SK Group has aborted the sale of SK Siltron – the world’s third‑largest wafer maker – just before the final contract signing. A deal with Doosan Semiconductor was set for May 28, 2026, but surging semiconductor demand and the strategic value of in‑house wafer capacity caused SK to reverse course.

SK Siltron forms a critical backend synergy with SK Hynix. With the industry entering a supercycle, holding wafer production became essential for SK’s AI‑focused strategy. SK Group Chairman Chey Tae‑won has launched a “semiconductor speed war,” aiming to double wafer capacity within five years.
The original plan was to sell SK’s 70.6% stake (51% direct + 19.6% via TRS). Chey personally holds another 29.4% , which would have required separate negotiations. With the sale halted, SK Siltron’s ~5 trillion won ($3.3B) valuation will be reassessed upward.
