## Overview

Marathon Petroleum Corp. is a U.S.-based downstream and midstream energy company formed from Marathon Oil's refining business and now organized around refining, logistics, and renewable fuels. It runs one of the largest U.S. refining systems, moves crude oil and refined products through terminals, pipelines, barges and trucks, and also produces and markets renewable diesel.

## Products & services

• Crude oil refining and refined product manufacturing
• Wholesale gasoline, distillates and export sales
• Fuel transportation, storage and terminal logistics
• Natural gas, NGL gathering, processing and transport via MPLX
• Renewable diesel production and marketing
• Branded retail supply through Marathon and ARCO channels

- **Refining & Marketing** (75%) — Refines crude oil and feedstocks, then sells gasoline, distillates and other refined products through wholesale, spot, branded and retail channels.
- **Midstream** (20%) — Moves, stores and processes crude oil, refined products, natural gas and NGLs through MPLX pipelines, terminals and processing assets.
- **Renewable Diesel** (5%) — Processes renewable feedstocks into renewable diesel and markets it through wholesale and contract channels.

- Branded retail supply through Marathon and ARCO channels

## Customers

MPC sells primarily to wholesale marketing customers, spot-market buyers, independent branded retailers, direct dealers and large commercial and industrial end users. Its midstream business serves producers and shippers of crude oil, natural gas and NGLs, while renewable diesel is sold to wholesale customers and contract counterparties. Demand is driven by transportation fuel consumption, refinery logistics needs and producer activity in major U.S. basins.

- **Wholesale marketing customers** (primary) — Buy gasoline, distillates and other refined products for resale or industrial use because MPC can supply large volumes from its refining system.
- **Branded retail operators and direct dealers** (primary) — Independent Marathon-branded outlets and ARCO direct dealers buy fuel supply and brand support to serve retail motorists.
- **Midstream producer customers** (primary) — Oil, gas and NGL producers buy gathering, processing, transport and storage services to move hydrocarbons to market.
- **Export and spot-market buyers** (secondary) — Buy cargoes of refined products when MPC has surplus supply or when regional pricing creates arbitrage opportunities.
- **Renewable diesel customers** (secondary) — Buy renewable diesel under wholesale and contract arrangements to meet low-carbon fuel demand and compliance needs.

- Wholesale fuel marketers buying gasoline and distillates for resale
- Spot-market buyers and export customers seeking cargoes
- Marathon-branded independent operators and ARCO direct dealers
- Commercial and industrial fuel users needing reliable supply
- Oil, gas and NGL producers using MPLX gathering and transport
- Renewable diesel buyers under spot and long-term contracts

## Geography

MPC's refining footprint is concentrated in the Gulf Coast, Mid-Continent and West Coast of the United States, which are the key demand and export corridors for its fuels business. Its midstream assets are tied to major U.S. supply basins such as the Permian, Marcellus and Utica, linking production areas to domestic and international markets. The company also sells refined products internationally through wholesale and export channels, but the business remains heavily U.S.-centric.

- Refineries are concentrated in Gulf Coast, Mid-Continent and West Coast regions
- Midstream assets connect Permian, Marcellus and Utica supply basins
- U.S. terminals, barges, railcars and trucks support domestic distribution
- Wholesale refined products are sold domestically and internationally
- West Coast operations are exposed to stricter fuel specs and regional margins

## Strategy

MPC is investing to improve refinery yields, energy efficiency, emissions performance and product mix, while strengthening its branded marketing footprint. In midstream, MPLX is focused on Permian-to-Gulf Coast integration, long-haul pipelines and new gas processing capacity, and renewable diesel capital is centered on prior joint ventures rather than major new spending.

- **Refinery optimization and high-return capital projects** (medium-term) — Improves product yields, lowers costs and supports margin capture in a volatile refining market.
- **Retail and branded marketing expansion** (medium-term) — Extends reach of Marathon and ARCO channels and improves value capture from refined products.
- **Midstream growth through MPLX** (medium-term) — Adds fee-based cash flow and links producer basins to end markets, reducing reliance on pure refining margins.

- Upgrade refineries to improve yields and capture higher-value products
- Expand branded station presence to strengthen retail value capture
- Invest in emissions reduction and energy efficiency at key refineries
- Grow MPLX through Permian, Marcellus and Utica infrastructure projects
- Maintain renewable diesel operations with limited new capital needs

## Risks

MPC's earnings are highly exposed to refining margin volatility, feedstock costs and regional supply-demand imbalances that are outside management's control. The company also faces operational, regulatory and financial risks tied to large industrial assets, joint ventures, debt levels and low-carbon fuel compliance obligations.

- **Volatile refining margins** [high] — Refined product profitability depends on spreads between crude input costs and product selling prices, which move independently.
- **Feedstock supply and price exposure** [high] — MPC does not produce crude oil feedstocks, so it must compete for supply and can be disadvantaged versus integrated producers.
- **Operational disruption and security events** [medium] — Refineries, pipelines, terminals and marine assets are vulnerable to outages, targeted attacks and other disruptions.
- **Joint venture execution and partner risk** [medium] — MPC shares control in some assets, and partner misalignment or underperformance can hurt returns and operations.
- **Debt and credit profile pressure** [high] — The company carries significant debt, so higher borrowing costs or rating pressure could constrain capital allocation.

- Refining margins can swing sharply with crude and product price spreads
- MPC does not produce its own crude feedstocks, increasing supply exposure
- Joint ventures can create governance and execution risk
- Large assets face outage, disruption and security risks
- Debt and credit ratings matter because the business is capital intensive
- RINs and low-carbon fuel credits can affect compliance costs

## Accounting

The most important accounting judgments are impairment testing for refineries, pipelines and goodwill, because asset values depend on future margins, throughput and discount rates. Investors should also watch how MPC accounts for joint ventures, capitalized maintenance and growth projects, and low-carbon fuel compliance items such as RINs and credits, which can move reported earnings materially.

- **Long-lived asset impairment** — Could materially affect operating income and balance sheet carrying values
- **Goodwill impairment** — A non-cash charge could reduce equity and reported earnings
- **Equity method investment valuation** — Can affect earnings from affiliates and asset values
- **Low-carbon fuel compliance costs** — Affects cost of sales and segment profitability

- Refinery and pipeline impairment tests depend on future cash flow assumptions
- Goodwill is tested at reporting-unit level and can be written down if values fall
- Equity method investments require judgment on recoverability and fair value
- Capital spending and maintenance classification affect operating vs investing cash flow
- RINs and low-carbon fuel credits can create volatile compliance expense
