Tosoh completes September share buyback, exceeds previous goal

Tosoh Corporation announced its acquisition of 1,232,000 common shares during September 2025, with a total acquisition cost of 2,891,846,000 yen. These shares were purchased through market transactions based on a discretionary trading contract, concluding a period from September 1 to September 30, 2025.

This action is part of a larger share buyback program approved by the board of directors on August 5, 2025, which authorized the acquisition of up to 17,000,000 common shares (5.34% of total issued shares excluding treasury shares) or a maximum of 25 bn yen, from August 6, 2025, to March 31, 2026.

As of September 30, 2025, the aggregate number of shares acquired under this resolution has reached 2,794,000 common shares, totaling 6,496,123,850 yen. This demonstrates Tosoh's ongoing commitment to its share repurchase program, aimed at optimizing its capital structure and enhancing shareholder returns. The company’s continued efforts in acquiring its own shares align with its long-term financial strategies.
