Recent Accounting Pronouncements	2. RECENT ACCOUNTING PRONOUNCEMENTS Recent Accounting Pronouncements - effective in 2024 or thereafter In October 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2023-06, Disclosure Improvements: Codification Amendments in Response to the Securities and Exchange Commission’s ("SEC") Disclosure Update and Simplification Initiative, to amend certain disclosure and presentation requirements for a variety of topics within FASB's Accounting Standards Codification ("ASC"). These amendments align the requirements in the ASC regarding the removal of certain disclosure requirements set out in Regulation S-X and Regulation S-K, announced by the SEC. The effective date for each amended topic in the ASC is either the date on which the SEC’s removal of the related disclosure requirement from Regulation S-X or Regulation S-K becomes effective, or on June 30, 2027, if the SEC has not removed the requirements by that date. Early adoption is prohibited. The Company is currently evaluating the impact of this standard on the consolidated financial statements and related disclosures. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which enhances the disclosures required for operating segments in the Company’s annual and interim consolidated financial statements. The amendments are effective for the Company in fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption of the amendment is permitted, including adoption in any interim periods for which financial statements have not been issued. The Company is currently evaluating the impact of this standard on the consolidated financial statements and related disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. ASU 2023-09 is intended to enhance the transparency and decision usefulness of income tax disclosures. The amendments address investor requests for enhanced income tax information primarily through changes to the rate reconciliation and income taxes paid information. Early adoption is permitted. The amendments are expected to be applied prospectively to all annual periods beginning after December 15, 2024. The Company is currently evaluating the impact of this standard on the consolidated financial statements and related disclosures.

We assessed goodwill for impairment by performing qualitative or quantitative analyses for each reporting unit. We concluded that the fair values of our reporting units exceeded their carrying values, and therefore no impairments were identified. Other intangible assets are comprised of the following: September 30, 2024 December 31, 2023 (in millions) Gross Carrying Amount Accumulated Amortization Net Carrying Amount Gross Carrying Amount Accumulated Amortization Net Carrying Amount Definite-lived intangible assets $ 96.0 $ (31.6) $ 64.4 $ 97.5 $ (26.4) $ 71.1 Indefinite-lived intangible assets 2,347.3 2,347.3 Total $ 2,411.7 $ 2,418.4 In the second quarter of 2023, the Company recognized a $24.5 million non-cash impairment charge for the Presque Isle Downs and Casino ("Presque Isle") gaming rights and trademark. The Company continues to monitor the current economic conditions and the impacts on the results of operations of Presque Isle. Future economic conditions could have a negative impact on the estimates and assumptions utilized in our asset impairment assessments. These potential impacts could increase the risk of a future impairment of assets at Presque Isle. We performed our annual indefinite-lived intangible assets impairment analysis as of April 1, 2024. We assessed our indefinite-lived intangible assets for impairment by performing qualitative or quantitative analyses for each asset. Based on the results of these analyses, no indefinite-lived intangible asset impairments were identified in connection with our annual impairment testing.

Income Tax Disclosure [Abstract]
Income Taxes	5. INCOME TAXES The Company’s effective income tax rate for the three months ended September 30, 2024 was higher than the U.S. federal statutory rate of 21.0% primarily resulting from state income taxes, non-deductible officer's compensation, and other non-deductible expense, partially offset by the excess tax benefit from the payment of restricted stock compensation and the tax benefit from the expiration of the statute of limitations for certain unrecognized tax benefits. The Company's effective income tax rate for the nine months ended September 30, 2024 was higher than the U.S. federal statutory rate of 21.0% primarily resulting from state income taxes and non-deductible officer's compensation.

SHAREHOLDERS' EQUITY Stock Repurchase Programs On September 29, 2021, the Board of Directors of the Company approved a common stock repurchase program of up to $500.0 million (the "2021 Stock Repurchase Program").

Share-Based Payment Arrangement [Abstract]
Stock-based Compensation Plans	7. STOCK-BASED COMPENSATION PLANS We have stock-based employee compensation plans with awards outstanding under the Churchill Downs Incorporated 2016 Omnibus Stock Incentive Plan (the "2016 Plan") and the Executive Long-Term Incentive Compensation Plan, which was adopted pursuant to the 2016 Plan. Our total stock-based compensation expense, which includes expenses related to restricted stock awards ("RSAs"), restricted stock unit awards ("RSUs"), performance share unit awards ("PSUs"), and stock options associated with our employee stock purchase plan was $7.1 million and $23.2 million for the three months and nine months ended September 30, 2024 and $8.1 million and $24.8 million for the three months and nine months ended September 30, 2023, respectively. During the nine months ended September 30, 2024, the Company awarded RSUs to employees, RSUs and PSUs to certain named executive officers ("NEOs"), and RSAs and RSUs to directors. The vesting criteria for the PSU awards granted in 2024 were based on a three-year service period with two performance conditions and a market condition related to relative total shareholder return ("TSR") consistent with prior year grants. The total compensation cost we will recognize under the PSUs is determined using the Monte Carlo valuation methodology, which factors in the value of the TSR market condition when determining the grant date fair value of the PSU. Compensation cost for each PSU is recognized during the performance and service period based on the probable achievement of the two performance criteria. The PSUs are converted into shares of our common stock at the time the PSU award value is finalized. A summary of the RSAs, RSUs and PSUs granted during 2024 is presented below (units in thousands): Grant Year Award Type Number of Units Awarded (1) Vesting Terms 2024 RSU 144 Vest equally over three 2024 PSU 63 Three 2024 RSA 4 One (1) PSUs reflect the target number of units for the original PSU grant.

On July 3, 2024, the Company closed an amendment of the Credit Agreement to (i) extend the maturity date of the Revolver and Term Loan A from 2027 to 2029 subject to an earlier “springing maturity” if certain indebtedness in respect of outstanding notes or other material indebtedness having a maturity date prior to July 3, 2029, is not refinanced or extended to a date after July 3, 2029, at least 91 days prior to such other debt’s stated maturity date, and (ii) amend certain other provisions of the Credit Agreement.

Revenue from Contract with Customer [Abstract]
Revenue from Contracts with Customers	9. REVENUE FROM CONTRACTS WITH CUSTOMERS Performance Obligations As of September 30, 2024, our Live and Historical Racing segment had remaining performance obligations on contracts with a duration greater than one year relating to television rights, sponsorships, personal seat licenses, and admissions, with an aggregate transaction price of $262.3 million. The revenue we expect to recognize on these remaining performance obligations is $1.0 million for the remainder of 2024, $58.1 million in 2025, $57.1 million in 2026, and the remainder thereafter. As of September 30, 2024, our remaining performance obligations on contracts with a duration greater than one year in segments other than Live and Historical Racing were not material. Contract Assets and Contract Liabilities As of September 30, 2024 and December 31, 2023, contract assets were not material. As of September 30, 2024 and December 31, 2023, contract liabilities were $54.9 million and $92.3 million, respectively, which are included in current deferred revenue, non-current deferred revenue, and accrued expense in the accompanying Condensed Consolidated Balance Sheets. Contract liabilities primarily relate to the Live and Historical Racing segment and the decrease was primarily due to recognized deferred revenue related to the 150th Kentucky Derby. We recognized $1.1 million and $74.1 million of revenue during the three months and nine months ended September 30, 2024, respectively, which was included in the contract liabilities balance at December 31, 2023. We recognized $1.2 million and $43.6 million of revenue during the three months and nine months ended September 30, 2023, respectively, which was included in the contract liabilities balance at December 31, 2022. Disaggregation of Revenue The Company has included its disaggregated revenue disclosures as follows: • For the Live and Historical Racing segment, revenue is disaggregated between Churchill Downs Racetrack and historical racing properties given that Churchill Downs Racetrack revenue primarily revolves around live racing events while our other Live and Historical Racing properties' revenues primarily revolve around historical racing. This segment is also disaggregated by location given the geographic economic factors that affect the revenue of service offerings. Within the Live and Historical Racing segment, revenue is further disaggregated between live and simulcast racing, historical racing, racing event-related services, and other services. • For the TwinSpires segment, revenue is disaggregated between live and simulcast racing, gaming, and other services. • For the Gaming segment, revenue is disaggregated by location given the geographic economic factors that affect the revenue of Gaming service offerings. Within the Gaming segment, revenue is further disaggregated between live and simulcast racing, racing event-related services, gaming, and other services. We believe that these disclosures depict how the amount, nature, timing, and uncertainty of cash flows are affected by economic factors.

Redeemable Noncontrolling Interest	11. REDEEMABLE NONCONTROLLING INTEREST In April 2024, the Company closed on the sale of 49% of United Tote, a wholly-owned subsidiary of CDI, to NYRA. NYRA's interest includes certain embedded redemption features, such as a put right, that are not exclusively within the Company’s control. NYRA's interest is treated as redeemable noncontrolling interest and is presented outside of permanent equity on the Company’s Condensed Consolidated Balance Sheets. The redeemable noncontrolling interest is initially accounted for at fair value and subsequently adjusted to the greater of the redemption value or the carrying value. Redeemable noncontrolling interest adjustments of carrying value to redemption value are reflected in retained earnings and are also included as an adjustment to income available to the Company’s shareholders in the calculation of earnings per share (See Note 15, Net Income Per Common Share Computations). The table below depicts changes in the Company’s redeemable noncontrolling interest balance.

INVESTMENTS IN AND ADVANCES TO UNCONSOLIDATED AFFILIATES Investments in and advances to unconsolidated affiliates as of September 30, 2024 and December 31, 2023 primarily consisted of interests in Rivers Casino Des Plaines ("Rivers Des Plaines") and Miami Valley Gaming and Racing ("MVG"). Rivers Casino Des Plaines The ownership of Rivers Des Plaines is comprised of the following: (1) the Company owns 61.3%, (2) High Plaines Gaming, LLC ("High Plaines"), an affiliate of Rush Street Gaming, LLC, owns 36.0%, and (3) Casino Investors, LLC owns 2.7%. Both the Company and High Plaines have participating rights over Rivers Des Plaines, and both must consent to certain operating, investing and financing decisions. As a result, we account for Rivers Des Plaines using the equity method. As of September 30, 2024 , the net aggregate basis difference between the Company’s investment in Rivers Des Plaines and the amounts of the underlying equity in net assets was $832.9 million. Our investment in Rivers Des Plaines was $537.9 million and $541.2 million as of September 30, 2024 and December 31, 2023, respectively. The Company received distributions from Rivers Des Plaines of $78.8 million and $93.1 million for the nine months ended September 30, 2024 and 2023, respectively. Miami Valley Gaming and Racing The Company owns a 50% interest in MVG and Delaware North Companies Gaming & Entertainment Inc. ("DNC") owns the remaining 50% interest in MVG. Since both the Company and DNC have participating rights over MVG, and both must consent to certain operating, investing and financing decisions, we account for MVG using the equity method. Our investment in MVG was $112.3 million and $114.6 million as of September 30, 2024 and December 31, 2023, respectively. The Company received distributions from MVG of $35.0 million and $33.5 million for the nine months ended September 30, 2024 and 2023, respectively.

Fair Value Disclosures [Abstract]
Fair Value of Assets And Liabilities	13. FAIR VALUE OF ASSETS AND LIABILITIES We endeavor to utilize the best available information in measuring fair value. Financial assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurement. The following methods and assumptions are used to estimate the fair value of each class of financial instruments for which it is practicable to estimate. Restricted Cash Our restricted cash accounts held in money market and interest-bearing accounts qualify for Level 1 in the fair value hierarchy, which includes unadjusted quoted market prices in active markets for identical assets. Debt The fair value of the Company’s 2031 Senior Notes, 2030 Senior Notes, 2028 Senior Notes, and 2027 Senior Notes are estimated based on unadjusted quoted prices for identical or similar liabilities in markets that are not active and as such are Level 2 measurements. The fair values of the Company's Term Loan B-1, Term Loan A, and Revolver under the Credit Agreement approximate the gross carrying value of the variable rate debt and as such are Level 2 measurements. The carrying amounts and estimated fair values by input level of the Company's financial instruments are as follows: September 30, 2024 (in millions) Carrying Amount Fair Value Level 1 Level 2 Level 3 Financial assets: Restricted cash $ 78.7 $ 78.7 $ 78.7 $ — $ — Financial liabilities: Term Loan B-1 287.4 289.5 — 289.5 — Term Loan A 1,181.4 1,187.4 — 1,187.4 — Revolver 290.0 290.0 — 290.0 — 2027 Senior Notes 597.3 595.7 — 595.7 — 2028 Senior Notes 698.9 684.7 — 684.7 — 2030 Senior Notes 1,187.3 1,195.2 — 1,195.2 — 2031 Senior Notes 591.4 619.5 619.5 December 31, 2023 (in millions) Carrying Amount Fair Value Level 1 Level 2 Level 3 Financial assets: Restricted cash $ 77.3 $ 77.3 $ 77.3 $ — $ — Financial liabilities: Term Loan B-1 289.2 291.8 — 291.8 — Term Loan A 1,228.7 1,235.0 — 1,235.0 — Revolver 247.2 247.2 — 247.2 — 2027 Senior Notes 596.5 591.8 — 591.8 — 2028 Senior Notes 698.7 668.6 — 668.6 — 2030 Senior Notes 1,185.6 1,171.5 — 1,171.5 — 2031 Senior Notes 590.4 611.2 — 611.2 —

Commitments and Contingencies Disclosure [Abstract]
Contingencies	14. CONTINGENCIES We are involved in litigation arising in the ordinary course of conducting business. We carry insurance for workers' compensation claims from our employees and general liability for claims from independent contractors, customers, and guests. We are self-insured up to an aggregate stop loss for our general liability and workers' compensation coverages. We review all litigation on an ongoing basis when making accrual and disclosure decisions. For certain legal proceedings, we cannot reasonably estimate losses or a range of loss, if any, particularly for proceedings that are in the early stages of development or where the plaintiffs seek indeterminate damages. Various factors, including but not limited to, the outcome of potentially lengthy discovery and the resolution of important factual questions, may need to be determined before probability can be established or before a loss or range of loss can be reasonably estimated. In accordance with current accounting standards for loss contingencies and based upon information currently known to us, we establish reserves for litigation when it is probable that a loss associated with a claim or proceeding has been incurred and the amount of the loss or range of loss can be reasonably estimated. When no amount within the range of loss is a better estimate than any other amount, we accrue the minimum amount of the estimable loss. To the extent that such litigation against us may have an exposure to a loss in excess of the amount we have accrued, we believe that such excess would not be material to our consolidated financial condition, results of operations, or cash flows. Legal fees are expensed as incurred. If the loss contingency in question is not both probable and reasonably estimable, we do not establish an accrual and the matter will continue to be monitored for any developments that would make the loss contingency both probable and reasonably estimable. In the event that a legal proceeding results in a substantial judgment against us, or settlement by us, there can be no assurance that any resulting liability or financial commitment would not have a material adverse impact on our business.

Segment Reporting [Abstract]
Segment Information	16. SEGMENT INFORMATION We manage our operations through three reportable segments: Live and Historical Racing, TwinSpires, and Gaming. Our operating segments reflect the internal management reporting used by our chief operating decision maker to evaluate results of operations and to assess performance and allocate resources. On September 7, 2023, the Company began operating retail sports betting at its racetracks and HRM facilities in Kentucky. In addition to retail sports betting, third-party service providers began operating online sports wagering in partnership with the Company’s racetracks on September 28, 2023. Our retail and online sports betting business is included in the TwinSpires segment. Eliminations include the elimination of intersegment transactions. We utilize non-GAAP measures, including EBITDA (earnings before interest, taxes, depreciation and amortization) and Adjusted EBITDA. Our chief operating decision maker utilizes Adjusted EBITDA to evaluate segment performance, develop strategy, and allocate resources. Adjusted EBITDA includes the following adjustments: Adjusted EBITDA includes our portion of EBITDA from our equity investments and the portion of EBITDA attributable to a noncontrolling interest. Adjusted EBITDA excludes: • Transaction expense, net which includes: – Acquisition, disposition, and property sale related charges; – Other transaction expense, including legal, accounting, and other deal-related expense; • Stock-based compensation expense; • Asset impairments; • Gain on property sales; • Legal reserves; • Pre-opening expense; and • Other charges, recoveries, and expenses As of December 31, 2021, our property in Arlington Heights, Illinois ("Arlington") ceased racing and simulcast operations and the property was sold on February 15, 2023 to the Chicago Bears. Arlington's results and exit costs in 2023 are treated as an adjustment to EBITDA . On June 26, 2023, the Company's management agreement for Lady Luck Casino Nemacolin ("Lady Luck") in Farmington, Pennsylvania expired and was not renewed. The Company completed the sale of substantially all its assets at Lady Luck for an immaterial amount. We utilize the Adjusted EBITDA metric to provide a more accurate measure of our core operating results and enable management and investors to evaluate and compare from period to period our operating performance in a meaningful and consistent manner. Adjusted EBITDA should not be considered as an alternative to operating income as an indicator of performance, as an alternative to cash flows from operating activities as a measure of liquidity, or as an alternative to any other measure provided in accordance with GAAP. Our calculation of Adjusted EBITDA may be different from the calculation used by other companies and, therefore, comparability may be limited. For segment reporting, Adjusted EBITDA includes intercompany revenue and expense totals that are eliminated in the accompanying Condensed Consolidated Statements of Comprehensive Income.

Accounting Policies [Abstract]
Recent Accounting Pronouncements - Effective in 2024 or Thereafter	Recent Accounting Pronouncements - effective in 2024 or thereafter In October 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2023-06, Disclosure Improvements: Codification Amendments in Response to the Securities and Exchange Commission’s ("SEC") Disclosure Update and Simplification Initiative, to amend certain disclosure and presentation requirements for a variety of topics within FASB's Accounting Standards Codification ("ASC"). These amendments align the requirements in the ASC regarding the removal of certain disclosure requirements set out in Regulation S-X and Regulation S-K, announced by the SEC. The effective date for each amended topic in the ASC is either the date on which the SEC’s removal of the related disclosure requirement from Regulation S-X or Regulation S-K becomes effective, or on June 30, 2027, if the SEC has not removed the requirements by that date. Early adoption is prohibited. The Company is currently evaluating the impact of this standard on the consolidated financial statements and related disclosures. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which enhances the disclosures required for operating segments in the Company’s annual and interim consolidated financial statements. The amendments are effective for the Company in fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption of the amendment is permitted, including adoption in any interim periods for which financial statements have not been issued. The Company is currently evaluating the impact of this standard on the consolidated financial statements and related disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. ASU 2023-09 is intended to enhance the transparency and decision usefulness of income tax disclosures. The amendments address investor requests for enhanced income tax information primarily through changes to the rate reconciliation and income taxes paid information. Early adoption is permitted. The amendments are expected to be applied prospectively to all annual periods beginning after December 15, 2024. The Company is currently evaluating the impact of this standard on the consolidated financial statements and related disclosures.
