On November 4, Chosun Biz reported that ISU Group is actively pursuing the acquisition of JEIO, a KOSDAQ-listed developer of carbon materials, as part of ISU Petasys's broader strategy to diversify its PCB-focused business.

Earlier rumors suggested ISU Petasys was preparing a large-scale capital increase to acquire a secondary battery material company. It is now confirmed that JEIO is the acquisition target, with ISU Group seeking to purchase around 40% of JEIO’s shares—held by parties close to JEIO’s CEO Kang Deuk-joo—for approximately 300 billion KRW (about 215 million USD or 1.5 billion CNY).

Following these reports, ISU Petasys issued a disclosure on November 4 stating that it is indeed exploring multiple options, including mergers and acquisitions, to expand its business structure. "We are reviewing various measures, including M&A, to diversify our business focus beyond PCBs, though no specific decisions have been finalized," a company representative noted. The company also mentioned it is considering a paid-in capital increase to fund business expansion and investment in PCB advancements but emphasized that plans remain preliminary.

JEIO also acknowledged on November 4 that it is exploring various options to expand its carbon nanotube (CNT) business, though no specific measures have been confirmed.

The potential acquisition of JEIO is noteworthy given the rising importance of carbon nanotubes and secondary battery materials in high-tech fields like electric vehicles and advanced electronics. By acquiring JEIO, ISU Petasys aims to secure a foothold in these emerging markets, aligning with its goal of reducing reliance on the PCB sector through strategic acquisitions and expanded technological capabilities.
