POSTROCK ENERGY CORPORATION
Note 1 — Basis of Presentation
     PostRock Energy Corporation (“PostRock”) is an independent oil and gas company engaged in the acquisition, exploration, development, production and gathering of crude oil and natural gas. It manages its business in two segments, production and pipeline. Its production segment is focused in the Cherokee Basin, a 15-county region in southeastern Kansas and northeastern Oklahoma. It also has minor oil producing properties in Oklahoma and oil and gas producing properties in the Appalachia Basin. The pipeline segment consists of a 1,120 mile interstate pipeline, which transports natural gas from northern Oklahoma and western Kansas to Wichita and Kansas City.
     PostRock was formed in 2009 to combine its predecessor entities, Quest Resource Corporation, Quest Energy Partners, L.P. and Quest Midstream Partners, L.P. (collectively, the “Predecessors”) into a single company. In March 2010, it completed the recombination of these entities. Unless the context requires otherwise, references to the “Company,” “we,” “us” and “our” refer to PostRock and its subsidiaries from the date of the recombination and to the Predecessors on a consolidated basis prior thereto.
     The unaudited interim condensed consolidated financial statements have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) and reflect all adjustments that are, in the opinion of management, necessary for a fair statement of the results for the interim periods on a basis consistent with the annual audited consolidated financial statements. All such adjustments are of a normal recurring nature. Certain information, accounting policies and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been omitted pursuant to such rules and regulations, although the Company believes that the disclosures are adequate to make the information presented not misleading. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the summary of significant accounting policies and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2010 (the “2010 10-K”).
     The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The operating results for the interim periods are not necessarily indicative of the results to be expected for the full year.
Recent Accounting Pronouncements and Recently Adopted Accounting Pronouncements
     In June 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2011- 05 Comprehensive Income (Topic 220): Presentation of Comprehensive Income . ASU 2011-05 requires that all nonowner changes in stockholders’ equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In the two-statement approach, the first statement should present total net income and its components followed consecutively by a second statement that should present total other comprehensive income, the components of other comprehensive income and the total of comprehensive income. The amendments are to be applied retrospectively and are effective for fiscal years and interim periods within those years beginning after December 15, 2011. The amendment will not have a material impact on the Company’s financial statements.
     In May 2011, the FASB issued ASU 2011-04 Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs . ASU 2011-04 clarifies the principles and definitions used to measure fair value and expands disclosure requirements in order to achieve greater consistency between U.S. GAAP and International Financial Reporting Standards. The amendment does not require additional fair value measurements and is not intended to establish valuation standards or affect valuation practices outside of financial reporting. ASU 2011-04 is to be applied prospectively and is effective during interim and annual periods beginning after December 15, 2011. The amendment will not have a material impact on the Company’s financial statements.

Table of Contents

     In January 2010, the FASB issued ASU 2010-06, Fair Value Measurements and Disclosures (Topic 820): Improving Disclosures about Fair Value Measurements. The update requires reporting entities to provide information about movements of assets among Levels 1 and 2 of the three-tier fair value hierarchy established under FASB Accounting Standards Codification (“ASC”) 820. The update also requires separate presentation (on a gross basis rather than as one net number) about purchases, sales, issuances, and settlements within the reconciliation of activity in Level 3 fair value measurements. The guidance is effective for any fiscal period beginning after December 15, 2009, except for the requirement to separately disclose purchases, sales, issuances, and settlements, which is effective for any fiscal period beginning after December 15, 2010. The Company adopted the provisions of this update relating to disclosure on movement of assets among Levels 1 and 2 beginning with the quarter ended March 31, 2010, while the provisions requiring gross presentation of activity within Level 3 assets were adopted beginning with the quarter ended March 31, 2011. The adoption did not materially affect the Company’s financial statements.
Note 2 — Acquisitions and Divestitures
      Constellation Energy Partners LLC (“CEP”) investment — On August 8, 2011, the Company acquired, from Constellation Energy Group, Inc. (“CEG”), a 14.9% voting interest in CEP and the right to appoint two directors to CEP’s Board. The total cost of the investment was $11.5 million, including $6.6 million of cash, 1,000,000 shares of PostRock common stock with a fair value of $4.1 million and warrants to acquire an additional 673,822 shares of PostRock common stock with a fair value of $518,000, and acquisition costs of $283,000. Of the warrants, 224,607 are exercisable for one year following issuance at an exercise price of $6.57 a share, 224,607 are exercisable for two years following issuance at $7.07 a share and 224,608 for three years following issuance at $7.57 a share. The 14.9% voting interest consisted of 485,065 of CEP’s outstanding Class A Member Interests, representing all of the class, and 3,128,670 Class B Member Interests, representing 13.2% of the class at the time.
     CEP is focused on the acquisition, development and production of oil and natural gas properties as well as related midstream assets. All of its proved reserves are located in the Cherokee Basin in Kansas and Oklahoma, the Black Warrior Basin in Alabama, the Woodford Shale in the Arkoma Basin in Oklahoma and the Central Kansas Uplift in Kansas and Nebraska. Because the Company and CEP each have the majority of their assets in the Cherokee Basin of Kansas and Oklahoma, the investment was made in an attempt to increase the likelihood of improved efficiencies in this region through cooperation with CEP and others.
      Appalachia Basin Sale — On December 24, 2010, the Company entered into an agreement with Magnum Hunter Resources Corporation (“MHR”) to sell certain oil and gas properties and related assets in West Virginia. The sale closed in three phases for a total of $44.6 million. The first phase closed on December 30, 2010, for $28 million, the second phase closed on January 14, 2011, for $11.7 million and the third phase closed on June 16, 2011, for $4.9 million. The amount received for the first and second phases was paid half in cash and half in MHR common stock, while the amount received for the third phase was paid entirely in cash.
     Of the proceeds received, $6.4 million was set aside in escrow to cover potential claims for indemnity and title defects. The total first and second closing escrowed amount of $5.9 million is to be released in June 2012 and is reflected in the condensed consolidated balance sheet as a component of other current assets. The third closing escrowed amount of $564,000 is to be released in December 2012 and is reflected in the condensed consolidated balance sheet as a component of other noncurrent assets. If all of the amounts in escrow are released, the Company would receive a total of $1.5 million, which includes $843,000 in connection with the QER Loan (see Note 7 - Long-Term Debt). The remaining amount would be released to RBC and a third-party and is reflected in the condensed consolidated balance sheet in other current and non-current liabilities.
     In general, no gains or losses are recognized upon the sale or disposition of oil and gas properties unless the deferral of gains or losses would significantly alter the relationship between capitalized costs and proved reserves of oil and gas. A significant alteration generally occurs when the deferral of gains or losses will result in an amortization rate materially different from the amortization rate calculated upon recognition of gains or losses. The Company’s evaluation demonstrated that a material difference in amortization rates would occur if no gain was recognized on the three-phased sale described above. Gains of $9.9 million and $2.5 million, net of $225,000 and $2.4 million in selling costs and adjustments, were recorded in January 2011 and June 2011 related to the second and third phases of the sale. The corresponding reduction in the Company’s oil and gas full cost pool was $1.5 million for the second closing with no reduction for the third closing.

Note 3 — Derivative Financial Instruments
     The Company is exposed to commodity price risk and management believes it prudent to periodically reduce exposure to cash-flow variability resulting from this volatility. Accordingly, the Company enters into certain derivative financial instruments in order to manage exposure to commodity price risk inherent in its oil and gas production. Derivative financial instruments are also used to manage commodity price risk inherent in customer pricing requirements and to fix margins on the future sale of natural gas. Specifically, the Company may utilize futures, swaps and options.
     Derivative instruments expose the Company to counterparty credit risk. The Company’s commodity derivative instruments are currently with several counterparties. The Company generally executes commodity derivative instruments under master agreements which allow it, in the event of default, to elect early termination of all contracts with the defaulting counterparty. If the Company chooses to elect early termination, all asset and liability positions with the defaulting counterparty would be net cash settled at the time of election.
     The Company monitors the creditworthiness of its counterparties; however, it is not able to predict sudden changes in counterparties’ creditworthiness. In addition, even if such changes are not sudden, it may be limited in its ability to mitigate an increase in counterparty credit risk. Possible actions would be to transfer its position to another counterparty or request a voluntary termination of the derivative contracts resulting in a cash settlement. Should one of these counterparties not perform, the Company may not realize the benefit of some of its derivative instruments under lower commodity prices as well as incur a loss. The Company includes a measure of counterparty credit risk in its estimates of the fair values of derivative instruments in an asset position.
     The Company does not designate its derivative financial instruments as hedging instruments for financial accounting purposes; as a result, it recognizes the change in the respective instruments’ fair value currently in earnings. The table below outlines the classification of derivative financial instruments on the condensed consolidated balance sheet and their financial impact on the condensed consolidated statements of operations at and for the periods indicated (in thousands):

Note 4 — Fair Value Measurements
     Certain assets and liabilities are measured at fair value on a recurring basis in the Company’s condensed consolidated balance sheets. The following methods and assumptions were used to estimate the fair values:
      Cash and Equivalents, Accounts Receivable and Accounts Payable The carrying amounts approximate fair value due to the short-term nature or maturity of the instruments.
      Commodity Derivative Instruments The Company’s oil and gas derivative instruments may consist of variable to fixed price swaps, collars and basis swaps. When possible, the Company estimates the fair values of these instruments based on published forward commodity price curves as of the date of the estimate. The discount rate used in the discounted cash flow projections is based on published LIBOR rates adjusted for counterparty credit risk. Counterparty credit risk is incorporated into derivative assets while the Company’s own credit risk is incorporated into derivative liabilities. Both are based on the current published credit default swap rates. See Note 3 — Derivative Instruments and Hedging Activities.
      Short-Term Investments Short term investments are included in other current assets in the condensed consolidated balance sheet. At December 31, 2010, these investments consisted of 218,095 shares of MHR common stock received as proceeds from the Appalachia Basin sale described in Note 2, which were subsequently sold in June 2011 for $1.5 million.

      Investment in Affiliate The Company’s 14.9% voting interest in CEP consists of 485,065 of CEP’s outstanding Class A Member Interests and 3,128,670 Class B Member Interests. Fair value for the Class B Member Interests which are publicly traded is based on market price. Fair value for the Class A Member Interests is based on the market price of the publicly traded interests and a premium reflecting certain additional rights. At September 30, 2011, the fair value used for the Class A units and the Class B units was $4.07 and $2.78 per unit, respectively.

Level 1 — Quoted prices available in active markets for identical assets or liabilities at the reporting date.
Level 2 — Pricing inputs other than quoted prices in active markets included in Level 1 which are either directly or indirectly observable at the reporting date. Level 2 consists primarily of non-exchange traded commodity derivatives.
Level 3 — Pricing inputs include significant inputs that are generally less observable from objective sources.
     The Company classifies assets and liabilities within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement of each individual asset and liability taken as a whole.
     In June 2011, the Company transferred 23,517 shares of MHR common stock with a fair value of $159,000 from Level 2 to Level 1 due to the limited amount of time remaining until restrictions on the Company’s ability to trade these securities lapsed in July 2011. The lifting of restrictions enabled the Company to value these securities at published market prices. Following the lapse of restrictions, these securities were sold in July 2011 for approximately $168,000. There were no other movements between Levels 1 and 2 during the periods from January 1 to March 5 and March 6 to September 30, 2010, and for the nine months ended September 30, 2011.
     The following table sets forth a reconciliation of changes in the fair value of risk management assets and liabilities classified as Level 3 in the fair value hierarchy for the periods presented (in thousands).

      Additional Fair Value Disclosures — The Company has 6,000 outstanding shares of Series A Cumulative Redeemable Preferred Stock (see Note 8 — Redeemable Preferred Stock and Warrants). The fair value and the carrying value of these securities were $68.5 million and $50.6 million, respectively, at December 31, 2010, and $51.0 million and $55.1 million, respectively, at September 30, 2011. The fair value was determined by discounting

the cash flows over the remaining life of the securities utilizing a LIBOR interest rate and a risk premium which was based on companies with similar leverage ratios to PostRock.
     The Company’s long-term debt consists entirely of floating-rate facilities. The carrying amount of floating-rate debt approximates fair value because the interest rates paid on such debt are generally set for periods of six months or shorter.
Note 5 —Investment in Affiliate
     The Company believes that its 14.9% voting interest in CEP along with the right to appoint two directors to CEP’s Board provide it the ability to exercise significant influence over the operating and financial policies of CEP. Rather than accounting for the investment under the equity method, the Company elected the fair value option to account for its interest in CEP at the acquisition date on August 8, 2011. The fair value option was chosen as the Company determined that the market price of CEP’s publicly traded interests provided a more accurate fair value measure of the Company’s investment in CEP. As a result of the decline in the market price of CEP’s traded interests, the Company recorded a loss of $0.9 million during the three month and nine month periods ending September 30, 2011. The loss was recorded as a component of other income (expense) in the condensed consolidated statement of operations.

     As discussed in Note 2, the Company sold certain Appalachia Basin oil and gas properties to MHR in three phases that closed in December 2010, January 2011 and June 2011. The $44.6 million aggregate purchase price for the three phases was received in cash and in shares of MHR stock. Included in the $44.6 million total was approximately $41.6 million representing the purchase price of assets owned by one of the Company’s subsidiaries, PostRock Eastern Production, LLC, formerly named Quest Eastern Resource LLC (“QER”), pledged as collateral under the QER Loan. From the sale proceeds, QER made payments to the lender, Royal Bank of Canada (“RBC”), in the amount of $21.2 million in December 2010, $9.3 million in January 2011 and $4.3 million in June 2011. The $9.3 million payment in January 2011 consisted of $5.7 million in MHR common stock and $3.6 million in cash while the $4.3 million payment in June 2011 was entirely in cash. Concurrent with the June 2011 payment and pursuant to the terms of an asset sale agreement with RBC, the Company fully settled the outstanding balance of the QER Loan of approximately $843,000 by issuing 141,186 shares of its common stock with a fair value of $744,000 to RBC. The Company expects to recover the full amount of the $843,000 payment to RBC in June 2012.
     The settlement of the QER Loan was facilitated by the restructuring of a prior loan (the “PESC Loan”) that met the criteria under accounting guidance to be classified as a troubled debt restructuring. The Company had previously recorded a gain on troubled debt restructuring related to the QER Loan of $2.9 million in 2010. Following a re-evaluation of the maximum sum of future cash flows that would be paid to RBC, the Company recorded an additional gain of $1.6 million during the second quarter of 2011. The gain includes $799,000 of accrued interest that was forgiven at the time the balance of the loan was settled. The gain is reflected as a “gain on forgiveness of debt” in the condensed consolidated statement of operations.

     The borrowing base under the Borrowing Base Facility was redetermined effective July 31, 2011, based on the Company’s oil and gas reserves at March 31, 2011. The borrowing base is determined based on the value of reserves at the Company’s lenders’ forward price forecasts, which are generally derived from futures prices. As a result of the significant decline in lender forward price forecasts since the Company’s prior borrowing base determination and the roll off of hedges, the borrowing base was reduced from $225 million to $200 million.
     The Company made periodic payments of $7.5 million on the Secured Pipeline Loan and net borrowings of $3.0 million on the Borrowing Base Facility during the nine month period ended September 30, 2011. The Company was in compliance with all its financial covenants at September 30, 2011.
Note 8 — Redeemable Preferred Stock and Warrants
     Prior to July 1, 2013, the Company may accrue dividends on its Series A Preferred Stock rather than paying them in cash. Whenever dividends are accrued on a quarterly dividend payment date, the liquidation preference of the Series A Preferred Stock is increased by the amount of the accrued dividends and additional warrants to purchase shares of PostRock common stock and additional shares of Series B Preferred Stock are issued. The Company records the increase in liquidation preference and the issuance of additional warrants by allocating their relative fair values to the amount of accrued dividends. The allocation results in an increase to the Company’s temporary equity related to the Series A Preferred Stock and an increase to additional paid in capital related to the additional warrants issued. The increase to additional paid in capital related to additional warrants issued was $745,000, $752,000 and $921,000 in the first, second and third quarters of 2011, respectively.
     The following tables describe the changes in temporary equity, currently comprised of the Series A Preferred Stock (in thousands except share amounts), and in outstanding warrants:

Note 9 — Equity and Earnings per Share
      Share-Based Payments — The Company recorded share based compensation expense of $354,000 and a credit of $157,000 for the three months ended September 30, 2010 and 2011, respectively. The credit for the three months ended September 30, 2011 was a result of forfeitures due to employee turnover. Expense for the periods from January 1 to March 5 and March 6 to September 30, 2010, was $808,000 and $987,000, respectively, and $1.2 million for the nine months ended September 30, 2011. Total share-based compensation to be recognized on unvested stock awards and options at September 30, 2011, is $792,000 over a weighted average period of 1.32 years. The following table summarizes option awards granted during 2011 and their associated valuation assumptions:

Note 10 — Commitments and Contingencies
      Litigation — The Company is subject, from time to time, to certain legal proceedings and claims in the ordinary course of conducting its business. It records a liability related to its legal proceedings and claims when it has determined that it is probable that it will be obligated to pay and the related amount can reasonably be estimated. Except for those legal proceedings listed below, it believes there are no pending legal proceedings in which it is currently involved that, if adversely determined, would have a material adverse effect on its financial position, results of operations or cash flows.
     As further described in Note 14 of Part II, Item 8 in the 2010 10-K, the Company had been sued in royalty owner lawsuits filed in Oklahoma and Kansas.
     In Oklahoma, suits by a group of individual royalty owners and by a putative class representing all remaining royalty owners were filed in the District Court of Nowata County, Oklahoma. Generally, the lawsuits alleged that the Company wrongfully deducted post-production costs from the plaintiffs’ royalties and engaged in self-dealing contracts and agreements resulting in a less than market price for the gas production. The Company denied the allegations. Settlements have been reached in each of the cases, and on July 28, 2011, the Court entered a final order approving the class action settlement. The Company funded the $5.6 million in settlements on July 29, 2011.
     The Kansas lawsuit is a putative class action filed in the United States District Court for the District of Kansas, brought on behalf of all the Company’s royalty owners in that state. Plaintiffs generally allege that the Company failed to properly make royalty payments by, among other things, charging post-production costs to royalty owners in violation of the underlying lease contracts, paying royalties based on sale point volumes rather than wellhead volumes, allocating expenses in excess of the actual and reasonable post-production costs incurred, allocating production costs and marketing costs to royalty owners, and making royalty payments after the statutorily prescribed time for doing so without paying interest thereon. The parties have reached a settlement in this class action which is subject to approval by the Court. The settlement includes a payment of $3.0 million to be made within 30 days after final approval by the Court and a payment of $4.5 million one year thereafter.
     At September 30, 2011, the Company had reserved $7.0 million for the estimated cost to resolve the Kansas action. The $7.0 million includes $3.0 million expected to be paid in January 2012 and $4.0 million representing the present value of an additional $4.5 million expected to be paid one year thereafter. The $4.0 million reserve is reflected in other noncurrent liabilities in the condensed consolidated balance sheet. Increases to the reserve for both the Oklahoma and Kansas royalty owner lawsuits included $9.5 million, $100,000 and $2.0 million added in the first, second and third quarters of 2011, respectively.
      Contractual Commitments — The Company has numerous contractual commitments in the ordinary course of business, debt service requirements and operating lease commitments. During the first quarter of 2011, the Company entered into new operating leases for compressors utilized in its gathering system. The leases convert already utilized compressors from month-to-month to a specified term lease. As a result, the $900,000 minimum amount of these contracts would be an increase to the amount included in the Company’s outstanding commitments table at December 31, 2010. The Company also extended the term of a leased facility in Olathe, Kansas, in August 2011 for an additional five years to December 2016, for a total commitment of $335,000.
     Other than the compressor leases, lease extension and debt repayments during the nine months ended September 30, 2011, there were no material changes to the Company’s commitments since December 31, 2010.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
Overview
     PostRock Energy Corporation (“PostRock”) is an independent oil and gas company engaged in the acquisition, exploration, development, production and gathering of crude oil and natural gas. We manage our business in two segments, production and pipeline. Our production segment is focused in the Cherokee Basin, a 15-county region in southeastern Kansas and northeastern Oklahoma. We also have minor oil producing properties in Oklahoma and gas producing properties in the Appalachia Basin. Our pipeline segment consists of a 1,120 mile interstate natural gas pipeline, which transports natural gas from northern Oklahoma and western Kansas to Wichita and Kansas City.
     The following discussion should be read together with the unaudited consolidated financial statements and related notes included elsewhere herein and with our annual report on Form 10-K for the year ended December 31, 2010.
     Our highlights during the first nine months of 2011 include:
    Acquired a 14.9% voting interest in Constellation Energy Partners, LLC (“CEP”).
    Closed on the second and third phases of our Appalachia Basin sale for $11.7 million and $4.9 million, respectively.
    Reduced debt by $24.2 million from December 31, 2010, including the full settlement of our QER Loan.
    Settled all of our Oklahoma royalty interest owner lawsuits for $5.6 million which was funded in July 2011 and reached a preliminary settlement of our Kansas royalty owner class action lawsuit for $7.5 million.
    Brought 93 new oil and gas wells online in the Cherokee Basin, 10 of which were drilled prior to 2011. Recompleted 83 wells and returned 53 wells in the Basin to production.
2011 Drilling and Development Update
     We budgeted $43.6 million for drilling and development in 2011. During the first three quarters of 2011, we drilled and connected 83 development wells, completed 10 new wells drilled in prior periods, recompleted or connected 83 wells and returned 53 wells to production in the Cherokee Basin. We have spent $20.6 million for drilling and development through September 30, 2011, compared to $35.8 million budgeted. During the fourth quarter, we expect to drill, complete, and connect approximately 15 wells, primarily to retain acreage. Our decision to spend less on development activity is due to the decline in gas prices and the even greater need to better understand results of our drilling activity. We are focused on improving rates of return on our development activity by reducing expenses while improving performance of newly drilled wells and recompletions.
CEP Investment
     On August 8, 2011, we acquired, from Constellation Energy Group, Inc. (“CEG”), a 14.9% voting interest in CEP and the right to appoint two directors to CEP’s Board. The total cost of the investment was $11.5 million, including $6.6 million of cash, 1,000,000 shares of our common stock with a fair value of $4.1 million and warrants to acquire an additional 673,822 shares of our common stock with a fair value of $518,000, and acquisition costs of $283,000. Of the warrants, 224,607 are exercisable for one year following issuance at an exercise price of $6.57 a share, 224,607 are exercisable for two years following issuance at $7.07 a share and 224,608 for three years following issuance at $7.57 a share. The 14.9% voting interest consisted of 485,065 of CEP’s outstanding Class A Member Interests, representing all of the class, and 3,128,670 Class B Member Interests, representing 13.2% of the class at the time. The Class B Member Interests are traded on the New York Stock Exchange under the ticker “CEP” with a closing price of $2.78 per unit at September 30, 2011.
     CEP is focused on the acquisition, development and production of oil and natural gas properties as well as related midstream assets. All of its proved reserves are located in the Cherokee Basin in Kansas and Oklahoma, the Black Warrior Basin in Alabama, the Woodford Shale in the Arkoma Basin in Oklahoma and the Central Kansas

Uplift in Kansas and Nebraska. Because we and CEP each have the majority of their assets in the Cherokee Basin of Kansas and Oklahoma, the investment was made in an attempt to increase the likelihood of improved efficiencies in this region through cooperation with CEP and others.

     We account for our investment in CEP at fair value and recognize the change in fair value in our results of operations.
Results of Operations
     In March 2010, PostRock completed the recombination of its three predecessor entities. The results of operations for the nine months ended September 30, 2010, represent the combined results of these predecessor entities and PostRock. The results of operations for all other periods presented are those of PostRock. Unless the context requires otherwise, references to the “Company,” “we,” “us” and “our” refer to PostRock and its subsidiaries from the date of the recombination and to the three predecessor entities on a consolidated basis prior thereto.

     Oil and gas sales decreased $941,000, or 4.4%, from $21.4 million during the three months ended September 30, 2010, to $20.5 million during the three months ended September 30, 2011. Lower production volumes resulted in a $990,000 decrease, partially offset by higher realized natural gas equivalent prices, which resulted in a $49,000 increase. Production decreased due to the divestiture of the Appalachia Basin assets and reduced production volumes in the Cherokee Basin. The Cherokee Basin reduction is due to lower than planned development activity, as discussed earlier, and natural production declines. Production related to divested Appalachian assets was 52 Mmcfe or 0.6 Mmcfe/d in the prior year period. Driven by higher realized oil prices, our average realized natural gas equivalent prices increased from $4.34 per Mcfe for the three months ended September 30, 2010, to $4.35 per Mcfe for the three months ended September 30, 2011.
     Gathering revenue decreased $54,000, or 3.8%, from $1.44 million for the three months ended September 30, 2010, to $1.38 million for the three months ended September 30, 2011, primarily due to a decline in transported volumes. We expect gathering revenue to decrease substantially following resolution of our Kansas royalty owner litigation.
     Pipeline revenue increased $99,000, or 4.1%, from $2.4 million for the three months ended September 30, 2010, to $2.5 million for the three months ended September 30, 2011. The increase was primarily due to increased volumes transported on the system and higher commodity revenue.
     Production expense consists of lease operating expenses, severance and ad valorem taxes (collectively, “production taxes”) and gathering expense. Production expense increased $941,000, or 8.6%, from $10.9 million for the three months ended September 30, 2010, to $11.8 million for the three months ended September 30, 2011. Production taxes increased $1.1 million from $649,000 for the three months ended September 30, 2010, to $1.8 million for the three months ended September 30, 2011. Production taxes were lower in the prior year quarter as ad valorem taxes were revised to reflect lower reserve values assessed by taxing authorities in 2010. The increase in production taxes was offset by a decrease in lease operating expenses. Lease operating expenses decreased $196,000 from $10.3 million for the three months ended September 30, 2010 to $10.1 million for the three months ended September 30, 2011. Excluding production taxes, production expense was $2.07 per Mcfe for the three months ended September 30, 2010, as compared to $2.13 per Mcfe for the three months ended September 30, 2011. There are several projects underway to reduce expenses and improve performance on wells, which is expected to have a positive impact on our cost per Mcfe.

     Pipeline expense decreased $299,000, or 20.9%, from $1.4 million during the three months ended September 30, 2010, to $1.1 million during the three months ended September 30, 2011. The decrease was primarily due to a significant reduction in costs related to our December 2010 partial termination of a capacity lease. The capacity lease subsequently expired at the end of October 2011.
     Depreciation, depletion and amortization increased $1.9 million, or 38.6%, from $4.9 million during the three months ended September 30, 2010, to $6.8 million during the three months ended September 30, 2011. This increase is the result of including the gathering system in our full cost pool beginning in the fourth quarter of 2010 which accelerated the gathering system’s depletion under the units of production method. The gathering system was previously a component of our pipeline segment and depreciated under the straight line method.
     Litigation reserve was $20,000 for the three months ended September 30, 2010, and $2.0 million for the three months ended September 30, 2011. The expense in 2011 was related to our Kansas royalty owner lawsuit. A settlement was reached for our Kansas royalty owner litigation in September 2011. Under the terms of the settlement, we will pay claimants a total of $7.5 million. An initial $3.0 million payment is required within 30 days after final court approval is granted, which is currently anticipated in December 2011. The remaining payment of $4.5 million will be due one year thereafter. Our reserve for the litigation reflects the present value of both payments of approximately $7.0 million.
     Recovery of misappropriated funds was $1.0 million for the three months ended September 30, 2010. The amount represents recovery of a portion of funds misappropriated between 2005 and 2007 by former officers, as more fully described in our Annual Report on Form 10-K for the year ended December 31, 2010.
     General and administrative expenses decreased $397,000, or 8.6%, from $4.6 million during the three months ended September 30, 2010, to $4.2 million during the three months ended September 30, 2011. The decrease was primarily due to lower legal and board fees following our September 2010 refinancing, partially offset by $757,000 of office closure costs recorded during the period upon securing a sublease for our Houston office which was previously consolidated with our Oklahoma City office.
     Other income was $23.7 million during the three months ended September 30, 2010, compared to $25.7 million during the three months ended September 30, 2011. Gain from derivative financial instruments was $32.3 million during the three months ended September 30, 2010, compared to $12.0 million during the three months ended September 30, 2011. We recorded a $25.5 million unrealized gain and $6.8 million realized gain on our derivative contracts for the three months ended September 30, 2010, compared to a $4.7 million unrealized gain and $7.3 million realized gain for the three months ended September 30, 2011. Interest expense, net, was $8.6 million during the three months ended September 30, 2010, and $2.6 million during the three months ended September 30, 2011. The decrease is primarily due to the September 2010 refinancing which resulted in a lower balance of debt, lower interest rates and decreased amortization of debt issuance costs. The loss from investment in affiliate was $859,000 during the three months ended September 30, 2011, which was due to a decline in the fair value of our investment in CEP.

     Oil and gas sales decreased $6.4 million, or 9.4%, from $68.7 million during the nine months ended September 30, 2010, to $62.3 million during the nine months ended September 30, 2011. Lower production volumes resulted in a $2.6 million decrease and lower realized natural gas equivalent prices resulted in a $3.8 million decrease. Production decreased due to the divestiture of the Appalachia Basin assets and reduced production volumes in the Cherokee Basin. Production related to divested Appalachian assets was 190 Mmcfe or 0.7 Mmcfe/d in the prior year period. The Cherokee Basin reduction is due to lower than planned development activity, as discussed earlier, and natural production declines. Our average realized natural gas equivalent prices decreased from $4.68 per Mcfe for the nine months ended September 30, 2010, to $4.41 per Mcfe for the nine months ended September 30, 2011 as lower realized natural gas prices more than offset higher realized oil prices.
     Gathering revenue decreased $145,000, or 3.3%, from $4.4 million for the nine months ended September 30, 2010, to $4.3 million for the nine months ended September 30, 2011, primarily due to a decline in transported volumes. We expect gathering revenue to decrease substantially following resolution of our Kansas royalty owner litigation.
     Pipeline revenue increased $830,000, or 11.4%, from $7.3 million for the nine months ended September 30, 2010, to $8.1 million for the nine months ended September 30, 2011. The increase was primarily due to increased volumes transported on the system and higher commodity revenue.
     Production expense was flat at $35.7 million for the nine months ended September 30, 2010 and 2011. An increase in lease operating expenses of approximately $500,000 was offset by a decrease in production taxes of the same magnitude. The increase in lease operating expense was primarily due to higher oil well workover costs. Production expense was $2.43 per Mcfe for the nine months ended September 30, 2010, as compared to $2.52 per Mcfe for the nine months ended September 30, 2011.
     Pipeline expense decreased $694,000, or 14.3%, from $4.8 million during the nine months ended September 30, 2010, to $4.1 million during the nine months ended September 30, 2011. The decrease was primarily due to a significant reduction in costs related to our December of 2010 partial termination of a capacity lease that was partially offset by the costs associated with gas lost in the first quarter of 2011 due to an external corrosion leak.

     Depreciation, depletion and amortization increased $5.4 million, or 36.1%, from $15.0 million during the nine months ended September 30, 2010, to $20.5 million during the nine months ended September 30, 2011. As noted above, beginning in the fourth quarter of 2010, the gathering system was included in our full cost pool and depreciated under the units of production method. This change drove an increase in depletion and amortization of approximately $5.3 million. Depreciation and amortization expense on our pipeline segment increased $118,000, or 4.6%, from $2.6 million during the nine months ended September 30, 2010, to $2.7 million during the nine months ended September 30, 2011.
     Gain from the sale of assets of $12.4 million during the nine months ended September 30, 2011, was primarily due to the second and third phases of the Appalachia Basin sale in 2011. Gross proceeds from both phases were $16.6 million.
     General and administrative expenses decreased $5.6 million, or 28.1%, from $19.9 million during the nine months ended September 30, 2010, to $14.3 million during the nine months ended September 30, 2011. Our March 2010 recombination and the September 2010 refinancing have enabled us to eliminate significant overhead costs. Partially offsetting the decrease are the Houston office closure costs discussed above.
     Litigation reserve increased $9.9 million, from $1.7 million during the nine months ended September 30, 2010, to $11.6 million during the nine months ended September 30, 2011. The $1.7 million expense for the nine months ended September 30, 2010, was primarily related to shareholder related lawsuits that were settled in early 2011. The $11.6 million expense for the nine months ended September 30, 2011, was for an increase to the estimated potential cost to resolve royalty owner lawsuits pending in Oklahoma and Kansas. These represent the last known significant contingent liabilities remaining from our predecessor entities. All of our Oklahoma royalty owner lawsuits were settled and funded in July 2011 for $5.6 million. The settlement of our Kansas royalty owner lawsuit will require a $3.0 million payment within 30 days after final Court approval is granted and a $4.5 million payment one year thereafter. The present value of both payments is estimated to be $7.0 million. The expense recorded in 2011 for this lawsuit established the $5.6 million reserve for the Oklahoma lawsuit and increased the reserve for the Kansas lawsuit to $7.0 million at September 30, 2011.
     Recovery of misappropriated funds was $1.0 million for the nine months ended September 30, 2010. The amount represents recovery of a portion of funds misappropriated between 2005 and 2007 by former officer.
     Other income was $53.1 million during the nine months ended September 30, 2010, compared to $27.0 million during the nine months ended September 30, 2011. Gain from derivative financial instruments was $75.5 million during the nine months ended September 30, 2010, compared to $16.7 million during the nine months ended September 30, 2011. We recorded a $54.4 million unrealized gain and $21.1 million realized gain on our derivative contracts for the nine months ended September 30, 2010, compared to a $6.5 million unrealized loss and $23.2 million realized gain for the nine months ended September 30, 2011. Interest expense, net, was $22.4 million during the nine months ended September 30, 2010, and $7.9 million during the nine months ended September 30, 2011. The decrease is primarily due to the September 2010 refinancing, which resulted in lower debt balances, lower interest rates and decreased amortization of debt issuance costs. Gain from forgiveness of debt was $1.6 million during the nine months ended September 30, 2011. The gain was a result of the settlement of our QER Loan under a troubled debt restructuring as discussed in Liquidity and Capital Resources — QER Loan below. The loss from investment in affiliate was $859,000 during the nine months ended September 30, 2011, which was due to a decline in the fair value of our investment in CEP.

Liquidity and Capital Resources
     Cash flows from operating activities have historically been driven by the quantities of our production, the prices received from the sale of this production, and from our pipeline revenue. Prices of oil and gas have historically been very volatile and can significantly impact the cash from the sale our production. Use of derivative financial instruments help mitigate this price volatility. Cash expenses also impact our operating cash flow and consist primarily of production operating costs, production taxes, interest on our indebtedness and general and administrative expenses.
     Our primary sources of liquidity for the nine months ended September 30, 2011, were cash generated from our operations and commodity derivatives, cash from the sale of oil and gas properties and available borrowings under our credit facility. At September 30, 2011, we had $8.4 million of availability under the facility, which included $1.6 million in outstanding letters of credit. On October 31, 2011, we had $9.9 million of availability under the facility.
      Cash Flows from Operating Activities
     Cash flows provided by operating activities decreased $5.8 million from $35.3 million for the nine months ended September 30, 2010, to $29.5 million for the nine months ended September 30, 2011. The decrease was primarily due to a decline in revenues which was only partially offset by our commodity derivative instruments.
      Cash Flows from Investing Activities
     Cash flows used in investing activities were $22.4 million for the nine months ended September 30, 2010, compared to $17.9 million for the nine months ended September 30, 2011. Capital expenditures were $22.9 million and $23.4 million for the nine months ended September 30, 2010 and 2011, respectively. Our purchase of a 14.9% voting interest in CEP in 2011 included $6.9 million in cash for consideration paid to the seller and for transaction fees. Cash proceeds from the second and third phases of our Appalachia Basin sale in 2011 were $10.7 million. Proceeds from the sale of equity securities received from the Appalachia Basin sale were $1.6 million. The following table sets forth our capital expenditures, including costs we have incurred but not paid, by major categories for the nine months ended September 30, 2011 (in thousands):

      Cash Flows from Financing Activities
     Cash flows used in financing activities were $32.5 million for the nine months ended September 30, 2010, as compared to $12.3 million for the nine months ended September 30, 2011. During the nine months ended September 30, 2010, proceeds from the issuance of preferred stock and warrants were $60.0 million and $2.1 million was from debt. These proceeds were offset by $89.0 million in debt repayments and $6.5 million in financing fees. During the nine months ended September 30, 2011, proceeds from debt were $3.0 million and from stock option exercises were $66,000. These proceeds were offset by $15.3 million in debt repayments.

Sources of Liquidity in 2011 and Capital Requirements
     As discussed above, at October 31, 2011, we had $9.9 million of availability under our borrowing base credit facility, which we utilize as an external source of long and short term liquidity. In addition, $30 million of capital may also be available from White Deer Energy, L.P. (“White Deer”) to March 2012 for acquisitions, an accelerated development program or other corporate purposes on mutually acceptable terms pursuant to our securities purchase agreement with White Deer.
     The borrowing base under our borrowing base credit facility was redetermined effective July 31, 2011, based on reserves at March 31, 2011. The borrowing base under that facility is determined based on the value of our oil and natural gas reserves at our lenders’ forward price forecasts, which are generally derived from futures prices. As a result of the significant decline in lender forward price forecasts since our borrowing base was last determined and the roll off of hedges, our borrowing base was reduced from $225 million to $200 million. The next borrowing base redetermination, based on reserves at December 31, 2011, is expected to be effective as of April 30, 2012.
     We have an effective $100 million universal shelf registration statement on Form S-3. We are initially limited to selling debt or equity securities under the shelf registration statement in one or more offerings over a 12 consecutive month period for a total initial public offering price not exceeding one third of our public equity float. The registration statement is intended to give us the flexibility to sell securities if and when market conditions and circumstances warrant, to provide funding for growth or other strategic initiatives, for debt reduction or refinancing and for other general corporate purposes. The actual amount and type of securities or combination of securities and the terms of those securities will be determined at the time of sale, if such sale occurs. If and when a particular series of securities is offered, the prospectus supplement relating to that offering will set forth our intended use of the net proceeds. In addition, we have entered into an at-the-market issuance sales agreement with a sales agent relating to the offering from time to time of shares of our common stock under the shelf registration statement. Sales of shares of our common stock, if any, may be made directly on the NASDAQ Global Market, on any other existing trading market for the common stock or through a market maker, or in privately negotiated transactions, subject to our approval. Our sales agreement is limited to the sale of up to a number of shares of common stock with an initial offering price not to exceed the amount that can be sold under the registration statement. As of the date of the sales agreement, such amount is limited to approximately $20.3 million. As of September 30, 2011, we had not issued any shares of common stock pursuant to the sales agreement.
Appalachia Basin Sale
     On December 24, 2010, we entered into an agreement with Magnum Hunter Resources Corporation (“MHR”) to sell to MHR certain oil and gas properties and related assets in West Virginia. The sale closed in three phases for a total of $44.6 million. The first phase closed in December 2010 for $28 million, the second phase closed in January 2011 for $11.7 million and the third phase closed in June 2011 for $4.9 million. The amount received for the first and second phases was paid half in cash and half in MHR common stock while the amount received for the third phase was paid entirely in cash.
QER Loan
     Included in the $44.6 million aggregate purchase price paid by MHR was approximately $41.6 million representing the purchase price of assets owned by one of our subsidiaries, PostRock Eastern Production, LLC, formerly named Quest Eastern Resource LLC (“QER”), pledged as collateral under the QER Loan. From the sale proceeds, we made payments to the lender, Royal Bank of Canada (“RBC”), in the amount of $21.2 million in December 2010, $9.3 million in January 2011 and $4.3 million in June 2011. Concurrent with the June 2011 payment and pursuant to the terms of an asset sale agreement with RBC, we fully settled the outstanding balance of the QER Loan of approximately $843,000 by issuing 141,186 shares of our common stock with a fair value of $744,000 to RBC. We expect to recover the full amount of the $843,000 payment to RBC through the release of escrowed proceeds from the Appalachia Basin asset sale in June 2012.
     In connection with the sale, $6.4 million was set aside in escrow to cover potential claims for indemnity and title defects. The total first and second closing escrowed amount of $5.9 million is to be released in June 2012 while the third closing escrowed amount of $564,000 is to be released in December 2012. If all of the amounts in escrow are released, we would receive a total of $1.5 million, which includes $843,000 in connection with the QER Loan discussed above. The remaining amount would be released to RBC and a third-party.

Dilution
     At September 30, 2011, we had 9,503,396 shares of common stock issued and outstanding. In addition, White Deer holds warrants to purchase 20,840,596 shares of common stock at a weighted average exercise price of $3.25, CEG holds warrants to purchase 673,822 shares of common stock at a weighted average exercise price of $7.07 and we had 144,456 unvested restricted stock units outstanding. Consequently, if these shares were included as outstanding, our outstanding shares would be 31,162,270 of which White Deer’s warrants represent approximately 67%. By exercising their warrants, White Deer can benefit from their respective percentage of all of our profits and growth. In addition, if White Deer begins to sell significant amounts of our common stock, or if public markets perceive that they may sell significant amounts of our common stock, the market price of our common stock may be significantly impacted.
Contractual Obligations
     We have numerous contractual commitments in the ordinary course of business, debt service requirements and operating lease commitments. During the first quarter of 2011, we entered into new operating leases for compressors utilized in our gathering system. The leases convert already utilized compressors from month-to-month to a specified term lease. As a result, the $900,000 minimum amount of these contracts would be an increase to the amount included in our outstanding commitments table at December 31, 2010. We also extended the term of a leased facility in Olathe, Kansas, in August 2011 for an additional five years to December 2016, for a total commitment of $335,000.
     Other than the compressor leases, lease extension and debt repayments during the nine months ended September 30, 2011, there were no material changes to our commitments since December 31, 2010.

ITEM 4. CONTROLS AND PROCEDURES
     Disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934) are designed to ensure that information required to be disclosed in reports filed or submitted under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in SEC rules and forms and that such information is accumulated and communicated to management, including the principal executive officer and the principal financial officer, to allow timely decisions regarding required disclosures. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives.
     In connection with the preparation of this quarterly report on Form 10-Q, our management, under the supervision and with the participation of our principal executive officer and principal financial officer, conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of September 30, 2011. Based on that evaluation, our principal executive officer and principal financial officer concluded that, as of September 30, 2011, our disclosure controls and procedures were effective with respect to the recording, processing, summarizing and reporting, within the time periods specified in the SEC’s rules and forms, of information required to be disclosed by us in the reports that we file or submit under the Exchange Act.
     There were no changes in internal control over financial reporting that occurred during the quarter covered by this report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

The agreements have been filed to provide investors with information regarding their respective terms. The agreements are not intended to provide any other factual information about the Company or its business or operations. In particular, the assertions embodied in any representations, warranties and covenants contained in the agreements may be subject to qualifications with respect to knowledge and materiality different from those applicable to investors and may be qualified by information in confidential disclosure schedules no included with the exhibits. These disclosure schedules may contain information that modifies, qualifies and creates exceptions to the representations, warranties and covenants set forth in the agreements. Moreover, certain representations, warranties and covenants in the agreements may have been used for the purpose of allocating risk between the parties, rather than establishing matters as facts. In addition, information concerning the subject matter of the representations, warranties and covenants may have changed after the date of the respective agreement, which subsequent information may or may not be fully reflected in the Company’s public disclosures. Accordingly, investors should not rely on the representations, warranties and covenants in the agreements as characterizations of the actual state of facts about the Company or its business or operations on the date hereof.
