OPENWAVE REPORTS FOURTH QUARTER FINANCIAL RESULTS

REDWOOD CITY, CA – August 5, 2008 – Openwave Systems Inc. (Nasdaq: OPWV), one of the world’s leading software innovators enabling revenue-generating personalized services which converge the mobile and broadband experience, today announced that revenues for the fourth fiscal quarter ended June 30, 2008 were $53.5 million, compared with $47.0 million in the prior quarter ended March 31, 2008 and $61.0 million in the June quarter in the preceding year. Bookings for the quarter were $60.1 million.

Revenue of the recently divested client business, which was sold on June 27, 2008, and is included in discontinued operations, was $7.5 million for fiscal fourth quarter 2008, compared with $11.1 million in the prior quarter ended March 31, 2008 and $7.1 million in the same quarter in the preceding year.

“Despite a number of distractions that could have impacted our business, I am pleased with the quarter’s results and the positive resolution of several corporate activities, including the divestiture of our client asset, the appointment of a new CFO and the conclusion of our internal investigation and subsequent third quarter 10-Q filing,” said Bruce Coleman, interim CEO of Openwave. “As we enter into our new fiscal year, we are focusing our efforts on delivering new and innovative server side products to our tier one customers, as well as building a robust channel offering that complements our direct sales efforts and extends our customer base.”

On a GAAP basis, net income for the fourth fiscal quarter ended June 30, 2008 was $8.2 million, or $0.10 per share, compared with a net loss of $14.7 million, or $0.18 per share, in the prior quarter and a net loss of $123.8 million, or $1.50 per share, in the June quarter in the preceding year.

On a non-GAAP basis, net loss, which excludes discontinued operations, amortization of intangibles and other acquisition-related costs, stock-based

compensation, gains on sales of non-operating assets, costs associated with the stock option review, special investigation, and proxy contest, retention bonuses related to exploring strategic alternatives and restructuring costs, for the fourth fiscal quarter ended June 30, 2008 was $0.9 million, or $0.01 per share, compared with $7.2 million, or $0.09 per share, in the prior quarter and $11.2 million, or $0.14 per share, during the June quarter of the prior year. A reconciliation between net income (loss) on a GAAP basis and a non-GAAP basis is provided below in a table immediately following the Condensed Consolidated Statements of Operations.

Non-GAAP Measure

The Company’s stated results include a non-GAAP measure: non-GAAP net loss. Non-GAAP net loss excludes certain items since they are related to unique non-recurring events, such as gains on sales of non-operating assets, costs associated with the stock option review and proxy contest, and retention bonuses related to when the Company explored strategic alternatives. Additionally, non-GAAP net loss excludes other items since they are non-cash items that other companies often exclude, in order to compare the Company with other companies, such as stock-based compensation, and other expenses which management believes are of limited usefulness in evaluating the Company’s on-going business, such as restructuring costs and discontinued operations. Lastly, non-GAAP net loss excludes non-cash expenses that relate to non-routine events, such as the amortization of intangibles and acquisition-related costs. The company considers non-GAAP net loss to be an important measure because it provides a useful measure of the operational performance of the Company and is used by the Company’s management for that purpose. In addition, investors often use a measure such as this to evaluate the financial performance of a company. Non-GAAP net loss results are presented for supplemental informational purposes to facilitate understanding Openwave’s operating results. These non-GAAP results should not be considered as a substitute for financial information presented in accordance with generally accepted accounting principles, and may be different from non-GAAP measures used by other companies.
