February 04, 2026 [SM Energy]- SM Energy Company (“SM Energy” or the “Company”) (NYSE: SM) announced today the closing of its all-stock merger with Civitas Resources, Inc. (“Civitas”) (NYSE: CIVI) (the “Transaction”). The Transaction was approved by stockholders of both companies at special meetings held on January 27, 2026. The combined company continues to trade under the ticker symbol “SM” and will retain the name SM Energy Company.

As previously announced, upon the closing of the Transaction, Beth McDonald was appointed President and Chief Executive Officer and joined the Company’s Board of Directors (the “Board”), and Blake McKenna was appointed Executive Vice President and Chief Operating Officer. Additionally, the Company’s Board was increased to 11 members, comprising six representatives from SM Energy and five from Civitas. Julio Quintana remains Non-Executive Chairman of the Board. Other members of the Board include Bart Brookman, Morris Clark, Carrie Fox, Billy Helms, Beth McDonald, Ramey Peru, Rose Robeson, Wouter van Kempen, Ashwin Venkatraman, and Howard Willard III.

SM Energy President and Chief Executive Officer Beth McDonald commented: “Today’s close marks the start of our work together as one SM, a top 10 U.S. independent oil-focused producer, with a larger, complementary footprint across the highest‑return U.S. shale basins—including a premier Permian position. We are focused on effectively integrating the two companies to unlock additional free cash flow by achieving our previously announced annual synergy target of $200 to $300 million and executing our previously announced divestiture target of at least $1.0 billion over the next year. We expect these steps to further strengthen our balance sheet, accelerate our return of capital to stockholders, and drive considerable upside in our equity. We look forward to sharing our 2026 operating plan and our updated return of capital framework on our upcoming conference call in late February.”
