These forward-looking statements include, but are not limited to, statements regarding estimates and forecasts of other financial and performance metrics and projections of market opportunity and market share. These statements are based on various assumptions, whether or not identified in this Presentation, and on the current expectations of Volta Industries, Inc.'s ("Volta" or the "Company") and Tortoise Acquisition Corp. Il's ("Tortoise II) 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 may differ from assumptions and such differences may be material. Many actual events and circumstances are beyond the control of Volta and Tortoise II. 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; the inability of the parties to successfully or timely consummate the potential business combination between Volta and Tortoise II and related transactions (the "Proposed Business Combination"), including the risk that any required regulatory approvals are not obtained, are delayed or are subject to unanticipated conditions that could adversely affect the combined company or the expected benefits of the Proposed Business Combination or that the approval of the shareholders of Tortoise II or Volta is not obtained; failure to realize the anticipated benefits of the Proposed Business Combination; risks relating to the uncertainty of the projected financial information with respect to Volta; risks related to the rollout of Volta's business and the timing of expected business milestones; the effects of competition on Volta's business; the amount of redemption requests made by Tortoise Il's public shareholders; the ability of Tortoise Il or the combined company to issue equity or equity-linked securities in connection with the Proposed Business Combination or in the future; and those factors discussed in Tortoise Il's final prospectus filed with the Securities and Exchange Commission ("SEC") on September 14, 2020 and subsequently filed Quarterly Report on Form 10-Q under the heading "Risk Factors" and other documents of Tortoise II filed, or to be filed, with the SEC. If any of these risks materialize or Tortoise Il's or Volta's assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements. There may be additional risks that neither Tortoise Il nor Volta presently know or that Tortoise II and Volta 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 Tortoise Il's and Volta's expectations, plans or forecasts of future events and views as of the date of this Presentation. Tortoise II and Volta anticipate that subsequent events and developments will cause Tortoise Il's and Volta's assessments to change. However, while Tortoise II and Volta may elect to update these forward-looking statements at some point in the future, Tortoise II and Volta specifically disclaim any obligation to do so. These forward-looking statements should not be relied upon as representing Tortoise Il's and Volta'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.
