Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On March 1, 2011, Applied Micro Circuits Corporation (the “Company”) announced that, effective February 24, 2011, Mr. H.K. Desai joined the Board of Directors of the Company (the “Board”). In connection with adding Mr. Desai as a Director of the Company, effective February 24, 2011, the size of the Board was increased from seven to eight members in accordance with the Bylaws of the Company. There is no arrangement or understanding between Mr. Desai and any other persons pursuant to which he was appointed as a Director of the Company.

Mr. Desai is chairman of the board of directors and executive chairman of QLogic Corporation (“QLogic”). From time to time, the Company has engaged in routine commercial transactions involving sales of various products to QLogic, both directly and indirectly through distributors, and a nonrecurring engineering payment. These transactions were entered into in the ordinary course of business on terms negotiated at arms-length. For the Company’s fiscal year ended March 31, 2010, QLogic made direct and indirect payments of approximately $2,025,000 to the Company. For the Company’s fiscal year ending March 31, 2011, as of February 28, 2011, QLogic has made direct and indirect payments of approximately $1,950,000 to the Company. Mr. Desai does not have, and has not had, any compensatory arrangements with either QLogic or the Company that relate specifically to the commercial transactions between QLogic and the Company.

Mr. Desai will receive compensation for his service as a director in accordance with the Company’s compensation policies for non-employee directors, which are described under “Executive Compensation — Director Compensation Policies and Processes” in the Company’s proxy statement filed with the Securities and Exchange Commission (the “SEC”) on July 7, 2010. Mr. Desai will also enter into an indemnification agreement with the Company; the form of the Company’s indemnification agreement for directors and officers was filed with the SEC as an exhibit to the Company’s registration statement on Form S-1 (No. 333-37609).
