Key Highlights

• Santos said third-quarter production was up about 14 per cent on the June quarter and 23 per cent on the same quarter of 2025.

• Sales Revenue was US$2,006 million, compared with US$1.13 billion a year earlier, and free Cash Flow from operations was about US$1.07 billion, which the company described as a record.

• That is consistent with first-half production of 45.6 mmboe reported in August.

• Santos reported that Barossa, the offshore gas project supplying Darwin LNG, reached steady-state production, with Darwin LNG running at 98.5 per cent reliability in the quarter.

How did Santos post a record quarter while trimming its full-year outlook? The answer is that new projects finally began contributing at scale, even as a slower ramp-up at its Alaskan oil development narrowed the top end of 2026 production guidance. In its third-quarter report on 22 October 2026, Santos (ASX:STO) reported production of 26.3 million barrels of oil equivalent (mmboe), a quarterly record.

Why the third quarter matters

Santos said third-quarter production was up about 14 per cent on the June quarter and 23 per cent on the same quarter of 2025. Sales revenue was US$2,006 million, compared with US$1.13 billion a year earlier, and free cash flow from operations was about US$1.07 billion, which the company described as a record.

The significance lies in timing. Investors have watched Santos spend heavily on Barossa gas and Pikka oil, and the third quarter is the first period in which both are producing in earnest.

That is consistent with first-half production of 45.6 mmboe reported in August.

What Santos does

Santos is an Adelaide-headquartered oil and gas producer. Its Earnings come from liquefied Natural Gas (LNG) exported from Queensland, Papua New Guinea and, increasingly, Darwin; pipeline gas sold into Australian domestic markets; and Crude Oil and condensate, including a growing contribution from Alaska's North Slope.

Revenue therefore depends on volumes and on prices. Many LNG contracts are linked to oil, while domestic gas is generally sold under negotiated contracts. This gives the company exposure to both global energy benchmarks and local Supply conditions.

Barossa and Pikka: the growth engines

Santos reported that Barossa, the offshore gas project supplying Darwin LNG, reached steady-state production, with Darwin LNG running at 98.5 per cent reliability in the quarter. In August the company had said Barossa was producing about 550 million standard cubic feet a day and targeted around 600 by the end of the third quarter.

Pikka Phase 1 in Alaska lifted its first oil cargo in August 2026. Ramp-up has been uneven, however. Reports that delays commissioning a seawater treatment plant, curtailments after a weather event and a pipeline shutdown following a road accident all weighed on the outlook. Management had targeted a gross plateau of 80,000 barrels a day in late third quarter, a milestone the narrowed guidance suggests will arrive later.

The guidance change

Santos narrowed 2026 production guidance to 99 to 102 mmboe, from 99 to 105 mmboe, and sales volumes to 102 to 105 mmboe, from 102 to 108 mmboe. The lower bound is unchanged, so this is a trim of the upside rather than a downgrade of the core range.

What the first-half results showed

The record quarter followed a weaker first half. For the six months to 30 June 2026, Santos reported product sales revenue of US$2,620 million, up 2 per cent, but Underlying Profit of US$397 million, down 22 per cent, and statutory net profit of US$355 million, down 19 per cent.

Operating free cash flow fell 65 per cent to US$378 million. Santos pointed to lower realised LNG prices, higher depletion, commissioning costs at Barossa and Darwin LNG, higher purchase costs and a change in Depreciation methodology from proven and Probable Reserves to proven reserves.

An Interim Dividend of 11.6 US cents per share, unfranked, was declared, 13 per cent lower than a year earlier. Gearing was reported at 23.2 per cent excluding operating leases, with no Debt maturities until September 2027.

Against that backdrop, the third-quarter cash flow figure matters. The company had said first-half pressures from commissioning, cargo timing and a Papua New Guinea under-lift were expected to unwind in the second half, and the quarter is consistent with that, though a single quarter is not a trend.

Papua LNG and other developments

Santos is acquiring an additional 3.3 per cent interest in Papua LNG, which would lift its stake to 21 per cent after the State back-in, subject to regulatory approvals. A final Investment decision is planned for the fourth quarter of 2026, with at least 60 per cent of funding targeted from project financing, according to the August results.

The company also reported long-term LNG supply arrangements with POSCO Steel and Western LNG, completion of the sale of its Mahalo joint venture stake, and progress at its Moomba carbon capture and storage facility, which has stored more than 2.5 million tonnes of carbon dioxide equivalent. A final investment decision has also been taken on Moomba Central Optimisation, aimed at lowering Cooper Basin unit costs.

Sector conditions and competitive position

Santos competes with other Australian LNG exporters and with international producers for Asian buyers. Its scale, diversified asset base across Australia, Papua New Guinea and Alaska, and portfolio of long-term contracts are strengths. Its disadvantages include the Capital intensity of large developments and the exposure of earnings to Commodity prices it cannot control.

Domestic gas policy is also relevant. Santos has secured a prepayment supporting supply of 200 petajoules of gas to South Australia's Strategic Gas Reserve from 2030 to 2040, illustrating how government priorities increasingly shape project economics.

Risks and what to watch

Several uncertainties remain. Pikka's ramp-up has already been disrupted by weather, equipment commissioning and logistics, and further delays are possible. Papua LNG is a large project in a complex jurisdiction, and a final investment decision is not guaranteed.

Energy prices are volatile, and lower realised LNG prices already weighed on first-half earnings. Regulatory approvals and emissions expectations may also affect returns.

Upcoming events include the Papua LNG decision targeted for the fourth quarter, further evidence of Pikka reaching plateau, and the full-year 2026 results, which should show whether the improved cash generation seen in the third quarter holds across the second half.
