Management Comments

• "While second quarter revenue was softer than anticipated, we made significant progress in both wafer-level burn-in (WLBI) and packaged-part burn-in (PPBI) segments and are very excited about our prospects moving forward."
• "Based on customer forecasts recently provided to Aehr, we believe our bookings in the second half of this fiscal year will be between $60 million and $80 million, which would set the stage for a very strong fiscal 2027 that begins on May 30, 2026."
• "This diversification of our markets and customers is significant, given our revenue concentration in silicon carbide for electric vehicles the last two years."
• "The progress we made this quarter with a significant number of customer engagements and production installations provides improved visibility into future demand."

Industry Context

The semiconductor industry is experiencing enormous growth driven by generative AI and the accelerating electrification of transportation and global infrastructure. These trends are increasing performance, reliability, safety, and security requirements for devices, making comprehensive test and burn-in solutions more essential. Aehr Test Systems is strategically positioning itself to capitalize on this by expanding its solutions for AI processors, gallium nitride power semiconductors, data storage, silicon photonics, and flash memory, diversifying its customer base beyond its previous concentration in silicon carbide for electric vehicles. The shift towards guaranteeing dependable operation throughout a product's lifetime, rather than just achieving functionality, is a fundamental industry change that benefits Aehr's offerings.

Comparison to Industry Standards

• The strategic partnership with ISE Labs aims to deliver advanced wafer-level test and burn-in services for next-generation HPC and AI applications, bringing "breakthrough capabilities to the market."
• Aehr's FOX-XP platform demonstrated its capability as a "competitive, cost-effective alternative to traditional packaged-part test and burn-in methods" for semiconductor memory devices during a benchmark with a global leader in flash memory.
• The company proposed a solution for High Bandwidth Flash (HBF), which it believes "represents a new industry standard."

Stakeholder Impact

• Shareholders: Potential for future revenue growth and increased profitability driven by diversification and strong demand in AI and data center markets, despite current quarter's underperformance. Reinstated guidance provides clarity.
• Customers: Access to advanced wafer-level and packaged-part test and burn-in solutions, accelerating time to market and improving performance for next-generation high-performance computing and AI applications.
• Employees: Continued focus on product development and market expansion suggests stability and potential for growth opportunities.

Next Steps

• Complete data collection for the benchmark evaluation of the new custom high-power fine-pitch WaferPak for AI processors this quarter.
• Make meaningful progress on benchmark evaluations with two other AI companies for wafer-level testing, expected to take approximately six months.
• At least one customer planning to transition to production later this calendar year for new device wins on the Sonoma platform for HTOL qualification.
• Receive substantial purchase orders from a lead PPBI production customer for AI ASIC production capacity, with requested shipments beginning in Q1 FY27.
• Customer for WLBI benchmark with flash memory leader to confirm correlation with existing processes.
• Further updates on the proposed solution for High Bandwidth Flash (HBF).
• Production ramp for silicon photonics lead customer beginning early next fiscal year, potentially driving orders in calendar 2026 for delivery in late 2026 to early 2027.

Key Dates

Recommendation

While the reported Q2 FY26 financial results were worse than anticipated and showed a decline year-over-year, the company has reinstated its guidance for the second half of fiscal 2026, indicating improved visibility. The strong forward-looking statements from management regarding expected bookings of $60 million to $80 million in H2 FY26, significant customer traction in AI processors and silicon photonics, and successful market diversification efforts (beyond silicon carbide) are highly positive for future growth. However, the current quarter's underperformance and net losses suggest that the turnaround is still in progress. An investor should hold to observe if the anticipated strong bookings and revenue growth materialize in the coming quarters, particularly in fiscal 2027, before making a more aggressive move. The increased cash position is a positive, but the operating losses need to be reversed.
