Good afternoon, and thank you for joining us today on Synaptic's fourth quarter fiscal 2021 conference call. With me on today's call are Michael Hurlston, our president and CEO, and Dean Butler, our CFO. This call is also being broadcast live over the web and can be accessed from the investor relations section of the company's website at synaptics.com. In addition to a supplemental slide presentation, we have also posted a copy of these prepared remarks on our investor relations website. The supplementary slides have also been furnished as an exhibit to our current report on Form 8-K filed with the SEC earlier today and add additional color on our financial results. In addition to the company's GAAP results, management will also provide supplementary results on a non-GAAP basis, which excludes share-based compensation, acquisition-related costs, and certain other non-cash or recurring or non-recurring items. Please refer to the press release issued after market closed today for a detailed reconciliation of GAAP and non-GAAP results. Additionally, we would like to remind you that during the course of this conference call, Synaptics will make forward-looking statements. Forward-looking statements give our current expectations and projections relating to our financial condition, results of operations, plans, objectives, future performance in business, including our expectations regarding the potential impacts on our business of the COVID-19 pandemic and related supply chain disruption and component shortages currently affecting the global semiconductor industry. Although Synaptics believes our estimates and assumptions to be reasonable, they are subject to a number of risks and uncertainties beyond our control and may prove to be inaccurate. Synaptics cautions that actual results may differ materially from any future performance suggested in the company's forward-looking statements. We refer you to the company's current and periodic reports filed with the SEC, including our most recent annual report on Form 10-K and our most recent quarterly report for important risk factors that could cause actual results to differ materially from those contained in any forward-looking statement. Synaptics expressly disclaims any obligation to update this forward-looking information. I will now turn the call over to Michael.
Michael Hurlston
Great job, Steve, and welcome everyone to today's call. We had an exceptionally strong end to our fiscal year 2021, and I'm pleased with the continued execution of our strategy of IoT diversification and profitable growth. Revenue for the June quarter was higher than the midpoint of our prior guidance and was significantly above normal seasonal trends, driven by our intentional shift toward a diversified portfolio and customer base. As IoT growth continued, profitability remained strong, resulting in another record quarter for both GAAP and non-GAAP gross margins. Our non-GAAP net income and EPS exceeded the high end of our guidance range, a result of our structural portfolio improvements coupled with discipline spending. Our non-GAAP operating margin was greater than 30% in the quarter as we continue to improve upon our efficient financial model. One of the key pillars of our successful transformation strategy has been the pivot of our focus from the mobile market to IoT. we now have a broad range of market-leading products for IoT encompassing automotive, audio, video, docking, and wireless applications. As a result, our IoT business has grown significantly with revenue in this category now contributing more than 50% of our quarterly sales. Meanwhile, our mobile products, which once comprised in excess of 80% of our total revenue, now represent approximately 25% of our quarterly sales. While the development of touch and display driver technologies will continue to be important, our goal will be to operate mobile at 20 to 25% of our revenue mix. A second but equally important pillar of our strategy is to build and grow our portfolio with high-value, market-leading products. We continue to believe that gross margin provides the best correlation to product value. Over the past 24 months, our non-GAAP gross margins have increased by more than 1,800 basis points, an incredible achievement, one that we believe less than a handful of companies in any industry can claim to match. This accomplishment is all the more impressive that it was attained in a mere eight quarters. Our fundamentals have never been stronger, and we see clear avenues for organic growth in all three areas of our portfolio. Finally, I'd like to introduce our updated mission statement, one that unifies all the elements of our portfolio. To engineer exceptional experiences for consumers, whether they are at home, in the office, in their car, or on the go. I am pleased to report that our strategy of building experience-centric products has resulted in increased traction in cross-selling our full portfolio, with more than half of our top 20 customers buying three or more distinct technology categories from Synaptics. As an example, in order to count, a customer would have to buy audio, wireless, and display drivers from us. On the other hand, a customer buying three generations of touch ICs would not count. Now, let me update you on our business. In IoT, we continue to build momentum in our world-class wireless connectivity products with numerous new wins spanning a broad range of applications. Our recent efforts in establishing and expanding our sales channel utilizing our strategic module partner AMPAC has enabled us to rapidly access and support a growing customer base. Through this partnership and other ecosystem engagements, we've doubled our revenue over the past 12 months with wins in home automation, surveillance, video doorbells, wearables, and fitness-related applications to name a few. Our best-in-class Wi-Fi 6 and Bluetooth combo chipsets are seeing great traction with customers designing new solutions or upgrading their existing products. We have also secured several new design wins with our GPS solutions, particularly in wearables. Given our pace of success, we see a path to doubling once more in the next 18 months. Our audio franchise continues to be recognized for its industry-leading performance, particularly in adaptive noise cancellation and 3D sound simulation. Our feature set gives us advantages in high-fidelity headsets where we've seen significant traction over the last year with many consumers, call centers, and enterprises upgrading their audio solutions. As people return to work in a hybrid environment, we expect continued strength in our devices for high-end headsets, along with new opportunities for our certified audio solutions for collaboration environments, such as Microsoft Teams and Zoom. In automotive, our display and touch solutions are now either in production or qualified on 45 car models at more than 20 OEMs that include US, European, Korean and Japanese auto manufacturers, as well as many of the EV startups. As the center console evolves into a richer and more interactive media center, Synaptics is well positioned to capture a significant portion of this market with an anticipated increase in our silicon and dollar content per vehicle. Automotive is now one of our fastest growing product areas, And I'm pleased to update you that we are now ahead of plan by almost a full year and expect to achieve our a hundred million annual revenue goal by the end of fiscal 2022. In video interface, demand for protocol converters is strengthening with Synaptics being first to market with full support of the HDMI 2.1 standard. Our new dual chip solution combining both display link and DisplayPort technologies represents the only solution in the market offering connectivity for up to four 4K displays spanning a standard desk setups to enterprise class workspaces. Our Cayenne family, which has been successfully incorporated into several protocol adapters, is seeing new traction in notebook motherboard designs with native support for 8K resolution. As companies return to the office, we see an increased focus on flexible meeting room controllers using our technology. In addition, our universal docking solutions from DisplayLink solve many of the problems that can arise in hoteling and, as a result, continue to see strong demand. Lastly, to close out the IoT discussion, I'd like to give a brief update on our low-power edge AI initiatives. While still early in the cycle, we believe many devices in the future will continue to get smarter than they are today by incorporating machine learning and AI technologies on the device itself rather than relying on the cloud. We see opportunities and have already begun deploying advanced AI algorithms into many of our new products across all our markets, such as neural network-based fingerprint matching, advanced AI-based face detection in tablets and smartphones, and AI-assisted video compression algorithms. We are also seeing broad initial interest in our Katana platform, which is our standalone AI offering that targets low-power, battery-operated applications. It is our belief that many of these intelligent edge use cases will become a significant opportunity for Synaptics over the long term. Turning now to our PC products, we continue to benefit from growing demand as the notebook computer gets increasingly woven into our daily fabric as an essential productivity tool. As many companies focus on returning to the office, we expect to benefit from our leadership position in enterprise class notebooks. In the high-end consumer class, we are seeing Momentum Enforce and Haptics-enabled touchpads utilizing our Vulcan chipset. As previously discussed, our recent initiatives addressing the Chromebook market continue to be a greenfield growth opportunity for the company. Finally, let me give you an update on our mobile products. We are now in high volume production with our second generation OLED touch controller and are set to roll out a third generation, which will further extend our performance leadership. Our technical advantages have led to meaningful diversification of our mobile customer base, including an additional design win with a large Korean handset OEM, bringing our total with this customer to three, two of which have already begun for shipping. In addition, we continue to win the majority of new flagship designs using flexible OLED panels with Chinese handset OEMs. We have also made significant progress with our high-end OLED display driver products, having secured two wins with Chinese handset makers with expected production in calendar 2022. Overall, I'm extremely happy with the strength of our portfolio and quite optimistic about our prospects as we begin our new fiscal year. Despite the turmoil the semiconductor shortage has created, we find ourselves in an increasingly positive standing with our customer base, Our technology continues to drive design wins in the marketplace, and we've built a strong team ready to support our customers' needs. Now let me turn the call over to Dean to review our financial results and provide our outlook for the coming quarter.
Steve
Thanks, Michael, and good afternoon to everyone. I'll start with a review of our financial results for our recently completed fiscal year and recent quarter. then provide our current outlook for our fiscal Q1. For the full year fiscal 2021, net revenue of $1.34 billion was flat to the prior year of $1.33 billion. During the year, our mobile products declined, as previously discussed, driven by a large North American OEM, which was offset by significant growth in our focused IoT products and our PC products, which both grew double digit compared to the prior year. Gross margin for the company's products continued to expand with gap gross margin for fiscal year 2021 of 45.6% compared to 40.7% in the prior year, and non-gap gross margin of 53.6% compared to 43.7% in the prior year as we concentrated on the delivery of higher value products to our customer base. GAAP net income for the recently completed fiscal year was $79.6 million or $2.08 per diluted share compared to the prior year of $118.8 million or $3.41 per diluted share. Non-GAAP net income for the recently completed fiscal year was a record $316.4 million or $8.26 per diluted share, compared to the prior year of $207.2 million, or $5.95 per diluted share, a 53% year-over-year improvement. Revenue for the recently completed June quarter was $328 million, slightly above the midpoint of our guidance. Revenue was up 1% sequentially which is significantly better than our typical seasonality, which reflects an increased diversification of our business and end markets, and up 18% year over year with our IoT products delivering significant growth from both new and existing customers. IoT continues to be our largest product group, accounting for 50% of the revenue in the quarter, while PC accounted for 26%, and mobile accounted for 24%. Our IoT revenue was up 13% sequentially and up 143% compared with the year-ago quarter, as we benefited from acquisitions made last year. Removing the impacts for any acquisition-related strength, our organic IoT products were up nearly 30% year-over-year, as our design wind pipeline ramps into production. PC product revenue was down 14% sequentially and down 5% year over year, as many of our customers were constrained by a shortage in other components. Revenue from our mobile products was down 4% sequentially, as expected due to seasonality in this market, and down 35% year over year. During the quarter, we had one customer above 10% of revenue at 17%. For the June quarter, Our GAAP gross margin was a company record, 52.1%, which includes 16.9 million of intangible asset amortization and 800,000 of share-based compensation costs. GAAP operating expenses in the June quarter were 119.9 million, which includes share-based compensation of 22.3 million, acquisition and integration-related costs of $8.6 million, consisting of intangibles amortization, amortization of prepaid development costs of $2.5 million, and restructuring-related costs of $300,000. During the quarter, we incurred an impairment charge of $7.7 million on a prior equity investment in a small startup company. Our GAAP tax expense was $15 million for the quarter. In the June quarter, we had a GAAP net income of $19 million, or a GAAP net income of $0.48 per share. Now turning to our non-GAAP results. Our June quarter non-GAAP gross margin of 57.5% was a company record and at the high end of our guidance range. reflecting a continued strong mix as we prioritize our highest value products to customers. June quarter non-GAAP operating expenses were at the low end of our guidance range at $86.2 million, down $1.2 million from the preceding quarter as we continue to manage to responsible spending levels. As a result, our non-GAAP operating margin of 31.2% in the quarter was the company record. Our non-GAAP tax expense was $11.9 million for the quarter. We had non-GAAP net income in the June quarter of $86.6 million, an increase of 9% from the prior quarter, and an increase of 98% from the same quarter a year ago, and EPS of $2.18 per diluted share as our focus on profitable growth continues to drive positive earnings for our shareholders. Now turning to our balance sheet, we ended the quarter with $836 million of cash on hand, an increase of $80 million from the preceding quarter, driven by $105 million of cash generated from operations during the quarter, partially offset by the settlement of a small number of convertible note holders who elected to optionally redeem $19 million in principal value during the June quarter. Additionally, on June 1st, 2021, the company served notice to all convertible note holders of our intention to redeem in full any and all outstanding notes following the process outlined in our 2017 notes indenture. The company elected to redeem for cash consideration the full face value of the notes and settle any in-the-money value with shares issuable from the company's existing Treasury stock holdings. This process concluded on August 4, 2021, after the company's quarter end, and resulted in the issuance of approximately 3.5 million shares and the payment of approximately $506 million in cash consideration. As a result, as a reminder, each quarter we include these in the money shares into our fully diluted share count and have been incorporating them into our quarterly guidance. Therefore, they have been comprehended in our results where appropriate. Following this transaction, the company's balance sheet is extremely healthy. with gross leverage roughly one times adjusted EBITDA and net leverage approximately 0.8 times with the company's remaining debt maturing in 2029. Given our strong cash flow generation and improved balance sheet, the Synaptics Board of Directors have authorized the extension of our stock repurchase plan, extending its expiration for an additional four years and increasing the authorization by an incremental $400 million, bringing the new available authorization to $577 million. We will continue to deploy our capital in accordance with our priorities previously outlined. First, investing in organic growth initiatives. Secondly, pursuing inorganic means of expanding our product portfolio. managing our debt commitments in a prudent manner, and finally, continuing our share repurchase program to return excess cash flow back to shareholders. Receivables at the end of June were $228 million, and days of sales outstanding were 63 days. Our days of inventory was 53, up from last quarter, and ending inventories were $82 million. However, Inventory remains below our desired level due to continued supply chain constraints. Capital expenditures for the quarter were $5.6 million and depreciation was $6.1 million. Now turning to our outlook. We enter our fiscal year with strong customer demand for our products and increased visibility with more than 90% backlog coverage of our anticipated full-year fiscal 2022 revenues. We anticipate revenue for the September quarter to be in the range of $355 million to $385 million. Similar to last quarter, our backlog at the start of the quarter was above the top end of our guidance range as we continue to experience supply constraints that limit our ability to service our customers' full demand. We expect our revenue mix from IoT, PC, and mobile products in the September quarter to be approximately 51%, 24%, and 25% respectively. Our expectation incorporates our IoT products growing an estimated 65% on a year-over-year basis. significantly faster than the market. And as communicated during our last quarter's call, our mobile products bottomed in the June quarter and are anticipated returning to growth beginning with the September quarter. We continue our cautionary approach on our PC guidance, given the supply volatility this area seems to be experiencing. However, we believe the September quarter is likely to be up roughly 10% on a year-over-year comparison as enterprise class notebooks continue to perform well. I will now provide GAAP outlook for our September quarter, and we'll follow with our non-GAAP outlook. We expect our GAAP gross margin to be in the range of 52% to 53.5%. We expect our GAAP operating expenses in the September quarter to be in the range of $123 million to $128 million. which includes acquisition-related charges for intangibles and prepaid development cost amortization, share-based compensation, and restructuring costs. We also expect a one-time gap charge related to the early retirement of our convertible notes of approximately 8 to 9 million. We expect our 2022 gap tax rate to be approximately 20 to 25 percent. Finally, Our GAAP net income per share for our first quarter is expected to be in the range of $0.85 to $1.15. Now the non-GAAP outlook for our September quarter. We expect to maintain our non-GAAP gross margin momentum into the September quarter and be between 57% to 58%. which is ahead of all prior plans as we prioritize and deliver to a positive mix. We expect our non-GAAP operating expenses in the September quarter to remain consistent with the past several quarters and be in the range of $87 million to $90 million. We expect our non-GAAP net interest expense to be approximately $4.5 million in the September quarter. We expect our long-term non-GAAP tax rate for fiscal 2022 to continue to be in the range of 11 to 13%. Non-GAAP net income per diluted share for the September quarter is anticipated to be in the range of $2.45 to $2.75 per share on an estimated 40.5 million dilutive shares, which includes the shares issued as part of our redemption of the convertible notes. This wraps up our prepared remarks. I'd like to now turn the call over to the operator to start the Q&A session. Operator?
Operator
Thank you. As a reminder, to ask a question, you will need to press star 1 on your telephone. To withdraw your question, press the pound key. Your first question comes from the line of Raji Gill from Needham & Company. Your line is now open.
Raji Gill
Congratulations on great results. Michael, I was wondering if you could provide a little more clarity on the growth that you're seeing in IoT. In your guidance, as you mentioned in your prepared remarks, the IoT business is going to grow 65% on a year-over-year basis after phenomenal growth the year before, and significantly faster than the market. We're wondering kind of what's driving the growth rate in terms of specific end markets, What's driving it in terms of from a technological perspective? Any clarity there that's leading to that phenomenal growth in IoT?
Michael Hurlston
Hey, Rodney. First of all, thanks for the question, and thanks for the continued support. You know, I would draw your attention to two technology areas. I think the wireless, as we said, has just continued to really outperform IoT. That's across all three technologies, Wi-Fi, Bluetooth, and GPS. GPS doesn't get much attention, but we've done really, really well with that technology, as we said, and particularly in the wearables market. The other technical area that also encompasses a market that we haven't talked about is automotive. The automotive market is has been hot. We said in the prepared remarks that we're actually well ahead of plan there. We expect to hit $100 million run rate this year in automotive, which historically has been a small contributor for us. So we really like that business, and I think that's really fueling those two areas in particular, Raji, are fueling a lot of growth for us. And It's growth that we see, I think, continued and being sustainable for quite some period of time.
Raji Gill
Great. So auto is considered part of the IoT group, and so that's adding to the strong expectations. Yeah, that's right, Rajiv. Okay, great. And, Dean, on the gross margin, so the gross margin guidance, Again, you know, fantastic gross margin guidance is 57.5% growing sequentially. Is this mainly due to, you know, to mix shift? And when we're looking out, you know, over the next several quarters, the fact that you are, you know, pretty much at your long-term gross margin target, or I've surpassed it, actually, are there other levers that you intend to push, whether that's FAB consolidation targets, I mean, with your outsourced partners, or is there other considerations that you're thinking about in terms of margins?
Steve
Yeah, I mean, certainly we're really excited that we've gotten to and now slightly surpassed our model. The margins are largely due to mix. I mean, and Michael talked about his repair remarks, but we've also been talking over the last two years that we do intend to You sell our high market value products first and lead with those leading products first. And that mix and sort of mix within our own mentality here has sort of driven us a long way. There are other things I think we can do sort of longer term. Part of that has to do with our focus on introducing new products that are designed for higher gross margins. We've continued to talk about consolidating our supply chain partners. I would say with a lot of the supply constraints right now, that's probably not a near-term opportunity, but we do seek to be more strategic and more meaningful to our supply partners longer term, which we think results in better economics for both parties down the road.
Michael Hurlston
Yeah, I mean, Raj, you just add some color to what Dean said. I think that it has largely been driven by mix, as you theorized in your question. What we haven't done in terms of opportunity is really design for cost. Dean and I have played the hand that we got when we arrived, other than the acquisitions that we've added. But we now have products that are starting to get design, win, traction, and customers that are better from a cost basis, that we actually went out and designed these products with cost in mind. So I think that's going to be a lever that you're going to see play out. It's masked a bit at the moment because we are seeing cost increases from the supply chain. So our attention to detail on design for cost, you know, when we actually see that, it'll be hard to tell because, as I say, it's a little bit masked at the moment. But we do have a huge, huge attention now on die size, on manufacturing costs, etc.,
Raji Gill
All right, very good. Congrats again.
Michael Hurlston
Yeah, thanks, Roger.
Operator
Thank you. Your next question comes from the line of Anthony Stuss from Craig Hollow. Your line is now open.
Anthony Stuss
Hey, Michael. Hey, Dean. Mike, congrats as well. I'm curious, just, again, fantastic gross margins, 57.5%. With the component shortages, how much did that hold back your gross margins from being even better than 57.5% in the quarter? And then, Michael, for you, I'd love to hear a little bit more on the Chromebook space opportunity, how much content it is, and just how big of an opportunity it might be. And then I had a follow-up for Dean after that.
Steve
Yeah, hey, Tony, just thanks for the questions. One on how much has been a holdback in the current quarter, really because of supply constraints. Honestly, I would say there's not necessarily a holdback here. I mean, in fact, if anything, we're actually – conscious of the more conscious given our limited supply availability on the value delivering to customers. So we do look to make sure that we're prioritizing where we can our highest value products and where we can make the biggest impact to our customers and their needs. So I wouldn't call it a holdback.
Michael Hurlston
Yeah. And Tony, on the Chromebook, we're really coming off a very, very small base in Chromebook. I think there's a lot of noise in the Chromebook marketplace at the moment because it was red hot last year. Now it seems to be tailing off some. But we're coming off a position of almost no presence. We didn't have any of our products qualified on Chromebook. And we focused on that. We talked, I think, in the previous call about some design wins in that area. So we're upping our market share there. You're talking about a couple of bucks per Chromebook, but we're trying to consolidate share there a bit where we're at nothing today and trying to move up somewhat significantly on the share vector over the course of the year. So hopefully that addressed your question.
Anthony Stuss
It does. And just lastly, as a follow-up, I'm curious, your philosophical ideas on, you know, you have excess demand right now, so you're shipping your highest gross margin products. Do you either raise prices on your lower gross margin products, or would you ultimately even just walk away from some of that lowest gross margin going forward?
Michael Hurlston
Yeah, great question. And it's something that we toy with. I mean, we're in pretty competitive markets as it is. So our ability to go in and raise prices is challenged. Now, it's not to say that in certain cases we have been able to do that, passing on some of the very significant cost increases we've seen to our customers. But as Dean said, I think what has, if there's any benefit in the supply crunch, it's been this idea of prioritizing our most strategic customers and those that are giving us the highest value. So from a mix perspective, a mix within the mix, when we look at what we have available to ship, we're obviously prioritizing the products and the customers that deliver the highest gross margin.
Anthony Stuss
Awesome. Great job, guys. Thank you.
Michael Hurlston
Thank you.
Operator
Thank you. Your next question comes from the line of Chris Roland. from Susquehanna. Your line is now open. Hi, guys.
Chris Roland
Thanks for the question. I guess, first of all, if you could get a little bit more into supply bottlenecks, are they all the same? Is this bumping? Are there things that are more specific to your product line? How much of this is you know, kidding issues or, you know, customers' own specific problems, just any more details there would be great.
Michael Hurlston
Yeah, Chris, I mean, I think the headline is obviously wafer starts. That's where our biggest bottleneck is getting starts from the foundry partners. There are constraints elsewhere. We have isolated constraints in, as you said, in bumping and packaging in the back end, but certainly the long pole for us is wafer starts. If we're able to solve that, there's still constraints in the back end, so it's not a perfect world, but it's significantly better. We are seeing also now challenges around kitting. As you mentioned, we've seen some movement in our backlog as our end customers are more or less able to source the entire kit. And it makes it very, very challenging for us to really predict where we need to supply. Tony asked a question a minute ago about kind of the mix and higher and lower value products. We definitely have some challenges trying to predict in the end which customers are able to deliver the kit and which ones aren't.
Steve
Yeah, the only other thing I would say, you know, Chris, is where we are experiencing the highest growth, I mean, this is sort of in our IoT business, and we've talked about Wi-Fi, you know, really doing well, that's probably putting the most pressure on the supply chain.
Chris Roland
Great. Thank you. Also, I noticed you guys raised your internal inventories in the quarter. I'm wondering if that's to prepare for a seasonal ramp at what's traditionally been your largest customer there. Do you have visibility into, finally, what your content looks like there? Separately, You've now surpassed, well, you're at your long-term gross margin target, and you've well surpassed your op margin target. So are we going to get an update there, and where might those numbers go?
Steve
Yeah, so first on the inventory question, Chris. Yeah, so inventory is up a little bit quarter on quarter. It's a few specific products. I wouldn't characterize it as sort of a broad ability to improve our inventory. Although supply chain is sort of marginally improved in certain areas, it is to support a couple of specific customers and the backlog that we have sort of prepped with them. It is not to support our traditionally largest North American customer, just to clarify. And then maybe on the long-term model and surpassing around gross margin, then I'll hand it to Michael on your other question. So right now, we're actually not planning to update our long-term target at this point. I think it's actually a comfortable sort of range to be running the company. Obviously, we're going to push for every bit of dollar improvement and margins that we can. But I think at the high level, we're sort of operating the company in a construct that is very reasonable and very sustainable.
Michael Hurlston
And then, Michael, I don't know if you want to answer about the... Yeah, let me talk about the large North American customer. I mean, I think that we definitely have visibility into what it is. I think we talked a little bit about it on the last call in that we don't expect any touch business from them on a go-forward basis. In general, in Dean's remarks, he talked about mobile sort of hitting a bottom in the last quarter and now building out of that. And what that... signals really is that certainly with the large North American customer, we've gone through the entire transition. We've transitioned our LCD display driver to a point where we think that's kind of at its asymptote. Our touch business, obviously we had a big spike last year, but in the back half of the year, we didn't see a lot of business on that and we don't expect any going forward. So I think that with that particular customer, We're at a steady state. We feel good about that. And as Dean said in his remarks, in mobile in general, we see upside as we continue to prosecute wins in our touch controllers for Korea and for China, and then a further out opportunity that we talked about in OLED display drivers in next calendar year.
Operator
Great. Thanks, Michael. Thank you. Your next question comes from the lineup. Kevin Cassidy from Rosenblatt Securities. Your line is now open.
Michael
Thank you, and congratulations on the great results. I'm just wondering if you could discuss any changes in the set-top-box design activity, particularly considering the FTC settlement with one of your competitors.
Michael Hurlston
Yeah, hey, Kevin. We really haven't seen any meaningful change in the environment. I think that Broadcom went in and settled that case out very quickly. We definitely have talked about design wins in that business, and we think that we have reasonable level of traction in the market. But that level of traction really wasn't affected one way or the other by the Broadcom announcement, the Broadcom and the squabble with the FTC.
Michael
Okay. Great. Thanks. And maybe if you could just – you mentioned all the edge AI applications. Maybe could you just give a couple of examples of what the AI function is doing in the device?
Michael Hurlston
Yeah, where we're trying to apply, there's a lot of action in voice, and that would be like in the Alexa device, for example, prosecuting simple voice commands at the edge rather than sending a, hey, Alexa, back to the data center and cluttering the data center up with a bunch of, hey, Alexas. What we're trying to do is a unique angle, and that's actually video rather than voice. Voice, there's some really strong players in that area. We're actually taking a different bet and trying to solve some video-related problems. A good example of that is people counting. So now a lot of folks, retailers, store owners, want to know how many people are in a store, whether it's to monitor foot traffic or... to kind of keep track of how many people and what the social distancing is within a shop, they want to know how many folks are in their particular space. And our low-power Edge AI application is able to do that, able to do that calculation there real-time, so there's a real-time, low-latency, low-cost way to do it, rather than sending things back to the data center. So our... Our take on this market is more around video and vision than it is around voice. And we think that we've got the right ecosystem and the right set of partners to enable us. This is not a today market. I mean, this is going to be something that's going to take a couple of years to play out. But it's an investment area for us. And it's one in which we're probably the largest player that's got a real entry in this area. Okay, great. Thank you. Thank you. Good question.

Thank you. Your next question comes from the line of Carl Ackerman of GoWin. Your line is now open.
Carl Ackerman
Yes. Thank you, gentlemen. Two questions, if I may. Just in IoT, many of your peers have noted supply constraints across Wi-Fi and Bluetooth products. yet your performance for this quarter and your implied outlook does indicate you're performing better. I guess how much of the sequential improvement you're guiding to in IoT is coming from access to more substrate supply, and perhaps how much may be driven by brand-new design ramps that often see larger order builds in initial quarters of ramps?
Michael Hurlston
Yeah, I mean, we are, Dean said it just a minute ago in response to another question, this is probably our most challenging supply area. I mean, the numbers, frankly, could be quite a bit better than they are if we had unlimited access to supply. And that is driven by the fact that we're winning in the market. We're getting a lot of new design wins across Video applications, wearables, it really runs the gamut for us. But because this is a new business to us, we didn't forecast the wafer starts. And as a result, we're coming off a zero base. And the way the foundries are working is they start you at your baseline from the previous year, and you go up from there. So this is absolutely our most supply-constrained area, as Dean alluded to. Carl, we could be doing quite a bit better, as I said, if we had unlimited access to supply in the wireless arena.
Carl Ackerman
That's very helpful. I guess a two-part question for my last one, if I may, just to follow up on that comment. Given the rapid increase in automotive revenue, could you discuss whether those design wins are locked in for the duration of the vehicle platforms? And then secondarily, could you discuss whether the design win that you're seeing at your Korean customer, your third one, is broadening from flagships to mid-range offerings and whether you have visibility into multi-generational designs? Thank you.
Michael Hurlston
Yeah, let me start with automotive. I mean, I think just like any provider in automotive, once you get in, you're pretty much locked in for the duration of the design. So certainly our visibility is a longer visibility in that business than in any other businesses that we participate, and we feel good about the sustainability of each of the design wins that we talked about in the prepared remarks. We've been able to win in that market by uniquely combining touch and display solutions, and that combination is a differentiated combination that's given us a nice technical advantage with the auto OEMs and then the LCMs that make the displays for the cars. The second part of your question was around Korea. Where I'd say we are there is sort of sub-flagship, and to your point, then dropping down into more mass market types of phones. So we certainly haven't cracked the very, very highest end of that yet, and that's not unusual because we're not yet a proven supplier. We've just started production, as we said in the prepared remarks. So We feel pretty good about our ability to prosecute more with that customer, and that runs from high to low. And even as we've scaled down, because they're pushing flexible OLED down in their SKU stack, we haven't seen degradation in gross margin, even as those products have come down into sub-flagship and lower types of SKUs.
Carl Ackerman
Very helpful. Thank you. Thanks, Carl.
Operator
Thank you. And again, if you would like to ask a question, please press star 1 on your telephone. Your next question comes from the line of Ambrish Srivastava of BMO. Your line is now open.
Ambrish Srivastava
Hi. Thank you very much. I just wanted to come back to the gross margin, guys. Last quarter, you were pretty articulate many times when you were asked about the margin level and the dynamics. seem to be the IoT businesses is continuing to do better. So I'm just struggling with why should there not be a sixth handle very soon to the margin profile? Because IoT should continue to grow in absolute dollars. So is it just your natural being conservative, as you have been and you have over-delivered, not only on the cross-margin front, but on many fronts. So just kind of help us understand the level of conservatism on the margin side? Because the dynamics seem to be just exactly in favor of what has been going on for the last several quarters.
Steve
Yeah, good question, Ambrish. So I think in general, sort of what's been happening is we've been on this two-year journey of delivering higher value products to the marketplace. Generally speaking, this IoT set of products is are higher valued in the market. And as that continues to grow, our margins continue to expand, like you rightly pointed out. But I would say there's two factors. One, in the near term, we continue to deliver to higher IoT growth rates, which continue to push up our gross margin mix. Here in the near term, that continues. As we're guiding into the again, a strong IoT, again, a strong gross margin. So I think here in that near term, you would continue to see the strength. But I would just remind you sort of longer term, you know, it's not an IoT-only business. So we do intend to growth all three product areas of our portfolio. We think there's organic growth opportunities within all three. And what we're doing is striking a balance to continue to grow gross margin in its aggregate, but then also move the top line forward and therefore dropping everything to the bottom line. So as all three buckets continue to move forward and find that balance, you're sort of finding this high fifties, you know, sort of a balancing act, if that makes sense, Ambrish.
Ambrish Srivastava
It does. It does. I have a followup on the disability, um, If I heard it correctly, you said you have 90% booked for the full year. Is that what you said, Dean?
Steve
Yeah, that's what we said. We have 90% or better booked for the full year. That's right.
Ambrish Srivastava
How would you compare that with, you know, you have obviously only been there a couple of years, but just in terms of what normal visibility would be, and then more importantly, we're hearing about long-term agreements from so many companies just because there isn't enough supply. How much of that would you consider characterized for us is covered by non-cancellable or long-term agreements? Thank you.
Steve
Yeah, so I think there's several parts in that one. First, around visibility. We have much longer visibility, close to four quarters, than we typically would. You know, typically the business would have more like one to two quarters of visibility, and sort of with the extended lead times that we've asked customers to give us additional visibility and, of course, extended lead times from our suppliers, right, it's sort of forced everyone to play nicely and sort of have a combined set of trajectories that everybody's forecasting. We have engaged a subset of our suppliers in longer-term agreements. really at the behest of our customers on, you know, getting the supply. They see the design win ramps that they need. We've collaborated with our customers to actually enter into, you know, secured supply on their behalf. And then the other one around, you know, your backlog and cancelability, et cetera. A good amount of our backlog comes with some sort of limitation around a customer's ability to cancel or reschedule. So not only is there some limitation around what customers are sort of allowed to do contractually, but also everyone's clamoring and actually trying to get accelerated supply where we can. So we feel pretty good about the coverage and the visibility that we have.
Ambrish Srivastava
Great. Thanks. Thanks for all the details, Dean. Yep.
Steve
Thanks, Ambrish.
