Insights

Insider Transactions Analyst

TL;DR: EVP sold 10,918 shares via tax-withholding after RSU vesting on 04/01/2025.

What it means: The reported 10,918‑share disposition is documented as a tax withholding related to RSU vesting rather than a market sale for cash, which means the company retained those shares to satisfy taxes on behalf of the insider.

Why it matters: Tax‑withholding dispositions are routine compensation mechanics and generally carry different signaling than voluntary open‑market sales. The filing shows the insider still holds 73,219 shares directly, so ownership remains material.

Monitor subsequent Form 4 filings for any additional open‑market transactions or changes in beneficial ownership.
