Aehr Test Systems stock fell 6.53% to $120.79 in the session, reversing earlier gains after a strong open. The stock opened at $128.47, a 0.6% gap down from the prior close, but quickly lost momentum amid selling pressure and a sharp intraday low of $116.50. The move follows a $22 million follow-on order for wafer-level burn-in systems and a recent surge in investor interest, but appears to reflect profit-taking and investor caution after a volatile week.

What Happened

Aehr Test Systems announced a $22 million follow-on production order for its FOX-XP wafer-level burn-in systems, which are used by AI processor manufacturers. Executives highlighted strong demand for wafer- and package-level testing solutions during the Needham Virtual Semiconductor and SemiCap 1x1 Conference on August 19. The order is expected to be fulfilled over six months and shipped to Taiwan. The company also confirmed participation in expanding AI testing capabilities. Despite these developments, the stock declined sharply in the afternoon session.

What The Data Shows

The stock opened with a modest gap down and reached a high of $128.84 before declining sharply. Volume was 0.7 million shares, or 0.2 times the 3-month average, suggesting limited liquidity in the fast-moving session. The stock is currently trading within its 52-week range of $16.38 to $133.35 but remains well off its recent high. The company has a market cap of $3.3 billion and remains unprofitable with a trailing twelve-month net margin of -14.3% and a beta of 3.09. Recent insider transactions include a $5.1 million total in sales over the last 90 days, with no insider buys reported.

What To Watch

Aehr Test Systems has no scheduled earnings date in the immediate future. Investors should monitor coverage breadth and the company’s ability to execute on the $22 million order, as well as any further insider activity or changes in market sentiment.
