SK Hynix’s valuation paradox exposes structural tensions in the AI memory market. Technologically, HBM3E and upcoming HBM4 are accelerating demand for advanced packaging, TSV, and CoWoS ecosystems—granting TSMC and Taiwan, China outsized pricing power. Without deeper vertical integration or secured foundry capacity, SK Hynix risks yield and delivery bottlenecks. Geopolitically, while the U.S.-ROK semiconductor alliance offers short-term export tailwinds, tightening U.S. tech controls on China force SK Hynix into a high-wire act between its Xi’an operations and global client strategy, with compliance costs already eroding margins.
