Context

• The March 10 withholding reflects a net settlement of RSUs (company withheld shares to cover taxes), which is administrative and not a market sale by the insider. The March 11 sale was carried out under a pre-established 10b5-1 plan, meaning the trades were scheduled under an automatic plan and are generally considered routine. As always, insider sales can be for many personal or administrative reasons and don’t by themselves indicate company performance.
