Company Posts 117% Revenue Growth; Organic Growth Exceeds 60%

OREM, UT, April 30, 2008 – Omniture, Inc. (NASDAQ:OMTR), a leading provider of online business optimization software, today announced results for its first quarter ending March 31, 2008. The Company’s results reflect the acquisition of Visual Sciences, Inc., which was completed on January 17, 2008, and include Visual Sciences operating results since that date.

In the first quarter of 2008, Omniture achieved record revenue of $63.2 million, an increase of 117% compared to revenue of $29.2 million reported for the same period a year ago and an increase of 47% compared to $43.1 million in the prior period. Non-GAAP revenue for the quarter was $69.6 million. The difference between GAAP and non-GAAP revenue reflects the revenue excluded from the GAAP results due to purchase accounting adjustments, which reduces deferred revenue to its fair value.

“We are proud of our team delivering on earlier than expected synergies in our acquisitions and the continued strength of our core business. The combination of these two items led to better than expected non-GAAP profitability for the quarter and increased guidance for our non-GAAP Q4 operating margin and full-year revenue,” stated Josh James, CEO and co-founder of Omniture. “As one of the largest SaaS companies in the world, Omniture is leveraging its leadership position in the marketplace and building an ecosystem in arguably the most exciting space.”

Omniture’s GAAP net loss was $12.9 million or $0.19 per diluted share in the first quarter of 2008 as compared to a net loss of $2.4 million or $0.05 per diluted share in the first quarter of 2007. Non-GAAP net income was $7.3 million or $0.10 per diluted share for the first quarter 2008, compared to non-GAAP net income of $0.9 million or $0.02 per diluted share in the first quarter of 2007. Non-GAAP net income excludes the effect of the acquisition-related reduction to deferred revenue, stock-based compensation, amortization of certain intangible assets, imputed interest related to a patent license agreement and certain acquisition-related expenses and tax benefits.

First quarter fiscal 2008 adjusted EBITDA was $12.2 million. Adjusted EBITDA is defined as loss from operations on a GAAP basis less depreciation and amortization, stock-based compensation and the acquisition-related adjustment to deferred revenue.

During the first quarter of 2008, Omniture captured data from over 851 billion transactions and added over 250 new customers organically in addition to the new customers acquired in connection with the Visual Sciences acquisition. Following its acquisition of Visual Sciences, Omniture now has more than 4,500 customers worldwide. New customer relationships secured and announced in the first quarter include: American Cancer Society, Boingo Wireless, Burpee Seeds, Dominion Enterprises, Fox International Channels, HIT Entertainment, Jones Soda Company, Kia Motors, Nutrisystem, Rugs Direct, Sephora, Shopit, Sylvan Learning Centers, Ubid and Washington Post Newsweek Interactive. New international customers include: Cadbury Schweppes, FrenchConnection UK and Volkswagen Nutzfahrzeuge.

About Non-GAAP Financial Measures
In this release and during our conference call as described above we use or plan to discuss certain non-GAAP financial measures. Generally, a non-GAAP financial measure is a numerical measure of a company's performance, financial position or cash flows that either excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with generally accepted accounting principles in the United States of America, or GAAP. A reconciliation between non-GAAP and GAAP measures can be found in the accompanying tables and on the Investor Relations section of our corporate Web site at www.omtr.com. Non-GAAP financial measures should not be considered as a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP. These non-GAAP financial measures do not reflect a comprehensive system of accounting, differ from GAAP measures with the same captions and may differ from non-GAAP financial measures with the same or similar captions that are used by other companies.

We believe that, while these non-GAAP measures are not a substitute for GAAP results, they provide a basis for evaluating the company's operating results because they are helpful in understanding our past financial performance and our future results and facilitate comparisons of results between periods. We believe the calculation of non-GAAP revenue, which reflects the revenue excluded from the GAAP results due to purchase accounting adjustments to reduce deferred revenue to its fair value, provides a meaningful comparison to our historic GAAP revenue. We also believe the calculation of net income and loss, calculated without acquisition-related accounting adjustments to deferred revenue, stock-based compensation expense, the amortization of certain intangible assets, imputed interest expense and certain acquisition-related expenses and tax benefits, provides a meaningful comparison to our net loss figures. We also believe that adjusted EBITDA, which we calculate as loss from operations on a GAAP basis less depreciation and amortization, stock-based compensation and the acquisition-related adjustments to deferred revenue, is an indicator of the company's financial results and cash flows and is useful to investors in evaluating operating performance. Our management regularly uses these non-GAAP financial measures internally to understand, manage and evaluate our business and make operating decisions. These non-GAAP measures have been reconciled to the nearest GAAP measure as required under the rules and regulations promulgated by the U.S. Securities and Exchange Commission.
