The AutoZone Investment Case
AutoZone occupies a distinctive position in the spread analysis because it combines a well-rated credit (BBB / Baa2) with an operationally resilient business model. The company has increased earnings per share for 18 consecutive years through a combination of same-store sales growth, disciplined new store openings, and one of the most aggressive share repurchase programs in U.S. retail. This financial engineering is why the credit profile supports both bond issuance and long-term lease commitments simultaneously.
The auto parts sector is often described as the most internet-resistant corner of retail. Customers arrive with an immediate problem (a broken vehicle) and need a specific solution (a replacement part) that must be installed the same day. E-commerce alternatives require shipping times that are incompatible with a disabled vehicle. AutoZone’s store network of 6,300+ locations, combined with same-day hub delivery for less common parts, creates a physical infrastructure that no online competitor has replicated.
For bond investors evaluating this credit, the NNN comparison is straightforward: the same balance sheet that services AutoZone’s $8+ billion in outstanding bonds also guarantees 15-year absolute NNN leases. The NNN investor receives a higher yield because the real estate market demands a premium for small-format, purpose-built auto parts stores. The bond investor accepts a lower yield in exchange for daily liquidity. The credit risk is identical.
AutoZone vs. O’Reilly: Same Sector, Different Spreads
O’Reilly Auto Parts carries a BBB+ / Baa1 rating, one notch above AutoZone. This difference shows up in the bond market: O’Reilly bonds yield approximately 4.95% versus AutoZone’s 5.20%, a 25 basis point premium reflecting the rating gap. In the NNN market, both trade at nearly identical cap rates (5.75% to 6.75%) because the store formats, lease structures, and real estate characteristics are essentially the same. The result is that O’Reilly offers a slightly wider NNN spread (80 to 180 bps) than AutoZone (55 to 155 bps) because the bond starting point is lower while the NNN endpoint is the same.
For investors building a diversified auto parts NNN portfolio, holding both AutoZone and O’Reilly provides tenant diversification within a sector that shares the same structural resilience. The combined spread opportunity across both tenants ranges from 55 to 180 basis points.
As of Q1 2026, the nominal spread is approximately 55 to 155 basis points. AutoZone bonds yield roughly 5.20% while NNN properties trade at 5.75% to 6.75% cap rates. The after-tax spread is significantly wider because NNN income is sheltered by depreciation while bond interest is fully taxed.
AutoZone’s credit rating reflects its aggressive financial strategy. The company has repurchased over $40 billion in stock since 1998, funded substantially by debt issuance. This keeps leverage elevated relative to peers. S&P and Moody’s acknowledge AutoZone’s exceptional operating performance but balance it against the leveraged capital structure. For NNN investors, this means AutoZone bonds yield slightly more than higher-rated retailers, while the lease obligation is backed by the same operationally dominant business.
AutoZone is one of the most liquid NNN tenants in the market. The combination of a recognizable brand, investment grade credit, standardized building format, and price points in the $1.5M to $3.5M range makes AutoZone NNN accessible to a deep pool of individual, family office, and 1031 exchange buyers. Properties with 10+ years remaining typically sell within 60 to 90 days at or near asking price.
