Aehr Reports Record Revenue in Third Quarter on Wafer Test and Burn-in Sales Driven by the Demand for Electric Vehicles

Fremont, CA (March 31, 2022) – Aehr Test Systems (NASDAQ: AEHR), a worldwide supplier of semiconductor test and reliability qualification equipment, today announced financial results for its third quarter of fiscal 2022 ended February 28, 2022

Fiscal Third Quarter Financial Results:

  • Net sales were $15.3 million, up 190% from $5.3 million in the third quarter of fiscal 2021.
  • GAAP net income was $2.2 million, or $0.08 per diluted share compared to a GAAP net loss of $735,000, or $0.03 per diluted share, in the third quarter of fiscal 2021.
  • Non-GAAP net income was $4.1 million, or $0.14 per diluted share, which excludes the impact of $880,000 stock-based compensation and a $1.0 million adjustment for excess and obsolete inventory related to legacy products. This compares to a non-GAAP net loss of $360,000, or $0.02 per diluted share, which excludes the impact of $271,000 stock-based compensation in the third quarter of fiscal 2021.
  • Bookings were $6.0 million for the quarter ended February 28, 2022.
  • Backlog as of February 28, 2022 was $26.9 million. Effective backlog, which includes all orders announced since the end of the third quarter, is over $30 million.

Fiscal First Nine Months Financial Results:

  • Net sales were $30.5 million, up 241% from $9.0 million in the first nine months of fiscal 2021.
  • GAAP net income was $3.7 million, or $0.13 per diluted share. This compares to a GAAP net loss of $2.6 million, or $0.11 per diluted share, in the first nine months of fiscal 2021.
  • Non-GAAP net income was $5.2 million, or $0.19 per diluted share, which excludes the impact of stock-based compensation, the adjustment for excess and obsolete inventory and forgiveness of the PPP loan. This compares to a non-GAAP net loss of $4.1 million, or $0.17 per diluted share, in the first nine months of fiscal 2021, which excludes the impact of stock-based compensation and the net gain related to the closure of Aehr’s Japan subsidiary during the first quarter of fiscal 2021.

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

“We finished the quarter with revenue of $15.3 million, our highest quarterly revenue on record, non-GAAP net income of $4.1 million, and a strong backlog of $26.9 million at quarter end. Our effective backlog, which includes all orders announced since the end of the third quarter, is over $30 million.

“We continue to see very strong interest and demand for wafer level test and burn-in of silicon carbide devices and see enormous growth potential for silicon carbide semiconductor test and burn-in to support the world-wide electrification movement in electric vehicles, power conversion, and power generation and storage infrastructure.

“During the quarter, four additional companies provided detailed wafer layouts to Aehr for their silicon carbide wafers, as part of their evaluation of using Aehr’s FOX-XP™ systems and WaferPak™ contactors for wafer level burn-in of their devices to meet the electric vehicle market and electrification infrastructure markets. We have provided those customers with the data confirming that we believe we can test their wafers and provide proposals and lead times to meet their needs. This includes another major supplier of silicon carbide devices who has now committed to an on-wafer benchmark and asked us to put a system on their test floor to demonstrate our capabilities. This is now the second of the top silicon carbide customers (beyond our current lead silicon carbide customer) to engage with us in what we call on-wafer benchmarking of their actual wafers.

“We have now made several proposals to customers to place orders to lock in lead times of our FOX™ systems and WaferPaks, and Aehr will provide on-wafer evaluations and validations for them within the lead time of the systems. In just the last few weeks, we met with multiple companies in both the US andEurope and are very encouraged by the positive feedback we received about their forecasts for wafer level burn-in needs and our expectations for winning this capacity with these prospective customers. This included very productive meetings with a major supplier of silicon carbide that is currently doing on wafer benchmarking and burn-in optimization investigations with our FOX system and WaferPaks today. It is apparent that wafer level burn-in will become the standard for silicon carbide devices, and based upon customer feedback, we continue to believe that Aehr is unique in our ability to meet the cost and volume production needs of this market.

“We continue to work closely with our lead silicon carbide test and burn-in customer, and earlier this month we announced follow-on orders from them for additional WaferPak™ Contactors that reflect multiple new silicon carbide device designs they are building to be qualified by their customers, along with several silicon carbide devices now qualified and ramping into production to meet demand for electric vehicles. This customer forecasts the need for additional systems to meet their goal of achieving a major share of the silicon carbide market. We continue to expect significant additional system and WaferPak purchases from them over the next several years and through the end of the decade.

“Forecasts from Canaccord Genuity estimate that the silicon carbide market for devices in electric vehicles, such as traction inverters and on-board chargers, as well as off-board charging stations used for electric vehicle charging, is expected to grow from fewer than 150,000 6-inch equivalent wafers of capacity in 2022 to more than four million wafers in 2030 to meet the more than 30 million electric vehicles anticipated to be built per year by then. This projected demand for just the electric vehicle silicon carbide wafers represents at least a $1 billion market opportunity for our wafer level test and burn-in systems and consumables over the next eight years. Canaccord also forecasts an additional capacity need of more than four million silicon carbide wafers to meet demand in 2030 for electrification infrastructure, industrial, and photovoltaic power devices. In our recent customer visits, we are now seeing demand surface for the wafer level burn-in of silicon carbide devices beyond electric vehicles that we believe is likely to become a significant market opportunity for Aehr as well.

“We are also seeing continued recovery and strengthening in the silicon photonics test and burn-in market, reflecting the post-Covid recovery that is driving devices to meet 5G and data center infrastructure build out. Several customers addressing the silicon photonics market have forecast additional FOX™ system and WaferPak or DiePak® contactor capacity needs over the next 12 months.

“In addition to the silicon carbide and silicon photonics markets that are strong drivers of our business, during the quarter we received an initial order from a current FOX-XP customer for our proprietary DiePak Carriers for a new optical sensor device, representing a new application for our FOX-XP system. This customer is a supplier of sensors to a major mobile device, personal computer, and consumer electronics manufacturer. This is the first order of DiePaks for this device, which is expected to move to production and will require additional DiePak Carriers and may also require additional FOX-XP system production capacity.

“We are excited about the unprecedented inbound interest and expanding growth opportunities we are seeing with a significant number of new potential customers that are evaluating the unique capabilities and cost effectiveness of our FOX-XP multi-wafer test and burn in system for their test and burn-in needs. We remain very focused on serving several large market opportunities we see ahead.”
