CNBC Squawk CEO Call Transcript

Joe Kernan (host): … KLA-Tencor for about $10.6 billion dollars. It’s the latest in a string of M&A mergers in that sector as the demand for cheaper chips is pressuring companies to find a way to cut costs. Joining us now is the man behind the deal: Martin Anstice is president and CEO of Lam Research and he will head the combined company. We should also tell you that yesterday Lam reported adjusted earnings of $1.82, handily beating Street expectations by 11 cents. And now there’s one, I think. What happened, because there used to be, we always did Novellus, Lam Research…

Martin Anstice: … Applied Materials, KLA-Tencor, there you go, that’s the three.

JK: And now there’s Applied Materials and you.

MA: And us. Indeed.

JK: And you. And it’s made sense for years. Why did it finally happen?

MA: Well, as you know, it’s always a commentary on a number of things coming together: opportunity and the need from the customer in the marketplace and capability in the company. If I think about the need for the industry and this type of innovation and this type of consolidation, it’s hopefully pretty obvious to all. I mean, the exciting agendas of IoT and connectivity and sensors and electronics from a consumer perspective; memory storage, computation, tremendous demand roadmap in the next ten years. And from a capability point of view, in manufacturing, the complexity of technical roadmaps, Moore’s Law and economics, make the need very obvious. In terms of opportunity, both companies, Lam Research and KLA-Tencor, great performance in September, great guidance December. Both companies articulating a strong outlook for growth in calendar 16. Great platform. And you know, one of the important points, and you already set it up, is the Novellus transaction for Lam Research really demonstrated, I hope, an ability to integrate, to deliver the value and outperform. That was part one, and we’re scheduled for part two here. We’re excited about that. And opportunity and capability and need all have to come together. It takes time, and when it does it’s pretty special, and that was the reaction yesterday.

JK: New tech looks like a lot of the mergers are additive and they’re because of opportunities to expand a base or to add operations. A lot of mergers in old tech like Dell/EMC, and what you’re doing, it almost looks like it’s a way to rationalize operations, to put your two heads together and maybe get rid of overlapping operations, because times are tough, the decline of the PC, etc. Is that the wrong way?

MA: I think that’s the wrong way to think about our deal. We are actually not rivals, we are very complementary. We have zero product overlap. So from the perspective of anti-trust, regulatory approval complexity and perspectives, this is about as easy as they get. We obviously have to respect the process -

JK: Do you think people are listening? Do you worry? Is there going to be any question at all about this? Because the number of players is shrinking.

MA: We are very, very comfortable about this deal and about our ability to close as planned – we’ve articulated a mid-2016 objective. We respect clearly the regulatory review process. I’ve had an opportunity in the last 24 hours to dialogue myself personally and all through the team with customers, and their reaction generally is very positive. We are not rivals with KLA-Tencor. We are complementary, different product portfolio. This is about bringing process – we’re the guys who make it possible to make chips – with a company that’s in process control – which is all about making sure that the yields and the cost elements and the performance of those devices meet the specifications of the semiconductor industry. Process and process control is all about technology and productivity. It’s about solving the technical end challenges of physics and also the really important challenges of economics.

Ken Langone (guest host): Does this merger allow you – two things – number one, to rationalize costs? That’s something that’s not very important to me, because it’s essentially a one-time deal. The thing that I look to is, when you take two businesses and put them together, do you give your sales and marketing and your engineering people the opportunity to make 2+2=7 or 2+2=9? I think, to me, if there is going to be an economic validation to any combination, it comes about by the front end becoming more competitive and better.

MA: I think that is right on the money relative to the rationale for this transaction. This is about increasing strategic relevance, and strategic relevance has some element of cost rationalization. That is not the reason for doing this deal. The reason for doing this deal is to increase our ability to contribute to the success of our customers long term. It is exactly about bringing engineering communities together and developing more capable solutions that enable Moore’s Law extension and performance scaling. We all demand -

JK: So we don’t need as many CPUs, maybe, because of PCs, but we’re always going to need integrated circuits for the Internet of Things, for everything, right? We’re going to need chip-making equipment manufacturing…

MA: Yes, there’s a perpetual demand for devices, I mean integrated circuits…

JK: There are integrated circuits in all of them…

MA: …and that’s silicon…

JK: You have to go slow with me on this.

MA: and silicon is equipment, yes.

JK: So people talk about the decline of the PC, that shouldn’t necessarily spell the end of chip-making equipment.

MA: But I think one of the realities of our industry, if you look at the impact of the PC on the semiconductor industry in terms of demand and its impact on equipment, much less today than ever before. It is several years ago that the PC lost its prominence in terms of unit demands.

JK: Now you’ve got to make new things, mobile and all that stuff.

MA: Whole new range of demand.

KL: But you know, it’s no small feat. I want to go back to my point. When you’re going to put together engineering and research, NIH is alive and well.

MA: Yep.

KL: That’s a management challenge that I think people don’t have enough focus on, not only in the merged companies, but from the outside. Hey, my product - the first thing you get if you go to a drug company with a product, the research people are going to say to the boss, we don’t need that, we can do it here.

MA: I think one of the most fundamental value propositions of our company is the culture of our company and the values of our company. That’s competitive differentiation, and the value of bringing these teams together, getting them to work together in a way -

KL: But that’s supposing the other side is going to be cooperative and -

MA: Yes it does, and the good part of this deal, we’ve been working together for several years in a collaborative way with a great foundation, and we’ve done it before with Novellus. We’ll do it again.

JK: Thanks for coming here to talk about it, Martin. I appreciate it.

KL: Nice being with you, good luck. Make it happen.

MA: I will. Thank you.
