The Additional Mesabi Royalty doubles TMCR’s total royalty interest in the Mesabi Project to 2.0%. Assuming production at a rate of 7.28 Mtpa over a 23-year mine life, the Company anticipates potential annual royalty revenue of approximately US$22 million, with potential to increase to approximately US$26 million if the Mesabi Project achieves its contemplated expansion to 8.5 Mtpa.

“Doubling our royalty position at Mesabi to 2.0% is an important milestone for TMCR and a clear expression of our business strategy,” said Brian Paes-Braga, Executive Co-Chairman and Chief Executive Officer of TMCR. “We believe America spent too long outsourcing the minerals its economy and security depend on. We believe that Mesabi is a strategically important iron ore asset in the United States that will produce critical feedstock for American green steelmaking and support economic prosperity in Northern Minnesota. With Mesabi commissioning its project and TMC advancing the NORI project toward permitting and offshore commissioning at pace, we are building an America First mining finance platform to offer investors a diversified basket of exposure to the metals that matter most to every American, including nickel, copper, manganese, cobalt, and iron ore – with many others in our sights. Establishing a senior secured facility with Macquarie, one of the world’s leading resource banks, does more than fund this acquisition – it establishes a strategic relationship that may give us access to non-dilutive capital options as we scale and execute on our pipeline. I want to thank the Essar Group for their hard work in completing this transaction, Macquarie for anchoring our senior facility, and I am pleased to welcome EdgePoint and several new investors to our business. We expect this to be exactly the kind of long-duration, high-quality royalty stream this platform was built to acquire – and we look forward to continuing to build on this foundation as we work to execute on our pipeline of potential opportunities in the second half of this year.” Michael Hess, Non-Executive Co-Chairman of TMCR, added, “The Metals Royalty Company is proud to be a United States-focused finance business for the mining industry, an industry that has been neglected for several decades. There has never been a better time to support an industry so critical to our nation’s geopolitical and economic security. Brian and I want to personally welcome and thank our new institutional investors and specifically the Essar Group, who is now a major indirect shareholder in our business. We view this as a transformational moment for our company, and we could not be more excited about what the future holds.”

The net proceeds to the Company from the offering of the Notes and the Loan Facility, after deducting estimated fees, expenses, and original issue discount were approximately $150.9 million. The net proceeds of the Notes and the Loan Facility are being used: (i) to fund the closing of the Additional Mesabi Royalty, (ii) to repay in full the Company’s existing senior term loan facility and (iii) for general corporate purposes. In connection with the closing of the Additional Mesabi Royalty, the Company, Ironclad and Mesabi Investments (USA) LLC (“Mesabi Investments”), entered into an amending agreement to the royalty purchase agreement dated May 6, 2026, as amended, to: (i) increase the share consideration to an aggregate value of US$27.5 million (from US$7.5 million), resulting in the issuance of 4,365,079 common shares in a transaction exempt from the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”) and (ii) make a corresponding reduction in the cash consideration. Scotiabank and William Blair acted as placement agents for the Notes offering. An affiliate of Scotiabank also acted as financial advisor to Ironclad, the vendor of the Additional Mesabi Royalty, in connection with the sale of the Additional Mesabi Royalty, and a portion of the proceeds of the Notes offering is being used to fund the Company’s acquisition of the Additional Mesabi Royalty from Ironclad. The Notes and the warrants were offered and sold, and the common shares were issued to Mesabi Investments, as Ironclad’s nominee, in private placements in reliance on the exemption from the registration requirements of the Securities Act provided by Section 4(a)(2) thereof and, in the case of offers and sales outside the United States, Regulation S under the Securities Act, and on exemptions from prospectus requirements of applicable Canadian securities laws. The Company has agreed to file with the U.S. Securities and Exchange Commission a registration statement covering the resale of the common shares issuable upon conversion of the Notes, the common shares issuable upon exercise of the warrants and the common shares issued to Mesabi Investments.

Mesabi Metallics is completing a merchant DR-grade iron ore mine and pellet plant located on more than 16,000 acres in Nashwauk, northern Minnesota, one of the United States’ only new, large-scale sources of merchant DR-grade iron ore pellets and the critical feedstock for Electric Arc Furnace steelmaking and the domestic green steel industry. The project is backed by the Essar Group, one of the world’s most proven builders of world-scale industrial assets, which reports $15 billion in annual revenue, a 50-year operating track record, and a history of successfully building and operating multiple pellet plants of comparable scale, and has already invested over $2 billion of equity into the Mesabi Project. Mesabi Metallics is targeting commissioning of operations in H2 2026, subject to the completion of construction.
