Canonical: https://valuechain.wiki/komatsu · Facet: ripple · Updated: 2026-09-23T09:58:34.926218+00:00 · Source: ValueChain.wiki (cited money-flow graph)

**Citable summary**: Per the valuechain.wiki graph, Komatsu is directly linked to 4 companies (2 supply, 2 revenue relationships) and reaches 7 companies within two hops; the links are backed by 11 dated sources, 1 of them primary filings (as of 2026-09-23).

Komatsu operates across Nikkei 225, Mining & construction equipment, No.1 in autonomous trucks. It stayed steadily positive in recent years and is +28.3% in 2026. The stock (+28.3%) and its supply side (avg +39.7%) are moving in step. Among connected nodes the furthest ahead is Ouster (+68.3%) and the furthest behind is Cummins (+11%). If chain logic explains the gap, the laggard is the next propagation candidate; if not, the link itself deserves a second look. tariffs (guidance: OP -10.5%) erode that pricing power, and how much the mining-automation and aftermarket moat cushions the downside.
