Miller reports fifth year of growth

Miller reported another year of growth, with revenue rising 15% to £314 million for 2025, marking its fifth consecutive year of expansion. The firm placed around $5 billion in gross written premium and grew headcount to more than 1,300 employees after adding 180 hires.

Growth was driven by a mix of acquisitions and geographic expansion. Miller acquired reinsurance broker AHJ, strengthening its treaty capabilities and adding exposure to Nordic, Caribbean, and North American markets. It also completed the integration of Spanish broker Bruzon and continued to build out its presence in Asia, including launching operations in Korea and expanding into Japanese non-marine lines.

The company is continuing that strategy into 2026, with the planned acquisition of Shields Reinsurance, which would extend its reach into the MENA region and add local market access.

Alongside expansion, Miller introduced a new brand identity under the tagline “Go Be Great” and launched new solutions such as MillerBoost, a property-focused smart follow facility. The firm also highlighted ongoing investment in talent, including senior MGA leadership hires.

Management framed the strategy as selective growth rather than scale for its own sake, focusing on adding capabilities, expanding distribution, and strengthening its position as a specialist broker with international reach.
