Sandisk delivered a striking fiscal fourth-quarter earnings beat as rising demand from artificial-intelligence data centers pushed flash-memory pricing, revenue and profitability sharply higher.
The storage-chip company reported revenue of $8.97 billion, up 51% from the previous quarter. Non-GAAP earnings reached $39.25 per share, comfortably exceeding analysts’ expectations. GAAP net income totaled $6.90 billion, or $43.97 per diluted share. Sandisk said approximately one-third of its sequential revenue growth came from higher shipment volumes, while two-thirds came from stronger pricing.
Despite the exceptional quarter, Sandisk stock declined in extended trading. Investors focused on a first-quarter outlook that appeared less impressive relative to elevated expectations following the stock’s enormous 2026 rally.
The results highlight the central debate surrounding SNDK stock: the company is benefiting from one of the strongest storage-market environments in years, but its valuation increasingly assumes that unusually high prices, margins and AI-related demand will persist.
Sandisk Revenue and EPS Crush Forecasts
Sandisk’s fourth-quarter results came in well above Wall Street estimates.
The company’s $8.97 billion in revenue exceeded the approximately $8.39 billion consensus cited by Reuters. Adjusted earnings of $39.25 per share also surpassed the $34.45 analyst estimate. Data-center revenue more than doubled sequentially to approximately $2.98 billion.
The magnitude of the growth reflects both improving demand and a favorable pricing environment for NAND flash memory.
NAND is a type of non-volatile memory used in enterprise solid-state drives, smartphones, personal computers, memory cards and other storage products. Unlike volatile memory, NAND retains information when power is removed.
Artificial-intelligence systems require enormous quantities of stored data. Models must access training datasets, generated content, databases and application information, increasing the need for high-performance enterprise storage.
That demand is benefiting Sandisk’s data-center products, particularly enterprise solid-state drives. These drives can offer faster access times and lower power consumption than conventional hard-disk drives for certain workloads.
Higher Pricing Drives Most of the Growth
Sandisk said pricing accounted for roughly two-thirds of its sequential revenue increase, while volume contributed the remaining one-third.
That breakdown is important for investors.
Higher shipment volumes suggest underlying demand is expanding. Higher prices indicate that storage supply remains tight enough for manufacturers to charge more for each unit sold.
Pricing can improve profit rapidly because the cost of manufacturing an additional chip may not rise as quickly as its selling price. This operating leverage can produce dramatic increases in gross margin and earnings during favorable memory cycles.
However, price-driven growth can also be cyclical. Strong prices encourage manufacturers to increase production capacity, while customers may eventually reduce purchases or use inventory more efficiently.
The durability of Sandisk’s earnings therefore depends on whether AI storage demand continues growing faster than available supply.
Management is attempting to reduce this cyclicality by signing longer-term customer agreements rather than relying heavily on short-term quarterly purchasing arrangements.
Long-Term Contracts Improve Revenue Visibility
Sandisk has shifted a growing portion of its production toward multiyear supply agreements.
The company has eight agreements with six customers worth at least $93.9 billion. The median contract duration is four years. Approximately half of Sandisk’s fiscal 2027 output is expected to be sold under these arrangements, increasing to about two-thirds in fiscal 2028.
These contracts could provide greater revenue visibility and reduce the impact of sudden swings in customer ordering.
Traditional memory markets can be highly volatile. Customers often increase purchases when shortages are expected and reduce orders when inventory becomes excessive. Long-term commitments may create a more stable balance between supply and demand.
The agreements may also help Sandisk plan capital expenditure and production more efficiently. When management knows that future capacity is already committed, it can make manufacturing investments with greater confidence.
Investors should still examine the contract terms carefully. Total contract value does not necessarily equal guaranteed profit, and pricing formulas, purchase obligations and market conditions may affect the eventual economics.
Data Centers Become the Main Growth Engine
Sandisk’s data-center business generated approximately $2.98 billion in fourth-quarter revenue, more than twice the previous quarter’s level.
This rapid expansion shows how strongly AI infrastructure is changing the storage market.
AI discussions often focus on processors from companies such as Nvidia and AMD. Yet complete AI systems also require networking equipment, memory and vast quantities of storage.
Enterprise SSDs store model data and support the rapid movement of information between processors and computing systems. As AI inference expands, data centers may require more storage close to active workloads.
Inference is the process through which a trained AI model generates predictions, answers or other outputs. Large-scale inference can create continuous data demand rather than the temporary demand associated only with model training.
Sandisk is also working on newer flash technologies designed for AI workloads, including high-bandwidth flash. The objective is to provide greater storage capacity with performance characteristics suitable for increasingly data-intensive systems.
Why Sandisk Stock Fell After the Earnings Beat
Sandisk shares declined nearly 8% in extended trading even though both quarterly results and the company’s revenue guidance exceeded some analyst forecasts.
The negative reaction appears to reflect extremely high expectations.
Sandisk forecast fiscal first-quarter revenue of $10.3 billion to $10.8 billion. The midpoint was above the $10.47 billion average estimate cited by Reuters, but below the approximately $10.8 billion FactSet consensus reported by MarketWatch. Adjusted EPS guidance of $44 to $46 was above one estimate but only broadly aligned with other forecasts.
Different data providers can report different consensus figures because they include different groups of analysts or update estimates at different times.
More importantly, Sandisk stock had already risen almost 470% during 2026 before the earnings release. After such a large rally, investors may demand guidance that exceeds even the highest forecasts.
The decline does not necessarily indicate that the business is weakening. It may instead show that much of the expected storage boom was already reflected in the share price.
First-Quarter Guidance Still Points to Strong Growth
Sandisk’s revenue outlook of $10.3 billion to $10.8 billion implies continued sequential expansion from the $8.97 billion reported in Q4.
The company also expects adjusted earnings of $44 to $46 per share, compared with $39.25 in the latest quarter.
Those projections suggest that management expects pricing and demand to remain favorable.
The main concern is whether gross margins are approaching a peak. Memory manufacturers can report extraordinary profitability during severe supply shortages, but margins may eventually normalize when new production comes online.
Investors should monitor management’s pricing commentary, unit shipments and manufacturing-capacity plans. Revenue growth supported by both higher volumes and stable pricing would be more durable than growth dependent almost entirely on continuing price increases.
Share Buybacks Signal Management Confidence
Sandisk’s board authorized an additional $14 billion share-repurchase program, bringing its remaining authorization to approximately $15.5 billion.
A buyback allows a company to repurchase its own shares, potentially reducing the number outstanding and increasing earnings per share.
The authorization demonstrates confidence in Sandisk’s financial position and future cash generation. It may also provide support during periods of stock-market volatility.
However, the value created by a repurchase depends on the price paid. Buying shares at an attractive valuation can benefit remaining shareholders, while aggressive repurchases after a major stock rally may produce weaker returns.
Investors should therefore monitor actual repurchase activity rather than focusing only on the maximum authorization.
What Sandisk Investors Should Watch Next
The first important metric will be whether fiscal first-quarter revenue reaches the upper end of the $10.3 billion to $10.8 billion range.
Data-center revenue will remain central. Continued expansion would confirm that AI storage demand is providing more than a temporary boost.
Investors should also watch NAND pricing, gross margin and the share of production covered by long-term agreements. More committed supply could reduce volatility, but it must still generate attractive returns.
Sandisk’s upcoming investor day may provide additional detail about capacity, technology roadmaps and long-term financial targets.
The latest earnings show a company benefiting powerfully from the AI infrastructure cycle. The stock’s decline shows that investors are already expecting exceptional performance to continue.
