[Form 4] Aehr Test Systems Insider Trading Activity

Rhea-AI Filing Summary

Form 4 overview: On 07/02/2025, Alistair N. Sporck, Vice-President of the Contractor Business Unit at Aehr Test Systems (AEHR), reported several equity transactions.

• Restricted Stock Units granted: 9,253 RSUs with quarterly vesting over four years (1/16 per quarter) and 2,276 RSUs with 25% immediate vesting and the balance vesting quarterly over three years. Both grants were recorded at a cost basis of $0.
• Tax-withholding transaction: 305 shares were automatically withheld at $15.13 to cover taxes on vested RSUs; this is classified as a disposition code “F” and does not represent an open-market sale.
• Post-transaction ownership: Sporck now directly owns 34,120 common shares and indirectly controls 3,993 shares through a trust.
• The filing notes an additional 936 shares received on 04/25/2025 from the termination of the company’s ESOP, included in the total.

No derivative securities were reported. The transactions reflect routine executive compensation and tax-withholding activity, with no cash proceeds to the insider and no change to the company’s share count.

Insights

Financial Analyst

TL;DR: Routine RSU grants increase insider holdings; immaterial to AEHR valuation.

The Form 4 details standard executive compensation—11,529 RSUs granted to VP Alistair Sporck and 305 shares withheld for taxes. Net ownership rises to 34,120 shares (direct) plus 3,993 indirect. No open-market buying or selling occurred, so supply-demand dynamics are unaffected. Given AEHR’s 28 million share float, the incremental insider ownership (<0.1%) is immaterial to earnings, cash flow, or float. Investors should view the filing as neutral housekeeping rather than a leading indicator of future performance.

Corporate Governance Specialist

TL;DR: Filing complies with Section 16; no red flags or unusual terms.

The award structures—quarterly vesting over three to four years—align with common retention practices, promoting long-term alignment without accelerated change-of-control clauses. The tax-withholding disposition (code F) is routine. Signature by Attorney-in-Fact Chris Siu and timely filing (T+2) satisfy governance best practices. Overall, the disclosure is procedurally sound and does not alter the risk profile.
