Thank you, Kevin. Beginning on Slide 9, here we bridge the 4% constant currency revenue decline in the first quarter year-over-year. Starting on the left, LOE was about $60 million for the quarter, which primarily reflects the impact of the loss of exclusivity of Atozet in Europe, which occurred in September 2024. VBP in China was de minimis in the first quarter, and we expect only a nominal impact on a full year basis for 2025. Our potential exposure this year will be more back-half weighted as we expect Fosamax will be included in round 11. Once this occurs, approximately 80% of our Established Brands portfolio will have been subjected to the VBP process. There was an approximate $40 million impact from price for the first quarter, or about 2.5%. Pricing pressure was mainly from biosimilars, certain mature products in the U.S., like NuvaRing and Dulera, and the LOE of Atozet. From a regional perspective, we continue to face expected mandatory pricing revisions in Japan and ongoing competitive price pressures related to our respiratory products in China. Volumes increased $45 million in the quarter, representing growth of a little over 2.5%. Hadlima, Emgality, Vtama, and Nexplanon were the largest contributors to volume growth and will likely continue to be the main drivers for the full year. In supply/other, here we capture the lower-margin contract manufacturing arrangements that we have with Merck, which have been declining since the spin-off as expected. And lastly, foreign-exchange translation had an approximate $45 million impact in the first quarter or about 280 basis points of headwind to revenue, which reflects a strengthening U.S. dollar versus most foreign currencies in the current period relative to the first quarter of 2024. The recent weakening of the U.S. dollar potentially creates a tailwind for us over the remainder of 2025, and I'll revisit this point later in the presentation when we discuss guidance. Now let's turn to Slide 10, where we show key non-GAAP P&L line items and metrics for the quarter. For reference, GAAP financials and reconciliations to the non-GAAP financial measures are included in our press release and the slides in the appendix of this presentation. For gross profit, we are excluding from cost of goods sold, purchase accounting amortization and one-time items, which can be seen in our appendix slides. Adjusted gross margin was 61.7% for the first quarter compared with 62.1% in the first quarter of 2024. The year-over-year decrease in adjusted gross margin primarily reflects the impact of unfavorable price, as I discussed. Non-GAAP SG&A expense was up 6% in the first quarter, driven by commercial and launch expenses for Vtama, which was acquired in the fourth quarter of 2024. Excluding expenses related to Vtama, SG&A was down versus prior year, reflective of our efforts to contain and reduce operating expenses. Non-GAAP R&D expense before $6 million of IPR&D was down 17%, primarily due to the timing of clinical study spend. As we think about the restructuring actions to reduce operating expense that we communicated as part of our 2025 earnings guidance in February, we began executing those plans during the first quarter, and we fully expect to achieve approximately $200 million in expense savings over quarters two through four, which is already incorporated into our earnings guidance. Our first quarter adjusted EBITDA margin of 32% was about 150 basis points better than we expected, in part because of the timing of clinical study spend that I just spoke of. We also did a bit better on gross margin, driven by favorable product mix. Also in the first quarter, we benefited from a $4 million realized transaction gain from foreign exchange, mainly driven by currencies that we can't hedge. Turning to Slide 11, we delivered $146 million of free cash flow before one-time costs in the first quarter, about a third better than the prior year period. This is a function of active cash cycle working capital management, lower interest rates, and timing of cash interest and tax payments. As we said back in February, one-time costs related to the spin-off were completed in 2024 following the rollout of our global ERP system. We expected one-time spin-off costs to be zero in 2025, and you can see that reflected in our first quarter results against $62 million in the prior year period. In the $75 million of other one-time costs, about $15 million relates to cash payments associated with restructuring initiatives aimed at leaning out our operating expense, as I mentioned earlier, $20 million relates to the final payment on the Microspherix settlement, and the remaining $40 million relates to the planned exits from supply arrangements with Merck that, as we've discussed in past quarters, would be ramping up. These are activities that will enable Organon to redefine our appropriate sourcing strategy and move to fit-for-purpose supply chains while focusing on delivering efficiencies in terms of gross margin expansion, which we expect to begin realizing in 2027. Restructuring and manufacturing separation activities could together represent $325 million to $375 million in 2025. Our current view is that we could finish 2025 at the lower end of this range. Once again, these one-time costs drive value that investors will be able to see in 2025 in the form of improved operating expense efficiency and in later years related to more cost-efficient manufacturing that is expected to drive meaningful margin expansion. In 2025, we expect to pay about $200 million in commercial milestones, primarily tied to Vtama, Emgality, in the biosimilar programs with Shanghai Henlius. Through the first quarter, we have paid about $130 million towards that expected amount. The achievement of these milestones means that we are realizing value for business development deals already signed and validates the path to low to mid single-digit revenue growth post 2025 that we've been saying Organon should be able to deliver. Now turning to Slide 12. Our net leverage ratio was 4.3 times at March 31. That performance is consistent with prior commentary that leverage could float up to the mid-4 times area during 2025 as we digest the Dermavant transaction. As we capture more EBITDA benefit from the Vtama launch later in the year and realize the benefit of operating expense restructuring actions, we would naturally delever closer to 4.2 times where we ended 2024. With our revised capital allocation plan announced today that increases our retention ratio, we now have the ability to accelerate progress on deleveraging. In the near term, as Kevin stated, our priority is to reduce net leverage, given the uncertain macroeconomic environment that investors are reacting to. We see a clear path to achieving net leverage below 4 times by year-end. And over time, the capital preserved with a higher retention ratio creates a compounding improvement in financial flexibility. It offers us the opportunity to achieve meaningful deleveraging over the next few years, whether it's through outright debt repayment, accretive M&A, or some combination of the two. Now turning to 2025 guidance on Slide 13. For the operational bars on this page, everything remains the same for the full year. Our constant-currency guidance remains the same, which is about flat versus prior year at the midpoint. We expect the uptake of Vtama, continued solid performance in Emgality, and organic growth in Nexplanon and other products in our portfolio will help to offset the LOE of Atozet in Europe along with pricing headwinds in other parts of the portfolio. That's a pretty strong statement, given that Atozet's LOE represents a headwind of approximately $200 million alone between volume and price. So, with no changes to the ranges on the operational drivers, let's focus for a moment on foreign exchange. The guidance we provided in February was for an expected $200 million negative impact from FX in 2025 or about a 300 basis point headwind. As I mentioned, the Q1 impact was about 280 basis points, in line with that full year estimate. Since February, however, the dollar has weakened. And if current rates persist, we would see some upside to the full year estimate that would move us to the high end of the guidance range. Given the volatility in the currency markets, that upside could be temporary. The responsible thing to do at this point as regards guidance is to avoid chasing a very volatile currency market and for now leave that component of our guidance unchanged and simply note the possibility for favorability over the remainder of the year. We'll be reevaluating our view on FX as the year progresses. From a quarterly phasing perspective, we should deliver modest sequential revenue growth from the first quarter to the second quarter, and we continue to expect the fourth quarter to be the strongest of the year. Turning to Slide 14, where we show all components of our earnings guidance. Again, no changes to what we provided back in February. We expect adjusted gross margin to be in the range of 60% to 61%, about a 1 point lower at the midpoint compared with last year. And that's a continuation of the pressure on gross margin that we saw in 2024, especially in the back half due to price and higher manufacturing and distribution costs. On SG&A expense, we ended 2024 at 25% of revenue, and R&D was about 7% of revenue ex-IPR&D. Those general percentages also hold for 2025. And that guidance implies essentially flat OpEx dollars year-over-year, which is consistent with ongoing actions to improve our operating cost efficiency that would serve as offsets to investments to grow Vtama. Those pieces culminate in an adjusted EBITDA margin range of 31% to 32%. The favorability we saw in Q1 adjusted EBITDA margin was mostly timing. Second quarter adjusted EBITDA margin should look very similar to what Q1 would have looked like without the upside that came through. So, that means we're expecting a Q2 adjusted EBITDA margin in the 30.5% area. We continue to believe Q4 will have the highest margin for the full year as Vtama ramps and we capture more of the benefit of our restructuring initiatives. For below the line items, our estimate for full year 2025 interest expense remains at $510 million, which includes about $25 million related to the debt-like instruments assumed in the Dermavant acquisition. Payments on a portion of those instruments are tied to Vtama sales. Exclusive of the Dermavant transaction, our interest expense estimate for 2025 is approximately $30 million lower compared with last year as a result of the two refinancing events completed in 2024 and lower borrowing rates on our variable rate debt instruments. For 2025, we continue to estimate our non-GAAP tax rate to be in the range of 22.5% to 24.5%. The uptick from 2024 is largely due to the impact of the 15% global minimum tax rate required under the OECD's Pillar Two. Depreciation is a touch higher than last year at $135 million, driven by the completion of our new ERP system in 2024. In summary, first quarter performance was solid and puts us squarely on track to meet our financial guidance for the year. Nexplanon, our largest product, posted another quarter of double-digit revenue growth. Our largest acquisition, Vtama, is launching nicely and is on track to deliver the $150 million in 2025 revenue that we forecasted, and we continue to make steady progress on the $200 million of identified operating expense savings in 2025, which would deliver our best operating expense efficiency metrics since the spin-off. We expect these OpEx savings to benefit not only 2025, but annualized to roughly $275 million, which we would realize in 2026 and thereafter. And finally, the change we are making to our capital allocation priorities to increase our retention ratio will enable us to accelerate meaningful strengthening of our balance sheet, including lowering our 2025 net leverage ratio target to sub-4 times by the end of the year. With that, now let's turn the call over to Q&A.
