Fisher Investments has finalized a strategic partnership with Advent International and the Abu Dhabi Investment Authority (ADIA) through a $3 billion minority common stock investment. This investment values Fisher Investments at $12.75 billion and is part of founder Ken Fisher's long-term estate planning strategy. Despite this new investment, Ken Fisher retains a majority controlling interest, holding over 70% of the voting shares.

The partnership marks the first outside investment for Fisher Investments, which has previously been owned solely by family and employees. Ken Fisher remains actively involved as Executive Chairman and Co-Chief Investment Officer, while CEO Damian Ornani oversees daily operations. The investment includes no options or non-common stock preferences, ensuring proportional voting rights for Advent and ADIA based on their ownership.

Ken Fisher emphasized that the transaction is designed to secure the firm's independence and culture, while also addressing potential future estate tax considerations. He expressed confidence in Advent and ADIA as partners who appreciate Fisher Investments' operational and cultural values. Damian Ornani welcomed their support in expanding the firm's global client base.

David Mussafer, Managing Partner at Advent, expressed excitement about the partnership, highlighting the growing demand for Fisher Investments' personalized financial expertise. The collaboration aims to leverage Advent's experience in the financial services sector to foster Fisher Investments' growth.

As of the end of 2024, Fisher Investments managed nearly $300 billion for over 170,000 clients worldwide, including a significant number of U.S. private clients and major institutional clients. The firm operates as an independent, fee-only investment adviser, with a history dating back to 1979.

Advent International, founded in 1984, is a prominent global private equity investor with over $88.8 billion in assets under management. The firm focuses on transforming businesses through partnerships with management teams and has developed expertise across various sectors, including financial services, consumer goods, healthcare, and technology.

The Abu Dhabi Investment Authority, established in 1976, is a diversified investment institution that invests on behalf of the Government of Abu Dhabi, focusing on long-term value creation.

This partnership is expected to enhance Fisher Investments' capabilities and support its mission of delivering exceptional client service while maintaining its unique culture and independence.
