Key Details
- Transactions date: 2026-06-09; Form 4 filed: 2026-06-11 (filed within the normal 2-business-day window).

Context
- Code M indicates an exercise or conversion of a derivative instrument (e.g., options or similar). The filing shows both an acquisition and a disposition of the same 2,370 derivative shares on the same date; the Form 4 does not state cash proceeds or explain whether this was a net/cashless settlement or a transfer for tax withholding.
- The award line (A) reflects new RSUs granted; vesting is time-based per the footnotes. These RSU awards are not the same as an open-market purchase and do not by themselves signal buy/sell intentions.
