A consortium led by investment fund Japan Industrial Partners Inc. will start a tender offer to buy all outstanding Toshiba shares at ¥4,620 per share between Aug. 8 and Sep. 20, Toshiba said in a statement on Monday. That price, above Toshiba’s closing share price of ¥4,584, was unchanged from a March announcement.

Toshiba, which holds knowhow spanning air conditioners and nuclear power equipment to semiconductors and quantum computing, sees the take-private bid as a chance to regain its footing following more than a decade of scandals and management overhauls.

The inventor of NAND flash memory was forced to sell its majority stake in its memory chip business to a group led by Bain Capital in 2018. Now re-branded Kioxia Holdings Corp., that unit has fallen technologically behind Samsung Electronics Co. and SK Hynix Inc. It’s in talks to merge with Western Digital Corp. as sliding prices eat into its ability to invest and keep up.
