Please note that in order to accommodate all individuals who wish to ask questions, there will be a limit of two questions at a time. I would now like to turn the call over to your host for today's call, Sondra Newman, Head of Investor Relations. Please go ahead, ma'am. Thank you, Operator, and welcome to our first quarter of 2024 report. On this call, we will cover business highlights and financial performance for the three-month period ending March 31st, 2024, and we'll provide financial guidance for the year. Joining us on the call today are Repligen's CEO, Tony Hunt, our CFO, Jason Garland, and our Chief Commercial Officer, Olivier Loeillot.

Adjusted non-GAAP figures in today's report include the following: book-to-bill ratio, organic revenue growth, base business revenue, which excludes COVID and M&A, non-COVID revenue, cost of sales, gross profit and gross margin, operating expenses, including R&D and SG&A, income from operations and operating margin, other income, pre-tax income, effective tax rate, net income, diluted earnings per share, as well as EBITDA, adjusted EBITDA, and adjusted EBITDA margins. These adjusted financial measures should not be viewed as an alternative to GAAP measures, but are intended to best reflect the performance of our ongoing operations. Now, let me turn the call over to Tony Hunt. Thank you, Sondra, and good morning, everyone, and welcome to our Q1 earnings call. As you saw in our press release this morning, we delivered a solid first quarter on revenue and orders. With Q1 revenues coming in at $151 million, we are right on track to delivering $300 million-$310 million in the first half of 2024. Orders were in line with our expectations, resulting in a book-to-bill of 0.99 in the first quarter and 1.03 over the past nine months. We're satisfied with these results, especially in light of tough sequential and year-on-year comps and the known headwinds in COVID, proteins, and China. During the first quarter of last year, 2023, we realized $23 million of COVID-related revenue, none of which was recurring. As we shared with you on our February call, we anticipate proteins headwinds of over $30 million in 2024, which we saw play out during the first quarter. Importantly, we continue to see signs of recovery in the market and feel confident that the destocking challenges are behind us for the most part. Our confidence is reinforced by what we are seeing in filtration performance, consumables demand, and new modality momentum. In filtration, our largest franchise, year-on-year, non-COVID filtration orders were up 20% in Q1, and revenue was up by more than 10%. We also saw a nice sequential uptick in non-COVID filtration revenue of greater than 15%. Regarding consumable orders, where destocking has been the most pronounced, we've seen a positive uptick in demand outside of proteins. For the first quarter of 2024, these consumable orders increased by more than 10%, both sequentially and year-on-year. Both sales and orders from new modality accounts were another area of strength, at levels higher both sequentially and year-on-year. New modality revenue growth in the first quarter of 2024 was greater than 15% compared to the first quarter of 2023, and orders were up 8%. While encouraging, these positives were offset by the aforementioned weakness in proteins and capital equipment purchase constraints, as reported across the industry. Our expectation is that markets will improve as we go through the year with stronger order trends in the second half, and so revenue guidance range is unchanged for 2024. For the quarter, our overall revenues were down $31 million or 17% year-over-year, driven primarily by the $23 million decline in COVID-related revenue. Our base business revenues were down approximately 9% in the first quarter, reflecting the anticipated decline in proteins and partially offset by filtration sales, where our ATF business had a very strong quarter. Overall, non-COVID orders were flat year-over-year. Within our franchises, proteins orders were down 30% as expected, which was more than offset by an approximate 20% increase in filtration demand. Excluding proteins, orders as reported from our non-COVID filtration, chromatography, and analytics franchises were up 7% year-over-year and up 13% when you compare the last six months' performance to the prior six-month period. Overall, order dollars are consistent with what we observed in the second half of last year, while covering the drop-off in proteins. At a customer level, pharma orders were in line with Q4 and up greater than 10% year-on-year. CDMO orders were down year-on-year and sequentially. Some of the softness can be attributed to lumpiness in orders from a few of our larger accounts, but it's fair to say that at this point, we're not seeing a true sticky rebound from CDMOs. The good news here is that when we take a look at the last six months versus the previous six months, both CDMO orders and pharma orders are up about 10%. New modality orders were also strong, up high single digits in Q1 versus the corresponding period last year. As noted on our February call, strength in new modalities is directly tied to our top 20-25 accounts, who are scaling with our technology. Strategically, Q1 was another good quarter for the company. Our latest acquisition in the fluid management mixing space, Metenova, had a strong quarter for revenues and orders. Our collective teams continue to work through the integration plan with a focus on managing a broader network of distributors and new product development. In fact, we just launched our first bag and film technology into the single-use bag market, paving the way for the launch of our single-use mixers in the second half of this year. In addition, our R&D team successfully developed and launched the industry's first fully automated GMP-ready filtration system, called RS 10. The feedback at the INTERPHEX Conference earlier this month on these two new product launches was incredibly positive, and we expect the system for mRNA in cell and gene therapy processing to have a meaningful contribution in 2024. We are clearly executing on our strategy to differentiate ourselves in the market with best-in-class systems and follow-on consumables. So moving now to our quarterly performance. The story of the quarter was the performance of our filtration and fluid management businesses. Our filtration franchise had a very strong quarter, with non-COVID revenue growth of more than 10%. As mentioned earlier, this was driven by the success of ATF, where we have been specified into nine late-stage and commercial processes since mid-2023. The impact of these late-stage wins drives more consistency in consumables and should be a key driver of growth for this business over the coming years, especially as many of these drugs are in the ramp-up phase. In addition, the fluid management business had a good quarter for both revenue and orders. We are seeing some very positive signs as our investments in this area are beginning to pay off. In chromatography, our OPUS pre-packed column business had a solid quarter, slightly up on revenue versus Q4. The opportunity funnel is strong, and we expect further growth in revenues here in Q2 as this business continues to recover from the resin shortage challenges in prior years. A major driver of growth for us is the continued uptick in OPUS demand in the new modality markets as more customers switch to the convenience of pre-packed columns versus self-packed. Our analytics business had a slower start to the year, mainly driven by fewer dollars for capital equipment purchases. This is consistent with what we have seen for this franchise over the last few years. Again, our funnel of opportunities is strong. There continues to be strong demand for FlowVPX and real-time process management, or RPM, and we continue to see these technologies as the drivers of growth for analytics here in 2024. Finally, we had a weak quarter in proteins. Revenues were down both year-on-year and sequentially, as Cytiva demand dropped to essentially zero. And as we noted in February, another partner is burning off inventory, which also impacts our performance. The Q1 decline in proteins is in line with our guidance for the year of 30%-35% drop-off in revenues. However, we continue to expect growth in filtration, chromatography, and analytics as previously guided. In summary, we're off to a good start here in 2024. We believe that destocking is essentially behind us. We see positive trends in consumables, and our orders are holding steady, staying 2%-3% ahead of sales over the last nine months. Our guidance is based on our expectation to see orders pick up in the second half of the year. We remain confident in the medium to longer-term potential in bioprocessing, with stronger growth in view for 2025. With that, I will hand it over to Jason for a financial update. Thank you, Tony, and good morning, everyone. Today, we reported our financial results for the first quarter 2024, and left adjusted financial guidance unchanged for full year 2024. Revenue in the first quarter was down $4 million sequentially from a strong fourth quarter, driven primarily by the expected headwind from proteins on lower affinity ligands and resin demand. We delivered total revenue of $151 million in the quarter. This is a reported decline of 17% year-over-year, or down 20% on an organic basis, with acquisitions contributing 3% of our reported growth and currency with nearly a 1% headwind. As Tony mentioned, for the quarter, our base business, which excludes COVID revenue and M&A, was down 9% on lower protein sales. We recognized $23 million of COVID revenue in the first quarter of 2023... and approximately $6 million in M&A sales in the first quarter of 2024 from our 2023 acquisitions. Therefore, our base sales were $145 million in the first quarter versus $160 million in the prior year. Tony shared color on our franchise performance, so let me quickly highlight the performance across our global regions. For context, in the first quarter of 2024, North America represented approximately 49% of our global business, while Europe and Asia Pacific, and the rest of the world, represented 33% and 18%, respectively. For our non-COVID business in the first quarter, North America was up on strength across all franchises except proteins, and Europe was slightly down, with the decline in ligands being offset by strength in filtration. The decline in Asia Pacific and the rest of the world was driven by continued weakness in China. First quarter 2024 adjusted gross profit was $74 million, a 27% decrease year-over-year, while delivering a 48.6% adjusted gross margin on $31 million of lower revenue. The year-over-year reduction in gross margin of over six points reflects roughly 4.5 points of mix headwind from the high COVID sales in the first quarter of last year, with the remainder tied to reduced volume. Our gross margin remained roughly consistent with our fourth quarter 2023 exit rate, down about 50 basis points on slightly lower volume and consistent with achieving our 2024 total year guidance of 49%-50%. As we have shared before, we remain focused on cost management and ensuring we have the right balance of resources. We continue to execute restructuring actions, and we'll remain diligent in our spending, investment prioritization, and we remain focused on driving productivity and efficiency across our manufacturing network. As an update, we incurred just over $1 million of restructuring charges in the first quarter, down from the $8 million of charges in the fourth quarter. This was mostly driven by severance and facility exit costs. All these charges are non-recurring in nature and are only reflected in our GAAP P&L for all periods. Though our current restructuring plans are coming to an end, we will evaluate the need for future discrete actions as we continue our margin expansion journey. Continuing through the P&L, our adjusted income from operations was $12 million in the first quarter, down $29 million compared to prior year, driven by the $27 million dollar drop in adjusted gross profit just described, with an additional $3 million dollar increase in adjusted SG&A and a $1 million dollar decrease in adjusted R&D as we manage the timing of our technology investments while continuing to introduce innovative new products. The increase in adjusted SG&A is driven by $2 million from both our acquisitions that closed after the first quarter of 2023. SG&A is also impacted by the annual increase of salaries. Sequentially, OpEx was up $4 million in the first quarter of 2024 versus the fourth quarter of 2023. This also includes the impact of annual salary increases, higher stock-based comp, and the timing of external service fees. In the fourth quarter, stock comp benefited from grants dissolving with employee exits, which did not repeat, and in fact, was offset by new grants in the first quarter. Our first quarter 2024 operating income margin of roughly 8% includes about a five-point headwind from depreciation, which had been a four-point headwind in the same 2023 period. This is reflective of the critical investments we have made in capacity. Year-over-year, operating income margin is primarily driven by roughly nine points of negative mix at the operating margin level from COVID sales last year, and about a seven-point drag from volume deleveraging on OpEx and our fixed capacity structure with the lower sales. Both of these are partially offset by nearly two points of net year-over-year cost initiative benefits. Our first quarter 2024 EBITDA margin rate was approximately 13%, which excludes the drag of the increased depreciation. Adjusted net income for the quarter was $16 million, down $20 million versus last year. This was driven by the $29 million dollar drop in adjusted operating income, offset by $2 million of higher interest income, net of interest expense from improved interest rates on our cash position, and approximately $6 million less tax provision. Our first quarter adjusted effective tax rate was 18.7%. While the rate in the quarter includes a discrete benefit from stock-based compensation, the total year adjusted effective tax rate is still on track for 21%, as guided in February. Adjusted fully diluted earnings per share for the first quarter was $0.28, compared to $0.64 in the same period in 2023. Finally, with the strong generation of cash flow from operations in the quarter, we increased our cash position to $781 million, up $29 million from the end of 2023. I'll now move to a quick update on our guidance for the full year of 2024. I'll speak to adjusted financial guidance, but please note that our GAAP to non-GAAP reconciliations for 2024 guidance are included in the reconciliation tables in today's earnings press release. For further clarity, our guidance is fully inclusive of the FlexBiosys and Metenova acquisitions we made in 2023. In summary, we have made no changes to the total year adjusted guidance ranges that we shared in February. Running quickly through the P&L, our revenue for 2024 is expected to be in the range of $620 million-$650 million, while we continue to manage three key headwinds: COVID, proteins, and China. We expect 2%-7% growth for our non-COVID business, with M&A contributing three points of that growth. As a note, we will not be reporting on COVID sales in 2024, as this will be de minimis. We expect revenues in the first half of 2024 to be better than the second half of 2023, and we expect revenue for the second half of 2024 to step higher again. We expect to deliver adjusted gross margins in the range of 49%-50%, essentially flat to 2023. To summarize, in February, we see about 200 basis points of headwind from mix with our reduced proteins forecast, salary increases, material inflation, and from resetting our incentive compensation back to normal levels for our employees in 2024, after being far below that in 2023. The impact from these headwinds is expected to be entirely offset by the manufacturing productivity, which is forecasted to generate roughly 200 basis points of year-over-year adjusted gross margin rate improvement. We still assume price will be flat for the year, though we will raise prices selectively. We expect our adjusted income from operations to be between $83 million-$88 million, or 13%-14% adjusted operating margin rate, which is down about 100 basis points at our midpoint versus 2023. In our adjusted income from operations, we see line of sight to delivering 400 basis points of year-over-year productivity. However, total salary increases, material inflation, mix from lower protein sales, and volume deleverage creates greater than 300 basis points of headwind. The headwind from resetting our incentive compensation is a total of approximately 200 basis points of headwind at the adjusted income from operations level, with the majority of our incentive comp costs in SG&A. As discussed earlier, we remain focused on optimizing our cost structure while protecting the resources and investments needed to grow long term. As our volume grows, we expect profitability to grow with it. Adjusted EBITDA margins are expected to be in the range of 18%-19% for the year, reflective of the exclusion of roughly 500 basis points of headwind from fixed depreciation costs from the critical capacity expansions we have made. Continuing through the P&L, we expect our adjusted other income to be between $18 million and $19 million. We will continue to monitor the progression of interest rates and update this outlook as appropriate through the year. Our 2024 adjusted effective tax rate is expected to be an estimated 21%. Incorporating all of these items, we expect our adjusted earnings per share to be between $1.42 and $1.49, down 33-26 cents, respectively, versus last year. As we wrap up, let me state that we will remain laser focused on the execution of our strategic priorities: continuing to expand our position in top accounts, delivering more innovation with differentiated new products, building off our wins and new modalities, successfully integrating Metenova, and remaining diligent on our cost control and productivity to support increase in margins as we go through the year. With that, I'll turn the call back to the operator to open the lines for questions. Yes, thank you. We will now begin the question and answer session. To ask a question, you may press star, then one on your telephone keypad. If you are using a speakerphone, please pick up your handset before pressing the keys. If any time your question has been addressed, and you'd like to withdraw it, please press star then two. At this time, we will pause momentarily to assemble the roster. The first question comes from Rachel Vatnsdal with JP Morgan. Perfect. Hi, good morning, and thanks so much for taking the questions. So first up, I just wanted to ask on some of the trends that we're seeing here in China. Obviously, we have some of the headlines regarding the BIOSECURE Act. You also called out some of the lagginess from CDMOs. So can you just walk us through what are you seeing there from a customer perspective and conversations? And then also, just in terms of your expectations on the year, how are you thinking about China in terms of how it'll end? Thanks so much. Yeah. So thanks, Rachel. I'll start a little bit on this, and then I'll ask Olivier, who's joining us today, who's you know spending a lot of time out in the region, to also comment. But in general, I think what we're seeing is continued weakness in China. The CDMO market, which had some very positive kind of order trends in Q4, didn't repeat in Q1. And so it's just not out of the woods yet in terms of where CDMOs are at. Pharma, of course, has been much more positive. Maybe, Olivier, would you like to comment a little bit on kind of the China situation, what you're seeing and a little bit on the CDMO pharma? Yeah, absolutely. So as Tony just mentioned, we don't really see any improvement yet on the China market side. As you mentioned, obviously, there are two potential factors happening right now: the BIOSECURE Act, which is a little bit too early to say whether it will impact or not, and we work with most of the big pharma CDMOs, meaning like wherever the product ends up really doesn't matter for us. In terms of the China stimulus, the scope is very broad right now, so we are also waiting to hear how this will be implemented, and we are staying very close to our customers. Great, thank you. And then just as my follow-up, nice to hear the strength in the portfolio ex proteins and equipment this quarter, but I just wanted to dig into some of the protein weakness a bit, a bit more. So I believe you mentioned that orders on proteins were down 30% this quarter. Can you just walk us through, how did that land relative to your expectations? And then in terms of the cadence of the protein headwinds throughout this year, has anything changed in your assumptions? And, you know, what should we expect in terms of the exit rate for proteins this year? Thank you. Yeah, thanks, Rachel. Look, on the protein side, when we got together back in February, we said down about 30%-35%. It's exactly in line with what we were expecting. I think in a lot of the follow-up calls, we were saying probably around that $8 million per quarter, that range, and it's exactly in line with that. And if you look at the orders in Q1, and you actually just take proteins out, we're pretty much in line with what we saw in Q4, ex proteins. So it is what we were expecting. There's nothing has changed, and we expect to be down 30%-35% at the end of the year. Thank you. The next question comes from Jacob Johnson with Stephens. Good morning. Maybe, Tony, just thinking about orders a different way. Can you just talk about how orders trended throughout the quarter and any commentary you'd like to give about April, if possible, as we think about just any kind of signs you'd point to to support the view that orders will continue to pick up in the back half of this year? Yeah, I'm smiling. Thanks, thanks, Jacob, for the April question. But yeah, I would say that we were very similar, I think, to most of our peers with, you know, January being somewhat of a lighter month, and then February and March were actually pretty strong, and that's how we ended up where we were with, you know, a book-to-bill of 0.99 and covering off a fair amount of the protein shortfall. You know, April has come in from pretty much close to where we would have expected it to come in. You know, I think when we look overall at where we need to be, we need to see pick up in orders as we go through Q2 and through Q3 for us to hit the second half of the year targets. I think that's the expectation. There's some real nice positive signs that we're seeing. I mean, like the consumable trends in Q1, that is something that, you know, is really, really positive, because that really points to the fact that the destocking piece is more or less behind. The troublesome parts and the annoying parts are really the, you know, the CDMO market not fully rebounded, you know, dealing with this weakness, continued weakness in China. And, you know, I know a number of our peers talked about the capital equipment side of the market. And yes, we were no different. We saw weaker capital equipment, but Q1 is typically a slower quarter for capital equipment anyway. So that's kind of what we see, Jacob. Got it. Thanks for that, Tony. That last comment, I guess, is what I wanted to follow up on. You know, the weakness in capital equipment, you know, you've been on this journey to build out a systems portfolio. Does anything about the current kind of capital equipment demand environment impact the trajectory of those efforts, or is it just kind of seasonality? Yeah, I'll start, and maybe have Olivier talk a little bit about kind of one of the launches we made this year, which I think becomes a really important launch for us. I would say that, you know, the capital equipment market, you know, when you finish off a year like 2023, and you can go back over the last five, 10 years, there are, you know, you definitely have dollars at the end of the year that people spend, and then the budgets are set, but some of the dollars don't get released. So we think it's more of a dollars getting released, as opposed to any real sort of bigger issue that we should be worried about. Now, we've, as you noted, we've spent a lot of time over the last four years building out a, you know, a capital equipment portfolio, systems portfolio, and we're wrapping a lot of our consumables, whether it's on the fluid management side, or it's on our, you know, filtration consumables, into those systems. We've made a lot of progress and, you know, Olivier joined back in, October of last year, and he spent a lot of time out in the field. Maybe, Olivier, do you want to chat or talk a little bit about the, you know, the more recent launch and what you're seeing with capital equipment in the market? Yeah, no, absolutely. So we just launched a new product called RS 10, which is a very unique bench-scale TFF system. I mean, I've hardly ever seen so much traction on the launch in the last several years. One of the reasons being, like, it's really for low volume type of application, and this is perfect fit for the new modalities like mRNA and gene therapy. So we great traction on that side, and we expect it to be generating significant sales already this year for us, so. Got it. Thanks for taking the questions, guys. Thank you. And the next question comes from Puneet Souda with Leerink Partners. Yeah. Hi, Tony. Can you hear me okay? ... Yeah, yeah, we can hear you, Puneet. Okay, great. Okay, so, just, first one on book-to-bill, and then I have a follow-up. I mean, it appears that proteins is where the challenges are, but you have pointed about proteins challenges for the last few quarters. So just wondering, you know, if there's a book-to-bill number that you have here for ex proteins and overall, you know, leaving proteins aside, you know, when you look at the overall sales funnel, I think you talked more about that last quarter as well. So wondering, you know, what you're seeing there in the sales funnels, you know, as we head into this sort of second half of the first part of the year. Okay. Yeah, look, when I look at the book-to-bill, I don't have the book-to-bill for ex-proteins in front of me, but I think the way to look at this is honestly to look at it on a nine-month basis. So if you look at our book-to-bill over the last nine months, it's 1.03. I think that's a healthy sign, right? We're about 2%-3% ahead of sales in terms of orders. And you know, we've known, as you know, we've chatted and we've had conversations with investors and analysts on this. We've known about the proteins headwind, so, you know, that $8 million per quarter challenge, we're trying to make up for that in terms of strength in consumables and strength in our products and new modalities. You can see, you know, our biggest franchise, which is filtration, up 20% on orders year-on-year, and then up 8%-10% on sales. So it's very encouraging. There's just a little bit of chop and noise still in the market that's getting flushed out, and we expect as we go through the year that that begins to improve. The sales funnel, you know, I think what's interesting about the sales funnel is, you know, we've talked a lot about that over the last 12 months. You know, year-over-year, sales funnel continues to be up. I would say if we looked at the percentages, you know, what's that 50 versus 75 versus 90. 75% and 90% part of our funnel is pretty much unchanged versus what we saw at the beginning of the year. 50% is down a little bit, but we have a lot of, you know, new opportunities that have entered into the funnel. So, we think it's, we have the right funnel to deliver on what we need to deliver in 2024. Got it. And then just a follow-up on the CDMO side. You said, you know, CDMO stickiness is not what you would have seen before or expected. Just can you elaborate a bit more on that, and what do you mean there in terms of the overall recovery within the CDMO? Is there something fundamentally different there? Yeah, I'll start, and I'll have Olivier, because he's spent actually a lot of time over the last quarter and a half, actually out visiting not only the key pharma accounts, but also the key CDMO accounts. For me, you know, the CDMO customer base really is, you know, what we're seeing is more around lumpiness within certain accounts. If you actually look at kind of the long tail of outside the top ten CDMOs, it's pretty consistent over the last couple of quarters in terms of revenue and orders. We're just seeing a little chop in the top ten accounts, and so it bounces up and down, and therefore, based on how that moves, you can have stronger quarters or weaker quarters. But maybe, Olivier, do you want to chat a little bit about what you're seeing in the marketplace? You know, absolutely. I would just add that the good news is the last six months order with CDMOs have been 10% higher than the previous six months of orders. So where we are still not where we would like to be with CDMOs, at least we've started to see some improvements. So there are also quite a lot of moving pieces right now, or potential moving pieces with the recent acquisition of Catalent by Novo, and also the potential implementation of bi-- so of the BIOSECURE Act, which mean that probably some of the projects are, are moving from one CDMO to the other and so on, and it might be also turning a little bit of side note for the time being. Okay. Helpful, guys. I'll hop off. Thank you. The next question comes from Dan Arias with Stifel. Morning, guys. Thanks for the questions. Tony, maybe on chromatography, I think your phrasing was that the business continues to recover from the resin shortage. Is that to say that the market is still a bit constrained by supply, or, or is it back where it needs to be? And then just assuming that you are in better shape than you were last year, is it fair to think about chrome growing a little bit this year? I mean, I think the outlook was for 0%-5%. It seems like the low end of that is less likely, but maybe I'm not considering something. No, I would say that when we look at the chromatography business, the supply challenge is definitely behind us. I think both, you know, the main players on the chromatography resin side have built capacity, and lead times are essentially back to where we would have seen in the pre-COVID days. So I think that's really a non-issue. I think we're, you know, when you look at our chromatography business and you kind of say: How does it split up? I mean, it's a... I don't know if it's exactly 50/50 CDMOs and pharma, but obviously you can imagine the pharma side is, and small medium-type biotech is doing well. And then CDMOs is, you know, we're still waiting for some recovery there. So it's a little bit of that that slows it down, but we're thinking the 0%-5% is pretty solid for the year. Dan, is there some upside? I think that will really come from an order uptick that we were looking to see in the second half of the year. What's very encouraging for us is, you know, if I went back two years ago, we looked at the new modality space two years ago, and we were surprised that we weren't getting as much traction with the OPUS pre-packed column in that space, and we put a real effort on it, and now we're really seeing the traction. And we're getting a lot of companies that typically would say, "Hey, look, we'll pack our own columns." They're looking to the convenience of getting self-pack from us as a service. I think that's, if I had to look to an area where we would see growth, it's probably continued growth in new modalities and then a pickup in the CDMO side that could get you to the higher end of that 0%-5% growth. Yep. Okay. And then, Jason, maybe on EBITDA margins, anything from a cadence standpoint that's noteworthy, or is it sort of fair to model sequential improvement across the year as the volumes ramp in order to get to that 18%-19%? And then you, you touched on the fixed cost element. When we think about the leverage you can pull this year versus what's more for next year, can you just maybe make a comment on OpEx cost containment versus what might need to be done on the production side? Thanks a ton. Yeah, great. Thanks, Dan. Look, yeah, I, I think we've, we've been. We've tried to be clear that our profitability would be increasing with volume through the year, and to your point, that's certainly how we see this playing out, you know, especially with the second half step up over the first half in aggregate. You know, we'll see. If you look at kind of the where we're at for first quarter, 8%, to get up to the guidance of 13%-14%, you know, that's scaling up about five points. Well, I think to answer some of your questions, we'll get probably one to two points of that from higher gross margin, you know, both through a little bit of leverage, but mostly through the cost actions and profitability actions we're taking. We'll get, you know, two points of straight volume leverage on that OpEx, right? So just OpEx content, and then, as you can imagine, we'll then get the rest through further reductions and reduction programs for OpEx. So, you know, we're continuing to execute that, and to your point, really, the higher volume with the higher volumes in the second half, we'll see that profitability step up. Okay, thank you. Thank you. The next question comes from Conor McNamara with RBC Capital Markets. Hey, guys. Thanks for taking the question. Tony, just getting back to the book-to-bill. One of the things you highlighted was that a book-to-bill greater than one for the last nine months versus, you know, 0.99 for the quarter. So I'm just curious if there was anything else in Q1 around seasonality or higher cancellations or just timing of equipment that gives you confidence that you know, you should be above one for the rest of the year? Yeah. So on the Q1, I don't think there was anything unique in Q1 or different in Q1 versus, say, what we've seen over the last three or four quarters, besides what we kind of highlighted in proteins. I mean, if you take the proteins out, then, you know, you can see the impact on orders between Q4 and Q1 is purely the proteins piece. Now, you can look at any portfolio, whether it's us or any of our peers, and you're going to have lumpiness in different sections or segments of the market. So for instance, you know, in Q4 versus Q1, we had stronger consumables in Q1 versus Q4, but we had weaker capital equipment. You know, we were stronger in Asia, you know, including China in Q4 and weaker in Q1. And so when it all kind of balances out, it's, it comes in around the same number, right? And, yeah, no, look, we need to see, you know, increased traction. So the goodness we're seeing in consumables, it's got to continue. We've got to see a bounce back in the capital equipment side. We've got to see CDMOs also beginning to rebound a little bit more. And of course, we're all, you know, as you know, we're in a bit of a unique position as a company because while everybody's dealing with COVID as a headwind, we've got proteins headwind. While everybody's dealing with COVID and China's headwinds, we've got the additional headwinds, which is proteins. So it masks a little bit of the goodness that's going on in the portfolio. Got it. Okay, makes sense. Thanks for that. And then just on margins, can you comment on what the margins are on the proteins business, if there's anything else as far as mix that impacted the gross margins this quarter? You know, equipment's weak and consumables strong, or anything else worth calling out as far as the margin mix. Yeah, I mean, look, the proteins is certainly above average. I think the other thing, too, to keep in mind is both on a year-over-year, first quarter to first quarter basis, $23 million of COVID sales at very high margins last year in the first quarter. And then when you look at it sequentially from fourth quarter 2023 to first quarter 2024, again, $8 million of COVID revenue in the fourth quarter at high margins. So, I think it's more of a this COVID dynamic in terms of some of the margin changes you do on a comparable basis, and less so maybe proteins. But certainly that's a drag for us as well as through the year. Got it. Okay. But the, the proteins is above average. I guess that was the, the bigger question, so thanks for that. Yes. Yep. Yeah, absolutely. All right, thanks, thanks, thanks for the questions. Appreciate it, guys. Thank you. The next question comes from Matt Larew of William Blair. Hey, good morning. Sorry, another one on CDMOs. It sounds like, given, Tony, your comments around the lack of destocking, that it's not sort of an inventory work down issue and maybe more of an activity issue. So I guess, just curious, if you were to break out- ... you know, either your own orders or just conversations with CDMOs, is there any way to cut it, you know, from a modality perspective, early stage, late stage perspective, just to help maybe, you know, give us confidence on whether orders return throughout the year? At the CDMO level, Matt? Yes. For CDMOs, good question. Yeah. Look, as I said earlier, I think what we're seeing is more lumpiness at the top accounts. And of course, the, you know, we, we know that for the tier two, tier three CDMO players, that the small biotech companies feed into that. And look, it's encouraging to see the biotech funding returning, right? And it's also encouraging to see that we, you know, the industry had a strong start to the first quarter in terms of number of drugs approved, right? I think there were six mAbs, five biosimilars. There were three or four gene therapy drugs. So that's actually at a pace that's been better than we've seen in prior years. All of that is going to help the CDMO market, right? Because a lot of those smaller, medium-sized biotech companies turn to the CDMO industry to do that. And for us, like, we were also encouraged when you look at the mAb side. I think we were in two-thirds of those mAbs that got approved with products from Repligen. So it's a, you know, again, leading indicators that we like, and, you know, we'll see as we go through the year how it all plays out. Okay, thank you. That comment actually maybe feeds into my next question, which is, you referenced, filtration non-COVID revenue up 10%, driven by ATF, and you said nine late-stage and commercial processes since mid-2023. Could you maybe give us a little context in terms of that number relative to, you know, the total number of late-stage commercial processes, or perhaps how that number would compare to a typical year or a typical period in terms of your involvement in late-stage and commercial with ATF? Yeah, let me start, and I'll have [Daphne] and Olivier talk through some of the nuances of the nine late-stage drugs that we're in. But, you know, ATF is, I would say that Repligen as a company, right, we have, you know, 35% of our revenue coming from commercial, 65% of our revenue coming from clinical. So, you know, we've been working obviously on many of these product lines, whether it's ATF or it's, you know, our consumables, like hollow fibers, flat sheet cassettes. So we would expect that we would see more approvals coming through. But that's a high number of approvals to get in a short period of time. And I can say that just having worked myself at other companies in this industry over the last 25+ years. But maybe, Olivier, do you want to speak a little bit to kind of how the nine split up between mAbs and vaccines so people can get a sense of what we're talking about? And to that, I would just add that indeed, we started that ATF journey several years ago and so on, and it's really great to see how we're collecting the fruits right now, because these nine projects we've been, like, designing recently, which are anywhere between phase three or commercial phase, are added to another set of several tens of products where we were already designing. And as Tony just mentioned, this is really across the board. I mean, it's really from the vaccine side to monoclonal antibody, and more recently, indeed, within the cell and gene therapy arena as well. So we really have great traction, and the best is yet to come for ATF, because indeed, when those products move toward commercialization, volume typically increase significantly. Thank you. Thank you. And the next question comes from Matt Hewitt with Craig-Hallum Capital Group. Good morning. Thanks for taking the questions. Maybe first up, with the new bags that you're launching, what will that mean for the Metenova single-use technology? I mean, has that been a gating factor or, you know, and therefore, getting the bags launched will mean that that can be a driver later this year? Or how should we be thinking about that? Yeah, I'd say it's not quite impacting Metenova yet. You kind of have to have the bags in the market. So when we did the FlexBiosys deal a year ago, the thought process was they also accelerate the commercialization of a Repligen film/bag. So that's what's happened. The next phase actually does involve Metenova, because we want to get out in the second half of this year, like, this mixing technology, which would be single-use mixer. And Metenova, as you might recall, has been very much a stainless steel repeat-use type mixing technology. And so now this gives us a single-use mixing portfolio. But to be able to do that, you needed to have the bag. We have the bag, now we marry it up with single-use impeller technology from Metenova, and we get that into the marketplace in the second half of the year. Got it. And then kind of separately here, and I realize the BIOSECURE Act, it's -- there's still a question where it's going to go from here, and even if it is ultimately made law, that it's really a zero-sum game for you. But with, you know, there's already been some pharma companies that have come out and said that we're already having discussions about moving some of our production around. Does that create a little bit of a lag where CDMOs in particular, but even pharma companies, are trying to figure out, okay, well, if we have to move from, you know, CDMO A to CDMO B, but we don't know the timing, is there any risk that that creates a timing lag, so maybe it exacerbates the lumpiness over the next couple of quarters? Or how should we be thinking about that? Thank you. ... Yeah, and Olivier did a nice job of kind of giving everybody an overview of where the BIOSECURE Act is at. We just don't know the answer. And you know, we've had lots of questions on this, as you can imagine, over the last couple of months. I think it's wait and see, but if it were to pass and there were changes, then yeah, there would be some tech transfer lag that would probably happen. But let's see how this all plays out. We're focused on serving our customers and making sure we get products delivered on time with the highest quality. And you know, we're in processes, we'll stay in the processes. That's our view. Understood. Thank you. Thank you. The next question comes from Paul Knight with KeyBanc Capital Markets. Hi, Tony. I know you haven't been involved in GLP-1s. Is there any way you could be with product development? And then the last question or second question would be: What portion of the OPUS pre-packed column market, so to speak, is still home brew, half, or what's the level of that? That's a great question. On the OPUS pre-packed column, I would say that the vast majority... I'll, I'll answer that question first, but the vast majority of the CDMO side of the industry has moved to pre-packed columns. And I would say the smaller, medium-sized biotech companies have also moved to pre-packed columns. I would say large pharma is a bit of a mixed bag. You have some large pharma companies that really embrace, having the, flexibility of getting pre-packed columns delivered when they need them, and you have, a still a significant number of pharma companies that, you know, "We know how to pack our columns. We pack it ourselves. We do a good job. We're not interested." But it's a bit of a slow, a, a slow grind. One of the things, maybe Olivier can talk about is, you know, with the implementation of our key account management structure, that is one of the focus areas that we have. And maybe we'll chat about that in a minute. But on the GLP-1s, that we do play a little bit in it, but it's just not big enough for us to call it out as meaningful. But you can imagine technology like, you know, our component side, mixing side of what we do in fluid management. There's definitely some involvement there. We're we continue to look to see the areas where we can play, but, you know, for us, at least today, it's not a big play. Maybe, Olivier, do you want to chat a little bit about kind of how the key account management team is focusing on, on the pharma side for pre-packed columns? You know, actually, and just maybe to add one point to your question on OPUS specifically, the big difference between CDMOs and pharma is pharma, they know in advance what product, they will have to manufacture over the next 12 months. CDMO don't always know, which is why they love OPUS, because then they have a set of, columns ready to use for whatever product they might catch, in the next six to 12 months. Yeah. But back to key account management, as you know, we've built that team about a year ago. We're really happy about the progress we have on that side, and we are really covering both big pharmas on one side and the top CDMOs as well on the other side, and to make sure, like, we are capable to offer the A to Z offering we have in the portfolio today. Thanks. Thank you. And the next question comes from Justin Bowers with Deutsche Bank. Hi, good morning, everyone. So a couple questions. Just one, on the, on the CDO comments—CDMO comments and, and the sort of the lumpiness you're seeing there, is that, is that more around equipment sales, or is it just fits and starts in terms of, of, ordering patterns? And, and the gist of it is like, how close are we or are we back to normal order, ordering patterns and, and is this just sort of like the, the post-COVID norm? And then the, and then the second part is, on your comments about beginning to see CapEx come back, is that, is that more targeted towards CDMO or, or new builds or, or sort of replacements? Just trying to get a sense, on those areas. Yeah, no problem, Justin. On the CDMO lumpiness, there's definitely some capital equipment in there, but there's also consumables. So it's not—it's—you just can't look at the data and say, "Oh, it's all capital equipment." It's a combination of both, so I don't think it's favoring one versus the other. And then the CapEx comeback, I think that's more around dollars getting released. If you look at how last year played out on CapEx, we went back and looked at this. It was light in terms of CapEx for biotech, pharma, CDMOs in the first half of last year, and then there was a big step up in CapEx spend in the second half of the year. So you know, that's just a year ago. If you went back and looked at other years, you know, Q1 does tend to be on the lighter side, but it typically picks up as you go through Q2 and into the second half of the year. Thank you. Then just my follow-up, can you remind us what sort of the revenue opportunity is and the scale-up when you go from an early stage to, like, a late stage or commercial program, a la the nine programs you mentioned last year? And then, was there a book-to-bill for CGT that you could provide as well? ... Yeah, on the CGT, new modality space, it was a little bit above one, so, you know, a nice quarter for that portfolio. You know, it's hard to put a dollar amount on when you go, you know, from a phase I to II to III to commercial. But in general, the revenues tend to double, right? I think it's not a bad way to kinda look at it. But, you know, obviously, if you get into a more of a blockbuster drug and there's high demand, it could be much higher than a factor of two. It could be a factor of four between a phase III and commercial. But typically, the revenues would double. Appreciate it. Thank you. Thank you. The next question comes from Matt Stanton with Jefferies. Hey, thanks. Maybe sticking with the theme of new modalities, Tony, two-parter for you, I guess. First, 1Q is up mid-teens. I think you'd been looking for five to seven for the year. That's still the right way to think about it. Is there potentially an upside there on the heels of a strong start here in 1Q? And I guess, why can't that part keep up the pace we've seen, aside from maybe tougher comps in the back half of the year? And then just, you know, longer term, stepping back, any reason, you know, we can't see a return to kind of healthy double-digit growth for this part of the market, given the softer period more recently? And then you talked about adoption of OPUS within this category. Are there any other parts of the portfolio you think are relatively under indexed, to the new modalities? Thanks. Yeah. Thanks, Matt. That was a good few questions in that, but I'll decipher and walk you through it. I would say that, you know, good quarter, obviously in Q1, obviously double-digit growth, that's which is great. We've been pretty consistent, though, in saying that the new modality strength is coming from 2025 accounts. So it's not like the whole new modality space. The long tail in new modalities really hasn't caught up yet. So that, you know, biotech investment, that's starting to pick up in the first quarter for the industry should have an impact, but it could be nine-12 months before, you know, anyone really sees that flowing into the manufacturing side of the equation. So I think we have to be a little careful that we don't look at—we don't take Q1 and say: Oh, look, we're just gonna take Q1 and annualize it, because it really is driven by this sort of handful of accounts that we have that are scaling. So that's probably the important part. But I do think you're right. The tougher comps in the second half of the year will definitely slow down the growth. Now, last year, if you remember, you know, we had essentially the same revenue in 2023 as we had in 2022 in the new modality space. That was actually a great result, given how challenging, A, the space was, and B, the overall bioprocessing market. So I think we're in the right range in what we said in that, like, 5%-7% range, and I'd like to see another quarter or so before we say that that could be higher. Okay, thanks. And then, I guess, just on the second part, you know, longer term, is there anywhere of the portfolio on the new modalities? You know, you talked about the adoption with OPUS you really focused on. Are there other parts of the portfolio that are kind of under index, and you may look to run the same playbook over the coming years here, specifically within the new modalities? Yeah, if I looked at all the markets that we play in, new modalities is one where I think a vast majority of the Repligen technology portfolio plays out. I think we're at maybe 20% of revenue now in new modalities. And so when I look at our portfolio, you can clearly see OPUS, even our analytics business, when we bought the analytics business back in 2019 from C Technologies, it had no revenue in the new modality space, and I think around 20% of the revenue is now coming from new modalities. So that's a very nice positive uptick. Our whole fluid management portfolio, definitely opportunities, and we're getting traction there. And then you just have to look at anything from ATF to our flat sheet cassettes. Our whole portfolio of products really play nicely in the space. And then maybe I finish up, Matt, with a comment from Olivier Loeillot said, which was, you know, the RS 10 launch is absolutely geared towards this customer base. So if you think about where are we placing bets, we're definitely placing bets in this space, and some of the products that we're launching right now are totally geared towards this customer base, like the RS 10. Thanks. If I could just maybe squeeze one more in. Sounds like the U.S. was up, E.U. was down slightly tied to ligands. Would just be curious if you could talk a bit more about the trends within pharma between those two regions. Any differences between top 10 or 20 accounts and the small to mid-size customers between U.S. and Europe in the quarter? Thank you. Yeah, I would say that if we looked at the regions, the one region that was down in Q1 was APAC, right? With China. That was probably the one region where if you looked at, if it had a similar performance as what it had in Q4, we would be talking, you know, about a much higher book bill, right? But again, we're, I'm not trying to make any excuses. The problem is that every quarter, there's something that you weren't expecting that you have to deal with. And so look, if you look at us as a company over the last three or four quarters, we've been pretty consistent on the orders and pretty consistent on the revenue. What we need to see is an uptick, right? That's the way that we get to our sort of guide for the year. If you think about it, where if you took it ex proteins, I think we're up around 6% or so in Q1 versus where we were in... Actually, if you look at where we will be in the first half of this year, if you take the midpoint of, say, $305 million, between $300 million and $310 million, you go back to the last six months of last year, we're probably up 6% ex proteins on revenue. So to get to our midpoint of our guidance, we would need to be up 8% in the second half of the year versus the first half of the year. I don't think it's like a huge stretch, but we have a lot of execution that we have to do to get there. Super. Thank you. Thank you. This does conclude the question and answer session. I would now like to turn the conference back over to Tony Hunt for any closing comments. Great. Thanks, Keith, and, thanks, everybody, for joining. Obviously, a solid start to the year for us. Look forward to catching up with everybody at the end of July, beginning of August. So thanks again. Thank you. The conference has now concluded. Thank you for attending today's presentation. You may now disconnect.
