Lear is a Tier-1 automotive supplier — it doesn't build cars, it builds the two systems inside almost every car: the seats you sit in (73.9% of sales) and the electrical 'nervous system' of wiring, connectors and power electronics that routes signals and current through the vehicle (26.1%). It sold $23.3B of both to the world's automakers in 2024, with General Motors alone accounting for 22% of revenue.
Where Lear sits in the car
Lear is a Tier-1 supplier — the layer between raw materials and the automaker. Steel, copper, foam and chips flow in; complete seat systems and finished wire harnesses flow out, delivered just-in-time straight to GM, Ford, VW and BMW assembly lines. Lear never builds a whole car; it owns two systems inside almost every car.
