Radian Reports First Quarter Net Income of $195.6 Million

Results Reflect After-Tax Net Unrealized Mark-To-Market Gains of $410.9 Million

PHILADELPHIA, May 12, 2008 - Radian Group Inc. (NYSE: RDN) (the “Company”) today reported net income of $195.6 million and diluted earnings per share of $2.44 for the quarter ended March 31, 2008. Book value per share at March 31, 2008 was $35.64. Excluding the impact of net unrealized gains on derivatives and hybrid securities, the Company’s net operating loss was $215.2 million and the net operating loss per share was $2.69 for the quarter. “Net operating loss” and “net operating loss per share” are non-GAAP financial measures. A discussion of these measures, including a reconciliation to pre tax income, is included below.

Radian’s financial results for the first quarter of 2008 were significantly impacted by unrealized gains and losses on the Company’s hybrid securities and derivative assets and liabilities. Credit spreads on underlying collateral, both corporate credit spreads and asset-backed spreads, widened significantly during the quarter, which resulted in large unrealized losses on these

positions. Offsetting these losses, however, is the impact of a change to the Company’s valuation methodology, which is adopted prospectively, that incorporates the market’s perception of Radian’s non-performance risk. This change in methodology is required under the provisions of SFAS No. 157. Given the significant widening of Radian’s credit default swap spread over the past year, the reduction in the valuation of the Company’s derivative liabilities related to non-performance risk more than offset the credit spread widening on underlying collateral for the current quarter. Below is a table with the detail of the impact on Radian’s quarterly results of underlying collateral credit spread widening and the aggregate impact of incorporation of Radian’s non-performance risk on our derivative instrument fair values.

“We have seen the continuation of weak housing and credit markets and these conditions have impacted results in our mortgage insurance and financial guaranty businesses,” said S.A. Ibrahim, Chief Executive Officer of Radian. “As previously announced, we are considering a range of alternatives to strengthen our capital position, while at the same time considering the alternatives for our financial guaranty business which offer the best long term value. Our liquidity and claims paying capabilities remain strong across both business units.”

In the mortgage insurance business, paid claims during the first quarter were in line with the Company’s guidance. As of March 31, 2008, Radian had $1.7 billion in mortgage insurance loss reserves. Newly written product mix in the mortgage insurance business continued to shift significantly to prime loans, with 90% of production during the first quarter made up of prime business, up from 77% during the fourth quarter.

Mr. Ibrahim continued, “By focusing on prime loans, working closely with the Government Sponsored Enterprises and managing our existing Risk-In-Force exposure, Radian will continue to address the significant challenges in the housing markets and overall economic environment.”

Radian’s financial guaranty business continues to maintain a strong capital position with limited exposure to vulnerable asset classes. Although new written premiums declined approximately 21% from the first quarter of 2007, reinsurance business remained strong.

Radian will discuss each of these items in its conference call today, Monday, May 12, 2008, at 10:00 a.m. Eastern time. The conference call will be broadcast live over the

Non-GAAP Measures

The table set forth above reconciles “net operating loss” and “net operating loss per share” to pretax income. In order to assist investors in understanding our quarterly operating results, which recently have been impacted significantly by changes in market values of our derivative and hybrid securities portfolios, we define our net operating earnings to be our GAAP pretax income, adjusted to exclude unrealized gains and losses on these portfolios that relate to market risk, as tax-affected. Net operating earnings is not a substitute for pretax income computed in accordance with GAAP, but is a useful measure of performance used by management, equity analysts and investors because it allows a more consistent period-to-period comparison of our earnings without the effects of unrealized gains and losses on derivatives and hybrid securities. The definition of operating earnings used by us may differ from definitions of operating earnings used by other companies.

All statements in this news release that address events, developments or results that we expect or anticipate may occur in the future are “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, Section 21E of the Securities Exchange Act of 1934 and the U.S. Private Securities Litigation Reform Act of 1995. These statements, which include, without limitation, projections regarding our future performance and financial condition are made on the basis of management’s current views and assumptions with respect to future events. Any forward-looking statement is not a guarantee of future performance and actual results could differ materially from those contained in the forward looking information. The forward-looking statements, as well as our prospects as a whole, are subject to risks and uncertainties, including the following:

• actual or perceived changes in general financial and political conditions, such as extended national or regional economic recessions, changes in housing demand or mortgage originations, changes in housing values (in particular, further deterioration in the housing, mortgage and related credit markets, which would harm our future consolidated results of operations and could cause losses for our mortgage insurance business to be worse than expected), changes in the liquidity in the capital markets and the further contraction of credit markets, population trends and changes in household formation patterns, changes in unemployment rates, changes or volatility in interest rates or consumer confidence, changes in credit spreads, changes in the way investors perceive the strength of private mortgage insurers or financial guaranty providers, investor concern over the credit quality and specific risks faced by the particular businesses, municipalities or pools of assets covered by our insurance;

• actual or perceived economic changes or catastrophic events in geographic regions (both domestic and international) where our mortgage insurance or financial guaranty insurance in force is more concentrated;

• our ability to successfully obtain additional capital to support our long-term liquidity needs and to protect our credit and financial strength ratings;

• a decrease in the volume of home mortgage originations due to reduced liquidity in the lending market, tighter underwriting standards and a deterioration in housing markets throughout the U.S.;

• a decrease in the volume of the municipal bonds, and other public finance and structured finance transactions that we insure, or a decrease in the volume of such transactions for which issuers or investors seek or demand financial guaranty insurance;

• the loss of a customer for whom we write a significant amount of mortgage insurance or financial guaranty insurance or the influence of large customers;

• reduction in the volume of reinsurance business available to us from one or more of our primary financial guaranty insurer customers due to adverse changes in their ability to generate new profitable direct financial guaranty insurance or their need for us to reinsure their risk;

• disruption in the servicing of mortgages covered by our insurance policies;

• the aging of our mortgage insurance portfolio and changes in severity or frequency of losses associated with certain of our products that are riskier than traditional mortgage insurance or financial guaranty insurance policies;

• the performance of our insured portfolio of higher risk loans, such as Alternative-A (“Alt-A”) and subprime loans, and adjustable rate products, such as adjustable rate mortgages and interest-only mortgages, which have resulted in increased losses in 2007 and 2008 and may result in further losses;

• reduced opportunities for loss mitigation in markets where housing values fail to appreciate or begin to decline;

• changes in persistency rates of our mortgage insurance policies caused by changes in refinancing activity, in the rate of appreciation or depreciation of home values and changes in the mortgage insurance cancellation requirements of mortgage lenders and investors;

• downgrades or threatened downgrades of, or other ratings actions with respect to, our credit ratings or the insurance financial strength ratings assigned by the major rating agencies to any of our rated insurance subsidiaries at any time (in particular, our credit rating and the financial strength ratings of our mortgage insurance subsidiaries that are currently under review for possible downgrade);

• heightened competition for our mortgage insurance business from others such as the Federal Housing Administration and the Veterans’ Administration or other private mortgage insurers (in particular those that have been assigned higher ratings from the major ratings agencies), from alternative products such as “80-10-10” loans or other forms of simultaneous second loan structures used by mortgage lenders, from investors using forms of credit enhancement other than mortgage insurance as a partial or complete substitution for private mortgage insurance and from mortgage lenders that demand increased participation in revenue sharing arrangements such as captive reinsurance arrangements;

• changes in the charters or business practices of Federal National Mortgage Association and Freddie Mac, the largest purchasers of mortgage loans that we insure, and our ability to retain our “Top Tier” eligibility requirement from both Freddie Mac and Fannie Mae;

• failure to bring the amendment to our credit facility, dated April 30, 2008, effective by May 15, 2008, which would result in a reinstatement of the ratings covenant under our credit facility;

• heightened competition for financial guaranty business from other financial guaranty insurers, including those recently downgraded to ratings equal to or lower than our ratings, from other forms of credit enhancement such as letters of credit, guaranties and credit default swaps provided by foreign and domestic banks and other financial institutions and from alternative structures that may permit insurers to securitize assets more cost-effectively without the need for the types of credit enhancement we offer, or result in our having to reduce the premium we charge for our products;

• the application of existing federal or state consumer, lending, insurance, securities and other applicable laws and regulations, or changes in these laws and regulations or the way they are interpreted; including, without limitation: (i) the possibility of private lawsuits or formal investigations by state insurance departments and state attorneys general alleging that services offered by the mortgage insurance industry, such as captive reinsurance, pool insurance and contract underwriting, are violative of the Real Estate Settlement Procedures Act and/or similar state regulations, (ii) legislative and regulatory changes affecting demand for private mortgage insurance or financial guaranty insurance, or (iii) legislation and regulatory changes limiting or restricting our

use of (or requirements for) additional capital, the products we may offer, the form in which we may execute the credit protection we provide or the aggregate notional amount of any product we may offer for any one transaction or in the aggregate;

• the possibility that we may fail to estimate accurately the likelihood, magnitude and timing of losses in connection with establishing loss reserves for our mortgage insurance or financial guaranty businesses, or the premium deficiency for our second-lien mortgage insurance business, or to estimate accurately the fair value amounts of derivative contracts in our mortgage insurance and financial guaranty businesses in determining gains and losses on these contracts;

• changes in accounting guidance from the Securities and Exchange Commission (“SEC”) or the Financial Accounting Standards Board;

• our ability to profitably grow our insurance businesses in international markets, which depends on a number of factors such as foreign governments’ monetary policies and regulatory requirements, foreign currency exchange rate fluctuations, and our ability to develop and market products appropriate to foreign markets;

• legal and other limitations on the amount of dividends we may receive from our subsidiaries; and

• vulnerability to the performance of our strategic investments, including in particular, our investment in Sherman Financial Group LLC.
