Levetown & Jenkins, LLP is conducting an investigation into alleged breaches of fiduciary duties and violations of state law by Applied Signal Technology, Inc. (“APSG”) (NASDAQ: APSG) and its Board of Directors in conjunction with the proposed buyout and acquisition of APSG by Raytheon Company (NYSE: RTN). Under the terms of a definitive merger agreement announced on December 20, 2010, APSG shareholders will receive $38.00 in cash for each share of APSG common stock they hold, with Raytheon offering an aggregate purchase price of approximately $490 million, net of cash acquired. The transaction is expected to close in early 2011.

The firm’s investigation concerns whether the proposed acquisition properly values APSG. Specifically, the investigation seeks to determine whether the APSG Board of Directors engaged in a fair process to obtain adequate consideration for all of the company's shareholders, whether the transaction undervalues the company to the detriment of its shareholders and, if so, the extent to which the company is undervalued in the proposed transaction.

The firm specializes in the representation of investors in shareholder and securities fraud class actions.
