Memory used to be a cyclical industry. Artificial intelligence (AI) has broken that pattern, as AI accelerators run on High-bandwidth memory (HBM), a cutting-edge, vertically stacked DRAM technology designed to meet the massive data needs of large language models (LLMs). Demand has surged so rapidly that the bottleneck has shifted from securing customers to producing enough chips.
Memory storage product supplier Sandisk Corporation (SNDK) is reaping the benefits of this huge demand. After the planned spin-off from Western Digital Corporation (WDC) last year, its stock has skyrocketed from its initial price, as memory is being recognized as a strategically important input for AI workloads.
Recently, it was announced that Sandisk would be added to the MSCI World Index as of the market close of Aug. 31. This is important for Sandisk because it brings passive buying through ETFs and index funds that track the index. It is also important for analyst coverage, as inclusion means the company meets the index's size and free-float criteria.
Let's take a closer look at Sandisk now.
About Sandisk Stock
Sandisk Corporation designs and sells flash memory and storage products, including solid-state drives (SSDs), memory cards, and USB drives. Headquartered in Milpitas, California, the company makes chips and storage systems used in data centers, smartphones, PCs, cars, and consumer electronics.
Spun off from Western Digital in 2025, Sandisk develops its own flash technology and works with partner Kioxia to manufacture wafers in Japan, with assembly and testing in Malaysia and China. Its products support AI workloads, cloud computing, gaming, and everyday digital storage needs. The company has a market capitalization of $217.43 billion.
Sandisk sits at the center of an AI-driven NAND flash shortage that has sent memory prices and profits soaring. This pure-play AI storage narrative has sent the stock soaring. Over the past 52 weeks, SNDK stock has gained a whopping 2,851%, while it has gained 532% year-to-date (YTD). It reached a 52-week high of $2,354.39 on June 22 but is down 36% from that level.
Sandisk has a 14-day relative strength index (RSI) of 49.32, which is reasonable considering its skyrocketing price. Moreover, on a forward-adjusted basis, its price-to-earnings (non-GAAP) ratio of 6.94x is lower than the industry average of 22.69x.
Sandisk Posted Record Q4 as Data Center Demand Drives Surge
For the fourth quarter of fiscal 2026 (quarter ended July 3), Sandisk's revenue surged by a whopping 372% year-over-year (YoY) to $8.97 billion, as data center revenue climbed from $213 million to $2.98 billion and edge revenue rose 392% YoY to $5.43 billion. The company's non-GAAP gross margin climbed by 58.2 percentage points from the prior-year period to 84.6%. Its non-GAAP EPS increased from $0.29 in the year-ago period to $39.25.
For the first quarter of fiscal 2027 (current quarter), Sandisk expects its revenue to be around $10.30 billion to $10.80 billion and non-GAAP EPS to be in the $44 to $46 range. Wall Street analysts are extremely optimistic about Sandisk's future earnings. They expect the company's EPS to climb considerably YoY to $45.22 for the current quarter. For fiscal 2027, EPS is projected to surge 201.1% to $208.92, followed by a 20.7% growth to $252.16 in fiscal 2028.
What Do Analysts Think About Sandisk's Stock?
Recently, analysts at Mizuho maintained a bullish "Outperform" rating on the stock but lowered the price target from $1,900 to $1,875. After its recent quarterly earnings release, analysts at JPMorgan reinstated an "Overweight" rating on Sandisk and set a $2,250 price target. Analyst Harlan Sur's reinstatement of the company's rating suggests it is considered a top memory NAND flash supplier in a market transforming due to AI demand.
After Sandisk's investor day, Wedbush Securities analyst Matt Bryson kept an "Outperform" rating and a $2,000 price target. In a note, Bryson wrote that memory will likely become cyclical again. He also is not ready to build Sandisk's newer High-Bandwidth Flash (HBF) memory technology into his estimates until adoption becomes clearer.
Memory giant Sandisk is an extremely popular name on Wall Street, with analysts awarding SNDK stock a consensus "Strong Buy" rating overall. Of the 24 analysts rating the stock, a majority of 20 analysts have given it a "Strong Buy" rating, one analyst rated it "Moderate Buy," while three analysts are taking the middle-of-the-road approach with a "Hold" rating. The consensus price target of $2,144.26 represents a 44% upside from current levels. Moreover, the Street-high price target of $3,000 reflects a 102% upside.

Executive Summary
Full Take
The narrative surrounding Sandisk is a case study in how transformative technology creates structural shifts in an established industry, moving from cyclical patterns toward AI-driven demand spikes. The initial premise—that memory use transitioned from being cyclical to being tied directly to the massive data requirements of LLMs and HBM—represents a fundamental revaluation where physical infrastructure supplies become strategic assets rather than mere commodity inputs. The shift in market recognition is evidenced by the significant stock appreciation, which reflects investor anticipation of sustained, non-cyclical growth tied to AI infrastructure deployment.
The pattern observed here involves the co-option of underlying supply chain entities into narratives of technological supremacy. Sandisk’s success highlights that control over specialized memory technology (NAND flash) in an AI ecosystem grants disproportionate market leverage. The tension lies in the divergence between short-term speculative enthusiasm, reflected in soaring stock gains and optimistic earnings forecasts from analysts, and the stated caution from some observers regarding the future cyclicity of the memory market as adoption curves solidify for newer technologies like High-Bandwidth Flash (HBF). The implications suggest that future valuation will depend not only on current demand but also on the successful integration and perceived long-term viability of proprietary technology stacks within the evolving AI landscape.
Bridge questions: How will the timeline for the transition to HBF memory adoption impact Sandisk's projected earnings stability? What are the structural risks if the AI demand shift reverses or slows down unexpectedly? How do sustained shifts in strategic positioning, such as the MSCI inclusion, balance the short-term volatility generated by technological hype?
