For Immediate Release

WINSTON-SALEM, N.C. – (BUSINESS WIRE) – Hatteras Financial Corp. (NYSE: HTS) (the “Company”) today announced financial results for the quarter ended September 30, 2010.

Third Quarter 2010 Highlights

• Net income of $1.12 per weighted average share

• Net return on average equity of 17.26%

• Declared a $1.10 per share dividend

• Average net interest spread of 2.17%

• Quarter end book value per share of $25.83

• Annualized total expense ratio of 1.38% of average equity

• Raised $206 million in September common stock offering

Third Quarter 2010 Results

During the quarter ended September 30, 2010, the Company earned $1.12 per common share on net income of $43.2 million, of which $6.7 million was from gains on the sale of securities, compared to $1.01 per common share on net income of $36.8 million during the quarter ended June 30, 2010 with no gains from sales of securities. Net interest income for the quarter ended September 30, 2010 was $40.0 million, compared to $40.1 million for the quarter ended June 30, 2010. The Company’s average earning assets increased to $6.9 billion for the third quarter of 2010 from $6.6 billion in the previous quarter, and the yield for the third quarter of 2010 was 3.70%, falling from 3.85% in the previous quarter. The decrease in the Company’s yield was primarily a result of the lower yields on recently purchased securities. The Company’s average repurchase agreement rate was relatively flat in the third quarter of 2010 compared to the previous quarter, and at September 30, 2010, was 0.28% on all outstanding short-term (less than 30 days) repurchase agreement positions. Operating expenses were $3.5 million for the third quarter of 2010 versus $3.3 million for the second quarter of 2010. This equates to an annualized expense ratio of 1.38% of shareholders’ equity based on average equity for the quarter ended September 30, 2010.

“The third quarter was a very productive one for Hatteras as we again positioned ourselves for accretive growth. With our latest capital raise at a premium to book value we were able to acquire attractive new securities, both at market and for forward settlement and thereby improve our long-term performance outlook,” said Michael R. Hough, the Company’s Chief Executive Officer. “The bond market has been pricing in significant additional action from the Federal

Reserve driving U.S. Treasury interest rates lower. We are fortunate to have purchased a significant amount of mortgage-backed securities prior to the most recent downturn in yields and to have had a great opportunity to lock in hedges. We believe that while rates are low, the long-term spread available to us is still strong, which was the driver of our recent capital raise. At quarter-end, our debt to equity leverage ratio was 5.6:1 as a result of the new capital. Since most of our settlements will occur during the fourth quarter, we expect our leverage ratio to be closer to 7:1 by the end of December.”

Dividend

The Company declared a dividend of $1.10 per share of common stock with respect to the quarter ended September 30, 2010, which was equal to the dividend for the quarter ended June 30, 2010. Using the closing share price of $28.47 on September 30, 2010, this quarterly dividend equates to an annualized dividend yield of 15.5%.

Common Stock Offering

On September 24, 2010, the Company completed a public offering of shares of common stock. The Company sold 7,475,000 shares of common stock, including 975,000 shares pursuant to the underwriters’ overallotment option, at a price to the public of $28.75 per share, for net proceeds after underwriting discounts and expenses, of $205.6 million. The offering was completed at a premium to both book value and paid-in-capital per share.

Portfolio

At September 30, 2010, the Company owned $7.4 billion face value of Fannie Mae and Freddie Mac guaranteed mortgage securities (agency securities) with a fair market value of $7.6 billion, of which approximately 68.5% were supported by Fannie Mae and 31.5% were supported by Freddie Mac. The Company’s weighted average cost basis in these securities was $101.75 per $100 of face value. At September 30, 2010, the portfolio consisted of 9.1% adjustable rate mortgages (ARMs) with 18 or fewer months to reset, 24.9% ARMs with 19 to 36 months to reset, 58.2% ARMs with 37 to 60 months to reset, 7.6% ARMs with 61 to 84 months to reset, and 0.2% 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 51 months, not adjusting for repayments. The portfolio’s weighted average coupon was 4.29% for the third quarter of 2010, compared to 4.56% for the second quarter of 2010, reflecting the lower investment rates on new security purchases.

During the third quarter of 2010, the expense of amortizing the premium on the Company’s securities was $9.7 million, compared to $11.3 million during the second quarter of 2010, reflecting the return to more normal principal prepayment speeds as the effects of the Fannie Mae and Freddie Mac buyback programs seemed largely to come to an end in July 2010. 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 third quarter of 2010 was 33.91%, compared to 45.08% during the second quarter of 2010. This principal repayment rate reflects increased refinancing activity of consumers and the lingering effect of the Fannie Mae and Freddie Mac buybacks.

At September 30, 2010, the Company had forward purchase commitments to buy agency securities of $2.0 billion representing $1.9 billion face value of ARMs with a weighted average coupon of 3.24%.

Portfolio Financing and Leverage

At September 30, 2010, the Company had financed its portfolio with approximately $6.7 billion of borrowings under repurchase agreements bearing fixed interest rates until maturity. The annualized cost of funds on average liabilities (including swap hedges) was 1.53% in the third quarter of 2010, compared to 1.55% in the second quarter of 2010. The Company’s debt-to-shareholders’ equity ratio at September 30, 2010, was 5.6 to 1, which is below the Company’s target range and reflects the additional equity capital received near the end of the quarter. Of the total repurchase agreement borrowings, $300.0 million were longer term, with an average remaining term of six 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 September 30, 2010, the Company had entered into interest rate swaps with a notional amount of $4.2 billion. The swap agreements, which are indexed to 30-day LIBOR, have an average remaining term of 34 months at an average fixed rate of 2.33%.

Book Value

The Company’s book value (shareholders’ equity) per share on September 30, 2010 was $25.83, which was equal to the per share book value on June 30, 2010. The issuance of shares during the quarter had several effects on book value, the largest of which was the accretion to the paid-in-capital per share, raising it to $22.63 per share for the third quarter of 2010 from $21.50 per share for the second quarter of 2010, a 5.3% increase. Long term interest rates fell during the third quarter, thereby decreasing the value of the Company’s interest rate swaps. This decrease was offset by the increase in the values of the Company’s agency securities, resulting in a relatively stable value throughout the quarter. On a per share basis, the book value at September 30, 2010 consisted of $22.63 of common equity, ($0.07) of retained earnings, $5.66 of unrealized gains on agency securities, and ($2.39) of unrealized losses on interest rate swaps.
