Underwriting Consortium

RBC Capital Markets, UBS Investment Bank, and Raymond James will act as lead book-running managers for the offering. Goldman Sachs & Co. LLC, Deutsche Bank Securities, Citizens Capital Markets, and Texas Capital Securities are designated as book-running managers.

Business Profile and Scale

Founded in 2018, Orion180 has grown organically to become the second largest excess and surplus (E&S) lines homeowners insurance provider in the United States by direct written premiums. The company maintains a presence in 14 states and distributes its diverse product offerings through a network of more than 14,000 active independent agents as of June 30, 2026.

Its portfolio includes E&S and admitted homeowners’ insurance, private flood insurance, and ancillary products. The business model relies on four core principles: innovation, real-time data-driven decision-making via its proprietary MY180 platform, ease of doing business, and long-term partnerships with distribution and reinsurance providers.

Orion180 Insurance launched its Residential Private Flood Insurance in California on Aug. 4, 2026, introducing a customizable alternative to the National Flood Insurance Program (NFIP) for homeowners facing rising flood risks. The product provides up to $1 million in building coverage with waiting periods as short as 10 days, significantly exceeding the NFIP’s $250,000 cap and standard 30-day wait. This launch addresses a critical gap in the market, where less than 2% of California homeowners currently hold flood insurance, despite projections that major cities like Los Angeles, San Diego, and San Francisco will face higher flooding risks within the next 25 years due to atmospheric rivers, urban development, aging infrastructure, and wildfire burn scars.

The new policy leverages data-driven underwriting that utilizes advanced third-party flood mapping and property-specific risk assessments, moving beyond the conventional Federal Emergency Management Agency (FEMA) flood maps. This approach allows for more accurate pricing and broader protection across X, A, and V flood zones. Unlike traditional options, most homeowners can obtain coverage without needing elevation certificates, extensive paperwork, or additional property inspections, streamlining the application process.

Key Product Features

The Residential Private Flood Insurance is designed to meet FMAC and FNMA mortgage requirements, ensuring smooth approval by lenders. The policy includes several enhanced features tailored to California’s unique environmental challenges:

Market Context and Strategy

Ken Gregg, CEO of Orion180, highlighted that flooding is an increasingly serious issue for homeowners across California, even in areas not traditionally considered high-risk. "Too many homeowners are either uninsured or limited to costly policies with no flexibility," Gregg said. "Our goal is to simplify the process, provide more competitive pricing, and deliver protection that reflects a homeowner’s real flood exposure and not just their zone."

CoreLogic projects that within the next 25 years, environmental changes will extend residential flooding predictions beyond typical high-risk zones. Orion180 aims to capitalize on this shift by offering a solution that combines proprietary technology with real-time data. The company operates as a surplus lines insurer in California and other states, while also functioning as an admitted insurer in select markets. Homeowners can now secure this flood protection alongside their Orion180 FLEX home insurance policies.
