    SOUTH SAN FRANCISCO, Calif.--(BUSINESS WIRE)--Oct. 26,
2005--Actuate Corporation (Nasdaq:ACTU), the world leader in
Enterprise Reporting Applications, today announced financial results
for the third fiscal quarter ended September 30, 2005.
    Total revenues for the third quarter of 2005 were $26.8 million, a
13% increase compared with $23.8 million in the third quarter of 2004.
License revenues increased 11% to $8.9 million in the third quarter of
2005 from $8.0 million in the third quarter of 2004. Services revenues
increased 14% to $18.0 million in the third quarter of 2005 from $15.8
million in the third quarter of 2004. Operating margin on a GAAP basis
for the third quarter of 2005 was 17% and net profit margin on a GAAP
basis was 14%. Both operating margin and net profit margin were record
achievements for the Company. GAAP net income was $3.7 million, or
$0.06 per diluted share, for the third quarter of 2005 compared with a
GAAP net loss of $0.8 million or $0.01 per share in the third quarter
of 2004.
    Non-GAAP operating margin for the third quarter of 2005 was 18%
compared with a non-GAAP negative operating margin of 3% for the third
quarter of 2004. On a non-GAAP basis, net income in the third quarter
of 2005 was $3.6 million, or $0.06 per diluted share, compared with a
non-GAAP net loss of $0.5 million, or $0.01 per share in the third
quarter of 2004. These non-GAAP financial measures exclude the
amortization of purchased technology and other intangibles, unrealized
investment loss, restructuring costs and an adjustment to the tax
provision. All of these expenses are included in Actuate's GAAP
results. The income tax rate used to compute third quarter 2005
non-GAAP net income was 30%, compared with an income tax rate of 37.5%
used to compute second quarter 2005 non-GAAP net income.
    Cash, cash equivalents and short-term investments as of September
30, 2005 totaled $50.8 million, an increase of $1.5 million from June
30, 2005. Accounts receivable of $20.6 million at September 30, 2005
represented 70 days sales outstanding, an improvement from 76 days
sales outstanding at June 30, 2005. Deferred revenue at September 30,
2005 was $27.5 million, a decrease of $0.3 million compared with $27.8
million at June 30, 2005.
    "The third quarter extended our streak of year-over-year earnings
growth as we continue to execute our strategic initiatives for 2005,"
said Pete Cittadini, Actuate's president and CEO. "Our relentless
focus on customer success has resulted in a loyal base of Global 9000
customers who continue to develop and deploy Enterprise Reporting
Applications to support key business processes. These customers form
the foundation for our profitable baseline business."
    "Financial Management and Customer Self Service applications
continue to gain strength with our customers currently initiating
numerous new projects," continued Cittadini. "An independent study by
Forrester Research found business and financial benefits that further
validate Actuate's contribution to efficient and cost saving
reporting, as well as customer support and satisfaction. The
enhancements included in Actuate 8 SP1 delivers significant
productivity gains for BI application developers that speed the time
to value for our customers."

    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 purchased technology and other
intangibles, unrealized investment loss, restructuring costs 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. 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.

(c) The provision for income taxes used in arriving at the non-GAAP

    income tax rate of 30% and 37.5% for fiscal years 2005 and 2004,
    respectively. The amount of provision for income taxes used in
    arriving at the non-GAAP net income does not necessarily reflect
    the actual or future expected provision for income taxes.
