Insights

Corporate Governance Expert

TL;DR: CEO reported a small disposition tied to tax withholding after RSU vesting; ownership remains substantial.

The Form 4 shows a 09/30/2025 disposition of 23,508 shares at $17.94, recorded under code F(1), which the filer explains were withheld to satisfy tax withholding on vested restricted stock units. This is a common administrative sale linked to compensation rather than a signaling trade.

The filing also confirms continued large beneficial ownership of 4,363,600 shares and documents receipt of 3,555 shares on 07/17/2025 via an in-kind distribution exempt under Rule 16a-9. The combination of vesting, withholding, and an exempt in-kind distribution are all explicitly disclosed in the Form 4.
