REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the Board of Directors of Bally’s Corporation

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Bally's Corporation and subsidiaries (the "Company") as of December 31, 2024 and 2023, the related consolidated statements of operations, comprehensive income (loss), stockholders' equity, and cash flows, for each of the three years in the period ended December 31, 2024, 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, 2024 and 2023, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2024, 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, 2024, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated March 17, 2025, expressed an adverse opinion on the Company's internal control over financial reporting because of a material weakness.

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 – International Interactive Reporting Unit – Refer to Notes 2 and 11 to the financial statements.

Critical Audit Matter Description

The Company’s goodwill is tested annually for impairment, or more frequently if indicators of impairment exist, by comparing the fair value of the respective reporting units to their carrying value. The Company determines the fair value of its reporting units in consideration of the income-based and market-based approaches. The key inputs in determining the fair value of the International Interactive reporting unit include expected cash flows and projected financial results, including forecasted revenues (collectively the “International Interactive forecasts”), the selection of the discount rate, and market multiples. As of December 31, 2024, the value of the International Interactive reporting unit goodwill is $1,451.3 million.

The Company’s fair value determination of its International Interactive reporting unit required management to make significant estimates and assumptions of International Interactive forecasts, discount rates, and market multiples. Therefore, performing audit procedures to evaluate the reasonableness of these estimates and assumptions involved a high degree of auditor judgment and increased extent of effort, including the need to involve our fair value specialists.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the International Interactive forecasts, discount rates, and market multiples used by management to estimate the fair value of the International Interactive reporting unit included the following, among others:

•We tested the effectiveness of controls over determining the fair value of the Company’s International Interactive reporting unit, including controls over the International Interactive forecasts and the selection of discount rates and market multiples.

•We evaluated management’s ability to accurately project the International Interactive forecasts by performing a retrospective review of actual results to management’s historical forecasts.

•We evaluated the reasonableness of management’s projected International Interactive forecasts by:

◦Comparing the International Interactive forecasts to information included in the Company’s communications to the Board of Directors, industry reports, and analyst reports for the Company and certain of its peer companies;

◦Comparing the International Interactive forecasts to historical financial results;

◦Evaluating the impact of changes in the regulatory environment on management’s forecasts;

◦Conducting inquiries with management; and

◦Evaluating whether the International Interactive forecasts were consistent with evidence obtained in other areas of the audit.

•With the assistance of our fair value specialists, we evaluated the reasonableness of the International Interactive discount rate and market multiples by:

◦Testing the inputs underlying the determination of the discount rate and testing the mathematical accuracy of the calculation;

◦Developing a range of independent estimates and comparing those to the discount rate selected by management;

◦Testing the source information underlying the determination of the market multiples; and

◦Developing a range of independent estimates and comparing those to the market multiples selected by management.
