Core Natural Resources appoints Jimmy Brock as CEO

Core Natural Resources (CNR) announced that its board of directors has appointed Core’s board chair, Jimmy Brock, to the additional role of CEO, effective immediately. He succeeds Paul A. Lang, who is departing as CEO and board member. Brock will work closely with Lang, who has agreed to provide transition consulting services through the end of the year, as well as with the board and the management team, to ensure a seamless transition. Brock has served as executive chair of the Core Natural Resources board since January 14 when Core was formed via a merger between Arch Resources and CONSOL Energy. Prior to that time, Brock served as chairman and CEO of CONSOL Energy.
