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, 2023. 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 and liabilities and the related disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reported periods. 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 previously announced sale ("the 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% ownership interest in a new standalone joint venture, Worldpay Holdco, LLC ("Worldpay"), following the closing of the Worldpay Sale. FIS' share of the net income (loss) of Worldpay is reported as equity method investment earnings (loss), net of tax. The net cash proceeds received by FIS, net of estimated closing adjustments and transaction costs, are presented as investing cash flows within continuing operations on the consolidated statement of cash flows. See Note 4 for information regarding the the equity method investment earnings (loss), net of tax, for the the period from February 1 through March 31, 2024. 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 all periods presented. 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 Worldpay Sale have been reflected as discontinued operations for all periods presented 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. 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. As a result of its ongoing portfolio assessments, the Company reclassified certain non-strategic operations from Banking to Corporate and Other during the quarter ended December 31, 2023. The Company recast all prior-period segment information presented to reflect these reclassifications. See Note 13 for more information regarding our segments. Certain reclassifications have been made in the 2023 consolidated financial statements to conform to the classifications used in 2024. The consolidated statements of cash flows for the three months ended March 31, 2024, are presented on a continuing operations basis, with summarized cash flows from discontinued operations for operating, investing and financing activities shown separately. The consolidated statement of cash flows for the three months ended March 31, 2023, has been reclassified to conform to the 2024 presentation.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies The Company adopted the following new significant accounting policy during the first quarter of 2024. See our Annual Report on Form 10-K for the fiscal year ended December 31, 2023, for a complete summary of our significant accounting policies. Equity Method Investment The Company reports its investments in unconsolidated entities over whose operating and financial policies the Company has the ability to exercise significant influence, but not control, under the equity method of accounting. Equity method investments are initially recorded at cost and are included in Equity method investment on the consolidated balance sheet. Under this method of accounting, the Company's pro rata share of the investee's earnings or losses is reported in Equity method investment earnings (loss), net of tax, in the consolidated statement of earnings (loss). The Company also reports its investor-level tax impact relating to equity method investments as a component of Equity method investment earnings (loss) in the consolidated statement of earnings (loss). The Company monitors its investments for other-than-temporary impairment by considering factors such as current economic and market conditions and the operating performance of the investees and records reductions in carrying values when necessary. Equity method investees are considered related parties of the Company.

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	Discontinued Operations Sale of Worldpay Merchant Solutions Business As discussed in Note 1, the Company completed the Worldpay Sale on January 31, 2024. The results of the Worldpay Merchant Solutions business prior to the completion of the Worldpay Sale have been presented as discontinued operations. The assets and liabilities of our Worldpay Brazil and RealNet subsidiaries, the value of which was included as part of the Worldpay Sale, were not conveyed in the closing and are expected to be transferred as soon as all regulatory approvals have been received. These assets and liabilities continue to be reported as assets held for sale, and their related earnings (loss) are deemed immaterial. The following table represents a reconciliation of the major components of Earnings (loss) from discontinued operations, net of tax, presented in the consolidated statements of earnings (loss), reflecting activity through January 31, 2024 (the date the Worldpay Sale closed) (in millions). The Company's presentation of earnings (loss) from discontinued operations excludes general corporate overhead costs that were historically allocated to the Worldpay Merchant Solutions business. Additionally, beginning on July 5, 2023, the Company stopped amortization of long-lived assets held for sale in accordance with ASC 360.

The Company recorded a tax benefit of $991 million primarily from the write-off of U.S. deferred tax liabilities that were not transferred in the Worldpay Sale, net of the estimated current U.S. tax cost that the Company expects to incur as a result of the Worldpay Sale and which was recorded based on available data and management determinations as of March 31, 2024. Post-closing selling price adjustments and completion of other purchase agreement provisions in connection with the Worldpay Sale could result in further adjustments to the loss on sale amount and the estimated tax impact. The following table represents the major classes of assets and liabilities of the disposal group classified as held for sale presented in the consolidated balance sheets as of March 31, 2024, and December 31, 2023 (in millions). Assets held for sale are reported at the lower of their carrying value or fair value less cost to sell and are not depreciated or amortized.

Equity Method Investments and Joint Ventures [Abstract]
Equity Method Investment	Equity Method Investment As discussed in Note 1, the Company completed the Worldpay Sale on January 31, 2024, retaining a non-controlling ownership interest in Worldpay. We account for our remaining minority ownership in Worldpay using the equity method of accounting. As of March 31, 2024, we own 45% of Worldpay. This investment is reflected in Equity method investment on our March 31, 2024, consolidated balance sheet. During the two-month period from February 1 through March 31, 2024, our share of the net income of Worldpay and our investor-level tax impact is reported as Equity method investment earnings (loss), net of tax, in the consolidated statement of earnings (loss). Summary Worldpay financial information is as follows (in millions): Two months ended March 31, 2024 Revenue $ 832 Gross profit $ 385 Earnings (loss) before income taxes $ (230) Net earnings (loss) attributable to Worldpay $ (243) FIS share of net earnings (loss) attributable to Worldpay, net of tax (1) $ (86) (1) This amount is net of $23 million of investor-level tax benefit. Continuing Involvement with Discontinued Operations and Related-Party Transactions In connection with the closing of the Worldpay Sale, the Company entered into a limited liability company operating agreement (the "LLCA") with respect to Worldpay, and a registration rights agreement with respect to the Company's retained equity interest in Worldpay. The LLCA provides that FIS has the right to appoint a minority of the board of managers of Worldpay and that FIS has customary consent and consultation rights with respect to certain material actions of Worldpay, in each case, subject to ownership stepdown thresholds. The LLCA contains, among other things, covenants and restrictions relating to other governance, liquidity and tax matters, including non-solicitation and noncompetition covenants, distribution mechanics, preemptive rights and follow-on equity funding commitments of the Buyer, and restrictions on transfer and associated tag-along and drag-along rights. Each of FIS and the Buyer will have the right to require Worldpay to consummate an initial public offering ("IPO") or sale transaction after the fourth anniversary of the closing, subject to certain return hurdles and (in the case of an IPO) public float requirements, which requirements will fall away following the sixth anniversary of the closing. We have continuing involvement with Worldpay, primarily through our remaining interest, an employee leasing agreement ("ELA"), a transition services agreement ("TSA"), and various other commercial agreements. Under the terms of the ELA, the Company is leasing certain employees to Worldpay in the United States, China, Colombia and South Korea for up to five months after the closing. The compensation and benefit costs paid by the Company for the leased employees are billed to and reimbursed by Worldpay. Under the terms of the TSA, the Company is procuring certain third-party services on behalf of Worldpay and providing technology infrastructure, risk and security, accounting and various other corporate services to Worldpay for a period of up to 24 months after the closing, subject to a six-month extension, and Worldpay is providing various corporate services to the Company, allowing it to maintain access to certain resources transferred in the Worldpay Sale. Pass-through costs under the ELA and third-party pass-through costs under the TSA of $115 million and $57 million, respectively, were incurred during the two-month period from February 1 through March 31, 2024, and netted against the equal and offsetting reimbursement amounts due from Worldpay. Additionally, during the two-month period from February 1 through March 31, 2024, net TSA services income of $33 million was recognized in Other operating (income) expense, net - related party, and the corresponding expense was recognized in Selling, general and administrative expense in the consolidated statement of earnings (loss). Income earned during the two-month period from February 1 through March 31, 2024, from various commercial services provided to Worldpay is not considered material to the Company's consolidated financial statements. For the two-month period from February 1 through March 31, 2024, we collected net cash of $136 million related to the ELA, TSA and commercial agreements with Worldpay. As of March 31, 2024, we recorded a receivable of $153 million in Receivable from related party on the consolidated balance sheet in connection with the ELA, TSA and commercial agreements. Under the ELA, amounts are generally invoiced to Worldpay on the 15th of each month for the preceding and subsequent payroll periods and are payable by wire transfer within 10 days. $48 million included in our related-party receivable as of March 31, 2024, are offset by an equal amount of accrued employee-related liabilities recorded in Accounts payable, accrued and other liabilities on the consolidated balance sheet. Upon termination of the ELA, the amount of the accrued employee-related liabilities as of the date of termination will be assumed by Worldpay in satisfaction of the corresponding receivable. Under the TSA and commercial agreements, amounts are generally invoiced monthly in arrears and are payable by electronic transfer within 30 days of invoice. As of March 31, 2024, we recorded a settlement payable of $101 million in Current assets held for sale on the consolidated balance sheet for amounts to be settled from our RealNet subsidiary to Payrix, a subsidiary of Worldpay. The settlement payable by RealNet to Payrix is generally paid to Payrix's submerchants on behalf of Payrix via ACH within five business days according to payment instructions provided by Payrix. As of March 31, 2024, we also recorded other payables to Worldpay of $43 million in Accounts payable, accrued and other liabilities on the consolidated balance sheet. These amounts are generally payable within 30 days.

Business Combination and Asset Acquisition [Abstract]
Virtus Acquisition	Virtus AcquisitionOn January 2, 2020, FIS acquired a majority interest in Virtus Partners ("Virtus"), previously a privately held company that provides high-value managed services and technology to the credit and loan market. The acquisition was accounted for as a business combination. FIS acquired a 70% voting and financial interest in Virtus with 30% interest retained by the founders of Virtus (the "Founders"). The agreement between FIS and the Founders provided FIS with a call option to purchase, and the Founders with a put option requiring FIS to purchase, all of the Founders' retained interest in Virtus at a redemption value determined pursuant to performance goals stated in the agreement, exercisable at any time after two years and three years, respectively, following the acquisition date. In January 2023, the Founders exercised their put option, and as a result, FIS paid the $173 million redemption value, recorded as a financing activity in the consolidated statement of cash flows, and subsequently owns 100% of Virtus.

Revenue from Contract with Customer [Abstract]
Revenue	Revenue As a result of our ongoing portfolio assessments, the Company reclassified certain non-strategic operations from Banking to Corporate and Other during the quarter ended December 31, 2023. The Company recast all prior-period segment information presented to reflect these reclassifications. Disaggregation of Revenue In the following tables, revenue is disaggregated by primary geographical market and type of revenue. The tables also include a reconciliation of the disaggregated revenue with the Company's reportable segments. For the three months ended March 31, 2024 (in millions): Capital Banking Market Corporate Solutions Solutions and Other Total Primary Geographical Markets: North America $ 1,431 $ 445 $ 41 $ 1,917 All others 253 261 36 550 Total $ 1,684 $ 706 $ 77 $ 2,467 Type of Revenue: Recurring revenue: Transaction processing and services $ 1,264 $ 371 $ 47 $ 1,682 Software maintenance 91 143 — 234 Other recurring 64 22 10 96 Total recurring 1,419 536 57 2,012 Software license 50 74 — 124 Professional services 132 96 1 229 Other non-recurring fees 83 — 19 102 Total $ 1,684 $ 706 $ 77 $ 2,467 For the three months ended March 31, 2023 (in millions): Capital Banking Market Corporate Solutions Solutions and Other Total Primary Geographical Markets: North America $ 1,420 $ 425 $ 47 $ 1,892 All others 226 238 41 505 Total $ 1,646 $ 663 $ 88 $ 2,397 Type of Revenue: Recurring revenue: Transaction processing and services $ 1,225 $ 342 $ 67 $ 1,634 Software maintenance 90 129 — 219 Other recurring 54 19 10 83 Total recurring 1,369 490 77 1,936 Software license 12 73 — 85 Professional services 154 100 2 256 Other non-recurring fees (1) 111 — 9 120 Total $ 1,646 $ 663 $ 88 $ 2,397 (1) December 31, 2023, was the final deadline for states to complete all benefit issuance under federally funded pandemic relief programs. Accordingly, revenue associated with services the Company provided related to these programs has been classified as Other non-recurring commencing in the fourth quarter of 2023, and related prior-period amounts have been reclassified from Transaction processing and services to Other non-recurring for comparability. Revenue associated with services the Company provided related to these programs was $38 million for the three months ended March 31, 2023 . Contract Balances The Company recognized revenue of $325 million and $314 million during the three months ended March 31, 2024 and 2023, respectively, that was included in the corresponding deferred revenue balance at the beginning of the periods. Transaction Price Allocated to the Remaining Performance Obligations As of March 31, 2024, approximately $22.5 billion of revenue is estimated to be recognized in the future primarily from the Banking Solutions and Capital Market Solutions segments' remaining unfulfilled performance obligations, which are primarily comprised of recurring account- and volume-based processing services. This excludes the amount of anticipated recurring renewals not yet contractually obligated. The Company expects to recognize approximately 31% of the Banking Solutions and Capital Market Solutions segments' remaining performance obligations over the next 12 months, approximately another 23% over the next 13 to 24 months, and the balance thereafter.

Amortization expense with respect to Intangible assets was $160 million and $171 million for the three months ended March 31, 2024 and 2023, respectively. Depreciation expense for property and equipment was $44 million and $42 million for the three months ended March 31, 2024 and 2023, respectively. Amortization expense with respect to software was $142 million and $152 million for the three months ended March 31, 2024 and 2023, respectively For the three months ended March 31, 2024 and 2023, Software includes $11 million and $0, respectively, of impairment primarily related to the termination of certain internally developed software projects. Goodwill Changes in goodwill during the three months ended March 31, 2024, are summarized below (in millions). Capital Corporate Banking Market And Solutions Solutions Other Total Balance, December 31, 2023 $ 12,588 $ 4,363 $ 20 $ 16,971 Goodwill attributable to acquisitions 5 25 — 30 Foreign currency adjustments (11) (16) — (27) Balance, March 31, 2024 $ 12,582 $ 4,372 $ 20 $ 16,974 We assess goodwill for impairment on an annual basis during the fourth quarter or more frequently if circumstances indicate potential impairment. We evaluated if events and circumstances as of March 31, 2024, indicated potential impairment of our reporting units. For our Banking and Capital Markets reporting units, we performed a qualitative assessment by examining factors most likely to affect our reporting units' fair values. The factors examined involve use of management judgment and included, among others, (1) forecast revenue, growth rates, operating margins, and capital expenditures used to calculate estimated future cash flows, (2) future economic and market conditions and (3) FIS' market capitalization. Based on our interim impairment assessment as of March 31, 2024, we concluded that it remained more likely than not that the fair value continues to exceed the carrying amount for each of these reporting units; therefore, goodwill was not impaired. Given the substantial excess of fair value over carrying amounts, we believe the likelihood of obtaining materially different results based on a change of assumptions to be low. Equity Security Investments The Company holds various equity securities without readily determinable fair values that primarily represent strategic investments made by the Company, as well as investments obtained through acquisitions. Such investments totaled $199 million and $195 million at March 31, 2024, and December 31, 2023, respectively, and are included within Other noncurrent assets on the consolidated balance sheets. The Company accounts for these investments at cost, less impairment, and adjusts the carrying values for observable price changes from orderly transactions for identical or similar investments of the same issuer. These adjustments are generally considered Level 2-type fair value measurements. The Company records realized and unrealized gains and losses on these investments, as well as impairment losses, as Other income (expense), net on the consolidated statements of earnings (loss) and recorded net gains (losses) of $(1) million and $(2) million for the three months ended March 31, 2024 and 2023, respectively, related to these investments.

The impact of the included fair value basis adjustments and cross-currency interest rate swaps in certain cases results in an effective weighted average interest rate being outside the stated interest rate range on the fixed rate notes. (2) Interest on the Revolving Credit Facility is generally payable at Secured Overnight Financing Rate ("SOFR") plus a margin of up to 0.428% dependent on tenor, plus an applicable margin of up to 1.625% and an unused commitment fee of up to 0.225%, each based upon the Company's corporate credit ratings. The weighted average interest rate on the Revolving Credit Facility excludes fees. (3) Other includes the amount of fair value basis adjustments due to interest rate swaps (see further discussion below in Note 10), unamortized debt issuance costs and unamortized non-cash bond discounts. Short-term borrowings as of March 31, 2024, and December 31, 2023, consisted of the following (in millions): March 31, 2024 Weighted Average Interest March 31, December 31, Rate Maturities 2024 2023 Euro-commercial paper notes ("ECP Notes") — % Up to 183 days $ — $ 2,118 U.S. commercial paper notes ("USCP Notes") — % Up to 397 days — 2,642 Total Short-term borrowings $ — $ 4,760 The Company is a party to interest rate swaps that, prior to de-designation as fair value hedges during the quarter ended September 30, 2023, converted a portion of its fixed-rate debt to variable-rate debt. As a result of the de-designations, the final fair value basis adjustments recorded through the dates of de-designation as a decrease of the long-term debt are subsequently amortized as interest expense using the effective interest method over the remaining periods to maturity of the respective long-term debt. The fair value basis adjustments reflected in Other in the long-term debt table above totaled $(259) million and $(594) million as of March 31, 2024, and December 31, 2023, respectively. The Company is also party to fixed-for-fixed cross-currency interest rate swaps under which it agrees to receive interest in foreign currency in exchange for paying interest in U.S. dollars. These are designated as fair value hedges. The Company has also entered into cross-currency interest rate swaps under which it agrees to receive interest in U.S. dollars in exchange for paying interest in a foreign currency. These are designated as net investment hedges. Although these cross-currency interest rate swaps are entered into as net investment hedges of its investments in certain of its non-U.S. subsidiaries, and not for the purpose of hedging interest rates, the benefit or cost of such hedges is reflected in interest expense in the consolidated statement of earnings (loss). As of March 31, 2024, the weighted average interest rate of the Company's outstanding debt was 3.8%, including the impact of fair value basis adjustments due to interest rate swaps and cross-currency interest rate swaps designated as fair value hedges but excluding the impact of cross-currency interest rate swaps designated as net investment hedges. Including the impact of the net investment hedge cross-currency interest rate swaps on interest expense, the weighted average interest rate of the Company's outstanding debt was 2.9%. See Note 10 for further discussion of the Company's interest rate swaps and cross-currency interest rate swaps and related hedge designations. The following table summarizes the amount of our long-term debt, including financing obligations for certain hardware and software, as of March 31, 2024, based on maturity date.

Senior Notes In March 2024, pursuant to cash tender offers, FIS purchased and redeemed an aggregate principal amount of $1.5 billion in Senior USD Notes and an aggregate principal amount of £1.0 billion in Senior GBP Notes, with interest rates ranging from 2.25% to 5.625% and maturities ranging from 2025 to 2052, resulting in a loss on extinguishment of debt of approximately $174 million, recorded in Other income (expense), net on the consolidated statement of earnings (loss), relating to tender discounts and fees; the write-off of unamortized bond discounts, debt issuance costs and fair value basis adjustments; and gains on related derivative instruments. The Company funded the purchase and redemption of the Senior Notes using a portion of the net proceeds from the Worldpay Sale. On March 1, 2024, FIS repaid an aggregate principal amount of $750 million in Senior USD Notes, on their due date, pursuant to the related indenture. On May 21, 2023, FIS repaid an aggregate principal amount of €1.3 billion in Senior Euro Notes, on their due date, pursuant to the related indenture.

As of March 31, 2024, the borrowing capacity under the Revolving Credit Facility was $4.5 billion. Fair Value of Debt The fair value of the Company's long-term debt is estimated to be approximately $994 million and $1,086 million lower than the carrying value, excluding the fair value basis adjustments due to interest rate swaps and unamortized discounts, as of March 31, 2024, and December 31, 2023, respectively.

Financial Instruments

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial Instruments	Financial Instruments Fair Value Hedges The Company held fixed-to variable interest rate swaps with aggregate notional amounts of $1,854 million, £925 million and €500 million at each of March 31, 2024, and December 31, 2023. Prior to the quarter ended September 30, 2023, these swaps were designated as fair value hedges for accounting purposes, converting the interest rate exposure on certain of the Company's Senior USD Notes, Senior GBP Notes and Senior Euro Notes, as applicable, from fixed to variable. While designated as fair value hedges, changes in fair value of these interest rate swaps were recorded as an adjustment to long-term debt. During the quarter ended September 30, 2023, the Company de-designated these swaps as fair value hedges. As a result of the de-designations, the final fair value basis adjustments recorded through the dates of de-designation as a decrease of the long-term debt are subsequently amortized as interest expense using the effective interest method over the remaining periods to maturity of the respective long-term debt. During March 2024, $316 million of unamortized fair value basis adjustments recorded as decrease of the long-term debt tendered was written-off and recorded as part of the loss on extinguishment of debt (see Note 9). At March 31, 2024, the remaining unamortized fair value basis adjustments recorded as a decrease of the long-term debt totaled $259 million, with $19 million amortized as Interest expense for the three months ending March 31, 2024 (see Note 9). At December 31, 2023, the unamortized fair value basis adjustments recorded as a decrease of the long-term debt totaled $594 million. Concurrently with the de-designations described above, the Company entered into new offsetting variable-to-fixed interest rate swaps with aggregate notional amounts of $1,854 million, £925 million and €500 million. The Company accounts for the de-designated fixed-to-variable and offsetting variable-to-fixed interest rate swaps as economic hedges; as such, effective as of the de-designation dates, changes in interest rates associated with the variable leg of the interest rate swaps do not affect the interest expense recognized, eliminating variable-rate risk on the fixed-to-variable interest rate swaps. The terms of the new interest rate swaps when matched against the terms of the existing fixed-to-variable interest rate swaps result in a net fixed coupon spread payable by the Company. The impact of the go-forward changes in fair values of the new and existing interest rate swaps, including the impact of the coupons, is recorded as Other income (expense), net pursuant to accounting for economic hedges and totaled $4 million for the three months ended March 31, 2024. The coupon payments are recorded within Other investing activities, net on the consolidated statements of cash flows and totaled $22 million cash outflows for the three months ended March 31, 2024. The new and existing interest rate swap fair values totaled assets of $13 million and $12 million and liabilities of $(649) million and $(675) million as of March 31, 2024 and December 31, 2023, respectively. During the quarter ended September 30, 2023, the Company entered into an aggregate notional amount of €3,375 million fixed-for-fixed cross-currency interest rate swaps to hedge its exposure to foreign currency risk associated with its Senior Euro Notes. During the quarter ended June 30, 2023, the Company entered into an aggregate notional amount of £925 million fixed-for-fixed cross-currency interest rate swaps to hedge its exposure to foreign currency risk associated with its Senior GBP Notes. These swaps are designated as fair value hedges for accounting purposes. During March 2024, the Company partially terminated certain fixed-for-fixed cross-currency interest rate swaps that were hedging foreign currency risk associated with its Senior GBP Notes that were partially tendered (see Note 9). After such partial termination, there remained an aggregate notional amount of approximately £170 million in fixed-for-fixed cross-currency interest rate swaps that hedge the Company's exposure to foreign currency risk associated with its Senior GBP Notes. The fair value of these swaps was a net asset of $28 million and $134 million recorded at March 31, 2024 and December 31, 2023, respectively. Changes in the swap fair values attributable to changes in spot foreign currency exchange rates are recorded in Other income (expense), net and totaled $(87) million for the three months ended March 31, 2024. This amount offset the impact of changes in spot foreign currency exchange rates on the Senior GBP Notes and Senior Euro Notes also recorded to Other income (expense), net during the hedge period. Changes in swap fair values attributable to excluded components, such as changes in fair value due to forward foreign currency exchange rates and cross-currency basis spreads, are recorded in Accumulated other comprehensive earnings (loss) ("AOCI") and totaled $68 million for the three months ended March 31, 2024. The amounts recorded in AOCI generally affect net earnings (loss) through Interest expense using the amortization approach. For the three months ended March 31, 2024, $12 million was recognized as Interest expense using the amortization approach. As a result of the partial terminations during March 2024, the Company received $33 million in net proceeds recorded within Other financing activities, net on the consolidated statement of cash flows and recorded a $19 million reduction to the loss on extinguishment of debt due to reclassifying the amount of AOCI related to the partially terminated hedges into earnings (see Note 9). Net Investment Hedges The purpose of the Company's net investment hedges, as discussed below, is to reduce the volatility of FIS' net investment value in its Euro- and Pound Sterling-denominated operations due to changes in foreign currency exchange rates. Changes in fair value due to remeasurement of the effective portion are recorded as a component of AOCI for net investment hedges. The amounts included in AOCI for the net investment hedges will remain in AOCI until the complete or substantially complete liquidation of our investment in the underlying foreign operations. Any ineffective portion of these hedging instruments impacts net earnings when the ineffectiveness occurs. The Company assesses effectiveness of cross-currency interest rate swap hedging instruments using the spot method. Under this method, the periodic interest settlements are recorded directly in earnings through Interest expense (see Note 9). The Company recorded net investment hedge aggregate gain (loss) for the change in fair value and related income tax (expense) benefit within Other comprehensive earnings (loss), net of tax, on the consolidated statements of comprehensive earnings (loss) for its designated net investment hedges as follows (in millions). No ineffectiveness has been recorded on the net investment hedges. Three months ended March 31, 2024 2023 Foreign currency-denominated debt designations $ 27 $ (117) Cross-currency interest rate swap designations 53 (104) Total $ 80 $ (221) Foreign Currency-Denominated Debt Designations The Company has designated certain foreign currency-denominated debt as net investment hedges of its investment in Euro-denominated operations. An aggregate of €1,115 million of Senior Euro Notes with maturities ranging from 2024 to 2025 was designated as a net investment hedge of the Company's investment in Euro-denominated operations as of both March 31, 2024, and December 31, 2023. An aggregate of €419 million of ECP Notes was also designated as a net investment hedge of the Company's investment in Euro-denominated operations as of December 31, 2023. The Company held €1,500 million aggregate notional amount of foreign currency forward contracts as of December 31, 2023, to economically hedge its exposure to foreign currency risk associated with ECP Notes that were previously de-designated as net investment hedges. The foreign currency forward contract fair values totaled a net asset of $41 million at December 31, 2023. Upon maturity of the forward contracts on January 31, 2024, the Company received $13 million in net proceeds recorded within Other financing activities, net on the consolidated statement of cash flows. The change in fair value of the foreign currency forward contracts is recorded as Other income (expense), net pursuant to accounting for economic hedges and offsets the impact of the change in spot foreign currency exchange rates on the de-designated ECP Notes, which is also recorded as Other income (expense), net. Cross-Currency Interest Rate Swap Designations The Company holds cross-currency interest rate swaps designated as net investment hedges of its investment in Euro- and Pound Sterling-denominated operations. As a result of the Worldpay Sale, the Company terminated its outstanding cross-currency interest rate swaps designated as net investment hedges of its investment in Pound Sterling-denominated operations on January 31, 2024.

Commitments and Contingencies	Commitments and Contingencies Securities and Shareholder Matters On March 6, 2023, a putative class action was filed in the United States District Court for the Middle District of Florida by a shareholder of the Company. The action was consolidated with another action and the consolidated case is now captioned In re Fidelity National Information Services, Inc. Securities Litigation . A lead plaintiff has been appointed, and a consolidated amended complaint was filed on August 2, 2023. The consolidated amended complaint names the Company and certain of its current and former officers as defendants and seeks damages for alleged violations of federal securities laws in connection with our disclosures relating to our former Merchant Solutions segment, including with respect to its valuation, integration, and synergies. Defendants filed a motion to dismiss the consolidated amended complaint with prejudice on September 22, 2023. We intend to vigorously defend this case, but no assurance can be given as to the ultimate outcome. On April 27, 2023, a shareholder derivative action captioned Portia McCollum, derivatively on behalf of Fidelity National Information Services, Inc. v. Gary Norcross et al., was filed in the same court by a stockholder of the Company. Plaintiff dismissed the suit without prejudice and sent a demand pursuant to Georgia Code § 14-2-742 (the "McCollum Demand"). Another stockholder, City of Hialeah Employees' Retirement System, sent a similar demand (the "Hialeah Demand"), and a third stockholder, City of Southfield Fire and Police Retirement System, also subsequently sent a similar demand (the "Southfield Demand"). The demands claim that FIS officers and directors violated federal securities laws and breached fiduciary duties, including with respect to the valuation, integration, and synergies of our former Merchant Solutions segment, and they demand that the Board investigate and commence legal proceedings against officers and directors in connection with the purported wrongdoing. On August 25, 2023, the Board established a Demand Review Committee to consider the McCollum and Hialeah Demands and any related demands that are received (such as the Southfield Demand), and make recommendations to the Board with respect to the demands. The Demand Review Committee has hired independent counsel. The Board has made no final decision with respect to the demands and has not rejected the demands. On October 18, 2023, a shareholder derivative action captioned City of Hialeah Employees' Retirement System v. Stephanie L. Ferris et al. was filed in the same court by one of the stockholders that previously had sent a demand. The complaint, which names certain of the Company's current and former officers and directors as defendants (the "Individual Defendants"), seeks to assert claims on behalf of the Company for violations of federal securities laws, breach of fiduciary duty, unjust enrichment, and contribution and indemnification, including with respect to the valuation, integration, and synergies of our former Merchant Solutions segment. On March 29, 2024, the Company and the Individual Defendants filed a motion to stay or dismiss the action without prejudice pending the completion of the Board's consideration of the demands, and the Individual Defendants concurrently filed a separate motion to dismiss. Brazilian Tax Authorities Claims In 2004, Proservvi Empreendimentos e Servicos, Ltda., the predecessor to Fidelity National Servicos de Tratamento de Documentos e Informatica Ltda. ("Servicos"), a subsidiary of Fidelity National Participacoes Ltda., our former item processing and remittance services operation in Brazil, acquired certain assets and employees and leased certain facilities from the Transpev Group ("Transpev") in Brazil. Transpev's remaining assets were later acquired by Prosegur, an unrelated third party. When Transpev discontinued its operations after the asset sale to Prosegur, it had unpaid federal taxes and social contributions owing to the Brazilian tax authorities. The Brazilian tax authorities brought a claim against Transpev and, beginning in 2012, brought claims against Prosegur and Servicos on the grounds that Prosegur and Servicos were successors in interest to Transpev. To date, the Brazilian tax authorities have filed 18 claims against Servicos, of which 16 are still active, asserting potential tax liabilities of approximately $13 million. There are potentially 20 additional claims against Transpev/Prosegur for which Servicos is named as a co-defendant or may be named but for which Servicos has not yet been served. These additional claims amount to approximately $32 million, making the total potential exposure for all 36 claims approximately $45 million. We do not believe a liability for these 36 total claims is probable and, therefore, have not recorded a liability for any of these claims. Indemnifications and Warranties The Company generally indemnifies its clients, subject to certain limitations and exceptions, against damages and costs resulting from claims of patent, copyright, or trademark infringement associated solely with its customers' use of the Company's solutions. Historically, the Company has not made any material payments under such indemnifications but continues to monitor the conditions that are subject to the indemnifications to identify whether it is probable that a loss has occurred, in which case it would recognize any such losses when they are estimable. In addition, the Company warrants to customers that its software operates substantially in accordance with the software specifications. Historically, no material costs have been incurred related to software warranties, and no accruals for warranty costs have been made.

Earnings Per Share [Abstract]
Net Earnings (Loss) per Share	Net Earnings (Loss) per Share The basic weighted average shares and common stock equivalents for the three months ended March 31, 2024 and 2023, were computed using the treasury stock method. The following table summarizes net earnings and net earnings per share attributable to FIS common stockholders for the three months ended March 31, 2024 and 2023 (in millions, except per share amounts): Three months ended March 31, 2024 2023 Net earnings (loss) from continuing operations attributable to FIS common stockholders $ 17 $ 96 Net earnings (loss) from discontinued operations attributable to FIS common stockholders 707 44 Net earnings (loss) attributable to FIS common stockholders $ 724 $ 140 Weighted average shares outstanding-basic 576 592 Plus: Common stock equivalent shares 2 1 Weighted average shares outstanding-diluted 578 593 Net earnings (loss) per share-basic from continuing operations attributable to FIS common stockholders $ 0.03 $ 0.16 Net earnings (loss) per share-basic from discontinued operations attributable to FIS common stockholders 1.23 0.07 Net earnings (loss) per share-basic attributable to FIS common stockholders $ 1.26 $ 0.24 Net earnings (loss) per share-diluted from continuing operations attributable to FIS common stockholders $ 0.03 $ 0.16 Net earnings (loss) per share-diluted from discontinued operations attributable to FIS common stockholders 1.22 0.07 Net earnings (loss) per share-diluted attributable to FIS common stockholders $ 1.25 $ 0.24 During the three months ended March 31, 2024 and 2023, options to purchase approximately 8 million and 9 million shares, respectively, of our common stock were not included in the computation of diluted earnings per share because they were anti-dilutive. In January 2021, our Board of Directors approved a share repurchase program under which it authorized the Company to repurchase up to 100 million shares of our common stock at management's discretion from time to time on the open market or in privately negotiated transactions and through Rule 10b5-1 plans. The repurchase program has no expiration date and may be suspended for periods, amended or discontinued at any time. Approximately 34 million shares remained available for repurchase as of March 31, 2024.

Segment Reporting [Abstract]
Segment Information	Segment Information As described in Note 1, effective as of the third quarter of 2023, the Company no longer reports the Merchant Solutions segment; it now reports its financial performance based on the following segments: Banking Solutions, Capital Market Solutions and Corporate and Other. Below is a summary of each segment. Banking Solutions ("Banking") The Banking segment is focused on serving financial institutions of all sizes with core processing software, transaction processing software and complementary applications and services, many of which interact directly with core processing software. We sell these solutions on either a bundled or stand-alone basis. Clients in this segment include global financial institutions, U.S. regional and community banks, credit unions and commercial lenders, as well as government institutions and other commercial organizations. We provide our clients integrated solutions characterized by multi-year processing contracts that generate recurring revenue. The predictable nature of cash flows generated from the Banking segment provides opportunities for further investments in innovation, integration, information and security, and compliance in a cost-effective manner. Capital Market Solutions ("Capital Markets") The Capital Markets segment is focused on serving global financial services clients with a broad array of buy- and sell-side solutions. Clients in this segment include asset managers, buy- and sell-side securities brokerage and trading firms, insurers, private equity firms, and other commercial organizations. Our buy- and sell-side solutions include a variety of mission-critical applications for recordkeeping, data and analytics, trading, financing and risk management. Capital Markets clients purchase our solutions in various ways including licensing and managing technology "in-house," using consulting and third-party service providers, as well as procuring fully outsourced end-to-end solutions. Our long-established relationships with many of these financial and commercial institutions generate significant recurring revenue. We have made, and continue to make, investments in modern platforms, advanced technologies, open APIs, machine learning and artificial intelligence, and regulatory technology to support our Capital Markets clients. Corporate and Other The Corporate and Other segment consists of corporate overhead expense, certain leveraged functions and miscellaneous expenses that are not included in the operating segments, as well as certain non-strategic businesses that we plan to wind down or sell. Our other operating income recorded in connection with the TSA is also recorded in Corporate and Other. The overhead and leveraged costs relate to corporate marketing, finance, accounting, human resources, legal, compliance and internal audit functions, as well as other costs, such as acquisition, integration and transformation-related expenses, and amortization of acquisition-related intangibles that are not considered when management evaluates revenue-generating segment performance. In the Corporate and Other segment, the Company recorded acquisition, integration and other costs comprised of the following (in millions): Three months ended March 31, 2024 2023 Acquisition and integration $ 24 $ 6 Enterprise transformation, including Future Forward and platform modernization 73 71 Severance and other termination expenses 18 23 Separation of the Worldpay Merchant Solutions business 30 — Incremental stock compensation directly attributable to specific programs 11 — Other, including divestiture-related expenses and enterprise cost control and other initiatives 2 — Total acquisition, integration and other costs $ 158 $ 100 Amounts in table may not sum due to rounding. Other costs in Corporate and Other also include incremental amortization expense associated with shortened estimated useful lives and accelerated amortization methods for certain software and deferred contract cost assets resulting from the Company's platform modernization, impairment charges described in Note 7 and costs that were previously incurred in support of the Worldpay Merchant Solutions business but are not directly attributable to it and thus were not recorded in discontinued operations. Adjusted EBITDA Adjusted EBITDA is a measure of segment profit or loss that is reported to the chief operating decision maker, the Company's Chief Executive Officer and President, for purposes of making decisions about allocating resources to the segments and assessing their performance. For this reason, Adjusted EBITDA, as it relates to our segments, is presented in conformity with FASB ASC Topic 280, Segment Reporting . Adjusted EBITDA is defined as net earnings (loss) before net interest expense, net other income (expense), income tax provision (benefit), equity method investment earnings (loss), and depreciation and amortization, and excludes certain costs and other transactions that management deems non-operational in nature or that otherwise improve the comparability of operating results across reporting periods by their exclusion. This measure is reported to the chief operating decision maker for purposes of making decisions about allocating resources to the segments and assessing their performance. The items affecting the segment profit measure generally include the purchase price amortization of acquired intangible assets, as well as acquisition, integration and certain other costs and asset impairments. These costs and adjustments are recorded in the Corporate and Other segment for the periods discussed below. Adjusted EBITDA for the respective segments excludes the foregoing costs and adjustments. Summarized financial information for the Company's segments is shown in the following tables. The Company does not evaluate performance or allocate resources based on segment asset data; therefore, such information is not presented.

Under this method of accounting, the Company's pro rata share of the investee's earnings or losses is reported in Equity method investment earnings (loss), net of tax, in the consolidated statement of earnings (loss). The Company also reports its investor-level tax impact relating to equity method investments as a component of Equity method investment earnings (loss) in the consolidated statement of earnings (loss). The Company monitors its investments for other-than-temporary impairment by considering factors such as current economic and market conditions and the operating performance of the investees and records reductions in carrying values when necessary.
