COPYRIGHT, DISCLAIMER, AND CONFIDENTIALITY Financial Information; Non-GAAP Financial Terms: The financial information and data contained in this presentation is unaudited and does not conform to Regulation S-X promulgated by the Securities and Exchange Commission ("SEC"). Accordingly, such information and data may not be included in, may be adjusted in, or may be presented differently in, any proxy statement/prospectus/consent solicitation statement or registration statement or other report or document to be filed by CleanTech with the SEC. Furthermore, some of the projected financial information and data contained in this presentation, such as adjusted EBITDA (and related measures), has not been prepared in accordance with U.S. generally accepted accounting principles ("GAAP"). Nauticus and CleanTech believe these non-GAAP measures of financial results provide useful information to management and investors regarding certain financial and business trends relating to Nauticus' financial condition and results of operations. Nauticus' management uses these non-GAAP measures for trends analyses and for budgeting and planning purposes. Nauticus and CleanTech believe that use of these non-GAAP measures provides an additional tool for investors to use in evaluating projected operating results and trends in and in comparing Nauticus' financial measures with other similar companies, many of which present similar non-GAAP financial measures to investors. Management of Nauticus does not consider these non-GAAP measures in isolation or as an alternative to financial measures determined in accordance with GAAP. The principal limitation of these non-GAAP financial measures is that they exclude significant expenses and income that are required by GAAP to be recorded in Nauticus' financial statements. In addition, they are subject to inherent limitations as they reflect the exercise of judgments by management about which expenses and income are excluded or included in determining these non-GAAP financial measures. You should review Nauticus' audited financial statements, which will be presented in CleanTech's proxy statement/prospectus/consent solicitation statement to be filed with the SEC, and not rely on any single financial measure to evaluate Nauticus' business. A reconciliation of non-GAAP financial measures in the presentation to the most directly comparable GAAP financial measures is not included because, without unreasonable effort, Nauticus is unable to predict with reasonable certainty the amount or timing of non-GAAP adjustments that are used to calculate these non-GAAP financial measures.
