Insights

Corporate Governance Analyst

Officer received time‑vested RSUs and completed a small share sale the same day.

The reported 175 RSUs are standard long‑term compensation that vest 25% annually over four years from 10/04/2021, aligning the officer's interests with shareholders through future equity delivery. The filing also notes a contemporaneous disposal of 85 shares at $38.49, reducing direct holdings to 38,101 shares.

Governance risks are routine: the grant is subject to multi‑year vesting and the sale is an ordinary disposal; there are no indications of extraordinary transfers or derivative use. Monitor ongoing vesting anniversaries for incremental share increases and future Section 16 filings within typical reporting timeframes.
