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.
Sectors:Financial Services · TechnologySector rationaleNeptune operates as a managing general agent (MGA) providing flood and earthquake insurance products, generating revenue through commission sharing and policy fees, which falls under the Insurance Brokers/Specialty Finance categories of Financial Services. A secondary sector of Technology is justified because the company's core value proposition and operational pillars are built on proprietary AI underwriting engines (Triton) and policy management systems (Poseidon) sold as a technology-first alternative to traditional insurance.Industries:Insurance BrokersFinancial ServicesPrimaryNeptune operates as a managing general agent (MGA) that issues and administers policies on behalf of insurance and reinsurance partners without retaining underwriting risk. It earns revenue through commission sharing with capacity providers and fees from policyholders, acting as an intermediary that distributes products through a network of independent agents and brokers.InsurtechTechnologySecondaryThe company's core differentiator is its technology-first approach, specifically its AI underwriting engine 'Triton' and policy management system 'Poseidon'.

Investment Thesis
▲ Bull case
Neptune’s AI driven efficiency and proprietary data base create a structural margin floor that management views as a starting point not a ceiling. Revenue per employee reached $2 point eight million and adjusted EBITDA per employee reached $1 point seven million on a trailing 12 month basis both record levels showing the platform can scale revenue without proportional headcount growth. As AI tools such as Atlas+ and Proteus automate distribution and underwriting workflows the company expects operating leverage to improve further pushing adjusted EBITDA margins above the current 60% to 61% range. This margin expansion would directly increase free cash flow and support the recently announced share repurchase program while reinforcing the durability of the competitive moat.
Atlas+ is positioned to transform the agent experience by turning every insurance agent into a super agent capable of generating sales materials answering coverage questions and interacting directly with quotes in real time. Early beta feedback has been extremely strong with examples of policies being sold as a direct result of these interactions indicating the tool can increase conversion rates and deepen agent engagement. With over 45 000 individual agents signed up for direct access and nearly 11 000 already binding new business policies the rollout creates a scalable channel to accelerate new business growth and improve agent stickiness. As the tool expands beyond its initial chat interface it is expected to become a core component of the sales workflow driving higher policy volumes and stronger retention.
Proteus an internally developed AI software developer has already demonstrated its ability to accelerate engineering output by handling over 30% of engineering tickets in March alone effectively nearly doubling the amount of work the team ships. This acceleration allows Neptune’s engineers to focus on high value system design and new capability creation rather than routine execution tasks. The resulting speed advantage enables rapid rollout of product enhancements such as the ChatGPT interface and faster response to market opportunities like the earthquake beta test. Over time Proteus creates a self reinforcing cycle where faster development leads to more data which further improves AI models and widens the technology gap versus competitors.
The capacity panel expanded to 42 reinsurers after a program renewal that increased the size of the treaty and added two new partners signalling strong confidence from the reinsurance community in Neptune’s underwriting performance. This broad and deep capacity base provides the scalability needed to support premium in force growth toward the $400 million threshold and beyond without concentrating risk with a single carrier. As the platform writes more policies the data advantage improves underwriting precision which in turn makes the capacity partners more willing to increase limits and improve terms. The expanded capacity therefore acts as a catalyst for both top line growth and margin stability by reducing reliance on any one source of risk capital.

The success of Atlas+ hinges on changing long standing agent behavior and while early feedback is positive the tool remains in a beta phase with limited scale deployment. There is no guarantee that agents will consistently use the AI assistant to generate sales materials or explain coverage nuances which means the anticipated lift in conversion rates and policy bindings may not materialize. If adoption stalls the expected acceleration in new business growth could be delayed leaving the company dependent on organic agent network expansion alone. This behavioural risk represents a key uncertainty that the market may be underestimating when pricing the stock.
Regulatory developments around FEMA and the NFIP could reshape the flood insurance market in ways that management has acknowledged they have no visibility into. A potential citizen style depopulation or changes to the public program could either reduce demand for private flood insurance or increase competition from a revitalized NFIP offering. Because Neptune’s growth strategy relies on capturing policies from the large uninsured pool and from NFIP holders who would save by switching any shift in government policy could directly impact the addressable market and the company’s growth trajectory. This regulatory uncertainty is a headwind that is not fully reflected in current guidance.
Neptune’s expansion is tightly coupled to housing market turnover because the majority of growth opportunities come from policy switches that occur when homes are bought sold or refinanced. The management team highlighted the ongoing slow real estate market as a headwind noting that without turnover there is no mechanism to shift NFIP policies to the private market. A prolonged downturn in housing transactions would keep the tailwind dormant constraining new business growth despite strong agent tools and advanced technology. The company’s reliance on an external macro variable introduces cyclical risk that could suppress revenue growth even if internal execution remains strong.
Capital allocation choices such as the $100 million share repurchase program and the ongoing RSU net tax settlements may divert free cash flow from reinvestment in growth initiatives. While debt reduction improves the balance sheet the use of cash for buybacks limits the amount available to fund further AI product development capacity expansion or additional distribution incentives. If the buyback program consumes a large portion of the generated free cash flow the compounding effect described by management could be slowed potentially affecting long term margin expansion and market share gains. This trade off between returning capital and reinvesting for growth represents a risk that investors should consider.
