Ryan Specialty has completed its acquisition of the business of J.M. Wilson Corporation, a Michigan-based managing general agency.
The transaction, originally announced on June 5, will see JM Wilson integrated into RT Binding Authority, the binding authority division of Ryan Specialty.
Founded in 1920, JM Wilson operates six offices across the US and provides a range of products including personal lines, surety and transportation coverage. The firm has established long-term relationships with carrier partners, particularly in the transportation segment, where it has maintained underwriting profitability.
“We are thrilled to join RT Specialty and are very familiar with the team,” said David Wilson, president of JM Wilson. “For the past 100 years, we have prided ourselves in developing top talent and competing on expertise. Culturally, we know that Ryan Specialty shares our values. We look forward to the future as a part of the Ryan Specialty family.”
JM Wilson reported about $19 million in operating revenue for the 12 months ending January 31, 2025. Financial terms of the dela were not disclosed. The transaction was expected to close in Q3 2025.
Philo Smith served as exclusive financial advisor to JM Wilson.
The deal comes as Ryan Specialty continues to expand its specialty lines business. In June 2025, the firm announced the formation of Ryan Specialty Renewables, a new business unit that consolidates its renewable energy underwriting operations.
The unit brings together managing general underwriters PERse Americas, PERse International, internal startups and Albus – a renewable energy-focused MGA previously part of Castel Underwriting Agencies, which Ryan Specialty acquired in May 2024. The integration process is scheduled to continue through H2 2025.
