, which was primarily driven by increases in the fair value of our common stock warrant liability of $0.5 million, loss from divestiture of subsidiary of $0.1 million and a loss on disposal of fixed assets of $0.1 million for the year ended December 31, 2024. Non-GAAPfinancial measures We use certain non-GAAP financialmeasures to supplement our financial statements, which are presented in accordance with GAAP. These non-GAAP financialmeasures include EBITDA, Adjusted EBITDA, non-GAAPoperating loss, and non-GAAPnet loss. We use these non-GAAP financialmeasures for financial and operational decision-making and as a means to assist us in evaluating period-to-period comparisons.By excluding the impact of certain items that we believe do not directly reflect our underlying operations, we are of the opinion that EBITDA, Adjusted EBITDA, non-GAAPoperating loss and non-GAAPnet loss provide meaningful supplemental information regarding our performance. Accordingly, we believe these non-GAAP financialmeasures are useful to investors and others because they allow for additional information with respect to financial measures used by management in its financial and operational decision-making and forecasting. These 107

metrics also provide investors and other users of our financial information with additional tools to compare business performance across companies and periods, while eliminating the effects of items that may vary for different companies for reasons unrelated to core operating performance. However, there are a number of limitations related to the use of non-GAAP financialmeasures, and these non-GAAP measuresshould be considered in addition to, not as a substitute for or in isolation from, our financial results prepared in accordance with GAAP. Other companies, including companies in our industry, may calculate these non-GAAP financialmeasures differently or not at all, which reduces their usefulness as comparative measures. EBITDA We define EBITDA as net loss adjusted for income taxes, interest income, interest expense, and depreciation and amortization expense.
