It produces metallurgical coal used in steelmaking and thermal coal used for power generation and industrial purposes, with mining operations in West Virginia, Pennsylvania, the Powder River Basin, and Colorado, and sales to domestic and international markets.[1][2]

The company says its purpose is “discovering, producing, and providing precious natural resources in the service of human progress.” [3] Core was formed on January 14, 2025, when CONSOL Energy completed an all-stock merger with Arch Resources and adopted the Core Natural Resources name.[4] It reported $4.165 billion in revenue for 2025 and $2.225 billion for the six months ended June 30, 2026.[5][6] The company reports approximately 5,000 or more employees.[7] [1]+8

Company history

Core Natural Resources traces part of its coal-mining heritage to 1864. One of its predecessors, Arch Mineral Corporation, was organized in 1969 and merged with Ashland Coal in 1997; Arch later became Arch Coal and adopted the name Arch Resources in 2020.[3]+2

A separate predecessor, CONSOL Energy, became an independent public company in 2017 when CNX spun off its coal business. In August 2024, CONSOL and Arch announced an all-stock merger of equals. The merger closed on January 14, 2025: CONSOL was renamed Core Natural Resources, Inc., while Arch became its wholly owned subsidiary, and the company began trading as CNR the following day. At formation, Jimmy Brock became executive chair and Paul A. Lang CEO; Brock succeeded Lang as CEO in October 2025.[26]+4 [4]+7
