Context

• This is an equity award/option grant, not a cash purchase or sale. The grant does not represent immediate cash value until (and unless) options vest and are exercised; future value depends on LeonaBio’s stock price and any exercise price/terms. Such grants are common for executive compensation and do not by themselves indicate immediate insider buying or selling.
