Thesis
Aehr Test Systems is a small-cap semicap player specializing in wafer-level burn-in and stress testing — a niche where AI processors and silicon photonics increasingly require pre-shipment screening to catch field failures at the wafer rather than packaged-part stage. The company built its franchise on SiC power devices for EVs and has been pivoting capacity toward AI compute and photonics customers, with record orders in late 2025.
The investment case is leverage to AI-chip yield discipline at hyperscalers and a credible second leg in photonics test. Risks are real: revenue is concentrated across a handful of customers, the SiC business has been volatile with EV demand, and a single program win or loss can swing a quarter materially. This is a small-cap, high-beta semicap exposure rather than a compounder.
Catalysts
- AI processor and silicon photonics design wins
- SiC test order recovery
- Backlog and book-to-bill trends each quarter
- Capacity utilization at customer fabs driving WaferPak refresh
