MGM RESORTS INTERNATIONAL RELEASES INVESTOR PRESENTATION

Evercore Group L.L.C. engaged as an independent advisor to MGM and its Board of Directors

LAS VEGAS, Nevada. – April 20, 2015 — MGM Resorts International (NYSE: MGM) today announced that it has published an investor presentation in connection with its 2015 annual meeting of shareholders, to be held on May 28, 2015. The presentation is available on the Company’s website www.mgmresorts.com under the Investors section and is being filed today with the Securities and Exchange Commission (the “SEC”).

The Company also announced that Evercore Group L.L.C. has been added as an independent advisor to its team of existing advisors to assist MGM and its Board of Directors in its continuous process of actively evaluating all strategic initiatives for the Company, including a potential REIT conversion.

In its investor presentation, MGM outlines the Company’s strong track record and details the reasons why it believes Land & Buildings’ proxy fight is unwarranted, ill-conceived and not in the best interests of shareholders. The presentation focuses on the following:

• MGM has delivered above industry average returns and is well positioned for continued growth

• MGM has a history of value-generating strategic initiatives and delivering on commitments to drive strong performance

• The MGM Board has the right balance of independence, experience and necessary skills to oversee ongoing execution of the Company’s strategy and continue to drive sustainable value

• The Directors targeted by Land & Buildings all bring vital and unique skills that greatly contribute to the oversight of our complex and diverse global operations

• The proposed Board changes reflect a lack of understanding of the importance of diversity that has strengthened the Company and added value for shareholders

• Land & Buildings’ nominees are tied to a proposal that has a narrow, short-term focus and makes numerous financial, structural and tax assumptions that appear unsupported or are factually incorrect, which calls into question their credibility

• As a part of its regular and ongoing Board strategic review process, MGM has and will continue to actively evaluate strategic options for the Company that drive sustainable value for shareholders

MGM recommends that shareholders vote FOR the election of MGM’s highly qualified nominees on the WHITE proxy card.
