OEM single-sourcing
What it is
A vehicle or equipment manufacturer awarding a part to one supplier for the life of a platform, rather than splitting volume across several. The supplier co-develops the component, tools for it and is validated into the assembly
It is the standard model in auto components, where switching mid-platform means requalification, retooling and warranty risk the OEM would rather avoid
Impact on industries
- Delivers multi-year revenue visibility tied to a platform's life, which supports capex planning in a way spot supply never could
- Switching costs are the moat - requalification and retooling are expensive enough that incumbency usually survives ordinary price pressure
- Concentration risk is the price: losing one platform removes a large revenue block at once, and the customer knows it during annual price negotiations
- OEMs extract contracted annual price reductions, so a supplier must take cost out yearly just to hold margin - and shortening platform life compresses tooling payback
