Idemitsu Kosan announces share buyback, upgraded forecast

Idemitsu Kosan announced a resolution to acquire up to 43 million common shares, representing 3.5% of total shares outstanding, for a maximum of 30 billion yen. All acquired shares will be canceled by March 31, 2027. This share buyback, occurring between November 12, 2025, and November 11, 2026, is part of the company's shareholder returns policy, aiming for a payout ratio of 50% or more based on cumulative net income over three years.

In a related update, Idemitsu Kosan revised its consolidated earnings forecast for the fiscal year ending March 31, 2026. Net sales are now projected at 7,950,000 million yen, up from 7,900,000 million yen. Operating income is expected to increase significantly to 68,000 million yen from 37,000 million yen, largely due to robust domestic margins in the petroleum segment. Net income attributable to owners of the parent is consequently revised upward to 75,000 million yen from 50,000 million yen.

The company also announced the acquisition of Fuji Oil Company, Ltd. as a consolidated subsidiary through a tender offer completed on October 28, 2025, bringing Idemitsu's voting equity interest to 75.03%. The financial impact of this acquisition is currently being assessed.
