Kirby McInerney LLP is investigating potential claims against the Board of Directors of TNS, Inc. (NYSE: TNS) related to the proposed acquisition of the Company by a group of investors led by Siris Capital Group. Under the terms of the agreement, Siris will acquire all outstanding shares of TNS for $21.00 per share in cash. The agreement values the company at approximately $862 million. The investigation concerns whether the TNS Board of Directors violated its fiduciary duties by agreeing to this transaction and whether the proposed $21.00 per share purchase price adequately values TNS common stock. The offer price represents a 44% premium to the closing price of shares on December 10, the day before the transaction was announced; however, shares were trading above the offer price as recently as April 30, 2012, and the average analyst price estimate for the stock is $27.50. If you are a TNS (NYSE: TNS) shareholder and wish to obtain additional information, please contact J. Brandon Walker, Esq. by email at firstname.lastname@example.org, or by telephone at (212) 699-1145 or (888) 529-4787.
