    Fourth-quarter total revenues remained unchanged at $11.5 million for both
2003 and 2002.  The Company's fourth-quarter device revenues of $10.7 million
increased $0.5 million over 2002 device revenues of $10.2 million.  Revenues
from product sales decreased $0.3 million from $0.8 million in 2002 to
$0.5 million in 2003, partially offsetting this gain.  In addition, other
revenues derived from grant and miscellaneous revenue decreased from
$0.4 million in the fourth quarter of 2002 to $0.2 million for the same period
of 2003.  As noted in prior quarters, device sales (included in device
revenue) and other revenue such as grants or outside funding vary from
quarter-to-quarter.

    Total operating expenses were $7.5 million for the fourth-quarter 2003
compared to $5.2 million for the same period in 2002.  Research and
development expenses increased $2.4 million, primarily due to expenses of
$2.3 million associated with the write down of the Gender Sort system
purchased from Advanced Automation, Inc.  Other expense increases were not
significant.

    Fourth-quarter loss before taxes was ($1.0) million, or $2.7 million less
than 2002 income before taxes of $1.7 million.  This loss is primarily due to
the Company's write down of the $2.3 million purchase of the Gender Sort
system from Advanced Automation. As a result of the loss before taxes of
$1.0 million, estimated income taxes for the fourth quarter of 2003 were
reduced. In addition the Company's evaluation of the year end deferred tax
asset resulted in a significant increase to the deferred tax asset and a
reduction in the provision for income taxes. Together the above items resulted
in a $1.0 million net reduction in income tax compared to fourth quarter 2002
income tax.  Fourth-quarter net loss was ($0.2) million, a decrease of
$1.6 million in comparison to net income of $1.4 million for the same period
in 2002. Diluted earnings per share for the fourth-quarter were ($0.02) per
share on 8.5 million weighted average shares outstanding, compared to diluted
earnings of $0.16 per share on 8.5 million weighted average shares outstanding
for the same period in 2002.

    Fourth-quarter 2003 gross margin decreased from 60% to 57% reported in the
comparable quarter of 2002 primarily due to Advanced Technology Program (ATP)
grant funding with no associated cost of revenue received during the fourth
quarter of 2002 that did not recur in 2003.

    The Company uses earnings before interest, taxes, depreciation and
amortization (EBITDA) as an additional performance measure. The Company
believes that EBITDA, which is a non-GAAP financial measure, provides
investors with supplemental information about the Company's 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 was $0.4 million for
the fourth quarter of 2003, a decrease of 87% or $2.7 million compared to the
same period in 2002.  It includes a $2.3 million write down of the Gender Sort
system purchased from Advanced Automation.

    Results of Full-Year 2003

    For the full-year ended December 31, 2003, total revenues were
$46.0 million, a 2% increase over total revenues of $45.3 million for the
full-year 2002. This is primarily attributable to an 8%, or $3.3 million
increase in device revenues which was offset by product sales that declined by
$1.1 million and other revenue from grants and research and development
funding that decreased by $1.5 million year over year.

    Full-year 2003 gross margin was 59%, down from 61% in 2002 primarily due
to lower ATP funding and 2002 funding from Cobb-Vantress that did not recur in
2003, each of which had no associated cost of revenue.

    Operating expenses were up 17% to $22.5 million in 2003 compared to
$19.3 million in 2002.  Operating expenses for 2003 include a $2.3 million
write down for the Gender Sort system purchased from Advanced Automation.

    General and administrative (G&A) expenses were $7.1 million in 2003, up 8%
from $6.6 million in 2002. The increase in G&A expenses from 2002 to 2003 was
primarily due to increased expenses related to legal and accounting services
incurred to comply with the Sarbanes-Oxley Act; additional facilities support;
the Company's Inovocox(TM) facility under construction; increased insurance
premiums due to increased property and product liability coverage as well as
an overall increase in premium rates for the 2003 insurance market; and staff-
related increases in support of the business.

    Sales and marketing expenses totaled $2.8 million in 2003, an increase of
12% over 2002 expenses of $2.5 million.  The increase from 2002 to 2003 is
primarily due to increased sales tax assessments, increased sales and
marketing efforts and staff-related increases to support the business.

    R&D expenses were $12.5 million in 2003 compared to $10.2 million in 2002.
The increase from 2002 to 2003 is primarily due to the $2.3 million write down
of the Gender Sort system purchased from Advanced Automation.

    Total other income was $3.8 million in 2003, a $3.6 million increase over
2002. This is primarily attributable to the $5.0 million Fort Dodge litigation
settlement in June 2003, which contributed $3.7 million of other income to the
second quarter of 2003 after accounting for legal expenses.

    Income before taxes for 2003 was $8.4 million, or $0.2 million less than
2002 income before taxes of $8.6 million.  Income taxes totaled $0.8 million
for 2003, a $0.7 million decrease in comparison to 2002.  The effective tax
rate for 2003 was 9% in comparison to 17% in 2002.  The lower effective tax
rate for 2003 was the result of the deferred tax asset evaluation that
increased the deferred tax asset and lowered the recorded income tax provision
expense.  Due to net operating loss carry forwards in Embrex Europe, Ltd.,
which offset the income tax effect of the Fort Dodge settlement, there was no
income tax provision recorded for the settlement in 2003. Consolidated net
income for 2003 increased to $7.6 million, 6% higher than 2002 net income of
$7.2 million. The increase in 2003 net income compared to 2002 was primarily
due to the $3.7 million settlement of the Company's litigation with Fort Dodge
net of legal expenses, offset by the $2.3 million write down of the Gender
Sort system. Net income per common share was $0.91 for 2003 based on 8.4
million weighted-average diluted shares outstanding, compared to net income of
$0.82 per share based on 8.7 million weighted average diluted shares
outstanding in 2002.

    EBITDA increased 1% to $13.7 million for 2003 from $13.6 million during
the same period of 2002.  At December 31, 2003, cash and cash equivalents
totaling $9.6 million were $1.6 million higher than the $8.0 million on hand
at December 31, 2002.  This was principally due to cash received from
financing the construction of the Embrex Poultry Health facility and a
favorable currency translation adjustment, offset by a $2.1 million decrease
in cash provided by operations and an $8.2 million increase in cash used for
investing in capital expenditures.  EBITDA includes the $3.7 million
settlement of the Company's litigation with Fort Dodge net of legal expenses,
and the $2.3 million purchase and write down of the Gender Sort system from
Advanced Automation.

    "The highlights at the beginning of this release demonstrate that Embrex
is poised to enter a new era in the field of in ovo technology.  We broadened
our patent base, constructed our first vaccine manufacturing facility, and
modestly grew our Inovoject(R) system and other device revenues in the face of
global industry challenges and the appearance of limited competitive
activity," said Randall L. Marcuson, President and Chief Executive Officer of
Embrex.  "Approximately a year ago, despite recognizing we would face certain
industry challenges, we decided to continue investing in key research and
development programs. Today, we believe we made the right decision. Our
Inovocox(TM) vaccine program remained on track and on budget while
advancements in our Gender Sort program lead us to believe we will have
sampling and assay techniques that improve our chances for application to a
broader market that includes the broiler industry - despite a delay in the
overall project.  As we continue to move these projects forward, 2004 will be
another investment year for us.  While we anticipate modest growth in the near
term, we continue to believe these projects represent significant potential
for the company."
