A plan for Mitsui Chemicals to acquire JSR for approximately ¥1.84 trillion has been reported, focusing attention on the scale of the acquisition and industry consolidation. The period from 9 to 16 November 2026 has been cited as the implementation period.
Mitsui Chemicals' acquisition of JSR is reported to be driving further consolidation among major chemical companies. The acquisition price is said to be ¥1.84 trillion, and corporate integration is expected to advance further.
JSR is the target company. The transaction involves the acquisition of ownership through an acquisition, rather than being withdrawn as part of a capital alliance.
A large acquisition of this type could involve reorganizing raw-material supply and research and development systems, as well as integrating product portfolios, and is expected to affect the competitive environment in related markets.
The announced implementation period is from 9 November 2026 to 16 November 2026. Developments may change depending on future procedures and the results of regulatory reviews.
