REVISIONS TO THE CONTENTS OF THE NOTICE OF THE EXTRAORDINARY GENERAL MEETING AND THE PROXY FORM

References are made to the circular (the "Circular"), notice (the "Original Notice") and the proxy form (the "Original Proxy Form") of extraordinary general meeting of SICC Co., Ltd. (the "Company") all dated 15 October 2025, which set out the time and venue of the extraordinary general meeting of the Company (the "EGM") and contain the resolutions to be proposed at the EGM for consideration of the shareholders of the Company (the "Shareholders"). Unless otherwise defined, capitalized terms used in this announcement shall have the same meanings as those defined in the Circular.

The Company hereby announces that there are revisions to the contents of Original Notice and the Original Proxy Form to the effect that the proposed ordinary resolution numbered 2 therein (in relation to the proposed amendments to the nine Governance Policies) will be considered and, if thought fit, be passed as nine standalone ordinary resolutions of the Company.

In this connection, a revised notice of the EGM (the "Revised Notice") together with a revised proxy form (the "Revised Proxy Form") for use at the EGM will be despatched to the Shareholders on 23 October 2025 and also be available on the website of the Company at www.sicc.cc and on the website of The Stock Exchange of Hong Kong Limited at www.hkexnews.hk.

Save for disclosed above, all other content of the Original Notice, the Original Proxy Form and other matters relating to the EGM remain unchanged. For details of other resolutions to be considered and approved at the EGM, eligibility for attending the EGM, registration procedures, closure of register of members and other relevant matters, please refer to the Circular and the Original Proxy Form. This announcement should be read in conjunction with the Circular and the Revised Notice.

Any Shareholder who intends to appoint a proxy to attend the EGM but has not yet lodged the Original Proxy Form is required to complete and return the Revised Proxy Form in accordance with the instructions printed thereon. In such case, the Original Proxy Form

---

should not be lodged with the Company. For the holders of H Shares, the Revised Proxy Form shall be lodged with the Company's H Share Registrar, Computershare Hong Kong Investor Services Limited, at Shop 1712-1716, 17/F, Hopewell Centre, 183 Queen's Road East, Wan Chai, Hong Kong. The Revised Proxy Form must be lodged not less than 24 hours before the time scheduled for holding the EGM (or any adjournment thereof) (the "Closing Time").

Any Shareholder who has already lodged the Original Proxy Form with the Company should note that:

(i) if no Revised Proxy Form is lodged with the Company, the Original Proxy Form will be treated as a valid proxy form lodged by him/her, if correctly completed. The proxy so appointed pursuant to the Original Proxy Form will be entitled to vote in accordance with the instructions given by the Shareholders or at his/her discretion (if no such instructions) on any resolutions properly put to the EGM including the ordinary resolutions 2.1 to 2.9 as set out in the Revised Notice.

(ii) if the Revised Proxy Form is lodged with the Company before the Closing Time, the Revised Proxy Form will be treated as a valid proxy form lodged by the Shareholder if correctly completed.

(iii) if the Revised Proxy Form is lodged after the Closing Time, the Revised Proxy Form will be treated as invalid. The Original Proxy Form previously lodged by the Shareholder will also be revoked. The purported proxy so appointed by invalid or revoked proxy form (whether appointed under the Original Proxy Form or the Revised Proxy Form) will not be counted in any poll which will be taken on a proposed resolution. Accordingly, Shareholders are advised not to lodge the Revised Proxy Form after the Closing Time. In such case, if such Shareholders wish to vote at the meeting, they will have to attend in person and vote at the meeting by themselves.

Shareholders are reminded that completion and delivery of the Original Proxy Form and/or the Revised Proxy Form will not prejudice the Shareholders from attending and voting at the EGM in person or at any adjournment thereof (as the case may be) should they so wish and, in such event, the instrument appointing a proxy shall be deemed to be revoked.
