Non-GAAP Measure This presentation includes adjusted EBITDA. This non-GAAP measure provided herein is adjusted for certain items as presented in the Appendix of the 8k filed with this presentation containing the non-GAAP reconciliation. Forecasted adjusted EBITDA for 2024 is defined as operating income, as forecasted, plus stock-based compensation, plus depreciation and amortization. This non-GAAP measure is an indicator management uses as a basis for evaluating the Company’s performance and its ability to service debt and other finance obligations, as well as for forecasting future periods. Management also establishes performance targets, annual budgets and makes operating decisions based in part upon adjusted EBITDA. Disclosure of this non-GAAP measure provides investors with the same information that management uses for these purposes. In addition, investors have historically requested and the Company has historically reported this non-GAAP financial measure as a means of providing consistent and comparable information with past reports of financial results. Adjusted EBITDA is not a measure of our performance under GAAP and should not be considered in isolation or as an alternative to operating income or any other measures prepared in accordance with GAAP. While management believes that adjusted EBITDA provides useful supplemental information to investors, there are limitations associated with the use of this measure. Adjusted EBITDA is not prepared in accordance with GAAP and may not be directly comparable to a similarly titled measure of other companies due to potential differences in the exact method of calculation. Adjusted EBITDA should be read only in conjunction with the Company’s consolidated financial statements prepared in accordance with GAAP.
