Sandisk Rises as AI Memory Demand Story and Western Digital Share Swap Stay in Focus

Sandisk (SNDK) is up 5.9% today. Here is some analysis on what might have caused this price movement.

Analysis: The most likely driver appears to be continued enthusiasm around Sandisk’s sharply improving NAND and SSD earnings outlook, reinforced by its recent results and strong fiscal fourth-quarter guidance. Today’s move may also reflect investors reacting favorably to Western Digital’s planned June 22, 2026 exchange of its remaining 1,038,681 Sandisk shares, which could reduce a lingering ownership overhang.

Details:

Sandisk’s latest quarterly report showed revenue of $5.95 billion, up 97% sequentially, with datacenter revenue up 233% and results helped by higher pricing and a mix shift toward higher-value customers.

The company guided for fiscal fourth-quarter revenue of $7.75 billion to $8.25 billion and non-GAAP diluted EPS of $30.00 to $33.00, signaling that the strong memory pricing environment may continue.

Western Digital disclosed on June 11 that it agreed to exchange 1,038,681 Sandisk shares for its own stock, with the transaction expected to close on June 22, 2026.

Western Digital had previously said it intended to monetize its remaining Sandisk stake, so completion of that process could be seen as removing uncertainty around future share disposals.
