Context
This was a vesting of performance RSUs (not a cash purchase). Part of the newly vested shares were sold immediately to satisfy tax withholding — a common, administrative action that does not necessarily signal the insider's view on the company. Note also the filing’s remark that on Jan 12, 2026 iRhythm Technologies completed a holding company reorganization and all prior shares/equity awards converted one-for-one to iRhythm Holdings securities with no change in holders’ proportional interests.
