08:56 AM EDT, 10/03/2025 (MT Newswires) -- Peabody Energy ( BTU ) said in a regulatory filing Friday that Anglo American has started arbitration proceedings over its decision to terminate purchase agreements related to Anglo's steelmaking coal assets.

"Peabody remains confident that a material adverse change occurred, entitling Peabody to terminate the purchase agreements," the company said in a filing with the US Securities and Exchange Commission.

Anglo has returned $29 million of the $75 million deposit due to Peabody, and Peabody has demanded the outstanding portion to be returned "without further delay," according to the filing.
