Biosino Bio-Technology and Science Incorporation has dispatched its AGM circular, detailing resolutions to be tabled on 28 April 2026 in Beijing. Key items include:

• General share issue mandate: The board will seek authority to allot, issue or deal with additional shares— including any sale or transfer of treasury shares—of up to 20% of the company’s issued share capital (excluding treasury shares) as at the AGM date. Based on the 144.71 million shares in issue on 31 March 2026, the mandate would permit issuance of up to 28.94 million new shares. The mandate will remain valid until the next AGM, the statutory deadline for holding it, or its earlier revocation.

• Routine business: Shareholders will vote on the 2025 directors’ report, the audited consolidated financial statements for the year ended 31 December 2025, the 2025 final financial report and the 2026 budget.

• Auditor re-appointment: The board proposes re-engaging BDO China Shu Lun Pan Certified Public Accountants LLP as PRC auditor and BDO Limited as international auditor until the conclusion of the next AGM, with remuneration to be set by the board.

Logistics: The AGM will be held at the company’s Beijing headquarters (No. 27 Chaoqian Road, Changping District) at 10:00 a.m. Shareholders must lodge H-share transfer documents by 4:30 p.m. on 22 April 2026; the registers of members for both H and domestic shares will be closed from 23–28 April 2026. All AGM resolutions will be decided by poll, and proxy forms must be returned at least 24 hours before the meeting.
