Insights

TL;DR: Routine insider tax-withholding event; modest reduction in direct holdings, no new sales for cash disclosed.

The Form 4 records a disposition coded as F on 08/29/2025 for 6,599 shares at $58.48, which the filer explains were withheld to satisfy tax obligations upon vesting. Post-transaction direct beneficial ownership is 61,046 shares including 35,419 restricted shares, and indirect holdings of 3,890 shares are held by spouse (including 2,913 restricted shares disclosed with a disclaimer). This is a non-market-impacting administrative transaction rather than an open-market sale or purchase, and the filing contains no additional derivative or option activity.

TL;DR: Disclosure meets Section 16 requirements; details clarify restricted share treatment and spouse holdings.

The report clearly documents the nature of the disposition as mandatory tax withholding on vested restricted stock and distinguishes direct versus indirect ownership with a disclaimer for certain spouse-held restricted shares. From a governance and compliance perspective, the submission appears complete for the cited transactions and identifies the reporting person’s role as Vice President and CFO, satisfying identification and timing elements required by Form 4.
