Disclosure Controls and Procedures

Our Chief Executive Officer (principal executive officer) and Chief Financial Officer (principal financial officer) have concluded that our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (“the Exchange Act”)) were effective as of December 31, 2025 to provide reasonable assurance that information required to be disclosed in the Company’s reports under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC rules and regulations and to provide that such information is accumulated and communicated to management to allow timely decisions regarding required disclosures. This conclusion is based on an evaluation as required by Rules 13a-15(b) and 15d-15(b) under the Exchange Act conducted under the supervision and participation of the principal executive officer and principal financial officer along with company management.

Management’s Annual Report on Internal Control over Financial Reporting

Management’s Responsibilities

Management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Sections 13a-15(f) and 15d-15(f) of the Exchange Act) for MGM Resorts International and subsidiaries (the “Company”).

Objective of Internal Control over Financial Reporting

In establishing adequate internal control over financial reporting, management has developed and maintained a system of internal control, policies and procedures designed to provide reasonable assurance that information contained in the accompanying consolidated financial statements and other information presented in this annual report is reliable, does not contain any untrue statement of a material fact or omit to state a material fact, and fairly presents in all material respects the financial condition, results of operations and cash flows of the Company as of and for the periods presented in this annual report. These include controls and procedures designed to ensure that this information is accumulated and communicated to the Company’s management, including its principal executive officer and principal financial officer, as appropriate for all timely decisions regarding required disclosure. Significant elements of the Company’s internal control over financial reporting include, for example:

• Hiring skilled accounting personnel and training them appropriately;

• Written accounting policies;

• Written documentation of accounting systems and procedures;

• Segregation of incompatible duties;

• Internal audit function to monitor the effectiveness of the system of internal control; and

• Oversight by an independent Audit Committee of the Board of Directors.

Management’s Evaluation

Management, with the participation of the Company’s principal executive officer and principal financial officer, has evaluated the Company’s internal control over financial reporting using the criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

Based on its evaluation as of December 31, 2025, management believes that the Company’s internal control over financial reporting is effective in achieving the objectives described above.
