Aehr Test Systems (AEHR) stock climbed more than 13% on Thursday after the company announced a new production order from its lead silicon photonics customer. The stock was trading up around 11.75% by midday.

Aehr Test Systems, AEHR

The order is for a fully automated FOX-XP wafer-level burn-in (WLBI) system, paired with the FOX WaferPak AutoAligner. Together, the two systems can test up to nine 300mm wafers at the same time with no manual handling required.

The customer is using the equipment to support high-volume production of silicon photonics devices for AI optical interconnects and hyperscale data center infrastructure.

This is a follow-on order. The same customer already took delivery of its first FOX-XP production system during fiscal 2026, and Aehr confirmed it was successfully installed and is now in production.

CEO Gayn Erickson called it “another important milestone” in the company’s long-term relationship with the customer, and said the company was “very pleased to receive this additional follow-on production order early in our new fiscal year.”

It also marks the third FOX-XP WLBI order Aehr has received in 2026. The first came in February, worth $14 million, followed by another in March.

Orders Well Ahead of Forecasts

In April, Aehr reported it booked more than $92 million in orders during the second half of fiscal 2026. That came in well above its own earlier forecast range of $60 million to $80 million.

Analysts tracked by Fiscal.ai expect Aehr’s annual revenue to grow from $49.8 million in 2026 to $85.1 million in 2027.

The broader market was relatively quiet on Thursday. The Nasdaq edged up 0.4% and the S&P 500 gained 0.2%. Peers like Teradyne and FormFactor had no comparable news, making clear the AEHR move was driven entirely by its own order announcement.

Earnings Just Days Away

The timing of Thursday’s announcement adds another layer. Aehr is scheduled to release its fiscal 2026 fourth-quarter and full-year earnings on July 14 — just five days away.

That proximity likely gave investors extra reason to move quickly. A confirmed production order from a key customer, ahead of earnings, is a positive signal heading into the report.

Aehr makes test and burn-in systems for semiconductors including power chips, sensors, memory chips, processors, and silicon photonics components. The FOX-XP platform has been its main growth driver in the current AI infrastructure cycle.

The company said its customer is developing technology aimed at improving data transfer speeds and cutting power use in AI processors and high-performance computing systems.

As of Thursday morning, AEHR had gained more than 13% on the day, with the third FOX-XP order of 2026 and a fiscal year earnings release on July 14 both now firmly in view.
