We have audited the accompanying consolidated balance sheets of Boyd Gaming Corporation and subsidiaries (the "Company") as of December 31, 2025 and 2024, the related consolidated statements of operations, comprehensive income, changes in stockholders' equity, and cash flows, for each of the three years in the period ended December 31, 2025, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) ("PCAOB"), the Company's internal control over financial reporting as of December 31, 2025, based on criteria established inInternal Control—* Integrated Framework (2013)* issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 20, 2026, expressed an unqualified opinion on the Company's internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Goodwill and Gaming License Rights Indefinite-Lived Intangible Assets***—***Refer to Notes 1, 4 and 5 to the financial statements

Critical Audit Matter Description

The Company’s evaluation of goodwill for impairment involves the comparison of the fair value of a reporting unit to its carrying value. Similarly, the Company’s evaluation of its gaming license rights indefinite-lived intangible assets for impairment involves the comparison of the fair value of each gaming license right indefinite-lived intangible asset to its carrying value. As of December 31, 2025, the carrying value of goodwill and gaming license rights indefinite-lived intangible assets was $958.0 million and $1,203.9 million, respectively. Management estimated the fair value of reporting units using a weighting of the income approach and the market approach and estimated the fair value of gaming license rights indefinite-lived intangible assets using a multi-period excess earnings method.

The determination of the fair value of reporting units required management to make significant assumptions and estimates including, projections of future cash flows and the selection of discount rates and valuation multiples derived from the operating data of selected guideline publicly-traded companies. The determination of the fair value of gaming license rights indefinite-lived intangible assets required management to make significant assumptions and estimates including, projections of future cash flows and the selection of discount rates.

Therefore, auditing these fair values involved a higher degree of judgment and subjectivity, including the involvement of valuation specialists.

How the Critical Audit Matter Was Addressed in the Audit
