Marine Petroleum Trust is a royalty trust created in 1956, holding overriding royalty interests in oil and natural gas leases located offshore in the Gulf of America (Texas and Louisiana). The Trust is administered by Argent Trust Company. It does not engage in business operations; income is derived solely from royalties paid by working interest owners (primarily Chevron and its assignees). The Trust is scheduled to expire on June 1, 2041, unless extended.

Key Financial Metrics

Material Changes vs. Prior Period

The Trust experienced a significant decline in financial performance compared to the prior year quarter:

• Revenue Decline: Total income decreased by approximately 26% ($78,790), driven primarily by a 24% drop in oil and natural gas royalties.
• Price and Volume Impact:
  • Oil: Average price realized dropped from $81.11/bbl to $63.52/bbl. Production volumes slightly decreased from 3,265 bbls to 3,226 bbls.
  • Natural Gas: Volumes sold decreased significantly from 5,095 mcf to 3,567 mcf, though the average net price increased slightly from $3.02 to $3.14 per mcf.
  • Natural Gas Liquids (NGL): Volumes decreased from 8,437 mcf to 6,290 mcf, and the average price fell from $0.75 to $0.38 per mcf.
• Expense Increase: General and administrative expenses rose by 35% ($23,949), attributed to the timing of professional fee payments.
• Trust Corpus: The Trust corpus decreased from $921,527 to $916,146 due to distributions exceeding distributable income for the period.

Outlook, Risks, and Management Commentary

Management Commentary: The Trustee notes that income and distributions are heavily influenced by commodity prices and production volumes, which are beyond the Trust's control. The Trust operates on a modified cash basis, recognizing royalty income when received. No new accounting pronouncements significantly impact the Trust.

Risks and Contingencies:

• Depleting Assets: The Trust holds depleting assets with no ability to invest in new properties or replace reserves. Production is expected to decrease over time due to natural well depletion.
• Commodity Price Volatility: Future income is uncertain due to fluctuations in oil and gas prices driven by global economic conditions, geopolitical events, and supply/demand dynamics.
• Lease Expiration: Leases are typically granted for five-year terms. If commercial production is not established or maintained, leases may expire, terminating royalty rights.
• Third-Party Dependence: The Trust relies entirely on working interest owners for production, marketing, and royalty calculations.

Guidance: The filing contains no specific forward-looking financial guidance or projections for future quarters, citing the inability to predict commodity prices or production levels.

Key Facts for Investor Verification

• Depletion Risk: Verify the remaining life of the 19 active leases and the specific production decline rates of the underlying wells.
• Commodity Exposure: Confirm current market prices for oil, natural gas, and NGLs relative to the Trust's historical average realizations ($63.52/bbl for oil in Q3 2025).
• Expense Timing: Monitor general and administrative expenses, as the Q3 2025 increase was driven by payment timing rather than a structural cost increase.
• Trust Corpus vs. Distributions: Note that distributions ($0.07/unit) exceeded distributable income ($0.07/unit) slightly in terms of total cash flow mechanics, drawing down the corpus reserve ($136,194 distributed vs. $130,813 income).
• Lease Status: Review the status of the 87,646 gross acres to ensure no critical leases are approaching expiration without commercial production.
