Aehr Test Systems CFO Chris Siu reported the vesting of restricted stock units on 10/02/2025. To satisfy tax withholding on the vesting event, 694 shares were withheld at a price of $32.25, which the filer notes is not a sale.

Insights

Corporate Insider

Insider withheld 694 shares for taxes after RSU vesting on 10/02/2025.

This Form 4 discloses a tax-withholding action tied to vesting of restricted stock units; the filer explicitly states the withheld 694 shares were not sold. That means the economic event was a vesting/tax settlement, not an active disposition of shares into the market.

The filing shows continuing beneficial ownership of 75,535 shares directly and 5,211 shares indirectly by trust, with unvested RSUs included in reported amounts. For investors, this is a routine reporting step documenting insider compensation mechanics rather than a signal of strategic share selling.
