Notes:

1. Details of the above additional resolution are set out in the supplemental circular of the Company dated 10 June 2026 (the “Supplemental Circular”).

2. The First Notice and the accompanying First Form of Proxy were published on the websites of the Company and the Stock Exchange on 3 June 2026 for downloading. The Supplemental Circular and this Supplemental Notice are accompanied by a supplemental proxy form applicable to the AGM incorporating the above additional resolution (the “Supplemental Form of Proxy”), which supplements the First Form of Proxy. The Supplemental Form of Proxy will not affect the validity of a properly completed First Form of Proxy. If you have validly appointed a proxy to attend and act on your behalf at the AGM but have not completed and returned the Supplemental Form of Proxy, your proxy will be entitled to vote at his/her discretion on the additional resolution set out in the Supplemental Notice to the AGM on your behalf. If you have not completed and returned the First Form of Proxy but have completed and returned the Supplemental Form of Proxy and validly appointed a proxy to attend and act on your behalf at the AGM, your proxy will be entitled to vote at his/her discretion on the resolutions set out in the First Notice to the AGM on your behalf unless otherwise instructed.

3. Each Shareholder who is entitled to attend and vote at the AGM may appoint one or more proxies to attend and vote on behalf of him/her. A proxy needs not to be a Shareholder of the Company.

4. In order to be valid, the instrument appointing a proxy together with the power of attorney or other authority, if any, under which it is signed, or a notarially certified copy of such power of attorney or authority, should be completed and deposited at the liaison office of the Company in Beijing (for Domestic Shareholders) or the Registrar of the Company (for H Shareholders), at least 24 hours before the AGM or any adjourned meeting thereof. Completion and return of the Supplemental Form of Proxy will not preclude a Shareholder from attending in person and voting at the AGM or any adjournment thereof should he/she so wish. If the Shareholders or their proxies choose to attend the meeting in person, please ensure that the identity information and contact telephone number are properly completed in the Supplemental Form of Proxy so that the Company can arrange for the identity verification registration required to enter the venue in advance for you, or contact you urgently in case of any emergency.

5. In case of joint shareholdings and the Shareholder or the proxy attending the AGM is more than one person, the vote of the senior joint Shareholder who tenders a vote, whether in person or by proxy, will be accepted to the exclusion of the votes of the other joint Shareholder(s) and for this purpose seniority will be determined by the order in which the names appear in the register of members of the Company in respect of the joint shareholdings.

For details of the other resolutions to be submitted to the AGM for consideration and approval, eligibility to attend the AGM, registration procedures, closure of the register of members and other related matters, please refer to the First Circular and the First Notice.
