Between 2020 through 2021, in conjunction with equity offerings, the Company issued units at varying prices per unit in CAD, with each unit comprised of one Common Share and one-half of one Common Share financing warrant (each whole warrant, a “CAD Financing Warrant”). The Company also issued compensation warrants to its underwriters (the “CAD Compensation Warrants”). All CAD Financing Warrants and the CAD Compensation Warrants expired as of March 9, 2024.

On September 30, 2022, the Company closed an underwritten public offering of 7,058,823 Common Shares and accompanying 2022 USD Financing Warrants to purchase 7,058,823 Common Shares. Each 2022 USD Financing Warrant is immediately exercisable for one Common Share at an initial exercise price of $4.25 per Common Share, subject to certain adjustments, and will expire on September 30, 2027.
