Is AutoZone Stock Ready For A Year Of Flat Store Sales?

Investors in AutoZone (AZO) share a worry that has only partly come true: people who fix their own cars keep cutting back until store sales stop growing. Overall domestic same-store sales still grew 1.6% in the latest quarter. On its September 22, 2026, call, management said it sees those shoppers putting off repairs and trading down. Shareholders have already lived through a hard year, with the stock losing 22.7% over the past year against a 17.4% gain for the S&P 500. So how close is AutoZone to a year of flat store sales already?

How Close Is AutoZone To Flat Store Sales?

AutoZone is already part of the way there. Domestic same-store sales to do-it-yourself customers fell 0.6% in the fiscal fourth quarter of 2026, while domestic commercial sales grew 8.6%. Management said the average do-it-yourself ticket rose roughly 5%, but fewer transactions offset that increase, with the most financially challenged customers deferring repairs and trading down.

For the first quarter of fiscal 2027, management expects same-store sales to be relatively flat. It expects domestic same-store sales to be flat to up low single digits for the full year, so the bottom of AutoZone’s own guide is a year of flat store sales.

What Flat Store Sales Would Cost AutoZone

The margin would be the first place flat sales show up, since management expects selling, general and administrative costs per store to rise roughly 4% in the first quarter of fiscal 2027. Operating margin was 20.7% in the twelve months to May 2024 and 19.6% a year later. It slipped again to 18.0% in the twelve months to May 9, 2026.

The bigger cost would fall on the buyback. Management plans to invest around $1.65 billion in fiscal 2027, mostly in new stores. If cash from operations stayed at the $3.07 billion of the twelve months to May 9, 2026, that would leave about $1.42 billion of free cash flow. That base predates the fourth quarter, and management said free cash reached roughly $1.8 billion for the full year. AutoZone’s $2 billion buyback in fiscal 2026 already topped the roughly $1.8 billion of free cash management said it made that year. On flat sales, free cash would fall further below a buyback that size.

What AutoZone Already Has Against A Slowdown

AutoZone stock fell less than the S&P 500 in three of four recent market shocks. It fell 13.0% at its worst during the 2022 inflation shock and Fed tightening, against 24.0% for the S&P 500.

The company’s interest bill is well covered: operating income was 7.5 times interest expense in the twelve months to May 9, 2026. The commercial business provides a larger cushion. Management said domestic commercial sales were just under $5.8 billion in fiscal 2026 and grew just under 11%. It expects them to grow high single to low double digits in fiscal 2027, so AutoZone would still have a growing business if do-it-yourself sales stood still.

When AutoZone Will Show Whether Store Sales Stall

AutoZone’s next report covers the quarter management guided for relatively flat same-store sales. Management also plans to open about 400 stores in fiscal 2027, against 374 in fiscal 2026, so AutoZone keeps adding stores whatever happens at existing ones. Domestic do-it-yourself same-store sales are the number to watch when AutoZone next reports, expected in early December, 2026.
