The memory upswing: SK hynix 80%, Micron 81%, Samsung DS 72% operating margin in the latest quarter
Q1 2024 – Q3 2026
- Calculated operating margin = operating income ÷ revenue for each quarter; Samsung uses its DS division’s sales and operating profit (memory plus foundry and System LSI).
- Calculated ≈US$: KRW revenue at one approximate monthly rate (Federal Reserve G.5, Oct 2026) for every quarter, so the revenue lines show volume changes, not exchange-rate moves.
- Calculated Quarters are calendar quarters; Micron’s fiscal quarters (ending about a month earlier or later) are placed in the calendar quarter in which most of their days fall.
