The accompanying consolidated financial statements are presented in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”). The consolidated financial statements include the accounts and operations of the Company and its subsidiaries. All intercompany accounts and transactions are eliminated upon consolidation. Certain amounts, which are not material, in the prior years’ consolidated financial statements have been reclassified to conform to the current year presentation.

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates and assumptions reflected in the financial statements relate to and include, but are not limited to, the valuation and expensing of equity awards, accounting for contingencies and uncertainties, purchase price allocations, including fair value estimates of intangible assets and contingent consideration, the estimated useful lives of fixed assets and intangible assets, internally developed software costs, including judgments related to capitalization eligibility, capitalization periods and useful lives, accrued expenses and income tax related estimates and judgments, including the realizability of deferred tax assets, valuation allowances and uncertain tax positions.

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, restricted cash, cash reserved for users, loans receivable and surety bonds. The Company maintains separate accounts for cash and cash reserved for users primarily across several financial institutions. Some of the amounts held exceed federally insured limits. Management believes all financial institutions holding its cash are of high credit quality and does not believe the Company is subject to unusual credit risk beyond the normal credit risk associated with commercial banking relationships.

The Company accounts for business combinations under the acquisition method of accounting, in accordance with Accounting Standards Codification (“ASC”) Topic 805, Business Combinations (“ASC 805”), which requires assets acquired and liabilities assumed to be recognized at their fair values as of the acquisition date. Any fair value of purchase consideration in excess of the fair value of the assets acquired less liabilities assumed is recorded as goodwill. The fair values of the assets acquired and liabilities assumed are determined based upon the valuation of the acquired business and involve management making significant estimates and assumptions.

We maintain cash in bank accounts at financial institutions that exceed federally insured limits. We also maintain cash in money market funds which are not insured by the Federal Deposit Insurance Corporation (FDIC). We are subject to credit risk to the extent any financial institution with which we conduct business is unable to fulfill contractual obligations on our behalf. As we have not experienced any material losses in such accounts and we believe that we have placed our cash on deposit with financial institutions which are financially stable, we do not have an expectation of credit losses for these arrangements.

Cash reserved for users represents cash deposited by players in order to engage in our revenue-generating offerings and is maintained in separate bank accounts to segregate users’ funds from operational funds. In certain regulated jurisdictions, user funds are held by DK Player Reserve LLC, a Delaware limited liability company and wholly owned subsidiary of DraftKings Inc., which was organized for the purpose of protecting users’ funds in the event of creditor claims and complying with certain regulatory requirements of gaming authorities in certain jurisdictions.

Accounts receivable is recorded at amortized cost, less any allowance for credit losses. The allowance for credit losses is determined based on the Company’s assessment of the probability of non-payment of the receivable after all means of collection have been exhausted and the potential for recovery is considered remote. Accounts receivable are written off against the allowance for credit losses when collection efforts have been exhausted and recovery is deemed remote. This provision is netted against the receivable balance with the loss being recognized within general and administrative expenses in the consolidated statements of operations. As of and for the years ending December 31, 2025 and 2024, the provision did not have a material impact on the Company’s consolidated financial statements.

The Company’s intangible assets primarily consist of developed technology, customer relationships, internally-developed software, gaming market access and licenses, and trademarks and tradenames. The related amortization expense is classified as cost of revenue in the consolidated statements of operations. Estimates and assumptions that we must make in estimating the fair value of future acquired technology, user lists and other identifiable intangible assets include future cash flows that we expect to generate from the acquired assets.

Software that is developed for internal use is accounted for pursuant to ASC Topic 350-40, Intangibles, Goodwill and Other—Internal-Use Software (“ASC 350-40”). Qualifying costs incurred to develop internal-use software are capitalized when (i) the preliminary project stage is completed, (ii) management has authorized further funding for the completion of the project and (iii) it is probable that the project will be completed and perform as intended. These capitalized costs include compensation for employees who develop internal-use software and external costs related to development of internal use software. Capitalization of these costs ceases once the project is substantially complete and the software is ready for its intended purpose. Internally developed software is amortized using the straight-line method over an estimated useful life. All other expenditures, including those incurred in order to maintain an intangible asset’s current level of performance, are expensed as incurred. When intangible assets are retired or disposed of, the cost and accumulated amortization thereon are removed, and any resulting gains or losses are included in the consolidated statements of operations.

The Company incurs fees in connection with applying for and maintaining good standing in jurisdictions via business licenses. Fees incurred in connection with the application and subsequent renewals are capitalized and amortized using the straight-line method over an estimated useful life. In certain arrangements, the Company enters into agreements to operate on a business partner’s license in exchange for upfront fees. These fees are capitalized and amortized over the shorter of their expected benefit under the partnership agreement or estimated useful life.

Long-lived assets, except for goodwill and indefinite-lived intangible assets, consist of property and equipment and finite-lived acquired intangible assets, such as internal-use software, developed software, gaming licenses, trademarks, tradenames and customer relationships. Long-lived assets, except for goodwill and indefinite-lived assets, are tested for recoverability whenever events or changes in business circumstances indicate that the carrying amount of the asset may not be fully recoverable. Impairment expense is recognized to the extent an asset’s expected undiscounted future cash flows are less than the asset’s carrying amount. The Company determined that there was no impairment of long-lived assets during 2025, 2024 or 2023.

The Company performs its evaluation for the impairment of goodwill associated with the Company’s reporting units on an annual basis as of each October 1, or more frequently if an event occurs or circumstances change that would indicate that a reporting unit’s carrying amount may be impaired. The Company reviews its reporting unit structure each year, or more frequently based on changes in our organization. Prior to the fourth quarter of 2025, the Company operated as a single reporting unit for purposes of goodwill allocation and impairment assessment. Upon the acquisition of Railbird and launch of our prediction markets product offering, the Company has now concluded that it has two reporting units, with prediction markets being a standalone reporting unit. In 2025, the annual goodwill impairment assessment was performed on the Company’s two reporting units. In 2024 and 2023, the annual goodwill impairment assessment was performed on the Company’s one consolidated reporting unit. In the fourth quarter of 2025, 2024 and 2023, as part of its annual evaluations, the Company utilized the option to first assess qualitative factors to determine whether it was necessary to perform the quantitative goodwill impairment assessment. As part of these assessments, the Company reviews qualitative factors, which include, but are not limited to, reviewing factors such as macroeconomic conditions, industry and market considerations, cost factors, entity-specific financial performance and other events, such as changes in the Company’s management, strategy and primary user base. In accordance with applicable guidance, an entity is not required to calculate the fair value of a reporting unit if, after assessing these qualitative factors, the Company determines that it is more likely than not that the fair value of each of its reporting units is greater than its respective carrying amount. As of October 1, 2025, 2024 and 2023, the Company determined that it was more likely than not that the fair value of each of its reporting units exceeded its respective carrying amount and, therefore, a quantitative assessment was not required. As a result, no goodwill impairment resulted from the assessments as of October 1, 2025, 2024 and 2023. As of December 31, 2025, the Company had no accumulated goodwill impairment losses.

Contingent consideration in a business combination is included as part of the acquisition cost and is recognized at fair value as of the acquisition date. For contingent consideration, management is responsible for determining the appropriate valuation model and estimated fair value, and in doing so, considers a number of factors, including information provided by an outside valuation advisor. Contingent consideration liabilities are reported at their estimated fair values based on probability-adjusted present values of the consideration expected to be paid, using significant inputs and estimates. Key inputs to the valuations are the projections of future financial results in relation to the business, including market based assumptions, revenue volatility, equity volatility and operational leverage ratio as well as management judgment regarding the probability of achieving a future performance target. The fair value of contingent consideration liabilities is remeasured each reporting period, with changes in the fair value included in current operations. The remeasured liability amount could be significantly different from the amount at the acquisition date, resulting in material charges or credits in subsequent reporting periods.

The Company has equity method investments, including in DKFS, LLC, DBDK Venture Fund I, L.P., DBDK Venture Fund II, L.P. The Company uses the equity method to account for investments in which the Company has the ability to exercise significant influence over the operating and financial policies of the investee, but the Company does not exercise control and is not the primary beneficiary. The Company’s judgment regarding its level of influence over the equity method investee includes considering key factors, such as ownership interest, representation on the board of directors and participation in policy-making

Under the equity method, the Company’s investment is initially measured at cost and subsequently increased or decreased to recognize the Company’s share of income and losses of the investee, capital contributions and distributions and impairment losses. The Company performs a qualitative assessment annually and recognizes an impairment if there are sufficient indicators that the fair value of the investment is less than carrying value. There was no such impairment recorded during 2025, 2024 or 2023.

The Company determines if an arrangement is a lease at inception and categorizes it as either operating or finance based on the criteria of ASC Topic 842, Leases. An arrangement contains a lease when the arrangement conveys the right to control the use of an identified asset over the lease term. Operating leases are recorded in the consolidated balance sheets. The Company currently does not have any finance leases. The Company elects certain practical expedients that include not separating lease and non-lease components and it does not apply the right-of-use (“ROU”) assets and lease liability recognition requirements to short-term leases.

Lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at the commencement date. These leases typically do not provide an implicit rate; therefore, the Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of future lease payments. The incremental borrowing rate is the rate incurred to borrow on a collateralized basis over a similar term in an amount equal to the lease payments in a similar economic environment. ROUs are recognized at the lease commencement date at the value of the lease liability, adjusted for any lease payments made prior to commencement and exclude lease incentives and initial direct costs incurred. The lease terms include all non-cancelable periods and may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense is recognized on a straight-line basis over the expected lease term.

The Company’s loss contingencies, which are included within accounts payable and accrued expenses or other long-term liabilities in our consolidated balance sheets, are uncertain by nature and their estimation requires significant management judgment as to the probability of loss and estimation of the amount of such loss. These contingencies include, but may not be limited to, litigation, indirect taxes, regulatory investigations and proceedings and management’s evaluation of complex laws and regulations, and the extent to which they may apply to our business and industry.

The Company regularly reviews its contingencies to determine whether the likelihood of loss is probable or reasonably possible and to assess whether a reasonable estimate of the loss can be made. Determination of whether a loss estimate can be made is a complex undertaking that considers the judgement of management, third-party research, the prospect of negotiation and interpretations by regulators and courts, among other information. When a loss is determined to be probable, and the amount of the loss can be reasonably estimated, an estimated contingent liability is recorded and the related legal costs are expensed as incurred.

The Company is currently engaged in the business of digital sports entertainment and gaming and provides its users with online gaming opportunities. The Company also provides online sportsbook and casino operators with technical infrastructure as well as related services with respect to its direct customers and distributors. The Company has also entered prediction markets in which the Company acts as an introducing broker, and therefore revenue is generated from introducing fees paid by futures commission merchants. The following is a description of the Company’s revenue streams:

Sportsbook or sports betting involves a user wagering money on an outcome or series of outcomes occurring. When a user’s wager wins, the Company pays the user a pre-determined amount known as fixed odds. Sportsbook revenue is generated by setting odds such that there is a built-in theoretical margin in each sports wagering opportunity offered to users. Sportsbook revenue is generated from users’ wagers net of payouts made on users’ winning wagers and incentives awarded to users.

Sportsbook, iGaming, and DFS create a single performance obligation for the Company to operate contests or games and award prizes or payouts to users based on results. Revenue is recognized at the conclusion of each wager, wagering game hand or contest. Incentives can be used across online gaming product offerings. Additionally, certain incentives given to customers create material rights and represent separate performance obligations. User incentives in certain cases create liabilities when awarded to players and in those cases are generally recognized as revenue upon redemption.

Prediction markets allows customers to trade event-based contracts listed on regulated exchanges. During the reporting period, the Company acted solely as an introducing broker, earning fees for onboarding traders and routing orders to a futures commission merchant for execution. Revenue is generated from introducing fees, paid by futures commission merchants, and is recognized when customer trades occur. The Company does not execute trades, hold customer funds, or assume risk related to event-based contract outcomes.

Variability in the transaction price arises primarily due to market-based pricing, cash discounts, revenue sharing and usage-based fees. DraftKings offers loyalty programs, free plays, deposit bonuses, discounts, rebates and other rewards and incentives to its customers. Revenue for Sportsbook, iGaming, DFS and digital lottery courier is collected prior to the contest or event and is fixed once the outcome is known. Prizes paid and payouts made to users are recognized when awarded to the player.

Contracts with customers may include multiple performance obligations. For such arrangements, the transaction price is allocated to performance obligations on a relative standalone selling price basis. Standalone selling prices are estimated based on observable data of the Company’s sales of such products and services to similar customers and in similar circumstances on a standalone basis. For Sportsbook, iGaming, DFS and digital lottery courier, the Company allocates a portion of the transaction price to certain customer incentives that create material future customer rights. In addition, in the event of a multi-stage contest, the Company will allocate transaction price ratably from contest start to the contest’s final stage. For prediction markets, the Company identifies a single performance obligation to introduce traders to futures commission merchants for the execution of trades, and accordingly the transaction price is not further allocated.

Under ASC 606, certain costs to obtain or fulfill a contract with a customer must be capitalized, to the extent recoverable from the associated contract margin, and subsequently amortized as the products or services are delivered to the customer. These costs are capitalized as contract acquisition costs and are amortized over the period of benefit to the customer. For the Company, the period of benefit is typically less than or equal to one year. As such, the Company applied the practical expedient and contract acquisition costs are expensed immediately. Customer contract costs which do not qualify for capitalization as contract fulfillment costs are expensed as incurred.

Deferred revenue primarily represents contract liabilities related to the Company’s obligation to transfer future value in relation to in-period transactions in which the Company has received consideration. Such obligations are recognized as liabilities when awarded to users and are recognized as revenue when those liabilities are later resolved. The Company maintains various programs to incentivize user behavior, which allow users to earn awards. Incentive awards generally represent a material right to the user, and awards may be redeemed for future services. Incentive awards earned by users, but not yet redeemed, are generally recognized as a reduction to revenue and included within liabilities to users on our consolidated balance sheets. When a user redeems most types of awards, the Company recognizes revenue on its consolidated statements of operations. Certain player awards are not subject to expiration or have not been expired historically; on such awards the Company recognizes breakage (for amounts not expected to be redeemed) to the extent there is no requirement for remitting such balances to regulatory agencies. In addition to these incentive programs, the Company’s deferred revenue balance also consists of wagered amounts that relate to unsettled or pending outcomes.

Cost of revenue consists primarily of variable costs. These include mainly (i) product taxes; (ii) payment processing fees and chargebacks; (iii) platform costs directly associated with revenue-generating activities, including those costs that were originally capitalized for internally developed software; (iv) revenue share / market access arrangements and (v) feed / provider services. The Company incurs payment processing fees on user deposits, withdrawals and deposit reversals from payment processors. Cost of revenue also includes expenses related to the distribution of our services, amortization of intangible assets and compensation of revenue associated personnel.

Sales and marketing expenses consist primarily of expenses associated with advertising, conferences, costs related to free to play contests, rent and facilities maintenance and the compensation of sales and marketing personnel, including stock-based compensation expenses. Advertising costs are expensed as incurred and are included in sales and marketing expense in our consolidated statements of operations. Advertising costs include those costs associated with communicating with potential customers and generally use some form of media, such as internet, radio, print, television or billboards. Advertising costs also include costs associated with strategic league and team partnerships. During the years ended December 31, 2025, 2024 and 2023, advertising costs calculated in accordance with U.S. GAAP were $1,124.8 million, $1,049.6 million and $984.4 million, respectively.

Product and technology expenses consist primarily of research and development costs that are not capitalized and other costs not associated directly with revenue generating activities. Research and development costs primarily represent employee expenses (including stock-based compensation) for engineering product, design, analytical research and project management incurred for non-revenue generating activities. Other costs include related overhead for rent, facilities maintenance, third-party software licenses and consulting services.

General and administrative expenses consist of costs not related to sales and marketing, product and technology or revenue. General and administrative costs include professional services (including legal, regulatory, audit, accounting, lobbying and services related to acquisitions), rent and facilities maintenance, contingencies, insurance, allowance for credit losses, depreciation of leasehold improvements and furniture and fixtures and costs related to the compensation of executive and non-executive personnel, including stock-based compensation.

The Company measures compensation cost for stock options and other stock awards in accordance with ASC Topic 718, Compensation—Stock Compensation. Stock-based compensation is measured at fair value on grant date and recognized as compensation cost over the requisite service period. Generally, the Company issues stock options and other stock awards to employees with service-based or performance-based vesting conditions. For awards with only service-based vesting conditions, the Company records compensation cost for these awards using the straight-line method less an assumed forfeiture rate. For awards with performance-based vesting conditions, the Company recognizes compensation cost on a tranche-by-tranche basis (the accelerated attribution method), based on the probability of achieving the performance criteria.

The Company accounts for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the consolidated financial statements or in the Company’s tax returns. Deferred tax assets and liabilities are determined on the basis of the differences between U.S. GAAP treatment and tax treatment of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Deferred tax liabilities are included in other long-term liabilities in the consolidated balance sheets. Changes in deferred tax assets and liabilities are included in the income tax (benefit) provision in the consolidated statement of operations. The Company assesses the likelihood that its deferred tax assets will be recovered from future taxable income and, to the extent it believes, based upon the weight of available evidence, that it is more likely than not that all or a portion of the deferred tax assets will not be realized, a valuation allowance is established through a charge to income tax expense. Potential for recovery of deferred tax assets is evaluated by considering taxable income of the appropriate source and character in carryback years, existing taxable temporary differences, prudent and feasible tax planning strategies and estimated future taxable profits.

The Company accounts for uncertainty in income taxes recognized in its consolidated financial statements by applying a two-step process to determine the amount of tax benefit to be recognized. First, the tax position must be evaluated to determine the likelihood that it will be sustained upon external examination by the taxing authorities. If the tax position is deemed more-likely-than-not to be sustained, the tax position is then measured to determine the amount of benefit to recognize in our consolidated financial statements. Liabilities for uncertain tax positions are included in long-term income tax liabilities in the consolidated balance sheets. The amount of the benefit that may be recognized is the largest amount that has a greater than 50% likelihood of being realized upon ultimate settlement. The income tax (benefit) provision includes the effects of any resulting tax reserves, or unrecognized tax benefits, that are considered appropriate, as well as the related net interest and penalties.

Basic loss per share is calculated using the two-class method. Under the two-class method, basic loss per share is computed by dividing net loss available to common stockholders by the weighted-average number of common shares outstanding during the period excluding the effects of any potentially dilutive instruments. The weighted-average number of common shares outstanding during the period includes Class A common stock but is exclusive of Class B common stock as these shares have no economic or participating rights. Diluted loss per share is computed similar to basic loss per share, except that the denominator is increased to include the number of additional common shares that would have been outstanding if potential common shares had been issued if such additional common shares were dilutive. For certain contracts that may be settled in shares and are accounted for as assets or liabilities, the numerator is also adjusted for changes in income or loss that would have resulted if such contracts had been classified as equity, when dilutive. For periods presented with net losses, basic and diluted loss per share are the same, and additional potential common shares have been excluded, as their effect would be anti-dilutive.

In December 2023, the FASB issued ASU 2023-09, Income Taxes—Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”). ASU 2023-09 modifies the rules on income tax disclosures to enhance the transparency and decision-usefulness of income tax disclosures, particularly in the rate reconciliation table and disclosures about income taxes paid. The guidance also eliminates certain existing disclosure requirements related to uncertain tax positions and unrecognized deferred tax liabilities. The Company adopted ASU 2023-09 prospectively for the year ending December 31, 2025. Refer to “Note 12 — Income Taxes” in the consolidated financial statements.

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 (“ASU 2024-03”), which requires disaggregated disclosure of income statement expenses. ASU 2024-03 does not change the expense captions an entity presents on the face of the income statement; rather, it requires disaggregation of certain expense captions into specified categories in disclosures within the footnotes to the financial statements. ASU 2024-03 is effective for public business entities for annual periods beginning after December 15, 2026, with early adoption permitted. We are currently evaluating the impact of this standard on our disclosure of income statement expenses.

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 (“ASU 2025-06”). ASU 2025-06 changes the accounting for internal-use software under ASC 350-40. ASU 2025-06 clarifies when to begin capitalizing costs. ASU 2025-06 is effective for interim and annual periods beginning after December 15, 2027, with early adoption permitted. We are currently evaluating the impact of this standard on our consolidated financial statements.

In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements (“ASU 2025-11”). ASU 2025-11 clarifies the applicability of interim reporting guidance and reorganizes and clarifies interim disclosure requirements under ASC Topic 270, including the addition of a disclosure principle requiring disclosure of material events occurring since the most recent annual reporting period. ASU 2025-11 is effective for interim reporting periods within annual periods beginning after December 15, 2027, with early adoption permitted. We are currently evaluating the impact of this standard on our consolidated financial statements.

In December 2025, the FASB issued ASU 2025-12, Codification Improvements (“ASU 2025-12”). ASU 2025-12 makes targeted amendments to various topics within the Accounting Standards Codification intended to clarify existing guidance and correct minor inconsistencies. ASU 2025-12 is effective for interim and annual reporting periods beginning after December 15, 2026, with early adoption permitted. Certain amendments require retrospective application. We are currently evaluating the impact of this standard on our consolidated financial statements.
