MGM GROWTH PROPERTIES LLC

MGM GROWTH PROPERTIES OPERATING PARTNERSHIP LP

UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL INFORMATION

MGM Growth Properties LLC (“MGP” or the “Company”) conducts its operations through and consolidates MGM Growth Properties Operating Partnership LP (the “Operating Partnership”). MGP is controlled and consolidated by MGM Resorts International (“MGM”). A wholly owned subsidiary of the Operating Partnership (the “Landlord”) leases substantially all of its real estate properties back to a wholly owned subsidiary of MGM (the “Tenant”) under a master lease agreement (the “Master Lease”).

On October 5, 2017, the Operating Partnership completed its acquisition of MGM National Harbor’s real estate assets (the “MGM National Harbor Transaction”) pursuant to which MGM National Harbor, LLC (“MGM National Harbor”), a subsidiary of MGM, assigned its real estate assets to the Operating Partnership in exchange for a combination of cash, the assumption of certain debt from MGM National Harbor and the issuance of Operating Partnership units by the Operating Partnership to MGM National Harbor. The Operating Partnership funded the MGM National Harbor Transaction, in part, with proceeds from the issuance and sale of Operating Partnership units to MGP (which MGP purchased with the net proceeds from the issuance and sale of 13,225,000 Class A shares of approximately $387.5 million on September 11, 2017 (the “MGP Equity Offering”)), as well as the net proceeds of $345.6 million from the issuance of the Operating Partnership’s 4.50% senior notes due 2028 on September 21, 2017 (the “Senior Notes” and, the issuance of Senior Notes together with the MGP Equity Offering, the “MGM National Harbor Financing Transactions”).

On April 4, 2018, MGP OH, Inc. (the “TRS”), a taxable real estate investment trust subsidiary of the Operating Partnership, entered into an agreement with Milstein Entertainment LLC to acquire 100% of the issued and outstanding limited liability company interests in Northfield Park Associates LLC (“Northfield Park”), which owns and operates the Hard Rock Rocksino Northfield Park for approximately $1.1 billion and on July 6, 2018 the TRS completed the acquisition of Northfield Park (the “Northfield Park Acquisition”). The Company funded the Northfield Park Acquisition with a combination of cash on hand and borrowings under the Operating Partnership’s senior secured credit facility including a $200 million draw on the Operating Partnership’s delayed draw senior secured term loan A facility and a $655 million draw under its senior secured revolving credit facility.

On September 18, 2018, the Company entered into an agreement to sell the operations of Northfield Park (“OpCo”) to a subsidiary of MGM for approximately $275 million plus net working capital adjustments, inclusive of cash, of approximately $6.4 million as of June 30, 2018. The TRS will concurrently liquidate and the real estate assets of Northfield Park will be transferred to the Landlord. The Landlord will lease such real estate assets to the Tenant pursuant to an amendment to the Master Lease (together with the OpCo sale, the “Northfield Park OpCo Disposition”).

NOTES TO UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL INFORMATION

1. Basis of Presentation

The unaudited pro forma condensed consolidated balance sheet as of June 30, 2018 gives effect to the Northfield Park Acquisition and the Northfield Park OpCo Disposition as if they had occurred on June 30, 2018. The unaudited pro forma condensed consolidated statements of operations for the year ended December 31, 2017 and six months ended June 30, 2018 give effect to the Northfield Park Acquisition, the Northfield Park OpCo Disposition, the MGM National Harbor Transaction and the MGM National Harbor Financing Transactions as if they had occurred on January 1, 2017. The unaudited pro forma condensed consolidated financial information gives effect to events that are (i) directly attributable to these transactions, (ii) factually supportable and (iii) with respect to the statements of operations, are expected to have a continuing impact on MGP’s and the Operating Partnership’s consolidated results.

The Northfield Park Acquisition has been accounted for using the acquisition method of accounting in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 805,Business Combinations(“ASC 805”), with the TRS as the accounting acquirer and based on the historical consolidated financial statements of MGP, the Operating Partnership and Northfield Park.

The Northfield Park OpCo Disposition is a transaction between legal entities under common control and has been accounted for under the common control subsections of ASC 805. Accordingly, the recognized assets and liabilities transferred shall be recorded by MGM on the same basis as that established by MGP. Any difference between the purchase price paid by MGM and the basis of the net assets sold by MGP and the Operating Partnership is recorded as an adjustment to equity and partners’ capital, respectively.

The pro forma adjustments represent management’s best estimates and are based upon currently available information and certain assumptions that MGP and the Operating Partnership believe are reasonable. MGP and the Operating Partnership are not aware of any material transactions with Northfield Park during the periods presented, hence adjustments to eliminate transactions between MGP, the Operating Partnership and Northfield Park have not been reflected in the unaudited pro forma condensed consolidated financial information.

The unaudited pro forma condensed consolidated financial information presented is for illustrative purposes only and is not necessarily indicative of the financial position or results of operations that would have been realized if the Northfield Park Acquisition, the Northfield Park OpCo Disposition, the MGM National Harbor Transaction and the MGM National Harbor Financing Transactions had been completed on the dates indicated, nor is it indicative of the future operating results or financial position of MGP and the Operating Partnership. The unaudited pro forma condensed consolidated financial information does not reflect any cost savings, operating synergies or revenue enhancements that the combined company may achieve as a result of the Northfield Park Acquisition and the Northfield Park OpCo Disposition, the costs necessary to achieve these cost savings, operating synergies and revenue enhancements, or the integration-related costs of MGP, the Operating Partnership and Northfield Park.

2. Calculation of Acquisition Consideration and Preliminary Purchase Price Allocation

The following table summarizes, as of June 30, 2018, the preliminary purchase price allocation of the acquisition consideration to the estimated fair values of the assets acquired and liabilities assumed, after giving effect to the Northfield Park Acquisition:

	Pro Forma June 30, 2018
	(in thousands)
Assets acquired:
Property and equipment used in operations	$	792,967
Cash and cash equivalents		34,108
Tenant and other receivables, net		6,986
Prepaid expenses and other assets		3,288
Other intangible assets		253,000
Goodwill		17,899
		1,108,248
Liabilities assumed:
Accounts payable, accrued expenses and other liabilities		(37,980	)
Deferred revenue		(13	)
		(37,993	)
Total acquisition consideration	$	1,070,255

8

Preliminary identifiable intangible assets consist of the following:

	Fair Value		Estimated Useful Life
	(in thousands)
Racing and gaming licenses	$	228,000		Indefinite-lived
Customer relationships		25,000		7 Years
	$	253,000

The preliminary purchase price allocation presented above is based upon all information currently available to us, and is based upon management’s preliminary estimates of fair value using valuation techniques including income, cost, and market approaches. The purchase price allocation is preliminary pending our final determination of the fair values of the assets acquired and liabilities assumed, which we expect will occur within one year of the closing date of the Northfield Park Acquisition. Any reallocation of the fair values of assets acquired and liabilities assumed prior to completion of the final purchase price allocation could have a material impact on our depreciation and amortization expenses and future results of operations.
