Western Digital (WDC) Status Update summary

Market and industry dynamics

• NAND market is experiencing a strong recovery, driven by increased pricing, better supply-demand balance, and new demand drivers, especially from AI and data center applications.

• The industry is moving away from the 'layers race' and focusing on premium nodes, with a shift toward performance, capacity, and power optimization for specific use cases.

• Oversupply and overinvestment in the 3D era led to industry-wide unprofitability, but a new capital discipline is emerging, targeting 18-20% bit growth and $11-13B annual capital spend.

• The market is transitioning to a long-tail, multi-node environment, requiring customers to select nodes optimized for their applications.

Capital and supply-demand strategy

• Capital investment decisions are now based on market stabilization, margin expansion, and demand visibility, rather than automatic annual bit growth targets.

• The industry is expected to stabilize at lower capital intensity, with a focus on premium applications and organic demand rather than price-induced demand.

• Conservative capital planning is preferred to avoid overshooting market demand, with flexibility to ramp up if needed.

Technology and innovation roadmap

• Four innovation vectors are prioritized: lateral scaling, logical scaling (e.g., QLC), vertical scaling (layers), and architectural scaling, with lateral and logical scaling offering the best cost-to-bit growth ratio.

• BiCS8, featuring CMOS Bonded Array (CBA) technology, delivers significant performance, density, and power improvements, and is the fastest ramping node in company history.

• The world's highest capacity 2Tb QLC die was previewed, targeting AI and data center needs.

• QLC is central to future cost reduction and bit growth, with BiCS8 expected to drive mass adoption.
