HF Sinclair Corporation is a U.S.-based independent energy company formed in 2022 through the combination of HollyFrontier and Sinclair Oil assets. Headquartered in Dallas, Texas, the company operates a network of complex refineries primarily in the Midcontinent, Rocky Mountain and Southwest regions, producing transportation fuels such as gasoline, diesel and jet fuel, as well as asphalt and other refined products. It supplies fuel to wholesale markets and the Sinclair-branded retail network.
HF Sinclair also manufactures lubricants and specialty products, including base oils, white oils, petrolatum, waxes and other performance fluids, serving industrial, automotive and consumer end markets. The company has been expanding renewable diesel production by converting and modifying select refineries. Its logistics are supported through a majority interest in Holly Energy Partners, which owns and operates pipelines and storage terminals that move and store crude oil and refined products.
