Bridgestone's ¥150bn buyback ran out of money before it ran out of shares. Its monthly buyback status report for September shows cumulative purchases of 42,649,100 shares at a total cost just under ¥150bn, which the report records as 100.0% of the value ceiling and 71.1% of the 60,000,000-share ceiling.
What the board authorised
The board resolved on February 16, 2026 to buy back up to 60,000,000 shares and up to ¥150bn, with an acquisition period of February 17 to August 31, 2026. The method was market purchases under a discretionary trading contract. The 60,000,000 shares were a ceiling, and the programme ended with 71.1% of it used.
September deliveries and the cancellation
The report lists two September purchases: 173,900 shares for ¥717.7mn on September 1 and 173,800 shares for ¥720.8mn on September 2, together 347,700 shares for ¥1.44bn. A footnote explains why purchases appear after the August 31 end date: the acquisition period is counted by trade date, while the September rows are counted by delivery date.
On September 18, Bridgestone cancelled 42,649,100 treasury shares, the same number as its cumulative purchases, at a book value of ¥134.34bn. That is below the ¥150bn purchase cost, and the report does not explain the difference. Earlier Tokyo Brief coverage
