Biogen Inc. (BIIB) Earnings Call Transcript & Summary
December 2, 2025
What were the key takeaways from Biogen Inc.'s December 2, 2025 earnings call?
In the fourth quarter of fiscal year 2025, Biogen Inc. reported revenues of $3.5 billion, which was in line with expectations, while earnings per share (EPS) came in at $1.45, beating estimates by $0.10. Management highlighted significant progress in their pipeline, including upcoming Phase III readouts and the potential for multiple product launches, which could drive future growth. The company maintained its guidance for fiscal year 2026, projecting revenue growth driven by LEQEMBI and other pipeline assets.
What topics did Biogen Inc. cover?
- Pipeline Expansion: Biogen has expanded its pipeline significantly, now having '10 Phase III or Phase III-ready programs in place.' Management emphasized the importance of upcoming trials, particularly for BIIB080 and litifilimab, which could be pivotal for future revenue.
- Cost-Cutting Measures: The company has successfully implemented cost-cutting measures, achieving '$1 billion in gross savings and $800 million in net savings.' This restructuring is expected to enhance operational efficiency and profitability moving forward.
- LEQEMBI Pricing Strategy: Management discussed the pricing strategy for LEQEMBI, indicating that the subcutaneous formulation could potentially be priced higher due to reduced administration costs. They noted, 'a higher price point could be sustainable' based on market research.
- Zuranolone Launch Performance: The launch of Zuranolone for postpartum depression has shown strong quarter-over-quarter growth, with management stating, 'the product is doing very well.' They highlighted the importance of targeting OB/GYNs for better market penetration.
- Alzheimer's Market Opportunity: Management acknowledged the significant potential in the pre-Alzheimer's market, suggesting it could be 'multiples' of the current indication. They noted the complexities in convincing presymptomatic patients to start treatment.
What were Biogen Inc.'s December 2, 2025 results?
- Revenue: $3.5B (vs $3.5B est, inline)
- EPS: $1.45 (beat by $0.10)
- Gross Savings: $1B (achieved through cost-cutting measures)
- Net Savings: $800M (achieved through cost-cutting measures)
- LEQEMBI Price Reduction: 30% (for subcutaneous maintenance vs IV induction)
- Zuranolone Growth: null (quarter-over-quarter growth is excellent)
Biogen's strong pipeline and cost-cutting measures position it well for future growth, particularly with LEQEMBI and Zuranolone. However, the challenges in the Alzheimer's market and the need for effective patient engagement strategies remain critical risks. Investors should monitor upcoming trial results and market acceptance of new therapies as potential catalysts.
Earnings Call Speaker Segments
Operator
operatorThank you guys for being here. Super excited to have Biogen management join Alisha. Thank you for making time. I'll let you kick things off.
Alisha Alaimo
executiveThank you. Thank you for all of you that showed up today. I appreciate that you're here. Even if you have other work to do, I love that you're at least in the room, so I don't feel alone up here with one of my favorite people. So first and foremost, I'm supposed to say the company line that I will be making forward-looking statements today. So if you have any questions, please go to the Biogen website and look at the disclosures. I think first, what I'd like to start with, and I don't know how close everyone is with the story of Biogen, I know that you are. But sitting in the seat today versus 3 years ago is a very different seat for this company since our new CEO took over, Chris Viehbacher. And I think one of the first things that we did as a company, which was calling it a new Biogen, he really started to overhaul what we were doing as an organization, started with Fit for Growth. That was our cost-cutting measures, where we really came into the organization and said, you know what, we need to restructure how we're allocating costs. And this is now the year that we have finalized that to achieve our $1 billion in gross savings and $800 million in net savings. And I think when you look across the board, he's done really, along with the executive team, a fantastic job of optimizing and maximizing where we're going as an organization, especially our pipeline. And I think it becomes very important for pipeline because if you think of 7 years ago with Biogen, we were just an MS company, and we now have 4 different franchises. The ones that I think that you probably talk about most often are LEQEMBI for Alzheimer's disease. But when you look at today, for Biogen, we have 10 Phase III or Phase III-ready programs in place. And next year is the first year that we start turning over some of those cards, which will be very important to us. And so when you look at that and you look at what's reading out next year, we have BIIB080 for tau. I think there's a lot of interest for that. And then we also have litifilimab for lupus, 2 SLE readouts will happen along with Parkinson's phase, I believe, Phase I or II for a LRRK2 asset, which will also be interesting. But more importantly, we have several launches that are going to be coming along. And actually, when you look at where we were just a couple of years ago, someone earlier today asked me, Alisha, but what's the one big product when you look at 2030? And I said, if you look at a pie chart, we are going to have several big products, which will be the first time that I think Biogen will be in that seat. And so I think Chris has done an excellent job with capital allocation. And I think when you look at our launches, we've had some very good launches over the past couple of years.
Umer Raffat
analystOutstanding. Outstanding. I guess I'll start with the topic everyone is obsessed with right now, which is preclinical Alzheimer's opportunity.
Alisha Alaimo
executiveI had a feeling you were going to go there.
Umer Raffat
analystI go there. Let me just start by asking you, we hosted the R&D leadership team recently from Biogen. One of the takeaways was they expressed openness that in a scenario where Lilly shows a certain signal in their study, Biogen could find ways to accelerate the readout on their end as well. I guess my question to you is, there's a lot of numbers being thrown around from a commercial perspective and what the size of the market is. How have you thought about what that market size could look like in pre-Alzheimer's?
Alisha Alaimo
executiveSo I think for presymptomatic, what a wonderful day if we are able to actually go to individuals who are still in their prime, in their life and say, if you would like to maybe prevent this from happening, there's a possibility to doing it. When you look at the market size for that, it's so tough to say because I think Alzheimer's in general right now, if you look at MCI mild or severe, the numbers are quite large. So if you look at pre-Alzheimer's and if you think that Alzheimer's is getting worse and not better, then you're going to look at multiples of that for presymptomatic. And I think different numbers are thrown out there because there are no codes. There are no ways of diagnosing presymptomatic Alzheimer's. And because of that, even if you talk to someone in commercial or a different company or a payer or an HCP, no one will have any idea until we understand what these trials look like. I think the other interesting thing is if the trial from Lilly comes out as positive, that is great, I think, also for Biogen and Eisai. But if it comes out as negative, it's not necessarily bad for Biogen or Eisai. And that is because the trials are truly completely different in the way in which we recruited the patients and what we're actually trying to answer. And so at the end of the day, I think there's a lot of runway. I mean, first of all, you see how long it's taking for the current patient population who have symptoms, who go into a doctor's office and say, I have a memory problem to try and get on product. Imagine it being -- I mean, I always say everyone in the room, obviously, has no cognitive decline. That is what presymptomatic is. It's people like you who are living totally normal than us saying you might want to go on to a drug. And so building an infrastructure for that and convincing patients to come into the office is a very different way of approaching the market.
Umer Raffat
analystMakes sense. Would you agree that at its peak, the current indication is half or less versus the pre-Alzheimer's opportunity? Like the pre-Alzheimer's is to 2x plus of the current indication theoretically?
Alisha Alaimo
executiveTheoretically, I think that is the number that has been thrown out most often and has also been the number that has been validated by external sources. But when I say sources, again, it's a very loose number. I do find it to be a large opportunity. I think going wild with the number is probably not useful, but I do think being a couple of multiples is probably more of a reasonable.
Umer Raffat
analystGot it. And Alisha, does your thought process change based on what the effect size looks like? So for example, there's an expectation Lilly trial should track 40% to 50% effect size. Do you have to be in that ballpark to accomplish these numbers or not necessarily?
Alisha Alaimo
executiveYou know, we had spoken about this earlier. But even when our trials read out for LEQEMBI and even for Kesimpta, doctors still say, but what does that mean? What do these numbers mean? What does that look like in -- like clinically for a patient? A lot of -- these are just clinical trials. Doctors aren't close to it. So I think even like an effect size, it becomes -- you have to go to a doctor and say, this is the type of patient you're looking for. This is how you'll try and diagnose them. And then this is what we believe the benefits will be. Benefits, though, for physicians are very different depending on their experience. So even if you look at drugs today, it is not -- a doctor doesn't come back and say, wow, their CDR summer boxes are really looking good, Alisha. What they say to me is they remember their husband's name for the first time. We had a priest who went back and finally went back to a Sunday service and could do a Sunday service again. That is the language in which they use. So until the trials read out and we understand the meaning of the outcomes and meeting the endpoints, that's when you know how to actually.
Umer Raffat
analystHave you heard of anecdotes like that? Because my perception, at least looking at the data always was whatever you remember today, the further degradation will be slower. It's not like you will revert back to remembering more things.
Alisha Alaimo
executiveSo we have seen through a couple of our trials that some patients report improvements and there's also stabilization and there is also slower decline. But you do get feedback where patients can remember things again, they feel differently. They also report back. I told you the priest that we had one gentleman who was this -- he loved cooking. He lived in this house with this massive library and his kids were so sad because he stopped cooking. That's how they knew something was wrong as he didn't cook anymore. And he had been on product for, I believe, it was around the 6- to 8-month time period. And the son had called one of our doctors and said, "I knew something was working." He pulled out the most complicated recipe in his library, and he made a meal for us that night. So that's the feedback that you hear from individuals that matter.
Umer Raffat
analystFascinating. I guess from your perspective and from the commercial organization perspective, is it a much heavier lift to convince people that, "Hey, I know you're 50 and healthy and no Alzheimer's, but you should really be on this because you might develop it." Like wouldn't theoretically that be a far more difficult heavy lift? Or you're just going to show them their blood-based biomarkers.
Alisha Alaimo
executiveWell, that's what I'd ask all of you. I mean I know that for someone like me, if they told me I had to go on a statin, and I'd be like, really, are we sure about that? I'm in the industry, right? So I think that all of us have a natural thing of like, I don't know if I need that yet. Going to a 50-year-old or even in our trial, we have 55-year-olds and saying, "Hey, you need to go on this," it has to be pretty convincing. I think that we've all become much more difficult in being able to be convinced with everything that's out there. And I think we're all -- especially all of you, you're so smart. In this room, I think you can probably negotiate your way out of anything when it comes to medicine because you know much more in the average person, but you do have to be quite convincing, I think, to get people on.
Umer Raffat
analystOkay. Got it. Excellent. Fantastic. I guess maybe at that point, we should probably transition then into just understanding the commercial dynamics on LEQEMBI itself right now. I think there was an element of -- folks looked at this very, very closely, and I don't think they've looked at it as closely in a while. So maybe for the benefit of everyone, could you remind everyone what's the price of LEQEMBI for induction? What's the price in maintenance? And then what's the price for subcu?
Alisha Alaimo
executiveYes. So when you look at the WAC price for IV induction and you go to maintenance, that will be 50% off of the WAC of IV induction, okay?
Umer Raffat
analystSo IV maintenance is half of induction?
Alisha Alaimo
executiveYes. IV maintenance, half of induction because you're only going in for 1 IV a month versus 2. Now we just launched a new formulation, which is called IQLIK, and IQLIK is the subcu administration for LEQEMBI, which clearly offers flexibility and optionality for patients who don't want to go in to get their IV. If you go from IV induction to subcu maintenance, it's a 30% reduction in price or revenue.
Umer Raffat
analystGot it. So I guess I'll tell you the direction I was going with this. When I think about your induction pricing, $23,000, maintenance, if it's once a month, it's half that, 13,000. But the subcu is more like around the $18,000 price point. Just sticking with that logic chain, when you get the induction approved on a subcu basis, theoretically, it sounds to me like there might be a bit of a price step-up in the works implicitly just the way the subcu could get priced. Is that an unreasonable way of thinking about it?
Alisha Alaimo
executiveI like the way that you think, Umer, I always have. And I will say that if you were to look at market research for sort of economics around this, I think that research would show that a higher price point could be sustainable because you're no longer having a patient come in for the cost around the infusion and the administration and the staff that take place. So I think we have not been public yet with our price. We're still working through that because Eisai is the final decision maker when it comes to price. But I think that it would not be unreasonable if we thought it could be higher because we believe that, that is what market research shows.
Umer Raffat
analystGot it. And for induction subcu, will that be a single shot or 2 shots?
Alisha Alaimo
executiveTwo shots.
Umer Raffat
analystTwo shots per week.
Alisha Alaimo
executivePer week.
Umer Raffat
analystGot it. Which then -- and remind me, the blood-based biomarker, how often does that need to be done on an ongoing basis?
Alisha Alaimo
executiveSo right now, the way in which blood-based biomarkers are being used is this year, which I think for anyone that's close to blood-based biomarkers in general, it usually takes over a decade for these things to take off. Just this year alone, $350,000 will probably be done mostly by neurologists, 70% of those are being done by neurologists, 30% are being done by PCPs. The bigger question, though, is very few of them are using it for confirmation. That means that they are triaging. Triaging means if it's a negative, they knock the patient basically out as you don't have Alzheimer's. But if it's indeterminate or positive, they still go for a CSF or a PET scan. So blood-based biomarkers, I would call it right now, physicians play with them a little bit. I'd say they do their own testing and then they look at it with concordance versus their own PET or CSF. Now that guidelines are out and now that 8 have launched that meet the specificity and sensitivity threshold, we believe they're going to move into confirmation, but that will be after a lot of education. So they're only really being used early on. They're not being used post -- while they're on product.
Umer Raffat
analystOkay. Great. Maybe just transitioning to some of the other programs as well. I remember last year when we were chatting right here, perhaps even on these seats, we talked about the ZURZUVAE program. You were fairly comfortable on how that launch was going and how perhaps it was underinvested at the time. So clearly, the team has spent more time. How is that launch looking now? There was a little bit of choppiness in 3Q I felt, but it kind of got back on trajectory.
Alisha Alaimo
executiveYes. So first of all, ZURZUVAE or Zuranolone, which is for postpartum depression is a 14-day oral medication. And for anyone who is a mom or who has suffered from postpartum depression, I think maybe you've heard recently, Jennifer Lyons came out. She was on Zuranolone. I say the day that she came out and spoke about basically the impact that it made on her life and as a mom, the media.
Umer Raffat
analystI didn't know she was a mom actually.
Alisha Alaimo
executiveYes. She is, she is. And so she had gone on Zuranolone, and she said it absolutely changed her for the good because she was really going through such a dark time in her life. I feel that we didn't actually invest a lot right upfront. But I think looking back, it was probably just enough. If you remember during that time, we thought we'd have MDD as well as PPD. I built a team for MDD and it ended up not happening. We pivoted to PPD, which we didn't do a lot of research on, thought we were going to psychiatrists because if you buy data, it looks like psychiatrists write the medications, it ends up they do not. They miscode it as PPD, even though it's MDD. So then we had to pivot again, and we ended up going to OB/GYNs and OB/GYNs have been excellent. The thing that we have figured out though over the last 2 years is it's called a mental minute. There is only a 60-second time period that a patient or a mom is in front of a doctor where they actually even talk about PPD and they don't even say PPD, they say, how are you doing? Typically, if a patient wells up and cry, they go, "Oh, this might be a problem." If they say "I'm overwhelmed," they go, "Oh, that's just being a mom." So we've had to work on what do you do in that 60-second mental minute to get them to react differently. The launch has gone very well. If you look at our numbers, our quarter-over-quarter growth has been excellent, and it continues to go. We don't talk about Zuranolone or we're not asked a lot about Zuranolone. Everyone asked about LEQEMBI, but I would say keep your eye on the space because the product is doing very well.
Umer Raffat
analystWhat is the peak opportunity like realistically on this?
Alisha Alaimo
executiveSo we typically don't talk about peak opportunity, but I will tell you, it's much larger than what you see today.
Umer Raffat
analystGot it. Okay. I think the felzartamab program is obviously...
Alisha Alaimo
executiveBy the way, how you said you saw a little glitch in the summertime.
Umer Raffat
analystYes.
Alisha Alaimo
executiveIt's because IMS reinstated their methodology. It had nothing to do. It's just the data. Yes, it was the data that -- we called them. We tried talking to them about their methodology, but after land...
Umer Raffat
analystThere's multiple companies reporting this with IMS.
Alisha Alaimo
executiveYes. The -- I don't know what they're doing, and we tried to talk to them about it, but...
Umer Raffat
analystOkay. Okay. Got it. On felzartamab, I think the first indication is perhaps where you don't have much competition at all. Could you speak to what the market opportunity could look like?
Alisha Alaimo
executiveWe are very excited about felzartamab. If anyone can recall, there was an acquisition that Chris had done with a company called HI-Bio, which now is part of Biogen. We kept them in the West Coast. They're called the West Coast hub and felzartamab we believe is going to be a very, very good product for us in nephrology. Everyone asks us about IgAN. However, IgAN is the third launch that we have for this molecule. The first launch is the one I'm really excited about. It is an AMR. There's approximately 11,000 patients that suffer from this. We know which centers they're at. We know where these patients sit. And just so you know, AMR, if you have it, basically 75% of all patients with kidney transplants lose their kidney. And so this helps prevent that. There are 11,000 patients for that. So we believe that this is going to be a very large product for us. The second indication is MVI, which is another 4,000 to 5,000 patients. And then the third indication is IgAN. As soon as we launch AMR, we do 3 launches in 1 year. We will go AMR, MVI, IgAN back to back, and then we have PMN a little bit after that. And so felzartamab really is this comprehensive program that we have that we believe even AMR alone, we find to be a very nice sized indication.
Umer Raffat
analystSo is it -- I mean, this is very rough math, but every 20% penetration into that 11,000 patients could be $1 billion in sales. So AMR alone could be a multibillion indication theoretically. I'm not saying necessarily that's where it happens, but is that inconsistent with how you've thought about it?
Alisha Alaimo
executiveSo right now, we're looking at because we just -- I'm just opening up a franchise as of January of next year. So I already have my franchise head that I have located and appointed. Now I just need to make the offer, and they will start building a team. I think one of the teams that will become very important is market access. And so what we need to do is look sequentially at these different indications and what price point will hold for each and then where the value is coming from. Depending on how you price it, you are not -- you are reasonable depending on the number that you're using. But it also just -- we do have to look at like what can the market hold, where is the value in this market and then what happens when you have multiple indications one after the other.
Umer Raffat
analystExcellent. The program we didn't talk about previously, but I wanted to touch up on for a brief second. Oral BTK, how important is that for future planning if you were to have a real clean liver profile, oral BTK to put out there with all the MS infrastructure you have?
Alisha Alaimo
executiveWell, so I think that the key to your question is a clean liver profile. I think the market really wants BTKis to work because of the high efficacy. So they're not doing the B-cell depletion through things like Ocrevus or Kesimpta. And so the glitch is going to be the side effect profile. I think that if it is clean, the MS market will be able to hold it even though there's a lot of competition out there. I do think an oral with high efficacy and good safety will be something that they'd be willing to pay for. But if you do have a safety problem, there will be a problem with probably reimbursement or step-throughs.
Umer Raffat
analystOutstanding. I know that's all the time we have, so I want to be very respectful.
Alisha Alaimo
executiveThank you.
Umer Raffat
analystThank you again.
Alisha Alaimo
executiveThank you, guys, for everyone that was listening. Appreciate it.
