Use of Non-GAAP Financial Measures

This press release contains “non-GAAP financial measures,” which are not based on a comprehensive set of accounting rules or principles.  This non-GAAP information supplements, and is not intended to represent a measure of performance in accordance with, disclosures required by generally accepted accounting principles, or GAAP.  Non-GAAP financial measures should be considered in addition to, not as a substitute for or superior to, financial measures determined in accordance with GAAP.  A reconciliation of GAAP to non-GAAP results is included in the financial tables included in this press release.

Management considers both GAAP and non-GAAP financial results in managing AspenTech’s business.  As the result of adoption of new licensing models, management believes that a number of AspenTech’s performance indicators based on GAAP, including revenue, gross profit, operating income and net income, should be viewed in conjunction with certain non-GAAP and other business measures in assessing AspenTech’s performance, growth and financial condition.  Accordingly, management utilizes a number of non-GAAP and other business metrics, including the non-GAAP metrics set forth in this press release, to track AspenTech’s business performance.  None of these non-GAAP metrics should be considered as an alternative to any measure of financial performance calculated in accordance with GAAP.
