What it owns

What MARINE PETROLEUM TRUST reports owning in its annual reports to the SEC: buildings, land and equipment, real estate and locations, investments, intangible assets and inventory, at the end of its latest fiscal year and a year before.

Properties, in its own words

General. Marine is not engaged in oil and natural gas exploration or production operations, and its only industry segment or purpose is the administration and collection of royalties. Marine’s income is based upon the oil and natural gas operations of third parties. Marine’s income is derived from contracts that provide for payments in the nature of overriding royalties made to Marine based on oil and natural gas sales from certain leases in the Gulf of America. Marine does not own or directly lease any physical properties.

Reserves. As indicated above, Marine is not engaged in the exploration or production of oil or natural gas. Marine’s income is derived from overriding royalty payments that are carved out of working interests in oil and natural gas leases in the Gulf of America. Marine does not have the engineering data necessary to make an estimate of the proved oil and natural gas reserves attributable to such working interests (nor the present value of future net cash flows from such reserves), and Marine is not entitled to receive such data from the owners of the working interests from which its interests are derived. See also “Item 2. Properties — Difficulty in Obtaining Certain Data.” Since Marine does not have access to this reserve information, Marine is unable to compute the standardized measure of discounted future net cash flows attributable to such working interests.

The rest of Item 2

Marine did not file any reports during the fiscal year ended June 30, 2026, with any U.S. federal authority or agency with respect to oil and natural gas reserves.

Due to the nature of Marine’s business, it does not have any delivery commitments.

Production. The following table includes information regarding the net quantities of oil, natural gas, and natural gas liquids sold with respect to Marine’s overriding royalty interests for each of the last three fiscal years, as well as the average sales price per unit of oil, natural gas, and natural gas liquids sold upon which payments to Marine are based.

2026 · 2025 · 2024

Net quantities sold:

Oil (in barrels [“bbls”]) · 14,076 · 12,706 · 12,805

Natural gas (in thousands of cubic feet [“mcf”]) · 16,328 · 19,524 · 11,399

Natural gas liquids (in thousands of cubic feet [“mcf”]) · 30,519 · 35,183 · 20,339

Average sales price for royalty oil and natural gas sold:

Oil (per bbl) (1) · 63.88 · 74.63 · 76.54

Natural gas, net of expenses (per mcf) (1) · 3.56 · 2.41 · 0.92

Natural gas liquids, net of expenses (per mcf) (1) · 0.31 · 0.45 · 0.16

The average sales price is calculated from data provided by the operators.

Information about average production cost (lifting cost) per unit of production has been omitted due to its unavailability and inapplicability to Marine. For more recent information regarding prices, see “Item 7. Trustee’s Discussion and Analysis of Financial Condition and Results of Operations.”

Productive Wells. Marine has performed a review of public records from the Bureau of Ocean Energy Management, Regulation and Enforcement (“BOEM”), a division of the U.S. government, and Marine's revenue records provided by the operators. Based on this information, Marine believes there are approximately 69 gross active wells subject to Marine’s interests. Marine believes that the term “active wells” is synonymous with the term “productive wells” as defined in Item 1205 of Regulation S-K. While Marine believes that most of the active wells produce both oil and natural gas, Marine is unable to determine the actual number of wells classified as either oil or natural gas wells without unreasonable effort and expense. See “Item 2. Properties — Difficulty in Obtaining Certain Data.”

Drilling Activity. Based on information from BOEM, revenue records from remitters received by Marine, and other information from a third-party, which has access to records from other public sources, Marine believes there were no wells drilled or recompleted in which Marine had an interest during the fiscal year 2026. Using these same sources, the Trust believes there were no wells drilled or recompleted in which Marine had an interest during fiscal year 2025.

Information regarding net wells or acres is not included since Marine does not own any working interests.

Lease Acreage. Marine has performed a review of the public records from BOEM and Marine's revenue records provided by the operators. Based on this information, Marine believes that as of June 30, 2026, Marine had an overriding royalty interest in 17 different oil and natural gas leases covering an aggregate of 77,646 gross acres. The lease acreage is all located in federal waters in the Central and Western areas of the Gulf of America off the coasts of Louisiana and Texas.

Leases are typically granted for a term of five years, during which the lease owner must establish commercial production, or the lease expires. Marine’s overriding royalty area is determined by a contract that defines the area in which Marine is entitled to receive a royalty interest. In some cases, that area does not cover an entire lease block. In those cases, Marine’s royalty interest only applies to the area that lies within the lease. Of the aggregate of 77,646 total gross acres in which Marine has an overriding royalty interest, there are 210 gross acres located on leases that have commercial production, but the production is not on Marine’s overriding royalty area within those leases.

The overriding royalty interest owned by Marine is three-fourths of 1% of the working interest held by the Interest Owners. The fractional interest therefore varies from lease to lease.

Risk factors and legal proceedings

The risks MARINE PETROLEUM TRUST names in Item 1A of its 10-K filed Sep 25, 2026: 21 risks under these headings, as written.3

  • Risks related to the Trust’s Business and its Industry
  • Current and future oil and natural gas prices fluctuate due to a number of uncontrollable factors. Any depression in oil and natural gas prices would result in lower royalty payments to Marine and lower cash distributions to its unitholders.
  • Marine is unable to acquire royalty interests in any more leases.
  • Royalty interests are depleting assets and may deplete faster than expected or in their entirety.
  • Pandemics or other public health concerns, such as COVID-19, or the novel coronavirus, and any measures taken to mitigate such health concerns, could adversely affect the business and operations of the operators, which in turn could have an adverse effect on Trust distributions.
  • The operators of the oil and natural gas leases are subject to extensive governmental regulation.
  • The owner of any properties in the leases may transfer any of the properties to another unrelated third party, which could reduce the amount of royalty payments that are received.
  • The owner of any properties in the leases may abandon any property, terminating the related royalty interest Marine may hold.
  • The Trustee, Marine and the Trust’s unitholders do not control the operation or development of the properties in the leases and have little influence over their operation or development.
  • Risks Related to the Units
  • The market price for the units may not reflect the value of the royalty interests held by Marine.
  • Our units have been thinly traded and an active trading market for our units may not develop.
The other 11 risks
  • Operating risks for the working interest owners’ interests on the leases can adversely affect distributions.
  • Failure to collect royalty payments from working interest owners could adversely affect Marine’s distributions to its unitholders.
  • Marine’s royalty interest can be sold and the Trust can be terminated.
  • Important reserve and other information with respect to the particular leases subject to Marine’s royalty interest is unreasonably difficult to obtain.
  • The Trustee may be subject to attempted cybersecurity disruptions from a variety of sources including state-sponsored actors.
  • Terrorism and continued geopolitical hostilities, including the war in Eastern Europe and the Middle East, could adversely affect Marine’s distributions to its unitholders or the market price of its units.
  • Unitholders have limited voting rights.
  • The limited liability of the unitholders is uncertain.
  • Cash held by the Trustee is not insured by the Federal Deposit Insurance Corporation.
  • Financial information of Marine is not prepared in accordance with generally accepted accounting principles in the United States.
  • If the Trust becomes subject to the Texas franchise tax, the Trustee may have to withhold amounts from future distributions to pay the tax liability.
