(1)	Represents the vesting of 93,677.46542 performance share units (PSUs) granted on October 3, 2022, under the MGM Resorts International (Company) 2022 Omnibus Incentive Plan (Plan). Each PSU represented the right to receive between 0 and 1.6 shares of Company common stock depending upon the performance of the common stock from the grant date to the date that was three years after the grant date (Vesting Date), relative to a target price of $41.83 (Target Price). The Target Price is equal to 125% of the average closing price of Company common stock over the 60-calendar day period ending on the grant date. The number of shares issued per PSU, 0.8628210 shares, was calculated by dividing the ending average stock price by the Target Price. For this purpose, the ending average stock price is the average closing price of Company common stock over the 60-day period ending on the Vesting Date, as adjusted to include dividends paid during the term of the PSU.
(2)	Represents the vesting of 88,048.077 PSUs granted on October 3, 2022, under the Plan. The number of shares awarded at the end of the performance period was based upon the Company's three-year total shareholder return (TSR) compared to the TSRs of the constituents of the S&P 500 Index.
(3)	Restricted Stock Units ("RSUs") granted under the MGM Resorts International ("Company") 2022 Omnibus Incentive Plan. Each RSU represents the right to receive, following vesting, one share of Company common stock. The RSUs vest in four equal annual installments commencing on the first anniversary of the grant date.
(4)	RSUs granted under the Plan. Each RSU represents the right to receive, following vesting, one share of Company common stock. The RSUs will vest in four equal annual installments commencing on the first anniversary of the grant date.
