Aehr Test Systems Plunges 20.44% on Revenue Miss

Aehr Test Systems experienced a significant drop of 20.44% in pre-market trading on July 9, 2025, following the release of its fiscal 2025 Q4 results, which failed to meet revenue expectations.

Aehr Test Systems reported fourth-quarter revenue of $14.09 million, falling short of analyst estimates of $14.82 million. This revenue shortfall of 4.73% was a notable miss, contributing to the stock's decline. The company highlighted its expansion into new markets, including AI processors and gallium nitride (GaN) power semiconductors, as part of its strategic initiatives to diversify its customer base and enhance its product portfolio.

During the earnings call, Gayn Erickson, President and CEO of Aehr Test Systems, emphasized the transformative nature of fiscal 2025. The company successfully launched its first production wafer level burn-in system for AI processors, attracting strong interest from leading processor companies. This breakthrough is expected to unlock substantial growth opportunities, particularly in the high-volume production of AI processors.

Despite the revenue miss, Aehr Test Systems remains optimistic about its future prospects. The company is moving forward with evaluations for wafer level testing with additional AI companies and believes it can capture a meaningful share of the total production burn-in market for AI processors with its FOX WLBI systems and proprietary WaferPak Contactors.
