[Form 4] Aehr Test Systems Insider Trading Activity

Rhea-AI Filing Summary

Aehr Test Systems (AEHR) – Form 4 insider filing

On 07/11/2025, President & CEO Gayn Erickson reported an automatic share withholding related to the vesting of restricted stock units (Transaction Code F). A total of 1,052 common shares were surrendered at $14.11 solely to cover tax-withholding obligations; no open-market sale occurred.

Following the transaction, Erickson’s ownership stands at 277,029 shares held directly and 291,088 shares held indirectly through a trust. The filing reiterates that the reported figure includes unvested RSUs and restricted shares.

Because the event is tax-related and involves a small fraction of the executive’s total holdings, it is viewed as neutral from a market-impact perspective.

Insights

Financial Analyst

TL;DR Small, tax-related share withholding by CEO; no open-market sale; ownership remains large—neutral impact.

The Form 4 discloses an F-code transaction, which indicates shares withheld by the issuer to satisfy taxes on vested equity awards. Only 1,052 shares (<1% of Mr. Erickson’s combined holdings) were involved at $14.11. He still controls roughly 568k shares (direct + trust), preserving strong alignment with shareholders. Because the transaction neither adds nor removes shares from the public float and does not represent a discretionary sale, I deem the filing routine and not materially price-sensitive.
