Okay, thanks, Brian. And hello, everyone. I'll start by walking through our first quarter results, which are detailed on Slide 3 of the supplemental information available on the Investor Relations page of our website. And unless otherwise noted, all year-over-year revenue growth figures discussed today are presented on a constant currency basis. As Brian noted, our first quarter performance was in line with our expectations, and we anticipate continued momentum through the rest of 2025, particularly with our labs business, where we see strong recurring revenue with long contracts and a loyal customer base. Let me begin by taking you through our first quarter performance, followed by a discussion of our full year 2025 financial guidance, which remains unchanged. After that, we'll open up the call for questions. Total reported revenue for the first quarter of 2025 was $693 million, compared to $711 million in the prior year period. The year-over-year decrease in total revenue was primarily due to lower COVID revenue and lower donor screening revenue related to the planned wind-down of that business. Excluding COVID and donor screening revenue, we achieved mid-single-digit revenue growth of 6%. This performance was primarily driven by strength in our labs business, as well as consistent growth in immunohematology and a strong flu season. Foreign currency translation had an unfavorable impact of 150 basis points during the first quarter. From a regional perspective, our Q1 revenue performance was led by our other region, which is comprised of Japan, Asia-Pac, and Latin America, with 12% growth, driven by strong 17% growth in labs revenue. And looking at our other regions, North America declined by 6% compared to the prior year period due to the year-over-year decrease in COVID revenue and the ongoing wind-down of our donor screening business. But absent these headwinds, North America grew by 5%. Europe, Middle East, and Africa grew 9%, driven by strong contribution from labs and immunohematology. Finally, China revenue was flat compared to the prior year period, primarily related to order timing and a decrease in triage revenue related to lower reimbursement rates for certain cardiac markers. Labs revenue in China grew 2%, with strong contribution from clin chemistry testing. We continue to expect mid- to high-single-digit growth in China for the full year, assuming no change in the current tariff situation. Now looking at our non-respiratory business in the first quarter of 2025, revenue grew 2%. Now within that non-respiratory category, our labs business grew 7%, driven by good performance in both clin chemistry and immunoassay testing. We had strong recurring revenue growth, which was partially offset by an approximately $8 million decline in instrument revenue due to order timing. Non-core revenue was flat year-over-year, with an increase in collaboration revenue offset by a timing of contract manufacturing revenue. In transfusion medicine, immunohematology revenue continued its consistent growth of 4%, with particular strength in Europe, Middle East, and Africa. Donor screening revenue declined by 62% due to the continued wind-down of that business, as expected. And then lastly, our Triage business performed nice, up 9% year-over-year. Turning now to our respiratory business, revenue of $120 million grew 11%, excluding COVID. We saw strong flu sales in Q1, with year-over-year growth of 18%. COVID revenue was $23 million during the quarter, which was a 53% year-over-year decline. Moving down the P&L, Q1 '25 adjusted gross profit margin was 50.1% versus 47.5% in the prior year period. The year-over-year increase was primarily driven by product mix, with higher margin contribution from flu and COVID flu combo test. Non-GAAP operating expenses of $233 million, including SG&A and R&D, decreased by a net $18 million compared to the prior year period, which resulted primarily from our ongoing cost savings actions. The primary areas of savings included staffing reductions, decreased travel, and lower outside services expense. Adjusted EBITDA was $160 million compared to $132 million in the prior year period. Adjusted EBITDA margin was 23%, a 450 basis point improvement, which again reflects the cost savings actions we have taken. And adjusted diluted EPS was $0.74 compared to $0.44 in the prior year period, which is a 68% year-over-year improvement. Turning now to the balance sheet on Slide 5, we finished the quarter with $127 million in cash and $250 million in borrowings on our $800 million revolving credit facility. Reminder, our capital allocation priority continues to be debt pay down. Our first quarter of '25 adjusted free cash flow was $47 million, which represents 29% of our adjusted EBITDA and 94% of adjusted net income in the quarter. This is in line with our previously communicated targets. During Q1, our net debt to adjusted EBITDA ratio decreased sequentially from 4.4 times at year end '24 to 4.2 times. Our consolidated leverage ratio, including pro forma EBITDA adjustments, was 3.4 times as permitted and defined under our credit agreement. Now, turning to Slide 6, based on our current business outlook, we are maintaining our full year 2025 financial guidance as follows. We expect gross tariff impacts of $30 million to $40 million to be neutral to our overall financial results based on the expected mitigation plans that Brian discussed earlier. We continue to expect full year 2025 total reported revenue of between $2.6 billion and $2.81 billion. Note that the U.S. dollar has weakened since year end 2024, creating an opportunity for FX tailwinds of approximately $26 million. However, we are leaving total reported revenue guidance unchanged at this time due to current currency volatility. We continue to expect COVID revenue of between $110 million to $140 million. This assumes that we see a summerslide of COVID activity as we've seen in the past two years. Of course, we will monitor this closely and will look to mitigate any impact with further cost reductions if the seasonal cases don't materialize as expected. We expect adjusted EBITDA between $575 million and $615 million, which equates to 22% adjusted EBITDA margin, which is a 250 basis point improvement over full year '24. And we expect adjusted diluted EPS of between $2.07 and $2.57. Other key points related to our assumptions for full year 2025 guidance include, we assume a typical quarterly seasonality with Q2 revenue being our lowest quarter, Q4 being our highest quarter for revenue and margins. And further, we expect Q2 performance in China to be lower compared to the prior year period due to our decision to delay some shipments early in this quarter as the tariff situation evolved. Since then, regular shipments to China have resumed and we do not expect any impact on our full year 2025 guidance. Again, this is timing only between Q2 and second half 2025. We assume cost savings of approximately $50 million in the first half of 2025 as part of our previously implemented $100 million annualized cost savings initiatives. We continue to expect incremental cost savings in '25 between $30 million to $50 million primarily related to procurement efforts. And again, this is in addition to any tariff related offsets. We assume positive adjusted free cash flow for the full year '25 to be approximately 25% to 30% of adjusted EBITDA conversion and approximately 100% of adjusted net income. We expect higher cash flow in the second half of '25, which is in line with seasonally higher revenue and the realization of our cost savings. And we continue to target free cash flow conversion of 50% of adjusted EBITDA on the same timeline as our margin improvements. We also continue to expect our net debt leverage ratio to between 3.5x and 4x by year end. And since our credit facility matures in May of 2027, we plan to refinance the debt sometime in the second half of 2025 or early '26. Timing of this refinancing, of course, depends upon market conditions. So in summary, our continued operational improvements played a meaningful role in our performance this quarter. We're actively navigating a fluid macro environment and believe our current business outlook is in lockstep with our 2025 full year financial guidance. Looking ahead, we remain focused on execution, commercial excellence, and cost savings initiatives to deliver profitable growth. And despite recent macro challenges and the impact of tariffs, we continue to see a clear pathway to our adjusted EBITDA margin goal in the mid to high 20% range over the next couple of years. With that, I'll ask the operator to please open up the line for questions.
