SanDisk has delivered one of the most dramatic transformations in the semiconductor market, and now even a previously skeptical analyst is acknowledging that the business is becoming stronger. Analyst Gary Alexander upgraded SanDisk to Neutral, arguing that the company’s margin gap versus competitors is narrowing while management is using a severely constrained NAND market to lock major customers into multi-year agreements at favorable prices. Yet the rating stops conspicuously short of Buy, creating a fascinating tension around the SanDisk stock forecast 2026: the company’s fundamentals may be improving at extraordinary speed, but after SNDK’s enormous rally, how much of that improvement is already reflected in the share price?
SanDisk’s latest financial results show why the upgrade cannot simply be dismissed as enthusiasm following a rising stock. Fiscal fourth-quarter revenue reached $8.97 billion, up 51% sequentially, with management saying approximately one-third of that increase came from higher volume and two-thirds from higher pricing. Datacenter revenue more than doubled sequentially to $2.98 billion, while full-year revenue surged 175% to $20.25 billion. Even more striking, SanDisk’s fiscal-year gross margin reached approximately 71.5%, compared with just 30.1% in fiscal 2025.
Those are not small improvements. They represent a fundamental change in the economics of the business.
But the NAND industry has fooled investors before.
SanDisk Is Finally Showing the Pricing Power Investors Wanted to See
NAND flash has historically been an unforgiving business. Producers spend enormous amounts building manufacturing capacity, supply frequently overshoots demand and prices can collapse when customers suddenly find themselves holding too much inventory. The industry’s cyclicality has made it difficult for manufacturers to sustain attractive margins and even harder for investors to determine what a “normal” year of earnings should look like.

SanDisk’s latest quarter looked nothing like that old model. Revenue increased 51% sequentially, and roughly two-thirds of the improvement came from pricing rather than volume, demonstrating how aggressively market conditions have shifted in favor of suppliers. Fiscal fourth-quarter datacenter revenue jumped 103% sequentially, while Edge revenue increased 48%. The only major category moving backward was Consumer, where revenue declined 32% sequentially.
That mix shift matters. SanDisk is becoming increasingly exposed to higher-value enterprise and AI-related workloads instead of depending primarily on consumer flash products. Datacenter revenue for fiscal 2026 reached $5.15 billion, up 437% from the previous year, while Edge revenue climbed 195% to $12.16 billion.
The company is therefore benefiting from two forces simultaneously: dramatically better NAND pricing and a move toward customers willing to pay more for high-performance storage.
AI is helping drive both.
AI’s Next Bottleneck May Be Storage, Not Just Compute
The first phase of the AI investment boom was dominated by GPUs and high-bandwidth memory because training enormous models required extraordinary computing power. But as those models move into production and begin generating vast numbers of tokens through inference, the storage problem becomes increasingly important.
AI systems create, retrieve and process enormous quantities of data. Models need rapid access to datasets, vector databases, inference caches and other information that cannot remain permanently inside expensive high-bandwidth memory. That creates an expanding role for enterprise flash storage, where SanDisk believes it has a substantial opportunity.
At its August Investor Day, SanDisk said the total available market for enterprise data-center flash could reach 1.2 zettabytes by 2030 as AI inference becomes increasingly storage intensive. The company also highlighted its High Bandwidth Flash, or HBF, technology as a potential solution for emerging AI workloads while outlining new NAND products designed to increase density and performance more efficiently.
This gives SanDisk a different AI thesis from Micron. Micron is heavily exposed to DRAM and HBM sitting close to the processor. SanDisk’s opportunity centers more directly on NAND flash and the enormous amount of persistent storage required as AI infrastructure scales.
If AI inference expands the way the industry expects, the quantity of data needing fast, power-efficient storage could become staggering.
But SanDisk is not merely betting on demand.
It is attempting to change how that demand is contracted.
Multi-Year Deals Could Finally Make NAND Less Brutally Cyclical
The most interesting part of Gary Alexander’s upgrade may be SanDisk’s improving deal visibility. The company has been signing what it calls New Business Model agreements, or NBMs, designed to replace some of the uncertainty that historically defined the NAND market with longer-term customer commitments, minimum financial guarantees and structured pricing mechanisms.
At its August Investor Day, SanDisk said it had signed NBMs with eight customers representing approximately 50% of fiscal 2027 bits and roughly two-thirds of fiscal 2028 bits. Management argues these agreements can improve revenue and cash-flow visibility while allowing production capacity to be aligned more closely with actual customer demand.
The latest quarterly results show that momentum continuing. SanDisk said it had signed five additional agreements since announcing five NBMs during its April earnings call, including three agreements with new customers and two expansions of existing deals.
This matters because the NAND industry’s historical problem was not a lack of long-term demand. The world has consistently needed more digital storage. The problem was that manufacturers repeatedly struggled to match supply growth with demand growth, creating destructive pricing cycles.
Long-term agreements cannot eliminate that risk, but they can reduce it. If suppliers know more precisely how many bits customers require several years in advance—and if those customers provide minimum financial commitments—the temptation to build capacity blindly becomes smaller.
That could make SanDisk’s earnings considerably more durable.
And management is setting extraordinarily ambitious financial targets around that idea.
SanDisk’s Long-Term Margin Target Is Almost Hard to Believe
At its 2026 Investor Day, SanDisk outlined a financial framework for fiscal 2028 through fiscal 2030 that would have looked almost impossible during weaker NAND cycles. The company expects revenue to grow at a mid-to-high-teens rate, with non-GAAP gross margins around 80%, operating margins around 75% and adjusted free-cash-flow margins of approximately 50%. SanDisk also said it expects to return 100% of excess cash to shareholders after funding the business.
Those targets explain why investors have become so enthusiastic.
A semiconductor manufacturer producing 80% gross margins and returning excess cash to shareholders would look fundamentally different from the low-margin commodity-storage business investors remember.
SanDisk is already demonstrating significant progress. Fiscal 2026 gross margin reached roughly 71.5%, up more than 40 percentage points from the prior year, while annual net income reached $11.43 billion. The company also expanded its share-repurchase authorization by another $14 billion, leaving approximately $15.5 billion available.
But this is also where the investment thesis becomes dangerous.
Extraordinary margins attract competition, and NAND remains an industry populated by formidable global rivals.
The Bull Case Gets Harder When Everyone Knows Supply Is Scarce
SanDisk currently benefits from severely constrained market conditions, and Alexander specifically highlighted management’s ability to use that environment to secure favorable multi-year deals. That is smart execution, but investors must distinguish between improvements created by company strategy and those created by an exceptionally strong pricing cycle.
Samsung, SK hynix and Micron are not going to ignore attractive NAND economics forever. If profitability remains extraordinarily high, producers have an incentive to expand supply, improve technology and compete aggressively for high-value data-center customers. As additional capacity reaches the market, pricing power can weaken.
There is also a demand-concentration risk. SanDisk’s increasing exposure to data centers is highly attractive while hyperscalers are spending aggressively on AI infrastructure, but that same exposure could become a vulnerability if capital expenditure eventually slows. Earlier analysis of SNDK highlighted precisely this concern: greater dependence on data-center customers can make the company more exposed to a future hyperscaler demand cliff.
That does not mean such a cliff is imminent. SanDisk’s own outlook points in the opposite direction, and its multi-year agreements provide substantially better visibility than traditional spot-market demand.
It does mean that investors buying after a spectacular rally need more than strong conditions today.
They need those conditions to remain strong tomorrow.
October 29 Could Become the Next Major Test for SNDK Stock
SanDisk’s next major catalyst is already on the calendar. The company is scheduled to report fiscal first-quarter 2027 results on October 29, giving investors their next opportunity to test whether extraordinary pricing and data-center demand are continuing.
Management previously guided for first-quarter revenue between $10.3 billion and $10.8 billion, with non-GAAP diluted earnings of $44 to $46 per share. If SanDisk reaches the midpoint, revenue would rise substantially again from the already record-setting $8.97 billion reported in the fourth quarter.
The details will matter even more than the headline number. Investors should watch how much growth continues to come from pricing, whether data-center demand maintains its momentum, how gross margins progress toward management’s long-term framework and whether additional customers sign multi-year NBMs.
If those indicators remain strong, the argument that SanDisk’s earnings power has structurally changed becomes more convincing.
If pricing begins weakening, however, investors may quickly rediscover why memory stocks historically received discounted valuations.
The SanDisk Stock Forecast 2026 Is Now a Battle Between Execution and Expectations
Gary Alexander’s move to Neutral captures the dilemma surrounding SanDisk unusually well. The business has improved enough that a deeply bearish position becomes harder to defend. Pricing power is stronger, margins have exploded, data-center revenue is growing at extraordinary rates and management has secured multi-year agreements that could reduce the volatility traditionally associated with NAND.
Yet Neutral rather than Buy also acknowledges the other half of the story: investors have noticed.
SNDK closed October 5 around $1,704, after a staggering run that has dramatically raised the expectations embedded in the stock. Current analyst estimates remain widely dispersed, illustrating just how difficult the company is to value while NAND economics are changing so quickly.
The bullish scenario is powerful. AI inference makes data centers increasingly storage intensive, NAND supply remains disciplined, long-term contracts stabilize pricing and SanDisk gradually delivers something close to the financial model it presented at Investor Day. Under that scenario, today’s enormous profits could prove much more durable than skeptics expect.
The bearish scenario is equally straightforward. AI infrastructure spending eventually slows, competitors add supply, NAND pricing normalizes and margins retreat from today’s exceptional levels. If that happens after investors have priced SNDK for structural transformation, the downside could be severe.
That is why October 29 matters.
SanDisk no longer needs to prove that it can benefit from the AI boom. Its numbers have already done that.
Now it has to prove something much harder: that this isn’t merely another spectacular NAND cycle destined to end like all the others.
The stock has already priced in a transformation. The next earnings report begins the test of whether that transformation is permanent.
