FAQ

What insider transaction did AEHR CTO report on January 27, 2026?

The AEHR CTO reported tax-related share withholding, not an open-market sale. On 01/27/2026, 117 common shares were withheld at $27.75 per share to satisfy tax obligations from vesting restricted stock units, as disclosed in the Form 4 footnotes.

How many AEHR shares were withheld for taxes in this Form 4?

A total of 117 AEHR common shares were withheld for taxes. The Form 4 states these shares were retained by the company to satisfy tax withholding obligations arising from the vesting of restricted stock units and do not represent a sale by the reporting person.

Does the AEHR CTO’s Form 4 indicate a sale of shares?

No, the Form 4 specifies the transaction is not a sale. The filing explains the 117 shares were withheld solely to meet tax withholding obligations upon restricted stock unit vesting, and explicitly notes this does not represent a sale by the reporting person.

How many AEHR shares does the CTO beneficially own after this transaction?

After the transaction, the CTO beneficially owns 213,217 shares. The Form 4 states this amount includes shares underlying unvested restricted stock units, all reported as directly owned following the 117-share tax withholding on January 27, 2026.

What role does restricted stock play in the AEHR CTO’s ownership?

The CTO’s reported holdings include unvested restricted stock units. The Form 4 notes that the 213,217 beneficially owned shares encompass shares subject to unvested restricted stock units, indicating part of his equity stake is tied to ongoing vesting conditions.

What is transaction code “F” in the AEHR CTO’s Form 4 filing?

Code “F” reflects tax withholding related to equity vesting. The Form 4 uses transaction code F for the 117-share event, which the footnote explains as shares withheld to satisfy tax obligations from vesting restricted stock units, rather than a voluntary purchase or sale.
