Gayn Erickson, President and CEO of Aehr Test Systems, commented:

“Our fiscal first quarter results demonstrate the accelerating demand for our AI semiconductor test and burn-in solutions and our ability to execute against expanding customer production requirements. Revenue increased 200% year over year and 75% sequentially to a record $33.0 million, while bookings of $46.7 million exceeded revenue by over 40%, reflecting continued strong demand for our wafer-level and package-level burn-in solutions.

“Based on our first quarter performance, substantial backlog, and visibility into customer production requirements, we are raising our fiscal 2027 revenue outlook to $150 million, compared with our previous guidance range of $130 million to $150 million. We expect non-GAAP net income of at least 20% of revenue for fiscal year 2027.

“Demand for our FOX™ wafer-level burn-in (WLBI) solutions remains strong. Our lead AI processor WLBI production customer continues to expand capacity, supported by the $22 million follow-on order announced in August 2026. We have also made significant progress with a major supplier of AI accelerators, CPUs, and network processors that successfully completed a benchmark evaluation last quarter. This customer has decided to purchase a fully configured FOX-XP WLBI test cell for installation at one of its key Outsourced Semiconductor Assembly and Test (OSAT) partners in Taiwan, where the system will be evaluated in a high-volume production environment using the same device that was successfully tested in last quarter’s benchmark. Installation is planned for early calendar 2027, with a decision regarding high-volume production anticipated within several months following installation and validation. We believe this customer represents one of the largest potential burn-in system opportunities Aehr has ever pursued, with significant potential across multiple product lines and manufacturing locations.

“Our Sonoma high-power package-level burn-in (PLBI) business is also expanding rapidly. We are currently shipping and installing more than a dozen systems per month to support our lead hyperscale customer’s production ramp for its first AI processor. The same customer’s second AI processor has now successfully completed qualification on Sonoma, and we have received follow-on orders to support initial production sampling and an anticipated production ramp in calendar 2027. Importantly, the customer forecasts that this second processor will ultimately reach higher production volumes than its first. We are also advancing evaluations with additional AI processor suppliers and hyperscale customers, creating opportunities for new production programs.

Gayn Erickson, President and CEO of Aehr Test Systems, commented:

“We are very pleased with our fiscal fourth quarter performance, which exceeded expectations and capped a year of significant bookings and revenue diversification for Aehr. Record quarterly bookings, a very strong backlog, and growing demand across AI processors, silicon photonics, and power semiconductors for our wafer-level and package-level burn-in solutions position us well for significant growth moving forward.

“With strong momentum and a record backlog of over $100 million heading into fiscal year 2027, we have substantial visibility into projected fiscal 2027 revenue of $130 million to $150 million, representing expected year-over-year growth of approximately 160% to 200%. This outlook is based on the information available to us today, including our current backlog and anticipated customer demand. We continue to pursue additional orders from existing and prospective customers.

“In wafer-level burn-in (WLBI), demand from AI-related applications continued to accelerate. Our lead AI production customer is significantly ramping capacity, driving an increase in forecasted capacity needs for our FOX WLBI solutions this year and beyond. They are shifting their burn-in from system-level to all wafer-level for their AI accelerators used for training and inference applications. We are also engaged with additional AI processor suppliers that are evaluating WLBI to improve product reliability and reduce yield loss from production burn-in of their devices later in the manufacturing process.

“We are excited to report that we successfully completed benchmark testing of our WLBI solution with a major supplier of AI accelerators, CPUs, and network processors. The testing was conducted on one of their processors and produced results that exceeded their expectations. This top-tier AI processor supplier has now expressed interest in moving to pilot production test validation for its current high-volume device, for which we completed the benchmark. They indicated that this device is expected to continue ramping and achieve significant volumes over the next year or more. In addition, they recently requested that we evaluate

Gayn Erickson, President and CEO of Aehr Test Systems, commented:

“We are very pleased with the strong momentum in our business across multiple market segments, highlighted by more than $37 million in quarterly bookings and a book-to-bill ratio exceeding 3.5x. Demand continues to accelerate across both WLBI and PLBI as semiconductor devices grow in size, complexity, and power and are increasingly deployed in mission-critical AI, networking, automotive, and industrial applications.

“During the quarter, we continued to make progress in growing the business and expanding our customer base in our WLBI business. For AI processors, we received a production WLBI order from our lead AI processor customer for multiple new fully automated FOX-XP WLBI systems to be used in data center training and inference applications. We have several other companies ranging from suppliers of data center-focused AI accelerator processors to Edge AI processors and CPUs that are providing us with information on their devices and roadmaps and asking about our WLBI capabilities and recommendations for burn-in of their next generation devices. There is significant interest in doing WLBI for devices that are expected to be put in advanced packages such as CoWoS that include other die such as HBM DRAM stacks, other compute AI processors, and photonic or electrical-based transceiver chipsets. Weeding out bad devices before they are packaged together with these other devices is significantly cheaper than the yield loss if these are burned in at packaged level and the entire multi-chip package is thrown away.

“Silicon photonics is a market we see significant opportunity for WLBI. We recently announced a major new customer win with our high-power FOX-XP WLBI system for devices aimed at hyperscale data center optica
