Can AEHR's Diversification Strengthen Its Growth Outlook?

Aehr Test Systems has dramatically diversified its revenue streams, with AI processors and silicon photonics now driving nearly 95% of fiscal 2026 revenues, compared to over 95% EV-related SiC exposure two years prior. The company secured a $22 million follow-on order for AI processor systems in August and maintains a $100.6 million backlog with a $130-$150 million fiscal 2027 revenue outlook, though it faces intense competition from larger rivals Teradyne and FormFactor in the semiconductor test equipment market.
