SUNNYVALE, Calif., —October 25, 2007—Applied Micro Circuits Corporation [NASDAQ: AMCC] today reported its financial results for the second quarter of fiscal 2008.

Net revenues for the second quarter of fiscal 2008 were $58.2 million compared to $50.1 million reported in the first quarter of fiscal 2008 and $76.4 million reported in the second quarter of fiscal 2007. Revenues for the first six months were $108.3 million compared to $146.0 million for the comparable period last year.

The net loss on a generally accepted accounting principles (GAAP) basis for the second quarter of fiscal 2008 was $8.1 million or $(0.03) per share. The second quarter GAAP net loss compares with a net loss of $16.4 million or $(0.06) per share for the first quarter of fiscal 2008 and a net loss of $13.9 million or $(0.05) per share for the second quarter of fiscal 2007. Year to date the GAAP net loss was $24.5 million or $(0.09) per share compared to $14.7 million or $(0.05) per share for the first six months of fiscal year 2007.

The non-GAAP net loss for the second quarter of fiscal 2008 was $3.0 million or $(0.01) per share, compared to the non-GAAP net loss of $7.3 million or $(0.03) per share in the first quarter of fiscal 2008 and the non-GAAP net income of $10.4 million or $0.04 per share in the second quarter of fiscal 2007. Year to date the non-GAAP net loss was $10.3 million or $(0.04) per share compared to a non-GAAP net income of $18.5 million or $0.06 per share for the first six months of fiscal year 2007.

“I am pleased with our overall results. First, we achieved the revenue growth we were projecting and second, we saw a healthy increase in our backlog and order patterns. With the correction cycle now behind us, we are focused on further expanding our revenues and returning to non-GAAP profitability. We also entered a key new product cycle by shipping our SAS product family and we are very pleased with our customer traction,” said Kambiz Hooshmand, president and chief executive officer.

Bob Gargus, chief financial officer commented, “The second quarter was a challenge operationally as we put in place the planned initiatives to reduce operating expenses. With this now in place I anticipate that further revenue growth combined with reduced operating expenses will return us to non-GAAP profitability in the December quarter.”

AMCC reports its financial results in accordance with GAAP and also provides additional financial data that have not been prepared in accordance with GAAP. The non-GAAP results and other financial measures reported by the Company exclude certain items that are required by GAAP, such as restructuring charges, amortization of purchased intangibles, acquired in-process research and development, stock-based compensation charges, gains on sale of equity investment and renegotiated design tool agreement, payroll tax on certain stock option exercises and expenses related to stock option investigation. Expenses related to stock option investigation consist primarily of fees paid to professional service firms in connection with the Company’s internal investigation of historical stock option grant practices and the resulting restatement of the Company’s financial statements, the investigations by the Securities and Exchange Commission and the U.S. Attorney’s office arising from the internal investigation and the defense of derivative lawsuits arising from the Company’s internal investigation. Income taxes are adjusted to an estimated non-GAAP effective tax rate. These non-GAAP measures are not a substitute for GAAP measures and may not be consistent with the presentation used by other companies. The Company uses the non-GAAP financial measures to evaluate and manage its operations. The Company is providing this information to allow investors to perform additional financial analysis and because it is consistent with the financial models and estimates published by analysts who follow the Company. The attached schedule reconciles non-GAAP results and other financial measures reported by the Company with the most directly comparable GAAP financial measures.
