PRESENTATION
Nigel Edward Coe—Morgan Stanley, Research Division—MD
Great. So I think we’ll — we can start. So if you can sit on your seats, seems possible. We’ll resume with Akhil Johri, CFO of UTX. I think just given the time constraints that maybe we can start. You’ve got some slides, Akhil?
Akhil Johri—United Technologies Corporation—CFO and EVP
Sure. Thanks, Nigel. Good morning, everyone. Some exciting location. Exciting things going on with UTC. But before we start, just the usual customary cautionary statement. Things that I say today, the presentation includes forward-looking statements, which are filled with uncertainty, as you all know. There is risk factors outlined also in the presentation, but also on our SEC filings both for us and for Rockwell Collins, which is going to be part of UTC. So for those of you who might have missed the announcement last week, UTC is looking to acquire Rockwell Collins. It’s a great deal which will make UTC’s aerospace assets much stronger. The capabilities that Rockwell Collins has in software design, in data integration, in communications network, combined with the sensors technology, the power generation and distribution capabilities that UTC has will create opportunities to provide great differentiated services for the airline customers, particularly in the preventive maintenance space and also in the future of aircraft as things become more digital, more connected, more electric, more intelligent. The capabilities together will offer a lot of opportunities there. For me, a lot has been said about the strategic benefits of the 2 coming together. For me, the 2 things which jump out at me is, one, Rockwell Collins has a pretty diverse customer base. It’s not just — they don’t just supply to their airframers. They supply directly to the airlines who buy furnished equipment. They have a pretty robust defense portfolio. And point number two, the cash profile of UTC Aerospace businesses will improve with the addition of Rockwell Collins, particularly through the investment cycles. As you know, the engine company needs a lot of investments. And as we go through a phase of new aircraft development, which will come at some point in the future, Rockwell Collins will be able to better balance that to some extent because their capital, their development needs are not as capital-intensive as it is on our current assets. So those 2 stand out for me.
We’re looking for synergies of about $500 million, at least $500 million by year 4. $400 million of that are incremental. About $100 million of that is the synergies that Rockwell was counting for from B/E post our expected close. We are also looking at an IRR above our cost of capital, and that is not a low ball cost of capital number, but it is 8%, is that is what we’ve used in here. I would tell you our assumptions are relatively conservative in the model. We have no revenue synergies, particularly in the aftermarket side, which can come with good margins and good cash flow included. We have also kept a very low terminal value number. It’s only 2.5% growth we’ve assumed for terminal value in our modeling, which is relatively low, given the robust aerospace sector outlook that we have. So I have high confidence that we’ll be able to do better than the returns that we have articulated thus far. We’ve done that in Goodrich, and we hope to repeat that again here.
Also a point of confusion, we will — the transaction will be accretive in 2019 calendar year. That’s assuming we can close in Q3 — relatively early in Q3. So for a July 1 close, we should be able to see an accretion in 2019 calendar year, and that is after normal intangibles amortization and the effect — negative effect of suspending share buybacks. So pretty decent transaction as it’s accretive in the second — in the first calendar year itself — first full calendar year.
Now some of the more interesting comments I’ve heard over the last week or so has been we are spending — UTC is spending $30 billion of your money to obfuscate problems in other businesses. Like many of you, I love conspiracy theories, but that’s not what this is about.

SEPTEMBER 14, 2017 / 3:10PM, UTX - United Technologies Corp at Morgan Stanley Laguna Conference

Nigel Edward Coe—Morgan Stanley, Research Division—MD
Okay. So I think we spent a good time talking 2018. Maybe it’s a good time to maybe transition to maybe talk about the Collins transaction. And you mentioned that kind of the biggest concern was that this is a masquerade for problems elsewhere in the portfolio. What other kind of objections are you hearing on the transaction from investors?
Akhil Johri—United Technologies Corporation—CFO and EVP
Well, one is clearly that people feel the returns are lower than what they would have expected, what we have publicly stated. There’s no denying. We have talked about doing transactions which hit IRRs of over 10%. But I can assure you, I think we had a long debate about that. Rockwell Collins is one of those properties that you rarely get a chance for — to acquire and to make part of the portfolio. If there was one transaction in the world for which I was willing to, and I think our board and Greg were willing to take a little hit, right, on our returns expectations, it is Rockwell. I would have hated to be in this room 5 years from now when somebody would have said, “You had a chance to acquire Rockwell Collins, and you didn’t?” I mean, it’s such a game-changing opportunity for the UTC Aerospace businesses for multiple reasons, that being slightly lower than our 10% --it’s still above cost of capital, so it’s not destroying value in any way. It will still be accretive. It will still be adding value to the shareholders in the long term, but it’s not just that revenue synergies will come in the future when new aircraft, and that’s 10 years away, so nobody cares about it, but it is also opportunities in the aftermarket space where we can offer additional opportunities utilizing Rockwell’s surplus capabilities, for example. They have a great surplus capability, which we don’t have. We are trying to build that in UTAS. We have opportunities to take advantage of that. We could offer preventive maintenance solutions to airlines with a combination of the intelligence that our sensors gather plus the software and the data integration capabilities that Rockwell has to make it less expensive for airlines to fly what they do today. So there are some nearer-term opportunities. None of that is baked into our returns calculation because we tend to be very strict on ourselves by saying we only count what is real and tangible, which is the cost synergies. Other things will come in and add. So I’m hopeful. I’m relatively confident that we’ll see better returns than what we are seeing today. We got beat up for that, but that’s okay. It’s still something that we think it’s absolutely — I’d rather have Rockwell Collins in the portfolio than not.
Nigel Edward Coe—Morgan Stanley, Research Division—MD
One thing we hear is that the $400 million of cost savings since the synergy. So the $500 million, the $400 million plus $100 million, at some level gets passed back to Boeing and the OEMs. And the example we gave is Goodrich. Obviously you did the $350 million to $400 million of cost saves on Goodrich, yet margins are still pretty flat to where they were. So how do you overcome that concern?
Akhil Johri—United Technologies Corporation—CFO and EVP
That’s an interesting observation, because I’m surprised very many intelligent people actually come up with that observation. But if you go back and look at the margins for Goodrich, adjusted for accounting conformity, they were like 12%, 12.5%. They were not the 16% that everybody thought Goodrich was because they had a different accounting, right? So when you conform to UTC accounting, the combined margins had gone down. We took a larger business with lower margins, combined with Hamilton Sundstrand of 16%, and over the last few years, we’ve actually grown the margins. So synergies are in the margin. You can’t just look at the reported margins of the 2 businesses before accounting conformity and say that they didn’t add any value. That’s absolutely untrue, right? We have seen the benefit of synergies come through in the P&L. And what is happening at UTAS now is offsetting of the adverse mix that, before me, David Joyce, talked about, right? I mean, everybody is experiencing that. So UTAS is actually in the same situation that the GE Aviation business talks about, being able to hold margins through this ramp, which is pretty remarkable. So I think it’s creditable what you guys have been doing.
Nigel Edward Coe—Morgan Stanley, Research Division—MD
That’s a great point. It’s a great point. And then obviously, have to answer the question about Boeing’s longer-term ambitions in the aftermarkets. And [Mellencamp] was here yesterday talking about the $50 billion opportunity on services. How do you overcome that concern?
Akhil Johri—United Technologies Corporation—CFO and EVP
Well, the reality is that aftermarket comes in a couple of ways, right? One is, you can play the role of somebody who takes the order and provides — and then does the services part of the aftermarket, okay? So the second part, which is the greater-value part, is if you have parts that you supply. So unless Boeing starts to make all the parts that go into an aircraft, they will have to buy the parts from somebody. And in fact, if we have differentiated technology and parts that we produce which nobody else does which are specified on the aircraft, they will have to buy the parts

SEPTEMBER 14, 2017 / 3:10PM, UTX - United Technologies Corp at Morgan Stanley Laguna Conference
from us, right? So to me, while there may be a little bit of concern from a margin perspective, it may be that the — in the universe of accounting, you will have the same sales being counted twice. We sell it to Boeing instead of to airlines, and Boeing sells it on to the airlines maybe, right? So in the universe, you can have one plus one becoming — one becoming two. But in reality, it — I don’t see that as a huge negative to our aftermarket business. The key for us is to continue to drive differentiated technology and offer IP-based products that help airlines run more effectively and better as long as we keep doing that and stay away from commoditizing ourselves, right? The reason why we lost the landing gear business, the 777 landing gear business, was because it was a build-to-print commodity business. So to the extent we invest in our R&D to generate IP-based products, I think we can protect our aftermarket a little bit better than what people are thinking. * * *
