Highlights

Q3 2026 production reached 26.3 mmboe, up almost 14% QoQ.
Quarterly sales Revenue rose 49% QoQ to approximately USD 2,006 million.
Free Cash Flow from operations reached approximately USD 1,069 million.
Darwin LNG delivered 98.5% reliability as Barossa achieved steady production.
Full-year production guidance narrowed to 99–102 mmboe.

Santos explores for, develops and produces Natural Gas and oil through operations in Australia and international energy markets. Its portfolio includes LNG Supply chains, Australian gas infrastructure and oil projects in Alaska. In the September 2026 quarter, Santos (ASX:STO) reported higher production and cash generation as Barossa achieved steady output and Pikka contributed new oil volumes. Its latest disclosures also distinguish progress on these projects from continuing operations and conditional transactions within the broader development portfolio.

Record Production and Sales Revenue

Santos (ASX:STO) reported Q3 2026 production of 26.3 million barrels of oil equivalent (mmboe), an increase of almost 14% from the preceding quarter and 23% from Q3 2025. Production for the first nine months reached 71.9 mmboe, almost 10% higher than the corresponding period. The company attributed the quarterly improvement principally to the contribution from Barossa and Pikka alongside its existing operating assets.

Quarterly sales volumes of 26.4 mmboe increased 11% QoQ. Sales revenue was approximately USD 2,006 million, up 49% QoQ and 78% YoY. Revenue changes can differ from production movements because of cargo schedules, prices and sales entitlements. Santos (ASX:STO) reports these measures separately, allowing assessment of operational volumes without treating every produced barrel as an immediately completed sale.

Free cash flow from operations reached approximately USD 1,069 million during Q3 2026, taking the year-to-date amount to approximately USD 1,447 million. Free cash flow was approximately USD 957 million in the quarter and USD 839 million for the nine months.

Barossa Reliability and Pikka Production

Barossa reached steady production during the quarter. Darwin LNG operated at 98.5% reliability, with ten LNG cargoes and two condensate cargoes lifted. Feed gas to Darwin LNG reached a peak of around 600 million standard cubic feet per day.

At Pikka in Alaska, continuous production began in June 2026 and the first oil cargo was lifted in August. Five Pikka cargoes were lifted in Q3, two carrying Santos Equity volumes. The company reported 32 development wells drilled to date and the commencement of seawater injection, which supports reservoir pressure during production.

Pikka briefly reached instantaneous output above 80,000 barrels per day gross. However, operations were temporarily curtailed following weather-related issues affecting seawater treatment and a separate pipeline interruption. Management planned a short period of approximately 70,000 barrels per day to replenish reservoir pressure. Santos (ASX:STO) did not represent the briefly achieved maximum as a sustained rate for the whole quarter.

Guidance and Projects Beyond the Producing Assets

Santos (ASX:STO) narrowed its full-year 2026 production guidance to 99–102 mmboe from 99–105 mmboe. This adjustment followed the operating progress reported during the quarter, but guidance remains contingent on production performance and project timing. Existing operations also contributed, with PNG LNG reliability above 98% and Moomba processing reliability above 99%.

The company executed a binding agreement to increase its participating interest in Papua LNG by 3.3 percentage points to 21% after the PNG State back-in. Completion remained conditional on regulatory approvals and a final Investment decision, planned for Q4 2026. Separately, GLNG joint venture partners entered into agreements to acquire the Greater Meridian coal seam gas project, also subject to approvals.

Santos continued Beetaloo appraisal activity and reported progress at other operating facilities. Potential interruptions, Commodity prices, regulatory decisions, Capital Expenditure and reservoir performance remain relevant operating considerations. Santos (ASX:STO) therefore faces different risks across established production, recently started projects and undeveloped resources.

Key Insights

Santos (ASX:STO) reported a marked increase in production, revenue and free cash flow from operations in Q3 2026. Barossa’s steadier contribution and Pikka’s initial production were important developments, although Pikka also experienced interruptions and reservoir management measures. The revised annual guidance and conditional project agreements describe current activity without establishing future output or cash generation.
