Item 1.01. Entry into a Material Definitive Agreement.

On July 11, 2011, Gulfport Energy Corporation (the “Company”) entered into an Underwriting Agreement with Credit Suisse Securities (USA) LLC, as representative of the several underwriters named therein (the “Underwriting Agreement”). The Underwriting Agreement relates to the public offering of 3,000,000 shares of the Company’s common stock at a public offering price of $28.75 per share. Pursuant to the Underwriting Agreement, the Company granted the underwriters a 30-day option to purchase up to an additional 450,000 shares of the Company’s common stock at the public offering price (less the underwriting discount) solely to cover over-allotments. On July 13, 2011, the underwriters exercised the over-allotment option in full. The Company intends to use the net proceeds from this offering to repay the current outstanding balance under its secured revolving credit facility, to fund its acquisition of oil and gas assets, including in the Utica Shale in Ohio, and for general corporate purposes, which may include expenditures associated with Gulfport’s 2011 drilling programs. The offering closed on July 15, 2011.

The offering was made pursuant to the Company’s effective automatic shelf registration statement on Form S-3 (File No. 333-175435), filed with the Securities and Exchange Commission (the “SEC”) on July 11, 2011 (the “Shelf Registration Statement”), and a prospectus, which consists of a base prospectus, filed with the SEC on July 11, 2011, a preliminary prospectus supplement, filed with the SEC on July 11, 2011, and a prospectus supplement, filed with the SEC on July 12, 2011 (collectively, the “Prospectus”).

A copy of the Underwriting Agreement is filed as Exhibit 1.1 to this Current Report on Form 8-K and the contents thereof are incorporated herein by reference.

Item 7.01. Regulation FD Disclosure.

On July 12, 2011, the Company issued a press release announcing the pricing of the underwritten public offering of shares of its common stock. A copy of the press release is filed as Exhibit 99.1 to this Current Report on Form 8-K, and the contents thereof are incorporated herein by reference.
