AZO vs LKQ: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of October 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

Reading it: LKQ is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. AZO and LKQ share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined AZO and LKQ exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

AutoZone is the largest retailer and distributor of automotive replacement parts and accessories in the United States, with about 8,000 locations across the US, Mexico, and Brazil. It sells hard parts, maintenance items, tools, and accessories to both do-it-yourself (DIY) retail customers and, increasingly, to professional repair shops through its commercial (do-it-for-me, or DIFM) program. Demand is relatively defensive because people keep older cars on the road longer during uncertain economies, and parts eventually fail regardless of the cycle.

It operates primarily through its Wholesale North America and Europe segments plus a Specialty segment, serving body shops, mechanical repair shops and retail customers, and its scale in salvage and aftermarket sourcing is its core competitive moat.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• AZO drivers: Professional (DIFM) expansion; Aggressive share buybacks.
• LKQ drivers: Structural demand for alternative parts; Portfolio simplification and strategic review.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: AutoZone's DIY comparable sales grow only in the low single digits and DIY customer traffic has at times declined, a pressure analysts flagged again after the fiscal fourth quarter of 2026, so much of the per-share growth depends on buybacks rather than underlying volume. For LKQ, lKQ's revenue is tied to accident frequency, collision-claim volumes and miles driven, all of which have been soft, pressuring organic growth and margins.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick AZO if you believe its drivers more; LKQ if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the AZO and LKQ guides.

AZO. As of October 2026, AutoZone traded at about 20.5 times trailing earnings and about 16 times forward earnings, with a market cap near $51 billion, a lower multiple than the mid-20s it carried in mid-2026 after the stock fell about 22% over the past year. Fiscal fourth-quarter 2026 EPS of about $56 beat estimates, but revenue missed slightly and analysts pointed to DIY pressure. Gross margin runs near 52% and operating margin near 20%, and the next report, for the first quarter of fiscal 2027, is expected around early December with consensus EPS near $35.

LKQ. At about $22.48 on October 16, 2026, LKQ trades near 12.6x trailing and 7.3x forward earnings, about 0.4x sales and below book value, the multiple of a mature distributor with shrinking revenue rather than a grower. Enterprise value is roughly $10.7 billion once about $5 billion of net debt is added, around 7.6x EBITDA. The low multiple and a dividend yield near 5.4% are central to the value framing, and the October 29 third-quarter report (consensus about $0.70 EPS on $3.41 billion revenue) will show whether estimates have stopped falling.

Headline figures (approximate, October 2026): AZO shows revenue (fy2026) ~$20.3B (Q4 up ~5.6% YoY), q4 fy2026 net sales (16 weeks) ~$6.59B, q4 fy2026 eps ~$56.05 (vs ~$53.89 est.), net income (fy2026) ~$2.57B (~12.7% margin); LKQ shows revenue (ttm) ~$13.7B, q2 2026 revenue ~$3.41B (down ~3% YoY), q2 2026 adjusted eps $0.67 vs ~$0.71 est., net income (ttm) ~$464M (~3.4% margin).

AZO and LKQ are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.
