Item 2.02. Results of Operations and Financial Condition

On November 8, 2007, Vicor Corporation (the "Company") filed with the Securities and Exchange Commission a Form 12b-25 relating to an extension of the time to file its Quarterly Report on Form 10-Q for the quarter ended September 30, 2007. It also issued a press release announcing the need for an extension. In the Form 12b-25 and the press release, the Company said that certain financial information for a related party has been recently received, but the Company needs to complete its review of this information in order to record appropriate adjustments for the equity method of accounting in order to file the Quarterly Report on Form 10-Q for the quarter ended September 30, 2007. 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.

The full text of that press release is attached as Exhibit 99.1 hereto and incorporated by reference herein. The information furnished under this Item 2.02, including the Exhibit attached hereto, shall not be deemed "filed" for any purpose, including for purposes of Section 18 of the Securities and Exchange Act of 1934 (the "Exchange Act") or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933 or the Exchange Act, regardless of any general incorporation language in such filing.
