HIGHLIGHTS Q4 2025 2025 SUMMARY Profitability Revenue (millions) $ 43.8 $ 159.6 2025 marked a pivotal year for Neptune as we completed our transition to a public company and demonstrated the durability and scalability of our AI-driven operating model. Neptune was built from inception as a technology-first, API-enabled insurance platform. We believe our proprietary flood datasets, machine learning underwriting models, and fully digital transaction infrastructure position us to lead the continued digitization of catastrophe insurance. As artificial intelligence reshapes distribution and underwriting workflows across the industry, we expect Neptune to have a significant structural advantage. Our performance in 2025 reflected the strength of our model. We delivered strong revenue growth while maintaining robust margins, reinforcing our anticipated ability to generate long- term shareholder value. Execution across technology, capacity, and distribution drove record written premium, strong policy and premium retention, and meaningful operating leverage. Our underwriting performance continued to attract additional high-quality capacity partners, expanding and diversifying our panel while improving average commission economics. Importantly, Neptune operates as an asset-light MGA and takes no balance sheet insurance risk. By combining proprietary data, disciplined underwriting, and scalable technology infrastructure, we believe we will continue to grow profitably while maintaining operational flexibility. During periods of market disruption, including the federal government shutdown late in the year, Neptune remained fully operational and scalable. We believe this consistency further strengthened our relationships with agents, homeowners, and capacity providers. As we enter 2026, we do so with: • A growing and diversified capacity panel; • A compounding proprietary data advantage; • Flexible distribution infrastructure; and • A proven, high-margin operating model We believe these foundations create a durable competitive moat and position Neptune to lead in an increasingly AI-enabled insurance landscape.

USE OF CASH In November, we refinanced our outstanding term loans into a $260 million revolving credit facility, with $240 million outstanding at year end 2025. The transition to a revolving credit facility removes mandatory repayments and provides greater flexibility in capital management. Operating cash flow for the twelve months ended December 31, 2025, was $49.8 million, compared to $49.9 million for the prior year. Operating cash flow was reduced as a result of $8.4 million in IPO related expenses that were reimbursed as contributed capital. 4.3 1.9 3.9 1.8 2.5 Q4 Q1 Q2 Q3 Q4 Q1 Q2 Q3 Q4 Q1 Q2 Q3 Q4 Q1 Q2 Q3 Q4 1 2 3 4 5 2021 2022 2023 2024 2025 Total Net Leverage Ratio 9

Operations

TECHNOLOGY Technology continued to drive efficiency and scalability across our business in 2025. During the year, we released more than 78 production versions of the Triton platform, including a full rewrite of our core pricing and risk selection algorithms. The Triton system scaled seamlessly throughout the year, processing approximately 6 million quotes and supporting 34.1% written premium growth to $367 million. Machine learning models deployed across underwriting, sales, and retention continued to deliver measurable performance improvements. In 2025, these models contributed to a 180-basis point increase in policy retention to 86.1% and a 100-basis point increase in revenue retention to 91.7%. Technology remains a core area of investment as we enter 2026 with continued focus on automation, model performance, and platform scalability. 162 203 256 468 546 Triton Versions 2021 2022 2023 2024 2025 0 100 200 300 400 500 600 84% 89% 90% 91% 92% Revenue Retention 2021 2022 2023 2024 2025 0% 20% 40% 60% 80% 100% M illi on s $89 $143 $202 $274 $367 Written Premium 2021 2022 2023 2024 2025 $— $100 $200 $300 $400 11

CAPACITY The number of capacity providers supporting the Neptune program increased 74% during 2025. As of year-end 2025, 40 capacity providers supported 8 programs across 9 products, providing more than $122 billion of coverage to approximately 280,200 property owners nationwide. Neptune does not take insurance risk, making value creation for our capacity partners a core tenet of our business. We believe technology, underwriting performance, and operational scale continue to support long-term alignment with our capacity panel. Average commission income as a percent of written premium increased by 35 basis points from year ended December 31, 2024, to year ended December 31, 2025, reflecting sustained value delivered to capacity providers over time. During the year, we added the Palomar capacity program and signed a new program with Somers Re in the fourth quarter, which went live in January 2026.

DISTRIBUTION 2025 marked a record sales year, with both the third and fourth quarters setting new quarterly sales records. Growth was driven by continued strength in primary residential flood and the expansion of distribution partnerships. New business generated through the Palomar relationship further accelerated fourth-quarter sales. Policies associated with this program are expected to roll onto the Neptune book between October 1, 2025, and September 30, 2026. Market conditions during the fourth quarter contributed to higher agent engagement, driving growth in quotes and binds. We also launched a new individual user-based agent login system in the fourth quarter, replacing the prior agency-based login model. Within 30 days of launch, more than 30,000 agents created individual accounts, enabling more personalized engagement and future enhancements to the agent experience.

(2)This represents the tax impact using the applicable effective tax rate for each respective period presented, excluding items that are non-deductible/non-taxable or subject to a specific tax treatment. (3)Assumes the conversion of all shares of Redeemable Convertible Preferred Stock into an equivalent number of shares of common stock. (4)For comparability purposes, this calculation reflects net income that would be distributable to holders of common stock assuming all redeemable preferred shares had been converted and therefore no longer impacted the numerator. Accordingly, accretion adjustments and dividends or other allocations attributable to redeemable preferred stock have been added back to net income, as applicable for each period presented. These adjustments were divided by the weighted-average shares outstanding for each respective period to calculate adjusted earnings (basic and diluted) per share. (5)Other adjustments to earnings (loss) represent loss on extinguishment of debt, amortization expense, share-based compensation, corporate transaction related expenses, and one-time expenses. (6)Represents the impact of 3,531,938 stock options and 676,659 RSUs that were considered anti-dilutive in the GAAP diluted weighted-average common stock outstanding calculation but are included for purposes of Adjusted diluted earnings per share, for the year ended December 31, 2025.

Non-GAAP Financial Measures and Key Performance Indicators To supplement our condensed consolidated financial statements, which are prepared and presented in accordance with generally accepted accounting principles in the United States (GAAP), we use the following non-GAAP financial measures: Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Net Income, and Adjusted Diluted Earnings per Share. The presentation of these financial measures is not intended to be considered in isolation or as a substitute for, or superior to, financial information prepared and presented in accordance with GAAP. Investors are cautioned that there are material limitations associated with the use of non-GAAP financial measures as an analytical tool. In addition, these measures may be different from non-GAAP financial measures used by other companies, limiting their usefulness for comparison purposes. We compensate for these limitations by providing specific information regarding the GAAP amounts excluded from these non-GAAP financial measures. We believe these non-GAAP financial measures provide investors with useful supplemental information about the financial performance of our business, enable comparison of financial results between periods where certain items may vary independent of business performance, and allow for greater transparency with respect to key metrics used by management in operating our business. See “Reconciliation of Non-GAAP Financial Measures” for a reconciliation of non-GAAP measures to the most directly comparable GAAP measures. 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. Additionally, we discuss 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. 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 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, for the trailing four quarters divided by the average number of our employees for the trailing four quarters. We 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 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 monitor the acceptance of renewal offers as an early indicator of price elasticity. Revenue Retention Rate is defined as the percentage of revenue recognized on policies in a given period that is recognized under the renewal terms of those same policies in the subsequent period. We monitor this metric as a comprehensive indicator of renewal performance and the long-term stability of our revenue base, as it reflects the combined effect of policy retention, premium changes, and policy fee income. 26
