American Financial Group Announces Second Quarter Results

Cincinnati, Ohio July 31, 2003 - American Financial Group, Inc. (NYSE: AFG) today reported net earnings for the 2003 second quarter of $30.5 million ($.44 per share). These results included an after-tax charge of $28.5 million ($.41 per share) for the effect of a previously announced arbitration decision relating to an AFG insurance subsidiary's share of a 1995 property claim, and a $6.7 million ($.10 per share) charge representing AFG's portion of a charge recorded within the fixed annuity operations related to the negative effect of lower interest rates. These charges were partly offset by net realized gains of $16.1 million ($.23 per share). AFG's net earnings for last year's second quarter were $12.1 million ($.17 per share) which included net realized losses of $28.3 million ($.42 per share).

Carl H. Lindner, AFG Chairman and Chief Executive Officer stated, "We continue to benefit from the hard market conditions and price firming in the commercial casualty markets. We are pleased with the operating results of our ongoing insurance operations and expect these positive trends to continue. I remain comfortable with our previously announced 2003 core earnings guidance of $2.10 to $2.30. We were also pleased with the June sale of senior convertible notes, resulting in net proceeds of approximately $185 million, a portion of which was used to pay off our revolving bank line while the remainder is being used in operations."

Business Segment Results

The combined ratio of the P&C Group for the 2003 second quarter, before adding 10.6 points for the above-mentioned charge, was 96.5% compared to 101.1% for the same period a year ago. The group's premiums and underwriting results for the 2003 second quarter included AFG's direct auto insurance companies through the date of their sale at the end of April.

The Specialty Group reported an underwriting profit for the 2003 second quarter with a combined ratio of 95.7%, an improvement of 2.3 points over the 2002 second quarter. The Group's gross written premiums for the 2003 quarter grew approximately 24% compared with the 2002 period, reflecting the effect of continuing rate increases in most of its businesses. The Group's net written premiums grew at a lower rate of 14% over the 2002 period, primarily due to a reinsurance agreement put into place in the 2002 fourth quarter.

Carl H. Lindner III, AFG Co-President and head of the P&C Group commented: "Our Specialty Group generated another solid underwriting profit for the seventh consecutive quarter. A majority of our ongoing lines of business achieved a growth rate of over 20% in gross written premiums through the first half of the year and most of our individual business units continue to report underwriting profitability. Even though the group's 2003 second quarter underwriting results included about $36 million, or 9 points, of adverse development related to claims from 1999 and 2000, the group's performance continues to be in line with our objectives for 2003. Our operations experienced average rate increases of 27% and 23% in the first and second quarters, respectively, and should continue to benefit from the favorable pricing environment. We are targeting average rate increases of around 20% for the remainder of 2003."

Mr. Lindner continued, "In addition, our overall results benefited from our continuing ownership interest in Infinity which reported strong operating results for the 2003 second quarter. The market has recognized Infinity's value as evidenced by the increase in its stock price of about 65% since the initial public offering. Also in July, Infinity obtained a $200 million credit facility and repaid the $55 million promissory note we held."

Statutory premiums of the Annuity, Life and Health insurance operations for the 2003 second quarter were 10% higher than the 2002 period, reflecting the addition of several new fixed annuity agents and products. The net operating earnings of $9.3 million for the second quarter of 2003 were below the 2002 period of $21.5 million due primarily to lower spread income and an after-tax charge of $8.1 million in the fixed annuity operations. This charge reflects adjustments to certain balance sheet items, including deferred policy acquisition costs, that are calculated in part based on estimated future spreads on the company's block of in-force fixed annuities. Further details may also be found in the earnings release issued today by Great American Financial Resources, Inc. (NYSE:GFR). AFG owns 82% of GFR common stock and a proportional share of its earnings is included in AFG's results.

AFG's net earnings for the first half of 2003 were $55.6 million ($.80 per share) compared to $13.5 million ($.19 per share) for the same 2002 period. Core earnings from insurance operations for the first half of 2003 were $58.9 million ($.84 per share), including the charges for the arbitration decision and annuity operations, compared to $79.7 million ($1.15) for the 2002 period. Excluding these charges, the underlying operating earnings for the first half of 2003 were about 18% higher than the 2002 period. Details of the financial results may be found in the accompanying schedules.

The combined ratio of AFG's P&C Group for the first six months of 2003, before a 4.6 point charge for the arbitration decision, was 96.9% compared to 101.4% in the 2002 period. The Specialty Group's combined ratio for the 2003 period was 96.8%; its gross written premiums increased about 22% over the 2002 period while net written premiums for this same period were only 14% higher due to certain reinsurance agreements mentioned above.

Actual results could differ materially from those expected by AFG depending on certain factors including but not limited to: the unpredictability of possible future litigation if certain settlements do not become effective, changes in economic conditions including interest rates, performance of securities markets, and the availability of capital, regulatory actions, changes in legal environment, judicial decisions and rulings, tax law changes, levels of catastrophes and other major losses, the actual amount of liabilities associated with certain asbestos and environmental related insurance claims, adequacy of loss reserves, availability of reinsurance and ability of reinsurers to pay their obligations, competitive pressures, including the ability to obtain rate increases, driving patterns and other changes in market conditions that could affect AFG's insurance operations.
