Seres Group Co., Ltd. (SERES, HKEX: 09927) released its Monthly Return for Equity Issuer covering the period ended 30 September 2026. The filing shows a stable share base with no new share issuances, cancellations or treasury share movements during the month.

Total authorised/registered share capital remained at RMB 1.74 billion, split between 1.63 billion A-shares (par value RMB 1.00 each, Shanghai-listed) and 108.62 million H-shares (par value RMB 1.00 each, Hong Kong-listed).

Issued share capital was unchanged: • A-shares in issue (excluding treasury shares): 1.63 billion • H-shares in issue (excluding treasury shares): 108.62 million • Treasury shares: none in either class

Capital management initiatives: • An H Share Award Scheme approved on 25 June 2026 remains in place with capacity to issue or transfer up to 15.00 million H-shares; no shares were granted or transferred in September. • A previously announced repurchase of 15.68 million A-shares (executed on 22 April 2026) is still pending cancellation; no further repurchases occurred in the current month.

The company confirmed that it met the Hong Kong Stock Exchange’s minimum 5% public-float requirement for its H-shares as at 30 September 2026.

No share option grants, warrant exercises, or convertible security conversions were recorded during the month.

Seres Group’s share capital structure therefore remains unchanged, reflecting a steady equity position as of end-September 2026.
