Amended and Restated 2006 Employee Stock Purchase Plan financial

"These shares have been purchased through the Company's Amended and Restated 2006 Employee Stock Purchase Plan"

tax-conditioned plan financial

"a "tax-conditioned plan" per Internal Revenue Code Section 423"

restricted stock units financial

"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.

Section 16 regulatory

"This purchase is exempt from Section 16 of the Securities Exchange Act of 1934"

Section 16 is a U.S. securities law rule that governs the trading and disclosure obligations of company insiders — typically officers, directors and large shareholders — to promote transparency and deter unfair profit-taking. It requires insiders to publicly report their stock trades and allows companies or the issuer to reclaim quick, short-term profits from certain insider trades, like a scoreboard and a refund policy that help investors see and limit possible insider advantage.

FAQ

AI-generated questions and answers. How Rhea-AI works. Not financial advice.

What insider transactions did AEHR executive Vernon Rogers report?

Vernon Rogers reported two routine equity events: acquiring 1,558 AEHR common shares through the employee stock purchase plan, and 336 shares withheld to cover taxes on restricted stock unit vesting. The filing emphasizes the tax withholding is not a sale by Rogers.

How many AEHR shares does Vernon Rogers hold after these Form 4 transactions?

After the reported transactions, Vernon Rogers directly holds 178,428 AEHR common shares. The disclosure notes this amount also includes shares subject to unvested restricted stock units, meaning part of his position remains subject to future vesting conditions under the company’s equity compensation arrangements.

What is the nature of the AEHR employee stock purchase plan used in this filing?

The shares were acquired under Aehr Test Systems’ Amended and Restated 2006 Employee Stock Purchase Plan, described as a “tax-conditioned plan” under Internal Revenue Code Section 423. This structure provides favorable tax treatment and renders those purchases exempt from Section 16 short-swing profit liability rules.

Does the AEHR Form 4 show Vernon Rogers selling any shares on the market?

No open-market sales are reported. The 336 shares noted with code F were withheld solely to satisfy tax obligations upon vesting of restricted stock units. The filing explicitly states this tax withholding “does not represent a sale” by Vernon Rogers in the company’s common stock.

What do the tax withholding shares in the AEHR Form 4 represent?

The 336 AEHR shares reported with transaction code F were withheld to cover income tax obligations when restricted stock units vested. This is an administrative method for paying taxes in shares rather than cash and is not considered an open-market sale by the reporting person.

How large were the equity plan transactions for AEHR relative to Vernon Rogers’ holdings?

Rogers acquired 1,558 shares via the employee stock purchase plan and had 336 shares withheld for taxes, compared with 178,428 shares held afterward. This indicates the transactions are small, routine adjustments within a substantially larger ongoing equity position in Aehr Test Systems.
