AutoZone (AZO) Q2 2026 earnings review
Top-Line Growth Obscured by Squeezed Profits and Plunging Cash Flow
AutoZone delivered strong top-line revenue growth of 8.1% in Q2, but the underlying narrative is more complicated. A massive 138-basis-point non-cash LIFO accounting charge crushed gross margins, causing Operating Profit and Net Income to decline year-over-year. While the Domestic Commercial business continues to be a reliable growth engine, overall constant-currency Same Store Sales (SSS) decelerated to 3.3%. An alarming 41% drop in Operating Cash Flow and a sharp slowdown in the International segment add significant friction to the bullish store-expansion story.
🐂 Bull Case
The Domestic Commercial business posted 9.8% YoY growth. AutoZone continues to steal market share in this massive segment through improved inventory availability and faster delivery.
The company opened 64 net new stores globally this quarter and remains on track to hit its aggressive target of 350-360 new stores for the full fiscal year.
🐻 Bear Case
Constant-currency International Same Store Sales decelerated drastically to 2.5%, down from 9.5% in the same period last year, raising questions about execution in key growth markets like Mexico and Brazil.
Operating Cash Flow collapsed 41% year-over-year to $342M. Combined with a 13.1% rise in inventory and declining net income, the company is spending heavily for diminishing near-term returns.
⚖️ Verdict: 🔴
Bearish-leaning Neutral. While AutoZone's sales growth initiatives are clearly working, the cost to achieve that growth is mounting. Plunging cash flows, severe LIFO-driven margin compression, and an unexpected slowdown in International SSS make this a tough quarter to cheer.
Key Themes
LIFO Charge Crushes Gross Margins
AutoZone's gross margin fell a steep 137 basis points to 52.5%. Management attributed 138 basis points of this drop entirely to a non-cash LIFO charge (an accounting method that reflects higher recent inventory costs). Stripping this out, underlying merchandise margins were essentially flat, but the severe accounting impact dragged Operating Profit down 1.2% year-over-year.
International Growth Hits a Wall
Decelerating. A major red flag emerged in the International segment. While reported SSS jumped 17.1% due to massive foreign exchange fluctuations, the true operational metric—Constant Currency SSS—collapsed to 2.5%. This is a severe deceleration from 9.5% a year ago and 8.1% in Q3 2025, suggesting underlying demand in Mexico and Brazil is softening significantly.
Domestic Commercial Continues to Outpace DIY
Stable. The Domestic Commercial (B2B) segment grew 9.8% YoY, generating $1.15B. While this is a deceleration from Q1's blistering 14.5% pace, it strongly outpaces the overall Domestic SSS of 3.4%. Average weekly sales per program increased 4.8% to $15,400. AutoZone's investments in Mega Hubs and delivery speed continue to win market share from local garages and fleet owners.
SG&A Deleverage Due to Store Build-out
Decelerating profitability. Operating expenses as a percentage of sales rose to 36.1% from 36.0% last year. Management explicitly tied this to investments supporting growth initiatives. Opening 64 new stores in a single quarter requires significant upfront capital and staffing expenses before those locations reach maturity.
Weather Disruptions in Mid-Winter
Management noted that winter storms caused disruptions in the last week of January and the first week of February. While AutoZone typically benefits from harsh weather later in the year (as potholes and salt wear down vehicle parts), immediate severe weather often suppresses foot traffic in the short term.
Other KPIs
Reversing. Cash flow from operations collapsed 41.3% from $583.7M in the same quarter last year. When compared against capital spending of $327.5M, Free Cash Flow for the quarter was virtually wiped out (down to just $15M from $291M last year). This warrants heavy scrutiny.
Accelerating. Inventory levels surged 13.1% YoY. Management pointed to growth initiatives (new store stocking) and inflation as the primary drivers. Net inventory per store improved slightly to negative $105K from negative $161K last year, meaning accounts payable are funding slightly less of the inventory burden than they did previously.
Stable. The company bought back 85,000 shares at an average price of $3,666. AutoZone still has $1.39 billion remaining under its current authorization, providing a persistent floor for the stock.
Guidance
Accelerating. Management reiterated their target for full-year store openings. This represents a significant step up from the 304 net new stores opened in FY25, highlighting the company's aggressive, capital-intensive strategy to capture market share.
Key Questions
International Slowdown
Constant currency International SSS decelerated sharply to 2.5% this quarter, down from 9.5% a year ago. What specific macroeconomic or competitive factors are driving this sudden softness in Mexico and Brazil?
Cash Flow Collapse
Operating Cash Flow dropped over 40% year-over-year in Q2. Can you break down the working capital dynamics—specifically inventory build versus accounts payable timing—that drove this severe cash squeeze?
LIFO Peak and Reversal
The 138-basis-point LIFO charge completely erased your gross margin stability. Given your supply chain visibility, when do you expect these inflationary cost pressures to peak, and when might we see LIFO credits flow back into earnings?
