Nektar Announces Financial Results for the Year and Fourth Quarter
2003

    SAN CARLOS, Calif.--(BUSINESS WIRE)--Feb. 2, 2004--Nektar
Therapeutics (Nasdaq:NKTR) today announced its financial results for
the year and fourth quarter ended December 31, 2003.
    For the year ended December 31, 2003, revenues were $106.3
million, compared to $94.8 million in 2002. In 2003, Nektar reported
product revenues of $27.3 million compared to $18.5 million for 2002,
and contract research revenues were $79.0 million for 2003, compared
to $76.4 million for the year ended December 31, 2002. The increase in
revenues by 12% for the year is due primarily to higher sales of
Nektar Advanced PEGylation products.
    For the twelve months ended December 31, 2003, the company
reported a net loss of $46.7 million or $(0.84) per share, compared to
a net loss of $107.5 million or $(1.94) per share for the year ended
December 31, 2002. The 2003 net loss includes $31.2 million in gain
related to the cancellation of outstanding indebtedness, including a
$26.9 million gain from privately negotiated debt exchange
transactions in the fourth quarter of 2003 and a $4.3 million gain
from the repurchase of $20.5 million of debt in privately negotiated
transactions in the second quarter of 2003.
    The company reported revenues of $25.6 million for the three
months ended December 31, 2003, compared to $22.6 million in the same
period in 2002. In the fourth quarter of 2003, product revenues were
$5.9 million compared to $5.2 million in 2002, and contract research
revenues totaled $19.7 million compared to $17.5 million in 2002.
    For the three months ended December 31, 2003, Nektar reported a
net income of $3.5 million or $0.06 per share compared to a net loss
of $31.1 million or $(0.56) for the same period in 2002. Net income
for the three month period includes a loss from operations of $19.9
million, interest expense of $4.8 million, a gain of $26.9 million
related to privately negotiated debt exchange transactions, $1.5
million of interest and other income, and a $0.2 million provision for
income taxes.
    As of December 31, 2003, the company reported cash, cash
equivalents and short-term investments totaling approximately $286.0
million compared to $304.2 million at the end of the third quarter
2003.
    In January 2004, in a privately negotiated transaction, Nektar
exchanged $9.0 million of outstanding 3.5% convertible notes due
October 2007 for 575,605 shares of common stock. In addition, in
January 2004, the company entered into privately negotiated
transactions with a limited number of holders of outstanding 3%
convertible notes due June 30, 2010, to convert approximately $36.0
million aggregate principal amount of such notes into approximately
3.2 million shares of common stock in exchange for cash payments of
approximately $3.1 million in the aggregate. As a result, the
liability for outstanding convertible notes and debentures as of today
stands at $315 million of which approximately $182 million is due at
or prior to October 2007, and approximately $133 million is due in
2010.
    For 2004, the company expects revenue growth of approximately
10-20%, a net loss between $85 and $95 million, and year-end cash,
cash equivalents and short-term investments of approximately $200
million.

    Summary of 2003

    "2003 was an exciting and fruitful year for Nektar," said Ajit S.
Gill, Nektar chief executive officer and president. "We started the
year by re-naming the company Nektar Therapeutics to reflect our
broadened drug delivery capabilities. During the year, we saw
substantial progress in several of our partner pipeline programs,
encouraging data on Exubera(R) (inhaled insulin), the broadening of
our Proprietary Products Program, and improvement in our balance
sheet. Our pipeline of 21 products now includes five products approved
in the U.S., four in pivotal or Phase III clinical trials, and 12
products in Phase I and II clinical testing."

    2003 and Early 2004 Partner Pipeline Progress

    --  Today, in a separate press release, Nektar disclosed a
        collaboration with Roche under which Nektar has licensed its
        proprietary PEG reagent for CERA (Continuous Erythropoiesis
        Receptor Activator).

    --  In January 2004, Celltech announced the initiation of Phase
        III trials for CDP 870 for Crohn's disease. CDP 870, which
        uses Nektar PEGylation, was also being tested in Phase III
        trials for rheumatoid arthritis.

    --  In November, Eyetech Pharmaceuticals presented data from Phase
        III trials of Macugen(TM), (PEGaptanib sodium), a potential
        treatment for age-related macular degeneration and diabetic
        macular edema, both leading causes of blindness.

    --  In June, Celltech's CDP 860, a PEGylated antibody fragment
        drug in testing for cancer, completed a small Phase II
        proof-of-concept study.

    --  In March, Pfizer's (formerly Pharmacia's) SOMAVERT(R), which
        uses Nektar PEGylation, was approved by the U.S. Food and Drug
        Administration for the treatment of certain patients with
        acromegaly.

    --  In addition, during 2003, Nektar partners initiated clinical
        trials for four products, including InterMune's PEG-Alfacon
        for hepatitis C; Celltech's CDP 791, a PEGylated antibody
        fragment drug for cancer; Unimed's inhaled MARINOL(R),
        Nektar's first MDI application, being developed for use in
        multiple indications; and Chiron's inhaled Tobi(R), a
        next-generation inhaled, powder tobramycin product for the
        treatment of Pseudomonas aeruginosa in cystic fibrosis
        patients.

    Exubera(R) (inhaled insulin) Progress

    In June, Pfizer and Aventis presented additional Phase III data at
the American Diabetes Association Conference in New Orleans comparing
Exubera(R) to rosiglitazone, an oral hypoglycemic agent used to reduce
the body's resistance to the action of insulin as a way of lowering
blood glucose. The data suggested that Exubera(R) may provide
acceptable glycemic control to significantly more subjects than
rosiglitazone in type 2 diabetes patients not optimally controlled on
diet and exercise.
    Advanced-stage clinical studies are continuing for Exubera(R)
(inhaled insulin) for the treatment of diabetes developed by Nektar
for Pfizer and their partner Aventis Pharma. The determination as to
if or when to file a New Drug Application or equivalent European
regulatory filing with respect to Exubera(R) will be made by Pfizer
and their partner Aventis at their discretion.

    Proprietary Pipeline Progress

    In the first quarter, an inhaled small molecule entered clinical
testing. Phase I clinical trials for this molecule are on-going. Over
the next few years, Nektar intends to significantly increase the
number of products it takes through Phase I clinical testing and, in
some cases, Phase II, before offering the products to Nektar's
biopharmaceutical partners for commercialization. Nektar could have an
additional 1-2 products in clinical trials as part of this program by
the end of 2004.
