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 Inc.'s (“Volta” or the “Company”) 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. 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; 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; and subsequently filed Quarterly Reports on Form 10-Q under the heading "Risk Factors" and other documents of Volta filed, or to be filed, with the SEC. If any of these risks materialize 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 Volta presently does not know or that 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 Volta's expectations, plans or forecasts of future events and views as of the date of this Presentation. Volta anticipates that subsequent events and developments will cause Volta's assessments to change. However, while Volta may elect to update these forward-looking statements at some point in the future, Volta specifically disclaim any obligation to do so. These forward-looking statements should not be relied upon as representing 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. INDUSTRY AND MARKET DATA Although all information and opinions expressed in this Presentation, including market data and other statistical information, were obtained from sources believed to be reliable and are included in good faith, Volta has not independently verified the information and make no representation or warranty, express or implied, as to its accuracy or completeness. Some data is also based on the good faith estimates of Volta which are derived from its respective reviews of internal sources as well as independent sources. This Presentation contains preliminary information only, is subject to change at any time and, is not, and should not be assumed to be, complete or to constitute all the information necessary to adequately make an informed decision regarding your engagement with Volta. 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 promulgated under the Securities Act of 1933, as amended. Accordingly, such information and data may not be included in, may be adjusted in or may be presented differently in, any material to be filed with the SEC. Some of the financial information and data contained in this Presentation, such as EBITDA, EBITDA Margin, Adjusted EBITDA, and Adjusted EBITDA Margin, have not been prepared in accordance with United States generally accepted accounting principles ("GAAP”). Adjusted EBITDA reflects potential tax equity derived from government incentive programs. Additionally, for 2021, Adjusted EBITDA reflects impacts from non-recurring transaction costs, and adjustments from stock based compensation. Volta believes that these non-GAAP financial measures provide useful information to management and investors regarding certain financial and business trends relating to Volta's financial condition and results of operations. Volta believes that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating projected operating results and trends in and in comparing Volta'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 income that are required by GAAP to be recorded in Volta's financial statements. In addition, they are subject to inherent limitations as they reflect the exercise of judgments by management about which expenses and income are excluded or included in determining these non-GAAP financial measures.
