Aehr Test Systems (AEHR) shares took a hit in Thursday's extended trading session after the company's second-quarter earnings report came up short on the top line.

The Numbers: The semiconductor test equipment maker reported a quarterly loss of four cents per share, meeting analyst expectations on that front. But revenue told a different story, coming in at $9.88 million versus the Street's call for $11.59 million—a miss of about 15%. That's also down from the $13.45 million the company brought in during the same quarter last year.

Bookings for the quarter totaled $6.2 million. The company's backlog as of November 28, 2025 stood at $11.8 million, with effective backlog (including bookings received after that date) reaching $18.3 million.

"While second quarter revenue was softer than anticipated, we made significant progress in both wafer-level burn-in (WLBI) and packaged-part burn-in (PPBI) segments and are very excited about our prospects moving forward," said CEO Gayn Erickson.

Stock Movement: According to market data, Aehr Test Systems stock dropped 7.75% to $20.94 in after-hours trading Thursday.
