We are one of the world’s largest memory semiconductor companies and engage in the design, manufacture and sale of advanced memory semiconductors. In the DRAM market that includes HBM, we were ranked second globally based on revenue with a market share of 29.1% in the first quarter of 2026, according to market research conducted by IDC. In the HBM market, we were ranked first globally based on revenue with a market share of 56.4% in the first quarter of 2026, according to IDC. In addition, we were the second largest supplier of NAND flash memory based on revenue, with a worldwide market share of 18.5% in the first quarter of 2026, according to IDC.

Our memory products can be used in virtually all electronic devices, including graphics cards, personal computers (“PCs”), data center servers, mobile devices such as smartphones and tablets, and other consumer electronics products. We also conduct our foundry business through SK hynix system ic Inc. (“SK hynix system ic”) and SK keyfoundry Inc. (“SK keyfoundry”), our wholly-owned subsidiaries.

We sell a wide variety of DRAM and NAND flash memory products with various configuration options, architectures and performance characteristics tailored to meet application- and customer-specific needs. We believe that we are one of the world’s leading companies in developing DRAMs with advanced specifications, particularly those requiring higher density, faster data-processing speed and lower power consumption. We are continually developing higher-density DRAM modules, SSDs and other advanced DRAM and NAND flash memory products that are optimized for our customers’ specific applications. In recent years, we have substantially increased our sales of HBMs. HBMs are advanced memory semiconductors designed to deliver fast data transfers while using less power, making them especially useful in high-performance applications such as GPUs, AI and high-performance computing.
