Context
This filing reflects a corporate spin-off distribution, not a purchase or a market sale, so it doesn't signal executive buying or selling intent. Because AnaptysBio previously held all outstanding shares and distributed them to its shareholders, AnaptysBio no longer holds those First Tracks shares after the distribution.
