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.
