The data centers theme covers Korean companies involved in building, powering, and cooling the facilities that store and process cloud and AI workloads, including server hardware, power equipment, and related infrastructure. Korean investors group these names together because demand for AI computing has pushed up spending on this physical infrastructure, linking firms across several industries under one narrative. Companies in this group are often sensitive to global cloud capital expenditure trends and to the pace of AI adoption.
