O REILLY AUTOMOTIVE INC · 2026-11-06 · Importance 18 · Surprise 14

O’Reilly identifies miles driven, the number of registered vehicles, light-vehicle sales, and average vehicle age as long-term drivers of aftermarket demand. U.S. miles driven increased 0.5% year to date through August 2026, while the U.S. vehicle fleet reached 289 million light vehicles at year-end 2025 and average vehicle age rose to 12.8 years. The company expects the growing fleet and older, increasingly out-of-warranty vehicles to support demand for repair and maintenance products. Older vehicles generally require more frequent maintenance and mechanical repairs, supporting aftermarket demand.
