Net income for the second quarter of 2009 calculated in accordance with U.S. generally accepted accounting principles (GAAP) was $3.4 million, or $0.06 per diluted share. In comparison, GAAP net income for the second quarter of 2008 was $0.9 million, or $0.02 per diluted share.

Non-GAAP net income for the second quarter of 2009 was $5.4 million or $0.10 per diluted share. In comparison, non-GAAP net income for the second quarter of 2008 was $3.6 million, or $0.06 per diluted share. Non-GAAP net income excludes amortization of purchased intangible assets, restructuring charges, and share-based compensation expense primarily associated with the expensing of stock options in accordance with Financial Accounting Standards No. 123R (FAS 123R). An explanation of our use of non-GAAP measures is included in the section in this press release entitled "Use of Non-GAAP Financial Measures."

The Company reported second quarter non-GAAP operating margin of 16%. In comparison, non-GAAP operating margin for the second quarter of 2008 was 7%. Non-GAAP gross margin in the second quarter was 74%, compared to 71% in the second quarter of 2008.

"Our commitment to operational excellence has served us well," said Matt Medeiros, CEO of SonicWALL. "We have continually made strong improvements in profitability and business efficiency while simultaneously keeping our focus on delivering an expanded array of solutions that are more competitive and relevant to the market."

Use of Non-GAAP Financial Measures

To supplement our consolidated financial statements presented in accordance with GAAP, SonicWALL uses non-GAAP measures of results of operations. These non-GAAP results are provided to enhance the user's overall understanding of our current financial performance and our prospects for the future. We believe the non-GAAP results provide useful information to both management and investors by excluding certain expenses. The non-GAAP measures are included to provide investors and management with an alternative method for assessing SonicWALL's operating results. In addition, since we have historically reported non-GAAP results to the investment community, we believe the inclusion of non-GAAP numbers provides consistency in our financial reporting. The presentation of this additional information should not be considered in isolation or as a substitute for results prepared in accordance with GAAP.
