Segment Reporting [Abstract]
Segments and Disaggregation of Revenue	3. SEGMENTS AND DISAGGREGATION OF REVENUE The Group reports its financial statements based on four reportable segments: • U.S.; • UK & Ireland; • International; and • Australia The segment information aligns with how the chief operating decision maker (“CODM”) reviews and manages the business. The Group determined that it is the Chief Executive Officer and Chief Financial Officer jointly who are performing the function of CODM. Beginning January 1, 2024, the Group revised its definition of Adjusted EBITDA, which is the segment measurement used to evaluate performance and allocate resources. The definition of Adjusted EBITDA now excludes share-based compensation as management believes inclusion of share-based compensation can obscure underlying business trends as share-based compensation could vary widely among companies due to different plans in place resulting in companies using share-based compensation awards differently, both in type and quantity of awards granted. Effective January 1, 2024, subsequent to the Group’s decision to close the sports betting platform “FOX Bet”, the Group reorganized how the PokerStars (U.S.) business is managed which resulted in a change in operating segment composition. From January 1, 2024, PokerStars (U.S.) is included in the International segment as opposed to the U.S. segment. Segment results for the three months ended March 31, 2023, have been revised to reflect the change in operating segment measurement and change in operating segment composition. The Group manages its assets on a total company basis, not by operating segment. Therefore, the CODM does not regularly review any asset information by operating segment and accordingly, the Group does not report asset information by operating segment. The following tables present the Group’s segment information: Three months ended ($ in millions) 2024 2023 Revenue U.S. Sportsbook $ 986 $ 759 iGaming 358 241 Other 66 71 U.S. segment revenue 1,410 1,071 UKI Sportsbook 411 376 iGaming 406 319 Other 44 41 UKI segment revenue 861 736 International Sportsbook 160 181 iGaming 600 553 Other 37 26 International segment revenue 797 760 Australia Sportsbook 329 351 Australia segment revenue 329 351 Total reportable segment revenue $ 3,397 $ 2,918 iGaming revenue includes iGaming, Poker, and Lottery The information below summarizes revenue by geographical market for the three months ended March 31, 2024 and 2023: Three months ended ($ in millions) 2024 2023 U.S. $ 1,399 $ 1,083 UK 782 660 Ireland 77 78 Australia 329 351 Italy 365 369 Rest of the world 445 377 Total revenue $ 3,397 $ 2,918 The information below shows the reconciliation of reportable segment Adjusted EBITDA to loss before taxes for the three months ended March 31, 2024, and 2023: Three months ended ($ in millions) 2024 2023 U.S. $ 26 $ (53 ) UKI 268 206 International 173 149 Australia 83 85 Reportable segment adjusted EBITDA 550 387 Unallocated corporate overhead 1 (36 ) (35 ) Depreciation and amortization (297 ) (297 ) Share-based compensation expense (41 ) (46 ) Transaction fees and associated costs 2 (29 ) (3 ) Restructuring and integration costs 3 (23 ) (21 ) Other expense, net (174 ) (45 ) Interest expense, net (112 ) (92 ) Loss before taxes $ (162 ) $ (152 ) 1.

Business Combinations [Abstract]
Business Combinations	11. BUSINESS COMBINATIONS On January 10, 2024, the Group completed the acquisition of 51% of MaxBet, a leading omni-channel sports betting and iGaming operator in Serbia. The purchase comprised of a provisional cash consideration of $144 million (€132 million), which remains subject to the finalization of the completion accounts as defined in the share purchase agreement and any consequent adjustment to the provisional purchase consideration. This process is expected to be completed in the second quarter of 2024. The share purchase agreement also includes call and put options to acquire the remaining stake. The call and put options are exercisable in 2029, commencing on the date on which the option price is determined in accordance with th e non-controlling The provisional fair value of assets and liabilities acquired was $117 million. The provisional measurements of fair value for certain assets and liabilities may be subject to change as additional information is received. The Group expects to finalize the valuation as soon as practicable, but not later than one year from acquisition date. The acquisition resulted in the recognition of $116 million goodwill on the acquisition date which has been allocated to the International segment and reporting unit. The main factors leading to the recognition of goodwill (none of which is deductible for tax purposes) is the opportunity for the Group to enter the market in the Balkans region where MaxBet is one of the market leaders with an established retail and online presence. There are also tangible opportunities to deliver synergies from the acquisition of MaxBet through (i) leveraging MaxBet’s retail channel to grow online deposits for existing Flutter brands and (ii) enhancing MaxBet’s online capabilities by utilizing the Group’s technology and marketing resources. The fair value of redeemable non-controlling interest was $89 million, which was provisionally estimated by applying a discount for lack of marketability considering the output of the Finnerty method and discount for lack of control using implied discounts from observable transactions and data based on Mergerstat studies. Acquisition-related costs during the three months ended March 31, 2024 and March 31, 2023 were not material and are included in the general and administrative expenses in the Group’s consolidated statement of comprehensive (loss) / income.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	1 3 DERIVATIVES In the normal course of the Group’s business operations, it is exposed to certain risks, including changes in interest rates and foreign currency risk. In order to manage these risks, the Group uses derivative instruments such as futures, forward contracts, swaps, options and other instruments with similar characteristics. All of the Group’s derivatives are used for non-trading Cash flow hedges of interest rate and foreign currency risk Interest rate and foreign currency risk arising from a portion of the Group’s floating interest rate USD First Lien Term Loan A maturing in 2028 and USD First Lien Term Loan B maturing in 2030 respectively are managed using interest rate swaps and cross-currency interest rate swaps respectively, which are designated as cash flow hedges with the objective of reducing the volatility of interest expense and foreign currency gains and losses. Under the terms of the cross-currency interest rate swaps, the Group makes fixed- rate interest payments in pounds sterling (GBP) or euro (EUR) and receives variable interest amounts in U.S. dollars (USD) from counterparties over the life of the agreements effectively converting the variable rate term loans into fixed interest rate debts with the exchange of the underlying notional amounts at maturity whereby the Group will receive USD from and pay GBP or EUR to the counterparties at exchange rates which are determined at contract inception. Under the terms of the interest rate swaps, the Group makes fixed rate interest payments and receives variable interest amounts in USD from counterparties over the life of the agreements, effectively converting the variable rate term loans into fixed interest rate debts. The notional amount of cross-currency interest rate swaps accounted for as cash-flow hedges was $1,599 million as of March 31, 2024, and $1,603 million as of December 31, 2023 with maturities of ranging from September 2024 to June 2025. The notional amount of interest-rate swaps accounted for as cash-flow hedges was $1,092 million as of March 31, 2024 and $1,094 million as of December 31, 2023 with maturities ranging from September 2024 to June 2025. Changes in the fair value on the portion of the derivative included in the assessment of hedge effectiveness of cash-flow hedges are recorded in other comprehensive income / (loss), until earnings are affected by the variability of cash flows. Amounts recorded in accumulated other comprehensive income / (loss) were recognized in earnings within interest expense, net when the hedged interest payment was accrued. In addition, since the cross-currency interest rate swaps was a hedge of variability of the functional-currency-equivalent cash flows of the recognized term loan liability remeasured at spot exchange rates under ASC 830, “Foreign Currency Matters,” an amount that offset the gain or loss arising from the remeasurement of the hedged term loan liability was reclassified each period from accumulated other comprehensive income / (loss) to earnings in the foreign exchange loss, net, which is a component of other income, net. The amount reclassified from accumulated other comprehensive income / (loss) into , 3 The Group expects to reclassify a gain of $4 million from accumulated other comprehensive income / (loss) into Net investment hedge The Group has investments in various subsidiaries which form part of the Group’s International segment with Euro functional currencies. As a result, the Group is exposed to the risk of fluctuations between the Euro and GBP exchange rates. The Group designated its EUR First Lien Term Loan A maturing in 2028, EUR First Lien Term Loan B maturing in 2026 and receive fixed rate, pay fixed rate cross-currency interest swaps whereby the Group will receive GBP from and pay Euro to the counterparties at exchange rates which are determined at contract inception, as a net investment hedge of its Euro denominated subsidiaries which are intended to mitigate foreign currency exposure related to non-GBP As of March 31, 2024, the nominal exposures of EUR First Lien Term Loan A and EUR First Lien Term Loan B designated as net investment hedges were $959 million. The designated hedge amounts were considered highly effective. The Group has also designated certain EUR cross currency interest rate swap contracts in net investment hedging relationships. The notional amount of cross-currency swaps accounted for as net investment hedges was $350 million as of March 31, 2024. The foreign currency transaction gains and losses on the euro-denominated portion of the term loan and the cross-currency interest swaps, which are designated and effective as a hedge of the Group’s net investment in its euro-denominated functional currency subsidiaries, are included as a component of the foreign currency translation adjustment. Losses, net of tax, included in the foreign currency translation adjustment were million for the three months ended March 31, 2024, and gains, net of tax amounting to three months three months Economic hedges The Group uses cross-currency interest rate swaps to economically hedge the Group’s net foreign currency exposure arising from 1) the risk of fluctuations between the EUR and GBP exchange rates from the Group’s investment in various subsidiaries which form part of the Group’s International segment and 2) the risk of fluctuations between the USD and GBP exchange rates arising from the portion of the Group’s USD Term Loan that is not designated in a cash flow hedge. The cross-currency interest rate swaps are also used to manage the interest rate risk arising from the portion of the Group’s USD Term Loan that is not designated in a cash flow hedge. Under the terms of the cross-currency interest rate swaps, the Group makes fixed-rate interest payments in EUR and receives variable interest amounts in USD from counterparties over the life of the agreements effectively converting the variable rate debt into fixed interest rate debt with the exchange of the underlying notional amounts at maturity whereby the Group will receive USD from and pay EUR to the counterparties at exchange rates which are determined at contract inception. Changes in the fair value of these instruments are recorded in earnings throughout the term of the cross-currency interest rate swaps and are reported in other income, net in the Condensed Consolidated Statements of Comprehensive (Loss) / Income. As of March 31, 2024, the cross-currency interest rate swaps have maturities of September 2024 and June 2025.

Valuation of Level 2 financial instruments Available for sale – Player deposits – investments The Group has determined that the fair value of available for sale – player deposits – investments is determined by using observable quoted prices or observable input parameters derived from comparable bonds/markets. Although the Group has determined that a Derivative financial assets and liabilities – Swap agreements The Group uses derivative financial instruments to manage its interest rate and foreign currency risk. The valuation of these instruments is determined using widely accepted valuation techniques including discounted cash flow analysis of the expected cash flows of each derivative and incorporates credit valuation adjustments. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, such as yield curves, spot and forward FX rates. As of March 31, 2024, the Group assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions, determined that the credit valuation adjustments are not significant to the overall valuation of its derivatives. As a result, the Group determined that its valuations of its derivatives in their entirety are classified in Level 2 of the fair value hierarchy. Valuation of Level 3 financial instruments Equity securities The Group determined the fair value of investments in equity securities that do not have a readily available market value amounting to $7 million at March 31, 2024 (December 31, 2023: $9 million) using the Market Comparable Companies Approach. The EBITDA unrealized loss million) is recognized with other expense, net in the Condensed Consolidated Statements of Comprehensive (Loss) / Income. Non-derivative financial instruments Fox Option The fair value of the Fox Option amounts t million at March 31, 2024 and million at December 31, 2023 which was determined using an option pricing model. As of March 31, 2024, and December 31, 2023, the option price was $4.4 billion and $4.3 billion, respectively. The significant unobservable inputs were the enterprise value of FanDuel, the discount for lack of marketability (“DLOM”), the discount for lack of control (“DLOC”), implied volatility and probability of Fox getting licensed. The enterprise value of FanDuel was determined using an equal weight to the value indications of the discounted cash flow analysis and the guideline public company analysis. The discount rate used in the discounted cash flow analysis was 20.5% and 19.0% for the three months ended March 31, 2024 and year ended December 31, 2023, respectively. Additionally, management applied a combined discount for lack of marketability and lack of control as of March 31, 2024, and year ended December 31, 2023. A range of DLOMs obtained using these approaches was % to % . DLOC was estimated at 18.4% and 18% using implied discounts in previous observable transactions involving FanDuel’s equity ownership and data based on Mergerstat studies for the three months ended March 31, 2024, and the year ended December 31, 2023 respectively. Management selected a discount rate of 35%, which is on the higher end of the third quartile based on the ranges considered by management. The for the three months ended March 31, 2024 and year ended December 31, 2023, which was within the range of selected comparable companies. In developing the fair value measurement, the probability of a market participant submitting to and obtaining a license was estimated at % for the three months ended March 31, 2024, and the year ended December 31, 2023. Changes in discount rates, revenue multiples, DLOM, DLOC, implied volatility and probability of Fox getting licensed, each in isolation, may change the fair value of certain of the Fox Option. Generally, an increase in discount rates and DLOM, DLOC or decrease in revenue multiples, implied volatility and probability of Fox getting licensed may result in a decrease in the fair value of the Fox Option. Due to the inherent uncertainty of determining the fair value of the Fox Option, the fair value of the Fox Option may fluctuate from period to period. Additionally, the fair value of the Fox Option may differ significantly from the value that would have been used had a readily available market existed for FanDuel Group LLC. In addition, changes in the market environment and other events that may occur over the life of the Fox Option may cause the losses ultimately realized on the Fox Option to be different than the unrealized losses reflected in the valuations currently assigned. Redeemable non-controlling The terms of symmetrical call and put options agreed between the Group and Boyd require exercise price to be calculated at fair market value without giving effect to DLOM and DLOC. FanDuel’s pre-discount non-controlling Contingent c o The contingent consideration payable is primarily determined with reference to forecast performance for the acquired businesses during the relevant time periods and the amounts to be paid in such scenarios. The fair value was estimated by assigning probabilities to the potential payout scenarios. The significant unobservable inputs are forecast performance for the acquired businesses. The fair value of contingent consideration is primarily dependent on forecast performance for the acquired businesses in excess of a predetermined base target. An increase and decrease of 10% in the excess over the predetermined base target during the relevant time periods would increase and decrease the value of contingent consideration at March 31, 2024 by $2 million and $2 million, respectively (December 31, 2023: $2 million and $2 million).

The est ima Austrian and German player claims As previously reported, the Group has seen a number of player claims in Austria and Germany for reimbursement of historic gaming losses. The basis of these claims is rooted in the Group having provided remote services in Austria and Germany (outside of Schleswig-Holstein) from Maltese entities on the basis of multi-jurisdictional Maltese licenses, which the Group continues to believe is compliant in accordance with EU law. However, the Austrian Courts and certain German Courts consider the Group’s services non-compliant As of March 31, 2024, the Group expects to settle claims amounting to €13 million ($15 million) and has recognized an accrued liability within loss contingencies forming part of other current liabilities. In addition, there are further claims made against the Group amounting to €40 million ($44 million ) as of March 31, 2024, While the Group believes that it has strong arguments, at this time, the Group is unable to reasonably estimate the likelihood of the outcome due to the complexities and uncertainty around the judicial process. Others During the three months ended March 31, 2024, no additional information has become available that would cause the Group to reassess the potential liability related to the Group’s pending claims and litigations in relation to the Group’s previously reported tax dispute in PokerStars business in Italy, cybersecurity incident and G oods and cab Report.

Description of Effect on Previously Reported Segment Information for Change in Composition of Reportable Segments	Beginning January 1, 2024, the Group revised its definition of Adjusted EBITDA, which is the segment measurement used to evaluate performance and allocate resources. The definition of Adjusted EBITDA now excludes share-based compensation as management believes inclusion of share-based compensation can obscure underlying business trends as share-based compensation could vary widely among companies due to different plans in place resulting in companies using share-based compensation awards differently, both in type and quantity of awards granted. Effective January 1, 2024, subsequent to the Group’s decision to close the sports betting platform “FOX Bet”, the Group reorganized how the PokerStars (U.S.) business is managed which resulted in a change in operating segment composition. From January 1, 2024, PokerStars (U.S.) is included in the International segment as opposed to the U.S. segment. Segment results for the three months ended March 31, 2023, have been revised to reflect the change in operating segment measurement and change in operating segment composition.
