Good morning. My name is Chris and I will be your conference operator today. At this time, I would like to welcome everyone to the Rogers Corporation 2016 Third Quarter Conference Call. All lines have been placed on mute to prevent any background noise. After the speakers' remarks, there will be a question-and-answer session. [Operator Instructions] Thank you. Bill Tryon, Director of Investor and Public Relations, you may begin your conference.

Bill Tryon

Analyst

Thank you, Chris. Good morning, everyone, and welcome to the Rogers Corporation 2016 third quarter earnings call. The slides for today's call can be found on the Investor section of our Web site along with the news release that was issued yesterday. Please turn to Slide 2. With me today is Bruce Hoechner, President and CEO; Janice Stipp, Vice President, Finance and CFO; and Bob Daigle, Senior Vice President and CTO. Turning to Slide 3. Before we begin, I would like to advice that statements in this conference call that are not strictly historical are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 and should be considered as subject to the many uncertainties that exists in Rogers' operations and environment. These uncertainties include economic conditions, market demand, and competitive factors. Such factors could cause actual results to differ materially from those in any forward-looking statement. Also the discussions during this conference call may include certain financial measures that were not prepared in accordance with Generally Accepted Accounting Principles. Reconciliation of those non-GAAP financial measures to the most directly comparable GAAP financial measures can be found in the slide deck for today's call, which is posted on the Investors section of our Web site. I will now turn the call over to Bruce.

Bruce Hoechner

Analyst

Thanks Bill. Good morning everyone and thank you for joining us for today's call. Before we get to the slide deck, I want to let everyone know that Bill has decided to retire at the end of this year. Many of you speak with Bill regularly and are well aware of his acumen with Rogers financials and our overall business as well as his understanding of the markets and what is important to our investors. Thank you, Bill for all you've done for Rogers. Please join me in wishing Bill the best as he leaves Rogers to enjoy his retirement. Now, please turn to Slide 4, in Q3 2016, Rogers achieved net sales of $165.3 million exceeding our previously announced guidance. This is an increase of 3.1% over Q3 2015, which included $5.2 million of revenue from the divested polyimide and thermoset laminate business excluding the effect of the divested assets, Rogers net sales increased 6.3% over Q3 2015. Performance during the quarter was driven by strong gains in EMS and PES business segments, while sales and ACS decreased slightly. Third quarter operating margin decreased 50 basis points to 14%. Our continuing efficiency initiatives were offset by higher SG&A spend related to strategic activities and incentive compensation accruals. Gross margin which is not reflected in the slide was 37.5% an increase of 30 basis points over Q3 2015. This performance reflects our ongoing commitment to operational improvements. Q3 adjusted EPS was $0.95 exceeding guidance and $0.21 above the mid-point of the range. Adjusted EBITDA was $34.1 million or 20.6% of net sales for the quarter. During the quarter, we experienced continued demand for e-Mobility applications as well as positive growth in general industrial, clean energy and portable electronics. In general, we are pleased with the trends in a number of…

Janice Stipp

Analyst

Thank you, Bruce, and good morning everyone. Overall, we were encouraged with our Q3 2016 financial results despite difficult conditions in some of the markets we participate in. As you will see in our numbers, we continued to gain momentum on our performance initiatives. Adjusted earnings per share of $0.95 was above our current guidance estimate. Q3 2016 revenue of $165.3 million exceeded guidance level in Q3 2015. The increase over last year was primarily a result of strong EMS and PES volumes partially offset by the non-core asset divestiture. Improved gross margin of 37.5% up 30 basis points was compared with Q3 2015 as a result of increased demand, set of operational performance and improved margin profile associated with the non-core asset divestiture just noted. Continued strong cash generation ending the quarter with cash of $173.5 million on the balance sheet and $94.2 million of cash provided by operating activities for the nine months ended September 30, 2016. Net income at $16.1 million, was approximately 28% higher than Q3 2015. Now, if you turn to Slide 11, I'll review our third quarter results in more detail followed by our fourth quarter guidance forecast. Q3 2016 revenue, as previously noted, was a $165.3 million, which exceeded guidance in Q3 2015 primarily a result of increased volumes in EMS and PES businesses partially offset by the Q4 2015 non-core asset divestiture. Adjusted operating margin was down 140 basis points from 16.6% in Q3 2015 to 15.2% in Q3 2016 primarily from higher SG&A Q2 2016 strategic business investments as well as $3.6 million year-over-year increase in incentive compensation resulting from the current year accrual combined with the reversal of Q3 2015 accrual. Adjusted EBITDA of $34.1 million improved $1.6 million or approximately 4.9% compared to the third quarter of 2015, as…

Bruce Hoechner

Analyst

Thank you, Janice. Before we move to Q&A, I would like to highlight some of today's comments. We believe Rogers is uniquely positioned to benefit from many significant market driven growth opportunities, the rapid adoption of Advanced Driver Assistance Systems or ADAS and the fast emerging technologies of 4.5G and 5G in the telecom space. We will continue to bolster advance connectivity solutions business performance. The growth in our power electronic solutions business is driven by our ability to provide enabling technologies that address the challenges of eMobility from X-by-Wire to EV/HEV applications as well as technologies for energy saving motor control systems. And our Elastomeric Material Solutions business is growing again as we demonstrate the advantages of our polymer technologies and providing ceiling and cushioning solutions for eMobility, general industrial and portable electronics applications. This concludes our prepared remarks. And we will now open the line for Q&A. Chris?

Operator

Operator

Thank you. [Operator Instructions] And our first question is from Dan Moore with CJS Securities. Your line is open.

Unidentified Analyst

Analyst

Good morning. Thanks. It's actually Chris for Dan. Maybe could we just start with the ACS operating income and margins, obviously, down year-over-year, can you talk a little bit more about the specifics and then from there kind of how that translates looking forward?

Janice Stipp

Analyst

Yes. So that we kind of set the parameters really on ACS, although it decreased that you see on operating profit. When we take out the adjustment for Ireland because they have allocated a higher portion of the corporate allocations because they have the assets. And we adjust for the SG&A which they -- the corporate SG&A for our business -- strategic business initiative. Really the margin only deteriorates a few points just over 17%. So when you see the decline, it's not quite as drastic as you see on there, when you adjust and normalize the two numbers.

Unidentified Analyst

Analyst

Got you. You had mentioned within there, there was some price considerations offered, can you talk a little bit more specific on the pricing side?

Janice Stipp

Analyst

Yes. The pricing side, just about $1 million for really one of our strategic customers that they gave us committed volume was just significant and so that we thought with the contribution margin differential on the volume, it was actually advantageous for the -- for us to actually get the price down and get that guaranteed volume.

Unidentified Analyst

Analyst

Got you. And then specific to on the wireless side, you talked to us a little bit, but can you talk about kind of expectations for growth Q4 and moving into 2017?

Bruce Hoechner

Analyst

Right. And as I mentioned Chris in the prepared statements, we had seen we were affected by the auction -- the delay in the auction of the spectrum in India. We now see that that's been completed -- we now see that coming into focus. So we think we will see some gains from that as we move through the rest of the year. As we look ahead into 2017, the buildup of or the movement to 4.5G is something that we are starting to see and actually even design wins that are focused on 5G. I'm going to ask Bob Daigle, our CTO to expand a little bit more on what we see going forward in the technology space here.

Bob Daigle

Analyst

So Chris, I think a couple of points to add to what Bruce mentioned. I think on the 4.5G front, I think we are very encouraged by -- you may recall when the transition from 3G to 4G occurred. That was advanced 3G but it really didn't involve any infrastructure, it was just an upgrade to software. And what we have been able to determine with 4G upgrade as you go to massive MIMO in the -- what's being called advanced [indiscernible] standard that requires new hardware. Though we are expecting to see some nice demand for the transceivers as you start to build out the networks for what people are referring to as 4.5G. The other thing that's really interesting and favorable dynamic is what you are reading and hearing about in terms of the early stages of 5G. Because most of the press out there -- the truth 5G handhelds are really -- you are talking probably 2019/2020 before you see a mass rollout. But, what a lot of the carriers are focused on right now is deploying what's being referred to as 5G for fixed point -- what's called fixed point wireless. And then, in simple terms what they are basically saying is you got enough capability enough to handle this with 5G to support television streaming. So you could picture a lot of regions of the U.S., you really don't have competitive situations between the cable guys providing television service tend to be monopoly. And a lot of what you are reading about right now for early stages of 5G is really technology that allows the wireless guys to play in the television world and to us that's an encouraging -- that's very encouraging, it's a new application area that tends to prove out the technology for 5G early on without having to basically hand-off calls from cell site to cell site because it's fixed point, but it creates some early momentum, which we are encouraged by.

The next question is from Sean Hannan with Needham & Company. Your line is open.

Sean Hannan

Analyst

Yes. Good morning folks. Thanks for taking my questions. Can you hear me?

Bruce Hoechner

Analyst

Yes, Sean.

Sean Hannan

Analyst

Okay, great. Just want to circle back from that pricing topic, just want to make sure that we are in a scenario where some of these types of concessions and agreements in more secure kind of a firm revenue stream that we are avoiding going down a slippery slope here, you can give some commentary around that. That would be great. Thanks.

Janice Stipp

Analyst

We definitely are very disciplined in that approach on price down, so we look at it. And we actually ensure that we are actually getting higher earnings for and you kind of price down and getting higher volumes associated with it. So, we do not just take price downs, so we are not a commodity type business, where we are going to entertain just to maintain the business. So we look at it, and ensure that we are getting the volume, looking for the capacity and right-size our capacities and balance our facilities around the world with this price down. So, there is more than just a price down we actually look at where we can manufacture the product also. So there is many things that we look at.

Bruce Hoechner

Analyst

Yes. That's right. And in very specific area that we have this situation, so it's not broad, I wouldn't want to lead anybody to think that there is a broad situation here on pricing. It's a very specific focused initiative.

Sean Hannan

Analyst

Okay, great. And then, in terms of the commentary to the EMS, there is some caution, I think with the production staff with Blackberry, how much of that is in your guidance here, how should we think about that? Thanks.

Bruce Hoechner

Analyst

Really in EMS, we participate across essentially all of the handheld smartphone suppliers. And there was one in particular that had a problem with one of their models; they pulled it from the stores. And that we think will have some minor effect on us moving forward and that's a cautionary note that we said for Q4. But, again, this is very specific to that one manufacturer. We see continued opportunities in this area particularly in the back pad area. And I mentioned in the prepared statements around OLED as that display technology becomes more popular. We are seeing opportunities for the back pads that we have developed specifically for that application. So there is some minor issues perhaps in Q4 here as that one OEM of smartphones deals with their problems. We see that rebounding whether they get their business back or one of the other folks who makes handhelds takes that share as I mentioned earlier, essentially in all of these handhelds.

Sean Hannan

Analyst

Great. Thanks Bruce for helping to classify it with the other guy. So, then last question here for the moment. The M&A environment, so it's obviously crucial to some of your growth strategy, it's been a little bit of time since your last sizeable transaction. Can you talk a little bit about the M&A environment for your folks as well as your appetite at this point? Thanks.

Bruce Hoechner

Analyst

So our appetite is still strong, we still see this as part of our growth strategy moving forward, the synergistic M&A. Bob Daigle has been doing a lot of work on this. I'm going to ask Bob to expand upon that.

Bob Daigle

Analyst

We have been very focused and have actually -- significantly increased the activity around trying to get a larger pipeline in place because you have always run into the issue of -- you maybe interested in something, but question is it for sale and can you get the deal closed. Arlon was an excellent transaction for us in terms of overlapping very nicely bringing new capabilities to two of our key businesses. And that's really our focal point right now, we see some very nice opportunities frankly in terms of adding capabilities and either caps and capabilities or close adjacencies for our businesses. And our focus right now is really on getting that large pipeline in place so that we can improve our cadence here in terms of executing on transactions successfully.

Sean Hannan

Analyst

Thanks so much, Bob. I will hop back in the queue.

Bob Daigle

Analyst

Okay. Thanks Sean.

Operator

Operator

The next question is from Craig Ellis with B. Riley. Your line is open.

Craig Ellis

Analyst

Thanks for taking the question and congratulations on the execution in the quarter. I wanted to start just with a clarification on the upside and the third quarter. What specifically was the strength versus the mid-point of the guidance versus your expectation?

Janice Stipp

Analyst

For the third quarter or the fourth quarter?

Craig Ellis

Analyst

For the third quarter.

Janice Stipp

Analyst

For the third quarter? I mean, it really -- the reason why we excel so much is, EMS was really strong in the portable electronics market and that really what's drove our sales and our guidance and our results compared to that. So we are very happy about that. It is a pick up in the third quarter. The fourth quarter obviously the sales are a little bit down because the seasonality of the portable electronics on it. You see the fourth quarter is going down, but EMS was definitely a great improvement story for us in the third quarter.

Bob Daigle

Analyst

I can just add a little bit to that. I think the two major areas of strength for EMS, we referred to one and Bruce talked about the back pad application, which over the past year, we have kind of -- we were talking about the fact that we have been getting some nice design activity. And that showed up very strongly in the third quarter. The other area that frankly came in really strong and we were very happy with was the activities in China in the HEV/EV battery area. We do an awful a lot of work with many -- most of those the global players in the electric vehicle market. And we saw some very, very nice activity in China in particular in the EV area that was very helpful to revenues for EMS.

Bruce Hoechner

Analyst

Very interesting to see. I wanted the market dynamics that we are observing in China specifically with the focus that the government as on reducing CO2 emissions particularly in the first tier cities the Beijings, the Shanghais. There is lotteries for people to buy cars and to buy an internal combustion engine car, the lottery, you will be one out of 700 people that will be awarded that license for that car, whereas in an HEV/EV automobile it's much, much easier. So, what we are seeing is a significant up tick in activities around designs and actual commercialization of EV/HEVs in China.

Craig Ellis

Analyst

That's very helpful color. To follow-up on the back pad opportunity Bob, when we do the work with different parts of the supply chain whether it would be the display manufacturers or companies that serve them. We seem to get back to an opportunity in 2020 that would suggest 75% smartphone penetration for OLED versus what's around 20% today. So the question is not much whether that's the right or the wrong forecast, but within a smartphone market that's got form factor, differentiation, small versus larger and significant customer differentiation. As Rogers looks ahead, how do you look at the opportunity, is there a good opportunity for Rogers across small and large screen sizes. And is there anything that would preclude you from participating with any of the major OEMs whether they be Chinese screen or the U.S.?

Bob Daigle

Analyst

Yes. So, I think if we step back and think about what's the attractive aspect of OLED for us, it comes down to whether you are talking about larger or smaller screen OLED display it tend to be relatively fragile compared to the LTE module. So, you end up on a situation where protecting that OLED screen when somebody is going to drop their phone and they are not shattered, front of the device. You need higher performing basically impact protection. And that play very much to our strength. That's been our -- some area which we generally done extremely well when you got more extreme demands for physical or display or other technology in the devices we do well. I mean you had OLED display other, couple of you have asked me, in television screens and you are not likely to see back pads and television screen because you are not supposed to drop your -- you are not supposed to drop your television, and if it breaks you expect it to break. But in a handheld situation people get awfully upset when they got a device they paid $500 for and drop it on the ground and it breaks. So, we think it's a great opportunity. So definitely a nice technology tailwind that should -- we should be able to capitalize on.

Craig Ellis

Analyst

Thanks for that. Janice, looking at the outlook, is it fair to say that on the gross margin line the tailwinds would be efficiency and utilization initiatives the headwind would be volumes sequentially. How does that shake out on a quarter-on-quarter basis for that line item?

Janice Stipp

Analyst

Well, between Q3 and Q4, I mean obviously, we -- exactly what you are saying, I mean, we do see the mix and the shift and we see -- assessing like the OLED and the back pad has a high very -- improvement in our margins and some of the other sides. You will see the volume improving and you will see the mix going higher because of that. So, we see the margin improvement. In addition, to our performance initiatives and our operational excellence, [indiscernible] some of the performance, all of that is really incorporated in our guidance.

Bruce Hoechner

Analyst

And I will just add on the operational excellence side and so forth. We are accelerating our efforts there. And so we should -- as we move through certainly in this quarter in Q4 and moving to 2017. There is more to be had there certainly.

Craig Ellis

Analyst

Okay. Last question, and then, I will hop back in the queue. Bruce, I believe it was in your comments where, discussing the antenna opportunity, you mentioned that you'd like to attack that opportunity more broadly. Can you just go into more detail about what's possible there for the company?

Bruce Hoechner

Analyst

Sure. This is really geographic penetration where we play today. We play with some specific antenna accounts. And they are specific in geographical location. We have been broadening our participation with our capabilities from the Arlon acquisition much more broadly. So, we are already starting to see design wins with other antenna manufacturers that we think will bear fruit particularly as we expansion in the 4.5G massive MIMO in places like China. We do have good strong representation in India at this point and we are seeing a pick for us in China with some of our newer customer base there.

Craig Ellis

Analyst

Sounds promising. Thanks everyone.

Operator

Operator

[Operator Instructions] The next question is from Joan Tong with Sidoti & Company. Your line is open.

Joan Tong

Analyst

Hi. How are you guys doing? Good. Just a couple of questions just going back to the ACS segment and Bob, you mentioned the 4.5G new hardware demand and also 5G new design activities, is there any particular geographic region that you are seeing those types of strength and the new design activity or is it pretty much across the board around the globe?

Bob Daigle

Analyst

Yes. So, I think -- I characterize all the major telecom equipment OEMs are very busy developing hardware for the 4.5G advanced, for example, in 5G. So, I think it's across the board Joan. I think everybody sees that it's the future. I think if you look at the cost and I should have mentioned that earlier. I think one of the things that we are also very encouraged by is the fact that a lot of the -- some of the frequencies are going up quite a bit -- some of the structure for example, for 5G that they are looking at for fixed point is 28 gigahertz why because it's really cheap bandwidth. And if you look at it as a cost per megabit per subscriber, per customer, it's a very cost effective way to provide high bandwidth to customer. So, I think everyone looks at this and says this is the future; this is what the industry needs to provide the performance customers are looking at in their handhelds and everybody is looking on it. And we are working with everybody.

Joan Tong

Analyst

Okay. That’s good. And then, just another follow-up on the OLED opportunity, the back pad, on the portable electronic side of things, I'm just wondering like -- in your pipeline maybe you can't really share the information. But, obviously, somebody else already mentioned the form factor and like, different portable devices. Should we like think about this is not just a smartphone end market and you actually in your pipeline, you are actually talking to some of those like OEMs on the mobile computing side as well i.e., laptops and tablet?

Bob Daigle

Analyst

Yes. So there is potentially some opportunities in the larger devices and it usually, it gets a little bit trickier Joan because we've been through this before and some equipment providers will may want something a little bit more robust. But, I always like to think about people also generally don't expect to be able to toss their laptop around and have it hold up. So, if you throw your laptop on the floor and it breaks, it's kind of like well, I shouldn't have done that. If you drop your handset, waist high and drops on the floor better not break. So, I think there will be more of a nip back frankly I think in terms of -- I think there is some opportunities but it's not clear to us yet whether it's going to be -- it's going to be as substantial in the larger devices, we will have to wait and see.

Joan Tong

Analyst

Okay. All right. That's fair. And then, I'm not sure if you guys have mentioned anything on the ADAS side and like obviously, the [Siemens] [ph] unit again, it's flat to -- it's not exactly very robust. So it's still a content play for you guys. I just want to see that through your view and like what you are thinking over the next couple of years on the -- assistance drivers sensor business?

Bob Daigle

Analyst

Sure. And let me just speak a minute or two about the automotive radar. And what that really means for Rogers is that this is a penetration play while the number of units of coursed manufactured may vary year-to-year, what we are seeing is -- it's really the penetration of these systems, the adopted crews, fine spot detection, now we are seeing our systems, our materials being used in self-driving cars. And again the industry views this growth rate of somewhere between 25% and 30% a year through 2021. And that's pretty much in line with what we are seeing on a quarterly basis as well, is a 25% to 30% growth rate. So, as I mentioned, if we do see maybe a down turn in automotive sales, it might have some small effect per unit, but it's really the story penetration in the -- in the cars that currently don't use these radar systems. And we are seeing that moving forward massively.

Joan Tong

Analyst

Okay.

Bob Daigle

Analyst

And maybe just to add something to that, I think it's penetration in terms of the number of vehicles that are starting to incorporate the safety sensing systems. But, I think the other factors that's important for us is the number of sensors per vehicle continues to raise. And it wasn't long ago where the only thing you had were two sensors for blind spot lane change assist. And then, you ended up with adopted crews pre-collusion braking. Now, you are seeing a couple of more sensors for transfers where if you are backing out of a parking spot or out of your drive way, looking sideways to see if something is coming at you to warn you. So you are seeing the continued increase on the average number of sensors per vehicle that have the systems. And again, the regulatory -- quasi-regulatory environment is very, very favorable, you got I believe by 2021 agreement with the Detroit automakers to have the pre-collusion braking systems as a standard. You got an environment in Europe right now, where if you want to get a five star safety rating you have to have active systems, you can't just rely on protecting people on accidents, air bags et cetera. You got to prevent accidents. And these sensors play a critical role in accomplishing that.

Joan Tong

Analyst

Got it. Thanks for the update. And then, finally, just a quick update on some of those more commoditized or commodity end market, you mentioned mining and energy were some of the weak spot in the past couple of quarters. Have you seen anything stabilizing obviously, the sort of the view for next year is a little bit more favorable comparable to a couple of quarter to go. And just want to see, if you have seen that as well.

Bruce Hoechner

Analyst

In the rail and mining areas, we really haven't seen the up turn yet, so we are bouncing along at the rates that we've probably seen in the last two quarters or so. And it would be difficult for us to forecast moving forward how this is going to -- where this is going because I think it's very depended on commodity pricing, oil pricing and so forth that will drive new investments there [indiscernible] goods on rails and so on. So, part of it's tied certainly to the oil prices and so forth, part of it's tied to general economic activity. And with global GDP, relatively low compared to what it's been over the last five to seven years. Our expectation is until things really start moving, we probably won't see too much change there.

Joan Tong

Analyst

Okay. All right. Thank you guys.

Janice Stipp

Analyst

Thanks.

Operator

Operator

The next question is from Sean Hannan with Needham & Company. Your line is open.

Sean Hannan

Analyst

Yes. Thanks. Just real good more than administrative question for Janice. Can you talk a little bit about the SG&A number that we have come through within the quarter, what to expect as that moving forward from here? Thanks.

Janice Stipp

Analyst

Yes. As we talked about we have some strategic initiatives, so we had a little bit higher expenses coming through in the Q3 and our number came in at about $32 million that you will see, if we file our Q. We anticipate the fourth quarter to be roughly about the same and then it will go down in 2017 as we talked about we had strategic initiatives that will [air] [ph] one time and they will finish off throughout the year of this year. But, we've some cost initiatives that we need to take down our SG&A, so on the run rate basis, you will see that improve in 2017. And then, of course, when you compare it to last year, we had about bonus, where we reversed that clearly in Q3 of 2015 where we have been growing in 2016. So those are the three pioneering reasons of -- the difference from last year and also the steady state from three to four. But, then going forward you will see some run rate improvement.

Sean Hannan

Analyst

Okay. And then, last question here for me, if you think about some of the bigger trends that are going through of that ACS and provide a little bit more wins, when do we hit that inflection point in terms of getting back to little bit better year-over-year cost, we had something based on say some of the optimism through India, 4.5G, China et cetera. Do we start to get to that by the first quarter of next year or how should we think about that change? Thanks.

Janice Stipp

Analyst

In Q4, you will see a little bit of pick-up, as we are seeing some things change especially we talked about before, 4.5 doing some other things that things are coming in with the antenna business. So we see a little bit. But, we should see some improvement in 2017. We will see that hopefully coming back stronger in 2017 especially with the auto market and the volumes increasing year-over-year that would be a big portion of it. And then we see the power and antenna business into space that improving a little bit.

Bruce Hoechner

Analyst

Exactly. I think the big driver for growth next year as we look at would be the ADAS side of things for ASC. And I would characterize it as stability in the telecom sector.

Sean Hannan

Analyst

Okay. Thanks. And then, as a follow-up on the ADAS comment, what are you assuming in terms of volumes within the market, obviously this is a content -- primarily a content story, but we had the benefit of good volume, I think that's certainly becoming a bit more neutralized, so just wanted to understand what's in your assumption?

BobDaigle

Analyst

Yes. Sean, I think -- we will share the belief the auto industry is likely to be sluggish whether you are talking about peak auto or just stabilize and even if it's down a little bit. But, I think the important point that just to reiterate what Bruce said earlier is that our ADAS story, our volume is driven by penetration. It's driven by the fact that --the higher percentage of the vehicle every year are incorporating the safety sensors and that the average number of sensors per vehicle continues to increase. So frankly, the auto volume barring a major decline is more in the noise for us. When you are talking about mid-20% kind of growth rates, which are mostly penetration story, a few percent plus or minus in autos volume doesn't necessarily move the needle much here. I think it's less than the noise frankly.

Sean Hannan

Analyst

Great. Thanks. I will see you back folks.

Janice Stipp

Analyst

Thank you.

Bob Daigle

Analyst

Thanks Sean.

Operator

The next question is from Julie Li with Drexel Hamilton. Your line is open.

Julie Li

Analyst

Thank you very much. First of all, congratulations on the solid quarter results.

Bruce Hoechner

Analyst

Thank you, Julie.

Julie Li

Analyst

My question is, the PES business we saw some pick-up EV and HEV sales this quarter, but rail business slowed down, can you share updated view on this end markets?

Bob Daigle

Analyst

So, again, the rail is tied to commodities and movement of goods on those rail systems. And while there is ongoing building of locomotives and high-speed rail, it is at a much, much lower pace than what we have seen and then what we have seen over the last two to three years. And as I mentioned earlier in the call, we don't necessarily see that rebounding significantly moving forward. What we are seeing is, I think as you mentioned it in the PES business, significant upsides on the EV/HEV side of things both I would say both on the curamik side of the business as well as the busbars side of the business. So we are seeing essentially a movement or a transition in that business around eMobility and certainly the strength and the variable frequency drives as well.

Julie Li

Analyst

And is there a material operating margin difference between HEV and PES?

We don't normally break out down -- break our product line within the business unit. But, yes, there are differences and obviously, the higher technology ones obviously would have the higher margins, but we don't break that down.

And my last question is, all merger and acquisitions, you talked about -- you are spending the pipeline and I'm wondering is there a specific product line that you are looking at, will you seek out acquisitions opportunities?

Bruce Hoechner

Analyst

So, our stated intent is looking across all of our product lines and identifying opportunities that match well with the capabilities of Rogers. It might be an extension of a materially. It might be an extension into a different market and some enablement there an acquisition would give us. But, we are looking across of our business units to identify these adjacencies and these opportunities. So, that and that's helping us have a broader aperture of opportunities because of that.
