Non-GAAP Financial Measure
To supplement our consolidated financial statements, which are prepared and presented in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”), we use adjusted earnings before interest, taxes, depreciation, and amortization (“Adjusted EBITDA”), a non-GAAP financial measure, to understand and evaluate our core operating performance. This non-GAAP financial measure, which may be different than similarly titled measures used by other companies, is presented to enhance investors’ overall understanding of our financial performance and should not be considered a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP.
We define our non-GAAP financial measure of Adjusted EBITDA as net loss, excluding income tax benefit, change in fair value of derivative liabilities, loss on extinguishment of Bridge Notes and Related Party Bridge Notes, gain on extinguishment of note payable, interest expense, depreciation and amortization, and share-based compensation expense.
