• The success of new market expansions (AI, GaN, silicon photonics) and customer evaluations is not guaranteed and depends on successful transitions to high-volume production.
• The company's financial performance has significantly declined year-over-year, indicating potential challenges in profitability and cash generation.

Future Outlook

The company anticipates order growth across nearly all market segments in fiscal 2026, with the possible exception of silicon carbide, where customer forecasts are back-half loaded for fiscal 2026 and stronger growth is expected in fiscal 2027. The company plans to boost research and development efforts to add more capabilities and resources for its expanding customer base. It expects to move to evaluation phases with additional AI companies during fiscal 2026 and believes it can capture a meaningful share of the total production burn-in market for AI processors. A major hyperscaler customer plans to ramp their AI device over the next year and is discussing next-generation processors. The company expects revenue from system upgrades and WaferPaks, as well as incremental FOX-XP system and WaferPak orders, to meet the capacity needs of the silicon photonics market in fiscal 2026. Despite current delays due to tariff-related uncertainty, the company remains optimistic about growth opportunities in diverse markets.

Management Comments

• "Fiscal 2025 was a transformative year for Aehr Test Systems, marked by significant progress on our strategic initiatives to expand our total addressable market, diversify our customer base, and enhance our product portfolio."
• "A major milestone was the successful launch and adoption of our first production wafer level burn-in (WLBI) system specifically for artificial intelligence (AI) processors. This breakthrough validates the feasibility and cost benefits of WLBI testing for high-power AI devices, attracting strong interest from leading processor companies considering high-volume adoption."
• "We are excited to report today that one of these companies has asked us to move forward with an evaluation for wafer level testing of one of their current high-volume processors. Based on their feedback, we believe that if this evaluation is successful, they intend to transition to high-volume production wafer-level testing, which would represent a significant opportunity for Aehr."
• "Aehr is the only company on the market that offers both a WLBI and a PPBI system for both qualification and production burn-in of AI processors, and we are very excited about our new AI product offerings and the expanded total addressable market they bring to us."
• "While the silicon carbide market growth has slowed due to a slower growth in EVs, we remain confident in its long-term opportunity for Aehr and our leadership in WLBI solutions for this sector."
• "We believe that nearly all the opportunities and market verticals we serve will experience order growth in fiscal 2026. The one exception may be silicon carbide, as customer forecasts for this market are back-half loaded, with stronger growth expected in our fiscal 2027."
• "While we remain confident in Aehrs long-term growth prospects, we continue to experience some timing-related delays in order placements due to tariff-related uncertainty, particularly in our first quarter. Accordingly, we are maintaining our cautious approach and are not reinstating specific guidance beyond what we have already stated, which is that we anticipate order growth across all our segments this fiscal year with the possible exception of silicon carbide."

Industry Context

The announcement reflects a broader trend in the semiconductor industry towards diversification beyond traditional markets and into high-growth areas driven by emerging technologies. Aehr's strategic pivot and expansion into AI processors, Gallium Nitride (GaN) power semiconductors, and silicon photonics aligns with the increasing demand for specialized testing solutions for these advanced materials and applications. The slowdown in the silicon carbide market, primarily tied to electric vehicle (EV) growth, highlights the cyclical and application-specific nature of semiconductor demand. The company's focus on GaN, which has a wider range of applications than silicon carbide, positions it to capitalize on a more diverse and potentially larger market in the coming decade. The emphasis on wafer-level burn-in (WLBI) and packaged part burn-in (PPBI) for AI processors addresses the critical need for reliability and testing in the rapidly expanding AI and data center infrastructure sectors, where high-power devices require robust testing solutions.

Comparison to Industry Standards

• The document states that Aehr is the only company on the market that offers both a Wafer Level Burn-In (WLBI) and a Packaged Part Burn-In (PPBI) system for both qualification and production burn-in of AI processors, indicating a unique competitive position rather than a direct comparison to specific industry benchmarks or comparable companies' results.
• The document mentions AMD, Nvidia, Intel, TSMC, and GlobalFoundries as companies with product roadmaps for devices utilizing optical chip-to-chip communication, but does not provide specific comparable financial results or project benchmarks against these companies.

Stakeholder Impact

• Shareholders: Negative impact from significant decline in revenue and net income, and cash used in operations, potentially leading to share price volatility. Positive long-term outlook due to strategic market expansion and new customer wins.
• Employees: Potential positive impact from plans to boost research and development efforts and build infrastructure and capacity for growth, suggesting future job stability and expansion.
• Customers: Positive impact from expanded product offerings (WLBI, PPBI for AI, GaN, silicon photonics), new higher-power systems, and enhanced automation, providing more comprehensive and advanced testing solutions.
• Suppliers: Potential positive impact from increased demand for components and services as the company expands its product portfolio and production capacity.
• Creditors: Potential concern due to the shift to cash used in operating activities and a decrease in cash reserves, though the overall cash position remains adequate for current operations.
