Form 4 raw → Raspberry

The value is in what we do not call a signal.

The SEC XML stores every transaction. Raspberry keeps that evidence, reads the footnotes and separates voluntary open-market activity from vesting, option exercises, gifts, tax withholding, stock purchase and dividend reinvestment plans and pre-programmed 10b5-1 trades.

Fairmount Funds Management LLC ("Fairmount") is the investment manager for Fairmount Healthcare Fund II L.P. The managers of Fairmount are Peter Harwin and Tomas Kiselak. Fairmount, Mr. Harwin, and Mr. Kiselak disclaim beneficial ownership of any of the reported securities, except to the extent of their pecuniary interest therein. This option represented the vested portion of the total right to purchase 47,758 shares of the Issuer's common stock, which vested in three approximately equal annual installments beginning on the first anniversary of the 7/13/2023 grant date. Under Mr. Harwin's arrangement with Fairmount Funds Management LLC (the "Adviser"), Mr. Harwin held the options reported herein for one or more investment vehicles managed by the Adviser (each, a "Fairmount Fund"). Mr. Harwin was obligated to turn over to the Adviser any net cash or stock received from the options for the benefit of such Fairmount Fund. Mr. Harwin therefore disclaimed beneficial ownership of the option and underlying common stock. This option represented the right to purchase 10,370 shares of the Issuer's common stock, which vested on the one-year anniversary of the 6/5/2024 grant date.
