Exclusive-Japan fund JIC plans to sell JSR to Mitsui Chemicals, sources say
Japan Investment Corp (JIC) plans to sell chipmaker JSR to Mitsui Chemicals for potentially over 1.3 trillion yen ($8.2 billion). The deal, expected soon, follows JIC's 2021 acquisition of JSR for 900 billion yen. Mitsui Chemicals' shares fell 7% after the news. JSR produces photoresists for semiconductors, and Mitsui is expanding in chip materials. JIC aims to leverage AI-driven valuation increases in the sector.
