A $18.7bn Bid for Santos Reopens the Question of Australian Gas Consolidation

A $18.7bn Bid for Santos Reopens the Question of Australian Gas Consolidation Foreign capital is paying a premium for Santos that the local market discounted, and a Woodside tie-up is the obvious domestic answer to an LNG industry that spent $234bn to erode shareholder value. Santos shares surged as much as 15.23% after the Australian oil and gas producer received a non-binding takeover offer of $18.72 billion from an Abu Dhabi National Oil Company-led group, the biggest intraday jump in the stock since April 2020.⁴ That bid has reopened a question the Australian gas sector keeps circling back to: whether its producers should consolidate, and whether the natural counterpart to a foreign bid for Santos is a domestic merger with Woodside. The premium a Gulf bidder is willing to pay says the local market has been undervaluing the assets. It matters because Santos's own numbers show a business the market had marked down. In 2025 its revenue was $4.94 billion, down 8.21% on the prior year, and earnings fell 33.17% to $818 million.³ A producer pushing ahead with its Barossa LNG project and a PNG tie-in, in which it holds a 39.9% stake in PNG LNG, is carrying growth assets that a $18.7 billion suitor evidently values more highly than the ASX did before the bid.^5,3 Foreign capital is arbitraging the gap between asset value and share price. The deeper backdrop is an industry that over-invested for thin returns, which is the real case for consolidation. Australia's LNG growth wave deployed an immense $234 billion in capital expenditure, more than twice the current market capitalisation of Australia's 20 largest fossil fuel companies.¹ Yet by one analysis that growth wave eroded $19 billion of shareholder value, with the projects achieving internal rates of return of between 3.4% and 10.4%, and only Chevron's Gorgon exceeding 10%.¹ Across all Australian LNG facilities, the industry eroded $1.8 billion of shareholder value.¹ An industry that spent a fortune to build capacity and destroyed value doing it is precisely the kind that consolidates to wring out returns. That is what makes a Woodside-Santos combination more than idle speculation. Merging Australia's two largest gas producers would create a national LNG champion with the scale to cut duplicated cost, rationalise capital programmes and compete for the long-term Asian contracts that underpin the business. The logic is the same logic driving the global wave of upstream consolidation: when organic growth has delivered poor returns, buying scale and squeezing synergies is the path to better ones. The demand case for the assets remains intact, which is why bidders are circling. Some forecasters estimate Australian LNG production over the next decade will pass Qatar's and reach up to 100 million tonnes a year, and the Iran-war disruption to Middle East supply has only sharpened Asia's appetite for reliable, non-Gulf gas.² A consolidated Australian producer would be positioned to supply that demand from a single, larger platform, which is part of what a foreign bidder is paying for in Santos. The tension is between foreign acquisition and domestic combination. The ADNOC-led bid would put a strategically important Australian gas producer under Gulf ownership, which raises the political question of whether a domestic merger with Woodside is the preferred outcome.⁴ A Woodside-Santos tie-up would keep the assets Australian and create national scale, but it would also concentrate the country's gas industry in a way regulators would scrutinise. The choice is between selling to the Gulf at a premium and building a domestic champion. The signal to watch is whether the Santos board engages the ADNOC bid or a counter-proposal emerges, because that determines which model of consolidation wins.⁴ If the foreign bid proceeds, Australian gas passes into Gulf hands at a valuation the local market would not pay. If a Woodside combination materialises as the alternative, the industry consolidates domestically to fix the returns that $234 billion of capex failed to deliver. Either way, the era of Australian gas producers competing separately on poor margins is being challenged, and the $18.7 billion bid is the opening move.^4,1
