Ryan Specialty, an international specialty insurance firm, has signed a definitive agreement to acquire J.M. Wilson Corporation, a Michigan-based insurance business.

Upon deal closing, J.M. Wilson’s operations will be integrated into RT Binding Authority, the binding authority segment of Ryan Specialty.

Founded in 1920, J.M. Wilson operates six offices across the US. The company offers a wide range of products, including personal lines and surety, with a particular focus on transportation insurance. J.M. Wilson’s reputation in the transportation sector is supported by its historical underwriting profitability and longstanding relationships with carriers. It generated approximately $19 million in operating revenue for the 12 months ended Jan. 31, 2025.

Ed McCormack, CEO of RT Specialty, said JM Wilson is recognized in the industry for its underwriting track record and client focus. He noted that the acquisition strengthens RT Specialty’s presence in the Midwest and enhances its transportation practice.

Meanwhile, David Wilson, president of J.M. Wilson, said the company is looking forward to joining RT Specialty. He noted the similar values the companies share, adding that his team is familiar with RT Specialty’s operations.

Terms of the deal were not disclosed. The transaction is expected to close in the third quarter of 2025.

In separate news, RT Specialty has opened an office in Detroit and appointed David Derigiotis (pictured immediately above) as executive vice president and office president. Derigiotis will lead RT ProExec, RT Specialty’s professional and executive liability practice group.

Ed McCormack commented that Detroit is a growing market for RT Specialty and that Derigiotis’s expertise in cyber, professional, and management liability insurance will support the company’s growth and service efforts in the region.

Derigiotis said he has long respected RT Specialty and is looking forward to contributing to the company’s growth and client service initiatives.
