Energy Advisors Group has released our 2025 M&A Recap with an updated 2026 Outlook.
Inside you'll find trends since 2010 on valuation multiples for oil and gas, deal sizes and areas. We also have a Special Section looking at U.S. focused mergers since 1980. We are currently in a consolidaton wave that began in 2023 driven by shale maturities and lower relative oil prices.
As an addendum, we have a Supplemental Report that captures all of 2025's significant deals in a report that is available upon request.
Here's some quick highlights of current market themes.
Market Themes:
------- 2026 Is Off To A Strong Start. Through February 18, there's been $37B in deals, up >55% over all of 4Q2025 led by Devon's merger with Coterra ($25.3B).
------- More Large Deals Are In The Works. Including Exxon's Eagle Ford exit, Ascent Resources (Utica) courtship, a potential exit offshore by Beacon and Conoco looking to offload another $2B. The market is also awaiting any firm plans regarding asset rationalization (Marcellus, Anadarko, Eagle Ford) coming from the Devon-Coterra merger.
------- International Buying Momentum. Mitsubishi just made its largest ever corporate buy paying $7.5B for Haynesville Aethon. This followed other Japanese buys from JERA and JAPEX. Offshore, UK's largest independent Harbour Energy paid $3.2B for deepwater focused LLOG.
------- Consolidation. The US oil & gas industry has gone through multiple waves of consolidation dating back to 1980. We've tracked these over time. The current wave began in 2023 and has now seen 15 public E&Ps exit.
------- Private Equity Is Hunting. Adding to the competitive pressure for PDP assets with running room for expert development are 15+ seasoned team that are re-booting and armed with $5B+ in private equity backing. We expect to see more buying from this group in 2026.
