Founded in 1979 as Auto Shack by Pitt Hyde in Memphis, the company sells replacement parts to do-it-yourself customers and increasingly to professional repair shops. Its distinguishing financial characteristic is capital allocation: for more than two decades it has bought back a very large share of its own stock, shrinking the count dramatically while operating with negative book equity. Demand rises as vehicle fleets age, giving results a defensive tilt. Headquarters remain in Memphis, Tennessee.

Equity comp at AutoZone
- RSUs use single-trigger vesting: shares become yours as each portion vests on schedule, and the value is taxed as ordinary income at that point. No IPO or acquisition is required.

AutoZone equity questions
- How much AZO stock is too much?
- There is no single threshold, but the larger the share of your net worth in one stock, the more a single bad year can set back your plans. The calculator above quantifies the drawdown impact at 30, 50, and 70 percent for your AZO position and weighs selling down (which triggers capital-gains tax now) against hedging (which costs option premium).
- Does AutoZone grant ISOs, NSOs, or RSUs?
- Equity compensation at AutoZone typically takes the form of restricted stock units (RSUs). Restricted stock units are taxed as ordinary income when they vest.
- Do AutoZone RSUs use double-trigger vesting?
- No. AutoZone restricted stock units (RSUs) use single-trigger vesting: each tranche becomes yours as it vests on schedule, taxed as ordinary income at that point, with no liquidity event required.
