    Results for First-Quarter 2005
    For the quarter ended March 31, 2005, consolidated revenues were $12.8
million, a 7% increase compared to consolidated revenues of $12.0 million for
the first-quarter of 2004.

    Product sales increased nearly two-and-one-half times in the first-quarter
2005 compared to the same period in 2004. First-quarter 2005 recurring device
lease fees, a component of device revenues, generated 10%, or $1.0 million, more
revenue than the first-quarter of 2004. 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 decreased $0.6 million in
the first-quarter of 2005 compared to the first-quarter of 2004. Overall, device
revenues totaled $11.9 million for the first-quarter of 2005 compared to $11.5
million for the same period in 2004, representing a 4% increase year over year.



    First-quarter 2005 gross profit was $7.3 million, up $0.2 million compared
to the same period a year ago. This is primarily due to changes in Embrex's
product mix, including lower device sales.

    Operating expenses increased $0.9 million, or 17%, to $6.3 million in the
first-quarter of 2005 compared to $5.4 million during the same period in 2004.
Details are described below.

    General and administrative ("G&A") expenses were approximately $2.6 million
for both the first quarter of 2005 and 2004.

    Sales & Marketing expenses were $1.0 million during first quarter 2005, an
increase of 52% or $0.3 million over the same period in 2004. The increase is
due primarily to support business growth and pre-launch activities for the
Inovocox(TM) vaccine.

    Research & Development ("R&D") expenses increased $0.6 million or 25% over
first quarter 2004 expenses. This increase is primarily due to increases in
staff and preliminary production-related expenses associated with the new Embrex
Poultry Health Inovocox(TM) vaccine production facility and expenses related to
the gender sort project.

    Income taxes totaled $0.5 million for first quarter 2005, which is $0.1
million lower than for the same period in 2004. The effective tax rate for first
quarter 2005 is 45%, compared to 37% for the same period in 2004. In the first
quarter of 2005, withholding taxes accounted for 17 percentage points of the 45%
tax rate, and U.S. and non-U.S. income taxes represented the remaining 28
percentage points. In the first quarter of 2004, withholding taxes accounted for
7 percentage points of the 37% tax rate, and U.S. and non-U.S. income taxes
represented the remaining 30 percentage points. Net operating loss
carry-forwards used in 2004 to offset income taxes in non-U.S. jurisdictions are
no longer available in 2005, which also contributes to the higher effective tax
rate.

    Consolidated net income for the first-quarter 2005 decreased to $0.6 million
as compared to 2004 first-quarter net income of $1.1 million. Diluted earnings
per share were $0.07 for the first-quarter 2005 versus $0.13 for the same period
in 2004. The $0.5 million decrease in net income is primarily attributable to
the 2005 increase in operating expenses described above and the $0.6 million
decrease in device sales and is partially offset by revenue growth.

    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 accordance 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 $0.5 million to $2.7 million for the first- quarter of
2005 from $3.2 million for the same period in 2004 primarily due to the decrease
in net income described above.



    At March 31, 2005, the Company's cash and cash equivalents totaled $3.2
million compared to $4.5 million at December 31, 2004. The decrease is primarily
attributable to $2.6 million for purchases of devices and other capital items,
as well as a $1.3 million reduction in non-debt current liabilities. In
addition, the decrease in cash reflects a $0.5 million investment in patents and
other non-current assets. This was partially offset by a $1.5 million increase
in cash provided by the draw down of short-term debt, and another $2.2 million
provided by net income after depreciation and amortization are added back.

    "While we continue to have concerns about how 2005 will unfold in terms of
U.S. egg sets and avian influenza in Asia, the first three months of 2005 got us
off to a good start," said Randall L. Marcuson, President and Chief Executive
Officer. "While recurring device revenues and product sales increased by low
double digits, that rate may not sustain itself over the year, but we believe a
total revenue goal of $52.5 million or better for 2005 may be attainable. This
revenue goal represents nearly an 8% increase over 2004."
