During the three months ended June 30, 2021, the fiscal year 2019 PSUs vested and were paid at 280% of target, based on actual performance results and completion of service conditions. In addition, the PSUs granted to employees of Gyros Protein Technologies Holding AB vested at 60% of target, following a modification of the performance targets by the Compensation Committee of the Board of Directors during fiscal year 2021.
