Pomerantz Grossman Hufford Dahlstrom & Gross LLP is investigating claims on behalf of investors of TNS, Inc. (“TNS” or the “Company”) (NYSE: TNS) (ISIN: US8729601091) concerning the proposed acquisition of TNS, Inc. by an investor group led by Siris Capital Group in a transaction valued at approximately $862 million in cash. The investigation concerns whether the TNS directors are breaching their fiduciary duties by failing to adequately shop the Company and maximize shareholder value. Under the terms of the agreement, TNS shareholders will be entitled to receive $21.00 per share in cash for each share of TNS common stock. However, the price to revenue multiple for the Company is below comparable transactions, and at least one analyst targeted the price at $27.50 per share. TNS shareholders seeking more information about this acquisition are advised to contact Robert Willoughby at email@example.com or 212-661-1100 or 888-476-6529, ext. 237.
