Boyd Watterson Asset Management and Amber Infrastructure Group have completed their previously announced business combination to establish a global alternatives investment platform.

The financial terms of the deal were not revealed.

Announced in May this year, the transaction was completed following the approval of all necessary investor consents and regulatory approvals, including the consent of the UK’s Financial Conduct Authority (FCA).

Headquartered in London, Amber Infrastructure oversees £14bn in assets under management (AUM). The firm is engaged in mobilising private capital to deliver essential infrastructure projects globally across sectors.

Amber Infrastructure CEO Gavin Tait said: “The ability to operate under a unified parent company brings increased long-term investment potential to our clients.

“Our firms share a strong commitment to delivering exceptional client service and have extensive experience collaborating with governments and governmental agencies.

“This strategic alignment will provide Amber with greater scale to expand its global infrastructure business, including opportunities in US infrastructure, while also unlocking new possibilities for Boyd Watterson’s clients.”

The merger has created a global asset management platform with around $35.7bn in AUM, specialising in real estate, infrastructure, and fixed income investments.

The enlarged company, which includes operating subsidiaries, is supported by more than 300 investment professionals and offices in eight US cities and across 12 countries.

Clients, partners, and employees of both Boyd Watterson and Amber Infrastructure are expected to benefit from the increased scale of the combined platform.

It will offer them a broader range of products, a diversified revenue base, and greater investment expertise.

Operating under the parent company Boyd Watterson, the merger expands both firms’ capabilities and reach, providing new investment opportunities for their global clientele.

Established in 1928, Boyd Watterson has $18.2bn in total AUM across its real estate and fixed income investment portfolios.

Boyd Watterson CEO Brian Gevry said: “We are excited to have officially joined forces, which opens up exciting new investment opportunities for our clients.

“We’re both leaders in our respective asset classes, with a shared commitment to excellence and innovation. Now we are able to combine our strengths to offer enhanced products to our clients that surpass their expectations and drive long-term success.”
