Q2 2022 SHAREHOLDER LETTER INVESTORS.SHIFT4.COM Exhibit 99.1

Non-GAAP Financial Measures and Key Performance Indicators Safe Harbor Statement and Forward-Looking Information 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”); and Adjusted EBITDA. 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 months ended September 30, 2021 and December 31, 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 in "Network fees" and "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, 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 TSYS outage payments and associated costs, acquisition, restructuring and This presentation contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. 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 Finaro and The Giving Block and our ability to consummate the Finaro acquisition 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 integration costs, 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 changes in working capital exclusively related to the calendar effect on settlement funding balances, supply chain purchases accelerated to avoid procurement issues, payments and costs associated with the TSYS outage, acquisition, restructuring and integration costs, the impact of timing of annual performance bonuses, and payroll taxes on IPO-related equity- based compensation 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. 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 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 each 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 are unable to provide a reconciliation of Adjusted EBITDA for 2023 to net income (loss), the nearest comparable GAAP measure, and projected Adjusted Free Cash Flow to net cash provided by operating activities, the nearest comparable GAAP measure, without unreasonable efforts. 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 card payments that we authorize and settle on behalf of our merchants plus total cryptocurrency amounts transacted, translated at the spot price to U.S. dollars. This volume does not include volume processed through our gateway-only merchants. 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. 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; and the significant influence Rook has over us, including control over decisions that require the approval of stockholders. 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 for the year ended December 31, 2021, and in Part II, Item 1A in our Quarterly Report on Form 10-Q for the three months ended June 30, 2022 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. 2

Dear Shareholders, 3 We completed a reasonably strong quarter, growing our end-to-end volume, gross profit, and gross revenue less network fees 43%, 35%, and 34%, respectively. This strong growth continued through July despite a macro-economic picture that is becoming increasingly less clear. While we have not seen any data to suggest softening in consumer spending, it seems logical that inflation will put downward pressure on consumer demand. Despite these uncertainties, I am incredibly excited about the opportunities they present. Since founding the company in 1999, we have encountered numerous shocks to the economy. Whether it be the dot-com bubble, the tragedies of September 11, the housing crisis, or most recently, the COVID-19 pandemic, we have endured the challenges presented and grown revenue every year of our operations. More important than growth in the face of uncertainty are the lessons we’ve learned along the way. These lessons have instilled a culture of financial discipline, diversification and a vigilant eye for strategic needle movers. During the second quarter, our end-to-end volume was $16.9 billion, up 43% year over year, and is 307% of 2019 levels. I consider this volume growth especially impressive given what are, in retrospect, tough comps from 2021. The ongoing resumption of travel was quite welcomed, but it is tough to gauge consumer sentiment as we cycle over a year of stimulus and pent-up demand. Additionally, the second quarter had very little volume contribution from our new verticals. That stated, we completed several key integrations and have already begun growing volume from these new verticals including beginning processing for Starlink in the last week of the second quarter. As you can see from the chart on page 8, new vertical volume is growing quickly in the third quarter. We expect the pace to only accelerate as previously announced wins, such as Allegiant airlines, and several sports stadiums, begin to come online in the months ahead. Throughout the quarter we have been quite busy: • High growth core: We continue to win share in the restaurant and hospitality verticals, with volumes up 52% and 170%, respectively, on a 4-yr CAGR. Brand new properties, like Nobu Atlanta among others have selected Shift4 given the value our unique End-to-End offering provides. Additionally, SkyTab POS growth has been impressive, especially given it's still in beta, but given the cloud architecture and how we have engineered the product, we have already begun selectively insourcing distribution as an enhancement to our go-to-market strategy. Additionally, one of the world's largest restaurant groups has selected Shift4 with a significant SaaS commitment to power their tablet and mobile strategy across all of their restaurant brands. • Gateway conversions: As discussed previously, our gateway strategy aims to properly monetize the value of our technology and accelerate conversion of volume to our End-to- End platform, in addition to unlocking operational efficiencies. We are only a few months in to this program and have already contracted an estimated $700 million in annualized volume directly attributed to this initiative.

4 Jared Isaacman CEO jared@shift4.com • New verticals: We continue to be the category leader in software and payments serving the Sports & Entertainment and Theme Park vertical, posting signature wins routinely. We are proud to welcome Notre Dame, Wisconsin and Alabama Universities as customers, among others. We have found similar success in non-profits, gaming, and in exciting technologies companies, or what we refer to as "sexy tech," all of which are ramping volumes. • New signature wins: We signed Fanatics and TIME, both benefiting from investments we made in our payment platform including recurring billing, business intelligence and fraud management capabilities. • M&A: Lots of progress throughout the technical and operational integrations, commercial collaboration and regulatory approvals with respect to our previously announced Finaro acquisition. We anticipate closing in the 4th quarter this year. Additionally, the current economic climate has resulted in the development of an extensive pipeline of targets that are very compatible with our strategic objectives. Based on the performance of the business and the momentum in our new verticals and initiatives, we are sufficiently confident to raise Gross Revenue Less Network Fees and Adjusted EBITDA guidance as well provide a new guide to Adjusted Free Cash Flow. This business momentum is a stark contrast to our share price, which we believe has suffered disproportionately as public equity markets seek to assign value to an uncertain economy, particularly as a profitable company, with expanding adjusted free cash flow and an enviable balance sheet in the middle of our 23rd consecutive year of revenue growth. I have been Shift4’s largest shareholder since going public and have continued to grow my position in the face of this dislocation because, as I said previously, the opportunities presented by uncertainty are significant. I would like to end by expressing my immense appreciation for the Shift4 team. I am really proud of the performance as we deliver on so many initiatives, manage complexity, execute on the game plan and embrace the Shift4 way. Our corporate and social responsibility programs have made an impact across our workforce, our customers and in the local communities. This includes millions in funds raised to support charitable causes and significant commitment of time through volunteering. As always, I welcome any and all feedback from our investors. Please don’t hesitate to contact me directly.
