Hadron Completes Acquisition of The Guarantee Company of North America USA, Expanding Its Admitted Platform Capabilities

Strategic acquisition positions Hadron as a top-tier carrier in the delegated authority market

LITTLE ROCK, Ark.--(BUSINESS WIRE)--Hadron, a modern insurance carrier focused on innovation in the delegated authority space, today announced the successful completion of its acquisition of The Guarantee Company of North America USA (GCNA) from Atlantic Specialty Insurance Company, a subsidiary of Intact Financial Corporation (TSX: IFC).

This acquisition — Hadron’s second since inception — expands upon the company’s specialty reach, adding new admitted product opportunities across its U.S. platform and accelerating its growth trajectory more broadly.

“Today marks a pivotal milestone in Hadron's journey to modernize the insurance value chain,” said Sam Reeder, CEO of Hadron. “GCNA's broad nationwide admitted licensing and surety capabilities position us to deliver solutions that meet the evolving needs of the delegated authority market. I’d like to thank my colleagues for their tireless efforts in building Hadron with unwavering commitment to excellence, at a pace and scale that is enviable.”

“Hadron's execution has been exceptional,” said Sam Gaynor, Managing Director of Altamont Capital Partners. “In just over 18 months since launch, they've accomplished what peers typically take five or more years to build — achieving diversified scale and strong operational foundations.”

The acquisition brings licensing in all 50 U.S. states, Washington, D.C., and Puerto Rico, plus Certificate of Authority from the U.S. Department of Treasury for Federal surety bonds, significantly expanding Hadron's capabilities. The company’s team of industry experts will leverage these enhanced capabilities through Hadron's data-first approach and leading technology platform.

Backed by more than $250M in committed capital and rated A- (Excellent) by AM Best, this acquisition reinforces Hadron's position as one of the most dynamic carriers in the specialty insurance market, setting new standards for growth and innovation.
