ITEM 2.02 RESULTS OF OPERATIONS AND FINANCIAL CONDITIONS.

On February 17, 2009 Vitesse Semiconductor Corporation. (the "Company") issued a press release captioned "Vitesse Reports First Quarter Fiscal 2009 Financial Results", a copy of which is attached hereto as Exhibit 99.1 and is incorporated herein by reference.

As a result of adverse market conditions, the Company performed an interim impairment test on its existing goodwill and intangible assets during the first quarter of fiscal year 2009, in accordance with SFAS No. 142, "Goodwill and Other Intangible Assets." This analysis resulted in a pre-tax non-cash impairment charge of $191.4 million and is necessary to reduce the book value of the Company's goodwill to its estimated fair value in light of financial market conditions and the material decline in the market value of the Company's common stock in the first quarter of fiscal 2009. The impaired goodwill was associated with the Company's prior acquisitions. The Company does not expect that the non-cash charge will have an impact on its financial condition or affect its debt agreements.

Due principally to this non-cash impairment charge, the Company reported a loss from operations of $188.3 million for the first quarter of fiscal year 2009. Excluding the goodwill impairment charge, income from operations would have been $3.1 million, compared with an operating loss of $4.9 million for the first quarter of fiscal year 2008.

Net loss was $190.0 million, or $(0.84) per share, for the first quarter of fiscal year 2009. Excluding the goodwill impairment charge, ending income or net income would have been $1.5 million, or $0.00 per share, compared with net income of $1.5 million, or $0.00 per share, for the first quarter of fiscal year 2008.

As used herein and in the press release, the terms; "ending income excluding the goodwill impairment charge," "income from operations excluding the goodwill impairment charge," "net income excluding the impairment charge" and "earnings per share excluding the impairment charge" represent non-GAAP financial measures pursuant to Rule 101 of Regulation G as promulgated by the U.S. Securities and Exchange Commission. This non-GAAP financial information is provided to allow investors to more clearly evaluate operating performance and business trends. Management uses these non-GAAP measurements to review results excluding items that are not necessarily indicative of ongoing results.

The information in this Current Report on Form 8-K, including Exhibit 99.1 hereto, shall not be deemed "filed" for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to liability of that section. The information in this Current Report shall not be incorporated by reference into any filing or other document pursuant to the Securities Act of 1933, as amended, except as shall be expressly set forth by specific reference in such filing or document.
