Berkshire's backing and a new buyback lift Marubeni

  • Berkshire raises Marubeni stake above 10% Berkshire Hathaway increased its stake in Marubeni above 10%, alongside Mitsubishi and Sumitomo. This is a strong vote of confidence from a famous long-term investor, drawing attention to Marubeni's low valuation and shareholder-friendly returns, which can pull in other buyers and support the share price.

    A major new endorsement from Berkshire directly boosts demand for Marubeni shares.

  • Marubeni announces ¥100bn share buyback Marubeni will buy back up to 2.5% of its shares for up to ¥100 billion through March 2027. Buybacks reduce the number of shares, lifting earnings per share, and signal confidence in cash flow. This directly supports the stock price by returning cash to shareholders.

    A concrete new capital return action that mechanically supports the share price.

  • Berkshire says rising Japan bond yields are not a problem Berkshire CEO Greg Abel said Japan's higher bond yields are not a fundamental challenge for trading houses, and Berkshire may keep borrowing in yen. This eases fears that higher rates would hurt Marubeni's funding costs or Berkshire's willingness to hold, reinforcing the long-term investment case.

    Directly addresses a key risk (rising rates) and reaffirms long-term support.

  • Offshore wind project faces partner exit risk BP may withdraw from the Yamagata offshore wind consortium that includes Marubeni, due to soaring construction costs. If more partners quit, Marubeni could face higher costs or delays. This is a real counterweight, though government support may soften the blow.

    A genuine risk that could weigh on Marubeni's renewable energy prospects.
