SM Energy Company and Civitas Resources have recently announced a merger in an all-stock deal valued at around $12.8 billion, including net debt. This strategic move will result in the formation of a combined entity with a vast portfolio spanning approximately 823,000 net acres, predominantly concentrated in the Permian Basin.
As per the merger agreement’s terms, Civitas’ shareholders will receive 1.45 shares of SM Energy stock for each Civitas share they hold. Taking into account the exchange ratio, the companies’ closing share prices on 31 October 2025, and net debt, the combined enterprise value is estimated at $12.8 billion. In consideration, SM Energy will issue roughly 126.3 million shares of common stock.
Both companies’ boards have unanimously approved the transaction, which is anticipated to be completed in the first quarter of 2026, subject to shareholder and regulatory approvals. Following the merger’s conclusion, SM Energy shareholders will possess approximately 48% of the unified company, while Civitas’ shareholders will retain around 52% ownership.
The merged entity will retain the SM Energy name and have its headquarters in Denver, Colorado, US.

He commended Civitas for establishing a leading sustainable energy company in the Permian and DJ basins and looks forward to realizing shareholder value as a cohesive organization.
