# Marathon Petroleum: Competitors & Industry Structure

## Direct Answer

SEC EDGAR classifies Marathon Petroleum under SIC code 2911 (Petroleum Refining). Among Swoopr's S&P 500 Equal Weight companies, 9 others share that classification; by latest reported revenue, Marathon Petroleum ranks 4 of 10. A filing classification is a starting point: a company's real competitors depend on its segments, which its 10-K describes.

Revenue growth compares each company's latest fiscal year with the one before. Fiscal years do not always end on the same date, so treat close comparisons with care.

## How Does Marathon Petroleum Rank Among All SEC Filers in Its Industry Code?

10 companies with annual reports in Swoopr's SEC dataset share SIC code 2911 (Petroleum Refining), a wider group than the S&P 500 Equal Weight companies above. Ranks run from 1 (highest) and use each company's latest fiscal year, in U.S. dollars.

| Measure | Marathon Petroleum | Median of filers | Rank |
| --- | --- | --- | --- |
| Revenue | $133 billion | $128 billion | 4 of 10 |
| Revenue growth | -4.4% | -5.3% | 3 of 10 |
| Operating margin | 6.2% | 2.6% | 1 of 5 |
| Net margin | 3.0% | 3.2% | 6 of 10 |

A SIC code reflects the filer's main business as the SEC records it, so the group mixes companies of very different size; the median is a better guide than the average, and a rank near the top by revenue says nothing about quality.

## Where These Numbers Come From

Every figure on this page is a value Marathon Petroleum reported in its own SEC filings, read from the SEC's XBRL data (accession 0001510295-26-000009 for fiscal year 2025). Ratios are computed from those reported values. Figures were retrieved on October 12, 2026; a later amendment or a new annual report can change them, and the filing itself always takes precedence over this summary.

Each fiscal year is labeled by the calendar year in which it ended, so a company that names the same period differently in its own filings (many retailers whose year ends in January) may use another label. A year is left out of the table when the SEC data set holds no value for it. A figure shown as "Not reported" means the company did not file a value under the standard tag Swoopr reads, not that the amount was zero. This page is educational and describes reported history only; it is not a forecast or a recommendation.
