The board of directors (the “Board”) of H World Group Limited (the “Company” or “we”) is soliciting proxies for the annual general meeting of shareholders of the Company (the “AGM” or the “General Meeting”) to be held on June 27, 2025 at 10:00 a.m. (local time). The AGM will be held at No. 1299 Fenghua Road, Jiading District, Shanghai, People’s Republic of China.

You can review and download the proxy statement and the proxy form at the “Investor Relations—News & Events—AGM Summary” section of the Company’s website at https://ir.hworld.com/news-and-events/agm-summary, and website of The Stock Exchange of Hong Kong Limited at www.hkexnews.hk.

RECORD DATE, SHARE OWNERSHIP AND QUORUM

Only holders of the Company’s ordinary shares, par value US$0.00001 per share (“Ordinary Shares”) of record as of the close of business on May 9, 2025, Hong Kong time (the “Ordinary Shares Record Date”) are entitled to attend and vote at the AGM.

Holders of American Depositary Shares (“ADSs”) issued by Citibank, N.A., as depositary of the ADSs, and representing our Ordinary Shares are not entitled to attend or vote at the AGM under the Company’s amended and restated memorandum of association (the “Memorandum”) and second amended and restated articles of association (the “Articles”). Please note that any ADS holder who appears at the venue of the AGM will not be allowed to attend the AGM. Holders of ADSs as of the close of business on May 9, 2025, New York time (the “ADS Record Date”) will be able to instruct Citibank, N.A., the depositary of the ADSs and the holder of record (through a nominee) of the Ordinary Shares represented by ADSs, as to how to vote the Ordinary Shares represented by such ADSs. Citibank, N.A., as depositary of the ADSs, will endeavor, to the extent practicable and legally permissible, to vote or cause to be voted at the AGM the Ordinary Shares it holds in respect of the ADSs in accordance with the instructions which it has timely and properly received from ADS holders.

One or more holders of the Company’s ordinary shares holding no less than an aggregate one-third of all voting share capital of the Company in issue present in person or by proxy and entitled to vote at the AGM, shall be a quorum for all purposes.

VOTING AND SOLICITATION

Each Ordinary Share issued and outstanding as of the close of business on the Ordinary Shares Record Date is entitled to one vote at the AGM. Each resolution put to the vote at the AGM will be decided by poll. Where required by the Rules Governing the Listing of Securities on The Stock Exchange of Hong Kong Limited, a shareholder of the Company who has a material interest in the matter to be approved by a particular resolution will be required to abstain from voting on such resolution.

The solicitation materials are available on the Company’s website (https://ir.hworld.com), on the website of the U.S. Securities and Exchange Commission (www.sec.gov) and on the website of The Stock Exchange of Hong Kong Limited (www.hkexnews.hk).

VOTING BY HOLDERS OF ORDINARY SHARES

When proxy forms are properly dated, executed and returned by holders of Ordinary Shares to the mailing address set forth in the proxy form before 10:00 a.m., Hong Kong Time, on June 25, 2025 (the deadline for the return of such proxy forms), the Ordinary Shares represented by all properly executed proxies returned to the Company will be voted at the AGM as indicated or, if no instruction is given, the holder of the proxy will vote the Ordinary Shares in his discretion, unless a reference to the holder of the proxy having such discretion has been deleted and initialed on this Form of Proxy. Where the chairman of the AGM acts as proxy and is entitled to exercise his discretion, he is likely to vote the Ordinary Shares for the resolutions. As to any other business that may properly come before the AGM, all properly executed proxies will be voted by the persons named therein in accordance with their discretion. Where any holder of Ordinary Shares affirmatively abstains from voting on any particular resolution, the votes attaching to such Ordinary Shares will not be included or counted in the determination of the number of Ordinary Shares present and voting for the purposes of determining whether such resolution has been passed (but they will be counted for the purposes of determining the quorum, as described above).

VOTING BY HOLDERS OF ADSs

The nominee of Citibank, N.A. (the Depositary of the ADSs) is the holder of record for all the Ordinary Shares represented by the ADSs and as such the nominee is the only person who may attend and vote those Ordinary Shares at the AGM on behalf of the Depositary and the holders of ADSs.

We have requested Citibank, N.A., as Depositary of the ADSs, to distribute to all holders of record of ADSs as of the ADS Record Date, the notice of the AGM and an ADS Voting Card. Upon the timely receipt from any holders of record of ADSs of voting instructions in the manner specified, Citibank, N.A. will endeavor, to the extent practicable and legally permissible, to vote or cause to be voted the number of Ordinary Shares represented by the ADSs in accordance with such voting instructions. Under the terms of the deposit agreement for the ADSs (the “Deposit Agreement”), Citibank, N.A. will not vote or attempt to exercise the right to vote other than in accordance with such voting instructions or such deemed instructions as further described in the paragraphs below.

There is no guarantee that a holder of ADSs will receive the materials described above with sufficient time to enable such holder to return voting instructions to Citibank, N.A. in a timely manner, in which case the Ordinary Shares underlying your ADSs may not be voted in accordance with your wishes.

If an ADS voting card is missing voting instructions, Citibank, N.A. shall deem the holder of the ADSs in question to have instructed Citibank, N.A. to vote in favor of the items set forth in the ADS voting card. If an ADS Voting Card contains conflicting voting instructions as to any issue to be voted on at the AGM, Citibank, N.A. shall deem the holder of the ADSs in question to have instructed Citibank, N.A. to abstain from voting on such issue.

If no timely instructions are received by Citibank, N.A. from a holder of ADSs by 10:00 a.m., New York Time, June 18, 2025, under the terms of the Deposit Agreement, Citibank, N.A. will deem such holder of ADSs to have instructed it to give a discretionary proxy to a person designated by the Company to vote the Ordinary Shares represented by such holder’s ADSs, unless voting at the meeting is by show of hands and unless the Company has informed Citibank, N.A. that (x) the Company does not wish such proxy to be given, (y) substantial opposition exists, or (z) the rights of holders of Ordinary Shares may be materially adversely affected, in each case in accordance with the terms of the Deposit Agreement.

REVOCABILITY OF PROXIES AND ADS VOTING CARDS

Any proxy given by a holder of Ordinary Shares by means of a proxy form, and any voting instructions given by an ADS holder by means of an ADS voting card, pursuant to this solicitation may be revoked: (a) for holders of Ordinary Shares or ADSs, by submitting a written notice of revocation or a fresh proxy form or fresh ADS Voting Card, as the case may be, bearing a later date, which must be received by the deadlines for returning the proxy forms or ADS voting cards set forth above, or (b) for holders of Ordinary Shares only, by attending the AGM and voting in person.
