PFIZER TABLES BID FOR PHARMACIA

PHARMACIA EXPECTED TO REPORT MUSD 686 PROFIT IN SECOND QUARTER

CORPORATE
PFIZER TABLES BID FOR PHARMACIA
Sverige-Nytt/Swedish Digest, 2002-07-22

Pfizer is to buy Pharmacia for 60 billion dollars. The acquisition will be paid
for in shares, and the bid represents a premium of 44 percent to Pharmacia
shareholders.

"Pharmacia was actually not for sale, but when you get an offer as good as this,
the shareholders must get the chance to have their say", says Hakan Astrom, who
serves on the group's executive management and is President of Pharmacia AB.

Swedish ownership in the new Pfizer will be less than one percent. It is too
early to say how the deal will affect operations on Sweden.

"We have, after all, tremendously unique businesses in Sweden, above all on the
production side; for example Nicorette, the biotechnology operation in Strangnas
and our major investment in Uppsala. These will probably continue to play an
important part in the new company", says Astrom.

Hakan Mandahl, Vice President of the Swedish Association of the Pharmaceutical
Industry, believes that this definitively signals the end of Pharmacia's
research in Sweden. According to Hakan Astrom, on the other hand, the research
conducted in Sweden is specialized and needed. (TT)

PHARMACIA EXPECTED TO REPORT MUSD 686 PROFIT IN SECOND QUARTER
Reuters Ekonominytt, 22 July  2002

Pharmacia is predicted to report a profit of 686 million dollars before tax in
the year's second quarter. In the full year, Pharmacia is expected to report a
profit of 2,670 million dollars. Sales in the second quarter are expected to
total 3,559 million dollars, and 14,245 million dollars in the full year. On 15
July, Pfizer tabled a bid for Pharmacia, a deal that is expected to be valued at
53 million dollars. According to analysts, the focus ahead of the report on the
merger between Pfizer and Pharmacia is on the growth in sales, in particular, of
the product Celebrex, which is used to treat rheumatism.

They are also looking forward to news on the launch of Bextra, and how it went.
Sales of Celebra are forecast at 744 million dollars with sales of Bextra
predicted at 92 million dollars.

"Of course, the focus is on what is happening in the Pfizer merger. "but
(another) focus (is) on the usual things, such as the Cox 2-platform and whether
they have managed to get Bextra out in the USA on time", says an analyst.
