Doosan Group signed a share purchase agreement to acquire SK Group’s 70.6% stake in semiconductor wafer maker SK Siltron for 2.3 trillion won, with the deal disclosed on July 31. The sale does not include SK Group Chairman Chey Tae-won’s separate 29.4% personal stake. The transaction gives Doosan a semiconductor wafer business, adding a key front-end manufacturing material to its existing semiconductor-related operations. For SK, the disposal is part of a broader portfolio reshaping aimed at securing funds for future investments. SK Siltron is South Korea’s only semiconductor wafer manufacturer, making the deal a significant move in the country’s chip supply chain. Whether Doosan will seek to acquire Chey’s remaining personal holding has not been included in this agreement.
