Forward-Looking Statements

Certain statements included in this press release are not historical facts but are forward-looking statements, including 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,” “project,” “forecast,” “predict,” “potential,” “seem,” “seek,” “future,” “outlook,” “target,” and similar expressions that predict or indicate future events or trends or that are not statements of historical matters, but the absence of these words does not mean that a statement is not forward-looking. These forward-looking statements include, but are not limited to, (1) references with respect to the anticipated benefits of the Business Combination and anticipated closing timing, (2) the sources and uses of funds for the Business Combination, (3) the anticipated capitalization and enterprise value of the combined company following the consummation of the Business Combination, and (4) current and future potential commercial and customer relationships. These statements are based on various assumptions, whether or not identified in this press release, and on the current expectations of VII’s and Banzai’s management and are not predictions of actual performance. 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 assumptions. Many actual events and circumstances are beyond the control of VII and Banzai. These forward-looking statements are subject to a number of risks and uncertainties, including: the inability of the parties to timely or successfully complete the Business Combination, including due to redemptions by VII’s public stockholders, the failure to satisfy the minimum net cash closing condition, the failure to maintain the Nasdaq listing of VII’s securities, the failure to obtain certain regulatory approvals or the satisfaction of other conditions to closing in the merger agreement; changes in domestic and foreign business, market, financial, political and legal conditions; the inability of the parties to successfully or timely consummate the Business Combination, including the risk that any required stockholder or regulatory approvals are not obtained, are delayed or are subject to unanticipated conditions that could adversely affect the combined company; failure to realize the anticipated benefits of the Business Combination; risks relating to the uncertainty of the projected financial information with respect to Banzai; Banzai’s ability to successfully and timely develop, sell and expand its technology and products, and otherwise implement its growth strategy; risks relating to Banzai’s operations and business, including information technology and cybersecurity risks, loss of customers and deterioration in relationships between Banzai and its employees; risks related to increased competition; risks relating to potential disruption of current plans, operations and infrastructure of Banzai as a result of the announcement and consummation of the Business Combination; risks that the post-combination company experiences difficulties managing its growth and expanding operations; the amount of redemption requests made by VII’s stockholders; the impact of geopolitical,

macroeconomic and market conditions, including the COVID-19 pandemic; the ability to successfully select, execute or integrate future acquisitions into the business, which could result in material adverse effects to operations and financial conditions; and those factors discussed in the sections entitled “Risk Factors” and “Special Note Regarding Forward-Looking Statements” in VII’s Quarterly Report on Form 10-Q for the quarter ended June 30, 2023, VII’s Annual Report on Form 10-K for the year ended December 31, 2022, the preliminary proxy statement / prospectus and in those documents that VII has filed, or will file, with the SEC. If any of these risks materialize or our assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements. The risks and uncertainties above are not exhaustive, and there may be additional risks that neither VII nor Banzai presently know or that VII and Banzai currently believe are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. In addition, forward-looking statements reflect VII’s and Banzai’s expectations, plans or forecasts of future events and views as of the date of this press release. VII and Banzai anticipate that subsequent events and developments will cause VII’s and Banzai’s assessments to change. However, while VII and Banzai may elect to update these forward-looking statements at some point in the future, VII and Banzai specifically disclaim any obligation to do so. These forward-looking statements should not be relied upon as representing VII’s and Banzai’s assessments as of any date subsequent to the date of this press release. Accordingly, undue reliance should not be placed upon the forward-looking statements.
