Aehr Test Systems Q4 Earnings Call Highlights

Aehr Test Systems entered fiscal 2027 with a record backlog and raised revenue guidance to $130 million to $150 million, implying roughly 160% to 200% year-over-year growth. Management also expects non-GAAP pretax net income to reach 18% to 22% of revenue.

Demand was driven by AI processors, silicon photonics, and data center infrastructure, with fiscal Q4 bookings jumping to $60.7 million from $11.1 million a year ago and backlog rising to a record $80.6 million. The company said AI and silicon photonics burn-in made up more than 80% of Q4 revenue.

The business has diversified away from electric-vehicle silicon carbide: nearly 95% of fiscal 2026 revenue came from non-EV SiC markets, while AI and data center customers became the biggest growth engines. Aehr also highlighted expanding opportunities in wafer-level and package-level burn-in, plus capacity additions to support future demand.

Aehr Test Systems NASDAQ: AEHR said it entered fiscal 2027 with record backlog and expects revenue to more than double, citing accelerating demand tied to artificial intelligence processors, silicon photonics and data center infrastructure. President and Chief Executive Officer Gayn Erickson said the company’s fiscal fourth quarter “exceeded consensus street expectations” and capped a year in which Aehr broadened its business beyond its earlier concentration in silicon carbide devices for electric vehicles.
