Pursuant to Article 89(g)(i) of the Articles of Association, Ms. Ni Li, Mr. Yi Xu and Mr. Feng Li will retire as Directors by rotation, and all of them, being eligible, will offer themselves for re-election as Directors (the “Nominees”) at the AGM.

Biographical and further details about the proposed re-election of the three Directors mentioned above are set out in Appendix I to this circular.

Overview

At the annual general meeting of the Company held on June 28, 2024, the Directors were given a general mandate to allot, issue and deal with Shares. Such mandate, to the extent not utilized by the date of the AGM, will lapse at the conclusion of the AGM.

Share repurchase mandate

In order to give the Company the flexibility to repurchase Class Z Ordinary Shares and/or ADSs on-market if and when appropriate and in accordance with Rule 10.06(1)(b) of the Listing Rules, an ordinary resolution will be proposed at the AGM to approve the grant of the Share Repurchase Mandate to the Directors to repurchase Class Z Ordinary Shares and/or ADSs not exceeding 10% of the number of issued Shares (excluding Treasury Shares) as at the date of passing of such ordinary resolution. As at the Latest Practicable Date, the Company had a total of 417,986,501 issued and outstanding Shares. Subject to the passing of relevant ordinary resolution and assuming that the number of issued Shares remains unchanged following the Latest Practicable Date and prior to the date of the AGM, the maximum number of Class Z Ordinary Shares and/or ADSs which may be repurchased pursuant to the Share Repurchase Mandate as at the date of grant will be 41,798,650 Class Z Ordinary Shares and/or ADSs.

The Share Repurchase Mandate shall be effective from the date of the passing of the relevant resolution at the AGM until the earlier of: (a) the conclusion of the next annual general meeting of Shareholders unless, by an ordinary resolution passed at that meeting, the Share Repurchase Mandate is renewed, either unconditionally or subject to conditions; or (b) its revocation or variation by an ordinary resolution of the Shareholders in a general meeting.

If the Company repurchases Class Z Ordinary Shares and/or ADSs pursuant to the Share Repurchase Mandate, the Company may (i) cancel the repurchased Shares and/or (ii) hold such Shares as Treasury Shares, subject to market conditions and the Group’s capital management needs at the relevant time of the repurchases. Any sale or transfer of such Treasury Shares will be subject to the Share Issue Mandate as set out in the next proposal and made in accordance with the applicable laws and regulations, including the Listing Rules.

An explanatory statement required by the Listing Rules to be sent to all Shareholders in connection with the Share Repurchase Mandate is set out in Appendix II to this circular.

Share issue mandate

In order to give the Company the flexibility to issue Class Z Ordinary Shares (including any sale or transfer of Treasury Shares) and/or ADSs if and when appropriate and in accordance with Rule 13.36 of the Listing Rules, an ordinary resolution will be proposed at the AGM to approve the granting of a share issue mandate to the Directors to issue, allot or deal with unissued Class Z Ordinary Shares (including any sale or transfer of Treasury Shares) and/or ADSs not exceeding 20% of the total number of issued Shares (excluding Treasury Shares) as at the date of passing of such ordinary resolution. As at the Latest Practicable Date, the Company had a total of 417,986,501 issued and outstanding Shares. Subject to the passing of the relevant ordinary resolution and assuming that the number of issued Shares remains unchanged following the Latest Practicable Date and prior to the date of the AGM, the Directors will be authorized to issue (or sell or transfer out of treasury) a maximum of 83,597,300 Class Z Ordinary Shares under the Share Issue Mandate.

The Share Issue Mandate shall be effective from the date of the passing of the relevant resolution at the AGM until the earlier of: (a) the conclusion of the next annual general meeting of Shareholders unless, by an ordinary resolution passed at that meeting, the Share Issue Mandate is renewed, either unconditionally or subject to conditions; or (b) its revocation or variation by an ordinary resolution of the Shareholders in a general meeting.

The Board proposes to re-appoint PricewaterhouseCoopers and PricewaterhouseCoopers Zhong Tian LLP as Hong Kong and U.S. auditors of the Company for the year ending December 31, 2025 and to hold the office until the conclusion of the next annual general meeting of the Company.

APPENDIX I   PARTICULARS OF DIRECTORS PROPOSED TO BE RE-ELECTED

The Nominating and Corporate Governance Committee has reviewed the structure and composition of the Board, the confirmations and disclosures of the Nominees, the educational background, professional qualifications, skills, knowledge, industry experience, time commitment and contributions of the Nominees with reference to the nomination principles and criteria set out in the Company’s board diversity policy and the independence of the independent non-executive Director. Mr. Feng Li, being an independent non-executive Director proposed to be re-elected, has confirmed his independence with reference to the factors set out in Rule 3.13 of the Listing Rules. The Nominating and Corporate Governance Committee and the Board have conducted assessment on his independence and considered that Mr. Feng Li is independent in accordance with the independence guidelines set out in the Listing Rules, and are satisfied with the Nominees’ contribution to the Company, which will continue to bring valuable business experience and extensive industry insights to the Board for its effective functioning and diversity. The Nominating and Corporate Governance Committee and the Board therefore recommended the re-election of all of the Nominees, including the aforesaid independent non-executive Director, at the AGM.

Each of the Nominees has entered into a director agreement with the Company on October 3, 2022 for an initial term of three years, subject to re-election at the annual general meeting of the Company in accordance with the Articles of Association, until terminated in accordance with the agreement.

Ms. Ni Li, being a Director and Chief Operating Officer of the Company, is entitled to receive an annual salary and discretionary bonus in a total amount of approximately RMB2.7 million and may also be entitled to share-based compensation subject to the discretion of the Board which is determined by the Board with reference to her duties and responsibilities with the Group, the Company’s remuneration policy and the performance of the Group. Mr. Yi Xu, being a Director and President of the Company, is entitled to receive an annual salary and discretionary bonus in a total amount of approximately RMB1.1 million and may also be entitled to share-based compensation subject to the discretion of the Board which is determined by the Board with reference to his duties and responsibilities with the Group, the Company’s remuneration policy and the performance of the Group. Mr. Feng Li, being an independent Director, is entitled to share-based compensation subject to the discretion of the Board which is determined by the Board with reference to his duties and responsibilities with the Group. Save as disclosed herein, each of the Nominees is not entitled to any director’s fee in such person’s capacity as a Director or any other remuneration for the directorships held within the Group other than the Company.

As of the Latest Practicable Date, Ms. Ni Li had interests or was deemed to be interested in 3,000,000 Class Z Ordinary Shares and 7,200,000 Class Y Ordinary Shares of the Company, each in a long position, within the meaning of Part XV of the SFO.

APPENDIX II   EXPLANATORY STATEMENT ON THE SHARE REPURCHASE MANDATE

The following is an explanatory statement required by Rule 10.06(1)(b) of the Listing Rules to be sent to the Shareholders to enable them to make a reasonably informed decision on whether to vote for or against the ordinary resolution with respect to the Share Repurchase Mandate to be proposed at the AGM.

As at the Latest Practicable Date, the Company had a total of 417,986,501 issued and outstanding Shares.

Subject to the passing of the ordinary resolution with respect to the Share Repurchase Mandate to be proposed at the AGM, and on the basis that the Company’s total issued share capital remains unchanged from the Latest Practicable Date to the AGM date, the Directors would be authorized under the Share Repurchase Mandate to repurchase up to 41,798,650 Class Z Ordinary Shares and/or ADSs, representing 10% of the Company’s total issued share capital (excluding Treasury Shares), during the Share Repurchase Mandate period.

The Directors believe that it is in the best interests of the Company and Shareholders to have a general authority from Shareholders to enable the Company to purchase Class Z Ordinary Shares and/or ADSs in the market. The repurchases may, depending on market conditions and funding arrangements at the time, lead to an enhancement of the net asset value per Class Z Ordinary Share and/or ADS and/or its earnings per Class Z Ordinary Share and/or ADS.

The Directors would only exercise the power to repurchase in circumstances where they consider that the repurchases would be in the best interest of the Company and Shareholders.

Repurchases of Class Z Ordinary Shares and/or ADSs will be funded from the Company’s internal resources, which includes funds legally available for such purposes in accordance with the Articles of Association in effect from time to time, the Listing Rules, and applicable laws and regulations in the Cayman Islands, Hong Kong and elsewhere (as the case may be).

Based on the current level of trading price of the Company’s Shares and ADSs, the Directors believe that there may not be a material adverse impact on the working capital or gearing position of the Company (as compared with the position disclosed in the audited accounts contained in the Company’s annual report for the year ended December 31, 2024) in the event that the Share Repurchase Mandate was to be carried out in full at any time during the proposed repurchase period. The Directors do not intend to exercise the Share Repurchase Mandate to such an extent as would, in the circumstances, have a material adverse effect on the Company’s working capital requirements or gearing levels that, in the opinion of the Directors, are from time to time appropriate for the Company.

— 10 —

APPENDIX II   EXPLANATORY STATEMENT ON THE SHARE REPURCHASE MANDATE

If, on the exercise of the power to repurchase Class Z Ordinary Shares and/or ADSs pursuant to the Share Repurchase Mandate, a Shareholder’s proportionate interest in the Company’s voting right increases, this increase will be treated as an acquisition of voting rights for the purposes of the Takeovers Code. Accordingly, a Shareholder, or a group of Shareholders acting in concert (as defined in the Takeovers Code) could obtain or consolidate control of the Company and become obliged to make a mandatory offer in accordance with Rule 26 of the Takeovers Code.

As at the Latest Practicable Date, to the best knowledge and belief of the Directors, the WVR Beneficiaries were Mr. Rui Chen, Ms. Ni Li and Mr. Yi Xu, who beneficially own a total of 82,366,214 Class Y Ordinary Shares, representing a total of 71.05% of the voting rights in the Company with respect to Shareholders’ resolutions relating to matters other than the Reserved Matters (excluding 3,274,916 Class Z Ordinary Shares issued and reserved for future issuance upon the exercise or vesting of awards granted under the Company’s share incentive plans).

Pursuant to Rule 8A.15 of the Listing Rules, in the event that the Directors exercise the Share Repurchase Mandate, the WVR Beneficiaries must reduce their weighted voting rights in the Company proportionately through conversion of a proportion of their shareholding into Class Z Ordinary Shares, if the reduction in the number of Shares in issue would otherwise result in an increase in the proportion of Class Y Ordinary Shares. As such, to the best knowledge and belief of the Directors, the exercise of the Share Repurchase Mandate is not expected to give rise to an obligation of the WVR Beneficiaries to make a mandatory offer under the Takeovers Code. The Directors have no present intention to repurchase the Shares to the extent that will trigger the obligations under the Takeovers Code to make a mandatory offer. The Directors are not aware of any other consequences which may arise under the Takeovers Code as a result of any purchase by the Company of its Shares.

In addition, the Directors do not propose to repurchase Shares and/or ADSs which would result in less than the relevant prescribed minimum percentage of Shares in public hands as required by the Stock Exchange.

— 11 —

APPENDIX II   EXPLANATORY STATEMENT ON THE SHARE REPURCHASE MANDATE

Set out below are the highest and lowest prices at which the Class Z Ordinary Shares traded on the Stock Exchange during each month in the previous 12 months and until the Latest Practicable Date:

During the six months preceding the Latest Practicable Date, the Company has repurchased a total of 839,167 ADSs (representing 839,167 Class Z Ordinary Shares) on the Nasdaq as follows:

Note: The Class Z Ordinary Shares underlying the ADSs repurchased were pending cancellation as at the Latest Practicable Date.

— 12 —

APPENDIX II   EXPLANATORY STATEMENT ON THE SHARE REPURCHASE MANDATE

On December 2, 2024 (New York Time), the Company repurchased US$419,107,000 principal amount of its 0.50% Convertible Senior Notes due 2026 (which were convertible into 4,460,095 ADSs before the repurchase based on the initial conversion rate) surrendered by the noteholders pursuant to the terms of these notes at the aggregate cash purchase price of US$419,107,000 (or approximately US$93.97 per ADS), while there were no actual ADSs repurchased. Please refer to the Company’s overseas regulatory announcements dated October 21, 2024 and November 29, 2024, as well as the next day disclosure return dated December 3, 2024 and the monthly return dated January 8, 2025 for details.

None of the Directors, nor, to the best of the Directors’ knowledge having made all reasonable enquiries, any of their close associates (as defined in the Listing Rules), has any present intention, in the event that the Share Repurchase Mandate is approved, to sell any Shares to the Company.

No core connected person (as defined in the Listing Rules) has notified the Company that he/she/it has a present intention to sell Shares to the Company if the Share Repurchase Mandate is exercised or has undertaken not to sell any of the Shares held by them to the Company, in the event that the Company is authorized to make purchases to the Shares.

The Directors will exercise the power of the Company to make repurchases of Class Z Ordinary Shares and/or ADSs pursuant to the Share Repurchase Mandate in accordance with the Articles of Association, the Listing Rules and the applicable laws of the Cayman Islands.

The Directors confirm that to the best of their knowledge and belief, neither the explanatory statement nor the proposed repurchase of Shares pursuant to the Share Repurchase Mandate has any unusual features.

Subject to the applicable requirements under the Listing Rules, the Company may cancel the repurchased Shares following settlement of any such repurchase or hold them as Treasury Shares, subject to market conditions and the Group’s capital management needs at the relevant time of the repurchases. If the Company decides to hold the repurchased Shares as Treasury Shares, the Company will, upon completion of the Share repurchase, withdraw these repurchased Shares from CCASS and register the Treasury Shares in the Company’s name.

The Company may re-deposit its Treasury Shares into CCASS only if it has an imminent plan to resell them on the Stock Exchange, and it should complete the resale as soon as possible. For any Treasury Shares deposited with CCASS pending resale on the Hong Kong Stock Exchange, the Company shall (i) procure its broker not to give any instructions to Hong Kong Securities Clearing Company Limited to vote at general meetings for the Treasury Shares deposited with CCASS pending resale; and (ii) in the case of dividends or distributions, withdraw the Treasury Shares from CCASS, and either re-register them in the Company’s name as Treasury Shares or cancel them, in each case before the record date for the dividends or distributions, or take any other measures to ensure that it will not exercise any Shareholders’ rights or receive any entitlements which would otherwise be suspended under the applicable laws if those Shares were registered in its own name as Treasury Shares.

Holders of Treasury Shares (if any) shall abstain from voting on matters that require Shareholders’ approval at the Company’s general meetings.
