Industry Analysis
SK Hynix’s narrowing tech gap with Micron isn’t just a market share shuffle—it’s resetting the DRAM/NAND innovation cadence. Its 1β-node DRAM output now rivals Micron’s, compressing the latter’s pricing power in HBM3E and LPDDR5X segments and forcing equipment vendors like Lam Research to accelerate EUV integration. Geopolitically, while U.S. export controls haven’t explicitly targeted SK Hynix, its Wuxi fab—producing nearly 20% of global DRAM—faces latent supply chain risk; any policy escalation would inflate compliance costs and destabilize customer commitments. Micron will likely counter with patent litigation or exclusive AI GPU memory deals with NVIDIA/AMD, avoiding price wars in this capital-intensive HBM era. Over the next 18 months, surging AI server demand will mask competitive tensions—but if SK Hynix fails to secure influence in HBM4 standardization, its current valuation premium may evaporate.
