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 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, renewable energy, 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 track record of driving outsized

direct returns from its overall royalty investment portfolio. Altius has 55,915,754 common shares issued and

outstanding that are listed on Canada’s Toronto Stock Exchange. It is a member of both the S&P/TSX Small

Cap and S&P/TSX Global Mining Indices and the S&P/TSX Canadian Dividend Aristocrats Index.
