CLOUD PEAK ENERGY INC. ANNOUNCES RESULTS

FOR THIRD QUARTER AND FIRST NINE MONTHS OF 2018

Gillette, Wyo. (BUSINESSWIRE) — 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, today announced results for the third quarter and first nine months of 2018.

Colin Marshall, President and Chief Executive Officer, commented, “Third quarter shipments from our Antelope Mine were reduced due to significant ongoing spoil failures that started in mid-August related to the rain in the second quarter.  The spoil failures will reduce fourth quarter shipments as pre-stripping was delayed when equipment was diverted to deal with them.  We are working with our customers to move Antelope tons to our other mines or into 2019 where possible.  Exports went very well during the quarter, though the recent drop in the Kalimantan price index will reduce fourth quarter logistics earnings.  Our third quarter results included a one-time, non-cash gain of $19.5 million relating to the winding up of our postretirement medical plan that should be considered when assessing our financial performance.”

Third Quarter Highlights

·                  Shipments were 13.1 million tons during the third quarter of 2018 compared to 15.5 million tons for the third quarter of 2017.  Lower shipments resulted primarily from our Antelope Mine as work continued to mitigate significant mid-August spoil failures resulting from heavy rains in the second quarter.

·                  Exported 1.5 million tons during the third quarter of 2018 at prices higher than those realized in 2017 and have contracted 4.9 million tons for 2018 delivery.  As previously announced, we have amended and extended the existing Westshore throughput agreement to increase annual capacity from 5.5 million tons to 10.5 million tons in 2021 and 2022.

·                  Announced the termination of our postretirement medical plan, which reduced our liability by approximately $25 million.  A non-cash gain of $19.5 million is reflected in net income and Adjusted EBITDA for the third quarter of 2018.  An additional non-cash gain of $8.2 million will be released ratably through the plan termination date of December 31, 2019.

·                  Net income was $12.7 million for the third quarter of 2018 compared with net income of $2.6 million during the third quarter of 2017.  Adjusted EBITDA was $40.7 million during the third quarter of 2018 compared to $36.0 million for the third quarter of 2017.  Both net income (loss) and Adjusted EBITDA for 2018 include the $19.5 million non-cash gain noted above.  In addition, the third quarter results include our quarterly mark-to-market adjustments for certain performance share units, which resulted in a $5.3 million non-cash gain during the quarter.

·                  The lower operational results in the third quarter of 2018 further compressed our availability under our Credit Agreement, and we ended the quarter with liquidity of $131.6 million, of which $109.5 million was cash and cash equivalents.

·                  Cost reduction efforts continued with the announced move of our corporate headquarters to an existing structure at our Cordero Rojo Mine scheduled to be completed by year end.
