3SBio Inc. has issued a circular convening its annual general meeting (AGM) for 25 June 2026 in Shenyang, where shareholders will vote on a series of key resolutions.

General & Repurchase Mandates • A fresh general mandate authorising directors to issue, allot or transfer up to 20% of issued shares—equivalent to a maximum 507.62 million new or treasury shares, based on 2.54 billion shares outstanding as at 27 May 2026—will be put to shareholders. • A separate mandate would allow on-market buy-backs of up to 10% of issued shares (253.81 million shares). Shares repurchased could be cancelled or held as treasury stock.

Final Dividend Proposal • The board proposes a final dividend of HK$0.25 per share for FY 2025, to be funded from the share premium account. • The payout totals roughly HK$634.50 million and would leave RMB5.21 billion in the premium reserve (RMB5.76 billion before distribution). • Subject to approval, the dividend will be paid in cash on 4 August 2026 to shareholders on record at close of business 27 July 2026. Share transfer registration will be suspended 23–27 July 2026.

Board Changes • Independent non-executive directors Mr Pu Tianruo and Mr Ng Joo Yeow Gerry will retire by rotation and stand for re-election.

Auditor Replacement • Ernst & Young will retire at the AGM. The board, on audit-committee recommendation, nominates KPMG as new external auditor for the year ending 31 December 2026, with an estimated audit fee of RMB5.00–5.50 million. No disagreements or matters requiring shareholder attention were reported.

AGM Logistics • Shareholders’ register will be closed 22–25 June 2026 for AGM eligibility; record date is 25 June 2026. All resolutions will be decided by poll, and treasury-share holders will abstain from voting.
