VITRIA ANNOUNCES PRELIMINARY SECOND QUARTER
RESULTS FOR 2005

SUNNYVALE, Calif., July 7, 2005 — Vitria (Nasdaq:VITR), a leading provider of business process application solutions, today announced preliminary results for its second quarter ended June 30, 2005. These preliminary results are subject to completion of customary quarterly closing and review procedures by Vitria management and its independent auditors.

• Vitria expects revenue for the second quarter to be approximately $12 million, with license revenue expected to be approximately $2 million of that total.

• Based on this estimated revenue, Vitria expects a net loss for the quarter in the range of $6 to $7 million, or $0.18 to $0.20 per share.

• The second quarter will include a restructuring charge of approximately $900,000 related to employee severance costs.

• Vitria expects its cash, cash equivalents and short-term investments at the end of the second quarter to be approximately $68 million.

“We are disappointed with our financial results this quarter and in particular, our license revenues.” said Dale Skeen, founder and CEO of Vitria. “Several deals in the pipeline, including two enterprise license agreement (ELA) renewals that were expected to close during the quarter did not close. These results in the second quarter require us to take additional steps to lower the Company’s costs by, among other measures, trimming the company’s headcount by approximately 15% from the levels as of the end of the 1^st quarter. Over half of this reduction has already taken place, and the remainder will take place in the 3rd quarter, primarily through attrition.

Vitria will provide final second quarter 2005 financial results during its earnings conference call, which is scheduled for Wednesday, July 27, 2005 at 5:00 p.m. EDT/2:00 p.m. PDT. To listen, please dial one of the following numbers at least five minutes prior to the start of the call:
