JST Group Corporation Limited reported significant equity movements for the month ended 31 May 2026, highlighted by an aggressive share-repurchase programme that shifted almost 10 million shares into treasury and reduced the company’s outstanding share count.

The issuer bought back 9.89 million shares on the Hong Kong market during May at prices ranging from HKD 14.60 to HKD 16.79. The aggregate consideration is estimated at about HKD 152.41 million. Repurchased shares were retained as treasury stock rather than cancelled.

Following these transactions: • Issued shares (excluding treasury stock) fell 2.27 % from 435.73 million to 425.84 million. • Treasury shares rose from 0.53 million to 10.42 million. • Total issued shares remained unchanged at 436.26 million, matching the level at end-April.

Authorised capital was unchanged at 1.00 billion ordinary shares with a par value of USD 0.0001, representing USD 100,000 of authorised share capital.

Employee share-option activity also decreased the pool of outstanding options. Under the Pre-IPO Share Option Scheme adopted on 8 June 2023, 1.04 million options were exercised in May, leaving 1.46 million options outstanding. No new shares were issued in connection with these exercises; the options were settled using existing shares held by the ESOP trustee.

Despite the sizeable buyback, JST Group confirmed compliance with the Hong Kong Stock Exchange’s prescribed minimum public float of 15 % as of 31 May 2026.
