Non-GAAP Financial Measures
This press release contains the following non-GAAP financial measures: Non-GAAP Software Product Revenue, Non-GAAP Total Revenue, Adjusted EBITDA, Modified Adjusted EBITDA, Non-GAAP Net Income, Non-GAAP Net Income Per Share and Free Cash Flow.

Altair believes that these non-GAAP measures of financial results provide useful information to management and investors regarding certain financial and business trends relating to its financial condition and results of operations. The Company’s management uses these non-GAAP measures to compare the Company’s performance to that of prior periods for trend analysis, for purposes of determining executive and senior management incentive compensation and for budgeting and planning purposes. The Company also believes that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends and in comparing the Company’s financial measures with other software companies, many of which present similar non-GAAP financial measures to investors.

Non-GAAP software product revenue and Non-GAAP total revenue include revenue not recognized under GAAP due to acquisition accounting adjustments associated with the accounting for deferred revenue in significant business combinations.

Adjusted EBITDA represents net income adjusted for income tax expense, interest expense, interest income and other, depreciation and amortization, stock-based compensation expense, restructuring charges, asset impairment charges and other special items as identified by management and described elsewhere in this press release.

Modified Adjusted EBITDA represents Adjusted EBITDA adjusted for revenue not recognized under GAAP due to acquisition accounting adjustments associated with the accounting for deferred revenue in significant business combinations.

Non-GAAP net income excludes stock-based compensation, amortization of intangible assets related to acquisitions, revenue not recognized under GAAP due to acquisition accounting and special items as identified by management and described elsewhere in this press release.

Non-GAAP diluted common shares includes total outstanding shares plus outstanding equity awards under the Altair equity award plans.

Company management does not consider these non-GAAP measures in isolation or as an alternative to financial measures determined in accordance with GAAP. The principal limitation of these non-GAAP financial measures is that they exclude significant expenses and income that are required by GAAP to be recorded in the Company’s financial statements. In addition, they are subject to inherent limitations as they reflect the exercise of judgment by management about which expenses and income are excluded or included in determining these non-GAAP financial measures. Altair urges investors to review the reconciliation of its non-GAAP financial measures to the comparable GAAP financial measures, which it includes in press releases announcing quarterly financial results, including this press release, and not to rely on any single financial measure to evaluate the Company’s business.

Reconciliation tables of the most comparable GAAP financial measures to the non-GAAP financial measures used in this press release are included with the financial tables at the end of this release.
