Santos Ltd (ASX:STO) is an Australian oil and gas company with operations in Australia, Papua New Guinea and Alaska. On 19 October 2026, the stock touched a 52-week high and closed the day at $9.32, a gain of 2.31%. In an ASX and media release dated 19 August 2026, Santos reported its half-year results for 2026, with all values in US dollars, covering production, earnings, cash flow, project milestones and its dividend.

Half-year financial results

First-half production was 45.6 million barrels of oil equivalent (mmboe), up 3% on the prior corresponding period. Sales Revenue was $2.6 billion and EBITDAX was $1.6 billion. Net profit after tax was $355 million, with Underlying Profit of $397 million. Free Cash Flow from operations was $378 million, which the company says reflects commissioning at Barossa and Pikka, cargo timing around 30 June and a Papua New Guinea under-lift of about 1.3 mmboe, effects it expects to unwind early in the second half.

The interim dividend is US11.6 cents per share, unfranked, totalling $377 million. Gearing was 23.2% excluding operating leases and 28.1% including them, Liquidity was $3.8 billion, and there are no Debt maturities until September 2027. The release notes a best-on-record personal safety result with no lost-time injuries.

Pikka and Barossa

Pikka in Alaska reached first oil in May, moved to continuous production in June and lifted its first Crude Oil cargo in August 2026. Production is expected to build towards the 80,000 barrel-a-day gross plateau late in the third quarter. At Barossa, seven cargoes were delivered by the end of June and five more since 1 July. Production is around 550 million standard cubic feet a day and is planned to rise to about 600 by the end of the quarter, with a cargo about every eight days at steady state. Darwin LNG delivered 100% plant reliability in the first half.

Outlook and other projects

Santos expects second-half production to be about 20% to 30% higher than the first half. Papua LNG is on track for a final investment decision targeted for the fourth quarter of 2026, with at least 60% targeted to be funded through project financing. The company took a final investment decision on the Moomba Central Optimisation project, targeting more than $600 million of Capital and operating cost savings and a reduction of up to $3 a barrel in Cooper Basin unit costs, supported by a prepayment on a gas sales agreement for 200 petajoules to the South Australian Strategic Gas Reserve from 2030 to 2040. The Moomba carbon capture and storage project has stored about 2.3 million tonnes of CO₂ equivalent since start-up, and the company targets a $2.5 billion net debt reduction by 2030.

Sector backdrop

The S&P/ASX 200 (ASX: XJO) stood at 8,845.70 at 4:25 pm (GMT+11) on 19 October 2026, up 0.44%, or 39.00 points, for the day.

The Santos half-year release is dated 19 August 2026, two months before the 19 October session, so this article does not link the two.

Risks shareholders should weigh

The first-half free cash flow of $378 million was affected by commissioning and cargo timing, and the release relies on those effects reversing in the second half. Barossa is still in commissioning and ramp-up, and Pikka’s plateau rate is an expected figure for later in the third quarter, not an achieved one.

The Papua LNG decision is targeted rather than made, and about 60% project financing is a target. The dividend is unfranked. The release includes a standard statement that actual results may differ from forward-looking statements because of price and currency movements, demand, drilling and production results, regulatory developments and other variables. Gearing, including leases, was 28.1%.

What’s next

The next items in the release are the second-half production increase, Pikka’s build to plateau, Barossa’s step up to about 600 mmscf/d, the Papua LNG final investment decision targeted for the fourth quarter of 2026 and progress on the Moomba Central Optimisation project.
