SageSure, the specialist catastrophe-exposed property managing general underwriter (MGU), has sponsored its second collateralized reinsurance sidecar, securing $200 million of protection from a Seawall Re II Ltd.transaction.In July 2025, we reported that securing $50 million of third-party retro support from investors for its captive reinsurance vehicle Anchor Re.In turn that protection cascades down to benefit a number of SageSure linked underwriting entities.

It’s not immediately clear if the same is true of this second sidecar arrangement is structured the same, to provide retrocession to Anchor Re and then benefit SageSure underwriting entities with reinsurance.But Seawall Re II does see SageSure significantly expanding the amount of quota share reinsurance it receives from its sidecar platform, so expanding its utility while still covering multiple underwriting vehicles, it seems.As a result of this much larger sidecar arrangement, SageSure has now secured $250 million of reinsurance limit from third-party investors through its Seawall reinsurance sidecar platform.

“SageSure is committed to building long-term investor relationships, and Seawall Re II is a direct reflection of that commitment,” explained Terrence McLean, President and CEO of SageSure.“We believe that the future of catastrophe risk management lies in the ability to provide investors with a transparent, data-driven gateway to profitable underwriting results.We look forward to continuing to build investor trust with high-quality data, proactive reporting, and sustained outperformance.” Working closely with carrier partners and benefiting from both traditional reinsurer and capital market or ILS investor appetite, SageSure said that for 2026 it expects to secure approximately $7 billion of first event reinsurance limit.
