ITEM 9A. CONTROLS AND PROCEDURES Effectiveness of Disclosure Controls and Procedures As of June 30, 2022, the Trustee carried out an evaluation of the effectiveness of the design and operation of the Trust’s disclosure controls and procedures pursuant to Rules 13a-15(e) and 15d-15(e) of the Exchange Act. Based upon that evaluation, the Trustee concluded that Marine’s disclosure controls and procedures were effective as of June 30, 2022. Changes in Internal Control Over Financial Reporting There have not been any changes in Marine’s internal control over financial reporting during the fourth quarter of fiscal 2022 that have materially affected, or are reasonably likely to materially affect, Marine’s internal control over financial reporting. Trustee’s Report on Internal Control Over Financial Reporting The Trustee is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rule 13a-15(f) or Rule 15d-15(f) under the Exchange Act. The Trustee conducted an evaluation of the effectiveness of Marine’s internal control over financial reporting based on the criteria established in “Internal Control-Integrated Framework” issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on the Trustee’s evaluation under the “Internal Control-Integrated Framework,” the Trustee concluded that Marine’s internal control over financial reporting was effective as of June 30, 2022. This Annual Report on Form 10-K does not include an attestation report of Marine’s registered public accounting firm regarding internal control over financial reporting since the Trustee’s report was not subject to attestation by Marine’s registered public accounting firm pursuant to an exemption for smaller reporting companies pursuant to Section 404(c) of the Sarbanes-Oxley Act of 2002.

FORM 10-K SUMMARY None. 19 Table of Contents REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Trustee and Unitholders of Marine Petroleum Trust and Subsidiary Opinion on the Consolidated Financial Statements We have audited the accompanying consolidated statements of assets, liabilities, and trust corpus of Marine Petroleum Trust and Subsidiary (the Trust) as of June 30, 2022 and 2021, and the related consolidated statements of distributable income and changes in trust corpus for each of the two years in the period ended June 30, 2022, and the related notes (collectively referred to as the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the assets, liabilities, and trust corpus of the Trust as of June 30, 2022 and 2021, and the distributable income and changes in trust corpus for each of the two years in the period ended June 30, 2022, in conformity with the modified cash basis of accounting, which is a comprehensive basis of accounting other than accounting principles generally accepted in the United States of America. As described in Note 2 to the consolidated financial statements, these consolidated financial statements were prepared on a modified cash basis of accounting, which is a comprehensive basis of accounting other than accounting principles generally accepted in the United States of America. Basis for Opinion These consolidated financial statements are the responsibility of the Trustee. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Trust in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Trust is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the entity’s internal control over financial reporting. Accordingly, we express no such opinion. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by the Trustee, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion. Critical Audit Matters Critical audit matters are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the Trustee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. We determined that there are no critical audit matters. /s/ WEAVER AND TIDWELL, L.L.P We have served as the Trust’s auditor since 2011.

The contract rights entitled the Trust to receive an overriding royalty interest in oil, natural gas and other mineral leasehold interests acquired by Gulf Oil Corporation, now Chevron U.S.A., Inc. (“Chevron”), a subsidiary of Chevron Corporation, in certain areas of the Gulf of Mexico prior to January 1, 1980. The Trust must distribute to its unitholders all cash accumulated each quarter, less an amount reserved for accrued liabilities and estimated future expenses. The Trust and its subsidiary cannot engage in a trade or business. Funds held by Marine Petroleum Corporation, a wholly owned subsidiary of the Trust, (“MPC,” and collectively with the Trust, “Marine”) pending distribution to the Trust are invested in U.S. Treasury and agency bonds. The unitholders assigned their contract rights offshore of Louisiana to MPC reserving a 98% net profits interest to themselves. The net profits interest contract was transferred to the Trust along with the other properties. The Trust is authorized to pay expenses of MPC should it be necessary. The Trust is to continue until June 1, 2041, or until such later date as holders of the units owning a majority of the outstanding units may designate, but in any event, not more than 20 years from such designation. However, the unitholders owning eighty percent (80%) or more of the outstanding units may terminate the Trust on any date. (b) Principles of Consolidation The consolidated financial statements include the Trust and its wholly owned subsidiary, MPC. All material intercompany accounts and transactions have been eliminated upon consolidation. (c) Producing Oil and Gas Properties At the time the Trust was established, no determinable market value was available for the assets transferred to the Trust; consequently, nominal values were assigned. Accordingly, no allowance for depletion has been included. All income from oil and natural gas royalties relate to proved developed oil and natural gas reserves. (d) U.S. Federal Income Taxes No provision has been made for U.S. Federal income taxes on the Trust’s income since such taxes are the liability of the unitholders. U.S. Federal income taxes have been provided on the income of MPC (which specifically excludes the 98% net profits interest to be retained by and delivered to the Trust), after deducting statutory depletion. MPC uses the cash method of reporting for U.S. Federal income taxes. The primary difference between the actual tax expense of MPC and the expected tax expense is due to the fact that only 2% of MPC’s income ( i.e. , excluding the 98% net profits interest retained by, and delivered to, the Trust) is subject to U.S. Federal income tax. Tax positions taken by the Trust related to the Trust’s pass-through status and federal state tax positions have been reviewed, and the Trustee is of the opinion that material positions taken would more likely than not be sustained upon an examination. In accordance with the Trust’s basis of accounting discussed in Note 2, the Trust would only recognize the impact of tax positions that were not upheld at the time of payment. As of June 30, 2022, the Trust’s tax years 2017 through 2021 remain subject to examination. 24 Table of Contents MPC recognizes interest and penalties related to unrecognized tax benefits in income tax expense. (e) Credit Risk Concentration and Cash Equivalents Financial instruments which potentially subject Marine to concentrations of credit risk are primarily investments in cash equivalents, U.S. Treasury and agency bonds. The Trust and MPC place their cash investments with financial institutions or companies that the Trustee considers credit worthy and limit the amount of credit exposure from any one financial institution. Marine had cash and cash equivalents of $1,154,136 and $902,023 at June 30, 2022 and 2021, respectively, which consisted of cash deposits, U.S. Treasury and agency bonds and money market accounts. (f) Use of Estimates The preparation of financial statements in conformity with the modified cash basis method of accounting requires the Trustee to make various estimates and assumptions that affect the reported amount of liabilities at the date of the financial statements and the reported amount of expenses during the reporting period. Actual results may differ from such estimates. (g) Distributable Income per Unit and Distributions Distributable income per unit is determined by dividing distributable income by the number of units of beneficial interest outstanding during the period. Distributions to unitholders are calculated and paid out net of reserve for future expenses, which are estimated by the Trustee on a quarterly basis. (h) Significant Royalty Sources Percent of royalty revenue received by Marine from producers is summarized as follows: Fiscal Year Ended June 30, Company 2022 2021 2020 Arena Energy, LP 99 % 99 % 96 % Chevron USA, Inc. 0 % 1 % 1 % Fieldwood Energy LLC 0 % 0 % 3 % Walter Oil & Gas Corporation 1 % 0 % 0 % 100 % 100 % 100 % (2) Basis of Accounting The financial statements of Marine have been prepared on the modified cash basis method and are not intended to present financial position and results of operations in conformity with accounting principles generally accepted in the United States of America (“GAAP”). Under the modified cash basis method: • Royalty income is recognized when received by Marine. • Marine’s expenses (which include accounting, legal, and other professional fees, Trustees’ fees and out-of-pocket expenses) are recorded on an actual paid basis. Reserves for liabilities that are contingent or uncertain in amount may also be established if considered necessary. • Distributions to unitholders are recognized when declared by the Trustee of the Trust. The financial statements of Marine differ from financial statements prepared in conformity with GAAP because of the following: 25 Table of Contents • Royalty income is recognized in the month received rather than in the month of production. • Reserves may be established for contingencies that would not be recorded under GAAP. • Expenses are recorded in the month paid rather than in the month incurred. • Depletion is not recorded. This comprehensive basis of accounting corresponds to the accounting principles permitted for royalty trusts by the Securities and Exchange Commission (the “SEC”), as specified by Staff Accounting Bulletin Topic 12:E, Financial Statements of Royalty Trusts. Revenue Recognition . In May 2014, the FASB issued updated guidance for recognizing revenue from contracts with customers. This update amends the existing accounting standards for revenue recognition and is based on the principle that revenue should be recognized to depict the transfer of goods and services to a customer at an amount that reflects the consideration a company expects to receive in exchange for those goods or services and revenue streams related solely to oil and gas royalties. The Trust has adopted the disclosure standards of this update, as required, beginning with the first quarter of fiscal year 2019. The adoption of this standard has not had a significant impact on its financial statements due to the modified cash basis of reporting used by the Trust. (3) Investment in Affiliate – Tidelands Royalty Trust “B” At June 30, 2021, the Trust owned 32.6% of the outstanding units of beneficial interest in Tidelands Royalty Trust “B” (“Tidelands”), which entity was wound up prior to June 30, 2022. The 452,366 units owned by the Trust had a market value of $194,517 at June 30, 2021, based on the closing price of Tideland’s units on the OTC Pink marketplace on such date. Due to Tidelands being wound up prior to June 30, 2022, there was no market underlying the 452,366 units owned by the Trust on June 30, 2022. However, expenses and fees to be reimbursed to the Trustee does exist as a payable of $154,196 as of June 30, 2022. The following summary financial statements have been derived from the unaudited consolidated financial statements of Tidelands: TIDELANDS CONSOLIDATED STATEMENTS OF ASSETS, LIABILITIES AND TRUST CORPUS June 30, 2022 June 30, 2021 Assets Current assets: Cash and cash equivalents $ 154,196 $ 469,439 Oil, natural gas and other mineral properties — 2 Total assets $ 154,196 $ 469,411 Liabilities and Trust Corpus Current liabilities: Income distributable to unitholders $ — $ — Other payable $ 154,196 $ 102,794 Federal income taxes payable $ — $ — Total current liabilities $ 154,196 $ 102,794 Trust corpus – 1,386,525 units of beneficial interest authorized, 1,386,375 issued at nominal value $ — $ 366,647 $ 154,196 $ 469,441 26 Table of Contents TIDELANDS CONSOLIDATED STATEMENTS OF DISTRIBUTABLE INCOME Twelve Months Ended June 30, 2022 2021 2020 Income $ — $ — $ 5,872 Expenses 27,826 27,042 23,265 Distributable income before Federal income taxes (27,826 ) (27,042 ) (17,393 ) Federal income taxes of Tidelands’ subsidiary — — — Distributable income $ (27,826 ) $ (27,042 ) $ (17,393 ) Tidelands was a reporting company under the Securities Exchange Act of 1934, as amended. On March 8, 2019, Tidelands terminated the registration of its units under Section 12(g) of the Exchange Act, and suspended its reporting obligations under Section 13(a) of the Exchange Act. As of that date, Tidelands’ obligations to file certain reports with the SEC, including annual, quarterly and current reports on Form 10-K, Form 10-Q and Form 8-K, respectively, were automatically and immediately suspended. The last regular distribution Marine received from Tidelands was in the fourth quarter of 2018. The term of Tidelands expired in 2021. Tidelands has been wound up and declared January 31, 2022 as the record date for the final distribution which was paid in February 2022. (4) Summary of Quarterly Financial Data (Unaudited) The following quarterly financial information for fiscal years 2022 and 2021 is unaudited; however, in the opinion of management, all adjustments necessary for a fair statement of the results of operations for the interim periods have been included.

Marine’s share of oil and natural gas sold for its royalty interests and Marine’s equity in oil and natural gas sold for Tidelands’ royalty interests were as follows: 27 Table of Contents Twelve Months Ended June 30, 2022 2021 2020 Marine: Oil (bbls) 16,096 9,085 12,628 Gas (mcf) 15,221 8,539 33,639 Tidelands: Oil (bbls) 0 0 0 Gas (mcf) 0 0 0 (6) Texas Franchise Tax Texas imposes a franchise tax that applies to most business entities that are formed or qualified to do business, or which are otherwise doing business, in Texas. Under the Texas franchise tax, a 0.75% tax is imposed for reports due in 2022 on each taxable entity’s taxable margin that is apportioned to Texas. Taxable margin is generally defined as revenues less certain costs. Taxable entities include most entities that provide owners with limited liability protection, including trusts. There are certain exemptions from the franchise tax, including exclusions for certain “passive entities” that satisfy specified statutory requirements as described below and entities with total revenues below a specified threshold. Under the Texas franchise tax, “passive entities” include trusts that meet the following requirements: (a) the trust cannot be a business trust within the meaning of U.S. Treasury Regulation section 301.7701-4(b); (b) at least 90% of the trust’s income for the taxable year must be derived from passive sources (e.g., royalties, bonuses, delay rental income from mineral properties, dividends, interest, and net gains from the sale of securities); and (c) no more than 10% of the trust’s income for the taxable year can be derived from an active trade or business (e.g., rent and certain income received by a non-operator under a joint operating agreement pursuant to which the operator is the member of an affiliated group that includes such non-operator). An entity will determine on an annual basis whether it meets the requirements to be treated as a “passive entity” for the Texas franchise tax. The Trustee believes that all or substantially all of the income of the Trust currently is passive, as it consists of royalty income from the sale of oil and natural gas, dividends and interest income. Thus, the Trust anticipates that it will be a passive entity in the tax year ending in 2022. Subject to any change in the sources of income derived by the Trust or any change in the Indenture, the Trust expects that it will continue to qualify as a passive entity that is not subject to the Texas franchise tax. If the Trust is exempt from the Texas franchise tax as a passive entity, each unitholder that is subject to the Texas franchise tax as a taxable entity under the Texas Tax Code should generally include its share of the Trust’s revenue in its franchise tax computation. The Texas franchise tax does not apply to natural persons. In the event the Trust does not qualify as a passive entity, it would not be required to pay any tax and is not considered to owe any Texas franchise tax for any period in which its annualized total revenue is less than or equal to a certain threshold. For reports due on or after January 1, 2022 and before January 1, 2024, this no tax due threshold is $1,230,000. Each unitholder is urged to consult its own tax advisor regarding the requirements for filing state tax returns. 28 Table of Contents SIGNATURES Pursuant to the requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned, thereunto duly authorized.
