Executive TL;DR
AutoZone (AZO) just closed fiscal 2026 with record annual sales of $20.34 billion, its first year ever above the $20 billion mark, alongside fourth-quarter diluted EPS of $56.05.
The stock has still dropped ~14% year-to-date even after a post-earnings pop, badly trailing the broader market.
Commercial (do-it-for-me) sales, Mega Hub expansion, and buybacks remain the core growth engine, while the domestic DIY business stays soft and gross margin quality is muddied by tariff-driven LIFO charges.
The balance sheet carries negative shareholders’ equity and roughly $9 billion in debt, a structural feature of AutoZone’s model that amplifies both the upside and the risk.
Fiscal 2027 guidance points to modest domestic comparable sales growth and continued store and Mega Hub expansion, with Wall Street price targets clustered well above the current share price.

AutoZone runs like a machine that has now produced 36 consecutive years of record sales, and yet its stock has spent most of 2026 sliding while that streak extended.
Fourth-quarter results beat earnings estimates comfortably, tariff refunds padded the top line, and management guided to hundreds more store openings in fiscal 2027. At the same time, the shares are down, gross margin quality is under scrutiny, and the company’s debt load remains far heavier than any of its direct peers.
For investors, AutoZone sits in an unusual pocket of the market right now: a domestically-focused, dollar-denominated retailer with almost no direct exposure to overseas currency swings outside of Mexico and Brazil, yet one whose near-term earnings are unusually tangled up in US trade and tariff policy.
This deep-dive analysis breaks down everything so that you can make the right move on AZO.
AutoZone Company Profile: Key Facts Snapshot
Ticker: AZO (NYSE)
Headquarters: Memphis, Tennessee
Founded: 1979
CEO: Philip Daniele
Fiscal year end: Last Saturday in August
FY2026 net sales: $20.34 billion
FY2026 store count: 8,031+ (domestic, Mexico, Brazil combined)
FY2026 Mega Hubs: 172
Primary segments: Domestic DIY, Domestic Commercial, International (Mexico & Brazil)
Key brands: Duralast, ALLDATA
AutoZone sells automotive replacement parts, maintenance items, and accessories to two very different buyers:
Everyday car owners fixing their own vehicles (DIY) and
Repair shops that need same-day parts delivery (commercial, sometimes called “do-it-for-me”).
The company also owns ALLDATA, a diagnostic and repair-information software business sold through alldata.com, and its private-label Duralast parts line, which now spans everything from brakes to batteries.
AutoZone ended fiscal 2026 with 1,001 stores in Mexico and 167 in Brazil, for 1,168 international locations layered on top of its US footprint.
The company crossed a symbolic milestone during the year as well, celebrating the opening of its 8,000th store globally, a marker of just how far the chain has expanded from its single-store beginnings in Forrest City, Arkansas in 1979.
Philip Daniele has served as CEO through much of this recent expansion phase, overseeing the shift toward commercial growth and Mega Hub density that now defines the company’s strategy.
AutoZone Investment Thesis
The core bet
AutoZone is a scale operator in a defensive, need-based category.
Cars keep aging, average vehicle age in the US now sits near 12.8 years according to the company’s own regulatory filings, and older cars need more parts. Management is pressing that advantage through commercial market share gains, Mega Hub density, and relentless buybacks that shrink the share count year after year.
The question now is whether the price being paid for that business model, and the leverage being used to fund it, still make sense after a stretch of margin pressure and a soft DIY segment.
