What happened

SK hynix held a groundbreaking ceremony for its P&T7 advanced packaging facility in Cheongju, with an investment of trillions of KRW. The facility is dedicated to manufacturing AI memory products like HBM, with the WT line scheduled for completion by Oct 2027 and the WLP line by Feb 2028. Neutral: This long-term capacity expansion plan supports future HBM supply but has no immediate impact on current trading dynamics.
