Exhibit 99.1

Neptune Insurance Holdings Inc. Reports Third Quarter 2025 Results

November 12, 2025

ST. PETERSBURG, Fla., Nov. 12, 2025 -- Neptune Insurance Holdings Inc. (“Neptune” or the “Company”) (NYSE: NP), the parent company of Neptune Flood Incorporated, today reported revenue of $44.4 million for the third quarter of 2025, up 31.2% from the third quarter of 2024. The Company reported net income of $11.5 million and Adjusted EBITDA of $26.7 million. Adjusted EBITDA increased 28.6% compared to the same period in 2024.

Third Quarter 2025 Highlights

Trevor Burgess, Chairman and Chief Executive Officer, commented, “The excellent results delivered in Q3 showcase the scalability and efficiency of our model. Expanding distribution, record new business policy sales, strong renewal dynamics, and continued technology leverage helped produce 31% revenue growth, a 26% net income margin, and a 60% Adjusted EBITDA margin. Operating as a managing general agent (MGA) that takes no balance sheet insurance risk, a model we believe is unique to the public markets, allows us to deliver these margins and provide a financial profile that is efficient, asset light, and profitable.”

“We’re most proud of the exceptional customer experience we provide to agents and consumers nationwide, and the consistent profitability we have historically provided to our capacity providers,” said Mr. Burgess. “We believe this is only possible because we are a technology company operating in the insurance space, not an insurance company attempting to utilize technology.”

Mr. Burgess continued, “Following quarter end, we refinanced our debt into a $260 million revolving facility, which lowers our rate, removes required amortization, and provides greater flexibility to manage capital efficiently.”

Financial Performance

Revenues increased 31.2% to $44.4 million compared to $33.8 million in the third quarter of 2024, while written premiums increased 30.7% to $101.6 million compared to $77.7 million in the third quarter of 2024.

Net income decreased 4.8% to $11.5 million compared to $12.1 million in the third quarter of 2024, while Adjusted EBITDA increased 28.6% to $26.7 million compared to $20.8 million in the third quarter of 2024. Net income margin was 25.9% and Adjusted EBITDA margin was 60.2% for the third quarter of 2025. On a trailing-twelve-month basis, net income was $44.7 million and Adjusted EBITDA was $88.4 million. The largest adjustment to net income in the third quarter of 2025 was $5.0 million of costs related to the Company’s Initial Public Offering (IPO). In total, the Company incurred $8.4 million of such costs in the nine months ended September 30, 2025, which were reimbursed by the selling shareholders in the IPO upon closing of the offering during the fourth quarter.

Technology

Technology continues to drive operational leverage as demonstrated in revenue per employee of $2.5 million and $1.5 million of Adjusted EBITDA per employee for the trailing-twelve-months ended September 30, 2025, up 28.9% and 30.3%, respectively, from the prior corresponding period. Technology projects deployed in the third quarter include a full rewrite to upgrade the Company’s proprietary Triton® underwriting system and a new machine learning model focused on optimizing new business quote conversion.

Capacity Relationships

At quarter end, Neptune worked with 33 capacity providers across six programs. On October 1, 2025, the Company commenced a new program, adding six new reinsurers and bringing the panel to 39 capacity providers across seven programs.

Distribution

The Company achieved record new business sales in the third quarter, with federally required purchases accounting for under 20% of new business sales, a metric we believe shows the continued expansion of the flood insurance market. The Company also saw a record number of new agency codes binding policies during the third quarter, a metric we believe shows growth in both the breadth and depth of our distribution relationships.

Retention across the portfolio remained strong for the nine months ended September 30, 2025, with a Policy Retention Rate of 86.2% and a Premium Retention Rate of 98.7%, up 2.8 and 1.9 percentage points, respectively, compared to the same period in 2024.

Capital and Liquidity

Total debt was $264 million at September 30, 2025, reflecting a trailing-twelve-month Total Net Leverage Ratio (as defined in our credit agreement) of just under three times. During the third quarter, the Company utilized $30 million of cash to pay down debt. On November 10, 2025, Neptune refinanced its outstanding term loans into a $260 million revolving credit facility, with $251 million currently outstanding.

Operating cash flow for the nine months ended September 30, 2025, was $38.9 million, compared to $35.3 million for the same period in the prior year.

Full Year 2026 Outlook

For the full year 2026, the Company expects to achieve revenue of $186 million to $189 million and Adjusted EBITDA margin of 60 percent to 61 percent. This guidance constitutes a forward-looking statement and actual results may differ materially.

Non-GAAP and Key Performance Indicators

Neptune discusses certain key performance indicators, described below, which provide useful information about the Company’s business and the operational factors underlying the Company’s financial performance.

See “Reconciliation of Non-GAAP Financial Measures” for a reconciliation of non-GAAP measures to the most directly comparable GAAP measures.

Adjusted EBITDA is a non-GAAP financial measure derived from net income (the most directly comparable GAAP measure) adjusted to exclude interest expense (net of interest income), income taxes, depreciation and amortization, and further adjusted for other non-cash or non-recurring items, including share-based compensation. By removing these expenses, we believe Adjusted EBITDA provides a clearer representation of operating performance.

Adjusted EBITDA Margin is a non-GAAP financial measure derived from Adjusted EBITDA divided by revenue. We believe that Adjusted EBITDA margin is a useful measurement of operating profitability for the same reasons we find Adjusted EBITDA useful and also because it provides a period-to-period comparison of our operating performance.

Adjusted Net Income is a non-GAAP financial measure derived from net income (the most directly comparable GAAP measure), adjusted to exclude loss on extinguishment of debt, amortization expense, share-based compensation, corporate transaction related expenses, and other one-time expenses, and the related tax effect of those adjustments. By removing these expenses, we believe Adjusted net income provides a clearer representation of operating performance.

Adjusted Diluted Earnings per Share is Adjusted Net Income divided by diluted weighted average shares outstanding, assuming the conversion of all outstanding shares of redeemable convertible preferred stock into an equivalent number of shares of common stock, which occurred upon the consummation of our IPO. Similarly, Adjusted basic earnings per share is Adjusted net income divided by basic weighted average shares outstanding, also assuming the conversion of all outstanding redeemable convertible preferred stock into an equivalent number of shares of common stock, which occurred upon the consummation of our IPO. By implementing the conversion of the redeemable convertible preferred stock, we believe Adjusted earnings (basic and diluted) per share provides a clearer representation of operating performance. The most directly comparable GAAP measures are diluted earnings per share and basic earnings per share, respectively.

Written Premium is a key performance indicator defined as the total premium we placed with insurance programs during a reporting period, less “return premiums” refunded to policyholders due to cancellations, endorsement of policies, or otherwise. We believe written premium is an appropriate measure of operating performance because it is the primary driver of our commission revenue.

Revenue per Employee is a key performance indicator defined as revenue for the trailing four quarters, determined in accordance with GAAP, divided by the average number of our employees for the trailing four quarters. We closely monitor this as a metric of scaling growth and believe it to be a leading indicator of sustained profitability and efficiency.

Adjusted EBITDA per Employee is a key performance indicator defined as Adjusted EBITDA, a non-GAAP metric (defined above) for the trailing four quarters divided by the average number of our employees for the trailing four quarters. We closely monitor this as a metric of scaling growth and believe it to be a leading indicator of sustained profitability and efficiency.

Policy Retention Rate is a key performance indicator defined as the percentage of our policyholders who receive renewal offers that accept the offered renewal term. We closely monitor the acceptance of renewal offers as an early indicator of price elasticity.

Premium Retention Rate is a key performance indicator defined as the premium associated with those accepted renewal offers, as a percentage of the total premium from expiring policies for which renewal offers were made. We closely monitor the acceptance of renewal offers as an early indicator of price elasticity. This often tracks significantly higher than policy retention, as price increases mean fewer units would be necessary to maintain the same amount of premium. Higher premium results in higher commission, but large price increases can decrease policy retention and the associated policy fees. Because of this inverse relationship between premium and policy retention, we use data science and ML to inform renewal pricing to optimize for revenue retention.
