Former Attorney General of Louisiana Charles C. Foti, Jr., Esq. and the law firm of Kahn Swick & Foti, LLC (“KSF”) are investigating the proposed sale of Summit Materials, Inc. (“the Company”) (NYSE: SUM) to Cementos Argos S.A. (OTC: CMTOY). Under the terms of the proposed transaction, Cementos will receive approximately 54.7 million shares of Summit stock and approximately $1.2 billion in cash, subject to closing adjustments. Upon closing of the proposed transaction, Cementos will own approximately 31% of the combined company on a fully diluted basis. KSF is seeking to determine whether this consideration and the process that led to it are adequate, or whether the consideration undervalues the Company.

If you believe that this transaction undervalues the Company and/or if you would like to discuss your legal rights regarding the proposed sale, you may, without obligation or cost to you, e-mail or call KSF Managing Partner Lewis S. Kahn (lewis.kahn@ksfcounsel.com) toll free at any time at 855-768-1857, or visit https://www.ksfcounsel.com/cases/nyse-sum/ to learn more.
