Thanks, Prahlad, and good morning, everyone. As Prahlad mentioned, we continue to show good performance in the second quarter despite facing new and existing challenges, which were unanticipated at the start of the year. From funding levels for academic research to country and industry-specific tariffs and now new challenges from regulations, which are limiting diagnostics volumes in China, our industry has faced many obstacles so far this year. Considering these developments, we have shown a strong ability to navigate them and respond quickly, allowing us to still deliver strong performance overall as was evident in our second quarter results. I'll start on tariffs. As we first mentioned last quarter, we have quickly taken significant operational actions to largely mitigate their impact, which were executed upon as expected and on time during the second quarter. While some tariffs were rolled back during the quarter, particularly with China, this relief did not meaningfully change their overall impact on us given our mitigation efforts are operational in nature and still moving forward as previously planned. While the tariff situation continues to evolve, as evidenced by yesterday's announced preliminary pack between the U.S. and Europe, our updated outlook assumes the tariffs that are in place as of last Friday, the 25th of July. As it pertains to our updated outlook for the year, we are expecting continued stability from our pharma and biotech customers and the headwinds our academic and government customers are facing to continue. Our assumptions for growth within our Life Sciences segment remain unchanged within our updated outlook and guidance. However, as Prahlad mentioned, since the start of May, we have begun experiencing increasingly larger volume-related headwinds in our immunodiagnostics business in China, which we now expect will continue over at least the remainder of the year. While we were able to mitigate and offset most of the impact from the DRG changes during the second quarter itself, as we move into the second half of the year, we are lowering our expectations for this business in China to account for the trends we are seeing in July, which we anticipate will continue over the coming months. As a result, our immunodiagnostics business in China, which represents approximately 6% of total company revenue, is expected to now be down high teens for the full year. Our updated outlook for this business in China is driving the entirety of the change in our overall outlook for the company. Incorporating the impact of these new pressures, we are now looking for organic growth this year for the total company to be in the range of 2% to 4%, which is slightly below our previous expectations. While this is impacting most diagnostic players in the market, including domestic competitors, we have already begun to take additional near- and longer-term cost actions to help offset the impact to our bottom line. Those actions that are quicker to implement, including rightsizing the business in China, along with other immediate discretionary expense reductions are now factored into our updated outlook. In addition to these near-term actions, we are also taking additional structural actions that given their scope will take into next year to be fully implemented. While we are actively managing and offsetting a significant portion of the bottom line impact, we do expect the drop in volume and some margin rate headwinds from recent changes in FX to have a modest impact on our overall operating margins and adjusted EPS for the year. I will provide additional details on our updated outlook in a moment, but the net impact of this is we now expect our 2025 adjusted earnings per share to be in a range of $4.85 to $4.95, down 1% from our prior outlook. Now turning to the specifics of our second quarter performance. Overall, the company generated revenue of $720 million in the quarter, resulting in 3% organic growth. FX was a 1% tailwind to growth, and we again had no incremental contribution from acquisitions. While FX became more favorable to our top line as the quarter progressed, given the severity of the changes in rates and their geographical dispersion, the change in the top line impact from FX is having a minimal corresponding impact to our adjusted net income, both in the second quarter and in our current outlook for the remainder of the year. As I mentioned, this is generating some pressure on our gross and operating margin rate for the year, given the associated increase in revenue dollars is without a corresponding increase in gross and operating profit dollars. As it relates to our P&L, we generated 26.6% adjusted operating margins in the quarter, which were down 210 basis points year-over-year and in line with our expectations. Our underlying operating margin performance was better than we had anticipated as FX movements were a headwind to our margin rate and the impact from tariffs were in line with our expectations despite the changes that occurred midway through the quarter. Looking below the line, our adjusted net interest and other expenses were $20 million in the quarter, which was modestly impacted by the increased share repurchase activity year-to-date, resulting in lower interest earnings on our cash balances. Our adjusted tax rate was 19.1% in the quarter, which was slightly lower than expected due to the favorable impact of recent tax planning initiatives. We also continue to remain active with our share repurchase program and averaged 117.5 million diluted shares in the quarter, which was down over 2.5 million shares sequentially. This all resulted in our adjusted EPS in the second quarter being $1.18, which was $0.04 above our expectations. Moving beyond the P&L, we generated free cash flow of $115 million in the quarter, resulting in 83% conversion of our adjusted net income. On a year-to-date basis, our $234 million of free cash flow equates to a solid 90% conversion of our adjusted net income. As we move into the back half of the year, I expect our absolute cash flow and its conversion to continue to remain strong and solidly above our 85% long-term expectations. Regarding capital deployment, we have stayed active so far this year with our buyback program as we repurchased $293 million worth of shares in the second quarter. As it relates to our balance sheet, we finished the quarter with a net debt to adjusted EBITDA leverage ratio of 2.6x with 100% of our debt being fixed rate with a weighted average interest rate of 2.6% and a weighted average maturity out another 7 years. As we evaluate capital deployment, we will continue to remain flexible in order to capitalize on the highest return opportunities, while maintaining our investment-grade credit rating. I will now provide some commentary on the second quarter business trends, which is also highlighted in the quarterly slide presentation on our Investor Relations website. The 3% growth in organic revenue in the quarter was comprised of 4% growth in our Life Sciences segment and 2% growth in Diagnostics. Geographically, we grew in the mid-single digits in both the Americas and Europe, while Asia declined in the mid-single digits with China also declining mid-single digits. From a segment perspective, our Life Sciences business generated revenue of $366 million in the quarter. This was up 5% on a reported basis and 4% on an organic basis. From a customer perspective, sales to pharma and biotech customers grew in the mid-single digits, whereas sales in academic and government customers declined in the low single digits in the quarter. Our Life Sciences Solutions business declined in the low single digits in the quarter overall, with declines in instrumentation, partially offset by continued growth in reagents. Our Signal software business was up a little over 30% year-over-year organically in the quarter, and as Prahlad mentioned, had its largest quarter of orders in its history. The business also continued to perform exceptionally well from an ARR, APV and net retention rate perspective as well, with all metrics solidly above levels from last year. In our Diagnostics segment, we generated $354 million of revenue in the quarter, which was up 3% on a reported basis and 2% on an organic basis. From a business perspective, our immunodiagnostics business grew low single digits organically during the quarter, which was in line with our expectations despite China declining more than we expected and being down in the low teens. Excluding China, the other 80% of our immunodiagnostics business continued to perform very well, especially in the Americas, which grew organically in the mid-teens, while immunodiagnostics in Europe grew in the solid mid-single digits. Our reproductive health business grew low single digits organically in the quarter. Newborn screening continued to perform well and grew high single digits globally, which was driven by outstanding operational and commercial execution, given continued headwinds from global growth rates, which have again intensified so far this year, particularly in China. As it pertains to China specifically, overall, we incurred a mid-single-digit organic decline in the second quarter, driven by our Diagnostics business being down in the low double digits as it began to face the impact of the DRG-related declines in volume. This was partially offset by strong mid-single-digit growth in our Life Sciences business in China as we saw improvement in year- over-year growth in both reagents and instruments in the region. Now moving on to guidance. As mentioned, we are updating our organic growth outlook for the back half of the year to account for the new volume-related pressures we are seeing from DRG changes in China and our Diagnostics business. This change is leading to our total company organic growth outlook for the year to now be in the range of 2% to 4%. We continue to expect our Life Sciences segment to grow in the low single digits, unchanged from our prior outlook, but we now expect Diagnostics to also grow in the low single digits, down from our previous mid-single-digit outlook. With the continued weakening of the dollar so far this year, we now anticipate the impact from FX to be an approximately 1% tailwind to revenue for the full year compared to our previous assumption of it being a 50 basis point headwind. As mentioned, given the makeup of the changes in FX, we do not expect it to have a material flow-through in our P&L for the year. We expect these changes to our outlook for organic growth and FX to result in our total revenue this year to now be in the range of $2.84 billion to $2.88 billion overall. Moving down the P&L. We now expect our adjusted operating margins to be in a range of 27.1% to 27.3%, which is down from our prior outlook due to the changes in FX and the impact from lower volume of high-margin diagnostics tests, which is being partially offset by the additional cost actions we are currently implementing. We expect the more significant structural cost actions we are beginning to take to be fully implemented in 2026. We anticipate the impact from these actions will allow us to offset the incremental margin pressures we are now facing this year and to be able to enter next year with a 28% operating margin baseline, which we would then expect to further expand upon commensurate with the level of organic growth we experienced. Consequently, because of these initiatives, we anticipate our overall operating margin expansion next year to be greater than what we would typically be expected in a given year, enabling us to recoup the impact from the new headwinds we are facing this year. Below the operating line, we now expect our net interest and other expense to be around $80 million this year, driven by some incremental pressure from lower interest income. We are continuing to make good progress with our tax planning initiatives and now expect our adjusted tax rate this year to be approximately 18%, down from our prior 19% outlook and the 20% we had assumed at the beginning of the year. With our increased share buyback activity, we now also expect an average diluted share count of approximately 117 million for the year overall. This all results in our adjusted earnings per share for the year expected to be in a range of $4.85 to $4.95. Regarding our outlook for the third quarter, we anticipate organic growth to be in the 0% to 2% range, resulting in total expected revenue in the range of $690 million to $705 million. We anticipate our adjusted operating margins to be approximately 26% in the third quarter, and we are assuming a tax rate of approximately 18%, with roughly 116 million average diluted shares outstanding for the quarter. We expect this to result in our adjusted EPS in the third quarter to be in the range of $1.12 to $1.14. Overall, we performed well in the second quarter despite facing new and existing challenges, which we are actively working to counter and offset. Our levels of innovation and investment remain strong, which when combined with the additional cost actions we are taking positions us well to execute at a high level through all market environments, while always still delivering for our customers. With that, operator, we would now like to open up the call for questions.
