MARATHON OIL CORP

Marathon Oil Corp marshals upstream oil and gas capabilities—exploration, development, and production of hydrocarbons with a focus on U.S. shale plays and select international acreage—to serve refiners, wholesale purchasers, and strategic partners needing reliable energy feedstocks; the company is generally associated with SIC 1311 even though the industry listing in this profile is unspecified, underscoring its placement in traditional extraction and production markets. Its capital-intensive operations depend on commodity-price cycles, regulatory approvals, and environmental compliance, so material risks include volatile crude and gas prices, cost inflation, and evolving climate and permitting regimes overseen by federal and state agencies; the latest filing status is not available here, yet transparency remains a priority, reflected in ongoing disclosures to investors.
