Micron slides 2% as rival SK Hynix plans US listing
Korean memory giant's $10B ADR offering intensifies competition in high-bandwidth AI chip market
Micron Technology shares fell 2.2% to $395.53 on Tuesday as South Korean rival SK Hynix moved closer to a US listing that would deepen competition in the rapidly growing market for artificial intelligence memory chips.
SK Hynix submitted a confidential filing to US securities regulators for an American Depositary Receipt listing, targeting a debut by the end of 2026, according to Bloomberg News. The Korean memory leader aims to raise between $6.7 billion and $10 billion through the offering, funds that will be primarily directed toward expanding high-bandwidth memory (HBM) production capacity and developing a new semiconductor cluster in Yongin, South Korea.
The listing would give SK Hynix, which currently controls approximately 62% of the global HBM market, direct access to US capital markets and potential inclusion in major indices like the Philadelphia Semiconductor Index. The company has already completed development of its next-generation HBM4 memory chips and showcased a 16-layer, 48GB version at CES 2026, with mass production scheduled to begin in the third quarter of 2026.
Micron, which has seen its shares surge more than 500% over the past year amid booming demand for AI-related memory products, trades at a forward price-to-earnings ratio of 7.63 times, significantly cheaper than many peers. Analysts maintain a consensus target price of $515.17, representing roughly 30% upside from current levels. Of the 43 analysts covering the stock, 38 rate it a buy or strong buy, while just two recommend selling.
Despite the bullish analyst sentiment, Micron faces intensifying competitive pressure as the industry race shifts to HBM4 technology. The three-way battle between SK Hynix, Micron, and Samsung Electronics for dominance in next-generation AI memory has intensified, with both SK Hynix and Samsung reportedly selected as sole suppliers of HBM4 for Nvidia's upcoming Vera Rubin AI accelerator platform.
Micron is not sitting idle. The company has indicated that its HBM4 chips are already pre-sold for 2026, and management has emphasized that the company is aggressively expanding HBM manufacturing capacity. Still, SK Hynix's ability to access deep US capital markets through a public listing could provide the Korean giant with additional resources to accelerate its HBM4 development and potentially extend its market leadership.
The competitive dynamics come as memory makers enjoy unprecedented demand from AI chipmakers like Nvidia, AMD, and Intel. HBM, which stacks memory chips vertically to achieve faster data transfer rates, has become essential for training and running large language models and other AI applications. The global HBM market is projected to grow from roughly $4 billion in 2023 to more than $30 billion by 2026, according to industry estimates.
Micron's current valuation discount reflects some investor concern about the company's ability to compete effectively against its larger Korean rivals. The stock trades at 8.2 times trailing revenue, compared to SK Hynix's private market valuation that analysts estimate at a premium multiple. Micron's profit margin of 41.5% and return on equity of 39.8% demonstrate strong fundamentals, but the company's market share in HBM remains significantly below SK Hynix's dominant position.
The US listing would mark a significant milestone for SK Hynix, which has historically relied on domestic and European capital markets. By establishing a direct US equity presence, the company could attract a broader base of institutional investors and potentially reduce its cost of capital for future investments in the capital-intensive semiconductor business.
For Micron investors, the development represents both a challenge and an opportunity. While increased competition could pressure pricing and market share in the HBM segment, the overall expansion of the AI memory market provides enough growth to support multiple successful competitors. The company's strong balance sheet, with enterprise value of roughly 12.8 times EBITDA, gives it financial flexibility to invest in capacity expansion and product development.
The next catalyst for Micron will likely be its quarterly earnings report, where investors will be watching for updates on HBM4 progress, customer wins, and pricing trends in the AI memory market. Until then, the stock may face headwinds as the market digests the implications of SK Hynix's planned US entry.
