Material Event (Form 8-K)

Item 8.01. Other Events

To assist trustees and custodians of individual retirement accounts ("IRAs") containing an investment in the Partnership's common units and to assist broker-dealers in meeting their customer account statement reporting obligations under Financial Industry Regulatory Authority ("FINRA") rules for investments in the Partnership, the Partnership is providing an estimated per common unit value of the Partnership's common units as of December 31, 2025 of $11.28 per common unit, as further described below. There can be no assurance that this estimated value per common unit, or the method used to estimate such value, complies with requirements applicable to a trustee's, custodian's or broker-dealer's obligations with respect to IRAs or FINRA's reporting requirements. At December 31, 2025, the Partnership owns an approximate 24% non-operated working interest in 309 producing wells and future possible development sites in the Sanish field located in Mountrail County, North Dakota. The average age of the Partnership's producing wells is approximately 10.2 years.

Methodology

The fair value estimate of the Partnership's common units was based upon a third-party valuation, performed by Pinnacle Energy Services of Oklahoma City, Oklahoma, of the Partnership's oil and natural gas properties and management's estimate of the fair value of the Partnership's other assets and liabilities as of December 31, 2025. The developed per common unit value range is $9.92 - $12.57. The Partnership utilized the mid-point of the assumptions discussed below to determine the estimated value per common unit above. The following is a summary of the details of the fair value estimate:

Since the Partnership's common units are not listed on a national securities exchange, no material public market exists for the Partnership's common units. As a result, although not prepared for generally accepted accounting purposes, the value estimate of the Partnership's oil and gas properties was derived from unobservable inputs and was based on the income approach as outlined in Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 820, Fair Value Measurements and Disclosures. In the income approach, the estimated value of the Partnership's oil and gas properties was calculated from a discounted cash flow model using consolidated projected cash flows of the Partnership's reserves, as well as a discount rate based on market conditions at December 31, 2025. An additional market-based adjustment was made to reflect the probability of successful future development of the Partnership's oil and gas reserves at December 31, 2025. The Partnership's cash and cash equivalents are all highly liquid with maturities of three months or less and the fair market value approximates the carrying value. The Partnership's other assets and liabilities include receivables from the sale of oil, natural gas and natural gas liquids, accounts payable and accrued expenses, which are short-term in nature, and the carrying value of these assets and liabilities approximates fair value at December 31, 2025. The Partnership had no outstanding debt at December 31, 2025. The valuation methodology and calculations were reviewed by management of the Partnership and considered reasonable. The estimated value was not based on an appraisal of the Partnership's assets.

Limitations of the Estimated Value per Common Unit

As with any methodology used to estimate value, the methodology employed by the Partnership was based upon a number of estimates and assumptions that may not be accurate or complete and may not accurately reflect future conditions. The estimates and assumptions underlying the estimated value involve judgments with respect to, among other things, future economic, competitive, regulatory and financial market conditions and future business decisions which may not be realized and that are inherently subject to significant business, economic, competitive and regulatory uncertainties and contingencies, including, among others, risks and uncertainties described in the periodic reports filed by the Partnership with the Securities and Exchange Commission ("SEC"), all of which are difficult to predict and many of which are beyond the control of the Partnership. Further, different parties using different assumptions and estimates could derive a different estimated value per common unit, which could be significantly different from the Partnership's estimated value per common unit.

The estimated per common unit value does not represent: (i) the amount at which the Partnership's common units would trade on a national securities exchange, (ii) the amount a limited partner would obtain if he or she tried to sell his or her common units or (iii) the amount limited partners would receive if the Partnership liquidated its assets and distributed the proceeds after paying all expenses and liabilities. Accordingly, with respect to the estimated value per common unit, the Partnership can give no assurance that:

The estimated value reflects the fact that the estimate was calculated as of a point in time. The value of the Partnership's common units will likely change over time and will be influenced by changes to the value of individual assets, changes in the oil and gas industry, as well as changes and developments in the energy and capital markets. The Partnership does not intend to update or otherwise revise the above information to reflect circumstances existing after the date when made or to reflect the occurrence of future events, even in the event that any or all of the assumptions underlying the information are no longer appropriate.

Assumptions Used in Estimated Value per Common Unit

As discussed above, the estimated value of the Partnership's oil and gas properties was determined based on various market level assumptions, including but not limited to commodity market prices, discount rates and processing and transportation costs. The following is a list of key assumptions used in the calculation of the estimated value of the Partnership's oil and gas properties, a component of the estimated value per common unit:

A change in any of the assumptions would likely produce a different estimated value per common unit. For example:
