### Barrick (네바다 골드마인스) (high)
- note: AHS customer where Komatsu's 1,000th ultra-class autonomous truck (930E-5AT, 290t) was commissioned (Apr 2026).
- [confirms] Komatsu (EN, filing, published 2026-04-28) https://www.komatsu.jp/en/-/media/home/ir/library/financial/en/2603q4_e.pdf: "Cumulative AHS mining trucks reached 1,016 units as of end-March 2026."

### Rio Tinto (high)
- note: FrontRunner AHS and 830E/930E truck customer at Pilbara iron mines (Brockman 4, West Angelas).
- [confirms] Mining Technology (EN, news, published 2023-01-01) https://www.mining-technology.com/features/autonomous-haulage-systems/: "Rio Tinto ordered 29 AHS retrofit kits for 830E trucks at Brockman 4."

### Vale (high)
- note: 830E/930E truck customer at Carajas; 2024 Dual Fuel (up to 70% ethanol) retrofit program with Cummins.
- [confirms] Komatsu (EN, ir, published 2024-08-27) https://www.komatsu.jp/en/newsroom/2024/20240827: "Retrofitted trucks run up to 70% ethanol, cutting direct CO2 up to 70%."

### 북미·중남미·오세아니아 자원국 (건설·광산기계) (high)
- note: In construction & mining — 92% of sales — the resource cycle is what is holding the company up: copper, iron-ore and gold prices lifted Latin American (+13.7%) and Oceania mining demand, offsetting the collapse in Asian (-33%) and Japanese (-4.6%) general construction as infrastructure softened. The segment's +0.2% came from price increases, not volume, so segment profit still fell 18% on cost and volume — a classic late-cycle signature. What threatens that pricing power is the FY2027 U.S. tariff hit (guidance: operating profit -10.5%).
