Segments
The company operates through three segments: Refining & Marketing, Midstream and Renewable Diesel.
Refining & Marketing
Refining & Marketing – refines crude oil and other feedstocks at our refineries in the Gulf Coast, Mid-Continent and West Coast regions of the United States, purchases refined products and ethanol for resale and distributes refined products through transportation, storage, distribution and marketing services provided largely by our Midstream segment. The company sells refined products to wholesale marketing customers domestically and internationally, to buyers on the spot market, to independent entrepreneurs who operate primarily Marathon branded outlets and through long-term supply contracts with direct dealers who operate locations mainly under the ARCO brand.
Refineries
The company owns and operates refineries in the Gulf Coast, Mid-Continent and West Coast regions of the United States with an aggregate crude oil refining capacity of 2,963 mbpcd. During 2024, the company’s refineries processed 2,714 mbpd of crude oil and 208 mbpd of other charge and blendstocks.
The company’s refineries include crude oil atmospheric and vacuum distillation, fluid catalytic cracking, hydrocracking, catalytic reforming, coking, desulfurization and sulfur recovery units. The refineries process a wide variety of condensate and light, and heavy crude oils purchased from various domestic and foreign suppliers. The company produces numerous refined products, ranging from transportation fuels, such as reformulated gasolines, blend-grade gasolines intended for blending with ethanol and ULSD fuel, to heavy fuel oil and asphalt. Additionally, the company manufactures NGLs and petrochemicals and propane.
