The law firm of Finkelstein Thompson LLP is investigating potential claims on behalf of shareholders of Firstbank Corporation (NASDAQ: FBMI) (“Firstbank” or “the Company”), concerning the Company’s proposed acquisition by Mercantile Bank Corp. (NASDAQ: MBWM) (“Mercantile”). Under the terms of the merger agreement, Firstbank shareholders will receive a fixed ratio of one share of Mercantile common stock for each share of Firstbank common stock they own. This implies a transaction value of $18.77 per share based on the closing price of Mercantile on Wednesday, August 14, 2013. The total deal is valued at approximately $151.5 million. The investigation is focused on the potential unfairness of the consideration to shareholders, the process by which Firstbank’s Board of Directors considered the transaction, and potential conflicts of interest among the Company’s Board members.
