Mitsui Chemicals, Inc.
Mitsui Chemicals, Inc. (Headquarters: Chuo-ku, Tokyo; President and CEO: Osamu Hashimoto; hereinafter "Mitsui Chemicals") and Ketjen Netherlands Holdings B.V. (Headquartered in Amsterdam, Kingdom of the Netherlands; President and CEO: Michael J. Simmons; hereinafter "Ketjen") have entered into a share purchase agreement for Nippon Aluminum Alkyls Ltd. (Headquarters: Chiyoda-ku, Tokyo; President and CEO: Kenji Hiraiwa; hereinafter "NAA"), a company engaged in the manufacturing and sales of organometallic compounds such as alkyl aluminum. As of today, Mitsui Chemicals has acquired all shares of NAA, which are held by Ketjen, making it a wholly owned subsidiary.
Since its establishment in 1968, NAA has been manufacturing and selling a wide range of high-quality alkyl aluminum products. Their applications span a wide range of uses that support industry and society, including catalysts for polyolefins, reducing agents for pharmaceutical synthesis, raw materials for asymmetric synthesis catalysts, and raw materials for electronic information materials.
Ketjen is a provider of advanced catalysts solutions to leading producers in the petrochemical, refining, and specialty chemical industries. “We are excited that NAA will be acquired by a company like Mitsui that is dedicated to fostering the growth of this business,” said Ketjen President Michael J. Simmons.
Mitsui Chemicals’ VISION 2030 Long-Term Business Plan positions “Chemistry for Sustainable World” as the company’s ideal vision. In pursuing portfolio reform as a basic strategy for achieving this plan, Mitsui Chemicals aims to become a truly global specialty company by leaning on the two key pillars of a high-growth, high-profitability global specialty chemicals business and a sustainable green chemicals business centered on competitive derivatives. We have decided to make it a wholly owned subsidiary of Mitsui Chemicals in order to efficiently and proactively allocate our management resources toward the production and sales of catalysts and co-catalysts used in the manufacture of chemical products such as polyolefins, synthetic rubber, and high-grade alcohols, as well as organometallics like alkyl aluminum and their derivatives used in pharmaceuticals and electronic materials. This aims not only to contribute to the raw materials for electronic materials within the ICT solutions business but also to ensure the stable supply of co-catalysts used in polyolefin production.
