Insights

Corporate Governance Analyst

Director received a standard long-term equity award to align interests.

Granting 36,000 options at $27.52 ties the director's compensation to future share performance over a roughly ten-year horizon to the expiration date of 10/05/2035.

The monthly 1/36 vesting schedule beginning 11/06/2025 conditions value on continued service; monitor executive departures or additional grants over the next 12 months for governance signal.

Compensation Analyst

Vesting and strike details indicate multi-year retention focus.

The exercise price of $27.52 and the extended expiration provide potential upside only if the share price rises above the strike before 10/05/2035. The award vests monthly, creating a steady retention mechanism rather than a single cliff.

Investors may watch reported share counts or future equity compensation disclosures to assess dilution; the filing shows the immediate incremental grant amount of 36,000 options.
