SK Hynix, the South Korean memory chip giant, completed a $28 billion share sale in the US that was oversubscribed seven times, with $196 billion in investor demand. The offering involved 17.79 million common shares structured as 177.9 million ADRs at a 10:1 ratio. Cornerstone investors, including Baillie Gifford Overseas, Coatue Management, and Situational Awareness Partners, indicated interest of up to $7 billion collectively. SK Hynix’s shares have climbed roughly 260% year-to-date. The marketing campaign kicked off around July 6-7, 2026, with pricing expected shortly after and trading set to begin around July 10-11. Proceeds from the offering are earmarked for expanding production capacity and purchasing advanced ASML EUV lithography equipment. SK Hynix manufactures high-bandwidth memory (HBM), the specialized chips that sit inside NVIDIA’s data center GPUs and allow them to process massive datasets for AI workloads, and is one of only three companies capable of producing HBM at scale, alongside Samsung and Micron.
