Executive Summary
                In Q4 2025, Aehr Test Systems reported a revenue of $14.1 million, reflecting a 15% year-over-year decrease driven by delayed shipments due to tariff-related uncertainties. The gross profit margin dropped significantly from 51.5% a year ago to 34.7%, a consequence of changing product mix and elevated manufacturing costs related to the integration of acquired operations. Despite the challenges, management highlighted a transformative year with AI processor testing now generating over 35% of revenue, a notable departure from zero the previous year. Looking forward, Aehr expects robust growth as it continues to diversify its market focus, particularly in AI and other semiconductor applications. Chris Siu, CFO, anticipates an effective backlog of approximately $16.3 million, suggesting a positive trajectory for the upcoming quarters.
