Context PSUs are compensation that convert to shares when performance targets are met; these are not open-market purchases or sales and therefore aren’t a direct market signal like insider buys or sells. The vesting reflects achievement of a company EPS goal for 2025 and is routine compensation-related reporting for directors and executives.
