Jean-Marc Chery - President, CEO, Acting President of Human Res. & Corp. Social Resp, and Member of Managing Board
Thank you, Celine. Good morning, and thank you for joining ST on our second quarter 2020 earnings conference call. I trust that you, your families and your colleagues are staying safe and healthy, especially those localized in most infected region.
Now to ST results and plans for the rest of the year, let me begin with some opening comments starting with Q2. During the quarter, we returned to normal operations, supporting our customers' demand and continuing to ensure the health and safety of our employees.
Net revenues were $2.09 billion, down 6.5% on a sequential basis. As expected, this was due to a decline in Automotive, Analog and Imaging products, partially offset by growth in Microcontrollers, Digital and Power Discrete. Gross margin at 35% included 310 basis points of unsaturation charges. Our operating margin was at 5.1% and our net income was $90 million.
For the first half of 2020, net revenues grew 1.6% year-over-year to $4.32 billion, driven by higher sales in Analog, Imaging and Microcontrollers, partially offset by lower sales in Automotive and Power Discrete. Our operating margin was 7.8% for H1 2020 and our net income was $282 million.
Looking at Q3 2020. At the midpoint of our guidance, we expect net revenues in the third quarter to be about $2.45 billion, representing sequential growth of about 17.4%. Gross margin is expected to be about 36% at the midpoint, and includes about 200 basis points of unsaturation charges.
For the full year 2020, we will drive the company based on an updated plan for full year 2020, net revenues in the range of about $9.25 billion to $9.65 billion, with growth in the second half over the first half to be in the range of $610 million to $1.01 billion. We expect this growth to be driven by engaged customer programs, new products and improved market conditions. Our CapEx plan for 2020 is now $1.2 billion. For H1 2020, we invested $578 million.
Now let's move to a detailed financial review of the second quarter. The quarter was impacted by the weak demand environment, especially in automotive as well as the operation and logistics challenges due to the governmental regulations related to the COVID-19 outbreak that started in Q1 '20.
Net revenues decreased 4% year-over-year, with lower sales in Imaging, Automotive and MEMS, partially offset by higher sales in Microcontrollers, Digital, Analog and Power Discrete. Year-over-year sales to distribution increased 9.7% and sales to OEMs decreased 9.7%. On a sequential basis, net revenue decreased 6.5%, 380 basis points better than the midpoint of the guidance we gave at the end of April.
By product group, revenue increased sequentially for MDG, while ADG and AMS decreased. Our gross profit was $730 million, decreasing 12.2% year-over-year. Gross margin was 35%, decreasing 320 basis points year-over-year, mainly due to unsaturation charges, including the impact of COVID-19 workforce-related restrictions and price pressure. More specifically, unsaturation charges were 310 basis points. Our second quarter margin was 40 basis points higher than the midpoint of our guidance as unsaturation charges were better than expected.
Moving on to net operating expenses. As we outlined last quarter, we are maintaining strict discipline on expense control while protecting our R&D, sales and marketing programs and transformation initiatives. Net operating expenses at $620 million were below what we anticipated when entering the quarter. Our second quarter operating margin was 5.1%, decreasing by 390 basis points on a year-over-year basis. Both ADG and AMS operating margin decreased, while MDG's operating margin improved. Our net income decreased to $90 million and EPS to $0.10 compared to $160 million and $0.18, respectively, a year ago.
Turning now to the revenue performance of the product groups on a year-over-year basis. ADG revenues decreased 17.8% on weaker demand in legacy Automotive, while Power Discrete grew. AMS revenues decreased 10.1%, with MEMS and Imaging lower while Analog sales were higher. MDG revenues increased 24.1%, reflecting strong growth in Microcontrollers.
In terms of operating margin by product group on a year-over-year basis. MDG operating margin increased to 15.9% from 7.6%, while ADG operating margin decreased to 2.3% from 8.2% and AMS operating margin decreased to 9% from 10.7%.
Net cash from operating activities increased 19.4% to $387 million in Q2 compared to $324 million in the year ago period. Free cash flow was a positive $28 million, including CapEx of $312 million, compared to a negative $67 million in the year ago quarter.
During Q2, we paid cash dividends totaling $37 million and executed a $63 million share buyback as part of the company's previously announced share repurchase program.
Moving now to our business and end market review, let me start with a comment. During the second quarter, we returned to normal operations, supporting our customers' demand and continuing to ensure the health and safety of our employees. This has been our priorities since the start of the pandemic. In preparation for the return of all our employees to our sites worldwide, we put in place very strict safety protocols. Today, we are back to full operation of our manufacturing activities worldwide. Our nonmanufacturing employees located in areas still under specific restrictions are progressively returning to our offices in line with local regulation. Our back-to-site plan, coupled with the engagement of our employees, enable us to keep all our committed programs on track and to maintain a high level of customer interaction.
So let's now discuss the market and business dynamics. The automotive market was hit by closures at carmakers and Tier 1s at different times across the globe. First, China in Q1, followed later by Europe and the U.S. Q2 is considered to be the bottom, and the market was worse than expected with lockdowns extended in some regions. China can see a recovery, partially compensating for the worst situation in Europe and in U.S. We have started to see benefits from automotive incentives in France from June and South Korea for the full year, supporting the anticipated recovery in Q3 and Q4. The legacy automotive market is clearly suffering, amplified by the pandemic situation. We did not see and do not see any substantial slowdown of customer activity as far as the long-term megatrends and ST's strategic growth driver in smart mobility are concerned.
Electrification and digitalization. In car electrification, we had again a number of new design wins for silicon carbide MOSFETs, in a traction invertor and in an on-board chargers and DC-DC converter for electrical vehicles. We are also seeing opportunities for silicon carbide in electrical vehicles beyond these areas. An example is climate compressors, where the current statistics of silicon carbide, allowing to address deficiency and side challenges in this specific application.
Beyond car, we also had an important design win for a battery management system for e-bikes, a real growing area. Overall, our silicon carbide engagement with customers has increased during the quarter. There were no slowdown in already awarded project. And as of today, we are engaged with 58 customers in 64 ongoing programs. These programs are split around 50-50 between automotive customers and industrial customers.
Moving to car digitalization, where we are focused on technologies and solutions for driver assistance and autonomous driving, V2X communications and embedded processing solutions supporting new car architectures. During Q2, we saw a continuous flow of power for our 28-nanometer Phase Change Memory microcontrollers, Stellar, driven by the evolution of car architectures. On ADAS, we saw a strong Level 2 and Level 3 adoption in mid- and entry-level cars. We expect that during 2021, 1/3 of cars produced will have a vision-based system using ST technology. We are also growing our share in automotive microcontrollers, including those for 77 gigahertz radar applications.
During the quarter, we also won sockets for our global shutter automotive imaging solution for driver monitoring system from 2 major OEMs. And this is an important step in our diversification strategy related to optical sensing solutions.
Moving now to Industrial. The dynamics of the Industrial market remains mixed. Some applications like home appliances and lighting are still weak. But during the quarter, we started to see some positive signs in key application areas for ST, such as renewable energy and factory automation. Distribution is an important element of our go-to-market strategy in Industrial. Here, the overall situation in the channel has improved.
In Asia, and mainly in China, point of sales trends were strong sequentially and now also up year-over-year, with a healthy level of inventory in our distribution channel, especially for Microcontrollers and MEMS. From April, we also started to see positive signs for Analog and Power Discrete. America and Europe are still weak. Point of sales on a year-over-year basis is not improving, and inventory levels are still somewhat high in general purpose analog and industrial power conversion. We address the Industrial markets with our general purpose and secure microcontrollers, analog and sensors, power and energy management solutions.
One of our objective in Industrial is leadership in analog processing solution. We recently made 2 acquisitions to further strengthen the wireless connectivity capabilities of our STM32 microcontroller family. These acquisitions cover Narrow Band Cellular and Ultra Wide-band wireless technology from a Riot Micro and BeSpoon. These technologies are key wireless connectivity solutions that will enable a new wave of IoT connected objects and innovative applications, especially in Industrial that complement our existing wireless connectivity offering. We have now shipped over 6 billion parts from our STM32 family. In parallel, we are continuously strengthening our offer in terms of hardware, software and ecosystem. Some examples from the quarter include the launch of the STM32 Digital Power Ecosystem for power supply controls, tools from partners that complement our artificial intelligence capabilities and software packages that simplify development of safety critical products.
Another strategic objective is to accelerate our growth in analog and sensors for Industrial. In Q2, we won several new designs with our analog products for industrial applications. For example, we received awards for motor drivers and smart power products from industrial equipment, lighting and on appliance makers as well as metering customers. And in industrial sensors, our new industrial grade inclinometer was adopt by multiple large customers.
We are targeting expansion in industrial power and energy management. And with our Power Discrete products for Industrial application, we learned the design wins for high-voltage MOSFETs in power supply, solar, lighting, adapters and on appliances. We also captured several awards with silicon carbide again, IGBT and Intelligent Power Modules for motor control, charging stations and renewable energy. We also had design wins with our power management, IC, combined with an STM32 standard microprocessor.
Moving now to the personal electronic market. Despite the slowdown in consumer demand for smartphones during the quarter, we saw increasing demand for anything related to accessories, wearable, gaming and continued innovation-driven semiconductor demand for smartphones. We sell this market with our sensors and secure solutions, power management, analog and front-end modules. We lead in a number of very specific high volume smartphone applications as well as in wearable, such as smart watches, wireless stable wearables and gaming devices. We also aim at capturing opportunities in 5G with RF [mix signals].
During the quarter, we won numerous new designs and ramped production of our products in the flagship devices, including an increasing number of 5G models. Some example of our products include motion sensors, time-of-flight ranging sensors, secure solutions such as ECM and secure elements with NFC, touch display and wireless charging products. We ramped production of our new multi-pixel direct time-of-flight sensor for world-facing camera application in a new flagship device for a global smartphone leader.
In communication equipment and computer peripherals, during Q2, we saw solid market demand for our design for servers as well as continued demand for 5G-related products. Our strategic approach to this end market is focused on cellular and satellite communication. We were awarded a design base on ST propriety technologies for a processor for a satellite application as well as several RF projects for telecommunications infrastructure.
Now let's move to a discussion of the third quarter and brief comments on the full year 2020. For the third quarter, we expect net revenues to be about $2.45 billion. This sequential growth of about 17.4% will be driven by engaged customer programs, new products and improved market conditions. Gross margin is expected to be about 36% at the midpoint and includes unsaturation charges of about 200 basis points fully related to demand.
For the full year, I outlined earlier our sales and operating plan to drive ST to 2020 net revenues now in the range of about $9.25 billion to $9.65 billion, and for growth in H2 over H1 between $610 million and $1.01 billion. This plan reflects an improvement compared to the previous range of $8.8 billion to $9.5 billion we expected entering Q2. Our CapEx plan for 2020 is now about $1.2 billion.
Before concluding, I would like to share with you our updated plans and time line for our Capital Markets Day. During the ongoing pandemic, we will be conducting a virtual Capital Market Day, and it is not prudent to host a physical event. And we are aware that some of you are not yet in a condition to travel. With this decision, we decided to break the event into 4 separate modules, 3 of them covering ST product group strategy and road map, the fourth will focus on the overall company strategy, including our financial model. The preliminary schedule is as follow: MDG, September 15; ADG, November 6; AMS, November 20; and overall strategic update, December 9.
To conclude, I would like to reinforce 2 key points. But first, while we continue to ensure the ongoing health and safety of our employees in response to the global pandemic during last quarter, we have returned to normal operations. Our Q2 results, along with our Q3 guidance, are a clear reflection of that.
Second, ST fundamentals are solid. The strategic decisions we made years ago have enabled us to successfully serve secular growing market trends, addressing key societal deals. We work alongside our customers both for the short and the long term. We are determined to continue to make ST stronger by consistently executing our strategy quarter-after-quarter with a clear sales and operating plan.
Thank you. And we are now ready to answer your question.

(Operator Instructions) The first question comes from Achal Sultania from Crédit Suisse.
Achal Sultania - Director
Maybe can you provide some color on the inventory side? I guess you're still running at a very high inventory on your own books. I think last quarter, you mentioned that you have a plan to get it down to about 100 days by the end of this year. So are we still looking to achieve that target by end of 2020?
And then secondly on this Huawei impact, like I just want to understand how much of that Huawei impact is in your guidance for second half of this year or is it something that you're still assessing how that situation unfolds, and at this point, it's very difficult for you to assume some of that impact in your second half guidance.
Jean-Marc Chery - President, CEO, Acting President of Human Res. & Corp. Social Resp, and Member of Managing Board
Thank you. So Lorenzo will answer the first question, and I will answer the second one.
Lorenzo Grandi - President of Finance, Infrastructure & Services and CFO
Lorenzo speaking. Thank you for the question. During the second quarter, actually, our inventory increased. During the second quarter, for sure, one of our priorities was, let's say, back to manufacturing of our people. And indeed, we ran a little bit better than expected. As you know, our saturation charges, that came lower than what was our original expectation entering the quarter. So at the end, the inventory at the end of the second quarter was in the range of 129 days of investment.
In the second half of the year, we will continue to monitor our inventory. And indeed, with the level of unsaturation in the second part of the year, we'll continue to be presented with around 200 basis point, both in Q3 and in Q4. And I do expect, let's say, that in Q3, our level of inventory and the number of days will go down in a range of between 115 and 120 days. And I do expect for Q4 to go back to the level that I was mentioning already during the first quarter earning release in the range of 95 to 100 days.
Jean-Marc Chery - President, CEO, Acting President of Human Res. & Corp. Social Resp, and Member of Managing Board
Thank you, Lorenzo. So about Huawei, I would like to highlight again that we address this customer following our strategy of selective approach on personal electronics and communication infrastructure. Okay, the products that we sell them are all within our strategy clearly. And among the products that we ship to them, there are custom solutions, application-specific standard product and general purpose products. But clearly, again, we acknowledge at the May 15, 2020, announcement by the U.S. Bureau of Industry and Security, ST will simply comply with the laws and applicable regulation as we continue to support our customer. We had no impact in Q2. We do not have any impact in Q3. And we will have some impact in Q4, which is already embedded in the indication we have given for the full year 2020 plan. I hope it answer your question.

The next question comes from Andrew Gardiner from Barclays.
Andrew Michael Gardiner - Director
I just had one high level one. So regarding your level of visibility at the moment, and if we could perhaps contrast it to this time 3 months ago. At that time, back in April, you talked about pushing back on your customers in terms of scrubbing the orders, scrubbing the backlog to make sure that it was reasonable given the kind of end demand that we are all seeing. How do you feel about that at the moment? How is the order book? Are those good orders? Are you worried about double ordering? There has been some talk about inventory being built by one of your closest peers within the supply chain, given fears over further disruption due to the pandemic. Just sort of how can you -- yes, give us a bit more detail in terms of the level of visibility you have into the back half at this point.
Jean-Marc Chery - President, CEO, Acting President of Human Res. & Corp. Social Resp, and Member of Managing Board
So I will take it and Marco Cassis will complement. Now yes, okay, we confirm the situation entering in Q3. It's completely different the one entering in Q2. Well, in Q2, our, let's say, book-to-bill ratio has been well below 1 because impacted by the correction in automotive. And correction, okay, we have driven, okay? Yes, okay. We confirm that we have taken the initiative entering in Q2, okay, to discuss very closely with our customers, so the Tier 1, and really to clean the backlog and to align the backlog, okay, with the consumption of products they have from consignment stock. So entering Q3, the backlog is clean for all the verticals we address. So automotive industry, all personal electronics and communication infrastructure too and computer peripheral. But saying that, okay, we have a solid visibility of the backlog in Q3.
Again, I made the comments about the POS, okay, growing sequentially and now on the year-over-year in Asia. Well, yes, okay, we see Europe and America still weak. But all the data point, okay, usual data point we have in our end, which are, again, the backlog, the POS, okay, now are really clean. The inventory level and distribution in Asia is clean, okay? There is no other inventory. We start also some signs of positive on Analog and on Power Discrete on top of microcontroller and MEMS. So we are very confident, okay, in the visibility we have. Then again, okay, top 10 customer are an important part of our business. Here, okay, we have a very close intimacy on the supply chain and we have the adequate visibility. All together between the backlog and the customer intimacy, okay, make us confident on the guidance we provided for Q2.
Marco Luciano Cassis - President of Sales, Marketing, Communications & Strategy Development
Yes, Jean-Marc. And let me just add a little bit of information. In April, our sales and operating plan was based on visibility for the full year of some, the market that we serve, that was going to be between minus 5% and minus 13%. Now we have updated and upgraded our view to a sum that will be between minus 5% to minus 7%, in line with all the indicators that we are getting from our key customers and the evolution, as Jean-Marc has already said, of our POS and POP through distribution. Again, distribution is key because one market that we are focusing on in our strategy is clearly the industrial market, and this market is extremely fragmented. So the performance of the distribution channel there is a very good indicator of how things are evolving.
Clearly, industrial is still mixed. We have applications that are still suffering like we said before, like lightning and home appliances, but we saw a good improvement and recovery coming from other applications that are extremely important for ST, like renewable energy and the factory automation. So there again, China is leading the back because, as you know very well, in terms of timing, China was hit first. So the main impact was in Q2 -- in Q2 -- in Q1, sorry. In Q2, there is a very good recovery, sequentially strong and also year-over-year in terms of POS. And again, underlying that the stock level is absolutely under control. Thank you.
Operator
The next question comes from Matt Ramsay from Cowen.
Matthew D. Ramsay - MD & Senior Technology Analyst
I wanted to dig into the ADG business a bit because there's been some moving parts in the last couple of quarters with the manufacturing challenges in discretes in Q1 and then maybe those recovering in the second quarter with the auto business being down pretty dramatically in Q2. Maybe you could break that business down a little bit and let us know what your expectations are for those 2 segments of that piece of the business into the third quarter. And then if you have any comments, I think Texas Instruments talked about the other night, the month of May, in particular, being the bottom for their automotive business that they saw down, I think, 40% in the quarter. Are you seeing those same trends?
Jean-Marc Chery - President, CEO, Acting President of Human Res. & Corp. Social Resp, and Member of Managing Board
Maybe I'll start to answer again, and Marco will complement. Now it is clear that in Q2, for ADG, we have, let's say, different dynamics. Well, first, Power Discrete recovered very, very strongly, first, because of the free of supply chain constraints related to the, let's say, labor workforce in the various plants where we have been impacted. And the main one was the closure of Shenzhen definitively and limited workforce attendance in [Muar] and in [Bouskoura], impacting strongly Q1.
Q2 was free of, let's say, this shortage of capacity linked with the COVID-19. So first effect, overall, okay, power discrete recovered strongly in Q2 with the supply chain coming back to normal operations. But then again, inside Power Discrete, we have, let's say -- you know that now we are very wide in the portfolio, okay, from a high-voltage PowerMOS, low-voltage PowerMOS, IGBT, silicon carbide MOSFET, and okay, some discrete, okay. And discrete, we have, okay, some, let's say, integrated passive and active delight addressing, okay, the ARS part on personal electronics. Now all this mix of product, okay, the dynamic was very positive. And for various reason, but more silicon carbide, I guess you know it's because of electrification of the car, IGBT as well, low-voltage PowerMOS as well for 48-volt application. So makes, okay, Power Discrete, okay, really strong in Q2 versus Q1. And this dynamic, okay, will continue in Q3.
Well, about automotive, well, clearly, automotive for ST, what was running well is ADAS with the partnership we have with Mobileye, okay, which really show, let's say, a very good dynamic in Q2 and will continue in Q3.
Well, about legacy automotive, the pure legacy automotive means application-specific ICs, okay, analog or, let's say, microcontroller for legacy automotive. But definitively, okay, Q2 has been, let's say, a very challenging quarter. We took the initiatives, as I have said, to push our customer to clean their portfolio in order to be sure that in Q2, we will not build at their level, okay, inventory and our inventory in consignment stock. Well, and as a matter of the result, we have a very strong decrease in legacy automotive Q2 over Q1 above 20%.
Now what we have seen in term of dynamic, late June and early July, okay, the run rate of consumption from the consignment stock, okay, is starting to rise up. And in Q3, I can confirm to you that, including the legacy automotive, we will see a growth sequential. Means we confirm and I confirm in my address that we are convinced that Q2 is a bottom, okay, of legacy automotive, and we will start to see, okay, market recovery, Q3, and most likely acceleration after the summer period because you know that, generally speaking, okay, mainly in Europe, okay, the carmaker and then Tier 1 are closing for vacation period their plant. And we will certainly see, okay, an acceleration in September and Q4 onward.
So this is the color I can give to you, and Marco can complement it.
Marco Luciano Cassis - President of Sales, Marketing, Communications & Strategy Development
Yes. I will just complement with some extra data point. As you have underlined, clearly during Q2, the automotive market was badly hit. But let's not forget, this was linked with the closures of carmakers and Tiers 1. So mechanically, it was impossible to have production. And also that demand was strongly hit by the fact that mobility of people was extremely low. It's also true, by the way, that during Q2, we saw different dynamics in China. China like went out of the coronavirus situation during Q1. And in Q2, as you know very well, the demand in terms of cars in China has rebounded more or less with this shift. So again, Q2 due to these dynamics is surely the bottom. And from Q3, as Jean-Marc say, we start seeing a recovery.
Let me underline also that we expect to see benefits coming from the incentives that the various governments are putting in place, for example, in France and in South Korea. And important to underline another point is that we don't see any substantial slowdown of the customers' activity for what is related with our longer market trends and what is for ST's strategic -- other strategic growth drivers in smart mobility, which are related to electrification and digitalization. So again, Q2 was the bottom. And from Q3, we start seeing in the recovery.

The next question comes from Janardan Menon from Liberum.
Janardan Nedyam Menon - Technology Analyst
I just wanted to examine the medium-term target of $12 billion of revenue that you've talked about previously and given the stronger-than-expected trends that you're currently seeing through the second half of the year. What your thoughts are on that right now? Can we assume that you still have a fairly unchanged time horizon for meeting that compared to your previous comments, including your Capital Markets Day last year? Or has there been any shift in it? I think you had referred to a possibility of meeting that on an annualized run rate basis by the second half of '21. Would that be still a possibility?
And secondly, on your general purpose Microcontroller business, the MDG revenue was -- has grown at 24.1%. And I would assume that a lot of that is from the general purpose of Microcontrollers. So clearly, that is doing at least close to the mid-20s of growth rate. Is that a market growth rate in your estimation? How much of that would be market share gains? And where -- what kind of applications do you think is driving this most predominantly?
Jean-Marc Chery - President, CEO, Acting President of Human Res. & Corp. Social Resp, and Member of Managing Board
Well, so I will answer the first question and start to answer the second, and Marco will complement. Now about the $12 billion, well, it is clearly our target, okay, the management target, okay, of our next 3-year sales and operating plan we are working on because you see the exercise, okay, we rework and update every year. Now about this timing, when it will be achieved inside the 3-year, now I guess, okay, you will share with me that it deserve a bit some assessment and analysis now to, let's say, better understand the implications of the legacy automotive market and when the production of light vehicle, okay, will come back to the 2019 level and as well to understand the implication related to the U.S.A.-China trade war. But again, I confirm, okay, yes, $12 billion, okay, will be achieved, okay, within the next 3 years.
About microcontroller, clearly, microcontroller growth is not only general purpose. It's also a secure microcontroller, both with automotive and secure solution within ST. With microcontroller, it is as well both 32-bit and 8-bit. And also I would like to highlight and again and recall you, because this is something we shared with you during the various communication we have all together, that last year, we introduced, okay, 10 new products. And from, let's say, ultra-low power microcontroller, well suitable for IoT kind of consumer application and high performance, let's say, microcontroller, well suitable for industrial application.
Now on top of that, okay, we are continuously improving the ecosystem around the microcontroller. So between new product introduction, let's say, the ecosystem, our supply chain, okay, because, also, microcontroller are using 50-50, okay, internal manufacturing of ST and external, let's say, well-known important family. Our selection has been very strong, okay, also during this period. So I repeat that, ourselves, we never closed any wafer fab. And our partner, our foundry, never closed any wafer fab. We have been successful to manage as well as the OSAT and our internal assembly and test.
So all in all, okay, this is the reason why, okay, we are growing on microcontroller, which is, let's say, the add-on of new product introduction. Inventory clean and distribution channel, very good recovery in 8-bit and a very strong supply chain, which go through this pandemic outbreak challenges without any disruption. So this is all the enabler making ourselves growing at this level and having this leadership position.
So maybe, Marco, you want to add something?
Marco Luciano Cassis - President of Sales, Marketing, Communications & Strategy Development
Yes. So just to reprice trades to one of your point, yes, we have gained market share and in our microcontrollers. And this is, as Jean-Marc was saying, mainly linked with the fact that we have transformed the funnel of opportunities that we have created during the last year, et cetera, with the new family of microcontrollers. And we are leveraging on our leadership position in microcontrollers, which means our reach of customer, small customer and big customer through the distribution channel, it's clearly helping us to gain ground in the microcontroller domain.

The next question comes from Jerome Ramel from Exane BNP Paribas.
Jerome Ramel - Analyst of IT hardware and Semiconductor
Two quick one. The first one, how should we model the OpEx for the coming quarter?
And second question, Jean-Marc, you mentioned a time-of-flight for wall spacing. Could you elaborate a little bit? When is the timing of its ramp-up? Is it a direct or indirect time of flight?
Jean-Marc Chery - President, CEO, Acting President of Human Res. & Corp. Social Resp, and Member of Managing Board
Yes. Thank you, Ramel. So Lorenzo will take the first question, and I will take the second.
Lorenzo Grandi - President of Finance, Infrastructure & Services and CFO
Sure. I will take expenses and how to model the expenses for next quarter and the following one because, at the end, at this stage, you see that, on Q2, our expenses -- and when I talk about expenses, I always include also the line other income and expenses. Overall, so net expenses came at $620 million. This $620 million was a little bit better than the expectation entering the quarter, if you remember. And this was mainly driven by the fact that, of course, the lockdown plays a little bit in favor to have lower expenses with a significant reduction in traveling and some reduction also in discretionary expenses.
Moving inside the third quarter, my expectation is that expenses will be more in a range that is our average range -- quarterly average range for the year that I still confirm in the range of $635 million to $645 million per quarter. So it means that there will be some increase in expenses moving from Q2 to Q3. I do expect that we'll be more or less at the midpoint of this range what I was mentioning, while confirming the total -- this range for the full year. For the full year, if you take our expenses in the full year and you divide it by 4, our average should be there, between $635 million to $640 million per quarter. So this is confirmed, notwithstanding some acquisition that we are doing. So it means that we do not expect that this will increase our level of expenses.
Jean-Marc Chery - President, CEO, Acting President of Human Res. & Corp. Social Resp, and Member of Managing Board
Well, about -- we have started production, so -- because this device will be introduced on a new flagship. So in order to be ready with the supply chain when the flagship will be introduced in the market, okay, we have started the production now. I can mention it is addressing the [unrolling front]. And it is based on our, let's say, multi-pixel still direct time-of-flight technology, what we call our SPAD technology, so single-photon avalanche diodes. And I already mentioned in the past that it can address, okay, world real-facing application. And here, you know that on this world real-facing application, you will have, okay, both technologies with, of course, different features. So multi-zone and multi-pixel direct time of flight, and you will have as well indirect time of flight. So this is what I can disclose, Jerome, at this moment.

The next question comes from Sébastien Sztabowicz from Kepler Cheuvreux.
Sébastien Sztabowicz - Head of Tech - Equipment Research
On your full year guidance, slightly declining over the full year, where do you see the 3 divisions evolving over the full year? Which one are likely to outperform and underperform your main target?
And coming back on silicon carbides, can you help us understand what was the level of revenue you have already generated in the first part of the year? And what is your view or your updated target for the full year? Do you think there is still a chance to come closer to $300 million of revenue? Or it is a bit too optimistic taking into account the slow start of Q1 in silicon carbide?
Jean-Marc Chery - President, CEO, Acting President of Human Res. & Corp. Social Resp, and Member of Managing Board
So I take the question, and again, my colleagues, okay, will complement. On our silicon carbide, you remember in April during our meeting conversation, unfortunately, what we have lost in Shenzhen, okay, cannot be recovered. This is the point. But here, okay, while this is not something we will update regularly because it is not, let's say, a very regular KPI we monitor, but if you remember well, I share, okay, with you, okay, last quarter that we assessed to have a PVO between 2020 to 2024 of about $2.8 billion on silicon carbide, well shared between automotive and industrial. Now with the design win we have during Q2, now, okay, we assess this PVO to be above $3 billion, which is showing our dynamic. But for this year, unfortunately, what we lost in Q1 are definitively lost.
Then about the full year, Lorenzo can disclose the...
Lorenzo Grandi - President of Finance, Infrastructure & Services and CFO
Maybe I can take your question. When we look at full year and I refer in term of the revenue what is the midpoint of our indication that is in the range of $9.45 billion, how is the dynamic between the 3 segments? Well, there are 2 segments that will increase. One is MDG. MDG will increase revenue on the -- in the range of the high single digit, and this is mainly driven by our microcontrollers, both general purpose and secure. We see also growth in AMS. In AMS, we have a growth that will be in the range of low single digit, and this will be driven by imaging and analog.
Why we see declining revenues in ADG? ADG will be definitely impacted by the situation of the market in automotive, even if there will be a recovery in the second part of the year in respect to the first part of the year. Still looking at the overall year, we will have a decrease, and this decrease will be in the range of the low teens. Overall, the company will be in the range of minus 1, 1 or 2 is our, let's say, indication for this.
Celine Berthier - Group VP of IR
We are running short of time now. We have time for 1 or 2 more questions, 2 more questions, if you don't mind. As usual, for the ones that have other question, Investor Relations team is ready to answer separately after this call, and do not hesitate to reach out.

The next question comes from Gianmarco Bonacina from Equita.
Gianmarco Bonacina - European Equity Research Manager
Just a clarification on the gross margin for the full year. In the previous call, you mentioned the range of 35% to 37%. Now clearly, the midpoint of your sales range for the full year has increased. So shall we think for the full year gross margin closer to the 37%?
Lorenzo Grandi - President of Finance, Infrastructure & Services and CFO
Well, at this stage, as we said, the gross margin that we see today with this second half impacted by an average of 200 basis points of unloading charges in both quarter, Q3 and Q4. As I said, the gross margin, we see something in a range between 36% to slightly above 37%. So of course, it will depend on the level of revenues that we will achieve. In term of unsaturation, in term of production plan, it will not change dramatically because, of course, our lead time in order to fill our fab will not be -- is such that, of course, the degree of freedom that we have in order to modulate that production is not so big. So we -- our expectation is to be between really 36% and slightly above 37% at the highest level of our revenues.
Gianmarco Bonacina - European Equity Research Manager
Okay, for the full year?
Lorenzo Grandi - President of Finance, Infrastructure & Services and CFO
For the full year, yes, of course.
Celine Berthier - Group VP of IR
So the last question now, please, Alessandro.

The last question comes from David Mulholland from UBS.
David Terence Mulholland - Director and Equity Research Analyst - Technology Hardware
I just wanted to follow-up on the far away situation. Obviously, you said there's a lot of business today that's standard products. There's no issue, but there is some that's custom. I just wondered, is that something that there's such engagement and level of custom to that? It just has to go away or is it something you can transition while still adhering to the rules to become a kind of standard product business with enough time to develop a more standard solution, if I can put it that way?
Jean-Marc Chery - President, CEO, Acting President of Human Res. & Corp. Social Resp, and Member of Managing Board
Now again, okay, we address this customer, okay, with various, let's say, operating model, okay, from custom design to application-specific and the general purpose device. There is no, let's say, order approach, again, than to be compliant with what will be confirmed because we were expected to have a clear detail and confirmation mid-July. That is still not the case. And I have, honestly, no other comment, okay, than the one I have done a few minutes ago, answering the question.
Celine Berthier - Group VP of IR
Okay. So that will conclude our call. Thank you very much, everybody. Have a nice earnings season for every one of you that are engaged in that. And we speak at the next...
Marco Luciano Cassis - President of Sales, Marketing, Communications & Strategy Development

Jean-Marc Chery - President, CEO, Acting President of Human Res. & Corp. Social Resp, and Member of Managing Board
And even the Capital Market Day.
Celine Berthier - Group VP of IR
Yes. And yes, I need remind you in the address, Jean-Marc has been talking about the various appointment we've put for the Capital Market Day. So the next one before our earnings, yes, thank you, is the one with Claude Dardanne to discuss MDG on the 15th of September. This will be our next event from an -- even if, again, it is virtual. So hopefully, this will be easier than to travel around the world to meet with us.
Jean-Marc Chery - President, CEO, Acting President of Human Res. & Corp. Social Resp, and Member of Managing Board
