AutoZone is the leading retailer and distributor of automotive replacement parts, maintenance items, and accessories across North America, serving both do-it-yourself consumers through retail stores and e-commerce as well as commercial customers including repair garages, dealers, and fleet operators through dedicated commercial channels. The company generates revenue through transactional retail and wholesale distribution of hard parts and accessories for cars and light-duty trucks, with commercial sales representing a growing, higher-margin portion of its business, while also operating ALLDATA, a provider of automotive diagnostic and shop management software. AutoZone's long-term demand drivers rest on vehicle aging, miles driven, and the maintenance and replacement needs of the vehicle fleet, positioning it in the durable aftermarket repair and maintenance market rather than new vehicle parts.
