Good day, ladies and gentlemen, and welcome to the Second Quarter 2022 Illumina Earnings Conference Call. [Operator Instructions].

I would now like to hand the call over to Salli Schwartz, Vice President of Investor Relations. Please go ahead.

Salli Schwartz — Vice President of Investor Relations

Hello, everyone, and welcome to our earnings call for the second quarter of 2022. During the call today, we will review the financial results released after the close of the market and offer commentary on our commercial activities, after which we will host a question-and-answer session. If you have not had a chance to review the earnings release, it can be found in the Investor Relations section of our website at illumina.com. Participating for Illumina today will be Francis deSouza, President and Chief Executive Officer; and Joydeep Goswami, Chief Strategy and Corporate Development Officer as well as interim Chief Financial Officer. Francis will provide an update on the state of Illumina’s business, and Joydeep will review our financial results, which include GRAIL.

As a reminder, pending the outcome of the European Commission’s investigation into Illumina’s acquisition of GRAIL, the commission has adopted an order requiring Illumina and GRAIL to be held and operated as distinct and separate entities for an interim period. Compliance with the order is monitored by an independent monitoring trustee. During this period, Illumina and GRAIL are not permitted to share confidential business information unless legally required, and GRAIL must be run independently exclusively in the best interest of GRAIL. Commercial interactions between the two companies must be undertaken at arm’s length. [Operator Instructions], and the audio portion will be archived in the Investors section of our website.

It is our intent that all forward-looking statements regarding our financial results and commercial activity made during today’s call will be protected under the Private Securities Litigation Reform Act of 1995. Forward-looking statements are subject to risks and uncertainties. Actual events or results may differ materially from those projected or discussed. All forward-looking statements are based upon current available information, and Illumina assumes no obligation to update these statements. To better understand the risks and uncertainties that could cause actual results to differ, we refer you to the documents that Illumina files with the Securities and Exchange Commission, including Illumina’s most recent Forms 10-Q and 10-K.

With that, I will now turn the call over to Francis.

Francis deSouza — Chief Executive Officer

Thank you, Salli. Good afternoon, everyone. Illumina delivered revenues of $1.16 billion in the second quarter, up 3% year-over-year or 5% on a constant currency basis. While sequencing activity across our markets was robust in the second quarter, with sequencing runs on our connected high- and mid-throughput platforms growing more than 15% year-over-year and clinical growing even faster, our second quarter results were impacted by macroeconomic challenges that we expect to play out over the next couple of quarters. Specifically, some customers experienced supply chain pressures that delayed their lab expansions, and others managed inventory and capital more conservatively. We also saw adverse effects of foreign exchange and anticipated COVID-related shutdowns in China.

The robust sequencing activity levels underlying growth of our target markets and our conversations with customers across the globe indicate these dynamics are temporary. During the quarter, we also made terrific progress on our innovation road map and are poised to soon deliver the next generation of breakthrough technologies that will fuel the next era of genomics. Turning now to performance across our platforms. In high throughput, NovaSeq shipments in Q2 grew 23% year-over-year, our highest second quarter ever. Consistent with prior quarters, clinical customers, primarily in oncology testing, drove half of our NovaSeq shipments.

In mid-throughput, NextSeq 1000/2000 orders were up 20% year-over-year. Despite some shipments shifting from Q2 to Q3 due to supply delays, Q2 NextSeq 1000/2000 shipments increased slightly year-over-year. Low throughput shipments were relatively flat year-over-year, even with the comparison to last year’s COVID surveillance-driven volume. Turning to our markets. We continue to gain traction in clinical with sequencing consumable shipments for the second quarter up 11% year-over-year and all of our clinical markets contributing to the increase.

As I mentioned earlier, we have seen continued growth in our oncology markets. In Q2, oncology consumables grew almost 20% year-over-year. An area of note is our market-leading TruSight Oncology assay. Shipments of TSO grew 45% year-over-year, and we now have delivered distributed comprehensive genomic profiling tests to every major market in the world. We have worked closely with large evidence programs to facilitate clinical utility and drive market access, and we have more than 10 pharma partners developing CDx claims with us. Most recently, we expanded our portfolio by codeveloping a new TSO 500 HRD test with Merck that leverages Illumina’s work with Myriad Genetics.

We also codeveloped a pan-cancer companion diagnostic for TSO Comprehensive EU with Bayer. Also in oncology, June marks the one-year anniversary of GRAIL’s launch of Galleri. In that time, Galleri delivered the fastest ever first year revenue ramp of a cancer screening test. GRAIL continues to drive progress in clinical evidence generation and commercial use of their multi-cancer early detection test, Galleri. The number of U.S. health systems partnering with GRAIL to offer Galleri continues to grow, most recently with the addition of Mercy, one of the 25 largest U.S. health systems, and Ochsner Health, the largest Gulf South health system.

Also, GRAIL recently partnered with AstraZeneca to develop companion diagnostic tests that will identify patients with high-risk early-stage disease. AstraZeneca will use GRAIL technology to recruit patients with early-stage cancer for AstraZeneca’s clinical studies, making cancer medicines available where there is greater potential to transform outcomes. More broadly, the trials currently underway for Galleri continue to progress. The NHS-Galleri trial in the U.K., the largest multi-cancer early detection study, has enrolled 140,000 volunteers in just over 10 months, an unprecedented speed, especially for a trial of this size.

Pending successful completion of the trial, the NHS plans to roll out Galleri to an additional one million people starting in 2024. This collaboration supports the NHS’ long-term plan to transform cancer care with three and four cancers diagnosed at an early stage by 2028. Additionally, GRAIL has completed a final analysis of its PATHFINDER study with data to be presented at the European Society of Medical Oncology Congress September nine through 13. GRAIL has made substantial progress building a network of partners that will support ongoing adoption of Galleri, but commercial progress is proceeding at a more measured pace as health systems ramp up. For these reasons, GRAIL has revised its revenue guidance for the full year 2022 to a range of $50 million to $70 million.

Turning to infectious disease and microbiology. The genomic surveillance infrastructure built on Illumina instruments during the pandemic in more than 100 countries is now being used for other diseases like monkeypox. This network is enabling a quicker genetic assessment of this new disease as momentum continues to build for a robust global pathogen infrastructure. We’re expanding our surveillance portfolio accordingly. In June, we provided select customers access to our novel viral surveillance panel based on workflows implemented for COVID-19.

The panel provides targeted sequencing for the 66 most critical viruses of global public health concern, including monkeypox and polio, and will be commercially available later this year. Our research and applied markets were relatively flat year-over-year with growth in the Americas and APJ offset by declines in EMEA and China. In the quarter, we announced our partnership with Precision Health Research, Singapore or PRECISE to sequence whole genomes of 100,000 Singaporean participants. Together, we will develop Southeast Asia’s most comprehensive population study and gather deep insights into Asian genomic diversity and key genetic, social, environmental and other factors associated with disease.

Before I update you on further advances in our innovation road map, I’ll turn the call over to Joydeep.

Joydeep Goswami, PhD — Chief Strategy and Corporate Development Officer, Interim Chief Financial Officer

Thanks, Francis. As a reminder, our second quarter financial results include the consolidated financial results for GRAIL. I’ll start by reviewing our consolidated financial results, followed by segment results for core Illumina and GRAIL, then conclude with additional remarks on our current outlook for 2022. I’ll be discussing non-GAAP results, which 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 in supplementary data available on our website. In the second quarter, consolidated revenue was $1.16 billion, up 3% year-over-year or 5% on a constant currency basis, net of the effects of hedging. Revenue was impacted by the macroeconomic factors that Francis referenced.

As you know, we had anticipated the headwinds from the China shutdowns, the negative impact of FX and slowing COVID surveillance. Each of these were slightly worse than we expected. And collectively, they drove 1/4 of the variance between our expectations and actual results. The remainder of this variance was driven by the lab expansion delays encountered by a few of our large customers as a result of global supply chain constraints as well as customer inventory and capital management. Nonetheless, overall sequencing activity on our connected instruments was strong in the second quarter with sequencing runs in our high- and mid-throughput instruments growing more than 15% year-over-year.

We believe this is a useful reference that shows the general activity trend across our installed base and is directionally correlated with revenue over time. For the second quarter, GAAP net loss was $535 million or a loss of $3.40 per diluted share, which included $609 million in legal contingencies recorded in Q2 due to the potential fine that the European Commission may impose related to our GRAIL acquisition and settlement of our litigation with BGI. Non-GAAP earnings were $91 million or $0.57 per diluted share, including dilution from GRAIL’s non-GAAP operating loss of $152 million for the quarter. Our non-GAAP tax rate was 25.8%, which increased 790 basis points year-over-year and 800 basis points from Q1 2022 primarily due to the increased impact of R&D expense capitalization requirements implemented by the Tax Cuts and Jobs Act of 2017.

Our non-GAAP weighted average diluted share count for the quarter was approximately 159 million. Moving to segment results. I will start by discussing the financial results of core Illumina. Core Illumina revenue of $1.16 billion grew 3% year-over-year or 4% on a constant currency basis, net of the effects of hedging. Core Illumina sequencing consumables grew 6% year-over-year to $744 million, driven by almost 20% growth in oncology testing. Core consumables growth more than offset headwinds from lockdowns in China, the completion of the UK Biobank program in quarter three of 2021, reductions in COVID surveillance and negative FX impacts.

Sequencing instruments revenue for core Illumina grew 1% year-over-year to $119 million, driven by 23% growth in NovaSeq shipments offset by a 14% decrease in the mid-throughput shipments year-over-year. The decrease in mid-throughput shipments was primarily due to headwinds from COVID surveillance and COVID lockdowns in China with NextSeq 1000/2000 growth more than offset by a decrease in NextSeq 550. NextSeq 1000/2000 instruments continued to grow year-over-year, and the growth would have been stronger had it not been for temporary supply constraints that delayed shipments into the third quarter. NextSeq 1000/2000 orders were up 20% year-over-year with continuing strong adoption of our newest platform.

During the second quarter, COVID surveillance contributed approximately $25 million in sequencing consumables revenue and $2 million in incremental instruments revenue, representing a decline of 55% year-over-year. This decline was driven by lower-than-expected testing samples and the expected decline in instrument shipments as COVID surveillance capacity was largely established in 2021. Core Illumina sequencing service and other revenue of $125 million was down 2% year-over-year driven by $20 million of a onetime revenue recognized in 2021 from NIPT royalties received related to a patent litigation settlement, partially offset by increased instrument service contracts and contributions from oncology codevelopment partnerships. Moving to regional results for core Illumina.

Revenue for the Americas region was $633 million, up 7% year-over-year, primarily due to NovaSeq strength with continued demand from oncology testing customers driving instrument placements and consumables grow. Growth in the region was nonetheless lower than expected primarily due to customer lab expansion delays and inventory and capital management we have mentioned during the call. EMEA revenue of $308 million represented a 4% decrease year-over-year but a 1% increase on a constant currency basis, net of the effect of hedges. Sequencing growth driven by clinical and large-scale research projects was more than offset by the UK Biobank program in 2021 and a decline in COVID surveillance revenue. Cumulatively, these significant headwinds and FX negatively impacted year-over-year revenue growth by 20 percentage points.

Greater China revenue of $118 million represented an 11% decrease year-over-year and a 10% decrease on a constant currency basis. This was slightly more negative than the approximately $35 million headwind to guidance we provided last quarter. As expected, the region continued to be impacted by prolonged COVID-19 restrictions and shutdowns that began in March this year. Finally, APJ revenue of $97 million grew 14% year-over-year or 20% on a constant currency basis, net of the effects of hedges. Growth in the region was primarily due to increased NovaSeq shipments, which doubled year-over-year, driven by large-scale research project demand as well as strength in NIPT and oncology testing.

Moving to the rest of core Illumina P&L. Core Illumina non-GAAP gross margin of 69.8% decreased 200 basis points year-over-year, primarily due to less fixed cost leverage on lower manufacturing volumes, margin impact from a onetime revenue from a patent litigation settlement in 2021 and increased freight costs attributable to broader global supply chain pressures. These factors were partially offset by a more favorable product mix as well as a number of productivity initiatives we continue to execute. Core Illumina non-GAAP operating expenses of $519 million were up $48 million year-over-year due primarily to head count growth and investments we’re making in R&D to support the continued advancements of our innovation road map.

Despite the year-over-year increase, non-GAAP core Illumina operating expenses were lower than we originally planned as a result of lower performance-based compensation expense given our lower revenue outlook and cost containment initiatives focused on select hires and discretionary spend, including travel. Transitioning to the financial results for GRAIL. GRAIL revenue of $12 million for the quarter consisted primarily of Galleri test fees. GRAIL non-GAAP operating expenses totaled $156 million for the quarter and consisted primarily of expenses related to head count and clinical trials. These expenses were lower than expected as GRAIL managed its project spend in light of its lower quarterly outlook.

Moving to consolidated cash flow and balance sheet items. Cash flow from operations was $125 million. DSO was 50 days compared to 46 days last quarter due to revenue linearity. Second quarter 2022 capital expenditures were $71 million, and free cash flow was $54 million. We did not repurchase any common stock in the quarter. We ended the quarter with approximately $1.3 billion in cash, cash equivalents and short-term investments. Moving now to 2022 guidance. We have revised our outlook for the full year to represent the macroeconomic factors we observed through early August and we assume will continue for the rest of the year.

We now expect full year 2022 consolidated revenue to grow in the range of 4% to 5%, including core Illumina revenue growth in the range of three to — 3.5% to 4.5% and GRAIL revenue of $50 million to $70 million. For the full year, at the midpoint of our revenue guidance range, we now expect core Illumina sequencing revenue to grow approximately 4.5%. This includes intercompany sales to GRAIL of approximately $25 million, which are eliminated in consolidation.

Within core Illumina sequencing revenue, we now expect instrument growth of 1.5% and consumables growth of 5%, which reflects NovaSeq pull-through in the range of $1.1 million to $1.2 million per system for 2022. We continue to expect pull-through for NextSeq 1000/2000 in the range of $130,000 to $180,000 per system and for the NextSeq 550 in the range of $100,000 to $150,000 per system. For MiSeq, we continue to expect pull-through in the range of $35,000 to $45,000 per system. And for MiniSeq, we continue to expect pull-through in the range of $20,000 to $25,000 per system. We now expect revenue from COVID surveillance in the range of $110 million to $130 million. While we anticipated a decline in COVID surveillance in 2022, the deceleration has occurred at a more rapid pace than we’ve previously forecasted.

As we navigate the macroeconomic factors we have mentioned, we’re implementing multiple strategies, including prioritizing key innovation investments and critical hires while pausing investments that can be made at later times. We’ve retained all critical investments in our innovation road map, including NovaSeqDx, Chemistry X, our Infinity long-read technology and our TSO portfolio. We now expect consolidated non-GAAP operating margin in the range of 11.5% to 12% and core Illumina non-GAAP operating margin in the range of 24.5% to 25%. We expect a consolidated non-GAAP tax rate of approximately 14%, which continues to assume that the R&D expense capitalization requirements implemented by the Tax Cuts and Jobs Act of 2017 will be repealed or deferred in Q4.

And we now expect non-GAAP earnings per diluted share in the range of $2.75 to $2.90, which includes dilution from GRAIL non-GAAP operating loss of approximately $610 million, in line with previous expectations. Lastly, we continue to expect diluted shares outstanding of approximately 159 million shares for 2022. For the third quarter of 2022, we expect consolidated revenue to be flat to 1% higher year-over-year from the third quarter of 2021. We expect consolidated non-GAAP operating margin to be approximately 5%. We expect core Illumina non-GAAP operating margin to be approximately 20%.

We expect consolidated non-GAAP tax rate to be approximately 22%, which continues to reflect the negative impact from the R&D capitalization requirements we expect will be repealed or deferred in the fourth quarter of this year. And lastly, we expect diluted shares outstanding to be in line with our full year 2022 guidance of approximately 159 million shares.

I will now hand the call back over to Francis for his final remarks.

Francis deSouza — Chief Executive Officer

Thanks, Joydeep. Turning to our innovation road map. We have significant opportunities to reimagine the power and potential of genomics. Development and registration activities for NovaSeqDx, the first-ever high-throughput clinical sequencer, are progressing as planned and on track for a Q4 launch. We continue to get good feedback from initial customers on our Infinity long-read technology with many saying it has the potential to replace on-market long reads for a broad range of applications, including human rare diseases. Infinity is on track to be available later this year for early access customers. In multiomics, our partnership with SomaLogic to accelerate NGS into proteomics is progressing, and we expect to deliver our ultra-high throughput, ultra-high plexity assay in 2024.

Turning now to Chemistry X, our next-generation breakthrough SBS chemistry. We’ve made fantastic progress over the last quarter. We’re now producing flow cells using our new manufacturing process based on 300-millimeter wafers. We successfully tested Chemistry X on the new flow cells, and the results exceed our expectations for quality, cost and speed. We’re excited to showcase these breakthroughs and reveal how they come to life at the Illumina Genomics Forum. And we look forward to hosting you at our Investor Day on October 3, where we will discuss these technologies and our long-term growth strategies. If you haven’t already registered, please be sure to do so soon.

I’ll now invite the operator to open the line for Q&A.

Questions and Answers:

Operator

Thank you. [Operator Instructions] We’ll take our first question from Dan — excuse me, from Derik De Bruin, Bank of America. Please go ahead.

Derik De Bruin — Bank of America — Analyst

Hi. Good afternoon. So Francis, I’m a bit perplexed on the lab expansion comments. Our channel checks and discussions at AGBT in June didn’t suggest that this was happening. So is this more of an issue with your clinical customers not expanding? And how do you know it wasn’t the impact of potential them evaluating competing products? And just exactly how much consumable inventory is there still in the channel? Thank you.

Francis deSouza — Chief Executive Officer

Hi, Derik. So in terms of the lab expansion, what we saw happen in Q2 was a few of our customers that had plans to launch new labs or expanded labs experienced some delays on their own because of their own supply chain issues. Equipment that they were expecting to get for those expanded labs didn’t come in as they expected. And so we saw a few lab expansion plans delayed, some into Q2, into Q3 and then one into Q4 of next year. As you can imagine, we are very close to our customers, so we know the specifics of those lab expansions.

And to be clear, those lab expansions are delayed but still progressing. And so that’s what’s driving the number we talked about, both in Q2 and for the rest of the year. In terms of inventory, what’s playing out is some of our customers that are looking to manage their capital more closely are holding less inventory on their site. They have a lot of confidence in the resilience of our supply chain. And so they’re looking to trim back the inventory levels that they hold on their own site. And so from our perspective, we expect that to play out. It started to play out in Q2.

It will play out a little bit in three and four as well. But in the end, their demand, their activity levels are going to match what we are seeing from the data that we get from monitoring their instruments. And there, the activity and, therefore, demand continues to be very robust. As we said in Q2, the activity levels that we are monitoring on the high- and mid-throughput instruments reflected a growth rate in runs that are greater than 15%. And so as we work through these transitory impacts, we fully expect both demand and therefore orders to more closely match the activity levels that we’re seeing.

Operator

We’ll take our next question from Dan Brennan with Cowen. Please go ahead.

Dan Brennan — Cowen — Analyst

Okay. Thanks for taking the questions. Maybe just a follow-up to Derik’s question and then a related one. So just the magnitude of the second half decline, Francis. So the guidance — the new updated guidance for core Illumina growth suggests kind of flat growth in the back half of the year versus kind of the high teens that you were initially guiding to. So just the magnitude from a few customers, maybe you can just speak a little bit more to just — any more color on that front, just kind of is there a healthy amount of conservatism that you’re baking in here?

Or just kind of how do you — how do we reconcile the magnitude of the cut with a few customers kind of holding back? And then kind of as a related question to Derik’s point, right, are you seeing any delay, whether it be ahead of Chemistry X launching, so customers might be pausing or any impact from some of the competitive noise that’s out there, which I think would be more palatable, I think, for the cut if it was like a pause on — as we’re waiting to evaluate new products? Thank you.

Francis deSouza — Chief Executive Officer

Yes. Thanks for that question, Dan. And maybe I’ll start with the second half, and then I’ll turn it over to Joydeep to sort of size the magnitude of the factors that we talked about. From what we are seeing and what we’re hearing from our customers, the challenges that our customers are addressing are around their lab expansion delays, as I said, related to dealing with their own supply chain for the expansion of their labs and again, tighter management of their inventory levels. And that really were some of the big drivers of the change in addition to a little bit of foreign exchange and so on.

And so what they’re telling us is this isn’t really related to Chemistry X or any competitive issues. In fact, they’re excited to hear about Chemistry X, and they’re looking forward to learning more about it at the Illumina Genomics Forum. But really, what’s driving the change are the factors that we talked about.

And maybe I’ll turn it over to you, Joydeep, to shed some more color on the size of that.

Joydeep Goswami, PhD — Chief Strategy and Corporate Development Officer, Interim Chief Financial Officer

Yes. Thanks, Francis. So I think, first of all, our — Dan, you asked about, is the forecast for the second half conservative? We believe, based on trends we’ve seen, that it’s actually a balanced forecast, right? There’s always upsides and downsides. There are — the factors that we saw in the second quarter we believe will continue into the next of — through the rest of this year. To size them up, approximately 25% of the decline from our forecast, it really is coming from factors such as FX, the faster-than-expected acceleration on the COVID side and some of the declines we have seen in China, which are really more GDP-related effects on the research side of our business in China.

The other 75% or so are related to the factors that Francis referred to, which are really around lab expansion delays due to broader supply chain constraints that are impacting the construction of labs at our customers and them bringing up new assays and instruments and then the impacts we’re seeing from the macroeconomic headwinds on our customers that are causing a temporary reduction in inventory levels and also some capital pushouts.

Operator

We’ll take our next question from Dan Arias with Stifel. Please go ahead.

Dan Arias — Stifel — Analyst

Good afternoon, guys. Thanks. Francis, maybe just back on the consumables side. You’ve talked a lot about the fact that the outlook for sequencing there is good because that work essentially has to be done in order to support patient assessment. So what’s slamming the brakes on purchasing so abruptly? Is it more development on the commercial side related to things like liquid biopsy work? Or are you actually seeing lower-spending, patient-facing institutions, clinical oncology institutions, etc.? And then just a follow-up. Why no preannouncement when Sam left only three weeks left in the quarter? So it seems like a miss since he was well on its way at that point. Thanks.

Francis deSouza — Chief Executive Officer

Yes. So let me take both parts of the question, Dan. So let me start by addressing the consumables and demand point. You’re right. We end up — because we serve clinical customers, a lot of our customers continue to see robust demand. They’re targeting, for example, cancer patients that need their tissues biopsied and then sequenced or ctDNA tests. And that is reflected in the activity levels that we saw in Q2. That even as customers were looking to manage their inventories more tightly, they continued to run their machines hard, right?

So we said, overall, if you look at the run activity on the mid- and high-throughput instruments that we monitor, across our customer base that we monitor, the runs grew 15% year-over-year. But in the clinical markets, that was actually higher for exactly the reasons you talked about that our customers in the clinical markets, especially in areas like oncology, therapy selection testing, which represents for us the largest segment that we serve, that they continued to see robust demand. And that was reflected in their activity levels. Now as we said, our customers are looking to manage their cash more conservatively. So they trimmed back the amount of inventory that they’re holding on their sites, and they can do that as a onetime sort of rebalancing down.

But ultimately, their ordering levels will match the activity levels that they have on their instruments. And so that’s why we expect this impact to play out a little bit in Q2, a little bit in the coming quarters. But then order rates will match, we believe, the actual activity that we’re seeing on their machines. Let me talk a little bit about the Sam point. So when Sam left, we — as we said, he left because of personal reasons, and he needed to be on the East Coast. And that’s what we said when he left, obviously. From our perspective, our quarters tend to be more back-end loaded. And so the impact that I talked about became more clear at the end of the quarter. And so hence, there was no color or commentary at the time when Sam left.

Operator

We’ll take our next question from David Westenberg with Piper Sandler. Please, go ahead.

David Westenberg — Piper Sandler — Analyst

Hi. Thank you for taking the question. Yes. I’m sorry, I’m going to go back to kind of the quantification of the guidance here. If you back out the guidance, it looks like $400 million. FX got worse. I don’t know if you want to quantify that. COVID surveillance, what that number is? I know GRAIL was $20 million and then lab expansion. I mean, is there anything in addition to those factors that maybe you can point out? And then I want to go back to like the instrument — or I mean, the backlog here. You guys felt really good about the backlog exiting the quarter. It seems like maybe that didn’t — those orders didn’t go as expected or fill out as expected. Or what’s going on with that? Thank you.

Joydeep Goswami, PhD — Chief Strategy and Corporate Development Officer, Interim Chief Financial Officer

Yes. So Dave, thanks for the question. Let me reiterate what I said earlier, right? So two broad buckets, about 25% or so of that — of the miss was really around things which included FX, the faster-than-expected decline in COVID surveillance, China and some of the effects — the macroeconomic effects that we are seeing in the second half of the year, which are not related directly to the lockdown, with the slower-than-expected GDP growth that they’re having, right? And then the other bucket, the 75%, really was the two factors, the lab expansion delays, which, again, we expect to see coming back in 2023. So these are comments that we have heard directly from our customers.

And then the second piece was around the slower-than-expected accumulation or restocking of inventory and some capital pushouts from a broader set of customers. Again, as Francis mentioned, we expect these to be transitory. I think in terms of the backlog, I will say that the backlog that — we’re exiting Q2 with a strong backlog of $1.1 billion. This is in line with what we have seen in the previous six quarters. Again, backlog does move around a little bit from quarter-to-quarter as you would expect. But this, again, is very much in line with what we have seen in the past six quarters, which, as you will remember, were pretty strong.

Operator

We’ll take our next question from Julia Qin with JPMorgan. Please go ahead.

Julia Qin — JP. Morgan — Analyst

Hi. Thanks for taking the question. Just two specific follow-ups on the guidance. On NovaSeq, I noticed you took down the pull-through guidance to $1.1 million to $1.2 million. Given you noted there’s still pretty strong volume utilization, are there pricing factors at play for your updated guidance? And then on GRAIL, you took it down by $20 million. So could you — given that NHS seemed to be progressing well, could you explain what the factors are at play there?

Joydeep Goswami, PhD — Chief Strategy and Corporate Development Officer, Interim Chief Financial Officer

So thanks, Julia, for the question. So let me take the NovaSeq pull-through question first. So no, first, let me address — I mean, this is not about pricing pressures. What we — as you know, the pull-through is really an output of a number of factors, right? So shipments in the quarter divided by a number of instruments that we expect to have activated at a certain point in time. Now both these factors played out this quarter in a way that are transitory and we had not expected. So first, although the — as Francis mentioned, right, the number of runs in our instruments were strong due to the inventory deleveraging, the actual number of shipments, which is the numerator of that calculation, was slightly lower.

Also, because we had customers that bought a large number of NovaSeqs in previous quarters and because of some of the lab expansion delays that you heard about, some of these instruments didn’t come online, right? So the denominator, because of the way we calculate pull-through, was inflated. So we do see this pull-through number being lower in this quarter as a result of those two factors. However, as we look forward, given the strong number of runs growth that our instruments are seeing across a broad range of our high-throughput customers and given the strong market factors that are very intensive in sequencing like MRD, like oncology testing and things like spatial and proteomics, we do expect that in the long run, this number will continue to grow.

And then I think you had a second question, which was the GRAIL factor. So a couple of things, right? As Francis mentioned, GRAIL has already proven itself to be a very well-adopted test. It is the fastest revenue growth first year after launch of any screening test on the market ever. So while GRAIL numbers have been somewhat lower than expected from the earlier guidance, it is nonetheless a very strong test, and we see a really strong adoption in multiple hospital systems across the country. So we believe that the test ordering from these systems that have already committed to GRAIL will pick up. But for the time being, I think we remain very optimistic about the quality of the test and its potential.

We’ll take our next question from Tejas Savant with Morgan Stanley. Please go ahead.

Tejas Savant — Morgan Stanley — Analyst

Hey, guys. Good evening.

Francis deSouza — Chief Executive Officer

Sure, Tejas. So in terms of helping our customers as they’re working through the macro challenges, obviously, we remain close to them. The reality is we are core to their business and their revenue generation, and we are a very important supplier to these customers. And so while we can help them in the sense that because of the strength and the resilience of our supply chain, they’re more confident in maintaining less inventory on site that obviously helps them with cash outlays, the reality is they need to continue to service the demand they’re getting because that’s what drives their revenues and their growth and their long-term success.

And so we are not seeing a pullback in terms of activity levels from those customers, again, because we are core to their revenue generation and their success. And we’ll stay — we’re staying close to them. We’re also very staying close to the lab expansion plans and making sure we’re on top of when they expect to get equipment for the labs as they come online. In terms of pricing from our perspective, our thesis continues to believe that there is a huge opportunity to expand the genomics market by continuing to drive the price for high-quality sequencing, highly accurate sequencing down. That thesis continues to hold certainly in the research markets but also in terms of opening up new clinical markets. We’re seeing promising work, for example, happening in areas like cardiovascular disease and neurological disease.

And those will require both very large experiments from a research perspective but also maybe different price points from a clinical perspective. And so we continue to march forward with the idea that part of our mission is to make genomics more accessible by driving costs down. In terms of Chemistry X and the instruments, the way we are thinking about it is there certainly — we’re certainly capable from a technology perspective of making Chemistry X available on instruments that are already on the market. So that is a lever available to us. And as we look at the market, we want to be sensitive to the fact that if customers have bought an instrument that we launched fairly recently, that they may not have gone through their depreciation cycle.

And so we’ll think more about making Chemistry X available on those kinds of platforms. But if it’s been an instrument that’s been on the market for a while and they’ve gone through a depreciation cycle, then there is an opportunity for us to help that market upgrade and not just take advantages of the innovations in Chemistry X, but take advantage of the innovations across all the other technology components, whether it’s optics, for example, of data pads and really deliver transformative new instruments. And that’s how we’re thinking about it.

We’ll take our next question from Puneet Souda with SVB Securities. Please go ahead.

Puneet Souda — SVB Securities — Analyst

Yes, hi Francis. Thanks for taking the questions. So first one is really — could you talk a little bit about, at a high level maybe, about who these customers are? Just trying to understand in terms of, are these customers more COVID customers or oncology customers or genome center customers and their lab expansion plans? Because I think that’s where the challenge is. Because when we look at the life science tools companies, the peer group that you have, some of those companies have delivered very strong growth. They had supply chain challenges in the first quarter.

In fact, supply chain challenges were even more pronounced. And these labs have taken delivery of a lot of these instruments. That’s why peer group companies have delivered strongly. So just wondering what is different here with Illumina instruments or what’s unique about these customers. And then on GRAIL, I mean, you’re pointing out as the fastest adopted test, but at the same time, you’re lowering your guide. So just trying to understand, is there anything — any unique dynamic with certain customers there? Thank you.

Francis deSouza — Chief Executive Officer

Yes. So let’s take both. In terms of the labs, and I think you’re asking about the labs that are delaying their expansion plans, who are they? And you’re saying, look, some of the other life science tools companies haven’t seen that. So I’ll describe them a little bit for you. First of all, it’s a few customers. Second, they’re obviously genomics-focused customers. They run genomics labs. And so you may not see that in the general life sciences tools market, but they — you’re certainly seeing that in the sequencing market. They tend to be customers that are growing. These are the ones that have expansion plans. So they are successful customers. They’re experiencing robust growth.

And in fact, they’re serving markets like oncology, for example, where they see significant increased demand coming and are expecting to — and are building significant labs. And so these are large customers. They are growing customers, and they are customers that are facing significantly increased demand and are looking to expand their labs. Now their genomics labs, and they are primarily — they’re pretty much Illumina customers. And so obviously, we are the ones that ride that cycle with them. And that’s why you’d see it with us. And that’s why you’ll see it as those labs come online. That’s why you’ll see the benefit accrue to Illumina. So that’s the characteristics of the customers that we’re talking about. In terms of GRAIL, it really has been just quite remarkable to see the fantastic growth they’ve had in their first year.

If you look at their first 12 months, so June of — in this June, they just lapsed their first 12 months, they are the fastest revenue growth of any cancer screening test in history. Now that’s quite remarkable, right? They’re also doing a fantastic job in terms of signing up health systems and employers, and I’ll give you another example of just how fast things are moving. So in the last quarter, they fully recruited the 140,000-person trial that they’re running for the NHS. Now typically, a trial like that would take years to fully enroll. And the NHS working with GRAIL was able to do that in 10.5 months.

That gives you some sense of just the acceptance, the hunger in the market, the demand in the market for just such a breakthrough test, right, the fact that it can identify 50 cancers across all stages. And people are starting to get a sense of the results that they are making it into the market. Now what we’re looking at — now even with that to our growth base is we’re looking at the rest of the year, and we’re looking at the ramp-up that’s happening in some of the health systems that have signed up and some of the employers, the GRAIL team has trimmed back some of their estimates for the rest of the year. That doesn’t take away, again, this is the fastest-growing cancer screening test we’ve ever seen in history.

We’ll take our next question from Kyle Mikson with Canaccord. Please go ahead.

Kyle Mikson — Canaccord — Analyst

Hey, thanks for taking the question. Just a few on the guidance. So I was just curious about components of instrument revenue growth for ’22, 1.5% year-over-year. Maybe, Joydeep, can you talk about expectations for placements versus orders versus pricing? Maybe pricing is locked in or not locked in at this point. Just given the backlog commentary, it was very strong kind of like entering the year and recently. Just how is that trending recently and going forward? And kind of relatedly, the year-over-year decline in mid-throughput shipments in 2Q, I mean, I hear you on China and the other factors. But any chance that’s partially due to the platform evaluation process as these new vendors enter the market or at least make some noise? Because obviously, these large clinical labs already test-driving these products. So it’s just worth asking. Thanks.

Joydeep Goswami, PhD — Chief Strategy and Corporate Development Officer, Interim Chief Financial Officer

Yes. Thanks, Kyle. So let me start with the 2Q piece on the mid-throughput, right? So as I mentioned right there, the orders for mid-throughput really were very strong, right? So we saw continued interest and strong orders for NextSeq 1000/2000, this is our latest platform on that, pick up considerably. And while there was a temporary supply chain issue at our end, which prevented us from delivering these orders in 2Q, they have subsequently been delivered already in this quarter. So we are very optimistic, and we see very, very strong demand and interest in our mid-throughput platform, both on our research and our clinical customers. On the full year, so a couple of things, right?

So you start with NovaSeq first, right? So we’ve had a strong first half of the year. Our orders for the first part — first half of the year were up 30% year-over-year and, as we mentioned, right, 23% growth in the second quarter. Now this is for a platform that has — that’s now six years from launch, right? So we see extremely strong, unprecedented demand even on the back of a very strong 2021, and we’re excited about that. Remember also that these instruments have — most of these instruments have now been deployed. We expect now that the pull-through on consumables on these instruments will come and will continue to accelerate in subsequent quarters and years. So we feel very good about our portfolio both in the high-throughput and the mid-throughput segment.

We’ll take our next question from Patrick Donnelly with Citi. Please go ahead.

Patrick Donnelly — Citi — Analyst

Hey guys, thanks for taking the question. Francis, maybe one for you just in terms of kind of the operational spend that you guys are doing. You obviously kind of talked about the op margin pull down in the back half. Can you talk about how you’re balancing some of the growth investments with also being mindful of kind of insulating the margins, protecting the bottom line? Obviously, you have Chemistry X and Infinity coming up. I would assume you’d want to invest in kind of the launches there. So maybe just talk about, again, kind of that balance of investing for growth and, at the same time, kind of realizing with things slowing, you need to protect the bottom line a bit and where you’re pulling back and where you’re pushing forward. Thanks.

Francis deSouza — Chief Executive Officer

Yes. Sure, Patrick. So obviously, with the revised revenue outlook for the year, we are taking a look at our spend and exactly as you said, doing that balance. On the one hand, we’re looking for areas where we can contain costs. That means pulling back on discretionary items, for example, like travel and other discretionary spend. And we’re also prioritizing the hiring that we’re doing. And so there are some hires that we will put off because we don’t think it’s essential to do right now. So the team is absolutely doing that work. Having said that, we’re also protecting our innovation road map as well as essential hires in the other parts of the company as we scale the business.

We have very ambitious product plans, as you know, and we’re going to continue to protect that road map because that’s what drives the success of our customers and our long-term success. And that’s what creates the long-term shareholder value in the company. So that’s the balance we’re doing. We’re protecting the innovation road maps. We’re protecting activities that drive that long-term shareholder growth, including things like capacity expansions, IVD capabilities, commercial expansions in targeted markets and sort of maintaining that balance.

Joydeep Goswami, PhD — Chief Strategy and Corporate Development Officer, Interim Chief Financial Officer

Yes. I would also add, we continue to have productivity improvements on our gross margin side as well, right? So that’s, of course, despite the reduced volume that we have seen this year, some of those improvements are contributing to increased gross and operating margin as well.

We’ll take our next question from Vijay Kumar with Evercore ISI. Please go ahead.

Vijay Kumar — Evercore ISI — Analyst

Hey guys. Thanks for taking my question. Francis, maybe a two-part question for you. Your guidance for the back half, it implies 1% growth. You just did 3% in 2Q. Are you — is the guide assuming things to worsen from 2Q levels? Because if I understood you, some of these are temporary factors. If I look at your inventory on hand, I don’t think your customers stock up to 12 months. So shouldn’t some of these factors were — how conservative is this guidance for the back half? And on Chemistry X, I think we’ve heard a 30% price cut, 20%, 30%, somewhere in that ballpark. Does it have any implication to — of revenue growth for fiscal ’23?Thank you.

Francis deSouza — Chief Executive Officer

Yes. So thank you, Vijay. Let me start with the first part of the question, which is Q3 guidance, sort of what’s driving that number. And so I’ll talk about some of the factors that are driving that number. If you — and if you normalize the impacts that I’m talking about, the growth is higher, and I’ll come back to that as well. So some of the factors that are driving it are the headwinds that I talked about. There is a headwind around COVID surveillance demand pulling back. That’s playing out in Q3 as well. There’s obviously a foreign exchange headwind and the tough compare with the UK Biobank that concludes in Q3. So that’s another factor playing out in Q3.

We also expect the continued slower GDP growth in — China growth, and that will play on us. And then the two factors that I talked about, sort of inventory management and the lab expansions, right? So those are some of the factors that we factored in, in giving the guide for Q3. And obviously, if you normalize for those factors, then you’re looking at a significantly higher growth rate in Q3.

We’ll take our last question from Jack Meehan with Nephron. Please go ahead.

Jack Meehan — Nephron — Analyst

Thank you. Good afternoon. Francis, I have a two-part question for you on GRAIL. So the first is just given the prolonged regulatory uncertainty here, is there a point where you could choose to walk away? What’s your conviction level on getting this done? And then second off, that obviously now isn’t the most accommodative environment for capital markets activity. So in a scenario where you might have to spin GRAIL out, how would you fund the ongoing operations? If I look at your balance sheet, after the BGI payment and the fine you have earmarked to the European Commission, you have roughly $550 million of unrestricted cash. So just talk about, if you got to that, how would you finance a spin if it ends up there?

Francis deSouza — Chief Executive Officer

Yes. So I’ll start by saying that our focus is going to be continually to focus on and think about the things that create the most long-term shareholder value. And as we embarked on this process, as you said, we clearly felt that combining GRAIL and Illumina creates the most long-term shareholder value. I’ll give you an example, right? So even on their own largely, the GRAIL team was able to achieve the fastest 12-month ramp of any cancer screening test in history, as we’ve said. And I imagine what that could have been with the power of Illumina behind it. And if we think forward, what could we do if we were able to take that test into markets like Europe and Asia and Africa beyond the plans that GRAIL could have?

And so that’s sort of what drove our thinking. Having said that, we’re going to continually assess as we work through this process, what are the right next steps? And there obviously are a set of nodes on the decision tree that would lead us to either spinning out GRAIL because the regulatory process doesn’t go our way or contemplate other forms of exits, whether its dividend in the back or — and so we’re going to continue to assess that as we work through the regulatory process. In terms of your question around funding the operations, that’s absolutely going to be a consideration as we contemplate the options on how we have to spin GRAIL out, right?

So the idea is that what you’d want to do is make sure that you protected the asset value to allow GRAIL to continue to execute on its mission. And so that means making sure that it’s capitalized so it can continue to be successful as well as it has access to future capital that it will need for its own expansion plans. And that’s going to be a combination of Illumina but other shareholders, too, potentially and other people who will inject capital both maybe at the time of divestiture but then over time as well. And so those are some of the considerations as we think about what a divestment would look like, how do we — how would we set it up to be successful. And what’s the path for it to continue to be successful? Obviously, those are not decisions that we’re making today, but those are some of the considerations that would go into it.
