Shin-Etsu Chemical’s Share Buyback Completed | June 17, 2026

Overview of Capital Policy

Shin-Etsu Chemical conducted a share buyback from May 21 to June 17, 2026, purchasing a total of approximately 13.2 billion yen (10,149,881 shares at 5,235 yen per share). The buyback was conducted by the pro-rata method, with some purchases due to oversubscription. As a result, approximately 22.5% of the maximum allowable 45,000,000 treasury shares were acquired.

Results of the Buyback and Future Outlook

Since the number of shares applied for exceeded the scheduled purchase amount during the buyback period, the excess shares were not purchased, and the total buyback amount was close to the applied number. This buyback aims to improve capital efficiency and strengthen shareholder returns, which may influence future shareholder return policies and capital strategy.
