Memory giant SK Hynix is nearing a US listing, bringing one of the world's largest HBM suppliers to American capital markets.

In June 2026, South Korean memory giant SK Hynix is accelerating its entry into Wall Street. The undisputed leader in the global high-bandwidth memory (HBM) market plans to list on Nasdaq by issuing American Depositary Receipts (ADRs) under the ticker symbol "SKHY," marking one of the largest U.S. listings by a foreign company in recent years.

**Company Overview**

SK Hynix was established in 1983 as Hyundai Electronics Industries Co., Ltd. The company spun off from Hyundai Group in 2001 as Hynix Semiconductor, then took its current name following acquisition by SK Group in 2012. Headquartered in Icheon, South Korea, the company is led by CEO Kwak Noh-jung and specializes in memory semiconductors, including DRAM, NAND Flash, and MCP.

The company endured significant challenges in its early history. In 2002, debt crises forced consideration of a sale to Micron Technology, a deal that ultimately fell through. Years of pressure from falling global memory chip prices culminated in an operating loss of approximately 7.73 trillion won in 2023. However, the subsequent AI boom has transformed the company into a leading global supplier of AI memory.

Unlike Samsung Electronics, which spans consumer electronics, logic chips, and memory chips, SK Hynix concentrates exclusively on memory semiconductors. This focused business model allows the company to capture more direct benefits from surging demand for AI-driven HBM. SK Hynix positioned its HBM technology ahead of the AI demand wave, establishing market leadership through products such as HBM2E. The company now supplies memory products for AI chips to Nvidia, Google, and other major clients. Its partnership with Nvidia has evolved from component procurement into deep strategic integration.

**Listing Timeline and Structure**

SK Hynix's U.S. listing plans are progressing faster than anticipated. The company confidentially submitted a registration statement for an ADR initial public offering to the U.S. SEC in March 2026. On June 24, SK Hynix announced plans to issue depositary receipts worth up to 45.45 trillion won, approximately $29.4 billion. Bank of America, Citigroup, Goldman Sachs, and JPMorgan serve as lead underwriters.

According to the company's announcement, the depositary receipts are expected to begin trading on Nasdaq on July 10, 2026. Each ADR is priced at 255,500 won. The final amount raised may be adjusted following the bookbuilding process. SK Hynix stated that proceeds will fund construction of Phase 1 of the Yongin Semiconductor Cluster wafer fab, the Cheongju P&T7 advanced packaging plant, and equipment investments including EUV lithography machines.

SK Group Chairman Chey Tae-won stated that U.S. listing will expand the shareholder base beyond South Korea and increase exposure to American and international investors. CEO Kwak Noh-jung remarked at the annual shareholders' meeting that the company hopes to have its value re-evaluated in the U.S. market alongside major global technology firms.

**Financial Performance**

SK Hynix's shares have surged dramatically in 2026. Since the beginning of the year, the stock price has climbed more than 300%, with gains exceeding 800% over the past twelve months. During intraday trading on June 22, the stock briefly rose over 6% to 2.95 million KRW, pushing total market capitalization past 2,082 trillion KRW and momentarily overtaking Samsung Electronics to become South Korea's most valuable listed company on the KOSPI. This marked the first time since November 2000 that Samsung Electronics lost its position as the country's most valuable company.

In the first quarter of 2026, SK Hynix reported revenue of 52.58 trillion KRW, a year-on-year increase of 198%, and operating profit of 37.61 trillion KRW, up 405% year-on-year. The company achieved an operating margin of 72%, exceeding Nvidia's 65% margin during the same period. Market consensus expects second-quarter operating profit to range between 62 trillion and 65 trillion KRW, with some brokerages forecasting results above 68 trillion KRW.

For the full year 2025, SK Hynix reported revenue of 97.15 trillion KRW, up 47% year-on-year, with operating profit rising 101% to 47.21 trillion KRW. This marked the first time the company's annual operating profit surpassed Samsung Electronics. HBM sales more than doubled year-on-year, growing to comprise 42% of total revenue.

**Competitive Position in HBM**

High-bandwidth memory is a critical technology for AI infrastructure, consisting of multiple stacked DRAM layers placed in close proximity to AI chips. This proximity enables the high-speed data transfer essential for large language models and other demanding AI workloads.

SK Hynix dominates the global HBM market. As of the first quarter of 2026, Counterpoint Research data showed SK Hynix held a 58% global market share, with Samsung Electronics and Micron each accounting for 21%. Samsung is actively catching up, having begun mass production of HBM4 in February to supply Nvidia. On June 5, Nvidia CEO Jensen Huang confirmed that SK Hynix, Samsung, and Micron have all qualified and begun HBM4 production to supply Nvidia's next-generation Vera Rubin platform. SK Hynix supplies over 60% of Nvidia's HBM requirements and has secured over two-thirds of the company's HBM supply orders for Vera Rubin.

As AI chip power consumption approaches 1,000W and stacked layers continue to increase, thermal management has become the focal point of HBM technological competition. The three major manufacturers are launching differentiated cooling solutions including iHBM, HPB, and TSV liquid cooling.

**Investment Options**

**Direct ADR Purchase (Coming Soon)**

Following the July 10 listing, U.S. investors will be able to trade SK Hynix ADRs directly in USD through U.S. brokerage accounts. Inclusion in the Philadelphia Semiconductor Index (SOX) is expected to follow, attracting passive fund allocations.

**Korean Stock Market Trading**

SK Hynix currently trades on the Korea Exchange under ticker 000660.KS. Direct purchase of Korean stocks requires enabling Korean stock trading permissions or using sub-brokerage services, which presents operational complexity. Investors can also access SK Hynix-related ETFs and leveraged products on the Korean market.

**U.S. Semiconductor ETFs**

Several U.S. ETFs currently hold SK Hynix positions. The Roundhill Memory ETF (DRAM), launched April 2, 2026, is the first "pure-play memory ETF," with over 50% of portfolio revenue derived from HBM-related businesses. It includes hard-to-access companies such as SK Hynix, Samsung Electronics, and Kioxia.

The Franklin FTSE South Korea ETF (FLKR) tracks the FTSE South Korea Index with highly concentrated holdings in South Korean large-cap stocks. SK Hynix is the largest holding at 31.33%, with SK Hynix and Samsung Electronics combined accounting for over 51% of assets.

The iShares MSCI South Korea ETF (EWY) is the largest South Korea ETF in the U.S. market, with SK Hynix as its top holding at nearly 30% and Samsung Electronics exceeding 20%, for a combined 48% of fund assets. Since 2026, this ETF has gained over 90%.
