Insights

Equity compensation and insider transactions analyst

Routine vesting and tax sale; neutral signal.

The officer converted equity awards on 10/10/2025 into common stock and executed a small sale of 3,670 shares at $23.41 on 10/13/2025. Footnotes state the sale was under a Rule 10b5-1 plan and to cover taxes associated with RSU/PSU settlements.

After these actions, direct beneficial ownership is 175,690 shares. The filing also lists continuing unvested RSUs and PSUs; RSUs/PSUs convert one-for-one into common stock. This appears administrative rather than thesis-changing, with activity determined by award vesting and tax obligations.
