During the six months ended June 30, 2026, pursuant to the Company's 2020 Equity and Incentive Compensation Plan, the Company granted performance share awards with a total shareholder return component ("TSRs"). These performance share awards are earned, if at all, based upon achievement, over a specified period that must not be less than one year and is typically a three-year performance period. The awards have operating performance goals that include (i) adjusted EBITDA metrics and (ii) revenue growth rates as determined by the Company with a TSR multiplier up to plus or minus 20%. Up to 200% of the performance shares could be earned upon achievement of the performance goals, including the multiplier. On a quarterly basis, management evaluates the probability that the threshold performance goals will be achieved, if at all, and the anticipated level of attainment to determine the amount of compensation expense to record in the consolidated financial statements.
