Item 1.01 Entry into a Material Definitive Agreement.

On January 21, 2005, we entered into a Memorandum of Understanding (the “MOU”) containing the essential terms of a settlement of the securities class action entitled In re Applied Micro Circuits Corp. Securities Litigation, No. 01-CV-0649-RTB (AJB) (the “Action”), pending in the United States District Court for the Southern District of California (the “Court”) on behalf of the class representative Florida State Board of Administration and the members of the class certified on July 10, 2003 (collectively, the “Plaintiffs”), against us and our current and former officers and directors David Rickey, William Bendush, Thomas Tullie, Brent Little, Douglas Spreng, Vincent DeMaioribus, Stephen Smith, Roger Smullen, Sr., Greg Winner, Ram Sudireddy and Candace Kilburn (collectively, the “Defendants”).

Under the MOU, we agreed to pay $60,000,000 in cash (the “Settlement Fund”) in settlement of the Action within 10 business days following the Court’s preliminary approval of a definitive Stipulation of Settlement (the “Stipulation”). All costs of class notice and administration of the settlement, along with all fees and expenses awarded to Plaintiffs’ counsel, will be paid out of the Settlement Fund. We expect our insurance carriers to pay approximately $31,000,000 of the Settlement Fund.

In consideration for the payment of the Settlement Fund as described above, Plaintiffs agreed to dismiss with prejudice all known and unknown claims of any kind or nature that were asserted or that might or could have been asserted in the Action by any plaintiff against Defendants and their related parties arising out of or relating to the acquisition of our securities during the class period and the facts occurring through December 2001 that were or could have been alleged in the first amended consolidated complaint (the “Released Claims”) and to fully and completely release Defendants and their related parties from all Released Claims. The final judgment entered in the Action will forever bar all Released Claims against Defendants and their related parties. The Stipulation will also contain mutual releases of claims arising from the conduct of the litigation.

All parties agreed to cooperate in good faith to expeditiously prepare and execute the Stipulation and jointly seek court approval of the settlement as soon as practical. The settlement is conditioned upon final approval by the Court and a final judgment of dismissal with prejudice of the Action and on the release of all Released Claims as described above. If for any reason the settlement does not become final, or if the Stipulation is cancelled or terminated, contributions to the Settlement Fund will be returned to the parties who made them.

The foregoing summary of the MOU is qualified in its entirety by reference to the MOU, a copy of which is attached hereto as Exhibit 99.1 and is hereby incorporated by reference into this Item 1.01. A copy of the press release we issued with respect to the execution of the MOU is attached hereto as Exhibit 99.2 and is hereby incorporated by reference into this Item 1.01.

Caution Concerning Forward-Looking Statements

This Current Report on Form 8-K and the items incorporated by reference herein contain forward-looking statements, including, but not limited to, statements regarding the settlement and timing and magnitude of charges resulting from the settlement of the Action. 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 risk that the settlement will not be approved by the Court or that the charges resulting from the settlement will be higher than expected due to inability to obtain our insurers’ agreed upon contribution to the settlement or other reasons.

Item 2.02 Results of Operations and Financial Condition.

On January 21, 2005, we issued a press release in which we stated that we expect to record a charge of approximately $29,000,000 in the quarter ended December 31, 2004 in connection with the settlement of the litigation as more fully described under Item 1.01. A copy of the press release is attached hereto as Exhibit 99.2 and is hereby incorporated by reference into this Item 2.02.
