OPENWAVE REPORTS FIRST QUARTER FISCAL 2004 RESULTS

REDWOOD CITY, Calif. —October 28, 2003—Openwave Systems Inc. (Nasdaq: OPWVD), the leading provider of open software products and services for the communications industry, today announced that revenues for its first fiscal quarter ended September 30, 2003 were $68.0 million, an increase from $66.5 million for the preceding quarter ended June 30, 2003.

In addition to revenue, the Company delivered results at the high end of the range for management’s outlook with respect to gross margins, total ending cash and investments, earnings per share, and EBITDA.

“We continue to execute on our plan toward profitability,” said Don Listwin, president and CEO of Openwave. “Our optimism in the mobile data market is growing as operators worldwide are rolling out new services.”

Openwave effected a 1 for 3 reverse stock split on October 21. Per share net loss on a pre- and post-split basis are as follows:

Pre-Split

Based on Generally Accepted Accounting Principles (GAAP), net loss for the first quarter ended September 30, 2003 was $14.0 million or $0.08 per basic share pre-split, compared to a net loss of $25.7 million or $0.14 per basic pre-split share for the preceding quarter.

Post-Split

Based on GAAP, net loss for the first quarter ended September 30, 2003 was $14.0 million or $0.23 per basic post-split share, compared to a net loss of $25.7 million or $0.43 per basic post-split share for the preceding quarter.

EBITDA loss, which consists of earnings before interest, taxes, depreciation, amortization and impairment of assets including deferred stock-based compensation expense, was $4.7 million. EBITDA loss included restructuring-related charges of $1.9 million. The Company considers EBITDA to be an important measure of performance because it reflects the resources available to fund the Company’s operations, and it is an important metric often used by investors to evaluate the performance of a business.

As of September 30, 2003, the Company had cash, cash equivalents, short-term and long-term investments totaling $367.3 million, of which $29.9 million is set aside as restricted cash. The total cash includes $145.7 million of net proceeds that Openwave raised when it completed an issuance of convertible debt in September 2003. Net cash used for operating activities during the three months ended September 30, 2003 was $13.4 million, which includes $6.9 million of cash used for restructuring costs.

Second Quarter Fiscal 2004 Business Outlook

Management’s current outlook for the quarter ending December 31, 2003 is that revenues will be within a range of $65 million plus or minus 10 percent, gross profit will be between 71 and 74 percent of revenues, net loss between $5 million and $15 million, GAAP net loss per share between $0.09 and $0.25 per share, and EBITDA between positive $3 million and negative $6 million. Management expects to have cash, cash equivalents, short-term and long-term investments, inclusive of restricted cash, of $345 to $355 million as of December 31, 2003.
