The law firm of Brower Piven, A Professional Corporation, has commenced an investigation into possible breaches of fiduciary duty to current shareholders of Catalyst Health Solutions, Inc. (NASDAQ: CHSI) (“Catalyst”) and other violations of state law by the board of directors of Catalyst relating to the proposed acquisition of the company by SXC Health Solutions Corp. (“SXC”). The firm’s investigation seeks to determine, among other things, whether the board breached its fiduciary duties by failing to maximize shareholder value. On April 18, 2012, Catalyst and SXC announced that they had entered into a definitive merger agreement providing for SXC to acquire Catalyst in a cash and stock transaction valued at approximately $4.4 billion. Under the terms of the merger agreement, Catalyst shareholders will receive $28.00 in cash and 0.6606 shares of SXC stock for each Catalyst share, which implies a purchase price of $81.02 per Catalyst share.
