Target
SSP is a semiconductor equipment maker whose core product is ball-mount equipment that places solder balls connecting chips to substrates in packaging, with a reported ~60% domestic market share; it also makes EMI shielding equipment, camera-module equipment and factory automation systems, with overseas sales above 60% of revenue.
Deal rationale
Keistone Partners, named preferred bidder with an MOU in April 2026, acquired 100% of SSP from LX Investment and others for about KRW 400bn on 31 July 2026, funded from undrawn capital in its Blind Fund No. 5 and new Blind Fund No. 6. Edaily reported LX Investment had bought SSP in 2022 for about KRW 180bn through a project fund (with M Capital, MG Saemaul Geumgo as a major LP) and recovered more than double its principal in about three years; for Keistone it marked its first semiconductor-equipment deal after ClassCard and Semo Company.
