- Footnotes: F1 clarifies each RSU equals one share on vesting; F2 confirms the sale was broker-assisted to cover tax withholding; F3 outlines the RSU vesting schedule (25% annually from 3/1/2024).
- Filing: Form 4 filed 2026-03-10 (covers transactions dated Mar 1–2, 2026) — this appears to be later than the standard two-business-day Form 4 reporting window.
- Shares owned after the transaction were not specified in the provided excerpt; net newly retained shares from this event = 3,166.
Context
- This was a routine vesting of RSUs with a broker-assisted sale to satisfy tax withholding (common practice). The conversion was not a paid purchase (no cash outlay); the partial sale is not necessarily a signal about company outlook.
- Not a 10% owner transaction; this is an executive's compensation vesting and related tax-sale activity.
