The securities litigation law firm of Brower Piven, A Professional Corporation, has commenced an investigation into possible breaches of fiduciary duty and other violations of state law by the Board of Directors of Tobira Pharmaceuticals, Inc. (Nasdaq: TBRA) ("Tobira Pharmaceuticals" or the "Company") relating to the proposed buyout of Tobira Pharmaceuticals by Allergan plc. Under the terms of the agreement, Tobira Pharmaceuticals shareholders are anticipated to receive an upfront payment of $28.35 per share, in cash, and up to $49.84 per share in Contingent Value Rights (CVRs) that may be payable based on the successful completion of certain development, regulatory and commercial milestones, for each share of Tobira Pharmaceuticals common stock. The firm's investigation seeks to determine, among other things, whether the Company's Board of Directors failed to satisfy their duties to shareholders, including whether the Board adequately pursued alternatives to the acquisition and whether the Board obtained the best price possible for the Company's shares of common stock.
