Marathon Petroleum Corporation (NYSE: MPC) is an integrated downstream energy company primarily engaged in refining, marketing and transportation of petroleum products. It was established in 2011 when Marathon Oil spun off its refining, marketing and midstream operations to create a standalone corporation. Its roots extend back to 1887 with the founding of The Ohio Oil Company, reflecting a long heritage in the U.S. energy sector. Over the years, Marathon Petroleum has expanded its footprint through strategic acquisitions and organic growth, positioning itself as one of the nation’s largest refiners.
The company’s refining segment operates a network of high-capacity facilities along key U.S. corridors, including the Gulf Coast, Midwest and West Coast. These refineries process a broad slate of crude oils to produce gasoline, diesel, jet fuel, asphalt and petrochemical feedstocks. Marathon Petroleum’s midstream business supports these operations with an extensive system of pipelines, terminals and storage assets, ensuring reliable feedstock supply and product distribution. In the downstream marketing segment, the company sells refined products through wholesale channels and a retail network comprised of company-operated and franchised stations under the Marathon and Speedway banners.
Marathon Petroleum serves customers across the continental United States, with a particularly strong presence in Texas, Louisiana, Ohio and California. Its logistics infrastructure includes joint ventures and partnerships that enhance connectivity between production sites, refineries and end markets. The company’s retail operations encompass thousands of convenience store locations, offering fuel, in-store merchandise and branded loyalty programs. This integrated model enables Marathon Petroleum to capture value across the energy supply chain, from crude sourcing to end-user sales.
Leadership at Marathon Petroleum emphasizes operational excellence, safety and environmental stewardship. Michael J. Hennigan, the company’s President and Chief Executive Officer, oversees strategic initiatives aimed at optimizing asset performance and pursuing low-carbon opportunities. The executive team maintains a focus on regulatory compliance, community engagement and sustainability, with ongoing investments in emissions reduction and efficiency projects. Through a combination of robust infrastructure and experienced management, Marathon Petroleum continues to adapt to evolving energy markets while delivering essential products to businesses and consumers nationwide.
