AI Storage Demand Drives Sandisk Growth as Elevated Expectations Weigh on Shares

Strong AI Demand Continues, but Guidance Falls Short of Elevated Expectations

Sandisk (SNDK) reported another quarter of exceptional financial performance, supported by booming demand for AI infrastructure and enterprise storage. Revenue, earnings, and gross margins all exceeded Wall Street expectations as hyperscale data center customers continued expanding storage capacity.

Despite those results, shares declined sharply after management's first-quarter outlook came in modestly below the market's elevated expectations, highlighting how difficult it has become for AI leaders to continue surpassing increasingly optimistic forecasts.

Key Points

• Sandisk reported fourth-quarter revenue of $8.97 billion and adjusted EPS of $39.25, both above Wall Street expectations.
• AI-driven data center demand more than doubled sequentially, while gross margin expanded to a record 84.6%.
• Shares fell after first-quarter revenue guidance came in slightly below elevated market expectations despite continued strong industry fundamentals.

What Happened?

Sandisk delivered one of its strongest quarters since becoming an independent company, with fiscal fourth-quarter revenue reaching $8.97 billion, comfortably ahead of analyst expectations near $8.5 billion. Adjusted earnings per share of $39.25 also exceeded consensus estimates.

The results reflected exceptionally strong demand across the AI infrastructure market. Data center revenue climbed to $2.98 billion during the quarter, increasing more than 100% sequentially as hyperscale customers expanded storage deployments for artificial intelligence workloads.

Overall revenue growth was driven by both higher shipment volumes and stronger pricing, while gross margin improved to a record 84.6%, reflecting favorable pricing dynamics and an increasingly profitable product mix.

For the full fiscal year, Sandisk generated more than $20 billion in revenue, up 175% from the prior year as demand for NAND flash storage continued accelerating.

Why Did Sandisk Stock Fall?

Although the quarterly results exceeded expectations, investors focused on management's outlook for the upcoming quarter.

Sandisk projected first-quarter revenue between $10.3 billion and $10.8 billion. While this still represented another sequential increase, the midpoint came in slightly below Wall Street expectations, which had moved closer to the upper end of that range following months of exceptional performance.

Management also guided gross margins between 83% and 85%, implying relatively stable profitability but falling short of investors hoping for another meaningful expansion.

The reaction reflected the extremely high expectations surrounding AI-related semiconductor companies rather than any significant deterioration in Sandisk's business. Shares had already risen more than 450% year to date before the earnings release, leaving little room for anything short of another major upside surprise.

Several analysts noted that the results remained fundamentally strong, describing the market reaction as largely an expectations reset rather than a change in the long-term outlook.

Why Does AI Storage Demand Remain Important?

Management continued to describe AI infrastructure as a powerful long-term growth driver for the business.

Data center revenue now represents a much larger portion of Sandisk's business than a year ago, supported by enterprise solid-state drives and expanding storage requirements for AI training and inference workloads. The company said demand continues to outpace supply, with storage bits expected to remain on allocation beyond calendar 2027.

Sandisk also expanded its long-term supply agreements, announcing five additional agreements since April. Across eight agreements with six customers, the company now has approximately $93.9 billion in committed minimum contract value spanning an average duration of more than four years.

Executives said these agreements provide greater revenue visibility while helping reduce the historical boom-and-bust cycles common in the memory industry. Pricing protections built into the contracts are also intended to support profitability while allowing participation if market pricing continues rising.

Management expects the NAND market to continue expanding rapidly, with data center applications representing an increasing share of industry demand as AI adoption grows across cloud infrastructure.

What It Means for Investors

Sandisk's quarterly results illustrated how quickly expectations have risen across the AI infrastructure sector.

The company continued delivering exceptional revenue growth, record profitability, expanding data center demand, and stronger long-term customer commitments. However, after an extraordinary rally in the stock, investors were looking for guidance that significantly exceeded already elevated forecasts.

Management emphasized that industry fundamentals remain favorable, with demand continuing to outpace supply and long-term customer agreements providing greater visibility into future revenue. Investors will likely continue watching pricing trends, gross margins, enterprise SSD demand, and execution on long-term supply agreements as indicators of whether the current AI storage cycle can continue.

Conclusion

Sandisk reported another standout quarter as AI-driven demand for enterprise storage supported record revenue, expanding margins, and stronger profitability. Data center revenue more than doubled sequentially, while long-term customer agreements continued strengthening visibility into future demand.

Despite those positives, shares declined after first-quarter guidance fell just short of elevated market expectations following the stock's remarkable rally. The reaction underscored how investors remain focused not only on strong execution but also on whether AI beneficiaries can continue exceeding increasingly ambitious expectations.
