Calgon Carbon Chairman Will Retire

Agrees to remain in position until replacement is found

Calgon Carbon Corp. announced that its chairman, president and CEO, John S. Stanik, has decided to retire to spend time with his family. Stanik has agreed to stay with the company in his current position until his replacement is put into place. Calgon Carbon’s board of directors will immediately begin a search to recruit Stanik’s replacement and expects to fill the position by the end of the third quarter of this year.

“This has been one of the most difficult decisions of my career,” Stanik said. “I remain very enthusiastic about Calgon Carbon Corp. and its future, but circumstances dictate that I attend to my family. Fortunately, Calgon Carbon has extremely talented senior leadership who I am very confident will continue to move the company forward.”

“Calgon Carbon Corp. has seen tremendous growth under John’s leadership and is poised for additional growth and profitability,” said lead director Seth Schofield. “We thank John for his 21 years of service to the company and appreciate his agreement to stay with us while we make an orderly management transition. We will miss his leadership.”
