SK Group has moved from reducing its portfolio to reallocating capital as its three-year restructuring nears completion. The group’s consolidated subsidiaries fell to 524 at the end of June from 634 a year earlier, after 110 were streamlined during the first half. SK Inc. agreed to sell its 70.6% stake in SK Siltron to Doosan for approximately 2.3 trillion won ($1.7 billion), while SK Ecoplant will absorb SK Eco Engineering. At the same time, SK Telecom is separating its data center and submarine cable operations into SK Horizon, selling a 37% stake to KKR and an IMM consortium for 1.88 trillion won ($1.4 billion) and planning a 1.2 trillion-won ($875 million) share issue. The process is expected to secure 3.08 trillion won ($2.2 billion) for expansion. SK Horizon is projected to increase capacity from 137MW to 318MW, including a 100MW Ulsan data center scheduled to begin operations in 2027 for Amazon. SK’s longer-term AIDC (artificial intelligence data center) plan targets 5GW of phased construction from 2029, followed by an additional 10GW after 2035. Similar external-capital-backed consolidation is under way in renewable energy, while an SK Group CEO seminar around October is expected to clarify the post-restructuring strategy. The effort also reflects Chairman Chey Tae-won’s designation of artificial intelligence as a future growth axis and seeks to reduce the financial burden of capital-intensive projects while preserving growth momentum.
