Item 2.02. Results of Operation and Financial Condition.

On April 26, 2006, Applied Micro Circuits Corporation (“AMCC”) issued a press release regarding its financial results for the fourth quarter ended March 31, 2006. A copy of the press release is furnished as Exhibit 99.1 to this Current Report.

AMCC reports its financial results in accordance with GAAP and additionally provides supplemental financial data on a non-GAAP basis. These non-GAAP measures are not in accordance with, nor are they a substitute for, GAAP measures and they may not be consistent with the presentation used by other companies. AMCC’s management believes non-GAAP financial data is a useful measure that facilitates evaluating the ongoing performance of AMCC operations on a comparable basis. AMCC uses non-GAAP financial data to internally evaluate and manage our operating performance and in formulating our budget for future periods. AMCC is providing this information to investors and analysts, who may wish to use some or all of this information to analyze our current performance and because it is consistent with the financial models and estimates published by analysts who follow the Company.

The information in this Item 2.02 and Exhibit 99.1 is being furnished and shall not be deemed “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934 or otherwise subject to the liabilities of that Section. The information in this Current Report shall not be incorporated by reference into any registration statement or other document filed with the Commission.
