San Francisco, CA, July 26, 2007 – Riverbed Technology, Inc. (Nasdaq: RVBD), the performance leader in wide-area data services (WDS), today released financial results for the second quarter ended June 30, 2007.

Revenues for the second quarter of 2007 were $54.0 million, which represents an increase of 199% from the second quarter of last year. Riverbed^® posted GAAP net income of $3.9 million, or $0.05 per diluted share, compared to a net loss of $6.1 million, or a loss of $0.46 per share, in the second quarter of 2006. Riverbed’s second quarter of 2007 GAAP results included $7.7 million of stock-based compensation expenses and related payroll taxes.

Excluding the impact of stock-based compensation and related payroll taxes in all periods, the non-GAAP net income for the second quarter of 2007 was $11.7 million, or $0.16 per diluted share, compared to a non-GAAP net loss of $4.6 million, or $0.09 per share, in the second quarter of 2006.

“Revenues increased by 26% quarter-over-quarter and 199% year-over-year as we continue to lead the rapidly growing wide-area data services (WDS) market and strengthen our competitive position,” noted Jerry Kennelly, Riverbed president and chief executive officer. “Our technological and market leadership is evident in our fast pace of customer acquisition, as we have won over 2,500 cumulative customers since we first introduced the Steelhead product line. In a separate press release today, we also announced the extension of our technology to the laptop with our Steelhead Mobile product, opening up a new market for the company targeting the hundreds of millions of remote and mobile office workers in the world today. Our innovation and focus allows us to continue to differentiate our company and our products in the WDS market we pioneered and lead in market share.”

“Strong revenue growth and solid margins led to a 35% increase in non-GAAP net income compared to the first quarter of 2007, even as we rapidly grew our headcount to facilitate anticipated future growth,” said Randy Gottfried, Riverbed chief financial officer. “During the quarter, we generated cash from operations of $14 million and ended the quarter with $218 million in cash and short term investments.”
