U.S. upstream M&A hits $12.6 billion in 3Q26, October tacks on another $18 billion

CALGARY, Alberta (Nov. 5, 2026) - Enverus Intelligence® Research (EIR), a subsidiary of Enverus, the leading energy data analytics platform, has released its summary of recent U.S. upstream M&A activity and market outlook, highlighting a steady third quarter led by private equity exits followed by companies hitting big deals in October including the return of public E&P consolidation and public-to-public asset sales.

U.S. upstream deal value reached $12.6 billion in 3Q26, up modestly from $11.5 billion in the second quarter, with multiple established market trends contributing to activity. Public companies Matador Resources and Magnolia Oil & Gas added inventory, international buyers secured gas exposure and asset-backed securitization (ABS) groups targeted mature production. Activity accelerated in October with two large public-to-public transactions: EQT's $13.8 billion all-stock acquisition of Range Resources and Crescent Energy's $4.2 billion purchase of Devon Energy's Eagle Ford asset. Including those deals, 2026's value stands at $80.5 billion, already comfortably ahead of 2025's full-year total.

"Sustained higher oil prices and steady international demand for U.S. gas keep pushing asset prices higher. Competitive bidding means buyers can no longer win deals by paying only for well-delineated inventory. They are underwriting value beyond the base case, whether that is emerging intervals in the Permian or redevelopment potential in the Eagle Ford," said Andrew Dittmar, principal analyst at EIR.

Private-to-public transactions accounted for two-thirds of 3Q26 disclosed value, driven by private equity's push to exit while oil prices are elevated and continued inventory demand from public buyers. WildFire Energy captured the quarter's top deal in its sale to Magnolia Oil & Gas in the Eagle Ford while Birch Permian and Paloma Permian sold in the Midland and Delaware basins, respectively. The Permian remained the most consistent engine of activity, contributing about a third of announced 3Q26 value, a share that understates activity given Midland driller FireBird Energy's undisclosed price in its sale to Continental Resources. Less delineated zones are increasingly part of the investment case as buyers chase opportunities to grow inventory. The Permian has remained the undisputed king among U.S. shale plays for unlocking new productive zones.

Higher oil prices also lifted the Eagle Ford, which is on pace for its largest annual deal value total since 2018. It also holds resource expansion stories that are increasing buyer interest, including redevelopment opportunities or revisiting acreage that was developed much earlier in the shale cycle. To take advantage of this opportunity, E&Ps either choose to recomplete older wells or drill new wells nearby with modern designs. The core of the Eagle Ford has been the most successful area for this strategy, and the opportunity to recover more oil from previously developed acreage is likely part of the draw for Crescent Energy in acquiring Devon's Eagle Ford assets in its 4Q26 acquisition.

"The industry is continuing to innovate as inventory dwindles and E&Ps are finding opportunities to unlock additional oil resource," added Dittmar. "Naturally, these strategies are also being considered when evaluating deals and are increasingly becoming part of the value proposition for buyers."

Weak Henry Hub pricing failed to cool gas M&A, and especially interest from international buyers. Azerbaijan's state oil company SOCAR's purchase of a stake in Comstock Resources' assets was yet another example of an international buyer securing Haynesville exposure. International groups have come to dominate Haynesville M&A, with their appetite for U.S. gas pushing up asset pricing and crowding out domestic buyers. The Haynesville is the focal point for international firms because of its proximity to the growing LNG corridor along the U.S. Gulf Coast. However, the high price for inventory and a lack of remaining targets will push groups to cast a wider net and consider other plays. There was evidence of that in 3Q26 with POSCO International, the subsidiary of a South Korea-based POSCO, initiating its foray into U.S. upstream asset ownership by acquiring Chord Energy's non-operated Marcellus assets in Pennsylvania. When looking at assets further away from the Gulf Coast, pipeline capacity and transportation commitments will be key considerations to avoid weak localized pricing relative to Henry Hub-linked LNG commitments.

International buyers aren't the only ones expanding gas exposure. EQT's October acquisition of Range marks a return to corporate consolidation with the first tie-up of large public gas producers since Chesapeake Energy and Southwestern Energy merged in early 2024. The deal creates the largest U.S. gas producer at more than 9 Bcfe/d, adds Range's liquids-rich production and has clear operational synergies, including integration with EQT's midstream system.

"Gas producers generally have deep inventory compared to oil-focused peers and EQT was already a leader in the group. While inventory and resource expansion played a role in the deal, including an emerging Deep Utica interval, we see the acquisition as largely about scale, synergies and maintaining a very low cost of gas supply. The scope of EQT's production and its integrated midstream infrastructure help it become the counterparty of choice for in-basin demand while maintaining about 15% LNG exposure. Weak gas pricing in 2026 did not deter EQT or international buyers, which reflects confidence in long-term U.S. gas demand growth, including locally in Appalachia," said Dittmar.

Moving forward, deal markets are likely to maintain momentum as high oil prices linger. The Permian still has a few targets and the combination of high oil and enthusiasm for new intervals will draw buyers toward acquisitions. The Williston Basin, which hasn't seen much activity in 2026, could catch up and see a boost in activity like the Eagle Ford as private sellers take advantage of a good window to sell. In gas plays, the relatively less consolidated Utica offers the most room for big tie-ups between U.S.-based E&Ps while international buyers will continue to consider a range of possibilities to get gas exposure.

"Public-to-public M&A sat out the third quarter, but October shows it is back. We expect more non-core sales from public companies, with assets moving to a mix of public and private buyers. Dwindling core resource also favors continued corporate consolidation, as the companies holding core inventory and premium multiples use their equity to keep building scale," concluded Dittmar.
