Shares surged +3.8% to $747.69 in after-hours trading on March 18, defying a 1.48% S&P 500 decline, after SanDisk formalized multi-year NAND flash supply contracts with data center customers building AI infrastructure. The stock has rocketed roughly 21% in just one week, and the deeper question is whether locked-in contracts justify a valuation that already prices in years of perfect execution.
• The Deals Give SanDisk Something Memory Companies Rarely Get: Predictable Revenue
CEO David Goeckeler has said the company is moving away from traditional quarterly pricing toward long-term multi-year contracts with customers to ensure predictable demand at attractive pricing.
Demand visibility now stretches through 2028, with capacity reportedly fully booked under long-term hyperscaler deals. For a company that posted $7.36 billion in fiscal 2025 revenue, analysts project the narrative could reach $13.3 billion in revenue and $3.1 billion in earnings by 2028 — roughly doubling the business in three years.
• A Historic Shortage Gives SanDisk Enormous Pricing Power — For Now
NAND flash contract prices are expected to rise 55–60% quarter-over-quarter in Q1 2026 , and SanDisk's average selling price per gigabyte jumped in the mid-30% range last quarter.
Enterprise SSD revenues leapt 64% sequentially , with the company guiding Q3 earnings of $12–$14 per share — far above the consensus estimate of $9.43. When demand outstrips supply this severely, sellers set the terms.
• Being "Sold Out" Sounds Great Until the Cycle Turns
Concentrating exposure in data center and AI workloads helps pricing when supply stays tight, but it also ties results closely to a small group of very large buyers.
If hyperscalers over-order and demand normalizes, SanDisk's added capacity and long-term contracts could weigh on margins. Memory is notoriously cyclical, and competitors like Micron, Samsung, and SK Hynix are investing aggressively in advanced NAND.
• The Valuation Already Bakes In a Best-Case Scenario
Shares have surged over 550% in the twelve months since the Western Digital spinoff.
The average analyst 12-month price target sits at $515.44 — implying ~28% downside from today's price.
Stretched AI demand assumptions and reliance on aggressive 2027 earnings estimates could unwind quickly if hyperscaler orders or data center spending plans soften. Investors aren't just buying today's shortage — they're betting it persists for years.
