Jay Flatley - President and CEO
Thanks, Rebecca, and good afternoon, everyone.
To begin today, I will provide an update on the state of our business and markets, before turning to our commercial progress.
Marc will then review our fourth-quarter financial results and our guidance for fiscal 2013.
Despite uncertainty around sequestration and the general macro environment, our business has continued to accelerate.
Q4 shipments were strong across all geographies, and revenue grew 24% year-over-year to $309 million.
Shipments to the Americas grew 20% year-over-year, and European shipments were up 26% over the same period.
Shipments to Asia continued be strong with year-over-year growth of 12%, including 30% growth in greater China.
While the NIH funding environment remains uncertain in light of a potential sequestration, our customers continue to display stable ordering patterns.
We believe this is due in part to a larger percentage of NIH funds being granted to sequencing-based research.
Additionally, the European and Asian funding environments remain stable, and Asia may even improve slightly in light of Japan's recent stimulus announcement.
Despite these positive trends, we remain focused on diversifying our customer base.
In fiscal 2012, approximately 30% of revenue came from non-academic and non-government segments.
Our goal is to increase this to approximately 50% of revenue over the next five years.
We believe this is possible as we accelerate the penetration of our technology into applied markets, including the clinical, translational, consumer, forensic and agricultural segments.
I'd like to now turn to the specifics of the Q4 results.
Total microarray revenue increased 4% year-over-year due to the impact of BlueGnome, while organic microarray revenue declined slightly.
Order volume grew sequentially as a result of demand for the Infinium Omni arrays and significant interest in the recently launched Infinium HumanCore arrays.
In the first two and a half months since launch, we received orders for 325,000 samples of the HumanCore arrays, which we expect to begin shipping this quarter.
As an illustration of the high activity level that remains in the array market, in Q4, we shipped over one million samples worth of arrays across all of our array-based product lines, including Infinium, GoldenGate and Veracode.
Turning now to our sequencing business, total sequencing revenue grew 35% over the fourth quarter of 2011, driven by strong demand for consumables.
In fact, in the fourth quarter, sequencing consumables grew 56% year-over-year, due to higher utilization per instrument, as well as growth in both the HiSeq and MiSeq installed base.
Our sample prep business continued gain share in the quarter and contributed significantly to sequencing consumables growth.
Nextera and Nextera XT sample prep kits had a particularly strong quarter, and the TruSeq demand was strong from translational and clinical customers.
In addition, we are further expanding our portfolio with the launch of innovative sample prep solutions that streamline work flows and decrease turnaround times.
In the first quarter, we expect to launch the Nextera Rapid Capture Exome kit, which will enable the fastest exome enrichment work flow for use on both the HiSeq and the MiSeq platforms.
These kits will make the work flow 70% faster than the current solution.
We also plan to release TruSeq Targeted RNA kits this quarter, targeting the [mid-flex] real-time PCR market, which we estimate to be a $300 million market today.
Finally, I'm pleased to announce we've begun shipping our TruSeq DNA PCR-Free kit, which provides industry-leading genome coverage, high accuracy in identifying variants, and the ability to sequence challenging regions of the genome.
We also continued to deliver dramatic enhancements to our SBS chemistry.
Our latest technology innovations demonstrate the scalability of SBS by enhancing cluster density and read lengths.
Our novel ordered array technology overcomes typical statistical limits to significantly increase cluster density and the number of reads per flow cell.
This breakthrough development will increase sequencing output, enhance counting applications, and reduce turnaround time through more efficient image processing.
We expect to begin field testing this technology in Q3 and have it incorporated in our first kits around year-end.
We also recently announced the acquisition of Moleculo, which gives us access to a proprietary technology for assembling phase reads of more than 10 kb and an extremely low error rate of Q50 or better.
Through sample prep and bioinformatics, researchers can create a completely phased genome in four days with only 30G of incremental sequencing.
This will directly benefit approximately 10% of the NGS applications today as well as a portion of the capillary market.
We plan to launch this in our services business during the second quarter with kits available toward the end of the year.
We will further expand the capability of the HiSeq platform in the second half of this year, with the launch of new kits to sequence up to 300G in approximately 60 hours.
This expanded capability will come solely from enhancements to reagents and software.
Sequencing instrument revenue increased 6% compared to the fourth quarter of 2011, with MiSeq instrument sales demonstrating significant growth year-over-year.
Additionally, ASPs remained strong despite the ongoing success of our trade-in program.
Interest in the MiSeq platform also widened since we laid out the updated product road map at ASHG, including a path to 15G of output.
Based on field commentary, our competitive position has strengthened, and we're optimistic that strong ordering patterns will persist.
During the fourth quarter, we received more than 300 MiSeq orders, which exceeded our manufacturing capacity.
This strong order trend, along with MiSeq winning 80% to 90% of head-to-head competitions, provides evidence that we had more than 50% market share this quarter.
Customers are choosing MiSeq as it consistently delivers higher output and better data quality along with the easiest work flow.
We believe this end-to-end work flow, including back-end informatics, streamlined data analysis and data sharing features via BaseSpace offer the most comprehensive solution for desktop sequencing customers.
Successful launch of the HiSeq 2500 in October illustrates the tremendous value customers find in the HiSeq platform.
We now expect to upgrade around 35% of the existing HiSeq installed base.
It will take us most of 2013 to complete this upgrade program as less than 10% of the installed base was upgraded during the fourth quarter.
The HiSeq platform is now also enabled to stream data to BaseSpace.
The breadth of analysis functionality being delivered by BaseSpace apps is growing every of month, and we expect full e-commerce roll-out in the second quarter.
Our FastTrack services business shipped more than 2500 genomes in the fourth quarter, or close to 3 times the number shipped in Q4 of last year.
Demand grew consistently through 2012, and in total, the Illumina genome network received orders for approximately 13,000 genomes.
Today, interest in sequencing services remains high, including preliminary talks with large hospitals and governments that hope to sequence significant numbers of individuals.
To fill the demand for sequencing services, we've added significant new capacity to our San Diego facility and will open a new lab later this quarter in our Hayward location.
This facility, along with improvements to our existing infrastructure, will provide the capacity to sequence approximately 30,000 genomes this year.
Moving on to our clinical business, we recently signed a definitive agreement to acquire Verinata Health, a leading provider of noninvasive prenatal tests, or NIPT, for the early identification of fetal chromosomal abnormalities.
This acquisition will build on our earlier acquisition of BlueGnome, adding another building block to our portfolio and moving us toward our goal of leading the genetic revolution in reproductive health.
These acquisitions, combined with our internal carrier screening inside our genetics programs, provide us with a solid foundation to accomplish this goal.
With this acquisition, Illumina's uniquely positioned to enable the growth of the NIPT market.
We believe Verinata possesses foundational IP and has the most comprehensive noninvasive prenatal tests.
Our strategy will be to leverage these strengths by licensing Verinata's intellectual property, and once we have compiled the necessary data, submitting the tests for regulatory approvals.
We believe an IVD test will significantly expand the global market, enabling all test providers to be successful in this field.
Verinata has signed an exclusive US distribution agreement with PerkinElmer to drive adoption of the verified prenatal test.
We're excited about this announcement and look forward to participating in this partnership once our acquisition of Verinata has closed.
I'm pleased to report that we also submitted our first two sequencing products to the FDA for 510 k clearance in the fourth quarter; the MiSeq Dx system and the cystic fibrosis full gene sequencing assay.
We believe the CF assay is differentiated from current test offerings as it will sequence the entire CF gene while also identifying a group of specific CF variants.
We're pleased with our execution in 2012 and our outlook for revenue growth in 2013 and beyond.
To ensure this momentum translates into strong long-term revenue growth, we will continue to make incremental investments in our core business in addition to investing in Verinata and BlueGnome.
We will focus our 2013 organic investments in three key areas.
First, while the competitive dynamics surrounding our sequencing platforms are strong, today we're not able to match the geographic reach of our competitors.
To improve this position, we plan to add more than 50 additional sales reps over the course of the year.
This investment will add to growth in the near term and create significant leverage in the years beyond.
We also plan to invest incrementally more in research and development this year due to the richness of our portfolio opportunities.
Our goal is to remain on the leading edge of technology by introducing even a greater number of new products, investigating new chemistries including Nanopore, and working to provide solutions to customer bioinformatic challenges.
Lastly, we're investing in the necessary infrastructure enhancements to support a $2 billion company.
We recently began two new projects that are projected to cost approximately $10 million in 2013.
The first multi-year project being led by Marc Stapley is focused on improving our global business processes via enhancements to our ERP system as well as the related systems and processes necessary to support our growth projections.
Christian Henry is leading a second project, which is focused specifically on manufacturing, planning and inventory management.
Success of these programs will improve our order fulfillment performance and ultimately our gross margins as we more efficiently meet customer requirements.
Part of this infrastructure build will be particularly focused on diagnostic and clinical customers.
While nascent today, the clinical adoption of NGS is set to revolutionize healthcare.
To this point, a number of organizations have recently published guidelines on the use of NGS in the clinic, including the American College of Medical Genetics and Genomics, the Association for Molecular Pathology, and the CDC.
These groups have cited the increased rate of clinical adoption of NGS as the catalyst for guidelines in an effort to ensure patients have access to high-quality data and interpretation.
We believe that by making these strategic investments, we will accelerate the adoption of sequencing technologies more broadly into all of our end markets and position ourselves for strong, long-term revenue growth.
I'll now turn the call over to Marc, who will provide a detailed overview of the fourth quarter results.
Marc Stapley - SVP and CFO
Thanks, Jay.
During my section of today's call, I will review our fourth-quarter financial results before providing commentary on our guidance for 2013.
With respect to Q4, as Jay described, our positive momentum continued and led not only to the fifth quarter of sequential revenue and EPS growth, but also our strongest quarter ever.
Impressive MiSeq instrument sales, as well as demand for sequencing consumables and all genome services, generated record revenue of $309 million, an increase of 24% year-over-year.
Our BlueGnome acquisition contributed revenue of approximately $7 million in the quarter, which is higher than our original estimate due to the early success of the ongoing integration.
Revenue for 2012 was $1.15 billion, which represents an increase of 9% over 2011, reflecting primarily consumables growth year-over-year.
Instrument revenue for the fourth quarter was $80 million, which is flat compared to the fourth quarter of 2011.
HiSeq shipments were down slightly year-over-year as was the demand for micro array instruments, but this was offset by strong demand for our MiSeq benchtop instrument.
Consumable revenue in the quarter was $196 million, an increase of 36% compared to the fourth quarter of 2011, primarily due to higher demand for sequencing consumables and the impact of BlueGnome.
Consumable revenue represented 63% of total revenue, up from 57% in Q4 of last year and up slightly sequentially.
As we build out the sequencing installed base, consumables sales continue to climb, and this contributes to the improved mix year-over-year.
For the full year, the average consumable pull-through was approximately $320,000 for HiSeq and approximately $50,000 for MiSeq.
Due to the fact that seasonality and the timing of purchasing cycles can cause significant quarterly fluctuations in the pull-through rate, going forward on a quarterly basis, we plan to give qualitative commentary comparing against our projected annualized quarterly levels.
These projected ranges of $300,000 to $350,000 for HiSeq and $45,000 to $50,000 for MiSeq.
Services and other revenue, which includes genotyping and sequencing services, as well as instrument maintenance contracts, was $30 million for the quarter, a 54% increase year-over-year.
This was driven largely by the significant number of genomes processed in the quarter, as well as the ongoing growth in our extended maintenance contract associated with the growing instrument installed base.
Turning now to gross margin and operating expenses, I will highlight our adjusted non-GAAP results, which exclude non-cash stock compensation expense, headquarter relocation expense and other items.
I encourage you to review the GAAP reconciliation of non-GAAP measures included in today's Earnings Release.
Our adjusted gross margin for the fourth quarter was 68.5%.
This compares to 70.5% in the third quarter of 2012.
The sequential decline in gross margins was due to non-recurring part replacement costs associated with our extended warranty services, inventory reserve, manufacturing variances and a small impact from BlueGnome margin dilution.
Admittedly, we were disappointed with this result, but are positive that the programs we already have in place, which Christian and I are sponsoring, will help ensure we see a gradual improvement in gross margins going forward.
These programs include the inventory planning and management system, as well as the global business process program that Jay mentioned earlier, in addition to discrete programs focusing on reductions in cost of goods sold.
Adjusted research and development expenses for the quarter were $48 million or 15.4% of revenue compared to 15.9% in the third quarter and up slightly over the 15% of revenue in the fourth quarter of last year.
The sequential increase was primarily due to headcount additions, as well as the impact of BlueGnome.
Adjusted SG&A expenses were $62 million or 19.9% of revenue in the quarter.
This is compared to the 19.5% of revenue in the third quarter, and a decline from the 20.1% of revenue in the fourth quarter of 2011.
Legal fees associated with the Complete Genomics bid as well as the Verinata and Moleculo acquisitions contributed to the slight increase over Q3.
Adjusted operating margins were 33.1%, compared to 35.1% in the third quarter, due to lower gross margins as well as higher SG&A expense.
On a year-over-year basis, operating margins contracted somewhat due to lower gross margins as well as higher research and development expense.
In the fourth quarter, we recognized approximately $1.6 million of adjusted other income, which included interest income recognized on a recovered loan that was previously impaired.
Our non-GAAP tax rate for the quarter was 28.9%, compared to 35.3% in the fourth quarter of last year.
The Q4 tax rate benefited from the transition of manufacturing to Singapore, exceeding our full year internal expectations, but did not benefit from the 2012 R&D tax credit, which was enacted in January and will therefore be recognized in the current quarter.
Non-GAAP net income was $57 million for the quarter, and non-GAAP EPS was $0.42.
This compares to non-GAAP net income and EPS of $44 million and $0.35 respectively in the fourth quarter of 2011.
These results were slightly better than we projected at the time of the JPMorgan conference, with lower than anticipated gross margins being more than offset by the tax rate coming in below our forecast, both items being updated subsequent to the conference as part of our normal close process.
We reported GAAP net income of $72 million or $0.53 per diluted share in the fourth quarter, compared to $11.7 million or $0.09 per diluted share in the prior-year period.
Current period results include the sale of our minority investment in DeCode Genetics to Amgen, which resulted in the pre-tax gain of $48.6 million.
Additionally, we incurred $4 million of ongoing expenses related to Roche's unsolicited tender offer as well as a $3 million charge associated with the relocation of our headquarters.
This charge is primarily due to a delay in the anticipated sublease of our prior headquarters.
During the quarter, we generated cash flow from operations of $79 million.
Capital expenditures were approximately $17 million, resulting in $62 million of free cash flow.
DSO decreased to 63 days compared to 69 days last quarter, and we ended the quarter with $1.35 billion in cash and short-term investments.
During the quarter, approximately 496,000 shares were repurchased for $25 million under our previously announced repurchase program, leaving slightly more than $165 million of authorization remaining.
Before looking ahead to 2013, I'd like to clarify that all guidance estimates include the impact of the Verinata transaction, which we do expect to close shortly after the satisfaction of regulatory approvals.
For fiscal 2013, we are projecting total Company revenue growth of approximately 15%, and full year non-GAAP EPS of $1.55 to $1.62.
Included in these projections are the following assumptions -- Verinata dilution of up to $0.20; 70% gross margin; the impact of the investments Jay mentioned earlier; stock compensation expense of $115 million; assuming the current stock price full year weighted average non-GAAP diluted shares outstanding of 134 million; and a full year pro forma tax rate of 31%, which includes the benefit of Singapore manufacturing, the 2013 US R&D tax credit, and in Q1, the catch-up benefit from the 2012 R&D tax credit.
To conclude, we have made significant progress this quarter with our market-leading instruments, and customer interest continues to be strong.
Our installed base in both the [high-sensitive vestile] markets has continued to grow, and our new product introductions have been well received.
In addition, we have furthered our diagnostic strategy with an acquisition in one of the fastest growing clinical segments.
We believe that our planned investments are critical to ensure that we efficiently deliver the most innovative and highest-quality solutions to both our existing and new customers, enabling strong revenue growth in 2013 and beyond.
Thank you for your time, and we'll you now open up the line for questions.
Operator
(Operator Instructions)
Tycho Peterson, JPMorgan.
Tycho Peterson - Analyst
Maybe just first question on the gross margin guidance.
Can you maybe talk about some of the gives and takes to get to that 70%?
Obviously you talked about some of the investments that are being made on the IT front.
Can you just talk about where you're going to get some of the leverage?
Marc Stapley - SVP and CFO
Yes, hi, Tycho.
Some of the leverage is going to come from -- we mentioned we had some nonrecurring items in the fourth quarter, so obviously we're doing a lot to address that as well.
So that will help us in the first quarter.
The consumable mix will continue to help us.
From the headwind standpoint, as I've always said, as our services business grows as well, that's dilutive to margin, and then the Verinata acquisition itself will be somewhat dilutive in the quarter when that closes.
And then the other is pricing.
We think we have leverage there including consumable pricing.
Remember, the pricing increase that we put in place during 2012, some of that was deferred based on standing orders that were placed.
The effect of that will come through in the first quarter, in addition to, in the second quarter, the new pricing increase -- relatively modest pricing increase we talked about previously.
Tycho Peterson - Analyst
Then just a follow-up on Verinata.
You talked about, obviously when you announced it, the uncertain IP landscape.
Could you maybe talk to time lines to which you think you could get some resolution there, and then are you still looking at acquiring additional content to help kind of build that out as you partner with Perkin?
Jay Flatley - President and CEO
Well, intellectual property, as you know, Tycho, is always an area of uncertainty in terms of timing.
Our goal certainly is to enter into discussions with all the players and all the owners of various intellectual property in the field and see whether there's the potential to sort this out in a way that's rational for everyone.
We're not sure that's the case, but we're hopeful that it is.
I suspect we'll have a first shot at that sometime in the next quarter.
If we're not able to do that, then these various litigations will proceed along the traditional legal tracks which often take multiple years.
With respect to content, I'm not sure what your question was directed toward exactly.
Tycho Peterson - Analyst
You had talked about maybe adding on Turner syndrome Triple X, other content that could be kind of bundled with this.
Jay Flatley - President and CEO
I see, yes.
So the existing Verinata test includes the three trisomies, the 21, 18 and 13, and it also includes today the typical sex chromosome abnormalities.
That's where the test will stay for some time.
But you did see publication shortly after we announced the transaction, I believe it was Thursday of the week of JPMorgan.
Publication by scientists at Verinata talking about the ability to use this test to detect sub-chromosomal abnormalities.
So that's something to focus on in the future, but nothing we're prepared to comment on specifically as to timelines.
Tycho Peterson - Analyst
Thank you very much.
Operator
Doug Schenkel, Cowen & Company.
Doug Schenkel - Analyst
You guys have been obviously pretty active with M&A over the past few months, so I guess just a few related questions.
First, would you be willing to break out how much of the growth that you expect in 2013 is organic versus inorganic revenue and how much of that's Verinata?
I guess the second question would be -- mathematically, it seems like you're layering on at least $40 million to $50 million in operating expense onto the P&L via the Verinata transaction.
Is that all Verinata-specific, or would you expect some benefit from that spend as you think about really broader clinical initiatives that you're targeting over the next few years?
And then finally, any update on how discussions are progressing with some of Verinata's competitors that are existing Illumina customers?
Jay Flatley - President and CEO
Okay.
Let me give a shot at those things.
To the first part of the question, we're not going to decompose the revenue any further than we've done during the script, Doug, so we're not going to give a lot of further insights into that.
I think you can, based on some of the guidance we gave about dilution, back into some of the Verinata numbers if you work at that.
With respect to the incremental expenses in Verinata, there is going to be some carry-over into other parts of the business.
Certainly one of the things we're going to be doing quite actively this year and next is investing heavily in the clinical trial work necessary to get an IVD product into the market.
So that's over and above the traditional headcount expenses that you would inherit, and that's all budgeted into the numbers that we've included for the dilution.
There are some areas where we'll be able to work with them in [clin reg] and things like that where it may give us the opportunity to not spend as much as we might have in San Diego.
And clearly the program will be integrated very tightly with what we're doing at BlueGnome because particularly as we get into sub chromosomal analysis, there's a very clear intersection with what we're doing with PGD and with cytogenetics.
So those programs will become more integrated as we move forward.
With respect to discussions with the other players, we've obviously met with them, and over the next I'd say month or two, we'll be in significant discussions with them about the various interests that they each have in this field and working forward to address any concerns they might have about their supply agreements, et cetera.
Doug Schenkel - Analyst
Thanks for all that.
One real quick one.
You again acknowledged really the commercial reach disadvantage that you say you have in benchtop sequencing, and that's part of the incremental spend that you guys outlined in your prepared remarks today.
But do you believe the fact that you received 300 orders for MiSeq in Q4 is at all a sign that this disadvantage is dissipating?
Jay Flatley - President and CEO
We do think we've made significant progress already, both in getting word of mouth from the first users of MiSeqs who love the instrument, are talking to others in the market and the rate of publications is ramping up, so there's a bit of a viral effect that's beginning to take hold with respect to MiSeq.
We still remain challenged in some of the more distant geographies.
By that I mean places where you wouldn't normally have a direct sales organization, and so we do plan to beef that up, both through addition of some improved distributor networks, but also just adding in people.
And those would go into typical or customer sites that we wouldn't normally call on.
So I think there's more to be had here, and the 50 incremental sales reps that we plan to add we think will be enough to get us to the next level.
Doug Schenkel - Analyst
Okay.
Thank you.
Operator
Derik De Bruin, Bank of America.
Derik De Bruin - Analyst
Could you just give us a general feel for the -- how many MiSeqs you placed in 2012?
And I'm just trying to get a sense for where we are in the roll-out and the market opportunity.
What do you think is the potential for the penetration of that?
And then I also want to sort of flip that over to HiSeq.
I'm just trying to get what's sort of embedded in 2013 for your instrumentation expectations?
Jay Flatley - President and CEO
I'm sorry, Derik, I missed the last part of your question.
Derik De Bruin - Analyst
I'm just trying to get a sense -- when we look at the 2013 guidance, what should we be thinking about instrument growth versus consumables growth?
Jay Flatley - President and CEO
Well, the last data point that we gave on MiSeq was when we passed through the 1000 unit number.
And so that's the latest update we've given on the installed base, and you can assume that we're significantly above that now.
We did get 300 orders as we mentioned in the fourth quarter.
We didn't ship that many because we also stated that that 300 unit number exceeded our production capacity during the quarter and obviously therefore exceeded our forecast in terms of what we expected.
So the momentum around HiSeq is really quite good.
I think you can use that 300 as a benchmark to make your extrapolation on what you think that placement rate might look like through the course of this year.
So far we're continuing to see growth in MiSeqs.
I don't think I would say that every quarter we're going to continue to grow the order rate.
At some point, that's going to flatten out some.
HiSeqs, I think you can roughly think about that as being in the ballpark of flattish on a units basis, although varying a little bit quarter to quarter.
Christian Henry - SVP & General Manager, Genomic Solutions
I think the one thing about HiSeq, though, Derik, is that the 2500 really gives us an opportunity as an upsell because it's typically at a higher ASP than the 2000, and so even though the -- and many customers are buying -- are opting for the 2500 over the 2000.
So on a revenue basis, that really helps us.
Jay Flatley - President and CEO
Yes.
In fact we saw in the fourth quarter a significant uptick in ASP because of the mix towards 2500.
Derik De Bruin - Analyst
Thanks.
That's really helpful.
So Doug sort of asked the one question on the competition for Verinata.
I'm going to ask the competition on the services side of the business with BGI now going to be acquiring Complete Genomics, how do you look at that relationship going forward, and have you had any indication from customers about what they're thinking about that?
Jay Flatley - President and CEO
I think it's a little early to tell because they don't own them yet, so I don't think what we've seen in the marketplace is reflective of any different strategy or new strategy on the part of complete genomics.
Once the transaction's complete, we'll obviously be watching for that.
Our goal is to continue to make BGI a very successful customer and have a successful relationship with them.
Once they complete the transaction, we will be having a series of meetings with them to sort of understand where they want their supply agreement to go with us, and that agreement is up for renewal in the April time frame.
So it's quite timely, actually, so we'll be sitting down with them shortly to go through all that.
Derik De Bruin - Analyst
Great.
I'll get back in the queue.
Operator
Amanda Murphy, William Blair.
Amanda Murphy - Analyst
So I had a question on the ordered arrays that you'd talked about at JPMorgan.
You talked about the arrays providing meaningful benefits on the HiSeq.
I'm curious what exactly that means in terms of performance for customers.
And ultimately, could that translate to a bigger benefit on the MiSeq than perhaps initially?
Jay Flatley - President and CEO
We haven't given out the exact specs yet, Amanda.
And the reason we haven't is because we haven't decided exactly how we're going to formulate the kits yet.
It's not that we don't have the answers.
It's really a marketing question now about how we actually design the particular flow cells that we'll put in these kits.
On all of the sequencing products, you'll have a direct linear relationship between the cluster density that we have traditionally extrapolated now to the number of ordered features.
So whatever that increase is, you'll increase that number of tags and therefore for counting applications such as expression, you'll have that direct relationship.
If there's 1.5 times as many tags -- 1.5 times as many features, you'll have 1.5 times as many tags for expression.
With respect to the amount of sequencing output, it's a little more difficult because it will relate to a couple different factors.
One is to the optical resolution of the particular instrument, which may help dictate the exact pitch or the distance between the order features, and that may wind up being different on the different flow cells for the different products.
And it is also conflated with the different read lengths.
So if we're changing read lengths on these instruments as well, we have to be a little bit cautious about quoting numbers because some parts of the overall increase in output will come as a result of read length versus density increase on the flow cells.
So that's a long-winded answer to basically say you're going to have to wait a little while longer until we actually determine the specific kit configurations that we're going to launch and what the impact is.
Christian Henry - SVP & General Manager, Genomic Solutions
I do think the one thing that's really interesting to think about is the quality of the reads today at 150, 250 base pairs is really high.
And with the ordered arrays, you may make tradeoffs to decide, hey, I want to stay at 150 or 250 base pairs and get an improvement in density, or you may want to go out -- we may decide to optimize on the longer read length with a wider pitch so to speak to keep the performance of the -- whatever that particular flow cell product in a specific range.
So it gives us a lot more flexibility.
Amanda Murphy - Analyst
Got it.
And then the other thing I was going to ask is.
I guess at a high level, and obviously you're not going to talk too much about your pipeline, but just one of the take-aways I had given your recent announcements is that there's clearly a lot more room on the SBS chemistry.
You've mentioned some of the read length improvements that you can make, et cetera.
I'm just curious how to think about that in terms of just the capacity of the industry, where that's at currently and sort of the propensity for customers to adopt technology going forward.
Obviously not saying you're going to have a new platform or anything like that.
Just thinking about how much more room you have on the SBS chemistry versus new products you may or may not be introducing in the long term.
Christian Henry - SVP & General Manager, Genomic Solutions
By capacity industry, I presume you meant the market's ability to absorb new technology or greater output?
Amanda Murphy - Analyst
Exactly.
Yes.
Jay Flatley - President and CEO
Yes.
Well, we think, and we've thought this for a long time, that the actual demand for sequencing in any near term horizon really is an insatiable demand.
I think if you reflect back onto the V3 issues we had in 2011, what we really did there is we created a temporary discontinuity in the market because the market didn't have a channel of samples ready and they had to change the way they ran the instruments, so partly that's a reflection of a lesson we learned in terms of how to make sure we introduce these technologies in more piecemeal ways.
But I don't think it's reflective of the capacity of the industry.
That capacity is really only governed by how many dollars there are out there allocated towards sequencing, and if we can make greater capacity for the same dollars, that capacity will get absorbed.
The goal we've had always is to continue to drive down the price of sequencing because we think it enables new markets and makes the overall dollars that are coming into the market much, much larger as a result of enabling those new segments.
And we're going to do that in lots of different ways.
Part of is by segmenting the market more so there will be over the next few years potentially more systems that address more targeted segments of the market.
You could imagine now that we're involved in the NIPT market more directly, that we have the ability to begin to think about how do we optimize technology for specific kinds of tests, and ultimately, we'll decide whether that's an economic decision that makes sense for us to more closely design an instrument for a family of particular tests.
That test, for example, uses only 25 base reads in most of the applications, so it's slightly different than a general purpose instrument.
So I think the way to think about this is that we will create more variations of the instruments over time that will be more specifically tailored to particular market segments.
Amanda Murphy - Analyst
Got it.
Thanks very much.

Ross Muken - Analyst
So on the new product side, post JPMorgan, you guys had a whole slew of announcements on both sides of the business.
Where did you see the most interest in terms of some of the advancements that you had both on HiSeq, MiSeq, and what was the response to the Moleculo concept?
Jay Flatley - President and CEO
I think people probably expected us to continue to boost the output of the machine.
I think that was very well received, but in some ways was kind of always expected from us.
I think the one thing that we talked about at JPMorgan that got a huge reception was the Moleculo long read technology and in particular, because of the PAG meeting, the Plant and Animal Genome meeting was the next week, and the kinds of customers we have at the PAG meeting are those exact target customers for long read lengths.
So there was tremendous excitement about the ability to begin to address some of these more complex plant genomes, very large and non-deployed genomes using the Moleculo technology.
So I think that was in the short term unexpected and of very high interest.
Ross Muken - Analyst
Great.
Thanks, guys.
Operator
Bill Quirk, Piper Jaffray.
Bill Quirk - Analyst
First question, you guys have been pretty nimble in the past around capacity expansions, and given the strong MiSeq order rate, can you help us think about plans for expanded production, how quickly we could work down the backlog?
Christian Henry - SVP & General Manager, Genomic Solutions
Yes.
Bill, it's Christian.
We will work down the backlog quickly.
We have a very strong rate of production each week, but the demand was so strong in the fourth quarter, we were really limited by some of the raw materials coming in, not so much the capacity of the plant.
And so as a result, we've accelerated some of the receipts of raw materials, and we'll get back on track this quarter.
That being said, having a bit of a backlog going into a particular quarter and possibly even exiting the first quarter from a production perspective isn't a bad thing because it allows you to balance your production between all of the products.
Today in our Hayward facility, we manufacture the HiSeq 2000, the 2500, the MiSeq, and so we're able to -- with that bit of backlog, we're able to balance the production across all of the product families.
So we're very fortunate to have higher -- more demand than we were expecting, and it was really -- at the end of the day, it was the raw materials coming in that precluded us from delivering everything we wanted to get out the door.
Bill Quirk - Analyst
Got it.
And then just a couple of quick accounting questions.
What does the guidance assume about sequestration?
And then secondly, and maybe this one's specifically for Marc, how do we think about the Verinata accounting?
Is that going to be accrual or cash based, or is it going to be cash until obviously we start rolling up some reimbursement coverage?
Thanks.
Marc Stapley - SVP and CFO
Let me take the Verinata one.
The way we're going to do that is obviously, we're going to do it on a GAAP basis.
If we think the recoverability is reasonably assured, we'd take the revenue.
Obviously early on, that's not necessarily the case, and so we'll take revenue on more of a cash basis.
Jay Flatley - President and CEO
With respect to the NIH assumptions, sort of the baseline assumption that we have is a 2% to 4% decrease as a as a result of the sequestration -- or the no sequestration is probably a better way to say that.
I think we've consistently said that if it winds up being a flat budget, that's going to be upside opportunity for us.
If it winds up sticking at the minus 8%, that's probably some downside risk, but we think the chances of winding up at minus 8% are very small.
Bill Quirk - Analyst
Got it.
Thanks, guys.
Operator
Daniel Brennan, Morgan Stanley.
Daniel Brennan - Analyst
Just a few questions.
Maybe on the 50 person headcount investment, could you provide some details about the focal point for this increased sales force, maybe end markets, geographies and kind of related to that?
Should we consider this as kind of building for a multi-year future, or is this something that once you do this, 2014, is this something we should maybe expect as your demand increases and kind of clinical markets, you might have to continue to step up the investment?
Jay Flatley - President and CEO
I would think about this largely as a 2013 step change.
The 50 is incremental to what we would have done otherwise.
I think we'll certainly invest heavily in clinical accounts or clinical sales type people in our TCG business.
There will be some investments in sales force related to cytogenetics work that BlueGnome is doing.
There will be some investments for going after new markets like forensics, and there will be a general geographic add-on to try to increase our reach.
Daniel Brennan - Analyst
Great.
Okay.
And then maybe switching over to the MiSeq, I know you -- I believe you gave guidance for pull-through, maybe of $45,000 to $50,000.
Could you just comment on -- it seems a little bit lower than I think historically maybe we've heard in the past, kind of what you're seeing on MiSeq pull-through?
I would think there should be a lot of head room on the upside, so what kind of utilization patterns are you seeing from customers?
Jay Flatley - President and CEO
That $50,000 number is the number we've always targeted and that was even at the time we first launched it.
We said -- let's plan for $50,000, and that's about where it's come out.
What we see in MiSeq is a very interesting pattern that has to do with the aging of the systems, and we'll have to see over maybe the next year how this turns out.
But clearly, as the systems become installed for greater and greater periods of time, the output on that particular system tends to go up.
But because we're early in the product launch, we do have a very large number that are at the front end of that curve that have very low consumption because customers are developing assays or really beginning to think about how to deploy the technology.
So we think as we look forward maybe a year, there's a chance that number could begin to move up as more of these get put into production environments, as clinical customers begin to use them routinely in labs.
But I think for fiscal '13, using a number in that $50,000 range is probably the right place to be until we know otherwise.
Daniel Brennan - Analyst
Great.
If I could, on ovarian and gastric, Jay and Christian, any update there on how we should be thinking about timing for those colorectal?
Jay Flatley - President and CEO
No update today on that.
Daniel Brennan - Analyst

Operator
Isaac Ro, Goldman Sachs.
Isaac Ro - Analyst
Jay, could you maybe give us a little color on how the economics for Verinata will work?
As I understand it, you guys are handling the sales and marketing while Perkin is taking care of the billing.
Just wondering if we can infer that you guys would shoulder a little bit more than half the cost in exchange for more than half the revenue and earnings?
Jay Flatley - President and CEO
We can't give you specifics of the agreement because those are confidential.
What I can say is that the actual sales efforts at least in the near term are going to be divided up.
Verinata had a direct sales force.
That direct sales force will stay in place, and PerkinElmer has their own sales force.
So PerkinElmer will do sales, marketing into their channel, and all the billing and reimbursement, but Verinata will also -- does have and will continue to have a direct sales operation as well.
Isaac Ro - Analyst
Okay.
Great.
That is actually helpful.
And then in terms of the future technologies, chemistry A&D, any color you can provide on where those next-gen chemistries stand in development?
Jay Flatley - President and CEO
No, not a lot on than.
I guess what I can say is that we've begun to work as I've said publicly in the area of Nanopores.
And so we have diverted some investment over toward Nanopores, and we've continued to make unbelievable progress on SBS.
If you look at sort of the ratio of dollars being spent on alternative chemistries, it's probably shifted a little bit away from A&B just because we're making so much progress on SBS and we're working on Nanopores in addition.
Isaac Ro - Analyst
Great.
If I could just sneak in one last one on BaseSpace, maybe comment a little on what percentage of the installed base is actively using the technology, and where do you think that's eventually going to get by the end of this year once you've got the entire platform theoretically enabled?
Is there any color on that, for pull-through and so forth?
Christian Henry - SVP & General Manager, Genomic Solutions
On MiSeqs right now, we have about 70% of the customers connected, and we think that is pretty close to the theoretical number.
It may inch up a little bit from there, but there is a fraction of the installed base that just is not allowed to be connected to the Internet, so that will never be 100% no matter how well we do.
Of that 70% that are connected, I believe the current number that's uploading data is about half of them.
Jay Flatley - President and CEO
Half.
Christian Henry - SVP & General Manager, Genomic Solutions
Half of the 70% are actively uploading their actual data runs.
Most all of the 70% are uploading the health information.
So we are being able to use this in very powerful ways now to sort of watch the quality metrics in the field on an aggregate basis and diagnose problems earlier.
It's an incredibly powerful tool for us.
On the HiSeq front, it's really too early to know because it just began really around December 1 with the shipments of the first 2500s.
And as I said previously, we expect the connection rate of HiSeqs to be slower in the installed base because everybody who owned a HiSeq previously already has some local IT infrastructure to support it, so they either have to give that up or begin to switch over time to the use of BaseSpace.
So that migration, HiSeq front, will be slower.
Isaac Ro - Analyst
Thank you.

Dan Leonard - Analyst
On the price increase front, I think Marc mentioned you're going to issue another price increase in the second quarter, so I wanted to confirm that and also get some color around your thinking around consumables pricing going forward.
Jay Flatley - President and CEO
Yes, that's right, we've notified our customers of a small price increase that will take effect on April 1. And with respect to other price increases, those are the only ones we've announced.
There's nothing more.
Dan Leonard - Analyst
Jay, is this similar to the prior price increase where customers could avoid it by pre-buying or pre-ordering a certain -- committing to a certain volume in advance of that?
Jay Flatley - President and CEO
Well, they can in a sense that they can -- if they want to front load orders in Q1, they can do that.
We're not going to prevent them from ordering under the existing pricing, and if they do that before the price increase takes effect, we'll honor that order.
But recall that that doesn't affect revenue.
It only affects orders.
Those orders will be shipped out on whatever shipment schedule they put in with the order.
There's no impact in Q1.
Dan Leonard - Analyst
Lastly really quick, you mentioned you're rolling out -- the full roll-out of your e-commerce channel is going to occur in Q2.
Can you qualitatively help us understand what kind of e-commerce contribution you have in your forecast?
Is it still pretty minimal or immaterial at this point, or do you think it will be something more than that?
Jay Flatley - President and CEO
Let me clarify my remarks a bit there.
The e-commerce comment I made was with respect only to BaseSpace.
So it has to do with the fact that we're able to put apps up, but we put them up initially for free so customers can use them as we bring up the e-commerce infrastructure, which will take effect in Q2.
The answer to the opportunity size there is a hard one.
We have very broad models internally about what the app rate usage might look like, all sorts of assumptions that frankly are all over the map, if you will.
So it's hard for us to predict right now what the usage rates are going to be, and so I think we've decided to just wait and actually see what it is rather than spend too much time trying to predict it at this point.
Dan Leonard - Analyst
Thank you.
Christian Henry - SVP & General Manager, Genomic Solutions
I think one thing that's exciting though is we have -- what is it -- over 120 or well over 100 developers that are developing software for BaseSpace, so it will be interesting to see how that monetizes itself out over time.
Jay Flatley - President and CEO
That number is the number of people who downloaded the development kit.
It's a little hard to know exactly how -- what fraction of that 125 will actually be producing apps, but it's a good sign.
Operator
Dan Arias, USB.
Dan Arias - Analyst
Just following up on sequencing costs, Jay, how important do you think it's going to be to compete on the $1000 genome price point this year?
Obviously what you get for a particular price varies between platforms, but I'd love to hear your thoughts on the way you think customers will look at cost per sample this year as some new products are rolled out.
Jay Flatley - President and CEO
I think the $1000 price point does have a magical ring to it in a lot of people's minds, particularly because it's been talked about so aggressively for so long.
I don't think the market's going to get to the $1000 price point this year if you do the math the way we do the math.
I just don't think any technology's going to get to the $1000 price.
In '14, I think it's certainly possible.
When we do the calculation, we include reagents, instrument amortization and that, bioinformatic storage and processing of the data through a pipeline that at least gets you to variant.
The only thing we don't include when we do that math is the overhead because overhead can vary from institution to institution and be widely affected by other things that that entity is doing.
If you add up all those other components besides overhead, the $1000 is not going to happen in '13, I don't think.
Dan Arias - Analyst
Got it, thank you.
Then just on Verinata, where is production capacity now relative to test uptake?
As you think about taking Verify to a broader audience, is expansion there at all a consideration in the near or midterm?
Jay Flatley - President and CEO
We built the laboratory to be very easily expandable.
If you look at any of the workstations and the work flow that they've set up, they can expand very significantly relatively quickly, and clearly on the sequencing side, that's not an issue now either because we can presumably close the deal, very easy for us to add incremental sequencers if we need to.
I don't think capacity's going to be any challenge.
Dan Arias - Analyst
Quickly, Marc, maybe just one quick one for you.
Did you sort of give a tax rate for '13 that we should think about?
If you didn't, would you be willing to comment there?
Marc Stapley - SVP and CFO
Yes, we said you should think about the pro forma tax rate for next year being around 31%.
Dan Arias - Analyst
Okay.
Thank you.
Marc Stapley - SVP and CFO
Dan, just to clarify, included in that is the 2012 R&D tax credit that we didn't recognize in 2012 in the prior year, we'll take that in Q1.
Jay Flatley - President and CEO
I probably should give some kudos to our operations team for all the hard work of moving the products over to Singapore.
It's been a couple of years of front-end investment as we move our property there and made the investments to actually bring up the manufacturing infrastructure.
Now we're starting to see that begin to pay significant dividends, so all that hard work's paying off.

Vamil Divan, Credit Suisse.
Vamil Divan - Analyst
Just a couple I had here.
One, in terms of the MiSeq Dx.
What's your sense in terms of sort of the internal time line for obtaining updated clearance there, and is there anything you can share just in terms of how the discussions are going so far?
Jay Flatley - President and CEO
To my knowledge, we've not gotten back our first response from the FDA.
I guess that could have happened in the last few days and I don't know about it, but at least to my knowledge, we've not heard from them yet.
Our default assumption is that it would be sometime in the second quarter unless there's some significant issue that pops up.
That would be a typical time line, and we just don't know which month it would happen in the second quarter.
I do think we will put out a press release when that occurs.
That would be a significant event for us, and we'll announce that when it happens.
Vamil Divan - Analyst
Thanks.
And then in terms of the clinical customers, obviously we talked a lot about oncology and reproductive health.
Are you seeing much use with the MiSeq so far in other areas besides those two, infectious diseases or other areas, or is it pretty much just limited to those two for now?
Jay Flatley - President and CEO
The usage is quite broad.
It's across -- we're seeing it in microbiology, in virology, certainly in infectious disease.
We think cancer and reproductive health are the biggest short-term and fastest growing parts of the market, but I think it will be used quite broadly and into forensics as well.
Christian Henry - SVP & General Manager, Genomic Solutions
Well, and the food testing, the FDA, big order we announced last quarter.
Vamil Divan - Analyst
Just one last quick one, if I could.
In terms of tax rate again, you mentioned the first quarter will get some of the impact on the R&D tax credit.
Is there any number you could assist with there in terms of what we should think for the first quarter?
Marc Stapley - SVP and CFO
It will be something like 50 basis points for the year.
Vamil Divan - Analyst
What will the Q1 impact, catch up from '12?
Marc Stapley - SVP and CFO
Q1 impact.
Probably bring the tax rate down about 300 basis points in the first quarter (sic).

Question for Marc.
Marc, ERP changes are never typically short-term projects, and you mentioned a $10 million investment in 2013.
Can you talk about the timing of the project going forward and how you're planning on adding additional investments beyond 2013?
Marc Stapley - SVP and CFO
Yes, couple things.
To clarify, the $10 million isn't necessarily related just to the ERP project.
It's related to a couple of programs as Jay talked about.
The term of that project -- so that was the investment for 2013, but we think of that as a two to three year program overall, ERP.
I think about -- within about three years from now, we'll be done with the final implementation of whatever solution we end up deciding to go with.
Jay Flatley - President and CEO
I think the focus of 2013 is largely going to be on defining the business processes, the core business processes, selecting the system and then beginning to plan for implementation.
It's very unlikely we would actually begin implementation in 2013.
Amit Bhalla - Analyst
Just a second -- sorry.
Go ahead.
Marc Stapley - SVP and CFO
As you get into the implementation, of course, some of your spend is capitalized, and the mix between capitalization and OpEx will change, and then that will come back in depreciation over the life of the solution you've implemented.
Amit Bhalla - Analyst
Right.
Jay Flatley - President and CEO
One of the things we're trying to do though is, to the extent as we go through the process exercise, we can find quick wins.
That's a key objective of ours, particularly as we start to work towards driving gross -- continuing to drive gross margin up.
Amit Bhalla - Analyst
And a follow-up question.
On Nanopore, qualitatively, what's the incremental level of increase in R&D spending you're putting toward Nanopores this year?
I can't imagine that you're just starting the work in this area.
So what's the incremental level of increased R&D?
Jay Flatley - President and CEO
Well, we've not disclosed what it was before or what the increment is.
I don't think we'll get to that level of granularity.
But what we can say is that our investment in Nanopore technology really was focused on our partnership with Oxford Nanopore until that partnership went a different direction.
We weren't working on it previously.
Our focus was on working with Oxford.
Amit Bhalla - Analyst
I wasn't asking for a number.
I was just thinking more in terms of are you doubling it, are you tripling it, just to get a sense of your R&D focus.
Jay Flatley - President and CEO
We're not going to subdivide it any further.
Amit Bhalla - Analyst
Okay.
Operator
Jon Groberg, Macquarie.
Jon Groberg - Analyst
Just if I can, a couple clarifying ones, and I actually have a technology question.
So one is on the share count.
Are you assuming a certain amount of buybacks?
Basically it looks like you're assuming no dilution for the year.
Obviously you've been issuing quite a bit of stock comp.
Marc Stapley - SVP and CFO
Jon, just assuming, it's a couple of things.
Remember, we have about just over $165 million, I think it is left, in the program.
We still have the discretionary plan dialed in, and that will continue to operate throughout this year.
I'm sorry.
We still have the discretionary element as well.
We could utilize that when we need to.
That would all be assumed.
Anything we plan to do would be assumed in our guidance.
Jon Groberg - Analyst
One more quick one on the guidance.
Are you -- maybe you can just talk about what your utilization expectations are and are you anticipating instruments will be up in 2013?
And I guess Jay, normally you've given a wider range of guidance, now you're just kind of saying 15%.
What do you think the kind of the variance around that guidance is?
Is it 15% plus or minus 1%?
2%?
Maybe help us out there.
Jay Flatley - President and CEO
We're not going to get any more specific, Jon, than the number we picked.
We thought long and hard about how to present it best, and this is how we decided to do it.
You can assume some bands around the 15%, and I think that where we're going to stick in terms of any specifics is at the 15% level.
So we think that's a great number for us going forward, and we're optimistic that we can wind up in that range.
Jon Groberg - Analyst
Okay.
And just on the instruments, you expect those to be up, and what's your utilization expectations, kind of within that range you've given, is it just the mid-point of those ranges that you gave for your annual, those annual ranges that you've said, is your expectation the mid point of that for 2013?
Jay Flatley - President and CEO
Remember how -- the logical way we would calculate guidance is to look at all the variables in our business, to map them all out on one end of the scale, map them all out the other way and upside downside, see how broad that range is and decide sort of what the probabilistic thing is in the middle.
The numbers we gave doesn't assume a single point assumption on every factor in there.
It assumes a wide range of how any one factor could vary, whether it's instrument placements or utilization, and we look at that entire model and decide what the right guidance number is.
It doesn't assume a point number for utilization, instrument, consumables.
Jon Groberg - Analyst
Okay, that's fair.
And my quick technology question for you, Jay, is -- I'm pretty fascinated on this, I think it was in your -- a few weeks ago in your release, you mentioned today again of the MiSeq that you're now doing exomes.
My conversation with a lot of users previously was that you didn't have enough reads on the MiSeq.
I think your reads are still around 15 million and you're increasing the read length.
Now I think you said that with 4G to 6G, you're able to do an exome.
Just curious what you've gotten around or what allows you to do Exomes on a MiSeq.
Jay Flatley - President and CEO
Well, the amount of total output really is what determines what you can do in Exomes, and it's not as much limited by the number of tags.
It's not accounting applications, sequencing output application, and we're pushing MiSeqs in the field, are really running at 8G plus and we're moving that up to 15G.
That's going to have enough output to do Exome.
Jon Groberg - Analyst
Aren't most exomes120 base pairs long?
Jay Flatley - President and CEO
Depends on what your kit creates when you're done, right?
So we read both directions.
So it's not a counting application.
Jon Groberg - Analyst
All right.
I was just curious.
Little different from what people have said.
I think that's a big mover if you could get some good data there.

Unidentified Participant
This is Eric [Krizello] filling in for Peter.
On your academic customers, have you seen any change in their tone or their outlook, either positively or negatively, within the past several months?
Jay Flatley - President and CEO
No.
We said in the script that our customers had very stable behavior, very stable ordering rates, and we were surprised actually at how unaffected they seemed to be by any of the macro conditions or the sequestration risk that still hangs out there.
Obviously we've been very pleased by that response.
Unidentified Participant
Great.
Thanks for that color there.
And then on the gross margins, can we maybe see that just improve sequentially as 2013 goes on, or is there going to be kind of a year end improvement more than the first half of the year?
Jay Flatley - President and CEO
Well, I mean, our goal of course is to continue to make quarter-to-quarter progress on gross margins.
That doesn't always happen because there are one-time things that happen in any given quarter, some of which wash out on the upside and the down side.
But the goal would be to continue to march gross margins up on a regular basis if we can.
Unidentified Participant
Okay.
And then just lastly, the service gross margins, is there a target that you're looking for, like a steady state or full year margin number?
Because it's kind of bouncing around a little and it is dilutive to your overall margin.
Jay Flatley - President and CEO
It is.
As the service goes up, as a fraction of revenue, that's as Marc mentioned, a bit of a downdraft on the corporate gross margins.
We don't have a limit on what we think we can do there.
We'll continue to work to drive them up, and there's no short-term target.
We're working to make them better.
