During the nine months ended September 30, 2026 and 2025, the Company granted PSUs that vest in 4 tranches upon the Company’s common shares achieving four progressively higher target prices, and each tranche is further subject to a one year service period following target price achievement. During the nine months ended September 30, 2026, the Company also granted PSUs that vest in 2 tranches at the 3- and 5-year anniversary date of the grant upon the Company’s common shares achieving specified target prices that represent significant increases from the share price on the date of grant before the respective vesting date. The Company estimated the fair value of each PSU with a market and service condition on the date of grant by using a Monte Carlo simulation (lattice model).
Beginning in 2026, RSUs are no longer being granted. RSUs granted prior to 2026 vest in 3 equal annual installments on the first, second and third anniversary of the grant date. The fair value of RSUs is based on the market price of the Company’s common shares on the date prior to the grant.
