Peabody Energy signed a definitive agreement to buy the Shoal Creek metallurgical coal mine from private coal producer Drummond Co. for US$400 million. The mine is located in central Alabama and serves Asian and European steel mills with high-vol A coking coal. The transaction, which could close before year-end, involves the purchase of the mine, preparation plant and supporting assets, but excludes legacy liabilities other than reclamation. Glenn Kellow, the company's president and CEO, said in a press release that buying "the well-capitalized and high-quality" Shoal Creek mine meets the company's goal of upgrading its metallurgical coal platform through strategic investments, and "offers major logistical advantages and represents an opportunity to create significant value." Benjamin Nelson, vice-president and senior credit officer at Moody's Investors Service, said in a note that the acquisition is "credit positive, based on expectations for the company to fund the transaction out of cash without diminishing liquidity." At the end of June, Peabody reported a cash balance of nearly US$1.5 billion. Peabody's shares ended at US$42.01 apiece, down US$1.75.
