Good afternoon, ladies and gentlemen, and welcome to the Q2 2020 Teradyne Incorporated earnings conference call. At this time, all participants are in listen only mode. Later, we will conduct a question and answer session, and instructions will follow at that time. If anyone should require assistance during the conference, please press star then zero on your touch tone telephone. As a reminder, this conference is being recorded. I would now like to turn the conference over to our host, Andy Blanchard, Vice President of Investor Relations. Please go ahead.
Thank you, Vincent. Good morning, everyone, welcome to our discussion of Teradyne's most recent financial results. I'm joined this morning by our CEO, Mark Jagiela, and CFO, Sanjay Mehta. Following our opening remarks, we'll provide details of our performance for 2020 second quarter, along with our outlook for the third quarter of 2020. The press release containing our second quarter results was issued last evening. We're providing slides on the investor page of the website that may be helpful to you in following the discussion. Replays of this call will be available via the same page after the call ends. The matters that we discuss today will include forward-looking statements that involve risk factors that could cause Teradyne's results to differ materially from management's current expectations. We encourage you to review the safe harbor statement contained in the earnings release, as well as our most recent SEC filings.
Those forward-looking statements are made as of today, and we take no obligation to update them as a result of developments occurring after this call. During today's call, we'll make reference to non-GAAP financial measures. We've posted additional information concerning these non-GAAP financial measures, including reconciliation to the most directly comparable GAAP financial measure where available on the investor page of the website. Please take special note of the safe harbor statement in the press release and slide deck for risks related to the COVID-19 pandemic and changes to U.S. export regulations. Looking ahead, between now and our next earnings call, Teradyne expects to participate in technology or industrial-focused investor conferences hosted by KeyBank, Citibank, and Deutsche Bank. Let's get on with the rest of the agenda.
First, Mark will comment on our recent results and the market conditions, including comments on the COVID-19 pandemic and expanded trade regulations. Sanjay will then offer more details on our quarterly results, along with our guidance for the third quarter. We'll then answer your questions, and this call is scheduled for one hour. Mark?
Good morning, everyone. Today, I'll summarize our results for the second quarter and the first half of 2020, comment on the impact of current environmental conditions, including new trade regulations, and then describe our view of the second half of the year. Sanjay will provide the financial details on the quarter and our guidance for Q3. Despite the pandemic, trade issues, and shutdown-related headwinds in industrial automation, Teradyne is performing exceptionally well. Our second quarter results affirm the trend of growing test intensity and the efficiency of our business model. As you can see from our Q3 guidance, the market demand remains robust. While Q2 saw record SOC shipments, 3Q is being driven by growth in memory test and system-level test. Industrial automation continues to pull out of the effects of global industrial shutdowns, as we saw sequential monthly growth in sales throughout second quarter.
We expect second quarter to be the bottom for IA and 3Q sales to be back close to 2019 levels. Superb execution by the global Teradyne team was on full display in second quarter as we managed to deliver new shipment records and tests. Supply line constraints were largely mitigated and remote technical collaboration both within Teradyne and with our customers continues to show success. It takes dozens to hundreds of engineers working in concert to develop new test products. It takes similar numbers working with customers to launch test programs for new silicon. Flipping a switch to do this remotely without missing a beat is a fantastic accomplishment, and I congratulate and thank all the employees at Teradyne for this achievement. On the trade front, new regulations related to both Huawei and China military end users were announced in the second quarter.
We expect the China military end user restrictions to increase our compliance work and costs, but we currently do not expect any material impact on our sales into China. In the case of Huawei, while the new regulations do not impose any new restrictions on our business with Huawei directly, we expect it will likely impact our business with subcon customers who test Huawei devices using our test equipment. We expect the macro global test demand to be minimally impacted as alternative sources of silicon supply grow to fill in whatever gap is created by these regulations. This alternative supply should absorb any idled test capacity as well as drive new demand in the future.
Shifting to the highlights, as we reach the midpoint of the year, our January forecast for a $3.1 billion-$3.4 billion SOC test market is playing out about as planned, while our memory test market estimate has moved up to about $800 million-$850 million. In SOC, our sales grew 60% in the first half and 82% compared to 2Q of 2019, as our participation in this year's mobility tooling cycle is significantly stronger than in the last two years. As expected, 5G infrastructure-related capacity add remains weak after a strong 2019, while handset-related silicon is driving the bulk of the demand.
While 5G-related silicon is beginning to add a small piece to the mobility handset market, the vast majority of the test demand is complexity growth in non-5G related handset silicon. Whether related to high-resolution still or video photography, artificial intelligence, augmented reality, gaming, location sensing, or advanced wireless connectivity, there is a rich set of features in addition to 5G that we expect will continue to drive mobility demand for the foreseeable future. Specific to 5G, we are still in the early innings of a multi-year rollout and expect it to be an incremental demand driver going forward. Additionally, our new UltraFLEXplus platform will continue ramping in 3 Q, providing new revenue sources in mobility and computing going forward. Beyond mobility, the automotive and industrial segments of the SoC test market remain weak, and we do not expect to see recovery until 2021.
In memory, our 2Q sales were about flat with Q1, but up 45% from Q2 of 2019. Flash package test and DRAM wafer test, combined with ramping shipments of LPDDR5 package testers, drove Q2 results. DRAM test is growing faster than flash test in 2020 due to the LPDDR5 transition, and our design win in DRAM should allow us to hold our share position in the low 40s this year. In the system test group, sales were up 43% for the first half compared to 2019 due to strong storage test demand. We expect storage test shipments to grow sequentially and substantially in Q3, driven by both HDD demand and semiconductor system-level test shipments. System-level test is a great example of derivative products opening new markets for Teradyne.
By combining silicon test instruments with our HDD test product, we've grown the combined sales from $60 million in 2017 to over $200 million this year. At LitePoint, sales were up 32% for the first half and 19% compared with 2Q of 2019. Demand is being driven by Wi-Fi 6 and growing shipments of 5G test sets. Wi-Fi 6 has recently been allocated additional frequency spectrum in the 6 to 7 gigahertz range. Testing this expanded standard, called Wi-Fi 6E, will require new testers, which we expect will be a positive force in 2021 and beyond. Moving to industrial automation, the environment is mixed, improving. At UR, the biggest unit of our IA segment, sales in Q2 contracted 32% compared with the same period last year. Manufacturing shutdowns in Europe and North America had a significant impact on UR.
MiR sales, on the other hand, grew 7% from last year's Q2 level as they benefited from exposure to healthcare and mobile disinfectant markets. AutoGuide, our newest IA business, saw sales more than double from the same 2Q period last year. Overall, IA sales for the first half were down 15% from 2019. We have seen positive indications of improvement as we move through second quarter. For example, all three businesses had sequential monthly sales growth across Q2 as customers began to reopen. While we expect IA demand will improve in the third quarter, we don't expect to return to year-on-year growth until Q4 or Q1. Our longer-term growth outlook for IA remains unchanged at 20%-35%. Social distancing and the need for more resilient manufacturing flow should add additional drivers for our collaborative automation products.
Our R&D and distribution investments in the IA business continue as these macro-driven slowdowns provide opportunities to widen our competitive lead. We continued to add distributors in the second quarter, expanded our UR+ stable of certified plug-and-play products to over 250 items. We also introduced UR+ applications, moving to complete solutions for specific customer requirements like industrial bin picking and welding. Stepping back to look at the full year at the company level, our latest estimates have revenue front half loaded at about 54%-55%. This is similar to what we experienced in 2016 and 2017 when we saw especially strong investments for smartphone test capacity. In summary, the first half of the year showed Teradyne strength in familiar test markets and demonstrated our ability to grow in new ones with differentiated products and exemplary execution.
Our business model is efficient and driving the planned drop through on incremental sales. Our investments to broaden our competitive moats in IA amidst a global industrial downturn show the value of Teradyne's financial strength in these nascent industrial automation markets. While our short-term visibility remains limited, we are confident that our long-term strategy will continue to deliver outstanding results for our customers, employees, and investors. I'll turn things over to Sanjay for additional color and the financial details.
Thank you, Mark. Good morning, everyone. This morning, I'll review how the pandemic is impacting us from a financial and supply line management perspective. I will then summarize our Q2 financial results and Q3 outlook. Our priorities remain consistent during the coronavirus pandemic: safety of our employees, supporting our customers, and crisp execution to achieve our financial objectives. In line with my Q1 earnings call remarks, I want to acknowledge the continued challenges our employees, customers, suppliers, and their families going through during this pandemic. From a financial point of view, Teradyne is stronger than ever. We generated $178 million of free cash flow in Q2 and ended the quarter with approximately $1.1 billion in cash and marketable securities, and no short-term debt. During the quarter, we established a $400 million revolving line of credit for added security against future uncertainty and opportunities.
The strength of our balance sheet, business model, and business execution enabled us to put the revolver in place during a very uncertain time. Our long-term debt is a $460 million face value convert, which matures in December of 2023. From an operations perspective, our team and partners have done a great job so far this year. Over many years, Teradyne has built a global supply line management team second to none, and the value of that team has never been more evident. COVID-related supply line issues did not have a material impact on our revenues in Q2. Our combined teams produced the highest number of UltraFLEX systems ever in the second quarter, ramped new products in SOC, memory, and across our IA businesses, all while operating in a very challenging environment. This included overcoming numerous part and labor shortages along with logistical constraints.
In one case, a shortage of scheduled air cargo capacity led us to charter a dedicated 747 to deliver, quite literally, a planeload of testers to a customer to ensure timely delivery. While operationally executing very well, we continue to take a critical view of how to strengthen our supply chain operations. We have identified potential weaknesses and are taking actions to strengthen our operations further. The short-term COVID-19 related actions, along with these long-term actions, have a small impact on margins. While the operations team clearly shined in the quarter, they were not alone. I'd also like to extend thanks to the entire organization, from HR to facilities and environmental health, to engineering, repair services, finance, legal.
Our global field and applications teams, which collectively allowed us to meet our delivery commitments, add a revolver, introduce new products, maintain our R&D programs, and run the company safely and productively with a combination of at-home and on-site staffing. Well done. Very well done. On to the details of the quarter. Revenue in Q2 was $839 million, up 49% from Q2 of 2019 and up 46% for the first half of the year. Q2 revenue was 5% above the high end of the range, driven by accelerated shipments and SOC test. While IA contracted year-over-year, IA revenue was higher than expected in Q2. Semi test revenue was $659 million, up 76% from a year ago, driven by, one, SOC revenue was $575 million, up 82% from a year ago on broad strength and mobility.
Two, memory revenue of $85 million, up 45% from a year ago due to continued strength in flash test and ramp-up of our Magnum FX solution for DRAM. In system test, revenues were $72 million, which included storage test shipments of $36 million, which were down sequentially, but up 6% from Q2 of 2019. Recall our storage test business tends to have lumpy shipments. First half storage test revenue was up 106% over the first half of 2019 on strength in both system-level test and HDD product lines. Growth in SLT was driven primarily by processor demand, while HDD shipments were driven by strong exabyte growth for hard drives. LitePoint revenue was $49 million in the quarter, up 19% from Q2 of 2019 on 5G, Wi-Fi 6, and next-generation Wi-Fi 6E demand.
In Industrial Automation, revenue was $59 million, down 21% from Q2 of 2019 due to the coronavirus and down 3% from Q1 2020, but above our plan entering the quarter. UR contributed $43 million of revenue, MiR $11 million. AG and Energid made up the remainder. We believe in our IA segment, revenue bottomed out in Q2 and is on the road to sequential growth in Q3. We had one 10% customer in the quarter. As a reminder, we disclose customers who contribute 10% or more of full-year company revenue in our annual 10-K. Non-GAAP gross margins in the quarter were 56.2%, down 130 basis points from Q2 of 2019 as forecasted. Margins reflect the impact of concentrated mobility shipments in Semi Test and the added logistics and operations costs due to the pandemic.
Non-GAAP operating expenses were up $11 million to $207 million from Q1 due to company performance causing higher variable compensation. Inventory increased to $206 million to support Q3 shipments and buffer against potential COVID-19-related supply disruptions. DSO in the quarter increased to 75 days due to the timing of shipments in the quarter. Non-GAAP operating margin was 31.5%, and non-GAAP EPS was $1.33. Both are tracking ahead of our 2022 model. Tax rate in Q2 of 2020 was 13% on a GAAP basis and 14.1% on a non-GAAP basis. Our full-year GAAP tax rate is expected to be 14%, down from our prior estimate of 14.5%. Our full-year non-GAAP tax rate is expected to be 14.5%, down from our prior estimate of 15%. The decrease in tax rate is due to product mix. We generated $178 million in free cash flow in Q2.
We paid $17 million in dividends in the quarter. We bought back 173,000 shares for $9.4 million at an average price of $54.49 in the first few days of the quarter. As noted in April, we suspended our share repurchase program as of April 1st. We look at our share repurchase and the entire capital allocation program regularly, and we'll update you next quarter. Looking ahead at Q3, revenues will include a significant ramp in shipments of our new UltraFLEXplus SOC test system supporting recent design wins. In memory, we expect continued strong momentum for our Magnum product line for flash and DRAM applications. LPDDR5 test shipments are expected to grow significantly in Q3. In our system test group, storage test demand driven by system-level test and hard disk drive markets continue to see end market demand exceeding our expectations for the year.
While this business fluctuates from quarter-to-quarter, Q3 is expected to more than double the Q2 level. I'll also note that while we expect multiple waves of 5G-related demand for both handsets and infrastructure in the years ahead, we are not planning on significant infrastructure test shipments in the second half like we experienced in 2019. As a result, we expect to revert back to pre-2019 pattern of lower Q4 SOC shipments. In industrial automation, we are seeing incremental improvements in UR's business. As the U.S. and Europe start to open up, we are seeing signs of increased momentum in quarter-over-quarter. Recall the U.S. and Europe typically represent greater than 70% of UR's revenue. UR continues to execute, and in the first half of the year grew by 4% year-over-year, driven by ultraviolet light disinfectant demand.
In Q3, we are guiding a revenue range of $745 million-$805 million, and a non-GAAP EPS of $1.01-$1.17 on 175 million diluted shares. The ranges reflect continued COVID-19 supply risks and potential impact on end market demand. The guidance excludes the amortization of acquired intangibles and non-cash imputed interest on convertible debt. In April, we previewed expected gross margin headwinds in the second half of 2020 due to new product ramps. While the ramps continue as planned, our latest view is the impact will be less severe than earlier expected. Q3 gross margins will be 55%-56%. We expect to be back to historical gross margin levels in 2021. In Q3, operating expenses are expected to be 26%-28% of sales and are on track with our revised April full-year plan to grow 7%-8% from 2019.
The operating profit at the midpoint of our third quarter guidance is 29%. CapEx investments year to date are $84 million, and we expect full year investments will total approximately $175 million. We're investing more in CapEx this year to support new product rollouts, strengthening our supply chain, and new facility projects. To summarize, we close out Q2 with outstanding financial and operational performance in a difficult working environment. We enter Q3 with a bright outlook on the strength of new product ramps and an industrial automation market that is showing signs of early improvement. While our visibility is limited and we're not immune to macroeconomic shocks, I'm confident that we have the products, people, and processes to thrive in the quarters ahead. With that, I'll turn things back to Andy.
Thanks, Sanjay. Vincent, we'd now like to take some questions, and as a reminder, please limit yourself to one question and a follow-up.
Ladies and gentlemen, if you have a question at this time, please press star, then the number 1 key on your touchtone telephone. If your question has been answered or you wish to remove yourself from the queue, please press the pound key. Our first question comes from the line of Mehdi Hosseini from Susquehanna. Your line is now open. Please ask your question.
Yes. Thank you for taking my question. Two question. First, I want to better understand how to think about the earning power. I think it was two quarters ago that you highlighted a $3.5-$4.25 earning by 2022, and your recent execution suggests that you're already at that run rate. My question to you is, given the share gains in memory and other areas, do you think there is an upside to the earning scenario that you laid out six months ago? Perhaps a $4 earning is sustainable, and it shouldn't be viewed as a one-time event? My follow-up question has to do with China. How much of a revenue contribution did China provide? Thank you.
Hi, it's Sanjay here. I think this year we'll come close or be in the range of hitting our earnings model out in 2022, on the top line and the bottom line. Obviously, there's many puts and takes relative to what we published in the earnings model, specifically strength in semi test and storage business offsetting the near term impacts of COVID in the IA portfolio. What we'll plan on doing is in January, updating that earnings model and provide guidance for the future then.
I think just I'll add, Mehdi, that as you know very well, we have a very volatile market that we play in. To sustain linear growth throughout a decade is not the kind of business we're in. The trend lines, we do believe, support certainly reaching and exceeding that midterm earnings model. That in no way is going to be a peak for Teradyne.
Great. Congrats. Just quickly on China, what's the revenue contribution of China?
In the quarter, China was about 12 and a half% of revenue.
Okay. Thank you.
Next question comes from the line of Vivek Arya from Bank of America. Your line is now open. Please ask your question.
Thank you for taking my question, congratulations on the strong results and the execution. Mark, you have brought up the test intensity factor a few times, we honestly do not know how to put that in our model. When I look at your SoC test business, it's up, I think on track for over 30% growth, overall phone volumes are down according to TSMC in mid-teens, even though the 5G part has been relatively strong. How do you quantify this test intensity factor per unit? Is there a 5G versus 4G comparison? Importantly, how will this test intensity factor evolve as you go into 2021? Will it be 5% better or 10% better? How do we size that? Without knowing that, it's very difficult to size what your SoC sales will do going forward.
Yeah, I appreciate the difficulty because if we had a formula, believe me, we would be using it and advertising it. I do think what we've said is when we look at the big picture, we see that the growth in transistors is what drives complexity, and that over an average trend line gives us test growth, market growth in that 6%-8% range. There's many puts and takes that go on every year. Depends if people are making a major transition from a node, like a seven to five nanometer node, that enables more transistors and typically has lower yields that come with it. It's very lumpy year to year and very hard to model year to year.
The net effects, when you look back historically for the past 5-7 years and at our projections, are that sort of 6%-8% trend line growth for test. I don't think anything's changing in that, but it's not going to be smooth. It's going to be lumpy. The other thing that affects this, if you look at this year, for example, the market for SOC test is really flat with last year. It's about a $3.1 billion-$3.4 billion market, and the underlying economic effects of what's going on in the world and cell phone unit declines and such as, and automotive being off and industrial being off, is netting out to a flat market. Teradyne, on the other hand, is obviously picking up a lot of market share this year. That's both good news and bad news.
I think the bad news is we'd love to see the market grow every year, but in a very difficult macro year like this, the fact that it's holding its own despite the weaknesses in the pockets I just mentioned, is encouraging. We expect as we come out of this pandemic and the global economy start growing again, those markets will continue to grow along those trend lines. I wish I had the formula, don't, but I think the evidence is sort of speaking for itself.
Got it. For my follow-up, Mark, when I look at again, on the business as it relates to 5G, can you give us a sense for how much of your business is infrastructure versus handsets? As part of that, let's say if 5G handsets 3x next year, what does that do to your SOC test business intensity being same or better? Does it mean your tester business will 3x, or give us some sense for how we kind of try and correlate the growth prospects to the number of 5G handsets and the demand for infrastructure. Thank you.
5G is a piece of a phone. The silicon related to 5G in a phone is one part of a phone, so there's no way that tripling a 5G triples our tester business. To give you some sense, the infrastructure piece of 5G was very robust last year, and we talked about it all year long, and you saw that our business level grew toward the back end of the year due to infrastructure investments. Then we talked about the fact that those investments would taper off in 2020, which they have, and what would come into the market would be handset-related growth. We're still talking about, and we've also said 5G in aggregate should add to our test business somewhere between $400 million-$500 million of market.
If Teradyne's at 50% of the market, that should add, let's say, $250 million to Teradyne's business when it's peaking. We're not peaking. We're not near peaking. This year, we're maybe $200 million into that $500 million envelope. That will give you the sort of calibration on how much you might think 5G could mean to us over the next 4-5 years on an annual basis. When we get to that mature $500 million level, hopefully we're running at that 250 ± additional revenue level. Thank you.
Next question comes from the line of Brian Chin from Stifel. Your line is now open. Please ask your question.
Hi, Mark and Sanjay. Great results, thanks for letting us ask a few questions. First, as was just discussed in the last question there are clearly company and industry-specific factors contributing to your 50%-60% year-over-year, year-to-date growth rate in semi test. Do you think a layer of this growth could reflect your customers or customers' customers attempt to put some inventory in place, be it wafer, chip, or even end device, to safeguard against future supply chain and demand uncertainties? I would appreciate any thoughts.
Yeah. Hi, it's Sanjay. We do a lot of work in trying to triangulate our shipments and trying to understand utilization and inventory levels of testers out there. I think what you saw in 2019, as Mark articulated earlier, was a buildup of infrastructure test tooling, and which kind of built a capacity so they could have a run rate. From an end market and inventory perspective, we're not seeing tester inventory build. We're always on the lookout for it and concerned about it. From the analysis we've done, we actually don't see that inventory buildup.
Okay, great. You're talking more about the equipment versus further downstream in terms of that activity?
Yeah, mainly from the tester equipment. It's very hard from an end market perspective, whether be it smartphone or industrial or automotive, to think about those inventories.
Sure. Okay. I was kind of gearing it more further downstream, but I appreciate the commentary. Maybe one last one. I know you're not guiding fourth quarter per se here, but based on your 54%, I think the 55% first half weighted revenue comment, does that roughly suggest 4Q sales would be down something like 30%-35% sequential? Would you expect semi-test sales to decline at a similar or higher, lower rate?
Yeah, we're effectively guiding down 35%-40% versus Q3 mid. Yeah.
Yeah, I think when you do the math, exactly what you just did. Now the decomposition of the various businesses in that, there's a lot still in flux. IA tends to be up in the fourth quarter, and we expect that will continue. I think last year was atypical with the strong semiconductors, so I think if you looked at prior years, you'd get essentially the same kind of mix.
Okay, great. Appreciate it.
Next question comes from the line of John Pitzer from Credit Suisse. Your line is now open. Please ask your question.
Yeah, good morning, guys. Congratulations on the solid results. Thanks for letting me ask the question. Mark, you said in your kind of prepared comments that as these next wave of Huawei bans come into effect, you don't see much of an impact to global test capacity as other suppliers fill the void. I'm just kind of curious, I know it's a little bit of a guessing game, but when you look at the potential suppliers to fill that void, how does your share with those suppliers look vis-à-vis Huawei? I guess importantly, do you think the test capacity that's out there just gets repurposed for these different suppliers, or do you think it might actually cause some incremental buying?
I think over the long haul, meaning let's say a year, I think they'll be repurposed, and there could be incremental buying early on. We're in a period right now where the testers are still very full up, being used through this September 15th date, until we get past the sort of grace period and into the embargo. Post that period of time, there could be some spot buying because they're not completely fungible, but over time, they'll work their way into the supply and demand balance. There's no long-term consequence here that we see. Our share position in the alternative sources of supply, some are better, some are a little lower. I think when we've analyzed it overall, I think we're neutral.
We don't see that we're going to be overly benefited or a detriment because of the shift in who's going to make the silicon for those products.
Mark, just going back to the implied guidance for the calendar fourth quarter, that kind of implied sequential decline is not without precedence in your business model. If I go back to like the 2012, 2013, 2014 period, you saw that kind of fall off in Q4. I'm just kind of curious, given how uncertain the environment is today, is that your attempt at a conservative placeholder, or do you actually have visibility out to the December quarter that informs kind of that view of a 55/45, half on half split?
Yeah. What I would say is that if even more recently, you looked at 2016 and 2017, one of the differences we're seeing right now is that those were also heavy tooling years for smartphones for us. We saw pretty significant drops from Q2 to Q3 in those years, maybe on the order of 20%-25%, followed by another 5%-7% in Q4. This year, instead of the two Q to three Q drop, we're kind of seeing it all come in Q4 is our forecast. Our visibility is actually quite limited out there. Obviously, when you look at what we've been doing this year, and if you've followed us a long time, there's quite a bit of variability in the out quarter in terms of what might materialize.
We don't have a lot of backlog that extends out that far and what will actually happen, there's quite a wide range around it. It's based on the modeling we can do, the customer conversations we're having, and those kind of things.
Helpful, guys. Thank you.
Next question comes from the line of Atif Malik from Citi. Line's now open. Please ask your question.
Yes, so thank you for taking my questions, and good job on the results and guide. Mark, can you talk about the timing of the millimeter wave opportunity, when you expect the infrastructure part of the investments to evolve, and also on the mobility side?
Millimeter wave, frankly, I think is quite a ways off from being a big part of the infrastructure and then subsequently handset story. None of the geographies are moving aggressively with millimeter wave. In the U.S., there's some boutique deployments, I would say, in urban areas and some high-density areas. What it appears most of the U.S. carriers are going to do is roll out sub-6 GHz in some flavor first, and then slowly move toward millimeter wave. Our view is, there certainly will be handsets at the premium tier that have that capability to run on those scarce networks, and there'll be some bump, and we've seen it already this year. Our millimeter wave shipments of test equipment at both LitePoint and SemiTest are tens and tens of millions of dollars.
It's not insignificant, even at the minuscule volumes we're talking about. It's probably not until 2022, 2023, before it starts to matter, would be my estimate.
Great. You talked about design wins in computing, which is a relatively new area for you guys with UltraFLEXplus. We've also heard that one of your customer's customer is moving to Arm-based CPUs for their notebooks, and those CPUs have much larger die size than the apps processor used in smartphones. How do you look at your computing share gain opportunity over the next 12 to 18 months?
Hi, it's Sanjay here. The compute market is roughly annually $500 million-$600 million, and our share has been roughly 30%, give or take, historically. Our new UltraFLEXplus product will help us grow that share, and this initial design win will help along that journey. That's how we're thinking about it in the near term.
Thank you.
Next question comes from the line of Toshiya Hari from Goldman Sachs. Your line is now open. Please ask your question.
Good morning. Thanks for taking the question and congrats on the strong results. Mark, I wanted to ask about your system test business, both on the HDD side as well as the SLT side. In terms of your HDD business, you've been speaking to this business and the strength there for a couple of quarters now. How are you thinking about sustainability of that strength into, I guess, Q4, since you're guiding up Q3? On the SLT side, your nearest competitor here, I guess, they've been pretty vocal about this specific application as well over the past couple of quarters. How are you sizing the opportunity in SLT, and how should we think about your competitive position relative to not just Advantest, but also some of the other players that play here? I have a follow-up. Thank you.
The whole storage test business, whether it's HDD or SLT, has been a tremendous story, and it's surprised us, and it seems as though the sustainability of it is pretty robust. It doesn't mean it's not volatile. Even in this year, you can see that quarter to quarter we can swing on shipments 20, 30% a quarter. It's quarter-to-quarter volatile, but the overall underlying demand is very strong for both HDD and SLT. The SLT side of it, as we described before, it's still somewhat of a nascent market. This is an additional test step that manufacturers of some high-volume digital-centric devices are using to further reduce defects per million.
The economics of this insertion are something that both customers and equipment suppliers like ourselves and others are working to try to make more attractive for other classes of devices, lower volume devices, more mixed signal with RF and analog content and such. The rate of adoption of SLT is just a big unknown in this. Even with the limited adoption that exists today, you can see that from last year when the early adoption occurred outside of compute, which it's been doing this for quite some time, it's grown to be pretty significant. It might be a $300 million tester market, something like that this year. We're probably splitting it roughly 50/50 or so with Advantest in just sort of the test area. I do think it's got legs.
I do think that the underlying complexity issues we're talking about compel these additional test steps in the very high end of complex devices. It's going to be a growth industry. It's going to be volatile, though. Until we get a dozen customers adopting this widely, you're likely to see these quarter-to-quarter and year-to-year fluctuations that we've seen up till now.
Thanks for that. As my follow-up, I wanted to ask about the industrial automation business and how you're thinking about the long-term growth profile there. I think in your prepared remarks, you reiterated your long-term growth target. Curious, just given COVID-19 and the potential impact it could have on how your customers and customers' customers think about their factory footprint, I guess. Could this drive a significant increase in adoption rates of things like UR cobots and MiR robots? Is it a little early to make that call? Thank you.
Yeah. Hi, it's Sanjay here. I think since 2015, we've experienced significant growth in UR, then adding MiR in 2018, and then as well as AutoGuide in 2019. That growth we expected to continue in 2020. Obviously, COVID hit, and we're looking at potentially a contraction year, depending on how the market shakes out in the second half. However, our belief is that we're going to continue, over the long run, to grow at the 20%-35% as Mark stated in his prepared remarks. Really, I think that, you consider over the short term, I think there's going to need to be a balance of getting people back to work versus industrial automation. However, in the business development activities, we're seeing a lot of activity in plant managers and decision-makers looking to harden their production lines and social distance.
We are seeing activity even in the short term. I think in the long term, it will provide a tailwind. However, we're still in the midterm around the 20%-35% growth, and we still continue to invest in product differentiation and application differentiation in those businesses.
Thank you.
Next question comes from the line of CJ Muse from Evercore. Your line's now open. Please ask your question.
Yeah, good morning. Thank you for taking the question. I guess first question, in your prepared remarks, I just want to double-check here. I think I heard you say that system test would double from $72 million in Q2 into Q3. Is that correct? As part of that, can you give us an idea of where we should be thinking about the growth balancing storage versus traditional system test?
Yeah. You're right. I did say that we would more than double in Q3, but it was off a baseline of $36 million in storage.
Storage.
Yeah, in storage.
Oh, that was just the storage comment, not overall system test.
Correct.
Okay. Great. Then, I guess as my follow-up question, thinking through the SOC market, it looks like your share is probably going from 40% to low 50s year-over-year. I guess, was hoping for you to parse through the drivers there. Obviously, mix plays a role, and you do have your largest customer turning on. They're also bringing on Arm-based processors, I believe embedded AI that really helps you guys. You have new UltraFLEXplus, and then you talked 5G being only a minimal driver. Amidst that backdrop, what are the key drivers of that share shift? More importantly, how should we think about the sustainability of that share looking into 2021?
You're right. We think probably our share in SoC moves up around 50% this year, and much of it, the majority of it, is due to the shift of who's buying. In the last couple of years, our share kind of came down. It wasn't customers defecting, it was who was buying. This year, the biggest piece of the 10-point or so share gain in SoC will be opposite effect of our customers are buying more. However, there's also this component. We've talked about the UltraFLEXplus and the design wins we've had in mobility and compute. Those are going to in the back half of the year add additional new revenue streams for us. We are picking up real customers, too, on this. That's not insignificant, and that won't completely mature in 2020. It's going to be more of the beginning.
That will grow throughout 2021 and 2022. We do have a lot of headroom to continue to move our share north of 50, based on those design wins, other ones in the pipeline. As you know, the underlying sort of core buying will fluctuate year to year. If you go back to 2016 and 2017, we had some very big years of tooling for our customers around smartphone silicon. 2018 and 2019 was a bit down. We picked up new business in infrastructure to sort of offset part of that. Now we come back, it's gangbusters. That could persist for a while, but it's going to still be volatile, I'm sure.
Riding on top of that is this little new wedge of new revenue streams in SOC based on real design wins, that gives us that ability to keep, on average, moving our share north. We've talked about long-term, getting to 60% share of this market is reasonable. Once you're past 60, they'll be a little bit more difficult, perhaps. 60 is certainly within a line of sight.
Great. Thank you.
Next question comes from the line of Timothy Arcuri from UBS. Line is now open. Please ask your question.
Hi, thanks. First of all, I wanted to get what the 5G portion of the SOC TAM is this year. Let's say you're saying three-one to three-four. I'm just wondering how much of that's 5G. I had another one. Thanks.
Yeah. We struggle to estimate that one precisely, but again, I'll just give you the context and give you my best guess for the numbers. We've said that at peak, 5G should represent about a $400 million adder to SOC test and about $100 million adder to LitePoint test. Of that SOC $400 million max envelope, this year, 5G is probably somewhere in the $200-ish million range for a TAM.
Got it. For wireless, Mark, how much of the wireless piece is coming?
Yeah. In wireless, of $100. We've actually seen that wireless may grow to be a bit bigger than 100 adder. It could be a 150 adder or so. This year, the wireless is probably in that, this is production test, not R&D test, but it's probably in that $60 million-$70 million range for the market.
Got it. Okay, awesome. I just wanted to follow up on the last question. There's a lot of stuff going on beyond your big customer and, certainly you have the UltraFLEXplus ramping. Usually, a significant portion, we'll say, of your share gain this year, you're going to gain 13, 14 points of share is because your big customer's having an on year. Usually, they don't have two straight on years. I'm just sort of wondering, if you strip away all the other stuff going on and you look at how sustainable that low 50 share is into next year, why would it be different this time where they would have two straight big on years versus history where they've had one on year and then they've had an off year? Thanks.
I think history is interesting in this. You look at 2016 and 2017, actually, our smartphone-related business was pretty flat and consistent and high. Those were peak years in the past, and it was two successive years. I think the on-off, on-off pattern goes back to the earlier part of the decade. I think 2016 and 2017 are equally valid thoughts and models around that. That's one thought. It doesn't necessarily mean up and down. At some point, it's not going to be what's norm and baseline, I think, is a judgment. I'd go back to that sort of trend line of the market. We expect to grow 6%-7%. If the SOC market this year is again, let's say $3.3 billion, nominally, we're talking about a market that should be $3.4 billion-$3.5 billion, everything else being equal next year.
I do think we can have two sequential strong years because we've had them in the past, and there's nothing wrong with that. We have these new design wins coming online that haven't matured yet. The thing we haven't talked about that's out there is memory. Memory is having a pretty strong year this year. If you look into 2021, the 2021 era is going to see this large shift from DDR4 to DDR5. This year, we're at the very early innings of the LPDDR5 shift for more mobile devices. The DDR5 shift is coming, and as we've said, that obsoletes the install base of DRAM test equipment for final test. There's a big retooling coming there as well.
Okay, thanks.
Next question comes from the line of Krish Sankar from Cowen and Company. Your line is now open. Please ask your question.
Yeah. Hi, thanks for taking my question. I had two of them. First one, Mark, to just follow up on your comments from the previous question. You said a couple of sequential growth years. It looks like you had, from a SOC Test market standpoint, you had five years of continuous growth. I'm kind of curious to understand the test intensity is going up and 5G seems to be a longer and a stronger cycle. Going forward, should a $3+ billion be a decent bogey to use for the SOC market side? I have a follow-up.
Let me just add a few more comments about where we are. You're right, we've seen the market show sequential annual growth and for quite some length of time here. This year, it's maybe going to be about flat, but it may show a 4% or 5% growth as well by the time the year is over. That's absent any real interesting participation of automotive and industrial buying. This is heavy mobility, and it's also in the midst of a pandemic, and it's also in the midst of all the regulations coming in around China. I'll go back and say, I would model in a 6%-8% TAM growth rate for SOC over the midterm, 4 to 5 years. That is what we should be tracking at.
Got it. That's helpful. Then as a follow-up, Mark, can you just tell us how much of your revenue was from LPDDR5? When I look at your memory market size, you're talking about $800 million-$850 million. Six months ago, it was more like $650 million-$750 million. Clearly, the upside is coming from DRAM. I'm just trying to figure out on the market size, how much of the upside is coming from LPDDR5, and within that, how much of your revenue is coming from LPDDR5?
Yeah, I'm not going to break out our LPDDR5 revenue, but I will say that the increase in the market size is both flash and DRAM. It's about 2/3 DRAM and 1/3 flash compared to our estimate in January. We are seeing upside on flash too. Much of the upside in DRAM is related to LPDDR5, so you would expect, and because our share is going to be flat, you can derive a close estimate of maybe how much revenue is coming out of that for us this year. We're working on design wins to hopefully capture more of the DRAM market. We just introduced that product in Q4 last year, and we're ramping it this year. That's what gives us upside going into next year, we think, around DDR5.
We talked in earlier calls about our sort of 40%-45% market share that we have. With the products we have today and the competitive position we have today, we should be able to move that into the low 50% range here in the next couple of years, if we really execute well. That's what we're focused on and planning.
Thanks a lot, Mark. Very helpful.
Next question comes from the line of Richard Eastman from Baird. Your line is now open. Please ask your question.
Yes. Good morning. Good morning, Mark, Sanjay. Very nice quarter to be sure. Just a couple of questions. I'm just going to focus for a second or two on the IA business. Could you talk about how the business progressed? You talked perhaps a little bit about some upside in the quarter here relative to your expectations, but could you talk maybe geographically what you're seeing in IA around Universal Robots and maybe just discuss any successes you might have? You talked about some self-help initiatives around distribution and around some new product applications coming to market. Maybe just provide a little bit of color on there because it seems like that business is at least stabilized, if not maybe getting back towards growth mode.
Yeah. Hi, it's Sanjay here. I'll talk a little bit about kind of the geo and kind of monthly profile. For UR, when I take a look at China, first to go into COVID and first to kind of come out, when we take a look at kind of the monthly profile, we saw improvement in March, then sequentially, we saw improvement throughout the quarter, really kind of coming back strong. When we take a look at, not back to last year's levels, but improving Q2 over Q1, based on the forecast, we see that improvement continuing. When we take that recipe of opening up and we look at the data and look at the U.S. and Europe, which is over 70% of the historical UR business, we're very encouraged. We are seeing business development activities.
We are seeing growth coming, really the baseline is China and business activity in the U.S. as well as Europe. From a product perspective, from the applications, we're continuing to invest. We recently have launched in April our ActiNav for bin picking, and we continue to drive for ease of implementation activities and really growing the ecosystem.
Just as a follow-up, at that $59 million revenue for IA in the quarter, how did you manage, again, if I do the math quickly, and your gross margin is still hanging out in the high 50s, maybe to 60%, how did you manage the OpEx in the quarter for IA, and how far from profitability were we in the quarter at the operating level?
I think I mentioned earlier in 2019, we were profitable, and our full-year plan in 2020 pre-COVID was a heavy investment year in IA, both on the engineering side as well as the go-to-market side. We still planned in IA to be profitable at similar levels in 2020. COVID hits. We're faced with a situation of not having the revenue growth. We metered down a lot of the go-to-market spends, and that was a significant reduction. However, we continued forward with the engineering and application spends significantly. What you're seeing in the immediate short term, aside from kind of the revectoring that we did in metering down kind of the selling and marketing or go-to-market spending, is you're seeing more and more online marketing, more and more virtual trade shows, et cetera, and kind of restricted travel, obviously.
You're seeing a short-term reduction in selling and marketing spend. However, you are seeing a little bit of travel and those types of costs within the engineering ranks, but we're continuing to significantly invest on that front.
As far as how close to profitability?
I don't believe in 2020 we will. It's very uncertain depending on the revenue levels in the back half of the year.
Okay.
We're teetering on it. It just really depends on the top line. I want to reiterate that we are encouraged by the activity of Q3 and as well as the ramp-up of China for UR in Q2, and we expect that to continue.
Okay.
Thank you.
Operator, we are out of time. Those in the queue, I will get back to you at the conclusion of this call. Thanks everyone for joining us today, and we look forward to talking to you in the days and weeks ahead. Bye-bye.
Ladies and gentlemen, this concludes today's conference. Thank you for your participation, and have a wonderful day. You may all disconnect.
