MGM RESORTS INTERNATIONAL ANNOUNCES PROPOSED PRIVATE OFFERING BY CITYCENTER HOLDINGS

Las Vegas, Nevada, January 10, 2011 — MGM Resorts International (NYSE: MGM) today announced that CityCenter Holdings, LLC, a joint venture which is 50% owned by a wholly-owned subsidiary of the Company and 50% owned by Infinity World Development Corp. (a wholly owned subsidiary of Dubai World), proposes to offer $1.1 billion in aggregate principal amount of first and second lien notes in a private placement. CityCenter plans to use the net proceeds from the offering to reduce its obligations under its existing credit facility in connection with amending and restating the credit facility to, among other things, extend the maturity of the remaining loans for four years.

The notes proposed to be 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 will be 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.
