A bit unusual compared with their history

Score 22 of 100, from 2 reasons.

  • Not part of a pre-scheduled plan

    Insiders can set up trades months ahead (a 10b5-1 plan). The filing dated Sep 4, 2026 does not mark this trade as one of those. 1 of their 1 earlier sale in our records were pre-scheduled.

    +12

  • Sold 22% of their holding

    The filing shows their holding going from 6,388 to 4,988 shares.
