What the company does
SK hynix is a memory chipmaker headquartered in Icheon, South Korea. According to its annual report, the legal entity was set up in 1949 as Kukdo Construction and renamed Hyundai Electronics in 1983, when it entered the chip business. It became Hynix Semiconductor in 2001 and took its current name in 2012 after joining the SK Group. Its main products are DRAM and NAND flash, and it also runs a small foundry business.
How it makes money
The company reports one segment, semiconductors, and all of its revenue comes from memory such as DRAM and NAND. Consolidated revenue grew from 32.8 trillion won in 2023 to 66.2 trillion won in 2024 and 97.1 trillion won in 2025. Its 2025 report says growing demand for AI inference lifted not only HBM but also conventional DRAM, while high-capacity enterprise SSDs for AI data centers drove NAND demand.
Why markets watch it
Memory prices swing hard, so SK hynix results are read as a signal of where the chip cycle is heading. As HBM for AI accelerators has grown in importance, the stock often reacts to Nvidia earnings and Big Tech capital spending plans. Along with Samsung Electronics it is one of the heaviest KOSPI stocks, so foreign buying and selling also moves the index and the won.
