O'Reilly (ORLY) Q4 2025 earnings review
33 Years of Growth: Comps Accelerate, But Costs Linger
O'Reilly capped 2025 with an impressive 5.6% comparable store sales growth in Q4, accelerating from earlier in the year and cementing its 33rd consecutive year of growth. The top-line momentum (+8% Revenue YoY) effectively masked continued inflationary pressures in SG&A, allowing operating margins to expand to 18.8%. Management remains aggressive, guiding for accelerated store openings in FY26 (225-235 units) and projecting another year of record revenue ($18.7B-$19.0B), proving the 'all-weather' nature of their aftermarket model.
🐂 Bull Case
Growth accelerated throughout FY25, exiting the year at +5.6% (vs +3.6% in Q1). This indicates market share gains are compounding, likely at the expense of independent competitors.
Management is pressing the accelerator on physical footprint, guiding for 225-235 net new stores in FY26, up from 207 in FY25. The new Virginia distribution center unlocks the lucrative mid-Atlantic region.
🐻 Bear Case
Despite sales leverage, management explicitly noted SG&A expenses 'again exceeded expectations' due to healthcare and casualty claim inflation. If sales growth moderates, these fixed cost pressures will bite margins hard.
While consistent, the forecasted FY26 revenue growth (~6%) and EPS growth (~6% at midpoint) reflects a mature compounder. The law of large numbers is making double-digit growth harder to achieve without aggressive buybacks.
⚖️ Verdict: 🟢🟢
Strong Buy. O'Reilly demonstrates textbook execution. Accelerating same-store sales in a mature industry combined with expanding margins (51.8% Gross) outweighs the SG&A inflation concerns. The aggressive store expansion guide signals management's high confidence.
Key Themes
Accelerating Physical Expansion
O'Reilly is shifting gears from steady growth to aggressive expansion. After opening 207 stores in FY25, the FY26 guidance targets 225-235 net new stores. This acceleration is supported by the new Virginia distribution center, which opens up the mid-Atlantic corridor—a 'last frontier' for the company.
Persistent SG&A Inflation
A recurring theme from FY25 Q3 and Q4. While SG&A as a percentage of sales improved slightly to 33.0% due to strong revenue leverage, the absolute dollar amount exceeded management's internal forecasts. The culprit remains 'heightened inflation in team member health care and casualty claim costs.' This operational friction is persistent and requires monitoring.
Gross Margin Strength
Gross margin expanded 50 basis points YoY to 51.8% in Q4, and 40 bps for the full year (51.6%). This confirms pricing power and supply chain efficiency. Guidance for FY26 suggests maintaining this high altitude (51.5%-52.0%), indicating tariffs and input costs are being successfully passed through.
Pro vs DIY Dynamics
While Q4 specifics weren't broken out in the text, prior quarters (Q2/Q3) highlighted the Professional (DIFM) segment growing significantly faster (+10% range) than DIY (low single digits). Management noted Q4 growth 'on both sides,' but the heavy lifting in comps (+5.6%) suggests the Professional segment continues to take significant share from fragmented competitors.
Macro/Tariff Uncertainty
Forward-looking statements explicitly list 'imposition of new or increased tariffs' as a risk. With ~25% of goods historically sourced from China (per Q3 calls), O'Reilly relies on industry-wide price rationality to pass these costs on. Any lag in pricing power could compress the projected 51.5%+ gross margins.
Other KPIs
Accelerating. Operating income grew 12% YoY, outpacing the 8% revenue growth. This demonstrates strong operating leverage despite the noted SG&A headwinds. Full year operating margin held steady at 19.5%.
Stable. Full year EPS grew 10%, driven by net income growth (+6%) and share repurchases (share count -3%). The 15-for-1 split in June 2025 resets the optical baseline for future comparisons.
Decelerating. FCF dropped from $1.99B in FY24 to $1.56B in FY25. This was driven by increased CapEx ($1.17B vs $1.02B) and inventory build ($604M cash use vs $404M prior year) to support the new distribution centers and store growth.
Guidance
Stable. Implies ~5-7% growth YoY, consistent with the 6% growth achieved in FY25. Assumes continued market share gains.
Decelerating. The midpoint (4.0%) represents a slight deceleration from the strong 4.7% achieved in FY25, likely factoring in difficult comps from the 25Q4 surge.
Decelerating. Implied growth is 4-8% YoY, slower than the 10% achieved in FY25. This likely reflects the continued SG&A pressure and a normalizing tax rate.
Accelerating. Forecasting a strong rebound from FY25's $1.56B, despite CapEx remaining elevated at $1.3-$1.4B. Suggests improved working capital management.
Key Questions
SG&A Persistence
SG&A exceeded expectations for multiple quarters due to insurance and healthcare costs. Is this a structural step-up in the cost base, or are these transient inflationary spikes that will normalize in 2026?
DIY vs Pro Divergence
With comps accelerating to 5.6%, what is the exact split between Professional and DIY? Are we seeing a recovery in the DIY consumer, or is the Pro segment carrying the entire load?
Tariff Pricing Power
Given the 2026 gross margin guidance remains strong (up to 52%), does this assume zero tariff impact, or does it assume fully successful pass-through of new tariffs to the consumer?
