And now I'd like to turn the call over to our CEO, Brian Blaser.

Thanks, Juliette. Good afternoon, everyone, and thank you for joining us on the call today. We finished the year with solid top-line results that were in line with our 2024 financial guidance, and I'm encouraged by the progress that we're making in improving our cost structure and focusing the business to elevate profitable growth. Today, I'll discuss our 2024 operational highlights and key priorities for 2025, and then Joe will provide greater detail as we share our 2025 full-year guidance. As I mentioned in previous calls, I've been driving an operating model designed to empower our leadership team to focus on growth and profitability. As part of this strategy, I made key changes to the leadership team to ensure we have the right mix of talent and expertise to move our vision forward. Having the right leadership in place is essential for driving innovation, improving operational efficiency, and positioning the company for success. Our efforts to prioritize high-impact opportunities are showing early signs of progress, as reflected in our second half 2024 results. Turning to the fourth quarter of 2024, we saw ongoing contribution from our labs, Immunohematology, and Point of Care businesses. Total reported revenue in Q4 was $708 million, which decreased by 4% year-over-year due to the expected declines in COVID and flu testing revenues. Importantly, over 90% of our Q4 sales were recurring, driven by reagents, consumables, and service. And I'd mention that all growth rates I'm about to give are in constant currency. Our Labs business, which is roughly 50% of our total company revenues, achieved growth of 4% on a reported and constant currency basis excluding COVID and non-core revenue. This performance underscores its durable and predictable business model with strong brand recognition, long-term contracts, and a loyal customer base. Within transfusion medicine, our Immunohematology business continued to drive stable growth of 4% during the fourth quarter. And despite challenging year-over-year comparisons from the decline of COVID testing, our Point of Care business continues its leadership position with Sofia's large global installed base and our flu COVID combo test. And lastly, in our molecular diagnostics business, we initiated clinical trials for our Savanna Respiratory Panel last month, which coincided with the ramp-up of this year's respiratory season. We expect to complete our trials over the next few months as the season runs its normal course. Adjusted EBITDA for the fourth quarter 2024 was $150 million, which represents a 21% adjusted EBITDA margin and adjusted diluted EPS of $0.63. As we continue to move our business forward, I've spoken about our three central priorities: delivering the best experience for our customers, prioritizing execution on a small number of high impact programs, and driving profitable sustainable growth. These priorities include improving R&D productivity and the strength of our platform content as well as development of new systems that will enable us to strengthen our global market position. In addition, we continue to drive cost reduction initiatives that we started in 2024, including realizing the remainder of our previously announced cost savings by midyear and implementing new actions focused mainly on procurement and gross margin improvement. We expect these programs to drive margin growth over the next few years that will achieve benchmark levels of profitability. In closing, I have been impressed with our team and grateful for their support as we made difficult but necessary changes this past year. Despite challenging circumstances, our team has been resilient and determined to build an innovative, enduring company that's focused on supporting our customers and their needs. I look forward to sharing our progress on our operational and financial results as we move through 2025. And with that, I will hand it over to Joe to discuss our 2024 financial performance and guidance for 2025.

Okay. Thanks, Brian, and hello, everyone. I'll begin with the details of our fourth quarter and full year 2024 results on Slides 3 and 4 of the earnings presentation, which is currently available on our IR website. Again, unless stated otherwise, all year-over-year revenue growth rates on today's call are provided on a comparable currency basis. During the fourth quarter and full year 2024, our business performed in line with our expectations, and we expect continued momentum going into 2025. I'll start with some high-level commentary on our full year 2024 performance and then drill down into fourth-quarter results. We'll also provide our estimated full year 2025 financial guidance, and then of course we'll open up the call for some questions. Total reported revenue for the full year 2024 was $2.8 billion, including $2.3 billion in non-respiratory revenue. Labs growth was 4% excluding COVID and non-core revenue, which includes contract manufacturing. And our respiratory revenue was $504 million, which grew 4% excluding COVID compared to the prior year. Full year 2024 COVID revenue was $185 million, including $17 million in government contracts. Foreign currency exchange negatively impacted full year 2024 results by 60 basis points. Adjusted EBITDA was $543 million and a 19.5% adjusted EBITDA margin, and adjusted diluted earnings per share was $1.85. Moving now to fourth quarter 2024 results. Total reported revenue was $708 million, which decreased by 4% compared to the prior year period due to lower year-over-year COVID and flu revenues as discussed in our third quarter earnings call. Foreign currency exchange negatively impacted fourth quarter results by 30 basis points. From a regional perspective, our fourth quarter 2024 constant currency revenue performance was led by our other region, which again is comprised of Japan, Asia Pacific, and Latin America and grew 13%. China grew 11%, driven by strong labs performance in China was partially offset by softness in cardiac point of care products, resulting from the timing of certain orders and reimbursement changes in some Chinese provinces that we discussed on our third quarter earnings call. I note that for the full year, China excluding respiratory grew in the high single-digits as expected. Our Europe, Middle East, Africa region declined by 6% due to a one-time item and timing of revenue in the prior year period. For the full year 2024, Europe, Middle East, and Africa region revenue grew by 2%. And then finally, North America declined by 11%, compared to the prior year period due to the anticipated year-over-year decline in respiratory revenue, and the decline of U.S. donor screening revenue as we continue to wind down that business this year. For the full year 2024, North America was down 3% excluding COVID. Now looking at our non-respiratory business, which includes labs, transfusion medicine, and cardiac Point of Care products, fourth quarter 2024 revenue was relatively flat year-over-year. However, underlying labs revenue growth was 4%, excluding COVID and non-core revenue. In transfusion medicine, Immunohematology revenue grew 4% and Donor Screening declined by 40%. Cardiac revenue declined by 9% in Q4, primarily related to order timing in North America. For the full year, cardiac revenue was down approximately 2% or only $3 million compared to the prior year. Our Q4 respiratory revenue declined 18% year-over-year. During Q4, we saw continued favorable product mix from our Sofia flu COVID combo test, and we had $44 million in COVID revenue. We saw a late start to this respiratory season, which is more in line with pre-pandemic trends, and we have seen the season become strong in February thus far. Moving down the P&L, I show fourth quarter 2024 adjusted gross profit margin of 47% versus 52% in the prior year period. The year-over-year decrease was primarily driven by higher COVID and flu sales in the prior year period, as well as bonus accruals in Q4 of 2024 that did not occur in Q4 2023 as mentioned on our Q3 earnings call. Non-GAAP operating expenses of $226 million, including SG&A and R&D decreased by $16 million compared to the prior year period, which reflected cost savings initiatives partially offset by the previously mentioned Q4 '24 bonus cycles. Adjusted EBITDA was $150 million compared to $195 million in the prior year period. Adjusted EBITDA margin was 21%, which reflects the cost savings actions we have taken, partially offset by lower revenue from respiratory tests, which are high-margin contributors. Adjusted diluted earnings per share was $0.63, compared to adjusted diluted EPS of $1.17 in the prior year period. This year-over-year change was primarily due to higher respiratory revenue in the prior year period and higher interest expense in the current period, partially offset by our cost savings actions. The full year effective adjusted income tax rate for 2024 was 24%. Now turning to the balance sheet. We finished the quarter with $98 million of cash. And as of the end of Q4, we had $198 million of borrowings on our $800 million revolver, which is a decrease of $32 million compared to Q3. Our capital allocation priority continues to be debt paydown. Fourth quarter 2024 adjusted free cash flow was $68 million, which represents 45% of our adjusted EBITDA in Q4. And our second half 2024 adjusted free cash flow was 59% of our second half adjusted EBITDA. During the fourth quarter of 2024, our net debt to adjusted EBITDA ratio was 4.4x, and our consolidated leverage ratio, including pro forma EBITDA adjustments, was 3.5x as permitted and defined under our credit agreement. Now I will provide our full year 2025 guidance. We expect full year 2025 total reported revenue of between $2.6 billion and $2.81 billion. Note that we expect a negative impact of $55 million related to foreign currency exchange, which was estimated using currency rates as of January 1, 2025, and is subject to change as the year progresses. We expect adjusted EBITDA between $575 million and $615 million, which equates to a 22% adjusted EBITDA margin. This is an expected 250 basis point improvement off of full year 2024. We expect adjusted diluted EPS of between $2.07 to $2.57. Additionally, we do not see significant currency impact to either adjusted EBITDA or adjusted EPS. Now these expectations are based on a set of assumptions as follows. We assume that the full year 2025 business unit growth profiles will be in line with the commentary we shared most recently in January at the JPMorgan conference, including the labs business expected to grow in the mid-single-digits, Transfusion medicine, excluding U.S. Donor Screening, expected to grow in the low single digits. Chronic hair growth, excluding COVID, is assumed to grow in the mid-single-digits. And molecular diagnostics is expected to continue to develop during 2025 with limited sales. As a reminder, we are not assuming any sales from U.S., Savanna, or respiratory products in 2025. And lastly, we assume mid to high single-digit growth in China. Now for the respiratory revenue in 2025, we assume a $50 million to $55 million overall test market with greater than 50% of flu product revenue coming from our flu COVID combo test. We are seeing strong recent flu trends in Q1, which are factored into our full year guidance presented today. In addition, we assume full year 2025 COVID revenue will be in the range of $110 million to $140 million, which excludes approximately $17 million in government contracts that we had in 2024 and do not expect to repeat as well as lower retail sales, which account for less than 0.5% of our total company revenue. In addition, we assume typical quarterly seasonality with Q2 revenue being our lowest quarter and Q4 being our highest quarter for revenue and margins. We assume cost savings of approximately $50 million in the first half of 2025 as part of our previously implemented $100 million in annualized cost savings actions. We expect incremental cost savings in 2025 between $30 million to $50 million primarily related to procurement. The majority of the $100 million in annualized savings that we implemented in 2024 was related to staffing reductions of 9% of the total workforce. Future staffing reductions are expected to be a part of our ongoing efforts to appropriately size our teams, and we will continue to evaluate staffing reductions as part of our ongoing margin improvement efforts. However, we are now turning our attention to procurement and other categories of cost to improve margins. We assume positive adjusted free cash flow for the full year 2025 to be approximately 25% to 30% of adjusted EBITDA. We expect higher cash flow in the second half of '25, which is in line with seasonally higher revenue and our cost savings initiatives. And we continue to target free cash flow conversion of 50% of adjusted EBITDA on the same timeline as our market improvement. We expect our net debt leverage ratio to be down close to a half a turn in the first half of '25 versus year end '24, and we expect it to land between 3.5x to 4x by the end of 2025. We assume full year interest expense to be down slightly from 2024 in the range of $158 million to $162 million. We had expected interest expense to be approximately $5 million to $7 million lower than this range, but higher than expected revolver borrowings at the end of '24 will carry over in '25. These higher borrowings are primarily related to one-time cash used for employee severance costs, our system conversions as well as the delay in proceeds related to the sale of a facility. Again, our capital allocation priority continues to be paying down debt. We assume CapEx of approximately $160 million to $170 million excluding instruments under reagent rental agreements and integration-related expenses. And finally, we assume a full year effective tax rate of 24%. To summarize, we believe our second half 2024 performance demonstrates solid progress towards our adjusted EBITDA margin expansion goal of greater than 25% over the next couple of years. We remain focused on our execution and cost savings initiatives to achieve our margin expansion and profitable growth goals. With that, I'll ask the operator to please open up the line for questions.

The first question comes from Jack Meehan with Nephron Research.

Thank you. Good afternoon. First question was on the guidance. The forecast for free cash flow conversion at 25% to 30% of adjusted EBITDA. It wasn't that long ago that you were looking at something closer to 50% of adjusted EBITDA conversion. I know that was a different time, different revenue base. But I was wondering if you could just talk about where you think that can go over time and what a more normalized level might look like?

It's Joe. Thanks for the question. Yeah, the cash flow is certainly not where we wanted to be. We ended 2024 at 20% recurring free cash flow as a percentage of EBITDA. And again, as you just stated, for 2025 we expect it to be between 25% to 30%. So it's an improvement over 2024, but ultimately our goal is to be at least 50% conversion of adjusted EBITDA to free cash flow conversion. And I believe that getting to that target will be over the same timeline as our margin improvement goals, so I would say over the next couple of years.

Okay. And then, I was hoping you could also just talk about the China region. So given some of the market uncertainty, the fourth quarter actually looks like it was pretty good for you guys in the region. This mid to high single-digit target you have for 2025, can you just give us an update on your view on pricing and exposure to any VBT programs that are taking place?

Yes. Hi, Jack. This is Brian. China continues to be an attractive market for us, but it is a complex market, as you know. In the near term, we think that the risk of additional VBP pressure has largely passed us by at least for 2025. But we have seen some smaller impacts to cardiac reimbursement there that are mainly reimbursement versus broad VBP actions. I don't expect any more significant actions on either VBP or reimbursement, but I would say that the competitive intensity there just given what has happened has increased. And as a result of that, we're kind of tempering our view from single-digit to mid-single-digit moving forward given that the nature of the environmental dynamic there.

Okay. That makes sense. If I could squeeze in one more just a clarification. I think there was a new disclosure in the slides for the cardiac revenue. I just wanted to clarify, does that include both Triage and BNP and kind of the decline you had in the quarter was entirely on the Triage side, I assume?

Yes, that's right. Yeah, we referenced that growth or decline in the prepared remarks, Jack, so we had to put a slide in the PowerPoint deck that goes with the earnings call. And yes, when we talk about the cardiac, it's the combined Triage revenue as well as the BNP revenue and really all of the full year variances is in the Triage business. That BNP business is flat, $75 billion every year.

The next question comes from Patrick Donnelly with Citi.

Hey, guys. Thanks for taking my questions. Joe, maybe one for you on the cost side. It sounds like maybe some of the cost savings are coming a little earlier than expected this year as well. Can you just talk about the levers you guys are pulling to preserve and drive EBITDA higher the key ones as we work our way through this year and then obviously the ones that remain out there to drive EBITDA back to where you guys want it on the margin side?

The overall EBITDA margins are expected to increase by 250 basis points from 2024 to 2025. At a high level, the initial $50 million from the first $100 million we initiated last year will benefit the first half of 2025, with that amount being divided fairly evenly between operating expenses and gross profit. Additionally, we anticipate an extra $30 million to $50 million in savings for 2025, primarily related to procurement, most of which will impact operating expenses since these are mostly indirect procurement savings. Direct procurement savings that will support gross profit will take longer to materialize, likely starting to show in 2026. These are the two main factors enhancing margins. However, we also face challenges such as normal merit increases for employees and 1% to 2% inflation on materials that will offset some gains. These are the main considerations as we transition from 2024 to 2025, leading to a projected 250 basis point improvement in EBITDA margins.

Okay. That's helpful. And then, maybe just the range on respiratory. Can you talk about the different drivers there? Are we in the endemic? Is this the right number to think about going forward? And then, inside of that, just Savanna, it sounds like respiratory trials for now, not much this year, the contribution there as we work our way forward?

Yes. I can take that. Maybe I'd take the COVID revenue piece first. We do believe that when you look at the COVID revenue for us, it is going down in '24 '25. But really, all of that drop from '24 to '25 in the COVID revenue is the government contract that won't repeat that we saw in '24. And then the other piece is retail revenue, which is a really small piece of our business. It's less than 0.5% of our total company revenue. And quite frankly, it's just not really a big focus of ours right now. The professional COVID revenue is relatively flat in our guidance, '24 '25, and we believe that's really at what I would describe as an endemic level. As far as the rest of the respiratory revenue, it's growing in the guidance. It's growing roughly low single-digits for '24, '25, when you think about flu, RSV, and strep.

The following question comes from Bill Bonello with Craig-Hallum.

Hi, thanks guys. I just want to follow-up a little bit on the first question that Patrick asked, maybe slightly differently. The margin expansion target is now a lot better than what you had said not long ago. And it would seem like you had anticipated additional cost savings; you've been talking about that and procurement, as an opportunity. So I'm just curious, two things, sort of what's going better, what has you more encouraged than when you originally talked about maybe 150 to 200 basis points? And then secondly does it change your thinking about the total opportunity at all?

Hey, Bill, this is Brian. In terms of what's improved, we can highlight many accomplishments from the past year. The significant staffing reductions we implemented, which amounted to 9% of our workforce, effectively resulted in a cost reduction of about 12% to 13%. We quickly addressed procurement, which has gained us significant traction and now allows us to discuss an additional $30 million to $50 million in savings. However, I want to be cautious and not get ahead of ourselves. I still believe we can reach our goal of a 25% EBITDA margin, potentially even higher, in the range of 25% to 30% over the next two to three years. That remains our objective, and we continue to push hard towards it.

Okay. That's helpful. And you talked about the procurement being more on the indirect cost side this year. Is there any color you can give on that at all? Like what types of things are you able to achieve there?

Yes. It's a lot of costs. It really cuts across the entire P&L. It's everything from supply chain and logistics costs, packaging to travel and entertainment costs. It really just cuts across the whole P&L. It's a lot of our service cost in IT and quality, etc., and even some R&D expenditures. So it really is a broad-based approach that we've taken to the indirect side. And the reason we're those are just a little bit more actionable in the short term than the direct procurement, which are generally product-related costs that require us to change in some cases the design or make regulatory submissions. And so they just take a little longer for us to implement.

Yes, that's helpful. Could you remind us why we saw a sequential decline in the adjusted gross margin?

From Q3 to Q4 in 2024 you're talking about, Bill?

Yes.

It's going to be mix. Yes, product mix. It's product mix.

Okay. But don't you have more respiratory in Q4 and isn't that higher margin? What

No, it's actually less, yeah, which is what we had talked about on the Q3 call.

The next question comes from Lu Li with UBS.

Great, thank you. So two questions. So first one on the margin. I just wanted to get your updated thoughts on the tariff. Is your assumption right now including any negative impact from the tariff or and then maybe just like any mitigation that you can talk about?

Yes. The tariff subject seems to be ever-changing here, over the last couple of weeks and we're monitoring it very carefully. We were happy to see that Mexico and Canada are moving, I think, toward a resolution to what was proposed by the administration. And as you probably know, our industry continues to lobby for an exemption there because the bulk of medical devices and diagnostic products are manufactured in the United States. We do have some exposure there, as we've got some instruments that are sourced from Mexico. But given the changing nature and morphing of the subject right now, it's really just too early for us to provide any real view of potential impact at this point. So we're just going to monitor it very closely and once we understand what the real impact is, we'll be able to provide additional guidance on that.

Got it. So, I wanted to circle back on one of your comments on the China part. So, you said risk of additional VBP pressure largely passed for 2025, and you don't really expect any significant action. Just can you just provide a little bit more detail in terms of what have you seen on the ground and why you believe that most of the impact should be gone in 2025?

Yes. So far, the VBP actions have primarily targeted liquid clinical chemistry products and immunoassay products. Our dry slide technology has not been affected by these actions. Unlike most competitors, our clinical chemistry and immunoassay mix is somewhat inverted. We have minimal immunoassay presence in the China market, predominantly focusing on clinical chemistry for our volume there. Given the timings of these actions, we currently do not foresee any significant VBP impact on our products for 2025.

Okay, got it. If I can squeeze one more, I just wanted to think about more the long-term margin expansion opportunity. So we're talking about like 250 basis points in 2025. Is that the right way to think about in terms of like 2026 as well, given that you do have more procurement opportunities that you just mentioned and then you also have the divestiture of the donor business? Just wanted to think about how you it sounds like a little bit longer-term 2026?

Yes. Hi, Lu. It's Joe. We've been, I think, pretty consistent here since Brian joined the company back last May in that we are targeting adjusted EBITDA margins greater than 25% and that it would be a two to three year journey from when he started with the company. And the reason that it takes that long, because it may be surprising to some of us, like, why would it take so long is because we can do the headcount actions fairly quickly, which we did. We can get to indirect procurement savings, which we will get to this year. It's the direct procurement savings that take a little bit longer because sometimes you're looking at bringing in, recertifying new suppliers or actually swapping in and out new materials on existing products and trying to avoid new 510(k) filings with the FDA. So it does take a little time. So I think we're making good progress from '24 to '25. We will make even more progress as we move into 2026 as we continue with the indirect procurement savings as well as start to see more of the direct procurement savings come through on the gross margin line. And then the final thing I would say is that we are going to get a bit of a tailwind as we fully exit from the donor screening business, the U.S. Donor screening business in 2026. We've sized that at roughly 50 to 100 basis points. And then the final thing I mentioned is, the Savanna launch. That will provide some tailwinds to margins as well as we start to move from dilutive impacts of the project to more accretive impacts of a molecular product margin. So all those things combined will get you to, again, that greater than 25% adjusted EBITDA margin. So we'll make progress this year. We'll make more progress next year. And I would think by the time we get to the end of '26, first half of '27, we should be where we need to be with margins.

The next question comes from Andrew Cooper with Raymond James.

Everybody, thanks for the question. A lot already asked, but maybe just one, just to make sure on the $30 million to $50 million of savings this year, that's an in-year number and I think you said second-half weighted. So is it right to think about as we move into 2026, there is some flow-through there on top of like you called out the incremental direct procurement work and so forth? So we should have again kind of another above fully normalized margin expansion year in '26. Is that the right way to think about it?

Yes, the $30 million to $50 million we mentioned is additional and will impact this year, primarily in the second half. Most of it will be related to operating expenses, particularly for indirect insurance. Additionally, we have several direct procurement projects underway that are expected to yield more benefits in 2026. As we transition through 2025, we will provide more details on what those impacts may be in 2026.

Okay, helpful. And then I'm going to sneak two together here. But maybe just on Savanna and the timing, I think you said you started the trial last month. That puts you a full kind of 10 months from when you first withdrew the submission last year. It's a little bit later than we would have thought given the typical respiratory season of what we've seen late would have kicked off a little earlier. Luckily, there is kind of a big February surge, it appears. But just how do we think about the timing there and potentially being ready for this next flu season if all goes right? I know you don't have anything baked in, but just kind of would love the thoughts there on what that could look like if it does. And then secondly, just very quickly, can you give us a little bit of color for the donor screening revenues assumed in the guide?

We initiated the Savanna trial in January. The flu season started to pick up a bit later in December this year than we anticipated. We aimed to launch the trial just before the peak flu season to ensure we could collect the necessary samples for a successful trial. The flu season is expected to continue for a couple more months, during which we'll gather samples and analyze the data. We plan to submit our findings for regulatory approval later this year, which would enable us to enter the market. There hasn’t been any change in our timeline for Savanna, and we don’t have much more to share until we advance further in the trial and regulatory process.

And then into the Donor Screening question you had, really no change from what we said on the Q3 earnings call that we expect that the Donor Screening business this year will be $40 million to $50 million in the U.S. The Donor Screening will be $40 million to $50 million and that's down quite a bit from 2024 where we finished at roughly $115 million. So it's quite a drag, but we'll get through most of the wind down this year. I think there'll be very little residual revenue that will fall into 2026. We should get through most of it this year.

The next question comes from Tycho Peterson with Jefferies.

Yes, hi. This is Jack on for Tycho. Thanks for taking our question. I guess first thinking about the longer-term margin target, how should we think about the tradeoff between building your longer-term growth engine, funding innovation beyond Savanna and sort of rightsizing the cost structure? What gives you confidence in the ability to get back to consistent mid-single-digits growth while also driving this new operating model?

Thank you for the question. I believe there is a direct connection between our efforts in margin expansion and our capacity to invest in the business's future through new product development, including assays content on our platforms and new systems. My initial focus was to ensure the organization concentrated on necessary cost improvements, getting Savanna on track, and managing several important projects related to menu expansion and lifecycle management. With the momentum we are gaining from our procurement initiatives, we are poised to enhance the strength of our product portfolio. While we are still in the early phases, we are defining innovation roadmaps for each of our businesses that include assays and new systems. We will provide further updates on our plans in upcoming calls. Additionally, I want to highlight that our underlying business model is quite solid, with stable mid-single-digit growth driven by strong customer relationships, a favorable win-loss ratio, and high renewal rates. These factors contribute to our overall growth, and any advancements we make with systems and new assays will build on this foundation.

Got into mid-single digits and labs for the year, are there any swing factors in play that could drive that to either lower or mid-single digit or higher end for instance China?

Yeah. Well, China is a dynamic market. Things change there quickly. I would say right now, I don't see anything again on the VBP front or the reimbursement front that would have a major impact there. And again, I kind of point to the stable recurring revenue dynamic of our business model that wouldn't point to any major swings in our labs business.

Yeah, I think I would only add that as a tailwind, menu is always going to drive incremental growth. So as we continue to reprioritize the R&D group on menu expansion, I'd like to think that there would be potential upside going forward. I wouldn't say this year because what we put out as a guide we're comfortable with. But moving forward, as you expand the menu, especially on the IA side that would drive additional growth.

The next question comes from Casey Woodring with JPMorgan.

Great. Thank you for taking my questions. I guess my first one, can you give us a sense of what to expect for 1Q across your different business lines and specifically on respiratory and flu in 1Q? What do you have baked in here there? ILI has been picking up as you noted. So curious if respiratory in 1Q could come in above where it was in 3Q since inventories are lower or if some of that was just pull forward in the fall? And then, I guess, if respiratory is expected to come in stronger here in 1Q, how are you thinking about the rest of the year, just given the unknowns around the '25, '26 respiratory season? Yeah, just maybe walk us through 1Q versus the rest of the year in respiratory?

Yeah. Hi, Casey. This is Brian. We're seeing the same thing that you're seeing, which is the ILI really spiking up here, and also the positivity rate is also almost double what it was last year. And I think it's higher or as high as the ‘17, ‘18 flu season, which was a pretty robust season for us. We got off to a late start, but now we've seen this peak, and the question is how quickly the peak will come down. I think just given how high it is, there's a good likelihood that the tail from the coming down from the peak will stretch out a little bit further. And I think that's supported to a certain extent by what we saw in the Southern Hemisphere this last summer. So we're watching it. And you just don't know what the duration of this season is going to be. So we assumed for our full year guidance an average flu season with a test size of 50 million to 55 million tests in 2025, which is kind of the average for us for the last three years. And that's what we've got baked into our full year guide.

The following comes from Andrew Brackmann with William Blair.

Hey, guys. Good afternoon. Thanks for taking the questions. A lot has been asked of Brian, maybe one for you, big picture. I think you've been in the seat now months or so. So I think you've had some time to do sort of a full review of the business. Any sort of change in how you're sort of thinking about this collection of assets on the whole, this being the right mix or any sort of changes in how you might be thinking about acquisitions, divestitures, cuts, things like that? Thanks.

Thanks, Andrew. Our focus really is on improving the operational performance of the business. I like every one of these businesses. I think they fit together well, again, giving us the capability to work across the entire patient care value stream and be in both centralized and decentralized testing. I think each of the businesses plays a different role in our portfolio. But largely speaking, our focus is on making each of them more profitable and each of them grow more. So in the short-term, I don't have anything really to say on business development opportunities. We're really just focused on improving the operation of the business at this point.

The final question comes from Conor McNamara with RBC Capital Markets.

Hello. This is Jose Ricardo for Conor. I just wanted to go back to the tariff conversation. Thank you for asking one of the next question. I know things have changed quickly since you spoke and the administration has different approaches to tariffs, depending upon the country. And you talked about some of the instruments that are sourced with parts from Mexico. Have you also looked into the exposure on the secondary level suppliers that provide you with procurement of process materials that you also incorporate into your manufactured instruments?

Yes. That's all factored into the analysis that Brian referenced earlier. It is all factored in there. Yes. And again, we don't see a lot of exposure for China or Canada. If there's any one country, where more exposure, it will be Mexico, including all those layers that you mentioned.

Thank you. There are currently no other questions in queue at this time. This concludes today's conference call. Thank you for your participation. You may now disconnect your line.
