Gayn Erickson, President and CEO of Aehr Test Systems, commented on the improving customer and market conditions:

“Our bookings of $8.0 million during the third quarter is our highest bookings quarter in over a year and includes two customer orders for our FOX-XPTM test cells. One of these orders is from an existing customer for a partially populated FOX-XP multi-wafer test and burn-in system and multiple WaferPakTM Contactors to begin volume production of their high-performance silicon photonics devices. This customer is a major supplier of fiber optic transceivers in the Data Center Interconnect (DCI) market and is transitioning from Aehr’s FOX-NP™ system for initial production burn-in and stabilization to using Aehr’s production FOX-XP system to meet their high-volume production forecast. The other FOX-XP test cell order from a new customer totaled $4.3 million and included a single FOX-XP test system, a set of FOX DiePak Carriers®, and a fully automated DiePak loader/unloader. This order was for an initial test cell for test and burn-in of sensors to a major mobile device manufacturer.

“During our fiscal third quarter we began to see signs of recovery from several customer production ramp delays and push outs of forecasted orders that we experienced related to COVID-19. Our improved bookings and revenue in the quarter reflect significant increased activity with both current and new customer engagements as business conditions began to improve. This increased business activity includes reengagement with existing customers as they focus on increasing their production capacity, particularly as the data center and 5G infrastructure-related silicon photonics optical transceiver market is starting to recover. Multiple customers have completed facility upgrades for expected FOX system deliveries in the near future. In addition, we are seeing new customer investigations and evaluations for wafer level burn-in with multiple silicon carbide companies and over a dozen silicon photonics and transceiver laser stabilization applications, and also evaluations for both wafer level burn-in and package part burn-in for automotive devices.

“We are also seeing increased orders for our proprietary WaferPak consumables from existing customers in the silicon carbide and silicon photonics segments for their installed base of FOX multi-wafer test systems. Towards the end of our fiscal third quarter and into our fourth quarter so far, we have received multiple orders for new designs and added capacity for volume production test of silicon carbide power semiconductors for electric vehicles and electric vehicle chargers, as well as silicon photonics devices for data center and 5G infrastructure fiber optic transceivers. We are forecasting additional orders for our WaferPak and DiePak consumables during the remainder of the current fiscal year from our installed base of customers.

“With our increasing customer visibility, including facility improvements that customers have made to install our tools on their test floors, we continue to expect orders from the customers that told us they would ramp in the first half of our fiscal year. We expect to end our fiscal year with a strong year-over-year growth in our bookings. Unfortunately, the timing of some orders was delayed causing us to come in short of our revenue expectations for this fiscal year. Most importantly, we expect this booking momentum will continue, which will drive revenue growth in the next fiscal year.

“Looking forward this quarter and into our fiscal 2022 that begins June 1, we feel our outlook is very promising, with forecasts from current customers to ramp in silicon carbide for electric vehicles and electric vehicle chargers; silicon photonics for data center and 5G infrastructure; 2D, 3D and other mobile sensors; and flash memory devices. We also expect to announce new customer bookings and shipments, particularly in silicon carbide and other automotive devices, during this calendar year.”

Fiscal Q4 2021 Financial Guidance:

For the fiscal fourth quarter ending May 31, 2021, Aehr expects revenue to be at least $7.0 million, a 33% sequential increase from the third quarter, and to be profitable for the fiscal fourth quarter.
