Optio Group has completed its acquisition of Gardian Marine Limited following all necessary regulatory approvals, adding a London-based marine builders' risk and liability specialist to a platform that has now made four acquisitions across the European marine and specialty market in the past year. The deal was first announced in March.
The four-acquisition pattern is the analytical story. Optio's purchases of Norwegian marine hull specialist S Insurance, Luxembourg-based special risks MGA Circles Group, Netherlands and Brussels-based Den Hartigh and now Gardian Marine collectively point to a specialty MGA sector where scale and product breadth, rather than organic growth alone, are the route to competing for capacity and broker relationships in a market where the underlying commercial logic strongly favours acquisition. Delegated authority premiums at Lloyd's rose from £10.4 billion in 2018 to £22.1 billion in 2023, taking their share of Lloyd's premium income from 30% to more than 40%, with that share expected to exceed 45% by 2027 per Oxbow Partners. For MGAs such as Optio, that growth underpins the case for acquiring established coverholders with deep underwriting expertise rather than building capability from scratch - each acquisition buys existing broker relationships, proven capacity arrangements and demonstrated underwriting track records that organic growth cannot replicate at the same speed.
Gardian Marine specialises in marine builders' risk insurance, ship repairers and liability, voyage and towage insurance, and bespoke ancillary products, backed by Lloyd's and A-rated insurer capacity. It is led by co-founders Guy Tyler and Edward Morgan, both of whom remain with the business. Tyler and Morgan previously served as directors at WTW, with Tyler overseeing International Hull and Machinery and Morgan leading Special Risks, bringing 28 years of combined builders' risk experience for shipyards and vessel owners. The acquisition extends Optio's marine offering, which now spans hull, cargo, war and shipbuilding risks.
Optio's chief executive Deepak Soni described Gardian Marine as having rapidly evolved into a respected and disciplined business driven by Tyler and Morgan's market-leading expertise and strong networks, adding that the cultural alignment and entrepreneurial foundations made it the right fit for developing the next stage within Optio. Tyler said the combination gives Gardian Marine the scale and resources to deepen capabilities while preserving the agility its clients rely on.
The deal completes at a sensitive moment for the marine war risk market that Gardian Marine's products touch on. War risk premiums in the Gulf have surged 340% since Iranian strikes at the end of February 2026, after the Lloyd's Joint War Committee expanded its designated high-risk area to cover the entire Persian Gulf following US and Israeli military strikes on Iran that month. The Lloyd's Market Association has said the disruption to vessel traffic reflects shipowners' own safety assessments rather than a lack of available cover, with the large majority of Lloyd's marine war market participants surveyed retaining appetite to underwrite hull and cargo war risks linked to the region. For MGAs building out war risk capacity, the episode illustrates how quickly pricing and capacity conditions in that line can move - and how central the London market remains to pricing global marine war risk.
Optio's task now is integrating Gardian Marine's builders' risk and liability expertise into a platform already managing exposure across some of the most volatile corners of the marine market, at a time when Lloyd's delegated authority channel is taking on a larger share of the market's business and capacity providers are watching war risk pricing closely.
