UK North Sea dealmaking tops $19.6bn as taxes and oil prices drive consolidation

Oil and gas mergers and acquisitions involving a UK target or buyer have reached US$19.6 billion so far this year, overtaking the US$16.5 billion recorded for the whole of 2025, according to LSEG data reported by Free Malaysia Today. That makes 2026 the strongest year for such activity since at least 2022, when Russia's full-scale invasion of Ukraine triggered the previous energy crisis.

Eleven industry analysts and bankers told Reuters — in reporting carried by Free Malaysia Today — that tax advantages and high energy prices will drive further consolidation in the ageing North Sea basin.

The cash is there. Oil and gas prices have climbed to multiyear highs on disruption linked to the US-Israeli war with Iran, swelling the coffers of an industry that has been reporting results this week. But the same price surge has fed inflation across the economy, sharpening the case for scale to justify production in a mature basin that the British government treats as a secure domestic supply source.

Tax rate sharpens the logic

The UK's fiscal regime is doing much of the work. An Energy Profits Levy introduced by the previous Conservative government and increased under the current Labour government has lifted the headline tax rate on UK upstream oil and gas activity to 78%.

"There's been a lot of tax-driven consolidation in recent years," Greig Aitken, director of corporate research at Wood Mackenzie, was quoted as saying.

Tony White of advisory firm MKI pointed to the same arithmetic: "There's still a rationale for two UK North Sea players to combine, so that the enlarged company can take advantage of the tax credits as well as operational synergies."

The buyer pool, though, is thin. James McCormack of investment bank and research firm Cavendish described the North Sea as "an increasingly concentrated market when it comes to credible buyers with the balance sheet, tax capacity and decommissioning capability to execute material deals." A Cavendish report published in September argued that companies offering diversification, liquidity and development capital are attracting premium valuations, while sub-scale operators face growing pressure to merge, raise capital in deeper markets or accept takeover approaches.

Alexander Franke, an energy consultant at Oliver Wyman, expects cost containment to drive more activity, with the caveat that the pace depends on the oil price outlook — an unexpected fall could deter buyers, while sustained gains would boost cash flow and funding for acquisitions.

Policy cuts both ways

Government uncertainty complicates the picture. Britain has said it remains committed to net-zero greenhouse gas emissions by 2050, yet it approved development of the Jackdaw North Sea gas field earlier this month after years of debate between environmental campaigners and supporters who cited jobs and a domestic gas source. In its autumn budget statement on Wednesday, the government reiterated its long-term commitment to keeping oil and gas in the energy mix but announced no new measures for the sector.

The majors have been exiting regardless. Shell has chosen to manage its remaining North Sea exposure through partnerships and joint ventures, including the creation of Adura with Norway's Equinor. BP, the last major with a significant North Sea focus, said in July it plans to sell its oil and gas fields in the basin as part of a portfolio overhaul, a sale analysts have estimated could raise US$2 billion and set off another consolidation wave.

"Most likely the buyer is another North Sea consolidator. Value will be driven by infrastructure and tax synergies rather than by reserves alone," Cavendish's McCormack said, naming UK companies EnQuest, NEO NEXT+ and Ithaca as possible bidders. The next round of bidding will be in December, according to one person with knowledge of the process. BP declined to comment further. EnQuest chief executive Amjad Bseisu has said he is interested in the assets, and the company offered no further comment; Ithaca declined to comment and NEO NEXT+ did not respond to a request for comment.

A wider cycle

The trend extends beyond the North Sea incumbents. London-listed Genel Energy in September raised its offer for Britain's Capricorn Energy to US$436 million, outbidding Norway's DNO. Israel's Ratio Petroleum outbid Serica Energy in August with a sweetened US$196 million offer for Pharos Energy; Serica said it continues to evaluate acquisition opportunities in the UK North Sea and internationally.

This month, Gulf Keystone Petroleum and ShaMaran Petroleum announced a US$601 million all-share merger, while Ithaca agreed to buy three offshore oil assets from Canada's Suncor for C$1.2 billion (US$853.49 million).

The common thread, according to the analysts and bankers, is that rising costs, policy uncertainty and the push for efficiency leave smaller operators with few options beyond combining or selling.
