CNR

Core Natural Resources, Inc.

A major North American coal producer, formed in January 2025 through a "merger of equals" between two long-time rivals, CONSOL Energy and Arch Resources. It mines both metallurgical coal for steelmaking and thermal coal for power generation, running longwall mines in Pennsylvania and operations in Appalachia. Its roots run deep: CONSOL traces back to the Consolidation Coal Company, founded in 1860 when western Maryland operators joined together to "consolidate" their holdings.
