Bally's Corp

Management’s Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our chief executive officer (principal executive officer) and chief financial officer (principal financial officer), conducted an evaluation of the effectiveness of our disclosure controls and procedures as of the end of the year ended December 31, 2024, as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Based on this evaluation, our chief executive officer and chief financial officer have concluded that during the period covered by this report, the Company’s disclosure controls and procedures were not effective due to a material weakness in the Company’s internal control over financial reporting described below.

Notwithstanding the ineffective disclosure controls and procedures as a result of the identified material weakness, our chief executive officer and chief financial officer have concluded that the consolidated financial statements in this Annual Report on Form 10-K present fairly, in all material respects, the Company’s financial position, results of operations and cash flows in accordance with generally accepted accounting principles in the United States of America (U.S. GAAP).

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act as a process designed by, or under the supervision of, the Company’s principal executive and principal financial officers and effected by the Company’s Board, management and other personnel to provide reasonable assurance regarding the reliability of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that:

•pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the Company;

•provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and

•provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risks that controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate. Management assessed the effectiveness of its Company’s internal control over financial reporting as of December 31, 2024. In making this assessment, management used the criteria established in the Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“the COSO framework”). Based on evaluation under the criteria established in the COSO framework, management determined, based upon the existence of the material weakness described below, we did not maintain effective internal control over financial reporting as of December 31, 2024.

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that a reasonable possibility exists that a material misstatement of our annual or interim financial statements would not be prevented or detected on a timely basis.

Deloitte & Touche LLP, the Company’s independent registered public accounting firm that audited the Consolidated Financial Statements for the year ended December 31, 2024, issued an attestation report on the Company’s internal control over financial reporting which immediately follows this report.

Material Weakness Identified

We lack segregation of duties over the preparation, review, and recording of journal entries within our International Interactive reportable segment. The failure to maintain appropriate segregation of duties has a pervasive impact and consequently, this deficiency impacts control activities over all financial statement account balances, classes of transactions, and disclosures within the International Interactive reportable segment. This material weakness was originally identified as of December 31, 2023 and was not remediated as of December 31, 2024.

During 2024, Management developed and implemented incremental or enhanced controls to remediate the material weakness, including educating control owners within our International Interactive reportable segment of the appropriate design elements of journal entry controls, enhancing our policy around documented approvals of journal entries, and implementing a monitoring control over journal entries. However, controls over certain journal entries were not designed effectively and others were determined not to be operating effectively as of December 31, 2024. Management remains focused on designing and implementing effective measures to improve our internal controls over financial reporting and remediate the material weakness. Management has developed a detailed plan for remediation, which includes:

•Continuing to educate control owners within the International Interactive reportable segment of the appropriate design elements of journal entry controls and enforcing policies requiring independent preparers and reviewers.

•Implementing a new enterprise resource planning (“ERP”) system, which we believe will enhance the flow of financial information, improve data management and control and will enable us to remediate segregation of duties over journal entries by systematically requiring an independent preparer and reviewer of each journal entry. As the implementation of the new ERP system progresses, we may change our processes and procedures which, in turn, could result in further changes to our internal control over financial reporting. As such changes occur, we will evaluate quarterly whether such changes materially affect our internal control over financial reporting.

While we believe our remediation efforts above will improve the effectiveness of our internal control over financial reporting, we cannot assure that the measures will be sufficient to remediate the material weakness we have identified or will prevent potential future material weaknesses. The material weakness cannot be considered remediated until applicable controls have operated for a sufficient period of time and management has concluded, through testing, that these controls are operating effectively. Accordingly, we will continue to monitor and evaluate the effectiveness of our internal control over financial reporting.

Remediation of Previously Identified Material Weaknesses

As disclosed in Part II, Item 9A., “Controls and Procedures,” in our Annual Report on Form 10-K for the year ended December 31, 2023, we identified control deficiencies during 2023 that constituted material weaknesses relating to: (1) an insufficient number of personnel with the appropriate level of accounting knowledge, training and experience to appropriately analyze, record and disclose significant and complex accounting and tax matters timely and accurately, and (2) ineffective review of account reconciliations and account analysis controls, including the controls to validate the completeness and accuracy of information used in the performance of those controls, within the International Interactive reportable segment. We reinforced remediation efforts throughout 2024 and monitored operating effectiveness on a quarterly basis. As of December 31, 2024, Management concluded these material weaknesses were remediated. Specifically, the following plans were implemented and determined to be operating effectively:

•Realigned resources and, where applicable, hired qualified staff or used third-party subject matter experts with the appropriate level of experience and training to segregate key functions within our financial processes in order to support the review of significant and complex accounting matters, including appropriately analyzing, recording and disclosing accounting matters timely and accurately, specifically around assumptions used in certain estimates.

•Strengthened controls over account reconciliations and account analyses within our International Interactive reportable segment to support financial reporting requirements. Specifically, implemented or enhanced controls over report logic, data input, spreadsheet calculation and extract procedures over information used in the performance of controls to ensure completeness and accuracy.

Changes in Internal Control over Financial Reporting

Other than the material weakness noted above and the remediation of the previously disclosed material weaknesses, there has been no change in our internal control over financial reporting that occurred during the quarter ended December 31, 2024 covered by this Annual Report on Form 10-K that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

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

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Bally's Corporation and subsidiaries (the "Company") 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 (COSO). In our opinion, because of the effect of the material weakness identified below on the achievement of the objectives of the control criteria, the Company has not maintained effective internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2024, of the Company and our report dated March 17, 2025, expressed an unqualified opinion on those financial statements.

Basis for Opinion

The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. 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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Material Weakness

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the company’s annual or interim financial statements will not be prevented or detected on a timely basis. The following material weakness has been identified and included in management's assessment:

Management identified a material weakness related to the lack of segregation of duties over the preparation, review, and recording of journal entries within the International Interactive reportable segment. The failure to maintain appropriate segregation of duties has a pervasive impact and consequently, this deficiency impacts control activities over all financial statement account balances, classes of transactions, and disclosures within the International Interactive reportable segment.

This material weakness was considered in determining the nature, timing, and extent of audit tests applied in our audit of the consolidated financial statements as of and for the year ended December 31, 2024, of the Company, and this report does not affect our report on such financial statements.
