Gulfport Energy Corporation Announces Pricing of Public Offering of Common Stock

OKLAHOMA CITY (November 30, 2011) Gulfport Energy Corporation (NASDAQ: GPOR) today announced that it has priced its previously-announced underwritten public offering of 5,000,000 shares of its common stock at a public offering price of $29.00 per share, of which 4,000,000 shares will be sold by Gulfport and 1,000,000 shares will be sold by one of its stockholders. The underwriters have an option to purchase a maximum of 600,000 additional shares from Gulfport and a maximum of 150,000 additional shares from the selling stockholder, in each case at the public offering price (less the underwriting discount) solely to cover over-allotments. Net proceeds to Gulfport from the sale of the 4,000,000 shares, after underwriting discounts and estimated expenses, will be approximately $110.9 million. Gulfport intends to use its net proceeds from this offering to repay the current outstanding balance under its secured revolving credit facility, to fund capital expenditures associated with drilling, development and infrastructure, principally in the Utica Shale in Ohio, and for general corporate purposes. Gulfport will not receive any proceeds from the sale of shares of common stock by the selling stockholder. The offering is expected to close on December 5, 2011, subject to customary closing conditions.
