Berkshire Hathaway becomes major shareholder in Mitsui

Mitsui & Co. announced on September 22, 2025, a change in its major shareholders. US-based Berkshire Hathaway Inc. informed Mitsui on September 21, 2025, that it had acquired additional shares, resulting in its holding of 10% or more of Mitsui’s voting rights, thereby becoming a major shareholder. Prior to this, Mitsui confirmed that Berkshire Hathaway’s acquisitions were made through its wholly-owned subsidiary, National Indemnity Company.

Mitsui is awaiting further disclosures, such as amendments to large shareholding reports, to confirm the exact ratio of voting rights held by National Indemnity Company before and after the change. National Indemnity Company, located in Omaha, Nebraska, United States, is in the insurance business, with Donald F. Wurster serving as president.

Mitsui noted that the change is based on information from Berkshire Hathaway Inc., which had previously indicated plans to hold Mitsui's shares for a long period and consider future acquisitions.
