Rosenblatt Slaps Street-High $2,400 Target on SanDisk

Rosenblatt Securities handed SanDisk (SNDK) a new "Buy" rating on Tuesday with a Street-high $2,400 price target, implying more than 30% upside from current levels — even after the stock has already multiplied roughly sevenfold since the start of 2026.

The call comes from Kevin Cassidy, Rosenblatt's senior analyst. His thesis rests on a structural shift in how the market values NAND flash memory, a product long treated as a commodity.

From commodity to mission-critical

For decades, non-volatile NAND flash was largely viewed as a commoditized component, subject to aggressive price-cutting cycles across mobile devices and personal computers. Buyers chased the lowest price. Suppliers fought brutal downturns.

Cassidy argues that era is ending. The rise of generative artificial intelligence models and data-heavy inference tasks is fundamentally altering storage requirements. High-performance enterprise compute platforms now demand maximum bit density, endurance, and supply certainty over bottom-dollar pricing.

That shift matters for one specific reason: NAND storage is becoming a mission-critical backbone within modern AI server clusters. As hyperscalers scale up training infrastructures, SanDisk's enterprise solid-state storage solutions are increasingly essential to preventing severe data delivery bottlenecks in complex neural network processing environments.

In plain terms, AI servers cannot afford slow storage. The companies building those servers will pay for certainty and performance, not just the cheapest gigabyte.

The manufacturing edge

The second pillar of Cassidy's bullish thesis is SanDisk's proprietary manufacturing advantage in 3D NAND flash architecture. The company's BiCS8 and BiCS10 technology platforms allow it to pack exceptional memory capacity into minimal physical silicon space.

That dense structural vertical stacking lets SanDisk deliver superior bit scaling without requiring cost-prohibitive, complex production footprint expansions. In his note, Cassidy said this operational efficiency provides a favorable bit-cost curve, giving the producer a durable cost-and-performance advantage over rivals.

A durable cost curve in a capital-intensive industry is a rare asset. It means SanDisk can expand output — and capture AI-driven demand — without the punishing capital spending that erodes margins across the semiconductor sector.

Wall Street context

Cassidy's target is the highest on the Street. It is also a contrarian signal in one sense: he is doubling down on a stock that has already delivered one of the most aggressive rallies of 2026, trading at about 7x its price at the start of the year. Most analysts would wait for a pullback before stamping a fresh target on a seven-bagger. Cassidy's note argues the repricing of NAND from commodity to AI infrastructure component is only beginning.

Barchart's own aggregated view aligns with the call. The platform currently holds an "88% BUY" average opinion on SanDisk.

The so-what for investors: the bull case no longer depends on memory cycle timing. It depends on whether AI data centers keep redefining what buyers will pay for flash storage — and whether SanDisk's BiCS architecture keeps its cost edge as hyperscaler demand scales.
