Why it matters

The strategic read

Moves SK Telecom's operating data centers, projects under construction and submarine-cable assets into a dedicated infrastructure platform with more than KRW 3T of signed outside capital. The structure gives KKR and the IMM consortium a combined 49% stake while SK Telecom retains control, creating a funded 318 MW base for Ulsan, Guro and further AI data-center expansion alongside SK Hyper's separate gigawatt-scale development mandate.
