Howden strengthens transaction liability platform with Atlantic Group acquisition

Howden has agreed to acquire Atlantic Global Risk, creating a global transaction liability platform spanning the US, Europe and other major M&A markets.

The latest deal brings together the largest transaction liability broker outside the US with one of the leading specialists in North America, significantly expanding Howden’s capabilities in representations and warranties and related lines.

Howden said the acquisition will accelerate the growth of its US retail platform and reinforce its position in transaction liability insurance globally.

Atlantic Global Risk LLC was established in 2017 and is headquartered in New York.

The business has grown rapidly to become a top five broker in the North American transaction liability market.

Atlantic Group provides cover across representations and warranties, tax liability, contingent risk and credit risk insurance.

Its team of more than 110 specialists serves clients across the US, Canada and Latin America.

The transaction adds further scale to Howden’s US expansion, which has seen hundreds of industry professionals join the group across multiple cities and practice areas since August.

Atlantic Group’s founders will take on senior roles within Howden’s US retail broking business and global transaction liability strategy.

They will also become shareholders in Howden, alongside most of Atlantic Group’s employees, reflecting what both sides described as a strong cultural alignment.

David Howden, founder and CEO of Howden, said the acquisition was consistent with the group’s talent-led growth strategy.

“In just a few years, Atlantic has established itself as one of the top five brokers in its field with a fantastic reputation,” he said.

“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.”

Mike Parrish, CEO of Howden US, said the combination brought together unmatched expertise and scale in a market central to global M&A activity.

“We’re uniting the largest transactional liability broker outside the US with the preeminent transactional liability team in the global epicentre of private equity,” he said.

David Haigh, founding partner of Atlantic Group, said the deal marked a natural next step for the business.

“By combining our transaction liability practice with Howden’s 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,” he said.

The transaction is subject to customary closing conditions and, according to Howden, is expected to complete in the first quarter of 2026.
