AutoZone reported a solid Q3 2025, underscoring sustained momentum in domestic commercial (DIFM) and international markets, while sustaining growth through aggressive store network expansion and hub-based fulfillment. Total sales rose 5.4% to $4.46 billion, led by a 10.7% year-over-year increase in domestic DIFM, and an 8.1% constant-currency international comp. Domestic DIY growth remained resilient with a 3% comp, supported by a 1.4% rise in DIY traffic and modest 1% ticket inflation. However, FX headwinds and higher DC ramp costs pressured margins, with gross margin at 52.7% (down ~77 bp YoY) and EBIT down 3.8% YoY, partly offset by a $16 million LIFO credit and ongoing mix shifts toward higher-margin commercial activity. Diluted EPS reached $35.36, down 3.6% YoY, largely due to a roughly $1.10 per share impact from Mexico FX. The quarter also featured meaningful capital allocation activity, including the repurchase of $250 million of AutoZone stock and continued investment in CapEx (~$1.3 billion for the year) to accelerate Hub/MegaHub growth, satellite store expansion, and international store openings. Management remains confident in sustaining top-line momentum into Q4 and beyond, while acknowledging near-term margin headwinds from DC ramp, shrink, and tariff dynamics. The company emphasized disciplined SG&A investment aligned with growth initiatives and a long-run plan to gain market share across domestic and international markets.
