Equipment sales are cyclical. Services revenue is not. Caterpillar's aftermarket parts, maintenance agreements, and digital fleet management solutions now generate roughly $16-17 billion annually — up from $11 billion five years ago. This revenue carries operating margins above 25%, compared to 12-14% for new equipment sales.
The installed base of Caterpillar equipment exceeds 3.5 million machines globally. Each machine requires parts, service, and increasingly, digital connectivity for predictive maintenance and fleet optimisation. Cat's dealer network — 156 independent dealers with 2,700 branch locations — creates a physical moat that no competitor can replicate. Komatsu and Volvo CE compete on equipment. Nobody competes on aftermarket.
We tracked this same dynamic in the aviation aftermarket fifteen years ago. When Honeywell and GE Aviation shifted their investor narratives from equipment cycles to installed-base servicing, the multiples re-rated by 40-60% over three years. Caterpillar is earlier in that same arc.
The mining capex supercycle adds another dimension. Copper, lithium, and rare earth mining projects are in the early stages of a multi-decade buildout driven by electrification. Caterpillar's autonomous mining trucks — already operating at 35+ sites globally — position it as the default supplier. Look, nobody buys mining stocks for the equipment vendor. But at $10 billion in annual FCF, the equipment vendor is looking increasingly attractive.
