Key Takeaways

• Santos narrowed full-year 2026 production guidance to 99–105 mmboe, trimming the previous 101–111 mmboe range.

• Second-half output is expected to be roughly 20–30 per cent higher than the first half of 45.6 mmboe.

• Barossa is running at about 97 per cent of planned rates; Pikka in Alaska targets first sales in August 2026.

• Brent crude above US$100 a barrel on 24 July 2026 and firmer LNG prices are tailwinds for cash flow.

• The 2025 XRG/ADNOC-led takeover at US$5.76 (A$8.89) a share collapsed in September 2025 and is not live.

Santos has narrowed its 2026 production guidance after commissioning hiccups delayed a growth surge, yet it expects second-half output up to 30 per cent above the first and a lift from stronger LNG prices. With Brent above US$100 a barrel, the cash-flow story is improving—but execution still carries the risk.

Santos (ASX: STO), one of Australia's largest oil and gas producers, has given investors a mixed message with its second-quarter report: it trimmed its 2026 production forecast after project commissioning ran slower than hoped, while pointing to a much stronger second half and rising liquefied natural gas (LNG) prices that should lift cash flow.

The update, released on 23 July 2026, is a study in timing. The near-term numbers underwhelmed, but the shape of the year—back-end loaded, with two major growth projects ramping up—leaves Santos positioned for a heavier cash-generating period just as energy prices climb. Whether that translates into the "windfall" some investors hope for depends largely on execution.

What Santos changed in its guidance

Santos narrowed its full-year 2026 production guidance to 99–105 million barrels of oil equivalent (mmboe), down from a previous range of 101–111 mmboe. Production is measured in barrels of oil equivalent, a standard unit that converts gas volumes into an oil-equivalent figure so different fuels can be compared.

The trim is modest at both ends of the range, and the company framed it as guidance narrowing "as commissioning uncertainty at its major growth projects eases." In plain terms, the wide range earlier in the year reflected uncertainty over how quickly new projects would come online; with that clearer now, the top end has been pared back. Earlier tropical cyclone disruptions also weighed on output before operations resumed.

First-half 2026 production came in at 45.6 mmboe, with second-quarter output of 23.1 mmboe, up 3 per cent on the first quarter. Second-quarter sales revenue rose 6 per cent quarter-on-quarter to US$1.35 billion (Santos reports in US dollars). First-half free cash flow—the cash left after operating costs and capital spending—was about US$378 million.

The headline for the outlook is the skew to the second half. Santos said second-half production should be roughly 20 to 30 per cent higher than the first half. On the first-half base of 45.6 mmboe, that implies a meaningful step-up in volumes as its growth projects reach fuller rates.

Note on market timing: figures above are drawn from Santos's 23 July 2026 quarterly report and are historical or company estimates. Santos shares eased about 1.5 per cent to around A$7.75 after the update, underperforming a broadly firmer S&P/ASX 200 on the day. The ASX was open when this article was prepared on Friday 24 July 2026.

Who Santos is and where the growth comes from

Santos is a diversified producer spanning domestic gas, oil and LNG. Its portfolio includes the Gladstone LNG (GLNG) and Papua New Guinea (PNG LNG) export projects, the Cooper Basin onshore gas fields, Darwin LNG—now fed by the new Barossa gas field off northern Australia—and the Pikka oil development in Alaska.

Two projects sit at the centre of the 2026 story. Barossa, which supplies gas to the Darwin LNG plant, is now operating at about 97 per cent of planned production rates, with cargoes loading roughly every eight days. First gas has already been achieved, and the field is close to steady-state output.

Pikka, in Alaska, is Santos's other near-term growth engine. Initial wells are delivering around 23,000 barrels a day, with the company targeting a plateau of about 80,000 barrels a day (gross) in the third quarter and first sales expected in August 2026. Beyond 2026, Santos has flagged a final investment decision on Papua LNG targeted for the fourth quarter of 2026 and first gas from its Agogo facility in PNG targeted for the second quarter of 2028.

The through-line is that Santos has spent heavily to build this growth, and 2026 is the year those investments are meant to start paying back in volume—hence the second-half weighting.

The drivers: execution, oil and LNG prices, and geopolitics

Three forces will shape how the year finishes.

The first is project execution. The guidance trim underlines that ramping up large offshore and remote developments rarely runs to a straight line. Commissioning delays, weather and technical issues can all push volumes to the right. The good news for Santos is that the biggest uncertainty—Barossa—now looks largely resolved. The risk is that Pikka's climb to plateau, or the timing of Papua LNG's investment decision, slips.

The second is prices. Santos's second-quarter realised LNG price was about US$11.21 per million British thermal units (mmBtu), a common unit for pricing gas. Many of Santos's LNG contracts are linked to oil benchmarks, often on a lag of several months, so a rise in crude tends to feed through to LNG revenue over time. The company expects higher LNG prices in the third quarter, reflecting the Japan Crude Cocktail benchmark—an oil-linked reference for Asian LNG—having exceeded US$100 a barrel during the second quarter.

The third is geopolitics. Brent crude, the global oil benchmark, traded above US$100 a barrel on 24 July 2026 amid Middle East conflict, its first move past that level since May, according to market reporting. For a producer with meaningful oil exposure and oil-linked gas contracts, higher crude is a direct positive for revenue and cash flow. It is also the least controllable of the drivers: prices lifted by conflict can reverse quickly if tensions ease.

What it means for cash flow, dividends and the balance sheet

The combination of rising second-half volumes and firmer prices is where the cash-flow case is built. More barrels sold into a higher-priced market should, all else equal, lift operating cash flow in the back half of 2026 relative to the first-half free cash flow of about US$378 million.

Stronger cash generation matters on several fronts. It supports Santos's capacity to fund its remaining growth spending—Pikka's ramp-up and the Papua LNG decision—without leaning further on debt. It also feeds the debate over shareholder returns: Santos has in recent years leaned towards returning surplus cash to investors through dividends and buybacks once major projects are delivered. A heavier cash-flow period, if realised, would strengthen the argument for capital returns, though the company has not committed to specific figures in this update and no forecast should be assumed.

The balance-sheet angle cuts both ways. Delays that push volumes into later periods mean the payback on years of capital spending arrives more slowly, keeping gearing—the ratio of debt to equity—higher for longer. Conversely, a clean second-half ramp plus elevated prices would accelerate deleveraging. This is analysis, not a forecast: the outcome hinges on execution and prices that remain outside the company's control.

The takeover backdrop—now history, not a live bid

Any discussion of Santos in 2026 has to address the takeover saga, because it is frequently misremembered as ongoing. In June 2025, a consortium led by XRG—a subsidiary of Abu Dhabi National Oil Company (ADNOC), alongside Abu Dhabi's ADQ and private equity firm Carlyle—made a non-binding, indicative proposal to acquire Santos at US$5.76 (A$8.89) per share, a premium of roughly 28 per cent to the prior close.

That approach did not proceed. The XRG consortium withdrew its proposal in September 2025, with Santos citing an inability to agree acceptable terms on risk allocation, regulatory commitments and domestic gas supply obligations. As of this article's preparation on 24 July 2026, there is no live takeover offer on the table. Investors weighing the stock should treat the 2025 bid as a historical reference point—evidence that a well-resourced buyer once saw value near A$8.89—rather than a current catalyst. Whether another approach emerges is unknown and should not be assumed.

Balancing the opportunities and risks

On the opportunity side: two growth projects are ramping into a rising price environment, the biggest execution risk (Barossa) appears largely behind the company, and higher oil and LNG prices flow relatively directly to cash flow. If the second-half lift lands near the top of the 20–30 per cent range, 2026 could mark the inflection from heavy investment to stronger free cash flow.

On the risk side: the guidance trim is a reminder that ramp-ups can disappoint; commodity prices currently sit at conflict-inflated levels that could unwind; the Papua LNG decision and Pikka plateau remain to be delivered; and the takeover optionality that once underpinned some investors' interest has evaporated.

What investors may watch next

- The next quarterly report, for confirmation that second-half volumes are tracking the guided 20–30 per cent lift. - Pikka's ramp to plateau and first sales in August 2026, plus any update on the Papua LNG final investment decision targeted for the fourth quarter. - Oil and LNG prices, particularly whether Brent holds above US$100 a barrel or retreats as Middle East risk shifts. - Any corporate action, though no offer is currently live following the 2025 XRG withdrawal. - Capital-return signals, including dividend and buyback commentary as cash flow builds.
