    SOUTHPOINTE, Pa., Nov. 3 /PRNewswire-FirstCall/ -- ANSYS, Inc.

    Excluding acquisition-related amortization, ANSYS' third quarter adjusted
(non-GAAP) results include:

    -   An adjusted operating profit margin of 39.4% as compared to 35.1% for
        the third quarter of 2004; an adjusted operating profit margin of 38.8%
        as compared to 35.3% for the first nine months of 2004; and

    -   Adjusted diluted earnings per share of $0.35 as compared to $0.25 for
        the third quarter of 2004; and adjusted diluted earnings per share of
        $0.97 as compared to $0.73 for the nine-month period ended September 30,
        2004.

    Third Quarter 2005 Tax Benefit:

    The GAAP and adjusted results summarized above include a third quarter tax
benefit of $500,000 related to the completion and filing of the Company's 2004
federal and state tax returns. This benefit had the effect of increasing net
income by approximately $500,000 in the 2005 third quarter and year-to-date
results.

    "This quarter marked yet another period of strong revenue and earnings
growth for the Company," said ANSYS President and CEO Jim Cashman. "As a leader
in our industry, we remain focused on the overall direction and health of the
business. Looking ahead, our energy and resources will be dedicated to expanding
our global markets at a significant pace and striving to develop and deliver
innovative engineering simulation solutions to our customers."

    Mr. Cashman continued, "Our growth in the third quarter continued to be
spread across all major geographic regions and among a broad array of
industries. We believe that our success is a result of the mounting competitive
and market pressures that our customers and businesses, in general, are facing.
Our solutions enable customers who are driven to find new ways to create more
innovative, higher quality products, to deliver them to market faster and to
minimize development and warranty costs."

    During the third quarter of 2005, ANSYS repurchased approximately 115,000
shares at a total cost of $4.4 million. As of September 30, 2005, 2.0 million
shares remain authorized for repurchase under the Company's stock repurchase
program.



    The adjusted results highlighted above, and the adjusted estimates for 2005
discussed below, represent non-GAAP (Generally Accepted Accounting Principles)
financial measures. A reconciliation of these measures to the appropriate GAAP
measures, for the three months and nine months ended September 30, is included
in the condensed financial information included in this release.

    Adjustments to Reported GAAP Financial Results

     -   Acquisition-Related Amortization:

    As previously announced, the Company completed its acquisition of Century
Dynamics, Inc. in January 2005. In previous years, the Company also acquired
CFX, CADOE S.A. and ICEM CFD Engineering. These acquisitions have all been
accounted for as purchases, resulting in the recording of a significant amount
of identifiable intangible assets.

    ANSYS is providing, and has historically provided, its current quarter GAAP
results as well as financial results that have been adjusted for the impact of
acquisition-related amortization. The Company believes that these non-GAAP
measures supplement its consolidated GAAP financial statements as they provide a
consistent basis for comparison between quarters that are not influenced by
certain non-cash items and are therefore useful to investors in helping them to
better understand the Company's operating results. In certain instances, such as
when intangibles are acquired through business acquisitions or become fully
amortized, amortization expense associated with acquired intangibles also makes
period-to-period comparisons difficult because amortization expense may appear
in one period but not in the comparable period. Management uses these non-GAAP
financial measures internally to evaluate the Company's business performance;
however, these measures are not intended to supersede or replace the GAAP
results.

    Management's Remainder 2005 and Initial 2006 Outlook

    Based on anticipated revenues and expenditures for the remainder of 2005,
the Company currently projects that fourth quarter 2005 diluted earnings per
share, adjusted to exclude acquisition-related amortization, will be in the
range of $0.35 to $0.36 based on revenues of $40 to $42 million. The Company's
current outlook relative to 2005 fourth quarter GAAP diluted earnings per share
estimate will be in the range of $0.33 to $0.34.

    The Company currently projects that 2006 fiscal year adjusted diluted
earning per share will be in the range of $1.45 to $1.47 based on revenues of
$175 to $178 million. The preceding estimates do not reflect expenses associated
with employee stock options. The Company expects to begin recording stock option
expense effective January 1, 2006 in accordance with recent guidance issued by
the Securities and Exchange Commission.

    Adjusted diluted earnings per share is a supplemental non-GAAP financial
measure. Due to the ongoing implementation of Statement of Financial Accounting
Standards 123R and the uncertainties related to the magnitude of the Company's
equity-based compensation expense during fiscal 2006, we are not able to
estimate at this time the magnitude of the impact of equity-based compensation
expense on our adjusted diluted earnings per share for the 2006 fiscal year.
Adjusted diluted earnings per share should not be considered as a substitute for
net income per diluted share determined in accordance with GAAP.

    ANSYS will hold a conference call at 10:30 Eastern Time on November 3, 2005
to discuss third quarter results as well as to provide guidance regarding
business prospects. The dial in number is 800-811-8830 or 913-981-4904 and the
passcode is "ANSYS." A replay will be available until August 10, by dialing
888-203-1112 or 719-457-0820 and the passcode is "ANSYS" or "26797". The
conference call will be webcast live as well as archived and can be accessed,
along with other financial information, on ANSYS' website, located at

    Reconciliation of Non-GAAP Measures

    This earnings release contains non-GAAP financial measures. For purposes of
Regulation G, a non-GAAP financial measure is a numerical measure of a
registrant's historical or future financial performance, financial position or
cash flows that excludes amounts, or is subject to adjustments that have the
effect of excluding amounts, that are included in the most directly comparable
measure calculated and presented in accordance with GAAP in the statement of
income, balance sheet or statement of cash flows of the issuer; or includes
amounts, or is subject to adjustments that have the effect of including amounts,
that are excluded from the most directly comparable measure so calculated and
presented. In this regard, GAAP refers to generally accepted accounting
principles in the United States. Pursuant to the requirements of Regulation G,
the Company has provided a reconciliation of the adjusted (non- GAAP) financial
measures to the most directly comparable GAAP financial measures.



    Adjusted operating profit margin and adjusted diluted earnings per share are
discussed in this earnings release because management uses this information in
evaluating the results of the continuing operations of the business and believes
that this information provides the users of the financial statements a valuable
insight into the operating results. Additionally, management believes that it is
in the best interest of its investors to provide financial information that will
facilitate comparison of both historical and future results and allows greater
transparency to supplemental information used by management in its financial and
operational decision making. Management encourages investors to review the
reconciliations of the non-GAAP financial measures to the most directly
comparable GAAP measures that are provided within the financial information
attached to this news release.
