Exhibit 99.2

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

On December 6, 2012, Halcón Resources Corporation (“Halcón”), pursuant to a Reorganization and Interest Purchase Agreement with Petro-Hunt, L.L.C. and Pillar Energy, LLC, acquired all of the membership interests in two newly formed limited liability companies which upon the closing of the acquisition owned 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 paid an aggregate purchase price of approximately $1.451 billion, subject to customary adjustments, consisting of $756.0 million in cash and 10,880.0993 shares of convertible preferred stock, which will automatically convert into common stock, subject to stockholder approval, with each preferred share convertible into 10,000 common shares. On November 6, 2012, Halcón sold $750 million aggregate principal amount of 8.875% senior unsecured notes due 2021 (the “8.875% Notes”), issued at 99.247% of par and the net proceeds were used to fund a portion of the cash consideration paid in the acquisition of the Williston Basin Assets.

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 were approximately $294.0 million after a $6.0 million capital commitment payment by Halcón to CPPIB upon closing of the transaction on December 6, 2012, immediately following the close of the acquisition of the Williston Basin Assets.

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. On July 16, 2012, the Company completed a private offering of $750 million aggregate principal amount of 9.75% senior unsecured notes due 2020 (the “9.75% Notes”), issued at 98.646% of par and the net proceeds were used to fund a portion of the cash consideration paid in the GeoResources Merger and the East Texas Assets acquisition.

The following unaudited pro forma condensed combined financial information and explanatory notes adjust Halcón’s historical statement of operations to give effect to the GeoResources Merger and acquisition of the East Texas Assets as of January 1, 2011 (with respect to the statements of operations information for the nine months ended September 30, 2012 and the year ended December 31, 2011). The following unaudited pro forma condensed combined financial information and explanatory notes also adjust the historical balance sheet and pro forma statement of operations of Halcón to give effect to (i) Halcón’s acquisition of the Williston Basin Assets and (ii) Halcón’s sale of approximately 41.9 million shares to CPPIB, in each case as of September 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 nine months ended September 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 acquisition of the Williston Basin Assets and the 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 Williston Basin Assets for the nine-month period ended September 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 Exhibit 99.3 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 filed with the SEC on June 25, 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 and Exhibit 99.1 to Halcón’s current report of Form 8-K filed with the SEC on December 11, 2012. The 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 adjustments to Halcón’s consolidated combined financial statements in connection with the merger and the acquisitions, and allocation of the purchase price paid in each transaction are based on a number of factors, including additional financial information available at such time, and 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.
