UBS MedTech, Tools and Genomics Summit 2023

Aug 16, 2023

John Sourbeer
Life Science Analyst, UBS

Thanks for welcome to the UBS 2023 Conference here. I'm John Sourbeer, UBS's Life Science Analyst. Happy to host the fireside today with West Pharmaceutical. Joining me is CEO and President, Eric Green, and VP of Investor Relations, Quintin Lai. Hi, thanks for attending here.

Eric Green
President and CEO, West Pharmaceutical Services

Yeah, John, thanks for having us. It's been a really good day here at UBS, so thank you.

John Sourbeer
Life Science Analyst, UBS

Great. You know, maybe start off here, you know, high-level question. I know you guys reported earnings a couple, couple weeks ago, but, you know, on the demand environment, you know, the company continues to see strong demand really across its proprietary product segment and the broader portfolio, despite macro headwinds, you know, seen by peers and others within, you know, biologics or larger pharma, you know, life science tools. I guess when you look at that demand, you know, how much of this is GLP-1s versus traditional biologics and ANDAs? Can you just talk about, you know, how sustainable is the current demand environment? Maybe pause there.

Eric Green
President and CEO, West Pharmaceutical Services

Yeah. Thanks, John. I think when we look at the growth of the business, it's really, you kind of break it down to two components. One, let's take COVID out of the picture. As you know, we had significant participation with during the pandemic. The core business itself, the base business, has been growing double digits since early 2019 consistently on a quarterly basis. It's really driven by a couple key areas. The number one is from the biologics. That continues to be the fastest area of growth for West, and our participation rate remains very high in that particular space. That also includes biosimilars, and we're also seeing good growth in out of our pharma and our generics business. In fact, generics has been growing quite faster than what we'd say about the long-term construct.

The business has been growing strong double digits for quite a while. However, when we think about high single-digit growth for West, we're really thinking about long-term growth algorithm of 7%-9%. The way to break that down is think about double-digit growth for biologics. Generics, we believe it's mid to high single digits for West. Pharma, which is an innovative molecule sector, is low to medium. In their contract manufacturing business, which is about 17% or 18% of our business, is growing. We believe long-term construct is mid to high single digits. When you roll that together, it gets you that 7%-9% long-term construct, which we have been exceeding over the last few years, which is positive.

John Sourbeer
Life Science Analyst, UBS

Great. You know, maybe just because you touched on it last, great question, maybe piece time to ask this. You know, the contract manufacturing, you did, I think, maybe two quarters ago, increased the contract there. Even with that being increased, you're still thinking 7%-9% long term is the sustainable growth for the business?

Eric Green
President and CEO, West Pharmaceutical Services

Yeah, for overall enterprise, just, you know, a few years ago, contract manufacturing was a larger portion of our overall enterprise, and that's come down to about 17%-18%. We do believe mid to high single-digit growth is what we'll see with contract manufacturing more long term. I realize this year we're good, solid double-digit growth that's due to layering capital we put in last year that is now up and running and commercialized today. The long-term, mid to high single, though, is our corridor with contract manufacturing.

John Sourbeer
Life Science Analyst, UBS

Great. You know, you typically don't talk about specific customer types, but there's lots of discussions about GLP-1. I'll try to try to ask him here another question on this, but, you know, any color, just how you see this evolving, you know, there's some oral GLP-1s that could potentially come to market, you know. How does this, you know, maybe impact the larger demand, you know, 10%-20% of these products shifting to oral, the right way to think about it? I guess that's when you look into your demand algorithm, how should we think about that?

Quintin Lai
VP of Investor Relations, West Pharmaceutical Services

I think that when you're, you're, you're right. I mean, we try to refrain from talking about any specific disease or, or drug category. You know, look, all things being equal, and they rarely are, drug companies, patients typically prefer oral. There is a reason why injectables are growing, because the effectiveness, the bioavailability, the amount of API required per dose to get that whatever effect they're looking for, trying to balance that versus potential side effects, all of those things come into play. I think that, you know, that all of those discussions have to come in, which is why we always refer those type of questions on the specific to the drug company, because really, they monitor and make those decisions.

What we do is we talk with all of our customers. We, you know, because of our position and our leadership, you know we share with them our expansion plans. Some things take time to build out capacity. On, on the flip side, what we ask of them is to get visibility on their near, mid, and long-term expectations. For, for customers that have larger launches or larger expectations, the touch points are more frequent, and, you know, we're always adding that as we're trying to do our capacity planning. What we've said and been fairly consistent here over the last couple of years is that we are adding HVP capacity. There has been a particular focus on plungers.

Just recently, you know, we brought online, one of our centers of excellence in the United States, our Kinston, North Carolina plant, NovaPure plunger capacity.

John Sourbeer
Life Science Analyst, UBS

Great. I want to dig in all those pieces, but maybe just one, one last one here to ask. I think broadly speaking, you know, you're in about 90% of the biologic filings. You know, any thoughts just on, on market share, you know, how that is maybe even GLP-1s or other products there on that piece?

Quintin Lai
VP of Investor Relations, West Pharmaceutical Services

Sure. The way we track it is our participation rate. We really focus on us and our partner, Daiichi, and how we're tracking with respect to NMEs, New Molecular Entity approvals. If you look at year to date, if you look at last year, if you look over the last five years, it's a really high participation rate. And, you know, we think that that is probably a good proxy for market participation.

John Sourbeer
Life Science Analyst, UBS

Great. Moving beyond the GLP-1s, and, you know, you guys just reported a nice 2Q earnings. You know, I guess just how should we think about the revenue cadence for the remainder year, you know, between the two quarters? I know you have some dynamics, capacity coming online, you have COVID rolling off. How just we think about that?

Eric Green
President and CEO, West Pharmaceutical Services

Well, I think take a look at. We believe the second half will be greater than the first half, and we have historically seen seasonality of our business, where Q2 tends to be the largest quarter, Q3 is less, and then it kind of reverts back to a higher level in Q4. That seasonality still exists as we look at 2023. However, we do have some, as Quintin indicated earlier, investments that we've been making. One in particular is in Kinston, North Carolina, with NovaPure plungers, that as where we sit today, as I'm speaking, we are ramping up on commercial manufacturing and supporting our customers. There is demand for the products.

That's why, obviously, we put the investments in, and we believe that plus, getting our lead times back in line to pre-pandemic levels, which we believe will take to the end of this year, will give us a stronger performance in Q3. Due to that, it's going to offset the seasonality. The way I would look at it is Q3 will be similar, plus or minus to Q2, and Q4 will be stronger. The second half will be stronger for us.

John Sourbeer
Life Science Analyst, UBS

Appreciate that. You know, with the capacity coming online and I guess specifically, Kinston, yep, any way to... I think you mentioned, so just to clarify, is that doubling your, your NovaPure capacity once that would be fully online, or how should we think about that?

Eric Green
President and CEO, West Pharmaceutical Services

That NovaPure in general, around our NovaPure plungers.

John Sourbeer
Life Science Analyst, UBS

Okay

Eric Green
President and CEO, West Pharmaceutical Services

At that site. It gives us significant expansion. The way that we made the investment is that we have the infrastructure expanded and modular approach. We have installed new equipment and technology to be able to produce the product with new team members on site. If demand continues to accelerate, we were able to install additional equipment without other infrastructure required. I think we've really purposely did a really good job on staging the investments and as we go forward, to stay ahead of the curve versus getting behind it, like we were in the last year or two. Really confident, we're positioned well now for NovaPure plungers.

John Sourbeer
Life Science Analyst, UBS

Great, you know, just maybe broader capacity, because you also have Jersey Shore, Pennsylvania, and Singapore, you mentioned. Just any additional color, just like, I guess, on the, the demand you're seeing?

Eric Green
President and CEO, West Pharmaceutical Services

Yeah

John Sourbeer
Life Science Analyst, UBS

A nd maybe how much is committed or any way to quantify that?

Eric Green
President and CEO, West Pharmaceutical Services

The way I would look at it, this year, we've committed to about $350 million of capital, which is, as you think about it, as percentage of sales, is higher than we've articulated in the past. We were looking at about 6%-7% of sales for capital for a business growing about 7%-9% organic top line. What we're seeing today with the 350, like we saw last year, is that about 70% of those investments is around growth. I think historically, at West, we were about 50/50, 50% on growth, about 50% on maintenance and IT. We're seeing heavier emphasis on growth, which is a good thing. It means that we are working with our customers, anticipating additional launches in the near to midterm time horizon. We're making investments.

It's not just in Kinston. These investments take one to 1.5 years from a modular point of view. We're making investments in our Waterford facility as we speak, Jersey Shore and Pennsylvania. Also, significant investments in Singapore, which is a great manufacturing platform for us for all of Asia, but other able to export it outside of Asia. It gives us the ability to support the growth that we're seeing High-Value Products. it disproportionately, investments are around plungers, not just NovaPure, but other types of formulations to be able to support growth that we're seeing in the biologics and other areas of the markets. We're, we're excited with these investments. There's multiple moving parts, but that's a good thing for us as we, we continue to look for growth in our organization.

Quintin Lai
VP of Investor Relations, West Pharmaceutical Services

You know, let me add a little bit to that. I mean, it kind of underscores the fact that we don't have really high concentration either to a single customer or a single drug class. The growth that we've been seeing since 2019 has been fairly widespread.

Y ou know, the capacity that we're adding, enables Westar quality, our SRU. It, it helps, our Envision capabilities. It, it works on at the floor tech level, as well as the high-profile NovaPure that we talk about. So, you know, it, it, you know, a lot of the tension gets put onto just Kinston, but, you know, we have a lot of efforts and a lot of projects going on throughout our network. Even in some of our standard areas, we have, projects going on. It, it, you know, we, we have a very robust, CapEx expansion right now going on.

John Sourbeer
Life Science Analyst, UBS

Thanks. you know, I guess just with that robust CapEx expansion, and you've talked about this, you know, plunger demand, but I guess even within your HVP capacity that you're bringing on or just broader current capacity, you know, any color on what products you're seeing the most demand there within your, your portfolio?

Eric Green
President and CEO, West Pharmaceutical Services

It is as Quintin mentioned, it's really across the whole portfolio, and it does show the robustness of how we're penetrating into the pharma, the generics, and also in the biologics. I 'd be remiss if I didn't say we are continuing to add capacity and contract manufacturing, but these are very long-term agreements. Our customers are also installing capital in these investments, so it's a joint long-term relationship. So it is across the spectrum, but I would argue that most of the investments are more the higher end of HVP, which is, which is positive because, as you know, we've been seeding the market. Where we win is in the pipelines, and, and we continue to see the market with the highest end of our High-Value Products.

We're seeing the high participation rate across the board, which is exciting, and we're preparing ourselves with customer conversations of additional launches that we're looking at, that are on us today and also into 2024.

John Sourbeer
Life Science Analyst, UBS

Thanks. you know, HVPs are roughly about 73% mixed today. I think you ended the year at 72% last year. Just any color on where you see the possibility for the penetration to go here, and then, you know, what would be the dynamics or maybe top line or bottom line impact from, from that?

Eric Green
President and CEO, West Pharmaceutical Services

We see HVP growth continue to be strong double digits. We see the key drivers of the growth really is in the biologics and biosimilar space. We're also seeing greater penetration in generics, and that is leveraging our AccelTRA and other parts of our portfolio in HVP. We're quite confident in our growth profile High-Value Products, which is actually quite exciting. We'll continue to invest in those areas, but it is kind of across multiple markets, multiple drug molecules, multiple customers, and multiple geographies. We're seeing the penetration continue to stay very high in that area.

John Sourbeer
Life Science Analyst, UBS

I guess just maybe back to another question, just on, on the seasonality in the second half. I believe that you mentioned that you're not seeing the normal plant shutdowns this year for different maintenance with the capacity coming online. Just any way to run through the, the color there on that?

Eric Green
President and CEO, West Pharmaceutical Services

I'll start with this. We are still shutting down plants in certain parts, like in Europe, to make sure that we are managing the maintenance, because that's so critical to keep our, the level of quality that we are producing each and every day and our customers are accustomed to. That is important for us to continue to do so. We do have larger vacation times, I guess, if you want to call it, in Europe this time of the year. We're not, we're not pulling back on our maintenance and shutdowns other than we have installed capacity that is ramping up to offset that this year, and particularly in Kinston and a couple other locations. That's how it's a puts and takes.

I think overall, it brings it to a higher level than we would've anticipated last year or the year before. Yes, definitely continue with the maintenance and, and the investments in those areas.

John Sourbeer
Life Science Analyst, UBS

Thanks. You know, GLPs get a lot of talk, but another area for driving that, that high single-digit growth you talked about have been biosimilars. Just any additional color on how you see, you know, biosimilars continuing to impact, you know, the market there, maybe near term or long term? Maybe pause there and then follow up on t his.

Eric Green
President and CEO, West Pharmaceutical Services

Yeah.

We, we still have a very strong participation rate in biosimilars like we do in biologics. It's, from a value proposition, our portfolio, our technology, jointly with Dyadic, really resonates well with our customers in both areas, because of the, the way it is able to support the, the molecule, right, as, as they launch. We're excited about the biosimilars as much as we are with the biologics. We're well-positioned. It's on a different product category for West. It's a similar value proposition, similar products that we are producing, such as NovaPure, off of our existing lines. We don't have to have any dedicated equipment for any particular customers or launches, so it, it fits really well with our business model, and we're excited with the growth opportunities in biosimilars as we are with, with, with the biologics.

John Sourbeer
Life Science Analyst, UBS

You kinda touched on there on the end, you know, if you're not the, say, the non-HVP product in, in the originator or, you know, transitioned, you know, usually, do you come in then on the biosimilar? Would it be an HVP product? Like, what level of HVP? Any color on that?

Eric Green
President and CEO, West Pharmaceutical Services

Yeah. You, you're right. When you think about NovaPure, the journey of NovaPure, we really launched that in, let's call it 2016 and beyond. Many of the molecules that may have improved in on the market and commercialized prior to that would not be leveraging NovaPure for the most part. As customers are looking to transition to a biosimilar, the discussions we have with our customers start with NovaPure.

A s in any other pipeline opportunity. There is that transition of a mixed effect that's gonna occur within our HVPs because of that effect as biosimilars are being approved, we're seeing higher leverage and usage of our NovaPure portfolio.

John Sourbeer
Life Science Analyst, UBS

I guess just, just on pricing, I think you're targeting still this year, 5%-6% pricing increases.

Eric Green
President and CEO, West Pharmaceutical Services

Yeah.

John Sourbeer
Life Science Analyst, UBS

Just any thoughts, you know, long term on how the sustainability of the pricing you've been able to capture here?

Quintin Lai
VP of Investor Relations, West Pharmaceutical Services

Yeah. So, let's kinda start with, historically, a few years ago, the company would get about 1%-2% price per year, often at the lower end of that range. We have talked about looking at price more strategically, and we have, you know, brought in teams to look at that. Over the last few years, I believe we have been more strategic on pricing to be a little bit better than what that historical range has been. You couple it with the inflation pressures that have occurred for not just us, but the whole economy over the last 2 years.

You know, we've been able to then take that and be able to use that, that, that structure that we have with pricing to be able to help offset some of the inflationary costs that are coming in. This year, what we had said is that it is gonna be 5%-6%. That is markedly higher than where it has been, but we're also experiencing inflationary issues, some material, some supplies, some utilities, but in particular, labor, because of the, you know, labor demands here over the last, you know, two years. You know, that has driven us to where we are.

We haven't given any forward guidance on where it could go, but again, you know, I, I'll just leave it as that, that, you know, we continue to believe that we can continue to be more strategic, certainly than the historical 1%-2%.

John Sourbeer
Life Science Analyst, UBS

You know, Eric, you touched on this a little bit in the beginning, just in the overview of the demand market, but, you know, you recently increased the contract manufacturing piece to that mid-single digit, high single-digit growth there. Just any additional color on, you know, what drove the increase in your outlook and the expectation for that segment of your business?

Eric Green
President and CEO, West Pharmaceutical Services

It's, it's these long-term agreements that we're signing and, and starting to invest in. We, we do have visibility. That's one part of the business where the installed equipment, new facilities, are really dedicated to a particular product and a customer. These are very long-term, i.e., five, seven -plus year agreements. With, with that being layered in and knowing that we are- we'll be turning those on and the, the requirements get to close to 100% utilization as soon as possible, gives us pretty good confidence of moving that up between, you know, mid to high single digits, more longer, longer term. The particular area around autoinjectors is probably the biggest driver.

When you think about in the injectable medicine space, we participate the number of autoinjectors, but that's probably the biggest area of growth we're seeing right now in CM.

John Sourbeer
Life Science Analyst, UBS

You know, maybe moving to a little bit below the line and some of the impact on, on the HVPs there. Can you just remind us the impact on HVPs on margin versus maybe non-margin mix? Any way just to quantify that, to say every 100 basis points increase, how that impacts?

Eric Green
President and CEO, West Pharmaceutical Services

Yeah

Quintin Lai
VP of Investor Relations, West Pharmaceutical Services

I'm sorry.

John Sourbeer
Life Science Analyst, UBS

The HVPs on margins. Just how should we say, like, every 100 basis points of penetration increase there? Maybe the thoughts on, on that?

Quintin Lai
VP of Investor Relations, West Pharmaceutical Services

Yeah. Again, so, so, a couple things there. I think that, that when, you know, you have a top line, 7%-9% construct, organic sales consolidated, that, that presumes that HVPs are growing north of that and that standard products are growing less than that. Let's get away from % of sales. Let's just look at the, the, the drivers plus or minus to that. When HVPs are growing in the double digits, given their margin profile, yeah, the construct would yield about a 70%-80%, 80 basis points per year of gross margin improvement. With other operational efficiencies, plus a little leverage on SG&A per year, then that gets us to the 100 basis points plus per year construct. Nothing has changed. You're absolutely correct.

HVPs are gonna be the driver of top line, as well as gross and operating margin expansion.

John Sourbeer
Life Science Analyst, UBS

Thanks. You know, maybe just now switching to some of the, the more macro near term.

You know, any updates on Pfizer, you know, the situation in Rocky Mount, you know, with the recent storms there? You know, luckily, no one was hurt, you know, any just thoughts on the broader impact and any updates since the quarter there on that?

Eric Green
President and CEO, West Pharmaceutical Services

Yeah, no, it's just devastating to, to see what, what impact it had at that site. We reached out immediately afterwards. As you know, we have our own facility in Kinston, North Carolina. It's about 50 miles or so from their location. Our teams know each other very well, and we reached out and said, you know, to determine what we can do to support them in any given way. The whole supply chain is ready to react to build support in a meaningful way to make sure that there isn't a disruption for them. Yeah, it's more we'll see more as we go down the road, and we're ready to respond.

John Sourbeer
Life Science Analyst, UBS

T hanks. You know, any color just on, you know, we've seen some destocking from those life science tools companies that are facing you with bio, biologic customers. Just how are you seeing any impact from that?

Eric Green
President and CEO, West Pharmaceutical Services

Yeah.

What we're seeing in the working capital or working management, capital management, we think about, obviously, COVID is an area where we're seeing destocking. You know, last year, we did about $388 million of COVID-related materials, and this year it's gonna be we're forecasting about $60 million. There's an effect there. We are seeing some destocking in areas around the disposable medical devices , or call it, standard products. For us, it's, it's another area we, we tend to see a little bit of this happening, but these, these amounts are not material to us. We're able to manage through that, work with our customers, keep our operating facilities in check. If, if it will have an impact on site, we do work with our customers.

For the most part, when you think about during the COVID time period, we were getting behind in our lead times. Many of our customers' safety stock levels did not get escalated or get larger than they anticipated during the, during the pandemic. We're actually in a good place right now, where our lead times did get a little bit large. We, we brought them in. We're working down the, the, the need for additional materials with our customers. We-- right now, where we stand, what we see is not a lot of destocking with our products.

John Sourbeer
Life Science Analyst, UBS

Thanks. I guess while we're on the, the near term and the macro, you know, I think China is a small portion of your revenues, but, can you remind us what the exposure is there and just any color on the outlook for the China market?

Eric Green
President and CEO, West Pharmaceutical Services

I'll cover that. Yeah. I think it's a small percentage of our business. We do have two manufacturing plants in Qingpu, just outside of Shanghai, that really supports the local market with certain product portfolios that's focused on that area. We actually are seeing good growth outside of COVID. That's another part of the world where we're seeing a decline in COVID. Net we're seeing relatively neutral. We're not seeing a reduction. Our reliance on raw materials coming out of there is less. A lot of our sourcing of our materials are really co-located with our manufacturing plants and on the, on the continents, so we have less risk in those areas. It's, it's a small piece of our business, so it's really not material.

We haven't really called it out, and frankly, we're not seeing a, a big change on the demand profile in China for us today.

Quintin Lai
VP of Investor Relations, West Pharmaceutical Services

Yeah. John, as a reminder, I mean, our, our exposure in China, as well as the rest of the world, is mostly on commercial volumes. We, we do sell some to customers that are doing preclinical and clinical trials, but that volume is small relative to the rest of the business, and we don't have really any sales to, to speak of at the discovery level.

You know, you know, to compare and contrast with other life science tools companies.

John Sourbeer
Life Science Analyst, UBS

That's great, you know, lead to the next question.

You know, West is very highly levered to those commercial revenues. You know, any just impact you've seen from, you know, say, funding or even slowing of R&D from pharma customers, you know, has that impacted the business at all?

Eric Green
President and CEO, West Pharmaceutical Services

No. No, it hasn't. As we mentioned earlier, our, our success really is in the pipeline, so you're right, it's an important area to be focused on. But the, from a revenue and profit perspective, it's very small, minimal impact. These volumes are very limited. We are seeding the markets with Ready Pack and other materials, but it's really meaningful when it gets into commercial stages. Today, we do believe the engine of innovation continues to thrive, and we'll continue to support it, you know, long, short term and midterm.

John Sourbeer
Life Science Analyst, UBS

Might as well ask one on COVID while we're here. Just, you know, you've cut COVID guidance this year.

You know, when you look at now two quarters in, any way to think about the endemic run rate from here and just where COVID, you know, you can see the tracking from, from here?

Quintin Lai
VP of Investor Relations, West Pharmaceutical Services

Yeah, I mean, look, I, I think we, along with all of society, are hoping that we are getting to a, the, the, this lower phase and, and, and, and kind of situation with COVID. For the back half of the year, the expectations are, you know, really small in terms of our COVID sales, and as Eric says, you know, we definitely have seen destocking in that area. In the event that the pandemic rears up again, and if there is a need for vaccines and treatments, we'll be ready, you know, and that is our commitment. We'll, we'll, we'll be there, but right now, nothing to add.

John Sourbeer
Life Science Analyst, UBS

Thanks. You know, I wanted to ask one on the, the Corning collaboration and the, the West Ready Pack, the Corning, Corning Valor. Just any color on demand there and just how this could potentially play out and increase demand on HVPs or, or NovaPure?

Eric Green
President and CEO, West Pharmaceutical Services

Yeah, it's an exciting area of investment that we're making, working with Corning. You know, the concept there is that we do believe that there's a drive towards integrated systems, and the elastomer component is a critical element of any type of system, whether you're talking about a cartridge or a prefilled syringe. Working with Corning gives us the ability to bring the glass element, which we currently do not have. So we're excited. We've, we've had a couple launches around the vial configuration, and we'll continue to work all the way up to a fully characterized prefilled syringe.

I n the near future. Our focus is really, again, to seed the market and then bring the demand in through new approvals. But we're in a very unique position with that relationship to ultimately get to what we believe, a 1 Drug Master File approval approach with our customers, which is resonating very well in the market today. The question is: How fast can we go? We're deliberately, you know, we're working swiftly with our internally, both at Corning and at West, but also with our customers. We'll more to come, but it's very early at this point in time.

John Sourbeer
Life Science Analyst, UBS

I guess just broader on that and moving to that, you know, the one product approval, just any changes in the competitive dynamics in the broader industry that you've noticed now that we're exiting the COVID pandemic?

Eric Green
President and CEO, West Pharmaceutical Services

Look, we have really, formidable, you know, competitors in the marketplace, really good companies, well-run. We don't see a change in the dynamics of market share. In particular, we do, we do monitor very closely what we call participation rate of new, new, approvals, and we continue to have very high acceptance of biologics. Obviously, other NMEs in the small molecule area, and also seeing a little tick up in the ANDAs or the generics area. From our lens and our position, we don't see any, any major shift at this point, particularly on the elastomers of our business.

John Sourbeer
Life Science Analyst, UBS

The question we have here and from the audience, y our lead times are returning back to those normalized level, do you speak into any of the visibility into customer inventories or other metrics that might insulate West from lower ordering patterns, which have come up in other parts of the pharma manufacturing chain?

Eric Green
President and CEO, West Pharmaceutical Services

Yeah, one encouraging area is that because we're bringing the lead times down, customers are getting more confident in shorter lead times. Therefore, we're having more frequent, more near-term orders versus very elongated, one, two years out type of approach. That's where we wanted to get to, it allows us to be more flexible with our operations. It allows us to be more responsive to our customers' needs. It allows them, our customers, to not have to build significant levels of safety stock. We're in a much better position today, and the visibility remains, continues to remain very high.

We do interact with our customers frequently on not just current drug molecules in the marketplace, but also, planning for future launches or, near and midterm, because sometimes we will have to make investments in advance to make sure that we can handle the volumes that will be asked upon us. The, the lens is very good for us, and, we continue to build off of that. I think that's been one of the biggest changes we made in this organization over the last five or six years, which is really paying off today.

I guess, have you, have you quantified what lead times are now, let's say, where they were height of the pandemic, 2021, how they've come down from a maybe months out in ordering?

Quintin Lai
VP of Investor Relations, West Pharmaceutical Services

It varies by SKUs, but we had some certain HVP categories that the lead times exceeded 40 weeks. You know, what we like-- we, we would rather see in some of those cases to be between 10-14 weeks, maybe sometimes between eight to 10. Our expectation now is that, as we've been bringing on HVP processing capacity, and that began last year and into this year, as we've brought in now more plunger capacity and NovaPure capacity, that by the end of the year, m- the, the majority of our, our portfolio will be getting back to more normalized lead times.

Thanks. You know, we touched on lots of different parts of the business. One we haven't talked on is the generics segment. Just any color there in the year-to-date performance and outlook in the second half?

Quintin Lai
VP of Investor Relations, West Pharmaceutical Services

Yeah. Yeah, I think generics has been really. If you look at it, excluding COVID-19 impact, it has been really strong double-digit growth in generics. A part of that has been a benefit from the fact that we've been able to work some of the lead times down and bring up the safety stocks of certain, these long lead time items that were, and then so now, you know, stocks are being replenished.

The rest of the underlying growth continues to be good because the volumes have been good, the number of ANDAs and our participation rate have been good, and the conversion of some of these customers moving to like a Westar RU format, a ready-to-use format, have been good, and that, those, those have all been drivers. It's kind of a combination of all three.

Great. you know, we're reaching about time here. Just last question, maybe just more Quintin, just follow up on, on the margin piece. Can you just run through on just, I guess, we talked to top-line cadence, second half, just on how margins should track? You know, should they track in line with revenues, with the dynamics of capacity coming online and, and thoughts there on that?

Quintin Lai
VP of Investor Relations, West Pharmaceutical Services

Yeah. If you look at it from a typical seasonality, if you look at a typical West year, which has been a long time since we had a typical West year with COVID going up, coming down, all that. The second quarter typically is our largest sales quarter. It would typically is our best gross margin quarter because it's also we have great utilization, more uptime, good absorption. The lowest quarter typically is Q3 because of the summer shutdown, especially in Europe, Q4 is the second lowest. Those dynamics of the seasonality will continue, the drop in gross margins will not be as dramatic as in prior years because we are bringing on capacity for HVP.

The implications in our guidance is that capacity is gonna come on at nice incremental margins, but not the full contribution margin, given the fact that it's a new facility and you always have start-up costs with the, the, the new facility. That is the net-net of why sales will be plus or minus, where, you know, Q2 are better than Q4, but margins will be just a tad less than what we saw in Q2.
