Marathon Pete Stock Price, News & Analysis

Marathon Petroleum Corporation (NYSE: MPC) is an integrated downstream and midstream energy company in the petroleum refineries industry. Headquartered in Findlay, Ohio, MPC operates what it describes as the nation’s largest refining system and participates across refining, marketing, and midstream logistics. The company is classified in the manufacturing sector and focuses on converting crude oil into refined products and moving hydrocarbons and fuels through extensive transportation and storage infrastructure.

According to company disclosures, Marathon Petroleum’s refining system spans multiple U.S. regions. A prior description notes that MPC is an independent refiner with 13 refineries in the mid-continent, West Coast, and Gulf Coast of the United States with a total throughput capacity of about 3.0 million barrels per day. The company also reports that its refining and marketing operations achieved total throughput of 3.0 million barrels per day in the third quarter of 2025, supported by high crude capacity utilization. These refining assets are central to MPC’s role in the petroleum refineries industry.

Integrated downstream and midstream model

MPC describes itself as a leading integrated downstream and midstream energy company. On the downstream side, the company operates its large refining system and a marketing network that includes branded locations across the United States, including Marathon brand retail outlets. This marketing system enables MPC to distribute refined products through branded channels, connecting its refineries to end markets.

On the midstream side, Marathon Petroleum owns the general partner and a majority limited partner interest in MPLX LP, a master limited partnership that owns and operates midstream energy infrastructure. MPLX’s assets, as described in recent disclosures, include gathering, processing, and fractionation assets, as well as crude oil and light product transportation and logistics infrastructure. Through this relationship, MPC has access to pipelines, processing plants, fractionation facilities, terminals, and related logistics that support the movement and handling of crude oil, refined products, natural gas, and natural gas liquids.

Renewable diesel capabilities

In addition to conventional refining, Marathon Petroleum has renewable diesel production capacity. A prior description notes that MPC’s Dickinson, North Dakota, facility produces renewable diesel, and its Martinez, California, facility has the ability to produce renewable diesel as well. These facilities contribute to the company’s renewable diesel segment, which is reported separately from its Refining & Marketing and Midstream segments in financial disclosures. The renewable diesel segment reflects MPC’s participation in lower-carbon fuel production within its broader downstream portfolio.

Business segments and operations

MPC’s results are discussed in terms of three primary segments:

• Refining & Marketing (R&M) – This segment encompasses the refining of crude oil and other feedstocks into products and the marketing of those products. The company reports R&M segment adjusted EBITDA and per-barrel metrics, including R&M margin and refining operating costs per barrel. Refining operating costs and planned turnaround costs are tracked to assess segment performance.
• Midstream – This segment is largely represented by MPLX LP. It includes midstream energy infrastructure such as crude oil and refined product pipelines, natural gas and NGL gathering and processing, and fractionation capacity. MPC highlights midstream segment adjusted EBITDA and notes that midstream performance is driven by rates, throughputs, acquisitions, and operating expenses.
• Renewable Diesel – This segment reflects the performance of MPC’s renewable diesel operations. The company reports renewable diesel segment adjusted EBITDA and utilization metrics, indicating how these assets contribute to overall results.

These segments are supported by corporate-level functions, with corporate expenses separately disclosed in financial updates.

Relationship with MPLX LP

Marathon Petroleum’s ownership of the general partner and majority limited partner interest in MPLX LP connects the refining and marketing operations with extensive midstream infrastructure. MPLX is described as a large-cap master limited partnership that owns and operates midstream energy infrastructure and logistics assets and provides fuels distribution services. Its assets include crude oil and refined product pipelines, inland marine operations, light-product terminals, storage caverns, refinery tanks, docks, loading racks, associated piping, and marine terminals, as well as crude oil and natural gas gathering systems and natural gas and NGL processing and fractionation facilities in key U.S. supply basins.

This relationship allows MPC to access midstream services for its refining system and marketing operations. MPC also notes that distributions from MPLX represent a significant source of cash flows to the corporation.
