Levetown & Jenkins, LLP Announces Investigation into Acquisition of Keithley Instruments Inc. by Danaher Corporation

Levetown & Jenkins, LLP is conducting an investigation into alleged breaches of fiduciary duties and violations of state law by Keithley Instruments Inc. (“Keithley”) (NYSE:KEI) and its Board of Directors in conjunction with the proposed sale of Keithley to Danaher Corporation. Under the terms of the proposed transaction, Keithley shareholders will receive only $21.60 in cash for each share they own. The transaction is valued at approximately $300 million and is expected to be completed during the fourth quarter of 2010.

The firm’s investigation concerns whether the proposed transaction properly values Keithley. Specifically, the investigation seeks to determine whether the Keithley 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.
