"The amount reported includes shares subject to unvested 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.

FAQ

How many AEHR shares did the insider sell and at what prices?
The insider sold 2,000 shares of Aehr Test Systems common stock: 699 shares at $100.695 per share and 1,301 shares at $101.10 per share. Both transactions are reported as sales in open market or private transactions.

What AEHR share holdings does Alistair N. Sporck report after these transactions?
The filing reports 5,177 shares of Aehr Test Systems common stock held indirectly "By Trust". This entry reflects indirect ownership via a trust structure; the filing does not state a consolidated total of all direct and indirect holdings after the reported sales.

What does the restricted stock units footnote mean in the AEHR Form 4?
A footnote explains that the amount reported includes shares subject to unvested restricted stock units. This means some of the shares reflected in the reported amount are tied to unvested RSUs, which remain subject to vesting conditions rather than being fully unrestricted stock.

Are the reported AEHR holdings direct or indirect for the trust position?
The holding entry for 5,177 shares is classified as indirect ownership with the nature of ownership described as "By Trust". This indicates the shares are held through a trust rather than directly in the insider’s own name.
