Note 1. Partnership Organization Energy Resources 12, L.P. (together with its wholly-owned subsidiary, the “Partnership”) is a Delaware limited partnership formed to acquire producing and non-producing oil and natural gas properties onshore in the United States and to develop those properties. The initial capitalization of the Partnership of $1,000 occurred on December 30, 2016. The Partnership completed its best-efforts offering in October 2019 with a total of approximately 11.0 million common units sold for gross proceeds of $218.0 million and proceeds net of offering costs of $204.3 million. As of June 30, 2026, the Partnership owned an approximate 5% non-operated working interest in 450 producing wells, predominantly in McKenzie, Dunn, McLean and Mountrail counties of North Dakota (collectively, the “Bakken Assets”). The Partnership also owns an estimated approximate 7% non-operated working interest in 12 wells in various stages of the drilling and completion process, and possible future development locations in the Bakken Assets. The Bakken Assets, which are a part of the Bakken shale formation in the Greater Williston Basin, are operated by third-party operators on behalf of the Partnership and other working interest owners. The general partner of the Partnership is Energy Resources 12 GP, LLC (the “General Partner”). The General Partner manages and controls the business affairs of the Partnership. The Partnership’s fiscal year ends on December 31.

Note 2. Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited financial statements have been prepared in accordance with the instructions for Article 10 of SEC Regulation S-X. Accordingly, they do not include all of the information required by generally accepted accounting principles (“GAAP”) in the United States for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. These unaudited financial statements should be read in conjunction with the Partnership’s audited December 31, 2025 financial statements included in its Annual Report on Form 10-K for the year ended December 31, 2025. Operating results for the three and six months ended June 30, 2026 are not necessarily indicative of the results that may be expected for the twelve-month period ending December 31, 2026. Segment Information The Partnership has identified only one reportable business segment, which as a non-operated interest owner of the Bakken Assets, is the production and sale of oil, natural gas and natural gas liquids ("NGLs"). All of the Partnership’s operations and assets are located in North Dakota, and substantially all of its revenues are attributable to United States customers. The operating results of the Partnership’s single reportable segment are evaluated by the General Partner’s Chief Executive Officer, who has been determined to be the Partnership’s Chief Operating Decision Maker (“CODM”), to make key operating decisions, such as the allocation of resources and the evaluation of operating segment performance. The primary measure of profit and loss evaluated by the Partnership’s CODM for its single reportable segment is net income. Net income, total assets and all significant segment expense items are presented in the Partnership’s consolidated financial statements and notes to the consolidated financial statements. Cash and Cash Equivalents Cash and cash equivalents consist of highly liquid investments with original maturities of three months or less. The fair market value of cash and cash equivalents approximates their carrying value. Cash balances may at times exceed federal depository insurance limits. Use of Estimates The preparation of financial statements in conformity with United States GAAP requires management to make estimates and assumptions that affect the reported amounts in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Revenue Recognition The Partnership is bound by a joint operating agreement with the operator of each of its producing wells. Under the joint operating agreement, the Partnership’s proportionate share of production is marketed at the discretion of the operators. The Partnership typically satisfies its performance obligations upon transfer of control of its products and records the related revenue in the month production is delivered to the purchaser. As the Partnership does not operate its properties, it receives actual oil, natural gas, and NGL sales volumes and prices, net of costs incurred by the operators, two to three months after the date production is delivered by the operator. At the end of each month when the performance obligation is satisfied, the variable consideration can be reasonably estimated and amounts due from the Partnership’s operators are accrued in Accounts Receivable and other current assets in the consolidated balance sheets. Variances between the Partnership’s estimated revenue and actual payments are recorded in the month the payment is received; differences have been and are insignificant. As a result, the variable consideration is not constrained. The Partnership has elected to utilize the practical expedient in ASC 606 that states the Partnership is not required to disclose the transaction price allocated to remaining performance obligations if the variable consideration is allocated entirely to a wholly unsatisfied performance obligation. Each delivery of product represents a separate performance obligation; therefore, future volumes are wholly unsatisfied, and disclosure of the transaction price allocated to remaining performance obligations is not required. Virtually all of the Partnership’s contracts’ pricing provisions are tied to a market index, with certain adjustments based on, among other factors, whether a well delivers to a gathering or transmission line, quality of oil, natural gas and natural gas liquids and prevailing supply and demand conditions, so that prices fluctuate to remain competitive with other available suppliers. Accounts Receivable and Concentration of Credit Risk Substantially all of the Partnership’s accounts receivable are due from the operators of the Bakken Assets (the operators have accounts receivable from purchasers of oil, natural gas and NGLs). Oil, natural gas and NGL sales receivables are generally unsecured. This industry and location concentration has the potential to impact the Partnership’s overall exposure to credit risk, in that the purchasers of the Partnership’s oil, natural gas and NGLs and the operators of the properties in which the Partnership has an interest may be similarly affected by changes in economic, industry or other conditions. At June 30, 2026 and December 31, 2025, the Partnership did not reserve for bad debt expense, as all amounts are deemed collectible and the Partnership’s operators do not have a history of non-payment. For the quarter ended June 30, 2026, approximately 92% of the Partnership’s total revenue was generated through sales by five of its operators. All oil and natural gas producing activities of the Partnership are in North Dakota and represent substantially all of the business activities of the Partnership. Income Tax The Partnership is taxed as a partnership for federal and state income tax purposes. Typically, the Partnership has not recorded a provision for income taxes since the liability for such taxes is that of each of the partners rather than the Partnership. In mid-2022, the Partnership was contacted by the state of North Dakota, which asserted that the Partnership has an obligation to make tax payments on behalf of certain non-resident partners. In accordance with its settlements with the state of North Dakota, the Partnership made payments of (i) approximately $365,000 (approximately $0.033 per common unit) in May 2023 for tax year 2021; (ii) approximately $532,000 (approximately $0.048 per common unit) in April 2024 for tax year 2022; (iii) approximately $142,000 (approximately $0.013 per common unit) in April 2024 for tax year 2023; and (iv) approximately $125,000 (approximately $0.011 per common unit) in April 2025 for tax year 2024. The Partnership did not have a required withholding tax payment for tax year 2025. The Partnership’s income tax returns are subject to examination by the federal and state taxing authorities, and changes, if any, could adjust the individual income tax of the partners. The Partnership has evaluated whether any material tax position taken will more likely than not be sustained upon examination by the appropriate taxing authority and believes that all such material tax positions taken are supportable by existing laws and related interpretations. Net Income (Loss) Per Common Unit Basic net income (loss) per common unit is computed as net income (loss) divided by the weighted average number of common units outstanding during the period. Diluted net income (loss) per common unit is calculated after giving effect to all potential common units that were dilutive and outstanding for the period. There were no common units with a dilutive effect for the three and six months ended June 30, 2026 and 2025. As a result, basic and diluted outstanding common units were the same. The Incentive Distribution Rights, as defined below, are not included in net income (loss) per common unit until such time that it is probable Payout (as discussed in Note 8) will occur. Recently Issued Accounting Standards In November 2024, the Financial Accounting Standards Board issued Accounting Standard Update (“ASU”) No. 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. This standard requires that public business entities disclose additional information about specific expense categories in the notes to financial statements at interim and annual reporting periods. This ASU is effective for annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. The Partnership is currently evaluating this ASU to determine its impact on the Partnership’s financial statements and related disclosures.

Each delivery of product represents a separate performance obligation; therefore, future volumes are wholly unsatisfied, and disclosure of the transaction price allocated to remaining performance obligations is not required. Virtually all of the Partnership’s contracts’ pricing provisions are tied to a market index, with certain adjustments based on, among other factors, whether a well delivers to a gathering or transmission line, quality of oil, natural gas and natural gas liquids and prevailing supply and demand conditions, so that prices fluctuate to remain competitive with other available suppliers.

Accounts Receivable and Concentration of Credit Risk Substantially all of the Partnership’s accounts receivable are due from the operators of the Bakken Assets (the operators have accounts receivable from purchasers of oil, natural gas and NGLs). Oil, natural gas and NGL sales receivables are generally unsecured. This industry and location concentration has the potential to impact the Partnership’s overall exposure to credit risk, in that the purchasers of the Partnership’s oil, natural gas and NGLs and the operators of the properties in which the Partnership has an interest may be similarly affected by changes in economic, industry or other conditions. At June 30, 2026 and December 31, 2025, the Partnership did not reserve for bad debt expense, as all amounts are deemed collectible and the Partnership’s operators do not have a history of non-payment. For the quarter ended June 30, 2026, approximately 92% of the Partnership’s total revenue was generated through sales by five of its operators. All oil and natural gas producing activities of the Partnership are in North Dakota and represent substantially all of the business activities of the Partnership.

Income Tax The Partnership is taxed as a partnership for federal and state income tax purposes. Typically, the Partnership has not recorded a provision for income taxes since the liability for such taxes is that of each of the partners rather than the Partnership. In mid-2022, the Partnership was contacted by the state of North Dakota, which asserted that the Partnership has an obligation to make tax payments on behalf of certain non-resident partners. In accordance with its settlements with the state of North Dakota, the Partnership made payments of (i) approximately $365,000 (approximately $0.033 per common unit) in May 2023 for tax year 2021; (ii) approximately $532,000 (approximately $0.048 per common unit) in April 2024 for tax year 2022; (iii) approximately $142,000 (approximately $0.013 per common unit) in April 2024 for tax year 2023; and (iv) approximately $125,000 (approximately $0.011 per common unit) in April 2025 for tax year 2024. The Partnership did not have a required withholding tax payment for tax year 2025. The Partnership’s income tax returns are subject to examination by the federal and state taxing authorities, and changes, if any, could adjust the individual income tax of the partners. The Partnership has evaluated whether any material tax position taken will more likely than not be sustained upon examination by the appropriate taxing authority and believes that all such material tax positions taken are supportable by existing laws and related interpretations.

Net Income (Loss) Per Common Unit Basic net income (loss) per common unit is computed as net income (loss) divided by the weighted average number of common units outstanding during the period. Diluted net income (loss) per common unit is calculated after giving effect to all potential common units that were dilutive and outstanding for the period. There were no common units with a dilutive effect for the three and six months ended June 30, 2026 and 2025. As a result, basic and diluted outstanding common units were the same. The Incentive Distribution Rights, as defined below, are not included in net income (loss) per common unit until such time that it is probable Payout (as discussed in Note 8) will occur.

Recently Issued Accounting Standards In November 2024, the Financial Accounting Standards Board issued Accounting Standard Update (“ASU”) No. 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. This standard requires that public business entities disclose additional information about specific expense categories in the notes to financial statements at interim and annual reporting periods. This ASU is effective for annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. The Partnership is currently evaluating this ASU to determine its impact on the Partnership’s financial statements and related disclosures.

Note 3. Oil and Gas Investments On February 1, 2018, the Partnership completed its first purchase (“Acquisition No. 1”) in the Bakken Assets for approximately $90.5 million, including all closing costs and assumed liabilities. On August 31, 2018, the Partnership completed its second purchase of an additional non-operated working interest in the Bakken Assets for approximately $81.3 million, including all closing costs and assumed liabilities. From September 1, 2017, the effective date of Acquisition No. 1, to June 30, 2026, the Partnership has participated in the drilling of 263 wells, of which 249 have been completed as of June 30, 2026. As of June 30, 2026, the Partnership’s ownership of the Bakken Assets consisted of an approximate 5% non-operated working interest in 450 producing wells. The Partnership incurred approximately $3.2 million and $1.4 million in capital drilling and completion costs for the six-month periods ended June 30, 2026 and 2025, respectively. In October and November 2025, the Partnership elected to participate in the drilling and completion of 12 new wells; the Partnership's share of the estimated capital expenditures for these 12 wells is approximately $9 million. Drilling began on these wells during the fourth quarter of 2025, and approximately $4.8 million in capital costs had been incurred as of June 30, 2026. The Partnership anticipates its operators will complete these wells and turn to sales in the third quarter of 2026. Therefore, the majority of the remaining capital costs are estimated to be incurred through the third quarter of 2026. Since the Partnership is not the operator of any of its oil and natural gas properties, it is difficult to predict the timing of drilling and completion of these wells and their associated capital expenditures. Current estimated capital expenditures could be significantly different from amounts actually invested.

Note 4. Debt On May 2, 2024, the Partnership and its wholly-owned subsidiary, as borrowers, entered into a loan agreement (“Loan Agreement”) with BancFirst (the “Lender”), which provides for a revolving credit facility (“Credit Facility”) with an approved maximum credit amount (“Maximum Credit Amount”) of $20 million, subject to borrowing base restrictions. The Partnership is also subject to an additional fee of 0.50% on any incremental increase to the borrowing base. The Partnership is required to pay an unused facility fee of 0.25% on the unused portion of the Credit Facility, based on borrowings outstanding during a quarter. The Partnership paid one-time commitment and setup fees totaling $100,000 at closing. Total loan costs were approximately $146,000, which were capitalized and to be amortized through the original maturity date of March 1, 2026. On August 8, 2025 ("Effective Date"), the Partnership and its Lender entered into an amendment ("First Amendment") to the Loan Agreement that renewed and extended the Credit Facility for an additional year to March 1, 2027 ("Revised Maturity Date"). Key terms and conditions of the First Amendment include: <table border="0" cellpadding="0" cellspacing="0" style="width: 100%; text-indent: 0px;"><tbody><tr style="vertical-align: top;"><td style="width: 36pt;"> </td><td style="width: 18pt;"> ● </td><td style="width: auto;"> As of the Effective Date, the borrowing base of the Credit Facility was, and remains, $10,000,000. </td></tr> </tbody></table> <table border="0" cellpadding="0" cellspacing="0" style="width: 100%; text-indent: 0px;"><tbody><tr style="vertical-align: top;"><td style="width: 36pt;"> </td><td style="width: 18pt;"> ● </td><td style="width: auto;"> The Partnership paid a loan renewal fee to the Lender associated with the First Amendment of $50,000. </td></tr> </tbody></table> <table border="0" cellpadding="0" cellspacing="0" style="width: 100%; text-indent: 0px;"><tbody><tr style="vertical-align: top;"><td style="width: 36pt;"> </td><td style="width: 18pt;"> ● </td><td style="width: auto;"> The Debt Service Coverage Ratio was amended to be a quarter-based calculation, as opposed to a trailing 12-month calculation that was previously in effect (took effect starting with the quarter ended September 30, 2025). </td></tr> </tbody></table> <table border="0" cellpadding="0" cellspacing="0" style="width: 100%; text-indent: 0px;"><tbody><tr style="vertical-align: top;"><td style="width: 36pt;"> </td><td style="width: 18pt;"> ● </td><td style="width: auto;"> A negative covenant was added that restricts the Partnership’s ability to make future distributions to its limited partners if that said distribution would create an event of default under the Loan Agreement. </td></tr> </tbody></table> Loan costs associated with the First Amendment, which totaled approximately $56,000, were capitalized. In addition, approximately $47,000 of the initial capitalized loan costs had yet to be amortized as of the Effective Date. The application of Accounting Standards Codification 470-50 Debt Modifications and Extinguishments requires the Partnership's unamortized loan costs of $47,000 to be added to the loan costs associated with the First Amendment, so the total of approximately $103,000 in loan costs will be amortized through the Revised Maturity Date. The borrowing base is subject to redetermination semi-annually, on March 1 and September 1, based upon the Lender’s analysis of the Partnership’s proven oil and natural gas reserves. The Lender is also permitted to cause the borrowing base to be redetermined up to two times during a 12-month period. Outstanding borrowings under the Credit Facility cannot exceed the lesser of the borrowing base or the Maximum Credit Amount at any time. The interest rate is equal to the Wall Street Journal Prime Rate plus 0.50%, with a floor of 4.50%. Any further advances under the Credit Facility are to be used to fund capital expenditures for the development of the Partnership’s undrilled acreage. Under the terms of the Loan Agreement, the Partnership may make voluntary prepayments, in whole or in part, at any time with no penalty. The Credit Facility is secured by a mortgage and first lien position on at least 80% of the Partnership’s producing wells. In March 2026, the Partnership and the Lender entered into an amendment ("Second Amendment") to the Loan Agreement that implemented a risk management program to manage the commodity price risk of the Partnership’s future oil and gas production under certain conditions. Under the Second Amendment, the Partnership is not required to enter into future hedging transactions as long as the Partnership maintains a Credit Facility utilization rate of less than or equal to 20% of the Partnership’s PV-9 (defined as the net present value, discounted at 9% per annum) of the Partnership's proved developed producing reserves, as calculated by the Lender during the Lender’s scheduled redeterminations. However, the Partnership must hedge at least 50% of its rolling 12-month projected future production if the Partnership’s utilization of the Credit Facility is greater than 20% but less than or equal to 30% of PV-9, and at least 50% of its rolling 24-month projected future production if the Partnership’s utilization of the Credit Facility is greater than 30% of PV-9. Based on the Partnership’s utilization of the Credit Facility and Lender’s current calculation of PV-9, the Partnership was not subject to any hedging requirements under the amended Loan Agreement as of June 30, 2026. The hedge transactions discussed in Note 7. Derivative Instruments were made at the discretion of the Partnership. The Credit Facility contains prepayment requirements, customary affirmative and negative covenants and events of default. Certain of the financial covenants, inclusive of those within the First Amendment, are: <table border="0" cellpadding="0" cellspacing="0" style="width: 100%; text-indent: 0px;"><tbody><tr style="vertical-align: top;"><td style="width: 36pt;"> </td><td style="width: 18pt;"> ● </td><td style="width: auto;"> A minimum ratio of quarter EBITDAX to debt service coverage of 1.20 to 1.00 </td></tr> <tr style="vertical-align: top;"><td style="width: 36pt;"> </td><td style="width: 18pt;"> ● </td><td style="width: auto;"> A minimum ratio of current assets to current liabilities of 1.00 to 1.00 </td></tr> </tbody></table> The Partnership was not in compliance with its debt service coverage ratio as defined within the Loan Agreement at March 31, 2025 and June 30, 2025; the Lender waived these covenant calculations for those quarters. The Partnership has been in compliance with its financial covenants for each quarter since. If the Partnership is not in compliance with its covenants in future periods, the Partnership cannot provide any assurance or guarantee that covenant compliance waivers will be granted in future periods. If the Partnership is not able to obtain waivers, either (a) the Credit Facility may not be available for the Partnership’s use or (b) an outstanding balance under the Credit Facility may become due on demand at that time. The Partnership was in compliance with its financial covenants at June 30, 2026. The outstanding balance on the Credit Facility was $5.8 million at both June 30, 2026 and December 31, 2025, and the interest rate was 7.25% for both periods. At June 30, 2026 and December 31, 2025, the outstanding balance on the Credit Facility approximated the fair market value of the Credit Facility. The Partnership estimated the fair value of its credit facility by discounting the future cash flows of the instrument at estimated market rates consistent with the maturity of a debt obligation with similar credit terms and credit characteristics, which are Level 3 inputs under the fair value hierarchy. Market rates take into consideration general market conditions and maturity.

Note 5. Asset Retirement Obligations The Partnership records an asset retirement obligation (“ARO”) and capitalizes the asset retirement costs in oil and natural gas properties in the period in which the asset retirement obligation is incurred based upon the fair value of an obligation to perform site reclamation, dismantle facilities or plug and abandon wells. After recording these amounts, the ARO is accreted to its future estimated value using an assumed cost of funds and the additional capitalized costs are depreciated on a unit-of-production basis. Inherent in the present value calculation are numerous assumptions and judgments including the ultimate settlement amounts, inflation factors, credit-adjusted discount rates, timing of settlement and changes in the legal, regulatory, environmental and political environments. To the extent future revisions of these assumptions impact the present value of the existing asset retirement obligation, a corresponding adjustment is made to the oil and natural gas property balance. The changes in the aggregate ARO are as follows: <table border="0" cellpadding="0" cellspacing="0" class="finTable" style="border-collapse: collapse; width: 100%; font-size: 10pt; font-family: "Times New Roman", Times, serif;

Note 6. Fair Value of Financial Instruments The Partnership follows authoritative guidance related to fair value measurement and disclosure, which establishes a three-level valuation hierarchy for disclosure of fair value measurements. The valuation hierarchy categorizes assets and liabilities measured at fair value into one of three different levels depending on the observability of the inputs employed in the measurement using market participant assumptions at the measurement date. Categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The three levels are defined as follows: <table border="0" cellpadding="0" cellspacing="0" style="width: 100%; text-indent: 0px;"><tbody><tr style="vertical-align: top;"><td style="width: 36pt;"> </td><td style="width: 18pt;"> ● </td><td style="width: auto;"> Level 1: Quoted prices in active markets for identical assets </td></tr> <tr><td style="width: 36pt;"> </td><td style="width: 18pt;"> ● </td><td style="width: auto;"> Level 2: Significant other observable inputs – inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, either directly or indirectly, for substantially the full term of the financial instrument </td></tr> <tr style="vertical-align: top;"><td style="width: 36pt;"> </td><td style="width: 18pt;"> ● </td><td style="width: auto;"> Level 3: Significant unobservable inputs </td></tr> </tbody></table> The Partnership’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and the consideration of factors specific to the asset or liability. The Partnership’s policy is to recognize transfers in or out of a fair value hierarchy as of the end of the reporting period for which the event or change in circumstances caused the transfer. The Partnership has consistently applied the valuation techniques discussed above for all periods presented. During the three and six months ended June 30, 2026, there were no transfers in or out of Level 1, Level 2, or Level 3 assets and liabilities measured on a recurring basis. 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 following table sets forth by level within the fair value hierarchy the Partnership’s financial assets and liabilities that were accounted for at fair value on a recurring basis as of June 30, 2026. <table border="0" cellpadding="0" cellspacing="0" class="finTable" style="width: 100%;

The fair value of the Partnership’s derivative financial instruments is determined based upon future prices, volatility and time to maturity, among other things. Counterparty statements are utilized to determine the value of the commodity derivative instruments and are reviewed and corroborated using various methodologies and significant observable inputs. The fair value of the commodity derivatives noted above are included in the Partnership’s consolidated balance sheet at June 30, 2026. See additional detail in Note 7. Derivative Instruments. Fair Value of Other Financial Instruments The carrying value of the Partnership’s other financial instruments, including cash and cash equivalents, accounts receivable, accounts payable and accrued expenses, reflect these items’ cost, which approximates fair value based on the timing of the anticipated cash flows, current market conditions and short-term maturity of these instruments.

Note 7. Derivative Instruments Participation in the oil and natural gas industry exposes the Partnership to risks associated with potentially volatile changes in energy commodity prices, and therefore, the Partnership’s future earnings are subject to these risks. Therefore, the Partnership periodically utilizes derivative contracts to manage the commodity price risk on the Partnership’s future production it will produce and sell and to reduce the effect of volatility in commodity price changes to provide a base level of cash flow from operations. In March 2026, the Partnership entered into costless collar derivative contracts to mitigate the commodity price risk for a portion of the Partnership's expected oil production for the period from April 2026 to December 2026. The Partnership generally uses costless collar derivative contracts, which establish floor and ceiling prices on future anticipated production. The Partnership did not pay or receive a premium related to the costless collars into which it entered, and the contracts will be settled monthly. As of June 30, 2026, the Partnership’s derivative instruments were in an asset position. The Partnership recognized total assets of approximately $0.5 million, which has been recorded as Derivative asset on the Partnership’s consolidated balance sheet as of June 30, 2026. The Partnership did not designate its derivative instruments as hedges for accounting purposes and did not enter into such instruments for speculative trading purposes. As a result, when derivatives do not qualify or are not designated as a hedge, the changes in the fair value are recognized on the Partnership’s consolidated statements of operations as a gain or loss on derivative instruments. The following table presents the settlement losses of matured derivative instruments and non-cash mark-to-market gains for the periods presented. <table border="0" cellpadding="0" cellspacing="0" class="finTable" style="width: 100%;

The ISDA may provide that as a result of certain circumstances, such as cross-defaults, a counterparty may require all outstanding derivative instruments under an ISDA to be settled immediately. The Partnership has netting arrangements with its counterparties that provide for offsetting payables against receivables from separate derivative instruments. The use of derivative instruments involves the risk that the Partnership’s counterparty will be unable to meet the financial terms of such instruments.

Note 8. Capital Contribution and Partners’ Equity At inception, the General Partner and organizational limited partner made initial capital contributions totaling $1,000 to the Partnership. Upon closing of the minimum offering, the organizational limited partner withdrew its initial capital contribution of $990, the General Partner received Incentive Distribution Rights (defined below), and has been reimbursed for its documented third-party out-of-pocket expenses incurred in organizing the Partnership and offering the common units. The Partnership completed its best-efforts offering of common units as of the close of business on October 24, 2019. As of the conclusion of the offering, the Partnership had completed the sale of approximately 11.0 million common units for total gross proceeds of $218.0 million and proceeds net of offering costs of $204.3 million. Under the agreement with David Lerner Associates, Inc. (the “Managing Dealer”), the Managing Dealer received a total of 6% in selling commissions and a marketing expense allowance based on gross proceeds of the common units sold. The Managing Dealer also has Dealer Manager Incentive Fees (defined below) where the Managing Dealer could receive distributions up to an additional 4% of gross proceeds of the common units sold in the Partnership’s best-efforts offering as outlined in the prospectus based on the performance of the Partnership. Based on the common units sold in the best-efforts offering, the Dealer Manager Incentive Fees are approximately $8.7 million, subject to Payout (defined below). Prior to “Payout,” which is defined below, all of the distributions made by the Partnership, if any, will be paid to the holders of common units. Accordingly, the Partnership will not make any distributions with respect to the Incentive Distribution Rights or the Dealer Manager Incentive Fees to the Managing Dealer until Payout occurs. The Agreement of Limited Partnership of the Partnership (the “Partnership Agreement”) provides that “Payout”, which is defined below, occurs on the day when the aggregate amount distributed with respect to each of the common units equals $20.00 plus the Payout Accrual. The Partnership Agreement defines “Payout Accrual” as 7% per annum simple interest accrued monthly until paid on the Net Investment Amount outstanding from time to time. The Partnership Agreement defines Net Investment Amount initially as $20.00 per common unit, regardless of the amount paid for the common unit. If at any time the Partnership distributes to holders of common units more than the Payout Accrual, the amount the Partnership distributes in excess of the Payout Accrual will reduce the Net Investment Amount. In June 2023, the General Partner declared and paid a special distribution to return $1.60 per common unit of capital to holders of Partnership common units. As described in Income Tax in Note 2. Summary of Significant Accounting Policies, in May 2023, April 2024 and April 2025, the Partnership paid total withholding taxes of approximately $0.11 per common unit to the state of North Dakota on behalf of its limited partners related to tax years 2021 through 2024. These withholding tax payments, along with the $1.60 per common unit special distribution to holders of its common units in June 2023, have reduced the Net Investment Amount described above by an approximate total of $1.71 per common unit. All distributions made by the Partnership after Payout, which may include all or a portion of the proceeds of the sale of all or substantially all of the Partnership’s assets, will be made as follows: <table border="0" cellpadding="0" cellspacing="0" style="width: 100%; text-indent: 0px;"><tbody><tr style="vertical-align: top;"><td style="width: 36pt;"> </td><td style="width: 18pt;"> ● </td><td style="width: auto;"> First, (i) to the Record Holders of the Incentive Distribution Rights, 30%; (ii) to the Managing Dealer, the “Dealer Manager Incentive Fees”, 30%, until such time as the Managing Dealer receives 4% of the gross proceeds of the common units sold; and (iii) to the Record Holders of outstanding common units, 40%, pro rata based on their percentage interest. </td></tr> </tbody></table> <table border="0" cellpadding="0" cellspacing="0" style="width: 100%; text-indent: 0px;"><tbody><tr style="vertical-align: top;"><td style="width: 36pt;"> </td><td style="width: 18pt;"> ● </td><td style="width: auto;"> Thereafter, (i) to the Record Holders of the Incentive Distribution Rights, 60%; and (ii) to the Record Holders of outstanding common units, 40%, pro rata based on their percentage interest. </td></tr> </tbody></table> All items of income, gain, loss and deduction will be allocated to each Partner’s capital account in a manner generally consistent with the distribution procedures outlined above. In July 2025, the General Partner elected to suspend distributions to Partnership limited partners. The Partnership accumulates unpaid distributions based on an annualized return of seven percent (7%), and all accumulated unpaid distributions are required to be paid before final Payout occurs, as defined above. As of June 30, 2026, the unpaid Payout Accrual, for the period from July 2025 to June 2026, totaled approximately $1.30 per common unit, or approximately $14 million. For the three and six months ended June 30, 2025, the Partnership paid distributions $0.320541 per common unit and $0.641082 per common unit, or $3.5 million and $7.1 million, respectively.

Note 9. Related Parties The Partnership has, and is expected to continue to engage in, significant transactions with related parties. These transactions cannot be construed to be at arm’s length and the results of the Partnership’s operations may be different than if conducted with non-related parties. The General Partner’s Board of Directors oversees and reviews the Partnership’s related party relationships and is required to approve any significant modifications to any existing related party transactions, as well as any new significant related party transactions. The Partnership will reimburse the General Partner for any costs incurred by the General Partner for certain expenses, which include costs for organizing the Partnership, costs incurred in the offering of the common units and general and administrative costs. The Partnership also agreed to pay the General Partner an advisory fee to manage the day-to-day affairs of the Partnership, including serving as an investment advisor and consultant in connection with the acquisition, development, operation and disposition of oil and gas properties and other assets of the Partnership. In accordance with the Partnership Agreement, subsequent to the Partnership’s first asset purchase, which occurred on February 1, 2018, the Partnership is required to pay quarterly an annual fee of 0.5% of the total gross equity proceeds raised by the Partnership in its best-efforts offering. The management fee that has been paid to the General Partner for the three and six months ended June 30, 2026 and 2025 was approximately $273,000 and $545,000 in both periods, and is included in General and administrative expenses on the consolidated statements of operations. For the three and six months ended June 30, 2026, approximately $83,000 and $170,000 of general and administrative costs, respectively, were incurred by a member of the General Partner and will be reimbursed by the Partnership. At June 30, 2026, approximately $83,000 was due to a member of the General Partner and is included in Accounts payable and accrued expenses in the consolidated balance sheets. For the three and six months ended June 30, 2025, approximately $78,000 and $167,000 of general and administrative costs were incurred by a member of the General Partner and have been reimbursed by the Partnership.
