What these concentrations mean together
updated 2026-06-24The company's concentration profile is defined almost entirely by supplier dependencies on two OEM relationships, one high-share and one medium-share, that together account for the substantial majority of the company's revenue-generating inventory. The dominant exposure is to PACCAR and its Peterbilt brand: the majority of revenues resulted from sales of trucks purchased from Peterbilt and parts purchased from PACCAR Parts. This is a high-share, dependency-type exposure by character — the dealership network is structured around a primary OEM relationship that determines the product lines, dealer agreements, parts pricing, and competitive positioning available to the company. A deterioration in the terms of that relationship, a change in PACCAR's dealer network strategy, or a sustained disruption to PACCAR production would directly affect the company's ability to generate revenue. The second, medium-share exposure is to International Motors, whose trucks (branded as International) and buses (IC Bus) together represent a significant portion of revenues. This is also a dependency in character: a franchise dealer relationship with an OEM is governed by contractual arrangements whose terms can be altered, and the company is subject to the commercial and financial health of this manufacturer. Together, the two supplier/OEM exposures constitute the primary concentration risk in the profile. The business is largely a function of the strength, terms, and product appeal of these OEM relationships rather than of independent customer diversification. There are no disclosed geographic or customer concentrations that would modify this picture, making OEM relationship quality the central monitoring variable. RUSHB shares the same fundamental concentration structure as the Class A shares, reflecting common underlying operations.
