US headquartered Tiedemann Group has completed its acquisition of UK's Alvarium Investments, after a long journey from announcing the prospective deal back in 2021. 

The international ramifications of this mega-merger include seeing Switzerland's Tiedemann Constantia rolled into the combined Alvarium Tiedemann group, which this week commenced trading on NASDAQ.

The M&A deal involves combined assets of $60bn focused on high-net-worth investors, the most lucrative of clients for financial advisers to work with. In November, the combined companies reported $8.2m in net income for the third quarter of last year.

The aim is to manage more than $100bn in client assets by 2026. 

Michael Tiedemann, chief executive of Alvarium Tiedemann, said: "We've established a truly distinctive, global wealth and asset management firm with a breadth of international capabilities and access to an entrepreneurial network. Today marks our next chapter. 

"In 2023, we plan to capitalise on the opportunity to provide our clients and partners with best-in-class financial advisory services, access to alternative investment opportunities and a leading impact investing offering."
