Item 2.05. Costs Associated with Exit or Disposal Activities.

On August 21, 2007, the board of directors of Applied Micro Circuits Corporation (“the Company”) approved a restructuring plan to reorganize the Company’s operations and reduce its workforce. The plan, which was effective September 27, 2007, includes eliminating job redundancies and reducing the Company’s current workforce by approximately 4%. The Company expects to incur a charge of approximately $0.6 million to $0.9 million over the remainder of fiscal 2008 for employee severances. The effective dates of the terminations vary by employee and extend into the fourth quarter of fiscal 2008, therefore the anticipated reductions in operating expenses will be phased in gradually over the next two quarters. The Company anticipates that the restructuring plan will reduce ongoing operating expenses by approximately $2.8 million annually.

This current report on Form 8-K contains forward-looking statements, including, but not limited to, statements regarding the expected costs of the Company’s restructuring plan and the anticipated reduction of ongoing operating expenses to the Company as a result of the plan. These forward looking statements are only predictions based on current information and expectations and are subject to certain risks and uncertainties, including, but not limited to, the Company’s ability to implement the restructuring plan to the extent currently anticipated, possible changes in the size and components of the operating expense reductions, the impact of personnel reductions on product development efforts, the Company’s ability to project accurately cost savings and changes from the plan and general economic conditions. More information about potential factors that could affect the Company’s business and financial results is included in the “Risk Factors” set forth in the Company’s Annual Report on Form 10-K for the year ended March 31, 2007, and the Company’s other filings with the Securities and Exchange Commission. Actual results could differ materially, as a result of such factors, from those set forth in the forward- looking statements. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this current report on Form 8-K. All forward-looking statements are qualified in their entirety by this cautionary statement.
