SanDisk Stock Holds Near $1,740 After S&P 100 Rally as AI Storage Demand Drives Growth

Key Takeaways

• SanDisk stock closed at $1,737.99 on September 8 after surging nearly 12% in the previous session following confirmation of its addition to the S&P 100.
• Fiscal 2026 revenue jumped 175% to $20.25 billion, supported by higher NAND pricing and a 437% increase in data-centre revenue.
• The long-term trend remains bullish, but elevated volatility and short-term overbought signals increase the risk of a pullback.

SanDisk Stock Consolidates After S&P 100 Surge

SanDisk Corporation shares held near record territory on September 8, closing 0.12% lower at $1,737.99 after trading between $1,731.09 and $1,807.06. The modest decline followed an approximately 12% rally in the previous session, which lifted the company’s market capitalisation to nearly $273 billion.

The latest advance was largely driven by confirmation that SanDisk will join the S&P 100 before the US market opens on September 21. The memory-chip producer will enter the large-cap index alongside Dell Technologies, Palo Alto Networks and Arista Networks.

Index inclusion can generate additional demand because funds designed to track the S&P 100 must adjust their portfolios to reflect the new constituents. However, these flows are often concentrated around the effective date and do not necessarily determine the stock’s longer-term direction.

AI Storage Demand Drives 175% Revenue Growth

SanDisk’s underlying growth provides a fundamental backdrop for the rally. The company reported fiscal 2026 revenue of $20.25 billion, up 175% from $7.36 billion in the previous year.

Data-centre revenue climbed 437% to $5.15 billion, reflecting growing demand for NAND flash storage from cloud operators and artificial intelligence infrastructure customers. Edge-market revenue increased 195% to $12.16 billion, while consumer revenue rose 29% to $2.94 billion.

Fourth-quarter revenue reached $8.97 billion, representing a 372% year-over-year increase and a 51% sequential gain. Approximately two-thirds of the quarterly increase came from higher pricing, while one-third came from greater sales volumes. The company’s GAAP gross margin expanded to 84.6%, compared with 26.2% a year earlier.

SanDisk expects fiscal first-quarter 2027 revenue of between $10.3 billion and $10.8 billion. Non-GAAP diluted earnings are projected at $44 to $46 per share, while the adjusted gross margin is expected to remain between 83% and 85%.

These forecasts indicate that management expects favourable NAND pricing and strong demand to continue in the near term. Nevertheless, NAND remains a cyclical market in which supply increases, inventory corrections or slower customer spending can cause prices and margins to change quickly.

Long-Term Contracts Could Reduce NAND Volatility

SanDisk is attempting to reduce its dependence on short-term NAND pricing by expanding multi-year customer agreements. During its fiscal fourth-quarter update, the company said it had signed five additional New Business Model agreements after announcing five similar arrangements in April.

These contracts may provide greater visibility into future volumes and pricing. That could make SanDisk’s earnings less volatile than under a business model dominated by spot-market transactions, although the agreements cannot eliminate demand, customer concentration or execution risks.

The company also expanded its share-repurchase authorisation by $14 billion, bringing the remaining authorisation to approximately $15.5 billion. Repurchases could support earnings per share by reducing the number of shares outstanding, but the timing and scale of actual purchases will depend on cash generation and management’s capital-allocation decisions.

Investor Conferences Keep Management’s Outlook in Focus

SanDisk management participated in Citi’s Global TMT Conference on September 8. The company is also scheduled to appear at the Goldman Sachs Communacopia and Technology Conference on September 9 at 2:30 p.m. ET.

The presentations give investors another opportunity to assess NAND supply conditions, pricing trends, AI-related storage demand and the progress of SanDisk’s long-term customer contracts. Any changes to fiscal 2027 expectations or capital-allocation plans could influence the stock’s next move.

What Could Move SanDisk Stock Next?

SanDisk’s near-term direction may depend on whether strong AI storage demand and NAND pricing can offset concerns about valuation and the memory industry’s historical cyclicality.

The September 21 S&P 100 inclusion could support additional index-related trading, while management commentary from the latest investor conferences may shape expectations for fiscal 2027. Traders may also monitor the $1,790–$1,807 resistance zone and the $1,687 support area for signs that momentum is either extending or beginning to reverse.
