                Record Non-GAAP Operating Margin of 23%


    SAN MATEO, Calif.--(BUSINESS WIRE)--Oct. 29, 2007--Actuate
Corporation (NASDAQ:ACTU), the leader in Business Intelligence,
Performance Management and Reporting Applications, today announced its
financial results for the quarter ended September 30, 2007.

    License revenues for the third quarter of 2007 were $13.4 million,
a 16% increase from the year-ago quarter. Total revenues for the third
quarter of 2007 were $34.7 million, an increase of 9% compared with
the third quarter of 2006.

    Net income for the third quarter of 2007, as reported in
accordance with U.S. generally accepted accounting principles (GAAP),
was $4.6 million, or $0.07 per diluted share, an increase of 83%
compared with net income of $2.5 million or $0.04 per diluted share in
the third quarter of 2006.

    Non-GAAP operating margin for the third quarter of 2007 was 23%
compared with a non-GAAP operating margin of 18% for the third quarter
of 2006. Non-GAAP net income for the third quarter of 2007 was a
record $6.0 million, or $0.09 per diluted share, an increase of 35%
compared with non-GAAP net income of $4.5 million, or $0.07 per
diluted share in the third quarter of 2006.

    For the first nine months of 2007, revenues totaled a record
$101.4 million, an increase of 9% compared with the first nine months
of 2006. License revenues totaled $39.5 million, an increase of 21%
compared with the first nine months of 2006. For the first nine months
of 2007, GAAP operating income was a record $9.5 million, GAAP net
income was a record $9.4 million and GAAP diluted earnings per share
was a record $0.14. Non-GAAP net income for the first nine months of
2007 totaled a record $14.8 million, or $0.21 per diluted share, an
increase of 53% compared with non-GAAP net income of $9.7 million, or
$0.14 per diluted share reported for the first nine months of 2006.
For the first nine months of 2007, cash flow from operations was a
record $18.1 million, compared with $9.5 million for the first nine
months of 2006.

    Cash, cash equivalents and short-term investments at September 30,
2007 totaled $69.5 million, an increase of $9.4 million from December
31, 2006. This amount is net of a $14.2 million cash outlay during the
first nine months of 2007 in furtherance of Actuate's ongoing
open-market share repurchase program.

    "Actuate extended the number of consecutive quarters of double
digit year-over-year growth for both license revenue and non-GAAP net
income to seven in the third quarter," said Pete Cittadini, Actuate's
president and CEO. "Growth in license revenue continues to be fueled
by extranet customer self-service applications and intranet strategic
and operational performance management applications."

    "At the end of September, we launched BIRT Exchange
(www.birt-exchange.com), a dedicated resource for the Eclipse BIRT
developer community and the Actuate BIRT product line. BIRT Exchange
is gaining traction in terms of registered users and software
downloads including trial versions of commercial products."

    Discussion of Non-GAAP Financial Measures

    This press release contains financial measures that are not
calculated in accordance with U.S. generally accepted accounting
principles (GAAP). Actuate management evaluates and makes operating
decisions using various performance measures. In addition to our GAAP
results, we also consider adjusted net income, which we refer to as
non-GAAP net income. We further consider various components of
non-GAAP net income such as non-GAAP gross margin and non-GAAP
operating expense. Non-GAAP net income is generally based on the
revenues of our product, maintenance and services business operations
and the costs of those operations, such as cost of revenue, research
and development, sales and marketing and general and administrative
expenses, that management considers in evaluating our ongoing core
operating performance. Non-GAAP net income consists of net income
excluding amortization of intangible assets, merger and acquisition
charges, restructuring charges, equity plan-related compensation
expenses, duplicate rent on new corporate headquarters facilities and
charges and gains which management does not consider reflective of our
core operating business. Intangible assets consist primarily of
purchased technology, trade names, customer relationships, employment
agreements and other intangible assets issued in connection with
acquisitions. Merger and acquisition charges represent in-process
research and development charges related to products in development
that had not reached technological feasibility at the time of
acquisition. Restructuring charges consist of severance and benefits,
excess facilities and asset-related charges, and also include
strategic reallocations or reductions of personnel resources. Equity
plan-related compensation expenses represent the fair value of all
share-based payments to individuals, including grants of employee
stock options, as required under SFAS No. 123 (revised 2004),
"Share-Based Payment" (SFAS 123R). Duplicate rent expense represents
rent payments for the old headquarters that the Company has vacated
and the new headquarters that the Company has occupied. Management
does not consider these unusual expenses associated with a financial
transaction to be part of core operating performance. For purposes of
comparability across other periods and against other companies in our
industry, non-GAAP net income is adjusted by the amount of additional
taxes or tax benefit that the Company would accrue using a normalized
effective tax rate applied to the non-GAAP results.

    Non-GAAP net income is a supplemental measure of our performance
that is not required by, nor presented in accordance with, GAAP.
Moreover, it should not be considered as an alternative to net income,
operating income, or any other performance measure derived in
accordance with GAAP, or as an alternative to cash flow from operating
activities or as a measure of our liquidity. We present non-GAAP net
income because we consider it an important supplemental measure of our
performance.

    Management excludes from non-GAAP net income certain recurring
items to facilitate its review of the comparability of the Company's
core operating performance on a period to period basis because such
items are not related to the Company's ongoing core operating
performance as viewed by management. Management uses this view of its
operating performance for purposes of comparison with its business
plan and individual operating budgets and allocations of resources.
Additionally, when evaluating potential acquisitions, management
excludes the items described above from its consideration of target
performance and valuation. More specifically, management adjusts for
the excluded items for the following reasons:

    a) amortization charges for purchased technology and other
intangible assets related to the Company's acquisition transactions;
b) equity plan-related compensation expense; c) restructuring charges;
d) in-process research and development charges related to the
Company's acquisition transactions; e) duplicate rent expense, and f)
an adjustment to the income tax provision.

    The Company believes that, in general, these items possess one or
more of the following characteristics: their magnitude and timing is
largely outside of the Company's control; they are unrelated to the
ongoing operation of the business in the ordinary course; they are
unusual and the Company does not expect them to occur in the ordinary
course of business; or they are non-operational, or non-cash expenses
involving stock option grants.

    The Company believes that the presentation of these non-GAAP
financial measures is warranted for several reasons:

    1) Such non-GAAP financial measures provide an additional
analytical tool for understanding the Company's financial performance
by excluding the impact of items which may obscure trends in the core
operating performance of the business;

    2) Since the Company has historically reported non-GAAP results to
the investment community, the Company believes the inclusion of
non-GAAP numbers provides consistency and enhances investors' ability
to compare the Company's performance across financial reporting
periods;

    3) These non-GAAP financial measures are employed by the Company's
management in its own evaluation of performance and are utilized in
financial and operational decision making processes, such as budget
planning and forecasting;

    4) These non-GAAP financial measures facilitate comparisons to the
operating results of other companies in our industry, which use
similar financial measures to supplement their GAAP results, thus
enhancing the perspective of investors who wish to utilize such
comparisons in their analysis of the Company's performance.

    Set forth below are additional reasons why specific items are
excluded from the Company's non-GAAP financial measures:

    a) Amortization charges for purchased technology and other
intangible assets are excluded because they are inconsistent in amount
and frequency and are significantly impacted by the timing and
magnitude of the Company's acquisition transactions. We analyze and
measure our operating results without these charges when evaluating
our core performance. Generally, the impact of these charges to the
Company's net income tends to diminish over time following an
acquisition;

    b) While equity plan-related compensation calculated in accordance
with SFAS 123R constitutes an ongoing and recurring expense of the
Company, it is not an expense that typically requires or will require
cash settlement by the Company. We therefore exclude these charges for
purposes of evaluating our core performance as well as with respect to
evaluating any potential acquisition.

    c) Restructuring charges are primarily related to severance costs
and/or the disposition of excess facilities driven by modifications of
business strategy. These costs are excluded because they are
inherently variable in size, and are not specifically included in the
Company's annual operating plan and related budget due to the rapidly
changing facts and circumstances typically associated with such
modifications of business strategy;

    d) In-process research and development charges are excluded
because they are inconsistent in amount and frequency and are
significantly impacted by the timing and magnitude of the Company's
acquisition transactions. We analyze and measure our operating results
without these charges when evaluating our core performance.

    e) Duplicate rent expense is excluded because we have recognized
rent expense on both of our old and new corporate headquarters.
Accounting rules require that we recognize rent expense on our new
headquarters even though our landlord provides us with a rent holiday
for the period during the transition period to the new lease. We
therefore exclude the duplicate rent expense for purposes of
evaluating our core performance.

    f) Income tax expense is adjusted by the amount of additional
expense or benefit that we would accrue if we used non-GAAP results
instead of GAAP results in the calculation of our tax liability,
taking into consideration the Company's long-term tax structure. The
Company uses a normalized effective tax rate of 30%. This item is
excluded because the rate remains subject to change based on several
factors, including variations over time in the geographic business mix
and statutory tax rates.

    In the future, the Company expects to continue reporting non-GAAP
financial measures excluding items described above and the Company
expects to continue to incur expenses similar to the non-GAAP
adjustments described above. Accordingly, exclusion of these and other
similar items in our non-GAAP presentation should not be construed as
an inference that these costs are unusual, infrequent or
non-recurring.

    As stated above, the Company presents non-GAAP financial measures
because it considers them to be important supplemental measures of
performance. However, non-GAAP financial measures have limitations as
an analytical tool and should not be considered in isolation or as a
substitute for the Company's GAAP results. Some of the limitations in
relying on non-GAAP financial measures are:

    --  Amortization of intangibles, though not directly affecting our
        current cash position, represent the loss in value as the
        technology in our industry evolves, is advanced or is replaced
        over time. The expense associated with this loss in value is
        not included in the non-GAAP net income presentation and
        therefore does not reflect the full economic effect of the
        ongoing cost of maintaining our current technological position
        in our competitive industry which is addressed through our
        research and development program.

    --  The Company may engage in acquisition transactions in the
        future. Merger and acquisition related charges may therefore
        continue to be incurred and should not be viewed as
        non-recurring.

    --  The Company's stock option and stock purchase plans are
        important components of our incentive compensation
        arrangements and will be reflected as expenses in our GAAP
        results for the foreseeable future under SFAS 123R.

    --  The Company's income tax expense will be ultimately based on
        its GAAP taxable income and actual tax rates in effect, which
        may differ significantly from the 30% rate assumed in our
        non-GAAP presentation.

    --  Other companies, including other companies in our industry,
        may calculate non-GAAP financial measures differently than we
        do, limiting their usefulness as a comparative measure.

    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 is also available in the
investor relations section of the Company's web site at

consider this information strictly as a supplement to the GAAP results
that are contained in this press release and in the Company's SEC
filings.

(a) This table contains financial measures that are not calculated in
 accordance with U.S. generally accepted accounting principles (GAAP).
 Such measures are intended to serve as a supplement to the GAAP
 results presented elsewhere in this press release, and should not be
 considered in isolation or as a substitute for such GAAP results. See
 the section entitled Discussion of Non-GAAP Financial Measures in
 this press release for additional information regarding: the manner
 in which management uses these non-GAAP financial measures; the
 economic substance behind management's decision to use such measures;
 the material limitations associated with use of these non-GAAP
 financial measures as compared to the use of the most directly
 comparable GAAP financial measure; the manner in which management
 compensates for these limitations when using these non-GAAP financial
 measures; and the substantive reasons why management believes these
 non-GAAP financial measures provide useful information to investors.

(b) Amortization of purchased technology acquired in the
 Performancesoft and Nimble acquisition transactions in January of
 fiscal year 2006, and July of fiscal year 2003, respectively.
 Purchased technology is amortized over the estimated life of the
 underlying asset.

(c) Amortization of other intangibles includes identifiable intangible
 assets including trade names, employment agreements and customer
 relationships acquired through various acquisition transactions.
 Other identified intangibles are amortized over the estimated
 remaining life of the underlying intangibles.

(d) Prior to January 1, 2006, Actuate accounted for stock compensation
 under Accounting Principles Board, Opinion No. 25, "Accounting for
 Stock Issued to Employees" ("APB 25"). In accordance with APB 25,
 Actuate historically used the intrinsic value method to account for
 stock compensation expense. As of January 1, 2006 Actuate accounts
 for stock compensation expense under the fair value method. Actuate
 adopted the modified prospective transition method, results for prior
 periods have not been restated under the fair value method for GAAP
 purposes. Actuate is presenting a non-GAAP adjusted net income per
 diluted share financial measure which excludes stock based
 compensation expense for all periods presented. For the three months
 ended September 30, 2007, stock-based expense included approximately
 $288, $933, $419, and $879, related to cost of services revenues,
 sales and marketing expense, research and development expense, and
 general and administrative expense, respectively.

(e) We review our acquisitions to determine if there are any
 intangible assets relating to purchased in-process research and
 development. Projects that have not achieved technological
 feasibility and have no alternative future use are valued at fair
 market value using a discounted cash flow analysis and are expensed
 in the statement of operations on the date of acquisition.

(f) Fiscal 2007 costs were directly related to the relocation of our
 South San Francisco and Iselin, N.J. offices and consisted of early
 termination of facility leases.

(g) Duplicate rent expense is excluded because we have recognized rent
 expense on both of our old and new corporate headquarters. Accounting
 rules require that we recognize rent expense on our new headquarters
 even though our landlord provides us with a rent holiday for the
 period during the transition period to the new lease. We therefore
 exclude the duplicate rent expense for purposes of evaluating our
 core performance.

(h) Income tax expense is adjusted by the amount of additional expense
 or benefit that we would accrue if we used non-GAAP results instead
 of GAAP results in the calculation of our tax liability, taking into
 consideration the company's long-term tax structure. The Company uses
 a normalized effective tax rate of 30%. This item is excluded because
 the rate remains subject to change based on several factors,
 including variations over time in the geographic business mix and
 statutory tax rates.

(i) Shares used in calculating basic and diluted earnings per share
 have been adjusted to reflect what the share amounts would have been
 if they were calculated using non-GAAP results.
