Alleghany

Alleghany Corporation is a major investment holding company that was acquired by Berkshire Hathaway in October 2022 for approximately $11.6 billion. While primarily recognized for its property and casualty insurance operations, the company held significant influence in the life sciences sector through its subsidiary IPS-Integrated Project Services (IPS). IPS is a global leader in providing technical consulting, architecture, engineering, and construction management for complex pharmaceutical and biotechnology manufacturing facilities. Shortly before Alleghany's acquisition by Berkshire Hathaway, its capital division divested its interest in IPS to the private equity firm Berkshire Partners. Today, Alleghany operates as a diversified subsidiary of Berkshire Hathaway, managing a wide range of industrial and service-oriented businesses.
