Douglas DeLieto (VP of Investor Relations)
Thanks very much. Hello, everyone. Welcome to Qorvo's Fiscal 2023 Third Quarter Earnings Conference Call. This call will include forward-looking statements that involve risk factors that could cause our actual results to differ materially from management's current expectations. We encourage you to review the safe harbor statement contained in the earnings release published today, as well as the risk factors associated with our business in our annual report on Form 10-K filed with the SEC, because these risk factors may affect our operations and financial results. In today's release and on today's call, we provide both GAAP and non-GAAP financial results. We provide this supplemental information to enable investors to perform additional comparisons of operating results and to analyze financial performance without the impact of certain non-cash expenses or other items that may obscure trends in our underlying performance.
During our call, our comments and comparisons to income statement items will be based primarily on non-GAAP results. For complete reconciliation of GAAP to non-GAAP financial measures, please refer to our earnings release issued earlier today, available on our investor relations website at ir.qorvo.com under Financial Releases. Joining us today are Bob Bruggeworth, President and CEO, Grant Brown, Chief Financial Officer, Dave Fullwood, Senior Vice President of Sales and Marketing, and other members of Qorvo's management team. With that, I'll turn the call over to Bob.
Bob Bruggeworth (President and CEO)
Thanks, Doug, and welcome everyone to our call. Qorvo delivered fiscal third quarter revenue and EPS above the midpoint of our outlook provided during our November 2nd earnings call. In high-performance analog, quarterly revenue reflected year-over-year growth in defense, broadband, and power. Our power business posted a strong quarter with robust design activity for our silicon carbide power devices. Offsetting this were power management markets with consumer exposure and infrastructure where customers are working down elevated inventory levels. In our connectivity and sensors group, the quarter reflected lower-end market demand and channel inventory consumption for Wi-Fi products, partially offset by strength in automotive. Design activity was strong across customers and products, including ultra-wideband, Matter, and sensors. Use cases continue to proliferate that benefit from precision location, indoor navigation, seamless connectivity, and enhanced human machine interfaces. Lastly, in advanced cellular, Qorvo participated broadly across customers' portfolios.
The macro environment weighed on overall smartphone volumes across customers and revenue reflected channel inventory consumption within the Android ecosystem. Design activity continued to be strong across customers and product categories and supports year-over-year content gains at our largest customers. Let's turn to some quarterly highlights. In high-performance analog, Qorvo began sampling a radar power solution that combines a high voltage power conversion PMIC and silicon carbide power switches to control a GaN RF power amplifier. The solution reduced the size by up to 30% in AESA radar systems while expanding Qorvo's content opportunity. We also expanded our SHIP state-of-the-art RF packaging contract with the U.S. government to develop multi-chip modules that combine digital optical devices with Qorvo's mixed signal RF. In aerospace, we delivered a multi-chip solution that includes Qorvo's high-frequency block filter as well as a GaN PA for low orbit satellites and other applications.
The solution supports cellular satellite links, and we have secured new designs. The opportunity for Qorvo is notable given the trend in defense and aerospace applications of one to many. That means rather than one jet, there will also be many drones. Rather than one geo satellite, there will also be many LEO satellites. At the same time, new capabilities are being added to existing platforms that require increased semiconductor content and higher density and more advanced packaging, all areas where Qorvo is strong and is investing to advance the technology. In cellular infrastructure, we commenced pre-production shipments of our first integrated PA modules or PAMS to a Tier 1 European infrastructure OEM for 5G massive MIMO base stations. We also began sampling our next generation PAM, which delivers market-leading efficiency for 5G massive MIMO installations to the leading European infrastructure OEMs.
For broadband infrastructure applications, we sampled a CATV power doubler amplifier that maintains linearity and extends bandwidth to enable higher throughput DOCSIS 4.0 capabilities with industry-leading power efficiency. Deployments of DOCSIS 4.0 are scheduled to begin this year. Qorvo is very well positioned as the industry leader. In CSG, we expanded our Wi-Fi content at a Korean-based smartphone OEM to include Wi-Fi 6E and Wi-Fi 7 designs. We ramped Wi-Fi 7 FEMs for access points and routers for our smart home ecosystem customer. We also commenced sampling 5GHz and 6GHz filters. These filters leverage Qorvo's next generation BAW process and enable worldwide Wi-Fi 7 frequency coverage. There is increase in customer interest related to Multi-Link Operation, which is a key attribute of Wi-Fi 7 and enables higher throughput and lower latency.
Lastly, we began volume shipments of MEMS-based sensors enabling an enhanced HMI experience in True Wireless Stereo earbuds. Qorvo sensors were selected to replace legacy capacitive touch sensor technology. Design activity for our sensors continues to be strong across markets, including automotive. We are working with leading automotive tier ones and have secured automotive smart interior design wins in more than 25 vehicles. In advanced cellular, we secured multiple design wins across Android OEMs in support of 2023 devices. During the quarter, we commenced the production ramp of multiple components for the leading Korea-based smartphone OEM's flagship platform. We have increased our content significantly year-over-year. We are broadly serving this customer across our portfolio and continue to support the migration of their mass market phones to integrated 5G solutions.
At a U.S.-based Android OEM, we were selected to supply multiple solutions, including ultra-wideband, antenna tuning, and BAW-based antenna-plexing in support of their 2023 smartphone launches. Lastly, Qorvo was recognized by multiple customers. We were presented with Honor's 2022 Golden Supplier Award, and we received quality awards from Vivo for discrete switches and amplifiers and highly integrated solutions. Before handing the call off to Grant, I wanna make a few high-level comments to frame our outlook, both in the near term and further out. At our largest two customers, we are very confident in our ability to grow year-over-year content, and that includes this year. In 2023, we expect growth in BAW-based content as well as other content growth. Equally important, we enjoy a range of opportunities across all of our customers in the future years.
Qorvo is supporting the highest volume flagship phones while supplying integrated 5G solutions as mass market portfolios migrate to 5G. Fewer than half of the Android devices were 5G in 2022, and the migration to 5G is expected to extend over many years. We are unique in advanced cellular in the breadth of our customer exposure and in the depth of our product and technology offerings. Our long-term view of ACG continues to be mid to high single-digit growth driven by multiyear content gains. In particular, we see expanding market for our BAW technology. Productivity gains in our Richardson, Texas fab have enabled a doubling of our BAW output. We intend to put that to good use as we continue to capture designs and grow our BAW content in flagship phones. We expect the long-term growth rate of HPA and connectivity and sensors to outpace advanced cellular.
Our view for HPA is double-digit growth, and in CSG, we expect growth in the strong double digits. Key growth areas supported by recent wins with silicon carbide devices, NEVs and solar inverters, MEMS sensors and notebook track pads and automotive smart interiors, and ultra-wideband in automotive and Android devices. These and other investment businesses are securing new designs that extend our opportunity in large growth markets. In the near term, the team is performing exceptionally well while navigating extraordinary events. Factory loadings have been reduced, and we are bringing down channel inventories. We are also actively managing the expense line while sharpening our focus in support of targeted growth. We are working to accelerate revenue related to our Omnia BAW-based biosensors by exploring options for the associated Omnia test hardware, meaning the Omnia desktop test unit and cartridges that contain our BAW biosensors.
The technology has been proven commercially, and we are engaged with a diverse set of customers. Qorvo remains at the forefront of connectivity, sustainability, and electrification. We enjoy exceptional customer relationships, and we are a key enabler of future architectures. These architectures continue to favor higher levels of performance, integration, and functional density to deliver the successive improvements in each market's next generation's products. Our customers value Qorvo's best-in-class products and technologies, and we are securing broad-based design wins in high-growth markets. As volumes recover, we are positioned to deliver long-term growth and robust free cash flow. With that, I'll hand the call off to Grant.
Grant Brown (CFO)
Thanks, Bob, and good afternoon, everyone. As a reminder, our references today will be to our three operating segments, high performance analog or HPA, connectivity and sensors group or CSG, and advanced cellular group or ACG. In our upcoming 10-Q, we will provide historical financial information that reflects these operating segments. Additional historical information will be made available in our fiscal 2023 10-K to be filed this May. I'll now turn to our latest quarterly results. Revenue for the third quarter of fiscal 2023 was $743 million, $18 million above the midpoint of our guidance. We enjoyed relatively strong performance in automotive, broadband, defense, and silicon carbide power devices. However, elevated channel inventories and weak end market demand pressured revenue and order activity across all three operating segments.
Looking at each operating segment individually, HPA revenue of $155 million in the quarter compares to revenue of $182 million in the same quarter last year. In HPA, growth in areas such as defense and silicon carbide power devices was offset by inventory consumption in the 5G base station market and softness in consumer-facing markets like SSDs and battery-powered tools. CSG revenue of $97 million in the quarter compares to revenue of $158 million in the same quarter last year. This reflects weakness in end market demand for Wi-Fi products and channel inventory consumption. ACG revenue of $491 million compares to revenue of $775 million in the same quarter last year. This reflects lower smartphone unit volumes and channel inventory digestion within the Android ecosystem.
On a non-GAAP basis, gross margin in the quarter was 40.9%. Gross margin fell sequentially due to lower factory utilization and higher inventory related charges, including a quality issue at a supplier. Non-GAAP operating expenses in the quarter were $206 million, $19 million lower than our guidance and down $8 million versus last year due to OpEx discipline, the timing of product development spend, and lower employee related expenses, including incentive-based compensation. In total, non-GAAP operating income in the quarter was $99 million or 13% of sales. Breaking out operating margin by each segment, ACG was 20%, HPA was 19%, and CSG was negative 32%. Non-GAAP net income was $77 million, representing diluted earnings per share of $0.75, which was at the high end of our guidance range.
Free cash flow was $203 million. Capital expenditures were $34 million. We repurchased approximately $200 million worth of shares during the quarter. The rate and pace of our repurchases is based on our long-term outlook, low leverage, alternative uses of cash, and other factors. Turning to the balance sheet, as of quarter end, we had approximately $2 billion of debt outstanding with no near-term maturities and $919 million of cash and equivalents. Our net inventory balance ending the quarter was up slightly at $857 million. Turning to our current quarter outlook, we expect quarterly revenue between $600 million and $640 million, non-GAAP gross margin of approximately 41% and non-GAAP diluted earnings per share in the range of $0.10 to $0.15.
Our current view reflects ongoing demand weakness across end markets, as well as our expectations for further consumption of channel inventory. We continue to expect sales to Android smartphone customers will increase sequentially in the March quarter. For historical reference, the March quarter revenue in fiscal 2022 for each of ACG, HPA, and CSG was $777 million, $211 million, and $179 million, respectively. At the volume levels assumed in our guidance, we expect Qorvo's inventory position will decline in March but remain elevated. In terms of channel inventory, the picture has begun to improve. For example, total channel inventory for our components in the Android ecosystem was reduced by over 20% in the December quarter. We expect continued improvement this quarter and anticipate the channel to normalize later this calendar year.
We are actively working with customers to consume channel inventories, and in doing so, we expect production levels to remain compressed. This will lead to continuing underutilization charges related to inventories, which will weigh on gross margin during fiscal Q4 and carry into next fiscal year. We project non-GAAP operating expenses in the March quarter will be up approximately $20 million sequentially due to the timing of product development spend, seasonal payroll effects, and other employee related expenses. Below the operating income line, non-operating expense will be approximately $15 million, reflecting interest paid on our fixed rate debt, offset by interest income earned on our cash balances, FX gains or losses, along with other items. Our non-GAAP tax rate for fiscal Q4 is expected to be consistent with fiscal Q3.
The rate remains elevated due to the absolute level and geographic mix of pre-tax profits, including FX related gains within high tax jurisdictions, as well as the impact of a U.S. tax law change related to R&D capitalization, among other factors. With regards to operations, I want to highlight the outstanding progress our teams have made in terms of productivity gains. We continue to make improvements in product development, filter design, process engineering, factory planning, manufacturing efficiency, and many other areas. To date, these gains have significantly increased our effective BAW capacity. As Bob indicated, the progress continues. Looking forward, we can double our BAW capacity in the Richardson facility versus our current maximum theoretical thresholds today. Increasing the throughput of an existing asset not only reduces cost, but can reduce complexity within the factory network as production is consolidated.
The BAW productivity gains in our Richardson facility allow us to achieve our long-term growth goals across all of our customers, including the most demanding BAW-based placements. As a result, we have decided to sell our Farmers Branch facility. We're in the early stages of marketing the site, initial interest has been encouraging. For reference, the site has been incurring approximately $12 million of non-GAAP COGS per year. We are also evaluating strategic alternatives for our biotechnology business to accelerate and maximize its potential value. The Omnia platform, which is based on our BAW sensor technology, has demonstrated significant promise as a diagnostic testing solution. The biotechnology unit currently resides in our CSG segment. While the revenue impact from a transaction would be negligible, it would reduce total expenses by approximately $32 million per year.
At this stage, it's too early to comment on the eventual outcome, timing, or potential valuation. These actions will sharpen our focus and resources on the many growth drivers across our three operating segments. Our long-term outlook is positive, and we're well-positioned to weather current macroeconomic challenges. Product performance requirements continue to increase in our end markets. Sustainability initiatives underscore the increasing global reliance on power efficiency, and connectivity and electrification trends are accelerating worldwide. We have diversified our opportunities across markets, customers, and product categories while maintaining our commitment to technology leadership, portfolio management, productivity gains, and reduced capital intensity. This has supported strong financial performance during a challenging environment and has positioned us for long-term, increasingly diversified growth. At this time, please open the line for questions. Thank you.
Operator (participant)
Thank you. We will now be conducting a question-and-answer session. If you would like to ask a question, please press star one on your telephone keypad. A confirmation tone will indicate that your line is in the question queue. You may press star two if you would like to remove your question from the queue. For participants using speaker equipment, it may be necessary to pick up your handset before pressing the star keys. We ask that you limit to one question and one follow-up. One moment please while we pull for questions. Thank you. Our first question is from Toshiya Hari with Goldman Sachs. Please proceed with your question.
Toshiya Hari (Managing Director and Equity Analyst of US Semiconductor and Semiconductor Capital Equipment)
Hi, good afternoon. Thank you so much for taking the question. You gave really good color on channel inventory, but was hoping to ask a follow-up there. So channel inventory as it relates to Android, I think you said was down more than 20% in the December quarter. I guess, how do you see that evolving over the next couple of quarters? I guess more importantly, on the non-Android side or the iOS side, what's your current assessment of channel inventory and how that plays out over the coming quarters?
Dave Fullwood (SVP of Sales and Marketing)
Yeah, this is Dave. I'll answer that one. First, we're not gonna comment on the iOS side of the inventories, and Grant already mentioned the Android. I think when we look at the overall channel inventories, and when we refer to channel inventories, we're talking about all of our components that are out, whether they're in our distributors or at the end customers. You know, on balance overall, it's down about 20% across the entire business, not just within the Android ecosystem. If you look just within our distribution channel, it's down about a third in the December quarter. As Grant mentioned, we still have a ways to go there. We expect to continue reducing that across this quarter and then into the early part of FY 2024.
Toshiya Hari (Managing Director and Equity Analyst of US Semiconductor and Semiconductor Capital Equipment)
Got it. Then as my follow-up on gross margins, you know, you're guiding the March quarter to, I guess 40%-41%, which is essentially flat sequentially. Can you speak to where your utilization rates are today? As you continue to, you know, work down inventory and the overall industry continues to work down inventory, you know, what cadence should we be thinking about for the rest of the calendar year? Do you think you can exit kind of in the high forties or even close to 50% calendar 2023, or is that, you know, a little too optimistic at this point? Thank you.
Grant Brown (CFO)
Sure. Toshiya, thanks for the question. I'll touch on margins here, and I'll try to cover all of it, both in Q3 and then looking beyond that into fiscal 2024. For fiscal 2023, the primary driver of gross margin continues to be underutilization and inventory-related charges. In Q3, it accounted for about 920 basis points of headwind, or in that neighborhood, and it's expected to remain there in the March quarter, hence the flat gross margin guidance. Inflation across direct costs were approximately 80 basis points in Q3, and again, expected to remain there in Q4. As we stated earlier, in Q3, there was a supplier quality issue, representing approximately 30 basis points of headwind in our Q3 period. Kind of walking through that Pareto, you can see the dominant factor is clearly underutilization.
To your question about getting back to 50%, It's unlikely in fiscal 2024, although it depends on your view of the macroeconomy and a number of other variables. However, underutilization, you know, creates a lingering impact due to timing. As volumes fall, those inventory balances will reflect higher per unit costs. And simply put, you know, fewer units moving through a fixed cost factory collect more cost per unit. We saw this heading into the December quarter, and it'll carry forward into fiscal 2024. The rate at which that high cost inventory flows through the P&L will obviously depend on variables like our future utilization or product mix, including a ramp of revenue over the course of fiscal 2024.
Although the precise timing is uncertain, the reduction in channel inventories is very encouraging, and it's a necessary first step. If I do look out over the course of fiscal 2024, I could see potentially that 920 basis points of margin get cut in half, again, subject to your view of the revenue trajectory throughout the year.
Karl Ackerman (Managing Director of Semiconductors and IT Hardware Equity Research)
Very helpful. Thank you.
Operator (participant)
Our next question is from Karl Ackerman with BNP Paribas. Please proceed with your question.
Karl Ackerman (Managing Director of Semiconductors and IT Hardware Equity Research)
Yes, thank you. Good afternoon. I was hoping, you know, you could discuss a little bit more commentary regarding your outlook. You certainly gave much commentary across the P&L for March. Within that outlook, could you discuss the order of magnitude decline between your segments? I'm just trying to have a better understanding of what's occurring, I guess, in the legacy IDP segment, which appears driven by some maybe some inventory overhang within Wi-Fi, IoT, and maybe telecom infrastructure. Then as you address that question, what are your assumptions for your mobile revenue in China in the March quarter, which I believe was guided to 10% in December?
Grant Brown (CFO)
Sure. Let me start with our view of the segments in the March quarter. You know, if we go back to, you know, comparing our current March guide to our thoughts last November, there's a bit of variance in HPA and CSG. You know, instead of flattish, there'll be rather modest declines there in dollar terms for our guide. Biggest driver, of course, is ACG. If you consider the size of our largest customer relative to ACG revenues in December, you know, and that customer, excuse me, is seasonally down in March and June, you know, it's a sizable headwind, and that really dictates the path of our top line.
In terms of our China-based smartphone OEM revenue, it came in largely in line, just a bit above 10%.
Karl Ackerman (Managing Director of Semiconductors and IT Hardware Equity Research)
Understood. I guess just maybe just to follow up on that with regard to the China Android OEMs, it sounds like that came in a little bit better. Should that remain at a similar level of revenue on a mixed basis in March? It sounds like that's gonna be improving. I guess, you know, if to the extent you could talk about the recovery process or how you see the recovery process for the balance of the year, I guess the question that I would like to understand is, you know, given some of the new the opportunity in premium tier Android flagships you've announced this today, it's certainly great to hear.
I guess if you could discuss the, you know, the level of confidence you have in demand returning for mid-tier handsets for the balance of the year would be super helpful because I ask because two very large Korean memory OEMs this week indicated the smartphone market could bifurcate between good demand for flagships, yet weaker demand for lower and mid-tier models. If you could just kind of comment on, I suppose the production approach and your design approach for those markets if they do bifurcate would be very helpful. Thank you.
Grant Brown (CFO)
Sure. If I decompose it, maybe I'll start, and I'll let Dave tackle the different tiers of handset models. In terms of revenue, as we look forward into the guide, we would expect our China-based smartphone OEMs in dollar terms to be roughly flat, but overall, our Android revenue to be up. You know, as we look maybe deeper into fiscal 2024, without going into too much detail or attempting to guide at this point, given the overwhelming impact of macroeconomic factors, I can shape it a bit for you and provide some of the drivers. In terms of revenue beyond the March quarter, we would expect June to be roughly flattish. Could be a bit higher or a bit lower, depending on your view of the economy or China's reopening.
We don't have, terribly ambitious expectations for the reopening at this point. We're playing it a bit conservative with our view. From there, I would expect September to see significant sequential growth, and then December and the March 2024 quarters to be back to strong annual growth, from there. Dave, I don't know if you mind commenting on the tiers.
Dave Fullwood (SVP of Sales and Marketing)
Yeah. As Bob mentioned in his remarks as well, you know, we're seeing really nice content growth in the premium tier. We're well represented there. Of course, we've always been well represented in the mass tier as well of 5G. There's still a lot of room to go in terms of conversion to 5G. The rate and pace of that may not be as quickly as we would have liked, but it's still a lot in front of us. We expect to see, you know, that mass tier still moving to 5G over time.
Karl Ackerman (Managing Director of Semiconductors and IT Hardware Equity Research)
Very helpful. Thank you.
Dave Fullwood (SVP of Sales and Marketing)
Our next question is from Gary Mobley with Wells Fargo Securities. Please proceed with your question. Mr. Mobley, please check if your line is muted.
Gary Mobley (Executive Director and Senior Analyst of Semiconductors)
Guys, can you hear me now?
Bob Bruggeworth (President and CEO)
Yes, we can, Gary.
Gary Mobley (Executive Director and Senior Analyst of Semiconductors)
My apologies. I want to start out by asking for some clarification, on what Grant just mentioned regarding the sequential revenue comps and year-over-year growth, you know, looking into, the first half of next calendar year. Was that in reference to CSG or the business overall?
Bob Bruggeworth (President and CEO)
it was the business overall.
Gary Mobley (Executive Director and Senior Analyst of Semiconductors)
Okay. Thank you for that. Any change in view on the purchase commitments from your foundry and suppliers? Do you anticipate utilizing all those commitments or might we be looking at some additional write-downs there just given the dynamics?
Grant Brown (CFO)
Yeah, no change to our view. As you'll remember, we restructured the agreement last quarter to better align our view of demand with supply and are working with that partner on an ongoing basis.
Gary Mobley (Executive Director and Senior Analyst of Semiconductors)
All right. Thank you, Grant. Thanks, everybody.
Grant Brown (CFO)
Thank you, Gary.
Dave Fullwood (SVP of Sales and Marketing)
Our next question is from Edward Snyder with Charter Equity Research. Please proceed with your question.
Edward Snyder (Co-Founder and Managing Director)
Thanks a lot, guys. Several questions actually. First off, it sounds like the competitive environment, especially in China and maybe in Samsung, is getting much more difficult. We've gotten lots of feedback of Maxscend being a major competitor in switches, fielding high-band modules, competing in ultra-wideband, which wasn't the case two years ago. I know they've been out there slugging away for some time, and now it seems like maybe the political environment in China is favoring them more. First off, are you seeing that? Are they becoming more aggressive? Number two, are the margin expectations for the Chinese anywhere close to what we've come to normally expect from your normal, you know, Western competitors? If not, wouldn't that affect ASP? Is it affecting ASP or should we expect the ASP to decline?
I'm gonna have a follow-up, please.
Bob Bruggeworth (President and CEO)
Yeah. Hi, Ed. Thanks for the question. You know, as far as the Chinese competitors, they've always been there. We've always seen them. I think what is overriding everything is the highly integrated modules that require premium filter performance, particularly for those that are being exported, as well as for within the China consumer market. So, you know, we still feel very good about our position there with our integrated modules, whether it's ultra-high band, what we're doing, obviously, you know, with mid-high as well as, you know, the work that we've done, improves significantly the performance and cost in our SAW filters for low-band paths. So we feel real good about how that's positioned. And from a pricing perspective, you know, we haven't seen significant changes there, Ed. I think there's some areas we're actually raising prices.
in some areas, yeah, there's a little bit of competition, but we always have that. We haven't really seen a change in the market.
Edward Snyder (Co-Founder and Managing Director)
Great. Then on that same note about increasing, it sounds like the MEMS business is, I know you've been working on MEMS forever, and now they're showing up. The ASPs, I know you're looking to field them as tuners, and we've tracked that business pretty closely from the time, but it sounds like you might be seeing a significant increase in ASPs, to the extent that you want the industry starts adopting MEMS. Maybe if I can flip that over, it sounds like since Samsung's reorganized the handset division, now they're using open market modules, the actual content in ASP for those modules seems to have dropped significantly, whether it be the mid/high band or the low band.
I'm just talking about their flagship, of course, 'cause the Master is a big step up going to modules. I'm just trying to get my arms around the, what the overall, let's say year-over-year or year over two years ago content picture looks like from the Koreans' point of view in terms of redesigning that front end, and then what kind of trends in products like MEMS do you have that are bucking that trend? Thanks.
Bob Bruggeworth (President and CEO)
Yeah. Thanks, Ed. I'll take the MEMS and let Dave speak a little bit more about your comments about the standard products that we've been selling that are highly integrated, integrating in all the filters. As far as MEMS goes, we're still very early on in that. Ed, as far as the RF MEMS go, as you know, we've been working on that through the acquisition of Cavendish Kinetics and really just beginning to roll that out. Yes, they are paying for that. We don't expect that to go, you know, broadly and replace all of our antenna tuners. It gets you a DB or so and, you know, people that are willing to pay for it will pay for that. That technology is costs a little bit more per function, but you pick up a significant improvement in the performance.
Second, you know, we're also, our pressure sensor MEMS, you know, we're doing extremely well there. I commented in my opening comments about being in, you know, over 25 different vehicles. People are starting to implement it in track pads across all of the major OEMs are now looking at it. We're engaged with them. You know, we're just seeing that proliferate into watches and various other devices. It's very early on also in its, you know, life cycle. We feel real good about that. I'll let Dave speak a little bit about your question about some of the Korean manufacturers and what we're seeing there.
Dave Fullwood (SVP of Sales and Marketing)
While the architectures are similar, especially that particular customer that you mentioned, they're still very demanding from a performance standpoint. They have their requirements and you have to meet their requirements to win that business. We're very focused on that. We work very closely with them on the advanced architectures, you know, years in advance to meet their needs. I wouldn't think of it necessarily as a standard product. It's still very demanding sockets.
Edward Snyder (Co-Founder and Managing Director)
Great. Thanks.
Operator (participant)
Our next question is from Vivek Arya with Bank of America. Please proceed with your question.
Vivek Arya (Managing Director and Senior Research Analyst)
Thanks for taking my question. On the first one, you know, gross margin and then how your balance sheet inventory affects that over time. You mentioned gross margin, I think 41%, for March, and if June sales are flattish, I imagine gross margins are gonna probably flattish also. I heard that you could recover about half of the 900 basis points of underutilization, suggest gross margin somewhere in the mid-40s in the back half. How do I align that with the inventory that you have on your balance sheet? You know, where do you see it going over time, and does that impact how the gross margin progression happens in the back half of the year?
Grant Brown (CFO)
Hey, Vivek. Thanks. This is Grant. I'll take your question. Yes, you've got it in terms of gross margin, and the answer on inventory is rather simple, right? As that inventory begins to get sold and flow through cost of goods sold, it'll drag with it those higher costs per unit associated with underutilization. I would expect inventories to trend down over time, you know, subject to normal seasonal ramps at large customers where we do have to build inventory in advance of those sales. Over time, it will come down, again, offset by some of those, growth-oriented, builds that we do at seasonal periods of the year.
Vivek Arya (Managing Director and Senior Research Analyst)
Grant, the reason I ask the question is because I heard before on the call that you think channel inventory normalizes later in the calendar year. I'm hoping I got that right. If channel inventory doesn't normalize until later, how will your balance sheet inventory start to get back to more normal levels?
Grant Brown (CFO)
They're not necessarily sequential. You know, they can happen simultaneously, depending on the level of demand. Although you're correct, I think the first stage of that would be a reduction in the channel inventories, increase in order activity from our customers pulling through our inventory, along with, as I said, the offset in builds for large customer ramps. They're happening somewhat simultaneously, not perfectly sequentially.
Vivek Arya (Managing Director and Senior Research Analyst)
Understood. For my second question, you mentioned content gains at your top two customers. Are these competitive wins or is this new TAM? Is your gain somebody else's loss of content or is it just new capabilities that the customers are planning to add? Kind of related to that, just given the nature of these customers, do you expect to retain this content in the following years? Are these multi-year programs or the visibility is only there for the first year? Thank you.
Bob Bruggeworth (President and CEO)
Yeah, thanks, Vivek. Part of the questions we can't answer, but I will tell you that it is both content and share gains at our largest customers, our largest two customers.
Vivek Arya (Managing Director and Senior Research Analyst)
Which can continue, Bob. These are like multi-year decisions or?
Bob Bruggeworth (President and CEO)
Can be, and some are, some aren't. We'll see.
Vivek Arya (Managing Director and Senior Research Analyst)
Understood. Okay. Thank you.

Our next question is from Blayne Curtis with Barclays. Please proceed with your question.
Blayne Curtis (Managing Director of Semiconductor and Semiconductor Capital Equipment Research)
Questions. Maybe I just wanna start, you've been kind of giving how large your largest customer or 10% customers are. Just trying to get a starting point for some of these moving pieces in December.
Grant Brown (CFO)
Sure. Our largest customer is a significant portion of ACG revenues, usually representing about 2/3 of that business, if not more in certain periods. Our second-largest customer, we haven't commented on, but it generally hovers around that 10% mark. You know, certainly with some of the growth we expect there, could be more.
Blayne Curtis (Managing Director of Semiconductor and Semiconductor Capital Equipment Research)
Gotcha. And then I guess following up on Vivek's question, just to try to gauge the magnitude of these content wins you're speaking to. You talked about being able to double capacity at Richardson. I'm assuming you have, given the pullback in Android, some excess capacity already. I'm just kind of curious the timeframe in terms of doubling that capacity, if you have that on your horizon.
Grant Brown (CFO)
Sure. Let me talk to that. I think just at the highest level, there isn't a BAW placement that we can't fully support at any customer at our Richardson facility, is really the key takeaway there. You know, we've driven some significant gains for the reasons I mentioned earlier in the prepared remarks. The productivity gains, the overall die shrinks, the move from 6 in to 8 in, and then of course, the successive generations of BAW filters that we're running through that factory lend themselves to a significant increase in capacity. You know, as we look at Farmers Branch, the need for that I guess over time has been somewhat of a safety valve in case any of those initiatives didn't come to fruition.
Given the success of the team there, we're able to support all the BAW based processing we need out of our Richardson facility.
Blayne Curtis (Managing Director of Semiconductor and Semiconductor Capital Equipment Research)
Okay, thanks.
Operator (participant)
Our next question is from Matt Ramsay with Cowen. Please proceed with your question.
Matt Ramsay (Managing Director and Senior Equity Research Analyst)
Thank you. Good afternoon, guys. I guess I was gonna ask two, and I'll swap the order because it kind of builds on Blayne's last question. In the BAW filter space, any changes in the competitive landscape there? I think one of your U.S. competitors has made a decent amount of progress on their BAW roadmap internally in the last couple of years, and it seems like some products might be a little bit closer To impacting sort of the market. It sounds like you're rarely confident in what comes in content gains to the last couple of answers that you've given. Any competitive dynamic changes with your primary competitors on BAW?
Grant Brown (CFO)
Yeah, no, no changes to our primary competitors. You know, to the earlier follow on regarding the capacity at Richardson, you know, that is something that we can do over time, not necessarily this year, but that's something that we have the ability to do in subsequent years to add on to the effective capacity there at Richardson. Again, just wanna make sure that's clear that we do have to take steps, add equipment, et cetera, in order to make that possible. It'll be in the out years, but it's really a comment around Farmers Branch and supporting the ability for us to do that in the future, given our ability to sell the Farmers Branch facility.
Matt Ramsay (Managing Director and Senior Equity Research Analyst)
Got it. Thanks for the clarification there. As my follow-up there, obviously, given how big it is in the revenue, most of the focus of the call here has been on the mobile and smartphone markets. I wanna ask quickly on the wireless infrastructure side, there's some, I don't know if they're correlated, but similar inventory dynamics that are happening. If you guys have any commentary about the inventory build up there, how has it come down? What timing of any potential re-acceleration? Is it similar to on the mobile side or longer, shorter? Just any context there would be helpful. Thank you.
Dave Fullwood (SVP of Sales and Marketing)
Yeah. I think that's pretty well known. We've seen inventory build up there, that's certainly been impactful to our infrastructure business. It'll take some time, we think, for that to bleed off throughout the year. It's probably similar, but maybe even take longer than what we'll see in mobile.
Matt Ramsay (Managing Director and Senior Equity Research Analyst)
All right. Thanks a lot. Appreciate it.
Operator (participant)
Thank you. Our next question is from Raji Gill with Needham & Company. Please proceed with your question.
Raji Gill (Managing Director of Semiconductors and Automotive Technology Research)
Yes, thanks for taking my questions. I just wanted to break down the commentary about September and December and March, if I could. Just, you know, the commentary about significant sequential growth in September off the flat June. What's driving that commentary is seasonally September is higher. Can you maybe frame it in terms of relative seasonal patterns? Is this also being aided by more of a significant rebuild and by these customers, plus share gains? Just any commentary around qualitatively what's specifically driving the September commentary. December and March being up year-over-year. Obviously December and March of December of 2022 and March of 2023 are relatively easy compares in terms of the revenue.
Just, kind of thoughts around December and March would be helpful. Thank you.
Grant Brown (CFO)
Yeah, sure. As we look into September, again, I would just reiterate, we're not providing any official guidance into fiscal 2024, but we're attempting to shape it just a bit given some of the macroeconomic uncertainty. Obviously, the macroeconomic situation will inevitably dictate the trajectory of revenue. Just looking at some of the drivers that we see seasonally, there is a significant ramp in the September quarter. As Bob stated, we feel as though we are well represented on large platforms across all of our largest customers. Continued strength at some of those customers as the channel inventories begin clearing will occur as well as a large seasonal ramp gets to a sequential increase in September.
That's pretty substantial off of a rather low base as we're talking about a roughly flattish June. That's the primary driver or caller around September. Then into December and March, you're right, the comps get relatively easy. With the channel inventory picture clearing up by the end of the calendar year, as we talked about earlier, it should provide for a restocking, if you will, or us selling into potentially demand even at just recurring to normalized levels.
Raji Gill (Managing Director of Semiconductors and Automotive Technology Research)
Got it. For my follow-up, regarding your conversations with the Chinese OEMs and the Korean OEMs, what is the kind of expectation as it stands today in terms of their customer forecast for calendar 2023 going into calendar 2024? Obviously, calendar 2022 was a kind of a horrific year in terms of units. Are the forecasts, you know, relatively conservative off that, you know, very challenging 2022? Are some OEMs more aggressive in their forecast plans? There's more capacity coming online for a variety of different smartphone components, does that enable new product ramps? Just any commentary in terms of what the customer feedback is and forecast. Thank you.
Grant Brown (CFO)
Dave, would you like to take that?
Dave Fullwood (SVP of Sales and Marketing)
Yeah, sure. The customer sentiment and their forecast is very cautious. I think, you know, we've seen some early signs of life in China in the smartphone sell through. First few weeks of January look promising, but we need to see a couple of months of that, and I think our customers do as well, before they really start to gain confidence there. Right now, their purchase order patterns, their forecasts remain very cautious at the outlook to the rest of the calendar year.
Grant Brown (CFO)
Does that answer your question?
Raji Gill (Managing Director of Semiconductors and Automotive Technology Research)
Oh, yes, it does. Thank you. Appreciate it.
Operator (participant)
Our next question is from Chris Caso with Credit Suisse. Please proceed with your question.
Chris Caso (Managing Director and Senior US Semiconductor Analyst)
Yes, thank you. The question is regarding CapEx and cash flow and, you know, both on a shorter term standpoint on how you plan to manage that as we still burning off inventory here. Then a bit longer term and, you know, kind of we're hearing from you is that it sounds like from a capacity standpoint, yeah, you may be set for a little bit. What can we expect there? Can we expect that, you know, that as the market normalizes and this inventory burns off and has some benefits to revenue that we see that flow through for cash flow performance?
Grant Brown (CFO)
Sure. We don't guide specifically to the balance sheet or cash flow, but I'll try to give a little bit of color on the drivers. You know, having now collected on sales in prior quarters, our cash flow will likely start to follow the path of the P&L, obviously. You know, as we look forward, we still expect to generate free cash flow, and CapEx should be in the 5%-7% range of sales, representing discipline there and some reduced CapEx intensity as we move forward, having invested in our facilities over the prior years. Looking forward will be largely capacity-driven, as we see demand and obviously improvements in our performance and technology required.
Generally speaking, I'm, you know, you know, be looking for the cash flow to follow P&L.
Chris Caso (Managing Director and Senior US Semiconductor Analyst)
Got it. Okay, just to follow on, and again, a lot of discussion has been on the cellular portion. You know, for the non-handset part of the business, I guess what I heard is some of the infrastructure products that there's still some inventory to burn off. What would you say more generally, you know, would be the inventory situation for the non-handset part of the business? Is this a situation where, you know, this is a little bit slower to come back as compared to the cellular business? What's the view of those businesses as you proceed through the year?
Grant Brown (CFO)
Yeah. It definitely varies. The, you know, the infrastructure business is probably gonna be slower to recover. You know, we've got, you know, Wi-Fi, a lot of that's consumer-facing, that'll be probably very similar to what we see in the smartphone space, but some of that's also more operator and enterprise-driven. We saw that occur a little bit later, that'll probably take a little bit longer to recover. Our power management business as well is very consumer-facing with power tools and solid-state drives and other types of devices like that that are more consumer-oriented. They'll, they'll go probably very similar to the way the smartphone market goes.
Chris Caso (Managing Director and Senior US Semiconductor Analyst)
Okay. Thank you.

Thank you. Our next question is from Harsh Kumar with Piper Sandler. Please proceed with your question.
Harsh Kumar (Managing Director and Senior Research Analyst)
Hey, guys. I wanted to ask about an earlier question that was asked about December growth and March growth. I know you said year-over-year, or the question was asked in reference to year-over-year, did you mean to say that, or is it possible that those businesses, given the falloff in revenues and units, is it possible that your businesses could also grow sequentially in this timeframe, or will they follow a seasonal pattern?
Grant Brown (CFO)
Are you referring to our fiscal 2024 or our just announced December and this March, Harsh?
Harsh Kumar (Managing Director and Senior Research Analyst)
No, no, fiscal 2024.
Grant Brown (CFO)
Fiscal 2024. It's a little early to comment on that. Certainly from a year-over-year standpoint, the comps are relatively easy, and it's with a high degree of confidence we believe we'll be able to grow. The degree to which would determine whether it was sequential or not, I think it's a bit premature to comment on. Overall, we still are encouraged by fiscal 2024 and believe that it'll be above fiscal 2023.
Harsh Kumar (Managing Director and Senior Research Analyst)
That's fair. I wanted to ask about your gross margins. Your revenues came down for the guidance for March, your margins are kinda hanging in there. You mentioned a couple of things, small things, the 80 basis points and 30 basis points issues. What's the reason why your margins are able to hang in here?
Grant Brown (CFO)
I think generally speaking, if I look back over the productivity gains that we've made over multiple years, we're still seeing those in our margins today, even though the volumes aren't in the factories. You know, 900+ basis points of headwind from underutilization is significant. I don't wanna understate that. But in terms of productivity and the work that our operational teams have done, is really speaking to the strength of those gains and our ability to hold margins at 40%.
Harsh Kumar (Managing Director and Senior Research Analyst)
Fair enough, guys. That's it for me. Thank you.
Bob Bruggeworth (President and CEO)
Thanks, Harsh.

Thank you. Our next question is from Joseph Moore with Morgan Stanley. Please proceed with your question.
Joseph Moore (Managing Director and Semiconductor Industry Analyst)
Great. Thank you. You talked about the changes to your foundry agreements. Can you just speak generally to the cost of foundry wafers? Do you see that continuing to rise? You know, and if so, are you able to pass that through to your customers? If it reverses, do you anticipate having to pass declines onto your customers? Thank you.
Bob Bruggeworth (President and CEO)
Thanks, Joe. actually, with some of the capacity freeing up, we're not seeing the increases that I know, we saw some of that, earlier last year. Last calendar year, earlier in the year. We're not seeing it. In some cases, to your point, we have been able to pass that on to our customers. Again, as we've always said, pricing is set by the competition. If we all raise prices, we all get an increase. If we all don't, we don't get an increase. We've been able to pass some of that along. As Grant pointed out, you know, the inflation is impacting us in our COGS about 80 basis points, we're not able to pass it all along. There's other inflation in there, not just, you know, foundry parts.
Harsh Kumar (Managing Director and Senior Research Analyst)
Got it. Thank you very much.
Bob Bruggeworth (President and CEO)

Thank you. Our next question is from Atif Malik with Citi. Please proceed with your question.
Atif Malik (Managing Director and Lead Analyst of US Semiconductors, Semiconductor Capital Equipment and Hardware Equipment)
Hi. Thank you for taking my question. I have one clarification and one question. When you guys talk about channel inventories to normalize later this calendar year, are you talking about China Android or total Android or total smartphone?
Dave Fullwood (SVP of Sales and Marketing)
We're talking about total smartphone inventories, even some of the other markets that we mentioned earlier in one of the previous questions. Again, we see elevated inventories, not just in smartphones. We see it in a lot of the other markets as well.
Atif Malik (Managing Director and Lead Analyst of US Semiconductors, Semiconductor Capital Equipment and Hardware Equipment)
When are you expecting, China Android, inventories to normalize?
Dave Fullwood (SVP of Sales and Marketing)
All depends on how well the phones sell through in the end market. Like I said, January, you know, early indications in January are it's improving. If that continues through February and March and into calendar Q2, then of course our inventory is gonna be burned off much more quickly. We're not forecasting that. We wanna see that sustained before we get too excited about that.
Atif Malik (Managing Director and Lead Analyst of US Semiconductors, Semiconductor Capital Equipment and Hardware Equipment)
Understood. Is it possible to break out or comment on how big the silicon carbide power device business is as a percentage of HPA sales?
Bob Bruggeworth (President and CEO)
Yeah, we haven't given that information. What I can tell you is we're very pleased with the acquisition. I know when we file our Q, you'll see why I say that. It's been a tremendous acquisition, but I'm sorry we haven't sized it. It's probably bigger than what most people think and smaller than what some other people think. We haven't given any of that revenue out yet, but we're very pleased with it. It's profitable and it's doing a fine job.
Atif Malik (Managing Director and Lead Analyst of US Semiconductors, Semiconductor Capital Equipment and Hardware Equipment)
Thanks, Bob.

Our next question is from Ambrish Srivastava with BMO Capital Markets. Please proceed with your question.
Ambrish Srivastava (Senior Equity Research Analyst)
Hi. Thank you. I just had one question, Grant. thanks for providing that, down 20%, comment. I'm just struggling with how does it help us. I ask with reference to what are we talking about? Are we talking days, months? What is normal level? I know it's harder in the more diversified areas, but in the handset side, you should be able to kind of quantify and tell us, all right, at the peak it was X weeks, X months, and here we are, and then we think if there's some kind of normal pattern, this is what normal level looks like.
Bob Bruggeworth (President and CEO)
Yeah, I think that's a great question, Ambrish. The issue always is when you look at your days of inventory in the channel, you have to understand what's the sell out. So far, and I think I said this last quarter as well, when we work with our customers, when we go through all the math, they re-reduce their production, we reduce ours, and unfortunately their sell out has been lower. You know, you have to look at it. Now, again, Dave's mentioned a couple times on the call, the first three weeks so far in January, at least, at least we can speak to the data that we get and I think all of you get, you know, the actual sell out is up, and that's a good sign.
We're not gonna get into the game of naming numbers like this because it all depends on the future output of what they sell out. We've got a little ways to go. That's why I think we're being careful on our comments around June, but we feel very good about September. We roughly think it's in that timeframe.
Ambrish Srivastava (Senior Equity Research Analyst)
Handset inventory cleaned out by September and the rest, as you said, others will take longer. Your best guess at this point is by December that should clean out as well, right?
Bob Bruggeworth (President and CEO)
Well, we've got different parts of the business. You know, in the Wi-Fi area it's gonna follow 'cause we're in a lot of the Android phones with our Wi-Fi products. It will follow more of what I said for the handsets. Wi-Fi that's in some of the retail and some of the industrial applications, things like that may take a little bit longer. We don't always get a good read there. It's a smaller part of our market, not as much data is published. I think on the infrastructure side, what Dave talked about, that is gonna take a little bit longer. The area of our power management that goes into the SSDs and, you know, that's a call on the PC market. You know, you guys follow that. We'll see how that goes. It's gonna be all different ones.
The major part of our business is the handsets, as you know, and I think we're giving you as much color as we can as we project forward.
Ambrish Srivastava (Senior Equity Research Analyst)
Yep. Got it. Appreciate it. Thank you, guys.
Bob Bruggeworth (President and CEO)
