Macro View

For the average client, these acquisitions can lead to broader service offerings and increased professional expertise within their local area. However, consolidation may also reduce the number of independent options available for businesses seeking specialized insurance broking services.

The takeaway

The insurance sector continues to favor consolidation as a primary engine for corporate growth and scale. Business leaders in fragmented industries should anticipate further acquisition activity as firms look to secure professional talent and books of business.
