SanDisk was spun off from Western Digital on February 21, 2025, becoming an independent pure-play NAND flash company. WDC distributed 80.1% of its SanDisk stake to shareholders, and WDC subsequently divested most of its remaining 19.9% through a secondary offering exchanged for WDC debt. SanDisk is now fully independent with its own balance sheet, management team, and strategic direction.

The company operates across three end markets. Edge ($1.678B, ~55% of Q2 revenue, up 21% QoQ) serves enterprise and consumer SSDs, flash memory modules, and embedded storage — demand "meaningfully exceeded supply" as AI PC adoption and replacement cycles drove richer configurations. Consumer ($907M, ~30%, up 39% QoQ, 50% YoY) sells retail flash drives, memory cards, and portable SSDs — mix shifted toward premium products; new Extreme Fit USB-C and Optimus SSD rebrand launched. Datacenter ($440M, ~15%, up 64% QoQ) provides enterprise SSDs for cloud and hyperscaler storage — management expects data center to become the largest NAND market in 2026 for the first time, and sees "meaningful" near- and long-term growth ahead. Enterprise SSD bits are in the "high teens" percentage of total bits shipped.

The NAND supercycle is the story — but management is now framing it as a "structural evolution" rather than a cycle. After a brutal downturn in 2023–2024 that drove NAND prices to record lows and forced production cuts, the industry has entered an extraordinary upcycle. AI workloads demand massive storage — inference in particular is "driving a meaningful increase in NAND content per deployment." Data center exabyte growth forecasts have been revised up three times: from mid-20s%, to mid-40s%, to now high-60% for 2026. Additionally, NVIDIA's KV cache architecture represents potential incremental demand of ~75–100 exabytes in 2027, doubling in 2028 — none of which is in current demand forecasts. Management sees customer demand "well above supply beyond calendar year 2026." SanDisk's Q2 FY2026 revenue of $3.03B was up 61% YoY with gross margins surging to 51.1%, and Q3 guidance implies a further step to 65–67% gross margins.

Management is actively pursuing multiyear long-term agreements (LTAs) with prepayment components to replace the traditional quarterly pricing model. One LTA has been signed and closed (terms undisclosed); several more are in the pipeline. CEO Goeckeler frames this as customers seeking "supply certainty" years out (conversations extend to 2029–2030) and argues the shift toward data center as the primary NAND market fundamentally changes industry dynamics — data center NAND is "not commodity" but a "highly strategic product" requiring specific performance characteristics.

The BiCS8 technology transition is the product driver. CEO called BiCS8 a "fantastic node" — featuring a 2-terabit die with strong QLC performance. BiCS8 is expected to reach majority of production by end of FY2026. The PCIe Gen5 high-performance TLC drive has been qualified at a second hyperscaler, with additional qualifications on track. BiCS8 TLC solutions to follow. The BiCS8 QLC storage-class product, code-named "Stargate," is advancing with two major hyperscalers and expected to ship for revenue within the next several quarters. Management is also developing "high bandwidth flash" (HBF) — a rearchitected NAND die plus custom controller designed for AI compute attachment — with active customer engagement and design work underway.
