Vicor Corporation Announces Delay in Filing Form 10-Q


ANDOVER, MA--(Marketwire - August 9, 2007) - Vicor Corporation (NASDAQ: VICR) today announced that it will require an extension of time to file its Quarterly Report on Form 10-Q for the quarter ended June 30, 2007.

As noted in the Company's preliminary financial news brief dated July 30, 2007 and updated August 9, 2007, the Company's financial results for the second quarter ended June 30, 2007 are considered preliminary and subject to change based upon the final accounting for investments made by the Company in a related party entity. During Q2 2007, the Company made an additional investment of $1 million in the related party and agreed to a further investment of $1 million if certain conditions are met. The additional investment made in Q2 2007 requires the Company to account for the investment in the related party under the equity method of accounting and to retroactively restate its previously issued consolidated financial statements to reflect the equity method of accounting in prior periods. Certain financial information for the years ended December 31, 2003, 2004, 2005 and 2006 for the related party is not currently available to allow the Company to record the appropriate adjustments for the equity method of accounting in order to file the Quarterly Report on Form 10-Q for the quarter ended June 30, 2007 timely. In addition, the Company is performing additional valuation analyses to determine if any further adjustment in its investment is required due to other than temporary declines in value.
