Arrow Global Insurance has agreed to acquire Fusion Specialty Group, a global MGA specialising in warranty and indemnity, tax liability and contingent risk insurance, with completion expected in Q3 2026 following receipt of all required regulatory approvals. The commercial timing is specific: Gallagher reported that average W&I and R&W quoted rates rose from 2.5% in Q4 2024 to 3.23% in Q4 2025 as claims volumes increased, and Marsh recorded a 34% rise in global transactional risk insurance limits placed in 2025 to a record US$91.6 billion. Acquiring a specialist W&I MGA at the point where the rate cycle is firming and claims volumes are rising gives Arrow a platform position in a segment that rewards underwriting discipline over price competition.
The Halldora Re arrangement is the most analytically significant deal mechanic. Fusion will join a platform where MGAs access rated reinsurance capacity from Halldora Re Ltd, an A- (Excellent) AM Best-rated reinsurer. Arrow described the structure as reducing MGAs' dependence on external capacity cycles - the volatility in availability and pricing that affects specialist lines when market conditions shift. For an independent W&I MGA, securing consistent capacity through a soft market or a period of elevated claims is a structural vulnerability; the Halldora Re arrangement removes that exposure.
Katie Simmonds, chief executive of Fusion, said access to additional capacity through Halldora Re, together with Arrow's long-term investment approach, "provides a strong foundation for our next phase of growth while allowing us to remain focused on the underwriting discipline and client service that define Fusion." Fusion's existing management team is expected to continue in their roles following completion, and David Rogers, founder and executive chairman, will remain involved with the business.
Fusion was established in Australia in 2018 and has since written approximately £290 million in GWP for roughly 1,500 policyholders across more than 30 countries, with underwriting hubs in the UK, US, Canada, Germany, Australia, Singapore and Hong Kong. The MGA has processed more than 23,000 submissions and premium volume more than doubled over the past two years.
Fusion also operates Mio, a technology-driven transaction liability solution for SME deals currently available in the UK, US, Australia and New Zealand. The SME segment represents a specific market gap in W&I: traditional warranty and indemnity underwriting economics do not scale cost-effectively to smaller deal sizes, leaving the segment underserved by standard MGA propositions. Mio is designed to address that gap through a technology-led model that reduces the manual underwriting burden on smaller transactions - a distribution capability that complements Fusion's mid-market and larger deal book rather than competing with it.
Zach Lewy, chief executive officer of Arrow Global Group, said the acquisition expands the range of specialty insurance opportunities available to the group's institutional investors, describing AGI as a platform combining specialty underwriting businesses with long-term institutional capital from Arrow Global Group, a pan-European alternative investment manager. Fusion will become a subsidiary of Sherwood Topco Limited on completion, funded by capital from shares issued by Sherwood Topco and funds managed by Arrow Global Group.
The deal fits a pattern now well established in UK specialty distribution. More than a quarter of UK insurance distribution deals in H1 2026 involved a specialty target - the highest proportion on record per MarshBerry data - as new MGA formation continues to outpace consolidation in commercial broking and sustains specialist deal flow.
