• Completed acquisition of specialist reinsurance broker AHJ, providing immediate scale and capability in Treaty reinsurance and giving Miller access to AHJ’s strong positioning in Nordic, Caribbean and North American Treaty markets.
• Completed integration and brand transition of Spanish operations following 2024 acquisition of Spanish broker Bruzon, now fully operating under the Miller brand.
• Unveiled new brand and visual identity under the tagline “Go Be Great”, reinforcing client-first philosophy and the role insurance can play as an enabler for clients and society.

Commenting on Miller’s results, James Hands, CEO, said: “2025 has been another milestone year for Miller as we deliver a fifth consecutive year of profitable growth. This reflects our efforts to strengthen our proposition for clients and insurance capacity providers through a broader product range, increased geographic reach and continuous improvement of client service.  

Last year, we significantly expanded our footprint by both capability and geography with the acquisition of AHJ, marking a step change in the scale of our reinsurance platform. We also successfully integrated Spanish broker Bruzon and continue to be one of the fastest-growing players in Asia, including launching Miller Korea and diversifying into Japanese non-marine lines.  

We are already building on this momentum and have further expanded our multinational presence with the acquisition of Shields Reinsurance at the beginning of 2026 (subject to regulatory approval), enhancing our offering and reach in MENA and giving us a local presence to further serve new and existing clients. 

However, Miller’s goal has never been growth for growth’s sake, and we continue to focus on opportunities where we can build our platform by bringing true value, establishing an international footprint that reflects and complements our profile as one of the most highly regarded specialist brokers in London. 

Having unveiled our new brand under the tagline “Go Be Great” at the beginning of last year, we continue to demonstrate unwavering commitment to innovation, client service excellence, and to nurturing the industry’s greatest talent. We welcomed 180 new employees to our business and have continued to diversify our offering, strengthening our specialist expertise with key new hires, including the appointment of an MGA CEO and CUO, while launching innovative client solutions such as MillerBoost, our advanced Property smart follow facility.

Looking ahead, we are excited by our future growth and believe more passionately than ever that our combination of independence, specialism and international scale makes Miller a uniquely attractive proposition for both our clients and our colleagues.
