Homeowners and flood insurance provider Orion180 Insurance Group has filed a Form S-1 with the US Securities and Exchange Commission for a proposed initial public offering of its Class A common stock.
The firm is looking to raise up to $100m from the offering. However, the filing has not yet determined the number of shares to be offered or the price range.
Orion180 provides excess and surplus home insurance concentrated in the US Southeast. It reported approximately $601m in managed premiums written for the twelve months ending 30 June 2026, and has sold more than 670,000 policies since inception. The firm offers E&S and admitted homeowners’ insurance, private flood insurance, and a range of ancillary products, all distributed through a network of independent agents.
Its book skews towards higher-risk geographies. In 2025, 51% of its managed written premiums were for traditional non-admitted products, focused on coastal and catastrophe-exposed properties.
Orion180 has applied to list its Class A common stock on the Nasdaq Global Select Market under the ticker symbol “OIG”.
RBC Capital Markets, UBS Investment Bank, and Raymond James will act as lead book-running managers. Goldman Sachs, Deutsche Bank Securities, Citizens Capital Markets, and Texas Capital Securities will act as book-running managers for the proposed offering.
Upon completion of the offering, the firm will have two classes of authorised common stock. The rights of both are identical, except in voting, conversion, and transfer rights. Immediately post-closing, founder and chief executive officer Kenneth Gregg will be the only holder of Class B common stock, giving him significant voting power over matters submitted to shareholders for approval.
The filing set out the rationale for the listing.
“The principal purposes of this offering are to increase our capitalization and financial flexibility and to create a public market for our Class A common stock. We intend to use the net proceeds from this offering as capital to grow our business and for other general corporate purposes. We periodically evaluate strategic opportunities; however, we have no current commitments for any material acquisitions or investments at this time,” reads the filing.
