In some cases, we may not expressly refer to the sources from which this information is derived. Management estimates are derived from industry and general publications and research, surveys and studies conducted by third parties and Next Nav's knowledge of its industry and assumptions based on such information and knowledge, which we believe to be reasonable. In addition, assumptions and estimates of Next Nav's and its industry's future performance are necessarily subject to a high degree of uncertainty and risk due to a variety of factors. These and other factors could cause NextNav's future performance and actual market growth, opportunity and size and the like to differ materially from our assumptions and estimates.

Use of Projections This Presentation contains estimated or projected information including financial information with respect to NextNav, including NextNav's projected revenue, gross margin, EBITDA, and unlevered free cash flow for 2021-2026. Such estimated or projected financial information constitutes forward-looking information, and is for illustrative purposes only and should not be relied upon as necessarily being indicative of future results. The assumptions and estimates underlying such estimated or projected financial information are inherently uncertain and are subject to a wide variety of significant business, economic, competitive and other risks and uncertainties that could cause actual results to differ materially from those contained in the prospective financial information. See "Forward-Looking Statements" below. Actual results may differ materially from the results contemplated by the estimated or projected financial information contained in this Presentation, and the inclusion of such information in this Presentation should not be regarded as a representation by any person that the results reflected in such estimates and projections will be achieved. Neither the independent registered public accounting firm of Spartacus nor the independent registered public accounting firm of NextNav, audited, reviewed, compiled, or performed any procedures with respect to the estimates or projections for the purpose of their inclusion in this Presentation, and accordingly, neither of them expressed an opinion or provided any other form of assurance with respect thereto for the purpose of this Presentation. Use of Non-GAAP Financial Measures This Presentation includes certain non-GAAP financial measures, including EBITDA and unlevered free cash flow, that are not prepared in accordance with accounting principles generally accepted in the United States ("GAAP") and that may be different from non-GAAP financial measures used by other companies. NextNav and Spartacus believe that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends of NextNav. These non-GAAP measures should not be considered in isolation from, or as an alternative to, financial measures determined in accordance with GAAP. Forward-looking non-GAAP financial measures are provided; they are presented on a non-GAAP basis without reconciliations of such forward-looking non-GAAP measures due to the inherent difficulty in forecasting and quantifying certain amounts that are necessary for such reconciliation.

A number of factors, many of which are outside of the control of NextNav and Spartacus, could cause actual results or outcomes to differ materially from those indicated by such forward-looking statements. These forward-looking statements are subject to a number of risks and uncertainties, including (i) changes in domestic and foreign business, market, financial, political and legal conditions; (ii) the inability of the NextNav and Spartacus to successfully or timely consummate 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 stockholders of Spartacus or equity holders of NextNav is not obtained; (iii) failure to realize the anticipated benefits of the proposed business combination; (iv) risks relating to the uncertainty of the N NEXTNAV projected financial information with respect to Next Nav, (v) risks related to the rollout of NextNav's technologies; (vi) the effects of competition on NextNav's business; (vii) the level of product service or product failures that could lead customers to use competitors' services; (viii) developments and changes in laws and regulations; (ix) the impact of significant investigative, regulatory or legal proceedings; (x) the amount of redemption requests made by Spartacus' public stockholders; (xi) the ability of Spartacus or the combined company to issue equity or equity-linked securities in connection with the proposed business combination or in the future; and (xii) those factors discussed in Spartacus' Annual Report on Form 10-K for the fiscal year ended December 31, 2020, under the heading "Risk Factors," and other documents of Spartacus filed, or to be filed, with the Securities and Exchange Commission ("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.
