Idemitsu Kosan Co ( (JP:5019) ) just unveiled an update.
Idemitsu Kosan has disclosed the latest status of its ongoing share buyback program authorized under Japan’s Companies Act, reporting that it repurchased 1,571,700 common shares on the market between March 1 and March 31, 2026, for a total of about 2.31 billion yen. This tranche forms part of a broader board-approved plan, launched in November 2025, to buy back up to 43 million shares or 30 billion yen by November 2026, signaling continued capital return to shareholders and active balance sheet management.
