A shareholder entitled to attend and vote at the EGM may appoint one or more proxies to attend and vote in his/her stead. However, the relevant proxy form must specify the class and number of Shares represented by each proxy. Shareholders attending in person or by proxy may cast one vote for each Share held. A proxy need not be a shareholder of the Company but must attend the EGM in person to represent the relevant shareholder. The instrument appointing a proxy must be in writing under the hand of a shareholder or his/her attorney duly authorized in writing. If the shareholder is a corporation, that instrument must be executed either under its common seal or under the hand of its director(s) or duly authorized attorney. If that instrument is signed by an attorney of the shareholder, the power of attorney authorizing that attorney to sign or other authorization document must be notarized. To be valid, the proxy form and, if such proxy form is signed by a person on behalf of the appointer pursuant to a power of attorney or other authority, a notarially certified copy of that power of attorney or other authority (if any), must be delivered by the Shareholders not less than 24 hours before the time appointed for holding the EGM or any adjournment thereof (i.e. before 10:00 a.m. on Tuesday, April 7, 2026) to the Company's H Share Registrar, Tricor Investor Services Limited, at 17/F, Far East Finance Centre, 16 Harcourt Road, Hong Kong (for H Shareholders), or to the Company's headquarter and principal place of business in the PRC at No. 101-124, 1/F, Building N6, BBMG Intelligent Manufacturing Workshop, No. 27 Xisanqi Jiancaicheng Middle Road, Haidian District, Beijing, PRC (for holders of Domestic Unlisted Shares/Unlisted Foreign Shares). 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 he/she so wishes. In such event, the instrument appointing a proxy shall be deemed to be revoked.
