ALTIUS MINERALS CORPORATION CLOSES C$181.5 MILLION "BOUGHT DEAL" PUBLIC OFFERING OF COMMON SHARES

Altius Minerals Corp. has completed its previously announced bought deal public offering of three million common shares of the company at a price of $60.50 per common share for aggregate gross proceeds of $181.5-million.

The offering was conducted by a syndicate of underwriters, with National Bank Financial Inc., Scotia Capital Inc. and TD Securities Inc. acting as co-bookrunners, together with ATB Capital Markets Corp., Canaccord Genuity Corp., Raymond James Ltd. and BMO Capital Markets.

The company intends to use the net proceeds of the offering to strengthen the company's balance sheet following the completion and announcement of several acquisitions to date in 2026 as well as for general corporate purposes. Together with Altius's credit facilities that are currently being adjusted and expanded to reflect the integration of its acquisitions, the net proceeds of the offering will bolster Altius's liquidity and better position it to consider additional accretive opportunities while maintaining its conservative leverage profile.

About Altius Minerals Corp.

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 global growth trends including increasing electricity-based market share within energy usage, global infrastructure build and refurbishment growth, increased EAF-based steelmaking, steadily increasing agricultural fertilizer requirements and the enhanced appetite for financial asset diversification through precious metals ownership. These macro trends each hold the potential to cause higher demand for many of Altius's commodity exposures including potash, high-purity iron ore, electricity, base metals and gold. In addition, Altius runs a successful Project Generation business that originates mineral projects for sale to developers in exchange for royalties and that has a demonstrated record of driving outsized direct returns from its overall royalty investment portfolio. Altius's common shares are listed on Canada's Toronto Stock Exchange. It is a member of the S&P/TSX Composite, S&P/TSX Global Mining Indices and the S&P/TSX Canadian Dividend Aristocrats Index.
