How O'Reilly Automotive Makes its Money: Revenue Breakdown

How Does O’Reilly Automotive Make its Money?

O’Reilly Automotive is one of the three largest auto parts retailers in the United States, operating 6,590 stores across the U.S. (6,450), Mexico (112), and Canada (26) as of fiscal year 2025. Founded in 1957 in Springfield, Missouri, and headquartered there today, the company sells replacement auto parts, tools, accessories, chemicals, and maintenance items to two distinct customer types: do-it-yourself (DIY) consumers who repair their own vehicles, and professional service providers — repair shops, mechanics, and fleet operators — who buy parts for installation in their shops (referred to as DIFM, or “do-it-for-me”).

O’Reilly generated $17.8B in total revenue in fiscal year 2025 (ended December 31, 2025), up 6.4% from $16.7B in FY2024. A defining characteristic of the current business: for the first time in company history, professional (DIFM) revenue is nearly equal to DIY revenue — the two segments now each account for approximately 49% of total sales, reflecting a decade-long strategic push to deepen relationships with commercial repair shops.

O’Reilly Automotive (ORLY) Business Model

O’Reilly makes money by selling auto parts at retail and wholesale prices through its store network and online channels. The business model has two economic engines:

1. Retail DIY sales — Consumers come in to buy parts for home repairs. Gross margins on retail are relatively high because O’Reilly sells at full retail pricing with limited price competition (most DIYers need the right part today, not in two days). O’Reilly differentiates on parts availability and knowledgeable counter staff (called “team members”) who help customers identify and select the correct part.

2. Commercial/Professional (DIFM) sales — O’Reilly sells parts at negotiated wholesale prices to repair shops and fleets. Margins are lower than retail but volume per account is much higher, and the relationships are stickier. O’Reilly competes for professional accounts by offering fast delivery (often within 30 minutes of a repair shop), an industry-leading SKU count, and a hub-and-spoke distribution system that keeps slow-moving parts available without requiring every store to stock them.

The hub-and-spoke distribution network is the operational backbone. O’Reilly operates regional distribution centres that supply stores daily, with some stores serving as hubs supplying nearby spoke stores with less-common parts. This network allows stores to offer a much broader parts catalogue than they could stock physically — a meaningful competitive advantage in a business where “do you have it in stock?” is often the deciding factor in where a professional shop orders from.

O’Reilly does not manufacture parts. It sources from a wide range of suppliers and sells under both national brand names and its own private label brands. Private label parts carry higher margins and are a growing part of the mix.

Revenue Breakdown

FY2025 ended December 31, 2025. Financial data sourced from O’Reilly Automotive SEC Filings.

DIY Customer Revenue — 49% of Revenue

DIY revenue reached $8.77B in FY2025, up 3.5% from $8.47B in FY2024. This segment serves consumers buying parts for home repairs — oil filters, brake pads, batteries, wiper blades, and thousands of other maintenance and repair items. DIY customers typically pay full retail price and often need counter staff assistance to identify the correct part for their vehicle.

Growth in the DIY channel is driven by store count expansion (182 net new U.S. stores in FY2025) and comparable store sales growth of 4.7% in FY2025. The secular tailwind is the aging U.S. vehicle fleet — the average age of vehicles on U.S. roads has exceeded 12 years, meaning more vehicles need more frequent repairs, generating sustained demand for replacement parts.

DIY carries higher gross margins than the professional segment because retail pricing is not subject to the negotiated discounts extended to commercial shop accounts.

Professional Service Provider Revenue — 49% of Revenue

Professional revenue hit $8.65B in FY2025, up 10.4% from $7.84B in FY2024 — growing at three times the rate of DIY. This is the most strategically important trend in O’Reilly’s business. The professional channel serves independent repair shops, dealership service departments, and fleet operators who buy parts in volume under negotiated pricing agreements.

O’Reilly has invested heavily in the infrastructure required to win professional accounts: dedicated commercial sales teams, faster delivery logistics, expanded distribution centre capacity, and a wider SKU catalogue accessible through the hub-and-spoke network. Professional accounts are valuable because they place large, recurring orders and rarely switch suppliers once a reliable parts relationship is established.

The shift toward a near 50/50 revenue split between DIY and professional is a meaningful mix shift — professional accounts spend more per transaction but at lower margins, which partially explains the slight gross margin compression from FY2022 peaks.

Other Sales & Adjustments — 2% of Revenue

A small catch-all segment covering items such as gift cards, chemical and fluid products, and inter-store adjustments. Not a strategic growth driver.

O’Reilly Automotive (ORLY) Key Financial Metrics

• Gross Margin: 51.6% — Exceptionally high for a brick-and-mortar retailer. For comparison, Home Depot’s gross margin is approximately 33%. O’Reilly’s 51%+ reflects meaningful pricing power, private label penetration, and the essential, non-discretionary nature of auto parts purchases.
• Operating Margin: 19.5% — Among the highest operating margins in physical retail. This reflects operating leverage from scale, disciplined SG&A management, and the high gross margin base. O’Reilly’s operating margin has been in the 19–22% range consistently over the past five years.
• Revenue Growth: +6.4% — Accelerated from 5.7% in FY2024, driven by professional segment outperformance and 208 net new stores globally.
• Comparable Store Sales Growth: +4.7% — A critical retail metric showing that existing stores are growing, not just new store openings. Positive comps mean each location is selling more on average year-over-year.
• Free Cash Flow: $1,593M — FCF declined from $2,026M in FY2024, reflecting higher capital expenditures from accelerated store openings and distribution centre expansion.

Is O’Reilly Automotive Profitable?

Yes, O’Reilly Automotive is highly profitable. The company reported net income of $2.54B on $17.78B in revenue in FY2025, a net margin of 14.3%. Operating income was $3.46B, an operating margin of 19.5% — well above the retail sector average of approximately 5–8%.

O’Reilly has been consistently profitable for decades. The company uses the majority of its free cash flow ($1.59B in FY2025) to repurchase shares rather than pay dividends. O’Reilly has reduced its share count from over 1 billion shares in 2020 to approximately 842 million in FY2025 — a 16% reduction — which mechanically grows EPS even when net income is flat. EPS grew 9.6% in FY2025 ($2.97 vs $2.71) despite net income growing only 6.3%, illustrating the EPS amplification effect of buybacks.

Where Does O’Reilly Spend its Money?

• Cost of Revenue ($8,608M / 48% of revenue): The cost of purchasing parts from suppliers, inbound freight, and distribution centre operations. O’Reilly’s buying power — sourcing at scale from thousands of suppliers — is a key competitive advantage that keeps cost of goods competitive.
• Selling, General & Administrative ($5,714M / 32% of revenue): Store labour, store occupancy (rent), corporate overhead, and advertising. Labour is the largest component — every O’Reilly store employs knowledgeable counter staff, which is a deliberate competitive differentiator but also a significant cost.
• Capital Expenditures: Not reflected in the income statement but approximately $800M+ annually, covering new store construction, distribution centre expansion, and technology infrastructure. O’Reilly opened 208 net new stores in FY2025.

O’Reilly Automotive (ORLY): What to Watch

1. Professional segment mix — Pro revenue grew 10.4% in FY2025 vs. 3.5% for DIY. If this trend continues, professional will become the majority of revenue within a few years. This affects margin structure (professional is lower-margin) but improves revenue stability and account stickiness.
2. Comparable store sales growth — The 4.7% comp in FY2025 was strong. Sustaining positive comps as new stores mature and the vehicle fleet stabilises is the key operational metric to watch.
3. International expansion — O’Reilly opened 25 net new stores in Mexico in FY2025 (to 112 total) and is growing its Canadian footprint. These markets offer long runway compared to a maturing U.S. market but carry higher execution risk.
4. EV impact on parts demand — Electric vehicles have significantly fewer wear parts than internal combustion vehicles (no oil changes, fewer brake replacements due to regenerative braking, no timing belts). The EV transition is a long-term structural headwind, though the current U.S. fleet is 99%+ ICE and the transition will take decades.
5. Share buyback sustainability — O’Reilly carries substantial debt to fund buybacks ($235M in interest expense in FY2025). As rates have risen, the cost of this leverage has increased. Investors should monitor whether buyback pace is sustained or reduced.
