Sandisk Rockets 4000% on AI Memory Boom: Buy, Hold, or Take Profits?

After spinning off from Western Digital in February 2025, Sandisk Corporation SNDK has been on a remarkable upward journey, lifted by the accelerating demand tied to the artificial intelligence (AI) infrastructure boom. The NAND flash memory company has delivered gains of more than 4,000% over the past year, easily outpacing other major industry players, including the much-talked-about Micron Technology MU.  With a market capitalization of around $235 billion, Sandisk’s shares jumped from a 52-week low near $36 to roughly $1551 as of today, including a gain of over 500% in 2026 alone. But the rapid rise has sparked debate among investors. Given the highly cyclical nature of the memory business, some are concerned about whether the rally has already run its course. However, the company’s improving fundamentals suggest that there could still be meaningful upside ahead, making Sandisk a compelling investment opportunity. Let’s see in detail –  AI Demand and Strategic Deals Fuel Sandisk’s Growth Momentum In recent times, Sandisk has benefited from the rising AI data center demand for memory products amid tight industry supply. This tailwind is expected to continue, since the demand-supply imbalance is likely to persist for some time. For the fiscal third quarter, Sandisk’s revenues came in at $5.95 billion, up 97% sequentially and surpassing the company’s guidance range, according to investor.sandisk.com. Strong revenue performance was mostly due to a shift toward higher-value customers, primarily in the data center segment, which surged 233% and strong pricing power across its products. The revenue growth is expected to carry into the next quarter as well. For the fiscal fourth quarter, Sandisk expects revenues to come between $7.75 billion and $8.25 billion. Non-GAAP earnings per share (EPS) are expected to come in between $30 and $33, more than the fiscal third quarter’s $23.41, reflecting continued sequential growth. The company is also making long-term, high-value partnerships through its New Business Model (“NBM”) agreements. The company concluded three NBM agreements in the fiscal third quarter and added two more in the fiscal fourth quarter. These multi-year contracts have improved revenue visibility and strengthened customer stability. Buy Sandisk Stock Hand Over FistStrong AI data center demand and constrained memory supply are benefiting Sandisk.
