• The latest order represents the third FOX-XP system sale in 2026, after a $14 million deal in February and an additional purchase in March.
• The purchase comes from the company’s primary silicon photonics client, which has already deployed and activated its initial system.

Shares of Aehr Test Systems (AEHR) surged more than 13% Thursday following the semiconductor equipment maker’s announcement of a fresh production order from its primary silicon photonics client. By midday trading, the stock maintained gains of approximately 11.75%.

The new purchase involves a fully automated FOX-XP wafer-level burn-in (WLBI) platform, combined with the FOX WaferPak AutoAligner system. This integrated setup enables simultaneous testing of up to nine 300mm wafers without any manual intervention.

The client is deploying this equipment to facilitate mass production of silicon photonics components designed for AI optical interconnects and hyperscale data center operations.

This represents a repeat purchase. The same client received its initial FOX-XP production unit during Aehr’s fiscal 2026, and the company has verified the system has been successfully integrated and is currently operational.

Chief Executive Gayn Erickson characterized the deal as “another important milestone” in the ongoing partnership with this customer, expressing satisfaction at “receiving this additional follow-on production order early in our new fiscal year.”

The deal also constitutes the third FOX-XP WLBI system purchase Aehr has secured in 2026. The initial order arrived in February with a $14 million valuation, while a subsequent order followed in March.

Order Volume Exceeds Projections

In April, Aehr disclosed that it secured over $92 million in orders throughout the latter half of fiscal 2026. This figure substantially exceeded the company’s prior guidance range of $60 million to $80 million.

According to analysts monitored by Fiscal.ai, projections show Aehr’s yearly revenue climbing from $49.8 million in 2026 to $85.1 million in 2027.

Broader market activity remained subdued Thursday. The Nasdaq increased 0.4% while the S&P 500 rose 0.2%. Industry competitors including Teradyne and FormFactor released no similar announcements, clearly indicating the AEHR rally stemmed exclusively from its order news.

Earnings Release Imminent

The strategic timing of Thursday’s disclosure carries additional significance. Aehr plans to publish its fiscal 2026 fourth-quarter and full-year financial results on July 14 — merely five days away.

This close timing probably encouraged investors to act swiftly. A verified production order from a major customer, announced just before earnings, represents a favorable indicator heading into the financial release.

Aehr specializes in manufacturing test and burn-in equipment for semiconductors spanning power devices, sensors, memory modules, processors, and silicon photonics elements. The FOX-XP system has served as the company’s primary revenue catalyst during the ongoing AI infrastructure expansion.

The company noted its customer is engineering technology designed to enhance data transmission speeds while reducing power consumption in AI processors and high-performance computing architectures.

As of Thursday morning, AEHR shares had appreciated over 13% during the session, with the third FOX-XP order of 2026 and the upcoming July 14 fiscal year earnings announcement both now clearly influencing investor sentiment.
