About Marathon Petroleum Corp

Marathon Petroleum Corp. (NYSE: MPC) is a United States-based, integrated downstream and midstream energy company headquartered in Findlay, Ohio. For French-speaking investors, the key point is scale: MPC operates the nation’s largest refining system and reports roughly 3 million barrels per calendar day of crude oil refining capacity across 13 refineries. That footprint makes the company one of the most important players in U.S. refining, with a business model closely tied to domestic fuel demand, crack spreads, and logistics efficiency. ([marathonpetroleum.com](https://www.marathonpetroleum.com/About/?utm_source=openai)) MPC’s business is organized around three main areas. Refining & Marketing converts crude oil into transportation fuels and other refined products for the U.S. market and for export. Midstream is largely conducted through MPLX, MPC’s sponsored master limited partnership, which owns and operates crude and product pipelines, terminals, storage, towboats and barges, and also gathers, processes, transports, fractionates and markets natural gas liquids. The company also has a Renewable Diesel component, giving it exposure to lower-carbon fuel offerings alongside its traditional petroleum portfolio. ([marathonpetroleum.com](https://www.marathonpetroleum.com/Operations/Midstream/?utm_source=openai)) From a competitive standpoint, MPC benefits from integrated assets, large-scale refinery operations, and a logistics network that links refining, transportation and marketing. Its branded retail and wholesale presence spans the United States under Marathon and ARCO, with operations that also reach into Northern Mexico. That domestic focus gives the company a strong position in North American fuel markets and helps it capture value across the downstream chain.

In its February 2026 full-year 2025 results, MPC reported strong refining operations, 94% full-year refining utilization, meaningful cash generation, and substantial capital returned to shareholders. Management also emphasized that growing MPLX distributions support MPC’s capital-return profile and help differentiate the company from peers. In May 2026, MPC announced a leadership change in Investor Relations, underlining an active market communication strategy.
