Kioxia Holdings told the Kanto Local Finance Bureau it has effectively used up the ¥800bn cash authorization behind its share buyback, well before completing the share-count side of the program. Under a board resolution dated July 31, 2026, the company set out to repurchase up to 30 million common shares for up to ¥800bn through open-market purchases on the Tokyo Stock Exchange, running from August 3 to October 30, 2026.
The monthly status report, filed September 11, shows the entire spending happened in a six-day burst. Between August 3 and August 10, Kioxia bought 16,133,500 shares for ¥800.0bn, a figure the filing itself records as 100.00% of the value authorization. The single biggest day was August 3, when the company bought 4,281,300 shares for ¥212.3bn.
| Metric | Board authorization | Acquired by Aug. 31 | Progress |
|---|---|---|---|
| Shares | 30,000,000 | 16,133,500 | 53.78% |
| Value | ¥800bn | ¥800.0bn | 100.00% |
That leaves the buyback in an unusual position: fully funded on paper, but only just over halfway to its share-count goal, with more than seven weeks left on the clock before the October 30 deadline. The filing does not say whether the board intends to top up the value cap or let the program run out short of the 30 million-share target.
At period end, Kioxia had 548,639,034 shares outstanding and held 16,134,027 shares in treasury. No repurchased shares were disposed of during the reporting month.
