Signed acquisition agreement sets out purchase and financing
Mitsui Chemicals announced on November 9 that it had signed an agreement to acquire chipmaking-materials supplier JSR, with investment from the Development Bank of Japan. Reuters reported a transaction value of ¥1.84 trillion. DBJ will invest ¥200 billion, while Mitsui plans to sell shares worth up to ¥150 billion to help finance the purchase. Those financing amounts describe contributions toward funding the transaction; they are not alternative valuations of JSR. The signed agreement marks a new step beyond preliminary reporting of the proposed acquisition.
