AI brief of an SEC Form 8-K · Core Natural Resources (CNR)

Core Natural Resources names board chair Jimmy Brock CEO as Paul Lang departs

Neutral Impact 4 of 5 leadership Written later

Core Natural Resources' board appointed James A. Brock, who is also board chair, as chief executive officer effective October 6, 2025, succeeding Paul A. Lang, who resigned as CEO and as a board member. Lang will provide transition consulting through December 31, 2025, and the company expects to pay him a lump sum and settle his equity awards under a separation agreement that is still being finalized, which matters to shareholders because it changes the company's top executive role and adds to its severance costs.

Key points

  • James A. Brock was appointed CEO effective immediately on October 6, 2025, and will continue as Chair of the Board.
  • Paul A. Lang separated from service and resigned from the board; he will consult through December 31, 2025.
  • Expected lump sum cash payment of $7,950,553 to Lang, subject to a release, plus performance-based RSUs settled in cash at $88.45 per share, the October 6, 2025 closing price.
