RESEARCH TRIANGLE PARK, N.C. -- November 08, 2012

BioCryst Pharmaceuticals, Inc. (NASDAQ:BCRX) today announced financial results
for the third quarter and nine months ended September 30, 2012.

“Despite the recent setbacks, we are focused on advancing the other promising
assets in our portfolio. We are evaluating operational changes to decrease our
cost structure and to best position us to achieve value creating milestones.
In addition, we are continuing to work on the Presidio Pharmaceuticals
merger,” said Jon P. Stonehouse, President & Chief Executive Officer.

Third Quarter Financial Results

For the three months ended September 30, 2012, revenues increased to
$5.8million, from $5.2 million in the third quarter of 2011. This increase
resulted primarily from the recognition of $2.8 million of deferred royalty
revenue from Shionogi related to RAPIACTA^® sales, and was largely offset by a
decrease in collaboration revenue from the Department of Health and Human
Services/Biomedical Advanced Research and Development Authority (HHS/BARDA)
contract for the continued development of peramivir. The recognition of
RAPIACTA^® royalty revenue had no impact on the Company’s cash balance, as the
underlying royalty payments are directed to pay interest expense on the
Company’s non-recourse notes payable.

Research and development (R&D) expenses for the third quarter decreased to
$12.1million from $15.1million in the third quarter of 2011. In 2012, lower
development costs associated with the peramivir and ulodesine programs were
partially offset by higher development costs associated with the preclinical
BCX5191 and BCX4161 programs.

General and administrative (G&A) expenses for the third quarter decreased to
$1.6million compared to $3.0million in the third quarter of 2011, largely
due to reductions in administrative expenses during 2012 associated with the
continued realization of cost containment measures.

Interest expense related to the non-recourse notes was $1.2million in the
third quarter of 2012 and 2011. In addition, a $0.6 million mark-to-market
loss on the foreign currency hedge was recognized in both the third quarter of
2012 and 2011. These hedge losses resulted from changes in the U.S.
dollar/Japanese yen exchange rate related to the foreign currency hedge
agreement entered into in conjunction with the RAPIACTA^® royalty monetization
transaction.

The net loss for the third quarter 2012 was $9.7million, or $0.19 per share,
compared to a net loss of $14.5million, or $0.32 per share, for the third
quarter 2011.

Cash and investments totaled $43.8 million at September 30, 2012, a $13.9
million decrease from the $57.7 million balance at December 31, 2011. Net
operating cash use for the third quarter of 2012 was $9.7 million and excludes
$2.5 million in proceeds from sales of common stock through the Company’s
at-the-market offering during the quarter, as well as collateral payments
under the foreign currency hedge agreement. Net operating cash use for the
first nine months of 2012 was $29.7 million.

Year to Date Financial Results

For the nine months ended September30, 2012, total revenues increased to
$22.2 million from $14.4 million in the same period of 2011. The increase was
due to the recognition of $7.8 million of previously deferred
forodesine-related revenue in the first quarter 2012, as well as the
recognition of $2.8 million deferred royalty revenue from Shionogi related to
RAPIACTA^® sales in the third quarter of 2012. The aggregate revenue increase
was partially offset by a decrease in peramivir collaboration revenue from
HHS/BARDA due to a reduction of peramivir development activity in 2012, as
compared to 2011.

R&D expenses decreased to $40.4million for the nine months of 2012 from $43.0
million in the same period of 2011. A decrease in 2012 development costs
related to the ulodesine and peramivir programs were partially offset by
higher BCX5191 and BCX4161 development costs, as compared to the same period
of 2011. Expenses for 2012 included the recognition of $1.9 million of
non-cash, previously deferred expenses associated with forodesine and the
related transfer of development activity to Mundipharma International Holdings
Ltd. in the first quarter of 2012.

G&A expenses decreased significantly to $4.9million for the nine months ended
September30, 2012 from $9.9million for the nine months ended September 30,
2011, due to the 2011 relocation of BioCryst’s corporate headquarters and to
lower third party professional expenses in 2012 associated with the continued
realization of cost containment measures.

The net loss for the nine months ended September30, 2012 decreased to
$28.0million, or $0.57 per share, compared to a net loss of $43.8million, or
$0.97 per share for the same period last year.

Clinical Development Update & Outlook

  *In a separate press release issued yesterday, BioCryst announced that the
    independent Data Monitoring Committee (DMC) overseeing the Company's Phase
    3 clinical trial of intravenous (i.v.) peramivir completed its review of
    the planned interim analysis. The DMC reported that the recalculated
    sample size is greater than the predefined futility boundary of 320
    subjects and recommended that the study be terminated for futility.
  *In October, BioCryst and privately held Presidio Pharmaceuticals, Inc.
    signed a definitive merger agreement to create a focused, clinical stage
    biopharmaceutical company with lead programs in high-value antivirals and
    orphan disease indications, initially focused on chronic hepatitis C virus
    (HCV) infection and hereditary angioedema (HAE).
  *Last week, BioCryst announced the withdrawal of its Investigational New
    Drug application (IND) for the antiviral nucleoside BCX5191, following a
    discussion with the U.S Food and Drug Administration (FDA). The Company
    intends to initiate additional preclinical studies in animals with HCV
    infection before the end of 2012 and to then decide whether to continue
    development of BCX5191, based on the results of the studies.
  *Additional preclinical results regarding BCX5191 will be presented at The
    Liver Meeting®, the 63rd Annual Meeting of the American Association for
    the Study of Liver Diseases (AASLD) in Boston, November 9 to 13, 2012.
  *In September, the Company concluded the Scientific Advice Process for
    ulodesine with the European Medicines Agency. Based on this feedback, the
    ulodesine Phase 3 development plan has undergone modest revision. The
    Company continues to seek a partner for Phase 3 development and
    commercialization.
  *The Company remains on track to initiate its BCX4161 for hereditary
    angioedema Phase 1 program before the end of 2012. The main success
    factors for the BCX4161 Phase 1 trial are to demonstrate safety, adequate
    drug exposure via oral administration and pharmacodynamic effect on
    kallikrein inhibition.
  *Promising preclinical results for BCX4430, a broad-spectrum antiviral
    nucleoside analog that has demonstrated activity against multiple viruses,
    will be presented at the 2nd Antivirals Congress in Cambridge, MA,
    November 11 to 13, 2012. The presentation will describe the antiviral
    activity of BCX4430 in the currently accepted model for demonstrating
    potential efficacy against yellow fever virus infection.

Financial Outlook for 2012

Based upon current trends and assumptions, as well as the Company’s planned
operations, BioCryst expects 2012 net operating cash use to be in the range of
$37 to $43 million, and its 2012 total operating expenses to be in the range
of $57 to $69 million, unchanged from previous guidance announced in August
2012. BioCryst’s 2012 financial results are heavily dependent on
peramivir-related operating expenses, which are largely a function of the rate
of enrollment in the Company’s Phase 3 clinical trial.

that ongoing and future preclinical and clinical development may not have
positive results; that the companies or licensees may not be able to continue
future development of current and future development programs; that such
development programs may never result in future product, license or royalty
payments being received; that the companies may not be able to retain their
current pharmaceutical and biotechnology partners for further development of
its product candidates or may not reach favorable agreements with potential
pharmaceutical and biotechnology partners for further development of product
candidates; that their actual cash burn rate may not be consistent with its
expectations; that 2012 operating expenses and cash usage will be within
management’s expected ranges; that BioCryst or Presidio may not have
sufficient cash to continue funding the development, manufacturing, marketing
