As part of the transaction, GSAM has entered into a long-term strategic partnership agreement with NN Group to manage a portfolio of assets worth approximately $180bn, making it one of the largest non-affiliated insurance asset managers globally, with over $550bn in assets under supervision.

The group said the acquisition also provides a "foundation for further growth" in its European fiduciary management business, building on its existing US and UK platforms.

David Solomon, chairman and CEO of Goldman Sachs, said: "This acquisition advances our commitment to put sustainability at the heart of our investment platform. It adds scale to our European client franchise and extends our leadership in insurance asset management.

The acquisition is Solomon's largest since he became chief executive in 2018.
