Miller, an independent specialist insurance and reinsurance broker, has announced the appointment of Peter Stubbings as CEO of Reinsurance, alongside Gary Masters as Chairman of Reinsurance.
Stubbings brings more than four decades of reinsurance and leadership experience, broad technical expertise and long-standing client relationships across London, Bermuda, the Caribbean and the Nordics.
He joined Miller in May 2026 as Chairman of Miller Bermuda, where he has played a key role in developing Miller’s Bermuda reinsurance and retrocession proposition.
In his role as Chairman of Reinsurance, Masters will continue to help shape the strategic direction of the business, working closely with Stubbings to ensure continuity and a smooth leadership transition.
Miller said the new leadership structure marks the next phase of its reinsurance growth, as it continues to establish a global, specialism-led reinsurance business.
A key focus will be bringing together Miller’s established capabilities with those of its recent acquisitions, including Miller Bruzon, AHJ Miller and Shields Miller. These acquisitions have deepened its treaty expertise and extended its geographical footprint across the Nordics, Caribbean, North America and the MENA region.
James Hands, CEO of Miller, said, “We have built real momentum in reinsurance, with significant progress in our teams, capabilities and international footprint. Peter’s appointment as CEO of Reinsurance, alongside Gary’s transition to Chairman, gives us a strong leadership partnership for this next chapter. Peter brings exceptional market experience, technical depth and client relationships and I am also delighted that we will continue to benefit from Gary’s experience and strategic insight as Chairman, having made a significant contribution to the development and growth of Miller’s reinsurance business since joining Miller through the AHJ acquisition.”
Stubbings added, “The opportunity ahead is incredibly exciting. We have an exceptionally strong platform for the future, built on talented people, technical expertise and deep client relationships. My focus now is on building on that foundation to help serve clients even more effectively in a complex risk environment, working closely with colleagues across both our reinsurance and insurance teams at Miller.”
