Insights

Insider Transaction Analyst

Officer withheld 4,021 shares at $22.67 for RSU tax withholding; retains 95,320 shares.

The filing documents a routine tax withholding tied to RSU vesting rather than an open‑market sale, indicating the disposition was administrative in nature and not an active divestiture. The report lists the transaction code F, which corresponds to a sale executed to cover tax obligations, and shows direct ownership remaining at 95,320 shares.

This is a single, clearly disclosed event; there are no derivative transactions reported and no additional material actions disclosed in the Form 4.
