Direct Answer
O'Reilly Automotive reports a single business segment in its fiscal 2025 Form 10-K, so the whole company is managed and measured as one business. That segment's revenue was $17.8 billion (up 6.4% from the prior year), and its largest cost line was cost of goods and services sold at 48% of revenue, leaving net income of $2.5 billion.
How Does O'Reilly Automotive Make Money?
Since 2024, US accounting rules (ASU 2023-07) require even a single-segment company to disclose the significant expense categories its management reviews. These are the amounts O'Reilly Automotive tags to its one segment, as a share of that segment's revenue.
| Line | FY2025 | FY2024 | Share of revenue |
|---|---|---|---|
| Revenue from contract with customer excluding assessed tax | $17.8 billion | $16.7 billion | 100.0% |
| Cost of goods and services sold | $8.6 billion | $8.2 billion | 48.4% |
| Depreciation and amortization | $415 million | $373 million | 2.3% |
| Interest expense debt | $235 million | $223 million | 1.3% |
| Net income | $2.5 billion | $2.4 billion | 14.3% |
What a Single Segment Does and Does Not Tell You
One reportable segment means management runs O'Reilly Automotive as one business; it does not mean the company sells one product. Revenue can still be spread across products, customers and countries that the filing describes in its revenue note or Item 1 without tagging them as segments. Cost lines are the company's own categories, so they compare across years within O'Reilly Automotive more safely than against another company, and lines that are not listed are included in other expense totals rather than missing.
Where These Numbers Come From
Every figure on this page is a value O'Reilly Automotive reported in the segment note and revenue disclosures of its Form 10-K filed February 27, 2026 (accession 0000898173-26-000009), read from the SEC's Financial Statement Data Sets. The prior-year column is the comparative figure from that same filing, so it reflects any restatement for a change in segments. Category names are the company's own XBRL labels, lightly reformatted for reading.
Rows that only total other rows (for example a "Products" line beside the individual products) are left out so nothing is counted twice. This page is educational and describes reported history for fiscal 2025; it is not a forecast or a recommendation.
