This Amendment No. 3 to Schedule 13G amends and restates the statements on Schedule 13G originally filed on August 10, 2023, Amendment No. 1 filed on February 14, 2024, and Amendment No. 2 filed on November 14, 2024.
This joint statement on Schedule 13G (this "Statement") is being filed by Fairmount Funds Management LLC ("Fairmount"), Fairmount Healthcare Fund II L.P. ("Fund II"), Peter Harwin, and Tomas Kiselak. Fairmount, Fund II, Mr. Harwin, and Mr. Kiselak are collectively referred to herein as the "Reporting Persons."
On December 31, 2024, the Reporting Persons' beneficial ownership consisted of 2,194,341 shares of Common Stock representing 5.3% of the class's shares outstanding. As of the date of this filing, the Reporting Persons' hold no shares of Common Stock. Fairmount serves as investment adviser for Fund II and may be deemed a beneficial owner, for purposes of Section 13(d) of the Securities Exchange Act of 1934 (the "Act"), of any securities of the Issuer held by Fund II. Fund II has delegated to Fairmount the sole power to vote and the sole power to dispose of all securities held in Fund II's portfolio. Because Fund II has divested voting and investment power over the reported securities and cannot revoke such delegation on less than 61 days' notice, Fund II disclaims beneficial ownership of the securities for purposes of Section 13(d) of the Act and therefore disclaims any obligation to report ownership of the reported securities under Section 13(d) of the Act. As managing members of Fairmount, Mr. Harwin and Mr. Kiselak may be deemed beneficial owners, for purposes of Section 13(d) of the Act, of any securities of the Issuer beneficially owned by Fairmount. Fairmount, Mr. Harwin, and Mr. Kiselak disclaim beneficial ownership of the securities reported in this Statement other than for the purpose of determining their obligations under Section 13(d) of the Act, and the filing of the Statement shall not be deemed an admission that any of Fairmount, Mr. Harwin, or Mr. Kiselak is the beneficial owner of such securities for any other purpose. |
