Industry and market data used in this Presentation have been obtained from third-party industry publications and sources as well as from research reports prepared for other purposes. Nuvve has not independently verified the data obtained from these sources and cannot assure you of the data's accuracy or completeness. This data is subject to change. In addition, this Presentation does not purport to be all-inclusive or to contain all of the information that may be required to make a full analysis of Nuvve. Viewers of this Presentation should each make their own evaluation of Nuvve and of the relevance and adequacy of the information and should make such other investigations as they deem necessary. Certain statements included in this Presentation that are not historical facts are forward-looking statements for purposes of the safe harbor provisions under the United States Private Securities Litigation Reform Act of 1995. Forward-looking statements generally are accompanied by words such as "believe," "may," "will," "estimate," "continue," "anticipate," "intend," "expect," "should," "would," "plan," "predict," "potential," "seem," "seek," "future," "outlook," "model," "target," "goal," and similar expressions, and are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words. Forward-looking statements include statements regarding estimates and forecasts of other financial and performance metrics and projections of market opportunities, as well as any other statements that are not related to present factors or current conditions or that are not purely historical. These statements are based on various assumptions, whether or not identified in this Presentation, and on the current expectations of Nuvve's management. These forward-looking statements are provided for illustrative purposes only and are not intended to serve as, and must not be relied on by, any investor as a guarantee, an assurance, a prediction or a definitive statement of fact or probability. Actual events and circumstances are difficult or impossible to predict and will differ from those expressed or implied by these forward-looking statements. Many actual events and circumstances are beyond the control of Nuvve. These forward-looking statements are subject to a number of risks and uncertainties, including changes in domestic and foreign business, market, financial, political and legal conditions; risks relating to the uncertainty of Nuvve's projected financial information; risks related to the organic and inorganic growth of Nuvve's business and the timing of expected business milestones; the effects of competition on Nuvve's future business; the ability of Nuvve to obtain any necessary additional financing in the future; and those factors discussed in documents filed by Nuvve with the Securities and Exchange Commission ("SEC"). If any of these risks materialize or Nuvve's management's assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements. There may be additional risks that presently are unknown to Nuvve or that Nuvve currently believes are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. In addition, forward-looking statements reflect Nuvve's expectations, plans or forecasts of future events and views as of the date of this Presentation. Nuvve anticipates that subsequent events and developments will cause Nuvve's assessments to change. However, while Nuvve may elect to update these forward-looking statements at some point in the future, Nuvve specifically disclaims any obligation to do so, except as required by law. These forward-looking statements should not be relied upon as representing Nuvve's assessments as of any date subsequent to the date of this Presentation. Accordingly, undue reliance should not be placed upon the forward-looking statements.
