Deal News | Mar 28, 2025 | Re-Insurance News

Mitsui Sumitomo Insurance Co., Ltd. (MSI), a leading Japanese property and casualty insurance firm, has agreed to acquire 15% of W. R. Berkley Corporation's outstanding common stock. W. R. Berkley is a commercial lines P&C insurance company. The acquisition will not involve direct purchases from W. R. Berkley or the Berkley Family, but rather from third-party investors through open market or private transactions. MSI has also secured a voting arrangement with a Berkley Family-owned entity, which currently holds about 16% of W. R. Berkley's shares. This agreement will allow MSI to vote according to the Berkley Family's recommendations once they hold at least 4.9% of the stock, barring specific circumstances. Once MSI's stake reaches 12.5%, the Berkley Family will support an MSI director's nomination to the Board. The investment awaits regulatory approval and is expected to be completed by March 2026.
