Executive summary

Annual revenue of USD 132.699 billion and net income of USD 4.047 billion for the period ended 2025-12-31. This is a structured data brief from filed financial statements, not an independently audited investment opinion.

Business and industry context

Marathon Petroleum Corp is an SEC-reporting issuer listed on NYSE under MPC. Its SEC industry description is Petroleum Refining. This profile organizes annual financial disclosures for research; sector labels are editorial groupings, not GICS classifications. Producers, refiners and service providers respond differently to commodity prices, project spending and capacity utilization.

Financial evidence

The selected fiscal period runs from 2025-01-01 to 2025-12-31. Revenue was USD 132.699 billion; operating income was USD 8.291 billion; diluted EPS was USD 13.22 per share. Prior-period revenue was USD 138.864 billion. The reported revenue change was -4.44%. Comparisons are not adjusted for acquisitions, disposals, foreign exchange or fiscal-week differences.

Profitability and cash generation

Net margin, calculated as net income divided by revenue, was 3.05%. Operating cash flow was USD 8.253 billion; capital expenditure was USD 3.486 billion. Free cash flow (operating cash flow less purchases of property, plant and equipment) was USD 4.767 billion. Missing standard tags are not interpreted as zero. These measures may not be directly comparable between business models.

Balance-sheet context

Total assets were USD 83.955 billion, total liabilities USD 59.869 billion and reported shareholder equity USD 17.314 billion at the period end. Total liabilities include operating obligations and are not a measure of interest-bearing debt.

Valuation context

This release does not include a synchronized market-price dataset. Consequently, price-based multiples are not quoted. P/E requires a dated share price and a clearly identified EPS basis; P/S and P/B require consistently dated capitalization and accounting denominators. A multiple alone does not establish fair value.

Risks and uncertainties

Commodity cycles, project execution, reserve replacement, environmental liabilities and geopolitical exposure. Standardized XBRL can omit custom-tag disclosures. Annual data cannot establish the direction of the latest quarter.

What to monitor

Realized prices, production volumes, refining economics and capital expenditure. Read subsequent quarterly filings, footnotes and accounting-policy changes before interpreting these historical observations.
