Sandisk Corporation

Business description

Sandisk Corporation (SNDK) is a pure-play NAND flash memory developer and manufacturer serving consumer, edge, and data center applications. The company was spun off from Western Digital Corporation on February 21, 2025. Unlike most major memory makers, SNDK only manufactures NAND memory and related devices — not DRAM — making its results highly correlated with NAND prices. SNDK manufactures NAND wafers via a longstanding joint venture with Kioxia across multiple facilities in Japan, with evenly split costs and output. The company disaggregates sales across three end markets: Data Center (25%), Edge (62%), and Consumer (14%).

Key financials

• Price: USD 1,354.82 (07/17/2026)
• 12-Mo Target: USD 2,852.00
• Market Cap: ~USD 209B
• CFRA Rating: Buy (Initiated June 25, 2026)
• H-Score: 68
• Non-GAAP Gross Margin: 78.4% (Q3 FY26)
• Non-GAAP Operating Margin: ~74.0% (Q4 FY26 guided)
• Debt: Zero debt as of Q3 FY26
• Share Buyback: $6B program announced

Competitive moat

• Pure-Play NAND Focus: As the only pure-play NAND manufacturer, SNDK's results are directly tied to the NAND supercycle, offering leveraged exposure to AI-driven storage demand.
• Hyperscaler Long-Term Supply Agreements (NBMs): Five NBMs signed year-to-date through April 30, 2026, covering ~1/3 of expected FY27 bit shipments, with $42B RPO (incl. $11B in enforceable financial guarantees). These feature combined fixed/variable pricing with minimum revenue commitments — a structural improvement over historical spot-market cyclicality.
• Kioxia JV Supply Pact: Extended the Yokkaichi JV supply agreement through December 31, 2034, ensuring long-term manufacturing capacity.
• High-Bandwidth Flash (HBF) optionality: Novel NAND-based AI inference memory targeting DRAM-like bandwidth at much lower cost; die design by CYE26, full solution by mid-CY27. Partnership with SK hynix on HBF development.
• Strategic Nanya Investment: $972M investment in DRAM-maker Nanya Technology mitigates crucial DRAM supply bottleneck for high-performance SSDs.
• Zero debt and $3.74B cash provide significant strategic flexibility and buyback capacity.

Recent developments

• Explosive Revenue Growth: Q3 FY26 revenue grew 251% Y/Y despite flat unit volumes, driven by skyrocketing NAND prices. Data Center revenue surged 645% Y/Y to $1.47B (25% of total sales, up from 12% in Q3 FY25).
• Hyperscaler NBM Momentum: Five long-term supply agreements signed with hyperscalers — dubbed "New Business Model" (NBM) — covering ~1/3 of expected FY27 bit shipments. Management expects 50%+ of shipments under such agreements as more deals close. $42B RPO exiting Q3.
• AI Inference and KV NAND Tailwind: Jensen Huang introduced KV NAND (all-NAND key value cache) at CES 2026. SNDK preliminarily estimates incremental NAND bit demand of 75-100 exabytes in FY27 and 150-200 exabytes in FY28 from AI inference architectures.
• "Stargate" QLC eSSD: New data center-focused QLC product (codenamed "Stargate") set to begin shipping in Q4, boosting differentiated enterprise SSD mix.
• Zero Debt Deleveraging: Paid down remaining $650M term loan in Q3, exiting with zero debt. Announced $6B share repurchase program expected to expand rapidly.
• NAND Supply Tightness: Material new greenfield capacity not expected until 2028; existing node transitions only provide 15-20% annual supply increases; Samsung/SK Hynix/Micron maintaining NAND supply cuts.

Investment risks / red flags

• NAND Price Reversal: Any reversal of elevated NAND prices from weakening demand or supply increases would severely impact revenue and margins. Current margins (70%+ non-GAAP gross) viewed as above normalized levels (~40%).
• HBF Adoption Uncertainty: High-bandwidth flash remains unproven in production AI architectures; failure to insert HBF into next-gen computing designs would remove a key long-term growth catalyst.
• China Exposure: 32% of FY25 sales from China; geopolitical and local competition risks (YMTC).
• Japan Operations Risk: Joint manufacturing facilities in Japan exposed to natural disaster and operational risks (Yokkaichi).
• Limited Operating History: Spun off only in February 2025; limited track record as independent entity makes valuation benchmarks more speculative.
• Valuation: Stock at $1,355 trades at 15.5x CFRA's FY26 EPS estimate with a 25% discount to peer average — reflects above-normalized margin assumption.

H-Score signals

• TBI multi factor score: 68 (07/20/2026)
• Moderate score reflecting strong momentum and value but offset by cyclical risks and elevated margin assumptions.
