AMCOL International Corporation Confirms Receipt of Revised, Unsolicited Proposal from Minerals Technologies

The AMCOL Board of Directors, in consultation with its financial and legal advisors, will carefully review and consider the Revised MTI Proposal and pursue the course of action that it believes is in the best interests of the Company's stockholders. 

As previously announced, on February 11, 2014, AMCOL entered into a definitive merger agreement with Imerys S.A. (the "Imerys Agreement") pursuant to which AMCOL shareholders would receive $41.00 per share in cash for each share of AMCOL common stock that they own.  There can be no assurance that AMCOL's Board of Directors will determine the Revised MTI Proposal to be superior to the Imerys Agreement. Furthermore, the AMCOL Board of Directors continues to recommend the transaction with Imerys to its stockholders and is not withdrawing its recommendation, or proposing to do so, at this time.   

Goldman, Sachs & Co. is serving as exclusive financial advisor to the Company and Kirkland & Ellis LLP is serving as counsel to the Company.
