Miller Appoints Peter Stubbings & Gary Masters
Miller has appointed Peter Stubbings as CEO of Reinsurance and Gary Masters as Chairman as the company advances its global reinsurance growth strategy.
A spokesperson said, “Miller, the independent specialist [re]insurance broker, is pleased to announce changes to its Reinsurance leadership team. Peter Stubbings has been appointed as CEO of Reinsurance, and Gary Masters will become Chairman of Reinsurance.
“The appointments reflect the scale, momentum and ambition of the business following significant growth, team expansion and the acquisitions of Miller Bruzon, AHJ Miller and Shields Miller.
“Peter 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 been instrumental in building Miller’s Bermuda reinsurance and retrocession proposition.
“As Chairman, Gary will continue to help shape the strategic direction of the business, working closely with Peter to ensure continuity and a seamless handover.
“The new leadership structure marks the next phase in Miller’s reinsurance growth, as the firm continues to establish a global, specialism-led reinsurance business. The focus will be on further bringing together Miller’s established capabilities alongside recent acquisitions which have deepened its treaty expertise and extended its geographical footprint into the Nordics, Caribbean, North America and the MENA region.”
James Hands, CEO, 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.”
Peter Stubbings, CEO of Reinsurance, Miller, 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.”
The spokesperson said, “Both appointments are subject to regulatory approval.”
