INTERVIEWEE

  

AUDIO

Paul Bisaro,

Executive Chairman

   Things sometimes present themselves that, that you can’t pass up. And, when Brent and I first got together and first met for dinner, it was pretty clear, fairly quickly, that we had something to talk about.


   The, the two companies were very synergistic and very similar in the way they approach things. Forest, albeit more brand, but us more generic, but together we could really create something special.

Brent Saunders,

CEO and President

  

When we did start speaking, we knew that we had something that strategically made sense and that, that would create a one plus one equals three situation.

 

But, then as we started doing some of this pre-integration activity, I think the excitement level’s even gone higher on, on the possibilities in what this company can do.

Bill Meury,

Executive Vice President

Commercial, North

American Brands

   You know, I’ve heard the term new breed of pharmaceutical company and perhaps it’s a lofty term, but if you think about it, it’s not a generic only company, it’s not a branded specialty only company, and it’s a pretty powerful organization.

Brent

   To have a best in class generics business with a best in class specialty business to have a geographic footprint of 60 plus countries and all the optionality we have for future growth. Organic growth, M&A, business development, licensing, R&D, branded generic R&D, a billion dollar investment.

Bob Stewart,

Chief Operating Officer

  

I’m really excited about the opportunity to bring the R&D and operations group closer together. The value that we can unlock from that I think, is incredible.

 

When I think about what we can do between the R&D organization and operations together, we’re not only going to be able to supply products and deliver products for patients and customers today, we’re going to be able to develop products and continue serving patient needs for the future. So we’re really combining the best of both networks.

Bill

   Personally, for me, I’ll be overseeing a branded division, but I’m looking forward to learning a lot more about the generic side of the business, I’m looking forward to learning a lot more about operating a business outside the United States, Brent, you have a lot of experience with that, others at the table do.


   I’m also excited about managing a terrific product line. It’s a product driven industry. If you have products, you thrive. If you don’t, you don’t live very long. And that’s what excites me personally and professionally about being at Actavis.

David Buchen,

Executive Vice President

Commercial, North

American Generics &

International

  

I could not be happier with my new role. I’m going to heading up the North American Generics and, and international sales effort and this is a real opportunity for me to break out.

 

I think I’ve always seen myself as a bit of a frustrated commercial guy, leaning more toward the commercial than the legal and this, this will be a real opportunity for me. I, I will say that I’d be naïve to think that I can do this without a tremendous amount of support from the great team that I already will be inheriting and there are some fantastic people here in the United States as well as all around the world, where I’m going to rely on their support to make sure that we’re a complete success.

Brent

   As I’ve gotten to, to meet the people of Forest over the last almost year and, and the people at Actavis over the last few months, it’s just an incredibly impressive group of people, to watch them do great things, to help build their careers and help them develop, is something I just take an immense pride and joy in, in watching happen and, and so, I’m very excited to see that happen in the combination.

Paul

   It doesn’t really, sort of, matter, at least I don’t think, it matters what size you are, it matters what the, how you execute and how you perform and how you do all the things you got to do. We went from a very small organization with a few opportunities to a very large organization with a lot of opportunities. And that means more people have to execute and more people have to perform and we get to watch those people really move up to a new level and if everybody does what I think they can do, this new organization will perform at a very high level.


Brent

   And I view my role as, really, one about people. People make great companies and my job is to make sure that we retain, develop and recruit the best people possible to make sure we can take advantage of all the wonderful opportunities we have as a combined company.

Paul

   I’m very excited that Brent is the new leader of the company and I’m here to support that role and I want to be a big support to that role and you guys all have big jobs and I’m again here to help support you.

Brent

   One of the main reasons I accepted this wonderful role and why I’m so excited about it, is, you know, your coaching, your mentoring, your vision and your strategy are, I think, are critical to our future success and, you and I have such an easy relationship and we work so well together, I think, as a team we’ve seen that already start to blossom and I can’t imagine where it’s going to go over time it’s just incredibly exciting to me.

Paul

   Focusing on our assets and our people is key and of course both of our companies both Forest and Actavis have been successful doing one thing and doing it very well and that’s execution. We’ve executed on everything we said we were going to do, and our people have worked very very hard to make sure that execution happens and the good part is that I get to still be part of this.

Brent

   Ultimately, where we’re going is to be an exceptional company, right? To be the best at what we do. And we’ve got such a strong foothold already, in being a leader in generics and being a leader in specialty pharma. It’s now putting that all together, growing in our geographic footprint, investing in our business, doing our R&D, continuing to be the best manufacturer of high quality, reliable supply and great things will continue to happen.
