The thesis — preview.
SanDisk is the cheapest NAND pure-play that just printed 78% gross margin on +250% YoY revenue — own it as the AI-storage-tightness call and accept that the parabola will eventually correct. SanDisk fabricates 3D NAND flash memory — the storage substrate that sits one tier below DRAM in the memory hierarchy and absorbs the cost-sensitive bulk of AI training datasets, model checkpoints, agentic-AI memory, vector databases, and the enterprise SSDs that increasingly displace HDDs at the warm-tier of hyperscaler storage. Post-separation from Western Digital in early 2025, SanDisk is now the standalone NAND pure-play, jointly operating the Yokkaichi and Kitakami fabs with Kioxia under their decades-long manufacturing JV. Physically, SanDisk's wafers are produced at 100+ layer 3D NAND stacks, packaged into enterprise SSDs, client SSDs, and the new HBF (High Bandwidth Flash) form factor that the Kioxia-SanDisk roadmap is positioning as the AI-inference storage tier.…
