The Fidelis Partnership has launched Adroit Underwriting, a new Bermuda-based managing general agent focused on US small and medium enterprise casualty reinsurance. Adroit was launched through Pine Walk, Fidelis's specialist MGA platform.
The company will underwrite reinsurance across several US casualty lines. Those lines include medical malpractice, cyber liability, general liability, construction risks for architects and engineers, public entity, D&O/E&O and lawyers' professional liability.
Capacity will come from Fidelis's Syndicates 3123 and 2126, along with third-party carriers. Syndicate 3123 was established at Lloyd's in 2024 and wrote about $200 million of gross premium in its first six months.
Comparable specialty niches give some sense of scale. Pine Walk launched an MGA focused on accident and health reinsurance in 2025. At the time, the company noted that class alone represents more than $7 billion in annual premium globally.
Adroit is not Pine Walk's first casualty-focused MGA. Pine Walk launched Sevanta, an international casualty MGA, in 2025. The publicly listed Fidelis Insurance Group declined to provide capacity to that cell.
It said casualty was outside its risk appetite at the time. The release announcing Adroit does not name Fidelis Insurance Group among its capacity providers either.
Jeff Markowski will serve as Adroit's CEO and chief underwriting officer. He has more than 20 years of experience in US casualty treaty underwriting, most recently as director of underwriting at Peak Re's North America operation.
Derrick Holmes will serve as chief financial officer and chief operating officer. Holmes has more than a decade of reinsurance finance and operational experience. That includes responsibility for agent operations at Peak Capital and experience in the insurance-linked securities market.
Adroit is Pine Walk's 18th business launched on its platform. Pine Walk executives said in late 2025 that the platform's gross written premium was on track to exceed $1.2 billion for the year. That projection came as the platform reached its 16th MGA.
The platform ultimately wrote about $1 billion in premium across 16 cells for full-year 2025. That was up from $0.9 billion across 11 cells in 2024. Five new MGAs were added during the year, including a casualty-focused cell.
Michael Davern, Fidelis's UK chief underwriting officer, said Pine Walk gives Adroit access to underwriting, operational and regulatory support. He said the platform also offers cross-selling opportunities across Fidelis's broader business.
Markowski said the US SME casualty reinsurance market lacks enough specialist underwriters with established relationships. "The US SME casualty reinsurance market is underserved by specialist underwriters with the depth of relationships and track record to move quickly and with conviction," Markowski said.
