Management's Remaining 2009 Financial Outlook

The Company is providing its 2009 revenue and earnings per share guidance below. The earnings per share guidance is provided on both a GAAP basis and a non-GAAP basis. Non-GAAP diluted earnings per share excludes charges for stock-based compensation, purchase accounting adjustments to deferred revenue and acquisition-related amortization of intangible assets.

Third Quarter 2009 Guidance

The Company currently expects the following for the quarter ending September 30, 2009:

• GAAP revenue in the range of $123.4 - $129.4 million
• Non-GAAP revenue in the range of $124 - $130 million
• GAAP diluted earnings per share of $0.27 - $0.31
• Non-GAAP diluted earnings per share of $0.40 - $0.42

Fiscal Year 2009 Guidance

The Company currently expects the following for the fiscal year ending December 31, 2009:

• GAAP revenue in the range of $501.9 - $519.9 million
• Non-GAAP revenue in the range of $510 - 528 million
• GAAP diluted earnings per share of $1.13 - $1.26
• Non-GAAP diluted earnings per share of $1.66 - $1.76

The preceding third quarter 2009 guidance excludes non-recurring pre-tax charges of approximately $3.2 - $4.5 million associated with continued headcount right-sizing initiatives that management estimates will be substantially finalized during the third quarter. The fiscal year 2009 guidance excludes non-recurring pre-tax charges of approximately $4.5 - $5.8 million related to these activities, $1.3 million of which was recorded in the 2009 second quarter.

These statements are forward-looking and actual results may differ materially. ANSYS is unable to predict the likely duration and severity of the current disruption in the domestic and global economies. Should these economic conditions continue to deteriorate further, it could result in ANSYS not meeting the guidance provided above and ANSYS’ operating results and financial performance could be adversely affected. Non-GAAP diluted earnings per share and Non-GAAP revenue are supplemental financial measures and should not be considered as a substitute for, or superior to, diluted earnings per share or revenue determined in accordance with GAAP.
