate a significant portion of the Group's business. This structure allows us to be considered the primary beneficiary of the VIEs for accounting purposes, which serves as the basis for consolidating the VIEs' operating results in the Group's financial statements under U.S. GAAP. The VIEs are owned by certain nominee shareholders, not us. Most of the nominee shareholders of the VIEs are also beneficial owners of our company. Investors in the ADSs are purchasing equity securities of a Cayman Islands holding company rather than equity securities issued by our subsidiaries and the VIEs. Investors who are non-PRC residents may never directly hold equity interests in the VIEs under current PRC laws and regulations. As used in this annual report, "we," "us," "our company" or "our" refers to Sunlands Technology Group and its subsidiaries. "Variable interest entities" or "VIEs" refers to Wuhan Xiaoyan Technology Co., Ltd., or Wuhan Xiaoyan, and Beijing Lingding Management Consulting Co., Ltd., or Beijing Lingding. The VIEs primarily conduct operations in China. The VIEs are consolidated for accounting purposes but are not entities in which we own equity.

The following chart illustrates the Group's organizational structure, including our significant subsidiaries as "significant" is defined under Section 1-02 of Regulation S-X under the Securities Act and certain other subsidiaries and certain VIE as of the date of this annual report.

———— Equity interest

------------ Contractual arrangements

------

The Group's corporate structure involves unique risks to investors in the ADSs. In 2023, 2024 and 2025, the amount of revenues generated by the VIEs accounted for 63.4%, 83.9% and 48.5%, respectively, of the Group's total net revenues. As of December 31, 2024 and 2025, the total assets of the VIEs, excluding amounts due from other consolidated entities in the Group, equaled to 21.4% and 3.3% of the Group's consolidated total assets as of the same dates, respectively. As of the date of this annual report, to the best knowledge of our directors and management, the VIE agreements have not been tested in a court of law in the PRC. If the PRC government deems that our contractual arrangements with the VIEs do not comply with PRC regulatory restrictions on foreign investment in the relevant industries, or if these regulations or the interpretation of existing regulations change in the future, we could be subject to material penalties or be forced to relinquish our contractual interests in those operations or otherwise significantly change the Group's corporate structure. We and our investors face significant uncertainty about potential future actions by the PRC government that could affect the legality and enforceability of the contractual arrangements with the VIEs and, consequently, significantly affect our ability to consolidate the financial results of the VIEs and the financial performance of the Group as a whole. The ADSs may decline in value or become worthless if we are unable to effectively enforce our contractual control rights over the assets and operations of the VIEs that conduct a significant portion of the Group's business in China. See "Item 3. Key Information—3.D. Risk Factors—Risks Related to Our Corporate Structure" for detailed discussion.

**Contractual Arrangements and Corporate Structure**

We are a Cayman Islands exempted company and currently conduct substantially all business operations in the PRC through our subsidiaries incorporated in the PRC and the contractual arrangements among our PRC subsidiaries and the VIEs. It is the VIEs that hold key operating licenses, provide services to customers, and enter into contracts with suppliers. We operate the Group's business this way because PRC laws and regulations restrict foreign investment in companies that engage in value-added telecommunication services. These contractual arrangements entered into with the VIEs allow us to (i) direct the activities of the VIEs that most significantly impact the VIEs' economic performance, (ii) receive substantially all of the economic benefits of the VIEs, and (iii) have an exclusive option to purchase all or part of the equity interests in the VIEs when and to the extent permitted by PRC law. The VIE structure is used to provide investors with exposure to foreign investment in China-based companies where PRC law restricts direct foreign investment in such operating companies in the PRC. These contractual arrangements include the operating agreements, equity pledge agreements, exclusive purchase option agreements, shareholder voting right trust agreements, loan agreements, and cooperation agreements, as the case may be. As a result of these contractual arrangements, we are considered the primary beneficiary of the VIEs for accounting purposes and are able to consolidate their operating results in the Group's financial statements under U.S. GAAP.

It is important to note that investors in the ADSs are purchasing equity securities of a Cayman Islands holding company rather than equity securities issued by our subsidiaries and the VIEs. More specifically, investors in the ADSs or our ordinary shares would not be holding any ownership interest, directly or indirectly, in the VIEs under current PRC laws and regulations as investors would only have the contractual relationship with the operating entities in the PRC. Neither such investors nor the holding company itself have an equity ownership in, direct investment in, or control of, through such ownership or investment, the VIEs. Investors who are non-PRC residents may never directly hold equity interests in the VIEs under current PRC laws and regulations. We do not have any equity interests in the VIEs who are owned by certain nominee shareholders. Any of such nominee shareholders could breach their contractual arrangements with us by, among other things, failing to conduct their operations in an acceptable manner or taking other actions that are detrimental to our interests. In the event that the shareholders of the VIEs breach the terms of these contractual arrangements and voluntarily liquidate the VIEs, or the VIEs declare bankruptcy and all or part of their 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 business operations or otherwise benefit from the assets held by the VIEs and their shareholders, which could have a material adverse effect on the Group's business, financial condition and results of operations. As a result, the contractual arrangements may be less effective than direct ownership, and we could face heightened challenges, risks and costs in enforcing these contractual arrangements due to legal uncertainties and jurisdictional limits, because there are uncertainties regarding the interpretation and application of current and future PRC laws, regulations, and rules relating to the legality and enforceability of these contractual arrangements. If the PRC government finds such agreements to be illegal, we could be subject to severe penalties or be forced to relinquish our interests in the VIEs.

**Contractual Arrangements with Consolidated VIEs and Their Shareholders** 

Currently, the Group's online education service business in China is operated partially through the VIEs and their subsidiaries due to PRC legal restrictions on foreign ownership in value-added telecommunication services and other internet related business, and we are considered the primary beneficiary of each of the VIEs for accounting purposes through a series of contractual arrangements.

In August 2017 and March 2023, Wuhan Studyvip Online Education Co. Limited, or Wuhan Zhibo, a wholly-owned subsidiary of us, entered into a series of contractual arrangements with Beijing Yuanchilaxiang Education Technology Co., Ltd (formerly known as "Beijing Shangde Online Education Technology Co., Ltd."), or Beijing Sunlands, as well as its shareholders and, where applicable, its operating subsidiaries pursuant to which we became the primary beneficiary of

------

Beijing Sunlands for accounting purposes. In December 2025, Wuhan Zhibo terminated those contractual arrangements with Beijing Sunlands and the other relevant parties, and Beijing Sunlands became a wholly-owned subsidiary of Wuhan Zhibo.

Our wholly-owned subsidiaries have entered into a series of contractual arrangements with the VIEs, their shareholders and operating subsidiaries, where applicable, respectively. Through such contractual agreements, our wholly-owned subsidiaries are able to (i) direct the activities of the VIEs that most significantly impact the VIEs' economic performance, (ii) receive substantially all of the economic benefits of the VIEs, and (iii) have an exclusive option to purchase all or part of the equity interests in the VIEs when and to the extent permitted by PRC law. The Group is therefore considered the primary beneficiaries of the VIEs and their subsidiaries for accounting purposes and are able to consolidate their operating results in the Group's financial statements under U.S. GAAP.

The following sets forth the principal terms of the contractual arrangements entered into among our subsidiaries, the relevant VIEs and their respective shareholders and, where applicable, subsidiaries.

***Exclusive Technical Consultation and Service Agreement.*** Under the exclusive technical consultation and service agreement among Wuhan Zhibo and the VIEs, Wuhan Zhibo has the exclusive right to provide, among other things, technical consultation and services to the VIEs and their subsidiaries, and the VIEs and their subsidiaries agree to accept all the consultation and services provided by Wuhan Zhibo. Without Wuhan Zhibo's prior written consent, the VIEs and their subsidiaries are prohibited from engaging any third party to provide any services contemplated by this agreement. In addition, Wuhan Zhibo has exclusive and proprietary ownership, rights and interests in any and all intellectual properties arising out of or created during the performance of this agreement. The VIEs and their subsidiaries agree to pay a quarterly service fee to Wuhan Zhibo at an aggregate amount of a certain percentage ranging from 10% to 100% of monthly revenue of the VIEs and their subsidiaries. Unless terminated by Wuhan Zhibo, this agreement will remain effective until the dissolution of the VIEs and their subsidiaries. Without Wuhan Zhibo's prior written consent, the VIEs and their subsidiaries do not have the right to terminate this exclusive technical consultation and service agreement.

***Business Operation Agreement.*** Under the business operation agreement, each of the VIEs, their subsidiaries and their shareholders confirmed and agreed that, without Wuhan Zhibo's prior written consent, they shall not make any transaction that has a material adverse effect on the assets, business, personnel, obligations, rights or operations of the VIEs and their subsidiaries, including but not limited to sale or purchase of any assets or rights exceeding RMB50,000, incurrence of any encumbrance on any of their assets, including intellectual property rights, in favor of a third party, amendment of their articles of association or business scope, or change of their normal operation procedures. The VIEs, their subsidiaries and their shareholders shall accept and execute opinions and instructions of Wuhan Zhibo in connection with the employee engagement and dismissal, daily operations and financial management systems. The shareholders of the VIEs shall elect or appoint the candidates recommended by Wuhan Zhibo as the VIEs' respective directors and supervisors, and procure the appointment of the VIEs' respective chairman of the board and senior management pursuant to Wuhan Zhibo's designation. The agreement also provides that if any of the agreements among Wuhan Zhibo, the VIEs and their subsidiaries is terminated, Wuhan Zhibo is entitled to terminate all of the other agreements among itself, the VIEs and their subsidiaries. This agreement will remain binding until dissolution of the VIEs and all the subsidiaries of the VIEs.

***Equity Interest Pledge Agreement.*** Under the equity interest pledge agreement among Wuhan Zhibo, the shareholders of the VIEs and the VIEs, the shareholders of the VIEs pledged all of their respective equity interests in the VIEs to Wuhan Zhibo as security for performance of the obligations of the VIEs and their shareholders under the exclusive technical consultation and service agreement, the option agreement and the business operation agreement. The shareholders of the VIEs shall instruct respective VIEs not to distribute any dividends and shall not approve any profit distribution plan. If any of the specified events of default occurs, Wuhan Zhibo may exercise the right to enforce the pledges after giving a notice of default to the shareholders of the VIEs. Wuhan Zhibo may assign any and all of its rights and obligations under the equity interest pledge agreement to its designee(s) at any time. The equity interest pledge agreement is binding on the shareholders of the VIEs and their successors.

***Option Agreement.*** Pursuant to the option agreement among Wuhan Zhibo, the shareholders of the VIEs and the VIEs, each of the shareholders irrevocably granted Wuhan Zhibo a right to purchase, or designate a third party to purchase, equity interests in the VIEs then held by each shareholder at once or at multiple times at any time in part or in whole at Wuhan Zhibo's sole and absolute discretion to the extent permitted by PRC law. The shareholders of the VIEs shall promptly surrender all considerations they received from the exercise of the options to Wuhan Zhibo or the designated third party free of charge. Without Wuhan Zhibo's prior written consent, the shareholders of the VIEs shall not, individually or collectively, make or procure the VIEs to make in any transaction or conduct that has a material adverse effect on the assets, liabilities, operations, equity and other legal rights of the VIEs. Without Wuhan Zhibo's prior written consent, the VIEs shall not enter into any contract exceeding RMB50,000, except the contracts in the ordinary course of the business. The VIEs shall not be dissolved or liquidated without prior written consent by Wuhan Zhibo. The shareholders of the VIEs waive their rights of pre-emption in regard to the transfer of equity interest by any other shareholder of the VIEs to Wuhan Zhibo as instructed.

***Powers of Attorney.*** Pursuant to the powers of attorney executed by the shareholders of the VIEs, the shareholders of the VIEs each irrevocably authorized Wuhan Zhibo to act on their respective behalf as exclusive agent and attorney with

------

respect to all rights of shareholders concerning all equity interests held by each of them in the VIEs, including but not limited to propose to convene shareholder meetings, accept any notice with respect to the convening and proceeding of the shareholder meeting, attend shareholder meetings, sign the shareholders resolutions on their behalf, exercise all the shareholder's rights according to laws and regulations and the VIEs' articles of association (including but not limited to voting rights and the sale transfer, pledge or dispose of all equity interests held in part or in whole) and designate and appoint on their respective behalf the president, directors, supervisors, chief executive officer, chief financial officer and other senior management members of the VIEs.

In addition, in case where shareholders have spouses, the spouses of the shareholders of the VIEs also executed spousal consent letters to confirm that the equity interests of the VIEs are the own property of the shareholders and shall not constitute the jointly possessed property of the couples, and irrevocably waived any potential right or interest that may be granted by operation of applicable law in connection with the equity interests of the VIEs held by the shareholders.

As a result of the contractual arrangements above, our wholly-owned subsidiaries bear the economic risks and receive the economic benefits of the VIEs, hold the power in directing the significant activities of the VIEs, and are the primary beneficiary of the VIEs for accounting purposes. Therefore, we have consolidated the financial results of the VIEs and their subsidiaries in the Group's consolidated financial statements.

In the opinion of Tian Yuan Law Firm, our PRC legal counsel, (i) the contractual arrangements among our wholly-owned PRC subsidiaries, the VIEs, the VIEs' respective shareholders and the VIEs' respective subsidiaries are valid, binding and enforceable under the PRC laws and regulations currently in effect; and (ii) the ownership structures of the VIEs and our WFOEs under the contractual arrangements aforesaid currently are not in violation of applicable PRC laws and regulations currently in effect.

However, these contractual arrangements may not be as effective in providing control as direct ownership. There are uncertainties regarding the interpretation and application of current or future PRC laws and regulations. Accordingly, Chinese regulatory authorities may take a view that is contrary to the opinion of our PRC legal counsel. For a description of the risks related to our corporate structure, please see "Item 3. Key Information—3.D. Risk Factors—Risks Related to Our Corporate Structure."

**Licenses and Approvals**

As advised by Tian Yuan Law Firm, our PRC legal counsel, except for the filings associated with our mobile apps under Notice on the Filing of Mobile Internet Apps, we believe our PRC subsidiaries and the VIEs have obtained all licenses and approvals explicitly required and necessary for the Group's operations in China; however, a number of the Group's operating entities currently do not hold certain licenses and approvals or complete certain regulatory filings which are not explicitly required under the current PRC laws and regulations to date for their business operations but may be required in the future if the PRC regulatory authorities change their views as to the interpretation and implementation of such laws and regulations. To the extent such licenses, approvals or filings are required, the Group's failure to secure such licenses, permits or filings in a timely manner, or at all, could have a material adverse impact on its business operations. These licenses, approvals or filings include the filings associated with our mobile apps under the Opinions on Guiding and Regulating the Orderly and Healthy Development of Educational Mobile Apps, the Private School Operating Permit, the License for Online Transmission of Audio-Visual Programs, the Internet Publishing License, the Value-Added Telecommunications Business Operating License, the License for the Production and Operation of Radio and Television Program, the Internet News Information License, the Publication License, and the filing as a live-streaming platform. For details, see "Item 3. Key Information—3.D. Risk Factors—Risks Related to the Group's Business—The Group faces risks associated with the lack of a private school operating permit for 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," "Item 3. Key Information—3.D. Risk Factors—Risks Related to the Group's Business—The Group faces regulatory risks and uncertainties with respect to the licensing requirement for the online transmission of internet audio-visual programs," "Item 3. Key Information—3.D. Risk Factors—Risks Related to the Group's Business—The failure to obtain and maintain other approvals, licenses, permits or filings applicable to the Group's business could have a material adverse impact on the Group's business, financial conditions and results of operations," and "Item 3. Key Information—3.D. Risk Factors—Risks Related to the Group's Business—The Group is subject to a variety of laws and other obligations regarding data protection, and any failure to comply with applicable laws and obligations could have a material adverse effect on the Group's business, financial condition and results of operations."

The following table sets forth a list of licenses and approvals, subject to further renewal, that our PRC subsidiaries and the VIEs are explicitly required to obtain and necessary to carry out the Group's operations in China as of the date of this annual report and none of such licenses and approvals obtained had been denied or rescinded.

Given the uncertainties of interpretation and implementation of relevant laws and regulations and the enforcement practice by relevant government authorities, the Group may be required to obtain additional licenses, permits, filings, registrations or approvals for business operations in the future. If the Group is found to be in violation of any existing or future PRC laws or regulations, or fails to obtain or maintain any of the required licenses, permits, filings, registrations or approvals, the relevant PRC regulatory authorities would have broad discretion to take action in dealing with such violations or failures. In addition, if the Group had inadvertently concluded that such licenses, approvals, permits, registrations or filings were not required, or if applicable laws, regulations or interpretations change in a way that requires the Group to obtain such licenses, approval, permits, registrations or filings in the future, the Group may be unable to obtain such necessary licenses, approvals, permits, registrations or filings in a timely manner, or at all, and such licenses, approvals, permits, registrations or filings may be rescinded even if obtained. Any such circumstance may subject the Group to fines and other regulatory, civil or criminal liabilities, and the Group may be ordered by the competent government authorities to suspend relevant operations, which will materially and adversely affect the Group's business operation. For

------

risks relating to licenses and approvals required for business operations in China, see "Item 3. Key Information—3.D. Risk Factors—Risks Related to the Group's Business."

As advised by our PRC legal counsel, under the currently effective PRC laws and regulations, except as disclosed in "Item 3. Key Information—3.D. Risk Factors—Risks Related to the Group's Business—The Group is subject to a variety of laws and other obligations regarding data protection, and any failure to comply with applicable laws and obligations could have a material adverse effect on the Group's business, financial condition and results of operations," Sunlands Technology Group, our subsidiaries and the VIEs are not subject to the permission requirements from the CAC with respect to business operations, based on the fact that, as of the date of this annual report, none of Sunlands Technology Group, our subsidiaries and the VIEs has been identified by any PRC governmental authority as an "critical information infrastructure operator" that will be subject to the CAC's cybersecurity review requirements. However, there remain uncertainties on the interpretation and implementations of the Cybersecurity Review Measures and other laws and regulations regarding cybersecurity and data protection. If the CAC or other regulatory agencies subsequently require that their approvals be obtained for the Group's respective data processing activities, the Group may be unable to obtain such approvals in a timely manner, or at all, and such approvals may be rescinded even if obtained. For details, see "Item 3. Key Information—Recent Regulatory Development—Cybersecurity Review Measures."

In addition, the PRC government has recently indicated an intent to exert more oversight over overseas securities offerings and published a series of laws and regulations to regulate such transactions. In connection with our prior overseas offerings and listing status on the New York Stock Exchange (the "NYSE"), as of the date of this annual report, we (i) have not been required to obtain any permission from or complete any filing with the CSRC, and (ii) have not been required to go through a cybersecurity review by the CAC. As advised by our PRC legal counsel, under the currently effective PRC laws and regulations, as a group that has been listed on a foreign stock exchange before the promulgation of the Revised Cybersecurity Review Measures, Sunlands Technology Group, our subsidiaries and the VIEs are not required to go through a cybersecurity review by the CAC to conduct a security offering or maintain our listing status on the NYSE, based on their consultation with competent government authorities. According to the press conference held by CSRC for the release of the Overseas Listing Trial Measures and the Notice on Administration for the Filing of Overseas Offering and Listing by Domestic Companies, as a group that has been listed on a foreign stock exchange prior to the effective date of the Overseas Listing Trial Measures, Sunlands Technology Group, our subsidiaries and the VIEs are not required to complete the filing with the CSRC to maintain our listing status on the NYSE, but we will be required to undergo the filing procedures with the CSRC for our future offerings, listing or any other capital raising activities within the applicable scope of the Overseas Listing Trial Measures. Since the Overseas Listing Trial Measures were newly promulgated, there remain significant uncertainties surrounding the interpretation, application and enforcement of such measures. We cannot assure you that we could complete the filing procedure as required with the CSRC under the Overseas Listing Trial Measures for any of our future offerings, listing or any other capital raising activities in a timely manner, or at all, and such filings may be rescinded even if completed. Any such circumstance could subject the Group to penalties, including fines, suspension of business and revocation of required licenses, significantly limit or completely hinder our ability to continue to offer securities to investors and cause the value of such securities to significantly decline or be worthless. For more detailed information, see "Item 3. Key Information—3.D. Risk Factors—Risks Related to Doing Business in China—The approval, filing or other requirements of the China Securities Regulatory Commission or other PRC government authorities may be required under PRC law in connection with our issuance of securities overseas, and if required, we cannot predict whether or for how long the Group will be able to obtain such approval or complete such filing or other requirements."

**Recent Regulatory Development**

**Cybersecurity Review Measures**

On January 4, 2022, the Cyberspace Administration of China, or the CAC, published the Revised Cybersecurity Review Measures, which became effective on February 15, 2022 and repeal the Cybersecurity Review Measures promulgated on April 13, 2020. The Revised Cybersecurity Review Measures provide that a critical information infrastructure operator purchasing network products and services, and platform operators carrying out data processing activities, which affect or may affect national security, shall apply for cybersecurity review and that a platform operator with more than one million users' personal information aiming to list abroad must apply for cybersecurity review. As the Revised Cybersecurity Review Measures is newly promulgated, it is uncertain how the measures will be interpreted or implemented and how they will affect the Group. We cannot predict the impact of the Revised Cybersecurity Review Measures, if any, at this stage, and we will closely monitor and assess any development in the rule-making process.

In anticipation of the strengthened implementation of cybersecurity laws and regulations and the continued expansion of the Group's business, the Group faces potential risks if the Group is deemed as a "critical information infrastructure operator" or "platform operator" under the PRC cybersecurity laws and regulations, and would be required to follow cybersecurity review procedures. During such review, the Group may be required to suspend providing any existing or new services to the Group's customers and/or experience other disruptions of the Group's operations, and such review could also result in negative publicity with respect to the Group and diversion of the Group's managerial and financial resources.

------

As of the date of this annual report, the Group has not been involved in any investigations or becomes subject to a cybersecurity review initiated by the CAC based on the Revised Cybersecurity Review Measures, and the Group has not received any inquiry, notice, warning, sanctions in such respect or any regulatory objections to our listing status from the CAC.

As advised by our PRC legal counsel, Tian Yuan Law Firm, under the currently effective PRC laws and regulations, except as disclosed in "Item 3. Key Information—3.D. Risk Factors—Risks Related to the Group's Business—The Group is subject to a variety of laws and other obligations regarding data protection, and any failure to comply with applicable laws and obligations could have a material adverse effect on the Group's business, financial condition and results of operations," Sunlands Technology Group, our subsidiaries and the VIEs are not covered by permission requirements from the CAC (i) to conduct a security offering or maintain our listing status on the NYSE, or (ii) to conduct business operations, on the following grounds: (i) our PRC legal counsel has consulted the competent government authorities which acknowledged that, under the currently effective PRC laws and regulations, a company that has been listed on a foreign stock exchange before the promulgation of the Revised Cybersecurity Review Measures is not required to go through a cybersecurity review by the CAC to conduct a securities offering or to maintain its listing status on the foreign stock exchange on which its securities have been listed; (ii) as of the date of this annual report, none of Sunlands Technology Group, our subsidiaries and the VIEs has been identified by any PRC governmental authority as a "critical information infrastructure operator" that will be subject to the CAC's cybersecurity review requirements. However, there remain uncertainties on the interpretation and implementations of the Revised Cybersecurity Review Measures and other laws and regulations regarding cybersecurity and data protection. If the CAC or other regulatory agencies later require that the Group obtains their approvals for our future offshore offerings or for the Group's data processing activities, the Group may be unable to obtain such approvals in a timely manner, or at all, and such approvals may be rescinded even if obtained. Any such circumstance may significantly limit or completely hinder our ability to continue to offer securities to investors, subject the Group to penalties, or cause the Group to alter the Group's business model or practices and cause the value of such securities to significantly decline or be worthless.

**Potential CSRC Filing Required for the Listing of the ADSs**

On February 17, 2023, the CSRC released the Trial Administrative Measures of Overseas Securities Offering and Listing by Domestic Companies, or the Overseas Listing Trial Measures, and five supporting guidelines, effective on March 31, 2023. Pursuant to the Overseas Listing Trial Measures, PRC domestic companies that seek to offer or list securities overseas, either in direct or indirect means, are required to report and file required documents with the CSRC. On the same day, the CSRC also held a press conference for the release of the Overseas Listing Trial Measures and issued the Notice on Administration for the Filing of Overseas Offering and Listing by Domestic Companies, which, among others, clarifies that domestic companies that have been listed on a foreign stock exchange prior to the effective date of the Overseas Listing Trial Measures are required to file with the CSRC within three working days of the completion of fundraising activities on the same overseas capital market and shall make the required filing immediately after they submit the application for their listing or offering securities in other overseas capital markets. As advised by our PRC legal counsel, Tian Yuan Law Firm, as a group that has been listed on a foreign stock exchange prior to the effective date of the Overseas Listing Trial Measures, Sunlands Technology Group, our subsidiaries and the VIEs are not required to complete the filing with the CSRC only to maintain our listing status on the NYSE. However, Sunlands Technology Group, our subsidiaries or the VIEs will be required to conduct the filing procedures with the CSRS for our future offerings, listing or any other capital raising activities within the applicable scope of the Overseas Listing Trial Measures.

As of the date of this annual report, we have not received any inquiry, notice, warning, sanctions or regulatory objection from the CSRC. However, since the Overseas Listing Trial Measures was newly promulgated, the interpretation, application and enforcement of the Overseas Listing Trial Measures remain unclear and we cannot assure you that we could be able to complete the required filing procedure in relation to our further capital raising activities in a timely manner, or at all. For more detailed information, see "Item 3. Key Information—3.D. Risk Factors—Risks Related to Doing Business in China—The approval, filing or other requirements of the China Securities Regulatory Commission or other PRC government authorities may be required under PRC law in connection with our issuance of securities overseas, and if required, we cannot predict whether or for how long the Group will be able to obtain such approval or complete such filing or other requirements."

**Transfer of Funds and Other Assets**

Under relevant PRC laws and regulations, we are permitted to remit funds to the VIEs through loans rather than capital contributions. The VIEs funded their operations primarily using cash generated from operating and financing activities. In addition, we and the VIEs may, from time to time, lend cash to each other to settle the payment obligations on each other's behalf to provide temporary working capital support. In 2023 and 2024, the net amounts of working capital support provided by the VIEs to our PRC subsidiaries were RMB602.9 million and RMB924.6 million . In 2025, the net amounts of working capital support provided by our PRC subsidiaries to the VIEs were RMB148.4 million (US$21.2 million). For more information, see "Item 3. Key Information—Condensed Consolidating Schedule," and consolidated financial statements included elsewhere in this annual report.

------

As of December 31, 2025, Sunlands Technology Group had made cumulative capital contributions of US$200.2 million to our PRC subsidiaries through an intermediate holding company. These funds have been used by our PRC subsidiaries for their operations. Our PRC subsidiaries maintained certain personnel for sales and marketing, research and development, and general and administrative functions to support the operations of the VIEs.

In 2023, 2024 and 2025, the VIEs transferred RMB26.8 million, RMB60.1 million and RMB132.6 million (US$19.0 million) of service fees to our PRC subsidiaries pursuant to the contractual arrangements, respectively. The outstanding balance of service fees owed by the VIEs to our PRC subsidiaries was nil as of each of December 31, 2023, 2024 and 2025. There were no other assets transferred between us and the VIEs in 2023, 2024 and 2025.

As advised by our PRC legal counsel, for any amounts owed by the VIEs to our PRC subsidiaries under the VIE agreements, unless otherwise required by PRC tax authorities, the Group is able to settle such amounts without limitations under the current effective PRC laws and regulations, provided that the VIEs have sufficient funds to do so and that the VIEs, in case in the form of non-enterprise institution, follow the principles of openness, fairness and impartiality, fix the price reasonably and regulate the decision-making, and do not damage the state interests, the interests of the non-enterprise institution or the rights and interests of the teachers and students when conducting such related party transaction.

Our subsidiaries are permitted to pay dividends to their shareholders, and eventually to Sunlands Technology Group, only out of their retained earnings, if any, as determined in accordance with PRC accounting standards and regulations. Such payment of dividends by entities registered in China is subject to limitations, which could result in limitations on the availability of cash to fund dividends or make distributions to shareholders of our securities. For example, our PRC subsidiaries and the VIEs are required to make appropriations to certain statutory reserve funds or may make appropriations to certain discretionary funds, which are not distributable as cash dividends except in the event of a solvent liquidation of the companies. For more details, see "Item 3. Key Information—D. Risk Factors—Risks Related to Doing Business in China—We may rely on dividends and other distributions on equity paid by our PRC and Hong Kong subsidiaries to fund any cash and financing requirements we may have, and any limitation on the ability of these subsidiaries in the PRC, including Hong Kong, to make payments to us could have a material and adverse effect on our ability to conduct the Group's business."

Sunlands Technology Group has previously declared a special cash dividend of US$1.36 per ordinary share (or US$0.68 per ADS) to holders of its ordinary shares and ADSs on June 14, 2022, which had been fully paid. 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 the Group's business. See "Item 8. Financial Information—8.A. Consolidated Statements and Other Financial Information—Dividend Policy."

On December 5, 2024, Wuhan Shangde declared a cash dividend of RMB100.0 million (US$13.7 million) to its sole shareholder, Wuhan Zhibo, which has been fully paid by December 31, 2024. On March 31, 2025, Wuhan Zhibo declared a cash dividend of RMB19.0 million (US$2.6 million) to its sole shareholder, Sunlands HK, which has been fully paid by April 10, 2025. On July 10, 2025, Wuhan Zhibo declared a cash dividend of RMB19.0 million (US$2.7 million) to its sole shareholder, Sunlands HK, which had been fully paid by July 30, 2025.

As of the date of this annual report, no transfers, dividends, or distributions between Sunlands Technology Group, our PRC subsidiaries, and the VIEs, other than those described in this annual report, have been made. As of the date of this annual report, we do not have cash management policies in place that dictate how funds are transferred between Sunlands Technology Group, our subsidiaries, the VIEs and the investors. Rather, the funds can be transferred in accordance with the applicable laws and regulations discussed in this section.

To the extent cash or assets in the business are in the PRC, including Hong Kong, or a PRC (including Hong Kong) entity, the funds or assets may not be available to fund operations or for other use outside of the PRC or Hong Kong due to interventions in or the imposition of restrictions and limitations on the ability of Sunlands Technology Group, our subsidiaries, or the VIEs by the PRC government to transfer cash or assets. There is no assurance the PRC government will not intervene in or impose restrictions on the ability of Sunlands Technology Group, our subsidiaries, or the VIEs to transfer cash or assets. See "Item 3. Key Information—3.D. Risk Factors—Risks Related to Doing Business in China—We may rely on dividends and other distributions on equity paid by our PRC and Hong Kong subsidiaries to fund any cash and financing requirements we may have, and any limitation on the ability of these subsidiaries in the PRC, including Hong Kong, to make payments to us could have a material and adverse effect on our ability to conduct the Group's business."

For the purpose of illustration, the below table reflects the hypothetical taxes that might be required to be paid within China, assuming that: (i) we have taxable earnings, and (ii) we determine to pay a dividend in the future:

Notes:

(1) The tax calculation has been simplified for the purpose of this example. The hypothetical book pre-tax earnings amount, which does not consider timing differences, is assumed to equal the taxable income in the PRC.

(2) Under the terms of the VIE agreements, sales service fees are charged by our PRC subsidiaries to the VIEs. For all the periods presented, these fees are recognized as cost of revenues of the VIEs, with a corresponding amount as service income by our PRC subsidiaries and eliminated in consolidation. For income tax purposes, our PRC subsidiaries and the VIEs file income taxes on a separate company basis. The fees paid are recognized as a tax deduction by the VIEs and as income by our PRC subsidiaries and are tax neutral.

(3) Certain of our subsidiaries qualify for a 15% preferential income tax rate in China. However, such rate is temporary in nature, and may not be available in a future period. For purposes of this hypothetical example, the table above reflects a maximum tax scenario under which the full statutory rate would be effective.

(4) Upon the instance that the VIEs reach a cumulative level of profitability, because our PRC subsidiaries occupy certain trademarks and copyrights, the agreements will be updated to reflect charges for such trademarks and copyrights usage on the basis that they will qualify for tax neutral treatment.

China's Enterprise Income Tax Law imposes a withholding income tax of 10% on dividends distributed by a Foreign Invested Enterprises, or the FIE, to its immediate holding company outside of China. A lower withholding income tax rate of 5% is applied if the FIE's immediate holding company is registered in Hong Kong or other jurisdictions that have a tax treaty arrangement with China, subject to a qualification review at the time of the distribution. For the purpose of this hypothetical example, this table has been prepared based on a taxation scenario under which the full withholding tax would be applied. In addition, this table has been prepared under the assumption that all profits of the VIEs will be distributed as fees to our PRC subsidiaries under tax neutral contractual arrangements. If in the future, the accumulated earnings of the VIEs exceed the fees paid to our PRC subsidiaries, or if the current and contemplated fee structure between the intercompany entities is determined to be non-substantive and disallowed by Chinese tax authorities, we have other tax-planning strategies that can be deployed on a tax neutral basis. Should all tax planning strategies fail, the VIEs could, as a matter of last resort, make a non-deductible transfer to our PRC subsidiaries for the amounts of the stranded cash in the VIEs. This would result in the double taxation of earnings: one at the VIE level (for non-deductible expenses) and one at the PRC subsidiary level (for presumptive earnings on the transfer). Such a transfer and the related tax burdens would reduce our after-tax income to approximately 50.6% of the pre-tax income. The Group's management is of the view that the likelihood that this scenario would happen is remote.

**Restrictions on Foreign Exchange and the Ability to Transfer Cash between Entities, Across Borders and to U.S. Investors**

------

Sunlands Technology Group's ability to pay dividends, if any, to its shareholders and ADS holders and to service any debt it may incur will depend upon dividends paid by our PRC subsidiaries. Under PRC laws and regulations, our PRC subsidiaries are subject to certain restrictions with respect to paying dividends or otherwise transferring any of their net assets offshore to Sunlands Technology Group. In particular, under the current effective PRC laws and regulations, dividends may be paid only out of distributable profits. Distributable profits are the net profit as determined under PRC GAAP, less any recovery of accumulated losses and appropriations to statutory and other reserves required to be made. Each of our PRC subsidiaries is required to set aside at least 10% of its after-tax profits each year, after making up previous years' accumulated losses, if any, to fund certain statutory reserve funds, until the aggregate amount of such a fund reaches 50% of its registered capital. As a result, our PRC subsidiaries may not have sufficient distributable profits to pay dividends to us in the near future.

Furthermore, if certain procedural requirements are satisfied, the payment of current account items, including profit distributions and trade and service-related foreign exchange transactions, can be made in foreign currencies without prior approval from State Administration of Foreign Exchange, or the SAFE, or its local branches. However, 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, approval from or registration with competent government authorities or its authorized banks is required. The PRC government may take measures at its discretion from time to time to restrict access to foreign currencies for current account or capital account transactions. If the foreign exchange control system prevents the Group from obtaining sufficient foreign currencies to satisfy the Group's foreign currency demands, the Group may not be able to pay dividends in foreign currencies to our offshore intermediary holding companies or ultimate parent company, and therefore, our shareholders or investors in the ADSs. Further, we cannot assure you that new regulations or policies will not be promulgated in the future, which may further restrict the remittance of Renminbi into or out of the PRC. We cannot assure you, in light of the restrictions in place, or any amendment to be made from time to time, that our current or future PRC subsidiaries will be able to satisfy their respective payment obligations that are denominated in foreign currencies, including the remittance of dividends outside of the PRC. If any of our subsidiaries incurs debt on its own behalf in the future, the instruments governing such debt may restrict its ability to pay dividends to Sunlands Technology Group. In addition, our PRC subsidiaries are required to make appropriations to certain statutory reserve funds, which are not distributable as cash dividends except in the event of a solvent liquidation of the companies.

For PRC and United States federal income tax considerations of an investment in the ADSs, see "Item 10. Additional Information—10.E. Taxation."

**Impact of Holding Foreign Companies Accountable Act** 

Trading in our securities on U.S. markets, including the NYSE, may be prohibited under the Holding Foreign Companies Accountable Act (the "HFCAA") if the Public Company Accounting Oversight Board (the "PCAOB") determines that it is unable to inspect or investigate completely our auditor for two consecutive years. On December 16, 2021, the PCAOB issued the HFCAA Determination Report to notify the SEC of its determinations that the PCAOB was unable to inspect or investigate completely registered public accounting firms headquartered in mainland China and Hong Kong (the "2021 Determinations"), including our auditor. On May 26, 2022, we were conclusively identified by the SEC under the HFCAA as having filed audit reports issued by a registered public accounting firm that cannot be inspected or investigated completely by the PCAOB in connection with the filing of our 2021 Form 20-F. The inability of the PCAOB to conduct inspections in the past also deprived our investors of the benefits of such inspections. On December 15, 2022, the PCAOB announced that it was able to conduct inspections and investigations completely of PCAOB-registered public accounting firms headquartered in mainland China and Hong Kong in 2022. The PCAOB vacated its previous 2021 Determinations accordingly. As a result, we were not at risk of having our securities subject to trading prohibition under the HFCAA unless a new determination is made by the PCAOB. However, whether the PCAOB will continue to conduct inspections and investigations completely to its satisfaction of PCAOB-registered public accounting firms headquartered in mainland China and Hong Kong is subject to uncertainty and depends on a number of factors out of our, and our auditor's, control, including positions taken by authorities of the PRC. The PCAOB is expected to continue to demand complete access to inspections and investigations against accounting firms headquartered in mainland China and Hong Kong in the future and states that it has already made plans to resume regular inspections going forward. The PCAOB is required under the HFCAA to make its determination on an annual basis with regards to its ability to inspect and investigate completely accounting firms based in the mainland China and Hong Kong. The possibility of being a "Commission-Identified Issuer" and risk of delisting could continue to adversely affect the trading price of our securities. If the PCAOB determines in the future that it no longer has full access to inspect and investigate accounting firms headquartered in mainland China and Hong Kong and we continue to use such accounting firm to conduct audit work, we would be identified as a "Commission-Identified Issuer" under the HFCAA following the filing of the annual report for the relevant fiscal year, and if we were so identified for two consecutive years, trading in our securities on U.S. markets would be prohibited. For details, see "Item 3. Key Information—3.D Risk Factors—Risks Related to Doing Business in China—The ADSs will be delisted and the ADSs and shares will be prohibited from trading in the United States under the Holding Foreign Companies Accountable Act, or the HFCAA, if the PCAOB is unable to inspect or investigate completely auditors located in China for two consecutive years."

**3. B. Capitalization and Indebtedness**

Not applicable.

**3. C. Reason for the Offer and Use of Proceeds**

Not applicable.

**3. D. Risk Factors**

The Group faces various legal and operational risks and uncertainties as a group based in and primarily operating in China. The PRC government has significant authority to exert influence on the ability of China-based issuers, like us, to conduct its business, accept foreign investments or be listed on a U.S. stock exchange. For example, the Group faces risks associated with regulatory approvals of offshore offerings, anti-monopoly regulatory actions, cybersecurity and data privacy, as well as the uncertainty on whether the PCAOB will continue to be able to satisfactorily inspect or investigate completely registered public accounting firms headquartered in mainland China and Hong Kong. The PRC government may also intervene with or influence the Group's operations as the government deems appropriate to further regulatory, political and societal goals. The PRC government has recently published new policies that significantly affected educational industry and we cannot rule out the possibility that it will in the future further release regulations or policies regarding educational industry that could adversely affect the Group's business, financial condition and results of operations. Any such action, once taken by the PRC government, could significantly limit or completely hinder the Group's ability to offer or continue to offer securities to investors and cause the value of such securities to significantly decline or in extreme cases, become worthless. Furthermore, Sunlands Technology Group is a Cayman Islands holding company. The Group's operations in China are conducted through our PRC subsidiaries and the VIEs. Thus, the Group's corporate structure involves unique risks to investors in the ADSs.

You should carefully consider all of the information in this annual report before making an investment in the ADSs. Below please find a summary of the principal risks and uncertainties the Group faces, organized under relevant headings. In particular, as we are a China-based issuer incorporated in the Cayman Islands, you should pay special attention to subsections headed "Item 3. Key Information—3.D. Risk Factors—Risks Related to Doing Business in China" and "Item 3. Key Information—3.D. Risk Factors—Risks Related to Our Corporate Structure."

For details, please see page 42 and 43.*

&nbsp;&nbsp;&nbsp;&nbsp;•*The PRC government's significant oversight over the Group's business operation in China could result in a material adverse change in the Group's operations in China and the value of the ADSs. The Chinese government may intervene or influence the Group's operations in China at any time, or may exert more regulation over offerings conducted overseas and/or foreign investment in China-based issuers. Any actions by the Chinese government to exert more oversight and regulation over offerings that are conducted overseas and/or foreign investment in China-based issuers could significantly limit or completely hinder our ability to offer or continue to offer securities to investors and cause the value of such securities to significantly decline or become worthless. For details, please see pages 43.*

&nbsp;&nbsp;&nbsp;&nbsp;•*You may experience difficulties in effecting service of legal process, enforcing foreign judgments or bringing actions in China, including Hong Kong, against the Group or the Group's management named in the annual report based on foreign laws.

Key Information—Restrictions on Foreign Exchange and the Ability to Transfer Cash between Entities, Across Borders and to U.S. Investors" on page 17 for more information.*

&nbsp;&nbsp;&nbsp;&nbsp;•*The PCAOB had previously been unable to inspect our auditor in relation to their audit work performed for the Group's financial statements, and any future inability to do so would deprive our investors of the benefits of such inspections. For details, please see page 48 and 49.*

&nbsp;&nbsp;&nbsp;&nbsp;•*The ADSs will be delisted and the ADSs and shares will be prohibited from trading in the United States under the Holding Foreign Companies Accountable Act, or the HFCAA, if the PCAOB is unable to inspect or investigate completely auditors located in China for two consecutive years. For details, please see pages 49.*

**Risks Related to the Group's Business** 

***If the Group fails to increase student enrollments, the Group's net revenues may decline, and the Group may not be able to maintain growth.***

The Group generates revenue primarily from the tuition the Group collects from students. It is critical for the Group to enroll prospective students in a cost-effective manner. Some of the factors, many of which are largely beyond the Group's control, could prevent the Group 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 interests, certifications, professions, skills, degrees or diplomas 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 the Group is 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 the Group's services, the Group's student enrollments could be negatively affected or the Group's costs associated with student acquisition and retention could increase, or both, any of which could materially affect the Group's ability to grow the Group's gross billings and net revenues. These developments could also harm the Group's brand and reputation, which would negatively impact the Group's ability to expand the Group's business.

***If the Group fails to manage its business growth effectively, the success of the Group's business model will be compromised.***

The Group's growth strategy has placed, and will continue to place, a significant strain on the Group's sales and marketing capacities, administrative and operating infrastructure, facilities and other resources. To maintain the Group's growth, the Group needs to continue to acquire more students, scale up the Group's course offerings, increase the Group's academic and administrative faculty, as well as strengthen the Group's platforms and systems. The Group will also be required to refine the Group's operational, financial and management controls and reporting systems and procedures. If the Group fails to efficiently manage the Group's business expansion, the Group's costs and expenses may increase more than the Group plans and the Group 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 the Group's business plans. In addition, the Group may, as part of carrying out the Group's 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 the Group's existing and prospective students, in which case their experience with the Group's education services may suffer, which could damage the Group's reputation and business prospect.

The Group's ability to effectively implement the Group's strategies and manage the Group's business growth will depend on a number of factors, including the Group's ability to: (i) identify and effectively market the Group's 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, including working adult students; (iii) maintain and increase the Group's student enrollments; (iv) effectively recruit, train and motivate a large number of new employees, including the Group's faculty members and sales and marketing personnel; (v) successfully implement enhancements and improvements to the systems and platforms; (vi) continue to improve the Group's operational, financial and management controls and efficiencies; (vii) protect and further develop the Group's 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 the Group's growth will continue to place significant demands on the Group's management. There are no guarantees that the Group will be able to effectively manage any future growth in an efficient, cost-effective and timely manner, or at all. The Group's growth in a relatively short period of time is not necessarily indicative of results that the Group may achieve in the future. If the Group does not effectively manage the growth of the Group's business and operations, the Group's reputation, results of operations and

------

overall business and prospects could be negatively impacted.

The Group's net revenues were RMB2,159.6 million, RMB1,990.2 million and RMB2,019.9 million (US$288.8 million), respectively, in 2023, 2024 and 2025. During the same periods, the Group's gross billings were RMB1,504.6 million, RMB1,555.4 million and RMB1,467.4 million (US$209.8 million), respectively, and the Group's new student enrollments were 616,341, 674,649 and 579,788, respectively. The Group is seeking to offer a broader range of courses, foster a more social and entertaining learning experience, and use cutting-edge technologies to improve students' learning experience and outcomes. All of these endeavors involve risks and will require significant management, financial and human resources. We cannot assure you that they will achieve the anticipated results or that the Group's gross billings and new student enrollments will not decline in the future due to the risks and uncertainties discussed in this "Item 3. Key Information—3.D. Risk Factors." If the Group is not able to achieve growth in the Group's gross billings and new student enrollments effectively, or at all, the Group's business and prospects may be materially and adversely affected.

***The Group is subject to the uncertainty to continue to achieve profitability in the future.***

The Group had net income of RMB640.8 million, RMB342.1 million and RMB365.6 million (US$52.3 million) in 2023, 2024 and 2025, respectively. Historically, the Group had recorded net losses. We cannot assure you that the Group will be able to continue to generate net profits in the future.

The Group intends to continue to invest heavily for the foreseeable future in increasing the Group's market share, improving the capacity of the Group's 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 the Group expects and the Group's net revenues may not increase sufficiently to offset these expenses. The Group 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 the Group will eventually achieve the Group's intended long-term benefits or profitability. These factors, among others set out in this "Item 3. Key Information—3.D. Risk Factors," may negatively affect the Group's ability to achieve profitability in the near term, if at all.

***If the Group is unable to conduct sales and marketing activities cost-effectively, the Group's results of operations and financial condition may be materially and adversely affected.***

The Group relies on its sales and marketing efforts to increase student enrollments. The Group's sales and marketing expenses primarily include expenses incurred in relation to sales and marketing personnel and marketing spending. The Group incurred approximately RMB1,142.2 million, RMB1,216.9 million and RMB1,137.6 million (US$162.7 million), respectively, in sales and marketing expenses in 2023, 2024 and 2025.

The Group's sales and marketing activities may not be well received by the market and may not result in the levels of sales that the Group anticipates. The Group also may not be able to retain or engage a sufficient number of experienced sales and marketing personnel, or to train newly onboard sales and marketing personnel, which we believe is critical to implementing the Group's sales and marketing strategies cost-effectively. Further, sales and marketing approaches and tools in China's online education market are evolving rapidly. This requires the Group to continually enhance its sales and marketing approaches and experiment with new methods to keep pace with industry developments and student preferences. Moreover, the Group's sales and marketing activities may be deemed to violate PRC laws and regulations, and the Group may be exposed to administrative penalties, such as paying fines or publishing explanatory notes to limit the adverse effects of the Group's marketing efforts. If deemed guilty of significant infringements, the Group may be ordered to cease sales and marketing activities temporarily and the Group's business license may be revoked. Failure to engage in sales and marketing activities in a compliant and cost-effective manner may reduce the Group's market share, cause the Group's revenues and gross billings to decline, negatively impact the Group's profitability, and materially harm the Group's business, financial condition and results of operations.

***The Group may be adversely affected by any negative publicity concerning the Group and the Group's business, shareholders, affiliates, directors, officers and employees and the industry in which the Group operates, regardless of its accuracy, which could harm the Group's reputation and business.***

Negative publicity about the Group and the Group's business, shareholders, affiliates, directors, officers, and teachers and other employees, as well as the industry in which the Group operates, can harm the Group's operations. The Group has been exposed to negative publicity concerning refund dispute, administrative penalty, alleged improper or misleading statement made in the Group's sales and marketing activities, and student recruitment for unqualified institutions in the past. For example, the Group was reported to have recruited students from January 2021 to January 2022 for Morrison University in the state of Nevada. The recruitments were made pursuant to the Group's cooperation with a company in China (the "Partnering Company") claiming to have obtained authorization from Morrison University. It was revealed that the authorization was inauthentic and Morrison University had no legal right to operate within the state of Nevada. As of the date of this annual report, the Group is seeking to hold the Partnering Company liable through legal actions. The negative publicity surrounding this incident has and may in the future harm the Group's reputation. The Group may be

------

involved in disputes with the affected students, especially if the Group is not able to fulfil the Group's obligations under the agreements between the Group and the students. While the Group endeavors to ensure that the overseas institutions with whom the Group partners are qualified, we cannot assure you that the Group's partnering institutions will timely renew their necessary licenses or qualifications when they become due or that the Group will be able to identify any unqualified institutions accurately in a timely manner or at all.

Negative publicity concerning these parties could be related to a wide variety of matters, including, but are not limited to:

&nbsp;&nbsp;&nbsp;&nbsp;•alleged misconduct or other improper activities committed by students or the Group's directors, officers, and teachers and other employees, including misrepresentation made by the Group's employees to potential students during sales and marketing activities;

&nbsp;&nbsp;&nbsp;&nbsp;•false or malicious allegations or rumors about the Group or the Group's directors, shareholders, affiliates, officers, and teachers and other employees;

&nbsp;&nbsp;&nbsp;&nbsp;•complaints by students about the Group's education services and sales and marketing activities;

&nbsp;&nbsp;&nbsp;&nbsp;•tuition refund disputes between the Group and students or administrative penalties;

&nbsp;&nbsp;&nbsp;&nbsp;•security breaches of confidential student or employee information;

&nbsp;&nbsp;&nbsp;&nbsp;•employment-related claims relating to alleged employment discrimination, wage and hour violations; and

&nbsp;&nbsp;&nbsp;&nbsp;•governmental and regulatory investigations or penalties resulting from the Group's failure to comply with applicable laws and regulations.

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 the Group an opportunity for redress or correction. The opportunity for dissemination of information, including inaccurate information, is seemingly limitless and readily available. Information concerning the Group and the Group's 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 the Group's reputation, business, financial condition and results of operations.

***The Group faces risks associated with the lack of a private school operating permit for 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.***

Certain of our subsidiaries and the VIEs through which the Group operates its online education business, currently do not hold a private school operating permit, and the Group may be subject to risks of administrative sanctions due to the lack of such permit.

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.

In December 2016, several PRC government agencies, including the MOE, the State Administration for Industry and Commerce which has now merged into the newly-established State Administration for Market Regulation, or the SAMR, 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 SAMR, 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 "Item 4. Information on the Company—4.B. Business Overview—Regulation—Regulation Relating to Private Education—The Law for Promoting Private Education and its Implementing Rules."

As of the date of this annual report, the Group has not received any notice of warning or been subject to any penalties or disciplinary action from government authorities due to the lack of a private school operating permit for online education services. In April 2021, the State Council promulgated the Amended Regulations on the Implementation of Law for Promotion Private Education Law of PRC, or Amended Implementing Rules, which became effective on September 1, 2021. The Amended Implementing Rules provide, among others, that a private school engaging in online education activities using internet technology shall obtain an appropriate private school operating permit. The Amended Implementing Rules, however, do not specify whether an online tutoring service provider like the Group shall obtain such private school operating permit and what requirements that an online tutoring service provider like the Group need to

------

satisfy in order to obtain a private school operating permit, nor does it specify which level of government authority has the authority to accept and examine the Group's application for the private school operating permit. According to the Q&A published on the official website of Beijing Municipal Education Commission in April 2022, the education department is only responsible for the issues related to institutions providing academic subjects tutoring services for primary and secondary school. We cannot assure you that the PRC government will not in the future require the Group to obtain a private school operating permit. If the PRC government requires the Group to obtain a private school operating permit or introduces additional amendments and guidelines to expand the coverage of the Amendment or Amended Implementing Rules to explicitly cover online education service providers, and if the Group fails to do so, the Group 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 the lack of a private school operating permit. The Group may also be subject to regulatory requirements that are more stringent than the ones currently applicable to the Group, 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 the Group to obtain and maintain additional licenses and permits, and the Group may incur substantial expenses or alter or change the Group's business to comply with these requirements. For example, pursuant to the Interim Measures of Wuhan for the Administration of Private Training Institutions promulgated by Wuhan Municipal Government effective on March 15, 2018, private training institutions shall abide by the following provisions with respect of refund fees: (i) if a student requires a refund before the beginning of the course, the institution shall refund all the fees paid to it with deduction of the educational service fees and other fees actually incurred; (ii) if a student requires a refund after the beginning of the course, the institution shall refund the remaining part of the fees after deducting the corresponding proportion of the tuition fees, the fees for collection and management and the relevant taxes and fees in accordance with the proportion of the class hours completed; (iii) where an institution fails to fulfill the commitments with the student, and the student requires a refund, the institution shall refund all the fees paid by the student; and (iv) the institution shall complete the examination and verification within three working days upon the receipt of the refund requirement and shall refund to the student within 30 days. It is uncertain as to whether and how such measures and rules would be applicable to the Group, and whether any future laws and regulations with respect to the tuition refund requirements for online education service providers like the Group will be introduced. The Group has been exposed to refund dispute between the Group and students in the past. We cannot assure you that if the Group is subject to more stringent refund regulatory requirements, the Group can adjust the Group's refund policy to comply with these requirements on a timely manner, which may cause the Group's more refund disputes with students and may have a material and adverse effect on the Group's business, operating results and financial condition.

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 SAMR. If the Group was required to expand the authorized scope of the Group's business license to cover the Group's business of online education services, which shall be registered with the SAMR, to comply with applicable licensing requirements, the Group may not able to do so before the Group has obtained a private school operating permit. If any of the foregoing were to happen, the Group's business operations may be disrupted, and the Group's financial condition, results of operations and reputation may be materially and adversely affected.

Moreover, the MOE, jointly with certain other PRC government authorities, promulgated the Opinions on Guiding and Regulating the Orderly and Healthy Development of Educational Mobile Apps on August 10, 2019, or the Opinions on Educational Apps, which requires, among others, mobile apps that offer services for school teaching and management, student learning and student life, or home-school interactions, with school faculty, students or parents as the main users, and with education or learning as the main application scenarios, be filed with the competent provincial regulatory authorities for education before the end of 2019. Subsequently, on November 11, 2019, MOE issued the Administrative Measures on Filing of Educational Mobile Apps, which requires, among others, that educational mobile app providers shall file their educational mobile apps and that filings of existing educational mobile apps shall be completed before January 31, 2020. See "Item 4. Information on the Company—4.B. Business Overview—Regulation—Regulations on Online and Distance Education." The educational mobile apps Shangde Jigou and Shangde Zikao had been filed with competent regulatory authority as required under the Opinions on Educational Apps. However, as the Opinions on Educational Apps are relatively new and evolving, and the Group's business model and practices are continuing to evolve and adapt, we cannot assure you that the Group will be in full compliance with all applicable laws, regulations and rules. Additionally, the Group may face challenges in completing or maintaining required filings for any new educational apps it introduces in the future in a timely manner, or at all. For example, as of the date of this annual report, the filings of certain of our or the VIEs' educational mobile apps, such as Jixiang Jiaoyu, Shufan Jiaoyu, Zhizi Ketang, Tiantian Bannixue, Lexueyun Ketang and Qingzhou Yun Ketang, have not been completed. If the Group fails to promptly complete such filing and comply with other applicable regulatory requirements, the Group may be blacklisted by the MOE or its local counterparts and prohibited from submitting any filings for six months, or may be subject to fines, regulatory orders to suspend the Group's operations or other regulatory and disciplinary sanctions.

In addition to the existing regulatory regime, it is uncertain whether and how the PRC government would promulgate additional laws and regulations regarding the online education industry, and there is no assurance that the Group can comply with any such newly promulgated laws and regulations in a timely manner, or at all. The Group's failure to fully comply

------

with these existing and future laws and regulations may materially and adversely affect the Group's business, financial condition and results of operations.

***We are subject to risks and uncertainties associated with the PRC laws, regulations and policies on the broader education industry.***

The education industry in China is highly regulated and subject to ongoing policy changes, creating uncertainties that could impact our business, financial condition, and results of operations. The PRC government has implemented strict regulatory oversight over the private education sector in recent years, particularly in areas such as after-school tutoring, vocational training, and online education. Future changes in laws, regulations, or enforcement practices could create new compliance challenges for market participants, including our business.

While the Group's primary focus is adult online education, the most restrictive policies, such as the Opinions on Further Alleviating the Burden of Homework and After-School Tutoring for Students in Compulsory Education (the Alleviating Burden Opinion) introduced in 2021, are primarily targeted at K-12 after-school tutoring, the broader regulatory environment for private education is evolving and subject to change. The regulatory authorities may introduce new requirements, restrictions or compliance obligations that could directly or indirectly affect our business operations.

As of the date of this annual report, the Group's business, financial condition, results of operations and prospect have not been materially and adversely affected by recent regulatory changes in the PRC private education industry. It is uncertain whether and how the PRC government would introduce additional laws, regulations and guidance that may impact adult education, vocational training, or other aspects of our business. If new regulations impose stricter operational, financial, or ethical standards, or if the authorities expand their enforcement efforts, we may be required to adjust our business model, obtain new approvals, or modify our service offerings, which could lead to increased compliance costs, operational disruptions, or limitations on our growth prospects. Due to the complexity and uncertainty of the regulatory environment, we cannot assure you that the Group will be in full compliance with newly introduced laws and regulations in a timely manner, or at all. Failure to regain compliance may subject the Group to fines or other penalties or be required to terminate certain operations, in which case the Group's business, financial condition and results of operations could be materially and adversely affected further. For more details of the relevant laws and regulations, please refer to "Item 4. Information on the Company—4.B. Business Overview—Regulation."

***The Group faces regulatory risks and uncertainties associated with the Group's teachers' lack of teaching licenses.***

Pursuant to the Amended Implementing Rules and 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 the Group's teachers currently do not hold teaching licenses.

As of the date of this annual report, the Group has 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. The current PRC laws and regulations, including the Amendment, the Amended Implementing Rules and the Implementation Rules, remain unclear as to whether the teachers of an online education service provider who provides adult online education and adult personal interest learning education like the Group 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 the Group's 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 the Group's teachers are not able to apply for and obtain the teaching licenses on a timely basis, or at all, the Group may be ordered to rectify such noncompliance or subject to penalties under the then-effective PRC laws and regulations, in which case the Group's business may be disrupted, and the Group's financial condition, reputation and prospects would be materially and adversely affected.

***The Group faces 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 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 "Item 4. Information on the Company—4.B. Business Overview—Regulation—Regulations Relating to Online Transmission of Audio-Visual Programs."

The Group delivers courses in live streaming format. The Group's teachers and students communicate and interact live with each other via the Group's 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 the Group transmits distinguishes the Group 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 the Group's offering of the courses. However, we cannot assure you that the competent PRC government authorities will not ultimately take a view contrary to the Group's opinion. In addition, the Group also offers video recordings of live streaming courses and certain other audio-video contents on the Group's online platforms to students as supplementary course materials. If the government authorities determine that the Group's offering of the courses fall within the relevant category of Internet audio-visual program services under the Categories, the Group 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. The Group has made inquiries to the relevant bureaus of SAPPRFT and was 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 the Group's platforms are subject to the Audio-Visual Program Provisions. The Group currently does not hold a License for Online Transmission of Audio-Visual Programs. If the PRC government determines that the Group's content should be considered as "internet audio-visual programs" for the purpose of the Audio-Visual Program Provisions, the Group may be required to obtain a License for Online Transmission of Audio-Visual Programs. The Group is, however, not eligible to apply for such license since the Group is not a state-owned or state-controlled entity. If this were to occur, the Group may be subject to penalties, fines, legal sanctions or an order to suspend the provision of the Group's live streaming courses. As of the date of this annual report, the Group has 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 the Group's business.

***The failure to obtain and maintain other approvals, licenses, permits or filings applicable to the Group's business could have a material adverse impact on the Group's business, financial conditions and results of operations.***

A number of PRC regulatory authorities, such as the SAMR, 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 the Group's business operations, and the Group is required to obtain a wide range of government approvals, licenses, permits and filings in connection with the Group's operations.

The Group currently does not hold several approvals, licenses and permits that may be required for certain aspects of the Group's business operations. Under the current PRC laws and regulations, the provision of the Group's educational content through the Group's online platform may be considered "online publishing" and may require the Group to obtain an Internet Publishing License, which the Group currently does not have. See "Item 4. Information on the Company—4.B. Business Overview—Regulation—Regulations Relating to Online Publishing." As of the date of this annual report, the Group has not received any notice of warning or been subject to any penalties or disciplinary action from government authorities due to the lack of an Internet Publishing License for online education services.

One of our subsidiaries, Wuhan Shangde, has registered "computer technology training" and "art training" in its authorized scope of business. However, the VIEs and certain of their operating subsidiaries currently do not include "occupational training" and "educational facilitation services" in their authorized scope of business. Based on the Group's consultation with the competent government authorities in Beijing, 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 "—The Group faces risks associated with the lack of a private school operating permit for 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." Even if the 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. Furthermore, certain of the VIEs and their operating subsidiaries that engage in online educational services may be required by relevant government authorities to obtain the Value-Added Telecommunications Business Operating License and the License for the Production and Operation of Radio and Television Program. In addition, certain mobile apps do not complete the filing procedures under the Notice on the Filing of Mobile Internet Apps. The Group and/or third parties post information on the Group's mobile apps and websites that may be viewed as news information, and the release of such

------

information on the Group's mobile apps and websites may be deemed as Internet news information services and therefore require the VIEs or their operating subsidiaries to obtain Internet news information licenses. In addition, if the government authorities deem printing and providing physical education materials to users as "publication distribution" under Administrative Provisions on the Publications Market, we, the VIEs or their operating subsidiaries may be required to obtain the Publication License. Furthermore, although certain of the VIEs and their operating subsidiaries have obtained the Value-Added Telecommunications Business Operating License, also known as the ICP License, that specifically permits such VIEs to provide certain internet information services, due to uncertainties with respect to the interpretation of relevant laws and regulations by PRC government authorities, we cannot assure you that such ICP License covers all the telecommunication services the VIEs and their operating subsidiaries currently provide, and in the event that such ICP License is found not to cover all the telecommunication services the VIEs and their operating subsidiaries currently provide, the VIEs and their operating subsidiaries may be required to obtain an additional Value-Added Telecommunications Business Operating License or to update their existing ICP License. If it comes to the attention of the government authorities that the VIEs and their operating subsidiaries are operating beyond their respective authorized scope of business, the Group may be subject to fines, confiscation of the gains derived from the noncompliant operations, or may be required to cease the VIEs' noncompliant operations. In addition, the Group delivers courses in live streaming format on the Group's proprietary live streaming platform which the relevant authorities may regard as a live-streaming platform and may thus require the Group to make necessary filings as a live-streaming platform. See "Item 4. Information on the Company—4.B. Business Overview—Regulation—Regulations Relating to Internet Live Streaming Services."

As of the date of this annual report, the Group has not been subject to any fines or other form of regulatory or administrative penalties or sanctions due to the lack of any aforementioned approvals, licenses or, permits or filings. However, we cannot guarantee that the government authorities will not impose any penalties or sanctions on the Group 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, permits or filings 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, approvals and/or filings for the operation of any of the Group's existing or future business. Besides, the Group may develop new business lines or change the operations of certain of the Group's current business among our PRC subsidiaries or the VIEs, which may require the Group to obtain additional licenses, approvals, permits, registrations and filings while there can be no assurance that the Group is able to successfully obtain such licenses, approvals, permits, registrations and filings in a timely manner or at all. In addition, there can be no assurance that the Group will be able to maintain their existing licenses, approvals, registrations or permits necessary to provide the Group's current online services in China, renew any of them when their current term expires, or update existing licenses or obtain additional licenses, approvals, permits, registrations or filings necessary for the Group's business expansion from time to time. If the Group is unable to obtain or maintain such licenses, permits, approvals or filings in a timely fashion, the Group could be subject to penalties and operational disruption and the Group's financial condition and results of operations could be adversely affected.

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

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

Additionally, given the interactive nature of the Group's live streaming lessons, the Group tends 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, the Group must provide candidates with competitive compensation packages and offer attractive career development opportunities. Although the Group has not experienced major difficulties in recruiting or training qualified teachers and mentors in the past, we cannot guarantee the Group will be able to continue to recruit, train and retain a sufficient number of qualified faculty members in the future as the Group continues to expand course offerings and business scale, which may have a material adverse effect on the Group's business, financial condition and results of operations.

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

The Group regularly and constantly updates existing courses and educational content and develops new courses and educational content to meet student's demand and the latest market trends. The revisions, improvements and expansions of 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 the Group is able to develop acceptable new course and educational content offerings, the Group may not be able to introduce them as quickly as students require or as quickly as the Group's 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 the Group 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 the Group is unsuccessful in pursuing course and educational content development and upgrading opportunities due to the financial constraints, failure to attract qualified faculty, or other factors, the Group's ability to attract and retain students could be impaired and the Group's financial results could suffer.

***The Group faces risks associated with the online live streaming course delivery model.***

We believe that, even with the proliferation of internet and mobile devices in China, some of the Group's target students may still be inclined to choose traditional face-to-face lessons offered by offline learning providers over online courses as they find the former more intimate and reliable. We cannot assure you that the Group's live streaming course delivery format will continue to be attractive to students in the future. If the Group's live streaming course delivery model becomes less appealing to students, the Group's business and prospects may be affected. In addition, there is no assurance that the Group's live streaming capacity will be able to support a growing number of students accessing the Group's courses online without any service interruptions. Furthermore, we cannot assure that the Group will be able to address PRC regulatory and legislative developments relating to online streaming business. See "—The Group faces regulatory risks and uncertainties with respect to the licensing requirement for the online transmission of internet audio-visual programs" and "—The failure to obtain and maintain other approvals, licenses, permits or filings applicable to the Group's business could have a material adverse impact on the Group's business, financial conditions and results of operations."

***The Group is subject to the risks associated with third-party live streaming service providers.***

Currently, while the Group relies on the proprietary live streaming platform to deliver online courses, the Group also uses certain third-party vendors to provide live streaming services to support the Group's 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 the Group to be unable to deliver the Group's courses in a live streaming format, forcing the Group to resort to using prerecorded lectures. The Group's inability to deliver live streaming courses during service interruptions may damage the quality of the Group's education service and student engagement and experience and negatively impact the Group's reputation, financial condition and results of operations.

The Group does not maintain long-term arrangements with the live streaming service providers, including the third-party service providers related to live streaming technologies and infrastructure. The term of the service agreements the Group enters into with third-party live streaming service providers are generally one year. If the Group 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 the Group with live streaming services at any time for any reasons, the Group's ability to deliver live streaming online courses will be severely impacted, and the students' learning experience and the Group's reputation will be harmed.

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

There have been continuous changes in the curriculum requirements associated with, and the format of, the exams the Group's 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 the Group to continually update and enhance the Group's course offerings, educational content and teaching methods. Any inability to track and respond to these changes in a timely and cost-effective manner would make the Group's education services less attractive to students, which may materially and adversely affect the Group's reputation and ability to continue to attract students without a significant decrease in the Group's tuition. In addition, as the Group further expands the course offerings, we cannot assure that the Group will be able to adapt the Group's existing educational content and methods to new courses that the Group has limited experience in teaching.

***The Group may face risks associated with the installment tuition payment plan the Group offers to its students.***

In 2015, the Group 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 3 to 12 months. Under the cooperation agreement between the Group and each credit provider, the Group is obligated to pay the full amount of interest payable under a loan to the credit providers. The Group does not provide any guarantees for the repayment of student loans in favor of the credit providers. In 2023, 2024 and 2025, the Group's student loan coverage ratio was 1.3%, 1.9% and 1.7%, respectively. For the same periods, the Group made interest payments of RMB1.5 million, RMB1.7 million and RMB1.9 million (US$0.3 million), respectively, to the credit providers. The decrease was mainly due to the students' preference for lump-sum payment for interest, professional skills and professional certification preparation courses.

However, the Group plans to continue to make the interest payments for students under their loans and pay service

------

fees to the credit providers, which may place strains on the Group's financial resources in the future. The Group may be subject to risks associated with an increase in interest rates to the extent that the Group continues to make interest payments for the loans taken by students. If the Group ceases to do so due to increases in interest rates or for other reasons, the Group's course packages may become more costly for students to purchase, which could in turn negatively impact the Group's business, financial condition and reputation.

The availability of funding from the Group's 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 students on the loans, and, where applicable, the availability of lenders on the credit providers' platforms. In addition, the Group's credit providers may seek to acquire borrowers independently instead of through cooperation with us. The Group currently works with a limited number of credit providers and we cannot assure you that the Group's credit providers will continue to cooperate with the Group 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 students' borrowing needs. If any of these were to occur, the Group's course packages may become less compelling to prospective students who wish to obtain student loans, and as a result the Group's business and financial condition may be negatively affected.

***Disruption to or failures of the Group's IT infrastructure could reduce student satisfaction and could harm the Group's operations.***

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

***The Group's business depends on the continued success of the Group's brand "Sunlands," and if the Group fails to maintain and enhance recognition of the Group's brand, the Group may face difficulty enrolling new students, and the Group's reputation and operating results may be harmed.***

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

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

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

***To the extent the Group relies on certain types of course offerings to generate revenues, the Group will be subject to concentration risks, including risks resulting from changes in government policies.***

The Group's reliance on certain types of course offerings may expose the Group to concentration risks. For example, the Group has historically relied on the Group's Self-taught Higher Education Examination, or the STE course offerings, to generate revenues. In recent years, the interest, professional skills and professional certification preparation course offerings have contributed to an increasing proportion of the Group's overall revenues. In 2023, 2024 and 2025, the Group's

------

interest, professional skills and professional certification preparation courses represented approximately 67.1%, 75.3% and 74.2%, respectively, of the Group's net revenues, and approximately 98.4%, 99.1% and 99.9%, respectively, of the Group's gross billings. In addition, the Group's interest, professional skills and professional certification preparation courses represented approximately 95.0%, 97.6% and 98.1%, respectively, of the Group's new student enrollments in 2023, 2024 and 2025.

The interest, professional skills and professional certification preparation course offerings include diversified course offerings, and thus we believe the Group currently is not reliant on certain types of course offerings for revenue generation. However, if the Group become reliant on certain types of course offerings to generate revenues in the future, and if there are significant reductions in the perceived value of any of the courses on which the Group relies significantly to generate the Group's revenues or gross billings, the demand for and attractiveness of the Group's course offerings may be adversely affected, which could have an adverse impact on the Group's financial condition and results of operations.

***If the Group fails to effectively identify, pursue and consummate strategic alliances or acquisitions, the Group's ability to grow and to achieve profitability could be impacted.***

The Group may from time to time engage in evaluations of, and discussions with, possible domestic and international acquisition or alliance candidates. The Group 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 the Group's expansion into new markets, and the Group's strategies may not succeed beyond the Group's current markets. If the Group are unable to effectively address these challenges, the Group's ability to execute acquisitions as a component of the Group's long-term strategy will be impaired, which could have an adverse effect on the Group's growth.

***The Group faces intense competition in the Group's industry, which could divert student to the Group's competitors, lead to pricing pressure and loss of market share, and significantly reduce the Group's gross billings and net revenues.***

China's adult online education market and adult personal interest learning market are intensely competitive. The Group competes 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 the Group's current and future competitors may have substantially greater name recognition and financial and other resources than the Group does, which may enable them to compete more effectively for potential students and decrease the Group's market share. The Group also expects to face competition as a result of new entrants to the adult online education market and the adult personal interest learning market.

The Group may not be able to compete successfully against current or future competitors and may face competitive pressures that could adversely affect the Group's business or results of operations. For example, increased competition may result in pricing pressure for the Group in terms of the tuition the Group 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 the Group's competitors may develop platforms or other technologies that are superior to the platform and technology the Group uses. These differences may affect the Group's ability to recruit and retain students, which may render the Group's online course offerings less competitive. The increasingly competitive landscape may also result in longer and more complex sales cycles with a prospective student or a decrease in the Group's market share, any of which could negatively affect the Group's gross billings and net revenues and the Group's ability to grow the Group's business.

***If the Group's security measures are breached or fail and result in unauthorized disclosure of data by the Group's employees or the Group's third-party agents, the Group 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 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, the Group faces an increasing number of threats to the Group's IT infrastructure, including unauthorized activity and access by the Group's employees or third-party agents, system viruses, worms, malicious code and organized cyberattacks, which could breach the Group's security and disrupt the Group's business. For example, the Group has introduced data security and confidentiality protocols into the cooperation agreements the Group enters into with third-party sales agents with whom the Group shares prospective students' contact information, and the Group has made technical improvements in the Group's IT infrastructure to prevent unauthorized access of confidential or sensitive personal information by the Group's employees and third-party sales agents in the process of engaging prospective students. These measures, however, may not be as effective as the Group anticipates. In addition, there is no assurance that the Group's third-party sales agents will comply with contractual and legal requirements with respect to data privacy when they collect data from the Group's prospective students. If the Group's

------

security measures are breached or fail as a result of third-party action, employee error, malfeasance or otherwise, the Group could be subject to liability or the Group's business could be interrupted, potentially over an extended period of time. Any or all of these issues could harm the Group's reputation, adversely affect the Group's ability to attract and enroll prospective students, cause prospective students not to enroll or stay enrolled, or subject the Group to third-party lawsuits, regulatory fines or other action or liability. Further, any reputational damage resulting from breach of the Group's security measures could create distrust of the Group's company by prospective students or investors. The Group 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 the Group's ability to collect and leverage the Group's user data and disclosure of user data could adversely impact the Group's business and reputation.***

In the ordinary course of the Group's business and in particular in connection with conducting sales and marketing activities with the Group's existing and prospective students as well as the utilization of the Group's personalized study programs, the Group collects and utilizes data supplied by the users. The Group currently faces certain legal obligations regarding the manner in which the Group treats such information. Increased regulation of data utilization practices, including self-regulation or findings under existing laws that limit the Group's ability to collect, transfer and use data, could have an adverse effect on the Group's business. While we have security measures in place to protect the data of the Group's users, the Group's study programs and underlying infrastructure may be materially damaged or compromised as a result of various factors, such as efforts by individuals or groups of hackers and sophisticated organizations, cyberattacks on the Group's internally built infrastructure, and vulnerabilities in systems and applications from third-party service providers. In addition, if the Group were to disclose data about the Group's users in a manner that was objectionable to them, the Group's business reputation could be adversely affected, and the Group could face potential legal claims and administrative penalties that could impact the Group's operating results. For further details, see "Item 4. Information on the Company—4.B. Business Overview—Data Privacy and Security" and "Item 16K. Cybersecurity."

Internationally, the Group may become subject to additional and/or more stringent legal obligations concerning the Group's 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 the Group to liability, and to the extent that the Group need to alter the Group's business model or practices to adapt to these obligations, the Group could incur additional expenses.

***The Group is subject to a variety of laws and other obligations regarding data protection, and any failure to comply with applicable laws and obligations could have a material adverse effect on the Group's business, financial condition and results of operations.***

The Group is subject to various regulatory requirements relating to the security and privacy of data, including restrictions on the collection, storage and use of personal information and requirements to take steps to prevent personal data from being divulged, stolen, or tampered with. See "Item 4. Information on the Company—4.B. Business Overview—Regulation—Regulations Relating to Internet Information Security and Privacy Protection." Regulatory requirements regarding the protection of data are constantly evolving and can be subject to differing interpretations or significant change, making the extent of the Group's responsibilities in that regard uncertain. For example, the Cyber Security Law of the PRC became effective in June 2017, but there are great uncertainties as to the interpretation and application of the law. It is possible that those regulatory requirements may be interpreted and applied in a manner that is inconsistent with the Group's practices. In addition, the Office of the Central Cyberspace Affairs Commission, the MIIT, the Ministry of Public Security, and the SAMR jointly issued an announcement on January 23, 2019 regarding carrying out special campaigns against mobile internet application programs collecting and using personal information in violation of applicable laws and regulations, which prohibits business operators from collecting personal information irrelevant to their services, or forcing users to give authorization in disguised manner. In addition, the PRC regulatory authorities have recently taken steps to strengthen the regulation on data protection and conducted several rounds of relevant inspections recently. The Group has been taking and will continue to take reasonable measures to comply with such announcement, provisions and inspection requirements.

On June 10, 2021, the Standing Committee of the National People's Congress promulgated the PRC Data Security Law, effective on September 1, 2021. On July 30, 2021, the State Council promulgated the Regulations on Critical Information Infrastructure Security Protection, which became effective on September 1, 2021. On August 20, 2021, the Standing Committee of the National People's Congress promulgated the PRC Personal Information Protection Law, which came into effect on November 1, 2021. In addition, on January 4, 2022, the CAC announced the adoption of the Revised Cybersecurity Review Measures, which became effective on February 15, 2022 and repealed the Cybersecurity Review Measures promulgated on April 13, 2020. Such Measures further restate and expand the applicable scope of the cybersecurity review. Pursuant to the Revised Cybersecurity Review Measures, critical information infrastructure operators that procure internet products and services, and network platform operators engaging in data processing activities, must be subject to the cybersecurity review if their activities affect or may affect national security. In addition, network platform operators holding over one million users' personal information shall apply with the Cybersecurity Review Office for a cybersecurity review before listing abroad. On January 4, 2022, the CAC published the Administrative Provisions on

------

Internet Information Service Algorithm Recommendation on its website, which became effective on March 1, 2022. Furthermore, on July 7, 2022, the CAC promulgated the Security Assessment Measures for Outbound Data Transfer, effective from September 1, 2022, to regulate outbound data transfer activities, protect the rights and interests of personal information, safeguard national security and social public interests, and promote the cross-border security and free flow of data. On March 22, 2024, the CAC published the Provisions on Promoting and Regulating Cross-bound Data Flows, which streamline and provide clarity to the governance framework for outbound data transfer.

These newly promulgated laws and regulations reflect PRC government further attempts to strengthen the legal protection for the national network security, data security, the security of critical information infrastructure and the security of personal information protection. For details on regulations over cybersecurity, data protection and privacy in the PRC, see "Item 4. Information on the Company—4.B. Business Overview—Regulation—Regulations Relating to Internet Information Security and Privacy Protection."

Based on the Group's understanding of the above PRC laws and regulations and assessment of our cybersecurity, data protection, and privacy practices, the Group's business operations do not violate any of the above PRC laws and regulations currently in force in all material aspects except for the uncertainties as disclosed in this annual report. The Group has not relied upon the opinion of PRC legal counsel with respect to its conclusion that the Group is compliant with PRC laws and regulations regarding cybersecurity, data protection, and privacy. As advised by Tian Yuan Law Firm, our PRC legal counsel, the Group is not legally required under PRC laws and regulations to engage an external legal counsel to conduct a review of its cybersecurity, data protection, and privacy practices in the PRC. The PRC laws and regulations impose enhanced compliance requirements for critical information infrastructure operators; however, as of the date of this annual report, the Group has not been identified by the PRC regulators as a "critical information infrastructure operator" under the relevant cybersecurity laws and regulations. Nevertheless, the Group strives to adhere to heightened standards of cybersecurity and data privacy for the interests of its users and shareholders, and accordingly the Group has established compliance procedures and programs to identify and mitigate risks in this regard. As a result, the Group's portal system, operation system and major mobile app have achieved scores of approximately 80 / 100 on tests conducted by independent third-party institutions, which speaks to effective measures adopted by the Group in compliance with applicable cybersecurity and data privacy laws and regulations. Therefore, we believe that the business operations of the Group do not violate any of the laws and regulations over cybersecurity and data privacy currently in force in any material aspect. However, should it become necessary or required under PRC laws and regulations, the Group will promptly engage external legal counsel to assess and provide an opinion on its compliance status with respect to cybersecurity and data privacy and disclose the findings of such review in accordance with SEC rules.

The Group has been taking and will continue to take reasonable measures to comply with the aforementioned laws, regulations, announcement, provisions and inspection requirements; however, as these laws, regulations, announcements and provisions are relatively new, and the related implementation rules have not yet been promulgated, it remains uncertain how these laws, regulations, announcements and provisions will be implemented. For example, there have been no clarifications from the relevant authorities as to the detailed standards for determining whether an activity is one that "affects or may affect national security", thus uncertainties remain as to whether the Groups' data processing activities shall be subject to a cybersecurity review. We cannot assure you the Group can adapt the operations to these laws, regulations, announcement and provisions in a timely manner. Evolving interpretations of such laws, regulations, announcements and provisions or any future regulatory changes might impose additional restrictions on or obligations of the Group generating and processing personal information and other data. The Group may be subject to additional regulations, laws and policies adopted by the PRC government to apply more stringent social and ethical standards in cybersecurity and data privacy resulting from the increased global focus on this area. To the extent that the Group needs to alter the Group's business model or practices to adapt to these announcement and provisions and future regulations, laws and policies, the Group could incur additional expenses.

Any failure, or perceived failure by the Group, or by third-party partners to maintain the security of students' data and other confidential information or to comply with applicable privacy, cybersecurity, data security and personal information protection laws, regulations, policies, contractual provisions, industry standards, and other requirements, may result in civil or regulatory liability, including governmental or data protection authority enforcement actions and investigations, fines, penalties, enforcement orders requiring the Group to cease operating in a certain way, litigation, or adverse publicity, and may require the Group to expend significant resources in responding to and defending allegations and claims. Moreover, claims or allegations that the Group has failed to adequately protect users' data, or otherwise violated applicable privacy, cybersecurity, data security and personal information protection laws, regulations, policies, contractual provisions, industry standards, or other requirements, may result in damage to the Group's reputation and a loss of confidence in the Group by users or partners, potentially causing the Group to lose users, business partners and revenues, which could have a material adverse effect on the Group's business, financial condition and results of operations. Furthermore, the PRC regulatory and enforcement regime with regard to privacy, cybersecurity, data security and personal information protection is still evolving. PRC regulators have been increasingly focused on regulation in the areas of cybersecurity, data security and data protection. We cannot assure you that relevant regulators will not interpret or implement these laws or regulations in ways that negatively affect the Group. It is possible that the Group may become subject to additional or new laws and regulations, policies and interpretations, which may result in additional expenses to the Group and subject the Group to potential liability and negative publicity. The Group expects that these areas will receive greater attention and focus from regulators, and

------

attract continued or greater public scrutiny and attention going forward, which could increase compliance costs and subject the Group to heightened risks and challenges associated with data security and protection. If the Group is unable to manage these risks, the Group could become subject to penalties, fines, suspension of business and revocation of required licenses, and the Group's reputation and results of operations could be materially and adversely affected.

***Tuition refunds or potential refund disputes may negatively affect the Group's cash flow, financial condition, and reputation.***

The Group offers different tuition refund options to students depending on the time of enrollment and subject to certain conditions and restrictions in the service contract between the Group and each student. 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 live streaming course lasting 30 minutes by reason of any material academic issue of the Group's courses within certain refund period, the Group offers a refund excluding the registration fees and the fees of delivered courses upon the Group's confirmation. In addition, the Group offers students a refund for the undelivered courses excluding the registration fees. Starting from June 2019, the Group offers such refund during the entire service period. When calculating gross billings for a specific period, the Group deducts the total amount of refunds from the total amount of cash received for the sale of course packages for such period. See "Item 4. Information on the Company—4.B. Business Overview—Tuition and Fees."

In 2023, 2024 and 2025, the Group had made RMB94.2 million, RMB76.3 million and RMB101.6 million (US$14.5 million) of refund payments, respectively, most of which were made pursuant to the Group's tuition refund policy, see "Item 4. Information on the Company—4.B. Business Overview—Tuition and Fees." The number of refund requests and the amount of refunds could be affected by a number of factors. These factors include, without limitation to, student dissatisfaction with the Group's teaching quality and the Group's course and educational content offerings, privacy concerns relating to the Group's online platforms, negative publicity regarding the Group or online education in general, the terms and scope of the Group's refund policy, and any change or development in PRC laws and regulations with respect to fees and tuitions charged by online education providers like the Group. See "—The Group faces risks associated with the lack of a private school operating permit for 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 Implementing Rules." As part of the Group's efforts to enhance user experience, from June 2019, the Group amended certain terms of refund policy to facilitate a more flexible and smoother refund process. Any refund payments that the Group may be required to make to the students, as well as the expenses the Group could incur for processing refunds and resolving refund disputes, could be substantial and could adversely affect the Group's gross billings, net revenues, liquidity and financial condition. A high volume of refunds and refund disputes may also generate negative publicity that could harm the Group's reputation. The Group has experienced in the past, and may experience in the future, negative publicity in relation to refund disputes between the Group and the students, which may significantly harm the Group's brand name and divert the Group's attention from operating business.

***We cannot assure you that the Group will not be subject to liability claims or legal or regulatory liability for any inappropriate or illegal content, which could subject the Group to liabilities and cause damages to the Group's reputation.***

Although the Group implements various monitoring procedures to identify and remove inappropriate or illegal content, we cannot assure you that there will be no inappropriate or illegal content included in the Group's content offerings including content generated and uploaded to the Group's online platforms by the users. For example, the Group has been historically penalized for inaccurate advertising. The Group may face civil, administrative or criminal liability or legal or regulatory sanctions, such as requiring the Group to restrict or discontinue the Group's content, products or services, if an individual or corporate, governmental or other entity believes that any of the content offerings violates any laws, regulations or governmental policies or infringes upon its legal rights. Even if such a claim were not successful, defending such a claim may cause the Group to incur substantial costs. Moreover, any accusation of inappropriate or illegal content in the Group's content offerings could lead to significant negative publicity, which could harm the Group's reputation, business, financial condition and results of operations.

***The Group's success depends on the continuing efforts of the Group's senior management team and other key employees.***

The Group depends 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 the Group's senior management or other key employees could harm the Group's business. Competition for qualified talents in China is intense. If one or more of the Group's senior management or other key employees are unable or unwilling to continue in their present positions, the Group may not be able to find replacements in a timely manner, or at all, and the Group's business may be disrupted. Moreover, if any member of the Group's senior management team or any of the Group's other key personnel joins a competitor or forms or invests in a competing business, the Group may lose student enrollments, qualified teaching faculty members and other key sales and marketing personnel to the Group's competitors. The Group's future success is

------

also dependent on the Group's ability to attract a significant number of qualified employees and retain existing key employees. If the Group is unable to do so, the Group's business and growth may be materially and adversely affected. The Group's need to significantly increase the number of qualified employees and retain key employees may cause the Group to materially increase compensation-related costs, including share-based compensation.

***If the Group cannot maintain the corporate culture as the Group grows, the Group could lose the innovation, collaboration and focus that contribute to the Group's business.***

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

***The Group may from time to time be subject to infringement claims relating to intellectual properties of third parties.***

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

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

***If the Group fails to protect the Group's intellectual property rights, the Group's brand and business may suffer.***

The Group relies on a combination of patent, copyright, trademark and trade secret laws and restrictions on disclosure to protect the Group's intellectual property rights. Although the Group seeks to obtain copyright or patent protection for the Group's intellectual property when applicable, it is possible that the Group may not be able to do so successfully or that the copyright or patent the Group has obtained may not be sufficient to protect all of the Group's intellectual property rights. In particular, the Group relies, to the great extent, upon the Group's 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 the Group's efforts to protect the proprietary education contents and other intellectual property rights, unauthorized parties may attempt to copy or duplicate the Group's intellectual property or otherwise use the Group's intellectual properties without obtaining the Group's consent. Monitoring unauthorized use of the Group's intellectual property is difficult and costly, and we cannot be certain that the steps the Group has taken will effectively prevent misappropriation of the Group's intellectual properties. If the Group is not successful in protecting the Group's intellectual property rights, the Group's business and results of operations may be adversely affected.

***The Group's students, employees and third-party vendors may engage in intentional or negligent misconduct or other improper activities or misuse the Group's platform, which could harm the Group's brand and reputation.***

The Group is exposed to the risk of fraud or other misconducts committed by students, employees and vendors, including certain third-party sales and marketing agencies. For example, in some instances, students and faculty members may post to the Group's 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 the Group to adopt and implement policies governing these practices. The Group 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 the Group to costly litigation and impose a significant strain on the Group's financial resources and attention of management personnel regardless of whether the claims have merit. The Group may be required to alter or cease the Group's uses of such materials, which may include changing or removing content from courses or altering the functionality of the Group's platform, or to pay monetary damages. Fraud or other misconducts by students, employees or third parties may also involve engaging in unauthorized misrepresentation to the Group's potential students and misappropriating

------

third-party intellectual property and other propitiatory rights during marketing activities, misusing sensitive personal information of 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 the Group's brand and reputation.

The Group's courses undergo multiple rounds of internal review before being broadly released. While the Group proactively monitors the live courses and other content and communications to ensure that the Group is able to identify content that may be deemed inappropriate or in violation of laws, regulations and government policies, since the Group has limited control over the real-time and offline behavior of the Group's users and employees, to the extent any improper behavior is associated with the Group's content and services, the Group's ability to protect its reputation may be limited. If any of the Group's users and employees suffer or allege to have suffered harm following contact initiated through the Group's services, the Group may face civil lawsuits or other liabilities. In response to allegations of illegal or inappropriate activities, PRC government authorities may intervene and hold the Group liable for non-compliance with PRC laws and regulations concerning the dissemination of information on the internet and subject the Group to administrative penalties or other sanctions, such as requiring the Group to restrict or discontinue the Group's content or services. As a result, the Group's business may suffer and the Group's reputation, business, financial condition and results of operations may be materially and adversely affected.

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

The Group has been, and in the future may be, the target of anti-competitive, harassing or other detrimental conduct by third parties including the Group's competitors. Such conduct may include complaints, anonymous or otherwise, to regulatory agencies regarding the Group's operations, accounting, business relationships, business prospects and business ethics. Additionally, allegations, directly or indirectly against the Group, may be posted online by anyone, whether or not related to the Group, on an anonymous basis. The Group 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 the Group will be able to conclusively refute each of the allegations within a reasonable period of time, or at all. The Group's reputation may also be materially negatively affected as a result of the public dissemination of anonymous allegations or malicious statements about the Group's business, which in turn may cause the Group to lose students and revenues, and adversely affect the price of the ADSs.

***The Group's user metrics and other estimates are subject to inaccuracy in measuring the Group's operating performance, which may harm the Group's reputation.***

The Group continually reviews the number of students, new student enrollments, gross billings per new student enrollment, and other operating metrics to evaluate growth trends, measure the Group's 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 the Group's 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 the Group's website and mobile application are used across a large student base. For example, the Group may not be able to identify individual students who have multiple accounts from multiple students who share one account on the Group's website or mobile application. In addition, the Group collects student reviews to measure student satisfaction rate and other student engagement metrics, but these reviews may not be representative of the Group's entire student population. Errors or inaccuracies in the Group's metrics or data could result in incorrect business decisions and inefficiencies. For instance, if a significant understatement or overstatement of student satisfaction or marketing spending were to occur, the Group might expend resources to implement unnecessary business measures or fail to take required actions to remedy an unfavorable trend. If investors do not perceive the Group's operating metrics to accurately represent the Group's operating performance, or if the Group discovers material inaccuracies in the Group's operating metrics, the Group's reputation may be harmed.

***If the Group fails to maintain an effective internal control over financial reporting, the Group may be unable to accurately and timely report our results of operations, meet our reporting obligations or prevent fraud and investor confidence in our company and the market price of the ADSs may decline.***

As a public company, we are subject to the Sarbanes-Oxley Act of 2002. Section 404 of the Sarbanes-Oxley Act of 2002 requires us to evaluate and determine the effectiveness of the Group's internal control over financial reporting, report any material weaknesses in such internal controls and provide a management report on internal control over financial reporting.

The Group's management has concluded that the Group's internal control over financial reporting was effective as of December 31, 2025. See "Item 15. Controls and Procedures—Management's Annual Report on Internal Control over Financial Reporting." We are exempt from the requirement of an attestation report issued by our registered public accounting firm because we are a non-accelerated filer. The Group will endeavor to maintain an effective internal control system, but any failure may cause the Group's management not be able to conclude that the Group has effective internal

------

control over financial reporting at a reasonable assurance level. To the extent the Group's independent registered public accounting firm is required to attest to, and report on, the effectiveness of the Group's internal control over financial reporting in the future, it may not be able to conclude that the Group has effective internal control over financial reporting at a reasonable assurance level. This could in turn result in the loss of investor confidence in the reliability of the Group's financial statements and negatively impact the trading price of the ADSs. Furthermore, the Group has incurred and may need to incur additional costs and use additional management and other resources in an effort to comply with Section 404 of the Sarbanes-Oxley Act and other requirements going forward.

In addition, there is no assurance that we or our auditor will not identify deficiencies in the Group's internal control over financial reporting that are deemed to be material weaknesses and render the Group's internal control over financial reporting ineffective for any future periods. If the Group fails to maintain the adequacy of its internal control over financial reporting, as these standards are modified, supplemented or amended from time to time, the Group may not be able to conclude on an ongoing basis that the Group has effective internal control over financial reporting in accordance with Section 404. Generally speaking, if the Group fails to achieve and to maintain effective internal control environment, we could suffer material misstatements in our financial statements and fail to meet our reporting obligations, which could 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 negative impact on the trading price of the ADSs. Additionally, ineffective internal control over financial reporting could expose the Group to increased risk of fraud or misuse of corporate assets and subject the Group to potential delisting from the NYSE, regulatory investigations and civil or criminal sanctions.

***We have incurred increased costs as a result of being a public company, particularly after we ceased to qualify as an "emerging growth company."***

We are a public company and expect to continue 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 U.S. Securities and Exchange Commission, or the SEC, and the NYSE, impose various requirements on the corporate governance practices of public companies. We will incur additional costs associated with our public company reporting requirements. It may also be more difficult for the Group to find qualified persons to serve on our board of directors or as executive officers. In addition, as we have ceased to be an "emerging growth company" as such term is defined in the JOBS Act, we expect to incur significant expenses and devote substantial management effort toward ensuring compliance with the requirements of Section 404 and the other rules and regulations of the SEC. We 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 the Group's 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 829,349 shares. As of the date of this annual report, options to purchase a total of 31,550 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.

***If the Group fails to make adequate contributions to various employee benefits plans as required by PRC regulations, the Group may be subject 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 the Group's 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. If the Group fails to make adequate contributions to various employee benefit plans and comply with applicable PRC labor-related laws, the Group may be subject to late payment penalties, and the Group could be required to make up the contributions for these plans as well as to pay late fees and fines. If the Group is subject to late fees or fines in relation to the underpaid employee benefits, the Group's financial condition and results of operations may be adversely affected. In addition, to the extent that the Group can make a reasonable estimate of the liability arising from the Group's failure in making full contributions to various employee benefit plans, the Group will record a related contingent liability. However, the amount of the Group's estimates may be inaccurate, in which case

------

the Group's financial condition and cash flow may be adversely affected if the Group were to pay late fees or fines in relation to the underpaid employee benefits.

***Increases in labor costs in the PRC may adversely affect the Group's 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 the Group needs to significantly reduce the Group's workforce, the PRC Labor Contract Law could adversely affect the Group's ability to do so in a timely and cost-effective manner, and the Group's results of operations could be adversely affected. In addition, for employees whose employment contracts include noncompetition terms, the PRC Labor Contract Law requires the Group to pay monthly compensation after such employment is terminated, which will increase the Group's operating expenses.

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

***The Group faces certain risks relating to the real properties that the Group leases.***

The Group leases real properties from third parties primarily for the Group's 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, the Group 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, the Group may be subject to fines imposed by PRC government authorities ranging from RMB1,000 and RMB10,000 for the Group's lease agreements that have not been registered with the relevant PRC governmental authorities.

As of the date of this annual report, the Group is not aware of any regulatory or governmental actions, claims or investigations being contemplated or any challenges by third parties to the Group's use of the Group's 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 impose fines on the Group due to the Group's failure to register any of the Group's lease agreements, which may negatively impact the Group's financial condition.

The Group leases real properties from third parties in China for marketing and providing offline consultation related to the Group's 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 the Group 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 the Group and the owners of such real properties decline to ratify the lease agreements between the Group and the respective lessors, the Group may not be able to enforce the Group's rights to lease such properties under the respective lease agreements against the owners. As of the date of this annual report, the Group is not aware of any claim or challenge brought by any third parties concerning the use of the Group's leased properties without obtaining proper ownership proof. If the Group's lease agreements are claimed as null and void by third parties who are the real owners of such leased real properties, the Group could be required to vacate the properties, in the event of which the Group 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 the Group is unable to relocate the Group's operations in a timely manner, the Group's operations may be interrupted.

***The Group's operations depend on the performance of the internet infrastructure and telecommunications networks in China.***

The successful operation of the Group's 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, the

------

Group has entered into contracts with various subsidiaries of a limited number of telecommunications service providers at provincial level and rely on them to provide the Group with data communications capacity through local telecommunications lines. The Group has 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. The Group's platform regularly serves a large number of users and advertisers. With the expansion of the Group's business, the Group may be required to upgrade the Group's technology and infrastructure to keep up with the increasing traffic on the Group's platform. However, the Group has no control over the costs of the services provided by telecommunications service providers. If the prices the Group pays for telecommunications and internet services rise significantly, the Group's results of operations may be materially and adversely affected. If internet access fees or other charges to internet users increase, the Group's user traffic may decline and the Group's business may be harmed.

***The Group may be subject to litigations, allegations, complaints and investigations from time to time arising out of business operations. We and certain of our directors and officers have been named as defendants in a shareholder class action lawsuit, which could have a material adverse impact on the Group's business, financial condition, results of operation, cash flows and reputation.***

The Group has been and may continue to be involved in legal and other disputes in the ordinary course of business operations. For example, we and certain of our directors and officers have been named as defendants in a class action lawsuit. For details, see "Item 8. Financial Information—8.A. Consolidated Statements and Other Financial Information—Legal Proceedings." We cannot guarantee that the Group will not be a target for lawsuits in the future, including putative class action lawsuits brought by shareholders. There can be no assurance that the Group will be able to prevail in the Group's defense or reverse any unfavorable judgment on appeal, and the Group may decide to settle lawsuits on unfavorable terms. Any adverse outcome of these cases, including any plaintiffs' appeal of the judgment in these cases, could result in payments of substantial monetary damages or fines, or changes to the Group's business practices, and thus have a material adverse effect on the Group's business, financial condition, results of operation, cash flows and reputation. In addition, there can be no assurance that the Group's insurance carriers will cover all or part of the defense costs, or any liabilities that may arise from these matters. The litigation process may utilize a significant portion of the Group's cash resources and divert management's attention from the day-to-day operations of our company, all of which could harm the Group's business. The Group also may be subject to claims for indemnification related to these matters, and the Group cannot predict the impact that indemnification claims may have on the Group's business or financial results.

***The Group currently does 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, the Group does not have any business liability or disruption insurance to cover the Group's operations. The Group has 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 the Group to have such insurance. Any uninsured business disruptions may result in the Group's incurring substantial costs and the diversion of resources, which could have an adverse effect on the Group's results of operations and financial condition.

***The Group faces risks related to natural disasters, extreme weather conditions, health epidemics and other catastrophic incidents, which could significantly disrupt the Group's 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 the Group's business in the future. If a disaster or other disruption were to occur in the future that affects the regions where the Group operates business, the Group's operations could be materially and adversely affected due to loss of personnel and damages to property. Even if the Group is not directly affected, such a disaster or disruption could affect the operations or financial condition of the Group's ecosystem participants, which could harm the Group's results of operations.

In addition, accidents, disasters and public health challenges in China and globally could impact the Group's business and results of operations. These types of events could negatively impact user activity and the Group's local operations, if any, in the affected regions, or, depending upon the severity, across China or globally, which could adversely impact the Group's business and results of operations.

**Risks Related to Our Corporate Structure**

***There are uncertainties regarding the interpretation and application of current and future PRC laws, regulations, and rules relating to the agreements that establish the VIE structure for the Group's operations in China, including potential future actions by the PRC government, which could affect the enforceability of our contractual arrangements with the VIEs and, consequently, significantly affect the Group's financial condition and results of operations. If the PRC government finds such agreements non-compliant with relevant PRC laws, regulations, and rules, or if these laws, regulations and rules or the interpretation thereof change in the future, we could be subject to*** 

------

***severe penalties or be forced to relinquish our interests in the VIEs.***

Foreign investment in the value-added telecommunication services industry in China is extensively regulated and subject to numerous restrictions. Pursuant to the latest list of special management measures for the market entry of foreign investment, or the Negative List, published by the National Development and Reform Commission and the Ministry of Commerce and effective on November 1, 2024, 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.

We are a Cayman Islands exempted 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, such business activities were conducted through the VIEs and their respective subsidiaries. Our wholly-owned subsidiaries in China have entered into a series of contractual arrangements with the VIEs, their respective shareholders and their respective subsidiaries, which enable us to (i) direct the activities of the VIEs that most significantly impact the VIEs' economic performance, (ii) receive substantially all of the economic benefits of the VIEs, and (iii) have an exclusive option to purchase all or part of the equity interests and assets in the VIEs when and to the extent permitted by PRC law. As a result of these contractual arrangements, we are considered the primary beneficiary of the VIEs for accounting purposes and are able to consolidate their operating results in the Group's financial statements under U.S. GAAP. See "Item 4. Information on the Company—4.C. Organizational Structure" for further details.

Since the laws and regulations are still evolving and new PRC laws, regulations, rules and interpretations may be introduced to impose additional requirements, posing additional challenges to our corporate structure and contractual arrangements, there are uncertainties regarding whether the Group could comply with new laws, regulations, rules and interpretations in a timely manner, or at all. Any failure to comply with such regulatory requirements may challenge the validity and enforceability of the Group's contractual arrangements.

If the PRC government finds that the Group's 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, the VIEs, or any of their subsidiaries are in violation of PRC laws or regulations or lack the necessary permits or licenses to operate the Group's business, the relevant PRC regulatory authorities, including the MIIT and SAMR, would have broad discretion in dealing with such violations or failures, including, without limitation:

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

&nbsp;&nbsp;&nbsp;&nbsp;•discontinuing or placing restrictions or onerous conditions on the Group' operation through any transactions between our PRC subsidiaries and the VIEs;

&nbsp;&nbsp;&nbsp;&nbsp;•imposing fines, confiscating the income from our PRC subsidiaries or the VIEs, or imposing other requirements with which the Group may not be able to comply;

&nbsp;&nbsp;&nbsp;&nbsp;•requiring the Group to restructure the Group's ownership structure or operations, including terminating the contractual arrangements with the VIEs and deregistering the equity pledges of the VIEs, which in turn would affect our ability to consolidate or derive economic interests from the VIEs; or

&nbsp;&nbsp;&nbsp;&nbsp;•restricting or prohibiting our use of the proceeds of our initial public offering to finance the Group's business and operations in China.

Any of these actions could cause significant disruptions to the Group's business operations and severely damage the Group's reputation, which would in turn materially and adversely affect the Group's business, financial condition and results of operations. In addition, new PRC laws, regulations, and rules may be introduced to impose additional requirements, posing additional challenges to the Group's corporate structure and contractual arrangements. If any of these occurrences results in our inability to direct the activities of the VIEs or our failure to receive the economic benefits from the VIEs and/or our inability to claim our contractual rights over the assets of the VIEs that conduct the Group's operations in China, we may not be able to consolidate the entity in our consolidated financial statements in accordance with U.S. GAAP, which could materially and adversely affect the Group's financial condition and results of operations and cause the ADSs to significantly decline in value or become worthless.

On February 17, 2023, the CSRC released the Trial Administrative Measures of Overseas Securities Offering and Listing by Domestic Companies, or the Overseas Listing Trial Measures, and five supporting guidelines, effective on March 31, 2023. At the press conference held for the Overseas Listing Trial Measures on the same day, officials from the CSRC clarified that, as for companies seeking overseas listing with contractual arrangements, the CSRC will solicit opinions from relevant regulatory authorities and complete the filing of the overseas listing of such companies if they duly meet the compliance requirements, and support the development and growth of these companies by enabling them to utilize two markets and two kinds of resources. If the Group fails to complete the filing with the CSRC in a timely manner or at all, for any future offerings, listing or any other capital raising activities, which are subject to the filings under the Overseas Listing Trial Measures, due to the Group's contractual arrangements, our ability to raise or utilize funds could be materially and adversely affected, and we may even need to unwind the Group's contractual arrangements or restructure the Group's business operations to rectify the failure to complete the filings. However, given that the Overseas Listing Trial Measures

------

were recently promulgated, there remain substantial uncertainties as to their interpretation, application, and enforcement and how they will affect the Group's operations and future financing.

***We rely on contractual arrangements with the VIEs and their respective shareholders for a significant portion of the Group's business operations which may not be as effective as direct ownership.***

We have relied and expect to continue to rely on contractual arrangements with the VIEs, their respective shareholders and their respective subsidiaries to operate the Group's online education services business in China. These contractual arrangements may not be as effective as direct ownership. For example, the VIEs and their respective 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 the VIEs and their respective subsidiaries constituted 63.4%, 83.9% and 48.5% of the Group's total net revenues in 2023, 2024 and 2025, respectively.

If we had direct ownership of the VIEs, we would be able to exercise our rights as a shareholder to effect changes in the board of directors of the VIEs, 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 the VIEs and their respective shareholders of their obligations under the contracts. The shareholders of the VIEs 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 the Group's business through the contractual arrangements with the VIEs. 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 the VIEs may not be as effective as direct ownership would be.

***Any failure by the VIEs or their respective shareholders to perform their obligations under our contractual arrangements with them would have a material and adverse effect on the Group's business.***

If any of the VIEs or their respective 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 the VIEs refuse to transfer their equity interest in the VIEs 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 the VIEs, 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 the VIEs and third parties were to impair the contractual arrangements that make us the primary beneficiary of the VIEs for accounting purposes, our ability to consolidate the financial results of the VIEs would be affected, which would in turn result in a material adverse effect on the Group's business, operations and financial condition.

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

The legal system in the PRC is evolving and the evolution of 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 laws. 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 considered as the primary beneficiary of the VIEs for accounting purposes, and the Group's ability to conduct business may be negatively affected.

***The shareholders of the VIEs may have actual or potential conflicts of interest with us, which may materially and adversely affect the Group's business and financial condition.***

The shareholders of the VIEs may have actual or potential conflicts of interest with us. These shareholders may refuse to sign or breach, or cause the VIEs to breach, or refuse to renew, the existing contractual arrangements we have with them and the VIEs, which would have a material and adverse effect on our ability to be considered as the primary beneficiary of the VIEs for accounting purposes and receive economic benefits from the VIEs. For example, the shareholders may be able to cause our agreements with the VIEs 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 the Group's business and subject us to substantial uncertainty as to the outcome of any such legal proceedings.

***Contractual arrangements in relation to the VIEs may be subject to scrutiny by the PRC tax authorities and they may determine that the Group owes additional taxes, which could negatively affect the Group's 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. The Group 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 the VIEs 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 the VIEs for PRC tax purposes, which could in turn increase 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 the VIEs for the adjusted but unpaid taxes according to the applicable regulations. The Group's financial position could be materially and adversely affected if the VIEs' 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 the VIEs, which could severely disrupt the Group's business, render the Group unable to conduct some or all of the business operations and constrain the Group's growth.***

As part of our contractual arrangements with the VIEs, the VIEs hold certain assets, licenses and permits that are material to their business operations, such as the ICP License and the License for the Production and Operation of Radio and Television Program. The contractual arrangements contain terms that specifically obligate VIEs' shareholders to ensure the valid existence of the VIEs and restrict the disposal of material assets of the VIEs. However, in the event the VIEs' shareholders breach the terms of these contractual arrangements and voluntarily liquidate the VIEs, or the VIEs declare 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 the Group's business operations or otherwise benefit from the assets held by the VIEs, which could have a material adverse effect on the Group's business, financial condition and results of operations. Furthermore, if the VIEs undergo a voluntary or involuntary liquidation proceeding, their shareholders or unrelated third-party creditors may claim rights to some or all of the assets of the VIEs, thereby hindering the Group's ability to operate business as well as constrain the Group's 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 65.7% of our voting power and Mr. Tongbo Liu, our director and our Chief Executive Officer, owns approximately 11.7% of our voting power as of the date of this annual report. In addition, Mr. Peng Ou, Mr. Tongbo Liu and certain of our senior management and employees collectively beneficially own approximately 8.2% of our issued and outstanding Class A ordinary shares and 96.2% of our issued and outstanding Class C ordinary shares, which constitute approximately 77.6% of the aggregate voting power of our total issued and outstanding share capital as of the date of this annual report. See "—Risks Related to the ADSs—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 the Group's 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 the ADSs.

**Risks Related to Doing Business in China**

***The approval, filing or other requirements of the China Securities Regulatory Commission or other PRC government authorities may be required under PRC law in connection with our issuance of securities overseas, and if required, we cannot predict whether or for how long the Group will be able to obtain such approval or complete such filing or other requirements.***

The Regulations on Mergers and Acquisitions of Domestic Enterprises by Foreign Investors, or the M&A Rules, purport to require offshore special purpose vehicles that are controlled by PRC companies or individuals and that acquire PRC domestic companies or assets by using such offshore special purpose vehicles' shares as a means of payment for the purpose of seeking a public listing on an overseas stock exchange, to obtain CSRC approval prior to publicly listing their

------

securities on an overseas stock exchange. The interpretation and application of the regulations remain unclear. If CSRC approval under the M&A Rules is required, it is uncertain whether it would be possible for the Group to obtain the approval, and any failure to obtain or delay in obtaining CSRC approval for our future issuance of securities overseas would subject the Group to sanctions imposed by the CSRC and other PRC regulatory agencies.

Furthermore, the Opinions on Strictly Cracking Down on Illegal Securities Activities emphasized the need to strengthen the administration over "illegal securities activities" and the supervision on overseas listings by China-based companies, and proposed to take effective measures, such as promoting the construction of relevant regulatory systems to deal with the risks and incidents faced by China-based overseas-listed companies, although such opinions did not specify the definition of "illegal securities activities." Such opinions further provided that the special provisions of the State Council on overseas offerings and listings by those companies limited by shares will be revised and therefore the duties of domestic industry competent authorities and regulatory agencies will be clarified.

On February 17, 2023, the CSRC released the Overseas Listing Trial Measures, and five supporting guidelines, effective on March 31, 2023. Pursuant to the Overseas Listing Trial Measures, domestic companies that seek to offer or list securities overseas, either in direct or indirect means, are required to report and file required documents with the CSRC. In addition, domestic companies that have been listed on a foreign stock exchange prior to the effective date of the Overseas Listing Trial Measures are required to file with the CSRC within three working days of the completion of fund raising activities on the same overseas capital market and shall make required filing immediately after they submit application for their listing or offering securities in other overseas capital markets. If a domestic company fails to complete the filing procedure or conceals any material fact or falsifies any major content in its filing documents, such domestic company may be subject to administrative penalties, such as order to rectify, warnings, fines, and its controlling shareholders, actual controllers, the person directly in charge and other directly liable persons may also be subject to administrative penalties, such as warnings and fines. See "Item 4. Information on the Company—4.B. Business Overview—Regulation—M&A Regulations and Overseas Listings." However, since the Overseas Listing Trial Measures was newly promulgated, the interpretation, application and enforcement of Overseas Listing Trial Measures remain unclear. We cannot assure you that we could complete the filing procedure in relation to any further capital raising activities as required in a timely manner, or at all. The CSRC or other PRC regulatory agencies also may take further actions requiring the Group, or making it advisable for the Group, not to proceed with such offering or maintain the listing status of the ADSs. If we proceed with any of such offering or maintain the listing status of the ADSs without obtaining the CSRC's approval to the extent it is required, or if the Group is unable to comply with any new approval or filing requirements which might be adopted for offerings that we have completed prior to the effective date of the Overseas Listing Trial Measures, the Group may face regulatory actions or other sanctions from the CSRC or other PRC regulatory agencies. These regulatory agencies may impose fines and penalties on the Group's operations in China, limit the Group's ability to pay dividends outside of China, limit the Group's operating privileges in China, delay or restrict the repatriation of the proceeds from offering of securities overseas into China or take other actions that could have a material adverse effect on the Group's business, financial condition, results of operations and prospects, as well as the trading price of the ADSs.

Furthermore, if there are any other approvals, filings and/or other administration procedures to be obtained from or completed with the CSRC or other PRC regulatory agencies as required by any new laws and regulations for any of our future proposed offering of securities overseas or the listing of the ADSs, we cannot assure you that the Group can obtain the required approval or complete the required filings or other regulatory procedures in a timely manner, or at all. Any failure to obtain the relevant approvals or complete the filings and other relevant regulatory procedures may subject the Group to regulatory actions or other sanctions from the CSRC or other PRC regulatory agencies, which may have a material adverse effect on the Group's business, financial condition or results of operations.

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

Substantially all of the Group's assets and operations are located in China. Accordingly, the Group's 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 government continues to play a significant role in regulating industry development by imposing industrial policies. The Chinese government also exercises significant regulation 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.

Meanwhile, economic conditions in China are sensitive to global economic conditions, changes in domestic economic and political policies and the expected or perceived overall economic growth rate in China. There have been concerns over the relationship among China and other Asian countries, which may result in or intensify potential conflicts in relation to territorial disputes. In recent years, there have also been ongoing concerns about the relationship and the trade disputes between the United States and China. These tensions have been marked by the imposition of higher tariffs and retaliatory measures from both sides, reflecting broader strategies to address perceived trade imbalances. While these developments have not directly impacted our business, prolonged trade disputes may disrupt global economic conditions, potentially impacting our business and growth prospects.

In addition, on October 28, 2024, the U.S. Department of the Treasury issued a final rule on outbound investment,

------

effective January 2, 2025, which restricts or requires notification of certain investments by U.S. persons in Chinese entities involved in semiconductors, quantum technologies, and artificial intelligence. Although we believe we are not currently subject to these restrictions, future developments in our business or changes in law may result in such designation, which may materially and adversely affect our ability to raise capital. On February 21, 2025, the United States President Donald Trump issued a National Security Presidential Memorandum titled the America First Investment Policy (the "America First Investment Policy") to provide guidance on investment oversight. The America First Investment Policy includes directives to, among other things, (i) determine if adequate financial auditing standards are upheld for companies covered by the HFCAA, and (ii) review the variable interest entity and subsidiary structures used by "foreign-adversary companies" to trade on United States exchanges, as well as allegations of fraudulent behavior by these companies, to protect United States investors. More recently, in May 2025, top Republican officers in the United States have asked SEC to consider whether Chinese companies listed on the U.S. stock exchange should be delisted for failing to protect U.S. investors. We face risks of losing deposits in the event of the closure or systematic failures of banks and if banks or financial institutions close or fail due to issues such as bankruptcy, fraud, or insolvency. These failures can destabilize the financial system and harm the wider economy as a whole. It is unclear whether these challenges and uncertainties will be addressed or resolved, and how they might impact global political and economic conditions over the long term.

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 the Group's business and operating results, lead to a reduction in demand for the Group's services and adversely affect the Group's 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, the Group's financial condition and results of operations may be adversely affected by government regulation over capital investments or changes in tax regulations. In addition, in the past the Chinese government has implemented certain measures, including interest rate adjustment. It is uncertain whether these measures would cause decreased economic activity in China, which may adversely affect the Group's business and operating results.

***Evolution of the PRC legal system, including changes in policies, laws and regulations in China, could adversely affect the Group. The enforcement of laws and rules and regulations in China may change quickly, which could result in a material adverse change in the Group's operations and the value of the ADSs.***

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, the PRC legal system continues to evolve rapidly, 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 and may change quickly with short notice, which could result in a material adverse change in the Group's operations and the value of the ADSs. Since PRC administrative and court authorities have 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 the Group enjoys. These uncertainties may affect the Group's judgment on the relevance of legal requirements and the Group's ability to enforce 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 the Group.

However, as there are still regulatory uncertainties in this regard, we cannot assure you that the Group will be able to comply with new laws and regulations in all respects in a timely manner, and the Group may be ordered to rectify, suspend or terminate any actions or services that are deemed illegal by the regulatory authorities and become subject to material penalties, which may materially harm the Group's business, financial condition, results of operations and prospects.

Furthermore, the PRC legal system is based in part on government policies and rules, some of which are not published on a timely basis or are published with short notice. As a result, we may not be aware of the Group's violation of any of these policies and rules until sometime after the violation. In addition, administrative and court proceedings may be protracted, resulting in substantial costs and diversion of resources and management attention.

***The PRC government's significant oversight over the Group's business operation in China could result in a material adverse change in the Group's operations in China and the value of the ADSs. The Chinese government may intervene or influence the Group's operations in China at any time, or may exert more regulation over offerings conducted overseas and/or foreign investment in China-based issuers. Any actions by the Chinese government to exert more oversight and regulation over offerings that are conducted overseas and/or foreign investment in China-based issuers could significantly limit or completely hinder our ability to offer or continue to offer securities to investors and cause the value of such securities to significantly decline or become worthless.***

The PRC government has significant oversight and discretion over the conduct of the Group's business and may

------

intervene with or influence the Group's operations as the government deems appropriate to further regulatory, political and societal goals. The PRC government has recently published new policies that adversely affected educational industry, especially the educational services related to K-12 students, and we cannot rule out the possibility whether it will in the future further release regulations or policies regarding educational industry that could further adversely affect the Group's business, financial condition and results of operations. Furthermore, the PRC government has also recently indicated an intent to exert more oversight and regulation over securities offerings and other capital markets activities that are conducted overseas and foreign investment in China-based issuers like us. For details, see "Item 3. Key Information—D. Risk Factors—Risks Related to Doing Business in China—Evolution of the PRC legal system, including changes in policies, laws and regulations in China, could adversely affect the Group. The enforcement of laws and rules and regulations in China may change quickly, which could result in a material adverse change in the Group's operations and the value of the ADSs." Any such action, once taken by the PRC government, could significantly limit or completely hinder our ability to offer or continue to offer securities to investors and cause the value of such securities to significantly decline or in extreme cases, become worthless.

***You may experience difficulties in effecting service of legal process, enforcing foreign judgments or bringing actions in China, including Hong Kong, against the Group or the Group's management named in the annual report based on foreign laws.***

We are a Cayman Islands exempted company and currently substantially all of the Group's business operations are conducted in the PRC through our subsidiaries incorporated in the PRC and the contractual arrangements among our PRC subsidiaries and the VIEs. Substantially all of the Group's assets are located in China. In addition, all our directors and senior executive officers reside within China for a significant portion of the time and most are PRC nationals, while two of our directors are Hong Kong residents. The Group does not have any material operations or assets in Hong Kong. It may be difficult for our shareholders to effect service of process upon the Group or those persons inside China, including Hong Kong. In addition, neither China nor Hong Kong has 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 or Hong Kong 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 and Hong Kong subsidiaries to fund any cash and financing requirements we may have, and any limitation on the ability of these subsidiaries in the PRC, including Hong Kong, to make payments to us could have a material and adverse effect on our ability to conduct the Group's business.***

We are a Cayman Islands holding company and we rely principally on dividends and other distributions on equity from our PRC and Hong Kong subsidiaries for our cash requirements, including for services of any debt we may incur. To the extent cash in the business is in the PRC, including Hong Kong, or a PRC (including Hong Kong) entity, the funds may not be available to fund operations or for other use outside of the PRC or Hong Kong due to interventions in or the imposition of restrictions and limitations by the PRC government to transfer cash from a PRC entity to the use outside the PRC. Our subsidiaries are permitted to pay dividends to their shareholders, and eventually to Sunlands Technology Group, only out of their retained earnings, if any, as determined in accordance with the applicable accounting standards and regulations. Such payment of dividends by entities registered in China, including Hong Kong, is subject to limitations, which could result in limitations on the availability of cash to fund dividends or make distributions to holders of our securities. For example, our PRC subsidiaries and the VIEs are required to make appropriations to certain statutory reserve funds or may make appropriations to certain discretionary funds, which are not distributable as cash dividends except in the event of a solvent liquidation of the companies.

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, the VIEs and their respective 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. 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 the Group's businesses, pay dividends or otherwise fund and conduct the Group's business.

To address the persistent capital outflow and the depreciation of Renminbi against U.S. dollars in the fourth quarter of 2016, the People's Bank of China and the State Administration of Foreign Exchange, or SAFE, implemented a series of capital regulation measures in the subsequent months, including stricter vetting procedures for China-based companies to remit foreign currency for overseas acquisitions, dividend payments and shareholder loan repayments. For instance, the Circular on Promoting the Reform of Foreign Exchange Management and Improving Authenticity and Compliance Review, or the SAFE Circular 3, issued on January 26, 2017, provides that the banks shall, when dealing with dividend remittance transactions from domestic enterprise to its offshore shareholders of more than US$50,000, review the relevant

------

board resolutions, original tax filing form and audited financial statements of such domestic enterprise based on the principal of genuine transaction. It is uncertain whether the PRC government would continue to strengthen its capital regulation and our PRC subsidiaries' dividends and whether other distributions would be subject to tightened scrutiny in the future. Any limitation on the ability of our PRC subsidiaries to pay dividends or make other distributions to us could materially and adversely limit our ability to grow, make investments or acquisitions that could be beneficial to the Group's business, pay dividends, or otherwise fund and conduct the Group's 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.

For details about the applicable regulations and rules relating to such cash transfers through our Group, see "Item 3. Key Information—Restrictions on Foreign Exchange and the Ability to Transfer Cash between Entities, Across Borders and to U.S. Investors." and "—Governmental regulation of currency conversion may limit the Group's ability to utilize the Group's net revenues effectively and affect the value of your investment."

***The custodians or authorized users of the Group's 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 the Group's chops and seals, the Group has 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 the Group's office automation system and the application will be verified and approved by authorized employees in accordance with the Group's internal control procedures and rules. In addition, in order to maintain the physical security of the Group's chops, the Group generally has them stored in secured locations accessible only to authorized employees. Although the Group monitors such authorized employees, the procedures may not be sufficient to prevent all instances of abuse or negligence. There is a risk that the Group's employees could abuse their authority, for example, by entering into a contract not approved by the Group or seeking to gain control of one of the Group's subsidiaries or the VIEs. If any employee obtains, misuses or misappropriates the Group's chops and seals or other controlling non-tangible assets for whatever reason, the Group could experience disruption to the Group's normal business operations. The Group may have to take corporate or legal action, which could involve significant time and resources to resolve and divert management from the Group's operations.

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

The value of Renminbi against U.S. dollars 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 governments of the PRC, the United States or other countries. On July 21, 2005, the PRC government changed its policy of pegging the value of Renminbi to U.S. dollars. Following the removal of the U.S. dollar peg, Renminbi appreciated more than 20% against U.S. dollars over the following three years. Since June 2010, Renminbi has started to appreciate slowly against U.S. dollars, though there have been periods when U.S. dollars has appreciated against Renminbi. On August 11, 2015, the PBOC allowed Renminbi to depreciate by approximately 2% against U.S. dollars. Since then and until the end of 2016, Renminbi has depreciated against U.S. dollars by approximately 10%. It is difficult to predict how long such depreciation of Renminbi against U.S. dollars may last and when and how the relationship between Renminbi and U.S. dollars may change again.

All of the Group's revenue and substantially all of the Group's 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 the Group's 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 the initial public offering into Renminbi for our operations, appreciation of Renminbi against U.S. dollars would have an adverse effect on 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 U.S. dollars against Renminbi would have a negative effect on the amount of U.S. dollars.

***Governmental regulation of currency conversion may limit the Group's ability to utilize the Group's net revenues effectively and affect the value of your investment.***

The PRC government imposes regulation on the convertibility of the Renminbi into foreign currencies and, in certain cases, the remittance of currency out of China. The Group receives substantially all revenues in Renminbi. Under the Group's 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 the VIEs 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 regulation system prevents the Group from obtaining sufficient foreign currencies to satisfy the Group's foreign currency demands, we may not be able to pay dividends in foreign currencies to our shareholders, including holders of the ADSs.

***Certain PRC regulations may make it more difficult for the Group 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 and recently amended in 2024, are triggered. Moreover, the Anti-Monopoly Law promulgated by the Standing Committee of the National People's Congress which became effective in 2008 and was amended in June 2022, requires that transactions which are deemed concentrations and involve parties with specified turnover thresholds must be cleared by the relevant governmental authorities before they can be completed. On February 7, 2021, the Anti-monopoly Commission of the State Council, published the Anti-Monopoly Guidelines for the Internet Platform Economy Sector that aims at specifying some of the circumstances under which an activity of internet platforms may be identified as monopolistic act as well as setting out merger controlling filing procedures involving variable interest entities. 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. The Measures for the Security Review of Foreign Investments promulgated by the National Development and Reform Commission and MOFCOM which became effective from January 2021 further requires that security review by relevant governmental authorities shall be conducted in accordance with the provisions of the Measures for foreign investments that affect or may affect national security. The Group may pursue potential strategic acquisitions that are complementary to the Group's 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 the Group's ability to complete such transactions, which could affect the Group's ability to expand the Group's business or maintain the Group's market share.

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

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. SAFE Notice 13 further provides that annual inspection of inbound foreign direct investments and outbound overseas direct investments is canceled. Instead, relevant entities or individuals, as the case may be, shall register data and information with respect to their inbound foreign direct investments and outbound overseas direct investment interests with SAFE.

We have requested our shareholders that we are aware of being subject to SAFE regulations to make all necessary registrations, filings and amendments with the local SAFE branch or qualified banks as required by SAFE Circular 37. We cannot assure you, however, that all of these individuals may continue to make required registrations, 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 the Group 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, the Group's 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, the Group 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 the Group's 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 the Group's business and prospects.

***Any failure to comply with PRC regulations regarding the registration requirements for employee stock incentive plans may subject the PRC plan participants or the Group 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 because we are an overseas-listed company. 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 "Item 4. Information on the Company—4.B. Business Overview—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 the Group 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 are required to withhold a 10% withholding tax from dividends we pay to our shareholders that are non-resident enterprises, including the holders of the ADSs. In addition, non-resident enterprise shareholders (including the ADS holders) may be subject to PRC tax on gains realized on the sale or other disposition of ADSs or ordinary shares, if such income is treated as sourced from within the PRC. Furthermore, if we are deemed a PRC resident enterprise, dividends paid to our non-PRC individual shareholders (including the ADS holders) and any gain realized on the transfer of 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 the Group's financial condition and results of operations.

***Uncertainties exist with respect to the interpretation and implementation of the newly enacted Foreign Investment Law and how it may impact the Group's business, financial condition and results of operations.***

On March 15, 2019, the National People's Congress promulgated the Foreign Investment Law, which came into effect on January 1, 2020 and replaced the trio of existing laws regulating foreign investment in China, namely, the Sino-foreign Equity Joint Venture Enterprise Law, the Sino-foreign Cooperative Joint Venture Enterprise Law and the Wholly Foreign-invested Enterprise Law, together with their implementation rules and ancillary regulations. The Foreign Investment Law embodies an expected PRC regulatory trend to rationalize its foreign investment regulatory regime in line with prevailing international practice and the legislative efforts to unify the corporate legal requirements for both foreign and domestic investments. The enacted Foreign Investment Law does not touch upon the relevant concepts and regulatory regimes of "actual control" in determining whether a company is considered a foreign invested enterprise, and thus this regulatory

------

topic remains unclear under the Foreign Investment Law. On December 26, 2019, the State Council published the Implementation Rules of Foreign Investment Law, which came into effect on January 1, 2020. The Implementation Rules of Foreign Investment Law restates certain principles of the Foreign Investment Law. However, since the Foreign Investment Law and the Implementation Rules of Foreign Investment Law are relatively new, uncertainties still exist in relation to its interpretation and implementation. For instance, though the Foreign Investment Law does not explicitly classify contractual arrangements as a form of foreign investment, it contains a catch-all provision under the definition of "foreign investment," which includes investments made by foreign investors in China through means stipulated in laws or administrative regulations or other methods prescribed by the State Council. Therefore, it still leaves leeway for future laws, administrative regulations or provisions promulgated by the State Council to provide for contractual arrangements as a form of foreign investment. Furthermore, if future laws, administrative regulations or provisions prescribed by the State Council mandate further actions to be taken by companies with respect to existing contractual arrangements, such as unwinding the Group's existing contractual arrangements and/or disposal of the Group's related business operations, the Group may face uncertainties as to whether the Group can complete such actions in a timely manner, or at all. Failure to take timely and appropriate measures to cope with any of these or similar regulatory compliance challenges could materially and adversely affect the Group's current corporate structure, financial condition and business operations.

***The PCAOB had previously been unable to inspect our auditor in relation to their audit work performed for the Group's financial statements, and any future inability to do so would deprive investors of the benefits of such inspections.***

Our auditor, the independent registered public accounting firm that issues the audit report included elsewhere in this annual report, as an auditor of companies that are traded publicly in the United States and a firm registered with the Public Company Accounting Oversight Board (United States), or the PCAOB, is subject to laws in the United States pursuant to which the PCAOB conducts regular inspections to assess its compliance with the applicable professional standards. Since our auditor is located in mainland China, a jurisdiction where the PCAOB had been unable to conduct inspections without the approval of the Chinese authorities until 2022, our auditor was historically uninspected by the PCAOB.

On August 26, 2022, the PCAOB signed a Statement of Protocol with the China Securities Regulatory Commission and the Ministry of Finance of the People's Republic of China governing inspections and investigations of audit firms based in China, which marks the first step toward providing access for the PCAOB to inspect and investigate registered public accounting firms headquartered in Mainland China and Hong Kong. On December 15, 2022, the PCAOB announced that it was able to conduct inspections and investigations completely of PCAOB-registered public accounting firms headquartered in mainland China and Hong Kong in 2022, and vacated its previous 2021 Determinations accordingly. This marks the first time that Chinese authorities allowed access for complete inspections and investigations meeting U.S. standards, as required under the Sarbanes-Oxley Act.

Notwithstanding the foregoing, the past lack of the PCAOB inspections in mainland China prevented the PCAOB from fully evaluating audits and quality control procedures of our independent registered public accounting firm, which made it more difficult to evaluate the effectiveness of our independent registered public accounting firm's audit procedures or quality control procedures as compared to auditors outside of mainland China that were subject to the PCAOB inspections. Any future lack of the PCAOB inspections in mainland China would prevent the PCAOB from fully evaluating audits and quality control procedures of our auditor, as a result of which the Group and investors will be deprived of the benefits of such PCAOB inspections, which could cause investors to lose confidence in our audit procedures and the quality of the Group's financial statements.

***The ADSs will be delisted and the ADSs and shares will be prohibited from trading in the United States under the Holding Foreign Companies Accountable Act, or the HFCAA, if the PCAOB is unable to inspect or investigate completely auditors located in China for two consecutive years.***

The HFCAA was signed into law on December 18, 2020. Under the HFCAA, as amended by the Consolidated Appropriations Act of 2023, if the SEC determines that we have filed audit reports issued by a registered public accounting firm that has not been subject to complete PCAOB inspection or investigation for two consecutive years, the SEC shall prohibit our ADSs from being traded on a national securities exchange or in the over-the-counter trading market in the United States.

On December 2, 2021, the SEC adopted final amendments implementing the HFCAA, which include requirements to disclose the auditor's name and location, the percentage of shares owned by governmental entities, whether any governmental entity has a controlling financial interest in the issuer, the name of each Chinese Communist Party official who is a member of the issuer's board of directors, and whether the issuer's articles of incorporation contain any charter of the Chinese Communist Party.

On December 16, 2021, the PCAOB issued a determination that it was unable to inspect or investigate completely registered public accounting firms headquartered in mainland China and Hong Kong. We were consequently identified as a Commission-identified issuer under the HFCAA. On December 15, 2022, the PCAOB vacated that determination after securing complete access to inspect and investigate registered public accounting firms headquartered in mainland China and Hong Kong for the first time in history. As a result, we were removed from the Commission-identified issuer list and

------

are not currently at risk of a trading prohibition under the HFCAA. As of the date of this annual report, there are no PCAOB determinations in effect with respect to auditors headquartered in mainland China or Hong Kong.

Notwithstanding the foregoing, the PCAOB conducts annual assessments of whether it continues to have complete access. Should PRC authorities obstruct or otherwise fail to facilitate the PCAOB's access at any point in the future, the PCAOB may immediately consider issuing a new determination, which could result in our being re-identified as a Commission-identified issuer and, if the determination remains in effect for two consecutive years, subject our ADSs to a trading prohibition under the HFCAA. Whether complete access will be maintained is subject to uncertainty and depends on factors outside our and our auditor's control, including the state of U.S.-China relations and the continued cooperation of PRC regulatory authorities.The current geopolitical environment introduces additional dimensions of risk. Escalating trade tensions between the United States and China, including sweeping tariff measures and technology-sector restrictions imposed in 2025, have materially increased bilateral regulatory uncertainty. Separately, proposals under consideration in the U.S. Congress in 2025 to dissolve the PCAOB and transfer its functions to the SEC, if enacted, could undermine the existing inspection framework: the PCAOB's status as a non-governmental entity was integral to China's agreement to the 2022 inspection arrangement, and it is uncertain whether PRC authorities would extend the same cooperation to a direct U.S. government agency. Any such structural change, or any deterioration in U.S.-China relations that leads PRC authorities to restrict PCAOB access, could result in our being re-identified as a Commission-identified issuer and, if that determination remains in effect for two consecutive years, subject our ADSs to a trading prohibition under the HFCAA.

Any prohibition on trading in our ADSs would substantially impair shareholders' ability to buy or sell the ADSs, adversely affect the price of the ADSs, significantly impair our ability to raise capital on acceptable terms, and have a material adverse effect on our business, financial condition and prospects. There is no certainty that we would be able to list the ADSs on a non-U.S. exchange or develop an alternative trading market for our shares outside the United States on a timely basis or at all.

***Regulation and censorship of information disseminated over the internet in China may adversely affect the Group's business and reputation and subject the Group 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 the Group's website is found to be in violation of any such requirements, the Group may be penalized by relevant authorities, and the Group's operations or reputation could be adversely affected.

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

Shareholder claims or regulatory investigation that are common in the United States generally are difficult to pursue as a matter of law or practicality in China. For example, in China, there are significant legal and other obstacles to providing information needed for regulatory investigations or litigation initiated outside China. Although the authorities in China may establish a regulatory cooperation mechanism with the securities regulatory authorities of another country or region to implement cross-border supervision and administration, such cooperation with the securities regulatory authorities in the Unities States may not be efficient in the absence of mutual and practical cooperation mechanism. Furthermore, Article 177 of the PRC Securities Law, or Article 177, which became effective in March 2020, prohibits, without the approval of the securities regulatory authority in China, (i) foreign securities regulators from engaging in any inspection activities within China and (ii) anyone from providing any documents or materials relating to capital markets activities to foreign parties. While detailed interpretation of or implementation rules under Article 177 have yet to be promulgated, the inability for an overseas securities regulator to directly conduct investigation or evidence collection activities within China may further increase difficulties faced by you in protecting your interests. In addition, the Overseas Listing Trial Measures provides, among others, that domestic companies or individuals shall obtain the consent from the CSRC and relevant competent departments, if they provide relevant documents and materials in accordance with the requirements of overseas securities regulators for investigation and collection of evidence. However, since the Overseas Listing Trial Measures was newly promulgated, the interpretation, application and enforcement of Overseas Listing Trial Measures remain unclear. If the Group is required to obtain the consent from the CSRC and relevant competent departments when providing information needed for regulatory investigations or litigation initiated outside China, it is uncertain whether the Group could obtain such consent in a timely manner, or at all.

**Risks Related to the ADSs** 

***If the market price for the ADSs falls below US$1.00 for an extended period of time, or falls to US$0.16 at any time, the*** 

------

***ADSs may be delisted from the NYSE.***

Pursuant to NYSE Rule 802.01C, a company will be considered to be below compliance standards if the average closing price of a security as reported on the consolidated tape is less than US$1.00 over a consecutive 30 trading-day period. Once notified, the company must bring its share price and average share price back above US$1.00 within the applicable cure period following receipt of the notification. The company can regain compliance at any time during the cure period if on the last trading day of any calendar month during the cure period the company has a closing share price of at least US$1.00 and an average closing share price of at least US$1.00 over the 30 trading-day period ending on the last trading day of that month. In the event that at the expiration of the cure period, both a US$1.00 closing share price on the last trading day of the cure period and a US$1.00 average closing share price over the 30 trading-day period ending on the last trading day of the cure period are not attained, the NYSE will commence suspension and delisting procedures. In addition, we understand that the NYSE has a policy to suspend trading immediately and commence delisting procedures if the market price of securities falls to US$0.16 or less. We received a letter from the NYSE dated July 23, 2021 notifying us that the stock prices of the ADSs are below compliance standards due to the fact that the average closing price of the ADSs was less than $1.00 for a consecutive 30 trading-day period. In response to the letter from the NYSE, we changed the ratio of the ADSs representing our Class A ordinary shares from each 25 ADSs representing one Class A ordinary share to each two ADSs representing one Class A ordinary share, effective August 31, 2021. However, we cannot assure you that the ADSs will remain in compliance with the NYSE listing rules going forward. If the ADSs are delisted from the NYSE, the liquidity and value of an investment in the ADSs will be materially and adversely affected.

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

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

&nbsp;&nbsp;&nbsp;&nbsp;•variations in our revenues, earnings and cash flows;

&nbsp;&nbsp;&nbsp;&nbsp;•announcements of new investments, acquisitions, strategic partnerships or joint ventures by the Group or our competitors;

&nbsp;&nbsp;&nbsp;&nbsp;•announcements of new offerings, solutions and expansions by the Group or our competitors;

&nbsp;&nbsp;&nbsp;&nbsp;•changes in financial estimates by securities analysts;

&nbsp;&nbsp;&nbsp;&nbsp;•detrimental adverse publicity about the Group, the Group's services or the Group's industry;

&nbsp;&nbsp;&nbsp;&nbsp;•announcements of new regulations, rules or policies relevant for the Group's business;

&nbsp;&nbsp;&nbsp;&nbsp;•additions or departures of key personnel;

&nbsp;&nbsp;&nbsp;&nbsp;•release of lockup or other transfer restrictions on our outstanding equity securities or sales of additional equity securities;

&nbsp;&nbsp;&nbsp;&nbsp;•potential litigation or regulatory investigations;

&nbsp;&nbsp;&nbsp;&nbsp;•allegations of a lack of effective internal control over financial reporting resulting in financial; inadequate corporate governance policies, or allegations of fraud, among other things, involving China-based issuers; and

&nbsp;&nbsp;&nbsp;&nbsp;•any of these factors may result in large and sudden changes in the volume and price at which the ADSs will trade.

In the past, shareholders of public companies have often brought securities class action suits against those companies following periods of instability in the market price of their securities. If we were involved in a class action suit, it could divert a significant amount of management's attention and other resources from the Group's business and operations and require the Group to incur significant expenses to defend the suit, which could harm the Group's results of operations. Any such class action suit, whether or not successful, could harm the Group's 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 the Group's financial condition and results of operations.

***If securities or industry analysts do not publish research or reports about the Group's 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 the Group's business. If one or more analysts who cover the Group downgrade the ADSs, the market price for the ADSs would likely decline. If one or more of these analysts cease to cover the Group or fail to regularly publish reports on the Group, 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, 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. 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.

***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 enforcement actions by the SEC or other U.S. authorities.

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 the Group's business. Even if such allegations are ultimately proven to be groundless, allegations against the Group could severely impact the Group's 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, 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 to fund the development and growth of the Group's 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. Under Cayman Islands law, a Cayman Islands exempted 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 the Group from our subsidiaries, the Group's 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 price appreciation of the ADSs. There is no guarantee that the ADSs will appreciate in value or even maintain the price at which you purchased the ADSs. You may not realize a return on your investment in the ADSs and you may even lose your entire investment in 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 with limited liability incorporated under the laws of the Cayman Islands. Our corporate affairs are governed by our memorandum and articles of association, as amended from time to time, the Companies Act (As Revised) of the Cayman Islands and the common law of the Cayman Islands. The rights of shareholders to take action against our directors, actions by our minority shareholders and the fiduciary duties of our directors to the Group under Cayman Islands law are to a large extent governed by the common law of the Cayman Islands. The common law of the Cayman Islands is derived in part from comparatively limited judicial precedent in the Cayman Islands as well as from the common law of England, the decisions of whose courts are of persuasive authority, but are not binding, on a court in the Cayman Islands. The rights of our shareholders and the fiduciary duties of our directors under Cayman Islands law are not as clearly established as they would be under statutes or judicial precedent in some jurisdictions in the United States. In particular, the Cayman Islands has a less developed body of securities laws than the United States. Some U.S. states, such as Delaware, have more fully developed and judicially interpreted bodies of corporate law than the Cayman Islands. In

------

addition, Cayman Islands companies may not have 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 or obtain copies of register of members or corporate records (other than copies of the memorandum and articles of association, the register of mortgages and charges, and any special resolutions passed by the shareholders) of these companies. The Registrar of Companies of the Cayman Islands shall make available the list of the names of the current directors of the Company (and where applicable the current alternate directors of the Company) for inspection by any person upon payment of a fee by such person. Our directors have discretion under our articles of association 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.

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

We are a Cayman Islands exempted company and substantially all of our assets are located outside of the United States. Substantially all of the Group's 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.

***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 the ADSs.***

Holders of ADSs do not have the same rights as our registered shareholders. As a holder of the ADSs, you will not have any direct right to attend general meetings of our shareholders or to cast any votes at such meetings. You will only be able to exercise the voting rights which attach to the underlying Class A ordinary shares represented by 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 underlying Class A ordinary shares represented by your ADSs. Upon receipt of your voting instructions, the depositary may try to vote the underlying Class A ordinary shares represented by 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 sufficient advance notice of the meeting to enable you to withdraw the underlying Class A ordinary shares represented by 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, 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 underlying Class A ordinary shares represented by your ADSs are voted and you may have no legal remedy if the underlying Class A ordinary shares represented by 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 triple-class share structure such that our ordinary shares consist of Class A ordinary shares, Class

------

B ordinary shares and Class C ordinary shares. 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.

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 current and prior senior management and employees collectively beneficially own all of our issued and outstanding Class C ordinary shares. These Class C ordinary shares constitute approximately 49.8% of our total issued and outstanding share capital and 80.0% of the aggregate voting power of our total issued and outstanding share capital as of the date of this annual report. PV PLUTO LIMITED, an entity wholly owned and controlled by Primavera Capital Fund, beneficially owns all of our issued and outstanding Class B ordinary shares, which constitutes approximately 12.3% of our total issued and outstanding share capital and 13.9% of the aggregate voting power of our total issued and outstanding share capital as of the date of this annual report.

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 the Group's 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 the Group 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 the ADSs. This concentrated control will limit your ability to influence corporate matters and could discourage others from pursuing any potential merger, takeover or other change of control transactions that holders of Class A ordinary shares and ADSs may view as beneficial.

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

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

***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 the ADSs generally when our share register or the books of the depositary are closed, or at any time if we or the depositary thinks it is advisable to do so because of any requirement of law or of any government or governmental body, or under any provision of the deposit agreement, or for any other reason.

***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:

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

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

&nbsp;&nbsp;&nbsp;&nbsp;•the selective disclosure rules by issuers of material nonpublic information under Regulation FD

We are 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 are 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 an exempted 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 exempted 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 have followed and intend to continue 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.

***We believe that we likely were a passive foreign investment company, or PFIC, for U.S. federal income tax purposes for our 2025 taxable year, and that there is a risk that we may be a PFIC for the current and possibly future taxable years, 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. Passive income generally includes dividends, interest, rents, royalties and investment gains. Cash is a passive asset for these purposes. Goodwill and other intangible assets are active assets under the PFIC rules to the extent attributable to activities that produce active income.

The determination of our PFIC status is subject to certain uncertainties and is made by applying principles and methodologies that are in some circumstances unclear.

Based on the composition of our income and assets and the value of our assets, including goodwill and other intangible assets, which is based on the market price of the ADSs, we believe that we were likely a PFIC for the 2025 taxable year. In addition, it is not entirely clear how the contractual arrangements between our wholly-owned PRC subsidiaries, our consolidated affiliated entities and the shareholders of our consolidated affiliated entities will be treated for purposes of the PFIC rules. Because the treatment of the contractual arrangements is not entirely clear, because we hold a substantial amount of cash and because our PFIC status for any taxable year will depend on the composition of our income and assets and the value of our assets from time to time (which may be determined, in part, by reference to the market price of the ADSs or ordinary shares, which has been, and may continue to be, volatile), there is a risk that we may be a PFIC for our current taxable year and possibly future taxable years. If we are or 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 "Item 10. Additional Information—10.E. Taxation—Material U.S. Federal Income Tax Considerations—Passive Foreign Investment Company Rules."

Currently, substantially all of the Group's business operations are conducted in the PRC through our subsidiaries incorporated in the PRC, and the contractual arrangements among our PRC subsidiaries and the VIEs. Our wholly-owned PRC subsidiaries would enter into a series of contractual arrangements, including the Exclusive Technical Consultation and Service Agreement, the Business Operation Agreement, the Equity Interest Pledge Agreement, the Option Agreement, and Powers of Attorney, with the VIEs, their shareholders, and, where applicable, their operating subsidiaries (the "VIE Contractual Arrangements"). The VIE Contractual Arrangements allow us to (i) direct the activities of the VIEs that most significantly impact the VIEs' economic performance, (ii) receive substantially all of the economic benefits of the VIEs, and (iii) have an exclusive option to purchase all or part of the equity interests in the VIEs when and to the extent permitted by PRC law. As a result, we are considered the primary beneficiary of the VIEs for accounting purposes and are able to consolidate their operating results in the Group's financial statements under U.S. GAAP.

In December 2013, we entered into the VIE Contractual Arrangements with Beijing Shangde Jiaxun Education Technology Co., Ltd., or Sunlands Jiaxun, and its shareholders and operating subsidiaries, including the predecessor of Beijing Yuanchilaxiang Education Technology Co., Ltd (formerly known as "Beijing Shangde Online Education Technology Co., Ltd."), or Beijing Sunlands, a limited liability company through which we currently conduct business in the PRC.

*Interest, professional skills and professional certification preparation courses*

The Group develops interest and professional skills courses that help students cater to their interests and develop professional skills as the Group saw a surging trend in adults undertaking such courses online. As of December 31, 2025, the Group offered professional skills and interest courses such as Wealth Management, Voice Acting, Chinese Painting and Calligraphy. In addition, the Group also offers professional certification preparation courses designed to give students the skills, knowledge and abilities that are commonly required or helpful for a broad range of professions. The employment market is becoming increasingly competitive, motivating workers to enhance their career competitiveness through vocational education. As of December 31, 2025, the professional certification preparation courses covered various industries and professions, including Accounting, Human Resources and Teaching. The Group's solid foundation and rich resources in course portfolio has enabled the Group to successfully grasp market opportunities and effectively scale up the Group's offerings.

In recent years, the Group's course offerings have become more diversified, and the interest, professional skills and professional certification preparation course offerings have contributed to an increasing proportion of the Group's overall revenues. In 2023, 2024 and 2025, the interest, professional skills and professional certification preparation courses represented approximately 67.1%, 75.3% and 74.2%, respectively, of the Group's net revenues, and approximately 98.4%, 99.1% and 99.9%, respectively, of the Group's gross billings. In addition, the interest, professional skills and professional certification preparation courses represented approximately 95.0%, 97.6% and 98.1%, respectively, of the Group's new student enrollments in 2023, 2024 and 2025. See also "Item 3. Key Information—3.D. Risk Factors—Risks Related to the Group's Business—To the extent the Group relies on certain types of course offerings to generate revenues, the Group will be subject to concentration risks, including risks resulting from changes in government policies."

------

In addition to the course offerings discussed above, the Group also offers exam preparation "crash courses" for exam-taking students. Instead of covering a wide range of topics in a particular subject matter, these courses are meant to cover the most frequently tested areas in the exams and provide training on test-taking strategies and skills to help students improve their performance in actual exams.

*Degree- or diploma-oriented post-secondary courses*

The degree- or diploma-oriented post-secondary course offerings primarily consist of preparation courses for the STE, a state-administered exam in China for learners pursuing associate diplomas or bachelor's degrees, and other degree- or diploma-oriented post-secondary courses. As of December 31, 2025, STE courses covered 11 majors, including Administrative Management, Chinese Language and Literature, Accounting, Business Management, Human Resource Management, Law, Public Administration, Computer Information Management, Pre-School Education, Marketing and English. Other degree- or diploma-oriented post-secondary course offerings include preparation courses for the entrance examinations of Master of Business Administration ("MBA") in China and overseas.

Degree- or diploma-oriented post-secondary courses, especially STE courses, have historically accounted for the largest proportion of the Group's net revenues, gross billings and new student enrollments. In recent years, the Group's course offerings have become more diversified. In 2023, 2024 and 2025, degree- or diploma-oriented post-secondary courses represented approximately 24.8%, 10.3% and 13.5%, respectively, of the Group's net revenues, and approximately 1.6%, 0.9% and 0.1%, respectively, of the Group's gross billings. In addition, degree- or diploma-oriented post-secondary courses represented approximately 5.0%, 2.4% and 1.9%, respectively, of the Group's new student enrollments for the years ended December 31, 2023, 2024 and 2025.

***Interactive Learning Process***

*Live streaming course delivery*

The Group's teachers deliver courses in a live streaming format through the Group's websites and mobile application. We believe that the Group is one of the first to offer live streaming courses in China's education industry.

The Group's live streaming course delivery format allows the Group to cost-effectively expand student enrollments and maintain high teaching quality. Live streaming also improves efficiency of instruction and enriches the learning experience in a number of ways:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*Time efficiency and no geographic limitations*. While classroom-based students are often required to spend time commuting, the Group's live streaming learning format allows them to attend courses anytime, anywhere as long as there is Internet.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*High level of engagement and interaction*. The live streaming application (through support functions and plug-ins) allow students to engage in real-time Q&A with the faculty and their fellow students through live chats, which fosters an engaging and interactive learning setting. The live streaming application has a "tipping" function that allows students to "tip" the teacher with virtual gifts if they like the course, which improves student engagement and student-teacher interaction.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*Greater learning flexibility*. Every live class is recorded and made available to students enrolled in the course throughout their enrollment period, which allows them to attend courses at their convenience. This scheduling flexibility appeals to adult students with full-time jobs. The replay function allows students to learn at their own pace.

We believe the live streaming format and highly interactive learning experience makes the Group's services highly attractive to students. In 2023, 2024 and 2025, the Group's new student enrollments were 616,341, 674,649 and 579,788, respectively.

*Virtual learning community*

The Group strives to build a vibrant and highly interactive virtual community for students and faculty to augment their learning and teaching experience. For example, the Group has a bulletin board forum, available through the Group's website and mobile application that enables students in real time to share their ideas and learning experience with, as well as pose questions and answers to fellow students and the Group's faculty. This also provides a stimulating learning platform for students to socialize and interact with an extended network of fellow students and faculty members and to forge beneficial relationships. In addition, students can authorize his or her fellow students to view their learning progress and milestones, thus fostering an engaging and friendly competitive environment.

We believe a highly interactive virtual student community drives the existing students' level of engagement and significantly enhances the Group's attractiveness to prospective students.

***Community-Oriented Class Setup***

------

The Group's classes are set up to cultivate an interactive learning environment. The Group is committed to developing a sense of community among students and faculty, which we believe is critical to improving results.

Furthermore, the Group's community-oriented learning environment, coupled with the student-centric faculty structure, enable the Group to provide our students attention and support beyond class hours at a time and in a manner that is convenient to them, which further drives student engagement, customer loyalty and course consumption.

The Group's class is set up by schools, divisions and classes. Students are assigned to different schools and divisions based on the major and number of students enrolled for a given academic period. Students in the same division are further assigned to different "classes" for administrative purposes.

***Educational Content Development and Offerings***

*Content Development*

The Group maintains an experienced team of course and educational content development professionals. The course and educational content development team is dedicated to designing course offerings, as well as developing and improving a wide range of proprietary educational content, such as course outlines, quiz banks and teaching notes, for substantially all of the Group's online course offerings.

The Group regularly upgrades the educational content to make it more practical, and easier to comprehend and apply in real exams. For instance, the Group regularly releases major updates to the Group's proprietary quiz banks and mock questions for students pursuing the STE exams to reflect updates in the test topics in the government-administered STE exams. Benefiting from the Group's IT infrastructure, the course and educational content development team is able to view and analyze student performance in quiz banks and mock questions, which enables them to identify weaknesses in the educational content and make timely adjustments and upgrades accordingly. The course and educational content development team also seeks feedbacks from teachers and students regarding the effectiveness of the Group's educational content, through online questionnaires or in-person meetings.

In addition to the Group's proprietary educational content, the course and educational content development professionals also design and recommend to the teachers' best practices in teaching methods. While the teachers retain substantial control of and flexibility in the way their classes are taught, the course and educational content development professionals continually work closely with them to ensure the Group's courses and educational content are delivered in an engaging, effective manner. The Group uses Learning Outcome Trees to help the Group structure and deliver the Group's educational content offerings, including course outlines, teaching notes and quiz banks, more effectively.

*Content Offerings*

The Group supports the learning experience with a wide range of educational content designed to help them capture key takeaways from, and reinforce what is taught in, the live streaming lessons, and to assess learning outcomes both during and after class hours. The Group also provides the teachers with educational content to help them prepare and teach classes effectively. All of the educational content was developed by the Group's in-house research and development team and distributed electronically to students and faculty through the online platforms.

Our educational content offerings primarily consist of the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*Course outlines.* The Group develops course-specific outlines based on the curriculum requirements of the applicable government authorities and the Learning Outcome Trees to ensure high-quality teaching is delivered consistently across the Group's course offerings. As students' levels of academic ability vary, the course outlines are designed with the flexibility to address particular students' strengths and weaknesses.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*Teaching notes.* The Group offers teaching notes to the teachers providing them with roadmaps on how to spend class time effectively. The teaching notes set out the learning outcomes based on the Learning Outcome Trees, key issues and frequently tested topics of a given course as well as recommended teaching strategies. They also contain suggested allocation of time to spend on different sub-subjects and questions to ask to stimulate the desired discussion. The Group generally uses standardized teaching notes for the same courses, even taught by different teachers, to ensure consistency of teaching quality.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*Quiz banks.* The Group maintains and regularly update large quiz banks, including ones specifically designed for the state-administered STE exams. A majority of the quizzes in the quiz banks were developed in-house, leveraging the Group's understanding of the topics frequently tested in the exams as well as the significant data accumulated during teaching, while the rest are based on real exams in the past. Also, students can search within the quiz banks using keywords from Learning Outcome Trees, which has greatly improved their learning effectiveness. In addition to quiz banks, the Group also offers mock exams to provide students with realistic practice sessions for their real final exams.

**Students**

------

The Group has a large student base, primarily as a result of the Group's well-established brand and effective sales and marketing efforts. In 2023, 2024 and 2025, the Group had 1,131,435, 1,067,128 and 979,741 students, respectively, and the Group's new student enrollments were 616,341, 674,649 and 579,788, respectively.

The Group's students are primarily working adults who generally have limited time to devote to lengthy and regular classroom studies at designated physical locations. Such students also need an engaging learning atmosphere that encourages participation and interaction, and require more assistance and supervision from their teachers and mentors.

The Group's target students generally have aspirations to obtain more knowledge, pursue higher education and improve their social and economic status. At the same time, many of them cannot identify their specific education needs or solutions for such needs, especially given that education products and services can be complex and the relatively high costs may deter them from fulfilling their educational needs. To help them meet their aspirations and understand the potential educational solutions, the Group focuses marketing and sales practices on counseling-oriented interactions and strive to deliver the courses and educational content in a highly engaging and student-friendly manner.

**Faculty**

The Group maintains a team of full-time faculty dedicated to helping students succeed. As of December 31, 2025, the Group's faculty primarily consisted of 57 teachers and 18 mentors based in Beijing and Wuhan, China.

Teachers and mentors assume different roles and responsibilities. Generally, teachers are responsible for delivering courses and educational content to students, while mentors focus on providing academic and administrative support throughout the students' learning process. We believe its different functions require different skills and personal attributes, and therefore the Group applies differentiated recruitment, training, and evaluation and compensation strategies to teachers and mentors. For risks related to the Group's faculty, see "Item 3. Key Information—3.D. Risk Factors—Risks Related to the Group's Business—The Group may not be able to continue to recruit, train and retain a sufficient number of qualified faculty members."

***Teachers***

We believe maintaining a high-quality team of teachers is the bedrock of the Group's brand and reputation, particularly given the Group's online course delivery model where each teacher is expected to cover a larger number of students than in offline, classroom-based courses. The Group monitors the total number of hours teachers teach regularly to provide both an optimal number of teachers for the Group's large student enrollments and adequate teaching assignments for each of the teachers. Most of the teachers are full-time employees, while the Group also engage part-time teachers. For part-time teachers, the Group enters into agreements with qualified individuals and pays for the classes taught by them, or it collaborates with third party companies that arrange teachers to teach classes and pays for the teaching services rendered. The training the Group provides to teachers is designed to allow teachers to develop their own teaching style and methodology while maintaining high teaching quality.

*Recruitment*

The Group hires the Group's teachers based on numerous criteria, including educational backgrounds, teaching experience, and performance in mock lessons. The Group typically looks for candidates with a bachelor's degree from a top university or college in China or a master's or higher degree. Additionally, given the interactive nature of the live streaming lessons, the Group looks for teachers with strong communication skills, great passion for teaching and excellent ability of working under pressure.

*Training and support*

The Group offers standard training programs to newly-hired teachers. The Group also imposes a probation period and requires each newly hired teacher to pass a number of internal qualification tests throughout the probation to be formally employed as full-time teachers. The Group also provides on-the-job training on instructional and communication skills to teachers on a regular basis. The Group's proprietary IT system is key to the teacher training efforts as it not only allows them to monitor student engagement and academic performance on a real time basis but also to adjust teaching methodology and strategy accordingly to keep students engaged.

*Evaluation and compensation*

The Group has developed a fully-digital and systematic assessment approach that provides teachers with transparent and helpful feedback that serves as the foundation for their professional development and helps them to build fulfilling careers with us. The Group adopts a comprehensive set of key performance indicators, or metrics, to evaluate teacher performance. These metrics include student attendance rate and student satisfaction, among others. The Group also collects student reviews after each class and closely monitors the educational content delivered by teachers to facilitate teacher evaluation efforts and to improve teaching quality. In addition, the Group uses mock lessons to assess a teacher's teaching skills and ability to engage students in a live streaming course setting, especially in instances where multiple teachers are

------

competing to teach the same course.

The Group pays teachers base salaries and service fees generally on a per-lesson basis. The service fees per lesson of a teacher are based primarily on his or her rating and other factors, such as student reviews and exam results. To incentivize teachers, the Group also provides them with discretionary, merit-based bonuses based on their performance, measured by selected metrics. The Group enters into with each teacher a standard employment agreement typically for an initial term of three years which automatically renews at the end of each term.

***Mentors***

The mentors' principal role is to provide academic guidance and support to students on a daily basis to help navigate their way throughout the entire duration of studies. The mentors' roles and responsibilities typically include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•understanding and responding to student inquiries and concerns;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•monitoring students' learning progress as well as their overall academic and personal development;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•providing psychological support to help students cope with the challenging aspects of their studies, particularly in a rigorous academic environment; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•encouraging students to share ideas and learning experience and achievements with peers and faculty to foster a sense of community and teamwork spirit.

*Recruitment*

The Group tends to look for mentors who demonstrate excellent interpersonal and communication skills and a commitment in participating in the education profession and impacting a diverse audience. The Group typically requires mentors to possess a bachelor's degree.

*Training and support*

The Group provides mentors with an orientation program and periodic on-the-job training to improve their ability to engage and build relationships with students. The Group also provides mentors with training opportunities that address specific challenges. The Group has also introduced systems and tools that enable teachers to monitor student activities and outcomes and take appropriate actions when the students demonstrate a low level of engagement.

*Evaluation and compensation*

The Group uses various metrics in terms of student engagement to measure the performance of mentors. These metrics include student's class attendance, refund request rate, as well as the percentage of outperforming students. With each of mentors the Group enters into a standard employment agreement typically for an initial term of three years which automatically renews at the end of each term.

**Marketing, Branding and Sales**

The Group's marketing philosophy is to promote the Group's services to prospective students in a cost-effective manner based on the Group's deep understanding of their unique profile and needs. The Group has acquired many of the existing students through effective marketing campaigns focused on showing how the Group's services can address their specific educational needs. At the same time, the Group markets services to a larger group of prospective students who are not aware of solutions available to satisfy their needs through tailored marketing efforts designed to awaken their potential demands and navigate them through their decision-making process.

The Group has built a large, well-trained professional sales and marketing team. As of December 31, 2025, the Group had a total of 1,151 sales and marketing personnel. The Group maintains sales and marketing personnel in major regional markets, such as Beijing, Wuhan, Shenzhen and Guangzhou. The Group's sales and marketing force adopt sales and marketing strategies customized based on the needs and profile of prospective students in different markets. The Group divides the sales and marketing personnel into different teams, each dedicated to executing marketing strategies in a particular course offering or demographics.

***Advertising, Marketing and Branding***

The Group's search engine marketing channels effectively target students who possess preliminary interest in the

------

Group's services. The Group purchases key words from major search service providers in China, such as Baidu, and enhances returns from search engine marketing channels using search engine optimization techniques. The Group monitors end-to-end performance metrics of search engine marketing channels on a continuous basis.

The Group also generates leads online through mobile marketing channels, which mainly include display advertising on leading mobile news apps, as well as social media platforms and online shopping platforms. The display advertising formats the Group uses generally include launch screen display, banners, text hyperlinks, videos and rich media. The Group also operates branded official accounts on Weixin/WeChat, Sina Weibo, Tik Tok and other social media platforms to raise brand awareness and increase sales leads generated on these platforms. We believe that the Group's mobile marketing efforts are particularly effective in awakening potential demands of prospective students who have not yet developed a specific learning plan.

The terms of the agreements the Group enters into with the search engine and mobile marketing partners are typically one year. The Group pays the search engine and mobile marketing partners generally on a cost-per-click basis.

***Counseling-Oriented Sales***

*Counseling services*

To convert leads generated into student enrollments, the Group provides customized, comprehensive counseling to prospective students throughout the lead nurturing and enrollment cycle. This counseling-oriented sales approach is supported by a capable sales team consisting of live chat personnel, call center staff and recruitment consultants based in the Group's regional enrollment centers. The Group provides extensive training to sales team to ensure they are capable of explaining course offerings, addressing questions and concerns, and recommending courses that best suit prospective students' learning objectives. The Group also uses data analytics tools and models to identify a prospective student's educational needs, which helps the sales team provide tailor-made counseling services.

*Enrollment process*

The Group uses multi-layer lead-nurturing strategies to acquire new student enrollments in a cost-effective manner. Each of the leads generated are initially directed to the live chat support team who is responsible for answering prospective students' enquires, encouraging them to register with the Group's platforms, and collecting necessary information. Once a prospective student indicates an interest in purchasing the courses, the Group matches such student with the most suitable sales professional based on data analytics and tools. Such sales professional will follow up with the prospective student. In addition, the Group launches advertisements on various platforms, where the Group is able to obtain the contact information of the prospective students if they indicate interest in the Group's courses. The Group then invites prospective students to join the online learning group and provide them with access to the trial courses. A prospective student that has signed up for the courses will be directed to the local enrollment centers to complete course purchase and registration with the assistance of the enrollment consultants. The enrollment consultants are also responsible for providing counseling services to enrolling students and guiding them through the payment process. Students can also choose to complete the purchase and enrollment process entirely online.

**IT Infrastructure and Capabilities**

The Group devotes significant resources to maintaining a reliable, scalable and secure IT infrastructure. The Group has built the integrated IT infrastructure primarily based on tools, technologies and platforms that the Group has developed in-house and, to a lesser extent, third-party software and applications that the Group has licensed or purchased.

The Group maintains a dedicated IT development and support team. As of December 31, 2025, the Group had 115 technology development personnel.

***Genesis***

The Group's IT infrastructure is critical to supporting the pursuit of excellent student experience and optimal operating efficiency. The Group has developed Genesis, the Group's proprietary integrated IT infrastructure, to support and connect students and employees during every major aspect of business operations, encompassing marketing, sales, course delivery and development, and operation management.

Powering various services and functions, including information and data transmission and sharing, centralized data tracking and data analytics, Genesis is composed of both student interface and employee interface. For one thing, the student interface supports applications and platforms that enable students to enroll in courses, attend classes, access educational content, interact within the Group's virtual community, and engage in other learning activities throughout their service periods; for another thing, Genesis also incorporates different subsets of functions used by the Group's employees, ranging from teachers and mentors to the marketing and sales personnel. The employee interface is specifically customized to provide the employees with information and data most relevant to their responsibilities. In addition, Genesis supports a centralized database allowing its users, including students and employees, to contribute, share and store content and data

------

across various applications and platforms.

The Group launched the personalized study programs in 2018. This in-house developed software uses machine learning and natural language processing technology to analyze student behavior and their level of understanding of specific courses. Based on this analysis, the Group is able to predict test results, with a high accuracy rate, and develop tailor-made learning solutions that are designed to improve study outcomes.

***Mobile Platforms***

The Group is one of the first movers in China's education sector to deliver interactive education services via mobile platforms, which has enabled students to learn and connect with fellow students and faculty in a more efficient and flexible manner. The Group's *Sunlands* mobile app, available on both iOS and Android, is built with a clear and functional interface that enables access to course and educational content offerings and virtual learning community. The Group has also built mobile WAP pages which allow students and faculty to enjoy a similar level of functionality as the Group's mobile app without installation.

**Tuition and Fees**

The Group's tuition fees, including academic fees and registration fees, are charged generally on a per-program basis. From time to time, the Group offers tuition discounts under various marketing campaigns and promotions. For example, discounts may also be made available to students who purchase multiple courses at a time. The Group accepts fee payments through major third-party online payment solutions in China, including Alipay, Union Pay and WeChat Pay, as well as bank transfers and credit cards.

Students typically self-finance their education or obtain financing from third-party financing programs that cooperate with us. The Group currently offers the following two payment options to students:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*Lump-sum prepayment option*. Under a prepaid payment plan, a student is required to make a one-time, lump-sum payment of the tuition to the Group directly at the beginning of the academic period.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*Installment payment plan*. The Group offers an installment payment option that enables eligible students to obtain loans from accredited credit providers in China to finance all or part of their tuition. The credit providers perform credit assessment, approve loan applications, provide the funds and collect delinquent payments. Once a student's loan application is approved by the credit provider, the tuition will be fully paid to the Group by such credit provider. The Group also partners with credit intermediaries, who connect students with credit providers. Under the loan agreement between the borrowing student and the lending credit provider, the borrowing student is required to repay the loan principal in installments over a period generally ranging from 3 to 12 months. Under the cooperation agreement between the Group and each credit provider, the Group is responsible for making interest payments under a student loan to the lending credit provider. Interest payments and service fees are recorded as a reduction to the total contractual tuition price. The Group generally does not guarantee the payment of the loan principal by the students. See "Item 3. Key Information—3.D. Risk Factors—Risks Related to the Group's Business—The Group may face risks associated with the installment tuition payment plan the Group offers to its students." In 2023, 2024 and 2025, the Group's student loan coverage ratios were 1.3%, 1.9% and 1.7%, respectively. During the same periods, the Group made interest payments of RMB1.5 million, RMB1.7 million and RMB1.9 million (US$0.3 million), respectively, to the credit providers.

The Group generally offers students a full, unconditional refund within 24 hours upon enrollment. If a student requests a refund after taking at least one live streaming course lasting 30 minutes due to any material academic issue associated with the Group's courses within certain refund period, the Group offers a refund excluding the registration fees and the fees of delivered courses upon the Group's confirmation. In addition, the Group offers students a refund for the undelivered courses excluding the registration fees. Starting from June 2019, the Group offers such refund during the entire service period. When calculating gross billings for a specific period, the Group deducts the total amount of refunds from the total amount of cash received for the sale of course packages for such period.

**Intellectual Property**

Despite the Group's efforts to protect itself from infringement or misappropriation of the Group's intellectual property rights, unauthorized parties may attempt to copy or otherwise obtain and use the Group's intellectual property. In the event

------

of a successful claim of infringement and the Group's failure or inability to develop non-infringing intellectual property or license the infringed or similar intellectual property on a timely basis, the Group's business could be harmed. See "Item 3. Key Information—3.D. Risk Factors—Risks Related to the Group's Business—The Group may from time to time be subject to infringement claims relating to intellectual properties of third parties." and "Item 3. Key Information—3.D. Risk Factors—Risks Related to the Group's Business—If the Group fails to protect the Group's intellectual property rights, the Group's brand and business may suffer."

**Competition**

The Group primarily competes with offline, classroom-based education service providers. Additionally, the Group expects to face competition as a result of new entrants to the adult online education market and the adult personal interest learning market in China, including established education service providers that had not previously offered such courses. The Group competes with the Group's competitors for student enrollments and engagement, high-quality faculty members, sales and marketing effectiveness, among other things.

We believe that the principal competitive factors in China's adult online education market and adult personal interest learning market include the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•brand awareness and reputation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•scope of course offerings;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•course pricing;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•interactive, engaging and customized learning experience;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•teaching quality and level of academic and administrative student support;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•ease of deployment and use of the course delivery format; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•expertise in sales and marketing, and student acquisition and retention; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•proven track record of performance.

We believe the Group competes favorably on the basis of these factors. The Group's ability to remain competitive will depend, to a great extent, upon the Group's ability to consistently deliver high-quality course offerings and acquire, support and retain students. Some of the Group's present and future competitors may have longer operating histories, larger teams of teaching faculty and supporting staff and greater financial, technical, marketing and other resources. For a discussion of risks relating to competition, see "Item 3. Key Information—3.D. Risk Factors—Risks Related to the Group's Business—The Group faces intense competition in the Group's industry, which could divert student to the Group's competitors, lead to pricing pressure and loss of market share, and significantly reduce the Group's gross billings and net revenues."

**Data Privacy and Security**

We believe data security is critical to the Group's business operation because data is the foundation of the Group's competitive advantages. The Group has internal rules and policy to govern how the Group may use and share personal information, as well as protocols, technologies and systems in place to ensure that such information will not be accessed or disclosed improperly. Users must acknowledge the terms and conditions of the user agreement before using the Group's products, under which they consent to the Group's collection, use and disclosure of their data in compliance with applicable laws and regulations.

From an internal policy perspective, the Group limits access to the servers that store user and internal data on a "need-to-know" basis. The Group also adopts a data encryption system intended to ensure the secured storage and transmission of data, and prevent any unauthorized member of the public or third parties from accessing or using the Group's data in any unauthorized manner. Furthermore, the Group implements comprehensive data masking of user data for the purpose of fending off potential hacking or security attacks.

**Insurance**

The Group does not maintain any liability insurance or property insurance policies covering students, equipment and facilities for injuries, death or losses due to fire, earthquake, flood or any other disaster. Consistent with customary industry practice in China, the Group does not maintain business interruption insurance, nor does it maintain key-man insurance.

**Licenses and Approvals**

See "Item 3. Key Information—Licenses and Approvals" for details.

**Regulations Relating to Foreign Investment Restrictions**

According to the latest Special Administrative Measures for the Entry of Investment (Negative List), or the Negative List, promulgated by the Ministry of Commerce, or MOFCOM and the National Development and Reform Commission, or NDRC, effective on November 1, 2024, foreign investors shall not engage in the prohibited activities listed in the Negative List. Pursuant to the latest Negative List, the provision of value-added telecommunications services falls in the category of restricted activities and, with a few exceptions, the percentage of foreign ownership cannot exceed 50% (except for e-commerce, domestic multi-party communication, store-and-forward and call center).

The latest negative list further provides that domestic companies engaged in foreign investment prohibited business and intend to offer and list securities in overseas markets shall obtain approval from relevant government authorities.

**The PRC Foreign Investment Law**

On March 15, 2019, the Standing Committee of the National People's Congress published the Foreign Investment Law, or the FIL, which became effective on January 1, 2020. The FIL is expected to replace the trio of existing laws regulating foreign investment in China, namely, the Sino-foreign Equity Joint Venture Enterprise Law, the Sino-foreign Cooperative Joint Venture Enterprise Law and the Wholly Foreign-invested Enterprise Law, together with their implementation rules and ancillary regulations. The existing foreign-invested enterprises established prior to the effective of the FIL may keep their corporate forms within five years. Pursuant to the FIL, "foreign investors" means natural person, enterprise, or other organization of a foreign country, "foreign-invested enterprises" (FIEs) means any enterprise established under PRC law that is wholly or partially invested by foreign investors and "foreign investment" means any foreign investor's direct or indirect investment in mainland China, including: (i) establishing FIEs in mainland China either individually or jointly with other investors; (ii) obtaining stock shares, stock equity, property shares, other similar interests in Chinese domestic enterprises; (iii) investing in new projects in mainland China either individually or jointly with other investors; and (iv) making investment through other means provided by laws, administrative regulations, or State Council provisions.

The FIL stipulates that China implements the management system of pre-establishment national treatment plus a negative list to foreign investment and the government generally will not expropriate foreign investment, except under special circumstances, in which case it will provide fair and reasonable compensation to foreign investors. Foreign investors are barred from investing in prohibited industries on the negative list and must comply with the specified requirements when investing in restricted industries on that list. When a license is required to enter a certain industry, the foreign investor must apply for one, and the government must treat the application the same as one by a domestic enterprise, except where laws or regulations provide otherwise. In addition, foreign investors or FIEs are required to file information reports and foreign investment shall be subject to the national security review.

On December 26, 2019, the Supreme People's Court of the PRC promulgated the Interpretation of the Supreme People's Court on Several Issues Concerning the Application of the Foreign Investment Law of the PRC, effective as of January 1, 2020, pursuant to which "investment contracts" shall mean the relevant agreements formed as a result of direct or indirect investments in the PRC by foreign investors, i.e. foreign natural persons, foreign enterprises or other foreign organizations, including contracts for establishment of foreign investment enterprises, share transfer contracts, equity transfer contracts, contracts for transfer of property or other similar interests, contracts for newly-built projects, etc. Where a party concerned claims that an investment contract is invalid for investing in prohibited industries as stipulated in the Negative List for foreign investment access or due to violation of specified administrative measures in restricted industries, the People's Court shall support such claim.

On December 26, 2019, the State Council published the Implementation Rules of Foreign Investment Law, which came into effect on January 1, 2020. The Implementation Rules of Foreign Investment Law restates certain principles of the FIL and further provides, among others, (i) an FIE's investment within the territory of PRC is also subject to the FIL and the Implementation Rules of Foreign Investment Law; (ii) an FIE may, within five years following January 1, 2020, choose to amend its legal form or the corporate governance and complete amendment registration, or to keep its original legal form or the corporate governance; (iii) the provisions regarding the transfer of equity interests, distribution of profits and remaining assets as stipulated in the contracts among the joint venture parties of an existing FIE may survive the FIL after such FIE amends its legal form or the corporate governance in accordance with relevant applicable laws.

On December 19, 2020, the NDRC and the MOFCOM jointly promulgated the Measures on the Security Review of Foreign Investment, effective on January 18, 2021, which sets forth provisions concerning the security review mechanism on foreign investment, including the types of investments subject to review, review scopes and procedures, among others. The Office of the Working Mechanism of the Security Review of Foreign Investment, or the Office of the Working Mechanism will be established under the NDRC, who will carry out routine work of security review on foreign investment. Foreign investor or relevant parties in China must declare the security review to the Office of the Working Mechanism prior to (i) the investments in the military industry, military industrial supporting and other fields relating to the security of national defense, and investments in areas surrounding military facilities and military industry facilities; and (ii)

------

investments in important agricultural products, important energy and resources, important equipment manufacturing, important infrastructure, important transport services, important cultural products and services, important information technology and internet products and services, important financial services, key technologies and other important fields relating to national security, and obtain control in the target enterprise. Control exists when the foreign investor (i) holds over 50% equity interests in the target, (ii) has voting rights that can materially impact on the resolutions of the board of directors or shareholders meeting of the target even when it holds less than 50% equity interests in the target, or (iii) has material impact on target's business decisions, human resources, accounting and technology, etc.

On December 30, 2019, MOFCOM and the SAMR, jointly issued the Measures for Reporting of Foreign Investment Information, which came into effect on January 1, 2020. Since January 1, 2020, for foreign investors carrying out investment activities directly or indirectly in the PRC, foreign investors or foreign-invested enterprises shall submit investment information through certain system operated by SAMR. Foreign investors or foreign-invested enterprises shall disclose their investment information by submitting reports for their establishments, modifications and cancellations and their annual reports. If a foreign-invested enterprise investing in the PRC has finished submitting its reports for its establishment, modifications and cancellation and its annual reports, the relevant information will be shared by the competent market regulation department to the competent commercial department, and does not require such foreign-invested enterprise to submit the reports separately.

**M&A Regulations and Overseas Listings**

The MOFCOM, the State Assets Supervision and Administration Commission, the SAT, the SAMR, the CSRC and SAFE jointly adopted the M&A Rules. The M&A Rules establish procedures and requirements that could make some acquisitions of PRC companies by foreign investors more time-consuming and complex, including requirements in some instances that the MOFCOM be notified in advance of any change-of-control transaction in which a foreign investor takes control of a PRC domestic enterprise where any of the following situations exist: (i) the transaction involves an important industry in China, (ii) the transaction may affect national "economic security," or (iii) the PRC domestic enterprise has a well-known trademark or historical Chinese trade name in China. Complying with the requirements of the M&A Rules to complete acquisitions of PRC companies by foreign investors could be time-consuming, and any required approval processes, including obtaining approval from the MOFCOM, may delay or inhibit the ability to complete such transactions.

On July 6, 2021, General Office of the State Council of the PRC together with another authority jointly promulgated the Opinions on Strictly Cracking Down on Illegal Securities Activities, or the Securities Activities Opinions, which called for the enhanced administration and supervision of overseas-listed China-based companies, proposed to revise the relevant regulation governing the overseas issuance and listing of shares by such companies and clarified the responsibilities of competent domestic industry regulators and government authorities.

On February 17, 2023, with the approval of the State Council, the CSRC released the Trial Administrative Measures of Overseas Securities Offering and Listing by Domestic Companies, or the Overseas Listing Trial Measures, and five supporting guidelines, effective on March 31, 2023. According to the Overseas Listing Trial Measures, (1) domestic companies that seek to offer or list securities overseas, either in direct or indirect means, are required to report and file required documents with the CSRC; domestic companies that have been listed on a foreign stock exchange prior to the effective date of the Overseas Listing Trial Measures are required to file with the CSRC within three working days of the completion of fund raising activities on the same overseas capital market and shall make required filing immediately after submitting application for their listing or offering securities in other overseas capital markets; if a domestic company fails to complete the filing procedure or conceals any material fact or falsifies any major content in its filing documents, such domestic company may be subject to administrative penalties, such as order to rectify, warnings, fines, and its controlling shareholders, actual controllers, the person directly in charge and other directly liable persons may also be subject to administrative penalties, such as warnings and fines; (2) if the issuer meets both of the following conditions, the overseas offering and listing shall be determined as an indirect overseas offering and listing by a domestic company: (i) any of the revenue, net profit, total assets or net assets of the domestic companies of the issuer in the most recent accounting year accounts for more than 50% of the corresponding figure in the issuer's audited consolidated financial statements for the same period; (ii) its major operational activities are carried out in China or its main places of business are located in China, or the senior managers in charge of operation and management of the issuer are mostly Chinese citizens or are domiciled in China; (3) where a domestic company seeks to indirectly offer and list securities in an overseas market, the issuer shall designate a major domestic operating entity responsible for all filing procedures with the CSRC, and where an issuer makes an application for initial public offering and listing in an overseas market, the issuer shall submit filings with the CSRC within three business days after such application is submitted.

On the same day, the CSRC also held a press conference for the release of the Overseas Listing Trial Measures and issued the Notice on Administration for the Filing of Overseas Offering and Listing by Domestic Companies, which, among others, clarifies that (1) domestic companies that have been listed on a foreign stock exchange prior to the effective date of the Overseas Listing Trial Measures are not required to go through the filing procedure immediately but may be required to go through the filing procedure if future fund raising activities are involved; (2) a six-month transition period will be granted to domestic companies which, prior to the effective date of the Overseas Listing Trial Measures, have already obtained the approval from overseas regulatory authorities or stock exchanges (such as the completion of hearing in the

------

market of Hong Kong or the completion of registration in the market of the United States), but have not completed the indirect overseas listing; if domestic companies fail to complete the overseas listing within such six-month transition period, they shall file with the CSRC according to the requirements; and (3) the CSRC will solicit opinions from relevant regulatory authorities and complete the filing of the overseas listing of companies with contractual arrangements which duly meet the compliance requirements, and support the development and growth of these companies by enabling them to utilize two markets and two kinds of resources.

On February 24, 2023, the CSRC jointly with other government authorities issued the Provisions on Strengthening Confidentiality and Archives Administration of Overseas Securities Offering and Listing by Domestic Companies, or the Overseas Listing Archives Rules, effective on March 31, 2023, as a supporting rule to the Overseas Listing Trial Measures. Pursuant to the Overseas Listing Archives Rules, domestic companies that seek to offer or list securities overseas directly or indirectly, and securities companies and securities related service providers providing services to such domestic companies shall establish confidentiality and archives administration system, adopt requisite measures to perform the responsibilities of confidentiality and archives administration, and shall not divulge state secrets and state agencies' work secrets, or harm state and public interests. The Overseas Listing Archives Rules provide, among others, that before providing or disclosing any document or material which involve state secrets or state agencies' work secrets, domestic companies shall apply to the competent government authorities for approval and file with the secrecy administration authorities for record.

**Regulation Relating to Value-added Telecommunications Services**

***Licenses for Value-Added Telecommunications Services***

The PRC Regulations on Telecommunications, or the Telecommunications Regulations, which was latest amended and came into effect on February 6, 2016, regulate telecommunications activities in China. The Telecommunications Regulations divide the telecommunications services into two categories, namely "infrastructure telecommunications services" and "value-added telecommunications services." Pursuant to the Telecommunications Regulations, operators of value-added telecommunications services must first obtain a Value-added Telecommunications Business Operating License, or VAT License, from the Ministry of Industry and Information Technology, or MIIT, or its provincial level counterparts. On July 3, 2017, the MIIT promulgated the Administrative Measures on Telecommunications Business Operating Licenses, which set forth more specific provisions regarding the types of licenses required to operate value-added telecommunications services, the qualifications and procedures for obtaining such licenses and the administration and supervision of such licenses.

According to the Catalog of Classification of Telecommunication Businesses, or the 2016 MIIT Catalog, which published by MIIT on December 28, 2015 and took effect on March 1, 2016 and were amended on June 6, 2019, internet information services, which include information release and delivery services, information search and query services, information community platform services, information real-times interactive services, and information protection and processing services, are classified as a category of value-added telecommunication services. The Administrative Measures on Internet Information Services, or ICP Measures, also promulgated by the PRC State Council on September 25, 2000 and most recently amended on December 6, 2024, set forth more specific rules on the provision of ICP services. According to ICP Measures, any company that engages in the provision of commercial ICP services shall obtain a sub-category VAT License for Internet Information Services, or ICP License, from the relevant government authorities before providing any commercial internet content services within the PRC, and when the ICP services involve areas of news, publication, and education, and if required by law or relevant regulations, specific approval from the respective regulatory authorities must be obtained prior to applying for the ICP License from the MIIT or its provincial level counterpart. Pursuant to the above-mentioned regulations, "commercial ICP services" generally refers to provision of specific information content, web page construction and other services through internet for profit making purpose. Operating the Group's online platform to provide information and services to students may be classified as commercial ICP services.

In addition to the Telecommunications Regulations and the other regulations set forth above, the provision of commercial internet information services on mobile internet apps is regulated by the Administrative Provisions on Mobile Internet Applications Information Services, which was promulgated by the Cyberspace Administration of China, or the CAC, on June 14, 2022 and came into effect on August 1, 2022. The providers of mobile internet applications are subject to requirements under these provisions, including acquiring the qualifications and complying with other requirements provided by laws and regulations and being responsible for information security. The Group currently, through subsidiaries of the VIEs, holds ICP Licenses.

On July 21, 2023, the MIIT issued a Notice on the Filing of Mobile Internet Apps, according to which, app operators shall complete the filing procedure with the provincial communications administration where it is domiciled through the "National Management System for the Basic Internet Resources". Any failure of such filing shall cause app operators prohibited from engaging in relevant apps internet information services. Network access service providers, distribution platforms and smart terminal manufacturers shall not provide network access, distribution, pre-installation and other services for apps that have not completed the filing procedures. A transition period from September 2023 to March 2024 will be granted to the apps that have carried out business before the promulgation of this Notice, or the Existing Apps,

------

within which Existing Apps shall conduct and complete the apps filling.

***Foreign Investment in Value-Added Telecommunication Services***

The Regulations on Administration of Foreign-Invested Telecommunications Enterprises, or the FITE Regulations, which took effect on January 1, 2002 and latest amended on March 29, 2022, are the key regulations that regulate foreign direct investment in telecommunications companies in China. The FITE Regulations stipulate that, except as otherwise provided by relevant laws and regulations, the foreign investor of a telecommunications enterprise is prohibited from holding more than 50% of the equity interest in a foreign-invested enterprise that provides value-added telecommunications services.

After the MOFCOM and NDRC amended the Catalog in March 2015, MIIT also issued the Circular on Removing the Restrictions on Shareholding Ratio Held by Foreign Investors in Online Data Processing and Transaction Processing (Operating E-commerce) Business on June 19, 2015, which amended the relevant provision in FITE Regulations by allowing foreign investors to own more than 50% of the equity interest in an operator of e-commerce business. However, foreign investors continue to be prohibited from holding more than 50% of the equity interest in a provider of other categories of value-added telecommunications services except for e-commerce, domestic multi-party communication, store-and-forward, and call center.

On April 8, 2024, the MIIT issued the Circular on Pilot Work of Expanding the Opening Up of Value-Added Telecommunications Services, pursuant to which, the foreign ownership limits on several services, including (i)Internet Data Center, (ii)Content Delivery Networks, (iii)Internet Access Services, (iv)online data processing and transaction, (v) information publishing platform and delivery services (except Internet news and information, online publishing, online audio-visual, Internet culture business), and (vi) information protection and processing services in designated pilot areas, are eliminated. However, this Circular are newly promulgated, there are substantial uncertainties as to its interpretation, application and enforcement.

To comply with the above-mentioned foreign ownership restrictions, the Group operates its online platform in China through the VIEs and their subsidiaries, all of the shareholders of the VIEs are PRC domestically funded entities, and the VIEs are controlled by Wuhan Zhibo, our PRC subsidiary, through a series of contractual arrangements. The VIEs hold the domain names, trademarks and facilities necessary for daily operations of the Group's online platforms in compliance with the MIIT Circular 2006. Based on our PRC legal counsel's understanding of the current PRC law, rules and regulations, the contractual arrangements among Wuhan Zhibo, the VIEs and the VIEs' shareholders and subsidiaries are valid, binding and enforceable under PRC laws and regulations currently in effect. However, we were further advised by our PRC legal counsel that there are uncertainties with respect to the interpretation and application of existing or future PRC laws and regulations and thus there is no assurance that Chinese governmental authorities would take a view consistent with the opinions of our PRC legal counsel.

**Regulation Relating to Private Education**

***Education Law of the PRC***

On March 18, 1995, the PRC National People's Congress promulgated the Education Law of the PRC, or the Education Law, which was further amended on August 27, 2009, on December 29, 2018 and on April 29, 2021, stipulates that the government formulates plans for the development of education, establishes and operates schools and other types of educational institutions, and in principle, enterprises, institutions, social organizations and individuals are encouraged to operate schools and other types of educational organizations. Comparing to the version of Education Laws that was amended and came into effect on 2009, which provided that no organization or individual may establish or operate a school or any other educational institution for commercial purposes, the current Education Law narrowed the provision prohibiting the establishment or operation of schools or other educational institutions for commercial purposes to only restricting a school or other educational institution founded with governmental funds or donated assets in the amended Education Law.

On April 20, 2022, Standing Committee of the National People's Congress, or the SCNPC, adopted the amended Vocational Education Law of the PRC, or the Amended Vocational Education Law, which became effective on May 1, 2022 and replace the previous Vocational Education Law of the PRC adopted in 1996. The Amended Vocational Education Law specifies that the vocational education is as important as regular education and that the state encourages the development of various levels and forms of vocational education, the extensive and equal participation of social forces in vocational education and the international communication and the cooperation in vocational education, and strives to improve vocational education recognition. The Amended Vocational Education Law also provides the establishment and improvement of the vocational education system, deepening cooperation between enterprises and schools, and the improvement of the vocational education guarantee system and measures.

***The Law for Promoting Private Education and its Implementing Rules***

The Law for Promoting Private Education of the PRC became effective on September 1, 2003 and was last amended on December 29, 2018, and the Implementation Rules for the Law for Promoting Private Education became effective on April 1, 2004.

The Decision of the Standing Committee of the National People's Congress on Amending the Law for Promoting Private Education of the PRC, or the Amendment, has been promulgated by Order No. 55 of the President of the PRC on November 7, 2016 and came into force on September 1, 2017.

Under the Amendment, sponsors of private schools may choose to establish non-profit or for-profit private schools at their own discretion. Nonetheless, school sponsors are not allowed to establish for-profit private schools that are engaged in compulsory education. In other words, the schools engaged in compulsory education should retain their non-profit status after the Amendment comes into force. The Amendment further establishes a new classification system for private schools to be classified by whether they are established and operated for profit-making purposes.

On April 7, 2021, the State Council published the amendment to the Regulations on the Implementation of the Law for Promoting Private Education of the PRC, or Amended Implementing Rules, which became effective on September 1, 2021. The Amended Implementing Rules stipulates that online education activities using internet technology are encouraged by the regulatory authorities and shall comply with laws and regulations related to internet management. A private school using internet technology to conduct education activities shall obtain an appropriate private school operating permit and shall establish and implement internet security management systems and take technical security measures. Upon discovery of any information whose release or transmission is prohibited by applicable laws or regulations, the private school shall immediately cease the transmission of that information and take further remedial actions, such as deleting that information, to prevent it from spreading. Records pertaining to the situation shall be kept and reported to the appropriate authorities. The Amended Implementing Rules further stipulates that any entities or individuals shall not control any schools providing compulsory education or any non-profit schools providing pre-school education through merger, acquisition or contractual arrangements. A private school providing compulsory education shall not conduct any transaction with any related party. Any other private school conducting any transaction with any related party shall follow the principles of openness, fairness and impartiality, fix the price reasonably and regulate the decision-making, and shall not damage the state interests, the interests of the school or the rights and interests of the teachers and students. A private school shall establish an information disclosure system for related party transactions and relevant government authorities shall enhance the supervision on the agreements entered into between non-profit private schools and its related party and shall review such transactions on an annual basis.

On December 29, 2016, the State Council issued the Several Opinions of the State Council on Encouraging the Operation of Education by Social Forces and Promoting the Healthy Development of Private Education, or the State Council Opinions, which requires to ease the access to the operation of private schools and encourages social forces to enter the education industry. The State Council Opinions also provides that each level of the people's governments shall increase their support to the private schools in terms of financial investment, financial support, autonomy policies, preferential tax treatments, land policies, fee policies, autonomy operation, protecting the rights of teachers and students etc. Further, the State Council Opinions require each level of the people's governments to improve its local policies on government support to for-profit and non-profit private schools by ways of preferential tax treatments etc. In addition, under the State Council Opinions, private schools shall strengthen its construction of the Chinese Communist Party, or the CCP, and further the theoretical system of Socialism with Chinese Characteristics by introducing such system into textbooks and teaching programs. The construction of the CCP's organizations by the private schools as well as the CCP's leadership to private schools shall constitute an important part of such schools' annual inspection.

On December 30, 2016, the MOE, Ministry of Civil Affairs, State Administration for Industry and Commerce (the predecessor of the State Administration for Market Regulation), the Ministry of Human Resources and Social Welfare and the State Commission Office of Public Sectors Reform jointly issued the Implementation Rules on the Classification Registration of Private Schools to reflect the new classification system for private schools as set out in the Amendment. Generally, if a private school established before promulgation of the Amendment chooses to register as a non-profit school, it shall amend its articles of association, continue its operation and complete the new registration process.

Uncertainties exist with respect to the interpretation and application of the existing and future laws and regulations governing online private education industry, as well as how the local government would promulgate implementing rules relating to the specific requirements applicable to online education service providers like the Group. See "Item 3. Key Information—3.D. Risk Factors—Risks Related to the Group's Business—The Group faces risks associated with the lack of a private school operating permit for 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."

If the filing requirements are violated and not rectified in a timely manner, the MOE or its local counterparts may revoke the filing of such educational mobile app, blacklist such provider, report such provider to the education system, and prohibit such provider from submitting any filings for six months. The MOE established a public channel that can be used to submit complaints with respect to educational apps and set a penalty points system based on the severity of the complaints. For serious complaints substantiated by relevant government authorities, an appropriate number of penalty points is recorded for the relevant educational app provider, and remedial measures also may be required. In the event that an educational app provider receives 12 or more penalty points within 12 months or certain types of serious complaints, the MOE may revoke such provider's filing, blacklist such provider, remove its educational app from the app store, publicize the complaint or prohibit such provider from submitting any filings for six months.

Capital account items, such as direct equity investments, loans and repatriation of investment, unless expressly exempted by laws and regulations, still require prior approval from SAFE or its local counterparts for conversion of RMB into a foreign currency, such as U.S. dollars, and remittance of the foreign currency outside of the PRC. Payments for transactions that take place within the PRC must be made in RMB. Foreign currency revenues received by PRC companies may be repatriated into China or retained outside of China in accordance with requirements and terms specified by SAFE.

According to the Circular on Administration of Foreign Exchange on Further Promoting the Facilitation of Cross-border Trade and Investment promulgated by SAFE on October 23, 2019, which was amended by SAFE Notice on Further Deepening the Reform to Facilitate Cross-border Trade and Investment on December 4, 2023, non-investment FIEs are allowed to make domestic equity investment with their capital funds provided that the existing negative list for foreign investment are complied with and the projects invested thereby in China are true and comply with applicable laws and regulations.

***Dividend Distribution***

Wholly foreign-owned enterprises and Sino-foreign equity joint ventures in the PRC may pay dividends only out of their accumulated profits, if any, as determined in accordance with PRC accounting standards and regulations. Additionally, these foreign-invested enterprises may not pay dividends unless they set aside at least 10% of their respective accumulated profits after tax each year, if any, to fund certain reserve funds, until such time as the accumulative amount of such fund reaches 50% of the enterprise's registered capital. In addition, these companies also may allocate a portion of their after-tax profits based on PRC accounting standards to employee welfare and bonus funds at their discretion. These reserves are not distributable as cash dividends.

***Regulations Relating to Foreign Exchange Registration of Overseas Investment by PRC Residents***

SAFE Circular on Relevant Issues Relating to Domestic Resident's Investment and Financing and Roundtrip Investment through Special Purpose Vehicles, or Circular 37, issued by SAFE and effective in July 4, 2014, regulates foreign exchange matters in relation to the use of special purpose vehicles, or SPVs, by PRC residents or entities to seek offshore investment and financing and conduct round trip investment in China. Under Circular 37, a SPV refers to an offshore entity established or controlled, directly or indirectly, by PRC residents or entities for the purpose of seeking offshore financing or making offshore investment, using legitimate domestic or offshore assets or interests, while "round trip investment" refers to the direct investment in China by PRC residents or entities through SPVs, namely, establishing foreign-invested enterprises to obtain the ownership, control rights and management rights. Circular 37 requires that, before making contribution into an SPV, PRC residents or entities are required to complete foreign exchange registration with the SAFE or its local branch. SAFE Circular 37 further provides that option or share-based incentive tool holders of a non-listed SPV can exercise the options or share incentive tools to become a shareholder of such non-listed SPV, subject to registration with SAFE or its local branch.

PRC residents or entities who have contributed legitimate domestic or offshore interests or assets to SPVs but have yet to obtain SAFE registration before the implementation of Circular 37 shall register their ownership interests or control in such SPVs with SAFE or its local branch. An amendment to the registration is required if there is a material change in the SPV registered, such as any change of basic information (including change of such PRC residents, name and operation term), increases or decreases in investment amount, transfers or exchanges of shares, or mergers or divisions. Failure to comply with the registration procedures set forth in Circular 37, or making misrepresentation on or failure to disclose controllers of foreign-invested enterprise that is established through round-trip investment, may result in restrictions on the foreign exchange activities of the relevant foreign-invested enterprises, including payment of dividends and other distributions, such as proceeds from any reduction in capital, share transfer or liquidation, to its offshore parent or affiliate, and the capital inflow from the offshore parent, and may also subject relevant PRC residents or entities to penalties under PRC foreign exchange administration regulations. On February 13, 2015, SAFE further promulgated the Circular on Further Simplifying and Improving the Administration of the Foreign Exchange Concerning Direct Investment, or SAFE Circular 13, which took effect on June 1, 2015. This SAFE Circular 13 has amended SAFE Circular 37 by requiring PRC residents or entities to register with qualified banks rather than SAFE or its local branch in connection with their establishment or control of an offshore entity established for the purpose of overseas investment or financing. SAFE Circular 13 further provides that annual inspection of inbound foreign direct investments and outbound overseas direct investments is canceled. Instead, relevant entities or individuals, as the case may be, shall register data and information with respect to their inbound foreign direct investments and outbound overseas direct investment interests with SAFE.

***Regulations on Stock Incentive Plans***

Pursuant to the Notice on Issues Concerning the Foreign Exchange Administration for Domestic Individuals Participating in Stock Incentive Plan of Overseas Publicly Listed Company, or Circular 7, issued by SAFE in February 2012, employees, directors, supervisors and other senior management participating in any stock incentive plan of an overseas publicly listed company who are PRC citizens or who are non-PRC citizens residing in China for a continuous period of not less than one year, subject to a few exceptions, are required to register with SAFE through a domestic qualified agent, which could be a PRC subsidiary of such overseas listed company, and complete certain other procedures. If the Group fails to complete the SAFE registrations, such failure may subject the Group to fines and legal sanctions and may also limit our ability to contribute additional capital into our wholly foreign-owned subsidiary in China and limit such subsidiary's ability to distribute dividends to us.

In addition, the State Administration for Taxation has issued certain circulars concerning employee share options or restricted shares. Under these circulars, the employees working in the PRC who exercise share options or are granted restricted shares will be subject to PRC individual income tax. The PRC subsidiaries of such overseas listed company have obligations to file documents related to employee share options or restricted shares with relevant tax authorities and to withhold individual income taxes of those employees who exercise their share options. If the employees fail to pay or the PRC subsidiaries fail to withhold their income taxes according to relevant laws and regulations, the PRC subsidiaries may face sanctions imposed by the tax authorities or other PRC government authorities.

***Regulations on Foreign Debt***

A loan made by a foreign entity as direct or indirect shareholder in an FIE is considered to be foreign debt in China and is regulated by various laws and regulations, including the Regulation of the People's Republic of China on Foreign Exchange Administration, the Interim Provisions on the Management of Foreign Debts, the Statistical Monitoring of Foreign Debts Tentative Provisions, and the Administrative Measures for Registration of Foreign Debts. Under these rules and regulations, a shareholder loan in the form of foreign debt made to a PRC entity does not require the prior approval of SAFE. However, such foreign debt must be registered with and recorded by SAFE or its local branches within 15 business days after entering into the foreign debt contract. Pursuant to these rules and regulations, the maximum amount of the aggregate of (i) the outstanding balance of foreign debts with a term not longer than one year, and (ii) the accumulated

------

amount of foreign debts with a term longer than one year, of an FIE shall not exceed the difference between its registered total investment and its registered capital, or Total Investment and Registered Capital Balance.

On January 12, 2017, PBOC promulgated Notice of the People's Bank of China on Issues Concerning Macro Prudential Management of Full Scale Cross-border Financing or PBOC Circular 9. According to PBOC Circular 9, PBOC established a cross-broader financing regulation system based on the capital or net assets of the micro main body under macro prudential rules, and the legal entities and financial institutions established in PRC including the branches of foreign banks registered in China but excluding government financing vehicles and real estate enterprise, may carry out cross-border financing of foreign currency in accordance with relevant regulations of such system. PBOC Circular 9 provides that, among other things, the outstanding amount of the foreign currency for the entities in cross-border financing shall be limited to the Upper Limit of the Risk Weighted Balance of such entity, which shall be calculated according to the formula provided in PBOC Circular 9; the enterprise shall, after signing the contract for cross-border financing, but not later than three business days before the withdrawal of the borrowing funds, file with the local branches of SAFE for the cross-border financing through SAFE's capital project information system. PBOC Circular 9 also provides that during the one-year period started from January 11, 2017, foreign-invested enterprises may choose one method to carry out cross-broader financing in foreign currency either according to PBOC Circular 9 or according to the Interim Provisions on the Management of Foreign Debts. After the end of such one-year period, the method of foreign-invested enterprises to carry out cross-broader financing in foreign currency will be determined by PBOC and SAFE. To date, though the one-year period has expired, no further regulations or guidance promulgated by PBOC and SAFE in this regard.

On January 5, 2023, the NDRC promulgated the Administrative Measures for the Review and Registration of Medium and Long-Term Foreign Debts of Enterprises, or the Foreign Debts Measures, which became effective on February 10, 2023. Pursuant to the Foreign Debts Measures, PRC enterprises are not allowed to raise medium and long-term foreign debts unless and until they have completed the review and registration process and obtained the review and registration certificate issued by NDRC. Also, the Foreign Debts Measures require PRC enterprises to register with NDRC prior to making a material amendment to a medium and long-term foreign debts transaction and to submit related information to NDRC within 10 business days after each drawdown of the medium and long-term foreign debts.

**Regulations on Tax**

***PRC Enterprise Income Tax Law***

The Enterprise Income Tax Law enacted by the National People's Congress, or the PRC EIT Law, applies a uniform 25% enterprise income tax rate to both foreign-invested enterprises and domestic enterprises, except where tax incentives are granted to special industries and projects. Enterprises qualified as "High and New Technology Enterprises" are entitled to a 15% enterprise income tax rate rather than the 25% uniform statutory tax rate. The preferential tax treatment continues as long as an enterprise can retain its "High and New Technology Enterprise" status. Enterprise income tax for qualified small profit enterprises shall be at a reduced tax rate of 20%. Under the PRC EIT Law and its implementation regulations, dividends generated from the business of a PRC subsidiary after January 1, 2008 and payable to its foreign investor may be subject to a withholding tax rate of 10% if the PRC tax authorities determine that the foreign investor is a non-resident enterprise, unless there is a tax treaty with China that provides for a preferential withholding tax rate. Distributions of earnings generated before January 1, 2008 are exempt from PRC withholding tax.

Under the PRC EIT Law, an enterprise established outside China with "de facto management bodies" within China is considered a "resident enterprise" for PRC enterprise income tax purposes and is generally subject to a uniform 25% enterprise income tax rate on its worldwide income. The Circular Regarding the Determination of Chinese-Controlled Offshore Incorporated Enterprises as PRC Tax Resident Enterprises on the Basis of De Facto Management Bodies issued by the SAT, in April 2009 regarding the standards used to classify certain Chinese-invested enterprises controlled by Chinese enterprises or Chinese enterprise groups and established outside of China as "resident enterprises," or the SAT Circular 82, clarified that dividends and other income paid by such PRC "resident enterprises" will be considered PRC-source income and subject to PRC withholding tax, currently at a rate of 10%, when paid to non-PRC enterprise shareholders. The SAT Circular 82 also subjects such PRC "resident enterprises" to various reporting requirements with the PRC tax authorities. Under the implementation regulations to the PRC EIT Law, a "de facto management body" is defined as a body that has material and overall management and control over the manufacturing and business operations, personnel and human resources, finances and properties of an enterprise. In addition, the SAT Circular 82 specifies that certain PRC-invested overseas enterprises controlled by a Chinese enterprise or a Chinese enterprise group in the PRC will be classified as PRC resident enterprises if the following are located or resided in the PRC: (i) senior management personnel and departments that are responsible for daily production, operation and management; (ii) financial and personnel decision making bodies; (iii) key properties, accounting books, the company seal, and minutes of board meetings and shareholders' meetings; and (iv) half or more of the senior management or directors who have the voting rights.

Pursuant to the Arrangement between Mainland China and the Hong Kong Special Administrative Region for the Avoidance of Double Taxation and Tax Evasion on Income, the withholding tax rate in respect to the payment of dividends by a PRC enterprise to a Hong Kong enterprise may be reduced to 5% from a standard rate of 10% if the Hong Kong enterprise directly holds at least 25% of the PRC enterprise and certain other conditions are satisfied. Pursuant to the Notice

------

of the State Administration of Taxation on the Issues concerning the Application of the Dividend Clauses of Tax Agreements, or SAT Circular 81, a Hong Kong resident enterprise must meet the following conditions, among others, in order to apply the reduced withholding tax rate: (i) it must be a company; (ii) it must directly own the required percentage of equity interests and voting rights in the PRC resident enterprise; and (iii) it must have directly owned such required percentage in the PRC resident enterprise throughout the 12 months prior to receiving the dividends. The SAT promulgated the Administrative Measures for Non-resident Taxpayers to Enjoy Treatment under Treaties, or SAT Circular 35, which became effective on January 1, 2020. SAT Circular 35 provides that non-resident enterprises are not required to obtain preapproval from the relevant tax authority in order to enjoy the reduced withholding tax. Instead, non-resident enterprises and their withholding agents may, by self-assessment and on confirmation that the prescribed criteria to enjoy the tax treaty benefits are met, directly apply the reduced withholding tax rate, and file necessary forms and supporting documents when performing tax filings, which will be subject to post-tax filing examinations by the relevant tax authorities. Accordingly, Sunlands HK may be able to benefit from the 5% withholding tax rate for the dividends it receives from Wuhan Zhibo if it satisfies the conditions prescribed under SAT Circular 81 and other relevant tax rules and regulations. However, according to SAT Circular 81 and SAT Circular 35, if the relevant tax authorities consider the transactions or arrangements the Group has are for the primary purpose of enjoying a favorable tax treatment, the relevant tax authorities may adjust the favorable withholding tax in the future.

On February 3, 2015, the SAT issued the Announcement of the State Administration of Taxation on Several Issues Concerning the Enterprise Income Tax on Indirect Property Transfer by Non-resident Enterprises, or SAT Bulletin 7, extends its tax jurisdiction to transactions involving the transfer of taxable assets through offshore transfer of a foreign intermediate holding company. Pursuant to SAT Bulletin 7, where a non-resident enterprise indirectly transfers properties such as equity in PRC resident enterprises without any justifiable business purposes and aiming to avoid the payment of enterprise income tax, such indirect transfer must be reclassified as a direct transfer of equity in PRC resident enterprise. To assess whether an indirect transfer of PRC taxable properties has reasonable commercial purposes, all arrangements related to the indirect transfer must be considered comprehensively and factors set forth in SAT Bulletin 7 must be comprehensively analyzed in light of the actual circumstances. 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.

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 non-resident investors were involved in our private equity financing, if such transactions were determined by the tax authorities to lack reasonable commercial purpose, we and our non-resident investors may become at risk of being required to file a return and taxed under SAT Bulletin 7 and/or SAT Bulletin 37 and we may be required to expend valuable resources to comply with SAT Bulletin 7 and/or SAT Bulletin 37 or to establish that we should not be held liable for any obligations under SAT Bulletin 7 and/or SAT Bulletin 37.

***PRC Value-added Tax ("VAT") in lieu of Business Tax (the "VAT Pilot Program")***

On March 23, 2016, the Ministry of Finance and the SAT issued the Circular on Comprehensively Promoting the Pilot Program of the Collection of Value-added Tax in Lieu of Business Tax. Effective from May 1, 2016, the PRC tax authorities collect VAT in lieu of Business Tax on a trial basis within the territory of China, and in industries such as construction industries, real estate industries, financial industries, and living service industries. On April 4, 2018, the Ministry of Finance and the SAT issued the Notice on the Adjustment of the Value Added Tax Rate, pursuant to which the Value Added Tax Rate of part of the taxable action is adjusted to decline. On March 20, 2019, the Ministry of Finance, the SAT and the General Administration of Customs jointly issued the Notice on the Policy Concerning Deepening the Reform of Value Added Tax, or Notice 39, which became effective on April 1, 2019. The Notice 39 further changed the Value Added Tax rate of 16% and 10% into 13% and 9%.

**Regulations Relating to Employment and Social Insurance**

The Group is subject to laws and regulations governing the Group's relationship with employees, including wage and hour requirements, working and safety conditions, and social insurance, housing funds and other welfare. The compliance with these laws and regulations may require substantial resources.

Pursuant to the PRC Labor Law effective as of January 1, 1995 (as amended on December 29, 2018) and the PRC Labor Contract Law effective as of January 1, 2008 (as amended on December 28, 2012), a written labor contract shall be executed by employer and an employee when the employment relationship is established, and an employer is under an obligation to sign an unlimited-term labor contract with any employee who has worked for the employer for ten consecutive years. Further, if an employee requests or agrees to renew a fixed-term labor contract that has already been entered into twice consecutively, the resulting contract must have an unlimited term, with certain exceptions. The employer must also pay severance to an employee in nearly all instances where a labor contract, including a contract with an unlimited term, is terminated or expires. All employers must compensate their employees equal to at least the local minimum wage standards. All employers are required to establish a system for labor safety and sanitation, strictly abide by state rules and

------

standards and provide employees with appropriate workplace safety training. In addition, the government has continued to introduce various new labor-related regulations after the Labor Contract Law. Among other things, new annual leave requirements mandate that annual leave ranging from 5 to 15 days is available to nearly all employees and further require that the employer compensate an employee for any annual leave days the employee is unable to take in the amount of three times his daily salary, subject to certain exceptions. Moreover, all PRC enterprises are generally required to implement a standard working time system of eight hours a day and forty hours a week, and if the implementation of such standard working time system is not appropriate due to the nature of the job or the characteristics of business operation, the enterprise may implement a flexible working time system or comprehensive working time system after obtaining approvals from the relevant authorities.

In addition, employers in China are obliged to pay contributions to the social insurance plan and the housing fund plan for their employees, and such contribution amount payable shall be calculated based on the employee actual salary in accordance with the relevant regulations. According to the Notice on the Reduction or Exemption of Enterprises' Social Security Contributions in Phases jointly promulgated by the Ministry of Human Resources and Social Security, the Ministry of Finance and the SAT on February 20, 2020, with effect from February 2020, with certain exceptions, based on the epidemic impact and the fund threshold, small, medium and micro enterprises and the enterprises in Hubei may be exempted from contributions to the basic pension insurance, unemployment insurance, and work injury insurance, with the exemption period not exceed five months; and contributions to such three social security contribution items by other social security participating organizations (excluding State agencies and institutions) such as large enterprises may be reduced by 50% by, with the reduction period not exceed three months. According to the relevant implementation policies in Beijing, the contributions to the basic pension insurance, unemployment insurance, and work injury insurance of large enterprise shall be reduced by 50% from February 2020 to April 2020, and the contributions of small, medium and micro enterprises will be exempted from February 2020 to June 2020.

On June 22, 2020, the Ministry of Human Resources and Social Security, the Ministry of Finance and the SAT jointly promulgated a follow-up notice regarding the reduction or exemption of enterprises' social security contributions. This notice provides that, among other things, the exemption period for small, medium and micro enterprises to contribute to the basic pension insurance, unemployment insurance, and work injury insurance shall last till the end of December 2020 and the reduction period for the large enterprises (excluding State agencies and institutions) to contribute to the basic pension insurance, unemployment insurance, and work injury insurance outside Hubei shall last till the end of June 2020 while the exemption period for the large enterprises within Hubei to contribute to the basic pension insurance, unemployment insurance, and work injury insurance shall last till the end of June 2020. The enterprises with serious difficulties in production and operation due to COVID-19 may continue to postpone the payment of social insurance premiums until the end of December 2020, and there will be no overdue fine during the period of suspension.

Not applicable.

**ITEM 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS**

You should read the following discussion together with our consolidated financial statements and the related notes included elsewhere in this annual report on Form 20-F. This discussion may contain forward-looking statements about the Group's business and operations based upon current expectations that involve risks and uncertainties. The Group's actual results may differ materially from those currently anticipated as a result of many factors, including those described under "Item 3. Key Information—3.D. Risk Factors" and elsewhere in this annual report on Form 20-F.

**5. A. Operating Results**

**Major Factors Affecting Results of Operations**

The Group operates in China's adult online education market and adult personal interest learning market, and the

------

Group's results of operations and financial condition are significantly affected by general factors affecting this market. Drivers for the Group's growth include China's rapid economic growth, continued urbanization, and rising per capita disposable income, all of which have allowed Chinese households, particularly working adults, to spend more disposable income on education. In addition, driven by a strong desire for employment, career promotion, salary increases and local residence qualification, adult online education and adult personal interest learning education in China have grown rapidly in the past several years and are expected to continue to grow in the future.

Changes to China's economy and GDP growth also have a material impact on the adult online education market and the adult personal interest learning market. In addition, the industry the Group operates in is fragmented, and the Group faces competition from traditional offline players. At the same time, the Group's results are subject to changes in the regulatory regime governing China's education industry, particularly uncertainties relating to online education services. The PRC government regulates various aspects of the Group's business and operations, including the qualification and licensing requirements for entities that provide online education services and limitations on foreign investments in the online education industry.

Additionally, we believe that the Group's results of operations and financial condition are also affected by company-specific factors, including the factors discussed below.

***Ability to respond to the evolving industry landscape and drive student acceptance of online education format***

As an online service provider, the Group benefited significantly from the increasing proliferation of the internet, in particular the mobile internet, in China. In recent years, driven by the increasing number of internet users and mobile penetration rates, China's online education industry has developed rapidly.

We believe that the online education format, as compared to traditional in-person classroom teaching, is superior as it breaks down the time and location barriers of offline education format and offers students more a flexible, convenient and cost-effective alternative. As a result, online education format has become increasingly popular among students, taking away market share from traditional offline players. For this reason, we believe the ability to continue to grow net revenues and gross billings significantly depends on the Group's ability to continue to convert students to embrace online education formats over traditional offline education format.

***Ability to increase the number of students and new student enrollments at optimal pricing***

The Group's net revenues and gross billings primarily consist of tuition payments from students and are therefore affected by the number of students and new student enrollments and the pricing of the Group's educational services.

In 2023, 2024 and 2025, the Group's new student enrollments were 616,341, 674,649 and 579,788, respectively, and the numbers of students were 1,131,435, 1,067,128 and 979,741, respectively. The Group's new student enrollments remained relatively stable in 2023 and 2024, followed by a decrease in 2025. This trend was primarily attributable to the Group's disciplined customer acquisition strategies and continued optimization of its business focus. The Group is seeking to offer a broader range of courses, foster a more a social and entertaining learning experience, and use cutting-edge technologies to improve students' learning experience and outcomes which we believe would help to achieve positive results in the Group's new student enrollments in the long run. See "Item 3. Key Information—3.D. Risk Factors—Risks Related to the Group's Business—If the Group fails to manage its business growth effectively, the success of the Group's business model will be compromised."

The Group's ability to increase the number of students and new student enrollments is primarily driven by factors including the quality of the Group's education services, the range and attractiveness of the Group's course offerings, the brand reputation, the ability to convert leads into student enrollments cost-effectively, and the availability of loans from third-party credit providers to students. See "Item 3. Key Information—3.D. Risk Factors—Risks Related to the Group's Business—The Group may face risks associated with the installment tuition payment plan the Group offers to its students." The Group's ability to attract prospective students in target markets and expand course offerings has a direct impact on maintaining growths in the number of students and new student enrollments, which in turn is subject to several other factors largely beyond the Group's control, including the perception of the effectiveness of online education as compared to offline, classroom-based courses and the popularity of the degrees, diplomas, certifications, professions, professional skills or interests students are pursuing.

The Group's pricing is affected by the overall demand, the prices and availability of competing courses, perception of the quality and effectiveness of course offerings, and the income levels that students expect to achieve upon passing the exams that they are pursuing through taking courses.

***Ability to maintain an optimal mix of course length***

The Group typically receives tuition from students (or third-party credit providers in the case of students taking loans for their tuition) upfront at the time of sale of the Group's course packages. The tuition the Group collects from a student is initially recorded as deferred revenue and is generally recognized proportionally throughout the duration of the programs

------

that student has enrolled in. For the year ended December 31, 2025, the weighted average service period of the Group's interest, professional skills and professional certification preparation courses was approximately 4 months, and the weighted average service period of the Group's degree- or diploma-oriented post-secondary courses was approximately 16 months. As of December 31, 2023, 2024 and 2025, the Group's deferred revenues were RMB1,113.9 million, RMB916.5 million and RMB585.3 million (US$83.7 million), respectively.

The Group continually evaluates the mix of course length. As the Group makes these evaluations, the Group may market and sell courses with shorter or longer durations in order to balance among various goals, including satisfying student needs, driving revenue growth, and improving visibility of future earnings, which may affect the Group's ability to increase net revenues on a continuous basis. For example, if the Group increases the percentage of courses with longer durations in total course offerings, the Group's net revenues for a given period may reduce as an increasing part of the Group's revenues may be deferred and recognized across longer periods. Any material change in the mix of course length could have a significant impact on the Group's results of operations.

***Ability to sell and market the Group's services cost-effectively***

The Group depends on the ability to sell and market the Group's services in a cost-effective manner to maintain and improve the operating margins.

Sales and marketing expenses have historically represented a substantial portion of the Group's total operating expenses. In 2023, 2024 and 2025, the Group's sales and marketing expenses were RMB1,142.2 million, RMB1,216.9 million and RMB1,137.6 million (US$162.7 million), respectively. The decrease in the sales and marketing expenses from 2024 to 2025 was mainly due to the decreases in compensation for sales personnel and the spending on branding and marketing activities focused on interest courses offerings. The Group's sales and marketing expenses are primarily composed of marketing spending and expenses incurred in relation to sales and marketing personnel. The Group's ability to lower the sales and marketing expenses as a percentage of gross billings depends on the Group's ability to improve sales and marketing efficiency and leverage the Group's existing brand value and word-of-mouth referrals in the sales and marketing efforts. In 2023, 2024 and 2025, the percentage of the Group's sales and marketing expenses divided by the Group's gross billings was 75.9%, 78.2% and 77.5%, respectively.

The Group has acquired many of the existing students through search engine marketing channels, mobile marketing channels and, to a lesser extent, offline channels. Further, the Group relies on a large sales force to provide counseling-oriented sales services to convert sales leads into enrollments. As such, the cost-effectiveness of the sales and marketing depends heavily on the ability to enhance returns from different marketing channels, as well as to improve the efficiency of the counseling-oriented sales activities. The Group also plans to further strengthen the mobile marketing endeavors, which we believe are particularly critical to attracting prospective students who are not yet aware of solutions available to satisfy their desire to pursue adult online education and adult personal interest learning education. These initiatives have placed, and will continue to place, significant strains on the ability to sell and market the Group's course offerings in an efficient and cost-effective manner.

**Key Components of Results of Operations**

***Net revenues***

The Group derives substantially all net revenues from tuition that the Group charges students for the course packages that they purchase. In 2023, 2024 and 2025, the Group generated net revenues of RMB2,159.6 million, RMB1,990.2 million and RMB2,019.9 million (US$288.8 million), respectively.

The Group generally bills students for the entire course tuition upfront at the time of sale of the course packages. The tuition the Group collects from a student is initially recorded as deferred revenue and is generally recognized proportionally over a weighted average service period of 4 months for the interest, professional skills and professional certification preparation courses and a weighted average service period of 16 months for the degree- or diploma-oriented post-secondary courses for the year ended December 31, 2025. As of December 31, 2023, 2024 and 2025, the Group had deferred revenue of RMB1,113.9 million, RMB916.5 million and RMB585.3 million (US$83.7 million), respectively. For a reconciliation of the Group's gross billings and net revenues, see "—Non-GAAP Financial Measures."

Note:

(1) The Group has included the impairment loss on long-lived assets within the income from operations as the amount was recognized for a long-lived asset to be held and used. This represents a reclassification from the unaudited full-year 2025 financial results released on March 19, 2026, where the amount was not previously presented within that subtotal. The adjustment is made to comply with the presentation requirements for impairment loss and has no impact on net income.

***Year Ended December 31, 2025 Compared to Year Ended December 31, 2024***

***Net revenues***

The Group's net revenues increased by 1.5% from RMB1,990.2 million in 2024 to RMB2,019.9 million (US$288.8 million) in 2025, primarily due to the increase in revenues generated from degree- or diploma-oriented post-secondary courses. This was mainly because the Group gradually resumed providing services for these historical orders, which students had previously requested to suspend but exceeded the maximum allowable suspension period in the contract.

***Cost of revenues***

The Group's cost of revenues decreased by 16.7% from RMB317.6 million in 2024 to RMB264.4 million (US$37.8 million) in 2025. The decrease was primarily due to declined cost of revenues from sales of goods such as learning materials and books, and declined cooperation costs.

***Gross profit***

As a result of the foregoing, the Group's gross profit increased by 5.0% from RMB1,672.6 million in 2024 to RMB1,755.5 million (US$251.0 million) in 2025, and gross margin increased from 84.0% in 2024 to 86.9% in 2025. The increase was primarily due to the contribution from the resumption of services for suspended historical orders.

------

***Operating expenses***

The Group's operating expenses decreased by 4.6% from RMB1,374.7 million in 2024 to RMB1,311.0 million (US$187.5 million) in 2025.

*Sales and marketing expenses*

The Group's sales and marketing expenses decreased by 6.5% from RMB1,216.9 million in 2024 to RMB1,137.6 million (US$162.7 million) in 2025. The decrease was mainly due to the decreases in compensation for sales personnel and the spending on branding and marketing activities focused on interest courses offerings.

*General and administrative expenses*

The Group's general and administrative expenses increased by 8.3% from RMB132.8 million in 2024 to RMB143.8 million (US$20.6 million) in 2025, driven primarily by compensation expenses related to the Group's general and administrative personnel.

*Product development expenses*

The Group's product development expenses increased by 18.2% from RMB25.0 million in 2024 to RMB29.6 million (US$4.2 million) in 2025. The increase was primarily due to increased compensation expenses related to headcount expansion of our product development personnel.

***Other income, net***

Other income, net for 2025 was RMB30.1 million (US$4.3 million), compared with RMB26.3 million in 2024.

***Net income***

As a result of the foregoing, the Group's net income for 2025 was RMB365.6 million (US$52.3 million), compared with RMB342.1 million in 2024.

***Year Ended December 31, 2024 Compared to Year Ended December 31, 2023***

See "Item 5. Operating and Financial Review and Prospects—5.A. Operating Results—Year Ended December 31, 2024 Compared to Year Ended December 31, 2023" beginning on page 86 of our Form 20-F for the fiscal year ended December 31, 2024 filed with the Securities and Exchange Commission on April 25, 2025 (Securities Act File No. 001-38423).

**Non-GAAP Financial Measures**

We use gross billings, EBITDA and adjusted EBITDA, each a non-GAAP financial measure, in evaluating the Group's operating results and for financial and operational decision-making purposes.

We define gross billings for a specific period as the total amount of cash received for the sale of course packages, net of the total amount of refunds paid in such period. For a more detailed discussion of our tuition refund policy, see "Item 4. Information on the Company—4.B. Business Overview—Tuition and Fees." The Group's management uses gross billings as a performance measurement because the Group generally bills students for the entire course tuition at the time of sale of course packages and recognize revenue proportionally over a period.

EBITDA is defined as net loss/income excluding depreciation and amortization, interest expense, interest income, and income tax expenses. Adjusted EBITDA is defined as net income excluding depreciation and amortization, interest expense, interest income, income tax expenses and impairment loss on long-lived assets. We believe that gross billings, EBITDA and adjusted EBITDA provide valuable insight into the sales of our course packages and the performance of our business.

These non-GAAP financial measures should not be considered in isolation from, or as a substitute for, their respective most directly comparable financial measure prepared in accordance with GAAP. A reconciliation of the historical non-GAAP financial measures to their respective most directly comparable GAAP measure has been provided in the tables included below. Investors are encouraged to review the reconciliation of the historical non-GAAP financial measures to their respective most directly comparable GAAP financial measures. As gross billings, EBITDA and adjusted EBITDA have material limitations as analytical metrics and may not be calculated in the same manner by all companies, they may not be comparable to other similarly titled measures used by other companies. In light of the foregoing limitations, you should not consider gross billings, EBITDA and adjusted EBITDA as a substitute for, or superior to, their respective most directly comparable financial measures prepared in accordance with GAAP. We encourage investors and others to review the Group's financial information in its entirety and not rely on a single financial measure.

**Taxation**

***The Cayman Islands***

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

***Singapore***

Our subsidiary, Sunlands Online Education Singapore Pte. Ltd is incorporated in Singapore and are subject to Singapore Profits Tax on the taxable income as reported in its statutory financial statements adjusted in accordance with relevant Singapore tax laws. The profits earned by such Singapore entity will be taxed at 17%, with 75% of the first SGD$10,000 taxable income and 50% of the next SGD$190,000 taxable income are exempted from income tax.

***Hong Kong***

Our subsidiaries in Hong Kong are subject to a two-tiered income tax rate for taxable income earned in Hong Kong with effect from April 1, 2018. The first HK$2 million of profits earned by Hong Kong entities will be taxed at 8.25%, while the remaining profits will continue to be taxed at the existing 16.5% tax rate. In addition, to avoid abuse of the two-tiered income tax rate regime, each group of connected entities can nominate only one entity to benefit from the two-tiered income tax rate. Payments of dividends by our subsidiaries to the Group are not subject to withholding tax in Hong Kong.

***PRC***

------

Our subsidiaries and the VIEs and their subsidiaries in China are companies incorporated under PRC law and, as such, are subject to PRC enterprise income tax on their taxable income in accordance with the relevant PRC income tax laws. Pursuant to the PRC Enterprise Income Tax Law, or PRC EIT Law, a uniform 25% enterprise income tax rate is generally applicable to both foreign-invested enterprises and domestic enterprises, except where a special preferential rate applies. For example, the local tax bureau in Guangdong exempted 40% of the EIT based on the statutory tax rate of 25% for the enterprises located in certain autonomous regions from 2018 to 2035. Besides, from January 1, 2023 to December 31, 2027, subject to certain criteria, the portion of annual taxable income amount of a small profit enterprise shall be computed at a reduced rate of 25% as taxable income amount, and be subject to enterprise income tax at 20% tax rate.

The Group's services are subject to VAT at the rate of 6%, and sales of goods are calculated at 13% on revenue and paid after deducting input VAT on purchases for general-VAT-payer entities in accordance with tax rule, except that certain subsidiaries were subject to a simple VAT collection method at a rate of 3%.

As a Cayman Islands holding company, we may receive dividends from our PRC subsidiaries through Sunlands Online Education HK Limited. The PRC EIT Law and its implementing regulations provide that dividends paid by a PRC entity to a non-resident enterprise for income tax purposes is subject to PRC withholding tax at a rate of 10%, subject to reduction by an applicable tax treaty with China. Pursuant to the Arrangement between Mainland China and the Hong Kong Special Administrative Region for the Avoidance of Double Taxation and Tax Evasion on Income, the withholding tax rate in respect to the payment of dividends by a PRC enterprise to a Hong Kong enterprise may be reduced to 5% from a standard rate of 10% if the Hong Kong enterprise directly holds at least 25% of the PRC enterprise and certain other conditions are met. Pursuant to the Notice of the State Administration of Taxation on the Issues concerning the Application of the Dividend Clauses of Tax Agreements, or SAT Circular 81, a Hong Kong resident enterprise must meet the following conditions, among others, in order to apply the reduced withholding tax rate: (i) it must be a company; (ii) it must directly own the required percentage of equity interests and voting rights in the PRC resident enterprise; and (iii) it must have directly owned such required percentage in the PRC resident enterprise throughout the 12 months prior to receiving the dividends. The State Administration of Taxation promulgated the Administrative Measures for Non-resident Taxpayers to Enjoy Treatment under Treaties, or SAT Circular 35, which became effective on January 1, 2020. SAT Circular 35 provides that nonresident enterprises are not required to obtain pre-approval from the relevant tax authority in order to enjoy the reduced withholding tax. Instead, non-resident enterprises and their withholding agents may, by self-assessment and on confirmation that the prescribed criteria to enjoy the tax treaty benefits are met, directly apply the reduced withholding tax rate, and file necessary forms and supporting documents when performing tax filings, which will be subject to post-tax filing examinations by the relevant tax authorities. Accordingly, Sunlands Online Education HK Limited may be able to benefit from the 5% withholding tax rate for the dividends it receives from Wuhan Zhibo if it satisfies the conditions prescribed under SAT Circular 81 and other relevant tax rules and regulations. However, according to SAT Circular 81 and SAT Circular 35, if the relevant tax authorities consider the transactions or arrangements the Group has are for the primary purpose of enjoying a favorable tax treatment, the relevant tax authorities may adjust the favorable withholding tax in the future.

If our company or any of our subsidiaries outside of China were deemed to be a "resident enterprise" under the PRC EIT Law, it would be subject to enterprise income tax on its worldwide income at a rate of 25%. See "Item 3. Key Information—3.D. Risk Factors—Risks Related to Doing Business in China—If we are classified as a PRC resident enterprise for PRC enterprise income tax purposes, such classification could result in unfavorable tax consequences to the Group and our non-PRC shareholders and ADS holders."

**Critical Accounting Estimates**

We prepare financial statements in accordance with U.S. GAAP, which requires the Group to make judgments, estimates and assumptions that affect the reported amounts of our assets and liabilities and the disclosure of our contingent assets and liabilities at the end of each fiscal period and the reported amounts of revenues and expenses during each fiscal period. We continually evaluate these judgments and estimates based on our own historical experience, knowledge and assessment of current business and other conditions, our expectations regarding the future based on available information and assumptions that we believe to be reasonable, which together form our basis for making judgments about matters that are not readily apparent from other sources. Since the use of estimates is an integral component of the financial reporting process, the Group's actual results could differ from those estimates. Some of our accounting estimates require a higher degree of judgment than others in their application.

The selection of critical accounting estimates, the judgments and other uncertainties affecting application of those estimates and the sensitivity of reported results to changes in conditions and assumptions are factors that should be considered when reviewing the Group's financial statements. We believe the following accounting estimates involve the most significant judgments and estimates used in the preparation of the Group's financial statements. For further information on our critical accounting estimates, see Note 2 to the consolidated financial statements.

***Revenue recognition***

------

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

The Group's contracts with customers may include promises to transfer multiple services and goods. Determining whether different services and goods are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment.

For the year ended December 31, 2025, the Group derived revenue primarily from the online education services. Revenues for online education services are recognized on a straight-line basis over the service period from the registration day to the day on which the service period ends.

For online education services, the Group provides an integrated online education service package to students, including online live streaming audio-video interactive course content, recorded previous live audio-video course content, quiz banks, online chat rooms, and educational contents. The services and goods provided in the package are highly interdependent and interrelated in the context of the contract and are only considered accessory services to the online live streaming and recorded courses which are not distinct and are not sold standalone. Therefore, the Group's integrated online education services package is accounted for as a single performance obligation.

The transaction price of the integrated online education service package is determined by the contract amount net of any discount. Students are offered a full, unconditional refund within 24 hours upon enrollment and undelivered courses are eligible for refund during the entire service period, excluding registration fees. Refund liability represents the tuition fee collected by the Group which is expected to refund back to the customers as a result of the Group's refund policy. Refund liabilities are estimated based on a historical refund ratio on a portfolio basis using the expected value method and current period experience factors, such as the anticipated cash refund that would occur in the normal course of business. This may requires significant judgments and the actual amount of refund may differ from the Group's estimates.

**5. B. Liquidity and Capital Resources**

***Cash Flows and Working Capital***

The Group financed operations from cash generated from operating activities as well as proceeds from the issuance and sale of our ordinary shares. As of December 31, 2025, the Group had RMB575.7 million (US$82.3 million) in cash and cash equivalents, the majority of which were held by our company, our PRC subsidiaries, the VIEs and the VIEs' subsidiaries in China. The Group's cash and cash equivalents consist primarily of bank deposits and are primarily denominated in U.S. dollars and Renminbi. We believe that the Group's current cash and anticipated cash flow from operations will be sufficient to meet the Group's anticipated cash needs, including the cash needs for working capital and capital expenditures, for at least the next 12 months. As of December 31, 2025, the Group's cash and cash equivalents denominated in U.S. dollars and Renminbi amounted to RMB364.0 million (US$52.0 million) and RMB211.2 million (US$30.2 million), respectively. We believe there is no substantial doubt to operate as a going concern, as a result, the accompanying consolidated financial statements have been prepared on a going concern basis, and do not reflect any adjustments relating to the recoverability and reclassification of assets and liabilities that might have been necessary if we were unable to continue as a going concern.

The Group recorded net income of RMB640.8 million, RMB342.1 million and RMB365.6 million (US$52.3 million) for the years ended December 31, 2023, 2024 and 2025, respectively. The Group had positive working capital of RMB82.9 million and RMB157.9 million (US$22.6 million) as of December 31, 2024 and 2025, respectively.

We intend to finance the Group's future working capital requirements and capital expenditures from existing cash balance, cash generated from operating activities and funds raised from financing activities. We may, however, require additional cash due to changing business conditions or other future developments, including any investments or acquisitions we may decide to pursue. If our existing cash is insufficient to meet the Group's requirements, we may seek to issue debt or equity securities or obtain additional credit facilities. Financing may be unavailable in the amounts we need or on terms acceptable to us, if at all. Issuance of additional equity securities, including convertible debt securities, would dilute earnings per share. The incurrence of debt would divert cash for working capital and capital expenditures to service debt obligations and could result in operating and financial covenants that restrict the Group's operations and our ability to pay dividends to our shareholders. If we are unable to obtain additional equity or debt financing as required, the Group's business operations and prospects may suffer.

We did not have any off-balance sheet arrangements as of December 31, 2025.

As a holding company with no material operations of our own, the Group's operations are primarily conducted through our subsidiaries and the VIEs in China. We are permitted under PRC laws and regulations to provide funding to our PRC subsidiaries in China through capital contributions or loans, subject to the approval of government authorities and limits on the amount of capital contributions and loans. In addition, our subsidiaries in China may provide Renminbi funding to the VIEs only through entrusted loans. The ability of our subsidiaries in China to make dividends or other cash payments

------

to us is subject to various restrictions under PRC laws and regulations. See "Item 3. Key Information—3.D. Risk Factors—Risks Related to Doing Business in China—We may rely on dividends and other distributions on equity paid by our PRC and Hong Kong subsidiaries to fund any cash and financing requirements we may have, and any limitation on the ability of these subsidiaries in the PRC, including Hong Kong, to make payments to us could have a material and adverse effect on our ability to conduct the Group's business" and "Item 3. Key Information—3.D. Risk Factors—Risks Related to Doing Business in China—If we are classified as a PRC resident enterprise for PRC enterprise income tax purposes, such classification could result in unfavorable tax consequences to the Group and our non-PRC shareholders and ADS holders."

Liquidity and Capital Resources—Cash Flows and Working Capital" beginning on page 90 of our Form 20-F for the fiscal year ended December 31, 2023 filed with the Securities and Exchange Commission on April 25, 2024 (Securities Act File No. 001-38423).

***Operating Activities***

Net cash generated from operating activities was RMB146.8 million (US$21.0 million) in 2025. The difference between the Group's net income of RMB365.6 million (US$52.3 million), after netting non-cash reconciliation items, and the net cash used in operating activities was mainly due to (i) a decrease in deferred revenue of RMB331.2 million (US$47.4 million), (ii) a decrease in accrued expenses and other current liabilities of RMB38.4 million (US$5.5 million), (iii) a decrease in lease liability of RMB6.7 million (US$1.0 million); partially offset by (i) impairment loss on long-lived assets of RMB67.9 million (US$9.7 million), (ii) depreciation and amortization of RMB28.8 million (US$4.1 million), (iii) a decrease in deferred costs of RMB27.8 million (US$4.0 million), (iv) non-cash lease expenses of RMB12.2 million (US$1.7 million), (v) a decrease in prepaid expenses and other current assets of RMB12.4 million (US$1.8 million). Deferred revenue consisted primarily of tuition paid upfront by students at the time of purchase of course packages. Deferred cost consisted primarily of the incremental sales commissions and service fees relating to obtaining of customer contracts which is expected to be recovered and capitalized.

Net cash generated from operating activities was RMB195.5 million in 2024. The difference between the Group's net income of RMB342.1 million, after netting non-cash reconciliation items, and the net cash used in operating activities was mainly due to (i) a decrease in deferred revenue of RMB194.0 million, (ii) an increase in deferred tax assets of RMB24.7 million, (iii) a decrease in lease liability of RMB19.9 million; partially offset by (i) depreciation and amortization of RMB29.5 million, (ii) non-cash lease expenses of RMB18.1 million, (iii) a decrease in deferred costs of RMB18.1 million, (iv) loss from an equity method investment of RMB13.5 million. Deferred revenue consisted primarily of tuition paid upfront by students at the time of purchase of course packages. Deferred cost consisted primarily of the incremental sales commissions and service fees relating to obtaining of customer contracts which is expected to be recovered and capitalized.

***Investing Activities***

Net cash used in investing activities was RMB12.7 million (US$1.8 million) in 2025, which was primarily attributable to purchase of short-term investments of RMB1,491.4 million (US$213.3 million) and the payment for long-term investments of RMB84.6 million (US$12.1 million), partially offset by proceeds from maturity of short-term investments of RMB1,553.0 million (US$222.1 million) and proceeds received from disposal of long-term investments of RMB6.9 million (US$1.0 million).

Net cash used in investing activities was RMB358.9 million in 2024, which was primarily attributable to purchase of short-term investments of RMB1,738.7 million and the purchase of long-term investments of RMB235.3 million, partially offset by proceeds from maturity of short-term investments of RMB1,607.1 million.

------

***Financing Activities***

Net cash used in financing activities in 2025 was RMB47.7 million (US$6.8 million), which was primarily attributable to repayment of bank debt of RMB61.5 million (US$8.8 million), and partially offset by the proceeds from bank loans of RMB20.0 million (US$2.9 million).

Net cash used in financing activities in 2024 was RMB112.7 million, which was primarily attributable to repayment of bank debt of RMB101.8 million and repurchase Class A ordinary shares of RMB10.9 million.

***Material Cash Requirements*** 

The Group's material cash requirements as of December 31, 2025 and any subsequent interim period primarily include the Group's operating lease commitments, capital expenditures and working capital requirements.

The Group's operating lease commitments consist of the commitments under the lease agreements for office premises. The Group leases the office facilities under non-cancelable operating leases with various expiration dates. The majority of the Group's operating lease commitments are related to our office lease agreements in China.

The following table sets forth the Group's contractual obligations as of December 31, 2025:

---

The Group's capital expenditures are incurred primarily in connection with purchases of IT infrastructure equipment necessary to support the Group's operations. The Group's capital expenditures were RMB6.4 million, RMB0.4 million and RMB0.7 million (US$0.1 million), respectively, for the years ended December 31, 2023, 2024 and 2025. We intend to fund our future working capital requirements and capital expenditures from the Group's existing cash balance, cash generated from operating activities and funds raised from financing activities.

The Group's long-term loans represent future maximum commitment relating to the principal amount and interests in connection with two loan agreements dated August 29, 2018 and November 21, 2018 in the aggregate principal amount of RMB260.0 million (US$40.8 million) and one loan agreement dated July 5, 2021 with the principal amount of RMB61.5 million (US$9.7 million). The annual interest rate for the loan agreements dated in 2018 was 1.472% prior to April 15, 2021, 1.25% from April 16, 2021 to August 25, 2023 and 0.7% after August 25, 2023 on top of base rate of one-year interest rate released by the People's Bank of China. The annual interest rate for the loan agreement dated in 2021 was 1.05% prior to July 1, 2022 and 0.75% after July 1, 2022 on top of base rate of one-year interest rate released by the People's Bank of China. Under the agreements, the Group is obligated to repay the loans in equal installment every three months with maturity terms ranging from eight years to ten years. The Group repaid RMB38.7 million, RMB101.8 million and RMB41.5 million (US$5.9 million) for the principals of loans during the years ended December 31, 2023, 2024 and 2025, respectively. During the year ended December 31, 2024, the Group has fully repaid outstanding amount under the two loan agreements dated August 29, 2018 and November 21, 2018.

During the year ended December 31, 2025, the Group had fully repaid outstanding loan principals before maturity date for the loan dated July 5, 2021.

The Group has not entered into any financial guarantees or other commitments to guarantee the payment obligations of any third parties. The Group does not have retained or contingent interests in assets transferred. The Group has not entered into contractual arrangements that support the credit, liquidity or market risk for transferred assets. The Group does not have obligations that arise or could arise from variable interests held in an unconsolidated entity, or obligations related to derivative instruments that are both indexed to and classified in the Group's own equity, or not reflected in the statement of financial position.

Other than those shown above, the Group did not have any significant capital and other commitments, long-term obligations, or guarantees as of December 31, 2025.

**Transfer of Funds and Other Assets**

Under relevant PRC laws and regulations, we are permitted to remit funds to the VIEs through loans rather than capital contributions. The VIEs funded their operations primarily using cash generated from operating and financing activities. In addition, we and the VIEs may, from time to time, lend cash to each other to settle the payment obligations on each other's behalf to provide temporary working capital support. In 2023 and 2024, the net amounts of working capital support provided by the VIEs to our PRC subsidiaries were RMB602.9 million and RMB924.6 million, respectively. In 2025, the net amounts of working capital support provided by our PRC subsidiaries to the VIEs were RMB148.4 million (US$21.2

------

million). For more information, see "Item 3. Key Information—Condensed Consolidating Schedule," and consolidated financial statements included elsewhere in this annual report.

As of December 31, 2025, Sunlands Technology Group had made cumulative capital contributions of US$200.2 million to our PRC subsidiaries through an intermediate holding company. These funds have been used by our PRC subsidiaries for their operations. Our PRC subsidiaries maintained certain personnel for sales and marketing, research and development, and general and administrative functions to support the operations of the VIEs.

In 2023, 2024 and 2025, the VIEs transferred RMB26.8 million, RMB60.1 million and RMB132.6 million (US$19.0 million) of service fees to our PRC subsidiaries pursuant to the contractual arrangements, respectively. The outstanding balance of service fees owed by the VIEs to our PRC subsidiaries was nil as of each of December 31, 2023, 2024 and 2025. There were no other assets transferred between us and the VIEs in 2023, 2024 and 2025.

As advised by our PRC legal counsel, for any amounts owed by the VIEs to our PRC subsidiaries under the VIE agreements, unless otherwise required by PRC tax authorities, the Group is able to settle such amounts without limitations under the current effective PRC laws and regulations, provided that the VIEs have sufficient funds to do so and that the VIEs, in case in the form of non-enterprise institution, follow the principles of openness, fairness and impartiality, fix the price reasonably and regulate the decision-making, and do not damage the state interests, the interests of the non-enterprise institution or the rights and interests of the teachers and students when conducting such related party transaction.

Our subsidiaries are permitted to pay dividends to their shareholders, and eventually to Sunlands Technology Group, only out of their retained earnings, if any, as determined in accordance with PRC accounting standards and regulations. Such payment of dividends by entities registered in China is subject to limitations, which could result in limitations on the availability of cash to fund dividends or make distributions to shareholders of our securities. For example, our PRC subsidiaries and the VIEs are required to make appropriations to certain statutory reserve funds or may make appropriations to certain discretionary funds, which are not distributable as cash dividends except in the event of a solvent liquidation of the companies. For more details, see "Item 3. Key Information—D. Risk Factors—Risks Related to Doing Business in China—We may rely on dividends and other distributions on equity paid by our PRC and Hong Kong subsidiaries to fund any cash and financing requirements we may have, and any limitation on the ability of these subsidiaries in the PRC, including Hong Kong, to make payments to us could have a material and adverse effect on our ability to conduct the Group's business."

Sunlands Technology Group has previously declared a special cash dividend of US$1.36 per ordinary share (or US$0.68 per ADS) to holders of its ordinary shares and ADSs on June 14, 2022, which had been fully paid. 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 the Group's business. See "Item 8. Financial Information—8.A. Consolidated Statements and Other Financial Information—Dividend Policy."

As of the date of this annual report, no transfers, dividends, or distributions between Sunlands Technology Group, our PRC subsidiaries, and the VIEs, other than those described in this annual report, have been made. As of the date of this annual report, we do not have cash management policies in place that dictate how funds are transferred between Sunlands Technology Group, our subsidiaries, the VIEs and the investors. Rather, the funds can be transferred in accordance with the applicable laws and regulations discussed in this section.

To the extent cash or assets in the business are in the PRC, including Hong Kong, or a PRC (including Hong Kong) entity, the funds or assets may not be available to fund operations or for other use outside of the PRC or Hong Kong due to interventions in or the imposition of restrictions and limitations on the ability of Sunlands Technology Group, our subsidiaries, or the VIEs by the PRC government to transfer cash or assets. There is no assurance the PRC government will not intervene in or impose restrictions on the ability of Sunlands Technology Group, our subsidiaries, or the VIEs to transfer cash or assets. See "Item 3. Key Information—3.D. Risk Factors—Risks Related to Doing Business in China—We may rely on dividends and other distributions on equity paid by our PRC and Hong Kong subsidiaries to fund any cash and financing requirements we may have, and any limitation on the ability of these subsidiaries in the PRC, including Hong Kong, to make payments to us could have a material and adverse effect on our ability to conduct the Group's business."

For the purpose of illustration, the below table reflects the hypothetical taxes that might be required to be paid within China, assuming that: (i) we have taxable earnings, and (ii) we determine to pay a dividend in the future:

------

---

| | |
|:---|:---|
|  | **Taxation<br>Scenario**<sup>(1)</sup>**<br>Statutory Tax<br>and<br>Standard Rates** |
| Hypothetical pre-tax earnings<sup>(2)</sup> | 100% |
| Tax on earnings at statutory rate of 25%<sup>(3)</sup> | (25)% |
| Net earnings available for distribution | 75% |
| Withholding tax at standard rate of 10%<sup>(4)</sup> | (7.5)% |
| Net distribution to Parent/Shareholders | 67.5% |

---

Notes:

(1) The tax calculation has been simplified for the purpose of this example. The hypothetical book pre-tax earnings amount, which does not consider timing differences, is assumed to equal the taxable income in the PRC.

(2) Under the terms of the VIE agreements, sales service fees are charged by our PRC subsidiaries to the VIEs. For all the periods presented, these fees are recognized as cost of revenues of the VIEs, with a corresponding amount as service income by our PRC subsidiaries and eliminated in consolidation. For income tax purposes, our PRC subsidiaries and the VIEs file income taxes on a separate company basis. The fees paid are recognized as a tax deduction by the VIEs and as income by our PRC subsidiaries and are tax neutral.

(3) Certain of our subsidiaries qualifies for a 15% preferential income tax rate in China. However, such rate is temporary in nature, and may not be available in a future period. For purposes of this hypothetical example, the table above reflects a maximum tax scenario under which the full statutory rate would be effective.

(4) Upon the instance that the VIEs reach a cumulative level of profitability, because our PRC subsidiaries occupy certain trademarks and copyrights, the agreements will be updated to reflect charges for such trademarks and copyrights usage on the basis that they will qualify for tax neutral treatment.

China's Enterprise Income Tax Law imposes a withholding income tax of 10% on dividends distributed by a Foreign Invested Enterprises, or the FIE, to its immediate holding company outside of China. A lower withholding income tax rate of 5% is applied if the FIE's immediate holding company is registered in Hong Kong or other jurisdictions that have a tax treaty arrangement with China, subject to a qualification review at the time of the distribution. For the purpose of this hypothetical example, this table has been prepared based on a taxation scenario under which the full withholding tax would be applied. In addition, this table has been prepared under the assumption that all profits of the VIEs will be distributed as fees to our PRC subsidiaries under tax neutral contractual arrangements. If in the future, the accumulated earnings of the VIEs exceed the fees paid to our PRC subsidiaries, or if the current and contemplated fee structure between the intercompany entities is determined to be non-substantive and disallowed by Chinese tax authorities, we have other tax-planning strategies that can be deployed on a tax neutral basis. Should all tax planning strategies fail, the VIEs could, as a matter of last resort, make a non-deductible transfer to our PRC subsidiaries for the amounts of the stranded cash in the VIEs. This would result in the double taxation of earnings: one at the VIE level (for non-deductible expenses) and one at the PRC subsidiary level (for presumptive earnings on the transfer). Such a transfer and the related tax burdens would reduce our after-tax income to approximately 50.6% of the pre-tax income. The Group's management is of the view that the likelihood that this scenario would happen is remote.

**Holding Company Structure**

Sunlands Technology Group is a holding company with no material operations of its own. The Group's operations are primarily conducted through our subsidiaries and the VIEs in China. As a result, our ability to pay dividends depends upon dividends paid by our subsidiaries. If our subsidiaries or any newly formed subsidiaries incur debt on their own behalf in the future, the instruments governing their debt may restrict their ability to pay dividends to us.

In addition, our subsidiaries in China are permitted to pay dividends to us only out of their retained earnings, if any, as determined in accordance with the Accounting Standards for Business Enterprise as promulgated by the Ministry of Finance of the PRC, or PRC GAAP. In accordance with PRC company laws, the VIEs in China must make appropriations from their after-tax profit to non-distributable reserve funds including (i) statutory surplus fund and (ii) discretionary surplus fund. The appropriation to the statutory surplus fund must be at least 10% of the after-tax profits calculated in accordance with PRC GAAP. Appropriation is not required if the statutory surplus fund has reached 50% of the registered capital of the VIEs. Appropriation to discretionary surplus fund is made at the discretion of the VIEs. Pursuant to the law applicable to China's foreign investment enterprise, our subsidiaries that are foreign investment enterprise in the PRC have to make appropriation from their after-tax profits, as determined under PRC GAAP, to reserve funds including (i) general reserve fund, (ii) enterprise expansion fund and (iii) staff bonus and welfare fund. The appropriation to the general reserve fund must be at least 10% of the after-tax profits calculated in accordance with PRC GAAP. Appropriation is not required if the reserve fund has reached 50% of the registered capital of our subsidiary. Appropriation to the other two reserve funds are at our subsidiary's discretion.

As a Cayman Islands holding company, we are permitted under PRC laws and regulations to provide funding from the proceeds of our fund raising activities to our PRC subsidiaries only through loans or capital contributions, and to the VIEs only through loans, in each case subject to the satisfaction of the applicable government registration and reporting, approval requirements. As a result, there is uncertainty with respect to our ability to provide prompt financial support to our PRC subsidiaries and the VIEs when needed. Notwithstanding the foregoing, our PRC subsidiaries may use their own retained

------

earnings (rather than Renminbi converted from foreign currency denominated capital) to provide financial support to the VIEs either through entrustment loans from our PRC subsidiaries to the VIEs or direct loans to the VIEs' nominee shareholders, which would be contributed to the VIEs as capital injections. Such direct loans to the nominee shareholders would be eliminated in the Group's consolidated financial statements against the VIEs' share capital.

**5. C. Research and Development, Patents and Licenses, etc.**

The Group has focused on and will continue to invest in the technology system, which supports all key aspects of the Group's online platform and is designed to optimize for scalability and flexibility. See "Item 4. Information on the Company—4.B. Business Overview."

For details of the Group's material licenses and approvals, see "Item 4. Information on the Company—4.B. Business Overview—Licenses and Approvals."

**5. D.Trend Information**

Other than as disclosed elsewhere in this annual report, we are not aware of any trends, uncertainties, demands, commitments or events for the year ended December 31, 2025 that are reasonably likely to have a material and adverse effect on our net revenues, income, profitability, liquidity or capital resources, or that would cause the disclosed financial information to be not necessarily indicative of future results of operations or financial condition.

**5. E. Critical Accounting Estimates**

For our critical accounting estimates, see "Item 5. Operating and Financial Review and Prospects—5.A. Operating Results—Critical Accounting Estimates."

Specifically, each executive officer has agreed not to (i) carry out or otherwise be concerned or interested, directly or indirectly, in certain businesses in direct or indirect competition with us; (ii) assume employment with or provide services to certain of our competitors or engage, whether as principal, partner, licensor or otherwise, with such competitors; or (iii) seek directly or indirectly, by the offer of alternative employment or other inducement whatsoever, to solicit the services of any of our employees, agents or consultants who are employed or engaged by us at any time in the one year preceding the last date of his or her employment.

**6. B. Compensation**

**Compensation of Directors and Senior Management**

For the fiscal year ended December 31, 2025, we paid an aggregate of RMB1.8 million (US$0.3 million) in cash to our executive officers. The payment of compensation to our independent directors for their services rendered for the year ended December 31, 2025 is in a total amount of RMB0.9 million (US$0.1 million), which has been fully paid in cash. For share incentive grants to our directors and executive officers, see "—Share Incentive Plan." We do not set aside any amount to provide pension, retirement or similar benefits.

**Share Incentive Plan**

**2017 Plan**

We adopted an employee share incentive plan in October 2017, or the 2017 Plan. The purpose of the 2017 Plan is to attract and retain exceptionally qualified personnel and to encourage them to acquire a proprietary interest in our growth and performance.

As of the date of this annual report, we are authorized to grant options or share purchase rights to purchase up to an aggregate of 58,049 ordinary shares under the 2017 Plan. As of the same date, options to purchase an aggregate number of

------

31,550 ordinary shares are outstanding, all of which had vested and become exercisable.

The following paragraphs summarize the terms of the 2017 Plan.

***Types of Awards***. The 2017 Plan permits the awards of options, share appreciation rights, rights to dividends and dividend equivalent right, restricted shares and restricted share units and other rights or benefits under the 2017 Plan.

***Plan Administration***. A committee formed in accordance with applicable stock exchange rules shall administer the 2017 Plan, unless otherwise determined by the board of directors.

***Eligibility***. Our employees and consultants are eligible to participate in the 2017 Plan. An employee or consultant who has been granted an award may, if he or she is otherwise eligible, be granted additional awards.

***Designation of Award***. Each award under the 2017 Plan is designated in an award agreement, which is a written agreement evidencing the grant of an award executed by the company and the grantee, including any amendments thereto.

***Conditions of Award***. The board of directors or any entity appointed by the board of directors to administer the 2017 Plan shall determine the provisions, terms, and conditions of each award including, but not limited to, the award vesting schedule, repurchase provisions, rights of first refusal, forfeiture provisions, and form of payment upon settlement of the award.

***Terms of Award***. The term of each award is stated in the award agreement between the company and the grantee of such award.

***Transfer Restrictions***. Unless otherwise determined by the administrator of the 2017 Plan, no award and no right under any such award, shall be assignable, alienable, saleable or transferable by the employee otherwise than by will or by the laws of descent and distribution unless, if so determined by the administrator of the 2017 Plan, the employee may, in the manner established by such administrator, designate a beneficiary or beneficiaries to exercise the rights of the employee, and to receive any property distributable, with respect to any award upon the death of the employee.

***Exercise of Award***. Any award granted under the 2017 Plan is exercisable at such times and under such conditions as determined by the administrator under the terms of the 2017 Plan and specified in the award agreement. An award is deemed to be exercised when exercise notice has been given to the company in accordance with the terms of the award by the person entitled to exercise the award and full payment for the shares with respect to which the award is exercised.

***Amendment, Suspension or Termination of the 2017 Plan***. The administrator of the 2017 Plan may amend, alter, suspend, discontinue or terminate this 2017 Plan, or any award agreement hereunder or any portion hereof or thereof at any time; *provided*, *however*, that no such amendment, alteration, suspension, discontinuation or termination shall be made without (i) shareholder approval with such legally mandated threshold for a resolution of the shareholders if such approval is necessary to comply with any tax or regulatory requirement for which or with which the administrator of the 2017 Plan deems it necessary or desirable to qualify or (ii) comply shareholder approval with such threshold for a resolution of the shareholders in respect of such amendment, alteration, suspension, discontinuation or termination as provided in our memorandum and articles of association for any amendment to the 2017 Plan that increases the total number of shares reserved for the purposes of the 2017 Plan, and (iii) with respect to any award agreement, the consent of the affected employee, if such action would materially and adversely affect the rights of such employee under any outstanding award.

As of the date of this annual report, there were no outstanding equity awards granted to our directors and executive officers under the 2017 Plan. As of the same date, our other employees and certain former employees as a group held options to purchase 31,550 Class C ordinary shares, with an exercise price of US$84.75 per share.

For discussions of our accounting estimates for awards granted pursuant to the 2017 Plan, see Note 2 to our consolidated financial statements.

**6. C. Board Practices** 

**Board of Directors**

Our board of directors consists of six directors, including two independent directors, namely Mr. Zheng Zhao and Mr. Yingda Song. A director is not required to hold any shares in our company to qualify to serve as a director. The Corporate Governance Rules of the NYSE generally require that a majority of an issuer's board of directors must consist of independent directors. However, the Corporate Governance Rules of the NYSE permit foreign private issuers like us to follow "home country practice" in certain corporate governance matters. We rely on this "home country practice" exception and do not have a majority of independent directors serving on our board of directors.

A director who to his knowledge is in any way, whether directly or indirectly, interested in a contract or arrangement or proposed contract or arrangement with our company is required to declare the nature of his or her interest at a meeting of our directors. A general notice given to the directors by any director to the effect that (i) he is a member or officer of any specified company or firm and is to be regarded as interested in any contract or transaction with that company or firm, or (ii) he is to be regarded as interested in any contract or transaction which may, after the date of such notice, be made with a specified person who is connected with him, shall be deemed a sufficient declaration of interest for the purposes of

------

voting on a resolution in respect to a contract or transaction in which he/she has an interest. A director may vote in respect of any contract or proposed contract or arrangement notwithstanding that he may be interested therein and if he does so, his vote shall be counted and he may be counted in the quorum at any meeting of the directors at which any such contract or proposed contract or arrangement is considered, subject to any separate requirement for Audit Committee approval under applicable laws or the rules of the New York Stock Exchange, and unless disqualified by the chairman of the relevant board meeting. Our board of directors may exercise all of the powers of our company to borrow money, to mortgage or charge its undertaking, property and assets (present and future) and uncalled capital, and to issue debentures, bonds and other securities whenever money is borrowed or as security for any debt, liability or obligation of our company or of any third party. None of our directors has a service contract with us that provides for benefits upon termination of service as a director.

**Committees of the Board of Directors** 

We have established an audit committee, a compensation committee and a nominating and corporate governance committee under our board of directors. We have adopted a charter for each of the three committees. Each committee's members and functions are described below.

***Audit Committee***

Our audit committee consists of Mr. Zheng Zhao and Mr. Yingda Song, and is chaired by Mr. Zheng Zhao. We have determined that each of Mr. Zheng Zhao and Mr. Yingda Song satisfies the requirements of Section 303A of the Corporate Governance Rules of the NYSE and meet the independence standards under Rule 10A-3 under the Securities Exchange Act of 1934, as amended. We have determined that Mr. Zheng Zhao qualifies as an "audit committee financial expert." The audit committee oversees our accounting and financial reporting processes and the audits of the Group's financial statements. The audit committee is also responsible for, among other things:

&nbsp;&nbsp;&nbsp;&nbsp;•reviewing and recommending to our board for approval, the appointment, re-appointment or removal of the independent auditor;

&nbsp;&nbsp;&nbsp;&nbsp;•approving the remuneration and terms of engagement of the independent auditor and pre-approving all auditing and non-auditing services performed by our independent auditors;

&nbsp;&nbsp;&nbsp;&nbsp;•obtaining and reviewing a written report from our independent auditor describing matters relating to its independence and quality control procedures;

&nbsp;&nbsp;&nbsp;&nbsp;•discussing with the independent registered public accounting firm any audit problems or difficulties and any significant disagreements with the management;

&nbsp;&nbsp;&nbsp;&nbsp;•reviewing and approving all proposed related party transactions, as defined in Item 404 of Regulation S-K under the Securities Act;

&nbsp;&nbsp;&nbsp;&nbsp;•discussing the annual audited financial statements with management and the independent registered public accounting firm;

&nbsp;&nbsp;&nbsp;&nbsp;•reviewing the adequacy and effectiveness of our accounting and internal control policies and procedures;

&nbsp;&nbsp;&nbsp;&nbsp;•reviewing and reassessing the adequacy of the committee charter;

&nbsp;&nbsp;&nbsp;&nbsp;•at least annually, evaluating the performance, responsibilities, budget and staffing of our internal audit function and review and approve the internal audit plan;

&nbsp;&nbsp;&nbsp;&nbsp;•overseeing compliance with our code of business conduct and ethics and reporting on such compliance to our board of directors; and

&nbsp;&nbsp;&nbsp;&nbsp;•reporting regularly to our board of directors.

***Compensation Committee***

Our compensation committee consists of Mr. Peng Ou, Mr. Tongbo Liu and Mr. Zheng Zhao, and is chaired by Mr. Peng Ou. We have determined that Mr. Zheng Zhao satisfies the "independence" requirements of Section 303A of the Corporate Governance Rules of the NYSE. The compensation committee assists our board of directors in reviewing and approving the compensation structure, including all forms of compensation, relating to our directors and executive officers. The compensation committee is also responsible for, among other things:

&nbsp;&nbsp;&nbsp;&nbsp;•reviewing and approving the compensation of our chief executive officer and each of our other executive officers;

&nbsp;&nbsp;&nbsp;&nbsp;•in consultation with our chief executive officer, periodically reviewing our management succession planning;

&nbsp;&nbsp;&nbsp;&nbsp;•reviewing and evaluating our executive compensation and benefits policies generally (subject, if applicable, to shareholder approval), including the review and recommendation of any incentive-compensation and equity-based

------

plans that are subject to the approval of our board of directors;

&nbsp;&nbsp;&nbsp;&nbsp;•reviewing and reassessing the adequacy of the committee charter;

&nbsp;&nbsp;&nbsp;&nbsp;•selecting compensation consultant, legal counsel or other adviser only after taking into consideration all factors relevant to that person's independence from management; and

&nbsp;&nbsp;&nbsp;&nbsp;•reporting regularly to our board of directors.

***Nominating and Corporate Governance Committee***

Our nominating and corporate governance committee consists of Mr. Peng Ou, Mr. Tongbo Liu and Mr. Zheng Zhao, and is chaired by Mr. Peng Ou. We have determined that Mr. Zheng Zhao satisfies the "independence" requirements of Section 303A of the Corporate Governance Rules of the NYSE. The nominating and corporate governance committee assists our board of directors in selecting individuals qualified to become our directors and in determining the composition of our board of directors and its committees. The nominating and corporate governance committee is also responsible for, among other things:

&nbsp;&nbsp;&nbsp;&nbsp;•overseeing searches for and identify qualified individuals for membership on our board of directors;

&nbsp;&nbsp;&nbsp;&nbsp;•recommending to our board of directors criteria for membership on our board of directors and its committees and recommending individuals for membership on our board of directors and its committees;

&nbsp;&nbsp;&nbsp;&nbsp;•at least annually, leading our board of directors in a self-evaluation to determine whether it and its committees are functioning effectively;

&nbsp;&nbsp;&nbsp;&nbsp;•at least annually, reviewing the evaluations prepared by each board committee of such committee's performance and consider any recommendations for proposed changes to our board of directors;

&nbsp;&nbsp;&nbsp;&nbsp;•reviewing and approving compensation (including equity-based compensation) for our directors;

&nbsp;&nbsp;&nbsp;&nbsp;•overseeing an orientation and continuing education program for directors;

&nbsp;&nbsp;&nbsp;&nbsp;•reviewing and reassessing the adequacy of the committee charter; and

&nbsp;&nbsp;&nbsp;&nbsp;•reporting regularly to our board of directors.

**Duties and Functions of Directors**

Under Cayman Islands law, our directors owe fiduciary duties to our company, including a duty of loyalty, a duty to act honestly and a duty to act in what they consider in good faith to be in our best interests. Our directors must also exercise their powers only for a proper purpose. Our directors also owe to our company a duty to exercise the skill they actually possess and such care and diligence that a reasonable prudent person would exercise in comparable circumstances. It was previously considered that a director need not exhibit in the performance of his duties a greater degree of skill than may reasonably be expected from a person of his knowledge and experience. However, English and Commonwealth courts have moved towards an objective standard with regard to the required skill and care and these authorities are likely to be followed in the Cayman Islands. In fulfilling their duty of care to us, our directors must ensure compliance with our memorandum and articles of association, as amended and restated from time to time. Our company has the right to seek damages if a duty owed by our directors is breached. In limited exceptional circumstances, a shareholder may have the right to seek damages in our name if a duty owed by our directors is breached. The functions and powers of our board of directors include, among others, (i) convening shareholders' annual general meetings and reporting its work to shareholders at such meetings, (ii) declaring dividends, (iii) appointing officers and determining their terms of offices and responsibilities, and (iv) approving the transfer of shares of our company, including the registering of such shares in our share register.

**6. D. Employees** 

The Group had 2,113, 2,071 and 1,567 full-time employees as of December 31, 2023, 2024 and 2025, respectively. The decrease in the number of full-time employees was mainly driven by the strategic contraction of the business. As of December 31, 2025, most of the Group's employees were in Beijing, Guangzhou and Wuhan.

The following table sets forth the number of the Group's employees as of December 31, 2025:

---

| | | |
|:---|:---|:---|
| **Function** | **Number of<br>Full-Time<br>Employees** | **Percentages** |
| Academic and administrative faculty<sup>(1)</sup> | 148 | 9.4% |
| Sales and marketing staff | 874 | 55.8% |
| Sales operation | 277 | 17.7% |
| General and administrative | 153 | 9.8% |
| Technology development | 115 | 7.3% |
| **Total** | **1567** | **100.0%** |

---

Note:

(1) Consists of teachers, mentors, course and educational content development professionals, and other administrative faculty members.

The Group enters into employment contracts with full-time employees which contain standard confidentiality and non-compete provisions. In addition to salaries and benefits, we provide performance-based bonuses for full-time employees and commission-based compensation for the sales and marketing force.

Under PRC law, the Group participates in various employee social security plans that are organized by municipal and provincial governments for PRC-based full-time employees, including pension, unemployment insurance, childbirth insurance, work-related injury insurance, medical insurance and housing insurance. The Group is required under PRC law to make contributions from time to time to employee benefit plans for PRC-based full-time employees at specified percentages of the salaries, bonuses and certain allowances of such employees, up to a maximum amount specified by the local governments in China.

We believe that the Group maintains a good working relationship with our employees, and the Group has not experienced any material labor disputes in the past. None of the Group's employees are represented by labor unions.

**6. E. Share Ownership**

The following table sets forth information concerning the beneficial ownership of our ordinary shares as of March 31, 2026 by:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•each of our directors and executive officers; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•each person known to the Group to beneficially own more than 5% of each class of our ordinary shares.

The calculations in the table below are based on 6,696,498 issued and outstanding ordinary shares as of March 31, 2026, comprising (i) 2,538,047 Class A ordinary shares (excluding 5,200 Class A ordinary shares issued to our depositary bank for bulk issuance of ADSs reserved for future issuances upon the exercise or vesting of awards under our share incentive plans), (ii) 826,389 Class B ordinary shares, and (iii) 3,332,062 Class C ordinary shares.

Beneficial ownership is determined in accordance with the rules and regulations of the SEC. In computing the number of shares beneficially owned by a person and the percentage ownership of that person, we have included shares that the person has the right to acquire within 60 days, including through the exercise of any option, warrant, or other right or the conversion of any other security. These shares, however, are not included in the computation of the percentage ownership of any other person.

To our knowledge, as of March 31, 2026, 2,122,594 of our Class A ordinary shares were held by one record holder in the United States, which was the Bank of New York Mellon, the depositary of our ADR program. The number of beneficial owners of the ADSs in the United States is likely to be much larger than the number of record holders of our ordinary shares in the United States.

We are not aware of any arrangement that may, at a subsequent date, result in a change of control of our company.

**ITEM 8. FINANCIAL INFORMATION**

**8. A. Consolidated Statements and Other Financial Information**

We have appended consolidated financial statements filed as part of this annual report on Form 20-F.

**Legal Proceedings**

From time to time, the Group may become a party to various legal or administrative proceedings arising in the ordinary course of the Group's business. As of the date of this annual report, the Group is not a party to, and the Group is not aware of any threat of, any legal or administrative proceedings that, in the opinion of the management, are likely to have any material and adverse effect on the Group's business, financial condition, cash flow or results of operations.

In June 2019, we, and certain of our current and former directors and officers and our underwriters in our initial public offering were named as defendants in a securities class action filed in the U.S. District Court for the Eastern District of New York. An amended complaint in this class action was filed in November 2019. The action, purportedly brought on behalf of a class of persons who allegedly suffered damages as a result of their trading in the ADSs, alleges that our registration statement on Form F-1 in connection with our March 2018 initial public offering contains materially false and misleading statements and omissions in violation of the U.S. federal securities laws. We filed a motion to dismiss the action in March 2020, which was denied by an order dated March 31, 2021. In July 2021, we filed a motion for judgment on the pleadings, which was denied on September 21, 2022. On May 8, 2023, the parties entered into a stipulation of settlement to resolve the action on a class-wide basis without any admission of liability. The settlement received final approval of the court on October 11, 2023. For risks and uncertainties relating to pending cases against us, see "Item 3. Key Information—3.D. Risk Factors—Risks Related to the Group's Business—The Group may be subject to litigations, allegations, complaints and investigations from time to time arising out of business operations. We and certain of our directors and officers have been named as defendants in a shareholder class action lawsuit, which could have a material adverse impact on the Group's business, financial condition, results of operation, cash flows and reputation."

**Dividend Policy**

------

We currently do not have any dividend policy. On June 14, 2022, our board of directors declared a special cash dividend of US$1.36 per ordinary share (or US$0.68 per ADS) to holders of our ordinary shares and ADSs, which had been fully paid. 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 the Group's business.

We are an exempted 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 "Item 4. Information on the Company—4.B. Business Overview—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. Under Cayman Islands law, a Cayman Islands company may pay a dividend out of either profit or share premium account, provided that in no circumstances may a dividend be paid if this would result in the company being unable to pay its debts as they fall due in the ordinary course of business. Even if our board of directors decides to pay dividends, the form, frequency and amount will depend upon our future operations and earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that the board of directors may deem relevant. If we pay any dividends on our ordinary shares, we will pay those dividends which are payable in respect of the Class A ordinary shares underlying the ADSs to the depositary, as the registered holder of such Class A ordinary shares, and the depositary then will pay such amounts to the ADS holders in proportion to the Class A ordinary shares underlying the ADSs held by such ADS holders, subject to the terms of the deposit agreement, including the fees and expenses payable thereunder.

***General.*** Our authorized share capital is US$50,000 divided into 1,000,000,000 shares with a par value of US$0.00005 each, comprising (i) 796,062,195 Class A ordinary shares with a par value of US$0.00005 each, (ii) 826,389 Class B ordinary shares with a par value of US$0.00005 each, and (iii) 203,111,416 Class C ordinary shares with a par value of US$0.00005 each. Holders of ordinary shares have the same rights except for voting and conversion rights as set out in our fourth amended and restated memorandum and articles of association. All of our issued and outstanding ordinary shares are fully paid and non-assessable. Certificates representing the ordinary shares are issued in registered form. We may not issue share to bearer. Our shareholders who are non-residents of the Cayman Islands may freely hold and transfer their ordinary shares.

***Dividends.*** The holders of our ordinary shares are entitled to such dividends as may be declared by our board of directors subject to our fourth amended and restated memorandum and articles of association and the Companies Act. Our fourth amended and restated memorandum and articles of association provide that dividends may be declared and paid out of our profits, realized or unrealized. Dividends may also be declared and paid out of share premium account or any other fund or account which can be authorized for this purpose in accordance with the Companies Act.

***Voting Rights.*** In respect of all matters subject to shareholder vote, 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.

A quorum required for a meeting of shareholders consists of a majority of the votes attaching to the issued and outstanding shares entitled to vote at general meetings present in person or by proxy or, if a corporation or other non-natural person, by its duly authorized representative. As a Cayman Islands exempted company, we are not obliged by the Companies Act to call shareholders' annual general meetings. Our fourth amended and restated memorandum and articles of association provide that we may (but are not obliged to) in each year hold a general meeting as our annual general meeting in which case we will specify the meeting as such in the notices calling it, and the annual general meeting will be held at such time and place as may be determined by our directors. We, however, will hold an annual shareholders' meeting during each fiscal year, as required by the Listing Rules at the NYSE. Each general meeting, other than an annual general meeting, shall be an extraordinary general meeting. Shareholders' annual general meetings and any other general meetings of our shareholders may be called by a majority of our board of directors or our chairman and a majority of our board of directors or our chairman shall, upon requisition of shareholders holding not less 10% of all votes attaching to all issued and outstanding ordinary shares entitled to vote at general meetings, convene an extraordinary general meeting; however, our fourth amended and restated memorandum and articles of association do not provide our shareholders with any right to put any proposals before annual general meetings or extraordinary general meetings not called by such shareholders. Advance notice of at least fifteen (15) days is required for the convening of our annual general meeting and other general meetings unless such notice is waived in accordance with our articles of association.

An ordinary resolution to be passed at a meeting by the shareholders requires the affirmative vote of a simple majority of the votes attaching to the ordinary shares cast by those shareholders entitled to vote who are present in person or by proxy at a general meeting, while a special resolution also requires the affirmative vote of no less than two-thirds of the votes attaching to the ordinary shares cast by those shareholders entitled to vote who are present in person or by proxy at a general meeting. A special resolution will be required for important matters such as making changes to our fourth amended and restated memorandum and articles of association.

***Transfer of Ordinary Shares.*** Subject to the restrictions in our fourth amended and restated memorandum and articles of association as set out below, any of our shareholders may transfer all or any of his or her ordinary shares by an instrument of transfer in the usual or common form or any other form approved by our board of directors.

Our board of directors may, in its absolute discretion, decline to register any transfer of any ordinary share which is not fully paid up or on which we have a lien. Our board of directors may also decline to register any transfer of any ordinary share unless:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the instrument of transfer is lodged with us, accompanied by the certificate for the ordinary shares to which it relates and such other evidence as our board of directors may reasonably require to show the right of the transferor to make the transfer;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the instrument of transfer is in respect of only one class of shares;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the instrument of transfer is properly stamped, if required;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•in the case of a transfer to joint holders, the number of joint holders to whom the ordinary share is to be transferred does not exceed four; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•a fee of such maximum sum as the NYSE may determine to be payable or such lesser sum as our directors may from time to time require is paid to us in respect thereof.

If our directors refuse to register a transfer of any share they shall, within two calendar months after the date on which the instrument of transfer was lodged, send to each of the transferor and the transferee notice of such refusal.

The registration of transfers may, after compliance with any notice required of the NYSE, be suspended and the register closed at such times and for such periods as our board of directors may from time to time determine, *provided*, *however*, that the registration of transfers shall not be suspended nor the register closed for more than 30 days in any year.

***Liquidation.*** On a return of capital on winding up or otherwise (other than on conversion, redemption or purchase of ordinary shares), if the assets available for distribution amongst our shareholders shall be more than sufficient to repay the whole of the share capital at the commencement of the winding up, the surplus shall be distributed amongst our shareholders in proportion to the par value of the shares held by them at the commencement of the winding up, subject to a deduction from those shares in respect of which there are monies due, of all monies payable to our company for unpaid calls or otherwise. If our assets available for distribution are insufficient to repay all of the paid-up capital, the assets will be distributed so that the losses are borne by our shareholders in proportion to the par value of the shares held by them. Any distribution of assets or capital to a holder of ordinary share will be the same in any liquidation event.

***Redemption, Repurchase and Surrender of Ordinary Shares.*** We may issue shares on terms that such shares are subject to redemption, at our option or at the option of the holders thereof, on such terms and in such manner as may be determined, before the issue of such shares, by our board of directors. Our company may also repurchase any of our shares provided that the manner and terms of such purchase have been approved by our board of directors or are otherwise authorized by our fourth memorandum and articles of association. Under the Companies Act, the redemption or repurchase of any share may be paid out of our company's profits or out of the proceeds of a fresh issue of shares made for the purpose of such redemption or repurchase, or out of capital (including share premium account and capital redemption reserve) if the company can, immediately following such payment, pay its debts as they fall due in the ordinary course of business. In addition, under the Companies Act no such share may be redeemed or repurchased (a) unless it is fully paid up, (b) if such redemption or repurchase would result in there being no shares outstanding, or (c) if the company has commenced liquidation. In addition, our company may accept the surrender of any fully paid share for no consideration.

***Variations of Rights of Shares.*** If at any time our share capital is divided into different classes or series of shares, the rights attached to any class or series of shares (unless otherwise provided by the terms of issue of the shares of that class or series), whether or not our company is being wound-up, may be varied with the consent in writing of a majority the holders of the issued shares of that class or series or with the sanction of an ordinary resolution at a separate meeting of the holders of the shares of the class or series. The rights conferred upon the holders of the shares of any class issued shall not, unless otherwise expressly provided by the terms of issue of the shares of that class, be deemed to be varied by the creation or issue of further shares ranking *pari passu* with such existing class of shares.

***Inspection of Books and Records.*** Holders of our ordinary shares have no general right under Cayman Islands law to inspect or obtain copies of register of members or our corporate records (other than copies of our memorandum and articles of association, our register of mortgages and charges, and any special resolutions passed by our shareholders). Under Cayman Islands law, the names of current directors can be obtained from a search conducted at the Registrar of Companies in the Cayman Islands. However, we will provide our shareholders with annual audited financial statements. See "—10.H. Document on Display."

***Issuance of Additional Shares.*** Our fourth amended and restated memorandum and articles of association authorizes our board of directors to issue additional ordinary shares from time to time as our board of directors shall determine, to the extent of available authorized but unissued shares.

Our fourth amended and restated memorandum and articles of association also authorizes our board of directors to, without the approval of our shareholders, establish from time to time one or more series of preferred shares and to determine, with respect to any series of preferred shares, the terms and rights of that series, including, among other things:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the designation of the series;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the number of shares of the series;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the dividend rights, conversion rights, and voting rights; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the rights and terms of redemption and liquidation preferences.

Our board of directors may issue preferred shares without action by our shareholders to the extent authorized but unissued. Issuance of these shares may dilute the voting power of holders of ordinary shares.

***Anti-Takeover Provisions.*** Some provisions of our fourth amended and restated memorandum and articles of association may discourage, delay or prevent a change of control of our company or management that shareholders may

------

consider favorable, including provisions that authorize our board of directors to issue authorized preferred shares in one or more series and to designate the price, rights, preferences, privileges and restrictions of such preferred shares without any further vote or action by our shareholders.

***Exempted Company.*** We are an exempted company with limited liability under the Companies Act. The Companies Act distinguishes between ordinary resident companies and exempted companies. Any company that is registered in the Cayman Islands but conducts business mainly outside of the Cayman Islands may apply to be registered as an exempted company. The requirements for an exempted company are essentially the same as for an ordinary company except that an exempted company:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•does not have to file an annual return of its shareholders with the Registrar of Companies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•is not required to open its register of members for inspection;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•does not have to hold an annual general meeting;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•may issue shares with no par value;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•may obtain an undertaking against the imposition of any future taxation (such undertakings are usually given for 30 years in the first instance);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•may register by way of continuation in another jurisdiction and be deregistered in the Cayman Islands;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•may register as a limited duration company; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•may register as a segregated portfolio company.

"Limited liability" means that the liability of each shareholder is limited to the amount unpaid by the shareholder on that shareholder's shares of the company (except in exceptional circumstances, such as involving fraud, the establishment of an agency relationship or an illegal or improper purpose or other circumstances in which a court may be prepared to pierce or lift the corporate veil).

**10. C. Material Contracts**

We have not entered into any material contracts other than in the ordinary course of business and other than those described in this annual report on Form 20-F.

**10. D. Exchange Controls**

See "Item 4. Information on the Company—4.B. Business Overview—Regulation—Regulations Relating to Foreign Exchange."

**10. E. Taxation**

The following discussion of the Cayman Islands, PRC and United States federal income tax consequences of an investment in the ADSs or ordinary shares is based upon laws and relevant interpretations thereof in effect as of the date of this annual report, all of which are subject to change. This discussion does not deal with all possible tax consequences relating to an investment in the ADSs or ordinary shares, such as the tax consequences under state, local and other tax laws. To the extent that the discussion relates to matters of Cayman Islands tax law, it represents the opinion of Maples and Calder (Hong Kong) LLP, our Cayman Islands legal counsel. To the extent that the discussion relates to matters of PRC tax law, it represents the opinion of Tian Yuan Law Firm, our PRC legal counsel.

**Cayman Islands Taxation** 

The Cayman Islands currently levies no taxes on individuals or corporations based upon profits, income, gains or appreciation, and there is no taxation in the nature of inheritance tax or estate duty. There are no other taxes likely to be material to us or holders of the ADSs or ordinary shares levied by the government of the Cayman Islands, except for stamp duties which may be applicable on instruments executed in, or after execution brought within the jurisdiction of the Cayman Islands. The Cayman Islands is not party to any double tax treaties that are applicable to any payments made to or by our company. There are no exchange control regulations or currency restrictions in the Cayman Islands.

Payments of dividends and capital in respect of the ADSs or ordinary shares will not be subject to taxation in the Cayman Islands and no withholding will be required on the payment of a dividend or capital to any holder of the ADSs or ordinary shares, nor will gains derived from the disposal of the ADSs or ordinary shares be subject to Cayman Islands income or corporate tax.

**People's Republic of China Taxation** 

------

Under the PRC EIT Law, which became effective on January 1, 2008 and amended on December 29, 2018, an enterprise established outside the PRC with "de facto management bodies" within the PRC is considered a "resident enterprise" for PRC enterprise income tax purposes and is generally subject to a uniform 25% enterprise income tax rate on its worldwide income. Under the implementation regulations to the PRC EIT Law, a "de facto management body" is defined as a body that has material and overall management and control over the manufacturing and business operations, personnel and human resources, finances and properties of an enterprise.

In addition, the SAT Circular 82 issued by the SAT in April 2009 specifies that certain offshore incorporated enterprises controlled by PRC enterprises or PRC enterprise groups will be classified as PRC resident enterprises if the following are located or resident in the PRC: (a) senior management personnel and departments that are responsible for daily production, operation and management; (b) financial and personnel decision making bodies; (c) key properties, accounting books, company seal, minutes of board meetings and shareholders' meetings; and (d) half or more of the senior management or directors having voting rights. Further to SAT Circular 82, the SAT issued the SAT Bulletin 45, which took effect in September 2011, to provide more guidance on the implementation of SAT Circular 82. SAT Bulletin 45 provides for procedures and administration details of determination on resident status and administration on post-determination matters. Our company is a company incorporated outside the PRC. As a holding company, its key assets are its ownership interests in its subsidiaries, and its key assets are located, and its records (including the resolutions of its board of directors and the resolutions of its shareholders) are maintained, outside the PRC. As such, we do not believe that our company meets all of the conditions above or is a PRC resident enterprise for PRC tax purposes. For the same reasons, we believe our other entities outside of China are not PRC resident enterprises either. 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." There can be no assurance that the PRC government will ultimately take a view that is consistent with us. If the PRC tax authorities determine that our Cayman Islands holding company is a PRC resident enterprise for PRC enterprise income tax purposes, a number of unfavorable PRC tax consequences could follow. For example, a 10% withholding tax would be imposed on dividends we pay to our non-PRC enterprise shareholders (including the ADS holders). In addition, non-resident enterprise shareholders (including the ADS holders) may be subject to PRC tax on gains realized on the sale or other disposition of ADSs or ordinary shares, if such income is treated as sourced from within the PRC. Furthermore, if we are deemed a PRC resident enterprise, dividends paid to our non-PRC individual shareholders (including the ADS holders) and any gain realized on the transfer of 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. See "Item 3. Key Information—3.D. Risk Factors—Risks Related to Doing Business in China—If we are classified as a PRC resident enterprise for PRC enterprise income tax purposes, such classification could result in unfavorable tax consequences to the Group and our non-PRC shareholders and ADS holders."

**Material U.S. Federal Income Tax Considerations** 

The following is a discussion of the material U.S. federal income tax consequences to the U.S. Holders described below of owning and disposing of ADSs or ordinary shares, but it does not purport to be a comprehensive description of all of the tax considerations that may be relevant to a particular person's decision to hold ADSs or ordinary shares. This discussion applies only to a U.S. Holder that holds ADSs or ordinary shares as capital assets for U.S. federal income tax purposes. In addition, it does not describe all of the tax consequences that may be relevant in light of a U.S. Holder's particular circumstances, including alternative minimum tax and Medicare contribution tax consequences, and tax consequences applicable to U.S. Holders subject to special rules, such as:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•certain financial institutions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•dealers or traders in securities that use a mark-to-market method of tax accounting;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•persons holding ADSs or ordinary shares as part of a straddle, wash sale, hedging or conversion transaction or integrated transaction or persons entering into a constructive sale with respect to the ADSs or ordinary shares;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•persons whose functional currency for U.S. federal income tax purposes is not the U.S. dollar;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•entities classified as partnerships for U.S. federal income tax purposes (and investors therein);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•tax-exempt entities, "individual retirement accounts" or "Roth IRAs";

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•persons that own or are deemed to own ADSs or ordinary shares representing ten percent or more of our voting power or value;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•persons who acquired ADSs or ordinary shares pursuant to the exercise of an employee stock option or otherwise as compensation; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•persons holding ADSs or ordinary shares in connection with a trade or business conducted outside of the United States.

------

If an entity that is classified as a partnership for U.S. federal income tax purposes owns ADSs or ordinary shares, the U.S. federal income tax treatment of its partners will generally depend on the status of such partners and the activities of the partnership. Partnerships owning ADSs or ordinary shares and partners in such partnerships should consult their tax advisers as to the particular U.S. federal income tax consequences of owning and disposing of ADSs or ordinary shares.

This discussion is based on the Internal Revenue Code of 1986, as amended, or the Code, administrative pronouncements, judicial decisions and final, temporary and proposed Treasury regulations, and the income tax treaty between the United States and the PRC, or the Treaty, all as of the date hereof, any of which is subject to change, possibly with retroactive effect. This discussion is also based, in part, on representations by the Depositary and assumes that each obligation under the deposit agreement and any related agreement will be performed in accordance with its terms.

For purposes of this discussion, a "U.S. Holder" is a person that is eligible for the benefits of the Treaty, and is a beneficial owner of ADSs or ordinary shares that for U.S. federal income tax purposes is:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•a citizen or individual resident of the United States;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•a corporation, or other entity taxable as a corporation, created or organized in or under the laws of the United States, any state therein or the District of Columbia; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•an estate or trust the income of which is subject to U.S. federal income taxation regardless of its source.

Treasury regulations that apply to taxable years beginning on or after December 28, 2021, or the Foreign Tax Credit Regulations, may in some circumstances prohibit a U.S. person from claiming a foreign tax credit with respect to certain non-U.S. taxes that are not creditable under applicable income tax treaties. The Internal Revenue Service has released notices that provide relief from certain of the provisions of the Foreign Tax Credit Regulations for taxable years ending before the date that a notice or other guidance withdrawing or modifying the temporary relief is issued (or any later date specified in such notice or other guidance). U.S. investors that are not eligible for benefits under the Treaty should consult their tax advisers regarding the creditability or deductibility of any PRC taxes imposed on dividends on, or dispositions of, the ADSs or ordinary shares. This discussion does not apply to investors in this special situation.

U.S. Holders should consult their tax advisers concerning the U.S. federal, state, local and non-U.S. tax consequences of owning and disposing of ADSs or ordinary shares in their particular circumstances.

In general, a U.S. Holder who owns ADSs will be treated as the owner of the underlying shares represented by those ADSs for U.S. federal income tax purposes. Accordingly, no gain or loss will be recognized if a U.S. Holder exchanges ADSs for the underlying shares represented by those ADSs.

***Taxation of Distributions***

The following is subject to the discussion under "—Passive Foreign Investment Company Rules" below.

Distributions paid on the ADSs or ordinary shares, other than certain pro rata distributions of ADSs or ordinary shares, will be treated as dividends to the extent paid out of our current or accumulated earnings and profits (as determined under U.S. federal income tax principles). Because we do not maintain calculations of our earnings and profits under U.S. federal income tax principles, it is expected that distributions generally will be reported to U.S. Holders as "dividends" for U.S. federal income tax purposes. Such dividends will not be eligible for the dividends-received deduction generally available to U.S. corporations under the Code. Subject to applicable limitations, dividends paid to certain non-corporate U.S. Holders may be taxable at reduced rates. Non-corporate U.S. Holders should consult their tax advisers regarding the availability of the reduced tax rate on dividends in their particular circumstances.

Dividends will be included in a U.S. Holder's income generally on the date of the U.S. Holder's, or in the case of ADSs, the Depositary's, receipt. The amount of any dividend income paid in currency other than U.S. dollars will be the U.S. dollars amount calculated by reference to the spot rate in effect on the date of receipt, regardless of whether the payment is in fact converted into U.S. dollars on such date. If the dividend is converted into U.S. dollars on the date of receipt, a U.S. Holder generally should not be required to recognize foreign currency gain or loss in respect of the amount received. A U.S. Holder may have foreign currency gain or loss if the dividend is converted into U.S. dollars after the date of receipt.

Dividends will be treated as foreign-source income for foreign tax credit purposes. As described in "—People's Republic of China Taxation," dividends paid by us may be subject to PRC withholding tax. For U.S. federal income tax purposes, the amount of the dividend income will include amounts withheld in respect of the PRC withholding tax. Subject to applicable limitations, which vary depending upon the U.S. Holder's circumstances, PRC taxes withheld from dividend payments (at a rate not exceeding the applicable rate provided in the Treaty) generally will be creditable against a U.S. Holder's U.S. federal income tax liability. In lieu of claiming a credit, a U.S. Holder may elect to deduct such PRC taxes in computing its taxable income, subject to applicable limitations. An election to deduct creditable foreign taxes instead of claiming foreign tax credits must apply to all creditable foreign taxes paid or accrued in the taxable year. The rules governing deductions and credits for foreign taxes are complex, and U.S. Holders should consult their tax advisers regarding the creditability or deductibility of foreign taxes in their particular circumstances.

------

***Sale or Other Disposition of ADSs or Ordinary Shares***

The following is subject to the discussion under "—Passive Foreign Investment Company Rules" below.

For U.S. federal income tax purposes, gain or loss realized on the sale or other taxable disposition of ADSs or ordinary shares will be capital gain or loss, and will be long-term capital gain or loss if the U.S. Holder held the ADSs or ordinary shares for more than one year. The amount of the gain or loss will equal the difference between the U.S. Holder's tax basis in the ADSs or ordinary shares disposed of and the amount realized on the disposition, in each case as determined in U.S. dollars.

As described in "—People's Republic of China Taxation" above, gains on the sale of ADSs or ordinary shares may be subject to PRC taxes if we are treated as a PRC resident enterprise for PRC tax purposes. Under the Code, capital gains of U.S. persons are generally treated as U.S.-source income. However, a U.S. Holder may be able to elect to treat the gain as foreign-source income under the Treaty and claim foreign tax credit in respect to any PRC tax on dispositions. The Foreign Tax Credit Regulations generally preclude a U.S. Holder from claiming a foreign tax credit with respect to PRC income taxes on gains from dispositions of ADSs or ordinary shares if the U.S. Holder does not elect to apply the benefits of the Treaty. However, in that case it is possible that any PRC taxes on disposition gains may either be deductible or reduce the amount realized on the disposition. The rules governing foreign tax credits and deductibility of foreign taxes are complex. U.S. Holders should consult their tax advisers regarding the consequences of the imposition of any PRC tax on disposition gains, including the Treaty's resourcing rule, any reporting requirements with respect to a Treaty-based return position and the creditability or deductibility of the PRC tax in their particular circumstances (including any applicable limitations).

***Passive Foreign Investment Company Rules***

In general, a non-U.S. corporation is a PFIC for any taxable year in which (i) 75% or more of its gross income consists of passive income or (ii) 50% or more of the average quarterly value of its assets consists of assets that produce, or are held for the production of, passive income. For purposes of the above calculations, a non-U.S. corporation that owns, directly or indirectly, at least 25% by value of the shares of another corporation is treated as if it held its proportionate share of the assets of the other corporation and received directly its proportionate share of the income of the other corporation. Passive income generally includes dividends, interest, rents, royalties and certain gains. Passive income generally includes dividends, interest, rents, royalties and investment gains. Cash is a passive asset for these purposes. Goodwill and other intangible assets are active assets under the PFIC rules to the extent attributable to activities that produce active income.

The determination of our PFIC status is subject to certain uncertainties and is made by applying principles and methodologies that are in some circumstances unclear.

Based on the composition of our income and assets and the value of our assets, including goodwill and other intangible assets, which is based on the market price of the ADSs, we believe that we were likely a PFIC for the 2025 taxable year. In addition, it is not entirely clear how the contractual arrangements between our wholly-owned PRC subsidiaries, our consolidated affiliated entities and the shareholders of our consolidated affiliated entities will be treated for purposes of the PFIC rules. Because the treatment of the contractual arrangements is not entirely clear, because we hold a substantial amount of cash, and because PFIC status depends upon 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 has been, and may continue to be, volatile), there is a risk that we may be a PFIC for our current taxable year and possibly future taxable years.

If we are or were a PFIC for any taxable year and any of our subsidiaries, consolidated affiliated entities or other companies in which we own or are treated as owning equity interests were also a PFIC (any such entity, a "Lower-tier PFIC"), U.S. Holders would be deemed to own a proportionate amount (by value) of the shares of each Lower-tier PFIC and would be subject to U.S. federal income tax according to the rules described in the subsequent paragraph on (i) certain distributions by a Lower-tier PFIC and (ii) dispositions of shares of Lower-tier PFICs, in each case as if the U.S. Holders held such shares directly, even though the U.S. Holders had not received the proceeds of those distributions or dispositions.

In general, if we are or were a PFIC for any taxable year during which a U.S. Holder holds ADSs or ordinary shares, gain recognized by such U.S. Holder on a sale or other disposition (including certain pledges) of its ADSs or ordinary shares would be allocated ratably over that U.S. Holder's holding period. The amounts allocated to the taxable year of the sale or disposition and to any year before we became a PFIC would be taxed as ordinary income. The amount allocated to each other taxable year would be subject to tax at the highest rate in effect for individuals or corporations, as appropriate, for that taxable year, and an interest charge would be imposed on the resulting tax liability for each such year. Furthermore, to the extent that distributions received by a U.S. Holder in any year on its ADSs or ordinary shares exceed 125% of the average of the annual distributions on the ADSs or ordinary shares received during the preceding three taxable years or the U.S. Holder's holding period for the ADSs or ordinary shares, whichever is shorter, such distributions would be subject to taxation in the same manner.

Alternatively, if we are or were a PFIC and if the ADSs were "regularly traded" on a "qualified exchange," as defined in applicable Treasury regulations, a U.S. Holder could make a mark-to-market election that would result in tax treatment different from the general tax treatment for PFICs described in the preceding paragraph. The ADSs would be treated as

------

"regularly traded" for any calendar year in which more than a de minimis quantity of the ADSs were traded on a qualified exchange on at least 15 days during each calendar quarter. The New York Stock Exchange, where the ADSs are listed, is a qualified exchange for this purpose. U.S. Holders will not be able to make a mark-to-market election with respect to Lower-tier PFICs, if any. Accordingly, if we were a PFIC for any taxable year, a U.S. Holder that makes the mark-to-market election may continue to be subject to the general PFIC rules with respect to such U.S. Holder's indirect interest in any Lower-tier PFICs.

If a U.S. Holder makes the mark-to-market election, the U.S. Holder generally will recognize as ordinary income any excess of the fair market value of the ADSs at the end of each taxable year over their adjusted tax basis, and will recognize an ordinary loss in respect of any excess of the adjusted tax basis of the ADSs over their fair market value at the end of the taxable year (but only to the extent of the net amount of income previously included as a result of the mark-to-market election). If a U.S. Holder makes the election, the U.S. Holder's tax basis in the ADSs will be adjusted to reflect the income or loss amounts recognized. Any gain recognized on the sale or other disposition of ADSs in a year when we are a PFIC will be treated as ordinary income and any loss will be treated as an ordinary loss (but only to the extent of the net amount of income previously included as a result of the mark-to-market election, with any excess treated as capital loss).

If a U.S. Holder makes the mark-to-market election, distributions paid on ADSs will be treated as discussed under "—Taxation of Distributions" above. However, regardless of whether a U.S. Holder makes the mark-to-market election, if we were a PFIC or, with respect to particular U.S. Holder, were treated as a PFIC for the taxable year in which we paid a dividend or for the prior taxable year, the preferential dividend rates discussed above with respect to dividends paid to certain non-corporate U.S. Holders would not apply.

If we are or were a PFIC for any taxable year during a U.S. Holder's holding period for ADSs or ordinary shares, we will generally continue to be treated as a PFIC with respect to the U.S. Holder for all succeeding years during which the U.S. Holder owns ADSs or ordinary shares, even if we cease to meet the threshold requirements for PFIC status. If we are or were a PFIC for any taxable year but cease to be a PFIC for subsequent years, U.S. Holders should consult their tax advisers regarding the advisability of making a "deemed sale" election that would allow them to eliminate the continuing PFIC status under certain circumstances but may require them to recognize gain taxed under the general PFIC rules described above.

We do not intend to provide the information that would otherwise enable U.S. Holders to make a "qualified electing fund election," which would have resulted in alternate treatment if we are or were a PFIC for any taxable year.

If we are or were a PFIC for any taxable year during which a U.S. Holder owned any ADSs or ordinary shares, the U.S. Holder would generally be required to file annual reports with the Internal Revenue Service.

U.S. Holders should consult their tax advisers regarding the determination of whether we are or were a PFIC for any taxable year and the potential application of the PFIC rules to their ownership of ADSs or ordinary shares.

***Information Reporting and Backup Withholding***

Payments of dividends and sales proceeds from the sale or exchange of the ADSs or ordinary shares, that are made within the United States or through certain U.S.-related financial intermediaries generally are subject to information reporting, and may be subject to backup withholding, unless (i) the U.S. Holder is a corporation or other exempt recipient or (ii) in the case of backup withholding, the U.S. Holder provides a correct taxpayer identification number and certifies that it is not subject to backup withholding, generally on Internal Revenue Service Form W-9. Backup withholding is not an additional tax. The amount of any backup withholding from a payment to a U.S. Holder will be allowed as a credit against the holder's U.S. federal income tax liability and may entitle it to a refund, provided that the required information is timely furnished to the Internal Revenue Service.

Certain U.S. Holders who are individuals (or entities formed or availed of to hold certain "specified foreign financial assets") may be required to report information relating to their ownership of ADSs or ordinary shares, unless the ADSs or ordinary shares are held in accounts at financial institutions (in which case the accounts may be reportable if maintained by non-U.S. financial institutions). U.S. Holders should consult their tax advisers regarding their reporting obligations with respect to the ADSs or ordinary shares.

Exchange Act, we are required to file reports and other information with the SEC. Specifically, we are required to file annually a Form 20-F no later than four months after the close of each fiscal year. Copies of reports and other information, when so filed, may be inspected without charge and may be obtained at prescribed rates at the public reference facilities maintained by the SEC at 100 F Street, N.E., Room 1580, Washington, D.C. 20549. The public may obtain information regarding the Washington, D.C. Public Reference Room by calling the SEC at 1-800-SEC-0330. The SEC also maintains a web site at www.sec.gov that contains reports, proxy and information statements, and other information regarding registrants that make electronic filings with the SEC using its EDGAR system. As a foreign private issuer, we are exempt from the rules under the Exchange Act prescribing the furnishing and content of quarterly reports and proxy statements, and officers, directors and principal shareholders are exempt from the reporting and short-swing profit recovery provisions contained in Section 16 of the Exchange Act.

We will furnish The Bank of New York Mellon, the depositary of the ADSs, with our annual reports, which will include a review of operations and annual audited consolidated financial statements prepared in conformity with U.S. GAAP, and all notices of shareholders' meetings and other reports and communications that are made generally available to our shareholders. The depositary will make such notices, reports and communications available to holders of ADSs and, upon our request, will mail to all record holders of ADSs the information contained in any notice of a shareholders' meeting received by the depositary from us.

**ITEM 11. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK**

***Interest Rate Risk***

The Group's exposure to interest rate risk primarily relates to the interest income generated by excess cash, which is mostly held in interest-bearing bank deposits. The Group has not used any derivative financial instruments to manage the Group's interest risk exposure. Interest-earning instruments carry a degree of interest rate risk. The Group has not been exposed, nor does the Group anticipate being exposed, to material risks due to changes in interest rates. However, the Group's future interest income may be lower than expected due to changes in market interest rates.

The Group may also be subject to interest rate risk in relation to the installment payment option that the Group offers to students that enables them to finance all or part of their tuition from loans provided by third-party credit providers. The borrowing student is obligated to repay the loan principal in installments over a period ranging from 3 to 12 months, while the Group is generally obligated to pay the full amount of interest payable to the credit providers at the very beginning of the loan. The Group may be subject to risks associated with an increase in interest rates to the extent that the Group continues to agree to make the interest payments under such loans. In 2023, 2024 and 2025, the Group's student loan coverage ratio was 1.3%, 1.9% and 1.7%, respectively. For the same periods, the Group made interest payments of RMB1.5 million, RMB1.7 million and RMB1.9 million (US$0.3 million), respectively, to the credit providers.

***Foreign Exchange Risk***

Substantially all of the Group's revenues are denominated in Renminbi. Renminbi is not freely convertible into foreign currencies for capital account transactions. The value of Renminbi against U.S. dollars and other currencies is affected by, among other things, changes in China's political and economic conditions and China's foreign exchange policies. On July 21, 2005, the PRC government changed its decade-old policy of pegging the value of Renminbi to U.S. dollars, and Renminbi appreciated more than 20% against U.S. dollars over the following three years. Since June 2010, Renminbi has fluctuated against U.S. dollars, at times significantly and unpredictably. It is difficult to predict how market forces or PRC or U.S. government policy may impact the exchange rate between Renminbi and U.S. dollars in the future.

To date, the Group has not entered into any hedging transactions in an effort to reduce the exposure to foreign currency exchange risk.

***Inflation Risk***

Since the Group's inception, inflation in China has not materially impacted the Group's results of operations. According to the National Bureau of Statistics of China, the year-over-year percent changes in the consumer price index were decreases of 0.3% for December 2023, increase of 0.1% for December 2024, and increases of 0.8% for December 2025, respectively. Although the Group has not in the past been materially affected by inflation since the Group's inception, the Group can provide no assurance that the Group will not be affected in the future by higher rates of inflation in China.

---

The depositary collects its fees for delivery and surrender of ADSs directly from investors depositing shares or surrendering ADSs for the purpose of withdrawal or from intermediaries acting for them. The depositary collects fees for making distributions to investors by deducting those fees from the amounts distributed or by selling a portion of distributable property to pay the fees. The depositary may collect its annual fee for depositary services by deduction from cash distributions or by directly billing investors or by charging the book-entry system accounts of participants acting for them. The depositary may collect any of its fees by deduction from any cash distribution payable (or by selling a portion of securities or other property distributable) to ADS holders that are obligated to pay those fees. The depositary may generally refuse to provide fee-attracting services until its fees for those services are paid.

From time to time, the depositary may make payments to us to reimburse us for costs and expenses generally arising out of establishment and maintenance of the ADS program, waive fees and expenses for services provided to us by the depositary or share revenue from the fees collected from ADS holders. In performing its duties under the deposit agreement, the depositary may use brokers, dealers, foreign currency dealers or other service providers that are owned by or affiliated with the depositary and that may earn or share fees, spreads or commissions. In 2025, we did not receive any net reimbursement from the Bank of New York Mellon for the expenses incurred in connection with our ADS program.

The depositary may convert currency itself or through any of its affiliates and, in those cases, acts as principal for its own account and not as agent, advisor, broker or fiduciary on behalf of any other person and earns revenue, including, without limitation, transaction spreads, that it will retain for its own account. The revenue is based on, among other things, the difference between the exchange rate assigned to the currency conversion made under the deposit agreement and the rate that the depositary or its affiliate receives when buying or selling foreign currency for its own account. The depositary

------

makes no representation that the exchange rate used or obtained in any currency conversion under the deposit agreement will be the most favorable rate that could be obtained at the time or that the method by which that rate will be determined will be the most favorable to ADS holders, subject to the depositary's obligations under the deposit agreement. The methodology used to determine exchange rates used in currency conversions is available upon request.

**14. A. – 14.D. Material Modifications to the Rights of Security Holders**

See "Item 10. Additional Information" for a description of the rights of shareholders, which remain unchanged.

**14. E. Use of Proceeds**

The following "Use of Proceeds" information relates to the registration statement on Form F-1, as amended (File No. 333-223190) (the "F-1 Registration Statement") in relation to our initial public offering of 13,000,000 ADSs representing 520,000 Class A ordinary shares, at an initial offering price of US$11.50 per ADS. Our initial public offering closed in March 2018. Goldman Sachs (Asia) L.L.C., J.P. Morgan Securities LLC and Credit Suisse Securities (USA) LLC were the representatives of the underwriters.

The F-1 Registration Statement was declared effective by the SEC on March 22, 2018. The total expenses incurred for our company's account in connection with our initial public offering was approximately US$12.8 million, which included US$10.5 million in underwriting discounts and commissions for the initial public offering and approximately US$2.3 million in other costs and expenses for our initial public offering. We received net proceeds of approximately US$176.8 million from our initial public offering and the concurrent private placements in connection with the initial public offering to DIAMOND TOWER INVESTMENTS LIMITED and ELITE CONCEPT HOLDINGS LIMITED. None of the transaction expenses included payments to directors or officers of our company or their associates, persons owning more than 10% or more of our equity securities or our affiliates. None of the net proceeds we received from the initial public offering were paid, directly or indirectly, to any of our directors or officers or their associates, persons owning 10% or more of our equity securities or our affiliates.

As of December 31, 2025, we had used a portion of the net proceeds received from our initial public offering and the concurrent private placement, which consisted of US$18.1 million for repurchase program, US$200.2 million for capital injection to our wholly-owned subsidiaries in China, and US$9.5 million for special cash dividend.

**ITEM 15. CONTROLS AND PROCEDURES**

**Disclosure Controls and Procedures**

Our management, with the participation of our Chief Executive Officer and Financial Controller, has performed an evaluation of the effectiveness of the Group's disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act) as of the end of the period covered by this report, as required by Rule 13a-15(b) under the Exchange Act.

Based upon that evaluation, our management has concluded that, as of December 31, 2025, the Group's disclosure controls and procedures were effective in ensuring that the information required to be disclosed by us in the reports that we file or submit under the Exchange Act was recorded, processed, summarized and reported, within the time periods specified in the SEC's rules and forms, and that the information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including our Chief Executive Officer and Financial Controller, to allow timely decisions regarding required disclosure.

**Management's Annual Report on Internal Control over Financial Reporting** 

Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. As required by Rule 13a-15(c) of the Exchange Act, our management conducted an evaluation of the Group's internal control over financial reporting as of December 31, 2025 based on the framework in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, our management concluded that the Group's internal control over financial reporting was effective as of December 31, 2025.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness of the Group's internal control over financial reporting to future periods are subject to the risks that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

**Attestation Report of the Registered Public Accounting Firm**

Because we are a non-accelerated filer, this annual report on Form 20-F does not include an attestation report of our registered public accounting firm regarding internal control over financial reporting.

**Changes in Internal Control over Financial Reporting**

There were no changes in the Group's internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the period covered by this annual report on Form 20-F that have materially affected, or that are reasonably likely to materially affect, the Group's internal control over financial reporting.

**ITEM 16. G. Corporate Governance**

As a Cayman Islands exempted 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 currently 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 continue 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. See "Item 3. Key Information—3.D. Risk Factors—Risks Relating to the ADSs—As an exempted 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. These practices may afford less protection to shareholders than they wouldenjoy if we complied fully with the New York Stock Exchange corporate governance listing standards."

**ITEM 16. K. CYBERSECURITY**

At Sunlands, cybersecurity risk management is an integral part of our overall risk management program. Our cybersecurity risk management program is designed to align with industry best practices and provide a framework for handling cybersecurity threats and incidents, including threats and incidents associated with the use of services provided by third-party service providers, and facilitate coordination across different departments of our company. This framework includes steps for assessing the severity of a cybersecurity threat, identifying the source of a cybersecurity threat including whether the cybersecurity threat is associated with a third-party service provider, implementing cybersecurity countermeasures and mitigation strategies and informing management and our board of directors of material cybersecurity threats and incidents. Our cybersecurity team is responsible for assessing our cybersecurity risk management program and we currently do not engage third parties for such assessment. In addition, our cybersecurity team provides training to all key employees for product development regularly.

Our board of directors has overall oversight responsibility for our risk management, and delegates cybersecurity risk management oversight to the audit committee of the board of directors. The audit committee is responsible for ensuring that management has processes in place designed to identify and evaluate cybersecurity risks to which the company is exposed and implement processes and programs to manage cybersecurity risks and mitigate cybersecurity incidents. The audit committee also reports material cybersecurity risks to our full board of directors. Management is responsible for identifying, considering and assessing material cybersecurity risks on an ongoing basis, establishing processes to ensure that such potential cybersecurity risk exposures are monitored, putting in place appropriate mitigation measures and maintaining cybersecurity programs. Our cybersecurity programs are under the direction of our chief executive officer who receives reports from our cybersecurity team and monitors the prevention, detection, mitigation, and remediation of cybersecurity incidents. Our chief executive officer has rich management experience, including cybersecurity management. Our vice president of product development, the leader of our cybersecurity team, as well as dedicated personnel, are experienced information system security professionals and information security managers with years of experience. Management, including the chief executive officer and our cybersecurity team, regularly update the audit committee on the company's cybersecurity programs, material cybersecurity risks and mitigation strategies and provide cybersecurity reports annually that cover, among other topics, developments in cybersecurity and updates to the company's cybersecurity programs and mitigation strategies.

In 2025, we did not identify any cybersecurity threats that have materially affected or are reasonably likely to materially affect the Group's business strategy, results of operations, or financial condition. However, despite our efforts, we cannot eliminate all risks from cybersecurity threats, or provide assurances that we have not experienced an undetected cybersecurity incident. For more information about these risks, please see "Item 3. Key Information—3.D. Risk Factors—Risks Related to the Group's Business—Privacy concerns could limit the Group's ability to collect and leverage the Group's user data and disclosure of user data could adversely impact the Group's business and reputation."

**REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM**

To the Board of Directors and Shareholders of Sunlands Technology Group

**Opinion on the Financial Statements**

We have audited the accompanying consolidated balance sheets of Sunlands Technology Group and its subsidiaries (the "Company") as of December 31, 2024 and 2025, the related consolidated statements of operations, comprehensive income, changes in shareholders' (deficit)/equity and cash flows for each of the three years in the period ended December 31, 2025, and the related notes and Schedule I (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2025, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025, in conformity with accounting principles generally accepted in the United States of America.

**Convenience Translation**

Our audits also comprehended the translation of Renminbi amounts into United States dollar amounts and, in our opinion, such translation has been made in conformity with the basis stated in Note 2 to the financial statements. Such United States dollar amounts are presented solely for the convenience of readers outside the People's Republic of China.

**Basis for Opinion**

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

**Critical Audit Matter**

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matter does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

**Critical Audit Matter-continued**

***Revenue recognition - Online education services - Refer to Note 2 to the financial statements***

*Critical Audit Matter Description*

The revenues of the Company are primarily derived from service fees that the Company charges participants in advance for its online education services, which accounted for 87.9% of the total net revenues for the year ended December 31, 2025. The Company recognizes the revenues for online education services on a straight-line basis over the service period.

We identified the revenue recognition of online education services as a critical audit matter due to the inherent risk associated with the occurrence of revenue given the significant volume of individually-low-monetary-value revenue transactions generated from online education services. This required an increased extent of effort to determine the nature, timing and extent of audit evidence required to be obtained.

*How the Critical Audit Matter Was Addressed in the Audit*

Our audit procedures related to address this critical audit matter included the following, among others:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•With the assistance of our IT professionals and data analytics specialists, we:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Identified the relevant systems used to process revenue transactions and tested the general IT controls over each of these systems, including testing of user access controls, change management controls, and IT operations controls.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Performed testing of automated controls over revenue recognition with respect to the online education services.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Performed procedures to reconcile the cash received and recorded in the payment system with the collection statements from major third-party online payment channels and bank statements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•For a sample of revenue transaction, recalculated the revenue amount of online education services recognized by utilizing computer-assisted audit techniques.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Performed data analytics on participants' online learning records and evaluated trends in the gross billings.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•We tested relevant manual controls related to the online education services process.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•For a sample of revenue transaction, we performed detail transaction testing by agreeing the amounts recognized to supporting documents including but not limited to the online education services contracts and cash collections.

**2.** **SIGNIFICANT ACCOUNTING POLICIES**

***Basis of presentation and use of estimates***

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP").

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the balance sheet dates and the reported amounts of revenues and expenses during the reporting periods. Significant estimates and assumptions reflected in the Group's financial statements include, but are not limited to, revenue recognition and refund liabilities. Actual results could materially differ from those estimates.

***Principles of consolidation***

The consolidated financial statements include the financial statements of the Company and its subsidiaries, and VIEs and VIEs' subsidiaries. All intercompany transactions and balances are eliminated upon consolidation.

***The VIE arrangements***

There are uncertainties as to whether applicable PRC laws and regulations prohibit foreign investors from providing telecommunications value-added services in the PRC. As a Cayman Islands corporation, the Company is deemed a foreign legal person under PRC laws. Accordingly, the Company's wholly owned subsidiaries in the PRC, as foreign invested companies, may be deemed to be telecommunications value-added services providers in the PRC. To comply with these foreign ownership restrictions, the Company operates its online education services partially through the VIEs and their subsidiaries, in the PRC. The Company through its wholly owned subsidiaries ("WFOEs") located in the PRC entered into a series of contractual agreements with the VIEs and their shareholders. Through below contractual agreements, the Company has (1) the power to direct the activities that most significantly affect the economic performance of the VIEs, and (2) the right to receive the economic benefit of the VIEs that could potentially be significant to the VIEs. As a result, the shareholders of the VIEs lack the power to direct the activities of the VIEs that most significantly impact the entity's economic performance, the obligation to absorb the expected losses, and the right to receive the expected residual returns of the entity. Accordingly, the Company is considered as the primary beneficiary of the VIEs, and the Company has consolidated the financial results of the VIEs and their subsidiaries in its consolidated financial statements.

In December 2025, Beijing Sunlands terminated its VIE Contractual Arrangements with Wuhan Zhibo. The shareholders of Beijing Sunlands transferred all of their shares in Beijing Sunlands to Wuhan Zhibo, resulting in Beijing Sunlands becoming a wholly owned subsidiary of Wuhan Zhibo in the same day.

As of December 31, 2025, the Group's VIE that was material to the Group's business and operations was Beijing Lingding.

*Exclusive Technical Consultation and Service Agreement*

Under the exclusive technical consultation and service agreement among WFOEs, and VIEs and the subsidiaries of VIEs, WFOEs have the exclusive right to provide, among other things, technical consultation and services to VIEs and VIEs' subsidiaries, and VIEs and VIEs' subsidiaries agree to accept all the consultation and services provided by WFOEs. Without WFOEs' prior written consent, VIEs and VIEs' subsidiaries are prohibited from engaging any third party to provide any services contemplated by this agreement. In addition, WFOEs have exclusive and proprietary ownership, rights and interests in any and all intellectual properties arising out of or created during the performance of this agreement. VIEs and VIEs' subsidiaries agree to pay a quarterly service fee to WFOEs at an aggregate amount of a certain percentage ranging from 10% to 100% of VIEs and VIEs' subsidiaries' monthly revenue. Unless terminated by WFOEs, this agreement will remain effective until the dissolution of VIEs and VIEs' subsidiaries. Without WFOEs' prior written consent, VIEs and VIEs' subsidiaries do not have the right to terminate this exclusive technical consultation and service agreement.

VIEs, VIEs' subsidiaries and the shareholders of VIEs shall accept and execute opinions and instructions of WFOEs in connection with the employee engagement and dismissal, daily operations and financial management systems. The shareholders of VIEs shall elect or appoint the candidates recommended by WFOEs as VIEs' directors and supervisors, and procure the appointment of VIEs' chairman of the board and senior management pursuant to WFOEs' designation. The agreement also provides that if any of the agreements among WFOEs, VIEs and the VIEs' subsidiaries is terminated, WFOEs are entitled to terminate all of the other agreements among themselves, VIEs and VIEs' subsidiaries. This agreement will remain binding until dissolution of VIEs and all the VIEs' subsidiaries.

*Equity Interest Pledge Agreement*

Pursuant to the equity interest pledge agreement among WFOEs, the shareholders of VIEs and the subsidiaries of VIEs, the shareholders of VIEs pledged all of their equity interests in VIEs to WFOEs as security for performance of the obligations of VIEs and their shareholders under the exclusive technical consultation and service agreements, the option agreement and the business operation agreement. The shareholders of VIEs shall instruct VIEs not to distribute any dividends and shall not approve any profit distribution plan. If any of the specified events of default occurs, WFOEs may exercise the right to enforce the pledges after giving a notice of default to the shareholders of VIEs. WFOEs may assign any and all of its rights and obligations under equity interest pledge agreement to their designee(s) at any time. The equity interest pledge agreement is binding on the shareholders of VIEs and their successors and shall be valid with respect to the shareholders of VIEs and each of their successors.

*Option Agreement* 

Pursuant to the option agreement among WFOEs, VIEs and the shareholders of VIEs, each of the shareholders irrevocably granted WFOEs a right to purchase or designate a third party to purchase, equity interests in VIEs then held by each shareholder at once or at multiple times at any time in part or in whole at WFOEs' sole and absolute discretion to the extent permitted by PRC laws. The shareholders of VIEs shall promptly surrender all considerations they received from the exercise of the options to WFOEs or the designated third party free of charge. Without WFOEs' prior written consent, the shareholders of VIEs shall not, individually or collectively, make or procure VIEs to make any transaction or conduct that has a material adverse effect on the assets, liabilities, operations, equity and other legal rights of VIEs. Without WFOEs' prior written consent, VIEs shall not enter into any contract exceeding RMB50, except the contracts in the ordinary course of the business. VIEs shall not be dissolved or liquidated without prior written consent by WFOEs. The shareholders of VIEs waive their rights of pre-emption in regard to the transfer of equity interest by any other shareholder of VIEs to WFOEs as instructed.

***The VIE arrangements*** – continued

*Powers of Attorney*

Pursuant to the powers of attorney executed by the shareholders of VIEs, the shareholders of VIEs each irrevocably authorized WFOEs to act on their respective behalf as exclusive agent and attorney with respect to all rights of shareholders concerning all equity interests held by each of them in VIEs, including but not limited to propose to convene shareholder meetings, accept any notice with respect to the convening and proceeding of the shareholder meeting, attend shareholder meetings, sign the shareholders resolutions on behalf of, exercise all the shareholder's rights according to laws and regulations and VIEs' articles of association (including but not limited to voting rights and the sale, transfer, pledge, or dispose of all equity interests held in part or in whole), and designate and appoint on their respective behalf the president, directors, supervisors, Chief Executive Officer, Chief Financial Officer and other senior management members of VIEs.

*Spousal Consent Letters*

Pursuant to the spousal consent letters executed by the spouses of the general partners of entities as the shareholders of VIEs, the signing spouse confirmed and agreed that the equity interests of VIEs are the own property of their spouses and shall not constitute the jointly possessed property of the couples. The spouses also irrevocably waived any potential right or interest that may be granted by operation of applicable law in connection with the equity interests of VIEs held by their spouses.

As a result of the contractual arrangements above, WFOEs bear the economic risks and receive the economic benefits of the VIEs and are the primary beneficiary of the VIEs. Therefore, the Company has consolidated the financial results of the VIEs and their subsidiaries in its consolidated financial statements.

<u>Risks in relation to VIE structure</u>

The Company believes that the contractual arrangements with VIEs and their shareholders are in compliance with existing PRC laws and regulations and are legally enforceable. However, the contractual arrangements are subject to risks and uncertainties, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•VIEs and their shareholders may have or develop interests that conflict with the Group's interests, which may lead them to pursue opportunities in violation of the aforementioned contractual agreements. If the Group cannot resolve any conflicts of interest or disputes between the Group and the shareholders of VIEs, the Group would have to rely on legal proceedings, which could result in disruption of its business, and there is uncertainty as to the outcome of any such legal proceedings.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•VIEs and their shareholders could fail to obtain the proper operating licenses or fail to comply with other regulatory requirements. As a result, the PRC government could impose fines, new requirements or other penalties on the VIEs or the Group, mandate a change in ownership structure or operations for the VIEs or the Group, restrict the VIEs or the Group's use of financing sources or otherwise restrict the VIEs or the Group's ability to conduct business.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•The PRC government may declare the aforementioned contractual arrangements invalid. They may modify the relevant regulations, have a different interpretation of such regulations, or otherwise determine that the Group or the VIEs have failed to comply with the legal obligations required to effectuate such contractual arrangements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•If the legal structure and contractual arrangements were found to be in violation of PRC laws and regulations, the PRC government may restrict or prohibit the Group's business and operations in China.

The Group's ability to conduct its business may be negatively affected if the PRC government were to carry out any of the aforementioned actions. As a result, the Group may not be able to consolidate VIEs and their subsidiaries in the consolidated financial statements as the Group may lose the ability to direct the activities that most significantly affect the economic performance of the VIEs and the Group may lose the ability to receive economic benefits from VIEs.

There are no consolidated VIEs' assets that are collateral for the VIEs' obligations and which can only be used to settle the VIEs' obligations. No creditor (or beneficial interest holders) of the VIEs have recourse to the general credit of the Company or any of its consolidated subsidiaries. No terms in any arrangements, considering both explicit arrangements and implicit variable interests, require the Company or its subsidiaries to provide financial support to the VIEs. However, if the VIEs ever needs financial support, the Company or its subsidiaries may, at its option and subject to statutory limits and restrictions, provide financial support to the VIEs through loans to the shareholders of the VIEs or entrustment loans to the VIEs.

***Foreign currency translation and transactions***

The Group's reporting currency is the Renminbi ("RMB"). The functional currency of the subsidiaries incorporated outside the mainland China is the United States dollar ("US dollar" or "US$"). The functional currency of all the other subsidiaries, the VIEs and VIEs' subsidiaries is the RMB.

Monetary assets and liabilities denominated in currencies other than the applicable functional currencies are translated into the functional currencies at the prevailing rates of exchange at the balance sheet date. Nonmonetary assets and liabilities are remeasured into the applicable functional currencies at historical exchange rates. Revenues and expenses are translated using the average rate of exchange in effect during the reporting period. Translation adjustments are reported and shown as a separate component of other comprehensive income/(loss)

***Foreign currency translation and transactions*** – continued

Transactions in currencies other than the functional currencies during the year are converted into the applicable functional currencies at the applicable rates of exchange prevailing at the dates of the transactions. Transaction gains and losses are recorded in the consolidated statements of operations.

***Convenience Translation***

The Group's business is primarily conducted in China and all of the revenues are denominated in RMB. However, periodic reports made to shareholders will include current period amounts translated into US dollars using the exchange rate as of balance sheet date, for the convenience of the readers. Translations of balances in the consolidated balance sheets, and the related consolidated statements of operations, shareholders' deficit and cash flows from RMB into US dollars as of and for the year ended December 31, 2025 are solely for the convenience of the readers and were calculated at the rate of US$1.00 = RMB6.9931, representing the noon buying rate set forth in the H.10 statistical release of the U.S. Federal Reserve Board on December 31, 2025. No representation is made that the RMB amounts could have been, or could be, converted, realized or settled into US$ at that rate on December 31, 2025, or at any other rate.

***Cash and cash equivalents***

Cash and cash equivalents comprise cash at banks and on hand and term deposits, which have original maturities of three months or less when purchased and are subject to an insignificant risk of changes in value. The carrying value of cash equivalents approximates market value.

***Restricted cash***

Cash that is restricted as to withdrawal or for use or pledged as security is separately reported. The Group's restricted cash mainly represents security deposits for an investment account.

***Short-term investments***

*Variable rate financial instruments*

The Group holds investment products with variable interest rates, which are unsecured principal and no restriction on withdrawal. The Group elects the fair value option to record them at fair value in accordance with Accounting Standards Codification ("ASC") 825 Financial Instruments. Changes in the fair value are recorded in the consolidated statements of operations.

*Held-to-maturity investments*

The Group holds deposits in banks that earn fixed interest rate return only if the Group holds them to maturity. The original maturities of deposits reported as short-term investments are greater than three months, but less than twelve months. As the Group has the positive intent and ability to hold the deposits to maturity, they are classified as held-to-maturity and recorded at amortized cost.

***Long-term investments***

*Available-for-sale investments*

The Group holds long-term notes issued by financial institutions and classifies them as available-for-sale investments if they do not meet the criteria of either trading or held-to-maturity investments. Available-for-sale investments are reported at fair value, with unrealized gains and losses recorded in accumulated other comprehensive income as a component of shareholders' equity.

Realized gains or losses on the sales of these debt securities are reclassified to earnings during the period in which the gain or loss is realized.

*Equity method investments*

Investee companies over which the Group has the ability to exercise significant influence, but does not have a controlling interest through investment in common shares or in-substance common shares, are accounted for using the equity method. Significant influence is generally considered to exist when the Group has an ownership interest in the voting stock of the investee between 20% and 50%. Other factors, such as representation on the investee's board of directors, voting rights and the impact of commercial arrangements, are also considered in determining whether the equity method of accounting is appropriate. For certain investments in limited partnerships, where the Group holds less than a 20% equity or voting interest, the Group may also have significant influence.

Under the equity method of accounting, the Group initially records its investment at cost and subsequently recognizes the Group's proportionate share of each equity investee's net income or loss after the date of investment into earnings and adjusts the investment carrying amount accordingly.

The Group reviews its equity method investments for impairment whenever an event or circumstance indicates that any other-than-temporary impairment has occurred. The Group considers available quantitative and qualitative evidence in evaluating potential impairment of its equity method investments. An impairment charge is recorded when the carrying amount of the investment exceeds its fair value and this condition is determined to be other-than-temporary.

*Held-to-maturity investments*

The Group holds deposits in banks that earn fixed interest rate return only if the Group holds them to maturity. The original maturities of these deposits reported as long-term investments are greater than twelve months. As the Group has the positive intent and ability to hold the deposits to maturity, they are classified as held-to-maturity and recorded at amortized cost.

*Equity securities with readily determinable fair values*

Equity securities with readily determinable fair values are measured at fair value, and any changes in fair value are recognized in the consolidated statements of operations.

*Equity securities without readily determinable fair values*

The Group elects measurement alternative to the fair value measurement for the equity securities without readily determinable fair values, under which these investments are measured at cost, less impairment, plus or minus observable price changes of an identical or similar investment of the same issuer with the fair value change recorded in the consolidated statements of operations.

The Group reviews its equity securities without readily determinable fair value for impairment at each reporting period. If a qualitative assessment indicates that the investment is impaired, the Group estimates the investment's fair value in accordance with the principles of ASC Topic 820, Fair Value Measurements and Disclosures ("ASC 820"). If the fair value is less than the investment's carrying value, the Group recognizes an impairment loss equal to the difference between the carrying value and the fair value in the consolidated statements of operations.

***Fair value***

Fair value is the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, the Group considers the principal or most advantageous market in which it would transact and it considers assumptions that market participants would use when pricing the asset or liability. Authoritative literature provides a fair value hierarchy which prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The level in the hierarchy within which the fair value measurement in its entirety falls is based upon the lowest level of input that is significant to the fair value measurement as follows:

*Level 1*

Level 1 applies to assets or liabilities for which there are quoted prices in active markets for identical assets or liabilities.

*Level 2*

Level 2 applies to assets or liabilities for which there are inputs other than quoted prices included within Level 1 that are observable for the asset or liability such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical assets or liabilities in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data.

*Level 3*

Level 3 applies to assets or liabilities for which there are unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities.

***Financial instruments***

The Group's financial instruments consist primarily of cash and cash equivalents, restricted cash, short-term investments, long-term investments except for equity method investments, other current liabilities, and long-term debt. The carrying amount of long-term debt, short-term and long-term held-to-maturity investments approximate their fair value as their interest rates are at the same level of current market yield for comparable debts and deposits. The Group carries its variable rate financial instruments, available-for-sale investments and equity securities with readily determinable fair values in long-term investments at fair value. The carrying amounts of other financial instruments, except for equity securities without readily determinable fair values approximate their fair values due to short-term maturities.

***Property and equipment, net***

Property and equipment are stated at cost and are depreciated using the straight-line method over the estimated useful lives of the assets, as follows:

---

| | |
|:---|:---|
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Category | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Estimated useful life |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Buildings | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;36-40 years |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Leasehold and buildings improvements | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Shorter of lease term or expected useful life |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Electronic and office equipment | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3-5 years |

---

Repair and maintenance costs are charged to expense as incurred, whereas the cost of renewals and betterment that extends the useful lives of property and equipment are capitalized as additions to the related assets. Retirements, sales and disposals of assets are recorded by removing the cost and accumulated depreciation from the asset and accumulated depreciation accounts with any resulting gain or loss reflected in the consolidated statements of operations.

***Intangible assets, net***

Intangible assets are amortized using the straight-line basis over the estimated useful lives as follows:

---

| | |
|:---|:---|
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Category | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Estimated useful life |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Computer software | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3 years |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;License | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5 years |

***Impairment of long-lived assets***

The Group reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may no longer be recoverable. When these events occur, the Group measures impairment by comparing the carrying value of the long-lived assets to the estimated undiscounted future cash flows expected to result from the use of the assets and their eventual disposition. If the sum of the expected undiscounted cash flow is less than the carrying amount of the assets, the Group would recognize an impairment loss based on the fair value of the assets. The Group recognized an impairment loss on its long-lived assets of nil, nil and RMB67,931 for the years ended December 31, 2023, 2024 and 2025, respectively.

***Revenue recognition***

The Group follows five steps for its revenue recognition under ASC 606, Revenue from Contracts with Customers: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract, and (v) recognize revenue when (or as) the entity satisfies a performance obligation.

The Group's revenue is reported net of discount, value added tax and related surcharges. The primary sources of the Group's revenues are as follows:

*Online education services*

For online education services, the Group provides an integrated online education service package to students, including online live streaming audio-video interactive course content, recorded previous live audio-video course content, quiz banks, online chat rooms, and educational contents. The services and goods provided in the package are highly interdependent and interrelated in the context of the contract and are only considered accessory services to the online live streaming and recorded courses which are not distinct and are not sold standalone. Therefore, the Group's integrated online education services package is accounted for as a single performance obligation. The weighted average service period for interest, professional skills and professional certification preparation courses and degree- or diploma-oriented post-secondary courses was 4 months and 16 months, respectively, for the year ended December 31, 2025.

The transaction price of the integrated online education service package is determined by the contract amount net of any discount. Students are offered a full, unconditional refund within 24 hours upon enrollment and undelivered courses are eligible for refund during the entire service period, excluding registration fees. Refund liability represents the tuition fee collected by the Group which is expected to refund back to the customers as a result of the Group's refund policy. Refund liabilities are estimated based on a historical refund ratio on a portfolio basis using the expected value method and current period experience factors, such as the anticipated cash refund that would occur in the normal course of business.

Revenues for online education services are recognized on a straight-line basis over the service period from the registration day to the day on which the service period ends.

For certain online courses, the Group provided students the right to apply for refund or cash incentive if certain pre-agreed conditions are achieved. The Group estimated the variable consideration to be earned to the extent it was probable that a significant reversal of cumulative revenue recognized would not occur when the uncertainty associated with the variable consideration was resolved and recognized revenue over time from the registration day to the day on which the service period ended on a straight-line basis. The Group's estimates of variable consideration and determination of whether to include estimated amounts in the transaction price were based largely on an assessment of the Group's anticipated performance and all information (historical, current and forecasted) that was reasonably available.

For certain online courses, the service period includes a regular period plus an extended period. The Group offers students an extended service period after the regular period if certain pre-agreed conditions are met. Based on historical passing rates and forecasted passing rates, the Group applies and categorizes the students by portfolio (1) eligible to the extended period and (2) not eligible to the extended period and estimates the portion of each portfolio. The Group recognizes the revenue on each portfolio over time from the registration day to the day on which the service is expected to end on a straight-line basis.

***Revenue recognition*** – continued

For certain online courses, the Group offers a bundled service including an integrated online education service package with insurance coverage for tuition refund. If certain refund conditions are met, students could claim the insurance equal to full or partial amount of the service fee. The Group identifies that the integrated online education service package and the insurance service are two separate performance obligations as students benefit from each service on its own and they are separately identifiable in the contract. The Group records revenue generated from online education services with insurance coverage on a gross basis as the Group is acting as the principal to fulfill all obligation and control all the services transferred to the students. The total service fee is allocated to each performance obligation based on selling prices, which are estimated based on the expected cost of satisfying each performance obligation plus an estimated margin. Revenues for integrated online education service and the insurance service are recognized over their respective service periods on a straight-line basis from the registration day to the day on which the service period ends as the students simultaneously receives and consumes the benefits provided by these two performance obligations. The Group's deferred costs represent the unamortized incremental sales commission relating to obtaining of customers contract, and the contract liability primarily consists of deferred revenue.

*Student financing*

The Group offers an installment payment option to students, under which the students obtain loans, from accredited credit sources ("Loan Companies") for the purpose of satisfying the student's tuition payment due. The borrowing student is obligated to repay the loan principal in installments over periods ranging from 3 months to 12 months to the Loan Companies, while the Group agrees with the Loan Companies to bear the student's interest expense and service fees. The Loan Companies remit the tuition to the Group for students to complete the registration. The interest expense and service fees are recorded as a reduction of the transaction price.

*Sales of goods*

The Group also generates revenues from sales of goods, primarily consisting of printed books and learning materials. Revenues are recognized when the control of the promised goods is transferred to customers, in an amount that reflects the consideration the Group expects to be entitled to in exchange for the goods.

*Other revenues*

Other revenues primarily consist of commission revenue. The Group earns commission revenue by providing referral services to third party institutions. Commission revenue is recognized at a point in time when the referred students complete registration at the third party institutions, which is when the performance obligation of the Group is satisfied.

*Deferred revenue*

Revenues related to the Group's online courses are recognized over time. Deferred revenue consists of tuition fees received from students for which services have not yet been provided to students.

***Value added taxes ("VAT")***

The Group's services are subject to VAT at the rate of 6%, and sales of goods are calculated at 13% on revenue and paid after deducting input VAT on purchases for general-VAT-payer entities in accordance with tax rule, except that certain subsidiaries were subject to a simple VAT collection method at a rate of 3%.

***Cost of revenues***

Cost of revenues consist of expenditures incurred in the generation of the Group's revenue, including but not limited to salaries and benefits paid to teachers and mentors, cost of printed books and learning materials, service fees paid to educational institutions, cooperation costs, related rental expenses, server management costs, bandwidth costs, payment processing costs, depreciations for property and equipment and amortizations for intangible assets.

***Product development expenses***

Product development expenses primarily consist of (i) salaries and benefits for innovation and development of course content, product and technology development personnel, and (ii) office rental, general expenses and depreciation and amortization expenses associated with the product development activities. The Group's product development activities primarily consist of the development and enhancement of the Group's educational content, applications and platforms. The Group has expensed all product development expenses when incurred.

***Sales commission***

The incremental sales commission relating to obtaining the customer contract and expected to be recovered is accounted for as an incremental cost of obtaining a contract and is capitalized as deferred costs when incurred. The capitalized cost is amortized in the same manner as the revenue recognized and is included in "sales and marketing expenses" in the consolidated statements of operations.

Other sales commission incurred regardless of whether the contract was obtained is recognized as an expense when incurred.

***Advertising expenditure***

Advertising expenditure, mainly including search engine marketing and mobile marketing expenses, is expensed when incurred and is included in sales and marketing expenses in the consolidated statements of operations. Advertising expenses were RMB556,088, RMB588,918 and RMB536,446 for the years ended December 31, 2023, 2024 and 2025, respectively.

***Sales and marketing expenses***

Sales and marketing expenses primarily consist of (i) salaries and benefits for sales and marketing personnel, (ii) search engine marketing and mobile marketing expenses and other advertising expenses, (iii) office rental, general expenses and depreciation and amortization expenses associated with the sales and marketing activities.

***Leases***

The Group leases administrative office spaces and enrollment centers in different cities in the PRC under operating leases. The Group determines whether an arrangement constitutes a lease at inception. The Group has lease agreements with lease and non-lease components, which are generally accounted for separately. The allocation of the consideration between the lease and the non-lease components is based on the relative stand-alone prices of lease components included in the lease contracts. Operating lease right-of-use assets and liabilities are recognized at lease commencement date based on the present value of remaining lease payments over the lease terms. The Group uses the implicit rate when readily determinable, or its incremental borrowing rate based on the information available, at the commencement date in determining the present value of lease payments. Certain leases include renewal options and/or termination options. Renewal options are included in the lease term if the Group is reasonably certain to exercise those options while options to terminate the lease are only included in the lease term if the Group is reasonably certain not to exercise those options. Lease expense is recorded on a straight-line basis over the lease term.

For short-term leases, the Group records operating lease expense in its consolidated statements of operations on a straight-line basis over the lease term.

***Government subsidies***

For the government subsidies not subject to further performance obligations or future returns, the Group records the amounts as other income when received from local government authority. Government subsidies received and recorded as other income amounted to RMB6,045 and RMB2,133 and RMB1,484 for the years ended December 31, 2023, 2024 and 2025, respectively.

***Income taxes***

Current income taxes are provided for in accordance with the laws of the relevant tax authorities. Deferred income taxes are recognized when temporary differences exist between the tax bases of assets and liabilities and their reported amounts in the financial statements. Net operating loss carry forwards and credits are applied using enacted statutory tax rates applicable to future years. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more-likely-than-not that a portion of or all of the deferred tax assets will not be realized. The impact of an uncertain income tax position is recognized at the largest amount that is more-likely-than-not to be sustained upon audit by the relevant tax authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. Interest and penalties on income taxes will be classified as a component of the provisions for income taxes.

***Comprehensive income***

Comprehensive income includes net income, foreign currency translation adjustments and unrealized loss on available-for-sale investments and is reported in the consolidated statements of comprehensive income. The Group presents the components of net income, the components of other comprehensive income/(loss) and total comprehensive income in two separate but consecutive statements.

***Net income per share***

Basic net income per share is computed by dividing net income attributable to ordinary shareholders of the Company by the weighted average number of common shares outstanding during the year. Diluted net income per share reflects the potential dilution that could occur if securities or other contracts to issue common shares were exercised into common shares. To calculate the number of shares for diluted income per share, the effect of the share options is computed using the treasury stock method.

The effect of potential issuances of shares for the share options was anti-dilutive, and therefore basic and diluted income per share were the same for the years ended December 31, 2023, 2024 and 2025.

***Share-based compensation***

Share-based compensation with employees is measured based on the grant date fair value of the equity instrument. Share-based compensation expenses, net of forfeitures, are recognized over the requisite service period based on a straight-line basis with a corresponding impact reflected in additional paid-in capital.

***Significant risks and uncertainties***

*Foreign currency risk*

RMB is not a freely convertible currency. The State Administration for Foreign Exchange, under the authority of the People's Bank of China, controls the conversion of RMB into foreign currencies. The value of RMB is subject to changes in central government policies and to international economic and political developments affecting supply and demand in the China Foreign Exchange Trading System market. The cash and cash equivalents of the Group included aggregate amounts of RMB147,737 and RMB211,175, which were denominated in RMB at December 31, 2024 and 2025, representing 29.1% and 36.7% of the cash and cash equivalents at December 31, 2024 and 2025, respectively.

*Concentration of credit risk*

Financial instruments that potentially expose the Group to significant concentration of credit risk primarily consist of cash and cash equivalents, restricted cash, short-term investments and receivables from third party payment agencies. The Group places its cash and cash equivalents, restricted cash and short-term investments in financial institutions with high credit ratings.

There are no revenues from customers which individually represent greater than 10% of the total net revenues for any year of the three years period ended December 31.

***Recently adopted accounting guidance***

In December 2023, the Financial Accounting Standards Board ("FASB") issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures ("ASU 2023-09"), which improves income tax disclosures. The amendments require the disclosure of specific categories in the rate reconciliation and additional information for reconciling items that meet a quantitative threshold. The amendments also require disaggregated information about the amount of income taxes paid, Income from continuing operations before income tax expense and Income tax expense from continuing operations. The new guidance is required to be applied either prospectively or retrospectively. This guidance is effective for the Group's fiscal years beginning after December 15, 2024. Early adoption is permitted. Beginning January 1, 2025, the Group adopted ASU 2023-09 prospectively.The adoption did not have a material impact on the consolidated financial statements, and the required disclosures are included in Note 18.

***Recently issued accounting pronouncements not yet adopted***

In November 2024, the FASB issued ASU 2024-03, "Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses". The amendments in this ASU are intended to improve financial reporting by requiring that public business entities disclose additional information about specific expense categories in the notes to financial statements at interim and annual reporting periods. For interim and annual reporting periods, an entity shall disaggregate, in a tabular format disclosure in the notes to financial statements, all relevant expense captions presented on the face of the income statement in continuing operations into the purchases of inventory, employee compensation, depreciation, amortization, and depletion. This ASU is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The amendments in this Update should be applied either (1) prospectively to financial statements issued for reporting periods after the effective date of this Update or (2) retrospectively to any or all prior periods presented in the financial statements. The Company is in the process of evaluating the impact of the adoption of this pronouncement on its consolidated financial statements.

In July 2025, the FASB issued ASU 2025-05, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets ("ASU 2025-05"), which provide (1) all entities with a practical expedient and (2) entities other than public business entities with an accounting policy election when estimating expected credit losses for current accounts receivable and current contract assets arising from transactions accounted for under Topic 606. An entity can elect a practical expedient to assume that the current conditions as of the balance sheet date will remain unchanged for the remaining life of the assets when estimating expected credit losses. ASU 2025-05 is effective for fiscal years beginning after December 15, 2025, and interim reporting periods within those fiscal years. Early adoption is permitted. This ASU should be applied prospectively. The Company is currently evaluating the impact of this new standard on its consolidated financial statements.

In December 2025, the FASB issued ASU 2025-10, Government Grants (Topic 832): Accounting for Government Grants Received by Business Entities ("ASU 2025-10"), to improve generally accepted accounting principles by establishing authoritative guidance on the accounting for government grants received by business entities. The amendments establish the accounting for a government grant received by a business entity, including guidance for (1) a grant related to an asset and (2) a grant related to income. The guidance is effective for fiscal years beginning after December 15, 2028, with early adoption permitted, and it can be applied using one of the following approaches: (1) a modified prospective approach; (2) a modified retrospective approach and (3) a retrospective approach to all government grants. The Company is currently in the process of evaluating the disclosure impact of adopting ASU 2025-10.

***Singapore***

The Company's subsidiaries, Sunlands Online Education Singapore Pte.Ltd is incorporated in Singapore and are subject to Singapore Profits Tax on the taxable income as reported in its statutory financial statements adjusted in accordance with relevant Singapore tax laws. The profits earned by Singapore entities will be taxed at 17%, with 75% of the first SGD$10,000 taxable income and 50% of the next SGD$190,000 taxable income are exempted from income tax.

***Hong Kong***

The Company's subsidiaries, Sunlands HK and FireSky Investment HK Limited are located in Hong Kong and are subject to a two-tiered income tax rate for taxable income earned in Hong Kong with effect from April 1, 2018. The first HK$2 million of profits earned by HK entity will be taxed at 8.25%, while the remaining profits will continue to be taxed at the existing 16.5% tax rate. In addition, to avoid abuse of the two-tiered income tax rate regime, each group of connected entities can nominate only one entity to benefit from the two-tiered income tax rate. No provision for Hong Kong profits tax has been made in the consolidated financial statements as it has no assessable income for the years ended December 31, 2023, 2024 and 2025.

***China***

The Group's subsidiaries, VIEs and VIEs' subsidiaries incorporated in the PRC are generally subject to a corporate income tax rate of 25%.

The Enterprise Income Tax Law (the "EIT Law") of the PRC, effective since January 1, 2008, applies a uniform 25% enterprise income tax rate to all resident enterprises in China, including foreign invested enterprises.

The local tax bureau in Guangdong exempted 40% of the EIT based on the statutory tax rate of 25% for the enterprises located in certain autonomous regions from 2018 to 2035. Therefore, Qingyuan Qisi Information Technology Consulting Co., Ltd. ("Qingyuan Qisi"), located in the region, enjoyed a preferential income tax rate of 15% in 2025 and will enjoy a rate of 15% from 2026 to 2035.

The reconciliation of the effective tax rate and the statutory income tax rate applicable to PRC operations was as follows:

Deferred taxes reflect the tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The components of deferred taxes are as follows:

As of December 31, 2025, the Company' subsidiaries, the VIEs and VIEs' subsidiaries registered in the PRC have total net operating loss carry forwards of RMB1,377,602, which would expire on various dates through December 31, 2026 to December 31, 2030.

The authoritative guidance requires that the Group recognizes the impact of a tax position in the financial statements if that position is more likely than not of being sustained upon audit by the tax authority, based on the technical merits of the position. Under PRC laws and regulations, arrangements and transactions among related parties may be subject to examination by the PRC tax authorities. If the PRC tax authorities determine that the contractual arrangements among related companies do not represent a price under normal commercial terms, they may make adjustments to the companies' income and expenses. A transfer pricing adjustment could result in additional tax liabilities. The Group did not have any significant unrecognized uncertain tax positions as of and for the years ended December 31, 2023, 2024 and 2025.

In addition, uncertainties exist with respect to how the current income tax law in the PRC applies to the Group's overall operations, and more specifically, with regard to tax residency status. The New EIT Law includes a provision specifying that legal entities organized outside of the PRC will be considered residents for Chinese income tax purposes if the place of effective management or control is within the PRC. The implementation rules to the New EIT Law provide that non-resident legal entities will be considered PRC residents if substantial and overall management and control over the manufacturing and business operations, personnel, accounting and properties, occurs within the PRC. Despite the present uncertainties resulting from the limited PRC tax guidance on the issue, the Group does not believe that the legal entities organized outside of the PRC within the Group should be treated as residents for EIT law purposes. If the PRC tax authorities subsequently determine that the Company and its subsidiaries registered outside the PRC should be deemed resident enterprises, the Company and its subsidiaries registered outside the PRC will be subject to the PRC income taxes, at a rate of 25%.

The EIT Law also imposes a withholding income tax of 10% on dividends distributed by a Foreign Investment Enterprise ("FIE") to its immediate holding company outside of the Chinese mainland, if such immediate holding company is considered as a non-resident enterprise without any establishment or place within the Chinese mainland or if the received dividends have no connection with the establishment or place of such immediate holding company within the Chinese mainland, unless such immediate holding company's jurisdiction of incorporation has a tax treaty with the Chinese mainland that provides for a different withholding arrangement. According to the arrangement between the Chinese mainland and Hong Kong Special Administrative Region on the Avoidance of Double Taxation and Prevention of Fiscal Evasion in August 2006, dividends paid by a FIE in the Chinese mainland to its immediate holding company in Hong Kong will be subject to withholding tax at a rate of no more than 5% (if the FIE satisfies the criteria for "beneficial owner" under Circular No. 9, which was issued by the STA in February 2018, and the foreign investor owns directly at least 25% of the shares of the FIE).

Before 2024, the Group did not record any dividend withholding tax on the retained earnings of its FIEs in the Chinese mainland, as the Group intended to reinvest all earnings from its FIEs in the Chinese mainland to further expand its business in the Chinese mainland, and its FIEs did not intend to declare dividends on the retained earnings to their immediate foreign holding companies.

During the year ended December 31, 2025, Wuhan Zhibo declared cash dividends of RMB38,000 to its sole shareholder, Sunlands HK and paid RMB1,904 withholding tax when the cash dividends were fully paid to its parent company.

For the years ended December 31, 2024 and 2025, the Group accrued RMB3,695 and RMB2,672 withholding tax expenses associated with its earnings expected to be distributed from its FIEs in the Chinese mainland to countries or regions other than the Chinese mainland. As of December 31, 2024 and 2025, the Group had accrued withholding tax liabilities associated with all of its earnings expected to be distributed from its FIEs in the Chinese mainland to countries or regions other than the Chinese mainland.

**20.** **COMMITMENTS AND CONTINGENCIES**

***Contingencies***

From time to time, the Group is subject to legal proceedings and claims incidental to the conduct of its business. The Group accrues the liability when the loss is probable and reasonably estimable.

**21.** **SEGMENT REPORTING**

The Group's chief operating decision maker ("CODM") has been identified as the Chief Executive Officer of the Group, who reviews financial information of operating segments when making decisions about allocating resources and assessing performance of the Group. An operating segment is a component of the Group that engages in business activities from which it may earn revenues and incur expenses, and is identified on the basis of the internal financial reports that are provided to and regularly reviewed by the Group's CODM.

For the years ended December 31, 2023, 2024 and 2025, the Group's CODM managed the Group's business activities as a single operating and reportable segment at the consolidated level. Accordingly, the Group's CODM used consolidated net income in the annual budget and forecasting process to measure segment profit or loss, allocated resources and assessed performance. Significant segment expenses were the same as those presented under the cost of revenue and operating expenses in the consolidated statements of operations. Other segment items included in consolidated net income were interest income, interest expense, other income, net and income tax expenses in the accompanying consolidated statements of operations.

The Group primarily operates in the PRC and the majority of the Group's long-lived assets are located in the PRC.

**22.** **EMPLOYEE DEFINED CONTRIBUTION PLAN**

Full time employees of the Group in the PRC participate in a government mandated defined contribution plan, pursuant to which certain pension benefits, medical care, employee housing fund and other welfare benefits are provided to employees. Chinese labor regulations require that the PRC subsidiaries of the Group make contributions to the government for these benefits based on certain percentages of the employees' salaries. The Group has no legal obligation for the benefits beyond the contributions made. The total amounts for such employee benefits, which were expensed as incurred, were RMB90,470, RMB85,184 and RMB80,870, for the years ended December 31, 2023, 2024 and 2025, respectively.

**23.** **RESTRICTED NET ASSETS**

Relevant PRC statutory laws and regulations permit payments of dividends by the Group's PRC subsidiaries only out of their retained earnings, if any, as determined in accordance with PRC accounting standards and regulations. The results of operations reflected in the financial statements prepared in accordance with U.S. GAAP differ from those reflected in the statutory financial statements of the Company's subsidiaries.

In accordance with the Regulations on Enterprises with Foreign Investment of China and their articles of association, a foreign invested enterprise established in the PRC is required to provide certain statutory reserves, namely general reserve fund, the enterprise expansion fund and staff welfare and bonus fund which are appropriated from net profit as reported in the enterprise's PRC statutory accounts, which is included in retained earnings accounts in equity section of the consolidated balance sheets. A wholly-owned foreign invested enterprise is required to allocate at least 10% of its annual after-tax profit to the general reserve until such reserve reaches 50% of its respective registered capital based on the enterprise's PRC statutory accounts. Appropriations to the enterprise expansion fund and staff welfare and bonus fund are at the discretion of the board of directors for all foreign invested enterprises. The aforementioned reserves can only be used for specific purposes and are not distributable as cash dividends. If any PRC subsidiary incur debt on its own behalf in the future, the instruments governing the debt may restrict their ability to pay dividends or make other payments to the Group. Any limitation on the ability of the PRC subsidiaries to distribute dividends or other payments to their respective shareholders could materially and adversely limit the ability to grow, make investments or acquisitions that could be beneficial to pay dividends.

Additionally, in accordance with the Company Law of the PRC, a domestic enterprise is required to provide statutory common reserve at least 10% of its annual after-tax profit until such reserve reaches 50% of its respective registered capital based on the enterprise's PRC statutory accounts. The Group's provision for the statutory common reserve is in compliance with the aforementioned requirement of the Company Law. A domestic enterprise is also required to provide for discretionary surplus reserve, at the discretion of the board of directors, from the profits determined in accordance with the enterprise's PRC statutory accounts. The aforementioned reserves can only be used for specific purposes and are not distributable as cash dividends.

Because the Group's entities in the PRC can only be paid out of distributable profits reported in accordance with PRC accounting standards, the Group's entities in the PRC are restricted from transferring a portion of their net assets to the Company. The restricted amounts include the paid-in capital and statutory reserves of the Group's entities in the PRC. The aggregate amount of paid-in capital and statutory reserves, which is the amount of net assets of the Group's entities in the PRC (mainland) not available for distribution, were RMB1,652,022 as of December 31, 2025.

On March 23, 2026, the Group entered into an agreement to transfer all of the equity interests in Guangzhou Shangzhi Side Technology Co., Ltd., a subsidiary wholly-owned by the Group, to a third party buyer for total cash consideration of RMB126,000. As of December 31, 2025, the disposed asset group primarily consisted of a building located in Guangzhou and did not meet the criteria to be classified as held for sale and continued to be accounted for as held for use. The Group is currently evaluating the impact of this transaction on its consolidated financial statements.

The condensed financial information of Sunlands Technology Group has been prepared using the same accounting policies as set out in the accompanying consolidated financial statements except that the equity method has been used to account for investments in its subsidiaries, the VIEs and VIEs' subsidiaries.

**2.** **INVESTMENTS IN SUBSIDIARIES AND VIES AND VIES' SUBSIDIARIES**

The Company, its subsidiaries, the VIEs and the VIEs' subsidiaries were included in the consolidated financial statements where the inter-company balances and transactions were eliminated upon consolidation. For purpose of the Company's stand-alone financial statements, its investments in subsidiaries, the VIEs and the VIEs' subsidiaries were reported using the equity method of accounting. The Company's share of loss/income from its subsidiaries, the VIEs and the VIEs' subsidiaries were reported as equity in earnings of its subsidiaries, the VIEs and the VIEs' subsidiaries in the condensed statements of operations.

**3.** **CONVENIENCE TRANSLATION**

The Group's business is primarily conducted in China and all of the revenues are denominated in RMB. However, periodic reports made to shareholders will include current period amounts translated into US dollars using the exchange rate as of balance sheet date, for the convenience of the readers. Translations of balances in the balance sheet, and the related statement of operations and cash flows from Renminbi ("RMB") into US dollars as of and for the year ended December 31, 2025 are solely for the convenience of the readers and were calculated at the rate of US$1.00=RMB6.9931, representing the noon buying rate set forth in the H.10 statistical release of the U.S. Federal Reserve Board on December 31, 2025. No representation is made that the RMB amounts could have been, or could be, converted, realized or settled into US$ at that rate on December 31, 2025, or at any other rate.
