Context

• This was an option exercise followed by immediate open-market sales (a cashless-style outcome): Hall paid the exercise cost to acquire shares and then sold them. The trades were prearranged under a 10b5-1 plan, which specifies timing and can limit the interpretive value of sales as a signal of current sentiment. The vesting footnote indicates the options became exercisable under a scheduled vesting plan beginning in April 2024.
