Key Details

Transaction dates: Feb 6–7, 2026 (conversion); tax withholding reported Feb 6 and Feb 9, 2026. Filing date: Feb 10, 2026; Period of Report: Feb 6, 2026.

Shares owned after transaction: not specified in the filing (the form lists RSU activity and withholding but does not state total post-transaction holdings).

Exhibit: Exhibit 24 — Power of Attorney. No indication this filing was late.

Context

This was a routine RSU vesting/conversion event, not an open-market buy or sale driven by trading intent. The withheld shares reflect tax withholding (a common cashless settlement), not an active sale to realize gains. Purchases typically signal stronger insider confidence; conversion and withholding are standard compensation mechanics.
