PITTSBURGH, PA--(Marketwired - January 13, 2016) - Koppers Inc., a wholly-owned subsidiary of Koppers Holdings Inc. (NYSE: KOP), today announced that it plans to substantially discontinue activities at its tar plant located in Clairton, Pennsylvania. The decision, which will affect 52 employees, was driven by the continued secular shift of primary aluminum production to lower-cost energy regions of the world, which has contributed to the overcapacity in the tar distillation industry. Recently announced closures and curtailments of significant capacity in the U.S. aluminum market have only exacerbated the situation.

The company plans to ramp down production at the Clairton facility over the next six months as it transitions production to other Koppers-owned facilities in both the U.S. and Europe, and has targeted a date of mid-2016 for discontinuing activities at the Clairton plant.

The company expects this action to result in pre-tax charges to earnings of $17 to $23 million through the end of 2019, which includes $7 to $10 million of non-cash impairment charges that are expected to be recorded in the fourth quarter of 2015.

The pre-tax cost savings related to discontinuing activities are estimated to be approximately $4 million for the year ended December 31, 2016 before reaching an annual run rate of approximately $14 million in 2017 and beyond.

Commenting on the decision, Koppers President and CEO Leroy Ball said, "In addition to the $14 million of expected annualized fixed cost avoidance benefits from closing Clairton, we also expect to realize increased profits on certain European products that can be diverted into the U.S. market at a higher value. Those benefits, in combination with lower raw material costs, are expected to more than offset the profitability that will be lost due to the reduction in demand of carbon pitch from the U.S. aluminum industry, which is expected to result in an approximate negative $40 million top-line impact on our CMC segment in 2016."

Mr. Ball continued, "Making a decision to cease operations at any of our plants is never an easy decision. The impact it has on our employees that have dedicated their careers to strengthening Koppers reputation in the industries that we serve is extremely unfortunate. Not only do I want to thank them for their service, but also pledge to have our company help them transition to other careers either within or outside of Koppers."
