Bamboo Pioneers MGA-Sponsored Sidecar Expansion with Accredited to Launch E&S Signature in Texas

MIDVALE, Utah, Sept. 30, 2025 /PRNewswire/ -- Bamboo Ide8 Insurance Services, LLC. ("Bamboo"), part of White Mountains Insurance Group, Ltd. (NYSE: WTM), and specialty insurer Accredited have announced the completion of the reinsurance program supporting the launch of their new E&S Signature program. This reinsurance placement includes the funding of a multi-year sidecar transaction through Greenshoots Re Ltd. ("Greenshoots Re") that was originally established in conjunction with Bamboo's renewal of another program in early 2025.

John Chu, CEO of Bamboo, commented: "Greenshoots Re was first used to bring complementary capital markets capacity to another program's traditional reinsurance panel earlier this year. However, our broader goal was to create a flexible, long term strategic capital vehicle providing incremental capacity access for both new and existing programs. The Accredited transaction is validation of this thesis, and we appreciate their support and recognition of this capability as we jointly launch E&S Signature and Texas. Greenshoots Re is a clear strategic differentiator for us, providing turn-key capital markets access and looking ahead we see numerous applications to expand its use."

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

Liam Martens, Managing Director of GC Securities, said: "We're proud to have supported Bamboo on another sidecar issuance. We continue to see healthy investor interest in Bamboo's underwriting platform and the Greenshoots Re franchise. We believe the Greenshoots Re franchise is unique insofar that it is the first MGA sponsored sidecar vehicle to have faced multiple unaffiliated cedants and will look to further extend its use in providing meaningful fully collateralized reinsurance support for additional Bamboo programs in the near future."
