Sandisk Stock Jumps 6% as AI Memory Rally and Long-Term Contracts Lift Sentiment

Key Takeaways

• Sandisk shares climbed 6.2% to $1,614.39 on September 17, rebounding alongside a broad rally in semiconductor and AI infrastructure stocks.
• Micron gained 5.5%, Intel rose 7.7%, and Nvidia advanced about 2.6% as easing Treasury yields and lower oil prices helped revive demand for technology shares.
• Bullish analyst targets and Sandisk’s multiyear New Business Model agreements have strengthened the long-term earnings case, although valuation, contract execution and the cyclical NAND market remain important risks.

Sandisk Shares Rally as Chip Stocks Recover

Sandisk shares rallied sharply on Thursday, September 17, as investors returned to memory, semiconductor and artificial intelligence infrastructure stocks following a sector-wide selloff earlier in the week.

The stock closed 6.2% higher at $1,614.39, extending its recovery as the wider chip sector moved firmly higher. Micron Technology gained about 5.5%, Intel jumped 7.7%, and Nvidia advanced roughly 2.6%. Marvell Technology, Advanced Micro Devices and Arm Holdings also recorded strong gains, showing that the buying was not limited to a single part of the semiconductor market.

The rebound came as some of the macroeconomic pressure on growth stocks eased. Crude oil prices declined for a second consecutive session, reducing immediate concern that elevated energy costs would keep inflation persistently high. Treasury yields also moved lower after the Federal Reserve delivered a widely anticipated 25-basis-point rate increase.

Lower bond yields can support highly valued technology companies because they reduce the discount rate applied to expected future earnings. For capital-intensive AI infrastructure businesses, they may also ease concerns about financing costs for new data centres, servers and computing capacity. However, the Fed has left the possibility of further tightening open, meaning the rate backdrop remains a source of uncertainty.

AI Memory Demand Keeps Sandisk in Focus

Sandisk’s rally reflects more than a broad improvement in risk sentiment. The company has become a major market proxy for the rapid growth of NAND flash demand linked to AI data centres, enterprise solid-state drives and increasingly storage-intensive inference workloads.

AI training has historically placed the greatest emphasis on processors and high-bandwidth memory. The expansion of inference is broadening the infrastructure requirement. Large volumes of generated data, model parameters and key-value cache information must be stored and retrieved efficiently, supporting demand for higher-capacity enterprise flash products.

Sandisk said at its August Investor Day that the total addressable market for enterprise data-centre flash could reach 1.2 zettabytes by 2030. The company also highlighted BiCS9 QLC and BiCS10 QLC products designed to increase storage density, improve performance and reduce power consumption for AI-driven workloads.

This positioning helped Sandisk produce an exceptional fiscal fourth quarter. Revenue reached $8.97 billion, rising 51% from the previous quarter and 372% from a year earlier. Fiscal 2026 data-centre revenue increased 437% to $5.15 billion, while the company’s quarterly gross margin expanded to 84.6%.

Those figures demonstrate the strength of the current memory cycle, but they also create a demanding comparison base. Investors must assess whether AI-related storage demand can remain strong enough to support pricing and margins as suppliers adjust capacity and customers refine their infrastructure spending plans.

New Business Model Contracts Support Earnings Visibility

A central part of the bullish Sandisk investment case is the company’s New Business Model, or NBM, contract structure. Unlike conventional NAND transactions that can leave suppliers heavily exposed to short-term pricing cycles, the new agreements include committed volumes, enforceable contractual terms, minimum financial guarantees and structured pricing mechanisms.

Sandisk has signed NBM agreements with eight customers. The contracts are expected to cover approximately 50% of the company’s bit output in fiscal 2027 and about two-thirds in fiscal 2028. Figures discussed in investor-related analysis place the agreements at approximately $93.9 billion in minimum contracted revenue, supported by financial guarantees, although the ultimate revenue recognised will depend on contract terms, customer demand and execution over several years.

The strategic importance of the agreements lies in visibility rather than the headline value alone. Greater certainty over customer volumes can help Sandisk plan production, allocate capital and manage inventory more efficiently. Structured pricing may also reduce the severity of earnings swings that have traditionally affected NAND producers when supply exceeds demand.

Management expects revenue to grow at a mid-to-high-teen annual rate between fiscal 2028 and fiscal 2030. It is also targeting non-GAAP gross margins of approximately 80%, operating margins near 75% and an adjusted free-cash-flow margin of around 50% during that period. These are forward-looking targets rather than guaranteed results and rely on sustained demand, disciplined industry supply and successful execution.

Analyst Price Targets Add to Bullish Momentum

Positive analyst commentary has provided another catalyst. Susquehanna reiterated a Buy rating on Sandisk and set a $2,745 price target, implying substantial potential upside from the September 17 closing price. The wider analyst consensus also remains constructive, although individual targets vary significantly and should not be treated as forecasts that must be reached.

The bullish view is based on the possibility that the market still underestimates how much Sandisk’s earnings profile has changed. Stronger enterprise SSD demand, elevated NAND pricing and longer-term customer commitments could make revenue and cash flow less volatile than in previous memory cycles.

At the same time, the stock’s extraordinary advance has increased sensitivity to any disappointment. Sandisk has experienced several steep pullbacks in 2026 even after periods of rapid gains, reflecting uncertainty over AI capital spending, memory pricing and the durability of unusually high margins. A high price target can reinforce positive sentiment, but it does not remove the risks created by a volatile valuation or a cyclical end market.

What Could Move Sandisk Stock Next?

The near-term direction of Sandisk stock is likely to depend on both company-specific execution and wider market conditions. Investors will watch NAND contract pricing, enterprise SSD shipments, data-centre customer spending and progress toward the company’s fiscal 2027 guidance.

Interest rates will remain another key variable. Further increases in Treasury yields could pressure richly valued technology shares, while a renewed decline in oil prices and inflation expectations may provide support. Developments across Micron, Kioxia and other memory producers will also offer signals about supply discipline and industry pricing.

The September 17 rally showed that demand for AI and memory exposure remains strong when macroeconomic pressure eases. Sandisk’s NBM agreements and rapidly expanding data-centre business provide a credible foundation for longer-term growth, but the shares are likely to remain volatile as investors test whether current earnings power can persist through the next phase of the NAND cycle.
