Minerals Technologies to Acquire AMCOL International

MTI and AMCOL Enter into Definitive Merger Agreement   

NEW YORK, NY and HOFFMAN ESTATES, IL-March 10, 2014-Minerals Technologies Inc. MTX and AMCOL International Corporation ACO announced today that they have signed a definitive merger agreement under which MTI will acquire AMCOL for $45.75 per share in cash, or a total value of approximately $1.7 billion.

Muscari, chairman and chief executive officer of Minerals Technologies. "We will be a leading industrial minerals company with more than $2 billion in sales, strong market positions, and a dedicated team focused on customer needs. We look forward to welcoming AMCOL employees to MTI. Together, we will be better positioned to take advantage of even more opportunities for innovation and growth in the global minerals industry."

Ryan McKendrick, chief executive officer of AMCOL, said: "This transaction demonstrates the AMCOL Board's commitment to maximizing value for our shareholders. We look forward to working with Minerals Technologies to ensure a smooth transition and complete the transaction as expeditiously as possible."
