Carving out Toshiba Memory: the Bain consortium, and the birth of Kioxia (2017)

A company born by leaving the hands that invented it

At the centre of this birth is a paradox: a business that was earning healthily was cut out of its parent for reasons that had nothing to do with its own performance. The NAND flash memory Toshiba was first in the world to create had, right up to the moment of separation, been producing most of the parent’s profit. It was sold not because it had failed, but because a parent overwhelmed by the failure of its nuclear business had no other way of turning an asset into cash at that price. A sale forced by crisis is what delivered an independent company into the world.

The same transaction looks different depending on where you stand — with Toshiba as seller, with the Bain consortium as buyer, or with the Kioxia that was bought into existence. For Toshiba it was the pain of giving up the family treasure; for Bain, an investment made in expectation of future appreciation; for Kioxia, the starting point of standing alone with the Toshiba name removed. Whether a business that became a separate company more than thirty years after the invention would grow — from a foreign fund’s capital as its point of entry — into a company that raises money from the market on its own account depended on the memory cycle and on what it made of that independence. Look at one deal from both sides at once, seller and buyer, and the history of Japanese semiconductors rises up as a single continuous story.
