"2007 was a major year for Voltaire in terms of growth and execution, laying strong foundations for future growth and performance in 2008 and beyond. This year we delivered on all of our financial and operational targets, reaching major new milestones. We introduced our Grid Director 20 Gigabits/second switches, became a public company, surpassed the $50 million annual revenue mark and achieved two consecutive quarters of profitability, while steadily increasing our profit margins," commented Ronnie Kenneth, Chairman and CEO of Voltaire. "Throughout the year we also continued to execute successfully our vertical market strategy and are seeing rapid adoption of Voltaire products in sectors outside of our traditional markets of government, research and education," added Mr. Kenneth. "Looking ahead to 2008, we intend to continue to build on these strong foundations, executing on our three core growth drivers - our vertical solutions approach, go-to-market strategy through our premier server OEM partners, and leading differentiated products, driving continued growth and execution in line with our long term business and financial model." Outlook Revenues for the first quarter of 2008 are expected to be in the range of $16 - $17 million, given seasonality, while earnings per share, on a non-GAAP basis, are expected to be around breakeven.
