Item 1.01. Entry into a Material Definitive Agreement.

On March 24, 2011, Gulfport Energy Corporation (the “Company”) entered into an Underwriting Agreement with CD Holding Company, LLC (the “Selling Stockholder”) and Credit Suisse Securities (USA) LLC and Johnson Rice & Company L.L.C., as representatives of the several underwriters named therein (the “Underwriting Agreement”). The Underwriting Agreement relates to the public offering of 4,800,000 shares of the Company’s common stock at a public offering price of $32.00 per share, of which 2,400,000 shares were offered by the Company and 2,400,000 shares were offered by the Selling Stockholder. Pursuant to the Underwriting Agreement, each of the Company and the Selling Stockholder granted the underwriters a 30-day option to purchase up to an additional 360,000 shares of the Company’s common stock at the public offering price (less the underwriting discount) solely to cover over-allotments. On March 25, 2011, the underwriters exercised the over-allotment option in full. The Company intends to use the net proceeds from the offering to fund its pending Utica Shale acquisition and for general corporate purposes, which may include expenditures associated with the Company’s 2011 drilling programs. Pending application of the net proceeds for such purposes, the Company will repay the outstanding indebtedness under its revolving credit facility. The Company will not receive any proceeds from the sale of shares of its common stock by the Selling Stockholder. The offering closed on March 30, 2011.

The offering was made pursuant to the Company’s effective shelf registration statement on Form S-3 (File No. 333-168180), filed with the Securities and Exchange Commission (the “SEC”) on July 16, 2010 and declared effective on July 28, 2010 (the “Shelf Registration Statement”), and a prospectus, which consists of a base prospectus, a preliminary prospectus supplement, filed with the SEC on March 21, 2011, and a prospectus supplement, filed with the SEC on March 28, 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 March 25, 2011, the Company issued a press release announcing the upsizing and 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.

Item 8.01. Other Events.

We are filing a legal opinion of Akin, Gump, Strauss, Hauer & Feld, L.L.P., attached as Exhibit 5.1 to this Current Report on Form 8-K, to incorporate such opinion by reference into the Shelf Registration Statement and into the Prospectus.
