Following the transaction, issued shares outstanding (excluding treasury shares) decreased by 0.10 % to 5.72 billion, while the number of treasury shares expanded to 91.26 million. Total issued shares remained unchanged at 5.81 billion.

The buyback forms part of a mandate approved on 12 May 2026 that authorises the company to repurchase up to 596.45 million shares. Including the latest purchase, cumulative repurchases under this mandate stand at 221.36 million shares, representing 3.71 % of the shares outstanding as of the mandate date.

Under Hong Kong listing rules, China Starch is restricted from issuing new shares or transferring treasury shares for 30 days following the buyback, a moratorium that runs through 21 October 2026.

The filing was signed by Company Secretary Leung Siu Hong.
