Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions (See General Instruction A.2 below):

On March 31, 2016, Gaming and Leisure Properties, Inc., a Pennsylvania corporation (the “Company”), announced that it has priced and upsized its previously announced underwritten public offering (the “Offering”) from 19,000,000 shares of its common stock, par value $0.01 per share (the “Common Stock”), to 25,000,000 shares of its Common Stock (the “Shares”). A copy of the press release is attached as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.

In connection with the Offering, the Company entered into an underwriting agreement (the “Underwriting Agreement”) with Merrill Lynch, Pierce, Fenner & Smith Incorporated, J.P. Morgan Securities LLC and Wells Fargo Securities, LLC, as representatives of the several underwriters listed on Schedule I thereto (the “Underwriters”), pursuant to which the Company agreed to issue and sell to the Underwriters the Shares, at a public offering price of $30.00 per share. The Underwriting Agreement contains customary representations, warranties and covenants by the Company. It also provides for customary indemnification by the Company for losses or damages arising out of or in connection with the sale of the Shares.

The Company also granted the Underwriters a 30-day option to purchase up to 3,750,000 additional shares of its Common Stock. The Offering is expected to close on April 6, 2016, subject to customary closing conditions, with estimated net proceeds to the Company expected to be approximately $718 million (or $826 million if the underwriters exercise their option to purchase additional shares in full).

The Offering was made pursuant to a prospectus supplement and an accompanying prospectus related to the Company’s effective shelf registration statement on Form S-3 (File No. 333-210423), each of which has been filed with the Securities and Exchange Commission.

The foregoing is a summary description of certain terms of the Underwriting Agreement and is qualified in its entirety by the text of the Underwriting Agreement attached as Exhibit 1.1 to this Current Report on Form 8-K and incorporated herein by reference.

This Current Report on Form 8-K does not constitute an offer to sell, or a solicitation of an offer to buy, any of the Company’s securities, including, without limitation, those securities proposed to be offered and sold pursuant to the preliminary prospectus supplement, final prospectus supplement and registration statement described above.
