PharmAthene Reports Year-End 2007 Financial Results

ANNAPOLIS, Md., March 31 /PRNewswire-FirstCall/ -- PharmAthene, Inc.
(Amex: PIP) a biodefense company developing medical countermeasures against
biological and chemical threats, today reported financial results for the year
ended December 31, 2007.
David P. Wright, President and Chief Executive Officer commented, "In 2007
we continued to advance both our corporate and product development objectives
and achieved a number of important milestones which included, obtaining
additional contract and appropriations funding for Valortim(TM) and
Protexia(R) and generating promising new data in each of these programs. We
also completed a merger with Healthcare Acquisition Corp. which provided a
stronger financial foundation with enhanced access to capital with which to
pursue our business objectives. Our goal was to use these resources to
accelerate our growth, which was recently demonstrated by the execution of an
agreement for the acquisition of Avecia's biodefense vaccines."
Current and Full Year 2007 Highlights
In addition to the recently announced sale and purchase agreement signed
with Avecia, PharmAthene also demonstrated significant achievements in 2007,
including:
-- Completing a merger with Healthcare Acquisition Corp. and building a
stronger financial foundation for the Company. As a result of the
merger PharmAthene obtained approximately $57.9 million in capital.

-- Receiving a contract for up to $13.9 million from the National
Institutes of Health to support the development of Valortim(TM) for use
as an anti-toxin therapeutic to prevent and treat inhalational anthrax
infection.

-- Obtaining up to an additional $2.4 million in funding for Valortim(TM)
in the FY 2007 and 2008 U.S. Congressional Appropriations budgets for
the Department of Defense.

-- Presenting new mechanistic data for Valortim(TM) showing that
Valortim(TM) may possess the ability to enhance macrophage killing of
Bacillus anthracis (anthrax) spores within macrophages, potentially
blocking the ability of the spores to develop into bacteria and
preventing toxin production and propagation of the infection.

-- Demonstrating new research showing that recombinant
butyrylcholinesterase (rBChE) may effectively block the formation of
amyloid fibrils, which are believed to be important precursors to
Alzheimer's disease.

-- Showing a therapeutic effect for Valortim(TM) in a new primate model of
established inhalation anthrax infection -- the African Green Monkey
model, which is believed to follow a similar disease course as would be
expected in humans exposed to aerosolized Bacillus anthracis (anthrax)
spores. The pilot study demonstrated 50% survival in Valortim(TM)-
treated animals compared to no animals in the control group; this was
perceived to be an encouraging survival result since the study animals
had bacteria multiplying in their blood and were poised to manifest
severe symptoms and death at the time they received treatment.

Financial Highlights
For the year ended December 31, 2007, PharmAthene recognized revenues of
$14.6 million compared to $1.7 million for the period ended December 31, 2006.
The Company's revenues consist primarily of contract and grant funding from
the U.S. government. The increase in revenue in 2007 is primarily
attributable to revenues of $14.6 million provided under the Department of
Defense advanced development and procurement contract for Protexia(R), which
was executed in September 2006.
PharmAthene's research and development expenses were $16.6 million for the
year ended December 31, 2007 and $7.3 million for the same period in 2006.
Research and development expense increased $9.3 million in 2007 compared to
2006 primarily as a result of increased process development and manufacturing
activities related to Protexia(R) and Valortim(TM) of $9.2 million, and
employee-related expenses, including stock compensation expense of $1.8
million. These increases were partially offset by reduced preclinical and
clinical activities related mostly to the Valortim(TM) clinical trial program.
General and administrative expenses for the Company in 2007 were $13.9
million compared to $8.5 million for the same period in 2006. The increase in
general and administrative costs in 2007 was attributable to increased
employee costs, a related increase in travel expense, increased stock
compensation expense, and increased facilities costs as PharmAthene relocated
its corporate headquarters in 2007 to larger facilities in Annapolis.
PharmAthene's net loss attributable to common shareholders for the year
ended December 31, 2007 was $17.7 million or $1.88 per basic and diluted
share.
Non-cash adjustments for the year ended December 31, 2007 included a $2.4
million credit that resulted from the cancellation of former PharmAthene
preferred stock warrants, a $0.9 million gain on the extinguishment of debt,
and stock compensation expense of $1.7 million.
As of December 31, 2007, cash, cash equivalents and short term investments
were $52.7 million, compared to $5.1 million at December 31, 2006. The $47.6
million increase in cash, cash equivalents and short term investments from
December 31, 2006 is primarily attributable to the August 2007 merger with
HAQ,
which resulted in net cash proceeds of $57.9 million and to the March
2007$10.0 million credit facility, partially offset by the funding of
operations
for fiscal year 2007.
On March 20, 2008, PharmAthene announced that the Company had signed a
sale and purchase agreement with Avecia. Under the agreement PharmAthene will
acquire the assets related to Avecia's biodefense vaccines business unit,
including a recombinant Protective Antigen (rPA) anthrax vaccine, a novel dual
antigen plague vaccine, RypVax(TM), and third generation anthrax vaccine
technology.
On March 28, 2008, Avecia received a letter from the Defence Science and
Technology Lab, a branch of the UK Ministry of Defence, advising Avecia of the
recent resource allocation decision of the US Department of Defense (DoD) and
that the DoD had decided not to fund Avecia's plague vaccine candidate beyond
the current contractual commitments. The parties are engaged in discussions to
amend the terms of the sale and purchase agreement to accommodate this change
in circumstances. The Company is still working towards closing in early April.
