Mountain Re Ltd. (Series 2026-1) Class A Notes

Company and Transaction Overview

On May 15, 2026, Hippo Holdings’ programs carrier, Spinnaker Insurance Company (“Spinnaker”), sponsored its second 144A Cat Bond issuance through its Bermuda-domiciled SPV, Mountain Re Ltd.

Mountain Re Ltd. provides Spinnaker per-occurrence, indemnity-triggered event coverage through this transaction.

The transaction featured a wildfire contribution to expected loss of 70%, with the vast majority of the exposure centered in California.

Despite these factors, the Series 2026-1 Notes garnered significant support from investors, with oversubscription driving pricing to a 7.25% spread — 50 basis points below the low end of initial price guidance.

Spinnaker’s unique and proven underwriting strategy helped it achieve its targeted amount.

  • Spinnaker had exposure to the recent LA wildfires and coastal exposure to Hurricane Ian, and yet suffered minimal losses on both accounts.
