Gastar Exploration (GST) 8-K Completion of Acquisition or Disposition of Assets

UNAUDITED PRO FORMA FINANCIAL INFORMATION

On April 19, 2013, Gastar Exploration Texas, LP (“Gastar Texas”) and Gastar Exploration USA, Inc. (“Gastar USA”), subsidiaries of Gastar Exploration Ltd. (the “Company” or “Gastar LTD” ), entered into a Purchase and Sale Agreement, dated April 19, 2013, by and among Gastar Texas, Gastar USA and Cubic Energy, Inc. (“Cubic Energy”) (as amended, the “Cubic PSA”). Pursuant to the Cubic PSA, Cubic Energy acquired from Gastar Texas approximately 31,800 gross (16,300 net) acres of leasehold interests in the Hilltop area of East Texas in Leon and Robertson Counties, Texas, including production from interests in producing wells, for a cash purchase price of approximately $47.3 million, subject to adjustment for an accounting effective date of January 1, 2013 and other customary adjustments (the “East Texas Divestiture”). The East Texas Divestiture was completed on October 2, 2013.

On March 28, 2013, Gastar USA entered into a purchase and sale agreement, by and among Chesapeake Exploration, L.L.C., Arcadia Resources, L.P., Jamestown Resources, L.L.C., Larchmont Resources, L.L.C. and Gastar USA, to acquire approximately 157,000 net acres of Mid-Continent oil and gas leasehold interests, including production from interests in 176 net producing locations in Oklahoma, for approximately $73.9 million, subject to customary adjustments (the “Chesapeake Acquisition”). The Chesapeake Acquisition had an effective date of October 1, 2012 and was completed on June 7, 2013. Subsequent to the closing of the Chesapeake Acquisition, on July 1, 2013, Gastar USA's partner in an original area of mutual interest (“AMI”) in Oklahoma elected to exercise its rights within the AMI and acquired approximately 12,820 net acres and 50% of the interest acquired in 62 producing wells (effective October 1, 2012) previously acquired by Gastar USA as part of the Chesapeake Acquisition for a cash purchase price of $12.1 million (the “AMI Election”). Also on March 28, 2013, the Company, Gastar Texas and Gastar Exploration Texas, LLC entered into a Settlement Agreement with Chesapeake Energy Corporation, L.L.C. and Chesapeake Energy Corporation and its affiliates (together, “Chesapeake”). In order to effect a mutual full and unconditional release and settlement of all claims made in a lawsuit filed by Chesapeake, Gastar USA agreed to pay Chesapeake approximately $10.8 million in cash, approximately $9.8 million of which to repurchase 6,781,768 outstanding common shares of the Company's common stock held by Chesapeake (the “Chesapeake Share Repurchase”). The Chesapeake Share Repurchase was completed on June 7, 2013. Collectively, these transactions are referred to as the “Hunton Transaction.”

On May 15, 2013, Gastar USA issued $200 million aggregate principal amount of its 8.5/8% Senior Secured Notes due 2018 under an indenture by and among Gastar USA, the Guarantors named therein, and Wells Fargo Bank, National Association, as Trustee and Collateral Agent (the “Notes Offering”). The net proceeds from the offering were used to (i) finance the Chesapeake Acquisition and the Chesapeake Share Repurchase and to settle litigation with Chesapeake, (ii) repay in full borrowings under the prior revolving credit facility and (iii) for general corporate purposes.

On July 2, 2013, Gastar USA entered into a purchase and sale agreement with Newfield Exploration Mid-Continent Inc. (“Newfield”), dated July 2, 2013, pursuant to which (i) Newfield acquired approximately 76,000 net acres of undeveloped oil and gas leasehold interests in Kingfisher and Canadian Counties, Oklahoma from Gastar USA, for a cash purchase price of approximately $60.1 million, subject to additional adjustments for an effective date of May 1, 2013 and (ii) Gastar USA acquired approximately 1,850 net acres of Oklahoma undeveloped oil and gas leasehold interests from Newfield (the “Gastar Acquired Acreage”) through a downward adjustment to the purchase price (collectively, the “Newfield Divestiture”). The Newfield Divestiture was completed on August 6, 2013.

The following unaudited pro forma financial information is derived from the historical financial statements of the Company and Gastar USA and reflects the impact of the East Texas Divestiture, the Chesapeake Acquisition, the AMI Election, the Notes Offering and use of a portion of the proceeds therefrom to fund the Chesapeake Acquisition and the Newfield Divestiture. The Unaudited Pro Forma Combined Balance Sheet of the Company as of June 30, 2013 and the Unaudited Pro Forma Combined Balance Sheet of Gastar USA as of June 30, 2013 have been prepared assuming the East Texas Divestiture, the AMI Election and the Newfield Divestiture were consummated on June 30, 2013. The impact of the Chesapeake Acquisition and the Notes Offering and use of a portion of the proceeds therefrom to fund the Chesapeake Acquisition is already reflected in the historical balance sheet financial information of the Company and Gastar USA at June 30, 2013. The Unaudited Pro Forma Combined Statements of Operations of the Company and Gastar USA for the year ended December 31, 2012 and for the six month period ended June 30, 2013 have been prepared assuming the East Texas Divestiture, the Hunton Transaction and the Notes Offering and use of a portion of the proceeds therefrom to fund the Chesapeake Acquisition were consummated on January 1, 2012. The Newfield Divestiture is a disposition of undeveloped oil and gas leasehold interests and is accounted for as an adjustment of capitalized costs, with no gain recognized as such adjustment would not significantly alter the relationship between capitalized costs and proved reserves of oil and gas attributable to the Company's or Gastar USA's full cost pool. Therefore, the Newfield Divestiture has no impact on the statement of operations.

These unaudited pro forma combined financial statements should be read in conjunction with the notes hereto and the consolidated financial statements and notes thereto included in the Annual Report on Form 10-K for the year ended December 31, 2012, as amended, and the Quarterly Report on Form 10-Q for the three and six months ended June 30, 2013, each as jointly filed by the Company and Gastar USA.

The unaudited pro forma financial information is not indicative of the financial position or results of operations of the Company or Gastar USA which would have actually occurred if the transaction had occurred at the dates presented or which may be obtained in the future. In addition, future results may vary significantly from the results reflected in such statements due to normal oil and natural gas production declines, reductions in prices paid for oil or natural gas, future acquisitions or dispositions and other factors.
