Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The unaudited financial information included in this report includes the accounts of FIS and its subsidiaries prepared in accordance with U.S. generally accepted accounting principles and the instructions to Form 10-Q and Article 10 of Regulation S-X. All adjustments considered necessary for a fair presentation have been included. This report should be read in conjunction with the Company's Annual Report on Form 10-K for the year ended December 31, 2024. The preparation of these consolidated financial statements in conformity with United States ("U.S.") generally accepted accounting principles ("GAAP") and the related rules and regulations of the U.S. Securities and Exchange Commission ("SEC" or "Commission") requires our management to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, and the related disclosure of contingent assets and liabilities. The inputs into management's critical and significant accounting estimates consider the economic impact of inflation and economic growth rates. These estimates may change as new events occur and additional information is obtained. Future actual results could differ materially from these estimates. To the extent that there are differences between these estimates, judgments and assumptions and actual results, our consolidated financial statements will be affected. On January 31, 2024, the Company completed the sale ("the 2024 Worldpay Sale") of a 55% equity interest in its Worldpay Merchant Solutions business to private equity funds managed by GTCR, LLC (such funds, the "Buyer"). FIS retains a non-controlling 45% equity interest in a new standalone joint venture, Worldpay Holdco, LLC ("Worldpay"), following the closing of the 2024 Worldpay Sale. FIS' share of the net income (loss) of Worldpay is reported as Equity method investment earnings (loss), net of tax, in the consolidated statements of earnings (loss). See Note 3 for further information. The cash proceeds received by FIS, net of closing adjustments and transaction costs, are presented as investing cash flows within continuing operations in the consolidated statement of cash flows. During the third quarter of fiscal year 2023, the Company analyzed quantitative and qualitative factors relevant to the Worldpay Merchant Solutions disposal group in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 205-20 and determined that the accounting criteria to be classified as held for sale were met, when a definitive purchase agreement was signed. Accordingly, the assets and liabilities of the disposal group are presented separately on the consolidated balance sheets for periods presented prior to disposal. In addition, the disposition represents a strategic shift that will have a major impact on the Company's operations and financial results. As a result, the operating results of the Worldpay Merchant Solutions business prior to the closing of the 2024 Worldpay Sale, as well as subsequent adjustments for the resolution of related contingencies, have been reflected as discontinued operations and, as such, have been excluded from continuing operations and segment results. The Worldpay Merchant Solutions business included the former Merchant Solutions segment, in addition to a business previously included in the Corporate and Other segment, which have been reflected as discontinued operations for all periods presented prior to disposal. Accordingly, the Company no longer reports the Merchant Solutions segment; it now reports its financial performance based on the following segments: Banking Solutions ("Banking"), Capital Market Solutions ("Capital Markets") and Corporate and Other. On April 17, 2025, FIS entered into definitive agreements to (i) buy the Issuer Solutions business from Global Payments Inc. (“Global Payments”) for an enterprise value of $13.5 billion, inclusive of $1.5 billion of anticipated net present value of tax assets, or a net purchase price of $12.0 billion, subject to customary adjustments (the “Issuer Solutions Acquisition”) and (ii) sell its remaining equity interest in Worldpay to Global Payments for a value of $6.6 billion net of transaction fees and other costs (the “Worldpay Minority Interest Sale”). We expect to fund the Issuer Solutions Acquisition through a combination of approximately $8.0 billion of new debt and the after-tax proceeds from the Worldpay Minority Interest Sale. The transactions are expected to close by the first quarter of 2026, subject to regulatory approvals and other customary closing conditions. We will continue to account for our non-controlling 45% equity interest in Worldpay using the equity method of accounting until the completion of the transactions. Upon closing of the Worldpay Minority Interest Sale, we expect to record a gain equal to the excess of the estimated $6.6 billion pre-tax net selling price over the carrying value of the Worldpay equity method investment as of the date of closing, adjusted for the impact of our share of Worldpay's cumulative translation adjustments recorded in accumulated other comprehensive earnings (loss). The carrying value of the Worldpay equity method investment, which was $3.8 billion as of September 30, 2025, will continue to be adjusted for our equity method investment earnings (loss) before application of investor-level taxes and for our pro rata share of the investee's other comprehensive earnings (loss) as well as for any distributions received from our equity method investment. Certain reclassifications have been made in the 2024 consolidated financial statements to conform to the classifications used in 2025 as described below. •Revenue related primarily to software licenses requiring frequent, integral updates was classified as Transaction processing and services revenue during the quarter ended December 31, 2024, and related prior-period amounts have been reclassified from Other recurring revenue to Transaction processing and services for comparability. See Note 5 for further information. •In the consolidated statements of cash flows, we reclassified Coupon payments on interest rate swaps from Other investing activities into its own classification. The consolidated statement of cash flows for the nine months ended September 30, 2024, has been reclassified to conform to the current presentation. Amounts in tables in the financial statements and accompanying footnotes may not sum or calculate due to rounding. Revision of Prior-Period Consolidated Financial Statements During the third quarter of 2024, the Company identified immaterial misstatements affecting the Company's previously issued consolidated financial statements as of and for the annual periods ended December 31, 2023 and 2022, and the quarterly periods ended March 31 and June 30, 2024. The misstatements related primarily to the timing of the recognition of expenses associated with inventory-related accruals, along with their related balance sheet impacts, and the presentation of certain value-added tax balances in the consolidated financial statements. The Company has revised its prior-period financial statements to correct these misstatements as well as other unrelated immaterial misstatements, including adjustments to Revenue and Other income (expense), net. The revisions ensure comparability across all periods reflected herein. Recently Adopted Accounting Guidance No recently adopted accounting pronouncements are expected to have a material impact on our consolidated financial statements or disclosures. Recent Accounting Guidance Not Yet Adopted In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The ASU requires that an entity disclose specific categories in the effective tax rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. The ASU also introduces requirements for disaggregated disclosures of federal, state and foreign income tax expense and taxes paid. The amendments are effective for fiscal years beginning after December 31, 2024, and should be applied prospectively, although retrospective application is permitted. The Company will adopt the amendments on an annual basis beginning with the current fiscal year. These amendments will expand the Company’s annual income tax disclosures but will not impact the consolidated balance sheets, results of operations or cash flows. In November 2024, the FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. The ASU requires disclosure of disaggregated information about specific categories underlying certain income statement expense line items. This guidance is effective for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027. Early adoption is permitted and is effective on either a prospective basis or retrospective basis. The Company is currently evaluating the impact of adoption on our financial disclosures. In July 2025, the FASB issued ASU 2025-05, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets. The ASU provides a practical expedient that allows entities to assume conditions existing as of the balance sheet date remain unchanged over the life of the asset when estimating credit losses for current trade receivables and current contract assets arising from transactions accounted for under Topic 606. The amendments are effective for annual reporting periods beginning after December 15, 2025, and for interim periods within those annual periods, with early adoption permitted. The amendments should be applied prospectively. The Company is currently evaluating the impact of this ASU and believes that adoption will not have a material effect on the consolidated financial statements or related disclosures. In September 2025, the FASB issued ASU 2025-06, Intangibles – Goodwill and Other – Internal-use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software. This guidance updates requirements for capitalizing internal-use software costs by replacing the current stage-based model with a principles-based approach. Under the new ASU, capitalization of eligible software development costs begins when management has authorized and committed to funding the project and it is probable the project will be completed and used as intended. Entities must also consider whether significant uncertainty exists regarding the development activities. The amendments are effective for annual reporting periods beginning after December 15, 2027, including interim periods within those years. Early adoption is permitted. The amendments may be applied prospectively, on a modified retrospective basis for in-process projects, or retrospectively. The Company is currently evaluating the impact of this ASU on its consolidated financial statements and related disclosures.

All adjustments considered necessary for a fair presentation have been included. This report should be read in conjunction with the Company's Annual Report on Form 10-K for the year ended December 31, 2024.

The preparation of these consolidated financial statements in conformity with United States ("U.S.") generally accepted accounting principles ("GAAP") and the related rules and regulations of the U.S. Securities and Exchange Commission ("SEC" or "Commission") requires our management to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, and the related disclosure of contingent assets and liabilities.

FIS retains a non-controlling 45% equity interest in a new standalone joint venture, Worldpay Holdco, LLC ("Worldpay"), following the closing of the 2024 Worldpay Sale. FIS' share of the net income (loss) of Worldpay is reported as Equity method investment earnings (loss), net of tax, in the consolidated statements of earnings (loss). See Note 3 for further information. The cash proceeds received by FIS, net of closing adjustments and transaction costs, are presented as investing cash flows within continuing operations in the consolidated statement of cash flows.

In addition, the disposition represents a strategic shift that will have a major impact on the Company's operations and financial results. As a result, the operating results of the Worldpay Merchant Solutions business prior to the closing of the 2024 Worldpay Sale, as well as subsequent adjustments for the resolution of related contingencies, have been reflected as discontinued operations and, as such, have been excluded from continuing operations and segment results.

The Worldpay Merchant Solutions business included the former Merchant Solutions segment, in addition to a business previously included in the Corporate and Other segment, which have been reflected as discontinued operations for all periods presented prior to disposal. Accordingly, the Company no longer reports the Merchant Solutions segment; it now reports its financial performance based on the following segments: Banking Solutions ("Banking"), Capital Market Solutions ("Capital Markets") and Corporate and Other.

The transactions are expected to close by the first quarter of 2026, subject to regulatory approvals and other customary closing conditions.

We will continue to account for our non-controlling 45% equity interest in Worldpay using the equity method of accounting until the completion of the transactions. Upon closing of the Worldpay Minority Interest Sale, we expect to record a gain equal to the excess of the estimated $6.6 billion pre-tax net selling price over the carrying value of the Worldpay equity method investment as of the date of closing, adjusted for the impact of our share of Worldpay's cumulative translation

adjustments recorded in accumulated other comprehensive earnings (loss). The carrying value of the Worldpay equity method investment, which was $3.8 billion as of September 30, 2025, will continue to be adjusted for our equity method investment earnings (loss) before application of investor-level taxes and for our pro rata share of the investee's other comprehensive earnings (loss) as well as for any distributions received from our equity method investment.
