AI Testing Firm Aehr Soars 300% as Chip Reliability Demand Grows

Aehr Test Systems, a previously overlooked player in the semiconductor space, has surged over 300% since April 2025. The stock rebounded from $6.27 to $26.43 per share after pivoting from electric vehicle exposure to AI infrastructure support.

The company's wafer-level burn-in and test systems have become critical for hyperscalers building next-gen data centers. With chip Stacks now reaching hundreds of millions of units, Aehr's reliability solutions prevent catastrophic failure rates that could cost operators billions in downtime and replacements.

While the stock remains below its 2024 peak of $50, the AI-driven demand for its testing technology suggests continued upside. The market appears to be slowly recognizing Aehr's pivotal role in ensuring the integrity of advanced chip architectures powering artificial intelligence workloads.
