             Actuate Reports First Quarter 2004 Financial Results;
                     Achieves 6% Growth in License Revenues

    SOUTH SAN FRANCISCO, Calif.--(BUSINESS WIRE)--April 29,
2004--Actuate Corporation (Nasdaq:ACTU), the world leader in
Enterprise Reporting Applications, today announced its financial
results for the quarter ended March 31, 2004. Revenues for the first
quarter of 2004 were $25.7 million, an increase of $538,000 (2%)
compared with the first quarter of 2003. License revenues for the
first quarter of 2004 were $11.5 million, an increase of 6% compared
with the $10.9 million recorded in the first quarter of 2003.
    On a GAAP basis, Actuate's net loss in the first quarter of 2004
was $377,000, or $0.01 per share, an improvement of 55% compared with
a net loss of $836,000, or $0.01 per share, reported for the first
quarter of 2003. On a non-GAAP basis, Actuate's net income in the
first quarter of 2004 was $581,000, or $0.01 per diluted share.
    Non-GAAP financial measures discussed in this press release
exclude the amortization of intangibles and other costs arising from
acquisitions, certain legal and accounting fees, restructuring charges
and an adjustment to the tax provision. All of these expenses are
included in Actuate's GAAP results.
    "Actuate was founded ten years ago because we recognized the
astonishing long-term growth potential of the Enterprise Reporting
market," said Pete Cittadini, Actuate's president and CEO. "From the
outset, our guiding mission has been to understand the business
drivers and meet the technology requirements for Enterprise Reporting
better than anyone else. The depth and breadth of our experience boils
down to one guiding principle: technology solutions that deliver
decision-making information to enterprise users improve corporate
performance only when they are adopted by 100% of those users."

    Significant Q1 highlights for Actuate included the following:

    --  Added 80 new customers;

    --  Recorded a 6% increase in license revenues compared with Q1
        2003, the largest year-over-year percentage increase in over
        two years;

    --  Signed 57 transactions greater than $100,000, the highest
        number ever attained in any first fiscal quarter;

    --  Recorded one transaction greater than $1.0 million;

    --  Honored as "Technology Vendor of the Year" by KeyCorp, one of
        the largest U.S. bank-based financial services companies;

    --  Delivered initial support for Linux within the Enterprise

    During the first quarter of 2004, Actuate closed 80 new customers

    The non-GAAP financial measures discussed in the text of this
press release and accompanying non-GAAP supplemental information
represent financial measures used by Actuate's management to evaluate
the operating performance of the Company and to conduct its business
operations. Non-GAAP financial measures discussed in this press
release exclude the amortization of intangibles and other costs
arising from acquisitions, certain legal and accounting fees,
restructuring charges and an adjustment to the tax provision. It is
management's belief that these items are not indicative of ongoing
operations and as a result, non-GAAP financial measures that exclude
such items provide additional insight for investors in evaluating the
Company's financial and operational performance. However, these
non-GAAP financial measures are not intended to be an alternative to
financial measures prepared in accordance with GAAP. Pursuant to the
requirements of SEC Regulation G, a detailed reconciliation between
the Company's GAAP and non-GAAP financial results is provided in this
press release and investors are advised to carefully review and
consider this information as well as the GAAP financial results that
are disclosed in the Company's SEC filings. Additionally, the non-GAAP
reconciliation will be available in the investor relations section of
Actuate's website at www.actuate.com.
