CNOOC increases stake in China Oilfield Services, still below target

China National Offshore Oil Corporation (CNOOC), the controlling shareholder of China Oilfield Services Limited, has increased its stake in the company by 16,008,000 H shares. This transaction on the Stock Exchange of Hong Kong Limited between April 9, 2025, and October 8, 2025, represents approximately 0.34% of the total issued shares. The accumulated investment for this increase amounts to approximately RMB80.9817 million.

Following this acquisition, CNOOC now holds a total of 2,426,857,300 shares, representing approximately 50.86% of China Oilfield Services' total issued shares. Despite this increase, the actual shareholding increase has not yet reached 50% of the lower limit of the planned amount, primarily due to fluctuations in share prices and broader capital market trends.

CNOOC intends to continue increasing its shareholding in China Oilfield Services as appropriate, utilizing its self-owned funds, in accordance with the Shareholding Increase Plan. The company also noted potential risks that the plan might not meet expectations due to market changes or other unpredictable factors.
