CINCINNATI – August 6, 2024 – American Financial Group, Inc. (NYSE: AFG) today reported 2024 second quarter net earnings of $209 million ($2.49 per share) compared to $200 million ($2.34 per share) for the 2023 second quarter. Net earnings for the 2024 second quarter included after-tax non-core losses of $6 million ($0.07 per share loss). By comparison, net earnings in the 2023 second quarter included net after-tax non-core items that reduced net income by $2 million ($0.04 per share loss).

Other details may be found in the table on the following page.

Core net operating earnings were $215 million ($2.56 per share) for the 2024 second quarter, compared to $202 million ($2.38 per share) in the 2023 second quarter, reflecting meaningfully higher P&C underwriting profit. Additional details for the 2024 and 2023 second quarters may be found in the table below. Core net operating earnings for the second quarters of 2024 and 2023 generated annualized returns on equity of 18.5% and 18.2%, respectively, which is calculated excluding AOCI.

AFG’s book value per share was $52.25 at June 30, 2024. AFG paid cash dividends of $0.71 per share during the second quarter. For the three months ended June 30, 2024, AFG’s growth in book value per share plus dividends was 4.7% and year to date, growth in book value per share plus dividends was 10.3%.

Book value per share excluding AOCI was $56.19 at June 30, 2024. For the three months ended June 30, 2024, AFG’s growth in book value per share excluding AOCI plus dividends was 4.7%. Year to date, growth in book value per share excluding AOCI plus dividends was 9.9%.

AFG’s net earnings, determined in accordance with U.S. generally accepted accounting principles (GAAP), include certain items that may not be indicative of its ongoing core operations. The table below identifies such items and reconciles net earnings to core net operating earnings, a non-GAAP financial measure.

Page 1

AFG believes that its core net operating earnings provides management, financial analysts, ratings agencies, and investors with an understanding of the results from the ongoing operations of the Company by excluding the impact of net realized gains and losses and other items that are not necessarily indicative of operating trends. AFG’s management uses core net operating earnings to evaluate financial performance against historical results because it believes this provides a more comparable measure of its continuing business. Core net operating earnings is also used by AFG’s management as a basis for strategic planning and forecasting.

Carl H. Lindner III and S. Craig Lindner, AFG’s Co-Chief Executive Officers, issued this statement: “We are pleased to report a second quarter annualized core operating return on equity of 18.5%. Underwriting margins in our specialty P&C insurance businesses were strong, and higher interest rates increased net investment income, excluding alternatives, by 15% year over year. These results, coupled with effective capital management and our entrepreneurial, opportunistic culture and disciplined operating philosophy enable us to continue to create value for our shareholders.

Messrs. Lindner continued: “AFG continued to have significant excess capital at June 30, 2024. Returning capital to shareholders in the form of regular and special cash dividends and through opportunistic share repurchases is an important and effective component of our capital management strategy. In addition, our capital will be deployed into AFG’s core businesses as we identify the potential for healthy, profitable organic growth, and opportunities to expand our specialty niche businesses through acquisitions and start-ups that meet our target return thresholds.”

Specialty Property and Casualty Insurance Operations

The Specialty P&C insurance operations generated a strong 90.5% combined ratio in the second quarter of 2024, an improvement of 1.4 points from the 91.9% reported in the second quarter of 2023. Second quarter 2024 results include 2.3 points related to catastrophe losses, compared to 3.5 points in the 2023 second quarter. Second quarter 2024 results benefited from 2.3 points of favorable prior year reserve development, compared to 4.0 points in the second quarter of 2023. Underwriting profit was $151 million for the 2024 second quarter compared to $123 million in the second quarter of the prior period.

Page 2

Second quarter 2024 gross and net written premiums were up 2% and 1%, respectively, when compared to the second quarter of 2023. We continue to achieve year-over-year premium growth as a result of a combination of new business opportunities, increased exposures, and a good renewal rate environment, which was partially offset by later reporting of crop premiums. Tempered growth in the quarter also reflects the Company’s proactive and intentional approach to managing exposure in several of our social inflation-exposed businesses.

Average renewal pricing across our P&C Group, excluding workers’ compensation, was up approximately 8% for the quarter, and up approximately 6% overall, consistent with pricing increases achieved in the first quarter. We believe we are achieving overall renewal rate increases in excess of prospective loss ratio trends to meet or exceed targeted returns.

The Property and Transportation Group reported an underwriting profit of $39 million in the second quarter of 2024, compared to $32 million in the second quarter of 2023. Higher year-over-year underwriting profits in our property & inland marine and crop insurance businesses were partially offset by lower underwriting profitability in our transportation businesses. Catastrophe losses in this group were $13 million in the second quarter of 2024, compared to $15 million in the second quarter of 2023. Overall, the businesses in the Property and Transportation Group achieved a 92.9% calendar year combined ratio in the second quarter, improving 1.3 points from the comparable period in 2023.

Second quarter 2024 gross and net written premiums in this group were both 2% higher than the comparable prior year. Year-over-year premium growth was primarily attributed to new business opportunities, a favorable rate environment and increased exposures in our commercial auto businesses. Later reporting of crop acreage, which impacts the timing of crop premiums, more than offset additional crop premium associated with the CRS acquisition. Excluding crop, gross and net written premiums in this group grew by 7% and 5%, respectively. Overall renewal rates in this group increased 8% on average in the second quarter of 2024, about a point lower than the pricing achieved in this group for the first quarter of 2024.

The Specialty Casualty Group achieved an excellent 85.4% calendar year combined ratio overall in the second quarter of 2024, an improvement of 1.2 points over the very strong 86.6% reported in the second quarter of 2023. Underwriting profit was $108 million in the second quarter of 2024, compared to $95 million in the second quarter of 2023. Higher year-over-year profitability in our targeted markets and workers’ compensation businesses and improved results in several other Specialty Casualty businesses were partially offset by lower levels of favorable prior year reserve development in our executive liability business and adverse development in our excess liability business. Catastrophe losses for this group were $5 million in the second quarter of 2024 compared to $8 million in the prior year quarter.

Second quarter 2024 gross and net written premiums increased 1% and 2%, respectively, when compared to the same prior year period. Approximately two-thirds of the businesses in this group reported year-over-year growth as a result of new business opportunities, higher rates and strong policy retention. This growth was partially offset by non-renewal of several large accounts and other underwriting actions taken in several of our targeted markets businesses. Excluding our workers’ compensation businesses, renewal rates for this group were up approximately 7% in the second quarter, about a point lower than the first quarter. Overall renewal rates in this group including workers’ compensation were up about 5% and consistent with the first quarter of 2024.

The Specialty Financial Group reported an underwriting profit of $25 million in the second quarter of 2024, compared to $10 million in the second quarter of 2023. The increase was primarily the result of higher underwriting profit in our financial institutions business. Catastrophe losses for this group were $17 million in the second quarter of 2024 compared to $19 million in the prior year quarter. This group continued to achieve excellent underwriting margins and reported a combined ratio of 89.7% for the second quarter of 2024, 5.3 points better than the 95.0% reported in the comparable period in 2023.

Page 3

Second quarter 2024 gross written premiums were flat and net written premiums were up 3% in this group, respectively, when compared to the prior year period. Growth in our financial institutions business was partially offset by a decision to pause writing of new intellectual property-related coverage in our Innovative Markets business. Renewal pricing in this group was up approximately 6% for the quarter, about 1 point lower than the previous quarter.

Carl Lindner III stated, “Underwriting profitability was very strong in our Specialty P&C businesses in the second quarter of 2024, and we continue to feel confident about the strength of our reserves. A continued favorable pricing environment and new business opportunities enabled us to selectively grow our Specialty P&C businesses. Growth in net written premium was about 4% for the first six months of the year, as timing of acreage reporting by farmers and underwriting actions in a few of our businesses tempered growth in the second quarter. We expect growth in net written premiums to be approximately 7% for the full year in 2024.”

Investments

Net Investment Income – For the quarter ended June 30, 2024, property and casualty net investment income was approximately 1% lower than the comparable 2023 period. Excluding the impact of alternative investments, net investment income in our property and casualty insurance operations for the three months ended June 30, 2024, increased 15% year-over-year as a result of the impact of higher interest rates and higher balances of invested assets. The annualized return on alternative investments was approximately 5.1% for the 2024 second quarter compared to 9.6% for the prior year quarter. Earnings from alternative investments may vary from quarter to quarter based on the reported results of the underlying investments, and generally are reported on a quarter lag. The average annual return on alternative investments over the five calendar years ended December 31, 2023, was approximately 13%.

Non-Core Net Realized Gains (Losses) – AFG recorded second quarter 2024 net realized losses on securities of $2 million ($0.02 per share loss) after tax, which included $2 million ($0.02 per share loss) in after-tax net losses to adjust equity securities that the Company continued to own at June 30, 2024, to fair value. By comparison, AFG recorded net realized losses on securities of $1 million ($0.02 per share loss) in the comparable 2023 period.

After-tax unrealized losses related to fixed maturities were $310 million at June 30, 2024. Our portfolio continues to be high quality, with 94% of our fixed maturity portfolio rated investment grade and 96% of our P&C fixed maturity portfolio with a National Association of Insurance Commissioners’ designation of NAIC 1 or 2, its highest two categories.
