O'Reilly Automotive Inc has placed a $10 billion bid to acquire Genuine Parts Company's aftermarket auto parts unit, which includes Napa Auto Parts, Motor1.com reported, citing a Bloomberg report based on people familiar with the matter. Genuine Parts has not said whether it will accept the bid, keep the unit, or sell it to another bidder, according to Motor1.com's July 7, 2026 report.
The bid follows a move Genuine Parts made months earlier. The company announced in February that it wanted to separate its auto parts unit and industrial operations into two publicly traded companies, Motor1.com reported. "Creating two focused, independent companies sharpens customer and market alignment, increases clarity and speed, simplifies operations and enables disciplined, business-specific investments to unlock long-term value," Will Stengel, Genuine Parts' chief executive, said at the time, according to the outlet.
The scale is not small. Genuine Parts' auto operations span more than 10,000 locations worldwide, including in Australia, with more than 6,000 Napa Auto Parts stores in the United States, Motor1.com reported. The auto unit brought in more than $15 billion in sales in 2025, its 100th year in business, according to the outlet.
It is unclear what O'Reilly Automotive plans to do with the acquisition, Motor1.com reported. Bloomberg's sources told the outlet an announcement could come as soon as this summer, with Genuine Parts expected to complete the split by early 2027.
The report moved both stocks the same day. Genuine Parts shares rose 13 percent. O'Reilly Automotive shares fell 2.6 percent, Motor1.com reported. Investors have leaned toward companies with simpler, single-focus portfolios amid volatility in the automotive industry, according to the outlet.
What it means at the parts counter
Nothing changes at a
Napa counter this week. A bid is not a signed deal, and Genuine Parts has not confirmed a timeline beyond the split it announced in February. A shop with an open account at a Napa store can confirm directly with that location whether ordering terms have shifted, rather than assume anything before a deal, if one happens, actually closes.
The bigger question for a reman shop is who ends up negotiating national account pricing once a deal like this settles. That doesn't touch interchange. A remanufactured engine or transmission fits the same years and models the day after ownership changes as it did the day before — wide interchange doesn't move with a change of parent company the way a narrow used-parts window can shrink as a donor vehicle ages out.
The number
$15 billion — what Genuine Parts' auto operations, including Napa Auto Parts, generated in sales in 2025, the unit's 100th year in business, Motor1.com reported, citing the Bloomberg account of the bid.
Terms
- **Interchange:** the list of years and models a given part fits. Remanufactured engines and transmissions carry wide interchange; used parts carry a narrow, two-to-three-year window.
- **Core charge:** a refundable deposit on the old unit the rebuilder needs back.
