The securities litigation law firm of Brower Piven, A Professional Corporation, has commenced an investigation into possible breaches of fiduciary duty to current shareholders of OBA Financial Services, Inc. (“OBA” or the “Company”) (NasdaqCM: OBAF) and other violations of state law by the board of directors of OBA relating to the proposed buyout of the Company by F.N.B. Corporation (“FNB”). OBA is headquartered in Maryland. Brower Piven is the only firm headquartered in Maryland with a practice dedicated primarily to shareholder class action litigation. Under the terms of the transaction, OBA shareholders will receive 1.781 shares of F.N.B. Corporation stock for each share of OBA common stock they own. The firm’s investigation seeks to determine, among other things, whether the Company’s board of directors breached their fiduciary duties by failing to maximize shareholder value before agreeing to enter into this transaction, and whether F.N.B. is underpaying for OBA shares.
