Recommendation

Despite a significant GAAP net loss driven by a non-cash impairment charge related to a strategic asset sale, the underlying operational performance is strong. The company exceeded Q4 revenue guidance, demonstrated robust growth in high-demand segments like AI and graphics, and saw sequential improvement in non-GAAP profitability. The $150 million cash infusion from the joint venture sale provides substantial capital for future investments and growth initiatives. The positive outlook for Q1 FY2026 and the focus on expanding market share in key applications suggest a favorable trajectory. For a seasoned investor, the one-time impairment is less concerning than the positive operational momentum and strategic capital allocation, making it an attractive long-term investment.
