The information provided in this Quarterly Report on Form 10-Q/A only reflects the financial condition and results of operations of the Predecessor.

Summary of significant accounting policies	2. Principles of Combination The accompanying condensed combined financial statements include the accounts of Grey Rock III-A, Grey Rock III-B Holdings, Grey Rock III-B and Grey Rock PLP III all of which share common ownership and management. All inter-entity balances and transactions have been eliminated in combination. Basis of Presentation The condensed combined balance sheet as of December 31, 2021 was derived from the audited combined financial statements, and the unaudited interim condensed combined financial statements as of September 30, 2022 and for the three and nine month periods ended September 30, 2022 and 2021, provided herein have been prepared in accordance with the instructions for the Securities and Exchange Commission’s (“SEC’s”) Form 10-Q and Article 10 of Regulation S-X. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) have been condensed or omitted pursuant to rules and regulations of the SEC. However, in the Partnership’s opinion, the disclosures made therein are adequate to make the information presented not misleading. The Partnership believes these condensed combined financial statements include all normal recurring adjustments necessary to fairly present the results of the interim periods. The condensed combined statements of income for the three and nine months ended September 30, 2022 and the condensed combined results of cash flows for the nine months ended September 30, 2022 are not necessarily indicative of the combined statements of income and results of cash flows that might be expected for the entire year. These condensed combined financial statements and the accompanying notes should be read in conjunction with the audited combined financial statements and the notes thereto for the year ended December 31, 2021. The Partnership operates in a single operating and reportable segment. Operating segments are defined as components of an enterprise for which separate financial information is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and assess performance. The Partnership’s chief operating decision maker allocates resources and assesses performance based upon financial information at the Partnership level. Restatement of Previously Issued Condensed Combined Financial Statements On November 14, 2022, Granite Ridge filed a Quarterly Report on Form 10-Q reflecting the financial condition and results of operations of Fund III as of September 30, 2022 and December 31, 2021 and for the three and nine months ended September 30, 2022 and 2021. Fund III operated the majority of the historical business and was identified as the acquirer and Predecessor upon consummation of the business combination on October 24, 2022. Since the business combination was completed subsequent to the end of the period covered by this Quarterly Report on Form 10-Q/A, the information provided regarding the Predecessor did not include financial or other information regarding the other entities who were parties to the business combination or whose assets became part of the business combination. ​ In connection with the preparation of the consolidated financial statements for the year ended December 31, 2022, the Company identified errors in its previously filed unaudited condensed combined financial statements of the Predecessor as of September 30, 2022 and for the three and nine months ended September 30, 2022. The Company discovered errors in the depletion calculation and that certain acquisitions, initially classified as acquisitions of proved oil and natural gas properties, should have been classified as unproved oil and natural gas properties which overstated depletion expense for the three and nine months ended September 30, 2022. Depletion expense for Fund III was overstated by $14.1 million for the three and nine months ended September 30, 2022. ​ In connection with these errors, the Company is restating the previously issued unaudited condensed combined financial statements of the Predecessor as of and for the three and nine month periods ended September 30, 2022, as filed in the Company’s Quarterly Report on Form 10-Q on November 14, 2022. The restatement does not impact the Company’s current or historical reported revenue, liquidity, cash and cash equivalents or cash flows from (used in) operating, investing or financing activities. ​ The Company’s financial statements as of and for the three and nine months ended September 30, 2022 included in this Form 10-Q/A have been restated to correct the errors as follows: ​ Condensed Combined Balance Sheet ​ ​ ​ ​ ​ ​ ​ As of September 30, 2022 (in thousands) As Previously Reported ​ Adjustments ​ As Restated ASSETS ​ ​ ​ ​ ​ Current assets: ​ ​ ​ ​ ​ Cash $6,410 ​ $- ​ $6,410 Revenue receivable 54,324 ​ - ​ 54,324 Advances to operators 26,230 ​ - ​ 26,230 Other assets 4,098 ​ - ​ 4,098 Other Receivable - ​ - ​ - Derivative assets 4,376 ​ - ​ 4,376 Contributions receivable 10 ​ - ​ 10 Total current assets 95,448 ​ - ​ 95,448 Property and equipment: ​ ​ ​ ​ ​ Oil and natural gas properties, successful efforts method 550,163 ​ ​ ​ 550,163 Accumulated depletion (168,302) ​ 14,082 ​ (154,220) Total property and equipment, net 381,861 ​ 14,082 ​ 395,943 Long-term assets: ​ ​ ​ ​ ​ Derivative assets 812 ​ - ​ 812 Total long-term assets 812 ​ - ​ 812 TOTAL ASSETS $ 478,121 ​ $ 14,082 ​ $ 492,203 ​ ​ ​ ​ ​ ​ LIABILITIES AND PARTNERS' CAPITAL ​ ​ ​ ​ ​ Current liabilities: ​ ​ ​ ​ ​ Accrued expenses $ 20,595 ​ $ - ​ $ 20,595 Derivative liabilities 3,941 ​ - ​ 3,941 Credit facilities - ​ - ​ - Total current liabilities 24,536 ​ - ​ 24,536 Long-term liabilities: ​ ​ ​ ​ ​ Derivative liabilities - ​ - ​ - Asset retirement obligations 2,243 ​ - ​ 2,243 Total long-term liabilities 2,243 ​ - ​ 2,243 TOTAL LIABILITIES 26,779 ​ - ​ 26,779 ​ ​ ​ ​ ​ ​ Commitments and contingencies (Note 8) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Partners' capital: ​ ​ ​ ​ ​ General partner 41,614 ​ 112 ​ 41,726 Limited partners 409,728 ​ 13,970 ​ 423,698 Total partners' capital 451,342 ​ 14,082 ​ 465,424 TOTAL LIABILITIES AND EQUITY $ 478,121 ​ $ 14,082 ​ $ 492,203 ​ Condensed Combined Statements of Operations ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended September 30, 2022 ​ Nine months ended September 30, 2022 (in thousands) As Previously Reported ​ Adjustments ​ As Restated ​ As Previously Reported ​ Adjustments ​ As Restated REVENUES ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Oil, natural gas, and related product sales, net $ 90,194 ​ $ - ​ $ 90,194 ​ $ 263,263 ​ $ - ​ $ 263,263 EXPENSES ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Lease operating expenses 6,368 ​ - ​ 6,368 ​ 15,840 ​ - ​ 15,840 Production taxes 5,053 ​ - ​ 5,053 ​ 14,628 ​ - ​ 14,628 Depletion and accretion expense 39,868 ​ (14,082) ​ 25,786 ​ 70,529 ​ (14,082) ​ 56,447 General and administrative 1,776 ​ - ​ 1,776 ​ 4,880 ​ - ​ 4,880 Total expenses 53,065 ​ (14,082) ​ 38,983 ​ 105,877 ​ (14,082) ​ 91,795 Net operating income 37,129 ​ 14,082 ​ 51,211 ​ 157,386 ​ 14,082 ​ 171,468 OTHER INCOME/(EXPENSE) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Gain/(loss) on derivative contracts 6,082 ​ - ​ 6,082 ​ (19,147) ​ - ​ (19,147) Interest expense (476) ​ - ​ (476) ​ (1,193) ​ - ​ (1,193) Total other income/(expense) 5,606 ​ - ​ 5,606 ​ (20,340) ​ - ​ (20,340) NET INCOME $ 42,735 ​ $ 14,082 ​ $ 56,817 ​ $ 137,046 ​ $ 14,082 ​ $ 151,128 ​ Condensed Combined Statements of Changes in Partners’ Capital ​ ​ ​ ​ ​ ​ (in thousands) General Partner ​ Limited Partners ​ Total Net income (As Previously Reported) $ 340 ​ $ 42,395 ​ $ 42,735 Adjustments 112 ​ 13,970 ​ 14,082 Net income (As Restated) $ 452 ​ $ 56,365 ​ $ 56,817 ​ Condensed Combined Statements of Cash Flows ​ ​ ​ ​ ​ ​ ​ Nine months ended September 30, 2022 (in thousands) As Previously Reported ​ Adjustments ​ As Restated Operating activities: ​ ​ ​ ​ ​ Net income $ 137,046 ​ $ 14,082 ​ $ 151,128 Adjustments to reconcile net income to net cash provided by operating activities: ​ ​ ​ ​ ​ Depletion and accretion expense 70,529 ​ (14,082) ​ 56,447 Change in unrealized (gain) loss on derivative contracts (5,600) ​ - ​ (5,600) Amortization of loan origination costs 62 ​ - ​ 62 Increase (decrease) in cash attributable to changes in operating assets and liabilities: ​ ​ ​ ​ - Revenue receivable (21,627) ​ - ​ (21,627) Prepaid expenses (4,028) ​ - ​ (4,028) Other assets 469 ​ - ​ 469 Accrued expenses 2,811 ​ - ​ 2,811 Net cash provided by operating activities $ 179,662 ​ - ​ $ 179,662 ​ The remainder of the notes to the condensed combined financial statements have been updated and restated, as applicable, to reflect the impacts of the restatement described above. Fair Value The Partnership has adopted and follows Accounting Standard Codification (“ASC”) 820, Fair Value Measurements and Disclosures Level 1 — Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date. Level 2 — Inputs (other than quoted market prices included in Level 1) are either directly or indirectly observable for the asset or liability through correlation with market data at the measurement date and for the duration of the instrument’s anticipated life. Level 3 — Inputs reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model. Valuation of instruments includes unobservable inputs to the valuation methodology that are significant to the measurement of fair value of assets or liabilities. As defined by ASC 820, the fair value of a financial instrument is the amount at which the instrument could be exchanged in a current transaction between willing parties, other than in a forced or liquidation sale, which was further clarified as the price that would be received to sell an asset or paid to transfer a liability (“an exit price”) in an orderly transaction between market participants at the measurement date. The carrying amounts of the Partnership’s financial assets and liabilities, such as due from related parties, revenue receivable, related party payable, accounts payable and accrued expenses, approximate their fair values because of the short maturity of these instruments. Revenue Receivable Revenue receivable is comprised of accrued natural gas and crude oil sales. The operators remit payment for production directly to the Partnership. There have been no credit losses to date. In the event of complete non-performance by the Partnership’s customers, the maximum exposure to the Partnership is the outstanding revenue receivable balance at the date of non-performance. The Partnership writes off specific accounts receivable when they become uncollectible. For the three and nine months ended September 30, 2022 and 2021, the Partnership had no bad debt expense, and did not record an allowance for doubtful accounts. Other Assets Other assets are comprised of payments made in advance for services deemed to have future value to the Partnership and fees that were capitalized in connection to the Business Combination. Capitalized fees were $4,098 thousand and zero as of September 30, 2022 and December 31, 2021, respectively. Prepaid expenses were zero and $70 thousand as of September 30, 2022 and December 31, 2021, respectively. Revenue Recognition The Partnership’s revenues are primarily derived from its interests in the sale of oil and natural gas production. The Partnership recognizes revenue from its interests in the sales of oil and natural gas in the period that its performance obligations are satisfied. Performance obligations are satisfied when the customer obtains control of product and when the Partnership has no further obligations to perform related to the sale. The Partnership receives payment from the sale of oil and natural gas production from one three The Partnership does not disclose the value of unsatisfied performance obligations under its contracts with customers as it applies the practical expedient in accordance with ASC 606. The expedient, as described in ASC 606-10-50-14(a), applies to variable consideration that is recognized as control of the product is transferred to the customer. Since each unit of product represents a separate performance obligation, future volumes are wholly unsatisfied, and disclosure of the transaction price allocated to remaining performance obligations is not required. A wellhead imbalance liability equal to the Partnership’s share is recorded to the extent that the Partnership’s well operators have sold volumes in excess of its share of remaining reserves in an underlying property. However, in each of the three and nine months ended September 30, 2022 and 2021, the Partnership’s oil and natural gas production was in balance, meaning its cumulative portion of oil and natural gas production taken and sold from wells in which it has an interest equaled its entitled interest in oil and natural gas production from those wells. Non-operated crude oil and natural gas revenues – The Partnership’s proportionate share of production from non-operated properties is generally marketed at the discretion of the operators. For non-operated properties, the Partnership receives a net payment from the operator representing its proportionate share of sales proceeds which is net of transportation and production tax costs incurred by the operator, if any. Such non-operated revenues are recognized at the net of transportation costs which is the amount of proceeds to be received by the Partnership during the month in which production occurs and it is probable the Partnership will collect the consideration it is entitled to receive. Proceeds are generally received by the Partnership within one three Substantially all of the Partnership’s oil and natural gas sales currently come from four geographic areas in the United States: the Eagle Ford Basin (Texas), the Permian Basin (Texas), the Denver-Julesburg “DJ” Basin (Colorado) and the Bakken Basin (Montana/North Dakota). The following tables present the disaggregation of the Partnership’s oil revenues and natural gas and NGL revenues by basin for the three and nine months ended September 30, 2022 and 2021. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended September 30, 2022 (in thousands) Eagle Ford Permian Denver-Julesberg Bakken ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Revenues ​ $ 11,891 ​ $ 65,997 $ 8,271 ​ $ 4,035 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended September 30, 2021 (in thousands) Eagle Ford Permian Denver-Julesberg Bakken ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Revenues ​ $ 4,575 ​ $ 39,252 ​ $ 10,726 ​ $ 1,164 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Nine months ended September 30, 2022 (in thousands) Eagle Ford Permian Denver-Julesberg Bakken ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Revenues ​ $ 35,978 ​ $ 186,853 ​ $ 30,370 ​ $ 10,062 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Nine months ended September 30, 2021 (in thousands) Eagle Ford Permian Denver-Julesberg Bakken ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Revenues ​ $ 22,002 ​ $ 97,926 ​ $ 19,801 ​ $ 2,903 ​ Income Taxes Because the Partnership is a limited partnership, the income or loss of the Partnership for federal and state income tax purposes is generally allocated to the partners in accordance with the Partnership’s formation documents, and it is the responsibility of the partners to report their share of taxable income or loss on their separate income tax returns. Accordingly, no recognition has been given to federal or state income taxes in the accompanying condensed combined financial statements. The Partnership is required to determine whether its tax positions are more likely than not to be sustained upon examination by the applicable taxing authority, including resolution of any related appeals or litigation processes, based on the technical merits of the position. The tax benefit recognized is measured as the largest amount of benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement with the relevant taxing authority. De-recognition of a tax benefit previously recognized results in the Partnership recording a tax liability that reduces ending partners’ capital. Based on its analysis, the Partnership has determined that it has not incurred any liability for unrecognized tax benefits as of September 30, 2022 and December 31, 2021. However, the Partnership’s conclusions may be subject to review and adjustment at a later date based on factors including, but not limited to, on-going analyses of and changes to tax laws, regulations and interpretations thereof. The Partnership recognizes interest and penalties related to unrecognized tax benefits in interest expense and other expenses, respectively. No interest or penalties were recognized for the three and nine months ended September 30, 2022 and 2021. The Partnership files an income tax return in the U.S. federal jurisdiction, and may file income tax returns in various U.S. states and foreign jurisdictions. Generally, the Partnership is subject to income tax examinations by major taxing authorities during the period since inception. The Partnership may be subject to potential examination by U.S. federal, U.S. states or foreign jurisdiction authorities in the areas of income taxes. These potential examinations may include questioning the timing and amount of deductions, the nexus of income among various tax jurisdictions and compliance with U.S. federal, U.S. state and foreign tax laws. The Partnership’s management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months. Reclassifications Certain reclassifications have been made to prior period amounts to conform to the current period presentation. Use of Estimates The preparation of the condensed combined financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the condensed combined financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates of reserves are used to determine depletion and to conduct impairment analysis. Estimating reserves is inherently uncertain, including the projection of future rates of production and the timing of development expenditures. Additional significant estimates include impairment testing, derivative instruments and hedging activity, and asset retirement obligations. Actual results could differ from those estimates. Recently Issued and Applicable Accounting Pronouncements The FASB issued ASU No. 2016-02, “Leases (Topic 842)” which requires all leases greater than one year to be recognized as assets and liabilities. This ASU also expands the required quantitative and qualitative disclosures surrounding leases. Oil and gas leases are excluded from the guidance. The Partnership adopted this ASU on January 1, 2022, and there was no material impacts to the condensed combined financial statements. The FASB issued ASU No. 2016-13, “Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” which introduces guidance for estimating credit losses on certain types of financial instruments based on expected losses and the timing of the recognition of such losses. This guidance becomes effective beginning on January 1, 2023, however, the impact is not expected to be material.

Derivative instruments

Derivative instruments
Derivative instruments	3. From time to time, the Partnership may utilize derivative contracts in connection with its oil and natural gas operations to provide an economic hedge of the Partnership’s exposure to commodity price risk associated with anticipated future oil and natural gas production. The Partnership does not hold or issue derivative financial instruments for trading purposes. These derivative contracts consist of fixed price collar options and producer 3-way option contracts. The Partnership typically hedges approximately 50% to 75% of expected oil and natural gas production from the underlying entities for 12 Derivative Contracts The Partnership has not designated its derivative instruments as hedges for accounting purposes. Cash and non-cash changes in fair value are included in gain or loss on derivative contracts in the condensed combined statements of income. Derivative assets are included within current and noncurrent assets in the condensed combined balance sheets as of September 30, 2022. Derivative liabilities are included within current liabilities in the condensed combined balance sheets as of September 30, 2022. Derivative assets and liabilities are included within current and noncurrent liabilities in the condensed combined balance sheets as of December 31, 2021. Collar and Producer 3-way Option Contracts A collar option is established with the sale of a short call option and the purchase of a long put option set to expire at a predetermined date in the future. The options give the owner the right but not the obligation to exercise the option at the expiration date. A producer 3-way contract, like a collar option, is established with the sale of a short call option and the purchase of a long put option set to expire at a predetermined date in the future. However, the producer 3-way contract also includes the sale of a short put option set to expire at a predetermined date in the future. The options give the owner the right but not the obligation to exercise the option at the expiration date. The fair value of open collar options and producer 3-way contracts reported in the condensed combined balance sheets may differ from that which would be realized in the event the Partnership terminated its position in the contract. Risks may arise as a result of the failure of the counterparty to the option contract to comply with the terms of the option contract. The loss incurred by the failure of counterparties is generally limited to the aggregate fair value of option contracts in an unrealized gain position as well as any collateral posted with the counterparty. The Partnership considers the creditworthiness of each counterparty to an option contract in evaluating potential credit risk. Additionally, risks may arise from unanticipated movements in the fair value of the underlying investments. The Partnership has master netting agreements on individual derivative instruments with certain counterparties and therefore certain amounts may be presented on a net basis in the condensed combined balance sheets. Volume of Derivative Activities At September 30, 2022, the volume of the Partnership’s derivative activities based on their volume (crude oil is presented in Bbl and natural gas is presented in Mcf) and contract prices, categorized by primary underlying risk, are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Contract Prices Period Type of Contract (Volume/Month) Range Weighted Average Oct 2022 – Dec 2023 ​ Producer 3-way (crude oil) ​ 34,413 – 612 ​ $113.10 – $40.00 ​ ​ $75.16 Oct 2022 – Dec 2022 ​ Collar (crude oil) ​ 33,886 – 5,448 ​ $112.75 – $85.00 ​ ​ $97.24 Nov 2022 – Mar 2023 ​ Producer 3-way (natural gas) ​ 128,912 – 3,813 ​ $8.44 – $3.00 ​ ​ $5.13 Nov 2022 – Jun 2023 ​ Collar (natural gas) ​ 90,941 – 11,036 ​ $9.05 – $2.90 ​ ​ $5.48 ​ Impact of Derivatives on the Condensed Combined Balance Sheets and Condensed Combined Statements of Income.

Fair value measurements	4. Fair Values – Recurring As required, financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Partnership’s assessment of the significance of a particular input requires judgment and may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy levels. The following table presents information about the Partnership’s recurring assets and liabilities measured at fair value as of September 30, 2022: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ September 30, (in thousands) Level 1 Level 2 Level 3 2022 Assets (at fair value): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Derivative contracts ​ $ — ​ $ 5,188 ​ $ — ​ $ 5,188 Liabilities (at fair value): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Derivative contracts ​ $ — ​ $ (3,941) ​ $ — ​ $ (3,941) ​ The following table presents information about the Partnership’s recurring liabilities measured at fair value as of December 31, 2021: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, (in thousands) Level 1 Level 2 Level 3 2021 Liabilities (at fair value): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Derivative contracts ​ $ — ​ $ (4,353) ​ $ — ​ $ (4,353) ​ The following table provides the fair value of financial instruments that are not recorded at fair value in the condensed combined balance sheets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ September 30, 2022 ​ December 31, 2021 ​ (in thousands) Carrying Value Fair Value Carrying Value Fair Value Liabilities (at fair value): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Revolving Credit Facility ​ $ — ​ $ — ​ $ 29,938 ​ $ 29,938 ​ ​ The recorded value of the revolving credit facility approximates its fair value because of its floating rate structure based on the Prime Rate spread. The fair value measurement for the revolving credit facility represents Level 2 inputs. Fair Values - Non Recurring The fair value measurements of asset retirement obligations are measured on a nonrecurring basis when a well is drilled or acquired or when production equipment and facilities are installed or acquired using a discounted cash flow model based on inputs that are not observable in the market and therefore represent Level 3 inputs. Significant inputs to the fair value measurement of asset retirement obligations include estimates of the costs of plugging and abandoning oil and natural gas wells, removing production equipment and facilities and restoring the surface of the land as well as estimates of the economic lives of the oil and natural gas wells and future inflation rates. Asset retirement obligations incurred and acquired during the nine months ended September 30, 2022 were approximately $633 thousand.

All limited partners of Grey Rock III-B Holdings are considered affiliates of the General Partner. Allocation of Net Profits and Losses The Partnership’s net profits or losses for any fiscal period shall be allocated among the partners in such manner that, as of the end of such fiscal period and to the greatest extent possible, the capital account of each partner shall be equal to the respective net amount, positive or negative, that would be distributed to such partner from the Partnership or for which such partner would be liable to the Partnership, determined as if, on the last day of such fiscal period, the Partnership were to (a) liquidate the assets of the Partnership for an amount equal to their book value and (b) distribute the proceeds in liquidation. (a) First, 100% to such partner until such partner has received cumulative distributions equal to such partner’s aggregate capital contributions to the Partnership for any purpose; (b) Second, 100% to such partner until the aggregate distributions to such partner equal the preferred return amount of 8% per annum on the partner’s capital contributions; (c) Third, 80% to the General Partner and 20% to such partner until the General Partner has received cumulative distributions equal to 20% of the cumulative amount of distributions made pursuant to (c) and previously made pursuant to (b); and (d) Thereafter, 20% to the General Partner and 80% to such partner. The reallocation to the general partner from the limited partners was approximately $6,654 thousand and $25,623 thousand for the three and nine months ended September 30, 2022, respectively. The reallocation to the general partner from the limited partners was approximately $12,856 thousand for the three and nine months ended September 30, 2021. The allocation of carried interest will remain provisional until the final liquidation of the Partnership. Distributions In accordance with the Limited Partnership Agreement (“LPA”), all distributions shall be made, at such times and in such amounts as determined in the sole discretion of the General Partner, to the partners in proportion to their Partnership percentage interests. For the three and nine months ended September 30, 2022 and 2021, the Partnership did not make any distributions.

Commitments and contingencies	8. The Partnership is subject to various possible contingencies that arise primarily from interpretation of federal and state laws and regulations affecting the oil and natural gas industry. Such contingencies include differing interpretations as to the prices at which oil and natural gas sales may be made, the prices at which royalty owners may be paid for production from their leases, environmental issues, and other matters. Although management believes that it has complied with the various laws and regulations, administrative rulings, and interpretations thereof, adjustments could be required as new interpretations and regulations are issued. In addition, environmental matters are subject to regulation by various federal and state agencies. The Partnership is currently not a party to any material pending legal proceedings that would give rise to potential loss contingencies. As of September 30, 2022, the Partnership had incurred approximately $ thousand in capital expenditures that were included in accounts payable, and the Partnership estimates that it is committed to an additional approximately $50,000 thousand in development capital expenditures not yet incurred for wells the Partnership elected to participate in.

Risk concentrations
Risk concentrations	10. As a non-operator, 100% of the Partnership’s wells are operated by third-party operating partners. As a result, the Partnership is highly dependent on the success of these third-party operators. If they are not successful in the development, exploitation, production and exploration activities relating to the Partnership’s leasehold interests, or are unable or unwilling to perform, the Partnership’s financial condition and results of operation could be adversely affected. These risks are heightened in a low commodity price environment, which may present significant challenges to these third-party operators. The Partnership’s third-party operators will make decisions in connection with their operations that may not be in the Partnership’s best interests, and the Partnership may have little or no ability to exercise influence over the operational decisions of its third-party operators . In the normal course of business, the Partnership maintains its cash balances in financial institutions, which at times may exceed federally insured limits. The Partnership is subject to credit risk to the extent any financial institution with which it conducts business is unable to fulfill contractual obligations on its behalf. Management monitors the financial condition of such financial institutions and does not anticipate any losses from these counterparties. The outbreak of the novel coronavirus and the military conflict between Russia and Ukraine continue to significantly impact the worldwide economy and specific economic sectors. As a result, commodity prices remain volatile, which may impact the Partnership’s performance and may lead to future losses.

Subsequent events	11. In connection with preparing the condensed combined financial statements for the three and nine months ended September 30, 2022, management has evaluated subsequent events for potential recognition and disclosure through the date November 14, 2022, which is the date the condensed combined financial statements were available to be issued. As discussed in Note 1—Nature of Operations, on May 16, 2022, GREP entered into a business combination agreement with ENPC, a NYSE publicly traded special purpose acquisition company and Granite Ridge. The Business Combination closed on October 24, 2022 as a result of which GREP and ENPC became wholly-owned subsidiaries of Granite Ridge. Granite Ridge’s common stock and warrants are listed on the NYSE. Refer to Note 1 for additional information. On October 24, 2022, Granite Ridge entered into a senior secured revolving credit agreement (the “Credit Agreement”) among Granite Ridge, as borrower, Texas Capital Bank, as administrative agent, and the lenders from time to time party thereto. The Credit Agreement has a maturity date of five years from the effective date thereof. The Credit Agreement provides for aggregate elected commitments of $150.0 million, an initial borrowing base of $325.0 million and an aggregate maximum revolving credit amount of $1,000.0 million. The borrowing base is scheduled to be redetermined semiannually on or about April 1 and October 1 of each calendar year, commencing April 1, 2023, and is subject to additional adjustments from time to time, including for asset sales, elimination or reduction of hedge positions and incurrence of other debt. Additionally, the borrower and each of the Required Lenders (as defined in the Credit Agreement) may request one unscheduled redetermination of the borrowing base between each scheduled redetermination. The amount of the borrowing base is determined by the lenders in their sole discretion and consistent with the oil and gas lending criteria of the lenders at the time of the relevant redetermination. The amount Granite Ridge is able to borrow under the Credit Agreement is subject to compliance with the financial covenants, satisfaction of various conditions precedent to borrowing and other provisions of the Credit Agreement. Granite Ridge does not have any borrowings or letters of credit outstanding under the Credit Agreement, resulting in availability of $150.0 million. The Credit Agreement is guaranteed by the restricted subsidiaries of Granite Ridge and is secured by a first priority mortgage and security interest in substantially all assets of the Company and its restricted subsidiaries. In conjunction with the Credit Agreement, on October 24, 2022, all derivative contracts outstanding with GREP were novated to Granite Ridge. Granite Ridge’s board of directors recently declared a dividend of $0.08 per share of Granite Ridge’s common stock. The dividend is payable on December 15, 2022 to stockholders of record on December 1, 2022. This dividend payout is aligned with Granite Ridge’s intent to pay a minimum dividend of $60 million per year to its shareholders, which would currently equate to $0.45 per share annually or an approximate five percent dividend yield. The initial common dividend was prorated to October 24, 2022, the effective date of Granite Ridge’s business combination, which equaled $0.08 per common share for the quarter.

All inter-entity balances and transactions have been eliminated in combination.
Basis of Presentation		Basis of Presentation The condensed combined balance sheet as of December 31, 2021 was derived from the audited combined financial statements, and the unaudited interim condensed combined financial statements as of September 30, 2022 and for the three and nine month periods ended September 30, 2022 and 2021, provided herein have been prepared in accordance with the instructions for the Securities and Exchange Commission’s (“SEC’s”) Form 10-Q and Article 10 of Regulation S-X. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) have been condensed or omitted pursuant to rules and regulations of the SEC. However, in the Partnership’s opinion, the disclosures made therein are adequate to make the information presented not misleading. The Partnership believes these condensed combined financial statements include all normal recurring adjustments necessary to fairly present the results of the interim periods. The condensed combined statements of income for the three and nine months ended September 30, 2022 and the condensed combined results of cash flows for the nine months ended September 30, 2022 are not necessarily indicative of the combined statements of income and results of cash flows that might be expected for the entire year. These condensed combined financial statements and the accompanying notes should be read in conjunction with the audited combined financial statements and the notes thereto for the year ended December 31, 2021. The Partnership operates in a single operating and reportable segment. Operating segments are defined as components of an enterprise for which separate financial information is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and assess performance. The Partnership’s chief operating decision maker allocates resources and assesses performance based upon financial information at the Partnership level.
Restatement of Previously Issued Condensed Combined Financial Statements	Restatement of Previously Issued Condensed Combined Financial Statements On November 14, 2022, Granite Ridge filed a Quarterly Report on Form 10-Q reflecting the financial condition and results of operations of Fund III as of September 30, 2022 and December 31, 2021 and for the three and nine months ended September 30, 2022 and 2021. Fund III operated the majority of the historical business and was identified as the acquirer and Predecessor upon consummation of the business combination on October 24, 2022. Since the business combination was completed subsequent to the end of the period covered by this Quarterly Report on Form 10-Q/A, the information provided regarding the Predecessor did not include financial or other information regarding the other entities who were parties to the business combination or whose assets became part of the business combination. ​ In connection with the preparation of the consolidated financial statements for the year ended December 31, 2022, the Company identified errors in its previously filed unaudited condensed combined financial statements of the Predecessor as of September 30, 2022 and for the three and nine months ended September 30, 2022. The Company discovered errors in the depletion calculation and that certain acquisitions, initially classified as acquisitions of proved oil and natural gas properties, should have been classified as unproved oil and natural gas properties which overstated depletion expense for the three and nine months ended September 30, 2022. Depletion expense for Fund III was overstated by $14.1 million for the three and nine months ended September 30, 2022. ​ In connection with these errors, the Company is restating the previously issued unaudited condensed combined financial statements of the Predecessor as of and for the three and nine month periods ended September 30, 2022, as filed in the Company’s Quarterly Report on Form 10-Q on November 14, 2022. The restatement does not impact the Company’s current or historical reported revenue, liquidity, cash and cash equivalents or cash flows from (used in) operating, investing or financing activities. ​ The Company’s financial statements as of and for the three and nine months ended September 30, 2022 included in this Form 10-Q/A have been restated to correct the errors as follows: ​ Condensed Combined Balance Sheet ​ ​ ​ ​ ​ ​ ​ As of September 30, 2022 (in thousands) As Previously Reported ​ Adjustments ​ As Restated ASSETS ​ ​ ​ ​ ​ Current assets: ​ ​ ​ ​ ​ Cash $6,410 ​ $- ​ $6,410 Revenue receivable 54,324 ​ - ​ 54,324 Advances to operators 26,230 ​ - ​ 26,230 Other assets 4,098 ​ - ​ 4,098 Other Receivable - ​ - ​ - Derivative assets 4,376 ​ - ​ 4,376 Contributions receivable 10 ​ - ​ 10 Total current assets 95,448 ​ - ​ 95,448 Property and equipment: ​ ​ ​ ​ ​ Oil and natural gas properties, successful efforts method 550,163 ​ ​ ​ 550,163 Accumulated depletion (168,302) ​ 14,082 ​ (154,220) Total property and equipment, net 381,861 ​ 14,082 ​ 395,943 Long-term assets: ​ ​ ​ ​ ​ Derivative assets 812 ​ - ​ 812 Total long-term assets 812 ​ - ​ 812 TOTAL ASSETS $ 478,121 ​ $ 14,082 ​ $ 492,203 ​ ​ ​ ​ ​ ​ LIABILITIES AND PARTNERS' CAPITAL ​ ​ ​ ​ ​ Current liabilities: ​ ​ ​ ​ ​ Accrued expenses $ 20,595 ​ $ - ​ $ 20,595 Derivative liabilities 3,941 ​ - ​ 3,941 Credit facilities - ​ - ​ - Total current liabilities 24,536 ​ - ​ 24,536 Long-term liabilities: ​ ​ ​ ​ ​ Derivative liabilities - ​ - ​ - Asset retirement obligations 2,243 ​ - ​ 2,243 Total long-term liabilities 2,243 ​ - ​ 2,243 TOTAL LIABILITIES 26,779 ​ - ​ 26,779 ​ ​ ​ ​ ​ ​ Commitments and contingencies (Note 8) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Partners' capital: ​ ​ ​ ​ ​ General partner 41,614 ​ 112 ​ 41,726 Limited partners 409,728 ​ 13,970 ​ 423,698 Total partners' capital 451,342 ​ 14,082 ​ 465,424 TOTAL LIABILITIES AND EQUITY $ 478,121 ​ $ 14,082 ​ $ 492,203 ​ Condensed Combined Statements of Operations ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended September 30, 2022 ​ Nine months ended September 30, 2022 (in thousands) As Previously Reported ​ Adjustments ​ As Restated ​ As Previously Reported ​ Adjustments ​ As Restated REVENUES ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Oil, natural gas, and related product sales, net $ 90,194 ​ $ - ​ $ 90,194 ​ $ 263,263 ​ $ - ​ $ 263,263 EXPENSES ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Lease operating expenses 6,368 ​ - ​ 6,368 ​ 15,840 ​ - ​ 15,840 Production taxes 5,053 ​ - ​ 5,053 ​ 14,628 ​ - ​ 14,628 Depletion and accretion expense 39,868 ​ (14,082) ​ 25,786 ​ 70,529 ​ (14,082) ​ 56,447 General and administrative 1,776 ​ - ​ 1,776 ​ 4,880 ​ - ​ 4,880 Total expenses 53,065 ​ (14,082) ​ 38,983 ​ 105,877 ​ (14,082) ​ 91,795 Net operating income 37,129 ​ 14,082 ​ 51,211 ​ 157,386 ​ 14,082 ​ 171,468 OTHER INCOME/(EXPENSE) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Gain/(loss) on derivative contracts 6,082 ​ - ​ 6,082 ​ (19,147) ​ - ​ (19,147) Interest expense (476) ​ - ​ (476) ​ (1,193) ​ - ​ (1,193) Total other income/(expense) 5,606 ​ - ​ 5,606 ​ (20,340) ​ - ​ (20,340) NET INCOME $ 42,735 ​ $ 14,082 ​ $ 56,817 ​ $ 137,046 ​ $ 14,082 ​ $ 151,128 ​ Condensed Combined Statements of Changes in Partners’ Capital ​ ​ ​ ​ ​ ​ (in thousands) General Partner ​ Limited Partners ​ Total Net income (As Previously Reported) $ 340 ​ $ 42,395 ​ $ 42,735 Adjustments 112 ​ 13,970 ​ 14,082 Net income (As Restated) $ 452 ​ $ 56,365 ​ $ 56,817 ​ Condensed Combined Statements of Cash Flows ​ ​ ​ ​ ​ ​ ​ Nine months ended September 30, 2022 (in thousands) As Previously Reported ​ Adjustments ​ As Restated Operating activities: ​ ​ ​ ​ ​ Net income $ 137,046 ​ $ 14,082 ​ $ 151,128 Adjustments to reconcile net income to net cash provided by operating activities: ​ ​ ​ ​ ​ Depletion and accretion expense 70,529 ​ (14,082) ​ 56,447 Change in unrealized (gain) loss on derivative contracts (5,600) ​ - ​ (5,600) Amortization of loan origination costs 62 ​ - ​ 62 Increase (decrease) in cash attributable to changes in operating assets and liabilities: ​ ​ ​ ​ - Revenue receivable (21,627) ​ - ​ (21,627) Prepaid expenses (4,028) ​ - ​ (4,028) Other assets 469 ​ - ​ 469 Accrued expenses 2,811 ​ - ​ 2,811 Net cash provided by operating activities $ 179,662 ​ - ​ $ 179,662 ​ The remainder of the notes to the condensed combined financial statements have been updated and restated, as applicable, to reflect the impacts of the restatement described above.
Fair Value	Fair Value The Partnership has adopted and follows Accounting Standard Codification (“ASC”) 820, Fair Value Measurements and Disclosures Level 1 — Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date. Level 2 — Inputs (other than quoted market prices included in Level 1) are either directly or indirectly observable for the asset or liability through correlation with market data at the measurement date and for the duration of the instrument’s anticipated life. Level 3 — Inputs reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model. Valuation of instruments includes unobservable inputs to the valuation methodology that are significant to the measurement of fair value of assets or liabilities. As defined by ASC 820, the fair value of a financial instrument is the amount at which the instrument could be exchanged in a current transaction between willing parties, other than in a forced or liquidation sale, which was further clarified as the price that would be received to sell an asset or paid to transfer a liability (“an exit price”) in an orderly transaction between market participants at the measurement date. The carrying amounts of the Partnership’s financial assets and liabilities, such as due from related parties, revenue receivable, related party payable, accounts payable and accrued expenses, approximate their fair values because of the short maturity of these instruments.
Revenue Receivable	Revenue Receivable Revenue receivable is comprised of accrued natural gas and crude oil sales. The operators remit payment for production directly to the Partnership. There have been no credit losses to date. In the event of complete non-performance by the Partnership’s customers, the maximum exposure to the Partnership is the outstanding revenue receivable balance at the date of non-performance. The Partnership writes off specific accounts receivable when they become uncollectible. For the three and nine months ended September 30, 2022 and 2021, the Partnership had no bad debt expense, and did not record an allowance for doubtful accounts.
Other Assets	Other Assets Other assets are comprised of payments made in advance for services deemed to have future value to the Partnership and fees that were capitalized in connection to the Business Combination. Capitalized fees were $4,098 thousand and zero as of September 30, 2022 and December 31, 2021, respectively. Prepaid expenses were zero and $70 thousand as of September 30, 2022 and December 31, 2021, respectively.
Revenue Recognition	Revenue Recognition The Partnership’s revenues are primarily derived from its interests in the sale of oil and natural gas production. The Partnership recognizes revenue from its interests in the sales of oil and natural gas in the period that its performance obligations are satisfied. Performance obligations are satisfied when the customer obtains control of product and when the Partnership has no further obligations to perform related to the sale. The Partnership receives payment from the sale of oil and natural gas production from one three The Partnership does not disclose the value of unsatisfied performance obligations under its contracts with customers as it applies the practical expedient in accordance with ASC 606. The expedient, as described in ASC 606-10-50-14(a), applies to variable consideration that is recognized as control of the product is transferred to the customer. Since each unit of product represents a separate performance obligation, future volumes are wholly unsatisfied, and disclosure of the transaction price allocated to remaining performance obligations is not required. A wellhead imbalance liability equal to the Partnership’s share is recorded to the extent that the Partnership’s well operators have sold volumes in excess of its share of remaining reserves in an underlying property. However, in each of the three and nine months ended September 30, 2022 and 2021, the Partnership’s oil and natural gas production was in balance, meaning its cumulative portion of oil and natural gas production taken and sold from wells in which it has an interest equaled its entitled interest in oil and natural gas production from those wells. Non-operated crude oil and natural gas revenues – The Partnership’s proportionate share of production from non-operated properties is generally marketed at the discretion of the operators. For non-operated properties, the Partnership receives a net payment from the operator representing its proportionate share of sales proceeds which is net of transportation and production tax costs incurred by the operator, if any. Such non-operated revenues are recognized at the net of transportation costs which is the amount of proceeds to be received by the Partnership during the month in which production occurs and it is probable the Partnership will collect the consideration it is entitled to receive. Proceeds are generally received by the Partnership within one three Substantially all of the Partnership’s oil and natural gas sales currently come from four geographic areas in the United States: the Eagle Ford Basin (Texas), the Permian Basin (Texas), the Denver-Julesburg “DJ” Basin (Colorado) and the Bakken Basin (Montana/North Dakota). The following tables present the disaggregation of the Partnership’s oil revenues and natural gas and NGL revenues by basin for the three and nine months ended September 30, 2022 and 2021. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended September 30, 2022 (in thousands) Eagle Ford Permian Denver-Julesberg Bakken ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Revenues ​ $ 11,891 ​ $ 65,997 $ 8,271 ​ $ 4,035 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended September 30, 2021 (in thousands) Eagle Ford Permian Denver-Julesberg Bakken ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Revenues ​ $ 4,575 ​ $ 39,252 ​ $ 10,726 ​ $ 1,164 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Nine months ended September 30, 2022 (in thousands) Eagle Ford Permian Denver-Julesberg Bakken ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Revenues ​ $ 35,978 ​ $ 186,853 ​ $ 30,370 ​ $ 10,062 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Nine months ended September 30, 2021 (in thousands) Eagle Ford Permian Denver-Julesberg Bakken ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Revenues ​ $ 22,002 ​ $ 97,926 ​ $ 19,801 ​ $ 2,903 ​
Income Taxes	Income Taxes Because the Partnership is a limited partnership, the income or loss of the Partnership for federal and state income tax purposes is generally allocated to the partners in accordance with the Partnership’s formation documents, and it is the responsibility of the partners to report their share of taxable income or loss on their separate income tax returns. Accordingly, no recognition has been given to federal or state income taxes in the accompanying condensed combined financial statements. The Partnership is required to determine whether its tax positions are more likely than not to be sustained upon examination by the applicable taxing authority, including resolution of any related appeals or litigation processes, based on the technical merits of the position. The tax benefit recognized is measured as the largest amount of benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement with the relevant taxing authority. De-recognition of a tax benefit previously recognized results in the Partnership recording a tax liability that reduces ending partners’ capital. Based on its analysis, the Partnership has determined that it has not incurred any liability for unrecognized tax benefits as of September 30, 2022 and December 31, 2021. However, the Partnership’s conclusions may be subject to review and adjustment at a later date based on factors including, but not limited to, on-going analyses of and changes to tax laws, regulations and interpretations thereof. The Partnership recognizes interest and penalties related to unrecognized tax benefits in interest expense and other expenses, respectively. No interest or penalties were recognized for the three and nine months ended September 30, 2022 and 2021. The Partnership files an income tax return in the U.S. federal jurisdiction, and may file income tax returns in various U.S. states and foreign jurisdictions. Generally, the Partnership is subject to income tax examinations by major taxing authorities during the period since inception. The Partnership may be subject to potential examination by U.S. federal, U.S. states or foreign jurisdiction authorities in the areas of income taxes. These potential examinations may include questioning the timing and amount of deductions, the nexus of income among various tax jurisdictions and compliance with U.S. federal, U.S. state and foreign tax laws. The Partnership’s management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months. Reclassifications Certain reclassifications have been made to prior period amounts to conform to the current period presentation.
Use of Estimates	Use of Estimates The preparation of the condensed combined financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the condensed combined financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates of reserves are used to determine depletion and to conduct impairment analysis. Estimating reserves is inherently uncertain, including the projection of future rates of production and the timing of development expenditures. Additional significant estimates include impairment testing, derivative instruments and hedging activity, and asset retirement obligations. Actual results could differ from those estimates.
Recently Issued and Applicable Accounting Pronouncements	Recently Issued and Applicable Accounting Pronouncements The FASB issued ASU No. 2016-02, “Leases (Topic 842)” which requires all leases greater than one year to be recognized as assets and liabilities. This ASU also expands the required quantitative and qualitative disclosures surrounding leases. Oil and gas leases are excluded from the guidance. The Partnership adopted this ASU on January 1, 2022, and there was no material impacts to the condensed combined financial statements. The FASB issued ASU No. 2016-13, “Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” which introduces guidance for estimating credit losses on certain types of financial instruments based on expected losses and the timing of the recognition of such losses. This guidance becomes effective beginning on January 1, 2023, however, the impact is not expected to be material.
