20 Use of NON-GAAP Financial Information To supplement its condensed consolidated balance sheet and statement of operations and comprehensive loss, which are prepared and presented in accordance with U.S. generally accepted accounting principles (“GAAP”), Hyzon Motors Inc. reports EBITDA and Adjusted EBITDA which are non-GAAP financial measures. EBITDA is determined by taking net loss and adding interest, depreciation and amortization. Adjusted EBITDA is determined by taking EBITDA and adding non-cash stock-based compensation expense, change in fair value of private placement warrant liability, change in fair value of earnout liability, change in fair value of equity securities and other special items determined by management. We believe that these non-GAAP measures, viewed in addition to and not in lieu of our reported GAAP results, provides useful information to investors by providing a more focused measure of operating results, enhances the overall understanding of past financial performance and future prospects, and allows for greater transparency with respect to key metrics used by management in its financial and operational decision making. The non-GAAP measures presented herein may not be comparable to similarly titled measures presented by other companies. EBITDA and Adjusted EBITDA are non-GAAP financial measures, see “Non-GAAP Financial Measures” below for important information regarding these non-GAAP financial measures.
