Are you talking about the ones that see gifted after being there for one year?

If so, once they vest they’ll be available in 2 years. And then you can sell them.

Assuming you are US based, you'll have that as income that will be taxed when you do taxes next year. But there shouldn't be a withdrawal penalty if they are already issued, like the other person said.
Bean stocks are different than 401K/retirement funds. Those typically have a penalty because they are not intended to be used (withdrawn from) before you reach retirement age (presuming you are younger than your mid 60's).
