Credit rating agency AM Best has extended Hadron group’s Financial Strength Rating of A- (Excellent), Financial Size Category VIII, to The Guarantee Company of North America USA (GCNA).

According to the announcement, this approval reflects AM Best’s recognition of Hadron’s consolidated capitalization, disciplined underwriting framework, and strong governance across its expanding platform.
“AM Best’s decision to include GCNA under Hadron’s group rating is an important step in our continued growth,” said Sam Reeder, CEO of Hadron. “It reinforces the financial strength of Hadron’s platform and the confidence in the way we are building a modern, data-driven carrier that provides stability and transparency for our MGA and reinsurance partners.”
The inclusion of GCNA under the group rating bolstered Hadron’s admitted platform, which complements its existing Excess & Surplus (E&S) capabilities.
This allows the carrier to offer a broader range of product solutions across the US and international markets, including a new expansion into the traditionally underserved surety segment.
Hadron’s A- (Excellent) rating highlights the company’s balance-sheet strength, experienced underwriting team, and technology-enabled oversight that supports its mission to modernize the delegated authority market.
Backed over $250 million in committed capital from Altamont Capital Partners and other investors, Hadron continues to strategically expand while maintaining underwriting discipline and transparency across its operations.
The company is currently writing business in the US and UK and has plans for future platform expansion to meet continued demand in the delegated authority market.
“This ratings alignment confirms Hadron’s momentum and long-term vision,” added Reeder. “We’re building a financially strong, well-governed carrier that partners can consistently rely on that is designed to evolve with the needs of the specialty insurance ecosystem.”
