Rathbone Brothers has signed a deal to acquire the remaining 80.1% stake in Vision Independent Financial Planning and Castle Investment Solutions (Vision Group).
In October 2012, Rathbones acquired a 19.9% stake in the Vision Group for £2m.
Vision, which is an independent specialist financial advice network focusing on HNW private clients, had £925m of assets under advice and 78 advisers at the end of August 2015.
Castle operates as a sister company to Vision, providing it with administrative services.
Commenting on the deal, Rathbones CEO Philip Howell said: "Our decision to acquire the Vision Group is a reflection of its proven ability to grow and the strong relationship we have built up in the last five years. We very much look forward to sharing in its continued success."
Mike Webb, Executive in charge of distribution at Rathbones said: "Vision’s independent status will remain intact, securing an unequivocal focus on clients’ interests and suitability."
