SK hynix released third-quarter results that set records on both the top and bottom line, and its stock responded immediately in Seoul trading on Wednesday, October 28, 2026. Shares rose 5.67% from Tuesday's close to 1.417 million won in early Seoul trading on Wednesday.

The results release put quarterly revenue at 104.62 trillion won, roughly $78.9 billion, with the company recording record figures for both revenue and earnings. The print matters beyond a single ticker: memory chips are foundational components in everything from PCs and smartphones to AI data centers, and the global memory market is concentrated among a small group of producers, so a record quarter from one of its largest suppliers serves as a hard-data reference point for conditions across the semiconductor memory sector.

SK hynix, an affiliate of South Korean conglomerate SK Group, is one of the world's largest manufacturers of memory semiconductors, producing DRAM and NAND flash storage. The company is also a major supplier of high-bandwidth memory (HBM), a type of chip used in artificial intelligence data centers, and competes globally with Samsung Electronics and Micron Technology. Its shares trade on the Korea Exchange in Seoul. Those two rivals sit alongside SK hynix at the top of the memory business, and each reports results on its own quarterly calendar, giving readers follow-on checkpoints on how supply, demand, and pricing are developing across the industry.

What to watch from here is easy to track: how the stock trades through the rest of Wednesday's session on the Korea Exchange, the fuller detail SK hynix provides alongside its results, and the upcoming quarterly disclosures from Samsung Electronics and Micron Technology, which will add the next set of hard numbers to the picture this record quarter opens.
