FOUR Reports Second Quarter 2020 Results August 6, 2020 ALLENTOWN, Pa – (BUSINESS WIRE) Shift4 Payments, Inc. (NYSE: FOUR “the Company”), a leading provider of integrated payment processing solutions, today announced its second quarter 2020 results. ‘We are incredibly proud to report our results for the second quarter 2020, during which we became a publicly traded company’ said Jared Isaacman, founder and chief executive officer. ‘The rebound in end-to-end payment volumes experienced through the quarter highlights the resiliency of our merchant base and the ability of our software partners to act on Shift4’s compelling value proposition and continue to win share.’ Gross revenue for the second quarter of 2020 decreased 21% to $141.8 million from $180.5 million in the prior year period, primarily driven by the impact of the COVID-19 pandemic on our end-to-end payment volumes and gateway transactions. Net loss was $75.0 million or a loss of $0.03 per share (basic and diluted) for our Class A and Class C common stock. End-to-end payment volume was $4.2 billion for the second quarter of 2020, which resulted in gross revenue less network fees of $67.4 million. This compares with $5.5 billion and $75.3 million for the prior year period; a decrease of 23% and 10% respectively. Adjusted net loss was $14.4 million for the second quarter of 2020 compared to a loss of $4.4 million for the prior year period. Adjusted EBITDA was $14.8 million, down 38% from $24.0 during the prior year period. A detailed investor presentation can be found at investors.shift4.com Exhibit 99.1

Non-GAAP Financial Measures and Key Performance Indicators   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, or GAAP. These non-GAAP financial measures include: gross revenue less network fees, which includes interchange and assessment fees; adjusted net loss; earnings before interest expense, income taxes, depreciation, and amortization, or 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. Adjusted net loss represents net loss adjusted for certain non-cash and other non-recurring items that management believes are not indicative of ongoing operations, such as, acquisition, restructuring and integration costs, equity-based compensation expense, management fees and other non-recurring 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 non-recurring items that management believes are not indicative of ongoing operations. These adjustments include acquisition, restructuring and integration costs, equity-based compensation expense, management fees and other nonrecurring items. 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, and adjusted net loss 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, we present end-to-end payment volume, a key performance indicator, which is defined as the total dollar amount of card payments that we authorize and settle on behalf of our merchants. This volume does not include volume processed through our gateway-only merchants.
