Mornings With Maria Bartiromo

December 17, 2015

[unofficial transcript]

[Maria Bartiromo, Host]: 2015 has been a record deal for mergers and acquisitions, headlined by the $160B deal between Pfizer and Allergan. The deal facing scrutiny over concerns Pfizer is moving its headquarter overseas, mostly because it wants a lower tax rate. Joining us right now in a Fox Business exclusive is Allergan CEO Brent Saunders. Brent great to have you on the program, thank you so much. And when you first sat down, I mentioned that Forbes magazine cover in which you were featured prominently. And it basically said you were the guy to watch in healthcare, and it turned out to be absolutely true, congratulations.

[Brent Saunders, Allergan CEO]: Thank you, its been a good year.

[Bartiromo]: When does this deal close?

[Saunders]: We think in the second half of 2016, perhaps on the earlier side, but we still have to get through the anti-trust regulators and go through the consult process with them to get a better sense of timing.

[Bartiromo]: Is this about taxes?

[Saunders]: It isn’t. Taxes are a component and I see everyone smiling, but it really is about creating a growth innovator in the pharmaceutical space. This will be the biggest biopharmaceutical company in the world, with the biggest R&D budget in the world. And being able to deliver medicines and cures to patients around the world. So when you look at what this industry is going through, the consolidation in this industry, this really powers up the new Pfizer to be the leader for the forseeable future in driving growth.

[Bartiromo]: Does it get any better than this? Mixing Viagra with Botox, the two hottest selling drugs.

[Geraldo Rivera, Co-host]: The stiffness champion.

[Saunders]: See I told you, a lot of jokes going around.

[Bartiromo]: The stiffness champion, I love it.

[Dagen McDowell, Co-host]: See me, I’m not saying anything.

[Rivera]: Where are you going to be headquartered?

[Saunders]: Our headquarters will be in Dublin, Ireland which is where Allergan is headquartered today.

[Rivera]: So it is a tax dodge basically.

[Saunders]: Well it isnt, we are not a mailbox in Ireland. We combined company will have roughly 5000 employees in Ireland. We will be one of the largest private employers in Ireland.


[Rivera]: I love Dublin, there’s two pubs for every three stores. You went there to beat U.S. taxes though.

[Bartiromo]: Well he is already there. Pfizer is an American company.

[Saunders]: Well to be fair, we are already there and Pfizer pays all of its U.S. taxes. Even after the deal closes, Pfizer will pay all its U.S. taxes on U.S. income.

[Rivera]: But isn’t that exactly what we’re all complaining about? You’re taking essentially an American company, you’re moving it to Ireland to beat U.S. taxes, but you’re still going to be doing business just as vibrantly in the U.S.

[McDowell]: That’s not their fault. That’s the fault of the politicians.

[Bartiromo]: We’re not all complaining about it.

[Gary Kaminsky, Co-host]: Brent is doing what the Pfizer shareholders – if you look at Pfizer stock over the last five years – Pfizer shareholders are crying for this because they want to see a higher return.

[Rivera]: This is what Trump is saying. That we should have a tax code that discourages exactly this move. With all due respect, I would do – if I were him, I would do the same thing, but the problem is from the U.S. point of view is that our Treasury is going to be denied x-amount of billions of dollars and I think that’s…

[Bartiromo]: And that’s their fault because they won’t do tax reform.

[Saunders]: Let me just say – one point in this debate which I think is very important for people to understand is that, when this deal closes and Pfizer becomes Pfizer PLC headquartered in Dublin, we will have 40,000 employees in the U.S., we will spend the vast majority of our $9 billion of R&D in the United States, and we won’t avoid any U.S. taxes. What we will not have to do is pay double tax on foreign earnings back in the United States.

[Bartiromo]: And why should you pay double tax?

[Saunders]: In fact no one does. The hoard the cash offshore so we’re not giving upanything

[McDowell]: If you get tax reform here, if it means better taxation for you, will you move your headquarters back to the United States?

[Saunders]: I don’t think people…well…we’re already there.

[Bartiromo]: Allergan is an Ireland-based company.

McDowell: If you get tax reform here, would you consider moving the HQ here?

[Saunders]: We’d have to look at the situation at the time. Look, we’re very happy to be in Ireland.

Ireland is a great country. We are a very large employer and supporter of the United States.

[Kaminsky]: Listen it’s a public company with public shareholders and he’s gotta do what’s right for the public shareholders.


[Bartiromo]: I’m with you 100%

[Kaminsky]: Let me turn a little bit here and just ask you , you know 9 out of 10, history says 9 out of 10 of mergers don’t add value. You happen to be very fortunate that as a CEO you’ve been in the 1 out of 10, you’ve created a lot of value. Part of doing deals is borrowing money and interest rates, the Fed made this move yesterday, we’ve talked about it, you’re a dealmaker, is this going to have an impact on what deals can be done now in the future with the higher cost of capital?

[Saunders]: I think, to be fair, it could, but going up .25 basis point is still historically incredibly low interest rates and cost of capital. I think for investment grade credit it doesn’t matter. If you’re a high investment grade credit it doesn’t matter, as you start to move down into the higher yield credit companies, perhaps it starts to matter more. And the lower down you go the harder it is because access to capital will become a problem not just cost of capital. So companies like Allergan and companies like Pfizer with very strong credit, we’re fine.

[Bartiromo]: What’s in the pipeline tell us about the pipeline tell us where growth comes from once you are the largest pharmaceutical company in the world.

[Saunders]: Yes, we have a lot of exciting opportunities in the pipeline. The ones I get most excited about are the ones in oncology, particularly immuno-oncology, where we’re looking at a lot of products that can be game changing for people suffering with cancer, potentially even cures over time

[Bartiromo]: Where specifically the cancer, what kind of cancers.

[Saunders]: Well, Pfizer is looking at combinations and a variety of different indications some very tough to treat cancers across the board. They’re looking at, I would say, perhaps close to a dozen different areas and some hard to treat ones. We have some game changing R&D in depression where really there hasn’t been any new modalities or new ways of treating depression in a long time. We have some new ones in diabetic gastroparesis – there has been a new treatment in 30 years. We have some new areas in our aesthetic portfolio, as well. It is a really exciting time our portfolio combined in about 100 mid to late stage programs.

[Rivera]: Are you happy that creepy guy got charged with fraud? That jacked the price up to 700 bucks.

[Saunders]: Yeah I read he got arrested this morning, look I mean I think…

[Rivera]: How do you feel about people who do that kinda stuff? That’s the market he has got shareholders.

[Saunders]: I think the collateral damage is what is problematic, right? There are always bad actors and people pushing the limit in every industry: banking, pharmaceuticals, telecommunications, you name it. What happens in our industry because we have a social contract to invest in R&D, to solve for unmet need, to cure people of disease. You get these guys who trade on the outskirts that really do…

[Rivera]: Make you all look bad.

[Saunders]: Right. And you get collateral damage, you get the politicians that try to cast a wide stone across the entire industry, but look 99% of this industry comes to work everyday trying to do good things and to cure disease and to solve healthcare pricing.


[Rivera]: There must be something else you can stiffen up.

[Bartiromo]: When you see a profiteer, that puts a face on the whole industry, unfortunately. Alright, so when you get these two companies together and you said it probably middle of next year, is there enough overlap that you will see cuts in terms of jobs? Where are the synergies and should we expect cuts?

[Saunders]: So we announced about $2 billion of synergies over three years – about two thirds of that will come from SG&A and so we will really be looking at the overlap of let’s say a finance function or an IT function or an HR function, a little bit in the sales area, but not much there. And really over the period of time a lot of that may come from attrition, so this isn’t about deep cost cutting this is really about growth.

[Kaminsky]: Organic revenue growth post closure is what?

[Saunders]: So we are gonna aspire over the next two three years to get to high single digit top-line growth.

[Bartiromo]: High single-digits revenue growth?

[Saunders]: On a big company you are talking about a company with roughly let’s say $65 billion in sales.

[Bartiromo]: That’s terrific. Brent, really nice to have you on the program

[Saunders]: Yeah, thanks for having me.
