Hatteras Financial Corp. Announces First Quarter 2010 Financial Results

For Immediate Release

WINSTON-SALEM, N.C. – (BUSINESS WIRE) – Hatteras Financial Corp. (NYSE: HTS) (“Hatteras” or the “Company”) today announced financial results for the quarter ended March 31, 2010.

First Quarter 2010 Highlights

• Net income of $1.21 per diluted share

• Net return on average equity of 18.57%

• Declared a $1.20 per share dividend

• Average net interest spread of 2.59%

• Quarter end book value per share of $25.48

• Annualized rate of scheduled and unscheduled principal repayments of 36.04%

• Annualized total expense ratio of 1.31% of shareholders’ equity

First Quarter 2010 Results

During the quarter ended March 31, 2010, the Company earned $1.21 per diluted share on net income of $43.7 million, compared to $1.28 per diluted share on net income of $46.3 million during the quarter ended December 31, 2009. The Company had more earning assets and a slightly lower cost of funds during the first quarter of 2010 as compared to the fourth quarter of 2009, the benefit of which was offset by higher premium amortization and lower yields on new assets.

Net interest income for the quarter ended March 31, 2010 was $45.8 million, compared to $49.5 million for the quarter ended December 31, 2009. The Company’s average earning assets increased to $6.7 billion for the first quarter of 2010 from $6.5 billion in the previous quarter, and the net interest margin decreased to 2.59% for the first quarter of 2010 from 2.90% in the previous quarter. The decrease in the net interest margin was driven in large part by the lower asset yields resulting from the March spike in repayments. The Company’s average repurchase agreement (repo) rate was relatively flat in the first quarter of 2010 compared to the previous quarter, and at March 31, 2010, was 0.25% on all outstanding short-term (less than 30 days) repo positions. Operating expenses were $3.1 million for the first quarter versus $3.2 million for the fourth quarter of 2009. This equates to an annualized expense ratio of 1.31% of shareholders’ equity based on average equity for the quarter ended March 31, 2010.

“We continue to be very pleased with the way the company is performing. As expected, our first quarter did see an increased rate of prepayments as Freddie Mac bought back seriously delinquent loans from their guaranteed mortgage pools,” said Michael R. Hough, the Company’s Chief Executive Officer. “Also as expected, these prepayments increased our amortization expense from the write-off of unamortized premiums on the assets repurchased. We expect that Fannie Mae’s buyback program initiated in March, will proportionately impact our portfolio through the second quarter and that Freddie Mac’s program has likely been completed. Our decision to hold on to these securities, which we own at attractive prices, proved to be a good one as they actually have gained value since then. Our thought has been that the long-term value of these securities mitigates the near term effects we experienced in the quarter. Aside from that, the core spread on the existing portfolio was fairly consistent as borrowing costs remained stable while yields declined slightly on new investments. Going forward, our focus remains squarely on mitigating interest rate risk while monitoring federal administration monetary and regulatory policy for any significant changes.”

The Company’s portfolio, consisting of Fannie Mae and Freddie Mac guaranteed mortgage securities (agency securities), decreased to $6.8 billion at March 31, 2010, compared to $7.0 billion at the end of the previous quarter reflecting the Freddie Mac buybacks in March 2010. The portfolio’s weighted average coupon was 4.76% for the first quarter of 2010, compared to 4.88% for the fourth quarter of 2009, primarily reflecting lower reinvestment rates on new security purchases. The annualized yield on average assets declined to 4.10% for the first quarter of 2010, compared to 4.43% for the fourth quarter of 2009, primarily as a result of the increased amortization expense associated with the Freddie Mac buybacks. The annualized cost of funds on average liabilities (including hedges) was 1.51% in the first quarter of 2010, compared to 1.53% in the fourth quarter of 2009.

Dividend

The Company declared dividends of $1.20 per share of common stock with respect to the quarter ended March 31, 2010, which equaled the $1.20 per share dividend for the quarter ended December 31, 2009. Using the closing share price of $25.77 on March 31, 2010, the first quarter dividend equates to an annualized dividend yield of 18.6%.

Portfolio

The $6.8 billion portfolio of agency securities at March 31, 2010 consisted of 37.4% hybrid ARMs with 36 or fewer months to reset, 49.4% hybrid ARMs with 37 to 60 months to reset, 13.0% hybrid ARMs with 61 to 84 months to reset, and 0.2% hybrid ARMs with 85 to 120 months to reset. Of the Company’s total portfolio, 72.7% are supported by Fannie Mae and 27.3% are supported by Freddie Mac. At March 31, 2010, the weighted-average term to the next interest rate reset date was approximately 44 months, not adjusting for repayments.

During the first quarter of 2010, the expense of amortizing the premium on the Company’s securities was $9.2 million, compared to $6.2 million during the fourth quarter of 2009, reflecting the faster principal prepayments as a result of the Freddie Mac buybacks. The weighted-average principal repayment rate (scheduled and unscheduled principal payments as a percentage of the weighted-average portfolio, on an annual basis) during the first quarter of 2010 was 36.04%, compared to 22.7% during the fourth quarter of 2009, reflecting some continued seasoning of the Company’s portfolio in addition to the effect of the Freddie Mac buybacks.

Portfolio Financing and Leverage

At March 31, 2010, the Company had financed its portfolio with approximately $6.1 billion of borrowings under repurchase agreements bearing fixed interest rates until maturity. The Company’s repo debt-to-shareholders’ equity ratio at March 31, 2010, was 6.6 to 1. The Company’s repurchase agreements had a weighted-average term of approximately 42 days. Of the total repo borrowings, $400.0 million were longer term, with an average term of eight months. The Company also uses interest rate swap agreements to synthetically extend the fixed interest period of these liabilities and hedge against the interest rate risk associated with financing the Company’s portfolio. As of March 31, 2010, the Company had entered into interest rate swaps with a notional amount of $3.1 billion. The swap agreements, which are indexed to 30-day LIBOR, have an average remaining term of 28 months at an average fixed rate of 2.65%.

Book Value

The Company’s book value (shareholders’ equity) per share on March 31, 2010 was $25.48, down $0.26, or 1.01%, from the per share book value of $25.74 on December 31, 2009. The decrease in book value during the quarter represents the combination of an increase in the value of the Company’s existing agency securities, a decrease in the value of its interest rate swap positions, and the accelerated prepayments from the Freddie Mac delinquent loan buybacks.

Fannie Mae and Freddie Mac Delinquent Repurchase Activity

Earlier this year, Freddie Mac and Fannie Mae announced that they would be purchasing seriously delinquent mortgage loans out of securities that they currently guarantee. The impetus to this change was the recent adoption of new accounting standards which made the buyout of these loans a more favorable option than continuing to service their guarantees. The loans which they consider seriously delinquent are those loans that are more than 120 days past due.

Freddie Mac announced that its repurchase of these loans would result in principal payments being passed through to the mortgage-backed security holders on March 15, 2010 and April 15, 2010. The Company estimates that approximately $170 million of loans were repurchased by Freddie Mac from the Company’s mortgage-backed securities as a result of this program during the first quarter of 2010.

Fannie Mae announced that it will begin to repurchase delinquent loans in March 2010. Fannie Mae plans to conduct the repurchases over several months and to time the repurchases according to coupon rate, from highest to lowest over that period.
