Positive

Negative

• Unclear line item: The form lists an additional 8,809 shares disposed without an associated price, leaving the economic details of that entry unspecified.

Insights

Securities Analyst

TL;DR: Insider sold shares to cover tax on vested restricted stock; this is routine and provides limited new information.

The reported disposition of 2,257 shares at $29.26 to satisfy tax withholding is a common administrative transaction following equity vesting and does not by itself indicate a change in company fundamentals or governance. The filing shows post-transaction direct ownership of 24,914 shares, which helps confirm continuing ownership. The separate line showing 8,809 shares disposed lacks an accompanying price on the form, so its economic terms are unclear from this document alone.

Corporate Governance Expert

TL;DR: Filing documents required disclosure of insider share withholding; it reflects compliance with reporting rules rather than a strategic disposition.

Withholding shares to satisfy tax obligations on vested restricted stock is standard practice and generally viewed as compliance activity. The report clarifies the reporting person’s role (EVP/Chief Banking Officer) and shows timely disclosure (signature dated 08/25/2025). The unexplained 8,809-share disposition entry reduces clarity; the form does not specify price or whether that line relates to the same vesting event or a separate transaction.
