SanDisk (NASDAQ:SNDK | SNDK Price Prediction) and Micron Technology (NASDAQ:MU) both delivered blockbuster AI-driven memory quarters, then got swept up in a brutal mid-July correction as investors questioned whether storage demand has peaked. SanDisk, freshly spun off from Western Digital (NASDAQ:WDC) in February 2025, now sports a four-figure share price. Micron trades below $900 with real fabs and locked-in contracts behind it.
Datacenter Carries SanDisk. HBM Carries Micron.
SanDisk’s Q3 FY2026 revenue hit $5.95 billion, up 251% YoY, with non-GAAP EPS of $23.41 crushing the $14.66 consensus. The Datacenter segment grew 645% YoY, but Consumer slipped 10% sequentially, a small crack worth noting. CEO David Goeckeler called it a “fundamental inflection point” tied to a mix shift toward enterprise SSDs.
Micron ran bigger and broader. Q3 FY2026 revenue reached $41.46 billion, up 345.7% YoY, with GAAP gross margin of 84.6% and seven consecutive EPS beats. HBM4 is already in high-volume shipments for its lead AI customer, and Cloud Memory alone brought in $13.77 billion.
One Depends on a Partner. One Owns Its Fabs.
The structural gap is where the “dangerous” label sticks to SanDisk. It relies on the Kioxia Corporation Flash Ventures JV for manufacturing, sells commodity-prone NAND, and has only five multi-year New Business Model agreements signed so far. Micron, by contrast, is the only U.S.-based memory manufacturer, spent $7.83 billion on capex last quarter, and has billions locked in Strategic Customer Agreements.
| Lens | SanDisk | Micron |
| Core Product | NAND flash, HBF | DRAM, HBM4, NAND |
| Manufacturing | Kioxia JV dependence | Owned U.S. fabs |
| Trailing P/E | 60 | 22 |
| YTD Move | +581.5% | +229% |
SanDisk fell 28.85% in the past week to $1,617.70. Micron slipped 18.69% to $938.38. The larger drop tells you where fragility hides.
The Next Test Is Hyperscaler Capex
Both stocks live and die on cloud spending. Micron guided Q4 revenue to $50.0 billion with ~86% gross margin, an outlook backed by HBM4E ramping into calendar 2027. SanDisk projected $7.75B to $8.25B in Q4 revenue. I want to see whether SanDisk’s remaining NBM signings close and whether Consumer weakness spreads before I trust the run higher.
Why I Lean Toward Micron Right Now
If I had to hold one memory name through a demand wobble, it is Micron. Owned fabs, HBM leadership, and a 30% dividend increase earlier this year give me real downside support. SanDisk’s story is genuinely impressive, but a 60 trailing P/E, Kioxia dependency, and a young standalone track record leave me cautious. If you want turnaround-style upside and can stomach the volatility, SanDisk fits. For me, Micron’s asset base and contract book win the risk-adjusted call.
