With that, I will turn the call over to Semtech's Chief Financial Officer, Emeka Chukwu. Emeka?
Thank you, Sandy. Good afternoon, everyone. For Q3 fiscal 2018, GAAP net sales were $150.3 million, a 2% sequential decline an increase of 10% year-over-year. Q3 GAAP net sales included $6.2 million of expense for the Comcast warrant. Q3 GAAP gross margin decreased 74 basis points sequentially to 59.5% due to the higher sequential Comcast warrant expense, slightly offset by lower inventory adjustments. Q3 GAAP operating expense decreased approximately 2% sequentially due to lower share-based compensation. In Q3, interest and other expense was $800,000 compared to $2.2 million in Q2. The decrease reflects the benefit of foreign exchange gains realized from a stronger dollar and the lower net liabilities denominated in foreign currencies. Moving on to the non-GAAP results, which exclude the impact of share-based compensation, amortization of acquired intangibles, acquisition or disposition related and other non-recurring charges not tied to current operations.
Q3 fiscal 2018 net sales were $156.6 million, flat sequentially and an increase of 11% over the prior year. In Q3, shipments into Asia represented 75% of total net sales. North America represented 17%, and Europe represented 8%. Total net sales to distribution represented approximately 66%, and direct sales represented approximately 34%. Q3 bookings increased sequentially and resulted in a book-to-bill of approximately one. Those bookings accounted for approximately 50% of shipments during the quarter. Q3 non-GAAP gross margin was 61.3%, an increase of 10 basis points sequentially on lower inventory adjustments offset by less favorable product mix. We expect our Q4 non-GAAP gross margin to increase slightly sequentially due to more favorable mix. Q3 non-GAAP operating expense was $53.2 million, up slightly from Q2.
In Q4, we expect non-GAAP operating expense to decline between 4% and 8% sequentially as a result of lower work hours and lower variable compensation expenses. For modeling purposes, we expect fiscal 2019 non-GAAP operating expenses to be flat to modestly higher. In Q3, our non-GAAP tax rate decreased to 14.1% from 19.1% in Q2, reflecting a shift in regional income assumptions. We expect our Q4 fiscal 2018 and fiscal 2019 tax rates to be between 16% and 20%. In Q3, cash flow from operations remained solid at $27 million or 17% of revenue. Cash and investments in Q3 were $291 million, and our debt. The balance at the end of Q3 was approximately $232 million, leaving us with a net cash position of $59 million. In Q3, approximately 71% of our cash and investments were domiciled in international accounts, and 29% was based in the U.S.
We did not repurchase any of our stock during the quarter. The outstanding stock repurchase authorization stands at approximately $51.4 million. The primary use of cash continues to be to pay down our debt, make strategic investments, and opportunistically repurchase our shares. In Q3, accounts receivable increased 9% sequentially and represented 37 days of sales outstanding, below the targeted range of 40 to 45 days. Net inventory in absolute dollar terms decreased approximately 5% sequentially, and by four days to 110 days above the target range of 90 to 100 days. In Q4, we expect our inventory to be approximately flat in absolute dollars. In summary, we are pleased to deliver a strong financial performance in the first nine months of fiscal 2018. On a non-GAAP basis, our revenue grew 13% year-over-year.
Due to expanding gross margins and diligent operating expense control, we grew earnings three times faster, allowing us to achieve a record operating profit. Despite expectations for a more seasonal fourth quarter, we believe our focus on execution, growth from our differentiated growth engines, and diversification strategy should help us deliver a record financial performance in fiscal 2018. More importantly, position the company to continue to outperform the industry in fiscal 2019. I will now hand the call over to Mohan.
Thank you, Emeka. Good afternoon, everyone. I will discuss our Q3 fiscal year 2018 performance by end market and by product group, then provide our outlook for Q4 of fiscal year 2018. In Q3 of fiscal year 2018, we reported non-GAAP net revenues of $156.6 million, which was flat sequentially, and up 11% over the same period a year ago. We posted non-GAAP gross margin of 61.3% and achieved a record non-GAAP earnings per diluted share of $0.54. In Q3 of fiscal year 2018, demand from the high-end consumer market increased over the prior quarter and represented 30% of total net revenues. Approximately 23% of high-end consumer net revenues were attributable to mobile devices, and approximately 7% were attributable to other consumer systems. Demand from the industrial market also increased over the prior quarter and represented 28% of total net revenues.
Demand from the enterprise computing and communications end markets both decreased over the prior quarter and represented 31% and 11% of total net revenues, respectively. I will now discuss the performance of each of our product groups. Beginning with our signal integrity product group. In Q3 of fiscal year 2018, net revenues from our signal integrity product group declined over the prior quarter, as expected, but increased 6% over the same period a year ago and represented 41% of total net revenues. Demand from China infrastructure remained relatively soft through the quarter, as we had expected. We anticipate this weakness to continue into Q4. Weakness in the 2.5G PON market was somewhat offset by strength in the 10G PON market. Despite the current softness in the PON market, Semtech's PON business has experienced year-on-year growth through the first nine months of FY 2018.
In Q3, our base station business, driven mostly by China, declined, and we anticipate that this business will also remain soft in Q4. We do not expect this business to show significant growth until 5G deployments begin, sometime towards the beginning of calendar year 2019. Our data center business continues to remain very healthy. Customer interest in our ClearEdge CDR platform remains very strong as our cloud infrastructure customers migrate their optical connectivity links to 100 gigabit per second. We are seeing very good design win momentum in 100 gigabit per second QSFP28 optical modules used in mega data centers, where we believe we have a leadership position. In Q3, we announced the production availability of our latest ClearEdge product, which integrates our high-performance 25 gigabit per second CDR with enhanced laser driver and TIA, and targets SFP28 short-reach modules and active optical cables.
Our FiberEdge PMD platform, which is a complement to our ClearEdge CDR platform, is now sampling. FiberEdge expands our SAM with our first 100 gigabit per second linear driver and TIA, which provides a seamless interface to 100 gigabit per second PAM4 optics. We are seeing solid interest in our FiberEdge platform from customers developing 100G, 200G, and 400G PAM4 modules. During the quarter, we announced the availability of the industry's first fully integrated five PMD chipset for single lambda 100 gigabit per second PAM4 optical modules. This new 100 gigabit per second chipset combines our FiberEdge PMD platform with MultiPhy's Flex5G DSP platform to deliver a fully optimized, seamless PHY/ PMD solution for optical modules, targeted at next-generation hyperscale data centers.
Semtech's leadership position in high-speed optical connectivity will be further strengthened with the release of our PAM4 chipset and the release of next generation high performance ClearEdge based products. Despite the current demand softness in China, with a steady pace of new product introductions targeted at next generation data centers, we believe that our signal integrity product group is well positioned to continue to grow on an annual basis. For Q4 of fiscal year 2018, we expect our signal integrity product group to decline as modest growth in data center spending is expected to be offset by continued softness in China infrastructure spending. Moving on to our protection product group. In Q3 of fiscal year 2018, net revenues from our protection product group increased 10% sequentially, and 23% over the same period a year ago, and represented 32% of total net revenues.
Demand from our largest Korean smartphone customer increased over the prior quarter, driven by the ramp-up of several new smartphones. We also saw demand increase from our major North American handset customer. The increasing use of advanced lithography processors and the increasing use of advanced OLED displays in smartphones provides Semtech with a unique opportunity as our Z-Platform is ideally suited to protect these systems. In Q3, our smartphone strength in Korea and North America was offset by weakness in the China smartphone market. Our protection business is focused on further diversifying by introducing new solutions that specifically target the automotive, industrial, high speed computing, and communication segments. We believe this diversification, along with broader customer penetration within the smartphone segment, will help drive growth in our protection business over the next several years.
In Q4 of fiscal year 2018, we expect our protection business to decrease sequentially due to traditional seasonal declines associated with year-end customer inventory management and ongoing China smartphone softness. Turning to our wireless and sensing product group. In Q3 of fiscal year 2018, net revenues from our wireless and sensing product group decreased from the prior quarter's record performance, as expected, but increased 29% over the same quarter a year ago and represented 20% of total net revenues. In Q3, our LoRa-related business delivered another record performance with record revenues, record bookings, and record design wins. We believe we are on track to meet our goal of generating between $40 million and $50 million in LoRa-enabled revenues this year and between $80 million and $100 million next year.
The LoRa momentum across the globe continues to deliver exciting results as we expect to have LoRa-based network deployments completed or underway in more than 45 countries worldwide and over 70,000 gateways deployed by the end of this fiscal year. These global deployments are enabling the proliferation of many new and exciting use cases. The LoRa Alliance continues to grow with new global leaders joining the alliance. This week, we announced selective sampling of the industry's first disposable LoRaWAN tag reference design. This low cost, low power, disposable long-range tag enables a number of new LPWAN use cases to be realized, including smart health, smart media, and smart insurance applications. We expect that initial proof of concepts using this tag will be completed in the next two quarters with production release of the tag by the second half of fiscal year 2019.
Once the tag is fully available and proof of concept's completed, we anticipate the LoRaWAN SAM will increase dramatically as new use cases emerge. Our future roadmap includes both disposable and rechargeable flex and paper substrate tag reference designs, which we believe will enable billions of LoRaWAN tags to proliferate the IoT industry in the future. We will communicate progress related to our LoRaWAN tag strategy on future earnings calls. During the quarter, we also made several joint announcements with partners driving the global LoRaWAN momentum. These included Advantech, a leading supplier of industrial communication solutions, launched its Wzzard Node and SmartSwarm Gateway, making it possible to place sensors and install gateways in remote areas and harsh environments where they help detect potential failures and prevent costly shutdowns.
Netbox, an OEM and cloud service provider, announced it is converting its current Zigbee solutions to support the growing LoRaWAN ecosystem targeted at smart cities, smart buildings, and smart agriculture applications. ofo, a Chinese bike-sharing company operating in more than 180 cities with approximately 10 million bicycles, announced it would be putting LoRa connectivity on its bicycles to complement its current connectivity options. As the LoRaWAN standard proliferates across the industry, along with our alliance partners, we continue to look for ways to effectively promote and educate the industry on LoRa technology. We recently launched the LoRaWAN Academy with the help of several alliance partners. The LoRaWAN Academy was developed to educate the next generation of hardware, software, and computer science engineers on real-world IoT applications.
This platform provides a hands-on comprehensive curriculum for member universities to give future engineers the fundamental skills needed to develop LoRaWAN network infrastructure and LoRaWAN end nodes and drive new IoT applications. The LPWAN market is clearly an exciting emerging market, and we believe LoRa is ideally suited to lead this market. In Q3, our proximity sensing business decreased following the previous quarter's record performance. We expect this business to continue to be a growth driver for our wireless and sensing product group, as all mobile device manufacturers address the increasing global concerns around excessive smartphone RF emissions. Many more countries are now adopting stricter RF emissions control, driving increased interest and demand for our proximity sensing platforms. For Q4 of fiscal year 2018, we expect net revenues from our wireless and sensing product group to decline due to seasonally lower proximity sensing demand from the smartphone market.
Turning to our power and high-rel product group. In Q3 of fiscal year 2018, our power and high-rel product group increased 7% sequentially and represented 8% of total net revenues. Our power and high-reliability product group delivered another strong quarter of new product releases with 11 new products. Customer design-in activity for wireless charging products has picked up as industry adoption of wireless charging is increasing momentum. We are seeing increased design-in activity in the industrial and automotive markets and expect additional opportunities to emerge in the wearable segment. In Q4 of fiscal year 2018, we expect net revenues from our power and high-reliability product group to increase. In Q3, the total company distribution POS was approximately flat with the prior quarter's record performance. Q3 distributor days of inventory increased to 75 days, which represents the midpoint of our targeted range of 70-80 days.
Our distributor business remains balanced with 58% of the total POS coming from the high-end consumer and enterprise computing end markets, 42% of total POS coming from the industrial and communications end markets. Moving on to new products and design wins. In Q3 of fiscal year 2018, we released 25 new products, we achieved 2,055 new design wins. Q3 was also a record design win quarter in terms of design wins measured in dollars. Let me discuss our outlook for the fourth quarter of fiscal year 2018. Based on current bookings trends, we are estimating Q4 non-GAAP net revenues to be between $138 million and $142 million. To attain the midpoint of our guidance range, or approximately $140 million, we needed net turned orders of approximately 41% at the beginning of Q4.
We expect our Q4 GAAP earnings to be between $0.08 and $0.10 per diluted share, our Q4 non-GAAP earnings to be between $0.40 and $0.42 per diluted share. I will now hand the call back to the operator, Sandy, Emeka, and I will be happy to answer any questions. Operator?
Thank you. Ladies and gentlemen, if you have a question at this time, please press star followed by the number 1 key on your telephone keypad. If your question has been answered, or if you'd like to remove your line from the queue, you may press the pound key. Our first question comes from the line of Craig Ellis with B. Riley FBR.
Thanks very much for taking the question, congratulations on the good quarter, guys. The first question I had is just digging into some of the gives and takes across the fiscal fourth quarter. If I heard you correctly, Mohan, it sounds like power management will be up, the other segment's down. Guys, I'm wondering if you can just give us some color on the relative declines for some of the segments, whether it be signal integrity, protection, et cetera, as we look at the dynamics at play as we close out the year.
Craig, from the signal integrity standpoint, it's more continuation of the China weakness, mostly China infrastructure, both PON and base station. Q4 is typically a little bit stronger, I would say, for that business, but it's quite weak. We are anticipating in Q1 it will start to pick up again, but for Q4, it's weaker than normal because of the China weakness. On the protection side, I would say it's more seasonal. This is historically a down quarter for our protection business, driven by the smartphone customers in Korea bringing down their inventory. It's perhaps a little bit weaker than we would normally anticipate, again, because of China smartphones being a little bit weak. I would say those are the two main factors. Obviously, our wireless and sensing business, we have a growing proximity sensing business, which has some exposure now to smartphones.
That is seeing some weakness in Q4 also.
Following up on the LoRa business, Mohan, clearly there's been a number of announcements recently that show that the inflection towards endpoints is starting to gain traction, and you talked about some new products that could really accelerate that given form factors and power characteristics and that kind of thing. Can you talk a little bit more specifically about how you see the evolution of the LoRa revenue mix over 2018 and into 2019 as we move from what I think could fairly be characterized as a hub-centric year in the year that's about to wrap up to what may be a more balanced year next year, or if not, in 2019? How do we think about those broader parameters?
I think so. Now the infrastructure is starting to get deployed. Clearly now it's the opportunity to connect sensors to those gateways, and that's what we're seeing, and that's why I report on the number of gateways being deployed. Obviously you noticed that it's increased to 70,000. We're ahead of schedule there. Now, each one of those has the capacity for a number of sensors. We believe there's enough capacity now for 350 million sensors, which will, over the next few years, start to get implemented. That's really good progress for us. One of the reasons I pointed out the tag release, and we announced the tag, is it really opens up a new IoT segment for the industry, actually, and also for Semtech.
The disposable tag, it's really a concept of connecting this tag to these gateways or micro picocell gateways and being able to trigger a connectivity response based on an event. It's really an exciting development for us. We are obviously still early in this plan here, but I think it can really open up the revenue starting towards the second half of next year.
That's helpful. The last one until I jump back in the queue for Emeka. Emeka, seems like you've got some good near-term mix dynamics going on the gross margin line. As we think about calendar 2018, can you just identify some of the pluses and minuses as we look at the gross margin line? What's a tailwind as we go through the year, and are there any headwinds that we should be aware of?
Craig, yeah. As you know, our gross margin is really driven primarily by the mix of the revenues, right? As I look out into our fiscal 2019, I see continued growth, strong growth from a lot of product groups, and that should be a tailwind for gross margin. We do believe that our data center business, which this year is growing at about 20%-30%, continues to grow very aggressively next year as well. That should be good for our gross margins. I think on the headwind side, if you will, is the smartphone that is a growth driver for us as well, that even though we're expecting to continue to see a gross margin expansion within our protection business going into the smartphones.
Because that has an overall gross margins that is lower than the corporate average, that will be something that could put pressure on the gross margins if we see some really strong growth from our smartphone business.
Got it. Thanks, guys.
Thank you. Our next question comes from the line of Rick Schafer with Oppenheimer.
Hey, thanks, guys. I have a couple questions. I guess the first one is, would you be able to give a sense of just how big PON and base station are now on a combined basis as a % of sales and just a rough idea? Combined, are they below 10% as we look forward? Just give us a sense there.
Yeah, Rick. What we've talked about is base station has been sort of in that mid-single digit range with PON sort of the high single, low double digits. The two of those together are in sort of your mid-teens % of revenue when you roll the two together.
Okay, thanks. Just a quick update on the CDR business. When do you guys expect, or what's the latest in terms of your guys' expectation on the move to single lambda 100G? Maybe, Mohan, what has to happen to spark that move to single lambda? Do we have to hit a certain cost or price point? Is it something else that the industry's waiting for?
Well, I think the industry will move when the cost point is there, the products have to be there, and the solutions have to be there. From our standpoint, we will be sampling end of this year a single lambda solution. Our expectation is probably by mid next year, end of next year, we start to see some form of ramp with some module customers. I think it will be the following year before we see material revenue. I think it's important from our standpoint that we have solutions that are there today with our ClearEdge family, our CDR family, and our FiberEdge family coming out also. Regardless, we have an analog solution today and then a combined solution when the customers switch over.
The switch is going to be driven by the price per gigabit, that's a function of getting the optics the right price point and making sure that the solution is a cost-effective solution. I expect that some of the current technologies will also be reducing in price. It'll put a little bit of pressure on the transition. I think we're in very good shape to not only ride this current success of growth of the 100G solutions, QSFP28 type solutions, when they do move over to the PAM4 single lambda solutions, I think we'll be in good shape to transition with them.
If I could sneak just one more in. Could you give any color or discuss the trends in discrete protection attach rates as we move to 10 nanometer and below? What do you see your protection SAM doing? Maybe give a sense of maybe what kind of growth rates that could drive for your protection business.
Yeah, that's a good question, Rick. I think definitely the SAM will increase. That's our belief is the industry's going to come more to us as these advanced processes go to more advanced lithographies. As I mentioned on my script. The transitions continue to occur.
Thank you.
Thank you. Our next question comes from the line of Cody Acree Drexel Hamilton with Drexel Hamilton.
Hey, guys. Thanks for taking my question. Mohan, if we could go back to the signal integrity guidance, weaker here in Q4, but you're giving some indications of some improvement expected in the first half. I guess, what's giving you that indication and maybe your level of visibility or confidence there?
I would say, Cody, it's more a question that Q4 and Q3 are relatively soft for our China business and infrastructure business. There are indications that that one's going to be a little bit better next year. I would say that we have no real evidence of that yet, but there are indications from our customers that there's going to be some improvement. I would say on the data center side, we continue to see strength. My sense is Q1 is typically a very strong quarter for our CDR business, and that's our expectation this next year also.
Are you seeing orders in hand, or is this just anecdotal comments from your customers?
I would say on the data center side, we have a little bit better visibility. On the infrastructure side, it's still relatively soft.
As you've tried to parse out what's going on with the softness in handsets, China versus the kind of typical inventory correction at your large Korean customer, is that inventory correction in Korea larger than you would have expected? Or is it more heavily weighted, I guess, just softer guidance into what's going on in China?
I would say the inventory correction is about normal, Cody. Perhaps we've had a very strong year so far in this business, the smartphone business, both protection and our proximity sensing. some of that might be inventory runoff in Q4. I think the China smartphone issue is more indicative of China smartphone manufacturers not doing as well as they had anticipated, and that hopefully will change next year.
just lastly, I guess just any visibility into what your expectations are for the first half of 2018, just seasonally.
We're anticipating that next year is going to be another strong record year for us. Whether it plays out the way it did this year, which is a very strong first half, a record first half, actually a record first nine months, and then a weaker Q4, I don't know. That's our anticipation, though. I think we'll have a strong first half again next year.
Okay. Thanks, guys.
Thank you. Our next question comes from the line of Tristan Gerra with Robert W. Baird.
Hi, good afternoon. Back to the China infrastructure business, what sequential decline should we expect in the coming quarter? Also, how does the inventory situation look like in that business in China currently?
Hi, Tristan. I think that if we look at the business, we're looking at seeing additional declines for both the base station and PON, although offset by some of the growth in the data center market. That really will be what drives that business, those two dynamics.
Okay, any color in terms of inventories? When do you expect a stabilization in that business?
Yeah, I would say, Tristan, in that business, it's not so much about inventory as so much as it is CapEx and infrastructure spending in China. PON is not as bad, but the base station side of it seems to have certainly weakened. As I said on my script, that I don't think it's going to come back to grow significantly until the 5G deployments start to occur, which is probably going to be closer to the end of next year and early 2019.
Okay, in your LoRa business, outside of STMicro and Microchip, are you engaged or are you seeing other chip companies interested in licensing your technology?
The answer to that is yes, but we're not focused on that. Our focus is on growing the end nodes and growing the use cases. As opportunities are in front of us, we look at them on a case-by-case basis. Certainly, of course, if there are other chip companies that complement our capabilities, STMicro and Microchip are both microcontroller companies, and there are others that complement us, then we will continue to work with them.
Great. Thank you.
Thank you. Our final question for today comes from the line of Hamed Khorsand with BWS Financial. Please go ahead.
Hi. Thanks for taking my questions. First off, how much more can you see ramping as from your proximity sensors? If you're looking at the other Design wins that you have in your other product lines?
The proximity sensing is doing very well for us. It's targeted, obviously, at the smartphones where you have the RF radios, the emissions from that, and managing the radio power control. It's doing very well. Obviously, we have a strong penetration of the Korean smartphone manufacturers. We're starting to get traction at the Chinese smartphone manufacturers also. One of the things that is clearly happening is that there are regulations around the world that are expanding to ensure that there are some controls on the RF emissions and the power to prevent any issues associated with the human body. That's a good trend. So, yeah, we expect it to continue to grow next year.
Okay. Then in LoRa, this aspect, I heard you say it's now at 70,000 as far as your expectations for gateways. That's higher than the last numbers you had been indicating. Is this because there's capacity in the gateways that have been installed, or is this more a footprint of the network being expanded?
That's more a statement of more gateways being installed. We set ourselves a target that we look at, and I had said that at the end of this year, we would expect 65,000. That's what we were hearing from all of our partners. 65,000 macro gateways were going to be deployed. We're now saying 70,000 macro gateways. Each one of those gateways connects to about 5,000, has the capacity to support about 5,000 sensors. That gives you an idea. If there's 70,000 gateways out there's a capacity out there for 350 million sensors. That gives you an indication of if we were to have full utilization of those gateways, then there would be 350 million end nodes out there.
Our goal, of course, is to double, triple, quadruple the number of gateways, the number of sensors out there, and then start to really drive the use cases. That's one of the, as I mentioned a couple of times, the LoRaWAN tag that I mentioned on my script is really an important aspect to our strategy because it drives a whole set of new use cases that I believe will drive the need for many more gateways as well.
The final question is, just so we have a greater understanding of what you're talking about from a seasonal aspect, what's different this time around from a seasonal perspective that you're seeing versus what was going on in Q1 of this year, Q4 of last year? It seemed like you were in the same marketplace with the same product lines, but you weren't really seeing any seasonal differences. What's going on at the customer level [right now]?
Well, I think let's take away the China phenomenon for a second and just talk about the seasonality of the business. We typically do see our Q4 come down for our protection business. That's typically associated with smartphones, and we see inventory management by Samsung and some of the other guys. They do typically bring down their build plans in Q4. That's normal, I think, for our protection business and our sensing business. The anomaly this Q4 is really in our SIP business, in our signal integrity product business, which normally I think we would anticipate to have been stronger. There, as I mentioned, it's mostly China-driven. The China infrastructure seems to have become even softer, that's really what's driving that. I wouldn't say that's necessarily a seasonal factor.
Okay, good. Thank you.
Okay.
Thank you. That concludes our question and answer session for today. I'd like to turn the floor back over to Semtech for any closing comments.
Okay. In closing, while we are expecting a more seasonal pattern for our Q4 results, I am pleased with our solid performance for the first three quarters of fiscal year 2018, which should enable the company to deliver record financial results this fiscal year and provide a strong platform for further growth next year. We expect our key growth engines should continue to benefit from a number of secular demand drivers. With that, we appreciate your continued support of Semtech and look forward to updating you all next quarter. Thank you.
Thank you. Ladies and gentlemen, thank you for your participation in today's conference. This does conclude the program, and you may now disconnect. Everyone, have a great day.
