Forward-Looking Statements

Certain information included in this Quarterly Report on Form 10-Q contains, or incorporates by reference, not only historical information, but also “forward-looking statements” within the meaning of Section 21E of the Securities Exchange Act of 1934. All such forward-looking statements, including those statements regarding estimation of iron ore pellet production, shipments, pricing, royalties and other matters, are based on information from the lessee/operator (and its parent corporation) of the mine located on the lands owned and held in trust for the benefit of the holders of units of beneficial interest of Mesabi Trust (“Mesabi Trust” or the “Trust”). These statements may be identified by the use of forward-looking words, such as “may,” “will,” “could,” “project,” “predict,” “intend,” “believe,” “anticipate,” “expect,” “estimate,” “continue,” “potential,” “plan,” “should,” “assume,” “forecast” and other similar words. Such forward-looking statements are inherently subject to known and unknown risks and uncertainties. Actual results and future developments could differ materially from the results or developments expressed in or implied by these forward-looking statements. These risks and uncertainties include, but are not limited to, volatility of iron ore and steel prices, market supply and demand, competition, environmental hazards, health and safety conditions, regulation or government action, litigation, uncertainties about estimates of reserves, general adverse business and industry economic trends, uncertainties arising from war, terrorist events and other global events, higher or lower customer demand for steel and iron ore, decisions by mine operators regarding curtailments or idling production lines or entire plants, environmental compliance uncertainties, difficulties in obtaining and renewing necessary operating permits, higher imports of steel and iron ore substitutes, processing difficulties, consolidation and restructuring in the domestic steel market, market inputs tied to indexed price adjustment factors found in some Cliffs’ customer contracts resulting in future adjustments to royalties payable to Mesabi Trust, and other factors. Further, substantial portions of royalties earned by Mesabi Trust are based on estimated prices that are subject to interim and final adjustments, which can be positive or negative, and are dependent in part on multiple price and inflation index factors under agreements to which Mesabi Trust is not a party and that are not known until after the end of a contract year. It is possible that future negative price adjustments could partially or even completely offset royalties or royalty income that would otherwise be payable to the Trust in any particular quarter, or at year-end, thereby potentially reducing cash available for distribution to the Trust’s Unitholders (as defined below) in future quarters.

For a discussion of the factors, including without limitation, those that could materially and adversely affect Mesabi Trust’s actual results and performance, see “Risk Factors” set forth on pages 4 through 1918 of Mesabi Trust’s Annual Report for the fiscal year ended January 31, ~~2025~~2026, as updated by the “Risk Factors” on page 18 of this quarterly report. These risks and uncertainties are not exclusive and further information concerning the Trust, including factors that potentially could materially affect our operating results, financial condition or the market price of the Units, may emerge from time to time. Mesabi Trust undertakes no obligation, other than that imposed by law, to make any revisions to the forward-looking statements contained in this filing or to update them to reflect circumstances occurring after the date of this filing. We advise you, however, to consult any further disclosures we make on related subjects in our future Quarterly Reports on Form 10-Q, Annual Reports on Form 10-K and Current Reports on Form 8-K that we file with or furnish to the Securities and Exchange Commission.

Mesabi Trust

Notes to Condensed Financial Statements

~~October~~April 3130, ~~2025~~2026 (Unaudited)

Note 1. The condensed financial statements and notes to the condensed financial statements of Mesabi Trust (the “Trust”) included herein have been prepared in accordance with the instructions to Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to such rules and regulations. In the opinion of the Trustees of Mesabi Trust (the “Trustees”), all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of (a) the results of operations for the three ~~and nine~~ months ended ~~October~~April 3130, ~~2025~~2026 and ~~2024~~2025, (b) the financial position as of ~~October~~April 3130, ~~2025~~2026 and (c) the cash flows for the ~~nine~~three months ended ~~October~~April 3130, ~~2025~~2026 and ~~2024~~2025, have been made. For further information, refer to the financial statements and footnotes included in Mesabi Trust’s Annual Report on Form 10-K for the year ended January 31, ~~2025~~2026.

Note 2. Net income per unit is based on 13,120,010 units outstanding during all periods presented.

The Trust accounts for revenue in accordance with ASC 606 - Revenue from Contracts with Customers. All revenue is recognized as the performance obligations are satisfied. Mesabi Trust holds all of the interests formerly owned by Mesabi Iron Company (“MIC”), including all right, title and interest in the Amendment of Assignment, Assumption and Further Assignment of Peters Lease dated August 17, 1989 among the trustees of Mesabi Trust, Bruce D. Sherling, as Trustee in Bankruptcy for the Estate of Reserve Mining Company, and Cypress Northshore Mining Corporation, predecessor to Northshore Mining Company (referred to as the “Amended Assignment of Peters Lease” or the “Royalty Agreement”). In accordance with the Royalty Agreement, the Trust recognizes revenue for providing access to the lands and minerals only after the consideration that it is entitled to receive is determinable. The Trust is entitled to payment upon production of pellets to be sold for internal use by facilities owned by Cleveland -Cliffs Inc. (“Cliffs”), the parent company of Northshore Mining Company (“Northshore” or “NMC”), or its subsidiaries. As a result, the Trust recognizes revenue for internal use pellets upon production of those pellets, which are deemed to be shipped under the Royalty Agreement, regardless of pellet grade. Pellets that are not designated for internal use by Cliffs, or its subsidiaries, are recognized as revenue upon shipment from Silver Bay, Minnesota. Shipped product and deemed shipped product are hereafter collectively referred to as “shipped.”

Disaggregation of Revenues

The following table represents a disaggregation of royalty revenue for the three ~~and nine~~ months ended ~~October~~April 3130, ~~2025~~2026 and ~~October~~April 3130, ~~2024~~2025.

Fee royalties		547,650		457,396
Total royalty income	$	13,156,985	$	19,613,693

Base overriding royalties

The performance obligation for the base overriding royalty consists of providing NMC access to the Peters Lands, Cloquet Lands, and Mesabi Lands and the right to mine on these lands. The consideration to be received from this access under the Amended Assignment of Peters Lease relates to the volume of iron ore shipped. The Trust receives royalties at the greater of (i) the aggregate quantity of iron ore products shipped, that were mined from Mesabi Trust Lands, and (ii) a portion of the aggregate quantity of all iron ore products shipped, that were mined from any lands during the calendar year, such portion being 90% of the first four million tons shipped during such year, 85% of the next two million tons shipped, during such year, and 25% of all tonnage shipped in excess of six million tons during such year.

Table of Contents

The royalty percentage paid to the Trust increases as the aggregate tonnage of iron ore products shipped, attributable to the Trust in any calendar year increases. The Trust earns a 2.5% royalty on the first million tons shipped in a calendar year, 3.5% on the second million tons, 5.0% on the third million tons, 5.5% on the fourth million tons and 6.0% beyond four million tons. The base overriding royalties contain variable consideration, as the transaction price is based on a percentage that varies based on the total cumulative tons of iron ore shipped. Under the Royalty Agreement, measurement of the total cumulative volumes of iron ore shipped and the applicable royalty percentages are reset at the beginning of each calendar year. The Trust estimates the variable consideration it expects to be entitled to receive based on the estimated average royalty percentage over the calendar year periods that are included in the Trust’s fiscal year. The Trust evaluates the estimate of the variable consideration to determine whether the estimate needs to be constrained and includes the variable consideration in the transaction price only to the extent that it is probable that a significant reversal of the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. The Trust estimates the base overriding royalty percentage using the expected value method, which calculates the estimate based on historical, current, and forecasted shipments. At each quarter end, the Trust updates its estimate of total tons expected to be shipped for the calendar year and applies the estimated annual royalty rate to actual tons shipped in the quarter. The Trust recognizes revenue for base overriding royalties on a quarterly basis based on actual shipments, the estimated annual royalty rate and estimated prices for iron ore products sold under Cliffs’ customer contracts.

Bonus royalties

The performance obligation for the bonus royalties consists of providing NMC access to the Peters Lands, Cloquet Lands, and Mesabi Lands and the right to mine on these lands. The consideration to be received from this access under the Amended Assignment of Peters Lease relates to the volume of iron ore shipped, by NMC. The Trust recognizes bonus royalties on a quarterly basis based on shipments for the fiscal quarter at the actual royalty percentage for those shipments and based on the anticipated prices for iron ore products sold under Cliffs’ customer contracts. The Trust is paid royalty bonuses when iron ore products shipped are sold at anticipated prices above a threshold price per ton. The royalty bonus is based on a percentage of the gross proceeds of product shipped. The royalty bonus percentage ranges from 1/2 of 1% of the gross proceeds (on all tonnage shipped for sale at prices between the threshold price and $2.00 above the threshold price) to 3% of the gross proceeds (on all tonnage shipped for sale at prices $10.00 or more above the threshold price). The threshold price is adjusted annually for inflation and is $6971.4170 per ton for calendar year ~~2025~~2026 and was $6769.7541 per ton for calendar year ~~2024~~2025.

AAA Arbitration 2024 Final Award

As previously reported, on October 14, 2022, Mesabi Trust initiated arbitration against Northshore, the lessee/operator of the leased lands, and its parent, Cliffs, with the American Arbitration Association (“AAA”). The Trust sought an award of damages relating to Cliffs’ and Northshore’s underpayment of royalties in 2020, 2021, and the first four months of 2022 by virtue of Cliffs’ and Northshore’s failure to use the highest priced arms’-length iron ore pellet sale from the preceding four quarters in pricing certain pellet shipments from 2020 through the first four months of 2022. The Trust also sought declaratory relief related to the Trust’s entitlement to certain documentation and to the time when Cliffs’ and Northshore’s royalty obligations accrue.

The evidentiary hearing was completed before a panel of three arbitrators in March 2024 under the commercial rules of the AAA. Post-hearing briefs were exchanged in May 2024. Post-hearing oral arguments and final submissions were concluded in June 2024. The Trust received the final award on September 6, 2024, which unanimously awarded the Trust damages in the amount of $59,799,977 for underpaid royalties in 2020, 2021 and the first four months of 2022, plus pre-award interest in the amount of $11,385,052, calculated at the rate of 10% simple interest per annum from the date of the initial demand through the date of the award. Pursuant to the award, Cliffs and Northshore were required to pay the Trust the amounts specified in the Award by no later than October 6, 2024. The Tribunal approved the parties’ stipulated Consent Award approving the Trust’s ongoing entitlement to certain documentation related to verifying royalty calculations. The Tribunal denied the Trust’s request for declaratory relief regarding the time at which Cliffs’ and Northshore’s royalty obligations accrue.

Pursuant to the AAA tribunal’s unanimous final award dated September 6, 2024, Northshore and Cliffs paid Mesabi Trust $71,185,029 on October 4, 2024 as a final award, including interest. This non-recurring revenue was reflected as “Arbitration Award” under “Revenues” on the Trust’s Condensed Statement of Income for the quarter ended October 31, 2024.

Fee royalties

Fee royalties are determined based on the volume of crude ore mined on a quarterly basis. The Trust recognizes fee royalties on a quarterly basis based on the actual crude ore mined during the fiscal quarter. Fee royalties are payable to the Mesabi Land Trust, a Minnesota land trust, which holds a 20% interest as fee owner in the Amended Assignment of Peters Lease. The Trust holds the entire beneficial interest in the Mesabi Land Trust for which U.S. Bank N.A. acts as the corporate trustee. The Trust receives the net income of the Mesabi Land Trust, which is generated from royalties on the amount of crude ore mined after the payment of expenses to U.S. Bank N.A. for its services as the corporate trustee. The fee royalty on crude ore is based on an agreed price per ton, subject to certain indexing.

mined after the payment of expenses to U.S. Bank N.A. for its services as the corporate trustee. The fee royalty on crude ore is based on an agreed price per ton, subject to certain indexing.

Accrued income receivable

Accrued income receivable represents royalty income earned but not yet received by the Trust. Accrued income receivable is comprised of (i) shipments during the last month of the Trust’s fiscal quarter, if any, and (ii) net positive price adjustments, if any, (which may include the sum of positive and negative price adjustments) resulting from price adjustment mechanisms in the agreements between Cliffs and its customers that determine the final sales price of the shipments from Silver Bay, Minnesota.

Contract asset and contract liability

The contract asset and contract liability are presented net in the accompanying balance sheets as both the contract asset and contract liability are derived from one customer contract. A net contract asset in the amount of $1867,~~055,605~~363 is reflected on the Balance Sheet as of ~~October~~April 3130, ~~2025~~2026. The net contract asset is made up of a contract asset in the amount of $1867,~~055,605~~363 and no contract liability. As of January 31, ~~2025~~2026, the Trust recorded a net contract asset in the amount of $~~240~~263,~~642~~982, made up of a contract asset of $~~240~~263,~~642~~982 and no contract liability. The contract asset relates to variable consideration for base overriding royalties that occurs as a result of escalating base overriding royalty rates earned as thresholds for tons of ore shipped are reached, as described in the base overriding royalties section above. The recorded contract asset represents the additional revenue earned based on the estimated annual royalty rate compared to the effective contracted rate for tons shipped during the period. The contract asset is not available for distribution to the Unitholders until the applicable royalties are actually received by the Trust.

Note 3. The Trustees determine whether to declare a distribution each year in April, July, October and January. The Trust’s financial statements are prepared on an accrual basis and present the Trust’s results of operations based on each of the Trust’s fiscal quarters, which end one month after the close of each calendar quarter. Because (i) distributions, if any, are declared by the Trustees based on, among other considerations, the amount of royalties actually paid to the Trust through the end of each calendar quarter prior to April, July, October and January of each year, the Trustees’ evaluation of known and projected Trust expenses in the current and future quarters, the then-current level of Unallocated Reserve and general economic conditions, and (ii) the Trust’s Net income is calculated as of the end of each fiscal quarter, the distributions declared by the Trust are not equivalent to the Trust’s Net income during the periods reported in this Quarterly Report on Form 10-Q.

Note 4. On October 10, 2025, the Trustees declared a distribution of $0.34 per Unit of Beneficial Interest payable on November 20, 2025 to Mesabi Trust Unitholders of record at the close of business on October 30, 2025. The declared distribution of $4,460,803 is recorded as a distribution payable on the Condensed Balance Sheet for the quarter ended October 31, 2025 (unaudited) as compared to a distribution payable of $0.39 per Unit of Beneficial Interest for the quarter ended October 31, 2024. 7

Note 4. On April 14, 2026, the Trustees declared a distribution of $0.24 per Unit of Beneficial Interest payable on May 20, 2026 to Mesabi Trust Unitholders of record at the close of business on April 30, 2026. The declared distribution of $3,148,802 is recorded as a distribution payable on the Condensed Balance Sheet for the quarter ended April 30, 2026 (unaudited) as compared to a distribution payable of $0.56 per Unit of Beneficial Interest for the quarter ended April 30, 2025.

On ~~October~~April 30, ~~2025~~2026, the Trustees received the quarterly royalty report of iron ore production and shipment during the calendar quarter ended ~~September~~March 3031, ~~2025~~2026 from Cliffs. See “Recent Developments— Receipt of Quarterly Royalty Report and Royalty Payment from Cliffs” as set forth on page 1513 of this Quarterly Report on Form 10-Q for the fiscal quarter ended ~~October~~April 3130, ~~2025~~2026.

Each quarter, as authorized by the Agreement of Trust dated July 18, 1961, as amended (the “Agreement of Trust”), the Trustees evaluate all relevant factors, including all costs, expenses, obligations, and present and future liabilities of the Trust (whether fixed or contingent) in determining a prudent level of unallocated reserve in light of the unpredictable nature of the iron ore industry, current economic conditions and current communications from Cliffs as it relates to NMC.

Pursuant to the Agreement of Trust, the Trustees make decisions about cash distributions to Unitholders based on the royalty payments it receives from Cliffs when received, rather than as royalty income is recorded in accordance with the Trust’s revenue recognition policy. Refer to Note 3 for further information.

8As of April 30, 2026 and January 31, 2026, the unallocated cash and cash equivalents portion of the Trust’s Unallocated Reserve was comprised of the following components. Cash equivalents consists of U.S. government securities with maturities of 3 months or less as of the date of acquisition by the Trust.

Item 2. Trustees’ Discussion and Analysis of Financial Condition and Results of Operations.

This discussion should be read in conjunction with the condensed financial statements and notes presented in this Quarterly Report on Form 10-Q and the financial statements and notes in the last filed Annual Report on Form 10-K for the year ended January 31, ~~2025~~2026 for a full understanding of Mesabi Trust’s financial position and results of operations for the three ~~and nine~~ months ended ~~October~~April 3130, ~~2025~~2026.

All references in this discussion and in this Quarterly Report on Form 10-Q to iron ore products “shipped” or “shipments” shall include iron ore products that are actually shipped from Silver Bay, Minnesota and/or stockpiled for intercompany use that Cleveland -Cliffs Inc. (“Cliffs”) has deemed shipped, as referenced by the parties to, and in accordance with, the Amended Assignment

of Peters Lease. Following the outcome of the 2019 arbitration, Cliffs began accruing royalty payments to the Trust for both DR pellets and standard pellets to be sold for internal use at facilities owned by Cliffs or its subsidiaries. This accrual method was upheld in the September 6, 2024 arbitration award. As a result, the Trust recognizes revenue for Cliffs’ internal use pellets upon production of those pellets, regardless of pellet grade. Pellets produced by Northshore Mining Company (“Northshore” or “NMC”) that are not designated for internal use by Cliffs, or its subsidiaries, and instead are intended for sale to third parties in arms’-length sales, continue to be recognized as revenue upon shipment from Silver Bay, Minnesota.

Background

Mesabi Trust, formed pursuant to the Agreement of Trust, is a trust organized under the laws of the State of New York. Mesabi Trust holds all of the interests formerly owned by Mesabi Iron Company (“MIC”), including all right, title and interest in the Amendment of Assignment, Assumption and Further Assignment of Peters Lease dated August 17, 1989 among the trustees of Mesabi Trust, Bruce D. Sherling, as Trustee in Bankruptcy for the Estate of Reserve Mining Company, and Cypress Northshore Mining Corporation, predecessor to Northshore (referred to as the “Amended Assignment of Peters Lease” or the “Royalty Agreement”), the Amendment of Assignment, Assumption and Further Assignment of Cloquet Lease (the “Amended Assignment of Cloquet Lease” and together with the Amended Assignment of Peters Lease, the “Amended Assignment Agreements”), the beneficial interest in a trust organized under the laws of the State of Minnesota to administer the Mesabi Fee Lands (as defined below) as the trust corpus in compliance with the laws of the State of Minnesota on July 18, 1961 (the “Mesabi Land Trust”) and all other assets and property identified in the Agreement of Trust. The Amended Assignment of Peters Lease relates to an Indenture made as of April 30, 1915 among East Mesaba Iron Company (“East Mesaba”), Dunka River Iron Company (“Dunka River”) and Claude W. Peters (the “Peters Lease”) and the Amended Assignment of Cloquet Lease relates to an Indenture made May 1, 1916 between Cloquet Lumber Company and Claude W. Peters (the “Cloquet Lease”).

The Agreement of Trust specifically prohibits the Trustees of the Mesabi Trust (the “Trustees”) from entering into or engaging in any business. This prohibition applies even to business activities the Trustees may deem necessary or proper for the preservation and protection of the Trust Estate. Accordingly, the Trustees’ activities in connection with the administration of Trust assets are limited to collecting income, paying expenses and liabilities, distributing net income to the holders of Certificates of Beneficial Interest in Mesabi Trust (“Unitholders”) after the payment of, or provision for, such expenses and liabilities, and protecting and conserving the assets held by the Trust.

The Trustees do not intend to expand their responsibilities beyond those permitted or required by the Agreement of Trust, as amended by the Amendment to the Agreement of Trust dated October 25, 1982 (the “Agreement of Trust”), and those required under applicable law. Mesabi Trust has no employees, but it engages independent consultants to assist the Trustees in, among other things, monitoring the volume and sales prices of iron ore products shipped, based on information supplied to the Trustees by Northshore, the lessee/operator of the lands leased under the Peters Lease and Cloquet Lease (the “Peters Lease Lands” and “Cloquet Lease Lands,” respectively) and the 20% fee interest of certain lands that are particularly described in, and subject to a mining lease under, the Peters Lease (the “Mesabi Fee Lands,” and together with the Peters Lease Lands and Cloquet Lease Lands, the “Mesabi Trust Lands”), and its parent company, Cliffs. References to Northshore or NMC in this quarterly report, unless the context requires otherwise, are applicable to Cliffs as well.

Leasehold royalty income constitutes the principal source of the Trust’s revenue. The income of the Trust is highly dependent upon the activities and operations of Northshore. Royalty rates and the resulting royalty payments received by the Trust are determined in accordance with the terms of the Trust’s leases and assignments of leases.

Three types of royalties, as well as royalty bonuses, comprise the Trust’s leasehold royalty income:

● Base overriding royalties. Base overriding royalties have historically constituted the majority of the Trust’s royalty income. Base overriding royalties are determined by both the volume and selling price of iron ore products shipped. Northshore is obligated to pay the Trust base overriding royalties in varying amounts, based on the volume of iron ore products shipped. Base overriding royalties are calculated as a percentage of the gross proceeds of iron ore products produced at Mesabi Trust Lands (and to a limited extent other lands) and shipped. The percentage ranges from 2-1/2% of the gross proceeds for the first one million tons of iron ore products shipped annually to 6% of the gross proceeds for all iron ore products in excess of four million tons shipped annually. Base overriding royalties ~~typically~~ are subject to interim and final price adjustments under Cliffs’ customer contracts ~~(to the extent they are utilized)~~ and, as described elsewhere in this report, such adjustments may be positive or negative.

● Royalty bonuses. The Trust earns royalty bonuses when iron ore products shipped are sold at prices above a threshold price per ton. The royalty bonus is based on a percentage of the gross proceeds of product shipped. The threshold price is adjusted (but not below $30.00 per ton) on an annual basis for inflation and deflation (the “Adjusted Threshold Price”). The Adjusted Threshold Price is $6971.4170 per ton for calendar year ~~2025~~2026 and was $6769.7541 per ton for calendar year ~~2024~~2025. The royalty bonus percentage ranges from 1/2 of 1% of the gross proceeds (on all tonnage shipped for sale at prices between the Adjusted Threshold Price and $2.00 above the Adjusted Threshold Price) to 3% of the gross proceeds (on all tonnage shipped for sale at prices $10.00 or more

109

Table of Contents

above the Adjusted Threshold Price). Royalty bonuses ~~typically~~ are subject to price adjustments under Cliffs’ customer contracts ~~(to the extent they are utilized)~~ and, as described elsewhere in this report, such adjustments may be positive or negative.

●

Fee royalties. Fee royalties have historically constituted a smaller component of the Trust’s total royalty income. Fee royalties are payable to the Mesabi Land Trust, a Minnesota land trust, which holds a 20% interest as fee owner in the Amended Assignment of Peters Lease. Mesabi Trust holds the entire beneficial interest in the Mesabi Land Trust for which U.S. Bank N.A. acts as the corporate trustee. Mesabi Trust receives the net income of the Mesabi Land Trust, which is generated from royalties on the amount of crude ore mined after the payment of expenses to U.S. Bank N.A. for its services as the corporate trustee. Crude ore is the source of iron oxides used to make iron ore pellets and other products. The fee royalty on crude ore is based on an agreed price per ton, subject to certain indexing.

● Minimum advance royalties. Northshore’s obligation to pay base overriding royalties and royalty bonuses with respect to the sale of iron ore products generally accrues upon the shipment of those products. However, regardless of whether any shipment has occurred, Northshore is obligated to pay to Mesabi Trust a minimum advance royalty. Each year, the amount of the minimum advance royalty is adjusted (but not below $500,000 per annum) for inflation or deflation. The minimum advance royalty is $1,~~157~~195,~~261~~452 for calendar year ~~2025~~2026 and was $1,~~129~~157,~~615~~261 for calendar year ~~2024~~2025. Until overriding royalties (and royalty bonuses, if any) for a particular year equal or exceed the minimum advance royalty for the year, Northshore must make quarterly payments of up to 25% of the minimum advance royalty for the year. Because minimum advance royalties are essentially prepayments of base overriding royalties and royalty bonuses earned each year, any minimum advance royalties paid in a fiscal quarter are recouped by credits against base overriding royalties and royalty bonuses earned in later fiscal quarters during the year.

The current royalty rate schedule became effective on August 17, 1989 pursuant to the Amended Assignment Agreements, which the Trust entered into with Cyprus Northshore Mining Corporation (“Cyprus NMC”). Pursuant to the Amended Assignment Agreements, overriding royalties are determined by both the volume and selling price of iron ore products shipped. In 1994, Cyprus NMC was sold by its parent corporation to Cliffs and renamed Northshore Mining Company. Cliffs now operates Northshore as a wholly owned subsidiary.

Under the relevant agreements, Northshore has the right to mine and ship iron ore products from lands other than Mesabi Trust Lands. Northshore alone determines whether to conduct mining operations on Mesabi Trust Lands and/or such other lands based on its current mining and engineering plan. The Trustees do not exert any influence over mining operational decisions. To encourage the use of iron ore products from Mesabi Trust Lands, Mesabi Trust receives royalties on stated percentages of iron ore shipped, whether or not the iron ore products are from Mesabi Trust Lands. Mesabi Trust receives royalties at the greater of (i) the aggregate quantity of iron ore products shipped that were mined from Mesabi Trust Lands, and (ii) a portion of the aggregate quantity of all iron ore products shipped that were mined from any lands, such portion being 90% of the first four million tons shipped during such year, 85% of the next two million tons shipped during such year, and 25% of all tonnage shipped during such year in excess of six million tons. The royalty percentage paid to the Trust increases as the aggregate tonnage of iron ore products shipped, attributable to the Trust, in any calendar year increases past each of the ton volume thresholds. Assuming a consistent sales price per ton throughout a calendar year, shipments of iron ore product attributable to the Trust later in the year generate a higher royalty to the Trust, as total shipments for the year exceed the one million ton thresholds.

During the course of its typical fiscal year, ~~historically~~ some portion of royalties expected to be paid to Mesabi Trust ~~would~~is be based in part on estimated prices for certain iron ore products sold under some of the Cliffs’ customer contracts. ~~Generally,~~The Cliffs’ customer contracts ~~have~~use ~~typically used~~ estimated prices which are subject to interim and final pricing adjustments, which can be positive or negative, and are dependent in part on multiple price and inflation index factors that are not known until after the end of a contract year. Even though Mesabi Trust is not a party to the Cliffs’ customer contracts, these adjustments can result in significant variations in royalties payable to Mesabi Trust (and, in turn, the resulting amount available for distribution to Unitholders by the Trust) from quarter to quarter and on a comparative historical basis, and these variations, which can be positive or negative, cannot be predicted by the Trust. In either case, ~~when used in Cliffs’ third party customer contracts,~~ these price adjustments ~~would~~will impact future royalties payable to the Trust and, in turn, ~~would~~will impact cash reserves that may become available for distribution to Unitholders.

Historically, sales volumes under most of its multi-year supply agreements with Cliffs’ customers, in general, are largely dependent on customer requirements and contain a base price that is adjusted annually using one or more adjustment factors. The factors that could result in price adjustments under Cliffs’ customer contracts include changes in the Platts 62% Price, hot-rolled coil steel price, the Atlantic Basin pellet premium, published Platts international indexed freight rates and changes in specified producer price indices, including those for industrial commodities, fuel and steel.

As also described elsewhere in this report, the Trust receives a bonus royalty equal to a percentage of the gross proceeds of iron ore products (mined from Mesabi Trust Lands) shipped and sold at prices above the Adjusted Threshold Price. Although 9895.35% of all the iron ore products shipped during calendar ~~2024~~2025 ~~was~~were sold at prices higher than the Adjusted Threshold Price, the Trustees are unable to project whether Cliffs will continue to be able to sell iron ore products at prices above the applicable Adjusted Threshold Price, entitling the Trust to any future bonus royalty payments.

As described in this report, in order to calculate the royalties owed by Northshore to Mesabi Trust, the Royalty Agreement requires that Northshore make sales of iron ore products to third parties on an arms’-length basis without regard to any other business relationship between Northshore and the third-party buyer of the iron ore products. In order to calculate royalties on less than arms’-length sales (including sales from Northshore to Cliffs’ corporate affiliates), the Royalty Agreement requires reference to the highest contract price obtained by Northshore in the preceding four calendar quarters in a sale to a buyer not affiliated with Northshore and made on an arms’-length basis. Since Cliffs’ acquisition of ArcelorMittal USA in late-2020, and accelerating after Cliffs’ Toledo HBI plant came online in mid-2021, Northshore has increased the proportion of iron ore mined from the Mesabi Trust Lands that it sells to Cliffs’ corporate affiliates and decreased the proportion of such iron ore that it sells to third parties in arms’-length transactions. Cliffs’ public statements beginning in October 2021 have indicated that Cliffs will be limiting the tonnage of iron ore pellets that it sells to third parties from all of its mines, and particularly Northshore. Cliffs’ recent royalty reports reported three sale transactions of iron ore pellets shipped to a single third-party customer in September and December 2025. As reported by Cliffs, these third-party customer pellet sale transactions were comprised of lower volumes than historically typical shipment volumes. These iron ore pellets shipped to a third party in September and December 2025 are priced below the 2026 Adjusted Threshold Price (which is used in calculating royalty bonuses payable to the Trust under the Royalty Agreement). The Trust did not record any royalty bonus revenue during the quarter ended April 30, 2026. See “Risk Factors – The limited arms’-length third-party sales of iron ore products (processed at Northshore using Mesabi Trust iron ore) by Cliffs at prices below the annual adjusted bonus royalty threshold price eliminated a bonus royalty during the Trust’s fiscal quarter ended April 30, 2026, could continue to reduce or even eliminate bonus royalties historically paid to the Trust and could result in potential disputes regarding the amount of royalties owed to the Trust” as set forth in “Part II, Item 1A. Risk Factors” on page 18 of this Report. The Trust is continuing to evaluate whether such transactions meet the requirements of the royalty agreement. Without consistent arms’-length sales of iron ore pellets from Northshore to third parties, the calculation of royalties on iron ore pellets that Northshore ships to Cliffs’ affiliates could be uncertain under the Royalty Agreement, which could in turn result in potential disputes regarding the amount of royalties owed to the Trust. Historically, Cliffs has not fully responded to the Trust’s inquiries about its planning and efforts on these matters, and Cliffs has not reported to the Trust regarding such matters.

12The table below shows that the base overriding royalties decreased $539,395 and the bonus royalties decreased by $1,783,835 for the three months ended April 30, 2026, as compared to the three months ended April 30, 2025. Fee royalties increased

Table of Contents

by $51,569 over the same period. The decrease in the base overriding royalties and bonus royalties is attributable to a decrease in prices received on pellets of iron ore which resulted in no bonus royalty revenue received during the three months ended April 30, 2026 as compared to the three months ended April 30, 2025. The increase in the fee royalties is attributable to an increase in crude ore mined during the three months ended April 30, 2026 as compared to the three months ended April 30, 2025, due to the extended maintenance shut down at Northshore during the fiscal quarter ended April 30, 2025.

As reflected in the table below, the Trust’s total royalty income for the three months ended October 31, 2025 decreased by $3,957,757 to $3,390,609 as compared to the three months ended October 31, 2024. The decrease in total royalty income is attributable to a decrease in both pricing and shipments of iron ore during the three months ended October 31, 2025 as compared to the three months ended October 31, 2024.

The decrease in the base overriding royalties is attributable to a decrease in both pricing and shipments of iron ore during the three months ended October 31, 2025 as compared to the three months ended October 31, 2024. The decrease in the bonus royalty is attributable to a decrease in the prices of products shipped over the threshold price per ton which resulted in a lower bonus royalty rate during the three months ended October 31, 2025 as compared to the three months ended October 31, 2024. The increase in the fee royalties is attributable to an increase in the royalty rate paid during the three months ended October 31, 2025 as compared to the three months ended October 31, 2024.

Net income for the three months ended April 30, 2026 was $1,087,463, a decrease of $2,543,745 as compared to the three months ended April 30, 2025. The ~~table~~decrease ~~below~~in ~~summarizes~~net income for the ~~components~~three months ended April 30, 2026 is primarily attributable to a decrease in royalty income during the quarter ended April 30, 2026 compared to the same period in the prior year. The decrease in royalty income is due to a decrease in prices received on pellets of ~~Mesabi~~iron ore which resulted in no bonus royalty revenue received during the three months ended April 30, 2026.

As reflected in the table below, the Trust’s total royalty income for the nine months ended October 31, 2025 decreased by $6,456,708 to $13,156,985 as compared to the nine months ended October 31, 2024. The decrease in royalty income is attributable to Northshore being in an extended maintenance shut down in February 2025 along with a decrease in both pricing and shipments of iron ore during the nine months ended October 31, 2025, as compared to the nine months ended October 31, 2024.

Comparison of Net Income, Expenses and Distributions for the Three and Nine Months Ended October 31, 2025 and October 31, 2024

Net income for the three months ended October 31, 2025 was $2,767,463, a decrease of $75,558,062 as compared to the three months ended October 31, 2024. The decrease in net income for the three months ended October 31, 2025 is primarily attributable to the recognition of revenue related to the AAA arbitration award in the prior period and a decrease in royalty income due to a decrease in both pricing and shipments, as well as a reduction in the bonus royalty rate of iron ore during the three months ended October 31, 2025 as compared to the three months ended October 31, 2024. The Trust’s expenses for the three months ended October 31, 2025 were $822,987, an increase of $146,672 compared to the expenses for the three months ended October 31, 2024. The increase in

Net income for the nine months ended October 31, 2025 was $11,142,554, a decrease of $76,064,649 as compared to the nine months ended October 31, 2024. The decrease in net income for the nine months ended October 31, 2025 is primarily due to the recognition of revenue related to the AAA arbitration award in the prior period and a decrease in royalty income attributed to an extended maintenance shut down in February 2025 along with a decrease in both pricing and shipments of iron ore and a decrease in the prices of products shipped over the threshold price per ton which resulted in a lower bonus royalty rate during the nine months ended October 31, 2025, as compared to the nine months ended October 31, 2024.

The decrease in expenses was primarily attributable to a decrease in legal fees for the nine months ended October 31, 2025 as compared to the prior comparable period during which the Trust was engaged in active arbitration. The table below summarizes the Trust’s income and expenses for the nine months ended October 31, 2025 and October 31, 2024, respectively.

As presented on the “Trust’s Condensed Statements of Income” on page 3 of this quarterly report, the Trust’s net income per unit decreased $5.7590 per unit to $0.2109 per unit for the fiscal quarter ended October 31, 2025, as compared to the fiscal quarter ended October 31, 2024. On October 10, 2025, the Trust declared a distribution of $0.34 per unit payable on November 20, 2025 to Unitholders of record on October 30, 2025. Comparatively, the Trust declared a distribution of $0.39 per unit during the quarter ended October 31, 2024. During the nine months ended October 31, 2025 and October 31, 2024, the Trust declared distributions totaling $1.02 per unit to Unitholders of record and $0.98, respectively.

On a quarterly basis, the Trustees review a variety of financial and economic data and information impacting the Trust, and upon the Trustees’ determination, distributions may be declared approximately eleven weeks after the Trustees receive a quarterly royalty report from Northshore and Cliffs and the Trust receives the actual royalty payment with respect to royalty income that is payable for iron ore shipments through the end of each prior calendar quarter. Royalty payments may include pricing adjustments with respect to shipments made during prior periods. The Trust accounts for and reports accrued income receivable based on shipments during the last month of each of the Trust’s fiscal quarters (April, July, October and January) and price adjustments under Cliffs’ customer contracts (which can be positive or negative and can result in significant variations in royalties received by Mesabi Trust and cash available for distribution to Unitholders) as reported to the Trust by Northshore. The Trust accounts for these amounts by using estimated prices and reports such amounts as revenue even though accrued income receivable is not available for distribution to Unitholders until it is received by the Trust. Accordingly, distributions declared by the Trust are not equivalent to the Trust’s net income during the periods reported in this Quarterly Report on Form 10-Q.

Comparison of Unallocated Reserve as of ~~October~~April 3130, ~~2025~~2026, ~~October~~April 3130, ~~2024~~2025 and January 31, ~~2025~~2026

As set forth in the table below, Unallocated Reserve decreased from $9519,~~324~~611,~~736~~719 as of ~~October~~April 3130, ~~2024~~2025 to $2118,~~087~~341,~~860~~533 as of ~~October~~April 3130, ~~2025~~2026. The decrease in Unallocated Reserve as of ~~October~~April 3130, ~~2025~~2026, as compared to ~~October~~April 3130, ~~2024~~2025, is primarily the result of a decrease in ~~unallocated cash and cash equivalents and a decrease in~~ accrued income receivable. ~~The~~caused ~~decrease~~by ina ~~the~~decrease ~~unallocated cash and cash equivalents portion of the Unallocated Reserve is~~ in ~~part~~prices ~~attributable to AAA arbitration award being~~ received ason pellets of ~~October~~iron ~~31,~~ore ~~2024,~~ which ~~was~~resulted ~~subsequently distributed to unitholders.

It is possible that future negative price adjustments could offset, or even eliminate, future royalties or royalty income that would otherwise be payable to the Trust in any particular quarter, or at year end, thereby potentially reducing cash available for distribution to the Trust’s Unitholders in future quarters. See the discussion under the heading “Risk Factors” beginning on page 4 of the Trust’s Annual Report on Form 10-K for the fiscal year ended January 31, ~~2025~~2026 (filed April 2422, ~~2025~~2026).

Each quarter, as authorized by the Agreement of Trust, the Trustees will reevaluate all relevant factors including all costs, expenses, obligations, and present and future liabilities of the Trust (whether fixed or contingent) in determining a prudent level of unallocated reserve in light of the unpredictable nature of the iron ore industry, current and projected future mining operations and current economic conditions. Although the actual amount of the Unallocated Reserve will fluctuate from time to time and may increase or decrease from its current level, it is currently anticipated that future distributions will be highly dependent upon royalty income as it is received and the level of Trust expenses. The amount of future royalty income available for distribution will be asubject ~~function~~to of the volume of iron ore ~~products~~product ~~produced~~shipments ~~or shipped~~ and the dollar ~~amount~~level ~~from~~of ~~the~~sales ~~sale to third-party customers in bona fide transactions~~ by Northshore ~~that meet the requirements of the royalty agreement~~. ~~Production~~Shipping ~~and shipping~~ activity is greatly reduced during the winter months. As previously disclosed, on April 25, 2023, Cliffs announced that “higher levels of steel production have led to the partial restart of some operations at … [its] iron ore mining and pelletizing swing facility at Northshore earlier this month.” Cliffs also announced that it “…will continue to treat that facility as our swing operation. And at this time, we still do not expect to operate Northshore in full any time this year.” The Trustees have not been provided with any additional information regarding the anticipated volume of production, stockpiling or shipping of iron ore products at the Northshore operations in Babbitt and Silver Bay, Minnesota. General adverse business and industry economic trends, uncertainties arising from war, terrorist events and other global events, higher or lower customer demand for steel and iron ore, decisions by mine operators regarding curtailments or idling production lines or entire plants, environmental compliance uncertainties, difficulties in obtaining and renewing necessary operating permits, higher imports of steel and iron ore substitutes, processing difficulties and consolidation and restructuring in the domestic steel market may adversely affect the amount and timing of such future shipments and sales. The Trustees will continue to monitor the economic and other circumstances of the Trust to strike a responsible balance between distributions to Unitholders and the need to maintain adequate reserves at a prudent level, given the unpredictable nature of the iron ore and steel industry, the Trust’s dependence on the actions of Cliffs/Northshore, and the fact that the Trust essentially has no other liquid assets.

In

As reported to Mesabi Trust by Cliffs in the Royalty Report, based on shipments of iron ore products by Northshore during the three months ended September 30, 2025, Mesabi Trust was credited with a base royalty of $2,817,500. For the three months ended September 30, 2025, Mesabi Trust was also credited with a bonus royalty in the amount of $973,410. Cliffs reported that no adjustments were made in the third quarter. In addition, a royalty payment of $214,232 was paid to the Mesabi Land Trust. Accordingly, the total royalty payments received by Mesabi Trust on October 30, 2025 from Cliffs were $4,005,142.13

The royalties paid to Mesabi Trust are based on the volume of iron ore pellets and other products produced or shipped during the quarter and the year to date, the pricing of iron ore product sales, and the percentage of iron ore pellet production and shipments from Mesabi Trust lands rather than from non-Mesabi Trust lands. In the third calendar quarter of 2025, Cliffs credited Mesabi Trust with 987,370 tons of iron ore shipped, as compared to 972,154 tons shipped or produced during third calendar quarter of 2024. Cliffs’ Royalty Report reported three sale transactions of iron ore pellets shipped to a single third-party during September 2025, which are subject to continued due diligence review. Cliffs’ Royalty Report also indicated that royalty calculations are based on prices that are subject to change.

The volume of iron ore pellets (and other iron ore products) produced or shipped by Northshore varies from quarter to quarter and year to year based on a number of factors, including, among others, Cliffs’ decisions to idle Northshore operations (which occurred from May 2022 until April 2023), the requested delivery schedules of customers (including affiliates), general economic conditions in the iron ore industry, and production schedules and weather conditions on the Great Lakes. These multiple factors can result in significant variations in royalties received by Mesabi Trust (and in turn, the resulting funds available for distribution to Unitholders by Mesabi Trust) from quarter to quarter and from year to year. These variations, which can be positive or negative, cannot be predicted by the Trustees of Mesabi Trust. Based on the above factors, and as indicated by Mesabi Trust’s historical distribution payments, the royalties received by Mesabi Trust, and the distributions paid to Unitholders, if any, in any particular quarter are not necessarily indicative of royalties that will be received, or distributions that will be paid, if any, in any subsequent quarter or full year.

Trust’s Prior Announcement of a Thirty-Four Cents Distribution

On October 10, 2025, Mesabi Trust issued a press release announcing that the Trustees of Mesabi Trust declared a distribution of thirty-four cents ($0.34) per Unit of Beneficial Interest payable on November 20, 2025 to Mesabi Trust Unitholders of record at the close of business on October 30, 2025. This compares to a thirty-nine cent ($0.39) per Unit distribution declared for the same period last year.

Cleveland-Cliffs Announcement of Replacing Aluminum with Steel in Automotive Stamping Equipment

On October 29, 2025, Cliffs announced that it successfully completed a production trial in collaboration with a major automotive OEM, in which Cliffs’ exposed steel parts were stamped with no defects using the OEM’s existing aluminum-forming equipment. Cliffs press release indicated that the trial marks a significant milestone in demonstrating that Cliffs steel can effectively replace aluminum in critical automotive applications without the need for costly retooling. Cliffs described this as a major breakthrough in the wake of recent major disruptions, presumably long-lasting, in the aluminum supply chain.

According to Cliffs’ press release, this achievement was made possible through Cliffs’ industry-leading technical service and application engineering teams, who worked directly with the OEM’s production and tooling specialists to fine-tune the material design and forming parameters. According to Cliffs, the result was a smooth transition from aluminum to steel, with no changes required to the stamping line.

Cliffs reported that all deemed shipments out of Silver Bay for the calendar quarter ended March 31, 2026 were below the 2026 adjusted bonus royalty threshold of $71.70 per ton. The prices Cliffs reported for deemed shipments in this quarter were based on a third-party sale that occurred in September 2025. Other than the time period related to Cliffs’ ~~Announcement~~temporarily idling of ~~Pricing~~Northshore ~~its~~operations ~~Underwritten~~from ~~Public~~May ~~Offering~~2022 to April 2023, this represents the first time in many years that Cliffs’ quarterly royalty report and royalty payment did not report and pay Mesabi Trust a bonus royalty for shipments of iron ore pellets made during the applicable quarter.

~~Cleveland-~~The volume of iron ore pellets (and other iron ore products) produced or shipped by Northshore varies from quarter to quarter and year to year based on a number of factors including, among others, Cliffs’ ~~Announcement~~decisions to idle Northshore operations (which occurred from May 2022 until April 2023), the requested delivery schedules of ~~POSCO~~customers (including affiliates), general economic conditions in the iron ore industry, and production schedules and weather conditions on the Great Lakes. These multiple factors can result in significant variations in royalties received by Mesabi Trust (and in turn, the resulting funds available for distribution to Unitholders by Mesabi Trust) from quarter to quarter and from year to year. These variations, which can be positive or negative, cannot be predicted by the Trustees of Mesabi Trust. Based on the above factors, and as ~~MOU~~indicated ~~Strategic~~by ~~Partner~~Mesabi Trust’s historical distribution payments, the royalties received by Mesabi Trust, and the distributions paid to Unitholders, if any, in any particular quarter are not necessarily indicative of royalties that will be received, or distributions that will be paid, if any, in any subsequent quarter or full year.

On July 29, 2025, WaterLegacy filed a motion for a temporary injunction seeking to enjoin DNR from issuing any further approvals and Northshore from engaging in any construction or development activities related to the proposed project, including any activities to extend dams, relocate railroads, increase dam heights, expand the tailings basin footprint, or increase tailings deposition, pending resolution of the litigation or completion of environmental review. On September 4, 2025, the court issued an order denying the requested temporary injunction. The case is proceeding, and trial is set to occur in September 2027.14

The Trustees are unable to predict what impact, if any, the ~~WaterLegacy~~Minnesota ~~lawsuit~~Court of Appeals’ decision to reverse and remand the DNR order or the DNR’s future redetermination regarding whether the proposed project requires an EIS will have on mining, production and shipments of iron ore products from Northshore or future royalties payable to the Trust.

On June 16, 2025, WaterLegacy filed a civil complaint in the Second Judicial District, Ramsey County, Minnesota, Case No. 62-cv-25-4810, seeking injunctive and declaratory relief against the DNR and Northshore in relation to the proposed Mile Post 7 tailings basin project. WaterLegacy seeks declaratory and injunctive relief under the Minnesota Environmental Policy Act (“MEPA”) and the Minnesota Environmental Rights Act (“MERA”). WaterLegacy specifically asks the court to (1) declare that any DNR approvals or Northshore construction activities related to the proposed project prior to completion of an EIS are prohibited under MEPA and (2) enjoin these approvals and activities until the EIS process is complete. WaterLegacy also asks the court to (1) declare that the proposed project’s dam enlargement violates or is likely to violate Minnesota dam permitting standards and rules and (2) enjoin the DNR and Northshore from proceeding with the proposed project until a new dam permit is issued in compliance with Minnesota statutes and rules. Trial was scheduled to occur in September 2027.

On March 2, 2026, the parties jointly filed a stipulation seeking a stay of the case, reporting that the parties had engaged in settlement discussions and “progressed sufficiently that a stay of [the] matter is appropriate” in order to “allow the parties to focus their attention and energy on resolving terms and finalizing what will likely be a complicated settlement agreement.” On March 3, 2026, the Court referred the case to mediation and issued an order granting a stay of the matter until the Court orders otherwise.

The Trustees are unable to predict what impact, if any, the WaterLegacy lawsuit, or any settlement thereof, will have on mining, production and shipments of iron ore products from Northshore or future royalties payable to the Trust.

Forward-Looking Statements

This report contains certain forward-looking statements based on Cliffs’ publicly announced plans with respect to Northshore in the future, which statements are intended to be made under the safe harbor protections of the Private Securities Litigation Reform Act of 1995, as amended. Cliffs’ implementation of, or changes to, these plans are beyond Mesabi Trust’s control. As such, such statements are subject to risks and uncertainties, which could cause actual results to differ materially.

Although the Mesabi Trustees believe that any such forward-looking statements are based on reasonable assumptions, such statements are subject to risks and uncertainties, which could cause actual results to differ materially. Additional information concerning these and other risks and uncertainties is contained in Mesabi Trust’s filings with the Securities and Exchange Commission, including its Annual Report on Form 10-K for the fiscal year ended January 31, ~~2025~~2026 (filed April 2422, ~~2025~~2026). Mesabi Trust undertakes no obligation to publicly update or revise any of the forward-looking statements made herein to reflect events or circumstances after the date hereof.

Important Factors Affecting Mesabi Trust

The Agreement of Trust specifically prohibits the Trustees from entering into or engaging in any business. This prohibition seemingly applies even to business activities the Trustees deem necessary or proper for the preservation and protection of the Trust’s assets. Accordingly, the Trustees’ activities in connection with the administration of Trust assets are limited to collecting income, paying expenses and liabilities, distributing net income to Mesabi Trust’s Unitholders after the payment of, or provision for, such expenses and liabilities, monitoring royalties and protecting and conserving the held assets.

Neither Mesabi Trust nor the Trustees have any control over the operations and activities of Northshore, except within the framework of the ~~Royalty~~Amended ~~Agreement~~Assignment of Peters Lease, and the framework of the Peters Lease (by virtue of Mesabi Land Trust’s interest in that Lease). Cliffs alone controls (i) historical operating data, including iron ore production volumes, decisions to reduce or idle the Northshore plant and mining operations, marketing of iron ore products, operating and capital expenditures as they relate to Northshore, environmental and other liabilities and the effects of regulatory changes; (ii) plans for Northshore’s future operating and capital expenditures; (iii) geological data relating to ore reserves; (iv) projected production of iron ore products; (v) contracts between Cliffs and Northshore with their customers; and (vi) the decision to mine off Mesabi Trust and/or state lands, based on Cliffs’ current mining and engineering plan. The Trustees do not exert any influence over mining operational decisions at Northshore, nor do the Trustees provide any input regarding the ore reserve ~~estimated~~estimates at Northshore as reported by Cliffs. While the Trustees request relevant information from Cliffs and Northshore in accordance with the Royalty Agreement for use in periodic reports as part of their evaluation of Mesabi Trust’s disclosure controls and procedures, the Trustees do not control this information and they rely on the information in Cliffs’ periodic and current filings with the SEC, ~~as well as information from Northshore,~~ to provide accurate and timely information in Mesabi Trust’s reports filed with the SEC.

In accordance with the Agreement of Trust and the Amendment, the Trustees are entitled to, and in fact do, rely upon certain experts in good faith, including (i) the independent consultants they have contracted with, with respect to monthly production and shipment reports, which include figures on crude ore production and iron ore pellet shipments, and discussions concerning the condition and accuracy of the scales and plans regarding the development of Mesabi Trust’s mining property; and (ii) the accounting firm they have contracted with for non-audit services, including reviews of financial data related to shipping and sales reports provided by Northshore and a review of the schedule of leasehold royalties payable to Mesabi Trust.

For a discussion of additional factors, including but not limited to those that could adversely affect Mesabi Trust’s actual results and performance, see “Risk Factors” set forth on pages 4 through 18 of Mesabi Trust’s Annual Report on Form 10-K for the fiscal year-ended January 31, 2026 (filed April 22, 2026), as supplemented by the “Risk Factors” set forth on page 18 of this Quarterly Report on Form 10-Q (Part II, Item 1A.) for the quarter ended April 30, 2026.

Iron Ore Pricing and Contract Adjustments

Cliffs has recently disclosed that marketing and selling iron ore pellets to third party customers in arms’-length transactions is no longer a core aspect of Northshore’s business. Historically, when Cliffs produced iron ore for arms’-length sales to third-party customers, some portion of the royalties Cliffs paid to Mesabi Trust were based in part on estimated prices for certain iron ore products sold under some of Cliffs’ customer contracts. Mesabi Trust is not a party to any of the Cliffs’ customer contracts. Generally, prices in some of such contracts were subject to interim and final pricing adjustments, which can be positive or negative, and which adjustments are dependent in part on a variety of price and inflation index factors, including but not limited to various benchmark pellet prices, hot band steel prices and various Producer Price Indexes. Although Northshore makes interim adjustments to the royalty payments on a quarterly basis, these price adjustments typically were not finalized until after the end of a contract year. In such circumstances, significant and frequent variations in royalties paid to the Trust could result. Iron ore products that are sold internally to Cliffs’ affiliates do not include such contract adjustment provisions.

Table of Contents

Potential distributions to Unitholders by the Trust can also vary significantly from quarter to quarter and on a comparative historical basis. These variations, which can be positive or negative, cannot be predicted by Mesabi Trust. It is possible that future negative price adjustments could partially or even completely offset royalties or royalty income that would otherwise be payable to the Trust in any particular quarter, or at year-end, thereby potentially reducing cash available for distribution to the Trust’s Unitholders in future quarters.

Effects of Securities Regulation

The Trust is a publicly traded, pass-through royalty trust with its Trust Certificates listed on the New York Stock Exchange (“NYSE”) and is therefore subject to extensive regulation under, among others, the Securities Act of 1933, the Securities Exchange Act of 1934, the Sarbanes-Oxley Act of 2002 (“Sarbanes-Oxley”), each as amended, and the rules and regulations of the NYSE. Issuers failing to comply with such authorities risk serious consequences, including criminal as well as civil and administrative penalties. In most instances, these laws, rules and regulations do not specifically address their applicability to a publicly-traded pass-through royalty trust such as Mesabi Trust. In particular, Sarbanes-Oxley mandated the adoption by the SEC and NYSE of certain rules and regulations that are impossible for the Trust to literally satisfy because of its nature as a pass-through royalty trust. Pursuant to NYSE rules, as a pass-through royalty trust, the Trust is exempt from many of the corporate governance requirements that apply to other publicly traded corporations. The Trust does not have, nor does the Agreement of Trust provide for, a board of directors, an audit committee, a corporate governance committee, a compensation committee or executive officers. The Trust has no employees. The Trustees closely monitor the SEC’s and NYSE’s rulemaking activities and will comply with their rules and regulations to the extent applicable.

Certain Tax Information

The Trust is not taxable as a corporation for federal or state income tax purposes and is instead qualified as a nontaxable grantor trust. Since the Trust’s inception, all net taxable income is annually attributable directly to Unitholders for tax purposes regardless of whether the income is distributed or retained by the Trust in its reserve account. As such, in lieu of the Trust paying income taxes, Unitholders report their pro rata share of the various items of Trust income and deductions on their income tax returns. This reporting is required whether or not the earnings of the Trust are distributed as to Unitholders. During calendar year ~~2024~~2026, any funds retained to increase the Trust’s unallocated reserve, which were derived from reportable royalty income and other proceeds, will nonetheless become taxable as reportable income to Unitholders, depending on each individual’s personal tax situation. Information regarding the background on the changes in the Trust’s unallocated reserve is described above under “Results of Operations — Comparison of Unallocated Reserve as of ~~October~~April 3130, ~~2025~~2026, ~~October~~April 3130, ~~2024~~2025 and January 31, ~~2025~~2026” beginning on page 1412. Unitholders are encouraged to consult with their own tax advisors to plan for any financial impact related to this and to review their personal tax situations related to investing in, holding or selling units of beneficial interest in Mesabi Trust.

Item 4. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures. The Trust maintains a system of disclosure controls and procedures designed to ensure that information required to be disclosed by the Trust in the reports that it furnishes or files under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the rules and regulations of the SEC. Due to the pass-through nature of the Trust, the Trust’s disclosure controls and procedures include controls and procedures designed to ensure that information required to be disclosed by the Trust is received from Cliffs and its wholly-owned subsidiary, Northshore. In order to help ensure the accuracy and completeness of the information required to be disclosed in the Trust’s periodic and current reports, the Trust employs certified public accountants, geological consultants, and attorneys. These professionals hired by the Trust advise the Trust in its review and compilation of the information in this Form 10-Q and the other periodic reports filed by the Trust with the SEC.

As part of their evaluation of Mesabi Trust’s disclosure controls and procedures, the Trustees rely on quarterly shipment and royalty calculations provided by Northshore and Cliffs. Because Northshore has declined to provide a written certification attesting to whether Northshore has established disclosure controls and procedures and internal controls sufficient to enable it to verify that the information furnished to the Trustees is accurate and complete, the Trustees also rely on (a) an annual certification from Northshore and Cliffs, certifying as to the accuracy of the royalty calculations, and (b) the related due diligence review performed by the Trust’s accountants. In addition, Mesabi Trust’s consultants review the schedule of leasehold royalties payable, and shipping and sales reports provided by Northshore against production and shipment reports prepared by Eveleth Fee Office, Inc., an independent consultant to Mesabi Trust (“Eveleth Fee Office”). Eveleth Fee Office performs inspections of the Northshore mine and its pelletizing operations, observes production and shipping activities, gathers production and shipping information from Northshore and prepares monthly production and shipment reports for the Trustees. Furthermore, as part of its engagement by Mesabi Trust, Eveleth Fee Office also attends Northshore’s calibration and testing of its crude ore scales and boat loader scales which are conducted on a periodic basis.

As of the end of the period covered by this report, the Trustees carried out an evaluation of Mesabi Trust’s disclosure controls and procedures. Based on this evaluation, the Trustees have concluded that such disclosure controls and procedures are effective.

Changes in Internal Control over Financial Reporting. To the knowledge of the Trustees, there were no changes in the Trust’s internal control over financial reporting that occurred during the Trust’s last fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Trust’s internal control over financial reporting. The Trustees note for purposes of clarification that they have no authority over, and make no statement concerning, the internal controls of Northshore or Cliffs.

AAA Arbitration

As previously announced, on September 26, 2025, Mesabi Trust initiated arbitration against Northshore Mining Company (“Northshore”) and its parent, Cleveland-Cliffs Inc. (“Cliffs”) (Northshore and Cliffs, jointly, the “Operator”), the lessee/operator of the leased lands. Mesabi Trust commenced the arbitration proceeding through the American Arbitration Association. Mesabi Trust seeks damages and declaratory relief relating to the Operator’s idling of Northshore’s operations from May 2022 to April 2023 and underpayment of royalties on intercompany shipments from 2023 through the present. The arbitration is in its early stages.

Item 1A. Risk Factors

The following Risk Factor supplements the Trust’s Risk Factors as described in “Risk Factors” as set forth inon pages 4 tothrough 1918 of Mesabi Trust’s Annual Report on Form 10-K for the fiscal year ended January 31, ~~2025~~2026 (filed April 2422, ~~2025~~2026).

~~Limited~~The ~~bona~~limited ~~fide~~arms’-length third-party sales ~~transactions~~ of iron ore products (processed at Northshore using Mesabi Trust iron ore) by Cliffs at prices below the annual adjusted bonus royalty threshold price eliminated a bonus royalty during the Trust’s fiscal quarter ended April 30, 2026, could continue to reduce or even eliminate bonus royalties historically paid to the Trust and could result in potential disputes regarding the amount of royalties owed to the Trust.

~~Since~~Mesabi ~~2005, the~~ Trust ~~has consistently been paid bonus royalties by the mine operator pursuant to the Royalty Agreement. The Trust~~ recognizes bonus royalties on a quarterly basis, based on the volume of shipments for each fiscal quarter at the actual royalty percentage for those shipments and based on the ~~anticipated~~ prices for iron ore products sold by Cliffs in bona-fide third-party transactions. The Trust is paid royalty bonuses when iron ore products shipped are sold at ~~anticipated~~ prices above a bonus threshold price per ton, which is calculated annually. The royalty bonus is based on a percentage of the gross proceeds of all iron ore ~~product~~products shipped that quarter. The royalty bonus percentage ranges from 1/2 of one percent of the gross proceeds (on all tons of iron ore shipped for sale at prices between the threshold price and $2.00 above the threshold price) to 3% of the gross proceeds (on all tonnage shipped for sale at prices $10 or more above the threshold price). The threshold price is adjusted annually for inflation and is $6971.4170 per ton for calendar year ~~2025.~~2026 ~~Although~~and 98was $69.3%41 ofper ~~all~~ton ~~the~~for ~~iron ore products shipped from Silver Bay during~~ calendar 2024 were sold at prices higher than the 2024 adjusted threshold price, the Trustees are unable to project whether Cliffs will continue to sell iron ore products at prices above the applicable adjusted threshold price, entitling the Trust to any future bonus royalty payments. Limited third-party customer sale transactions of iron ore products produced with iron ore mined from Mesabi Lands at prices below the adjusted threshold price could lead to uncertainty under the Royalty Agreement regarding the calculation of bonus royalties, which in turn could result in potential disputes regarding the amount of bonus royalties owed to the Trust. Furthermore, such developments could potentially reduce or even eliminate bonus royalties payable to the Trust during a particular quarter or year. 2025.

As recently reported by the Trust in its Current Report on Form 8-K dated May 4, 2026, based on Cliffs’ most recent quarterly royalty report of shipments to an unaffiliated third party customer for the three months ended March 31, 2026, the Trust was credited with a bonus royalty in the amount of $0 (zero dollars). In its April 30, 2026 quarterly royalty report to the Trust, Cliffs reported that all deemed shipments out of Silver Bay for the calendar quarter ended March 31, 2026 were priced below the 2026 adjusted bonus royalty threshold of $71.70 per ton. The prices Cliffs reported for deemed shipments in this quarter were based on a third-party sale that occurred in September 2025. Other than the time period related to Cliffs’ temporarily idling of Northshore operations from May 2022 to April 2023, this represents the first time in many years that Cliffs’ quarterly royalty report and royalty payment did not report and pay Mesabi Trust a bonus royalty for shipments of iron ore pellets made during the applicable quarter.

The Trustees are unable to project whether Cliffs will continue to sell iron ore products at prices above, at or below the applicable adjusted bonus royalty threshold price, making it uncertain as to whether the Trust will be paid any future bonus royalty payments. Limited third-party customer sale transactions of iron ore products produced with iron ore mined from Mesabi Lands at prices below the adjusted threshold price could lead to uncertainty under the Royalty Agreement regarding the calculation of bonus royalties, which in turn could result in potential disputes regarding the amount of bonus royalties owed to the Trust. Furthermore, such developments could potentially continue to reduce or eliminate bonus royalties payable to the Trust during a particular quarter or year.
