Kumho Electric shares jumped 19.17% to 8,890 won by 10:18 a.m. on the 21st, briefly reaching the daily upper limit of 9,690 won, as investors responded to renewed expectations for an 895 trillion won Honam semiconductor cluster involving Samsung Electronics and SK hynix. Kumho E&C rose 4.03% to 16,280 won after gaining nearly 16% intraday to 18,200 won, supported by its announcement of a Samsung Electronics contract to build a 23,588-square-meter Flakt Group HVAC plant in Gwangju for completion in February 2028. The Jeonnam-Gwangju Integrated Metropolitan City is reviewing honorary road names using Samsung Electronics and SK hynix, whose planned cluster around the former Gwangju military airport site would initially comprise four fabs, with at least two more under consideration by 2040. The fully operational cluster is projected to generate about 100 trillion won in annual semiconductor sales and roughly 20,000 direct jobs. Kumho Electric's rally remains driven mainly by regional and policy expectations, as no direct connection between its lighting and LED businesses and the semiconductor cluster has been confirmed.
