Overview
AutoZone, Inc. is a leading retailer and distributor of automotive replacement parts and accessories across the Americas. At Q3 FY2026, it operated 6,766 U.S. stores, 933 in Mexico and 157 in Brazil; FY2025 geography mix was about 88% U.S. and 12% outside the United States. The core advantage is a dense store footprint paired with hub/mega-hub and distribution-center inventory that improves parts availability for DIY customers and professional repair shops. Private-label brands, proprietary systems and favorable supplier terms add support, while risks include price competition, e-commerce, peers upgrading supply chains, tariff/inflation pressure and longer-term vehicle-mix shifts.
