Pomerantz Haudek Grossman & Gross LLP is investigating claims on behalf of investors of Tekelec (“Tekelec” or the “Company”) (NASDAQ:TKLC) concerning the proposed acquisition of Tekelec by a consortium led by Siris Capital Group, LLC. The cash transaction is valued at $780 million. The investigation concerns whether the board of directors are breaching their fiduciary duties by failing to adequately shop the Company and maximize shareholder value.

At least one analyst has set a target share price of $16.00.
