Thank you, Adam. Let me start with a review of our Q1 financials. Revenue for the quarter was $3.3 billion, an increase of 5.3% compared to last year, driven by organic growth of 2.1% and the impact from net acquisitions of 3.7%, partially offset by foreign currency translation of 0.5%. Operating income for the quarter was $320 million or 9.7% of revenue, which is 14% on an adjusted basis. During the quarter, we had $73 million of restructuring charges and special items, primarily related to acquisitions and launch pad savings. Excluding these items and the amortization of $17 million, adjusted operating income in the quarter was $469 million or 14% of revenue, compared to $463 million or 14.3% of revenue last year. The increase in adjusted operating income was primarily due to demand and the LaunchPad savings, partially offset by higher personnel costs. The 20 basis point decline in adjusted operating margin included headwinds from inventory and weather, excluding which enterprise margins would have been up 60 basis points. The adjusted tax rate for the quarter was 22.5%, compared to 23% last year. We continue to expect our adjusted tax rate for full year 2025 to be approximately 23%. Net earnings for the quarter were $213 million or $2.62 per diluted share. Adjusted EPS was $3.84 in the quarter, up 4% from last year. Operating cash flow was $19 million in the quarter, compared to a use of $13 million a year ago. The increase in cash flow was primarily due to the timing of working capital. Capital expenditures totaled $120 million in the quarter. For the full year, we continue to expect the capital expenditure to be approximately 3.8% of revenue. Free cash flow for the quarter was a use of $108 million, compared to a use of $104 million last year. The first quarter is typically the company's lowest quarter for free cash flow. We continue to expect the free cash flow for the full year to be $1.1 billion to $1.25 billion. During the quarter, the company invested $211 million in acquisitions and partnerships and paid out $62 million in dividends. At quarter end, we had $369 million in cash, while total debt was $5.6 billion. Our debt leverage as of quarter end was 2.5 times gross debt to trailing twelve-month adjusted EBITDA, at the low end of our targeted leverage of 2.5 times to 3 times. Now I will review our segment performance beginning with diagnostics laboratory. Revenue for the quarter was $2.6 billion, an increase of 6% compared to last year, with organic growth of 1.6% and net acquisitions of 4.7%, partially offset by foreign currency translation of 0.3%. Organic growth was impacted by approximately 90 basis points from weather and one fewer revenue day, which is timing related within the year. Total volume increased to 3%, compared to last year, as organic volume contributed 0.9%, while acquisitions net of divestitures contributed 2.1%. Organic volume also includes the negative impact from weather and one fewer revenue day. Price mix increased 3% versus last year due to organic growth of 0.7% and acquisitions net of divestitures of 2.6%, partially offset by foreign currency translation of 0.3%. Organic price mix was up due to mix, as we benefited from an increase in test per accession and lab management agreement. Diagnostics adjusted operating income for the quarter was $428 million or 16.3% of revenue, compared to $418 million or 16.9% of revenue last year. Adjusted operating margin was down 60 basis points due to Invitae and weather. Excluding these items, adjusted operating margin would have been up approximately 50 basis points as the benefit of organic demand and the LaunchPad savings was partially offset by higher personnel costs. Invitae remains on track to be slightly accretive for full year 2025. Now I will review the segment performance of biopharma laboratory services or BLS. Revenue for the quarter was $721 million, an increase of 1.5% compared to last year, due to an increase in organic revenue of 2.6%, partially offset by foreign currency translation of 1.1%. Excluding currency, early development revenue growth was approximately 5%, while centralized revenue growth was approximately 2%. As expected, the central lab's growth rate was low in Q1 2025, as we had a large amount of COVID vaccine and therapeutic revenue in Q1 of 2024. Our segment quarterly book to bill was strong at 1.13, bringing the trailing twelve-month book to bill to 1.07. CLI adjusted operating income for the quarter was $107 million, or 14.8% of revenue, compared to $100 million or 14.1% of revenue last year. Adjusted operating income and margin increased due to organic demand and the LaunchPad savings, partially offset by higher personnel costs. We ended the quarter with a backlog of $8.2 billion, and we expect approximately $2.6 billion of this backlog to convert into revenue over the next twelve months. Now I will discuss our updated 2025 full-year guidance, which assumes foreign exchange rates effective as of 03/31/2025 for the remainder of the year. The enterprise guidance also includes the impact from currently anticipated capital allocation utilizing free cash flow for acquisition, share repurchases, and dividends. We are operating in a dynamic macro environment, and there are a series of regulatory developments that we continue to monitor closely. Our guidance has taken into account various scenarios of the ever-changing tariff and the regulatory landscape. Based on what we believe to be the most likely scenarios at this time, and the resilience of our businesses, we are reaffirming our enterprise revenue and free cash flow guidance while raising the midpoint of adjusted EPS. Enterprise revenue growth guidance remains 6.7% to 8%, compared to 2024. Diagnostics continues to perform well. Consistent with prior guidance, we expect the Diagnostics revenue to be up 6.5% to 7.7%, compared to 2024. We still expect BLS revenue to grow 3% to 5% compared to 2024. This includes the negative impact of 30 basis points from foreign currency. Prior guidance included a negative impact of 140 basis points. We continue to expect enterprise margins to be up, with margins improving in both diagnostic and the BLS in 2025 versus 2024, driven by top-line growth and the LaunchPad savings. Our guidance range for adjusted EPS is $15.70 to $16.40, with an implied growth rate at the midpoint of 10%. As compared to prior guidance, we have narrowed the range and raised the midpoint by $0.05. Our free cash flow guidance range is $1.1 billion to $1.25 billion, unchanged from prior guidance. And due to normal seasonality, we expect it to be weighted towards the second half of the year. In summary, we had a solid first quarter with a dynamic macro environment. We expect to drive continued profitable growth and strong free cash flow generation that will be used for acquisitions that support our strategy and supplement our organic growth, while also returning capital to shareholders through our share repurchase program and dividends. Operator, we will now take questions.
