Generally Accepted Accounting Principles (GAAP) Results

Net income for the third quarter of 2007, on a GAAP basis, was $1.3 million, or $0.03 per share (diluted), compared with a net loss of $0.1 million, or $0.00 per diluted share in the second quarter of 2007, and a net loss of $1.7 million, or $0.21 per share (diluted) in the third quarter of last year.

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. Non-GAAP financial measures in the third quarter of 2007 exclude $0.5 million in stock-based compensation expense and $0.2 million in amortization of acquired intangible assets. The reconciliation between GAAP and non-GAAP financial results are provided in the financial statements portion of this release.

Net income for the third quarter of 2007, on a non-GAAP basis, was $2.1 million, or $0.05 per share (diluted), compared with $1.0 million, or $0.03 per share (diluted) in the second quarter of 2007, and a net loss of $1.2 million, or $0.14 per share (diluted) in the third quarter of last year. Gross margins, on a non-GAAP basis, were 64.9% in the third quarter of 2007 compared to 65.2% in the second quarter of 2007 and 60.9% in the third quarter of last year.
