Forward - looking statements include statements regarding estimates and forecasts of other financial and performance metrics and p rojections of market opportunity, 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 , w hether 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 m ust 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 dif fer 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 uncerta inties, including changes in domestic and foreign business, market, financial, political and legal conditions; failure to realize the anticipated benefits of the business combination with Newborn Acquisition Corp.; ri sks 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 competiti on on Nuvve’s future business; the ability of Nuvve to obtain any necessary additional financing in the future; and those factors discussed in Nuvve’s final prospectus dated February 16, 2021 under the heading “R isk Factors” and in the other documents filed, or to be filed, by Nuvve with the Securities and Exchange Commission (“SEC”). If any of these risks materialize or Nuvve’s management’s assumptions prove incorrect, actua l r esults 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 th at could also cause actual results to differ from those contained in the forward - looking statements.

Non - GAAP Financial Measures Some of the financial information and data contained in this Presentation has not been prepared in accordance with United Sta tes generally accepted accounting principles (“GAAP”).

Management does not consider these no n - 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 significa nt expenses and revenue that are required by GAAP to be recorded in Nuvve’s financial statements. In addition, they are subject to inherent limitations as they reflect the exercise of judgments by management abo ut which expense and revenue items are excluded or included in determining these non - GAAP financial measures. In order to compensate for these limitations, management presents historical non - GAAP financial measure s in connection with GAAP results. You should review Nuvve’s audited financial statements, which are included in Nuvve’s SEC filings.
