Wynn Resorts Announces Issuance and Sale of 5.3 Million Shares of Common Stock, Stephen A. Wynn’s Sale of 8.0 Million Shares of Common Stock, and Amendment of 2023 Indenture

LAS VEGAS, March 22, 2018 (BUSINESS WIRE) — Wynn Resorts, Limited (NASDAQ: WYNN) (the “Company”) announced today that it agreed to sell 5,300,000 newly issued shares of Company common stock (the “Common Stock”) at a price of $175 per share to Galaxy Entertainment Group in a public offering registered under the Securities Act of 1933, as amended (the “1933 Act”).

The Company intends to use the net proceeds from that offering to repay amounts to be borrowed under the 364-day term loan facility contemplated by the commitment letters that the Company entered into on March 9, 2018, with an affiliate of Deutsche Bank Securities in an aggregate principal amount of up to $800 million. Deutsche Bank Securities is acting as sole book-running manager for the offering of Common Stock by the Company.

On March 21, 2018, the Wynn Family Limited Partnership (“WFLP” and together with Stephen A. Wynn, the “Selling Stockholder”), an entity affiliated with Stephen A. Wynn (“Mr. Wynn”), sold an aggregate of 4,104,999 shares of Common Stock at a price of $180 per share in open market transactions pursuant to Rule 144 under the 1933 Act.

Additionally, following the Rule 144 open market transactions, on March 22, 2018, the Selling Stockholder entered into agreements to sell approximately 8.0 million shares of Common Stock in privately negotiated transactions, representing all of his remaining holdings of the Company’s Common Stock.

On March 20, 2018, the Company announced that its indirect wholly owned subsidiaries, Wynn Las Vegas, LLC and Wynn Las Vegas Capital Corp. (the “WLV Issuers”), had received the requisite consents to approve an amendment to the indenture (the “2023 Indenture”) governing the WLV Issuers’ 4.25% Senior Notes due 2023. The amendment conforms the definition of “change of control” relating to ownership of equity interests in the Company in the 2023 Indenture to the terms of the indentures governing the WLV Issuers’ other outstanding notes.

The Common Stock being sold by the Company will be issued pursuant to an effective registration statement filed with the SEC on November 8, 2016. Copies of the prospectus supplement, when available, may be obtained by visiting EDGAR on the SEC’s website at http://www.sec.gov.
