Management Comments

Mr. Ronnie Kenneth, Chairman and CEO of Voltaire commented, “During the fourth quarter of 2009, we continued to present a strong business and financial performance, ending the year with over $50 million in revenues, and a return to non–GAAP profitability in the fourth quarter.”

Mr. Kenneth added, “Throughout 2009, Voltaire focused on the long-term, by strengthening its core business fundamentals to position the Company to capitalize on current data center trends. During the year, we forged new server OEM partnerships, enhancing our presence in existing and new verticals, as well as expanded our geographic presence in Asia, where we are witnessing growing demand for our solutions. Furthermore, we built out our product portfolio, introducing several new products, and we enter 2010 with an end-to-end portfolio of switching products and first-in-kind application acceleration and management software that strongly differentiates Voltaire. As a result, Voltaire presented three consecutive quarters of growth, ending the year with a healthy pipeline.”

“Looking ahead, I believe 2010 will be an inflection point for Voltaire and our markets. The principles used in high performance computing of scale-out, low latency and application acceleration is becoming the foundation for next generation, virtualized data centers and the rapidly expanding cloud computing opportunity. We believe that we are well-positioned at the forefront of a coming widespread infrastructure refresh in the data center. We aim to capitalize on this potential and I am excited about the opportunities that lie ahead for Voltaire in the coming months and years.”

“I would like to take this opportunity to thank Kevin Kilroy, a director of Voltaire’s Board since January 2002, who resigned from the Board for personal reasons effective January 1, 2010, for his significant contribution to the Company over the years,” added Mr. Kenneth.

Outlook

Management introduces guidance for the full year of 2010.

Management expects that revenues for the full year of 2010 to be in range of $66 - $69 million, reflecting year over year revenue growth of 31 – 37% with the second half of the year, as usual, being seasonally stronger than the first.

Full year gross margin is expected to be in the range of 51-53%, similar to 2009. Gross margin in the second half of the year is expected to be higher than the first half of the year.

Non-GAAP operating expenses are expected to increase by up to 15% to between $38-39.5 million in 2010. In 2009, the Company embarked on deep cost cutting in order to weather the global economic crisis. The increase in operating expenses in 2010 is in order to enable the Company to fully capitalize on the current and emerging market opportunities, as well as support the accelerated forecasted growth of both the InfiniBand and Ethernet-based product lines. The Company targets a sustainable non-GAAP operating profit by Q4 2010.
