Corient, a Miami-based wealth management firm serving high-net-worth and ultra-high-net-worth clients, announced on 1 June 2026 that it had completed its acquisitions of Stonehage Fleming and Stanhope Capital Group, lifting global client assets to approximately $508bn and accelerating its international expansion.
The deal gives Corient a foothold in Luxembourg through Stonehage Fleming’s local presence. Stonehage Fleming’s Luxembourg page states that the firm is now Corient and that its website will become inactive from 1 July 2026, while Corient also lists Luxembourg among its regional markets.
Corient stated that, following the acquisitions, it has become the world’s largest non-bank wealth manager and multi-family office focused on ultra-high-net-worth and high-net-worth clients.
Scale push
The acquisitions bring together three wealth management and family office businesses serving wealthy individuals, families and businesses across several regions. Corient, established in 2020, now has more than 300 partners and more than 2,200 employees.
The group said the acquisitions, alongside recent regulatory approval for its expansion into Canada, mean it now serves clients from offices in the US, Canada, Europe, Africa and Asia. Corient added that services are provided only in jurisdictions where authorised and may not be available in all locations or for all client types.
Luxembourg presence
Stonehage Fleming has served wealthy families and entrepreneurs through family office and wealth planning services. Its Luxembourg page highlights services including governance and succession planning, administration of international structures such as trusts and companies, investment portfolio management, risk mitigation, private capital opportunities, reporting across client wealth, banking and treasury coordination, corporate finance advice and the management of art collections and other lifestyle assets.
That makes the transaction relevant to Luxembourg’s private wealth and family office market, where cross-border planning, succession, investment structuring and advisory services remain core activities.
Corient has not separately disclosed Luxembourg-specific assets, headcount or transaction details.
Partnership model
Corient said the enlarged business will operate under a private partnership model similar to those used by professional services firms. Kurt MacAlpine, founding partner and chief executive officer of Corient, stated that the firm was “thrilled to welcome” new partners at Stonehage Fleming and Stanhope Capital Group as it builds a global business based on partnership, collaboration and client service.
He added that Corient’s model gives clients access to the wider expertise and resources of the firm rather than depending on a single adviser. The company said the structure supports integrated wealth management and family office capabilities at global scale.
The financial terms of the acquisitions were not disclosed.
