 Annaly Mortgage Management, Inc. Announces 2nd Quarter 2005 Earnings

    NEW YORK--(BUSINESS WIRE)--July 26, 2005--Annaly Mortgage
Management, Inc. (NYSE: NLY) today reported net income for the quarter
ended June 30, 2005 of $47.0 million, or $0.36 basic net income per
share available to common shareholders, as compared to $63.8 million
or $0.52 basic net income per share available to common shareholders
for the quarter ended June 30, 2004 and $59.3 million, or $0.46 basic
net income per share available to common shareholders for the quarter
ended March 31, 2005.
    The Company was able to provide an annualized return on average
equity of 11.36% for the quarter ended June 30, 2005, as compared to
15.76% for the quarter ended June 30, 2004 and 14.34% for the quarter
ended March 31, 2005. Common dividends declared for the quarter ended
June 30, 2005 were $0.36 per share, as compared to $0.48 per share for
the quarter ended June 30, 2004 and $0.45 per share for the quarter
ended March 31, 2005. The annualized dividend yield on common stock
for the quarter, based on the June 30, 2005 closing price of $17.93,
was 8.03%.
    "The short term results of Annaly reflect the persistence of
current market conditions," said Michael A.J. Farrell, Chairman, Chief
Executive Officer and President of the Company. "Financial
institutions of all stripes are finding their performances affected by
the steady drumbeat of Federal Reserve rate increases coupled with
long-term interest rates remaining in a narrow and low trading range.
As legacy portfolios and investment strategies adapt to the lower
profit potential in this environment, the return expectations of
investors have been managed accordingly. Nevertheless, our company
continues to deliver competitive results. We are excited about
opportunities for new capital in our strategy, and our success in
growing assets under management at FIDAC, our registered investment
advisor subsidiary, is a testament to the market's understanding that
the opportunities for new capital in our strategy are compelling."
    For the quarter ended June 30, 2005, the annualized yield on
average earning assets was 3.63% and the annualized cost of funds on
the average repurchase balance was 3.03%, which equates to an interest
rate spread of 0.60%. This is a 94 basis point decrease over the 1.54%
annualized interest rate spread for the quarter ended June 30, 2004
and a 58 basis point decrease over the 1.18% annualized interest rate
spread for the quarter ended March 31, 2005. For the quarter ended
June 30, 2004, the annualized yield on average earning assets was
2.94% and the annualized cost of funds on the average repurchase
balance was 1.40%. For the quarter ended March 31, 2005, the
annualized yield on average earning assets was 3.75% and the
annualized cost of funds on the average repurchase balance was 2.57%.
At June 30, 2005, the annualized yield on earning assets was 3.78% and
the annualized cost of funds on the repurchase balance was 3.20%,
which equates to an interest rate spread of 0.58%.
    For the quarters ended June 30, 2005, June 30, 2004, and March 31,
2005, the Company's gain on sale of Mortgage-Backed Securities was
$11.4 million, $2.1 million, and $580,000, respectively .
    The Constant Prepayment Rate was 27% during the second quarter of
2005, as compared to 33% during the second quarter of 2004, and 25%
during the first quarter of 2005. The weighted average purchase price
of the Company's portfolio was 102.2 at June 30, 2005, 102.4 at June
30, 2004 and 102.3 at March 31, 2005. The net amortization of premiums
and accretion of discounts on investment securities for the quarters
ended June 30, 2005, June 30, 2004, and March 31 2005 was $42.7
million, $56.1 million, and $36.1 million, respectively. The total net
unamortized premium at June 30, 2005, June 30, 2004, and December 31,
2004 was $401.4 million, $384.7 million, and $416.5 million,
respectively. Leverage at June 30, 2005 was 10.1:1, in comparison to
9.9:1 at June 30, 2004 and 10.8:1 at March 31, 2005.
    "Our team has done a fine job through this challenging
environment," said Wellington Denahan-Norris, Vice Chairman and Chief
Investment Officer of Annaly. "Our net interest spread narrowed in the
quarter as a portion of our repurchase agreements rolled into the new
interest rate environment and higher amortization expense lowered
yields. We continue to manage the portfolio to perform in a wide range
of interest rate environments, including the one we are in, by
executing our barbell strategy of maintaining a mix of fixed-rate and
adjustable- and floating-rate mortgage-backed securities. In this
strategy, there will be short-term volatility in results as the
portfolio adapts to changing market conditions, but over the long-term
this process of adapting--through coupons resetting, reinvestment of
principal and harvesting of gains--is designed to provide returns that
are competitive."
    General and administrative expenses as a percentage of average
assets were 0.14%, 0.13%, and 0.14% for the quarters ended June 30,
2005, June 30, 2004, and March 31, 2005, respectively. In addition,
the Company's Dividend Efficiency Ratio, calculated as general and
administrative expenses divided by dividends paid, was 14.2%, 9.8%,
and 11.4% for the quarters ended June 30, 2005, June 30, 2004, and
March 31, 2005, respectively.
    At June 30, 2005, June 30, 2004, and March 31, 2005, the Company
had a common stock book value per share of $12.43, $12.07, and $11.81,
respectively. The Company classifies all investment securities as
"available for sale," thus requiring the Company to record the entire
portfolio at market value. Fixed rate securities comprised
approximately 33% of the Company's portfolio at June 30, 2005. The
balance of the portfolio was comprised of 63% adjustable rate
mortgages and 4% LIBOR floating rate collateralized mortgage
obligations. The Company has continued to avoid the introduction of
credit risk into its portfolio. As of June 30, 2005, all of the assets
in the Company's portfolio were FNMA, GNMA, FHLMC mortgage-backed
securities, and agency debentures, which carry an actual or implied
"AAA" rating.
    At June 30, 2005, FIDAC, Annaly's wholly-owned registered
investment advisor, had under management approximately $3.1 billion in
net assets and $27.8 billion in gross assets, as compared to $2.3
billion in net assets and $18.6 billion in gross assets at March 31,
2005 and $1.9 billion in net assets and $15.9 billion in gross assets
at December 31, 2004. For the quarter ended June 30 2005, FIDAC earned
investment advisory and service fees, net of fees paid to
distributors, of $7.5 million, as compared to $4.7 million for the
quarter ended March 31, 2005. FIDAC, organized as a taxable REIT
subsidiary of Annaly, generally receives net investment advisory fees
of approximately 10 to 20 basis points of the gross assets it manages,
assists in managing or supervises.
    "With strong momentum in the second quarter, FIDAC's net and gross
assets under management have grown since year-end 2004 by 63% and 75%,
respectively," said Mr. Farrell. "Growth has come in both existing
funds and new funds, as we continue to work to deliver high current
income using high credit-quality assets. This investment proposition
is finding acceptance with investors in the US and around the world,
and we believe we are well-positioned to continue to grow our asset
management business."
    Annaly manages assets on behalf of institutional and individual
investors worldwide through Annaly and through the funds managed by
its wholly-owned registered investment advisor, FIDAC. The Company's
principal business objective is to generate net income for
distribution to investors from the spread between the interest income
on its mortgage-backed securities and the cost of borrowing to finance
their acquisition and from dividends Annaly receives from FIDAC, which
earns investment advisory fee income. The Company, a Maryland
corporation that has elected to be taxed as a real estate investment
trust ("REIT"), currently has 122,554,831 shares of common stock
outstanding.
