DALLAS – April 25, 2006 – Entrust, Inc. [Nasdaq: ENTU], a world leader in securing digital identities and information, today announced financial results for its fiscal quarter ended March 31, 2006.

Revenue for the first quarter was $21.1 million, a decrease of 15% from $24.9 million in Q1, 2005, and a decrease of 15% from $24.8 million in Q4, 2005. Product revenue for the first quarter was $6.6 million, a decrease of 18% from $8.1 million in Q1, 2005, and a decrease of 27% from $9.1 million in Q4, 2005.

Entrust recorded a Q1, 2006 net loss, calculated in accordance with GAAP, of $9.2 million, or $0.15 per share, compared to a Q1, 2005 net income of $1.0 million, or $0.02 per share, and Q4, 2005 net income of $3.4 million, or $0.05 per share. Entrust generated $3.2 million in cash flow from operations in Q1, 2006. Entrust also repurchased approximately 405 thousand shares in the quarter as part of its share repurchase program. The company ended Q1, 2006 with approximately $85 million in cash and marketable securities and no debt.

Entrust recorded a Q1, 2006 non-GAAP net loss of $2.7 million, or $0.04 per share, compared to Q1, 2005 non-GAAP net income of $1.1 million, or $0.02 per share, and Q4, 2005 non-GAAP net income of $3.5 million, or $0.06 per share. The Q1, 2006 non-GAAP net loss figure excludes amortization of purchased intangibles, stock-option based compensation, the write down of equity investments, and restructuring charges. See the financial table below reconciling non-GAAP adjustments to GAAP.

“We are disappointed in our quarterly financial results. Big deals were difficult to close for Entrust as also appeared to be the case across the security software market. However, our momentum in our emerging growth products continued. IdentityGuard, Entrust’s risk-based strong authentication platform, reached $1.0 million in product sales for Q1, its highest quarterly revenue to date,” said Entrust Chairman, President and CEO Bill Conner. “Entrust will continue to invest in sales, marketing, and research and development in our key growth segments which should allow us to grow product revenue roughly 10% year over year.”

Use of Non-GAAP Financial Measures

To supplement the financial results that are prepared and presented in accordance with accounting principles generally accepted in the United States, Entrust’s management prepares and uses non-GAAP financial measures for many of its internal financial, operating and planning reports. The Company’s management believes that by excluding charges such as the purchased intangibles amortization in cost of good sold, the amortization of intangible assets in operating expenses, stock option expenses, and restructuring charges from its GAAP-based results, these non-GAAP financial measures are more likely to facilitate investors’ understanding of the Company’s ongoing business operating results. These non-GAAP financial measures also facilitate comparisons to the operating results of the Company’s competitors and provide investors with greater transparency with respect to the supplemental information used by management in its operational and financial decision making.

The non-GAAP measures are included to provide investors with supplemental information to facilitate their understanding of Entrust’s operating results and future prospects. Management uses these non-GAAP measures to assess its success in reducing the Company’s cost structure, to measure its ongoing cash operating costs, and to establish budgets and operational goals. The presentation of this additional information should not be considered in isolation or as a substitute for financial and operating results prepared in accordance with accounting principles generally accepted in the United States, as non-GAAP measures are susceptible to varying calculations and they may not be comparable, as presented, to other similarly titled measures of other companies.

This press release contains forward-looking statements relating to Entrust’s projected revenue, net loss and net loss per share for the first quarter of 2006 and Entrust’s full year financial guidance. Such statements involve a number of risks and uncertainties. Among the important factors that could cause actual results to differ materially from those indicated by such forward-looking statements are unforeseen operating expenses, unconverted customer opportunities, issues associated with revenue recognition, issues raised in connection with the review of quarterly financial results, and the risk factors detailed from time to time in Entrust’s periodic reports and registration statements filed with the Securities and Exchange Commission, including without limitation Entrust’s Annual Report on Form 10-K for the fiscal year ended December 31, 2005. While Entrust may elect to update forward-looking statements in the future, Entrust specifically disclaims any obligation to do so, even if its estimates change.
