 Gayn Erickson, President and CEO of Aehr Test Systems, commented:
“As we noted in our preliminary earnings release in March, our third quarter results reflect delays in wafer level burn-in system orders for silicon carbide semiconductor devices used in electric vehicles. Due to this, we had revised our guidance for our fiscal 2024 full year ending May 31, 2024 to be greater than $65 million in total revenue and net income of at least $11 million, which we are reiterating today. We still expect to finish this fiscal year with annual revenue that is near or above our full year record.

“Last week we announced an initial order for our FOX-NP solution from a new customer that is a multi-billion dollar per year global semiconductor company, and is entering the silicon carbide market to address several applications that include automotive, industrial, and electrification infrastructure. This is our third straight new customer for silicon carbide that is primarily focused on applications other than electric vehicles, expanding our opportunity within silicon carbide beyond electric vehicles.

“We are still in continued engagements up to and including on-wafer evaluations with well over a dozen silicon carbide suppliers that are focusing on both electric vehicles and other applications and are forecasting production needs for wafer level test and burn-in of their devices with decision timelines that spread out over the next year. We are focused on the qualification process with as many new customers as possible, as once we have demonstrated our FOX wafer level test and burn-in solution using their own wafers, we have not yet lost a potential customer.

“Our discussions with customers indicate that the key markets Aehr is addressing for semiconductor wafer level test and burn-in have significant growth opportunities that will expand this year and throughout this decade, and we are seeing increased customer engagement in each of these markets. We have also seen a recent strengthening in the silicon carbide market for electric vehicles outside the US in what appears to be a shift in the market share of electric vehicle suppliers. This includes Asia where we recently had extensive and very productive and positive visits with a significant number of silicon carbide suppliers and electric vehicle suppliers that we will provide additional details on during our earnings call.

“According to many market forecasts, including the Semiconductor Industry Association, the semiconductor industry is expected to grow from $600 billion in 2022 to over $1 trillion at or around 2030. This acceleration is coming from mega market drivers including artificial intelligence (AI), green energy and decarbonization, and IoT-based digital transformation. Increased reliability concerns about semiconductors, a growing number of mission critical applications, and more multi-chip modules or heterogeneous integration with multiple devices being assembled in a single package are driving the need for wafer level burn-in. At semiconductor industry conferences around the world, we are seeing an increased focus on test and burn-in moving to wafer level before these devices are put into multi-chip packages and modules.

“These favorable macro trends are driving the business that drives Aehr Test and include:

  • silicon carbide power devices going into high-density modules for power conversion in electric vehicles;
  • gallium nitride power semiconductors going into automotive, solar, and other mission critical industrial applications;
  • silicon photonics integrated circuits being put into transceivers for data center infrastructure and optical chip-to-chip communication of CPU, GPU, and AI processors;
  • memory devices for solid state disk drives used in enterprise and data storage or for AI processors.

“Our continued investments in the FOX platform like the new 3.5 kW per wafer FOX-XP multi-wafer production system we began shipping last month also position us well to address the requirements of other new market segments that we believe we will be able to discuss over the next several months.

“As we head toward fiscal 2025, we are encouraged by our increasing engagements with current and potential customers and the long-term growth opportunities of all these markets.”

Fiscal 2024 Financial Guidance:
For the fiscal year ending May 31, 2024, Aehr is reiterating its previously provided guidance for total revenue of greater than $65 million and GAAP net income of approximately $11 million or more, or $0.38 per diluted share.

 –   Financial Tables to Follow  

Non-GAAP measures should not be considered a replacement for GAAP results. The non-GAAP measures indicated above are financial measures the Company uses to evaluate the underlying results and operating performance of the business. The limitation of these measures is that they exclude items that impact the Company’s current period GAAP measures. This limitation is best addressed by using these measures in combination with the most directly comparable GAAP financial measures. These measures are not in accordance with GAAP and may differ from non-GAAP methods of accounting and reporting used by other companies.

We believe these measures enhance investors’ ability to review the Company’s business from the same perspective as the Company’s management and facilitate comparisons of this period’s results with prior periods.
