Thank you, Jackie, and good afternoon, everyone. Illumina reported a solid Q3 with revenue of $907,000,000 driven by 12% growth in our sequencing business, more than offsetting a 24% decline in arrays revenue. Total revenue included more than $30,000,000 associated with IVD licensing agreements, which was previously anticipated in the Q4. Sequencing systems and sequencing consumable revenue was largely in line with expectations. Sequencing consumable revenue of $525,000,000 grew 11% compared to the Q3 of 2018, exceeding $500,000,000 for the first time in the company's history.
Year over year dollar growth of $53,000,000 reflected consumable growth for every system in our sequencing family, excluding HiSeq. High throughput sequencing consumable shipments were almost $300,000,000 for the 3rd quarter, of which just under $200,000,000 was NovaSeq. NovaSeq consumables grew slightly more than 20% sequentially in the 3rd quarter, highlighting both the ongoing conversion from HiSeq and the expansion of sequencing volume. During the quarter, NovaSeq surpassed HiSeq X to become the platform generating the most sequencing data. NovaSeq pull through per system was once again over $1,000,000 on an annualized basis and at the highest level we've seen so far this year.
Moving to mid- and low throughput consumables, there are a couple of trends worth noting. First, we're seeing strong uptake in NextSeq Dx, our FDA regulated and CE IVD mark version of NextSeq. Shipments of NextSeq Dx have represented just over 20% of our NextSeq shipments so far this year compared to approximately 10% in 2018. We're also seeing a number of our larger MiSeq customers transition to NextSeq Dx, notably driven by growing breadth and volume of clinical applications, including oncology. Finally, we continue to see a handful of our larger NextSeq customers transitioning some or all of their sequencing volume to NovaSeq, highlighting the broadening accessibility of high intensity sequencing applications.
These trends, the increasing NextSeq VX uptake and customers transitioning to larger platforms are positive indicators for future growth, but result in lower pull through on MiSeq and NextSeq in the near term. Over time, we anticipate that these customers will grow total consumable spend with higher sample volumes, larger content size and greater depth of sequencing. Finally, library prep contributed to sequencing consumable growth with a 13% increase compared to the Q3 of 2018, driven by the strength of our NxThera Flex solutions as well as adoption of our TruSight Oncology 500 kit. Library prep continues to represent just under 15% of our total sequencing consumable revenue. Moving to sequencing systems, revenue of $142,000,000 was up 10% sequentially and up slightly from the same quarter a year ago.
As we expected, this was the strongest quarter of the year so far and in fact represented the 2nd highest shipment quarter ever for both NovaSeq and NextSeq. NextSeq ASP remains quite consistent, while NovaSeq ASP was at the lower end of the historic range due to the multiunit shipments associated with the UK Biobank. NovaSeq orders included 35% to HiSeq customers taking their first NovaSeq, bringing the total number of HiSeq customers who have at least started their conversion to roughly a third. It's clear that there is still plenty of opportunity for NovaSeq as we move into its 4th year of launch in 2020. We continue to see strong adoption among new to alumina or new to high throughput with close to a quarter of NovaSeq shipments going to these customers in the Q3.
Moving to NextSeq. 2019 has been a very strong year for NextSeq system shipments. In fact, our strongest year to date shipment performance ever, In part driven by the increasing momentum from NextSeq Dx, we expect the NextSeq portfolio to have its strongest shipment year to date. Within our low throughput system family, MiSeq, MiniSeq and iSeq shipments were up sequentially, in part driven by growth in EMEA. Once again, we see strength in the DX version with year to date MiSeq DX shipments already exceeding full year 2018.
Overall, we are very pleased with the expansion of our installed base, particularly for NovaSeq and NextSeq that reflects growing demand for sequencing and is a promising leading indicator for growth in our consumable business. Sequencing services and other revenue of $138,000,000 was up 27% from the same quarter a year ago and up 35% on a sequential basis, with higher IVD licensing and development revenue more than offsetting the decline in sequencing services associated with the completion of the GEL program in the UK. IBD licensing and oncology development contributed to revenue growth in the Q3. In combination with our TruSight Oncology program, we see a clear opportunity to accelerate clinical adoption of NGS based IVD tests through select partners, including QIAGEN and Adaptive. Through these partnerships, we expect to see multiplier effects in our patient reach and access efforts.
And you can expect Illumina to further collaborate with others to leverage our technology for clinical testing, ultimately improving patient outcomes. In the meantime, I'm pleased to share that TSO500, our 523 gene oncology panel currently available as RUO continues to progress towards GSIVD. Last month, we submitted the 1st pre market approval module to the FDA and remain committed to accelerating the adoption of comprehensive genomic profiling and moving MGS tests into standard of care over time. Arrays continue to be a headwind for Illumina in the Q3, both sequentially and year over year, primarily due to DTC. Total microarray revenue of $102,000,000 was down 24% from the Q3 of 2018, reflecting lower revenue across systems, consumables and service and other.
We are starting to see the extension of consumer genomics into sequencing based offerings. Ancestry, for example, announced last week a new product called Ancestry Health Plus that leverages NGS technology to deliver more comprehensive data on an expanded set of health conditions. While we do not expect DTC to return to growth in the near term, we do believe that individuals will be engaging more directly with their genomic information through services like this in the future, and we remain optimistic in the opportunity for consumer genomics over time. Before I hand the call over to Sam, I'd like to take a few moments to share some organizational updates. First, I'd like to welcome Joydeep Goswami, who joined Illumina last month as our Senior Vice President of Corporate Development and Strategic Planning.
Joydeep has over 2 decades of global experience across biopharma, diagnostics and research tools, including senior leadership roles developing strategy and leading new product development, partnership, licensing and M and A. We are thrilled to have him join our leadership team. And I'd also like to share that Jay Slatte will be transitioning from Illumina's Executive Chairman to Chairman as of January 1. Jay has served Illumina's Executive Chair since he stepped down as CEO in July of 2016. We thank him for his tenure as Executive Chairman and look forward to his continuing contribution as Chairman.
With that, I'll hand the call over to Sam for a review of our quarterly financials. Sam? Thanks, Francis. As discussed, 3rd quarter revenue grew 6% year over year to $907,000,000 driven by 12% growth in sequencing, partially offset by a 24% decline in microarrays. Geographically, the Americas revenue grew 8% versus the same quarter last year.
An approximately $30,000,000 headwind in arrays was offset by growth across the sequencing business, with particular strength associated with growing clinical oncology sequencing volumes. EMEA growth of 7% was in part driven by large scale initiatives, specifically the initial infrastructure investment from the UK Biobank as part of their effort to sequence 450,000 genomes. Once again, the region saw a healthy contribution from emerging markets with a handful of NovaSeq spliced into these countries, both for clinical and research use. Greater China was down 7% year over year, but allowing for the net $6,000,000 in tariff activity from the Q3 of 2018, revenue was down 1%. The region delivered strong clinical sequencing consumable growth driven by reproductive health and oncology, but this was offset by lower revenue from research customers.
Finally, APJ revenue of $63,000,000 was up 9% from the Q3 of 2018, another growth quarter for the region in part driven by Japan, with growth in both clinical and research. Moving to product revenue. Sequencing consumables grew 11% from the same quarter a year ago to $525,000,000 or 13% allowing for the tariff stocking activity in the Q3 of 2018. As Francis noted, low and mid throughput consumables were impacted by some transitional factors that resulted in Nexi pull through at the low end of our $130,000 to $160,000 range and MySeq pull through below the low end of the $40,000 to $45,000 range. Array consumables were down 10% in the same quarter a year ago, reflecting lower DTC demand.
Array service and other revenue of $23,000,000 was down 32% from the same quarter a year ago, also reflecting lower DPC volumes. Sequencing service and other revenue of CAD 138,000,000 was up 27% year over year. As a reminder, this category includes warranty and field services, licensing fees, including NICT test fees, lab service revenue and revenues associated with licensing and development agreements. Typically, the largest contributor in this category is warranty and field services, which historically represented between 50% 60% of revenue, but was below 50% this quarter. The 2nd largest contributor this quarter was revenue of more than $30,000,000 that included the IBD licensing agreement with QIAGEN.
Oncology development revenue was also up both sequentially and year over year. Sequencing service and other growth was partially offset by lower gel sequencing volumes compared to a year ago. Moving to systems. Sequencing system revenue of 142,000,000 dollars grew 3% from the Q3 of 2018 as a result of higher NovaSeq shipments. Array system revenue was 4,000,000 dollars more in line with a typical quarter, but down significantly from the Q3 of 2018 when we saw record array system shipments associated with DTC.
Combined instrument revenue represented 16% of total revenue in the quarter. Before I continue, I will highlight non GAAP results that include stock based compensation. I encourage you to review the GAAP reconciliation of these non GAAP measures, which can be found in today's release and the supplementary data available on our website. Please note that all subsequent references to net income and earnings per share refer to the results attributable to Illumina shareholders. Non GAAP gross margin of 72.5 percent was up 300 basis points sequentially and approximately 140 basis points year over year, driven by favorable mix, notably the IVD licensing and oncology development revenue reported in sequencing service and other, with year over year growth partially offset by lower instruments and consumable ASPs.
Non GAAP operating expenses of $330,000,000 were down $30,000,000 from last quarter and were lower than expected due to delayed hiring, program reprioritization and project spend that shifted from the Q3 to the Q4. Non GAAP operating margin was therefore 36.1 percent, up from 26.6 percent last quarter. Non GAAP tax rate of 15.8% was lower than expected due to prior year return adjustments and discrete tax benefits related to the release of tax reserves. For the Q3 of 2019, non GAAP net income was $286,000,000 or $1.93 per diluted share, and GAAP net income was $234,000,000 or $1.58 per diluted share, with the primary difference being unrealized losses from marketable equity securities. Cash flow from operations was $267,000,000 DSO of 54 days increased from 51 days last quarter as a result of revenue linearity in the 3rd quarter.
In terms of other items impacting cash, we repurchased $199,000,000 of common stock in the 3rd quarter, leaving approximately $289,000,000 available under the current plan at the end of the Q3. And capital expenditures were $49,000,000 in the quarter. We therefore ended the 3rd quarter with approximately 3 $200,000,000 in cash, cash equivalents and short term investments. Moving to guidance. We expect Q4 revenue to grow about 8% from the Q4 of 2018.
We expect sequencing consumables to grow in the high teens from the same quarter a year ago. We expect non GAAP gross margin to be approximately 2 50 basis points lower on a sequential basis, reflecting revenue mix and non GAAP operating expenses to increase approximately 4.50 basis points as a percent of revenue compared to last quarter, reflecting a return to more typical rates as we catch up with delayed projects and expenses from the 3rd quarter. We expect other income to be down sequentially due to lower interest rates on our cash equivalents in the 4th quarter and our tax rate to be roughly flat compared to the 15.8% reported in the 3rd quarter. For the full year, we continue to expect 2019 revenue growth of approximately 6%. We continue to expect our sequencing business to grow approximately 10% year over year, albeit with some shift in revenue mix, primarily between sequencing consumables and sequencing service and other.
We continue to expect NovaSeq shipments to be flat to slightly up from 2018. Finally, we now expect delays to be down approximately 15% from 2018, which compares to our prior expectation of down 14%. Moving to the rest of the 2019 P and L. We expect non GAAP gross margin to be slightly up compared to the 70.1% reported in 2018. We expect full year non GAAP operating expenses as a percentage of revenue to improve approximately 150 basis points versus the 42.2% reported in 2018, reflecting OpEx and headcount prioritization activities.
And we expect weighted average diluted share count to be approximately flat compared to 2018. This includes the dilutive effect of our 2021 convertible notes. As a result, non GAAP full year earnings per share is expected to be between $6.40 $6.45 GAAP earnings per share is expected to be between $6.55 $6.60 With that, I'll hand the call back to Francis. Thanks, Sam. Before we open up the call to questions, I'll make a quick comment on the CMA's provisional finding and our proposed acquisition of Pacific Biosciences.
While we're still in the process of reviewing the document, we continue to believe that this acquisition is pro competitive and in the best interest of customers and the genomics industry. We'll continue our discussions with the CMA in the weeks ahead. Looking to 2020, momentum continues to build with a growing appreciation among clinicians that genomics will be integrated into the standard of care over time. We're seeing a growing pipeline of partnerships for clinical IVDs that will expand the reach of NGS and accelerate the adoption of genomics. We continue to see favorable developments in reimbursement with almost 75% of all insured lives in the U.
S. Having some coverage for oncology panels, including some for liquid biopsy. Coverage for undiagnosed genetic disease testing continues to grow for both whole exome and whole genome sequencing. And we continue to see broader adoption of NIPT with 7 positive European NIPT reimbursement decisions in 2019 alone, including Germany's plan to reimburse NIPT for high risk pregnancies. The UK Biobank has started sequencing its 450,000 samples and we expect both all of us and the UK's National Health Service to start scaling in 2020.
And advancements in research methodology such as single cell and spatial transcriptomics has the potential to provide insights into therapeutic areas such as immunology, oncology and neurology. Illumina will continue to innovate for our customers and with partners to accelerate the availability of impactful clinical menu that will lead to a world where genomics is incorporated into the standard of care and improves outcomes. I'll now invite the operator to open up the call to questions.
Our first question comes from Tycho Peterson from JPMorgan. Your line is open. Please go ahead. Hey, thanks. Francis, can you talk on pacing for UK Biobank?
As we think next year, all of us, can you talk about how much you actually captured this quarter from UK Biobank and what you expect in the Q4? And then how we should think about POPSEQ
Biobank, as you know, signed the deal in Q3 and started to ramp up both in terms of taking their sequencing systems as well as starting sequencing in Q3. We expect that to be running for the next few quarters as they work through the 450,000 samples. And so we expect that to be a Q4 revenue driver as well as a revenue driver for next year. In terms of All of Us, we expect that to be a 2020 revenue driver, not really a 2019 the the IRB and their discussions with the FDA. And we expect them to start to ramp up in the 1st part of next year.
And I will add, Tycho, that for Q3 specifically, even though we didn't size it, we did have some instruments that we placed with the testing centers that are performing the work for the U. K. Biobanks and NovaSeq instruments that were placed in Q3 and some consumables to start doing the work on the samples. And if I just add one more thing to what Sam said, Tycho. The other national initiative that we expect to ramp up next year is the NHS.
And so we do expect that to start ramping up at the beginning of next year and we're working with them on the shape of that ramp over the course of the next year. And from then on, we expect to play out in the following years.
Okay. And if I could ask one follow-up for Sam on China. You had $14,000,000 stocking in the comp, I think, and then you said $6,000,000 net this quarter. Can you just talk about, is this still customers moving in and out, as you alluded to last quarter? Or what are kind of the underlying dynamics in China?
Yes. Thanks, Michael. So with regards to China, we did see a decline this quarter. If you normalize for that, it's roughly flat driven by the stocking that you just mentioned. But essentially what we're seeing in China is on our clinical side of the business, actually we're seeing very strong growth in clinical.
We're seeing strong growth in oncology testing, NIPT testing, genetic disease testing. Where we see weakness in China is on the research side of the business and where we've seen a decline in that part of the business. And fundamentally, we believe that's driven by research funding that's declined or is down in China driven by some of the macroeconomic concerns there. We actually have some data that says research funding is down 10% year over year. So that's really the story there.
Not as much I mean, there is some normalization related to stocking in Q3, But really, we're seeing it's a 2, 2 part story with clinical being very strong, but research being down.
Your next question comes from Puneet Souda from SVB Leerink. Your line is open. Please go ahead.
Yes. Hi, Francis. If I could just ask around the desktop units, Sort of I think in the last quarter, you gave a sense that wasn't clear what was driving some of the weakness there. Do you have any more clarity? It seems like NextSeq DX is continuing to see growth, but you pointed out a couple of comments around the pull through being on the lower end.
Could you elaborate a little bit around what is what's driving that fundamentally in the market?
Yes, sure. Thanks, Vineet. So last quarter, we talked about the fact that we were seeing lower pull through on the desktop side of the portfolio. And now we've had another quarter of data and we're seeing 2 trends play out. One trend we're seeing play out is we're seeing customers migrate and buy bigger systems.
So we're seeing the top end of the MySeq customer base when customers are opting to buy NextSeq. And at the top end in terms of usage, on the NextSeq customer base, we're seeing some customers move up to NovaSeq. So these transitions from their existing platforms to larger platforms are good signs for us. But in the near term, do put some downward pressure on the pull through as they ramp up utilization on their bigger systems. In general, customers tend to buy bigger systems because they have expectations that their usage is going to go up over time.
The second trend that we're seeing play out is, as you touched on, the NextSeq DX. And what we're seeing in actually both the MySeq portfolio and the NextSeq portfolio is that we're seeing customers start to purchase the NextSeq Dx. That's a really good sign in terms of future growth of our clinical business. And in terms of our overall NextSeq portfolio, the portion of that portfolio that NextSeq has grown from 10% of shipments last year to 20% of shipments this year. So it's a really good growth in the NextSeq DX portfolio.
Again, that's a long term positive indicator in terms of usage, but it has put some downward pressure in the near term as customers start that transition and validate the DX boxes. So those are the 2 trends that we're seeing play out at that end of the portfolio.
Okay. Thanks. And my follow-up is a bit broader. I'm going to go a bit back here in terms of the elasticity of demand that's at central pieces to alumina. When we look back at 2014, you launched HiSeq X on the market, which drove the growth and through 2015, then we saw a little bit of slowdown in 2016.
Then you launched in 2017 NovaSeq and that drove strong growth throughout 2017 2018. The elasticity of demand, it played out very well in these 2 major periods here. But now as we head into 2020 here, you seem to be suggesting that NovaSeq consumables will continue to drive growth. So I'm trying to understand the potential absence of the new instrument here and I appreciate that's really hard for you to say anything around that. But how should we think about the catalyst to that next Elasticers demand, which is key to the growth here in 2020 beyond?
Sure. So you bring up an interesting point about the look back and there is a parallel that I want to pick up that you touched on, which is what we saw before is that when we launch a new instrument and customers transition and you touched on when we launched the X, but I'll even go a little bit further than that and talk about when we launched the HiSeq. What we saw is that as customers migrate to a bigger instrument and in the HiSeq case was a couple of quarters where we saw the pull through drop through a couple of quarters and then pick up again. And that played out again a few years later, as you touched on with BX. And so when I just talked about the desktop side of the portfolio and customers were migrating up to a bigger instrument, so they were moving to the NextEac DX, for example, MiSeq, that's the exact same phenomenon, right?
So what we've learned from our customers is that when they buy a bigger box, it's an expectation that they have that they will have more business. And that's typically how it plays out. And it doesn't play out in the quarter that they buy a box. In some cases, it takes, for example, a couple of quarters in the case of the HiSeq. And so that's the elasticity that we're seeing.
Separately, you talked about the drivers that we expect to see going forward in the business. And some of the drivers include things like you just touched on the population sequencing efforts, for example, that are starting to ramp up. So for example, UK Biobank ramped up at the tail end of Q3. That's going to play out not just in Q4, but all through 2020. We talked about all of us, that's going to start in the beginning of 2020.
So really wasn't a factor in 2019 at all, but it's going to play out into 2020. Similarly, the NHS wasn't a factor at all. And in fact, this year, we were caught in the gap between gel winding down, and so less revenue this year from gel than we had last year, and the NHS not yet ramping up and that will be a factor next year. And so those are some of the things that we expect to be incremental next year over this year.
Your next question comes from Doug Schenkel from Cowen. Please go ahead. Your line is open.
Okay. Good afternoon, everybody. So starting on sequencing consumables, if we take the $14,000,000 bulk order out of the base, it looks like you grew 15% or so year over year. So on the surface, that seems to be a step in the right direction relative to first half performance. However, you still came up almost $10,000,000 light of my forecast, and that was with a bigger than expected jump in instrument revenue in the quarter.
And while I at least from my standpoint, you weren't completely clear on it in your prepared remarks, your guidance for sequencing consumable growth in the 4th quarter seems to imply that you're reducing your full year guidance assumption for sequencing consumable revenue. So first off, is my math right? 2nd, what exactly has changed and why isn't NovaSeq ramping as you expected? What conclusion should we reach on your visibility and ability to forecast overall sequencing revenue growth, given I think the expectation has been this is supposed to be more predictable? And then longer term, if we look at your history, even when we do the 2 year average growth stacks from the first half, It looks similar to what we've seen in the past where Illumina is at least a 20% sequencing consumable growth company.
Using stacks normalizes for bulk orders. So that's the reason I do it that way. As we look to the second half, when we take your 3rd quarter performance and your Q4 guidance, it seems to assume stacked growth is going to moderate to low double digit levels. Is that the new normal? Or are you looking for more than that, Francis?
And then I know that's a lot, but one more thing. It seems like the biggest driver upside in the quarter was the QIAGEN upfront platform access fee payment to you. You indicated that this was already in guidance. That said, QIAGEN talked about GeneReader as a component of their growth strategy at their June 20 Analyst Day. You last provided guidance on July 29.
It's a little hard to understand how this could go from something that was presented as an independent company's growth driver to something that you included in your guidance 39 days later. So I just want to make sure, Sam, that I'm not missing anything. Thank you.
Yes. So Doug, thank you for the questions. There's obviously a few parts to it here. So I'll start and maybe Francis can also comment. So with regards to Q3, let me start with regards to Q3 and try to clarify in terms of the sequencing consumable growth and what that looks like.
And then I'll make my way to full year expectations and what that means for sequencing consumables as well. Although I won't comment necessarily on what's the new normal, but I can give you a sense as to what Q4 looks like per our expectations. So for Q3, we grew sequencing consumables by 11%. And if you normalize with some of the stocking activity in China from last quarter, it was 13% normalized for some of the stocking activity. So that's the expectation in Q3.
And in fact, we or that's the actual results in Q3. And if you compare it to our expectations for the quarter, it was actually better than expected. So normalizing for anything related to the IVD licensing deal revenue, in fact, for the quarter, we came in slightly better than expectations because we had lower DTC revenues that were offset by better sequencing consumables revenues for the quarter itself. Now if I look at Q4 and the full year, so one thing you are correct on is the fact that we have taken guidance down slightly for modestly for sequencing consumables for the year. So initially, we were in the mid teens in terms of sequencing consumable expectation growth.
And now we're expecting sequencing consumable growth for the full year to be in the low teens. And that reduction is mostly driven by the drivers that Francis commented on earlier with regards to pull through on some of the non high throughput instruments. So the lower pull through that we're seeing with regards to NextSeq and with regards to MiSeq, that drives most of the lower guidance that we're expecting for the full year. And finally, with regards to Q4, we are now expecting Q4 to be in the high teens in terms of sequencing consumable growth. So we do get back in Q4 to our highest growth quarter in the year in terms of sequencing consumables.
Obvious, as I mentioned, we do have a modest reduction in terms of sequencing consumable output for the full year, and we're acknowledging that, and that's driven by the bench top and the desktop phenomena. And then in terms of our partnership strategy and QIAGEN in particular, we as you know, partnerships have been a core part of our sequencing strategy for a long time. In fact, when we launched the MiSeq Dx box at the end of 2013, we launched it as an open systems platform. It was cleared that way by the FDA. And since then, we've signed a number of partnerships where they build IDDs on our platform, a number in China like Berry and Burning Hawk and Amoy.
And we've been in discussions with a number of other companies over the years. We have been talking to QIAGEN for a while. We've not talked to them about GeneReader and frankly, we've learned about their GeneReader plans just like everyone else did from the news they put out. So our conversations with them have been around their IVD panels and their portfolio there and building those panels in our sequencer. And that may continue to be an important part of our strategy.
We always do the same thing with Adaptive and bring those panels to the market. And so our strategy is going to be to look for partnerships that can help us bring tests to the market and expand our clinical platform. And really, we view our sequencing technology as a platform, that engine to drive those tests.
Your next
question Maybe I'll add one more thing, Doug, just to address your point around guidance. I mean, we can't comment, as Frances said, around the timing of the discussions with QIAGEN. But we did have in our expected guidance revenue from potential partnerships and collaborations.
Your next question comes from Dan Brennan from UBS. Your line is open. Please go ahead.
Great. Thank you for taking the questions. I wanted to ask a question about the NovoSeq as we look out to the Q4, I know you're still guiding towards a doubling in placements 4Q versus 1Q. So I'm just wondering kind of what data points can you share towards confidence towards reaching that number? I know Francis in the prepared remarks or maybe in the Q and A you mentioned U.
K. Biobank and how much was incorporated or occurred in Q3. So possibly there is uptake there in Q4. And then kind of related to that, I know you mentioned about onethree of the customers have upgraded to date entering year 4. So I'm wondering as a related question, what's your confidence level in kind of the most of these customers ultimately upgrading as you've been pointing to?
And is there anything that needs to be done possibly to facilitate the rest of the customers to upgrade, whether it be pricing or possibly new flow cell introductions? Thanks.
Sure. There are a number of orthogonal vectors that lead us to feel good about NovaSeq placements in Q4. So I'll start by saying that as we look back over the year, we are very pleased with the placements of NovaSeq and also frankly next week over the course of the year. So we're entering Q4 with strong momentum around NovaSeq placements. We are we have line of sight into a pipeline of potential deals that could drive the number of placements that we need to meet the guidance that we put out, but the number will be flat to slightly up from last year.
And then if we look at how much opportunity is still left in the installed base, we talked about the fact that only about a third of the HiSeq customers have begun that upgrade journey. And so there's still a lot of greenfield opportunity in front of us that we're addressing to get to the number we get to over the course of the year. So all those vectors point to our level of comfort around the NovaSeq placements.
Your next question comes from Derik De Bruin from Bank of America. Your line is open. Please go ahead.
Hello and good afternoon. A couple of questions. First one, I just wanted to get a sense on sort of like your confidence and you talked about feeling good about all of us and NHS coming in. And so a couple of questions. One is, can you help us understand the magnitude of how you're looking at those and what they could potentially contribute as you look to that, thinking about the incremental those could be in 2020?
And I and particularly on the NHS one, I mean, is there any reason that gets pushed out given some uncertainties in the UK right now on Brexit and going on? And then I've got a follow-up.
Sure. So I'll start and talk about the deals that you talked about specifically. I'll go with the NHS. So we have no revenue really from the NHS coming in this year and that we've been working with them on the ramp up, which we have high degree of confidence that it will happen next year. In fact, we believe it will happen in the first half of next year.
What we are working with them now is what that shape of the curve looks like. And so that's still a discussion point. And so while I have high confidence that we will kick off the NHS, it will take a little bit more work for us to come back to you and say, okay, so this is what the shape of the curve over 2020 looks like. Regardless, all of it is incremental because we didn't do any NHS revenue this year at all. If you look at all of us, we're in a similar place where we are working through with the All of Us team on the ramp and that we fully expect to happen in the early part of next year also, both on the array side and on the sequencing side.
And again, all of that is incremental. I feel good about the fact that all of us has already recruited the participants. And so they have that ready to go. They have done the work around consent and return of results is what they're working on right now. So they'll have a lot of the infrastructure ready to go once it kicks off.
Again, I have high confidence that will kick off. And we'll come back to you with again what that will look like, but all of it is going to be incremental as we go into next year.
Your next question comes from Steve Bigha from Wolfe Research. Your line is open. Please go ahead.
Hi, Steve Beechaw. Happy to be here. I wanted to try to address what I think is a kind of central theme of the call. And it's the elasticity of demand associated with NovaSeq. I would agree with Puneet's comment earlier that nova driving elasticity and ultimately acceleration is really critical to the story.
So I wonder if you might be able to leverage a very unique opportunity that you
have, which is you get
to see base space, right? From period to period UCM and its data is coming through from Illumina sequencers in
a way that those of us on
the outside don't get to see. It'd be interesting to hear what you're seeing in base space and where and whether you see that for you being evidence of elasticity, not necessarily just on revenue growth today, but on data generation, project flow and aggregate demand for sequencing at the end user level?
That's a really great question, Steve. And we do, as you can imagine, monitor the activity in base space very closely to get insights into what our that
transition
transition to AnovaSeq. And so we look at it from a high throughput to high throughput conversion. So what happens to HiSeq for ex customers as they move to NovaSeq. And we look at it from a NextSeq to NovaSeq perspective to say, okay, when a customer who's a NextSeq customer primarily adds the NovaSeq, do you see a drop overall in their consumable spend because they're able to leverage the lower cost per g or not? And what we're finding in both of those scenarios is that you actually see an expansion in their consumable spend, right, that customers will add NovaSeq or will upgrade to NovaSeq because they believe that they're having growth in their business.
And so in some I'll give you some anecdotal color. So for example, we had a customer that was primarily in the NITT business, that was primarily a NextSeq customer. And really looked at their incremental NovaSeq purchase as the way they get into some of the more sequencing intensive oncology segments, for example. And so NovaSeq helped put together the business case for their entry into the oncology space. And so that's an example of a customer that had its business continuing to sequence for NIPT, primarily on NextSeq, but it's expanding its business based on the economics it can get on NovaSeq.
We also look at the kinds of applications that are driving the NovaSeq utilization. So we look hard at we expect customers to be doing genomes and certainly they are and the volume of data on NovaSeq is very high. Last quarter, we now crossed over where NovaSeq as a platform is generating more data than any other platform we have. It surpassed the HiSeq X. We expected genomes, we expect exomes and what we're finding again is those are exactly as we'd expect the biggest applications in NovaSeq.
We are not finding cases where customers that are using the NovaSeq as sort of a big machine to run other applications more cost effectively. And that's again the most 2 on genomes. And so again, we look at the mix and how customers use them and those are some of the qualitative data points that I can share with you around what we're seeing in base base.
Your next question is from Jack Meehan from Barclays. Your line is open. Please go ahead.
Thank you. Good afternoon. I just had
a 2 parter. First, one
of the things we hear from the big Popsy customers is that the volume is going to be dictated by price. So
I'm just curious if you have any thoughts on flow cell innovation
and when you think the right time is to pull the lever on price elasticity. And then more of
a guidance philosophy question, obviously some of
these big projects have been delayed. I'm curious as we're sitting here and as we get to early January, just how you're thinking about guiding around some of these big projects depending on the level of visibility that
you have at that time? That's another great question. So as we talk to our population sequencing customers and we've talked about the fact that we're actively engaged with over 50 of these initiatives now around the world, you're right in the sense that some of them will move more quickly if they could access lower price points. And so there's definitely some elasticity around the paint, some of those opportunities could move related to the price. What we are able to do and what we've done before with gels, for example, and we'll do going forward is, as we get close to an initiative getting ready to go, we do engage into discussions around looking at the term of a project.
And we have good line of sight into our own roadmap of flow cells and instruments over the term of that project. And we're able to price for our customers based on where we expect the technology to go. And so once an initiative gets closer to getting done, we can engage in those kinds of discussions to accelerate it and getting over the line. So far, pricing has not been a gating factor on any of those initiatives to get done, and we won't let it get to that, right? And as we feel that initiative is ready to go, we can engage in the discussions I talked about to make sure that we can match their needs to pricing based on the visibility into the roadmap that we have.
We also know that as we engage with them that overall, their price per patient, their price per sample is so much more than just the price of sequencing. And so we help with the reference architectures. We have examples where we have been implemented in an end to end way with a set of partners. And so we help our customers take friction out of the system and overall take the cost down for patients and for sample by helping them think about what the end to end flow could look like easily. And maybe I can comment, Jack, on the guidance philosophy.
I mean, as we talked about in the last quarter, we are taking a more, let's say, cautious approach towards some of these population genomics initiatives because there's a high degree of an uncertainty around them and it's not a perfect science. We don't have perfect visibility to them. Having said this, we will look at them individually, case by case and try to understand those that have a high degree of certainty that will start to where they will start to actually process samples, those that have recruited patients, those that are have very specific timelines and deliverables and milestones that we have visibility to. And obviously, we have discussions with the different governments around those as well. So as we look at specific ones, we have good visibility for the all of us.
We know where they are. We know what they've recruited, and we have good insights on that. So I think there's a high degree of certainty that, that will start happening in 2020. The NHS commissioning, we have a high degree of certainty that, that will start happening. It's a question of how much and what that curve looks like, as Francis alluded to earlier.
Obviously, there's ones that are in flux, like the U. K. Biobank and others that will be part of our build as well. But too early to tell you about 2020, but that's the general philosophy. And for those big ones, just to say, I mean, those are the ones that we are personally involved with.
I've been to the UK number of times now in the last 3 months. So I feel like we have good visibility into how those are playing out. Yes. And one last thing on that one, Jack, sorry. We will also be transparent on telling you which ones are included in the values and which ones are not.
So we will be very specific and transparent on that.
Your next question comes from Sung Ji Nam from BTIG. Your line is open. Please go ahead. Hi, thanks for taking the question. Just I guess another question on China.
I'm understanding there is some funding issues. I was wondering if you could comment on the competitive dynamics there if you're seeing greater competitive headwinds. Thank you. Sure.
I'll start by saying that overall, we're not really seeing a change in the competitive dynamic in China. It's a competitive environment. We are maintaining our share in China and it's something we monitor very closely. The dynamics we're seeing is that there's definitely growth playing out in the clinical market driven by oncology and NIPT, and that's strong double digit growth. And that continues to be the case.
And so we're participating in it. The other players in the market are participating in it. And there, if anything, we're doing a little bit better than holding our share. The research side of the market has slowed down. So we saw growth.
And I think we, as an industry, saw growth in that market in 2017. We saw growth in the research market in 2018. And we're definitely seeing a slowdown overall in that market this year. There are numerous data points that show that overall funding in the research arena has gone down from last year. And so we are seeing we as well as other players in that space are seeing a deceleration in the research side of the market.
So that's happening across players in the market.
Your next question comes from Bill Quirk from Piper Jaffray. Your line is open. Please go ahead.
Great. Thanks and good afternoon everyone. Two part question from my end here. So first off, with respect to the NovaSeq placements, have all the systems for the UK Biobank project been deployed? And then secondly, Francis, if you think about some of the catalysts that you highlighted at the end of your prepared comments, can you help us think about the relative importance of them?
In other words, we have a number all of them really have outstanding catalysts, be it some guidelines endorsements for things like NIPT reimbursement for rugged clinical approval for some of the tests going through FDA or obviously funding timing, which we've talked a lot about today in terms of top gen. So can you help us just think about the relative magnitude of these? Thanks.
Sure. Let me start with the UK Biobank question you had. So certainly, the labs that are doing the sequencing to the U. K. Biobank have ramped up and they are sequencing.
Now, they may choose to augment the fleet that they have over the course of the project and that's certainly a possibility, but they are off. They've got what they need to get started and they are sequencing in full force to get going. And So that happened at the end of Q3 and it will play out again in Q4 and over the course of the next year. The clinical market, it's a big question you've asked. And as you pointed out, there are a number of moving parts to the clinical market.
And so let me talk a little bit about what's most important. And I'll start in a little bit of a segment story. So I'll start with NIPT. In NIPT, the biggest drivers of growth are going to be the national decisions that are coming out of Europe. So for example, Germany is saying we're going to reimburse for high risk adding to what the UK is doing and France is doing and Denmark is doing and Netherlands is doing.
And that's actually a European story, that's true in Japan. And the U. S, it's going to be when you see the last 2 holdouts around the average risk reimbursement agreed to cover averages. So in NIPT, I'd say the big story is around getting reimbursement continuing to expand. And we're seeing that, we're making progress and that's going to be probably the biggest fuel on the fire in terms of the growth rate accelerating in NIPT.
In terms of adjunctive genetic disease and then I'll get to oncology. In genetic disease, we've made really good progress in terms of reimbursement. So in the U. S, there are over 150,000,000 covered lives now that have access to trio whole genome or whole exome sequencing in the event that the child has a genetic disease. The bottleneck there is not reimbursement.
The bottleneck there is utilization. And so although there are 250,000 children here in the U. S. That have the indication, the condition and have reimbursement in place, if we look back over the last 12 months, we had just over 1,000 tests ordered. And so in the genetic disease market and the biggest near term opportunity there is in the U.
S, the big driver is going to be around utilization and educating the physicians around when to order the test, making sure that they are able to interpret the results when they get the test. And so that's work that we are doing through our medical affairs, clinical affairs teams and through great partners and customers like Rady's Children's Hospital in San Diego that's sort of driving a lot of the awareness around genetic disease. In oncology, we're seeing very strong growth. We're seeing already we're seeing reimbursement continue to build. We're seeing panels proliferate.
And so there, there are a number of things that will drive further acceleration of that growth rate. One is the availability of an IVD product that now makes these tests accessible to community hospitals. Nearly all of the action happening in oncology, even though we're seeing big growth there is driven in the academic cancer centers, so the sophisticated labs. And so an availability of an IVD actually will catalyze further acceleration of that market. And then the continued development of precision oncology therapies, as more therapies emerge in the market, it really pulls the need for NGS testing for patients to get access to those therapies.
So those are some of
the big drivers in oncology.
Your next question comes from Vijay Kumar from Evercore ISI. Please go ahead. Your line is open.
Hey, guys. Thanks for taking my question. I had 2 quick ones. Maybe I'll start with the housekeeping one. Sam, looking at margins in the Q, can you give us a sense of what the underlying margins were ex the, I guess, the collaboration payments?
Yes. Vijay, thanks for the question and welcome to the call. We actually had very strong margins in the quarter, better than expected. And really, the key driver for that, to your question, was the revenue driven from some of the IDD licensing deals. And those are at 100% margin, because it's all margin.
That's revenue and it's all margin.
Your next question is from Mark Massaro from Canaccord Genuity. Please go ahead. Your line is open.
Hey, thank you for the question. I guess of the revenue being recognized here in Q3, how much of that was related to the platform access fee from QIAGEN? And then, I guess, more broadly, Francis, can you talk to why you think QIAGEN is an ideal partner? And just give us a sense on what types of additional kits you think will be incremental to driving additional sequencing?
Yes. I'll take the first portion of that, Mark, and thank you for the question. We haven't broken down the partnership revenue that we got from QIAGEN. But as we indicated, approximately $30,000,000 was driven by this deal, which reflects access fees and reflects some also other revenue that we recognize as well. So it's not just entirely for the access fee.
Yes. And then I'll
take the second part of that question, which is what makes them a good partner and why did you choose them and why did you choose Adaptive and how do we choose the partners that we choose? And what we are looking for is an ecosystem of partners that will expand the menu on our sequences and give us access to additional clinical domains. And so if you look at what QIAGEN has today in their portfolio and where they are strong, right? So they have a set of small cancer panels and we don't take to market any small cancer panels ourselves really. And they also have strength in other clinical domains, right?
So they have a business in infectious disease, for example, and a number of other clinical domains where they already have the commercial capability to take products to market. And so that's exciting for us. That's exciting for us as a starting point in our relationship and also gives us line of sight into how this relationship could expand into other clinical domains. Similarly, if you look at Adaptive, they have also got a terrific set of products in areas like immunology, for example, in monitoring for MRD in some blood cancers. And so they give us access to unique menu that we can take to our customers.
And so that's what you should be looking for. Our other partnerships in China, for example, Berry, Anirone, Amoy gave us access to 2 things. They gave us access to a set of tests, so many on our sequencer. And in that case, they gave us also access to geographic distribution. And so those are some of the strategic capabilities we're looking for as we sign these partnerships.
This is part of our business. This has always been part of our business plan. It is fundamentally in our opinion, fundamentally we're a platform play. And while we choose to take some end to end solutions to market ourselves in select areas, we believe the best way to maximize long term value across all the different domains that sequencing is relevant for is to view ourselves as a platform and then find the best set of partners that give us both access to menu and access to commercial reach.
Your last question is from Derik De Bruin from Bank of America. Your line is open. Please go ahead.
Great. Thanks for taking it again. So Jack essentially asked the question I wanted to on sort of the guide and elasticity, but I wanted to actually have a question follow-up that I thought of, which is I wasn't quite sure about the mid the desktop situation and why you were seeing this slowing in. Could you go through that again and just re clarify what the underlying cause of that and how you sort of see that resolving in Q4?
Yes. So we started to call that out in Q2 on the call and now we have additional quarter of data. And so what we're seeing is 2 transitions playing out. One transition playing out is we're seeing customers migrate up to bigger systems and that played out at the top end of some MiSeq customers that moved to the NextSeq platform. And similarly, we had some high volume NextSeq customers that started to purchase NovaSeq.
And so one trend playing out is customers moving up to bigger systems. And as I said before, we've seen this play out before where as customers typically move to bigger systems because they expect to do more sequencing. So while that puts some near term pressure on pull through per instrument, over time, through increased sample volume and growing business, we expect their consumer spend to grow and sort of take the pressure off the pull through per instrument. The second trend that we're seeing is people embracing the NextSeq Dx that we brought to the market. And so we saw customers both on the MySeq base as well as the NextSeq base that are starting to purchase NextSeq Dxs.
Now as a clinical box, it takes a little time for them to validate those boxes and ramp them up. And so that drove the pull through, the NextSeq pull through per instrument down in the quarter. Again, we believe long term that's a really positive trend for our business. And NextSeqDx as a percentage of total shipments grew from 10% last year in 2018 to 20% in 2019. So really good progress from a clinical perspective.
In the near term, those new DX boxes put pressure on pull through per next week until they ramp up. But again, it's a good sign for long term growth. Maybe the only thing I would add to everything Francis said is that in terms of the timeframe as to when we expect this to continue happening for, Q4 reflects the assumption that both NextSeq would be at the low end of the pull through range and MySeq would be below the pull through range. So just to be very clear, we are expecting this in Q4 and that's what's included in our current guidance.
I would now like to turn the call back over to Jackie Ross. Thank you.
Thank you, Christina. As a reminder, a replay of this call will be available at the webcast in the Investors section of our website. Thank you for joining us today. This concludes our call and we look forward to our next update following the close of 2019.
