Two years after $11M robowon deal, Korea Zinc leaves US$8.38M unpaid
What's the deal? Korea ZincDealroom has a profile for this one. Try Dealroom →'s 2024 acquisition of robotics maker robowonDealroom has a profile for this one. Try Dealroom → is showing strain, with the target's equity deficit deepening two years on. Of the US$12.6M committed for new shares, Korea Zinc has paid only US$4.19M in cash, leaving US$8.38M outstanding.
The backstory: Korea Zinc announced the acquisition in September 2024 and took a 33.33% stake in October, folding robowon in as a consolidated subsidiary. Robowon makes delta robots and AI-based waste-sorting robots.
Korea Zinc said it bought the company to automate its e-waste sorting line. The deal fit the resource-recycling leg of chairman Choi Yun-beom's 2022 "Troika Drive" strategy, alongside renewable energy and batteries.
By the numbers: Robowon's finances have worsened since the deal. In 2025 it posted revenue of US$1.86M and a net loss of US$2.62M, dragging total equity to minus US$2.62M; a further US$897.1K loss in the first half of this year pushed equity to minus US$3.52M.
Total assets fell from US$6.09M at the end of 2024 to US$2.59M by June this year. The US$8.38M Korea Zinc has yet to pay exceeds the size of robowon's deficit, meaning payment could flip equity positive — yet no such move came in two years.
What could go wrong? Robowon's equity shortfall has grown, but Korea Zinc had not impaired the goodwill it booked at acquisition through the end of last year. It valued identifiable net assets at US$12.4M and recognised US$4.83M in goodwill, which stayed unchanged after an impairment test.
Korea Zinc said it ran the assessment with an accounting firm and found "fair value sufficiently exceeds book value" (translated from Korean), so no impairment was recognised. A company representative said the contract terms with robowon carry no disclosure obligation and could not be confirmed officially.
The signal: The case shows the gap between acquisition promises and follow-through. Korea Zinc argues a robotics firm's worth rests on technology and future cash flows rather than current book value — a bet that has yet to pay off two years in.
