Excerpt from Earnings Presentation

Excerpt from Earnings Call

Edward D. Breen

Executive Chairman & CEO

We also made nice progress on our third priority, bolstering our already strong balance sheet. As we discussed the last quarter, we launched a successful $2 billion bond offering, which will be used to satisfy the long-term debt maturity that come due in November of this year and extended and upsized our liquidity facility. Looking ahead, we plan on using $5 billion of special cash payment associated with the N&B and IFF deal to pay down debt, which will leave us in a very favorable position with no long-term debt maturities until the end of 2023…..

Slide 7 highlights the progress we have made since announcing the N&B and IFF transaction in mid-December. During the quarter, we completed additional key milestones. It May, DuPont, N&B and IFF filed the respective initial registration statements and are advancing the review process with the SEC. IFF and DuPont also named the Executive Committee of a future combined company, which will include key DuPont N&B senior leaders. In addition, the company has announced 2 independent DuPont appointees to the Board of Directors of the future combined company. We have made meaningful progress regarding regulatory approval, we cleared the U.S. process in March and have since received approval in China, Serbia and Colombia. The clearance processes and the remaining required jurisdictions are well

underway.

Earlier this week, IFF filed its definitive proxy related to the IFF shareholder approval of the transaction. The IFF shareholder meeting is set to take place on August 27. I remain excited about this combination and the tremendous opportunity for growth and greater innovation as the businesses come together. The teams are energized and all the critical milestones remain on track for a first quarter 2021 closing.

BofA Merrill Lynch, Research Division

I was curious to hear what fraction of your staffing at headquarters and in R&D during the quarter were working remotely. And do you see any impact on the R&D productivity from that challenge? And with respect to headquarter staffing, just curious about what you’ve learned from this. You’ve obviously accomplished everything the headquarters needs to do with that staffing working remotely. Where do you think that goes down the road. Is that a lot of that staffing remain remote? Or is that kind of what you’re talking about changing the locations or figuring out another way of housing all of that staffing?

Edward D. Breen

Executive Chairman & CEO

Yes. It’s a great question….

One of the things that I think every CEO is seeing in this environment, though, back to your point about the corporate office and many of our other offices, we’ve been able to really work very well remotely. And by way, remember, DuPont is going through a massive deal with IFF and N&B and all the integration work and separation and car financials and tax work and we’re right on schedule with it despite most of the people working remotely. So we really -- we’ve put a team together, and we’re really looking at how do we handle our office footprint around the globe going forward….

Michael Joseph Sison

Wells Fargo Securities, LLC, Research Division

In the Nutrition & Biosciences, you drove 240 basis points of margin improvement. What drove that improvement?

And beyond 2020, Ed, given you’ll be on the IFF, what do you think the normalized growth rate for this business could be? And remind us how you think IFF combination can support that growth?

Lori D. Koch

Executive VP & CFO

Yes. So maybe I can hit the margin piece, first. So we did drive really nice margin lift in N&B, and a lot of it was driven just by favorable mix. And so we had mentioned that our probiotics were up about 30%. That’s definitely the highest margin piece of the portfolio. So we really had nice improvement there. And also cost actions helps with the margin lift. So N&B would have shared in a portion of $130 million of cost reductions that we saw in the quarter.

Edward D. Breen

Executive Chairman & CEO

Yes. And just, by the way, on the combo, look, a couple of key principles. We’re going to have pretty massive R&D capability in the combined company. So we’re not doing any cutting there. Most of our synergy work as it is DuPont is really going to be on the G&A side. So we’re going to have really nice scale to be launching consistently new products into the markets. We’ve had great feedback from customers on our ability to do a lot of application development work with them with the extensive portfolio we’re going to have. So I feel very bullish on that. And as you can see, generally, as an industry, it just holds up very, very well. I think Lori mentioned this in her prepared remarks, 85% of the portfolio is really food and beverage-centric, grew organically 5% in the quarter. And the piece that drug it down to 1% in aggregate was really industrial end markets that we play in. So we’ll have to look at that as we move forward. But it’s just a consistent industry.

I would also point out, I think I said this on the last earnings call, the multiple that IFF trade at and, by the way, the IFF value or the N&B value is basically still about where we announced the deal at, which is $26 billion of value for a DuPont shareholder and IFF’s multiple still sits 400 to 500 basis points below the top, what I’d call, the top few players in the industry. So I think we, as a combo, we proved success rolling out the new company. There’s great margin expansion capability just with the IFF share price and

clearly, the #1 position that we’re going to have. Again, we’ve got to come out elegantly and integrate the company well but that opportunity is there. And in this case, I truly believe we have the revenue synergies we’ve talked about with what we can offer to a customer. One of the areas — it’s probably — it’s still a small business, but one of the areas really growing for us right now is the meatless meat market business and I think we had a chart out when we announced the deal. IFF has 4 or 5 products that sell into that industry. DuPont has 4 or 5 products that sell into that industry. So our ability to innovate, just use that as one example, innovate in that industry as it moves forward, is just way more significant than anybody else. So I think it’s going to be a really awesome company when we get going on it, and hope February 1 is our date to consummate the merger next year. Again, and as I think Lori said, the vote — the shareholder vote is on August 27. So another month from now, and that will be done.

Any updated thoughts on how you’ll distribute the new IFF shares. You’re giving yourself a lot of flexibility between a spin-off and split off here. Are you tilting towards one versus the other?

Edward D. Breen

Executive Chairman & CEO

Well, I can’t say yet. We’ll make that decision as we get later into the fall. I mean, I’ve always just done a spin-off but I don’t want to put a leaning on it right now. It just depends what the numbers look like when we get there. But look, I think the good news overall, John, I mean, the shareholder votes happening in a month, the deal is definitely happening. I know earlier in the year, people were curious, is this thing going to stick and all that with everything going on. So the deal is in great shape from that standpoint. And again, we’ll see where we’re trading at, what’s going on at the time, and we’ll make a decision then. And you just can’t make it right now because you don’t know the facts.

John Ezekiel E. Roberts

UBS Investment Bank, Research Division

And then could you give us an update on the ethanol enzyme in the bioside businesses, which are the weaker areas within N&B recently?

Lori D. Koch

Executive VP & CFO

Yes. So that was within the 15% of the portfolio that we had noted that was weak in N&B. So that portion of the portfolio, along with microbial control, was down significantly in the quarter. As we look to the back half, we would think you would see kind of a flattish in the second half, but we’ll see how the market continues to play out.
