Insights

Corporate Governance Expert

Director awarded 4,126 RSUs to align incentives with shareholders.

This grant to Ian David Haft is a board-level equity award that vests in one year on 10/01/2026, tying potential ownership to continued board service. Such awards are common for directors and indicate compensation is equity-linked rather than cash-based.

The settlement condition—conversion of vested RSUs into shares upon board departure—means the reporting person receives shares only after service termination, preserving alignment while controlling immediate dilution.

Compensation Analyst

Grant size (4,126 RSUs) is modest and specific to director compensation.

The award has $0 purchase price and standard one-year vesting, suggesting a retention and alignment incentive rather than immediate compensation. The filing shows 4,126 underlying shares will be issued upon settlement, which is a precise, quantifiable change to outstanding equity when settled.
