CSPC Pharmaceutical Group Limited has issued a notice to newly registered shareholders outlining the procedure for choosing how future corporate communications will be received. Under Hong Kong Stock Exchange listing requirements and the company’s articles of association, shareholders may receive materials either in printed form or electronically via the company’s website (www.cspc.com.hk) and the HKEx website (www.hkexnews.hk).

Key details of the notice are as follows:

• Election Process: Shareholders are requested to complete and return a reply form—by post or in person—to the company’s share registrar, Tricor Investor Services Limited. The registrar’s address is 17/F, Far East Finance Centre, 16 Harcourt Road, Hong Kong. Domestic mail can be sent postage-free using the provided mailing label.

• Default to Electronic Delivery: If a completed reply form or other response is not received by 17 October 2026, the shareholder will be deemed to have chosen the electronic version. A notification of each posting will then be sent by email or, if no email address is provided, by post.

• Switching Options: Shareholders may change their chosen communication method at any time by sending written notice to the registrar at the above address or via email to cspc1093-ecom@vistra.com. Printed copies will be supplied free of charge upon request if electronic access proves difficult.

• Availability of Documents: Both English and Chinese versions of corporate communications—including annual and interim reports, notices of meetings, circulars and proxy forms—will remain accessible on the company and HKEx websites. Printed versions can be obtained from the company or the registrar on request.

• Contact Information: Queries can be directed to the company’s hotline at +852 2980 1333 during business hours (9:00 a.m.–5:00 p.m., Monday to Friday, excluding Hong Kong public holidays).

The announcement underscores CSPC Pharmaceutical’s efforts to enhance communication efficiency and support environmental sustainability through wider adoption of electronic documentation.
