Can AEHR's Diversification Strengthen Its Growth Outlook?

AEHR has pivoted its revenue base away from electric vehicle silicon carbide testing toward AI and optical networking, with AI processors and silicon photonics now representing nearly 95% of fiscal 2026 revenues—a sharp reversal from over 95% EV-related exposure two years earlier.

The company reported a $22 million follow-on order for AI processor test systems in August and holds a $100.6 million backlog. Management projects fiscal 2027 revenue between $130 million and $150 million as it scales capacity for the data center buildout.

AEHR faces headwinds from larger incumbents TER and FORM, both of which command broader product portfolios and deeper customer relationships in the semiconductor test equipment sector. The stock remains leveraged to AI infrastructure spending but vulnerable to delays in fab capacity additions or share losses to better-capitalized competitors.

The transition reduces concentration risk tied to the slower-than-expected EV ramp, but AEHR now competes for test socket share in a market dominated by companies with significantly larger R&D budgets and installed bases.
