Good morning, and thank you for joining us. This morning, we announced another strong year of performance, extending our track record of year-over-year revenue growth to 20 consecutive years. In 2025, the total company revenue increased 5.7% to $1.164 billion or 5.2% growth on a constant currency basis versus 2024. Adjusted EBITDA increased 8.2% or 7.8% on a constant currency basis with margins expanding to 51%, an increase of nearly 120 basis points. We also delivered adjusted free cash flow of over $200 million in 2025. Our results demonstrate strong execution, growing demand for our mission critical services, and disciplined financial management. The team's performance in 2025 positions this wealth for sustained growth ahead. We also had several notable achievements during the year. Our customer satisfaction exceeded 80%, underscoring our commitment to delivering excellent service. We advanced our portfolio across several key areas, including our commercial initiatives continue to build momentum with revenue from XBU customers expanding 9% year-over-year. Sterigenics delivered approximately 8% constant currency revenue growth versus 2024, driven by improved volume and mix. Significant progress was also made on the EO Facility Enhancement Program as well as the construction of the new x-ray facility which is planned to open in 2026. Norion delivered a strong year achieving approximately nine percent constant currency revenue growth. Also in the fourth quarter the team signed a cobalt development agreement with Westinghouse and PSE&G and they secured a 25-year Class 1B license renewal for our Ottawa facility, which is the longest ever issued by the Canadian Nuclear Safety Commission. Nelson Labs delivered core lab testing growth during the year. They expanded their margins by 312 basis points and made progress on a clean investment. On the capital markets front, we reduced borrowing costs by 75 basis points on our $1.4 billion term loan and paid down $86 million of debt, resulting in $13 million of the annual interest savings. We also upsized and extended our revolver, increasing liquidity by $175 million. Sotera Health's public flow increased to 80% of outstanding shares during 2025. We continue to strengthen our corporate governance with the appointment of a lead independent director also as you may have seen we welcomed richard kyle to the board earlier this month richard's leadership experience as a public company ceo and his extensive experience in operations and governance along with a strong financial acumen will serve as tremendous assets as we continue to grow finally we remain actually engaged with our shareholders on many corporate responsibility initiatives. 2025 was a strong first step in executing the 2025 to 2027 long-range plan we presented on our November 2024 investor day, and we expect this year to represent another meaningful year of progress towards those goals. Earlier today, we issued our 2026 outlook. For the full year, we expect total revenue to increase to a range of $1.233 billion to $1.251 billion, representing constant currency growth of 5% to 6.5% versus 2025. Adjusted EBITDA to grow to a range of $632 to $641 million, or 5.5% to 7% constant currency growth. Before I hand it over to John, I'd like to highlight a management transition. As you may have seen in our press release this morning, effective April 1st of this year, Senior Vice President General Counsel Alex Dmitry transitioned to an outside advisor to the company. I would like to thank Alex for his leadership and service the past three years, and we are grateful that he will continue to support the company going forward as an advisor. We are excited to announce that Eric Ostrowski, who has served for the last two years as a Vice President, Deputy General Counsel, and Corporate Secretary under Alex's leadership will be promoted to the Senior Vice President and General Counsel for Sotera Health after demonstrating strong leadership, sound judgment, and a deep understanding of our business. Erica is well-positioned to continue success in her new role. Now, John will take us to our fourth quarter in full year 2025 financials and our 2026 outlook in more than.
Thank you, Michael. I'll begin with our consolidated fourth quarter and full year 2025 results and close with additional detail on our 2026 outlook. For the quarter, total company revenues increased 4.6% to $303 million, or 2.5% on a constant currency basis, versus Q4 2024. The year-over-year comparison reflects the expected impact of Cobalt-60 harvest timing at Nordia. Adjusted EBITDA grew 2.7% to $157 million, or 0.5% on a constant currency basis, while adjusted EBITDA margins were 51.8% for the quarter. Interest expense was $35 million in the quarter, a $6 million improvement versus Q4 2024. Net income was $35 million, or 12 cents per diluted share. Adjusted ETS increased to $0.26, up $0.05 from the prior year, driven by a lower tax rate, as well as strong operating performance and lower interest expense, partially offset by higher depreciation. Now let's take a closer look at our segment performances for the fourth quarter as compared to the same period last year. Sterigenics' revenue improved 10.6% to $198 million, or 8% on a constant currency basis. Growth was driven by 4.3% favorable pricing, 3.7% volume and mix, as well as a 2.6% foreign currency benefit. Segment income increased 10.4% to $110 million, or 7.8% on a constant currency basis, reflecting favorable pricing, volume and mix, and foreign currency partially offset by inflation. As expected, Nordian's revenue decreased 12.3% to $50 million as the timing of cobalt-60 harvest schedules drove unfavorable vine and mix of 15%, which was partially offset by 2.4% favorable pricing. Nordian segment income decreased by 18.9% to $29 million. Segment income margins decreased 466 basis points to 57.5%, primarily driven by the lower volumes, and unfavorable product mix. Nelson Labs revenue increased 2.3% to $55 million, which was nearly flat on a constant currency basis. Favorable pricing of 3.2%, foreign exchange of 2.5%, and core lab testing growth were partially offset by lower expert advisory services revenue. Segment income rose 1.9% to $18 million, a decline of 1.2% on a constant currency basis. Growth was driven by favorable pricing, growth in core lab testing in foreign currency, partially offset by lower expert advisory services revenue and higher costs. Now, let's turn to the full-year 2025 results as compared to the prior year on a consolidated basis. We delivered revenue growth of 5.7% to $1.164 billion, or 5.2% on a constant currency basis. Adjusted EBITDA improved 8.2% to $593.8 million, or 7.8% on a constant currency basis, resulting in adjusted EBITDA margins of 51% and improvement of 118 basis points. Interest expense improved $9 million to $156 million, driven by lower interest rates, the favorably pricing of our term loan, and $86 million of debt paydown. Reported net income for 2025 was $78 million, or $0.27, per diluted shares. adjusted EPS for the year was 86 cents per weighted average diluted share an increase of 16 cents versus 2024 driven by operational growth a lower tax rate and improved interest expense partially offset by higher depreciation I will now turn to the balance sheet cash generation and capital deployment for the full year 2025 adjusted free cash flow was 210 million dollars putting us well on track to achieve the 2025 through 2027 cumulative goal of $500 to $600 million we set at our November 2024 Investor Day. Capital expenditures totaled $138 million in 2025. The company continues to maintain a strong liquidity position. As of December 31, 2025, we had approximately $940 million of available liquidity, including $345 million of unrestricted cash and nearly $600 million of capacity under our revolving credit facility. Net leverage improved to 3.2 times at year end from 3.7 times in 2024 as we continued progressing toward our two to three times long-term target. Turning to our 2026 outlook, for the full year, we expect total company revenue to grow to a range of $1.233 to $1.251 billion, representing 5% to 6.5% constant currency growth and an estimated 100 basis point foreign currency benefit as compared to 2025. We expect adjusted EBITDA to improve to a range of $632 to $641 million, representing 5.5% to 7% constant currency growth and an estimated 100 basis point impact from foreign currency. The foreign exchange benefit is expected to be weighted toward the first half of 2026 with the largest impact expected in the first quarter. Total company pricing is expected to be approximately the midpoint of our 3% to 4% long-term range. For 2026, we expect Sterigenics to deliver mid- to high-single-digits constant currency revenue growth year-over-year, with the first quarter anticipated to grow in the mid-single-digits range. We expect the first quarter revenue to be the lightest of the year. We expect Nordian to grow constant currency revenue in the low- to mid-single digits in 2026. Nordian's first-half 2026 revenue is expected to represent approximately 40% to 45% of full-year revenue, with Q2 2026 revenue expected to be heavier than Q1 2026. For Nelson Labs, we expect full-year 2026 constant currency revenue growth to be in the low single digits, with Q1 growth expected to decline low to mid single digits versus Q1 2025. Additionally, Q1 2026 revenue is expected to be the lightest quarter of the year. For 2026, we expect interest expense between $135 to $145 million based on the current forward rate curve. We are projecting an effective tax rate applicable to adjusted net income in the range of 27 to 29%. Adjusted EPS is expected to be in the range of $0.93 to $1.01, driven by operational growth as well as improved interest expense. We expect depreciation to increase in 2026, consistent with the step-up we experienced in 2025. We expect a fully diluted share count in the range of $289 million to $291 million shares on a weighted average basis. Capital expenditures are expected to be in the range of $175 million to $225 million in 2026. We expect to make continued progress in reducing our net leverage ratio again in 2026. Finally, as usual, our guidance does not assume any M&AM activity. I will now turn the call back over to Michael for closing remarks. Thank you, John.
As we move into 2026, we are encouraged by our momentum, strength, and balance sheet, and we are confident in our ability to drive long-term growth, strong cash flow, and shareholder value. We are on track to meet the commitments we made in our November 2024 investor day, and are confident in our team's ability to execute and deliver for our customers and investors. We remain focused on executing on the priorities we've laid out previously, which are excellence in serving our customers with end-to-end solutions, winning growth markets, driving operational excellence to enhance free cash flow, and disciplined capital deployment. At this point, Operator, let's open the call up for questions and answers.
Operator
Thank you. We will now begin the question and answer session. To ask a question, you may press star, then one-one on your touchtone phone. If you are using a speakerphone, please pick up a handset before pressing any keys. To withdraw your question from the queue, please press star, then 1-1 again. At this time, we will pause momentarily to assemble our roster. All right, one moment for our first question. Our first question comes from Sean Dodge with BMO Capital Markets. Your line is open.
Yeah, thanks. Good morning. Maybe just starting on the guidance and the EBITDA margins, at the midpoint implies about 20 basis points of expansion. that's on top of a pretty significant improvement you drove in in 2025 what you're targeting this year is that all just operating leverage or is there any other dynamics kind of happening there worth calling out are you taking costs out adding costs in anywhere are there any unusual mix impacts or anything else like that i guess it looks like nelson will be a little bit of a kind of a slower grower so you get a little bit of a mixed benefit from that but but anything else um worth highlighting hey sean thanks for the question no you're spot on with uh the midpoint of the guide and what it implies and no it's nothing abnormal uh going on just normal operating leverage and running the running the business okay uh great and then on sterigenics you mentioned recently you had one or at least one client that had been uh in sourcing sterilization that's now chosen to outsource to you all. Is there any more background you can share on their decision? Was that all because of NSHAP or were there some other factors driving that decision to finally outsource? And then maybe anything on like the magnitude timing of that shift? And I know you're not building these into numbers, but are we starting to see kind of ice break now and the backdrop being set for more of these decisions to happen?
Yeah, Sean, this is Michael. Good morning. I would say we don't see, I think it works for ice breaking, or we're not seeing significant shifts in that arena at this point in time. You know, the compliance period's out for two more years. The one customer you're referencing that we've talked about in the past, we'll start to bring some volume in late this year, and it'll roll in through 27 and 28. You know, there's lots of factors that go into the decisions. You know, that's ultimately the customer's choice. I'm sure the requirements of the new regulations was a factor. I can't speak on behalf of the customer and all the details, and also I've got to respect some confidentiality we have in place with them. But overall, you know, we're progressing, as we told you previously, that that customer would be transitioning over to us with their sterilization volume. Okay, great.
Operator
Thanks, Sean. One moment for our next question. Our next question comes from Patrick Donnelly with Citi. Your line is open.
Hey, guys. Thank you for taking the questions. Michael, maybe one for you on Sterigenics. Can you just talk about how you're thinking about 26, both on the volume and pricing side? We'd love just a little color on areas like bioprocessing, medtech. How are you thinking about just those categories improving throughout 26 and what you're seeing on the demand front?
Yeah, thanks, Patrick. I would say, you know, we've gotten out a long-range guide for the company at 3% to 4% price. Sterigenics, you know, came in in 25 on the high end of that range, which is what we call for. We'd expect the same thing to happen in 2026. Bioprocessing, you know, we have a very small base, but we had significant growth that we experienced last year. We'd expect that to continue as we move into 2026. And MedTech volumes, you know, we saw growth and volume in mixes the year progressed, and we expect that to continue into 2026 as well. And we're seeing across multiple categories, as we referenced in our last call, and I'd say we're seeing the consistency there as well.
And the other thing I'd call out, Patrick, as I think about it, is the commercial segment has been a little bit more challenging, some of the volumes there. We've wrapped up 25, looking into 26. But overall, the core volumes, which are really the foundation for the business, is MedTech, and those are in a pretty good spot.
Okay. That's helpful. And then I'd be just Nelson Lab. Then you guys have the EAS headwinds. Those are going to ease, sounds like one, two, maybe down a little bit. How do you think about the progression through the year there and as that headline eases? And then maybe for John on the Nelson margins, I know that's a big driver for margin expansion. Is 26 getting back to that low to mid-30%? Let's just remove some color there. Thank you, guys.
Yeah, I'll start with the second part of your question there, Patrick, on the margin side. We see Nelson solidly staying in the low to mid-30s again this year. Q1 could you know is being the lightest quarter I expect on the lower lower side of the margin rate you know and then the first part of your question could you repeat again was about Nelson progression throughout the year on the revenue side yes yeah just with the EAS headwinds how you think about it yeah I would say that the biggest head when we have the expert advisory comp actually have a little bit trailing into Q1 comp challenge, so we should improve from here, and this should be the last quarter where we face that kind of headwind. It's a lower headwind than it's been, but it's still meaningful to the quarter.
And remember, first quarters typically are softest quarter in that business. Every year, it's like that, so margins and volumes will be softer in the first quarter.
Operator
One moment for our next question.
Our next question comes from Luke Sergot with Barclays your line is open this is Salem on for Luke thanks for taking our question maybe just piggybacking off of Patrick's question on 1q guide sterigenics ramping a little bit throughout the year I think you talked a little bit about how how volumes are kind of accelerating out of the year but if you could just talk about any dynamics at play there with the slightly slower start to the year for Sterigenics. Thanks.
Yeah, thanks, Sam. You know, Sterigenics, like Nelson, typically the first quarter is the softest quarter. We also, kind of where we sit today, we're seeing a soft start to the year. Some of that's shutdown-related, some, but also there is some weather impact that we felt as well. But we're guiding towards mid-single digits as we kind of look at the first quarter for Sterigenics.
Got it. That's helpful. And then if you could talk a little bit about the x-ray facility um and when exactly it opens in 26 maybe uh any tailwinds associated with the facility opening um and maybe just talk about a little bit uh on the strategy behind opening the x-ray facility and how bringing in that capability helps to serve customers and create new opportunities yeah sam we you know we're we're full supplier across sterilization all the modalities you know we made the strategic decision uh over three years ago when you know we go through a three-year strat plan every year with our board and in that in the process of that you know mike
the team laid out a strategic plan that builds more x-ray capability beyond the capability we already have today we expect that to open up in the second half of this year we're in a qualification with with our customers you know just like any other facility that'll have a ramp period over time. There'll be a little impact in 2026, and then we'll start to see that, you know, accelerate in 27 and 28 and beyond. But this was a long-term strategic investment. We've got to co-locate with the gamma facilities. We're working with some customers on qualifications now. But again, it's more part of our longer strategic plan to make sure we have full service offering across all modalities.
Operator
Got it. Appreciate it, Michael. Thank you. One moment for our next question. Our next question comes from Brett Fishman with KeyBank. Your line is open.
Hey, good morning, everyone. Thanks for taking the questions. Just maybe moving past the segment conversation, I think at a high level, you noted that revenue from the cross-selling or XBU customer base was up 9% year over year in 2025. So, I was curious if you could maybe dive in a little bit. I'm curious how big that group of customers is as a percentage or total, and then And maybe any other caller on what you think drove that excess 400 dips of growth within that cohort relative to total company?
Yeah, Brett, we've got several activities going on across BU. We've got, you know, several hundreds of customers that are doing business across both platforms. And then we also, within that, we have strategic pilots of some key segments that we're really looking to accelerate on. So we've seen significant growth, as I said, the 9%. But even within those pilots, it's even greater than that. The team's doing a really good job in leveraging the value prop across the TerraHealth and being able to bring the capabilities end-to-end. We continue to look at our customer satisfaction scores. Sterigenics overall, well, I'd say, first of all, the company, they're over 80% overall. Sterigenics numbers were even significantly higher last year, and the XBU customers continue to be above that average. So we'll continue to look for opportunities to accelerate that. We've got a lot of commercial work going on with the teams, And we're hopeful to see even more rewards from that in 2026.
And then for a follow-up, maybe just thought I'd bring up capital allocation. I think, you know, the story continues to get better here and, you know, net debt and net leverage are continuing to gradually improve. So just wondering if there's, you know, any slight marginal change in how you're thinking about, you know, further activity here in terms of, like, organic investment and debt reduction versus the potential to see maybe a bolt-on acquisition this year. Thank you very much.
Yeah, thanks, Brett. But, you know, our priorities are staying the same as what we told you before. Our first priority is to fund organic investments and making sure we're getting the appropriate returns on that. We committed to a free cash flow target for the 25 to 27 period. We're still committed to that today. And the guide that we gave you in Outlook for CapEx for 2026 fits within that framework. So, you know, the business will continue to do well and generate cash flow and be prioritized as we've talked about in the past.
Operator
Thank you. One moment for our next question. Our next question comes from Max Mock with William Blair. Your line is open.
Hi, good morning. It's Christine Rains on for Max Mock. Just hoping to circle back to your two active stereogenic growth projects. On the x-ray facility, knowing the past, you've pointed to a roughly 40% customer utilization target before breaking ground. And it's said that the project did not meet the threshold, but obviously it's strategically important. So, here's how much below that 40% typical benchmark you're currently seeing, and if you're assuming a margin dilution for the segment in 2027 until utilization ramps, and then also if you can give us some call around the sterilization modality for the other facility build. okay i'm sorry you've got like seven questions within that one let me try to break this down a couple perspectives okay thank you yeah okay that's okay let me just walk through it we we've stated in the past we target uh 40 percent um you know before we put shovels in the ground 40 utilization you know that's what we hope to have committed with our customers this one's a little
bit lighter than that one we've also said we target 20 ir on our investments obviously if we're putting cobalt in an existing facility or an EO chamber in an existing facility that's above the 20%. Greenfields are below that. This one will be below that, obviously, because it's a complete greenfield. Strategically, it's important because we think there's some segments of the market that would like x-ray, and we're bringing that service to them. We still think that the other modalities will be, by and large, the largest segments and modalities. We will see this ramping up in the second half of the year. I'm trying to get all through all your questions. On sterigenics margins, so, you know, John mentioned that we'll have slight margins improvements in 2026, and, you know, that'll be driven predominantly by sterigenics, where we sit today. That encompasses some of the costs that will come in with low volumes on the x-ray facility, and we'll see that phenomenon continue as we look into 27 as well. So, I think I've addressed all of them. I don't know if I've missed anything else.
Yeah, no, I think you got the majority of them. I was just wondering if you have any color on the sterilization modality for the other facility. I think your deck pointed to two growth projects in Sterogenics.
Oh, the second facility. No, we have not gone ahead into detail. We're working with our customers on that facility, and we have not gone ahead and publicly released what kind of facility or where that's going to be at this point in time.
Got it. Thank you for taking our questions.
Operator
One moment for our next question. Our next question comes from Casey Woodring with JP Morgan. Your line is open.
Great. Thank you for taking my questions. Maybe the first one, just any changes on how you're thinking about the competitive positioning and serogenics in light of Nishap? I know that that was the focus coming out of the last analyst day, just in terms of opportunity to gain share from smaller players. And then maybe same question on the Nelson side. Maybe just walk us through the latest and greatest on the current competitive landscape there.
Thanks, Casey. On the stereogenics competitive scenario, I would say, as I mentioned earlier in my comments, NESHAP has got a two-year extension period. So we're seeing discussions about insourcing and outsourcing slowing down. That doesn't mean customers aren't having discussions with us overall on what their strategic plans on their supply chain. Those have always been ongoing. But I don't think there's the urgency that people saw when, you know, the April 2026 deadline was in place that's now been extended. You know, we continue to compete very well. Our customer satisfaction scores were up significantly last year versus the prior year. We'll see how 26s are when we do the surveys here coming out shortly. But overall, I think Sterigenics is well positioned. And, you know, it's the strength of the business model it's the global platform it's consistency in our quality systems it's our ability for our customers to contract with us on a global basis and us being a full service provider that helps take care of them in all modalities and all geographies so I would I would say stereogenics is continues to be very well positioned on Nelson labs you know Nelson labs is you know very fragmented market overall but that business is really good at service and quality and their reputation is what really matters there with science, and the team continues to do very well. We've got pockets in that business. As you know, the core lab testing has improved over the last year. The advisory business has been a little bit more choppy because of some of the remediation projects that have come and gone based on some of the FDA activity. But overall, we continue to accelerate in the marketplace. Our customer stat scores are good. Our NPS, we also do an NPS, a net promoter score. And that continues to perform very, very well. So I'd say, you know, we're very well situate, but it's a different dynamic, Casey, in that market. It's a more fragmented market on a global basis. But we do, you know, we do 800, 900 tests in that business across our facilities around the world.
Got it. Understood. And then maybe just a quick follow-up. Any update in terms of the timing of when we could expect any updates on the litigation front?
Thank you. um no i mean there's nothing material to change on timing um you know i think when i look at it there's no trial set for this year other than the public nuisance case in new mexico in the july time period other than that there's a material change in timelines thank you one moment for our next question our next question comes from jason bednar with piper sandley your line is open hey good morning thanks for taking our questions um mike i wanted to come back to one of the comments you made just on the you're responding to the first quarter sterigenics guide just to
unpack the comment if you could around the slower start to the year and the weather headwinds on sterigenics were those were those comments connected or was that something where you're saying demand was a little bit slower to start the year and weather has been creating some challenges as well and then for the weather comment in particular just if you can quantify how large is that headwind is that something that you've like you feel like you can overcome here within the first quarter, or does it take a couple quarters to, you know, overcome and catch up on that impact or those headwinds?
Yeah, Jason, good morning. I would say a couple of comments. My comments were focused around we have some shutdowns in the quarter and weather has had some impact that we felt. The guide that we gave today, mid-single digits, is consistent with what we feel we can deliver, and also the guide for the year mid- to high single digits is we're confident in our ability to deliver that as well. So I would say that's how you should think about it.
Okay, fair enough. And then maybe longer term or maybe medium term to long term, wanted to ask in the context of future CapEx and free cash. You have a couple of capacity expansion plans underway. We've been talking about those here today. I guess, do you still feel comfortable with those long term targets? I think you do. I'm just reiterating them today. But just how do you think about those in the context of medium term, long term planning for additional capacity expansion? When do those additional capacity expansions or greenfield opportunities, when do those discussions happen? How are you planning for those today, knowing you're looking out to 28, 29, and 30? Hopefully that question makes sense.
I think I got it, Jason. So as I mentioned multiple times as well as this morning, we do a three-year strap plan with our leadership team and the board every August, and we kind of lay out the next three years of where we see the capital demands. and that really was the foundation of the investor day presentation we gave for the 25 to 27 time periods we continue to roll forward and look at opportunities beyond that we continue to make sure that we've got the facility capacity in place delivered a long-term growth that we need so you know we will continue to refresh that and provide updates where appropriate on future outlooks but for the time periods that we've given guidance around 25 to 27 you know we we feel confident in our ability to deliver the free cash flow that we've outlined in that, in that time period. All right. Got it. Makes sense. Thanks so much. Congrats again.

Great. One moment for our next question. Our next question comes from Ryan Halstead with RBC Capital Markets. Your line is open.
Morning. Thanks for taking the questions. Maybe just to ask a question on the Nordian segment. Can you maybe provide a little more color on some of the headwinds you saw on the quarter, certainly, especially given that, you know, you were going up against maybe some lighter comps. You obviously talked about the timing of the Cobalt 60 harvest schedule, you know, maybe just any color around, you know, what were the drivers there, including that timing impact?
You know, Ryan, I would just, Michael, I would just say it was driven by, it was driven by harvest schedules, right? We called this, we expected it to be down. It's really, you know, it's not a demand problem. It's a supply timing situation. So remember how this works. You get cobalt out of nuclear reactors. The primary purpose in life is to generate electricity for consumers and businesses. So we work with utilities on when they're going to do a shutdown so we can harvest the cobalt out of the facilities, out of the reactors. So we have very good visibility that will shift every now and then a couple weeks or months here and there but we have good visibility so we anticipated this we projected that to the investment community to make sure they understood it so we're not concerned at all about the fourth quarter from a buying perspective we knew that and we had good visibility and that's why we also give you visibility on how we think of first half second half so you could start to circle in and honing on how those those harvests will work in the year to come all right so I But there was no surprise about that. Overall, you know, it came in as expected or actually slightly better even.
Got it. That's helpful. Thank you. And then for my follow up, just any updated views on the potential impact of onshoring by your customers, especially, you know, given the dynamic environment with tariffs and the government may be proposing some regulations with incentives for manufacturers to, you know, try to bring more of that manufacturing onshore. Just curious, your thoughts on impact to your business.
Yeah, great. So, remember, the majority of our business is a service business. We're not really impacted by tariffs. The one place where we have product is the COBOL product, and that's USMCA certified, so we don't have any tariffs. I just want to kind of level set that. Now talking about the bigger macro environment, we have not seen a significant movement of the onshoring, but if that were to happen, and customers are having discussions with us, but we're not seeing a significant investment commitment at this point in time. But if it were to happen, we'd be very well situated because we have a very significant position in the marketplace. here in the United States. Well, we'd anticipate that, assuring if it were to occur, would happen here.
Great. Thank you. Appreciate all the color.

I want a moment for our next question. Our next question comes from David Windley with Jeffries. Your line is open.
Hi, good morning. Thanks for taking my question. Michael, I was wondering, in regard to the guidance, where are your areas of higher or lower visibility, or said differently, what could firm up as the year progresses that takes you to the higher end of the range.
Yeah, David, it's pretty consistent year in and year out. It's not like a broken record, but it's volume. It's the volume and mix piece that would tend us towards the high end. As you know, Nordian, we have probably the best visibility. Sterigenics, less so. We've got, you know, a quarter or so out. And then in Nelson Labs is more transactional in nature, and some of those validation projects could take a little longer. So I'd say in that order. But the biggest thing that could drive us to the higher end of that would be volume and mix in Sterigenics and Nelson Labs.
And if I asked you to take that down a level, would you, like between, you commented on this a little earlier in the call, but like med device versus bioprocessing, you know, your kind of end markets, is one of those firming up or accelerating more than the other vis-a-vis visibility?
You know, I got to think about that. you know, we're seeing bioprocessing with nice growth, but we're in a pretty small share position. Maybe we picked our sales guys, we think we picked up a little share. I'm not sure we have, but we're seeing nice growth overall in there, but it's a small category. I'd say they're both in a pretty good spot right now, David, but just recognize bioprocessing is a much smaller base for us.
Yeah. Yeah. Okay. Thank you.

One moment for our next question. Our next question comes from Michael Pollack with Wolf Research. Your line is open.
Good morning. One of the things I heard on Sterigenics was the commercial segment volumes are challenged. Michael, can you unpack that? Remind us what product categories or commercials is food and consumer products or something else and, you know, what those challenges are, why you perceive them to be.
Yeah. So, Mike, yeah, that's reflecting on the comment I made earlier. Commercial is exactly what you talked about there's some electronics in there there's some food in there there's some spice in there there's some other categories as well that it's just been a choppy market coming out of COVID it really hasn't been very stable it's been moving around quite a bit we continue to see that going forward here and we're planning around that but I would say that that would be it now again it's a small portion of the total I think it's less than 15% I can't remember what the exact numbers it's it's a small portion stereogenics and context-wise helpful just to follow up to that and then one other topic please um when you say challenge like growing growing but just low growth or or shrinking uh combination i'd say more probably shrinking than growing i mean it's been shopping some customers have redesigned products and don't have the need um you know i can think of if i say this I'm thinking of one customer that had some, you know, a packaging product for the food market and they've changed their designs coming out of COVID. But, again, that's not impacting 2026. That's just I'm looking backwards when I make that comment. So it's just been, you know, there's a churn in that customer base. And we're seeing it. It's just a little heavier than we've seen in the past. But it's been like this since 2020, 2021.
I appreciate that color. And then the other one, also, Sterigenics, just as you reflect on calendar year 25 and the performance and the acceleration and volume growth, the topic of tariffs, you know, we've discussed on prior calls, do you believe the tariff landscape contributed to customers kind of building some inventory ahead of that as part of their mitigation plans? any what's the latest perspective on whether that was you know good neutral in last year thank you yeah we'd see as we've stated a couple times we've not seen a material impact from the tariff side that we've been able to detect I referenced in the second quarter there was you know a bump up at some stat
volume with it in a particular facility I was the ending and I say hey what happened here and they said all that you know customers trying to get some stuff in before Terrace, but that's not, you know, that's a facility that's got 50 customers. This was a customer that I happened to notice when I was going through some analytics with the team out there. We're just not seeing material impact from that, Mike. I know people have asked us that question, and there's nothing consistently showing up from our customers. We're seeing, you know, nice, consistent volumes on the Sterigenics site as we wrapped up 2025, which was good. Thank you.

And I'm showing you further questions at this time. I'd like to turn the call back to Michael for any further remarks.
Thank you. Great. We thank you for your time this morning. You know, hopefully you can see we have a nice finish to 2025. We're set up for a very strong 2026. And what I want you to take out of this is this business is built to perform. We've had 20 consecutive years of growth, strong cash flow generation, strong margins, sticky customer relationships. This business is built to run and perform. And what we're going to try doing is making sure you have transparency of what we expect out of the business. And we're just going to keep executing against it. So thank you for your time today and wish you all a good week. Bye-bye.
