NACCO Industries operates three primary segments: surface coal mining for power generation under the North American Coal brand, contract mining services at limestone quarries and sand/gravel mines through North American Mining, and oil and gas royalty interests through Catapult Mineral Partners. The company supplies coal exclusively to utility customers under long-term contracts with monthly price adjustments, provides specialized mining services at customer-owned sites (with over 80% of quarries in Florida), and collects royalties from third-party operators on its oil and gas acreage across multiple U.S. basins with no exploration costs borne by NACCO. The company also pursues complementary growth through environmental mitigation services and renewable energy development on reclaimed mine properties, generating revenue from long-term coal contracts and management fees, customer-reimbursed mining costs, and commodity-based royalties.
