Marketplace Partner Threatens Termination
In October 2026 a large third-party marketplace partner sent a letter saying the planned CarParts Connect launch creates a conflict of interest and that it intends to terminate the seller relationship when that launch occurs; management expects weeks-to-months of discussions with no assurance of a resolution.

Marketplace Channel Is 30.3% of Sales
Sales on third-party marketplaces including eBay and Amazon were a combined 30.3% of total sales in the thirty-nine weeks ended October 3, 2026, so a termination would put a large slice of revenue at risk.

Analysis · PRTS · Trade & Services
The quarter itself was already public: net sales of $129.3 million, up 1.2%, and Adjusted EBITDA of $1.0 million versus $(2.5) million a year ago. What is new in the 10-Q is the risk disclosure that in October 2026 a large third-party marketplace partner wrote that the planned CarParts Connect launch creates a conflict of interest and that it intends to terminate the seller relationship when that launch occurs. Marketplace sales were 30.3% of total sales in the first nine months of 2026, so losing one large channel would hit roughly a third of revenue — that is the fact that changes the thesis, not the earnings print. Cash of $33.8 million and positive operating cash flow of $10.0 million give the company room to negotiate, but management explicitly says there is no assurance of a resolution.
