Insights

Compensation and Insider Activity Analyst

TL;DR: Senior executive received a large RSU grant and completed partial vest/transfer activity, modestly sold shares.

The 55,278 RSU grant represents a typical long‑term equity award aligning executive pay with shareholder returns; the RSUs vest in three equal annual tranches beginning 10/06/2026, which phases dilution and links value realization to continued service. The filing shows immediate movement: 12,165 shares recorded as acquired (code M) on 10/07/2025 and 4,787 shares sold the same day at $33.12, indicating routine vesting/settlement and partial disposition.

Dependencies and risks include share price volatility between vesting and sale dates and the impact of future vesting on share count and potential dilution; monitor annual vesting tranches over the next 2–3 years and any additional open trading plans filed that would govern future sales.
