      Annaly Mortgage Management, Inc. Announces 2nd Quarter 2004 Earnings

     NEW YORK--(BUSINESS WIRE)--July 23, 2004--Annaly Mortgage Management, Inc.
(NYSE: NLY) today reported net income for the quarter ended June 30, 2004 of
$63,835,000 or $0.52 basic earnings per common share, as compared to $58,152,000
or $0.62 basic earnings per common share for the quarter ended June 30, 2003 and
$58,843,000 or $0.52 basic earnings per common share for the quarter ended March
31, 2004.
     The Company was able to provide an annualized return on average equity of
15.76% for the quarter ended June 30, 2004, as compared to 20.79% for the
quarter ended June 30, 2003 and 16.59% for the quarter ended March 31, 2004.
Dividends declared for the quarter ended June 30, 2004 were $0.48 per share, as
compared to $0.60 per share for the quarter ended June 30, 2003 and $0.50 for
the quarter ended March 31, 2004. The annualized dividend yield for the quarter,
based on the June 30, 2004 closing price of $16.96, was 11.32%.
     Michael A.J. Farrell, Chairman, Chief Executive Officer and President of
Annaly, said, "The second quarter started with a surprisingly strong employment
report and ended with the first rate hike in four years. In between, the bond
market suffered some of its worst returns since 1980. In addition, investors in
mortgage-backed securities saw a peaking in amortization expense related to the
mini refinancing boom of the first quarter--a sequential quarterly increase of
35.2% in our case. Even with this background, I am pleased with our performance
in the quarter, as our investment strategy has delivered solid results. We are
likely to see more volatility in the bond market going forward as the Federal
Reserve changes from its accommodative monetary policy stance, but investors in
our strategy should see the benefits of improving mortgage market fundamentals,
particularly the decline in refinancing activity."
     For the quarter ended June 30, 2004, the yield on average earning assets
was 2.94% and the cost of funds on the average repurchase balance was 1.40%,
which equates to an interest rate spread of 1.54%. This is a 29 basis point
increase over the 1.25% interest rate spread for the quarter ended June 30, 2003
and a 14 basis point decrease over the 1.68% interest rate spread for the
quarter ended March 31, 2004. For the quarter ended June 30, 2004, the Company's
gain on sale of Mortgage-Backed Securities was $2.1 million as compared to $20.2
million for the quarter ended June 30, 2003 and $595,000 for the quarter ended
March 31, 2004.
     General and administrative expenses as a percentage of average assets were
0.13%, 0.12%, and 0.15% for the quarters ended June 30, 2004, June 30, 2003, and
March 31, 2004, respectively. In addition, the Company's dividend efficiency
ratio, calculated as general and administrative expenses divided by dividends
declared, was 9.5%, 7.4% and 9.8% for the quarters ended June 30, 2004, June 30,
2003, and March 31, 2004, respectively.
     The Constant Prepayment Rate was 33% during the second quarter of 2004, as
compared to 44% during the second quarter of 2003, and 31% during the first
quarter of 2004. The weighted average purchase price of the portfolio was 102.4
at June 30, 2004, 102.5 at June 30, 2003 and 102.5 at March 31, 2004. The net
amortization of premiums and accretion of discounts on investment securities for
the quarters ended June 30, 2004, June 30, 2003, and March 31, 2004 was $56.1
million, $57.6 million, and $41.5 million, respectively. Leverage at June 30,
2004 was 9.9:1, in comparison to 10.5:1 at June 30, 2003 and 8.7:1 at March 31,
2004.
     "During the quarter, the yield on the 2-year Treasury rose 111 basis
points, from 1.57% to 2.68%, and the 10-year Treasury rose 75 basis points, from
3.83% to 4.58%," said Wellington Denahan-Norris, Vice Chairman and Chief
Investment Officer of Annaly. "Our investment discipline not only served us well
during this significant market move, but it also should provide us with the
foundation to take advantage of opportunities going forward. Our portfolio is
designed to perform in a wide range of interest rate environments. For example,
in a rising rate environment, asset yields should be helped by declining
amortization expense as well as the adjustable-rate feature of approximately 70%
of our portfolio. In addition, principal amortization and new capital can be
reinvested into the higher interest rate environment."
     At June 30, 2004, June 30, 2003, and March 31, 2004, the Company had a
common stock book value of $12.07, $12.35, and $13.45, 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 30% of the Company's portfolio at June 30,
2004. The balance of the portfolio was comprised of 58% 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 June 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.
     The merger of Fixed Income Discount Advisory Company ("FIDAC"), as approved
by the shareholders on May 27, 2004, was completed on June 4, 2004. Annaly
issued 2,201,080 shares, based on the December 31, 2003 closing price of $18.40.
As was previously disclosed, following completion of the transaction Annaly will
continue to operate as a self-managed and self-advised real estate investment
trust, and FIDAC will operate 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 June 30, 2004, FIDAC
had under management approximately $1.7 billion in net assets and $12.8 billion
in gross assets, compared to $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 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 120,348,768 shares of common stock
outstanding.
