Thank you, Helen, and welcome to everyone on the call also from my side. I will pick up on Slide 7. In the first quarter, we achieved solid organic revenue growth of 4%, supported by growth in all 3 operating segments. At constant currency, revenue increased by 3%. Care Enablement revenue development continues to face headwinds from regulatory pressure in China. Divestitures negatively impacted revenue development by 50 basis points. We delivered strong operating income growth of 10% at constant currency. This increase was supported by contributions from all operating segments and is in line with our expected phasing for our '26 outlook. Special items in the first quarter amounted to a net negative EUR 181 million, mainly reflecting costs associated with FME25+ as we accelerated our U.S. clinic closures. In line with expectations, FME25+ costs are planned to come down over the course of the year as costs related to U.S. clinic closures are first half loaded. Turning to Slide 8. This chart illustrates the year-over-year improvement of the group operating income margin, highlighting a further increase of 70 basis points. With 10.1%, this is a solid start toward achieving our projected group operating income margin of 10.5% to 12% for the full year. Care Delivery was the main driver of improved profitability with a small contribution from value-based care. The higher intersegment elimination reflects the 5008X CAREsystem sales in the United States. Corporate costs increased by EUR 37 million. This was mainly driven by the planned cost of strategic IT platform investments, including preparation for the transition to SAP S/4HANA. FX translation effects were unfavorable this quarter and stood at negative EUR 34 million. The average U.S. dollar exchange rate in the first quarter was $1.17 compared to $1.16 in the fourth quarter and compared to $1.05 in the first quarter of 2025. I will now walk you briefly through the business development in each segment, starting with Care Delivery on Slide 9. Care Delivery achieved organic revenue growth of 6%, driven by both Care Delivery U.S. despite muted U.S. volumes and Care Delivery International. At constant currency, revenue increased by 5%. In the U.S., growth was driven by a positive impact from the TDAPA reimbursement regulations as well as favorable rate and payer mix effects. Our U.S. payer mix remained strong in the quarter with relatively low attrition in the exchange patient population. We expect that attrition to increase over the course of 2026 as rate periods expire and affordability pressures grow around higher premium and out-of-pocket costs. We continue to expect an impact of around EUR 50 million for full year 2026. The impact from divestitures as part of our portfolio optimization plan reduced revenue growth by about 80 basis points. The main driver here was the prior year divestment of our clinics in Brazil. Care Delivery realized strong operating income growth of 26%. This resulted in a margin improvement to 12.1%. Benefits from TDAPA reimbursement regulation for phosphate binders and catheter lock solutions were, as expected, a meaningful driver of the earnings development. We continue to assume a significant headwind from TDAPA reimbursement regulation in the second half of the year. Importantly, excluding TDAPA benefit, the underlying business realized around 6% earnings growth on a constant currency basis. This includes favorable rate and mix effects, lower implicit price concession, thanks to our revenue cycle management initiatives and partially offset planned strategic investments for the 5008X rollout in our U.S. clinics. Savings from the FME25+ program contributed positively. The anticipated labor cost increase as well as currency translation effects had a negative impact in the development. Turning to Value-Based Care on Slide 10. Value-Based Care realized 3% revenue growth on both an organic and constant currency basis. This was driven by a higher number of member months from contract expansion and positive effects from premium rates. Prior period contract true-ups also created positive growth in the first quarter. This was partially offset by the change of risk type for a large contract resulting in a different accounting treatment and lower revenue recognition. We expect revenue growth will turn negative throughout the year, primarily due to the change in accounting treatment. Operating income for Value-Based Care increased significantly in relative terms and the margin was enhanced by 100 basis points. Value-Based Care was profitable for the second consecutive quarter. The increase in business growth was mainly driven by an enhanced savings rate. FME25+ program-related savings resulted from the reorganization of the team to take advantage of integration with Fresenius Medical Care and becoming more efficient while aligning staffing with our strategic priorities. Higher inflation and currency translation effects were offsetting factors. I will turn to Care Enablement on Slide 11. Revenue in Care Enablement increased by 1% on an organic and constant currency basis. Organic revenue development reflects continued positive volumes and pricing, excluding adverse regulatory impacts in China, which include volume-based procurement and switcher tender requirements. Revenue was also supported by strong sales of the 5008X CAREsystems in the United States. Care Enablement earnings slightly increased on a constant currency basis, leading to a 40 basis point margin improvement. Business growth was impacted by adverse regulatory impacts in China and negative currency translation effects. Positive volume and price effect outside of China contributed positively to business growth. Additional, FME25+ savings from continued progress in manufacturing and supply chain initiatives supported margin expansion. Inflationary costs increased and had a negative effect. Next, I will look at the cash flow growth on Slide 12. As always in the first quarter, we have a seasonality effect in invoicing, which is why the quarter typically represents a relatively low share of the full year operating cash flow. This year, while on the typically lower quarter 1 level, we realized a strong increase in operating cash flow by 39%. The main driver was favorable working capital management. Free cash flow increased by 94% to EUR 40 million. Total debt and lease liabilities as well as total net debt and lease liabilities were broadly stable compared to the prior year period. As part of our share buyback program, we repurchased a total of 23.3 million shares for EUR 941 million by the end of the first quarter. This represents 7.9% of share capital. On April 30, we successfully completed our initial share buyback program of EUR 1 billion. We bought back in an accelerated way, 24.8 million shares or 8.5% of share capital. With 2.6x, our net leverage ratio continued to be around the lower end of our self-imposed target corridor of 2.5 to 3x. I will now hand back to Helen.
