"Represents shares that were withheld to satisfy tax withholding obligations upon vesting of restricted stock units."

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

Did AEHR VP Alistair Sporck sell shares on the open market?

What does transaction code F mean in the AEHR Form 4 filing?

Transaction code F indicates shares used to pay an exercise price or tax liability. In this case, 341 shares were withheld to cover tax obligations when restricted stock units vested, as described in the footnote, and are not considered a market sale.
