Taesung raises $51.4M convertible bond to fund copper foil, glass substrate push
What's the deal? Korean equipment maker TaesungDealroom has a profile for this one. Try Dealroom → has issued a US$58.7M (roughly $51.4 million) post-IPO convertible bond to expand its composite copper foil and glass substrate businesses. Nine Korean asset managers — including SP, Artman, TimefolioDealroom has a profile for this one. Try Dealroom →, and GVA — participated in the private placement, announced on November 5.
What's the endgame? Taesung is moving beyond its core printed circuit board (PCB) wet-process equipment business into materials and next-generation packaging. Of the proceeds, US$33.5M goes to production facilities for composite copper foil and glass substrates, with US$25.2M for raw materials and R&D.
The company recently completed a composite copper foil plant in Ansan and is preparing operations, with permits expected this month. It has also secured orders for glass via (TGV) cleaning and etching equipment, and is developing vertical tools for glass core substrates.
Why now? Order momentum is the backdrop. Taesung said cumulative orders this year exceeded US$234.8M — about 7.4 times its 2025 annual revenue of US$31.8M — driven by chipmakers ramping investment for AI servers. Much of that volume is due for delivery next year, requiring upfront cash for materials and manufacturing.
The bond carries a 0% coupon and no repricing clause, limiting financing costs and one source of potential dilution. "We can expand new business investment while minimising financial cost burden," chief executive officer Kim Jong-hak said.
What could go wrong? The glass substrate market remains in pilot and customer-qualification stages, with Korean peers Samsung Electro-MechanicsDealroom has a profile for this one. Try Dealroom →, SKCDealroom has a profile for this one. Try Dealroom →'s AbsolicsDealroom has a profile for this one. Try Dealroom →, and LG InnotekDealroom has a profile for this one. Try Dealroom → targeting commercialisation around 2027–28. Taesung's raise funds a bet on a growing sector, not a proven demand stream, and it must still demonstrate stable yields and win customers. Conversion of the bond could also dilute existing shareholders, even without repricing.
The signal: At a scale that ranks among the larger rounds in its cohort, the raise — following last year's roughly US$75.9M rights offering — marks Taesung's accelerating pivot from equipment vendor toward materials and advanced packaging, betting that AI-driven demand will carry it into unproven markets.
