History
SK hynix produces and sells memory semiconductors, with products including DRAM, NAND storage, SSD and MCP, plus solutions for AI, server, mobile, PC, consumer-electronics and automotive uses, and positions itself as evolving from a traditional memory supplier into a "Full Stack AI Memory Creator." Its annual revenue rose from about ₩43.0 trillion in 2021 to ₩97.147 trillion in 2025, though not smoothly: it posted a ₩7.73 trillion operating loss in 2023 before operating profit reached ₩47.21 trillion in 2025. Current CEO Kwak Noh-Jung joined the company in 1994 and has served as President and CEO since 2022.
Industry position
SK hynix is among the leaders in a highly concentrated memory oligopoly. Per Morningstar, as of 2024 it held roughly 33% of the global DRAM market and about 21% of NAND, ranking top two in both. TrendForce data showed it surpassed Samsung in DRAM revenue for the first time in the first quarter of 2025, and Counterpoint reported it led DRAM for three consecutive quarters through the third quarter of 2025, with HBM about 40% of its DRAM sales. In high-bandwidth memory it is the market leader, with share estimates ranging from about 52.3% to about 61%. Its moat rests mainly on scale, process technology, customer validation and capital intensity, while Samsung and Micron pursue HBM4 and advanced nodes.
