For retail investors, option grants indicate potential future ownership if vesting and any exercise conditions are met; they are not immediate purchases of common stock. The disclosable arrangement shows the option is held for investment vehicle(s) managed by Fairmount and that Mr. Kiselak and Fairmount disclaim direct beneficial ownership beyond any pecuniary interest.
