Deal News | Jun 27, 2025 | Brown Advisory Inc

Brown Advisory, a noted investment firm, is in advanced discussions with London-based Marylebone Partners LLP to join forces and build a superior endowment-style offering outside the U.S. By aligning with Marylebone, Brown Advisory aims to enhance its investment capabilities, offering a broader range of investment opportunities. Marylebone, known for its prowess in identifying distinct investment opportunities, will bring three decades of experience and a significant database in investment and risk analytics. The partnership is poised to enhance Brown Advisory's global resources, offer access to independently managed funds, and provide co-investment opportunities and direct investments. This strategic alliance furthers Brown Advisory's commitment to client service through its distinct investment platform for endowments, families, and trusts. The transaction is pending regulatory approval, and Marylebone will continue to manage its client portfolios, including Majedie Investments PLC, within the Brown Advisory framework.
