Santos Takeover Bid Puts a Price on Australian LNG as Export Tax Pressure Mounts
An $18.72bn Abu Dhabi offer for Santos tests foreign appetite for Australian gas assets as Canberra debates a 25% export levy.
Shares in Santos surged as much as 15.23% on Monday (2026-05-18) after the company received a non-binding takeover offer of $18.72 billion from an Abu Dhabi National Oil Company-led group, LSEG data show. The cash bid of $5.76 ($8.89 Australian) per share carries a 27.73% premium to Santos's closing price of AU$6.96 last Friday (2026-05-15).2
The bid arrives as Australia's LNG exporters are pocketing windfall profits from the Middle East conflict while facing a mounting political backlash at home. A Bloomberg report from early July (2026-07-05) put the sales bonanza at A$20 billion ($14 billion), driven by the loss of Qatari supply to the war. That good fortune has triggered public criticism, with momentum building in Canberra for an export tax that would force producers to prioritise domestic supply.8,6
The market context is unforgiving. Supply disruptions have already tightened the global balance, and Woodside's quarterly report points to operational strain alongside commercial gains. Woodside confirmed there have been no disruptions to its trading activities as a result of the Middle East conflict, with shipping continuing as planned, while also noting strong spot LNG demand. A tropical cyclone in western Australia separately halted production at the country's largest export sites, according to Montel, exacerbating the tightness caused by the loss of Qatari barrels.4,1
That cyclone-driven outage, reported in May (2026-05-21), hit plants run by Chevron and Woodside and strained global supply at a delicate moment. Australia is the world's second-largest LNG exporter, and any sustained downtime in its northwest basins removes cargoes from a market already pricing in elevated risk.5
Woodside's own operational metrics show resilience where it counts. The Sangomar FPSO continues to demonstrate high reliability and the reservoir is performing better than expected, while the Shenzi field in the US achieved reliability of 99.0% after completing production optimisation initiatives including flowline pressure reduction. The Beaumont New Ammonia facility assumed operational control in March 2026 following performance testing and a $470 million final payment to OCI Global, with the first ammonia cargo shipped in February.4
The numbers suggest a company working to sustain volumes while geopolitics does the lifting on price. A project expected to contribute approximately 20 Mbbl/d of gross peak annualised oil production, around 5 Mbbl/d on a Woodside share basis, is slated to add to the output picture.4
The corporate activity around Santos sharpens the debate over who captures Australian gas wealth. The Abu Dhabi group's bid comes from XRG, an investment firm with an enterprise value of over $80 billion that has been pursuing deals in natural gas, chemicals and lower-carbon energy solutions. XRG's move is part of a consolidation wave that began with preliminary merger talks between Woodside and Santos in December 2023.2,3
That consolidation impulse collides with a domestic policy environment turning hostile to export revenues. Tax momentum is building around a proposal that would impose a 25% export levy, a mechanism that would redirect supply to local consumers by making domestic sales more lucrative than exports. Supporters argue such a tax would override the need for forced domestic reservation.6
Woodside has also expanded its Australian footprint by assuming operatorship of the Gippsland Basin Joint Venture and Kipper Unit Joint Venture from ExxonMobil, with both partners retaining 50% stakes. The transfer adds mature, reliable gas supply to Woodside's portfolio at a time when the company is balancing growth projects against a choppy demand environment.7
A foreign buyer paying a near-28% premium for Santos signals that global investors see durable value in Australian reserves even as Canberra weighs a tax that would cut into future export margins. Santos's board has not yet responded publicly to the Abu Dhabi offer. How it does so, and how far the export tax proposal advances through the legislative calendar, will shape the terms under which Australian gas wealth changes hands.2,6
