Adsett Roger 4

What Happened Roger Adsett, Chief Operating Officer of INSMED Inc. (INSM), disposed of 791 shares on February 3, 2026 at $156.17 per share, for a total of approximately $123,530. The filing reports the sale as an open-market or private sale and the reported reason (footnote) was to satisfy tax withholding obligations upon the vesting of Restricted Stock Units (RSUs) and to cover related broker fees. This was a sale (not a purchase), which in this case appears to be a routine tax-withholding disposition rather than a directional trade.
