CNOOC Limited stock gains 2.14 percent on stake increase

CNOOC Limited (ISIN HK0883013259) stood at HKD 23.84 on the Hong Kong Stock Exchange on September 24, 2026, up 2.14 percent from HKD 23.34. The move followed an announcement that CNOOC raised its stake in an oilfield services unit to 50.91 percent, as MarketScreener reported on September 24, 2026.

H1 profit reaches RMB 85.8 billion

The latest operating backdrop is also favorable. In the first half of 2026, net profit attributable to shareholders rose 23.4 percent year over year to RMB 85.8 billion from RMB 69.5 billion, according to Reuters on August 26, 2026. Oil and gas sales revenue increased 20 percent to RMB 206.1 billion.

Production supported the earnings result, reaching a record 398.7 million barrels of oil equivalent in H1 2026, up 3.7 percent year over year. The company maintained its 2026 production target of 780 million to 800 million barrels of oil equivalent and capital expenditure guidance of RMB 112 billion to RMB 122 billion, Reuters reported.

Dividend adds a second shareholder signal

CNOOC also declared an interim dividend of HKD 0.94 per share for H1 2026, a record since its listing, according to PR Newswire on August 26, 2026. The payout ratio was 45.2 percent, while all-in cost stood at USD 29.70 per barrel of oil equivalent.

For investors, the combination of a 23.4 percent profit increase and 3.7 percent production growth shows that earnings expanded faster than output during the period. That spread places oil prices, realized prices and capital discipline alongside production as the key variables for the next update.
