What happened
SanDisk (SNDK) stock jumped 6% on Tuesday to $1,887 after Rosenblatt Securities initiated coverage at Buy with a $2,400 target, arguing AI is repositioning NAND flash as critical infrastructure. Analyst Kevin Cassidy said AI computing platforms now demand storage density, performance, and supply certainty, lifting NAND beyond its old commodity role. Rosenblatt noted deals with eight major customers covering roughly 65% of SanDisk's fiscal 2028 production — unusual pricing visibility for a sector historically defined by boom-bust cycles. Memory rival Micron (MU) also gained 3% on the read-through. SanDisk entered the week up about 677% year-to-date, driven by fiscal 2026 revenue of $20.25 billion, up 175% versus a year earlier.
Why it matters
SanDisk is one of just a few companies that make NAND flash memory — the chips that store data in solid-state drives and AI servers — and Rosenblatt argues the market rules for those chips have changed permanently. AI workloads running at massive scale need storage that is fast, dense, and reliably sourced, commanding higher prices than the old commodity model allowed. The customer agreements with eight major buyers suggest the biggest tech companies already agree, pointing to less price volatility and more stable profit margins ahead.
