Anton Oilfield Services Group announced that it repurchased 6.30 million ordinary shares on 29 May 2026 via on-market transactions at prices between HK$0.92 and HK$0.96 per share, for a total consideration of HK$5.95 million.

As of the same date, the company’s issued share capital remains unchanged at 3.00 billion shares, with no treasury shares on hand. The newly repurchased shares, along with earlier buybacks conducted on 5 December 2025, 18 December 2025, 12 January 2026 and 11 May 2026, bring the cumulative number of shares bought for cancellation but not yet cancelled to 42.93 million, representing approximately 1.46 % of the existing issued share base.

The latest repurchase utilised the general mandate approved by shareholders on 27 May 2026, which authorises the company to buy back up to 300.17 million shares (about 10 % of issued shares). To date, 6.30 million shares, or 0.21 % of the mandate limit, have been executed under this authority.

In line with Hong Kong Stock Exchange rules, Anton Oilfield is subject to a moratorium on issuing new shares or disposing of treasury shares until 28 June 2026.
