Item 8.01 Other Events.
On August 26, 2026, the Board of Directors of HF Sinclair Corporation (the "Corporation") authorized a new $1.5 billion share repurchase program (the "New Share Repurchase Program"), effective August 26, 2026. The New Share Repurchase Program replaces all existing share repurchase authorizations, of which there was approximately $11 million remaining under the Corporation's prior share repurchase program initially authorized in May 2024. Share repurchases under the New Share Repurchase Program may be made in the open market or through privately negotiated transactions from time to time or by other means in accordance with federal securities laws. The New Share Repurchase Program also authorizes privately negotiated repurchases from REH Advisors Inc. ("REH"), subject to REH's interest and other limitations. The timing and amount of share repurchases under the New Share Repurchase Program will depend on market conditions and corporate, tax, regulatory and other relevant considerations. The New Share Repurchase Program may be discontinued at any time by the Board of Directors of the Corporation. In addition, the Corporation is authorized by the Board of Directors to repurchase shares in an amount sufficient to offset shares issued under the Corporation's compensation programs.
