In order to be eligible to attend and vote at the forthcoming EGM, holders of H Shares must lodge all completed transfer documents accompanied by the relevant share certificates with the Company's H Share Registrar, Computershare Hong Kong Investor Services Limited at Shop 1712-1716, 17th Floor, Hopewell Centre, 183 Queen's Road East, Wan Chai, Hong Kong on or before 4:30 p.m. on Thursday, December 11, 2025.

3. Shareholders who are entitled to attend and vote at the EGM may appoint one or more proxies to attend and vote on their behalf. A proxy need not be a Shareholder. If more than one proxy is appointed, the number and class of Shares in respect of which each such proxy is so appointed shall be specified in the appointment of the proxy.

4. The form of proxy must be signed by the Shareholder or by an authorized person appointed by the Shareholder in writing. If the Shareholder is a legal person, it must be stamped with the seal of the legal person or signed by a director or duly authorized attorney. If the form is signed by an attorney of the Shareholder, the power of attorney authorizing that attorney to sign or other authorisation document must be notarised.

5. In order to be valid, in the case of holders of H Shares, the form of proxy, and if the form of proxy is signed by a person under a power of attorney or other authorization document on behalf of the appointer, a notarially certified copy of that power of attorney or other authorization document, must be deposited with the H Share registrar of the Company, Computershare Hong Kong Investor Services Limited, at 17M Floor, Hopewell Centre, 183 Queen's Road East, Wan Chai, Hong Kong not less than 24 hours before the time appointed for holding the EGM.

In case of registered joint holders of any Shares, any one of the registered joint holders can vote on such Shares at the EGM in person or by proxy as if he/she is the only holder entitled to vote. If more than one registered joint holders attend the EGM in person or by proxy, only the vote of the person whose name appears first in the register of members of the Company relating to such Shares (in person or by proxy) will be accepted as the sole and exclusive vote of the joint holders.

Completion and return of the form of proxy will not preclude a Shareholder from attending and voting in person at the EGM or any adjournment thereof should he/she/it so wish. In this case, the power of attorney will be deemed to have been revoked.

1. The EGM is expected to last for no more than half a day. Shareholders or their proxies attending the EGM are responsible for their own transportation and accommodation expenses.

2. All times refer to Hong Kong local time, except as otherwise stated.
