Neptune Insurance posts revenue jump as IPO costs pinch profits
For the quarter ended September 30 2025, Neptune Insurance Holdings Inc. (NYSE: NP) achieved $44.4 million in revenue, up 31.2 % year-over-year, yet saw net income fall to $11.5 million as IPO-related expenses weighed on results.

Neptune Insurance Holdings entered the fall with steady momentum. The St. Petersburg company, which went public earlier this year, released its third-quarter results Nov. 12 and showed that demand for its flood insurance products continues to rise. Revenue reached $44.4 million for the quarter that ended Sept. 30, a 31 percent increase from the same period last year.
The growth was driven by a larger base of customers and a higher volume of written premiums. Neptune reported $101.6 million in written premiums during the quarter, up from $77.7 million a year earlier. The numbers reflect the company’s position in a flood insurance market that has become more turbulent and more competitive as storms intensify and homeowners search for alternatives to the federal program.
Despite the jump in revenue, net income edged down slightly. Neptune reported $11.5 million in profit for the quarter, a 4.8 percent decline. The company pointed to about $5 million in expenses tied to its initial public offering. Those costs were expected, but they created a noticeable gap when compared with last year’s profit levels.
Neptune has built its business on a model that avoids taking direct insurance risk. It partners with a group of reinsurers that back the policies it sells. That structure allows the company to scale quickly without carrying the potential losses from major storms on its own balance sheet. It also means the company’s financial results depend heavily on maintaining strong relationships with those global insurance partners.
During the quarter Neptune expanded those relationships. By the end of September the company worked with 33 capacity providers across six programs. A new program launched in October added six more partners and brought the total to 39 across seven programs. The company says this broad base helps keep pricing stable and supports its ability to grow in different regions.
Technology continues to be a central piece of the company’s strategy. Neptune reported that it has rewritten its Triton underwriting system and rolled out a machine-learning model designed to help convert more quotes into active policies. The company promotes its technology as a way to move faster than traditional insurers and streamline the application process for homeowners and agents.
Customer retention remained high through the first nine months of the year. The company said 86.2 percent of policyholders renewed their coverage and premium retention reached 98.7 percent. Those numbers help show how existing customers contribute to the company’s growth, even as it tries to reach new markets.
Neptune ended the quarter with $264 million in total debt. It used $30 million in cash to pay down part of that balance during the summer, then refinanced into a $260 million revolving credit facility on Nov. 10. The company’s leverage remains just under three times its trailing-12-month earnings, a level it described as manageable.
Looking ahead, Neptune expects full-year 2026 revenue to land between $186 million and $189 million. It projects an Adjusted EBITDA margin of 60 to 61 percent, a signal that the company plans to keep its asset-light model intact while continuing to invest in technology.
For a company built in St. Petersburg that now trades on the New York Stock Exchange, the quarter showed both sides of its current stage. Growth remains strong and the customer base is expanding, yet the lingering costs of going public have tempered the bottom line.
