On July 30, Aehr Test rose 8.06% in pre-market trading, trading at 70.0 USD/share, with turnover of $1.99 million. The rebound comes as the broader semiconductor equipment sector rallied strongly, with Lam Research up 12.93%, Applied Materials up 8.26%, KLA up 6.56%, Teradyne up 6.12%, and ASML up 4.49%.

The stock had declined sharply in recent sessions after the company filed a mixed shelf registration statement with the SEC on Monday evening, covering potential future sales of common stock, preferred stock, debt securities, depositary shares, warrants, subscription rights, and units. The filing triggered dilution concerns and pushed shares down over 15% from recent highs.

Fundamental support remains intact following the company's fiscal Q4 earnings report in mid-July, which showed record quarterly orders driven by AI data center demand. The company's business has transformed significantly, with AI accelerator, CPU, and network processor wafer-level burn-in testing now contributing 71% of annual revenue, up from under 5% two years ago.
