Thanks, Steve. Welcome, everyone, and thanks for joining us today. I'll begin today's call with an overview of our fiscal third quarter results for 2017, and then turn the call over to Bob McMullan, our CFO, who will review our financial performance in further detail. I'll then conclude today's prepared comments by providing a summary of our execution and key highlights during the quarter, and guidance for the fiscal fourth quarter of 2017. Our third quarter financial results came in at the lower end of our guidance range, while we had anticipated soft demand in segments like PON and China-based Metro/Long-Haul, both were significantly weaker than prior expectations. Partially offsetting that weakness, we have solid performance in our A&D and multi-market businesses along with breakout growth again in Data Centers. Last quarter we began highlighting a weakening environment for Network infrastructure in China, which impacted not only our business, but the entire Optical supply chain. Despite those major headwinds, we were able to deliver 5% sequential growth. Looking to Q4, demand in China remains very weak as Chinese provincial deployments continue to push out, and carriers wind down spending in 2.5G PON in anticipation of 10G. These are major factors shaping Q4 guidance. As diversified high-performance analog provider, with broad exposure to numerous end markets and geographies, there are always puts and takes in our business. For the third quarter, these roughly balanced out. However, in the fourth quarter, the degree of weakness we're seeing in China simply cannot be offset by the ramp of other growth drivers in the near term. Despite these short-term challenges, we remain highly confident that our growth strategy remains on track. We expect these cyclical headwinds to turn into tailwinds in fiscal 2018 and our additional growth drivers will layer in on top. So, over to the numbers. Revenue for our fiscal third quarter came in at $194.6 million within our prior guidance range, up 5% sequentially and 37% year-on-year. Excluding the contribution from AppliedMicro and despite Optical being down 16%, we grew 7% organically on a year-over-year basis. Adjusted gross margin was 58.5%, with adjusted earnings coming in at $0.67 per diluted share. By end market, Networks was up sequentially, growing 43.5% year-on-year. Multi-market grew sequentially and was up 17.5% year-on-year. Aerospace & Defense was slightly down sequentially, but still grew 18.3% year-on-year. Now, let me turn it over to Bob to review our fiscal third quarter financials in more detail.

Thank you, John. And good afternoon, everyone. I will review MACOM's fiscal third quarter results and financial position, provide an update on our planned sale of the AppliedMicro Compute business and with commentary around our target financial operating model. Revenue in the third quarter was $194.6 million, growing 36.7% year-over-year, and up from $186.1 million or 4.6% sequentially. Revenue by end markets, Networks was $150.1 million and 77.2% of total revenue, up 43.5% year-over-year. Multi-market was $23 million and 11.8% of total revenue, up 17.5% year-over-year; and Aerospace & Defense $21.4 million and 11% of total revenues, up 18.3% year-over-year. Of that total Network revenue, Optical was $55.7 million or 28.6% of total revenue, down 16.1% year-over-year. Data Center was $57.8 million or 29.7%, and up more than 300% year-over-year; and other Network revenue was $36.7 million or 18.8%, and up 52% year-over-year. To provide additional color as to the decline year-over-year in Optical, PON was $8.3 million and 4.3% of total revenues, down 70.8% year-over-year compared to $28.2 million or 20% of total revenue. Non-GAAP gross profit and gross margin in the fiscal third quarter was $113.7 million and 58.5% of revenues respectively, compared to $81.5 million and 57.3% of revenues respectively year-over-year and $108.9 million and 58.5% respectively on a sequential basis. In terms of operating expenses, total non-GAAP operating expenses were $60.8 million compared to $46.6 million year-over-year and $60.3 million sequentially. Adjusted operating expenses were up 30.5% year-over-year and up 0.8% sequentially, including AppliedMicro's expenses for the full fiscal third quarter, partially offset by lower variable compensation expense. Adjusted R&D and SG&A expenses were $35.5 million and $25.3 million respectively, in the fiscal third quarter. Non-GAAP income from operations and operating margins were $52.9 million and 27.2% of revenues, up 51.7% in dollars and 11% on…

Thanks, Bob. Now let me explain what's going on as we see it, specifically in China. Clearly, we're dealing with rapidly changing demand conditions across a number of our addressable markets. The weakness that we highlighted last quarter in China actually became more pronounced across multiple carrier-based segments, notably in PON and provincial Metro/Long-Haul deployments. We are now seeing similar effects in the September quarter in other carrier-based segments such as wireless and fiber backhaul. In PON, there's been a precipitous drop in order intake and visibility for 2.5G products, consistent with what's been reported about the transition to 10G PON. While we had anticipated the transition to 10G, the decline in 2.5G has been much quicker than our customers anticipated. This is reminiscent of the transition five years ago from 3G to 4G LTE mobile infrastructure. Orders for 3G products dried up without warning, followed later by greater spending on 4G build-outs. Carriers had concluded that the 3G network simply did not meet the demands of exploding data traffic from smartphones, so they stopped spending on 3G. We understand the Chinese carriers have similarly determined that the current 2.5G PON infrastructure cannot support mandated data rates for the client. Consistent with that, 2.5G orders have dried up and we've seen a distinct shift in focus among our first-tier customers towards ramping 10G platforms in 2018. Our competitive strength in PON lies in providing the cost structure, capacity and supply chain flexibility for high-volume client side Optical Network Units or ONUs. The 10G PON opportunity today lies primarily in the central office with Optical Line Terminals. OLTs are characterized by modest volumes and represent a relatively small short-term opportunity for MACOM. We believe our PON business should recover to previous levels once client side ONUs ramp to volume. At which…

Thank you And our first question comes from Blayne Curtis of Barclays. Your line is open.

Hi, guys. Thanks for taking my question. John, maybe just walk me through the June quarter. Your Networks didn't miss, but within that Optical is down. Maybe you could just walk me through Data Center and the big step up in other, what went on there and then how you're looking at those two sub-segments into September?

Yeah. So, you're talking about Q3 results, right?

I'm talking about – you walked me through June where – that you didn't miss Networks overall because I think Data Center and really other was up a lot. Can you walk me through what that was, and then how you're thinking about them into September?

Yeah, I would say the strength in Data Center continues unabated, everything is clicking on all cylinders. And I think we reported independently so you can see that. On the other, I'm trying to think what was the major driver, Bob?

Yes, when you get into the details, a lot of the cross points which is – and some of the wireless stuff had a good quarter.

That's right.

Data Center, it's hard to track cross points, but because of that portfolio was so diverse in its end markets, it was pretty robust in the quarter. And again, we had some weakness in backhaul products as well. So, it goes to the diversification of the product mix that did lend itself to making the quarter this.

Actually the big strong growth...

What was...

Sorry, Blayne, let me just make one more point, and then take you to next question. Yeah, I mean the big strong growth sequentially was we had double-digit growth quarter-on-quarter in Metro/Long-Haul outside of China, that remains continuing – and the projection in Q4 is similar. Sorry. So, you had another question?

I was just going to clarify I know, (29:41) last-time buys, I was just kind of curious maybe you can guide on what that was and does that have any impact in December (29:52)?

No, no, no. If you're referring to the PowerPC stuff that was about flat quarter-on-quarter as anticipated.

There's no last-time buys in the Network business today.

Yeah.

(30:05).

Sorry, Blayne, you're breaking up there on the question.

I'm sorry. I'm just traveling, but if you can hear me now...

Yes.

I was just curious, PON is down to a pretty de minimis level. You said you're being cautious to your Long-Haul/Metro, does that mean flat or are you actually modeling it down again in September? And then if you can just also just talk about – you had a great trajectory in lasers, is that still on plan to what you had previously stated about doubling?

Yeah. So Metro/Long-Haul is flattish from a Q3 to Q4 standpoint. That said, I won't say slightly down, double-digit, low-double digit down quarter-on-quarter in China, continued growth double-digit sequential in Metro/Long-Haul outside of China. You're right, we get down to de minimis levels on PON as we go into that transition. And did I miss – there was another aspect to the question.

Data Center is still strong. Our other Networks stuff..

Oh, yeah, lasers.

...other Network products, that's going to be down slightly, that's some of the stuff that's hard to predict in the portfolio, but still at this point...

Let me give you a great example of the other stuff. The OTN framer is coming in from the connectivity stuff that sell into telecom, also shows slight weakness in the backhaul stuff, we said wireless interest, the mobile infrastructure stuff, fiber and wireless backhaul, looks to be softening for the next quarter. You made a comment about the lasers. So, our plan has been as articulated in May to double output quarter-on-quarter. We actually tripled last quarter and we're really teed up for a breakout from a supply standpoint. We're completing the mobile qualification in August. So, from a supply standpoint, we'll be unlimited beginning in the December quarter. Now that said, we need to complete the vendor qualification, the customer qualifications, get the orders that actually produce the material. So, the laser opportunity looks to be poised for a breakout.

I guess I'm still confused. What is driving the sequential decline into September, maybe I'll try it at a high-level?

Sure. So, both PON drops down to de minimis levels and further decline in the Metro/Long-Haul . If you look at the decline, it's about half that and half PON. And then relative to consensus, the other $10 million would be a combination of backhaul and OTN framers. And all of that – everything I just mentioned is 100% China.

Got you. Helpful. Thank you.

You're welcome.

Thank you. And our next question comes from Harlan Sur of JPMorgan. Your line is now open.

Hi. Good afternoon. Thanks for taking my question. Can you just help us understand directionally, obviously networking will drive almost or all of the decline in the September quarter. How do you see A&D and multi-market trending quarter-on-quarter? And I think that you guys have put some of the A&D programs on hold given the full fleet of Data Center products. Are you guys starting to reaccelerate some of the productization of some of these A&D programs?

Yes. So, for the fourth quarter you'll see between our multi-market and A&D businesses good sequential growth. And part of that contribution is exactly what you mentioned. We deferred some of the fulfillment on demand orders that we had and we'll be shipping at least part of that, if not all of it.

Great. Thanks for the insights there. And then, maybe if you could just help us quantify, just looking back to the June quarter at your Optical business, of the $56 million in revenues for that segment, it looks like $8 million was PON. So, of that remaining $48 million, how much of that was focused on China Metro and Long-Haul, just kind of rough numbers would be great?

So, I would say – so, last quarter you're talking about Q3?

Yes.

So, we try not to report on the product line basis, but it was down substantially, it was down 50% sequentially in China on the Metro/Long-Haul business. So, that's where you see – I mean, we did not anticipate in our last guidance. That decelerated or it further deteriorated after our guidance. We made up the difference frankly with outperforming on Data Centers for the most part, and as well as outside of China. I mean we're up close to 10% sequentially outside of China in Metro/Long-Haul . So, you can see the reason why I say this is a very acute China phenomenon that we're dealing with right now.

Yes. In fact we've added more customers to the overall Long-Haul/Metro roster. I think we talked over 30 the last time. When you add the client side of the business that's emerging now on the Metro side where – and including guys that are taking samples and at least starts the design process, it's well over 50 customers today. So, the potential and the way it's aligning to the rest of the world and that includes great strength out of Japan, Europe and North America with multiple equipment suppliers and transceiver manufacturers, it's offset though by the world, what's going on in China.

Hey, Bob, just one last question for you. Sorry, I haven't worked through the numbers yet. But can you just give us a rough sense on where you're going to take the OpEx levels this quarter?

OpEx at mid-range, the EPS numbers around – it's up slightly to about $63 million.

Okay. Thank you.

Thank you. And our next question comes from C. J. Muse of Evercore. Your line is now open.

Yeah, good afternoon. Thank you for taking my question. I guess first question, high level question here. If we look back to your last earnings cycle, you talked about PON turning weak, I think in the last four weeks before reporting. And I assume that it's only gotten weaker through the quarter. And I guess the volatility there is not something that would be terribly unusual. But what I'm trying to understand is why you were so bullish on your Investor Days during that period? Can you help me understand kind of your thought process there and the timing of when PON really took a turn for the worse?

Yeah, I don't think we're bullish on PON in the investor forums, I would say, but to answer to your question...

No, it's more on your outlook and perhaps maybe it was more a long-term focus, but I think we all interpreted a more robust Data Center ramp amidst that.

Well, we're exceeding our internal plans and expectations in the Data Center stuff. So, there's nothing in our results at all that has to do with Data Center performance to expectation. This is 100% concentrated, geographically in China and its multiple carrier segments. And again, to your specific question about PON, is it spot on the point? Going into the quarter last quarter and through our guidance, what I had – my bellwether, I just came back from China, normal customer connections and so on, making sure that our share is intact, the markets are happening. Frankly, the order intake dried up and trying to understand what the heck was happening. Going into the quarter, we were guided by our major customers saying, look, expect 15%, 20% unit decline year-on-year for the 2.5-gig PON. Well, what happened this quarter after we guided was – no, no, it dried up completely. One of our major customers literally stops production, exited 2.5G PON production. And then we started getting reports independently of the carriers concluding that they need to switch to 10-gig PON deployments rather than 2.5 gig. So, that was a surprise, that was totally new information that we did not have insight into going into the last quarter guidance.

That's helpful. And I guess as a follow-up question on the AMCC side, two questions there. I guess first part, what should we be modeling there for the PowerPC end of life revenues for September? And then as you think about getting a minority stake on the equity side, how does that change your thinking around the ROI of that acquisition? Thanks.

Okay. Two questions. The first one is fairly simple. The PowerPC business is not a growth business. We said that from post last quarter in terms of getting it behind us in terms of its dilution to the margin and I would not expect a large part of revenue to be part of that in the fourth quarter, and it's included in our guidance that way. ROI is a tricky thing, I think we have – that's one element. And again, post acquisition when we mentioned that we would be divesting the Compute business, that we assume some minimum valuation in the fairness opinion presented to the Board of Directors. We are conservative in the valuation of the carrying amount of those assets. Again, I reiterate this is not going to be a business run by the former management team. It is a new, professional, extremely experienced processor team, with an all-star cast. And I think, it's quite frankly, an all or nothing, either they're going to be hugely successful, or we'll have lower returns.

Yeah. I can provide a little more color. During the due diligence, which you can imagine was very intense for this buyer, the customer feedback in major industry players, including cloud service guys was spectacular. Very, very supportive for the transaction. And I think the real bellwether that I have is what Bob was hitting on which is the pedigree of the new ownership and management team is profoundly superior on a go-forward basis. So, the opportunity – and it is all or nothing, either you succeed, and they are very well poised for success. And when you see the pedigree, you'll understand what we're referring to. Or it flames out and it is what it is. But what we used in our fairness opinion was relatively de minimis. And frankly, is dwarfed by the opportunities that we now see on the PAM4 and the MACsec stuff. So, we've always been fairly conservative in terms of a valuation on the Compute business.

Excellent. Very helpful. Thank you.

Yes.

Thank you. And our next question comes from Quinn Bolton of Needham & Company. Your line is now open. Quinn Bolton - Needham & Co. LLC: Hey, guys. Just wanted to come back to the other segment within Networks. Can you just describe what products are in that? I thought it's on the wireless – or sorry, Optical back haul for cellular networks was included in your Optical business. It sounds like that's perhaps in the other bucket. So what's in other?

Well, there is a portfolio of about 12 different product categories. And in any given quarter, these things move back and forth. We talked about the portfolio of cross point switches that has been around for a long time that has – it seems to continue to have new applications. It's a functionality in a chip that reduces latency issues, enhances latency. And it finds new markets and the team has done a good job to continue to expand that opportunity. To focus on any single component is really hard and really is not giving the right context of the business.

Yeah. I can give you more flavor on some of the other diversity stuff. We've got the wireless backhaul point-to-point portfolio that we've had at MACOM for 5 years-plus. Fiber backhaul is reported in that. Laser is going into mobile infrastructure. OTN framers and mappers, that is the business coming in from AppliedMicro. We have an old legacy Voice-over-IP piece that came in from Mindspeed three years ago. It's all kinds of bits and pieces. And like Bob said on a quarter-by-quarter basis, things pop around up and down and sideways. Quinn Bolton - Needham & Co. LLC: Got it. So within that other bucket, the OTN framers, mappers, the lasers for cellular back haul declined sequentially into September, given the China – well, the China part of that business declines?

Correct.

Yeah. So, we're seeing exactly what other people are reporting, which is mobile infrastructure is looking weak for at least the September quarter. That's the only visibility we have, but it was previously strong. But that cycled back and forth over the past few years. But I can only tell you September is looking soft for that business. Quinn Bolton - Needham & Co. LLC: So, then just shifting over to the Optical business, which was in the mid $50 millions, that's just the PON business and the Long-Haul/Metro revenue. Was there anything else in that Optical bucket?

No, it's Long-Haul/Metro, it is the PON business, and the rest goes into the Data Center bucket today. Quinn Bolton - Needham & Co. LLC: Okay.

Yeah. We pulled some of Data Center related stuff out, they used to have Data Center.

There is a small piece of the framer business OTNs that go also into Optical applications, as well as other enterprise applications.

Yeah. Quinn Bolton - Needham & Co. LLC: Okay. And I assume given your comments on the Data Center business that you would expect sequential growth in Data Center within the Optical bucket into the September quarter?

Yes. Quinn Bolton - Needham & Co. LLC: Great. And just last question for me. You guys have talked conceptually about selling directly to some of the hyperscale customers where you provide your reference designs and they can build those. Can you say whether or not you've entered production in any of those types of engagements with that model?

Yeah. So, let me just clarify because there's a subtlety that is a sensitive point with our customers, that I think people have misinterpreted our comments. So, our model is, we engage with the cloud service guys, not just because of our desire to, but the cloud service and major data center guys are very professional in their supply chain management. It's like the personal computer industry, they engage directly with the semiconductor suppliers and the electronic component suppliers to make sure the supply chain is setup with the right capacity, supply chain flexibility, the right products, the right technology. And so, that's their model, it's not us trying to do something different. And we're recognized by all the major cloud guys, I mean, we had one of the mega guys at OFC come into our booth and say we open up all these transceivers and they're chock full of MACOM components, 7 out of 10 by our estimate includes our content. So, they're engaging with us. And the answer is with all of these guys, we have a lot of transceiver customers servicing each one of them, and there's multiple per one, right. And now there's been some coverage lately of some successes and so on. Let me tell you my emotional reaction to that: that's one of many. It's not the only one. It's not a singular event. It's one of many with different product configurations, different standards, and different transceiver suppliers. Quinn Bolton - Needham & Co. LLC: Got it. Thanks for the additional color.

Yes.

Thank you. And our next question comes from Mark Delaney of Goldman Sachs. Your line is now open. Mark Delaney - Goldman Sachs & Co.: Yes, good afternoon. Thanks very much for taking the questions. First question is a follow-up on the China 100G push-outs relative to what the company had been looking for as of the last call of potential increase in the September quarter. John, I know you said you're just over there and I think you made some comments specifically about what's happening in PON relative to your prior expectations. Could you just elaborate a bit more on the 100G opportunity? And is any of the weakness either share loss or incremental pricing pressure, or is it all just lower end demand?

No, I mean one of the reasons why I go over to those customers is, I'm very sensitive to share issues, gaining share, losing share. And yeah – and when the orders dry up, you start worrying about the worst, right. I can tell you zero indication of share loss. We're in mid-cycle with a lot of these programs, and you just don't switch suppliers, I mean, it's not like these are multisource things and so on, it's 100% end market-related issues. Let me give the kind of flow, and if you look at major players in the industry, and I'll give you – Acacia is a great bellwether selling into China as well. There are a lot of people who've been successful not just us. In the December quarter, in March quarters very, very strong. And what happened was in the – as we're exiting the March quarter with our April guidance, we started to see softening and we tried to emphasize that – some would argue, overemphasize that in our last earnings call. And then after the earnings call it continued, the visibility did not come back. At OFC, which was in March, we had major customers and carriers talking about provincial deployments that would begin in the fall, which would indicate – people asked about the September quarter, I said look – September is going to depend upon, is that sooner in the fall or later in the fall. And now, people are saying, well end of the calendar year. So, we literally have customers who mid-quarter said, stop shipping products and they have not, and will not place orders for delivery in September until they burn out the inventories and those provincial deployments continue. I mean it's...

This is telecom. See this is a major qualification process, so you're not swapping out boards as...

Boards, components or otherwise, they're mid programs.

Yeah.

They're not new programs with changes in suppliers and so on. Very sensitive to the point, but I can tell you this is 100% about specifically China and specifically end-market health, cyclical issues. Mark Delaney - Goldman Sachs & Co.: Got it. That's helpful detail. Second question, switching gears a little bit on the 25G lasers. I think you said tripled output, so is my math right, you're at 600,000 units as of last quarter. And then as you bring on Lowell hopefully later this summer, does that get you all that way to that 5 million units to 8 million units of capacity that you had in PON or is there still additional factories that would need to convert? And maybe you could also just talk a little bit about how the yields are on the 25G lasers versus 2.5G?

Well, yeah. I mean, you're talking about a fully mature – I mean, I think we've sold 200 million lasers in 2.5G. And you're talking about numbers that are orders of magnitude less, so totally different stage of yield curves. But it is several integer multiples higher yields quarter-on-quarter, which is consistent with tripling capacity out of our Ithaca factory. I'll put Lowell this way. Once we have Lowell qualified and we're on a midpoint through the high temperature operating life qualifications and everything's looking great and all indications are things will complete. I mean it's a transfer of something from one factory to copy exactly to the next factory. We'll have the equipment capacity and the ability to start enough (50:40) material to supply 100% of the Data Center market for the foreseeable several years. Now, I should say, that doesn't mean we're qualified and all the customers necessary to place the orders and fulfill that demand, but there will no longer be any kind of capacity bottleneck in the industry servicing 100 gig transceivers, 100 gig or even 400-gig transceivers.

And Lowell is a 4-inch fab versus a 3-inch fab.

4-inch versus 3-inch, frankly, from a yield standpoint, a lot more reliable and robust. It's a world class compound semi-fab that's perfect. And as you can see, we're shipping 8 million a month at peak into PON. And there's no reason at maturity, we can't do the same thing with 25 gig lasers.

Or more, really.

Or more. I mean 8 million was not the limit by any means. But if we can sell 8 million per month of 25 gig lasers, I'd be pretty happy to put it that way. Mark Delaney - Goldman Sachs & Co.: Right. And if could just sneak one more in on the GaN for base stations. I think last quarter you probably talked about having a couple of different qualifications, one at 900 megahertz and one at 1.8 gigahertz and that those were supposed to be done in the June timeframe. How did those fare? And are those programs still on track for production ramps in the – I think it was December to February timeframe was what had been communicated previously?

Yeah, the initial design-ins we have, we actually have more frequency bands now than we had before. I think I talked about 900 megahertz and 1.8 gigahertz, we now have wins with 3.5 and 2.3. And all of those initial quals completed, we have additional quals completing in September. We have a major customer audit, which is the conclusion of all of this qualifications stuff, August 10. Full expectation, that's going to go well in which case, we're going to be off to the races with geometric proliferation of program wins on a go-forward basis. But let me say, what I've always said, which is we're not through the gate until we're through the gate. August 10 is not – this is August 1, not August 10. So, everything is looking very, very exciting. My confidence genuinely over the past year, quarter-to-quarter-to-quarter has continued to grow, the inflection point, could be within the next 30 days. Mark Delaney - Goldman Sachs & Co.: Thank you.

You're welcome.

Thank you. And our next question comes from Tore Svanberg of Stifel. Your line is now open. Tore Svanberg - Stifel, Nicolaus & Co., Inc.: Yes. Thanks. I know you don't want to report on the product lines, but the Long-Haul/Metro, which looks like is around $47 million. How big of that is China? Is it half? Is it a quarter? Again, I'm not looking for a specific percentage, but just rather rough magnitude.

So, China business overall, at its peak was almost 40% in our fiscal Q1 is down to 30%, but that's not just Long-Haul/Metro.

Actually those numbers tie in with the stuff I have in front of me here, Bob.

Yeah. It's just that we do sell some other products to China and China includes Hong Kong, because it's a port of entry and gets around some VAT taxes for some of the customers for us at least. And so, it's softening as this trend has happened.

Yeah. Back in the second quarter for Metro/Long-Haul, it was pretty close to 50/50 inside and outside China. Q3, we had fairly precipitous decline in China, continued sequential growth close to double-digit in outside of China. So, the China decline was precipitous. From that low number, we still see – I mean, literally orders have dried up. Customers do not want to take products in the September quarter, so there's another small sequential decline – much smaller than the previous one, but off that low number in China. And we continue to grow double-digit sequentially outside of China. So, let me emphasize something just to give you the image. From a design win footprint, market position overall, our position only grows. In terms of end market cyclical weakness, we have a short-term issue in China. Once the provincial deployments resume, we're back off to the races, right. So, this is genuinely a cyclical issue dealing with end market demand, the overall market position we have is only strengthening on a global basis.

And as more of the contract manufacturers come into play in the Data Center market, that will also increase the China penetration of end market deliveries.

Yeah. Tore Svanberg - Stifel, Nicolaus & Co., Inc.: Understood. And then, the PON was about $8 million last quarter. How should we think about that revenue going forward? So, will it pretty much go away in the September quarter? And maybe perhaps another way of asking the question is, when will be the crossover between 2.5G and 10G, will you start to see that crossover pretty soon or?

So, we're being very cautious on that exact point. This is a technology transition, it's just not a cyclical thing that 2.5G is – there was a clear inflection point. The answer that, our business will come back. That inflection point produces an overhang with an inventory burn off. It's the bullwhip effect of semiconductor guys. So yeah, 2.5G will come back at some lower level eventually once they burn off the inventories. That's about happening in September. I wouldn't anticipate that happening in December. On the 10-gig PON, there's really two waves to look to. One is the OLTs, the Optical Line Terminals which is the central office side of things. The issue there is, it's moderate volumes and our position of strength really comes in where you have the scale volume on the client side, the Optical Network Units and that is not an instant transition. So, PON's going to remain soft on the intermediate term. And again, I try to use the analogy of 3G to 4G transition in mobile infrastructure back in 2012, things fell off like a rock in March 2012 and later – quarters year later came back roaring like a lion where people couldn't supply enough product. That's what I anticipate with 10G, but I'll tell you we are not close enough with the carriers to give you a date when that's going to happen. And frankly, I wouldn't believe it until I saw it in orders anyway.

Think about it, we already shipped 200 million 2.5 gig lasers, if there's a 100% replacement market, we still have plenty of capacity for 10-gig EFT lasers.

Yeah. Tore Svanberg - Stifel, Nicolaus & Co., Inc.: Sounds good. Just last question on single-lambda PAM4s, you said everything's on track there. So, is it too early to talk about sort of what revenue contribution can be there next year? Do you have any numbers you want to share with us?

No. And I'll tell you one thing is become clear especially after our Data Center investor forums, we got to be really careful about what we talk about our lead customers level of business. There's a high degree of sensitivity with our customers talking about their business to investors, when you get more diversified businesses with multiple customers, it helps. When you have one big lead customer driving your business, we got to be really cautious. So, long-winded way of saying, no. Tore Svanberg - Stifel, Nicolaus & Co., Inc.: Okay. Sounds good. Thank you.

But I can tell you their internal program delivering the full transceiver using that single-lambda PAM5 is very smoothly flowing through. They'll be in a position this fall to be sampling to their customers. It's the risks that were there before this quarter was, well, they would have to complete their products, so there's always technical risk in their own development and that is going very well. And so, everything looks to be right on track for their own internal schedules. And it is a strategic program of real significant interest with that customer. So, they're very much motivated to drive that out into the marketplace. They think it's quite disruptive in fact. Tore Svanberg - Stifel, Nicolaus & Co., Inc.: Sounds good. Thank you.

You're welcome.

Thank you. And our next question comes from Harsh Kumar of Stephens. Your line is now open.

Hey, guys. I just wanted to follow up on the previous question. I think Tore mentioned $47 million for Long-Haul/Metro. First of all, do you agree with that number? And then just relatively speaking for – you gave like a 50% down number, was that number for PON – or I'm sorry, for Long-Haul/Metro, was that for June or for September guide for us to think about? Maybe just provide some color on that.

Yeah. The $47 million number is our second fiscal quarter, so the March quarter. A little more than half of that was China, and China drops by half, so you can see a 25% sequential drop in our total. At the same time, the non-China business grew sequentially close to 10%, so that offset that somewhat. But in total, there was a sequential decline in the June quarter in Metro/Long-Haul, more than 100% attributable to China.

Got it. And then, John, you mentioned that fiscal 2018, you expect Long-Haul/Metro to pick up, is there something that you're seeing or is this just based on previous experience that you've seen with all the cycles? Just some color on that as well.

I'm sorry, which period did I say it was going to...?

I think you said next year you expect Long-Haul/Metro to pick up and come back...

Oh, geez, yeah. I mean, look, let me caution one thing. Having heard what people said at OFC and that not materializing, I'm a little bit snake bitten. I don't want to be the prognosticator of recovery. But I'll tell you, the reality is and you'll see our customers reporting over the next week or so, and I'll caution, our customers will see recovery sooner than us, we get the bullwhip effect on inventories. They're going to be talking about provincial deployments later this year. So, we don't have to wait for next year for the China stuff to come back, it's going to be coming back naturally as those deployments proceed. No one has said those have disappeared. So, I say this is a cyclical issue and we get the bullwhip effect of the inventory effect. And meanwhile, outside of China, look, we're posting multiple quarters of, on average, 10% sequential growth. So, we don't have to wait for next year for Metro/Long-Haul to recover. It's going to be soon. How soon it is, we guide one quarter at a time.

Understood. Thanks, guys.

You're welcome.

Thank you. And our next question comes from Vivek Arya of Bank of America Merrill Lynch. Your line is now open.

Thanks for taking my question. I guess John, we are all trying to guess how prolonged this downturn is. I think of course there's an understanding it's cyclical, but when the recovery would be is harder to predict. But when I look at the December quarter, seasonally, it has been flat to down for you guys over the last number of years. And I'm wondering what is the right way to think about it this time, like, should we really be expecting a recovery so late in the year? Or just what are the puts and takes for December even if it's on a conceptual basis given potential for recovery versus GaN on base station, et cetera?

Yeah. So, let me put it this way. Yeah. So, we have definitely seen in recent years seasonal softening in our first fiscal quarter, the December quarter, no doubt. To be honest, this cyclical effect dwarfs that, right. This is a precipitous decline in some businesses that are in that same region. If we see the deployments began in December quarter like people talk about, that effect in my opinion could very well dwarf the other seasonality. How much, you know the puts and takes and relative balances remains to be seen. I would say PON, I would not count on recovery in the December quarter. That's a technology transition it's not just an inventory effect with a push out in demand. And frankly, it's not that far off of what we anticipated anyway, to be honest. But at the same time, our Data Center business is marching along well-ahead of our expectations on all fronts, on all form factors. The lasers, the analog stuff continues to post very strong sequential growth quarter-to-quarter-to-quarter. We had the L-PICs now rolling out. We're going to have first major customer with very high volume capability in the fall, sampling transceivers based upon our CWDM4 L-PIC. We're just – the log is (1:04:17) next year, you actually see the material PAM4, PAM5 stuff, but it's all the matter of balance of puts and takes. The thing we're dealing with right now is just multiple segments, bad luck, everything cycling down in China simultaneously.

Yeah, MACsec is also well-positioned for...

Yeah. So, MACsec and PAM-4 are ahead of our expectations both in terms of revenue recognition as well as design win and customer adoption. So, strategically it's all very good, but all the telecom-related stuff in China, including the OTN framers, mappers, the wireless and fiber backhaul stuff, all shaping up for a soft September quarter. And it's cyclical, it is not share related, and all the reports you see start talking about recovery in China, getting back to more normal conditions as early as December quarter, I think it's just way too early for us because there's that whiplash effect with inventory, inventory burn down that until we get visibility of orders coming in, we can't call it.

Got it. And as my follow-up on gross margins, when I look at June results, I understand you mentioned some trends started to weaken. But sales were roughly in-line with the broad guidance you had provided. But gross margins were 100 basis points weaker, but then importantly when I look at your September guidance, you are expecting gross margins to go up 100 basis points even though sales are expected to come down 12%, 13%. And I'm just trying to understand why the miss in June and why would they grow in September? Thank you.

So, our gross margins are an issue of blend of the business. Our Metro/Long-Haul business and PON – believe it or not in PON among the highest gross margin businesses we have in the company. That's where the pain is the most acute. The answer to your question about the sequential growth expansion in gross margin in the September quarter has frankly a lot to do with Data Center. Data Center is yielding the same or better gross margins than those, so it's just a mix on a quarter-to-quarter basis.

And we already said that the PowerPC business is not a growth business in the fourth quarter and that's been dragging down margins.

Yes.

Got it. So, just lastly, if you were in our seat, you would be modeling December up sequentially?

We are not making comment on calendar Q4, our fiscal Q1. We have no evidence to say that seasonality will not be any different this year than we've seen in the past at this point in time. We guide one quarter at a time.

Got it. Thank you.

You're welcome.

Thank you. And our final question comes from the line of Richard Shannon of Craig-Hallum. Your line is now open.

Well, thanks, guys, for taking my question. I think I'll just ask one question, I think as the China topic has been largely dealt into here, but let me ask one quick one on PAM. John, you mentioned you have 21 engagements including, I think, the wording, I got was five programs in some level of detail there. Wondering if you could help us understand the breadth of the customer list there, would you describe them as Tier 1s and how fast do you think those programs, which I assume you're describing as past your lead customer here are expected to ramp into revenues?

Yeah. Here's the way to think about PAM4, no one refutes the fact that the IEEE standard single-lambda based standard is unequivocally the approach for 400-gig, right. And a lot – every single one of these customers we're talking about is locked on to 400-gig as we roll it out over the coming months and quarters. A subset of those people are active in 100-gig programs for multiple reasons, one of which is to be as a pipe cleaner, so if they're ready to deploy the 400-gig as a logical follow-on, because 400-gig you can think of is a quad version of 100-gig in those IEEE standards. In terms of the quality of customers, it's a, who's who list. Frankly, we don't waste our time supporting – this is heavy hand-holding, high-maintenance design wins. And we don't – I shouldn't say waste our time, we focus our energy on the guys who can move the needle, to put it that way. And literally and it's almost there's no one that isn't serious about 400-gig and 400-gig is unequivocal, and we're in unequivocally in the point position. So it's a very, very nice position to be in and that's the reason why I keep harping on the success with that like a lot of things we're doing is purely an issue of execution, getting the product out, getting it ramped into volume and getting the customer programs likewise qualified and shipping.

Okay. Fair enough. I appreciate it the detail. That's all the questions from me guys. Thank you very much.

Very good. So, before closing on today's call, I want to mention that Bob and I will be attending a number of investor events over the coming months, including the Pacific Crest KeyBanc Tech Forum on August 7 in Vail; Oppenheimer's Technology, Internet & Communications Conference in August 8 in Boston, Jefferies Semi-Hardware and Communications Summit on August 29 in Chicago; Drexel Hamilton's TMT Conference on September 6 in New York, and Citi's Global Tech Conference also in New York on the 7th. If you like to request a meeting at one of these upcoming events, please e-mail us at ir@macom.com or contact your sales representative directly. We look forward to providing an update and reporting on our continued progress during next quarter's call. That concludes today's remarks. Operator, you may now disconnect the call.
