AN IMPORTANT MESSAGE FROM

WYNN RESORTS, LIMITED

Elaine Wynn Urges Wynn Resorts Stockholders to

Wait for the GOLD Proxy Card for the

Wynn Resorts 2015 Annual Meeting of Stockholders

Dear Fellow Wynn Resorts Stockholders:

Soon you will be receiving a proxy statement from Wynn Resorts, Limited in connection with its 2015 Annual Meeting of Stockholders, scheduled to be held on April 24, 2015. Wynn Resorts will seek your vote for the election of John J. Hagenbuch and J. Edward Virtue to the board. Thereafter, you will be receiving my proxy statement seeking your vote for the election of me, Elaine Wynn, and one of the company’s nominees to the board.

I strongly urge you NOT to vote any proxy card sent to you by Wynn Resorts, and to wait for my proxy materials and the GOLD proxy card.

I have served tirelessly on your behalf for the past 13 years as a director and co-founder of Wynn Resorts. The board recently took action to shrink the size of the board by one director and thereby exclude me from the board despite my immense industry knowledge and expertise, and my role building and promoting the Wynn business and brand through the years. This action was without merit and therefore, I have decided to file my nomination and seek your vote for my re-election to the board.

I have more than 40 years of gaming and hospitality experience and have been an integral part of helping the company grow into the successful enterprise it is today. No one at the company, other than our Chairman and CEO, is more knowledgeable about its history, its operations, its customers, or its award-winning staff. Moreover, I am the last remaining woman on the board. The appalling lack of diversity that the board’s recommendation would bring is clearly unacceptable. We are a global consumer-oriented company that strives to appeal to both men and women and, as a result, it is critical that the views of women be represented on our board.

I am also the third-largest stockholder of Wynn Resorts, with more than 9.5 million shares, representing a 9.4% interest in the company. It is clear that my interests are very much aligned with the interests of you, my fellow stockholders. Given my substantial stock holdings in the company, you can be assured that I am keenly focused on viewing every board action through the lens of generating overall stockholder value.

My unique history with Wynn Resorts has afforded me a strong, independent voice on the board. I do not simply toe the party line and instead hold our management team, including our Chairman and CEO, accountable to our stockholders. The board’s action to exclude a strong and knowledgeable voice may make for a more homogeneous and compliant board, but I believe that is not at all in the best interests of our stockholders.

I urge you NOT to return any proxy card that you receive from Wynn Resorts or any materials giving your broker, banker or trustee authority to execute any proxy in favor of the nominees of Wynn Resorts.

Please wait until you receive my proxy materials and the GOLD proxy card before you cast your vote in connection with the 2015 Annual Meeting of Stockholders.

Chris and I will be there!
