# Paccar Moat

Status: published. Policy: company-analysis-1.

PACCAR has a narrow moat centered on its installed truck base and established aftermarket distribution and service system. Repeated parts price realization and continuing service-contract demand support a current advantage, although switching friction is inferred rather than measured. Truck pricing recovered in the first half of 2026 after competitive price declines in 2025, but falling market shares and parts volumes show erosion pressure. The passages do not establish a wide moat or structural cost leadership.

## switching_costs

The installed truck base creates recurring parts and service demand served through an established dealer and distribution system. This supports a modest aftermarket advantage through service continuity and convenience; proprietary lock-in, exclusive purchasing and quantified switching costs are not established.

Durability: Parts demand extends over vehicle lives, with sales generally concentrated in the first five years. Distribution infrastructure and growing maintenance-contract volume support persistence, but continued truck sales and competitive service remain necessary.

Risks: Parts volumes declined in 2025 and the first half of 2026 despite price realization. Lower truck market shares can weaken future installed-base replenishment. Alternative powertrains could change maintenance requirements; development spending is not evidence of a successful transition.

Invalidation: The thesis would be invalidated by sustained loss of aftermarket demand relative to the serviced installed base, inability to realize parts prices without persistent volume deterioration, or evidence that customers readily replace PACCAR service and parts with equivalent alternatives without meaningful inconvenience.

Competitors: Not established
