TABLE OF CONTENTS

GLOSSARY OF CERTAIN OIL AND NATURAL GAS TERMS

In this Form 10-K the following terms have the meanings specified below.

Bbl — One stock tank barrel, or 42 U.S. gallons liquid volume, of crude oil or other liquid hydrocarbons.

Boe — One stock tank barrel of oil equivalent, computed on an approximate energy equivalent basis that one Bbl of crude oil equals six Mcf of natural gas and one Bbl of crude oil equals 1.54 Bbls of natural gas liquids.

Btu or British Thermal Unit — The quantity of heat required to raise the temperature of one pound of water one degree Fahrenheit.

Developed Acreage — The number of acres that are allocated or assignable to productive wells or wells capable of production.

Development Well — A well drilled within the proved area of an oil or natural gas reservoir to the depth of a stratigraphic horizon known to be productive.

DUCs — Drilled but uncompleted. A well that has been drilled but has not undergone the final steps of perforating/acidizing or hydraulic fracturing and procedures necessary to place the well on production.

Estimated Future Net Revenues — Also referred to as “estimated future net cash flows.” The result of applying current prices of oil, natural gas and natural gas liquids to estimated future production from oil, natural gas and natural gas liquids proved reserves, reduced by estimated future expenditures, based on current costs to be incurred, in developing and producing the proved reserves.

Field — An area consisting of a single reservoir or multiple reservoirs all grouped on or related to the same individual geological structural feature and/or stratigraphic condition. There may be two or more reservoirs in a field that are separated vertically by intervening impervious, strata, or laterally by local geologic barriers, or by both. Reservoirs that are associated by being in overlapping or adjacent fields may be treated as a single or common operational field. The geological terms structural feature and stratigraphic condition are intended to identify localized geological features as opposed to the broader terms of basins, trends, provinces, plays, areas-of-interest, etc.

Gross Acres or Gross Wells — The total acres or wells, as the case may be, in which a working interest is owned.

Henry Hub — A distribution hub on the natural gas pipeline system in Erath, Louisiana. It is the pricing point for natural gas futures contracts traded on the New York Mercantile Exchange and the over the counter swaps traded on Intercontinental Exchange. Spot and future natural gas prices set at Henry Hub are denominated in USD per MMBtu.

Mba — One thousand barrels of crude oil or other liquid hydrocarbons.

MBoe — One thousand barrels of oil equivalent.

Mcf — One thousand standard cubic feet of natural gas.

MMBbls — One million barrels of crude oil or other liquid hydrocarbons.

MMBoe — One million barrels of oil equivalent.

MMBtu — One million British Thermal Units.

MMcf — One million standard cubic feet of natural gas.

Net Acres or Net Wells — The sum of the fractional working interests owned in gross acres or wells, respectively.

Net Profits Interest — A nonoperating interest that creates a share in gross production from an operating or working interest in oil and natural gas properties. The share is measured by net profits from the sale of production after deducting costs associated with that production.

TABLE OF CONTENTS

Net Revenue Interest — An interest in all oil, natural gas and natural gas liquids produced and saved from, or attributable to, a particular property, net of all royalties, overriding royalties, net profits interests, carried interests, reversionary interests and any other burdens to which the person’s interest is subject.

NGLs — Natural gas liquids.

NYMEX — New York Mercantile Exchange.

Plugging and Abandonment — Activities to remove production equipment and seal off a well at the end of a well’s economic life.

Proved Developed Non-Producing Reserves — Proved developed reserves expected to be recovered from zones behind casing in existing wells.

Proved Developed Oil and Gas Reserves — Proved Oil and Gas Reserves that can be expected to be recovered:

(A)

through existing wells with existing equipment and operating methods or in which the cost of the required equipment is relatively minor compared to the cost of a new well; and

(B)

through installed extraction equipment and infrastructure operational at the time of the reserves estimate if the extraction is by means not involving a well.

Proved Developed Producing Reserves — Proved developed reserves that are expected to be recovered from completion intervals currently open in existing wells and capable of production to market.

Proved Oil and Gas Reserves — Those quantities of oil and gas that, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible — from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulations — prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. The project to extract the hydrocarbons must have commenced or the operator must be reasonably certain that it will commence the project within a reasonable time.

(A)

The area of a reservoir considered as proved includes: (i) the area identified by drilling and limited by fluid contacts, if any, and (ii) adjacent undrilled portions of the reservoir that can, with reasonable certainty, be judged to be continuous with it and to contain economically producible oil or gas on the basis of available geoscience and engineering data.

(B)

In the absence of data on fluid contacts, proved quantities in the reservoir are limited by the lowest known hydrocarbons, as seen in a well penetration unless geoscience, engineering, or performance data and reliable technology establishes a lower contact with reasonable certainty.

(C)

Where direct observation from well penetrations has defined a highest known oil elevation and the potential exists for an associated gas cap, proved oil reserves may be assigned in the structurally higher portions of the reservoir only if geoscience, engineering, or performance data and reliable technology establish the higher contact with reasonable certainty.

(D)

Reserves that can be produced economically through application of improved recovery techniques (including, but not limited to, fluid injection) are included in the proved classification when (i) successful testing by a pilot project in an area of the reservoir with properties no more favorable than in the reservoir as a whole, the operation of an installed program in the reservoir or an analogous reservoir, or other evidence using reliable technology establishes the reasonable certainty of the engineering analysis on which the project or program was based and (ii) the project has been approved for development by all necessary parties and entities, including governmental entities.

(E)

Existing economic conditions include prices and costs at which economic producibility from a reservoir is determined. The price is the average price during the 12-month period prior to the ending date of the period covered by the report, determined as an unweighted arithmetic average of the first-day-of-the-month price for each month within such period, unless prices are defined by contractual arrangements, excluding escalations based upon future conditions.

TABLE OF CONTENTS

Proved Undeveloped Oil and Gas Reserves — Proved Oil and Gas Reserves that are expected to be recovered from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is required for recompletion.

(A)

Reserves on undrilled acreage are limited to those directly offsetting development spacing areas that are reasonably certain of production when drilled, unless evidence using reliable technology exists that establishes reasonable certainty of economic producibility at greater distances.

(B)

Undrilled locations can be classified as having undeveloped reserves only if a development plan has been adopted indicating that they are scheduled to be drilled within five years, unless the specific circumstances justify a longer time.

(C)

Under no circumstances are estimates for undeveloped reserves to be attributable to any acreage for which an application of fluid injection or other improved recovery technique is contemplated, unless such techniques have been proved effective by actual projects in the same reservoir or an analogous reservoir or by other evidence using reliable technology establishing reasonable certainty.

Recompletion — The process of re-entering an existing wellbore that is either producing or not producing and completing new reservoirs in an attempt to establish or increase existing production.

Reservoir — A porous and permeable underground formation containing a natural accumulation of producible oil and/or natural gas that is confined by impermeable rock or water barriers and is individual and separate from other reservoirs.

Standardized Measure of Discounted Future Net Cash Flows — Also referred to herein as “standardized measure.” It is the present value of estimated future net revenues computed by discounting estimated future net revenues at a rate of 10% annually.

The Financial Accounting Standards Board requires disclosure of standardized measure of discounted future net cash flows relating to proved oil and gas reserve quantities per accounting literature for extractive activities — oil and gas, as follows: A standardized measure of discounted future net cash flows relating to an enterprise’s interests in (a) proved oil and gas reserves and (b) oil and gas subject to purchase under long-term supply, purchase, or similar agreements and contracts in which the enterprise participates in the operation of the properties on which the oil or gas is located or otherwise serves as the producer of those reserves shall be disclosed as of the end of the year. The standardized measure of discounted future net cash flows relating to those two types of interests in reserves may be combined for reporting purposes. The following information shall be disclosed in the aggregate and for each geographic area for which reserve quantities are disclosed:

Future cash inflows. These shall be computed by the average of the first-day-of-the-month prices during the 12-month period preceding the end of the year for 2023, 2024 and 2025 of oil and gas relating to the enterprise’s proved reserves to the year-end quantities of those reserves. Future price changes shall be considered only to the extent provided by contractual arrangements in existence at year-end.

Future development and production costs. These costs shall be computed by estimating the expenditures to be incurred in developing and producing the proved oil and gas reserves at the end of the year, based on year-end costs and assuming continuation of existing economic conditions. If estimated development expenditures are significant, they shall be presented separately from estimated production costs.

Future income tax expenses. These expenses shall be computed by applying the appropriate year-end statutory tax rates, with consideration of future tax rates already legislated, to the future pretax net cash flows relating to the enterprise’s proved oil and gas reserves, less the tax basis of the properties involved. The future income tax expenses shall give effect to tax deductions, tax credits and allowances relating to the enterprise’s proved oil and gas reserves.

Future net cash flows. These amounts are the result of subtracting future development and production costs and future income tax expenses from future cash inflows.

TABLE OF CONTENTS

Discount. This amount shall be derived from using a discount rate of 10 percent a year to reflect the timing of the future net cash flows relating to proved oil and gas reserves.

Standardized measure of discounted future net cash flows. This amount is the future net cash flows less the computed discount.

Working Interest — Also called an operating interest. The right granted to the lessee of a property to explore for and to produce and own oil, gas or other minerals. The working interest owner bears the exploration, development and operating costs on either a cash, penalty or carried basis.

Workover — Operations on a producing well to restore or increase production.

WTI Cushing — West Texas Intermediate, a type of crude oil used as a benchmark in oil pricing and the underlying commodity of NYMEX oil futures contracts for delivery at Cushing, Oklahoma.

TABLE OF CONTENTS

PART I

Item 1. Business.

General

MV Oil Trust (the “Trust”) was formed in August 2006 by MV Partners, LLC (“MV Partners”). Much of the information disclosed in this Form 10-K has been provided to the Trust by MV Partners, including information associated with the underlying properties (as defined below) such as production and well counts, major producing areas, customer relationships, competition, marketing and post-production services, and certain information on which reserve data is based.

The Trust is a statutory trust created under the Delaware Statutory Trust Act pursuant to a Trust Agreement (as subsequently amended and restated, the “Trust Agreement”) among MV Partners, as trustor, The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”), and Wilmington Trust Company, as Delaware trustee (the “Delaware Trustee”). The Trust does not have any employees, and the business and affairs of the Trust are managed by the Trustee. The Trust maintains its offices at the office of the Trustee, at 601 Travis Street, Floor 16, Houston, Texas 77002. The telephone number of the Trustee is 1-855-802-1094. The Delaware Trustee has only minimal rights and duties as are necessary to satisfy the requirements of the Delaware Statutory Trust Act.

The Trust maintains a website at http://mvo.q4web.com/home/default.aspx. The Trust’s filings under the Exchange Act are available through its website and are also available electronically from the website maintained by the Securities and Exchange Commission (the “SEC”) at www.sec.gov.

On January 24, 2007, MV Partners and the Trust completed an initial public offering of units of beneficial interest in the Trust (the “Trust Units”). In connection with the completion of the initial public offering of Trust Units, on January 24, 2007, MV Partners conveyed a term net profits interest to the Trust that represents the right to receive 80% of the net proceeds (calculated as described below) from all of MV Partners’ interests in oil and natural gas properties as of January 24, 2007 (the “net profits interest”), pursuant to the Conveyance of net profits interest dated as of January 24, 2007 (the “Conveyance”). These properties are located in the Mid-Continent region in the States of Kansas and Colorado. MV Partners’ net interests in such properties, after deduction of all royalties and other burdens on production thereon as of January 24, 2007, are referred to in this Form 10-K as the “underlying properties.” As of December 31, 2025, the underlying properties produced predominantly oil from approximately 830 wells, and the projected reserve life of the underlying properties was over 28 years. Based on the summary prepared by Cawley, Gillespie & Associates, Inc., independent petroleum and geological engineers (“CG&A”), of its reserve report as of December 31, 2025 for the Trust, which is summarized herein under “— Description of the Underlying Properties — Reserves” and is referred to herein as the “reserve report,” the net profits interest would entitle the Trust to receive net proceeds from the sale of production of not less than 11.5 MMBoe of proved reserves during the term of the Trust, calculated as 80% of the proved reserves attributable to the underlying properties expected to be produced during the term of the Trust. Of these reserves, 100% were classified as proved developed producing reserves as of December 31, 2025. Production volumes from the underlying properties for the year ended December 31, 2025 were approximately 99% oil and approximately 1% natural gas and natural gas liquids. The underlying properties are all located in mature fields that are characterized by long production histories and numerous additional development opportunities to help reduce the natural decline in production from the underlying properties.

As of December 31, 2025, cumulatively, since inception, the Trust has received payment for 80% of the net proceeds attributable to MV Partners’ interest from the sale of 15.3 MMBoe of production from the underlying properties (which amount is the equivalent of 12.2 MMBoe with respect to the Trust’s net profits interest). Consequently, pursuant to the terms of the Conveyance, the net profits interest will terminate on June 30, 2026 (the “Termination Date”), because the minimum amount of production (14.4 MMBoe) applicable to the net profits interest has been produced and sold (which amount is the equivalent of 11.5 MMBoe with respect to the Trust’s net profits interest). The Trustee will make a final quarterly cash distribution, if any, on or about July 24, 2026 to the Trust unitholders of record on the 15th day following June 30, 2026, and the Trust Units are expected to be cancelled shortly thereafter. The Trust will not be entitled to any net proceeds that MV Partners receives after the Termination Date from the sale of production from

TABLE OF CONTENTS

the underlying properties. The Trust will dissolve and commence winding up its business and affairs after the Termination Date, and once the Trust winds up and terminates, it will pay no further distributions.

The gross proceeds used to calculate the net proceeds payable to the Trust are based on prices realized for oil, natural gas and natural gas liquids attributable to the underlying properties for each calendar quarter during the term of the net profits interest. In calculating the net proceeds, MV Partners deducts from the gross proceeds from the underlying properties all lease operating expenses, maintenance expenses and capital expenditures (including the cost of workovers and recompletions, drilling costs and development costs), amounts that may be reserved for future expenditures (which reserve amounts may not exceed $1.0 million in the aggregate at any given time), post-production costs and production and property taxes paid by MV Partners.

Net proceeds payable to the Trust depend upon production quantities, sales prices of oil, natural gas and natural gas liquids, and costs to develop and produce the oil, natural gas and natural gas liquids. If at any time costs should exceed gross proceeds, neither the Trust nor the Trust unitholders would be liable for the excess costs; the Trust, however, would not receive any net proceeds until future net proceeds exceed the total amount of those excess costs, plus interest at the prime rate.

The Trust will make quarterly cash distributions of substantially all of its quarterly cash receipts, after deduction of fees and expenses for the administration of the Trust and any cash the Trustee decides to hold as a reserve against future expenses, to holders of its Trust Units during the term of the Trust. Because payments to the Trust will be generated by depleting assets and the Trust has a finite life with the production from the underlying properties diminishing over time, a portion of each distribution will represent a return of the original investment in the Trust Units.

The Trust was created to acquire and hold the net profits interest for the benefit of the Trust unitholders. The net profits interest is passive in nature and neither the Trust nor the Trustee has any control over or responsibility for costs relating to the operation of the underlying properties. The business and affairs of the Trust are managed by the Trustee, and MV Partners and its affiliates have no ability to manage or influence the operations of the Trust. The underlying properties, for which MV Partners is designated as the operator, are currently operated on a contract operator basis by Vess Oil Corporation (“Vess Oil”) and Murfin Drilling Company, Inc. (“Murfin Drilling”), each of which is an affiliate of MV Energy, LLC (“MV Energy”), the sole manager of MV Partners. MV Partners does not, as a matter of course, make public projections as to future sales, earnings or other results relating to the underlying properties.

Description of the Trust Units

Each Trust Unit is a unit of beneficial interest in the Trust and is entitled to receive cash distributions from the Trust on a pro rata basis. Each Trust unitholder has the same rights regarding each of his or her Trust Units as every other Trust unitholder has regarding his or her Trust Units. The Trust Units are in book-entry form only and are not represented by certificates. The Trust had 11,500,000 Trust Units outstanding as of March 24, 2026.

Distributions and Income Computations

Each quarter, the Trustee determines the amount of funds available for distribution to the Trust unitholders. Available funds are the excess cash, if any, received by the Trust from the net profits interest and other sources (such as interest earned on any amounts reserved by the Trustee) in that quarter, over the Trust’s expenses for that quarter. Available funds are reduced by any cash the Trustee decides to hold as a reserve against future expenses. Quarterly cash distributions during the term of the Trust are made by the Trustee on or before the 25th day of the month following the end of each quarter to the Trust unitholders of record on the 15th day of the month following the end of each quarter (or the next succeeding business day).

Unless otherwise advised by counsel or the Internal Revenue Service (the “IRS”), the Trustee will treat the income and expenses of the Trust for each quarter as belonging to the Trust unitholders of record on the quarterly record date. For federal income tax purposes, Trust unitholders must take into account items of income, gain, loss, deduction and credit consistent with their methods of accounting and without regard to

TABLE OF CONTENTS

the taxable year or accounting method employed by the Trust and without regard to the quarter in which the Trust makes distributions related to those items to the Trust unitholders. Variances between taxable income and cash distributions may occur. For example, the Trustee could establish a reserve in one quarter using funds that would be included in income in the quarter in which the reserve is created but may not result in a tax deduction or a distribution until a later quarter or possibly in a later taxable year. Similarly, the Trustee could also make a payment in one quarter that would be amortized for income tax purposes over several quarters. See “— Federal Income Tax Matters.”

Periodic Reports

The Trustee files all required Trust federal and state income tax and information returns. The Trustee prepares and provides the tax information that Trust unitholders need to correctly report their share of the income and deductions of the Trust. The Trustee also causes to be prepared and filed reports required to be filed under the Exchange Act and by the rules of any securities exchange or quotation system on which the Trust Units are listed or admitted to trading, and also causes the Trust to comply with the provisions of the Sarbanes-Oxley Act of 2002, including but not limited to, by establishing, evaluating and maintaining a system of internal control over financial reporting in compliance with the requirements of Section 404 thereof.

Each Trust unitholder and his or her representatives may examine, for any proper purpose, during reasonable business hours, the records of the Trust and the Trustee.

Liability of Trust Unitholders

Under the Delaware Statutory Trust Act, Trust unitholders are entitled to the same limitation of personal liability extended to stockholders of private corporations for profit under the General Corporation Law of the State of Delaware. Courts in jurisdictions outside of Delaware, however, may not give effect to such limitation.

Voting Rights of Trust Unitholders

The Trustee or Trust unitholders owning at least 10% of the outstanding Trust Units may call meetings of Trust unitholders. The Trust is responsible for all costs associated with calling a meeting of Trust unitholders unless such meeting is called by Trust unitholders, in which case the Trust unitholders calling the meeting are responsible for all such costs. Meetings must be held in such location as is the Trustee designates in the notice of such meeting. The Trustee must send written notice of the time and place of the meeting and the matters to be acted upon to all of the Trust unitholders at least 20 days and not more than 60 days before the meeting. Trust unitholders representing a majority of Trust Units outstanding must be present or represented to have a quorum. Each Trust unitholder is entitled to one vote for each Trust Unit owned.

Unless otherwise required by the Trust Agreement, a matter may be approved or disapproved by the vote of a majority of the Trust Units held by the Trust unitholders at a meeting where there is a quorum. This is true even if a majority of the total Trust Units did not approve it. The affirmative vote of the holders of a majority of the outstanding Trust Units is required to:

•

dissolve the Trust;

•

remove the Trustee or the Delaware Trustee;

•

amend the Trust Agreement (except with respect to certain matters that do not adversely affect the rights of Trust unitholders in any material respect);

•

merge or consolidate the Trust with or into another entity; or

•

approve the sale of all or any material part of the assets of the Trust.

In addition, the Trustee may make certain amendments to the Trust Agreement without approval of the Trust unitholders. The Trustee must consent before all or any part of the Trust assets can be sold except in connection with the dissolution of the Trust or limited sales directed by MV Partners in conjunction with its sale of underlying properties.

TABLE OF CONTENTS

Duration of the Trust; Sale of the Net Profits Interest

The Trust will remain in existence until shortly after the Termination Date, which is June 30, 2026, since 14.4 MMBoe have been produced from the underlying properties and sold (which amount is the equivalent of 11.5 MMBoe in respect of the Trust’s right to receive 80% of the net proceeds from the underlying properties pursuant to the net profits interest). The net profits interest will terminate on the Termination Date, at which point the Trust will dissolve and commence winding up its business and affairs. It is anticipated that the Trustee will make a final quarterly cash distribution, if any, shortly after the Termination Date to the Trust unitholders of record on the 15th day following June 30, 2026, and the Trust Units are expected to be cancelled shortly thereafter.

The Trust will dissolve and commence winding up its business and affairs prior to the Termination Date if:

•

the Trust sells the net profits interest;

•

the holders of a majority of the outstanding Trust Units vote in favor of dissolution; or

•

there is a judicial dissolution of the Trust.

Upon dissolution, the Trustee would then sell all of the Trust’s assets, which are limited to the net profits interest, and do not include the underlying properties, either by private sale or public auction, and distribute the net proceeds of the sale to the Trust unitholders. As the net profits interest will terminate as of the Termination Date, there will be no sale of the net profits interest following June 30, 2026.

Computation of Net Proceeds

The provisions of the Conveyance governing the computation of the net proceeds are detailed and extensive. The following information summarizes the material information contained in the Conveyance related to the computation of the net proceeds. For more detailed provisions concerning the net profits interest, please see the Conveyance, which is included as an exhibit to this Form 10-K.

Net Profits Interest

The term net profits interest was conveyed to the Trust by MV Partners on January 24, 2007 by means of a conveyance instrument that has been recorded in the appropriate real property records in each county in Kansas and Colorado where the oil and natural gas properties to which the underlying properties relate are located. The net profits interest burdens the net interests owned by MV Partners in the underlying properties in existence as of January 24, 2007.

The amounts paid to the Trust for the net profits interest are based on the definitions of “gross proceeds” and “net proceeds” contained in the Conveyance and described below. Under the Conveyance, net proceeds are computed quarterly, and 80% of the aggregate net proceeds attributable to a computation period will be paid to the Trust on or before the 25th day of the month following the computation period. MV Partners will not pay to the Trust any interest on the net proceeds held by MV Partners prior to payment to the Trust. The Trustee will make distributions to Trust unitholders quarterly, if sufficient funds are available. See “— Description of the Trust Units — Distributions and Income Computations.”

“Gross proceeds” mean the aggregate amount received by MV Partners from sales of oil, natural gas and natural gas liquids produced from the underlying properties (other than amounts received for certain future non-consent operations).

Gross proceeds does not include consideration for the transfer or sale of any underlying property by MV Partners or any subsequent owner to any new owner unless the net profits interest is released (as is permitted in certain circumstances). Gross proceeds also does not include any amount for oil, natural gas or natural gas liquids lost in production or marketing or used by the owner of the underlying properties in drilling, production and plant operations. Gross proceeds includes payments for future production if they are not subject to repayment in the event of insufficient subsequent production.

TABLE OF CONTENTS

“Net proceeds” means gross proceeds less the following:

•

all payments to mineral owners or landowners, such as royalties or other burdens against production, delay rentals, shut-in oil and natural gas payments, minimum royalty or other payments for drilling or deferring drilling;

•

any taxes paid by the owner of an underlying property to the extent not deducted in calculating gross proceeds, including estimated and accrued general property (ad valorem), production, severance, sales, gathering, excise and other taxes;

•

any extraordinary taxes or windfall profits taxes that may be assessed in the future that are based on profits realized or prices received for production from the underlying properties;

•

costs paid by an owner of a property comprising the underlying properties under any joint operating agreement;

•

all other costs and expenses, capital costs and liabilities of exploring for, drilling, recompleting, workovers, operating and producing oil, natural gas and natural gas liquids, including allocated expenses such as labor, vehicle and travel costs and materials and any plugging and abandonment liabilities (net of any capital costs for which a reserve had already been made to the extent such capital costs are incurred during the computation period) other than costs and expenses for certain future non-consent operations;

•

costs or charges associated with gathering, treating and processing oil, natural gas and natural gas liquids;

•

any overhead charge incurred pursuant to any operating agreement relating to an underlying property, including the overhead fee payable by MV Partners to Vess Oil and Murfin Drilling as described below;

•

amounts previously included in gross proceeds but subsequently paid as a refund, interest or penalty;

•

costs and expenses for renewals or extensions of leases; and

•

at the option of MV Partners (or any subsequent owner of the underlying properties), amounts reserved for approved exploration, development, maintenance or operating expenditures, including well drilling, recompletion and workover costs, which amounts will at no time exceed $1.0 million in the aggregate, and will be subject to the limitations described below.

During each twelve-month period beginning on June 30, 2023 (the “Capital Expenditure Limitation Date”), the sum of the capital expenditures and amounts reserved for approved capital expenditure projects for such twelve-month period may not exceed the Average Annual Capital Expenditure Amount. The “Average Annual Capital Expenditure Amount” means the quotient of (x) the sum of the capital expenditures and amounts reserved for approved capital expenditure projects with respect to the three twelve-month periods ending on the Capital Expenditure Limitation Date, divided by (y) three. Commencing on the Capital Expenditure Limitation Date, and each anniversary of the Capital Expenditure Limitation Date thereafter, the Average Annual Capital Expenditure Amount will be increased by 2.5% to account for expected increased costs due to inflation. The Average Annual Capital Expenditure Amount for the twelve-month period ending June 30, 2026 is $2,336,477.

As is customary in the oil and natural gas industry, MV Partners pays an overhead fee to Vess Oil and Murfin Drilling to operate the underlying properties on behalf of MV Partners. The operating activities include various engineering, accounting and administrative functions. The fee is based on a monthly charge per active operated well, which totaled $3.4 million in 2023, $3.6 million in 2024 and $3.8 million in 2025 for all of the underlying properties for which MV Partners was designated as the operator. The fee is adjusted annually and will increase or decrease each year based on changes in the year-end index of average weekly earnings of crude petroleum and natural gas workers.

If the net proceeds for any computation period is a negative amount, the Trust will receive no payment for that period, and any such negative amount plus accrued interest at the prime rate will be deducted from gross proceeds in the following computation period for purposes of determining the net proceeds for that following computation period. Gross proceeds and net proceeds are calculated on a cash receipts and cash disbursements basis.

TABLE OF CONTENTS

Additional Provisions

If a controversy arises as to the sales price of any production, then for purposes of determining gross proceeds:

•

amounts withheld or placed in escrow by a purchaser are not considered to be received by the owner of the underlying property until actually collected;

•

amounts received by the owner of the underlying property and promptly deposited with a nonaffiliated escrow agent will not be considered to have been received until disbursed to it by the escrow agent; and

•

amounts received by the owner of the underlying property and not deposited with an escrow agent will be considered to have been received.

The Trustee is not obligated to return any cash received from the net profits interest. Any overpayments that MV Partners makes to the Trust due to adjustments to prior calculations of net proceeds or otherwise will reduce future amounts payable to the Trust until MV Partners recovers the overpayments plus interest at the prime rate.

The Conveyance generally permits MV Partners to transfer without the consent or approval of the Trust unitholders all or any part of its interest in the underlying properties, subject to the net profits interest. The Trust unitholders are not entitled to any proceeds of a sale or transfer of MV Partners’ interest unless the Trust is required to sell the net profits interest as to such interest. Following a sale or transfer, the underlying properties will continue to be subject to the net profits interest, and the net proceeds attributable to the transferred property will be calculated as part of the computation of net proceeds described in this Form 10-K.

In addition, MV Partners may, without the consent of the Trust unitholders, require the Trust to release the net profits interest associated with any lease that accounts for less no more than 0.25% of the total production from the underlying properties in the prior 12 months and provided that the net profits interest covered by such releases cannot exceed, during any 12-month period, an aggregate fair market value to the Trust of $500,000. These releases will be made only in connection with a sale by MV Partners to a non-affiliate of the relevant underlying properties and are conditioned upon the Trust receiving an amount equal to the fair market value to the Trust of such net profits interest. Any net sales proceeds paid to the Trust are distributable to Trust unitholders for the quarter in which they are received.

As the designated operator of the properties comprising the underlying properties, MV Partners may enter into farm-out, operating, participation and other similar agreements to develop the property. MV Partners may enter into any of these agreements without the consent or approval of the Trustee or any Trust unitholder.

MV Partners and any transferee of an underlying property will have the right to abandon its interest in any well or property if it reasonably believes the well or property ceases to produce or is not capable of producing in commercially paying quantities. In making such decisions, MV Partners or any transferee of an underlying property is required under the applicable conveyance to act as a reasonably prudent operator in the State of Kansas under the same or similar circumstances would act if it were acting with respect to its own properties, disregarding the existence of the net profits interest as a burden on such property. Upon termination of the lease, the portion of the net profits interest relating to the abandoned property will be extinguished.

MV Partners must maintain books and records sufficient to determine the amounts payable for the net profits interest to the Trust. Quarterly and annually, MV Partners must deliver to the Trustee a statement of the computation of the net proceeds for each computation period. The Trustee has the right to inspect and copy the books and records maintained by MV Partners during normal business hours and upon reasonable notice.

Federal Income Tax Matters

The following is a summary of certain federal income tax matters that may be relevant to Trust unitholders. This summary is based upon current provisions of the Internal Revenue Code of 1986, as

TABLE OF CONTENTS

amended (the “Code”), existing and proposed Treasury regulations thereunder and current administrative rulings and court decisions, all of which are subject to changes or different interpretation at any time, possibly with retroactive effect. No attempt has been made in the following summary to comment on all federal income tax matters affecting the Trust or the Trust unitholders.

The summary is limited to Trust unitholders who are individual citizens or residents of the United States. Accordingly, the following summary has limited application to domestic corporations and persons subject to specialized federal income tax treatment. Each Trust unitholder should consult his or her own tax advisor with respect to his or her particular circumstances.

Classification and Taxation of the Trust

Tax counsel to the Trust advised the Trust at the time of formation that, for federal income tax purposes, in its opinion the Trust will be treated as a grantor trust and not as an unincorporated business entity. No ruling has been or will be requested from the IRS with respect to the federal income tax treatment of the Trust, including as to the status of the Trust as a grantor trust for such purposes. Thus, no assurance can be provided that the tax treatment of the Trust would be sustained by a court if contested by the IRS or another taxing authority. The remainder of the discussion below is based on tax counsel’s opinion, at the time of formation, that the Trust will be classified as a grantor trust for federal income tax purposes. As a grantor trust, the Trust will not be subject to federal income tax at the Trust level. Rather, each Trust unitholder will be considered for federal income tax purposes to own its proportionate share of the Trust’s assets directly as though no trust were in existence. The income of the Trust is deemed to be received or accrued by the Trust unitholder at the time such income is received or accrued by the Trust, rather than when distributed by the Trust. Each Trust unitholder will be subject to tax on its proportionate share of the income and gain attributable to the assets of the Trust and will be entitled to claim its proportionate share of the deductions and expenses attributable to the assets of the Trust, subject to applicable limitations, in accordance with the Trust unitholder’s taxable year and tax method of accounting and without regard to the taxable year or accounting method employed by the Trust.

The Trust will allocate items of income, gain, loss, deductions and credits to Trust unitholders based on record ownership at each quarterly record date. It is possible that the IRS or another taxing authority could disagree with this allocation method and could assert that income and deductions of the Trust should be determined and allocated on a daily, prorated or other basis, which could require adjustments to the tax returns of the Trust unitholders affected by this issue and result in an increase in the administrative expense of the Trust in subsequent periods.

Classification of the Net Profits Interest

Tax counsel to the Trust also advised the Trust at the time of formation that, for federal income tax purposes, based upon representations made by MV Partners regarding the expected economic life of the underlying properties and the expected duration of the net profits interest, in its opinion the net profits interest should be treated as a “production payment” under Section 636 of the Code or otherwise as a debt instrument. On the basis of that advice, the Trust will treat the net profits interest as indebtedness subject to Treasury regulations applicable to contingent payment debt instruments, and by purchasing Trust Units, a Trust unitholder agrees to be bound by the Trust’s application of those regulations, including the Trust’s determination of the rate at which interest is deemed to accrue on the net profits interest. No assurance can be given that the IRS or another taxing authority will not assert that the net profits interest should be treated differently. Any such different treatment could affect the amount, timing and character of income, gain or loss in respect of an investment in Trust Units and could require a Trust unitholder to accrue income at a rate different than that determined by the Trust.

Widely Held Fixed Investment Trust Reporting Information

The Trustee assumes that some Trust Units are held by middlemen, as such term is broadly defined in Treasury regulations (and includes custodians, nominees, certain joint owners, and brokers holding an interest for a custodian in street name). Therefore, the Trustee considers the Trust to be a non-mortgage widely held fixed investment trust (“WHFIT”) for U.S. federal income tax purposes. The Bank of New York Mellon Trust Company, N.A., 601 Travis Street, Floor 16, Houston, Texas 77002, telephone number 1-855-802-1094,

TABLE OF CONTENTS

is the representative of the Trust that will provide tax information in accordance with applicable Treasury regulations governing the information reporting requirements of the Trust as a WHFIT. Notwithstanding the foregoing, the middlemen holding Trust Units on behalf of Trust unitholders, and not the Trustee of the Trust, are solely responsible for complying with the information reporting requirements under the Treasury regulations with respect to such Trust Units, including the issuance of IRS Forms 1099 and certain written tax statements. Trust unitholders whose Trust Units are held by middlemen should consult with such middlemen regarding the information that will be reported to them by the middlemen with respect to the Trust Units. Any generic tax information provided by the Trustee of the Trust is intended to be used only to assist Trust unitholders in the preparation of their federal and state income tax returns.

Available Trust Tax Information

In compliance with the reporting requirements for WHFITs and the dissemination of Trust tax reporting information, the Trustee provides a generic tax information reporting booklet that is intended to be used only to assist Trust unitholders in the preparation of their 2025 federal and state income tax returns. The projected payment schedule for the net profits interest is included with the tax information booklet. This tax information booklet, when available, can be obtained at http://mvo.q4web.com/home/default.aspx.

Description of the Underlying Properties

The underlying properties consist of MV Partners’ net interests in all of its oil and natural gas properties as of January 24, 2007, which properties are located in the Mid-Continent region in the States of Kansas and Colorado. Affiliates of MV Partners are the contract operators of substantially all of the underlying properties.

MV Partners’ interests in the underlying properties require MV Partners to bear its proportionate share, along with the other working interest owners, of the costs of development and operation of such properties. The underlying properties are burdened by non-working interests owned by third parties, consisting primarily of royalty interests retained by the owners of the land subject to the working interests. These landowners’ royalty interests typically entitle the landowner to receive 12.5% of the revenue derived from oil and natural gas production resulting from wells drilled on their land, without any deduction for drilling costs or other costs related to production of oil and natural gas. A working interest percentage represents a working interest owner’s proportionate ownership interest in a property in relation to all other working interest owners in that property, whereas a net revenue interest percentage is a working interest owner’s percentage of production after reducing such percentage by the percentage of burdens on such production such as royalties and overriding royalties.

Based on the reserve report, the net profits interest would entitle the Trust to receive net proceeds from the sale of production of not less than 11.5 MMBoe of proved reserves attributable to the underlying properties expected to be produced during the term of the net profits interest, calculated as 80% of the proved reserves attributable to the underlying properties expected to be produced during the term of the net profits interest. The reserves attributable to the underlying properties include all reserves expected to be economically produced during the life of the properties, whereas the Trust is entitled to only receive 80% of the net proceeds from the sale of production of oil, natural gas and natural gas liquids attributable to the underlying properties during the term of the net profits interest.

The Mid-Continent region is a mature producing region with well-known geologic characteristics. Most of the production from the underlying properties consists of desirable crude oil of a quality level between sweet and sour with 33 to 34 gravity averages. Most of the producing wells to which the underlying properties relate are relatively shallow, ranging from 600 to 4,500 feet, and many are completed to multiple producing zones. In general, the producing wells to which the underlying properties relate have stable production profiles and their production is generally long-lived, often with total projected economic lives over 50 years.

Reserves

The engineering departments of each of Vess Oil and Murfin Drilling, which together manage MV Partners and operate the underlying properties on behalf of MV Partners, maintain oversight and

TABLE OF CONTENTS

compliance responsibility for the internal reserve estimate process and, in accordance with internal policies and procedures, provide appropriate data to independent third party engineers for the annual estimation of year-end reserves. These engineering departments accumulate historical production data for the underlying properties, calculate historical lease operating expenses and differentials, update working interests and net revenue interests, and obtain logs, 3-D seismic and other geological and geophysical information. This data is forwarded to CG&A, thereby allowing CG&A to prepare estimated proved reserves in their entirety based on such data.

Estimates of the proved oil and gas reserves attributable to the Trust as of December 31, 2023, 2024 and 2025 are based on reports prepared by CG&A. CG&A has been in business since 1961 and serves many organizations and individuals in the petroleum industry, including owners and operators of oil and gas properties, exploration groups, planners, and professionals in investment and finance. One of the principal businesses of CG&A is providing detailed assessment of producing reservoirs. CG&A is an independent firm of petroleum engineers, geologists, geophysicists and petrophysicists and does not own an interest in the underlying properties and is not employed on a contingent basis. Mr. W. Todd Brooker, President, is the technical person at CG&A who is primarily responsible for overseeing CG&A’s preparation of the reserve estimates. Mr. Brooker is a graduate of the University of Texas at Austin with a Bachelor of Science degree in Petroleum Engineering and has 34 years of experience in petroleum engineering. He is a licensed professional engineer in the State of Texas (License #83462).

Oil and gas proved reserves are disclosed by significant geographic area, using the 12-month average beginning-of-month price for the year, based on the use of reliable technologies to estimate proved oil and gas reserves, if those technologies have been demonstrated to result in reliable conclusions about reserves volumes. Reserve and related information for 2023, 2024 and 2025 is presented consistent with these requirements.

Proved Reserves of MV Oil Trust. The following table sets forth, as of December 31, 2025, estimated proved reserves attributable to the Trust derived from the reserve report. A summary of the reserve report is included below.

The reserves above represent the Trust’s 80% net profits interest in the underlying properties for the remainder of the term of the Trust.

The following table sets forth the estimates of total proved reserves and forecasts of economics attributable to the Trust’s 80% net profits interest in the underlying properties as of December 31, 2025 for the remainder of the term of the Trust, as presented in the summary prepared by CG&A of its reserve report as of December 31, 2025 for the Trust. The estimates of proved reserves have not been filed with or included in reports to any federal authority or agency. The discounted cash flow value shown in the table is not intended to represent the current market value of the estimated oil and natural gas reserves attributable to the Trust’s interests.

The net profits interest entitles the Trust to receive 80% of the net proceeds attributable to MV Partners’ interest from the sale of production from the underlying properties. The net profits interest will terminate on June 30, 2026 because the minimum amount of production (14.4 MMBoe) applicable to the net profits interest has been produced and sold (which amount is the equivalent of 11.5 MMBoe with respect to the Trust’s net profits interest), and the Trust will soon thereafter wind up its affairs and terminate. See “Item 7. Trustee’s Discussion and Analysis of Financial Condition and Results of Operations — Termination of the Trust.” The reserve report reflects the termination of the net profits interest on June 30, 2026.

Oil and gas prices were adjusted to a WTI Cushing oil price of $65.34 per Bbl and a Henry Hub natural gas price of $3.387 per MMbtu. As specified by the SEC, these prices are 12-month averages based upon the price on the first day of each month during 2025. The price adjustments were based on oil price differentials forecast at -$4.50 per Bbl for all properties. Oil price differentials were not escalated. Gas and NGL price differentials were forecast on a per property basis as provided by MV Partners and were also not escalated. Price differentials include adjustments for transportation and basis differential. Gas prices were further adjusted with a heating value (Btu content) applied on a per-property basis. Operating expenses, workover expenses, COPAS overhead charges and investments were forecast on a per property basis as furnished by MV Partners. Expenses and investments were held constant in accordance with SEC rules and guidelines. Severance tax rates were applied at normal state percentages of oil and gas revenue, except for those Kansas producing properties that are severance tax exempt. Ad valorem taxes of 2.0% of total revenue were applied to each property as provided by MV Partners. Oil and gas conservation tax rates were applied to all Kansas properties at the applicable rates.

The estimates of proved oil and natural gas reserves attributable to the underlying properties are based on estimates prepared by CG&A. Rules and guidelines established by the SEC regarding the present value of future net revenues were used to prepare these reserve estimates. Oil and natural gas reserve engineering is a subjective process of estimating underground accumulations of oil and natural gas that cannot be measured in an exact manner and estimates of other engineers might differ materially from those included in the report. The accuracy of any reserve estimate is a function of the quality of available data and engineering, and estimates may justify revisions based on the results of drilling, testing, and production activities. Accordingly, reserve estimates are inherently imprecise and should not be construed as representing the actual quantities of future production or cash flows to be realized from oil and natural gas properties or the fair market value of such properties.

TABLE OF CONTENTS

Producing Acreage and Well Counts

For the following data, “gross” refers to the total wells or acres in which MV Partners owns a working interest and “net” refers to gross wells or acres multiplied by the percentage working interest owned by MV Partners. Although many of MV Partners’ wells produce both oil and natural gas, a well is categorized as an oil well or a natural gas well based upon the ratio of oil to natural gas production.

The underlying properties are interests in developed properties located in oil and natural gas producing regions of Kansas and eastern Colorado. The following is a summary of the approximate acreage of the underlying properties at December 31, 2025.

	Gross		Net

MV Partners did not drill any developmental wells or exploratory wells on the underlying properties during the years ended December 31, 2023, 2024 and 2025.

MV Partners did not drill, complete or commence production with respect to any wells on the underlying properties during the years ended December 31, 2023, 2024 and 2025. As of December 31, 2025, no wells were being drilled. There were no capital expenditures associated with converting proved undeveloped reserves to proved developed reserves for the year ended December 31, 2025. MV Partners continues to develop further proved undeveloped reserves pursuant to its planned development and workover program. See “Item 7. Trustee’s Discussion and Analysis of Financial Condition and Results of Operations — Planned Development and Workover Program.”

The following table shows the average sales prices per Bbl of oil and Mcf of natural gas produced and the production costs and production and property taxes per Boe for the underlying properties. Sales volumes for natural gas liquids during the periods presented were not significant.

TABLE OF CONTENTS

Major Producing Areas

Approximately 62% of the net acres included in the underlying properties are located in the El Dorado Area, which is located in southeastern Kansas, and in the Northwest Kansas Area. The underlying properties are all located in mature fields that are characterized by long production histories. The properties provide continual workover and developmental opportunities which MV Partners has pursued to reduce the natural decline in production from the underlying properties.

El Dorado Area

The underlying properties located in the El Dorado Area are operated on behalf of MV Partners by Vess Oil and are located in the El Dorado, Augusta and Valley Center Fields. Vess Oil has actively pursued infill drilling, well re-entries, plugback and deepening recompletion operations, various types of restimulation work and equipment optimization programs to reduce the natural decline in production from these fields.

El Dorado Field. The El Dorado Field is located atop the Nemaha Ridge in Central Butler County, Kansas and was first discovered in 1915. Up to 15 horizons have been reported to contain hydrocarbons, ranging from the Admire Sands, at a depth of 650 feet, to the Arbuckle Dolomite, at a depth of 2,500 feet. The primary producing intervals are the Admire, Lansing-Kansas City, Viola, Simpson and Arbuckle. Cumulative production of all producers from the El Dorado Field has exceeded 300 MMBbls of oil with production peaking between 1916 and 1918, reaching 116,000 Bbls per day in 1918.

Augusta Field. The Augusta Field is on a trend similar to the nearby El Dorado Field and strikes northeast parallel to the Nemaha Ridge. The field was discovered in 1914 and covers approximately 10 square miles of Butler County, Kansas. The primary producing interval has been the Arbuckle with additional production coming from the Simpson and Lansing-Kansas City intervals. Cumulative production of all producers from the Augusta Field has exceeded 48 MMBbls of oil. The Augusta Field is largely an extension of the El Dorado Field and has very similar geological characteristics.

Vess Oil has maintained constant activity in these fields to increase production. Vess Oil plans to maintain its annual recompletion and workover program over the next five years. Vess Oil has commenced a waterflood program to enhance production from the Whitecloud formation. Vess Oil plans to convert wells as the infill developmental drilling program proceeds.

Valley Center Field. The Valley Center Field was discovered in 1928 and covers approximately 60 square miles of Sedgwick County, Kansas. Production is primarily from the Viola interval, which is located at an average depth of 2,500 feet. Cumulative production of all producers from the Valley Center Field has exceeded 25 MMBbls of oil. The Valley Center Field has similar geological characteristics as the El Dorado Field.

Northwest Kansas Area

Each of Vess Oil and Murfin Drilling operate leases on behalf of MV Partners included in the underlying properties that are located in the Northwest Kansas Area. The primary fields in this area are the Bemis-Shutts, Trapp, Ray and Hansen Fields. Vess Oil and Murfin Drilling have actively pursued polymer treatments, stimulation workovers and recompletion operations to reduce the natural decline in production from these fields.

Bemis-Shutts Field. The Bemis-Shutts Field is located on the Fairport Anticline within the Central Kansas Uplift and was discovered in 1928. The field consists of 17,080 acres in northeastern Ellis and southeastern Rooks Counties, Kansas. Production has been from multiple pay zones with the primary formation being the Arbuckle interval at a depth of 3,300 feet and the Lansing-Kansas City interval at a depth of 2,800 feet. Cumulative production of all producers from the Bemis-Shutts Field has exceeded 248 MMBbls of oil.

Both Vess Oil and Murfin Drilling have pursued polymer treatment programs with success in the Bemis-Shutts Field and plan to continue these workovers. MV Partners has continued to acquire 3-D seismic surveys over portions of the field to further define the boundaries of the Arbuckle structure in the field and to evaluate undrilled infill locations.

TABLE OF CONTENTS

Trapp Field. The Trapp Field consists of 35,900 acres in Russell and Barton Counties, Kansas and was discovered in 1929. Production has primarily been from the Lansing-Kansas City and Shawnee limestones and the Arbuckle dolomite. Cumulative production of all producers from the Trapp Field has exceeded 239 MMBbls of oil.

Hansen and Ray Fields. The Hansen Field is located along the crest of the Stuttgart-Huffstutor Anticline and was discovered in 1943. Production from this field has primarily come from the Lansing- Kansas City limestone. Cumulative production of all producers from the Hansen Field has exceeded 9.2 MMBbls of oil.

The Ray Field is located on the eastern flank of the Central Kansas Uplift and was discovered in 1940. Production has primarily been from the Arbuckle dolomite and the Gorham sands with additional production from the Lansing-Kansas City interval along the eastern flank of the field. Cumulative production of all producers from the Ray Field has exceeded 18 MMBbls of oil.

The Hansen and Ray Fields consist of over 7,000 acres in Philips and Norton Counties, Kansas.

Murfin Drilling operates the leases held by MV Partners in the Trapp, Hansen and Ray Fields. Murfin Drilling has informed the Trustee that it plans to workover and recomplete additional wells, including acid stimulations, over the next five years.

Marketing and Post-Production Services

Pursuant to the terms of the Conveyance, MV Partners has the responsibility to market, or cause to be marketed, the oil, natural gas and natural gas liquid production attributable to the underlying properties. The terms of the Conveyance do not permit MV Partners to charge any marketing fee when determining the net proceeds upon which the net profits interest is calculated. As a result, the net proceeds to the Trust from the sales of oil, natural gas and natural gas liquid production from the underlying properties are determined based on the same price that MV Partners receives for oil, natural gas and natural gas liquid production attributable to MV Partners’ remaining interest in the underlying properties.

Vess Oil and Murfin Drilling, as contract operators, generally sell production from the underlying properties to several purchasers, including MV Purchasing, LLC (“MV Purchasing”), under short-term arrangements using market-sensitive pricing. MV Purchasing is majority-owned by the indirect equity owners of MV Partners. These sales to purchasers are under terms ranging from one month to six months, using market sensitive pricing. Two purchasers, including MV Purchasing, have been purchasing substantially all of the crude oil production, and a substantial portion of the crude oil production may continue be acquired by one or more single purchasers. For the years ended December 31, 2023, 2024 and 2025, MV Purchasing purchased 73%, 74% and 74%, respectively, of the production sold from the underlying properties. MV Partners does not believe that loss of any of these parties as a purchaser would have a material adverse impact on the business of MV Partners, as substitute purchasers are generally available; however, a purchaser’s failure to pay for purchased crude oil could have a significant adverse impact on MV Partners’ business.

Oil production is typically transported by truck from the field to the closest gathering facility or refinery. MV Partners sells the majority of the oil production from the underlying properties under short-term arrangements using market sensitive pricing. The price received by MV Partners for the oil production from the underlying properties is usually based on the NYMEX price applied to equal daily quantities on the month of delivery, which price is then reduced for differentials based upon delivery location and oil quality. The average differential for oil production during the years ended December 31, 2023, 2024 and 2025 was $4.13, $3.91 and $3.89 per barrel, respectively.

All natural gas produced by MV Partners is marketed and sold to third-party purchasers. The natural gas is sold on a contract basis and, in all but one case, the contracts are in their secondary terms and are on a month-to-month basis. In all cases, the contract price is based on a percentage of a published regional index price, after adjustments for Btu content, transportation and related charges.

TABLE OF CONTENTS

Sale and Abandonment of Underlying Properties

MV Partners and any transferee of any of the underlying properties will have the right to abandon its interest in any well or property comprising a portion of the underlying properties if, in its opinion, such well or property ceases to produce or is not capable of producing in commercially paying quantities. To reduce or eliminate the potential conflict of interest between MV Partners and the Trust in determining whether a well is capable of producing in commercially paying quantities, MV Partners is required under the Conveyance to act as a reasonably prudent operator in the State of Kansas under the same or similar circumstances would act if it were acting with respect to its own properties, disregarding the existence of the net profits interest as a burden on such property. For the years ended December 31, 2023, 2024 and 2025, MV Partners plugged and abandoned 4, 7 and 27 wells, respectively, based on its determination that such wells were no longer economical to operate or restore to production.

MV Partners generally may sell all or a portion of its interests in the underlying properties, subject to and burdened by the net profits interest, without the consent of the Trust unitholders. In addition, MV Partners may, without the consent of the Trust unitholders, require the Trust to release the net profits interest associated with any lease that accounts for no more than 0.25% of the total production from the underlying properties in the prior 12 months and provided that the net profits interest covered by such releases cannot exceed, during any 12-month period, an aggregate fair market value to the Trust of $500,000. These releases will be made only in connection with a sale by MV Partners to a non-affiliate of the relevant underlying properties and are conditioned upon the Trust receiving an amount equal to the fair value to the Trust of such net profits interest. Any net sales proceeds paid to the Trust are distributable to Trust unitholders for the quarter in which they are received.

Title to Properties

The underlying properties are subject to certain burdens that are described in more detail below. To the extent that these burdens and obligations affect MV Partners’ rights to production and the value of production from the underlying properties, they have been taken into account in calculating the Trust’s interests and in estimating the size and the value of the reserves attributable to the underlying properties.

MV Partners’ interests in the underlying properties are typically subject, in one degree or another, to one or more of the following:

•

royalties, overriding royalties and other burdens, express and implied, under oil and natural gas leases;

•

overriding royalties, production payments and similar interests and other burdens created by MV Partners or its predecessors in title;

•

a variety of contractual obligations arising under operating agreements, farm-out agreements, production sales contracts and other agreements that may affect the underlying properties or their title;

•

liens that arise in the normal course of operations, such as those for unpaid taxes, statutory liens securing unpaid suppliers and contractors and contractual liens under operating agreements that are not yet delinquent or, if delinquent, are being contested in good faith by appropriate proceedings;

•

pooling, unitization and communitization agreements, declarations and orders;

•

easements, restrictions, rights-of-way and other matters that commonly affect property;

•

conventional rights of reassignment that obligate MV Partners to reassign all or part of a property to a third party if MV Partners intends to release or abandon such property; and

•

rights reserved to or vested in the appropriate governmental agency or authority to control or regulate the underlying properties and the net profits interest therein.

MV Partners has informed the Trustee that MV Partners believes that the burdens and obligations affecting the underlying properties are conventional in the industry for similar properties. MV Partners also has informed the Trustee that MV Partners believes that the existing burdens and obligations do not, in

TABLE OF CONTENTS

the aggregate, materially interfere with the use of the underlying properties and do not materially adversely affect the value of the net profits interest.

MV Partners acquired the underlying properties in two transactions, the first of which was in 1998 when it acquired a substantial portion of the underlying properties from a major oil and gas company and the second of which was in 1999 when it acquired the remaining portion of the underlying properties from a large independent oil and gas company. At the time of its acquisition of the underlying properties, MV Partners believes that it undertook a thorough title examination of the underlying properties.

MV Partners has recorded the Conveyance in the real property records in each Kansas County where the properties are located. MV Partners has informed the Trustee that MV Partners believes that the delivery and recording of the Conveyance constituted fully conveyed and vested property interests in the Trust under Kansas law. Although no assurance can be given, MV Partners has informed the Trustee that MV Partners believes that, if, during the term of the Trust, MV Partners becomes involved as a debtor in a bankruptcy proceeding, the Conveyance, as vested and recorded property interests, cannot be avoided by a bankruptcy Trustee. If in such a proceeding a determination were made that the Conveyance constitutes an executory contract and the net profits interest is not a fully conveyed property interest under the laws of Kansas, and if such contract were not to be assumed in a bankruptcy proceeding involving MV Partners, the Trust would be treated as an unsecured creditor of MV Partners with respect to such net profits interest in the pending bankruptcy proceeding.

Oil and gas leases are real property interests under Colorado law. Net profits interests are non-operating, non-possessory interests carved out of the oil and gas leasehold estate. MV Partners has informed the Trustee that MV Partners believes that it is possible that the net profits interest for the underlying properties located in Colorado may not be treated as a real property interest under the laws of Colorado. MV Partners has recorded the Conveyance in the real property records of Colorado in accordance with local recording acts. MV Partners has informed the Trustee that MV Partners believes that if, during the term of the Trust, MV Partners becomes involved as a debtor in a bankruptcy proceeding, the net profits interest relating to the underlying properties located in Colorado should be treated as a fully conveyed personal property interest under the laws of Colorado. In such a proceeding, however, a determination could be made that the Conveyance constitutes an executory contract and the net profits interest is not a fully conveyed personal property interest under the laws of Colorado, and if such contract were not to be assumed in a bankruptcy proceeding involving MV Partners, the Trust would be treated as an unsecured creditor of MV Partners with respect to such net profits interest in the pending bankruptcy proceeding. Although no assurance can be given, MV Partners does not believe that the conveyance of the net profits interest relating to the underlying properties located in Colorado should be subject to rejection in a bankruptcy proceeding as an executory contract.

Competition and Markets

The oil and natural gas industry is highly competitive. MV Partners competes with major oil and natural gas companies and independent oil and natural gas companies for oil and natural gas, equipment, personnel and markets for the sale of oil and natural gas. Many of these competitors are financially stronger than MV Partners, but even financially troubled competitors can affect the market because of their need to sell oil and natural gas at any price to attempt to maintain cash flow. The Trust is subject to the same competitive conditions as MV Partners and other companies in the oil and natural gas industry.

Oil and natural gas compete with other forms of energy available to customers, primarily based on price. These alternate forms of energy include electricity, coal and fuel oils. Changes in the availability or price of oil, natural gas or other forms of energy, as well as business conditions, conservation, legislation, regulations and the ability to convert to alternate fuels and other forms of energy may affect the demand for oil and natural gas.

Future price fluctuations for oil, natural gas and natural gas liquids will directly impact Trust distributions, estimates of reserves attributable to the Trust’s interests and estimated and actual future net revenues to the Trust. In view of the many uncertainties that affect the supply and demand for oil and natural gas, neither the Trust nor MV Partners can make reliable predictions of future oil and natural gas supply and demand, future product prices or the effect of future product prices on the Trust.

TABLE OF CONTENTS

Regulation

The production of oil and gas from the underlying properties is affected by many state and federal regulations with respect to allowable rates of production, drilling permits, well spacing, marketing, environmental matters and pricing. Future regulations could change allowable rates of production or the manner in which oil and gas operations may be lawfully conducted.

FERC Regulation

Historically, the transportation and sale for resale of natural gas in interstate commerce has been regulated by the Federal Energy Regulatory Commission, or the “FERC,” under the Natural Gas Act of 1938, or NGA, the Natural Gas Policy Act of 1978, or “NGPA,” and regulations issued under those statutes. Over the last two decades, the FERC has issued orders and adopted regulations resulting in a restructuring of the natural gas industry. The principal elements of this restructuring were the requirement that interstate pipelines separate, or “unbundle,” into individual components the various services offered on their systems, with all transportation services to be provided on a non-discriminatory basis, and the prohibition against an interstate pipeline providing gas sales services except through separately organized affiliates. In various rulemaking proceedings following its initial unbundling requirement, the FERC has refined its regulatory program applicable to interstate pipelines in various respects, and it has announced that it will continue to monitor these and other regulations to determine whether further changes are needed. In addition to rulemaking proceedings, the FERC establishes new policies and regulations through policy statements and adjudications of individual pipeline matters. Further, additional changes to regulations may occur based on actions taken by the United States Congress and/or the courts.

In the past, the federal government has regulated the prices at which natural gas could be sold. While sales by producers of natural gas can currently be made at market prices, Congress could reenact price controls in the future. Deregulation of wellhead natural gas sales began with the enactment of the NGPA and culminated in adoption of the Natural Gas Wellhead Decontrol Act which removed all price controls affecting wellhead sales of natural gas effective January 1, 1993.

Sales of crude oil, condensate, and natural gas liquids are not currently regulated and are made at negotiated prices. Nevertheless, Congress could reenact price controls in the future. Sales of crude oil are affected by the availability, terms and cost of transportation. The transportation of oil in common carrier pipelines is subject to rate and access regulation. The FERC regulates interstate oil pipeline transportation rates under the Interstate Commerce Act. In general, interstate oil pipeline rates must be just and reasonable and may not be unduly discriminatory or confer any undue preference upon any shipper. Rates generally are cost-based, although settlement rates agreed to by all shippers are permitted and market-based rates may be permitted in certain circumstances.

Although the price at which MV Partners sells oil, natural gas and natural gas liquids is not currently subject to federal rate regulation and, for the most part, is not subject to state regulation, with regard to physical sales of natural gas and oil, MV Partners is required to observe anti-market manipulation laws and related regulations enforced by the FERC and/or the Commodity Futures Trading Commission and the Federal Trade Commission. If MV Partners were to violate the anti-market manipulation laws and regulations, MV Partners could also be subject to related third-party damage claims by, among others, sellers, royalty owners and taxing authorities.

As to these various developments, MV Partners has advised the Trust that the on-going and evolving nature of these regulatory initiatives makes it impossible to predict their ultimate impact on the prices, markets or terms of sale of natural gas related to the Trust.

State and Other Regulation

In general, the jurisdictions in which royalty properties are located have statutory provisions regulating the production and sale of crude oil and natural gas. The regulations often require permits for the drilling of wells but extend also to the spacing of wells, the prevention of waste of oil and gas resources, the rate of production, prevention and clean-up of pollution and other matters.

TABLE OF CONTENTS

Environmental Matters and Regulation

General. The operations of the underlying properties are subject to stringent and complex federal, state and local laws and regulations governing environmental protection as well as the discharge of materials into the environment. These laws and regulations may, among other things:

•

restrict the types, quantities and concentration of various substances that can be released or emitted into the environment in connection with oil and natural gas drilling and production activities;

•

limit or prohibit construction or drilling activities on certain lands lying within wilderness, wetlands and other protected areas; and

•

require investigatory and remedial measures to mitigate pollution from former and ongoing operations, such as requirements to close pits and plug abandoned wells.

These laws, rules and regulations may also restrict the rate of oil and natural gas production below the rate that would otherwise be possible. The regulatory burden on the oil and natural gas industry increases the cost of doing business in the industry and consequently affects profitability. Additionally, Congress and federal and state agencies frequently revise environmental laws and regulations, and any changes that result in more stringent and costly waste handling, disposal and cleanup requirements for the oil and natural gas industry could have a significant impact on the operating costs of the underlying properties.

The following is a summary of the existing laws, rules and regulations to which the operations of the underlying properties are subject that are material to the operation of the underlying properties.

Hazardous Substances and Wastes. The Comprehensive Environmental Response, Compensation, and Liability Act, as amended (“CERCLA”), also known as the Superfund law, and comparable state laws impose liability without regard to fault or the legality of the original conduct on certain classes of persons who are considered to be jointly and severally responsible for the release of a “hazardous substance” into the environment. These persons include current and prior owners or operators of the site where the release occurred and entities that disposed or arranged for the disposal of the hazardous substances found at the site. Under CERCLA, these “responsible persons” may be liable for the costs of cleaning up the hazardous substances that have been released into the environment, for damages to natural resources, and for the costs of certain health studies. CERCLA also authorizes the U.S. Environmental Protection Agency (“EPA”) and, in some instances, third parties to act in response to threats to the public health or the environment and then to seek to recover from the responsible classes of persons the costs they incur. It is not uncommon for neighboring landowners and other third parties to file claims for personal injury and property damage allegedly caused by the release of hazardous substances or other pollutants into the environment. Although petroleum, natural gas, and natural gas liquids are excluded from the definition of “hazardous substance” under CERCLA, MV Partners handles materials in the course of its operations that may be regulated as CERCLA hazardous substances, despite the so-called “petroleum exclusion.”

MV Partners also generates solid and hazardous wastes that are subject to the requirements of the Resource Conservation and Recovery Act, as amended (“RCRA”), and comparable state statutes. RCRA imposes strict requirements on the generation, storage, treatment, transportation and disposal of hazardous wastes. In the course of its operations, MV Partners generates petroleum hydrocarbon wastes and ordinary industrial wastes that may be classified as hazardous wastes under RCRA and comparable state laws. Drilling fluids, produced waters, and most of the other wastes associated with the exploration, production, and development of crude oil or natural gas are currently regulated under RCRA as non-hazardous wastes. While many exploration and production wastes are exempt from regulation as hazardous waste, these wastes are generally subject to non-hazardous waste regulation under RCRA and applicable state regulations. Many state governments have specific regulations and guidance for exploration and production wastes, including the wastes associated with hydraulic fracturing activities.

MV Partners currently owns or leases, and in the past may have owned or leased, properties that have been used for numerous years to explore and produce oil and natural gas. Although MV Partners may have utilized operating and disposal practices that were standard in the industry at the time, hydrocarbons and wastes may have been disposed of or released at or from the properties owned or leased by MV Partners or at or from the other locations where these hydrocarbons and wastes have been taken for treatment or disposal.

TABLE OF CONTENTS

In addition, certain of these properties have been operated by third parties whose treatment and disposal or release of hydrocarbons and wastes was not under MV Partners’ control. These properties and wastes disposed thereon may give rise to liability under CERCLA, RCRA and analogous state laws. Under these laws, MV Partners could be required to investigate, remove or remediate previously disposed wastes, to clean up contaminated property and to perform response actions to prevent future contamination.

Water Discharges. The federal Clean Water Act (“CWA”) and analogous state laws impose restrictions and strict controls on the discharge of pollutants into “waters of the United States” and waters within the scope of state law, respectively. Pursuant to the CWA and applicable state laws, permits must be obtained to discharge pollutants into regulated waters. Any such discharge of pollutants into regulated waters must be performed in accordance with the terms of the permit issued by the EPA or the applicable state agency or both. The discharge of wastewater from most onshore oil and gas activities exploration and production activities is currently prohibited east of the 98th meridian. Additionally, in June 2016, the EPA issued a final rule implementing wastewater pretreatment standards that prohibit onshore unconventional oil and natural gas extraction facilities from sending wastewater directly to publicly owned treatment works (“POTW”). Unconventional extraction facilities are in certain circumstances allowed by federal regulations to send wastewater to an off-site private centralized wastewater treatment (“CWT”) facility in most circumstances. CWT facilities can either discharge treated water directly to surface waters or send it to a POTW. In 2018, the EPA concluded a study of the treatment and discharge of oil and gas wastewater that could lead to changes in requirements for discharge of produced water under federal regulations, including more stringent requirements or a prohibition on discharge of produced water from CWT facilities. Any restriction of disposal options for hydraulic fracturing waste and other changes to CWA discharge requirements may result in increased costs.

The discharge of dredge and fill material in waters of the United States, including wetlands, is also prohibited unless authorized by a permit issued under CWA Section 404 by the U.S. Army Corps of Engineers (“USACE”). CWA Section 401 provides that the applicant for a Section 404 USACE permit for the discharge of dredge and fill material must seek a Section 401 water quality certification by applying to the state in which the discharge will occur for the state to determine if the discharge will comply with the state’s approved water quality program. In some instances, this process could result in a delay in issuance of the permit, more stringent permit requirements, or denial of the permit.

How the EPA and the USACE define “waters of the United States” (“WOTUS”), which defines the extent of geographic jurisdiction under the CWA, has been the subject of controversy and litigation for decades and can impact MV Partners’ regulatory and permitting obligations under the CWA. In 2023, in Sackett v. EPA, the Supreme Court issued a landmark decision interpreting WOTUS more narrowly than the then-current definition contemplated, resulting in diminished jurisdiction over wetlands and streams that lacked certain connections to other waters or consistent water flow. Following Sackett, because of ongoing litigation, the regulatory landscape currently remains unsettled. The regulations currently in effect in 24 states define WOTUS using a 2023 regulation modified after the Sackett decision. In the rest of the country, the agencies base jurisdiction on an earlier WOTUS definition as implemented in light of a number of Supreme Court decisions, including Sackett. Despite the two approaches, jurisdiction over WOTUS is essentially consistent across the United States.

In November 2025, the USACE released a proposed rule revising the regulatory definition of WOTUS. That new definition is expected to go into effect in early 2026 without substantial changes from the proposed definition. Regardless of the ultimate details, the revised definition likely will further reduce CWA jurisdiction, especially over wetlands and streams, leading to fewer permitting requirements. Once the new WOTUS definition is final, litigation will likely continue challenging the legality of the definition. This litigation could have the effect of delaying or precluding implementation of the new rule. MV Partners’ regulatory obligations and permitting costs will continue to be subject to remaining uncertainty around the definition of WOTUS and the scope of CWA regulation, given the ongoing litigation.

USACE Nationwide Permits (“NWPs”) are a streamlined form of permitting used to authorize activities related to development activities with minimal individual or cumulative adverse effects in wetlands or other waters of the United States under the CWA. Some NWPs are also used to authorize activities that impact traditional navigable waters under the Rivers and Harbors Act. The NWPs expire in March 2026

TABLE OF CONTENTS

and will be replaced, simultaneously, with new versions that are largely unchanged from the previous set. Litigation challenging the NWPs, if filed, could result in additional cost and time for permitting projects.

In February 2025, the USACE began implementing emergency permitting procedures as directed by President Trump’s Executive Order Declaring a National Energy Emergency. This has resulted, in many instances, in substantially decreased timeframes for receiving Section 404 permits in the case of energy projects subject to the Executive Order.

The Oil Pollution Act of 1990, as amended (“OPA”), which amends the CWA, establishes standards for prevention, containment and cleanup of oil spills into waters of the United States. The OPA requires measures to be taken to prevent the accidental discharge of oil into waters of the United States from onshore production facilities. Measures under the OPA and the CWA include inspection and maintenance programs to minimize spills from oil storage and conveyance systems; the use of secondary containment systems to prevent spills from reaching nearby waterbodies; proof of financial responsibility to cover environmental cleanup and restoration costs that could be incurred in connection with an oil spill; and the development and implementation of spill prevention, control and countermeasure (“SPCC”) plans to prevent and respond to oil spills. The OPA also subjects owners and operators of facilities to strict, joint and several liability for all containment and cleanup costs and certain other damages arising from a spill. MV Partners has developed and implemented SPCC plans for the underlying properties as required under the CWA.

Air Emissions. The Clean Air Act, as amended (“CAA”), and comparable state laws and regulations restrict the emission of air pollutants from many sources and also impose various monitoring and reporting requirements. These laws and regulations may require MV Partners to obtain pre-approval for the construction or modification of certain projects or facilities expected to produce or significantly increase air emissions, and to comply with stringent air permit or regulatory requirements or utilize specific equipment or technologies to control emissions. Obtaining permits has the potential to delay the development of MV Partners’ properties.

The EPA has established pollution control standards for oil and gas sources under the CAA. In 2012 and 2016, the EPA adopted federal New Source Performance Standards (“NSPS”) that require the reduction of volatile organic compound and sulfur dioxide emissions from certain fractured and refractured natural gas wells for which well completion operations are conducted and further require that most wells use reduced emission completions, also known as “green completions.” These regulations also establish specific requirements regarding emissions from production-related wet seal and reciprocating compressors, pumps, and from pneumatic controllers and storage vessels, and for equipment leaks. These NSPS apply to sources that are newly constructed or modified after the rules’ applicability dates. More recently, the EPA adopted a final rule in 2024 that will directly regulate volatile organic compound and methane emissions from oil and gas sources constructed or modified after December 2022 and will require reductions in both pollutants through its regulation of flaring, compressors, pumps, storage vessels, process controllers, well completions and liquids unloading, and equipment leaks. Additionally, the EPA for the first time adopted emissions guidelines that will apply to existing oil and gas sources and that require reductions in volatile organic compound and methane emissions that are largely equivalent to the requirements for new sources. The existing source emissions guidelines are to be implemented through state plans, with expected compliance dates for existing sources arriving in 2029.

The results of the 2024 presidential election and President Trump’s energy agenda prioritizing domestic oil and gas production likely will impact the air quality-related requirements that apply to MV Partners. In March 2025, the EPA announced it was reconsidering the 2024 rules that established new volatile organic compound and methane emissions standards for both new and existing sources. Following that announcement, the EPA adopted amendments to the NSPS and existing source performance standards that extended the compliance deadlines for many of the new source requirements adopted in 2024 and extended the state plan submittal deadlines, which will effectively extend the dates by which existing sources must come into compliance with the existing source emissions guidelines. It is currently unknown whether the EPA’s reconsideration of the 2024 rules will result in further changes. Similar to prior changes to the air pollution control standards for oil and gas sources, the most recent changes will be subject to judicial review, as well as the potential for future presidential administrations to take a different approach.

TABLE OF CONTENTS

The EPA is also charged with establishing National Ambient Air Quality Standards (“NAAQS”), the implementation of which can indirectly impact MV Partners’ operations. The CAA directs the EPA to review each NAAQS every five years to ensure that the standards are protective of public health and welfare. This process routinely results in the tightening of those standards, and in October 2015, the EPA lowered the ozone NAAQS from 75 to 70 parts per billion. In December 2020, the EPA published a final rule that retained without revision the 2015 NAAQS ozone standard. Likewise, in March 2024, the EPA issued a final rule that lowered the annual standard for fine particulate matter from 12 to 9 micrograms per cubic meter. In March 2025, however, the EPA announced that it would reconsider the rule lowering the fine particulate matter standard, and the EPA has filed a request that the U.S. Court of Appeals vacate the 2024 rule. In 2026, the EPA also has delayed taking certain actions necessary to implement air quality requirements under the lower 2024 standard. No regulatory action or court decision has changed the 2024 rule lowering the fine particulate matter standard, and the EPA’s delayed implementation of the 2024 standard likely will be subject to judicial review. State or federal implementation of the NAAQS could result in stricter permitting or regulatory requirements, delay or prohibit MV Partners’ ability to obtain such permits, and result in increased expenditures for pollution control equipment.

MV Partners may be required to incur certain capital expenditures for air pollution control equipment or other air emissions-related issues. MV Partners currently does not expect that such requirements will have a material adverse effect on its operations.

Climate Change. The Trump Administration’s efforts to roll back federal regulation of greenhouse gases (“GHGs”) represent a significant shift in federal climate policy, though the ultimate impact of those efforts on MV Partners is unclear. In 2009, the EPA found that emissions of carbon dioxide, methane and GHGs may present an endangerment to public health and the environment and subsequently issued regulations to restrict emissions of greenhouse gases under existing provisions of the CAA. These regulations include limits on tailpipe emissions from motor vehicles, preconstruction and operating permit requirements for certain large stationary sources, and methane emissions standards for certain new, modified and reconstructed oil and gas sources — as well as the EPA’s methane emissions guidelines for existing oil and gas sources that were adopted in 2024. The EPA also has adopted rules requiring the reporting of GHG emissions from specified large greenhouse gas emission sources in the United States, as well as certain onshore oil and natural gas production facilities, on an annual basis. Shortly after President Trump took office in January 2025, the federal government embarked on a series of changes relating to climate policy and regulation. On January 20, 2025, President Trump announced the withdrawal of the United States from the Paris Climate Agreement. In July 2025, the EPA issued a proposed rule to rescind the 2009 GHG endangerment finding that provided a basis for GHG regulation under the CAA. In September 2025, the EPA proposed to rescind the GHG reporting program for sectors other than the oil and gas sector, while proposing to suspend GHG reporting requirements for the oil and gas sector until 2034. In February 2026, the EPA adopted a final rule repealing its prior endangerment finding, which opens the door for the EPA to repeal its GHG rules for the oil and gas sector.

The EPA has established methane standards for oil and gas sources based on the now-repealed GHG endangerment finding. In 2024, the EPA adopted a final rule that will directly regulate volatile organic compound and methane emissions from new oil and gas sources and will require reductions in methane and volatile organic compound emissions through its regulation of flaring, compressors, pumps, storage vessels, process controllers, well completions and liquids unloading, and equipment leaks. At the same time, the EPA adopted emissions guidelines that will apply to existing oil and gas sources and that require reductions in volatile organic compound and methane emissions that are largely equivalent to the requirements for new sources. The existing source emissions guidelines are to be implemented through state plans, with expected compliance dates arriving in 2029. In 2025, however, the EPA extended certain compliance deadlines for both new and existing sources, and the 2026 endangerment finding repeal provides a basis for undoing the oil and gas methane standards — though the fact that the oil and gas standards address both methane and volatile organic compounds, which are regulated independently of the EPA’s authority to regulate GHGs, may limit the impact of future changes to the methane standards that currently apply to oil and gas sources.

The Inflation Reduction Act (the “IRA”) included new Clean Air Act section 136(c) directing the EPA to collect the Waste Emissions Charge (“WEC”) from facilities in the oil and gas sector that report more than 25,000 tons of carbon dioxide equivalent emissions in a calendar year. The charge will first apply to

TABLE OF CONTENTS

methane emissions from calendar year 2024. The charge is determined by comparing actual reported methane emissions to statutorily established “methane intensity figures” that are based on gas production or throughput, with a charge assessed for every ton of methane emissions that exceeds the facility’s allowable emissions based on the applicable methane intensity figure. The charge will be $900 per ton for 2024 emissions and will increase to $1,200 and then $1,500 per ton in subsequent years. The program includes key exemptions, most notably a regulatory compliance exemption that applies to and exempts the emissions from facilities that are subject to and in complete compliance with EPA’s new or existing source methane requirements. The EPA adopted new rules to implement the WEC program in November 2024; however, the fate of the WEC and the EPA rules implementing the WEC is unclear. In March 2025, President Trump signed legislation repealing the EPA’s 2024 WEC rules under the Congressional Review Act. The repeal of EPA’s WEC rules did not eliminate the statutory requirement to pay the WEC, but it eliminated the rules established by the EPA to determine the WEC due, the payment mechanism, and any payment deadlines. The U.S. Congress may be considering amendment or repeal of certain portions of the IRA, including the statutory provisions establishing the WEC.

Meanwhile, more than one third of the states have begun taking actions to control and/or reduce emissions of GHGs, primarily through the planned development of GHG emission inventories and/or regional GHG cap and trade programs. Although most of the state level initiatives to date have focused on large sources of GHG emissions, such as coal fired electric plants, it is possible that smaller sources of emissions could become subject to GHG emission limitations or allowance purchase requirements in the future. For example, the states of Colorado and New Mexico have adopted rules regulating GHGs from the oil and gas industry that are based on the federal standards. Congress may in the future consider adopting other legislation to reduce emissions of greenhouse gases. Any one of these climate change regulatory and legislative initiatives could have a material adverse effect on MV Partners’ business, capital expenditures, financial condition and results of operations.

The adoption and implementation of regulations imposing reporting obligations on, or limiting emissions of GHGs from, MV Partners’ equipment and operations could require MV Partners to incur costs to reduce emissions of GHGs associated with its operations or could adversely affect demand for the oil and natural gas it produces. Legislation or regulations that may be adopted to address climate change could also affect the markets for MV Partners’ products by making its products more or less desirable than competing sources of energy. To the extent that its products are competing with higher GHG-emitting energy sources, MV Partners’ products may become more desirable in the market with more stringent limitations on GHG emissions. To the extent that its products are competing with lower GHG-emitting energy, MV Partners’ products may become less desirable in the market with more stringent limitations on greenhouse gas emissions. MV Partners cannot predict with any certainty at this time how these possibilities may affect its operations.

The operations of the underlying properties are not adversely impacted by the current state and local climate change initiatives and, at this time, it is not possible to accurately estimate how potential future laws or regulations addressing greenhouse gas emissions would impact the operations of the properties.

Finally, some scientists have theorized that increasing concentrations of GHGs in the Earth’s atmosphere may produce climate changes that have significant physical effects, such as increased frequency and severity of storms, droughts, and floods and other climatic events. If any such significant physical effects were to occur, they could have an adverse effect on MV Partners’ assets and operations and cause MV Partners to incur costs in preparing for and responding to them. Additionally, energy needs could increase or decrease as a result of extreme weather conditions, depending on the duration and magnitude of those conditions.

Endangered Species Act. The federal Endangered Species Act, as amended (“ESA”), prohibits taking of listed endangered, and in some cases threatened, species. Under the ESA, federal agencies are obligated to consult with the U.S. Fish and Wildlife Service or National Marine Fisheries Service (the “Services”) if an agency’s actions, including permit actions, may affect listed species or designated critical habitat. If endangered species are located in areas of the Underlying Properties where seismic surveys, development activities or abandonment operations may be conducted, the work could be prohibited or delayed or expensive mitigation may be required, depending on the implications for protected species and designated critical habitat. Changes to implementing rules in the Biden Administration may, in some instances, make a federal review process occasioned by the application for permits, rights of way, or leases more

TABLE OF CONTENTS

complex in certain circumstances. In addition, designation of new species as threatened or endangered could cause MV Partners to incur additional costs arising from species protection measures, could result in limitations on activities, and could require a more complex regulatory compliance process. However, in 2025, the Services issued proposed revisions to the regulations implementing the ESA Section 7 consultation process and the scope of the definition of the term “take.” These regulations, if finalized, generally would be deregulatory in nature, modestly reducing the coverage of the ESA and streamlining the ESA section 7 consultation process. Nevertheless, these rules are expected to be immediately challenged in litigation, which will create uncertainty as to if and when these rules will go into effect. In January 2025, the Trump Administration directed the use of the emergency consultation procedures for permitting for energy projects in the Declaring a National Energy Emergency Executive Order.

National Environmental Policy Act. The National Environmental Policy Act (“NEPA”) requires the federal government to undertake an environmental review prior to making a decision on most proposed federal actions — such as permits, leases, and rights-of-way. Driven by court decisions and Administration policy, NEPA implementation and resulting litigation changed dramatically in 2025. Key changes are driving agencies narrow their NEPA reviews and complete them faster and are driving courts to show more deference to agencies when reviewing the adequacy of an agency’s analysis under NEPA, benefitting private projects that may require federal permits and reviews.

In particular, until 2025, agencies undertook NEPA reviews pursuant to binding regulations issued by the White House Council on Environmental Quality (“CEQ”) as well as pursuant to the federal agency’s own NEPA procedures. After two federal courts found that CEQ did not have authority to issue binding regulations, CEQ withdrew their regulations. In their place, agencies each issued their own NEPA procedures and, for the most part, put those procedures in agency guidance rather than binding regulations, although the USACE (which issues permits that can be critical to construction) regulatory program is a notable exception, keeping its NEPA procedures in regulations. While the agency procedures were based on a CEQ template, there are inconsistencies among the agencies on various topics, including the requirement for public comment and consideration of various types of impacts. These procedures make changes that are intended to streamline reviews.

Also, on May 29, 2025, the Supreme Court decided Seven County Infrastructure Coalition v. Eagle County, Colorado, in which the Court expressed clear intention that NEPA should be brought “back in line with the statutory text and common sense.” Significantly for permits that may be needed for private projects, the Court clarified that agencies need only evaluate the effects of the specific “proposed action” before them, not the impacts of “other future or geographically separate projects that may be built (or extended) as a result of or in the wake of the immediate project under consideration.” The Court also emphasized that courts must afford agencies substantial deference in reviewing agency actions under NEPA and that agencies “must have broad latitude to draw a ‘manageable line’” when determining the appropriate scope of analysis. The Court’s decision may reduce litigation risk and help streamline federal reviews.

OSHA and Other Laws and Regulation. MV Partners is subject to the requirements of the federal Occupational Safety and Health Act (“OSHA”) and comparable state statutes, whose purpose is to protect the health and safety of workers. In addition, the OSHA hazard communication standard, the EPA community right-to-know regulations under Title III of CERCLA and comparable state statutes require in certain circumstances that information be maintained concerning hazardous materials used or produced in MV Partners’ operations and that this information be provided to employees, state and local government authorities and citizens. MV Partners believes that it is in substantial compliance with these applicable requirements and with other OSHA and comparable requirements.

MV Partners believes that it is in substantial compliance with all existing environmental laws and regulations applicable to the current operations of the underlying properties and that its continued compliance with existing requirements will not have a material adverse effect on the cash distributions to the Trust unitholders. For instance, MV Partners did not incur any material capital expenditures for remediation or pollution control activities for the years ended December 31, 2023, 2024 and 2025.

Additionally, MV Partners has informed the Trust that MV Partners is not aware of any environmental issues or claims that will require material capital expenditures during 2026. Nevertheless, the passage of more

TABLE OF CONTENTS

stringent laws or regulations in the future could have a negative impact on the operations of the underlying properties and cash distributions to Trust unitholders.

Item 1A. Risk Factors

Operating Risks

Prices of oil, natural gas and natural gas liquids fluctuate, and lower prices could reduce proceeds to the Trust and cash distributions to Trust unitholders.

The reserves attributable to the underlying properties and the quarterly cash distributions of the Trust are highly dependent upon the prices realized from the sale of oil, natural gas and natural gas liquids. Prices of oil, natural gas and natural gas liquids can fluctuate widely on a quarter-to-quarter basis in response to a variety of factors that are beyond the control of the Trust and MV Partners. These factors include, among others:

•

regional, domestic and foreign supply and perceptions of supply of oil, natural gas and natural gas liquids;

•

the level of demand and perceptions of demand for oil, natural gas and natural gas liquids;

•

political conditions or hostilities in oil and natural gas producing regions, including the Middle East, North Africa and South America;

•

the ongoing wars in Ukraine and in the Persian Gulf, and the potential destabilizing effects such conflicts may pose for the global oil and gas markets;

•

the occurrence or threat of epidemic or pandemic diseases or other public health events or any government response to such occurrence or threat;

•

the actions of OPEC, its members and other oil-producing nations, such as Russia, relating to oil price and production levels, including announcements of potential changes to such levels;

•

the levels of production of oil and natural gas of non-OPEC countries;

•

anticipated future prices of oil and natural gas and other commodities;

•

weather conditions and seasonal trends;

•

technological advances affecting energy consumption and energy supply;

•

U.S. and worldwide economic conditions;

•

tax, trade and tariff policies of the United States and other countries involved in global energy markets;

•

the development, exploitation and market acceptance of alternative energy sources as part of a transition to a lower-carbon economy;

•

the proximity, capacity, cost and availability of refineries and gathering and transportation facilities;

•

the volatility and uncertainty of regional pricing differentials;

•

governmental regulations and taxation;

•

energy conservation and environmental measures; and

•

acts of force majeure.

Crude oil prices have been volatile during the last several years, and in 2025 ranged from a high of $80.04 to a low of $55.27. The NYMEX crude oil prices per Bbl were $71.65, $71.72 and $57.42 as of December 31, 2023, 2024 and 2025, respectively. Neither MV Partners nor the Trust can predict the timing or the duration of any economic cycle and, depending on the prices realized, the operating results of MV Partners and the financial condition of the Trust could be materially and adversely affected.

The terms of the Conveyance prohibit MV Partners from entering into hedging arrangements for the benefit of the Trust. As a result, the amounts of cash distributions by the Trust may fluctuate significantly

TABLE OF CONTENTS

as a result of changes in commodity prices because there will be no hedge contracts in place to reduce the effects of any changes in commodity prices.

Low prices of oil, natural gas and natural gas liquids will reduce the amount of the net proceeds to which the Trust is entitled and may ultimately reduce the amount of oil, natural gas and natural gas liquids that is economic to produce from the underlying properties. As a result, the operator of any of the underlying properties could determine during periods of low commodity prices to shut in or curtail production from wells on the underlying properties, or to plug and abandon marginal wells that otherwise may have been allowed to continue to produce for a longer period under conditions of higher prices.

Because the underlying properties are mature, with many of them being in production since the early 1900s, decreases in commodity prices could have a more significant effect on the economic viability of these properties compared to more recently discovered properties. The commodity price sensitivity of these mature wells is due to a culmination of factors that vary from well-to-well, including the additional costs associated with water handling and disposal, chemicals, surface equipment maintenance, downhole casing repairs and reservoir pressure maintenance activities that are necessary to maintain production. As a result, the volatility of commodity prices may cause the amount of future cash distributions to Trust unitholders to fluctuate, and a substantial decline in the price of oil, natural gas or natural gas liquids will reduce the amount of cash available for distribution to the Trust unitholders.

Sustained lower prices of oil and natural gas also could negatively affect the price of the Trust Units and the qualification of the Trust Units to remain listed on the New York Stock Exchange.

Actual reserves and future production may be less than current estimates of proved reserves, which could reduce cash distributions by the Trust and the value of the Trust Units.

The value of the Trust Units and the amount of future cash distributions to the Trust unitholders will depend upon, among other things, the accuracy of the production and reserves estimated to be attributable to the underlying properties and the net profits interest. Estimating production and reserves is inherently uncertain. Ultimately, actual production, revenues and expenditures for the underlying properties could vary both positively and negatively from estimates and those variations could be material. Petroleum engineers consider many factors and make assumptions in estimating production and reserves. Those factors and assumptions include:

•

historical production from the area compared with production rates from other producing areas;

•

the assumed effect of governmental regulation; and

•

assumptions about future prices of oil, natural gas and natural gas liquids, production and development expenses, gathering and transportation costs, severance and excise taxes and capital expenditures.

Changes in these assumptions could materially decrease production and reserve estimates.

The estimated reserves attributable to the net profits interest and the estimated future net revenues attributable to the net profits interest are based on estimates of reserve quantities and revenues for the underlying properties. See “Item 1. Business — Description of the Underlying Properties — Reserves” for a discussion of the method of allocating proved reserves to the underlying properties and the net profits interest. The quantities of reserves attributable to the underlying properties and the net profits interest may decrease in the future as a result of future decreases in the prices of oil, natural gas or natural gas liquids.

Risks associated with the production, gathering, transportation and sale of oil, natural gas and natural gas liquids could adversely affect cash distributions by the Trust.

The net proceeds payable to the Trust, the value of the Trust Units and the amount of cash distributions to the Trust unitholders depend upon, among other things, the costs incurred by MV Partners to develop and exploit oil and natural gas reserves attributable to the underlying properties. Drilling, production, or transportation accidents that temporarily or permanently halt the production and sale of oil, natural gas, and natural gas liquids at any of the underlying properties will reduce Trust distributions by reducing the amount of net proceeds available for distribution. For example, accidents may occur that result in personal

TABLE OF CONTENTS

injuries, property damage, damage to productive formations or equipment and environmental damages. Any costs incurred by MV Partners in connection with any such accidents that are not insured against will have the effect of reducing the net proceeds payable to the Trust and available for distribution to Trust unitholders.

In addition, curtailments or damage to pipelines used by MV Partners to transport oil, natural gas and natural gas liquid production to markets for sale could reduce the amount of net proceeds available for distribution. Any such curtailment or damage to the gathering systems used by MV Partners could also require MV Partners to find alternative means to transport the oil, natural gas and natural gas liquid production from the underlying properties, which alternative means could require MV Partners to incur additional costs that will have the effect of reducing net proceeds available for distribution by the Trust. The Trust does not maintain any type of insurance against any of the risks of conducting oil and gas exploration and production activities.

The ability or willingness of OPEC and other oil exporting nations to set and maintain production levels has a significant impact on oil and natural gas commodity prices, which could reduce the amount of cash available for distribution to Trust unitholders.

OPEC is an intergovernmental organization that seeks to manage the price and supply of oil on the global energy market. Actions taken by OPEC members, including those taken alongside other oil exporting nations, such as Russia, have a significant impact on global oil supply and pricing. For example, OPEC and certain other oil exporting nations have previously agreed to take measures, including production cuts, to support crude oil prices. OPEC members and other oil exporting nations might not agree to future production cuts or other actions to support and stabilize oil prices, and they may not reduce oil prices or increase production in the future. Uncertainty regarding future actions that OPEC members or other oil exporting countries may take could lead to continued volatility in the price of oil, which could adversely affect the financial condition and economic performance of the operators of the underlying properties and may reduce the net proceeds to which the Trust is entitled, which could materially reduce or completely eliminate the amount of cash available for distribution to Trust unitholders.

Production of oil, natural gas and natural gas liquids on the underlying properties could be materially and adversely affected by severe or unseasonable weather.

Production of oil, natural gas and natural gas liquids on the underlying properties could be materially and adversely affected by severe weather. Repercussions of severe weather conditions may include:

•

evacuation of personnel and curtailment of operations;

•

weather-related damage to drilling rigs or other facilities, resulting in suspension of operations;

•

inability to deliver materials to worksites; and

•

weather-related damage to pipelines and other transportation facilities.

Interruptions in production could have a material adverse effect on the Trust’s financial condition, results of operations and cash flows, and could reduce the amount of cash distributions to Trust unitholders for an unknown period of time.

Shortages or increases in costs of oil field equipment, services and qualified personnel available to MV Partners could reduce the amount of cash available for distribution to Trust unitholders.

The demand for qualified and experienced field personnel to drill wells and conduct field operations, geologists, geophysicists, engineers and other professionals in the oil and natural gas industry can fluctuate significantly, often in correlation with oil and natural gas prices, causing periodic shortages. Historically, there have been shortages of drilling rigs and other oilfield equipment as demand for rigs and equipment has increased along with the number of wells being drilled. These factors also cause significant increases in costs for equipment, services and personnel. Higher oil and natural gas prices generally stimulate demand and result in increased prices for drilling rigs, crews and associated supplies, equipment, and services. Shortages of field personnel and equipment or price increases could significantly decrease the amount of cash available

TABLE OF CONTENTS

for distribution to the Trust unitholders or restrict the ability of MV Partners to drill the wells and conduct the operations which it currently has planned for the underlying properties.

Financial Risks

The reserves attributable to the underlying properties are depleting assets and production from those reserves will diminish over time. Furthermore, the Trust is precluded from acquiring other oil and natural gas properties or net profits interests to replace the depleting assets and production.

The net proceeds payable to the Trust from the net profits interest are derived from the sale of oil, natural gas and natural gas liquids produced from the underlying properties. The reserves attributable to the underlying properties are depleting assets, which means that those reserves will decline over time. As a result, the quantity of oil and natural gas produced from the underlying properties is expected to decline over time. Based on the estimated production volumes in the reserve report, the oil and natural gas production from proved reserves attributable to the underlying properties is projected to decline at an average annual rate of approximately 14.55% over the next 20 years assuming no additional developmental drilling or other capital expenditures are made after 2026 on the underlying properties. The anticipated rate of decline is an estimate and actual decline rates may vary from those estimated. Pursuant to the terms of the Conveyance, the net profits interest will terminate on the Termination Date, which is June 30, 2026, since 14.4 MMBoe have been produced from the underlying properties and sold (which amount is the equivalent of 11.5 MMBoe in respect of the Trust’s right to receive 80% of the net proceeds from the underlying properties pursuant to the net profits interest). The Trust will not be entitled to any net proceeds that MV Partners receives after the Termination Date from the sale of production from the underlying properties. The net profits interest will terminate on the Termination Date, at which point the Trust will dissolve and commence winding up its business and affairs. Once the Trust winds up and terminates, it will pay no further distributions to Trust unitholders.

Future maintenance projects on the underlying properties beyond those which are currently estimated may affect the quantity of proved reserves that can be economically produced from the underlying properties. The timing and size of these projects will depend on, among other factors, the market prices of oil, natural gas, and natural gas liquids. In addition, because MV Partners has agreed to limit the amount of capital expenditures that may be taken into account in calculating net proceeds attributable to the net profits interest during a specified period preceding the termination of the net profits interest, MV Partners may choose to delay certain capital projects that may otherwise benefit the Trust unitholders until the termination of the net profits interest. If operators of the wells to which the underlying properties relate do not implement required maintenance projects when warranted, the future rate of production decline of proved reserves may be higher than the rate currently expected by MV Partners or estimated in the reserve report.

The Trust Agreement provides that the Trust’s business activities are limited to owning the net profits interest and any activity reasonably related to such ownership, including activities required or permitted by the terms of the Conveyance related to the net profits interest. As a result, the Trust is not permitted to acquire other oil and natural gas properties or net profits interests to replace the depleting assets and production attributable to the net profits interest.

Because the net proceeds payable to the Trust are derived from the sale of depleting assets, the portion of the distributions to Trust unitholders attributable to depletion may be considered to have the effect of a return of capital as opposed to a return on investment. Eventually, the underlying properties burdened by the net profits interest may cease to produce in commercially paying quantities and the Trust may, therefore, cease to receive any distributions of net proceeds therefrom.

The amount of cash available for distribution by the Trust will be reduced by the amount of any production and development costs, taxes, capital expenditures and post-production costs.

Production and development costs on the underlying properties are deducted in the calculation of the net proceeds payable to the Trust. In addition, production and property taxes, capital expenditures or post- production costs are deducted in the calculation of the net proceeds payable to the Trust. Accordingly, higher production and development expenses, taxes, capital expenditures and post-production costs will directly decrease the amount of cash received by the Trust in respect of its net profits interest. For a summary of these

TABLE OF CONTENTS

costs for the last three years, see “Item 1. Business — Description of the Underlying Properties — Producing Acreage and Well Counts.” Historical costs may not be indicative of future costs. In addition, cash available for distribution by the Trust will be further reduced by the Trust’s general and administrative expenses.

If development and production costs of the underlying properties exceed the proceeds of production from the underlying properties, the Trust will not receive net proceeds from those properties until future proceeds from production exceed the total of the excess costs plus accrued interest during the deficit period. Development activities may not generate sufficient additional revenue to repay the costs.

The Trust has established a cash reserve for contingent liabilities and to pay expenses in accordance with the Trust Agreement, which would reduce net profits payable to the Trust and distributions to Trust unitholders.

The Trust’s source of capital is the cash flows from the net profits interest. Pursuant to the Trust Agreement, the Trust may establish a cash reserve through the withholding of cash for contingent liabilities and to pay expenses, which will reduce the amount of cash otherwise available for distribution to Trust unitholders.

From the first quarter of 2022 to the second quarter of 2023, the Trustee withheld a portion of the proceeds otherwise available for distribution each quarter and built a $1.265 million cash reserve for the payment of future known, anticipated or contingent expenses or liabilities of the Trust. The Trustee may increase or decrease the targeted amount at any time and may increase or decrease the rate at which it withholds funds to build the cash reserve at any time, without advance notice to the unitholders.

A purchaser’s failure to pay MV Partners for purchased production could have a significant adverse impact on MV Partners, which in turn could result in MV Partners not having sufficient net proceeds attributable to the net profits interest for MV Partners to distribute cash to the Trust.

A purchaser’s failure to pay for purchased production could have a significant adverse impact on MV Partners’ business, which in turn could adversely affect the Trust. A tightening of credit in the financial markets may make it more difficult for purchasers to obtain financing, and depending on the degree to which this occurs, there may be a material increase in the nonpayment and nonperformance by such purchasers, which may reduce the net proceeds payable to the Trust and the amount of cash available for distribution to Trust unitholders.

If the financial position of MV Partners degrades in the future, MV Partners may not be able to satisfy its obligations to the Trust.

MV Partners is a privately held limited liability company engaged in the exploration, development, production, gathering and aggregation and sale of oil and natural gas, primarily in the Mid-Continent region in the United States, and it is responsible for operating substantially all of the underlying properties. The operating agreement of MV Partners provides that Vess Oil and Murfin Drilling will operate the underlying properties on behalf of MV Partners for which MV Partners is designated as the operator. The Conveyance provides that MV Partners is obligated to market, or cause to be marketed, the production related to the underlying properties.

The ability of MV Partners to perform its obligations related to the operation of the underlying properties will depend on MV Partners’ future financial condition and economic performance, which in turn will depend upon the supply and demand for oil and natural gas, prevailing economic conditions, collections of payments due from third parties, and upon financial, business, and other factors, many of which are beyond the control of MV Partners. If MV Partners were to be unable to perform its obligations to the Trust, it could have a material adverse effect on the net proceeds payable to the Trust and the amount of cash available for distribution to Trust unitholders.

Risks Related to the Structure of the Trust

The Trust and the public Trust unitholders have no voting or managerial rights with respect to MV Partners, the operator of the underlying properties. As a result, public Trust unitholders have no ability to influence the operation of the underlying properties.

Oil and natural gas properties are typically managed pursuant to an operating agreement among the working interest owners of oil and natural gas properties. The typical operating agreement contains

TABLE OF CONTENTS

procedures whereby the owners of the working interests in the property designate one of the interest owners to be the operator of the property. Under these arrangements, the operator is typically responsible for making all decisions relating to drilling activities, sale of production, compliance with regulatory requirements and other matters that affect the property.

MV Partners is currently designated as the operator of substantially all of the underlying properties. MV Partners has contracted with two of its affiliates, Vess Oil and Murfin Drilling, to operate these properties on its behalf. Neither the Trustee nor the public Trust unitholders has any contractual ability to influence or control the field operations of, sale of oil and natural gas from, or future development of, these properties. The public Trust unitholders also have no voting rights with respect to MV Partners and, therefore, have no managerial, contractual, or other ability to influence MV Partners’ or its affiliates’ activities as operator of the oil and natural gas properties to which substantially all of the underlying properties relate.

MV Partners may transfer all or a portion of the underlying properties at any time, subject to specified limitations, and MV Partners may abandon individual wells or properties that it reasonably believes to be uneconomic. Under these circumstances, Trust unitholders have no ability to prevent MV Partners from transferring the underlying properties to another operator, even if the Trust unitholders do not believe that operator would operate the underlying properties in the same manner as MV Partners.

MV Partners may at any time transfer all or part of the underlying properties. Trust unitholders are not entitled to vote on any transfer of the underlying properties, and the Trust will not receive any proceeds from any such transfer, except in the limited circumstances when the net profits interest is released in connection with such transfer, in which case the Trust will receive an amount equal to the fair market value of the net profits interest released. See “Item 1. Business — Description of the Underlying Properties — Sale and Abandonment of Underlying Properties.” Following any material sale or transfer of any of the underlying properties, such underlying properties will continue to be subject to the net profits interest of the Trust, and the net proceeds attributable to the transferred property will be calculated as part of the computation of net proceeds described in this Form 10-K. MV Partners may delegate to the transferee responsibility for all of MV Partners’ obligations relating to the net profits interest on the portion of the underlying properties transferred.

In addition, MV Partners may, without the consent of the Trust unitholders, require the Trust to release the net profits interest associated with any lease that accounts for no more than 0.25% of the total production from the underlying properties in the prior 12 months and provided that the net profits interest covered by such releases cannot exceed, during any 12-month period, an aggregate fair market value to the Trust of $500,000. These releases will be made only in connection with a sale by MV Partners to a non-affiliate of the relevant underlying properties and are conditioned upon the Trust’s receiving an amount equal to the fair market value to the Trust of such net profits interest. Any net sales proceeds paid to the Trust will be distributable to Trust unitholders for the quarter in which they are received.

MV Partners or any transferee of the underlying properties may abandon any well or property if it reasonably believes that the well or property can no longer produce oil or natural gas in commercially economic quantities. This could result in termination of the net profits interest relating to the abandoned well or property. In making such decisions, MV Partners and any such transferee will be required under the applicable conveyance to act as a reasonably prudent operator in the State of Kansas under the same or similar circumstances would act if it were acting with respect to its own properties, disregarding the existence of the net profits interest as a burden on such property.

The Trustee may, under certain circumstances, sell the net profits interest and dissolve the Trust prior to the expected termination of the Trust. As a result, Trust unitholders may not recover their investment.

The Trustee must sell the net profits interest if the holders of a majority of the Trust Units approve the sale or vote to dissolve the Trust. The sale of the net profits interest will result in the dissolution of the Trust. The net proceeds of any such sale will be distributed to the Trust unitholders; however, Trust unitholders may not recover their investment in the Trust Units.

The Trust will dissolve and commence winding up its business and affairs upon the Termination Date, which is June 30, 2026, the date on which the net profits interest will terminate. After the Termination Date,

TABLE OF CONTENTS

the Trustee will make a final quarterly cash distribution, if any, to the Trust unitholders of record on the 15th day following June 30, 2026. Other than such potential payment, the Trust unitholders will not be entitled to receive any net proceeds from the sale of production from the underlying properties following the Termination Date. Therefore, the market price of the Trust Units will approach and eventually reach zero shortly after the end of the net profits interest term because cash distributions from the Trust will cease following the termination of the net profits interest, and the Trust will have no right to any additional production from the underlying properties after the term of the net profits interest.

Conflicts of interest could arise between MV Partners and the Trust unitholders.

As a working interest owner in the underlying properties, MV Partners could have interests that conflict with the interests of the Trust and the Trust unitholders. For example:

•

MV Partners’ interests may conflict with those of the Trust and the Trust unitholders in situations involving the development, maintenance, operation or abandonment of the underlying properties. MV Partners may make decisions with respect to development expenditures that adversely affect the underlying properties. These decisions include reducing development expenditures on these properties, which could cause oil and natural gas production to decline at a faster rate and thereby result in lower cash distributions by the Trust in the future, or increasing development expenditures on the underlying properties during the final years of the term of the Trust, which expenditures will benefit the Trust unitholders only to the extent that they reduce the natural decline in oil and natural gas production during the term of the Trust by an amount that more than offsets the cost of these development expenditures.

•

MV Partners may sell some or all of the underlying properties and such sale may not be in the best interests of the Trust unitholders. If MV Partners sells all or any portion of the underlying properties, the purchaser of such underlying properties will acquire such underlying properties subject to the net profits interest relating thereto and, in connection therewith, such purchaser will be subject to the same standards of conduct with respect to development, operation and abandonment of such underlying properties as are currently imposed on MV Partners. MV Partners also has the right, subject to significant limitations as described herein, to cause the Trust to release all or a portion of the net profits interest in connection with a sale of a portion of the underlying properties to which such net profits interest relates. In such an event, the Trust is entitled to receive its proportionate share of the proceeds from the sale attributable to the net profits interest released. See “Item 1. Business — Description of the Underlying Properties — Sale and Abandonment of Underlying Properties.”

In addition, affiliates of MV Partners may engage in activities whereby such affiliates could have interests that conflict with the interests of MV Partners, which could, depending on the circumstances, negatively impact MV Partners’ business.

In making decisions with respect to the development, operation, abandonment or sale of the underlying properties, MV Partners and any successor operator will be required under the applicable conveyance to act as a reasonably prudent operator in the State of Kansas under the same or similar circumstances would act if it were acting with respect to its own properties, disregarding the existence of the net profits interest. Except for specified matters that require approval of the Trust unitholders, the documents governing the Trust do not provide a mechanism for resolving these conflicting interests.

The Trust is managed by a Trustee who cannot be replaced except by a majority vote of Trust unitholders holding a majority of the Trust Units at a special meeting, which may make it difficult for Trust unitholders to remove or replace the Trustee.

The business and affairs of the Trust are managed by the Trustee. The voting rights of a Trust unitholder are more limited than those of stockholders of most public corporations. For example, there is no requirement for annual meetings of Trust unitholders or for an annual or other periodic re-election of the Trustee. The Trust agreement provides that the Trustee may only be removed and replaced by the holders of a majority of the outstanding Trust Units at a special meeting of Trust unitholders called by either the Trustee or the holders of not less than 10% of the outstanding Trust Units. MV Energy and VAP-I, LLC (“VAP-I”)

TABLE OF CONTENTS

collectively own 25% of the outstanding Trust Units. As a result, it will be difficult to remove or replace the Trustee, particularly without the approval of the members of MV Partners.

Financial information of the Trust is not prepared in accordance with GAAP.

The financial statements of the Trust are 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, or GAAP. Although this basis of accounting is permitted for royalty trusts by the SEC, the financial statements of the Trust differ from GAAP financial statements because revenues are not accrued in the month of production and cash reserves may be established for specified contingencies and deducted which could not be accrued in GAAP financial statements.

The Trust is a smaller reporting company and benefits from certain reduced governance and disclosure requirements, including that the Trust’s independent registered public accounting firm is not required to attest to the effectiveness of the Trust’s internal control over financial reporting. The Trust cannot be certain if the omission of reduced disclosure requirements applicable to smaller reporting companies will make the Trust Units less attractive to investors.

Currently, the Trust is a “smaller reporting company,” meaning that the outstanding Trust Units held by nonaffiliates had a value of less than $250 million at the end of the Trust’s most recently completed second fiscal quarter. As a smaller reporting company, the Trust is not required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, meaning the Trust’s auditors are not required to attest to the effectiveness of the Trust’s internal control over financial reporting. As a result, investors and others may be less comfortable with the effectiveness of the Trust’s internal controls and the risk that material weaknesses or other deficiencies in internal controls go undetected may increase. In addition, as a smaller reporting company, the Trust takes advantage of its ability to provide certain other less comprehensive disclosures in its SEC filings, including, among other things, providing only two years of audited financial statements in annual reports. Consequently, it may be more challenging for investors to analyze the Trust’s results of operations and financial prospects, as the information the Trust provides to Trust unitholders may be different from what one might receive from other public companies in which one holds shares. As a smaller reporting company, the Trust is not required to provide this information.

Trust unitholders have limited ability to enforce provisions of the net profits interest.

The Trust Agreement permits the Trustee to sue MV Partners or any other future owner of the underlying properties on behalf of the Trust to enforce the terms of the Conveyance creating the net profits interest. If the Trustee does not take appropriate action to enforce provisions of the Conveyance, recourse of the Trust unitholders would be limited to bringing a lawsuit against the Trustee to compel the Trustee to take specified actions. The Trust Agreement expressly limits the Trust unitholders’ ability to directly sue MV Partners or any other third party other than the Trustee. As a result, the unitholders will not be able to sue MV Partners or any future owner of the underlying properties to enforce these rights. Furthermore, the Conveyance provides that, except as set forth in the Conveyance, MV Partners will not be liable to the Trust for the manner in which it performs its duties in operating the underlying properties as long as it acts without gross negligence or willful misconduct.

Risks Related to Ownership of the Trust Units

The market price for the Trust Units may not reflect the value of the net profits interest held by the Trust and, in addition, over time will decline to zero around or shortly after the termination date of the net profits interest, June 30, 2026.

The trading price for publicly traded securities similar to the Trust Units tends to be tied to recent and expected levels of cash distributions. The amounts available for distribution by the Trust will vary in response to numerous factors outside the control of the Trust, including prevailing sales prices of oil, natural gas and natural gas liquids production attributable to the underlying properties. Further, the market price of Trust Units may be affected by factors other than the anticipated future Trust distributions. Consequently, the market price for the Trust Units may not necessarily be indicative of the value that the Trust would realize if

TABLE OF CONTENTS

it sold the net profits interest to a third-party buyer. In addition, such market price may not necessarily reflect the fact that since the assets of the Trust are depleting assets, a portion of each cash distribution paid, if any, on the Trust Units should be considered by investors as a return of capital, with the remainder, if any, being considered as a return on investment. As a result, distributions made to a Trust unitholder over the life of these depleting assets may not equal or exceed the purchase price paid by the unitholder, and over time the market price of the Trust Units will decline to zero around or shortly after the Termination Date, which is June 30, 2026, the date on which the net profits interest will terminate. The Trustee will make a final quarterly cash distribution, if any, on or about July 24, 2026 to the Trust unitholders of record on the 15th day following June 30, 2026, and the Trust Units are expected to be cancelled shortly thereafter. If the Trust Units are trading at a price substantially in excess of the aggregate distributions that may reasonably be expected to be made prior to the termination of the Trust, the price decline is likely to include one or more abrupt substantial decreases.

If the Trust cannot meet the New York Stock Exchange continued listing requirements, the NYSE may delist the Trust Units.

Under the continued listing requirements of the NYSE, a company will be considered to be out of compliance with the exchange’s minimum price requirement if the company’s average closing price over a consecutive 30 trading day period is less than $1.00 (the “Minimum Price Requirement”). Under NYSE rules, a company that is out of compliance with the Minimum Price Requirement has a cure period of six months to regain compliance if it notifies the NYSE within 10 business days of receiving a deficiency notice of its intention to cure the deficiency. Due to the nature of the Trust and the limited powers of the Trustee, however, if the Trust Units were to fall below the Minimum Price Requirement, the Trust does not expect to be able to demonstrate an intention to cure any such deficiency. In that event, the NYSE has indicated that it would initiate the delisting process for the Trust Units promptly after delivering a deficiency notice to the Trust, without any cure period.

If delisted by the NYSE, the Trust Units are expected to be transferred to the over-the-counter (“OTC”) market, a significantly more limited market than the NYSE, which could affect the market price, trading volume, liquidity and resale price of the Trust Units. Securities that trade on the OTC markets also typically experience more volatility compared to securities that trade on a national securities exchange.

Due to the expected decline in the trading price of the Trust Units prior to the net profits interest termination date of June 30, 2026, the Trust may be unable to maintain compliance with the Minimum Price Requirement and could become subject to the NYSE delisting procedures prior to the termination date.

The disposal by the two members of MV Partners of their remaining Trust Units may reduce the market price of the Trust Units.

As of the date of this Form 10-K, the two members of MV Partners, MV Energy and VAP-I, owned 25% of the outstanding Trust Units. The two members of MV Partners may use some or all of the remaining Trust Units they own for a number of corporate purposes, including:

•

selling them for cash; and

•

exchanging them for interests in oil and natural gas properties or securities of oil and natural gas companies.

If they sell additional Trust Units or exchange Trust Units in connection with acquisitions, then additional Trust Units will be available for sale in the market. The sale of additional Trust Units may reduce the market price of the Trust Units. MV Partners and the Trust have entered into a registration rights agreement pursuant to which the Trust has agreed to file a registration statement or a shelf registration statement to register the resale of the remaining Trust Units held by MV Partners and any transferee of the Trust Units upon request by such holders. See “Item 13. Certain Relationships and Related Transactions, and Director Independence — Registration Rights.”

The market price for the Trust Units may not reflect the value of the net profits interest held by the Trust.

The market price for publicly traded securities similar to the Trust Units tends to be tied to recent and expected levels of cash distributions. The amounts available for distribution by the Trust will vary in

TABLE OF CONTENTS

response to numerous factors outside the control of the Trust, including prevailing prices for sales of oil, natural gas and natural gas liquid production from the underlying properties. Consequently, the market price for the Trust Units may not necessarily be indicative of the value that the Trust would realize if it sold the net profits interest to a third-party buyer. In addition, such market price may not necessarily reflect the fact that since the assets of the Trust are depleting assets, a portion of each cash distribution paid on the Trust Units should be considered by investors as a return of capital, with the remainder being considered as a return on investment. As a result, distributions made to a Trust unitholder over the life of these depleting assets may not equal or exceed the purchase price paid by the Trust unitholder.

Courts outside of Delaware may not recognize the limited liability of the Trust unitholders provided under Delaware law.

Under the Delaware Statutory Trust Act, Trust unitholders are entitled to the same limitation of personal liability extended to stockholders of private corporations under the General Corporation Law of the State of Delaware. Courts in jurisdictions outside of Delaware, however, may not give effect to such limitation.

Legal, Environmental and Regulatory Risks

The Trust’s net profits interest may be characterized as an executory contract in bankruptcy, which could be rejected in bankruptcy, thus relieving MV Partners from its obligations to make payments to the Trust with respect to the net profits interest.

MV Partners has recorded the Conveyance in Kansas in the real property records in each Kansas county where the properties are located. MV Partners has informed the Trustee that MV Partners believes that the delivery and recording of the Conveyance constitute fully conveyed and vested property interests in the Trust under Kansas law. If in a bankruptcy proceeding in which MV Partners becomes involved as a debtor a determination were made that the Conveyance constitutes an executory contract and the net profits interest is not a fully conveyed property interest under the laws of Kansas, and if such contract were not to be assumed in a bankruptcy proceeding involving MV Partners, the Trust would be treated as an unsecured creditor of MV Partners with respect to such net profits interest in the pending bankruptcy proceeding.

Oil and gas leases are real property interests under Colorado law. The net profits interest is a non-operating, non-possessory interest carved out of the oil and gas leasehold estate. MV Partners has informed the Trustee that MV Partners believes that it is possible that the net profits interest for the underlying properties located in Colorado may not be treated as a real property interest under the laws of Colorado. MV Partners has recorded the Conveyance in the real property records of Colorado in accordance with local recording acts. MV Partners has informed the Trustee that MV Partners believes that, if, during the term of the Trust, MV Partners becomes involved as a debtor in a bankruptcy proceeding, the net profits interest relating to the underlying properties located in Colorado should be treated as a fully conveyed personal property interest under the laws of Colorado. In such a proceeding, however, a determination could be made that the Conveyance constitutes an executory contract and the net profits interest is not a fully conveyed personal property interest under the laws of Colorado, and if such contract were not to be assumed in a bankruptcy proceeding involving MV Partners, the Trust would be treated as an unsecured creditor of MV Partners with respect to such net profits interest in the pending bankruptcy proceeding.

The operations of the underlying properties are subject to environmental laws and regulations and operational safety matters that may result in significant costs and liabilities, which could reduce the amount of cash available for distribution to Trust unitholders.

Significant costs and liabilities can be incurred as a result of environmental and safety requirements applicable to the oil and natural gas exploration, development and production activities of the underlying properties. These costs and liabilities could arise under a wide range of federal, state and local environmental and safety laws and regulations, including regulations and enforcement policies, which have tended to become increasingly strict over time. Failure to comply with these laws and regulations may result in the assessment of administrative, civil and criminal penalties, imposition of cleanup and site restoration costs

TABLE OF CONTENTS

and liens, and to a lesser extent, issuance of injunctions to limit or cease operations. In addition, claims for damages to persons or property may result from environmental and other impacts of the operations of the underlying properties.

Strict, joint and several liability may be imposed under certain environmental laws, which could cause liability for the conduct of others or for the consequences of one’s own actions that were in compliance with all applicable laws at the time those actions were taken. New laws, regulations or enforcement policies could be more stringent and impose unforeseen liabilities or significantly increase compliance costs. If it were not possible to recover the resulting costs through insurance or increased revenues, this could have a material adverse effect on the cash distributions to the Trust unitholders. Please read “Item 1. Business — Description of the Underlying Properties — Regulation — Environmental Matters and Regulation” for more information.

Governmental authorities may enact climate change regulations that could increase MV Partners’ costs to operate and, therefore, adversely affect distributions to the Trust unitholders.

From time to time, the U.S. Congress has considered legislation directed at reducing greenhouse gas emissions. The EPA has proposed rules to regulate greenhouse gases and regional initiatives have formed to control greenhouse gases. Additionally, the states in which MV Partners operates may implement air pollution control regulations that are more stringent than existing and proposed federal regulations, in particular the regulation of emissions of greenhouse gases. The adoption of laws and regulations to implement controls of greenhouse gases, including the imposition of fees or taxes, could adversely affect MV Partners’ operations and, therefore, distributions to the Trust unitholders.

Regulation of greenhouse gases and climate change could adversely affect Trust distributions.

The Trump Administration’s efforts to roll back federal regulation of greenhouse gases (“GHGs”) represent a significant shift in federal climate policy, though the ultimate impact of those efforts on MV Partners is unclear. In 2009, the EPA found that emissions of carbon dioxide, methane and other GHGs may present an endangerment to public health and the environment and subsequently issued regulations to restrict emissions of greenhouse gases under existing provisions of the CAA. These regulations include limits on tailpipe emissions from motor vehicles, preconstruction and operating permit requirements for certain large stationary sources, and methane emissions standards for certain new, modified and reconstructed oil and gas sources — as well as the EPA’s methane emissions guidelines for existing oil and gas sources that were adopted in 2024. The EPA also has adopted rules requiring the reporting of GHG emissions from specified large greenhouse gas emission sources in the United States, as well as certain onshore oil and natural gas production facilities, on an annual basis. Shortly after President Trump took office in January 2025, the federal government embarked on a series of changes relating to climate policy and regulation. On January 20, 2025, President Trump announced the withdrawal of the United States from the Paris Climate Agreement. In July 2025, the EPA issued a proposed rule to rescind the 2009 GHG endangerment finding that provided a basis for GHG regulation under the CAA. In September 2025, the EPA proposed to rescind the GHG reporting program for sectors other than the oil and gas sector, while proposing to suspend GHG reporting requirements for the oil and gas sector until 2034. In February 2026, the EPA adopted a final rule repealing its prior endangerment finding, which opens the door for the EPA to repeal its GHG rules for the oil and gas sector.

The EPA has established methane standards for oil and gas sources under the CAA based on the now-repealed GHG endangerment finding. In 2024, the EPA adopted a final rule that will directly regulate volatile organic compound and methane emissions from new oil and gas sources and will require further emissions reductions through its regulation of flaring, compressors, pumps, storage vessels, process controllers, well completions and liquids unloading, and equipment leaks. At the same time, the EPA adopted emissions guidelines that will apply to existing oil and gas sources and that require reductions in volatile organic compound and methane emissions that are largely equivalent to the requirements for new sources. The existing source emissions guidelines are to be implemented through state plans, with expected compliance dates for existing sources arriving in 2029. In 2025, however, the EPA extended certain compliance deadlines for both new and existing sources, and the 2026 endangerment finding repeal provides a basis for undoing the oil and gas methane standards, though the fact that the oil and gas standards address both methane and

TABLE OF CONTENTS

volatile organic compounds, which are regulated independently of EPA’s authority to regulate GHGs, may limit the impact of future changes to the methane standards that currently apply to oil and gas sources.

The Inflation Reduction Act of 2022 (“IRA”) included new CAA section 136(c) directing the EPA to collect the Waste Emissions Charge (“WEC”) from facilities in the oil and gas sector that report more than 25,000 tons of carbon dioxide equivalent emissions in a calendar year. The charge will first apply to methane emissions from calendar year 2024. The charge is determined by comparing actual reported methane emissions to statutorily established “methane intensity figures” that are based on gas production or throughput, with a charge assessed for every ton of methane emissions that exceeds the facility’s allowable emissions based on the applicable methane intensity figure. The charge will be $900 per ton for 2024 emissions and will increase to $1,200 and then $1,500 per ton in subsequent years. The program includes key exemptions, most notably a regulatory compliance exemption that applies to and exempts the emissions from facilities that are subject to and in complete compliance with the EPA’s new or existing source methane requirements. The EPA adopted new rules to implement the WEC program in November 2024; however, the fate of the WEC and the EPA rules implementing the WEC is unclear. In March 2025, President Trump signed legislation repealing the EPA’s 2024 WEC rules under the Congressional Review Act. The repeal of the EPA’s WEC rules did not eliminate the statutory requirement to pay the WEC, but it eliminated the rules established by the EPA to determine the WEC due, the payment mechanism, and any payment deadlines. The U.S. Congress may be considering amendment or repeal of certain portions of the IRA, including the statutory provisions establishing the WEC.

Meanwhile, more than one-third of the states have begun taking actions to control and/or reduce emissions of GHGs, primarily through the planned development of GHG emission inventories and/or regional GHG cap and trade programs. Although most of the state-level initiatives have to date focused on large sources of GHG emissions, such as coal-fired electric plants, it is possible that smaller sources of emissions could become subject to GHG emission limitations or allowance purchase requirements in the future. For example, the states of Colorado and New Mexico have adopted rules regulating GHGs from the oil and gas industry that are based on the federal standards. In addition, Congress may consider adopting legislation to reduce emissions of greenhouse gases. Any one of these climate change regulatory and legislative initiatives could have a material adverse effect on MV Partners’ business, capital expenditures, financial condition and results of operations.

The adoption and implementation of regulations imposing reporting obligations on, or limiting emissions of GHGs from, MV Partners’ equipment and operations could require MV Partners to incur costs to reduce emissions of GHGs associated with its operations or could adversely affect demand for the natural gas it produces. Legislation or regulations that may be adopted to address climate change could also affect the markets for MV Partners’ products by making its products less desirable than competing sources of energy. To the extent that its products are competing with lower GHG-emitting energy, MV Partners’ products may become less desirable in the market with more stringent limitations on greenhouse gas emissions. MV Partners cannot predict with any certainty at this time how these possibilities may affect its operations.

In addition, future regulatory initiatives in the U.S. related to climate change disclosure or reporting could adversely affect the Trust. In 2024, the SEC issued a final rule regarding the enhancement and standardization of mandatory climate-related disclosures for investors. The final rule mandates extensive disclosure of climate-related data, risks, and opportunities, including financial impacts, physical and transition risks, related governance and strategy and greenhouse gas emissions, for certain public companies. The SEC’s climate disclosure rule was challenged in court, and in March 2025 the SEC announced that it had voted to end its defense of the 2024 rule. The outcome of that litigation or separate rule changes made by the SEC may result in changes to climate-related disclosure requirements. Even in the absence of federal requirements, however, some states have adopted climate disclosure laws or rules that are not affected by the SEC’s review. Compliance with the federal or state disclosure rules may result in increased legal, accounting and financial compliance costs, make some activities more difficult, time-consuming and costly, and place strain on the personnel, systems and resources of MV Partners or the Trust or both.

occur, they could have an adverse effect on MV Partners’ assets and operations and cause MV Partners to incur costs in preparing for and responding to them. Additionally, energy needs could increase or decrease as a result of extreme weather conditions, depending on the duration and magnitude of those conditions.

The operations of the underlying properties are subject to complex federal, state, local and other laws and regulations that could adversely affect the cash distributions to the Trust unitholders.

The exploration, development and production operations of the underlying properties are subject to complex and stringent laws and regulations. In order to conduct its operations in compliance with these laws and regulations, MV Partners must obtain and maintain numerous permits, approvals and certificates from various federal, state and local governmental authorities. MV Partners may incur substantial costs and experience delays in order to maintain compliance with these existing laws and regulations, and the net profits interest will bear its share of these costs. In addition, the costs of compliance may increase or the operations of the underlying properties may be otherwise adversely affected if existing laws and regulations are revised or reinterpreted, or if new laws and regulations become applicable to such operations. Such costs could have a material adverse effect on the cash distributions to the Trust unitholders.

Laws and regulations governing exploration and production may also affect production levels. MV Partners is required to comply with federal and state laws and regulations governing conservation matters, including: provisions related to the unitization or pooling of oil and natural gas properties; the establishment of maximum rates of production from wells; the spacing of wells; the plugging and abandonment of wells; and the removal of related production equipment. These and other laws and regulations can limit the amount of oil and natural gas MV Partners can produce from its wells, limit the number of wells it can drill, or limit the locations at which it can conduct drilling operations, which in turn could negatively impact Trust distributions, estimated and actual future net revenues to the Trust and estimates of reserves attributable to the Trust’s interests.

New laws or regulations, or changes to existing laws or regulations, may unfavorably impact MV Partners, could result in increased operating costs or have a material adverse effect on MV Partners’ financial condition and results of operations and reduce the amount of cash received by the Trust. For example, Congress is currently considering legislation that, if adopted in its proposed form, would subject companies involved in oil and natural gas exploration and production activities to, among other items, additional regulation of and restrictions on hydraulic fracturing of wells, the elimination of certain U.S. federal tax incentives and deductions available to oil and natural gas exploration and production activities, and the prohibition or additional regulation of private energy commodity derivative and hedging activities. These and other potential regulations could increase the operating costs of the underlying properties, reduce MV Partners’ liquidity, delay MV Partners’ operations or otherwise alter the way MV Partners conducts its business, any of which could have a material adverse effect on the net profits interest and the Trust’s cash flows.

Tax Risks Related to the Trust Units

The Trust has not requested a ruling from the IRS regarding the tax treatment of ownership of the Trust Units or the tax treatment of the net profits interest. If the IRS were to determine (and be sustained in that determination) that the Trust is not a grantor Trust for federal income tax purposes, or that the net profits interest is not a debt instrument for federal income tax purposes, the Trust unitholders may receive different and less advantageous tax treatment than that described in this Form 10-K.

Tax counsel to MV Partners advised the Trust at the time of formation that, for federal income tax purposes, in its opinion MV Partners will be treated as a grantor Trust and not as an unincorporated business entity. Tax counsel to MV Partners also advised the Trust at the time of formation that, for federal income tax purposes, based upon representations made by MV Partners regarding the expected economic life of the underlying properties and the expected duration of the net profits interest, in its opinion the net profits interest should be treated as a “production payment” under Section 636 of the Code or otherwise as a debt instrument.

TABLE OF CONTENTS

If the net profits interest were not treated as a debt instrument, or if the Trust were not treated as a grantor Trust, for federal income tax purposes, the tax treatment of tax items in respect of an investment in Trust Units may be affected. The effects of this different tax treatment may be less advantageous to Trust unitholders.

Neither MV Partners nor the Trustee has requested a ruling from the IRS regarding these tax questions. Such a ruling may not be granted if requested; moreover, the IRS could challenge these positions on audit. See “Item 1. Business — Federal Income Tax Matters” for more information about the various matters described under this risk factor.

Cybersecurity Risks

Cyber-attacks or other failures in telecommunications or information technology systems could result in information theft, data corruption and significant disruption of MV Partners’ business operations.

MV Partners relies on information technology (“IT”) systems and networks in connection with its business activities, including exploration, development and production activities. MV Partners relies on digital technology, including information systems and related infrastructure, as well as cloud applications and services, to, among other things, estimate quantities of oil and natural gas reserves, analyze seismic and drilling information, process and record financial and operating data and communicate with employees and third parties. As dependence on digital technologies has increased, cyber incidents, including deliberate attacks and attempts to gain unauthorized access to computer systems and networks, have increased in frequency and sophistication. These threats pose a risk to the security of MV Partners’ systems and networks, the confidentiality, availability and integrity of its data and the physical security of its employees and assets. This risk is exacerbated with the advancement of technologies like artificial intelligence, which malicious third parties are using to create new, sophisticated and more frequent attacks. Furthermore, geopolitical tensions or conflicts, such as the ongoing wars in Ukraine and in the Persian Gulf, may further heighten the risk of cybersecurity attacks.

MV Partners has experienced, and expects to continue to experience, attempts from hackers and other third parties to gain unauthorized access to its IT systems and networks. Although prior cyber-attacks have not had a material adverse effect on MV Partners’ operations or financial performance, MV Partners may not be successful in preventing cyber-attacks or mitigating their effect. Any cyber-attack could have a material adverse effect on MV Partners’ reputation, competitive position, business, financial condition and results of operations, and could have a material adverse effect on the Trust. Cyber-attacks or security breaches also could result in litigation or regulatory action, as well as significant additional expense to MV Partners to implement further data protection measures.

In addition to the risks presented to MV Partners’ systems and networks, cyber-attacks affecting oil and natural gas distribution systems maintained by third parties, or the networks and infrastructure on which they rely, could delay or prevent delivery to markets. A cyber-attack of this nature would be outside MV Partners’ ability to control but could have a material adverse effect on MV Partners’ business, financial condition and results of operations, and could have a material adverse effect on the Trust.

Cyber-attacks or other failures in telecommunications or IT systems could result in information theft, data corruption and significant disruption of the Trustee’s operations.

The Trustee depends heavily upon IT systems and networks in connection with its business activities. Despite a variety of security measures implemented by the Trustee, events such as the loss or theft of back-up tapes or other data storage media could occur, and the Trustee’s computer systems could be subject to physical and electronic break-ins, cyber-attacks and similar disruptions from unauthorized tampering, including threats that may come from external factors, such as governments, organized crime, hackers and third parties to whom certain functions are outsourced, or may originate internally from within the respective companies.

If a cyber-attack were to occur, it could potentially jeopardize the confidential, proprietary and other information processed and stored in, and transmitted through, the Trustee’s computer systems and networks, or otherwise cause interruptions or malfunctions in the operations of the Trust, which could result in

TABLE OF CONTENTS

litigation, increased costs and regulatory penalties. Although steps are taken to prevent and detect such attacks, it is possible that a cyber incident will not be discovered for some time after it occurs, which could increase exposure to these consequences.

Item 1B. Unresolved Staff Comments.

None.

Item 1C. Cybersecurity.

The Trust has no directors or executive officers. The affairs of the Trust are managed by the Trustee. The Trust falls under the cybersecurity program of The Bank of New York Mellon Corporation (“BNY Mellon”), the parent corporation of The Bank of New York Mellon Trust Company, N.A. As further described in its 2025 Annual Report, BNY Mellon maintains a broad range of defenses aimed at remaining abreast of and responding to evolving cybersecurity threats impacting it, its operations, its clients, its third-party service providers and the broader financial services sector.

Risk Management Strategy and Procedures

BNY Mellon has implemented policies and procedures designed to detect, prevent and respond to malicious and accidental disruptions to the delivery of critical technology services. BNY Mellon’s cybersecurity risk management program is embedded in its three lines of defense model.

As part of its first line of defense, BNY Mellon maintains a dedicated Cybersecurity organization, led by the Chief Information Security Officer (the “CISO”), that is responsible for the day-to-day management of risks from cybersecurity threats. Cybersecurity’s responsibilities include cybersecurity threat intelligence, incident response and other cybersecurity operations aimed at enabling BNY Mellon to identify, assess and manage existing and emerging cybersecurity threats. Cybersecurity monitors for potential threats and communicates relevant risks to the CISO and other members of executive management. Additionally, Cybersecurity maintains a cybersecurity incident response and reporting process pursuant to which cybersecurity incidents are classified according to their severity based upon an assessment of multiple factors. Certain cybersecurity incidents may activate enterprise-wide resiliency processes, which include, among other things, escalation through the management and Board committee structures described below. In addition, BNY Mellon maintains a preparedness program designed to reinforce cybersecurity risk management practices and compliance with BNY Mellon’s policies and procedures. The preparedness program includes mandatory training for all employees, contractors and consultants, enhanced training for those in roles presenting higher risk, calibrated phishing email simulations, distribution of information security awareness materials and cybersecurity event simulation exercises. In addition, BNY Mellon leverages both internal and external assessments and engages with third-party assessors, consultants and auditors to evaluate and test its cybersecurity controls and provide guidance on potential improvements, including design and operating effectiveness. BNY Mellon’s information security management system is certified to the ISO 27001 standard by an independent, accredited certification body, and BNY Mellon maintains this certification through periodic external audits and ongoing monitoring.

BNY Mellon has a defined third-party governance framework to help manage the risk posed to it by the use of third-party service providers. BNY Mellon evaluates the risk posed by third-party service engagements based on multiple factors. BNY Mellon has protocols that seek to mitigate cybersecurity risks associated with third-party service providers based on the risk level assigned to such third party, which may include mandatory contractual obligations or the implementation of additional controls by BNY Mellon and/or the applicable service provider.

Cybersecurity is subject to ongoing review and challenge from Technology Risk Management, which is a part of the independent second line of defense risk function. Technology Risk Management, together with the broader Risk & Compliance group, is responsible for and manages BNY Mellon’s risk management framework and establishes guidance for Cybersecurity and management designed to help identify, assess and manage cybersecurity risk.

BNY Mellon’s Internal Audit function serves as the third line of defense and provides an independent view on how effectively the organization as a whole manages cybersecurity risk.

TABLE OF CONTENTS

Risk Management Oversight and Governance

BNY Mellon’s management is responsible for assessing and managing BNY Mellon’s material risks from cybersecurity threats with oversight provided by its Board of Directors (the “Board”) and the Board committees. The Risk Committee of the Board has primary responsibility for oversight of the overall operation of BNY Mellon’s risk management framework, including policies and practices addressing cybersecurity risk, and is responsible for the oversight of the second line of defense with respect to its cybersecurity risk management responsibilities. The Technology Committee of the Board and the full Board regularly receive reports and briefings from management concerning cybersecurity matters, including any significant changes to BNY Mellon’s cybersecurity program. BNY Mellon also has protocols for escalating cybersecurity threats and incidents to the Technology Committee of the Board and the full Board. In addition, the Audit Committee of the Board monitors and oversees the performance of Internal Audit, including with respect to its cybersecurity risk management responsibilities.

At the management level, BNY Mellon’s Technology Oversight Committee, which is the senior management committee responsible for the governance and oversight of BNY Mellon’s significant technology projects and initiatives, reviews reports from management concerning Cybersecurity and is responsible for, among other things, escalating issues, including significant cybersecurity threats and incidents, to the Technology Committee of the Board and the full Board of Directors. The Technology Oversight Committee is chaired by the Chief Information Officer and Global Head of Engineering (the “CIO”).

BNY Mellon’s Technology Risk Committee is the most senior governance committee primarily focused on cybersecurity and technology risk issues and is a part of the second line of defense risk function. It is responsible for, among other things, overseeing and reviewing emerging cybersecurity risks, significant cybersecurity incidents and remediation plans. The Technology Risk Committee receives reports from management and has protocols for escalating certain issues and risks to the Enterprise Risk Committee and the Risk Committee of the Board. The Technology Risk Committee is chaired by the Chief Technology Risk Officer. Members include key leaders from the first line of defense, including the CISO.

Market for Registrant’s Common Equity, Related Unitholder Matters and Issuer Purchases of Equity Securities.

The Trust Units commenced trading on the New York Stock Exchange on January 19, 2007 under the symbol “MVO.” As of March 20, 2026, the 11,500,000 Trust Units outstanding were held by 10 Trust unitholders of record.

Distributions

Each quarter, the Trustee determines the amount of funds available for distribution to the Trust unitholders. Available funds are the excess cash, if any, received by the Trust from the net profits interest and other sources (such as interest earned on any amounts reserved by the Trustee) that quarter, less the Trust’s expenses for that quarter. Available funds are reduced by any cash that the Trustee decides to hold as a reserve against future expenses. Quarterly cash distributions during the term of the Trust are made by the Trustee on or before the 25th day of the month following the end of each quarter to the Trust unitholders of record on the 15th day of the month following the end of each quarter (or the next succeeding business day).

Item 7.

Trustee’s Discussion and Analysis of Financial Condition and Results of Operations.

The following review of the Trust’s financial condition and results of operations should be read in conjunction with the financial statements and notes thereto. The Trust’s purpose is, in general, to hold the net profits interest, to distribute to the Trust unitholders cash that the Trust receives in respect of the net profits interest, and to perform certain administrative functions in respect of the net profits interest and the Trust Units. The Trust derives substantially all of its income and cash flows from the net profits interest.

Critical Accounting Policies and Estimates

The Trust uses the modified cash basis of accounting to report receipts by the Trust of the net profits interest and payments of expenses incurred. The net profits interest represents the right to receive revenues (oil, gas and natural liquid gas sales) less direct operating expenses (lease operating, maintenance and overhead expenses and production and property taxes) and an adjustment for lease equipment cost and lease development expenses (which are capitalized in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”)) of the underlying properties times 80%. Cash distributions of the Trust will be made based on the amount of cash received by the Trust pursuant to terms of the Conveyance.

The financial statements of the Trust, as prepared on a modified cash basis, reflect the Trust’s assets, Trust corpus, earnings and distributions as follows:

(a)

Income from the net profits interest is recorded when distributions are received by the Trust;

(b)

Distributions to Trust unitholders are recorded when paid by the Trust;

(c)

Trust general and administrative expenses (which include the Trustee’s fees as well as accounting, engineering, legal and other professional fees) are recorded when paid;

TABLE OF CONTENTS

(d)

Cash reserves for Trust expenses may be established by the Trustee for certain expenditures that would not be recorded as contingent liabilities under U.S. GAAP;

(e)

Amortization of the investment in net profits interest, calculated using the units-of-production method based upon total estimated proved reserves, is charged directly to Trust corpus and does not affect distributable income; and

(f)

The Trust evaluates its investment in the net profits interest periodically to determine whether its aggregate value has been impaired below its total capitalized cost based on the underlying properties. The Trust will provide a write-down to its investment in the net profits interest if and when total capitalized costs, less accumulated amortization, exceed undiscounted future net cash flows attributable to the Trust’s interests in the proved oil and gas reserves of the underlying properties.

While these statements differ from financial statements prepared in accordance with U.S. GAAP, the modified cash basis of reporting revenues and distributions is considered most meaningful because quarterly distributions to the Trust unitholders are based on net cash receipts received from MV Partners. This comprehensive basis of accounting other than U.S. GAAP corresponds to the accounting permitted for royalty Trusts by the SEC as specified by Staff Accounting Bulletin Topic 12:E, Financial Statements of Royalty Trusts.

Termination of the Trust

As of December 31, 2025, cumulatively, since inception, the Trust has received payment for 80% of the net proceeds attributable to MV Partners’ interest from the sale of 14.7 MMBoe of production from the underlying properties (which amount is the equivalent of 11.8 MMBoe with respect to the Trust’s net profits interest). Consequently, pursuant to the terms of the Conveyance, the net profits interest will terminate on June 30, 2026 (the “Termination Date”), because the minimum amount of production (14.4 MMBoe) applicable to the net profits interest has been produced and sold (which amount is the equivalent of 11.5 MMBoe with respect to the Trust’s net profits interest). The Trustee will make a final quarterly cash distribution, if any, on or about July 24, 2026 to the Trust unitholders of record on the 15th day following June 30, 2026, and the Trust Units are expected to be cancelled shortly thereafter. The Trust will not be entitled to any net proceeds that MV Partners receives after the Termination Date from the sale of production from the underlying properties. The Trust will dissolve and commence winding up its business and affairs after the Termination Date, and once the Trust winds up and terminates, it will pay no further distributions.

Comparison of Results of the Trust for the Years Ended December 31, 2025 and 2024

The following represents a discussion of the Comparison of Results of the Trust for the Years Ended December 31, 2025 and 2024. Refer to “Item 7. Trustee’s Discussion and Analysis of Financial Condition and Results of Operations” in the Trust’s Annual Report on Form 10-K for the year ended December 31, 2024, filed with the SEC on March 20, 2025, for a discussion of the Comparison of Results of the Trust for the Years Ended December 31, 2024 and 2023.

Income for the Trust from the net profits interest was $11.3 million for the year ended December 31, 2025 compared to $18.6 million for the year ended December 31, 2024. The Trustee withheld $0.9 million and $0.9 million for future Trust expenses for the years ended December 31, 2025 and 2024, respectively. General and administrative expense for the Trust was $1.0 million for 2025 and $0.9 million for 2024. These factors resulted in distributable income of $10.4 million, or $0.905 per Trust Unit, in 2025 compared to $17.7 million, or $1.535 per Trust Unit, in 2024.

The revenues from oil production are typically received by MV Partners one month after production; thus, the cash received by the Trust during the year ended December 31, 2025 substantially represented the production by MV Partners from September 2024 through August 2025, and the cash received by the Trust during the year ended December 31, 2024 substantially represented the production by MV Partners from September 2023 through August 2024. MV Partners computes net proceeds quarterly on a calendar basis and distributes to the Trust 80% of the aggregate of such net proceeds attributable to a computation period on or before the 25th day of the month following the computation period. As a result, for the year ended December 31, 2025, the Trust’s net profits interest represented the cash proceeds received by the Trust,

which was based upon the cash receipts for the oil and gas production collected by MV Partners from October 1, 2024 through September 30, 2025. For the year ended December 31, 2024, the Trust’s net profits interest represented the cash proceeds received by the Trust, which was based upon the cash receipts for the oil and gas production collected by MV Partners from October 1, 2023 through September 30, 2024.

Excess of revenues over direct operating expenses and lease equipment and development costs from the underlying properties was $14.1 million for the period from October 1, 2024 through September 30, 2025. The Trust’s net profits interest (80%) of this total was $11.3 million for the year ended December 31, 2025. During the year ended December 31, 2025, MV Par
