Mining Equipment OEMs: Competitive Position, Fleet Electrification, and Aftermarket Economics

The global mining-equipment market was worth roughly $62 billion in 2024, dominated by Caterpillar, Komatsu, Epiroc, Sandvik, Liebherr, and Weir, with the top five holding around 54% of revenue and three suppliers controlling most underground loading and haulage. Caterpillar's Resource Industries backlog rose to about $51 billion at the end of 2025 from $30 billion a year earlier, reflecting an aging installed base and high utilization. Aftermarket parts and service, more than half of divisional revenue at Epiroc and Sandvik, provides a higher-margin and less cyclical earnings base than new-equipment sales. Fleet electrification is the central capital decision, requiring development spend well ahead of customer replacement cycles, while Chinese challengers are compressing surface-equipment pricing in emerging markets.
