Non-GAAP Financial Measures

This press release contains the following non-GAAP financial measures: Non-GAAP Net Income, Non-GAAP Net Income Per Share, Billings, Adjusted EBITDA, Free Cash Flow, Non-GAAP Gross Profit and Non-GAAP Operating Expense.

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 net income excludes stock-based compensation, amortization of intangible assets related to acquisitions, restructuring charges, asset impairment charges, non-cash interest expense, other special items as identified by management and described elsewhere in this press release, and the impact of non-GAAP tax rate to income tax expense, which approximates our tax rate excluding discrete items and other specific events that can fluctuate from period to period.

Non-GAAP diluted common shares includes the diluted weighted average shares outstanding per GAAP regardless of whether the Company is in a loss position.

Billings consists of total revenue plus the change in deferred revenue, excluding deferred revenue from acquisitions.

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.

Free cash flow consists of cash flow from operations less capital expenditures.

Non-GAAP gross profit represents gross profit adjusted for stock-based compensation expense, restructuring expense and other special items as identified by management and described elsewhere in this press release.

Non-GAAP operating expense represents operating expense excluding stock-based compensation expense, amortization, restructuring charges, asset impairment charges and other special items as identified by management and described elsewhere in this press release.

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.

Change in Classification of Indirect Costs

Beginning in the first quarter of 2023, the Company refined its classification of certain indirect costs to reflect the way management is now reviewing the information in decision making and to improve comparability with peers. These indirect costs include certain IT, facilities, and depreciation expenses that were previously reported primarily in General and administrative expense. These indirect costs have now been reclassified to Research and development, Sales and marketing, and General and administrative expenses based on global headcount. Management believes this refined methodology better reflects the nature of the costs and financial performance of the Company.

As a result, the Company’s consolidated statements of operations have been recast for prior periods presented to reflect the effects of the changes to Research and development, Sales and marketing, and General and administrative expense. There was no net impact to total operating expenses, income from operations, net income or net income per share for any periods presented. The consolidated balance sheets, consolidated statements of comprehensive income, consolidated statements of changes in stockholders’ equity, and the consolidated statements of cash flows were not affected by changes in the presentation of these costs.

Each prior period that will be presented in the forthcoming Form 10-Q and Form 10-K filings will be recast to conform to current period presentation. The following tables provide the relevant financial results as previously reported, as recast for the current period and forthcoming filings, and the associated impacts of the changes. Within these tables, the references to periods such as “FY 2021” and “Q1 2022” refer to the corresponding periods as reported in the applicable Form 10-K, Form 10-Q, or Form 8-K filings.

The following table summarizes the changes made to the consolidated statements of operations (in thousands):
