SM Energy and Civitas Resources announced on 3 November that they have entered into a definitive agreement to merge in an all-stock transaction valued at approximately $12.8 billion, including each firm's debt.
The merger will create one of the largest oil-focused independent producers in the US, with a combined portfolio of nearly 823,000 net acres, including 248,500 net acres in the Permian Basin. With a combined production profile of 526,000 BOE/D, the merged company will rank fourth among US oil-focused independents by output, behind Devon Energy, Coterra Energy, and Ovintiv.
The combined company expects 2025 free cash flow to top $1.4 billion and to achieve annual cost synergies of about $200 million, with an upside potential of $300 million. The cost savings will come from reduced general and administrative costs, improved drilling and completion efficiencies, lower operational expenses, and a reduced cost of capital.
“This strategic combination creates a leading oil and gas company with enhanced scale, numerous value-adding synergies, and significant free cash flow,” said Herb Vogel, CEO of SM. “Together, we look forward to unlocking stockholder value as a unified organization.”
The merger announcement also noted that the combined company will hold more than 1.4 billion BOE of reserves and nearly 2,400 net drilling locations.
“By combining our strong technical teams and complementary assets, we gain scale, sharpen our competitive edge, and strengthen our ability to responsibly produce energy that contributes to energy security and prosperity,” Civitas’ interim CEO, Wouter van Kempen, said in the announcement.
The merger follows SM Energy’s $2.6-billion purchase of XCL Resources’ Uinta Basin assets in Utah in 2024. A year earlier, Civitas expanded its portfolio with nearly $7 billion in acquisitions from Tap Rock Resources, Hibernia Energy, and Vencer Energy.
Enverus Intelligence Research (EIR) said the merger lifts fourth-quarter deal value to nearly $10 billion, matching the total recorded in the third quarter with 2 months still remaining in the year.
EIR said recent consolidation across the North American shale sector shows that the most attractive opportunities remain among smaller oil-focused producers and gas-sector mergers and acquisitions. The firm added that corporate transactions continue to offer the clearest path to value creation, with the potential for more noncore asset sales by public companies aiming to cut debt and mitigate the impact of weaker crude prices.
“Market participants seem more comfortable with the outlook for commodity prices and are turning to [mergers and acquisitions] to position themselves for success, whether that is securing gas supply as prices strengthen or merging oil companies to be better positioned to navigate low crude with synergies and deleveraging,” said Andrew Dittmar, principal analyst at EIR.
Under the terms of the agreement, Civitas stockholders will receive 1.45 shares of SM common stock for each Civitas share. Upon closing, Civitas shareholders will own approximately 52% of the combined company, while SM shareholders will own about 48%. The merged company will operate under the SM name and remain based in Denver, Colorado, the current headquarters for both firms.
Following the transaction, the new company’s board will be formed by 11 members, six from SM and five from Civitas. Vogel will continue as CEO, with the previously announced leadership transition to Beth McDonald, current president and COO of SM Energy, upon Vogel's retirement on 1 March 2026.
The boards of both companies have unanimously approved the merger, which is expected to close in the first quarter of 2026, pending customary closing conditions.
