On 3 June 2026, OSL Group Limited released its latest batch of corporate communications, including (i) the circular containing the notice of the forthcoming Annual General Meeting and (ii) the related proxy form.

Both the English and Chinese versions have been posted on the company website (group.osl.com) and on the HKEX news portal (hkexnews.hk). Registered shareholders who have already opted for hard-copy deliveries will receive printed materials by mail.

The board strongly promotes electronic dissemination. Shareholders may: 1. Receive email alerts with direct links to all future documents; or 2. Continue to request hard-copy English, Chinese, or bilingual versions by submitting the enclosed Change Request Form.

The completed form can be returned to the Hong Kong branch share registrar, Tricor Investor Services Limited, by post (17/F, Far East Finance Centre, 16 Harcourt Road, Hong Kong; prepaid label provided) or by email (863-ecom@vistra.com).

Responsibility for providing a functional email address rests with each registered shareholder. Until such address is supplied, the registrar will send notices of publication and any actionable communications in printed form only.

Shareholders with questions may contact Tricor’s hotline at +852 2980 1333 between 9:00 a.m. and 6:00 p.m., Monday to Friday (excluding public holidays). The notification was authorised by Executive Director and Chief Executive Officer Cui Song on behalf of the board.
