Neptune Flood Targets $2.8 Billion Valuation in IPO with T. Rowe Price Backing

Neptune Insurance Holdings, operating as Neptune Flood, is poised for a significant market debut with an initial public offering that could value the St. Petersburg-based flood insurer at approximately $2.76 billion. The company expects to price its shares between $18 and $20 per share, with investment giants T. Rowe Price Investment Management and Alliance Bernstein each committing to purchase $75 million worth of Class A shares as cornerstone investors in the IPO.

The involvement of T. Rowe Price, which manages $1.7 trillion in assets and has made over 300 portfolio investments, provides substantial validation for Neptune Flood's business model and growth prospects. This investment follows T. Rowe Price's recent strategic moves, including a partnership with Goldman Sachs where Goldman will invest up to $1 billion in T. Rowe Price's stock, aiming to own up to 3.5% of the fund giant. The collaboration seeks to combine T. Rowe Price's investing expertise with Goldman's innovation in private and public markets to create new opportunities for retirement savings and wealth creation.

In the Neptune IPO, only existing shareholders are selling shares, totaling 18.4 million shares for gross proceeds of up to $368 million. Selling stockholders include Neptune co-founder Jim Albert, New York-based private equity firm Bregal Sagemount, and FTV Capital. CEO Trevor Burgess, who previously led Florida's C1 Bank, will maintain significant control as the major shareholder with voting power over 80% following the public offering.

Founded in 2016, Neptune Flood has experienced remarkable growth under Burgess's leadership since he assumed control in early 2019 after acquiring a controlling stake in 2018. The company has raised a modest $12.6 million over three funding rounds, with its largest being a $10 million Series A round in March 2023. Strategic acquisitions have been key to Neptune's expansion, including the 2021 purchase of Jumpstart, a parametric insurance company, and the 2024 acquisition of Charles River Data to enhance in-house data science, AI and machine learning capabilities.

Today, Neptune stands as the largest private flood insurance provider in the United States, operating in all 50 states and the District of Columbia with AM Best-rated insurance companies as partners. The company has insured property valued in excess of $100 billion, writing policies for more than 235,000 customers. Financial performance has been strong, with Neptune reporting $119.3 million in revenue and $34.6 million in net income for 2024. The company has secured $400 million in premium capacity for 2025, up from $300 million in 2024, supported by more than 30 global reinsurance and specialty market partners. Neptune has applied to list on the NYSE under the symbol "NP," marking a significant milestone for the specialized insurance provider.
