Material Changes vs. Prior Period

- Expense Increases: Total operating expenses rose 74.2% to $88.6 million. Key drivers included:
- Agent Commissions: Increased 38.9% to $49.1 million, directly correlated with policy volume growth.
- Share-Based Compensation: Surged to $11.4 million from $0.3 million, largely due to the acceleration of vesting upon the IPO.
- IPO Transaction Costs: $8.9 million in one-time costs were incurred in 2025 (none in 2024).
- Debt Restructuring: In November 2025, the company amended its credit agreement, converting term loans into a $260.0 million revolving credit facility. As of year-end, $240.0 million was drawn, leaving $20.0 million available.

Guidance, Outlook, and Risks
Management Commentary & Outlook:
- Technology Advantage: Management emphasizes the "Triton" underwriting engine, which has delivered a lifetime written loss ratio of 24.7% for capacity providers, significantly outperforming the NFIP (National Flood Insurance Program) and industry averages.
- Retention: Policy retention rate was 86.1% and premium retention rate was 98.0% for 2025, indicating strong recurring revenue visibility.
- Market Opportunity: The company anticipates growth driven by the NFIP's "Risk Rating 2.0" pricing model, which is expected to increase premiums for many policyholders, making private alternatives like Neptune more competitive.
- Product Expansion: Neptune launched an excess flood insurance product in 2024 and began beta testing an indemnity earthquake product in California in late 2025.
Key Risks & Contingencies:
- Capacity Provider Relationships: As an MGA, Neptune relies entirely on third-party insurers for risk assumption. Termination or reduction of capacity by these providers would halt operations.
- Regulatory Environment: Changes in NFIP regulations, state insurance laws, or the Biggert-Waters Act could impact the private flood market. The company operates on an Excess and Surplus (E&S) basis, which offers flexibility but requires strict compliance.
- Technology & AI Risks: Reliance on the Triton platform exposes the company to risks of algorithmic errors, data inaccuracies, and cybersecurity threats. Rapid advancements in AI by competitors could also erode competitive advantages.
- Concentration of Control: The CEO holds a controlling interest via Class B stock, limiting the influence of public shareholders on corporate governance.
- Debt Covenants: The company is subject to financial covenants (leverage and interest coverage ratios) under its credit agreement. Failure to comply could result in default.
Investor Verification Checklist
- Capacity Renewals: Verify the renewal rates and terms of the 40 capacity providers to ensure continued underwriting capacity.
- Loss Ratio Performance: Monitor the lifetime written loss ratio (currently 24.7%) to ensure the AI underwriting model continues to outperform the NFIP and industry peers.
- Debt Servicing: Assess the impact of the $240 million revolving debt and associated interest expense ($18.2 million in 2025) on future cash flows and dividend capacity.
- Retention Metrics: Track policy and premium retention rates to validate the recurring revenue model and the effectiveness of the ML-driven renewal optimization.
- Regulatory Changes: Monitor legislative developments regarding the NFIP and the Biggert-Waters Act that could alter the competitive landscape for private flood insurance.
- Share-Based Compensation: Evaluate the sustainability of share-based compensation expenses, which spiked significantly in 2025 due to the IPO.
