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

Current report

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.

Current report

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.

Current report

Cliffs also indicated that it has already moved from the trial phase to routine production and delivery of regular orders to the client. Cliffs said it has also received inquiries from other clients for programs that will replace aluminum with Cliffs steel, underscoring the growing confidence among automotive OEM’s in domestic steel and Cliffs’ supply reliability.

Previous report

On March 5, 2025, both the DNR and Northshore petitioned the Minnesota Supreme Court to review the Court of Appeals’ decision. The relator, WaterLegacy, opposed the petition and, on March 26, filed a motion to stay Northshore’s construction of the proposed project pending the resolution of the litigation. The DNR and Northshore both opposed the stay on substantive and procedural grounds. Northshore argued that any stay of its Milepost 7 tailings basin DNR Master Permit and five-year operating plan, “regardless of length, could require Northshore to cease operations at the Tailings Basin, which would necessitate the shutdown of Northshore’s iron ore pellet manufacturing operations entirely, and would result in significant economic harm to both Northshore and the local economy.”

(“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 award. As a result, the Trust recognizes revenue for 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.

Northshore as a swing operation. For the twelve-month period ended December 31, 2023, Cliffs has reported to the Trust two low volume shipments of iron ore pellets (produced from iron ore principally mined from Mesabi Trust Lands) to a single third-party customer. Cliffs’ quarterly royalty report used the highest price from those two transactions to set the price for royalty purposes for subsequent shipments intended for Cliffs’ affiliates internal consumption beginning in July 2023. For the twelve-month period ended December 31, 2024, Cliffs has reported to the Trust four low volume shipments of iron ore pellets (produced with iron ore principally mined from Mesabi Trust Lands) to a single third-party customer. Cliffs’ quarterly royalty report used the highest price from certain of those transactions to set the price for royalty purposes for subsequent shipments intended for Cliffs’ affiliates’ internal consumption beginning in July 2024, subject to the newly reported arms’-length third-party customer sales transactions thereafter. According to Cliffs’ quarterly royalty reports, beginning with the third calendar quarter of 2025, 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 decreased, resulting in a lower bonus royalty rate for the Trust beginning July 1, 2025. The Trust is continuing to evaluate whether such transactions meet the requirements of the Royalty Agreement. Without consistent arms’-length sales from Northshore to third parties, the calculation of royalties on iron ore 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.

Current wording

In order to calculate the royalties owed by Northshore to Mesabi Trust, the 1989 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, which Cliffs idled from May 2022 to April 2023. Cliffs also said it will continue to run Northshore as a swing operation. For the twelve-month period ended December 31, 2023, Cliffs has reported to the Trust two low volume shipments of iron ore pellets (produced from iron ore principally mined from Mesabi Trust Lands) to a single third-party customer. Cliffs’ quarterly royalty report used the highest price from those two transactions to set the price for royalty purposes for subsequent shipments intended for Cliffs’ affiliates internal consumption beginning in July 2023.

The increase in Unallocated Reserve as of July 31, 2025, as compared to July 31, 2024, is primarily the result of an increase in unallocated cash and cash equivalents offset by a decrease in accrued income receivable. The increase in the unallocated cash and cash equivalents portion of the Unallocated Reserve is in part attributable to a decrease in the distribution payable to $1,574,401 as of July 31, 2025, as compared to $3,936,003 as of July 31, 2024. The decrease in the accrued income receivable portion of the Unallocated Reserve is attributable to a decrease in pricing, including the decrease in the bonus royalty rate, in the last month of the fiscal quarter ended July 31, 2025 as compared to the prior comparable period.

Current wording

As set forth in the table below, Unallocated Reserve decreased from $95,324,736 as of October 31, 2024 to $21,087,860 as of October 31, 2025. The decrease in Unallocated Reserve as of October 31, 2025, as compared to October 31, 2024, is primarily the result of a decrease in unallocated cash and cash equivalents and a decrease in accrued income receivable. The decrease in the unallocated cash and cash equivalents portion of the Unallocated Reserve is in part attributable to AAA arbitration award being received as of October 31, 2024, which was subsequently distributed to unitholders. The decrease in the accrued income receivable portion of the Unallocated Reserve is attributable to a decrease in pricing, including a lower bonus royalty rate, in the last month of the fiscal quarter ended October 31, 2025 as compared to the prior comparable period.

Previous wording

The Trust’s Unallocated Reserve as of July 31, 2025 decreased by $546,517 to $22,781,200, as compared to the fiscal year ended January 31, 2025. The decrease in the Unallocated Reserve as of July 31, 2025, as compared to January 31, 2025, is the result of a decrease in unallocated cash and cash equivalents offset by an increase in the accrued income receivable and contract asset. The decrease in the unallocated cash and cash equivalents portion of the Unallocated Reserve is attributable to the extended maintenance shut down at Northshore in February 2025 during which minimal mining, production and shipment occurred. The increase in the accrued income receivable portion of the Unallocated Reserve is attributable to an increase in shipments in the last month of the fiscal quarter ended July 31, 2025 as compared to the last month of the fiscal year ended January 31, 2025. The increase in the contract asset portion of the Unallocated Reserve is attributable to estimates of variable consideration related to the shipments calendar year-to-date through July 31, 2025 as compared to only one month of calendar year-to-date shipments for the fiscal year ended January 31, 2025. See “Note 2” for further discussion of contract asset and contract liability.

Cliffs’ Royalty Report also indicated that royalty calculations are based on prices that are subject to change.

Previous wording

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

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 Milepost tailings basin project. Consistent with the relief sought from the Minnesota Supreme Court, 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.

In order to calculate the royalties owed by Northshore to Mesabi Trust, the 1989 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, which Cliffs idled from May 2022 to April 2023. Cliffs also said it will continue to run
