Is $SNDK Back? Investor Day Recap

Summary
SanDisk's investor day argues the memory cycle has structurally changed, with long-term contracts, floor pricing, and 80% gross margins even in the downside being the proof. The market implication is a more bullish NAND/HBF setup, but the contracts remain untested against the next downturn and new supply in 2027.
  • Q4 revenue was $8.97B (+51% QoQ), non-GAAP gross margin was 84.6%, and EPS was $39.25 vs. guidance of $30-$33.
  • Contract book locks in 50% of FY27 and two-thirds of FY28 bits with minimum guarantees; 10 agreements across 8 customers, including 3 hyperscalers, with $93.9B minimum revenue at floor prices.
  • Management guides FY28-30 revenue growth in the mid-to-high teens in line with bit growth, ~80% non-GAAP gross margin, 75% operating margin, 5% opex, and ~50% adjusted FCF margin.
  • Analysts already model $48.9B FY27 and $58.3B FY28 revenue; extending management's CAGR to FY30 yields ~$79B revenue and ~$40B annual FCF vs. a $227B market cap.
  • SanDisk says BiCS output per wafer can grow ~27% a year, but it will ship mid-to-high teens to avoid oversupplying the market; most NAND growth through 2027 comes from upgrading existing fabs.
  • HBF (NAND stacked like HBM) taped out its first die, with customer samples in 2027; the benchmark showed four HBF GPUs matching eight HBM GPUs, and HBF revenue is modeled at zero in the FY30 outlook.

SanDisk's own investor day guidance is the article's core: floor-priced contracts secure $93.9B of minimum revenue, downside gross margin is still ~80%, and management models ~50% adjusted FCF margin.
SanDisk's own investor day guidance is the article's core: floor-priced contracts secure $93.9B of minimum revenue, downside gross margin is still ~80%, and management models ~50% adjusted FCF margin. This supports bullish re-rating of SNDK as a disciplined NAND supplier. Risk: Historical memory crashes led customers to renege on LTAs; the new floor-price contracts have not yet been tested in a downturn, and new capacity arrives in 2027.

The article's NAND-supply-constraint and pricing-power thesis, plus the observation that 'HBM took off' and ate DRAM production and pushed up regular DRAM prices, directly maps to Micron's memory expo
The article's NAND-supply-constraint and pricing-power thesis, plus the observation that 'HBM took off' and ate DRAM production and pushed up regular DRAM prices, directly maps to Micron's memory exposure across NAND and DRAM. Risk: If 2023-style oversupply returns or HBF ramps enough to disrupt HBM demand, Micron could face the same LTA-breakdown/price-crash cycle the article warns about.
