China Medical System Holdings Limited (CMS) reported a small adjustment to its capital structure for the month ended 31 May 2026, driven solely by a share repurchase transaction carried out on 29 May 2026.

Key figures:

• Authorised share capital remained unchanged at 20.00 billion ordinary shares with a par value of USD 0.005, translating to total authorised capital of USD 100.00 million.

• Issued shares (excluding treasury shares) fell by 1.02 million to 2,438.51 million, a 0.04% reduction from the previous month.

• Treasury shares increased by the same 1.02 million, bringing total issued shares (including treasury shares) back to 2,439.53 million.

• The repurchase price averaged HKD 10.59 per share, implying an outlay of approximately HKD 10.80 million.

• CMS confirmed compliance with the Main Board’s minimum 25% public-float requirement as at 31 May 2026.

No new share options, warrants, convertibles or other equity-linked instruments were issued during the period. The May activity was limited to the single board-approved buy-back, which received shareholder authorisation on 23 April 2026.

With the latest repurchase, CMS continues to manage its capital base while keeping the overall share count largely stable and maintaining regulatory float thresholds.
