FOR IMMEDIATE RELEASE

      ANNALY MORTGAGE MANAGEMENT, INC. ANNOUNCES 3rd QUARTER 2003 EARNINGS

New York, New York -October 21, 2003 - Annaly Mortgage Management, Inc. (NYSE:
NLY) today reported earnings for the quarter ended September 30, 2003 of
$28,479,000 or $0.30 per average share outstanding, as compared to $56,668,000
or $0.68 per average share outstanding for the quarter ended September 30, 2002.

The Company was able to provide an annualized return on average equity of 9.88%
for the quarter ended September 30, 2003, as compared to 20.79% for the quarter
ended June 30, 2003, and 21.24% for the quarter ended September 30, 2002.
Dividends declared for the quarter ended September 30, 2003 were $0.28 per
share, compared to $0.60 for the quarter ended June 30, 2003 and $0.68 per share
for the quarter ended September 30, 2002. The annualized dividend yield for the
quarter, based on the September 30, 2003 closing price of $16.42, was 6.82%.

"Our third quarter results reflect the transition from a period of very low
interest rates and very high prepayment speeds to a period of higher rates and
slower speeds," said Michael A.J. Farrell, Chairman, Chief Executive Officer and
President of Annaly. "As we have reiterated time and again in 2002 and 2003, our
job as managers during this time has been to protect capital and remain
defensive until the fundamentals of the mortgage market improved. The good news
is that amortization expense--which has exceeded interest expense through the
first 9 months of the year--is now subsiding. Looking ahead to the fourth
quarter and beyond, we expect that the substantial reduction in prepayment
speeds and premium amortization will serve to enhance earnings."

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%,
which equates to an interest rate spread of 0.69%. This is a 56 basis point
decrease over the 1.25% interest rate spread for the quarter ended June 30,
2003, when the yield on average earning assets was 2.93% and the cost of funds
on the average repurchase balance was 1.68%, and a 128 basis point decrease over
the 1.97% interest rate spread for the quarter ended September 30, 2002, when
the yield on average earning assets was 4.10% and the cost of funds on the
average repurchase balance was 2.13%.

The Constant Prepayment Rate increased to 48% during the third quarter of 2003,
as compared to 44% in the second quarter of 2003 and 34% for the quarter ended
September 30, 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, prepayments decrease
the total yield on a bond purchased at a premium, because over the life of the
bond that premium has to be amortized. The faster prepayments, the shorter the
life of the security, which results in the increased amortization. The total
amount of amortization for the quarters ended September 30, 2003, June 30, 2003,
and September 30, 2002 were $72,047,000, $57,615,000, and $28,229,000,
respectively. The weighted average



purchase price of the portfolio was 102.6 at September 30, 2003, 102.5 at June
30, 2003, and 102.3 at September 30, 2002.

"While the bond market has shown remarkable price volatility during the quarter,
its dominant feature has been the historically fast prepayment speeds due to
refinancing activity," said Wellington Denahan, Vice Chairman and Chief
Investment Officer. "Because of the two to three month lag between mortgage
applications and their related cash flows, during the third quarter we
recognized the amortization expense related to the second quarter peak in the
MBA Refi Index. Since the peak on May 30, the MBA Refi Index has fallen
approximately 75%. Accordingly, we expect to see our amortization expense fall
beginning in the fourth quarter."

For the quarter ended September 30, 2003, the Company's gain on sale of assets
was $9.7 million as compared to $20.2 million in the quarter ended June 30, 2003
and $4.7 million for the quarter ended September 30, 2002. Leverage at September
30, 2003 was 9.8:1, in comparison to 10.5:1 at June 30, 2003 and 9.0:1 at
September 30, 2002.

General and administration expenses, as a percent of average assets was 0.12%
for the quarters ended September 30, 2003, June 30, 2003 and September 30, 2002,
respectively. In addition, the Company's Dividend Efficiency Ratio, calculated
as general and administrative expenses divided by dividends paid, was 15.3%,
7.4% and 5.7% for the quarters ended September 30, 2003, June 30, 2003, and
September 30, 2002, respectively. "In our simple, low G&A business model," said
Mr. Farrell, "the increase in net interest income that comes about from
reductions in premium amortization essentially drops to the bottom line."

At September 30, 2003, June 30, 2003, and September 30, 2002, respectively, the
Company had a book value of $11.94, $12.35 and $12.84. 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 31% of the Company's portfolio at September 30, 2003.
The balance of the portfolio was comprised of 50% adjustable rate mortgages and
19% LIBOR floating rate collateralized mortgage obligations. The Company has
continued to avoid the introduction of credit risk into its portfolio. As of
September 30, 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.

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 95,984,229 shares of common stock
outstanding.
