prioritycommerce.com 1 Disclaimer Important Notice Regarding Forward-Looking Statements and Non-GAAP Measures This presentation of Priority Technology Holdings, Inc. (“Priority”, “PRTH”, “we”, “our”, or “us”) 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 or phrases of similar meaning. These forward-looking statements include, but are not limited to, Priority’s 2024 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 12, 2024. 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 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 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. Please refer to the appendix slides at the end of this presentation for a reconciliation of such non-GAAP financial measures to the most comparable GAAP numbers. Adjusted Gross profit and Adjusted Gross profit margin referred throughout this presentation are non-GAAP measures. Adjusted Gross profit is calculated by subtracting Cost of services (excluding depreciation and amortization) from Revenue. Adjusted Gross profit margin is calculated by dividing Adjusted Gross Profit discussed above by Revenue. Adjusted EBITDA and Adjusted EBITDA margin referred to throughout this presentation are non-GAAP measures. Adjusted EBITDA is calculated as net income prior to interest expense, tax expense, depreciation and amortization expense, adjusted to add back certain non-cash charges and / or non-recurring charges deemed to not be part of normal operating expenses. Adjusted EBITDA margin is calculated by dividing Adjusted EBITDA discussed above by Revenue. Free cash flow (“FCF”) and free cash flow conversion referred to throughout this presentation are non-GAAP measures. Free cash flow is calculated as Adjusted EBITDA less Additions to property, equipment and software (“CapEx”) as reported in our statement of cash flows. Free cash flow conversion is calculated as FCF / Adjusted EBITDA. Recurring, re-occurring and other revenues referred to throughout this presentation are non-GAAP measures. Recurring revenue represents revenue which are not dependent upon transaction volume or transaction count. Re-occurring revenue represents revenue which are dependent upon transaction volume or transaction count. Other revenues are comprised of any remaining revenue streams that do not qualify as recurring or re-occurring based on the definitions above. Percentage of Recurring and re-occurring revenues is calculated by dividing total of recurring and re-occurring revenues by total revenues. Adjusted gross profit from recurring revenue is calculated by subtracting Cost of services related to recurring revenue (excluding depreciation and amortization) from Recurring revenue. Additionally, we present guidance for Adjusted EBITDA and Adjusted EBITDA as percentage of revenue, non-GAAP measures without reconciliation due to the inherent difficulty in forecasting and quantifying certain amounts that are necessary for such reconciliations. Special Notice THIS MANAGEMENT PRESENTATION MAY CONTAIN MATERIAL NON-PUBLIC INFORMATION CONCERNING THE COMPANY OR ITS SECURITIES. BY ACCEPTING THIS MANAGEMENT PRESENTATION, THE RECIPIENT AGREES TO USE ANY SUCH INFORMATION IN ACCORDANCE WITH ITS COMPLIANCE POLICIES, CONTRACTUAL OBLIGATIONS AND APPLICABLE LAW, INCLUDING FEDERAL AND STATE SECURITIES LAWS.
