"Aehr Test Systems supplies wafer-level and package-level burn-in systems that test semiconductors under extreme conditions before they ship to hyperscale data centers. Its stock traded in a narrow range through most of 2025, closing the year at $20.19, ranging between $6.78 and $33.63 per share."
"In January, management reinstated full-year guidance on the back of 'improved visibility for AI processor and data center semiconductor test.' By March, the stock had already doubled its 2025 close, driven by steady order flow in silicon photonics and AI custom silicon."
"On March 31, Aehr announced an initial order from a global networking leader that supplies hyperscale data centers. The customer bought multiple FOX-XP wafer-level burn-in systems configured to test nine wafers in parallel, plus FOX-NP systems."
Aehr Test Systems specializes in semiconductor testing equipment, particularly for AI and data centers. After a stagnant 2025, the company saw a significant stock increase in early 2026 due to improved visibility in orders. The stock doubled by March following the reinstatement of full-year guidance. A pivotal order from a major networking company on March 31 further propelled the stock, indicating strong demand for its wafer-level burn-in systems. Investors focusing on backlog rather than quarterly revenue recognized this shift early.
