In April 2025, the Company granted PSUs to certain employees. The number of PSUs granted represents the target number of units that are eligible to be earned based on certain market-based conditions, subject to continued employment through applicable service vesting dates. The Company concluded that issued PSUs are equity-based awards and include market and service-based vesting conditions. Participants may ultimately earn up to 250% of the target number of units granted based on the degree of actual performance metric achievement. The Company estimated the fair value of these PSUs using a Monte-Carlo simulation model at the grant date. The Monte Carlo simulation model requires key inputs including risk-free interest rate, dividend yield and historical volatility.

No PSUs vested during the six months ended June 30, 2025.
