AutoZone (AZO) Q4 2026 Earnings Call Transcript

AutoZone reported fiscal Q4 sales of $6.6 billion, up 5.6%, and diluted EPS of $56.05, up 15.1%; excluding year-over-year LIFO differences, EBIT and EPS grew 4.4% and 8.5%, respectively. Domestic commercial sales rose 8.6% to $1.9 billion, offsetting a 0.6% decline in DIY comparable sales as roughly 5% ticket inflation was offset by weaker customer traffic. Gross margin expanded 182bps to 53.3%, aided by a $96 million IEEPA tariff refund worth $4.43 per share, while AutoZone opened a record 374 stores in FY2026 and repurchased $2.0 billion of stock. For FY2027, management expects domestic comps to be flat to low-single-digit positive, commercial sales growth in the high-single to low-double digits, about 400 new stores, and approximately $1.65 billion in capex.

Analysis

AZO's investable issue is not the reported EPS beat but the quality of the forward earnings base: non-recurring tariff recovery, FX translation, and unusually low inventory-accounting expense flattered the quarter while the core consumer transaction trend remains weak. The market will likely focus on whether commercial share gains can offset an inflation-driven volume decline; commercial mix is structurally margin-accretive only after the hub/store cohort matures, while near-term new-unit labor, rent, and inventory create operating deleverage. This creates a 1-3 month valuation risk if FY27 consensus embeds a clean return to mid-single-digit comp growth before traffic actually improves.

The strategic winner is AZO versus smaller regional distributors and independent jobbers: denser hub coverage reduces professional-shop downtime, raising switching costs and permitting share capture from fragmented suppliers. O'Reilly Automotive (ORLY) is the most relevant public read-through and likely the cleaner near-term beneficiary if it is executing similar availability gains with less incremental capital intensity; Advance Auto Parts (AAP) remains vulnerable where delivery speed and local assortment determine account retention. A sustained higher fuel/freight environment is mixed: it supports ticket growth and replacement-part pricing but taxes the lower-income DIY customer first, favoring commercial/DIFM mix over retail.

Contrarian view: the market may over-penalize the declining reported ROIC during an intentionally front-loaded network build. If mature-store commercial sales compound as planned, the fixed cost of the hub network can drive a delayed margin inflection over 6-18 months. That thesis is falsified if domestic commercial growth falls below high-single digits for two quarters, SG&A growth remains above sales growth despite moderating investment spend, or new-store cohorts fail to show the expected second-year sales ramp.

Key Decisions for Investors

• Maintain a neutral-to-underweight AZO stance into the next print; avoid chasing an earnings-driven move until underlying domestic transactions stabilize. Reassess long exposure only if commercial growth remains at least 8% and DIY traffic improves sequentially, with a 6-12 month target based on evidence of SG&A leverage rather than tariff-adjusted EPS.
• Express the competitive thesis as long ORLY / short AAP over 3-6 months. Both benefit from aging vehicles and professional repair demand, but AAP has greater execution and account-retention risk if service-level competition intensifies; cover the short if AAP demonstrates sustained commercial comp outperformance or material margin recovery.
• Use AZO versus ORLY as a relative-value monitor rather than an immediate pair trade: go long AZO / short ORLY only after two consecutive quarters of commercial growth outperformance and evidence that hub-linked sales lift is translating into EBIT leverage. Missing data: current relative valuation, borrow cost, and consensus FY27-FY28 EBIT revisions.
• Set an alert around fuel-price and consumer-stress indicators over the next 1-3 months. Rising gasoline prices paired with deteriorating retail-sales data would reinforce short-term DIY downside and favor commercial-heavy aftermarket exposure; a sharp decline in fuel costs or improving consumer confidence would invalidate that mix-shift thesis.
