    SOUTH SAN FRANCISCO, Calif.--(BUSINESS WIRE)--Feb. 10,
2005--Actuate Corporation (Nasdaq:ACTU), the world leader in
Enterprise Reporting Applications, today announced its financial
results for the quarter ended December 31, 2004. Revenues for the
fourth quarter of 2004 were $27.4 million, up 15% sequentially from
the third quarter of 2004 and consistent with the $27.4 million
recorded in Q4 2003. License revenues for the quarter were $10.9
million, an increase of 36% compared with $8.0 million in Q3 2004.
Fourth quarter 2004 GAAP net income was $1.2 million, or $0.02 per
diluted share, compared with a net loss of $1.2 million or $0.02 per
share in the year-ago quarter.
    Non-GAAP operating margin for the fourth quarter of 2004 was 13%
compared with a GAAP operating margin of 5% for the same period. On a

million, or $0.04 per diluted share, compared to non-GAAP net income
of $1.2 million, or $0.02 per diluted share in the year-ago quarter.
In connection with an expense-reduction initiative that was launched
in the fourth quarter of 2004, the company recorded a one-time
restructuring charge of $1.4 million. The non-GAAP financial results
discussed in this press release do not include this charge. These
non-GAAP financial measures also exclude the amortization of
intangibles and purchased technology, in-process R&D, 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 full fiscal year 2004, revenues totaled $104.7 million,
compared with $104.5 million in fiscal year 2003. GAAP net income for
fiscal year 2004 was $1.3 million, or $0.02 per diluted share,
compared with a GAAP net loss of $4.5 million, or $0.07 per share in
fiscal year 2003. Non-GAAP net income for fiscal year 2004 was $4.4
million, 31% greater than the $3.4 million of non-GAAP net income
reported for fiscal year 2003. Diluted non-GAAP net income per share
was $0.07 for fiscal year 2004 compared with $0.05 per diluted share
recorded in fiscal year 2003.
    Cash, cash equivalents and short-term investments ended fiscal
year 2004 at $47.3 million, an increase of $1.8 million compared with
the year ended December 31, 2003. Deferred revenue at December 31,
2004 was $28.8 million, compared with $25.8 million at December 31,
2003.

    Preliminary Results of Sarbanes-Oxley Section 404 Review

    During the course of the audit of Actuate Corporation's 2004
financial statements, KPMG identified a material weakness in internal
controls over financial reporting related to the Q4 2004 restructuring
charge. Specifically, a decision was made to vacate a foreign facility
and a liability aggregating $628,000 was recorded for costs to be
incurred for its remaining term. However, as of December 31, 2004, we
had not met all of the requirements under Financial Accounting
Standard 146 and, therefore, no liability should have been recorded.
The liability is now expected to be recorded in the first quarter of
2005. The restructuring charge was corrected prior to completion of
the audit and, as a result, did not have any effect on reported
year-end or previously reported financial results. Nevertheless,
Actuate is at this time uncertain whether KPMG will issue an adverse
opinion on the company's internal controls as a result of this
restructuring charge.
    Actuate Corporation will finalize its evaluation of internal
controls over financial reporting prior to the issuance of its Form
10-K for the year ended December 31, 2004. "Exclusive of this
instance, no other material weaknesses have been identified by
management or our auditors to date," said Dan Gaudreau, Chief
Financial Officer of Actuate Corporation. "Management continues to
take seriously its role in the design and effectiveness of internal
controls and will remediate all deficiencies in a timely manner."

    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, certain legal and
accounting 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.

    Actuate will be holding a conference call at 2:00 p.m. Pacific
Time, today, February 10, 2005 to further discuss these results. The
dial-in number for the call is 973-528-0008. The conference call will
