Context

Pre‑funded warrants function like a short‑term right to obtain common shares; they are typically used to avoid immediate voting/ownership limits and are exercisable into common stock subject to the stated ownership cap.
The filing indicates institutional/managerial relationships (NEA entities), so this activity reflects an investor/affiliate acquisition rather than a routine employee tax or option exercise sale. As always, purchases are factual signals of buying interest but do not guarantee future company performance.
