New York, January 29, 2026, 17:25 EST — After-hours
- Shares of Sandisk jumped following a profit beat and a surprisingly strong outlook for the next quarter.
- Datacenter sales surged, driven by management’s note that demand linked to AI infrastructure is fueling growth.
- Traders are eyeing if the after-hours surge sticks around for Friday’s open.
Sandisk shares surged in after-hours trading Thursday following its quarterly earnings report and an upbeat forecast signaling a robust next quarter. The stock climbed 12.4% to roughly $606 after the bell, having closed the regular session up 2.2% at $539.30. 1
The update matters since Sandisk offers one of the clearest signals on NAND flash demand — a memory chip used in solid-state drives and other storage — right now, as data-center expansions shift the baseline for “normal” demand.
The move comes amid a market that views storage as a stand-in bet on AI investments: when major cloud and chip companies ramp up, demand for high-performance storage to support their servers rises.
Sandisk reported fiscal second-quarter revenue jumped 31% from the previous quarter, hitting $3.03 billion. GAAP net income came in at $803 million, or $5.15 per share. Adjusted EPS, which excludes certain costs, was $6.20. Datacenter revenue surged 64% sequentially to $440 million. Having completed its split from Western Digital in February 2025, Sandisk projected fiscal third-quarter revenue between $4.40 billion and $4.80 billion, with adjusted EPS expected in the $12 to $14 range. 2
CEO David Goeckeler highlighted a stronger product mix and quicker adoption of enterprise SSDs, the solid-state drives powering servers. He said the company’s “structural reset to align supply with attractive, sustained demand” underpins disciplined growth. 3
Traders are now asking how much of the rally reflects real fundamentals versus positioning. Sandisk has long been a popular momentum play, and gains after hours often slip back once normal trading resumes.
Flash memory competition stays fierce, dominated by a handful of global suppliers who largely control pricing and capacity. Even a slight uptick in supply or a sudden halt in customer orders after heavy buying can quickly shift margins.
There’s a straightforward risk here: expectations have climbed steeply. Sandisk’s guidance is ambitious, and any slight slip in pricing, mix, or volumes might slam the stock after its recent surge.
Traders will be focused on whether Sandisk can stay above $600 when the market opens Friday, keeping an eye on any comments from management about pricing and supply discipline after the earnings call.
