Cost Structure
Capital Expenditure for Fabs
The largest cost for SK Hynix is fab CAPEX: in 2025 the company raised capital spending to nearly 30 trillion won to expand HBM (high-bandwidth memory) and 1c nm DRAM capacity, creating multi-billion-dollar build-and-equip bills that drive high fixed costs and steep depreciation charges across future income statements.
Research and Development Expenses
SK Hynix invests heavily in R&D to advance DRAM, NAND and next-gen memory, covering salaries for thousands of researchers and the costs of experimental pilot lines; in 2024 R&D expenses were about 9.2 trillion KRW (roughly $7.0B), representing a high double-digit share of revenue in peak innovation years.
Raw Material and Utility Costs
High-purity silicon wafers, specialty chemicals, and electricity drive major costs for SK Hynix; in 2024 the company reported energy-related expenses forming roughly 8–10% of COGS and raw materials about 20–25%, with wafer costs rising ~12% year-on-year in 2023–24. Fluctuating input prices and 2022–25 inflation spikes compress margins, since fabs consume gigawatt-scale power and electricity price moves materially affect operating profit.
Labor and Talent Acquisition
SK Hynix faces rising labor costs as fabs need highly skilled engineers; in 2024 R&D and personnel spend was about KRW 6.3 trillion (≈USD 4.6B), reflecting intense competition in South Korea and globally.
High salaries, benefits, and bonuses are essential to retain staff for complex fab ops, making labor a growing share of operating expenses—personnel costs rose ~8% year-on-year in 2024.
- 2024 personnel/R&D spend: KRW 6.3T (≈USD 4.6B)
- YoY personnel cost increase: ~8% in 2024
- Competitive hiring pressure: domestic and global engineering markets
Advanced Packaging and Assembly
As HBM (high-bandwidth memory) grows in SK Hynix’s mix, back-end costs rise: TSV (through-silicon via) formation and MR-MUF molding materials push packaging costs ~30–50% higher for premium AI memory versus commodity DRAM, adding roughly $8–15 per 8‑GB HBM stack in 2025 production runs.
- TSV formation: +30% cost vs standard
- MR-MUF materials: +40–60% per unit
- Premium AI memory: $8–15 extra per 8‑GB stack (2025)
Heavy CAPEX, rising wafer & HBM costs squeeze margins despite high R&D spend
Fab CAPEX (~30T KRW in 2025) and depreciation, high R&D (9.2T KRW in 2024) and personnel (6.3T KRW in 2024) dominate costs; raw materials (20–25% of COGS) and energy (≈8–10% of COGS) plus rising wafer (+12% YoY) and packaging premiums for HBM (+$8–15 per 8‑GB) compress margins.
| Item | 2024–25 |
|---|---|
| CAPEX | ~30T KRW (2025) |
| R&D | 9.2T KRW (2024) |
| Personnel | 6.3T KRW (2024) |

| Energy | 8–10% of COGS |
| Materials | 20–25% of COGS |
| HBM premium | $8–15 per 8‑GB (2025) |
Revenue Streams
HBM Sales for AI Accelerators
HBM sales for AI accelerators became SK Hynix’s top growth engine, doubling year-on-year to reach about KRW 8.4 trillion in 2025 H2, and now represent roughly 35–40% of the company’s DRAM revenue.
Standard DRAM for Servers and PCs
The sale of commodity DDR4 and DDR5 modules remains a core revenue stream for SK Hynix, generating roughly 18–22% of 2024 consolidated NAND/DRAM revenue mix and delivering steady cash flow despite cyclicality; global DDR5 adoption in servers raised average selling prices ~12% year-on-year in 2024, offsetting DRAM spot volatility.
Enterprise and Client SSDs
SK Hynix earns substantial revenue from NAND-based storage, led by high-capacity enterprise SSDs for data centers; NAND product sales accounted for about 45% of 2024 revenue, with enterprise SSD demand rising as hyperscalers expand AI clusters. The 2021 acquisition of Intel’s NAND business (Solidigm) boosted SK Hynix’s eSSD share—company reported Solidigm-related sales of roughly $3.2 billion in 2024—driven by AI-era storage growth projected at ~25% CAGR through 2028.
Mobile Memory Solutions
Mobile Memory Solutions: SK Hynix sells low-power DRAM (LPDDR) and mobile NAND to smartphone OEMs; in 2024 mobile memory accounted for about 28% of SK Hynix revenue, driven by high-volume shipments and ASPs rising with higher-density parts.
The rise of AI-enabled phones pushed demand for 8GB+ LPDDR5/LPDDR5X and 256GB+ UFS/NAND, increasing average configuration value and supporting margin expansion in 2024–2025.
