How Marathon Petroleum Corporation Makes Money

Marathon Petroleum generates revenue through three integrated business segments that span the entire downstream petroleum value chain from crude oil acquisition to refined product delivery. The Refining & Marketing segment is the core of the business, generating the majority of revenue and operating income. This segment refines crude oil and other feedstocks at 16 refineries across the Gulf Coast, Midwest, and West Coast regions of the United States, with total capacity of approximately 3.0 million barrels per day. In 2024, the segment processed 2,714 thousand barrels per day of crude oil, sourced 68% from the United States, 22% from Canada, and 10% from other international sources. The refineries produce gasoline, distillates, NGLs, petrochemicals, asphalt, propane, and heavy fuel oil, with total refined product sales of 3,585 thousand barrels per day in 2024. Gasoline accounted for 1,922 mbpd of sales, distillates for 1,187 mbpd, and other products for the remainder. Revenue is generated through the sale of refined products to wholesale customers, independent retailers, direct dealers, airlines, transportation companies, utilities, and export markets. The company also purchases refined products and ethanol for resale, optimizing its supply chain through an integrated logistics network. The Refining & Marketing segment generated adjusted EBITDA of $5.7 billion in 2024, down from $13.7 billion in 2023, reflecting the compression of refining margins as crack spreads normalized from the elevated levels of 2022. The segment's profitability is driven by the margin between refined product prices and crude oil costs—the 3-2-1 crack spread—multiplied by throughput volume and capture rate. Marathon Petroleum achieved a 99% commercial capture rate in 2024, meaning the company realized nearly the full theoretical margin available from market crack spreads, a testament to its operational and commercial execution. The Midstream segment, conducted primarily through MPLX LP, owns and operates crude oil and light product transportation and logistics infrastructure, as well as gathering, processing, and fractionation assets. MPLX generated $6.5 billion in segment adjusted EBITDA in 2024, up 6% from 2023, demonstrating the durability of fee-based midstream cash flows even during refining margin downturns. MPC owns approximately 647 million MPLX common units, representing a majority stake, and received $2.27 billion in limited partner distributions in 2024. The annualized distribution from MPLX to MPC is expected to reach $2.5 billion, a figure that management has emphasized will more than fund MPC's standalone dividend and capital expenditures. MPLX's assets include approximately 21,000 miles of pipeline, 40 million barrels of terminal storage capacity, 559 transport trucks, approximately 13,550 rail tank cars, and 348 vessels and barges. The midstream segment also includes natural gas processing capacity of approximately 12.4 billion standard cubic feet per day and NGL fractionation capacity of 829,000 barrels per day. The Renewable Diesel segment, established in Q4 2024 as a separate reportable segment, includes renewable diesel activities previously reported within Refining & Marketing. The segment's primary asset is the Martinez Renewables joint venture with Neste in Martinez, California, which reached full production capacity of 730 million gallons per year in late 2024. The facility produces renewable diesel with significantly lower carbon intensity than traditional diesel. MPC also owns a biodiesel production facility in Cincinnati, Ohio with capacity of approximately 80 million gallons per year, and holds ownership interests in ethanol production facilities in Albion, Michigan; Clymers, Indiana; and Greenville, Ohio with combined capacity of approximately 410 million gallons per year. In 2024, MPC produced nearly 600 million gallons of renewable fuels and delivered approximately 2.8 billion gallons of renewable fuels to market, making it one of the largest marketers of renewable fuels in the United States. The segment generated negative adjusted EBITDA of $150 million in 2024, reflecting the early-stage nature of the business and joint venture accounting. Revenue recognition in the refining business follows standard commodity sales patterns, with revenue recognized upon delivery of refined products. The company's integrated logistics network—pipelines, terminals, trucks, railcars, ships, and barges—enables optimization of crude acquisition costs and refined product placement, capturing value that non-integrated competitors cannot access. Marathon Petroleum's capital allocation framework prioritizes maintaining an investment-grade credit profile, funding sustaining and growth capital, and returning at least 50% of discretionary free cash flow to shareholders through dividends and share repurchases. The company paid quarterly dividends of $0.91 per share in 2025, for an annual dividend of $3.64 per share and a yield of approximately 1.42%. Capital returns totaled $4.5 billion in 2025 and $10.2 billion in 2024, the latter representing a 23% capital return yield.

Marathon Petroleum's growth strategy is built on four pillars: operational excellence in refining, midstream growth through MPLX, renewable fuels expansion, and disciplined capital allocation. In refining, the company is making multiyear investments across its Gulf Coast, West Coast, and Mid-Continent value chains to enhance margins, reduce costs, and optimize systems. These investments include capacity expansions, reliability improvements, and energy efficiency projects that are expected to drive peer-leading profitability per barrel. The company's 2025 refining utilization of 94% and margin capture of 105% demonstrate the execution capability of this strategy. In midstream, MPLX is investing in natural gas and NGL infrastructure to support increased producer activity, particularly in the Permian Basin and Marcellus Shale. The Gulf Coast fractionation complex and export terminal will create a fully integrated NGL value chain from wellhead to water, connecting Permian Basin production to global LPG markets. MPLX's distribution growth—expected to reach $2.5 billion annualized to MPC—provides a stable, growing cash flow that funds shareholder returns. In renewable fuels, the company is leveraging the Martinez Renewables facility and its existing biofuel production capacity to capture growing demand for low-carbon transportation fuels. The company delivered approximately 2.8 billion gallons of renewable fuels in 2024 and is positioned to expand this business as regulatory mandates tighten. Capital allocation remains disciplined: the company targets returning at least 50% of discretionary free cash flow to shareholders, with quarterly dividends of $0.91 per share and opportunistic share repurchases. The company maintains an investment-grade credit profile and prioritizes sustaining and regulatory capital before growth investments. The 2020 sale of Speedway to 7-Eleven for $21 billion demonstrated management's willingness to divest non-core assets to strengthen the balance sheet and focus on the integrated refining-midstream model.
