Energy M&A Outlook for 2026

Introduction

Energy M&A in 2026 has not followed the script. The EIA's January 2026 outlook had Brent averaging about $56 for 2026. Instead, the US-Israel-Iran war that began on February 28 largely closed the Strait of Hormuz, and Brent passed $100 in mid-March, then returned above it by October after a summer lull (the Strait of Hormuz crisis covers the event). The result is a two-speed deal market: upstream swung from a two-year high to one of its weakest quarters since 2020, while power and infrastructure became the year's most active theme. The deal-by-deal reference is Landmark Energy Deals of 2026.

The year opened with Devon/Coterra, an all-stock merger announced on February 2 and closed on May 7, with a combined enterprise value of about $58 billion (Enverus values the Coterra acquisition itself at about $25 billion). It is a defensive mid-cap combination in the Permian endgame mould. Gas drew foreign strategic capital too: Mitsubishi agreed in January to buy Haynesville producer Aethon for about $7.5 billion including debt, a bet on LNG-linked gas demand. First-quarter US upstream M&A reached $38 billion, a two-year high, by Enverus's count.

Bid-Ask Spread in Energy M&A

The gap between what a seller will accept and what a buyer will pay for an oil and gas asset, driven mostly by the price deck each side uses. Sellers anchor on spot prices and recent cash flow; buyers underwrite the futures strip. When spot and strip diverge sharply, as after a supply shock, the spread widens and deals stall.

Then the war reached the deal tape. Second-quarter upstream M&A fell to $9.1 billion, down 76% from the first quarter, according to Enverus data reported by World Oil. More than 40% came from one federal lease sale in New Mexico, though public operators kept buying, including Matador's $1.3 billion purchase of Paloma Permian. Enverus called it "a temporary negotiation obstacle rather than a demand problem" and expects higher oil prices to lift buyers' cash flow and bring more private sellers into A&D processes in the second half.

AI data center demand kept dispatchable generation scarce, and buyers paid for existing plants rather than wait years to build. Vistra agreed in January to buy Cogentrix (10 gas plants, about 5.5 GW) from funds managed by Quantum Capital Group for a net $4.0 billion, and Talen closed its $3.45 billion purchase of 2.6 GW of PJM gas plants from Energy Capital Partners in June. Both are sponsor exits to strategics, the route private gas fleets have taken since the Constellation/Calpine supercycle repriced them.

The two largest deals were about funding the build. NextEra Energy agreed in May to combine with Dominion Energy in an all-stock deal worth about $67 billion of equity, creating the world's largest regulated electric utility business. In March, a consortium led by Global Infrastructure Partners and EQT agreed to take AES private at $15 a share, an enterprise value of about $33.4 billion funded entirely with equity, as POWER magazine reported. Funding 8.2 GW of signed data center contracts as a listed company would likely have meant cutting AES's dividend or issuing heavy amounts of stock; infrastructure capital removed that trade-off (see the energy PE landscape).

Remedies: Constellation's Divestitures to LS Power

Power deals now also create a second round of M&A through antitrust remedies. To close Calpine in January, Constellation accepted DOJ and FERC divestiture conditions, then agreed in March to sell five PJM plants (about 4.4 GW in Delaware and Pennsylvania) to LS Power for $5.0 billion (expected to close by year-end). LS Power also agreed to buy the 606 MW Brazos Valley plant in ERCOT for $860 million, a sale Constellation completed on October 14. Having sold 13 GW to NRG in January, LS Power is back as a buyer: divestiture packages are a rare way to buy large blocks of capacity in tight markets.

Midstream M&A slowed into 2026, with buyers favoring bolt-on acquisitions such as Western Midstream's roughly $1.6 billion purchase of Delaware Basin gatherer Brazos Delaware II at about 8.0x 2027 EBITDA. The bigger story is LNG contracting. With Qatar's Ras Laffan complex damaged and QatarEnergy under force majeure, buyers are seeking long-term US supply, and Venture Global sanctioned CP2 Phase 2 in March with an $8.6 billion project financing. That is project finance and offtake work more than M&A; SPA mechanics explain why a signed SPA makes a terminal financeable.

OFS consolidation completed its technology pivot when Baker Hughes closed its $13.6 billion acquisition of Chart Industries on July 16, a year after SLB absorbed ChampionX. The next OFS deals will likely chase the same recurring, non-drilling revenue in LNG, power and digital markets. Internationally, the war made security of supply a deal thesis, with Japanese capital moving into US gas to reduce reliance on the Gulf.
