Neptune is a data driven managing general agent that focuses on flood and related natural disaster risks. The company was created to address inefficiencies in the traditional flood insurance market and to provide a technology first alternative. Neptune does not retain underwriting risk or handle claims; instead it issues and administers policies on behalf of a panel of insurance and reinsurance partners that supply the capital. Its core product suite consists of primary flood insurance, excess flood insurance, and parametric earthquake insurance. These products are distributed nationwide through a network of independent insurance agents and brokers. Neptune’s operations are built around three pillars: an artificial intelligence underwriting engine named Triton, a policy management system called Poseidon, and a set of deep relationships with capacity providers that back the policies. The underwriting engine processes tens of thousands of quotes each day and relies on proprietary machine learning models that are continuously refined with data from the company’s own operations. This approach enables Neptune to offer instant quotes, bind policies in real time, and maintain a low loss ratio for its partners.

Neptune generates revenue primarily through commission sharing with its capacity providers and policy level fees. Commissions are calculated as a negotiated percentage of the premium on each policy and have increased steadily as partners recognize the firm’s superior underwriting performance. In addition to commissions, the company collects fees from policyholders for policy issuance, endorsements, and ancillary services. The firm’s revenue model is highly recurrent because a large share of policies renew each year, providing visibility into future cash flows. For the fiscal year ended December 31, 2025, Neptune reported $159.6 million in total revenue, driven by a 33.7% year over year increase in organic sales. During the same period, the company generated $37.4 million in net income and $95.0 million in adjusted EBITDA, representing margins of 23.4% and 59.5% respectively. Retention metrics underscore the stability of the business, with eligible policy retention at 86.1% and premium retention at 98.0% for the year ended 2025.

Neptune occupies a leading position among private flood insurers in the United States, where the market is dominated by the federal National Flood Insurance Program. Unlike the NFIP, which relies on subsidized pricing and standardized coverage limits, Neptune leverages proprietary machine learning models to offer risk based pricing, higher coverage limits, and a fully digital quote to issue process. This technological edge has yielded a lifetime written loss ratio of just 24.7% for its capacity partners, far below the NFIP’s historical average and the broader property and casualty industry. The company estimates that as of the end of 2025 it held approximately 8.2% of the U. S. primary residential flood insurance market, indicating substantial room for growth. Neptune’s competitive advantages include its data driven underwriting platform, its diversified panel of more than 40 capacity providers, and its extensive distribution network that reaches tens of thousands of agents. The firm’s ability to quickly adapt its models to new perils and geographies further strengthens its position relative to slower moving incumbents. Overall, Neptune is viewed as a technology leader that can capture market share as the NFIP moves toward risk based pricing and as demand for flood protection expands.

Neptune serves residential and commercial property owners seeking flood protection, with the majority of its premium derived from homeowners. The company’s distribution depends on independent insurance agents and brokers who use the company’s API and agent portal to obtain instant quotes and bind policies. As of the end of 2025, more than 23,000 unique agency codes had bound a policy through Neptune and nearly 100,000 agency codes had run a quote on its platform. These agency partners range from large captive agent forces of national carriers to wholesalers, regional agencies, flood specialists and small independent firms. No single agency accounts for more than 8.7% of the total policyholder base, indicating a well diversified distribution footprint. Geographically, the business is spread across all 50 states and the District of Columbia, with concentrations in Florida, Texas and Louisiana that are lower than those of the NFIP. While the filing does not disclose individual client names, the customer base consists of individuals, families, and businesses that own property exposed to flood risk.
