[Alpha Biz= Kim Jisun] Seoul, October 1 – Doosan Group has emerged as a potential bidder for SK Siltron, a leading semiconductor wafer manufacturer, according to industry sources.



Reports indicate that Doosan Corporation is reviewing the acquisition of SK Inc.’s 70.6% stake in SK Siltron. The remaining 29.4% stake is held by SK Group Chairman Chey Tae-won.



This is not the first time acquisition rumors have surfaced. In April, Doosan dismissed similar reports as “groundless.” However, just six months later, the group appears to be revisiting the opportunity. Doosan is said to be identifying semiconductors, alongside SMRs (Small Modular Reactors) and robotics/AI, as its future growth pillars.



Valuation and Deal Structure

SK Siltron’s enterprise value is estimated at around KRW 5 trillion. With approximately KRW 3 trillion in debt, the equity value for SK Inc.’s 70.6% stake could be around KRW 1.5 trillion, depending on negotiations. Industry observers note that the ability of SK and Doosan to agree on valuation will be the key determinant of the deal.



Strategic Importance

SK Siltron is regarded as one of SK Group’s “crown jewel” subsidiaries, ranking third globally in 12-inch wafer market share. The company was put on the market as part of SK Group’s portfolio rebalancing strategy.



Private equity firms such as MBK Partners and Hahn & Company have previously explored bids for SK Siltron but failed to reach an agreement with SK on price.
