Date Insider Role Action Shares Price Value Held after
LO FRANCIS 2 fills Chief People Officer Sell 10b5-1 115,406 $28.06 $3.2M 228,736 −33.5% 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.
