In Q2 2026, West Pharmaceutical Services (WST:US) reported a strong performance, with revenues exceeding expectations by over $35 million, driven primarily by the HBP components business. The company raised its full-year revenue growth guidance to 10%-11%, up 250 basis points from previous estimates, indicating robust demand and recovery post-cyber attack. Management highlighted significant growth drivers, including the continued rise in biologics and regulatory changes, positioning the company favorably for future expansion.

What topics did West Pharmaceutical Services, Inc. cover?

  • Revenue Growth Acceleration: West Pharmaceutical Services reported a Q2 revenue beat of over $35 million, with a 4.2% organic revenue increase. CFO Robert McMahon noted, "The momentum of the business continues to be strong," particularly in the HBP components business, which constitutes over 50% of total revenue.
  • Guidance Increase: The company raised its full-year revenue growth guidance to 10%-11%, a significant increase of 250 basis points. McMahon stated, "We feel very good about the continued momentum in that side of the business," reflecting confidence in future performance.
  • HBP Components Performance: The HBP components business showed strong growth, contributing over 8 points to the overall revenue guidance. McMahon mentioned, "The biggest contributor actually was non-GLP-1 HBP," indicating a shift in product demand.
  • Impact of Regulatory Changes: The regulatory framework around NX1 is expected to drive significant growth, contributing an incremental 200 basis points to overall company growth. McMahon noted, "We are still relatively early innings" in capitalizing on these opportunities.
  • GLP-1 Market Trends: Management remains optimistic about the GLP-1 business, which currently represents about 10% of revenues. McMahon stated, "We think there's still a long runway of that market in terms of just the amount of penetration to date," indicating potential for future growth.

What were West Pharmaceutical Services, Inc.'s September 10, 2026 results?

  • Q2 Revenue: $35 million beat (vs $11.8B est, +4.2% organic growth)
  • Full-Year Revenue Growth Guidance: 10% to 11% (up from previous guidance by 250 basis points)
  • HBP Components Growth Contribution: over 8 points (to overall revenue growth guidance)
  • NX1 Contribution to Growth: 200 basis points (incremental growth expected from regulatory changes)
  • GLP-1 Revenue Contribution: 10% (of total revenues, with potential for growth)
  • Asia Pacific Revenue Growth: over 25% (driven by GLP-1 demand)

West Pharmaceutical Services is positioned for strong growth, supported by robust demand in the HBP components business and favorable regulatory changes. The raised guidance and positive market trends suggest a solid investment opportunity, though investors should monitor competitive pressures in the GLP-1 market and the company's ability to maintain operational efficiency post-cyber attack.

Thanks, everyone, for coming to -- sticking around with us for day 3 of the Wells Fargo Healthcare Conference. We're really excited to have Bob McMahon, CFO of West Pharmaceutical Services with us here today. So thanks a lot for coming.

Evan Stampler

analyst
#2

Maybe as a place to start, new CEO, Michel, how do you think about leadership change is going to impact the business?

Robert McMahon

executive
#3

Yes. First of all, Evan, thanks for having us. It's great to be here. This was 1 year ago, this was the first conference that I had coming to West and it's been a great year, but I will tell you, there's still a lot more opportunities going forward, so I feel really good about the business. I would say Michel is joining the company at a really great time. As you guys know, we are the market leader in really serving a critical role within the pharmaceutical supply chain. And we've had some very nice momentum this year, and I'm sure we'll talk about that. And I think there's opportunities even to continue to expand that. And speaking with Michel, it's his week 2. And I think what's really great about him is he knows our markets extremely well. I mean he knows our customers and the fact he's already spent time with our customers. He's on a site visit going around looking at our sites and talking to our employees. And so I think he will continue to accelerate the work that's already being done. And actually, I think, elevate our conversations with customers, which I think will be good not only in terms of our current opportunities, but future opportunities. And so I expect not only a seamless transition, but an acceleration of the opportunities that we have in front of us.

Evan Stampler

analyst
#4

Great. Maybe just -- I mean you reported 2Q recently, a strong beat, $35 million, 4.2% organic revenue beat. What were the kind of -- what kind of exceeded your expectations? And what were the kind of the puts and takes in the quarter?

Robert McMahon

executive
#5

Yes. We were really pleased with Q2. The momentum of the business continues to be strong. The market's constructive demand continues to be there. It's very good and had -- I'm very pleased with Q2. As you mentioned, we beat by over $35 million. And really, the area that beat was our HBP components business, which is really over 50% of our business and our -- the business that we expect to continue to have the strongest lines going forward. And really both HBP, non-GLP-1 as well as GLP-1s performed very well. And this was on the back of recovering out of a cyber attack as well. And so we're very pleased with the team. The biggest contributor actually was non-GLP-1 HBP. And when you think about the growth drivers going forward, the continued rise at biologics, where we have greater than 90% participation rate the regulatory requirements around NX1 and just the overall kind of mix shift there. We feel very good about the continued momentum in that side of the business. We took our -- as a result of Q2 we actually took our guidance up by 250 basis points at the midpoint, and that's now 10% to 11% growth for the full year and very, very good.

Evan Stampler

analyst
#6

Yes, that's right. I mean that was where I was going to head next was on the guidance. And that's -- I mean, across the peer group, that's among the highest. What were the drivers of that increase? And then just kind of as we flow that through to margins, what kind of margin expansion are you now anticipating for within the guidance?

Robert McMahon

executive
#7

Yes. We started the year -- the strong growth is really driven by our HPP business, as I was mentioning before. Of that 10% to 11%, that's over 8 points of growth is HBP components growth. So very strong performance there, really driven by the underlying factors that I just kind of mentioned and we expect that to continue as we move forward. The rest of the performance was actually in our drug delivery device business, particularly in the first half of the year. But what's really nice is the HPP business also drives very nice margin expansion. And so with the addition of that, going from 7% to 9% to 10% to 11% for the full year, we are now forecasting greater than 200 basis points, almost 250 basis points of margin expansion growth for the year, that's 50 basis points higher than what we had seen in our previous guide. So very, very good start to the year. Not done yet, but feel good about the momentum in the business.

Evan Stampler

analyst
#8

That's great. I mean you mentioned a couple of times, HPC and the strength that you're seeing there. It was up, I think, high teens in the quarter, you mentioned. What were some of the underlying drivers of that performance? And were there any particular impacts within that segment from the cyber attack that you also mentioned. And should -- how should we think about any, I guess, follow through acceleration in that growth as you go through the rest of the year?

Robert McMahon

executive
#9

Yes. We're really pleased about the recovery that we had in Q2. And although there was some mix shift within -- the HPP growth that's really been driven by a couple of things. We talked a little bit about this continued mix shift really driven by NX1 or the regulatory requirements. That's been driving very strong performance, not only last year, but continues to do that this year. When we think about the number of programs. This is a regulatory framework that's come out of Europe and then we're actually starting to see some of those requirements and changes here in the U.S. as well. We had initially sized that at 6 billion components. We're about 1 billion into that right now. So still a long way to go, and that was just the European side. If you think about the U.S., that would obviously expand that 6 billion to even more, and we're actually seeing a potential acceleration in that. The number of programs that we have year-on-year was greater than 50% higher than it was this time last year. And so really feel good about that. The biologic approvals continues to be very strong, and that's where we also have a very good performance and participation. I mentioned our overall market share in the elastomer side is greater than 70%. But in biologics, it's greater than 90% as we measure it by participation. So as that goes we feel good. And then we've been ahead of our plan from a pricing perspective as well. And then obviously, GLP-1s, which I'm sure we'll talk about.

Evan Stampler

analyst
#10

I mean just you mentioned approvals, just came to my mind. I mean is that the best leading indicator to think about your business and potential growth? I mean, just because your attachment rate there seems so high I was just thinking that is that...

Robert McMahon

executive
#11

Yes, it's one of them. I would look at it in two elements. One is just the number of biologics that are in the pipeline, the clinical pipeline relative to small molecule the majority of biologics are used, injectable drugs. And so that as even a further leading indicator and then certainly more -- in a more near term would be a number of approvals. I would also say, as we think about kind of going forward, the opportunities that we have because of the way that our -- we were specked into these businesses. And so we have a very sticky business as some of those products are our molecules are going off a patent. When you talk about biosimilars, it's a real opportunity for us to actually continue to capture the volume there and potentially could even be greater because of lower pricing and greater market access. And so we also see that as a more of a longer-term growth opportunity for us as well. whereas -- and I think that's kind of a unique kind of opportunity that we're well positioned to take advantage of.

Evan Stampler

analyst
#12

So you mentioned Annex-1 a couple of times. What was the -- I mean if you can kind of contextualize the contribution from that and HCP components conversion in the quarter. What's driving this? And how should we think about that going forward? I mean I think maybe you are able to frame the actual number of projects in the quarter, so that would also be helpful.

Robert McMahon

executive
#13

Yes. So we've talked about NX1 contributing an incremental 200 basis points of growth for the total company. So if you think about kind of the component, the business, for HPP, it obviously has even a bigger impact for the HPP side. That continues to be very robust in terms of the number of projects that's approach a little over -- almost 800 projects now, which is 50% greater than where it was this year. That's a combination of projects that are currently being in production or development as well as production. And so you're starting to see those come through as higher value, moving up that value chain. And as I mentioned before, from a penetration standpoint, we're still relatively early innings, so to speak, of kind of that penetration. And then -- so we're very optimistic about the continued growth of NX1 opportunity for us going forward. As I mentioned, it's been primarily in Europe, but we are now seeing opportunities come in those projects in the U.S., which would expand that $6 billion market opportunity to even further. And so we see this as a multiyear tailwind for us. that we're uniquely positioned because we're on these drugs already. And so being able to take a standard product into an HBP, we are the supplier of choice from that standpoint, a partner of choice.

Evan Stampler

analyst
#14

Got you. Another thing that you mentioned a couple of times are GLP-1. It's very high level. Could you just talk about the trends you're seeing there? I know oral people were talking a lot about the orals and how that might be impacting the injectables. So any comments related to those?

Robert McMahon

executive
#15

Yes. We're still very optimistic about the GLP-1 business. It is about -- from an elastomer side, about 10% of our revenues. But we think there's still a long runway of that market in terms of just the amount of penetration to date. In the U.S. as well as the rest of the world. It's just getting started. Orals have been -- I know that's been a lot of talk, it's kind of playing out as we expected, which is actually bringing new patients into the into the market as opposed to cannibalizing the injectable side. The injectables still have benefits in terms of better efficacy, lower side effect profile. And if we think about kind of the additional opportunities going forward, there certainly are additional indications that are being investigated with the current drugs on market. There's a very robust pipeline of next-generation GLP-1s that will have even better side effect profiles, better weight loss or better efficacy. We have a very strong participation in those as well, so I think we're very well positioned to continue to drive that business going forward. And we have continued to increase our expectations for the GLP-1 contribution to growth throughout this year.

Evan Stampler

analyst
#16

Great. Sticking with GLP-1s, again, you mentioned generics. It sounds like some companies are not using West. You indicated -- I mean you indicated here as well as previously that you have strong participation in generics in India, Canada, China, Turkey and Brazil. So maybe just talk about just broadly, what's going on in the generic space with GLP-1.

Robert McMahon

executive
#17

Yes. I think if we think about kind of the GLP-1 space in general, I'll answer your question directly in just a second. There is still, as I mentioned before, a very long runway. And not only in the emerging markets through generics, but also in the developed markets with some of the things that I was talking about. And so we're very optimistic about the continued volume growth of this. What generics bring is a lower price point, and you're actually even seeing a lower price point in the U.S. and in certain markets in Europe as well. We actually see that as very positive for us because that actually increases access for patients more affordability. And so even in the U.S., not every -- not all employers cover GLP-1. So as more and more employers cover it, as the government covers it, there will be more patients on -- that'll have access to these drugs. And so we see that as very good in the developed markets. To your point specifically about generics, we have very good participation. You can see that in our numbers. In Q2, we had very strong growth in Asia Pacific over 25% growth on an organic basis. That was really driven by, in large part, some GLP-1 business in places like India and China. And I would also say, as we think about kind of the path for whether it be GLP-1s or biosimilars in general, the fastest path typically is to use the same delivery mechanism or packaging as the innovator drug is because you don't have to do as many studies, it lowers the regulatory and you had a potential risk and actually speed to market is critical there. And so what we see is if we're on the innovative drug or the branded drug, the biosimilar or generics will come to us and use the same elastomer equipment or same elastomers as the branded drug and use that in their process. And so there's a very small kind of drop out from that standpoint. And so we feel very good about our participation, to go back to your original question, in the generic marketplace for GLP-1s, I think more broadly for biosimilars.

Evan Stampler

analyst
#18

Maybe moving to the standard products. Slower growth there, but you were up 1% in the quarter. Maybe talk about what drove the performance there?

Robert McMahon

executive
#19

Yes. So standard products, roughly about 20% of our revenues. Think about that as the feeder pool into what we were just talking about as part of the HBP upgrade mix. So these are products that really are out in the marketplace today, but really have the opportunity, not all of them, but a lot of them have an opportunity to be upgraded to HBP over time. So we see this as -- so some of that is actually being impacted by -- as we are moving up the value chain, the growth rate in standard products kind of gets offset by that. But we think about this as kind of a really important pipeline for HPP going forward. And so it is a lower grower -- low and growing business. But we think about that as a way to upgrade stay with customers and then upgrade over time.

Evan Stampler

analyst
#20

Got you. I mean just thinking -- I mean it sounds like slower growth there is coupled with higher growth elsewhere is actually good in the initiation, right? Not just for your business, but also from a margin.

Robert McMahon

executive
#21

Yes, that's exactly right. One of the things that as you think about moving up that HVP value rate, the number of units actually doesn't change, but the value that we're providing to our customers and able to capture ourselves is very beneficial. And so to the extent that, that continues to be a source and the HPP business growing faster, that's actually a good thing for us. It says that strategy is working.

Evan Stampler

analyst
#22

PPD was also strong. I think you exited a business within that. What can we expect from that business going forward?

Robert McMahon

executive
#23

Yes. We had a really good first half of the year for our -- with our HBP drug delivery device business. This is where our SmartDose 3.5 is. We actually did better than we anticipated both in first quarter and second quarter, really helping support the transfer of that business to AbbVie that closed on July 1. But that business isn't solely SmartDose, so if we actually take the SmartDose 3.5 business out there, Q2, we actually grew double digits. This is our products like Crystal Zenith admin systems and our SmartDose 10, which we will continue to develop. And so we're optimistic about the continued growth. That's probably a slower grower, a slightly lower growth business today than what our HBP component growth is, call it, mid-single digits. But this year, if we think about the full year, it's double digit because of the strong first half.

Evan Stampler

analyst
#24

You did mention APAC. I think you said it grew 20%.

Robert McMahon

executive
#25

Yes. In excess of 25%.

Evan Stampler

analyst
#26

25% in the quarter, 27%. What drove that performance? And how should we think about that going forward?

Robert McMahon

executive
#27

Yes. If we think about our opportunities going forward, we've got a new leader in Asia now here for about the last 9 months. And I see there's a real opportunity to continue to capture growth. And today, a lot of that has been driven by GLP-1 that I mentioned before. But if we think about kind of the emerging dynamics that are happening in Asia, you're not only having an increasing number of aging individuals in Asia that want access to health care. You're also seeing -- which is -- which will drive volumes for us. But I think just as importantly and maybe more importantly, is the amount of innovation that's coming out for novel therapies and therapeutics out of Asia, particularly in China. It's just skyrocketed over the last, I would say, decade, and I would expect that to continue. And so those are not only in China for China, but also taking those molecules and bringing them into the U.S. and Europe as well. And so getting on those molecules early on is really what we're -- our strategy has been and will continue to be, and I think there's more growth in Europe -- excuse me, in Asia for that going forward to really get a good beat on what are the development activities that are going on there and then how do we actually help support them as they license those products back? Because typically what they'll do is, and you're seeing this many of the major pharma companies or major biotech companies are now licensing those products. Those are customers of ours already. And so if you can talk to them and say, hey, we've already got the best-in-class kind of containment systems, that's a much easier way to market in Europe and the U.S. And so we're optimistic about the growth in Asia, not only for this year, but for many years to come.

Evan Stampler

analyst
#28

Yes. No, based on what you were saying I was going to follow up with that. You hear a lot since you've seen this kind of explosion in China, people in the space across tools have been asking if it's coming from Asia, are they using cheaper copycat products. And typically, the answer is like, no, because they actually -- their exit strategy is -- that's what you're seeing as well. And so you're expecting at the trial. They know that they want to enter the U.S. market, and so...

Robert McMahon

executive
#29

Yes. And typically, what you'll start to see is depending on the company, they want to standardize on their certain containment platform. And so if there is a local platform that they want to bring into the U.S., they'll have to do additional studies or actually change it. And so to the extent that we can get there upfront and do that, it makes the diligence as well as that transition much easier for the multinational corporations that would want to bring those products into the U.S., not only from the standpoint of manufacturing, but even regulatory as well.

Evan Stampler

analyst
#30

Makes sense. Maybe moving to West Vantage. You invested heavily into this business a couple of years ago. How should investors think about the return on those investments? Do you expect them to drive an acceleration in growth in that business? And going forward, how much left? Or how are you thinking about further investments there?

Robert McMahon

executive
#31

Yes. So it's a good question. So our West Vantage business is a little less than 20%. I think it was 17% of the revenues in the quarter. It did have -- this was one area where we did have some deferred revenue associated with the cyber attack just because of the way the business model works. We'll catch that up in Q3 and Q4. But just for the benefit of everyone, we -- Q3 will be a trough in terms of performance because we exited a CGM contract that we've been talking about and are ramping up drug handling. And the reason I bring that up is because drug handling is where really our strategy is going forward. And so we're on track for $20 million. So the -- like CGM contract was about an $80 million annual contract, so about $40 million. It's already been built into our forecast. You'll see that come out in the second half of this year, roughly $20 million in Q3 and Q4 each. And then what we do have is a program and a strategy to actually add more value to the work that we're doing with customers, and we call it drug handling. But think about it as we make the auto injector and pens today, you assemble the product. And then somebody else actually puts the cartridge of drug product into that to make a finished good. Drug handling for us has been getting the cartridge ourselves, taking it because it's right off the manufacturing line, we do the QC to ensure that it's the right product, it's still within spec, actually put that in and make the finished good ourselves. So that is more value added. So what does that benefit our customers? It reduces a step in the manufacturing, somebody else that wouldn't be doing that, so it should reduce the time it would get take that product to market to finish because of the transit time. It also creates a more consistent regulatory or quality system, at least in that side. And so -- and we're taking some additional steps out of that manufacturing process. Now that's a higher profit. It's a higher risk for us because now we're handling drug product, but it's higher profit for us. And we're just getting into that business. Our strategy is to get more upstream into that business with West Vantage going forward. That $20 million that I mentioned before is on track. Most of that's in the back half of this year and about -- probably about $5 million of it was in the first half of the year. So $15 million in the second half of the year -- about $5 million in Q3 and then the rest in Q4. And so -- but that program is a $60-plus million program at full maturity, which is probably going to happen in 2028. So it will continue to grow in you could expect we're exiting at a $40 million kind of run rate, and that will continue to grow into '27. And we've got in our pipeline a number of other opportunities to expand. That's based in our Dublin facility, but we're looking for opportunities here in the U.S. to do that as well.

Evan Stampler

analyst
#32

Great. I mean sticking to West Vantage, margin performance. As you move towards these higher-value services, how should we think about like drug handling, you mentioned -- how should we think about the margin cadence or expectations for that going forward?

Robert McMahon

executive
#33

Yes. I'll start with Q2 was impacted because of the cyber. I mentioned it before, that's a highly levered business, so if you don't get the production out, you do have the cost and so forth, and as I mentioned, because it's a kind of a captive program, that revenue isn't lost, we'll capture it in Q3 and Q4. But it did impact our margin performance in the quarter. And I would -- so I would expect margins to improve in Q3 that's built into our guidance and then continue to improve going forward. The drug handling is -- should help accelerate our margin improvement in our West Vantage business over time as that ramps up, and our goal is to get it much closer to the overall company average over time. And we've invested heavily from a capital perspective in creating capacity for that business. And so I would expect the large amount of capital investments are largely behind us for the next several years there as we build out the programs to take advantage of that capacity that we've built. And where we would go invest, I would say, more disproportionately going forward from a capital standpoint is really behind our HPP business and particularly in the finishing areas where we would have a higher ROI, where from a capital perspective, moving into a 6% to 8% kind of range of CapEx spend for revenue. It's roughly $250 million this year and feel good about capital efficiency going forward. That's 1 of the areas that I'm really focused on making sure that we're investing in our highest return businesses and getting the returns up for the investments that we've already made.

Evan Stampler

analyst
#34

I mean you no mentioned is already moving upstream from where you are, and it sounds like West Vantage is part of that strategy. And I think knows a lot about moving upstream. So when you think about, I guess, organic investments and also M&A, what should investors expect on that front? And where are your capital allocation priorities? .

Robert McMahon

executive
#35

. Yes. One of the things I think is we're blessed with is a very strong balance sheet, but we generate a lot of cash as a company. And I think there's an opportunity to be better efficient or more efficient with that cash going forward. And so we spent time over the last year, driving that. And I think you can see some of that -- the results of some of that this year already in terms of how we're thinking about capital allocation. I would say first and foremost, it is around how do we continue to invest in the business to drive that organic growth. And as I mentioned before, disproportionately invest behind our HPP businesses to take advantage of the secular drivers that we were talking about earlier in the in the discussion as well as staying ahead of the curve, so to speak, in terms of taking advantage of that. So that's priority one. But I do think there is an opportunity to look beyond just our organic growth to more organic needs. And I would say stay tuned from that standpoint, but I think we have a right to play beyond kind of the critical component that we are in providing solutions to solve our customers' pain points across the supply chain. And so I do think that, that will be a more important thing over time. We obviously have to demonstrate the ability to do that. And then the last I would say is we continue to be committed to our dividend, but more probably just as importantly or more importantly, returning cash to shareholders is also important. And we -- we have an outstanding $1 billion share repurchase. We purchased about half of that $450 million in the first half of the year, and I would expect us to continue to be active in deploying capital.

Evan Stampler

analyst
#36

Great. That's all I got. It sounds like you covered a lot. Is there a big you want to...

Robert McMahon

executive
#37

No, I would just say -- and maybe I'll just -- I'll end where we started, which is I think West One of the reasons I came to West is really excited about the unique position that we play and the competitive -- the strong competitive position, the stickiness of our business and then the ongoing structural growth drivers that we have, I think...
