You need to look up how Equities work. This looks like an RSU grant of 600K; there are different vesting schedules (i.e. how much of the RSU becomes actual shares in the company, owned by you which you can sell/keep). Typically its 25% every year with a 1 year cliff (i.e. you get 0 actual shares when you start, but 25% after a year and so on).
