Forward-looking statements may be identified by the use of words such as &#34;intend,&#34; &#34;expect&#34;, and &#34;may&#34;, and other similar expressions that predict or indicate future events or that are not statements of historical matters, including our 2024 Revenue and Consolidated Adjusted EBITDA outlook. Forward-looking statements are based on current information available at the time the statements are made and on management&#x2019;s reasonable belief or expectations with respect to future events, and are subject to risks and uncertainties, many of which are beyond the Company&#x2019;s control, that could cause actual performance or results to differ materially from the belief or expectations expressed in or suggested by the forward-looking statements. Additional factors or events that could cause actual results to differ may also emerge from time to time, and it is not possible for the Company to predict all of them. Forward-looking statements speak only as of the date on which they are made, and the Company undertakes no obligation to update any forward-looking statement to reflect future events, developments or otherwise, except as may be required by applicable law. Investors are referred to the Company&#x2019;s filings with the Securities and Exchange Commission, including its Annual Report on Form 10-K for the year ended December 31, 2023, for additional information regarding the risks and uncertainties that may cause actual results to differ materially from those expressed in any forward-looking statement.</font></p>

  <p style="font-size:10pt;margin-top:0;font-family:Times New Roman;margin-bottom:8pt;text-align:justify;"><font style="color:#000000;white-space:pre-wrap;font-size:11pt;font-family:'Calibri',sans-serif;min-width:fit-content;">In this release we present certain supplemental financial information regarding Consolidated Adjusted EBITDA that is not required by, or presented in accordance with, GAAP. We calculate Consolidated Adjusted EBITDA as net income (loss) before interest expense, income tax expense (benefit) and depreciation and amortization, adjusted for the impact of certain other items, including stock-based compensation expense and acquisition-related costs.</font></p>
  <p style="font-size:10pt;margin-top:0;font-family:Times New Roman;margin-bottom:8pt;text-align:justify;"><font style="color:#000000;white-space:pre-wrap;font-size:11pt;font-family:'Calibri',sans-serif;min-width:fit-content;">Consolidated Adjusted EBITDA is one of the primary metrics used by management to evaluate our financial performance and compare it to that of our peers, evaluate the effectiveness of our business strategies, make budgeting and capital allocation decisions and in connection with our executive incentive compensation. Consolidated Adjusted EBITDA is also frequently used by analysts, investors and other interested parties to evaluate companies in our industry. Further, we believe it is helpful in highlighting trends in our operating results because it allows for more consistent comparisons of financial performance between periods by excluding gains and losses that are non-operational in nature or outside the control of management, and by excluding items that may differ significantly depending on long-term strategic decisions regarding capital structure, the tax jurisdictions in which we operate and capital investments.</font></p>
  <p style="font-size:10pt;margin-top:0;font-family:Times New Roman;margin-bottom:8pt;text-align:justify;"><font style="color:#000000;white-space:pre-wrap;font-size:11pt;font-family:'Calibri',sans-serif;min-width:fit-content;">Consolidated Adjusted EBITDA does, however, have certain limitations and should not be considered as an alternative to net income (loss) or any other performance measure derived in accordance with GAAP. Our presentation of Consolidated Adjusted EBITDA should not be construed as an inference that our future results will be unaffected by unusual or non-recurring items for which we may make adjustments. In addition, Consolidated Adjusted EBITDA may not be comparable to similarly titled measures used by other companies in our industry or across different industries, and other companies may not present it or</font><font style="color:#000000;white-space:pre-wrap;font-size:11pt;font-family:'Calibri',sans-serif;min-width:fit-content;"> </font></p>

Management compensates for these limitations by using Consolidated Adjusted EBITDA as a supplemental financial metric and in conjunction with our results prepared in accordance with GAAP. We encourage investors and others to review our financial information in its entirety, not to rely on any single measure and to view Consolidated Adjusted EBITDA in conjunction with the related GAAP measures.</font></p>
  <p style="font-size:10pt;margin-top:0;font-family:Times New Roman;margin-bottom:8pt;text-align:justify;"><font style="color:#000000;white-space:pre-wrap;font-size:11pt;font-family:'Calibri',sans-serif;min-width:fit-content;">We have provided estimates regarding Consolidated Adjusted EBITDA for 2024. These projections account for estimates of revenue, operating margins and corporate and other costs. However, we cannot reconcile our projection of Consolidated Adjusted EBITDA to net income (loss), the most directly comparable GAAP measure, without unreasonable efforts because of the unpredictable or unknown nature of certain significant items excluded from Consolidated Adjusted EBITDA and the resulting difficulty in quantifying the amounts thereof that are necessary to estimate net income (loss). Specifically, we are unable to estimate for the future impact of certain items, including income tax (expense) benefit, stock-based compensation expense, fair value changes and the accounting for the issuance of the Series A-2 preferred stock. We expect the variability of these items could have a significant impact on our reported GAAP financial results.</font></p>
