On June 12, 2014, Cliffs Natural Resources issued the following statement in response to the filing of a definitive proxy statement by Casablanca Capital LP:

“The Company’s Board and new management team led by Gary Halverson have taken - and will continue to take - decisive steps to reduce costs and prudently allocate capital while steadily improving Cliffs’ financial and operating performance, including through the ongoing, comprehensive review of our portfolio of assets and strategic options. This Board and management team is best positioned to deal with the difficult price environment Cliffs is dealing with today. Change is already underway at Cliffs and we remain committed to enhancing value for all of our shareholders. Based on discussions with various shareholders, the Board of Directors is nominating a slate of nine directors for its eleven-person Board. As a result, we believe that at least two of Casablanca’s proposed nominees will be elected to the Cliffs Board, so shareholders should vote using the Company’s WHITE proxy card.”
