Mirum (MIRM) SVP Jolanda Howe Sells 842 Shares
What Happened Jolanda Howe, SVP & Global Controller of Mirum Pharmaceuticals (MIRM), had restricted stock units convert to common shares on Jan 23, 2026 and then sold 842 shares in the open market on Jan 26, 2026. The Jan 23 filing shows 1,500 shares acquired via exercise/conversion of a derivative (related to RSUs) and a simultaneous reported disposition of 1,500 shares at $0 (consistent with shares withheld/settled in connection with vesting). On Jan 26 she sold 842 shares at $96.19 per share, generating $80,994. These transactions appear to be routine vesting and tax-withholding activity rather than a fresh purchase.
