Neptune Insurance Holdings Inc. (NP) Stock Price & How to Invest

Neptune Insurance Holdings (NYSE: NP) is a St. Petersburg, Florida insurtech whose main subsidiary, Neptune Flood, is the largest private flood insurance seller in the United States. It operates as a managing general agent, meaning it uses its proprietary AI platform, Triton, to quote, underwrite, and issue residential and commercial flood policies on behalf of a panel of insurance-carrier and reinsurance partners, then earns commissions and fees rather than holding most of the underlying catastrophe risk on its own balance sheet. Triton runs without traditional human underwriters, processes roughly 20,000 quotes on a typical day, and had generated more than 29.7 million lifetime quotes and bound over 1.1 million policies as of mid-2025, with a lifetime written loss ratio around 24.7%. Neptune also offers excess flood coverage and has begun beta-testing parametric and indemnity earthquake products.

The company was led to a NYSE listing on October 1, 2025 by chairman and chief executive Trevor Burgess, whose IPO raised roughly $368 million and saw shares climb about 24% on the first day. Burgess, who previously founded C1 Bank and took it public before a $402 million sale, holds roughly 82% of the voting power, which makes Neptune effectively a founder-controlled company. Its addressable market is large: the federal National Flood Insurance Program still writes the majority of US flood policies while an estimated 20 million American properties carry no flood coverage at all, and Neptune's own analysis suggests a majority of new NFIP policyholders would pay less in the private market, often for broader coverage.

The central risks are catastrophe and reinsurance related. Neptune concentrates in a single, weather-exposed line, so a severe flood season or a string of major storms could spike losses and, more importantly for an agency model, raise the cost or reduce the availability of the reinsurance capacity it depends on. Its economics are also tied to the political fate of the NFIP, whose periodic reauthorization and reform can shift the competitive landscape in either direction. As a recently public, founder-controlled company (CEO Trevor Burgess holds around 82% of voting power), minority shareholders have limited say, and the roughly 120x P/E leaves little room for disappointment if growth or margins slow. Widening loss ratios, higher acquisition costs from new competitors, and regulatory changes across states are additional pressures.

A simple financial snapshot. These are approximations and refresh quarterly; for current figures see Neptune Insurance Holdings Inc.'s investor relations page or your broker.

• Revenue (Q1 2026 quarterly): ~$37.8 million, up 29% year over year
• Adjusted EBITDA (Q1 2026): ~$21.6 million (~57% margin), up 26%
• Net income (Q1 2026): ~$7.3 million (~$13.4 million adjusted)

• Market cap: ~$3.8 billion (stock ~$27 per share)

Figures are approximate and tied to the asOf date; verify live numbers before acting. NP trades at a steep growth multiple, roughly 120x trailing earnings, which reflects investor expectations for continued premium-in-force growth and high agency margins rather than a mature insurer's valuation. The 52-week range (about $14.78 to $33.23) shows how much the stock has moved since its October 2025 IPO, so the numbers matter most as a measure of how much future expansion is already priced in.

There are three common ways to get NP exposure. Buy shares (or fractional shares) directly at any major broker. Hold an ETF that includes it, which spreads the position across many companies. Or build it into a focused thematic basket, so NP sits alongside other stocks that express the same thesis.

Walnut takes the basket route. Describe a thesis where NP fits (for example “AI infrastructure” or “dividend-growth large-caps”) and the AI proposes 5 to 6 constituents with target weights. You review the plan and fund it through your own broker when you're ready.
