Total Raise and Record Scale

• Gross proceeds: Approximately $26.5 billion (177.9 million ADS × $149) .
• Initial target: SK Hynix initially aimed for up to $29.4 billion before adjusting down during bookbuilding amid pressure on the Seoul-listed stock .
• Historical significance: This is the largest foreign ADR listing in U.S. history, surpassing Alibaba's $21.8 billion debut in 2014 . It was also the second-biggest share sale globally in 2026 after SpaceX's $85.7 billion IPO .

Oversubscription: More Than Seven Times Covered

• The offering was more than seven times oversubscribed, according to Bloomberg and other sources .
• Reuters confirmed that orders had "covered its books multiple times" by July 8, leading to an early close of the bookbuild . One analysis estimated total orders reached roughly against the 177.9 million ADS on offer .

Cornerstone Investors: Up to $7 Billion

Three institutional investors collectively expressed interest in purchasing up to $7 billion of the ADRs, representing about 25% of the total offering :

• Baillie Gifford Overseas Limited – the UK-based long-term asset manager .
• Coatue Management – a prominent U.S. tech-focused hedge fund .
• Situational Awareness Partners LP – a hedge fund founded by former OpenAI researcher Leopold Aschenbrenner .

These commitments were disclosed in an SEC filing on July 6 and served as a strong anchor for the bookbuild . They were indications of interest, not final allocation amounts .

Ticker, Listing Date, and Lock-Up

• Ticker symbol: SKHY on the Nasdaq Global Select Market .
• Listing date: Pricing finalized July 10; ADR trading commenced July 10–11 .
• Lock-up period: A standard 90-day lock-up restricts existing shareholders and the company from selling additional shares .

Use of Proceeds: Capacity Expansion

All proceeds from the ADR offering are allocated to capacity expansion to meet AI-driven memory demand :

• Construction of the Yongin semiconductor cluster (new fabrication facilities).
• Investment in advanced packaging equipment.
• Introduction of extreme ultraviolet (EUV) lithography equipment, with a plan to invest about 11.9 trillion won in EUV equipment by end of 2027 .
• General memory chip production capacity expansion.

Key Risks and Analyst Concerns

• Valuation near a memory cycle peak: Multiple sources note that the listing arrives at a point when the memory chip cycle may be approaching a peak, raising concerns that investors could be buying at elevated valuations . SK Hynix's stock had rallied approximately 258% in 2026 before the listing .
• Seoul share price decline during bookbuilding: The Korean-listed stock (000660.KS) came under pressure during the ADR marketing period. The target was revised down from an initial ~$29.4 billion after pre-pricing pressure . The domestic share price fell roughly 2.5–3% during the bookbuilding phase .
• Narrow premium limits arbitrage: While the $149 ADR price is a ~3.1% premium to the Seoul close, some analysts flagged that the narrow spread could limit arbitrage and that the effective valuation leaves little room for error if memory demand softens .
