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. We have focused our sales and marketing activities in recent years on expanding our base of long-term strategic customers. We believe that our expertise and know-how in producing advanced memory semiconductors, strong long-term relationships with our key customers and state-of-the-art global production facilities in key strategic locations provide us with sustainable competitive advantages that will continue to differentiate us from our competitors and enable us to take advantage of attractive growth opportunities. We believe that we are a global leader in the HBM market with advanced production know-how and development of specific configurations that meet our customers’ demands. Our customers seek HBM suppliers with whom they can better align their own product development efforts and their strict quality standards often require HBM manufacturers to comply with rigorous testing and approval processes. We believe that our strengths in HBM, server DRAM and eSSD enable us to mitigate the risks associated with the cyclicality of the memory semiconductor market. We own and operate wafer fabrication facilities (“fabs”) in Icheon and Cheongju, Korea and Wuxi and Dalian, China. We also own and operate assembly and testing facilities for back-end processing of our products in Icheon and Cheongju, Korea and Chongqing, China. As part of our efforts to reduce unit manufacturing costs, improve manufacturing yields and enhance our profitability, we periodically phase out the operations of our older fabs or upgrade them to implement more advanced processing technologies. In addition to regular maintenance and enhancement of existing fabs, in October 2025, we opened the cleanroom of a new extension fab called “M15X” in Cheongju, which we plan to utilize to further increase our production capacity of next-generation DRAMs such as HBM. We began wafer input at the M15X in the first quarter of 2026 and expect to gradually ramp up our production volume. As part of our efforts to ensure our long-term competitiveness, we have also announced initiatives to construct an integrated industrial complex in Yongin, Korea for our next generation of fabs and research and development facilities. We began construction of our first fab at the Yongin complex in February 2025 with the phase 1 cleanroom of the first fab expected to open in the first quarter of 2027. We are currently constructing an advanced packaging plant called “P&T7” in Cheongju and expect to complete construction by the end of 2027. In December 2024, we also announced plans to build an advanced packaging plant in Indiana, United States, and expect to commence operations in the second half of 2028. In order to maintain our technological leadership, as well as to access new markets for our products, we engage in strategic initiatives, including making investments and acquisitions, from time to time. In October 2020, we agreed to acquire the NAND flash memory and storage business of Intel Corporation (“Intel”) (the “Intel NAND Business Acquisition”), including the NAND flash memory manufacturing facility in Dalian, China, NAND flash memory and SSD-related intellectual property and research and development personnel. As consideration for the Intel NAND Business Acquisition, we paid US$6.6 billion in December 2021 and US$2.2 billion in March 2025. We created a subsidiary in the United States to operate the acquired business under the brand name “Solidigm.” We also selectively acquire minority equity positions in other industry players to further strengthen our business relationships and acquire complementary businesses that we believe can further strengthen our leading position in the industry. Our principal executive offices are located in Korea.
