SageSure Scales Seawall Re Sidecar Franchise; Secures $200 Million in Reinsurance

Audio By Carbonatix

JERSEY CITY, N.J.--(BUSINESS WIRE)--Mar 10, 2026--

SageSure, the largest residential property MGU in the US specializing in catastrophe-exposed markets and a top global sponsor of catastrophe bonds, today announced the close of its second reinsurance sidecar transaction with Seawall Re II Ltd. (“Seawall Re II”), securing $200 million in capital.

In conjunction with its carrier partners, SageSure programs are expected to secure approximately $7 billion of first event reinsurance limit in 2026.

Including the debut Seawall Re transaction in July 2025, the SageSure-sponsored sidecar platform has now secured $250 million in less than a year. This rapid expansion underscores SageSure’s pioneering role in the convergence of reinsurance capital and capital markets in the catastrophe risk space, a strategic priority as the company continues to mature the insurance-linked securities (ILS) asset class for institutional investors.

“SageSure is committed to building long-term investor relationships, and Seawall Re II is a direct reflection of that commitment,” said 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.”

This transparency facilitates a quota share structure that creates alignment between capital providers, SageSure, and SageSure’s underwriting partners SURE, Elevate, SafeChoice, Auros, Interboro, and GeoVera Nova. Carrier partners benefit from incremental catastrophe capacity and reduced net risk positions, while capital providers gain access to a well-priced, well-managed, and diversified catastrophe risk portfolio.

GC Securities, a division of MMC Securities LLC, acted as the sole structuring and placement agent for the sidecar transaction. Willkie Farr & Gallagher LLP served as deal counsel.

“We’re proud to have partnered with SageSure on the Seawall Re platform since its inception,” said Liam Martens, Managing Director of GC Securities, a division of MMC Securities LLC. “The strong investor response signals SageSure’s differentiated approach to catastrophe risk management is highly attractive to the capital markets. We look forward to building on this momentum as the Seawall Re franchise scales.”
