Context
The 2,812-share disposition labeled “F” indicates shares were used to satisfy an exercise price or tax withholding (a common sell-to-cover/cashless exercise mechanism). The additional 6,000-share “S” entry was an ordinary open-market sale. Insider sales are routine and do not by themselves indicate management sentiment; purchases tend to be more informative about bullish conviction.
