    ANSYS President and CEO, Jim Cashman commented, "We are pleased to announce

double-digit revenue growth in all major geographies and continued strength in
our core business."

    Mr. Cashman continued, "Overall we are encouraged by what we have been able
to deliver in the first half of this year and remain optimistic about our
long-term business prospects. We believe that our performance underscores our
commitment to remaining customer focused and operationally disciplined to drive
results across multiple fronts. During the quarter, we also repurchased
approximately 92,000 shares of common stock in the open market, as we believe
this is a good use of capital and will enhance long-term shareholder value."

    Mr. Cashman concluded, "During this quarter, we continued to demonstrate
success and progress against our overall business plan as was evidenced by the
recent major releases of new and enhanced software products and the expansion of
customer and partner relationships. The repeat recognition of FORTUNE and
Business 2.0 is gratifying and a credit to the entire ANSYS team - including
dedicated employees, a network of valued partners and a loyal customer base -
who have helped us create a successful foundation to achieve leading-edge
technological and operational excellence as we continue to position ANSYS as a
preeminent global innovator of simulation software."

    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 six months ended June 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 2005 Outlook
    Based upon our first half results and our current visibility into revenues
and expenditures for the remainder of 2005, the Company currently projects that
full year revenue will grow in the 13 to 15% range and that 2005 diluted
earnings per share, adjusted to exclude acquisition-related amortization, will
be in the range of $1.23 to $1.25. The Company's current outlook relative to a
GAAP diluted earnings per share estimate will be in the range of $1.15 to $1.17.
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.

    ANSYS will hold a conference call at 10:30 Eastern Time on August 3, 2005 to
discuss second quarter results as well as to provide guidance regarding business
prospects. The dial in number is 800-289-0494 or 913-981-5520 and the passcode

    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

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.
