Key Highlights

  • Production Reaches Record Levels: Santos delivered 26.3 million barrels of oil equivalent (mmboe) in Q3 2026, up nearly 14% QoQ and 23% YoY.
  • Cash Flow Surges: Quarterly free Cash Flow from operations reached approximately USD 1.07 billion, supported by higher production.
  • Guidance Narrows: Santos revised its FY26 production guidance to 99–102 mmboe from 99–105 mmboe amid temporary disruptions at Pikka.
  • Papua LNG Advances: The company progressed plans to increase its Papua LNG interest to 21%, with a final Investment decision targeted for Q4 2026.

Santos Limited (ASX:STO) has delivered its strongest quarterly production and operating free cash flow performance on record, marking a significant milestone in its transition towards higher output from major developments. However, the company's September 2026 quarter also revealed operational challenges at its Pikka project in Alaska, prompting a narrower full-year production forecast.

The contrasting developments place Santos at an important stage, with improving financial performance alongside a major upcoming investment decision for Papua LNG.

Record Production Drives a Sharp Revenue Increase

Santos operates an international portfolio of oil and Natural Gas Assets across Australia, Papua New Guinea, Alaska and Timor-Leste, supplying domestic and export energy markets.

In its third-quarter report released on 22 October 2026, Santos announced record production of 26.3 mmboe, representing growth of almost 14% QoQ and 23% YoY.

Quarterly sales volumes increased 11% QoQ to 26.4 mmboe, while sales revenue climbed to approximately USD 2.01 billion, reflecting increases of 49% QoQ and 78% YoY.

Production for the first nine months of 2026 reached 71.9 mmboe, nearly 10% above the corresponding period in 2025.

The stronger performance reflected increased contributions from the Barossa gas project and the Pikka oil development, alongside reliable operations across the company's established assets.

Cash Flow Strengthens as Major Projects Deliver

The production improvement translated into significantly higher cash generation.

Santos reported record quarterly free cash flow from operations of approximately USD 1.07 billion, bringing its year-to-date total to around USD 1.45 billion.

After relevant investment expenditures, quarterly free cash flow reached approximately USD 957 million, with year-to-date free cash flow at USD 839 million.

At Barossa, gas Supply to Darwin LNG reached a peak of approximately 600 million standard cubic feet per day during the quarter.

Darwin LNG also achieved plant reliability of 98.5%, supporting the shipment of ten LNG cargoes and two condensate cargoes.

Meanwhile, PNG LNG recorded plant reliability above 98%, maintaining an annualised LNG production rate of approximately 8.7 million tonnes.

These results highlight the growing contribution from major developments as Santos moves beyond their initial commissioning phases.

Why Did Santos Narrow Its FY26 Production Guidance?

Despite record quarterly output, Santos reduced the upper end of its FY26 production guidance from 105 mmboe to 102 mmboe, retaining the lower end at 99 mmboe.

The revision followed temporary production interruptions at its Pikka project in Alaska.

Pikka achieved instantaneous production rates exceeding 80,000 barrels of oil per day on a gross basis before the September quarter ended. However, a weather-related disruption affecting the seawater treatment plant and a separate pipeline shutdown interrupted operations.

Consequently, gross production stood at approximately 69,000 barrels per day at quarter-end.

Santos subsequently planned a temporary period of controlled production near 70,000 barrels per day to allow water injection to support reservoir pressure before increasing output.

The revised forecast reflects the operational complexity of ramping up a major oil development, even as the broader portfolio generates higher production and cash flow.

Papua LNG Moves Closer to a Major Investment Decision

Alongside its operating performance, Santos continued advancing its proposed Papua LNG development.

The company entered into a binding agreement to acquire an additional 3.3% participating interest in Papua LNG, potentially increasing its ownership to 21% following the Papua New Guinea government's participation arrangements.

The Acquisition remains conditional on regulatory approvals and the project reaching a final investment decision.

During the September quarter, a revised project agreement established fiscal terms supporting development, while a landholder benefit-sharing agreement was signed in early October.

Operatorship of the Upstream project also transferred to ExxonMobil following the quarter's conclusion.

Santos continues to target a final investment decision in Q4 2026, making the project an important milestone in its longer-term growth plans.

What Could Shape Santos' Next Move?

Santos enters the final quarter of 2026 with record production, stronger cash generation and increased contributions from its major operating assets.

However, execution risks remain relevant, particularly at Pikka, where sustained production depends on reservoir management and operational reliability.

The company also remains exposed to changes in global oil and LNG prices, project development costs and regulatory processes.

Near-term attention will centre on Pikka's production recovery, performance against the revised FY26 guidance and progress towards Papua LNG's final investment decision.

These developments will help determine whether Santos can maintain its stronger operating momentum into 2027.
