Fraser is an experienced executive in the chemicals industry, and has been CEO of two chemical companies. He has served on KMG’s board since 2008 and as chairman of the board since December 2012. In his role as interim CEO, Fraser will lead the business, in conjunction with KMG’s existing management team.“Our recently completed acquisition of the Ultra Pure Chemicals business from OM Group results in a company one-third larger in terms of revenue and with expanded global breadth,” Fraser said. “As the company pursues its growth strategy in selected specialty chemicals markets, our challenges and opportunities will necessarily increase given KMG’s expanded operations in Europe and first physical presence in Asia. The selection criteria for the next CEO reflect this new stage in the company’s growth and the skills and experience that the future will require,” he said. J. Neal Butler biographical information J.
