Toshiba to gradually sell Kioxia stake after ex-chip unit's IPO

Toshiba Corp plans to gradually unwind its 40% stake in Kioxia Holdings after the world's second-largest flash memory chip firm lists its shares in an IPO later this year, two people familiar with the matter said on Saturday.

The Japanese industrial conglomerate is considering distributing about half or more of after-tax proceeds from the sale back to shareholders, the sources told Reuters, asking not to be identified because the matter is private.

Toshiba said in a filing with the Tokyo stock exchange on Saturday that it was considering various possibilities for shareholder returns, such as the handling of assets and reviewing its portfolio.

The company said nothing has been decided over its stake in Kioxia, the former flash memory chips unit it sold to a consortium led by U.S. private equity firm Bain Capital for $18 billion in 2018.

Toshiba bought its Kioxia stake as part of that deal.

The initial public offering of Kioxia could be Japan's biggest listing this year, sources have said.

Many overseas fund investors are urging Toshiba to sell the stake on the grounds that flash memory chips, used in smartphones and data storage servers, are a highly volatile business that could sway Toshiba's earnings, the source said.

Toshiba has been facing pressure from activist funds agitating for changes since the company sold 600 billion yen ($5.6 billion) of stock to dozens of foreign hedge funds during a crisis stemming from the bankruptcy of the U.S. nuclear power unit in 2017. Nearly 70% of its shareholders are non-Japanese.
