AutoZone Posts Steepest Drop in Over Four Years Despite Earnings Beat, as Growth Concerns Mount

AutoZone Inc. suffered its worst trading day in more than four years on Tuesday, closing 9% lower despite reporting third-quarter fiscal results that exceeded Wall Street estimates. The stock fell 9%, its steepest decline since a 9.5% drop on May 18, 2022, and continued to slide in after-hours trading.

Earnings Beat Fails to Calm Investor Skepticism

For the fiscal quarter ended May 9, the Memphis-based auto parts retailer reported earnings per share of $38.07, surpassing the average analyst estimate of $36.28 compiled by LSEG. Revenue came in at $4.84 billion, largely in line with the $4.83 billion consensus forecast. Despite the headline beat, analysts on the company’s quarterly earnings call flagged concerns over sluggish international growth and margin compression that increasingly mirrors competitors. They also pressed executives on a year-over-year sales slowdown, which management attributed to unseasonably cool weather.

“This slowdown in sales was caused by unseasonably cool weather impacting our heat-related categories, which normally begin to ramp this time of year as summer heat begins to take hold,” Chief Executive Philip Daniele said on Tuesday.

Inflation, Energy Costs, and Motor Oil Supply Risks Under Scrutiny

Wall Street analysts also questioned AutoZone executives about persistent pressures from inflation, rising energy costs, and potential supply chain disruptions linked to the Iran war, particularly possible shortages of motor oil. Management said they expect inflationary pressures to continue but be “slightly muted” due to year-over-year comparisons. Regarding lubricant supply concerns that have reportedly affected dealer operations at Toyota Motor Corp. and Nissan Motor Co., executives expressed limited alarm.

“The issue around lubricants, I know there’s a lot of noise out there. We’re going to leave that up to the oil specialists to really say what that means. We think there’s probably going to be some constraints, but we don’t think that it’s going to be that material,” Daniele said.

Automotive website The Drive reported that both Nissan and Toyota have recently issued service bulletins to dealers instructing them to ration motor oil stocks due to an impending shortage. A Toyota spokesman said the company has “nothing more to add on this issue at this time.” A Nissan spokeswoman stated that the automaker “is navigating supplier constraints affecting lubricant availability.”

“Currently, we are maintaining current pricing and have implemented temporary allocation measures to help ensure consistent supply across our dealer network. We’re also working with supplier partners to identify additional sourcing. Our priority remains supporting our dealers to ensure an exceptional customer experience,” the Nissan spokeswoman said in an emailed statement.
