“2019 was a year of significant growth for MGP as we closed three accretive transactions, acquiring the real estate assets of Empire City Casino from a third party, selling the previously acquired operations of Northfield Park to MGM and monetizing the Park MGM improvements, which resulted in $160 million of additional rent and further demonstrated the power of our leading partnership with our tenant, MGM Resorts,” said James Stewart, CEO of MGP. “2020 is off to an exciting start as we expect to complete the transaction to acquire majority ownership of MGM Grand Las Vegas, an iconic casino resort on the Las Vegas Strip, in the near term and we are looking forward to continuing to seek opportunities to grow our portfolio this year and executing on all facets of our business plan to prudently deliver shareholder value.”

On January 15, 2020, the Operating Partnership made a cash distribution of $147.3 million relating to the fourth quarter dividend, $93.9 million of which was paid to subsidiaries of MGM and $53.4 million of which was paid to MGP. Simultaneously, MGP paid a cash dividend of $0.47 per share.

On November 22, 2019, the Company completed an offering of 30.0 million Class A shares in a registered public offering, of which 18.0 million settled at the closing of the offering for net proceeds of approximately $540.6 million, after deducting underwriting discounts and commissions, and 12.0 million which were sold pursuant to forward purchase agreements that settled between February 11 and February 13, 2020. In addition, as part of the MGP BREIT Venture transaction BREIT will purchase 4,891,395 Class A common shares from MGP pursuant to a registered direct offering, representing an aggregate investment of $150 million.

“2019 was marked by many significant achievements for MGP, highlighted by three dividend increases that resulted in an annualized dividend of $1.88 per share which represents a total increase of $0.09 per share year over year,” said Andy Chien, CFO of MGP. “We received strong support from the capital markets as demonstrated by the two successful follow-on equity offerings and the issuance of $750 million in senior notes. These capital market transactions positioned the balance sheet to expand our portfolio throughout the year and also provided the flexibility to fund future transactions, while remaining in our target leverage range.”

1 Funds From Operations (“FFO”) is net income (computed in accordance with U.S. GAAP), excluding gains and losses from sales or disposals of property (presented as property transactions, net), plus real estate depreciation, as defined by the National Association of Real Estate Investment Trusts.

2 Adjusted Funds From Operations (“AFFO”) is FFO as adjusted for amortization of financing costs and cash flow hedges; non-cash compensation expense; straight-line rent (which is defined as the difference between contractual rent and cash rent payments, excluding lease incentive asset amortization); amortization of lease incentive asset and deferred revenue relating to non-normal tenant improvements; acquisition-related expenses; non-cash ground lease rent, net; other expenses;

Page 4 of 8

loss on unhedged interest rate swaps, net; provision for income taxes related to the REIT; and other, net - discontinued operations.

3 Adjusted EBITDA is net income (computed in accordance with U.S. GAAP) as adjusted for gains and losses from sales or disposals of property (presented as property transactions, net); real estate depreciation; amortization of financing costs and cash flow hedges; non-cash compensation expense; straight-line rent; amortization of lease incentive asset and deferred revenue relating to non-normal tenant improvements; acquisition-related expenses; non-cash ground lease rent, net; other expenses; loss on unhedged interest rate swaps, net; other, net - discontinued operations; interest income; interest expense (including amortization of financing costs and cash flow hedges); and provision for income taxes.

FFO, FFO per unit, AFFO, AFFO per unit and Adjusted EBITDA are supplemental performance measures that have not been prepared in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) that management believes are useful to investors in comparing operating and financial results between periods. Management believes that this is especially true since these measures exclude real estate depreciation and amortization expense and management believes that real estate values fluctuate based on market conditions rather than depreciating in value ratably on a straight-line basis over time. The Company believes such a presentation also provides investors with a meaningful measure of the Company’s operating results in comparison to the operating results of other REITs. Adjusted EBITDA is useful to investors to further supplement AFFO and FFO and to provide investors a performance metric which excludes interest expense. In addition to non-cash items, the Company adjusts AFFO and Adjusted EBITDA for acquisition-related expenses. While we do not label these expenses as non-recurring, infrequent or unusual, management believes that it is helpful to adjust for these expenses when they do occur to allow for comparability of results between periods because each acquisition is (and will be) of varying size and complexity and may involve different types of expenses depending on the type of property being acquired and from whom.

FFO, FFO per unit, AFFO, AFFO per unit and Adjusted EBITDA do not represent cash flow from operations as defined by U.S. GAAP, should not be considered as an alternative to net income as defined by U.S. GAAP and are not indicative of cash available to fund all cash flow needs. Investors are also cautioned that FFO, FFO per unit, AFFO, AFFO per unit and Adjusted EBITDA as presented, may not be comparable to similarly titled measures reported by other REITs due to the fact that not all real estate companies use the same definitions.

Reconciliations of net income to FFO, AFFO and Adjusted EBITDA are included in this release.
