Access earnings results, analyst expectations, report, slides, earnings call, and transcript.
Overview
The earnings call reveals several negative factors: a significant decline in gross margins, a non-GAAP net loss, and a substantial drop in cash reserves due to acquisitions and overhead costs. The withdrawal of revenue guidance adds uncertainty, and while AI market potential is noted, it is offset by current financial struggles. The Q&A highlights management's vague responses about future prospects and the impact of external factors, further adding to investor concerns. Despite some positive aspects, such as AI market growth, the overall sentiment leans negative due to financial and operational challenges.
Key Financial Performance
Revenue for fiscal 2025 $59 million, down 11% year-over-year. The decrease was attributed to a shift in revenue concentration from silicon carbide devices to other markets, including AI processors, gallium nitride power semiconductors, and data storage devices.
Non-GAAP gross margin for fiscal 2025 44%, compared to 49.6% in the prior year. The decline was due to less favorable product mix and higher manufacturing overhead costs.
Non-GAAP net income for fiscal 2025 $4.6 million or $0.15 per diluted share, compared to $35.8 million or $1.21 per diluted share in fiscal 2024. The prior year included a one-time tax benefit of $20.7 million.
Annual bookings for fiscal 2025 $61.1 million, up over 24% year-over-year. The increase was driven by sales of AI processor burn-in systems, wafer packs, and burn-in module boards, partially offset by lower orders for silicon carbide wafer packs.
Backlog as of year-end fiscal 2025 $15.2 million, with an additional $1.1 million in bookings received in the first 5 weeks of fiscal 2026, resulting in an effective backlog of $16.3 million.
Revenue for Q4 fiscal 2025 $14.1 million, a 15% decrease compared to $16.6 million in Q4 fiscal 2024. The decrease was due to delayed shipment of a FOX-CP system caused by tariff-related uncertainties.
Non-GAAP gross margin for Q4 fiscal 2025 34.7%, compared to 51.5% in Q4 fiscal 2024. The decline was due to lower revenue levels, less favorable product mix, and high manufacturing overhead costs.
Non-GAAP net loss for Q4 fiscal 2025 $248,000 or negative $0.01 per diluted share, compared to non-GAAP net income of $24.7 million or $0.84 per diluted share in Q4 fiscal 2024. The prior year included a one-time tax benefit of $20.7 million.
Cash, cash equivalents, and restricted cash at the end of Q4 fiscal 2025 $26.5 million, down from $49.3 million at the end of Q4 fiscal 2024. The decrease was due to the acquisition of Incal, facility upgrades, inventory procurement, and working capital needs.

Risk or Challenges
Revenue Concentration: The company previously had over 90% of its revenue concentrated in silicon carbide devices used in electric vehicles in fiscal '24. This concentration has decreased to less than 40% in fiscal '25, but the shift to new markets like AI processors introduces risks of dependency on emerging and potentially volatile markets.
Tariff Uncertainty: The company has faced delays in shipments and supply chain disruptions due to tariff-related uncertainties, particularly affecting the delivery of high-power probers sourced from Asia. This has delayed revenue recognition and impacted operational timelines.
Integration Challenges: The integration of Incal Technology into Aehr's operations incurred onetime restructuring charges and required significant financial and human resources. While the integration is complete, the process highlighted risks related to operational disruptions and cost overruns.
Market Diversification Risks: While the company is diversifying into AI processors, gallium nitride semiconductors, and other markets, these are emerging sectors with uncertain demand and competitive pressures. The reliance on new markets could pose risks if these markets do not grow as expected.
Regulatory and Legal Risks: The company has incurred higher legal and professional service fees and anticipates additional legal expenses to protect intellectual property rights in China. This could strain financial resources and operational focus.
Economic and Market Conditions: The slowdown in electric vehicle shipments and uncertainties in the silicon carbide market could impact revenue growth. The company has also withheld financial guidance due to tariff-related uncertainties and potential delays in customer orders.
Operational Capacity and Scalability: The company has made significant investments in upgrading its manufacturing facility and infrastructure. However, underutilization of manufacturing capacity during renovations led to higher overhead costs and lower gross margins.
Customer Dependency: The company has a few key customers representing over 10% of its revenue. Dependency on a small number of customers increases vulnerability to changes in customer demand or relationships.

Key Q&A
Q:Should investors think of the list of marquee names in the investor deck as current and previous customers or prospective customers?
A:The updated customer list reflects current customers from the Incal package part burn-in side of the business, not prospects. Some notable names are included, but not all historical customers are listed due to specific agreements.
Q:Will the 10% customers be named in the K filing?
A:The new SEC rules do not require naming 10% customers unless prior agreements exist. The company will not name them unless previously arranged.
Q:What is the potential size of the AI market compared to the silicon carbide market?
A:The AI market could be 3 to 5 times larger than the silicon carbide market. While AI may involve fewer wafers, the testing process and burn-in times make the market significantly larger.
Q:What caused the step down in gross margin quarter-to-quarter or year-over-year?
A:The step down was due to a mix issue, including lower-margin package part systems and consumables, as well as the full burden of the Incal facility during the quarter. Utilization was also lower due to operational moves.
Q:Why has the company’s enthusiasm around AI processors increased?
A:The company has proven its AI solutions work, delighted the first AI customer, and recognized the broader applicability of its technology. Customer interest and inbound inquiries have increased significantly.
Q:What is the company’s outlook for 2027, especially regarding TSMC’s reported plans to wind down gallium nitride foundry services?
A:The company expects significant growth by 2027 due to AI, silicon photonics, and silicon carbide markets. TSMC winding down gallium nitride services is not expected to negatively impact the company as other foundries or IDMs will likely absorb the business.
Q:How long will it take for new AI clients to pass qualifications and reach final decisions?
A:The company estimates that decisions could be made within six months, with potential orders placed thereafter.
Q:Is the first AI customer at the OSAT pleased, and are more orders expected?
A:Yes, the first AI customer is pleased, and more orders are expected this year.
Q:Are the three AI customers distinct?
A:Yes, the three AI customers are distinct, with different focuses on wafer level burn-in and package part burn-in.
Q:Did the 18-wafer, high-power silicon carbide system ship and book in the May quarter?
A:Yes, it shipped and booked in the May quarter as an upgrade to a previously purchased system.
Q:Will all future silicon carbide systems be high voltage?
A:Most future silicon carbide systems are expected to include high voltage capabilities, which come at a premium price.
Q:When will evaluations for HBM applications begin?
A:The company is finalizing its fine-pitch MEMS wafer pack technology, which enables HBM evaluations. This is expected to entice HBM customers soon.
Q:Review of Unclear Management Responses
A:The management avoided providing specific guidance for 2027, particularly regarding the impact of TSMC winding down gallium nitride services. They also used vague language when discussing the timeline for HBM evaluations and the potential for future orders from AI customers.
