Bottom Line
The Big-Three's $40-50B combined legacy exit creates a structural cycle where eight followers step in — with potential multiple re-rating for Hana Micron, Simmtech, and Daeduck.
Reading depth
- 1. Sizing the Markets the Big-Three Are ExitingThe Big Three are exiting a $40~50B footprint of 5~15% margin markets to reallocate capacity toward 50~70% margin HBM.Jump to section
- 2. Why the Big-Three Are Exiting — A Quantitative ReadReallocating the same wafer capacity to HBM and high-density DDR5 yields a business 5~10x more profitable, making the exit quantitatively rational.Jump to section
- 3. Followers' Revenue and Operating Profit (Primary-Source Verified)How much followers benefit from the vacated markets depends on their capacity build-out and utilization recovery.Jump to section
- 4. Re-rating — A Quantitative ReadFollowers' re-rating range hinges on whether a 2026 full-year operating-profit consensus exists and whether it is realized.Jump to section
- 5. Bringing It Together — Markets Vacated, Markets CapturedThis note assigns no buy/sell view or arbitrary probabilities and offers only a verified, fact-based multiple comparison.Jump to section
- Appendix — What Does 'Big-Three Leaving' Mean from a Process Perspective?The Big Three leaving means node upgrades, new HBM fabs, new packaging capacity, and staged legacy-fab EOL happening at once, with capacity itself the near-term bottleneck.Jump to section

Aggregating 'DDR4 + LPDDR4X + auto/industrial + Crucial consumer SSD' gives a combined exited-market footprint of ~$40~50B. The exact 'big-three sub-product breakdown' is not in public filings, hence the range, but operating margins in those segments were typically 5~15% versus 50~70%+ for HBM/SOCAMM2/cHBM (SK hynix 1Q26 quarterly OPM 71.5%).
