MOUNTAIN VIEW, Calif., July 29, 2010 – Cavium Networks, Inc. (NASDAQ: CAVM), a leading provider of highly integrated semiconductor products that enable intelligent processing for networking, communications, and the digital home, today announced financial results for the second quarter of 2010 ended June 30, 2010.

Generally Accepted Accounting Principles (GAAP) Results
Net income for the second quarter of 2010, on a GAAP basis, was $0.6 million, or $0.01 per diluted share, compared to a net loss of $3.1 million, or $0.07 per diluted share in the first quarter of 2010, and a net loss of $6.2 million, or $0.15 per diluted share in the second quarter of last year. Gross margins were 60.8% in the second quarter of 2010 compared to 59.6% in the first quarter of 2010 and 46.8% in the second quarter of 2009. Total cash and cash equivalents were $69.0 million at June 30, 2010.

Non-GAAP Results
Cavium Networks believes that the presentation of non-GAAP financial measures provides important supplemental information to management and investors regarding financial and business trends relating to the company's financial condition and results of operations. These measures should only be used to evaluate the Company’s results of operations in conjunction with the corresponding GAAP measures. Non-GAAP financial measures in the second quarter of 2010 exclude expenses totaling $9.6 million related to stock-based compensation and related payroll expense, amortization of acquired intangible assets, acquisition related and other expenses. The reconciliation between GAAP and non-GAAP financial results is provided in the financial statements portion of this release.

Net income for the second quarter of 2010, on a non-GAAP basis, was $10.2 million, or $0.20 per diluted share, compared with non-GAAP net income of $6.9 million, or $0.14 per share in the first quarter of 2010. Gross margins, on a non-GAAP basis, were 64.4% in the second quarter of 2010 compared to 63.4% in the first quarter of 2010.

“Our record sales and strong sequential sales growth again came from strength across multiple markets. We had record bookings again this quarter. Furthermore, non-GAAP gross margins increased 100 basis points sequentially and operating margins increased 490 basis points sequentially, which shows the continued leverage in our business model.” said Syed Ali, president and CEO of Cavium Networks. “Design win traction was very strong, especially for recently introduced products including our Next Generation OCTEON™ II, PureVu and Econa family of processors.”
