Press Releases

Peabody Energy has submitted a definitive proposal to acquire a controlling interest in Macarthur Coal Limited . Under Peabody's revised proposal, Macarthur shareholders would receive a cash price of A$15.00 per share, valuing Macarthur at A$3.8 billion (US$3.4 billion) under a scheme of arrangement.

The definitive proposal delivers a clear, compelling and significant premium for Macarthur shareholders, and follows Peabody's due diligence as well as the introduction of the Australian resources profit tax proposal.

  Peabody's A$15.00 per share proposal represents:
  --  A 31 percent premium to A$11.48 per share, which was the 30-day
      volume-weighted average share price up to March 30, 2010, the day
      before Macarthur announced Peabody's initial proposal; and
  --  A 42 percent premium to A$10.57 per share, the 90-day volume-weighted
      average share price up to March 30, 2010.

With this definitive proposal now in place, Peabody encourages the Macarthur Board to move to a quick resolution to resolve the uncertainty for Macarthur shareholders.

Under the proposal, Peabody is prepared to offer cash to all Macarthur shareholders and continues to be willing to provide any, or all, of Macarthur's three major shareholders with the opportunity to retain their economic interest in Macarthur should they so desire.

Peabody Energy is the world's largest private-sector coal company, with 2009 sales of 244 million tons and $6 billion in revenues. Its coal products fuel 10 percent of all U.S. electricity generation and 2 percent of worldwide electricity.
