         Revenues of $25.8 Million; GAAP EPS of $0.06; $2.0 Million in
      Cash Flow from Operations; Record Non-GAAP Operating Margin of 16.2%



    SOUTH SAN FRANCISCO, Calif.--(BUSINESS WIRE)--July 27,
2005--Actuate Corporation (NASDAQ:ACTU), the world leader in
Enterprise Reporting Applications, today announced financial results
for the quarter ended June 30, 2005.
    Total revenues for the second quarter of 2005 were $25.8 million,
a sequential increase compared with $24.6 million in the first quarter
of 2005. License revenues for the quarter were $8.8 million, compared
with $8.9 million in the first quarter of 2005. Services revenues
totaled $17.0 million for the second quarter of 2005, an increase of
$1.3 million compared with the $15.7 million reported in the first
quarter of 2005. Second quarter 2005 GAAP net income was $3.6 million,
or $0.06 per diluted share, compared with GAAP net income of $245,000
or $0.00 per diluted share in the first quarter of 2005.
    Non-GAAP operating margin for the second quarter of 2005 was 16.2%
compared with a non-GAAP operating margin of 6.0% for the first
quarter of 2005. On a non-GAAP basis, net income in the second quarter
of 2005 was $2.9 million, or $0.05 per diluted share, compared with
non-GAAP net income of $1.2 million, or $0.02 per diluted share in the
first quarter of 2005. These non-GAAP financial measures exclude the
amortization of intangibles and purchased technology, asset
impairment, amortization of deferred compensation, restructuring
costs, certain legal fees and an adjustment to the tax provision. All
of these expenses are included in Actuate's GAAP results.
    In the second quarter of 2005, Actuate's actual tax rate was 2.4%
compared to the historical non-GAAP tax rate of 37.5%, resulting in
non-GAAP net income that is lower than net income calculated in
accordance with GAAP.
    Cash, cash equivalents and short-term investments as of June 30,
2005 totaled $49.3 million, a decrease of $337,000 compared with March
31, 2005. Deferred revenue at June 30, 2005 was $27.8 million, a 6%
increase compared with $26.2 million at March 31, 2005.
    "In the second quarter, we continued to solidify our financial
infrastructure and make tangible progress toward our growth
initiatives -- successful performance that positions us squarely on
track to achieve the goals we set for ourselves last October," said
Pete Cittadini, Actuate's president and CEO. "We have posted
year-over-year earnings growth in each of the last three quarters, and
have generated cash flow from operations of $4.8 million year to
date."
    "Actuate had another strong quarter of orders from the Global 9000
Financial Services sector particularly with Financial Performance
Management and Customer Self-Service Enterprise Reporting Applications
that support key business processes in highly adoptable fashion,"
continued Cittadini. "In addition, our Open Source initiative
continues to fire on all cylinders, with the on-time June launch of
the BIRT project by the Eclipse Foundation and the simultaneous
release of our commercial Actuate BIRT offering."

    Use of Non-GAAP Financial Measures

    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 purchased
technology, asset impairment, amortization of deferred compensation,
restructuring costs, certain legal fees 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.

Time, today, July 27, 2005 to further discuss these results. The
