NEW YORK, March 30, 2015 /PRNewswire/ -- Tripp Levy PLLC, a leading national securities and shareholder rights law firm, announces that it is investigating the acquisition of Catamaran Corp. (NASDAQ: "CTRX") (TSX: "CCT") ("Catamaran" or the "Company") on behalf of its shareholders. OptumRX will acquire all of Catamaran's outstanding common stock for $61.50 per share.

Our investigation has determined that the offer price of only $61.50 per share unfairly under-values the true going forward inherent value of Catamaran and that shareholders are not receiving the maximum value for their shares. Indeed, among other things, analysts have projected that Catamaran's stock is worth at least $66 per share. The investigation further seeks to determine whether senior management of Catamaran are acting in their own self-interests at the expense of shareholders. Mark Thierer, Catamaran's Chairman and CEO, will server as CEO of OptumRx, and Jeff Park, who servers as Catamaran's executive vice president, Operations, will become the COO of OptumRx.

If you are a shareholder of Catamaran and would like additional information as to how the acquisition may affect your rights as a shareholder, and how you may be eligible to obtain a higher price for your shares, please call us at no cost at:
