Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Basis of Presentation and Significant Accounting Policies	Organization, Basis of Presentation and Significant Accounting Policies Organization Shift4 Payments, Inc. (“Shift4 Payments” or “the Company”) was incorporated in Delaware in order to carry on the business of Shift4 Payments, LLC and its consolidated subsidiaries. The Company is a leading independent provider of software and payment processing solutions in the United States (“U.S.”) based on total volume of payments processed. Basis of Presentation The accompanying interim condensed consolidated financial statements of the Company are unaudited. These interim condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the U.S. (“U.S. GAAP”) and the applicable rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) for interim financial information. These fi nancial statements do not include all information and footnotes required by U.S. GAAP for complete financial statements. The December 31, 2023 Condensed Consolidated Balance Sheet was derived from audited financial statements as of that date, but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, the unaudited condensed consolidated financial statements reflect all adjustments consisting only of normal recurring adjustments necessary to state fairly the financial position, results of operations and cash flows for the periods presented in conformity with U.S. GAAP applicable to interim periods. The results of operations for the interim periods presented are not necessarily indicative of results for the full year or future periods. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the related notes thereto as of and for the fiscal year ended December 31, 2023, as disclosed in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023 (the “2023 Form 10-K”). The unaudited condensed consolidated financial statements include the accounts of Shift4 Payments, Inc. and its wholly-owned subsidiaries. Shift4 Payments, Inc. consolidates the financial results of Shift4 Payments, LLC, which is considered a variable interest entity. Shift4 Payments, Inc. is the primary beneficiary and sole managing member of Shift4 Payments, LLC and has decision making authority that significantly affects the economic performance of the entity. As a result, the Company consolidates Shift4 Payments, LLC and reports a noncontrolling interest representing the economic interest in Shift4 Payments, LLC held by Rook Holdings Inc. (“Rook”). All intercompany balances and transactions have been eliminated in consolidation. The assets and liabilities of Shift4 Payments, LLC represent substantially all of the consolidated assets and liabilities of Shift4 Payments, Inc. with the exception of certain cash balances, amounts payable under the Tax Receivable Agreement (“TRA”), and the aggregate principal amount of $690.0 million of 2025 Convertible Notes and $632.5 million of 2027 Convertible Notes (together, the “Convertible Notes”) that are held by Shift4 Payments, Inc. directly. As of September 30, 2024 and December 31, 2023 , $17.3 million and $3.6 million of cash, respectively, w as directly held by Shift4 Payments, Inc. A s of September 30, 2024 and December 31, 2023, the TRA liabil ity was $370.1 million and $5.1 million, respectively. See Note 13 for further information on the increase in TRA liability during the three months ended September 30, 2024. In connection with the issuance of the Convertible Notes, Shift4 Payments, Inc. entered into Intercompany Convertible Notes with Shift4 Payments, LLC, whereby Shift4 Payments, Inc. provided the net proceeds from the issuance of the Convertible Notes to Shift4 Payments, LLC in the amount of $1,322.5 million. Shift4 Pa yments, Inc., which was incorporated on November 5, 2019, has not had any material operations on a standalone basis since its inception, and all of the operations of the Company are carried out by Shift4 Payments, LLC and its subsidiaries. Change in Presentation of Consolidated Balance Sheets Prior year balances have been adjusted to present “Current TRA liability” on its own line item rather than within “Accrued expenses and other current liabilities” on the Company’s unaudited Condensed Consolidated Balance Sheets to conform to the current period presentation. Prior year balances have been adjusted to present “Noncurrent TRA liability” on its own line item rather than within “Other noncurrent liabilities” on the Company’s unaudited Condensed Consolidated Balance Sheets to conform to the current period presentation. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the Company’s unaudited condensed consolidated financial statements and accompanying notes. Significant estimates inherent in the preparation of the accompanying unaudited condensed consolidated financial statements include estimates of fair value of acquired assets and liabilities through business combinations, fair value of contingent liabilities related to earnout payments, deferred income tax valuation allowances, amounts associated with the Company’s tax receivable agreement with Rook and certain affiliates of Searchlight Capital Partners, L.P. (together, the “Continuing Equity Owners”), fair value of debt instruments, allowance for doubtful accounts, income taxes, investments in securities and noncontrolling interests. Estimates are based on past experience and other considerations reasonable under the circumstances. Actual results may differ from these estimates. Significant Accounting Policies The Company’s significant accounting policies are discussed in Note 1 to Shift4 Payments, Inc.’s consolidated financial statements as of and for the year ended December 31, 2023 in the 2023 Form 10-K. There have been no significant changes to these policies which have had a material impact on the Company’s unaudited condensed consolidated financial statements and related notes during the nine months ended September 30, 2024. Cash and Cash Equivalents and Restricted Cash Highly liquid investments with maturities of three months or less at the date of purchase are considered to be cash equivalents and are stated at cost, which approximates fair value. The Company’s cash equivalents consist of highly liquid investments in money market funds. On September 30, 2024 the Company entered into the Settlement Line Credit Agreement (the “Settlement Line Agreement”), by and between Shift4 LLC, as the borrower, and Citizens Bank, N.A. (“Citizens”), as the lender, providing for a settlement line of credit with an aggregate available amount of up to $100.0 million (the “Settlement Line”). The purpose of the Settlement Line is to provide financing for certain settlement obligations of Shift4 LLC’s merchants and to eliminate the requirement for cash collateral under the sponsorship agreement with Citizens (the “Sponsorship Agreement”), which was amended in conjunction with the closing of the Settlement Line Agreement. There were no borrowings under the Settlement Line as of September 30, 2024. The Settlement Line is scheduled to mature on September 29, 2025, subject to extensions. Draws under the Settlement Line bear interest at a rate per annum equal to either (x) a daily simple SOFR based rate (subject to a 0.0% floor), plus an applicable margin of 0.75%, or (y) to the extent required by the Settlement Line Agreement upon the occurrence of certain specified events, an alternate base rate (equal to the highest of the Federal Funds Effective Rate plus 0.50%, the daily simple SOFR rate (subject to a 0.0% floor) plus 1.00%, and the prime rate announced by Citizens from time to time). In addition to making periodic interest payments on the principal amount of outstanding draws under the Settlement Line, the Company is required to pay an unused fee under the Settlement Line in respect of the unused availability thereunder at a rate equal to 0.15% per annum. In the fourth quarter of 2023, the Company acquired Credorax, Inc. d/b/a Finaro (“Finaro”). Finaro’s principal activities consist of the provision of integrated acquiring and payment processing services to merchants located in Europe and the United Kingdom (the “U.K.”). Unlike the Company’s U.S. business, Finaro operates as a full acquirer, and without a sponsor bank like the Company has historically operated with in the U.S. As a result, the Company’s European and U.K. business includes settlement processing assets and liabilities. These assets primarily include settlement-related cash and funds receivable from card networks. Cash and cash equivalents held on behalf of merchants and other payees are included within “Settlement assets” on the unaudited Condensed Consolidated Balance Sheet. The changes in settlement cash and cash equivalents are included within “Settlement activity, net” within Operating activities on the Company’s unaudited Condensed Consolidated Statements of Cash Flows. The following table provides a reconciliation between cash and cash equivalents on the unaudited Condensed Consolidated Balance Sheets and the unaudited Condensed Consolidated Statements of Cash Flows: September 30, 2024 December 31, 2023 Cash and cash equivalents $ 1,426.4 $ 455.0 Restricted cash — 84.4 Cash and cash equivalents included in Settlement assets 169.0 182.4 Total cash and cash equivalents and restricted cash on the unaudited Condensed Consolidated Statements of Cash Flows $ 1,595.4 $ 721.8 The Company maintains its cash with what are widely considered to be high credit quality financial institutions. U.S. cash balances are insured by the Federal Deposit Insurance Corporation (“FDIC”) up to $250 thousand per bank. The Company maintains cash and cash equivalent balances in excess of FDIC limits. Settlement Assets and Liabilities Settlement assets and liabilities are balances related to the settlement process which involves the transferring of funds between card issuers, merchants and other third parties. The Company currently operates under two different models: (1) a sponsorship model and (2) a direct member model. In the U.S., the Company operates under the sponsorship model and outside the U.S. the Company primarily operates under the direct member model. The Company’s operations outside the U.S. are primarily related to the business of Finaro, which was acquired in the fourth quarter of 2023. Sponsorship Model In the U.S., the Company operates under the sponsorship model. In order for the Company to provide payment processing services, Visa, MasterCard and other payment networks require sponsorship by a member clearing bank. The Company has an agreement with banks and financial institutions (the “Sponsoring Member”), to provide sponsorship services to the Company. The sponsorship services allow the Company to route transactions under the Sponsoring Members’ membership to clear card transactions through card networks. Under this model, the standards of the payment networks restrict the Company from performing funds settlement and require that these funds be in the possession of the Sponsoring Member until the merchant is funded. Accordingly, settlement assets and obligations resulting from the submission of settlement files to the network or cash received from the network in advance of funding the network are the responsibility of the Sponsoring Member and are not recorded on the Company’s unaudited Condensed Consolidated Balance Sheets. Direct Member Model The Company’s European and U.K. business (previously known as Finaro) operates as a full acquirer and without a sponsor bank. Under the direct member model, the Company’s Consolidated Balance Sheets include settlement assets and liabilities that represent balances arising from the settlement process which involves the transferring of funds between card issuers, payment networks, processors, and merchants, as well as collateral held to manage merchant credit risk. As a processor, the Company facilitates the clearing and settlement activity for the merchant and records settlement assets and liabilities on the Consolidated Balance Sheets upon processing a payment transaction. Settlement assets represent cash received or amounts receivable primarily from payment networks or bank partners. Settlement liabilities primarily represent amounts payable to merchants. Settlement assets are in excess of Settlement liabilities due to prefunding provided to certain merchants. Amounts included on the unaudited Condensed Consolidated Balance Sheets as Collateral held by card networks relate to collateral required by the card networks to operate as a direct member. Recent Accounting Pronouncements Accounting Pronouncements Adopted In June 2022, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2022-03, Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions , to clarify that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring the fair value of the equity security. ASU 2022-03 also clarifies that an entity cannot recognize and measure a contractual sale restriction as a separate unit of account. The amendments in ASU 2022-03 became effective for the Company on January 1, 2024 on a prospective basis. The adoption did not have a significant impact on the Company’s unaudited condensed consolidated financial statements. Accounting Pronouncements Not Yet Adopted In November 2024, the FASB issued ASU 2024-03, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Topic 220): Disaggregation of Income Statement Expenses, which requires additional disclosure of certain amounts included in the expense captions presented on the Statements of Operations as well as disclosures about selling expenses. ASU 2024-03 is effective on a prospective basis, with the option for retrospective application, for annual periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027, with early adoption permitted. The Company is in the process of assessing the impact the adoption of this guidance will have on the Company’s f inancial statement disclosures . In December 2023, the FASB issued ASU 2023-09, Income Taxes: Improvements to Income Tax Disclosures , which provides qualitative and quantitative updates to the rate reconciliation and income taxes paid disclosures, among others, in order to enhance the transparency of income tax disclosures, including consistent categories and greater disaggregation of information in the rate reconciliation and disaggregation by jurisdiction of income taxes paid. ASU 2023-09 is effective on a prospective basis, with the option for retrospective application, for annual periods beginning after December 15, 2024 , with early adoption permitted. The Company does not plan to early adopt ASU 2023-09 and is evaluating the impact of the amendments on the Company’s unaudited condensed consolidated financial statements.

Business Combination, Asset Acquisition, and Joint Venture Formation [Abstract]
Acquisitions	Acquisitions Each of the following acquisitions was accounted for as a business combination using the acquisition method of accounting. The respective purchase prices were allocated to the assets acquired and liabilities assumed based on the estimated fair values at the date of acquisition. The excess of the purchase price over the fair value of the net assets acquired was allocated to goodwill and represents the future economic benefits arising from other assets acquired, which cannot be individually identified or separately recognized. Vectron On June 14, 2024, the Company acquired a majority stake in Vectron Systems AG (“Vectron”). Based in Germany, Vectron is a supplier of POS systems to the restaurant and hospitality verticals that management believes will provide the Company with local product expertise and a European distribution network of POS resellers. Throughout the remainder of June and July 2024, the Company purchased additional shares of Vectron’s common stock through a public tender offer and open market purchases. As of September 30, 2024, the Company owned approximately 75% of Vectron’s common stock, for which it paid $62.7 million of total purchase consideration, net of cash acquired. The Company is in the process of gaining operational control of Vectron via a domination and profit and loss transfer agreement (DPLTA). The Company consolidates 100% of Vectron’s assets, liabilities, revenues and expenses and records a noncontrolling interest balance for the 25% economic interest in Vectron not held by the Company. Total purchase consideration was as follows: Cash $ 66.9 Contingent consideration (a) 2.9 Total purchase consideration 69.8 Less: cash acquired (7.1) Total purchase consideration, net of cash acquired 62.7 Noncontrolling interest as of September 30, 2024 24.9 Fair value of net assets acquired $ 87.6 (a) The Company agreed to a cash earnout due to certain former shareholders of Vectron based on the achievement against certain operational metrics through 2027. The actual earn out can range between zero and €7.0 million. The fair value of the earnout was included in the initial purchase consideration and will be revalued and recorded quarterly until the end of the earnout period as a fair value adjustment within “Revaluation of contingent liabilities” in the Company’s unaudited Condensed Consolidated Statements of Operations. As of September 30, 2024, the fair value of the earnout was $3.1 million, which is recognized in “Other noncurrent liabilities” on the Company’s unaudited Condensed Consolidated Balance Sheets. The following table summarizes the fair value assigned to the assets acquired and liabilities assumed at the acquisition date. These amounts reflect various preliminary fair value estimates and assumptions, and are subject to change within the measurement period as valuations are finalized. The primary area of preliminary purchase price allocation subject to change relates to the valuation of accounts receivable, prepaid expenses and other current assets, other intangible assets, accounts payable, accrued expenses and other current liabilities, and residual goodwill. Accounts receivable $ 8.2 Inventory 3.5 Prepaid expenses and other current assets 6.3 Goodwill (a) 80.8 Other intangible assets 30.0 Property, plant and equipment, net 1.5 Right-of-use assets 8.9 Other noncurrent assets 2.5 Accounts payable (4.3) Accrued expenses and other current liabilities (6.5) Deferred revenue (4.6) Current lease liabilities (1.2) Deferred tax liabilities (11.4) Noncurrent lease liabilities (7.9) Other noncurrent liabilities (b) (18.2) Net assets acquired $ 87.6 (a) Goodwill is not deductible for tax purposes. (b) In connection with the Company’s majority stake in Vectron and due to Vectron’s acquisition of Acardo Group AG (“Acardo”) in December 2022, the Company became party to an earnout agreement with certain former shareholders of Acardo. The earnout is payable in multiple tranches, with up to €25.0 million payable in 2026. This amount is based on a multiple of the average of Acardo’s earnings before interest and taxes (“EBIT”) achieved in 2024 and 2025. Additionally, a percentage of Acardo’s net income for fiscal years 2023, 2024 and 2025 are payable in 2024, 2025 and 2026, respectively. Each portion of the earnout is expected to be paid in cash. The fair value of the earnout was included in the initial purchase consideration and will be revalued quarterly until the end of the earnout period as a fair value adjustment within “Revaluation of contingent liabilities” in the Company’s unaudited Condensed Consolidated Statements of Operations. As of September 30, 2024, the fair value of the earnout was $15.1 million, which was recognized in “Other noncurrent liabilities” on the Company’s unaudited Condensed Consolidated Balance Sheets. The fair values of other intangible assets were estimated using inputs classified as Level 3 under the income approach using the relief-from-royalty method for acquired technology and the trade name, and the multi-period excess earnings method for merchant relationships. This transaction was not taxable for income tax purposes. The estimated life of acquired technology, merchant relationships and trade name are six twelve The acquisition of Vectron did not have a material impact on the Company’s unaudited condensed consolidated financial statements. Revel On June 13, 2024, the Company completed the acquisition of Revel Systems, Inc. (“Revel”) by acquiring 100% of its common stock for $245.3 million of total purchase consideration, net of cash acquired. Revel offers a cloud-based POS system primarily for multi-location merchants, focusing on restaurants, as well as back office and marketing tools that management believes will strengthen the Company’s presence within the restaurant and retail markets. Total purchase consideration was as follows: Cash $ 255.3 Total purchase consideration 255.3 Less: cash acquired (10.0) Total purchase consideration, net of cash acquired $ 245.3 The following table summarizes the fair value assigned to the assets acquired and liabilities assumed at the acquisition date. These amounts reflect various preliminary fair value estimates and assumptions, and are subject to change within the measurement period as valuations are finalized. The primary area of preliminary purchase price allocation subject to change relates to the valuation of accounts receivable, prepaid expenses and other current assets, other intangible assets, accounts payable, accrued expenses and other current liabilities, and residual goodwill. Accounts receivable $ 8.7 Inventory 1.8 Prepaid expenses and other current assets 4.3 Right-of-use assets 1.5 Goodwill (a) 123.9 Other intangible assets 118.9 Deferred tax assets 7.9 Other noncurrent assets 0.3 Accounts payable (6.5) Accrued expenses and other current liabilities (7.8) Deferred revenue (6.1) Current lease liabilities (0.6) Noncurrent lease liabilities (1.0) Net assets acquired $ 245.3 (a) Goodwill is not deductible for tax purposes.

Revenue

Revenue	Sep. 30, 2024
Revenue from Contract with Customer [Abstract]
Revenue	Revenue The Company’s revenue is comprised primarily of payments-based revenue which includes fees for payment processing and gateway services. Payment processing fees are primarily driven as a percentage of payment volume. The Company also generates revenues from recurring fees which are based on the technology deployed to the merchant. Under ASC 606, the Company typically has three separate performance obligations under its recurring software as a service (“SaaS”) agreements for point-of-sale systems provided to merchants: (1) point-of-sale software, (2) lease of hardware and (3) other support services. Disaggregated Revenue The following table presents a disaggregation of the Company’s revenue from contracts with customers based on similar operational characteristics: Three Months Ended September 30, Nine Months Ended September 30, 2024 2023 2024 2023 Payments-based revenue $ 806.8 $ 626.9 $ 2,217.7 $ 1,738.0 Subscription and other revenues 102.4 48.5 225.9 121.4 Total $ 909.2 $ 675.4 $ 2,443.6 $ 1,859.4 Substantially all of the Company’s revenue is recognized over time. Contract Liabilities The Company charges merchants for various post-contract license support and service fees. These fees typically relate to a period of one year. The Company recognizes the revenue on a straight-line basis over its respective period. As of September 30, 2024 and December 31, 2023, the Company had deferred revenue of $23.1 million and $22.5 million, respectively. The change in the contract liabilities was primarily the result of a timing difference between payment from the customer and the Company’s satisfaction of each performance obligation. The amount of gross revenue recognized that was included in the December 31, 2023 balance of deferred revenue was $3.6 million and $20.8 million for the three and nine months ended September 30, 2024, respectively. Allowance for Doubtful Accounts The change in the Company’s allowance for doubtful accounts was as follows: Nine Months Ended September 30, 2024 2023 Beginning balance $ 22.7 $ 18.1 Additions to expense 6.4 7.4 Write-offs, net of recoveries and other adjustments (5.6) (3.5) Ending balance $ 23.5 $ 22.0

Future principal payments As of September 30, 2024, future principal payments associated with the Company’s long-term debt were as follows: 2024 $ — 2025 690.0 2026 450.0 2027 632.5 Thereafter 1,100.0 Total $ 2,872.5 Senior Notes due 2032 In August 2024, the Company’s subsidiaries Shift4 Payments, LLC and Shift4 Payments Finance Sub, Inc. (together, the “Issuers”) issued an aggregate of $1,100.0 million principal amount of 6.750% Senior Notes due 2032 (the “2032 Senior Notes”). The Company received net proceeds, after deducting initial purchasers’ discounts and estimated offering expenses, of approximately $1,088.7 million from the 2032 Senior Notes offering. The 2032 Senior Notes mature on August 15, 2032, and accrue interest at a rate of 6.750% per year. Interest on the 2032 Senior Notes is payable semi-annually in arrears on each February 15 and August 15, commencing on February 15, 2025. Prior to August 15, 2027, the Issuers may redeem all or a portion of the 2032 Senior Notes at a redemption price equal to 100% of the principal amount of the 2032 Senior Notes, plus the applicable make-whole premium as provided in the indenture, plus accrued and unpaid interest, if any, to, but not including, the redemption date. At any time on or after August 15, 2027, the Issuers may redeem all or a portion of the 2032 Senior Notes at the redemption prices set forth in the indenture governing the 2032 Senior Notes, plus accrued and unpaid interest to, but not including, the redemption date.

The Issuers may make such redemption so long as, after giving effect to any such redemption, at least 50% of the original aggregate principal amount of the 2032 Senior Notes (including any additional 2032 Senior Notes) remains outstanding (unless all 2032 Senior Notes are redeemed concurrently) and such redemption is effected upon not less than 10 days nor more than 60 days prior notice to the holders of the 2032 Senior Notes. The 2032 Senior Notes have not been registered under the Securities Act of 1933, as amended (“the Securities Act”), or the securities laws of any other jurisdiction. The 2032 Senior Notes were sold to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A and outside the U.S. pursuant to Regulation S of the Securities Act. Revolving Credit Facility Second Amended and Restated Revolving Credit Facility In September 2024, Shift4 Payments, LLC (the “Borrower”) entered into a Second Amended and Restated First Lien Credit Agreement (the “Credit Agreement”), providing for a $450.0 million senior secured revolving credit facility (“Revolving Credit Facility”), $112.5 million of which is available for the issuance of letters of credit. The Credit Agreement amended, restated and replaced the Borrower’s prior Amended and Restated First Lien Credit Agreement, entered into on January 29, 2021, as amended, and refinanced the $100.0 million revolving credit facility thereunder. The Company capitalized approximately $4.2 million of financing fees in connection with this refinancing. Loans incurred under the Revolving Credit Facility bear interest a rate per annum equal to, at the Borrower’s option, either (i) a term SOFR based rate (subject to a 0.0% floor), plus a margin of 2.00% per annum, or (ii) an alternate base rate (equal to the highest of the Federal Funds Effective Rate plus 0.50%, the term SOFR rate for an interest period of one month (subject to a 0.0% floor) plus 1.00%, and the prime rate announced by the administrative agent from time to time), plus a margin of 1.00% per annum. The Revolving Credit Facility matures on September 5, 2029. The Credit Agreement requires periodic interest payments until maturity on any outstanding amounts borrowed. In addition, the Borrower is required to pay a commitment fee under the Revolving Credit Facility in respect of the unutilized commitments thereunder at a rate of 0.25% per annum. The Borrower is also subject to customary letter of credit and agency fees. There were no borrowings and borrowing capacity on the Revolving Credit Facility was $450.0 million as of September 30, 2024. Restrictions and Covenants The 2025 Convertible Notes, 2026 Senior Notes, 2027 Convertible Notes, 2032 Senior Notes (collectively, the “Notes”) and Revolving Credit Facility include certain restrictions on the ability of Shift4 Payments, LLC to make loans, advances, or pay dividends to Shift4 Payments, Inc.

Fair Value Measurement

Fair Value Measurement	Sep. 30, 2024
Fair Value Disclosures [Abstract]
Fair Value Measurement	Fair Value Measurement U.S. GAAP defines a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The Company determines the fair values of its assets and liabilities that are recognized or disclosed at fair value in accordance with the hierarchy described below. The following three levels of inputs may be used to measure fair value: • Level 1—Quoted prices in active markets for identical assets or liabilities; • Level 2—Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and • Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include items where the determination of fair value requires significant management judgment or estimation. The Company makes recurring fair value measurements of contingent liabilities arising from certain acquisitions and residual commission buyouts using Level 3 unobservable inputs. Contingent liabilities for residual commission buyouts are expected earnout payments related to the number of existing point-of-sale merchants that convert to full acquiring merchants. Contingent liabilities included in the purchase price of an acquisition are based on achievement of specified performance metrics as defined in the purchase agreement. Acquisition-Related Contingent Consideration The Company’s acquisitions often include contingent consideration, or earnout, provisions. The total fair value of contingent consideration related to the acquisitions of Vectron, Finaro, and Online Payments Group as of September 30, 2024 was $54.2 million, of which $35.0 million is included in “Accrued expenses and other current liabilities” and $19.2 million is included within “Other noncurrent liabilities” on the Company’s unaudited Condensed Consolidated Balance Sheets. The balance as of September 30, 2024 is inclusive of the contingent consideration agreement Vectron was party to related to its purchase of Acardo. The change in fair value of these liabilities is included in “Revaluation of contingent liabilities” on the Company’s unaudited Condensed Consolidated Statements of Operations. Each of these fair value measurements utilize Level 3 inputs, such as projected revenues, discount rates and other subjective inputs. See Note 2 for further information on the contingent consideration for Vectron. Online Payments Group The Company entered into an earnout agreement with the former shareholders of Online Payments Group, not to exceed $60.0 million, with $30.0 million of the earnout payable as of September 2023 (“Tranche 1”) if key customers of Online Payments Group contribute a specified amount of revenue from September 29, 2022 to September 28, 2023 and the remaining $30.0 million payable as of September 2024 (“Tranche 2”) if key customers contribute a specified amount of revenue from September 29, 2022 to September 28, 2024. Each portion of the earnout will be paid 50% in shares of the Company’s Class A common stock and 50% in cash. The fair value of the earnout was included in the initial purchase consideration and was revalued quarterly until the end of the earnout period as a fair value adjustment within “Revaluation of contingent liabilities” in the Company’s unaudited Condensed Consolidated Statements of Operations. Tranche 1 was fully earned and paid in 2023. As of September 28, 2024 it was determined that 100% of the Tranche 2 payment was earned. The fair value of Tranche 2 as of September 30, 2024 was estimated to be $29.0 million (net of certain discounts) and is included in “Accrued expenses and other current liabilities” on the Company’s unaudited Condensed Consolidated Balance Sheets as of September 30, 2024. The table below provides a reconciliation of the beginning and ending balances for the Level 3 contingent liabilities: Nine Months Ended September 30, 2024 Contingent Liabilities for Acquisitions Contingent Liabilities for Assets Acquired Total Contingent Liabilities Balance at beginning of period $ 32.2 $ 1.4 $ 33.6 Contingent consideration 18.9 — 18.9 Fair value adjustments 3.9 0.3 4.2 Impact of foreign exchange 1.2 — 1.2 Contingent liabilities that achieved earnout (2.0) (1.7) (3.7) Balance at end of period $ 54.2 $ — $ 54.2 Fair value adjustments for contingent liabilities for acquisitions are recorded within “Revaluation of contingent liabilities” in the Company’s unaudited Condensed Consolidated Statements of Operations. There were no transfers into or out of Level 3 during the nine months ended September 30, 2024. The estimated fair value of the Company’s outstanding debt using quoted prices from over-the-counter markets, considered Level 2 inputs, was as follows: September 30, 2024 December 31, 2023 Carrying Fair Carrying Fair 2032 Senior Notes $ 1,085.7 $ 1,150.2 $ — $ — 2025 Convertible Notes 686.1 841.5 683.6 766.5 2027 Convertible Notes 625.3 650.5 623.5 593.2 2026 Senior Notes 445.3 445.9 443.7 438.2 Total $ 2,842.4 $ 3,088.1 $ 1,750.8 $ 1,797.9 (a) Carrying value excludes unamortized debt issuance costs related to the Revolving Credit Facility of $4.4 million and $0.6 million as of September 30, 2024 and December 31, 2023, respectively. The estimated fair value of the Company’s investments in non-marketable equity securities was $78.9 million and $62.2 million as of September 30, 2024 and December 31, 2023, respectively. These non-marketable equity investments have no readily determinable fair values and are measured using the measurement alternative, which is defined as cost, less impairment, adjusted for observable price changes from orderly transactions for identical or similar investments of the same issuer. Adjustments for these investments, if any, are recorded in “Unrealized gain on investments in securities” on the Company’s unaudited Condensed Consolidated Statements of Operations. The Company recognized fair value adjustments to its non-marketable equity investments of $10.8 million and $21.6 million for the three and nine months ended September 30, 2024, respectively, the entire amount of which related to securities still held as of September 30, 2024, based primarily on secondary offerings of identical securities by the respective companies in 2024. The Company has recognized cumulative fair value adjustments to its non-marketable equity investments of $48.9 million. The estimated fair value of the Company’s crypto settlement assets and crypto settlement liabilities was $5.0 million and $3.5 million as of September 30, 2024 and December 31, 2023, respectively. The Company has valued the assets and liabilities using quoted prices from active cryptocurrency exchanges for the underlying crypto assets, considered Level 2 inputs.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company holds an economic interest in Shift4 Payments, LLC and consolidates its financial position and results. The remaining ownership of Shift4 Payments, LLC not held by the Company is considered a noncontrolling interest. Shift4 Payments, LLC is treated as a partnership for income tax reporting and its members, including the Company, are liable for federal, state, and local income taxes based on their share of the LLC’s taxable income. In addition, Shift4 Payments, LLC wholly owns various U.S. and foreign subsidiaries which are taxed as corporations for tax reporting. Taxable income or loss from these subsidiaries is not passed through to Shift4 Payments, LLC. Instead, such taxable income or loss is taxed at the corporate level subject to the prevailing corporate tax rates. The Company’s effective tax rate was (135)% and (223)% for the three and nine months ended September 30, 2024. The Company’s effective tax rate was 2% and (6)% for the three and nine months ended September 30, 2023, respectively. The effective tax rate for the three and nine months ended September 30, 2024 was different than the U.S. federal statutory income tax rate of 21% primarily due to the $283.8 million discrete tax benefit related to the valuation allowance release and resulting additional deferred tax assets related to the TRA liability on Shift4 Payments, Inc., the net income allocated to the noncontrolling interest, and a $12.2 million tax benefit related to the valuation allowance release on certain corporate subsidiaries. The effective tax rate for the three and nine months ended September 30, 2023 was different than the U.S. federal statutory income tax rate of 21% primarily due to the net income allocated to the noncontrolling interest and the full valuation allowances on Shift4 Payments, Inc. and certain corporate subsidiaries in the U.S. In addition, the nine months ended September 30, 2023 includes a $4.8 million tax benefit related to the valuation allowance release due to a legal entity restructuring and a $1.5 million tax benefit related to the valuation allowance release due to acquired deferred tax liabilities from Focus POS Systems (“Focus”). In prior periods, the Company maintained a full valuation allowance on the net deferred tax assets of Shift4 Payments, Inc. which are comprised primarily of differences in the book and tax basis of Shift4 Payments, Inc.’s investment in Shift4 Payments, LLC. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income sufficient to utilize the deferred tax assets on income tax returns. In prior periods, management had determined that its net deferred tax assets were not more likely than not going to be realized due to existence of significant negative evidence that the Company was in a three-year cumulative loss position. Considering this and other factors, Shift4 Payments, Inc.’s full valuation allowance was maintained through the period ended June 30, 2024. During the three months ended September 30, 2024, management assessed the realizability of deferred tax assets and concluded that it is more likely than not that its net deferred tax assets will be realized and that a full valuation allowance is no longer required. The assessment included the fact that as of September 30, 2024, the Company is no longer in a three-year cumulative loss position and is projecting sufficient income in future periods to realize its deferred tax assets. The Company continues to maintain a valuation allowance on the portion of deferred tax assets that require capital gains income because there are no current projections of capital gains income at this time. Accordingly, a discrete tax benefit of $283.8 million was recognized during the period ended September 30, 2024, relating to the release of the valuation allowance associated with the Company’s deferred tax assets and recording additional deferred tax assets related to the TRA liability. Uncertain Tax Positions The effects of uncertain tax positions are recognized in the Company’s unaudited condensed consolidated financial statements if these positions meet a “more-likely-than-not” threshold. For those uncertain tax positions that are recognized in the condensed consolidated financial statements, liabilities are established to reflect the portion of those positions it cannot conclude “more-likely-than-not” to be realized upon ultimate settlement. The Company’s policy is to recognize interest and penalties related to unrecognized tax benefits within “Income tax benefit (expense)” in the Company’s unaudited Condensed Consolidated Statements of Operations. Accrued interest and penalties, if any, are included within “Deferred tax liability” in the Company’s unaudited Condensed Consolidated Balance Sheets. As of September 30, 2024 and December 31, 2023 , $7.5 million and $4.7 million, respectively, of uncertain tax positions were recognized within “Other noncurrent liabilities” in the Company’s unaudited Condensed Consolidated Balance Sheets, which were primarily recognized in conjunction with acquisitions. Tax Receivable Agreement The Company expects to obtain an increase in its share of the tax basis in the net assets of Shift4 Payments, LLC as LLC Interests are redeemed from or exchanged by the Continuing Equity Owners, at the option of the Company, determined solely by the Company’s independent directors. The Company intends to treat any redemptions and exchanges of LLC Interests as direct purchases of LLC Interests for U.S. federal income tax purposes. These increases in tax basis may reduce the amounts that it would otherwise pay in the future to various tax authorities. In connection with the Company’s initial public offering in June 2020 and certain organizational transactions that the Company effected in connection with it, the Company entered into the TRA with the Continuing Equity Owners. The TRA provides for the payment by Shift4 Payments, Inc. of 85% of the amount of any tax benefits the Company actually realizes, or in some cases is deemed to realize, as a result of (i) increases in the Company’s share of the tax basis in the net assets of Shift4 Payments, LLC resulting from any redemptions or exchanges of LLC Interests, (ii) tax basis increases attributable to payments made under the TRA, and (iii) deductions attributable to imputed interest pursuant to the TRA. The Company expects to benefit from the remaining 15% of any of cash savings that it realizes. As of September 30, 2024 and December 31, 2023, the Company recognized a TRA liability of $370.1 million and $5.1 million, respectively, after concluding it was probable that, based on estimates of future taxable income, the Company will realize tax benefits associated with the TRA. A payment of $1.7 million was made to the Continuing Equity Owners pursuant to the TRA during the nine months ended September 30, 2024. No payments were made to the Continuing Equity Owners pursuant to the TRA during the nine months ended September 30, 2023 . The estimation of liability under the TRA is by its nature imprecise and subject to significant assumptions regarding the amount, character, and timing of the taxable income of Shift4 Payments, Inc. in the future. Changes in tax laws or rates could also materially impact the estimated liability. If Rook were to exchange any of its LLC Interests subsequent to September 30, 2024, such exchanges could generate additional deferred tax assets and TRA liability. As of September 30, 2024, the estimated impact of the exchange of all of Rook’s LLC Interests was an additional deferred tax asset of approximately $523 million and a TRA liability of approximately $444 million. Organisation for Economic Co-operation and Development (“OECD”) - Pillar Two In December 2021, the Organisation for Economic Co-operation and Development issued model rules for a new global minimum tax framework (“Pillar Two”), and various governments around the world have passed, or are in the process of passing, legislation on this. Certain Pillar Two rules take effect in 2024 and 2025, depending on whether a particular jurisdiction has integrated the legislation into local law. The Company is continuing to monitor these impacts on its operating footprint and anticipates an increase in income tax expense associated with jurisdictions that have implemented an income inclusion rule or a Qualifying Minimum Top-up Tax (“QDMTT”). The Company is continuing to monitor and assess the impacts of rules set to take effect in 2025, such as the under-taxed profits rule. The impacts of Pillar Two to the Company are subject to change based on expansion and future acquisitions within jurisdictions that the Company does not currently operate.

Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions The Company has a service agreement with Jared Isaacman, the Company’s Chief Executive Officer and founder (“Founder”), in cluding access to aircrafts and a property. Total expense for this service, which is included in “General and administrative expenses” in the Company’s unaudited Condensed Consolidated Statements of Operations, was $0.2 million and $0.7 million for the three and nine months ended both September 30, 2024, and 2023. There were no amounts outstanding at September 30, 2024 or December 31, 2023. In addition, during the nine months ended September 30, 2024, the Company made $6.6 million of distributions related to income taxes paid on behalf of Rook, which are included in “Distributions to noncontrolling interests” in the Company’s unaudited Condensed Consolidated Statements of Cash Flows. In November 2021, the Company implemented a one-time discretionary equity award program for non-management employees. The Founder agreed to fund 50% of this program through a contribution of shares of his Class C common stock. As of September 30, 2024, the expected contribution from the Founder totaled 574,428 shares of his Class C common stock. The one-time discretionary equity award program will vest in three Rook has entered into margin loan agreements, pursuant to which, in addition to other collateral, it has pledged LLC Interests and shares of the Company’s Class A and Class B common stock (collectively, “Rook Units”) to secure a margin loan. If Rook were to default on its obligations under the margin loan and fail to cure such default, the lender would have the right to exchange and sell up to 15,000,000 Rook units to satisfy Rook’s obligation. In September 2021, the Founder, through a wholly-owned special purpose vehicle (“SPV”), entered into two variable prepaid forward contracts (“VPF Contracts”) with an unaffiliated dealer (“Dealer”), one covering approximately 2.18 million shares of the Company’s Class A common stock and the other covering approximately 2.26 million shares of the Company’s Class A common stock. The VPF Contracts both fully settled pursuant to their terms on specified dates in June, July, August and September 2024, at which time the actual number of shares of the Company’s Class A common stock to be delivered by the SPV was determined based on the price of the Company’s Class A common stock on such dates relative to the forward floor price of approximately $66.424 per share and the forward cap price of approximately $112.09 per share for the contract covering approximately 2.18 million shares of the Company’s Class A common stock, and to the forward floor price of $66.424 per share and the forward cap price of approximately $120.39 per share for the contract covering approximately 2.26 million shares of the Company’s Class A common stock, with the aggregate number not to exceed approximately 4.44 million shares, which is the aggregate number of shares of the Company’s Class B common stock and LLC Interests pledged by Rook to secure its obligations under the contracts. During the nine months ended September 30, 2024 , 4,030,855 shares of the Company’s Class B common stock owned by the SPV were effectively converted to Class A common stock and delivered to the SPV through the VPF Contracts.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies From time to time, the Company may become involved in various lawsuits and legal proceedings, which arise in the ordinary course of business. However, litigation is subject to inherent uncertainties, and an adverse result in these, or other matters, may arise from time to time that may harm the Company’s business. On August 18, 2023, a shareholder filed a putative securities class action against the Company and certain of its current and former executive officers in the U.S. District Court for the Eastern District of Pennsylvania (the “Court”), captioned O’Meara v. Shift4 Payments, Inc., et al., Case No. 5:23-cv-03206-JFL (the “O’Meara Action”). Plaintiff O’Meara seeks to represent purchasers of the Company’s securities between November 10, 2021 and April 18, 2023. On October 13, 2023, another shareholder represented by the same law firm as O’Meara filed a similar complaint against the same defendants in the Court, captioned Baer v. Shift4 Payments, Inc., et al., Case No. 5:23-cv-03969-JFL (the “Baer Action”). Plaintiff Baer seeks to represent purchasers of the Company’s securities between June 5, 2020, and April 18, 2023. Both complaints allege violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 promulgated thereunder, based on allegedly false and misleading statements about the Company’s business, operations, and compliance policies, and both seek unspecified damages. On October 19, 2023, Plaintiff Baer filed a motion to consolidate the O’Meara Action and the Baer Action and appoint Baer as lead plaintiff. On November 3, 2023, the Court consolidated the O’Meara and Baer Actions and appointed Plaintiff Baer as the lead plaintiff in the consolidated action. Lead Plaintiff Baer and Plaintiff O’Meara filed an amended complaint on January 5, 2024, purportedly brought on behalf of purchasers of the Company’s securities between June 5, 2020 and April 18, 2023, and alleging violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 promulgated thereunder, based on allegedly false and misleading statements about the Company’s business, operations, and compliance policies. The Company moved to dismiss the consolidated amended complaint on February 19, 2024. The Court granted the Company’s motion to dismiss on August 14, 2024, with leave to amend. Lead Plaintiff Baer filed a second amended complaint on September 3, 2024, alleging violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 promulgated thereunder purportedly on behalf of purchasers of the Company’s securities between June 5, 2020 and October 21, 2022. The Company filed a motion to dismiss on October 1, 2024. A hearing is not yet scheduled on the Company’s motion to dismiss. The Company disputes the allegations in the above-referenced matters, intends to defend the matters vigorously, and believes that the claims are without merit. Certain legal and regulatory proceedings, such as the above-referenced matters, may be based on complex claims involving substantial uncertainties and unascertainable damages. Accordingly, it is not possible to determine the probability of loss or estimate damages for any of the above matters, and therefore, the Company has not established reserves for any of these proceedings. When the Company determines that a loss is both probable and reasonably estimable, the Company records a liability, and, if the liability is material, discloses the amount of the liability reserved. Given that such proceedings are subject to uncertainty, there can be no assurance that such legal proceedings, either individually or in the aggregate, will not have a material adverse effect on our business, results of operations, financial condition or cash flows. The Company is currently not aware of any legal proceedings or claims other than those described above that the Company believes could have a material adverse effect on its business, financial condition or operating results.

The Company may also, from time to time, enter into Rule 10b5-1 plans to facilitate repurchases of its shares pursuant to the May 2024 Program. The May 2024 Program does not obligate the Company to acquire any particular amount of common stock. The May 2024 Program may be extended, modified, suspended or discontinued at any time at the Company’s discretion. During the nine months ended September 30, 2024, the Company repurchased 528,888 shares of Class A common stock for $35.9 million, including commissions paid, at an average price paid of $67.77 per share.

These shares will be issued over the course of 2024, in accordance with the terms of the acquisition. Rook has the right to require the Company to redeem its LLC Interests for, at the option of the Company, determined solely by the Company’s independent directors, newly-issued shares of Class A common stock on a one-for-one basis or a cash payment equal to a volume weighted average market price of one share of Class A common stock for each LLC Interest redeemed. In connection with the exercise of the redemption or exchange of LLC Interests, (1) Rook will be required to surrender a number of shares of Class B common stock, which the Company will cancel for no consideration on a one-for-one basis with the number of LLC Interests so redeemed or exchanged and (2) Rook will surrender LLC Interests to Shift4 Payments, LLC for cancellation.

The acquisition was accounted for as a business combination under ASC 805. The Company consolidates 100% of Vectron’s assets, liabilities, revenues and expenses. The noncontrolling interests balance represents the 25% economic interest in Vectron not held by the Company, which amounted to $25.7 million as of September 30, 2024 and was calculated as the number of shares of Vectron’s common stock not owned by the Company, multiplied by the price per share of Vectron’s common stock as of the acquisition date.

Basic and Diluted Net Income per Share	Sep. 30, 2024
Earnings Per Share [Abstract]
Basic and Diluted Net Income per Share	Basic and Diluted Net Income per Share Basic net income per share has been computed by dividing net income attributable to common shareholders by the weighted average number of shares of common stock outstanding for the same period. Shares issued during the period and shares reacquired during the period are weighted for the portion of the period in which the shares were outstanding. Diluted net income per share has been computed in a manner consistent with that of basic net income per share while giving effect to all shares of potentially dilutive common stock that were outstanding during the period. The following table presents the calculation of basic and diluted net income per share under the two-class method. Three Months Ended September 30, Nine Months Ended September 30, 2024 2023 2024 2023 Net income $ 72.2 $ 46.5 $ 155.2 $ 103.7 Less: Net income attributable to noncontrolling interests (18.4) (13.9) (41.6) (31.2) Adjustment to net income attributable to common stockholders (0.4) — (1.1) — Net income attributable to common stockholders - basic 53.4 32.6 112.5 72.5 Reallocation of net income from noncontrolling interests to common stockholders due to effect of dilutive securities 14.2 0.2 32.1 0.5 Net income attributable to common stockholders - diluted $ 67.6 $ 32.8 $ 144.6 $ 73.0 Numerator - allocation of net income attributable to common stockholders: Net income allocated to Class A common stock - basic $ 52.1 $ 31.6 $ 109.7 $ 70.0 Reallocation of net income from noncontrolling interests to common stockholders due to effect of dilutive securities 14.2 0.2 32.2 0.5 Net income allocated to Class A common stock - diluted $ 66.3 $ 31.8 $ 141.9 $ 70.5 Net income allocated to Class C common stock - basic $ 1.3 $ 1.0 $ 2.8 $ 2.5 Reallocation of net income from noncontrolling interests to common stockholders due to effect of dilutive securities — — (0.1) — Net income allocated to Class C common stock - diluted $ 1.3 $ 1.0 $ 2.7 $ 2.5 Denominator: Weighted average shares of Class A common stock outstanding - basic (a) 66,791,329 56,537,008 65,230,377 56,233,959 Effect of dilutive securities: LLC Interests 21,216,195 — 22,953,032 — RSUs 1,349,414 873,107 1,331,271 1,200,466 Contingent shares — 262,968 — 262,968 Weighted average shares of Class A common stock outstanding - diluted 89,356,938 57,673,083 89,514,680 57,697,393 Weighted average shares of Class C common stock outstanding - basic and diluted 1,659,314 1,759,273 1,681,264 2,019,063 Net income per share - Basic: Class A common stock $ 0.78 $ 0.56 $ 1.68 $ 1.24 Class C common stock $ 0.78 $ 0.56 $ 1.68 $ 1.24 Net income per share - Diluted: Class A Common Stock $ 0.74 $ 0.55 $ 1.59 $ 1.22 Class C Common Stock $ 0.74 $ 0.55 $ 1.59 $ 1.22 (a) For the three and nine months ended September 30, 2024, included 1,253,470 shares that had been committed but not issued as of September 30, 2024.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying interim condensed consolidated financial statements of the Company are unaudited. These interim condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the U.S. (“U.S. GAAP”) and the applicable rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) for interim financial information. These fi nancial statements do not include all information and footnotes required by U.S. GAAP for complete financial statements. The December 31, 2023 Condensed Consolidated Balance Sheet was derived from audited financial statements as of that date, but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, the unaudited condensed consolidated financial statements reflect all adjustments consisting only of normal recurring adjustments necessary to state fairly the financial position, results of operations and cash flows for the periods presented in conformity with U.S. GAAP applicable to interim periods. The results of operations for the interim periods presented are not necessarily indicative of results for the full year or future periods. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the related notes thereto as of and for the fiscal year ended December 31, 2023, as disclosed in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023 (the “2023 Form 10-K”). The unaudited condensed consolidated financial statements include the accounts of Shift4 Payments, Inc. and its wholly-owned subsidiaries. Shift4 Payments, Inc. consolidates the financial results of Shift4 Payments, LLC, which is considered a variable interest entity. Shift4 Payments, Inc. is the primary beneficiary and sole managing member of Shift4 Payments, LLC and has decision making authority that significantly affects the economic performance of the entity. As a result, the Company consolidates Shift4 Payments, LLC and reports a noncontrolling interest representing the economic interest in Shift4 Payments, LLC held by Rook Holdings Inc. (“Rook”).
Change in Presentation of Consolidated Balance Sheets	Change in Presentation of Consolidated Balance Sheets Prior year balances have been adjusted to present “Current TRA liability” on its own line item rather than within “Accrued expenses and other current liabilities” on the Company’s unaudited Condensed Consolidated Balance Sheets to conform to the current period presentation. Prior year balances have been adjusted to present “Noncurrent TRA liability” on its own line item rather than within “Other noncurrent liabilities” on the Company’s unaudited Condensed Consolidated Balance Sheets to conform to the current period presentation.
Use of Estimates	Use of Estimates
Cash and Cash Equivalents and Restricted Cash	Cash and Cash Equivalents and Restricted Cash Highly liquid investments with maturities of three months or less at the date of purchase are considered to be cash equivalents and are stated at cost, which approximates fair value. The Company’s cash equivalents consist of highly liquid investments in money market funds. On September 30, 2024 the Company entered into the Settlement Line Credit Agreement (the “Settlement Line Agreement”), by and between Shift4 LLC, as the borrower, and Citizens Bank, N.A. (“Citizens”), as the lender, providing for a settlement line of credit with an aggregate available amount of up to $100.0 million (the “Settlement Line”). The purpose of the Settlement Line is to provide financing for certain settlement obligations of Shift4 LLC’s merchants and to eliminate the requirement for cash collateral under the sponsorship agreement with Citizens (the “Sponsorship Agreement”), which was amended in conjunction with the closing of the Settlement Line Agreement. There were no borrowings under the Settlement Line as of September 30, 2024. The Settlement Line is scheduled to mature on September 29, 2025, subject to extensions. Draws under the Settlement Line bear interest at a rate per annum equal to either (x) a daily simple SOFR based rate (subject to a 0.0% floor), plus an applicable margin of 0.75%, or (y) to the extent required by the Settlement Line Agreement upon the occurrence of certain specified events, an alternate base rate (equal to the highest of the Federal Funds Effective Rate plus 0.50%, the daily simple SOFR rate (subject to a 0.0% floor) plus 1.00%, and the prime rate announced by Citizens from time to time). In addition to making periodic interest payments on the principal amount of outstanding draws under the Settlement Line, the Company is required to pay an unused fee under the Settlement Line in respect of the unused availability thereunder at a rate equal to 0.15% per annum.
Settlement Assets and Liabilities	Settlement Assets and Liabilities Settlement assets and liabilities are balances related to the settlement process which involves the transferring of funds between card issuers, merchants and other third parties. The Company currently operates under two different models: (1) a sponsorship model and (2) a direct member model. In the U.S., the Company operates under the sponsorship model and outside the U.S. the Company primarily operates under the direct member model. The Company’s operations outside the U.S. are primarily related to the business of Finaro, which was acquired in the fourth quarter of 2023. Sponsorship Model In the U.S., the Company operates under the sponsorship model. In order for the Company to provide payment processing services, Visa, MasterCard and other payment networks require sponsorship by a member clearing bank. The Company has an agreement with banks and financial institutions (the “Sponsoring Member”), to provide sponsorship services to the Company. The sponsorship services allow the Company to route transactions under the Sponsoring Members’ membership to clear card transactions through card networks. Under this model, the standards of the payment networks restrict the Company from performing funds settlement and require that these funds be in the possession of the Sponsoring Member until the merchant is funded. Accordingly, settlement assets and obligations resulting from the submission of settlement files to the network or cash received from the network in advance of funding the network are the responsibility of the Sponsoring Member and are not recorded on the Company’s unaudited Condensed Consolidated Balance Sheets. Direct Member Model The Company’s European and U.K. business (previously known as Finaro) operates as a full acquirer and without a sponsor bank. Under the direct member model, the Company’s Consolidated Balance Sheets include settlement assets and liabilities that represent balances arising from the settlement process which involves the transferring of funds between card issuers, payment networks, processors, and merchants, as well as collateral held to manage merchant credit risk. As a processor, the Company facilitates the clearing and settlement activity for the merchant and records settlement assets and liabilities on the Consolidated Balance Sheets upon processing a payment transaction. Settlement assets represent cash received or amounts receivable primarily from payment networks or bank partners. Settlement liabilities primarily represent amounts payable to merchants. Settlement assets are in excess of Settlement liabilities due to prefunding provided to certain merchants. Amounts included on the unaudited Condensed Consolidated Balance Sheets as Collateral held by card networks relate to collateral required by the card networks to operate as a direct member.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Accounting Pronouncements Adopted In June 2022, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2022-03, Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions , to clarify that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring the fair value of the equity security. ASU 2022-03 also clarifies that an entity cannot recognize and measure a contractual sale restriction as a separate unit of account. The amendments in ASU 2022-03 became effective for the Company on January 1, 2024 on a prospective basis. The adoption did not have a significant impact on the Company’s unaudited condensed consolidated financial statements. Accounting Pronouncements Not Yet Adopted In November 2024, the FASB issued ASU 2024-03, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Topic 220): Disaggregation of Income Statement Expenses, which requires additional disclosure of certain amounts included in the expense captions presented on the Statements of Operations as well as disclosures about selling expenses. ASU 2024-03 is effective on a prospective basis, with the option for retrospective application, for annual periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027, with early adoption permitted. The Company is in the process of assessing the impact the adoption of this guidance will have on the Company’s f inancial statement disclosures . In December 2023, the FASB issued ASU 2023-09, Income Taxes: Improvements to Income Tax Disclosures , which provides qualitative and quantitative updates to the rate reconciliation and income taxes paid disclosures, among others, in order to enhance the transparency of income tax disclosures, including consistent categories and greater disaggregation of information in the rate reconciliation and disaggregation by jurisdiction of income taxes paid. ASU 2023-09 is effective on a prospective basis, with the option for retrospective application, for annual periods beginning after December 15, 2024 , with early adoption permitted. The Company does not plan to early adopt ASU 2023-09 and is evaluating the impact of the amendments on the Company’s unaudited condensed consolidated financial statements.

(b) In connection with the Company’s majority stake in Vectron and due to Vectron’s acquisition of Acardo Group AG (“Acardo”) in December 2022, the Company became party to an earnout agreement with certain former shareholders of Acardo. The earnout is payable in multiple tranches, with up to €25.0 million payable in 2026. This amount is based on a multiple of the average of Acardo’s earnings before interest and taxes (“EBIT”) achieved in 2024 and 2025. Additionally, a percentage of Acardo’s net income for fiscal years 2023, 2024 and 2025 are payable in 2024, 2025 and 2026, respectively. Each portion of the earnout is expected to be paid in cash. The fair value of the earnout was included in the initial purchase consideration and will be revalued quarterly until the end of the earnout period as a fair value adjustment within “Revaluation of contingent liabilities” in the Company’s unaudited Condensed Consolidated Statements of Operations. As of September 30, 2024, the fair value of the earnout was $15.1 million, which was recognized in “Other noncurrent liabilities” on the Company’s unaudited Condensed Consolidated Balance Sheets.
