Bernstein has issued an "Underperform" rating for Kioxia Holdings Corp (285A.JP) with a price target of ¥40,000, suggesting over 50% downside risk from current levels. Analysts argue that while near-term NAND pricing and AI-driven demand are strong, earnings are likely to peak in CY2027 and normalize by CY2028 as supply from competitors like YMTC increases. The report cautions that current valuations unsustainably capitalize peak-cycle earnings and that long-term agreements may fail to prevent significant earnings volatility during a market downturn.
