AEHR stock climbed 46% in February despite the broader tech sector pulling back. The gains came after they announced multiple contract wins for AI chip testing systems, including a $14M order from their lead customer on Feb 26. They also added a new order on March 3 for optical architecture testing. Management reinstated guidance for the fiscal year ending May 30, expecting sales between $25 million and $30 million. The stock has doubled year-to-date and is trading at about 26 times sales. It looks like demand for their burn-in systems is picking up alongside AI data center growth.
