The author explicitly references closing the P/E valuation gap with U.S.-based Micron, making MU the direct comparator. SK hynix's strong HBM share validates the entire HBM market, which benefits Micron as the other major HBM supplier.

The article's heading 'Can you say Nvidia?' directly ties SK hynix's HBM dominance to Nvidia's GPU demand. HBM is a critical component for Nvidia's AI accelerators, and SK hynix's leadership supports Nvidia's supply chain reliability and product roadmap.
Risk: Over-reliance on a single customer; any pivot away from HBM or supplier diversification could reduce NVDA's exposure to SK hynix's success.
