SanDisk Corporation shares traded lower on Thursday, retreating approximately 1.5% to $742.50 by mid-morning, despite a significant price target increase from Citi. The stock opened the session at $707.15 and dipped as low as $694.44, reflecting a cautious market mood. The movement contrasted with the broader, uneven performance in the memory and storage sector, where Western Digital—SanDisk's former parent—posted a modest gain while competitor Micron Technology saw a sharper decline of nearly 2.9%.
AI Demand Drives Fundamental Strength
The backdrop for SanDisk remains robust, anchored by explosive demand for NAND flash memory from artificial intelligence infrastructure. Since its corporate separation from Western Digital in February 2025, SanDisk has emerged as a pure-play U.S. investment tied directly to this trend. Data centers are increasingly reliant on NAND, the technology underpinning solid-state drives (SSDs), to manage escalating AI workloads. This dynamic was evident in SanDisk's latest quarterly report, where data-center revenue soared 64% sequentially for the period ending in January.
On January 29, the company reported second-quarter revenue of $3.03 billion, a striking 61% increase from the same period a year earlier. Non-GAAP earnings reached $6.20 per share. Management provided strong forward guidance, projecting current-quarter revenue between $4.40 billion and $4.80 billion. CEO David Goeckeler attributed the powerful results to an improved product mix, accelerated enterprise SSD deployments, and sustained AI-driven demand.
Analyst Sentiment and Valuation Divergence
Citi analyst Asiya Merchant reinforced a bullish stance, elevating her price target on SanDisk to $875 from $750 while maintaining a Buy rating. Merchant emphasized that storage demand shows no signs of abating, projecting that "NAND demand will exceed supply for the foreseeable future." This optimism stands in stark contrast to the broader Wall Street consensus. According to data from TipRanks, the average analyst price target for SanDisk sits at $688.33, based on twelve Buy and three Hold ratings. This average implies potential downside from Wednesday's record closing price of $753.69.
The valuation debate is intensifying. Analysis from Simply Wall St. on Wednesday illustrated the uncertainty, calculating a fair value of approximately $717 using an earnings-multiple model—close to the stock's trading level. However, its discounted cash flow model produced a far more aggressive valuation of $1,993.28. This wide discrepancy underscores how sensitive the stock's perceived worth is to assumptions about future profit margins, pricing power, and the longevity of tight AI-related demand.
Industry Capacity Concerns Emerge
The rally in memory stocks now faces a classic industry test: the cyclical nature of supply and demand. While current conditions are tight, significant capital expenditure increases across the sector signal that new capacity is on the way. This was highlighted by Micron's actions late Wednesday. The chipmaker not only surpassed Wall Street's expectations and forecast third-quarter revenue around $33.5 billion but also announced a substantial boost to its capital spending plans.
Micron raised its fiscal 2026 capital expenditure forecast by $5 billion, pushing the total above $25 billion. This aggressive investment plan unsettled some investors, serving as a reminder that shortages are typically temporary. Mike O'Rourke, chief market strategist at JonesTrading, noted that the expanded spending blueprint makes it clearer that the memory business is likely to "return to its commodity nature in coming years as capacity comes online."
SanDisk's management is actively working to mitigate this inherent volatility. In a January interview, CEO Goeckeler told Reuters that major AI clients operating inference data centers—where stored data is processed to generate responses—are prioritizing guaranteed flash supply over price. "Customers prefer supply over price," he stated. To secure its own supply chain, SanDisk recently extended its partnership agreement with Japanese memory producer Kioxia through the end of 2034.
The current market action suggests investors are pausing to weigh the powerful, near-term tailwind from AI against longer-term cyclical risks and rich valuations. While the fundamental demand story for NAND flash in data centers remains compelling, the sector's history and rising capital investment are introducing a note of caution, testing the resilience of the AI-driven rally in memory stocks.
