Peabody Energy Corp. is off to a bit of a rough start in trading on its first day back on the New York Stock Exchange following its bankruptcy reorganization.

The company's share price is down 12.1% to $27.25 per share at market close on April 4, following the company's April 3 announcement that it completed its bankruptcy reorganization. That share price put the "New BTU" at a market capitalization of about $493.3 million.

Several other coal companies fared better April 4. Arch Coal Inc. closed up 1.8%, Cloud Peak Energy Inc. was up 2.2% and Westmoreland Coal Co. rose about 2.0%.
