Other expense, net increased $0.7 million, or 159%, for the year ended December 31, 2024 compared to the year ended December 31, 2023, 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-GAAPfinancial measures to supplement our financial statements, which are presented in accordance with GAAP. These non-GAAPfinancial measures include EBITDA, Adjusted EBITDA, non-GAAPoperating loss, and non-GAAPnet loss. We use these non-GAAPfinancial measures for financial and operational decision-making and as a means to assist us in evaluating period-to-periodcomparisons. 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-GAAPfinancial measures 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 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-GAAPfinancial measures, and these non-GAAPmeasures should 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-GAAPfinancial measures differently or not at all, which reduces their usefulness as comparative measures. E
