Alternus Energy SPAC Presentation Deck

Disclaimer (Continued) Financial Information; Non-GAAP Financial Measures This Presentation includes certain financial measures not presented in accordance with generally accepted accounting principles ("GAAP") including, but not limited to, EBITDA and EBITDA Margin. These non-GAAP financial measures are not measures of financial performance in accordance with GAAP and may exclude items that are significant in understanding and assessing Alternus's financial results. Therefore, these measures should not be considered in isolation or as an alternative to net income, cash flows from operations or other measures of profitability, liquidity or performance under GAAP. You should be aware that the presentation of these measures may not be comparable to similarly-titled measures used by other companies. Clean Earth and Alternus believe these non-GAAP measures provide useful information to management and investors regarding certain financial and business trends relating to Alternus's financial condition and results of operations. Clean Earth and Alternus believe that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends in and in comparing Alternus's financial results with other similar companies, many of which present similar non-GAAP financial measures to investors. These non-GAAP financial measures are subject to inherent limitations as they reflect the exercise of judgments by management about which expense and income are excluded or included in determining these non-GAAP financial measures. This Presentation also includes certain projections of non-GAAP financial measures. Due to the high variability and difficulty in making accurate forecasts and projections of some of the information excluded from these projected measures, together with some of the excluded information not being ascertainable or accessible, Clean Earth and Alternus are unable to quantify certain amounts that would be required to be included in the most directly comparable GAAP financial measures without unreasonable effort. Consequently, no disclosure of estimated comparable GAAP measures is included and no reconciliation of the forward-looking non-GAAP financial measures is included. Certain monetary amounts, percentages and other figures included in this Presentation have been subject to rounding adjustments. Certain other amounts that appear in this Presentation may not sum due to rounding. Use of Projections This Presentation contains financial forecasts with respect to Clean Earth and Alternus's projected financial results, including Revenue, EBITDA and EBITDA Margin. Neither Clean Earth's nor Alternus's independent auditors have audited, reviewed, compiled or performed any procedures with respect to the projections for the purpose of their inclusion in this Presentation, and accordingly, they did not express an opinion or provide any other form of assurance with respect thereto for the purpose of this Presentation. These projections should not be relied upon as being necessarily indicative of future results. The assumptions and estimates underlying the prospective financial information are inherently uncertain and are subject to a wide variety of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the prospective financial information. Accordingly, there can be no assurance that the prospective results are indicative of the future performance of Alternus or that actual results will not differ materially from those presented in the prospective financial information. Inclusion of the prospective financial information in this Presentation should not be regarded as a representation by any person that the results contained in the prospective financial information will be achieved.
