Annaly Mortgage Management, Inc. Announces 1st Quarter 2004 Earnings

    NEW YORK--(BUSINESS WIRE)--April 26, 2004--Annaly Mortgage
Management, Inc. (NYSE: NLY) today reported earnings for the quarter
ended March 31, 2004 of $58,843,000 or $0.52 basic earnings per share,
as compared to $50,775,000 or $0.60 earnings per share for the quarter
ended March 31, 2003 and $42,697,000 or $0.44 per average share
outstanding for the quarter ended December 31, 2003.
    The Company was able to provide an annualized return on average
equity of 16.59% for the quarter ended March 31, 2004, as compared to
18.83% for the quarter ended March 31, 2003 and 14.88% for the quarter
ended December 31, 2003. Dividends declared for the quarter ended
March 31, 2004 were $0.50 per share, compared to $0.60 per share for
the quarter ended March 31, 2003 and $0.47 for the quarter ended
December 31, 2003. The annualized dividend yield for the quarter,
based on the March 31, 2004 closing price of $19.55, was 10.23%.
    Michael A.J. Farrell, Chairman, Chief Executive Officer and
President of Annaly, said, "We are pleased with our solid performance
in the first quarter as the portfolio benefited from slower prepayment
speeds and an improved spread between the yield on our assets and the
cost to finance them. Interest rates fell in the period, which
resulted in a corresponding increase in the Mortgage Bankers
Association Refinancing Index as homeowners took advantage of cheaper
financing opportunities. While the effects of this pickup in
refinancing activity will be felt in the portfolio during the second
quarter, the recent backup in rates should lead to positive
fundamentals thereafter."
    For the quarter ended March 31, 2004, the yield on average earning
assets was 3.16% and the cost of funds on the average repurchase
balance was 1.48%, which equates to an interest rate spread of 1.68%.
This is a 13 basis point increase over the 1.55% interest rate spread
for the quarter ended March 31, 2003 and a 16 basis point increase
over the 1.52% interest rate spread for the quarter ended December 31,
2003. For the quarter ended March 31, 2004, the Company's gain on sale
of a Mortgage-Backed Securities was $595,000 as compared to $11.0
million for the quarter ended March 31, 2003 and zero gains in the
prior quarter.
    General and administrative expenses, as a percentage of average
assets were 0.15%, 0.12%, and 0.13% for the quarters ended March 31,
2004, March 31, 2003, and December 31, 2003, respectively. In
addition, the Company's Dividend Efficiency Ratio, calculated as
general and administrative expenses divided by dividends declared, was
9.8%, 7.3% and 9.4% for the quarters ended March 31, 2004, March 31,
2003, and December 31, 2003, respectively.
    The Constant Prepayment Rate decreased to 31% during the first
quarter of 2004, as compared to 41% during the first quarter of 2003,
and 37% during the fourth quarter of 2003. The weighted average
purchase price of the portfolio was 102.5 at March 31, 2004, 102.6 at
March 31, 2003 and 102.5 at December 31, 2003. The total amount of
amortization for the quarters ended March 31, 2004, March 31, 2003,
and December 31, 2003 was $41,501,000, $48,519,000, and $38,390,000,
respectively. Leverage at March 31, 2004 was 8.7:1, in comparison to
9.5:1 at March 31, 2003 and 9.6:1 at December 31, 2003.
    At March 31, 2004, March 31, 2003, and December 31, 2003, the
Company had a common stock book value of $13.45, $12.72, and $11.96,
respectively. The Company classifies all investment securities as
"available for sale," therefore requiring the Company to record the
entire portfolio at market value. Fixed rate securities comprised
approximately 26% of the Company's portfolio at March 31, 2004. The
balance of the portfolio was comprised of 62% adjustable rate
mortgages and 12% LIBOR floating rate collateralized mortgage
obligations. The Company has continued to avoid the introduction of
credit risk into its portfolio. As of March 31, 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.
    "Our portfolio composition and our leverage ratio reflect a number
of market realities," said Wellington Denahan, Annaly's Vice Chairman
and Chief Investment Officer. "Bonds continue to be volatile and
despite the recent backup interest rates are still near historical
lows. With this backdrop, we believe our prudence and our strong
capital base leave us well-positioned to take advantage of future
opportunities. Our investment philosophy has always been to manage the
portfolio for the long-term--to generate a consistent dividend stream
for shareholders over time."
    During the quarter ended March 31, 2004, the Company (i) announced
that it signed a definitive agreement to acquire Fixed Income Discount
Advisory Company upon shareholder approval; (ii) raised approximately
$363.5 million in net proceeds through a follow-on offering of
20,700,000 shares of common stock; and (iii) raised approximately
$102.9 million in net proceeds through an offering of 4,250,000 shares
of 7.875% Series A Cumulative Redeemable Preferred Stock.
    "The path to growth for a REIT is paved with accretive, sequential
capital raises,"said Mr. Farrell. "The success of our offerings this
quarter has been an affirmation by the market of the strength of our
business model and the consistency of our track record, through a wide
range of interest rate environments."
    The Company is a Maryland corporation which owns and manages a
portfolio of mortgage-backed securities. The Company's principal
business objective is to generate net income for distribution to
stockholders from the spread between the interest income on its
mortgage-backed securities and the cost of borrowing to finance their
acquisition. The Company has elected to be taxed as a real estate
investment trust ("REIT") and currently has 117,884,862 shares of
common stock outstanding.
    The Company will hold the first quarter 2004 earnings conference
