The stock of Aehr Test Systems (NASDAQ: AEHR ) has gotten a lot of attention after rallying nearly 681% over the past year. A little more than half of that gain came in 2026 alone. Sounds like a stock that needs a closer look, doesn’t it?
Let’s take a look at what it does before committing to buying shares. Here’s an overview of Aehr Test Systems’ involvement with the artificial intelligence (AI) boom and whether it presents a good buying opportunity.
Missed Nvidia in 2009? This Rare Signal Lights Up Again. In 2009, a “Double Down” signal lit up a little-known chip maker called Nvidia. For the first time in years, that “Believe It All” signal is shining on a company 1/100 the size of Nvidia. Continue »
What does Aehr Test Systems do?
AI chipmakers love it Nvidia again Broadcom sell millions of chips a year, but not all of them really work; a small percentage fail soon after use. Technology companies accept it as a cost of doing business, but if the failure rate was too high, it would make hyperscalers more cautious.
Companies like Aehr Test Systems are tackling this problem by stress testing microchip bulk samples under extreme conditions to catch defects early. This reduces the number of useless chips leaving the factories.
The company has been testing its technology by partnering with hyperscalers for years and has finally started making lucrative deals. It reported more than $37 million in quarterly bookings for the third fiscal quarter of 2026 (ended Feb. 27, 2026) and said it expects an “imminent production order” from its top hyperscale customer.
Not even two weeks later, that big booking came. A record $41 million in production from that hyperscale customer led to second-half bookings of more than $92 million. Aehr Test Systems also announced a “strong pipeline of existing forecasted customer orders.”
Earlier this month, management announced another major win: a follow-on manufacturing order from what it described as a “global leader in network products and solutions,” a major supplier to the optical data transceiver market.
Can Aehr Test Systems’ rally continue?
Aehr Test Systems is getting more attention for its stress testing technology, and revenue growth could be very fast. The $92 million in second-half bookings compares favorably with $10.3 million in third-quarter revenue.
A $41 million production order from a lead hyperscaler shows how quickly backlog and overall revenue can grow. Each order of that level will have a seismic impact on revenue, and executives are positioning themselves to attract more hyperscalers.
