Thanks, Tommy. Good afternoon, and thank you for joining us today. I'm very pleased to report that PerkinElmer had an excellent second quarter, delivering revenue and adjusted earnings per share significantly above our forecast and making important progress against our key strategic growth priorities. Turning to the specific financial results, second quarter total revenue was $704 million, representing growth of 29% on a reported basis, and organic growth of 10%, with each of our businesses growing organically by 10%. Euroimmun grew as expected, increasing double digits in the second quarter. However, due to the strong growth of the core businesses, Euroimmun had an immaterial impact on our overall organic growth rate in this quarter. Adjusted EPS was $0.91, an increase of 36% over Q2 last year, with operating margins expanding 180 basis points versus the second quarter last year to 19.7%.
While Jamey will discuss our financial results in more detail, we are obviously very pleased with both the breadth and level of organic growth, as well as with the significant operating margin expansion. The very strong top-line organic growth this quarter is attributable to both the fact that end markets continue to experience robust demand, as well as our successful execution of previously communicated strategic initiatives. Specifically, our focus on tailoring the portfolio to more attractive end markets where our capabilities are well-differentiated, and investing in innovative new products and services that are helping solve customers' most challenging problems, are leading to accelerating growth in each of our key end markets.
Turning first to our Discovery & Analytical Solutions business, or DAS, we are experiencing strong customer uptake of both our new imaging and analytical instrumentation, as well as solutions spanning Informatics and service in both the pharma and applied markets. Scientists and researchers are involving PerkinElmer in critical projects to discover disease insights sooner, detect contaminants more effectively, and accelerate therapies into the clinic and drugs to market. In particular, customers are using our new preclinical in vivo imaging solutions to better understand disease progression and to help develop treatments for a wide range of cancers, infectious diseases, and other disorders. On the analytical side, our growth was broad-based, as every one of our analytical offering segments experienced high single-digit growth or better.
This has been driven by customers around the world increasingly leveraging the versatility of our instruments to test for contaminants in food and the environment, as well as across industrial applications. In our Informatics and OneSource service offerings, we continue to experience very strong growth as our expanded professional and technology services improve how our pharma and biotech customers collaborate, share, harness, and interpret data. In the life sciences space, the trend toward digitization of the lab is helping fuel the race from molecule to medicine. For example, we recently introduced a new screening solution built on application programming interfaces and customizable workflows that gives R&D organizations the ability to conduct data analysis, review, and report, plus compare data from different assay types across multiple platforms, ultimately helping researchers better discover and develop new therapies.
On the diagnostic side, researchers and clinicians around the globe are rapidly adopting new technologies to accelerate disease understanding, diagnosis, and treatment, as well as enable earlier detection of diseases to improve patient outcomes. In this regard, our two major focus areas this year have been to identify key technology synergies with Euroimmun while maintaining its historical growth rate. In our core diagnostic businesses, we are strengthening our respective franchises in reproductive health and genomics by expanding our detection capabilities, product and service offerings, and continuing to build out our presence in emerging markets. With regard to Euroimmun, the business has grown mid-teens through the first half of the year, and we are ahead of our plans relative to driving product synergies as we continue to find exciting areas of collaboration between Euroimmun and our existing technologies.
We recently announced that we received FDA clearance for several new assays to use with the EUROPattern microscope. These tests, using Euroimmun's proprietary biochip technology, have the ability to provide multiple mosaics, improving lab workflow. In addition, with the EUROPattern automated microscopes, which have the leading throughput in the market, clinicians will improve efficiencies, and labs will be able to better standardize patient care. Euroimmun has also been working on advancing technical synergies in the fields of antibody and antigen development while expanding its testing menu onto PerkinElmer instrumentation. During the quarter, we also progressed in closing the gaps in liquid handling and nucleic acid extraction for Euroimmun's molecular diagnostic solutions using PerkinElmer technologies. In addition, Tulip and Euroimmun have been working together in the field of infectious diseases on developments to expand our menu of arbovirus solutions in emerging markets.
We look forward to continued development of these technical synergies and bring these solutions to market in the coming quarters. In our core diagnostic franchises of reproductive health and genomics, we experienced high single-digit growth or better. We continue to build out our capabilities and our next-generation sequencing workflow solutions to aid processes from extraction to analysis, as well as ramp up our genetic testing services. In addition, we benefited from the rising demand for diagnostic solutions in rapidly emerging, expanding markets. This was evidenced by growth from our Haoyuan blood bank screening business in China, along with strong infectious disease testing wins from our Tulip products in India, as well as Tulip's expansion through additional geographic markets outside of India, such as in Africa.
In our newborn screening area, we're also delighted to announce that we have recently received FDA approval of our mass spec-based test for lysosomal storage disorders, or LSD. Our NeoLSD kit is unique to the market and is the only FDA and CE-IVD kit approved for testing of 6 LSDs. In June, PerkinElmer closed the acquisition of RHS Limited. Based in Australia, the company provides innovative solutions in single-cell genomics. The acquisition strengthens PerkinElmer's position in molecular cytogenetics and next-generation sequencing, allowing us to offer complete sequencing-based workflow solutions for preimplantation genetic testing of aneuploidies. The acquisition is a good fit to both our reproductive health and applied genomics businesses, where tools in single-cell and genetic testing are going to play an important role in diagnostics. Also during June, we filed for CE-IVD marking for our Vanadis non-invasive prenatal screening solution.
We pre-launched the Vanadis system at the recent International Society for Prenatal Diagnosis meeting in Belgium, where we presented clinical data which showed sensitivity at least as good as both arrays and sequencing and with a lower no-call rate than existing NIPT technologies on the market. Furthermore, this system is totally integrated workflow that lab technicians will be able to operate after one week of training. The reaction from prospective customers who were briefed on the system was very positive, and we expect to receive CE-IVD approval very soon. As we've talked about in the past, our goal is to ultimately enable all women globally to have access to an accurate, low-cost method of screening of trisomies. Regarding pricing, we believe the majority of customers adopting Vanadis will prefer the reagent rental model, consistent with how most of our reproductive health customers operate today.
Consequently, pricing will be largely dependent on the number of tests the lab runs. However, we anticipate pricing to be very attractive relative to current alternatives on the market, irrespective of volume. As we ramp up our operations and service, the plan is to install the solution in 10 labs this year. We will then work with our current biochemical customers in Europe to seamlessly convert them to Vanadis as we begin to make the system available to other regions of the world. To summarize the first half of 2018, we are making excellent progress on accelerating the growth profile of the company and converting incremental revenue to increased profits while fueling meaningful investments back into the company.
As a result of the progress we are making, we are confident in once again increasing our guidance for the year, raising our full-year organic revenue growth rate to 6% for the core business, excluding Euroimmun, which, if included, would add another 100 basis points to our organic growth rate. We are also increasing our adjusted EPS to $3.65, which is $0.15 higher than our original guidance of $3.50 in January of this year and now represents an increase of 26% over last year. I'd now like to turn the call over to Jamey, who will cover our financial performance in more detail.
Thanks, Rob, and good afternoon, everyone. I'm excited to be part of PerkinElmer and optimistic about the outlook for our company. I've had the pleasure of meeting some of you since joining May 1st, and I look forward to meeting more of you in the coming weeks. I want to start with the financial highlights for the second quarter of 2018. Next, I'll provide some additional color on our served end markets and detail on other financial metrics. I'll finish with a financial summary of our second half 2018 guidance. Turning to the second quarter results, we were very pleased with the continuing strength in our business as organic revenue in the second quarter of 2018 grew approximately 10%. Adjusted revenue in the second quarter grew 29% to $704 million, with acquisitions adding approximately 16%, and foreign exchange representing a tailwind of approximately 3%.
By business segment, Diagnostics, representing approximately 40% of total sales, grew 10% organically in the second quarter, driven by solid fundamentals in our served end markets. Discovery & Analytical Solutions, representing approximately 60% of total sales, also grew approximately 10% organically in the second quarter, highlighted by broad-based strength in both the life sciences and applied end markets. I will provide some additional color on both businesses in a moment. We were very encouraged by healthy growth across all major geographies, with double-digit organic revenue growth in Asia and in Europe, and high single-digit organic revenue growth in the Americas. This represents four consecutive quarters of organic revenue growth in all major geographies. In the emerging market regions, we continue to see double-digit organic revenue growth driven by China and India.
Moving to the details of our operational performance, second quarter adjusted operating income increased 41%, and adjusted operating margins were 19.7%, up 180 basis points over the comparable prior period, including a 30-basis-point benefit from Euroimmun. Foreign exchange was a headwind of 50 basis points during the quarter. Net of acquisitions and foreign exchange, our underlying operational performance was strong in the quarter at 200 basis points of expansion, driven by strong volume leverage and productivity. We are encouraged by the efforts of our product line and sourcing teams, driving savings in each of our commodity categories. We continue to expect strong adjusted operating margin improvements over the second half of 2018 to meet our guided range of 70 to 90 basis points of expansion. As a reminder, effective January 1st, 2018, we adopted the new pension accounting standard and have restated 2017, effectively lowering adjusted operating income.
The impact versus our prior guidance is an increase in operating cost of approximately $2 million per quarter, with an offsetting increase in other income. As a result, there is no net impact to adjusted EPS. Finally, adjusted earnings per share of $0.91 exceeded our guidance by $0.05, driven by a $0.06 beat from stronger organic growth, partially offset by $0.01 from unfavorable foreign exchange. Looking further into the key drivers within our segments for the second quarter, let's start with our Discovery and Analytical Solutions business. Our second quarter results were driven by strong double-digit organic revenue growth in life sciences, coupled with high single-digit organic revenue growth in the applied market verticals. As a reminder, our life sciences business serves the pharma, biotech, and academic government end markets, and our applied markets business sells into food, environmental, and industrial verticals.
Life sciences strength was driven by a very strong performance in the pharma/biotech end market, driven by strength in the drug discovery segment. Drug discovery product sales in high-content screening and new imaging products were key contributors, as was continued strength in our OneSource and Informatics businesses. Applied market growth was solid, led by the industrial, environmental, and Asian food end markets, driven by strong instrument sales. Switching to diagnostics, revenue grew 10% organically, driven by high single-digit organic revenue growth in reproductive health and strong double-digit organic revenue growth in both genomics and immunodiagnostics. Geographically, Asian organic revenue growth was up low teens, Europe increased double digits, and Americas saw a high single-digit organic increase.
Looking at key new additions in our diagnostics business, Tulip reported high teens organic growth driven by rapid testing, and the team continues to make great strides in penetrating the Indian diagnostics market. We continue to build on our momentum in our PerkinElmer genomics testing business and feel good about achieving approximately $50 million in revenues by 2020. Broad-based growth across all disease states helped Euroimmun grow mid-teens organically through the first half of 2018, and they remain on target to achieve the organic revenue growth plan for the full year. Geographically, China and Germany were once again strong, with momentum building in the U.S. We remain on track to double Euroimmun U.S. sales this year.
As Robert Friel mentioned, we are pleased to report that we have submitted Vanadis for CE mark approval. We look forward to working with our European customers to bring this new technology to the market. We believe that our strong global customer relationships and significant cost position provides a unique opportunity to help penetrate the NIPT market and deliver increased product offerings to a larger patient population. Looking at below the line items, adjusted net interest and other expense for the second quarter was approximately $16 million, and our adjusted tax rate was approximately 17%. Looking ahead, we now see the full year adjusted tax rate at 16%, driven by increased foreign profits in lower rate jurisdictions. Turning to the balance sheet, we finished the quarter with approximately $2 billion of debt and $163 million of cash.
We exited the quarter with a net debt to adjusted EBITDA ratio of approximately 3.2 times. We remain on track to finish the year below three times. Turning to our cash flow performance, our second quarter operating cash flow from continuing operations saw a sequential improvement. Higher inventory levels supporting production moves in Singapore and China to further increase our manufacturing localization, coupled with production builds supporting stronger demand impacted the first half of 2018. In addition, we have taken on a new distribution center strategy to better fulfill customer orders while also reducing logistics costs. We have plans in place to deliver on our full-year free cash flow commitment. I would also note that our board recently approved a new two-year, $250 million share repurchase authorization, replacing the recently expired authorization.
To wrap up the second quarter, we are very pleased with our performance, which has resulted in double-digit organic revenue growth and strong adjusted operating margin expansion. Looking ahead to the second half of 2018, we continue to believe that we are well-positioned to drive solid organic revenue growth and provide strong financial results for our key stakeholders. Driven by the strong first-half performance, we are once again raising our full-year 2018 core organic revenue growth guidance to 6%. This increase excludes Euroimmun, which will add another 100 basis points. Our organic revenue growth guidance now assumes 7% organic revenue growth in core diagnostics, with Euroimmun increasing the growth rate to 9% and 6% organic growth in DAS. We now expect reported revenue for the year to be approximately $2.78 billion, which incorporates Euroimmun sales of approximately $370 million and foreign exchange tailwinds of approximately $30 million.
We are flowing through the net second quarter adjusted EPS beat and taking up our full-year adjusted earnings per share to $3.65, despite an incremental $0.04 foreign exchange headwind. This represents approximately 26% adjusted EPS growth versus 2017. For the third quarter of 2018, we are forecasting reported revenues of $675 million, representing 22% reported revenue growth versus the comparable prior period. Our guidance assumes 5% core organic growth, mid-teens growth from Euroimmun, and negligible impact from foreign currency on a year-over-year basis. In terms of adjusted earnings per share guidance, we are forecasting $0.92 for the third quarter, which represents 26% growth versus the comparable prior period. This concludes my prepared remarks. Operator, at this time, we would like to open up the call for questions.
Thank you. Ladies and gentlemen, if you have a question at this time, please press the star and then the number 1 key on your telephone keypad. If your question has been answered or you wish to remove yourself from the queue, please press the pound key. To prevent any background noise, we ask that you please place your line on mute once your question has been stated. Furthermore, we ask that you limit yourself to one question and one follow-up question. Our first question comes from the line of Steve Beuchaw of Morgan Stanley. Your line is now open.
Hi. Thanks for the time here this afternoon. Welcome, Jamey. Good to have you here on the call. I put up a high five for Corbett. Really big quarter for DAS. That's the first thing I'd like to talk about. I wonder if you could layer on any more perspective on the surge in the DAS franchise. Good growth, big step up, best quarter in I think three years. Rob, you gave us a lot of detail on the product drivers, but I wonder if you could maybe rank, order, and again, unpack it a little bit more between how much did end market health step up? How much of this is about commercial execution really hitting its stride more than a year after the sales force restructuring? How much of this is new products? Any more depth you could give us there would really help.
Well, first of all, I think it's all the above, as you pointed out. I would say, first of all, if we think about the beat in the quarter, it largely came on the instrument side. We clearly saw good strength in service and Informatics and consumables, but I would say the delta really came on the instrument side. It's a combination of things you talked about. First of all, I think clearly we're seeing better execution. If you go back, we combined the businesses back in 2016. We, as you recall, experienced a little bit of disruption there, but I think we've now got the global account customer initiative, coupled with the sales force, really focused on selling complete solutions, which is aided by the OneSource in the Informatics. I think that's going well.
I think on the innovation side, we continue to see strong uptake, not only on the new products in 2018, but continued strong growth from the products that we introduced in 2017. Things like the Avio, the NexION, the QSight are all adding strong growth. On the life science side, clearly in the imaging area, both our high-content and in vivo imaging did quite well. What I sort of alluded to in the comments, it's fairly broad-based. Even if you look across the geographies, it was quite strong as well. I think it's clearly better execution. I think it's the innovation. I think as we've heard in the last couple of weeks, I think the markets continue to be fairly robust.
Really appreciate that. The second thing that I wanted to touch on is Vanadis. It sounds like you have a series of target accounts. These are existing PerkinElmer customers. I wonder if you can give us a sense for where you think the common threads are. Are there regions that you think you have real success with here in the early days? Are there types of labs that you would characterize as appropriate? How should we think about the transition from CE mark timing, hopefully here in the near term to 2019 and Vanadis as a revenue driver? Thanks again.
I would say, first of all, obviously with the CE-IVD marking, our focus will be largely in Europe initially. I think we've talked about this in the past, but we have probably 3.5 million pregnancies that we do today with biochemical screening. Obviously the focus will be in those areas that are doing the biochemical screening today and looking to convert if not all those tests onto Vanadis.
I would see that with regard to targeted accounts, as I sort of mentioned in my remarks, we've effectively already identified 10 labs that will be getting the systems throughout the remaining part of 2018. As we sort of ramp up production, we'll look to expand that across Europe initially, and then ultimately, probably not till 2020, we'll look to expand into other geographic regions.
Thank you. Our next question comes from the line of Dan Arias of Citigroup. Your line is now open.
Good afternoon, guys. Thanks. Rob, on Euroimmun, can you just comment on the U.S. market? As you've thought a little bit more about the puts and takes there, what's your view on the investment needs you expect to have in order to maximize that opportunity? I think initially you were thinking it was more requirements on the infrastructure side than the channel side. I guess, is that still the case? Then just, yeah, overall, how are you feeling about that portion of the market and then what you can do there in the next 12 months?
As I think Jamey mentioned, Euroimmun did very well in the U.S. again. I think through the first half of the year, they've now exceeded what they did in 2017. If you just step back from Euroimmun, it had another strong quarter across all the key geographic areas of Europe, China, U.S., were all up at least double digits. I think in U.S. specifically, I think we continue to add tests as we receive FDA approval. I think in the second quarter, we added about seven additional assays to the menu. We're continuing to see expansion of our business, particularly with the larger reference labs. I think it's partly adding some to the channel, but it's probably what's going to drive the more significant growth is getting the new products out there, getting the approval received from the FDA.
I think right now, when you look at autoimmunity, we have at least globally, the largest menu of tests and probably the best specificity, which is being driven by both our biochip technology and the capabilities of Euroimmun to produce excellent recombinant antibodies and antigens. Therefore, they not only can produce very sensitive or very specific assays, but they also attract the KOLs to work with them. I think that'll continue to be the approach to continue to build out the menu. We continue to train the PerkinElmer sales force on the Euroimmun products and vice versa. I don't know that there's a huge investment required other than to just get the new products approved and out on the market.
Yep. Okay, that's helpful. Thank you. Jamey, maybe on the margin outlook for the back half of the year, obviously some good improvements sequentially here from 1Q. It does still require some acceleration in the back half to get to your 70-90 basis points expansion target. Can you just sort of comment on how you're thinking about mix and the elements that give you the confidence in order to do that in the back half?
Yeah, I think it's mostly around some extra volume in the fourth quarter, Dan. In the third quarter, it'll be primarily mixing in Euroimmun for the margin expansion. In the fourth quarter, it's both Euroimmun as well as a solid amount of volume leverage as we expect some revenue uptick there.
Thank you. Our next question comes from the line of Ross Muken of Evercore ISI. Your line is now open.
Hey, congrats guys, on a great quarter.
Thank you.
Maybe just talk a little bit about how you're thinking about China. You have a pretty varied business there now given obviously some of the recent moves and there are a number of different markets. Given all of the tariff noise, how are you thinking about sort of your manufacturing base as well as sort of any potential maybe on the capital equipment side in the third quarter for any uncertainty and just in general, kind of your view on that market as a whole?
First of all, I would say, China continues to perform well for us. It was up again double digits in the second quarter, I think we feel we're continuing to track to a strong growth opportunity. As you point out, there are some potential headwinds out there. Let me sort of take them one at a time. I'd say, first of all, on the tariff side, we think right now, based on state of play, it's not a huge headwind for us. It's probably $1 million or less, I think that's something we can either absorb in productivity or the extent it requires a little bit of pricing, I think we can get that. We don't see tariffs today as a significant issue. That's mostly coming from products produced in China and used in our supply chain.
When you look at the other way, right now, there's virtually no diagnostic products that come from the U.S. into China. Our diagnostic products come from three sources. They're either made locally, they come from Finland, or they come from Germany. We don't see much of a risk there. On the DAS side, we think there's probably $75 million-$80 million of product that goes from the U.S. into China, we've looked at our ability to move that production. Some of it we can move relatively quickly, other probably would take us six to nine months, we're starting to put some contingency plans in place that would allow us to do that. We haven't sort of pulled any triggers right now, we think we could do that in a relatively short period of time.
Like I said, within, in some cases, relatively quickly, in some cases, probably six to nine months.
It's helpful. Maybe, it sounded like Food and Applied had a really good quarter. Perten, I think you've had some pretty great performance since you bought that asset. Maybe just give us a little color on sort of the dynamics there and maybe regionally what the bias is on Applied and Food.
As you said, Applied was a good quarter for us. It was up single digits. I would say if you look at food in Asia, that was strong. That was up high single digits as well. I would say in North America and Europe, it was more in the sort of low to mid-single digits. I think that's somewhat timing. I think food for us, if you look through the first half of the year, is tracking sort of mid-single digits, but we think probably by the end it'll probably get to the high single digits. Industrial was also good for us. I think if you recall, last quarter, there was a little concern relative, though I think we were down sort of 1% on the industrial side and sort of indicated it was timing.
I think when you look at some of these end markets that are sort of sub 10% for us as sort of a percentage of our revenue, we can have things move in and out of the quarter, a couple $ million that can drive a couple hundred basis points. Industrial for us in the second quarter was up high single digits. It was pretty broad-based from a geographic perspective, if you look at industrial now year-to-date, we're sort of tracking the mid-single.
Thank you. Our next question comes from the line of Tycho Peterson of J.P. Morgan. Your line is now open.
Hey, thanks. I actually want to follow up on the China comment. There was no pull-forward dynamic this quarter. We've heard about that from a few peers. I ask because the 3Q revenue guide also looks a little bit light relative to, I think, what we've been expecting, at least.
No, I don't think so, Tycho. I think, when we look at the revenue in China, I don't see anything pull-through. I think relative to the back half, I just think it's prudent to be maybe a little on the conservative side given some of the issues that are swirling out there. I think particularly on the China side, I think we're looking to be somewhat prudent in our expectations around revenue.
Okay. On the investment side, I want to go back to Euroimmun for a minute. You had talked previously, I think, at a conference about hiring 175-200 engineers. Can you comment on that, where you are in that process? I guess, if 90% of that business is reagents, what's really driving the need there?
Yeah, I would say that the engineer hiring, the 175-200, is probably on an annual basis. If you look at the growth that the company has experienced historically, that's generally what they're hiring in any given 12-month period. I think the conversation was in the context of the Siemens discussions. I think, like I said, if you look at the historical track record of the company, it's been growing sort of mid to high teens, that workforce is R&D based. It can be some sales people, but I would say most of the engineers are going into the R&D area to sort of work with increased investment in R&D. The model there has been, as they've grown the revenue, they've tried to keep their investment in R&D at least constant as a percentage of revenue.
If you're growing at 15%, you're taking your R&D up 15%. That's what's really driving the hiring of the engineers.
Thank you. Our next question comes from the line of Dan Leonard of Deutsche Bank. Your line is now open.
Thank you. Can you offer an update on how you're doing with the PerkinElmer genomics business, the genetic testing portion specifically that you launched a year ago?
Yeah. I would say we continue to see very good uptake on the genomic testing business. It grows, or it grew well in excess of 100%, but of course it's off of a low base. I would say consistent with the strategy we discussed previously, it's focused on one, continuing to work with the states here in the U.S. to provide confirmatory testing. We also have been expanding our partnerships with pharma and biotech companies as we sort of help them in their quest to treat rare diseases. We're also seeing nice opportunities to partner with other organizations due fundamentally to, I would say, faster turnarounds in our interpretive capabilities. We're seeing a lot of opportunity. In fact, we'll probably put in another five NovaSeqs in September to handle what we expect to be the significant volume uptake here.
Okay. That's helpful. A follow-up, another product question. Can you elaborate further on progress with the QSight? I know that had some strategic implications for you as well, beyond just being a new product launch.
I would say I mentioned a little bit in the discussion around new products. I think on the DAS side, we're seeing good traction there, largely in the food applications. We hope to maybe over time to sort of expand that out into other areas. I would say on the diagnostic side, we're in the process of getting that FDA approved with our set of reagents. While we've seen some increase there, until we get FDA approval on our reagents is when you'll see the more significant ramp-up on the diagnostic side. I would say overall, we're very pleased with the performance and think it could be a nice platform to expand into other areas.
Thank you. Our next question comes from the line of Doug Schenkel of Cowen. Your line is now open.
Hey, good afternoon. This is actually Chris on for Doug today. Thanks for taking my question.
Sure.
I just have a quick clarification question to start. What was Diagnostics organic revenue growth in Q2, excluding Euroimmun? I have a follow-up.
10%.
Okay. I believe you noted revenue synergies were ahead of expectations for Euroimmun. Could you just provide a bit more detail on this commentary, specifically what testing categories or geographies are generating upside? Lastly, just a longer-term question. Given your early success with Euroimmun, should we think that mid-teens growth rate is now sustainable in 2019 and beyond?
I would say relative to the revenue synergies, I would say the comment was not necessarily related to revenue dollars, but really the projects that we're running that we think will have future revenue synergies. The way I would sort of describe those is I'd probably put those into three categories. The first one I would say around new market or really probably new product opportunities. An example there would be we're in the process of putting some of their assays on our instruments. An example would be we're combining a chemiluminescent benchtop instrument that PerkinElmer makes with some neurological assays from Euroimmun, of course, that opens up a new market for us. We're excited about that. We've got a number of those instances where we're sort of combining the capabilities of both to open up new market opportunities.
The second area, I would say, where it's more sort of cost and capability. Euroimmun, I think as we've talked about, is going to start producing antibodies across both DAS and DX, which in addition to expanding our product development opportunities and reducing our costs, we think will improve quality. That's a sort of second category. The third area, I would say in the emerging market areas, I sort of alluded to this in my prepared comments, we're developing a lateral flow infectious disease menu for emerging markets. If you think about that, Tulip has the lateral flow technology in the distribution channel, Euroimmun has the antigens.
Anyway, my comment was really we're seeing those projects advance quicker than we thought, and I would also say we're seeing more opportunities to drive the synergies across the two capabilities of the respective companies. Your second comment with regard to our confidence around continuing to expand Euroimmun into 2019 and 2020. I would say at this point, I'm going to hold off on giving any discussion or guidance around 2019 or 2020 until we probably get through with 2018.
Thank you. Our next question comes from the line of Derik de Bruin of Bank of America Merrill Lynch. Your line is now open.
Thanks. This is Mike Ryskin on for Derik. Thanks for taking the question. Real quick, just to follow up on the Euroimmun question. In 1Q, you called out that it was an $82 million amount. I'm coming at it somewhere around $88 million-$90 million in 2Q. Is that about right?
That's about right. Yep.
Okay, thanks. On the broader DAS segment, given the 10% print, on the one hand, you had a little bit of an easier comp in the first half of 2017, in particular in 2Q. Also on your comment that much of the strength or at least the surprise to the upside came from instruments which can be a little bit more bulky. Is there anything that's changed in your outlook for the second half of the year, both for either pharma or the life sciences or the applied end markets in terms of demand? Just because looking at where the numbers come out now and how it carries forward, are you feeling any more bullish? I know that you raised your DAS outlook 5%-6%, but a lot of that's already carried in the beat.
How has your outlook changed for the second half?
No, I would say if you think about the first half, as I mentioned, it's been a fairly robust macroeconomic environment, and our assumption right now is it sort of continues into the back. I wouldn't say we're anticipating any acceleration. At the same time, I don't know that we're anticipating a deceleration. We're assuming market conditions continue in the back half similar to what we saw in the first.
Thank you. Our next question comes from the line of Jack Meehan of Barclays. Your line is now open.
Hi, thanks. Good afternoon.
Yes, sir.
Rob, I was impressed with the commentary around the Discovery segment within biopharma. That seemed to accelerate the last couple of quarters. Could you elaborate just what you think is driving some of the improvement there, whether it's from the funding environment or some of the new products you talked about?
I sort of mentioned a little bit before, but I would say it really goes across a number of things. First of all, I think we're executing better. We're getting this sort of global count structure, where I think the sales force is getting better at selling the complete solutions. I think the combination of OneSource and Informatics is sort of working well relative to our customers. I think there's a category around better execution. I think there's a category around new products and the innovation. Clearly in the imaging area, both high-content and in vivo, we saw a nice step up there. In more of the applied markets, virtually across all of our technologies, we saw strong growth.
I think a lot of that can be attributed to fairly significant refresh of a number of the platforms we did in 2017. As you probably appreciate, a lot of these instrument sales do have sort of a time lag associated until you start to see the ramp up. I think a lot of the benefits we saw initially in 2017 are starting to carry through into 2018, and that's combined with, I think, better execution of the sales force, and I think robust end markets are what's leading to a very strong growth, particularly on the product side in DAS.
Great. Just as a follow-up, it looked like the primary driver of the beat was on revenue. Margins were modestly better than what we were looking for. I guess I was just a little surprised, given the magnitude of the top-line beat, more didn't drop down to EBIT. I was wondering if either you or Jamey could just maybe walk through some of the factors, FX and maybe mix that might have been a headwind in the quarter there.
Yeah. Jack, we grew 180 basis points on the OM line, and there was 50 basis points of foreign exchange in there. Just to go back through the walk. The core grew 200 basis points.
There was 50 basis points of foreign exchange headwind and then 30 basis points from Euroimmun. We think that's actually pretty strong. We also saw it on the gross margin line as well-being pretty strong. There, Euroimmun grew about 160 basis points. The core grew about 140, and we had another 50 basis points of FX headwind.
Yeah.
We felt pretty positive.
Yes. I appreciate the optimism with our ability to perform and convert. We saw gross margins up like 250 basis points. We felt pretty good about that on the flow-through. We lost a little bit through the operating line fundamentally because operating expenses, particularly on the R&D side, were a little higher.
Thank you. Our next question comes from the line of Steve Willoughby of Cleveland Research. Your line is now open.
Hi, good evening. I just have a couple of questions for you. First, Rob, I guess just thinking about the back half organic growth versus what you've done here in the first half again. You talked about, we've experienced a pretty robust macro environment in the first half of the year. You're assuming that to continue. I guess if you could maybe explain it to me one more time on, you're going from 10% organic growth this quarter, down to 5% guidance here for the third quarter and probably around similar for that in the fourth quarter is what I think is implied. Just wondering why such the large deceleration there. I have a follow-up as well.
Yeah, I would say fundamentally two. One is we've got a little bit more difficult comp in the back. The other one is, I think it's just, given what are swirling around as some potential headwinds, we think it's prudent that 5%. By the way, even with those numbers, we'll do 6% on the core. As we think about the last three years, our organic growth will go from two to four to six. Of course, if you add Euroimmun on top of that, it gets us to seven. I think we're pretty pleased with that. What I will say is we won't let that be a constraint on our possibility of beating that number.
Okay. Just confirming something you said in the past, with the timing on Vanadis, are you still expecting $10 million in revenue from that this year? One more question for Jamey on guidance. Thanks so much.
No, I think probably $10 million is a little heavy. I think what we had said in the past is sort of $5 million to $10 million, but I think it's probably more closer to $5 million than it is to $10 million. Again, because I think it's the fact that the timing of the tenders. We'll see. Our anticipation is it's going to take a little while to get these sort of calibrated and validated within the labs. You're not going to really see a lot of the reagent flow until the latter part of the year, early 2019.
Okay, perfect. Jamey, just one for you on guidance. Just as I'm thinking about an earnings bridge between the previous guidance and the new guidance. The incremental FX headwind, is that basically being offset by a lower tax rate and then you flow through the 2Q beat here? Is that the right way to think about things?
That's exactly right, Steve. Yep. It was a $0.05 beat and then $0.04 from tax and $0.04 headwind from foreign exchange. You got it.
Perfect. Thanks so much.
Thank you. Our next question comes from the line of Patrick Donnelly of Goldman Sachs. Your line is now open.
Great. Thanks, Rob. Maybe just on the genetic testing services, clearly trending well in the early innings here. First, what's the right number for this year on revenue there? Then I know you reaffirmed the $50 million number for 2020. When you look at the levers to drive upside to there, what are the key factors you're seeing?
I would say, I think the number for this year is probably 10-ish, I think is what we said. We sort of said eight to 10, and we're probably maybe tracking to the higher end of that, hopefully. I think the levers are probably more on, we're sort of putting in interpretive software so that we can process the samples a little bit faster from an interpretive standpoint. I think our throughput on the sort of sequencing side is very good. I think that's probably right now the sort of probably biggest barrier to being able to get more volume out there. I also mentioned the fact that we're planning on putting in five more NovaSeq in September. Obviously, they take a little bit the time to get sort of up and running. As I mentioned, we continue to see very good opportunities across all the areas.
Particularly even in the pharma areas I mentioned. I think what's differentiating us is probably two things, and again, we've talked about this in the past. First of all, our ability to both provide analysis of genes and proteins is really differentiating us for a lot of the pharma companies that want to say, okay, first of all, sequence and identify a genetic mutation, but at the same time can also desire to quantifying the level of specific enzymes. That's interesting. The other one is because we can collect the samples on dried blood spot cards, which again, is differentiated. We're basically the only company that can run NGS from that. That's driving a lot of demand in the pharma companies. I think the other thing we're seeing is clearly the trend is toward more whole genome sequencing as compared to panels and exomes.
This also plays into our strength as we're one of the few labs that can do clinical whole genome tests. I think there's going to be a lot of opportunity to continue to invest and build this business.
That's very helpful. Thanks. Then just a quick one on Europe, double-digit growth there, very strong. Can you just talk through anything jump out in terms of markets that we're doing better than others? It kind of jumps off the page with double-digit growth there.
A few of them, Patrick. I think what jumps out to me at least is reproductive health was quite strong for us, and the whole diagnostic segment was, I think, up mid-teens here. Reproductive health in particular was one of the big stronger players.
Yeah.
I would say when you look across DAS, it was, again, sort of fairly broad-based. Whether it was life sciences, whether it was applied markets, they were both up double digits in Europe for us.
Thank you. Our next question comes from the line of Bill Quirk of Piper Jaffray. Your line is now open.
Great. Thanks. Good afternoon, everybody.
Yeah.
A couple of questions, Rob. First off, on China, any update to some of the newborn screening programs over there? It was suggested on an earnings call earlier this afternoon that there's some renewed interest in expanding screening in China. Just curious what the latest and greatest is.
Newborns did well for us in China again, but it's in the face of declining birth rates. I would say, depending on whether it's the eastern part or the western part of China, we're seeing birth rate declines anywhere from sort of mid to actually high single digits. Some of that, as we've talked about in the past, is sort of the zodiac sign, but also clearly, there's some economic sort of impacts that are sort of putting the decline birth rate. That's being offset, as you can imagine, by expanding menus, we see a good opportunity to do that, and then increased penetration in various areas. I think you'll see, as far as increased screening, our data right now would suggest that a large portion of the Chinese newborns get screened.
Again, I don't know that there's a huge opportunity to sort of screen more babies. I think the opportunity is really on the menu side. We're seeing that across a number of regions, not only in China. I mean, even if you look at the U.S. right now, it's interesting. You continue to see fairly significant expansion of the RUSP panel, which is a sort of recommended uniform screening panel that the HHS sort of continues to put out. Even within the U.S., that continues to expand and provide nice opportunity for us to expand the menu there.
Okay. Got it. Thanks for the color. Secondly, on Vanadis, in terms of the limiting that to 10 systems or 10 labs, excuse me, here in 2018, the reason behind the limitation there, Rob, is that because of timing of tenders? Does this have anything to do with you wanting to continue to evaluate the system and make some adjustments before you open this up broader in Europe in 2019? Just trying to get us some additional color behind that. Thanks.
I think it's actually a little bit of both. The other thing to keep in mind is these systems, again, because we're just starting with it, will take some time to get installed and probably more importantly, validated. We want to sort of get them into some key customers and make sure that they're running well. At the same time, we're sort of ramping up the production of these systems. I think the combination of those factors leads us to believe to be somewhat conservative relative to volume in the back half.
Thank you. Our next question comes from the line of Brandon Couillard of Jefferies . Your line is now open.
Thanks. Good afternoon.
Yes, sir.
Just quick one for Jamey. Looks like in terms of working capital, AR, and inventories came down pretty substantially quarter-over-quarter. Was there any one-time sort of benefits there, maybe Euroimmun related? Then, despite the EPS bump to the year, you didn't change free cash flow expectations for you. Could you just speak to that?
Sure. Yeah, with regards to cash, if you look at the first half of this year, Brandon, versus the last couple of years, we're always lighter in the first half. This quarter and this half is no different in particular. I'd say the only changes that affected the second quarter as well as the first quarter, and therefore the half, is what I mentioned in my prepared remarks around what we're doing around the supply chain. Two production moves, a new distribution center strategy, and we anticipate that somewhat normalizing in the second half and being able to get to our kind of original target.
To answer your second question, we didn't increase our free cash flow target or guidance for the end of the year because of these moves, and we need to see some of them might settle out this year, some of them might settle out in the beginning of next year, but we still feel very good that we'll generate a lot of cash both in the second half and going into 2019.
Got you. It's helpful. Thank you.
Thank you. I'm showing no further questions at this time. I would now like to turn the call back to Rob Friel for closing remarks.
Great. First of all, thanks for your questions and your continued interest in PerkinElmer. We look forward to continuing to drive our mission of innovating for a healthier world while creating even greater value for our customers, shareholders, and employees. Again, thanks again, and I hope everyone has a great evening.
Ladies and gentlemen, thank you for participating in today's conference. This does conclude the program, and you may all disconnect. Everyone, have a great day.
