Annaly Mortgage Management, Inc. Announces 3rd Quarter 2004 Earnings

    NEW YORK--(BUSINESS WIRE)--Oct. 25, 2004--Annaly Mortgage
Management, Inc. (NYSE: NLY) today reported net income for the quarter
ended September 30, 2004 of $66,620,000 or $0.53 basic net income per
share available to common shareholders, as compared to $28,479,000 or
$0.30 basic net income per share available to common shareholders for
the quarter ended September 30, 2003 and $63,835,000 or $0.52 basic
net income per share available to common shareholders for the quarter
ended June 30, 2004.
    The Company was able to provide an annualized return on average
equity of 16.59% for the quarter ended September 30, 2004, as compared
to 9.88% for the quarter ended September 30, 2003 and 15.76% for the
quarter ended June 30, 2004. Dividends declared for the quarter ended
September 30, 2004 were $0.50 per share, as compared to $0.28 per
share for the quarter ended September 30, 2003 and $0.48 for the
quarter ended June 30, 2004. The annualized dividend yield for the
quarter, based on the September 30, 2004 closing price of $17.13, was
11.68%.
    Michael A.J. Farrell, Chairman, Chief Executive Officer and
President of Annaly, said, "While I am pleased with the performance
delivered by our team in this particularly challenging quarter, I want
to reiterate that it is our long-term approach to management that
rewards our investors. Careful observers of our track record of
delivering consistently strong returns understand that what
differentiates us from other participants in the market place is the
resiliency of our barbell strategy, our non-correlation with mortgage
origination cycles and our industry-low cost structure. Furthermore,
the recent addition of our growing asset management business has been
immediately accretive to shareholders, adds a smoothing, tax-efficient
component to our earnings stream and will serve to further set us
apart going forward as we continue to operate in this volatile, low
interest rate market."
    For the quarter ended September 30, 2004, the yield on average
earning assets was 3.36% and the cost of funds on the average
repurchase balance was 1.80%, which equates to an interest rate spread
of 1.56%. This is an 87 basis point increase over the 0.69% interest
rate spread for the quarter ended September 30, 2003 and a 2 basis
point increase over the 1.54% interest rate spread for the quarter
ended June 30, 2004. For the quarter ended September 30, 2004, the
Company's gain on sale of Mortgage-Backed Securities was $1.4 million
as compared to $9.7 million for the quarter ended September 30, 2003
and $2.1 million for the quarter ended June 30, 2004.
    General and administrative expenses as a percentage of average
assets were 0.14%, 0.12%, and 0.13% for the quarters ended September
30, 2004, September 30, 2003, and June 30, 2004, respectively. In
addition, the Company's dividend efficiency ratio, calculated as
general and administrative expenses divided by dividends declared, was
9.8%, 15.3% and 9.5% for the quarters ended September 30, 2004,
September 30, 2003, and June 30, 2004, respectively.
    The Constant Prepayment Rate was 25% during the third quarter of
2004, as compared to 48% during the third quarter of 2003, and 33%
during the second quarter of 2004. The weighted average purchase price
of the portfolio was 102.4 at September 30, 2004, 102.6 at September
30, 2003 and 102.4 at June 30, 2004. The net amortization of premiums
and accretion of discounts on investment securities for the quarters
ended September 30, 2004, September 30, 2003, and June 30, 2004 was
$39.7 million, $72.0 million, and $56.1 million, respectively.
Leverage at September 30, 2004 was 9.4:1, in comparison to 9.8:1 at
September 30, 2003 and 9.9:1 at June 30, 2004.
    "In the third quarter, the Fed continued its 'measured' pace of
interest rate hikes," said Wellington Denahan-Norris, Vice Chairman
and Chief Investment Officer of Annaly, "however our interest rate
spread improved over the prior quarter since our increased cost of
financing was more than offset by the decline in amortization expense
due to slowing prepayment speeds as well as the upward resetting of
coupons on our adjustable-rate and floating-rate assets. Looking ahead
to the fourth quarter, we are likely to see prepayments increase
somewhat in response to lower mortgage rates, but our portfolio is
designed to adjust to each new interest rate scenario. While we see
the opportunity to put capital to work in these volatile markets, we
continue to be prudent in our use of leverage and in our asset
selection."
    At September 30, 2004, September 30, 2003, and June 30, 2004, the
Company had a common stock book value per share of $12.84, $11.94, and
$12.07, 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 29% of the Company's portfolio at September 30, 2004.
The balance of the portfolio was comprised of 61% adjustable rate
mortgages and 10% LIBOR floating rate collateralized mortgage
obligations. The Company has continued to avoid the introduction of
credit risk into its portfolio. As of September 30, 2004, 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.
    FIDAC operates as Annaly's wholly-owned taxable REIT subsidiary.
FIDAC is a registered investment advisor which generally receives
annual net investment advisory fees of approximately 10 to 15 basis
points of the gross assets it manages, assists in managing or
supervises. At September 30, 2004, FIDAC had under management
approximately $1.7 billion in net assets and $13.9 billion in gross
assets, compared to $1.7 billion in net assets and $12.8 billion in
gross assets at June 30, 2004 and $1.5 billion in net assets and $13.6
billion in gross assets at December 31, 2003.

    The Company is a Maryland corporation which owns and manages a

investment trust ("REIT") and currently has 121,235,702 shares of
common stock outstanding.
