Advantest's monthly self-share purchase report, filed with the Kanto Local Finance Bureau on September 15, 2026, shows the chipmaker has effectively used up the cash ceiling on its buyback program while still holding well below the share-volume limit the board approved.
The board authorized the program on October 28, 2025, permitting purchases of up to 18,000,000 shares for up to ¥150bn between November 4, 2025 and October 28, 2026. During August 2026 alone, Advantest bought 459,700 shares for ¥15.62bn across 14 trading days, including a single-day purchase of 93,000 shares for ¥3.36bn on August 20.
That brought cumulative repurchases through August 31 to 5,759,000 shares for ¥149,996,716,000, close enough to the ¥150bn ceiling that the filing itself records the value progress as 100.00%. The share-count progress, by contrast, stands at just 31.99% of the 18 million-share cap.
| Measure | Cumulative (through Aug 31, 2026) | Board Authorization | Progress |
|---|---|---|---|
| Shares repurchased | 5,759,000 shares | 18,000,000 shares | 31.99% |
| Value repurchased | ¥149,996,716,000 (~¥150.0bn) | ¥150,000,000,000 (~¥150bn) | 100.00% |
The gap between the two figures means Advantest reached its yen-denominated spending limit long before exhausting the share-count allowance, with roughly two months still remaining in the authorized buying window that runs to October 28, 2026.
The same filing shows Advantest disposed of 131,161 treasury shares worth ¥1,932,919,657 on August 28 as restricted stock compensation, drawing down part of what it had bought back. As of August 31, 2026, the company held 10,047,051 treasury shares against 732,000,000 shares outstanding.
