ExxonMobil said in its third-quarter reporting that it has agreed to increase its working interest in the Rovuma LNG project in Mozambique to 50%. The company has also raised its stake in Papua LNG in Papua New Guinea to 34% and will take over as operator of the development. It did not disclose the financial terms of either transaction or the identities of the counterparties.

A working interest determines a company's share of the costs and output of a project. The larger holding in Rovuma LNG gives ExxonMobil half of that venture. In Papua New Guinea, the move to operator status places day-to-day management of the development with the company, which gives it greater control over schedules and spending. The announcements indicate a continued focus on liquefied natural gas as a component of the company's international upstream business.

The quarter also brought several cumulative production landmarks. Offshore Guyana, where the company has operated for a relatively short period, output has passed 1 billion barrels. The Kearl oil sands asset in Canada reached the same figure. At PNG LNG, cumulative production of liquefied natural gas has reached 100 million tons.

Production across the company was marginally lower in the period. Total upstream output averaged 4.496 million barrels of oil equivalent per day in the third quarter, compared with 4.514 million in the second quarter. The difference amounts to roughly 18,000 barrels per day, or less than half of one per cent.

Net earnings for the quarter were $15.4 billion. ExxonMobil also set a planned share repurchase target of $20 billion for 2027, which indicates the level of cash return management expects to sustain once current projects are further advanced.

The company attributed upstream earnings across the first nine months of the year to volume growth in Guyana and the Permian Basin. Golden Pass LNG also added volumes. These gains were partly offset by operational impacts in the Middle East, which the company cited without providing further detail in the summary of results.

Earnings from upstream operations fell from the second quarter to the third. ExxonMobil pointed to softer global prices as one cause. The other was an acceleration of entitlement adjustments in Guyana. Under production sharing arrangements, entitlement adjustments alter the portion of output that a producer may claim as costs are recovered, so a faster pace of adjustment reduces the company's share of revenue within a given period. The timing of such adjustments can therefore move earnings between quarters without any change in the volumes pumped.

The result shows how output and earnings can diverge. Production in Guyana has grown through the year and contributed to the nine-month gain in upstream earnings, yet the contractual mechanics there lowered the sequential comparison for the third quarter. Price movements added to that effect.

Alongside its oil and gas reporting, ExxonMobil gave updates on its low-carbon activities. Carbon capture operations have started up at the Nucor facility, and the company said they are now running. The company also secured formal approval for the Rose carbon storage development. The approval allows the project to move into its next stage, though the reporting gave no timetable for construction or first injection.

Taken together, the quarter's disclosures describe a company increasing its exposure to gas projects in East Africa and the Pacific while its largest producing assets continue to grow. The stake increases in Rovuma LNG and Papua LNG will take effect under agreements whose terms remain private. Investors will look to later reporting for details on the cost of the transactions and on how the additional interests affect capital spending in 2027.
