Risk factors and legal proceedings

The risks ENERGY RESOURCES 12, L.P. names in Item 1A of its 10-K filed Mar 25, 2026: 48 risks under these headings, as written.4

  • Risks Related to the Partnership’s Business, Results of Operations and Cash Flows
  • If oil, natural gas or other hydrocarbon prices decrease and remain depressed for a prolonged period, cash flows from operations will decline and cash available for distributions will be impacted.
  • The Partnership may not have sufficient cash from operations following the establishment of cash reserves and payment of fees and expenses, including cost reimbursements and management fees to the General Partner, to enable the Partnership to make cash distributions to holders of its common units under its cash distribution policy.
  • The Partnership has limited control over the activities on its properties.
  • The Partnership participates in oil and natural gas leases with third parties who may not be able to fulfill their commitments to the Partnership’s projects.
  • The Partnership’s results from operations may be impacted by a lack of geographical diversification.
  • The Partnership depends on oil and natural gas transportation and processing facilities and other assets that are owned by third parties.
  • The Partnership and the operators of its properties may encounter obstacles to marketing the Partnership’s share of oil, natural gas and other hydrocarbons, which could adversely impact the Partnership’s revenues.
  • The Partnership may need additional funding in order to retain its full interest in the Bakken Assets.
  • Property interests that the Partnership has purchased or of which the Partnership participates in the development may not produce as projected and the Partnership may be unable to realize reserve potential, which could adversely affect the Partnership’s cash available for distribution.
  • Compliance with financial and other covenants in the Partnership’s existing or future debt agreements may reduce operational flexibility and create default risk.
  • Ongoing inflationary pressures have resulted in and may result in increases to the costs of goods, services and personnel, and sustained periods of higher costs could reduce the Partnership’s profitability and cash flow.
The other 37 risks
  • Any future hedging transactions in which the Partnership elects to engage will expose it to counterparty credit risk.
  • Hedging activities could result in financial losses or could reduce the Partnership’s net income, which may adversely affect the Partnership’s ability to pay cash distributions to holders of its common units.
  • The Partnership plans to rely on drilling to fully develop the properties the Partnership has acquired. If drilling and well completion are unsuccessful, the Partnership’s cash available for distributions and financial condition will be adversely affected.
  • The Partnership’s business is subject to operational risks that will not be fully insured, which, if they were to occur, could adversely affect the Partnership’s financial condition or results of operations and, as a result, the Partnership’s ability to pay distributions to holders of its common units and service any debt obligations.
  • Risks Related to Investment in the Partnership
  • The Partnership depends on key personnel, the loss of any of whom could materially adversely affect future operations.
  • The common units are not liquid and a limited partner’s ability to resell common units will be limited by the absence of a public trading market and substantial transfer restrictions.
  • Distributions to the Partnership’s common unitholders may not be sourced from its cash generated from operations but from indebtedness, and therefore the Partnership’s distributions during certain periods may exceed earnings and cash flows from operations, and this will decrease the Partnership’s distributions in the future; furthermore, the Partnership cannot guarantee that investors will receive any specific return on their investment.
  • If the General Partner elects to cause the Partnership to make distributions rather than reinvesting the cash flow in its business, the Partnership may be required to sell or farm-out properties or to elect not to participate in exploration or development drilling activities on its properties, which activities could turn out to be profitable.
  • The General Partner is subject to conflicts of interest in operating the Partnership, including conflicts of interest arising out of the General Partner’s ownership of the incentive distribution rights. The Partnership Agreement limits the General Partner’s fiduciary duties to the Partnership in connection with these conflicts of interest.
  • The General Partner has sole responsibility for conducting the Partnership’s business and managing its operations. The General Partner and its affiliates will have conflicts of interest, which may permit them to favor their own interests to the detriment of holders of the Partnership’s common units.
  • Amounts paid to the General Partner, regardless of success of the Partnership’s activities, will reduce the cash the Partnership has available for distribution.
  • Because the General Partner has discretion to determine the amount and timing of any distribution the Partnership may make, there is no guarantee that cash distributions will be paid by the Partnership in any amount or frequency even if its operations generate revenues.
  • The Partnership may be unable to sell its properties, merge with another entity or list the common units on a national securities exchange within its planned timeline or at all.
  • The General Partner may cause the Partnership not to participate with the operator in the drilling of wells on the Partnership’s properties.
  • Fees and cost reimbursements that must be paid to the General Partner and the Dealer Manager will reduce the cash the Partnership has available for distribution.
  • Risks Related to Laws, Regulations, Cybersecurity and Other External Factors
  • The Partnership is subject to complex federal, state, local and other laws and regulations that could adversely affect the cost, manner or feasibility of conducting the Partnership’s operations.
  • Federal and state legislative initiatives and executive orders relating to hydraulic fracturing and oil and natural gas lease sales could result in increased costs and additional operating restrictions or delays, and even could result in the Partnership ceasing business operations.
  • Additional regulatory scrutiny by the EPA could make it difficult to perform hydraulic fracturing, impact the Partnership’s ability to conduct business, and increase the Partnership’s costs of compliance and doing business.
  • The Partnership’s financial condition and results of operations may be materially adversely affected if the Partnership incurs costs and liabilities due to a failure to comply with environmental regulations or a release of hazardous substances into the environment.
  • Climate change legislation or regulations restricting emissions of greenhouse gases, or GHGs, could result in increased operating costs and reduced demand for the oil, natural gas and natural gas liquids the Partnership produces.
  • Significant physical effects of climatic change have the potential to damage the Partnership’s facilities, disrupt the Partnership’s production activities and cause the Partnership to incur significant costs in preparing for or responding to those effects.
  • Cyber-attacks targeting systems and infrastructure used by the oil and natural gas industry may adversely impact the Partnership’s operations.
  • Loss of Partnership information and computer systems could adversely affect the Partnership’s business.
  • Tax Risks to Limited Partners
  • The Partnership’s tax treatment depends on its status as a partnership for U.S. federal income tax purposes and not being subject to a material amount of entity-level taxation by individual states. If the Internal Revenue Service treats the Partnership as a corporation or the Partnership becomes subject to a material amount of entity-level taxation for state tax purposes, it would reduce the amount of cash available for distribution to the Partnership’s limited partners.
  • An IRS contest of the Partnership’s U.S. federal income tax positions may adversely affect the value for the Partnership’s common units, and the cost of any IRS contest will reduce the Partnership’s cash available for distribution to the Partnership’s limited partners.
  • If the IRS makes audit adjustments to the Partnership’s income tax returns, it (and some states) may assess and collect any taxes (including any applicable penalties and interest) resulting from such audit adjustment directly from the Partnership, in which case cash available for distribution to limited partners might be substantially reduced.
  • Tax-exempt entities and foreign persons face unique tax issues from owning common units that may result in adverse tax consequences to them
  • A limited partner may be required to pay taxes on income from the Partnership even if a limited partner did not receive any cash distributions from the Partnership.
  • A limited partner may not qualify for percentage depletion deductions, and even if a limited partner does so qualify, a limited partner will be required to determine, and maintain records supporting, the deduction.
  • The Partnership cannot assure its limited partners that it will meet the requirements for its limited partners to deduct intangible drilling and development costs.
  • If the Partnership is eligible to deduct IDCs, the Partnership cannot assure its limited partners that IDCs will be deductible in any given year.
  • The IRS could challenge the timing of the Partnership’s deductions of IDCs, which could result in an increase to limited partners’ tax liabilities.
  • The ability of a limited partner to deduct its share of our losses and deductions may be limited.
  • Certain federal income tax deductions currently available with respect to oil and natural gas exploration and development may be eliminated as a result of future legislation.
  • Limited partners may be subject to a limit on the ability to deduct interest expense incurred by the Partnership.
  • A limited partner will likely be subject to state and local taxes and tax return filing requirements in states where they do not live as a result of investing in the Partnership’s common units
  • The Partnership may be required to remit federal income taxes to applicable taxing authorities on behalf of its limited partners.

Legal proceedings

The Partnership may be a party to various legal proceedings that arise in the ordinary course of business. At the end of the period covered by this Annual Report on Form 10-K, the Partnership was not a party to any material, pending legal proceedings, or involved in any litigation nor, to management’s knowledge, is any litigation threatened against the Partnership where the outcome would, in management’s judgment based on information currently available to the Partnership, have a material adverse effect on the Partnership’s consolidated financial position or results of operations.
