SK Hynix (000660.KS) Stock Surges 5% on SEC Filing for U.S. Listing

Key Highlights

• The memory chipmaker submitted a confidential filing to the SEC for U.S. ADR listing, with completion expected in 2026
• SK Hynix seeks to generate approximately $6.7 billion to $10 billion through the offering
• Funds will support AI infrastructure growth, including the Yongin HBM production hub and Indiana packaging plant
• CEO Kwak Noh-Jung announced at the annual meeting plans to accumulate over 100 trillion won in net cash for strategic growth initiatives
• Shares climbed more than 5% in Seoul trading on Wednesday; year-to-date gains exceed 60%

Shares of SK Hynix climbed more than 5% during Wednesday’s Seoul trading session following the company’s announcement that it submitted a confidential filing to the U.S. Securities and Exchange Commission for a prospective Wall Street debut. The memory chip manufacturer has posted approximately 60% gains year-to-date and witnessed a remarkable 274% surge throughout 2025.

The memory chip giant intends to introduce American Depositary Receipts on U.S. exchanges and targets completion by the end of 2026. Company officials stated that precise terms, including offering size and timeline, remain under consideration.

According to South Korean media outlets, the company aims to secure between 10 trillion won and 15 trillion won — approximately $6.7 billion to $10 billion based on present currency valuations.

SK Hynix initially disclosed its ambitions for a U.S. market debut in December of last year. This strategic initiative aims to raise substantial capital to support manufacturing capacity growth amid surging demand for artificial intelligence memory solutions.

The corporation stands as the global frontrunner in high-bandwidth memory chip production, supplying critical components for AI accelerators manufactured by partners including Nvidia. HBM demand has intensified dramatically, creating worldwide supply constraints and upward price momentum.

Capital Deployment Strategy Takes Shape

The capital generated through the offering will primarily finance the company’s HBM production complex in Yongin, South Korea, including its $15 billion investment there, along with its sophisticated packaging operation in Indiana. Management is also evaluating establishing an AI-focused investment division in Silicon Valley.

During Wednesday’s shareholder gathering, CEO Kwak Noh-Jung outlined plans to accumulate more than 100 trillion won in net cash reserves to support long-range strategic initiatives.

The company’s M15X manufacturing facility in Cheongju, South Korea, reached completion earlier than projected. Development work continues on both the Yongin complex and the Indiana site.

In correspondence to shareholders, management highlighted “unprecedented growth” throughout the memory sector, characterizing memory as “a key-value product that determines the performance of AI systems.”

Major Equipment Purchase Agreement

Merely 24 hours before announcing the SEC filing, SK Hynix revealed plans to acquire 11.95 trillion won ($7.97 billion) in cutting-edge semiconductor manufacturing equipment from ASML — representing one of the largest publicly disclosed transactions for such technology.

The synchronized announcement of both the ASML agreement and the SEC submission signals an aggressive strategy to cement its dominance in the HBM segment ahead of competitors Samsung and Micron.

Samsung continues efforts to reclaim market position in HBM production, while Micron has expanded its footprint as an American-based option in the AI memory sector.

SK Hynix indicated it will provide additional information once final terms of the U.S. listing are established, or within a six-month window following the original submission.

The company’s ADR program will utilize existing shares instead of issuing new equity, maintaining value for current stakeholders.
