2011 Third Quarter and Nine Months Highlights

• Adjusted EBITDA¹ of $87.9 million in the third quarter of 2011 compared with $94.5 million in the third quarter of 2010; Adjusted EBITDA of $258.8 million compared with $253.1 million for the first nine months of 2010.
• Net income of $24.6 million resulting in Adjusted EPS¹ of $0.61 compared to $0.60 in the third quarter of 2010; for the nine months 2011, net income of $146.0 million resulting in Adjusted EPS of $1.78 compared to $1.39 in the first nine months of 2010.
• Diluted EPS of $0.41 compared to a loss of $0.22 in the third quarter of 2010; diluted EPS of $2.41 compared to $0.68 in the first nine months of 2010.
• Asian exports were up approximately 48 percent to 1.4 million tons from 0.9 million tons in the third quarter of 2010.  For the first nine months, Asian exports were 3.7 million tons up 47 percent from 2.5 million tons exported in the first nine months of 2010.
• Cash and cash equivalents increased to $437.6 million during the third quarter of 2011 following the release of $86.6 million from previously restricted cash, and cash flow from operations of $93.7 million in the third quarter.

“Our third quarter was highlighted by our mines’ continued strong operating performance and the continued expansion of our Asian exports by 48 percent over the third quarter of last year,” said Colin Marshall, President and Chief Executive Officer.  “Flooding in the Midwest affected railroad performance from May to September; however, by late September the railroads' performance had returned to normal, which has allowed us to improve our full-year guidance.  Costs are under control and our exports are expected to be above 4.5 million tons for the full year.”

For the third quarter, sales from our three company-operated mines were 24.4 million tons, down from 25.1 million tons in the third quarter of 2010 due to flood related interruptions to rail services which reduced shipments from May to mid-September.  Adjusted EBITDA declined slightly to $87.9 million, driven by lower volumes.  Realized price per ton increased to $12.91.  Average cost of product sold per ton was $9.17, up from last year due to the lower volumes mined, higher diesel prices, increased repairs and maintenance, and higher strip ratios.  For the first nine months, we generated Adjusted EBITDA of $258.8 million up from $253.1 million for the same period in 2010 driven by strong export sales and higher realized prices.

Gillette, WY, October 21, 2011 – Cloud Peak Energy Inc. (NYSE:CLD), one of the largest U.S. coal producers and the only pure-play Powder River Basin (PRB) coal company, is providing third quarter 2011 production data for its Cordero Rojo mine.  It has come to the company’s attention today that due to an administrative error the production data presented on the Mine Safety and Health Administration (MSHA) website was inaccurate.  For the third quarter of 2011, Cordero Rojo produced approximately 9.9 million short tons.   

Cloud Peak Energy will announce its third quarter 2011 results on October 27, 2011, after the markets close.  Refer to the company’s October 17, 2011 press release for access information regarding the company’s upcoming quarterly earnings announcement.
