Cloud Peak Energy Inc. has amended its $500 million revolving credit facility to relax certain financial covenants, including the net secured debt leverage ratio and interest coverage ratio.

Michael Barrett, Executive Vice President and Chief Financial Officer, commented, “We are pleased to have relaxed our financial covenants under our $500 million credit facility. This amendment demonstrates our continued focus on actively managing our balance sheet and provides additional financial flexibility.”

On September 5, 2014, Cloud Peak Energy Resources LLC (the “Company”) entered into the First Amendment to Credit Agreement (the “Amendment”) which amends its Credit Agreement, dated as of February 21, 2014, among the Company, the guarantors party thereto, PNC Bank, National Association, as administrative agent, and a syndicate of lenders (the “Credit Agreement”). The Amendment relaxes the financial covenants under the Credit Agreement based on EBITDA (as defined in the Credit Agreement), which now require the Company to maintain (a) a ratio of EBITDA to consolidated net cash interest expense equal to or greater than 1.50 to 1 from September 30, 2014 to maturity (reducing this from the prior requirement under the Credit Agreement to maintain a ratio equal to or greater than 2.00 to 1), and (b) a ratio of senior secured funded debt less unrestricted cash and marketable securities (net secured debt) to EBITDA equal to or less than 4.00 to 1 from September 30, 2014 to maturity (increasing this from the prior requirement under the Credit Agreement to maintain a ratio equal to or less than (i) 3.00 to 1 through December 31, 2015, (ii) 2.75 to 1 from January 1, 2016 to December 31, 2016, and (iii) 2.50 to 1 from January 1, 2017 to maturity).
