SanDisk Corp. is set to release its fiscal 2026 fourth-quarter and full-year results after the U.S. market close on August 5th. This report will be a key test for whether the growth cycle driven by AI data center investments, rising NAND prices, and supply constraints can be sustained.
The market's primary focus is on the evolution of AI inference storage architectures and the company's guidance for fiscal 2027. Given Wall Street's broadly aggressive projections, there remains significant risk of post-earnings volatility.
Q4 Report Context: High Valuation, Recent Sharp Pullback
SanDisk Corp. shares have surged 411.7% year-to-date, dramatically outperforming storage peers like Western Digital (up 216.2%), Seagate (up 210.9%), and Micron Technology (up 188.3%). On a valuation basis, SanDisk currently trades at a premium. Based on its forward 12-month price-to-sales ratio of 3.90x, it is above the Zacks Computer Storage Device industry average of 3.31x and Micron's 3.89x, but below Western Digital's 10.09x and Seagate's 9.99x. Just before the earnings release, SanDisk experienced a sharp correction. Despite robust data center storage demand, investors reduced holdings in previously high-flying AI and memory chip stocks in July, leading to a roughly 47% monthly decline for SanDisk.
SanDisk and Market Performance Expectations
In its Q3 guidance, SanDisk projected Q4 revenue between $77.5 billion and $82.5 billion, driven by higher shipment volumes and improved pricing. The Zacks consensus estimate calls for revenue of $83 billion, a 336.64% increase year-over-year. Non-GAAP earnings per share are expected in the range of $30 to $33. The consensus EPS estimate is $34.24, which has been revised up 2.8% over the past 30 days. In the same quarter last year, the company reported EPS of $0.29. Wall Street's forecasts are more aggressive, with analysts expecting adjusted EPS of $34.80, slightly above the company's own guidance. Strong AI demand, higher NAND prices, long-term supply agreements, and a better product mix are expected to support earnings growth and margin expansion.
Key Earnings Focus Points: AI Memory Demand, NAND Pricing, and Guidance
1. Is AI Memory Demand Still Strong?
The most significant long-term catalyst for SanDisk is the rapid expansion of AI inference workloads. In its Q3 report, the company projected that inference, reasoning models, agentic AI, key-value caching, and RAG applications will require substantially more high-performance NAND storage. As hyperscalers build out AI infrastructure, enterprise SSD demand is expected to remain a primary growth driver for years to come. SanDisk's fiscal Q4 results are anticipated to benefit from continued strength in the data center business, with surging enterprise SSD demand being a major support. Hyperscale customers are expanding their AI infrastructure, keeping enterprise SSD momentum strong. Additionally, the company has started recognizing revenue from its QLC-based Stargate storage platform, complementing its successful TLC SSD portfolio. SanDisk has significantly strengthened its enterprise SSD business with industry-leading TLC SSDs while expanding into high-capacity QLC solutions via the Stargate platform. The company expects both product types to play complementary roles in AI data centers, increasing its exposure to the fastest-growing end market. Analysts echo this sentiment, believing the long-term AI memory narrative remains intact. Seagate's strong results and optimistic guidance suggest healthy cloud data center demand, while SK Hynix's results show that AI memory demand remains robust, even if it didn't meet the most extreme expectations. These outcomes reinforce the market's expectation that SanDisk will continue to benefit from AI infrastructure spending and enterprise storage demand. Recent announcements from cloud service providers support this view, indicating AI infrastructure spending continues to rise. Evercore analyst Amit Daryanani believes SanDisk's five New Business Model (NBM) agreements enhance the company's long-term revenue visibility. He estimates these deals will generate approximately $62 billion in committed revenue over several years, including over $11 billion in customer guarantees and prepayments.
2. Can NAND Pricing Ensure Profitability?
NAND pricing remains the single biggest factor influencing SanDisk's profitability. Higher NAND prices boost margins and earnings, while price declines pressure performance. The company believes NAND is becoming increasingly critical to almost all major technology platforms, providing diversified long-term demand drivers beyond the data center. SanDisk asserts that its advanced NAND architecture delivers industry-leading performance and enables mid-to-high teens annual bit growth through technology migration rather than expensive new capacity builds. The company's New Business Model (NBM) is expected to reduce the historical cyclicality of the NAND industry. These multi-year agreements provide committed demand, supply assurance, financial guarantees, and a mix of fixed and variable pricing, giving SanDisk higher revenue visibility, pricing stability, and more durable margins. The company expects the proportion of contract business to increase over time. After a period of prolonged oversupply, analysts anticipate NAND prices will remain firm as AI demand grows and memory manufacturers keep supply in check. Stable pricing should support SanDisk's margins and earnings over the coming quarters. Daryanani believes investors are underestimating SanDisk's long-term earnings and free cash flow potential. He expects NAND pricing to remain favorable as demand continues to outstrip supply in 2026 and 2027.
3. Guidance May Be More Important Than the Results Themselves
Wall Street expects SanDisk to deliver another strong quarter, primarily driven by robust AI data center demand for enterprise SSDs and ongoing tightness in NAND flash supply. Analysts generally expect Q4 revenue and EPS to surpass the company's official guidance range, with gross margins likely to remain near an unusually high level of around 80%. However, investors may pay more attention to management's forward outlook than the quarterly numbers. Following the stock's nearly 47% crash in July, the market is highly wary of a "high expectations trap." Even if quarterly results are impressive, shares could face downward pressure if management provides conservative guidance for fiscal 2027 or fails to clearly articulate how its New Business Model (NBM) long-term supply agreements will effectively smooth out the industry's cyclical volatility. Consequently, the core focus of this earnings report will be on whether management can use a strong future outlook to prove that the current ultra-high margins are a structural shift driven by AI, rather than a cyclical peak, thereby restoring market confidence.
Wall Street View: Still Optimistic
The market broadly believes SanDisk's recent stock price correction is not due to deteriorating fundamentals, but rather a confluence of factors. On one hand, the cooling of the AI trade narrative triggered profit-taking. On the other, investors are concerned about the memory sector's currently high valuations, potential future capacity releases, and the long-term sustainability of AI capital expenditure. Despite the short-term stock price pressure, Wall Street remains highly optimistic about SanDisk's long-term growth thesis. According to TipRanks, out of 12 analysts covering SanDisk, a high of 10 maintain a "Buy" rating. The core logic driving analyst bullishness remains unchanged: first, AI infrastructure buildout will continue to drive enterprise storage demand; second, NAND flash supply is expected to remain relatively tight; and third, the implementation of Long-Term Agreements (LTAs) will significantly improve the company's revenue visibility and effectively dampen the industry's cyclical swings. This sentiment is echoed by institutional views like that of Susquehanna analyst Mehdi Hosseini. Although he slightly lowered his price target for SanDisk from $3,250 to $3,050, he firmly maintains a "Buy" rating. He explicitly states that the target price adjustment is primarily due to revisions in the earnings model and some uncertainty regarding the final storage architecture to be adopted in the AI inference era, which does not affect his view of the company's long-term value.
