                   Annaly Mortgage Management, Inc.
           Announces 4th Quarter and Year End 2003 Earnings

    NEW YORK--(BUSINESS WIRE)--Feb. 6, 2004--Annaly Mortgage
Management, Inc. (NYSE: NLY) today reported earnings for the quarter
ended December 31, 2003 of $42,697,000 or $0.44 per average share
outstanding, as compared to $50,426,000 or $0.60 per average share
outstanding for the quarter ended December 31, 2002. Earnings for the
year ended December 31, 2003 were $180,103,000 or $1.95 per average
share outstanding, as compared to $219,407,000 or $2.68 per average
share outstanding for the year ended December 31, 2002.
    The Company was able to provide an annualized return on average
equity of 14.88% for the quarter ended December 31, 2003, as compared
to 18.63% for the quarter ended December 31, 2002. The return on
average equity for the year ended December 31, 2003 was 16.04%, as
compared to 22.44% for the previous year. Dividends declared for the
quarter ended December 31, 2003 were $0.47 per share, compared to
$0.28 for the quarter ended September 30, 2003 and $0.68 per share for
the quarter ended December 31, 2002. Dividends declared for 2003 were
$1.95, compared to $2.67 for 2002. The annualized dividend yield for
the quarter, based on the December 31, 2003 closing price of $18.40,
was 10.22%.
    "The improving fundamentals in the mortgage market--most notably
the substantial reduction in prepayment speeds and premium
amortization--enabled us to increase fourth quarter earnings per share
by 47% and net interest income by 105% over the prior quarter," said
Michael A.J. Farrell, Chairman, Chief Executive Officer and President
of Annaly Mortgage Management. "The return to more hospitable
operating conditions notwithstanding, the macroeconomic picture
remains cloudy, nominal interest rates are at generational lows and
refinancing activity, while down substantially from last spring and
summer, is still at historically high levels. We remain vigilant for
continued volatility in the markets."
    For the quarter ended December 31, 2003, the yield on average
earning assets was 3.02% and the cost of funds on the average
repurchase balance was 1.50%, which equates to an interest rate spread
of 1.52%. This is an 83 basis point increase over the 0.69% interest
rate spread for the quarter ended September 30, 2003, and a 6 basis
point decrease over the 1.58% interest rate spread for the quarter
ended December 31, 2002. For the quarter ended September 30, 2003, the
yield on average earning assets was 2.13% and the cost of funds on the
average repurchase balance was 1.44%, and for the quarter ended
December 31, 2002 the yield on average earning assets was 3.56% and
the cost of funds on the average repurchase balance was 1.98%. For the
year ended December 31, 2003, the yield on average earning assets was
2.81% and the cost of funds on the average repurchase balance was
1.58%. For the year ended December 31, 2002, the yield on average
earning assets was 4.22% and the cost of funds on the average
repurchase balance was 2.10%. The interest rate spread decreased 89
basis points to 1.23% in 2003 from 2.12% for the prior year.
    The Constant Prepayment Rate decreased to 37% during the quarter
ended December 31, 2003, as compared to 48% in the third quarter of
2003 and 43% for the quarter ended December 31, 2002. The Constant
Prepayment Rate increased to 42% for the year ended December 31, 2003,
as compared to 33% for the year ended December 31, 2002. The
homeowners' prepayment option makes the average term, yield and
performance of a mortgage-backed security uncertain because of the
uncertainty in timing the return of principal. In general, an increase
in amortization will decrease the total yield on a bond purchased at a
premium, because over the life of the bond that premium has to be
amortized. Conversely, a decrease in amortization will increase the
total yield on a bond purchased at a premium. The total amount of
amortization for the quarters ended December 31, 2003, September 30,
2003, and December 31, 2002 were $38,390,000, $72,047,000, and
$40,281,000, respectively. The total amortization for the year ended
December 31, 2003 was $216,570,000 and for the year ended December 31,
2002 was $106,198,000. The weighted average purchase price of the
portfolio was 102.5 at December 31, 2003, 102.6 at September 30, 2003,
and 102.6 at December 31, 2002. Leverage at December 31, 2003 was
9.6:1, in comparison to 9.8:1 at September 30, 2003 and 9.4:1 at
December 31, 2002.
    Commenting on the portfolio, Wellington Denahan, Vice Chairman and
Chief Investment Officer, said, "The MBS market has begun to reflect
the changing mortgage landscape. The decline in refinancing activity
has moderated the effect of prepayments on the portfolio, resulting in
improved yields. The CPR fell 11 percentage points from the third
quarter to the fourth quarter, while the average yield on securities
rose 89 basis points. We have also seen better investment
opportunities due to the change in market fundamentals. Going forward,
further declines in CPR will continue to help yields, but the low
nominal level of rates will remain an issue."
    For the quarter ended December 31, 2003, the Company did not
realize gains, as compared to $9.7 million in gains for the quarter
ended September 30, 2003 and $11.6 million in gains for the quarter
ended December 31, 2002. For the year ended December 31, 2003, the
Company's gain on sale of assets was $40.9 million as compared to the
prior year of $21.1 million.
    General and administrative expenses, as a percent of average
assets was 0.13% for the quarter ended December 31, 2003, 0.12% for
the quarter ended September 30, 2003 and 0.13% for the quarter ended
December 31, 2002. General and administrative expenses, as a percent
of average assets was 0.13% for the years ended December 31, 2003 and
2002. In addition, the Company's Dividend Efficiency Ratio, calculated
as general and administrative expenses divided by dividends paid, was
9.4%, 15.3% and 6.8% for the quarters ended December 31, 2003,
September 30, 2003, and December 31, 2002, respectively.
    "With our low expense ratio," said Mr. Farrell, "the increase in
asset yield that comes about from slower prepayment speeds essentially
drops to the bottom line. Our exercise of prudent portfolio management
during the challenges of 2003 has left us well-positioned to take
advantage of investment opportunities going forward."
    At December 31, 2003, September 30, 2003 and December 31, 2002,
respectively, the Company had a book value of $11.96, $11.94 and
$12.77. The Company classifies all investment securities as "available
for sale;" which requires the Company to record the entire portfolio
at market value. Fixed rate securities comprised approximately 27% of
the Company's portfolio at December 31, 2003. The balance of the
portfolio was comprised of 56% adjustable rate mortgages and 17% LIBOR
floating rate collateralized mortgage obligations. The Company has
continued to avoid the introduction of credit risk into its portfolio.
As of December 31, 2003, 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.
    Subsequent to year end, the Company announced that it signed a
definitive merger agreement to acquire Fixed Income Discount Advisory
Company upon shareholder approval, and the Company raised
approximately $363.5 million in net proceeds through a follow-on
offering of 20,700,000 shares of common stock.
    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 116,803,031 shares of
common stock outstanding.
