Why did SanDisk stock crash after Q3 2026 earnings?

SanDisk (SNDK) fell ~8% after hours despite crushing Q3 FY2026 estimates (EPS $23.41 vs $14.62 est., revenue $5.95B vs $4.68B est.) due to six factors: (1) valuation gravity after a +3,300% 12-month rally, (2) consumer segment missed by 37%, (3) new multi-year contract model uncertainty, (4) Q4 guidance implied deceleration, (5) gross margin sustainability questions at 78.4%, and (6) institutional profit-taking.

Which AI storage stock has the best upside in 2026?

Based on analyst consensus targets as of May 2026: Micron (MU) has the highest absolute upside with a Street-high target of $1,000 (DA Davidson) driven by HBM dominance. Seagate (STX) has a Rosenblatt target of $1,000 driven by HAMR technology. Western Digital (WDC) has a Rosenblatt target of $500. SanDisk (SNDK) consensus is ~$1,200-1,400 after its +3,300% rally. Pure Storage (PSTG) consensus is ~$91 (+40% upside from ~$71).

What is the NAND flash market forecast for 2026?

The global NAND flash market is forecast to reach $147 billion in 2026, up +112% year-over-year, driven by AI data center demand, on-device AI storage requirements, and a structural supply shortage. The NAND supercycle is expected to continue through 2028 as AI model training and inference workloads require exponentially more storage capacity.

How does Micron's HBM compare to Samsung and SK Hynix?

As of Q2 FY2026, Micron has achieved HBM3E qualification with NVIDIA and AMD, with HBM capacity sold out through end of 2026. SK Hynix remains the dominant HBM supplier with ~50% market share. Samsung has faced yield challenges with HBM3E but is ramping production. The HBM market is forecast to grow from $35B in 2025 to $100B in 2028.
