O’Reilly Auto Parts is the strongest-rated auto parts retailer in the NNN market and one of the most compelling bond-to-NNN spread opportunities in the BBB+ tier. The same BBB+ / Baa1 credit that prices an O’Reilly senior unsecured bond also backs the lease on every O’Reilly NNN property. The NNN investor earns 80 to 180 basis points more nominal yield, plus the tax advantages that fixed income investors cannot access.

Why Auto Parts Offers a Compelling Spread
The auto parts sector occupies a unique position in the spread analysis. O’Reilly carries a BBB+ / Baa1 rating, which is one notch higher than the BBB index average. Its bonds price tighter than the index benchmark, yielding approximately 4.95%. Yet its NNN properties trade at 5.75% to 6.75% cap rates, delivering a meaningful spread that would not exist if the NNN market priced O’Reilly the same way the bond market does.
The spread exists because O’Reilly stores are small-format retail (typically 5,000 to 8,000 SF) on 0.5 to 1.0 acre lots in secondary commercial corridors. These are functional, purpose-built auto parts stores. They are not premium corner retail. The NNN market demands a cap rate premium for the smaller format, limited alternative use, and less prestigious locations. The bond market ignores all of this because the bond is backed by a $16 billion enterprise generating $3+ billion in annual EBITDA with one of the strongest balance sheets in specialty retail.
For investors who recognize that O’Reilly’s business is fundamentally internet-resistant (customers need parts immediately, require in-person expertise, and cannot wait for delivery when a vehicle is disabled), the NNN spread represents excess income on a credit that the bond market already validates as upper-medium investment grade.
O’Reilly vs. AutoZone: The Auto Parts Spread Comparison
O’Reilly and AutoZone are the two dominant rated auto parts NNN tenants. O’Reilly’s BBB+ / Baa1 rating is one notch above AutoZone’s BBB / Baa2, which translates to a slightly tighter bond yield (4.95% vs. 5.20%) and a slightly tighter NNN cap rate range (5.75% to 6.75% vs. 5.75% to 6.75%). The NNN cap rates overlap significantly because the market views the real estate formats as essentially identical. The spread is wider for AutoZone (55 to 155 bps) primarily because AutoZone’s bond yield starts higher due to the lower credit rating. Investors building an auto parts NNN portfolio can diversify across both tenants while capturing spreads in the 55 to 180 basis point range.
As of Q1 2026, the nominal spread is approximately 80 to 180 basis points. O’Reilly bonds yield roughly 4.95% while NNN properties trade at 5.75% to 6.75% cap rates. The after-tax spread is significantly wider due to depreciation sheltering NNN income from the ~45.8% combined tax rate that bond interest faces.
Auto parts demand is driven by immediate vehicle repair needs. When a car breaks down, the owner needs the part now, not in two days via shipping. O’Reilly’s network of 6,100+ stores provides same-day, in-person access to parts plus the technical expertise (loaner tools, diagnostic services, counterperson knowledge) that e-commerce cannot replicate. This demand pattern supports both the bond credit and the NNN lease durability.
O’Reilly NNN leases are typically 15-year absolute NNN with a corporate guarantee from O’Reilly Automotive, Inc. The tenant pays all property taxes, insurance, and maintenance. The bond is a senior unsecured obligation of the same corporate entity. Both instruments carry the same BBB+ / Baa1 credit backing. The NNN lease adds real estate collateral (you own the building) while the bond is an unsecured claim on corporate assets.
