CHINA OIL & GAS (China Oil And Gas Group Limited) filed its monthly return for the period ended 31 May 2026, indicating stable share capital and full compliance with Hong Kong’s public-float requirements.

The company’s authorised share capital remained at 125.00 billion ordinary shares with a par value of HKD 0.01, equivalent to HKD 1.25 billion. No adjustments were recorded during the month.

Issued share capital was unchanged at 5.64 billion ordinary shares, and the group continued to hold zero treasury shares. Management confirmed that more than the minimum 25 % public-float threshold was maintained at month-end.

Under the New Share Option Scheme and New Share Award Scheme (both approved on 15 June 2023), up to 0.56 billion new shares may still be granted, but no options, awards or share issuances were outstanding or exercised in May.

The filing shows no activity in warrants, convertible instruments, share repurchases or other share-related arrangements during the month.

The return was submitted by Chairman Xu Tie-liang on 1 June 2026.
