Thank you, Jon, and good afternoon. I'd like to start with a review of the first-quarter 2025 results. Overall, we executed well during the quarter, which allowed us to deliver revenue and operating profit and margin ahead of consensus estimates for Q1. Net sales for the first quarter of 2025 were approximately $585 million, which represents a 4.2% decline on a reported basis versus $611 million in Q1 of 2024. On a currency-neutral basis, this represents a 1.5% year-over-year decrease and was primarily driven by lower sales in our Life Science Group. Sales of Life Science Group in the first quarter of 2025 were $229 million compared to $242 million in Q1 of 2024, which is a decline of 5.4% on a reported basis and 3.5% on a currency-neutral basis, primarily reflecting ongoing softness in the biotech and academic research market, particularly in the Americas. Currency-neutral sales decreased in the Americas and Asia-Pacific, partially offset by increased sales in EMEA. Our Process Chromatography business experienced mid-teens growth on a year-over-year basis. The strength in Q1 was due to the timing of customers' orders, and we continue to expect high single-digit growth for this area in 2025. Excluding Process Chromatography sales, Core Life Science Group revenue decreased 7.5% year-over-year and 5.5% on a currency-neutral basis due to the softness across the markets for instrument demand. Sales of the Clinical Diagnostics Group in the first quarter of 2025 were approximately $357 million compared to $369 million in Q1 of 2024, which is a decrease of 3.2% on a reported basis and effectively flat on a currency-neutral basis. Increased demand for our quality control products was offset by the expected lower diabetes testing revenue, and we currently do not expect further reimbursement changes in China this year. On a geographic basis, currency-neutral sales decreased in Asia-Pacific, partially offset by increased sales in EMEA and the Americas. Q1 reported GAAP gross margin was 52.3% as compared to 53.4% in the first quarter of 2024. The decrease in gross margin was primarily driven by restructuring expenses related to the workforce reduction announced during the first quarter of 2025. SG&A expense for the first quarter of 2025 was $209 million or 35.7% of sales compared to $215 million or 35.2% in Q1 of 2024. The decrease in SG&A expense was primarily due to lower discretionary spending and employee-related costs, partially offset by restructuring costs. Research and development expense in the first quarter was $74 million or 12.6% of sales compared to $66 million or 10.9% of sales in Q1 of 2024. The higher year-over-year R&D was primarily due to restructuring costs, partially offset by lower employee-related expenses. Q1 operating income was approximately $24 million or 4% of sales compared to $45 million or 7.3% of sales in Q1 of '24. Lower operating income is driven by higher restructuring costs, partially offset by the revenue mix, continued proactive expense management initiatives. During the quarter, interest and other income resulted in net other income of $28 million compared to the -- to net other income of $24 million last year. The change in fair market value of equity security holdings, primarily related to the ownership of Sartorius AG shares, contributed to our reported net income of $64 million or $2.29 per diluted share. The effective tax rate for the first quarter of 2025 was 23.3% compared to 21.8% for the same period in 2024. The higher rate in 2025 was driven by a geographical mix of earnings. Moving to the non-GAAP results. Non-GAAP financial measures, which exclude certain atypical and unique items that impact both gross and operating margins and other income, are detailed in the reconciliation table in our press release. First quarter non-GAAP gross margin was 53.8%, in line with consensus but lower than Q1 2024's results of 54.2%. First quarter non-GAAP operating margin was 10.8% compared to 9.7% in Q1 of 2024. The non-GAAP effective tax rate for the first quarter of 2024 was 20.6% compared to 22.4% for the same period in 2024. The lower rate in 2025 was driven by our geographical mix of earnings. Finally, non-GAAP net income for the first quarter of 2025 was $71 million or $2.54 diluted earnings per share. Moving on to the balance sheet. Total cash and short-term investments at the end of Q1 were $1,660 million compared to $1,665 million at the end of Q4 2024. Inventory at the end of Q1 was $790 million, up from $760 million in the prior quarter. For the first quarter of 2025, net cash generated from operating activities was $130 million compared to $70 million for Q1 of 2024. Net capital expenditures for the first quarter of 2025 were $34 million, and depreciation and amortization for the first quarter, was $38 million. Regarding free cash flow for the first quarter of 2025, we were pleased with the generation of $96 million, which compares to $30 million in Q1 of 2024. We continue to target full year cash -- free cash flow of approximately $310 million to $330 million for 2025. During the first quarter, we purchased 399,295 shares of our stock for a total cost of $101 million or an average purchase price of approximately $253 per share. In April, we purchased an additional 422,648 shares of our stock for a total cost of $99 million, or an average purchase price of approximately $234 per share. We will continue to be opportunistic with our buyback program and still have $377 million available for share repurchases under the current Board authorized program. Moving on to the non-GAAP guidance for 2025. We are updating our 2025 full year guide to reflect the Q1 results, the evolving state of academic and biotech research funding, and the impact of recent changes in the macro economy, including tariffs. We recognize that the recent macro changes are causing uncertainty and remain fluid. However, in the interest of full transparency, we're providing our best estimates of the impact of the known changes as of today. Overall, we now expect total currency-neutral revenue to be in the range of approximately a 1% decline to 1.5% growth or approximately 225 basis points lower than our previous guide. I'll start with the effect of the softer academic research funding as a result of changes in U.S. policy. We now expect these life science purchases to be more muted in 2025, in particular, demand for instruments as customers evaluate the impact of potential changes to government funding. We are also seeing reduced demand from biotech customers, particularly among small and mid-sized development stage companies that have become more conservative with equipment spending due to the increased volatility in the capital markets. As such, we now expect our Life Science business to be in the range of flat-to-down 3% for the full year, versus a growth of approximately 1.5% to 3.5% previously. Next, we are derisking our diagnostics growth outlook by approximately 100 basis points to reflect a softer macroeconomic environment, particularly in China, and now anticipate full year growth of approximately 0.5% to 2.5%. The net effect of the market softness in our business group is approximately a 100 basis point headwind to operating margin. Finally, the impact of tariffs. Our updated guidance considers tariffs that are in effect globally as of today and assumes no change in the current U.S. policy. The net impact of the tariffs is a 130 basis points headwind to operating margin, primarily due to U.S.-manufactured products that are imported into China. Included in this updated view are actions we are taking to partially mitigate the effects of the tariffs, such as surcharges, prepositioning inventory in certain countries, further regionalizing supply chains, and identifying additional in-region manufacturing opportunities. Factoring in the above, the updated full year non-GAAP gross margin is projected to be between 53% and 54.5%. Note that we were able to offset the impact from market softness through our actions, and the difference relative to our prior full year gross margin outlook, a 55% to 55.5% is entirely due to the impact of tariffs. Full year non-GAAP operating margin is projected to be between 10% and 12% included in this range are the above considerations that I just spoke of. Additionally, we continue to be on track to achieve a key development milestone in Q3 2025 related to Saber Bio, which, as discussed previously, would result in a one-time in-process R&D charge of $10 million. As a result of the recent weakening U.S. dollar, we expect less of a headwind to our revenue and operating income than our prior guidance. We now expect approximately a 100 basis points headwind to 2025 revenue, an approximate 20 basis points impact on operating margin versus the prior 40 basis point effect. We estimate the non-GAAP full-year tax rate to be approximately 22% versus 23% previously, due to the change in the equity value of Sartorius investment. With our updated outlook for 2025, we recognize that there are many moving pieces and the situation is evolving rapidly. There's a wide range of scenarios that could ultimately play out. That said, we're trying to be prudent and transparent in providing the key headwinds that we are currently seeing in the marketplace. Where possible, we are focused on mitigating the impacts from proposed tariffs and global trade disruptions to deliver results for shareholders. As you've seen in the past year, management's approach to guidance is to be realistic in setting expectations. While we are adjusting our 2025 outlook, this does not shift our focus from the significant opportunities we see in enhancing business performance. Driving consistent topline growth remains central to our strategy and a key enabler of substantial margin expansion. We are confident that our ability to improve operational efficiency and strategically optimize our footprint will allow us to capture 100s of basis points of margin expansion over the coming years. We're eager to share more about this opportunity and other critical aspects of our business at our Investor Day this fall. I'll now turn the call over to Norman for his remarks.
