O'Reilly Automotive (ORLY) Q3 2026 earnings review
O'Reilly store sales accelerate, while tariff refunds lift its profit
O'Reilly Automotive, the auto parts retailer, accelerated store sales growth when its prior plan pointed to a second-half slowdown. Comparable store sales rose 7.2% as professional repair shops and do-it-yourself drivers both spent more, and chief executive Brad Beckham raised the full-year outlook across the board. However, a $39 million tariff refund supplied the entire gross margin gain, and by our math the new full-year plan still implies comparable growth slowing to about 3% in the fourth quarter.
| Comparable store sales | +7.2% +5.6% a year ago |
|---|---|
| Revenue | $5.12B +8.8% from a year ago |
| Gross margin (excluding $39M tariff refund) | 51.6% 52.4% reported (51.9% a year ago) |
| Full-year comparable sales outlook | Raised 1 pt new range: 5.5% to 6.5% |
⚖️ Verdict: 🟢 Bullish
The story got better because O'Reilly cleared the third-quarter tariff comparison with faster growth on both sides of the business, easing the main risk of a second-half stall. One caution: without the one-time tariff refund, gross margin slipped 0.2 percentage points from a year ago, while borrowing to fund share buybacks pushed interest costs up 37%.
The question now is whether the implied fourth-quarter slowdown to 3% comparable growth is just management's usual caution or the delayed bite of lapping last year's 6% price inflation. If repair shops are buying more parts, sales will beat the implied fourth-quarter rate just as they did in the third; if higher prices did the heavy lifting, growth will drop toward the plan. Fourth-quarter results in February will settle it.
🐂 Bull Case
Store Sales Accelerated Against Tougher Tariff Comparisons
Comparable store sales — revenue at U.S. stores open at least a year — had been expected to slow in the second half as O'Reilly lapped last year's tariff-driven price increases. Instead, comparable store sales grew 7.2% from a year ago, faster than the 6.0% pace in the second quarter.
Chief executive Brad Beckham said the growth was "driven by share gains on both sides of our business, with double-digit growth in our professional business and mid-single digit growth in DIY". Beckham raised the full-year comparable sales forecast by a full percentage point to 5.5% to 6.5%. Because the company beat its own second-half assumptions so handily, the standing concern about a sharp second-half slowdown has eased, even though the new full-year range still leaves fourth-quarter comparable growth at about 2.7% by our math.
What to watch: fourth-quarter comparable store sales when full-year results arrive in February. A reading above 2.7% would show that O'Reilly set its fourth-quarter plan with the same caution it used for the third quarter.
Professional Repair Shops Now Drive Over Half of Sales
O'Reilly sells auto parts to two groups: do-it-yourself (DIY) drivers who fix their own cars, and professional mechanics who run repair shops. Sales to professional shops grew 12.7% from a year ago to $2.60 billion, while DIY sales rose 6.2% to $2.45 billion.
Professional shops now bring in 50.8% of total revenue, up from 49.0% a year ago, extending a streak of double-digit growth to five straight quarters. DIY growth also stepped up from 4.9% in the second quarter, so both engines contributed to the quarter's revenue beat.
What to watch: professional revenue growth in the fourth quarter, when the comparison includes last year's peak tariff price increases. Holding near double digits would prove repair shops are buying more parts, not just paying higher prices.
Store Expansion Stays on Track Across North America
O'Reilly grows its footprint by opening new stores across the United States, Mexico and Canada. The retailer opened 63 net new stores in the third quarter, bringing its nine-month total to 173 across North America — 148 in the United States, 22 in Mexico and 3 in Canada.
Total store count reached 6,758, up 3.4% from a year ago, with the Mexican footprint expanding 25% to 134 stores. Beckham said the company remains "confident in the strength of the fundamental demand drivers in our business" and kept the full-year target at 225 to 235 openings.
What to watch: fourth-quarter openings against the 57 stores needed at the middle of the range, plus the initial 2027 store opening target in February. A higher 2027 target would show new distribution centres are unlocking more locations.
🐻 Bear Case
Tariff Refunds Provided the Entire Gross Margin Gain
O'Reilly reported a gross margin of 52.4% of sales, up 0.5 percentage points from 51.9% a year ago, as cost of goods sold — the cost of buying and distributing auto parts — fell as a share of sales. Operating margin rose 0.7 percentage points to 21.4%, helped by selling, general and administrative expenses (store payroll and overhead) dipping 0.2 points to 30.9% of sales.
However, Beckham noted the results were "coupled with a $39 million benefit from tariff refunds received during the third quarter". By our math, that one-time refund added 0.76 percentage points to margins; without it, gross margin fell 0.2 percentage points from a year ago to 51.6%, and operating margin was 20.7%. Beckham raised the full-year gross margin outlook by 0.1 percentage point, to 51.6% to 52.1%, to "incorporate our strong third quarter performance, including the benefit from tariff refunds, and our margin expectations for the fourth quarter". Because the $39 million refund equals 0.2 percentage points of full-year sales, raising the annual outlook by only 0.1 point means underlying fourth-quarter gross margin is slightly weaker than previously planned.
What to watch: fourth-quarter gross margin against the 52.0% rate implied by the full-year outlook. A result below 52.0% would confirm that faster growth in lower-margin professional sales is squeezing product margins once tariff refunds fade.
Debt-Funded Buybacks Push Borrowing and Interest Costs Up
O'Reilly uses cash flow and borrowed money to buy back its own shares, which boosts profit per share — diluted share count fell 4.8% from a year ago, turning an 8.2% net income gain into 14.1% earnings-per-share growth. The catch is that buybacks are outrunning cash generation and loading the balance sheet with debt.
- Nine-month share repurchases: $3.47 billion (38.5 million shares at $89.99), double the $1.73 billion of free cash flow
- Long-term debt: $7.71 billion, up 30.4% from $5.92 billion a year ago
- Adjusted debt to EBITDAR (debt plus leases relative to operating cash profit): 2.26 times, up from 2.17 in Q2 and 2.04 a year ago
- Third-quarter interest expense: $81.9 million, up 37.4% from a year ago
Higher interest bills and a slightly higher tax rate kept net income growth 5 percentage points below operating income growth of 12.5%. The company bought another $204 million of shares in October, leaving $727 million on its buyback authorisation.
What to watch: adjusted debt to EBITDAR at year-end against management's 2.5 times ceiling. As borrowing nears that limit, O'Reilly will have to slow buybacks toward its free cash flow pace.
Risks this quarter didn't answer
Five standing concerns and watch-list metrics are normally discussed on the conference call or in the quarterly filing, so the earnings release alone did not resolve them.
- DIY customer traffic: DIY sales rose 6.2%, but the release does not split out whether customer visits stayed negative while higher part prices carried the total.
- Consumer pressure from fuel prices and inflation: the release gives no commentary on whether drivers are still putting off larger repair jobs.
- Same-SKU price inflation: the release does not state how much of the 7.2% comparable store sales growth came from price increases on identical parts versus selling more items.
- Overhead cost per store: total overhead fell 0.2 percentage points as a share of sales, but per-store expense growth awaits the conference call.
- Acquisition plans: the release makes no mention of mergers or acquisitions following prior-quarter speculation about a rival.
💲 Other KPIs
The ratio of accounts payable to inventory — which measures how much of O'Reilly's parts stock is financed by suppliers rather than its own cash — slipped to 121.8% from 123.7% in the second quarter and 125.9% a year ago. Inventory grew 9.9% from a year ago to $6.17 billion, outpacing the 6.3% rise in payables and landing right on the ~122% year-end target.
Quarterly revenue per U.S. store rose 6.1% from a year ago to $764 thousand, stepping up from 5.0% growth in the second quarter ($733 thousand) and 4.5% a year ago. Over the last twelve months, sales per store reached $2.86 million, up 5.7% from $2.70 million in the prior year.
Third-quarter free cash flow — operating cash flow minus capital spending and share-based tax benefits — fell 15.2% from a year ago as operating cash flow dropped to $558.7 million from $616.5 million. For the first nine months, free cash flow is still up 44.0% to $1.73 billion because tax credit payments shifted between years.
🔮 Guidance
Raised. The middle of the range moved up 1.0 percentage point to 6.0% after third-quarter comparable sales grew 7.2%. With nine-month comparable sales at 7.1%, the updated plan leaves fourth-quarter growth at about 2.7% by our math, down from 5.6% in last year's fourth quarter. It is the second consecutive 1-point raise (+0.0 pts in Q1, +1.0 pt in Q2, +1.0 pt in Q3).
Raised. The auto parts retailer lifted both ends of the range by $100 million, putting the middle of the range at $19.15 billion, or 7.7% growth for the year. By our math, subtracting nine-month revenue of $14.57 billion leaves $4.58 billion for the fourth quarter, or 3.7% growth from a year ago against 8.8% in the third quarter. Moves by quarter: $0M, +$200M, +$100M.
Raised. Management lifted the full-year gross margin range by 0.1 percentage point to a middle of 51.85%, incorporating the $39 million third-quarter tariff refund. With nine-month gross margin at 51.8%, the plan implies about 52.0% in the fourth quarter by our math, down from 52.4% in the third quarter and up 0.2 points from 51.8% in last year's fourth quarter.
Raised. The full-year operating margin range moved up 0.2 percentage points to a middle of 19.75%. After a 20.1% margin across the first nine months, the full-year target implies an 18.7% operating margin for the fourth quarter by our math, seasonally lower than the third quarter's 21.4% and roughly matching the 18.8% recorded in the fourth quarter of 2025.
Raised. The expected full-year tax rate moved up 0.2 percentage points to 22.7%, after having been trimmed from 22.6% to 22.5% last quarter. The third-quarter effective tax rate was 23.1%, up from 21.4% a year ago, which modestly held back net income growth.
Raised. The range rose $0.05 to a middle of $3.30, or 11.1% full-year growth, and counts share buybacks only through October 28. Subtracting $2.54 earned in the first nine months leaves $0.76 for the fourth quarter by our math, up 7.0% from $0.71 a year ago. Third straight $0.05 raise (+$0.05 in Q1, +$0.05 in Q2, +$0.05 in Q3).
Raised. Operating cash flow moved up $100 million at both ends ($3,210 million to $3,620 million in the reconciliation table, middle $3,415 million, up 23.6% from 2025). With $2.60 billion generated in the first nine months, the outlook implies $817 million of operating cash flow in the fourth quarter by our math, compared with $633 million in the fourth quarter of 2025.
Unchanged. Capital spending on new stores and distribution centres remains planned at $1.35 billion at the middle of the range, up 15.5% from $1.17 billion in 2025. Because O'Reilly spent $860 million across the first nine months, reaching the middle of the full-year range requires $490 million of spending in the fourth quarter by our math, up from $308 million in the third quarter.
Raised. The free cash flow range rose $100 million to a middle of $2.05 billion, up 31.1% from $1.56 billion in 2025, flowing through the higher operating cash flow target. After $1.73 billion in the first nine months, the middle of the range leaves $320 million for the fourth quarter by our math, compared with $362 million in last year's fourth quarter.
Unchanged. The expansion plan holds at 230 net new stores at the middle of the range, up from 207 opened in 2025. Having opened 173 net new stores in the first nine months, the US company needs 57 openings in the fourth quarter by our math to hit the middle of the target, down slightly from 63 opened in the third quarter.
❓ Key Questions
How much did price inflation versus traffic drive comparable sales?
Comparable store sales accelerated to 7.2%, even though management previously expected same-item price inflation to cool to 2% in the third quarter. Knowing the exact price and ticket-count split will show whether repair volume genuinely sped up.
Are more tariff refunds included in the fourth-quarter margin plan?
A $39 million tariff refund added 0.76 percentage points to third-quarter gross margin, while the full-year gross margin target rose by only 0.1 point. Investors need to know whether any further refunds are baked into fourth-quarter expectations.
Did per-store overhead expenses slow down in the third quarter?
Total selling and administrative expenses grew 8.3% and dipped 0.2 percentage points as a share of sales, helped by the 7.2% comparable sales jump. If comparable growth slows toward the implied 2.7% in the fourth quarter, per-store cost growth must moderate to protect margins.
When will share buybacks slow to match free cash flow?
O'Reilly spent $3.47 billion on buybacks in nine months — double its $1.73 billion of free cash flow — pushing its leverage ratio to 2.26 times and lifting interest expense 37%. As leverage approaches the 2.5 times target, debt-funded buybacks have less room to run.
