SM Energy Company has closed its all-stock merger with Civitas Resources, Inc. following shareholder approval at special meetings held Jan. 27. The combined company will continue operating under the SM Energy name. 

The transaction creates a larger, oil-focused U.S. independent with a broader footprint across core shale basins, including an expanded position in the Permian Basin. Management has previously outlined plans to capture $200–$300 million in annual synergies and pursue at least $1 billion in asset divestitures over the next year as part of its post-merger integration strategy.

Leadership appointments announced with the deal include Beth McDonald as president and CEO and Blake McKenna as executive vice president and COO. The board of directors has expanded to 11 members, with representation from both legacy companies.

SM Energy said it plans to discuss its 2025 financial results and 2026 operating outlook on a conference call scheduled for late February.
