This Amendment No. 2 amends and supplements the statement on Schedule 13D originally filed with the Securities and Exchange Commission on July 21, 2023 and Amendment No. 1 filed on January 31, 2024 (as amended, the “Statement” or the “Schedule 13D”) by the Reporting Persons with respect to the common stock, $0.00001 par value (“Common Stock”), of Apogee Therapeutics, Inc.

Fairmount Funds Management, Fairmount GP, Mr. Harwin and Mr. Kiselak disclaim beneficial ownership of the securities reported in this Schedule 13D other than for the purpose of determining their obligations under Section 13(d) of the Act, and the filing of this Schedule 13D shall not be deemed an admission that any of Fairmount Funds Management, Fairmount GP, Mr. Harwin or Mr. Kiselak is the beneficial owner of such securities for any other purpose.

 

(b) The principal business address of each of the Reporting Persons is 200 Barr Harbor Drive, Suite 400, West Conshohocken, PA 19428.
