              Actuate Reports Third Quarter 2004 Financial Results

     SOUTH SAN FRANCISCO, Calif.--(BUSINESS WIRE)--Oct. 28, 2004--Actuate
Corporation (NASDAQ:ACTU), the world leader in Enterprise Reporting
Applications, today announced its financial results for the quarter ended
September 30, 2004. Revenues for the third quarter of 2004 were $23.8 million,
compared with $25.9 million in Q3 2003. On a GAAP basis, Actuate's net loss in
the third quarter of 2004 was $848,000, or $0.01 per share, compared with a net
loss of $645,000 or $0.01 per share, reported in the same quarter a year ago. On
a non-GAAP basis, net loss in the third quarter of 2004 was $504,000, or $0.01
per share, compared to non-GAAP net income of $429,000 or $0.01 per diluted
share in Q3 2003. Non-GAAP financial measures discussed in this press release
exclude the amortization of intangibles and purchased technology, in-process
R&D, restructuring charges, amortization of deferred compensation, certain legal
and accounting fees and an adjustment to the tax provision. All of these
expenses are included in Actuate's GAAP results.
     For the nine months ending September 30, 2004, revenues totaled $77.3
million, compared to $77.0 million for the same period a year ago. GAAP net
income for the first nine months of 2004 was $70,000, or $0.00 per diluted
share, compared to a GAAP net loss of $3.3 million, or $0.06 per share, for the
same prior-year period. Non-GAAP net income for the first nine months of 2004
was $1.9 million, or $0.03 per diluted share, compared to $2.2 million, or $0.03
per diluted share, for the same prior-year period.
     Cash, cash equivalents and short-term investments ended the third quarter
at $48.0 million, net of $1.5 million in stock repurchases made during the third
quarter and $1.2 million of fixed asset additions, primarily related to a
financial systems implementation. Deferred revenue ended the quarter at $26.9
million, a slight increase from the $26.7 million reported in the quarter ended
June 30, 2004.
     "Although we are very disappointed with our Q3 performance, I continue to
be excited about Actuate's near- and long-term market opportunities," said Pete
Cittadini, Actuate's president and CEO. "Actuate remains the only company that
can demonstrate 100% adoption of Enterprise Reporting Applications that deliver
breakthrough corporate performance in key business processes such as financial
management and sales management. We also offer the only viable platform that
truly scales to meet the performance demands of extranet applications that
improve customer self-service. Our open source BIRT initiative will generate
tremendous awareness for Actuate among Java developers, thus enabling Actuate to
appeal to all key constituents among our prospects. These strategic initiatives,
combined with our growing off-shore capabilities in China, position Actuate to
deliver cost-effective solutions to our customers and therefore profitable
growth for our shareholders."

     Organizational Restructuring

     As announced earlier this month, Actuate has undertaken an
expense-reduction program currently designed to eliminate up to $10 million in
annual operating expenses. This program is expected to return the company to
non-GAAP profitability in Q4 2004. As a result, the Company expects to take a
restructuring charge in its fiscal fourth quarter of approximately $2.0 million
for employee severance and other related costs.

     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
other costs arising from acquisitions, 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.
