RemeGen Co., Ltd. (RemeGen) has filed its Monthly Return for Equity Issuer for the period ended 30 September 2026 with Hong Kong Exchanges and Clearing Limited, confirming minimal changes to its share capital and continued compliance with public-float requirements.

Authorised / Registered Capital • RemeGen’s aggregate registered share capital remained unchanged at RMB 564.48 million, split between 208.58 million H shares and 355.90 million A shares, each with a par value of RMB 1.

Issued Shares • H shares (HKEX: 09995) were stable at 208.58 million with no treasury shares outstanding. The company affirmed compliance with the Hong Kong Stock Exchange’s minimum 5% public-float threshold for PRC issuers. • A shares (SSE: 688331) declined marginally by 19,000 to 355.64 million following a repurchase executed on 11 September 2026. Treasury A shares increased by the same amount to 254,184, leaving total A shares unchanged at 355.90 million.

Share Repurchase Activity • On 11 September 2026, RemeGen repurchased 19,000 A shares at RMB 113.434 per share, spending approximately RMB 2.16 million. The repurchased shares were earmarked for the company’s employee equity incentive programmes.

Equity Incentive Schemes • Under the 2022 and 2023 A-Share Incentive Schemes, a cumulative 2.13 million restricted A shares remain available for future issuance or transfer from treasury: – 2022 Scheme (First Grant): 0.69 million shares outstanding – 2022 Scheme (Reserved Grant): 0.36 million shares outstanding – 2023 Scheme (First Grant): 1.08 million shares outstanding No new shares were issued, and no treasury shares were transferred during September under these plans.

Capital Structure Outlook With no new H-share issuance and only a negligible 0.01% reduction in outstanding A shares, RemeGen’s share base remains effectively steady. The limited buyback aligns with the company’s strategy to support its equity incentive plans without materially diluting existing shareholders. All other capital instruments—options, warrants and convertibles—reported no activity during the month.
