Idemitsu Kosan Launches ¥25 Billion Share Buyback and Cancellation Program

An update from Idemitsu Kosan Co ( (JP:5019) ) is now available.

Idemitsu Kosan’s board has approved a new share buyback and subsequent cancellation as part of its medium-term shareholder return policy, which targets a total payout ratio of at least 50% based on three-year cumulative net income excluding inventory effects. The company plans to acquire up to ¥25 billion of its common shares, representing up to 25 million shares or about 2.0% of its outstanding stock, through market purchases between November 12, 2026 and March 11, 2027, with all repurchased shares scheduled for retirement on March 31, 2027.

This program follows an earlier ¥30 billion buyback authorization from November 2025, of which ¥13.2 billion had been executed by the end of April 2026, and it underscores Idemitsu’s continued focus on capital efficiency and direct returns to shareholders. By reducing the number of shares outstanding through cancellations, the initiative is expected to enhance per-share metrics and could support the company’s valuation, while signaling confidence in its earnings trajectory during the current medium-term management plan period.

The most recent analyst rating on (JP:5019) stock is a Hold with a Yen1060.00 price target. To see the full list of analyst forecasts on Idemitsu Kosan Co stock, see the JP:5019 Stock Forecast page.
