Walter Energy Announces Voluntary Delisting From Toronto Stock Exchange

BIRMINGHAM, AL — Apr. 28, 2014 — Walter Energy, Inc. (NYSE: WLT) (TSX: WLT) today announced that shares of its common stock will be voluntarily delisted from the Toronto Stock Exchange (“TSX”) at the close of markets on May 7, 2014 pursuant to the Company’s application for voluntary delisting which has received approval from the TSX.

Walter Energy’s decision to delist was primarily based on the low trading volume of its shares on the TSX over a sustained period, no longer justifying the financial and administrative costs associated with maintaining a dual listing. Following its delisting from the TSX, Walter Energy’s shares will continue to trade on the New York Stock Exchange (“NYSE”) under the symbol “WLT”. Canadian shareholders will be able to continue to trade their shares of Walter Energy on the NYSE.
