Aehr Test Systems shifts focus to AI infrastructure, posting record $60.7M Q4 bookings and strong growth outlook.

Aehr Test Systems has transitioned from supplying silicon carbide for electric vehicles to focusing on AI infrastructure, with AI processors and silicon photonics now making up 91% of its revenue. In the fourth quarter, the company achieved record bookings of $60.7 million, boosting its backlog to about $100.6 million and supporting projected revenue growth of 160%-200% by fiscal year 2027. The growing importance of wafer-level burn-in testing aligns with industry trends like TSMC's CoWoS capacity expansion and ASML's EUV backlog, indicating sustained demand for Aehr's testing solutions. Current guidance excludes significant memory revenue and major AI processor opportunities, suggesting further growth potential ahead.
