Exhibit 99.2

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

On October 19, 2012, Halcón Resources Corporation (“Halcón”) entered into a Reorganization and Interest Purchase Agreement with Petro-Hunt, L.L.C. and Pillar Energy, LLC, pursuant to which, subject to the conditions set forth in that agreement, Halcón will acquire all of the membership interests in two newly formed limited liability companies which upon the closing of the acquisition will own an aggregate of approximately 81,000 net acres prospective for the Bakken and Three Forks formations in North Dakota (the “Williston Basin Assets”). Pursuant to the purchase agreement, Halcón will pay an aggregate purchase price of approximately $1.45 billion, subject to customary adjustments, consisting of $700 million in cash and $750 million in shares of preferred stock, which will automatically convert into common stock at $7.45 per share, subject to stockholder approval.

On October 19, 2012, Halcón also entered into a Common Stock Purchase Agreement with a wholly owned subsidiary of the Canada Pension Plan Investment Board (“CPPIB”), pursuant to which CPPIB has agreed to purchase 41,899,441 newly issued shares of Halcón common stock at $7.16 per share for a total purchase price of approximately $300.0 million. Net proceeds to Halcón are expected to be approximately $294.0 million following an approximate $6.0 million capital commitment payment by Halcón to CPPIB upon closing of the transaction.

On August 1, 2012, Halcón completed the acquisition by merger of GeoResources, Inc. (“GeoResources”). At closing of the merger (the “GeoResources Merger”), each outstanding share of GeoResources’ common stock was converted into the right to receive $20.00 in cash and 1.932 shares of Halcón common stock. Halcón also completed the acquisition of 20,628 net acres of oil and gas leasehold in East Texas (the “East Texas Assets”) on August 3, 2012. In connection with that acquisition, Halcón issued approximately 20.8 million shares of its common stock and paid approximately $301.6 million to the sellers of the East Texas Assets.

The following unaudited pro forma condensed combined financial information and explanatory notes combine the historical financial statements of Halcón, GeoResources and the East Texas Assets as of June 30, 2012 (with respect to the balance sheet information using currently available fair value information) and as of January 1, 2011 (with respect to the statements of operations information for the six months ended June 30, 2012 and the year ended December 31, 2011). The following unaudited pro forma condensed financial information and explanatory notes also adjust the pro forma combined financial statements of Halcón, GeoResources and the East Texas Assets to give effect to (i) Halcón’s pending acquisition of the Williston Basin Assets and (ii) Halcón’s pending sale of approximately 41.9 million shares to CPPIB, in each case as of June 30, 2012 (with respect to balance sheet information using currently available fair value information) and as of January 1, 2011 (with respect to statements of operations information for the six months ended June 30, 2012 and the year ended December 31, 2011).

The unaudited pro forma condensed combined financial statements are provided for illustrative purposes only and are not intended to represent or be indicative of the consolidated results of operations or financial position of Halcón that would have been recorded had the GeoResources Merger, the East Texas Assets acquisition, the pending acquisition of the Williston Basin Assets and the pending sale of common stock to CPPIB been completed as of the dates presented and should not be taken as representative of future results of operations or financial position of Halcón. The unaudited pro forma condensed combined financial statements do not reflect the impacts of any potential operational efficiencies, asset dispositions, cost savings or economies of scale that Halcón may achieve with respect to the combined operations. Additionally, the pro forma statements of operations do not include non-recurring charges or credits and the related tax effects which result directly from the transactions. Furthermore, certain reclassifications have been made to GeoResources’ historical financial statements presented herein to conform to Halcón’s historical presentation. Additionally, the financial statements for each of the Williston Basin Assets and the East Texas Assets for the year ended December 31, 2011 and for the six-month period ended June 30, 2012 are limited to statements of revenues and direct operating expenses and therefore do not include all items of expense that would be included in full financial statements and are based on certain estimates and assumptions made by our management.

The unaudited pro forma condensed combined financial statements have been derived from and should be read in conjunction with the historical consolidated financial statements and accompanying notes contained in the Halcón Annual Report on Form 10-K and Quarterly Reports on Form 10-Q, the audited financial statements of GeoResources previously filed as Exhibits 99.3 and 99.4 to Halcón’s current report on Form 8-K/A filed with the Securities and Exchange Commission (the “SEC”) on September 11, 2012, the historical statements of revenues and direct operating expenses for the East Texas Assets previously filed as Exhibit 99.2 to Halcón’s current report on Form 8-K/A filed with the SEC on August 24, 2012, and the historical statements of revenues and direct operating expenses for the Williston Basin Assets previously filed as Exhibit 99.2 to Halcón’s current report on Form 8-K filed with the SEC on October 22, 2012 . The audited financial statements of revenues and direct operating expenses for the Williston Basin Assets and the East Texas Assets do not include all items of expense that would be included in full financial statements such as general and administrative expenses and depreciation, depletion and amortization expenses.

The assets and liabilities of GeoResources, the East Texas Assets and the Williston Basin Assets are recorded at their preliminary estimated fair values, with the excess of the purchase price over the sum of these fair values, if any, recorded as goodwill. The actual adjustments to Halcón’s consolidated combined financial statements upon consummation of the pending acquisition of the Williston Basin Assets, and allocation of the purchase price paid in that transaction will depend on a number of factors, including additional financial information available at such time, changes in the fair value of Halcón’s common stock issued at the closing date, changes in the estimated fair value of natural gas and oil properties of the

Williston Basin Assets as of the closing date, and changes in the operating results of the Williston Basin Assets between the date of preparation of this pro forma information and the effective closing date of the acquisition. Accordingly, the final allocations of transaction consideration and the effects on the results of operations may differ materially from the preliminary allocations and unaudited pro forma combined amounts included herein.
