Date Insider Role Action Shares Price Value Held after
Thomas Stephen Basil Director Sell 10b5-1 100,000 $13.67 $1.4M 467,969 −17.6% of holding

Form 4s are due within two business days of a transaction, so this is close to real time — unlike the quarterly 13F data on the Institutional tab. A single large sale often reflects a prearranged 10b5-1 plan rather than a fresh view, so read a pattern of sales rather than any one of them.
