Every chip can look great in the lab. But the lab is controlled, clean, and predictable. The real world is not. The real world is hot, unstable, messy, and unforgiving.

That is where Aehr Test Systems comes in.

Aehr builds advanced testing systems that stress-test chips before they are used in real products. These chips end up inside electric vehicles, fast chargers, solar inverters, industrial machines, data centers, and other high-voltage power systems where reliability matters. In these markets, a failed chip is not just a small technical issue. It can lead to costly repairs, downtime, safety risks, and damaged customer trust.

The company’s core focus is burn-in testing. Burn-in testing means forcing chips to operate under difficult conditions before they are shipped to customers. Aehr’s systems expose chips to heat, voltage, long operating times, and other stress factors. The goal is simple: find the weak chips before they fail in the real world.

This is especially important for silicon carbide chips, also called SiC chips. Silicon carbide is becoming one of the most important materials in modern power electronics because it can handle high voltage, high temperature, and high power more efficiently than traditional silicon chips. That makes SiC critical for electric vehicles, charging infrastructure, solar energy, industrial power systems, and other applications where efficiency and reliability are essential.

Aehr reported more than $37M in quarterly bookings in fiscal Q3 2026, driven by AI, data center infrastructure, and silicon photonics demand. Revenue was still unimpressive, but the backlog shows that demand is high. So, it might not be the strongest on the fundamentals but the technical setup looks good for short-term opportunity.

The Setup:

• Winning a major new silicon photonics customer

• The demand for AI and its supply chain is growing exponentially

• Breaking out of an ascending triangle
