2025 Adjusted EBITDA of $45.8 million ($0.99 per share) compared to $44.1 million ($0.95 per share) in 2024. Adjusted EBITDA⁽¹⁾ of $15.6 million ($0.34 per share⁽¹⁾) during Q4 2025 compared to $9.3 million ($0.20 per share) during Q4 2024. Adjusted EBITDA for both periods followed the trend of revenue.

Full year adjusted operating cash flow of $27.5 million ($0.59 per share) compared to $24.8 million ($0.53 per share) in 2024. Q4 2025 adjusted operating cash flow⁽¹⁾ of $3.2 million ($0.07 per share⁽¹⁾) compares to $2.3 million ($0.05 per share) in Q4 2024. The increase reflects higher royalty receipts and interest offset by taxes paid and working capital changes.

Net earnings for the year ended December 31, 2025 of $299.4 million ($6.45 per share) compared to $101.8 million in 2024 ($2.16 per share). Net earnings of $22.5 million ($0.48 per share) for Q4 2025 compared to net earnings of $85.5 million ($1.82 per share) in Q4 2024. Net earnings in 2025 were positively impacted by the gain on sale of the Arthur Gold royalty interest as well as lower amortization, interest and other costs partially offset by an increased loss from joint venture which included an impairment charge on a development portfolio at GBR. Net earnings in 2024 were positively impacted by the gain on deconsolidation of ARR. Adjusted net earnings per share⁽¹⁾ of $0.49 and $0.24 for the year ended December 31, 2025 and Q4 2025 is higher than the $0.27 and $0.06 per share comparable periods in 2024.

Dividend Declaration

The Corporation's board of directors has declared a quarterly dividend of $0.10 per share, payable to all shareholders of record at the close of business on March 19, 2026. The dividend is expected to be paid on or about April 02, 2026.

This dividend is eligible for payment in common shares under the Dividend Reinvestment Plan (DRIP) announced by press release May 20, 2020, and available to shareholders who are Canadian residents or residents of countries outside the United States.

In order to be eligible to participate in respect of the April 02, 2026 dividend, non-registered shareholders must provide instruction to their brokerage and registered shareholders must provide completed enrollment forms to the transfer agent by March 11, 2026, five business days prior to record date. Stock market purchases made under the DRIP for the April 02, 2026 payment will be satisfied by issuance from treasury at the 5 day volume weighted average price ending at the close of trading the day before payment date. Shareholders who have already provided instruction to be enrolled previously will continue to be enrolled unless they direct otherwise. For more information, please see Altius Minerals Corporation Dividend Reinvestment Plan. Participation in the DRIP is optional and will not impact any cash dividends payable to shareholders who do not elect to participate in the DRIP. The declaration, timing and payment of future dividends will largely depend on the Corporation's financial results as well as other factors. Dividends paid by Altius on its common shares are eligible dividends for Canadian income tax purposes unless otherwise stated.

Non GAAP Financial Measures

Management uses the following non-GAAP financial measures: attributable revenue, attributable royalty revenue, adjusted earnings before interest, taxes, depreciation and amortization (adjusted EBITDA), adjusted operating cash flow and adjusted net earnings (loss). Management uses these measures to monitor the financial performance of the Corporation and its operating segments and believes these measures enable investors and analysts to compare the Corporation's financial performance with its competitors and/or evaluate the results of its underlying business. These measures are intended to provide additional information, not to replace International Financial Reporting Standards (IFRS) measures, and do not have a standard definition under IFRS and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. As these measures do not have a standardized meaning, they may not be comparable to similar measures provided by other companies. Further information on the composition and usefulness of each non-GAAP financial measure, including reconciliation to their most directly comparable IFRS measures, is included in the non-GAAP financial measures section of our MD&A.

About Altius

Altius's strategy is to create per share growth through a diversified portfolio of royalty assets that relate to long life, high margin operations. This strategy further provides shareholders with exposures that are well aligned with sustainability-related global growth trends including the electricity generation transition from fossil fuel to renewables, transportation electrification, reduced emissions from steelmaking and increasing agricultural yield requirements. These macro-trends each hold the potential to cause increased demand for many of Altius's commodity exposures including copper, renewable based electricity, several key battery metals (lithium, nickel and cobalt), clean iron ore, and potash. In addition, Altius runs a successful Project Generation business that originates mineral projects for sale to developers in exchange for equity positions and royalties. Altius has 55,915,754 common shares issued and outstanding that are listed on Canada's Toronto Stock Exchange. It is included in each of the S&P/TSX Small Cap, the S&P/TSX Global Mining, and the S&P/TSX Canadian Dividend Aristocrats indices.
