Samsung SDI closed at ₩515,000 on the 24th, up 7.74%, after disclosing plans to sell approximately 5% of its Samsung Display stake for about ₩4.45 trillion, or $3.2 billion. Ownership will decline from 15.2% to 10.2% after the transaction scheduled for the 27th. The company has not specified how it will use the proceeds, but investors and analysts expect the funds to support capital investment in the SynergyCells battery plant in New Carlisle, Indiana, and the expansion of North American energy storage system (ESS) capacity. The planned conversion of SynergyCells into a wholly owned subsidiary would allow Samsung SDI to recognize 100% of its battery profits as net income attributable to controlling shareholders. Samsung SDI’s gain contrasted with declines in Samsung Electronics and other major Samsung Group affiliates, while L&F and POSCO Future M rose 16.36% and 10.33%, respectively, as expectations for battery investment spread across the sector.
