2 DISCLAIMER Important Notice Regarding Forward-Looking Statements and Non-GAAP Measures This presentation contains “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Such statements include, but are not limited to, statements about future financial and operating results, our plans, objectives, expectations and intentions with respect to future operations, products and services, and other statements identified by words such as “may,” “will,” “should,” “anticipates,” “believes,” “expects,” “plans,” “future,” “intends,” “could,” “estimate,” “predict,” “projects,” “targeting,” “potential” or “contingent,” “guidance,” “anticipates,” “outlook” or words of similar meaning. These forward-looking statements include, but are not limited to, Priority Technology Holdings, Inc.’s (“Priority”, “we”, “our” or “us”) 2023 outlook and statements regarding our market and growth opportunities. Such forward-looking statements are based upon the current beliefs and expectations of our management and are inherently subject to significant business, economic and competitive risks, trends and uncertainties that could cause actual results to differ materially from those projected, expressed, or implied by such forward-looking statements. Our actual results could differ materially, and potentially adversely, from those discussed or implied herein. We caution that it is very difficult to predict the impact of known factors, and it is impossible for us to anticipate all factors that could affect our actual results. All forward-looking statements are expressly qualified in their entirety by these cautionary statements. You should evaluate all forward-looking statements made in this presentation in the context of the risks and uncertainties disclosed in our Securities and Exchange Commission (“SEC”) filings, including our Annual Report on Form 10-K filed with the SEC on March 23, 2023 and our Quarterly Report on Form 10-Q filed with the SEC on August 10, 2023. These filings are available online at www.sec.gov or www.prioritycommerce.com. We caution you that the important factors referenced above may not contain all of the factors that are important to you. In addition, we cannot assure you that we will realize the results or developments we expect or anticipate or, even if substantially realized, that they will result in the consequences we anticipate or affect us or our operations in the way we expect. You are cautioned not to place undue reliance on forward-looking statements as a predictor of future performance. The forward-looking statements included in this presentation are made only as of the date hereof. We undertake no obligation to publicly update or revise any forward-looking statement as a result of new information, future events or otherwise, except as otherwise required by law. If we do update one or more forward-looking statements, no inference should be made that we will make additional updates with respect to those or other forward-looking statements. We qualify all of our forward-looking statements by these cautionary statements. This presentation includes certain non-GAAP financial measures 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. Priority believes 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 the Company. These non-GAAP measures should not be considered in isolation from, or as an alternative to, financial measures determined in accordance with GAAP. See the footnotes on the slides where these measures are discussed and the slides at the end of this presentation for a reconciliation of such non-GAAP financial measures to the most comparable GAAP numbers. Additionally, we present guidance for Adjusted EBITDA and Adjusted EBITDA as percentage of Adjusted Gross Profit, non-GAAP measures without reconciliation due to the inherent difficulty in forecasting and quantifying certain amounts that are necessary for such reconciliations. See more information in Priority’s earnings press release. Adjusted Gross profit referred throughout this presentation is a non-GAAP measure calculated by subtracting Cost of services (excluding depreciation and amortization) from Revenue. Adjusted Gross profit margin referred throughout this presentation is a non-GAAP measure calculated by dividing Adjusted Gross Profit discussed above by Revenue. See Appendix 1 of this presentation for a reconciliation of Adjusted Gross Profit to Gross Profit as per GAAP and Priority’s earnings press release for more details.
