Sandisk

Bull case

• SanDisk is attractive fundamentally because AI is shifting NAND from low-cost commodity storage toward a system-critical layer for inference, KV-cache, and data staging, where performance, endurance, and supply certainty matter more.
• Its vertically integrated model with Kioxia, the BiCS8/BiCS10 roadmap, and management’s 27% CAGR in bit output per wafer over five generations support stronger unit economics and growth without a proportional rise in wafer capacity, while Datacenter revenue surged from $960 million in FY25 to $5.15 billion in FY26.
• The FY28–FY30 framework for mid-to-high-teens revenue growth, ~80% gross margin, 75% operating margin, and 50% adjusted free-cash-flow margin is further reinforced by eight NBM customers covering about 65% of FY28 production and $93.9 billion of minimum contracted revenue, improving visibility and reducing cyclicality.

Bear case

SanDisk is exposed to a structurally cyclical NAND market, where any supply recovery, Chinese competition, or hyperscaler capex cuts could quickly reverse recent ASP strength and compress margins and EPS. Its core dependence on the Kioxia joint ventures also leaves it responsible for roughly half of fixed costs, while manufacturing disruptions, lower yields, or yen moves could pressure cash flow and capital needs. Although enterprise SSD progress and 10 customer agreements are positive, HBF and 3D Matrix Memory remain unmodeled, and ~60% of 2025 sales still depend on Edge demand that is vulnerable to PC and smartphone weakness.
