Howden, a global insurance broking group, has agreed to acquire Atlantic Global Risk LLC, an independent transaction liability insurance broker focused on complex M&A and private equity risks in North America.
The acquisition is designed to accelerate Howden’s expansion in the US retail broking market and to establish a global leader in transaction liability insurance.
While the financial terms of the deal were not disclosed, the transaction forms part of Howden’s wider strategy to scale specialist capabilities in key growth markets, particularly the US, where deal activity continues to drive demand for sophisticated insurance solutions.
Founded in 2017 and headquartered in New York, Atlantic Global Risk has grown rapidly to become a top five broker in the North American transaction liability market.
The firm operates across four core lines: representations and warranties insurance, tax liability insurance, contingent risk insurance and credit risk insurance. Backed by a team of more than 110 specialists, Atlantic Global Risk supports clients across the US, Canada and Latin America, with a strong focus on private equity-backed transactions.
Howden, meanwhile, has built a reputation as the largest transaction liability insurance broker outside the US, combining global reach with deep sector expertise.
The group has been actively expanding its US footprint, adding hundreds of industry specialists across multiple practice areas and cities since August, as it seeks to replicate its international success in the world’s largest insurance market.
The combination of Howden and Atlantic Global Risk creates a new global force in transaction liability insurance, bringing together international scale and deep US market expertise.
As part of the deal, Atlantic Global Risk’s founders will take on key roles within Howden’s US retail broking business and global transaction liability strategy. They will also become Howden shareholders, signalling long-term strategic and cultural alignment between the two organisations.
The transaction has been approved by the boards of both companies and remains subject to customary closing conditions. It is expected to complete in the first quarter of 2026.
Howden founder and CEO David Howden said, “Howden’s growth has been driven by attracting the industry’s most talented and entrepreneurial people and then empowering them to deliver exceptional expertise and service to clients. The addition of Atlantic Group is another powerful example of this talent-focused approach. In just a few years, Atlantic has established itself as one of the top five brokers in its field with a fantastic reputation. The team shares our DNA and passion for clients and the founders – Richard, Joe and David – have chosen to reinvest a substantial portion of their equity, joining us on our journey to build a company like no other.
“By combining our international transactional liability leadership with Atlantic Group’s deep US expertise, we are creating a global powerhouse which will open up huge opportunities to support the world’s leading private equity houses and their portfolio companies. This is a cornerstone acquisition for Howden in the US, which allows us to deliver even greater expertise and excellent service to our clients.”
Howden in the US CEO Mike Parrish said, “This is a transformative partnership for a few primary reasons. First, unmatched talent and expertise. Large-scale M&A doesn’t happen without transactional liability insurance, and the Atlantic team understands that space at a level that others do not. Second, breadth, depth, and access. We’re uniting the largest transactional liability broker outside the US with the preeminent transactional liability team in the global epicentre of M&A and private equity. Third, cultural alignment. Atlantic’s ambitious, client-first culture is a perfect match for us. They thrive in competitive, complex transaction environments, building coverage around clients, not products. That’s how we work at Howden. I am thrilled to welcome David, Joe, Richard, and everyone at Atlantic to Howden and our growing, dynamic team in the United States.”
Atlantic Global Risk founding partner David Haigh said, “This is an exciting next step in our journey, and we’re delighted to be rejoining the platform that launched our careers in this space. This agreement unites two organisations that are entirely client-centric and who pride themselves on being thoughtful, like no other, and with collaborative approaches that ensure clients get best-in-class expertise and solutions. By combining our transaction liability practice with Howden’s existing capabilities, global reach and resources, our clients will now benefit from a broader product offering, access to many more like-minded experts and the ability to be serviced across more geographies than I am capable of naming. We look forward to putting the power of this collective to the test to see what we can bring to clients and the insurance market in the future.”
