- The board approved the investment on Friday, Aug. 7, splitting about 35.2 trillion won for Yongin Y2 (DRAM/HBM) and 19.1 trillion won for Cheongju M17 (NAND).
- SK hynix set firm construction milestones with M17 groundbreaking planned for February 2027 and its first cleanroom targeted for December 2028, and Y2 groundbreaking planned for July 2027 with a first cleanroom expected in June 2029.
- The company said it will stage equipment installation to follow customer demand and will review additional shareholder-return measures in the third quarter of 2026.
- Investors reacted negatively, sending SK hynix shares down about 5% as market participants weighed heavy near-term capital spending against forecasted memory shortages.
- SK hynix framed the move as a response to industry forecasts of strong memory growth and export-control constraints at its China sites, while analysts note the decision raises execution and timing risks as Samsung and Micron also expand capacity.
