What this transaction means for investors
Director Howard Slayen is yet another Aehr Test Systems insider selling after the stock ran up nearly 500% in the past 12 months. His August 4 disposition was a discretionary transaction, which makes sense given the significant share price increase.
The sale reduced holdings by a substantial 12%. That said, Slayen retained over 146,000 shares post-transaction, some of which are unvested RSUs, limiting his ability to dispose of more stock until they vest. This helps to ensure his continued alignment with shareholder interests.
Aehr Test Systems stock rose thanks to a strong earnings report for its fiscal fourth quarter ended May 29. Revenue reached $18.8 million, up from $14.1 million in the prior year.
In addition, the company announced record fiscal Q4 bookings of $60.7 million, and forecasted sales between $130 million and $150 million in its 2027 fiscal year. That’s a massive increase from the $50 million made in fiscal 2026, and sign customer demand is accelerating amid growth in the artificial intelligence sector.
Slayen is a long-time Board member, having served with Aehr Test Systems since 2008.
