One-sentence summary
Compares three storage makers' latest quarters: SanDisk NAND at $11.03B, Seagate HDD at $4.23B, Micron DRAM/HBM at $54.23B, showing scale and margin divergence across three memory tiers in the AI cycle.
What Is Compared
- SanDisk: NAND flash, fiscal Q1 2027 (reported October 29, 2026).
- Seagate: HDD, fiscal Q1 2027 (ended October 2, 2026).
- Micron: DRAM and HBM, fiscal Q4 2026 (ended September 3, 2026).
Key Parameters
| Dimension | SanDisk (NAND) | Seagate (HDD) | Micron (DRAM/HBM) |
|---|---|---|---|
| Latest-quarter revenue | $11.03B | $4.233B | $54.23B |
| Diluted EPS | $52.60 | $7.59 | $32.87 |

| Net income | — | $1.761B | $37.70B |
| Next-quarter guide | $12.2-12.6B | — | — |
| Core driver | NAND price surge | Nearline HDD | HBM4 ramp |
Key Differences
Micron is the largest by revenue (DRAM/HBM pulled by AI accelerator demand), SanDisk's ~85% gross margin reflects acute NAND shortage, and Seagate benefits from nearline HDD datacenter expansion. All ride the AI storage supercycle, but each benefits from a different segment with different elasticity.
