Safe Harbor Statement and Forward Looking Information Non-GAAP Financial Measures and Key Performance Indicators This presentation contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. We intend- such forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in Section 27A of the Securities Act of 1933, as amended and Section 21E of the Securities Exchange Act of 1934, as amended. All statements contained in this presentation that do not relate to matters of historical fact should be considered forward-looking statements, including statements regarding Shift4 Payments, Inc.’s (“our”, the “Company” or "Shift4”) expectations regarding new customers; acquisitions and other transactions, including of our sales partners and their residual streams, and our ability to close said transactions on the timeline we expect or at all; our plans and agreements regarding future payment processing commitments; our expectations with respect to economic recovery; our stock price; and anticipated financial performance, including our financial outlook for fiscal year 2022 and future periods. These statements are neither promises nor guarantees, but involve known and unknown risks, uncertainties and other important factors that may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements, including, but not limited to, the following: the effect of the COVID-19 global pandemic and any variants of the virus on our business and results of operations; our ability to differentiate ourselves from our competitors and compete effectively; our ability to anticipate and respond to changing industry trends and merchant and consumer needs; our ability to continue making acquisitions of businesses or assets; our ability to continue to expand our market share or expand into new markets; our reliance on third-party vendors to provide products and services; our ability to integrate our services and products with operating systems, devices, software and web browsers; our ability to maintain merchant and software partner relationships and strategic partnerships; the effects of global economic, political and other conditions, including inflationary pressure and rising interest rates, on consumer, business and government spending; our compliance with governmental regulation and other legal obligations, particularly related to privacy, data protection and information security, and consumer protection laws; our ability to establish, maintain and enforce effective risk management policies and procedures; our ability to protect our systems and data from continually evolving cybersecurity risks, security breaches and other technological risks; potential harm caused by software defects, computer viruses and development delays; the effect of degradation of the quality of the products and services we offer; potential harm caused by increased customer attrition; potential harm caused by fraud by merchants or others; potential harm caused by damage to our reputation or brands; our ability to recruit, retain and develop qualified personnel; our reliance on a single or limited number of suppliers; the effects of seasonality and volatility on our operating results; the effect of various legal proceedings; our ability to raise additional capital to fund our operations; our ability to protect, enforce and defend our intellectual property rights; our ability to establish and maintain effective internal control over financial reporting and disclosure controls and procedures; our compliance with laws, regulations and enforcement activities that affect our industry; our dependence on distributions from Shift4 Payments, LLC to pay our taxes and expenses, including payments under the Tax Receivable Agreement; the significant influence Rook has over us, including control over decisions that require the approval of stockholders; and the potential impact of material weaknesses in our internal control over financial reporting. These and other important factors are described in “Cautionary Note Regarding Forward-Looking Statements” and “Risk Factors” in Part I, Item 1A. in our Annual Report on Form 10-K/A for the year ended December 31, 2021 and could cause actual results to differ materially from those indicated by the forward-looking statements made in this presentation.. Any such forward-looking statements represent management’s estimates as of the date of this presentation. While we may elect to update such forward-looking statements at some point in the future, we disclaim any obligation to do so, even if subsequent events cause our views to change. We use supplemental measures of our performance which are derived from our consolidated financial information but which are not presented in our consolidated financial statements prepared in accordance with generally accepted accounting principles ("GAAP"). These non-GAAP financial measures include: gross revenue less network fees, which includes interchange and assessment fees; adjusted net income; adjusted net income per share; free cash flow; adjusted free cash flow; earnings before interest, income taxes, depreciation, and amortization (“EBITDA”); Adjusted EBITDA; Adjusted EBITDA conversion rate; and Adjusted EBITDA margin. Gross revenue less network fees represents a key performance metric that management uses to measure changes in the mix and value derived from our customer base as we continue to execute our strategy to expand our reach to serve larger, complex merchants. For the three and nine months ended September 30, 2021, gross revenue less network fees excludes the impact of the payments to merchants, included in "Gross revenue," and payments to partners and associated expenses due to the TSYS outage, included "Other costs of sales" in our Consolidated Statements of Operations for the same periods. These are nonrecurring payments that occurred outside of our day-to-day operations, and we have excluded them in order to provide more useful information to investors in the evaluation of our performance period-over period. Adjusted net income represents net income (loss) adjusted for certain non-cash and other nonrecurring items that management believes are not indicative of ongoing operations, such as the TSYS outage payments and associated costs, acquisition, restructuring and integration costs, revaluation of contingent liabilities, change in Tax Receivable Agreement (“TRA”) liability, equity-based compensation expense, and other nonrecurring items. Adjusted EBITDA is the primary financial performance measure used by management to evaluate its business and monitor results of operations. Adjusted EBITDA represents EBITDA further adjusted for certain non-cash and other nonrecurring items that management believes are not indicative of ongoing operations. These adjustments include the TSYS outage payments and associated costs, acquisition, restructuring and integration costs, revaluation of contingent liabilities, change in TRA liability, equity-based compensation expense and other nonrecurring items. Free cash flow represents net cash provided by operating activities adjusted for non-discretionary capital expenditures. Adjusted free cash flow represents free cash flow further adjusted for certain transactions that are not indicative of future operating cash flows, including settlement activity, which represents the change in our settlement obligation, which fluctuated based on volumes and calendar timing, payments and costs associated with the TSYS outage, acquisition, restructuring and integration costs, the impact of timing of annual performance bonuses, and other nonrecurring expenses that are not indicative of ongoing activities. We believe adjusted free cash flow is useful to measure the funds generated in a given period that are available to invest in the business, to repurchase stock and to make strategic decisions. We believe this supplemental information enhances shareholders’ ability to evaluate the Company’s performance. The Adjusted EBITDA conversion rate is calculated as Adjusted Free Cash Flow divided by Adjusted EBITDA. We use non-GAAP financial measures to supplement financial information presented on a GAAP basis. We believe that excluding certain items from our GAAP results allows management to better understand our consolidated financial performance from period to period and better project our future consolidated financial performance as forecasts are developed at a level of detail different from that used to prepare GAAP-based financial measures. Moreover, we believe these non-GAAP financial measures provide our stakeholders with useful information to help them evaluate our operating results by facilitating an enhanced understanding of our operating performance and enabling them to make more meaningful period to period comparisons. There are limitations to the use of the non-GAAP financial measures presented in this presentation. Our non-GAAP financial measures may not be comparable to similarly titled measures of other companies. Other companies, including companies in our industry, may calculate non-GAAP financial measures differently than we do, limiting the usefulness of those measures for comparative purposes. The non-GAAP financial measures are not meant to be considered as indicators of performance in isolation from or as a substitute for net income (loss) prepared in accordance with GAAP, and should be read only in conjunction with financial information presented on a GAAP basis. Reconciliations of EBITDA and Adjusted EBITDA, gross revenue less network fees, adjusted net income, adjusted net income per share, free cash flow and adjusted free cash flow to its most directly comparable GAAP financial measure are presented at the end of this presentation. We encourage you to review the reconciliations in conjunction with the presentation of the non-GAAP financial measures for each of the periods presented. In future fiscal periods, we may exclude such items and may incur income and expenses similar to these excluded items. In addition, key performance indicators include end-to-end payment volume, spread and margin. End- to-end payment volume is defined as the total dollar amount of payments that we deliver for settlement on behalf of our merchants. Included in end-to-end volume are dollars routed via our international payments platform and alternative payment methods, including cryptocurrency donations, plus volume we route to one or more third party merchant acquirers on behalf of strategic enterprise merchant relationships, translated at the spot price to U.S. dollars. This volume does not include volume processed through our legacy gateway-only offering. Spread represents the average yield Shift4 earns on the average end-to-end payment volume processed for a given period after network fees. Spread is calculated as payments-based revenue less gateway revenue and network fees for a given period divided by the end-to-end payment volume processed for the similar period. Adjusted EBITDA Margin represents Adjusted EBITDA divided by gross revenue less network fees. 2

Dear Shareholders, Throughout our 25 years in business, we have navigated through “dot-com”, the great recession, and a once-in-a-century pandemic. We understand how to innovate and grow during the best and most challenging of economic and geopolitical circumstances. I mentioned earlier this year that as uncertain as the road ahead may be, this is typically when Shift4 performs at our best. We know how to prioritize and focus our resources towards initiatives that ‘move the needle’ and I believe the results from this quarter reflect well on that statement. We completed another reasonably strong quarter, setting new quarterly records for volume, Gross Profit, Gross Revenue less Network Fees, Net Income, Adjusted EBITDA, and Adjusted Free Cash Flow. We grew our end-to-end volume, gross profit, and gross revenue less network fees 53%, 118%, and 33%, respectively. We generated $46.4 million of net income, up from a net loss of ($13.8) million a year ago, and grew our Adjusted EBITDA 53% for the quarter while expanding our Adjusted EBITDA margins considerably. I am especially proud of this performance as it underscores our ability to make investments in our growth initiatives, such as international expansion and launching new products like SkyTab – while also executing in our core business in the face of what could be a deteriorating economy. With a large base of existing customers and a distinct right-to-win in several verticals, we have positioned the company to differentiate, take share and grow even if there is an eventual slowdown in consumer spending. During the third quarter, our end-to-end volume was $20.6 billion, up 53% year over year, and up 349% from 2019 levels. In addition to consistent net new wins, this quarter benefited from a greater contribution of volume from our new verticals, including Sports & Entertainment, Gaming and Sexy Tech. Additionally, we were able to renew several enterprise gateway customers under more favorable economic terms consistent with our previously announced ‘gateway sunset strategy’. We also signed, closed and integrated our first international acquisition which we believe substantially enhances our ability to attract and integrate new customers in line with our global expansion strategy. While the economic contribution was de minimis to the quarter, the feature enhancements are quite impressive and I encourage you all to visit dev.shift4.com to try them out. Our previously signed acquisition of Finaro is on track to close by Q1 2023 pending regulatory approval. Throughout the quarter we have been quite busy: • High growth core: In addition to signing many notable hotels and restaurants, we fully released our next generation restaurant product SkyTab POS. As a component of this initiative, we insourced several of our best distribution partners located in key markets. As a result, we are now able to go to market with equal strength in both ‘direct sales’ and through third-party dealers. The result is greater control over the customer experience and significantly reduced expenses driving superior unit economics. Overall, we anticipate a steady increase in new customer production. 3

• Gateway conversions: The previously announced gateway sunset program continues to deliver favorable results. While we remain early in this multi-year initiative, we have already pulled forward volume that we otherwise may not have achieved, as well as renewed agreements with several enterprise customers on economic terms equivalent to our E2E offering. This initiative is still in the early innings with a considerable pool of gateway volume that will drive growth for years into the future. • New verticals: As mentioned above, all of our new verticals have continued to ramp throughout the quarter. This includes record volume contribution from our Sports & Entertainment and Gaming solutions as well as our strategic customer relationships. • M&A: The quarter was spent preparing for the closing of the previously announced Finaro acquisition, as well as signing and closing on the acquisition of a European PSP that brings advanced anti-fraud, BI and recurring billing functionality. Our pipeline of opportunities remains robust as we continue to execute on our global expansion priorities alongside other accelerants to our growth and product strategy. • Talent: We’ve leveraged our advantages above to add great talent at a time when many in our industry are downsizing. Notably, we welcomed Nancy Disman as CFO and created a new Transformation division. I fully expect us to continue to responsibly add talent to meet the demand for our services. I attribute our performance this quarter to well-executed organic initiatives, like SkyTab POS and our gateway sunset program, as well as disciplined investments in new verticals that moderate the typical seasonality that would have been expected in our high growth core. We continue to deliver on the expectations established during our 2021 Investor Day and as a result we are raising 2022 volume, Gross Revenue less Network Fees, Adjusted EBITDA, Adjusted FCF outlook and reaffirming our mid-term outlook. We will expand upon this letter during our earnings call and our 2022 SkyTab Showcase and Business Update event. Like last quarter, I would like to thank the Shift4 team for working tirelessly to deliver such impressive results. We are growing very quickly, and change is never easy. The team has leaned in to the ‘Shift4 Way’ established last year and the results are quite apparent. We will never stop looking to improve as we embrace the challenge and endeavor to illuminate the world through connected commerce. On that note, I always welcome ideas, business opportunities, areas of improvement and general feedback from our investors. Please don’t hesitate to contact me directly.
