NEW YORK – May 9, 2007 – ACA Capital Holdings, Inc. (NYSE: ACA) today announced first quarter 2007 net income of $11.4 million, or $0.31 per diluted share.  This represents a 19% decrease from first quarter 2006 net income of $14.1 million, and a 34% decrease from first quarter 2006 earnings per diluted share of $0.47.  The decrease in net income was primarily a result of net unrealized mark-to-market losses on the Company’s portfolio of Structured Credit transactions.

Net income and net income per diluted share are computed in accordance with accounting principles generally accepted in the United States of America (“GAAP”).  Additionally, to assist investors in their understanding of the Company’s quarterly results and their measurement of the Company’s growth and profitability, ACA Capital provides other non-GAAP information, including net economic income and base economic income.

Net economic income for the first quarter of 2007 was $15.7 million, or $0.42 per diluted share.  This represents a 41% increase from first quarter 2006 net economic income of $11.1 million, and a 14% increase from first quarter 2006 net economic income per diluted share of $0.37.

Base economic income for the first quarter of 2007 was $15.4 million, or $0.42 per diluted share.  This represents a 41% increase from first quarter 2006 base economic income of $10.9 million, and a 17% increase from first quarter 2006 base economic income per diluted share of $0.36.

“ACA Capital’s economic results for the first quarter underscore our ability to produce significant growth throughout changing market conditions” said President and Chief Executive Officer Alan S. Roseman. “Our Structured Credit business’ revenue growth continues to exceed even our ambitious objectives.  In addition, we added $1.6 billion of new CDO assets under management despite the uncertainties in the asset-backed CDO market, and we can already see positive results from renewed efforts in our Public Finance business.  Given these successes, we remain very optimistic and excited for the balance of 2007.”
