Management Commentary

Kevin G. Burke, President and Chief Executive Officer of Donegal Group Inc., stated, “We are encouraged to see a continuation of favorable results in the third quarter, which reflects the benefits of our strategic and tactical efforts over the past several years. While benign weather conditions contributed meaningfully to our quarterly performance, we were also pleased with the overall core loss ratio for the third quarter. We remain confident that our disciplined underwriting and ongoing strategic execution will provide sustained excellent financial performance over time.

“In our commercial lines business segment, we achieved strong renewal price increases coupled with solid retention. The 96.6% statutory combined ratio¹ for this segment reflected our intentional underwriting approach. We have not achieved our target for new business writings through the first nine months of the year, which we attribute to a data-driven refinement of our underwriting appetite. We are proactively working with our agents to increase their submissions of accounts within our desired classes of business. We recently fully deployed the final major commercial lines release of our multi-year systems transformation project, providing enhanced products and service capabilities we expect will enhance our ability to target and win profitable middle market accounts. Coupled with our small business systems and capabilities implemented in recent years, we are now in a solid position to grow our commercial risk portfolio at a measured, intentional pace.

“In our personal lines business segment, we have been maintaining our focus on profitability and controlling new business levels to protect our underwriting margins. We have recently deployed the final major personal lines release of our systems transformation project, which will facilitate the conversion of all remaining legacy policies to our new platform in a phased approach that will be completed in June 2027. We expect modest declines in personal lines premiums through the balance of 2025 and into 2026, as we gradually increase our writing of new business with a goal of maintaining a stable, profitable book of personal lines business.

“We believe that we are now operating from a position of strength and that we are well positioned to navigate the evolving insurance landscape in the years ahead. We will continue to engage with our independent agency partners to identify growth opportunities, further enhance and refine the efficiency of our operations, and execute on our strategic priorities.”

Net Premiums Written

The 5.4% decrease in net premiums written¹ for the third quarter of 2025 compared to the third quarter of 2024, as shown in the table above, represents the net combination of a 3.4% increase in commercial lines net premiums written and a 15.9% decrease in personal lines net premiums written. The $12.6 million decrease in net premiums written for the third quarter of 2025 compared to the third quarter of 2024 included:

Commercial Lines: $4.3 million increase that we attribute primarily to solid retention and a continuation of renewal premium increases in lines other than workers’ compensation, offset partially by lower new business writings.
Personal Lines: $16.9 million decrease that we attribute primarily to planned attrition due to lower new business writings and non-renewal actions, offset partially by a continuation of renewal premium rate increases and solid retention.

Underwriting Performance

We evaluate the performance of our commercial lines and personal lines segments primarily based upon the underwriting results of our insurance subsidiaries as determined under statutory accounting practices. The following table presents comparative details with respect to the GAAP and statutory combined ratios for the three and nine months ended September 30, 2025 and 2024:

Loss Ratio

For the third quarter of 2025, the loss ratio increased slightly to 62.1%, compared to 61.5% for the third quarter of 2024. For the commercial lines segment, the core loss ratio, which excludes weather-related losses, large fire losses and net development of reserves for losses incurred in prior accident years, of 54.0% for the third quarter of 2025 increased from 48.5% for the third quarter of 2024, due largely to higher casualty loss severity. For the personal lines segment, the core loss ratio of 46.6% for the third quarter of 2025 decreased from 52.5% for the third quarter of 2024, due largely to the favorable impact of premium rate increases on net premiums earned for that segment.

Weather-related losses were $14.3 million, or 6.2 percentage points of the loss ratio, for the third quarter of 2025, compared to $24.4 million, or 10.3 percentage points of the loss ratio, for the third quarter of 2024. Weather-related loss activity for the third quarter of 2025 was lower than our previous five-year average of $20.9 million, or 10.0 percentage points of the loss ratio, for third-quarter weather-related losses. The weather loss ratio impact for the third quarter of 2025 was the lowest of any third quarter in the past 20 years. Our insurance subsidiaries did not incur losses from any catastrophic weather events in the third quarter of 2025, compared to $6.0 million in net losses from Hurricane Helene in the third quarter of 2024.

Large fire losses, which we define as individual fire losses in excess of $50,000, for the third quarter of 2025 were $10.0 million, or 4.4 percentage points of the loss ratio. That amount compared to large fire losses of $8.8 million, or 3.7 percentage points of the loss ratio, for the third quarter of 2024. We experienced a modest increase in homeowners fire losses compared to the prior-year quarter.

Net development of reserves for losses incurred in prior accident years of $1.0 million increased the loss ratio for the third quarter of 2025 by 0.4 percentage points, compared to net favorable development of $6.2 million that decreased the loss ratio for the third quarter of 2024 by 2.6 percentage points. For the third quarter of 2025, we primarily attribute the modest net unfavorable development to higher-than-expected emergence that our insurance subsidiaries experienced for a relatively small number of claims in the personal automobile and other commercial lines of business for accident years 2022 and 2024.

Expense Ratio

The expense ratio was 33.5% for the third quarter of 2025, compared to 34.5% for the third quarter of 2024. The decrease in the expense ratio primarily reflected the favorable impact of ongoing expense management initiatives and lower underwriting-based incentive costs for agents and employees. The impact of underwriting-based incentive costs for the third quarter of 2024 was somewhat elevated due to the substantial improvement in underwriting results for that period compared to the first half of 2024. The impact from costs that Donegal Mutual Insurance Company allocated to our insurance subsidiaries related to its ongoing systems modernization project peaked at approximately 1.3 percentage points of the full year 2024 expense ratio, and we expect that impact to subside gradually over the next several years. Allocated costs related to that project represented approximately 1.2 percentage point of the expense ratios for the third quarter and first nine months of 2025.

Investment Operations

Donegal Group’s investment strategy is to generate an appropriate amount of after-tax income on its invested assets while minimizing credit risk through investment in high-quality securities. As a result, we had invested 94.6% of our consolidated investment portfolio in diversified, highly rated and marketable fixed-maturity securities at September 30, 2025.

Average tax-equivalent investment yield		3.7	%				3.4	%

Net investment income of $13.9 million for the third quarter of 2025 increased 28.8% compared to $10.8 million for the third quarter of 2024. The increase in net investment income primarily reflected an increase in average investment yield relative to the prior-year third quarter.

Net investment gains of $1.3 million for the third quarter of 2025 were primarily related to unrealized gains in the fair value of equity securities held at September 30, 2025, offset partially by net realized investment losses on the strategic sales of available-for-sale fixed-maturity securities. Net investment gains of $1.9 million for the third quarter of 2024 were primarily related to unrealized gains in the fair value of equity securities held at September 30, 2024.

Our book value per share was $17.14 at September 30, 2025, compared to $15.36 at December 31, 2024, with the increase related to net income as well as $16.0 million of after-tax unrealized gains within our available-for-sale fixed-maturity portfolio during 2025 that increased our book value by $0.46 per share, offset partially by cash dividends declared.

Definitions of Non-GAAP Financial Measures

We prepare our consolidated financial statements on the basis of GAAP. Our insurance subsidiaries also prepare financial statements based on statutory accounting principles state insurance regulators prescribe or permit (“SAP”). In addition to using GAAP-based performance measurements, we also utilize certain non-GAAP financial measures that we believe provide value in managing our business and for comparison to the financial results of our peers. These non-GAAP measures are net premiums written, operating income or loss and statutory combined ratio.

Net premiums written and operating income or loss are non-GAAP financial measures investors in insurance companies commonly use. We define net premiums written as the amount of full-term premiums our insurance subsidiaries record for policies effective within a given period less premiums our insurance subsidiaries cede to reinsurers. We define operating income or loss as net income or loss excluding after-tax net investment gains or losses, after-tax restructuring charges and other significant non-recurring items. Because our calculation of operating income or loss may differ from similar measures other companies use, investors should exercise caution when comparing our measure of operating income or loss to the measure of other companies.

The following table provides a reconciliation of net premiums earned to net premiums written for the periods indicated:

The statutory combined ratio is a non-GAAP standard measurement of underwriting profitability that is based upon amounts determined under SAP. The statutory combined ratio is the sum of:

the statutory loss ratio, which is the ratio of calendar-year incurred losses and loss expenses, excluding anticipated salvage and subrogation recoveries, to premiums earned;
the statutory expense ratio, which is the ratio of expenses incurred for net commissions, premium taxes and underwriting expenses to premiums written; and
the statutory dividend ratio, which is the ratio of dividends to holders of workers’ compensation policies to premiums earned.

The statutory combined ratio does not reflect investment income, federal income taxes or other non-operating income or expense. A statutory combined ratio of less than 100% generally indicates underwriting profitability.

Dividend Information

On October 16, 2025, we declared a regular quarterly cash dividend of $0.1825 per share for our Class A common stock and $0.165 per share for our Class B common stock, which are payable on November 17, 2025 to stockholders of record as of the close of business on November 3, 2025.
