AmNet Mortgage, Inc. Reports Second Quarter Results; Revises 2004 Guidance

    SAN DIEGO--(BUSINESS WIRE)--Aug. 16, 2004--AmNet Mortgage, Inc.
(formerly American Residential Investment Trust, Inc.) (Amex:INV), the
parent company of American Mortgage Network (AmNet), a wholesale
mortgage bank serving mortgage brokers nationwide, today reported
second quarter results, highlights of which included:

    --  Second quarter consolidated earnings were $208 thousand or
        $0.02 cents per diluted share including an after-tax charge of
        approximately $519 thousand or $0.07 cents per diluted share,
        related to expenses incurred on the sale of the majority of
        the mortgage asset portfolio;

    -- $1.4 million in pre-tax income was earned by AmNet; and

    -- $2.6 billion of mortgage loans were funded in the second
        quarter.

    Other Company highlights:


    --  Completed the sale of the majority of the mortgage
        asset portfolio with net cash proceeds of $24.9
        million;

    --  Repurchased 500,000 shares at $8.80 per share in a privately
        negotiated transaction;

    --  Cash and cash equivalents were $53.2 million as of June 30,
        2004; and

    --  Book value per outstanding share increased to $10.63.

    Consolidated Results

    For the second quarter of 2004, AmNet Mortgage, Inc. reported
consolidated net income of $208 thousand, or $0.02 cents per diluted
share including an after-tax charge of approximately $519 thousand or
$0.07 cents per diluted share, related to expenses incurred on the
sale of the majority of the mortgage asset portfolio.
    Commenting on results, John M. Robbins, Chief Executive Officer,
said, "There were a number of significant events during the second
quarter. We completed the sale of the majority of the REIT mortgage
asset portfolio. The net cash proceeds were $24.9 million and we
extinguished more than $90 million of bond collateral debt. The
Company has cash and cash equivalents of $53.2 million, while our book
value per outstanding share was $10.63 at the end of the second
quarter. We repurchased 500,000 shares of our common stock at $8.80
per share in a privately negotiated transaction, which was not part of
our previously announced stock repurchase plan."
    Robbins continued, "As expected, this quarter was marked by
intense competition and price compression indicative of a mortgage
market that has rapidly contracted. We continued to implement new
product and marketing programs and opened offices and recruited
seasoned managers in Los Angeles, San Francisco and Salt Lake City.
The resources and time required to bring new branches to maturity has
been greater than anticipated."
    The Company reports its results in two segments -- mortgage
banking (AmNet) and mortgage asset portfolio investments (AMREIT).

    Mortgage Banking Business - American Mortgage Network (AmNet)

    For the second quarter of 2004, AmNet's pre-tax income was $1.4
million, compared to a loss of $5.9 million in the first quarter of
2004. AmNet funded $2.6 billion in home loans during the second
quarter of 2004, compared to $1.9 billion in the first quarter of
2004.
    In the second quarter of 2004, gain on sales of loans, net of
derivative financial instruments, was $17.6 million, or 67 basis
points on $2.6 billion of loan sales volume. This compared to gain on
sales of loans, net of derivative financial instruments, of $8.9
million, or 54 basis points on $1.6 billion of loan sale volume, in
the first quarter of 2004.
    Interest revenue on mortgage assets in the second quarter was $9.0
million and was offset by interest expense of $4.4 million, resulting
in a net interest spread of $4.6 million, or 18 basis points on $2.6
billion of loan fundings in the second quarter of 2004. In the first
quarter of 2004, interest revenue on mortgage assets was $5.0 million
and was offset by interest expense of $2.3 million, resulting in a net
interest spread of $2.7 million, or 14 basis points on $1.9 billion of
loan fundings.
    Operating expenses, which were total expenses of $25.2 million
less interest expense of $4.4 million, were $20.8 million during the
second quarter, or 81 basis points on loan fundings. These expenses
included an estimated $6.5 million in sales commissions and other
variable expenses, representing approximately 31% of total operating
expenses. Operating expenses in the first quarter of 2004 were $17.5
million, or 94 basis points on loan fundings.
    Commenting on mortgage operations, Robbins added, "During the
second quarter, the mortgage bank had a pre-tax profit of $1.4
million. We transitioned our loan mix to higher margin products, such
as ARMs and Alt-A. In fact, Alt-A loans made up 28% of the total mix
in June versus 8% for all of the first quarter. The number of
commissioned account executives increased to 126, compared with 108 at
the end of the first quarter. Since June 30th, we have added 24 new
account executives, bringing our current total to 150."

    Mortgage Asset Portfolio Business

    During the second quarter, the sale of the majority of the
mortgage asset portfolio business was completed. Mortgage portfolio
assets declined to $19.3 million at June 30, 2004, and are expected to
have nominal earnings and cash flow impact going forward.
    For the second quarter of 2004, the mortgage asset portfolio
business incurred a pre-tax loss of $1.0 million, compared to a
pre-tax loss of $3.7 million in the first quarter of 2004. The primary
cause for the losses in both periods was related to the mortgage asset
portfolio sale. Pre-tax losses on bond collateral held for sale of
$880 thousand and $4.4 million were recorded in the second and first
quarters, respectively.
    Commenting on the benefits of the mortgage asset portfolio sale,
Judith A. Berry, Executive Vice President and Chief Financial Officer
said, "This transaction simplified the Company's balance sheet,
reduced our leverage to six to one, increased our cash balances by 79%
from the first quarter and eliminated future credit and pre-payment
risk associated with the sold portion of the portfolio."

    Liquidity and Book Value

    Cash and cash equivalents were $53.2 million as of June 30, 2004,
compared to $29.7 million at March 31, 2004. Cash per outstanding
share increased from $3.78 at March 31, 2004 to $7.20 at June 30,
2004. The Company's book value per outstanding share increased to
$10.63 at June 30, 2004, compared to $10.52 at March 31, 2004,
primarily due to share repurchases during the second quarter.

    2004 Guidance

    The Mortgage Banking Association (MBA) estimates that third and
fourth quarter 2004 originations will be down significantly--some 14%
from their April, 2004 forecast and 54% from the last two quarters of
2003. The decrease is attributable to a lower refinance market. As a
result of this overall market contraction as well as adjustments in
the number and timing of account executives that were expected to join
the Company, AmNet's 2004 loan production is expected to be between $8
billion and $9 billion. Earnings for the third and fourth quarter of
2004 are expected to be in line with second quarter results.
    Reduced earnings guidance is related to a number of factors which
include: the 14% market decline from previous MBA estimates for the
second half of the year; increased competition with resultant price
compression in certain products such as Alt-A; and a challenging
recruiting and retention environment for account executives.
    Commenting on revised guidance, Robbins noted, "To respond to
competitive pressures and slower market share growth, we have
initiated a number of cost reduction measures. We are right sizing and
workload balancing support staff to align with lower anticipated
volumes. These efforts enhance our ability to utilize our existing
infrastructure while continuing to grow our sales presence."
    Robbins concluded, "The mortgage market is undergoing a period of
extreme volatility as measured by the MBA. The MBA forecast predicts
that the market will shrink 54% from the second quarter of 2004 to the
first quarter of 2005. The MBA also expects that originations will
decrease from $848 billion to $388 billion over the period. It also
anticipates that the market will shrink some 68% from a peak of $1.2
trillion in the third quarter of 2003 to $388 billion in the first
quarter of 2005. Against this backdrop of both recent and anticipated
market contraction, the Company has added significantly to both the
number of account executives and loan production offices. Our subprime
product line will roll out across the country during the next month
and we have hired an industry leader in wholesale subprime to drive
sales nationwide. While we anticipate modest profits for the remainder
of the year, we expect to reap the future benefits of our investments
in the branch network, the recruitment of account executives, the
migration to higher margin products and enhanced technology to gain
market share."

today at 1:30 p.m. Pacific/4:30 p.m. Eastern to discuss second quarter

    Certain matters discussed in this press release may constitute
forward-looking statements within the meaning of federal securities

as compared to the last half of 2003; AmNet's 2004 loan production;

warehouse lines; the large concentration of the Company's loans in

economic conditions generally; the size of the national mortgage
market, including subprime loans; the stability of the subprime
mortgage secondary market; the predictability of the Company's
expenses and margins; the future correlation of volatility in forward
