Former United States Securities and Exchange Commission attorney Willie Briscoe and the securities litigation firm of Powers Taylor, LLP are investigating the sale of Catalyst Health Solutions, Inc. (“Catalyst” or “CHSI”) (NASDAQ: CHSI) to SXC Health Solutions Corp. for shareholders. Under the proposed merger agreement, Catalyst shareholders will receive $28.00 in cash and 0.6606 shares of SXC stock for each share of Catalyst stock owned, which implies a purchase price of $81.02 per share. If you are an affected investor, and you want to learn more about the lawsuit or join the action, contact Patrick Powers at Powers Taylor, LLP, toll free (877) 728-9607, via e-mail at firstname.lastname@example.org, or Willie Briscoe at The Briscoe Law Firm, PLLC, (214) 706-9314, or via email at WBriscoe@TheBriscoeLawFirm.com. There is no cost or fee to you. The definitive merger agreement is a cash-and-stock transaction valued at approximately $4.4 billion. The transaction is expected to close in the second half of 2012. The investigation centers on whether Catalyst shareholders are receiving adequate compensation for their shares in the merger, whether the transaction undervalues Catalyst’s stock, and whether Catalyst’s board attempted to obtain the highest share price for all shareholders prior to agreeing to the deal. According to shareholder rights attorney Willie Briscoe, “Based on the lack of a significant premium to Catalyst shareholders, and other factors, the firms are investigating whether the buyout price is fair to Catalyst shareholders. Our proposed shareholder lawsuit seeks to obtain additional value for shareholders than what is proposed in the current buyout offer."
