Thank you, Kevin. Good morning, everyone, and thank you for joining us on today’s call to discuss Moderna, Inc.’s fourth quarter 2025 financial results and business update. You can access the press release issued this morning as well as the slides that we will be reviewing by going to the investors section of our website at investors.modernatx.com. On today’s call are Stéphane Bancel, our Chief Executive Officer; Stephen Hoge, our President; and James Mock, our Chief Financial Officer.

Before we begin, please note that this conference call will include forward-looking statements made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Please see slide two of the accompanying presentation and our SEC filings for important risk factors that could cause our actual performance and results to differ materially from those expressed or implied in these forward-looking statements. With that, I will turn the call over to Stéphane. Thank you, Lavina.

Stéphane Bancel: Good morning or good afternoon, everyone. Thank you for joining us. We will start with a quick review of 2025,

Stéphane Bancel: Jimmy will present our financial results and 2026 outlook. Stephen will review our commercial outlook and clinical programs. And then I will come back and share key value drivers as we look ahead before we take your questions. Let me start with a review of 2025. Revenues were $1,900,000,000, driven by sales of our COVID vaccine Spikevax and MNEXT Spike. We continue to make tremendous progress on cost in 2025. Operating expenses were down $2,200,000,000, or 30% for the year. I would like to thank the entire Moderna, Inc. team for this great accomplishment in 2025. I am very proud of this. Net loss for the year was $2,800,000,000, and we ended the year with $8,100,000,000 in cash and investments. Before I start a review of 2025, I want to express a disappointment with the FDA refusal to file letter on our flu program mRNA-1010. The current uncertainty in the U.S. FDA regulatory environment creates real challenges for businesses, patients, and the broader innovation ecosystem. When expectations and review timelines are unpredictable, companies face greater risk and can hesitate to invest, slowing the development of breakthrough medicines. These delay patient access and increase overall health care costs. Sustained regulatory uncertainty threatens U.S. leadership in innovative medicines. This can also result in transformative medicine developed by U.S. companies becoming available to patients outside the U.S. before reaching American patients. Turning now to the execution on commercial and pipeline. On the commercial side, in 2025, we have three products on the market, Spikevax and MNEXT Spike, and then Emresvia. MNEXT Spike was approved in the U.S. in 2025. It has an excellent launch. It quickly became our leading product in the U.S. In the past two weeks, we announced two commercial agreements. First, an agreement with Recordati for the global commercialization of our propionic acidemia rare disease candidates currently in a pivotal study. Recordati brings deep rare disease commercial expertise and an established global infrastructure with a propionic acidemia community. We also announced earlier this week a five-year strategic agreement with the government of Mexico for respiratory vaccine supply. We currently have two products under regulatory review in multiple countries. Our seasonal flu vaccine is filed and under review in Europe, Canada, and Australia. Our flu plus COVID combination vaccine is filed and under review in Europe and Canada. Additionally, we made strong programs across the pipeline. For INT, our individualized cancer therapy, developed in partnership with Merck, we recently reported positive five-year phase 2 data in adjuvant melanoma, demonstrating the durability of clinical benefit, reinforcing our confidence in the program’s long-term potential. I am very happy to announce that we have completed enrollment in our phase 2 study in muscle invasive bladder cancer. This marks three late-stage studies in three different cancer types that are now fully enrolled: adjuvant melanoma, adjuvant renal cell carcinoma, and now muscle invasive bladder cancer. We look forward to the data readout from these studies. For cancer antigen therapy, mRNA-4259, we announced positive phase 1b data and the program is now in phase 2. Our phase 3 norovirus program is now fully enrolled. We could see phase 3 data in 2026. In our PA program, it is still fully enrolled, a registration study, and we could see data in 2026. I am pleased to welcome to Moderna, Inc., our new Chief Development Officer and Executive Committee member, Dr. David Berman. He has contributed to the development of more than a dozen clinical-stage immunotherapies at BMS and AstraZeneca. His expertise will serve Moderna, Inc. well, as we continue to expand our oncology pipeline. David served most recently as Head of R&D at Immunocore. We very much look forward to David joining Moderna, Inc.’s team on March 2. I would like, of course, to take this opportunity to thank Jackie Miller for her many contributions in the very last five years of the company, especially her tremendous leadership during the pandemic. With this, I would like to turn it over to Jamie. Thanks, Stéphane, and hello, everyone.

Today, I will cover our fourth quarter and full year 2025 results, and then wrap up with our 2026 financial framework. I will begin with our 2025 revenue performance on slide eight. For the fourth quarter, total revenue was $700,000,000, coming in at the higher end of our recent guidance. Our revenue split in the quarter was $300,000,000 in the U.S., and $400,000,000 from international markets.

For the full year, total revenue was $1,900,000,000, with the majority generated from COVID vaccine sales, along with approximately $100,000,000 of other revenue. From a geographic perspective, U.S. revenue totaled $1,200,000,000 while international revenue was $700,000,000. In the U.S., while overall COVID market demand declined year over year, we had strong market share in the retail channel supported by the successful launch of MNEXT Spike. In international markets, we landed at the higher end of our range driven by operational performance and vaccination rates, which were above or in line with our expectations.

Turning to slide nine, I will review our fourth quarter results. As we discussed on the prior slide, revenue was $700,000,000. Compared to the fourth quarter of last year, operating expenses were down 31%, reflecting continued cost discipline and execution across the organization. I will discuss these expense trends from a full year perspective on the next slide. Net loss for the quarter was $800,000,000 compared to a net loss of $1,100,000,000 in 2024. Loss per share was $2.11, compared to a loss per share of $2.91 last year.

Now turning to slide 10, I will walk through our full year 2025 financial results. As I mentioned earlier, total revenue was $1,900,000,000. Cost of sales was $868,000,000, representing a 41% decrease compared to 2024, primarily driven by productivity, lower inventory write-downs, contract manufacturing wind-down costs, and sales volumes. R&D expenses were $3,100,000,000, representing a 31% decrease compared to 2024, driven by continued investment prioritization and efficiency gains in the execution of our clinical trials. These reductions were partially offset by increased investment in our norovirus vaccine and oncology programs.

SG&A expenses were $1,000,000,000, representing a 13% decrease compared to 2024. The decline was driven across all functions and reflects our continued focus on operating efficiently while supporting the business in a disciplined manner. Our income tax provision for 2025 was immaterial. We continue to maintain a global valuation allowance against the majority of our deferred tax assets, which limits our ability to recognize tax benefits from losses. Net loss for the full year was $2,800,000,000 compared to a net loss of $3,600,000,000 in 2024. Loss per share was $7.26 compared to a loss per share of $9.28 last year.

We ended 2025 with cash and investments of $8,100,000,000 compared to $9,500,000,000 at the end of 2024. The year-over-year decrease was primarily driven by operating losses, as we continue to invest in R&D and advance our pipeline.

Stéphane Bancel: Partially offset by the $600,000,000 initial draw

of our $1,500,000,000 credit facility. Excluding the credit facility draw, we would have ended the year with $7,600,000,000 of cash and investments, which was above our 3Q guidance of $6.5 to $7,000,000,000 due to lower operating expenses, lower capital expenditures, and working capital improvements. Now let us turn to our financial framework for 2026. We expect total revenue growth of up to 10% in 2026. This growth is expected to come primarily from international markets. We estimate our geographic mix will be well balanced between the U.S. and markets outside the U.S. in 2026. This is a shift from our 2025 revenue split of approximately 62% U.S. and 38% international.

We will begin selling locally manufactured products in both the U.K. and Australia in 2026, which is the largest driver of our international growth. Our 2026 revenue guidance factors in future potential declines in COVID vaccination rates and also assumes no revenue from our flu vaccine or our flu COVID combination vaccine. Similar to 2025, we expect 2026 revenue to be weighted to the second half of the year with approximately 15% of our revenue in the first half and approximately 85% in the second half. Cost of sales is projected to be approximately $900,000,000. While this is flat year over year in absolute terms, we are expecting gross margin rate improvement from manufacturing efficiency gains and volume leverage.

R&D expenses are anticipated to be approximately $3,000,000,000 as we continue to invest in our late-stage pipeline while maintaining financial discipline. It is a relatively small decline from the $3,100,000,000 we had in 2025 due to the continued execution of our late-stage trials in infectious disease. For modeling purposes, we expect our R&D spend to be relatively balanced in the first half versus the second half of 2026, similar to what we experienced in 2025. SG&A expenses are expected to be $1,000,000,000, flat versus the prior year. We remain focused on driving efficiency and cost savings across the organization, which we will use to fund new commercial investments to support both geographic expansion and future product launches.

Similar to 2025, our commercial spend will be more heavily weighted to the back half of the year, due to the seasonality of our commercial business. In aggregate, we are expecting total GAAP operating expenses of $4,900,000,000 and $4,200,000,000 of cash costs, which excludes stock-based compensation, depreciation, and amortization. We expect taxes to be negligible in 2026. Capital expenditures are projected to be between $200,000,000 and $300,000,000. This guidance includes our previously announced investment in building our own fill-finish capacity in the United States at our existing site in Norwood, Massachusetts.

We expect to end 2026 with $5.5 to $6,000,000,000 of cash and investments. Our cash guidance does not assume any additional drawdown from our credit facility. In summary, 2025 was a key turning point in our financial story. We improved our commercial execution, exceeded our cost reduction plan by over $1,000,000,000 compared to our original 2025 guidance, and ended the year with over $2,000,000,000 more cash, all while still advancing our pipeline.

I want to thank the entire Moderna, Inc. team for their efforts over this past year. We have strong momentum heading into 2026 with multiple levers for revenue growth and a strong commitment to drive additional cost reductions across the company. With that, I will now turn the call over to Stephen. Thank you, Jamie, and good morning or good afternoon, everyone.

Today, I will review our commercial outlook as well as progress across our pipeline. As Jamie mentioned earlier, we expect 2026 to mark a return to revenue growth for Moderna, Inc. This year, we expect growth to be driven primarily by our strategic partnerships and the second year of launch for MNEXT Spike, which I will discuss in more detail in a moment.

But first, looking forward to 2027, we see three additional growth drivers.

We look forward to significant expansion of our addressable market, with the opening of the $1,800,000,000 European respiratory vaccines market,

As a reminder, we have been excluded from this region for several years due to a competitor

pandemic contract, which expires in 2026. We expect to launch MNEXT Spike, our stand-alone flu vaccine mRNA-1010, and our combination flu COVID vaccine in the European region by the 2027 winter season, adding to Emresvia and Spikevax, which are already approved. This broad portfolio represents the opportunity to grow our share in the large European market, which will contribute to meaningful revenue growth from 2027 forward. Second, we expect growth from our new multiyear strategic agreements in Latin America and Asia Pacific. And third, with the acceptance of our flu filings in Europe, Canada, and Australia, we anticipate that our flu vaccine will begin to contribute to revenue internationally.

In 2028, we expect continued new product-driven growth opportunities with both our combination flu COVID and norovirus vaccines potentially being launched across many of our markets. Recent execution supports this growth strategy with approvals for MNEXT Spike in Canada and Australia and the approval of our strain-updated Spikevax COVID vaccine in the U.K. We have already shown strong momentum against the 2027 growth drivers. We announced a multiyear strategic agreement with Mexico earlier this week, and Taiwan last month.

And we continue to make progress under our previously announced strategic agreement in Brazil. Finally, although not a major driver, we also signed a global commercialization collaboration in PA with Recordati, as we prepare that potential launch in 2028.

The U.K. is the

Let us take a closer look at the key contributors to that growth in 2026. Beginning with our strategic partnerships with the U.K., Canada, and Australia. As a reminder, these are long-term agreements under which Moderna, Inc. has built local manufacturing sites and committed to ongoing domestic research and development. These partnerships are core to each country’s national security and public health strategy, strengthening preparedness against current viruses and future pandemic threats. The U.K. is the largest of these markets, and we expect a $200,000,000 U.K.

COVID order to be fulfilled in 2026 for their spring booster campaign. We also expect to supply vaccines for the U.K.’s fall vaccination campaign, initially this year for COVID with the potential to expand to other respiratory vaccines such as flu, RSV, and our combination vaccine in the years ahead. In Canada, we were thrilled to deliver made-in-Canada COVID vaccines in 2025 and expect to see the full annualized impact of the agreement in 2026. And in Australia, we expect to deliver the full annualized benefit of our agreement in 2026 as well. Moving to slide 15, our second major expected growth driver in 2026 is our new COVID vaccine, MNEXT Spike.

MNEXT Spike had a very successful launch in 2025. This is especially notable because MNEXT Spike was approved midyear in 2025 and was only available commercially in the United States. We are extremely pleased with the market share achieved in that first season, with 24% of the total U.S. retail market and 34% of the retail market among adults aged 65 and older. As a reminder, the retail market is the largest customer segment, representing approximately three quarters of the U.S. COVID market, and the majority of that volume is in seniors.

Looking ahead to 2026, we expect to continue to drive the uptake of MNEXT Spike in the United States. And internationally, we look forward to approvals and launches in multiple countries this year and the years to come. Moving to slide 16. This outlines the latest developments in our infectious disease portfolio. Starting with our approved products, the updated formulation of Spikevax is approved in countries around the world.

And importantly, in 2025, we received supplemental BLA approval in the United States for high-risk children as young as six months. As mentioned earlier, MNEXT Spike was approved and launched in the U.S. It was approved in Canada in 2025, and recently approved in Australia as well. We are targeting further approvals of MNEXT Spike in Europe, Japan, and Taiwan this year.

Emresvia, our RSV vaccine, has been approved for adults aged 60 and older in 40 countries, and approved for high-risk adults aged 18 to 59 in 31 of those 40 countries. In addition to those three approved vaccines, we have filed for two additional approvals. mRNA-1010, our flu vaccine, has been accepted for review in Europe, Canada, and Australia, with the first potential approvals coming late in 2026 or early 2027. We were disappointed with the FDA’s refusal to file letter for mRNA-1010 and have requested a Type A meeting to understand the path forward for the program in the United States. mRNA-1083, our flu plus COVID combination vaccine, is under review in Europe and Canada, with first potential approvals in 2026. And finally, our norovirus vaccine is in an ongoing phase 3 trial, which is fully enrolled in its second Northern Hemisphere season and is accruing cases towards its interim analysis.

Now turning to our therapeutics pipeline. INT, our individualized cancer therapy, developed in collaboration with Merck, has a total of eight phase 2 or phase 3 studies ongoing. The most advanced of these are our phase 3 adjuvant melanoma study, as well as our phase 2 randomized adjuvant renal cell carcinoma study, both of which have been previously announced as fully enrolled. As Stéphane mentioned previously, we are very excited to announce that we have now fully enrolled our phase 2 randomized muscle invasive bladder cancer study.

Bladder cancer is the third cancer type now in a fully enrolled late-stage study. In addition to these three trials, we are looking forward to completing enrollment in our ongoing phase 3 studies in adjuvant non-small cell lung cancer. We also look forward to completing enrollment in our ongoing phase 2 trials in non-muscle invasive bladder cancer, first-line metastatic melanoma, and first-line metastatic squamous non-small cell lung cancer. Beyond these phase 2 and phase 3 studies, we are fully enrolled in our phase 1 studies for adjuvant pancreatic cancer and perioperative gastric cancer, and we look forward to data from these studies in the year ahead.

Aside from INT, aside from our collaboration in INT with Merck, we continue to make progress in additional oncology programs. In the phase 2 study of our cancer antigen therapy mRNA-4309, cohorts are enrolling in first-line metastatic melanoma, second-line metastatic melanoma, and first-line metastatic non-small cell lung cancer. In mRNA-2808, our T cell engager in multiple myeloma, we are dosing in our phase 1/2 study. We are also dosing in the phase 1 study of our cancer antigen therapy mRNA-4106. And rounding out our early-stage oncology programs, our phase 1 study is also dosing in our cell therapy enhancing program, mRNA-4203, in collaboration with Immatics.

In rare diseases, our propionic acidemia, or PA, program is fully enrolled in its registrational study, and in methylmalonic acidemia, or MMA, we expect our registrational study to start in 2026. With that, I will hand the call back over to Stéphane. Thank you, Stephen and Jamie.

Stéphane Bancel: Looking ahead, we see multiple commercial, pipeline, and financial value drivers that will move Moderna, Inc. forward in 2026. Commercially, we believe the market share gains from MNEXT Spike continue into 2026 and beyond. We will also benefit from a full-year contribution from our strategic partnerships in the U.K., Canada, and Australia. That will be an important growth driver for Moderna, Inc. in 2026.

And we expect up to 10% revenue growth in 2026.

Stéphane Bancel: From a pipeline standpoint, we look forward to potential regulatory approval of MNEXT Spike in Europe, in Japan, and in Taiwan. We also expect potential approval of our combination flu plus COVID vaccine in Europe and Canada, where regulatory filings are under review. In the U.S., we plan to refile pending further guidance from the FDA. For the seasonal flu vaccine, we look forward to the approval in Canada this year. It is going to be an important year for oncology patients and for Moderna, Inc. We also expect continued clinical momentum from our INT program as Stephen described. Last month, we reported positive five-year phase 2 data in adjuvant melanoma. Potential clinical milestones from the INT program include phase 3 adjuvant melanoma data, phase 2 adjuvant renal cell carcinoma data, and phase 1 data in adjuvant pancreatic and perioperative gastric cancers, all of which have been fully enrolled for quite some time. We also look forward to a phase 2 readout from our cancer antigen therapy mRNA-359, the phase 2 results for norovirus, and the pivotal data readout from our PA program. It will be a busy year. From a financial standpoint, teams across the company continue to make progress on cost discipline, and we expect cash costs to decline to approximately $4,200,000,000 in the year. As part of our cost efficiency program, the adoption of AI tools has touched every part of our business, and we expect further productivity improvement in 2026. Moderna, Inc. has strong momentum as we head into 2026. We are poised to deliver up to 10% revenue growth as we continue to reduce costs. We expect to see approvals of infectious disease vaccines that will expand our commercial portfolio. We foresee multiple potential clinical data catalysts driven by our late-stage oncology programs, in rare disease and infectious disease. In closing, I want to recognize the entire Moderna, Inc. team for their relentless drive. All our progress—clinical, commercial, operational—is dedicated to one mission, delivering the greatest possible impact to people from mRNA medicine. With this, Operator, we will be happy to take questions.

Thank you. Ladies and gentlemen, if you have a question or a comment at this time, please press *11. If your question has been answered and you wish to remove yourself from the queue, please press *11 again. Our first question comes from Terence Flynn with Morgan Stanley. Your line is open.

Hi. Thanks so much for taking the question. I had two-part. I guess the first one is just on the flu RTF, implications for the 2028 cash flow breakeven guidance, and then timing of the Type A meeting, when you might get some visibility on next steps. And then

Stéphane Bancel: INT

program in adjuvant melanoma, I know that is a very important program and catalyst for the company. And so, can you refine at all the timing of that data, whether it is going to be first half or second half? Thank you so much.

Sure. Maybe I will take the questions on regulatory first, and then, Jamie, hand it over to you on any breakeven implications. So, we are actually very pleased that the flu file is under review now in Europe, Canada, and Australia. We will be filing in additional countries this year.

And all of that is with an eye towards having that start contribute, as I said a moment ago, in 2027, to our growth. We also are pleased that the flu COVID combination product remains under review and making progress in Europe for this year. As relates to the U.S. timing, we really need to engage with the FDA in the Type A meeting. That is usually 30 days as a process and understand from them what is going to be required to get that product moving forward in the U.S.

We absolutely feel that American seniors should have access to the same innovations. We do think this year, in particular, where there is a potential for a mismatch in one of the strains, it is particularly important that technologies like Moderna, Inc.’s mRNA platform are used to advance new and potentially improved products. But at this point, until we have that Type A meeting, we will not really know how quickly we can get moving forward with the 1010 file in the U.S. as we have been doing outside the U.S. Jamie?

Yeah. So, Terence, thanks for the question. I appreciate it, and I recognize that it is on investors’ minds. As Stephen just said, though, this is a bit of a fresh and fluid situation.

And without understanding the resolution of what is next for our flu product, it is a little bit difficult to comment at this time. But here is what I would say. If you go back to the growth drivers we laid out at Analyst Day as well as Stephen had in his prepared remarks, we have 10 large shots on goal to increase revenue over the coming years, all with a wide range of potential outcomes. And Stephen mentioned some of the progress.

We announced our long-term partnerships with Mexico and Taiwan. We are excited about, as I said, we are excited to deliver for the U.K. and Australia this year, which will be substantial revenue growth. MNEXT Spike had a great first year. We are excited about the second year, both in the U.S. and outside the United States.

We are looking forward to Europe opening up. So there are really still so many scenarios that could happen here, Terence, that it is a little bit too early to tell. On top of that, we have a ton of momentum on what we are doing from a cost perspective. So we are really excited about our financial profile.

We ended the year with over $8,000,000,000 in cash. We have a ton of momentum from a cost perspective, and we have a lot of opportunities for growth. So at this point, without knowing resolution to what is going to happen on flu, I think it is a little too early to tell.

And on INT, the second question, we do not have obviously more specific guidance than we previously put out there. I had highlighted, I said, a moment ago, that there are five histologies now under the different stages of clinical development. So INT for melanoma, the adjuvant melanoma study, is one that we are confident will read out this year. It is an event-driven trial, and so it depends upon the accrual of those events.

We have RCC, so renal cell, and bladder now fully enrolled. And so, again, those are going to be event-driven and milestone-driven. It is possible. And then the phase 1 data that we referenced before for our peri-adjuvant gastric and adjuvant pancreatic monotherapy cohort.

And so it is going to be a busy year for us over the next number of months. But we do not have more specific guidance because some of the most important readouts are ultimately event-driven.

Thank you. One moment for our next question.

Our next

question comes from Salveen Richter with Goldman Sachs. Your line is open.

Good morning. Thank you for taking our question. This is Elizabeth on

for Salveen. We wanted to ask about the flu and COVID combination vaccine and, just given the RTF for 1010, how should we think about this refiling, and is there any read-through from a regulatory in the U.S.? And then maybe just remind us of the study data that went into the submission initially, and what the latest thinking is on what might need to be added for refiling. And then a second question on INT.

We wanted your thoughts on which of those five histologies you just mentioned have the highest probability of success, kind of based on the read-through from data generated to date? Thank you so much.

Thanks for both questions. You know, so first, on the 1083 file, again, I will underscore that we are hoping for approval of the flu COVID combination product in Europe first, this year. And so we will move forward there. As it relates to the U.S., we were holding back on refiling the combo vaccine until we had completed some portion of the review of the flu vaccine.

With the refusal to start the review of the flu vaccine, I think that is now gated on, again, the feedback from the Type A meeting, which we have not had, about what more would be necessary for us to refile for the mRNA-1010 program. And then we would be able to provide more clarity on the flu COVID program and refiling there, again, all of this in the U.S. because all those files are moving forward internationally. You asked about the data that was in the file. We had a phase 3 study for the mRNA-1010 file, which we have previously presented the results on.

And actually, it is out for a peer-review publication right now. We are really excited by that phase 3 study, which is a randomized 41,000-person study that we had agreed with the FDA and agencies around the world prior to initiation. In that study, as a reminder, we saw 27% superior relative vaccine efficacy compared to the standard dose control. And just to give you a sense of where that stands relative to comparators, you know, two of the 65+ vaccines had run essentially the same study design, one of them even with exactly the same comparator.

And those, if you look at the USPI for Fluzone, they had seen 24% relative vaccine efficacy; for Flublok, if you look in their USPI, you see 30% relative vaccine efficacy. So at 27%, we felt very good that we were in line, in demonstrating superiority in exactly the same way that those standard of cares have, in the same population, those over the age of 65. We also ran a phase 3 study, an immunogenicity and safety study, comparing our vaccine candidate for flu against Fluzone High-Dose, and in that case, we showed statistical superiority to Fluzone High-Dose on immunogenicity. That study has been published in the journal Vaccine and is available, I think, on our website, for those who are interested.

So that package was in the initial file. We think it is a very comprehensive dataset. We do think if we can get the review initiated, it will support the use of the product. But we do need to understand first from FDA in that Type A meeting what they would need to initiate the review of the file that they previously had agreed to review.

Moving to INT, I think it is obvious that you asked where we see the highest probability of success. It is hard to argue with the phase 2b results that we have for adjuvant melanoma. As we announced last month, the five-year survival data continues to look really strong, approximately 50% reduction in the rates of relapse or death from melanoma. Real stability in those curves through now five years.

And if you ask me where do I think the read-through of that is, I think it is clearly, we hope, into the phase 3 adjuvant melanoma study that is testing in largely the same population, exactly the same standard of care. You know, I think if it works, we see that there. One of the reasons we and our partner Merck went in with renal cell and bladder, muscle invasive urothelial cell carcinoma, is we thought those would be places where we might also see relatively quick read-through. And so I hope that those also have positive readouts, but I think you are asking where we think the probability of success is highest.

It is clearly in the phase 3 adjuvant melanoma.

Thank you. One moment for our next question. Our next question comes from Eliana Merle with Barclays. Your line is open.

Just can you elaborate a little bit on how you are thinking about the European COVID vaccination market and how you see the vaccination rate and pricing evolving there? And also how, outside of the U.S., you are thinking about the pathway for a potential flu COVID combination vaccine approval? And then also on that topic around flu, just in your filings for flu in Europe and Canada, has there been any discussion around potential strain selection in the future and potentially selecting the strains closer to the season? Thanks.

Yeah. Thank you for all three. So, first, I will take the COVID question. MNEXT Spike is moving forward with approvals internationally, and we are really pleased with the profile of that product.

As I will remind you, we had demonstrated, in that phase 3 study, higher relative vaccine efficacy. In fact, in a post hoc analysis, very high, approximately 25% higher relative vaccine efficacy compared to Spikevax in older adults with comorbidities. And so we really do think it has got a strong profile as the European COVID market reopens. Now as to pricing, you know, we have not issued that yet, but we do believe that the current market is, as we have shared, approximately 700,000,000 shots today, and that does not account for waste that exists in the market.

There are many doses that are being purchased under pandemic contracts that are not getting used. That estimate of approximately 700,000,000 is just what we see as shots in arms. So we do believe that market will be larger than that, larger than even if we see nothing more than the approximately 20,000,000 shots in arms that currently are happening. And we do hope to get a sizable share.

We think MNEXT Spike will be a very competitive product profile in that market. And we are scaling up for that launch. As you know, Europe is not one market. It is a series of different markets, and some places we will compete traditionally with sales and marketing activities.

Other markets are more tender-driven, and we are preparing for all of those activities, really starting this year, but as we said, as a meaningful driver of growth in 2027 and beyond. On the combination product, we actually think that is the next step in that strategy. We are very pleased by the combo product’s progress in its international reviews. As we have said, based on timing, we do expect a European review to move forward, and we are hoping for approval this year, which gives us a chance to launch as early as this year, more likely in 2027. Again, it just depends on timing of these events because proximity to the season will make a launch very difficult.

But it is clearly a great opportunity for us to move beyond just COVID in a combination product and an opportunity to both expand our share in the COVID space but also grab share in the flu space. And we are proceeding with the filings elsewhere. I think we referenced in the press release Canada for that combination product as well, and hope to similarly bring forward that innovation because we believe there is strong demand from health systems as well as patients for one shot, or one vaccine, that does multiple things. Now as it relates to the flu, we have been having those conversations.

So mRNA-1010, as we have proceeded outside of the U.S., there has been strong appetite for the question of better strain matching. And in fact, in some public comments, you have seen some European regulators, but also some from other markets, locally advocate for later strain selection and more diverse strain selections happening in flu vaccines because of the precedent we have shown with COVID vaccines. I will remind you that we sometimes forget in the U.S., but in this country, the FDA has chosen different strains of COVID vaccine than the rest of the world in two out of the four past seasons.

And the data has shown that that better matching for the market has led to slightly better efficacy. In fact, we ran a clinical trial once head-to-head back in the bivalent days and showed higher point estimates for efficacy, which makes sense. A better matched vaccine, you would expect to be better at protecting people. And what we are hearing from the international flu community, including, as I said, in Europe, is quite strong support for that.

It is a real question today. I mean, just to make the point, there are a couple of different strains of influenza B circulating around the world right now. In the United States, it is a different strain than is circulating in the rest of the Northern Hemisphere, and there does not look like there would be great cross-protection. And so it just highlights that the right answer for this fall could be very different from a composition perspective for Europe, or North America, or other regions.

And that is where the technology that we have that has allowed us to tailor and meet regional needs with COVID, we think, can have an impact. There are many other things we need to do to improve flu vaccines. This is one we know we can do right now.

Thank you. One moment for our next question. Our next question comes from Tyler Van Buren with TD Cowen. Your line is open.

This is Greg on for Tyler from TD Cowen. Some investors have been surprised by the higher-than-expected cash balance at year-end. So can you explain why that occurred and what the additional levers to lower cash costs are moving forward? Thanks.

Yeah. Sure, Greg. So maybe I will just go back to our original guidance. When we laid out our original guidance, we said $1.5 to $2.5 billion of revenue, so $2,000,000,000 at the midpoint.

And we said $5.5 billion of cash costs. So if you take those two together, it is a $3.5 billion usage, from a starting point of $9.5 billion, which is why we guided to $6,000,000,000. Since then, revenue essentially came in online. We have $1.44. Let us call that pretty close. And cash costs came in at $4.3. So we beat by $1,200,000,000. On top of that, we took $600,000,000 of the initial draw from the loan.

So that is now $1,800,000,000 better. Our capital expenditures were $100,000,000 less than we forecast at the outset of the year, so that is $1,900,000,000 better. Then if you look at the working capital, I am really pleased. It does not get a lot of attention, with how the team has performed.

Our receivables are at $180,000,000. Inventory was flat year over year at $270,000,000. Payables at $300,000,000. We have a net working capital balance of $150,000,000 to which we run this company, and that is really incredible performance from the team, and that drove the last $200,000,000. So I do not think it should be too much of a surprise that it is mostly cash costs, $1,200,000,000 above our original guidance, the loan, a little bit less capital expenditures, and then terrific performance on working capital from the team.

Thank you. One moment for our next question.

Our next question comes

from Michael Yee with UBS. Your line is open.

Great. Thanks. We had two questions as well.

First, on the adjuvant phase 3 melanoma study, can you remind us

that that study has interims built in and then, of course, a final? And so, like other design studies you have done, there is a certain number of cases accrue, you take a look at it, then if it does not stop, you move to the next case, next interim. Can you just describe a little bit how that works and remind us the phase 2, I think, did stop at an interim, if I was correct there? And then on norovirus, I do not think anyone has asked on that, but can you just remind us there you are enrolling or expect to complete enrollment, and then there is actually a readout, I think, planned this year.

What is your confidence level there? I know there have been a lot of disappointments previously, but I think you are targeting a different approach and using three different strains, which I think I assume you believe will capture the majority of coverage. Can you just remind us there how you think about that result? Thank you.

Yes. Thanks, Mike, for both questions. So first on the INT phase 3 for adjuvant melanoma. You are correct, the first analysis that we will see this year will be an interim analysis, looking at our primary endpoints of relapse-free survival.

We have a number of additional analyses. If you get there and we do not have the power to declare early success, then we would move forward to subsequent analyses, and ultimately additional endpoints, including things like distant metastasis-free survival. What I would remind you is the phase 2 hit essentially its statistical hypothesis at the interim. Then what we have been following since are the others.

And we believe we have conservatively designed this study so that if those results are repeated, we would be well powered to see that in this first interim. But if, for whatever reason, we are told to continue forward, there would be a subsequent analysis. And that, again, would be event-driven but presumably would come, you know, the year after. As to the norovirus study, we are very excited to see those results potentially this year.

Again, a case-driven trial. As you highlighted, there have been some previous efforts in norovirus. Ours are quite different. So first, the composition of our vaccine, as you highlighted, is a trivalent here, and we are looking at strain-matched efficacy, which is important because it does allow us to make sure that we are looking at the performance of the vaccine, which is matched at strains that are in, you know, approximately, in most years, two-thirds to 70% of the circulating norovirus disease.

And so that trivalent composition and the VLP that our technology makes, we think, is a differentiator. But perhaps the more important one relative to the trial I think you were referencing is we are looking in seropositive populations, not children. And so earlier studies that have struggled in norovirus have looked in children in primary vaccination, you know, often a couple of doses, as opposed to really where the burden of disease is as you become an adult, which is in older adults, those particularly over the age of 65, where, you know, the threat of really profound dehydration can lead to hospitalization and complications of a whole number of medical comorbidities.

And so there is actually an even bigger need in that population. And in that case, it is more of a booster trial. It is much more like, you know, it is a bit like primary vaccination for RSV or flu or COVID being very, very different than boosting seropositive people so that they can protect, which is a lot more like what you see with our senior flu, COVID, and RSV vaccines, which have obviously been successful. Norovirus is a different one, but we do believe that that difference in population will make a difference in terms of the ability of a vaccine to help protect them against this disease.

Thank you. And as a follow-up, do you think that the guidance with FDA or the discussion or regulatory path for this would be very different or, put another way, much more obvious than perhaps what is going on with flu?

So, look, Michael, I

I would remind that we have got three products approved last year in the U.S., you know, some label expansions, RSV, a new COVID product, and a pediatric COVID. And, you know, in those cases, you know, the guidance was different. What we are experiencing with flu is, I think, we hope, flu-specific. Our norovirus study, to your point, is a very large, placebo-controlled study.

And so the refusal to file letter that we have received from the FDA on flu really speaks to a change in their perspective on the comparator used. But in the case of norovirus, there is no comparator to use. And so the comparator in that clinical trial is placebo. If we are able to demonstrate efficacy over placebo, it is hard to argue that there is a problem with the comparator.

Perfect. Thank you.

One moment for our next question. Our next question comes from Luca Issi with RBC Capital Markets. Your line is open.

Oh, great. Hi, team. This is Shelby on for Luca, and thanks

for taking the question. Maybe on INT, congrats on the recent five-year data for melanoma. And it is great to see the hazard ratio for RFS remaining consistent with prior cuts. However, what about OS?

I remember at ASCO in 2024, you showed some pretty compelling data with the initial separation of the curve. But the press release this time was silent on OS. How should we read that? Does that mean the OS curves are no longer separated, or are you just keeping the details for maybe an upcoming medical meeting?

Any color there much appreciated.

Thanks.

Yeah. Let me say it this way.

We look forward to sharing the OS curves at an upcoming medical meeting. We, you know, where you see relapse-free survival holding, obviously included in relapse-free survival is survival. And so we obviously did not put that out because we want to make sure that we are able to bring that forward to the community in a place where they can see all of that data. But all data from this five-year interim analysis will be presented at an upcoming medical meeting.

Until then, I really should not say more.

Thank you. One moment for our next question. Our next question comes from Courtney Breen with Bernstein. Your line is open.

Hi. Thanks so much for taking our question today.

Just a couple and building off the conversation around the RTF that you got for the flu 1010. We had defined kind of as an immunogenicity sub-study, I think, of that phase 3 efficacy study, which suggested, and it was a very small population of that study, suggested there was a 50/50 ratio between those under and over 65. Can you just remind us or share with us what percentage of patients

in that efficacy study were 65 or older?

And then, additionally, as we think about kind of

INT and the path to approval and kind of

have you had any feedback in the design of that clinical trial that perhaps provided some recommendations that were not followed? Additionally,

kind of will it be you or Merck taking that file forward and can we assume that CBER will be the FDA group that will

assess that particular file? Thank you so much.

Yeah. Thank you for the questions. So first on the phase 3 trial design for our flu vaccine, you are correct and your memory is right. More than 50% of the population of the study was stratified that at least 50% would be 65+.

We also had a very large population of, you know, north of 10% that was above the age of 75. And as we have presented at medical meetings, and will be available in the upcoming publication, we have seen really strong superior efficacy across all of those populations. In fact, it is remarkably consistent, and as you add frailty or other risk factors to age, or as you look to severe outcomes such as hospitalization, you will see those point estimates for superiority go even higher, and in many cases become even more statistically significant. So we feel very good about that 41,000-person study, which, as you just described or as I just said, has more than 20,000 people over the age of 65 in it.

I did describe a separate phase 3 study just to avoid confusion, the P303 study Part C. That has 3,000 people in it, and that was the study that was head-to-head against Fluzone High-Dose. That showed superior immunogenicity. But the efficacy study, I think, was the one that you were asking about.

Now as it relates to INT, INT is—we are moving forward in a very novel field. And so we have had robust and, I would say, highly productive engagement with the FDA and truly global regulators around what will be a first-of-its-kind individualized neoantigen treatment. Those dialogues are detailed and, you know, I think, you know, broadly, we are very aligned, both ourselves and Merck, with those regulators. It is with CBER at FDA.

Obviously, other offices are involved because it is, as an oncology therapy of high import, it gets a lot of attention. And I would just say, generally, we are working closely with regulators to make sure that we are doing everything they want so that they can conduct rapid reviews of the file. Merck is our partner in this. Merck is the sponsor for the phase 3 study.

So we and they participate in those discussions and back and forth, and we each have different responsibilities in our 50/50 joint venture partnership. But the BLA submission, if it goes forward, will be from Merck.

Thank you. One moment for our next question. Our next question comes from Alex Rinnehan with Bank of America. Your line is open. Open. Hey, guys. This is Matthew on for Alex.

Appreciate you taking our questions. Maybe for RCC, can you walk us through what makes you confident that phase 2 could be registrational and what hazard ratio or benefit you think would be compelling? And then if you do need to run a phase 3, curious whether you think Keytruda would be the appropriate comparator arm or whether Keytruda + belzutifan combo would be preferred, pending the LITESPARK-022 data. Thanks.

Yeah. That is a great question. You know, one of the

exciting things in oncology is it is a fast-moving space. And in individual histologies, sometimes the standard of care will evolve, and you are highlighting belzutifan for RCC. Look, first, I would say the phase 2 study is blinded, it is powered, and if we see a really profound benefit—we have not guided on what that hazard ratio would be—but let us assume it is something that would look really dramatic and highly statistically significant, then it is structured so that it could be a registrational study. But, you know, it was not initially intended and powered as that.

It is not a phase 3 study because our primary goal here was we wanted to confirm the hypothesis that INT works well across a range of tumors, and in particular places that we thought there was an opportunity to improve upon pembro as a standard of care. And since we started and enrolled that study, there has obviously been the good news of the belzutifan results. Again, that is with our partner Merck. And so, if we see equally great response here for INT, we will have a conversation with Merck about what we do with INT.

It may mean going forward. It may mean adding it to those, because there is always a desire to improve outcomes in cancer. It will entirely depend upon what the data actually says. And so at this point, we are just excited to look forward to it.

But once we have it, the thing that, you know, I think we will be most focused on is does this confirm the opportunity for INT to work across a range of different cancers, other histologies.

Thank you. One moment for our next question. Our next question comes from Cory Kasimov with Evercore. Your line is open.

Hi. This is Adi on for Corey.

We had a question on the adjuvant melanoma

as well. Could you share how do you anticipate use

Stéphane Bancel: across the broader PD-1, PD-L1 class

or primarily only with pembrolizumab? Separately, as pembro and other options become more prevalent, do you see any impact on regimen selection, logistics, or ultimately uptake for INT?

Thank you for both questions. So first, I think we will be pursuing a label—obviously, it is on top of a standard of care in the trial, which is pembro. But we believe that that label could broadly apply to other PD-1, PD-L1s that are approved in the same indication for adjuvant melanoma. Obviously, that will depend upon discussions with regulators, but I think that would follow the precedent of other approaches.

And it is in our mutual interest with Merck. We want to see INT be used for as many patients as possible regardless of the choice of the PD-1 or PD-L1 backbone. As relates to subcutaneous, you know, I think that is really within the PD-1 class question. And so how do those antibodies, you know, get subbed out for each other going forward?

It really would not relate, in our mind, to INT, which would be a category of one, and the benefit that INT provides, we believe, would apply equally well—although we will have to see what regulators want to see—but we think the community would agree that it would likely apply equally well whether you are doing a subcutaneous or IV use of a PD-1 antibody. That is really a question about what they are doing in terms of class share there, because INT will be in a category unto itself.

Thank you.

Ladies and gentlemen, this does conclude the Q&A portion of today’s presentation. I would like to turn the call back to Stéphane for any further remarks.

Stéphane Bancel: Well, thank you very much, everybody, for joining. We look forward to speaking to many of you in the coming hours, days, weeks. Have a great day. Thank you.

Ladies and gentlemen, this does conclude today’s presentation. You may now disconnect, and have a wonderful day.
