Thanks, Severin. Hello, everyone. Great to have a chance to talk about our results so far this year. So starting out with the revenues and the global picture, as Severin mentioned, we grew pharma sales 6% year-over-year in the -- around the world. And the parts breakdown as follows, United States, we had 2% growth. So good to see another quarter sales growth in the U.S. and that was driven by a number of things. But basically, the pipeline offsetting or more than offsetting the biosimilar impact. In Europe, we were minus 1%. That was affected by the COVID sales. So for example, without Ronapreve, that, you'd add about 5 percentage points to that year-over-year because we had higher sales of Ronapreve last year than this year. So good healthy demand in the core portfolio. Japan, very strong growth based on a number of factors, but in particular, a large government order for Ronapreve in Japan. And then international markets. We had growth in our pipeline, our new launches across the world, offset by biosimilar impact, primarily in China. China was down about 9% based on AH&R biosimilar impact. If you look at it from a product standpoint, again, you can see Ronapreve at the top with the large yellow bar. This is the Japanese government order. The total sales were approximately CHF 600 million for the quarter. And as we mentioned before, we think that the total sales for Ronapreve this year will be around CHF 1.6 billion. So a good chunk of it happened in Q1, and we believe the great majority of it will actually happen in the second half. So there should be lower Ronapreve sales in Q2. And then you can see the -- again, the newly launched products driving the bulk of growth. If you look down at the bottom, you see the impact of biosimilars, which was somewhat less about CHF 580 million in Q1, a bit lower run rate than we've had partly because of the general slowdown and the impact of biosimilars, but also because of sort of ordering patterns in the U.S. So we still think that the overall impact of biosimilars this year will be around CHF 2.5 billion. So in oncology, just a couple of things to point out. So we actually grew the HER2 franchise again, which is a new thing because in recent quarters, it's been affected quite significantly by the Herceptin biosimilar losses, whereas now with continued growth, particularly with Kadcyla and Phesgo; Phesgo is the fixed-dose combination of Perjeta and Herceptin. We were able to move into growth territory and hope to will continue that for some time. Also, I'd point out on here, a couple of things about hematology. So in Polivy, we had an 89% growth, which we think is sort of some early potential use in the first-line setting sort of experimental use. But I think it's also now going to be reinforced by the approvals. We have the positive CHMP opinion for DLBCL now for POLARIX in EMA, and we look forward to additional approvals in China and the U.S. later this year. Also in hematology, I wanted to point out that we received a positive opinion for mosun and from the CHMP. We just received that on Friday. So we're really excited to bring a new molecule, another new molecule to the world and this time, starting with EMA and starting with Europe. Going a little deeper on Phesgo. So this is the fixed dose combination I mentioned. And basically, this is a subcutaneous formulation that's given with the device, and it basically cuts the overall administration and monitoring time for patients from between 2 and 8 hours down to 20 to 40 minutes. And as you can imagine, that's a very popular option for patients, but also for many health care facilities that have limited capacity. This is a great way to help patients come in and get out, and this has been a really popular option, and we think that the growth is going to continue for some time. Now let's talk about Tecentriq. So as you can see, the curve here is looking a little flat, and I want to explain that. There's a couple of factors that are most important in driving this. One is that, as you know, we withdrew voluntarily the labels for bladder cancer and TNBC. And so from a year-over-year basis, that's certainly an effect, but also that's basically washed out now. We think that there are very few patients left on Tecentriq with bladder cancer or TNBC. So actually, if you look at the U.S., we had a quarter-over-quarter gain in Q1 as we see that washing out and starting to build momentum with the adjuvant lung cancer launch. In Japan, it was the other major factor. They had a significant price cut in Japan that was mandated because of the rapid expansion. They've reached a threshold where the government required a price cut. And so that's baked in there. We've also now achieved pretty high penetration with the small cell lung cancer indication. And so further growth with Tecentriq is basically going to come from additional penetration in liver cancer as well as launches that are now happening around the world in adjuvant lung cancer. Now in the U.S., we had really, I think, encouraging results. We just received the approval in Q4 in the adjuvant setting. And in the Q1 tracker, we had 72% testing rate for adjuvant patients. So 70% -- 72% of the patients that are getting adjuvant therapy are eligible, are getting tested for PD-L1 positivity. So that's sort of a first step. And then we have 49% penetration in that patient set with Tecentriq. So really, I think, a strong signal of early uptake and we should see the revenues proceeding from that in the quarters ahead. And also proceeding from Europe and countries around the world as we launch. Hemophilia, I think a very strong picture for Hemlibra. If you look at the chart here, starting with the U.S., you can see continued growth of Hemlibra, and we believe we don't see a flattening of the U.S. growth. I mean we think we're going to continue to grow in the U.S. for some time, even though we're above 30% patient share now. Likewise, in Europe, we had nice growth, international markets continuing to gain a bit. And then in Japan, the quarter-over-quarter result was down a bit, but we believe that's basically on ordering pattern where the wholesalers sort of did stocking at the end of the year. So we're not particularly concerned about that, and we see continued growth through this year and beyond for Hemlibra. Immunology is more or less stable, minus 2% year-over-year, with gains from Actemra offsetting losses from Rituxan. The Rituxan immunology indications that have been impacted by biosimilars. And basically, we think this will potentially continue to climb a bit. As COVID wanes, we should see Actemra sales for COVID waning as well. MS franchise, I think a really strong quarter. You can see nice gains in the U.S., in Europe and international markets. So 18% year-over-year growth overall, some really strong momentum. And this is in the context of a continued impact of COVID on switching. So we've had the Omicron wave in the U.S. and Europe that hit quite hard in the U.S., particularly in December and January and in Europe through -- even through March. And so this has affected the switching of patients but despite that, we continue to see strong gains, and we look forward to sort of getting beyond the pandemic so that we have maybe a return to a more normal switching rate and accrue more patients for OCREVUS. Turning now to Evrysdi and SMA, I think, a pretty good picture. In the U.S., as we reported in Q4, there was a small decrease year-over-year -- or sorry, quarter-over-quarter in sales. And we speculated that this was due to sort of a bolus of patients who had come on, especially older patients who had come on and sort of we're trying it and testing it and some of them dropping off, what we had a return to growth in the U.S. in Q1, and we see that continuing strong growth in Europe as well. And then in international and Japan, this is a little lumpy right now but we see good dynamics overall and look forward to continued growth of Evrysdi. This is one of the reasons we're quite optimistic. So this is data that we've shared at the MDA clinical conference. And this is basically on the presymptomatic babies, so babies under 2 months of age. And we've now filed this data to extend our indication back earlier to these presymptomatic babies. But essentially, what it showed was very strong results on the things that matter, things like sitting without support, being able to crawl, being able to stand unaided and walking. And so we're really encouraged that we see these patients essentially achieving maximum scores in most cases, which means that they are on a very similar curve to normal babies, babies who don't have the mutations that cause SMA. So really good news for these patients and their families and for Evrysdi. Turning to ophthalmology. I think another really set of good news. So this is the data in DME on 2-year data. So previously, we had shown the 1-year data, which is shown on the left in the pie charts. And importantly here, this is a measure of what proportion of the patients were able to extend dosing beyond the monthly dosing, which is where they start. And what you can see is at 52 weeks, approximately 50% of patients were able to go to Q16 week dosing, so approximately 3 times a year. And this is really unprecedented in the history of treatment for DME. And so we were anxious to see would that advantage be maintained at 2 years. And essentially, what we've seen is really encouraging that actually the percent of patients who can benefit from dosing is seldom as 3 times a year, actually increased from about 50% up to just over 60% on average. So again, the folks that we've shared this data with and we were able to present it at the big Angiogenesis meeting in February, they were ecstatic about what this means for their patients. And so now Vabysmo has launched in the U.S. It's going to be -- it's approved in Japan. We'll be launching soon with reimbursement and coming to Europe and other countries later this year. So really exciting times. We've seen a very strong uptake. We have initially about CHF 21 million of commercial sales, but also a high amount of interest in samples. And so again, we see this really getting momentum. We've also had a lot of reports back from physicians who've said patients who were on other therapies, and they weren't able to get dry, that once they gave them Vabysmo, they saw them drying in as soon as a month, which is really important and really impressive news for us. And we've also got now 11 paid claims in the U.S. which basically means different plans, making their first paid claim which is really important because that gives physicians confidence that they can prescribe Vabysmo and be reimbursed. And so while we'll be getting a permanent J code in probably end of Q3, early Q4, this kind of news gives doctors reassurance now, and we believe we'll see continued strong uptake of Vabysmo. This is data that we also shared on Susvimo, which is our long-acting implant device and basically shared that 2-year results looked very similar to 1 year results. And again, it's just an additional boost for our ophthalmology portfolio. Now I want to finish with the key news flow from the late stage. So as I mentioned, Vabysmo has now been approved in the U.S. and coming soon in Japan and Europe. Glofit, which is one of our T cell biospecific antibodies. We now have the Phase III data in third line, the pivotal data in-house. And this data -- sorry, I said Phase III, it's the pivotal Phase Ib. This data has been filed in Europe and will be filed in other jurisdictions soon. So we'll be sharing that data at ASCO and look forward to presenting that. We did mention last quarter that the small cell lung cancer study for tiragolumab had failed, so we were sorry to see that. There's only been basically 1 breakthrough for small cell lung cancer in the last 30 years, and that was Tecentriq's first Phase III study in small cell lung cancer, but it looks like we're going to have to wait for some other developments for the small cell lung cancer patients. But we remain very confident in our Phase II data in non-small cell lung cancer and look forward to a readout of the SKY 01 program in Q2 and an ability to share that data with all of you and the scientific community coming soon. We also mentioned in the press release, I'm sure you've read that our Phase II study in late-line ER-positive breast cancer with giredestrant was negative. While we missed on the primary endpoint, we saw an encouraging signal that gives us, I'd say, continues to bolster our confidence in both the first line and the adjuvant setting, and we can talk about that more in Q&A, if you'd like. And then finally, I wanted to mention that with the Alecensa program, that we think that we will go to the final analysis in 2023 on the adjuvant program. So this has to do with event rates, and the event rates were lower than we had projected. So hopefully, that's good news, but it means we'll have to wait a little longer for the answer. And with that, I want to hand it over to Thomas.
