📝 Editor’s Comment (by K-STOCK Editor)
Management expects sustained Big Tech investments, traditional server refresh cycles, and broader AI adoption to support demand growth across high-performance, high-capacity, and low-power memory and storage solutions. To align with these trends, the company is executing on its plan to double 2025 HBM revenue while making preemptive investments for future HBM demand, including the Q4 2025 M15X opening, alongside HBM4 performance optimization and development of its 321-layer NAND portfolio.
Key monitoring variables going forward include the on-schedule opening of M15X in Q4 2025 and its preparation for 2026 DRAM/HBM production, along with progress in HBM4 customer optimization and the completion of 321-layer cSSD/eSSD development within the year.
