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 Annual 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.

MGM Grand Paradise gaming concession — Refer to Note 7 to the financial statements

Critical Audit Matter Description

Gaming in Macau is currently administered by the Macau Government through concessions awarded to six different concessionaires. On December 16, 2022, MGM Grand Paradise was awarded a ten-year concession contract to permit the operation of games of chance or other games in casinos in Macau, which commenced on January 1, 2023. MGM Grand Paradise is required, among other things, to pay a fixed annual premium and an annual variable premium based on the number of gaming tables and machines for the term of the gaming concession. Additionally, upon the commencement of the gaming concession, the gaming assets were temporarily transferred to MGM Grand Paradise for the duration of the concession term in return for annual payments determined by square meters of the reverted casino areas.

On January 1, 2023, MGM Grand Paradise recorded an intangible asset of $226 million for the right to conduct gaming and operate the reverted gaming equipment and gaming areas and a corresponding liability for the in-substance consideration to be paid over the concession term for such rights, which is the unconditional obligation of the fixed and variable annual premiums, as well as the payments related to the use of the reverted gaming assets. The initial value of the intangible asset and liability were measured as the present value of these payments as of January 1, 2023.

We identified the recording of an intangible asset and a corresponding liability for the MGM Grand Paradise gaming concession as a critical audit matter because assessment of the applicable accounting guidance, the determination of which fixed and variable annual premium payments represented unconditional obligations, and the determination of the present value of such payments (including the selection of the discount rate) involved challenging, subjective, and complex judgments. Therefore, auditing this matter, involved a higher degree of auditor judgment and subjectivity, including the involvement of specialists.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the recording of an intangible asset and a corresponding liability for the MGM Grand Paradise gaming concession included the following, among others:

•We tested the effectiveness of the controls over management’s assessment of the accounting and recording of the MGM Grand Paradise gaming concession intangible asset and corresponding liability, including management’s identification of which fixed and variable annual premium payments represented unconditional obligations, and the determination of the initial value of the intangible asset and corresponding liability, including the selection of the discount rate.

•We inspected the concession contract and the other underlying agreements related to the MGM Grand Paradise gaming concession. With the assistance of professionals in our firm having expertise in accounting for intangible assets, we evaluated the reasonableness of management’s accounting and judgments used by management to determine whether the recording of an intangible asset and a corresponding liability was appropriate for the MGM Grand Paradise gaming concession, and the identification of which fixed and variable annual premium payments represented unconditional obligations.

•With the assistance of our fair value specialists, we evaluated the reasonableness of management’s selected discount rate by:

◦Testing the market-based source information underlying the determination of the discount rate and the mathematical accuracy of the discount rate calculations.

◦Developing an independent estimate and comparing it to the discount rate selected by management.
