Fremont, CA (January 6, 2022) – Aehr Test Systems (NASDAQ: AEHR), a worldwide supplier of semiconductor test and reliability qualification equipment, today announced financial results for its second quarter of fiscal 2022 ended November 30, 2021.

Fiscal Second Quarter Financial Results:

  • Net sales were $9.6 million, up 471% from $1.7 million in the second quarter of fiscal 2021.
  • GAAP net income was $717,000, or $0.03 per diluted share, compared to a GAAP net loss of $2.0 million, or $0.08 per diluted share, in the second quarter of fiscal 2021.
  • Non-GAAP net income was $1.4 million, or $0.05 per diluted share, which excludes the impact of stock-based compensation, compared to a non-GAAP net loss of $1.7 million, or $0.07 per diluted share, in the second quarter of fiscal 2021.
  • Bookings were $29.1 million for the quarter ended November 30, 2021, the Company’s quarterly highest bookings on record, compared to $1.6 million in the second quarter of fiscal 2021.
  • Backlog as of November 30, 2021 was $36.1 million, the Company’s highest backlog on record.

Fiscal First Six Months Financial Results:

  • Net sales were $15.3 million, up 313% from $3.7 million in the first six months of fiscal 2021.
  • GAAP net income was $1.4 million, or $0.05 per diluted share, which includes the impact of forgiveness of $1.7 million in loans from the Paycheck Protection Program (“PPP”) received in fiscal 2020.

An explanation of the use of non-GAAP financial measures and a reconciliation of Aehr’s non-GAAP financial measures to the most directly comparable GAAP financial measures can be found in the accompanying tables.

Gayn Erickson, President and CEO of Aehr Test Systems, commented:
“We finished the second quarter with record bookings for a single quarter of $29.1 million and our highest backlog on record of $36.1 million. Including the announced orders since the beginning of the fiscal third quarter, our total bookings for the fiscal year to date is over $52 million.

“We continue to see very strong interest and demand for wafer level test and burn-in of silicon carbide devices, particularly for use directly in, and in support of, the electric vehicle market. We are ramping our FOX™ multi-wafer test and burn-in systems and full wafer WaferPak™ capacity to meet this upcoming silicon carbide market opportunity, which we believe will grow significantly over the next decade or more. We are only at the very beginning of this ramp as electric vehicles accounted for a very small percentage share of the overall market last year and are expected to be over 30% of total vehicles sold by 2030.

“During the quarter we received a $19.4 million order for our FOX-XP™ wafer level test and burn-in systems from our lead silicon carbide customer. This order was then followed by a $7.6 million order for WaferPaks that do not fully populate the systems, so we are expecting additional follow on WaferPak orders for these production FOX-XP systems. These systems and WaferPaks are being used to test and burn-in MOSFET devices in traction inverters in electric vehicle motor controllers, as well as both on-board and off-board electric vehicle chargers. This customer, a major automotive semiconductor supplier with a significant customer base in the automotive semiconductor market, continues to forecast significant additional system and WaferPak purchases over the next several years. Multiple industry forecasters and analysts expect the market for silicon carbide devices to grow at a compound annual growth rate (CAGR) of more than 30% over the next decade driven by demand from the electric vehicle market and other applications.

“In addition to a very strong backlog and forecast from our lead silicon carbide customer, we are currently engaged in discussions and/or evaluations with several other silicon carbide suppliers regarding their wafer level test and burn-in needs. This includes at least one large silicon carbide supplier that has moved to on-wafer evaluation and benchmarking of Aehr’s FOX-XP multi-wafer system for testing and burning in their silicon carbide wafers. We believe we will add several new silicon carbide customers that will ramp into production by next fiscal year on our solutions.

“Another positive is that we continue to see signs of strengthening in the silicon photonics test and burn-in market as our FOX multi-wafer systems and WaferPaks provide a very cost effective and scalable solution for “burning in” the optical lasers and stabilizing their output power while also removing any extrinsic or early life failures. In addition to the silicon photonics devices that are now ramping into production for fiberoptic transceivers for datacom and telecom applications such as data center and 5G infrastructure, several companies have made public announcements of their intent to integrate silicon photonics devices and co-packaged optics in high end processor applications and intra-chip as well as inter-chip communications within the next few years.

“During the last few months, we received orders from a current silicon photonics customer for six additional FOX-NP™ systems to support the characterization and product qualification of new types of photonics-based devices. This customer is expected to purchase new sets of WaferPaks to be used with these systems. As the applications and market for silicon photonics-based devices continue to grow, we expect this customer to continue to increase their capacity in the future.

“Several other customers addressing the silicon photonics market have also forecast additional FOX system and WaferPak or DiePak™ contactor capacity needs over the next 12 months. These include needs to address incremental production capacity as well as capacity to address new customer and new product qualification and engineering. Silicon photonics devices address the 5G and data center infrastructure industry as well as several other key markets today, and Yole Research predicts that the silicon photonics transceiver market alone will reach $4.6 billion in 2026, with a CAGR of 25% between 2021 and 2026.

“We remain very focused on serving the very large market opportunities we see ahead, which include the significant opportunity for test and burn-in of silicon carbide devices for electric vehicles and electrification infrastructure, silicon photonics devices for data center and 5G infrastructure, and 2D/3D sensors for
mobile and wearable devices. With our record bookings and the strength of our semiconductor test and burn-in solutions, we are confident in our ability to deliver significant revenue growth and are reiterating our guidance for revenue for the year.”

Fiscal 2022 Financial Guidance:
For the fiscal year ending May 31, 2022, Aehr is reiterating its previously provided guidance for full year total revenue of at least $50 million, and to be profitable for the fiscal year at these revenue levels based upon its operating model.
