Business Description

Nature of Business: O’Reilly Automotive, Inc. and Subsidiaries, collectively, “O’Reilly” or the “Company,” is a specialty retailer and supplier of automotive aftermarket parts. The Company’s stores carry an extensive product line, including new and remanufactured automotive hard parts, maintenance items, and various automotive accessories. As of December 31, 2025, the Company owned and operated 6,585 stores in 48 U.S. states, Puerto Rico, Mexico, and Canada, servicing both do-it-yourself (“DIY”) and professional service provider customers. The Company’s robust distribution system provides stores with same-day or overnight access to an extensive inventory of hard-to-find items not typically stocked in the stores of other auto parts retailers. ​ In May 2025, the number of shares of the Company’s authorized common stock was increased to 1.25 billion shares in order to implement a 15-for-1 forward stock split of its common stock, which was completed on June 10, 2025. All share and per share information, including share-based compensation, in the current and comparable periods throughout this annual report on Form 10-K, has been retrospectively adjusted to reflect the stock split. All shares of common stock retained a par value of $0.01 per share. Accordingly, an amount equal to the par value of the increased shares resulting from the stock split was reclassified from “Additional paid-in capital” to “Common stock.”
