Kioxia Holdings, Japan’s major memory chipmaker, was listed on the Tokyo Stock Exchange's Prime Market on December 18.  

The stock opened at 1,440 yen, below the offer price of 1,455 yen, but closed at 1,601 yen, above the IPO price.  

The market capitalization calculated at the closing price is approximately 863 billion yen.  

Kioxia was founded by separating Toshiba's semiconductor memory business and changed its name from the original “Toshiba Memory” in 2019.  

It had planned to go public in 2020.  

However, it was cancelled due to export restrictions caused by trade friction between the U.S. and China.  

The listing scheduled for October of this year was also postponed due to the deterioration of the semiconductor market.
