MGM RESORTS INTERNATIONAL REPORTS FOURTH QUARTER AND FULL YEAR

FINANCIAL AND OPERATING RESULTS

Announces 15% increase to Quarterly Cash Dividend, a new $3 billion Share Repurchase Program and Anticipated Launch of a Modified Dutch Auction Tender Offer to Purchase up to $1.25 billion of Common Stock Tomorrow at a Range Between $29 and $34 per Share

Las Vegas, Nevada, February 12, 2020 – MGM Resorts International (NYSE: MGM) (“MGM Resorts” or the “Company”) today reported financial results for the quarter and year ended December 31, 2019.

Fourth Quarter 2019 Financial Highlights:

Consolidated Results

“We are proud of the progress we made during 2019 as we took important steps to evolve our organization,” said Jim Murren, Chairman and CEO of MGM Resorts. “However, our fourth quarter results were below our expectations, primarily due to lower than expected hold, weakness in Far East baccarat, and certain one-time items. All other dimensions of our business in Las Vegas performed on or ahead of plan. For full year 2019, we generated strong consolidated net revenue and Adjusted EBITDAR, which increased 10% and 6%, respectively, year over year. We are also executing on our stated MGM 2020 plan, which is realizing material cost savings and revenue enhancements and transforming the way we operate to position MGM Resorts for future growth and long-term value creation. Finally, we were pleased to return more than $1.3 billion to shareholders in the form of dividends and buybacks in 2019.”

“During the year, our team made meaningful strides in implementing our asset-light strategy to optimize our portfolio, strengthen our balance sheet and enhance free cash flow. This strategy is best positioning MGM Resorts for the future by providing the flexibility to invest in higher return growth opportunities. Following the monetization of the real estate of Bellagio and the sale of Circus Circus Las Vegas, we continued our momentum into the first quarter of 2020 with our announcement to monetize the real estate of MGM Grand Las Vegas. Our previously announced transactions are expected to provide total net cash proceeds to MGM Resorts of $8.2 billion, a portion of which we used to retire $3.1 billion of debt in the fourth quarter. We remain committed to reducing our net domestic financial leverage, excluding MGP, to approximately 1 time by year end 2020. We will have one of the strongest balance sheets in our industry and also the strongest in our recent history. Furthermore, with the expected launch of a modified Dutch auction tender offer tomorrow, we expect to continue to return value to shareholders on an efficient and expedited basis.”

Mr. Murren concluded, “Looking ahead, we remain focused on monetizing our remaining owned real estate assets, which we expect will allow us to invest into high growth initiatives such as Japan and sports, as well as continue to further fortify our balance sheet and return capital to shareholders.”

2020 Financial Targets

MGM Resorts expects several headwinds in calendar year 2020, certain of which the Company believes are unpredictable within an appropriate range of accuracy. As a result of the increased volatility in our business due to coronavirus as well as the market-wide weakness in Far East baccarat in Las Vegas, MGM Resorts believes it is appropriate to withdraw its fiscal 2020 full year financial targets. Our Macau casinos are currently closed.

“We have made significant changes as a company since 2018, when we announced our financial targets. We have advanced our transition to a more asset light business model and are successfully continuing to execute on our MGM 2020 plan,” said Corey Sanders, Chief Financial Officer and Treasurer of MGM Resorts. “While we are encouraged with the long-term outlook in most of our key segments, and are especially pleased with our underlying domestic business performance, we believe it is appropriate to withdraw our 2020 financial targets. Notwithstanding this decision, we are committed to growing free cash flow and Adjusted EBITDAR, moderating our capital expenditures

and reducing the number of shares outstanding. The repurchase announced today is evidence of our continued confidence in our overall business and strategy, and we continue to believe in the value potential of MGM Resorts as we navigate the current environment.”

Page 7 of 16

described in this communication or at all. The tender offer will be made only pursuant to an offer to purchase, letter of transmittal and related materials that the Company expects to distribute to its stockholders and file with the Securities and Exchange Commission upon commencement of the tender offer. STOCKHOLDERS AND INVESTORS SHOULD READ CAREFULLY THE OFFER TO PURCHASE, LETTER OF TRANSMITTAL AND RELATED MATERIALS BECAUSE THEY WILL CONTAIN IMPORTANT INFORMATION, INCLUDING THE VARIOUS TERMS OF, AND CONDITIONS TO, THE TENDER OFFER.

1.“Adjusted EPS” is diluted earnings or loss per share adjusted to exclude preopening and start-up expenses, property transactions, net, gain on Bellagio transaction, restructuring costs (which represents costs related to severance, accelerated stock compensation expense, and consulting fees directly related to the operating model component of the MGM 2020 Plan), gain or loss on retirement of long-term debt, foreign currency gain or loss related to MGM China’s U.S. dollar-denominated debt,  the Company’s share of mark-to-market adjustments related to CityCenter’s interest rate swaps recorded within non-operating items from unconsolidated affiliates, and business interruption insurance proceeds.

Adjusted EPS is a non-GAAP measure and is presented solely as a supplemental disclosure to reported GAAP measures because management believes this measure is useful in providing period-to-period comparisons of the results of the Company’s continuing operations to assist investors in reviewing the Company’s operating performance over time. Management believes that while certain items excluded from Adjusted EPS may be recurring in nature and should not be disregarded in evaluating the Company’s earnings performance, it is useful to exclude such items when comparing current performance to prior periods because these items can vary significantly depending on specific underlying transactions or events. Also, management believes certain excluded items, such as restructuring costs and items further discussed in footnote 2 below, may not relate specifically to current operating trends or be indicative of future results. Adjusted EPS should not be construed as an alternative to GAAP earnings per share as an indicator of the Company’s performance. In addition, Adjusted EPS may not be defined in the same manner by all companies and, as a result, may not be comparable to similarly-titled non-GAAP financial measures of other companies. A reconciliation of Adjusted EPS to diluted earnings per share can be found under “Adjusted Diluted Earnings Per Share” included in this release.

2.“Adjusted EBITDAR” is earnings before interest and other non-operating income (expense), taxes, depreciation and amortization, preopening and start-up expenses, gain on Bellagio transaction, restructuring costs (which represents costs related to severance, accelerated stock compensation expense, and consulting fees directly related to the operating model component of the MGM 2020 Plan), rent expense associated with triple net operating and ground leases, income from unconsolidated affiliates related to investments in REITs, and property transactions, net. Management utilizes “Adjusted Property EBITDAR” as the primary profit measures for its reportable segments and underlying operating segments. Adjusted Property EBITDAR is a measure defined as Adjusted EBITDAR before corporate expense and stock compensation expense, which are not allocated to each operating segment, and before rent expense related to the master lease with MGM Growth Properties that eliminates in consolidation. The Company manages capital allocation, tax planning, stock compensation, and financing decisions at the corporate level. “Adjusted Property EBITDAR margin” is Adjusted Property EBITDAR divided by related segment net revenues.

“Table Games Hold Adjusted Las Vegas Strip Resorts Adjusted Property EBITDAR” and “VIP Table Games Hold Adjusted MGM China Adjusted Property EBITDAR” are supplemental non-GAAP financial measures, that, in addition to the reasons described above for the presentation of Adjusted  Property EBITDAR, are presented to adjust for the impact of certain variances in table games and VIP table games’ win percentages compared to the mid-point of the expected ranges. Table Games Hold Adjusted Las Vegas Strip Resorts Adjusted Property EBITDAR is calculated by applying a win percentage of 30.0% for Baccarat and 21.0% for non-Baccarat games to the respective table games drops for the quarter, which represents the mid-point of the expected ranges of 25.0% to 35.0% for Baccarat and 19.0% to 23.0% for non-Baccarat at the Las Vegas Strip Resorts properties. VIP Table Games Hold Adjusted MGM China Adjusted Property EBITDAR is based on applying a VIP Rolling Chip win percentage of 2.95% to the VIP Rolling Chip volume, which represents the mid-point of the expected normal range of 2.6% to 3.3% for MGM China. Table Games Hold Adjusted Las Vegas Strip Resorts Adjusted Property EBITDAR and VIP Table Games Hold Adjusted MGM China Adjusted Property EBITDAR are also adjusted for the gaming taxes, VIP commissions, bad debt expense, discounts and other incentives that would have been incurred or avoided when applying the win percentages noted above to the respective gaming volumes.

Adjusted EBITDAR information is a valuation metric, should not be used as an operating metric, and is presented solely as a supplemental disclosure to reported GAAP measures because management believes these measures are widely used by analysts , lenders, financial institutions, and investors as a principal basis for the valuation of gaming companies. Management believes that while items excluded from Adjusted EBITDAR, Adjusted Property EBITDAR, and Adjusted Property EBITDAR margin may be recurring in nature and should not be disregarded in evaluation of the Company’s earnings performance, it is useful to exclude such items when analyzing current results and trends compared to other periods because these items can vary significantly depending on specific underlying transactions or events that may not be comparable between the periods being presented. Also, management believes excluded items may

Page 8 of 16

not relate specifically to current trends or be indicative of future results. For example, preopening and start-up expenses will be significantly different in periods when the Company is developing and constructing a major expansion project and will depend on where the current period lies within the development cycle, as well as the size and scope of the project(s). Property transactions, net includes normal recurring disposals, gains and losses on sales of assets related to specific assets within the Company’s resorts, but also includes gains or losses on sales of an entire operating resort or a group of resorts and impairment charges on entire asset groups or investments in unconsolidated affiliates, which may not be comparable period over period. In addition, management changed its non-GAAP measures in the fourth quarter of 2019, including recasting prior periods, as a result of the closing of the Bellagio real estate transaction and the MGM Grand/Mandalay Bay real estate transaction that is expected to close in the first quarter of 2020, to exclude rent expense associated with triple net operating leases and ground leases. Management believes excluding rent expense associated with triple net operating leases and ground leases provides useful information to analysts, lenders, financial institutions, and investors when valuing the Company, as well as comparing  the Company’s results to other gaming companies, without regard to differences in capital structure and leasing arrangements since the operations of other gaming companies may or may not include triple net operating leases or ground leases. However, as discussed herein, Adjusted EBITDAR and Adjusted Property EBITDAR should not be viewed as measures of overall operating performance, considered in isolation, or as an alternative to net income, because these measures are not presented on a GAAP basis and exclude certain expenses, including the rent expense associated with the Company’s triple net operating and ground leases, and are provided for the limited purposes discussed herein.

Adjusted EBITDAR, Adjusted Property EBITDAR, Adjusted Property EBITDAR margin, Table Games Hold Adjusted Las Vegas Strip Resorts Adjusted Property EBITDAR and VIP Table Games Hold Adjusted MGM China Adjusted Property EBITDAR should not be construed as alternatives to operating income or net income, as indicators of the Company’s performance; or as alternatives to cash flows from operating activities, as measures of liquidity; or as any other measure determined in accordance with generally accepted accounting principles. The Company has significant uses of cash flows, including capital expenditures, interest payments, taxes, real estate triple net lease and ground lease payments, and debt principal repayments, which are not reflected in Adjusted EBITDAR, Adjusted Property EBITDAR, Adjusted Property EBITDAR margin, Table Games Hold Adjusted Las Vegas Strip Resorts Adjusted Property EBITDAR, or VIP Table Games Hold Adjusted MGM China Adjusted Property EBITDAR. Also, other companies in the gaming and hospitality industries that report Adjusted EBITDAR, Adjusted Property EBITDAR, Adjusted Property EBITDAR margin, Table Games Hold Adjusted Las Vegas Strip Resorts Adjusted Property EBITDAR, or VIP Table Games Hold Adjusted MGM China Adjusted Property EBITDAR information may calculate Adjusted EBITDAR, Adjusted Property EBITDAR, Adjusted Property EBITDAR margin, Table Games Hold Adjusted Las Vegas Strip Resorts Adjusted Property EBITDAR, or VIP Table Games Hold Adjusted MGM China Adjusted Property EBITDAR in a different manner and such differences may be material.

A reconciliation of GAAP net income (loss) to Adjusted EBITDAR is included in the financial schedules in this release. This press release also includes references to target financial measures and goals (including targeted Adjusted EBITDAR and targeted net leverage), which are not presented as forecasts or projections of expected future performance.

3.“Table Games Hold Adjusted Las Vegas Strip Resorts Net Revenues” and “VIP Table Games Hold Adjusted MGM China Net Revenues” are additional supplemental non-GAAP financial measures that are presented to adjust Las Vegas Strip Resorts net revenues and MGM China net revenues for the impact of certain variances in table games and VIP table games’ win percentages compared to the mid-point of the expected ranges, as described in footnote 2 above. Table Games Hold Adjusted Las Vegas Strip Resorts Net Revenues and VIP Table Games Hold Adjusted MGM China Net Revenues are also adjusted for the VIP commissions, discounts and other incentives that would have been incurred or avoided when applying the win percentages noted in footnote 2 above to the respective gaming volumes. Management believes Table Games Hold Adjusted Las Vegas Strip Resorts Net Revenues and VIP Table Games Hold Adjusted MGM China Net Revenues present consistent measures in providing period-to-period comparisons and are useful measures in assisting investors evaluating the Company’s operating performance. Table Games Hold Adjusted Las Vegas Strip Resorts Net Revenues and VIP Table Games Hold Adjusted MGM China Net Revenues should not be construed as alternatives to GAAP net revenues, as indicators of the Company’s performance, or as any other measure determined in accordance with generally accepted accounting principles. Reconciliations of GAAP net revenues to Table Games Hold Adjusted Las Vegas Strip Resorts Net Revenues and VIP Table Games Hold Adjusted MGM China Net Revenues are included in the financial schedules in this release.

4.REVPAR is hotel revenue per available room.

5.CityCenter non-GAAP Measure

“Adjusted EBITDA” is earnings before interest and other non-operating income (expense), taxes, depreciation and amortization, preopening and start-up expenses, restructuring costs (which represents costs related to severance, accelerated stock compensation expense, and consulting fees directly related to the operating model component of the MGM 2020 Plan), and property transactions, net. Management utilizes Adjusted EBITDA as the primary profit measures for CityCenter. Adjusted EBITDA is a non-GAAP measure and is presented solely as a supplemental disclosure to reported GAAP measures. Management believes that while certain

Page 9 of 16

items excluded from Adjusted EBITDA may be recurring in nature and should not be disregarded in evaluating CityCenter’s earnings performance, it is useful to exclude such items when comparing current performance to prior periods because these items can vary significantly depending on specific underlying transactions or events. Also, management believes certain excluded items, such as restructuring costs and items further discussed above, may not relate specifically to current operating trends or be indicative of future results. Adjusted EBITDA should not be construed as alternatives to operating income or net income, as indicators of the Company’s performance; or as alternatives to cash flows from operating activities, as measures of liquidity; or as any other measure determined in accordance with generally accepted accounting principles. A reconciliation of GAAP net income (loss) to Adjusted EBITDA is included in the financial schedules in this release.
