Context

• This was a compensation-related settlement of RSUs (a non‑cash event), not an open‑market buy or sale. Such conversions typically reflect standard equity compensation vesting rather than a deliberate market-timing trade by the insider. The derivative conversion (code M) simply reflects the RSU-to-share settlement; no immediate sale or cash proceeds were reported.
