Company Overview

Marathon Petroleum Corporation (MPC) functions as a prominent integrated energy enterprise, primarily concentrating its downstream operations across the United States. Its business is bifurcated into two main divisions: Refining & Marketing, and Midstream. The Refining & Marketing segment is responsible for processing crude oil and various other raw materials at its refineries, strategically located in the U.S. Gulf Coast, Mid-Continent, and West Coast regions. This division also acquires refined petroleum products and ethanol for subsequent distribution. Key outputs from this segment encompass a diverse array of transportation fuels, including different gasoline blends, heavy fuel oil, and asphalt. Additionally, it manufactures chemicals such as aromatics, propane, propylene, and sulfur. MPC sells these refined goods through multiple channels, including wholesale marketers domestically and globally, purchasers on the open spot market, and independent entrepreneurs who manage primarily Marathon-branded retail locations. It also supplies fuel via long-term agreements to direct dealer sites, predominantly under the ARCO brand. The Midstream segment handles the comprehensive movement, storage, distribution, and commercialization of crude oil and refined products. This is achieved through its extensive network of refining logistics assets, pipelines, terminals, towboats, and barges. Moreover, this segment engages in the collection, processing, and transportation of natural gas, alongside the gathering, transport, fractionation, storage, and marketing of natural gas liquids. By December 31, 2021, the corporation supported 7,159 branded jobber retail points, managed by independent entrepreneurs, spanning 37 U.S. states, the District of Columbia, and Mexico. Marathon Petroleum Corporation, established in 1887, maintains its corporate headquarters in Findlay, Ohio.

Frequently Asked Questions

What is the PE ratio of MPC?

The trailing twelve-month PE ratio of MPC reflects how much investors pay per dollar of Marathon Petroleum Corporation's earnings. This metric is most useful when compared to Oil & Gas Refining & Marketing peers and the company's own historical range.

Is MPC overvalued based on PE ratio?

MPC's PE of 20.1x combined with a PEG ratio of 0.18 provides a growth-adjusted perspective. A PEG below 1.0 means the P/E is low relative to the earnings growth rate. Keep in mind that PE-based valuation works best for profitable, mature companies — for high-growth or cyclical Oil & Gas Refining & Marketing, a DCF analysis may be more appropriate.

How do I value MPC stock using PE ratio?

To value Marathon Petroleum Corporation using PE: (1) Compare the current PE (20.1x) against the Oil & Gas Refining & Marketing median to assess relative pricing, (2) check the PEG ratio (0.18) to adjust for growth expectations, (3) review the 5-year PE range to identify where the stock sits historically, and (4) estimate fair value by multiplying a target PE by forward EPS estimates. This relative approach complements DCF's absolute valuation.

What is the PEG ratio of MPC?

MPC's PEG ratio is 0.18, calculated by dividing the PE ratio (20.1x) by the expected earnings growth rate. A PEG below 1.0 means the P/E is low relative to the expected earnings growth rate. Note that PEG accuracy depends on the reliability of growth estimates.

Should I use PE ratio or DCF for MPC stock valuation?

PE ratio gives a quick relative read — how MPC is priced versus Oil & Gas Refining & Marketing peers. DCF provides an absolute value based on projected free cash flows. For MPC, with a strong ROE of 27.3%, both methods are worth using — PE for a market-relative check, DCF to stress-test whether fundamentals justify the price. Each method has blind spots: PE ignores capital structure and cash flow quality, while DCF is sensitive to growth and discount rate assumptions.
