Performance-Based Restricted Stock Units

As of December 31, 2025, the Company has granted 138,144 PRSUs to certain of its officers and directors under its 2013 Equity Incentive Plan (as amended and restated), that will vest in one tranche to the extent earned, contingent upon the Company’s relative total shareholder return (“TSR”), which represents a market condition, and the grantee’s continued employment with the Company through the vesting date.

The TSR is calculated based on the Company’s total shareholder return compared to that of certain peer companies specified in the award agreements over the performance period and is calculated based on the change in the average daily closing stock price over a 30 trading-day period from the beginning to the end of the performance period, including reinvested dividends. The total quantity of PRSUs eligible to vest under these awards range from zero to 200% of the target based on actual relative TSR performance during the performance period. The grant date fair value of the TSR awards was estimated using a Monte Carlo simulation model. Compensation for these awards is being amortized over the service period.
