President Trump’s new AI tirade hurting GOP?

AutoZone’s fiscal fourth quarter ended August 29, and the results landed before the open this morning. For the past week, the defining question was whether comparable-store sales would meet, miss, or fall well short of the Street’s target. UBS put its stake in the ground on September 15, forecasting domestic comps of just 2.5% against a Wall Street consensus clustered around 3.6%. That gap deserves a verdict.

Analyst Targets

• Oppenheimer: Outperform, target cut to $3,500 from $4,300 ahead of results
• Wells Fargo: Target lowered to $3,500 from $4,150
• Barclays: Target reduced to $3,637 from $3,900
• Citi: Buy, target trimmed to $3,450 from $3,700
• Consensus: Mean target near $3,887, implying roughly 36% upside from recent trading near $2,860

Company Profile

AutoZone is the largest specialty retailer of automotive replacement parts and accessories in the Americas, operating through two demand channels: DIY retail, where consumers buy and install their own parts, and commercial, where the company delivers to professional repair shops. As of Q3 FY2026, it ran 7,856 stores across the U.S., Mexico, and Brazil. Commercial sales carry higher volume and faster growth; DIY drives traffic and ticket frequency. Both channels matter for reading the health of the aftermarket industry.

The Numbers Going In

• Revenue consensus: About $6.71 billion
• EPS consensus: Roughly $54 per share
• Domestic comp consensus: About 3.7%; total constant-currency comp consensus: about 3.6%
• UBS below-consensus comp call: 2.5% domestic, citing soft aftermarket demand
• Q3 FY2026 actual domestic comp: 4.1%; commercial sales grew 10.4%, DIY grew 2.2%
• Q4 guidance from Q3 call: Comps expected similar to Q3; LIFO charge of $30 million projected
• DIY traffic trend in Q3: Negative 3.6% on transaction count

Why the Comp Is the Only Number That Matters Today

AutoZone’s Q3 showed exactly how the market has been grading this stock: an EPS beat of more than 5%, yet the stock fell roughly 9% on a revenue miss of less than half a percent. The market is not paying for profit efficiency right now. It is paying for demand health, specifically whether the DIY consumer is reengaging and whether commercial growth can hold double digits against increasingly tough comparisons.

UBS made the case that demand softened sharply during the June-to-August period corresponding to AutoZone’s fiscal Q4, with sales likely bottoming in June before a modest July-August acceleration. A 2.5% domestic comp versus the 3.6% consensus would confirm that the soft patch was real and sustained. Anything at or above the guide of roughly 3.9% would be a meaningful upside signal for a stock already down more than 13% year to date.

Commercial vs. DIY: The Split Investors Are Watching

Analysts expected commercial net sales of roughly $1.95 billion in Q4, implying about 10.6% year-over-year growth. DIY was expected to remain essentially flat. That divergence has been the defining feature of AutoZone’s recent quarters: professional shop demand is strong because aging vehicles require more complex repairs; retail self-service demand is soft because consumers are stretched and skipping discretionary maintenance. The LIFO charge, a $30 million non-cash accounting drag tied to elevated inventory costs, will compress reported gross margin regardless of volume, making the clean operating picture harder to read.

Forward Scenarios

Bull: Domestic comp at or above 3.9%, commercial growth above 10%, and management guidance for fiscal 2027 that signals mid-teens EPS growth. LIFO headwind shrinks in FY2027. Valuation re-rates from 18x toward the historical 23x-26x NTM P/E range.

Base: Comp prints between 2.8% and 3.4%, landing below guide but above UBS’s floor. Commercial holds, DIY traffic remains negative. Management frames the quarter as a trough and signals stabilization. Stock absorbs the miss without a major selloff.

Bear: Comp misses below 2.5%, DIY traffic deteriorates further, and gross margin compression from LIFO plus softer volume disappoints on the bottom line. FY2027 guidance disappoints. The stock’s one-year total return decline accelerates.

Technical Overlay

AZO was trading near $2,860 as of September 18, testing support at approximately $2,834. The stock has made a series of lower highs since the Q3 selloff from around $3,400. A comp beat would likely challenge resistance near $3,100; a miss risks a retest of multi-year lows below $2,800.

Bottom Line

The comp is the verdict on UBS’s miss call. But the more durable question is whether commercial momentum, now consistently in double digits, is sufficient to carry the stock through another quarter of DIY consumer softness. If the answer is yes, and management can credibly frame FY2027 earnings growth, the current valuation at 18x forward earnings looks like the opportunity. If DIY traffic fails to show any recovery and guidance disappoints, this stock’s discount deepens from here.
