Sandisk (SNDK) is one of the most profitable memory companies in the world right now, and the market is treating it like a cyclical stock near the top of its cycle. That mismatch is the investment case.
Why This Stock Now
The stock trades around $1,704, roughly 28% below its 52-week high of $2,354, even as the underlying business keeps accelerating. Q1 FY2027 earnings arrive October 29. Management guided revenue of $10.30 billion to $10.80 billion and non-GAAP EPS of $44 to $46 per share. The trailing twelve-month EPS sits at $73.76. Put those numbers together and the forward price-to-earnings multiple is under 8. For a company growing revenue north of 350% year over year, that is a striking figure.
The Business
Sandisk is a NAND flash memory manufacturer, spun out of Western Digital in February 2025. NAND is the technology inside enterprise solid-state drives: the storage layer every AI data center needs in volume. As AI inference workloads scale, so does the demand for fast, dense storage sitting beside the GPU clusters doing the work.
Sandisk has positioned itself to capture that demand through its proprietary BiCS8 technology and a portfolio running from consumer SSDs to enterprise and cloud storage products aimed at hyperscale deployments. The datacenter segment was a secondary business two years ago. Today it is the growth engine, up 645% year over year in the quarter ended April 2026.
Why Wall Street Is Paying Attention
The Q4 FY2026 results were almost difficult to categorize as normal corporate earnings. Revenue hit $8.97 billion, up 372% year over year, with a gross margin of 84.6%. Non-GAAP EPS of $39.25 beat the consensus estimate of $33.28 by nearly $6. Each of the four quarters in fiscal 2026 produced a beat, with an average surprise of roughly 381%.
That performance reflects two simultaneous forces: surging AI-driven enterprise SSD demand and NAND pricing that Gartner projects will rise roughly 234% in 2026, with meaningful relief not expected until late 2027. Sandisk benefits from volume growth and pricing strength at the same time. The board authorized an additional $14 billion buyback after Q4, bringing total remaining authorization to $15.5 billion against a market cap of roughly $250 billion.
What’s Driving the Opportunity
The Q1 FY2027 guidance midpoint of $10.55 billion implies 357% year-over-year growth off a period that was itself extraordinary. Analysts expect EPS to grow another 20% in the coming fiscal year. Yet SNDK carries a forward multiple of approximately 8 times, versus the Nasdaq-100 at roughly 35 times. That gap closes through earnings growth lifting the stock or through a re-rating once the market accepts this cycle is structural rather than temporary. Rosenblatt initiated a Buy at $2,400 in September. Goldman Sachs carried a $2,200 target as recently as July. The average analyst target implies more than 25% upside from here.
What Could Go Wrong
Memory cycles are brutal on the downside. The same pricing dynamics that lifted NAND 234% can reverse if supply discipline breaks. Sandisk competes with several major suppliers, and aggressive capacity expansion across the industry could compress gains faster than current forecasts assume. A slowdown in hyperscaler spending, or any architectural shift that reduces storage intensity per GPU, would hit demand before supply adjusts.
The 52-week range, $115 to $2,354, captures the volatility. Buyers here need conviction that the supply-demand gap holds through at least calendar 2027, which most industry forecasters expect but cannot guarantee.
The Bottom Line
Sandisk is a direct beneficiary of the AI storage surge, with a business growing at triple-digit rates, margins most software companies would envy, and a valuation that prices in a cyclical hangover that may not arrive for another 18 months. October 29 will reveal whether Q1 FY2027 guidance was conservative, as prior quarters strongly suggest it was. At 8 times forward earnings, the downside is more bounded than the multiple alone implies.
