You have to have a fidelity account set up to claim the grants, unfortunately if you don’t then you may have missed the deadline to claim them :(
Also if you do happen to log in and see that you have grants that have been credited to your account , they will list the date that they “vest” for example I have two grants that vest on 11/11/2022
So I will be able to sell them at that date. This money will be able to transfer to your bank account that you will need to have linked. There can be small fees for the transfer of the funds, and you will have to claim the grants that you sold on your yearly income tax report, so that they can be taxed accordingly. So I’d set back a few hundred depending on how much you have to sell to pay taxes on them.

I’m in the same boat, I need to go in and talk to fidelity. I know you have to vest them, but idk what that does.
