Cummins Inc. — AI supply-chain exposure

Cummins is an engine and power-systems specialist whose power-generation business supplies the high-horsepower generator sets widely specified for data center standby power. Where Caterpillar reaches this market through a broader machinery portfolio, Cummins sits closer to a pure engine-and-genset supplier — from the diesel block itself to the switchgear and controls wrapped around it.

Standby power is a design requirement, not an option, so genset demand scales with the square footage of data center that gets built. Cummins compounds that with durable aftermarket revenue, servicing a fleet that runs for decades once installed. The model places it in the backup-generation layer: a component supplier one step from the grid, whose exposure is to the pace of construction and to power scarcity that pushes operators toward generating their own.
