restricted stock units financial

"upon vesting of restricted stock units. This does not represent a sale"

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.

tax withholding obligations financial

"shares that were withheld to satisfy tax withholding obligations upon vesting"

Form 4 regulatory

"On this Form 4, 102 shares of common stock were withheld"

Form 4 is a official document that company insiders, such as executives or major shareholders, file with regulators whenever they buy or sell company shares. It provides transparency about how those with inside knowledge are trading, helping investors see if insiders are confident in the company's prospects or may be selling for personal reasons. This information can influence investor decisions by revealing insiders' perspectives on the company's value.

What insider transaction did AEHR CTO Donald P. Richmond II report?

Donald P. Richmond II reported 102 AEHR common shares withheld for taxes. The shares covered tax obligations from vesting restricted stock units, rather than an open-market sale, and are recorded at a price of $88.48 per share.

Was the AEHR CTO’s Form 4 transaction a stock sale in the market?

No, the filing states the 102 shares were withheld for tax obligations. A footnote explicitly explains this does not represent a sale by the reporting person, but a tax-withholding mechanism tied to restricted stock unit vesting.

How many AEHR shares does the CTO hold after this tax withholding?

After the tax withholding, the CTO directly holds 181,410 AEHR common shares. The filing notes this amount includes shares subject to unvested restricted stock units, reflecting both vested and certain unvested equity awards.

What price per share was used for the AEHR tax-withholding shares?

The 102 withheld AEHR shares are reported at $88.48 per share. This price is used in the Form 4 to value the tax-withholding disposition associated with the vesting of restricted stock units granted to the CTO.

How significant is the AEHR CTO’s 102-share tax withholding versus his total holdings?

The 102 withheld shares represent a small portion of the CTO’s 181,410-share direct position. This indicates the transaction is routine tax-related activity tied to equity compensation rather than a large discretionary reduction in his ownership.
