Second Quarter and Six Month Results

•

Second quarter core net operating earnings $.91 per share

•

Growth in book value per share, excluding appropriated retained earnings, 40% since 12/31/07; 12% in 2010

•

Repurchased 2.7 million shares during the quarter (average price $27.82 per share)

Increased 2010 core earnings guidance to $3.55 — $3.85 per share

Cincinnati, Ohio — August 2, 2010 — American Financial Group, Inc. (NYSE/NASDAQ: AFG) today reported net earnings attributable to shareholders of $108 million ($0.97 per share) for the 2010 second quarter, compared to $127 million ($1.09 per share) reported for the 2009 second quarter. The 2010 results reflect realized gains on investments of $6 million, compared to $10 million in the 2009 period. Book value per share, excluding appropriated retained earnings, increased by $2.02 to $37.48 per share during the quarter. Net earnings for the first six months of 2010 were $214 million ($1.90 per share) compared to $231 million ($1.98 per share) for the same period a year ago.

Core net operating earnings of $102 million ($0.91 per share) for the 2010 second quarter were consistent with our expectations, but down 13% percent from the record results in the 2009 comparable period. Improved results in the annuity and supplemental insurance group were offset by lower underwriting profit in our specialty property and casualty insurance (“P&C”) operations resulting from higher weather-related losses and lower investment income. Core net operating earnings for the first six months of 2010 were $205 million ($1.82 per share) compared to $248 million ($2.13 per share) for the same period a year ago. Six month annualized core operating return on equity was 10%.

During the second quarter of 2010, AFG repurchased 2.7 million shares of common stock at an average price per share of $27.82.

AFG’s net earnings attributable to shareholders, determined in accordance with generally accepted accounting principles (“GAAP”), include certain items that may not be indicative of its ongoing core operations. The following table identifies such items and reconciles net earnings attributable to shareholders to core net operating earnings, a non-GAAP financial measure that AFG believes is a useful tool for investors and analysts in analyzing ongoing operating trends.

Carl Lindner III and Craig Lindner, AFG’s Co-Chief Executive Officers, issued this statement: “AFG’s results for the second quarter and first six months of 2010 demonstrate our ability to navigate continued challenges in the insurance marketplace. The specialty nature and mix of our insurance businesses serve us well in this environment. We have posted solid core operating earnings and continue to see a meaningful improvement in the market value of our investment portfolio.

“We continue to evaluate effective ways to deploy our excess capital to achieve appropriate returns on shareholders’ equity. Through June 30, 2010, AFG has repurchased over 5.6 million shares of its common stock, representing approximately 5 percent of shares outstanding at the beginning of 2010. We believe that purchasing shares at attractive prices is an effective use of our excess capital, producing a favorable effect on our earnings per share and book value per share. Growth in AFG’s book value per share is a key strategic benchmark in measuring value creation for our shareholders. Since the end of 2007, AFG has grown its book value per share, excluding appropriated retained earnings, by 40%.

“Earlier today, we renewed our $500 million bank line, which strengthens our financial flexibility. The financial leverage and capital in our insurance businesses are at levels that fully support our operations and are consistent with our commitments to rating agencies.

“Based on our results for the first half of the year, we increased our 2010 core operating earnings guidance to $3.55 to $3.85 per share, up from $3.30 to $3.70 per share. As has been our practice, this guidance excludes realized gains and losses, as well as the potential for significant catastrophe and crop losses and unforeseen major adjustments to asbestos and environmental reserves, and unlocking adjustments related to annuity deferred acquisition costs.”

Business Segment Results

The P&C specialty insurance operations generated an underwriting profit of $68 million in the 2010 second quarter, compared to $112 million in the second quarter of 2009. The reduced profit in 2010 is primarily the result of $34 million (6 points on the combined ratio) in catastrophe losses, compared to $11 million (2 points) in the 2009 second quarter. Favorable reserve development was $62 million (11 points) compared to $80 million (13 points) in 2009. Underwriting profit of the P&C specialty insurance operations for the first six months of 2010 was $145 million, 33% lower than the comparable 2009 period.

Gross and net written premiums were lower in the 2010 second quarter and first six months compared to the 2009 periods. Further details of the P&C Specialty operations may be found in the accompanying schedules.

The Property and Transportation group reported an underwriting profit of $8 million in the second quarter of 2010, compared to $26 million in the second quarter of 2009. This decrease is largely attributable to a $22 million increase in catastrophe losses resulting primarily from hail storms in Oklahoma during the month of May. Favorable reserve development served to offset these results somewhat. Underwriting profit in the first six months of 2010 decreased approximately $34 million from the comparable 2009 period. Gross written premiums for the second quarter and first six months of 2010 were impacted by a competitive pricing environment as well as lower spring commodity prices that have the effect of lowering our crop premium volume. In 2010, we returned to historical levels of cessions under our crop reinsurance agreement, contributing to an 8% increase to this group’s net written premiums for the first half of 2010 compared to the 2009 period. Excluding crop, this group’s net written premiums for the first six months decreased by 1% from the prior year.

The Specialty Casualty group reported an underwriting profit of $23 million in the second quarter of 2010, compared to $38 million in the second quarter of 2009. Underwriting profit in the first six months of 2010 decreased approximately $37 million from the comparable 2009 period. Both periods include the results of our California Workers’ Compensation business, which was previously reported as a separate operating group. Lower underwriting results in our general liability operations, (primarily those that serve the homebuilders industry), excess and surplus lines and our California workers’ compensation businesses were offset somewhat by improvements in our executive liability and targeted markets operations. Many businesses in this group produced strong underwriting profit margins, but at lower levels than in 2009. Gross and net written premiums for the first six months of 2010 were down 8% and 7%, respectively, from the same 2009 period. A soft pricing environment and competitive market conditions in the excess and surplus markets and California workers’ compensation business, as well as volume reductions resulting from decreased demand for general liability coverages in the homebuilders market contributed to these declines. Growth in gross and net written premiums in our Marketform, executive liability and environmental operations partially offset these declines.

The Specialty Financial group reported underwriting profits of $33 million in the second quarter of 2010 compared to $54 million in the same 2009 period. Improvements in used car sales prices resulted in $13 million in favorable reserve development in this group’s automobile residual value insurance (RVI) business, compared to $39 million of favorable development in the second quarter of 2009. Our remaining $23 million of Canadian RVI reserves relate to leases that terminate through the end of 2010. Specialty Financial underwriting profits were $54 million for the six month period, compared to $67 million in the same 2009 period. All other lines of business in this group produced excellent underwriting results, but at lower levels than the prior year. Gross and net written premiums decreased approximately 8% and 13%, respectively, from the 2009 first six months primarily due to economic conditions affecting the automotive industry. In addition, net written premiums were impacted by a decision to exit certain automotive lines of business during 2009.

Carl Lindner III stated, “Increased catastrophes during the second quarter coupled with a continued soft pricing environment and competitive market conditions have been challenging for our property and casualty businesses; however, we remain on target to achieve our 2010 operating goals. We continue to focus on writing quality business that will produce appropriate returns. Through the first six months of 2010, our businesses continued to achieve solid underwriting profits, albeit at lower levels than in 2009. Pricing for the quarter and first six months was flat overall and we continue to monitor rate adequacy in our markets. We know that it is important to gauge business growth based on our ability to achieve adequate pricing, but we also want to be well positioned for a market turn.”

Annuity and Supplemental Insurance Core Results

The Annuity and Supplemental Insurance Group generated core operating earnings before income taxes of $46 million for the 2010 second quarter, compared to $42 million in the 2009 period. The increase was primarily attributable to higher operating earnings in the fixed annuity and supplemental insurance operations, which were partially offset by lower earnings in our variable annuity operations. Core operating earnings before income taxes for the first half of 2010 were 11% higher than the comparable 2009 period.

Statutory premiums of $671 million and $1.2 billion in the 2010 second quarter and first six months were 31% and 32% higher, respectively, than the comparable periods in 2009. These results reflect increased sales of single premium annuities and higher sales in the bank market.

Due to the two-tier nature and other surrender protection features in certain of its annuity products, AFG continues to experience strong persistency in its annuity businesses.

A&E Reserve Study

During the second quarter, AFG completed an internal review of its asbestos and environmental exposures relating to the run-off operations of its P&C group and its exposures related to former railroad and manufacturing operations and sites. We conduct similar studies with the assistance of outside actuaries and specialty outside counsel every two years and perform an in-depth internal study during the intervening years. This year’s study resulted in a net reserve adjustment of less than $5 million on an after-tax basis. During the course of this year’s study, there were no newly identified emerging trends or issues that management believes significantly impact the overall adequacy of AFG’s A&E reserves.

At June 30, 2010, AFG’s three year survival ratio for property and casualty exposures was 9.6 times paid losses for asbestos reserves and 8.5 times paid losses for total A&E reserves. These ratios compare favorably with industry data published by Conning Research and Consulting, Inc. in May 2010, which indicate that A&E survival ratios were 8.2 for asbestos reserves and 7.7 for total industry A&E reserves at December 31, 2009.

Investments

AFG recorded second quarter 2010 net realized gains of $6 million after tax and after DAC, compared to $10 million in the prior year period. After-tax, after-DAC realized gains for the first six months of 2010 were $9 million, compared to realized losses of $17 million in the same period in 2009. Unrealized gains on fixed maturities were $287 million, after tax, after DAC, an increase of $239 million since December 31, 2009. Our portfolio continues to be high quality, with 91% of our fixed maturity portfolio rated investment grade and 95% with a National Association of Insurance Commissioners’ designation of NAIC 1 or 2, its highest two categories.
