Komatsu: The Rival in Every ArenaNarrow moat

Caterpillar (CAT) — moat facet

Komatsu is the one rival Caterpillar names in construction, surface mining and underground mining alike.

Of all the companies Caterpillar lists, one appears in every machine arena. Komatsu is named among the global construction competitors, among the surface mining competitors and among the three underground mining competitors, alongside Epiroc and Sandvik1. Deere, Hitachi and Volvo appear in construction and surface mining; Komatsu alone appears in all three lists2.

One rival everywhere.

That makes Komatsu the rival Caterpillar's customers can most easily compare it with, machine for machine and mine for mine. A mining company that runs Caterpillar trucks can run Komatsu trucks; a contractor with Caterpillar excavators can buy Komatsu's.

The contest is decided less by the machine than by what surrounds it. Caterpillar's advantage is its dealers, who in most cases make Caterpillar their principal business3, and its autonomy: the company ended 2025 with 827 autonomous haul trucks in operation, up from 690 at the end of 20244.

Caterpillar does not disclose market shares, so the contest can only be read through its own figures. In mining, Resource Industries' sales of $3,685 million to mining, heavy construction and quarry customers rose 22% in the second quarter of 20265, driven by demand for copper and gold6.

The autonomy race is where the contest is most visible. Caterpillar's autonomous haul truck fleet grew from 690 to 827 in 20257, and its agreement with Vale for a mixed fleet of more than 90 trucks8 shows it will run its autonomy on other makers' machines. That is a direct move against rivals whose trucks share the same mines.

This is a rivalry between equals in engineering and unequals in distribution. Resource Industries' margin is the gauge: 15.9% in 2025 on the annual report's basis910; if it falls further while mining demand is strong, Komatsu and the others are winning on price.

Moat trajectory: Holding steady

Mining sales +22% in Q2 2026; autonomous fleet growing.

Caterpillar's side of the Komatsu contest; a falling margin while mining demand is strong would mean rivals are winning on price.
