OEM portfolio divestiture is now a direct threat to supplier order books. When a customer sells a product category rather than simply winding it down, the supply chain around it does not end. It becomes a low-priority asset inside a private equity structure, and programme renewals stall quietly before they are ever cancelled formally.
For Tier 1 and Tier 2 suppliers, this is a sourcing and call-off risk, not an abstract strategy question. The platform you supply today may be owned by a different entity before your next RFQ lands.
Volkswagen Group has agreed to sell its heavy-duty diesel engine unit Everllence to Bain Capital in a deal generating approximately €7.4 billion. VW describes this sale as the beginning of a radical cost restructuring intended to free capital for electrification. At the same time, Schaeffler has set a target of ten percent of revenue from robotics, aerospace and defence by 2035, signalling its own exit from dependence on the classical automotive business. Both moves follow the same logic: exit ICE-adjacent assets and redeploy capital elsewhere.
The assets being sold today are the programmes being wound down tomorrow.
For a supplier staying on the next platform, three things matter now:
Which parts sit inside a product category your customer is actively trying to exit? A divestiture to private equity changes who controls platform renewal decisions and capital allocation. Budgets shrink before the programme formally ends.
Who owns your programmes after the sale closes? A new private equity owner has different margin targets and a different timeline than the OEM that originally sourced you. Contract continuity and call-off reliability are not guaranteed by the original sourcing agreement.
Does your order book beyond 2028 depend on ICE platform continuity? If the answer is yes and your customer has publicly flagged that unit for review, the risk is already priced in on their side, even if it has not reached your planning cycle yet.
Are any of your key programmes currently tied to a platform or unit your customer has publicly flagged for review?
If that question is worth a few minutes of honest thought, the DreCo diversification brief is a short read that maps exactly this kind of exposure. It covers the position work we do with Tier 1 and Tier 2 suppliers facing customer concentration and platform risk.
