On 29 April 2026, Prinx Chengshan Holdings Limited announced that the English and Chinese versions of its latest Annual Report, Circular and Proxy Form are now available on both the company’s website (www.prinxchengshan.com) and the HKEX website (www.hkexnews.hk).

To enhance communication efficiency, Prinx Chengshan is asking registered shareholders to submit a valid email address. By completing and returning the “Provision of Email Address Form” to the Hong Kong share registrar, Tricor Investor Services Limited (“Vistra”), or by emailing 1809-ecom@vistra.com, shareholders will receive electronic notifications whenever new corporate communications are posted online.

Key operational details: • Deadline/Timing – Forms may be returned by post to Vistra at 17/F, Far East Finance Centre, 16 Harcourt Road, Hong Kong, or by email at any time. • Responsibility – Shareholders must ensure the email address provided is functional; the company will deem delivery successful if no “non-delivery” reply is received. • Scope of documents – Corporate communications encompass directors’ reports, annual and interim reports (and any summaries), meeting notices, listing documents, circulars, reply slips and proxy forms.

Enquiries can be directed to Vistra’s hotline at (+852) 2980 1333 from 9:00 a.m. to 6:00 p.m. (Hong Kong time) on business days or via the dedicated email address. Prinx Chengshan states that all personal data collected will be used solely for verification, notification and record-keeping purposes in line with the Personal Data (Privacy) Ordinance.
