0. Executive Summary
| Key Question | Answer |
|---|---|
| Is the valuation expensive? | Forward PE 13.3x (at $647) / 15.5x (at $750), sitting at the 33rd percentile of its 5-year history (low); but PS 6.0x is at the 100th percentile (most expensive ever) -- the valuation contradiction reflects the market's skepticism that peak margins can persist |
| Are the fundamentals strong? | Latest fiscal Q2 FY26 gross margin hit 74.4% (all-time high), EPS $12.07, OCF $20.31B -- all exceeding the 2018 cycle peak |
| Cycle peak or mid-cycle? | Data suggests cycle peak (GM > 2018 historical top of 60.6%); but the narrative (HBM/AI/no new fabs until 2027) implies further runway |
| Takeaway | GARP signal is valid but approaching cycle peak territory |
1. Business Overview
One of the global Big Three in NAND + DRAM (alongside Samsung and SK Hynix).
Revenue mix (estimated for 2026 H1):
- DRAM ~70% (including HBM3E/HBM4, a critical companion to AI chips)
- NAND ~30%
- HBM accounts for 25%+ of DRAM revenue and continues to grow
Key customers: NVIDIA / AMD / Apple / Microsoft / Samsung / all major cloud providers -- heavily concentrated in AI data centers.

2.2 TTM Sequence (Key Inflection Points)
| Report Date | Price | TTM EPS | Fwd EPS | Fwd PE | Gross Margin | Rev YoY |
|---|---|---|---|---|---|---|
| 2024-03-21 | $109 | -$7.48 | $2.84 | 38.7x | 18.5% | -37% |
| 2024-10-04 | $102 | +$0.59 | $2.80 | 36.5x | 22.4% | +57% |

| 2026-03-19 | $444 | +$25.94 | $48.28 | 9.2x | 74.4% | +73% |
Since turning profitable in December 2024, gross margin has accelerated from 38% to 56% to 74%.
3. Cycle Positioning (The Critical Question)
Historical Cycle Peaks vs. Troughs
| Cycle | Peak (GM) | Trough (GM) |
|---|---|---|
| 2010-2016 | 33.7% (2014-12) | -10.3% (2016) |
| 2017-2019 | 60.6% (2018-Q3) | -10.5% (2019) |
| 2020-2023 | 47.2% (2022-Q2) | -32.7% (2023-Q2) |
| 2024-Present | 74.4% (2026-Q2)? | TBD |
Comparison with the 2018 Cycle Peak
| Date | Gross Margin | Quarterly EPS | Price | Next 12M |
|---|---|---|---|---|
| 2018-05-31 (pre-Q3 peak) | 60.6% | +$3.10 | $57 | -23% |
| 2018-08-30 (FY18) | 58.9% | FY18 EPS $11.51 | $42 (post-report) | +5% |
| 2026-02-26 (Current) | 74.4% | +$12.07 | $444 (report day) -> $750 (current) | ?? |
Core tension: Current gross margin of 74.4% already exceeds the 2018 all-time peak of 60.6%.
4. Multi-Dimensional Valuation
4.1 MU Historical Percentile Ranking
| Metric | Current | P25 | P50 | P75 | Max | Current Percentile |
|---|---|---|---|---|---|---|
| Forward PE (at $647) | 13.3 | 6.2 | 13.0 | 18.8 | 110.2 | 33% (low) |
| Forward PE (at $750) | 15.5 | 6.2 | 13.0 | 18.8 | 110.2 | 45% (mid) |
| TTM PE | 17.1 | 8.2 | 15.6 | 23.1 | 173.3 | 69% |
| PS TTM | 6.0 | 1.7 | 2.2 | 3.4 | 6.0 | 100% (most expensive) |
Core contradiction: Forward PE is low + PS is at an all-time high. The market does not believe peak margins will persist.
4.2 Peer Comparison (Calendar Q1 2026 Data)
| Ticker | Fwd PE | Gross Margin | PS TTM |
|---|---|---|---|
| MU | 13.4 | 74.4% | 8.8 |
| SNDK | 65.0 | 50.9% | 14.5 |
| WDC | 24.5 | 50.2% | 10.0 |
| STX | 73.7 | 46.5% | 10.5 |
| INTC | -- (loss) | 39.4% | 5.4 |
MU has the highest gross margin but the lowest PE -- a significant valuation scissors gap.
If PE were to converge to SNDK's 65x level, the implied price would be $3,124 (theoretical ceiling). If it converged to WDC's 24.5x level, the implied price would be $1,182 (+83%).
