Aehr Test Systems Q4 2026 Earnings Recap

Investor enthusiasm propelled Aehr Test Systems’ shares up 29.1% following earnings, driven by strong demand growth in AI and data center markets along with a substantial increase in backlog that signals robust revenue acceleration ahead.

Key Takeaways

• Fiscal 26 capped by record quarterly bookings and a record backlog fueling confidence in a 2.6x to 3x revenue increase projected for fiscal 27 ($130M to $150M).
• Non-GAAP pretax margin guidance raised to between 18% and 22%, reflecting anticipated operational leverage with scaling demand.
• Revenue diversification successful: 71% of fiscal 26 revenue came from wafer-level burn-in and screening for AI accelerators, CPUs, and network processors; 20% from optical device test for data center infrastructure.
• Major AI wafer-level burn-in customers accelerating orders and moving production to Aehr’s WaferPak systems, eliminating the need for less efficient package-level testing and driving higher unit demand.
• Promising near-term pilot production opportunities with top-tier AI processor suppliers for multiple device lines, indicating a stepping stone to sizable high-volume production revenue streams.
