NEW YORK, Dec. 13, 2013 /PRNewswire/ -- Pomerantz Grossman Hufford Dahlstrom & Gross LLP is investigating claims on behalf of investors of Performance Technologies, Inc. ("Performance Technologies" or the "Company") (NASDAQ: PTIX) (ISIN: US71376K1025) (CUSIP: 71376K102) concerning the proposed acquisition of Performance Technologies by Sonus Networks, Inc.

The investigation concerns whether the Performance Technologies directors are breaching their fiduciary duties by failing to adequately shop the Company and maximize shareholder value. Under the terms of the agreement, Performance Technologies shareholders will receive $3.75 per share in cash for each share of Performance Technologies common stock. However, the Price to Revenue and Total Assets multiples are below the averages of comparable transactions.

Performance Technologies shareholders seeking more information about this acquisition are advised to contact Robert Willoughby at rswilloughby@pomlaw.com or 212-661-1100 or 888-476-6529, ext. 237.
