The securities litigation law firm of Brower Piven, A Professional Corporation, announces that a class action lawsuit has been commenced in the Missouri Circuit Court, St. Louis County, on behalf of all common stockholders of Sigma-Aldrich Corporation (“Sigma-Aldrich” or the “Company”) (NASDAQ: SIAL) relating to the proposed buyout of the Company by Merck KGaA (“Merck”).

The complaint arises out of the September 22, 2014 announcement that Sigma-Aldrich had entered into a definitive merger agreement with Merck, pursuant to which Sigma-Aldrich shareholders will receive $140.00 in cash for each share of Sigma-Aldrich common stock they own.

The complaint seeks relief on behalf of the named plaintiff and all other similarly situated shareholders of Sigma-Aldrich and asserts whether the Company’s Board of Directors breached their fiduciary duties by failing to maximize shareholder value and/or protect the interests of Sigma-Aldrich shareholders.
