AutoZone Inc. (AZO) shares dropped Wednesday morning after the auto parts retailer delivered fiscal first-quarter results that told two different stories: impressive sales growth paired with margin weakness that has investors hitting the brakes.

The Analyst Verdict

Two major firms adjusted their outlook on AutoZone while keeping faith in the long-term story. Guggenheim Securities analyst Steven Forbes maintained his Buy rating but trimmed the price target from $4,600 to $4,400. DA Davidson analyst Michael Baker followed suit, reiterating a Buy rating while cutting his target more aggressively from $4,850 to $4,500.

What's Working

Forbes called it a "solid start to 2026," pointing to continued momentum in the company's commercial business. Net sales climbed 8.3% year-over-year, powered by double-digit growth in domestic commercial sales. Management reported strength across all merchandise categories and boosted guidance for new store and hub store openings to 350-360 locations, up from the prior range of 335-350.

The revised guidance suggests average ticket trends could improve by around 100 basis points sequentially, "setting the stage for accelerated 2Q net sales growth," Forbes noted.

Baker highlighted that commercial sales jumped 14.5% in the quarter and stayed "relatively stable throughout the four-week periods." He believes the robust commercial performance signals AutoZone is taking share from competitors.

The Margin Problem

Here's where things get less exciting. AutoZone reported margins that missed expectations, and investors are worried about increased investments pressuring operating margins in the near term. Baker observed that DIY comparable sales remain weak compared to commercial, with failure and maintenance categories outperforming while discretionary products lag.

Shares of AutoZone were down 1.44% to $3,446.26 at the time of publication Wednesday.
