Good morning. This is Robert Yi from Investor Relations. Thank you for joining our earnings call for the second quarter of 2019. With me representing each of the business units are Mr. Chun SeWon, Executive VP of Memory Marketing, Mr. Hur Gok, Senior VP of System LSI, Lee Sang-Hyun, VP of our Foundry, Choi KwonYoung, VP of Samsung Display, Lee Jong-Min, VP of IT and Mobile, Kim WonHee from the Visual Display Business, as well as Mr. Seo Byung-hoon and Kang Tae-gyu, both from Investor Relations. I would like to remind you that some of the statements we'll be making today are forward-looking based on the environment as we currently see it, and all such statements are subject to certain risks and uncertainties that may cause our actual results to be materially different from those expressed in today's discussion.
The total revenue in the quarter decreased 4% year-on-year to KRW 56.1 trillion, as sales in the memory business declined due to weak market conditions. As forecasted in the previous earnings call, business conditions for the memory industry remained weak in the second quarter, even though there was some recovery in market demand. Gross profit fell sharply year-on-year to KRW 20.2 trillion with a corresponding decrease in gross margin, mainly due to the semiconductor business. Compared to last year, SG&A expenses had a small increase in both absolute terms and as a percent of sales. Excuse me. The operating profit in the second quarter was KRW 6.6 trillion, a significant year-on-year decrease, mainly based on challenges in the memory and mobile businesses. One-off gain from display business is included in the earnings. Operating margin came in at 11.8%.
A strong U.S. dollar and euro against the Korean won in the second quarter positively affected the operating profit quarter-on-quarter by approximately KRW 0.5 trillion. I will now briefly review the performance of each business unit. In the Memory Business, as the effect of inventory adjustments by major data center customers in the previous quarters continued to cause weak market conditions and price decline, we placed a heavier focus on addressing demand in the mobile segment. For System Semiconductors, earnings were lower year-on-year despite growing demand for major products such as image sensors due to a decline in demand for cryptocurrency applications. In the Display Business, mobile panel earnings improved due to a one-off gain and increased sale of rigid panels. The large panel business, however, recorded a slightly larger loss year-on-year as ongoing capacity expansions in the industry weighed on profitability.
In the IM business, a strong sales by the new mid and low segments devices helped increase overall smartphone shipments, but mobile profitability declined due to slower flagship sales, major spec enhancements of the new mid and low segment devices, and an increase in marketing expenses. In the network business, earnings remain solid due to accelerated commercialization of 5G in Korea. For the CE division, earnings in the TV business fell slightly year-on-year amid aggressive competitor pricing, despite growing unit sales of premium models such as QLED and ultra-large models. For digital appliances, earnings grew with the strong sales of new products, coupled with improved profitabilities of our mainstream products such as refrigerators and washing machines. I would like to share our business outlook for the second half of the year.
In the semiconductor business, even though continued industry uncertainties are causing low visibility in the business, we do expect memory demand to grow on the strong seasonality and adoption of higher density products in major application areas. For system semiconductors, seasonality is likely to boost demand for mobile APs, image sensors and OLED DDIs, among other products. In the display business, we expect earnings for mobile panels to improve, thanks to growing sales and a resulting rise in utilization rate led by launches of new products by our major customers. Sluggish overall demand in the smartphone market may limit upside potential. The large panel business on the strong seasonality will focus on high-end products for 8K and ultra-large TVs rather than on volume competition.
For the mobile business, as we expect competition in the second half to intensify with the market seeing many new devices being released, we will bolster our strategic product lineup and also expand sales of our new A series in the low end to mid-range market. We will focus on ensuring the successful third quarter launches of the Galaxy Note 10 and Galaxy Fold, as well as on improving profitability through improved operational efficiencies. The network business will continue to build a strong foundation for expansion in the global 5G market based on its leadership in 5G commercialization in the U.S. and Korea. For the CE division in the seasonally strong second half, we will work to further solidify our lead in the premium TV market by expanding sales of QLED TVs and boosting sales of innovative products such as 8K and lifestyle models.
For digital appliances, we will concentrate on sales of new products such as BESPOKE refrigerators and clothes refreshers. We face various challenges from uncertain conditions, not only in our business areas, but also from growing global macro environment. Despite these current challenges, we will continue our efforts to secure mid to long-term growth by strengthening competitiveness of our new business via delivering innovative component technologies and continuing our leadership as a 5G solution provider. In addition, investments in future technologies such as system semiconductors, artificial intelligence, and automotive solutions will remain a key focus. Now I'll address capital expenditures. CapEx in the second quarter was KRW 6.2 trillion, with KRW 5.2 trillion allocated to semiconductors and KRW 0.5 trillion to display. The total capital expenditure for the first half was KRW 10.7 trillion, with KRW 8.8 trillion allocated to semiconductors and KRW 0.8 trillion to display.
As we explained in previous calls, the main portion of our 2019 CapEx is earmarked for building infrastructure to address demand beyond 2019, and a large percent of this year's investment will be made in the second half. Larger percent , I'm sorry. The board of directors today approved a second quarter dividend of KRW 354 per share to be paid in August for both common and preferred stocks. As was the case in the first quarter, the dividend payout for the second quarter is KRW 2.4 trillion, or 1/4 of the annual total of KRW 9.6 trillion. I would like to talk about our shareholder return plan covering 2018 through 2020. Today, we had planned to provide an update to our shareholder return program based on the review of our projected free cash flow for the three-year period through 2020.
However, in addition to already high uncertainties caused by prolonged global trade conflicts and other macro risks, the external environment regarding our component business has recently come under significant new challenges. As a result, we no longer believe that it is possible to reasonably predict or forecast our free cash flow for 2018 through 2020. We have decided that it would be best to share our update for the shareholder return in early 2020 after free cash flow for 2019 is confirmed and when the business outlook for 2020 becomes more visible. Before we move on to presentations from each business unit, I would like to share several data points in key business areas. In the second quarter, our DRAM bit growth came in mid-teens increase. Our ASP declined low 20%.
For the third quarter, we expect the market demand for DRAM to grow mid-teens, and we expect to grow in line with the market. For 2019, for the whole year, we expect the market demand for DRAM to grow mid-teens, and our bit growth will be slightly higher than the market demand growth. For NAND Flash, for the second quarter, our bit growth came in around 30%, and ASP declined mid-teens. For the third quarter NAND market growth, we expect to be high single digit, and we expect to grow with the market. For 2019, we expect NAND demand growth to be low 30s, and we expect to outgrow that market growth in our bit shipment. Within display panel business, the OLED sales mix was high 70%. For mobile business, our total handset sales for the second quarter was 83 million units, with about 5 million of tablets.
The blended ASP for the second quarter was about KRW 210. A mix of smartphone within total handset was low 90%. For third quarter, we expect our handset shipment to be similar to the second quarter, as well as the tablet to be similar, too. Our ASP for the handset is expected to increase quarter on quarter, and the mix of the smartphone within total handset will remain at low 90%. For our TV business, the LCD TV panel sales in the second quarter declined mid-single digit quarter on quarter. In the third quarter, we expect that number to increase low teens. For the year, we expect our TV sales to increase mid-single digit. Now I'll turn the conference call over to the gentleman from each business unit, starting with memory.
Good morning. This is SeWon Chun from the Memory Marketing team. In the second quarter, overall demand increased due to the resumed purchasing from data center customers, and their inventory levels started to be normalized and high-density trend across overall applications. Front-end, overall demand showed solid growth, backed by the ongoing high-density trend for smartphones due to the price elasticity and by expansion of cloud infrastructure from server customers. While we're focused on demand for products that we have a competitiveness, such as high-density e-storage with more than 128 GB and high-value-added, high-density SSD with more than 2 TB, we actively respond to demand for wafer and component products as well, achieving result much higher than the previous guidance. For DRAM, although the overall market situation remained weak, demand increased from a resumption of purchase in data center customers and from a high-density trend in mobile.
Server demand has been recovered mainly for high-density products, thanks to recovered purchasing after inventory adjustment, especially from data centers and newly launched server CPU. For PC, demand increased both for replacement purchase considering Windows 10 from enterprise PC and for pre-purchasing, considering global uncertainties. For mobile, smartphone set demand has recovered from first quarter, and the portion of high density has increased in overall smartphone segments, resulting in a solid increase in demand. Our sales results exceed our previous expectations as we actively addressed the recovered demand for data center customers and high-density trend for mobile. In the second half of this year, we expect the demand to increase due to seasonal effect, but the market situation is likely to remain volatile due to expansion of global uncertainties, which include export regulations in semiconductor materials.
On end, as awareness of bottom price among customers expand, we think demand will continue to expand mainly for high density, high-value added data center and mobile storage, and the industry will be stabilized gradually from the third quarter. For SSD, adoption for high density, high-performance SSD for data centers is likely to keep expanding. Moreover, both the high-density trend and expansion of NVMe portion for client SSD are also expected to continue due to price decrease. Mobile demand is expected to increase due to the ongoing trend toward high density that has been driven by price declines, especially on the effect of launching high-end smartphone with more than 128 GB.
We are focused on strengthening our competitiveness in the premium market by closely monitoring changes in demand across all applications and by actively responding to demand, both for all flash array conversions in the 10,000 HDD market and for high-density UFS regarding trends to handset makers and flagship models. We are mass producing 5th-gen V-NAND mainly for branded SSD as planned, and we will enhance our technological competitiveness and strengthen our profitability based through the mass production of 6th-gen V-NAND within this year. For DRAM, although global uncertainty remain, overall demand is expected to increase due to a recovery of purchasing from customers as their inventory level normalize and seasonal effects.
For server, we expect the demand to rise gradually, not only from customers resume purchasing as their inventory adjustment completes, but also from conversion to a new platform. For consumer product, TV and set-top box demand is expected to increase by seasonal effects, and high-performance network memory demand is likely to expand along with 5G expansion. For mobile, as major customers will launch the new smartphones, high-density trend in overall segment is expected to drive the solid demand, such as adoption of mobile DRAM with more than 8 GB for product differentiation in volume DRAM. Under the current global uncertainties, we'll actively address customer requests through a flexible product mix and maintain our technical leadership based on 1Y nanometer product ramp-up.
We will focus on strengthening our market leadership of differentiated product, such as 12 Gb-based LPDDR5 and HBM2, by the developing and mass producing in a timely manner. Thank you.
Good morning. This is [inaudible] from System LSI business . In the second quarter, as Chinese smartphone companies have intensified the competition for the camera specs, demand for multiple cameras and high-resolution big pixel image sensors increased more, and we have achieved solid results. In addition, we increased the supply of the 5G and the volume zone smartphone chipset solutions, and we continued our efforts to expand the future SOC technology leadership by developing next generation one chip 5G SOC that integrated modem and processor. In the second half, we expect demand for mobile AP, image sensors, and DDI products to grow seasonally as smartphones enter the peak season. Noticeably, demand for high value-added product is also expected to continue to increase because customers still want to differentiate product by adopting the products, such as 64 megapixel image sensors and EUV seven nano APs, et cetera.
Looking ahead, we plan to expand our lineup of 5G chipset solutions and image sensors to address demand for the high specs in the smartphone market. We will also expand our mid to long-term business scope by diversifying our product offerings through the development of the 3D ToF sensors and automotive IoT chips. Thank you.
Good morning. This is Sang- Hyun Ryan Lee from the foundry business. In the second quarter, we have achieved solid results due to increased demand from major customers' eight, 10 nano mobile AP and image sensors. In particular, new orders from existing major customers have expanded in 10/14 nano process, and orders for new customers have also been awarded. By doing so, the business base for future growth has been further strengthened by diversifying the region from Americas to China, Europe, Japan, as well as the applications from mobile to HPC, IoT, automotive, network, consumer, et cetera. With the technical achievements, we have mass-produced EUV seven nanometer products for the first time in the industry. Further strengthened our EUV process development leadership by completing the development of 5 nano process and preparing for production.
Furthermore, we also distributed the world's first gate-all-around base three nano process development kit to our customers. In the second half, we anticipate continued earnings growth due to the expansion of AP, CIS, DDI orders as the mobile season enters. The demand for HPCs, including cryptocurrency mining chips and new orders from network, ADAS, consumer, will increase. We plan to start mass production of EUV six nano process, which is an optimized process in terms of performance and price. We will also continue to secure advanced node competitiveness by completing the tape-out of EUV five nanometer products and completing four nanometer process development and infrastructure. In addition, we will use our specialty process to take leadership in newly emerging areas such as 5G, AR, and automotive, and expand our customer bases. Thank you.
Good morning. I'm Kwon Young Choi from the business planning team of Samsung Display. In the second quarter, total earnings for the display business improved quarter-over-quarter, led by a recovery in consumer demand and one-off gain. To be more specific, mobile display earnings increased quarter-over-quarter as utilization improved, thanks to expanded shipment of OLED panels, featuring new technologies such as fingerprint on display and hole display. As for the larger display business, despite a continuous drop in ASPs, earnings increases slightly quarter-over-quarter, led by improved cost competitiveness and increased shipments of premium panels, including ones used in ultra-large high-resolution TVs and in curved monitors. Next, I'd like to touch upon prospects and strategies for the second half of this year.
In the mobile display business, earnings are projected to improve half on half, and shipments and utilizations are expected to rise as major customers are planning to launch new products. In particular, we expect to see growing demand for OLED panels offering ultra-slim design. 5G mobile phones require larger components and more of them, so the lack of space issue needs to be addressed. Therefore, we strive to improve our profitability by adding more values to OLED panels and boosting yields. At the same time, we'll keep actively responding to demand from our customers. As major IT customers are about to launch new laptops featuring our OLED panels, we'll add to our foundation tool for sustainable growth by creating new markets in other non-smartphone areas such as tablets and automotives, to name a few.
On the other hand, given the lingering concerns over mounting uncertainties and overall market slowdown caused by the global macro environment, we are closely monitoring the situation to minimize any potential impacts. Although the large display business expects to see growing demand for premium TV panels, such as the ones used in ultra-large UHD and 8K models, capacity expansion in the LCD industry is likely to destabilize supply and demand and add more uncertainty in the market. In preparation for such conditions, we are striving to keep improving profitability. To that end, we are focusing more on premium TV panels and strengthening non-TV business for monitors and public information displays. Thank you.
Good morning. I'm Jong- Min Lee from the IT and Mobile Communications Business. I try to share our second quarter results and the second half outlook for IM division. In the second quarter, followed by the relatively weak season period, overall smartphone demand decreased due to a number of global macro variables. On a quarter-on-quarter basis, our smartphone shipments increased as new A3 series models, including the A50 and A70, showed stronger sales performances than their previous models. The sales volume of flagship models, including those of the S9 and Note9, decreased quarter-on-quarter as the launch of effect of S10 became weaker and the demand for premium segment was shrunk. Profit also decreased quarter-on-quarter because of increased cost associated with intensified competition in the mass market and inventory adjustment of older models.
In our network business, our performance improved quarter-on-quarter, thanks to full-scale commercialization of 5G in South Korea and continued expansion of LTE networks in overseas markets. Now, moving on to the outlook for the second half of this year. Although the mobile market, in general, is soon to face a period of strong seasonality, demand is expected to keep trending down due to growing global macroeconomic uncertainties. We will focus on not only enhancing our flagship lineup, but also expanding sales of our new mid to low segment models as well. Also, we will respond quickly to any changes in the global business environment, such as trade restrictions or changes in the competitive landscape. Furthermore, we will strive to secure profitability through improving the efficiency of our operations in all aspects, from R&D to manufacturing and marketing.
In the third quarter, we are going to focus on ensuring successful launches of Galaxy Note10, the Galaxy Fold. The Note 10 will be officially revealed at our Unpacked event this August 7th in New York. It will offer improved productivity, best-in-class performance, and a differentiated design compared to its previous model. Galaxy Fold, which will be available to customers from September, has improved design and construction to provide the best experience for our customers. We will begin an entirely new mobile category based on our accumulated flexible display technology. We expect that Galaxy Fold will give our customers a completely new experience and create endless possibilities. Along with these innovative products, we aim to strengthen our 5G leadership by expanding our 5G product portfolio to meet the commercialization schedules in each region.
For mid to low-end smartphones, most regions are already showing higher sales, which is clearly due to the impact from the changes in our lineup earlier this year. To keep the momentum going, we are going to expand overall sales by releasing new highly competitive A series models in the second quarter and efficiently leveraging the seasonality in all regions. For the network business, based on our leadership in 5G commercialization in South Korea and the U.S., we will do our best to keep adding to our foundation for global 5G business expansion. Thank you.
Morning, I'm Kim Won-sang from Visual Display Sales and Marketing. Let me start with current market conditions and our results for 2Q 2019. The overall TV market declined quarter-on-quarter due to weakened consumption caused by unfavorable exchange rates in emerging markets. In terms of year-on-year growth, however, it is equivalent to that of last year, thanks to economic recoveries in developed markets. For Samsung, TV profits slightly decreased both year-on-year and quarter-on-quarter, caused by intensified price competition in the market. We improved product mix through early launches of new models and expanded sales portion of strategic products such as QLED TVs and super large screen products. In particular, the QLED TV has solidified its position as an industry-leading premium product in terms of both awareness and sales.
We will further strengthen our technology leadership with QLED 8K TVs launched in the first half. For the digital appliances market in the second quarter, demand in developed markets such as North America and Europe have been stagnant, but global demand slightly increased, backed by a steady growth of emerging markets like India. We expanded the sales of premium products and new models and had strong sales of WindFree air conditioner during the peak season. Our profits have also greatly increased year-on-year with the help of our main products such as refrigerators and washing machines. Now, I will share market prospects for the second half 2019. The TV market is expected to be equivalent to that of last year, despite risks such as unfavorable exchange rates in some emerging markets and increase of protective trade practices.
We will maximize on year-end peak season sales by cooperating closely with partners and will make a stable, high-profit structure by expanding the sale portion of high value-added products such as QLED TVs and super large screen products. We will solidify the message that Samsung is the leader in 8K by mainstreaming QLED 8K TVs in the market and take the lead in establishing the 8K ecosystem at an early stage. We will explore sales opportunities by strengthening the lineup of lifestyle products, which will add additional value to consumers' life. This way, Samsung will achieve high profitability and expand sales by continuously leading the premium TV market. For the digital appliance business, Samsung will focus on marketing and expanding sales of new products for our consumers' improved lifestyle, such as BESPOKE and AirDresser.
We maintain solid growth by continuously strengthening our B2B business, which includes built-in appliances and system air conditioners. Thank you.
Thank you. This completes our part of the presentation, and now we'll turn to questions and answer session.
[Non-English content] Now Q&A session will begin. Please press star one, that is star and one, if you have any questions. Questions will be taken according to the order you have pressed the number star one. For cancellation, please press star two. That is star and two on your phone. [Non-English content] The first questions will be presented by Mr. JJ Park from J.P. Morgan. Please go ahead, sir.
[Non-English content]
I have two questions. The first question is about the recent measures that are being announced by the Japanese government regarding the key components that are used for display and semiconductor industries. Does the company see any potential impact of this measure to the company's business? If so, how is the company preparing internally? Second question is tied to this. Actually, since this Japanese government plan was announced, there has been some increase in spot prices for both legacy and new products. There seems to be some restocking demand happening. Do you also see this restocking demand by your long-term contract customers? For example, are you getting some rush orders or your long-term contract customers seeking to get more volume?
[Non-English content]
To answer your first question from the IR team. Even though the recent measures by the Japanese government do not ban the export of materials, we are facing difficulties due to the burden of this new export approval process and the uncertainties that this new process would bring. The visibility is low. However, our executives and the relevant business divisions are dedicating their utmost efforts and deriving solutions to minimize any potential negative impact these new measures may have on our manufacturing process.
[Non-English content]
Regarding your second question, it is true that there has been observed some increase in the spot market prices recently. We read this as a combination of mainly two factors. One is actually a fundamental side, where there is seasonality kicking in with a strong second half. At the same time, we also read that there were some concerns of future supply stability due to the recent announcements. Given the fact that the recent increase in spot prices is actually a combination of various internal and external factors, I think at this point it is difficult for us to conclude whether this recent increase in spot market prices would have an effect on our long-term contracted prices.
[Non-English content]
[Non-English content] The next questions will be presented by Mr. Nicolas Gaudois from UBS. Please go ahead, sir.
Good morning. Thanks for taking my questions. The first one is on memory. You have considered earlier converting line 13 from DRAM to image CMOS sensors. As the DRAM down cycle continues for now, is this actually back on the agenda? If so, in which time frame would you execute the conversion? Similarly for the mobile business, you confirmed you're relaunching the Galaxy Fold very soon. What would be now your volume expectations for the Galaxy Fold in 2019? As you alluded earlier, you seem to expect to use foldable displays across several products. Can you confirm this is for 2020, and there to be two or more products? Could you give us a little bit more clarity on the Note 10 expectations this year, in particular your shipment forecast? Thank you.
[Non-English content]
[Non-English content]
To answer your first question. Currently, we don't have any decisions regarding the line 13 conversion to LSI. As we have always mentioned, basically our line operation strategy considers not only memory business but also system semiconductors. We try to find a strategy that would optimize our overall semiconductor line efficiency. Any future decisions would take into account comprehensively various factors, including the DRAM business cycle due to long term image sensor demand forecast as well as line efficiency.
[Non-English content]
To answer your question on the mobile side, the Galaxy Fold, which is an innovative product that adopts new technologies, new materials and displays. We are planning to supply that this year in limited countries in limited volume. However, the foldable category itself is something as a new form factor that we have been preparing for a very long time. Going forward, we will continue to expand the foldable lineup with various forms.
[Non-English content]
Regarding your question about the Galaxy Note10 new model that will be launched. The new Galaxy Note10 will even further upgrade the unique values of the Note series, especially it would feature an S Pen experience that is even more intuitive and is more rich and expanded. Some of the highlights of a Galaxy Note10 would be the more powerful performance, also more enhanced productivity related functions, and also an optimized multimedia experience for the 5G network. Even though it's early for us to present any specific volume targets, we are expecting the Galaxy Note10 to achieve higher volumes versus its predecessor, Note9.
[Non-English content]
[Non-English content] The next questions were presented by Mr. Peter Lee from Citigroup Global Markets Securities. Please go ahead, sir.
[Non-English content]
I have two questions regarding the semiconductor side. First, on the DRAM. Have there been any changes in terms of DRAM production since the last conference call? Second question on the NAND side. We've been hearing that the capacity on your line 12 has been decreasing. Can you share some details about that?
[Non-English content]
To answer your first question, actually, there hasn't been any changes in our DRAM production since the last call. We can say that as we have always, our line operation will be managed flexibly in response and depending on the demand changes. Currently we are not considering, for example, any artificial decrease of wafer input.
[Non-English content]
In the case of the second question about our NAND line 12 capacity, that's actually the decrease in our line 12 capacity is a reflection of how the demand is shifting for NAND from planar to V-NAND. There is a decrease in planar NAND demand, and that is why from the first half, we have been converting some planar capacity for R&D purposes.
[Non-English content]
[Non-English content] The next question will be presented by Mr. Do Hyun Woo from NH Investment & Securities. Please go ahead, sir.
[Non-English content]
I'll ask two questions. First question is about your DRAM and NAND inventory. Can you give us the inventory changes on a quarter-on-quarter basis? Also, can you share with us your second half outlook for your DRAM and NAND inventory? Second question is about the recent announcement of the licensing agreement for the GPU technology with AMD. Can you share with us, for example, what specific SOC models we can look forward to, when those models you plan to launch, and also the implications of this AMD relationship on your existing relationship with Arm?
[Non-English content]
To answer your first question about our inventory, first on the DRAM side, our second quarter DRAM inventory was flat. It was similar to the previous quarter levels. Given the fact that data center customers have resumed purchasing and also there has been a continuous trend of high density on the mobile side, the sales volume has increased and our inventory turnover has shortened versus first quarter. Looking forward to the second half DRAM inventory, we do expect there to be strong demand given the seasonality, and also we expect our inventory level to continue gradual decrease. In terms of the pace of our inventory decrease, given the very low visibility of increased expected industry volatility and external uncertainties, it's difficult for us to predict.
[Non-English content]
On the other hand, the case of the NAND inventory, given the fact that customers have realized that the prices have bottomed out, this has driven up demand. Also, sales towards the channels have also increased. NAND inventory has already started to significantly decrease, and we expect this to continue as strong demand comes up in the second half. We expect that in third quarter, for NAND inventory, we will be able to achieve balance levels.
[Non-English content]
To answer your second question about our AMD partnership, as you know, AMD has been a leader, especially in the GPU area since the early days of the PC market and is one of the leaders in terms of technology. We think that with this partnership, we will be able to leverage the GPU competitiveness of AMD to enhance the performance of not only our mobile SoCs, but also in other applications.
[Non-English content]
Considering the usual time it takes to vet out IT technology, we expect that the GPU technology will start being adopted in products that will be launched two years down the road, roughly.
[Non-English content]
Regarding the relationship that we have with Arm. Arm is an important strategic partner that we have, and that partnership will remain solid going forward.
[Non-English content]
[Non-English content] The next question will be presented by Mr. SK Kim from Daiwa Capital Markets . Please go ahead, sir.
[Non-English content]
I have two questions. The first question is about the DRAM. I think the market is still concerned that perhaps due to various uncertainties, the data center demand may stay weak for long term, or that in the second half, the mobile demand may become more uncertain. In that context, can you share with us the company's perspective on future demand from both server and mobile applications, as well as your outlook on second half demand and supply situation for DRAM? Second question is for the mobile side, actually regarding the 5G smartphones, there were some positive news that actually the Chinese handset makers may actually adopt or bring online 5G handsets earlier than expected. Given that context, can you give us the company's view on 5G demand as well as how the company plans to respond to the stronger 5G demand?
[Non-English content]
To answer your first question, about the DRAM demand. For the server side, as you know, the data center customers have been going through inventory adjustments starting from fourth quarter last year and continuing on to first quarter. Given that period, we think that a large part of their inventory has already been normalized. In fact, these customers have started to resume purchasing from late second quarter. Once the strong seasonality of the second half kicks in, we expect the demand to remain solid.
[Non-English content]
In the case of the mobile side, one major trend has been the high density trend across all smartphone products. Also, the price elasticity has been driving up demand for mobile DRAM as well. With the second half seasonality, we expect on the mobile side, demand will also continue to expand. From both server and mobile side, the basic fundamental demand remains strong and solid, and we expect that second half demand will increase versus first half.
[Non-English content]
However, given the increase in uncertainty in external environments, we do expect this may lead to more volatility in overall industry situation, and that's why we find it difficult to present any specific supply and demand forecasts.
[Non-English content]
Regarding your second question about our 5G strategy. For example, to give you an update on Korea, which started 5G commercial service last April, we have reached more than 1.8 million 5G service subscribers, and 5G service is actually growing faster than expected. In this growth, we have been showing very good, strong performance with our S10 5G model, and we are rolling that out to other countries such as Europe and Australia, as we did in Korea and the U.S. already. In the second half, we will also be expanding our 5G lineup with the Galaxy Note10 5G, and we will be preparing for the demand for 5G commercial service for each country depending on the country's 5G commercialization schedule.
[Non-English content]
According to Strategy Analytics, the 5G smartphones would account for about 42% of the entire smartphone market by year 2025. Given the initial pickup, which has been faster than expected, actually, the 5G smartphone market may expand faster than expected. Based on the early leadership that we have in our commercial experience and track record, as well as our technology, we will contribute to the rollout of 5G service and also at the same time solidify our leadership in the 5G market.
[Non-English content]
[Non-English content] The next question will be presented by Mr. Yoo Jong-woo from Hanguk Investment & Securities. Please go ahead, sir.
[Non-English content]
I have two questions. First question is about the foundry business. It seems that you've been signing up new customers for the foundry business. Can you share with us whether you have any plans of capacity expansions for 2019 or 2020? Second question is for the mobile side. Your margins for the second quarter was actually lower than expected. Going forward, given that you're probably expecting a larger volume or volume increase from your A series and also overall component prices are probably going to decrease, how much possibility do you see in terms of improved profitability or margins from your mobile business in the second half?
[Non-English content]
To answer your first question about the foundry, we're currently maintaining high utilization and we are planning to expand our capacity around EUV cutting nodes, image sensors and eight-inch technology where there is more demand growth that we're seeing. To give you some details, for example, we're planning to start operation of our Hwaseong EUV line from the first half of year 2020 and we'll be bringing that online in line with the seven nano technology development.
[Non-English content]
For the image sensors, the S4 line is the dedicated line for image sensors and we will continue to add on new capacity in line with the trends that we see on the device. For example, the multi-camera adoption on smartphones and also the greater demand for high pixel image sensors. For the eight-inch lines, we will continue to also add capacity there, especially around the PMICs and discrete power products.

To answer your second question about our mobile profitability. As you know, this year our focus has been on increasing our market share overall by strengthening the attractiveness of our overall lineup. As part of this process, we have been not only diversifying our flagship models, but also have been changing up our mass model lineup. In this process, our second quarter profitability has decreased mainly due to the need for building in more price competitiveness for our new mass segment models and also the inventory adjustment for our older models.
[Non-English content]
Now, in the second half, we'll be focusing on increasing our revenue, both on the premium as well as the mass lineup. For the premium model in the second half, we have the new premium models being launched based on our 5G as well as foldable new technology. Also in the mass lineups, we will be leveraging our product competitiveness and also our channel capacity to increase our sales globally. With such increase in revenue and also with greater operational efficiency, we will continue our efforts to improve our profitability.

I have two questions. I will give you the first question first before asking you the second one. The first question is on the NAND side. We are seeing NAND demand improving, recovering, also there may have been some supply side issues due to the recent power outage at the competitor. Can you share with us your views regarding supply as well as demand situation? Do you see a possible quick turnaround of the market situation during the second half?
[Non-English content]
In the case of NAND, I think it was mainly two factors. One is the price elasticity and also the fact that the customers have realized that the prices have started to bottom out. That's been driving a significant increase in demand starting from the second quarter. This has resulted in significant increase of our shipments for NAND in the second quarter and also a significant decrease in our inventory levels versus the first quarter.
[Non-English content]
Even though we can't comment on the supply situation of other suppliers, if we assume that the second half seasonality will kick in, and also if the suppliers, other suppliers, for example, go through their investment adjustments as they've been announcing in their conference calls, it is possible to expect stabilized prices and industry situation as overall industry inventory levels become normal starting from the third quarter.
[Non-English content]
At the same time, given the very high level of uncertainty in the external environment, there could be quite a lot of volatility in the demand and supply side, and that's why we will continue to very carefully monitor the market situation.
[Non-English content]
The second question is about the Memory CapEx for year 2020. Can you share with us your CapEx direction for next year? Also when you plan to operate the Xi'an and Pyeongtaek new Fab?
[Non-English content]
Regarding our next year CapEx plans, because the planning is not yet finalized, it's difficult for us to share with you the details. As always, we will be executing our investments efficiently in line with the market situation. Given the high level of uncertainty in the external environment, also the potential high volatility of the market, we believe that flexible CapEx is very critical at this point. That's why we have actually increased the frequency of reviewing our investment plan so that we're able to reflect any changes in market demand as quickly as possible.
[Non-English content]
Regarding our new fabs, they will be completed as scheduled. Existing schedule was to have Xi'an phase II completed by end of 2019 this year, and phase II of Pyeongtaek to be completed during 2020. Xi'an 2, we are planning to start operation of Xi'an 2 as scheduled, in early 2020 to respond to mid to long-term demand growth. Specific sizing of Xi'an and Pyeongtaek is still not yet decided, and we will be operating our investments flexibly considering the market situation.

[Non-English content] The next questions will be presented by Mr. Kim Dong Won from KB Securities. Please go ahead, sir.
[Non-English content]
I ask two questions. The first question is about the display side. There are talk in the market that the glass input feeding into your Asan number 8 line or 8th generation line has been discontinued. Can you share with us the company's position regarding this? Also, can you share with us your position regarding the conversion to QD-OLED on the display side? Second question is about the MICRO LED TVs. You've launched the 146 super large TV version, also there's expectations that you will bring this down to the consumer side, for example, a B2C consumer platform. I would assume that the price point would be a bit too high for consumers to approach.
In that context, can you share with us your plans of how to reduce the cost on the MICRO LED platform as well as your future product launching roadmap?
[Non-English content]
Regarding your first question about our display business, we believe that in the long term, there will be greater customer needs for higher quality display technology, given the expected increase in higher picture quality content and broadcasting that will be rolling out. That's why we believe that maintaining a technology leadership will be very important and critical in maintaining our overall business leadership. However, regarding the technology, no specific decisions have been reached yet. Regarding your first question about our line operation, we are operating our resources flexibly, depending on the market situation as well as our business strategy.
[Non-English content]
Regarding your second question about the MICRO LED TVs, as you know, it's one of the next generation display technologies that's gaining a lot of attention currently. The critical two issues in terms of technology is making the LED smaller and also securing the technology to go into mass production. These are the two key focuses in terms of the technology of MICRO LEDs. Given the strengths that we have, given our semiconductor background, we have already gained the industry-leading position in these areas. Currently our focus is on, as you mentioned, gaining the cost competitiveness or reducing the cost. Regarding our product lineup and future plans in terms of roadmap, as you know, in the first half, we've launched The Wall for the B2B segment.
Also in the second half, we're planning to launch The Wall Luxury, which addresses the B2C premium segment. We will continue this in this next year with, for example, more household or consumer applications, even branching out to the large size segment. Of course, the specific timing of these launches will take into account the market situation.

I think we have enough time to take two more questions before ending the call.
[Non-English content] The next questions will be presented by Mr. Mark Newman from Bernstein. Please go ahead, sir.
Hi. Thanks so much for taking my question. Two questions. First question, could you clarify some of the questions we've had in the past on memory capacity? You commented earlier that there's no artificial reduction in wafer input. Last quarter, you commented that there's going to be some line optimization for memory fabs, which would have some impact on wafer output, i.e. wafer output will be slightly down. I would like to ask specifically any update on that. If you could quantify how much wafer output will be different compared to the peak levels in Q4 last year, particularly for DRAM, also for NAND. The second question is on the memory demand visibility. A lot of positive comments on demand improvement. I'd like to ask specifically on data center. You commented data center DRAM demand improving due to low inventory.
Can we say that year-on-year gigabytes, are they going to be up in the second half versus last year? If you could quantify year-on-year data center DRAM, either market demand or Samsung demand, if you have any quantification around that, would be very useful to get an understanding of how much the DRAM demand is improving. Thank you.
[Non-English content]
[Non-English content]
To answer your first question, what we mentioned in the last conference call about our line optimization, that is basically relocating, repositioning our equipment in order to achieve greater line efficiency. On that side, there hasn't been any specific changes due to that. Our line operation policy, as you know, has always been to flexibly operate our lines in response to market demand changes. Once again, to clarify, at this point, we are not considering any artificial decrease in wafer input.
[Non-English content]
To answer your second question about the DRAM, specifically the data center demand. You've asked for specific quantified outlook on a quarterly as well as a second half versus last year second half comparison. Given the low visibility, it's difficult for us to share with you any details about the demand on a quantified basis outlook. We do expect that on a full year basis, in terms of content for DRAM, there will be about a 10% increase on a year-on-year basis.
[Non-English content]
Question before ending the call.
[Non-English content] The last questions will be presented by Mr. Mehdi Hosseini from SIG. Please go ahead, sir.
Yes, thank you for letting me ask a question. Two follow-ups. On the memory side, can you please provide the mix of DRAM technology today and by year end 2019 DRAM technology in terms of the 1Z mix? A follow-up on that, can you update us on when you would insert EUV lithography for DRAM application? One follow-up question on System LSI, if you could provide the mix of image sensor and how does a foundry compare to that? The mix of image sensors and foundry revenue would be great. Thank you.
[Non-English content]
Regarding your first question, I think we can answer that by sharing with you our outlook on our cutting node share that we're expecting at the end of the year. This will be 1X and above. We're expecting that to account for about 70% as of end of 2019. Regarding the 1Z, we can tell you that that development is coming along as we planned.
[Non-English content]
Regarding your second question of EUV adoption on our DRAM side, actually, our R&D center is going through evaluation of the equipment, and also we are trying to measure the productivity benefits versus the economics of using EUV for our 1Z process. I think there were some press releases in last March that hinted that we will go and develop 1Z without adopting EUV. Actually, to clarify, we're doing a two-track development for our 1Z. We're also at the same time considering a 1Z process that uses EUV. Sir, would you mind clarifying your third question about the System LSI business? You've asked for the share of image sensors and Foundry.
Yes. The mix of image sensor and foundry within a System LSI or within the overall semiconductor industry.
