O'Reilly Automotive Outpaces S&P 500 Through Disciplined Expansion and Buybacks

O'Reilly Automotive (ORLY) has emerged as a significant market outperformer, demonstrating that consistent growth can be achieved outside the high-growth technology sector. Since late April 2021, the aftermarket auto parts retailer has seen its total return climb 162%, nearly doubling the S&P 500's 84% return over the same period. The company's business model relies on the essential nature of vehicle maintenance. With the average age of U.S. vehicles rising and annual mileage increasing, demand for parts remains stable regardless of broader economic cycles. This durability is reflected in O'Reilly's 33-year streak of consecutive same-store sales growth and record revenue. As of December 31, 2025, O'Reilly operated 6,447 stores across the U.S., Mexico, and Canada. The company added 207 net new locations in 2025 and plans to open between 225 and 235 more in 2026. This expansion has consistently boosted the top line, while net income rose 173% over the last decade. A key driver of shareholder value has been the company's disciplined capital allocation. Diluted earnings per share grew 386% over ten years, bolstered by a 44% reduction in outstanding shares between 2015 and 2025. While the current price-to-earnings ratio of 31.4 suggests a premium valuation, the stock is currently trading 14% below its all-time high.
