Nuvve SPAC Presentation Deck

Legal Disclaimer (cont.) Financial Information; Non-GAAP Financial Measures The financial information and data contained in this Presentation is unaudited and does not conform to Regulation S-X. Accordingly, such information and data may not be included in, may be adjusted in or may be presented differently in, any proxy statement/prospectus or registration statement to be filed by NBAC with the SEC, and such differences may be material. In particular, all Nuvve historical financial information included herein is preliminary and subject to change pending finalization of the audits of Nuvve for the years ended December 31, 2019 and December 31, 2018 in accordance with PCAOB auditing standards. Some of the financial information and data contained in this Presentation has not been prepared in accordance with United States generally accepted accounting principles ("GAAP"). NBAC and Nuvve believe that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating historical or projected operating results and trends in and in comparing Nuvve's financial measures with other similar companies, many of which present similar non-GAAP financial measures to investors. Management 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 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 about 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 measures in connection with GAAP results. You should review Nuvve's audited financial statements, which will be included in the Proxy Statement (as defined below). However, not all of the information necessary for a quantitative reconciliation of the forward-looking non-GAAP financial measures to the most directly comparable GAAP financial measures is available without unreasonable efforts at this time. Important Information About the Proposed Business Combination and Where to Find It In connection with the Proposed Business Combination, a subsidiary of NBAC intends to file a registration statement with the SEC, which will include a proxy statement/prospectus (the "Proxy Statement/Prospectus") to be distributed to holders of NBAC's ordinary shares in connection with NBAC's solicitation of proxies for the vote by NBAC's shareholders with respect to the Proposed Business Combination and other matters as described in the Proxy Statement/Prospectus, as well as to the holders of NBAC's and Nuvve's securities in connection with offer of the subsidiary's securities to such holders. NBAC will mail a definitive proxy statement/prospectus, when available, to its shareholders. INVESTORS AND SECURITY HOLDERS ARE URGED TO READ THE PROXY STATEMENT/PROSPECTUS, ANY AMENDMENTS THERETO AND ANY OTHER DOCUMENTS FILED WITH THE SEC CAREFULLY AND IN THEIR ENTIRETY WHEN THEY BECOME AVAILABLE BECAUSE THEY WILL CONTAIN IMPORTANT INFORMATION ABOUT NBAC, NUVVE AND THE PROPOSED BUSINESS COMBINATION.
