In addition, five MFS taxable fixed income funds will combine to form a multi-sector fixed income closed-end fund, including private credit, with around $1.4bn in AUM. 

Aberdeen’s fixed income global head, Jonathan Mondillo, will manage both funds. 

Employees or corporate entities will not be transferred as part of the acquisition. 

Aberdeen Group CEO Jason Windsor said: “We are delighted to add further scale to our US closed-end fund platform, with this highly synergistic acquisition. 

“As we implement our strategy to become the UK’s leading Wealth and Investment group we will continue to invest in areas of strength where we see significant room for growth.” 

Aberdeen Investments is a global asset manager, focusing on public and private markets, including specialist equities, credit and real assets. 

The firm managed about £382bn on behalf of clients, as of 30 September 2025. 

Aberdeen Investments corporate finance managing director and closed-end funds head Christian Pittard said:  “The enlarged funds will come with real scale and will focus on areas of deep expertise for Aberdeen where we see clear potential for further growth. 

“MFS pioneered US mutual funds back in 1924, and we are proud they have chosen Aberdeen for this agreement.” 

In August this year, Aberdeen Group agreed to divest its financial planning unit, Aberdeen Financial Planning, to Ascot Lloyd.
