SK Hynix $29.4B Nasdaq Listing: All You Need to Know About the ADR Debut, Structure, Underwriters, and Antitrust Lawsuit

Why SK Hynix Is Listing in the U.S.

The company plans to raise approximately 45.45 trillion won (roughly $29.4 billion) . Unlike many large IPOs where proceeds might go to existing shareholders, all of the money raised will go toward semiconductor production expansion. This includes funding advanced AI memory fabrication plants and EUV (extreme ultraviolet) tool orders to meet surging demand for high-bandwidth memory (HBM) chips used in AI applications . A second goal is to narrow the valuation gap between SK Hynix's South Korean listing and what the company believes its ADRs can command from U.S. investors .

The Antitrust Lawsuit Disclosed in the Filing

SK Hynix included the risk of a U.S. class-action antitrust lawsuit in its amended filing . The suit was filed on June 25, 2026, in the U.S. District Court for the Northern District of California by the law firms Bathaee Dunne LLP and Hagens Berman .

Who is involved?

• Defendants: Samsung Electronics, SK Hynix, and Micron Technology — the world's three largest memory chipmakers .
• Plaintiffs: 17 U.S. consumers and small businesses, seeking damages for allegedly inflated prices paid on DRAM-containing products .

What is the core allegation?

The plaintiffs claim the three companies conspired to artificially restrict DRAM supply and coordinate a production cut. Allegedly, they simultaneously pivoted production capacity toward higher-margin AI-focused HBM chips, thereby driving up DRAM prices . The complaint notes that these three companies account for virtually the entire global DRAM market .

What this means for investors
By including this lawsuit in its amended F-1 filing, SK Hynix has formally disclosed it as a risk factor for U.S. investors ahead of the July 10 debut . The case remains in early stages, and no judgment has been entered. It is also worth noting that a similar lawsuit against the same companies was dismissed by the Ninth Circuit in 2022 for lack of sufficient factual evidence .
