Anton Oilfield Services (03337) saw its shares rise more than 5% in late trading. As of the latest update, the stock was up 5.05% to HK$1.04, with a turnover of HK$18.02 million.

The move follows an announcement from the company. On April 27, 2026, Mr. Luo Lin, the company's founder and Chairman of the Board, along with several senior management members, expressed confidence in the group's future development prospects and recognition of its long-term investment value. They plan to increase their holdings of the company's shares in the open market using their own funds, subject to compliance with applicable laws, regulations, and relevant codes. This share purchase plan is scheduled to take place from the date of the announcement until June 30, 2026, or another period as may be separately announced by the company.

According to the plan, the total investment amount for the intended share purchases by Mr. Luo and the senior management members is not to exceed HK$35 million. Based on a preliminary estimate using the current market price of the company's shares, the total number of shares to be acquired is expected not to exceed approximately 1.0% of the company's total issued share capital. However, the actual number of shares purchased and the investment amount will depend on market conditions, share price movements, regulatory requirements, and trading window arrangements. Consequently, the total number of shares actually acquired and the total investment under the plan may be lower than the stated target.
