Levi & Korsinsky is investigating the Board of Directors of Firstbank Corporation (NasdaqGS: FBMI) (“Firstbank” or “the Company”) for possible breaches of fiduciary duty and other violations of state law in connection with the sale of the Company to Mercantile Bank Corp. (NasdaqGS: MBWM). Click here to learn more about the investigation http://zlk.9nl.com/firstbank-fbmi/, or call: 877-363-5972. There is no cost or obligation to you. Under the terms of the transaction, Firstbank shareholders will receive one share of Mercantile common stock for each share of Firstbank common stock they own. This represents a value of approximately $18.77 per share. Upon completion of the merger, Firstbank shareholders will own 48% of the post-merger company. The investigation concerns whether the Firstbank Board of Directors breached their fiduciary duties to stockholders by failing to adequately shop the Company before agreeing to enter into the transaction, and whether Mercantile Bank Corporation is underpaying for Firstbank, thus unlawfully harming Firstbank shareholders.
