Thank you, Helen, and good morning, everyone. We appreciate you joining our Q4 earnings call. I'm pleased to report that we finished 2019 with great momentum. In addition to having strong revenue growth across our biopharma business, continued margin expansion and robust cash generation, we made great progress in executing our growth strategy and expanding our global capabilities. Since completing the largest U.
S. Healthcare IPO in May, we have continually improved our leverage position, empowering us to drive the innovations and breakthroughs that help our life science customers dramatically improve patient outcomes. I would like to begin by covering some business highlights since our last earnings call on Slide 3. In November, we announced a new collaboration with the National Institute of Bioprocessing Research and Training in Dublin, Ireland. NIBERT is a global center of excellence for training and research solutions for the biopharmaceutical manufacturing industry.
Its clients include a number of industry leading companies such as Pfizer, Eli Lilly, Amgen, Bristol Myers Squibb, AbbVie and Takeda. Avantor is working with NIBRT to address downstream bottlenecks and buffer preparation when producing monoclonal antibodies. In December, we opened our 9th Innovation and Customer Support Center. Our newest addition is in Shanghai, China and will support accelerated process development for biologic therapies that will advance the development of life changing treatments for patients in the region. It was specifically focused on enhancing industry capabilities in the development and manufacture of safe and effective biologic medicines such as monoclonal antibodies and cell and gene therapy.
These treatments show great potential in China and are a fast growing segment of the bioprocessing industry worldwide. We recently began a capacity expansion initiative at our Glovice, Poland site that will support the growth of our biopharma production clients across Europe. We also initiated an expansion to our single use production capabilities in Morrisville, North Carolina. We continue to experience a high win rate on new customer accounts as well as on contract renewals. I'm pleased to report that we are ahead of plan on our integration synergy targets and I remain confident with our goal of achieving $300,000,000 of synergies by the end of 2020.
We also recently successfully repriced our term loans, lowering the rate on our U. S. Dollar and euro denominated term loans by 75 basis points. And we're looking forward to repricing our bonds later this year. I also want to share some organization enhancements that we've implemented in recent weeks that will enable us to execute our long term growth strategy.
To enhance our ability to deliver workflow based solutions in the lab, we've established a global laboratory products group, which will be led by Fredrik Vanderhagen, EVP, Europe. Fredrik and his team will work to enrich our product offering and improve our solution selling for critical workflows. As with our other platform teams, laboratory products group will work closely with our regional teams to accelerate the growth of our lab products portfolio. We recently announced plans to create 2 commercial sub regions within our EMEA region. The substantial growth potential of this part of the world, especially in China, warrants more dedicated leadership, so Avonca will now have a commercial organization specifically for the India, Middle East and Africa region, IMEA, and another for the Asia Pacific region, APAC, that includes Greater China, Korea and Southeast Asia.
Deb Orie is serving as Executive Vice President for IMEA and we've hired Sven Henrichwerke as our new Executive Vice President for the Asia Pacific region. Sven brings more than 20 years of leadership in the biotech, life science and medical technology industries, including more than 12 years at GE Healthcare. We welcomed Mark Murray to Avantor as Executive Vice President of the Biomaterials and Advanced Technologies platform. Mark brings extensive global sales, marketing, operations and strategy leadership in key related industries through his more than 25 years of experience at McKinsey, Honeywell and Celanese. Lastly, Mark Centrella joined Tom's organization in December as Vice President, Corporate Strategy and M and A.
While our top priority remains deleveraging the balance sheet, it is important that we begin to rebuild our M and A capabilities and processes. Mark has a rich background in the life sciences space and has been tasked with rebuilding our M and A capability. Also earlier today, we announced that Cory Walker, Executive Vice President for the Americas region has resigned from his position to pursue a rollout side of the life sciences industry that will allow him to move his family closer to other relatives. We have already begun our search for a successor and until one is hired, I will oversee our high performing Americas region. We are fortunate to have a very experienced leadership team in our Americas region who are committed to capitalizing on the many opportunities before us in this important region and I'm confident that we won't miss a beat.
Putting the additions that I just described, we have built a high caliber leadership team over the last few years and have added significant life sciences capability and depth. Aided by the Avantor business system, the hallmark of the team continues to be its ability to execute and we're well positioned for another great year. Moving to Slide 4, you can see the financial highlights of the 4th quarter. Organic revenue growth was 4.3% for the period and 5.1% for the full year including high single digit growth in our biopharma business in the 4th quarter reflecting ongoing strength in our portfolio of customized proprietary solutions. The biopharma end markets remain healthy around the world and we experienced attractive growth in each region.
This segment accounts for approximately half of our total sales and we expect biopharma to continue to be the strongest driver of our future growth. The other growth platforms that we have discussed including Services and Biomaterials also had high single digit growth in the quarter. We did experience a continuation of softer trends in the industrial markets as we noted in the Q3 and our growth was somewhat tempered by a weaker year end budget flush in both Europe and the Americas. Our adjusted EBITDA margin for the quarter was up 12.7% excluding adverse currency impacts, reflecting an improvement of 131 basis points for the quarter and 95 basis points for the full year. These results reflect stronger volumes and pricing, a continued improving mix of proprietary product sales, the ongoing impacts of the BWR synergies and the execution discipline enabled by the Avantor Business System.
Our adjusted earnings per share increased nearly 90% this quarter to 0 point 1 $9 per share and are up approximately 62% for the full year to $0.58 per share hitting the high end of our guidance. The excellent performance reflects strong operational execution as well as the benefit of reduced interest expense and an improved tax rate. We expect that these factors will continue to drive significant earnings improvements going forward. The 4th quarter also reflected significant strength in cash flow generation and deleveraging. Our unlevered free cash flow in the quarter was $188,000,000 representing 97 percent of the adjusted net income excluding interest expense.
Net leverage declined to 4 point 6 times EBITDA in the quarter, down from 4.8 times EBITDA at the end of the 3rd quarter and from 7 times EBITDA at the beginning of the year. In addition to the impact from the IPO earlier this year, our growth in EBITDA and focus on working capital have also contributed to 2019 deleveraging. And as Tom will discuss later, we expect further improvement during 2020. With that, let me turn it over to Tom.
Thank you, Michael. I am on Slide 5 where you can see the breakdown of the 4.3% organic growth for the Q4 by region. We experienced improved growth in the Americas reflecting continued strength in the biopharma and education end markets, partially offset by lower government and healthcare spending. Europe growth was solid at 3.5%, reflecting high single digit growth in the biopharma business and double digit growth in the healthcare end market, partially offset by declines in education and government. The EMEA region enjoyed a very strong 22.7% increase in sales this period, reflecting high double digit growth in our biopharma business, most notably in proprietary materials for bioproduction.
Let me move to Slide 6, which shows sales by end market and product group for the quarter. As you can see, biopharma, which comprises about half of our sales, grew in the high single digits, while Healthcare and Advanced Technologies and Applied Materials grew low single digits. Education and Government had a low single digit decline, which reflects softer government spending across the enterprise. By product group, Q4 was a strong quarter for proprietary materials and consumables, which had a high single digit increase continuing to outpace the low single digit growth in the 3rd party materials and consumables. Services and specialty procurement continues to grow very strongly, reflecting strength in all of our service offerings.
The equipment and instrumentation group reported a mid single digit decline reflecting a soft close to the year as Michael noted earlier. Let me move to Q4 adjusted EBITDA on Slide 7. We were pleased with the 12.7% growth and 131 basis points of margin expansion. The sales growth converted very well reflecting volume leverage, continued management of pricing versus COGS inflation, the growth in our higher margin proprietary offerings and productivity, including the BWR synergies. These were slightly offset by the impact of growth investments that we continue to make, particularly in the EMEA region.
In the middle of Slide 7, you can see that 4th quarter free cash flow improved from $65,000,000 to $75,000,000 an increase of 16%, and unlevered free cash flow was $187,800,000 for the quarter. I'll cover cash performance more on a later slide. Last, as Michael mentioned, the 90% growth in our adjusted earnings per share for the quarter primarily reflects the strong operational performance driven by organic sales growth and margin expansion as well as the ongoing reduction in interest expense from our deleveraging. Slide 8 has our segment results. The Americas reported 3.1% organic revenue growth this quarter which I discussed earlier.
Despite the sales growth, management EBITDA in the Americas declined by roughly $2,000,000 and about 70 basis points. In the Q4 of 2018, we had a favorable adjustment to inventory without which the Q4 2019 management EBITDA would have grown ahead of the sales growth, reflecting strong price management relative to COGS inflation, offset by lower sales of higher margin biomaterials products and some unfavorable manufacturing variances. In Europe, the organic sales growth of 3.5% resulted in management EBITDA growth of 10.4% excluding adverse impacts of the stronger U. S. Dollar and margin expansion of 110 basis points.
We benefited in Europe from higher sales of higher margin biomaterials, bioproduction and other proprietary offerings. EMEA had a very strong performance this quarter, as I previously mentioned, with a 22.7 percent organic sales growth. Management EBITDA in EMEA increased nearly 70% and the margin rate improved by over 850 basis points to 32.4%. The strong sales of proprietary materials into bioproduction and overall volume growth were the main drivers and were slightly offset by the additional growth investments we are making in the region in the form of sales and marketing resources. Slide 9 provides an update of our free cash flow performance for the quarter and the full year.
For the quarter, we generated $75,000,000 in free cash flow, a 16% increase. For the full year, we generated $302,000,000 in free cash flow, a $140,000,000 increase or 86% from 2018. Operational performance and lower interest expense drove $129,000,000 $71,000,000 of this full year improvement respectively. These benefits were offset by a $47,000,000 growth in taxes paid reflecting the significant growth in our income notwithstanding the improved effective tax rate. The CapEx requirements to support the growth in the business continue to be modest and overall CapEx grew from $38,000,000 in 2018 to $52,000,000 in 2019.
Slides 10 and 11 provide summaries of our performance for the full year. Slide 10 presents the organic growth, which ended up at just north of 5%, pretty much in line with the model we presented at the outset of the IPO. As expected, EMEA growth exceeded double digits and each of Americas and Europe reflected mid single digit growth. On slide 11, you'll see a summary of our full year results in operating profits, cash flow and earnings per share. Following the 5.1% organic sales growth, adjusted EBITDA grew 11% and EBITDA margin improved from 16.1% to nearly 17.1% despite some headwinds from higher than expected public company costs, share based compensation and adverse foreign currency movements.
On cash flow, I discussed the drivers of the free cash flow earlier. Even excluding the benefit from deleveraging, cash flow grew 24%, which compares nicely to an already attractive 11% adjusted EBITDA growth. Adjusted EPS was $0.58 at the high end of our guidance and up nearly 62% over 2019, again, a reflection of attractive growth, margin expansion and the ongoing impacts from deleveraging and debt repricing. Turning to Slide 12, we are pleased with the pace of deleveraging and the reduction in the cost of our debt. During 2019, we reduced debt outstanding by $1,900,000,000 comprised of $1,600,000,000 from our IPO proceeds and $300,000,000 from operations.
We started the year at 7 times EBITDA leverage and ended at 4.6 times. As we've noted before, we are targeting a leverage of 2 to 4 times EBITDA and we expect to be within this range by the end of 2020. We've also been working down the cost of our debt. Through the repricings we have done on our term loans in 2019, we reduced the weighted average cost of our debt to 6.5%. Looking ahead, we see further deleveraging and significant repricing opportunities.
In particular, we have $2,000,000,000 in senior unsecured debt with a 9% coupon and $1,500,000,000 in senior secured debt with a 6% coupon, both of which offer attractive opportunities for repricing in the second half of twenty twenty. We will share more details as we get closer to that date. Our 2020 earnings guidance is on Slide 13. We expect organic revenue growth of 4% to 6%. This assumes that the market conditions from 2019 prevail and the events out of our control such as the coronavirus do not have a meaningful impact on growth.
We are also assuming that the geographic mix of our growth that is high single digit growth in EMEA and low to mid single digit growth in the Americas and Europe remains unchanged. We expect adjusted EBITDA of 1,090,000,000 dollars to $1,135,000,000 an increase of 6% to 10%. This reflects our ongoing expectation of a stronger growth in our proprietary offerings versus growth in 3rd party offerings, operating leverage on our fixed cost base, continued focus on managing the price versus inflation dynamic and the remaining integration synergies. Our guidance for adjusted earnings per share is a range of $0.74 to 0 $0.79 per share representing growth of 27% to 36%. This reflects continued strong operational improvement, lower interest expense from deleveraging and already completed repricing action and an effective tax rate in the 25% to 26% range.
We also maintain a flat share count for guidance purposes. Last, free cash flow is expected to be in the range of $450,000,000 to 500,000,000 dollars versus $302,000,000 in 2019, also reflecting the strong operational performance, lower interest payments from deleveraging and already completed repricing actions as well as our CapEx light business model. I want to thank you sincerely for your interest and investment in Avantor and for your ongoing advice and support. I will now turn the call over to the operator to begin the question and answer section.
Thank you.
The Street. So can you maybe just talk, Tom, if there are some offsets on EBITDA expansion, things we have to factor in terms of incremental investments that would lead you to be guiding below the street and I think what people were assuming for longer term EBITDA growth?
Yes, certainly. Thanks for the question, Tycho. First of all, the guide implies on the high end about 75 basis points of margin expansion. Certainly, we are shooting and targeting for more internally. We do have some incremental headwinds from what we would have had in our long term model.
There's a little bit more public company cost between having to become a SOX adopter this year and a little bit of other things like directors and officers insurance. We're doing a little bit more inflation than we had what we commit to at what we commit to at this point. And obviously, we'll update you every quarter in terms of how we're progressing on that.
Okay. And then in terms of trends on the
Q4, I guess two questions here. The government piece, was that the weakness there, just spillover from the Q3? Or was there anything incremental on the government side? And then for equipment and instrumentation sound mid single digit, you reflected you commented on the soft close to the year. Can you maybe just talk
on dynamics of the equipment business?
Yes. I mean, first of all, the overall growth, we're really pleased with the biopharma piece of it continues to track away at that high single digits. And when you look at the government piece of it, a smaller piece of the business, certainly down sorry, government and education certainly down in aggregate. The government was the bigger driver there, Tycho. It was weird.
It was almost all of the month of October was just coming out of September. It was a slowdown across all 3 regions. Then after that, it picked up and kind of flattened out by the end of the year. On the equipment piece of it, probably similar in terms of the month December was a bit lighter than the other 2 months. And we really didn't see as intense equipment purchases in the month of December as we sometimes do when we're closing out the year.
More so in Europe than anywhere else. But I don't view either of them as long term trends. I think it's timing. I mean the government piece was clearly behind us by the time November started.
Okay. Thank you.
Our next question comes from the line of Derik De Bruin from Bank of America. Your line is open.
Hi, good morning. This is Juan Avendano for Derek. I have a question. I guess, can you give us an idea of what is the penetration level of the higher margin proprietary legacy of Antor products in the VWR distribution channel? I'm curious about what percentage of the legacy of Antor products are already being fully offered and distributed globally versus what percentage of these products are yet to be offered in the VWR catalog?
Yes, Juan, this is Michael. Thanks for the question. Clearly, you're hitting on an important aspect of our model in that the growth in margins associated with proprietary part of our business are really strategic and obviously an area that we spend a lot of time investing in.
When you
look at our core portfolio that you're referencing, a lot of that content flows into our bioproduction platform, which has been growing for most of the year in the mid teens levels. And we saw that again in the Q4. And that's led by our single use portfolio, our excipients portfolio, as well as a lot of our process ingredients and such. Prior to the combination of the 2 companies, the majority of that portfolio was being offered through the BWR channel. And clearly, as we've come together, we've only deepened that, especially in geographies outside the Americas.
Our Biomaterials platform is a unique platform with real strength in the medical technology and implant area. A lot of overlap in the customer set between our legacy NuSil customers and the to drive growth on both sides of the equation. And those teams continue to work very well. So the trends are positive. It's obviously a business like this where you're earning specifications and customizing solutions.
There's a bit of a tail here as to how you would expect to see the benefits of the better channel access that we have. We would anticipate those playing out over the next number of years, but we have fully integrated these businesses and are seeing a very strong uptick in our pipeline of opportunities around the world by having proprietary content flowing through our channel.
Got it. Thank you. And then second question is, are there any other major supplier agreements that are coming up for renewal or that are being renegotiated in the near term?
Yes, Juan. I mean, as we've said before, we've got a very diverse portfolio here. I don't think any single supplier represents more than a few percentage of our total revenue. We don't have any significant contracts that would change our ability to access product in the near term. Great relationships overall.
And when you look at the growth that we've been driving with these partners over the last couple of years and the solutions that they help us enable together with our own content. We're excited by the partnerships that we've forged over many years with these suppliers and look forward to working with them going forward.
Thank you.
Our next question comes from the line of Jack Meehan from Barclays. Your line is open.
Yes. Thank you. Good morning. I wanted to focus a couple of questions on the 2020 outlook. The first one was, was hoping you could weigh in on the pacing of growth this year.
You called out in Asia Pac, I think you I heard high single digit growth for the year, but maybe obviously small percentage of revenue, but what are you assuming in terms of how that might impact the overall growth? And then also I think you have an extra day in the Q1 too. I don't know where that necessarily falls, but maybe if you could just talk about the pacing of growth with different factors, that would be helpful.
Thanks, Jack. Yes, in terms of the 2020 plan, when you look at where we ended up in 2019, most of the trends that were intact to close the year, we're fairly consistent in terms of how that stacks up for 2020. So you can think of it as I was saying in the notes, mid single digit growth for both Americas and Europe. And it will be in the mid teens kind of for Omega. That's the overall expectation.
Is that getting into what you're asking?
Yes. Thanks for the clarification. But also, I guess, as you think about how it grows Q1 through Q4, do you think it's more linear? Or are there things that just timing wise for the Q1 we should be aware of?
Yes. I mean, when you look when you consider the comps over the course of the year, Q1 will probably be on the lower end of the mid single digits, if not low single digits, and then ramping up second half of the year on the higher end of mid single digits is the way I'd characterize it.
Okay. And then, Tom, just as a second question, you highlighted the potential for some of the refinancings ahead. Within the 2020 guidance, what are you assuming in terms of interest expense? And is there a way you can help quantify us for us just what you think that could translate to in 2021 for the refinancing?
Yes. The way I look at it, Jack, is well, first of all, to answer the question, we have not assumed any additional refinancing, repricing or anything in the plan that we presented to you. So as you know, and as probably most people that follow Bonter know, we have some opportunities in the second half of the year, specifically around October, November timeframe, we're beginning to make more economic sense to consider repricing some of the bonds that we have. We have $2,000,000,000 of unsecured bonds at 9%. We have another $1,500,000,000 of secured senior secured at 6%.
And depending on where the market conditions are, we'll obviously pursue opportunities. You can kind of think of it as overall as every on a quarterly basis, every 100 basis points is probably worth about $5,000,000 or so of interest cost. And so you can pick your favorite number and do the math in terms of the impacts that a repricing could potentially have. But going back to what we put into the plan, it is only the pricing that we had after the January repricing that we successfully did, which as you might know, we reduced the rates on the term debt, maybe about $1,000,000,000 of term debt, we reduced it by 75 basis points. So that alone gives us a nice pre tax headwind or tailwind of about $8,000,000 So continue to keep our eye on that and continue to make good traction on the debt portfolio.
Thanks, Tom. Okay.
Our next question comes from the line of Vijay Kumar from Evercore ISI. Your line is open.
Hey, guys. Thanks for taking my question. So maybe Mike, a big picture question for you. Past 2 quarters, we've had some of these one offs And I hope you shared the color on the macro and the guidance range. Just in terms of modeling purposes, should the C be looking at the bottom half of the range, just given how the last two quarters have shaken out?
Is that a more prudent approach? Or I'm just curious on where you guys feel comfortable about that guidance range on the top line?
Yes. Vijay, good to hear from you. I mean, actually, we were really pleased with our overall performance in Q4. And when you look at it relative to some of our prior prints, I think it was really characterized by almost an absence of kind of one offs, very little noise in the quarter. And I think if you would have asked me kind of 2.5 months through the quarter, where I felt we were going to come in at, I probably at that point would have told you we were trending towards the high end of our guide.
The last 5 to 10 days of the month really were slower than what we had seen historically. And we hadn't planned for anything unusual to finish the year, but certainly it came in slower than what we expected, both in the Americas as well as in Europe. Had we had a normal budget flush, I think we'd be talking about a number that was probably 1 to 200 basis points higher from an organic growth standpoint. So overall, when you look at the core business, biopharma production, the biopharma platform, broadly speaking, printing at just a tick under 10%, a return to growth of our biomaterials platform at nearly 10%, continued strong double digit growth of our services platform. Our core engine is running at full speed here.
So when we then think about the guide going into 2020, I think it certainly falls squarely in line with the messaging that we've been sharing with you all over the last number of quarters in that we view this platform as a mid single digit plus grower. I think our 2019 performance falls right in line with that as does the guide that we've given you here. So I think we're optimistic about the year ahead. I think we see the end market conditions, at least as we reflected in our guide, essentially continuing in 2020 in similar fashion as 2019.
That's helpful, Mike. And just one follow-up on. I think you mentioned coronavirus. I'm assuming the guy does not bake in coronavirus. Given you guys are under NEXT in China, how if what, if any impact does coronavirus have to your business?
And you mentioned that there's some leadership transition here in Americas. Did that have any impact at all on sales performance? Thank you.
Yes. Let me address your second question first around the leadership changes that we've announced today. First, I'm super excited by some of the capabilities that we've been able to bring to the team over the last couple of years. We've brought a tremendous amount of life science depth and capability to the business. And the recent additions, particularly in China, are no different.
We're excited to introduce you all to Sven as we get an opportunity to interact in the coming months. But he's lived in the Asia region for better part of a decade, driving some of the pure platforms in the bioprocessing space, really deep experience there. And I'm looking forward to having him take the lead here and driving our growth in the region, especially in China. Relative to the change in the Americas, Corey has been an integral part of the team here over the last 3 years or so. He's still here.
We'll go
through a
transition in the month of February. Really nothing to do with the business as to why he's electing to move on. He's got a personal situation that he's needing to resolve and we're fully supportive of helping him address that through the transition. So Corey has been in place throughout the quarter. We'll continue to be in place here through part of the month here in February.
And we have a really senior team, probably understating how senior our team is in the Americas. All of the commercial leads are driving that platform forward, 25 plus years of experience in our business, and we're in good hands there. Relative to your first question around the coronavirus, I think we'd echo probably the comments that you've heard others reflect, which is I think we're early innings into this. We do have a very formal structure set up to manage a number of key work streams, including the health and safety of our own associates, making sure we're able to address any supply chain concerns. As we sit here today, we've certainly seen an uptick in demand around the world for some of the clean room supplies and personal protective equipment.
But it's hard to tell the impact that will have. These are kind of sitting on top of Chinese New Year in any event. And I think you've rightfully mentioned China for us is a more modest exposure. So at the moment, probably too early to call, but I wouldn't anticipate it having a meaningful impact on us one way or another.
Thanks, guys.
Hey, Vijay, when Michael was talking about the leadership changes, he forgot to mention
comments, Tom, and I look forward to meeting the leadership team. Good.
Our next question comes from the line of Doug Schenkel from Cowen. Your line is open.
Good morning. I wanted to talk about 3 things, biopharma, gross margin and tax rate. So on biopharma, it was another quarter of really strong growth. What's embedded for biopharma growth within 2020 guidance? And recognizing the comparisons are difficult this year, particularly in the first half, kind of going back to an earlier question, should we be thinking about that in the context of how we model out things from a quarterly cadence perspective?
Yes. Let me, Doug, take your question on biopharma. Obviously, it's been a tremendous year for that platform and would just reground the audience here on the call today. Biopharma for us is about half of our revenue and it reflects the offering both into the laboratory environment and the workflows that we service there as well as into the production environment. And we would typically see a little bit stronger growth rates in the production environment and a little bit more muted growth in the laboratory environment.
And on an aggregate basis, that platform for us in 2019 grew at 10%, which is a reflection of kind of high single digit growth in the lab environment and double digit, I think kind of mid teens level growth of bioproduction platform. And as we think about the transition into 2020, we really see no reason to change the outlook for 2020 based on that finish. Pretty similar conditions going forward is our estimate.
Okay. So to be clear, another year of high single or close to double digit growth is how you're thinking about that end market? Exactly. Okay. All right.
Gross margin, so it was up 2 10 basis points year over year, but considering the strong proprietary products growth, we actually thought it could have been up a little bit more sequentially versus Q3. How did Q4 gross margin fare versus your internal expectations? And again, recognizing some positive trends here, what are you expecting for 2020?
Yes. I
mean, when you look at Q4 and the full year, I mean, we were able Q4, we were up about 100 basis points year over year on gross margin. Certainly, as we've talked about, the volume leverage is a big help, but and we're doing a nice job on managing the price COGS mix. But the shift, the continued growth higher growth proprietary products is also a big factor for us. If we get good growth in biopharma production as an example of biomaterials, it works out quite well for us. When you look at the full year, it was similar, Doug.
I mean, not quite as dramatic from a GM improvement perspective, but still 30 basis points to 40 basis points of gross margin improvement and still seeing those same factors. We expect a similar kind of growth rate over the course of 2020 as we drive the continued proprietary growth in our proprietary products.
Okay. Thank you for that. And last one on tax rate. Tax rate was well below our expectations in the quarter. You guided 2020 to 25% to 26%.
Do you see any room for upside versus that? And then I guess at this point, I guess just a question on how you're thinking about the long term opportunity. Should we expect a steady cadence of annual declines for say the next 3 to 5 years building off of what you guided to for 2020?
Yes. Just to address the Q4, first of all, the rate was abnormally low. I think you picked up on it. And it's just a matter of cleaning up our year end reserves and finalizing some of the positions around the intercompany financing that we've talked about. We started before the IPO with a 30% plus tax rate run rate and we explained that a big part of that was some inefficiencies in our rate structure or in our structure for financing some of our international operations.
Over the course of 2019, we've kept you up to date on that. And in the Q4, really finalized the new structures to enable us to have a much more efficient tax rate. That enabled us to adjust the overall tax rate for the full year and you saw that impact come through in the Q4. I'd say, I would consider the run rate for the full year to be if I take out that one time kind of impact, somewhere in the 28% range. And when I look at 2020, the guide is 25% to 26%.
Hopefully, we'll be at the lower end of that, but we've got pretty clear line of sight to being within that range. I think longer term, Doug, we should be low 20s kind of company. We see a path in the timeframe you talked about 3 to 5 years to certainly get there. It's the activities we have to undertake impact our operations more than what we've had to undertake so far to drive the improvement. And so it's a more enterprise wide type of initiative involving supply chains, commercial teams and the like that we have to engage in to keep that progress going.
Okay. That's super helpful. Thank you.
All right. Thanks.
Our next question comes from the line of Dan Brennan from UBS.
I guess I wanted to go back to the 2020 EBITDA margin outlook. Could you just walk through what you're assuming the impact is from synergies? How much of the expansion is organic? And kind of how does that organic expansion compare to what you achieved in 2019?
Yes. When you look at the synergies for 2,000 and where we are in the program through the end of 20 19. We've made and just to take you back for everybody's benefit, the program at the outset started in November 2017. We identified $300,000,000 or so of acquisition synergies, $70,000,000 or so would have been on the commercial side and $230,000,000 or so would have been on the cost side. Making good progress on the impacts of each of those.
We're probably nearing completion with the commercial synergies part of it. And overall, we're probably on a run rate basis close to $230,000,000 as of the end of the actually closer to $250,000,000 as of the end of 2019. So actions required to get to $300,000,000 about $50,000,000 more. In terms of the impact on the EBITDA margins next year, you can think of it as somewhere in the $40,000,000 to $50,000,000 range of incremental P and L benefit on our EBITDA in 2020.
Okay, great. And then maybe I wanted to go back to a couple of the customer groups. You already addressed biopharma, but just a few of the areas that or even by product area, excuse me, that were more kind of deviated from, I think, some of the growth rates that you had kind of outlined when you guys came public. So in particular, Advanced Materials and then on the equipment instrument side, just how do we think about those going into 2020? Like what's kind of baked in?
And if you can provide any color around what the environment looks like for those? Thank you.
Yes. On the equipment and instrument side, as Tom, I think, articulated earlier, we certainly saw a lower finish to the year in that category than what we've seen historically. And it's pretty pronounced in Europe and ended up contributing about a mid single digit decline overall in the quarter. We wouldn't expect that to continue into 2020. That would tend to be more in the low single digit growth levels, and that's probably how we would think about it in 2020.
Thinking about some of the proprietary platforms that we have, obviously, we've talked a bit here on the call today about our bioproduction platform led by our single use offering that we would expect to continue to grow probably close to 20%, netting us somewhere in the mid teens overall levels.
That's kind
of what we saw in 2019, and I think we see a similar environment going forward into 2020. Our Biomaterials platform is a platform that we've talked a bit about this year, particularly in the Q3 where we saw a little bit of inventory drop leading to more of a flattish environment in that quarter. We're obviously pleased to see, as we expected, a return to high single digit growth, not quite 10% in the 4th quarter. That's a platform that when you think about it over a 12 to 18 month cycle, that's a high single digit growth platform. And we modestly underperformed that level in 2019 really owing to the inventory corrections in the Q3 that we've discussed, but would anticipate in 2020 a normalized demand environment and kind of high single digit growth.
Our advanced technology platform, which is a collection of a large number of end markets, applied markets, including aerospace, defense, our semiconductor exposure, as well as kind of a collection of a lot of another industrial applications. It's been pretty soft throughout the year. And we saw that again in 2019. And while we would be thrilled to see those markets recover in 2020, as we think about our guidance, we've really anticipated and reflected a continuation of those trends into the New Year here.
Great. Thank you.
Our next question comes from the line of Glenn Santangelo from Guggenheim. Your line is open.
Yes, thanks for taking the questions. Mike, obviously a lot of focus on this call on the top line growth rates. And in your prepared remarks, you called out some of the softness in Europe and the U. S. And I'm just kind of curious, I mean, have you really considered the competitive landscape here and done any assessment in terms of market share and maybe how that maybe has shifted with respect to some of your major business lines or geographies.
Anything on the market share front worth calling out at all? Are you purely market driven?
Well, if you look just specifically at the Q4, if you take out the last 5 days of the year, which are always very difficult to call and driven by vacation schedules and the like, we had a very, very strong quarter. Like I said earlier, probably the quarter probably wanted to be 100 to 200 basis points stronger, which would have been at the high end of our expectations in the quarter. At the level of growth that you see us driving a little over 5 percent on a full year basis, that's at worst case in line with what we see these end markets growing. And in many instances, whether that be in the bioproduction space or whether that be in the education market, we do see ourselves running ahead of the market growth rate and extending our share around the globe. So we're pleased with the positioning that we have and being able to leverage the unparalleled customer access that we have through the channel really has us positioned well to continue to bring a more complete offering to our customers around the world.
Tom, maybe if I can just follow-up with a quick question on the balance sheet. I think in your prepared remarks, you suggested that you'd hope to get the leverage within that target range of 2 to 4 times by the end of 2020. But based on our I think you'd have to pay down another $600,000,000 plus in debt and sort of given where your free cash flow estimates are for the year, could you just help us bridge that gap on how you can get there by the end of 2020? And then when you think about the capital deployment opportunities from there, any comments to make on the M and A environment based on where you sit now? Thanks very much.
Yes. Thanks, Glenn. Yes, we talked about finishing the year at about 4.6x leverage and talked about being able to get underneath 4x by the end of 2020. There's basically two factors that are driving that. Obviously, the increase in EBITDA is a big lift.
And you can see you can pick your number out of the range that you have the most confidence in. But if you think of anywhere between $75,000,000 or so of EBITDA growth that is a contributor here. And the other one is the free cash flow that we generate. We're guiding to between $450,000,000 $500,000 When you apply that to the debt between those two factors that gets you underneath the 4 times. In terms of alternative capital deployment, 1st and foremost, we continue to just focus on deleveraging.
I mean, That's where we plan for most of our cash flow to go in 2020 and will continue to be the priority. But once we get into that range, once we get into that 2 to 4 times, we do think that we'll be in a position pursue some of the opportunities that are on the market, particularly in things that would be in the proprietary offering space that Michael was referring to, particularly around biopharma, biopharma production and the like. We, as Michael mentioned, have brought on an M and A leader. We're excited about that. And that but that's something that we've clearly focused on the long term horizon, trying to find and be prepared for opportunities when our capital structure allows it.
So that's kind of overall the short term, medium term, long term, the way we're thinking about the leverage and the alternative capital deployment opportunities.
Okay. Thanks for the comments.
Our final question today will come from the line of Erin Wright from Credit Suisse. Your line is open.
Great, thanks. In the Asia region, you did mention some of the stepped up sales investments that you are making and that maybe that was a little bit of a potential offset to the strong growth that we saw across that region in the quarter. I guess was that meaningful at all? Should that then stabilize? And what exactly is going on there?
If you could describe things.
Yes. Thanks, Aaron. It's pretty consistent with what you would have seen over the course of 2019. We've stepped up our investments, particularly on sales and marketing. And then also, we have a new lab that we've opened up in Shanghai.
We've got a new clean room and distribution center in Singapore. So clearly making some investments to drive the future growth in a region that we know we're underrepresented in. We're also expanding in a way to help us grow further. Michael talked about the organizational enhancements that we've done in that regard. So it has resulted in higher G and A costs, but we think we consider those to be investments to further the growth.
Okay. And bigger picture here over the past few quarters, now you've spoken about customer retention, contract wins. I guess, how is the merger enhancing your positioning in the marketplace overall and enhancing your win rate? And how is it resonating with your customer base?
Yes. Thanks for the question. When we put these two businesses together, we were optimistic that the broad customer access that the VWR channel would provide together with a really strong mix of technologies coming from the legacy of Ontor space would certainly lead to new opportunities over the long term. And as we've now got a couple of years under our belts here and bringing these models together, I see that reflected in the lift in the revenue profile of the combined businesses. You see that in the momentum that we're seeing, especially in our biopharma business with our offering now into the lab running over the last year plus at high single digit levels.
Our customers certainly are benefiting from a more complete integrated offering that we're able to take into this into their important workflows and we see that playing out. Perhaps the piece I'm most excited about actually is the when you just look at the opportunity, the number of drugs that we're partnering with our customers on customizing solutions, earning those specifications that will really see our longer term growth molecules that we're supporting, those new therapies that we're supporting work their way through the clinical processes and ultimately get commercialized. And to me, that's probably the more important value driver of bringing these businesses together is just what this does to enhance the sustainability and growth of the platform over the long term.
Okay. Thank you.
I'd now like to turn the call back over to Michael for closing remarks.
Great. Thank you. On behalf of our more than 12,000 associates around the world, we appreciate your support of our business and for participating in our call today. As you can tell from our comments today, we are excited about our 2019 performance, our 1st year as a public company and are looking forward to another great year of revenue growth and margin expansion, significant cash generation, and as Tom has discussed here, continue deleveraging our balance sheet. I think we see the power of our business model in our 2019 results.
We're confident that we're well positioned for another great year and are excited about enabling innovations and breakthroughs that help our life science customers dramatically improve patient outcomes. Again, appreciate everyone's support here on the line. Thanks for joining the call. Have a great day, everyone.
Ladies and gentlemen, this concludes today's conference call. Thank you for participating. You may now disconnect.
