“During this quarter, our casualty businesses performed well and our investment results continued to be solid as reflected by our book value growth. These positive results were partially offset by significant losses in our property businesses. As a result, we determined certain segments of our property businesses were not achieving our profitability targets. Consequently, we are scaling back these segments and focusing on the segments that we believe will meet our profitability targets,” said Richard H. Smith, Chairman, President and Chief Executive Officer.

Net income for the second quarter of 2009 was $11.6 million compared to $28.7 million for the same period of 2008. Net income for the first six months of 2009 was $20.3 million compared to $38.4 million for the same period of 2008. Net income for the three and six months ended June 30, 2008 included $22.5 million and $23.6 million, respectively, of income from discontinued operations, which includes a gain on the sale of ARPCO of $21.4 million. Operating net income for the second quarter of 2009 was $5.3 million compared to $7.2 million for the same period of 2008. Operating net income for the first six months of 2009 was $12.8 million compared to $16.2 million for the same period of 2008.

As a result of these losses, the Company has significantly tightened the underwriting criteria for all property classes and cancelled certain in-force property policies mid-term. In addition, the Company has provided notice of cancellation to the contract underwriter responsible for a portion of the Company’s property business and has significantly restricted the contract underwriter’s authority to bind business on the Company’s behalf through the termination date.

Smith concluded, “While current market and economic conditions remain competitive, we believe we are positioned to benefit from improving market conditions and we continue to focus on disciplined underwriting and prudent capital management. Given the higher than expected 2009 property losses and the scaling back of certain property segments, we are reducing our guidance of operating net income per diluted share from between $1.60 to $1.75 to between $1.30 to $1.60 for all of 2009. The range has been expanded to provide for the variability embedded in the property business net unearned premium reserves.”

About First Mercury Financial Corporation

First Mercury Financial Corporation provides insurance products and services primarily to the specialty commercial insurance markets, focusing on niche and underserved segments where we believe that we have underwriting expertise and other competitive advantages.  During the Company’s 36 years of underwriting risks, First Mercury has developed the underwriting expertise and cost-efficient infrastructure which has enabled us to effectively underwrite such risks. Our risk-taking subsidiaries offer insurance products through our distribution subsidiaries: CoverX^®, FM Emerald and AMC, which are recognized brands among insurance producers.

Non-GAAP Financial Measures

Operating net income and operating net income per share are non-GAAP financial measures, and management believes that investors’ understanding of core operating performance is enhanced by First Mercury’s disclosure of these financial measures. Operating net income consists of net income adjusted to exclude the impact of net realized gains (losses) on investments, other-than-temporary impairment losses on investments, the change in fair value of derivative instruments, income from discontinued operations, and taxes related to these adjustments. Definitions of these items may not be comparable to the definitions used by other companies. Net income and net income per share are the GAAP financial measures that are most directly comparable to operating net income and operating net income per share.
