Form of Proxy for Annual General Meeting

To Be Held on June 30, 2026
(or any adjourned or postponed meeting thereof)

Introduction

This form of proxy (the “Form of Proxy”) is furnished in connection with the solicitation by the board of directors (the “Board”) of Trip.com Group Limited, a Cayman Islands company (the “Company”), of proxies from the holders of the issued and outstanding ordinary shares, par value US$0.00125 per share, of the Company (the “Ordinary Shares”) to be exercised at the annual general meeting of the Company (the “AGM”) to be held at 30 Raffles Place, #29-01, Singapore 048622 on June 30, 2026 at 9:30 a.m. (Singapore time), and at any adjourned or postponed meeting thereof, for the purposes set forth in the accompanying Notice of Annual General Meeting (the “AGM Notice”).

Holders of the Company’s Ordinary Shares at the close of business on May 29, 2026 (Hong Kong time) are entitled to notice of, and to vote at, the AGM or any adjournment or postponement thereof. Holders of the Company’s American Depositary Shares (“ADSs”) as of the close of business on May 29, 2026 (New York time) who wish to exercise their voting rights for the underlying Ordinary Shares represented by their ADSs must act directly through The Bank of New York Mellon, the depositary of the Company’s ADS program (the “Depositary”), if the ADSs are held by holders on the books and records of the Depositary, or indirectly through a bank, brokerage or other securities intermediary if the ADSs are held by any of them on behalf of holders, as the case may be. In respect of the matters requiring shareholders’ vote at the AGM, each Ordinary Share is entitled to one vote. The quorum of the AGM consists of one or more shareholders (in the case that the Company has only one shareholder of record, then that one shareholder) holding Ordinary Shares which represent, in aggregate, not less than ten per cent of the votes attaching to all issued and outstanding Ordinary Shares.

A proxy need not be a shareholder of the Company. A shareholder entitled to attend and vote at the AGM is entitled to appoint one or more proxies to attend and vote in his/her stead. 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 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. The Company does not presently know of any other business that may come before the AGM. However, if any other matter properly comes before the AGM, or any adjourned meeting thereof, which may properly be acted upon, unless otherwise indicated the proxies solicited hereby will be voted on such matter in accordance with the discretion of the proxy holders named therein. Notwithstanding the foregoing,

the Company can only use a proxy on behalf of ADS holders on matters specifically identified in the ADS voting card provided directly by the Depositary if the ADSs are held on the books and records of the Depositary, or indirectly through a bank, brokerage or other securities intermediary if the ADSs are held by any of them on behalf of holders. Any person giving a proxy has the right to revoke it at any time before it is exercised (i) by filing a duly signed revocation at the address set forth below, with a copy delivered to the Company’s office at 30 Raffles Place, #29-01, Singapore 048622, or (ii) by voting in person at the AGM.

To be valid, this Form of Proxy must be completed, signed and returned to Computershare Hong Kong Investor Services Limited at 17M Floor, Hopewell Centre, 183 Queen’s Road East, Wan Chai, Hong Kong no later than 48 hours before the time of the AGM to ensure your representation at the AGM.
