History Says This Will Happen to Sandisk Stock Heading Into Its Oct. 29 Report

SNDK has surged 478% in 2026 and heads into its Oct. 29 report with management guiding to $10.5B in Q1 fiscal 2027 revenue, a 357% year-over-year jump, and $45 in EPS.

The rally rests on AI data center demand for NAND flash memory, where supply remains critically scarce. That imbalance is the engine behind the guidance, which implies a near-fivefold revenue increase from the year-ago quarter.

History offers a pattern. Since SNDK's February 2025 spinoff from WDC, the stock has typically climbed in the run-up to earnings reports. Recent trading, though, has turned more volatile as investors weigh the inevitable downturn in the memory cycle. Interpretation: after a 478% move, the market is pricing in a great deal of perfection, and the debate has shifted from whether demand is real to how long the scarcity lasts.

The setup also matters for WDC, the former parent, since SNDK's results and commentary on NAND supply will shape sentiment around the spinoff relationship.
