Pfizer To Acquire Wyeth


Strategic rationale

Q:   Well, today Pfizer announced that the company is acquiring Wyeth. What's
     the rationale behind that decision?

Jeff Kindler (JK): The combination of Wyeth and Pfizer is going to create the
     world's premier global pharmaceutical business. It's a very exciting
     opportunity to combine the terrific assets and people of both companies.
     We'll have a company that's diverse and flexible and has the scale to
     compete in this very dynamic and changing healthcare environment. We'll be
     able to be a leader in primary care and specialty care, in human health,
     animal health and consumer health, in vaccines and biologics and small
     molecules, in the developed world and the emerging world. And we'll be able
     to create more value for our patients and our shareholders and other
     customers.


Q:   Why are you supporting the transaction?

Bernard Poussot (BP): We believe that we can do much more and much faster in
     this combination. And the reason we've got an attractive offer from Pfizer
     is that Wyeth became more and more attractive to Pfizer over the years. And
     the reasons are that we've built one of the premier capacities in
     biotechnology. We embraced this technology in the early '90s and became the
     third-largest biotech company today in the world.


     We've also produced one of the most successful vaccines in the history of
     mankind, the first pneumococcal vaccines for children. We've also built a
     OTC Division, which I think is very important for Pfizer. And lastly, even
     in our Animal Health Division, we've been very conscious of very
     significant diseases. It's now a big


     concern to populations, like avian flu. We were first to bring in a vaccine
     against avian flu.

     So in combining all these businesses I think we've built the most
     diversified biopharmaceutical company, and that's what made Wyeth very
     attractive to Pfizer. So this combination will help us just to accelerate
     the strategic realisation of what I just presented.


Q:   You have said in the past - and I'm quoting now, that "the large deals run
     the risk of disruption and integration challenges." Why is this going to be
     different?

JK:  Well, it's certainly true that you have to do a lot of hard work to make
     sure an integration of two great companies like these works well. But this
     is a very different kind of transaction than some of the large pharma
     mergers of the past. As Bernard said, Bernard and his team have built a
     tremendous, diversified company, way ahead of people on biologics and on
     vaccines. I believe, if I'm not mistaken, the vaccine saves more than one
     baby a day, every day in the year. It's just a terrific business.

     And what we're going to do here is very different than what's happened in
     the past. We're going to have separate business units in primary care, in
     specialty care, animal health, consumer, nutritional. And each of these
     businesses will operate with a high degree of independence while still
     benefiting from the scale of the larger organisation.

     And Bernard and I have talked from the very beginning about how important
     it is to preserve the innovation represented by our research labs. That's
     what is the future of any biopharmaceutical company. So we're going to be
     very careful how we go about this, and we're going to do it as quickly as
     we can, but thoroughly and fairly. We want to get the best possible people
     to be supporting and leading our various businesses and activities. And I
     think we're going to really do a great job on this because our cultures and
     our organisations are very compatible.


Q:   Why not remain an independent company?

BP:  I think what this combination is going to bring, the financial power and
     the abilities to really put all our resources behind those innovations.
     It's a tough time for this industry. The diseases to fight are still many.
     We have, for example, put in motion more than 10 projects in alzhaimers.
     That's one of the biggest issues of our times. This requires a phenomenal
     amount of resources, not only the key talents we've been able to assemble
     but also the financial resources and the time to get to the finish line.

     So I think it's good news, that these two organisations are going to
     coalesce to make this fight a victory as soon as possible.


Q:   How is this going to affect the loss of exclusivity of Lipitor?

JK:  Well, we are going to lose exclusivity on Lipitor. That's a fact. But what
     this transaction - among many other benefits - does is it enables us to
     really definitively address the significant revenue loss represented by the
     loss of exclusivity of Lipitor at the end of 2011. And that will really put
     us in position to go through that period of time and grow very profitably
     going forward in the future. And it really addresses that in a very
     meaningful way.



Employees and customers


Q:   How about the employees? How is this combination going to affect the
     employees?

JK:  Well, both companies have terrific people. They're just great people. And
     every company is a function of the quality of the people and the quality of
     the individuals. Bernard and his team have assembled terrific leaders from
     around the world. I believe we've done the same at Pfizer. And obviously
     there are going to be tremendous opportunities for a lot of people in both
     companies, as we build and grow our business. At the same time, it's a fact
     that in a merger like this, we're going to have to make some difficult
     decisions and some hard choices about eliminating positions. That's the
     nature of these kinds of things because we have to be efficient but what we
     both are deeply committed to is fairness and respect for people, doing the
     right things and making sure that the best possible people get the best
     possible opportunities.


Q:   What impact will this transaction have on patients, physicians and other
     customers?

JK:  Well, one thing that Bernard and I and our companies have fundamentally in
     common is we're all about the patients. Our whole enterprise is about
     serving patients and meeting unmet medical needs. That's why people come to
     work at great companies like Wyeth and Pfizer. That's our core mission.

     And we believe that this transaction is going to enable us to better serve
     patients and other customers and stakeholders around the world - meet their
     needs more quickly, more effectively. Bernard just referenced one way in
     which we hope to be able to do that. You know drug discovery and
     development is a very, very expensive and very risky enterprise, and the
     ability to bring to bear significant resources and scale to find new cures
     and treatments for people is a very important thing. And we believe that
     the combination is really going to enable us to address unmet medical needs
     around the world, much more effectively and much more quickly.


Q:   Let me ask you for your take on that question. How do you think that this
     combination is going to affect patients and physicians and customers?

BP:  In short, I think the world needs this combination to be successful,
     because we have the big appetite for changing the lives and lifestyle of
     people around the world. I mean, that's our mission. And the public
     sometimes doesn't realise that this is really the intensity of being in
     this industry. It's not the ideas that are lacking; it's more the steady
     focus and resources needed to get to the finish line.

     I think in combining two companies that are very complementary, which have
     looked at very different aspects of life, and putting them together with
     the financial resources we can mobilise together, can be very good news for
     patients around the world.



Global opportunities


Q:   You've both mentioned that this combination - and you've used the word
     "transform" - transform to help our industry. Can you conclude by
     explaining how this combined company is going to compare to other
     healthcare companies?

BP:  We'll be obviously number one worldwide. More remarkably, even, we'll be
     number one in every continent around the world, which is important because
     there are some fast-growing regions of the world where scale will be
     important, more and more. I think, not only that, we'll be able to mobilise
     resources in research, which as we just said is the engine for growth like
     never, ever before.

     And money is not everything. You need the talent of people and I think
     we'll be also able to not only retain but also continue to attract the best
     minds, the best scientific minds around the world, the best technology and
     the best technicians and engineers to make those products available to a
     large number of patients and families.

JK:  I would just add - I agree with everything Bernard said - I would just add
     to that, that the global healthcare environment is filled with enormous
     challenges. It's become much more difficult in a lot of ways. But at the
     same time, it's filled with tremendous opportunities and scientific
     innovation, unmet medical needs are very, very important.

     And this combination will create a unique, premier, global pharmaceutical -
     biopharmaceutical company. The diversity of therapeutic areas that we'll be
     able to address, both in primary care and in specialty care, human health,
     animal health, consumer health, vaccines, biologics, small molecules,
     developing countries, developed countries. It will be a unique combination
     that will enable us - both of


     our companies and our people - to really advance their mission of using
     scientific innovation to help improve world health.
