Insights

Corporate Governance Analyst

Director received time‑based RSUs totaling 8,736 that vest in one year.

The award reflects a common governance practice of granting restricted stock units to directors as deferred, time‑based compensation rather than immediate cash. The Form 4 shows the units were acquired at a reported price of $0, indicating the grant is a compensation issuance rather than a market purchase.

This transaction depends on continued service through 10/03/2026 to vest and creates a direct alignment between the director and shareholders over the vesting year. Investors may note the grant size of 8,736 RSUs when assessing director compensation levels relative to peers over the next 12 months.
