MGM GROWTH PROPERTIES OPERATING PARTNERSHIP LP ANNOUNCES PRICING OF $350 MILLION SENIOR NOTES OFFERING

Las Vegas, Nevada, September 7, 2017 — MGM Growth Properties Operating Partnership LP and MGP Finance Co-Issuer, Inc. (together, the “Issuers”), consolidated subsidiaries of MGM Growth Properties LLC (NYSE: MGP) (the “Company”), have priced $350 million in aggregate principal amount of 4.500% senior notes due 2028 (the “notes”) in a private placement at par. The offering is expected to close on September 21, 2017, subject to customary closing conditions.

The Issuers plan to use the net proceeds of the offering to pay MGM Resorts International (“MGM”) a portion of the $1,187.5 million purchase price for the long-term leasehold interest and real property improvements related to the MGM National Harbor casino resort (the “MGM National Harbor Transaction”), including to refinance indebtedness expected to be assumed by a subsidiary of the Company in connection with the transaction. The MGM National Harbor Transaction is expected to close in the fourth quarter of 2017, subject to regulatory approvals and other customary closing conditions.

The offering of the notes is not conditioned upon the successful completion of the MGM National Harbor Transaction. If the MGM National Harbor Transaction does not occur for any reason, the Issuers intend to use the net proceeds of the offering for working capital and general corporate purposes, which may include acquisitions, the repayment of indebtedness and other general business purposes.

The notes offered will not be registered under the Securities Act of 1933, as amended (the “Securities Act”), or any state securities laws and may not be offered or sold in the United States or to any U.S. persons absent registration under the Securities Act, or pursuant to an applicable exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and applicable state securities laws. The notes have been offered only to “qualified institutional buyers” under Rule 144A of the Securities Act or, outside the United States, to persons other than “U.S. persons” in compliance with Regulation S under the Securities Act.

This press release does not constitute an offer to sell or a solicitation of an offer to buy the notes, nor shall there be any offer, solicitation or sale of any notes in any jurisdiction in which such offer, solicitation or sale would be unlawful. The Company gives no assurance that the proposed offering can be completed on any terms.
