AutoZone (AZO) is back in focus after its Q3 2026 report showed higher sales, net income and earnings per share versus a year ago, along with fresh supply chain investments and new mega hub openings.

AutoZone's share price has been under pressure, with a 30 day share price return down 10.86% and a 90 day share price return down 15.15%. However, recent Q3 results, capital spending and buybacks have kept longer term total shareholder returns positive over 3 and 5 years.

If AutoZone's recent moves have you reassessing opportunities in retail and automation, this could be a good time to scan the market for 33 robotics and automation stocks.

So with the stock down over the past year but trading at a roughly 16% discount to an estimated intrinsic value and about 26% below analyst price targets, is AutoZone now undervalued, or is the market already pricing in future growth?

Price-to-Earnings of 20.6x: Is it justified?

On simple earnings terms, AutoZone trades on a P/E of 20.6x, which sits slightly below its peer group but a touch above the broader US specialty retail industry.

The P/E multiple compares the current share price with earnings per share, so it effectively reflects what investors are currently willing to pay for each dollar of AutoZone's earnings. For a business focused on auto parts retail and distribution, this ratio helps you weigh current profitability against expectations for future profit growth.

AutoZone's P/E of 20.6x is described as good value versus its direct peers at 23.1x, which hints that the stock is priced more conservatively than similar companies. However, compared with the wider US specialty retail industry at 20.3x, and an estimated fair P/E of 20.4x, the valuation looks only marginally richer than what a broad market or model driven view might suggest as a steady state level.

Result: Price-to-Earnings of 20.6x (ABOUT RIGHT)

However, there are still clear pressure points, including the share price decline over the past year and any shift in demand for automotive parts across its core markets.

Another View: Cash Flows Point To More Upside

While the P/E of 20.6x suggests AutoZone is priced roughly in line with a fair ratio, the SWS DCF model presents a different perspective. On that view, the stock at $3,116.43 is trading about 15.6% below an estimated future cash flow value of $3,691.69. This raises a key question: are earnings multiples missing part of the picture?
