SanDisk (SNDK) Stock Jumps 61% Year-Over-Year as AI Infrastructure Fuels Storage Boom

Key Highlights

• Q2 fiscal 2026 revenue reached $3.03 billion, marking a 61% year-over-year increase
• Gross margin expanded dramatically from 29.8% to 50.9% quarter-over-quarter
• Datacenter segment revenue surged 64% sequentially on AI infrastructure spending
• Q3 fiscal 2026 revenue outlook set at $4.40B–$4.80B, with projected EPS between $12–$14
• Analyst consensus stands at Moderate Buy with 24 analysts averaging a $594.48 price target

Following its separation from Western Digital, SanDisk has emerged as an independent flash memory specialist. This corporate restructuring has provided market participants with greater transparency into its pure-play NAND storage operations.

Sandisk Corporation, SNDK

The most recent quarterly performance demonstrates robust momentum. For fiscal Q2 2026, SanDisk delivered $3.03 billion in revenue. This figure represents a 31% sequential increase and a 61% year-over-year improvement.

Profitability metrics showed even more dramatic improvement. The company’s gross margin expanded from 29.8% to 50.9% between consecutive quarters. This substantial margin expansion reflects improving NAND pricing dynamics alongside a strategic pivot toward premium product offerings.

Datacenter operations emerged as the primary growth catalyst. SanDisk’s datacenter revenue jumped 64% sequentially, fueled by demand from AI infrastructure deployments, hyperscale cloud providers, and semi-custom storage solutions.

The product mix shift toward enterprise and datacenter SSDs carries significant profitability implications. These higher-margin offerings contrast sharply with consumer-grade storage products, explaining much of the margin improvement.

Forward Outlook Signals Sustained Momentum

Management’s guidance reinforces the positive trajectory. For Q3 fiscal 2026, the company projects revenue between $4.40 billion and $4.80 billion. Non-GAAP diluted earnings per share are expected to land between $12.00 and $14.00.

These projections indicate that demand pressures remain robust rather than moderating. The growth trajectory appears to be intensifying compared to the January quarter performance.

Despite recent momentum, trailing 12-month earnings per share remains at -7.6. This negative figure illustrates the severity of the preceding NAND market downturn, though current conditions have obviously transformed.

Analyst sentiment remains constructive on the stock. MarketBeat data shows 24 analysts providing coverage. The distribution includes 15 buy ratings, 2 strong buy ratings, 6 hold ratings, and 1 sell rating, resulting in a Moderate Buy consensus rating.

The mean 12-month price target of $594.48 sits modestly above recent trading levels near $572.50. This suggests relatively modest upside potential based on current Street expectations.

Current Valuation Embeds Optimistic Assumptions

The company’s market capitalization recently approached $42.9 billion. This represents a substantial valuation for an organization still emerging from a cyclical trough.

Market participants are evidently pricing in sustained improvement rather than temporary recovery. The AI infrastructure narrative provides a more compelling thesis than traditional NAND recovery patterns.

Memory semiconductor stocks exhibit pronounced cyclicality. The same operational leverage that rapidly expands margins can compress them equally fast when pricing weakens or capacity additions increase.

The central question centers on whether this upturn represents a standard cyclical recovery or a structural shift. Persistent datacenter demand linked to AI infrastructure buildouts could extend the margin expansion cycle beyond historical patterns.

The Q3 guidance provides the most current demand signal. Revenue projections approaching $4.80 billion indicate management sees no near-term demand deterioration from major customers.

Bottom Line

SanDisk presents as a business with genuine operational momentum, expanding profitability, and improved strategic clarity following the corporate separation. The enterprise is clearly capitalizing on AI-related storage demand alongside favorable industry dynamics. However, following its substantial rally, the stock appears fairly valued as a quality cyclical business with institutional support rather than an undervalued opportunity.
