    1. Given that revenue has been relatively flat at $65 million to $70 million for the past three years, can you provide clarity on when you expect to see a significant inflection point in sustainable top-line growth, and what factors will drive that growth?

    2. With the decline in gross margins due to the lower-margin Incal products, how do you plan to address this margin pressure, and can we expect margins to improve as the product mix changes in the future?

    3. Considering the recent patent infringement lawsuit in China and the geopolitical trade tensions, how are you managing the risks associated with your revenue and bookings from Chinese customers, and what impact could this have on your guidance?

    4. Given that some customer orders were delayed beyond the quarter end, leading to a revenue shortfall, can you elaborate on the issues causing these delays and what measures you're taking to prevent such timing issues in the future?

    5. While you've mentioned significant opportunities in new markets like AI processors, gallium nitride, and flash memory, can you provide more specific timelines and details on when these markets will meaningfully contribute to your revenue growth?

    Revenue Acceleration/Inflection
    New Projects/Investments
    • Revenue increased by 142% YoY to $18.3M, driven by strong shipments of the new FOX-XP wafer-level burn-in systems for AI processors and significant market diversification (from over 90% silicon carbide to less than 40%).
    • Effective backlog rose to $21.8M following robust bookings, even as near-term tariff uncertainties led the company to temporarily withdraw its guidance for the quarter.
    • Product integration and expansion efforts advanced, with the successful integration of the InCal acquisition and the introduction of new systems targeting AI, GaN, and hard disk drive markets.
