SPORCK ALISTAIR N 4

What Happened

• Alistair N. Sporck, Vice President, Contractor Business Unit at AEHR Test Systems (AEHR), acquired 1,963 shares on 2026-04-01 at $6.67 per share for a total of $13,098. On 2026-04-02, 298 shares were reported as disposed at $44.32 (value $13,207) but those 298 shares were withheld to satisfy tax-withholding obligations upon the vesting of restricted stock units (RSUs) and do not represent an open-market sale.

Key Details

• Transactions:
  • 2026-04-01 — Other acquisition (Code J): 1,963 shares at $6.67 each; total $13,098.
  • 2026-04-02 — Tax/payment withholding (Code F): 298 shares at $44.32 each; value $13,207 (shares withheld to cover taxes on RSU vesting).
• Footnotes of note:
  • F1: Withheld shares were used to satisfy tax withholding on RSU vesting — not a sale by the reporting person.
  • F2: Reported amounts include shares subject to unvested RSUs.
  • F3: The purchase was made through the company’s Amended and Restated 2006 Employee Stock Purchase Plan (ESPP), a “tax‑conditioned” plan under IRC §423; ESPP purchases are exempt from Section 16 short-swing liability.
• Shares owned after transaction: Not specified in this Form 4.
• Filing timeliness: Form 4 filed 2026-04-02 reporting transactions on 2026-04-01 and 2026-04-02 — appears to be filed timely.

Context

• The 1,963-share transaction is a purchase (ESPP), which is generally viewed as a routine employee stock-plan buy rather than an active open-market investment decision. The 298-share "disposition" was a tax withholding mechanism upon RSU vesting (a common administrative action), not a market sale.
