Risk factors and legal proceedings

The risks Gulf Coast Ultra Deep Royalty Trust names in Item 1A of its 10-K filed Mar 25, 2026: 26 risks under these headings, as written.17

  • Risks Related to Operations
  • Production risks can adversely affect distributions from the Royalty Trust.
  • The value of the Royalty Trust units is uncertain.
  • Future Royalty Trust distributions are uncertain because the Royalty Trust does not control the operations of the subject interests and any royalties received must exceed administrative expenses, any indebtedness and a minimum cash requirement.
  • Natural gas prices fluctuate due to a number of factors that are beyond the control of the Royalty Trust and HOGA, and lower prices could reduce proceeds to the Royalty Trust and cash distributions to Royalty Trust unitholders.
  • The onshore Highlander subject interest targets Inboard Lower Tertiary/Cretaceous formations onshore in South Louisiana, which has greater risks and costs associated with its exploration and development than conventional prospects.
  • The Royalty Trust is vulnerable to risks associated with operations onshore in South Louisiana because the onshore Highlander subject interest is located in this area.
  • Risks Related to Environmental Conditions
  • Climate change laws and regulations restricting emissions of greenhouse gases could result in increased operating costs and reduced demand for the oil and natural gas that HOGA produces while the physical effects of climate change could disrupt their production and cause it to incur significant costs in preparing for or responding to those effects.
  • Risks Related to Ownership of the Royalty Trust Units
  • There is a limited public market for the Royalty Trust units, which could affect the market price, trading volume, liquidity and resale price of the Royalty Trust units.
  • “Penny Stock” rules may make buying or selling the Royalty Trust units difficult.
The other 17 risks
  • FINRA sales practice requirements may also limit a Royalty Trust unitholder’s ability to buy and sell royalty trust units.
  • Risks Related to the Royalty Trust Structure
  • The Royalty Trust is dependent on HOGA for funding unless royalty income from production on the onshore Highlander subject interest is sufficient to cover the Royalty Trust’s administrative expenses.
  • HOGA’s interests and the interests of the Royalty Trust unitholders may not always be aligned.
  • HOGA may at any time transfer all or part of the onshore Highlander subject interest and will not have control or influence over the activities related to the subject interests it does not operate.
  • The Royalty Trust is limited in duration, may be dissolved upon certain events and the Royalty Trust units are subject to call features.
  • The Royalty Trust is passive in nature and neither the Royalty Trust nor the Royalty Trust unitholders have any ability to influence HOGA or to control the development or operation of the onshore Highlander subject interest.
  • HOGA or FCX may sell Royalty Trust units in the public or private markets, and any such sales may have a material adverse effect on the trading price of the Royalty Trust units.
  • The Royalty Trust is managed by a Trustee who cannot be replaced except by a majority vote of the Royalty Trust unitholders, which may make it difficult for Royalty Trust unitholders to remove or replace the Trustee.
  • Financial information of the Royalty Trust is not prepared in accordance with GAAP.
  • The Royalty Trust is a smaller reporting company and benefits from certain reduced governance and disclosure requirements, including that the Royalty Trust’s independent registered public accounting firm is not required to, nor were they engaged to, attest to the effectiveness of the Royalty Trust’s internal control over financial reporting. The Royalty Trust cannot be certain if the omission of reduced disclosure requirements applicable to smaller reporting companies will make the Royalty Trust units less attractive to investors.
  • Risks Related to Cybersecurity
  • Cybersecurity incidents or other failures in telecommunications or information technology systems could result in information theft, data corruption and significant disruption of the respective operations of the Trustee and HOGA as they relate to the Royalty Trust.
  • Risks Related to Taxes
  • The tax treatment of the Royalty Trust units is uncertain.
  • Royalty Trust unitholders should consult their tax advisors as to the specific tax consequences of the ownership and disposition of the Royalty Trust units, including the applicability and effect of U.S. federal, state, local and foreign income and other tax laws in light of their particular circumstances.
  • The Royalty Trust has not requested a ruling from the IRS regarding the tax treatment of ownership of the Royalty Trust units. If the IRS were to determine (and be sustained in that determination) that the Royalty Trust is not a “grantor trust” for federal income tax purposes, or that the overriding royalty interests are not properly treated as mineral royalty interests for U.S. federal income tax purposes, the Royalty Trust unitholders may receive different and potentially less advantageous tax treatment.
  • The availability and extent of percentage depletion deductions to the Royalty Trust unitholders for any taxable year is uncertain.
  • Royalty Trust unitholders will be required to pay taxes on their pro-rata share of the taxable income attributable to the assets of the Royalty Trust even if they do not receive any cash distributions from the Royalty Trust.
  • As a consequence of special reporting rules, Royalty Trust unitholders may not be able to recognize income/claim losses realized by the Royalty Trust until the unitholders dispose of Royalty Trust units.
