    Results for Fourth Quarter 2004

    For the quarter ended December 31, 2004, consolidated revenues were $12.3
million, a 7% increase compared to consolidated revenues of $11.5 million for
the fourth quarter of 2003.

    Product sales decreased 7%, in the fourth-quarter 2004 compared to the same
period in 2003. Fourth-quarter 2004 device lease fees, a component of device
revenues, generated 6%, or $0.6 million, more revenue than the fourth quarter of
2003. These recurring fees generally contribute more than 90% of device
revenues. Device revenues also include device sales, which tend to be sporadic
in nature and which increased $0.3 million in the fourth quarter of 2004
compared to the fourth quarter of 2003. Overall, device revenues totaled $11.7
million for the fourth quarter of 2004 compared to $10.8 million for the same
period in 2003, representing an 8% increase year over year.

    Fourth-quarter 2004 gross profit was $6.9 million, up $0.3 million compared
to the same period a year ago. This is primarily due to changes in Embrex's
product mix.

    Operating expenses were down $0.2 million, or 3%, to $7.3 million in the
fourth quarter of 2004 compared to $7.5 million during the same period in 2003,
primarily due to decreases in research and development expenses that offset
increases in G&A and Sales & Marketing.

    G&A expenses were $3.5 million for the fourth quarter of 2004, up $1.5
million or 75% compared to the same period of 2003. The increase in G&A expenses
from 2003 was primarily due to $0.6 million of expenses related to the
implementation of changes to internal controls for Sarbanes-Oxley (SOX)
compliance, increases in staff-related expenses driven by the Company's growth,
start-up costs for Embrex Poultry Health, and higher insurance premiums due to
increased insurance coverage. The balance of the increase was a reclassification
of patent-related legal expenses previously reflected in R&D.

    Fourth quarter Sales & Marketing operating expenses increased $0.2 million
to $0.9 million from 2003 to 2004.

    R&D expenses decreased $1.9 million primarily due to the purchase and
write-off of the gender sort system from Advanced Automation in 2003. The
write-off increased 2003 R&D expenses $2.3 million. Increased spending on
start-up manufacturing processes at the Embrex Poultry Health facility offset
some of the decrease.

    Income tax benefit totaled $0.9 million for the fourth quarter of 2004 which
was $0.1 million more than the tax benefit in the same period in 2003.

    Consolidated net income for the fourth quarter 2004 increased to $0.6
million, a four-fold increase over 2003 fourth quarter net loss of $0.2 million.
Diluted earnings per share were $0.08 for the fourth quarter 2004 versus ($0.02)
for the same period in 2003. This increase in net income is primarily
attributable to the write-off of the gender sort system purchased from Advance
Automation that decreased net income for the fourth quarter of 2003 by $2.3
million.



    Results of Full-Year 2004

    Consolidated revenues in 2004 totaled $48.7 million, an increase of 6% over
2003 revenues of $46.0 million. Device revenues totaled $46.2 million for 2004,
an increase of 6% over 2003 revenues of $43.5 million. Most of the device
revenue increase was attributable to a 7%, or $3.0 million, increase in
recurring device lease fees. This was due to an increase in the Inovoject(R)
system customer base, and new Egg Remover(R) system installations. Other
revenues decreased 12% from $0.6 million in 2003 to $0.5 million in 2004. A 3%
increase in product revenue, consisting primarily of Bursaplex(R) sales, also
contributed to the increase in consolidated revenues. Gross profit for 2004 was
$28.6 million, a 5% increase over gross profit of $27.1 million for the same
period in 2003.

    Consolidated gross margin remained at 59% from 2003 to 2004.

    Consolidated operating expenses were $24.4 million for 2004 versus $22.5
million for 2003. G&A expenses were $11.0 million in 2004, up 54% from $7.1
million in 2003. The increase in G&A expenses from 2003 to 2004 was principally
due to continued growth of expenses for the Company's Inovocox(TM) production
facility, $0.9 million related to accounting and internal controls to comply
with the Sarbanes-Oxley Act, increased insurance premiums due to increased
property and product liability exposures, patent-related legal fees previously
recorded as R&D expense, and staff-related increases in support of the business.

    2004 Sales and Marketing expenses increased $0.1 million from $2.8 million
in 2003 to $2.9 million for 2004. This increase is due to additional personnel
in Marketing to market and support the Company's devices and to prepare and
support Inovocox(TM) after registration is achieved.

    Research and development expenses were $10.5 million in 2004, a $2.1 million
decrease from $12.5 million in 2003. The decrease in R&D expense from 2003 to
2004 is primarily due to the write-off of the gender sort system purchased from
Advanced Automation, which increased 2003 R&D expenses by $2.3 million.

    Other income decreased $3.4 million from 2003 to $0.3 million for the same
period of 2004, primarily attributable to the $5.0 million financial settlement
less legal expenses of $1.3 million associated with Fort Dodge. This resulted in
net income of $7.6 million for 2003, which decreased 56% to $3.3 million in
2004. Diluted net income per common share was $0.40 for 2004 based on 8.3
million average shares outstanding, compared to diluted net income per common
share of $0.91 based on 8.4 million average shares outstanding for 2003. The
2003 net income includes $3.7 million, or $0.44 per share attributable to the
Fort Dodge settlement.

    The effective tax rate of 9% for 2003 increased to 26% for 2004. Income
Taxes totaled $1.2 million in 2004, a $0.4 million increase from $0.8 million in
2003. Income tax expense and the effective tax rate increased over 2003 due to a
$0.2 million increase in the valuation allowance versus a $1.7 million decrease
in 2003, a lower R&D tax credit calculation in 2004 compared to 2003, an
increase in 2004 business activities in foreign markets compared to 2003, and
the use of NOL's in Embrex Europe for the 2003 Fort Dodge settlement during
2003. These were partially offset by miscellaneous decreases including
adjustments for amended income tax returns and the reevaluation of tax and
inventory accruals.



    Embrex uses earnings before interest, taxes, depreciation and amortization
(EBITDA) as an additional performance measure. Embrex believes that EBITDA,
which is a non-GAAP financial measure, provides investors with supplemental
information about its financial performance. In compliance with the Securities
and Exchange Commission's Regulation G, the Company has provided a
reconciliation of EBITDA to GAAP net income, following the financial statements
below.

    EBITDA decreased $3.3 million to $10.4 million for 2004 from $13.7 million
for 2003. This is primarily due to the non-recurring $3.7 million Ft. Dodge
settlement in 2003.

    At December 31, 2004, cash and cash equivalents totaling $4.5 million were
$5.1 million lower than the $9.6 million on hand at December 31, 2003. This was
principally due to a $4.3 million decrease in cash provided by long-term debt,
as well as the $4.3 million decrease in net income resulting from the $5.0
million settlement with Fort Dodge in 2003 and an increase in Sarbanes- Oxley
related expenses. A $2.2 million increase in cash used to repurchase shares of
common stock also contributed to the decrease in cash balances. Investing
activities, primarily device purchases, and other capital expenditures consumed
$12.6 million and the Embrex Poultry Health facility required $1.3 million. This
was partially offset by a $2.7 million decrease in cash used for investing in
capital expenditures, the issuance of common stock for $0.7 million, and the
issuance of $2.1 million of long-term debt from BB&T as a part of our
construction/term loan.

    "Diversity in a company's product portfolio and geographic reach is a well
documented strategy of success and it was proven at Embrex in 2004. As Asia
continued to struggle against avian influenza outbreaks, Brazil and North
America offset the impact with continued growth. All Embrex regions were
profitable this quarter, except for Latin America which was impacted by upfront
costs associated with growth in machine installations - a nice problem to have,"
said Randall L. Marcuson, President and Chief Executive Officer. "We believe our
market performance in a challenging year was good. Had Asia not had avian
influenza we believe it would have been very good. We made much of it up as we
worked to improve our gross profit in the face of the revenue challenge.
Unfortunately, the costs associated with implementation of the requirements of
Sarbanes-Oxley were substantial. The magnitude of those costs only became
apparent at the end of 2004 and during the closing process in January and
February after we were advised of additional costs by our independent auditors."
