Exhibit 99.2

POSTROCK ENERGY CORPORATION
UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

     The following unaudited pro forma condensed consolidated financial statements have been prepared to assist in the analysis of PostRock Energy Corporation’s (“PostRock”) purchase of a 14.9% equity interest in Constellation Energy Partners LLC (“CEP”) from Constellation Energy Commodities Group, Inc. (“CEG”), a subsidiary of Constellation Energy Group, Inc. (the “CEP Transaction”). In the transaction, PostRock indirectly acquired 485,065 Class A Units and 3,128,670 Class B Units of CEP. The consideration paid to CEG was comprised of $6.6 million of cash, one million shares of PostRock common stock and warrants to acquire an additional 673,822 shares of PostRock common stock. Of the warrants, 224,607 are exercisable for one year at an exercise price of $6.57 a share, 224,607 are exercisable for two years at $7.07 a share and 224,608 are exercisable for three years at $7.57 a share. The cash was funded with borrowings under PostRock’s borrowing base credit facility.

     In order to present the pro forma condensed consolidated statements of operations for the year ended December 31, 2010, the pro forma condensed consolidated financial statements assume the recombination of Quest Resource Corporation (“QRCP”), Quest Energy Partners, L.P. (“QELP”) and Quest Midstream Partners, L.P. (“QMLP”) occurred on January 1, 2010. The recombination of these entities occurred on March 5, 2010 and has been accounted for as an equity transaction among the owners of a consolidated entity. Historical cost accounting has continued to be used, and no gain or loss was recognized as a result of the transaction. For additional information about the recombination, see Item 8 of PostRock’s Annual Report on Form 10-K for the year ended December 31, 2010 (the “Form 10-K”).

     The unaudited pro forma condensed consolidated statements of operations for the six months ended June 30, 2011 and the year ended December 31, 2010 assume the CEP Transaction occurred on January 1 of each period presented. The unaudited pro forma condensed consolidated balance sheet assumes the CEP Transaction occurred on June 30, 2011. The unaudited pro forma condensed consolidated financial statements are derived from the historical consolidated financial statements of PostRock and its Predecessor and are based on assumptions that management believes are reasonable in the circumstances. This information should be read together with the historical consolidated financial statements and related notes of PostRock included in the Form 10-K and its Quarterly Report on Form 10-Q for the quarter ended June 30, 2011 and of CEP attached to this Current Report on Form 8-K/A as Exhibit 99.1.

     The unaudited pro forma condensed consolidated financial information is for illustrative purposes only. The unaudited pro forma condensed consolidated financial information is not necessarily indicative of the financial results that would have occurred if the CEP Transaction had taken place on the dates indicated, nor is it indicative of the future results of PostRock.

     Because PostRock indirectly owns a 14.9% equity interest in CEP and has the right, as the indirect owner of all of the outstanding Class A Units of CEP, to appoint two of the five members of the Board of Managers of CEP, PostRock has significant influence over CEP. Accordingly, the CEP Transaction will be accounted for as an equity investment.

POSTROCK ENERGY CORPORATION
NOTES TO UNAUDITED PRO FORMA FINANCIAL STATEMENTS

Note 1 — Description of Transaction

     On August 8, 2011, PostRock Energy Corporation (“PostRock”) purchased a 14.9% equity interest in Constellation Energy Partners LLC (“CEP”) from Constellation Energy Commodities Group, Inc. (“CEG”), a subsidiary of Constellation Energy Group, Inc. (the “CEP Transaction”). In the transaction, PostRock acquired all of the outstanding equity interests in Constellation Energy Partners Management LLC, which owns (i) 485,065 Class A Units of CEP and (ii) 3,128,670 Class B Units of CEP. The consideration paid to CEG was comprised of $6.6 million of cash, one million shares of PostRock common stock and warrants to acquire an additional 673,822 shares of PostRock common stock. Of the warrants, 224,607 are exercisable for one year at an exercise price of $6.57 a share, 224,607 are exercisable for two years at $7.07 a share and 224,608 are exercisable for three years at $7.57 a share. The cash was funded with borrowings under PostRock’s borrowing base credit facility.

Note 2 — Pro Forma Adjustments

     Pro Forma Adjustments: The pro forma adjustments made to the historical consolidated financial statements of PostRock are described as follows:

     A. Reflects the fair value of the consideration paid to CEG plus estimated capitalized transaction costs associated with the transaction. Warrant valuations were based on the Black/Scholes option pricing model using the terms of the warrants. The fair value of the consideration was based on:

	i.		$6.6 million of cash consideration
	ii.		$0.4 million of estimated cash transaction expenses
	iii.		$4.1 million of stock based on 1,000,000 PostRock common shares at a closing stock price on August 8, 2011 of $4.10 per common share
	iv.		$0.5 million of warrants based on the Black-Scholes pricing model

     B. Reflects borrowings under PostRock’s borrowing base credit facility for the cash consideration and estimated transaction expenses.

     C. Reflects the increase to:

	i.		Common stock for the issuance of 1,000,000 shares of PostRock common stock $0.01 par value per share; and
	ii.		Additional-paid in capital for the issuance of shares above par value and the fair value of the warrants issued.

     D. Represents PostRock’s equity in the comprehensive loss of CEP calculated as 14.9% of CEP’s comprehensive loss for the period.

     E. Reflects the increase in interest expense associated with the $7.0 million borrowing for the cash consideration and the estimated transaction expenses. The interest calculation is based on the current year average interest rate of approximately 4.01%.

     F. Reflects the elimination of the noncontrolling interests reacquired by the consolidated entity in connection with the recombination.

     Omitted Adjustments: PostRock expects to record a nonrecurring bargain purchase gain during the 12 months following the closing of the CEP Transaction. The fair value of the consideration paid to CEG plus estimated capitalized transaction costs associated with the CEP Transaction totaled approximately $11.6 million. At June 30, 2011, 14.9% of CEP’s net book value, which is not necessarily indicative of fair value, was approximately $27.0 million. The calculation of the fair value of the assets and liabilities is ongoing and the amount of the gain is subject to change.
