SanDisk Corp. (SNDK) surged 5.07% in overnight trading, extending a significant rally in memory chip stocks.

The movement is driven by the ongoing AI infrastructure buildout, which is shifting focus from GPU shortages to memory shortages. SanDisk, which became a pure-play NAND flash and enterprise SSD company after splitting from Western Digital, reported exceptionally strong fiscal third-quarter results with revenue of $5.95 billion, representing 252.1% year-over-year growth, and non-GAAP EPS of $23.41 that significantly exceeded expectations.

Furthermore, the company has secured multi-year customer lock-in agreements with minimum commitments totaling $42 billion, providing exceptional earnings visibility. Industry analysis indicates that as long as AI data center construction maintains high-intensity investment, storage demand, product pricing, and profit margins for leading companies like SanDisk will remain well-supported.
