August 5, 2025
Earnings Call Speaker Segments
Katsuhiko Yoshida
ExecutivesMy name is Yoshida. I would like to explain the consolidated financial results for the first quarter of the fiscal year ending March 2026. First, regarding numerical notation, figures were previously presented in units of millions or billions of yen starting from Q1 of the fiscal year ending March 2026. Figures will be presented in units of billions of yen to provide a clearer overview of financial performance. The further details on this change can be found in the disclaimer on Page 26. Consolidated net sales for the Q1 of FY March 2026 was up 3.2% year-on-year and down 2.1% quarter-on-quarter to total JPY 366.9 billion. Operating income down 7.8% year-on-year and down 19% quarter-on-quarter to total JPY 17.4 billion. Profit for the period attributable to owners of parent decreased by 17.2% year-on-year and decreased by 35.8% quarter-on-quarter to total JPY 10.9 billion. Both net sales and operating income exceeded the budget. Quarterly net sales hit a record high. Due to the appreciation of yen, there were negative FX impact. To be more specific, negative JPY 13.2 billion on net sales Q-on-Q and minus JPY 11.8 billion year-on-year. Operating income also saw a negative impact of JPY 1.8 billion quarter-on-quarter and JPY 4 billion year-on-year. This shows a quarterly trend in net sales, operating income and OP margin. The OP margin for the first quarter was 4.8%, down 0.5 percentage point year-on-year and down 0.9 percentage point quarter-on-quarter. This shows a difference between the forecast as of May and actual results for net sales and operating income by business segment for the first quarter. Net sales for PT exceeded expectations due to strong performance in data center application and robust sales for automotive bearings. MLS exceeded expectation, driven primarily by HDD motors and motor for automotive applications SE significantly exceeded expectations, mainly due to strong sales in mechanical components and semiconductors. AS exceeded expectations, especially in Access products and automotive devices. Operating income for PT exceeded expectations primarily due to the effect of increased sales. MLS was generally in line with expectations. SE significantly exceeded expectations, mainly due to strong performance in mechanical components and semiconductors. AS was above expectations. This slide shows the quarterly trend of Precision Technologies segment. Left graph shows quarterly sales trend and right bar graph shows operating income and line graph shows OP margin. First quarter net sales decreased 2.9% Q-on-Q to total JPY 64.8 billion. Sales of ball bearings were down 1.2% quarter-on-quarter to total JPY 43.6 billion. The monthly external shipment volume increased 11.3% Q-on-Q for an average of 265 million units, driven by strong growth in data center-related demand. External shipments volume hit a record high. Sales of broad end and fasteners totaling JPY 15 billion were down 8.3% over the previous quarter. Sales of PMC decreased 1% quarter-on-quarter to total JPY 6.2 billion. Operating income for the quarter totaled JPY 14 billion, and the operating margin was 21.5%. On a quarter-on-quarter basis, operating income remained nearly flat, while the operating margin improved by 0.5 percentage points. Looking at the results by product, we saw an increase in operating income for ball bearings. This slide shows the quarterly trend for motor, lighting and sensing segment. Net sales totaled JPY 105.1 billion, an increase of 3.8% Q-on-Q. By product, sales of motors amounted to JPY 80.2 billion, which was in line with the previous quarter, including resonant device. Devices due to the segment change. Sales of electronic devices, including smart products resulting from the segment change reached JPY 14.9 billion, an increase of 71.8% from the previous quarter. Sales of sensing devices totaled JPY 8.4 billion, down 9.3% Q-on-Q. Operating income came to JPY 5.1 billion with an operating margin of 4.8% quarter-on-quarter, operating income increased by 6.8% and operating margin rose by 0.1 percentage points. This slide shows the quarterly trends in Semiconductor and Electronics segment. Net sales totaled JPY 117.2 billion, which was a decrease of 3.6% compared to the previous quarter. This was mainly due to the decline in sales of optical devices and the impact of the segment change related to smart products despite sales increasing for mechanical components. Operating income came to JPY 2.3 billion, operating margin of 1.9%. Compared to the previous quarter, operating income decreased by 30.1% with operating margin falling by 0.7 percentage points. This slide shows the quarterly trends for the Access Solutions segment. Net sales came to JPY 78.9 billion, decreasing by 6.5% compared to the previous quarter. Operating income came to JPY 2.7 billion with operating margin of 3.4%. Compared to the previous quarter, operating income decreased by 48.1% with operating margin falling by 2.8 percentage points. The bar graph here shows the transitions in profit attributable to owners of parent and the line graph shows the changes in earnings per share on a quarterly basis. The profit for the quarter was JPY 10.9 billion, and earnings per share was JPY 27.1. Next is about the changes in inventory on a quarterly basis. At the end of the first quarter, inventories came to JPY 370.8 billion, which was an increase of JPY 19.9 billion compared to 3 months ago. This was mainly due to the strategic buildup of inventories needed for the expected increase in sales from the second quarter onwards. On this slide, the bar graph is showing the transition in net interest-bearing debt, which is total interest-bearing debt minus cash and cash equivalents and the line graph showing free cash flows. At the end of the first quarter, net interest-bearing debt came to JPY 252.7 billion, increasing by JPY 11.3 billion compared to the end of March 2025. Regarding free cash flows for the fiscal year ending March 2026, we currently have not factored in any M&A-related expenditures. The risk scenario for the fiscal year ending March 2026 initially announced in May has been revised and the base scenario remains unchanged. The exchange rate assumption is JPY 140 to the dollar. This slide shows the forecast by business segment using the base scenario. And this slide shows the forecast by business segment using the risk scenario. This is all for my presentation.
Unknown Executive
ExecutivesNext, over to Mr. Kainuma.
Yoshihisa Kainuma
ExecutivesSo I would like to talk about important points for today's briefing. I would like you to read what is written on this slide. So Q1 finished better than our expectation. So reciprocal tariff in actuality did not have a major impact on our business. Having said that, however, as you may be aware, 15% tariff on automotive, we don't know when it will begin. And employment statistics, according to what I hear, there seem to be many differences. So there is a range to the projections. And at the end of Q1, I think it will be risky to fix the projection at this point in time. But the minimum level has risen to some extent. That is how I would like you to understand. In November, when we announced our earnings in November, I should be able to share with you more solid numbers. Having said that, however, for some reasons, we are enjoying good performance. And more recently, July, August and September, this momentum is likely to continue. The only problem or a burden on businesses, subcore businesses. I will come back to this point later on. On the other hand, Thailand and Cambodia conflict in that region has been reported by media. Both countries have agreed to cease fire and the actual impact is quite negligible. On a monthly basis, 50 million to 60 million additional cost has incurred. However, when the conflict intensified, I was visiting Thailand and Cambodia. So the separation of politics and economy the high-ranking officials of the government of both countries seem to agree on that. And therefore, I, myself, am confident that logistics or the flow of goods will be resumed in the near future. The next topic is the reciprocal tariff. As you can see here, what we make in the U.S. and the sell in the U.S. amount to JPY 160 billion and only JPY 40 billion we export to the U.S. and JPY 180 billion shown underneath that is the amount of transaction we make outside the U.S. And our products coming into the U.S. in the form of finished products amounts to JPY 180 billion. And top right and bottom right do not matter. So only JPY 40 billion is the amount that matters. And 80% of the customers, we have been able to pass on the additional cost to them surcharge system. So USD 1.34 million was the additional cost incurred in Q1 on a quarterly basis, if the current situation prolongs, the amount may increase going forward, but we are negotiating with remaining customers, and our policy is to pass on the additional cost 100% to the customers. So it may take more time. But when things become clearer, I would like to report to you. Next page, please. As you can see here, I mean actually compared with Q1 of the previous year, about the profit, subcore businesses, in other words, the game consoles and the OIS. -- so down JPY 3.1 billion. I will give you more details later on. If this had remained flat, it would have been the record high Q1 profit. So core business, I feel safe in saying the core businesses achieved a record high performance. In November, our growth drivers, for example, the rider, which is fully automotive driving and drone and humanoids, so these are 3, I will be able to share with you future projections, and it seems quite promising. Humanoid at CES to be held in January, our humanoid products or our products for humanoid will be exhibited at the CES to be held in January. And what we are working right now, the hand for humanoids, so our products are differentiated from our competitors' products and such hands will also be exhibited. And our core business is likely to further expand going forward. Moving on to the next page. The bearings are enjoying excellent business. Production hit a record high and the monthly plan, 24 million units has been exceeded. And in the second half of the year, so 340 million units per month, which is a record high monthly production, we are aiming to achieve. And the people working in the field are highly motivated and order intake is quite good. So the bearings and firm motors for data centers and automotive bearings are doing well as well. And P-PODs are also doing well and PMC or machined components are doing extremely well. The only thing that is lagging behind in production is road end and CNA, the medical, is at a low level and FX is moving in the negative direction. But right now, we are enjoying excellent performance. So our profitability is improving. Next page, please. So this is something you may be already familiar with fan motors, cooling system for data centers. Even though the method changes, the demand for motors is quite solid. So our high-performance bearings, there is still good room for further expansion. So that was about bearings. Next page, please. The motor lighting and sensing. The motors are doing extremely well as well. Fan motors will enjoy high margin this year. Even if we may -- even if we do not renew the record, something very close to that can be achieved. And HDD is really solid as well. high additional value products are being produced and backlight has finally hit the bottom. And tablet, the volume is expected to grow going forward. So we'll be able to contribute to our profitability. And automotive, in my opinion, innovative display will be launched and the mass production has started. I mean full-fledged mass production will begin next year, but the backlight has definitely hit the bottom. As for the smart products, battery protection module that is also performing very strongly. forecast for the next fiscal year in detail will be explained come November. But without question, this will become a strong profit driver next fiscal year. So that's the kind of segment that this is starting to turn into. Next is regarding SE. So the first page is concerning semiconductors. And the power device price correction is making a steady progress, though it is somewhat gradual, but profitability has been recovering. And we did have some issues at the front line for power device, but that has already been corrected and has not led to being a major issue. So the former, the OMRON Group, the Shiga plant, so the MEMS making or the noncontact the temperature sensors, they are likely to contribute towards profitability going forward. And semiconductor, some which is struggling very much if you look elsewhere. But despite the strong headwind in various areas, we are continuing to maintain high profitability. That is because we are focusing on the niche market, and we are able to really strongly appeal our strength. And that has enabled us to achieve these results. And the next page, this is the subcore and something that we need to explain today. If you look at the bar graph on the right, the first quarter last year was JPY 18.9 billion. And so you have a slight amount of some core profit and operating income on top. But if you look at the first quarter, you can see that the contribution is negative. So this negative the range. And if you compare that to the profit contribution in the first quarter last year, that's about JPY 3.1 billion if you add the 2. And why did we perform poorly was because for the optical, the device, we had the rare earth issue where the capacity utilization in our factory came down quite significantly. And -- so the export, the approval from China for rare earth did not come all that easily. And so we have been collaborating with customers. And so not from China, but in Vietnam. So we have been the molding the components in Vietnam and bringing that in. So that's the kind of thing that we are doing right now or becoming rare earth less, in other words, not using rare earth. So we have been producing samples of that type of product to customers right now and just waiting for approval by the customers for such a product. But from June, we have been able to resume production, but there is still that the uncertainty in regards to the part supply it's somewhat volatile. So this is likely to see a bit of pushback. But the full year, the sales number has not changed. The customers have not changed. And so from our perspective, after August, we want to certainly catch up. So that is where we are. But if for now, so more than 80% or so, we have come back, but not quite back to 100% as yet. And next week, I will be visiting the local operation, and I intend to check up on the situation. So that's the situation regarding optical devices right now. It will take some more time, but it's a matter of time. The productivity or the production front line, they have already implemented countermeasures. So as long as we are able to source the components, we shouldn't see much issue. For mechanical components, -- so from ICU -- so we have made a release on that. So being less than JPY 150. And so the parts that we procured when the yen was weak and because of the appreciation of the yen, we have ended up incurring loss associated with currency translation. And so from the second quarter onwards, we should be able to overcome this issue and generate income or the profit as we have planned. That's the plan for now. The first quarter, the level of contribution was quite low. But July, August and September, if the exchange rate remains stable, then we shouldn't be impacted significantly and should be able to generate a profit as scheduled. So we have been able to confirm to that level. As for the Access Solutions, we saw a wonderful productivity improvement. So whether it be paying for the critical processes, the improvement in the productivity that has gone really well. And so the profit, the contribution is biased towards the second half of the year. But from our perspective, something that we have been doing for a number of years. So the high-margin products. And so designing for the automotive until launch, often it takes 2 or 3 years, it's time consuming, but they are starting to launch the market and that will translate to volume. And this year, we had various issues, say, for example, the reciprocal tariff for the China issue. But for now, we should be able to generate profit as expected. But European players because of the slower car sales in China, that has caused a bit more of a struggle for the European players. But from our perspective, we've seen the productivity improvement and launching products with a higher margin. And through these measures, we intend to overcome the situation. [ Subaki Nakashima, ] there's been various things. But as you can see on the slide, we intend to do this business. This is more -- this is for humanoid. So smaller high precision, so the double way or the positioning that will become necessary going forward. And so strength, we should be able to leverage our strength for this type of component. And so in that regard, quality issue did occur for Tsubaki Nakashima but so the outcome has all been cleared with the customers and have been able to confirm that we didn't cause the practical issues. And as a consequence, we'll be undergoing this type of procedure. And the second point is we have divested in the U.K.'s subsidiary of the Honda Ashinkoyo. It's a small company, but not much point for us to keep the company. So we decided to sell this company. Page 25 is regarding dividends. Last year, we paid JPY 20 at the interim period. But this year, we have decided to pay JPY 25. So the payout ratio improving from 20% to around 30%. And this was a change in our policy. And so if everything goes the same for the end of the year, we should be able to also pay about the same amount, leading to increase in dividend amount for the full year. But there are still some areas where things are not transparent at this point in time. So on this occasion, we decided only to explain the interim dividend amount. That is all for me.
Operator
OperatorNext, we would like to have questions and answers session. The first question is from Mr. Takayama of Goldman Sachs.
Daiki Takayama
AnalystsI have 2 questions. First, on Page 17, I have to read this slide. So SE risk scenario at SE, Q2 seems to be higher. So rather than the risk, is this a realistic profit projection? And the PT seems to go down in Q2, but is it actually higher than this? So more realistic profit level of these 4 segments, I would like to understand there may be ups and downs. So my question is about the profit level in Q2.
Katsuhiko Yoshida
ExecutivesFirst of all, these numbers were put together rather automatically or the first half. So it's a first half forecast minus Q1 results. And as you pointed out, these numbers may not be totally realistic in some cases. So how they would be by segment, roughly speaking, in Q1, the published number, JPY 14 billion and JPY 17.3 billion, so JPY 3.4 billion up. So it may be compensated in Q2, which is not really right. But inclusive of that, PT, the numbers shown here, the base scenario based on base scenario, I mean, risk scenario are quite similar, but please refer to base scenario numbers. So JPY 13.5 billion, in actuality, Q1 was JPY 13.9 billion, so JPY 14 billion. So in Q2, it will be higher than JPY 14 billion. And the reason is, as Kainuma explained previously, bearings are doing extremely well. So rod end, the medical applications or the -- some European production sites have negative factors, but PD as a whole is doing quite well. So the numbers should be higher than this. And MLS, these numbers per se, JPY 6.9 billion profit in Q2, and this number will be somewhat better than this. And the reason for that is motors and sensing devices as well as backlights are basically improving Q-on-Q. So that is the main reason. And within SE, there are some ups and downs. PT and MLS in that sense, the numbers may be a bit conservative, but SE, for some items, the numbers may be conservative. And for some others, it's not conservative. For example, optical devices, it's not conservative. The first half overall, OIS production may go down a little bit. So that is a negative factor. However, as Kainuma explained earlier, more recently, rare earth issues are likely to be solved. So in August onwards, inclusive of Q3, the full year numbers should remain more or less the same. Coming back to Q2, semiconductors and mechanical components are likely to have upside. So the total numbers in net, the total numbers are likely to be better than the ones shown here. AS virtually the same as these numbers. So overall picture, I would like you to understand in that way. I see.
Daiki Takayama
AnalystsUnderstood very well. My second question is Mr. Kainuma talked about expectations for 3 items: Drone, humanoid and what was the other one? And humanoids, Mr. Kainuma commented several times, like JPY 30 billion in 2030. And Mr. Kainuma I think he was not completely sure about that. But now it's clearer. Am I writing assuming that way. So what are the changes you have experienced?
Katsuhiko Yoshida
ExecutivesSo the 3 items, riders for autonomous driving, camera, riders. So there are 3 methods. San Francisco, the Waymo running in San Francisco and Amazon-related autonomously driven cars have riders. Of course, cameras are also installed, but the riders detect the obstacles and our PMC, the mechanical components, bearings and many others are used. And if that method becomes the mainstay or the mainstream, we will be able to see huge business opportunities. But what's been talked about, Tesla will use cameras. The current Tesla models too. So whether the humans attach steering wheels, I mean, if it is completely autonomous, the human drivers will not be behind the wheel, but it's going to be quite interesting. Humanoids, So SES, we are serious about exhibiting our products at SES in order to see people's reactions, motors, sensors, we have received many inquiries, so 8 spears, all of 8 spears, it's like we are getting all of 8 spears. But the issue is 1.4 million units in 2030, we are speaking about. So simple addition will be 3 million units. But the humanoids, I mean, I'm not sure whether the number of humanoids will reach that kind of number, but many start-ups are already working on this. Regarding bearings, to a certain start-up, we supply 170 units of bearings to one humanoid. So it's like an aggregate of bearings, not only bearings, small-sized motors and sensors, the various things. So I would like to share with you more details in November. But today, I wanted to give you a heads up.
Daiki Takayama
AnalystsNow a follow-up question. So looking back, I think you have received many questions from investors about the business portfolio and how to increase top line, et cetera. But 8 spears plus or comprehensive approach has it become clearer sharpened up and profit margin is another factor. So how you are sharpening your vision?
Katsuhiko Yoshida
ExecutivesSo what we aimed at. So ultraprecision is the source of our strength. So robotics, it's not that we want to handle all kinds of robots, but the robots with ultraprecise movements, we would like to use our products in them. So humanized, 1.4 million units it's not that all of them will use our products. But one way or another, things will accelerate. So what we have, we will be presenting a lot of samples in order to judge what people will become interested. But the sensors, the pressure sensors we have and we have received many inquiries and shipped many samples. And if this becomes a smashing hit, then we can put it on mechanical components and supply it to our customers. in a combined manner, starting with DVD and smaller-sized laptop computers and smartphones. So in the new era, new things launched. But now the 3 of them have come out altogether.
Operator
OperatorI'd like to proceed to the next question from Morgan Stanley MUFG Securities. Shoji Sato.
Shoji Sato
AnalystsThis is Sato from Morgan Stanley Securities. First question is about the numbers for bearing the sales volume. I understand that there will be an increase in the second quarter as well. But for the third quarter and the second quarter, the monthly, the sales volume, both internal and external. And for the second half of the year, so 340 million production is what you're expecting, which is record. So when do you intend to increase the production? And what is the current production capacity right now? So this is the first question, please. So based on the actual, so starting with April is okay?
Katsuhiko Yoshida
ExecutivesSo external ship volume, shipment volume 253, 266, 276, that's for April, May and June. And for internal sales, actuals were 47, 47 and 49. And after July, 276, 272, 279. The internal sales, 46, 52, 52. And on the production side from April, 283, 300, 308, 333 for July, 335 and 321. So October onwards, when we have many operating days, we will exceed 340. And that was what Kainuma-san was talking about in terms of realizing a record high. And for the capacity, as we have been explaining from the past, about 400 million units. It does depend on the product mix as well, but that is what we are able to do. And so even if we produce 340 million, we still have some spare capacity.
Shoji Sato
AnalystsMy second question is the optical device in the first quarter. You explained that it was quite tough. But what -- is there any changes to the full year forecast? And so in the second and third quarter, how do you intend to see that pick up in terms of the curve?
Katsuhiko Yoshida
ExecutivesWell, in terms of sales, the first quarter was very low start. It's difficult to refer to a specific number, but about CNY 20 million. And second quarter was upwards of CNY 60 billion. And in the third quarter, probably similar types of number. And in the fourth quarter, will come down again. So that's the kind of transition that we are expecting as far as numbers are concerned. So just to confirm, for the full year, the forecast remains unchanged. No, it doesn't -- it remains unchanged. So the -- there is some -- the changes in numbers in terms of second and third quarters. But added to that, as we have explained before, the numbers we have explained as a part of the guidance. So we are subtracting the first quarter number from the first half number. So if you could make some adjustment in that regard as you put together the model. So from August onwards, the production has normalized. Is that right? Well, the production itself, as Mr. Kainumo has explained, has normalized. And it's essentially whether we are able to source the materials or not. That's just the point. So what will happen in terms of sourcing the raw materials, I think, will potentially change the situation. It's really up to them.
Operator
Operator[Operator Instructions] Let us move on to the next question. Mizuho Securities, Mr. Goto.
Fumihide Goto
AnalystsSo this is Goto from Mizuho Securities. I have 2 questions. One is about external sales projection of bearings. Recently, the past record has been exceeded. And by application, there are some differences in level. that is coming back and automotive structural increase, how possible that is. And the segments that have not made a complete come back may come back going forward. So the possibility of such improvement, should I assume, what is your thought on that?
Katsuhiko Yoshida
ExecutivesFirst of all, the recent situation, as you rightly pointed out, the data center-related quite robust. China and external sales. So this trend is likely to continue. On the other hand, automotive, depending on the OEM, the situation may be different. But inclusive of content growth, things are growing. And if the production volume remains the same, 5% to 7% or 8%, the automotive -- the bearings for automotive applications will grow. So we maintain the same forecast. And this trend will probably continue next year onwards and fan motors, as Kainuma explained, CAGR, 17% CAGR can be expected, 18% or 17.8%. So in '27 or '28, big growth can be expected. However, the cooling system, so innovations are happening on a daily basis. So whether this will remain the same for some time, I don't know, but it's going to be even more high performance. And as autonomous driving spreads, the additional devices will become necessary. Likewise, 5% to 8% CAGR is likely. So we maintain such forecast. In addition, as for the major changes in recent time, drones and robotics, so growth related to those, there seems to be high potential. So drones, more than 30% CAGR is likely to be actualized. So that is my answer for your question. About robotics, so some use 170 units of our products or other robots may be simpler. And some may be quite similar to human bodies. So we are now scrutinizing how we can capture business opportunities. And at this point in time, it's rather difficult to quantify the business opportunities.
Shoji Sato
AnalystsUnderstood. My second question is about smart products, DBU, the demand is growing, I understand. And AI servers, data center servers, the power consumption is increasing. And therefore, business opportunities are likely to grow going forward. So what is your take on this?
Katsuhiko Yoshida
ExecutivesYes. As you are aware, every quarter, so we are making revision like particularly power storage related or the battery-related customers are enjoying a good business, and we need to secure production capacity in order to follow up their demand. So we need to implement a broad range of measures. About the future, the battery protective module, in addition to that, there are various peripheral businesses. As Kainuma mentioned, there are many business opportunities that we can seize regarding that, Well, in November, we will be able to share more information with you. So the customer base is customer base expanding? Yes. As you may be aware, we have one very strong customer as a core customer. In addition to that one, the automotive and we will be expanding our product lineup in order to increase our business.
Operator
OperatorSo I would like to proceed to the next question from UBS Securities, Hirata-san.
Shingo Hirata
AnalystsThis is Hirata from the Securities. Thank you for the please go ahead. I have 2 questions. The first question is regarding SE and the third quarter, you actually exceeded by JPY 2.7 billion, and that was the semiconductors, the mechanical components. But can you give the quantitative breakdown? In terms of semiconductors, there was a kind of a rush demand prior to the tariff increase, I believe. And from the second quarter onwards, you said it's going to be strong. But could you give more details in terms of the field of the application and also the upside for the mechanical components, and it depends on the customers of the product, but how can you -- how should I think of in terms of the upside?
Katsuhiko Yoshida
ExecutivesWell, first of all, in terms of mechanical components, how much upside is there? Well, it's not included here. So we are looking at it quite conservatively right now. And in that regard, if the mechanical component customer ends up making upward revision to production. And if we are able to capture that business opportunity, then there should be some upside that can be expected. And in terms of -- sorry, in terms of semiconductors, as to whether there is brought forward demand or not, well, our product is such that it is more niche top customer type of product. So we're not expecting anything significant in that regard. But from the first quarter, we have continued to receive quite strong numbers. So that's the situation for semiconductors. And for BB as well, we have the analog and power, the situation being different from the 2 for that analog, the numbers are quite strong, 1.2, for example, is where we are seeing right now. And for the optical devices, as against the expectations, it was weaker. And so you have to do the math to come up with the numbers.
Shingo Hirata
AnalystsIn the first quarter, semiconductors and the mechanical components upside, but it was more the upside from the semiconductor was more significant. Are you talking in terms of profit?
Katsuhiko Yoshida
ExecutivesWell, in terms of profit, yes, the semiconductors were very strong.
Shingo Hirata
AnalystsAnd in terms of application, the strong application was related to smartphones. Could you give some information in that regard?
Katsuhiko Yoshida
ExecutivesSmartphones were strong. And we received strong inquiries outside North America as well. And so mobile, I think in general, we are receiving strong business. And for power devices as well, it was quite good in the third quarter as well. And IGBT, for example, well, rather than IGBT, the other type of the power semiconductors, say for example, the air conditioning application, they were quite strong. And even in IGBT, so we also do the trains, electrical railway. So we have received strong inquiries there as well, which has showed strong numbers, too.
Shingo Hirata
AnalystsMy second question is again for SE segment. So I understand that you struggled in the first quarter and the second quarter, so July is looking somewhat tougher. So unless the export from China is resumed, the situation will remain difficult or -- but -- or do you have expectation for supply to increase rapidly from areas outside China? And if you are to procure from outside China, would there be additional cost incurred? Or are there anything that could potentially be a risk?
Katsuhiko Yoshida
ExecutivesWell, in terms of additional cost, not in terms of the unit price of the product to be procured, there is an approval and the management process required. So there are some costs incurred on a onetime basis, but this can be resolved. And overall, it's negligible. And what we are trying to do is, of course, to moving away from China. And DY, the most important metal and so not to use that becoming a DYless. And if we're able to do that, so we no longer have to use the restricted product. And so hopefully, we are able to resolve this issue from such a perspective. So as far as the course of direction is concerned, not just ex China, but we have multiple plans through which we are trying to resolve the situation. So that's where we are right now.
Operator
OperatorBecause the time is limited, the next question will be the last one, Nomura Securities. Mr. Akizuki.
Manabu Akizuki
AnalystsSo Akizuki from Nomura. Briefly, I would like to confirm the numbers. First, MLS on year-on-year, the profit margin last year was 5.2% and this year is down to 4.8%. But HDD did very well. So I thought it would be higher than this. But the profit margin, what is the reason why profit margin declined year-on-year? If you could explain, please?
Katsuhiko Yoshida
ExecutivesHDD, the customers' numbers and our numbers, because of supply chain inventory adjustment, there is a difference. And from our customers' financial results, we assumed our numbers and our numbers seem a bit weak. And our share is not 100%, but inventory adjustment comes in between the 2, and there is a lag, time lag. And as for Q1 numbers, Akizuki-san, your assumption for Q1, probably our assumption was somewhat weaker. But as was explained at the outset, it did better than the assumption or expectations. And the same applies to full year expectations. For HDD, we took a conservative view. So 10% year-on-year, 10% decline year-on-year for motors as a whole, that is our assumption. And Q1, there was inventory adjustment. So looking at the situation from customers' numbers, it was rather weak.
Manabu Akizuki
AnalystsMy second question is PT is very strong. And by application, you explained the numbers. So I understand the overall situation, but if it is possible, can you explain the bearings or by application, the breakdown year-on-year.
Katsuhiko Yoshida
ExecutivesThen I would like to explain that. Q1, Q-on-Q, the breakdown, automotive, 19% and space and aircraft, 39% and home appliances, 39% and OA 3%; and PC and peripherals, 2%; motors, 18%; Amusement, 1% Others, 16%. Q-on-Q growth rate. Well, year-on-year, if possible, please, year-on-year. Automotive, minus 9%; Space and aircraft, plus 11%; home appliances, minus 12%; OA, minus 12%; PC and peripherals, minus 10%. Motors, plus 26%; Amusement, minus 4%; others, minus 10%. I see. The motors, data center and air conditioners, it's included in.
Manabu Akizuki
AnalystsSo should I take it as a motors in general?
Katsuhiko Yoshida
ExecutivesYes, exactly. I see.
