The Mitsubishi Plastics share exchange: performance products moved under the parent (2007)

A rearrangement that stopped it being a subsidiary's subsidiary

Mitsubishi Plastics was part of a performance-products business that earned 49% of consolidated operating profit in FY2005, and yet it remained merely a subsidiary of Mitsubishi Chemical, the company carrying petrochemicals. The fact that the operating results of petrochemicals and performance products offset each other in only three of seven reporting periods shows how thin the grounds were for holding both under the same company. The meaning of the share exchange lay less in the delisting than in lifting performance products out from under petrochemicals and moving them to a position where the holding company could decide on their investment directly.

That said, performance products did not become independent once lifted. The new Mitsubishi Plastics, formed in April 2008 by merging in four companies, disappeared as a legal entity nine years later in the 2017 merger with Mitsubishi Chemical and Mitsubishi Rayon, and performance products returned to being a division inside a single company. Split the businesses apart and let them run themselves, or gather them into one company and make them cooperate? Mitsubishi Chemical Group tried both within a decade, and the 2007 share exchange stands at one end of that pendulum.
