  • The decline extends a pullback after an 11-session rally that had taken the stock to a 52-week high near $147.
  • The move appears to reflect profit-taking rather than new negative news, following a $22 million follow-on order from the company's lead AI processor customer and record fourth-quarter bookings of $60.7 million.

Shares Pull Back After Extended AI-Driven Rally

Aehr Test Systems shares closed sharply lower, down about 12.41 percent at $107.96, extending a pullback after an 11-session rally that had taken the stock to a 52-week high near $147. The decline appears to reflect profit-taking rather than any new negative development, coming even as the company reported a $22 million follow-on order from its lead AI processor customer and record fourth-quarter bookings of $60.7 million.

Aehr Test Systems (NASDAQ:AEHR) is a Fremont, California based provider of wafer-level and package-level test and burn-in solutions for the semiconductor industry, with core product families that help manufacturers test and stabilize devices including silicon carbide power semiconductors, gallium nitride chips, and processors used in AI, electric vehicle, and Data Center applications.

Backlog and Guidance Remain Supportive Despite Pullback

The company reported approximately $100.6 million in Backlog and issued fiscal 2027 Revenue guidance of $130 million to $150 million, underlying fundamentals that remain supportive even as the stock's steep run-up had left it trading at an extremely elevated valuation. Today's pullback comes amid a broader semiconductor selloff tied to surging long-term Treasury yields, which has pressured profit-taking across AI hardware names more broadly.

Insider Selling Adds to Investor Caution

Recent insider selling by the CEO, chief operating officer, and other executives has added to investor caution, even as analyst sentiment remains broadly bullish, with one research platform maintaining a $175 price target. The scale of today's decline, following such a rapid prior run-up, suggests the stock may remain volatile as the market continues to reassess an appropriate valuation for its AI-driven growth story.

Where Things Stand

Aehr Test Systems shares closed down about 12.41 percent at $107.96, giving back part of an 11-session rally amid broader semiconductor sector profit-taking. These are the verified facts as reported. Whether the stock stabilizes may depend on how the market reconciles its still-elevated valuation against the company's growing AI-related order backlog.
