Mitsui Chemicals Inc. announced on November 9 that it will acquire JSR Corp., a major semiconductor material manufacturer, for approximately 1.84 trillion yen. The acquisition will involve purchasing JSR shares from Japan Investment Corp., which is backed by the government. Additionally, the Development Bank of Japan will participate in the deal, acquiring JSR shares valued at 200 billion yen. The total cost of the share acquisition will reach around 1.39 trillion yen, and Mitsui Chemicals will also assume JSR's interest-bearing debt of about 440 billion yen. 

JSR, based in Tokyo, is not publicly traded and holds one of the largest market shares globally for photoresist, a crucial resin material for semiconductor circuits. The deal is expected to close in the second half of fiscal 2027, with JSR shares acquired by JIC being converted into preferred shares without voting rights. Mitsui Chemicals aims to enhance its semiconductor-related business, targeting a profit increase of 40 billion yen by fiscal 2035 through sales growth and cost optimization from the acquisition of JSR.
