Leadership appointments

Specialist insurance and reinsurance broker Miller has appointed Peter Stubbings as CEO of Reinsurance and Gary Masters as Chairman of Reinsurance. Stubbings joined Miller in May 2026 as Chairman of Miller Bermuda, bringing over four decades of experience across London, Bermuda, the Caribbean and the Nordics. Masters, who joined through the acquisition of AHJ, will transition from his previous role to focus on strategic direction and leadership continuity alongside Stubbings.

Reinsurance growth strategy

According to Miller CEO James Hands, the leadership changes support the next phase of the firm's reinsurance expansion. The strategy centers on integrating established capabilities with recent acquisitions including Miller Bruzon, AHJ Miller and Shields Miller, which have extended the broker's treaty expertise and geographic footprint across North America, the MENA region, the Caribbean and the Nordics.

Why it matters

The executive changes formalise a new leadership partnership designed to integrate Miller's recent acquisitions—such as Miller Bruzon, AHJ Miller and Shields Miller—into a unified global reinsurance platform.

Jargon, explained
