Management also uses non-GAAP measures to analyze and make operating decisions on the business. Earnings before interest, taxes, depreciation and amortization (“EBITDA”), Adjusted EBITDA, Adjusted net loss attributable to common stockholders and Adjusted net loss per share attributable to common stockholders are non-GAAP measures of operations and operating performance by the Company. These supplemental non-GAAP measures are provided to assist readers in assessing operating performance. Management believes EBITDA, Adjusted EBITDA, Adjusted net loss attributable to common stockholders and Adjusted net loss per share attributable to common stockholders are useful in assessing performance and highlighting trends on an overall basis. Management also believes these measures are used by companies in the fuel cell sector and by securities analysts and investors when comparing the results of the Company with those of other companies. EBITDA differs from the most comparable GAAP measure, net loss attributable to the Company, primarily because it does not include finance expense, income taxes and depreciation of property, plant and equipment and project assets. Adjusted EBITDA adjusts EBITDA for stock-based compensation, impairment and restructuring expenses, non-cash (gain) loss on derivative instruments and other unusual items, which are considered either non-cash or non-recurring. Adjusted net loss attributable to common stockholders and Adjusted net loss per share attributable to common stockholders differ from the most comparable GAAP measures, Net loss attributable to common stockholders and Net loss per share attributable to common stockholders, primarily because they do not include stock-based compensation, impairment and restructuring expenses, non-cash (gain) loss on derivative instruments and other unusual items, which are considered either non-cash or non-recurring. While management believes that these non-GAAP financial measures provide useful supplemental information to investors, there are limitations associated with the use of these measures. The measures are not prepared in accordance with GAAP and may not be directly comparable to similarly titled measures of other companies due to differences in the exact method of calculation. The Company’s non -GAAP financial measures are not meant to be considered in isolation or as a substitute for comparable GAAP financial measures and should be read only in conjunction with the Company’s consolidated financial statements prepared in accordance with GAAP. On the following slides, we calculate EBITDA and Adjusted EBITDA and reconcile these figures to the GAAP financial statement measure Net loss; we calculate Adjusted net loss attributable to common stockholders and reconcile that figure to the GAAP financial statement measure Net loss attributable to common stockholders; and we calculate Adjusted net loss per share attributable to common stockholders. |

These gains and losses are classified as Generation cost of sales. 4 The Company recorded a non-cash impairment expense of $1.3 million and $65.8 million for the three months and year ended October 31, 2025, respectively, related to the Company's prior investments in solid oxide technology, related Goodwill and in-process research and development intangible assets, property, plant and equipment, solid oxide inventory and purchase order commitments.
