The London-based financial advisory group, which was founded by Sean Scahill and Peter Kelsey in 2010, will see all 28 employees join Close Brothers. The deal remains subject to FCA approval.
Eos currently advises on over £300m ($432m, €381m) of client assets. The firm specialises in servicing high net worth clients, particularly in the media and sports industries.
Chief executive of Close Brothers AM Martin Andrew said: “We are committed to building a market-leading integrated wealth management business and are keen to augment our strong organic growth with selective, high-quality acquisitions.
“The acquisition of Eos Wealth Management fits perfectly with our strategy. It will be a pleasure to welcome new colleagues who share our ambition and will help us realise it.”
“It was really important for us to find a buyer who had our clients’ best interests at heart. Close Brothers Asset Management fits the bill perfectly,” added Kelsey.
“The company’s professional approach closely aligns with our own, and our clients will benefit from Close Brothers’ rigorous and successful approach to investment management,” he said.
