On July 15, Aehr Test Systems rose 30.88% in pre-market trading, trading at $94.53/share, with turnover of $471,500.

The surge was driven by the company's Q4 earnings report, which significantly exceeded market expectations. Adjusted EPS came in at $0.11, far surpassing the consensus estimate of -$0.01, while revenue of $18.835 million also beat the $18.686 million estimate. The earnings surprise was further amplified by order momentum — the company received a follow-on production order in June for a fully automated FOX-XP wafer-level burn-in system from a major data center optical transceiver supplier, with delivery expected within six months. Management disclosed that a top-tier AI chip customer has successfully completed over six months of benchmark testing, strengthening expectations for subsequent large-scale orders.

Within the Semiconductor Equipment sector, the overall sector showed strength. Among individual stocks, ASML Holding NV up 5.65%, Lam Research up 4.45%, KLA-Tencor up 4.37%, Applied Materials up 4.08%, Teradyne up 3.62%.
