SK Hynix hits record $26.5B US IPO as memory chip demand surges

SK Hynix, one of the world's largest memory chip manufacturers, has closed a historic $26.5 billion US initial public offering, marking the largest-ever US market debut by a foreign company and signaling explosive investor appetite for semiconductor firms riding the AI boom.

The Record-Breaking Deal#

The South Korean company sold 177.9 million American depositary shares at $149 each on Friday, July 10th, surpassing Alibaba's previous record of $25 billion in 2014. The pricing structure allowed US investors to purchase stakes at roughly one-tenth the cost of full shares traded in Seoul. Trading commenced immediately under the temporary ticker SKHYV, with regular trading beginning Monday under the permanent ticker SKHY. Early momentum was strong, with shares opening at a 14% premium to their IPO price and continuing to climb throughout the day.

The oversubscription was extraordinary—demand reportedly exceeded available shares by more than sevenfold, despite SK Hynix pricing its US offering at a 2.7% premium to its home market average.

Breaking Through the Korea Discount#

The reception stands in sharp contrast to how Korean companies have traditionally been valued. The "Korea Discount" refers to a long-standing gap where South Korean firms trade at lower multiples than global competitors, typically attributed to concerns around corporate governance, limited shareholder returns, regulatory uncertainty, and geopolitical tensions with North Korea.

SK Hynix's performance suggests this company has transcended that stigma entirely. The driver is straightforward: SK Hynix manufactures high-bandwidth memory (HBM), a critical component in AI accelerator chips. With demand for AI infrastructure soaring, the company has become indispensable to major players like Nvidia, fundamentally shifting investor calculus around its valuation.

Capital Deployment and Manufacturing Plans#

The company intends to deploy the capital across three initiatives: construction of a new manufacturing facility in South Korea to address the global memory shortage created by AI adoption, a new packaging plant in the country, and acquisition of EUV lithography scanners—the advanced machinery required to produce next-generation chips.

Notably, the capital plan conspicuously omits any new US manufacturing facility, even as geopolitical pressures mount.
