Here’s what you need to know about SK Hynix’s IPO, which is said to be https://www.ft.com/content/33133a86-925e-4395-9f60-35e2a4052500?syn-25a6b1a6=1 the largest-ever U.S. stock listing by a foreign company. SK Hynix is a South Korean semiconductor company that makes memory chips—DRAM and NAND flash—that power the GPUs and CPUs that AI servers require, including those made by chip giant Nvidia. The company is headquartered in Icheon, South Korea, and was founded 43 years ago under another name: Hyundai Electronics. In 2001, the company rebranded to Hynix Semiconductor. In 2012, it was sold to Samsung competitor SK Group, and rebranded to its current name, SK Hynix. When it comes to high-bandwidth memory HBM , the type of memory needed for the most powerful AI servers, SK Hynix is the global leader, supplying 58% of HBM demand, according https://www.ig.com/en/news-and-trade-ideas/memory-chip-stocks-rally-2026-260708 to IG.com. Within the global DRAM market, SK Hynix ranked second in Q1 of 2026, with 29% market share, after Samsung’s 38%, according https://counterpointresearch.com/en/insights/global-dram-and-hbm-market-share to Counterpoint Research. Micron came in third place at 22%. Given the ongoing memory chip shortage due to AI companies’ insatiable demand for data center buildouts, it’s little surprise that both its revenue and its operating profit have been surging recently. For its fiscal 2025, SK Hynix posted revenue of 97.15 trillion won about $64.6 billion , up nearly 47% versus the year earlier, according https://www.koreajoongangdaily.com/business/sk-hynix-set-to-overtake-samsung-after-posting-record-331b-profit-in-2025/10112993 :~:text=SK%20hynix's%20Icheon%20headquarters%20in,boosted%20demand%20and%20pricing%20power. to the Korea JoongAng Daily. Its operating profit for the same period was 47.2 trillion won about $31.3 billion , up 101%. It’s important to note that SK Hynix’s U.S. market debut isn’t a traditional IPO. It’s not a first-time listing of its shares. SK Hynix has been publicly traded on the Korea Exchange stock market since 1996, when it was still called Hyundai Electronics. Today, the company trades on that market under the ticker 000660.KS. SK Hynix’s IPO today refers to its debut on a U.S. market. And that debut won’t actually allow investors to buy Korean shares in the company directly. Instead, SK Hynix’s U.S. IPO book-running managers, which include BofA Securities, Citigroup, Goldman Sachs, and J.P. Morgan, will sell American depositary shares ADS . ADS are essentially a wrapper for foreign stocks trading under foreign currencies. When you buy one ADS of SK Hynix on U.S. markets, it represents one-tenth of a common share traded on the Korean stock market. So, 10 ADS shares of SK Hynix equate to one foreign share of SK Hynix. SK Hynix’s American depositary shares are expected to debut today, Friday, July 10, 2026. SK Hynix’s American depositary shares will trade on the Nasdaq Global Select Market under the stock ticker “SKHY.” The company says https://www.skhynix.com/ir/UI-FR-IR12 T1 view/?seq=6809 one ADS of SKHY will have an initial public offering price of $149. The U.S. IPO will offer 177,900,000 American depositary shares of SKHY.
