About Aehr Test Systems
About Aehr Test Systems
Aehr Test Systems generated roughly $50.0 million of net revenue in fiscal 2026, split between $31.5 million from full wafer contact products and $18.5 million from package level test and burn-in, versus about $59.0 million in fiscal 2025. Backlog stood at $80.6 million at May 29, 2026, compared with $15.2 million a year earlier. The Fremont, California company, incorporated in 1977, sells test and burn-in systems for AI processors, silicon carbide and gallium nitride power devices, and silicon photonics.
Aehr sells to semiconductor manufacturers, contract assemblers, electronics manufacturers and burn-in and test service companies. The FOX-XP platform can test and burn-in up to 18 wafers at a time, and each system relies on WaferPak Contactors and DiePak Carriers that are custom designed for each device type with a typical lifetime of two to seven years, so multiple sets could be purchased over the life of one system. Package level revenue comes from the Sonoma, Tahoe and Echo platforms acquired in fiscal 2025; the Sonoma line targets AI accelerators and GPUs drawing as much as 1600 or more watts. The company assembles products from components made by others, including environmental chambers, power supplies and printed circuit assemblies. The filing names larger systems manufacturers, independent test labs that build their own burn-in systems, and captive burn-in suppliers to large IC makers in Asia as competitors. Sales and service operations sit in the United States, Germany, Japan, the Philippines and Taiwan, with dedicated resources in China and South Korea.

Customer concentration is the sharpest lens on the filing. Sales to the five largest customers made up approximately 70% of net sales in fiscal 2026, after 77% in fiscal 2025 and 93% in fiscal 2024. In fiscal 2026 three customers accounted for approximately 26%, 14% and 11%, while in fiscal 2024 two customers accounted for approximately 67% and 17%. Most purchase orders can be cancelled or rescheduled with limited penalties, so the $80.6 million backlog may not translate into revenue in a given period, and the loss or deferral of a few high-value system sales could weigh on quarterly results.
