Item 4. Purpose of Transaction.

On June 6, 2023, BCPE Bridge and BCPE Stack submitted a preliminary non-binding proposal to the Company’s board of directors (the “Board”) in relation to the proposed acquisition of the Company in a going private transaction (the “Acquisition”) and proposed to acquire all of the outstanding Ordinary Shares (other than those Ordinary Shares that may be rolled over in connection with the Acquisition) at a purchase price of US$4.0 in cash per Ordinary Share, or US$8.0 in cash per ADS. The Board consists of nine directors, among which, Mr. Jonathan Jia Zhu and Mr. Zhongjue Chen are appointed by the BCPE Reporting Persons and/or their affiliates. On June 7, 2023, a special committee of the Board (the “Special Committee”) consisting of three disinterested and independent directors, namely Mr. Thomas J. Manning, Mr. Gang Yu and Mr. Weili Hong, was formed to consider and negotiate the Acquisition with BCPE Bridge and BCPE Stack.

On August 2, 2023, BCPE Bridge and BCPE Stack submitted an updated proposal, attached hereto as Exhibit B, regarding the Acquisition to the Special Committee and increased the proposed purchase price payable in the Acquisition for each Ordinary Share to US$4.3 in cash, or US$8.6 in cash for each ADS.

On August 11, 2023, the Company entered into an agreement and plan of merger (the “Merger Agreement”) with BCPE Chivalry Bidco Limited, an exempted company incorporated with limited liability under the laws of the Cayman Islands (“Parent”), an affiliate of the BCPE Reporting Persons, and BCPE Chivalry Merger Sub Limited, an exempted company incorporated with limited liability under the laws of the Cayman Islands and a wholly owned subsidiary of Parent (“Merger Sub”). Pursuant to the Merger Agreement, and subject to the terms and conditions thereof, Merger Sub will be merged with and into the Company (the “Merger”), with the Company continuing as the surviving company and becoming a wholly owned subsidiary of Parent.

Under the terms of the Merger Agreement, (a) each Ordinary Share issued and outstanding immediately prior to the effective time of the Merger (the “Effective Time”) will be cancelled in exchange for the right to receive US$4.3 per Ordinary Share in cash without interest and net of any applicable withholding taxes, less certain fees to the ADS depositary in the case of ADSs (the “Merger Consideration”), except for (i) the Rollover Shares (as defined below), (ii) Ordinary Shares held by Parent, Merger Sub, the Company or any of their subsidiaries, (iii) Ordinary Shares reserved for issuance and allocation pursuant to the Company’s 2020 Share Option Plan (the “Company Share Plan” and each option granted thereunder to purchase Ordinary Shares, a “Company Option”) (the Ordinary Shares described in clauses (i) through (iii), the “Excluded Shares”), and (iv) Ordinary Shares owned by holders who have validly exercised and not effectively withdrawn or otherwise lost their rights to dissent from the Merger pursuant to Section 238 of the Companies Act (As Revised) of the Cayman Islands (the “CICA”, and such Ordinary Shares, the “Dissenting Shares”), (b) the Excluded Shares will be cancelled without payment of any consideration from the Company therefor, (c) the Dissenting Shares will be cancelled and will entitle the former holders thereof to receive the fair value thereon determined in accordance with the provisions of Section 238 of the CICA, (d) each outstanding vested Company Option will be cancelled and converted into the right to receive an amount in cash equal to (i) the excess of the Merger Consideration over the per share exercise price of such vested Company Option, multiplied by (ii) the number of Ordinary Shares underlying such vested Company Option, and (e) each unvested Company Option will be cancelled in exchange for the right to receive an employee incentive award to replace such unvested Company Option, pursuant to terms and conditions to be determined by BCPE Chivalry Topco Limited (“Topco”), an exempted company incorporated with limited liability under the laws of the Cayman Islands and an affiliate of the BCPE Reporting Persons.

Following the consummation of the Merger, the Company will become a wholly owned subsidiary of Parent. In addition, if the Merger is consummated, the ADSs will no longer be listed on the Nasdaq Global Select Market, the Company’s obligations to file periodic reports under the Act will be terminated, and the Company will be privately held by the Investors (as defined below).

It is anticipated that approximately US$3.99 billion will be expended to complete the transactions contemplated by the Merger Agreement, including the Merger (the “Transactions”), and settle the transaction costs associated with the Transactions. The Transactions will be funded through a combination of (a) the proceeds from committed senior term loan facilities contemplated by a debt commitment letter dated June 28, 2023 (the “Debt Commitment Letter”) by and among Merger Sub, Shanghai Pudong Development Bank Co., Ltd. Lujiazui Sub-branch (上海浦东发展银行股份有限公司陆家嘴支行) and Industrial Bank Co., Ltd. Shanghai Branch (兴业银行股份有限公司上海分行) (collectively, the “Arrangers and Underwriters”), (b) the cancellation of all or a portion of the Ordinary Shares (including Ordinary Shares represented by ADSs) held by the BCPE Reporting Persons, the BCC Reporting Persons, Boloria Investments Holding B.V. (“APG”), Zeta Cayman Limited (“SK”) and Mr. Chengyan Liu (collectively, the “Rollover Shareholders” and each, a “Rollover Shareholder”, and such Ordinary Shares deemed contributed to Parent by the Rollover Shareholders, the “Rollover Shares”) at the Effective Time for no consideration from the Company and the receipt by the Rollover Shareholders of newly issued shares of Topco (each, a “Topco Share”), pursuant to the terms and subject to the conditions of the applicable Support Agreement (as defined below), and (c) the cash contributions contemplated by the equity commitment letters, each dated as of August 11, 2023 (collectively, the “Equity Commitment Letters”), by and between Parent and each of Bain Capital Asia

Fund V, L.P., an affiliate of the BCPE Reporting Persons (the “BCPE Sponsor”), and Keppel Funds Investments Pte. Ltd. (“Keppel”, together with BCPE Chivalry Newco, L.P., an affiliate of the BCPE Reporting Persons, and the Rollover Shareholders, each, an “Investor” and collectively, the “Investors”), pursuant to which each of the BCPE Sponsor and Keppel has agreed, subject to the terms and conditions thereof, to provide equity contribution in the amount of US$251,905,969 and US$91,243,684, respectively, for the purpose of funding the aggregate Merger Consideration, any other amounts required to be paid by Parent or Merger Sub in connection with the consummation of the Transactions pursuant to the Merger Agreement and other fees and expenses incurred by Parent or Merger Sub in connection with the Transactions.

Under the terms and subject to the conditions of the Debt Commitment Letter, the Arrangers and Underwriters have committed to arrange and underwrite senior term loan facilities of US$1,650,000,000 (or its RMB equivalent) to finance, among other things, a portion of the consideration payable for the Merger.

Concurrently with the execution of the Merger Agreement, the Investors entered into support agreements, dated as of August 11, 2023 (each, a “Support Agreement” and collectively, the “Support Agreements”) with Topco and Parent, whereby, among other things, subject to the terms and conditions of the applicable Support Agreement, the Investors (as applicable) have agreed to (a) vote any equity securities of the Company held by such Investors, together with any equity securities of the Company acquired by such Investors after the date of the Support Agreements, in favor of the approval of the Merger Agreement, the Merger and the other Transactions, and to take certain other actions in furtherance of the Transactions, (b) have the Rollover Shares (including Rollover Shares represented by ADSs) beneficially owned by such applicable Investors cancelled at the Effective Time for no consideration from the Company and receive newly issued Topco Shares, at or immediately prior to the Effective Time, (c) make a cash contribution in accordance with the Equity Commitment Letters and to subscribe for newly issued Topco Shares at or immediately prior to the Effective Time, and (d) act in accordance with certain terms and conditions that will govern the actions of Topco, Parent, Merger Sub and such Investors with respect to the Transactions.

Concurrently with the execution of the Merger Agreement, each of the BCPE Sponsor, BCPE Stack, BCPE Bridge, ESOP Holdco, Bridge Management (collectively “Bain Guarantors”) and Keppel executed and delivered a limited guaranty (collectively, the “Limited Guaranties”) in favor of the Company with respect to a portion of the payment obligations of Parent under the Merger Agreement for the termination fee that may become payable to the Company by Parent under certain circumstances and certain costs and expenses, as set forth in the Merger Agreement and the Limited Guaranties.

References to the Merger Agreement, the Support Agreement entered into by the Reporting Persons and BCPE Chivalry Newco, L.P., the Limited Guaranties issued and delivered by each of the Bain Guarantors, the Equity Commitment Letter issued and delivered by the BCPE Sponsor, and the Debt Commitment Letter are qualified in their entirety by reference to the Merger Agreement, the Support Agreement entered into by the Reporting Persons and BCPE Chivalry Newco, L.P., the Limited Guaranties issued and delivered by each of the Bain Guarantors, the Equity Commitment Letter issued and delivered by the BCPE Sponsor, and the Debt Commitment Letter, copies of which are attached hereto as Exhibits C, D, E, F and G, and incorporated herein by reference in their entirety.

Other than as described above, the Reporting Persons do not currently have any plans or proposals that relate to, or would result in, any of the matters listed in Items 4(a)-(j) of Schedule 13D, although, depending on the factors discussed herein, the Reporting Persons may change their purpose or formulate different plans or proposals with respect thereto at any time.

Item 5. Interest in Securities of the Issuer.

(a)-(b)

The responses of each Reporting Person to Rows (7) through (13), including the footnotes thereto, of the cover pages of this Schedule 13D and Item 2 above are hereby incorporated by reference in this Item 5.

As a result of entering into the Support Agreements, the BCPE Reporting Persons and BCC Reporting Persons may be deemed to be members of a “group” with AGP, SK and Mr. Chengyan Liu (collectively, the “Other Rollover Shareholders”) pursuant to Section 13(d) of the Act, who are separately reporting beneficial ownership on Schedules 13D. As of August 11, 2023, APG beneficially owns 64,506,034 Class A Ordinary Shares, SK beneficially owns 55,290,887 Class A Ordinary Shares, and Mr. Chengyan Liu beneficially owns 32,018,466 Class A Ordinary Shares represented by 16,009,233 ADSs.

The rights of the holders of the Class A Ordinary Shares and Class B Ordinary Shares are substantially identical, except with respect to voting and conversion rights. Each Class A Ordinary Share is entitled to one vote, and each Class B Ordinary Share is entitled to 15 votes and 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 under any circumstances. In addition, all of the Class B Ordinary Shares held by the BCC Reporting Persons will automatically and immediately convert into an equal number of Class A Ordinary Shares on the earlier of (i) such date when the number of Ordinary Shares held by them and their affiliates (taken as a whole) falls below 10% of the Company’s aggregate number of Ordinary Shares then outstanding and (ii) October 2, 2025.

Accordingly, the Reporting Persons and the Other Rollover Shareholders, as a group, would collectively own 481,464,108 Class A Ordinary Shares in the aggregate, representing 154,802,607 Class A Ordinary Shares (including 35,005,686 Class A Ordinary Shares represented by 17,502,843 ADSs) and 326,661,501 Class A Ordinary Shares issuable upon conversion of 326,661,501 Class B Ordinary Shares held by the group. Such aggregate ownership represents 65.67% of the outstanding Class A Ordinary Shares and 95.26% of the total voting power of the Ordinary Shares (Class A Ordinary Shares and Class B Ordinary Shares, which vote together) as of August 11, 2023.

However, each Reporting Person expressly disclaims beneficial ownership of the Class A Ordinary Shares beneficially owned (or deemed to be beneficially owned) by any of the Other Rollover Shareholders and neither the filing of this Schedule 13D nor any of its contents shall be deemed to constitute an admission that any of the Reporting Persons beneficially owns any Class A Ordinary Shares that are beneficially owned (or deemed to be beneficially owned) by any of the Other Rollover Shareholders. The Reporting Persons are only responsible for the information contained in this Schedule 13D and assume no responsibility for information contained in the Schedules 13D filed by the Other Rollover Shareholders. The filing of this Schedule 13D shall not be construed as an admission that any of the Reporting Persons is, for purposes of Section 13(d) or 13(g) of the Act or for any other purpose, the beneficial owner of any securities (other than the securities directly held by such Reporting Person) covered by this Schedule 13D.

(c)	Except as disclosed in this Schedule 13D, none of the Reporting Persons has effected any transaction in the Ordinary Shares during the past 60 days.

(d)	Except as disclosed in this Schedule 13D, to the best knowledge of the Reporting Persons, no other person has the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the Ordinary Shares beneficially owned by any of the Reporting Persons.

(e)	Not applicable.

Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.

The information disclosed under Item 4 above is hereby incorporated by reference into this Item 6.

Except as described above or elsewhere in this Schedule 13D or incorporated by reference in this Schedule 13D, there are no contracts, arrangements, understandings or relationships (legal or otherwise) between the Reporting Persons or, to the best of their knowledge, any other person with respect to any securities of the Company, including, but not limited to, transfer or voting of any securities, finder’s fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or losses, or the giving or withholding of proxies.
