Conference Call Information

In light of the proposed transaction with Siemens, Altair is suspending quarterly financial results conference calls and its quarterly and annual guidance.

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, 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 is calculated using the treasury stock method to calculate the effect of dilutive securities, stock options, restricted stock units and employee stock purchase plan shares and using the if-converted method to calculate the effect of convertible instruments. This is the same methodology that is used when calculating GAAP diluted shares. However, the determination of whether the shares are dilutive or antidilutive is made independently on a GAAP and non-GAAP net income (loss) basis and therefore the number of diluted shares outstanding for GAAP and non-GAAP may be different.

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, 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 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, 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.

This communication contains “forward-looking statements” within the Private Securities Litigation Reform Act of 1995. Any statements contained in this communication that are not statements of historical fact, including statements regarding the proposed transaction, including the expected timing and closing of the proposed transaction; Altair’s ability to consummate the proposed transaction; the expected benefits of the proposed transaction and other considerations taken into account by the Altair Board of Directors in approving the proposed transaction; the amounts to be received by stockholders and expectations for Altair prior to and following the closing of the proposed transaction, may be deemed to be forward-looking statements. All such forward-looking statements are intended to provide management’s current expectations for the future of Altair based on current expectations and assumptions relating to Altair’s business, the economy and other future conditions.

Because forward-looking statements relate to the future, they are subject to inherent risks, uncertainties and changes in circumstances that are difficult to predict. Such risks and uncertainties include, among others: (i) the timing to consummate the proposed transaction, (ii) the risk that a condition of closing of the proposed transaction may not be satisfied or that the closing of the proposed transaction might otherwise not occur, (iii) the risk that a regulatory approval that may be required for the proposed transaction is not obtained or is obtained subject to conditions that are not anticipated, (iv) the diversion of management time on transaction-related issues, (v) risks related to disruption of management time from ongoing business operations due to the proposed transaction, (vi) the risk that any announcements relating to the proposed transaction could have adverse effects on the market price of the common stock of Altair, (vii) the risk that the proposed transaction and its announcement could have an adverse effect on the ability of Altair to retain customers and retain and hire key personnel and maintain relationships with its suppliers and customers, (viii) the occurrence of any event, change or other circumstance or condition that could give rise to the termination of the Merger Agreement, dated October 30, 2024, with Siemens (the “Merger Agreement”), including in circumstances requiring Altair to pay a termination fee, (ix) the risk that competing offers will be made; (x) unexpected costs, charges or expenses resulting from the merger, (xi) potential litigation relating to the merger that could be instituted against the parties to the Merger Agreement or their respective directors, managers or officers, including the effects of any outcomes related thereto, (xii) worldwide economic or political changes that affect the markets that Altair’s businesses serve which could have an effect on demand for Altair’s products and impact Altair’s profitability and (xiii) disruptions in the global credit and financial markets, including diminished liquidity and credit availability, changes in international trade agreements, including tariffs and trade restrictions, cyber-security vulnerabilities, foreign currency volatility, swings in consumer confidence and spending, raw material pricing and supply issues, retention of key employees, increases in fuel prices, and outcomes of legal proceedings, claims and investigations. Accordingly, actual results may differ materially from those contemplated by these forward-looking statements. Investors, therefore, are cautioned against relying on any of these forward-looking statements. They are neither statements of historical fact nor guarantees or assurances of future performance. Additional information regarding the factors that may cause actual results to differ materially from these forward-looking statements is available in Altair’s filings with the SEC, including the risks and uncertainties identified in Part I, Item 1A – Risk Factors of Altair’s Annual Report on Form 10-K for the year ended December 31, 2023 and in Altair’s other filings with the SEC.
