"The performance period for the performance restricted stock units was January 1, 2023 to December 31, 2025"
The performance period is the specific time span over which an investment’s results, an employee’s targets, or a fund’s returns are measured and judged. It matters to investors because the length and start/end of that window determine which gains or losses count toward performance fees, bonus payouts, or benchmark comparisons—much like timing a race decides who wins, the chosen period can change whether results look strong or weak.
