The Federal Trade Commission has filed an administrative complaint challenging a proposed joint venture between Peabody Energy Corporation and Arch Coal. The transaction would combine their coal mining operations in the Southern Powder River Basin, located in northeastern Wyoming. The admininstrative complaint alleges that the transaction will eliminate competition between Peabody and Arch Coal, which are the two major competitors in the market for thermal coal in the Southern Powder River Basin, and the two largest coal-mining companies in the United States. This civil case seeks a temporary restraining order and preliminary injunction enjoining the defendants from consummating their joint venture. The Commission votes to issue the administrative complaint and to authorize staff to seek a temporary restraining order and preliminary injunction were both 4-1. The administrative trial is scheduled to begin on Aug. 11, 2020.
