ED BREEN HOSTS CEO TOWN HALL

DuPont Chair & CEO Discusses 2016 Progress and the Company’s Historic “Journey to Three”

Chair and CEO Ed Breen held his first global Town Hall meetings on Thursday, April 28.  Ed used the opportunity to touch on a variety of topics that are top of mind for colleagues throughout the company, providing his perspectives on … the company’s historic path toward its intended merger with Dow.

An Update on Our Journey to Three

His focus then turned to our path ahead — and the topic on everyone’s minds — our progress toward the proposed merger with Dow followed by our intention to separate into three highly focused, industry leading independent companies.

First, Ed underscored how important this merger is to DuPont’s future.  “We wanted to control our own destiny...”

By first combining forces with Dow and its portfolio of complementary businesses, the three intended spinoff companies will be built from positions of strength. He said, “We’re going to have a world-leading Material Science company… and one of the leading Specialty Products companies.  And we will be the leading Ag company.”

The resulting independent companies each will continue DuPont and Dow’s legacies as two of the leading science and innovation enterprises in the world.

Shareholders of both companies still have to approve the merger, and those votes are expected to occur this summer. Officers of the merged company also will  be named, including the chief operating officers for the three divisions—Agriculture, Material Science and Specialty Products.

After the merger is complete (the transaction is expected to close in the second half of 2016), Ed said, “We will start running as three divisions… but still under the one umbrella.” He estimates that the spins will occur no later than 18 to 24 months after the closing of the merger. During that time, DowDuPont will report financial performance for the overall company, as well as for the three divisions.

Some excerpts from Ed’s responses to colleague questions:

·      On retaining talent: “This is the tough phase right now. I promise you the excitement is going to build. When you get to MergeCo [after close], things really change; people can see the opportunity and the growth. As soon as we can get clarity for everyone, the more people can calm down and say, ‘I get this.’  That’s when people can really say, ‘I want to be here.’”

Transcript of CLIP #2: Our Path Ahead — Merger with Dow

That really tees us up now for what’s next. And, what’s next is the announcement we have, I’d say pretty historic announcement by the way. It’s a huge deal, it’s a complex deal. There’s nothing easy about this. I will tell you though we will get through it, and the sun will be very good on the other side when we come through it. We are creating three world class companies as we go through this process and we wanted to control our own destiny and this allows us to control our destiny…to still stay as one of the leading innovation platforms in the world. In fact we’re going to have more hours spent on innovation once we accomplish this, in all our sets of businesses than we had as DuPont alone.

So we’re going to have a world leading Material Science company, one of the leading, not the biggest, but one of the leading Specialty Products companies and we will be the leading Ag Company and when we get done with that they will have significant R&D and real focus to our end customers.

So, kinda let me talk about the path ahead here. There are hundreds of you in the company already working on the merger with Dow but many of you are not and some of you are hearing rumors of things that are true and probably things that aren’t true, but what we have set up is a steering committee and you could see the names of some of the senior people from both companies and we meet regularly as a team. In fact we’re meeting tomorrow afternoon starting at three o’clock. So it is going to be a long week. So, anyway, that’s the team that meets and that team is really responsible at the top to get this thing organized right, move it along as fast as we can, speed is important, we don’t wanna make mistakes, but speed’s important so everyone, again, can get to the end state as fast as we can, and, and any really big tough decisions so they don’t keep moving around in the organizations will go up to the steering committee to make a final resolution on.

What we set up though a few weeks back or a month ago was the joint integration office and that’s staffed with a lot of people from both companies, Rick Olson — most of you know Rick — is leading that steering committee. It’s a lot of work, but you can see the core teams underneath this, how we’re organized, so we have our master planning team and you could see for design and integration to get us ready for day one when we merge the companies together. Obviously we have a big thing here that we’ve announced to our investor base and everyone. We have to get the value capture. We do have cost synergies, we have a lot of great revenue synergies which are really exciting by putting these companies together and, oh you have this, we have this, well we could do this, and so we’ve already identified, and I’m sure as all of you get involved, we’re going to identify way more revenue opportunities here and, and, new routes to markets and things that can leverage both companies, so there’ll be a lot more work done there.

[flash transition]

So, then what happens, and let me just walk you through this a little bit. We’re bringing the two companies together, on the left we have them, and what we do is we will bring them together under MergeCo with us and that team I told you will be announced very shortly, running the company at the senior level. It’s gonna be a very lean corporate structure at the very top because what we’re trying to accomplish here is push down the responsibilities into the three divisions because they’re gonna end up being the three public companies and that’s where all the responsibility should lie at some point.

So, what we will do is bring them together under MergeCo so the Ag business from Dow will come in, our Ag business, but they’ll still be kinda at least day one because we’re not allowed legally to do this ahead of time, they’ll just all be brought under the same umbrella.

Then what we will do is we will very quickly move to integrating them together, so Dow Ag, our Ag together as a division. Specialty at their end, our end together as a business. Our business is going over to performance materials and then create material company and we will do that as quickly as we can. So that’s when some things will maybe feel a little different for you from the standpoint if you’re a person, or you’re a corporate person here, you’ll be a corporate person at one of the companies and we will start running as three independent companies but they’re still under the one umbrella so they’re basically divisions, but we will run that way as quickly as we can. We want to be able to communicate very quickly with our customers. We don’t want to miss a beat as we go through this process….

So, again, this is a lot. I don’t wanna downplay it and it is a lot of change. Again, we will communicate with you as quickly as we can on everything but that’s kinda the path that we see and the journey we see going forward.
