Insights

Equity analyst – P&C insurance

Record 2025 profitability, strong ROE and disciplined 2026 guidance signal a structurally improved franchise.

Kingstone delivered a step-change in performance in 2025. Net premiums earned grew to $187.1 million while the net combined ratio improved to 75.0%, yielding net income of $40.8 million and diluted EPS of $2.88. Annualized return on equity of 43.0% indicates robust capital efficiency.

Underlying drivers include the Select platform, now 57% of policies in force, and a reduced net expense ratio of 30.0%, down from 41% in 2021, supporting better margins. The catastrophe loss ratio of 1.2% in 2025 was benign, but management stresses that improvements are structural via risk selection and cost control.

For 2026, guidance assumes direct premiums written growth of 16%–20%, an underlying combined ratio of 74%–76%, diluted EPS of $2.20–$2.90, and ROE of 24%–30%, with a higher cat load of 7%–10%. An illustrative EPS of about $3.53 at the 2025 cat ratio shows sensitivity; actual results will depend on catastrophe experience and execution against these targets.

Credit and balance sheet specialist

Capital strengthened materially with higher equity, lower debt and a sizable reinsurance tower.

Total stockholders’ equity increased to $122.7 million as of December 31, 2025, up from $66.7 million a year earlier, driven by retained earnings and improved other comprehensive income. Diluted book value per share rose to $8.28, with book value excluding AOCI at $8.69.

Debt declined to $4.4 million from $11.2 million, and the company reports no holding company debt. Investments grew to $309.7 million, while the catastrophe reinsurance program provides a $440 million tower with a first-event retention of about $5 million pre-tax, limiting earnings volatility from large events.

Management highlights insurance subsidiary surplus of $99 million and reinstated a quarterly dividend of $0.05 per share in 2025. Future outcomes will depend on catastrophe activity, reserve development and continued underwriting discipline under the 2026 guidance framework.

Management Commentary

Meryl Golden, President and Chief Executive Officer of Kingstone, stated, "We delivered record results for the fourth quarter and the full year, confirming the preliminary results we reported in February and marking our ninth consecutive quarter of profitability. From year-end 2023 to year-end 2025, we have grown direct premiums written by 39% while improving our combined ratio by 30 points. These results are structural, not simply weather-driven, and they validate the transformation we have executed.

Our competitive advantages are clear. Select, now 57% of policies in force compared to 45% one year ago, continues to drive lower claim frequency through improved risk selection. Our operating efficiency, with a net expense ratio that has improved from 41% in 2021 to 30% in 2025, provides margin durability. Net earned premium growth of 46% for the full year, combined with net investment income growth of 44%, demonstrates the breadth of our earnings power. And our conservative financial position, with no debt and robust reinsurance, means that a major catastrophe event is an income statement impact, not an existential risk.

We are now entering our next chapter of profitable growth. We have set a 2029 goal of $500 million in direct premiums written through continued growth in New York along with measured expansion into new markets, starting with California in Q2, supported by an infrastructure that scales with minimal incremental investment. We are updating our 2026 guidance today, which reflects continued direct premiums written growth of 16% to 20% and an underlying combined ratio1 of 74% to 76%. We will continue to execute with discipline, advance our measured expansion roadmap and allocate capital prudently to deliver long-term value to our shareholders."

Fiscal Year 2026 Outlook

(see “Disclaimer and Forward-Looking Statements” below)

The Company is providing an updated growth and profitability outlook for fiscal year 2026. The guidance ranges below reflect management’s current expectations based on information available as of March 5, 2026 and are subject to the risks and uncertainties described in “Disclaimer and Forward-Looking Statements” below.

Guidance Metrics			2026 Estimate			2025 Actual
Direct premiums written1,5 growth			16% to 20%			14.8%
Net combined ratio			81% to 86%			75.0%
Underlying combined ratio1,2 (excluding catastrophe losses and prior-year reserve development)			74% to 76%			74.4%
Prior-year reserve development			—%			(0.6)%
Catastrophe loss ratio3			7% to 10%			1.2%
Net income per share – diluted			$2.20 to $2.90			$2.88
Return on equity			24% to 30%			43.0%
Illustrative: Net income per share - diluted at 2025 Actual catastrophe loss ratio (1.2%)4			~$3.53

¹Refer to “Definitions and Non-GAAP Measures” for definitions and 2025 reconciliations.

²The Underlying Combined Ratio is a non-GAAP measure. It is computed as the sum of the underlying loss ratio (which is a non-GAAP measure) and the net underwriting expense ratio. The underlying loss ratio excludes catastrophe losses and prior-year reserve development from the GAAP net loss ratio. The most directly comparable GAAP measure is the net combined ratio. Refer to the section entitled “Definitions and Non-GAAP Measures” included in this press release for definitions and reconciliations of non-GAAP financial measures. A reconciliation of the 2026 estimate of Underlying Combined Ratio to the GAAP net combined ratio is not provided because the Company is unable to predict catastrophe losses and prior-year reserve development with reasonable certainty without unreasonable efforts. These items could materially impact the GAAP measure.

³ The catastrophe loss ratio estimate for 2026 of 7% to 10% is at or above the Company’s six-year historical average of 7.1% (2019–2024) and gives effect to the elevated winter storm activity experienced in early 2026. Catastrophe losses are reported net of reinsurance recoveries and include loss adjustment expenses. The Company defines catastrophe events consistent with PCS industry designations.

⁴ Illustrative sensitivity only; not forward-looking guidance. Represents guidance-midpoint net income per share-diluted recalculated at FY2025 actual catastrophe loss ratio of 1.2%, assuming that all other guidance assumptions remain constant. This figure is provided for modeling context only.

5Guidance for the most comparable GAAP measure, net premiums earned, is not provided because net premiums earned is an output of multiple variables including direct written premium growth, quota share cession rates, and premium earning patterns, several of which are not within the Company’s direct control, therefore the Company is unable to predict such variables with reasonable certainty without unreasonable efforts.

Catastrophe Sensitivity

For purposes of the 2026 guidance, it is assumed that each 1 point of catastrophe loss ratio will result in ~$2.5 million pre-tax losses, or ~$0.13 per diluted share after tax, as indicated below:

CAT Sensitivity Metric (Per 1.0 pt change)			2026E
Pre-tax underwriting impact			~$2.5 million
After-tax underwriting impact per share (at assumed effective tax rate)			~$0.13 per share

Key Modeling Assumptions

The following reflects certain key modeling assumptions with respect to the full year 2026 guidance:

Assumption			2026E
Illustrative net premiums earned*			~$252 million
Assumed effective tax rate			21%
Weighted average diluted shares outstanding			14.8 million

* For modeling purposes only. The illustrative net premiums earned figure is a baseline assumption used solely for the catastrophe sensitivity calculations above. It is not forward-looking guidance on net premiums earned and should not be interpreted as such. Net premiums earned is an output of multiple variables including direct written premium growth, quota share cession rates, and premium earning patterns, several of which are not within the Company’s direct control.

Definitions and Non-GAAP Measures

Direct premiums written represent the total premiums charged on policies issued by the Company during the respective fiscal period.

Net premiums written are direct premiums written less premiums ceded to reinsurers. Net premiums earned, the GAAP measure most comparable to direct premiums written and net premiums written, are net premiums written that are pro-rata earned during the fiscal period presented. All of the Company’s policies are written for a twelve-month period. Management uses direct premiums written and net premiums written, along with other measures, to gauge the Company’s performance and evaluate results. Direct premiums written and net premiums written are provided as supplemental information, not as a substitute for net premiums earned, and do not reflect the Company’s net premiums earned.

Adjusted EBITDA is net income (loss) exclusive of interest expense, income tax expense (benefit), depreciation and amortization, loss on extinguishment of debt, net gains (losses) on investments, gain on sale of real estate, and stock-based compensation. Net income (loss) is the GAAP measure most closely comparable to adjusted EBITDA.

Management uses adjusted EBITDA along with other measures to gauge the Company’s performance and evaluate results, which can be skewed when including interest expense, income tax expense (benefit), depreciation and amortization, loss on extinguishment of debt, net gains (losses) on investments, gain on sale of real estate, and stock-based compensation, and may vary significantly between periods. Adjusted EBITDA is provided as supplemental information, not as a substitute for net income and does not reflect the Company’s overall profitability.

Operating net income and basic operating net income per share is net income and basic income per share exclusive of net gains (losses) on investments and gain on sale of real estate, net of tax. Net income and basic net income per share are the GAAP measures most closely comparable to operating net income and basic operating net income per share.

Management uses operating net income and basic operating net income per share along with other measures to gauge the Company’s performance and evaluate results, which can be skewed when including net gains (losses) on investments and gain on sale of real estate and may vary significantly between periods. Operating net income and basic operating net income per share are provided as supplemental information, not as a substitute for net income and basic net income per share and do not reflect the Company’s overall profitability.

Operating net income and diluted operating net income per share is net income and diluted income per share exclusive of net gains (losses) on investments and gain on sale of real estate, net of tax. Net income and diluted net income per share are the GAAP measures most closely comparable to operating net income and diluted operating net income (loss) per share.

Management uses operating net income and diluted operating net income per share along with other measures to gauge the Company’s performance and evaluate results, which can be skewed when including net gains (losses) on investments and gain on sale of real estate and may vary significantly between periods. Operating net income and diluted operating net income per share are provided as supplemental information, not as a substitute for net income and diluted net income per share, and do not reflect the Company’s overall profitability.

Operating return on equity is operating income divided by average equity. Return on equity is the GAAP measure most closely comparable to operating return on equity.

Management uses operating return on equity, along with other measures, to gauge the Company’s performance and evaluate results, which can be skewed when including net gains (losses) on investments and gain on sale of real estate, which may vary significantly between periods. Operating return on equity is provided as supplemental information, is not a substitute for return on equity and does not reflect the Company’s overall return on average common equity.

Underlying loss ratio is a non-GAAP ratio, which is computed as the GAAP net loss ratio excluding the effect of prior year loss reserve development and catastrophe losses.

Management believes that this ratio is useful to investors, and it is used by management to reveal the trends in the Company’s business that may be obscured by prior year loss reserve development and catastrophe losses. Catastrophe losses cause the Company’s loss ratios to vary significantly between periods as a result of their incidence of occurrence and magnitude and can have a significant impact on the net loss ratio. Management believes that this measure is useful for investors to evaluate this component separately when reviewing the Company’s underwriting performance. The most directly comparable GAAP measure is the net loss ratio. The underlying loss ratio should not be considered a substitute for the net loss ratio and does not reflect the Company’s net loss ratio.

Net loss ratio excluding the effect of catastrophes is a non-GAAP ratio, which is computed as the difference between GAAP net loss ratio and the effect of catastrophes on the net loss ratio.

Management believes that this ratio is useful to investors, and it is used by management to reveal the trends in the Company’s business that may be obscured by catastrophe losses. Catastrophe losses cause the Company’s net loss ratios to vary significantly between periods as a result of their incidence of occurrence and magnitude and can have a significant impact on the net loss ratio. Management believes that this measure is useful for investors to evaluate this component separately when reviewing the Company’s underwriting performance. The most directly comparable GAAP measure is the net loss ratio. The net loss ratio excluding the effect of catastrophes should not be considered a substitute for the net loss ratio and does not reflect the Company’s net loss ratio.

Underlying combined ratio is a non-GAAP measure, which is computed as the sum of the underlying loss ratio and the net underwriting expense ratio.

Management believes that this ratio is useful to investors, and it is used by management to reveal the trends in the Company’s business that may be obscured by prior year loss reserve development and catastrophe losses. Catastrophe losses cause the Company’s loss ratios to vary significantly between periods as a result of their incidence of occurrence and magnitude and can have a significant impact on the net combined ratio. Management believes that this measure is useful for investors to evaluate this component separately when reviewing the Company’s underwriting performance. The most directly comparable GAAP measure is the net combined ratio. The underlying combined ratio should not be considered a substitute for the net combined ratio and does not reflect the Company’s net combined ratio.

See section entitled “Definitions and Non-GAAP Measures” and the tables included in our press release dated March 5, 2026 for reconciliations of these non-GAAP financial measures to the most directly comparable GAAP measures and the reasons management uses each measure. ² The Underlying Combined Ratio is a non-GAAP measure. It is computed as the sum of the underlying loss ratio (which is a non-GAAP measure) and the net underwriting expense ratio. The underlying loss ratio excludes catastrophe losses and prior-year reserve development from the GAAP net loss ratio. The most directly comparable GAAP measure is the net combined ratio. Refer to the section entitled “Definitions and Non-GAAP Measures” included in our press release dated March 5, 2026 for definitions and reconciliations of non-GAAP financial measures. A reconciliation of the 2026 estimate of Underlying Combined Ratio to the GAAP net combined ratio is not provided because the Company is unable to predict catastrophe losses and prior-year reserve development with reasonable certainty without unreasonable efforts. These items could materially impact the GAAP measure. ³ The catastrophe loss ratio estimate for 2026 of 7% to 10% is at or above the Company’s six-year historical average of 7.1% (2019–2024) and gives effect to the elevated winter storm activity experienced in early 2026. Catastrophe losses are reported net of reinsurance recoveries and include loss adjustment expenses. The Company defines catastrophe events consistent with PCS industry designations. ⁴ Illustrative sensitivity only; not forward-looking guidance. Represents guidance-midpoint. 5 Guidance for the most comparable GAAP measure, net premiums earned, is not provided because net premiums earned is an output of multiple variables including direct written premium growth, quota share cession rates, and premium earning patterns, several of which are not within the Company’s direct control, therefore the Company is unable to predict such variables with reasonable certainty without unreasonable efforts. * For modeling purposes only. The illustrative net premiums earned figure is a baseline assumption used solely for the catastrophe sensitivity calculations above. It is not forward-looking guidance on net premiums earned and should not be interpreted as such. Net premiums earned is an output of multiple variables including direct written premium growth, quota share cession rates, and premium earning patterns, several of which are not within the Company’s direct control. 14
