SK Hynix (SKHY) is now trading in the U.S. with ADRs, entering a market long dominated in memory by Micron Technology (MU). Current data show SK Hynix posting significantly higher operating margins and stronger recent revenue growth than Micron, even as Micron trades at a higher valuation multiple. That combination creates a clear valuation disconnect between two core DRAM and HBM suppliers.
History across semiconductor cycles shows that such margin‑valuation mismatches between close peers can persist for extended periods. Episodes involving Micron, Samsung Electronics, SK Hynix, Broadcom, and TSMC indicate that any repricing has typically unfolded gradually over quarters or years, often clustering around earnings, technology updates, or capital‑allocation announcements. The SK Hynix ADR listing mainly increases visibility and access for U.S. investors to this existing gap rather than guaranteeing a specific short‑term trading outcome.
Within the memory oligopoly, SK Hynix and Micron remain central vehicles for exposure to DRAM and high‑bandwidth memory demand tied to data‑center and AI spending. The current configuration features SK Hynix with higher profitability and a dominant HBM share, while Micron commands the richer equity valuation despite lower revenue. This setup aligns with prior semiconductor episodes where expectations, listing venue, liquidity, and perceived quality have temporarily outweighed near‑term earnings strength in determining relative multiples.
