Hatteras Financial Corp. Announces Second 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 June 30, 2010.

Second Quarter 2010 Highlights

• Net income of $1.01 per diluted share

• Net return on average equity of 15.63%

• Declared a $1.10 per share dividend

• Average net interest spread of 2.30%

• Quarter end book value per share of $25.83

• Annualized total expense ratio of 1.38% of shareholders’ equity

Second Quarter 2010 Results

During the quarter ended June 30, 2010, the Company earned $1.01 per diluted share on net income of $36.8 million, compared to $1.21 per diluted share on net income of $43.7 million during the quarter ended March 31, 2010. Most of the decrease in earnings arose from the effect of the delinquent loan repurchase programs at Fannie Mae and Freddie Mac. These programs, discussed below, resulted in significantly higher premium amortization in the quarter and some timing delay in the deployment of the returned principal. Some yield erosion was also due to the purchasing of new securities at lower yields than the average on the existing portfolio.

Net interest income for the quarter ended June 30, 2010 was $40.1 million, compared to $45.8 million for the quarter ended March 31, 2010. The Company’s average earning assets decreased to $6.6 billion for the second quarter of 2010 from $6.7 billion in the previous quarter, and the yield for the second quarter of 2010 was 3.85%, falling from 4.10% in the previous quarter. The decrease in the yield was primarily driven by the accelerated rate of repayments during the quarter. The Company’s average repurchase agreement (repo) rate was relatively flat in the second quarter of 2010 compared to the previous quarter, and at June 30, 2010, was 0.28% on all outstanding short-term (less than 30 days) repo positions. Operating expenses were $3.3 million for the second quarter versus $3.1 million for the first quarter of 2010. This equates to an annualized expense ratio of 1.38% of shareholders’ equity based on average equity for the quarter ended June 30, 2010.

Dividend

The Company declared a dividend of $1.10 per share of common stock with respect to the quarter ended June 30, 2010, versus $1.20 per share for the quarter ended March 31, 2010. Using the closing share price of $27.82 on June 30, 2010, this quarterly dividend equates to an annualized dividend yield of 15.8%.

“In the second quarter, Hatteras’ earnings and investment portfolio felt the full impact of Fannie Mae’s delinquent loan buybacks as they cleared most of their intended purchases affecting our portfolio by June 30^th,” said Michael R. Hough, the Company’s Chief Executive Officer. “The accelerated prepayments we experienced are just another example of why we have always focused on purchasing assets at lower premiums to par because the drivers of prepayment rate assumptions can change. Premiums in the agency MBS market continue to be large which is why we have taken our time to reinvest prepayment proceeds this quarter and lower the purchase price with up to 90 day forward settlements. As the size of the portfolio ramps back up, we are looking forward to again realizing the potential of our portfolio. We are pleased to have been able to utilize some of the excess earnings we retained last year when prepayments were unusually and unpredictably slow and to have distributed a $1.10 dividend to our shareholders. Since quarter end, interest rates have continued even lower with our focus continuing to be on mitigating the risks associated with changing rates.”

Portfolio

At June 30, 2010, the Company owned $6.5 billion face value of Fannie Mae and Freddie Mac guaranteed mortgage securities (agency securities) with a fair market value of $6.8 billion, of which approximately 71.0% were supported by Fannie Mae and 29.0% were supported by Freddie Mac. The Company’s weighted average cost basis in these securities was $101.58 per $100 of face value. At June 30, 2010, the portfolio consisted of 41.7% hybrid ARMs with 36 or fewer months to reset, 52.0% hybrid ARMs with 37 to 60 months to reset, 5.7% hybrid ARMs with 61 to 84 months to reset, and 0.6% hybrid ARMs with 85 to 120 months to reset. For the entire portfolio, the weighted-average term to the next interest rate reset date was approximately 45 months, not adjusting for repayments. The portfolio’s weighted average coupon was 4.56% for the second quarter of 2010, compared to 4.76% for the first quarter of 2010, reflecting lower reinvestment rates on new security purchases.

During the second quarter of 2010, the expense of amortizing the premium on the Company’s securities was $11.3 million, compared to $9.2 million during the first quarter of 2010, reflecting the faster principal prepayments as a result of the Fannie Mae and 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 second quarter of 2010 was 45.08%, compared to 36.04% during the first quarter of 2010, reflecting increased refinancing activity of consumers in addition to the effect of the Fannie Mae and Freddie Mac buybacks.

The Company had forward purchase commitments to buy agency securities of $850.6 million representing $830.3 million face value of hybrid arms with a weighted average coupon of 3.62%. These securities had a weighted average purchase price of $102.5 and a market value of $859.6 million at June 30, 2010.

Portfolio Financing and Leverage

At June 30, 2010, the Company had financed its portfolio with approximately $6.0 billion of borrowings under repurchase agreements bearing fixed interest rates until maturity. The annualized cost of funds on average liabilities (including swap hedges) was 1.55% in the second quarter of 2010, compared to 1.51% in the first quarter of 2010. The Company’s repo debt-to-shareholders’ equity ratio at March 31, 2010, was 6.2 to 1. Of the total repo borrowings, $300.0 million were longer term, with an average remaining term of nine 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 June 30, 2010, the Company had entered into interest rate swaps with a notional amount of $3.4 billion. The swap agreements, which are indexed to 30-day LIBOR, have an average remaining term of 29 months at an average fixed rate of 2.61%.

Book Value

The Company’s book value (shareholders’ equity) per share on June 30, 2010 was $25.83, up $0.35, or 1.4%, from the per share book value of $25.48 on March 31, 2010. The increase in book value during the quarter represents the combination of an increase in the value of the Company’s existing agency securities and a decrease in the value of its interest rate swap positions. On a per share basis, the book value at June 30, 2010 consisted of $21.50 of common equity, $0.12 of retained earnings, $6.36 of unrealized gains on agency securities, and ($2.15) of unrealized losses on interest rate swaps.

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. Fannie Mae announced that it would begin to repurchase delinquent loans in March 2010 and likely end those purchases in July 2010.
