EXCERPT

John Ahn - J.P. Morgan - Okay, great. Let’s see, so I guess when we start talking about Enterprise Computing, you know, obviously the big news, the last time around was your acquisition of PLX -

Ted Tewksbury - Integrated Device Technology, Inc. - President & CEO Uh-huh.

John Ahn - You know - makes you a de facto leader in PCI Express, basically. I just kind of wanted to get your perspective on, you know, what was the thinking process, both from a technology advantage standpoint, as well as from a financial standpoint, if you could kind of walk us through some of that thought process?

Ted Tewksbury - Integrated Device Technology, Inc. - President & CEO Yeah, great question. We’ve been getting a lot of questions about PLX since the announcement. You know, from a strategic point of view, what this does is it enables us to expand our data center interconnect solutions in one of our core markets, which is Enterprise Computing. And what’s happening there is, of course - of course, it expands our existing leadership in PCI Express, but more important, to understand the strategic logic you’ve got to understand that there’s a major paradigm shift that’s happening in data centers today, and that is the deployment of solid state drives.

And there are a number of different usage models, there’s direct attached, SSDs that are used in the server as a cache in order to accelerate the processing in cloud computing data centers. You’ve also got standalone centralized storage boxes that use SSD arrays that are connected through PCI Express switches to the CPUs. Those boxes, in turn, are connected through storage area networks to the servers. And then you’ve got top of the rack appliances that use the same kind of architecture. All of those architectures use an array of SSDs. The interfaces on those SSDs are moving from traditional SAS and SATA to PCI Express, in order to provide higher throughput, lower latency, lower power, and so forth. And then those arrays connect up to one or more CPUs through PCI Express switches. So we’ve talked a lot at our Analyst Day, as well as on our earnings call, about the investments that we’ve been making in these SSD Flash Memory Controllers with PCI Express interfaces. IDT today is actually the only company in the world that has a fully integrated enterprise class flash memory controller with a native PCI Express interface. And what’s happening here is that those SSD arrays are now driving an expansion of the PCI Express switch market.


John Ahn - Uh-huh.

Ted Tewksbury - Integrated Device Technology, Inc. - President & CEO And that really is one of the primary reasons for the PLX acquisition, from a strategic point of view; it enables IDT to now offer our customers a complete system-level solution, so you can think of it as we own both ends of the wire now, we own the PCI Express interface to the SSD, and we also own the switch. And that enables us to offer our customers an overall solution - and, again, that’s back to our original strategy, which is offer system-level solutions to our customers. We can offer them an SSD solution that’s higher performance, lower cost, lower power, and also that enables advanced features; think, for example, of hot plug ability, or hot removal of SSDs from the system. In order to implement those kinds of features, or to implement RAID systems, for example, you have to be able to optimize the switches and the SSD interfaces to work together and be interoperable. And so that’s what this acquisition gives us, strategically. It expands our market and it enables us to offer complete system solutions to our customers.

John Ahn - Okay. Can you also maybe elaborate a little bit more on the financial aspects of it, as well? I mean, you paid $7.00 per share, you talked about some pretty good synergies, actually in excess of $35 million in synergy - cost synergies -

Ted Tewksbury - Integrated Device Technology, Inc. - President & CEO Yeah.

John Ahn - So if you can just kind of talk about maybe some of the financial rationale?

Ted Tewksbury - Integrated Device Technology, Inc. - President & CEO Yeah. So the financial rationale, every acquisition we do, we look at accretion of the acquisition relative to what we could get with a stock buyback. In this case, with the synergies, the acquisition is comparable to what we would get with a stock buyback; however, what the acquisition gives us is all the strategic benefits that I just described. It gives us the scale that we need to accelerate our progress towards our target operating model and it gives us some very nice accretion. We talked about the accretion during the earnings call. Basically, the way it lays out is that, today, if you look at PLX’s pro forma results for the past four quarters, they did about $113 million in revenue at a 57 percent gross margin, which is comparable to IDT. Their OpEx is around $74 million, and therefore they’re incurring about a $10 million loss per year. We’ve identified synergies in excess of $35 million to $36 million, which would be realized, number one, by selling or divesting the 10 Gig Ethernet effort, which is the Teranetics Group, which is about $17 million; $18 million of annual R&D spend. And then there’s also synergies resulting from public company costs, duplicative selling costs, G&A, and so forth. If we roll that in, that’s another $17 million worth of synergy savings. In addition to that, we have about $2 million or so of [clog] savings, which result from volume pricing that we would be able to achieve with foundries, as well as taking their test operations and some of their other back-end operations, and pulling it into our Malaysia test facility. So you roll all that up, you’re at the $35 million to $36 million range in synergies, which turns a $10 million a year loss into a $26 million a year operating profit. And we think that those numbers are relatively conservative. Also, there are tax benefits.


PLX is a U.S. company and, when we integrate them into our international tax structure, and we take advantage of about $150 million of combined NOLs, some of those earnings - well, basically all of those earnings - are shielded on a cash tax basis and that increases the EPS even more than what we’ve talked about. So, as I mentioned, we think those are conservative numbers; we think we can potentially do better. We also think that the integration will be relatively straight forward. We’ve had a lot of experience with these kinds of integrations. Tundra Semiconductor is a great example where we had a plan to achieve 60% synergies on their OpEx and we achieved that within one quarter, and we actually did better than our plan of 60 percent, and that was with a much more complicated and more geographically distributed company. In this case, PLX is right up the road from us in Sunnyvale, 15 miles away, comparable products, good cultural match, same - or complementary customers. And the company will basically slot right into our existing Enterprise Computing Division and should be a relatively straightforward integration, so it should be relatively easy to achieve those synergies. If we’re able to close the deal in June - which is maybe a little bit aggressive but, by the end of June, if we can get it done, we could realize most of the synergies by September and be accretive by the December quarter.
