Yes. Thank you, Therese. Good morning, everyone, and a warm welcome from my side as well. Our CEO, Heimo Scheuch, is still recovering from an infection, and therefore, he is not participating today. So yes, let me start with the presentation and jump directly into it. And our first quarter is not a surprise at all. The soft start in the year is fully in line with our expectations, and it was driven by weather-related weakness, especially in January and February. Very important, we saw a clear recovery already in March and volumes picking up and our performance was back to prior year's levels. At the same time, of course, we are operating in an environment of increased geopolitical uncertainty. And of course, that's related to the conflict in Middle East, and that is heavily impacting visibility. Under these circumstances, we reiterate our full year guidance, while, of course, we see that visibility remains limited. But of course, we focus on execution, particularly in integrating Italcer, where we had the closing by the end of April and our disciplined cost and margin management. Now coming to our numbers. Our revenues are down by 7%. That reflects the soft start into the year and as you can see, our volume development, the market was down by 6%. Our operating EBITDA is close to EUR 100 million, which is significant below previous year's levels, but we've already seen a clear recovery in March. And let me just repeat it, it's not a surprise. We expected that. Important is maybe to mention that the first quarter 2025 was a strong quarter, so we compare a soft start in the year with a very strong quarter of previous year. So it's more like a transitional quarter rather than an indicative for the full year performance. Let me now come to the market conditions, starting with Eastern and Central Europe. As you can see, our volumes are significantly impacted by, let me say it again, the severe weather conditions early in the quarter and housing starts remained flat year-on-year. The renovation market was also temporarily affected by the weather conditions and especially in the roof segment. On the other hand, our infrastructure market in that region remained broadly stable. So overall, the region shows a mixed picture with selective recovery. For instance, Poland is a good example where the weak start was mainly weather-related. Underlying demand remains intact. In the Czech Republic, we saw early signs of recovery in permits and starts, but on the other hand, very aggressive competition continues. Austria and Hungary, the demand remains subdued, but of course, with affordability constraints and therefore, it's a mixed picture. Turning now to our region, Europe West. There, again, we see a mixed picture. And of course, volumes overall are down. Housing starts remained at a low level, while the renovation-driven demand was solid in that region. Infrastructure and energy transition supported overall our demand. But of course, the bad weather was the same issue in that region. And to give you a little bit more of a flavor from some countries, Germany was a very soft market in the first quarter and construction activity was still at a very low level, although we are expecting early signs of recovery. In the U.K., the situation continues to deteriorate, and we see declining construction activity and weak consumer confidence. Ireland, on the other hand, is positive. We see public investments on a better level. And yes, Netherlands is showing signs of recovery. And France is still a mixed picture, but we expect an early recovery as well. Belgium, for instance, was quite stable. Overall, the same picture, January and February soft and March far better. Coming now to North America, the North American market, and that was the most impacted region in our first quarter. We see a double-digit volume decline, and that was, of course, driven by the severe winter weather and as well weak new residential activity. The new construction activity remains subdued. Single-family market is stabilizing, but the multifamily market is at multiyear lows. The mortgage rates in North America remain at a high level. On the other hand, our roofing business benefited from a strong backlog and that allowed some more solid production volumes. In the piping business infrastructure, market remains somehow positive, but of course, due to the weather, we've seen there a strong volume decline. And in Canada, the situation is even more challenging. So coming now to some acquisitions. We bought the NEWS Group, and that is an activity with a turnover of around EUR 20 million annually, and we had a closing by the end of April. The NEWS Group that will strengthen our position in water management in the water management segment. It's a very attractive niche for us, and it's a growing market. It's a perfect strategic fit, and it complements our infrastructure and piping portfolio. It's a small transaction, but long term, we see there a big growth potential. Coming now to our recent acquisition, Italcer there as well, we had closing by the end of April. And I just would like to repeat a little bit to finance that acquisition, we don't need a capital increase. We have a strong balance sheet, and we will finance it by ourselves. We have a clear road map, integration, deleveraging, and of course, next year, we have with this call option, the opportunity to get the full ownership. With Italcer, we enter the high-end tiles market. It's strong in the renovation segment. And of course, we see synergies which will rise. And on the other hand, Italcer is active in the facade market, and that will even turn our synergies, which we see on a quite high level. Italcer in total is a company which is at the high-end, has high margins and is a strong multi-brand -- has a strong multi-brand position, not only across Europe but also in North America. Turning now to our numbers. Starting with revenues and EBITDA. Our revenues, as already mentioned, are down by 7%. Operating EBITDA even further, it came in at EUR 97 million. That is far below the previous year's number. But to remember you, the first quarter 2025 was a very strong quarter. The key driver for that, of course, is the reduced volumes we have seen. And here, again, March far better compared with the soft start in the year. Having a look at our revenue and EBITDA bridge, as you can see, of course, volume driven, we have a negative organic growth. So organic growth, our revenues are down by 6%. We lose a little bit on the currency side. And regarding our operating EBITDA, again, you see quite significant negative organic growth. But that's all volume driven and related to the soft start into the year, and that was already expected when we published our outlook. So it's not a surprise at all. We have seen in the first quarter overall a cost inflation of 2%, and that is, again, mainly driven by labor and energy cost. And we don't see in the first quarter more or less any impact of the conflict regarding the Middle East. That will be visible in the second quarter and of course, rest of the year. Our cost inflation with 2% is somehow moderate. And on the energy side, as you know, we have our fixed positions in not only natural gas, but as well, of course, in overall in energy. And there, more or less now 80% of our needed volumes are fixed. Therefore, we are there in a quite good position. We remain to focus on, of course, cost discipline and operational excellence. We are still working on optimizing our production. And of course, we are driving an active margin management to overcome all the pressure we see in the running year. Coming now to our regions, starting with Europe East. Revenues are down by 7%. That is in line with the group development. Operating EBITDA quite weak because it's even below the decrease within the group. There, we had not only the decreased volumes, what we've seen, but we've seen on the cost side, a higher inflation than regarding the group average and the volume decline hit all segments, all markets in the Eastern region, especially the pricing in that region was under pressure. But towards the end of the quarter, we are seeing here recovery as well. Western Europe, our, let me say, most stable region in the first quarter, revenues only down by 3% and operating EBITDA by 14%. As already mentioned, we've seen quite a strong renovation demand and that, of course, supported the performance of that region. Energy transition continues to drive our roof and piping demand. And the weakness was mainly in the beginning of the year from new build and, of course, the severe weather conditions. It's a mixed regional picture, but the most stable development in our first quarter. Coming now to our North America segment, that was the most challenging region because markets have been very soft, very weak and revenues are down by 21%, our operating EBITDA by 37%. As already mentioned, the very soft new build market with weak residential construction is still a topic in North America. And in combination with an ongoing pressure on prices in piping, of course, that's not a nice environment. The U.S. single-family market is stabilizing, but multifamily remains very, very low. And within North America, especially Canada, is more challenging than ever. With that, I'm coming now to our outlook. And just to remind you a little bit on our assumptions for the current year, we are expecting not a structural recovery in residential construction, flat infrastructure and renovation market. And of course, we expect that we cover the inflation, which will increase, of course, during the year due to the Middle East conflict, but price increases. But the Middle East conflict gives us as well a really limited visibility of the total year impact so far. We have mitigation measures already in place, and that's not only price increases. Of course, it's a strict and strong cost management with cost discipline. We have a strong execution. We are ongoing working on working capital management as well as having a focus on our CapEx and spending. And still the Fit For Growth program, which we implemented in autumn last year is, of course, in place and is running. And despite the high volatility and everything, we believe we are well positioned to deliver. And of course, we are supported by our mitigation measures. And with that, I would like to close the presentation, and I'm open to take your questions.
