AutoZone Inc (AZO) - Stock Report

The key macro issue is not repair-demand resilience in isolation, but whether that demand continues to pass through domestic same-store sales, gross margin and vendor-funded inventory into retained cash per share; if supplier financing or merchandise-cost pressure absorbs the growth, AutoZone can still report EPS progress while buyback capacity and valuation support become tighter.

The latest reported quarter is fiscal Q3 2026, the 12 weeks ended 9 May 2026, released on 26 May 2026 and followed by the fiscal Q3 2026 Form 10-Q published on 14 June 2026. On that 12-week, net sales rose 8.4% to $4.841bn, domestic same-store sales rose 4.1%, total same-store sales rose 5.5%, and reported diluted EPS rose 7.7% to $38.07. The quality check is mixed: gross margin for the quarter was 52.2%, down 57 bps because a 77 bp non-cash LIFO headwind offset other gross-margin improvements, while operating expenses improved to 33.1% of sales and reported operating profit rose 6.6% to $923.8m. Management guided only to approximately 355-365 global store openings for FY2026; it did not provide EPS or full-year financial guidance in the Q3 release.

The market snapshot uses the canonical $3,064.48 close on 18 June 2026. Q3 diluted weighted-average shares of 16.852m drive reported EPS and per-share operating math. Market-cap multiples use Market-data snapshot's exchange/market snapshot: about $52.41bn of equity value at the same close, an implied 17.102m market-cap share base, and a single operative EV anchor of about $61.17bn after the $8.76bn net-debt adjustment. The required post-buyback common-share view is a snapshot cross-check, not the multiples denominator: 16.325m shares outstanding at 5 June 2026 would imply about $50.03bn of equity value and $58.79bn of EV, while 16.369m shares outstanding at 9 May 2026 would imply about $50.16bn of equity value.

AutoZone sells replacement parts, maintenance items, accessories and related diagnostics content through 7,856 stores across the U.S., Mexico and Brazil as of 9 May 2026. The company reports one operating segment, but the economics are not one-dimensional: the U.S. DIY business is the high-margin availability engine, the domestic commercial program is the route-density growth engine, Mexico and Brazil extend the store runway with currency and execution friction, and ALLDATA adds a small software/service attachment to the installer relationship.

The store system is built around proximity and urgency rather than discretionary browsing. In Q3 FY2026, AutoZone had 6,766 U.S. stores, 933 Mexico stores and 157 Brazil stores; it opened 82 stores in the quarter and 199 net new stores over the first 36 weeks. Management's explicit operating plan is still physical expansion: approximately 355-365 global store openings for fiscal 2026, with commercial programs in 6,356 domestic stores.

Management is prioritizing market-share capture through store density, commercial delivery capability and inventory availability, not dividends. That is the right strategic posture for an urgent-parts retailer, but it raises the cash test: 10-Q capital expenditures were $997.5m in the first 36 weeks of FY2026 and $1.328bn in FY2025, so the company must prove that added stores and mega-hub capacity lift sales per store and route density enough to protect the post-capex cash proxy.
