Holders of H Shares and domestic shares whose names appeared on the register of members of the Company as at Tuesday, 23 December 2025 shall be entitled to attend and vote at the EGM. Holders of H Shares of the Company who intend to attend and vote at the EGM must lodge all transfer documents accompanied by the relevant H Share certificates with the Company's H Share registrar, Computershare Hong Kong Investor Services Limited, at Shops 1712–1716, 17th Floor, Hopewell Centre, 183 Queen’s Road East, Wanchai, Hong Kong no later than 4:30 p.m. on Wednesday, 17 December 2025 for registration.

2. A shareholder entitled to attend and vote at the EGM may appoint one or more proxies to attend and vote in his/her stead. A proxy need not be a shareholder of the Company but must attend the EGM in person to represent the relevant shareholder.

3. The instrument appointing a proxy must be in writing under the hand of a shareholder or his attorney duly authorised in writing. If the shareholder is a corporation, the instrument must be executed either under its common seal or under the hand of its director(s) or duly authorised attorney. If the instrument is signed by an attorney of the shareholder, the power of attorney authorising that attorney to sign, or other documents of authorisation, must be notarised.

4. In order to be valid, the proxy form together with the notarised power of attorney or other documents of authorisation (if any) must be deposited at the secretariat of the board of directors of the Company at 5 Fuchengmen North Street, Xicheng District, Beijing, the PRC for holders of domestic shares and at the Company's H Share registrar, Computershare Hong Kong Investor Services Limited, at 17M Floor, Hopewell Centre, 183 Queen’s Road East, Wanchai, Hong Kong for holders of H shares not less than 24 hours before the time stipulated for convening the EGM (or any adjournment thereof) (as the case may be). Completion and return of a proxy form will not preclude a shareholder from attending and voting in person at the EGM (or any adjournment thereof). If no direction is given, the proxy will be entitled to vote or abstain as he or she thinks fit.

5. The EGM is estimated to last for about half a day. Shareholders or their proxies who attend the EGM (or any adjournment thereof) shall bear their own travelling and accommodation expenses. Shareholders or their proxies shall produce their identity documents when attending the EGM (or any adjournment thereof).
