Sandisk Corp Dossier
Qualitative Analysis
Business overview
SanDisk Corporation (SNDK) operates as a standalone, pure-play NAND flash memory and enterprise solid-state drive (SSD) powerhouse. Originally founded in 1988, the company was acquired by Western Digital (WDC) in 2016 for $19 billion. Following activist investor pressure to unlock the conglomerate discount, SanDisk was spun off from Western Digital on February 21, 2025, returning to the public markets under the ticker SNDK. The company's business model is highly specialized, focusing on high-margin enterprise storage (accounting for over 55% of sales), client SSDs, and consumer flash. SanDisk leverages its proprietary BiCS (Bit Cost Scaling) 3D NAND technology, specifically its 218-layer BiCS8 architecture, to deliver high-density, high-performance storage solutions optimized for artificial intelligence (AI) workloads and hyperscale data centers.

Strategic Initiatives
Growth programs, investments, and their expected impact
Shift a growing portion of NAND sales to multi-year customer agreements built on committed volumes, enforceable contractual frameworks, minimum financial guarantees and structured pricing.
Expected impact: Improve demand and capacity-planning alignment, revenue predictability, cash-flow visibility and earnings durability while reducing exposure to conventional NAND pricing volatility.
Advance CBA-based BiCS9 and BiCS10 products and build an open High Bandwidth Flash ecosystem for storage-intensive AI inference. BiCS10 TLC sampling began in July 2026, while the ninth-generation 2Tb QLC design combines an advanced CMOS wafer with a proven memory array.
Expected impact: Deliver higher density, bandwidth and power efficiency, accelerate derivative development and improve manufacturing capital efficiency for AI, cloud and other data-intensive workloads.
Continue joint NAND research, development and manufacturing with Kioxia at Yokkaichi and Kitakami while scaling eighth- and tenth-generation products at the K2 Fab2 facility.
Expected impact: Preserve stable access to advanced NAND supply, manufacturing scale, joint-development synergies and capital-efficient multi-year bit growth.

Recent deals and strategic collaborations
Strategic Partnerships
The partnership provides shared development and manufacturing scale at Yokkaichi and Kitakami, including production of advanced CBA-based 3D NAND. The joint-venture framework has been extended through December 31, 2034.
Terms: Sandisk will pay Kioxia $1.165 billion for manufacturing services and continued supply availability in installments from 2026 through 2029.
Sandisk and SK hynix were the primary contributors to an open HBF specification intended to facilitate adoption of high-capacity, high-bandwidth near-compute flash in AI-inference systems; Google and Tenstorrent also joined the workstream.
