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

“We had a very solid quarter, reflecting strong sequential and year-over-year growth in revenue and net income, both ahead of consensus estimates. Our momentum in silicon carbide wafer level burn-in continues to grow. We see this momentum continuing for the next several years as companies are adding significant capacity in silicon carbide semiconductors to address the incredible forecasted demand, particularly for the electric vehicle and electric vehicle charger markets.

“Forecasts from William Blair estimate that the silicon carbide market for devices in electric vehicles alone, such as traction inverters and on-board chargers, is expected to grow from 119,000 6-inch equivalent silicon carbide wafers for electric vehicles in 2021 to more than 4.1 million 6-inch equivalent wafers in 2030, representing a compound annual growth rate (CAGR) of 48.4%. Total 6-inch equivalent silicon carbide wafers for all current addressable markets are expected to grow to nearly 7 million 6-inch equivalent silicon carbide wafers in 2030.

“We are excited to have added two new customers for silicon carbide test and burn-in during the quarter. The first is a major silicon carbide semiconductor supplier that purchased our FOX-NPTM dual wafer test and burn-in system used for engineering and device qualification during the quarter, and after the quarter closed has since placed their first orders for two of our FOX-XP multi-wafer systems for volume production test and burn-in of their silicon carbide wafers, including the order we announced today. This customer serves several significant markets including the electric vehicle industry and selected our FOX-XP multi-wafer test and burn-in system configured with our new fully integrated and automated WaferPakTM Aligner for high volume hands-free operation. They have indicated to us they plan to order a significant number of FOX-XP systems for volume production of their silicon carbide devices at facilities around the world to meet the rapidly expanding forecasted market demand for silicon carbide devices for electric vehicles and other industrial markets. The second new customer added this quarter is a multibillion-dollar annual revenue global manufacturer of semiconductors who purchased our FOX-NP test and burn-in system for qualification of their silicon carbide devices for multiple markets including electric vehicles. We anticipate that this customer will move to high volume production using our FOX-XP systems after customer qualifications.

“Adding two new customers now provides more optimism about our ability to gain significant market share of the test and burn-in market for silicon carbide devices. These customers expand our penetration beyond our initial lead silicon carbide wafer level burn-in customer that continues to ramp their capacity and use of our FOX-XP multi-wafer test and burn-in systems and WaferPaks. Our lead customer continues to forecast orders for significant numbers of FOX-XP systems and WaferPak Contactors over the next several years.

“In addition to the customers that have now placed initial orders with Aehr for silicon carbide wafer level test and burn-in systems, our ongoing benchmarks and evaluations with multiple prospects made great progress during the quarter. These include significant market leaders in silicon carbide as well as several companies entering the silicon carbide power semiconductor space. We expect several of these companies to place their initial orders with us before the end of this fiscal year ending May 31, 2023. We also continue to see very positive responses from our discussions with a number of new potential customers in silicon carbide this quarter and have also begun detailed discussions with gallium nitride semiconductor suppliers from around the world. Both silicon carbide and gallium nitride semiconductors address the high voltage power semiconductor markets that are significant opportunities for our FOX wafer level test and burn-in systems and WaferPak full wafer contactors. Both device types are forecasted to grow significantly over the next several years and into the future.

“We are also seeing a strong recovery of our silicon photonics wafer level test and burn-in business after the weakness we saw during the pandemic. Halfway through this fiscal year, we have shipped over $5 million in systems, upgrades and WaferPaks to silicon photonics customers, which is over 300% of last fiscal year’s first half revenue for silicon photonics. This jump in revenue is also spread across multiple customers and much of it is for new product designs and qualifications. We have systems installed at over a half dozen customers testing silicon photonics devices used in 5G infrastructure, data and telecommunications transceivers, and a few yet to be announced applications that we are very excited about. With multiple market leaders announcing plans to integrate photonics transceivers into their microprocessors, graphics processors, and chipsets, we believe silicon photonics will become a significant market for wafer level test and burn-in over the next several years.

“Looking ahead, we continue to believe that we will receive production orders from additional silicon carbide companies beyond our current customers and begin shipping systems to meet their production capacity by the end of our current fiscal year that ends May 31, 2023. We are very optimistic for a strong second half of this fiscal year and believe the momentum will continue into our fiscal 2024.”

Fiscal 2023 Financial Guidance:

For the fiscal year ending May 31, 2023, Aehr is reiterating its previously provided guidance for total revenue to be $60 million to $70 million, with strong profit margins similar to last fiscal year. Aehr also continues to expect bookings to grow faster than revenues in fiscal 2023 as the ramp in demand for silicon carbide in electric vehicles increases exponentially throughout the decade.
