By GlobalDataPrimeOne president David Thorson said: “Partnering with Gryphon provides PrimeOne with long-term strategic capital and a broader platform to expand our underwriting capabilities while maintaining the discipline and client focus that define our business.
“We see this transaction as an opportunity to accelerate growth, deepen reinsurance relationships, and create new opportunities for our clients and partners.”
Gryphon Holdings is backed by Phoenix Merchant Partners and provides capacity for insurance and reinsurance as well as investment in specialty markets.
With the addition of PrimeOne, Gryphon’s platform will extend to MGA incubation, third-party claims and policy administration services, asset management for insurance-linked investments, and increased insurance and reinsurance capacity through its internal carrier model.
The deal completion is expected in the first quarter of 2026, pending approval from regulators.
Gryphon CEO Erin Brennan Bagley commented: “We are excited to welcome PrimeOne into the Gryphon enterprise.
“This acquisition accelerates our vision of creating a unified platform where investors and insurance market participants can connect, innovate and thrive. PrimeOne’s reputation and capabilities will be key assets as we continue to build out our specialty insurance, asset management and bespoke reinsurance capacity solutions.”
This move follows news of the planned acquisition of Concert Group by Freedom Underwriters, another entity backed by Gryphon and its original investors.
