What were the two largest upstream oil and gas M&A deals in the US during Q1 2026, and what were their key strategic implications?

The two largest upstream oil and gas M&A deals in the US during Q1 2026 were: (1) Devon Energy’s all-stock merger with Coterra Energy for $25 billion, creating a company with an estimated $58 billion market value, dominant positioning in the Delaware Basin, and combined daily production of over 1.6 million barrels of oil equivalent; and (2) Mitsubishi Corporation’s $7.5 billion acquisition of Ensign Energy’s U.S. shale gas and pipeline assets — comprising $5.2 billion in equity and $2.33 billion in assumed net debt — covering ~380,000 acres in the Haynesville Shale, 1,700+ miles of dedicated pipeline, current gas production of 2.1 Bcf/d (equivalent to ~15 million tons/year of LNG), and projected output growth to 2.6 Bcf/d by 2027–2028, directly supporting Mitsubishi’s Cameron LNG project on the Gulf Coast.

Why is the US upstream oil and gas M&A market heating up in early 2026, according to Enverus?

According to Enverus, the US upstream oil and gas M&A market is heating up in early 2026 due to sustained high oil prices, which are boosting both the willingness of private operators to pursue public listings or sales and the acquisition appetite of publicly traded exploration and production companies — collectively triggering a new wave of industry consolidation, although March activity slowed temporarily amid heightened market volatility from escalating Middle East geopolitical tensions.
