“The results for our fourth quarter and fiscal year bring to a close one of the most challenging but successful years for Marvell,” said Dr. Sehat Sutardja, Marvell’s Chairman and Chief Executive Officer. “I am very pleased with the progress we have made over the previous 12 months, in the face of a turbulent global economy. During the past year, we have transformed our organization to improve the efficiency of product development, we have refined our business model to deliver world-class financial performance and we have laid the groundwork to accelerate our growth in the coming years. While I am proud of the progress we have made, we continue to be mindful of the challenging economic environment we operate within and the effect macro-economic events could potentially have on our business. Consequently, we will continue to focus on the aspects of our business we can control and influence. We believe it is important to aggressively invest in our employees and product development to allow Marvell to continue to deliver solutions that enable our customer’s success.”

Conference Call

Marvell will be conducting a conference call on March 4, 2010 at 1:45 p.m. Pacific Time to discuss results for the fourth fiscal quarter and fiscal year 2010. Interested parties may join the conference call by dialing 1-866-770-7120, pass-code 57220826. The call will be webcast by Thomson Reuters and can be accessed at the Marvell Investor Relations website at http://investor.marvell.com/ with a replay available following the call until April 4, 2010.

Discussion of Non-GAAP Financial Measures

Non-GAAP financial measures exclude stock-based compensation expense as well as charges related to acquisitions, restructuring, gains and other charges that are driven primarily by discrete events that management does not consider to be directly related to Marvell’s core operating performance. Non-GAAP earnings per share is calculated by dividing non-GAAP net income by non-GAAP weighted average shares outstanding (diluted). For purposes of calculating non-GAAP earnings per share, the GAAP weighted average shares outstanding (diluted) is adjusted to exclude the potential benefits of compensation costs expected to be incurred in future periods, but not yet recognized in the financial statements. The expected compensation costs are treated as proceeds assumed to be used to repurchase shares under the GAAP treasury stock method and also include the dilutive/antidilutive effects of common stock options and restricted stock.

Marvell believes that the presentation of non-GAAP financial measures provide important supplemental information to management and investors regarding financial and business trends relating to Marvell’s financial condition and results of operations. While Marvell uses non-GAAP financial measures as a tool to enhance its understanding of certain aspects of its financial performance, Marvell does not consider these measures to be a substitute for, or superior to, the information provided by GAAP financial measures. Consistent with this approach, Marvell believes that disclosing non-GAAP financial measures to the readers of its financial statements provides such readers with useful supplemental data that, while not a substitute for GAAP financial measures, allows for greater transparency in the review of its financial and operational performance. For further information regarding why Marvell believes that these non-GAAP measures provide useful information to investors, the specific manner in which management uses these measures, and some of the limitations associated with the use of these measures, please refer to Marvell’s Current Report on Form 8-K filed today with the SEC. The Form 8-K is available on the SEC’s website at www.sec.gov as well as on the Marvell website in the Investor Relations section at www.marvell.com.
