AutoZone delivered fiscal fourth-quarter earnings of $56.05 per share on revenue of $6.595 billion, topping the $54.54 consensus and the $54.26 Earnings Whisper by 3.3%, with earnings growing 15.1% year over year. But revenue missed the $6.71 billion consensus by 1.7% and grew just 5.6% — a sharp step down from the roughly 8% pace the company had held all year (+8.4% in Q3, +8.1% in Q2, +8.2% in Q1). That gap between a solid EPS beat and a clear top-line deceleration is the central tension of the quarter, and the composition of the beat makes it more pronounced, not less.
Gross margin of 53.3% expanded 182 basis points, but management attributed 145 basis points to tariff refunds and 105 basis points to a net non-cash LIFO benefit — roughly 250 basis points of the improvement from items that are not core operating performance. The IEPA tariff refund alone was $96 million, or $4.43 per share. Strip that out and the profit picture looks materially different: operating expenses deleveraged 101 basis points to 33.4% of sales, after leveraging 25 basis points in the third quarter, and commercial mix pressured gross margin. For the full year, the underlying math is more sobering — sales rose 7.4% to $20.3 billion, but operating profit grew only 3.1%, net income 3.0%, and diluted EPS 5.3% to $152.55, with share repurchases of $2.0 billion doing much of that per-share work. Adjusted after-tax ROIC fell to 35.8% from 41.3%.
Beneath the headline, the demand signal is what matters. Domestic DIY comparable sales turned negative at -0.6%, versus +2.2% in Q3 and +1.5% in each of the prior two quarters, with transactions down more than 5% as financially stretched consumers defer repairs and trade down against roughly 9% two-year ticket inflation. Total domestic comps slowed to +1.6% from +4.1% in Q3. Commercial remains the strongest part of the business — up 8.6% in the quarter and roughly 11% for the year, with per-program weekly sales of $18,700 — but even that line decelerated from +14.5% in Q1. International optics of +10.7% collapse to +1.3% in constant currency on continued Mexican macro softness. Nearly every growth vector slowed simultaneously.
Management's counterargument is timing. CEO Phil Daniele acknowledged a difficult selling environment in the first eight weeks of the quarter and said results strengthened over the back eight weeks, with domestic comps cited at +2.1% in August and international expected to inflect to low-single-digit growth in the first quarter. He expects sales in all three countries to accelerate in fiscal 2027. The infrastructure supporting that claim is real: 175 new stores in the quarter including 16 mega hubs, a record 374 openings for the year with roughly 400 planned for FY27, mega hubs at 172 versus 137 in Q1 against a ~300 target, the relocated and now-operational Monterrey DC, and free cash flow of $684 million in the quarter versus $511 million a year ago despite heavier capex. Programs tied to a mega hub reportedly sell 16% more than the balance of the chain.
The forward-looking negatives deserve equal weight. The FY28 store target was cut from roughly 500 to about 430 as Brazil expansion is slowed, growth initiatives continue to drive SG&A deleverage and 10.1% inventory growth, higher oil prices are lifting freight costs, and management flagged near-term ROIC pressure in the mid-30s from accelerated store growth. This is a company spending heavily into a soft consumer and asking investors to underwrite a second-half inflection.
The market was already skeptical. Shares entered the print at $2,803, down 12.8% since the opening price after the prior report, 15.9% below the 200-day moving average, 13.5% off the inter-earnings high of $3,239, and fractionally above a 52-week low of $2,796.85 set the day before earnings. Earnings Whispers investor sentiment swung from +0.20 to -0.23 — a meaningful shift from modestly positive to negative. Price and AVWAP trends remain negative even as momentum and life-cycle readings hold positive, a genuinely split picture that mirrors the fundamentals.
The bottom line is that AutoZone beat on EPS with substantial help from tariff refunds and a LIFO swing while missing on revenue and posting its weakest comp quarter of the year, with DIY outright negative. The commercial business, mega hub build-out, record store growth, and improving free cash flow keep a credible multi-year story intact, and August's stronger exit rate supports management's acceleration thesis. But with the stock at 52-week lows, sentiment turning negative, and the quality of the margin expansion open to question, investors are being asked to pay for an inflection that has not yet shown up in the reported comps.
