Read MoreHide Full Article

Key Takeaways

  • AJG is acquiring Winter & Co to expand Gallagher Bassett's marine claims and risk management capabilities.
  • Winter & Co adds maritime law expertise serving P&I clubs, marine insurers, shipowners and charterers.
  • AJG gains a stronger London and EMEA presence while supporting its acquisition-led Risk Management growth.

Arthur J. Gallagher & Co. (AJG - Free Report) is expanding its specialty risk management capabilities by acquiring Winter & Co Solicitors LLP, a London-based maritime law firm. Financial terms were not disclosed.

Winter & Co specializes in maritime law and serves P&I clubs, marine insurers, shipowners and charterers. Its expertise will complement Gallagher Bassett's existing marine claims and risk management operations.

The acquisition falls under Gallagher Bassett, part of AJG's Risk Management segment, which reported 16% revenue growth in the second quarter of 2026, while fees increased to $445 million from $383 million. Management attributed the performance to strong new business and client retention, as customers increasingly seek broader risk-management solutions.

The deal also strengthens Gallagher Bassett’s presence in London and the broader Europe, Middle East and Asia market, allowing AJG to add specialized maritime expertise without having to build the capability internally. This aligns with AJG’s broader strategy of using acquisitions to deepen expertise and expand its service offerings across specialized markets.

Financially, Winter & Co is unlikely to materially affect near-term results given the undisclosed transaction terms and its specialist profile. However, the added capability could expand the services Gallagher Bassett offers to marine clients and create opportunities to generate additional fee revenues from claims, legal and risk management services.

Overall, the acquisition adds another niche capability to AJG’s growing fee-based Risk Management platform, supports its acquisition-led growth strategy, while potentially strengthening client relationships and incremental earnings over time.
