A Letter from 
Our CEO
January 6, 2025
Dear fellow shareholders,
As we reflect on 2024, it is clear that the past year brought 
formidable challenges for Moderna along with significant advances, 
particularly for our development pipeline. It was a year of navigating 
a dynamic global landscape and evolving commercial realities, 
demanding resilience, innovation and adaptability.
The shifting dynamics of the COVID and RSV vaccine markets tested 
our commercial strategies and required us to reassess our financial 
framework. These challenges underscored the complexities of 
operating in a post-pandemic world and highlighted the need to 
remain agile within a rapidly evolving healthcare ecosystem.
Additionally, the impending transition within the U.S. government has 
introduced uncertainty regarding policies and priorities shaping our 
industry. Yet, amidst these challenges, our unwavering commitment 
to our Mission to deliver the greatest possible impact to people 
through mRNA medicines has served as our guiding force.
As you know, Moderna was established with the goal of using 
mRNA, an information molecule, to treat and prevent disease 
for people around the world. In a relatively short time, we have 
developed a large number of innovative medicines, advancing 
our Mission and growing our portfolio to two approved medicines, 
seven candidates in Phase 3 trials and a total of 45 programs in our 
development pipeline.
Our unwavering commitment to our Mission 
to deliver the greatest possible impact to 
people through mRNA medicines has served 
as our guiding force.”

Beyond our respiratory portfolio, we prioritized the advancement of five 
non-respiratory programs, with milestones including the initiation of a 
Phase 3 study of our norovirus vaccine, a positive readout of three-year 
data from the Phase 2b trial of our individualized neoantigen therapy (INT), 
as well as the start of our third Phase 3 trial for INT in partnership with 
Merck. We also took steps to move two of our rare disease therapeutic 
programs toward registrational trials.
While we are encouraged by this progress, we recognize opportunities 
for improvement. With a continuous learning mindset, we analyzed these 
outcomes and adapted our business strategy based on our successes and 
challenges. We are confident that with our industry-leading mRNA platform, 
technology, resources and team, we are well-positioned to execute this 
strategy and continue building a future where Moderna leads in healthcare 
innovation, delivering on our Mission for patients in 2025 and beyond.
Our success in research and development is a testament to our platform. 
With a demonstrated probability of success for our mid- and late-stage 
pipeline standing at approximately 69 percent compared to the historical 
industry average of approximately 19 percent, we are redefining what is 
possible in biopharmaceutical innovation. As we demonstrate the higher 
success rates of our development candidates, we believe the value 
ascribed to our broader pipeline based on higher expected probabilities of 
success may increase correspondingly.
Despite the challenges in 2024, we became a multi-product company 
with the approval of mRESVIA®, our RSV vaccine for older adults. With 
the launch of our updated COVID-19 and RSV vaccines, Moderna is now 
the only company with more than one approved mRNA product. We also 
achieved four positive Phase 3 data readouts across our respiratory 
portfolio, further demonstrating our platform’s potential to address 
significant unmet medical needs and advance public health.
Statistics for Moderna based upon internal data and are based 
upon: 26 Phase 1 trials, 12 Phase 2 trials, and 6 Phase 3 trials. Only 
concluded trials for unique molecular entities are included in data; 
strain updates for a program are not counted separately. Early trials 
establishing platfom technology not intended for commercialization 
are excluded from Phase 1 trial counts. Data reported as of 
December 31, 2024. Industry statistics derived from Wong et al., 
Biostatistics (2019) 20, 2, pp 273-286.

A Year of Discipline and Focus
In 2024, we set out with a focus on commercial execution, disciplined 
investment and the advancement of our late-stage pipeline to drive 
organic sales growth. Throughout the year, we exercised financial 
discipline and intensified our focus on building and rebuilding efficiently 
and utilizing technology to further streamline operations to enhance 
productivity across our business after having built so rapidly during the 
pandemic.
In our second full year of commercialization, our share of the COVID 
vaccine market declined due to increased commercial competition. 
Despite all our efforts, the U.S. market volume did not grow. Both were 
disappointing outcomes, and we are adapting our strategy for 2025.
Outside the U.S., our results were mixed, with stronger performance in 
some markets, offset by weaker performance in others. We also faced 
continued exclusion from many European markets by a pandemic-era 
competitor contract with the European Commission.
There are positive signs going into 2025. The market volume for COVID 
vaccines has been relatively stable for two years, and public health 
recommendations for vaccinations are normalizing. We are encouraged 
to see the emergence of a sizable and durable long-term COVID 
vaccine market.
At the same time, we recognize there is more work to do given the 
significant health risks posed by COVID. Vaccination remains critical in 
preventing severe outcomes, mitigating Long COVID and protecting 
communities, especially as U.S. Centers for Disease Control and 
Prevention (CDC) data highlight that adults over 65 are at least three times 
more likely to be hospitalized due to COVID than the flu.¹ Notably, more 
than 95 percent of adults hospitalized in 2023-2024 for COVID had not 
received the latest vaccine.²
This past respiratory season, we also launched mRESVIA, which marked 
our second approved product in the market, building on the strength 
and versatility of our mRNA platform. We and others did not anticipate 
the updated CDC Advisory Committee on Immunization Practices (ACIP) 
guidance, and the resulting contraction in the U.S. market. We were 
also too optimistic about our ability to break into the market given the 
headwinds from a midyear approval and launch. We are taking those 
learnings to heart and going forward, we will not include revenue from 
products in their launch year in our financial framework.
With regard to disciplined investment, we built upon the rightsizing 
of our manufacturing infrastructure in 2023—in line with the resizing of 
the COVID-19 vaccine market due to the shift from a pandemic to an 
endemic market—by driving internal cost control and productivity starting 
in early 2024. By the end of 2024, we reduced our cash operating cost 
by nearly 25 percent compared to the prior year. We also announced our 
expectation to continuously reduce annual research and development 
costs, through portfolio prioritization and cost efficiencies, such that 
by 2027 we will plan to spend approximately $1.1 billion less per year 
compared to 2024.
In 2024, strategic investments in people, processes and technologies 
further enhanced our capabilities. We welcomed to our Board of Directors 
David Rubenstein and Abbas Hussain, who bring tremendous international 
policy experience and global commercial operational expertise.
Expanding our Executive Committee, we promoted Dr. Jacqueline Miller to 
Chief Medical Officer and Dr. Rose Loughlin to Executive Vice President of 
Research. We expanded the responsibilities of two current members with 
Dr. Stephen Hoge, President of Moderna, overseeing strategy for the full 
product lifecycle from Research and Development through Medical Affairs 
and Commercial and Tracey Franklin, Chief Human Resources Officer, 
becoming our Chief People and Digital Technology Officer, emphasizing 
the profound ways in which AI and digital platforms will reshape our ways 
of working and deliver on our Mission.

To create efficiency in how we work, we entered into a collaboration with 
OpenAI. Both of our companies are research-driven organizations pushing 
the boundaries of technology to drive transformation, and collaborations 
with companies like OpenAI are critical to our ability to scale effectively 
and maximize our impact on patients.
Importantly, we invested in the learning and development of our team, 
the engine that drives our science and our culture. As a positive reflection 
on our people and culture, Moderna was recognized for the tenth 
consecutive year by Science Careers as a Top Employer. Additionally, 
Moderna joined the ranks of Fortune’s World’s Most Admired Companies 
for the first time, reflecting our transformative platform and commitment 
to advancing mRNA medicines while fostering an environment where 
people can do their best work.
The Moderna team has made great strides to advance our late-stage 
pipeline. Over the past three years, our robust pipeline has achieved 
milestones across multiple late-stage clinical trials, and our early-stage 
portfolio has produced proof-of-concept data with multiple candidates 
ready for pivotal studies.
In 2024, we understood that our broad clinical success and recent 
commercial challenges necessitated a more selective and paced 
approach to our research and development investment. Indeed, our 
research and development investments through 2027 will potentially 
yield up to 10 product approvals over the next three years, expanding our 
commercial portfolio into oncology, rare diseases and first-in-class non-
respiratory vaccines. We are prepared to make these investments in our 
pipeline without needing additional capital infusion.
We recognize our platform’s productivity needs to be turned into greater 
commercial success. Understanding the hard work that lies ahead, we 
are pacing ourselves. In addition to focusing on these 10 approvals, we 
are going to ensure we do not advance further latent vaccines or rare 
programs into pivotal development until we have shown we are better 
prepared to effectively launch these products into global markets either 
directly or through strategic partners. That is how we will best deliver on 
our commitment to patients.

Advancing mRNA Medicines
At our annual R&D Day in September, we announced our focus on delivering 10 new product approvals over the next three years. The following highlights 
a few notable 2024 milestones from across this prioritized research and development portfolio. 
Respiratory Franchise
In 2024, we announced four positive Phase 3 data readouts across our 
respiratory disease programs, including our next-generation COVID, RSV 
for high-risk adults aged 18 to 59, combination flu/COVID, and seasonal flu 
vaccine candidates. Using a priority review voucher, we proceeded to file 
for approval of our investigational next-generation COVID vaccine, mRNA-
1283, and received a PDUFA date of May 31, 2025, from the U.S. FDA. In 
addition, we initiated a Phase 3 efficacy study, funded by Blackstone Life 
Sciences, for our seasonal flu vaccine candidate, which has demonstrated 
consistently acceptable safety and tolerability across three previous 
Phase 3 trials.
Latent & Other Franchise
We prioritized the development of vaccines against two latent and other 
viruses with unmet or underserved needs: cytomegalovirus (CMV) and 
norovirus. The pivotal Phase 3 study of our CMV vaccine candidate for the 
prevention of primary infection in women of childbearing age is ongoing. 
We will share an update when we receive the efficacy data from the 
independent Data Safety Monitoring Board.
Our trivalent vaccine candidate for the prevention of norovirus advanced 
into a pivotal Phase 3 clinical trial evaluating its efficacy, safety and 
immunogenicity. Norovirus is a significant public health concern that affects 
millions of people worldwide each year, leading to severe symptoms and, 
in some cases, hospitalization. By advancing our investigational norovirus 
vaccine into a Phase 3 study, we are one step closer to potentially providing 
a new tool to prevent infection from this highly contagious enteric virus, 
which places a significant burden on health systems globally.

Oncology Franchise
In 2024, we announced three-year data from the Phase 2b trial evaluating 
INT in combination with Merck’s KEYTRUDA® in patients with resected 
high-risk melanoma. The therapy continued to show a sustained benefit 
in recurrence-free survival and reduced the risk of recurrence or death 
by 49 percent and the risk of distant metastasis or death by 62 percent 
compared to KEYTRUDA alone. These data reinforced our commitment 
to advancing this innovative treatment in collaboration with Merck and to 
transforming cancer therapy for patients.
We were excited to see the continued and durable clinical benefit with our 
mRNA therapy, and to launch a new Phase 3 study with Merck evaluating 
adjuvant INT in combination with KEYTRUDA after neoadjuvant KEYTRUDA 
and chemotherapy in patients with certain types of resected non-small cell 
lung cancer. This is the third Phase 3 trial for the investigational INT focused 
on earlier stages of cancer. To support this continued progress, we have 
advanced the build out of our factory in Marlborough, Massachusetts, which 
will enable the commercial launch for INT.
Rare Disease Franchise
Our rare disease portfolio continued to show promising advancements 
this year as well. In an ongoing Phase 1/2 study designed to evaluate safety 
and pharmacology in trial participants with propionic acidemia (PA), our 
investigational therapeutic was generally well-tolerated to date with no 
events meeting protocol-defined dose-limiting toxicity criteria. Early results 
suggest potential decreases in annualized metabolic decompensation event 
frequency compared to pre-treatment, and the majority of PA patients have 
elected to continue on the open label extension study. The study began 
generating data supportive of registration activities in 2024.
Additionally, our investigational therapeutic for methylmalonic acidemia was 
selected by the U.S. FDA for the Support for Clinical Trials Advancing Rare 
Disease Therapeutics (START) pilot program in 2024. The FDA and Moderna 
have agreed on the pivotal study design, and we expect to start the study in 
the first half of 2025.
We have the largest 
late-stage pipeline  
mRNA medicines in the 
world, and we will 
continue to focus 
on positively impacting 
human health.”

Acting Responsibly
As we continue to make progress in our platform and increase our 
potential to profoundly impact human health, we recognize that building 
the most impactful version of Moderna requires maintaining trust with 
stakeholders, protecting the health of the planet and caring deeply for our 
employees and communities. By meeting at the intersection of science 
and responsibility, I know that we can meaningfully improve the lives of 
patients.
In June, we published our third annual ESG Report, a milestone that 
underscores our commitment to transparency, stakeholder engagement 
and integrating ESG priorities into the heart of our operations. The report 
highlights significant milestones, including the positive impact on more 
than 100 million lives through mRNA medicines and our partnership with 
the Coalition for Epidemic Preparedness Innovations (CEPI) to enhance 
pandemic preparedness. Our mRNA Access program now includes 18 
institutions, and we have achieved 38 percent Global Ethnic Majority 
enrollment in U.S. infectious disease trials. Looking ahead, we are 
committed to net-zero carbon emissions (Scopes 1 & 2 by 2030, Scope 
3 by 2045), fostering inclusion and diversity, sustainable site designs, and 
deepening community engagement to address inequality.
Looking Ahead
In 2025, we are focusing on three priorities. Priority one is to drive sales 
of our Spikevax® and mRESVIA vaccines, which are the foundation of our 
respiratory portfolio. We will continue to work with all market channels 
to maximize the availability of Spikevax. Internationally, we plan to bring 
manufacturing plants online in the U.K., Canada and Australia in 2025. 
Additionally, with a full season of RSV contracting in 2025, we expect to 
increase mRESVIA’s market share in the U.S. and market access globally.
Priority two is to focus on delivering up to 10 product approvals over the 
next three years to drive sales growth and fund the next wave of research 
and development investment. For eight of these programs, we have 
near-term milestones, including the potential approval of our RSV vaccine 
candidate for high-risk adults aged 18 to 49.
Priority three is to continue improving efficiency by keeping our R&D and 
SG&A expenses flat to down in 2025. By 2027, we expect to decrease 
annual R&D expense by $1.1 billion compared to 2024. On the cost 
of sales, we will continue to drive efficiency through manufacturing 
productivity improvements to achieve operating leverage.
In closing, we have the largest late-stage pipeline of mRNA medicines in 
the world, and we will continue to focus on positively impacting human 
health. While there is work to be done to meet our execution targets 
and build our commercial capabilities, I am confident that our team will 
continue to work relentlessly to achieve our goals.
I am deeply thankful for everything the Moderna team does to advance 
our Mission. We will remain focused on creating an environment where 
our employees can have meaningful careers, and where purpose and 
innovation fuel our work.
Thank you to all our shareholders for your continued trust and support 
in our development and delivery of medicines of the highest quality. I 
continue to be excited about the potential we have to deliver for patients.
The actions we are taking will help us fully realize our vision. Our bright 
future is in mRNA medicines.
Warmest regards,
Stéphane Bancel 
Chief Executive Officer

Respiratory syncytial virus
On May 31, 2024, the U.S. Food and Drug Administration (FDA) approved 
mRESVIA®, an mRNA respiratory syncytial virus (RSV) vaccine to protect 
adults aged 60 years and older from lower respiratory tract disease 
caused by RSV infection. The approval was granted under a breakthrough 
therapy designation and marks the second approved mRNA product 
from Moderna. The U.S. FDA’s approval of mRESVIA is based on positive 
data from the Phase 3 clinical trial ConquerRSV, a global study conducted 
in approximately 37,000 adults aged 60 years and older in 22 countries. 
mRESVIA is the only RSV vaccine available in a pre-filled syringe. This 
format offers a convenient, ready-to-use formulation that simplifies the 
process of administering the vaccine, saving healthcare professionals 
time and reducing the risk of administrative errors. 
RSV is highly contagious and affects approximately 64 million people 
around the world each year, with older adults more likely to develop 
severe complications that could require hospitalization. Further, it is 
estimated that 470,000 adults aged 60 or older are hospitalized, and 
33,000 die from RSV infections in high-income countries annually.1
With the approval of mRESVIA in the United States, European Union, Canada, 
Norway, Liechtenstein, Iceland and Qatar, Moderna is the first company in the 
world with two approved mRNA vaccine products.

COVID-19
In August 2024, the U.S. FDA approved Moderna’s updated COVID-19 
vaccine, Spikevax®, for individuals 12 years of age and older. The updated 
vaccine composition targets the KP.2 variant, based on guidance from the 
U.S. FDA. Emergency Use Authorization (EUA) for our COVID-19 Vaccine 
(2024-2025 formula) was also granted for individuals 6 months through 
11 years of age. COVID-19 remains a significant health risk and is a leading 
cause of respiratory illness-related hospitalization, regardless of age or 
health condition. Despite all we have learned about COVID-19, much 
remains unknown about its long-term symptoms, a syndrome known 
as Long COVID. 
In 2024, the National Academies of Sciences, Engineering and Medicine 
defined Long COVID as a chronic, infection-associated condition that 
persists for at least three months post-infection, presenting as continuous, 
relapsing, remitting or progressive disease affecting one or more organ 
systems.2 Symptoms such as fatigue, brain fog and cognitive impairment 
can significantly impact daily life, with more than 26 percent of individuals 
reporting serious limitations in their ability to carry out everyday activities.3 
At Moderna, we are dedicated to raising awareness of Long COVID’s far-
reaching effects, as millions continue to suffer its long-term consequences.4 
In 2024, we engaged with advocacy groups, community health organizations, 
employers and the media to advocate for support and identify gaps in 
understanding and accommodations for patients. Patients often feel 
unheard and left behind as they navigate life with debilitating symptoms and 
limitations.5 Rachel, a wife and mother of three, experiences this struggle. 
Diagnosed with Long COVID in May 2021, she has been unable to work or 
fully engage in daily life due to extreme fatigue, chronic pain and nausea. 
Beyond the human toll, the global economic burden of Long COVID is 
staggering. Millions of people have been kept out of work, which is estimated 
to have an annual economic impact of approximately $1 trillion.6 Through 
ongoing partnerships across the healthcare ecosystem, we aim to better 
understand and address these impacts to support patients.
There was a ‘before Rachel,’ before 
COVID, and an ‘after Rachel,’ after I got 
sick. They’re not the same person.”

Advancing oncology through state-of-the-art 
manufacturing
Moderna is building a state-of-the-art manufacturing facility in 
Marlborough, MA, dedicated to producing our investigational 
individualized neoantigen therapy (INT), mRNA-4157. This facility reflects 
our commitment to advancing our oncology portfolio as we continue to 
explore the potential of INT across multiple tumor types. 
In 2024, together with our partner Merck, we advanced the development 
of investigational INT by initiating a pivotal Phase 3 trial evaluating its 
combination with KEYTRUDA® as adjuvant treatment in certain types 
of non-small cell lung cancer (NSCLC). Previously in 2023, Merck and 
Moderna initiated Phase 3 trials evaluating INT in combination with 
KEYTRUDA as an adjuvant treatment in patients with resected high-risk 
(Stage IIB-IV) melanoma and NSCLC. Additionally, we launched clinical 
trials across multiple tumor types, including renal cell carcinoma in 2024. 
Once operational, the Marlborough facility will support clinical supply 
for these trials and enable the potential commercial launch of INT, 
underscoring our commitment to developing transformative therapies  
to better the lives of patients around the globe. 
Robotics
At Moderna, we recognize that robotics and automation are essential 
drivers of innovation, efficiency, and scalability. By integrating advanced 
robotics into our operations, we are optimizing workflows and enhancing 
consistency across every stage of development—from preclinical 
research to commercial production.
In 2024, we deployed multiple Autonomous Mobile Robots (AMRs) and 
Integrated Robotics Workcells to address a variety of needs, including 
transferring materials between buildings for manufacturing and quality 
control, transporting samples and in-process materials between 
laboratories, and moving inventory within our international drug product 
manufacturing and distribution centers. These robotics systems have 
significantly boosted efficiency, streamlined lab operations, and ensured 
more reliable processes with consistent timing. Beyond these examples, 
we have also introduced advanced robotics for high-throughput 
screening, automated quality control, and individualized neoantigen 
therapy manufacturing—further enhancing accuracy and enabling critical 
workflows that support the high standards of our operations.

Our commitment to advancing robotics and automation is about 
more than just efficiency—it’s about empowering our teams to bring 
transformative medicines to patients with precision and reliability. By 
focusing on deploying advanced technologies, we are preparing for the 
future and helping to ensure our ability to meet evolving health challenges 
with innovative solutions.
A global network of manufacturing 
Moderna achieved significant milestones in expanding our global network of 
mRNA manufacturing sites in 2024, underscoring our commitment to public 
health and pandemic preparedness.
In Melbourne, Australia, we celebrated the opening of the Moderna 
Technology Center (MTC-M), the nation’s first and only commercial-scale 
mRNA vaccine manufacturing facility. This state-of-the-art site enhances 
Australia’s ability to produce and distribute mRNA vaccines domestically, 
reducing dependence on global supply chains.
In Laval, Quebec, our Canadian manufacturing facility was granted a 
Drug Establishment License (DEL) by Health Canada, a critical milestone 
enabling the site to become fully operational. With this designation, we are 
now closer to ensuring a reliable, onshore supply of mRNA vaccines for 
Canada, strengthening the nation’s resilience against future public health 
emergencies.
Additionally, our UK site at the Harwell Science and Innovation Campus 
continues to progress. Since breaking ground in April 2023, the Moderna 
Innovation and Technology Center (MITC) is nearing a pivotal stage of 
development, aiming for full operational readiness in 2025.
Together, these sites form a decentralized production network designed 
to ensure that lifesaving mRNA vaccines can be delivered quickly and 
efficiently. Through our agreements with the governments in these 
countries, Moderna is not only advancing pandemic readiness but also 
fostering innovation, economic growth and local talent development 
worldwide.

A Letter from 
Our CEO

Since our beginnings, we’ve leveraged the power of machine learning 
and technology to develop transformative mRNA medicines. Recognizing 
early on that the future of medicine would rely on groundbreaking science 
and cutting-edge technology, we built a robust tech stack and adopted a 
cloud-native approach. These foundations positioned us to fully integrate 
next-generation AI tools, which are critical to scaling our operations and 
maximizing patient impact.
In April 2024, we announced our ongoing collaboration with OpenAI to 
deploy ChatGPT Enterprise across the company. By the end of the year, 
more than 4,500 of our employees were actively engaged with AI tools 
each month. This widespread adoption unlocked new efficiencies and 
enabled novel solutions across our organization—spanning research, 
development, manufacturing and more—embedding AI as a cornerstone 
of our operations.
We are well-positioned to continue leading the biopharmaceutical 
industry in AI-driven innovation. Building on the foundations we’ve laid and 
the successes of 2024, AI will remain a driving force in scaling our impact, 
enabling agility, and delivering on our Mission for patients.
AI in action 
Legal: Moderna’s Legal team led the development and rollout of tailored 
GPTs, including Contract Companion GPT, which provides teams across 
the Company with clear, concise contract summaries, streamlining 
decision-making. Another custom solution, Policy Bot GPT, empowers 
employees with instant answers to internal policy questions, eliminating 
the need to sift through hundreds of documents, so teams can focus on 
more strategic work.
Human Resources: Moderna introduced the Benefits GPT, a tailored 
AI solution designed to streamline access to benefits information for 
employees across the U.S. and select international locations. This 
innovative tool provides employees with instant, accurate guidance on 
country-specific and global benefits, reducing complexity and saving time 
on important decisions impacting employee health and wellness.
Development: To support the clinical team in developing and refining 
responses to health authorities, Moderna introduced Regbot 3.0, an 
advanced generative AI solution. Regbot 3.0 streamlines the drafting 
process for complex regulatory queries by leveraging historical data and 
previous responses to similar questions. The AI-generated drafts are 
then reviewed and validated by our team to ensure accuracy and full 
compliance with regulatory standards, cutting review and response times 
significantly in an effort to potentially reach patients faster.
Operations: The Odyssey Transition Assistant GPT was a purpose-
built tool designed to accelerate SAP end-user support during and 
after the SAP S/4 implementation, part of a broader transformation to 
simplify, standardize and modernize processes across finance and CMC 
operations. This tool provided immediate, accurate answers from tailored 
documentation across multiple key knowledge areas: GSAP access, 
training, cross-references, master data and security roles. By reducing 
delays, ensuring accuracy and guiding users directly to solutions, it 
helped improve operational efficiency and minimize downtime during 
the transition.

Focusing on belonging 
At Moderna, we lead with belonging. We share a united belief in our 
Mission and culture, enabling employees to bring their authentic selves to 
work. We believe that a strong sense of belonging empowers our teams 
to perform at their best, thrive and contribute meaningfully to our collective 
success. As of December 31, 2024, 49 percent of our workforce and

Additionally, BioSpace named Moderna the number one large employer in 
its Best Places to Work report for the fourth year in a row and for the first 
time, we were ranked ninth on the 2024 LinkedIn Top Companies list in the 
United States. We were also recognized by the Human Rights Campaign 
Foundation as an Equality 100 company for the second time in January 
2025 and acknowledged by Disability:IN as a top-scoring company on the 
Disability Equality Index—a proud moment for Moderna as we continued 
to build a culture of belonging.

A Letter from 
Our CEO

We care deeply about our patients, our employees, the environment 
and our communities, and we recognize that our responsibility to 
create sustainable long-term value for them is critical to our Mission. 
We underscored our commitment to responsible business through the 
publication of our third annual ESG Report in June 2024. 
Prioritizing inclusive research 
In 2024, we remained steadfast in our commitment to inclusive research. 
We realize we cannot maximize the potential of mRNA without ensuring 
that access to these medicines is inclusive of all populations. Recognizing 
the importance of diversity for scientific excellence, we design our 
clinical trials to reflect the global community, particularly those medically 
underserved communities and underrepresented populations. We 
continued to include broad demographic objectives across our clinical 
trials, and we achieved 40 percent Global Ethnic Majority enrollment in U.S. 
infectious disease trials. 
To sustain our drive toward inclusive research, we concentrate our efforts 
around three pillars: increasing awareness, bringing trials into communities, 
and providing flexible participation options. This approach has led to 
increased enrollment, retention and participant satisfaction. 
mRNA Access 
Our mRNA Access program offers researchers use of Moderna’s mRNA 
technology to explore new vaccines against emerging or neglected 
infectious diseases. The program opens our preclinical manufacturing 
capabilities and research and development expertise to global partners, 
to promote a collaborative approach to exploring the possibility of mRNA 
to tackle the world’s greatest global public health threats. In 2024, we 
continued collaborations with 18 institutions around the globe.

Moderna Charitable Foundation 
The Moderna Charitable Foundation continued to make a positive impact 
in our communities locally and globally. Through philanthropic giving, 
employee gift matching and disaster humanitarian relief, the Moderna 
Foundation supported nonprofit organizations with $6.9 million in grants, 
donations and matching gifts in 2024. Partnerships with organizations 
such as Amref Health Africa, Boston Community Pediatrics, Seed Global 
Health and Year Up United, further advance the Foundation’s mission to 
promote public health, advance scientific education and advocate for 
diversity and inclusion. 
Giving back to the community 
Our commitment to serving the communities where we live and work 
has always been part of our identity. Each year between Giving Tuesday 
and International Volunteer Day, we organize a company-wide Volunteer 
Week. 2024 marked our sixth annual Volunteer Week, and hundreds of 
Moderna team members participated in organized activities across twenty 
locations to make a substantial impact with more than thirty community 
partners around the world. 
All our team members receive eight hours of paid time off each year 
to dedicate toward volunteering, and our Dollars for Doers program 
matches additional volunteer time at a specific hourly rate. Additionally, the 
Moderna Foundation matches monetary donations that employees have 
made to qualified charitable organizations. In 2024, our collective efforts 
supported more than 2,800 nonprofits around the world, with 76 percent 
of our workforce engaging in giving, volunteering, or both. 
Protecting the environment 
We recognize our responsibility to grow in a way that protects the planet 
and minimizes our environmental impact. Moderna is committed to 
reducing absolute Scope 1 and Scope 2 greenhouse gas (GHG) emissions 
by 90 percent by 2030 from a 2021 base year, and to achieving net-zero 
GHG emissions across Scopes 1, 2 and 3 by 2045. 
A cornerstone of our sustainability strategy is embedding sustainability-
by-design principles into our new facilities. In February 2024, we 
commenced operations at our Moderna Science Center in Cambridge, 
Massachusetts. This purpose-built headquarters supports the next 
chapter of our innovation journey and features state-of-the-art sustainable 
design elements, including geothermal heating and cooling, rooftop solar, 
an exhaust air heat pump and ultra-efficient building systems. We are 
advancing sustainability in our global network of mRNA manufacturing sites 
in the UK, Canada and Australia, which are designed with technologies 
such as heat pumps to significantly reduce fossil fuel consumption.
As we look ahead to 2025, we are focused on further integrating climate 
risk management into our operations and enhancing programs to address 
energy use, emissions and waste. This reinforces our dedication to 
environmental stewardship as we strive to create a lasting positive impact 
on human health.

SUMMARY OF THE MATERIAL RISKS ASSOCIATED WITH OUR BUSINESS
Our business is subject to numerous risks and uncertainties that you should be aware of before making an investment decision, 
including those highlighted in the section entitled “Risk Factors.” These risks include, but are not limited to, the following:
•
Uncertainty and evolving dynamics in the markets for COVID and RSV vaccines, and respiratory vaccines more generally, 
have in the past impacted and are likely to continue to impact our financial results;
•
We have experienced commercial challenges and are likely to experience additional challenges in the future;
•
The vaccine market, and pharmaceutical market more generally, is intensely competitive, and we may not compete 
effectively in the market for existing or new products, treatment methods or technologies;
•
We may be unsuccessful in executing our cost efficiency and portfolio prioritization efforts;
•
We may be unsuccessful or delayed in updating our COVID vaccine to protect against future variants of the SARS-CoV-2 
virus;
•
The commercial success of our products depends on the degree of market acceptance by physicians, patients, third-party 
payors and others in the medical community;
•
Sales of pharmaceutical products depend on the availability and extent of reimbursement from third-party payors, and we 
may be adversely impacted by changes to such reimbursement policies or rules;
•
The market opportunities for our products and product candidates may be smaller than we believe, or we may be unable to 
successfully identify clinical trial participants;
•
If we cannot obtain, or are delayed in obtaining, regulatory approvals and advisory committee recommendations, we will be 
unable to commercialize, or will be delayed in commercializing, our product candidates;
•
Clinical development is lengthy and uncertain, and our clinical programs may be delayed or terminated, or may be more 
costly to conduct than we anticipate;
•
Our products are, and any future products will be, subject to regulatory scrutiny;
•
We or our third-party manufacturers may encounter difficulties in manufacturing, product release, shelf life, testing, storage, 
supply chain management or shipping for any of our products;
•
As we grow as a commercial company and our drug development pipeline increases and matures, the increased demand for 
clinical and commercial supplies from our facilities and third parties may impact our ability to operate. We rely on third-party 
service providers, all of whom have inherent risks in their operations;
•
We are subject to operational risks associated with the physical and digital infrastructure at our manufacturing facilities and 
those of our external service providers;
•
Our individualized neoantigen therapy (INT) product candidates are uniquely manufactured for each patient using a novel, 
complex manufacturing process and we may encounter difficulties in production;
•
We are dependent on single-source suppliers for some of the components and materials used in, and the manufacturing 
processes required to develop and commercialize, our products and product candidates;
•
We have entered, and may enter into, strategic alliances with third parties for product development and commercialization. If 
these alliances are unsuccessful, our business could be adversely affected;
•
We may seek to establish additional strategic alliances and, if we are unable to establish them on commercially reasonable 
terms, we may have to alter our development and commercialization plans. Certain of our strategic alliance agreements may 
restrict our ability to develop certain products;
•
We may be unable to obtain and enforce patent protection for our discoveries and the intellectual property rights therein, or 
protect the confidentiality of our trade secrets;
•
Uncertainty over intellectual property in the pharmaceutical and biotechnology industry has been the source of litigation and 
other disputes, which is inherently costly and unpredictable and can have adverse financial and freedom-to-operate 
consequences;
•
We incurred net losses in 2024 and 2023, and expect to incur additional losses in the future; we have a limited history of 
recognizing revenue from product sales and may note achieve long-term sustainable profitability;
•
Our quarterly and annual operating results may fluctuate. As a result, we may fail to meet or exceed the expectations of 
research analysts or investors, which could cause our stock price to decline;
•
We may encounter difficulties in managing the development and expansion of our company;
•
Our internal computer systems and physical premises, or those of third parties with which we share sensitive data or 
information, may fail or suffer security breaches, including from cybersecurity incidents, which could materially disrupt our 
product development programs and manufacturing operations; and
•
The price of our common stock has been volatile, which could result in substantial losses for shareholders.
You should consider carefully the risks and uncertainties described below, in the section entitled “Risk Factors” and the other 
information contained in this Annual Report on Form 10-K, including our consolidated financial statements and the related notes,

PART I
Item 1. Business
Moderna is a leader in the creation of the field of messenger RNA (mRNA) medicine. Through the advancement of mRNA 
technology, we are reimagining how medicines are made and transforming how we treat and prevent disease for everyone. By working 
at the intersection of science, technology and health for more than a decade, we have developed medicines at unprecedented speed and 
efficiency, including one of the earliest and most effective COVID vaccines.
Our mRNA platform has enabled the development of medicines across four franchises: respiratory virus vaccines, latent and other 
virus vaccines, oncology therapeutics and rare disease therapeutics. With a unique culture and a global team driven by the Moderna 
values and mindsets to responsibly change the future of human health, we strive to deliver the greatest possible impact to people 
through mRNA medicines.
Our first commercial product, Spikevax (our COVID vaccine), has helped hundreds of millions of people worldwide combat 
COVID-19. SARS-CoV-2, the virus that causes COVID-19, continues to evolve, and in 2023, the COVID vaccine market shifted from 
a pandemic to an endemic, seasonal commercial market. In 2024, we became a multi-product company with the approval of our 
second commercial product, mRESVIA, our mRNA respiratory syncytial virus (RSV) vaccine for older adults. In 2024, we achieved 
net product sales of $3.1 billion, largely from sales of Spikevax.  
Beyond our commercial products, we continue to demonstrate the potential of our platform technology. In 2024, we shared four 
positive Phase 3 data readouts across our respiratory portfolio—for our next-generation COVID vaccine, our RSV vaccine for high-
risk adults aged 18 to 59, our seasonal flu+COVID combination vaccine and our seasonal flu vaccine. In the area of oncology 
therapeutics, we continue to demonstrate the potential clinical benefit of our individualized neoantigen therapy (INT) (mRNA-4157), 
which is being developed in collaboration with Merck. We and Merck have rapidly expanded clinical studies to several tumor types 
and completed enrollment of the Phase 3 clinical trial for adjuvant melanoma in 2024. Additionally, in 2024, we also took steps to 
move two of our rare disease therapeutics programs—targeting propionic acidemia (PA) and methylmalonic acidemia (MMA)—
toward registrational trials. We also achieved milestones in our latent and other vaccines franchise, including the initiation of a Phase 3 
study of our norovirus vaccine.  
Our success in research and development is a testament to our platform. Moving forward, we are taking a paced approach to our 
research and development investment. We entered 2025 with a focus on a prioritized portfolio addressing our four franchises where 
there is unmet need.
THE mRNA OPPORTUNITY
mRNA, the software of life
mRNA transfers the information stored in our genes to the cellular machinery that makes all the proteins required for life. Our genes 
are stored as sequences of DNA which contain the instructions to make specific proteins. DNA serves as a hard drive, safely storing 
these instructions in the cell’s nucleus until they are needed by the cell.
When a cell needs to produce a protein, the instructions to make that protein are copied from the DNA to mRNA, which serves as the 
template for protein production. Each mRNA molecule contains the instructions to produce a specific protein with a distinct function 
in the body. mRNA transmits those instructions to cellular machinery, called ribosomes, that make copies of the required protein.
We see mRNA functioning as the “software of life.” Every cell uses mRNA to provide real time instructions to make the proteins 
necessary to drive all aspects of biology, including in human health and disease. This was codified as the central dogma of molecular 
biology over 60 years ago, and is exemplified in the schematic below.

The structure of mRNA 
mRNA is a linear polymer comprising four monomers called nucleotides: adenosine (A), guanosine (G), cytosine (C) and uridine (U). 
Within the region of the molecule that codes for a protein (the coding region), the sequence of these four nucleotides forms a language 
made up of three-letter words called codons. The first codon, or start codon (AUG), signals where the ribosome should start protein 
synthesis. To know what protein to make, the ribosome then progresses along the mRNA one codon at a time, appending the 
appropriate amino acid to the growing protein. To end protein synthesis, three different codons (UAA, UAG, and UGA) serve as stop 
signals, telling the ribosome where to terminate protein synthesis. In total, there are 64 potential codons, but only 20 amino acids that 
are used to build proteins; therefore, multiple codons can encode for the same amino acid.
The process of protein production is called translation because the ribosome is reading in one language (a sequence of codons) and 
outputting in another language (a sequence of amino acids). The coding region is analogous to a sentence in English. Much like a start 
codon, a capitalized word can indicate the start of a sentence. Codons within the coding region resemble groups of letters representing 
words. The end of the sentence is signaled by a period in English, or a stop codon for mRNA.
In every cell, hundreds of thousands of mRNAs make hundreds of millions of proteins every day. A typical protein contains 200-600 
amino acids; therefore, a typical mRNA coding region ranges from 600-1,800 nucleotides. In addition to the coding region, mRNAs 
contain four other key features: (1) the 5’ untranslated region (5’-UTR); (2) the 3’ untranslated region (3’-UTR); (3) the 5’ cap; and 
(4) a 3’ polyadenosine (poly-A) tail. The sequence of nucleotides in the 5’-UTR influences how efficiently the ribosome initiates 
protein synthesis, whereas the sequence of nucleotides in the 3’-UTR contains information about which cell types should translate that 
mRNA and how long the mRNA should last. The 5’ cap and 3’ poly-A tail enhance ribosome engagement and protect the mRNA from 
attack by intracellular enzymes that digest mRNA from its ends.

The intrinsic advantages of using mRNA as a medicine
mRNA possesses inherent characteristics that we believe position it to have a profound impact on human health:
•
mRNA is used by every cell to produce all proteins: mRNA is used to make every type of protein, including secreted, 
membrane and intracellular proteins, in varying quantities over time, in different locations and in various combinations. 
Given the universal role of mRNA in protein production, we believe that mRNA medicines could have broad applicability 
across human disease.
•
Making proteins inside one’s own cells mimics human biology: Tailored mRNA can be sent into cells to instruct them to 
produce specific protein therapeutics or vaccine antigens and provides certain advantages over traditional approaches to 
medicine, where a protein or chemical is introduced to the body.
•
mRNA has a simple and flexible chemical structure: Each mRNA molecule comprises four chemically similar nucleotides 
to encode proteins made from up to 20 chemically different amino acids. To make the full diversity of possible proteins, only 
simple sequence changes are required in mRNA, instead of starting from scratch for each new vaccine or therapy.
•
mRNA has classic pharmacologic features: mRNA possesses many of the attractive pharmacologic features of most 
modern medicines, including reproducible activity, predictable potency and well-behaved dose dependency; mRNA also 
provides the ability to adjust dosing based on an individual patient’s needs, including stopping or lowering the dose, to seek 
to promote safety and tolerability.
Our success in developing, manufacturing and commercializing vaccines against COVID-19 and RSV demonstrates the potential of 
mRNA medicines to help people and patients in far-reaching ways that could exceed the impact of traditional approaches to medicine.
We believe that the main advantages of mRNA as compared to traditional medicine are: 
1.
mRNA could create an unprecedented abundance and diversity of medicines. mRNA’s breadth of applicability has the 
potential to create an extraordinary number of new mRNA medicines that are currently beyond the reach of recombinant 
protein technology.
2.
Advances in the development of our mRNA medicines reduce risks across our portfolio. mRNA medicines share 
fundamental features that can be leveraged across our portfolio. We believe that once safety and proof of protein production 
has been established in one program, the technology and biology risks of related programs that use similar mRNA 
technologies, delivery technologies and manufacturing processes will decrease significantly.  
3.
mRNA technology can accelerate discovery and development. The software-like features of mRNA enable rapid in silico 
design and the use of automated high-throughput synthesis processes that permit discovery to proceed in parallel rather than 
sequentially. We believe these mRNA features can also accelerate drug development by allowing the use of shared 
manufacturing processes and infrastructure.
4.
The ability to leverage shared processes and infrastructure can drive significant capital efficiency over time. We 
believe the manufacturing requirements of different mRNA medicines are similar and that at commercial scale, a portfolio of 
mRNA medicines will benefit from shared capital expenditures.
OUR STRATEGY
We believe that the development of mRNA medicines represents a significant breakthrough for patients, our industry and human 
health globally. Our success in developing one of the earliest and most effective COVID vaccines, at unprecedented speed and 
efficiency, demonstrates the promise of mRNA medicine. Our COVID vaccine has helped hundreds of millions of people worldwide 
combat COVID-19. Beyond COVID, our platform continues to be highly productive, with our RSV vaccine representing our second 
commercial product and eleven programs in late-stage development. 
We are currently focused on three strategic priorities: 
1.
Driving use of Spikevax and mRESVIA. Spikevax and mRESVIA are the foundation of our respiratory vaccine portfolio 
and we expect to participate in the full contracting season in the United States for both in 2025 for the first time. We will 
continue to work with all market channels to maximize the availability of Spikevax. Internationally, we plan to bring 
manufacturing plants online in Australia, Canada and the United Kingdom (UK) in 2025, subject to execution of 
manufacturing plant licensures. With a full season of RSV contracting in 2025, our goal is to increase mRESVIA’s market 
share in the United States and market access globally.
2.
Focusing on ten product approvals over the next three years to drive sales growth. Our prioritized programs span our 
four franchises: respiratory, latent and other virus, oncology and rare diseases. We expect execution of this priority to drive

sales growth and fund our next wave of research and development investment. For nine of these programs, we have near-term 
milestones, including up to three potential 2025 approvals for our next-generation COVID vaccine, our RSV vaccine for 
high-risk adults aged 18 to 59, and our flu+COVID combination vaccine for adults 50 years and older. We also anticipate up 
to six upcoming registrational data readouts for our cytomegalovirus (CMV), seasonal flu, norovirus, INT for adjuvant 
melanoma, PA and MMA product candidates.
3.
Delivering cost efficiency across the business. We plan to continue improving efficiency by further reducing our research 
and development and selling, general and administrative expenses in 2025. By 2027, we expect to decrease annual research 
and development expenses by approximately $1.0 billion compared to 2024. On cost of sales, we will work to continue to 
drive efficiency through manufacturing productivity improvements to achieve operating leverage.
OUR PLATFORM
Overview of our platform
Our mRNA “platform” refers to our accumulated knowledge and capabilities in basic and applied sciences. Our platform incorporates 
advances across three key components—mRNA, delivery and the manufacturing process— to advance our medicines. We integrate 
these components and combine different versions of mRNA delivery and process into each of our medicines. 
Our platform: mRNA science advancements
We continue to invest in both basic and applied research, seeking to advance both the state of our technology and the state of the 
scientific community’s understanding of mRNA. Examples of advances in mRNA science that combine nucleotide chemistry, 
sequence engineering and targeting elements are described below.
mRNA chemistry: Modified nucleotides to mitigate immune system activation: The innate immune system has evolved to protect 
cells from foreign RNA, such as viral RNA, by inducing inflammation and suppressing mRNA translation once detected. Many cells 
surveil their environment through sensors called toll-like-receptors (TLRs). These include types that are activated by the presence of 
double-stranded RNA (TLR3) or uridine containing RNA fragments (TLR7, TLR8). Additionally, all cells have cytosolic double-
stranded RNA, sensors, including retinoic acid inducible gene-I (RIG-I) that are sensitive to foreign RNA inside the cell.
The immune and cellular response to mRNA is complex, context specific, and often linked to the sensing of uridine. To minimize 
undesired immune responses to our potential mRNA medicines, our platform employs chemically-modified uridine nucleotides to 
minimize recognition by both immune cell sensors such as TLR3/7/8, and broadly-distributed cytosolic receptors such as RIG-I. 
mRNA sequence engineering: Maximizing protein expression: mRNA exists transiently in the cytoplasm, during which time it can 
be translated into thousands of proteins before eventually being degraded. Our platform applies bioinformatic, biochemical, and 
biological screening capabilities, most of which have been invented internally that aim to optimize the amount of protein produced per 
mRNA. We have identified proprietary sequences for the 5’-UTR that have been observed to increase the likelihood that a ribosome 
bound to the 5’-end of the mRNA transcript will find the desired start codon and reliably initiate translation of the coding region. We 
additionally design the nucleotide sequence of the coding region to maximize its successful translation into protein. 
Targeting elements: Enabling tissue-targeted translation: All nucleated cells in the body are capable of translating mRNA, 
resulting in pharmacologic activity in any cell in which mRNA is delivered and translated. To minimize or prevent potential off-target 
effects, our platform employs technologies that regulate mRNA translation in select cell types. Cells often contain short RNA 
sequences, called microRNAs or miRNAs, that bind to mRNA to regulate protein translation at the mRNA level. Different cell types 
have different concentrations of specific microRNAs, in effect giving cells a microRNA signature. microRNA binding directly to 
mRNA effectively silences or reduces mRNA translation and promotes mRNA degradation. We design microRNA binding sites into 
the 3’-UTR of our potential mRNA medicines so that if our mRNA is delivered to cells with such microRNAs, it will be minimally 
translated and rapidly degraded.
Our platform: Delivery science
Our mRNA can, in specific instances, be delivered by direct injection to a tissue in a simple saline formulation without lipid 
nanoparticles (LNPs) to locally produce small amounts of pharmacologically active protein. However, the blood and interstitial fluids 
in humans contain significant RNA degrading enzymes that rapidly degrade any extracellular mRNA and prevent broader distribution 
without LNPs. Additionally, cell membranes tend to act as a significant barrier to entry of large, negatively-charged molecules such as 
mRNA. We have therefore invested heavily in delivery science and have developed LNP technologies to enable delivery of larger 
quantities of mRNA to target tissues.
Table of Contents
10

LNPs are generally composed of four components: an amino lipid, a phospholipid, cholesterol, and a pegylated-lipid (PEG-lipid). 
Each component, as well as the overall composition, or mix of components, contributes to the properties of each LNP system. LNPs 
containing mRNA injected into the body rapidly bind proteins that can drive uptake of LNPs into cells. Once internalized in 
endosomes within cells, the LNPs are designed to escape the endosome and release their mRNA cargo into the cell cytoplasm, where 
the mRNA can be translated to make a protein and have the desired therapeutic effect. Any mRNA and LNP components that do not 
escape the endosome are typically delivered to lysosomes where they are degraded by the natural process of cellular digestion. 
Examples of tools we developed by using our platform include proprietary LNP formulations that address the steps of mRNA 
delivery, including cell uptake, endosomal escape, and subsequent lipid metabolism, and for avoidance of counterproductive 
interactions with the immune system. 
Chemistry: Novel lipid chemistry to potentially improve safety and tolerability: Our proprietary LNP systems are designed to be 
highly tolerated and minimize any LNP vehicle-related toxicities with repeat administration in vivo. To overcome limitations of 
previous LNP formulations, we have engineered amino lipids to avoid the immune system and to be rapidly biodegradable relative to 
prior lipids. 
Composition: Proprietary LNPs enhance delivery efficiency: Our platform includes extensive in-house expertise in medicinal 
chemistry, which we have applied to design large libraries of novel lipids. Using these libraries in combination with our discovery 
biology capabilities, we have conducted high throughput screens for desired LNP properties and believe that we have made 
fundamental discoveries in preclinical studies about the relationships between structural motifs of lipids and LNP performance for 
protein expression. 
Surface properties: Novel LNP design to avoid immune recognition: We have designed our proprietary LNP systems for sustained 
pharmacology upon repeat dosing by eliminating or altering features that activate the immune system. These are based on insights into 
the surface properties of LNPs. Upon repeated dosing, surface features on traditional LNPs such as amino lipids, phospholipids, and 
PEG-lipids, can be recognized by the immune system, leading to rapid clearance from the bloodstream, a decrease in potency upon 
repeat dosing, and an increase in inflammation. Based on our insights into these mechanisms, we have engineered our LNP systems to 
reduce or eliminate undesirable surface features. In clinical studies for our systemic therapeutic product candidates that use our novel 
LNP systems, we have been able to repeat dose with negligible or undetectable loss in potency, liver damage, and immune system 
activation.
Our platform: Manufacturing process science
We invest significantly in manufacturing process science to impart more potent features to our mRNA and LNPs, and to invent the 
technological capabilities necessary to manufacture our mRNA medicines at scales ranging from micrograms to kilograms, as well as 
achieve pharmaceutical properties such as solubility and shelf life. We view developing these goals of manufacturing and 
pharmaceutical properties as appropriate for each program, based on its stage of development.
mRNA manufacturing process: Improving pharmacology: Our platform creates mRNA using a cell-free approach called in vitro 
transcription in which an RNA polymerase enzyme binds to and transcribes a DNA template, adding the nucleotides encoded by the 
DNA to the growing RNA strand. Following transcription, we employ proprietary purification techniques to ensure that our mRNA is 
free from undesired synthesis components and impurities that could activate the immune system in an indiscriminate manner. 
Applying our understanding of the basic science underlying each step in the manufacturing process, we have designed proprietary 
manufacturing processes to impart desirable pharmacologic features, for example increasing potency in a vaccine. 
LNP manufacturing process: Improving pharmacology: Our platform technology includes synthetic processes to produce LNPs. 
Traditionally LNPs are assembled by dissolving the four molecular components, amino lipid, phospholipid, cholesterol, and PEG-
lipid, in ethanol and then mixing this with mRNA in an aqueous buffer. The resulting mixture is then purified to isolate LNPs from 
impurities. Such impurities include molecular components that have not been incorporated into particles, un-encapsulated mRNA that 
could activate the immune system, and particles outside of the desired size range. Going beyond optimization of traditional 
manufacturing processes, we have invested in understanding and measuring the various biochemical and physical interactions during 
LNP assembly and purification. We have additionally developed state-of-the-art analytical techniques necessary to characterize our 
LNPs and biological systems to analyze their in vitro and in vivo performance. With these insights, we have identified manufacturing 
process parameters that drive LNP performance, for example, the potency in a secreted therapeutic setting. These insights have 
allowed us to make significant improvements in the efficiency of our processing and the potency of our LNPs.

Harnessing the power of mRNA through modalities 
Within our platform, we invest in science to invent novel ways to deliver mRNA into various cell types. Each novel delivery system is 
a new application, called a “modality.” While the programs within a modality may target diverse diseases, they share similar mRNA 
characteristics and manufacturing processes to achieve shared product features.  
We believe that the high technological correlation within a modality allows us to rapidly accelerate the expansion of programs within 
that modality based on learnings from the earlier programs, while the lower technology correlation between modalities allows us to 
compartmentalize the technology risks. Additionally, because programs within a modality pursue diverse diseases, they often have 
uncorrelated biology risk. New modalities and product candidates can create a network effect by helping us gain additional insight into 
the other programs in our pipeline. 
Although developing a new modality is difficult, time-consuming and expensive, we believe our experience and technology provide us 
with unique advantages in the development of mRNA medicines. Over the last decade, we have developed a number of modalities, 
each with one or many product candidates in the clinic. We believe that our ongoing investments in our platform will lead to the 
identification of additional modalities and expand the utility of our existing modalities and the diversity of our pipeline. 
OUR PIPELINE
Over the last decade, we have advanced in parallel a diverse development pipeline that currently consists of 44 therapeutic and vaccine 
programs, eleven of which are in late-stage development. The scope of our pipeline reflects the breadth of biology addressable using 
mRNA technology, and spans four franchises: respiratory virus vaccines, latent and other vaccines, oncology therapeutics, and rare 
disease therapeutics. 
Our selection process for advancing new product candidates reflects both program-specific and portfolio-wide considerations. 
Program-specific criteria include, among other relevant factors, the severity of the unmet medical need, the biology risk of our chosen 
target or disease, the feasibility of clinical development, the costs of development and the commercial opportunity. Portfolio-wide 
considerations include the ability to demonstrate technical success for our platform components within a modality, thereby increasing 
the probability of success and learnings for subsequent programs. We are currently focusing our efforts on delivering up to ten 
prioritized products over the next three years to drive sales growth and fund the next wave of research and development investment.

RESPIRATORY FRANCHISE 
We have two commercial respiratory virus vaccines—Spikevax (our COVID vaccine) and mRESVIA (our RSV vaccine for older 
adults). Additionally, we have achieved four positive Phase 3 data readouts for our next-generation COVID vaccine (mRNA-1283), 
our RSV vaccine for high-risk adults aged 18 to 59 (mRNA-1345), our seasonal flu+COVID vaccine (mRNA-1083), and our seasonal 
flu vaccine (mRNA-1010). We have a total of 15 respiratory programs in our current portfolio, summarized below.
COVID vaccines (Spikevax/mRNA-1273, next-generation mRNA-1283) 
Spikevax is approved for use in jurisdictions globally. COVID-19 is caused by the SARS-CoV-2 virus that was first identified in 
humans in 2019, driving a global pandemic resulting in millions of deaths. The risk of mortality increases with age and the risk of 
severe disease and mortality increases for persons with certain pre-existing diseases or comorbid conditions, such as cardiovascular 
disease, diabetes, chronic lung disease and obesity. 
As the SARS-CoV-2 virus continues to evolve, Spikevax continues to be a key tool in fighting COVID-19. As part of our strategy to 
continue to combat COVID-19, we develop and assess variant-specific versions of our COVID vaccine. In August and September 
2024, we received regulatory approvals in major markets for our updated COVID vaccine, targeting the JN.1 (mRNA-1273.167) and 
KP.2 (mRNA-1273.712) subvariants of SARS-CoV-2, based on the new variant composition requests from different public health 
bodies. We developed JN.1 and KP.2 formulations of mRNA-1273 in accordance with regulatory guidance, with the goal of 
broadening vaccine-induced immunity and providing protection against circulating SARS-CoV-2 variants. We have also observed 
preliminary clinical trial data showing that these vaccines generate a robust immune response (cross-neutralization) against currently 
circulating variants of SARS-CoV-2.
The FDA has approved Spikevax for individuals 12 years and older, and granted Emergency Use Authorization for individuals aged 
six months through 11 years. Spikevax has also been authorized for individuals six months and older in other key markets, including 
the European Union (EU), Canada and Japan.
Forward-looking references to our COVID vaccine in this Annual Report on Form 10-K may include future modifications to 
mRNA-1273 or other product candidates that are designed to provide protection against variants of the SARS-CoV-2 virus. 
In addition to Spikevax, we have advanced other COVID vaccine candidates into the clinic as part of our effort to fight the evolving 
SARS-CoV-2 virus. In June 2024, we announced positive Phase 3 efficacy data for our next-generation COVID vaccine, 
mRNA-1283. In September 2024, we shared additional data for mRNA-1283, which included non-inferior relative vaccine efficacy 
(rVE) compared to Spikevax. We filed for FDA approval for mRNA-1283 in 2024 using a priority review voucher, and have been 
assigned a Prescription Drug User Fee Act (PDUFA) goal date of May 31, 2025. Our goal with mRNA-1283 is to facilitate easier 
distribution and administration by healthcare providers, as it is designed to have enhanced stability in refrigerated conditions and 
packaged in pre-filled syringes. 
As SARS-CoV-2 evolves, we continue to perform continuous epidemiological monitoring, genomic surveillance and risk assessments 
of variants of concern to determine which new variants may have the ability to circumvent immunity provided by currently approved 
COVID vaccines. For variants that appear to be growing in circulation and have evolved the ability to evade immunity, we proactively 
develop new product candidates. We have taken several of these candidates to clinical trials, and our monitoring activities allow for 
expedited delivery of new vaccines in the event that regulatory agencies request specific vaccine composition updates to address 
public health needs.
RSV vaccine (mRESVIA/mRNA-1345)
Respiratory syncytial virus (RSV) is one of the most common causes of lower respiratory disease in children under the age of five and 
in older adults. Populations that are especially vulnerable to developing severe RSV infections include infants, young children, 
children and adults with chronic medical conditions and older adults. Most children are infected at least once by age two. In the United 
States, it is estimated that over two million children younger than five receive medical attention and up to 80,000 are hospitalized due 
to RSV infection annually. RSV also causes a substantial burden of respiratory illness in older adults. RSV infection causes up to 
160,000 hospitalizations and up to 10,000 deaths per year in adults aged 65 years or older in the United States.
We are developing an RSV vaccine (mRNA-1345) for children, pregnant women and adults. mRNA-1345 encodes an engineered 
form of the RSV F protein stabilized in the prefusion conformation and is formulated in our proprietary LNP. In May 2024, we 
announced the FDA approved mRNA-1345, brand name mRESVIA, for the prevention of RSV-associated lower respiratory tract 
disease (RSV-LRTD) in adults 60 years or older. Subsequently, the Advisory Committee on Immunization Practices (ACIP) issued a 
recommendation for all unvaccinated people aged 75 years and older and unvaccinated people aged 60 to 74 who are at increased risk 
for RSV to receive the vaccine for the prevention of RSV-associated LRTD and acute respiratory disease. mRESVIA was approved in

the EU in August 2024 and in Canada in November 2024 for the same indication and ages. It has been approved in additional 
jurisdictions globally.
In September 2024, we announced that our Phase 3 (P303) study designed to test immunogenicity and safety in high-risk adults aged 
18 to 59 met all primary immunogenicity endpoints and was well-tolerated with no safety concerns identified. We filed a supplemental 
Biologics License Application (sBLA) for U.S. approval in December 2024 to extend the indicated age range of mRNA-1345 to high-
risk adults 18 to 59 years old using a priority review voucher, and have been assigned a PDUFA goal date of June 12, 2025. A Type II 
Variation in the EU and a Supplemental New Drug Submission in Canada were also filed in January 2025 for extension of the 
indication in those countries to high-risk adults 18 to 59 years old. 
We have additional Phase 3 studies that have generated data in adults to explore co-administration with licensed flu or COVID 
vaccines, revaccination with mRNA-1345, and expansion to adults aged 18 and older who are immunocompromised due to solid 
organ transplant. In pediatrics, mRNA-1345 has ongoing safety follow up in Phase 1 and Phase 2 studies, and we are conducting a 
Phase 2 study in maternal populations. In the third quarter of 2024, we announced the discontinuation of our program of RSV in 
infants (seronegative, <2 years).
Seasonal influenza vaccines (mRNA-1010, mRNA-1011, mRNA-1012, mRNA-1020 and mRNA-1030) 
The World Health Organization (WHO) estimates that seasonal influenza viruses cause three to five million cases of severe illness and 
290,000 to 650,000 deaths each year, resulting in a severe challenge to public health. Currently licensed seasonal influenza vaccines 
rarely exceed 60% overall effectiveness and can provide low effectiveness during years when the circulating viruses do not match the 
strains selected for the vaccine antigens. 
Our mRNA seasonal influenza vaccine program is taking an iterative approach to development. Our first-generation seasonal 
influenza vaccine candidate (mRNA-1010) encodes for the hemagglutinin (HA) proteins of the strains recommended by the WHO. We 
are intending to subsequently improve upon the first-generation candidate through inclusion of additional HA antigens that could 
provide expanded coverage of co-circulating strains, as well as broadening protection through the addition of another influenza 
protein, the neuraminidase (NA). We also aim to work with the WHO, regulators and public health authorities to enable strain 
selection closer to the influenza season to provide a better match to the circulating viruses.
The inclusion of additional HA antigens is being tested in our mRNA-1011/1012 programs, and the addition of NA antigens is being 
tested in our mRNA-1020/1030 programs. We aim to ultimately combine both approaches into a single next-generation vaccine. Phase 
1/2 studies for our mRNA-1011/1012 and mRNA-1020/1030 programs have been initiated and interim results have been presented at 
scientific meetings.
In February 2023, we announced interim results from the P301 study of mRNA-1010. The results indicated that mRNA-1010 achieved 
higher seroconversion rates for A/H3N2 and A/H1N1, as well as superiority on geometric mean titer ratios for A/H3N2 and non-
inferiority on geometric mean titer rations for A/H1N1. Non-inferiority was not met for either endpoints for the influenza B/Victoria- 
or B/Yamagata-lineage strains. mRNA-1010 showed an acceptable safety and tolerability profile. In April 2023, we announced the 
P302 study of mRNA-1010 did not accrue sufficient cases at the interim efficacy analysis to declare early success in the Phase 3 
Northern Hemisphere efficacy trial. In September 2023, we announced the P303 immunogenicity and safety study of mRNA-1010 met 
all 8 co-primary endpoints with an updated formulation that was able to generate an improved immune response to influenza B strains. 
mRNA-1010 also elicited higher titers than the licensed comparator against all strains in this study. In September 2024, we shared 
results in an older adult extension study of P303, where mRNA-1010 met all primary immunogenicity endpoints, including superiority 
for all strains, compared to a licensed enhanced flu vaccine and showed an acceptable reactogenicity profile. We also announced that 
we are no longer pursuing an accelerated approval pathway for mRNA-1010, and plan to start a confirmatory vaccine efficacy study, 
funded by project financing through Blackstone Life Sciences, a partnership we announced earlier in 2024. We have initiated the two-
season Phase 3 efficacy study (P304) for mRNA-1010.
Combination vaccines (mRNA-1083 and mRNA-1365)
We are developing combination vaccine candidates to simplify and facilitate protection against a range of respiratory diseases. 
mRNA-1083, our next-generation COVID and seasonal influenza combination vaccine, encodes the same antigens as our updated 
seasonal influenza vaccine (mRNA-1010) and our next-generation COVID vaccine (mRNA-1283). In June 2024, we announced that 
our Phase 3 clinical trial of mRNA-1083 met its primary endpoints, eliciting higher immune responses against influenza virus and 
SARS-CoV-2 than licensed flu and COVID vaccines in adults 50 years and older, including an enhanced influenza vaccine in adults 
65 years and older. We filed for FDA approval for mRNA-1083 in November 2024. We have also filed mRNA-1083 for approval in 
other geographies including the EU, Canada, Australia and the UK. Demonstration of vaccine efficacy in our ongoing Phase 3

mRNA-1010 flu study may be required to support approval of mRNA-1083 in some markets. In addition, we are preparing to start a 
Phase 2 study evaluating the safety, reactogenicity and immunogenicity of mRNA-1083 in adults aged 18 to 64.
Safety follow-up continues in our Phase 1 study for mRNA-1365 in children five to 23 months of age.
We are evaluating a new COVID, seasonal flu and RSV combination vaccine using our updated mRNA-1010 composition as well as 
our next-generation COVID vaccine (mRNA-1283), and are planning development in older adults. We also plan to evaluate an 
updated version of mRNA-1365, our RSV and hMPV combination vaccine in older adults.
We have discontinued development of mRNA-1230, our first-generation COVID, seasonal flu and RSV combination vaccine, and 
mRNA-1045, our seasonal flu and RSV combination vaccine.
Pandemic influenza vaccine (mRNA-1018) 
An influenza pandemic is a global outbreak of a new influenza A virus that is very different from current and recently circulating 
human seasonal influenza A viruses. Pandemic strains can arise by antigenic shift, which is the exchange of genetic segments between 
a (non-human) influenza virus with another influenza virus; this can occur through a simultaneous infection of an animal (e.g., swine) 
or humans with multiple influenza viruses. 
We are developing a pandemic influenza vaccine candidate that encodes for hemagglutinin (HA) glycoproteins with the support of 
Biomedical Advanced Research and Development Authority (BARDA). In 2023, we initiated a Phase 1/2 study to generate safety and 
immunogenicity data of our investigational pandemic influenza vaccine (mRNA-1018) in healthy adults 18 years of age and older. 
The study includes vaccine candidates against H5 and H7 avian influenza viruses.
In July 2024, we announced a project award of $176 million through the Rapid Response Partnership Vehicle (RRPV) to accelerate 
the development of mRNA-based pandemic influenza vaccines. In January 2025, the agreement was expanded through the RRPV, 
funded by BARDA. The agreement provides additional funding up to $590 million to support the late-stage development and licensure 
of mRNA-based pre-pandemic influenza vaccines. In addition, the funding will enable the expansion of clinical studies for up to five 
subtypes of pandemic influenza, enhancing our preparedness to address emerging public health threats. 
LATENT AND OTHER FRANCHISE
We have prioritized the development of vaccines against two latent and other viruses with unmet or underserved needs: our vaccine 
against cytomegalovirus (CMV) (mRNA-1647) and our trivalent norovirus vaccine (mRNA-1403). We have a total of 14 latent and 
other virus vaccines programs in our current portfolio, summarized below.
Vaccines against latent viruses
CMV vaccine (mRNA-1647)
CMV is a common human pathogen and member of the herpes virus family. Congenital CMV (cCMV) results when infected mothers 
transmit the virus to their unborn child and it is the leading infectious cause of birth defects in the United States. cCMV infection is 
well-established to occur at a rate of approximately 1 in 200 live births or 0.5%. As a result, the total number of infants in the U.S. 
born each year who are infected with cCMV fall within the range of 14,400-20,500. There is currently no available vaccine for CMV 
and a vaccine that leads to durable immunity in women of child-bearing age would address a critical unmet need in the prevention of 
congenital CMV infection. 
Our CMV vaccine candidate, mRNA-1647, combines six mRNAs in one vaccine. These six mRNAs encode proteins located on the 
surface of CMV: five mRNAs encode the subunits that form the membrane-bound pentamer complex and one mRNA encodes the 
full-length membrane-bound glycoprotein B (gB). Both pentamer and gB are essential for CMV to infect barrier epithelial surfaces 
and gain access to the body, which is the first step in CMV infection. mRNA-1647 is designed to produce an immune response against 
both pentamer and gB for the prevention of CMV infection, which could reduce the risk of birth defects and post-transplant infections.
We are conducting an ongoing pivotal Phase 3 study for mRNA-1647, known as CMVictory, to evaluate the safety and efficacy of 
mRNA-1647 against primary CMV infection in female participants 16 to 40 years of age. The study is fully enrolled and accruing 
cases. The Data Safety Monitoring Board (DSMB) met to review the initial study data in December 2024, and informed us that the 
criterion for early efficacy was not met. The DSMB recommended that the study continue as planned. We remain blinded and 
anticipate final efficacy data from the study in 2025.

We are also conducting a Phase 1/2 study of mRNA-1647 in participants 9 to 15 years of age. The study is enrolling and will evaluate 
the safety and immunogenicity of mRNA-1647 to inform the selection of a dose level for subsequent development in this age group. 
Additionally, in April 2023 we announced that a Phase 2 proof-of-concept study for mRNA-1647 in allogeneic hematopoietic cell 
transplant (HCT) patients had started enrollment. Enrollment is ongoing.
EBV vaccine (mRNA-1189 and mRNA-1195)
Epstein-Barr virus (EBV) is a member of the herpesvirus family that infects approximately 90% of people in the U.S. by adulthood, 
with primary infection typically occurring during childhood or late adolescence (approximately 50% and 89% seropositivity, 
respectively). EBV is the major cause of infectious mononucleosis, accounting for over 90% of the cases in the U.S. each year. 
Infectious mononucleosis can debilitate patients for weeks to months and, in some cases, can lead to hospitalization due to 
complications such as splenic rupture. EBV infection is also associated with the development and progression of certain 
lymphoproliferative disorders, cancers and autoimmune diseases. In particular, EBV infection and infectious mononucleosis are 
associated with increased risk of developing multiple sclerosis (MS), an autoimmune disease of the central nervous system. MS is the 
most common neurodegenerative disorder of the central nervous system, affecting approximately 2.8 million individuals worldwide of 
which approximately 1 million live in the U.S. MS leads to progressive disability, with profound socioeconomic impact on the 
patients, caregivers and the healthcare system.
We are developing two EBV vaccine candidates—a vaccine to prevent infectious mononucleosis (mRNA-1189) and a vaccine to 
prevent or treat the longer-term sequelae of EBV infection (mRNA-1195). We believe that an effective EBV vaccine must generate an 
immune response against antigens that are required for viral entry and reactivation in susceptible cell types. mRNA-1189 is designed 
to elicit an immune response to EBV envelope glycoproteins, which are required for infection of both epithelial and B cells. 
mRNA-1195 encodes for entry glycoproteins and latent antigens aimed at inducing an antibody and T cell response, and will be 
investigated in the context of post-transplant lymphoproliferative disorders and multiple sclerosis.
We are conducting Phase 1, randomized, observer-blind, placebo-controlled studies of mRNA-1189 and mRNA-1195. The primary 
purpose of these studies is to assess the safety, tolerability and immunogenicity of these vaccine candidates. In March 2024, we shared 
Phase 1 data for mRNA-1189, where the randomized, observer-blind, placebo-controlled study showed mRNA-1189 was 
immunogenic and generally well tolerated across all dose levels. We have since initiated a dose finding Phase 2 study for mRNA-1189 
that is currently in active enrollment. Our Phase 1 study for mRNA-1195 is ongoing, and we announced in March 2024 that the first 
part of the study was fully enrolled.
HSV vaccine (mRNA-1608)
Herpes simplex viruses (HSV), commonly known as herpes, are categorized into two types: HSV-1 primarily spreads by oral contact 
and is most commonly associated with cold sores, while HSV-2 spreads through sexual contact and is the main cause of recurrent 
genital herpes. Both viruses establish life-long latent infections within nearby sensory neurons from which they can reactivate and re-
infect the skin. There is a significant burden of disease from HSV genital infections. Diagnosed, symptomatic genital herpes causes a 
reduction in quality of life, which antivirals (current standard of care) only partially restore. In the United States, approximately 18.6 
million adults aged 18 to 49 years are living with HSV-2. Globally, an estimated 520 million persons have HSV-2 infection, 
representing 13% of the world’s population aged 15 to 49 years. We believe that an HSV vaccine could offer significant therapeutic 
benefit to patients, improve treatment compliance and quality of life. We aim to induce a strong antibody response with neutralizing 
and effector functionality combined with cell-mediated immunity.
We are conducting a Phase 1/2, randomized, observer-blind, controlled, dose-ranging study of mRNA-1608, our HSV vaccine 
candidate against recurrent HSV-2 disease, in health adults 18 to 55 years of age with recurrent HSV-2 genital herpes. The primary 
purpose of this study is to assess safety and immunogenicity data, and establish a proof-of-concept of clinical benefit. In March 2024, 
we announced that this study is fully enrolled with over 300 participants in the U.S.
VZV vaccine (mRNA-1468)
Herpes zoster, also known as shingles, is caused by reactivation of the varicella zoster virus (VZV) and occurs in approximately one in 
three adults in their lifetime, with incidence significantly increasing after 50 years of age. Protective immunity against VZV wanes as 
the immune system ages, allowing reactivation of the virus from latently infected neurons, causing painful and itchy lesions. Serious 
herpes zoster complications include postherpetic neuralgia (10-13% of herpes zoster cases), bacterial coinfections and cranial and 
peripheral palsies; 1-4% of individuals with herpes zoster cases are hospitalized for complications. Severity of disease and likelihood 
of complications, including postherpetic neuralgia (PHN) also increases with age. People with immunocompromising conditions, 
people using immunosuppressive therapies, people living with HIV, and hematopoietic stem cell (HSCT) and solid organ transplant

(SOT) recipients have an increased risk of developing herpes zoster. The current standard of care for prevention of shingles is 
Shingrix, an FDA-approved vaccine for use in adults 50 years and older, and other patients at increased risk for shingles due to 
immunodeficiency or immunosuppression caused by known disease or therapy. Shingrix was found to be more than 90% efficacious 
against herpes zoster in adults aged 50 to 70 over more than three years of follow-up in pivotal trials, with only a slight reduction in 
efficacy in adults over age 70.
We are conducting an ongoing Phase 1/2, randomized, observer-blind, active-controlled, dose-ranging study to evaluate the safety, 
reactogenicity and immunogenicity of mRNA-1468, compared head-to-head with Shingrix, in healthy adults, aged 50 years and older. 
The first participant was dosed in February 2023 and enrollment of 500 participants was completed in June 2023. Subsequently, we 
expanded the study to evaluate two additional dose levels, with enrollment now totaling over 650 participants. In March 2024, we 
presented initial data from a Phase 1/2 trial, which showed that mRNA-1468 elicited strong antigen-specific T cell responses at one 
month after the second dose and was generally well-tolerated. Results of the first interim analysis support the further clinical 
development of mRNA-1468 for the prevention of shingles.
HIV vaccine (mRNA-1644 and mRNA-1574)
HIV is the virus responsible for acquired immunodeficiency syndrome (AIDS), a lifelong, progressive illness with no effective cure. 
Approximately 38 million people worldwide are currently living with HIV, with 1.2 million in the U.S. Approximately 1.5 million 
new infections of HIV are acquired worldwide every year and approximately 680,000 people die annually due to complications from 
HIV/AIDS. The primary routes of transmission are sexual intercourse and IV drug use, putting young adults at the highest risk of 
infection. From 2000 to 2015, a total of $562.6 billion globally was spent on care, treatment and prevention of HIV, representing a 
significant economic burden.
We are developing two HIV vaccine candidates—mRNA-1644 and mRNA-1574—both of which are in Phase 1 clinical trials. In 
collaboration with the International AIDS Vaccine Initiative (IAVI), NIAID and the Gates Foundation, mRNA-1644 is testing a novel 
HIV vaccine strategy in humans as delivered by mRNA to elicit broadly neutralizing HIV-1 antibodies (bnAbs) through sequential 
vaccination of novel prime and boost antigens that induce specific B-cell responses. In collaboration with IAVI, Scripps, NIH and the 
HIV Vaccine Trials Network, mRNA-1574 is testing multiple native-like HIV trimer mRNAs in humans to improve our 
understanding of how to make stable and immunogenic native-HIV trimers. 
Vaccines against enteric viruses
Norovirus vaccines (mRNA-1403 and mRNA-1405) 
Norovirus is the leading cause of acute gastroenteritis (AGE), responsible for approximately 1 in 5 of all AGE cases worldwide and 
resulting in substantial health care burden. Annually, norovirus causes an estimated 677 million AGE cases and 213,000 deaths 
globally, including more than 70,000 deaths in children under the age of five. The global economic impact is estimated at $64.5 billion 
per year. The incidence of norovirus AGE is highest among young children, while disease severity is most pronounced in young 
children, older adults, and individuals with underlying medical conditions. In high-income settings such as the U.S., deaths are 
concentrated among older adults. Norovirus is highly infectious and difficult to control, often causing large and costly outbreaks in 
closed or semi-closed settings, including daycares, schools, cruise ships, long term care facilities and healthcare institutions. In the 
U.S., norovirus accounts for an estimated 20 million infections, 100,000 hospitalizations and 900 deaths annually, with an associated 
economic cost of approximately $10.6 billion. The burden of norovirus among older adults is expected to rise alongside societal aging 
and the rising demand for institutionalized care.  
Norovirus has broad genetic diversity; the virus is classified into 10 genogroups and 49 genotypes, 30 of which are known to infect 
humans. Vaccine development has been challenging to date for many reasons, including the lack of a robust cell culture system, no 
reliable immune markers of norovirus protection and the broad and shifting diversity of genotypes. A multivalent vaccine with broad 
genotype coverage is needed to maximize protection against the genotypes most frequently associated with AGE in young children 
and older adults.
We are currently developing pentavalent (mRNA-1405) and trivalent (mRNA-1403) vaccine candidates for norovirus. Both candidates 
were reviewed in a Phase 1 study to evaluate safety, reactogenicity and immunogenicity in healthy adult participants 18 to 49 years of 
age and 60 to 80 years of age. Approximately 660 participants were enrolled in the Phase 1 study, and dosing was completed in 
December 2023. In March 2024, we presented data demonstrating that a single dose of trivalent vaccine candidate mRNA-1403 was 
well-tolerated across all dose levels evaluated and elicited robust antibody responses against vaccine-matched norovirus genogroup I 
& II selected genotypes, including functional HBGA-blocking antibodies. In September 2024, we presented additional data that 
mRNA-1403 elicited robust histo-blood group antigen (HBGA) blocking antibody titers against a second strain in genotype II in older 
and younger adults.

In September 2024, we began dosing participants in a Phase 3 study of mRNA-1403. This Phase 3 trial is a randomized, observer-
blind, placebo-controlled trial evaluating the efficacy, safety and immunogenicity of mRNA-1403. The trial aims to enroll up to 
30,000 participants 18 years of age and older globally, across countries in the Northern Hemisphere (U.S., Canada, UK, Japan), and 
Panama and Australia. Up to 25,000 participants 60 years of age and older and up to 5,000 participants between 18 and 59 years of age 
will be enrolled to assess the ability of mRNA-1403 to protect against virus-matched moderate to severe norovirus AGE, with a focus 
on the older adult age group that is at greatest risk of severe outcomes including hospitalization and death. 
The two-season Phase 3 study of mRNA-1403 is fully enrolled in the Northern Hemisphere and we are preparing second season 
enrollment in the Southern Hemisphere. The trial is currently on FDA clinical hold following a single adverse event report of a case of 
Guillain-Barré syndrome, which is currently under investigation. We do not expect an impact on the study's efficacy readout timeline 
as enrollment in the Northern Hemisphere has already been completed. 
Bacterial vaccines
Lyme vaccines (mRNA-1975 and mRNA-1982)
Lyme disease is an illness caused by Borrelia bacteria, and is usually spread from the bite of a tick carrying the bacteria. Lyme disease 
affects approximately 120,000 people annually in the U.S. and Europe, with incidence increasing due to expanding tick territories 
driven by rising temperatures. The disease burden follows a bimodal age distribution, predominantly impacting children under 15 and 
older adults. Symptoms include rash, fever, headaches, fatigue, joint pain, swelling, stiffness, and headaches. While no vaccines are 
currently approved, prior Phase 3 trials of outer surface protein A (OspA) antigen-based vaccines achieved efficacy up to 92%, with 
protection linked to high levels of antigen-specific antibodies.
We are conducting a randomized, observer-blind, placebo-controlled, dose-ranging Phase 1/2 trial in healthy participants aged 18 to 
70. This trial evaluates the safety and immunogenicity of a heptavalent (mRNA-1975) and monovalent (mRNA-1982) approach in 
parallel. mRNA-1982 targets Borrelia burgdorferi, responsible for nearly all Lyme cases in the U.S., while mRNA-1975 targets the 
four major Borrelia species causing disease in the U.S. and Europe.
No safety concerns have been identified across the evaluated dose levels for three injections of mRNA-1975/1982. Furthermore, three 
injections of mRNA-1975/1982 elicit robust anti-OspA IgG antibody responses, with titers up to ~1,300 times above baseline for 
OspA serotype 1 of Borrelia burgdorferi.
Public health vaccines
Zika vaccine (mRNA-1893)
The Zika virus is a single stranded RNA virus of the Flaviviridae family. Sero-epidemiology data suggest that it is endemic to regions 
of Africa and Asia, where the Aedes mosquito vectors are found. Zika virus is predominantly spread by mosquitos from the Aedes 
genus, but it can also be transmitted congenitally, sexually and through blood donation. Zika infection is usually asymptomatic or mild 
in adults, leading to fever, rash and conjunctivitis. However, infection of women during pregnancy can result in devastating fetal 
outcomes, including miscarriages, stillbirths, premature births, and congenital anomalies collectively known as congenital Zika 
syndrome (microcephaly, limb contractures, high muscle tone, eye abnormalities and hearing loss) in newborns. Microcephaly is a 
birth defect characterized by an abnormally small head and brain, associated with lifelong neurodevelopmental delay, seizures, 
intellectual disability, balance problems and dwarfism/short stature, resulting in significant disability and requiring lifelong support. In 
2007, a Zika infection outbreak progressed across the Pacific islands. An outbreak observed in Brazil in 2015 soon spread across the 
Americas, which led the WHO to declare Zika a public health emergency of international concern in 2016. During the period, tens of 
thousands of cases of microcephaly and congenital Zika syndrome were reported in infants. Zika has also been associated with certain 
neurological sequelae, such as Guillain-Barré syndrome, reported in adults.
Our Zika vaccine candidate, mRNA-1893, encodes for the prME structural protein encapsulated in our proprietary LNP. In partnership 
with BARDA, we conducted Phase 1 and Phase 2 studies. Results of the Phase 1 study were previously published. 
In November 2024, we presented data from the randomized, observer-blind, placebo-controlled, dose confirmation Phase 2 trial to 
evaluate the safety, tolerability, and immunogenicity of three regimens of mRNA-1893: a single dose regimen (100 μg) or 2-dose 
regimens (30 μg or 100 μg given 28 days apart), in adults aged 18 to 65 living in flavivirus endemic and non-endemic areas. The trial 
enrolled 808 participants (approximately 200 participants per study arm) from the continental United States and Puerto Rico. The 
main portion of the trial followed participants for 6 months after the last dose, with an optional extension phase for follow up to 22 
months after last dose. Key findings from the main study showed that mRNA-1893 was generally safe and well tolerated, with no new 
safety concerns identified. Both 2-dose regimens (30 μg and 100 μg) elicited strong immune responses with no significant differences

in neutralizing antibody (nAb) geometric mean titers across baseline serostatus. Our data (up to end of main study) suggests that a 
single vaccination of mRNA-1893 in a flavivirus-experienced population may be sufficient to induce robust nAb responses against 
Zika virus; in contrast, a prime-boost strategy with 2-doses of the mRNA-1893 will likely be required in a flavivirus-naive population 
to obtain a similar level of immunogenicity/protection.
Approximately half of the main study participants opted in the extension phase, which was completed in 2024; data analysis of the 
extension phase will provide insight into the long-term safety and durability of immune response to mRNA-1893. At this time, we do 
not anticipate advancing the Zika program into further development in the absence of external funding.
Nipah vaccine (mRNA-1215) 
Nipah virus (NiV) is a zoonotic virus transmitted to humans from animals, contaminated food or through direct human-to-human 
transmission and causes a range of illnesses including fatal encephalitis. Severe respiratory and neurologic complications from NiV 
have no treatment other than intensive supportive care. The case fatality rate among those infected is estimated at 40-75%. NiV 
outbreaks cause significant economic burden to impacted regions due to loss of human life and interventions to prevent further spread, 
such as the slaughter of infected animals. NiV has been identified as the cause of isolated outbreaks in India, Bangladesh, Malaysia 
and Singapore since 2000 and is included on the WHO R&D Blueprint list of epidemic threats needing urgent research and 
development action. 
In collaboration with the NIH-Vaccine Research Center (VRC), we are conducting an ongoing Phase 1 clinical trial of mRNA-1215, 
our vaccine candidate against NiV, and testing will be focused on pandemic preparedness. This Phase 1 dose-escalation, open-label 
clinical trial is the first study of mRNA-1215 in healthy adults to evaluate the safety, tolerability and immunogenicity of a NiV mRNA 
vaccine candidate. The trial is sponsored and funded by the National Institute of Allergy and Infectious Diseases (NIAID).
Mpox vaccine (mRNA-1769)
Mpox is an infectious viral disease that affects humans and some other animals. It is caused by the monkeypox virus, a member of the 
Orthopoxvirus genus, which also includes Variola virus, the causative agent of smallpox. Although smallpox was eradicated in 1977, 
continued protection from smallpox is of great interest given the lethality of the infection and potential for use as an agent of 
bioterrorism. Other viruses associated with the Orthopoxvirus genus include cowpox, rabbitpox and camelpox.
There are two subtypes of the monkeypox virus—Clade I and Clade II, with Clade I endemic in Central Africa and Clade II in West 
Africa. Clade I is historically associated with more severe disease and increased mortality. Prior to 2022, mpox outbreaks were 
primarily sporadic, driven by zoonotic spillover in endemic regions. Transmission occurs mainly through close contact with lesions, 
bodily fluids and contaminated surfaces. Respiratory transmission via face-to-face interaction is also possible. The incubation period 
ranges from three to 17 days, followed by characteristic progressive rash and systemic symptoms, including fever, chills, 
lymphadenopathy, fatigue, muscle ache and headache. In 2022, a global outbreak of the Clade II mpox virus was declared a Public 
Health Emergency of International Concern by the WHO. The outbreak resulted in more than 124,000 confirmed cases across 128 
countries. The main mode of transmission during the 2022 global outbreak was sexual transmission. More recently, the Clade I 
monkeypox virus has also been linked to sexual transmission, during the ongoing outbreak in the Democratic Republic of the Congo 
(DRC), and with reports of travel-related cases of Clade I in non-endemic areas (North America, Europe, Asia), there is concern that it 
may lead to further global outbreaks. 
The current standard of care for mpox is JYNNEOS, which is approved by the FDA for the prevention of mpox and smallpox disease. 
Our mpox vaccine (mRNA-1769) expresses four antigens from the monkeypox virus and has been shown to provide protection against 
multiple routes of infection with monkeypox virus. In 2024, we published pre-clinical data showing that, in a stringent non-human 
primate model, mRNA-1769 resulted in lower lesions and reduced viral replication and induced enhanced neutralizing and functional 
antibodies compared to existing treatment. Additionally, neutralizing responses were found to cover a broad range of orthopox viruses, 
including ectromelia, rabbitpox, cowpox and camelpox viruses.
We are conducting a randomized, placebo-controlled, dose-ranging, observer-blind Phase 1/2 study to evaluate the safety, tolerability 
and immunogenicity of three dose levels of mRNA-1769 in healthy participants.
ONCOLOGY THERAPEUTICS FRANCHISE 
Within our oncology therapeutics franchise, we are developing INT (mRNA-4157) in collaboration with Merck. We and Merck are 
targeting a variety of tumor types, with Phase 3 trials ongoing in adjuvant melanoma, adjuvant non-small cell lung cancer (NSCLC) 
and adjuvant NSCLC post neoadjuvant treatment. The Phase 3 clinical trial for adjuvant melanoma completed enrollment in 2024. We

20

and Merck also have multiple Phase 2 and earlier trials ongoing. We have a total of 8 oncology programs in our current portfolio, 
summarized below.
Individualized Neoantigen Therapy (INT) (mRNA-4157) 
As tumors grow, they acquire mutations, some of which create new protein segments, or neoantigens, that can be presented on human 
leukocyte antigen (HLA) molecules in the tumor and recognized as non-self by T cells. While some of these neoantigens could be 
shared across tumors, the majority are completely unique to an individual patient’s tumor, in addition the presentation of those 
neoantigens is also dependent on a patient’s specific HLA type. 
Our INT, mRNA-4157, uses next generation sequencing and a machine-learning based algorithm to design an mRNA that encodes up 
to 34 neoantigens against each individual patient’s tumor mutations with specificity to their HLA type, and is predicted to elicit both 
class I (CD8) and class II (CD4) responses. The neoantigens are encoded in a single mRNA sequence and formulated in our 
proprietary LNPs designed for intramuscular injection. INT is manufactured using an automated workflow to enable a rapid 
turnaround time. 
We are developing mRNA-4157 in collaboration with Merck. In September 2022, Merck exercised its option for personalized cancer 
vaccines, including mRNA-4157, pursuant to the terms of our existing PCV Collaboration and License Agreement with Merck, which 
was amended and restated in 2018 (PCV Agreement, also referred to as the INT Agreement). Pursuant to the PCV Agreement, we and 
Merck will collaborate on further development and commercialization of mRNA-4157, and we will share costs and any profits and 
losses worldwide related to mRNA-4157 equally.
In December 2022, we announced that the randomized Phase 2 trial of mRNA-4157 had met its primary endpoint. The open-label 
Phase 2 study is investigating a 1 mg dose of mRNA-4157 in combination with Merck’s pembrolizumab (KEYTRUDA®), compared 
to pembrolizumab alone, for the adjuvant treatment of high-risk resected melanoma. The study showed that mRNA-4157 in 
combination with KEYTRUDA reduced the risk of recurrence or death by 44% (HR=0.56 [95% CI, 0.31-1.02]; one-sided p 
value=0.0266) compared with KEYTRUDA alone. The results were the first demonstration of efficacy for an investigational mRNA 
cancer treatment in a randomized clinical trial in melanoma. Adverse events observed were consistent with those previously reported 
in a Phase 1 clinical trial, which showed mRNA-4157 to be well-tolerated at all dose levels. 
In February 2023, mRNA-4157 received a Breakthrough Therapy Designation from the FDA, and in April 2023 mRNA-4157 received 
PRIME Scheme Designation from the EMA.   
In December 2023, we announced that at a planned median follow-up of approximately three years, mRNA-4157 in combination with 
KEYTRUDA showed sustained benefit, reducing the risk of recurrence or death by 49% (HR=0.510 [95% CI, 0.288-0.906]; one-sided 
nominal p=0.0095) and the risk of distant metastasis or death by 62% (HR=0.384 [95% CI, 0.172-0.858]; one-sided nominal p= 
0.0077) compared to KEYTRUDA alone in stage III/IV melanoma patients with high risk of recurrence following complete resection. 
This data was presented at the American Society of Clinical Oncology (ASCO) in June 2024, as well as translational biomarker data 
that suggests mRNA-4157 may benefit a broad patient population, irrespective of the status of PD-L1, TMB, ctDNA, and HLA 
heterozygosity. Three-year exploratory endpoint data also showed an encouraging trend in overall survival (OS) with the combination 
versus pembrolizumab monotherapy. 
We and Merck have rapidly expanded the INT program, initiating Phase 3 studies in the adjuvant setting in patients with high-risk 
melanoma and NSCLC, and the Phase 3 high-risk melanoma study completing enrollment in 2024. In 2024 we further expanded 
development into a Phase 3 allowing neoadjuvant treatment in patients with NSCLC; a Phase 2 adjuvant treatment in patients with 
renal cell carcinoma (RCC), or kidney cancer; a Phase 2 adjuvant treatment in patients with high-risk muscle-invasive bladder cancer 
(MIBC); and a Phase 2/3 neoadjuvant and adjuvant treatment in patients with cutaneous squamous cell carcinoma (cSCC). 
Checkpoint adaptive immune modulation therapy (mRNA-4359)
We are developing a checkpoint adaptive immune modulation therapy (AIM-T) (mRNA-4359) that encodes Indoleamine 2,3-
dioxygenase (IDO) and programmed death-ligand 1 (PD-L1) antigens. We designed mRNA-4359 with the goal of stimulating effector 
T cells that target and kill suppressive immune and tumor cells that express the target antigens. Our initial indications for mRNA-4359 
are advanced or metastatic cutaneous melanoma and NSCLC. 
We presented data from the Phase 1a study of mRNA-4359 at the European Society for Medical Oncology (ESMO) Congress in 2024, 
where in a population of patients with heavily pre-treated, advanced stage cancers, eight of 16 response-evaluable patients achieved a 
best overall response (BOR) of stable disease. Translational data showed antigen-specific T-cell responses were elicited by 
mRNA-4359 treatment; a proportion of activated, cytotoxic, and memory T cells were elevated and a proportion of regulatory T cells

21

and myeloid-derived suppressor cells (MDSCs) were diminished on-treatment. mRNA-4359 monotherapy was tolerable at all dose 
levels tested with most adverse events of low grade (grade 1–2) and manageable. Enrollment in the phase 1b portion of the study, 
which studied mRNA-4359 in combination with pembrolizumab in patients with advanced or metastatic checkpoint inhibitor 
refractory melanoma and NSCLC, is complete and results will be submitted to a scientific congress for presentation. Following results 
of the Phase 1b study, we began enrollment of the Phase 2 portion of the study in June 2024.
RARE DISEASE FRANCHISE
In our prioritized portfolio, we are pursuing rare disease therapies targeting two organic acidemias caused by deficient metabolic 
enzymes—propionic acidemia (PA) and methylmalonic acidemia (MMA). We have a total of seven rare disease programs in our 
current portfolio, summarized below.  
Propionic acidemia (PA) (mRNA-3927)
PA is a rare, inherited metabolic disorder with significant morbidity and mortality, affecting one in 100,000-150,000 individuals 
worldwide. PA is caused by pathogenic variants in the propionyl-coenzyme A carboxylase (PCC) α or β subunits (PCCA and PCCB 
genes, respectively), leading to PCC deficiency and subsequent accumulation of toxic metabolites. PA is characterized by recurrent 
life-threatening metabolic decompensation events (MDEs) and multisystemic complications. Multisystemic complications include 
neurological manifestations, cardiomyopathy, arrythmias, growth retardation, recurrent pancreatitis, bone marrow suppression and 
predisposition to infection. Long-term, insults by toxic metabolites cause complications in various organs, and cognitive outcome is 
negatively correlated with the number of MDEs. Currently, there is no approved therapy for PA that targets the underlying root cause 
of the disease. 
Our PA therapy candidate, mRNA-3927, is a novel, IV-administered, LNP-encapsulated dual mRNA therapy that encodes for PCCA 
and PCCB subunit proteins to restore functional PCC enzyme activity in the liver. By encoding for intracellular proteins, mRNA 
therapy has a potential role in preventing and treating acute metabolic decompensations.
The global Phase 1/2 clinical trial for mRNA-3927, the Paramount Study, is ongoing and we have fully enrolled all five dose 
optimization cohorts, as well as a dose confirmation cohort. The objective of the study is to evaluate the safety and pharmacology of 
mRNA-3927 in patients aged one year and older with PA. The primary endpoints are safety, pharmacokinetics and 
pharmacodynamics. Secondary endpoints include incidence and severity of adverse events and change in plasma biomarkers: 
methylcitric acid (2-MC) and 3-Hydroxypropionic acid (3-HP). We have received Rare Pediatric Disease Designation, Orphan Drug 
Designation and Fast Track Designation from the FDA and Orphan Designation from the European Commission for the PA program. 
Several critical milestones have been reached in the trial. mRNA-3927 has been generally well-tolerated to date with no events 
meeting protocol-defined dose-limiting toxicity criteria. Early results suggest potential decreases in annualized MDE frequency 
compared to pre-treatment, and the majority of patients have elected to continue on the open label extension study. Due to the 
objective and disease-defining nature of MDEs, regulators have provided initial support for MDE as a clinically meaningful, preferred 
primary clinical endpoint for development. We began generating registrational trial data in the Phase 1/2 study in 2024.
Methylmalonic acidemia (MMA) (mRNA-3705)
MMA is a rare, inherited metabolic disorder with significant morbidity and mortality caused by a deficiency in an enzyme called 
methylmalonyl-CoA mutase (MUT). There are an estimated 500-2,000 people with MMA MUT deficiency in the United States based 
on estimated birth prevalence (0.3-1.2:100,000 newborns) and mortality rates. Mortality is significant, with mortality rates of 50% for 
those with complete MUT deficiency (mut 0) (median age of death 2 years) and 40% for MMA patients with partial MUT deficiency 
(mut -) (median age of death 4.5 years) reported in a large European study. MMA mainly affects the pediatric population and usually 
presents in the first few days or weeks of life. The occurrence of acute metabolic decompensations is the hallmark of the disorder and 
decompensations are typically more frequent in the first few years of life. Each decompensation is life-threatening and often requires 
hospitalization and management at an intensive care unit. Survivors often suffer from numerous complications including chronic renal 
failure and neurologic complications such as movement disorders, developmental delays, and seizures. Consequently, the health-
related quality of life for MMA patients and their families is significantly impaired. There are currently no approved therapies that 
address the underlying defect for MMA. 
Our MMA therapy candidate, mRNA-3705, encodes for a missing or deficient hepatic enzyme. In an ongoing Phase 1/2 study, fifteen 
participants have been dosed. Thus far, all eligible participants have opted to participate in the Open-Label Extension study. To date, 
mRNA-3705 was generally well-tolerated to date with no discontinuations due to safety and no events meeting protocol-defined dose-
limiting toxicity criteria. Initial data is encouraging, with reductions in methylmalonic acid and other pathway biomarkers in 
participants, particularly at doses of at least 0.4 mg/kg Q2W. Early results suggest potential decreases in annualized rates of MMA-
related hospitalizations and MDEs compared to pre-treatment rates. We are working to identify an optimal dose and continue to

engage with the FDA, via the START Program, and other global regulators. We have agreed with the FDA on the pivotal study 
design, and we expect to start a registrational study in 2025.
 
Glycogen storage disease type 1a (GSD1a) (mRNA-3745)
GSD1a is a rare, inherited metabolic disorder caused by a deficiency in the catalytic activity of the intracellular protein glucose 6-
phostphatase (G6Pase). GSD1a patients suffer from severe fasting hypoglycemia, hepatomegaly, nephromegaly, lactic acidemia, 
hypertriglyceridemia, hyperuricemia, hypercholesterolemia, hepatic steatosis and growth retardation. In addition, hepatocellular 
adenomas occur in 70% to 80% of GSD1a patients by their third decade of life and carries risk of transformation into hepatocellular 
carcinomas. Proteinuria has been observed in over half of patients above 25 years of age. GSD1a occurs in approximately 1:100,000 
live births in the United States and the EU but is more common in Ashkenazi Jews where the incidence is reported to be 1:20,000 live 
births. There are an estimated 2,500 people in the United States and over 4,000 people in the EU with GSD1a. Although strict diet 
therapy, including frequent feeding with uncooked cornstarch, allows GSD1a patients to live into adulthood by preventing 
hypoglycemia, the underlying pathological processes remain uncorrected resulting in the development of many long-term 
complications including liver adenomas and hepatocellular carcinoma.
Our GSD1a therapy candidate, mRNA-3745, consists of an mRNA encoding for modified human G6Pase, and has been granted 
Orphan Drug Designation by the FDA and the European Medicines Agency (EMA). A Phase 1/2 study to evaluate the safety and 
pharmacology of mRNA-3745 in GSD1a patients 18 years of age and older is ongoing. We have observed encouraging signs of 
clinical benefit with mRNA-3745.
Ornithine transcarbamylase (OTC) deficiency (mRNA-3139)
Ornithine transcarbamylase (OTC) deficiency (OTCD) is an X-linked recessive disorder that is the most common urea cycle disorders 
(UCDs) in humans. OTCD prevents the breakdown and excretion of ammonia, allowing ammonia to accumulate, rising to toxic levels 
where it affects the central nervous system. With an incidence of approximately 1:57,000 live births, OTCD accounts for nearly half of 
all UCDs. OTCD causes high mortality and morbidity, particularly in males.
Our OTCD therapy candidate, mRNA-3139, is in preclinical development. mRNA-3139 is a chronic intravenous, mRNA, enzyme 
replacement therapy for OTCD, which may act as a bridge to liver transplant or a standalone therapeutic depending on efficacy. 
mRNA-3139 uses the same LNP as in our GSD1a program.
Phenylketonuria (PKU) (mRNA-3210)
PKU is a rare inherited metabolic disease, affecting approximately 40,000 patients in the United States, France, Germany, Italy, Spain 
and the UK. Mutations in the phenylalanine hydroxylase (PAH) gene encoding the PAH enzyme result in the inability to metabolize 
the essential amino acid Phe to Tyr in the liver. There is a high unmet medical need for patients with PKU with early and continuous 
treatment throughout life being fundamental to prevent the development of irreversible neuropsychiatric outcomes.
We determined that the product profile of our preclinical candidate, mRNA-3210, did not meet our criteria to move into the clinic. We 
are evaluating other preclinical assets for this indication.  
Crigler-Najjar Syndrome Type 1 (CN-1) (mRNA-3351)
CN-1 is a severe condition caused by the mutations in the UGT1A1 gene. CN-1 is characterized by high levels of a toxic substance 
called bilirubin in the blood (hyperbilirubinemia). It is caused by mutations in the UGT1A1 gene, which results in an inability to break 
down bilirubin, a substance made by the liver. Without the UGT1A1 enzyme, bilirubin can build up in the body and lead to jaundice 
and damage to the brain, muscles and nerves. The symptoms become apparent shortly after birth and can be life-threatening. It is 
estimated that there are only approximately 70-100 known cases of CN-1 in the world. Affected individuals rely on current standard of 
care, phototherapy treatments of up to 12 hours a day, throughout life. The only definitive treatment is liver transplant, which is 
associated with its own set of side effects and risk of death.
Our CN-1 therapy candidate, mRNA-3351, consists of an mRNA encoding human UGT1A1 encapsulated in our proprietary LNPs. It 
is designed to restore the missing or dysfunctional protein that causes CN-1. We have licensed mRNA-3351 to Institute for Life 
Changing Medicines (ILCM) with no upfront fees and without any downstream payments. The goal of the collaboration is to make an 
mRNA therapy for the treatment of CN-1 available at no cost to patients. We are collaborating with the ILCM in developing a 
preclinical package for Investigational New Drug application and Clinical Trial Application filings. ILCM will be responsible for the 
clinical development of mRNA-3351.

Cystic Fibrosis (CF) (mRNA-3692/VX-522)
CF is a rare genetic disease, which is progressive from birth and leads to multi-organ damage and early death due to lung dysfunction. 
It is caused by the mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, which results in the loss of 
CFTR chloride ion channel function. This decreased function of CFTR at the cell surface leads to thick, sticky mucus in multiple 
organ systems but most pathologically the lungs. There are approximately 92,000 patients living with cystic fibrosis in the United 
States, Europe, Australia and Canada, with over 5,000 of these patients not being able to benefit from the approved CFTR modulators. 
We are collaborating with Vertex on our CF candidate, mRNA-3692/VX-522, which is designed to treat the underlying cause of CF 
by enabling cells in the lungs to produce functional CFTR protein for the treatment of the 10% of patients who do not produce any 
modulator-responsive CFTR protein. This would be our first demonstration of a nebulized mRNA therapy. The FDA has granted 
VX-522 Fast Track designation.
The multiple ascending dose (MAD) portion of the Phase 1/2 study of VX-522 is underway, with data expected in the first half of 
2025.
PROGRAMS DISCONTINUED IN 2024
As a result of portfolio prioritization and emerging clinical data, we elected to discontinue a number of programs in 2024 as we focus 
our research and development efforts. We do not have current plans for future development of the following programs:
•
mRNA-0184: Relaxin (program wrapping up Phase 1)
•
mRNA-1045: Seasonal flu and RSV combination vaccine
•
mRNA-1230: First-generation COVID, seasonal flu and RSV combination vaccine 
•
mRNA-1287: Endemic HCoV (the preclinical program will not advance to Phase 1)
•
mRNA-1345 and mRNA-1365: We have discontinued RSV development in children < 2 years (seronegative)
•
mRNA-6981: PD-L1 (the preclinical program will not advance to Phase 1)
•
mRNA-5671: KRAS antigen-specific therapy (no further development plans)
•
mRNA-2752: OX40L/IL-23/IL-36γ (Triplet) (we have deprioritized further development based on emerging clinical data)
MANUFACTURING 
Manufacturing plays a critical role in our value chain and our ability to develop our medicines. Our manufacturing capabilities support 
every stage of the development of our products, from discovery to commercialization. During the research stage of product 
development, manufacturing provides mRNA drug substance and drug product for platform research and therapeutic area drug 
discovery. During early development of our product candidates, we manufacture mRNA and drug product for IND-enabling GLP 
toxicology studies and initial human clinical studies. For late clinical development, we produce mRNA and drug product for Phase 3 
trials. At the commercial stage, we manufacture drug substance and drug product in collaboration with our contract manufacturing 
organizations (CMOs), both in the United States and internationally.
Overview of our manufacturing operating model 
Our manufacturing activities generally focus on: 
•
Commercial Production: Our manufacturing capabilities include state-of-the-art technologies for mRNA and drug substance 
manufacturing, as well as quality control testing to attain a robust and consistent supply that matches target product profiles. 
Our manufacturing technology is built to scale-up and support production of products for commercial approval. Our platform 
allows for efficient manufacturing at scale. 
•
Research and Development Support: The product supply enables platform research and drug discovery in our therapeutic 
and vaccine areas, in addition to activities related to clinical studies of our product candidates. 
We have built a dedicated in-house, multi-building manufacturing campus in Norwood, Massachusetts, the Moderna Technology 
Center (MTC). In December 2024, we purchased the MTC campus, including the underlying land and buildings, providing greater 
operational flexibility and long-term stability in supporting our manufacturing and development capabilities. The MTC provides 
supply for our preclinical research, IND-enabling GLP toxicology study supplies, our Phase 1 and Phase 2 pipeline activities, later-
stage clinical development activities (e.g., Phase 3 CMV vaccine clinical trials), as well as drug substance commercial production for 
vaccines. Our vaccine drug substance production for the U.S. market is completed at our MTC campus. The MTC has been designed 
to allow us to continue to optimize our mRNA products as we explore new pharmaceutical delivery forms in our manufacturing

network such as prefilled syringes. The MTC campus has been designed with a high level of automation and state-of-the-art digital 
integration to handle manufacturing execution, product testing and release, and regulatory filings.  
In the second quarter of 2023, we acquired a newly constructed, 140,000 square feet biomanufacturing facility in Marlborough, 
Massachusetts. The facility is undergoing enhancements, including the addition of 60,000 square feet to the existing structure. We 
expect the facility to be operational in 2025. This new site is strategically intended to support our INT program.
Internationally, we expect to bring state-of-the-art mRNA manufacturing facilities online in Australia, Canada and the United 
Kingdom in 2025. The government in each of these countries has entered into a multi-year commitment to purchase mRNA products 
from us once the covered respiratory vaccine products are approved and the local facilities are licensed for production. We expect that 
these local manufacturing facilities will provide direct access to rapid pandemic response capabilities and our respiratory virus vaccine 
candidates. We may seek to enter into future agreements with other governments to provide similar manufacturing capabilities in other 
geographies. 
In addition to our internal manufacturing facilities, we also maintain relationships with CMOs in the United States and abroad, 
providing critical raw material production and fill-finish capacity for our vaccines.   
Manufacturing technology development 
To support our broad pipeline of products, which spans multiple therapeutic areas and routes of administration, our platform research 
and technical development teams closely collaborate to facilitate rapid and seamless clinical translation of scientific breakthroughs. 
This enables us to develop potential medicines to serve a broad patient population. 
Technical development encompasses the design and optimization of robust and consistent manufacturing processes, product 
characterization, fit-for-purpose formulations and product presentations. For instance, our novel hardware platforms’ automation and 
robotics, coupled with the flexibility of our in-house digital development systems, allows for thousands of experiments and process 
parameters across our projects, thus supporting our drug product pharmaceutical readiness. Moreover, our recent technical 
manufacturing advances have enabled internalization of new key capabilities, including DNA plasmids and small molecules. 
In parallel, we continue to refine existing processes, resulting in increased manufacturing capabilities. These improvements allow us 
better control over our supply chain, resulting in larger production yields and longer shelf life of our products. Furthermore, 
formulation development advancements have added new drug product images, including lyophilization, giving us a path from frozen 
to refrigerated storage conditions. 
Our substantial investments in recent years in technical development has enabled the breadth and depth of our pipeline, and laid the 
foundation to help meet the needs and requirements associated with late-stage development and the commercialization of our products. 
Supply of mRNA for All Stages of Product Development and Commercialization 
Supply for Research 
High-throughput automation and custom engineered equipment allow us to produce and deliver high quality mRNA and formulated 
constructs in a short period of time: our proprietary platform is capable of producing up to 1,000 lots of mRNA sequences and 
formulations per month with a turnaround time of a few weeks from sequence to final product. The typical scale of mRNA 
manufactured by this team is 1-1,000 mg. This has been possible, in part, due to the ability of researchers in the Moderna ecosystem to 
order constructs through an integrated digital portal that tracks materials end-to-end in less than 45 days. In addition, multiple 
integrated algorithms that leverage artificial intelligence and machine learning optimize manufacturability, reduce failures and increase 
quality of mRNA sequences. 
Supply for Clinical Development 
We have established manufacturing capabilities that support the early development stage of product development in three key areas: 
GLP Tox, Clinical Studies and INTs. We supply formulated product to conduct IND-enabling GLP toxicology studies. In addition, 
human clinical studies rely on supply to meet required cGMP standards. This is achieved via internal manufacturing at the MTC 
campus. Our MTC campus is also suited to enable rapid technology development and scale-up for future needs.  
Our manufacturing also produces cGMP INTs. Due to the specialized nature of personalized medicine (i.e., where a batch is 
specifically designed and manufactured for a single patient), the manufacturing process for INTs has unique requirements. We 
digitally integrate patient-specific data from sequencing tumor samples to automatically design INTs for patients. We have developed 
proprietary bioinformatics designed algorithms linked to an automated manufacturing process for rapid production of formulated

mRNA, with a typical turnaround time of a few weeks. We have operationalized INT manufacturing at the MTC campus to meet our 
Phase 1 and 2 pipeline supply needs by using single-use systems with fast “needle-to-needle” turnaround times. Unlike traditional 
process development, each INT batch is manufactured for a single patient and thus scaled-out (in parallel) with extensive use of 
automation and robotics to account for the larger number of patients involved in later phases of development and commercialization. 
We have shown consistent quality in our production of many patient batches, each with unique mRNA sequences. In the second 
quarter of 2023, we acquired a new manufacturing facility in Marlborough, Massachusetts, which we expect to support our INT 
program. Upon completion, the facility will have state-of-the-art mRNA manufacturing areas, including a full manufacturing clean 
room, quality control laboratories, and a just-in-time satellite warehouse.
Our manufacturing capabilities have allowed us to build our broad pipeline of development programs, including the output required to 
supply related toxicological and human clinical studies. While the technology that underpins these programs is the same, each program 
typically requires customization based on target product profiles. These custom features range from varying molecular architecture to 
different routes of administration, often requiring multivalent products. All programs, except for INT, require that we progressively 
scale up supply to meet clinical demand requirements across development phases, in addition to the necessary preparation for 
regulatory approval and commercial production, which demand larger batch sizes. In contrast, the INT program seeks to develop a 
cancer therapeutic that is designed and manufactured for a specific patient, thus increasing the number of unique batches. As we scale 
manufacturing output for each program, we plan to continuously improve yield, purity and the pharmaceutical properties of our 
product candidates. 
Supply for Late-Stage Development and Commercialization 
Our development pipeline continues to advance to later-stage development and towards commercialization. Our platform approach 
allows us to continue to evolve our manufacturing suites and other capabilities at our manufacturing facilities. mRNA manufacturing 
is flexible and one plant can manufacture multiple vaccines and therapeutics. Our manufacturing facilities also permit us to 
manufacture products in parallel. For instance, we can produce drug substance and drug product for our Phase 3 CMV clinical trial 
while manufacturing COVID-19 drug substance in the same facilities. 
Quality Unit 
Quality is core to the way we operate. We seek to ensure quality at Moderna through a combination of a robust Quality Management 
System (QMS), our quality culture and our people. In accordance with applicable regulations, we have established, documented and 
implemented a QMS to assure continued compliance with the requirements therein. The QMS facilitates cGMP compliance by 
implementing practices that identify the various required processes, their application throughout the organization and the sequence of 
interaction of these processes. 
The primary mode of documenting these key practices is through policies, standard operating procedures (SOPs), forms and other 
quality records, which include an overarching Quality Policy and Quality Manual. We have implemented tools and metrics to monitor, 
measure, and analyze these practices to support cGMP operations, achieve planned results, and support continuous improvement. We 
monitor these quality metrics through formal governance processes, including Quality Management Review (QMR), to enable 
continuous improvement. We have also established an independent Quality Unit that fulfills quality assurance and quality control 
responsibilities. 
Environment, Health, and Safety 
We have established a global Environment, Health, and Safety (EHS) organization to foster a safe and healthy work environment with 
a focus on sustainability and compliance. Our approach integrates environmentally responsible practices with health and safety 
measures focused on risk reduction to promote long-term workplace well-being and environmental stewardship. We achieve this 
through a combination of training, procedures, digital data collection and reporting tools, and corporate programs that drive towards 
continuous improvement. 
Supply Chain Unit 
We have established a global supply chain to enable supply of the raw materials and components used to produce our products, 
consistent with clinical and preclinical demands. We have worked with our external vendors to characterize critical raw materials and 
to understand their impact on the quality of drug substance and formulated drug product. We also assess the quality system and 
performance of our external vendors and work with them to comply with regulatory requirements. In addition, we have established an 
infrastructure to enable direct-to-customer shipments for our commercial products. We leverage third-party wholesalers and integrate 
with artificial intelligence-driven data analytics to ensure successful ordering and delivery.

Engineering
Our global engineering organization is structured to deliver exceptional facilities and services. We partner closely with external and 
internal service providers to incorporate robotics, automation and predictive analysis for equipment operation. Engineering plays a 
critical role in the design, build, operation and maintenance of our facilities.
DIGITAL AND AI STRATEGY
Since our founding, we have been a digital-first company, seeking to use the power of digital information to maximize our impact on 
patients. mRNA is an information molecule, and our company was built on the premise that the natural flow of information in life can 
be used to develop medicines. Leveraging over a decade of experience developing mRNA medicines, we have built a large library of 
data that, combined with our platform approach and cloud-native infrastructure, positions us well to scale a digital operating model 
using artificial intelligence (AI).
Led by our Chief People and Digital Technology Officer, our digital organization partners across all Moderna functions to perpetuate 
and grow Moderna's AI-native culture. To that end, in 2021, we launched our AI Academy, which offers cross-organization training to 
all of our employees on how they can use AI to transform the way we work. Through the AI Academy, our employees learn how to 
leverage AI in their specific job functions to augment their capacity and capabilities, and to maximize our impact on patients. 
AI helps optimize each aspect of our value chain, from drug design to commercial manufacturing and beyond. At the research stage, 
our digital and AI infrastructure allows our scientists to design novel mRNA constructs, use AI algorithms to optimize them and order 
them from our high throughput preclinical scale production line. Our capabilities allow us to design mRNA, protein and LNP 
components with desired properties, such as reduced toxicity or increased stability. At the product development stage, AI helps to 
improve the efficiency of our clinical trial operations by, for example, forecasting participant enrollment and automating clinical trial 
data processing. 
Our manufacturing processes likewise utilize the power of AI. For example, we leverage a series of fully autonomous, integrated AI 
algorithms in connection with manufacturing mRNA-4157, our INT candidate. Our machine-learning based algorithms design the 
specific therapy for each individual patient and optimize the timely manufacture and delivery of INT to each patient. 
At the commercial stage, our digital and commercial organizations partner to drive performance and prepare for product launches. 
Digital and AI are key components of our commercialization strategy and are vital to our ability to increase our speed to market, 
enhance our commercial capabilities and continuously improve the quality of our products. We believe that our ability to move with 
both scale and speed positions us well to pursue our goals related to future product launches.
In early 2023, we began a collaboration with OpenAI to co-innovate with a shared vision of AI’s transformative potential in the future 
of business and healthcare. In 2024, our AI culture led to the deployment across the company of ChatGPT Enterprise and its enhanced 
capabilities such as Advanced Analytics, Image Generation and GPTs. These GPTs are now embedded across our business functions, 
including legal, research, manufacturing and commercial, helping to drive productivity. For example, our Dose ID GPT uses ChatGPT 
Enterprise’s Advanced Data Analytics feature to further evaluate the optimal vaccine dose selected by the clinical study team. By 
applying standard dose selection criteria and principles, Dose ID provides a rationale, references its sources, and generates informative 
charts illustrating the key findings. This allows for a detailed review, led by humans and augmented with AI input, while prioritizing 
safety and optimizing the vaccine dose profile prior to further development in late-stage clinical trials.  
We believe that the integrated AI ecosystem we are building at Moderna will accelerate our mission to deliver the greatest possible 
impact to people through mRNA medicines. 
COMMERCIAL
We continue to build our differentiated commercial model, with active commercial subsidiaries in key markets across North America, 
Europe and the Asia-Pacific region. Our commercial footprint provides us with local commercial teams in major markets where 
respiratory vaccines have high utilization rates and sales. To support the build out of our commercial activities in markets worldwide, 
we have hired talent with extensive pharmaceutical company experience. Our commercial teams also work with third-party 
distributors and other partners in countries where we do not have a direct presence. Our commercial activities are dependent on 
regulatory approvals and on agreements that we have made or may make in the future with strategic collaborators. 
We currently have two commercial products—Spikevax (our COVID vaccine) and mRESVIA (our RSV vaccine), which is approved 
for adults aged 60 and older. The commercial markets for these vaccines are seasonal and characterized, particularly in the U.S. (our 
largest market), by a fragmented customer base, unpredictability in orders and seasonality of deliveries. The private vaccine market is 
also characterized by market practices regarding rebates, discounts and returns. The respiratory vaccine market, and markets for

COVID and RSV vaccines in particular, depends on many factors such as medical need, viral evolution, public health authority 
recommendations and consumer motivation to vaccinate. The market volume for COVID vaccines has been relatively stable for two 
years, and public health recommendations for vaccinations are normalizing. We are encouraged to see the emergence of a sizable and 
durable long-term COVID vaccine market. 
Beyond Spikevax and mRESVIA, we continue to advance a broad seasonal respiratory vaccine franchise, consisting of single-agent, 
next-generation and combination vaccines against respiratory viruses that have the highest medical burden. In 2024, we filed for 
regulatory approval of our next-generation COVID vaccine, our RSV vaccine for high-risk adults aged 18 to 59, and our flu+COVID 
combination vaccine for adults 50 years and older. We anticipate potential product launches for each of these products as early as 
2025, with additional potential approvals of our seasonal flu vaccine and flu+COVID combination vaccine for adults aged 18 to 49 
over the next several years.
In addition to our respiratory vaccine franchise, we are also investing in building out our commercial capabilities for other franchises, 
including latent and other virus vaccines, rare disease therapeutics and oncology therapeutics. We expect to launch products in each of 
these franchises over the next several years.
Additionally, we expect to bring state-of-the-art mRNA manufacturing facilities online in Australia, Canada and the United Kingdom 
in 2025. The government in each of these countries has entered into a multi-year commitment to purchase mRNA products from us 
once the covered respiratory vaccine products are approved and the local facilities are licensed for production. See “—Manufacturing” 
above for further detail.
THIRD-PARTY STRATEGIC ALLIANCES
Strategic alliances
We are party to strategic alliances with a diverse group of collaborators, including pharmaceutical and biotechnology companies, 
government agencies, academic laboratories, foundations and research institutes with therapeutic area expertise and resources. 
Through our collaborations, we seek to advance our discovery and development programs, while leveraging our platform and our 
research and early development capabilities. From time to time, we also partner with and invest in companies developing other types 
of therapeutics, such as gene editing and cell-therapy, where we believe we can leverage our core mRNA and LNP capabilities to 
expand the reach of our technology.
Through certain of our strategic alliances, we share the rewards and risks of developing a new mRNA modality or program, where we 
may have early research data and desire a strategic collaborator to join us in advancing early development candidates within such 
modality into the clinic. Representative relationships and associated programs include those with Merck, for our INT programs 
(mRNA-4157), and Vertex, for our CF program (mRNA-3692).
To maintain the integrity of our platform, our strategic collaboration agreements generally grant either us the rights to develop and 
commercialize potential mRNA medicines we design and manufacture, or grant our collaborators those rights. These agreements do 
not allow collaborators to use our platform to generate new mRNA technologies, and we generally retain ownership of intellectual 
property related to our platform arising from research conducted under the alliance. We may continue to identify potential strategic 
collaborators who can contribute meaningful technology and insights to our programs and allow us to expand our impact more rapidly 
to broader patient populations. 
Below are brief descriptions of certain of our ongoing collaborations.
Merck—Strategic Alliance for Individualized Neoantigen Therapies
In June 2016, we entered into a Collaboration and License Agreement with Merck for the development and commercialization of 
personalized mRNA cancer vaccines (also known as INTs), which was subsequently amended and restated in 2018 (the INT 
Agreement), to develop and commercialize INTs for individual patients using our mRNA vaccine and formulation technology. Under 
the strategic alliance, we identify genetic mutations present in a particular patient’s tumor cells, synthesize mRNA for these mutations, 
encapsulate the mRNA in one of our proprietary LNPs and administer to each patient a unique INT designed to specifically activate 
the patient’s immune system against her or his own cancer cells.
Pursuant to the INT Agreement, we received an upfront payment of $200 million from Merck and we were responsible for designing 
and researching INTs, providing manufacturing capacity and manufacturing INTs and conducting Phase 1 and Phase 2 clinical trials 
for INTs, alone and in combination with KEYTRUDA (pembrolizumab), Merck’s anti-PD-1 therapy, all in accordance with an agreed 
upon development plan and budget.

In September 2022, Merck exercised its option for INTs, including mRNA-4157, pursuant to the terms of the INT Agreement and in 
October 2022 paid us an option exercise fee of $250 million. Pursuant to the INT Agreement, we and Merck have agreed to 
collaborate on further development and potential commercialization of INTs, with costs and any profits or losses generally shared 
equally on a worldwide basis, subject to certain exceptions as outlined in the agreement. 
Vertex—2016 Strategic Alliance in Cystic Fibrosis
In July 2016, we entered into a Strategic Collaboration and License Agreement (Vertex Agreement) with Vertex Pharmaceuticals 
Incorporated, and Vertex Pharmaceuticals (Europe) Limited (together, Vertex). The Vertex Agreement is aimed at the discovery and 
development of potential mRNA medicines for the treatment of CF by enabling cells in the lungs of people with CF to produce 
functional CFTR proteins.
Other Collaborations
We have entered into additional collaborations where we have agreed to provide funding in areas where we believe we can leverage 
our mRNA technology. These collaborations include those with:
•
Carisma Therapeutics, to discover, develop and commercialize in vivo engineered chimeric antigen receptor monocyte 
(CAR-M) therapeutics for the treatment of cancer, including solid tumors, and autoimmune diseases.
•
CytomX Therapeutics, to create investigational mRNA-based conditionally activated therapies utilizing our mRNA 
technologies and CytomX’s Probody platform.
•
Generation Bio Co., to combine our biological and technical expertise with core technologies of Generation Bio's non-viral 
genetic platform. 
•
Immatics N.V., to pioneer novel and transformative therapies for cancer patients with high unmet medical need.
•
Life Edit Therapeutics, to discover and develop in vivo mRNA gene editing therapies.
We have made equity investments in Carisma and Generation Bio pursuant to those collaborations.
Strategic alliances with government organizations and foundations
Defense Advanced Research Projects Agency (DARPA)
In September 2020, we entered into an agreement with DARPA to fund development of a mobile manufacturing prototype leveraging 
our existing manufacturing technology that is capable of rapidly producing vaccines and therapeutics.
Biomedical Advanced Research and Development Authority (BARDA)
COVID vaccine program
In April 2020, we entered into an agreement with BARDA for an award of up to $483 million to accelerate development of 
mRNA-1273, our original COVID vaccine. The agreement has been subsequently amended to provide for additional commitments to 
support various late-stage clinical development efforts of mRNA-1273, including a 30,000 participant Phase 3 study, pediatric clinical 
trials, adolescent clinical trials and pharmacovigilance studies. The maximum award from BARDA, inclusive of all amendments, was 
approximately $1.8 billion. All contract options have been exercised. As of December 31, 2024, the remaining available funding, net 
of revenue earned was $63 million.
Pandemic influenza program
In June 2024, we were awarded up to $176 million through the Rapid Response Partnership Vehicle (RRPV) Consortium, funded by 
BARDA, to accelerate the development of mRNA-based pandemic influenza vaccines. The project award will support the late-stage 
development of an mRNA-based vaccine to enable the licensure of a pre-pandemic vaccine against the H5 influenza virus. This 
subtype of the influenza virus causes a highly infectious and severe disease in birds known as avian influenza and poses a risk of 
spillover into the human population. The agreement also includes additional options to prepare and accelerate a response to future 
public health threats.
In January 2025, we were awarded up to $590 million through the RRPV, funded by BARDA. This funding builds on the $176 million 
award received in June 2024 and will provide additional support for late-stage development and licensure of pre-pandemic mRNA-
based influenza vaccines. The agreement will also support the expansion of clinical studies for up to five additional subtypes of 
pandemic influenza.

Institute for Life Changing Medicines (ILCM)
In September 2021, we entered into a collaboration agreement with the ILCM to develop a new mRNA therapeutic (mRNA-3351) for 
type 1 Crigler-Najjar syndrome (CN-1). Under the terms of the agreement, we agreed to license mRNA-3351 to ILCM with no upfront 
fees, and without any downstream payments. ILCM will be responsible for the clinical development of mRNA-3351.
The Gates Foundation
In January 2016, we entered a global health project framework agreement with the Bill & Melinda Gates Foundation (n/k/a the Gates 
Foundation) to advance mRNA development projects for various infectious diseases. The Gates Foundation has committed up to $20 
million in grant funding to support our initial project related to the evaluation of antibody combinations in a preclinical setting as well 
as the conduct of a first-in-human Phase 1 clinical trial of a potential mRNA medicine to help prevent HIV infections. Follow-on 
projects, which could bring total potential funding under the framework agreement up to $100 million (including the HIV antibody 
project) to support the development of additional mRNA projects for various infectious diseases, can be proposed and approved until 
the sixth anniversary of the framework agreement, subject to the terms of the framework agreement, including our obligation to grant 
to the Gates Foundation certain non-exclusive licenses.
INTELLECTUAL PROPERTY
We rely on a combination of intellectual property laws, including patent, trademark, copyright and trade secret, as well as 
confidentiality and license agreements, to protect our intellectual property and proprietary rights. 
Protecting our platform, modality and program investments: Building an expansive, multi-layered IP estate
We have built a substantial IP estate that includes numerous patents and patent applications related to the development and 
commercialization of mRNA vaccine and therapeutic development candidates, including related platform technologies. Our platform 
IP protects advances in mRNA design and engineering, proprietary LNP components, delivery systems, processes for the manufacture 
and purification of drug substances and products and analytical methods. A significant portion of our platform IP estate further 
provides multi-layered protection for our modalities and programs.
With respect to our IP estate, our solely-owned patent portfolio consists of more than 260 issued or allowed U.S. patents or patent 
applications and more than 140 granted or allowed patents in jurisdictions outside of the U.S. (including granted European patents that 
have been validated in numerous European countries) covering certain of our proprietary platform technology, inventions and 
improvements, and covering key aspects of our clinical and most advanced development candidates. We have 700 additional pending 
patent applications that, in many cases, are counterparts to the foregoing U.S. and foreign patents.
Most of the patents and applications (if issued) in our portfolio will not expire until 2033 at the earliest. Any patent that may issue 
from our most recently filed patent applications is projected to expire between 2043 and 2044, at the earliest. We file additional U.S. 
and foreign patent applications in key markets as necessary to protect our evolving intellectual property positions.
We also rely on trademarks, copyright, trade secrets and know-how relating to our proprietary technology and programs, continuing 
innovation, and in-licensing opportunities to develop, strengthen and maintain our proprietary position in the field of mRNA 
therapeutic and vaccine technologies. We take additional steps, such as entering into confidentiality and license agreements, to protect 
our intellectually property and proprietary rights. We additionally plan to rely on data exclusivity, market exclusivity and patent term 
extensions when and where available, and plan to seek and rely on regulatory protection afforded through orphan drug designations. 
We also possess substantial proprietary know-how associated with related manufacturing processes and expertise.
IP protecting our platform
We have a broad IP estate covering key aspects of our platform. This estate provides multiple layers of protection covering the making 
and use of the mRNA drug substance and delivery technologies.
With respect to our platform, we have a portfolio that includes U.S. and foreign patents or patent applications covering platform 
innovations that are related to the design, manufacturing and formulating of mRNA medicines. For example, these patents and patent 
applications include claims directed to:
•
mRNA chemistry imparting improved properties for vaccine and therapeutic uses;
•
methods for mRNA sequence optimization to enhance the levels and fidelity of proteins expressed from our mRNA medicines;
•
methods for identifying epitopes having superior suitability in cancer vaccine contexts;
•
engineering elements tailored to enhance stability and the in vivo performance of mRNA medicines;

•
LNP delivery systems, including novel lipid components designed for optimal delivery and expression of both therapeutic and 
vaccine nucleic acids, in particular, prophylactic infectious disease and cancer vaccine nucleic acids, intratumoral immuno-
oncology therapeutics, local regenerative therapeutics, systemic therapeutics, and inhaled pulmonary therapeutics; and
•
innovative processes for the manufacture and analysis of mRNA drug substance and formulated drug product.
IP protection
Our IP estate provides protection for the multiple programs both at the product-specific level and at various broader levels. For 
example, we have patent coverage for LNP-encapsulated mRNAs having specific chemical modification suited for vaccine and 
therapeutic mRNA use. Our estate also includes IP covering certain LNP-encapsulated mRNAs coding for infectious disease antigens 
for use in preventing or treating infectious diseases, including those caused by respiratory and latent viruses, as well as bacterial, viral 
and parasitic diseases known to threaten public health. Our mRNA chemistry, formulation and manufacturing patent applications and 
related know-how, along with trade secrets, may also provide us with additional IP protection relating to our development candidates.
Respiratory vaccines
For our respiratory vaccines programs, we have pursued patent protection featuring composition of matter and method of use claims. 
Where we may pursue patent protection may vary based on the unique geographic prevalence of various infectious diseases.
We have filed several patent applications covering our betacoronavirus vaccine program. We are pursuing patent protection for both 
our existing and next generation betacoronavirus vaccines. A non-exhaustive list of granted patents covering our COVID vaccine can 
be found in the following table.

Influenza
We have multiple patent families spanning different levels of breadth, design and antigen valency pending in the U.S., Europe and 
around the world, including several granted patents.
hMPV
Human metapneumovirus (hMPV) is a single-stranded RNA virus that is used in a combination program. We have patent applications 
covering our hMPV vaccine pending in the U.S. and Europe, with a granted patent in the U.S.
Latent vaccines
We have vaccine programs and patent applications directed to diseases caused by various latent viruses, including CMV, EBV, HSV 
and VZV, in some cases, using both preventative vaccines targeting the acute phase and therapeutic vaccines for treating the latent 
diseases in those who do become infected.
CMV
The patent coverage for our human CMV vaccine candidate is extensive and is based on a vaccine with six mRNAs encoding a 
pentamer surface glycoprotein complex and the gB surface glycoprotein. Both pentamer and gB facilitate entry of the virus into 
different cell types and therefore immune responses targeting these proteins can block virus entry, spread and reactivation. The current 
patent portfolio contains both compositions of matter and methods of treating subjects using the vaccine. In the U.S., our CMV 
vaccine is covered by multiple issued U.S. patents of differing breadth. Each family has counterparts consisting of pending 
applications and issued patents in non-U.S. jurisdictions, including, in some cases, Europe and Japan. A separate family of CMV 
patents, which includes mRNA-1647 plus mRNA-1443 for use in CMV vaccines for transplant indications, is also yielding patents 
and applications in foreign jurisdictions are pending.
EBV, HSV and VZV
Similar to CMV, we have filed patent applications, and in some cases multiple patent families, for each of EBV, HSV and VZV, e.g., 
covering prophylactic and/or therapeutic indications. In addition to patent applications filed in the United States, certain of these patent 
families have foreign counterparts, such as in Europe.

Public health vaccines
We maintain a multi-program effort at developing vaccines for potential future pandemics and for use in parts of the world with less 
well-established health care systems. This group of programs include infectious diseases such as flaviviruses such as Zika and dengue 
viruses, HIV, Nipah virus, and the Mpox virus. In addition, programs are ongoing in many bacterial diseases. While patent 
applications are filed on some potential public health targets, in some scenarios, platform patents rather than target specific patents 
may be used to provide patent protection for public health target vaccines.
INT
Composition of matter and method claims are being pursued to protect programs within our oncology therapeutics franchise. 
Proprietary methods around the making and therapeutic use of our INTs and resulting vaccine compositions are described and claimed 
in one granted U.S. patent, eight pending U.S. patent applications, six pending European patent applications, one granted patent and 
five pending patent applications in Japan, three pending patent applications and one granted patent in China, and several pending 
patent applications in New Zealand, South Africa, Asian and South American countries, as well as one PCT application. These 
applications also relate to various vaccine design formats, in particular, polyepitopic vaccine formats, and methods of treating cancer 
with such INTs. We also possess substantial know-how and trade secrets relating to the development and commercialization of our 
cancer vaccine programs, including related manufacturing process and technology.
Rare diseases
We have programs featuring expression of therapeutic proteins, e.g., intracellular enzymes for the treatment of rare diseases. For our 
rare disease programs, we generally pursue patent protection featuring composition of matter and method of use claims, for example, 
pharmaceutical composition and method of treatment claims. We have patent applications granted, pending and/or published for our 
most advanced rare disease development candidates targeting PA and MMA. In addition, we have patent applications granted, pending 
and/or published for our other rare disease candidates targeting Glycogen Storage Disorder, Type 1a (GSD1a), PKU, Crigler-Najjar 
Syndrome Type 1 (CN-1) and ornithine transcarbamylase deficiency (OTC).
Any U.S. and foreign patents that may issue from these patent families would be expected to expire in 2036 for the earliest of the 
MMA patents and 2038 to 2042 for the remaining MMA, PA, PKU, GSD1a and CN-1 patents, excluding any patent term adjustments, 
any patent term extensions and any terminal disclaimers.
As further described below, as we continue the development of our intended products, we continue to identify additional means of 
protecting our assets that would potentially enhance commercial success, including possible patent protection for additional methods 
of use, formulation, or manufacture.
Cystic fibrosis
Our CF development candidate is covered by pending U.S., European and PCT patent applications.
Gene editing
Our gene editing program currently has one filed patent family that includes issued patents in the U.S., Europe and Japan, and also 
pending applications in these jurisdictions. We plan to file patent applications on development candidates and other aspects of gene 
editing technology as we continue to innovate both internally and through strategic collaborations.
Trademarks
Our trademark portfolio currently contains at least 1,250 trademark registrations, including at least 30 registrations in the United States 
and the remaining in Canada, the European Union, the United Kingdom, Israel, China, Japan, Australia, and elsewhere. In addition, we 
have at least 360 pending trademark applications in more than 55 jurisdictions, including in the aforementioned locations and 
additional countries throughout Africa, Asia, and South America.
In-licensed intellectual property
While we develop and manufacture our potential mRNA medicines using our internally created mRNA technology platform, we also 
seek out and evaluate third party technologies and IP that may be complementary to our platform.

Patent sublicense agreements with Cellscript and mRNA RiboTherapeutics
The Trustees of the University of Pennsylvania owns several issued U.S. patents, granted European patents and pending U.S. patent 
applications directed, in part, to nucleoside-modified mRNAs and their uses (the Penn Modified mRNA Patents). mRNA 
RiboTherapeutics, Inc. (MRT) obtained an exclusive license to the Penn Modified mRNA Patents and granted its affiliate, Cellscript, 
LLC (Cellscript), a sublicense to the Penn Modified mRNA Patents in certain fields of use.
In June 2017, we entered into two sublicense agreements, one with Cellscript, and one with MRT, which agreements we collectively 
refer to as the Cellscript-MRT Agreements. Together, the Cellscript-MRT Agreements grant us a worldwide, sublicensable sublicense 
to the Penn Modified mRNA Patents to research, develop, make, and commercialize products covered by the Penn Modified mRNA 
Patents (licensed products), for all in vivo uses in humans and animals, including therapeutic, prophylactic, and diagnostic 
applications. The Cellscript-MRT Agreements are non-exclusive, although Cellscript and MRT are subject to certain time restrictions 
on granting additional sublicenses for in vivo uses in humans under the Penn Modified mRNA Patents. The Cellscript-MRT 
Agreements require us to pay royalties based on annual net sales of licensed products at rates in the low single digits for therapeutic, 
prophylactic, and diagnostic uses, and royalties based on annual net sales of licensed products sold for research uses at rates in the 
mid-single digits, subject to certain reductions, with an aggregate minimum floor.
The Cellscript-MRT Agreements will terminate upon the expiration or abandonment of the last to expire or become abandoned of the 
Penn Modified mRNA Patents. Cellscript or MRT, as applicable, may terminate its respective Cellscript-MRT Agreement if we fail to 
make required payments or otherwise materially breach the applicable agreement, subject to specified notice and cure provisions. 
Cellscript or MRT, as applicable, may also terminate the applicable Cellscript-MRT Agreement upon written notice in the event of our 
bankruptcy or insolvency or if we challenge the validity or enforceability of the Penn Modified mRNA Patents. We have the right to 
terminate each Cellscript-MRT Agreement at will upon 60 days’ prior notice to Cellscript or MRT, as applicable, provided that we 
cease all development and commercialization of licensed products upon such termination. If rights to MRT or Cellscript under the 
Penn Modified mRNA Patents are terminated (e.g., due to bankruptcy of MRT or Cellscript), the terminated party will assign its 
interest in the respective Cellscript-MRT Agreement to the licensor from which it received rights under the Penn Modified mRNA 
Patents and our rights will continue under the new licensor.
Patent license agreements with NIAID
In December 2022, we entered into a non-exclusive patent license agreement with the National Institute of Allergy and Infectious 
Diseases (NIAID), an Institute or Center of the National Institutes of Health (NIH), to license certain patent rights concerning 
stabilizing prefusion coronavirus spike proteins and the resulting stabilized proteins for use in COVID vaccine products. Pursuant to 
the agreement, we have agreed to pay low single-digit royalties on future net sales, a minimum annual royalty payment and certain 
contingent development, regulatory and commercial milestone payments on a licensed product-by-licensed product basis.
In January 2025, we entered into a non-exclusive patent license agreement with NIAID to license certain patent rights concerning 
prefusion RSV F proteins and their use. Pursuant to the agreement, we have agreed to pay tiered, low-to-mid single-digit royalties on 
net sales of our RSV vaccine, a minimum annual royalty payment, and certain contingent development, regulatory and commercial 
milestone payments on a licensed product-by-licensed product basis.  
Formulation technology in-licenses
Our development candidates use internally developed formulation technology that we own. We do, however, have rights to use and 
exploit multiple issued and pending patents covering formulation technologies under licenses from other entities. If in the future we 
elect to use or to grant our strategic collaborators sublicenses to use these in-licensed formulation technologies, we or our strategic 
collaborators may be liable for milestone and royalty payment obligations arising from such use. We consider the commercial terms of 
these licenses and their provisions regarding diligence, insurance, indemnification and other similar matters, to be reasonable and 
customary for our industry.
HUMAN CAPITAL
We had approximately 5,800 full-time employees in 18 countries as of December 31, 2024. We operate in a highly competitive 
environment for talent, particularly as we seek to attract and retain talent with experience in the biotechnology and pharmaceutical 
sectors. Our workforce is highly educated, and as of December 31, 2024, 43% of our employees hold Ph.D., Doctorate, M.D., J.D. or 
Master’s degrees. Among our employees, as of December 31, 2024, 49% are female. Among our leadership (which we define as 
employees at the vice president level and above), as of December 31, 2024, approximately 38% are female. 45% of our U.S. 
employees identify as racially or ethnically diverse as of December 31, 2024. In 2024, for the third year in a row, an outside statistical 
pay equity analysis confirmed zero statistically significant differences in pay across gender globally and across gender, race and 
ethnicity in the United States.

Our approach to attracting and retaining talent 
We are committed to ensuring that our employees find that their careers at Moderna are filled with purpose, growth and fulfillment. 
We believe that a career at Moderna provides opportunity for:
•
Impact: Our people will have the opportunity to do work that is unparalleled in terms of its innovation and scope of impact on 
people’s lives.
•
Growth: We provide incredible opportunities for growth and we obsess over learning (as demonstrated, in part, by our Mindsets 
(see below). We invest substantially in the development of our people. 
•
Well-being: We are committed to the health and well-being of our employees and their families and provide numerous family-
friendly benefits and opportunities to be healthy, including monthly contributions to employee lifestyle spending accounts.
•
Inclusion: We believe in the benefits of bringing together a diverse set of perspectives and backgrounds, and creating an 
environment where differences are celebrated and leveraged. We measure and hold management accountable to creating an 
environment where everyone's voice is heard.
•
Compelling rewards: To attract and retain the best talent, we provide competitive rewards that help to drive groundbreaking 
work and allow employees to share in the value we will create together, including through our equity programs.
•
Giving and volunteering: Our people have the opportunity to give back to their communities and directly support causes that 
they are passionate about through volunteer and employee matching donation programs.
To help promote alignment between our employees and our shareholders, all employees participate in our corporate equity programs 
through the receipt of equity awards, and the percentage of equity as a component of overall pay mix increases with seniority. We also 
allow our employees to select how they want the value of their award to be split between stock options and restricted stock units 
(RSUs). We believe that in addition to incentivizing growth that leads to shareholder value, broad eligibility for our equity programs 
further embeds our "We behave like owners" mindset and helps promote employee retention as these awards generally vest over a 
four-year period.
None of our employees have entered into a collective bargaining agreement with us. A small number of employees in France, Italy and 
Spain are covered by statutory collective bargaining agreements governing certain benefits and working conditions. Employees in our 
Madrid work center are represented by a works council. None of our other employees are represented by a labor union or a works 
council. We consider our employee relations to be good.
We believe that our employees are highly engaged, and our company and team have been publicly recognized for our leadership, 
innovation and good corporate citizenship. Science magazine ranked us as a top employer for each of the last ten years. Additionally, 
in 2024, Biospace ranked us the number one large employer in its 2025 Best Places to Work in Biopharma report for the fourth 
consecutive year. We also received a perfect score from the Human Rights Campaign's Corporate Equality Index for 2025. We 
measure employee engagement through a vendor-supplied engagement software, using validated external benchmarks to track 
employee engagement factors.
We continually monitor employee turnover rates, as our success depends upon retaining our highly trained personnel. We believe that 
the competitive compensation we offer, along with the combination of the factors listed above, among other factors, have helped 
reduce voluntary turnover. In 2024, our voluntary turnover rate was approximately 6%.
Our approach to training our employees
To further invest in our teams, we have established a structured training curriculum for our employees so that every employee 
becomes deeply familiar with our core technology and technologies that might further enable our innovation. In addition, we are 
focused on creating strong leaders through various management and leadership trainings. We have also built an online library of 
videos of a variety of scientific material that our employees can access flexibly. This content includes presentations by external 
speakers at in-house scientific seminars, scientific courses at external universities and peer-to-peer video series in which in-house 
experts provide an introductory view of complex topics they tackle within their teams.
New employees participate in our Moderna ONE onboarding program, which is an interactive learning experience designed to 
immerse our people in our culture and Mindsets from day one. Following onboarding, our employees continue to learn throughout 
their careers at Moderna and we deploy a digital learning management system to track and administer training programs for each of 
employee. 
In December 2021, we launched our Artificial Intelligence (AI) Academy. The AI Academy is intended to educate and empower our 
employees to identify and integrate AI and machine learning solutions into every Moderna system and process to bring mRNA 
medicines to patients. In 2024, we enhanced the AI Academy with a required GPT training to empower employees to transform the 
way they work with the power of AI.

Our culture
As an organization, we are bold, collaborative, curious and relentless. These values are underpinned by a core set of what we call 
“basecamp” values— integrity, quality, respect. Additionally, with the continued rapid growth of our company, we articulated the 
Moderna Mindsets, which define how we behave, lead and make decisions. We believe our Mindsets will be integral to our future 
success, and we integrate them into every facet of how we identify, onboard, grow and manage our talent.  
To further develop and retain our workforce, we conduct periodic talent reviews that identify key talent within the organization. We 
use that data to inform specific development opportunities for key current and potential future leaders, and to support our periodic 
succession planning activities for key roles. These steps together ensure we have a robust understanding of our workforce and a talent 
pipeline to grow future leaders, and provide our employees an opportunity to continuously grow and advance in a way that meets their 
aspirations and talents.
CORPORATE SOCIAL RESPONSIBILITY 
As we pursue our mission to deliver the greatest possible impact to people through mRNA medicines, we have developed a corporate 
social responsibility (CSR) program that demonstrates our commitment to patients, employees, the environment and local 
communities. Our CSR framework consists of five key focus areas: medicines for patients, community, governance and ethics, 
employees and environment. Please refer to our 2023 ESG Report under the “Responsibility—Corporate policies” section of our 
website, which can be found at www.modernatx.com/responsibility/corporate-policies, as well as our proxy statement related to our 
2025 Annual Meeting of Stockholders that we will file with the SEC, for a description of some of the measures we have taken to 
progress our commitment to corporate social responsibility.
COMPETITION
The biotechnology and pharmaceutical industries utilize rapidly advancing technologies and are characterized by intense competition. 
There is also a strong emphasis on defense of intellectual property and proprietary products. 
mRNA Medicines 
We believe that mRNA as a medicine coupled with our capabilities across mRNA technology, drug discovery, development and 
manufacturing provide us with a competitive advantage. However, we face competition from others developing mRNA vaccines and 
therapeutics, as well as other medicines that compete or could compete with our products. We face competition from various sources, 
including large pharmaceutical companies, biotechnology companies, academic institutions, government agencies and public and 
private research institutions. The continued growth of the mRNA field is leading to increased competitive pressure, including from 
large and more established pharmaceutical companies. We also face competition when entering into strategic alliances to advance and 
grow our pipeline. 
We largely compete against Pfizer and BioNTech for sales of our COVID vaccine, whose vaccine is also based on mRNA technology. 
We also compete against other vaccines, including Sanofi and Novavax’s. Other companies and academic institutions are conducting 
research on, and may develop, vaccines against COVID or other coronaviruses that could compete with our vaccine. Additionally, 
some competitors have developed COVID treatments, including Pfizer’s antiviral pill, and the existence of such treatments may 
reduce demand for vaccines. With respect to our RSV vaccine, we compete against Pfizer and GlaxoSmithKline, who entered the U.S. 
market prior to us and achieved larger market shares in 2024. Unlike 2024, we expect to participate in the full contracting season in 
the United States in 2025, and our goal is to increase our market share in the United States and market access globally.  
Competition for the sale of our products is impacted by many factors, including, among others, actual and perceived vaccine efficacy, 
safety and tolerability, perceptions of mRNA technology, storage and handling conditions and the relative ease of distribution and 
administration, the timing and scope of regulatory approvals, reimbursement coverage and production and distribution costs. 
In markets that we enter after competitors have already introduced a competing product, we may have difficulty achieving market 
share, as was the case in connection with the launch of our RSV vaccine. See “Risk Factors—The vaccines market, and 
pharmaceutical market more generally, is intensely competitive, and we may not compete effectively in the market for existing or new 
products, treatment methods or technologies.”
There are additional companies working on mRNA medicines, some of which have reached commercialization. These companies 
include BioNTech, Pfizer, Sanofi and GlaxoSmithKline in collaboration with CureVac.

Our Collaborations 
We and our strategic collaborators also face competition in other therapeutic areas beyond the field of mRNA medicines. These 
competitors include a growing number of pharmaceutical, biotechnology and academic institutions researching and developing 
therapies (e.g., CAR-T) against which we could compete in the future. Potentially competitive products are at various stages of 
development.   
GOVERNMENT REGULATION
Government authorities in the United States at the federal, state and local level and in other countries and regions, such as in the EU 
regulate, among other things, the research, development, manufacture and marketing of our products. Generally, before a new 
medicine can be marketed, considerable data demonstrating its quality, safety and efficacy must be obtained and submitted for review 
and approved by the competent regulatory authority.
U.S. drug and biological product development
In the United States, the FDA regulates drugs under the Federal Food, Drug, and Cosmetic Act (FDCA) and biologics under the 
FDCA, the Public Health Service Act (PHSA), each in conjunction with their implementing regulations. Both drugs and biologics also 
are subject to other federal, state and local statutes and regulations. Failure to comply with applicable U.S. requirements at any time 
during the product development process, approval process or following approval may subject us to administrative or judicial sanctions. 
These sanctions could include, among other actions, the FDA’s refusal to approve pending applications, license revocation, a clinical 
hold, untitled or warning letters, product recalls, market withdrawals, product seizures, total or partial suspension of production or 
distribution, injunctions, fines, refusals of government contracts, restitution, disgorgement and civil or criminal penalties. 
Any of our product candidates must be approved by the FDA through a BLA or new drug application (NDA), or supplemental BLA or 
supplemental NDA, process before they may be legally marketed in the United States. 
Preclinical studies
Before any of our development candidates may be tested in humans, the development candidate must undergo rigorous preclinical 
testing. Preclinical studies include laboratory evaluation of product chemistry and formulation, as well as in vitro and animal studies to 
assess the potential for adverse events and in some cases to establish a rationale for therapeutic use. The conduct of preclinical studies 
is subject to federal regulations and requirements, including GLP regulations for safety/toxicology studies. An IND sponsor must 
submit the results of the preclinical tests, together with manufacturing information, analytical data, any available clinical data or 
literature and plans for clinical studies, among other things, to the FDA as part of an IND. An IND is a request for authorization from 
the FDA to administer an investigational product to humans and must become effective before human clinical trials may begin. Unless 
the FDA raises concerns, an IND automatically becomes effective 30 days after receipt by the FDA. In such a case, the IND sponsor 
and the FDA must resolve any outstanding concerns before the clinical trial can begin. 
Clinical trials
The clinical stage of development involves the administration of the investigational medicine to healthy volunteers or patients under 
the supervision of qualified investigators and in accordance with GCP requirements. Clinical trials are conducted under protocols 
detailing, among other things, the objectives of the clinical trial, dosing procedures, subject selection and exclusion criteria and the 
parameters to be used to monitor subject safety and assess efficacy. Each protocol, and any subsequent amendments to the protocol, 
must be submitted to the FDA as part of the IND. Furthermore, each clinical trial must be reviewed and approved by an Institutional 
Review Board (IRB) for each institution at which the clinical trial will be conducted to ensure that the risks to individuals participating 
in the clinical trials are minimized and are reasonable in relation to anticipated benefits. The IRB also approves the informed consent 
form that must be provided to clinical trial subjects and monitors the clinical trial until completed. Further, progress reports detailing 
the results of the clinical trials, among other information, must be submitted at least annually to the FDA and more frequently in other 
situations, including the occurrence of serious adverse events. Information about certain clinical trials must be submitted within 
specific timeframes for publication on the www.clinicaltrials.gov website.
Under the U.S. National Institutes of Health Guidelines for Research Involving Recombinant DNA Molecules (NIH Guidelines), 
supervision of human gene transfer trials includes evaluation and assessment by an institutional biosafety committee (IBC), a local 
institutional committee that reviews and oversees research utilizing recombinant or synthetic nucleic acid molecules at that institution. 
While the NIH Guidelines are only mandatory for research being conducted at or sponsored by institutions receiving NIH funding of 
recombinant or synthetic nucleic acid molecule research, many companies and other institutions not otherwise subject to the NIH 
Guidelines voluntarily follow them.

Foreign studies conducted under an IND must meet the same requirements that apply to studies being conducted in the United States. 
Data from a foreign study not conducted under an IND may be submitted in support of a BLA if the study was conducted in 
accordance with GCP requirements, and the FDA is able to validate the data.
Clinical trials generally are conducted in three sequential phases, which may overlap:
•
Phase 1 clinical trials generally involve a small number of healthy volunteers or disease-affected patients to assess the 
metabolism, pharmacologic action, side effect tolerability, and safety of the investigational medicine.
•
Phase 2 clinical trials generally involve disease-affected patients to evaluate proof of concept and/or determine the dosing 
regimen(s) for subsequent investigations. At the same time, safety and further pharmacokinetic and pharmacodynamic 
information is collected, possible adverse effects and safety risks are identified, and a preliminary evaluation of efficacy is 
conducted.
•
Phase 3 clinical trials generally involve a large number of disease-affected patients at multiple sites and are designed to provide 
the data necessary to demonstrate the effectiveness of the investigational medicine for its intended use, its safety in use and to 
establish the overall benefit/risk relationship of the investigational medicine, and provide an adequate basis for product labeling.
The FDA may also require post-approval Phase 4 non-registrational studies to explore scientific questions to further characterize 
safety and efficacy during commercial use of a drug.
The FDA or the clinical trial site may suspend or terminate a clinical trial at any time on various grounds, including a finding that the 
patients are being exposed to an unacceptable health risk. Similarly, an IRB can suspend or terminate approval of a clinical trial at its 
institution if the clinical trial is not being conducted in accordance with the IRB’s requirements or if the drug or biologic has been 
associated with unexpected serious harm to patients. Additionally, some clinical trials are overseen by an independent group of 
qualified experts organized by the clinical trial sponsor, known as a data safety monitoring board or committee. This group provides 
authorization for whether a clinical trial may move forward at designated check points based on access to certain data from the clinical 
trial. 
FDA review process
Following completion of the clinical trials, data are analyzed to assess whether the investigational product is safe and effective for the 
proposed indicated use or uses. The results of preclinical studies and clinical trials are then submitted to the FDA as part of a BLA or 
NDA, along with proposed labeling, chemistry, and manufacturing information to ensure product quality and other relevant data. A 
BLA is a request for approval to market a biologic for one or more specified indications and must contain proof of the biologic’s 
safety, purity, and potency. An NDA for a new drug must contain proof of the drug’s safety and efficacy. To support marketing 
approval, the data submitted must be sufficient in quality and quantity to establish the safety and efficacy of the investigational 
product to the satisfaction of the FDA. FDA approval of a BLA or NDA must be obtained before a biologic or drug may be marketed 
in the United States. 
Before approving a BLA or NDA, the FDA will conduct a pre-approval inspection of the manufacturing facilities for the new product 
to determine whether the facilities comply with cGMP requirements and are adequate to assure consistent production of the product 
within required specifications. The FDA also may audit data from clinical trials to ensure compliance with GCP requirements. 
Additionally, the FDA may refer applications for novel products or products which present difficult questions of safety or efficacy to 
an advisory committee of expert advisors for review, evaluation and a recommendation as to whether the application should be 
approved and under what conditions, if any. The committee makes a recommendation to the FDA that is not binding but is generally 
followed. 
After the FDA evaluates a BLA or NDA, it will grant marketing approval, request additional information or issue a complete response 
letter (CRL) outlining the deficiencies in the submission. The CRL may require additional testing or information, including additional 
preclinical or clinical data, for the FDA to reconsider the BLA or NDA. Even if such additional information and data are submitted, 
the FDA may decide that the BLA or NDA still does not meet the standards for approval. If the FDA grants approval, it issues an 
approval letter that authorizes commercial marketing of the product with specific prescribing information for specific indications.
Orphan drug designation
Under the Orphan Drug Act, the FDA may grant orphan designation to a drug or biologic product intended to treat a rare disease or 
condition, which is generally a disease or condition that affects fewer than 200,000 individuals in the United States, or more than 
200,000 individuals in the United States and for which there is no reasonable expectation that the cost of developing and making the 
product available in the United States for this type of disease or condition will be recovered from sales of the product. 
If a product that has orphan designation subsequently receives the first FDA approval for the disease or condition for which it has such 
designation, the product is entitled to orphan drug exclusivity, which means that the FDA may not approve any other applications to 
Table of Contents
38

market the same drug for the same indication for seven years from the date of such approval, except in very limited circumstances, 
such as if the latter product is shown to be clinically superior to the orphan product. 
Expedited development and review programs
The FDA may employ one of several tools to facilitate and expedite the development and review of a medicine, including fast track 
designation, breakthrough therapy designation, accelerated approval and priority review designation. Fast track designation is 
designed to facilitate the development and review of a medicine that treats a serious condition and fills an unmet medical need. 
Breakthrough therapy designation is designed to expedite the development and review of a medicine that treats a serious condition and 
preliminary clinical evidence demonstrates substantial improvement over available therapies. Priority review designation means the 
FDA’s goal is to take action on an application within six months of filing. The FDA may grant priority review designation to a 
medicine that would provide significant improvement in the safety or effectiveness of a treatment, diagnosis or prevention of a serious 
condition.
A product may also be eligible for accelerated approval if it treats a serious or life-threatening condition and generally provides a 
meaningful advantage over available therapies. In addition, such product must demonstrate an effect on a surrogate endpoint that is 
reasonably likely to predict clinical benefit or on a clinical endpoint that can be measured earlier than irreversible morbidity or 
mortality (IMM) that is reasonably likely to predict an effect on IMM or other clinical benefit. As a condition of approval, the FDA 
may require that a sponsor of a drug or biologic receiving accelerated approval perform adequate and well-controlled post-marketing 
clinical trials with due diligence. If the FDA concludes that a drug or biologic shown to be effective can be safely used only if 
distribution or use is restricted, it will require such post-marketing restrictions, as it deems necessary to assure safe use of the product. 
Under the Food and Drug Omnibus Reform Act of 2022 (FDORA), the FDA is now permitted to require, as appropriate, that such 
trials be underway prior to approval or within a specific time period after the date of approval for a product granted accelerated 
approval. Additionally, under FDORA, the FDA has increased authority for expedited procedures to withdraw its accelerated approval 
for such drug or biologic if, for example, the confirmatory trial fails to verify the predicted clinical benefit of the product.
Even if a product qualifies for one or more of these programs, the FDA may later decide that the product no longer meets the 
conditions for qualification or that the time period for FDA review or approval may not be shortened. Furthermore, fast track 
designation, priority review, accelerated approval, and breakthrough therapy designation do not change the standards for approval.
Emergency Use Authorization (EUA)
The Secretary of Health and Human Services (HHS) may authorize unapproved medical products to be marketed in the context of an 
actual or potential emergency that has been designated by the U.S. government. The COVID-19 pandemic has been designated as such 
an emergency. After an emergency has been announced, the Secretary of HHS may authorize the issuance of and thereafter, the FDA 
Commissioner may issue EUAs for the use of specific products based on certain criteria, including that the product may be effective in 
diagnosing, treating, or preventing serious or life-threatening diseases when there are no adequate, approved, and available 
alternatives. An EUA terminates when the emergency determination underlying the EUA terminates. An EUA is not a long-term 
alternative to obtaining FDA approval, licensure, or clearance for a product. The FDA may revoke an EUA for a variety of reasons, 
including if the underlying health emergency no longer exists or warrants such authorization.
In the United States, the Public Readiness and Emergency Preparedness Act (PREP Act) provides immunity for manufacturers from 
all claims under state or federal law for “loss” arising out of the administration or use of a “covered countermeasure.” However, 
injured persons may still bring a suit for “willful misconduct” against the manufacturer under some circumstances. “Covered 
countermeasures” include “qualified pandemic or epidemic products,” including products intended to diagnose or treat pandemic or 
epidemic disease, such as pandemic vaccines. For these immunities to apply, the Secretary of HHS must issue a declaration in cases of 
public health emergency or “credible risk” of a future public health emergency. On March 17, 2020, the Secretary of HHS issued a 
declaration under the PREP Act and has issued subsequent amendments thereto to provide liability immunity for activities related to 
certain countermeasures against COVID-19. While we believe our products sold to the U.S. Government will continue to be covered 
under the provisions of the PREP Act, this cannot be assured.
Pediatric information
Under the Pediatric Research Equity Act of 2003, all marketing applications for new active ingredients, indications, dosage forms, 
dosing regimens or routes of administration must contain an assessment of the safety and effectiveness of the product for the claimed 
indication in pediatric patients unless this requirement is waived, deferred or inapplicable.
Under the Best Pharmaceuticals for Children Act, a product may be eligible for pediatric exclusivity, which adds six months to 
existing exclusivity periods and patent terms. This exclusivity may be granted based on the voluntary completion of a pediatric study 
in accordance with an FDA-issued written request for such a study.

Post-approval requirements
Following approval of a new product, the manufacturer and the approved product are subject to continuing regulation by the FDA, 
including, among other things, monitoring and record-keeping activities, reporting of adverse experiences, complying with promotion 
and advertising requirements, and limitations on industry-sponsored scientific and educational activities. Although physicians may 
prescribe legally available products for off-label uses, manufacturers may not market or promote such uses. Prescription drug and 
biologic promotional materials must be submitted to the FDA in conjunction with their first use. Further, if there are any modifications 
to the drug or biologic, including changes in indications, labeling or manufacturing processes or facilities, the applicant may be 
required to submit and obtain FDA approval of a new BLA or NDA or BLA or NDA supplement, which may require the development 
of additional data or preclinical studies and clinical trials.
The FDA may also place other conditions on approvals including the requirement for a Risk Evaluation and Mitigation Strategy 
(REMS) to assure that the benefits of the product outweigh the risks. A REMS could include medication guides, physician 
communication plans, or elements to assure safe use, such as restricted distribution methods, patient registries, and other risk 
minimization tools. Newly discovered or developed safety or effectiveness data may require changes to a product’s approved labeling, 
including the addition of new warnings and contraindications, and also may require the implementation of other risk management 
measures, including a REMS or the conduct of post-marketing studies to assess a newly discovered safety issue. Product approvals 
may be withdrawn for non-compliance with regulatory standards, or if problems occur following initial marketing.
FDA regulations require that products be manufactured in specific approved facilities and in accordance with cGMP regulations. 
Entities involved in the manufacture and distribution of approved drugs or biologics and their third-party manufacturers must comply 
with cGMP regulations that require, among other things, quality control and quality assurance, the maintenance of records and 
documentation, and the obligation to investigate and correct any deviations from cGMP. Such entities are required to register their 
establishments with the FDA and certain state agencies, and are subject to periodic unannounced inspections for compliance with 
cGMP requirements and other laws. The discovery of violations could result in enforcement actions, and the discovery of problems 
with a product after approval may result in restrictions on a product, manufacturer, or holder of an approved BLA or NDA, including 
recall.
U.S. patent term restoration and regulatory data exclusivity
In certain circumstances, some U.S. patents may be eligible for limited patent term extension under the Drug Price Competition and 
Patent Term Restoration Act of 1984, commonly referred to as the Hatch Waxman Amendments. The Hatch Waxman Amendments 
permit restoration of the patent term of up to five years as compensation for patent term lost during product development and FDA 
regulatory review process. Patent term restoration, however, cannot extend the remaining term of a patent beyond a total of 14 years 
from the product’s approval date. The patent term restoration period is generally one half the time between the effective date of an 
IND and the submission date of a BLA or NDA, plus the time between the submission date of a BLA or NDA and the approval of that 
application. Only one patent applicable to an approved product is eligible for such an extension and the application for the extension 
must be submitted prior to the expiration of the patent. The USPTO, in consultation with the FDA, reviews and approves the 
application for any patent term extension or restoration.
If the FDA approves a drug product that contains an active ingredient not previously approved, the product is typically entitled to five 
years of non-patent regulatory data exclusivity. Other products may be entitled to three years of regulatory data exclusivity if approval 
was based on the FDA’s reliance on new clinical studies essential to approval submitted by the NDA applicant. If the NDA applicant 
studies the product for use by children, the FDA may grant pediatric exclusivity, which extends by 180 days each existing exclusivity 
(patent and regulatory) related to the product. 
An abbreviated approval pathway for biological products shown to be biosimilar to, or interchangeable with, an FDA-licensed 
reference biological product was created by the Biologics Price Competition and Innovation Act of 2009 (the BPCI Act). Biosimilarity 
requires a showing that the product is “highly similar” to the reference product notwithstanding minor differences in clinically inactive 
components and that there are no clinically meaningful differences between the product and the reference product in terms of safety, 
purity, and potency. Interchangeability requires that a biological product be biosimilar to the reference product and that the product 
can be expected to produce the same clinical results as the reference product in any given patient and, for products administered 
multiple times to an individual, that the product and the reference product may be alternated or switched after one has been previously 
administered without increasing safety risks or risks of diminished efficacy relative to exclusive use of the reference biological 
product. A reference biological product is granted 12 years of regulatory data exclusivity from the time of first licensure of the product 
and the FDA will not accept an application for a biosimilar or interchangeable product based on the reference biological product until 
four years after the date of first licensure of the reference product.

Drug development in the European Economic Area (EEA)
Medicinal products can be marketed in the EEA, which is comprised of the 27 Member States of the EU and Norway, Iceland and 
Liechtenstein, only if a marketing authorization from the competent regulatory authority has been obtained. Similar to the United 
States, the various phases of preclinical and clinical research in the EU/EEA are subject to significant regulatory controls. Effective 
since January 2022, the Clinical Trials Regulation (EC) No. 536/2014 aims to streamline and harmonize the procedures for assessment 
and governance of clinical trials throughout the EU and to require that information on the authorization, conduct and results of each 
clinical trial conducted in the EU be publicly available.
Pediatric investigation plan
An application for marketing authorization of a medicinal product for human use that is not yet authorized in the EU must include a 
Pediatric Investigational Plan (PIP) pursuant to the Regulation No. 1901/2006 on medicinal products for pediatric use (known as the 
Paediatric Regulation), unless a waiver applies. A scientific committee established at the European Medicines Agency (EMA), the 
Paediatric Committee (PDCO) assesses the content of any PIP, waivers, and deferrals for a medicinal product submitted to it and 
formulates an opinion thereon.
Review and approval process
In the EU/EEA, in order to obtain a marketing authorization from the applicable regulatory authority, a company may submit 
marketing authorization applications either under a centralized or decentralized procedure. The centralized procedure, which is 
compulsory for medicines produced by certain biotechnological processes, advanced therapy medicinal products (ATMPs), orphan 
medicinal products, or those medicines containing a new active substance and intended to treat specific diseases (HIV/AIDS, cancer, 
neurodegenerative disorders, diabetes, autoimmune and other immune dysfunctions and viral diseases), and optional for those 
medicines that are highly innovative or contain a new active substance, provides for the grant of a single marketing authorization that 
is valid throughout the EU/EEA. In addition to the centralized procedure, a marketing authorization can also be obtained in the EU/
EEA through a national procedure, which requires a separate application to and approval determination by each country; a 
decentralized procedure, whereby applicants submit identical applications to several countries and receive simultaneous approval; and 
a mutual recognition procedure, where applicants submit an application to one country for review and other countries may accept or 
reject the initial decision.
A conditional marketing authorization may be granted in the EU when comprehensive clinical data for the safety and efficacy of the 
medicinal product have not been supplied but all the following requirements are met: (i) the risk-benefit balance of the medicine is 
positive; (ii) it is likely that the applicant will be in a position to provide the comprehensive clinical data post-authorization; (iii) the 
medicine fulfills an unmet medical need; and (iv) the benefit to public health of the immediate availability on the market of the 
medicine outweighs the risk that additional data is still required. Conditional marketing authorizations are valid for one year, on a 
renewable basis. The marketing authorization holder will be required to fulfil specific obligations within certain timeframes, which 
may include completing ongoing trials or conducting new trials to confirm that the benefit-risk balance is positive. Once such 
obligations are fulfilled, provided the benefit-risk balance is still positive, a conditional marketing authorization can be converted into 
a standard marketing authorization.
European regulatory data protection
In the EU, new innovative products authorized for marketing qualify for regulatory data protection consisting of eight years of data 
exclusivity and an additional two years of market protection upon the grant of a marketing authorization. Data exclusivity prevents 
generic or biosimilar applicants from referencing the innovator’s data when applying for a generic or biosimilar marketing 
authorization. During the additional two-year period of market protection, a generic or biosimilar marketing authorization application 
can be submitted, and the innovator’s data may be referenced, but no generic or biosimilar product can be marketed until the 
expiration of the market protection period. There is no guarantee that a product will be considered by the EU’s regulatory authorities 
to be an innovative medicinal product, and products may not qualify for regulatory data protection.
European orphan designation and exclusivity
Orphan drug designation is available in the EU to promote the development of products that are intended for the diagnosis, prevention, 
or treatment of life threatening or chronically debilitating conditions affecting not more than five in 10,000 persons in the EU 
community, or where it is unlikely that the development of the medicine would generate sufficient return to justify the necessary 
investment in its development, and in each case for which no satisfactory method of diagnosis, prevention, or treatment has been 
authorized (or, if a method exists, the product would be a significant benefit to those affected). Medicinal products that receive and 
maintain orphan drug designation following approval are entitled to 10 years of market exclusivity, which protects against applications 
for and the grant of marketing authorizations for similar medicinal products in the same therapeutic indication. This period may be 
Table of Contents
41

reduced to six years if, at the end of the fifth year, it is established that the orphan drug designation criteria are no longer met. During 
the period of market exclusivity, marketing authorization may only be granted to a similar medicinal product for the same therapeutic 
indication if: (i) a second applicant can establish that its product, although similar to the authorized product, is safer, more effective or 
otherwise clinically superior; (ii) the marketing authorization holder for the authorized product consents to a second orphan medicinal 
product application; or (iii) the marketing authorization holder for the authorized product cannot supply enough orphan medicinal 
product 
The aforementioned EU rules are generally applicable in the EEA.
European data protection regulations
The EU General Data Protection Regulation (GDPR) governs the collection and use of personal data in the EU. The GDPR imposes 
strict requirements relating to the consent of the individuals to whom the personal data relates, the information provided to the 
individuals, the security and confidentiality of the personal data, data breach notification and the use of third-party processors in 
connection with the processing of the personal data. The GDPR also imposes strict rules on the transfer of personal data out of the EU, 
provides an enforcement authority and imposes large penalties for noncompliance, including the potential for fines of up to €20.0 
million or 4% of the annual global revenues of the infringer, whichever is greater. The GDPR also confers a private right of action on 
data subjects and consumer associations to lodge complaints with competent national data protection authorities, seek judicial 
remedies and obtain compensation for damages resulting from violations of the GDPR. Non-compliance could also result in the 
imposition of orders to stop data processing activities.
The UK has incorporated the GDPR into UK law (the UK GDPR). The UK GDPR and the UK Data Protection Act 2018 set out the 
UK’s data protection regime, which is independent from but aligned to the EU’s data protection regime. Although the UK is regarded 
as a third country under the EU’s GDPR, the European Commission has issued a decision recognizing the UK as providing adequate 
protection under the EU GDPR and, therefore, transfers of personal data originating in the EU to the UK remain unrestricted. Like the 
GDPR, the UK GDPR restricts personal data transfers outside the UK to countries not regarded by the UK as providing adequate 
protection. The UK government has confirmed that personal data transfers from the UK to the EEA remain free flowing. Non-
compliance with the UK GDPR may result in monetary penalties of up to £17.5 million or 4% of worldwide revenue, whichever is 
higher.
Marketing of medicines in the EU
Similar to the Anti-Kickback Statute prohibition in the United States discussed below, the provision of benefits or advantages to 
physicians to induce or encourage the prescription, recommendation, endorsement, purchase, supply, order, or use of medicinal 
products is prohibited in the EU. Infringement of relevant EU laws could result in substantial fines and imprisonment. Payments may 
be made to physicians in limited circumstances, and in certain EU Member States such payments must be publicly disclosed. 
Moreover, agreements with physicians for the provision of services often must be the subject of prior notification and approval by the 
physician’s employer, his or her competent professional organization, and/or the regulatory authorities of the individual EU Member 
States. These requirements are provided in the national laws, industry codes, or professional codes of conduct, applicable in the EU 
Member States. Failure to comply with these requirements could result in reputational risk, public reprimands, administrative 
penalties, fines, or imprisonment.
Rest of the world regulation
Outside of the United States and the EU, the requirements governing the conduct of clinical trials, product licensing, pricing, and 
reimbursement vary from country to country. If we fail to comply with such requirements, we may be subject to, among other things, 
fines, suspension or withdrawal of regulatory approvals, product recalls, seizure of products, operating restrictions, or criminal 
prosecution.
Coverage and reimbursement
Patients who are provided medical treatment for their conditions generally rely on third-party payors to reimburse all or part of the 
costs associated with their treatment. Coverage and adequate reimbursement from governmental healthcare programs, such as 
Medicare and Medicaid, and commercial payors is critical to new product acceptance. Government authorities and other third-party 
payors, such as private health insurers and health maintenance organizations, decide which drugs and treatments they will cover and 
the amount of reimbursement.
In the United States, no uniform policy of coverage and reimbursement for products exists among third-party payors. As a result, 
obtaining coverage and reimbursement approval of a product from a government or other third-party payor is a time-consuming and 
costly process that could require us to provide to each payor supporting scientific, clinical and cost-effectiveness data for the use of 
Table of Contents
42

our products on a payor-by-payor basis, with no assurance that coverage and adequate reimbursement will be obtained. In the United 
States, the principal decisions about reimbursement for new medicines are typically made by the Centers for Medicare & Medicaid 
Services (CMS). CMS decides whether and to what extent a new medicine will be covered and reimbursed under Medicare and private 
payors tend to follow CMS to a substantial degree. Even if we obtain coverage for a given product, the resulting reimbursement 
payment rates might not be adequate for us to achieve or sustain profitability or may require co-payments that patients find 
unacceptably high. Additionally, third-party payors may not cover, or provide adequate reimbursement for, long-term follow-up 
evaluations required following the use of product candidates, once approved. Patients are unlikely to use our product candidates, once 
approved, unless coverage is provided and reimbursement is adequate to cover a significant portion of their cost. There is significant 
uncertainty related to insurance coverage and reimbursement of newly approved products. It is difficult to predict at this time what 
third-party payors will decide with respect to the coverage and reimbursement for our product candidates.
Net prices for drugs may be reduced by mandatory discounts or rebates required by government healthcare programs or private payors 
and by any future relaxation of laws that presently restrict imports of drugs from countries where they may be sold at lower prices than 
in the United States. In addition, many pharmaceutical manufacturers must calculate and report certain price reporting metrics to the 
government, such as average sales price and best price. Penalties may apply in some cases when such metrics are not submitted 
accurately and timely.
We expect that healthcare reform measures that may be adopted in the future may result in more rigorous coverage criteria and in 
additional downward pressure on the price that we receive for any approved product. Additionally, legislative and regulatory proposals 
have been made to expand post-approval requirements and restrict sales and promotional activities for pharmaceutical products.
In addition, in some foreign countries, the proposed pricing for a drug must be approved before it may be lawfully marketed. The 
requirements governing drug pricing vary widely from country to country. For example, the EU provides options for its Member 
States to restrict the range of medicinal products for which their national health insurance systems provide reimbursement and to 
control the prices of medicinal products for human use. To obtain reimbursement or pricing approval, some of these countries may 
require the completion of clinical trials that compare the cost effectiveness of a particular product candidate to currently available 
therapies. A Member State may approve a specific price for the medicinal product or it may instead adopt a system of direct or indirect 
controls on the profitability of the company placing the medicinal product on the market. There can be no assurance that any country 
that has price controls or reimbursement limitations for pharmaceutical products will allow favorable reimbursement and pricing 
arrangements for any of our product candidates. Historically, products launched in the EU do not follow price structures of the United 
States and generally prices tend to be significantly lower.
For further information on certain risks associated with the pricing and reimbursement of our products see “Risk Factors—Sales of 
pharmaceutical products depend on the availability and extent of reimbursement from third-party payors, and we may be adversely 
impacted by changes to such reimbursement policies or rules.”
Other healthcare laws
Healthcare providers, physicians, and third-party payors, including governmental payors, such as Medicare and Medicaid in the United 
States, will play a primary role in the recommendation and prescription of any marketed products. Any arrangements with these 
parties implicate certain fraud and abuse and other healthcare laws and regulations. In the United States, these laws include, among 
others:
•
The Anti-Kickback Statute, which makes it illegal for any person to knowingly and willfully solicit, receive, offer, or pay any 
remuneration, directly or indirectly, in cash or in kind, that is intended to induce or reward referrals, including the purchase, 
recommendation, order or prescription of a particular drug or any other good or service, for which payment may be made under a 
federal healthcare program, such as Medicare or Medicaid. 
•
The federal False Claims Act, which imposes civil penalties, including through civil whistleblower or qui tam actions, against 
individuals or entities (including manufacturers) for, among other things, knowingly presenting, or causing to be presented, false 
or fraudulent claims for payment by a federal healthcare program or making a false statement or record material to payment of a 
false claim or avoiding, decreasing, or concealing an obligation to pay money to the federal government.
•
Health Insurance Portability and Accountability Act of 1996 (HIPAA), which imposes criminal and civil liability for, among other 
things, knowingly and willfully executing a scheme, or attempting to execute a scheme, to defraud any healthcare benefit 
program, including private payors, or falsifying, concealing, or covering up a material fact or making any materially false 
statements in connection with the delivery of or payment for healthcare benefits, items or services. 
•
HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009 (HITECH), and their 
respective implementing regulations, which impose, among other things, requirements on covered entities and their business 
associates relating to the privacy and security of individually identifiable health information. 
•
The Physician Payments Sunshine Act, enacted as part of the Patient Protection and Affordable Care Act (ACA), which requires 
certain pharmaceutical manufacturers with products reimbursed under certain government programs to disclose annually to the 
Table of Contents
43

federal government (for re-disclosure to the public) certain payments and other transfers of value provided to physicians, teaching 
hospitals and certain other licensed health care practitioners. 
•
Federal government price reporting laws, which require us to calculate and report complex pricing metrics in an accurate and 
timely manner to government programs.
•
Federal consumer protection and unfair competition laws, which broadly regulate marketplace activities and activities that 
potentially harm consumers.
•
Analogous state fraud and abuse laws and regulations, such as state anti-kickback and false claims laws, which may be broader in 
scope and apply regardless of payor. 
Additionally, certain state and foreign laws also govern the privacy and security of health information. Such data privacy and security 
laws may differ from each other in significant ways and often are not pre-empted by HIPAA, thus complicating compliance efforts. 
For example, the California Consumer Protection Act (CCPA) established a comprehensive privacy framework for covered businesses 
by creating an expanded definition of personal information, establishing new data privacy rights for consumers in the State of 
California, imposing special rules on the collection of consumer data from minors, and creating a new and potentially severe statutory 
damages framework for violations of the CCPA and for businesses that fail to implement reasonable security procedures and practices 
to prevent data breaches. Further, the California Privacy Rights Act (CPRA), which took effect on January 1, 2023, has established 
additional obligations with respect to processing and storing personal information. The CPRA significantly modified the CCPA, 
including by expanding customers' rights with respect to certain sensitive personal information. While clinical trial data and 
information governed by HIPAA are currently exempt from the current versions of the CCPA and CPRA, other personal information 
is applicable due to the CPRA’s broader scope. Similar laws have been passed or proposed in numerous other states.
The scope and enforcement of each of these laws is uncertain and subject to rapid change in the current environment of healthcare 
reform. 
Current and future healthcare reform legislation
In the United States and foreign jurisdictions, there have been a number of legislative and regulatory changes and proposed changes 
regarding the healthcare system that could prevent or delay marketing approval of our investigational medicines, restrict or regulate 
post-approval activities and affect our ability to profitably sell any approved products. The ACA, for example, contains provisions that 
subject biological products to potential competition by lower-cost biosimilars and may reduce the profitability of drug products 
through increased rebates for drugs reimbursed by Medicaid programs, extension of Medicaid rebates to Medicaid managed care 
plans, mandatory discounts for certain Medicare Part D beneficiaries and, annual fees based on pharmaceutical companies’ share of 
sales to federal health care programs. Current laws, as well as other healthcare reform measures that may be adopted in the future, may 
result in more rigorous coverage criteria and in additional downward pressure on the price for any approved products.
In the United States, it is unclear whether the ACA will be overturned or further amended. We cannot predict what effect further 
changes to the ACA would have on our business. Additionally, other federal health reform measures have been proposed and adopted 
in the United States since the ACA was enacted, including the Budget Control Act of 2011, which includes provisions to reduce the 
federal deficit. The Budget Control Act, as amended, resulted in the imposition of 2% reductions in Medicare payments to providers, 
which began in April 2013 and will remain in effect through 2031 unless additional Congressional action is taken. In 2021, President 
Biden signed the American Rescue Plan Act of 2021 into law, which eliminated the statutory Medicaid drug rebate cap, previously set 
at 100% of a drug’s average manufacturer price, for single source and innovator multiple source drugs, beginning in 2024. These laws 
and regulations may result in additional reductions in Medicare and other healthcare funding and otherwise affect the prices we may 
obtain for any of our product candidates for which we may obtain regulatory approval or the frequency with which any such product 
candidate is prescribed or used. 
In August 2022, the Inflation Reduction Act of 2022 (IRA) was signed into law. The IRA includes several provisions that will impact 
our business to varying degrees, including provisions that create a $2,000 out-of-pocket cap for Medicare Part D beneficiaries, impose 
new manufacturer financial liability on all drugs in Medicare Part D, allow the U.S. government to negotiate Medicare Part B and Part 
D pricing for certain high-cost drugs and biologics without generic or biosimilar competition, require companies to pay rebates to 
Medicare for drug prices that increase faster than inflation and delay the rebate rule that would require pass through of pharmacy 
benefit manager rebates to beneficiaries. The effect of IRA on our business and the healthcare industry in general is not yet known. 
Further, there has been heightened governmental scrutiny over the manner in which manufacturers set prices for their marketed 
products, which have resulted in several Congressional inquiries and proposed bills designed to, among other things, bring more 
transparency to product pricing, review the relationship between pricing and manufacturer patient programs and reform government 
program reimbursement methodologies for products. In addition, the federal government, state legislatures, and foreign governments 
have shown significant interest in implementing cost containment programs, including price-controls and price transparency, 
restrictions on reimbursement, and requirements for substitution of generic products for branded prescription drugs to limit the growth 
of government paid health care costs. For example, the federal government has passed legislation requiring pharmaceutical 
Table of Contents
44

manufacturers to provide rebates and discounts to certain entities and governmental payors to participate in federal healthcare 
programs.  
Environment
We are subject to state and federal laws regarding environmental protection and hazardous substances, including the Occupational 
Safety and Health Act, the Resource Conservation and Recovery Act and the Toxic Substances Control Act. These and other laws 
govern the use, handling and disposal of various biologic, chemical and radioactive substances used in, and wastes generated by, 
operations. If our operations result in contamination of the environment, breach of our regulatory obligations or expose individuals to 
harm, we could be liable for damages and governmental fines. Equivalent laws have been adopted in foreign countries that impose 
similar obligations.

Item 1A. Risk Factors 
You should carefully consider the following risks and uncertainties, together with all other information in this Annual Report on Form 
10-K. Any of the risk factors we describe below could adversely affect our business, financial condition or results of operations and 
the market price of our common stock.
Risks related to commercialization and our products 
Uncertainty and evolving dynamics in the markets for COVID and RSV vaccines, and respiratory vaccines more generally, have in 
the past impacted and are likely to continue to impact our financial results.
There is significant uncertainty around the amount of future revenue we will recognize from sales of our COVID vaccine—which is 
our primary source of revenue—as well as sales of RSV and other respiratory vaccines. Accurately forecasting vaccination rates for 
our products, which directly impacts overall market size, has been difficult, and these difficulties may persist. Vaccination rates in the 
future may also be lower than our expectations, and are likely to be impacted by a number of factors, including public health authority 
recommendations, medical need, viral evolution and consumer motivation to vaccinate. Additionally, the recent Presidential election 
in the U.S. may impact policies and priorities related to our industry.  
In 2024, we recognized $3.1 billion of product sales, compared to $6.7 billion, $18.4 billion and $17.7 billion in 2023, 2022 and 2021, 
respectively. If demand for COVID vaccines continues to decline, we lose significant market share, or our products are subject to 
significant competitive pricing pressure, our product sales may not materialize consistent with our projections. Beyond COVID 
vaccines, in 2024, the overall RSV vaccine market was smaller than anticipated, in part due to recommendations from the CDC’s 
Advisory Committee on Immunization Practices (ACIP) regarding the frequency of vaccination and recommendations related to who, 
in terms of age or risk factors, should receive an RSV vaccine. These recommendations were more limited than anticipated and future 
advisory committee recommendations (including with respect to RSV re-vaccination and age group recommendations) may continue 
to negatively impact the size of the market. If we cannot effectively manage evolving market dynamics, our business, financial 
condition, results of operations and prospects may suffer.
We have experienced commercial challenges and are likely to experience additional challenges in the future.
We face risks and uncertainties related to successfully commercializing our products. For example, in 2024, we faced commercial 
challenges that led to lower-than-expected sales and required us to adapt our business strategy. We experienced difficulties 
maintaining our COVID vaccine market share and gaining market share in the U.S. for our RSV vaccine, where we were third to 
market. Moving forward, we may need to dedicate greater resources to our commercial efforts than we anticipate, and we may not 
realize a return on this investment. Additionally, we may be unsuccessful in accurately anticipating future rates of return for our 
products, which may adversely impact our accounting estimates.
Furthermore, we may seek to enter into agreements with others to utilize their marketing and distribution capabilities, but may be 
unable to enter into agreements on favorable terms, if at all. If we rely on others to commercialize our products, our revenues may be 
lower than if we commercialized these products ourselves. In addition, we may have little or no control over such third parties’ sales 
efforts. If our partners commit insufficient resources to commercialize our products, and we cannot independently develop necessary 
marketing capabilities, we may be unable to generate sufficient product revenue to sustain our business.
The vaccine market, and pharmaceutical market more generally, is intensely competitive, and we may not compete effectively in 
the market for existing or new products, treatment methods or technologies.
We compete with well-established, larger pharmaceutical companies for sales of our products, including against Pfizer and Sanofi for 
sales of our COVID vaccine and Pfizer and GSK for our RSV vaccine. These competitors (and others against whom we may compete 
now or in the future) have greater resources and experience than us across all stages of drug development and commercialization. For 
example, in 2024, our share of the COVID vaccine market declined due in part to increased commercial competition. Additionally, we 
faced continued exclusion from many European markets by a pandemic-era competitor contract with the European Commission. For 
RSV vaccines, we entered a market already occupied by two larger competitors and may continue to face difficulties achieving market 
share. These competitors have exploited and may in the future exploit their greater size, infrastructure, resources and experience to 
gain advantages in contracting with customers by, among other things, bundling their products, leveraging larger supply chains and 
greater purchasing power and utilizing their global networks.
In addition, certain U.S. private vaccine market practices, including regarding discounts, rebates and returns, may cause us to realize 
significantly lower revenues than list prices. We may also be adversely affected by similar market practices outside of the United 
Table of Contents
46

States. In some instances, our competitors have been able to offer more attractive terms than we can, and they may continue to do so in 
the future.
More generally, the pharmaceutical market is intensely competitive and evolving. Other companies, academic institutions, 
governmental agencies and public and private research organizations are developing products that may compete with programs in our 
development pipeline. These competitors may have products that have already been approved and accepted by the medical community 
or are in later stages of development. For example, we are developing a seasonal flu vaccine, for which there is a well-developed 
market, and we may be unsuccessful in developing a product or achieving market share. We may need to offer more favorable terms to 
gain market share (which we may be unable to do), which may negatively impact our profitability. Additionally, competitive products 
may make any products we develop obsolete or noncompetitive before we can recover the expenses of developing and 
commercializing our products.
Additionally, any products that we develop may struggle to compete against those of our competitors for a variety of reasons, 
including relative safety and effectiveness, degree of any side effects, shelf-life, ease of administration and the extent to which patients 
accept relatively new routes of administration, the timing and scope of regulatory approvals, the availability and cost of 
manufacturing, distribution, marketing and sales capabilities, price, reimbursement coverage and patent protection. Even if our 
products demonstrate superiority to those of competitors, consumers, retailers and the public may fail to appreciate that benefit, or 
existing purchase commitments for a competitor’s product may discourage them from purchasing from us. These factors, or the 
perception of these factors, could lead to a competitor’s product being more successfully commercialized. Further, the mRNA 
medicines field is growing rapidly, with increased competitive pressure from large and more established pharmaceutical companies. 
The actual or perceived success or failure of others may adversely impact our ability to commercialize our products. 
We may be unsuccessful in executing our cost efficiency and portfolio prioritization efforts.
Our broad clinical success and recent commercial challenges have necessitated a more selective and paced approach to our research 
and development investment. If we do not successfully implement our cost efficiency and prioritization programs, we may fail to meet 
our cash breakeven goals. Furthermore, as we pursue and fund the development of our prioritized programs, we may forego or delay 
pursuit of other opportunities that could later prove to have greater commercial potential. If our prioritized programs are unsuccessful, 
or not as successful as other programs could have been, we may be unable to realize a sustainable return on our investments and or 
achieve long-term growth. 
We have in the past, and may in the future, seek to resize our manufacturing infrastructure to reflect anticipated demand for our 
products. This resizing may result in our incurring costs associated with exiting commitments, such as with suppliers for raw materials 
and contract manufacturing organizations (CMOs). Additionally, as a result of lower demand for our products, we have experienced, 
and may in the future experience, increased costs with respect to raw material suppliers as we seek to exit or modify our purchase 
commitments. Further, we have entered, and may in the future enter, into non-cancellable or take-or-pay purchase commitments for 
raw materials that require a long lead time to procure, increasing our commitment exposure. 
We may be unsuccessful or delayed in updating our COVID vaccine to protect against future variants of the SARS-CoV-2 virus.
New SARS-CoV-2 strains may be more transmissible or cause more severe disease than earlier strains. Our COVID vaccines could be 
ineffective, or less effective than desired, in protecting against these new variants. Additionally, our decisions regarding vaccine 
development will be informed by guidance from the FDA and foreign regulators, which may impact the timing of development for our 
COVID vaccines. Different regulators have in the past and may in the future issue varying guidance regarding vaccine composition or 
populations who should receive a vaccine. If our efforts to develop variant-specific vaccines are not as successful as our competitors’, 
we could suffer reputational harm, loss of market share and adverse financial results. Additionally, we may expend significant 
resources adapting our vaccines or conducting clinical trials to protect against variants, but a market for our adapted vaccines may fail 
to develop or demand may not align with our projections or cost expenditures.
The commercial success of our products depends on the degree of market acceptance by physicians, patients, third-party payors 
and others in the medical community.
The degree of market acceptance of our products will depend on numerous factors, including:
•
efficacy and potential advantages over alternative treatments;
•
the duration of protection provided by our products compared to those of our competitors;
•
acceptance of mRNA products generally and the availability of competing non-mRNA medicines that may be preferred by 
the medical community or the public;
•
safety and the prevalence and severity of any side effects, including any limitations, restrictions (including for use together 
with other medicines) or warnings contained in a product’s approved labeling;
47

•
the prevalence and severity of any side effects resulting from checkpoint inhibitors or other products or therapies with which 
our products are co-administered;
•
relative convenience and ease of administration;
•
the willingness of the target patient population to try, and physicians to prescribe, new therapies;
•
the strength of marketing and distribution support and timing of market introduction of competitive products;
•
whether our product presentation meets customer demand (e.g., for single-dose presentations, or combination vaccines);
•
publicity and health authority communications concerning our products or competing products and treatments; and 
•
product cost and sufficient third-party insurance coverage or reimbursement, and patients’ willingness to pay out-of-pocket in 
the absence of third-party coverage or adequate reimbursement.
Even if a potential product displays a favorable efficacy and safety profile in clinical trials, market acceptance will be unknown until 
after it is launched. Our efforts to educate the medical community and third-party payors on the benefits of our products may require 
significant resources and may never be successful.
Sales of pharmaceutical products depend on the availability and extent of reimbursement from third-party payors, and we may be 
adversely impacted by changes to such reimbursement policies or rules.
Sales of pharmaceutical products in general depends to a significant extent on adequate coverage, pricing and reimbursement from 
third-party payors. When a new product is approved, the availability and extent of government and private reimbursement, and the 
pricing, for that product may be uncertain. Additionally, pricing and reimbursement for any product we develop may be adversely 
affected by various factors, including:
•
changes in, and implementation of, federal, state or foreign government regulations or private third-party payors’ 
reimbursement policies;
•
pressure by employers on private health insurance plans to reduce costs; and
•
consolidation and increasing assertiveness of payors seeking price discounts or rebates in connection with the placement of 
our products on their formularies and, in some cases, the imposition of restrictions on access or coverage of particular drugs 
or pricing determined based on perceived value.
Our ability to set the price for any product we develop will vary significantly by country. Our inability to obtain and maintain adequate 
prices in a particular country may limit the revenues from our products within that country and adversely affect our ability to secure 
acceptable prices in existing and potential new markets, which may limit market growth. This may create the opportunity for third-
party cross-border trade or influence our decision whether to sell a product, thus adversely affecting our geographic expansion plans 
and revenues.
Many payors continue to adopt benefit plan changes that shift a greater portion of prescription costs to patients, including more limited 
benefit plan designs, higher patient co-pay or co-insurance obligations and limitations on patients’ use of commercial manufacturer co-
pay payment assistance programs. Significant consolidation in the health insurance industry has resulted in a few large insurers and 
pharmacy benefit managers exerting greater pressure in pricing and usage negotiations with drug manufacturers, significantly 
increasing discounts and rebates required of manufacturers and limiting patient access and usage. Further consolidation among 
insurers, pharmacy benefit managers and other payors would increase the negotiating leverage such entities have over us and other 
drug manufacturers. Additional discounts, rebates, coverage or plan changes, restrictions or exclusions as described above could have 
a material adverse effect on sales of our affected products, particularly our therapeutic products or those that are individualized for a 
particular patient. Coverage and reimbursement by a third-party payor may depend on various factors, including the third-party 
payor’s determination that use of a product is a covered benefit under its health plan, safe, effective and medically necessary, 
appropriate for the specific patient, cost-effective and neither experimental nor investigational.
Additionally, target patient populations for some of our product candidates may be small (e.g., for rare genetic diseases) or require 
individual customization (e.g., for our INTs). The pricing and reimbursement of our medicines, if approved, must be adequate to 
support commercial infrastructure. If we cannot obtain adequate levels of reimbursement, we may be unable to successfully market 
and sell our products. The manner and level at which reimbursement is provided for services related to our products (e.g., for 
administration to patients) is also important. Inadequate reimbursement for such services may discourage physicians from prescribing 
or recommending our products, adversely affecting our ability to market or sell those products.
The market opportunities for our products and product candidates may be smaller than we believe, or we may be unable to 
successfully identify clinical trial participants.
We focus certain of our research and product development activities on treatments for severe rare genetic diseases, where the patient 
populations are difficult to ascertain or small. Additionally, our products may only be approved for certain populations or lines of 
treatment.
48

Our estimates of addressable patient populations are based on our beliefs, and have been derived from a variety of sources, including 
scientific literature, surveys of clinics, patient foundations or market research, and may prove to be incorrect. Further, new studies may 
change the estimated incidence or prevalence of these diseases. The number of trial participants may be lower than expected and 
potential clinical trial participants or patients may not be otherwise amenable to treatment with our product candidates or products, or 
new clinical trial participants or patients may become increasingly difficult to identify or gain access to. Even if we obtain significant 
market share for our products, if approved, because the potential target populations are small, these medicines may never be profitable. 
Furthermore, the size of markets that we target may be impacted by health authority recommendations regarding who should receive 
our products, which may be impacted by the new U.S. federal government administration.
Risks related to our pipeline, product development and regulatory review
If we cannot obtain, or are delayed in obtaining, regulatory approvals and advisory committee recommendations, we will be unable 
to effectively commercialize, or will be delayed in commercializing, our product candidates.
Any products we may develop are subject to comprehensive regulation by the FDA and comparable foreign regulators. To obtain 
required regulatory approvals to commercialize any product candidate, we must demonstrate through extensive preclinical studies and 
clinical trials that our products are safe and effective for their intended use. In addition, regulators conduct pre-approval inspections 
and negative findings may lead to delay in approval and failure to commercialize a product candidate. Even once approved, products 
may be subject to recommendations from advisory committees, such as the ACIP, before or after they can be brought to market.  
To date, we have only received regulatory approvals for our COVID and RSV vaccines, and our current or future product candidates 
may never obtain regulatory approval or advisory committee recommendations. We may need to rely on third parties to assist us in 
making applications for marketing approvals. Preclinical studies and clinical trials conducted in one country may not be accepted by 
regulators elsewhere, and regulatory approval in one country does not guarantee approval in another. Regulators may require that we 
conduct additional clinical trials to support our applications for approval beyond our clinical development plans, which may result in 
increased expense and delays in bringing our products to market.   
Additionally, the process of obtaining marketing approvals is expensive, time-consuming and uncertain, and can vary substantially 
based on many factors, including the type, complexity and novelty of the product candidates involved. Changes in marketing approval 
policies during the development period, changes in law or changes in regulatory review may delay the review of a submitted product 
application. The FDA and foreign regulators have substantial discretion in the approval process and may refuse to accept any 
marketing approval application or may decide that our data are insufficient for marketing approval and require additional preclinical, 
clinical or other studies. In addition, varying interpretations of the data obtained from preclinical and clinical testing could delay, limit 
or prevent marketing approval of a product candidate. Additional delays or non-approval may result if an FDA advisory committee or 
other regulator recommends non-approval or restrictions on approval. 
Clinical development is lengthy and uncertain, and our clinical programs may be delayed or terminated, or may be more costly to 
conduct than we anticipate.
Clinical testing is expensive, complex and lengthy, and its outcome is inherently uncertain. Most product candidates that commence 
clinical trials are never approved as products. Although we have demonstrated historical success with our platform technology, we 
may not continue to realize the same levels of success with clinical trials in the future. We and our strategic collaborators also may 
experience unforeseen events during, or as a result of, any clinical trials that we or they conduct that could delay or prevent us or them 
from successfully developing our product candidates and gaining approval from regulators. Events that might prevent us from 
proceeding with clinical trials could include:
•
regulators, Institutional Review Boards (IRBs) or ethics committees may not authorize us or our investigators to commence a 
clinical trial or conduct a clinical trial at a prospective trial site;
•
we may experience delays in reaching, or fail to reach, agreement on favorable terms with prospective trial sites and 
prospective contract research organizations (CROs);
•
changes to the scale or site of our manufacturing could cause significant delays or changes in our clinical trial designs;
•
the outcome of our preclinical studies and our early clinical trials may not be predictive of the success of later clinical trials, 
and interim results of a clinical trial do not necessarily predict final results;
•
we may be unable to establish or achieve clinically meaningful endpoints for our studies;
•
if we make changes to our product candidates after clinical trials have commenced (which we have done in the past), we may 
be required to repeat earlier stages or delay later stages of clinical testing;
•
clinical trials of any product candidates may fail to show safety or efficacy, or may produce negative or inconclusive results, 
and we may decide, or regulators may require us, to conduct additional nonclinical studies or clinical trials, or we may decide 
to abandon product development programs;
49

•
our product candidates, or other medicines in the same class as ours, may cause significant adverse events or other 
undesirable side effects, such as the immunogenicity of the LNPs or their components, the immunogenicity of the protein 
made by the mRNA or degradation products, any of which could lead to serious adverse events, or other effects;
•
our third-party contractors may fail to comply with regulatory requirements or meet their contractual obligations to us in a 
timely manner, or at all, or may deviate from the applicable clinical trial protocol or withdraw from the applicable clinical 
trial, which may require that we add new clinical trial sites;
•
regulators may impose a complete or partial clinical hold on a clinical trial (or a trial of another company working on mRNA 
medicines), or we or our investigators, IRBs or ethics committees may suspend or terminate clinical research or trials for 
various reasons, including quality events, noncompliance with regulatory requirements or a finding that participants are being 
exposed to an unacceptable benefit-risk ratio;
•
the supply or quality of our product candidates or other materials necessary to conduct clinical trials may be insufficient or 
inadequate;
•
safety and efficacy concerns regarding our product candidates will be considered by us and by the FDA and other regulators 
as we pursue clinical trials of new product candidates, develop effective informed consent documentation and work with 
IRBs and scientific review committees (SRCs);
•
safety or efficacy concerns could arise from nonclinical or clinical testing of other therapies targeting a similar disease state 
or other therapies, such as gene therapy, that are perceived as similar to ours;
•
adverse side effects could be observed in future clinical trials where our product candidates are administered in combination 
with other therapies (such as the co-administration of our INT product candidate, mRNA-4157);
•
delays in developing assays acceptable to the FDA or other regulators; and
•
a lack of adequate funding to continue a particular clinical trial, including due to higher-than-anticipated costs.
Additionally, we have conducted and may conduct in the future “open-label” clinical trials, where both the patient and investigator 
know whether the patient is receiving the investigational product candidate, an approved drug or a placebo. The results from an open-
label clinical trial may not be predictive of future clinical trial results from a controlled environment with a placebo or active control. 
Further, the FDA or other regulators may change the requirements for approval even after they have reviewed and commented on the 
design for our clinical trials. Significant preclinical or nonclinical testing and studies or clinical trial delays for our product candidates 
could allow our competitors to bring products to market before we do and could harm our business.
There are risks unique to each of our programs and modalities and risks applicable across programs and modalities, which may 
delay or prevent our ability to advance one or more of our programs in clinical development, obtain regulatory approval or 
commercialize our products.
Certain features in our product candidates, including those related to mRNA, chemical modifications, surface chemistries, LNPs and 
their components, may result in risks that apply to some or all of our programs and modalities. As our product candidates progress, we 
or others may determine that certain of our risk allocation decisions were incorrect or insufficient, we made platform-level technology 
mistakes, individual programs or our mRNA science in general has technology or biology risks that were unknown or under-
appreciated, our choices on how to develop our infrastructure to support our scale will result in an inability to manufacture our product 
candidates for clinical trials or otherwise impair our manufacturing or we have allocated resources in such a way that we cannot 
recover large investments or rapidly re-direct capital.
We utilize earlier programs in a modality to understand the technology risks within the modality, including the program’s 
manufacturing and pharmaceutical properties. Even if our earlier programs in a modality are successful in any phase of development, 
other programs may fail at that stage, and any program may fail at a later phase of development. This may be a result of technical 
challenges or biology risk unique to that program. The biology risk across much of our pipeline represents targets and pathways not 
clinically validated by one or more approved drugs, and the risk that the targets or pathways that we have selected may not be effective 
will continue to apply across our current and future programs.
As we progress our programs through clinical development, new technical challenges may arise that cause an entire modality to fail. 
Additionally, any portfolio-spanning risks, whether known or unknown, such as an increased risk of a particular type of side effect, if 
realized in any one of our programs, would have a material and adverse effect on our other programs and on our overall business.
There are also specific additional risks to certain of our modalities and programs. For example, prophylactic vaccines typically require 
clinical testing in up to tens of thousands of healthy volunteers to define an approvable benefit-risk profile. The need to show a high 
degree of safety and tolerability when dosing healthy individuals could result in rare and even spurious safety findings, negatively 
impacting a program prior to or after commercial launch. Even if we observe positive safety, tolerability and levels of immunogenicity 
in early clinical trials, we may not observe acceptable safety or efficacy profiles in later-stage trials required for approval of these 
programs.
50

There are many clinical and manufacturing challenges specific to our INT product candidates and any other neoantigen cancer 
vaccines we may develop. These risks include a rapid production turn-around time measured in weeks in order to supply patients in 
our clinical trials before further progression and mutation of their tumors, the significant costs incurred in making individualized 
medicines and potential lack of immune responses due to the biology of the tumor or immune status of the patient. These risks apply to 
our INT product candidates and other neoepitope investigational medicine programs. 
Additionally, there may be challenges in delivering an adequate quantity of active pharmaceutical ingredient (API) required to drive 
efficacy due to the limitation in volume of API that can be delivered to a specific location, like a tumor or injured tissue. Our 
investigational therapies for local injections often require specialized skills for conducting a clinical trial that could delay clinical trials 
or slow or impair commercialization of a product due to the poor adoption of injected local therapeutics. In addition, the uncertain 
translatability of target selection from preclinical animal models, including mouse and non-human primate models, to successful 
clinical trial results may be impossible, particularly for systemic therapies and cancer vaccines. In general, several biological steps are 
required for delivery of mRNA to translate into therapeutically active medicines. These processing steps may differ between 
individuals or tissues, potentially leading to variable levels of therapeutic protein, variable activity, immunogenicity or variable 
distribution to tissues for a therapeutic effect. Gene therapies and mRNA medicines may activate one or more immune responses 
against any and all components of the drug product (e.g., the mRNA or the delivery vehicle, such as an LNP) as well as against the 
encoded protein, giving rise to potential immune reaction related adverse events. Eliciting an immune response against the encoded 
protein may impede our ability to achieve a pharmacologic effect upon repeat administration or a side effect.
We may experience delays in enrolling participants in our clinical trials.
Enrolling participants in our clinical trials is critical to our success. Difficulties or delays in enrolling a sufficient number of clinical 
trial participants may result in increased costs or affect the timing or outcome of our planned clinical trials, which could prevent trial 
completion and adversely affect our ability to advance the development of and obtain regulatory approval for our product candidates. 
Participant enrollment is affected by many factors, including:
•
severity of the disease under investigation;
•
complexity and design of the clinical trial protocol;
•
size of the patient population;
•
eligibility criteria for the clinical trial in question, including age-based eligibility criteria limiting subject enrollment to 
adolescent or pediatric populations;
•
proximity and availability of clinical trial sites for prospective trial participants;
•
availability of competing therapies and clinical trials;
•
patient referral practices of physicians;
•
ability to monitor trial participants adequately during and after treatment;
•
ability to recruit qualified clinical trial investigators;
•
clinicians’ and trial participants’ perceptions as to the potential advantages and side effects of the product candidate being 
studied in relation to other available therapies, including any new drugs or treatments that may be approved for the 
indications we are investigating;
•
adverse results or other adverse safety signals in our trials or related to other product candidates, and the resulting negative 
publicity, could discourage potential clinical trial participants and their doctors from participating in our trials; and
•
our ability to obtain and maintain participant informed consent.
Additionally, we may have limited or no ability to influence enrollment in clinical trials where our collaborators control clinical 
development. Even if we or our strategic collaborators can enroll clinical trial participants, there is no guarantee that such participants 
will ultimately be dosed as part of, or complete, a clinical trial.
mRNA drug development has substantial clinical development and regulatory risks due to the novel nature of this new class of 
medicines, and the negative perception of the efficacy, safety or tolerability profile of any product candidates that we or others 
develop could adversely affect our ability to conduct our business, advance our product candidates or obtain regulatory approvals.
Very few mRNA medicines have been authorized or approved to date by the FDA or other regulators, and efficacy, safety and 
immunogenicity data and real-world evidence with respect to mRNA medicines continue to accumulate. We may observe new, more 
frequent or more severe adverse events in subjects participating in ongoing clinical trials or among individuals vaccinated with mRNA 
vaccines. For example, some studies have suggested that our COVID vaccine may be associated with higher rates of myocarditis and 
pericarditis in young males compared to other COVID vaccines. If similar observations are made in recipients of our other products or 
product candidates, or if other unexpected safety issues arise, we could suffer significant damage to our reputation and that of our 
mRNA platform. Such events could lead to other issues, including delays in our other programs, the need to re-design our clinical 
trials and the need for significant additional financial resources. In addition, the FDA and other regulators may interpret data from our 
51

clinical trials differently than we do and such agencies may require us to conduct additional studies or analyses, which could delay or 
prevent us from obtaining full regulatory approvals in certain jurisdictions or for certain demographics. For example, in October 2021, 
the FDA requested that we explore a lower dosage for our COVID vaccine in adolescents, which extended the length of clinical trials 
in this population prior to receiving regulatory authorization. In addition, local legislatures may attempt to regulate or restrict the use 
of mRNA medicines in their jurisdictions.
Successful discovery and development of mRNA medicines by us or our strategic collaborators is highly uncertain and depends on 
many factors beyond our or their control. We constantly make business decisions and take calculated risks to advance our 
development efforts and pipeline, including those related to mRNA technology, delivery technology and manufacturing processes, 
which ultimately may be unsuccessful.
Our product candidates that appear promising in the early phases of development may fail to advance, experience delays in the clinic, 
experience clinical holds or fail to reach the market for many reasons, including:
•
nonclinical or preclinical study, or clinical trial, results may show potential mRNA medicines to be less effective than desired 
or to have harmful or problematic side effects or toxicities;
•
adverse results in our clinical trials, or in those of others developing similar products, or adverse effects relating to mRNA, or 
our LNPs, may lead to negative publicity or delays in or termination of our programs;
•
the efficacy or safety of a combination vaccine product candidate could be less than that seen with the administration of the 
vaccines separately, which could prevent the combination product from obtaining regulatory approval;
•
adverse events related to products that are perceived to be similar to mRNA medicines, such as those related to gene therapy 
or gene editing, could result in a decrease in the perceived benefit of one or more of our programs, increased regulatory 
scrutiny, decreased confidence by patients and clinical trial collaborators in our product candidates and less demand for any 
product that we may develop;
•
the insufficient ability of our translational models to reduce risk or predict outcomes in humans, particularly given that each 
component of our product candidates may have a dependent or independent effect on safety, tolerability and efficacy, which 
may be species-dependent;
•
manufacturing failures or insufficient supply of current Good Manufacturing Practice (cGMP) materials for clinical trials, or 
higher than expected cost could delay or set back clinical trials, or make mRNA medicines commercially unattractive;
•
changes that we make to optimize our manufacturing, testing or formulating of cGMP materials could impact the safety, 
tolerability and efficacy profile of our product candidates;
•
pricing or reimbursement issues or other factors that delay clinical trials or make any mRNA medicine uneconomical or 
noncompetitive with other therapies;
•
our large pipeline of product candidates could result in a greater quantity of reportable adverse events, including suspected 
unexpected serious adverse reactions, other reportable negative clinical outcomes, manufacturing reportable events or 
material clinical events that could lead to clinical delay or hold by the FDA or applicable regulatory authority or other clinical 
delays, any of which could negatively impact the perception of one or more of our programs, as well as our business as a 
whole;
•
failure to timely advance our programs or a failure or delay in receiving necessary regulatory approvals due to, among other 
factors, slow or failure to complete enrollment in clinical trials, withdrawal by trial participants from trials, failure to achieve 
trial endpoints, additional time requirements for data analysis, data integrity issues, preparation of a BLA or the equivalent 
application, discussions with the FDA or EMA, a regulatory request for additional nonclinical or clinical data or safety 
formulation or manufacturing issues may lead to our inability to obtain sufficient funding;
•
new legislation or regulations passed by U.S., state or foreign governments in response to negative public perception of 
mRNA medicines; and
•
the proprietary rights of others and their competing products and technologies that may prevent our mRNA medicines from 
being commercialized.
Because we are developing some of our product candidates for the treatment of diseases in which there is little clinical experience 
and, in some cases, using new endpoints or methodologies, the FDA or other regulators may not consider the endpoints of our 
clinical trials to provide clinically meaningful results.
There are no pharmacologic therapies approved to treat the underlying causes of many diseases that we are currently attempting to 
address or may address in the future. For instance, for many of the rare diseases for which we are developing treatments, few clinical 
trials have been attempted, and there are no approved drugs to treat these diseases. As a result, the design and conduct of clinical trials 
of product candidates for the treatment of these disorders may take longer, be more costly or be less effective due to the novelty of 
development in these diseases.
Even if the FDA does find our success criteria to be sufficiently validated and clinically meaningful, we may not achieve the pre-
specified endpoint to a degree of statistical significance in our pivotal or other clinical trials. Further, even if we achieve the pre-
52

specified criteria, our clinical trials may produce unpredictable or inconsistent results compared against the more traditional efficacy 
endpoints in the trial. The FDA could give overriding weight to other efficacy endpoints over a primary endpoint, even if we achieve 
statistically significant results on that endpoint, if we do not do so on our secondary efficacy endpoints. The FDA also weighs the 
benefits of a product against its risks and may view the efficacy results in the context of safety as not being supportive of licensure. 
Regulators in other countries may make similar findings with respect to these endpoints.
Certain mRNA therapies are classified as gene therapies by the FDA and the EMA. The association of our products with gene 
therapies could result in increased regulatory burdens, impair the reputation of our products or negatively impact our platform or 
our business.
There are only a few approved gene therapy products in the United States or foreign jurisdictions, and there have been well-reported 
significant adverse events associated with their testing and use. Regulatory requirements governing gene therapy products have 
evolved and may continue to change in the future, and the implications for mRNA therapies are unknown. For example, the FDA has 
established an office, now called the Office of Therapeutics Products (OTP), within its Center for Biologics Evaluation and Research 
(CBER) to consolidate the review of gene therapy and related products, and convenes the Cellular, Tissue and Gene Therapies 
Advisory Committee to advise CBER on its review. In the EU, certain mRNA therapies have been characterized as gene therapy 
medicinal products, which falls within a broader category known as Advanced Therapy Medicinal Products (ATMPs), which are 
subject to additional regulatory requirements. In certain countries, mRNA therapies have not yet been classified or any such 
classification is not known to us; for example, in Japan, the Pharmaceuticals and Medical Devices Agency has not taken a position on 
the regulatory classification of mRNA therapies. Notwithstanding the differences between mRNA medicines and gene therapies, the 
classification of some of our mRNA product candidates as gene therapies in the U.S., the EU and potentially other countries could 
adversely impact our ability to develop our product candidates. For instance, a clinical hold on gene therapy products may apply to our 
mRNA product candidates irrespective of the differences between gene therapies and mRNA.
Adverse events reported with respect to gene therapies could adversely impact one or more of our programs. Although our mRNA 
product candidates are designed not to make any permanent changes to cell DNA, regulatory agencies or others could believe that 
adverse effects of gene therapies caused by introducing new DNA and irreversibly changing the DNA in a cell could also be a risk for 
our mRNA investigational therapies, and as a result may delay one or more of our clinical trials or impose additional testing for long-
term side effects. Any new requirements and guidelines promulgated by regulatory agencies may negatively affect our business by 
lengthening the regulatory review process, requiring us to perform additional or larger studies or increasing our development costs, 
any of which could lead to changes in regulatory positions and interpretations, delay or prevent advancement or approval and 
commercialization of our product candidates, or lead to significant post-approval studies, limitations or restrictions. As we advance 
our product candidates, we will be required to consult with these regulatory agencies and advisory committees and comply with 
applicable requirements and guidelines. If we fail to do so, we may be required to delay or discontinue development of some or all of 
our product candidates.
Our work in genomic editing is subject to all risks associated with gene therapies. Genome editing technologies are relatively new and 
their therapeutic utility is largely unproven. Public perception and related media coverage of potential therapy-related efficacy or 
safety issues, as well as ethical concerns related specifically to genome editing, may adversely influence the willingness of subjects to 
participate in clinical trials. In addition, any review conducted by an institutional biosafety committee may result in delay or prevent 
initiation of a gene therapy clinical trial.
Additionally, if any such therapeutic is approved, physicians and patients may be slow or fail to accept these novel and personalized 
treatments. Physicians, health care providers and third-party payors often are slow to adopt new products, technologies and treatment 
practices, particularly those that may also require additional upfront costs and training. Physicians may not be willing to undergo 
training to adopt these novel and potentially personalized therapies, may decide the particular therapy is too complex or potentially 
risky to adopt without appropriate training and may choose not to administer the therapy. Further, due to health conditions, genetic 
profile or other reasons, certain patients may not be candidates for the therapies. In addition, responses by federal and state agencies, 
congressional committees and foreign governments to negative public perception, ethical concerns or financial considerations may 
result in new legislation, regulations or medical standards that could limit our ability to develop or commercialize any product 
candidates, obtain or maintain regulatory approval or otherwise achieve profitability. Based on these and other factors, health care 
providers and payors may decide that the benefits of these new therapies do not or will not outweigh their costs.
Our products are, and any future products will be, subject to regulatory scrutiny.
Even if we obtain regulatory approval in a jurisdiction, we may remain subject to significant restrictions on the indicated uses or 
marketing of our product and ongoing requirements for potentially costly post-approval studies-such as those required under an 
accelerated approval by the FDA or other similar type of approval-or post-market surveillance. For example, the holder of an approved 
BLA must monitor and report adverse events and monitor and report any failure of a product to meet the specifications in the BLA, as 
well as submit new or supplemental applications and obtain FDA approval for certain changes to the approved product, product 
53

labeling, or manufacturing process. Additionally, pharmacovigilance obligations under the regulatory regimes of the jurisdictions 
where our products are distributed require us to collect, process, analyze and monitor safety data and to identify and evaluate adverse 
reactions to our products as they are administered in those jurisdictions. If we or any of our partners assisting us in meeting these 
obligations cannot comply with relevant regulations, we may be subject to sanctions, increased costs and reputational harm, or our 
regulatory authorizations to distribute our vaccines in the relevant jurisdiction may be revoked or curtailed.
Furthermore, advertising and promotional materials must comply with FDA rules and regulations and are subject to FDA review, in 
addition to other potentially applicable federal and state laws. In addition, regulatory agencies may not approve the labeling claims 
that are necessary or desirable for the successful commercialization of our product candidates.
We are required by the FDA to conduct post-marketing studies for our COVID vaccine (mRNA-1273), including to assess the risk of 
myocarditis and pericarditis and to evaluate outcomes in pregnant women and infants post-vaccination. We or others could identify 
previously unknown side effects, or known side effects could be observed as being more frequent or severe than in clinical trials or 
earlier post-marketing periods. If we, our contract manufacturers or other strategic collaborators fail to comply with applicable post-
approval regulatory requirements, a regulator may issue a warning letter asserting that we are in violation of the law, seek an 
injunction or impose civil or criminal penalties or monetary fines, suspend or withdraw regulatory approval or revoke a license, 
suspend any ongoing clinical trials, refuse to approve a pending BLA or supplements to a BLA submitted by us, seize or recall 
products or product candidates, or require field alerts to physicians, pharmacists and hospitals or refuse to allow us to enter into supply 
contracts. We could also be required to conduct additional nonclinical studies or clinical trials, or implement changes in labeling or to 
our manufacturing processes, specifications or facilities. Initiation of any government investigation or lawsuit, including class-action 
lawsuits, would require us to expend significant time and resources in response and would likely generate negative publicity. The 
occurrence of any event or penalty described above may inhibit our ability to commercialize our COVID vaccine, or any future 
approved products, and generate revenues. Our COVID vaccine is still subject to an emergency use authorization (EUA) for pediatric 
populations, and this EUA could be revoked for a variety of reasons, including if the FDA determines that the underlying health 
emergency no longer exists or warrants such authorization.  
Additionally, the FDA or other foreign regulators could require us to adopt Risk Evaluation and Mitigation Strategies (REMS) for any 
product to ensure that the benefits of treatment outweigh the risks for each potential patient, which may include, among other things, a 
medication guide outlining the risks of the product for distribution to patients, a communication plan to health care practitioners, 
extensive patient monitoring or distribution systems and processes that are highly controlled, restrictive and more costly than what is 
typical for the industry. Furthermore, if we or others later identify undesirable side effects caused by any product that we develop, 
several potentially significant negative consequences could result, including the suspension or withdrawal of approvals and licenses, 
the addition of warning labels, changes to the way a product is administered, the requirement to conduct further clinical trials, lawsuits 
or increased liability for harm to patients and their children and reputational harm to us. Any of these events could prevent us from 
achieving or maintaining market acceptance of any products we develop.
Additionally, the U.S. Supreme Court’s June 2024 decision in Loper Bright Enterprises v. Raimondo overturned the longstanding 
Chevron doctrine, under which courts were required to give deference to regulatory agencies’ reasonable interpretations of ambiguous 
federal statutes. The Loper decision could result in additional legal challenges to regulations and guidance issued by federal agencies, 
including the FDA, on which we rely. Additionally, the Loper decision may result in increased regulatory uncertainty, inconsistent 
judicial interpretations and other impacts to the agency rule-making process. We cannot predict the likelihood, nature or extent of 
government regulation that may arise from future legislation or administrative action or as a result of legal challenges, either in the 
United States or abroad. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or 
policies, or if we are not able to maintain regulatory compliance, our business could be materially harmed.
Preclinical development is lengthy and uncertain, especially for mRNA medicines.
Much of our pipeline is in preclinical development, and these programs could be delayed or not advanced into the clinic. Before we 
can initiate clinical trials for a product candidate, we must complete extensive preclinical studies, including IND-enabling good 
laboratory practice (GLP) toxicology testing. We must also complete extensive work on Chemistry, Manufacturing, and Controls 
(CMC) activities to be included in an IND submission. CMC activities for mRNA medicines require extensive manufacturing 
processes and analytical development, which is uncertain and lengthy. We have had and may in the future have difficulty identifying 
appropriate buffers and storage conditions to enable sufficient shelf life of batches of our product candidates. If we must produce new 
batches, our preclinical studies could be delayed. We cannot be certain of the timely completion of our preclinical testing and studies, 
whether the FDA or other regulators will accept the results or if the outcome of our preclinical testing, studies and CMC activities will 
ultimately support further development of our programs. As a result, we may be unable to submit INDs or similar applications for our 
preclinical programs on the timelines we expect, if at all, and such applications may not result in the FDA or other regulators allowing 
clinical trials to begin.

Risks related to the manufacturing of our commercial products and product candidates
We or our third-party manufacturers may encounter difficulties in manufacturing, product release, shelf life, testing, storage, 
supply chain management or shipping for any of our products.
The manufacturing processes for our mRNA medicines are novel and complex. We and our collaborators have experienced and may 
continue to encounter difficulties in manufacturing, product release, shelf life, testing, storage, supply chain management or shipping, 
including delays as our supply chain expands and grows more complex. We may experience difficulties effectively managing and 
executing the complexities of a larger and multi-product supply plan, including those resulting from complexities of producing batches 
at larger scale, equipment failure, human error, choice and quality of raw materials and excipients, analytical testing technology and 
product instability. Further, mRNA medicines encapsulated in LNPs must be developed and manufactured under well-controlled 
conditions, or pharmacological activity can be adversely impacted.
In an effort to optimize product features, we have in the past and may in the future make changes to our product candidates in their 
manufacturing and stability formulation and conditions. This has in the past and may in the future result in our having to resupply 
batches for preclinical or clinical activities when there is insufficient product stability during storage and insufficient supply. 
Insufficient stability or shelf life of our product candidates could materially delay our ability to continue clinical trials or require us to 
begin a new clinical trial with a newly formulated drug product, due to the need to manufacture additional preclinical or clinical 
supply.
Our high rate of innovation causes a high degree of technology change that can negatively impact product comparability during and 
after clinical development. Furthermore, technology changes may drive the need for changes in, modification to, or the sourcing of 
new manufacturing infrastructure or may adversely affect third-party relationships.
In many cases, we may need to utilize multiple batches of drug substance and drug product to meet the supply requirement of a single 
preclinical study or clinical trial. Failure in our ability to scale up batch size or failure in any batch, which we have experienced in the 
past, may lead to a substantial delay in our clinical trials or in the commercialization of any approved product. For example, the 
changes we make as we continue developing new manufacturing processes for our drug substance and drug product may impact 
specification and stability of the drug product, and may lead to failure of batches, resulting in a substantial delay in delivery of 
commercial product or conduct of our clinical trials. Our mRNA product candidates may prove to have a stability profile that leads to 
a lower than desired shelf life of the final approved medicine. This poses risk in supply requirements, wasted stock and higher cost of 
goods.
We are dependent on a number of equipment providers who are also implementing novel technology. Further, we have developed our 
own custom manufacturing equipment for certain of our medicines. If we encounter unexpected performance issues with such 
equipment, we could encounter delays or interruptions to clinical and commercial supply. Due to the number of different programs, we 
may have cross contamination of product candidates inside of our factories, CROs, suppliers or in the clinic that affect the integrity of 
our product candidates.
As we scale the manufacturing output for commercial production and particular programs, we plan to continuously improve yield, 
purity and the pharmaceutical properties of our products and product candidates from IND-enabling studies through commercial 
launch, including shelf-life stability, and solubility properties of drug product and drug substance. Because of continuous improvement 
in manufacturing processes, we may switch processes for a particular program during development. However, after a change in 
process, more time will be required for pharmaceutical property testing, such as 6 or 12 month stability testing. That may require 
resupplying clinical material or making additional cGMP batches to keep up with clinical trial demand before such pharmaceutical 
property testing is completed.
We utilize a number of raw materials and excipients that have a single source of supply, are new to the pharmaceutical industry and 
are being employed in a novel manner. Some of these raw materials and excipients have not been scaled to a level to support 
commercial supply and could experience unexpected manufacturing or testing failures or supply shortages. Such issues with raw 
materials and excipients could cause delays or interruptions to clinical and commercial supply of our products or product candidates.
We have established several analytical assays and may have to establish several more to assess the quality of our mRNA product 
candidates. We may identify gaps in our analytical testing strategy that might prevent release of product or could require product 
withdrawal or recall. For example, we may discover new impurities that have an impact on product safety, efficacy or stability. This 
may lead to an inability to release mRNA product candidates until the manufacturing or testing process is rectified.
55

As we grow as a commercial company and our drug development pipeline increases and matures, the increased demand for 
clinical and commercial supplies from our facilities and third parties may impact our ability to operate. We rely on third-party 
service providers, all of whom have inherent risks in their operations.
Completion of our trials and commercialization of our product candidates require access to, or development of, facilities to 
manufacture our vaccine candidates at sufficient yields and at commercial scale. We expect to continue to make significant 
investments in our manufacturing capacity and commercial network as we continue to expand our commercial launch efforts. We 
expect to bring manufacturing plants online in Australia, Canada and the United Kingdom in 2025 and are subject to risks associated 
with operationalizing these facilities, including with respect to plant licensures.
To supplement our internal manufacturing infrastructure, we have entered into agreements for the production, as well as for 
commercial fill-finish manufacturing, of our products to supply markets globally. We may need to engage additional third parties in 
the future to meet our capacity needs. If we cannot enter into such arrangements on favorable terms, or at all, our ability to develop, 
manufacture and distribute our products would be adversely affected. Further, efforts to establish these capabilities may not meet 
initial expectations as to scheduling, scale-up, reproducibility, yield, purity, cost, potency or quality. If we are unable to institute 
necessary controls related to product development, manufacturing and quality, we may encounter difficulties producing our products 
on the timelines and in the quantities set forth in our supply agreements or to meet potential future demand.
We currently utilize, and expect to continue to utilize, third parties to, among other things, manufacture raw materials, components, 
parts, and consumables and to perform quality testing. If the field of mRNA and other nucleic acid medicines continues to expand, we 
may encounter increasing competition for these materials and services. Demand for third-party manufacturing or testing facilities may 
grow at a faster rate than their existing capacity, which could disrupt our ability to find and retain third-party manufacturers capable of 
producing sufficient quantities of such raw materials, components, parts and consumables required to manufacture our mRNA product 
candidates. The use of service providers and suppliers could expose us to risks, including:
•
termination or non-renewal of supply and service agreements in a manner or at a time that is costly or damaging to us;
•
disruptions to the operations of these suppliers and service providers caused by conditions unrelated to our business or 
operations, including the bankruptcy of the supplier or service provider; and
•
inspections of third-party facilities by regulators that could have a negative outcome and result in delays to or termination of 
their ability to supply our requirements.
Our reliance on third-party manufacturers may adversely affect our operations or result in unforeseen delays or other problems beyond 
our control. Because of contractual restraints and the limited number of third-party manufacturers with the expertise, required 
regulatory approvals and facilities to manufacture our bulk vaccines on a commercial scale, replacement of a manufacturer may be 
expensive and time-consuming and may cause interruptions in the production of our vaccine. Regulators may also require us to 
register our facilities or those of another supplier if we terminate an existing third-party manufacturer relationship, which could lead to 
delays or our inability to supply a particular market. A third-party manufacturer may also encounter difficulties, delays or interruptions 
in production, including:
•
difficulties with production costs, scale up and yields;
•
availability of raw materials and supplies;
•
quality control and assurance;
•
shortages of qualified personnel;
•
compliance with strictly enforced regulations that vary in each country where products might be sold; and
•
lack of capital funding.
We are subject to operational risks associated with the physical and digital infrastructure at our manufacturing facilities and those 
of our external service providers.
Our manufacturing facilities incorporate a significant level of automation of equipment with integration of several digital systems, 
including those that may utilize artificial intelligence (AI), to improve efficiency of operations. The digitization of our facilities 
exposes us to the risk of process equipment malfunctions. These risks include potential system failures or shutdowns due to internal or 
external factors including design issues, system compatibility or potential cybersecurity compromises, incidents or breaches. Upgrades 
or changes to our systems, infrastructure or the software that we implement, use, or upon which our business relies, may result in the 
introduction of new cybersecurity vulnerabilities and risks.
Our facilities and infrastructure or those of our contract manufacturers or other third-party providers may also be subject to attacks or 
acts of sabotage by outside actors, contractors or employees. Any disruption in our or our contract manufacturers’ manufacturing 
capabilities could delay scaling up production capacity for our drug substances or products or shut down facilities, impose additional 
56

costs, cause us to fail to meet certain product volume or delivery timing obligations, or may require us to identify, qualify and 
establish an alternative manufacturing site, which could adversely affect our business.
As we expand our development and commercial capacities, we have and expect that we will continue to establish additional 
manufacturing capabilities in the United States, as well as in other countries, such as Australia, Canada and the United Kingdom. This 
expansion may lead to regulatory delays or prove more costly than anticipated. If we fail to select suitable locations, complete 
construction in an efficient manner, engage effectively with local regulators, recruit the required personnel or manage our growth 
effectively, the development and production of products or our product candidates could be delayed or curtailed.
Our products and product candidates are sensitive to shipping and storage conditions, which, in some cases, requires cold-chain 
logistics and subjects them to risk of loss or damage.
Our products and product candidates are sensitive to temperature, storage and handling conditions, and we could lose medicines if the 
product or product intermediates are not stored or handled properly. Shelf life for our products and product candidates is variable, and 
they may expire prior to use. Cold-chain logistics are required for certain of our products and product candidates. If we or third-party 
distributors do not maintain effective cold-chain supply logistics, then we may experience returned or out of date products and product 
may be rendered unusable. This has led and could lead to additional manufacturing costs and delays in our ability to supply required 
quantities for clinical trials or commercial sale. In addition, the cost associated with such transportation services and the limited pool 
of vendors could cause supply disruptions.
Our manufacturing facilities or those of our third-party manufacturers or suppliers may fail to meet regulatory requirements. 
Failure to meet cGMP requirements could delay approval of or increase production costs for our products.
The manufacturing of medicines for clinical trials or commercial sale is subject to extensive regulation, and components of such 
products must be manufactured in accordance with cGMP requirements, which are enforced, in the case of the FDA, in part through its 
facilities inspection program. The regulations govern manufacturing processes and procedures, including record keeping, and the 
implementation and operation of quality systems to control and assure the quality of products and materials used in clinical trials. Poor 
control of cGMP production processes can lead to product quality failures that can impact our ability to supply product, resulting in 
cost overruns and delays to clinical timelines, which could be extensive. Such production process issues include:
•
critical deviations in the manufacturing process;
•
facility and equipment failures;
•
contamination of the product due to an ineffective quality control strategy;
•
facility contamination as assessed by the facility and utility environmental monitoring program;
•
raw material failures due to ineffective supplier qualification or regulatory compliance issues at critical suppliers;
•
ineffective product stability;
•
ineffective corrective actions or preventative actions taken to correct or avoid critical deviations due to our developing 
understanding of the manufacturing process as we scale; and
•
failed or defective components or consumables.
Regulators typically require representative manufacturing site inspections to assess adequate compliance with cGMP and 
manufacturing controls. If we or one of our third-party manufacturing sites fails to provide sufficient quality assurance or control, the 
product approval to commercialize may not be granted. Inspections by regulators may occur at any time during the development or 
commercialization of products and may be unannounced. The inspections may be product specific or facility specific, or as a follow up 
to market or development issues that the regulatory agency may identify. Deficient inspection outcomes, such as failure to comply 
with cGMP requirements, may negatively impact the ability of our third-party manufacturers or suppliers to fulfill their supply 
obligations, impacting or delaying supply or delaying programs.
The manufacturing process for our products is subject to regulatory approval. If we or our third-party manufacturers are unable to 
reliably produce products or product candidates to specifications acceptable to regulators, we or our strategic collaborators may not 
obtain or maintain the approvals needed to commercialize such products. Even if regulatory approval is obtained for any of our mRNA 
medicines, there is no assurance that either we or our CMOs will be able to manufacture the approved medicine to specifications 
acceptable to the FDA or other regulators. Any of these challenges could delay completion of clinical trials, require bridging clinical 
trials or the repetition of one or more clinical trials, increase clinical trial costs, delay approval of our product candidates, impair 
commercialization efforts or increase our cost of goods, which, in turn, could have an adverse effect on our business.
In addition, we may not have direct control over the ability of our contract manufacturers to maintain adequate quality control, quality 
assurance and qualified personnel. Our contract manufacturers supply or manufacture materials or products for other companies and 
their failure to meet applicable regulatory requirements may affect the regulatory status of their facilities. In addition, to the extent that 
57

we rely on foreign contract manufacturers, we are subject to additional risks, including the need to comply with import and export 
regulations.
The FDA, the EMA and other foreign regulators may require us to submit product samples of any lot of any approved product, 
together with the protocols showing the results of applicable tests, at any time. In some cases, regulators may prohibit us from 
distributing a lot or lots until it authorizes release. Deviations in the manufacturing process, including those affecting quality attributes 
and stability, may cause unacceptable changes in the product, resulting in lot failures or product recalls. Our third-party contract 
manufacturers have experienced lot failures resulting in product recalls of our COVID vaccine. Lot failures have caused, and lot 
failures or product recalls in the future with respect to product produced by either our own or our third-party manufacturers’ facilities 
could cause, us and our strategic collaborators to delay clinical trials or product launches.
We and our manufacturing partners also may encounter problems hiring and retaining the experienced scientific, quality control and 
manufacturing personnel needed to operate our manufacturing processes and operations or those of our manufacturing partners, which 
could result in delays in production or difficulties in maintaining compliance with applicable regulatory requirements. Additionally, 
we may not be able to control for or detect intentional sabotage or negligence by any employee or contractor.
Our INT product candidates are uniquely manufactured for each patient using a novel, complex manufacturing process and we 
may encounter difficulties in production.
We custom design and manufacture INTs tailored for each patient. Manufacturing unique lots of INTs is susceptible to product loss or 
failure due to issues with:
•
logistics associated with the collection and shipping of a patient’s tumor, blood or other tissue sample;
•
next-generation sequencing of the tumor mRNA and identification of appropriate tumor-specific mutations; 
•
the use of a software program, including proprietary and open source components, which is hosted in the cloud and a part of 
our product candidate, to assist with the design of the patient-specific mRNA, which software must be maintained and 
secured;
•
effective design of the patient-specific mRNA that encodes for the required neoantigens;
•
batch specific manufacturing failures or issues that arise due to the uniqueness of each patient-specific batch;
•
quality control testing failures;
•
unexpected failures of batches placed on stability;
•
shortages or quality control issues with single-use assemblies, consumables or critical parts sourced from third-party vendors 
that must be changed out for each patient-specific batch;
•
significant costs associated with individualized manufacturing that may adversely affect our ability to continue development;
•
successful and timely manufacture and release of the patient-specific batch;
•
shipment issues encountered during transport of the batch to the patient site of care; and
•
the ability to define a consistent safety profile at a given dose when each participant receives a unique therapy.
We have built and installed custom manufacturing equipment for INTs incorporated into a dedicated unit at our Norwood, 
Massachusetts facility. This equipment may not function as designed, resulting in deviations in the drug product produced, which 
could lead to increased batch failure and the inability to supply patients enrolled in a clinical trial. Additionally, as we continue our 
current Phase 3 INT trials, expand to additional tumor types and prepare for commercialization, we anticipate an increase in 
manufacturing demand for our INTs that will require ongoing investments. Some of the additional equipment that will be required will 
be custom-made for us, which will lead to long lead times and expedited procurement to meet our timelines. In addition, it may take 
longer than anticipated to scale up our facilities and to complete our Marlborough, Massachusetts facility (which we expect to dedicate 
to INTs) to meet commercial demand, if our INT product candidate is approved. This expansion and addition of new facilities could 
also lead to product comparability issues, which could further delay introduction of new capacity.
Because our INTs are manufactured for each individual patient, we are required to maintain a chain of identity with respect to each 
patient’s tissue sample, sequence data derived from such tissue sample, results of analysis of such patient’s genomic analysis and the 
custom manufactured product for each patient. Maintaining such a chain of identity is difficult and complex, and failure to do so has 
resulted and may in the future result in product mix up, adverse patient outcomes, loss of product or regulatory action, including 
withdrawal of any approved products from the market. Further, as our INTs are developed through clinical trials towards approval and 
commercialization, we expect that multiple aspects of the complicated collection, analysis, manufacture and delivery process will be 
modified in an effort to optimize processes and results. These changes may not achieve the intended objectives, and any of these 
changes could cause our INTs to perform differently than we expect, potentially affecting the results of clinical trials.
58

Risks related to our reliance on third parties
We are dependent on single-source suppliers for some of the components and materials used in, and the manufacturing processes 
required to develop and commercialize, our products and product candidates.
We cannot ensure that the suppliers we rely on will remain in business, have sufficient capacity or supply to meet our needs or that 
they will not be purchased by one of our competitors or another company that will cease working with us. Our use of single-source 
suppliers exposes us to several risks, including disruptions in supply, price increases, late deliveries or business interruptions. 
There are, in general, few alternative sources of supply for substitute components. If we must switch suppliers, the manufacture and 
delivery of our products or product candidates could be interrupted for an extended period. Establishing additional or replacement 
suppliers for any of the components or processes used in our products or product candidates, if required, may not be accomplished 
quickly, if at all. Any replacement supplier (or us, if we produced directly) would need to be qualified and may require additional 
regulatory approval, resulting in further delay. Any interruption or delay in the supply of components or materials, or our inability to 
obtain components or materials from alternate sources at acceptable prices in a timely manner, could impair our ability to meet the 
demand for our products or product candidates. Additionally, as part of the FDA’s approval of our product candidates, the FDA will 
review the manufacturing processes and facilities of our single-source suppliers.
We have entered, and may enter into, strategic alliances with third parties for product development and commercialization. If these 
alliances are unsuccessful, our business could be adversely affected.
We have entered into strategic alliances with collaborators that have provided, and may in the future provide, funding, intellectual 
property licenses and other resources for developing, manufacturing and commercializing our product candidates. Additionally, we 
have entered into, and may in the future enter into, strategic alliances where we agree to provide funding, intellectual property licenses 
and other resources to third parties. Our existing and any future strategic alliances may pose a number of risks, including:
•
strategic collaborators may not perform their obligations as expected;
•
strategic collaborators may cease or deprioritize development or commercialization of our products due to unfavorable 
clinical trial results, changes in their focus or funding, or other factors that divert their resources or create competing 
priorities, such as potential competition with their own products or candidates;
•
strategic collaborators may delay, stop or provide insufficient funding or resources for clinical trials (whether as a result of a 
business decision or necessitated by financial difficulties of such collaborator);
•
a strategic collaborator with marketing and distribution rights to one or more of our products may commit insufficient 
resources to the marketing and distribution of any such product;
•
disagreements with strategic collaborators, including over proprietary rights, contract interpretation or the course of 
development of any product candidates, may cause delays or termination of the research, development or commercialization 
of such product candidates, lead to additional responsibilities for us with respect to such product candidates or result in 
litigation or arbitration, any of which would be time-consuming and expensive;
•
strategic collaborators may use our proprietary information in such a way as to invite litigation that could jeopardize or 
invalidate our IP or proprietary information;
•
disputes may arise with respect to the ownership of IP developed pursuant to our strategic alliances;
•
strategic collaborators may infringe the IP rights of third parties, exposing us to potential litigation and liability;
•
future relationships may require us to incur non-recurring and other charges, increase our near- and long-term expenditures, 
issue securities that dilute our existing shareholders or disrupt our management and business; 
•
any equity investments we make in collaborators could decrease in value or become worthless; and
•
our international operations through any future collaborations, acquisitions or joint ventures may expose us to certain 
operating, legal and other risks not encountered in the United States.
Our strategic collaborators generally may materially amend or terminate their agreements with us, which has happened in the past. If 
any collaboration agreement is terminated, we may not receive anticipated future research or development funding or milestone, earn-
out royalty, profit share or other contingent payments and the research or development of our product candidates may be delayed or 
discontinued. It may also be difficult to attract new strategic collaborators to continue development or commercialization of the 
applicable product candidate, and our reputation could be adversely affected. All the risks relating to product development, regulatory 
approval and commercialization described elsewhere in these Risk Factors apply to our strategic collaboration activities.
59

We may seek to establish additional strategic alliances and, if we are unable to establish them on commercially reasonable terms, 
we may have to alter our development and commercialization plans. Certain of our strategic alliance agreements may restrict our 
ability to develop certain products.
Our development programs and the potential commercialization of our product candidates will require substantial cash to fund 
expenses. We may collaborate with pharmaceutical and biotechnology companies for the development and potential 
commercialization of some of our product candidates, and we face significant competition in seeking appropriate strategic 
collaborators. Our ability to establish additional strategic alliances will depend, among other things, on our assessment of the 
collaborator’s resources and expertise, the terms and conditions of the proposed strategic alliance and the proposed collaborator’s 
evaluation of a number of factors. Those factors may include the design or results of clinical trials, the likelihood of approval by the 
FDA or foreign regulators, the potential market for the subject product candidate, the costs and complexities of manufacturing and 
delivering such product candidate to trial participants, the potential of competing drugs, the existence of uncertainty with respect to 
our or the proposed collaborator’s ownership of technology, which can exist if there is a challenge to such ownership without regard to 
the merits of the challenge, and industry and market conditions generally.
We are also restricted under some of our existing strategic alliance agreements from entering into agreements on certain terms with 
potential strategic collaborators to pursue other targets on our own. These restrictions on working with targets, polypeptides, routes of 
administration and fields could limit our ability to enter into strategic collaborations with other collaborators or to pursue certain 
potentially valuable product candidates.
Strategic alliances are complex and time-consuming to negotiate and document. If we cannot enter into new strategic alliances on a 
timely basis, on favorable terms or at all, we may need to curtail the development of the product candidate for which we are seeking to 
collaborate, reduce or delay its development program or one or more of our other development programs, delay its potential 
commercialization or reduce the scope of any sales or marketing activities, or increase our expenditures and undertake development or 
commercialization activities at our own expense.
We expect to continue to rely on third parties to conduct aspects of our research, preclinical studies, protocol development and 
clinical trials. If these third parties do not perform satisfactorily or comply with regulatory requirements, we may be unable to 
obtain regulatory approval for or commercialize our product candidates.
We rely on third parties such as CROs to help manage certain preclinical work and our clinical trials, and on medical institutions, 
clinical investigators and CROs to assist in the design and review of, and to conduct, our clinical trials, including enrolling qualified 
patients. In addition, we engage third-party contractors and collaborators to support numerous other research, commercial and 
administrative activities, which reduces our control over these activities but does not relieve us of our responsibilities, such as ensuring 
that each of our clinical trials is conducted in accordance with its general investigational plan and protocols. Moreover, the FDA 
requires us to comply with GLPs and good clinical practices for conducting, recording and reporting the results of preclinical studies 
and clinical trials to assure that data and reported results are credible and accurate and that in the case of clinical trials the rights, 
integrity and confidentiality of trial participants are protected. Such standards will evolve and subject us and third parties to new or 
changing requirements.
If third parties do not successfully carry out their contractual duties or meet expected deadlines, we may need to replace them, which 
could delay the affected clinical trial, drug development program or applicable activity. If clinical trials are not conducted in 
accordance with our contractual expectations or regulatory requirements, action by regulators may significantly and adversely affect 
the conduct or progress of such trials or even require a clinical trial to be redone. Accordingly, our efforts to obtain regulatory 
approvals for and commercialize our drug candidates could be delayed. In addition, failure of any third-party contractor to conduct 
activities in accordance with our expectations could adversely affect the relevant research, development, commercial or administrative 
activity. Failure of any third-party contractor to timely provide access to our data in a format acceptable to us may result in delays or 
impediments to our regulatory submissions or other development activities.
Risks related to our intellectual property
We may be unable to obtain and enforce patent protection for our discoveries and the intellectual property rights therein, or protect 
the confidentiality of our trade secrets.
Our success depends, in part, on our ability to protect proprietary methods and technologies that we develop under the patent and other 
IP laws of the United States and other countries, so that we can prevent others from unlawfully using our inventions and proprietary 
information. Because certain U.S. patent applications are confidential until the patents issue, third parties may have filed patent 
applications for technology covered by our pending patent applications without our being aware of those applications, and our patent 
applications may not have priority over those applications. In addition, publications of discoveries in the scientific literature often lag 
behind the actual discoveries, and patent applications in the United States and other jurisdictions are typically not published until 18 
60

months after filing, if at all. Therefore, we cannot be certain that we were the first to make the inventions claimed in our patents or 
pending patent applications or that we were the first to file for patent protection of such inventions. We therefore may be unable to 
secure desired patent rights, thereby losing exclusivity. In the past, we have obtained licenses under third-party patents to market our 
products or conduct our research and development or other activities, and we may do so in the future if necessary. If licenses are not 
available to us on favorable terms, we may not be able to market the affected products or conduct the desired activities.
The process of obtaining and enforcing patent protection is expensive and time-consuming and our pending patent applications may 
not result in issued patents. Obtaining and maintaining our patent protection depends on compliance with various procedural, 
document submission, fee payment and other requirements imposed by governmental patent agencies, and our patent applications may 
fail to result in valid enforceable patents, or our patent protection could be reduced or eliminated, for non-compliance with these 
requirements. If we or our strategic collaborators fail to file and prosecute all necessary and desirable patent applications at a 
reasonable cost and in a timely manner, our business may be adversely affected.
Despite our and our strategic collaborators’ efforts to protect our proprietary rights, unauthorized parties may obtain and use 
information that we regard as proprietary. While issued patents are presumed valid, they may not survive a validity challenge and 
could be held unenforceable. Any patents we have obtained, or obtain in the future, may be challenged, invalidated, adjudged 
unenforceable or circumvented by parties seeking to design around our IP. Also, third parties or the USPTO may commence patent 
office proceedings involving our patents or patent applications. Any challenge to, finding of unenforceability or invalidation, or 
circumvention of, our patents or patent applications, would be costly, would require significant time and attention of our management, 
could reduce or eliminate royalty payments to us from third-party licensors and could have a material adverse impact on our business.
The standards that the USPTO and its foreign counterparts use to grant patents are not always applied predictably or uniformly and 
can change. Similarly, the ultimate degree of protection that will be afforded to biotechnology inventions, including ours, in the United 
States and foreign countries, remains uncertain and is dependent upon the scope of the protection decided upon by patent offices, 
courts and lawmakers. One major provision of the America Invents Act changed U.S. patent practice from a first-to-invent to a first-
to-file system. If we fail to file an invention before a competitor files on the same invention, we no longer can provide proof that we 
were in possession of the invention prior to the competitor’s filing date, and thus would not be able to obtain patent protection for our 
invention. There is also no uniform, worldwide policy regarding the subject matter and scope of claims granted or allowable in 
pharmaceutical or biotechnology patents. In certain countries, for example, methods for the medical treatment of humans are not 
patentable.
Accordingly, we do not know the degree of future protection for our proprietary rights or the breadth of claims that will be allowed in 
any patents issued to us or to others. We also rely to a certain extent on trade secrets, know-how and technology, which are not 
protected by patents, to maintain our competitive position. We also rely on non-disclosure agreements and invention assignment 
agreements with our employees, consultants and third parties. If any trade secret, know-how or other technology not protected by a 
patent were to be disclosed to or independently developed by a competitor, our business and financial condition could be materially 
adversely affected.
Failure to obtain and maintain all available regulatory exclusivities and broad patent scope and to maximize patent term restoration or 
extension on patents covering our products may lead to loss of exclusivity and early biosimilar entry resulting in a loss of market share 
or revenue.
In addition, we may choose not to enforce our IP rights in certain circumstances or for certain periods of time. For example, in March 
2022, we announced that we will not enforce our patents for COVID vaccines against companies manufacturing in or for the Gavi 
COVAX Advance Market Commitment (AMC) countries, provided that the manufactured vaccines are solely for use in the AMC 92 
countries. In addition, we are willing to license our IP for COVID vaccines to manufacturers, but licensing of our IP may be limited, 
and our business may be otherwise adversely impacted if we are unable to enforce our IP.
Uncertainty over IP in the pharmaceutical and biotechnology industry has been the source of litigation and other disputes, which 
is inherently costly and unpredictable and can have adverse financial and freedom-to-operate consequences.
mRNA medicines are a relatively new scientific field and, as the field continues to mature, patent applications are being processed by 
national patent offices globally. There is uncertainty about which patents will issue, and, if they do, as to when, to whom and with 
what claims. Litigation is ongoing over the underlying technology to mRNA medicines between many mRNA market participants. It 
is likely that there will continue to be significant litigation and patent office proceedings in various patent offices relating to patent 
rights in the mRNA field.
We have issued patents and pending patent applications in the United States and in key markets around the world that claim many 
different methods, compositions and processes relating to the discovery, development, manufacture and commercialization of mRNA 
medicines and our delivery technology, including LNPs. Oppositions and inter partes review petitions have been filed against some of 
61

our patents, and we expect that further proceedings will be filed in the European Patent Office (EPO), USPTO and elsewhere relating 
to patents and patent applications in our portfolio. In many cases, the possibility of appeal exists for any party, and it may be years 
before final, unappealable rulings are made with respect to these patents in certain jurisdictions. The timing and outcome of these and 
other proceedings is uncertain and may adversely affect our business if we are not successful in defending the patentability and scope 
of our pending and issued patent claims. We cannot be certain that any patent will survive or that the claims will remain in the current 
form. Even if our rights are not directly challenged, disputes could lead to the weakening of our IP rights.
In certain instances, we have instituted and may in the future institute inter partes review proceedings against issued U.S. patents and 
opposition proceedings against European patents owned by third parties in the field of mRNA medicines. We have a number of these 
proceedings ongoing against third-party patents. If we are unsuccessful in narrowing or invalidating such third-party patents, those 
third parties may attempt to assert those patents against our products. As the biotechnology and pharmaceutical industries expand and 
more patents are issued, the risk increases that our products or product candidates may be subject to claims of infringement of the 
patent rights of third parties.
We have invested billions of dollars in creating our patented mRNA platform, which is integral to the development of our mRNA 
medicines, and we are involved in various intellectual property litigation as described under Part I, Item 3, “Legal Proceedings.” We 
expect to expend substantial financial and managerial resources in connection with these legal proceedings, and the ultimate outcome 
of each proceeding is uncertain.
We are, and may in the future become, involved in patent litigation or other proceedings related to a determination of rights, we 
could incur substantial costs and expenses, substantial liability for damages or be required to stop our product development and 
commercialization efforts.
There may be third-party patents or patent applications with claims to materials, formulations, methods of manufacture or methods for 
treatment related to the use or manufacture of our products and product candidates, and third parties may assert that we are employing 
their proprietary technology without authorization. In addition, third parties may obtain patents in the future and claim that our 
technologies infringe upon these patents. If any third-party patents were held by a court of competent jurisdiction to cover the 
manufacturing process of any of our products or product candidates, any molecules formed during the manufacturing process or any 
final product itself, the holders of any such patents may obtain injunctive or other equitable relief, which could effectively block our 
ability to commercialize such product unless we obtained a license under the applicable patents, or until such patents expire. Similarly, 
if any third-party patents were held by a court of competent jurisdiction to cover aspects of our formulations, processes for 
manufacture or methods of use, including combination therapy, the holders of any such patents may be able to block our ability to 
develop and commercialize the applicable product or product candidate unless we obtained a license or until such patent expires.
Defense of infringement and other claims, regardless of their merit, involves substantial litigation expense and diverts employee 
resources from our business. In the event of a successful infringement claim against us, we may have to pay substantial damages, 
including treble damages and attorneys’ fees for willful infringement, pay royalties, redesign our infringing products or obtain one or 
more licenses from third parties, which may not be made available on commercially favorable terms, if at all, or may require 
substantial time and expense.
In addition, any such licenses are likely to be non-exclusive and, therefore, our competitors may have access to the same technology 
licensed to us. If we fail to obtain a required license and are unable to design around a patent, we may be unable to effectively market 
some of our technology and products, which could limit our ability to generate revenues or achieve profitability, which could 
jeopardize our ability to sustain our operations. Moreover, we expect that a number of our collaborations will provide that royalties 
payable to us for licenses to our IP may be offset by amounts paid by our collaborators to third parties who have competing or superior 
IP positions in the relevant fields, which could result in significant reductions in our revenues from products developed through 
collaborations.
In addition, in connection with certain license and strategic alliance agreements, we have agreed to indemnify certain third parties for 
certain costs incurred in connection with litigation relating to IP rights or the subject matter of the agreements. The cost to us of any 
litigation or other proceeding relating to IP rights, even if resolved in our favor, could be substantial, and litigation would divert our 
management’s efforts. Some of our competitors may be able to sustain the costs of complex patent litigation more effectively than we 
can because they have substantially greater resources. Uncertainties resulting from the initiation and continuation of any litigation 
could delay our research, development and commercialization efforts and limit our ability to continue our operations.
If third-party owners of any patent rights that we license do not properly or successfully obtain, maintain or enforce the patents 
underlying such licenses, our competitive position and business prospects may be harmed.
We may become party to licenses that give us rights to third-party IP necessary or useful for our business and our success may depend 
in part on the ability of our licensors to obtain, maintain and enforce patent protection for our licensed IP. Our licensors may fail to 
62

successfully prosecute the patent applications we license, fail to maintain these patents, determine not to pursue litigation against other 
companies that are infringing these patents or pursue such litigation less aggressively than we would. Without protection for the IP we 
license, other companies might be able to offer substantially identical products for sale, which could adversely affect our competitive 
business position and harm our business prospects. In addition, we sublicense our rights under various third-party licenses to our 
strategic collaborators. Any impairment of these sublicensed rights could result in reduced revenues under our strategic alliance 
agreements or result in termination of an agreement by one or more of our strategic collaborators.
If we fail to comply with our obligations in the agreements under which we license IP rights from third parties or otherwise 
experience disruptions to our business relationships with our licensors, we could lose license rights that are important to our 
business.
We license IP, which involves complex legal, business and scientific issues and is complicated by the rapid pace of scientific 
discovery in our industry. We are a party to certain IP license agreements and expect to enter into additional license agreements in the 
future. Our existing license agreements impose, and we expect that future license agreements will impose, various diligence, milestone 
payment, royalty and other obligations on us. If we fail to comply with our obligations under these agreements, or we are subject to a 
bankruptcy, the licensor may have the right to terminate the license, in which event we would not be able to market products covered 
by the license and may be subject to additional liabilities.
In certain cases, we control the prosecution of patents resulting from licensed technology. In the event we breach any of our 
obligations related to such prosecution, we may incur significant liability to our strategic collaborators. Disputes may arise regarding 
IP subject to a licensing agreement, including:
•
the scope of rights granted under the license agreement and other interpretation-related issues;
•
whether our technology and processes that are not subject to the licensing agreement infringe on IP of the licensor;
•
the sublicensing of patent and other rights under our collaborative development relationships;
•
our diligence obligations under the license agreement and what activities satisfy those diligence obligations;
•
the ownership of inventions and know-how resulting from the joint creation or use of IP by our licensors and us and our 
strategic collaborators; and
•
the priority of invention of patented technology.
If disputes over IP that we have licensed prevent or impair our ability to maintain our current licensing arrangements on favorable 
terms, we may be unable to successfully develop and commercialize the affected product candidates. We are generally also subject to 
all of the same risks with respect to protection of IP that we license as we are for IP that we own. If we or our licensors fail to 
adequately protect this IP, our ability to commercialize products could suffer.
We may be subject to claims that our employees, consultants or independent contractors have wrongfully used or disclosed 
confidential information of third parties or that our employees have wrongfully used or disclosed alleged trade secrets of their 
former employers.
We employ individuals who were previously employed at universities or other biotechnology or pharmaceutical companies, including 
our competitors or potential competitors. From time to time, we are subject to claims that we or our employees, consultants or 
independent contractors have inadvertently or otherwise used or disclosed IP, including trade secrets or other proprietary information, 
of third parties, including our employees’ former employers. Litigation may be necessary to defend against these claims. If we fail to 
defend such claims, in addition to paying monetary damages, we may lose valuable IP rights or personnel, which could adversely 
impact our business. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a 
distraction to management and other employees.
We may be subject to claims challenging the inventorship or ownership of our patents and other IP.
We may be and have been subject to claims that former employees, collaborators or other third parties have an ownership interest in 
our patents or other IP. Ownership disputes may arise, for example, from conflicting obligations of consultants or others who are 
involved in developing our product candidates. Litigation may be necessary to defend against these and other claims challenging 
inventorship or ownership. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable IP 
rights, including exclusive ownership of, or right to use, valuable IP. Such an outcome could have a material adverse impact on our 
business. Even if we are successful in defending against such claims, litigation could result in substantial costs and distract 
management and other employees, and could impact or patenting strategy.
63

Changes in U.S. patent and regulatory law could impair our ability to protect our products.
Our success is heavily dependent on IP, particularly patents. U.S. patent law continues to evolve, and certain U.S. Supreme Court 
rulings have narrowed the scope of patent protection available in certain circumstances and weakened the rights of patent owners in 
certain situations. These rulings have increased uncertainty regarding our ability to obtain patents in the future, as well as with respect 
to the value of patents, once obtained. Depending on actions or decisions by the U.S. Congress, the federal courts and the USPTO, the 
laws and regulations governing patents could change in unpredictable ways that would weaken our ability to obtain new patents or to 
enforce our existing patents and patents that we might obtain in the future. 
We may be unable to protect our IP rights throughout the world.
Filing, prosecuting and defending patents in every country would be prohibitively expensive, and our foreign IP rights can be less 
extensive than those in the United States. In addition, the laws of some foreign countries do not protect IP rights to the same extent as 
U.S. federal and state laws. Consequently, we may be unable to prevent third parties from practicing our inventions in all countries 
outside the United States, or from selling or importing products made using our inventions in and into the United States or other 
jurisdictions. Competitors may use our technologies to develop their own products in jurisdictions where we have not obtained patent 
protection or may export infringing products to territories where we have patent protection, but enforcement is not as strong as in the 
United States.
Many companies have encountered significant problems in protecting and defending IP rights in foreign jurisdictions. The legal 
systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents, trade secrets and other 
IP protection, particularly those relating to biotechnology products, which could make it difficult for us to stop the infringement of our 
patents or marketing of competing products in violation of our proprietary rights generally. Proceedings to enforce our patent rights in 
foreign jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of our business, could put 
our patents at risk of being invalidated or interpreted narrowly and our patent applications at risk of not issuing and could provoke 
third parties to assert claims against us. We may not prevail in any lawsuits that we initiate and the damages or other remedies 
awarded, if any, may not be commercially meaningful. Accordingly, our efforts to enforce our IP rights around the world may be 
inadequate to obtain a significant commercial advantage from the IP that we develop or license.
Additionally, many countries have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third 
parties. For example, during the COVID pandemic, certain countries threatened steps to facilitate compulsory licenses to permit the 
distribution of a COVID vaccine in those countries. In addition, many countries limit the enforceability of patents against government 
agencies or government contractors. In these countries, the patent owner may have limited remedies, which could materially diminish 
the value of the relevant patent rights. If we or any of our licensors is forced to grant a license to third parties with respect to any 
patents relevant to our business, our competitive position may be impaired.
Our reliance on government funding and collaboration from governmental and quasi-governmental entities for certain of our 
programs adds uncertainty to our research and development efforts with respect to those programs and may impose requirements 
related to IP rights and requirements that increase the costs of development, commercialization and production of any programs 
developed under those government-funded programs.
Contracts and grants funded by the U.S. government and its agencies, including our agreements funded by BARDA and DARPA and 
our collaboration with NIAID, include provisions that reflect the government’s substantial rights and remedies, many of which are not 
typically found in commercial contracts, including powers of the government to:
•
terminate agreements, in whole or in part, for any or no reason;
•
reduce or modify the government’s obligations under such agreements without our consent;
•
claim rights, including IP rights, in products and data developed under such agreements;
•
audit contract-related costs and fees, including allocated indirect costs;
•
suspend the contractor or grantee from receiving new contracts pending resolution of alleged violations of procurement laws 
or regulations;
•
impose U.S. manufacturing requirements for products that embody inventions conceived or first reduced to practice under 
such agreements;
•
suspend or debar the contractor or grantee from doing future business with the government;
•
control and potentially prohibit the export of products;
•
pursue criminal or civil remedies under the False Claims Act, False Statements Act and similar remedy provisions specific to 
government agreements; and
•
limit the government’s financial liability to amounts appropriated by the U.S. Congress on a fiscal-year basis, thereby leaving 
some uncertainty about the future availability of funding for a program even after it has been funded for an initial period.
64

We may not have the right to prohibit the U.S. government from using certain technologies developed by us and we may be unable to 
prohibit other companies, including our competitors, from using those technologies in providing products and services to the U.S. 
government. The U.S. government generally takes the position that it has the right to royalty-free use of technologies that are 
developed under U.S. government contracts.
In addition, government contracts and grants, and subcontracts and subawards awarded in the performance of those contracts and 
grants, normally contain additional requirements that may increase our costs of doing business, reduce our profits and expose us to 
liability for failure to comply with these terms and conditions. These requirements include, for example:
•
specialized accounting systems unique to government contracts and grants;
•
mandatory financial audits and potential liability for price adjustments or recoupment of government funds after such funds 
have been spent;
•
public disclosures of certain contract and grant information, which may enable competitors to gain insights into our research 
program; and
•
mandatory socioeconomic compliance requirements, including labor standards, non-discrimination, and affirmative action 
programs and environmental compliance requirements.
Further, under these agreements we are subject to the obligations to and the rights of the U.S. government set forth in the Bayh-Dole 
Act of 1980 (Bayh-Dole Act). As a result, the U.S. government may have rights in certain inventions developed under these 
government-funded programs, including a non-exclusive, non-transferable, irrevocable worldwide license to use inventions for any 
governmental purpose. In addition, the U.S. government has the right to require us to grant exclusive, partially exclusive or 
nonexclusive licenses to any of these inventions to a third party if it determines that: (i) adequate steps have not been taken to 
commercialize the invention; (ii) government action is necessary to meet public health or safety needs; or (iii) government action is 
necessary to meet requirements for public use under federal regulations, also referred to as “march-in rights.”
Any exercise of the march-in rights by the U.S. government could harm our competitive position, business, financial condition, results 
of operations and prospects. In December 2023, the Biden administration released a proposed framework specifying for the first time 
that price can be a factor in considering whether an invention is sufficiently available to the public. The proposed framework could 
potentially enable march-in rights to be used as a tool to regulate drug pricing. The potential inclusion of price as a factor in a march-
in determination is expected to draw extensive criticism and challenge, and the ultimate impact is currently unknown. If the U.S. 
government exercises such march-in rights, we may receive compensation deemed reasonable by the U.S. government in its sole 
discretion, which may be less than what we might be able to obtain in the open market. IP generated under a government-funded 
program is also subject to certain reporting requirements, compliance with which may require us to expend substantial resources.
We have significant contracts with the U.S. and other governments, and as such are subject to related regulatory compliance 
obligations. If we fail to maintain compliance with those obligations, we may be subject to potential liability and to termination of our 
contracts.
Risks related to our financial condition and results of operations
We incurred net losses in 2024 and 2023, and expect to incur additional losses in the future; we may not achieve long-term 
sustainable profitability.
We incurred net losses of $3.6 billion and $4.7 billion in 2024 and 2023, respectively, and other than in 2022 and 2021, we have 
incurred net losses in each year since our inception. Currently, our COVID and RSV vaccines are our only commercial products and 
our RSV sales have been minimal. While preparations are underway for additional potential product launches, the ultimate occurrence 
and timing of these launches is uncertain. Our ability to generate revenue and achieve profitability depends on our ability to 
successfully develop and obtain the regulatory approvals necessary to commercialize our products.
We have incurred, and expect to continue to incur, significant costs associated with commercializing our products and our clinical 
development activities. Although we continue to implement cost efficiency and prioritization measures, we may be unsuccessful in 
reducing our costs in line with our expectations, which could require us to seek additional funding to continue operations. Our 
expenses could increase for many reasons, including if and as we:
•
initiate additional clinical trials, particularly large pivotal trials;
•
continue to build out our manufacturing capabilities;
•
build out a sales, marketing and distribution infrastructure to commercialize any products;
•
acquire or in-license other product candidates and technologies; and
•
experience any delays or encounter issues with any of the above.
65

Our quarterly and annual operating results may fluctuate. As a result, we may fail to meet or exceed the expectations of research 
analysts or investors, which could cause our stock price to decline and negatively impact our financing or funding ability, as well 
as our ability to exist as a standalone company.
Our financial condition and operating results may fluctuate from quarter-to-quarter and year-to-year due to many factors, many of 
which are beyond our control. As such, a period-to-period comparison of our operating results may not be predictive of our future 
performance. In any particular quarter, our operating results could be below the expectations of securities analysts or investors, which 
could cause our stock price to decline. Our stock price could be affected by events not necessarily tied to our actual operating results, 
including recommendations by securities analysts, the timing of certain public disclosures by us, our collaborators or our competitors 
and our ability to accurately report our financial results in a timely manner. Other factors relating to our business that may contribute 
to these fluctuations include those described in these Risk Factors and elsewhere in this Annual Report on Form 10-K.
The investment of our cash, cash equivalents and investments is subject to risks which may cause losses and affect the liquidity of 
these investments.
As of December 31, 2024, we had approximately $9.5 billion in cash, cash equivalents and investments, which are subject to general 
credit, liquidity, market, inflation and interest rate risks. We may realize losses in the fair value of these investments. In addition, if our 
investments cease paying or reduce the amount of interest paid to us, our interest income would suffer. These and other market risks 
associated with our investment portfolio may adversely affect our results of operations, liquidity and financial condition.
Risks related to our business and operations
We may encounter difficulties in managing the development and expansion of our company.
We have expanded our scope of operations and number of employees rapidly over the last several years and we must continue to 
implement and improve our managerial, operational and financial systems. Our management may need to divert significant attention 
away from our day-to-day activities to manage these development activities.
Successfully developing products for and fully understanding the regulatory and manufacturing pathways for the many therapeutic 
areas and diseases we seek to address requires significant depth of talent, resources and corporate processes to allow simultaneous 
execution across multiple areas. We may be unable to effectively manage this simultaneous execution and expansion of our operations 
or recruit and train qualified personnel, which could cause weaknesses in our infrastructure, give rise to operational mistakes, loss of 
business opportunities, loss of employees and reduced productivity among remaining employees. The physical expansion of our 
operations, including the expansion of our Norwood and Marlborough campuses in Massachusetts and the construction of 
manufacturing facilities overseas, may lead to significant costs and may divert financial resources from other projects, such as the 
development of our product candidates. If our management is unable to effectively manage our development and expansion, our 
financial performance and ability to commercialize our products may be affected negatively.
We are subject to the risks of doing business outside of the United States.
Our business is subject to risks associated with doing business outside of the United States. We are not permitted to market or promote 
any of our product candidates before we receive regulatory approval or other authorization from an applicable authority, and we may 
never receive such approval. To obtain regulatory approval in various jurisdictions, we must comply with numerous regulatory 
requirements regarding safety and efficacy and governing, among other things, clinical trials, manufacturing, commercial sales, 
pricing and distribution of our product candidates, and we may fail to obtain approval. We have rapidly expanded our global 
operations, establishing commercial subsidiaries and entering into arrangements to support the worldwide manufacture and 
distribution of our products, which is a complex task. For example, we are building regional manufacturing facilities and investing in 
research and development in several countries. Our business may be adversely affected by many factors associated with our expanding 
global business, including:
•
efforts to develop an international commercial sales, marketing and supply chain and distribution organization, including 
efforts to mitigate longer accounts receivable collection times, longer lead times for shipping and potential language barriers; 
•
our customers’ ability to obtain reimbursement for our products in foreign markets;
•
our inability to directly control commercial activities because we rely on third parties;
•
different medical practices and customs in foreign countries affecting acceptance in the marketplace;
•
changes in a specific country’s or region’s political and cultural climate or economic condition;
•
an increased legal and compliance burden to establish, maintain and operate legal entities in foreign countries;
•
the burden of complying with complex and changing foreign regulatory, tax, accounting, reporting and legal requirements, 
including the European General Data Protection Regulation 2016/679 (GDPR);
66

•
the interpretation of contractual provisions governed by foreign laws in the event of a contract dispute, and the difficulty of 
effective enforcement of contractual provisions in local jurisdictions;
•
inadequate IP protection in foreign countries and the existence of potentially relevant third-party IP rights;
•
trade-protection measures including trade restrictions, import or export licensing requirements such as Export Administration 
Regulations promulgated by the U.S. Department of Commerce and fines, penalties, or suspension or revocation of export 
privileges, the imposition of government controls and changes in tariffs;
•
the effects of applicable foreign tax structures and potentially adverse tax consequences; and
•
significant adverse changes in foreign currency exchange rates.
We are also subject to extensive federal, state and foreign anti-bribery regulations, including the U.S. Foreign Corrupt Practices Act 
(FCPA), the UK Bribery Act and similar laws in other countries. Compliance with the FCPA is expensive and difficult, particularly in 
countries where corruption is a recognized problem. Additionally, the FCPA presents particular challenges to the pharmaceutical 
industry because, in many countries, hospitals are operated by the government, and doctors and other hospital employees are 
considered foreign officials. Certain payments to hospitals in connection with clinical trials and other work have been deemed to be 
improper payments to government officials and have led to FCPA enforcement actions. Various laws, regulations and executive orders 
also restrict the use and dissemination outside the United States, or the sharing with certain non-U.S. nationals, of information 
classified for national security purposes, as well as certain products and technical data relating to those products. As we expand our 
presence outside the United States, we will need to dedicate additional resources to comply with these laws, and these laws may 
preclude us from developing, manufacturing or selling certain products and product candidates outside the United States, which could 
limit our growth potential and increase our development costs.
Additionally, in many jurisdictions outside the United States, we have or may become subject to additional industry-specific codes of 
conduct that impose additional compliance responsibilities on us. Failure to comply with these codes particularly as we enter new 
markets has, and could in the future, result in findings against us, which could result in financial sanctions or reputational harm.  
We cannot guarantee that we, or our employees, consultants or third-party contractors are or will be in compliance with all federal, 
state and foreign regulations regarding bribery and corruption. Moreover, our strategic collaborators and third-party contractors 
outside the United States may have inadequate compliance programs or fail to respect the laws and guidance of the territories where 
they operate, which may result in substantial civil and criminal penalties and suspension or debarment from government contracting. 
The SEC also may suspend or bar issuers from trading securities on U.S. exchanges for violations of the FCPA’s accounting 
provisions. Even if we are not determined to have violated these laws, government investigations typically require the expenditure of 
significant resources and generate negative publicity.
Our failure to maintain our enterprise resource planning (ERP) system could adversely impact our business and results of 
operations.
Any disruptions or difficulties using our newly upgraded global ERP system could adversely affect our controls, resulting in harm to 
our business, including our ability to forecast or make sales and collect our receivables. Significant delays in documenting, reviewing 
and testing our internal controls could cause our non-compliance with our SEC reporting obligations related to our management’s 
assessment of our internal control over financial reporting, resulting in unanticipated costs and the diversion of management’s 
attention.
Our success depends on our ability to retain key employees, consultants and advisors and to attract, retain and motivate qualified 
personnel.
Our ability to compete in the highly competitive biotechnology and pharmaceutical industries depends on our ability to attract and 
retain highly qualified managerial, scientific, technical, quality-control, manufacturing, medical, regulatory and commercial personnel. 
The turnover rate in our industry is high and we compete with other companies, as well as academic institutions, for individuals with 
certain skill sets. Failure to attract and retain personnel, or to maintain relationships with key consultants, contractors and advisors, 
could result in delays in production or difficulties in maintaining compliance with regulatory requirements. In addition, negative 
business developments may make it difficult to recruit and retain qualified personnel.
We are highly dependent on members of our management and scientific teams. Each of our executive officers and key employees are 
employed “at will,” and the loss of any of their services may adversely impact the achievement of our business objectives. We do not 
have “key person” insurance on any of our employees. Several of our executives have valuable, fully vested stock options or other 
long-term equity awards. Additionally, significant declines in our stock price have in the past reduced, and may in the future reduce, 
the retentive power of equity awards for our executives or other key personnel. We may not be able to retain these employees due to 
the competitive environment in the biotechnology industry, particularly in Cambridge, Massachusetts.
67

If we cannot maintain our corporate culture, we could lose the innovation, teamwork and passion that we believe contribute to our 
success.
It may be increasingly difficult to maintain our culture, which we have invested substantial resources in building. The dramatic growth 
of our workforce, coupled with recent shifts in workplace and workstyle, increase this risk. Any failure to preserve our culture could 
negatively affect our future success, including our ability to retain and recruit personnel and to effectively pursue our strategic plans.
Our internal computer systems and physical premises, or those of third parties with which we share sensitive data or information, 
may fail or suffer security breaches, including from cybersecurity incidents, which could materially disrupt our product 
development programs and manufacturing operations.
Our internal computer systems and infrastructure and those of our strategic collaborators, vendors, contractors, consultants or 
regulators with whom we share confidential, protected or sensitive data or information, or upon which our business relies, are 
vulnerable to damage from computer viruses, unauthorized access, misuse, natural disasters, terrorism, cybersecurity threats, war and 
telecommunication and electrical failures, as well as security compromises or breaches, which may compromise our systems, 
infrastructure, data or that of those with whom we share such data or information or upon which our business relies, or lead to data 
compromise, misuse, misappropriation or leakage. We have experienced, and may experience additional, cyber-attacks on our 
information technology systems and infrastructure by threat actors of all types (including nation states, criminal enterprises, individual 
actors or advanced persistent threat groups). In addition, we may experience intrusions on our physical premises by these threat actors. 
In addition to extracting sensitive information, such attacks could include the deployment of harmful malware, ransomware, digital 
extortion, business email compromises and denial-of-service attacks, social engineering (including phishing attacks) and other means 
to affect server reliability and threaten the confidentiality, integrity and availability of information, systems or infrastructure. If any 
such cyber-attack or physical intrusion against us or those with whom we share confidential, protected or sensitive data or information, 
or upon which our business relies, were to result in a loss of or damage to our data, systems or infrastructure, or interrupt our 
operations, such as a material disruption of our development programs or our manufacturing operations, or due to a loss of any of our 
proprietary or confidential information, it would have a material adverse effect on us. For example, the loss of clinical trial data could 
delay our regulatory approval efforts and increase our costs to recover or reproduce the data. In addition, because we run multiple 
clinical trials in parallel, any breach or compromise of our computer systems or infrastructure or physical premises may result in a loss 
of data or compromised data integrity across multiple programs in many stages of development. While we seek to take steps to address 
cybersecurity risks, our efforts may not wholly mitigate such risks. Further, our contracts may not contain limitations of liability, and 
even where they do, there can be no assurance that limitations of liability in our contracts are sufficient to protect us from liabilities, 
damages or claims related to our privacy and data security obligations. Further, although we maintain cyber liability insurance, this 
insurance may not provide adequate coverage against potential liabilities related to any experienced cybersecurity incident or breach. 
Any data breach, security incident or compromise of confidential, protected or personal information, including any clinical trial 
participant personal data, may also result in notification requirements or other disclosure obligations and may subject us to civil fines 
and penalties, litigation, regulatory investigations or enforcement actions, or claims for damages under the GDPR and UK GDPR and 
relevant member state law in the EU, other foreign laws, and the federal Health Insurance Portability and Accountability Act of 1996 
(HIPAA), and other relevant state and federal privacy laws in the United States including the California Consumer Privacy Act, as 
amended by the California Privacy Rights Act (the CCPA). We have from time to time received information that companies working 
on vaccine research and development may be a particular focus for those planning cyberattacks, including by nation states and 
affiliated cyber actors. To the extent that any disruption or security compromise incident or breach were to result in a loss of, or 
damage to, our data, systems, infrastructure or applications, or inappropriate use or disclosure of confidential or proprietary 
information, including information related to the research and manufacturing of our products, we could incur liability, our competitive 
and reputational position could be harmed and the further development and commercialization of our product candidates could be 
delayed.
We may use our financial and human capital to pursue a particular research program or product candidate and fail to capitalize 
on programs that may be more profitable or for which there is a greater likelihood of success.
We pursue and fund the development of selected research programs or product candidates and may choose to forego or delay pursuit 
of other opportunities that could later prove to have greater commercial potential. For example, we are currently focusing our efforts 
on certain prioritized programs that we expect to file for approval over the next several years. Our resource allocation decisions, or our 
contractual commitments to provide resources to our strategic collaborators, may cause us to fail to capitalize on certain other 
commercial products or profitable market opportunities. Additionally, spending on research and development programs for product 
candidates may not yield commercially viable products. We may also seek to enter into strategic collaborations or financing 
arrangements pursuant to which we may relinquish valuable rights to product candidates, including the rights to a portion of future 
revenues, through a strategic alliance, licensing or other royalty arrangements in cases where it would have been more advantageous 
for us to retain sole development and commercialization rights. Additionally, we may allocate internal resources to a product candidate 
in a therapeutic area in which it would have been more advantageous to enter into a strategic alliance.
68

If we are not successful in discovering, developing and commercializing additional products, our ability to expand our business 
and achieve our strategic objectives would be impaired.
A key element of our longer-term strategy is to discover, develop and commercialize products beyond our current portfolio to treat 
various conditions and in a variety of therapeutic areas. We intend to do so by investing in our drug discovery efforts, exploring 
potential strategic alliances for the development of new products and in-licensing technologies. Identifying new product candidates 
requires substantial technical, financial and human resources. We may fail to identify promising candidates or to successfully develop 
and commercialize products for many reasons, which would impair our potential for growth.
Our business could be harmed if we suffer damage to our reputation, including as a result of a product recall.
The FDA or foreign regulators could require the recall of our products. The FDA has authority to recall a biologic product if it finds 
that a batch, lot or other quantity of the biologic product presents an imminent or substantial hazard to the public health. In addition, 
foreign governmental bodies may require the recall of any products in the event of material deficiencies or defects in design or 
manufacture. Manufacturers may independently recall a product if a material deficiency in a product is found. A government-
mandated or voluntary recall by us or our strategic collaborators could occur because of manufacturing errors, design or labeling 
defects or other deficiencies and issues, as occurred with the recall in 2021 of certain batches of our COVID vaccine shipped to Japan 
that were found to contain foreign particulate. Recalls of any of our products would divert managerial and financial resources and 
adversely affect our financial condition and results of operations. A recall announcement could harm our reputation and negatively 
affect our sales. Our reputation could be further impacted by public discourse regarding our business and perception of our business 
strategy.
Product liability lawsuits against us could cause us to incur substantial liabilities and limit commercialization of our products.
We are exposed to product liability risk related to the development, testing, manufacturing and marketing of our products and product 
candidates in clinical trials. Product liability claims and related cross-claims and claims for indemnification may be brought against us 
by patients, healthcare providers or others using, prescribing, selling or otherwise coming into contact with our products or product 
candidates. For example, we may be sued if any product or product candidate allegedly causes injury or is found to be otherwise 
unsuitable during clinical trials, manufacturing or, if approved, marketing, sale or commercial use. If we cannot successfully defend 
ourselves against such claims, we could incur substantial liabilities.
We could also face product liability claims relating to the worsening of a patient’s condition, injury or death alleged to have been 
caused by our products or product candidates. Any such claims may include allegations of defects in manufacturing or design, a failure 
to warn of dangers inherent in the product, including due to interactions with alcohol or other drugs, knowledge of risks, negligence, 
strict liability and a breach of warranties. Claims could also be asserted under state consumer protection acts. Such claims might not be 
fully covered by product liability insurance. For any marketed products, product liability claims could result in an FDA investigation 
of the safety and effectiveness of our products, our manufacturing processes and facilities or our marketing programs, and potentially a 
recall of our products or more serious enforcement action, limitations on the approved indications for which they may be used, 
suspension or withdrawal of approvals or license revocation. Regardless of the merits or eventual outcome, liability claims may cause 
decreased demand for our products, injury to our reputation and significant negative media attention, costs to defend the related 
litigation, withdrawal of clinical trial participants, loss of revenue, a diversion of management’s time and our resources, substantial 
monetary awards to trial participants, patients or their family members, payments to indemnify clinical trial sites and other clinical 
trial partners and a decline in our stock price. On occasion, large judgments have been awarded in individual, mass tort and class-
action lawsuits based on drugs or medical treatments that had unanticipated adverse effects.
With respect to our COVID vaccine, although the U.S. and certain foreign governments contractually agreed to indemnify us or make 
statutory immunity available to us for sales during the pandemic public health emergency, such indemnification or statutory immunity 
may be unavailable to cover potential claims or liabilities resulting from the research, development, manufacture, distribution or 
commercialization of the vaccine. Additionally, other foreign governments that we contract with have not provided us with similar 
contractual indemnity or statutory immunity, and we generally no longer have the benefit of such indemnities or immunities for future 
sales of our commercial products. Substantial claims arising from the vaccine outside the scope of or in excess of U.S. or foreign 
government indemnity or statutory immunity could harm our financial condition and operating results. Moreover, any adverse event or 
injury for which we are liable, even if fully covered under an indemnity or immunity, could negatively affect our reputation.
We may be unable to maintain our product liability insurance coverage at a reasonable cost or in sufficient amounts to protect us 
against losses due to liability. If the costs of maintaining adequate insurance coverage increase significantly in the future, our 
operating results could be materially adversely affected. Likewise, if insurance coverage should become unavailable to us or become 
economically impractical, we would be required to operate our business without indemnity from commercial insurance providers. 
Additionally, even if we maintain insurance coverage for a type of liability, a particular claim may not be covered if it is subject to a 
69

coverage exclusion or we do not otherwise meet the conditions for coverage. If we operate our business with inadequate insurance, we 
could be responsible for paying claims or judgments against us, which could adversely affect our results of operations or financial 
condition.
Federal legislation and actions by federal, state and local governments may permit reimportation into the United States of drugs 
from foreign countries where the drugs are sold at lower prices.
We may face competition in the United States for our products from therapies sourced from foreign countries with price controls on 
pharmaceutical products. For example, in October 2020, the FDA published a final rule that would allow for the importation of certain 
prescription drugs from Canada, where there are government price controls. In January 2024, the FDA approved Florida’s request to 
import certain lower-priced medications from Canada. While the full implications of the final rule are currently unknown, legislation 
or regulations allowing the reimportation of drugs could decrease the price we receive for any products we may develop and adversely 
affect our future revenues and potential profitability.
Healthcare legislative reform discourse and potential or enacted measures may have a material adverse impact on our business 
and results of operations and legislative or political discussions surrounding the desire for and implementation of pricing reforms 
may adversely impact our business.
In the United States, federal and state legislatures, health agencies and third-party payors continue to focus on containing the cost of 
health care. Legislative and regulatory proposals, enactments to reform health care insurance programs and increasing pressure from 
social sources could significantly influence the manner in which our products are prescribed and purchased. For example, provisions 
of the ACA have resulted in changes in the way health care is paid for by both governmental and private insurers, including increased 
rebates owed by manufacturers under the Medicaid Drug Rebate Program, annual fees and taxes on manufacturers of certain branded 
prescription drugs, the requirement that manufacturers participate in a discount program for certain outpatient drugs under Medicare 
Part D and the expansion of the number of hospitals eligible for discounts under Section 340B of the PHSA. Additionally, the Inflation 
Reduction Act of 2022 includes several provisions such as drug pricing controls and Medicare redesign that are likely to impact our 
business to varying degrees, but its ultimate effect on our business and the healthcare industry in general is not yet known. See 
“Business-Government Regulation-Current and future healthcare reform legislation.”
We may face uncertainties due to efforts to repeal, substantially modify or invalidate some or all of the provisions of the ACA. There 
is no assurance that the ACA, as currently enacted or as amended in the future, will not adversely affect our business and financial 
results, and we cannot predict how future federal or state legislative or administrative changes relating to healthcare reform will affect 
our business.
There is increasing public attention on the costs of prescription drugs and there have been, and are expected to continue to be, 
legislative proposals to address prescription drug pricing, which could have significant effects on our business. These actions and the 
uncertainty about the future of the ACA and healthcare laws may put downward pressure on pharmaceutical pricing and increase our 
regulatory burdens and operating costs.
There is also significant economic pressure on state budgets that may result in states increasingly seeking to achieve budget savings 
through mechanisms that limit coverage or payment for drugs or that would allow for importation of pharmaceutical products from 
lower cost jurisdictions outside the United States. State Medicaid programs are increasingly requesting manufacturers to pay 
supplemental rebates and requiring prior authorization by the state program for use of any drug for which supplemental rebates are not 
being paid. Government efforts to reduce Medicaid expenses may lead to increased use of managed care organizations by Medicaid 
programs. This may result in managed care organizations influencing prescription decisions for a larger segment of the population and 
a corresponding limitation on prices and reimbursement for our products, if approved.
In the EU and some other international markets, the government provides health care at low cost to consumers and regulates 
pharmaceutical prices, patient eligibility or reimbursement levels to control costs for the government-sponsored health care system. 
Many countries have announced or implemented measures, and may in the future implement new or additional measures, to reduce 
health care costs to limit the overall level of government expenditures. These measures vary by country and may include, among other 
things, patient access restrictions, suspensions on price increases, prospective and possible retroactive price reductions and other 
recoupments and increased mandatory discounts or rebates, recoveries of past price increases and greater importation of drugs from 
lower-cost countries. These measures may adversely affect our revenues and results of operations.
We are subject, directly or indirectly, to federal and state healthcare fraud and abuse laws and false claims laws. If we cannot 
comply, or have not fully complied, with such laws, we could face substantial penalties.
Healthcare providers, physicians and third-party payors in the United States and elsewhere play a primary role in the recommendation 
and prescription of pharmaceutical products. Arrangements with third-party payors and customers can expose pharmaceutical 
70

manufacturers to broadly applicable fraud and abuse and other healthcare laws and regulations, which may constrain the business or 
financial arrangements and relationships through which such companies sell, market and distribute pharmaceutical products. In 
particular, the promotion, sales and marketing of healthcare items and services, as well as a wide range of pricing, discounting, 
marketing and promotion, structuring and commission(s), certain customer incentive programs and other business arrangements, are 
subject to extensive laws designed to prevent fraud, kickbacks, self-dealing and other abusive practices. These laws and regulations 
may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, structuring and commissions, certain customer 
incentive programs and other business arrangements generally. Activities subject to these laws also involve the improper use of 
information obtained during patient recruitment for clinical trials. See “Business-Government Regulation-Other healthcare laws.”
The scope and enforcement of each of these laws is uncertain and subject to rapid change in the current environment of healthcare 
reform, especially in light of the lack of applicable precedent and regulations. Ensuring business arrangements comply with applicable 
healthcare laws, as well as responding to possible investigations by government authorities, is time- and resource-consuming and can 
divert a company’s attention from the business. If our operations are found to violate any of these laws or any other regulations, we 
may be subject to significant sanctions, including civil, criminal and administrative penalties, damages, fines, disgorgement, 
imprisonment, reputational harm, exclusion from participation in federal and state funded healthcare programs, contractual damages 
and the curtailment or restricting of our operations, as well as additional reporting obligations and oversight if we become subject to a 
corporate integrity agreement or other agreement to resolve allegations of non-compliance. Furthermore, if any physician or other 
healthcare provider or entity with whom we do business is found to be not in compliance with applicable laws, they may be subject to 
similar penalties. Any action for violation of these laws, even if successfully defended, could cause us to incur significant legal 
expenses and divert management’s attention from the operation of the business. In addition, the approval and commercialization of 
any product candidate we develop outside the United States will subject us to foreign healthcare laws.
The provision of benefits or advantages to physicians to induce or encourage the prescription, recommendation, endorsement, 
purchase, supply, order or use of medicinal products is prohibited in the EU and the UK. The provision of benefits or advantages to 
induce or reward improper performance generally is also governed by the national anti-bribery laws of EU Member States, and the 
Bribery Act 2010 in the UK. Infringement of these laws could result in substantial fines and imprisonment. The EU Directive 
(2001/83/EC, as amended) governing medicinal products for human use provides that, where medicinal products are being promoted 
to persons qualified to prescribe or supply them, no gifts, pecuniary advantages or benefits in kind may be supplied, offered or 
promised to such persons unless they are inexpensive and relevant to the practice of medicine or pharmacy. This provision has been 
transposed into the Human Medicines Regulations 2012 and so remains applicable in the UK despite its departure from the EU.
Payments made to physicians in certain EU Member States must be publicly disclosed. Moreover, agreements with physicians often 
are the subject of prior notification and approval by the physician’s employer, his or her competent professional organization, or the 
regulatory authorities of the individual EU Member States. These requirements are provided in the national laws, industry codes or 
professional codes of conduct, applicable in the EU Member States. Failure to comply with these requirements could result in 
reputational risk, public reprimands, administrative penalties, fines or imprisonment.
We are subject to various and evolving laws and regulations governing the privacy and security of personal data, and our failure to 
comply could result in fines or criminal penalties and damage our reputation.
Privacy and data security are significant issues in the United States, Europe and many other jurisdictions where we operate or collect 
personal information. We are subject to data privacy and security laws and regulations in various jurisdictions that apply to the 
collection, storage, use, sharing and security of personal data, including health information, and impose significant compliance 
obligations. In addition, numerous other federal and state laws, including state security breach notification laws, state health 
information privacy laws and federal and state consumer protection and privacy laws, govern the collection, use, disclosure and 
security of personal information.
The GDPR and UK GDPR impose stringent obligations on us with respect to our processing and the cross-border transfer of personal 
data, including higher standards of obtaining consent or ensuring another appropriate legal basis or condition applies to the processing 
of personal data, more robust transparency requirements, data breach notification requirements, requirements for contractual language 
with our processors and stronger individual data rights. Different EEA Member States have interpreted the GDPR differently and 
many have imposed additional requirements, adding to the complexity of processing personal data in the EEA. The GDPR and UK 
GDPR also impose strict rules on the transfer of personal data to countries outside the EEA that are not considered to provide 
“adequate” protection to personal data, including the United States, and permits data protection authorities to impose large penalties 
for violations. Compliance with the GDPR and UK GDPR is a rigorous and time-intensive process that may increase our cost of doing 
business or require us to change our business practices. We could be subject to fines and penalties, litigation and reputational harm in 
connection with any activities falling within the scope of the GDPR or UK GDPR.
In the United States, at the federal level, failing to take appropriate steps to keep consumers’ personal information secure may 
constitute unfair acts or practices in or affecting commerce in violation of Section 5(a) of the Federal Trade Commission Act. In 
71

addition, certain state laws govern privacy and security of personal information. For example, California has passed the CCPA and 
numerous other states have passed their own similar comprehensive consumer privacy laws. There are also states that are specifically 
regulating health information. Further, a small number of states have passed laws that regulate biometric data specifically. In addition, 
numerous states and the federal government are actively considering proposed legislation governing the protection of personal data. 
State laws are changing rapidly and there have been discussions in the U.S. Congress of new comprehensive federal data privacy laws 
to which we could become subject, if enacted. 
Additionally, many foreign jurisdictions have passed data privacy legislation and others are considering various proposals for new 
privacy and data protection laws. Data privacy remains an evolving landscape at the domestic and international levels, with new laws 
and regulations being considered and coming into effect and continued legal challenges. We must devote significant resources to 
understanding and complying with the changing landscape in this area. Each law is also subject to various interpretations by courts 
and regulatory agencies, creating additional uncertainty, and any failure or perceived failure to comply with the evolving data 
protection laws could expose us to risk of enforcement actions taken by authorities, private rights of action in some jurisdictions and 
potential significant penalties if we are found to be non-compliant. Some of these laws and regulations also carry the possibility of 
criminal sanctions. For example, we could be subject to penalties, including criminal penalties, if we knowingly obtain or disclose 
individually identifiable health information from a HIPAA-covered health care provider or research institution that has not complied 
with HIPAA’s requirements for disclosing such information. Furthermore, the number of government investigations related to data 
security incidents and privacy violations continues to increase and government investigations typically require significant resources 
and generate negative publicity, which could harm our business and our reputation.
The Clinical Trials Regulation (EU) No. 536/2014 (the Clinical Trial Regulation) and the EMA policy on publication of clinical data 
for medicinal products for human use both permit the EMA to publish clinical information submitted in marketing authorization 
approvals (MAAs). The ability of third parties to review or analyze data from our clinical trials may increase the risk of commercial 
confidentiality breaches and result in enhanced scrutiny of our clinical trial results. Such scrutiny could result in public misconceptions 
regarding our drugs and drug candidates. These publications could also result in the disclosure of information to our competitors that 
we might otherwise deem confidential, which could harm our business.
Our use of GenAI and other AI technologies presents certain risks and challenges given the emerging nature of AI technologies.
The development and use of GenAI and other AI technologies (collectively, AI Technologies), along with an uncertain regulatory 
landscape, pose risks that could harm our reputation, expose us to liability or otherwise adversely affect our business. The integration 
of AI Technologies into our and our vendors’ systems (potentially without the vendor disclosing such use to us) subjects us to the risk 
that the providers of AI Technologies may not meet existing or rapidly evolving regulatory or industry standards with respect to 
privacy and data protection. Further, bad actors around the world use increasingly sophisticated methods, including the use of AI 
technologies, to engage in illegal activities involving the theft and misuse of personal information, confidential information and 
intellectual property. These factors may lead to breaches of security or privacy, reduced levels of service or experience, loss of 
intellectual property or exposure of confidential or proprietary information. Sophisticated cyber-attacks, including those using AI, 
could exacerbate these risks. Additionally, GenAI’s potential for producing false or misleading outputs, reflecting biases or generating 
content that may not be subject to IP protection or that infringes proprietary rights of others, poses additional risks to our business. 
Regulatory changes or reinterpretations could introduce new compliance risks, including potential government enforcement actions or 
civil lawsuits. Our competitors’ faster or more effective adoption of AI could also disadvantage us.
We could be adversely affected by outbreaks of epidemic, pandemic or other contagious diseases. 
In the event of a future epidemic or pandemic, our clinical trials could be paused or delayed due to restrictions (such as quarantines or 
travel limitations) or reprioritization of resources. Travel limitations could also create challenges and potential delays in our 
development and production activities, increasing the expense and timelines for producing our products and product candidates.
We utilize third parties to, among other things, manufacture raw materials, components, parts and consumables, perform quality 
testing and ship our products. If these third parties were to experience delays or disruptions in providing their services in response to 
an epidemic or pandemic, our supply chain could be disrupted, limiting our ability to manufacture and sell our products and 
manufacture product candidates for our clinical trials, as well as negatively impacting our research and development operations. Such 
delays or disruptions could adversely impact our strategic collaborators’ ability to fulfill their obligations, which could affect the 
clinical development or regulatory approvals of product candidates under joint development.
In addition, during a global health crisis, one or more government entities could take actions (such as via the Defense Production Act 
in the U.S.) that diminish our rights or economic opportunities with respect to our products. Our third-party service providers could be 
impacted by government-imposed restrictions on services they might otherwise offer. Any such action could cause us to experience 
delays in the development, production, distribution or export of our products and product candidates and increased expenses. 
72

Engaging in acquisitions, joint ventures or strategic collaborations may increase our capital requirements, dilute our shareholders 
and cause us to incur debt or assume contingent liabilities.
We may engage in acquisitions, joint ventures and collaborations, including licensing or acquiring complementary products, IP rights, 
technologies or businesses. Such transactions and relationships may entail numerous risks, including:
•
increased operating expenses and cash requirements;
•
assimilation of operations, IP and products, including difficulties associated with integrating new personnel;
•
the diversion of management’s attention from our existing product programs and initiatives;
•
the loss of key personnel and uncertainties in our ability to maintain key business relationships;
•
risks and uncertainties associated with the other party to such a transaction, including the prospects of that party and their 
existing products or product candidates and regulatory approvals; and
•
our inability to generate revenue from acquired technology or products sufficient to meet our objectives in undertaking the 
acquisition or even to offset the associated acquisition and maintenance costs.
If we undertake acquisitions in the future, we may utilize cash, issue dilutive securities, assume or incur debt obligations, incur large 
one-time expenses and acquire intangible assets that could result in significant future amortization expense. Moreover, if we cannot 
locate suitable acquisition or strategic collaboration opportunities, our ability to grow or obtain access to technology or products that 
may be important to the development of our business may be impaired.
The illegal distribution and sale by third parties of counterfeit or stolen versions of mRNA products could negatively impact our 
financial performance or reputation.
Third parties could illegally distribute and sell, especially online, counterfeit versions of mRNA products that do not meet the rigorous 
cGMP manufacturing and testing standards. Counterfeit medicines may contain harmful substances or the wrong dose, are frequently 
unsafe or ineffective and could be life-threatening. However, to distributors and users, counterfeit products may be visually 
indistinguishable from the authentic version.
Reports of adverse reactions to counterfeit products, increased levels of counterfeiting or unsafe mRNA products could materially 
affect patient confidence in our mRNA products. Adverse events caused by unsafe counterfeit or other non-mRNA products could 
mistakenly be attributed to our mRNA products. In addition, thefts of inventory at warehouses, plants or while in-transit, which are not 
properly stored and which are sold through unauthorized channels, could adversely impact patient safety, our reputation and our 
business. The public could lose confidence in the integrity of mRNA products because of counterfeiting, theft or improper 
manufacturing processes. 
Climate change or legal, regulatory or market measures to address climate change may negatively affect our business, results of 
operations and financial condition.
We are exposed to physical risks (such as rising temperatures, flooding and severe storms), risks in transitioning to a low-carbon 
economy (such as additional legal or regulatory requirements, changes in customer behavior and cost and availability of raw materials) 
and social and human effects (such as population dislocations and harm to health and well-being) associated with climate change. 
These risks can be either acute (short-term) or chronic (long-term). Climate-related physical risks to our facilities and those of our 
suppliers could disrupt our operations and supply chain, which may result in increased costs.
New legal or regulatory requirements may be enacted to prevent, mitigate or adapt to the implications of a changing climate and its 
effects on the environment. These regulations, which may differ across jurisdictions, could subject us to new or expanded carbon 
pricing or taxes, increased compliance costs, restrictions on greenhouse gas emissions, investment in new technologies, increased 
carbon disclosure and transparency, investments in data gathering and reporting systems, upgrades of facilities to meet new building 
codes and the redesign of utility systems, which could increase our operating costs, including the cost of electricity and energy we use. 
Our supply chain would likely be subject to these same transitional risks and would likely pass along any increased costs to us, which 
may affect our ability to procure raw materials or other supplies required to operate our business at the quantities and levels we 
require.
Our aspirations, goals and disclosures related to environmental, social and governance (ESG) matters expose us to numerous 
risks.
Many institutional and individual investors use ESG screening criteria to determine whether we qualify for inclusion in their 
investment portfolios. We are frequently asked by investors and other stakeholders to set ESG goals and provide new and more robust 
disclosure on goals, progress toward goals and other matters of interest to ESG stakeholders. In response, we have adapted the 
tracking and reporting of our corporate responsibility program to various evolving ESG frameworks, and we have established and 
73

announced goals and other objectives related to ESG matters. Statements about these goals reflect our current plans and aspirations 
and are not guarantees that we will be able to achieve them. Our efforts to accomplish and accurately report on these goals and 
objectives, including with respect to environmental and diversity initiatives, are subject to numerous risks, many of which are outside 
of our control, which could have a material negative impact, including on our reputation and stock price. Additionally, the increased 
focus on ESG matters by policymakers, regulators and investors has in some instances resulted in diverging expectations and 
standards, which could make it more difficult to comply with ESG-related regulations across our global business. 
Further, the standards for tracking and reporting on ESG matters are relatively new, have not been harmonized and continue to evolve. 
Our selection of disclosure frameworks that seek to align with various reporting standards may change from time to time and may 
result in a lack of consistent or meaningful comparative data from period to period. In addition, our processes and controls may not 
always comply with evolving standards for identifying, measuring and reporting ESG metrics, our interpretation of reporting standards 
may differ from those of others and such standards may change over time, any of which could result in significant revisions to our 
goals or reported progress in achieving such goals.
If our ESG practices do not meet evolving investor or other stakeholder expectations and standards, then our reputation, our ability to 
attract or retain employees and our attractiveness as an investment, business partner or acquiror could be negatively impacted. 
Similarly, our failure or perceived failure to pursue or fulfill our goals, targets and objectives or to satisfy various reporting standards 
within the timelines we announce, or at all, could also have similar negative impacts and expose us to government enforcement actions 
and private litigation.
If we fail to comply with environmental, health and safety laws and regulations, we could become subject to fines or penalties or 
incur costs that could harm our business.
We are subject to numerous environmental, health and safety laws and regulations, including those governing laboratory procedures 
and the handling, use, storage, treatment and disposal of hazardous and flammable materials and wastes, including chemicals and 
biological materials. We generally contract with third parties for the disposal of these materials and waste products, and we cannot 
eliminate the risk of contamination or injury from these materials. In the event of contamination or injury resulting from any use by us 
of hazardous materials, we could be held liable for any resulting damages, and any liability could exceed our resources. We also could 
incur significant costs associated with civil or criminal fines, penalties or other sanctions for failure to comply with such laws and 
regulations. We may also incur substantial costs to comply with such laws and regulations, and these laws and regulations could 
impair our research, development or production efforts.
Our workers’ compensation insurance may not provide adequate coverage against potential liabilities due to injuries to our employees 
resulting from the use of hazardous materials. We do not maintain insurance for environmental liability or toxic tort claims that may 
be asserted against us in connection with our storage or disposal of biological or hazardous materials.
Risks related to ownership of our common stock
The price of our common stock has been volatile, which could result in substantial losses for shareholders.
Our stock price has been, and is expected to continue to be, subject to substantial volatility. Since our IPO in December 2018, our 
stock price has ranged from a high of $497.49 to a low of $11.54 per share. Over the last several years, our stock has experienced 
pronounced and extended periods of volatility, which could cause our shareholders to incur substantial losses. Public statements by us, 
government agencies, the media, competitors, financial analysts or others, including those related to COVID-19, have resulted, and 
may result, in significant fluctuations in our stock price. Information in the public arena, whether or not accurate, has had and will 
likely continue to have an outsized impact (positive or negative) on our stock price. 
The stock market in general, and the market for biopharmaceutical companies in particular, has experienced extreme volatility that has 
often been unrelated to the operating performance of particular companies, and you may not be able to sell your shares at or above 
your initial purchase price. The market price for our common stock may be influenced by many factors, including:
•
our product sales and anticipated product revenue;
•
our ability to effectively reduce costs;
•
the commercial launch of any additional products;
•
timing and results of clinical trials or progress of our product candidates or those of our competitors;
•
the exclusion or removal of our stock from market indices; 
•
the success of competitive products or technologies;
•
the emergence or decline of new or existing variants of the SARS-CoV-2 virus;
•
developments regarding our manufacturing, regulatory and commercialization efforts, or information regarding such efforts 
by competitors;
74

•
regulatory or legal developments in the United States and other countries;
•
developments or disputes concerning patent applications, issued patents or other proprietary rights;
•
the recruitment or departure of key personnel;
•
expenses related to any of our products or clinical development programs;
•
the results of our efforts to discover, develop, acquire or in-license additional product candidates;
•
actual or anticipated changes in estimates of financial results, development timelines or recommendations by securities 
analysts;
•
variations in our financial results or those of companies that are perceived to be similar to us;
•
changes in the structure of healthcare payment systems;
•
economic, industry and market conditions generally, and in the biopharmaceutical sector specifically; and
•
announcement by us or our competitors of the commencement or termination of significant acquisitions, strategic 
partnerships, joint ventures or capital commitments.
Securities class-action litigation often has been instituted against companies following periods of volatility in their stock price. In 
2024, class action and derivative litigations were filed against us related to statements made about our RSV vaccine. See Item 3. 
“Legal Proceedings.” We could incur substantial costs in defense of such litigation, or in defense of any future lawsuits that may be 
filed against us, and management’s attention and resources could be diverted.
Our principal shareholders and management own a significant percentage of our stock and will be able to exert significant control 
over matters subject to shareholder approval.
As of February 14, 2025, our executive officers, directors and affiliated shareholders owned, directly or indirectly, approximately 8% 
of our outstanding common stock. In addition, non-affiliated five percent or greater shareholders owned approximately 27% of our 
outstanding common stock. These shareholders will have the ability to influence us through their ownership positions. For example, if 
they were to act together, they could exert significant influence over matters such as elections of directors, amendments of our 
organizational documents or approval of any merger, sale of assets or other major corporate transaction. This may prevent or 
discourage unsolicited acquisition proposals or offers for our common stock that our shareholders may believe to be in their best 
interests.
Provisions in our organizational documents, as well as provisions of Delaware law, could make it more difficult or costly for a 
third party to acquire us or remove our current management, even if doing so would benefit our shareholders.
Our restated certificate of incorporation (charter), second amended and restated by-laws (by-laws) and Delaware law contain 
provisions that could delay or prevent a hostile takeover or change in control of us or changes in our management. Our charter and by-
laws include provisions that:
•
authorize “blank check” preferred stock, which could be authorized for issuance by our board of directors without 
shareholder approval and may contain voting, liquidation, dividend and other rights superior to our common stock;
•
create a classified board of directors whose members serve staggered three-year terms;
•
limit shareholders’ ability to call a special meeting of shareholders to shareholders representing at least 20% of our 
outstanding shares;
•
prohibit shareholder action by written consent;
•
establish an advance notice procedure for shareholder approvals to be brought before an annual meeting of our shareholders, 
including proposed nominations of persons for election to our board of directors;
•
provide that our directors may be removed only for cause;
•
provide that vacancies on our board of directors may be filled only by a majority of directors then in office, even though less 
than a quorum;
•
specify that no shareholder is permitted to cumulate votes at any election of directors;
•
expressly authorize our board of directors to modify, alter or repeal our by-laws; and
•
require supermajority votes of the holders of our common stock to amend specified provisions of our charter and by-laws.
In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General 
Corporation Law, which limits the ability of shareholders owning in excess of 15% of our outstanding voting stock to merge or 
combine with us. Any provision of our charter, by-laws or Delaware law that has the effect of delaying or deterring a change in control 
could limit the opportunity for our shareholders to receive a premium for their shares, and could also affect the price that some 
investors are willing to pay for our common stock.
75

Because we do not anticipate paying any cash dividends on our capital stock in the foreseeable future, capital appreciation, if any, 
will be your sole source of gain.
We do not currently intend to declare or pay cash dividends on our capital stock. We currently intend to retain all of our future 
earnings, if any, to finance the growth and development of our business or to return cash to shareholders through share repurchases. In 
addition, the terms of any future debt agreements may preclude us from paying dividends. As a result, capital appreciation, if any, of 
our common stock will be your sole source of gain for the foreseeable future.
Our by-laws designate the Court of Chancery of the State of Delaware or the U.S. District Court for the District of Massachusetts 
as the exclusive forum for certain litigation that may be initiated by our shareholders, which could limit our shareholders’ ability 
to obtain a favorable judicial forum for disputes with us.
Pursuant to by-laws, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of 
Delaware is the sole and exclusive forum for state law claims for (1) any derivative action or proceeding brought on our behalf, (2) 
any action asserting a claim of or based on a breach of a fiduciary duty owed by any of our current or former directors, officers, or 
other employees to us or our shareholders, (3) any action asserting a claim against us or any of our current or former directors, 
officers, employees or shareholders arising pursuant to any provision of the Delaware General Corporation Law or our by-laws or (4) 
any action asserting a claim governed by the internal affairs doctrine (the Delaware Forum Provision). The Delaware Forum Provision 
will not apply to any causes of action arising under the Securities Act or the Exchange Act. Our by-laws further provide that the U.S. 
District Court for the District of Massachusetts is the exclusive forum for resolving any complaint asserting a cause of action arising 
under the Securities Act (the Federal Forum Provision). Our by-laws provide that any person or entity purchasing or otherwise 
acquiring any interest in shares of our common stock is deemed to have notice of and consented to the Delaware Forum Provision and 
the Federal Forum Provision. 
The Delaware Forum Provision and the Federal Forum Provision may impose additional litigation costs on shareholders in pursuing 
any such claims, particularly if the shareholders do not reside in or near the State of Delaware or the Commonwealth of 
Massachusetts, as applicable. Additionally, the forum selection clauses in our by-laws may limit our shareholders’ ability to obtain a 
favorable judicial forum for disputes with us or our directors, officers or employees, which may discourage the filing of lawsuits 
against us and our directors, officers and employees, even though an action, if successful, might benefit our shareholders. The Federal 
Forum Provision may also impose additional litigation costs on shareholders who assert that the provision is unenforceable or invalid, 
and if the Federal Forum Provision is found to be unenforceable, we may incur additional costs in resolving such matters. The Court 
of Chancery of the State of Delaware and the U.S. District Court for the District of Massachusetts may also reach different judgments 
or results than would other courts, including courts where a shareholder considering an action may be located or would otherwise 
choose to bring the action, and such judgments may be more or less favorable to us than our shareholders.
General risk factors
Our employees, principal investigators and consultants may engage in misconduct or other improper activities, including non-
compliance with regulatory standards and requirements and insider trading.
We are exposed to the risk of fraud or other misconduct by our employees, principal investigators leading our clinical trials and 
consultants. Such misconduct could include failures to comply with FDA regulations or similar regulations in other jurisdictions, 
provide accurate information to the FDA, the EMA and other regulatory authorities, comply with healthcare fraud and abuse laws and 
regulations in the United States and abroad, comply with industry codes of conduct, report financial information or data accurately, or 
disclose unauthorized activities to us. Such misconduct also could involve improper use of information obtained during clinical trials 
or interactions with the FDA or other regulatory authorities, which could result in regulatory sanctions and serious harm to our 
reputation. Sales, marketing and business arrangements in the healthcare industry are subject to extensive laws and regulations 
intended to prevent fraud, misconduct, kickbacks, self-dealing and other abusive practices. These laws and regulations restrict or 
prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, customer incentive programs and other 
business arrangements. It is not always possible to identify and deter employee misconduct, and we may fail to control unknown or 
unmanaged risks or losses or take steps that protect us from government investigations or other actions or lawsuits stemming from a 
failure to comply with these laws or regulations. If any such actions are instituted against us, those actions could have a significant 
impact on our business, financial condition, results of operations and prospects, including through the imposition of significant fines or 
other sanctions.
We could face unfavorable U.S. or global economic conditions, including as a result of disease outbreak, war, conflict or other 
political instability, or geopolitical risks.
Our results of operations could be adversely affected by general conditions in the global economy and financial markets, including 
disruptions caused by pandemic, war, conflict or other political instability, including related to Russia’s invasion of Ukraine and 
76

resulting sanctions against Russia or conflict in the Middle East. Adverse macroeconomic conditions, and perceptions or expectations 
about current or future conditions, such as inflation, slowing growth, rising interest rates, the imposition of tariffs (either on imports or 
exports, which may impact us directly or indirectly through increased costs in our supply chain), rising unemployment and recession, 
could negatively affect our business and financial condition. Additionally, global events, including war, conflict, political instability or 
other adverse economic conditions have and may in the future cause governments to divert spending away from healthcare, negatively 
impacting the market for our products.
Any severe or prolonged economic downturn could create a variety of risks to our business, including weakened demand for our 
medicines, and negatively impact our ability to raise additional capital or financing if needed on favorable terms, if at all. A weak or 
declining economy could strain our suppliers, possibly resulting in supply disruption, or cause delays in payments for our services by 
third-party payors or our collaborators. Any of the foregoing could harm our business and we cannot anticipate all the ways in which 
the current economic climate and financial market conditions could adversely impact our business.
Additionally, geopolitical tensions could adversely impact our business and our commercial plans. For instance, restrictions by the 
U.S. government on the export of mRNA technology or our products to certain markets, or restrictions on the establishment of 
manufacturing in certain foreign jurisdictions, may prevent us from seeking commercial growth opportunities in a manner that harms 
our competitive position.
Employee litigation and unfavorable publicity could negatively affect our future business.
Our employees may, from time to time, bring lawsuits against us regarding injury, creating a hostile workplace, discrimination, wage 
and hour disputes, sexual harassment or other employment issues. Recently, there has been an increase in the number of discrimination 
and harassment claims generally. Coupled with the expansion of social media platforms and similar devices that allow individuals 
access to a broad audience, these claims have had a significant negative impact on some businesses. Certain companies that have faced 
employment- or harassment-related lawsuits have had to terminate management or other key personnel, and have suffered reputational 
harm.
Ineffective internal controls could adversely impact our business and operating results.
Our internal control over financial reporting may not prevent or detect misstatements because of its inherent limitations, including the 
possibility of human error, failure or interruption of information technology systems, the circumvention or overriding of controls, or 
fraud. Even effective internal controls can provide only reasonable assurance with respect to the preparation and fair presentation of 
financial statements. If we fail to maintain the adequacy of our internal controls, including any failure to implement required new or 
improved controls, or if we experience difficulties in their implementation, our business and operating results could be harmed and we 
could fail to meet our financial reporting obligations.
Inadequate funding for the FDA, CDC and other government agencies, including from government shut downs, or other 
disruptions to these agencies’ operations, could hinder their ability to hire and retain key leadership and other personnel, prevent 
new products and services from being developed or commercialized in a timely manner or otherwise prevent those agencies from 
performing normal business functions on which the operation of our business may rely.
Currently, federal agencies in the U.S. are operating under a continuing resolution that is set to expire on March 14, 2025. Without 
appropriation of additional funding to federal agencies, our business operations related to our product development activities for the 
U.S. market could be impacted. The ability of the FDA to review and approve new products can be affected by a variety of factors, 
including government budget and funding levels, the ability to hire and retain key personnel and accept the payment of user fees, and 
statutory, regulatory and policy changes. Average review times at the agency have fluctuated in recent years as a result. In addition, 
government funding of other government agencies on which our operations may rely, including those that fund research and 
development activities, is subject to the political process, which is inherently fluid and unpredictable. Disruptions at the FDA, CDC 
and other agencies may also slow the time necessary for new product candidates to be reviewed or approved, or for recommendations 
on use to be developed. If a prolonged government shutdown occurred, it could significantly impact the ability of the FDA to timely 
review and process our regulatory submissions.
Changes in tax law could adversely affect our business and financial condition.
We are subject to evolving and complex tax laws in the jurisdictions in which we operate. The rules dealing with U.S. federal, state, 
local and non-U.S. income taxation are constantly under review by legislative and tax authorities. Changes to tax laws (which could 
apply retroactively) could adversely affect us and our shareholders. In recent years, such changes have been made and changes are 
likely to occur in the future, which could have a material adverse effect on our business, cash flow, financial condition and results of 
operations.
77

The increasing use of social media platforms presents risks and challenges.
Social media is increasingly being used to communicate about our research, product candidates, commercial products and the diseases 
our products and product candidates are designed to treat. Social media practices in the biopharmaceutical industry continue to evolve 
and regulations relating to such use are not always clear. This uncertainty creates risk of noncompliance with regulations applicable to 
our business, resulting in potential regulatory actions against us. For example, subjects may use social media channels to comment on 
their experience in an ongoing blinded clinical trial or to report an alleged adverse event. When such disclosures occur, we may fail to 
monitor and comply with applicable adverse event reporting obligations or we may be unable to defend our business in the face of 
political and market pressures generated by social media due to restrictions on what we may say about our product candidates. There is 
also a risk of inappropriate disclosure of sensitive information or negative or inaccurate posts or comments about us on any social 
networking website. If any of these events were to occur or we otherwise fail to comply with applicable regulations, we could incur 
liability, face regulatory actions or incur other harm to our business.
Item 1B. Unresolved Staff Comments
None.
Item 1C. Cybersecurity
Cyber Risk Management and Strategy                                 
Our cybersecurity organization’s mission is to provide a targeted set of services, support and capabilities to reduce the risk of 
cyberattacks, rapidly detect and contain threats, and mitigate risks to critical data.
Recognizing the threat of security breaches and cyberattacks globally, we have developed a cybersecurity program, overseen by our 
Chief Information Security Officer (CISO), that is designed to protect patient trust, defend the Moderna brand, and reduce the risk and 
impact of cyber-attacks. Our cybersecurity program is informed by industry standards and includes periodic risk assessments and 
security testing supported by cybersecurity technologies, including third-party security solutions, vulnerability management, and 
monitoring tools, designed to monitor, identify, and manage risks from cyber threats. In addition, we have implemented employee 
security and awareness training. 
Management has established a cyber incident response plan (CIRP) designed to assess, identify and manage risks from cybersecurity 
threats and enable prompt response in the event that a cybersecurity incident is detected. We have a process in place for notification to 
our leadership response team in the event of a significant cyber incident, and for escalation of these events to our Audit Committee 
and Board, as appropriate. To date, we have not experienced a cybersecurity incident that has had a material impact on our business 
strategy, results of operations, or financial condition.
We undergo several annual internal compliance audits and external reviews to evaluate our controls, including cybersecurity controls. 
In an effort to minimize third-party risk, we have established a process to assess the security practices of third-party suppliers and 
related risks, including through review of relevant supplier certifications and security and responses to standardized information 
gathering (SIG) questionnaires, as applicable and appropriate. 
Governance Related to Cybersecurity Risks
Our Board of Directors oversees Moderna’s overall risk management strategy. The Board exercises oversight of risks from 
cybersecurity threats primarily through its Audit Committee, which oversees our risk management processes for information security 
and technology risks. Our cybersecurity risk management processes are integrated into our overall risk management strategy, which is 
overseen by the Audit Committee. At least annually, the Audit Committee discusses our risk management program, including 
information security and technology risks and findings from any audits, with our internal audit staff. 
The Audit Committee receives cyber-related updates from management, including our CISO at committee meetings. During meetings, 
our CISO updates the committee on Moderna’s cybersecurity posture, potential threats and risk mitigation strategies, and the progress 
of the Company’s cybersecurity initiatives, as appropriate. The Chair of the Audit Committee and management provide regular 
briefings on such matters to the full Board of Directors, as appropriate. 
At the management level, our CISO is primarily responsible for leading our cybersecurity strategy for assessing and managing 
material risks from cybersecurity threats. Our current CISO has over 25 years of cybersecurity experience across a wide array of 
industries, most recently serving in leadership positions at two different public companies and previous roles of increasing 
responsibility at multinational technology companies. Our CISO reports directly to our Chief People and Digital Technology Officer, 
who is a member of our Executive Committee and reports to our Chief Executive Officer. 
78

We have built a cybersecurity leadership team designed to align with key services, with a separate lead overseeing each service 
offering, all reporting to the CISO. We also maintain relationships with law enforcement and industry groups to support our 
cybersecurity intelligence and risk management efforts.
Item 2. Properties
We have two main campuses in Massachusetts. During the third quarter of 2023, we commenced a lease for a property in Cambridge, 
Massachusetts. This building, spanning approximately 462,000 square feet, is designated as our Moderna Science Center (MSC). The 
MSC accommodates a combination of scientific and office spaces, including our principal executive offices. The lease has a term of 
15 years, with options for us to extend the lease for up to two additional seven-year terms. As of December 31, 2024, we have 
substantially exited our leased spaces at Technology Square in Cambridge, Massachusetts, completing the consolidation of our 
Cambridge operations into the MSC. The MSC campus is the location of our corporate headquarters, platform, drug discovery and 
clinical development. 
The Moderna Technology Center (MTC) is located in Norwood, Massachusetts and is primarily comprised of three buildings (MTC 
South, MTC North and MTC East). The MTC campus is approximately 722,000 square feet which includes lab and office space, 
directly supporting our manufacturing capabilities and commercial and clinical activities. In December 2024, we completed the 
acquisition of the MTC campus, including the underlying land and buildings. This acquisition transitioned the facilities from leased to 
owned properties, providing greater operational flexibility and long-term stability in supporting our manufacturing and development 
capabilities.
In the second quarter of 2023, we acquired a newly constructed biomanufacturing facility, encompassing 140,000 square feet, in 
Marlborough, Massachusetts. This facility is undergoing enhancements, including the addition of 60,000 square feet to the existing 
structure. Upon completion, the facility will have state-of-the-art mRNA manufacturing areas, including a full manufacturing clean 
room, quality control laboratories, and a just-in-time satellite warehouse. We expect the facility to be operational in 2025. This new 
site is strategically intended to support our INT program.
In September 2024, we completed our manufacturing facility in Laval, Quebec, Canada, which received a Drug Establishment License 
(DEL) from Health Canada. This certification enables the facility to produce drug substance and positions it to manufacture mRNA 
vaccines, including COVID, RSV, and seasonal influenza, contingent on Health Canada’s approval, starting in 2025. The site 
strengthens our global manufacturing capabilities and supports the Government of Canada’s pandemic readiness and vaccine supply 
objectives.
We also own and lease various parcels of land, office and lab spaces across the globe for our business operations.
Item 3. Legal Proceedings
We are involved in various claims and legal proceedings of a nature considered ordinary course in our business, including the 
intellectual property litigation described below. Most of the issues raised by these claims are highly complex and subject to substantial 
uncertainties. For a description of risks relating to these and other legal proceedings we face, see Part I, Item 1A, “Risk Factors,” 
including the discussion under the headings entitled “Risks related to our intellectual property” and “Risks related to the 
manufacturing of our commercial products and product candidates.” 
The outcome of any such proceedings, regardless of the merits, is inherently uncertain; therefore, assessing the likelihood of loss and 
any estimated damages is difficult and subject to considerable judgment. We describe below those legal matters for which a material 
loss is either (i) possible but not probable, and/or (ii) not reasonably estimable at this time.
Pfizer/BioNTech Patent Litigation
In August 2022, we filed a lawsuit in the U.S. District Court for the District of Massachusetts against Pfizer Inc. (Pfizer) and 
BioNTech SE, BioNTech Manufacturing GmbH and BioNTech US Inc. (collectively, BioNTech), asserting infringement of certain 
U.S. patents concerning our mRNA platform technology and disease-specific vaccine designs in Pfizer and BioNTech’s manufacture 
and sale of their mRNA COVID vaccines. The complaint seeks a judgment of infringement of the asserted patents and monetary 
damages. The case has been stayed pending the outcome of two Inter Partes Proceedings (IPRs) pending before the U.S. Patent and 
Trademark Office’s Patent Trial and Appeal Board (PTAB) regarding the validity of two of the three asserted patents in this lawsuit. 
The PTAB is expected to issue a decision on the IPRs on or before March 6, 2025, which would be subject to appeal. 
Also in August 2022, we initiated patent infringement proceedings in Germany (in the Dusseldorf Regional Court), the Netherlands 
(in the District Court of The Hague) and the UK (in the High Court of Justice of England & Wales) against Pfizer, BioNTech and 
79

related entities with respect to certain European patents that also concern our mRNA platform technology and disease-specific vaccine 
designs, including coronaviruses. In May 2023, we initiated patent infringement proceedings in Ireland (in the High Court) and 
Belgium (Brussels Business Court) against Pfizer, BioNTech and related entities with respect to the same European patents. As in the 
U.S. action, we seek a judgment of infringement of the asserted patents and monetary damages.
Pfizer Inc. and BioNTech SE have also filed an action seeking revocation of certain Moderna patents in the UK. In addition, the 
Moderna patents being asserted in the European actions are subject to notices of opposition, including by Pfizer and BioNTech SE and 
others. These actions seek to revoke the patents, which have been filed at the European Patent Office. There are two patents at issue in 
the European patent infringement proceedings–EP3590949 (the ‘949 patent), which relates to chemically-modified mRNA and 
EP3718565 (the ‘565 patent), which relates to coronavirus mRNA vaccines. In July 2024, the High Court of Justice of England & 
Wales issued a judgment confirming the validity of the ‘949 patent and finding that Pfizer and BioNTech had infringed the patent. The 
court further determined that the ‘565 patent was invalid. The High Court’s decision related to the ‘949 patent is subject to appeal. In 
December 2023, the District Court of The Hague issued a first instance decision determining that the ‘949 patent was invalid in the 
Netherlands. Moderna has appealed this decision to the Court of Appeal of The Hague, with a second instance decision expected in 
2025. In addition, there remain ongoing Opposition Proceedings at the European Patent Office by a number of opponents, including 
Pfizer and BioNTech related to these two patents.
Proceedings Related to Patents Owned by Arbutus
In February 2022, Arbutus Biopharma Corporation (Arbutus) and Genevant Sciences GmbH (Genevant) filed a complaint against us 
in the U.S. District Court for the District of Delaware asserting that our manufacture and sale of our COVID vaccine willfully 
infringes certain U.S. patents concerning lipid nanoparticles. The complaint seeks a judgment of infringement of the asserted patents 
and monetary damages, but does not seek to prevent or stop the marketing or sales of our COVID vaccines. The Court has set trial to 
begin September 24, 2025, subject to the Court’s availability.
Proceedings Related to Patents Owned by GSK
COVID-19 Vaccines
In October 2024, GlaxoSmithKline Biologicals SA (GSK) filed a complaint against us in the U.S. District Court for the District of 
Delaware asserting that our manufacture and sale of our COVID vaccines infringe certain U.S. patents directed to lipid-mRNA 
vaccine formulation technology. The complaint seeks a judgment of infringement of the asserted patents and unspecified damages, but 
does not seek injunctive relief.
RSV Vaccine
Also in October 2024, GSK filed a complaint against us in the U.S. District Court for the District of Delaware asserting that our 
manufacture and sale of our RSV vaccine infringes certain U.S. patents directed to lipid-mRNA vaccine formulation technology. The 
complaint seeks a judgment of infringement of the asserted patents, unspecified damages and injunctive relief in the United States.
Proceedings Related to Patents Owned by Northwestern University
In October 2024, Northwestern University filed a complaint against us in the U.S. District Court for the District of Delaware asserting 
that our COVID and RSV vaccines infringe several U.S. patents concerning lipid nanoparticle technology. The complaint seeks a 
judgment of infringement of the asserted patents and unspecified damages. The complaint does not seek injunctive relief.
Securities Class Action Litigation
In August 2024, a putative shareholder class action complaint was filed against the Company and certain officers in the U.S. District 
Court for the District of Massachusetts. The action is purportedly brought on behalf of a class of shareholders who purchased Moderna 
common stock between January 18, 2023 and June 25, 2024. The complaint asserts claims under the Securities Exchange Act of 1934 
regarding statements about our RSV vaccine (mRNA-1345) and seeks unspecified damages.
Derivative Litigation
Between September and November 2024, purported shareholder derivative complaints were filed in the U.S. District Court for the 
District of Massachusetts against certain of our officers and directors and against the Company as a nominal defendant. The 
complaints allege breaches of fiduciary duty and claims under the Securities Exchange Act of 1934 regarding statements about 
mRNA-1345 and seek declaratory and injunctive relief and unspecified damages payable to us.
80

Proceedings Related to Patents Owned by Alnylam
In March 2022 and July 2022, Alnylam Pharmaceuticals, Inc. (Alnylam) filed two complaints against us in the U.S. District Court for 
the District of Delaware asserting that our manufacture and sale of our COVID vaccine infringes certain U.S. patents concerning 
cationic lipids. On August 25, 2023, the Court entered a Final Judgment of non-infringement of all asserted patents in these lawsuits. 
Alnylam has appealed this judgment to the Federal Circuit Court of Appeals. 
In May 2023, Alnylam filed a third complaint against us in the U.S. District Court for the District of Delaware asserting three 
additional U.S. patents concerning cationic lipids. The complaints seek judgments of infringement of the asserted patents and 
monetary damages, but do not seek to prevent or stop the marketing or sales of our COVID vaccines. In November 2023, the District 
Court entered an order of partial dismissal with respect to two of the patents at issue. Subsequently, in October 2024, the District Court 
entered a final judgment of non-infringement in our favor with respect to the third patent at issue. The decision is subject to appeal.

risks and uncertainties. As a result of many factors, including those factors set forth in “Part I, Item 1A - Risk Factors” section of this 
Annual Report on Form 10-K, our actual results could differ materially from the results described in or implied by the forward-
looking statements contained in the following discussion and analysis.
Overview 
We are a biotechnology company advancing a new class of medicines made of messenger RNA (mRNA). mRNA medicines are 
designed to direct the body’s cells to produce intracellular, membrane or secreted proteins that have a therapeutic or preventive benefit 
with the potential to address a broad spectrum of diseases. Our platform builds on continuous advances in basic and applied mRNA 
science, delivery technology and manufacturing, providing us the capability to pursue in parallel a robust pipeline of new development 
candidates. We are developing medicines across four franchises: respiratory virus vaccines, latent and other virus vaccines, oncology 
therapeutics and rare disease therapeutics.
Since our founding in 2010, we have transformed from a research-stage company advancing programs in the field of mRNA to a 
commercial enterprise with a diverse clinical portfolio of vaccines and therapeutics across several modalities, a broad intellectual 
property portfolio and integrated manufacturing capabilities that allow for rapid clinical and commercial production at scale. We have 
a diverse and extensive development pipeline of 34 development candidates across our 44 development programs, of which 41 are in 
clinical studies currently.
Our COVID vaccine is our first commercial product and is marketed, where approved, under the name Spikevax®. Our original 
vaccine, mRNA-1273, targeted the SARS-CoV-2 ancestral strain, and we have leveraged our mRNA platform to rapidly adapt our 
vaccine to emerging SARS-CoV-2 strains to provide protection as the virus evolves and regulatory guidance is updated. In May 2024, 
the U.S. Food and Drug Administration (FDA) granted approval for mRESVIA® (mRNA-1345), our mRNA vaccine against 
respiratory syncytial virus (RSV), to protect adults aged 60 and older from lower respiratory tract disease caused by RSV infection. 
This marks our second approved mRNA product and underscores our ongoing commitment to delivering solutions for patients by 
addressing global public health threats related to infectious diseases.
2024 Business Highlights 
Respiratory Vaccines
During the fourth quarter of 2024, we achieved significant milestones in our respiratory vaccine portfolio. We filed for regulatory 
approval with the FDA for our next-generation COVID vaccine (mRNA-1283), supported by positive Phase 3 efficacy and 
immunogenicity data, leveraging a priority review voucher, and have been assigned a Prescription Drug User Fee Act (PDUFA) goal 
date of May 31, 2025. We also submitted a regulatory application for our respiratory syncytial virus (RSV) vaccine, mRESVIA 
(mRNA-1345), for high-risk adults aged 18 to 59, following positive Phase 3 data and using a priority review voucher, and have been 
assigned a PDUFA goal date of June 12, 2025. Additionally, we filed for FDA approval of our flu+COVID combination vaccine 
(mRNA-1083), based on positive Phase 3 immunogenicity data in adults aged 50 years and older.
Net Product Sales and Net (Loss) Earnings Per Share
For the year ended December 31, 2024, we recognized net product sales of $3.1 billion from sales of our COVID and RSV vaccines, 
compared to $6.7 billion and $18.4 billion for the years ended December 31, 2023 and 2022, respectively. Loss per share was $(9.28) 
for the year ended December 31, 2024, compared to (loss) earnings per share of $(12.33) and $20.12 for the years ended December 31, 
2023 and 2022, respectively.
Program Developments 
As of December 31, 2024, eleven of our 44 development programs are in late-stage development, including nine programs in Phase 3 
and two rare disease programs that are expected to generate pivotal data in 2025.

Respiratory Vaccines
•
Next-generation COVID vaccine: We shared positive Phase 3 vaccine efficacy and immunogenicity data for our next-
generation COVID vaccine (mRNA-1283) at our 2024 R&D Day event in September 2024. We have filed for regulatory 
approval of mRNA-1283 with the FDA using a priority review voucher. The FDA has accepted our Biologics License 
Application (BLA) for mRNA-1283 and has assigned a PDUFA goal date of May 31, 2025.
•
RSV vaccine: We received regulatory approval of our RSV vaccine mRESVIA (mRNA-1345) for adults aged 60 years and 
older in 2024. We shared positive Phase 3 data for mRNA-1345 in high-risk adults aged 18 to 59 at our 2024 R&D Day event 
and have since submitted an application to the FDA for regulatory approval using a priority review voucher, and have been 
assigned a PDUFA goal date of June 12, 2025.
•
Seasonal flu + COVID vaccine: We shared positive Phase 3 immunogenicity data for our flu+COVID combination vaccine 
(mRNA-1083) for adults aged 50 years and older at our 2024 R&D Day event. We have filed with the FDA for regulatory 
approval of mRNA-1083, which may require vaccine efficacy data from our ongoing Phase 3 seasonal flu vaccine study.
•
Seasonal flu vaccine: We have shared positive Phase 3 immunogenicity and safety data for our seasonal flu vaccine 
(mRNA-1010). We are conducting a two-season Phase 3 efficacy study (P304), where the timing of the efficacy readout 
depends on case accrual and could happen in the current season. 
Latent and Other Vaccines
•
Cytomegalovirus (CMV) vaccine: The pivotal Phase 3 study of our CMV vaccine candidate (mRNA-1647) is fully enrolled 
and accruing cases, evaluating its efficacy, safety and immunogenicity in the prevention of primary infection in women of 
childbearing age. The Data Safety Monitoring Board (DSMB) met to review the initial study data and has informed us that 
the criterion for early efficacy was not met. The DSMB recommended that the study continue as planned. We remain blinded 
and anticipate final efficacy data from the study in 2025.
•
Norovirus vaccine: The two-season Phase 3 study evaluating the efficacy, safety and immunogenicity of our trivalent vaccine 
candidate against norovirus (mRNA-1403) is fully enrolled in the Northern Hemisphere and we are preparing second season 
enrollment in the Southern Hemisphere. The trial is currently on FDA clinical hold following a single adverse event report of 
Guillain-Barré syndrome, which is currently under investigation. We do not expect an impact on the study's efficacy readout 
timeline as enrollment in the Northern Hemisphere has already been completed. The timing of the Phase 3 readout will be 
dependent on case accruals.
Oncology Therapeutics 
•
Individualized Neoantigen Therapy (INT): We continue to demonstrate the potential clinical benefit of our INT 
(mRNA-4157). In collaboration with Merck, the Phase 3 clinical trial for adjuvant melanoma is fully enrolled. Two Phase 3 
studies for non-small cell lung cancer are enrolling. A randomized Phase 2 study for high-risk muscle invasive bladder cancer 
is enrolling, and a randomized Phase 2 study for adjuvant renal cell carcinoma is enrolling.
Rare Diseases
•
Propionic acidemia (PA) therapeutic: In an ongoing Phase 1/2 study designed to evaluate safety and pharmacology in trial 
participants with PA, our investigational therapeutic (mRNA-3927) has been generally well-tolerated to date with no events 
meeting protocol-defined dose-limiting toxicity criteria. Early results suggest potential decreases in annualized metabolic 
decompensation event (MDE) frequency compared to pre-treatment, and the majority of patients have elected to continue on 
the open label extension study. We began generating registrational trial data in 2024.
•
Methylmalonic acidemia (MMA) therapeutic: Our investigational therapeutic for MMA (mRNA-3705) has been selected by 
the FDA for the Support for Clinical Trials Advancing Rare Disease Therapeutics (START) pilot program. We and the FDA 
have agreed on the pivotal study design. We expect to start a registrational study in the first half of 2025.
Other Business Updates
In March 2024, we entered into a development and commercialization funding agreement with Blackstone Life Sciences (Blackstone) 
to advance our flu program. As part of the agreement, Blackstone has committed up to $750 million in funding to support 
development efforts. Blackstone will be eligible for low-single digit royalties and milestone payments based on cumulative net sales of 
85

our future flu and combination vaccines, contingent upon regulatory approval in the U.S. and the success of the funded activities. The 
funding is recognized as a reduction to the expenses of our flu program. We will retain full rights and control of our flu program.
In April 2024, we entered a non-exclusive out-licensing agreement with a pharmaceutical company based in Japan for mRNA 
COVID-related intellectual property for the territory of Japan. We received an upfront payment of $50 million, which includes a $20 
million prepayment creditable against future royalties. Additionally, we are entitled to low double-digit royalties on the net sales of the 
company’s COVID product.
In June 2024, we were awarded up to $176 million through the Rapid Response Partnership Vehicle (RRPV), funded by BARDA, to 
accelerate the development of mRNA-based pandemic influenza vaccines. The project award will support the late-stage development 
of an mRNA-based vaccine to enable the licensure of a pre-pandemic vaccine against the H5 influenza virus. This subtype of the 
influenza virus causes a highly infectious and severe disease in birds known as avian influenza and poses a risk of spillover into the 
human population. The agreement also includes additional options to prepare for and accelerate responses to future public health 
threats.
During the third quarter of 2024, we updated our COVID vaccine to target the KP.2 and JN.1 strains of the SARS-CoV-2 virus for the 
2024-2025 season, consistent with guidance from regulators. Our vaccine targeting the KP.2 strain received approval from the FDA 
and Health Canada, while our vaccine targeting the JN.1 strain was approved by regulatory authorities in the European Union (EU), 
the United Kingdom, Japan, Taiwan, and other jurisdictions.
In May 2024, the FDA approved mRESVIA to protect adults aged 60 years and older from lower respiratory tract disease caused by 
RSV infection. The approval was granted under a breakthrough therapy designation. Subsequently, the Advisory Committee on 
Immunization Practices (ACIP) issued a recommendation for all unvaccinated people 75 years of age and older and unvaccinated 
people aged 60 to 74 who are at increased risk. In August 2024, the European Commission (EC) granted marketing authorization for 
mRESVIA to protect adults aged 60 years and older from lower respiratory tract disease caused by RSV infection. The authorization is 
valid in all 27 EU member states, as well as Iceland, Liechtenstein and Norway. We have also filed for mRNA-1345 approval with 
regulators in multiple markets worldwide and commenced sales in the U.S. in the third quarter of 2024.
In September 2024, our manufacturing facility in Laval, Quebec, received a Drug Establishment License (DEL) from Health Canada, 
certifying the site’s compliance with the required safety and quality standards to produce drug substance. This certification marked a 
significant step in enabling our Canadian facility to become fully operational, supporting domestic manufacturing of mRNA vaccines, 
including COVID vaccines, with production expected to begin in 2025.
In January 2025, we entered into a new agreement with the RRPV, funded by BARDA. The agreement provides up to $590 million to 
support the late-stage development and licensure of mRNA-based pre-pandemic influenza vaccines. In addition, the funding will 
enable the expansion of clinical studies for up to five additional subtypes of pandemic influenza, enhancing our preparedness to 
address emerging public health threats.

As of December 31, 2024, we have two commercial products authorized for use, our COVID vaccine and our RSV vaccine. The RSV 
vaccine was approved by the FDA in May 2024 for adults aged 60 years and older.
In the third quarter of 2023, we commenced sales of our COVID vaccine to the U.S. commercial market, in addition to continuing 
sales to foreign governments and international organizations. We also commenced sales of our RSV vaccine in the third quarter of 
2024. In the U.S., our COVID and RSV vaccines are sold primarily to wholesalers and distributors, and to a lesser extent, directly to 
retailers and healthcare providers. Net product sales are recognized net of estimated wholesaler chargebacks, invoice discounts for 
prompt payments and pre-orders, provisions for sales returns and government rebates, and other related deductions.

_______
(1)Includes an adjustment of approximately $216 million for the full year 2024, reflecting a reduction in prior year provision estimates, 
primarily related to returns and chargebacks for the previous COVID vaccine season.
Prior to the third quarter of 2023, we sold our COVID vaccine to the U.S. Government, foreign governments and international 
organizations. The agreements and related amendments with these entities generally do not include variable consideration, such as 
discounts, rebates or returns. Certain of these agreements entitle us to upfront deposits for our COVID vaccine supply, initially 
recorded as deferred revenue. As of December 31, 2024, we had deferred revenue of $188 million associated with customer deposits 
received or billable under supply agreements for delivery of our COVID vaccine, with the majority in 2025. 
Other revenue 
Other revenue comprises grant revenue, collaboration revenue, and licensing and royalty revenue. Grant and collaboration revenues 
have been primarily derived from government-sponsored and private organizations including the Biomedical Advanced Research and 
87

Development Authority (BARDA), the Defense Advanced Research Projects Agency (DARPA) and the Gates Foundation and from 
strategic alliances with Merck & Co., Inc (Merck), Vertex Pharmaceuticals Incorporated and Vertex Pharmaceuticals (Europe) 
Limited (together, Vertex) and others to discover, develop, and commercialize potential mRNA medicines. Licensing and royalty 
revenue is related to our out-licensing agreement for mRNA COVID related intellectual property in Japan, executed in 2024.

Cost of sales
Cost of sales includes raw materials, personnel and facility and other costs associated with manufacturing our commercial products. 
These costs include production materials, production costs at our manufacturing facilities, third-party manufacturing costs, and final 
formulation and packaging costs. Cost of sales also includes shipping costs, indirect overhead costs associated with our product sales 
during the period, third-party royalties on net sales of our products, and charges for inventory valuation, excess and obsolete inventory 
and losses on firm purchase commitments. 
Research and development expenses
The nature of our business and primary focus of our activities generate a significant amount of research and development costs.
Research and development expenses represent costs incurred by us for the following:
•
cost to develop our platform;
•
discovery efforts leading to development candidates;
•
preclinical, nonclinical, and clinical development costs for our programs;
•
cost to develop our manufacturing technology and infrastructure; and
•
digital infrastructure costs related to our drug discovery efforts and clinical trials.
The costs above comprise the following categories:
•
personnel-related expenses, including salaries, benefits, and stock-based compensation expense;
•
expenses incurred under agreements with third parties, such as consultants, investigative sites, contract research 
organizations (CROs), that conduct our preclinical studies and clinical trials, and in-licensing arrangements;
•
expenses associated with developing manufacturing, modification of formulation or design of a product or process, 
advancing the design to meet specific functional and economic requirements for manufacture and obtaining materials for 
preclinical studies, clinical trials and pre-launch inventory from internal and third-party contract manufacturing 
organizations (CMOs);
•
expenses incurred for the procurement of materials, laboratory supplies, and non-capital equipment used in the research 
and development process; 
•
upfront fees and milestones paid to third-parties for licenses and technologies that had not reached technological 
feasibility and did not have an alternative future use; and
•
facilities, depreciation, and amortization, and other direct and allocated expenses incurred as a result of research and 
development activities.
We use our employee and infrastructure resources for the advancement of our platform, and for discovering and developing programs. 
Due to the number of ongoing programs and our ability to use resources across several projects, indirect or shared operating costs 
incurred for our research and development programs are generally not recorded or maintained on a program- or therapeutic area-
specific basis.

__________
(1) Includes a total of 34 development candidates at December 31, 2024, 42 development candidates at December 31, 2023, and 45 
development candidates at December 31, 2022. Program-specific expenses are reflected as of the beginning of the period in which 
the program was internally advanced to development.
The program-specific expenses by therapeutic area summarized in the table above include external development costs, such as fees 
paid to outside consultants, central laboratories, investigative sites, and CROs in connection with our preclinical studies and clinical 
trials. We generally do not allocate personnel-related costs, including stock-based compensation, costs associated with our general 
platform research, technical development, and other shared costs on a program-specific basis. These costs were therefore excluded 
from the summary of program-specific expenses by therapeutic area. 
Discovery and platform research expenses include costs associated with early-stage research activities for preclinical programs and the 
development of technical advances in mRNA science, delivery science, and manufacturing process design. These costs include 
external CRO and lab services, personnel-related costs, computer equipment, facilities, and other administrative costs.
Technology development and manufacturing expenses are primarily related to manufacturing process development and manufacturing 
costs, including expenses for acquiring and manufacturing pre-launch inventory, mRNA supply for preclinical studies and clinical 
trials.
Shared discovery and development expenses are research and development costs such as personnel-related costs and other costs, such 
as the purchase of priority review vouchers. These expenses are not otherwise included in development programs, discovery and 
platform research, technical development, manufacturing expenses, or stock-based compensation. 
Historically, we have made substantial investments in research and development activities, including development of our platform, 
mRNA technologies, and manufacturing technologies. We expense research and development costs as incurred and cannot reasonably 
estimate the nature, timing, and estimated costs required to complete the development of the development candidates and 
investigational medicines we are currently developing or may develop in the future. 
Changes in expectations or outcomes of any of the known or unknown risks and uncertainties may materially impact our expected 
research and development expenditures. Continued research and development is central to the ongoing activities of our business. 
Investigational medicines in later stages of clinical development, such as our norovirus vaccine, seasonal flu vaccine, new generations 
of COVID vaccines, combination vaccines, CMV vaccine, and our INT program, generally have higher development costs than those 
in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. We expect our 
research and development costs to be substantial in the near term as our investigational medicines advance through development 
phases and as we identify and develop additional programs. 
89

There are numerous factors associated with the successful commercialization of any of our investigational medicines, including future 
trial design and various regulatory requirements, many of which cannot be determined with accuracy at this time due to the early stage 
of development of many of our investigational medicines. Moreover, future commercial and regulatory factors beyond our control will 
impact our clinical development programs and plans.
Selling, general and administrative expenses
Selling, general and administrative expenses consist primarily of personnel-related costs, including stock-based compensation, for 
executives, finance, legal, human resources, business development, commercial, marketing, and other administrative and operational 
functions, professional fees, accounting and legal services, information technology and facility-related costs, and expenses associated 
with obtaining, maintaining, and defending intellectual property (IP). These costs relate to the operation of the business, unrelated to 
the research and development function, or any individual program.
Prior to 2024, selling, general and administrative expenses increased annually as we expanded our commercial infrastructure to 
support the global commercialization of our COVID vaccine. These increases were driven by investments in building regulatory, sales, 
and marketing teams, establishing subsidiaries in multiple countries, and supporting operational growth. In 2024, selling, general and 
administrative expenses decreased significantly by $375 million, or 24%, compared to 2023. This decline reflects our focus on 
productivity improvements, cost-saving initiatives, and targeted investments that strengthen our overall efficiency.
Interest income
Interest income consists of interest generated from our investments in cash and cash equivalents, money market funds, and high-
quality fixed income securities.
Other expense, net
Other expense, net consists of interest expense, gains or losses related to the sale of investments in marketable securities, changes in 
fair value of investments in equity securities, foreign currency transactions, remeasurements and hedges, and other income and 
expense unrelated to our core operations. Interest expense is primarily derived from our finance leases related to our Moderna 
Technology Center prior to its acquisition in December 2024, and certain contract manufacturing service agreements.
Critical accounting policies and significant judgments and estimates
Our management’s discussion and analysis of our financial condition and results of operations is based on our consolidated financial 
statements, which have been prepared in accordance with U.S. generally accepted accounting principles. The preparation of these 
consolidated financial statements requires us to make judgments and estimates that affect the reported amounts of assets, liabilities, 
revenues, and expenses and the disclosure of contingent assets and liabilities in our consolidated financial statements. We base our 
estimates on historical experience, known trends and events, and various other factors that we believe to be reasonable under the 
circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not 
readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. On an 
ongoing basis, we evaluate our judgments and estimates in light of changes in circumstances, facts, and experience. The effects of 
material revisions in estimates, if any, are reflected in the consolidated financial statements prospectively from the date of change in 
estimates.
While our significant accounting policies are described in more detail in the notes to our consolidated financial statements appearing 
elsewhere in this Annual Report on Form 10-K, we believe the following accounting policy used in the preparation of our 
consolidated financial statements require the most significant judgments and estimates.
Net product sales
Prior to the third quarter of 2023, we sold our COVID vaccine to the U.S. Government, foreign governments and organizations. The 
agreements and related amendments with these entities generally do not include variable consideration, such as discounts, rebates or 
returns. In the third quarter of 2023, we commenced sales of our latest COVID vaccine to the U.S. commercial market, in addition to 
continuing sales to foreign governments and organizations. We also commenced sales of our RSV vaccine in the third quarter of 2024. 
In the U.S., our COVID vaccine and RSV vaccine are sold primarily to wholesalers and distributors, and to a lesser extent, directly to 
retailers and healthcare providers.
We recognize net product sales when control of the product transfers to the customer, typically upon delivery. Net product sales are 
recognized net of estimated wholesaler chargebacks, invoice discounts for prompt payments and pre-orders, provisions for sales 
90

returns, government rebates, and other related deductions. These provisions are recorded based on contractual terms, our estimate of 
returns for product sold, and other relevant considerations, during the period, using the expected value method or the most likely 
amount method. Estimates are assessed each period and adjusted as required to revise information or actual experience. Please refer to 
Note 2 to our consolidated financial statements for further discussion and analysis of each significant category of product sales 
provisions and the accounting policy.
The application of our critical accounting policies necessitates substantial management judgment and estimation, particularly when 
determining the amount of variable consideration to recognize. The subjectivity of this process is heightened when assessing factors 
outside our direct control such as the limited historical data, constrained third-party information, and evolving market dynamics. 
Among all variables, estimating returns presents the most significant judgment due to the broad range of potential outcomes and the 
current lack of established return trends. While we now have one year of data on our product returns, this remains insufficient to 
establish reliable patterns. We will continue to enhance our projections as additional information becomes available. The actual results 
could differ from our estimates, and such differences could have a material impact to our financial statements.

Revenue
Total revenue decreased by $3.6 billion, or 53%, in 2024, primarily attributable to a significant reduction in net product sales of our 
COVID vaccine. Net product sales decreased by $3.6 billion, or 53%, in 2024, mainly due to lower sales volumes in Europe and the 
rest of the world. This decline reflects the transition to a seasonal commercial market for COVID vaccine, as revenue from these 
regions was previously generated largely through advance purchase agreements with foreign governments and international 
organizations during the pandemic. In the United States, sales remained relatively consistent compared to 2023. However, 2024 sales 
include an approximately $216 million benefit related to a reversal of prior-year sales provisions. Excluding this adjustment, product 
sales volume in the United States declined compared to 2023, primarily due to lower vaccination rates and increased market 
91

competition. Although we commenced sales of our RSV vaccine in the third quarter of 2024, these sales did not have a significant 
impact on our overall product sales for the year. Other revenue decreased by $50 million, or 28%, in 2024, primarily due to lower 
grant and collaboration revenue, partially offset by license and royalty revenue related to the licensing agreement for mRNA COVID-
related intellectual property in Japan, executed in 2024.  
Product sales are expected to decline further in 2025, driven by a potential reduction in vaccination rates, lower sales under advanced 
purchase agreements as most have been fulfilled, and increasing competitive pressures in the market.
Operating expenses
Cost of sales
Our cost of sales was $1.5 billion, or 47% of our net product sales, in 2024, including third-party royalties of $155 million, inventory 
write-downs of $495 million, primarily for raw materials and our finished and semi-finished COVID vaccine inventory, wind-down 
costs of $263 million, unutilized manufacturing capacity of $105 million, and losses from non-cancellable raw material purchase 
commitments of $60 million. Our cost of sales was $4.7 billion, or 70% of our net product sales, in 2023, including third-party 
royalties of $301 million, inventory write-downs of $2.2 billion, unutilized manufacturing capacity and wind down costs of $981 
million, and losses on firm purchase commitments and cancellation fees of $205 million. These charges in 2024, other than royalties, 
were largely driven by customer demand forecast adjustments, termination of third-party contract manufacturing service agreements, 
and commitments for manufacturing capacity and raw material purchase agreements. Charges in 2023, other than royalties, were 
primarily attributable to a shift in product demand to the latest variant-targeted COVID vaccine and a decline in customer demand, 
which ultimately led to our strategic initiative implemented in the third quarter of 2023 to optimize our COVID business by resizing 
manufacturing operations in response to the shift toward an endemic seasonal market. Refer to Note 7 to our consolidated financial 
statements for further details on inventory related charges and this initiative.
Cost of sales for 2024 decreased by $3.2 billion, or 69%, compared to 2023. Cost of sales as a percentage of net product sales for 2024 
decreased by 23 percentage points to 47% from 70% in 2023. The decrease in cost of sales was primarily driven by reduced inventory 
write-downs, unutilized manufacturing capacity, purchase commitment and cancellation fees, and lower sales volume. Additionally, 
the reduction reflects the impact of our strategic initiative launched, which incurred $1.6 billion in charges during 2023, contributed to 
improved manufacturing efficiency and cost reductions in 2024. Of the wind-down costs incurred in 2024, $238 million related to the 
termination of a contract manufacturing agreement during the fourth quarter, as part of our continued efforts to optimize our 
manufacturing footprint in alignment with the transition to a seasonal endemic market. The decrease in cost of sales as a percentage of 
net product sales was primarily attributable to these reduced costs, partially offset by the lower product sales. 
In 2025, we anticipate a reduction in cost of sales, primarily due to lower anticipated product sales. However, we expect cost of sales 
as a percentage of net product sales to increase compared to 2024, driven by excess manufacturing capacity and the impact of fixed 
costs being allocated across a lower sales volume.
Research and development expenses
Research and development expenses decreased by $302 million, or 6%, in 2024. The decrease was primarily attributable to 
decreases in clinical trial expenses of $427 million, clinical manufacturing expenses of $286 million, and preclinical research expenses 
of $246 million. These reductions were partially offset by an increase of $231 million in personnel-related costs, including stock-based 
compensation, and the purchase of two priority review vouchers. The decrease was largely attributable to reduced spending across our 
COVID, RSV, seasonal flu, CMV and combination vaccine programs. The decrease in expenses for the seasonal flu program was 
primarily due to funding provided by Blackstone. Please refer to Note 5 to our consolidated financial statements for details on the 
research and development funding arrangement with Blackstone. These reductions were partially offset by increased spending on our 
norovirus and INT programs. The increase in personnel-related costs and stock-based compensation was mainly due to higher 
headcount to support our continued research and development efforts.
We expect research and development costs to decline in 2025 as we focus our investments on prioritized programs and strategic areas, 
aligning resources with our long-term objectives. However, we still anticipate incurring a significant amount of research and 
development expenses in 2025 as we continue to develop our pipeline and advance our product candidates into later-stage 
development, in particular those in ongoing Phase 3 studies, including our norovirus, flu+COVID combination, CMV, and RSV 
vaccine programs, as well as our INT program. 
92

Selling, general and administrative expenses
Selling, general and administrative expenses decreased by $375 million, or 24%, in 2024. The decrease was mainly due to a $342 
million reduction in consulting and outside services across all functions, along with a $72 million reduction in commercial and 
marketing expenses. The decrease reflects cost discipline and operational efficiencies gained by reducing reliance on external 
consultants and bringing more functions in-house.
While we continue to make selective investments to support our key priorities, we expect a slight decrease in spending in 2025 as we 
maintain an efficient and scalable operational structure. 
Interest income
Interest income generated from our investments in marketable securities increased by $4 million in 2024, mainly attributable to an 
overall higher interest rate environment, partially offset by lower average investment balances.

Total other expense, net decreased by $37 million, or 30%, in 2024. The decrease was primarily driven by a reduction in net realized 
losses on available-for-sale debt securities and lower interest expense. Interest expense, which is primarily related to our finance 
leases, declined due to the termination or expiration of certain finance leases in 2023. Please refer to Note 10 to our consolidated 
financial statements for additional information.
Provision for income taxes
Provision for income taxes decreased by $818 million, or 106%, in 2024, primarily due to the establishment of a $1.7 billion valuation 
allowance on deferred tax assets in the third quarter of 2023. This valuation allowance has been applied consistently since its initial 
recognition. Our effective tax rate for the year ended December 31, 2024 was 1.3%, which is lower than the statutory rate. It is mainly 
driven by the increase in valuation allowances on deferred tax assets, partially offset by tax benefits from research and development 
credits. As a result of the valuation allowance, the 2024 effective tax rate is not comparable to the prior year. Please refer to Note 13 to 
our consolidated financial statements for additional details.

Our cash, cash equivalents and investments are invested in accordance with our investment policy, primarily with a view to liquidity 
and capital preservation. Our investments, consisting primarily of government and corporate debt securities, are stated at fair value. 
Cash, cash equivalents and investments as of December 31, 2024 decreased by $3.8 billion, or 28%, compared to December 31, 2023. 
For the year ended December 31, 2024, we had a net cash outflow from operations of $3.0 billion, and purchases of property, plant 
and equipment of $1.1 billion.
Working capital, defined as current assets less current liabilities, as of December 31, 2024 decreased by $1.4 billion, or 19%, 
compared to December 31, 2023. This was primarily due to a $1.6 billion decrease in cash, cash equivalents and short-term 
investments, mainly used to fund our operating activities, and a $534 million decrease in accounts receivable, primarily driven by 
timing of collections. These decreases were partially offset by a $415 million reduction in short-term deferred revenue, mainly 
resulting from revenue recognized from deferred revenue in excess of customer deposits received, and a $371 million decrease in 
accrued liabilities, reflecting an overall reduction in spend.

Operating activities
We derive cash flows from operations primarily from cash collected from customer deposits and accounts receivable related to our 
product sales, as well as certain government-sponsored and private organizations, strategic alliances and funding arrangements. Our 
cash flows from operating activities are significantly affected by our use of cash for operating expenses and working capital to support 
the business. Beginning in the third quarter of 2020, we entered into supply agreements with the U.S. Government, foreign 
governments and international organizations for the supply of our COVID vaccine and received upfront deposits. In the third quarter 
of 2023, we commenced sales of our COVID vaccine to the U.S. commercial market, in addition to continuing sales to foreign 
governments and international organizations. In the U.S., our COVID vaccine is sold primarily to wholesalers and distributors, and to 
a lesser extent, directly to retailers and healthcare providers. We also commenced sales of our RSV vaccine in the third quarter of 
2024. Wholesalers and distributors typically do not make upfront payments to us. As of December 31, 2024, we had $188 million in 
deferred revenue related to customer deposits received or billable.
Net cash used by operating activities in 2024 was $3.0 billion and consisted of net loss of $3.6 billion and non-cash adjustments of 
$635 million, plus a net change in assets and liabilities of $78 million. Non-cash items primarily included stock-based compensation 
of $429 million and depreciation and amortization of $189 million. The net change in assets and liabilities was primarily due to a 
decrease in deferred revenue of $439 million due to revenue recognized from deferred revenue in excess of customer deposits 
received, and a decrease in accounts payable and accrued liabilities of $454 million resulting from overall lower spend in the period. 
These were partially offset by a decrease in accounts receivable of $534 million, mainly due to timing of collections, a decrease in 
prepaid expenses and other assets of $145 million, primarily driven by reductions in vendor prepayments, as well as a decrease in 
inventory of $83 million, largely due to inventory sold and write-downs.
Net cash used by operating activities decreased by $114 million, or 4%, in 2024 compared to 2023. This decrease was primarily driven 
by a decrease in net loss of $1.2 billion, a change in deferred revenue of $1.6 billion, reflecting less revenue recognized from deferred 
revenue in excess of customer deposits received in 2024. This was partially offset by a change in prepaid expenses and other assets of 
$1.7 billion, mainly due to a decrease in deferred income tax assets in 2023 resulting from the establishment of a valuation allowance 
and reductions in vendor prepayments, and a change in inventory of $664 million, driven by a smaller reduction in inventory write-
downs.
Investing activities
Our primary investing activities consist of purchases, sales, and maturities of our investments, capital expenditures for land, building, 
leasehold improvements, manufacturing, laboratory, computer equipment and software, and business development.
94

Net cash provided by investing activities in 2024 was $1.9 billion, which primarily included proceeds from maturities of marketable 
securities of $5.6 billion and proceeds from sales of marketable securities of $4.0 billion, partially offset by purchases of marketable 
securities of $6.5 billion, and purchases of property, plant and equipment of $1.1 billion.
Net cash flows provided by investing activities decreased by $2.3 billion, or 54%, in 2024 compared to 2023, primarily due to 
increases in purchases of marketable securities of $2.8 billion, and purchases of property, plant and equipment of $344 million, 
partially offset by an increase in proceeds from sale of marketable securities of $761 million.
Financing activities
Our primary financing activities consist of issuance of common stock related to our equity plans, repurchases of common stock, and 
finance leases. 
Net cash provided by financing activities in 2024 was $56 million, consisting of net proceeds from the issuance of common stock in 
connection with the exercise of stock options and employee stock purchases under our equity plans of $66 million.
Net cash provided by financing activities increased by $1.4 billion, or 104%, in 2024 compared to 2023, mainly due to a decrease in 
repurchases of common stock.
Operation and funding requirements
Our principal sources of funding as of December 31, 2024 consisted of cash and cash equivalents, investments, and cash we may 
generate from operations. We reported a net loss of $3.6 billion and $4.7 billion for the years ended December 31, 2024 and 2023, 
respectively. In contrast, we generated net income of $8.4 billion and $12.2 billion for the years ended December 31, 2022 and 2021, 
respectively, following the authorization of our first commercial product in December 2020. From our inception to the end of 2020, 
we incurred significant losses from operations due to our significant research and development expenses. We have retained earnings of 
$10.0 billion as of December 31, 2024. 
We have significant future capital requirements including expected operating expenses to conduct research and development activities, 
operate our organization, and meet capital expenditure needs. We anticipate maintaining substantial expenses across all areas of our 
ongoing activities, particularly as we continue research and development of our development candidates and clinical activities for our 
investigational medicines. This also extends to our manufacturing costs, including our arrangements with our supply and 
manufacturing partners. Our ongoing work on our norovirus, flu+COVID combination, CMV, RSV, and next-generation COVID 
vaccine candidates, INT, development of any new COVID vaccines against variants of SARS-CoV-2, late-stage clinical development, 
investments in digital capabilities and artificial intelligence technologies, and buildout of global commercial, regulatory, sales and 
marketing infrastructure and manufacturing facilities will require significant cash outflows in future periods, most of which may not 
be reimbursed or otherwise paid for by our partners or collaborators. In addition, we have substantial facility, lease and purchase 
obligations. We have also entered into various collaboration and licensing agreements, as well as a research and development funding 
arrangement with a third party. These arrangements collectively encompass the funding of specific research and development 
activities, with the distinction that under the research and development funding arrangement, we receive funding. However, for all 
these arrangements, we may be obligated to make potential future milestone and royalty payments.
We believe that our cash, cash equivalents, and investments as of December 31, 2024, together with cash expected to be generated 
from product sales, will be sufficient to enable us to fund our projected operations and capital expenditures through at least the next 12 
months from the issuance of the financial statements included in this Annual Report on Form 10-K. We are subject to all the risks 
related to the development and commercialization of novel medicines, and we may encounter unforeseen expenses, difficulties, 
complications, delays, and other unknown factors, which may adversely affect our business. For example, we experienced a decline in 
customer demand for our COVID vaccine in 2023, and this trend continued into 2024, reflecting the market's ongoing transition to a 
seasonal commercial pattern in the endemic COVID vaccine market. We foresee that our commitment to investing in our business for 
future product launches may lead to continued negative cash flows from operations in upcoming periods. Our forecast of the period of 
time through which our financial resources will be adequate to support our operations is a forward-looking statement and involves 
risks and uncertainties, and actual results could vary as a result of a number of factors. We have based this estimate on assumptions 
that may prove to be wrong, and we could utilize our available capital resources sooner than we currently expect.

The amounts represent non-cancelable fixed payment obligations related to purchases of raw materials, contract manufacturing 
services, research and development and other goods or services in the normal course of business. As of December 31, 2024, $60 
million of the purchase commitments related to raw materials was recorded as an accrued liability for loss on future firm purchase 
commitments and is included in the purchase obligations line above.
We have agreements with certain vendors for various services, including services related to clinical operations and support and 
contract manufacturing, which we are not contractually able to terminate for convenience. Certain agreements provide for termination 
rights subject to termination fees or wind down costs. Under such agreements, we are contractually obligated to make certain 
payments to vendors, mainly to reimburse them for their unrecoverable outlays incurred prior to cancellation. The exact amounts of 
such obligations are dependent on the timing of termination, and the exact terms of the relevant agreement and cannot be reasonably 
estimated. At December 31, 2024, we had cancelable open purchase orders of $2.9 billion in total under such agreements for our 
clinical operations and support and contract manufacturing. These amounts represent only our estimate of those items for which we 
had a contractual commitment to pay at December 31, 2024, assuming we would not cancel these agreements. The actual amounts we 
pay in the future to the vendors under such agreements may differ from the cancelable open purchase order amounts of $2.9 billion.
In addition to the above obligations, we enter into a variety of agreements and financial commitments in the normal course of 
business. The terms generally allow us the option to cancel, reschedule, and adjust our requirements based on our business needs, prior 
to the delivery of goods or performance of services. It is not possible to predict the maximum potential amount of future payments 
under these agreements due to the conditional nature of our obligations and the unique facts and circumstances involved in each 
particular agreement.
As of December 31, 2024, we did not have any off-balance sheet arrangements, other than those obligations and commitments 
disclosed herein, that were material or reasonably likely to become material to our financial condition or results of operations.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk
Interest Rate Risk
As of December 31, 2024 and 2023, we had cash, cash equivalents, restricted cash, and investments in marketable securities of $9.5 
billion and $13.3 billion, respectively. Our investment portfolio comprises money market funds and marketable debt securities 
(including U.S. Treasury securities, debt securities of U.S. government agencies and corporate entities, and commercial paper), which 
are classified as available-for-sale securities. Our primary investment objectives are the preservation of capital and the maintenance of 
liquidity, and our investment policy defines allowable investments based on quality of the institutions and financial instruments 
designed to minimize risk exposure. Our exposure to interest rate sensitivity is affected by changes in the general level of U.S. interest 
rates. 
Our marketable securities are subject to interest rate risk and will fall in value if market interest rates increase. Due to the short-term 
maturities and low risk profiles of our investments, we do not anticipate a significant exposure to interest rate risk. If market interest 
rates were to increase immediately and uniformly by one percentage point from levels at December 31, 2024, the net fair value of our 
marketable securities would decrease by approximately $53 million.
Foreign Currency Risk
We transact business in various foreign currencies and have international sales and expenses denominated in foreign currencies. 
Therefore, we are exposed to certain risks arising from both our business operations and economic conditions. For the year ended 
December 31, 2024, our revenue generating activities and operations continued to be primarily denominated in U.S. dollars. However, 
we maintained a significant exposure to foreign currency risk, particularly in the Australian dollar, Brazilian real, British pound, and 
Canadian dollar markets.  
As our business evolves, we have transitioned to receiving payments in local currencies rather than U.S. dollars. In addition, we 
operate in foreign countries and are establishing manufacturing facilities in Canada, Australia, and the United Kingdom, where we 
also transact in foreign currencies. Collectively, these factors expose us to risks associated with fluctuations in foreign currency 
exchange rates, which may impact our results of operations and cash flows. To manage this exposure, we have focused on balance 
sheet hedging activities as part of our strategy to address foreign currency fluctuations. While cash flow hedging programs are in 
place, there were no foreign currency cash flow hedging activities during 2024. 
Balance Sheet Hedging Activities
We enter into foreign currency forward contracts to hedge fluctuations associated with foreign currency denominated monetary assets 
and liabilities, primarily cash, receivables, payables and lease liabilities in the Australian dollar, Brazilian real, British pound, and 
Canadian dollar, that are not designated for hedge accounting treatment. Therefore, these forward contracts are accounted for as 
derivatives whereby the fair value of the contracts are reported as prepaid expenses and other current assets or other current liabilities 
in our consolidated balance sheets, and gains and losses resulting from changes in the fair value are recorded as a component of other 
expense, net, in our consolidated statements of operations. The gains and losses on these foreign currency forward contracts generally 
offset the gains and losses in the underlying foreign currency denominated assets and liabilities, which are also recorded to other 
expense, net, in our consolidated statements of operations. As of December 31, 2024, our outstanding balance sheet hedging 
derivatives, carried at fair value, had maturities of less than three months.
We enter into these foreign exchange contracts to hedge our monetary assets and liabilities denominated in foreign currency in the 
normal course of business and accordingly, they are not speculative in nature. We believe the counterparties to our foreign currency 
forward contracts are creditworthy multinational commercial banks. While we believe the risk of counterparty nonperformance is not 
material, a sustained decline in the financial stability of financial institutions as a result of disruption in the financial markets could 
affect our ability to secure creditworthy counterparties for our foreign currency hedging programs.
Notwithstanding our efforts to mitigate some foreign currency exchange risks, there can be no assurance that our hedging activities 
will adequately protect us against the risks associated with foreign currency fluctuations. As of December 31, 2024, a hypothetical 
adverse movement of 10 percent in foreign currency exchange rates compared to the U.S. dollars across all maturities would have 
resulted in potential declines in the fair value on our foreign currency forward contracts used in balance sheet hedging of 
approximately $36 million. We expect that any increase or decrease in the fair value of the portfolio would be substantially offset by 
increases or decreases in the underlying exposures being hedged.

Report of Independent Registered Public Accounting Firm
To the Stockholders and the Board of Directors of Moderna, Inc.
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of Moderna, Inc. (the Company) as of December 31, 2024 and 2023, 
the related consolidated statements of operations, comprehensive income (loss), stockholders’ equity, and cash flows for each of the 
three years in the period ended December 31, 2024, and the related notes (collectively referred to as the “consolidated financial 
statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the 
Company at December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the three years in the period 
ended December 31, 2024, in conformity with U.S. generally accepted accounting principles.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(PCAOB), the Company's internal control over financial reporting as of December 31, 2024, based on criteria established in Internal 
Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) 
and our report dated February 21, 2025, expressed an unqualified opinion thereon.
Basis for Opinion
These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the 
Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to 
be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and 
regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit 
to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. 
Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to 
error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence 
regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used 
and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe 
that our audits provide a reasonable basis for our opinion.
Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was 
communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material 
to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of the 
critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, 
by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or 
disclosure to which it relates.

Provisions for returns on product sales
Description of 
the Matter
During the year ended December 31, 2024, the Company’s net product sales were $3.1 billion. As explained 
in Note 2 of the consolidated financial statements, revenue from product sales includes estimates of variable 
consideration for which provisions are established, including provisions for product sales returns.
Auditing the Company’s measurement of provisions for product sales returns under its contracts with 
wholesalers, distributors and retail customers (collectively, “Customers”) was especially challenging because 
(1) it involves management assumptions about inventory remaining in the distribution channel as of the 
balance sheet date that could be subject to return in future periods and projected market demand, and (2) the 
Company has limited returns history on which to base its assumptions. 
How We 
Addressed the 
Matter in Our 
Audit
We obtained an understanding, evaluated the design and tested the operating effectiveness of internal controls 
over the Company’s process to determine provisions for returns on product sales. For example, we tested 
controls over management’s review of the completeness and accuracy of the data used in the process and the 
assumptions about the amount of inventory in the distribution channel that could be subject to return in future 
periods. 
To test the Company’s provisions for returns on product sales, our audit procedures included, among other 
procedures, testing the accuracy and completeness of the underlying data used in the calculations and 
evaluating the assumptions used by management to estimate its provisions. To test management’s 
assumptions, we inspected agreements with significant Customers to validate the rights of return, made 
inquiries of members of the commercial function regarding any changes to the terms and conditions of 
commercial contracts, and assessed the historical accuracy of management’s estimate. We also examined 
credit memos issued during and after year end for unusual items or trends not consistent with the Company’s 
analysis of product returns and performed revenue cutoff testing at period end to assess whether there were 
unusual trends that should have been considered in the Company analysis of product returns. In addition, we 
reviewed inventory on hand-reporting from significant Customers at the balance sheet date and subsequent to 
the balance sheet date and inspected vaccination data from third-party sources through the report date. We also 
performed sensitivity analyses over the Company’s return rate to assess the effect of changes in assumptions.

MODERNA, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
1. Description of the Business
Moderna, Inc. (collectively, with its consolidated subsidiaries, any of Moderna, we, us, our or the Company) is a biotechnology 
company advancing a new class of medicines made of messenger RNA (mRNA). mRNA medicines are designed to direct the body’s 
cells to produce intracellular, membrane or secreted proteins that have a therapeutic or preventive benefit with the potential to address 
a broad spectrum of diseases. Our platform builds on continuous advances in basic and applied mRNA science, delivery technology 
and manufacturing, providing us the capability to pursue in parallel a robust pipeline of new development candidates. We are 
developing medicines across four franchises: respiratory virus vaccines, latent and other virus vaccines, oncology therapeutics and rare 
disease therapeutics.
Our COVID vaccine is our first commercial product and is marketed, where approved, under the name Spikevax®. Our original 
vaccine, mRNA-1273, targeted the SARS-CoV-2 ancestral strain, and we have leveraged our mRNA platform to rapidly adapt our 
vaccine to emerging SARS-CoV-2 strains to provide protection as the virus evolves and regulatory guidance is updated.
In May 2024, the U.S. Food and Drug Administration (FDA) approved mRESVIA® (mRNA-1345), our mRNA respiratory syncytial 
virus (RSV) vaccine, to protect adults aged 60 years and older from lower respiratory tract disease caused by RSV infection. The 
approval was granted under a breakthrough therapy designation and marks the second approved mRNA product from Moderna.
We have a diverse and extensive development pipeline of 34 development candidates across our 44 development programs, of which 
41 are in clinical studies currently.
2. Summary of Significant Accounting Policies
Basis of Presentation and Principles of Consolidation
Our consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles (GAAP). Any 
reference in these notes to applicable guidance is meant to refer to the authoritative accounting principles generally accepted in the 
United States as found in the Accounting Standards Codification (ASC) and Accounting Standards Updates (ASU) of the Financial 
Accounting Standards Board (FASB).
The consolidated financial statements include the Company and its subsidiaries. All intercompany transactions and balances have been 
eliminated in consolidation.
Deferred tax assets, previously presented as a separate line item in our 2023 Form 10-K, are presented within other non-current assets 
in the consolidated balance sheets. Income taxes payable, previously presented as a separate line item in our 2023 Form 10-K, is 
presented within other current liabilities in the consolidated balance sheets. The associated prior period amounts in the consolidated 
financial statements, as well as in the notes thereto, have been reclassified to conform to the current presentation.
Use of Estimates
We have made estimates and judgments affecting the amounts reported in our consolidated financial statements and the accompanying 
notes. We base our estimates on historical experience and various relevant assumptions that we believe to be reasonable under the 
circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities at the date 
of the financial statements and the reported amounts of revenue and expenses during the reporting periods that are not readily apparent 
from other sources. Changes in our estimates are recorded in the financial results of the period in which the new information becomes 
available. The actual results that we experience may differ materially from our estimates.
Segment Information
The Company operates as a single operating and reportable segment, reflecting the integrated nature of our business focused on the 
research, development, and commercialization of mRNA-based medicines. Our Chief Executive Officer serves as the Chief Operating 
Decision Maker (CODM), responsible for assessing the Company's performance and making resource allocation decisions. The 
CODM evaluates financial information on a consolidated basis, focusing on key metrics such as total revenue, operating expenses, and 
net income or loss. The CODM allocates resources based on the Company's available cash resources, forecasted cash flow, and 
expenditures on a consolidated basis, as well as an assessment of the probability of success of its research and development activities. 
Resource allocation decisions are informed by budgeted and forecasted expense information, along with actual expenses incurred to 
107

date. Disaggregated profit or loss information at the program or functional level is not regularly provided to or relied upon by the 
CODM, as our integrated operating model emphasizes shared resources and centralized decision-making. The interdependent nature of 
our research, development, and commercialization activities, supported by common infrastructure such as our mRNA platform, makes 
further disaggregation of expenses less meaningful for assessing performance. Additionally, there are no segment managers 
accountable for operations, operating results, and planning for levels or components below the consolidated unit level. 
Revenue Recognition
To determine the appropriate amount of revenue to be recognized for arrangements that we determine are within the scope of ASC 
606, we perform the following five steps (the five-step model): (i) identify the contract(s) with our customer; (ii) identify the 
performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance 
obligations in the contract; and (v) recognize revenue when or as each performance obligation is satisfied. 
Net Product Sales 
Prior to the third quarter of 2023, we sold our COVID vaccine to the U.S. Government, foreign governments and organizations. The 
agreements and related amendments with these entities generally do not include variable consideration, such as discounts, rebates or 
returns. Certain of these agreements entitle us to upfront deposits for our COVID vaccine supply, initially recorded as deferred 
revenue. In the third quarter of 2023, we commenced sales of our COVID vaccine to the U.S. commercial market, in addition to 
continuing sales to international governments and organizations. We also commenced sales of our RSV vaccine in the third quarter 
of 2024. In the U.S., our COVID vaccine and RSV vaccine are sold primarily to wholesalers and distributors, and to a lesser extent, 
directly to retailers and healthcare providers. Wholesalers and distributors typically do not make upfront payments to us.
We recognize net product sales when control of the product transfers to the customer, typically upon delivery. Payment terms 
generally range from 30 to 60 days, in line with customary practices in each country. Net product sales are recognized net of estimated 
wholesaler chargebacks, invoice discounts for prompt payments and pre-orders, provisions for sales returns, government rebates, and 
other related deductions. These provisions are recorded based on contractual terms, our estimate of returns for product sold during the 
period, and other relevant considerations, using the expected value method or the most likely amount method. We update our estimates 
quarterly and record necessary adjustments in the period when we identify the adjustments. Product sales, net of provisions, are 
recorded only to the extent a significant reversal in the amount of cumulative revenue recognized is not probable when the uncertainty 
associated with the provisions is subsequently resolved. Shipping and handling activities are considered fulfillment activities and not a 
separate performance obligation. Taxes assessed by governmental authorities that are imposed on and collected from our product sales 
are excluded from net product sales.
Wholesaler chargebacks, discounts and fees
We contract with retailers, healthcare providers, and group purchasing organizations (GPO) to broaden our customer reach and offer 
contractual discounts. The chargeback represents the difference between the invoice price billed to the wholesaler and the negotiated 
price charged to the retailers, healthcare providers and GPO members. For distribution and related services, such as stocking and cold 
chain storage, we provide compensation to our wholesalers and distributors. We typically offer our customers invoice discounts on 
product sales for prompt payments and pre-orders. The estimation of these discounts and fees is based on contractual terms and our 
expectations regarding future customer payment behaviors. Wholesaler fees and invoice discounts are deducted from our gross 
product sales and accounts receivable at the time such product sales are recognized.
Product returns
We typically offer customers in the U.S. the right to return products, up to a certain limit as stipulated in our contracts. Estimated 
returns for our vaccines are determined considering available return rates for similar products, estimated levels of inventory in the 
distribution channel, projected market demand, and our historical experience with returns. The estimated amount for product returns is 
presented within accrued liabilities on our consolidated balance sheets and is deducted from our gross product sales in the period the 
related product sales are recognized.
Government rebates and other fees
Fees payable to third party payers and healthcare providers, along with fees to our direct customers that are settled via cash payments, 
including certain patient assistance programs, are recorded as accrued liabilities on our consolidated balance sheets. In 2024, we began 
recognizing Medicare rebates associated with our RSV product. The estimation of Medicare rebates requires judgment and is based on 
historical utilization trends, and the mix of customers and payers. The estimated liability for unpaid or unbilled rebates is presented as 
accrued liabilities on our consolidated balance sheets. For 2024, the product sales subject to Medicare rebates were immaterial. 
108

Determining the amount of variable consideration to recognize necessitates substantial judgment, especially when assessing factors 
outside our direct control, such as the limited historical data, constrained third-party information, and evolving market dynamics. 
Among all variables, estimating returns continues to present the most significant judgment due to the broad range of potential 
outcomes and the lack of established return trends. While we now have one year of data on our product returns, this remains 
insufficient to establish reliable patterns. We will continue to enhance our projections as additional information becomes available. 
The actual results could differ from our estimates, and such differences could have a material impact to our financial statements.
Other Revenue
Other revenue consists primarily of grant revenue, collaboration revenue, and licensing and royalty revenue. 
Grant revenue
We have contracts with government-sponsored and private organizations for research and development related activities that provide 
for payments for reimbursed costs, which may include overhead and general and administrative costs as well as a related profit 
margin. We recognize grant revenue from these contracts as we perform services under these arrangements when the funding is 
committed. Associated expenses are recognized when incurred as research and development expense. Grant revenue and related 
expenses are presented gross in the consolidated statements of operations as we have determined we are the primary obligor under the 
arrangements relative to the research and development services we perform as lead technical expert.
Collaboration Revenue
We have entered into strategic collaborations and other similar arrangements with third parties for research and other licenses, 
development and commercialization of certain products and product candidates. Such arrangements provide for various types of 
payments to us, including upfront fees, funding of research and development services and preclinical and clinical material, technical, 
development, regulatory, and commercial milestone payments, licensing fees, option exercise fees, and royalty and earnout 
payments on product sales. Such payments are often not commensurate with the timing of revenue recognition and therefore result 
in deferral of revenue recognition. We recognize revenue based on the amount of the transaction price that is allocated to each 
respective performance obligation when or as the performance obligation is satisfied by transferring a promised good or service to 
the customer. 
Licensing and Royalty Revenue 
License revenue is recognized when the license is granted to the licensee, provided no significant performance obligations remain. 
Royalty revenue is recognized based on sales by licensees when the underlying sales occur, in accordance with the terms of the 
licensing agreement and when collectibility is reasonably assured.
Cash and Cash Equivalents
We consider all highly liquid investments with an original maturity of 90 days or less from the date of purchase to be cash equivalents.
Restricted Cash
Restricted cash is composed of amounts held on deposit related to our lease arrangements. The funds are maintained in money market 
accounts and are recorded at fair value. Restricted cash is classified as either current or non-current based on the terms of the 
underlying arrangement and is included in either prepaid expenses and other current assets or other non-current assets in our 
consolidated balance sheets.

_______
(1)Included in prepaid expenses and other current assets in the consolidated balance sheets.
(2)Included in other non-current assets in the consolidated balance sheets. 
Investments
We invest our excess cash balances in marketable debt securities. We classify our investments in marketable debt securities as 
available-for-sale. We report our available-for-sale securities at fair value at each balance sheet date, and include any unrealized 
holding gains and losses (the adjustment to fair value) in accumulated other comprehensive income (loss), a component of 
stockholders’ equity. Realized gains and losses are determined using the specific-identification method, and are included in other 
expense, net in our consolidated statements of operations. We classify our available-for-sale securities as current or non-current based 
on each instrument’s underlying effective maturity date and for which we have the intent and ability to hold the investment for a 
period of greater than 12 months. Available-for-sale securities with maturities of less than 12 months are classified as current and are 
included in investments in the consolidated balance sheets. Available-for-sale securities with maturities greater than 12 months for 
which we have the intent and ability to hold the investment for greater than 12 months are classified as non-current and are included in 
investments, non-current in the consolidated balance sheets.
We evaluate securities for impairment at the end of each reporting period. Impairment is evaluated considering numerous factors, and 
their relative significance varies depending on the situation. Factors considered include whether a decline in fair value below the 
amortized cost basis is due to credit-related factors or non-credit-related factors, the financial condition and near-term prospects of the 
issuer, and our intent and ability to hold the investment to allow for an anticipated recovery in fair value. A credit-related impairment 
is recognized as an allowance on the balance sheet with a corresponding adjustment to earnings. Any impairment that is not credit- 
related is recognized in other comprehensive income (loss), net of applicable taxes. 
Investments in publicly traded equity securities with readily determinable fair values are recorded at quoted market prices for identical 
securities, with changes in fair value recorded in other expense, net, in our consolidated statements of operations. Investments in 
equity securities without readily determinable fair values are recorded at cost minus impairment, if any, adjusted for changes resulting 
from observable price changes in orderly transactions for identical or similar securities. Such adjustments are recorded in other 
expense, net, in our consolidated statements of operations.
Accounts Receivable, net
Accounts receivable, net represent amounts due from customers less wholesalers chargebacks, discounts and fees (please refer to our 
“Revenue Recognition” policy within Note 2 for product sales provision) and allowance for expected credit losses. Amounts payable 
to us are recorded as accounts receivable when our right to consideration is unconditional. To estimate the allowance for credit losses, 
we determine the allowance based on ongoing credit evaluation, historical experience and the aging of such receivables, among other 
factors. There was no allowance for doubtful accounts at December 31, 2024 or 2023. Additionally, bad debt expenses were 
immaterial for the years ended December 31, 2024, 2023 and 2022.
Concentrations of Credit Risk
Financial instruments that subject us to significant concentrations of credit risk consist primarily of cash, cash equivalents, restricted 
cash, marketable debt securities, and accounts receivable, net. Our investment portfolio comprises money market funds and 
marketable debt securities, including U.S. Treasury securities, debt securities of U.S. government agencies and corporate entities and 
commercial paper. Our cash management and investment policy limits investment instruments to investment-grade securities with the 
objective to preserve capital and to maintain liquidity until the funds can be used in business operations. We invest in a variety of 
financial instruments and limit the amount of credit exposure with any individual financial institution. Bank accounts in the United 
110

States are insured by the Federal Deposit Insurance Corporation (FDIC) up to $250,000. Our primary operating accounts significantly 
exceed the FDIC limits. 
We are also subject to credit risk from our accounts receivable, net related to our net product sales and strategic alliances. We sell our 
products primarily to wholesalers and distributors and other governments and organizations. We do not require collateral or other 
security to support accounts receivable. To date, we have not experienced material losses with respect to the collection of our accounts 
receivable.
Significant Customers
Our accounts receivable, net are generally unsecured and are from customers in different countries. We generated revenue from 
product sales to wholesalers and distributors and other governments and organizations, and to a lesser extent, grants made by 
government-sponsored and private organizations, and collaboration revenue from our strategic alliances.

Fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction 
between market participants at the measurement date. When determining the fair value measurements for assets and liabilities, which 
are required to be recorded at fair value, we consider the principal or most advantageous market in which we would transact and the 
market-based risk measurements or assumptions that market participants would use in pricing the asset or liability, such as risks 
inherent in valuation techniques, transfer restrictions and credit risk. ASC 820 (Fair Value Measurement) establishes a fair value 
hierarchy for instruments measured at fair value that distinguishes between assumptions based on market data (observable inputs) and 
our assumptions (unobservable inputs). Observable inputs are inputs that market participants would use in pricing the asset or liability 
based on market data obtained from our independent sources. Unobservable inputs are inputs that reflect our assumptions about the 
inputs that market participants would use in pricing the asset or liability, and are developed based on the best information available in 
the circumstances. The following fair value hierarchy is used to classify assets and liabilities based on the observable inputs and 
unobservable inputs used to value the assets and liabilities: 
•
Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted 
assets or liabilities;
•
Level 2: Quoted prices for similar assets and liabilities in active markets, quoted prices in markets that are not active, or 
inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability; or
•
Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and 
unobservable (i.e., supported by little or no market activity).
To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination 
of fair value requires more judgment. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any 
input that is significant to the fair value measurement.
Our cash equivalents and marketable debt securities are reported at fair value determined using Level 1 and Level 2 inputs (Note 6). 
The fair value of our foreign currency forward contracts is calculated using Level 2 inputs, which include currency spot rates, forward 
rates, interest rate curve and credit or non-performance risk. 
111

Inventory
Inventory is recorded at the lower of cost or net realizable value, with cost determined principally using first-in, first-out method. We 
periodically review the composition of inventory in order to identify excess, obsolete, slow-moving or otherwise unsaleable items. If 
unsaleable items are observed and there are no alternate uses for the inventory, we will record a write-down to net realizable value in 
the period that the decline in value is first recognized through a charge to cost of sales. The determination of whether inventory costs 
will be realizable requires estimates by management. If actual market conditions are less favorable than projected by management, 
additional write-downs of inventory may be required. We also assess whether we have any excess firm, non-cancelable, purchase 
commitment liabilities, resulting from our supply agreements with third-party vendors. The determination of net realizable value and 
firm purchase commitment liabilities requires judgment, including consideration of many factors, such as estimates of future product 
demand, product net selling prices, current and future market conditions, potential product obsolescence, expiration and utilization of 
raw materials under firm purchase commitments and contractual minimums, among others. We hold raw materials beyond our one 
year forecasted production plan, which were classified as non-current and included in other non-current assets in our consolidated 
balance sheets.
Pre-launch Inventory 
Costs relating to raw materials and production of inventory in preparation for product launch prior to regulatory approval are 
capitalized when future commercialization is considered probable, the future economic benefit is expected to be realized, and we 
believe that material uncertainties related to the ultimate regulatory approval have been significantly reduced. For pre-launch 
inventory that is capitalized, we consider a number of factors based on the information available at the time, including the product 
candidate’s current status in the drug development and regulatory approval process, results from the related clinical trials, results from 
meetings with relevant regulatory agencies prior to the filing of regulatory applications, potential impediments to the approval process 
such as product safety or efficacy, historical experience, viability of commercialization and market trends. As of December 31, 2024, 
we did not have any capitalized pre-launch inventory on our consolidated balance sheets. 
Property, Plant and Equipment
Property, plant and equipment are stated at cost, net of accumulated depreciation. Depreciation is calculated using the straight-line 
method over the estimated useful lives of the assets. The estimated useful lives of property, plant and equipment are described below:
Estimated Useful Life
Land and land improvements
Not depreciated
Buildings and building improvements
Up to 40 years
Manufacturing and laboratory equipment
5 years
Leasehold improvements
Lesser of estimated useful life of improvement
or remaining life of related lease
Computer equipment and software
3 to 5 years
Furniture, fixtures and other
5 years
Right-of-use asset, financing
Lease term
Construction in progress includes direct costs related to the construction of various property, plant and equipment, and is stated at 
original cost. Once the asset is placed into service, these capitalized costs will be allocated to certain property, plant and equipment 
categories and will be depreciated over the estimated useful life of the underlying assets. 
Goodwill and Intangible Assets 
Goodwill represents the excess of purchase price over the fair value of net assets acquired and is carried at cost. Goodwill is tested at 
least annually for impairment by assessing qualitative factors in determining whether it is more likely than not that the fair value of net 
assets is below their carrying amounts. To date, an impairment of goodwill has not been recorded. 
The fair value of acquired intangible assets is determined by applying the income-based approach, which is a valuation technique that 
provides an estimate of the fair value of an asset based on market participant expectations of the cash flows an asset would generate 
over its remaining useful life. To estimate the expected cash flows attributable to an intangible asset, it requires the use of Level 3 fair 
value measurements and inputs. Finite-lived intangible assets are amortized on a straight-line basis over their estimated useful lives. 
112

Impairment of Long-Lived Assets, including Intangibles and Lease Right-of-Use Assets
We evaluate our long-lived assets, which consist of property, plant and equipment, intangibles and right-of-use assets to determine if 
facts and circumstances indicate that the carrying amount of assets may not be recoverable. If such facts and circumstances exist, we 
assess the recoverability of the long-lived assets by comparing the projected future undiscounted net cash flows associated with the 
related asset or group of assets over their remaining lives against their respective carrying amounts. If such review indicates that such 
cash flows are not expected to be sufficient to recover the recorded value of the assets, the assets are written down to their estimated 
fair values based on the expected discounted future cash flows attributable to the assets or based on appraisals. Impairment expenses 
for the years ended December 31, 2024, 2023 and 2022 were immaterial.
Leases
Leases are classified at their commencement date, which is defined as the date on which the lessor makes the underlying asset 
available for use by the lessee, as either operating or finance leases based on the economic substance of the agreement. We recognize 
lease right-of-use assets and related liabilities in our consolidated balance sheets for both operating and finance leases. Lease liabilities 
are measured at the lease commencement date as the present value of the future lease payments using the interest rate implicit in the 
lease. If the rate implicit is not readily determinable, we will utilize our incremental borrowing rate as of the lease commencement 
date. Lease right-of-use assets are initially measured as the lease liability plus direct costs and prepaid lease payments less lease 
incentives. The lease term is the non-cancelable period of the lease and includes options to extend or terminate the lease when it is 
reasonably certain that an option will be exercised. 
We recognize operating lease cost in operating expenses in our consolidated statements of operations, inclusive of rent escalation 
provisions and rent holidays, on a straight-line basis over the respective lease term. For our finance leases, we recognize depreciation 
expense associated with the leased asset acquired and recognize interest expense related to the portion of the financing in our 
consolidated statements of operations. 
We do not separate non-lease components from lease components for all classes of underlying assets. We do not recognize right-of-
use assets and lease liabilities for leases with a lease term of 12 months or less. Instead, these lease payments are recognized in the 
statements of operations on a straight-line basis over the lease term.
Collaboration Arrangements
We analyze our collaboration arrangements to assess whether they are within the scope of ASC 808 (Collaborative Arrangements) to 
determine whether such arrangements involve joint operating activities performed by parties that are both active participants in the 
activities and exposed to significant risks and rewards that are dependent on the commercial success of such activities. To the extent 
the arrangement is within the scope of ASC 808, we assess whether aspects of the arrangement between us and our collaboration 
partner are within the scope of other accounting literature. If we conclude that some or all aspects of the arrangement represent a 
transaction with a customer, we account for those aspects of the arrangement within the scope of ASC 606 (Revenue from Contracts 
with Customers). Please refer to our "Revenue Recognition" policy within Note 2 for additional discussion of revenue recognition 
under these types of arrangements. If we conclude that some or all aspects of the arrangement are within the scope of ASC 808 and do 
not represent a transaction with a customer, we recognize our allocation of the shared costs incurred with respect to the jointly 
conducted activities as a component of the related expense in the period incurred. Additionally, for any payments related to capital 
expenditures that are partially reimbursed by a collaboration partner, to the extent the underlying capital costs qualify for 
capitalization, any reimbursements received will offset the capitalized cost of the asset.
Research and Development Funding Arrangements 
We have entered into a research and development funding arrangement to support a targeted program, under which a third party has 
committed to fund us up to a specified amount. Contingent upon the regulatory approval of the program, we are obligated to pay 
certain milestones and royalties as outlined in the agreement. We account for funding received under research and development 
arrangements as a reduction to expenses when substantive financial risk is transferred to the funding party. These arrangements are 
accounted for as an obligation to conduct research and development activities. The funding is recognized proportionally as the related 
costs are incurred, using an input method. Contingent payments, such as milestones or royalties, are recognized separately upon 
achievement of the related conditions.
113

Research and Development Costs
Research and development costs are expensed as incurred. Research and development expenses consist of costs incurred in performing 
research and development activities, including salaries and benefits, facilities costs, overhead costs, contract services, and other 
outside costs. The value of goods and services received from contract research organizations and contract manufacturing organizations 
in the reporting period are estimated based on the level of services performed, and progress in the period in cases when we have not 
received an invoice from the supplier. Research and development costs also include costs and shared cost associated with third-party 
collaboration arrangements, including upfront fees and milestones paid to third-parties in connection with technologies that had not 
reached technological feasibility and did not have an alternative future use. 
Assets that are acquired or constructed for research and development activities and that have alternative future uses, in research and 
development projects or otherwise, are capitalized and depreciated over their useful lives. However, the costs of equipment or 
facilities that are acquired or constructed and intangibles that are purchased from others for a particular research and development 
project, and that have no alternative future uses and therefore no separate economic values, are considered research and development 
costs and expensed when incurred. 
Advertising Costs
Costs associated with advertising are expensed as incurred and are included in selling, general and administrative expense in the 
consolidated statements of operations. Advertising expenses were $146 million in 2024, $204 million in 2023, and $121 million in 
2022. 
Stock-Based Compensation
We issue stock-based awards to employees and non-employees, generally in the form of stock options, restricted stock units (RSUs), 
and performance stock units (PSUs). We account for our stock-based compensation awards in accordance with ASC 718 
(Compensation—Stock Compensation). Most of our stock-based awards have been made to employees. We measure compensation 
cost for equity awards at their grant-date fair value and recognize compensation expense over the requisite service period, which is 
generally the vesting period, on a straight-line basis. The grant date fair value of stock options is estimated using the Black-Scholes 
option pricing model, which requires management to make assumptions with respect to the fair value of our common stock on the 
grant date, including the expected term of the award, the expected volatility of our stock, calculated based on a period of time 
generally commensurate with the expected term of the award, risk-free interest rates and expected dividend yields of our stock. We 
estimate the expected term of our stock options granted to employees and non-employees using the simplified method, whereby, the 
expected term equals the average of the vesting term and the original contractual term of the option. We utilize this method as we do 
not have sufficient historical exercise data to provide a reasonable basis upon which to estimate the expected term, and because 
significant changes in our business over the past few years have rendered historical experience less relevant. The expected volatility is 
based on a blended measure, which incorporates the historical stock volatilities of selected guideline companies, historical volatility of 
our stock price, and implied stock price volatility derived from the price of exchange traded options on our stock. We believe that this 
blended volatility rate is more indicative of future volatility than relying solely on our historical volatility alone, given the 
transformative changes in our business. We will continue to apply this process until a sufficient amount of historical information 
regarding the expected term and historical volatility of our own stock price becomes available, and until we believe that historical 
experience is relevant to our expectations for current grants. The grant date fair value of RSUs is estimated based on the fair value of 
our underlying common stock. For performance-based stock awards, we recognize stock-based compensation expense over the 
requisite service period using the accelerated attribution method when achievement is probable. We classify stock-based compensation 
expense in our consolidated statements of operations in the same manner in which the award recipient’s salary and related costs are 
classified or in which the award recipient’s service payments are classified. We made an accounting policy election to recognize 
forfeitures of stock-based awards as they occur.
Income Taxes
We account for income taxes based on an asset and liability approach. We recognize deferred tax assets and liabilities for the expected 
future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities. These 
differences are measured using the enacted statutory tax rates and laws that will be in effect when the differences are expected to 
reverse. Valuation allowances are provided when the expected realization of deferred tax assets does not meet a “more likely than not” 
criterion. We periodically reassess the need for valuation allowances on our deferred tax assets, considering both positive and negative 
evidence to evaluate whether it is more likely than not that all or a portion of such assets will not be realized. We make estimates and 
judgments about our future taxable income that are based on assumptions that are consistent with our plans and estimates. Should the 
actual amounts differ from our estimates, the amount of our valuation allowance could be materially impacted. Changes in these 
estimates may result in significant increases or decreases to our tax provision in a period in which such estimates are changed, which 
114

in turn would affect net income or loss. We recognize tax benefits from uncertain tax positions if we believe the position is more likely 
than not to be sustained on examination by the taxing authorities based on the technical merits of the position. We make adjustments 
to these tax reserves when facts and circumstances change, such as the closing of a tax audit or the refinement of an estimate. The 
provision for income taxes includes the effects of any reserves for uncertain tax positions, as well as the related net interest and 
penalties.
Earnings (Loss) per Share
We calculate diluted net earnings (loss) per share attributable to common stockholders by dividing net earnings (loss) by the weighted 
average number of common shares outstanding after giving consideration to the dilutive effect of restricted stock units, performance 
stock units, stock options, and shares under the employee stock purchase plan that are outstanding during the period. For periods in 
which we have generated a net loss, the basic and diluted net loss per share attributable to common stockholders are the same, as the 
inclusion of the potentially dilutive securities would be anti-dilutive.
Comprehensive Income (Loss)
Comprehensive income (loss) includes net income (loss) and other comprehensive income (loss) for the period. Other comprehensive 
income (loss) consists of unrealized gains and losses on our investments, derivatives designated as hedging instruments, and foreign 
currency translation, as well as, pension and postretirement obligation adjustments. Total comprehensive income (loss) for all periods 
presented has been disclosed in the consolidated statements of comprehensive income (loss).
The components of accumulated other comprehensive loss for the years ended December 31, 2024 and 2023 were as follows (in

Share Repurchases
Shares of our common stock repurchased pursuant to our repurchase programs are retired. The purchase price of such repurchased 
shares of common stock is recorded as a reduction to additional paid-in-capital. If the balance in additional paid-in-capital is 
exhausted, the excess is recorded as a reduction to retained earnings.
Recently Issued Accounting Standards 
From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies and adopted by us as of 
the specified effective date. Except as noted below, we believe that the impact of recently issued standards that are not yet effective 
will not have a material impact on our consolidated financial statements and disclosures.
In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment 
Disclosures. This ASU broadens the disclosure requirements by requiring disclosures of significant segment expenses that are 
regularly provided to the chief operating decision maker (CODM) and included within each reported measure of segment profit or 
loss. The standard also requires entities to disclose, on an interim and annual basis, the amount and description, including the nature 
and type, of the other segment items. Additionally, entities are required to disclose the title and position of the individual identified as 
the CODM and an explanation of how the CODM uses the reported measures of a segment’s profit or loss in assessing segment 
performance and deciding how to allocate resources. These enhanced disclosure obligations apply to entities that operate with one 
reportable segment as well. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within 
fiscal years beginning after December 15, 2024 on a retrospective basis. We adopted this ASU in the fourth quarter of 2024, and the 
adoption did not have a material impact on our consolidated financial statement disclosures.
115

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. This 
ASU requires disaggregated information about a reporting entity’s effective tax rate reconciliation as well as additional information on 
income taxes paid. The standard requires entities to disclose federal, state, and foreign income taxes in their rate reconciliation tables 
and elaborate on reconciling items that exceed a quantitative threshold. Additionally, it requires an annual disclosure of income taxes 
paid, net of refunds, categorized by jurisdiction based on a quantitative threshold. The ASU is effective on a prospective basis for 
annual periods beginning after December 15, 2024. Early adoption is permitted. This ASU will result in the required additional 
disclosures being included in our consolidated financial statements, once adopted.

As of December 31, 2024, we have two commercial products authorized for use, our COVID vaccine and our RSV vaccine. The RSV 
vaccine was approved by the FDA in May 2024 for adults aged 60 years and older and we commenced sales of our RSV vaccine in the 
third quarter of 2024. As of December 31, 2023 and 2022, our COVID vaccine was our only commercial product authorized for use. 
Prior to the third quarter of 2023, we sold our COVID vaccine to the U.S. Government, foreign governments and international 
organizations. The agreements and related amendments with these entities generally do not include variable consideration, such as 
discounts, rebates or returns. Certain of these agreements entitle us to upfront deposits for our COVID vaccine supply, initially 
recorded as deferred revenue. 
As of December 31, 2024 and 2023, we had deferred revenue of $188 million and $613 million, respectively, related to customer 
deposits. We expect $130 million of our deferred revenue related to customer deposits as of December 31, 2024 to be realized in less 
than one year. Timing of product delivery and manufacturing, and receipt of marketing approval for the applicable COVID vaccine 
will determine the period in which net product sales are recognized.
In the third quarter of 2023, we commenced sales of our COVID vaccine to the U.S. commercial market, in addition to continuing 
sales to foreign governments and international organizations. We also commenced sales of our RSV vaccine in the third quarter of 
2024. In the U.S., our COVID and RSV vaccines are sold primarily to wholesalers and distributors, and to a lesser extent, directly to 
retailers and healthcare providers. Wholesalers and distributors typically do not make upfront payments to us. 
Net product sales are recognized net of estimated wholesaler chargebacks, invoice discounts for prompt payments and pre-orders, 
provisions for sales returns and government rebates, and other related deductions.

Grant Revenue
In April 2020, we entered into an agreement with Biomedical Advanced Research and Development Authority (BARDA), a division 
of the Administration for Strategic Preparedness and Response (ASPR) within the U.S. Department of Health and Human Services 
(HHS), for an award of up to $483 million to accelerate development of mRNA-1273, our original vaccine candidate against 
COVID-19. The agreement has been subsequently amended to provide for additional commitments to support various late-stage 
clinical development efforts of mRNA-1273, including a 30,000 participant Phase 3 study, pediatric clinical trials, adolescent clinical 
trials and pharmacovigilance studies. The maximum award from BARDA, inclusive of all amendments, was approximately 
$1.8 billion. All contract options have been exercised. As of December 31, 2024, the remaining available funding, net of revenue 
earned was $63 million.
In June 2024, we were awarded up to $176 million through the Rapid Response Partnership Vehicle (RRPV), funded by BARDA, to 
accelerate the development of mRNA-based pandemic influenza vaccines. The project award will support the late-stage development 
of an mRNA-based vaccine to enable the licensure of a pre-pandemic vaccine against the H5 influenza virus. This subtype of the 
influenza virus causes a highly infectious and severe disease in birds known as avian influenza and poses a risk of spillover into the 
human population. The agreement also includes additional options to prepare for and accelerate responses to future public health 
threats. Revenue recognized related to this agreement was immaterial as of December 31, 2024.

Licensing and Royalty Revenue 
In April 2024, we entered a non-exclusive out-licensing agreement with a pharmaceutical company based in Japan for mRNA 
COVID-related intellectual property for the territory of Japan. Under the terms of the agreement, we received an upfront payment of 
$50 million, which included a $20 million prepayment creditable against future royalties. Additionally, we are entitled to receive low 
double-digit royalties on the net sales of the company’s COVID product. 
Upon execution of the agreement, we recognized $30 million of the upfront payment as other revenue in our consolidated statements 
of operations. The remaining $20 million was recorded as deferred revenue in our consolidated balance sheets. In the third quarter of 
2024, we began recognizing royalty revenue by amortizing the deferred revenue as the underlying sales occurred. 
5. Collaboration Agreements and Research and Development Funding Arrangement
Development and Commercialization Funding Arrangement with Blackstone Life Sciences (Blackstone)
In March 2024, we entered into a development and commercialization funding arrangement with Blackstone, under which Blackstone 
has committed to providing up to $750 million in funding to us. This funding supports the development of our investigational mRNA-
based influenza vaccine. Contingent upon regulatory approval in the U.S. and only if the approval is dependent on data from the 
funded activities, Blackstone will be entitled to receive low single-digit percentage royalties and up to $750 million in sales milestone 
payments. These payments are based on net sales of our future influenza and combination vaccines, with sales milestone payments 
contingent upon achieving specified cumulative net sales targets. 
Given the substantive transfer of financial risk to Blackstone, we account for this arrangement as an obligation to conduct research and 
development activities. The funding is recognized as a reduction to the expenses of our mRNA-based influenza program. This 
reduction is recognized proportionally as the related costs are incurred, based on an input method. For the year ended December 31, 
2024, we recorded research and development expense reductions of $267 million. As of December 31, 2024, we had a research and 
development funding liability of $58 million related to the advance funding received from Blackstone.
Merck – Personalized mRNA Cancer Vaccines (Individualized Neoantigen Therapy)
In June 2016, we entered into a Collaboration and License Agreement for the development and commercialization of personalized 
mRNA cancer vaccines (also known as INT) with Merck, to develop and commercialize INTs for individual patients using our mRNA 
118

and formulation technology. This agreement was subsequently amended and restated in 2018 (INT Agreement). Our role in this 
strategic alliance involves identifying genetic mutations in a particular patient’s tumor cells, synthesizing mRNA for these mutations, 
encapsulating the mRNA in one of our proprietary lipid nanoparticles (LNPs), and administering a unique mRNA INT to each patient. 
Each INT is designed to specifically activate the patient’s immune system against her or his own cancer cells. 
Pursuant to the INT Agreement, we received an upfront payment of $200 million from Merck and we were responsible for designing 
and researching INTs, providing manufacturing capacity and manufacturing INTs and conducting Phase 1 and Phase 2 clinical trials 
for INTs, alone and in combination with KEYTRUDA (pembrolizumab), Merck’s anti-PD-1 therapy, all in accordance with an agreed 
upon development plan and budget. We concluded that the collaboration arrangement was governed by the revenue recognition 
standard ASC 606. 
In September 2022, Merck exercised its option for INT, including mRNA-4157, pursuant to the terms of the agreement and in October 
2022 paid us an option exercise fee of $250 million. Following this exercise, the Merck Participation Term commenced. Pursuant to 
the agreement, we and Merck have agreed to collaborate on development and potential commercialization of INT, with costs and any 
profits or losses generally shared equally on a worldwide basis, subject to certain exceptions as outlined in the agreement. We 
concluded that the collaboration arrangement under the Merck Participation Term is within the scope of ASC 808. For the years ended 
December 31, 2024, 2023 and 2022, we recognized expense of $390 million, $184 million, and $6 million, respectively, net of 
Merck's reimbursements, related to the INT collaboration under the Merck Participation Term. Additionally, the net cost recovery for 
capital expenditures during the same periods were $109 million, $102 million, and $3 million, respectively, which were applied to 
reduce the capitalized cost of the assets.
Vertex – Strategic Alliance in Cystic Fibrosis
In July 2016, we entered into a Strategic Collaboration and License Agreement (Vertex Agreement), with Vertex Pharmaceuticals 
Incorporated, and Vertex Pharmaceuticals (Europe) Limited, together, Vertex. The Vertex Agreement, which was amended in July 
2019 (2019 Vertex Amendment), is aimed at the discovery and development of potential mRNA medicines for the treatment of cystic 
fibrosis (CF) by enabling cells in the lungs of people with CF to produce functional cystic fibrosis transmembrane conductance 
regulator (CFTR) proteins. Pursuant to the Vertex Agreement, we lead discovery efforts during an initial research period, leveraging 
our platform technology and mRNA delivery expertise along with Vertex’s scientific experience in CF biology and the functional 
understanding of CFTR. Vertex is responsible for conducting development and commercialization activities for candidates and 
products that arise from the strategic alliance, including the costs associated with such activities. Subject to customary “back-up” 
supply rights granted to Vertex, we exclusively manufacture (or have manufactured) mRNA for preclinical, clinical and 
commercialization purposes. This collaboration arrangement is accounted for under ASC 606 and currently ongoing. 
Immatics – Strategic Multi-Platform Collaboration to Develop Oncology Therapeutics
In September 2023, we entered into a strategic collaboration with Immatics to jointly develop cancer vaccines and TCER® 
therapeutics, with Immatics leading preclinical and early clinical studies and Moderna leading later-stage development and 
commercialization. Upon effectiveness of the agreement in October 2023, we made an upfront payment of $120 million, recognized as 
research and development expense. Immatics is also eligible for research funding, milestone payments, tiered royalties on global net 
sales of TCER® products and certain vaccine products that are commercialized under the agreement. Additionally, Immatics has an 
option to enter into a global profit and loss share arrangement for the most advanced TCER®.
In addition to the collaborative arrangements mentioned above, we have other collaborative and licensing arrangements that we do not 
consider to be individually significant to our business at this time. Pursuant to these agreements, we may be required to make upfront 
payments and payments upon achievement of various development, regulatory and commercial milestones, which in the aggregate 
could be significant. Future milestone payments, if any, will be reflected in our consolidated financial statements when the 
corresponding events become probable. In addition, we may be required to pay significant royalties on future sales if products related 
to these arrangements are commercialized.

At December 31, 2024 and 2023, we held 252 and 392 available-for-sale securities, respectively, out of our total investment portfolio 
that were in a continuous unrealized loss position. We neither intend to sell these investments nor conclude that we are more-likely-
than-not that we will have to sell them before recovery of their carrying values. We also believe that we will be able to collect both 
principal and interest amounts due to us at maturity.

_______
(1)Investments in publicly traded equity securities with readily determinable fair values are recorded at quoted market prices for 
identical securities, with changes in fair value recorded in other expense net, in our consolidated statements of operations.
As of December 31, 2024 and 2023, we did not have non-financial assets or liabilities measured at fair value on a recurring basis.
For the years ended December 31, 2024 and 2023, we recognized net losses of $52 million and $35 million, respectively, on equity 
investments from changes in fair value of the securities. We did not have equity investments in publicly traded securities with readily 
determinable fair values during 2022. 
In addition, as of December 31, 2023, we had $42 million in equity investments without readily determinable fair values, which are 
recorded within other non-current assets in our consolidated balance sheets and excluded from the fair value measurement tables 
above. These investments became publicly traded during the first quarter of 2024 and were recorded at their quoted market price in our 
consolidated balance sheets as of December 31, 2024.

_______
(1)Consisted of raw materials with an anticipated consumption beyond one year. Inventory, non-current is included in other non-current 
assets in the consolidated balance sheets. 
Inventory write-downs as a result of excess, obsolescence, scrap or other reasons, and losses on firm purchase commitments are 
recorded as a component of cost of sales in our consolidated statements of operations. For the years ended December 31, 2024, 2023, 
and 2022, inventory write-downs were $495 million, $2.2 billion, and $1.3 billion, respectively. For the years ended December 31, 
2024, 2023, and 2022, losses on firm purchase commitments were $60 million, $141 million, and $617 million, respectively. 
Inventory write-downs were mainly related to inventory in excess of expected demand and shelf-life expiration. Losses on firm 
purchase commitments were primarily related to excess raw material purchase commitments that will expire before the anticipated 
consumption of those raw materials. These charges in 2024 were primarily driven by the shift to a seasonal model for the COVID 
vaccine market, along with a decline in overall customer demand and excess inventory.
In the third quarter of 2023, we completed our long-range financial planning process, incorporating revised forecasts of vaccination 
rates. This resulted in the reassessment of future demand for our COVID vaccine, leading to a strategic initiative to resize our 
manufacturing cost structure. This initiative, launched in the same quarter, involved reassessing our inventory levels and renegotiating 
with our suppliers to reduce our purchase commitments related to raw materials which were not expected to be consumed before 
expiration. This initiative resulted in a raw materials write-down of $903 million, included in the total inventory write-down amount 
for the quarter.
As of December 31, 2024 and December 31, 2023, the accrued liability for losses on firm future purchase commitments in our 
consolidated balance sheets was $60 million and $79 million, respectively. As of December 31, 2024 and December 31, 2023, we had 
inventory on hand of $267 million and $372 million, respectively, inclusive of inventory for our COVID and RSV vaccines. Our raw 
materials and work-in-progress inventory have variable shelf lives. We expect that the majority of this inventory will be consumed 
over the next three years. The shelf life of our COVID vaccine product ranges from nine to twelve months. The shelf life of our RSV 
vaccine is 18 months.

10. Leases
We have entered into various long-term non-cancelable lease arrangements for our facilities and equipment expiring at various times 
through 2039. Certain of these arrangements have free rent periods or escalating rent payment provisions. We recognize lease cost 
under such arrangements on a straight-line basis over the life of the leases. We have two main campuses in Massachusetts, our 
Moderna Science Center (MSC), located in Cambridge, which serves as our headquarters, and our Moderna Technology Center 
(MTC), located in Norwood. We also lease various parcels of land, office, lab, and manufacturing spaces across the globe for our 
business operations.
Moderna Science Center
Our Cambridge campus previously included multiple leased properties at Technology Square and the MSC, a facility comprising 
approximately 462,000 square feet that serves as our principal executive office, along with additional office and laboratory spaces. 
The MSC lease, which commenced during the third quarter of 2023, has a term of 15 years with options for two additional seven-year 
extensions. During the fourth quarter of 2023, we amended the expiration dates of our Technology Square leases to conclude in 
January 2025, as we transitioned operations to the MSC. As of December 31, 2024, we substantially exited our leased spaces at 
Technology Square, completing the consolidation of our Cambridge operations into the MSC.
Moderna Technology Center
The MTC is a multiple-building campus spanning approximately 722,000 square feet that previously operated under long-term finance 
leases expiring in 2042, with options for three five-year extensions. The MTC has been a critical facility for our manufacturing, 
laboratory, and office operations. In December 2024, we completed the acquisition of the MTC campus, including the underlying land 
and buildings, for a total purchase price of $385 million. Upon acquisition, we derecognized the right-of-use assets and lease liabilities 
associated with the Norwood leases. The purchase price, after adjustments related to lease terminations, was allocated to land and 
buildings, with approximately $231 million recorded as property, plant, and equipment on our consolidated balance sheets as of 
December 31, 2024.

11. Commitments and Contingencies
Legal Proceedings
We are involved in various claims and legal proceedings of a nature considered ordinary course in our business. The outcome of any 
such proceedings, regardless of the merits, is inherently uncertain; therefore, assessing the likelihood of loss and any estimated 
damages is difficult and subject to considerable judgment. We are not currently a party to any legal proceedings for which a material 
loss is probable, or for which a loss is reasonably estimable at this time.
Indemnification Obligations
As permitted under Delaware law, we indemnify our officers, directors, and employees for certain events, occurrences while the 
officer, or director is, or was, serving at our request in such capacity. The term of the indemnification is for the officer’s or director’s 
lifetime.
We have standard indemnification arrangements in our leases for laboratory and office space that require us to indemnify the landlord 
against any liability for injury, loss, accident, or damage from any claims, actions, proceedings, or costs resulting from certain acts, 
breaches, violations, or non-performance under our leases.
We enter into indemnification provisions under our agreements with counterparties in the ordinary course of business, typically with 
business partners, contractors, clinical sites and customers. Under these provisions, we generally indemnify and hold harmless the 
indemnified party for losses suffered or incurred by the indemnified party as a result of our activities. These indemnification 
provisions generally survive termination of the underlying agreement. The maximum potential amount of future payments we could be 
required to make under these indemnification provisions is unlimited.
Through December 31, 2024 and 2023, we had not experienced any significant losses related to these indemnification obligations, and 
no material claims were outstanding. We do not expect significant claims related to these indemnification obligations and, 
consequently, concluded that the fair value of these obligations is negligible, and no related reserves were established.
Purchase Commitments and Purchase Orders
We enter into agreements in the normal course of business with vendors and contract manufacturing organizations (CMOs) for raw 
materials and manufacturing services and with vendors for preclinical research studies, clinical trials and other goods or services. As 
of December 31, 2024, we had $809 million of non-cancelable purchase commitments related to raw materials and manufacturing 
agreements, which are expected to be paid through 2027. This amount includes $60 million of the purchase commitments related to 
raw materials that was recorded as an accrued liability for loss on future firm purchase commitments. As of December 31, 2024, we 
had $236 million of non-cancelable purchase commitments related to research and development and other goods and services which 
are expected to be paid through 2029. These amounts represent our minimum contractual obligations, including termination fees.
In addition to purchase commitments, we have agreements with third parties for various services, including services related to clinical 
operations and support and contract manufacturing, for which we are not contractually able to terminate for convenience and avoid 
any and all future obligations to the vendors. Certain agreements provide for termination rights subject to termination fees or wind-
down costs. Under such agreements, we are contractually obligated to make certain payments to vendors, mainly, to reimburse them 
for their unrecoverable outlays incurred prior to cancellation. At December 31, 2024, we had cancelable open purchase orders of $2.9 
billion in total under such agreements for our significant clinical operations and support and contract manufacturing. These amounts 
represent only our estimate of those items for which we had a contractual commitment to pay at December 31, 2024, assuming we 
would not cancel these agreements. The actual amounts we pay in the future to the vendors under such agreements may differ from the 
purchase order amounts.
Licenses to Patented Technology
In 2017, we entered into sublicense agreements with Cellscript, LLC and its affiliate, mRNA RiboTherapeutics, Inc. to sublicense 
certain patent rights. Pursuant to each agreement, we are required to pay certain license fees, annual maintenance fees, minimum 
royalties on future net sales and milestone payments contingent on achievement of certain development, regulatory and commercial 
milestones for specified products, on a product-by-product basis. Commercial milestone payments and royalties based on annual net 
sales of licensed products for therapeutic and prophylactic products are accounted for as additional expense of the related net product 
sales in the period in which the corresponding sales occur. 
In December 2022, we entered into a non-exclusive patent license agreement with the National Institute of Allergy and Infectious 
Diseases (NIAID), an Institute or Center of the National Institutes of Health (NIH) to license certain patent rights concerning 
129

stabilizing prefusion coronavirus spike proteins and the resulting stabilized proteins for use in COVID vaccine products. Pursuant to 
the agreement, we have agreed to pay low single-digit royalties on future net sales, a minimum annual royalty payment, and certain 
contingent development, regulatory and commercial milestone payments on a licensed product-by-licensed product basis. In addition, 
in December 2022, we made a catch-up royalty payment of $400 million to NIAID, which was recorded to cost of sales in our 
consolidated statements of operations. 
For the years ended December 31, 2024, 2023, and 2022 we recognized $155 million, $301 million, and $1.1 billion, respectively, of 
royalties and commercial milestone payments associated with our net product sales, which was recorded to cost of sales in our 
consolidated statements of operations.
Additionally, we have other in-license agreements with third parties which require us to make future development, regulatory and 
commercial milestone payments for specified products associated with the agreements. The achievement of these milestones have not 
yet occurred as of December 31, 2024. 
12. Stock-Based Compensation and Share Repurchase Programs
Equity Plans
In connection with our initial public offering (IPO), we adopted the 2018 Stock Option and Incentive Plan (the 2018 Equity Plan) in 
November 2018. The 2018 Equity Plan became effective on the date immediately prior to the effective date of the IPO and replaced 
our 2016 Stock Option and Incentive Plan (the 2016 Equity Plan). The 2018 Equity Plan provides flexibility to our compensation 
committee to use various equity-based incentive awards as compensation tools to motivate our workforce. The shares of common 
stock underlying any awards that are forfeited, canceled, held back upon exercise or settlement of an award to satisfy the exercise 
price or tax withholding, reacquired by us prior to vesting, satisfied without any issuance of stock, expire or are otherwise terminated 
(other than by exercise) under the 2018 Equity Plan and the 2016 Equity Plan will be added back to the shares of common stock 
available for issuance under the 2018 Equity Plan.
The Board of Directors may grant to employees, nonemployee directors, consultants and independent advisors equity-based awards 
during their period of service, generally in the form of stock options, restricted stock units, and performance stock units. The terms and 
conditions of stock-based awards are defined at the sole discretion of our Board of Directors. We issue service-based awards, vesting 
over a defined period of service, and performance-based awards, vesting upon achievement of defined conditions. Service based 
awards generally vest over a four-year period, with the first 25% of such awards vesting following twelve months of continued 
employment or service. The remaining awards vest in twelve quarterly installments over the following twelve quarters. Stock options 
granted under the 2018 Equity Plan and the 2016 Equity Plan expire ten years from the date of grant and the exercise price must be at 
least equal to the fair market value of common stock on the grant date.
As of December 31, 2024, we had a total of 59 million shares reserved for future issuance under our Equity Plans, of which 34 million 
shares were reserved for equity awards previously granted, and 25 million shares were available for future grants under the 2018 
Equity Plan. No additional awards will be granted under the 2016 Equity Plan as it was replaced by the 2018 Equity Plan.

(1)Aggregate intrinsic value is calculated as the difference between the exercise price of the underlying options and the fair value of 
common stock for those options in the money as of December 31, 2024.
The total intrinsic value of options exercised was $122 million, $413 million, and $714 million for the years ended December 31, 
2024, 2023, and 2022, respectively. The aggregate intrinsic value represents the difference between the exercise price and the selling 
price received by option holders upon the exercise of stock options during the period. The excess tax benefits realized from tax 
deductions from option exercises were $24 million, $84 million, and $144 million during the years ended December 31, 2024, 2023, 
and 2022, respectively. The total consideration recorded as a result of stock option exercises was approximately $42 million, $25 
million, and $50 million, respectively, for the years ended December 31, 2024, 2023, and 2022.
Restricted Common Stock Units (RSUs) and Performance Stock Units (PSUs)
We have granted RSUs and PSUs generally through the 2018 Equity Plan. The following table summarizes our RSU and PSU activity 
during the year ended December 31, 2024:

The total grant date fair value of RSUs and PSUs vested during the years ended December 31, 2024, 2023, and 2022, was $228 
million, $99 million, and $55 million, respectively. The total intrinsic value of RSUs and PSUs vested during the years ended 
December 31, 2024, 2023, and 2022, was $161 million, $120 million and $125 million, respectively.
During 2024, 2023 and 2022, we granted an immaterial amount of PSUs, respectively, primarily to certain senior executives with 
vesting that is contingent upon the achievement of specified preestablished goals over the performance period, generally three years. 
The actual number of common shares ultimately issued is calculated by multiplying the number of PSUs by a payout percentage 
ranging from 0% to 200%. The estimated fair value of PSUs is based on the grant date fair value.

and 2022.
As of December 31, 2024, there were $820 million of total unrecognized compensation cost related to non-vested stock-based 
compensation with respect to options, RSUs and PSUs granted. That cost is expected to be recognized over a weighted-average period 
of 2.5 years at December 31, 2024.
Share Repurchase Programs
On February 22, 2022, our Board of Directors authorized a share repurchase program of our common stock for up to $3.0 billion, with 
no expiration date. On August 1, 2022, our Board of Directors authorized an additional $3.0 billion under the repurchase program, 
with no expiration date (collectively with the February 22, 2022 authorization, the 2022 Repurchase Programs). 
As of December 31, 2024, $1.7 billion of our Board of Directors’ authorization for repurchases of our common stock remains 
outstanding under the 2022 Repurchase Programs, with no expiration date. The timing and actual number of shares repurchased under 
the 2022 Repurchase Programs will depend on a variety of factors, including price, general business and market conditions, and other 
investment opportunities, and shares may be repurchased through open market purchases through the use of trading plans intended to 
qualify under Rule 10b5-1 under the Securities Exchange Act of 1934, as amended.

Our effective tax rate for the year ended December 31, 2024 was 1.3% and was lower than the federal statutory tax rate, primarily due 
to an increase in valuation allowance against deferred tax assets, which limited the recognition of tax benefits on our pre-tax loss. The 
tax benefits from research and development credits provided a partial offset. For the year ended December 31, 2023, despite being in a 
pre-tax loss position, our effective tax rate exceeded the federal statutory tax rate, primarily due to the establishment of a valuation 
allowance against the majority of the deferred tax assets, which resulted in a net tax expense rather than a benefit. This was partially 
offset by tax benefits from research and development credits and stock-based compensation. For the year ended December 31, 2022, 
when we were in a net income position, our effective tax rate was lower than the federal statutory tax rate, primarily due to the tax 
benefit of the foreign-derived intangible income deduction (FDII) and excess tax benefit related to stock-based compensation. 
As of January 1, 2022, pursuant to the Tax Cuts and Jobs Act of 2017 (TCJA), research and development costs in the current period 
are required to be amortized over five or fifteen years, depending on where the research is conducted. The new capitalization 
requirement significantly increased our deferred tax assets and cash tax liabilities, but also decreased our effective tax rate by 
increasing the foreign-derived intangible income deduction.
The President signed into law the Inflation Reduction Act (the IRA) on August 16, 2022. The Act includes a new 15% corporate 
minimum tax and a 1% excise tax on the value of corporate stock repurchases, net of new share issuances, after December 31, 2022. 
We do not expect these provisions to have a material impact on our consolidated financial position; however, we will continue to 
evaluate their impact as further information becomes available.
Deferred income taxes reflect the tax effect of temporary differences between the carrying amount of assets and liabilities for financial 
reporting and the amounts used for income tax purposes, tax credit carryforwards and the tax effect of net operating loss 
carryforwards. Significant components of our deferred tax assets and tax liabilities as of December 31, 2024 and 2023 were as follows

We periodically reassess the need for valuation allowances on our deferred tax assets, considering both positive and negative evidence 
to evaluate whether it is more likely than not that all or a portion of such assets will not be realized. During 2023, following the 
completion of our long-range financial planning process, we reassessed the evidence and concluded that a valuation allowance was 
necessary due to the preponderance of negative evidence, including: 
•
A pre-tax loss for the full year 2023, serving as a significant source of objectively verifiable negative evidence in accordance 
with ASC 740 (Income Taxes).
•
A projected three-year cumulative loss resulting from our long-range financial planning process. This projection was due to a 
significant decrease in expected sales of our COVID vaccine as we transitioned to a seasonal market. Additionally, we 
anticipated substantial research and development expenses for our on-going Phase 3 clinical trials and to advance our product 
candidates into later-stage development. These factors contributed additional negative evidence with respect to the 
realizability of our deferred tax assets. The projections were based upon revenue from our approved drug product, which we 
believe can be reasonably estimated. In contrast, future taxable income projections from our investigational medicines are 
deemed inherently subjective and not objectively verifiable; they are insufficient to override negative evidence, and therefore, 
they were not assigned any weight in our valuation allowance analysis assessment.
Our evaluation also included whether there were other sources of taxable income that would allow us to realize our deferred tax assets, 
such as taxable income in carryback years, available tax planning strategies and the future reversals of taxable temporary differences. 
After assessing these strategies and all evidence, we determined it was more likely than not that we will not realize all of our deferred 
tax assets and therefore increased the valuation allowance by $2.1 billion during 2023.
In 2024, we continued to maintain a global valuation allowance against the majority of our deferred tax assets, consistent with the 
assessment established in 2023. The valuation allowance reflects the ongoing preponderance of negative evidence, including 
continued and projected losses. 
Significant management judgment is required in assessing the realizability of our deferred tax assets. In the event that actual results 
differ from our estimates, we adjust our estimates in future periods and we may need to modify our valuation allowance, which could 
materially impact our financial position and results of operations.
At December 31, 2024, we had $1.3 billion and $2.5 billion of federal and state net operating loss carryforwards, respectively, of 
which $1.3 billion and $1.3 billion, respectively, will not expire and $1.1 billion of state net operating loss carryforwards will begin to 
expire in 2032. At December 31, 2024, we also had federal and state research and development tax credit carryforwards of $98 million 
and $194 million, respectively, the majority of which will begin to expire in 2030.

We recognize, in our financial statements, the effect of a tax position when it is more likely than not, based on the technical merits, 
that the position will be sustained upon examination. A reconciliation of the beginning and ending amounts of unrecognized tax 
benefits during the years ended December 31, 2024, 2023, and 2022 were as follows (in millions):

As of December 31, 2024, we had $240 million of net unrecognized tax benefits, which would affect our tax rate if recognized. 
Unrecognized tax benefits may change during the next twelve months for items that arise in the ordinary course of business. We do 
not anticipate a material change to our unrecognized tax benefits over the next twelve months that would have an adverse effect on our 
consolidated operating results. We recognize interest and penalties, if applicable, related to uncertain tax positions as a component of 
income tax expense. 
We file U.S. federal income tax returns and income tax returns in various state, local and foreign jurisdictions. All tax years since our 
date of incorporation remain open to examination by the major taxing jurisdictions, as carryforward attributes generated in past years 
may be adjusted upon examination by the Internal Revenue Service or the state authorities. As of December 31, 2024, we are under 
audit in various state and foreign jurisdictions; however, no adjustments to our tax positions have been proposed at this time.
14. (Loss) Earnings per Share
The computation of basic earnings (loss) per share (EPS) is based on the weighted-average number of our common shares outstanding. 
The computation of diluted EPS is based on the weighted-average number of our common shares outstanding and potential dilutive 
common shares outstanding during the period as determined by using the treasury stock method.
Basic and diluted EPS for the years ended December 31, 2024, 2023 and 2022 were calculated as follows (in millions, except per

In January 2025, we were awarded up to $590 million through the RRPV, funded by BARDA. This award supports the late-stage 
development and licensure of mRNA-based pre-pandemic influenza vaccines and the expansion of clinical studies for up to five 
additional subtypes of pandemic influenza. This funding builds upon the $176 million award we received in June 2024 from the RRPV 
to support the development of an mRNA-based vaccine against the H5 influenza virus. Please refer to Note 4 to our consolidated 
financial statements for further details.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure
None.
Item 9A. Controls and Procedures 
Evaluation of Disclosure Controls and Procedures
Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, evaluated the effectiveness of 
our disclosure controls and procedures as of December 31, 2024. The term “disclosure controls and procedures,” as defined in Rules 
13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, or the Exchange Act, means controls and other procedures of a 
company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under 
the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. 
Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to 
be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the 
company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions 
regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, 
can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the 
cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as 
of December 31, 2024, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls 
and procedures were effective at the reasonable assurance level.
Management’s Report on Internal Control Over Financial Reporting
Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as such term is 
defined in Exchange Act Rule 13a-15(f)) to provide reasonable assurance regarding the reliability of our financial reporting and the 
preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Management 
assessed our internal control over financial reporting as of December 31, 2024. Management based its assessment on criteria 
established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway 
Commission (2013 Framework). Based on that evaluation, our management concluded that our internal control over financial 
reporting was effective as of December 31, 2024. 
The effectiveness of our internal control over financial reporting as of December 31, 2024 has been audited by Ernst & Young LLP, an 
independent registered public accounting firm, as stated in their report included in this Annual Report on Form 10-K.
Changes in Internal Controls over Financial Reporting
During the three months ended December 31, 2024, there were no changes in our internal control over financial reporting (as defined 
in Rules 13a-15(f) and 15d-15(f) under the Exchange Act), which have materially affected, or are reasonably likely to materially 
affect, our internal control over financial reporting.
Inherent Limitations on the Effectiveness of Controls
Our management, including our Chief Executive Officer and Chief Financial Officer, believe that our disclosure controls and 
procedures and internal control over financial reporting are designed to provide reasonable assurance of achieving their objectives and 
are effective at the reasonable assurance level. However, our management does not expect that our disclosure controls and procedures 
or our internal control over financial reporting will prevent all errors and all fraud. A control system, no matter how well-conceived 
and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the 
design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered 
relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute 
assurance that all control issues and instances of fraud, if any, have been detected. These inherent limitations include the realities that 
judgments in decision making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, 
controls can be circumvented by the individual acts of some persons, by the collusion of two or more people or by a management 
override of the controls. The design of any system of controls also is based in part upon certain assumptions about the likelihood of 
future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future 
conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or 
procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud 
may occur and not be detected.

Report of Independent Registered Public Accounting Firm
To the Stockholders and the Board of Directors of Moderna, Inc.
Opinion on Internal Control Over Financial Reporting
We have audited Moderna, Inc.’s internal control over financial reporting as of December 31, 2024, based on criteria established in 
Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 
framework) (the COSO criteria). In our opinion, Moderna, Inc. (the Company) maintained, in all material respects, effective internal 
control over financial reporting as of December 31, 2024, based on the COSO criteria.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(PCAOB), the consolidated balance sheets of the Company as of December 31, 2024 and 2023, the related consolidated statements of 
operations, comprehensive income (loss), stockholders’ equity, and cash flows for each of the three years in the period ended 
December 31, 2024, and the related notes and our report dated February 21, 2025 expressed an unqualified opinion thereon.
Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of 
the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control 
Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based 
on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the 
Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange 
Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit 
to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.
Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness 
exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such 
other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our 
opinion.
Definition and Limitations of Internal Control Over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of 
financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting 
principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the 
maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the 
company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in 
accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in 
accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding 
prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect 
on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections 
of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in 
conditions, or that the degree of compliance with the policies or procedures may deteriorate.
