Punter Southall Group (PSG) has bought a minority stake in Kent-based wealth firm Argentis Financial Group (AFG).
Through the strategic partnership, which remains subject to regulatory approval, the UK consulting group will help AFG grow its financial planning and wealth management business.
PSG group managing director Kenneth McKelvey will join the board of AFG, which will continue to operate independently under the leadership of chief executive David Taplin.
AFG was established in November 2005 in Canterbury. In 2008 the business opened offices in Cobham, Surrey and Salisbury, Wiltshire it set up shop in central London a year later.
By the end of 2013, AFG which employs 65 people, was responsible for more than £1.3 billion.
McKelvey said in a statement: 'We look forward to working in partnership with the team at Argentis to help their business expand. We’ve known them for some time and are confident that our strong relationship will lead to greater commercial opportunities.'
Taplin added: 'Punter Southall Group’s investment and support will enable us to move the business forward while continuing to provide an excellent service to our clients.'
The news comes a month after PSG announced the merger of its institutional investment advisory arm, P-Solve, with River and Mercantile Asset Management.
