The 30-second take

Charles River's growth slowed down this quarter as their biotech and pharmaceutical clients became more cautious with their spending. Management sees some early positive signs that demand is starting to stabilize, but they remain careful about the near-term outlook. They narrowed their full-year financial forecast, reflecting a mix of some improvement and ongoing challenges.

Key numbers mentioned

  • Third quarter organic revenue growth of 4.1%
  • Third quarter earnings per share of $2.72
  • DSA segment revenue of $664 million
  • Expected NHP utilization in safety assessment studies for 2023 of approximately 11,400
  • Annualized cost savings from restructuring actions of approximately $40 million
  • Free cash flow guidance for the year narrowed to a range of $340 million to $360 million

What management is worried about

  • Biopharmaceutical clients remain cautious with their spending, reprioritizing pipelines and conserving cash.
  • The Manufacturing segment is experiencing softness across broader end markets, attributed to a post-COVID slowdown from manufacturers and CDMOs.
  • The RMS segment experienced slower demand from mid-tier clients, including biotechs and CROs.
  • Clients, particularly CDMOs, are cutting costs as part of COVID destocking efforts and reducing testing volumes.

What management is excited about

  • They are seeing early encouraging signs that support a belief the demand environment will stabilize.
  • The Safety Assessment business saw sequential improvement in both the study cancellation rate and the net book-to-bill ratio in the third quarter.
  • The cell and gene therapy CDMO business had another solid quarter with a strong double-digit growth rate.
  • They are having active discussions with clients about adopting virtual control groups for toxicology studies to reduce animal usage.
  • They have made several investments in non-animal technologies, like AI for discovery and 3D tumor modeling.

Analyst questions that hit hardest

  1. Derik De Bruin (Bank of America) - NHP pricing benefit and EPS impact: Management responded that it's "a little bit of an impossible" to say when or if prices will come down, emphasized that benefits were more modest than some predict, and stated they prefer to stay away from pricing specifics.
  2. Casey Woodring (JPMorgan) - Revenue per NHP trends: Management gave a detailed answer about study mix driving the metric, but concluded it's "hard for us to predict" forward-looking trends as it depends on uncertain client priorities.
  3. Max Smock (William Blair) - Margins on NHP work and mid-term guide assumptions: Management confirmed NHP work has slightly higher margins but did not provide specifics on what is baked into their mid-term guidance regarding pricing normalization.

The quote that matters

We believe the current client spending patterns will persist in the near-term.

Jim FosterChairman, President and CEO

Good morning. We reported third quarter organic revenue growth of 4.1% and earnings per share of $2.72, both of which exceeded our prior outlook. As anticipated, our growth rates declined from first half levels, reflecting the difficult comps from last year and the moderating demand that is affecting our businesses this year. Looking at the biopharmaceutical end market environment, we believe certain demand trends showed some early positive signs, but clients also remain cautious with their spending. Biopharmaceutical clients are continuing to reprioritize their pipelines and in some cases, conserve cash or streamline their cost structures. This has led to a meaningful impact on some of our businesses this year, including Discovery Services and our Manufacturing segment and began to have a more discernible impact on the RMS business in the third quarter. We believe the current client spending patterns will persist in the near-term. However, we are also seeing some early encouraging signs starting to emerge, which support our belief that the demand environment will stabilize. In the Safety Assessment business, we were pleased to see sequential improvement in both the study cancellation rate and the net book-to-bill ratio in the third quarter. These favorable trends are supported by external indicators, including a stable biotech funding environment. The third quarter was the second consecutive quarterly increase in biotech funding on a trailing 12-month basis, led by venture capital investments. I will now provide highlights of our third quarter performance. We reported revenue of $1.03 billion in the third quarter of 2023, a 3.8% increase over last year. Organic revenue growth of 4.1% was driven by all three business segments, led by a mid-single-digit increase in the DSA segment. As I mentioned earlier, the third quarter growth rate was affected by a difficult comparison to last year that included organic growth of 15.3% in the third quarter of 2022. By client segment, third quarter revenue growth was driven by solid demand from global biopharma clients and academic institutions. As has been the case throughout the year, the growth rate for small and midsized biotech slowed as these clients are being more selective with their spending. Growth of biotech clients last year also outpaced all other client segments, driving the particularly difficult comparison in the second half of the year. The operating margin was 20.5%, an increase of 10 basis points year-over-year. The slight improvement was driven primarily by the DSA segment as well as lower unallocated corporate costs. These improvements were largely offset by margin pressure in both the RMS and Manufacturing segments. Earnings per share were $2.72 in the third quarter, an increase of 3.4% from the third quarter of last year. This exceeded our prior outlook, due primarily to the top line outperformance. In addition, the year-over-year headwind from interest expense is beginning to dissipate. We have tightened our revenue and non-GAAP earnings per share guidance ranges for 2023 as we move into the final quarter of the year. We are narrowing our organic revenue growth guidance to a range of 5.5% to 6.5%, and our non-GAAP earnings per share guidance to a range of $10.50 to $10.70, which raises the bottom end and trims the top end of our prior range by $0.20 per share, respectively. The guidance update is primarily due to shifts in the gating of our forecast between quarters and the favorable impact of lower third quarter cancellations in the Safety Assessment business being largely offset by a reduced outlook for our Manufacturing Solutions segment in the fourth quarter. I'd like to provide you with additional details on our third quarter segment performance, beginning with the DSA segment's results. DSA revenue in the third quarter was $664 million, an increase of 5.3% on an organic basis. Safety Assessment business continued to drive DSA revenue growth with contributions from base pricing and higher study volume, driven by non-NHP related work and post-IND studies. NHP pricing was a modest benefit to the growth rate. However, the overall demand environment continues to impact discovery spending as clients focus on post-IND work. We believe stabilizing demand trends and significant backlog coverage will enable us to achieve our financial targets, including high single-digit DSA organic revenue growth for 2023, which is above our prior outlook for the segment. The DSA operating margin was 27.2% in the third quarter, a 100-basis-point increase from the third quarter of 2022. Before moving on to RMS, I'd like to comment on our NHP-related study work. At our Investor Day in September, we provided some information around the benefit from NHP pricing on our DSA revenue growth rates. We believe that additional information would be useful for investors and analysts to gain a better understanding of the impact of NHP pricing and NHP-related safety assessment studies on our business. Over a three-year period ending in 2023, NHP pricing is expected to benefit DSA revenue growth by a total of just $230 million or approximately 30% of our total DSA revenue growth since 2020. Without the impact of NHP pricing, DSA revenue would still have increased at a high single-digit growth CAGR since 2020. In total, NHP Safety Assessment study revenue, which includes both services and the embedded NHP revenue, is expected to represent approximately 30% of DSA segment revenue in both 2022 and 2023. NHP pricing has rapidly escalated since 2020 due to both NHP supply constraints and the continued increase of biologic drugs in development. Supply constraints began in China around the pandemic and intensified last year due to the Cambodian NHP supply situation in the US. This has caused NHP pricing to increase by approximately $20,000 per model in aggregate since 2020. In 2023, we expect to utilize approximately 11,400 NHPs in safety assessment studies worldwide. This represents a reduction of approximately 25% from over 15,000 in the prior year, driven principally by the current level of biopharmaceutical demand and our clients' focus on their post-IND safety assessment work, which generates higher service revenue per model due to the longer-term nature of these studies, resulting in fewer NHPs being used to generate that service revenue. A long-standing strategic imperative of the company is responsible animal use, which includes modifying or reducing animal usage. Responsible animal use is firmly embedded in our commitment to animal welfare and the 4R principles. Its adoption accelerated this year as a result of the NHP supply constraints. One example of our progress is the introduction of virtual control groups for toxicology studies. Virtual control groups, or VCGs, replaced the animals in control groups with existing randomized datasets and statistical evaluations. It will take some time to adopt, but we are having active discussions with our clients about VCGs. As many of you are aware, we have committed to providing additional disclosure on NHP sourcing, and a comprehensive update on our NHP strategic initiatives in early 2024. We will do this by leading with science, remaining committed to our essential mission of creating healthier lives and ensuring patient safety and by consistently challenging ourselves to raise the bar. And as we look to the future, we will be focused on ensuring a sustainable supply chain, particularly for NHPs, and we'll also pursue a longer-term strategy to lead the industry in adopting animal alternatives. Our team is diligently working to continue to enhance our processes and key initiatives in these areas. We've already made several investments in non-animal technologies, ranging from our Endosafe Trillium launch this summer for endotoxin detection testing, to our technology partnerships with Valo for Discovery AI, PathoQuest for next-gen sequencing for in vitro viral study safety testing, and Cypre for 3D tumor modeling. We look forward to sharing our NHP strategic update in early 2024. RMS revenue was $186.8 million, an increase of 3.2% on an organic basis over the third quarter of 2022. This is below the year-to-date high single-digit revenue growth rate for two primary reasons: slower demand from mid-tier clients, including biotechs and CROs; and the timing of NHP shipments within China as we anticipated last quarter. The timing of NHP shipments within China is transitory. We expect NHP revenue in China will improve in the fourth quarter, although some shipments will slip out of 2023. For the year, we expect RMS organic revenue growth will be in the mid to high single-digit range. In the third quarter, we generated revenue growth in our small research models business and in the services business. Our client segment demand from global biopharma clients and academic institutions remains robust and drove RMS revenue growth. But as I mentioned, this was offset by mid-tier clients affected by the broader biopharma demand environment as well as by softer demand from government accounts. Small molecules revenue increased across all geographic regions, including China, principally driven by price. Our services business continued to report healthy growth, led by in-sourcing solutions and our CRADL operations. Our CRADL sites, or our flexible vivarium rental space, remain well utilized overall and continue to generate significant year-over-year revenue growth. In the third quarter, the RMS operating margin decreased by 460 basis points to 18.9%. The significant decline was driven by the mix of business, which favored academic clients in our Insourcing Solutions business, as well as the timing of NHP shipments within China. We expect the RMS operating margin will rebound in the fourth quarter due in part to the timing of the China NHP shipments. In addition, as we mentioned at Investor Day, we are reviewing the profitability of certain Insourcing Solutions contracts, which should benefit the RMS operating margin in the future. Revenue for the Manufacturing Solutions segment was $175.7 million, an increase of 0.9% on an organic basis compared to the third quarter of last year. The segment is experiencing softness across the broader end markets, which we attribute to a post-COVID slowdown from biopharma manufacturers, CDMOs, and their suppliers. These market conditions started to more noticeably impact the Microbial Solutions business in the third quarter. Clients, particularly CDMOs, are cutting costs as part of their COVID destocking efforts and reducing testing volumes, and fewer programs advanced into the clinic, but these clients must continue to manufacture commercial products. So we believe the long-term growth trends for our Manufacturing segment will reemerge after a period of right-sizing. For Microbial Solutions, the global biopharma demand environment is affecting our Endosafe endotoxin testing product line as clients reduce both testing volumes and investments in new instruments. This includes China, where we have a small microbial operation and like many life science instrumentation companies have seen a decline in client demand. However, other areas of the business, such as Accugenix microbial identification services, continued to perform well. Third quarter trends in biologics testing were similar to those experienced since the beginning of the year. The sector continued to be challenged by the tighter funding environment, which is resulting in clients reprioritizing projects and reducing demand for services that can be conducted at various times during the development process, including viral clearance and cell banking. While not immune to the end market challenges, in the other manufacturing businesses, the cell and gene therapy CDMO business had another solid quarter. Its strong double-digit growth rate in the third quarter reflected the success of the initiatives the CDMO team has implemented since the beginning of 2022 to improve performance. We are working diligently to continue to expand our CDMO sales pipeline of new products and are pleased to have cleared several regulatory audits in recent months, including European EMA approval of our Memphis site for the production of a second cell therapy product. We believe that successful regulatory audits will generate additional client interest and support our expectation that we will add new commercial clients. The Manufacturing segment's operating margin declined by 410 basis points year-over-year to 24.5% in the third quarter of 2023, but did improve again sequentially. The year-over-year margin decline reflected the lower revenue growth rate and the softer demand trends across the manufacturing end markets. We are intently focused on driving operating margin improvement in the Manufacturing segment, including the profitability of the CDMO business as this segment is expected to be the largest contributor to achieving our 2026 margin targets. We believe our leading position as an outsourcing partner for our clients' drug discovery and nonclinical drug development efforts is helping us to manage in the current demand environment. The IND enabling and associated nonclinical services that we provide are mandatory to help clients advance their programs into the clinic and eventually to commercialize drugs. Our portfolio also differentiates us in the marketplace, because of our unique focus on early-stage R&D solutions, and our ability to distinguish ourselves scientifically. We believe that these attributes combined with our continued ability to leverage the significant DSA backlog will enable us to achieve our financial targets. Our value proposition of delivering exquisite science and driving greater efficiency and speed to market continues to differentiate Charles River in the marketplace and is reinforced with today's more budget-focused client base. To conclude, I'd like to thank our employees for their exceptional work and commitment and our clients and shareholders for their continued support. Now Flavia will provide additional details on our third quarter financial performance and updated 2023 guidance.

Flavia PeaseExecutive Vice President and CFO

Thank you, Jim, and good morning. Before I begin, may I remind you that I'll be speaking primarily to non-GAAP results, which exclude amortization and other acquisition-related adjustments, costs related primarily to restructuring actions, gains or losses from certain venture capital and other strategic investments, and certain other items. Many of my comments will also refer to organic revenue growth, which excludes the impact of acquisitions, divestitures, and foreign currency translation. We're pleased with our third quarter results, which included 4.1% organic revenue growth and an operating margin of 20.5%, representing a 10-basis-point increase on both a year-over-year and sequential basis. Non-GAAP earnings per share of $2.72 for the quarter represented a 3.4% increase over the prior year. As expected, increased interest expense, a higher tax rate, and the divestiture of the Avian Vaccine business continue to restrict year-over-year earnings growth rate, but the headwind is beginning to dissipate as we anniversary last year's interest rate increases. Our third quarter results outperformed our prior outlook, but as Jim discussed, we remain cautious with regard to the biopharmaceutical end market demand environment. Our updated outlook for the year reflects our normal practice of narrowing our guidance ranges as we move into the fourth quarter, as well as a shift in the gating of our forecast between the third and fourth quarters. This is due in part to lower cancellations and study slippage than forecasted in the third quarter in the DSA segment, offset by a reduced outlook for the Manufacturing segment in the fourth quarter. Given the cumulative effect of these factors, we have narrowed our revenue growth and non-GAAP earnings per share guidance for the full year. We now expect revenue growth in a range of 2.5% to 3.5% on a reported basis and 5.5% to 6.5% on an organic basis, which represent the low end to midpoint of our prior ranges. We expect continued pressure in the Manufacturing segment, reflecting the softer demand trends, including in the Microbial Solutions business, which we believe will be partially offset by a more favorable outlook for our DSA segment for the year. We expect that the consolidated operating margin will be modestly lower than in 2022, resulting in non-GAAP earnings per share guidance in a range of $10.50 to $10.70 compared to our prior outlook of $10.30 to $10.90. We'll continue to manage the business in a disciplined manner with a focus on setting achievable financial targets, protecting our operating margins by managing costs, driving greater efficiency, remaining disciplined with our investments, taking share, and implementing other initiatives to improve performance and manage effectively in this environment. We continue to evaluate our operations and we'll appropriately manage our cost structure to align with the current domain environment. Restructuring actions implemented this year are expected to generate approximately $40 million in annualized cost savings. Our updated revenue growth outlook reflects slight revisions for each of our segments. As I just referenced, we are reducing the outlook for our Manufacturing segment to be flat to low single-digit organic growth from our prior outlook in the high single digits. For the RMS segment, we have widened the bottom end of our outlook to mid to high single-digit organic growth. This reflects the timing of NHP shipments in China, some of which may be deferred to 2024. Our RMS segment also experienced a more discernible impact from mid-tier biopharma clients' softer demand. Our improved outlook for the DSA segment to high single-digit organic revenue growth principally reflects the lower cancellations and study slippage in the third quarter that I referenced. I will now provide some additional details on the non-operating items that affected our third quarter performance. Unallocated corporate costs in the third quarter totaled $48 million, or 4.7% of total revenue, compared to 5.8% of revenue last year. The decrease was primarily due to benefits achieved through our virtual power purchase agreements, or VPPAs. Despite the favorability in the third quarter, we continue to expect unallocated corporate costs to be approximately 5% of total revenue for the full year. As we announced in October, we have achieved 90% renewable electricity globally through a solar VPPA in North America and a wind VPPA in Europe. These agreements have enabled our facilities in those regions to achieve 100% renewable electricity, providing a key component of our efforts to reduce Scope 1 and 2 greenhouse gas emissions. The third quarter non-GAAP tax rate was 21.6%, representing a 140-basis-point increase from the same period last year. The higher tax rate year-over-year was due primarily to the geographic mix of earnings. However, the tax rate was favorable to our expectations, principally because of discrete tax benefits related to U.S. R&D tax credits. For the full year, we now expect the tax rate will be at the low end of our prior range, or approximately 22.5%, due primarily to the discrete tax benefit. Total adjusted net interest expense for the third quarter was $32.4 million, representing a decrease of $1.2 million sequentially, due primarily to debt repayment. For the full year, we have narrowed our total adjusted net interest expense outlook by $1 million to a range of $131 million to $133 million, as any further rate increases by the Federal Reserve before the end of the year will not have a meaningful impact on our 2023 results. At the end of the third quarter, approximately 80% of our $2.5 billion in outstanding debt was at a fixed interest rate. Our gross and net leverage ratios were both approximately 1.9 times at the end of the third quarter. Free cash flow was $139.5 million in the third quarter compared to $60.4 million last year. The year-over-year increase was primarily due to favorable changes in working capital as well as lower capital expenditures. For the year, we have narrowed our free cash flow guidance to a range of $340 million to $360 million. Capital expenditures were $65.9 million in the third quarter compared to $72.4 million last year. For the year, we now expect CapEx to be in the range of $330 million to $340 million or below our prior outlook of $340 million to $360 million. We continue to take a disciplined approach to managing our capital deployment and are committed to aligning our capacity and capital investments with the current demand trends. A summary of our updated financial guidance for the full year can be found on Slide 37. With one quarter remaining in the year, our fourth quarter outlook is effectively embedded in our guidance for the full year. For the fourth quarter, we expect revenue to decline by nearly 10% on a reported basis and at a mid-single-digit rate on an organic basis. This will result in flattish year-over-year organic revenue growth in the second half of the year, which is consistent with the outlook provided in August. Non-GAAP earnings per share are expected to be in the range of $2.30 to $2.50. The fourth quarter outlook largely reflects a very challenging comparison to the prior year when we reported organic revenue growth of 18.8%, including DSA growth of 26.5%. In conclusion, we're pleased with our solid third quarter performance, which is evidence of the resilience of our business, despite a cautious biopharma spending environment as growth rates normalize to pre-pandemic levels. We'll continue to manage our business prudently in response to the challenges we are seeing in the broader market environment and work diligently to achieve our financial targets.

That concludes our comments. We will now take your questions.

Operator

We'll take our first question from Eric Coldwell with Baird. Your line is now open.

O
EC
Eric ColdwellAnalyst

Thank you very much. Good morning and truly appreciate all the additional details on the NHPs. I'm curious, in 3Q, could you provide commentary on the gross awards in DSA? Were those positive, above one, below one? Just any color on gross bookings in the quarter? And then on the backlog, $2.6 billion. I'm wondering if you have additional thoughts on where and when that backlog may stabilize at what level? How long it might take for the net reductions to come to an end? Thank you.

FP
Flavia PeaseExecutive Vice President and CFO

Good morning, Eric, yes, the gross bookings were above one in the third quarter. And we also, as you saw in our prepared remarks, had a sequential improvement in net book-to-bill in the quarter. So the backlog came down a little bit from the second quarter. It's at $2.6 billion now; it was $2.8 billion in the second quarter. So I think it demonstrates that things are stabilizing, and we're reverting back to the pre-COVID norm as we have been talking about.

EC
Eric ColdwellAnalyst

Jim, if I could just jump in with one more. You had an Investor Day not so long ago. Some new updates here on the timing of 3Q, 4Q impacts, maybe some additional market change over the last month or two. I'm just curious, does anything you're seeing today change your outlook on the LRP that was provided just a while ago, achievability, confidence levels? And then specifically on 2024, I know you plan to give guidance later, but the Street's hovering around $11 of earnings. I think this update might provide some controversy about whether that's a realistic target. I'm just comfort with high-level views on your comfort levels with where Street expectations are for next year? Thank you.

JF
Jim FosterChairman, President and CEO

So Eric, we feel confident about our three-year guidance that we just gave. I think those numbers are achievable both on a segment basis and on a total company basis. And I would say that, relative view on 2024, which we talked about a little bit on that call, hasn't significantly changed. But it's a complex market environment. We definitely want to see how the fourth quarter ends. We've only had a month. So it's really too early to provide any more details on 2024, but we feel good about the three-year numbers.

Operator

Thank you. We will take our next question from Elizabeth Anderson with Evercore. Your line is now open.

O
EA
Elizabeth AndersonAnalyst

Hi, guys. Thanks so much for the question. Just in terms of DSA bookings, just a follow-up from Eric's question. Do you see any impact from push-outs or timing issues? I just want to make sure that we're just looking at everything on an apples-to-apples basis? And secondarily, can you talk about the cash flow in the quarter? It's a little weaker than we had been expecting. So I just wanted to make sure I understood all of the puts and takes there. Thank you very much.

JF
Jim FosterChairman, President and CEO

So we—slippage and cancellations isn't always obvious. We've talked about that a lot. Definitely higher this year, but we're seeing a slowdown in cancellations. We definitely saw that third quarter. So pleased to see that. So it feels like things are normalizing. We're kind of getting back to pre-COVID cadence. We certainly want to finish the quarter and put it a period after that, I mean. So it's always part of the business, got more pronounced because that we had studied volumes we're booking out 18, 24 months. In some ways, that was really nice. In some ways, that was probably too long because we saw clients just booking slots that would not necessarily acknowledge that they had a study and often when they got to the point of actually committing, didn't have a study. So that's been a little bit disruptive. So we've got pretty good backlogs now. Not as long as they were, but not as sure as they were years ago. Impossible to tell where that's going to settle out. But it's moving towards a better place with more predictability, more consistency, and probably a more normal cancellation rate. I think Flavia will answer the other part of that question.

FP
Flavia PeaseExecutive Vice President and CFO

Good morning, Elizabeth. On free cash flow, the quarter actually was pretty solid. We reported about 100—close to $140 million in free cash flow, which was up almost $80 million or 130% versus the prior year, although last year was a relatively slow base. For the year, cash flow is a little pressured. Some movement on working capital, receivables, and inventory and timing of that, but I think it's still a very solid performance. We actually have lowered our CapEx for the year a little bit. Our guidance, as you saw to reflect modulation of our investment in capacity, given the current demand environment in Q3, CapEx was a little bit above 6% of sales which is below what we've been—we told you all at Investor Day that our target would be 7% to 8%. I think we are navigating the current demand environment well, fortifying our performance, and we'll deliver solid free cash flow for the year.

EA
Elizabeth AndersonAnalyst

So you're not seeing an incremental slowdown in like pharma payments or biotech payments, given the current environment? And then is that CapEx the way to think about things going forward? Just to double quick on the two things you said there.

FP
Flavia PeaseExecutive Vice President and CFO

Yes. So I'll parse those two comments out. So we are not seeing any impact or any significant impact with regards to bad debt or any similar metrics of creditworthiness. There's nothing unusual and significant in the receivables side. And then from a capital perspective, we're not coming off of the 7% to 8% that we provided about 1.5 months ago. I'm just saying that relative to that, we were lower in the third quarter.

Operator

Thank you. We will take our next question from Derik De Bruin with Bank of America. Your line is open.

O
DB
Derik De BruinAnalyst

Hi, good morning and thank you for taking my question. Hey, Jim, I appreciate the additional top line commentary on the NHPs. But I think the key question investors have is what's been the benefit from margins and EPS since 2019? And what happens when pricing goes back? I mean, rough back of the envelope, and you can always check my math. It looks like it's about a $3 benefit this year to earnings, assuming the margins are similar, but I see they're accretive. You really think that would really help clear the air if you just sort of like talked about what—how you sort of think about pricing trends? I know it's not going to go back immediately to—prices aren't going to fall back, but I do think this is like the one question that keeps coming up with investors is like, what does EPS look like as NHP pricing normalizes?

FP
Flavia PeaseExecutive Vice President and CFO

Derik, it's Flavia. I'll start, and then Jim can comment. I think it's a little bit of an impossible when and if prices will come down. We have—as I think we provided in our additional disclosures, pricing has been a benefit, but perhaps not as much of a benefit as people have predicted. We have diversified our supply base, which helps mitigate and manage through price fluctuations and volatility. As we said in our Investor Day, we have taken into consideration a modulation of pricing of NHP in our outlook. So we already took that into consideration as we provided you all our LRP numbers for the next three years. Jim?

JF
Jim FosterChairman, President and CEO

I mean I think because the prices have risen dramatically, some of that is reflected. Most of that is passed through. We think that the prices will flat, moderate perhaps, be reduced because there are sufficient numbers. We still think we'll get price besides the incremental price for NHPs as we have for the last few years and volume and mix as a result of the types of studies, what the duration is. So there's been a benefit, but I think it's more modest than people are thinking—are anticipating. I think that's really all that we could say to—we really like to stay away from pricing.

Casey WoodringAnalyst

Great. Thank you for taking our question. So just a quick follow-up. I wanted to touch on the bookings. So did gross bookings grow sequentially? Or did cancellations just drop quarter-over-quarter? And then I just have one quickly on the revenue per NHP. It looks like if we use the numbers that you gave here, 30% of DSA revenue per year is exposed to NHPs. If you back out the implied, it looks like revenue per NHP grew close to 42% year-on-year in 2023. Just how should we contemplate revenue per NHP on a forward-looking basis? Thank you.

FP
Flavia PeaseExecutive Vice President and CFO

So I'll maybe take the question on cancellations and growth in that book-to-bill. So I think we also stated in our remarks, the cancellation level in the third quarter was the lowest that we had seen since the second quarter of 2022. So I think we have been talking about a normalization of the domain environment; people going through their pipeline, reprioritization, and we had speculated that that would eventually modulate. As Jim said, slippage and cancellation is a normal part of the business, but we had certainly seen a higher level of cancellations as the backlog expanded significantly at its peak to 17 months. And so there was a lot of, I would say, rationalization and people prioritizing their compounds. The gross book-to-bill in the quarter was above 1, as we said. And so the lower cancellations did help improve the net book-to-bill sequentially in the third quarter versus the second quarter. So I hope that answers your question. And can you repeat the part about the NHP pricing?

CW
Casey WoodringAnalyst

Yes. It was just the less NHPs used this year has led to a lot higher amount of revenue per NHP. So just thinking about that on a forward-looking basis, just trends there? Any color around that trend? Thank you.

FP
Flavia PeaseExecutive Vice President and CFO

Yes. Thanks for clarifying that. Yes. And the last NHP usage and still, on a relative basis, higher revenue is driven by the types of studies that we're conducting more so. As clients seem to be prioritized and post-IND work, we are seeing the impact of that into our study mix as well. And we do a significant amount of post-IND work. These studies are longer in nature. And so from a mix perspective, they result in less units, but relatively higher revenue since you—they last longer, as I said. So it really will depend on what happens with the demand. If clients are going back to pre-IND work, you see a reverse of higher numbers of units being used. So it's hard for us to predict, at this point, given that we don't know our clients are going to be clients are going to be prioritizing their pipeline if they're focusing on pre or post-IND studies.

Thank you. We will take our next question from Patrick Donnelly with Citi. Your line is open.

Patrick DonnellyAnalyst

Hi, guys. Thanks for taking the questions. Flavia, maybe one for you, just on the margin side. Gross margins came in a little light. I mean, was that just due to the lower manufacturing side? And then you guys, obviously, offset that with the SG&A being quite a bit lower. Can you just talk about, I guess, the moving pieces on those two and the right way to think about them going forward?

FP
Flavia PeaseExecutive Vice President and CFO

Sure. So yeah, the gross margin was impacted, as you saw and appropriately pointed out, by manufacturing. And also, as we commented, RMS was a little bit impacted by the domain environment with the growth slowing down to about 3% versus last quarter, putting aside the timing of shipment of NHPs. So those two businesses were pressured in margin, and our ability to leverage fixed overhead. We did have the benefit in G&A, and I talked in my prepared remarks about the impact of our VPPA. So you put it all together, DSA had another strong margin quarter for us with operating margin expanding 100 basis points year-over-year. So in total, we were about 10 bps better at 20.5 versus Q2 as well as the prior year. And there's a little bit of a mix of businesses there. As I also indicated in my prepared remarks, we are—as I would expect, remaining disciplined in ensuring that we adjust our footprint and our infrastructure to the current demand environment. We have implemented some restructurings that will—when all completed, will translate into annualized savings of about $40 million. And so you think about the margin as we are rightsizing our businesses to the current demand environment, there's a little bit of a lag in terms of when you're going to see the benefit of these actions. But I think we commented that we expect OI to be flat to slightly down versus last year. And we provided some insights to you all in our Investor Day in terms of what we expect for the next three years in terms of margin expansion.

PD
Patrick DonnellyAnalyst

Okay. No, that's helpful. And then maybe just one more quick one on the gross bookings side. Can you just help us think about what the gross book-to-bill was last quarter? Again, just trying to feel out the numbers here without the cancellations on the gross bookings side? I appreciate it.

FP
Flavia PeaseExecutive Vice President and CFO

Yeah. So we haven't disclosed a specific number. What we have said is growth. Book-to-bill has been above one in Q3 as well as Q2. So it continues to be above. And as I said to an earlier question, what influence the net book-to-bill to be sequentially up in the third quarter versus the second quarter was the fact that cancellations were lower in the third quarter.

Dave WindleyAnalyst

Hi, good morning. Thanks for taking my question, and thanks for the additional disclosures. I appreciate that very much. I wanted to try to follow up on a couple of prior questions. So, on the kind of Casey's question, I guess, on the revenue per NHP implied. Flavia, I understand your point about—I think you're talking about like maybe long-term CAR studies or something of that sort that are—that run longer without needing more animals. Is that the exclusive impact? Or is there also like a reuse that's not in the—I'm thinking if you have 11,000 unique animals, for example, and then there are also some reuses of those animals, that would also have the effect of lowering that revenue per annum. I just want to make sure I understand the various contributors to these numbers that you've disclosed this morning.

FP
Flavia PeaseExecutive Vice President and CFO

Sure, David. Yes, the primary impact is your first point. Yes, it's CAR studies, repro studies; those tend to last longer. So we can still get the same revenue with less units. So that's the primary driver. And those types of studies, all post-IND, they were up significantly in Q3. And they have been up sort of Q3 year-to-date versus last year as well. So that, again, goes back to my earlier point of clients prioritizing post-IND work.

JF
Jim FosterChairman, President and CEO

So we have a reduction in numbers of NHPs used, with a meaningful amount of revenue associated with those just because the studies are much higher value—or much longer and are really essential to be getting drugs through the clinic. So a little bit of a shift at least for this year. It's difficult to say help, but we usually have a pretty good balance between IND files and post-IND work, but that's a really good explanation for why the units are down.

DW
Dave WindleyAnalyst

Got it. Okay. Jim, on the—there are a couple of comments, I think, in the deck this morning about kind of technology references. I know in the past, the general view has been that as much as we'd like to be able to spare animals or shift to virtual technologies and silicon technologies, that those are probably a long way off. One of your lines in the deck this morning kind of references that like maybe there's a little bit more promise there. And I wanted to—and kind of that we're going to lead the industry context. I wondered, if you'd comment on that is, am I over reading that?

JF
Jim FosterChairman, President and CEO

Well, I'm glad you asked that, Dave. So, Charles River has a responsibility to utilize alternative adjunct technologies to the extent that they actually exist and work, and regulators and clients will embrace that. And they'll give us decent information. And so, as the largest provider of research models, as the largest company, we have to lead. So we have multiple investments, relatively small, except for one multiple investments and a whole bunch of different technologies, particularly AI, next-generation sequencing, and 3D modeling would be once it come to mind immediately. I met with a company yesterday that's in the AI field, so that's probably going to be another one. And it's impossible to tell how much traction we'll get, but I do think that there's a fair amount of work being done right now. And I can see it sooner than later in discovery, and we can see it sooner than later in helping the clients identify a lead compound and moving away from other drugs that we're working on that probably don't show efficacy and being able to do that with non-animal technologies or fewer animals. And hopefully, that would speed up the whole process of them moving towards the clinic. So we feel really good about that. Dave, I couldn't guess how far away this is, but I think we'll see some of the discovery impact. And I think—we think that's beneficial for the industry and for us sometime maybe in the next five years. I don't think it will be substantial. But I do think it will be real. To the extent to which those technologies work, those are likely to be companies that we buy or technologies that we license. And never is a long time, so I won't use the word never, but from everybody that we speak to, we think it's highly unlikely that you're going to see any post-sale replacement of animals and classic toxicology just because it's all about safety in a wholly animal model appears to be the best use—the best way to do that, but—and so to the extent to which the non-animal technologies ever get any traction, I think—that we think that's way off. Having said that, we're just going to do a lot of work, Dave, in all of this stuff. Study it, write about it, utilize it, talk to our clients about it, talk with regulators about it, and make multiple shots on goal with these potentially valuable technologies to see what really has traction. So we're going to continue to talk about it because we do think it's important. We do think it's possible in some domain, and we do think that if anybody is going to lead it, it really needs to be us.

DW
Dave WindleyAnalyst

Got it. Relatedly, one of the other areas that you had hoped, I think, to lead on was around this parentage testing and providence of animals. Is that still relevant? Or is that kind of faded and not strategically relevant anymore?

JF
Jim FosterChairman, President and CEO

I think that directionally, that's going to be important, not just for regulators, regardless of the country, but for ourselves just to know that and for our clients just to make sure that these animals are purpose-bred. So yes, it's going to be sort of slow going to get kind of a sense from government agencies that they like what we're doing. We actually found several places that we could do this on a cost-effective basis and really sort of nail down the fact that those animals are as we desire. We got out really fast working on it. I think the government is going to be a little more slow in their uptake of even having a conversation with us. But I do think that's something that again, Dave, that I think is essential. I think we have to have the leadership position there. I think that it's not very complicated by the way. As you know, we have this whole—the whole being able to identify the genetics—the specific animals is relatively straightforward science. It's a lot of animals, so it's not trivial from a cost point of view. But I think we can do it cost-effectively and whatever it is other going to pass it on. So we still, I would say, in the background, Dave, but we'll get back to it at some point, for sure.

Justin BowersAnalyst

Hi, good morning, everyone. So with booking—a two-parter for me. With the bookings stabilized and sort of if I look at the revenue and safety assessment for the first three quarters, does that seem like sort of a good run rate like on the go forward? And I just—if I look at what the guidance implies for 4Q, for example, and we adjust for the extra week last year, it sort of gets at DSA revenues flat, plus or minus Q-over-Q. So that's the first one. And then just with the improvement in the bookings that you're seeing, and I understand flow of cancellations. Is there any way to parse that out in terms of the nature of those cancellations and how it's sort of improved? Is it like— is it more less of the empty rooms versus programs that are in flight being canceled? Just any additional color there would be helpful.

JF
Jim FosterChairman, President and CEO

The reduction in cancellations is a good thing. I hope people are getting that. Because of capacity limitations, demand, availability of everything, including NHPs, and funding seemingly being better than last year and the year before, I think we had clients that were really worried that they wouldn't get a slot. And so they booked way out, which is some of that was good news and some of that was just booking a slot without a study. So that's disruptive, particularly when you get to the point of planning to set aside a certain number of animals and a certain cadre of staff, and then people can—and yes, they have a penalty when they cancel it. That was really great. So I think the normalization of cancellation, which, by the way, isn't always—cancellation and slippage is an obvious—is really a good thing. We're getting back to probably pre-COVID levels. And as we said a couple of times, it's always been there. And that's in the calculus of our forecasting and our guidance and how we plan for headcount and allocation held. So I think that's actually a good thing. I would stop short of quantifying what the growth rate of the Safety Assessment business is on a forward-going basis. It's a business where—we continue to be the market leader. We continue to get some price. We continue to get a significant amount of volume. I think we just said that we have a lot of stuff moving into the post-IND phase, which is fine, but we want both. Obviously, we're doing some IND work as well. But it’s important that we have both long-term studies and short-term studies. And I think what's happening is we're going to have a slow normalization of demand.

FP
Flavia PeaseExecutive Vice President and CFO

As I said earlier, we stand behind those three-year guidance numbers that we gave at our Investor Day. The sort of speed and cadence of all of this is not particularly clear. It hopefully will be a little more clear as we finish this quarter and talk to you folks in February about specific guidance for next year.

Dan LeonardAnalyst

Thanks for taking the question. I want to make sure I fully understand the direction of travel here in DSA, and I appreciate all the color on gross bookings. But specifically, I'd like your thoughts on at what point is the continued weakness in Discovery impact your outlook for safety?

JF
Jim FosterChairman, President and CEO

Hardly at all. So I understand why you asked the question. So our strategy and goal is very much that Discovery is a feeder for safety. So that's obviously the essence of your question so. It's a trivial part of the DSA revenue right now. Although we love the business, and we have good science and good parts and pieces, we're in an air pocket right now, but that's going to be transitory. To sort of refresh my answer to your question, if Discovery is rocking, that's beneficial to our safety business, particularly if we hold on to work. And just generally speaking. But I would say that it's kind of a tale of two cities. Our safety business is actually in this kind of funky economic environment is performing extremely well. We're getting price and share and lots of big studies, and our capacity is well utilized when I say capacity, both people and space. So as you think about the future, which I assume you are—and if you assume that Discovery's sheer pocket continues, and I don't know whether that's true or not, it will matter. It won't really fundamentally affect the size and scope and growth rate and our margin profile for the Safety Assessment business. And if it comes back strong, which, by the way, can be on very short notice or no notice, it just would be beneficial and add some incremental revenue to the sector. Also has, I guess last also has good margins. So I don't want you to forget that even though it's slower than we would certainly like the Discovery business has gotten nicely profitable, had wonderful growth rate last year, the year before and the year before that. And I think we're holding our own very well. But it's just—it's very simple. You've got clients, big and small, emphasizing post-IND preclinical work and clinical work just because they have to get some drugs to market to generate more revenue. That's—and that's sort of an always-always. But if they don't spend money on discovery, which, of course, is what they do, they don't spend money on Discovery, then they'll have nothing two years, three years, one year from now in the clinic. So it's not our opinion. It's a certainty that the pendulum has to swing back a little bit difficult to call because it's definitely related to funding and the overall economy. And I think it's related much less to the strength of the scientific modalities, which are going to be quite powerful. We got some really great drugs with these companies we're working on that are better life-saving. So we'll watch you. We'll let you know as soon as Discovery begins to come back. And as I said a moment ago, it will come back sort of surprisingly fast. Studies are short. We don't give a lot of notice on them. The turnaround time is pretty good, so is the pricing.

DL
Dan LeonardAnalyst

Appreciate that clarification, Jim. And if it's possible to ask an unrelated follow-up. I was hoping you could frame proportionately how much of your manufacturing business is driven by commercial products versus early-stage products that might be more subject to the reprioritization that you talked about on the call?

JF
Jim FosterChairman, President and CEO

Good question. So the CDMO business is all pretty much all clinical. So that's not manufacturing that stuff. So it's a little bit different than the rest. Yeah, I mean, a big piece of microbial is lot release for commercial products. So yes, for sure, and less stuff goes through the pipeline as less stuff is approved as they're trying to spend money in the clinic and maybe manufacture less of their other products. It slows down a little bit. Similarly, with biologics, that's also—we have to test those drugs before they go into the clinic. So just so I don't confuse you, yeah, a lot of stuff is focused on the clinic and going into the clinic, but less than they would otherwise like to go into the clinic just because they care. But we talked about the reprioritization of their pipelines. So even big companies, big pharma, who are well financed, have budgets, and they're very tight on the budgets, both in terms of headcount and other things. So we've definitely seen just a conservatism on the part of almost our entire client base who has—they have really good portfolios. They are just not developing and prosecuting their entire portfolios maybe the way they did in 2021 and 2022. Again, it's all transitory. So as stuff gets through the clinic and into the market, and when the economy feels better for these folks, I'm not an economist, so I have my opinion that kind of—it's not useful on this call, but I do think we'll start to see a lot more spending in discovery. But to answer your question specifically, you'll see a lot more testing of commercial products to go into the clinic.

TS
Tejas SavantAnalyst

Hey, guys. Good morning, and appreciate the time here. Maybe one on RMS, more of a cleanup really. Flavia, can you parse out that 460 bps decline in RMS margin across the NHP timing in China and the academic in-sourcing mix? I know you mentioned it was mainly the latter as far as top line growth. So is it fair to assume that, that sort of flows through to the margin sort of dynamic as well? And over what time frame do you expect to see a little bit of help from exiting the lower margin in sourcing contracts? I mean, is that a 2024 dynamic? Or is that more 2025 and beyond?

FP
Flavia PeaseExecutive Vice President and CFO

Hi, Tejas, how are you? So the RMS impact, both on top line as well as margin was a combination, as I said, of the lack of significant shipments of NHPs in China as well as a mix of businesses in our RMS segment. As you pointed out, we had a higher growth of some of the lower—on a relative basis, lower margin subsegments within RMS. So we expect that to continue into the fourth quarter. We're seeing, from a demand perspective, more resilience on the larger pharmaceutical clients and government contracts. So that plays into the margin. And then in the fourth quarter though, we will have NHP shipments. So the margin for RMS will pick up in the fourth quarter. I think we had telegraphed data or signal that in Q3, we weren't going to have any meaningful shipments and therefore, the margin was going to come down. So again, this is consistent with what we have been expecting. As far as the government contracts that we expect that we announced in the Investor Day, that are lower margin and that we would be exiting will likely start in the 2024 horizon.

TS
Tejas SavantAnalyst

Got it. That's super helpful. And then one on just the margin outlook here on a go-forward basis. Jim, I mean, obviously, you mentioned in your prepared remarks, manufacturing support is the biggest driver of margin expansion. Just in light of the 3Q headwinds here, what flattish margins next year be a fair additional assumption? I know it's a complex environment, but you also called out RMS seeing a little bit of macro headwinds here beyond China NHPs. So just any directional color for—sort of on 2024 margin trajectory would be super helpful. Thank you.

JF
Jim FosterChairman, President and CEO

I know it would be super helpful, but I have to wait until February to get that clarity, but I appreciate you asking.

FP
Flavia PeaseExecutive Vice President and CFO

Tejas, I would say, though, we still feel good about the 150 bps over a three-year period that we shared with all of you during Investor Day. The timing of that, as Jim said, it's not linear in that three-year horizon. And obviously, the main environment will play into that as we go into 2024. But we also, as I indicated in my prepared remarks, have also appropriately adjusted or started to ensure we are appropriately reflective of the current demand environment with some of the actions that we took already this year. So I'll let you take those pieces and make your estimates for 2024 until we provide guidance in February.

Hi, all. Thanks for taking our questions. To start, maybe I'll try to get at Derik's question from a lot earlier here, just in a different way. So your disclosures imply about $780 million of NHP-related revenue in 2023. How do the margins associated with this NHP work compared to your DSA operating margins this year? And how have the margins on that NHP work changed over the last few years as a result of the pricing increases on the NHP side? And then in terms of assumptions moving forward, I'd be curious to hear your take on what you actually have baked in for margins on NHP work as part of your midterm guide here, given your comments about pricing normalizing some here as we move forward. Thank you.

FP
Flavia PeaseExecutive Vice President and CFO

So maybe I'll start, and Jim can add. And I think I've—we commented on this over the last several quarters. NHP work, on a relative basis, has slightly higher margins than some of the other species more—we do. They tend to be more complex, sometimes longer. And so there is a mix impact that has been favorable as biologics had grown, and that drives higher demand for NHP work within our total study species work that we do. So that has been a tailwind. We don't know if that will continue or not, but that is unrelated to the discussions that we've been having on price. Jim?

JF
Jim FosterChairman, President and CEO

I think that's all.

MS
Max SmockAnalyst

Okay. Perfect. And then maybe just following up on Dan's question from a couple of minutes ago here. You mentioned the slowdown in discovery doesn't change your strategy in preclinical. But I just wanted to confirm that I heard you right, that we're not close to the point where the slowdown in discovery that we've seen over the last couple of quarters here starts to impact gross bookings and safety assessment.

JF
Jim FosterChairman, President and CEO

And ultimately, gross work is like the pipeline towards the clinical stage. Like when do you think do we get to that point? And when should we start to get concerned? I guess at the slowdown we've seen in discovery will start to impact preclinical more heavily and eventually clinical trial demand? Thank you. Don't be concerned. It's not the first time this has happened. When times are good, we see a balanced spending in discovery and development. That benefits our whole portfolio. When client base is concerned about revenues, they tend to nuance the clinic. And with regard to preclinical stuff, the post-IND stuff, and there before. And in terms of the growth in development and solidity and strength of the companies, they have to go back and spend a discovery. So it's just a matter of time, and it's impossible to call it, although we'll obviously have to call for our operating plan for next year. But as I said before, our discovery business, which we're pleased with the scale, pleased with what we put together is still trivial by comparison. So it's really going to have no impact on the growth of our safety assessment business any time soon. As I said before, positive about as we continue to work hard to have a flow-through for successful molecules for discovery safety, it could be a benefit, but I really don't see this being a detriment. I suppose if the business was much larger, and 90% of our clients were moving stuff from discovery to safety, I might give you a different answer, but that's—maybe we'll be there someday. It's not where we are right now. So I understand that they are connected, but it's actually useful to look at it on a connected basis. So what you see when we report DSA is essentially primarily our safety assessment results.

Charles RhyeeAnalyst

Thank you for taking the question. I had a question on the fourth quarter guidance, just generally how to think of cadence overall. I think pre-COVID, your fourth quarter was typically your strongest quarter in terms of earnings. Obviously, that wasn't the case during the COVID period and certainly not the case this year from tough comps, as well as some of the trends you're discussing. If we think about the range here for the fourth quarter, is this a good jumping off point, though, as we're going to the ex-COVID period? It seems like backlog is normalizing. Cancellation rates are slowing, and we're maybe getting to a more normal period. And so would we expect the jump-off point for the fourth quarter to think of first quarter next year at least sequentially down, and we'd be getting back to a more normal cadence of earnings?

FP
Flavia PeaseExecutive Vice President and CFO

It depends on what you mean by jump-off point from a growth rate, right? Our first—our fourth quarter, as I indicated in my remarks from an organic revenue, it's mid-single-digit decline, which is not, I think, how you should be thinking about the outlook for 2024. Without putting—without giving any guidance into 2024, we—I think the fourth quarter is being impacted by comps, because we had extraordinarily high performance in the fourth quarter of 2022 with close to 19% growth. So if you're talking about growth rates, I have to be careful.

CR
Charles RhyeeAnalyst

Right. Some color on from a dollar standpoint?

FP
Flavia PeaseExecutive Vice President and CFO

Yes. So I think from a dollar standpoint, I think I commented earlier, it's sort of flattish, I think, to slightly down versus the third quarter. Normally, our fourth quarter tends to be our largest quarter from a dollar perspective. But we do, as you pointed out, we've seen some impacts from the demand environment, and that plays a little bit into the fourth quarter. We really encourage you guys to look at us on an annualized basis. We have fluctuations quarter-to-quarter. There's comps when we compare to last year, first half, second half, as we pointed out. First half was relatively lower, second half was very strong from a growth rate, and then there's other things like the timing of the NHP shipments in China as I pointed out.

Hey, thanks for taking my questions. Jim, maybe starting with you. Can you give us a sense for how you're thinking about the Dynamics of bookings at this point? Not just in RMS, but across the business in terms of growth outlook for 2024? Any early signals of trends we should watch for in Q4? And more broadly speaking, are you starting to see any signs of stability in bookings or has that continued to be choppy?

JF
Jim FosterChairman, President and CEO

We are seeing some stability in bookings. I think the key is that a lot of clients are rationalizing and focusing on what they have to spend, but I heard some of the repeat clients getting back to a more normal cadence expected. So I think we are seeing some stabilization. As far as newer clients, I think there will be opportunities for some clients that legal and legitimate competitors can provide and those will benefit, certainly, but I think that a lot of the—you're taking advantage of growth is just going to be more focused. So you're going to see stability on one hand and opportunistic challenges on the other hand. But I think we will see stability from a standpoint of our biggest clients who are going to stay with us. I feel pretty good about that. I was hesitant at the beginning of the quarter to acknowledge points of stability, but I think we see movement back to some linear growth and some cadence on both sides.

Good morning, everyone. Glad to get in here. Just a quick one—you mentioned early signs of positive demand, particularly in the Safety Assessment segment. How would you frame that relative to the macro backdrop? Are you seeing that attributed to larger clients picking up spending, or are you seeing it on both the larger and smaller biotech front? Thanks.

JF
Jim FosterChairman, President and CEO

We feel we get some buoyancy from our larger clients who have already done good work with us. That—we've had a whole bunch of clients that have taken the top line as far as they can take it. I think that we have—especially given the normal rate of return; the small biotechs respect our costs and our business isn't immune to secondary market pressures. But that said, we believe there's some good dollars to be picked up with larger clients where they're going to get a disproportionately share of what would be overall growth within the biotech portfolio.
